The frontage bar code 52 includes, for example, a bar code to which the location ID of the frontage 44 is assigned, a classification before and after the shelf 42, a frontage number (stage number, column number), and the like. The identification information of the frontage barcode 52 is read by the handy terminal 71 and transmitted to the wireless communication unit 72 of the control device 70.

Furthermore, a movable partition plate 55 (an example of a “partition body”) is disposed at each of the front openings 44. The movable partition plate 55 is formed of, for example, a vinyl chloride sheet, and includes a placement portion 56 for placing the product W and a partition portion 57 that partitions the frontage 44.
As shown in FIGS. 2 and 3, the placement portion 56 is formed of a plate-like member on which the product W can be placed. One end portion 56A of the mounting portion 56 is formed in a concave shape when viewed from the side. One end portion 56 </ b> A of the mounting portion 56 can be fitted to the stepped portion 50 (cover 51) of the shelf board 47 and can slide with respect to the stepped portion 50 of the shelf board 47. A front-end barcode 52 for identifying the location of the front-end 44 is affixed to one end 56 </ b> A of the placement unit 56.
The partition portion 57 is a plate-like member that is formed perpendicular to one side surface (right side surface) of the placement portion 56.

As shown in FIG. 2, the movable partition plate 55 moves in the left-right direction of the frontage 44 by sliding one end portion 56 </ b> A of the placement portion 56 against the stepped portion 50 (cover 51) of the shelf plate 47. .
In the picking cart 40, when transporting fruits and vegetables (agricultural products) such as cabbage having a relatively wide width, the movable partition plate 55 is brought into contact with the vertical partition plate 48 on one side (right side) of the frontage 44 (contact). However, when transporting a refrigerated product or the like having a relatively narrow width, the movable partition plate 55 is moved to one side (left direction) and used. That is, by moving the movable partition plate 55 within the frontage 44, the width of each frontage 44 can be adjusted in accordance with the width of the product W to be conveyed, and the number of frontage 44 can be adjusted by moving the movable partition plate 55. Up to twice as much as before (in FIG. 2, the number of frontage 44 before movement is 36 (18 pieces / surface × front and rear two surfaces), whereas the number of frontage 44 after movement is 72 (36 / surface × front and rear 2). Surface)).

Further, as described above, the front-end barcode 52 is affixed to the one end portion 56 </ b> A of the placement portion 56 of the movable partition plate 55. Therefore, by moving the movable partition plate 55 in one direction (left direction), the front-end barcode 52 can be arranged with respect to the newly partitioned front-end 44.

  Furthermore, as shown in FIG. 4, the lowermost stage 42 </ b> A of the shelves 42 in the picking cart 40 can be formed by a single opening 44. The picking facility 10 not only processes relatively small goods W such as fruits and vegetables (agricultural products) or refrigerated goods, but also handles large boxes and the like (large goods W) containing drinking water, canned foods, and the like. Therefore, when such a large product W is transported by the picking cart 40, the large product W cannot be loaded on the shelf 42 at the opening 44. Further, since many large products W are relatively heavy, if such large products W are loaded on the upper stage of the shelf 42 in the picking cart 40, the center of gravity is biased to the upper portion of the picking cart 40, and the picking cart 40 is It may not be possible to move in a stable state. Therefore, by forming the lowermost stage 42A of the shelf 42 in the picking cart 40 with a single opening 44, the width of the opening 44 is widened and a large product W can be loaded. Further, by arranging the movable partition plate 55 in the single front opening 44, the number of front openings 44 and the width of the front openings 44 in the lowermost stage 42A of the shelf 42 can be adjusted.

Next, the control device 70 will be described.
