Claims (5)

1. 1. An article conveying device for accessing an article to an apparatus for accessing the article, comprising: a loading part for loading the articles from the outside of the equipment by an operator, and An article moving mechanism that conveys the article between the placement unit and the inside of the apparatus; The article moving mechanism includes: A transport supporting table for supporting the article; A first moving part for reciprocating the conveying support table between a first end and a second end, and A second moving unit that moves up and down the transport support table in a vertical direction; the mounting portion includes: a first portion arranged on an extension line of a moving path of the transport supporting table, that is, in a first direction; A pair of second portions arranged to sandwich the first portion in a second direction orthogonal to the first direction in plan view, and And a slide mechanism that moves at least a part of the placement portion between the first position and the second position when a position where the first portion is in contact with or in proximity to the transport support table located at the first end is set as a first position and a position where the first portion is away from the transport support table along the extension line from the first position is set as a second position.
2. 2. The article transport device according to claim 1, wherein each of the first portion and the pair of second portions has a positioning pin fitted to the article placed on the placement portion.
3. 3. The article conveying device according to claim 1 or 2, wherein the slide mechanism moves only the first portion in the placement portion.
4. 4. The article transport device according to claim 1 or 2, wherein the slide mechanism is configured to include a roller provided in the placement portion.
5. 5. The article transport device according to claim 1 or 2, further comprising a detection unit which is immovably disposed below the first portion and detects an identification unit attached to the article, An opening portion penetrating in the vertical direction is formed in the first portion, The opening is formed to be located above the detection portion when the first portion is located at the first position.

Description

Article conveying device Technical Field One aspect of the present invention is directed to an article transport apparatus for use with a warehouse system. Background Warehouse systems are known that house a plurality of items. For example, patent document 1 discloses a warehouse system including a loading unit for loading articles from outside the warehouse system by an operator, and an article moving mechanism (shuttle) for shuttle a transport support table (plate-like body) for supporting the articles between a delivery position of the articles to the loading unit and the inside of the warehouse system. The placement unit described in patent document 1 is configured by two article receiving units disposed so as to sandwich the conveying support table in a width direction orthogonal to both the conveying direction and the vertical direction of the conveying support table. In the placement portion configured as described above, the article is held by supporting the bottom two portions of the article from below, but there is a demand for holding the article more stably. Prior art literature Patent literature Patent document 1 japanese patent laid-open publication No. 2010-132381 Disclosure of Invention Problems to be solved by the invention Therefore, it is considered that a new support member extending in the width direction is arranged between the two existing article receiving portions, and three portions of the bottom of the article are supported from below the article. However, when such a new support member is disposed, there is a possibility that a part of the body such as the hand of the worker is pinched between the conveying support table that moves toward the delivery position and the new support member when the worker is about to place the article on the placement portion. Accordingly, an object of one aspect of the present invention is to provide an article conveying apparatus that stably holds an article at a placement portion that delivers the article to a conveying support table, and that reduces the possibility that a part of the body of an operator is pinched between the placement portion and the conveying support table. Technical means for solving the problems (1) An article transport device according to one aspect of the present invention is an article transport device for accessing an article to an apparatus for accessing the article, the article transport device including a placement unit for placing the article from outside the apparatus, an article transport mechanism for transporting the article between the placement unit and inside the apparatus, the article transport mechanism including a transport support table for supporting the article, a first movement unit for moving the transport support table back and forth between a first end and a second end, and a second movement unit for vertically lifting the transport support table, the placement unit including a first portion arranged on an extension line of a movement path of the transport support table, that is, in a first direction, a pair of second portions arranged so as to sandwich the first portion in a second direction orthogonal to the first direction in a plan view, and a slide mechanism for moving at least the first portion and the second portion between the first position when the first portion and the transport support table located at the first end are brought into contact with or close to each other, and when the first portion is located away from the transport support table along the extension line from the first position as a second position. The placement unit of the article transport device of this configuration is configured to support the article from three sides in the lower direction by a pair of second portions disposed so as to face each other in the second direction and a first portion disposed between the pair of second portions in the second direction, and therefore can stably hold the article. In addition, since at least a part of the placement unit having this configuration is provided so as to be movable from the first position toward the second position away from the transport support table along the extension line, even if a part of the body of the operator is sandwiched between the placement unit and the transport support table, the placement unit can be retracted toward the second position. This reduces the possibility that a part of the operator's body is pinched between the placement portion and the transport support table. (2) In the article transport device according to the above (1), each of the first portion and the pair of second portions may have a positioning pin fitted to the article placed on the placement unit. In this configuration, since the three parts are held in a state where the article is positioned at the predetermined position of the placement unit, the placement unit can stably and accurately hold the article. (3) In the article transport device according to the above (1) or (2
