Full Text	System for the flexible production of a plurality of types of moulded food products. particularly chocolate-based products and the like The present invention relates in a general way to a system for the flexible production of moulded food products of the kind defined in the preamble of claim 1. Ve-0O5/iO748I diaduses a-sjtem Of this kind for the'production ot human food products such as products moulded from a meat mass, for instance hamburgers. The system involyes the use of a pltirality of types of mould drums, each for the production of a single corresponding kind of products. The mould drums are provided with respective pluralities of through or passing cavities, and a meat mass is passed therethrough under pressure, forming moulded products like hamburgers, which drop firom each mould dnim onto an underlying belt conveyor. in the technology used for the production of moulded food products, such aa chocolntefl with or without fillings, pralines and the like, various products may frequently have the same structure but differ in the characteristics of one or more of their constituents, For example, a "family" of products of this kind may have a common structure, including a shell formed by a pair of half-shells or wafer sheets, provided with an outer coating and containing a filling and a dried fruit or nut. For such a "family", it is possible to make differentiated products, currently referred to as different "flavours", by varying the filling and/or the associated dried fruit or nut (which may be, for example, an almond, a hazel-nut or a pistachio) and/or by varying the outer coating or a gamish thereon, made for example by applying and/or incorporating chopped meringue and/or hazel-nut or grated coconut (known as "sprinkles"). For the manufacture of such families of products, the production systems used at present require a specific batch production process for each product or "flavour" (using different shaping machines, or using the same machine at different times), these products then being set aside and subsequoitly collected, for example, in order to form "mixed" packages with the requisite combinations of "flavours". "his production method is not particularly efficient. }ne object of the present invention is to propose a system for the flexible and substantially imultaneous production of a plurality of types of moulded food products which differ ipom each other, while overcoming the drawbacks of the systems used up to the present ime. rhese and other objects ane achieved according to the invention widi a system according to ;laim 1. rhe memory devices associated with the moulds are conveniently of the rewriteable type, uid the system also comprises a final "validation" and cancellation station, which can :electively cancel information or data in the memory devices of the mould passing through it on each occasion. Further characteristics and advantages of the invention will be made clear by the following detailed description, provided purely by way of non-limiting example, with reference to the appended drawings, in which: Figure 1 is a schematic perspective view of a flexible production system according to the present invention; Figure 2 Ls a partial perspective view which shows a portion of a mould used in a flexible production system according to the present invention; Figure 3 is a schematic representation showing successive operations carried out in a flexible production system according to Figure 1; Figure 4 is a block diagram showing the architectiu'C of electronic units associated with various stations of a flexible production system according to the invention; and Figure S is a schematic representation showing a wrapping and packaging system which can be associated with a flexible production system according to the invention, and particularly with the system shown in Figures 1 and 3. In Figure 1, the number 1 indicates the whole of a system according to the invention for the flexible production of a plurality of types of moulded food products which differ from each other, for example, in their shape and/or their composition. In the illustrated example of embodiment, the system 1 comprises a conveyor 2 for conveying in sequence a plurality of moulds M along an essentially loop-shaped production path, on which is located a plurality of stations or devices Si-SI 6, each designed to execute at least one corresponding operation. With reference to Figure 2, in the illustrated example each mould M has a corresponding plurality of housings or cells 3 for forming corresponding moulded products such &a filled chocolates and the like. Each mould M carries a corresponding electronic identificatbn device, indicated ns a whole by T in Figure 2. This device, which may be what is known as an RFID, includes integrated electronic memory devices 4, from and to which information or data can be road and written, and if necessary rewritten, without contact, by means of an associated antenna or the like 5. The identification device T associated with each mould M can also comprise a microprocessor 6 and if necessary one or more sensors 7 for supplying electrical signals indicating the value of a corresponding physical and/or chemical quantity which is monitored, such as temperature or nooisture content, this value being writeable to the associated memory devices 4 and/or being directly transmitted to the electronic unit of one or more stations SI-S16, which are described below with reference to Figure 4. The identificaHon device T in the drawing is shown in a position adjacent to lite mould M, but it could also be "embedded" or otherwise incorporated into the mould itself. An interface circuit 8 can be interposed between the antenna S and the microprocessor 6, if the latter is present. The example illustrated in Figure I shows sixteen stations SI-SI 6, each of which is associated with a correonding electronic unit which, as described more fully below, includes a processor with associated memory devices and at least one antenna or the like. This processor is designed to read and/or write inforaiation or data from or to the memory devices 4 of each mould M passing through the station. In particular, the station SI is an initial input station. It is associated with an electronic unit indicated by A in Figures 1 and 4. This unit comprises a processor 9 with associated memory devices 10. The processor 9 is connected to a communications interface device 11 connected by a communication line 12 to an in-house communication networic. The microprocessor 9 is connected to at (east one antenna or the like 15 by means of transmission interftce devices indicated as a whole by 13. The electronic unit A of the initial input station SI receives product production orders.iTom the in-house network, according to the desired mixes, through the communication line 12. This electronic unit A is designed to transfer or write to the memory devices 4 associated with each mould M passing through it corresponding operating information which identifies the products to be formed iti the mould and the corresponding forming operations. Downstream of the station SI there is a station S2, which in the illustrated example is a station for heating the moulds M. This station is also associated with an electronic unit, indicated as a whole by B in Figures 1 and 4, This electronic unit has an architecture similar to that of the unit A, and also comprises a processor 9 with associated memory devices 10, a transmission/reception interface 13, and at least one antenna or the like IS. The electronic unit B can also comprise (at least) a sensor 16 for supplying electrical signals indicating the value of a corresponding physical and/or chemical quantity which is monitored, particularly the temperature to which the moulds M are heated. The processor 9 can then be designed, in particular, to transcribe the detected value of this quantity to the memory devices 4 associated with the moulds M as diey pass through the associated station S2, and/or to transmit this value to the reception unit or units of the control station S16. With reference