JP 2002-068411 A

  In the storage shelf of Patent Document 1, a plurality of types A, a plurality of types B, a plurality of types C, and a plurality of types D are stored. When it is specified in the means that three articles are to be delivered to the delivery location in the order of the kind A article, the kind B article, and the kind C article, the kind A article and the kind B or kind C article If there is no paired article (article that can be taken out from the storage shelf at the same time by the transport means) and there is a paired article of type B and type C, the exit command means determines whether the type B article and type C article Two articles are allocated as allocated articles, and the allocated allocation articles are taken out from the storage shelves at the same time, and then delivered together and commanded to be delivered to a delivery location. In addition, if there is no article that becomes a paired article in this way, the delivery instruction means outputs two twin articles, that is, an article of type A and an article of type B (the delivery order is the earliest kind of article and the delivery order is 2). The second type article) is allocated as the allocated article, and the allocated allocation articles are sequentially taken out from the storage shelf, and then transported together to issue a delivery command for delivery to the delivery location.

  In the conventional article storage facility, when two articles that are the target of multiple delivery orders are of different types, two different types of articles are allocated as provisioned articles, and two different types of allocated articles have been allocated. Allotted articles are transported together and delivered to the delivery location. Therefore, goods of different types are delivered to the delivery location at the delivery location, and compared to the case where the same type of product is delivered, the work on the goods after delivery (for example, the goods delivered to the delivery location are The operation of branching and transporting to the transport destination is complicated.

  This invention is made in view of the said actual condition, The objective is to provide the article storage equipment which can aim at the simplification of the operation | work with respect to the article after delivering an article to the delivery location. .

The article storage facility according to the present invention collects and conveys a plurality of articles together with a storage shelf that stores articles assigned with attribute information indicating processing contents after delivery in a state in which the articles are arranged in the vertical direction and the horizontal width direction of the shelf. Conveying means for conveying articles stored in the storage shelves in the form and issuing them to a delivery location, and issuing a delivery instruction to allocate the articles delivered to the delivery location as provisioned items and to release the allocated items to the delivery location A delivery command means for repeatedly instructing, and an operation control means for controlling the operation of the transport means to transport the provisioned article from the storage shelf to the delivery location based on the delivery command of the delivery command means. And
The first characteristic configuration is provided with order designating means for designating an article to be delivered at the delivery location and a delivery order of the article, wherein the delivery instruction means is the article designated by the order designating means and the allocation If there is an article that has the same attribute information as the first article in addition to the first article in the order of delivery in addition to the article that has not been assigned as an article, the goods that have the same attribute information will be issued. A plurality of articles are allocated as the allocated articles up to the number of articles that can be transported by the transport means preferentially from the previous order, and the allocated allocated articles are transported collectively. In order to issue a plurality of delivery commands to be delivered to a delivery location as the delivery command, and to an article designated by the order designating unit and not allocated as the provisioned article, If there is no article to which the same attribute information as that of the earliest article is assigned in addition to the article having the earliest warehouse order, the article having the earliest delivery order is allocated as the provisioned article. It is configured to instruct a single delivery command as a delivery command to transport the allocated articles that have been allocated and to issue to the delivery location ,
The goods instructing means has the same attribute information as the earliest article in addition to the earliest article in addition to the article designated by the order designation means and not allocated as the provisioned article. When there is no article to which the item is assigned, the set waiting time for the article has elapsed from the time when the article with the earliest delivery order is designated by the order designating means until the article is allocated as the provision article. Allocates the article with the earliest delivery order as the provisioned article and commands the single delivery command, and does not command the single delivery command when the set time for waiting for the article has not elapsed. It is in the point which is comprised.

  That is, an article that is specified by the order specifying means and is not allocated as a provisioned article is assigned with the same attribute information as that of the first article in addition to the first article in the delivery order. If there is an item with the same attribute information, a plurality of items are allocated as provision items up to the number of items that can be conveyed by the conveying means with priority from the previous item in the order of delivery. The allocated provision items that have been allocated are collectively transported by the transporting means and delivered to the delivery location. In addition to the article designated by the order designating unit and not allocated as the provisioned article, an article assigned with the same attribute information as the article with the first delivery order in addition to the article with the first delivery order is assigned. If there is no such item, the item with the earliest issue order is allocated as the allocated item, and the allocated allocated item is transferred by the transfer means and output to the output location.

