6. The wood-processing system according to claim 1, wherein the at least one robot is movable linearly, at least in a first direction (X), in order to travel to deposit means (41-44) arranged in succession in the first direction (X).

7. The wood-processing system according to claim 1, wherein the workpieces (7) are moved in the buffer (7).

8. A wood-processing method in which planar workpieces (7) made of wood or wood-substitute material in a wood-processing system, comprising feeding workpieces (7) to a buffer (1) and buffering the workpieces (7) in the buffer (1), removing buffered workpieces (7) from the buffer (1) by a robot (2) in accordance with control criteria, and depositing the buffered workpieces (7) in a predetermined deposit position in a depositing device (4) that is separate from the buffer (1) or in another deposit position in the buffer (1) itself.

9. The wood-processing method according to claim 8, in which the robot (2), after depositing a workpiece (7) on a deposit means (41-44), receives a protective material from a storage means and applies it to said workpiece (7).

10. The wood-processing method according to claim 8, wherein the robot (2) is moved linearly along the depositing device (4) in a first direction (X).

11. The wood-processing method according to claim 9, wherein the robot (2) is moved linearly along the depositing device (4) in a first direction (X).

12. The wood-processing method according to claim 9, wherein the protective material is selected from the group consisting of protective paper, protective cardboard, and protective film.

13. The wood-processing method according to claim 11, wherein the protective material is selected from the group consisting of protective paper, protective cardboard, and protective film.

14. The wood-processing system according to claim 2, wherein the feed device (8) feeds the workpieces (7) to the buffer (1) sequentially.

15. The wood processing system according to claim 4, wherein the stationary deposit means is selected from the group consisting of pallets and shelves.

16. The wood-processing system according to claim 4, wherein the movable deposit means is selected from the group consisting of belt conveyors, roller conveyors, and brush carriages.

17. The wood-processing system according to claim 5, wherein the protective material is selected from the group consisting of protective paper, protective cardboard, and protective film.

18. The wood-processing system according to claim 6, wherein the at least one robot is movable linearly in parallel with the depositing device (4).

19. The wood-processing system according to claim 6, wherein the at least one robot is movable linearly on rails.

Description

BRIEF DESCRIPTION OF THE DRAWING

[0017] The invention will be explained in greater detail in the following with reference to the FIGURE of the drawings.

[0018] Said FIGURE is a schematic plan view of at least part of a wood-processing system according to the invention.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0019] The FIGURE shows a buffer 1 in which workpieces are buffered which enter the buffer 1 by means of a feed apparatus 8. The buffer 1 may be designed such that it retains the workpieces in a horizontal manner. Alternatively, it is equally possible to use the feed apparatus 8 to load a buffer 1 which retains the workpieces in a vertical orientation (i.e. perpendicular to the floor).

[0020] A depositing device 4 is arranged opposite the buffer 1 and, in the example shown, comprises a plurality of deposit means 41, 42, 43, 44 on which workpieces 7 can be deposited. As indicated in the example shown, the depositing device 4 may be a stationary apparatus. It is equally possible to use a conveying apparatus as a depositing device, for example, which e.g. conveys the workpieces 7 in the direction X and/or Y or also in a circle. According to the invention, the robot 2 is arranged between the buffer 1 and the depositing device 4, and said robot has a robot arm 3 by means of which a workpiece 7 can be gripped. In the example shown, the robot 2 is mounted on a guide apparatus 6, which may be a rail, for example. The robot is movable on the guide apparatus 6 in the direction X in parallel with the depositing device 4. In this way, the robot 2 can travel to the deposit means 41 to 44 of the depositing device 4 and workpieces 7 can be deposited thereon and/or removed from said deposit means. The range of action of the robot 2 is indicated by the line 5. The robot 2 is therefore capable of traveling to any point within the line 5. The workpieces which enter the buffer 1 by means of the feed apparatus 8 are removed from the buffer 1 by means of the robot 2 and are either deposited again at another point in the buffer 1 or are transported by the robot 2 to a deposit means 41 to 44 of the depositing device 4 and are deposited there. Likewise, workpieces 7 that are deposited on one of the deposit means 41 to 44 can be removed by the robot 2 and, for example, brought back into the buffer 1. It is also possible for the robot 2 to remove a protective material from a protective material from a protective-material store (not shown) and apply it to a workpiece 7 positioned on the deposit means 41 to 44.
