Abstract
A device and a method for separating sheet material is provided. The separation of sheet material is not effected statically, but a suitable pick-up position and/or a suitable pick-up mechanism is selected for each sheet material piece, for example in dependence on the quality of a surface of the sheet material piece to be picked up, in order to pick up the sheet material piece from the sheet material stack and remove it from the same.
Claims8
A device for separating sheet material, with a sheet material pick-up which is configured to pick up a single sheet material piece from a sheet material stack which comprises several sheet material pieces, and with an actuator which is configured to shift the sheet material pick-up, wherein the device furthermore comprises:
- an image acquisition unit which is configured to capture an image of a surface of the single sheet material piece and to provide image data;
- and
- an evaluation unit downstream of the image acquisition unit, which is configured to receive the image data and to provide an evaluation result in dependence on an evaluation of the image data;
- wherein the device is configured to determine a pick-up position in dependence on the evaluation result and to position the sheet material pick-up at the pick-up position, in order to pick up the single sheet material piece at the pick up position and remove it from the sheet material stack;
- and
- wherein the evaluation unit is configured to determine adhesion properties of a surface of the single sheet material piece with reference to the image data and to provide the evaluation result in dependence on the adhesion properties.
