Abstract

Apparatus for separating workpieces which preferably consist at least in sections of wood, wood-based materials, plastic or the like, having a workpiece magazine with a magazine area for holding a plurality of workpieces, in particular a stack of workpieces, a discharge device for discharging a workpiece out of the workpiece magazine, characterized in that the apparatus has a feed device which is set up to feed at least one workpiece held in the workpiece magazine to the discharge device.

First claim

The invention claimed is:

1. An apparatus for separating workpieces which preferably consist at least in sections of wood, wood-based materials, or plastic comprising:
a workpiece magazine with a magazine area for holding a plurality of workpieces, in particular a stack of workpieces; and
a discharge device for discharging a workpiece out of the workpiece magazine,
wherein the apparatus has a feed device which is set up to feed at least one workpiece held in the workpiece magazine to the discharge device,
wherein the feed device has at least one second feed element, which is arranged at least in sections at a distance from edges of the magazine area, and
wherein the second feed element is bolt-shaped or strip-shaped at least in sections.

2. The apparatus according to claim 1 , wherein the feed device has first feed elements, which are arranged at least in sections in the region of edges of the magazine area.

3. The apparatus according to claim 1 or 2 , wherein the at least one second feed element is arranged at least in sections in between the first feed elements.

4. The apparatus according to claim 2 , wherein the first feed elements and the second feed element are mechanically and/or electronically connected to each other.

5. The apparatus according to claim 1 , wherein the discharge device has at least one discharge element for discharging a workpiece out of the workpiece magazine, the discharge element preferably having a circulating endless conveyor.

6. The apparatus according to claim 5 , wherein the discharge device has two discharge elements, in particular circulating endless conveyors, it being preferable that the second feed element of the feed device is arranged between the discharge elements.

7. The apparatus according to claim 1 , wherein characterised in that it has a suction device for drawing a workpiece to be discharged to the discharge device.

8. The apparatus according to claim 7 , wherein the suction device has at least one suction opening which ends in the region of the discharge device.

9. The apparatus according to claim 7 or 8 , wherein the suction device has a negative pressure line with a closing device by means of which the negative pressure supply in the negative pressure line can be at least partially interrupted.

10. The apparatus according to claim 9 , wherein the closing device is synchronised with the feed device, preferably is operated by the feed device.

11. A machining device for machining workpieces which preferably consist at least in sections of wood, wood-based materials, or plastic or the like, comprising:
a separating apparatus according to claim 1 ; and
a machining unit for performing the workpiece machining.

12. A method for separating workpieces which workpieces preferably consist at least in sections of wood, wood-based materials, or plastic or the like, comprising the steps:
holding a plurality of workpieces, in particular a stack of workpieces, in a magazine area of a workpiece magazine;
feeding, by a feed device, at least one workpiece held in the workpiece magazine to a discharge device; and
discharging, by the discharge device, the at least one workpiece,
wherein the feed device has at least one second feed element, which is arranged at least in sections at a distance from edges of the magazine area, and
wherein the second feed element is bolt-shaped or strip-shaped at least in sections.

13. The method according to claim 12 , wherein a first and/or second feed element is/are at least partially lowered during feeding.

14. The method according to claim 12 or 13 , wherein the workpiece, preferably the lowest workpiece of a workpiece stack, is drawn in, it being preferable that the workpiece is further brought into contact with one or a plurality of discharge elements.
