Thus, since the cart 2 can be driven in a coupled state with the cart 1, the picking cart can be used even in a place having only a narrow passage width.
[0020]
The picking cart according to the present invention that exhibits the advantages as described above can be configured as illustrated in FIGS. 6 to 8 and will be described below. 6-8, the same code | symbol as FIGS. 1-5 shall point out the same member and the same part.
[0021]
The picking cart of the present invention illustrated by FIGS. 1 to 5 is connected or coupled to the operating cart 2 in a manner in which the cart 1 is held in the traveling direction of the picking cart. In the example, the cart 1 is taken in and out from the side of the operating cart 2 and coupled and separated.
[0022]
That is, in the example of FIGS. 6 to 8, the lower frame 2a of the operating cart 2 is formed in a shape having an open side surface so as to form a substantially U shape when viewed from above, and the carriage 1 is a side surface of the frame. A connecting portion 1e, 2h that connects the cart 1 and the cart 2 when inserted into the frame of the cart 2 can be inserted into and removed from the frame of the operating cart 2 through the opening. Is formed between the side inner surface of the frame and the opposite surface of the carriage 1. The connecting parts 1e and 2h will be described later.
[0023]
In the cart body 2 shown in FIGS. 6 to 8, a support column 2b is erected on the front and rear of the lower frame 2a (with respect to the cart traveling direction), and the upper end side of the support column 2b is horizontally integrated with the support column 2b. The upper frame 2c and the handles 2d and 2e are formed so as to be bent. Note that the frame form of the cart body 2 including the handles 2d and 2e is not limited to the illustrated one. In short, it is sufficient that the cart 1 can be taken in and out of the cart main body 2 from the side of the cart main body 2 and the cart 1 is held in the frame of the cart main body 2 when the cart 1 is inserted. 6 to 8, the power source 5 of the operating information device 3 is disposed on the lower surface side of the upper frame 2c in the cart 2.
[0024]

【The invention's effect】
In conventional cart-type picking carts that extend the handle frame, etc., and operating carts and carts that connect operating carts and carts, the overall length is quite long, resulting in a dead end. It is not possible to swivel in the aisle, and when the picked article is put into the container, the worker is forced to walk 1 m to several meters or more, and the above conventional type picking cart stores the article. When the path formed between the shelves is narrow, it is difficult to turn, of course, it may be difficult to travel or may not be used at all.
[0028]
Therefore, in the present invention, the connectable and separable operating cart and the article loading cart are integrated with each holding an independent function, that is, the cart to be connected to the cart is already installed by the cart. Since it is formed so as to be held and connected, the picked article can be put into the container in the operating posture and in that position, and the overall size is the floor occupation area of the operating cart ( The plane projection outline is extremely compact because it is within the plane projection). Therefore, it is possible not only to travel even in a narrow passage, but also to turn, and even if it is not possible to turn, in the direction of travel of the operating cart There is no directionality, that is, it is possible to run from either the front or rear direction.
[0029]
Further, in the present invention, the picking information device can be operated and displayed from either the front or rear side of the operating cart regardless of the direction of the cart running direction, and the picked article can be displayed on the container. Since the loading can be performed on the spot without walking at all, it is necessary to walk about 1 to 3 m every time picking in order to put the picked article into the container in the work using the conventional picking cart. Therefore, it is possible to almost completely eliminate the difficulty that had an adverse effect on the picking work efficiency. In particular, the picking cart of the present invention enables the picking work in the above-described manner even in a place where a conventional size cart can not be carried in due to a narrow passage. Therefore, picking work efficiency and labor saving in such a place On the top, it has a great effect.
