Robotic Pallet Cell Configurations

Robotic palletizing/depalletizing applications are on the rise as manufacturers look to increase productivity and reduce labor by automating portions or even entire packaging lines. In the simplest configuration, a robotic pallet cell consists of one line in/one line out, one robot, loading or unloading one pallet at a time. But depending on the application, pallet cells can be configured a number of ways, incorporating multiple lines and loading or unloading multiple pallets using one robot. This application note describes the various ways one can configure ESS Technologies, Inc. robotic pallet cell equipment to meet any packaging configuration.

System Description

ESS Technologies, Inc. Mini Cell Palletizer series incorporates a FANUC robot to create single pallet, dual pallet, and multiple pallet configurations. The robot lifts the packed and sealed case from the infeed conveyor(s) which may be inline or at 90°. Case grips, either suction cups or mechanical grips, are specially designed for each application. The case is then placed on the pallet in the specified arrangement. Full pallets may be removed automatically using pallet discharge conveyors, manually or by using self-guided vehicles. Empty pallets can be set in place manually or the system can be automated by incorporating a pallet magazine and pallet dispenser. The diagrams below illustrate several configurations of robotic palletizing systems. Any configuration can be custom-engineered by ESS’s design team to meet any palletizing applications. Depending on the payload and reach requirements of the system, a number of FANUC robots may be specified with the robotic pallet cell.

Pallet Cell Diagrams

1 In / 1 Out Robotic Pallet Cell
The most basic robotic pallet cell configuration uses one robot to move cases of product from one conveyor infeed to one pallet. The empty pallet may be placed using an optional pallet dispenser. Full pallets are moved out using either a forklift or a self guided vehicle.

1 In / 2 Out Robotic Pallet Cell
One in x 2 out robotic pallet cells provide room for an additional pallet. The robot loads the first pallet completely and then begins loading the second pallet while the full pallet is removed and replaced with an empty pallet. This configuration eliminates the need for expensive accumulating equipment without stopping the production line.

Multi-Infeed/ Multi-Pallet Robotic Pallet Cells
	Robotic pallet cells configured with two or more infeeds are ideal for packaging lines that handle multiple products. The system can load pallets containing one product per pallet, or multiple products can be palletized together. Optional deck sheet and tier sheet dispensers and pallet stretch wrappers can be integrated into the line to create a fully automated palletizing system.
