Abstract

PURPOSE:To enhance work-efficiency by forming two article handling spaces at the end part of a shelf so that redepositing of an article for the preceding stage and discharging of an article for the following stage can be performed at the same time. CONSTITUTION:Two partitioned spaces located at the bottom end parts of a shelf 1 are formed into article-handling spaces 13 and 14. And the inner end of an picking conveyor of a chain conveyor type is placed over these article-handling spaces 13 and 14. The outer article-handling space 13 is provided with both an article receiving/discharging device 4 and an article-receiving stand 15 of a discharging elevator type, which is able to shift an article 8 between itself and a picking conveyor 10, which the inner article-handling space 14 is provided with an article-receiving stand 16 of a depositing elevator type, which functions in the same manner as the stand 15. Thus, by using the said two article-receiving stands properly, both redepositing of an article for the preceding stage and discharging of an article for the following stage can be performed simultaneously for efficient order picking of articles.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a shelf having a plurality of compartment storage spaces, a cargo delivery device that can travel along the shelf and transfer loads between the compartment storage spaces, and and a picking conveyor, the inner end of which is located within the cargo handling space formed at the end of the picking conveyor, and the picking conveyor is configured such that the cargo can be delivered by a cargo delivery device between the inner end of the picking conveyor and the inner end of the picking conveyor. This is related to warehouse equipment.

FIG. 1 shows a conventional pickable warehouse facility. That is, (1) is a shelf arranged in parallel, and has a plurality of divided storage spaces (2) in the vertical direction and the horizontal direction. (3
) is a passage formed between the shelves (1), in which the shelves (
1) is provided with a cargo delivery device (4) that is movable along the road. This cargo delivery device (4) has a pair of front and rear posts (5)
The elevating platform (6), which can be raised and lowered by being guided by these posts (5), is provided with a fork (7) that can be moved laterally. Therefore, the cargo delivery device (4) is controlled by the traveling movement along the shelf (1), the lifting movement of the lifting platform (6), and the movement of the fork (
By combining the movement with 7) lateral commuting, it becomes possible to transfer cargo (8) (in fact, cases and pallets that support goods) to and from the intended compartment storage space (2). . One compartment storage space on the end fi-T' stage of one shelf (1) is formed into a handling space (9), and its inner end is located within this cargo handling space (9). A picking conveyor αq is disposed extending outside the end of the shelf (1). The picking conveyor OQ is a mobile loading platform dI)
The cargo handling device (4) has a cargo handling space (9
The cargo (8) can be delivered to and from the mobile cargo receiving platform 0]) located at ). A conveyor @ is placed outside the end of the other shelf (1).

To explain the order picking operation in such a conventional configuration with reference to FIGS. 1 and 2, first, the cargo delivery device (
4) takes out the load (8) from the divided storage space (2) and faces the load handling space (9). Then, the load (8) is transferred onto the moving receiving platform ttn. Next, the picking conveyor is activated, and the cargo (8) is transferred onto the moving receiving platform ttn as shown by the imaginary line.
8) Move to the picking position.

Then, order picking is performed, and a part of the loaded cargo (8) is transferred to the transport conveyor (2) using a hoist or by hand.

After that, the picking conveyor 00 is operated in reverse, and the cargo (
8) is returned to the cargo handling space (9). Next, the cargo (8) on the movable cargo receiving platform 0 is received by the cargo delivery device t (4) and returned to the intended compartment storage space (2). After that, a new load (8) is taken out.

According to the conventional system that performs operations such as 1 and 2, only one load (8) can be handled in the picking conveyor Q□.

During picking work, etc., use the cargo delivery device i! (4
) and wait →. The fact that the cargo handling device (4) has such a long operation stop time means that the cycle time of the cargo handling operation is long9, making it impossible to carry out efficient order picking operations.

The object of the present invention is to install a picking-enabled warehouse where the cargo delivery equipment can be operated at all times and efficient order picking operations can be carried out. 'It is in the point of providing.

In order to achieve the above object, the pickable warehouse equipment of the present invention forms two cargo handling spaces at the ends of the shelves, and positions the inner end of the picking conveyor across these cargo handling spaces, and Each of the cargo handling spaces is provided with an elevating cargo receiving platform capable of transferring cargo to and from the cargo delivery device and the picking conveyor.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. Note that the same reference numerals as in the conventional example (FIG. 1) indicate the same or almost the same configuration. That is, (1) is a shelf, (2
) is compartment storage space, (3) is aisle, (4) is cargo delivery device, (5) is boss), (6) is lifting platform, (7) is fork, (8) is cargo, αQ is for picking Conveyor, @
- is a conveyor. In the present invention, the two compartment storage spaces at the bottom end of one shelf are the cargo handling space u31.
14, and these cargo handling spaces U31
141c Jf is where the inner end of the chain conveyor style picking conveyor is located. In addition, inside the outer cargo handling space (to), there is provided an elevating cargo platform aυ for unloading that can transfer cargo (8) to and from the cargo delivery device (4) and the picking conveyor a0, and further inside In the cargo handling space (141), there is provided an elevating cargo receiving platform α for warehousing that performs the same function.

Next, order picking work will be explained with reference to FIGS. 2(B), 5, and 4. First, the cargo delivery device (4) takes out the cargo (8) from the divided storage space (2) and faces the cargo handling space (to). Then, the cargo (8) is transferred onto the elevating cargo receiving platform (top) for unloading. Next, the elevating loading platform Uf9 is lowered.

By operating the picking conveyor t11, the load (8) is moved to the picking position. Then, order picking is performed, and a part of the cargo (8) is transferred to the conveyor a2 side by using a hoist or manually. After that, the picking conveyor α1 is operated in reverse, and the load (8) is transferred to the load handling space aa.
Vcf and pass it to the elevating receiving platform uO for warehousing.

By the way, the cargo (8) that was delivered to the elevating receiving platform U6 for warehousing in the previous process is transferred to the elevating receiving platform 11 for warehousing in the current process.
Delivery of cargo delivered to υ! [It is received by (4), and during the order picking operation in the current process,
It is returned to the target compartment storage recess (2). After that, a new load (8) is taken out.

According to the pickable warehouse equipment of the present invention, the following effects can be expected. In other words, by using two load receiving tables, it is possible to handle two loads at the same time on the picking conveyor. It is possible to re-enter the warehouse and take out the cargo for the next process. Being able to operate the cargo delivery device at all times in this way allows the cycle time of cargo handling operations to be shortened, thereby allowing for efficient order picking operations.