to Figure 1, a station S3 is provided downstream of the station S2, and comprises a pouring machine which, as shown schematically in Figure 3, pours a predetermined quantity or dose of, for example, plain chocolate, indicated by 17 in Figure 3, into the housings or cells 3 of the moulds M. The station or device S3 is associated with an electronic unit iiidioated by C in P)\|{ures I and 4. Tlie electronic unit C also has a structure similar to that of the imits A and B described above. It therefore comprises a processor 9, with associated memory devices Ifl, transmission-reception interfaces 13, and at least one antenna or tiie like 15. The pouring station or machine S3 can be of a type which can be controlled selectively in a plurality of predetermined modes, in order to form a corresponding plurality of different product types, Its electronic unit C is correspondingly designed to selectively modify the mode of execution of at least one of its operations, on the basis of operatmg information which this unit reads ftom the memory devices 4 associated with each mould M passing through it, or on the basis of information transmitted to it by the electronic unit of the terminal station Si6. The processor 9 of the unit C can conveniently be connected to one or I more sensors, designed to supply electrical signals indicating the values of corresponding physical and/or chemical quantities which are monitored, such as the temperature of the poured material, etc. If necessary, these values can be transcribed by the unit C into the memory devices 4 associated with the various moulds M passing through the station S3, and/or can be transmitted to the terminal station S16. The data transcribed into the memory devices of the mould in this way can be used, for example, to describe the suitability of the product poured into this mould for subsequent applications, for the purpose of forming different types or "flavours" of products. If the pouring machine S3 can selectively pour different types of product, for example plain chocolate, milk chocolate, white chocolate, etc., the associated unit C can comprise an input device 17 which enables an operator to input data identifying the products which are loaded into the station or machine S3 and which can, therefore, be poured into the moulds M. The device 17 is connected to the processor 9. The unit C can also conveniently be designed to transfer data identifying the pouring machine into the memory devices 4 of the moulds M served by it, for the purpo.ses of what is known as process traceability. In the example of the production system shown in Figure 1, a draining station S4 is provided downstream of the pouring station S3, the moulds M being inverted in the station S4, as shown schematically in Figure 3, so as to drain off by gravity the excess of the material 17 which was poured previously After draining, a so-called "shell" 18, formed by the product poured into the station S3, remains on the walls of each housing or cell 3. The station S4 is also associated with an electronic imit, indicated by D in Figures 1 and 4. This unit has u structure similar to that of the electronic units A and B described above. The station S4 is followed by a cooling station 85, in which the shell 18 formed in each housing or cell of the moulds is hardened by reducing the temperature. The station SS is associated with an electronic unit, for example one of the fy\|)e B described above. Downstream of the station S5 there is provided a further pouring station S6, similar to the preceding station S3, and designed to pour a quantity of a materia) 19 in onlor to fimt) a second shell in each housing or cell of the moulds (Figure 3). The station S6 Is associated with an electronic unit C as described above. The station S6 is followed by a further draining station S7 which is similar to the station S4, and which, like S4, is provided with an electronic unit of the type D described above. As a result of the draining which takes place in the station S7, a second shell 20 is formed in each housing or cell of the moukis M on top of the shell 18 formed previously. The material 19 poured in the station S6 can be identical to or different from the material poured in the pouring station S3. Further shells or layers can be formed if necessary in the cells of the moulds, using materials identical to or different fimm those used previously, in further stations which are not shown in Figures 1 and 3. In a subsequent station, indicated by S8, products 21, which can be selectively different from each other, such as hazel nuts or dierries, are deposited in the cells of the moulds M (Figure 3). This station S8 is associated with an electronic unit which can be, for example, of the type D mentioned above. This electronic unit can. In particular, be designed to transcribe into the memory devices 4 of the moulds served by it, or to transnjit directly to the unit S16, information or data identifying the batch containing the products 21 deposited in the individual moulds and the outcome of each individual operation. Thus, for example, if the mould M has not received a hazel nut in each of its cells, the fact that this operation has had a negative outcome will be written to the memory 4 of the mould, and consequently tliis mould will subsequently be 'Rejected". In a subsequent station S9, a filling material 22 is deposited in the housings or cells of the moulds M, this material then being levelled in a subsequent vibration station S10. The stations S9 and S10 are provided with corresponding electronic units, of types C and D respectively. Downstream, there is a further pouring station Sll, which pours a material 23 for forming the top which seals the filled chocolate formed in eadi cell of a mould. The material 23 is, for example, plain chocolate, or another type of chocolate. The pouring station 11 is similar to the preceding ones, and is associated with an electronic unit of type C. The pouring station Sll is followed by a scraping station SI2, which finishos the toptt t of the chocolates by scraping. The station S12 is associated with an electronic unit of typo D. Downstream of the station S12 there is provided a cooling station S13, similar to the station SS described above. The station Si 3 is associated with an electronic unit of type B. In Figures 1 and 3, S14 indicates a station in which the moulds are subjected to vibration for the subsequent demoulding of the products P formed in them. This station is associated with an electronic unit of type D. Finally, this is followed by a demoulding station S15, in which the finished products P are detached fh)m the corresponding housings in the moulds M and are transferred to trays V moved by an auxiliary conveyor 30 towards wrapping and packaging stations such as those described below. Each of the trays V can also conveniently be provided with a corresponding electronic identification device including memory devices, to and from which infonnatbn or data can be (re)vmtten and read by means of an associated antenna or the like. The demoulding station SIS is provided with an electronic unit, of type D for example, designed to transcribe into the memory devices associated with the trays V information or data concerning the modes of packaging the products transferred on these trays. The auxiliary conveyor 30 (Figure 1) then transfers the trays V with the products P to wrapping and packaging stations, in which the products P can be, for example, individually wrapped and then packaged in groups in suitable packages, as shov/n schematically in the lower part of Figure 5. In Figure S, the number 24 indicates the whole of a wrapping and packaging line which comprises a station S25 for collecting and sorting the individual products P from the trays V carried by the conveyor 30. The station S25 is provided with an electronic unit E, similar to the unit described above and also indicated by E. This unit is designed to acquire from the memory devices of the incoming trays V, by means of an associated antenna or the like, the "mapping" of the arrangement of the different types