Vacuum gripper
Slim lightweight layer gripper for cobots
With the new weight-reduced layer gripper from Schmalz, cobots can also palletize lighter workpiece layers.
Depending on the model and manufacturer, lightweight robots have a load capacity of up to 25 kilograms. In order to use them for layer-by-layer palletizing and depalletizing, J. Schmalz has given its layer grippers a diet. The result is the weight-reduced ZLW lightweight layer gripper, which can lift up to 20 kilograms and weighs only between four and 7.5 kilograms, depending on its size. This leaves the robot with enough payload for the actual handling task.
Lightweight gripper
The ZLW extends the SPZ series of layer gripping systems downwards and can grip several open, hollow or closed objects such as jars, 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 matched to each other and to the task.
The vacuum generator is also dimensioned so that it does not require more power than is necessary for process reliability. But this is not the only thing that increases the efficiency of the handling process: the new layer gripper also indirectly helps to keep theCO2 footprint low: Smaller robots require less power and therefore support sustainable automation - for example during feeding in production, automated warehousing or end-of-line palletizing.
Schmalz has deliberately kept the design slim: The sealing element is fitted with either individual plug-in suction cups or a sealing foam. A frame connects these to the honeycomb plate, on which a pressure relief valve, the VSi vacuum switch and the flange are mounted. The vacuum generator stands separately.
