Ice cream sandwich collating apparatus

Abstract

Apparatus for collating ice cream sandwiches for packaging, includes a flat dead plate; an endless belt conveyor for conveying the articles in a first direction onto the dead plate; a stop and guide for limiting movement of the ice cream sandwiches on the dead plate to a first position; an optical detector which detects when a predetermined number of the ice cream sandwiches have been conveyed to the first position on the dead plate against the stop; an air cylinder mounted above the dead plate; a sliding plate movable along the air cylinder; a pivot bracket secured to the sliding plate; an L-shaped pusher member pivotally mounted on the bracket for pushing the ice cream sandwiches from the first position to a second position in a second direction substantially transverse to the first direction so as to collate the ice cream sandwiches; a cam track fixed to the frame; a roller mounted on the pivot rod of the pusher member and which rides along the cam track from the first position to the second position so as to maintain the pusher plate in a pushing position and which rides above the cam track during the return of the pusher member to pivot the same above subsequent ice cream sandwiches conveyed onto the dead plate so as to permit conveyance of the subsequent ice cream sandwiches onto the dead plate during movement of the pusher member from the end position to the start position.