of product P carried by these trays. The station S2S can therefore identify the position of each individual product on each incoming tray V, and can send it selectively to a corresponding wrapping station S26 or S27 or S28 or S29, accordrag to the type (shape and/or "flavour") of the product, using associated conveyor belts 26a-29a. Each of the wrping machines S26-S29 ia provided with at least one corresponding reel 26b-29b of wrapping strip matcrinl which is customized, for example in its material and/or colour and/or design, to match the corresponding type of product. Thus, for example, products having a hazel nut filling can be wrapped with a brown material, while products having a pistachio filling are wrapped with a green material, and so on. In the solution shown by way of example in Figure S, the wrapped products P are then transferred, by a conveyor bell 31, to a packaging station S32, which transfers these products, in uniform groups or arranged according to predetcrtnincd mixes, to packages or boxes 33 carried by a conveyor 34. The machine or vtalioti 32 Is also conveniently provided with an electronic control unit 0 coupled to dovices 3S, such »H vidcocameras and the like, for identifying the incoming wrapped prodlKtA. Tlic olotKroiiio unit 0 also supervises the consitioi of the groups of products according to the predetermined assortments. In an alternative solution, not shown in the drawings, the products P wrapped by the stations S26-S29 can be deposited by these machines, in uniform groups or in predetermined assortments, on additional trays similar to those described above. The.se additional trays are then transferred to a packaging station, similar to the station 32 described above and provided with an electronic unit which, by means of an antenna or the like, can acquire from the memory devices associated with said additional trays the mapping of the positions of the wrapped products conveyed by them. This electronic unit then enables the padcaging station to make up packages with the desired assortments. In Figure 1, S16 indicates a final cancellation station, provided with an electronic unit indicated by E in Figures 1 and 4. This unit is structurally similar to the unit A of the input station SI. The unit £ of the final station SI6 is designed to acquire, from the memory devices 4 of the moulds M passing through it, information or data relating to the characteristics of the products formed in them, together with information on the precise position of each individual cell, and to transfer this information or data to the in-house netwoilc, using a commtinication intcrftce device II and a communication line 12. The data tramiferred in this wy can be stored in the company's archives to ensure the traceability of the products and of the production process, and for the purpose of subsequent use in any later stages of the productbn process, for example the stages of packaging and storage. Alternatively, the final station SI6 could be located at the start or at the end of the packaging line 24 of Figure 5. A further operation for which the unit E of the fmal station S16 can conveniently be designed is that of selectively cancelling, from the memory devices 4 of the moulds M, or of the trays V, or of the aforesaid additional trays if present, all the information which is no bnger necessary, since it relates to the preceding production cycle. In a variant embodiment, the functions'of the validation and cancellation station could be provided by the station SIS of Figure I, and in this case the information relating to the wrapping and packaging operations could be processed by a final station in the wrapping and packaging line. Although the illustration in Figure I shows the initial input station SI and the final validation and cancellation station SI6 as separate and distinct entities, these stations could in fact be made in the form of a single station designed to implement all the dmctionfi described above. Information or data distinguishing each mould M and its associated identification device T are stored indelibly (in other words, on a read-only basis) in the memory devices 4 of the identification device T associated with each mould M. Information or data indicating the number of production cycles and/or specific operations to which the corresponding mould M has been subjected are also stored in these memory devices 4, in an updatable way (in other words, in a readable and rewriteable way). The electronic unit associated with each of the various stations can conveniently be designed to transcribe information or data indicating its own identity into the memory devices 4 of the moulds passing through the station. The electronic units of at least some of the aforesaid stations can also be designed to transcribe, into the memory devices 4 of the moulds M passing through them, information or data indicating the outcome of the operations in which these moulds are to be used in these stations, and/or to transmit said infomiation directly to the control station SI 6. Correspondingly, the electronic units of other stations can conveniently be designed to allow the execution of the operations assigned to them only after they have read, from the memory devices 4 of the moulds M, information indicating the positive outcome of at least one predetemu'ned operation executed by a preceding station, or only after they have received permission fiiom the control station (S16 or other). The electronic unit associated with a station, such as a pouring station, designed to supply a quantity of material from a certain batch to a mould, can conveniently be designed to transcribe into the memory devices associated with this mould the information or data identifying the material supplied and/or its characteristics and/or its batch of origin. The electronic unit associated with one or more stations can be connected to a system for detecting a condition of a mould making it unsuitable for use (for example, a dirty mould condition), and can be designed to transcribe into the memory devices 4 of the mould, in this case, information or data for preventing the use of this mould by the subsequent stations. The system according to the invention allows the implementation of the flexible prodiiclion of a plurality of types of moulded products which differ from each other, For this purpose, the initial input station SI transfers or writes to the memory devices 4 of each mouid M operating information which comprehensively identifies the specific products to be formed in the mould and the corresponding forming operations. On the biisia of this operating information, the subsequent stations are or are not activated, and carry out operations appropriate to the types of product which are to be formed in each mould. Production can therefore be adapted in real time, in a highly flexible way, to the requirements of production and of the producing company, thus overcoming the rigidity and inefRciency of conventional systems of production in successive uniform batches. In the flexible production system described up to this point, each mould can be used to form a specific product, in the sense that the same product is formed on each occasion in all the housings or cells of a mould. In a variant embodiment, at least some of the moulds M can allow the forming of different products, in other words products diversified within a single mould, in predetermined iqsecific areas of the mould. In this case, the input station SI is designed to transcribe into the memoty devices 4 associated with these moulds the infomiation indicating the specific products to be formed in each of the said areas, and the corresponding forming operations. In this way, the flexibility of production can be increased further. Cleariy, provided that the principle of the invention is retdned, the forms of application and in particular the details of construction can be varied videly from what has been described and illustrated purely by way of a non-limiting example, without thereby departing from the scope of the invention, as defined by the appended claims.

