Abstract

A process and a device for handling and stacking pressed bales in a bale storage facility with at least one stacking device (1), which has a traveling crane bridge (3), a bogie truck (4) and a hanging-down guide beam (5). A grabbing device is provided for one or more, preferably three pressed bales (2) is arranged on it vertically movably and rotatably around the vertical axis. The stacking device (1) has a remote control and a fully automatic, computer-aided storage management system. After loading into the storage area, the bales can be re-sorted in the bale storage facility fully automatically and arranged according to the type of bale, grade and other criteria.

Claims

1. A process for handling and stacking pressed bales in a bale storage facility, comprising the steps of:

providing compressed bales of fibers;

loading and removing the compressed bales from the bale storage facility with at least one multiaxially movable, automatic stacking device with a bale grabbing device, said grabbing device gripping the compressed bales from the side with lateral clamping movement;

supporting the grabbing device from above the compressed bales to provide access to the compressed bales from above the compressed bales, said step of supporting being provided with a stacking device having a substantially rigid member to avoid swaying of the grabbing structure;

stacking the compressed bales up one above the other in stacks consisting of a plurality of layers and arranged in rows, each compressed bale in each stack being in direct contact with another compressed bale in said stack; and

managing the bale storage facility with a storage facility management program and a data bank, wherein storage location and product-related data of each compressed bale are stored in the data bank.

2. The process in accordance with claim 1, wherein small stacks of two or more compressed bales are grabbed and handled together with said stacking device.

3. The process in accordance with claim 1, wherein small stacks are formed in one or more intermediate storage areas, said one or more intermediate storage areas being disposed before said bale storage facility.

4. The process in accordance with claim 1, wherein the stacks of bales arranged in said plurality of rows are arranged on a side of an aisle and extend at right angles to said aisle.

5. The process in accordance with claim 1, wherein said step of managing includes managing and controlling said bale storage facility automatically.

6. The process in accordance with claim 1, wherein said compressed bales are arranged in said bale storage facility according to product-related distinguishing criteria.

7. The process in accordance with claim 1, further comprising forming bales at a compressed bale formation location wherein said compressed bales are sorted and arranged in one or more of said intermediate storage areas at the time of the formation of the small stacks, said intermediate storage areas being provided adjacent to said bale formation location.

8. The process in accordance with claim 1, wherein said compressed bales are first loaded into the bale storage facility without arrangement and are then automatically re-sorted and arranged in the said bale storage facility at a location adjacent to said stacking device.

9. A process for handling and stacking pressed bales in a bale storage facility, comprising:

providing highly compressed bales of fibers as the pressed bales;

loading and removing the pressed bales from the bale storage facility with a stacking device with a traveling crane bridge, with a bogie truck, with a hanging-down guide beam and with a grabbing device for grabbing one or more said pressed bales from the side, said bogie truck being provided with rotating means for rotating said guide beam, said stacking device being provided with means for remotely controlling one or more of said traveling crane bridge, said bogie truck, said hanging-down guide beam and said grabbing device;

grabbing a pressed bale with the grabbing device from the side and holding the pressed bale with a lateral clamping movement;

guiding said pressed bales on said guide beam vertically movably and rotatably around a vertical axis; and

stacking the pressed bales up in stacks one on top of another with each bale in a stack in direct contact with an adjacent pressed bale in the stack, each stack consisting of a plurality of layers and said stacks being arranged in rows.

10. The process in accordance with claim 9, further comprising providing cooperation between said stacking device and an intermediate storage area, said intermediate storage area having a stack former.

11. The process in accordance with claim 10, wherein said intermediate storage area is provided with a plurality of separated storage places for pressed bale stacks.

12. The process in accordance with claim 11, wherein said storage places include a conveyor, said conveyor maintaining said bale stacks ready in a pick-up position.

13. The process in accordance with claim 10, wherein said stack former is provided with a displaceable and vertically movable bale grab.

14. The process in accordance with claim 10, further comprising connecting said intermediate storage area with one or more baling presses.

15. The process in accordance with claim 9, further comprising providing a delivery station for delivering pressed bales, wherein said stacking device cooperates with said delivery station.

16. The process in accordance with claim 9, further comprising controlling an entire facility including said stacking device and stacks and rows formed by said stacking device with a control means.

17. The process in accordance with claim 16, wherein said control means includes a computer with a storage facility management program and with a data bank, and a sorting program.

18. A process for handling and stacking pressed bales in a bale storage facility, comprising:

providing highly compressed bales of fibers as the pressed bales;

loading and removing the pressed bales from the bale storage facility with a stacking device with a traveling crane bridge, with a bogie truck, with a hanging-down guide beam and with a grabbing device for grabbing one or more said pressed bales from the side;

grabbing a pressed bale with the grabbing device from the side and holding the pressed bale with a lateral clamping movement;

guiding said pressed bales on said guide beam vertically movably and rotatably around a vertical axis;

stacking the pressed bales up in stacks one on top of another with each bale in a stack in direct contact with an adjacent pressed bale in the stack, each stack consisting of a plurality of layers and said stacks being arranged in rows; and

providing said grabbing device with a plurality of transversely movable forks, arranging the forks at spaced locations one on top of another and grabbing and clamping a small stack consisting of a plurality of said pressed bales on the sides of said pressed bales.
