Bulk Container Depalletizers provide an efficient means to sort or "single file" containers from bulk layered pallets onto a conveyor or conveying system for use in high speed automated packaging systems. There are essentially two types of depalletizer systems: "High Level" and "Low Level." This refers to the height at which the pallet is positioned during the unloading process.

A High Level Depalletizer lifts a full pallet to the desired height to permit the container positioner to sweep the product into an accumulation table. The machine removes separators, top frames, tier sheets etc automatically. Once a layer from the pallet has been transferred to the accumulation table, the machine raises the pallet to the next layer. When the pallet is empty, it is discharged & stacked and the next pallet is introduced from the magazine.

A Low Level Depalletizer remains at floor level throughout the unloading process. An important consideration for plant design is that the depalletized containers can exit the machine at any elevation required to suit production needs. The machine automatically removes each layer from the pallet and raises/lowers the pallet to the required level to transfer containers onto the accumulation table, one tier at a time. As with the High Level system, the machine automatically removes separators, top frames, tier sheets, discharges the empty pallet and introduces the next pallet from the magazine automatically, or permits an operator to manually position a pallet (semi-automatic operation).

There are many considerations we must take into account when specifying depalletization machinery for an application, used or new. A good depalletizer system should be configured to suit the plant layout, both with respect to feeding and discharge. The construction, design, and general requirements of depalletizer systems vary greatly by industry, including the Food, Beverage, Pharmaceutical, Nutraceutical, Consumer Products, and Chemical Industries. Types of Containers that can be utilized in these systems vary greatly: Plastic Bottles, Glass Bottles, Glass Jars, Plastic Jars, Metal Cans, Metal Bottles, have been depalletized at rates exceeding 1200 units per minute.

In addition, depalletizer speed demands range from under 100 containers per minute to speeds in excess of 1200 containers per minute. In many cases certain original equipment manufacturers' standard designs may be advantageous for certain types of applications. In all cases the design standards of the depalletizer equipment, material of construction, method, and capacity much match the application's requirements.

The following considerations should be addressed when planning a depalletizer system design:

• Container Specifications — this includes material of construction (i.e.: Glass, HDPE Plastic, PET Plastic*), dimensional drawings, etc. Many times this is easiest accomplished if a customer elects to send a sample of each container in question to our attention.
• Speed Requirements — average and maximum desired rate at which bottles or containers must be depalletized. High Level systems typically operate at greater speeds than Low Level systems.
• Production Requirements — what is the product to be filled or packaged? What specifications must the equipment meet (i.e. GMP, FDA, Explosion Proof)? What type of system will the unit be feeding? Are there any other necessary functions that may be easiest or most economically performed as part of the depalletizing system itself (i.e.: Lowerator, Lowerator/Rinser)?

At any given time, BPDM typically has a variety of depalletizers, pallet elevators and related equipment in our used, rebuilt and/or reconditioned inventory. We can also furnish new equipment or produce a system incorporating custom design features. Please contact us with your requirements if you would like to discuss your applications.