System for the flexible production of a plurality of types of moulded food products. particularly chocolate-based products and the like
The present invention relates in a general way to a system for the flexible production of moulded food products of the kind defined in the preamble of claim 1.
Ve-0O5/iO748I diaduses a-sjtem Of this kind for the'production ot human food products such as products moulded from a meat mass, for instance hamburgers. The system involyes the use of a pltirality of types of mould drums, each for the production of a single corresponding kind of products. The mould drums are provided with respective pluralities of through or passing cavities, and a meat mass is passed therethrough under pressure, forming moulded products like hamburgers, which drop firom each mould dnim onto an underlying belt conveyor.
in the technology used for the production of moulded food products, such aa chocolntefl with or without fillings, pralines and the like, various products may frequently have the same structure but differ in the characteristics of one or more of their constituents, For example, a "family" of products of this kind may have a common structure, including a shell formed by a pair of half-shells or wafer sheets, provided with an outer coating and containing a filling and a dried fruit or nut. For such a "family", it is possible to make differentiated products, currently referred to as different "flavours", by varying the filling and/or the associated dried fruit or nut (which may be, for example, an almond, a hazel-nut or a pistachio) and/or by varying the outer coating or a gamish thereon, made for example by applying and/or incorporating chopped meringue and/or hazel-nut or grated coconut (known as "sprinkles").
For the manufacture of such families of products, the production systems used at present require a specific batch production process for each product or "flavour" (using different shaping machines, or using the same machine at different times), these products then being set aside and subsequoitly collected, for example, in order to form "mixed" packages with the requisite combinations of "flavours".

