Abstract

A machine tool for processing workpieces includes a processing device from which processed products to be discharged can be produced from a workpiece; and a discharge device including a discharge flap that can be pivoted into a discharge position inclined downwards relative to a horizontal position in order to discharge processed products and which defines a discharge direction in the discharge position, the discharge flap comprising a part support disposed along the upper side of the discharge flap along which the processed products move during discharge in the discharge direction, where the part support has at least two support regions which extend in the discharge direction and which are configured to accommodate different types of processed products.

Claims

1. A workpiece processing method, comprising:

positioning a workpiece relative to a processing device to undergo a workpiece processing operation;

producing a processed product as a result of the workpiece processing operation, the processed product being of a first type or of a second type that is different from the first type; and

discharging the processed product using a discharge device that comprises a discharge flap, the discharge flap being pivotal into a discharge position inclined downward relative to a horizontal position and defining a discharge direction, and the discharge flap comprising a part support on an upper side thereof,

wherein the part support comprises first and second support regions that extend in the discharge direction;

wherein the first support region comprises first properties configured to support the processed product being of the first type such that the first support region is configured to move the processed product being of the first type in the discharge direction;

wherein the second support region comprises second properties that are different from the first properties of the first support region and that are configured to support the processed product being of the second type such that the second support region is configured to move the processed product being of the second type in the discharge direction;

wherein the workpiece, undergoing the workpiece processing operation, is positioned in a manner such that;

the processed product being of the first type resulting from the workpiece processing operation is arranged on the first support region when the workpiece processing operation is finished, or

the processed product being of the second type resulting from the workpiece processing operation is arranged on the second support region when the workpiece processing operation is finished; and

wherein the first support region is constructed of a support brush comprising one or both of first bristles and first bristle bundles and the second support region is constructed of a support brush comprising one or both of second bristles and second bristle bundles, the one or both of the first bristles and the first bristle bundles having a different angle of orientation with respect to the discharge direction than the one or both of the second bristles and the second bristle bundles.

2. The workpiece processing method according to claim 1, wherein the first support region has different surface properties than the second support region.

3. The workpiece processing method according to claim 1, wherein one of the first and second support regions protrudes towards the processed product to a greater extent than the other of the first and second support regions.

4. The workpiece processing method according to claim 1, wherein the one or both of the first bristles and the first bristle bundles further have one or more of a different material type, a different rigidity, and a different hardness than the one or both of the second bristles and the second bristle bundles.

5. The workpiece processing method according to claim 1, wherein the first support region has a different material composition than the second support region.

6. The workpiece processing method according to claim 1, wherein the first and second support regions comprise support elements, at least one support element of the first support region having a different construction type than at least one support element of the second support region.

7. The workpiece processing method according to claim 1, wherein the first and second support regions comprise support elements, the support elements of the first support region being arranged in a first pattern along the first support region and the support elements of the second support region being arranged in a second pattern along the second support region, and the first pattern being different than the second pattern.

8. The workpiece processing method according to claim 1, wherein the part support further comprises a third support region, wherein the second support region is arranged between the first support region and the third support region in a direction transverse to the discharge direction, and the first support region and the third support region project towards the processed product to a greater extent than the second support region.

9. A workpiece processing method, comprising:

positioning a workpiece relative to a processing device to undergo a workpiece processing operation;

producing a processed product as a result of the workpiece processing operation, the processed product being of a first type or of a second type that is different from the first type; and

discharging the processed product using a discharge device that comprises a discharge flap, the discharge flap being pivotal into a discharge position inclined downward relative to a horizontal position and defining a discharge direction, and the discharge flap comprising a part support on an upper side thereof,

wherein the processing device is fitted to the discharge flap,

wherein the part support comprises first and second support regions that extend in the discharge direction;

wherein the first support region comprises first properties configured to support the processed product being of the first type such that the first support region is configured to move the processed product being of the first type in the discharge direction;

wherein the second support region comprises second properties that are different from the first properties of the first support region and that are configured to support the processed product being of the second type such that the second support region is configured to move the processed product being of the second type in the discharge direction;

wherein the workpiece, undergoing the workpiece processing operation, is positioned in a manner such that;

the processed product being of the first type resulting from the workpiece processing operation is arranged on an upper side of the processing device when the workpiece processing operation is finished, such that the processed product being of the first type is transferred from the upper side of the processing device to the first support region after the discharge flap has been pivoted into the discharge position, or

the processed product being of the second type resulting from the workpiece processing operation is arranged on the upper side of the processing device when the workpiece processing operation is finished, such that the processed product being of the second type is transferred from the upper side of the processing device to the second support region after the discharge flap has been pivoted into the discharge position; and

wherein the first support region is constructed of a support brush comprising one or both of first bristles and first bristle bundles and the second support region is constructed of a support brush comprising one or both of second bristles and second bristle bundles, the one or both of the first bristles and the first bristle bundles having a different angle of orientation with respect to the discharge direction than the one or both of the second bristles and the second bristle bundles.
