Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article storage device attached to a clean room.

[0002]

2. Description of the Related Art Conventionally, in a clean room, an automated guided vehicle equipped with a battery is generally run. Therefore, it is necessary to periodically charge the battery, but it is a space-related problem to install a battery storage facility for this charging in a clean room. However, in order to prevent the generation of dust, it has been necessary to avoid moving the automated guided vehicle back and forth between inside and outside the clean room for that purpose.

[0003]

It is an object of the present invention to store and store articles such as batteries for charging in the clean room without causing space problems in the clean room. The purpose is to provide.

[0004]

In order to achieve the above object, the present invention employs the following means. That is, an article loading / unloading device for horizontally moving the article is provided above the floor surface in the clean room, and an article lifting device is provided toward the lower side of the article loading / unloading device. A plurality of stages of article storage shelves are provided along the left and right sides.

[0005]

The present invention has the following functions. Since the article lifting device (almost all of them) and the article storage shelves are arranged under the floor of the clean room, only the article loading / unloading device for the article lifting device needs to be provided in the clean room.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the embodiments shown in the drawings. In this specification, the right means the right side of FIG. 1, the left means the left side of the figure, and the front means the back side of FIG.
The rear is the same side. As shown in FIG. 1, with respect to a clean warehouse 2 provided inside a clean room 1, an article passing port 5 is opened at a lower part of a front wall 3 of its peripheral wall so that an article loading / unloading device 4 (see FIG. 2). The article lifting and lowering device 10 is provided below the article loading and unloading device 4, and a plurality of articles are provided on the left and right sides of the article lifting and lowering device 10 below the floor surface 1a of the clean room 1. Storage shelves 20, 20, ... Are provided.

As shown in FIG. 3, in the article elevating / lowering device 10, an elevating table 12 is vertically movable along a guide column 11 provided with an appropriate driving part (not shown). As shown in FIG. 4, a plurality of drive wheels 14, 14, ... Which are capable of rotating in the left-right direction in the transport direction are provided on the upper surface of the lifting table 12, and are connected to an article storage shelf 20 described later. The pallets 15 can be passed between each other.

As shown in FIG. 3, the article loading / unloading device 4 is
When the platform 12 of the article raising / lowering device 10 is at the uppermost position, the automated guided vehicle 2 is horizontally placed on the article passing port 5 and stopped.
The battery 21 installed inside the battery 3 is pulled down, and the battery 21 is horizontally moved as it is and transferred to the pallet 15 on the elevating table 12. Of course, the reverse operation is also performed. Therefore, the attraction electromagnet 7 for the battery 21 has a structure in which it can be slid back and forth while passing above the lift table 12 (pallet 15) by the slide fork 6. The slide fork 8 is composed of a fixed fork 6a and a plurality of movable forks 6b and 6c slidable with respect to each other.
In addition, the upper surface of the pallet 15 is formed by the free roller group 13 with the transport direction facing forward and backward.
In this embodiment, there is provided a transition roller board 9 which can be flipped up so as to straddle the lower edge portion of the article passage opening 5. The transfer roller board 9 is flipped up into a vertical posture or slid down into a horizontal posture by a shutter 8 which is vertically slidable so as to open and close the article passage opening 5.

As shown in FIG. 1, the article storage shelves 20 are arranged in a plurality of stages so as to face each other in the vertical direction with the guide columns 11, 11 of the article lifting device 10 sandwiched in the center. As shown in FIG. 4, the upper surface of the article storage shelf 20 has
Similar to the upper surface of the lifting table 12 in the article lifting device 10, a plurality of drive wheels 16, 16, ... Which are capable of rotating in the left-right direction and in which the carrying direction is left and right are provided. As shown in FIG. 3, a charging device 17 is installed in each of the article storage shelves 20 in front of the storage position of the battery 21. And an output line from the charging device 17 (not shown)
4 is wired and connected to a brush portion 19 that is urged to project against a pallet stopper 18 that is provided in a step shape at each of the left and right ends of the article storage shelf 20 as shown in FIG. The brush portion 19 conducts electricity to the pallet 15. Also,
Between the pallet 15 and the battery 21 placed on the top of the pallet 15, a brush portion 22 provided on the bottom surface of the battery 21 by downward urging is electrically pressed by being pressed against a printing plate 23 mounted on the pallet 15. It has become so.

[0010]

Next, the operation of the embodiment apparatus will be described.
When the battery 21 needs to be charged in the automatic guided vehicle 23, the automatic guided vehicle 23 is placed sideways on the article passage port 5 and stopped. Therefore, first, the shutter 8 is lowered to open the article passage port 5 and the crossover roller board 9 is placed in a horizontal posture. Then, the slide fork 6 and the electromagnet 7 of the article loading / unloading device 4 are operated to pull down the battery 21 in the automatic guided vehicle 23, and then the battery 21
Are transferred to the pallet 15 on the lifting table 12 in the standby state. Here, it is preferable to immediately raise the shutter 8 and close the article passage port 5. Next, the article elevating device 10 is operated to stop the elevating table 12 at the same height as the empty article storage rack 20. After that, the drive wheel 1 of the lift 12
4, 14, ..., Corresponding drive wheels 1 of the article storage rack 20
6 and 16 are rotated to store the battery 21, and at the same time, charging of the battery 21 is started. At this time, if the fully charged battery 21 is stored in the other article storage rack 20, the article elevating device 10 is operated to move the elevating table 12 up and down to the corresponding height position, and the battery 2
1 is received with the pallet 15 and returns to the uppermost position. Then, by operating the article loading / unloading device 4 and the like in the opposite manner, the battery 21 after charging is completed is mounted on the automatic guided vehicle 23.

In this embodiment, since the portion where the article passage port 5 is opened is the lower portion of the front wall 3 of the peripheral wall of the clean warehouse 2, the following advantages can be obtained. That is,
The above-mentioned portion in the clean warehouse 2 corresponds to the lower part of the entrance or exit port 24 of the article for storage, as shown in FIG. The loading or unloading port 24 is provided with a certain height so that the article transfer robot 25 installed on the upper part of the automatic guided vehicle 23 can be conveniently used for article transfer work. In the conventional case, the lower part thereof is practically a dead space. That is, as in this embodiment, if the article passing port 5 is opened below the front wall 3 of the peripheral wall of the clean warehouse 2 and the article loading / unloading device 4 is provided below the clean warehouse 2, dead space is reduced. Effective use will be achieved. However, the present invention is not limited to the above.

[0012]

The present invention has the above-mentioned structure.
The following effects are achieved. It has become possible to carry out articles in and out of a clean room when storing articles such as batteries for charging without causing a space problem. Of course, the generation of dust accompanying these operations can be suppressed as much as possible.