"his production method is not particularly efficient.
}ne object of the present invention is to propose a system for the flexible and substantially imultaneous production of a plurality of types of moulded food products which differ ipom each other, while overcoming the drawbacks of the systems used up to the present ime.
rhese and other objects ane achieved according to the invention widi a system according to ;laim 1.
rhe memory devices associated with the moulds are conveniently of the rewriteable type, uid the system also comprises a final "validation" and cancellation station, which can :electively cancel information or data in the memory devices of the mould passing through it on each occasion.
Further characteristics and advantages of the invention will be made clear by the following detailed description, provided purely by way of non-limiting example, with reference to the appended drawings, in which:
Figure 1 is a schematic perspective view of a flexible production system according to the present invention;

Figure 2 Ls a partial perspective view which shows a portion of a mould used in a flexible production system according to the present invention;
Figure 3 is a schematic representation showing successive operations carried out in a flexible production system according to Figure 1;
Figure 4 is a block diagram showing the architectiu'C of electronic units associated with various stations of a flexible production system according to the invention; and
Figure S is a schematic representation showing a wrapping and packaging system which can be associated with a flexible production system according to the invention, and particularly with the system shown in Figures 1 and 3.
In Figure 1, the number 1 indicates the whole of a system according to the invention for the flexible production of a plurality of types of moulded food products which differ from each other, for example, in their shape and/or their composition.
In the illustrated example of embodiment, the system 1 comprises a conveyor 2 for conveying in sequence a plurality of moulds M along an essentially loop-shaped production path, on which is located a plurality of stations or devices Si-SI 6, each designed to execute at least one corresponding operation.
With reference to Figure 2, in the illustrated example each mould M has a corresponding plurality of housings or cells 3 for forming corresponding moulded products such &a filled chocolates and the like.
Each mould M carries a corresponding electronic identificatbn device, indicated ns a whole by T in Figure 2. This device, which may be what is known as an RFID, includes integrated electronic memory devices 4, from and to which information or data can be road and written, and if necessary rewritten, without contact, by means of an associated antenna or the like 5. The identification device T associated with each mould M can also comprise a microprocessor 6 and if necessary one or more sensors 7 for supplying electrical signals indicating the value of a corresponding physical and/or chemical quantity which is monitored, such as temperature or nooisture content, this value being writeable to the

