Description

  The present invention relates to a picking system in various distribution centers, warehouses, and the like, and more particularly to a picking system that realizes efficient sorting of low-frequency products and enables effective use of the space in the distribution center and warehouse.

  Distribution centers, warehouses, etc. have storage shelves that are categorized by supplying goods based on order information from storage warehouses that stock goods, and from there, the necessary quantity of goods according to each customer's order. Picking work that is taken out and sorted into regions, districts, areas, etc. is performed.

  As an example of a basic form of picking work of high-frequency goods, a storage shelf with a display in which articles are classified in a plurality of picking work zones partitioned along a moving direction of a conveying means such as a conveyor with a display, and An operator dedicated to the zone is assigned to take out the requested item from the storage shelf according to the picking instruction that indicates the customer's item request information (sorting destination, product type, quantity, etc.) and convey it by a conveyor, etc. A so-called digital picking system in which a requested customer's shipping destination is stored among the received product storage boxes.

  Such a picking system can respond to diversification of goods and customers handled, rapid increase in mail-order sales using the Internet and TV, etc., and reduction of logistics costs. Has been able to satisfy the demand to do. In particular, it was an optimal system for handling high-frequency products with relatively few varieties and large quantities.

  However, in recent years, there has been a rapid increase in the range of goods handled in response to customer demands, and there are a wide variety of varieties, but the quantity is extremely small, and there is a need to handle goods that are not regularly ordered. It was. Conventionally, in such a small-scale picking work, a picking cart equipped with a bar code reader, a display, a printer and the like for supporting the picking work has been used. When using such a picking cart, it is efficient to transfer as many customer orders as possible from the storage warehouse that stocks the goods to the picking cart. In order to efficiently perform the sorting, it is necessary to prepare a large number of such expensive picking carts, and there is a problem that the capital for equipment becomes high.

  In order to deal with such a problem, in Patent Document 1, a carrier that loads and conveys only an article or an article storage box is combined with a cart body that is equipped with a digital device that supports picking work, and the article is stored from a storage. A method has been proposed in which after transferring, these are separated and only the carrier is delivered to the sorting process for each shipping destination. However, in the sorting process for each shipping destination, it is necessary to combine the carrier and the cart again. That is, although the ordered article is accurately transferred to the carrier, there is a problem that the work load is large that the coupling and separation between the carrier and the cart body are required at least twice.

  Further, in Patent Document 2, as in Patent Document 1, a transporting mobile body corresponding to the carrier and a work support mobile body corresponding to the cart body are combined to transfer articles from a storage, To separate. However, in the sorting process for each shipping destination, a frame with a display device is provided so as to be parallel to the conveyor of the basic form of the picking operation described above, and the transporting mobile body is coupled to the frame. And since the picking instruction based on the customer's article request information is shown in the frame, the requested customer is taken out of the article storage boxes taken out from the transporting mobile body and conveyed by a conveyor or the like. A method of putting the product into the article storage box at the shipping destination has been proposed. In this case as well, the equipment and system for picking low-frequency products can accurately transfer the ordered items to the transporting mobile unit. There arises a problem that separation is necessary, and that the transportation vehicle and the frame with the indicator need to be coupled and separated. Moreover, since the frame with a display is installed in parallel with the conveyor, there is a problem that the types of articles that can be handled at a time are reduced.
