Abstract

Stacking equipment for stacking products such as boxes or cartons in lay-flat form onto pallets, comprising a receiving conveyor (1) means (6, 7, 8) thereon for collecting a batch of products together in predetermined disposition, and a push plate (11) for transferring an assembled batch of products onto a main support bed (15). The bed (15) raises the batch of products onto retractable temporary support fingers (17) and then returns to receive the next succeeding batch. The batches are stacked successively and finally supported on a pallet which is elevated on bed (15) to support the finished stack which is then discharged from the bed. Also provided are a pallet dispenser (30) adjacent the support bed (15) and a tiesheet dispenser (20) to place an individual tie sheet on the top of each successive batch prior to stacking.
