Depending on the model and manufacturer, lightweight robots have a payload of up to 25 kilograms. In order to use them for palletizing and depalletizing in layers, J. Schmalz GmbH has given its layer grippers a diet. The result is the weight-reduced lightweight layer gripper ZLW, which lifts up to 20 kilograms and – depending on the size – only weighs between four and 7.5 kilograms. This leaves the robot with enough payload for the actual handling task.

The ZLW expands the series of SPZ layer gripping systems downwards and can grip several open, hollow or closed objects such as glasses, cans or cardboard boxes with different dimensions at the same time. It compensates for height differences in the workpiece position with an optionally available spring-loaded flange. In addition, Schmalz configures the lightweight gripper individually: The user receives an efficient complete system with components that are tailored to each other and to the task. The vacuum generator is also dimensioned in such a way that it does not require more power than is required for process reliability.

The sealing element is equipped with either individual plug-in suction cups or a sealing foam. A frame connects these to the honeycomb panel on which a pressure relief valve, the VSi vacuum switch and the flange are mounted. The vacuum generator is separate.
