ABSTRACT:
An envelope handling system for removing envelopes from an upper level conveyor, placing them in stacks on a lower level bucket conveyor, removing the stacks from the bucket, conveyor and side-loading them into cartons, sealing the cartons, conveying the cartons to a packing area, and forming the cartons into a horizontal column for placement into shipping containers. The system includes a spider feeder for removing the envelopes from an upper level conveyor and discharging them downwardly in a vertical direction, pivoting bottom fingers for receiving envelopes from the feeder and collecting them into a stack, hold back fingers for intercepting envelopes in a second stack above the bottom fingers, and transfer fingers for compressing a stack collected on the bottom fingers and urging the bottom fingers downwardly to place the stack onto the conveyor. A reciprocating ram urges a stack sidewardly from a bucket, a chute and pivoting gate members direct a stack into a set-up carton and compress the stack as it passes therethrough. Reciprocating tucker bars close upstream end flaps of the carton. A helical conveyor channel receives cartons from a sealing machine, orients the cartons onto a horizontal surface. A reciprocating plate urges the cartons along a channel and a reciprocating platen urges the cartons sidewardly to form the horizontal column.
