[Conventional technology]

For such article sorting, equipment is capable of storing multiple types of articles in containers destined for the same shipping destination by storing the articles taken out by workers based on an article removal instruction into containers conveyed along the container conveyance line. It is designed to be stored, and it is also possible to replenish the remaining amount of articles appropriately as they are taken out.

Incidentally, the shelf is generally divided into a plurality of shelf parts along the transport direction of the container transport line, that is, along the width direction, and different types of articles are stored in each of the partitioned shelf parts. Then, instructions for taking out articles are given to each shelf section separately. In other words, a worker is assigned to each of the shelf sections, and while containers are being transported from the shelf section on the upper side of transport to the shelf section on the lower side of transport, each worker is assigned to the shelf section that each worker is in charge of. By taking out the articles from the container and storing them in the container, it becomes possible to store a wide variety of articles in the same shipping destination container while reducing the responsibilities of one worker. (Refer to Japanese Patent Application No. 61-103372, which was previously proposed by the present applicant) [Problems to be Solved by the Invention] In order to appropriately supply replenishment articles to a desired article storage zone, it is necessary to It is necessary to accurately stop the goods at a location facing the goods storage zone, and for this purpose, it is desirable to slow down the conveyance speed of the goods conveyance line. Therefore, it is desirable to increase the transport speed of the article transport line.

However, in the past, the line for transporting each article was driven at a constant speed, which made it impossible to satisfy both of the above demands.

The present invention has been made in view of the above circumstances, and includes:
The object of the present invention is to satisfy both of the requirements of accurately stopping replenishment articles at a location facing a desired article storage zone and efficiently performing article replenishment work.

[Means for solving problems]