  To illustrate a specific example, the number of articles that can be transported by the transport means is two, and at the delivery instruction means, an article a1 of attribute information A1, an article b of attribute information B1, an article a2 of attribute information A2, and attribute information When the article is specified in the order of the article a3 of A and the article b2 of attribute information B, the article a2 and the article a3 to which the same attribute information A as that of the article a1 is assigned in addition to the article a1 with the earliest delivery order. Therefore, two items, the item a1 and the item a2, which are preferentially issued from the first item in the order of issue among the items a1, the item a2, and the item a3 having the same attribute information by the issue command means are allocated items. A multiple delivery command is issued that is allocated, and transports the article a1 and the article a2 together to be delivered to the delivery location. When a plurality of delivery commands are instructed in this way, the operation of the transport means is controlled by the work control means so that the articles a1 and the articles a2 are collectively transported and delivered to the delivery location. Are delivered in the order of article a1 and article a2.

  Then, when the article a1 and the article a2 are allocated as the allocated articles as described above, the articles specified by the order designating unit and not allocated as the allocated articles are the items b1 of the attribute information B and the attribute information A. The item a3 is the item b2 of the attribute information B. Since there is an article b2 to which the same attribute information B as that of the article b1 is assigned in addition to the article b1 with the earliest delivery order, the goods instructing means determines whether the article b1 and the article b2 have the same attribute information. Two articles are allocated as provisioned articles, and a plurality of delivery commands are issued in which the articles b1 and b2 are transported together and delivered to a delivery location. Then, when a plurality of delivery commands are instructed in this way, the operation of the transport means is controlled by the work control means so that the goods b1 and the goods b2 are transported together and delivered to the delivery location. Is delivered in the order of the article b1 and the article b2 after the article a1 and the article a2.

  As described above, when the article b1 and the article b2 are allocated as the allocated articles, the articles specified by the order designating unit and not allocated as the allocated articles are only the articles a3 of the attribute information A. Since there is no article to which the same attribute information A as the article a3 is assigned other than the article a3 with the earliest delivery order, the article a3 with the earliest delivery order is allocated as the provision article by the delivery instruction means. A single delivery command for conveying the one article a3 and issuing it to the delivery location is instructed. Then, when a single exit command is instructed in this way, the work control means controls the operation of the transport means to transport the article a3 and output it to the exit location, and the article a1 and the article a2 are placed at the exit location. The article a3 is delivered after the articles b1 and b2.

  As described above, when a plurality of articles are collectively transported and delivered to a delivery location, since the plurality of articles to be delivered all have the same attribute information, the work after delivery can be simplified. it can. For example, when the attribute information is information indicating the transport destination of an article transported from the exit location, all the articles delivered at the exit location may be transported to the same transport destination. The work of branching and transporting a plurality of articles to the transport destination can be simplified.

  Accordingly, it has become possible to provide an article storage facility capable of simplifying the work on the article after the article is delivered to the delivery location.

As a specific example, when the number of articles that can be conveyed by the conveying means is two and only the article a1 of the attribute information A is designated by the order designating means, the article a1 with the earliest delivery order is designated. In addition, there is no article to which the same attribute information A as that of the article a1 is assigned. When the set time for waiting for the article has elapsed since the article a1 is designated by the order designating means until the article is allocated as the provisioned article, a single delivery instruction for issuing the article a1 is issued. Commanded by means. Then, when a single exit command is instructed in this way, the work control means controls the operation of the transport means to transport the article a1 to the delivery location, and the article a1 is delivered to the delivery location. .