associated memory devices 4 and/or being directly transmitted to the electronic unit of one or more stations SI-S16, which are described below with reference to Figure 4.
The identificaHon device T in the drawing is shown in a position adjacent to lite mould M, but it could also be "embedded" or otherwise incorporated into the mould itself.
An interface circuit 8 can be interposed between the antenna S and the microprocessor 6, if the latter is present.
The example illustrated in Figure I shows sixteen stations SI-SI 6, each of which is associated with a correonding electronic unit which, as described more fully below, includes a processor with associated memory devices and at least one antenna or the like. This processor is designed to read and/or write inforaiation or data from or to the memory devices 4 of each mould M passing through the station.
In particular, the station SI is an initial input station. It is associated with an electronic unit indicated by A in Figures 1 and 4. This unit comprises a processor 9 with associated memory devices 10. The processor 9 is connected to a communications interface device 11 connected by a communication line 12 to an in-house communication networic.

The microprocessor 9 is connected to at

(east one antenna or the like 15 by means of

transmission interftce devices indicated as a whole by 13.
The electronic unit A of the initial input station SI receives product production orders.iTom the in-house network, according to the desired mixes, through the communication line 12. This electronic unit A is designed to transfer or write to the memory devices 4 associated with each mould M passing through it corresponding operating information which identifies the products to be formed iti the mould and the corresponding forming operations.
Downstream of the station SI there is a station S2, which in the illustrated example is a station for heating the moulds M. This station is also associated with an electronic unit,

indicated as a whole by B in Figures 1 and 4, This electronic unit has an architecture similar to that of the unit A, and also comprises a processor 9 with associated memory devices 10, a transmission/reception interface 13, and at least one antenna or the like IS. The electronic unit B can also comprise (at least) a sensor 16 for supplying electrical signals indicating the value of a corresponding physical and/or chemical quantity which is monitored, particularly the temperature to which the moulds M are heated. The processor 9 can then be designed, in particular, to transcribe the detected value of this quantity to the memory devices 4 associated with the moulds M as diey pass through the associated station S2, and/or to transmit this value to the reception unit or units of the control station S16.
With reference to Figure 1, a station S3 is provided downstream of the station S2, and comprises a pouring machine which, as shown schematically in Figure 3, pours a predetermined quantity or dose of, for example, plain chocolate, indicated by 17 in Figure 3, into the housings or cells 3 of the moulds M.
The station or device S3 is associated with an electronic unit iiidioated by C in P)|{ures I and 4. Tlie electronic unit C also has a structure similar to that of the imits A and B described above. It therefore comprises a processor 9, with associated memory devices Ifl, transmission-reception interfaces 13, and at least one antenna or tiie like 15.
The pouring station or machine S3 can be of a type which can be controlled selectively in a plurality of predetermined modes, in order to form a corresponding plurality of different product types, Its electronic unit C is correspondingly designed to selectively modify the mode of execution of at least one of its operations, on the basis of operatmg information which this unit reads ftom the memory devices 4 associated with each mould M passing through it, or on the basis of information transmitted to it by the electronic unit of the
terminal station Si6. The processor 9 of the unit C can conveniently be connected to one or
I
more sensors, designed to supply electrical signals indicating the values of corresponding physical and/or chemical quantities which are monitored, such as the temperature of the poured material, etc. If necessary, these values can be transcribed by the unit C into the memory devices 4 associated with the various moulds M passing through the station S3,

and/or can be transmitted to the terminal station S16. The data transcribed into the memory devices of the mould in this way can be used, for example, to describe the suitability of the product poured into this mould for subsequent applications, for the purpose of forming different types or "flavours" of products.
If the pouring machine S3 can selectively pour different types of product, for example plain chocolate, milk chocolate, white chocolate, etc., the associated unit C can comprise an input device 17 which enables an operator to input data identifying the products which are loaded into the station or machine S3 and which can, therefore, be poured into the moulds M. The device 17 is connected to the processor 9.
The unit C can also conveniently be designed to transfer data identifying the pouring machine into the memory devices 4 of the moulds M served by it, for the purpo.ses of what is known as process traceability.
In the example of the production system shown in Figure 1, a draining station S4 is provided downstream of the pouring station S3, the moulds M being inverted in the station S4, as shown schematically in Figure 3, so as to drain off by gravity the excess of the material 17 which was poured previously After draining, a so-called "shell" 18, formed by the product poured into the station S3, remains on the walls of each housing or cell 3.
The station S4 is also associated with an electronic imit, indicated by D in Figures 1 and 4. This unit has u structure similar to that of the electronic units A and B described above.
The station S4 is followed by a cooling station 85, in which the shell 18 formed in each housing or cell of the moulds is hardened by reducing the temperature.
The station SS is associated with an electronic unit, for example one of the fy|)e B described above.
Downstream of the station S5 there is provided a further pouring station S6, similar to the preceding station S3, and designed to pour a quantity of a materia) 19 in onlor to fimt) a

