Full Text	This invention relates to a feeding device for polybagging machine. The polybagging machine are as such known in the prior art for producing polybagging having packets arranged therein. The feeding device of such machines comprises a belt conveyor to receive the packets from the discharge end of the packing machine and convey the same to a stack making station of polybagging machine. When the stack of the packet is formed on the first belt conveyor the second belt conveyor starts rotating for conveying the stack packets to the stack push station and wherein the stack of packets is being pushed by a pusher operated by a pneumatic cylinder into the polybagging machine. There are certain disadvantages associated with the conventional feeding device. One of the main disadvantage is that the stack of packets is conveyed on a belt conveyor due to friction, but the light weight packets gets disturbed during the conveying. Also some of the light weight packets are of the irregular shapes like biscuit pouches and the stack get disturbed because of its interference with guides provided on the conveyor belt. Therefore the main object of this invention is to provide an improved feeding device for use with polybagging machines which obviates the disadvantages associated with the prior art. Another object of this invention is to propose a feeding device for polybagging machine having means to convey the stack of packets in an undisturbed position. Still another object of this invention is to propose a polybagging machine wherein the use of the second conveyor belt has been eliminated. Thus the operation and speed of the machine has been increased. According to this invention there is provided a feeding device for polybagging machine comprising a first conveyor belt provided for conveying the packets (P) received from the packaging machine to a stack making station of a polybagging machine, a stack pusher being provided to push the stack onto a base plate characterized in that said base plate having a plurality of channels being provided for guiding the conveyance of the stack of packet to the feeding station (F), finger pusher assembly being provided below said base plate such that to convey the stack of packet (S) to the feeding station, wherein said finger pusher assembly comprises a plurality of finger pusher secured with a first bracket, said bracket is secured pivotly with a second bracket, adapted to move in the horizontal and vertical direction by a pneumatic cylinder, and said second bracket is mounted on a pair of guides provided to guide the vertical movement of said bracket. In accordance with this invention a feeding device for use in polybagging machine has a belt conveyor for conveying the packets to the stack formation station of the bagging machine. A stack pusher is provided at the right angle to the belt conveyor for pushing the stack onto a base plate and which is being conveyed to the feeding station of the bagging machine. Specifically in accordance with this invention the base plate having plurality of channels and a finger pusher assembly provided therewith is provided to convey the stack instead of the conveyor belt provided for conveying the stack of the packets in the conventional machine. A feeding device for use in polybagging machine according to a preferred embodiment is herein described and illustrated in the accompanying drawings wherein s- Fig. 1 shows plan view of the feeding assembly of the known art. Fig. 2 shows the plan view of the feeding assembly of the present invention. Fig. 3 shows the side view of the finger pusher and Fig. 4 shows the top view of the finger pusher. Referring to the drawings particular fig. 1 the conventional feeding device has a conveyor belt B for receiving and conveying the packets P received from the packaging machine. A pusher P adapted to be operated by a pneumatic cylinder C is provided over the conveyor belt B such as to push the stack of the packets onto a second belt B1 which convey stack of the packets S to the feeding station F of the bagging machine. Reference is now made to fig. 2 the feeding device according to this invention has a conveyor belt 1 for receiving and conveying the packets P to the stack making station of the machine. A stopper 3 is provided to stop the packets P at the stack making station. A pusher 2 adapted to be operated by a pneumatic cylinder 4 in a conventional manner is provided over the conveyor belt 1 such as to push the stack of packets onto a base plate 5.

There are certain disadvantages associated with the conventional feeding device.
One of the main disadvantage is that the stack of packets is conveyed on a belt conveyor due to friction, but the light weight packets gets disturbed
during the conveying. Also some of the light weight packets are of the irregular shapes like biscuit pouches
and the stack get disturbed because of its interference with guides provided on the conveyor belt.
Therefore the main object of this invention is to provide an improved feeding device for use with polybagging machines which obviates the disadvantages associated with the prior art.
Another object of this invention is to propose a feeding device for polybagging machine having means to convey the stack of packets in an undisturbed position.
