Description

Description: TECHNICAL FIELD The present invention relates to a picking system for picking up an article from a shelf by a picking indicator installed on a picking cart, and particularly to an error that is different from the instruction of the picking indicator. The present invention relates to a picking control device that prevents picking.

(Prior Art) As is well known, for example, in a wholesale trade, etc., based on order slips from each retail store, each of the corresponding products is collected from the products accumulated in the warehouse etc. I try to ship it to a certain store. In this case, in the wholesale business, a picking worker pushes a picking cart equipped with a plurality of article storage boxes corresponding to each shipping destination, goes around the shelves storing various articles, and stores each article based on the ordered article list. Order picking is performed in which a predetermined number of articles of a predetermined type are sequentially taken out from a box.

By the way, in the conventional picking work of this kind, the picking worker has a list (slip) to be picked and takes out a predetermined quantity of a predetermined article for each shipping destination based on the list, which requires a long working time. At the same time, there is a problem that errors are likely to occur, resulting in a decrease in work efficiency.

Therefore, recently, a picking indicator is installed on a picking cart, and a centralized management system using a computer is used to automatically indicate the position of the article to be taken out, the quantity of the taken out article by each shipping destination, and the like. After the completion of picking up, a picking system has been actively developed to inform the computer of the end of work by operating a reset switch attached to the picking indicator, and to issue a next picking up instruction. (See, for example, JP-A-63-112302).

However, there are still many points that need to be improved in the technology that introduces a centralized management system using a computer to improve the efficiency of picking work, and in various respects, it is sufficient for the needs of users. There is a strong demand for the development of a picking system that can answer these questions.

That is, in the case of the above-described picking system, the picking operator is instructed by the picking indicator installed on the picking cart the position on the shelf of the article to be taken out, but during the actual picking operation, However, there is a problem that the picking work is often carried out by mistaken picking of an article that is not the designated article, and the efficiency of the picking operation is reduced. The reason why this wrong picking is performed is, for example, that the position of the article is indicated by a combination of numerical values such as the column number of the shelf, the bay number, and the column number, and the numerical value is misread. There is a mistake in memorizing the numerical value by moving the eyes to the shelf and looking for the specified numerical value, and an illusion of the illusion of the correspondence between the item and the level indicating the position number of the item attached to the shelf. To be

(Problems to be Solved by the Invention) As described above, the conventional centralized management picking system has a problem that an article different from the instructed article is taken out and erroneous picking is easily performed. .

Therefore, the present invention has been made in consideration of the above circumstances, and it is possible to accurately take out the number of articles instructed by a picking indicator for each of a plurality of shipping destinations without error, and to improve the efficiency of picking work.
