Description

  The present invention relates to an article input method, and more particularly, to an article input method to a container in which an article is input into each container while a plurality of containers are conveyed by a conveyor.

  Conventionally, containers (for example, containers, cardboard boxes, etc.) corresponding to each sorting destination are transported by a conveyor as sorting equipment for efficiently sorting a wide variety of goods into a plurality of sorting destinations (for example, stores, customers, etc.). A picking facility is used in which an operator picks an ordered article designated by a digital display or the like from an article storage shelf and puts it into the designated container (for example, see Patent Document 1 below).

  In addition, in order to further increase the efficiency of the sorting operation, an article loading device that automatically places an ordered article picked from an article storage shelf into each container instead of manually is used (for example, the following) Patent Document 2). According to this article input device, it is possible to softly input an article into each container without stopping the conveyance of each container without damaging the article.

  However, in this sorting operation, it is common that the amount of articles put into each container differs depending on the sorting destination. If the amount of articles put into the container is relatively large, the article once thrown out falls outside the container. In rare cases. Therefore, conventionally, it is necessary to further provide a detection means for detecting the presence or absence of the article by measuring the weight of the entire container after the article is put in, and it is necessary to stop the conveyance of the container at the time of detection. There was a difficulty that caused the efficiency of sorting work to decrease.

  The present invention has been made in view of the above-described problems in the conventional article loading process into containers, and even if articles are almost filled into each container. It is an object of the present invention to provide an article input method capable of reliably preventing a product from falling.

A loading guide mounting process for mounting a loading guide on the container on the conveyor, an article loading process for loading an article into the container on which the loading guide is mounted, and the loading guide from the container in which the article is loaded. And a charging guide removing process for removing the guide.

In particular, the present invention is characterized in that the charging guide is attached to the container when the ratio of the amount of articles charged into the container with respect to the capacity of the container is equal to or greater than a preset value.

In the present invention, in particular, the charging guide is formed of a cylindrical body that has openings at both ends and can accommodate the container, and is placed on the transport surface of the conveyor with the one opening facing down. When the height of the other opening is larger than the height of the opening of the container, and in the charging guide mounting step, the charging guide is placed over the container and placed on the transport surface of the conveyor. Thus, the charging guide is mounted on the container.

  Furthermore, according to the present invention, the charging guide has a cylindrical body that has openings at both ends and can be inserted into the container, and is placed on the bottom surface of the container with the one opening facing down. The height of the other opening is larger than the height of the opening of the container, and in the charging guide mounting step, the charging guide is inserted into the container and placed on the bottom surface of the container. The charging guide is mounted on the container.

  Furthermore, in the present invention, the charging guide is formed of a cylindrical body having openings at both ends and can be placed on the opening edge of the container. In the charging guide mounting step, the charging guide is connected to the container. The loading guide is mounted on the container by being placed on the opening edge.

  According to the article loading method according to the present invention, the loading guide mounting process is performed and the loading guide is mounted on each container before performing the article loading process for loading the article into each container. Even when an article is thrown in, it is possible to reliably prevent the article from dropping when the article is thrown in with the throwing guide. In addition, since it is not necessary to attach the input guide to each container when the article is input, the efficiency of the sorting operation is not reduced.
