At the distal end of the connecting arm 172, a pair of substantially arc-shaped joint fittings 174 are attached, respectively, and a pipe member of the casing 108 (a standing upright disposed on the near side in FIG. 7). (Pipe material) 104.

Normally, the worktable 102 is
The work plate 116 housed in the shelf 148 is sequentially pulled out and housed repeatedly to perform equipment assembling work. Thereby, a single work table can be used as a plurality of (seven in the present embodiment) different work plates 116,
Work space is reduced.

The operation of this embodiment will be described below.

First, the work plate 114 is stored on the shelf 148 of the shelf 142 of the stocker 100 with the work table 102 detached from the housing 108. In this case, the uppermost shelf 148 is opened.
At the time when the work plate 116 is accommodated in the uppermost shelf 148, the second upper shelf 14
8, the next work plate 116 is housed, and finally the work plate 116 is housed up to the lowest shelf 148. As described above, since all the positions for accommodating the work plate 116 are at the height position where the opening 114 is provided, the accommodating operation is simple and can be performed quickly.

When the storage of the work plate 116 is completed,
The worktable 102 is connected to the housing 108. In this operation, the work body 102 is transported on the work space, and
The joint fitting 174 at the tip of the second 2 is connected to the pipe member 104 of the housing 108. Thereby, the connection between the housing 108 and the worktable 102 is completed together with the positioning.

The operator operates the elevator 130 to remove the desired work plate 114. For example, when removing the work plate 116 placed on the uppermost shelf 148, the pantograph section is operated by the elevator 130. Move 134 to the lowest position. Thus, the uppermost shelf 148 is held in a state corresponding to the opening 114.

Next, the operator leans on to take out the work plate 116 from the inside of the housing 108. At this time, since the work plate mounting table 164 of the work table 102 is recessed in a substantially U-shape, there is little interference with the operator, and the hand 152 is easily inserted into the long hole 152 which is a grip provided on the work plate 116. Arrives.

The operator pulls the work plate 116 by hooking a finger or the like into the long hole 152. At this time, the opening 11
Roller 118 is attached to lower pipe material 104 forming
Is attached, and the work plate 116 is pulled out while riding on the roller 118. Therefore, the work plate 116 is smoothly drawn out without applying excessive force.

The extracted work plate 116 is mounted on the work plate mounting table 1 at substantially the same height as the opening 114.
The position is determined by being placed on the upper surface 64 and abutting against the stopper fitting 166.

The work plate 116 is covered with a cover 156.
Hang over. At this time, the state in which the cover 156 is leaned against the housing 108 by the magnetic force is maintained, so that the work surface of the work plate 116 can be exposed.
In this state, the worker performs assembling work of the equipment. However, since the pipe member 104 on the front side of the transport base 158 of the worktable 102 is slightly offset, a space for the feet is surely secured during the work. The work table 102 can be prevented from interfering with the work table 102 and swinging or falling down.

Since the instruction on the work plate 116 is affixed (or written) to the cover 156 leaning against the housing 108, the operator writes this instruction. The work contents can be confirmed by looking.

The parts and the like are housed in the box 150A, and the common tools are neatly housed in the tool case 168 on the side of the worktable 102, so that the working efficiency is high.

When a series of operations in accordance with the instruction are completed,
The operator puts the cover 156 on the surface of the work plate 116 and pushes the work plate 116 in the direction opposite to the direction of pulling out, that is, in the direction of the housing 108. By this pushing operation, the work plate 116 rides on the roller 118 and is stored as it is on the shelf 148 that was initially stored.

Next, the operator operates the elevator 130,
Next, in order to pull out the necessary work plate 116,
42 is moved up and down (in this case, since it was the uppermost stage, it is lowered). After that, the work plate 11 is
6 is pulled out and a predetermined operation is performed.

As described above, in the present embodiment,
A plurality of work plates 116 are housed in the shelf 142 in the housing 108 of the stocker 100 in advance, and the desired work plate 116 is pulled out of the housing 1 by an elevator.
08, and the worktable 102
Can be pulled out onto the work plate mounting table 164, so that a plurality of works can be performed on the single work table 102, and a plurality of work plates 116 corresponding to the plurality of works can be stored on the shelf 142. A plurality of stages can be stored. Thereby, the working space can be made extremely small.

The worktable 102 can be easily removed from the housing 108, can be moved in the work space by the worktable 102 alone, and can easily cope with a change in work process. Therefore, the work efficiency when the work process is changed is improved.

In the present embodiment, the pipe member 104 is used as the framework. However, the material is not limited to a square pipe, an L-shaped or H-shaped steel member as long as it has a predetermined rigidity. Further, for example, although the housing 108 is only a frame, a panel may be attached after the frame so that the inside may not be seen. In this case, dust can be prevented from entering. In addition, the shelf 142 is configured to be lifted from below as an elevator, but the shelf may be held in a suspended state and moved up and down. In this case, for example, like an elevator,
It is preferable to provide a balancer.