second shell in each housing or cell of the moulds (Figure 3). The station S6 Is associated with an electronic unit C as described above.
The station S6 is followed by a further draining station S7 which is similar to the station S4, and which, like S4, is provided with an electronic unit of the type D described above. As a result of the draining which takes place in the station S7, a second shell 20 is formed in each housing or cell of the moukis M on top of the shell 18 formed previously.
The material 19 poured in the station S6 can be identical to or different from the material poured in the pouring station S3.
Further shells or layers can be formed if necessary in the cells of the moulds, using materials identical to or different fimm those used previously, in further stations which are not shown in Figures 1 and 3.
In a subsequent station, indicated by S8, products 21, which can be selectively different from each other, such as hazel nuts or dierries, are deposited in the cells of the moulds M (Figure 3). This station S8 is associated with an electronic unit which can be, for example, of the type D mentioned above. This electronic unit can. In particular, be designed to transcribe into the memory devices 4 of the moulds served by it, or to transnjit directly to the unit S16, information or data identifying the batch containing the products 21 deposited in the individual moulds and the outcome of each individual operation. Thus, for example, if the mould M has not received a hazel nut in each of its cells, the fact that this operation has had a negative outcome will be written to the memory 4 of the mould, and consequently tliis mould will subsequently be 'Rejected".
In a subsequent station S9, a filling material 22 is deposited in the housings or cells of the moulds M, this material then being levelled in a subsequent vibration station S10.
The stations S9 and S10 are provided with corresponding electronic units, of types C and D respectively.

Downstream, there is a further pouring station Sll, which pours a material 23 for forming the top which seals the filled chocolate formed in eadi cell of a mould. The material 23 is, for example, plain chocolate, or another type of chocolate. The pouring station 11 is similar to the preceding ones, and is associated with an electronic unit of type C.
The pouring station Sll is followed by a scraping station SI2, which finishos the toptt t of the chocolates by scraping. The station S12 is associated with an electronic unit of typo D.
Downstream of the station S12 there is provided a cooling station S13, similar to the station SS described above. The station Si 3 is associated with an electronic unit of type B.
In Figures 1 and 3, S14 indicates a station in which the moulds are subjected to vibration for the subsequent demoulding of the products P formed in them. This station is associated with an electronic unit of type D.
Finally, this is followed by a demoulding station S15, in which the finished products P are detached fh)m the corresponding housings in the moulds M and are transferred to trays V moved by an auxiliary conveyor 30 towards wrapping and packaging stations such as those described below.
Each of the trays V can also conveniently be provided with a corresponding electronic identification device including memory devices, to and from which infonnatbn or data can be (re)vmtten and read by means of an associated antenna or the like. The demoulding station SIS is provided with an electronic unit, of type D for example, designed to transcribe into the memory devices associated with the trays V information or data concerning the modes of packaging the products transferred on these trays.
The auxiliary conveyor 30 (Figure 1) then transfers the trays V with the products P to wrapping and packaging stations, in which the products P can be, for example, individually wrapped and then packaged in groups in suitable packages, as shov/n schematically in the lower part of Figure 5.

In Figure S, the number 24 indicates the whole of a wrapping and packaging line which comprises a station S25 for collecting and sorting the individual products P from the trays V carried by the conveyor 30. The station S25 is provided with an electronic unit E, similar to the unit described above and also indicated by E. This unit is designed to acquire from the memory devices of the incoming trays V, by means of an associated antenna or the like, the "mapping" of the arrangement of the different types of product P carried by these trays. The station S2S can therefore identify the position of each individual product on each incoming tray V, and can send it selectively to a corresponding wrapping station S26 or S27 or S28 or S29, accordrag to the type (shape and/or "flavour") of the product, using associated conveyor belts 26a-29a. Each of the wrping machines S26-S29 ia provided with at least one corresponding reel 26b-29b of wrapping strip matcrinl which is customized, for example in its material and/or colour and/or design, to match the corresponding type of product. Thus, for example, products having a hazel nut filling can be wrapped with a brown material, while products having a pistachio filling are wrapped with a green material, and so on. In the solution shown by way of example in Figure S, the wrapped products P are then transferred, by a conveyor bell 31, to a packaging station S32, which transfers these products, in uniform groups or arranged according to predetcrtnincd mixes, to packages or boxes 33 carried by a conveyor 34. The machine or vtalioti 32 Is also conveniently provided with an electronic control unit 0 coupled to dovices 3S, such »H vidcocameras and the like, for identifying the incoming wrapped prodlKtA. Tlic olotKroiiio unit 0 also supervises the consitioi of the groups of products according to the predetermined assortments.
In an alternative solution, not shown in the drawings, the products P wrapped by the stations S26-S29 can be deposited by these machines, in uniform groups or in predetermined assortments, on additional trays similar to those described above. The.se additional trays are then transferred to a packaging station, similar to the station 32 described above and provided with an electronic unit which, by means of an antenna or the like, can acquire from the memory devices associated with said additional trays the mapping of the positions of the wrapped products conveyed by them. This electronic unit then enables the padcaging station to make up packages with the desired assortments.

