Description

[Detailed description of the invention] The present invention is a mobile storage device, more specifically, a plurality of carts with wheels that move on an endless track are placed on an endless track, and the carts are moved in a circular manner by a drive device. Regarding such a mobile storage device, the object is to provide a mobile storage device that can extremely smoothly store and take out stored items on the cart, and that can efficiently load stored items onto the cart. There is something to do.

Traditionally, a platform has been installed on an endless track so that it can move freely.
Various mobile storage devices have been developed in which the cart is circulated by a drive device, but all of them are equipped with racks partitioned into multiple stages, and for example, stored items are stored in the upper part of the rack. In this case, it is necessary to use a lifting device such as a forklift, and as a whole, it is extremely inconvenient to load and unload stored items onto the cart.

Accordingly, the present invention provides a circulation device in which a plurality of suspension bodies for stored objects are provided on a plurality of carts that circulate on an endless track, and while the circulation device is sequentially circulated, the suspension bodies are The above-mentioned problems are solved by making it possible to suspend the stored items as appropriate, and in addition, when driving the circulation device of each bogie, there is no need to provide a drive machine for each circulation device. A drive machine installed at the loading/unloading position of the stored items and below the trolley that stops at the position can drive each of the circulation devices while moving the stored items to the loading/unloading position. The movable storage device of the present invention is devised in such a way that the circulation device of the stopped cart can be immediately linked to the driving machine.The movable storage device of the present invention will be described below with reference to the embodiment shown in the drawings.

The rails 40 are pivotally supported so as to be freely rotatable.

At the free end of the one connecting piece 45a,
The holding body 47 is attached to freely swing, and the suspension body 5 made of a cylindrical pipe material is installed on the holding body 47, and hangers H, H, etc., on which clothes are hung, for example, are hung on the suspension body 5. It is.

Further, a worm reducer 61 is installed on one side wall of the truck 2.
is provided, and one of the drive shafts 43b is connected to the reduction gear 6.
A drive shaft 62 connected to the drive shaft 1 and extending from the speed reducer 61 is extended to the lower part of the lower surface of the truck 2, and a driven body 63 such as a friction plate (hereinafter referred to as a mass plate) is attached to the end of the drive shaft 62. , these worm reducer 61, drive shaft 62, and mass plate 63 constitute a driven mechanism that rotationally drives the rotating body 41b, while the endless track 12
The endless track 12 is placed on the base 10 on which the endless track 12 is installed.
The drive unit 64, which can be engaged with the driven body 63, is moved by the pedal 65 at the loading/unloading position of the stored items provided at one location around the storage area and below the trolley 2 that stops at the position. A desired trolley 2 is installed so that it can be raised and lowered through the
When the drive unit 6 is stopped, the pedal 65 causes the drive unit 6 to stop.

When, for example, clothes or the like is to be stored in the carts 2, 2..., one of the carts 2 is first stopped at the place where the drive machine 64 is installed. Clothes and the like are suspended via hangers H on an arbitrary suspension body 5 located below the front side of the trolley 2.

After that, depress the pedal 65 to lift up the drive unit 64, and then lift the drive unit 64 by pressing the foot plate 66 on the side of the drive unit 64.
is brought into pressure contact with the mass plate 63 on the side of the drive shaft 62, and the driving force of the drive machine 64 is transmitted from the drive shaft 62 to the rotary body 41b via the reduction gear 61, whereby the endless band 42
While the suspension bodies 5, 5, .

As described above, the other trolleys are also moved to the loading and unloading positions of the stored items, and clothing and the like are stored as appropriate in the same procedure as described above.

Further, the same applies when carrying out stored items such as clothes stored in the carts 2, 2, . . . .

Further, in the embodiment, the driving machine 64 and the drive shaft 62 are provided with mounting plates 66 and 63, respectively, and the driving machine 64 is interlocked and connected to the drive shaft 62 via these mounting boards 66 and 63. However, the drive machine 64 may be connected to the drive shaft 62 by any other connection means.

As described above, the present invention provides a circulation device in which a plurality of suspension bodies for stored objects are provided on a plurality of carts circulating in an endless track, and while the circulation device is sequentially circulated, Since the stored items are to be suspended, when loading or unloading the stored items onto or from the cart, the circulation device provided on each of the carts is driven by circulation to move the desired suspended body to a height position where the stored items can be loaded/unloaded. You can move the
It is possible to immediately suspend the stored items on a desired suspension body or take them out at the loading/unloading position of the stored items without using a special elevating device. A driven mechanism for rotationally driving a rotating body of the device is provided, and a drive machine capable of engaging with the driven body is provided at a location around the endless track at a loading/unloading position of the stored item, and The driving machine is installed to be located below the trolley that stops at the position, and the driving machine is interlocked and connected with the driven body of the circulation device of the trolley that stops at the position, and the circulation system of each of the trolleys is driven by the driving machine. Since it is designed to be circularly driven, it is possible to drive the circulation device in each of the carts with one drive machine without providing a drive device for the circulation device for each cart, and it is possible to carry out the desired loading or unloading. When the trolley is stopped at the loading/unloading position of stored items, the driven body of the circulation system in the trolley and the driving machine can be linked to each other, and as a result, the driven body and the driving machine can be connected to each other. The interlocking connection with the machine can be made immediately after the trolley has stopped.

Furthermore, since each of the bogies circulates not on a straight track but on an endless track, when the circulation device of each bogie is driven by one drive machine, the length of the endless track is made especially long. There is no need to do so.