  In addition, when the set time for waiting for an article has not passed after the article a1 is designated by the order designating unit until the article is allocated as the provisioned article, a single delivery instruction for issuing only the article a1 is immediately issued. When the order designation means does not newly designate the delivery of the article of the attribute information A until the set time for the article standby elapses, a single delivery instruction for issuing the article a1 is instructed and the article standby is performed. When the delivery of the article a2 of the attribute information A is newly designated by the order designating means before the set time elapses, a multiple delivery instruction for issuing the article a1 and the article a2 is instructed. When a plurality of delivery commands are instructed in this way, the work control means controls the operation of the transport means so as to transport the goods a1 and the goods a2 together and deliver them to the delivery location, and the goods a1 and the goods a2. And are issued at the delivery location.

  Accordingly, in addition to the article designated by the order designating unit and not allocated as the provisioned article, the article having the same attribute information as the article issued first in addition to the article issued first is assigned. If there is no such item, it waits to issue a single issue command until the set time for waiting for items has elapsed, thereby increasing the opportunity to issue multiple issue commands and transporting a plurality of items having the same attribute information together. be able to. In addition, when a set time for waiting for an article has passed, a single article issue command is issued to issue one article, so that it is possible to avoid delaying the delivery of the designated article more than necessary.

A second feature configuration of the article storage facility according to the present invention is the first feature configuration, wherein the delivery instruction means is assigned to an article designated by the order designation means and not assigned as the provisioned article. If there is no article to which the same attribute information as that of the earliest article is assigned in addition to the earliest article, the article after the second order after the set time for waiting for the article has passed. If there are a plurality of articles to which the same attribute information is assigned, a plurality of articles having the same attribute information in the order of delivery are limited to the number of articles that can be transported by the transport means preferentially from the previous article. A plurality of items that are assigned as the provisioned items, and the plurality of assigned items are transported together, and the items are delivered to the delivery location before the first item in the order of delivery. Certain decree in that it is configured to direct as the outgoing command.

  That is, as a specific example, the number of articles that can be transported by the transport means is two, and the goods instructing means instructs the article a1 of attribute information A1, the article b2 of attribute information B1, and the article b2 of attribute information B When the order is specified, there is no article to which the same attribute information A as that of the article a1 is assigned in addition to the article a1 having the highest delivery order. Since there are the articles b1 and b2 to which the same attribute information B is assigned to the second and subsequent articles in the delivery order, after the article a1 is designated by the order designating means, the article is allocated as the provisioned article. If the set time for waiting for the article has not elapsed, a multiple multiple delivery command for issuing the articles b1 and b2 is instructed. In this way, when the advance multiple delivery command is instructed, the work control means controls the operation of the transport means so as to transport the goods b1 and the goods b2 together and deliver them to the delivery place. The article b1 and the article b2 are delivered before the article a1 having the highest delivery order.

  Accordingly, there is no article to which the same attribute information as that of the first article is assigned, and the article is designated as the provisioned article after the first article is designated by the order designating means. If there is more than one item with attribute information different from the attribute information of the earliest item when the set time for waiting for the item has not passed before allocation, the item with the earliest issue order is issued. By issuing the advance delivery command until the command for issuing a single delivery command is issued (until the set time for waiting for the article has elapsed), the advancement command for multiple delivery is issued while waiting for the delivery of a single delivery command. Articles subject to a delivery instruction can be delivered efficiently.

The third characteristic configuration of the article storage facility to the present invention, the first or second feature Oite in configuration, the storage rack is divided corresponding to a plurality of areas in the attribute information, wherein the storage rack an article Is stored in the area corresponding to its own attribute information.

  That is, since articles having the same attribute information are stored in the same area, articles having the same attribute information are easily stored in locations close to each other on the storage shelf. Therefore, when a plurality of delivery instructions are instructed and a plurality of articles are taken out of the storage shelf and transported toward the delivery location, the plurality of articles are stored in locations close to each other, so that the plurality of articles are efficiently stored. The product can be taken out from the storage shelf, and the goods can be efficiently discharged by the conveying means.

In the fourth feature configuration of the article storage facility according to the present invention, in any one of the first to third feature configurations, the attribute information is information indicating a transport destination of an article transported from the delivery location. It is in.

  That is, when a plurality of articles having the same attribute information are transported together and delivered to a delivery location by the transfer device, the delivery destinations of the plurality of articles are all the same. Sorting work can be simplified for sorting to the destination according to the attribute information.
