Sentry High Level Bulk Depalletizer with Accumulation Table and Discharge Conveyors

The Sentry Bulk Depalletizer is designed to handle bulk loads of empty glass, PET or aluminum containers on wooden or plastic pallets, and to transfer them one at a time to a conveyor belt for transportation to the production room.

​The speed of the machines will vary depending on the type of product. However, a single Sentry Bulk Depalletizer will provide a continuous supply of products up to 1000 bottles per minute or 2200 cans per minute to PET Bottle Fillers.


The hoisting platform is raised and lowered by a 4000lb capacity servo drive, which elevates it and lowers it using heavy-duty formed steel and crosses bracing.

Full pallet conveyors are constructed from heavy-gauge sheet metal with #80 pitch roller chains.

The hoist conveyor is driven by a constant speed gear motor driven by a Eurodrive constant speed sensor which automatically positions the pallet inside the hoist chamber prior to depalletizing.
