ABSTRACT:
A product gripper mechanism, particularly for gripping a plurality of products in a product group, such as bakery products, for transfer to and loading into a shipping basket or tray. The gripper is constructed of a material, such as rigid PVC tubing, which is easily obtainable, lightweight and of substantial strength. The gripper frame includes spaced-apart lateral supports, which carry a plurality of adjustably positionable cross members carrying suction devices. The suction devices are adjustably positionable on the cross members, and may easily be added to or removed from the cross members. The assembly of the tubing elements is such as to accommodate rapid disassembly and reassembly, in order to reconfigure the gripper for different product types. The gripper has pivoting end flaps of L-shaped configuration provided with thin, flexible, inwardly projecting bottom plates. The bottom plates are arranged, when the end flaps are closed, to slide underneath end portions of the product items to help support the product when the gripper is accelerated upwardly to transfer the packages from the pick up location to the load station.
