Abstract

The invention relates to a sorting system (100) for a machine tool for separating parts, in particular a laser cutting machine (200), having a gripper (110) that can be moved over a workpiece region (30) and is configured to receive cut parts (10) from the workpiece region (30), and an intermediate store (120) that can be moved over the workpiece region (30) and is configured to receive cut parts (10) from the gripper (110) and to unload the cut parts (10) into a store (40).

First claim

The invention claimed is:

1. A sorting system for a laser cutting machine, the sorting system having a controller for controlling the sorting system and having a gripper that can be moved over a workpiece region and is configured to receive cut parts from the workpiece region, and an intermediate store that can be moved over the workpiece region and is configured to receive cut parts from the gripper and to unload the cut parts into a store, wherein the gripper and the intermediate store are arranged on a carrier element that can be moved on rails in a first direction, characterized that the gripper and the intermediate store are arranged to be movable on the carrier element independently of one another in a second direction, wherein the first and the second direction lie in one plane of the workpiece region, the plane of the workpiece region being a plane in which the workpiece region lies or parallel thereto, and that the gripper and the intermediate store are each arranged on a telescopic arm that can be moved in the direction perpendicular to the plane of the workpiece region.

2. The sorting system for the laser cutting machine tool according to claim 1 , characterized in that the gripper and the intermediate store are arranged on the telescopic arm by means of a releasable coupling.

3. The sorting system for the laser cutting machine according to claim 1 , characterized in that the intermediate store has a sliding device that is configured to push cut parts out of the intermediate store.

4. The sorting system for the laser cutting machine according to claim 1 , characterized in that the intermediate store has a contact surface for the cut parts formed from a plurality of tines.

5. A laser cutting machine, configured for separating cut parts from a workpiece having a sorting system according to claim 1 .

6. The laser cutting machine according to claim 5 , characterized in that a changing station for a changing table is provided and in that the gripper and the intermediate store of the sorting system are arranged on the changing station so as to be movable over the changing table, the changing table corresponding to the workpiece region.

7. A method for sorting cut parts from a workpiece region of a laser cutting machine, by means of a sorting system according to claim 1 , the method having the steps of
Moving the gripper to receive a cut part;
Depositing the cut part in the intermediate store;
Moving the intermediate store to the store and unloading the intermediate store.

8. The method for sorting cut parts according to claim 7 , characterized in that the moving and the depositing steps are repeated until the intermediate store is filled or all cut parts have been received.

9. The method for sorting cut parts according to claim 7 , characterized that the intermediate store follows the movement of the gripper.