In Figure 1, S16 indicates a final cancellation station, provided with an electronic unit indicated by E in Figures 1 and 4. This unit is structurally similar to the unit A of the input station SI. The unit £ of the final station SI6 is designed to acquire, from the memory devices 4 of the moulds M passing through it, information or data relating to the characteristics of the products formed in them, together with information on the precise position of each individual cell, and to transfer this information or data to the in-house netwoilc, using a commtinication intcrftce device II and a communication line 12. The data tramiferred in this wy can be stored in the company's archives to ensure the traceability of the products and of the production process, and for the purpose of subsequent use in any later stages of the productbn process, for example the stages of packaging and storage.
Alternatively, the final station SI6 could be located at the start or at the end of the packaging line 24 of Figure 5.
A further operation for which the unit E of the fmal station S16 can conveniently be designed is that of selectively cancelling, from the memory devices 4 of the moulds M, or of the trays V, or of the aforesaid additional trays if present, all the information which is no bnger necessary, since it relates to the preceding production cycle.
In a variant embodiment, the functions'of the validation and cancellation station could be provided by the station SIS of Figure I, and in this case the information relating to the wrapping and packaging operations could be processed by a final station in the wrapping and packaging line.
Although the illustration in Figure I shows the initial input station SI and the final validation and cancellation station SI6 as separate and distinct entities, these stations could in fact be made in the form of a single station designed to implement all the dmctionfi described above.

Information or data distinguishing each mould M and its associated identification device T are stored indelibly (in other words, on a read-only basis) in the memory devices 4 of the identification device T associated with each mould M.
Information or data indicating the number of production cycles and/or specific operations to which the corresponding mould M has been subjected are also stored in these memory devices 4, in an updatable way (in other words, in a readable and rewriteable way).
The electronic unit associated with each of the various stations can conveniently be designed to transcribe information or data indicating its own identity into the memory devices 4 of the moulds passing through the station.
The electronic units of at least some of the aforesaid stations can also be designed to transcribe, into the memory devices 4 of the moulds M passing through them, information or data indicating the outcome of the operations in which these moulds are to be used in these stations, and/or to transmit said infomiation directly to the control station SI 6.
Correspondingly, the electronic units of other stations can conveniently be designed to allow the execution of the operations assigned to them only after they have read, from the memory devices 4 of the moulds M, information indicating the positive outcome of at least one predetemu'ned operation executed by a preceding station, or only after they have received permission fiiom the control station (S16 or other).
The electronic unit associated with a station, such as a pouring station, designed to supply a quantity of material from a certain batch to a mould, can conveniently be designed to transcribe into the memory devices associated with this mould the information or data identifying the material supplied and/or its characteristics and/or its batch of origin.
The electronic unit associated with one or more stations can be connected to a system for detecting a condition of a mould making it unsuitable for use (for example, a dirty mould condition), and can be designed to transcribe into the memory devices 4 of the mould, in

this case, information or data for preventing the use of this mould by the subsequent stations.
The system according to the invention allows the implementation of the flexible prodiiclion of a plurality of types of moulded products which differ from each other,
For this purpose, the initial input station SI transfers or writes to the memory devices 4 of each mouid M operating information which comprehensively identifies the specific products to be formed in the mould and the corresponding forming operations. On the biisia of this operating information, the subsequent stations are or are not activated, and carry out operations appropriate to the types of product which are to be formed in each mould.
Production can therefore be adapted in real time, in a highly flexible way, to the requirements of production and of the producing company, thus overcoming the rigidity and inefRciency of conventional systems of production in successive uniform batches.
In the flexible production system described up to this point, each mould can be used to form a specific product, in the sense that the same product is formed on each occasion in all the housings or cells of a mould.
In a variant embodiment, at least some of the moulds M can allow the forming of different products, in other words products diversified within a single mould, in predetermined iqsecific areas of the mould. In this case, the input station SI is designed to transcribe into the memoty devices 4 associated with these moulds the infomiation indicating the specific products to be formed in each of the said areas, and the corresponding forming operations.
In this way, the flexibility of production can be increased further.
Cleariy, provided that the principle of the invention is retdned, the forms of application and in particular the details of construction can be varied videly from what has been described and illustrated purely by way of a non-limiting example, without thereby departing from the scope of the invention, as defined by the appended claims.
