Abstract

A picking device for piece goods is disclosed, in which cleaning of the picking device is facilitated. The picking device may include a shelf row having shelf bases, each including a plurality of storage chutes, and a retrieving device, via which piece goods can be retrieved. A shelf base may include a frame structure, chute partitions, chute bases, and blocking devices, which are coupled to a control device. Two chute partitions and one chute base may define one elongate storage chute, assigned to each chute base is a support device, on which the chute base rests and which is designed such that another chute base can be slid between the resting chute base and the support device. Assigned to each chute base is a holding means, which prevents the chute base from sliding in the longitudinal direction of the storage chute when the chute base is on the support device.

First claim

What is claimed is:

1. A method for operating a picking device comprising:
providing at least one shelf row having at least one shelf having a plurality of shelf bases arranged one above the other, each extending in a plane and each comprising a plurality of storage chutes, wherein at least one of the plurality of shelf bases comprises (i) a frame structure, (ii) a plurality of chute partitions, (iii) a plurality of chute bases, and (iv) a plurality of blocking devices, wherein, each chute base, along with two chute partitions, define one elongate storage chute having a stocking end and a retrieving end, wherein a blocking device is arranged at each of the retrieving ends, and each chute base comprises a support device, on which the chute base rests and which is configured such that a further chute base can be slid underneath the resting chute base, and each chute base comprises a holder that restricts the chute base from sliding in a longitudinal direction of the storage chute when the chute base rests on the support device;
lifting an old chute base resting on a support device at the retrieving end or the stocking end of the corresponding storage chute;
sliding a new chute base underneath the old chute base on the support device,
removing the old chute base; and
fixing the new chute base against sliding without preventing the new chute base from being lifted perpendicularly away from the support device.

2. The method according to claim 1 , wherein the chute bases are wedge-shaped, at least in sections, at the stocking end, and wherein the method further comprises:
lifting, at the stocking end of the corresponding storage chute, the old chute base resting on the support device by inserting the new chute base,
wherein the new chute base is complementary, at the retrieving end, to the stocking end of the old chute base.

3. The method according to claim 1 , wherein sliding the new chute base underneath the old chute base on the support device comprises sliding the new chute base underneath the old chute base while at least one piece good rests on the old chute base.

4. The method according to claim 3 , further comprising operating one of the blocking devices to allow the at least one piece good to fall onto a retrieving device.

5. The method according to claim 4 , wherein operating the one of the blocking devices comprises retracting a stopping device into a main body of the one of the blocking devices.

6. The method according to claim 1 , further comprising
moving piece goods into the picking device using at least one stocking device; and
removing the piece goods from the at least one stocking device using an operating device, which is configured to be displaced horizontally and vertically in front of the shelf row.

7. The method according to claim 1 , wherein the support devices are configured. such that the chute bases are supported so as to be movable along a vertical axis of the storage chutes.

8. The method according to claim 1 , wherein the chute partitions comprise support sections, and wherein two support sections form one support device in each case.

9. The method according to claim 1 , wherein each holder is formed at a section of an assigned chute base corresponding to the stocking end of a storage chute.

10. The method according to claim 1 , wherein the chute bases each comprise at least one articulated section.

11. The method according to claim 1 , further comprising:
determining a degree of soiling of a chute base using a sensor of the chute base; and
forwarding the degree of soiling to a control device.

12. The method according to claim 1 , wherein each chute base comprises a combination detection and display device, the method further comprising determining and displaying a degree of soiling of each chute base.

13. A method, comprising:
restricting, with a holder, a chute base from sliding in a longitudinal direction of an elongate storage chute, the elongate storage chute extending in the longitudinal direction from a stocking end to a retrieving end and defined by the chute base and two separate chute partitions that each include a portion on which the chute base rests to combine to form a support device for the chute base;
lifting the stocking end or the retrieving end of the chute base perpendicularly away from the support device;
sliding an additional chute base between at least a portion of the chute base and the support device;
removing the chute base; and
fixing the additional chute base against sliding in the longitudinal direction without preventing the additional chute base from being lifted perpendicularly away from the support device at the stocking end or the retrieving end.

14. The method of claim 13 , wherein fixing the additional chute base against sliding comprises fixing the additional chute base against sliding with the holder.

15. The method of claim 13 , wherein lifting the stocking end or the retrieving end of the chute base perpendicularly away from the support device comprises lifting the stocking end or the retrieving end of the chute base perpendicularly away from the support device while at least one piece good rests on the chute base.

16. The method of claim 15 , further comprising operating a blocking device at the retrieving end of the elongate storage chute to allow the at least one piece good to fall onto a retrieving device.

17. The method of claim 13 , further comprising:
determining a degree of soiling of the chute base using an electronic sensor; and
providing the degree of soiling to a control device of a picking device comprising the elongate storage chute.

18. A method, comprising:
providing at least one shelf row of a picking device, the at least one shelf row having at least one shelf having a plurality of shelf bases, each shelf base extending in a plane and each comprising a plurality of storage chutes, wherein at least one of the plurality of shelf bases comprises (i) a frame structure, (ii) a plurality of pairs of chute partitions, each pair defining one of the plurality of storage chutes and forming a support structure, and (iii) a plurality of blocking devices;
resting each of a plurality of chute bases on a corresponding support structure formed from a corresponding pair of chute partitions to define the plurality of storage chutes, each extending in a longitudinal direction between a stocking end and a retrieving end; and
fixing each of the chute bases against sliding in the longitudinal direction without preventing at least one end of each of the chute bases from being lifted away from the support structure upon which that chute bases rests, to allow sliding of a new chute base between a selected one of the chute bases and the support structure upon which that chute bases rests.

19. The method of claim 18 , further comprising blocking, with one of the plurality of blocking devices, a piece good resting on a corresponding one of the chute bases from sliding along the corresponding one of the chute bases in the longitudinal direction.

20. The method of claim 18 , further comprising sliding the new chute base between the selected one of the chute bases and the support structure upon which that chute bases rests.
