BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling support having a support surface on which a pair of guide rails arranged in parallel and a rack extending between the guide rails and extending in the same direction as the guide rails are disposed. And a pinion shaft that rotates substantially on the rack of the traveling support to move in parallel with the guide rail, and one or more sliders that slide on the guide rails as the pinion shaft moves in parallel. And a robot main body having a moving surface having a moving surface, and particularly for protecting the supporting surface when the robot main body moves along the supporting surface of the traveling support. The aim is to fix the rail cover in a space-saving manner regardless of the movement of the robot body.

2. Description of the Related Art A conventional parallel moving device is shown in FIG.
There is a wall-mounted horizontal movement device as shown in Fig.
The pinion shaft arranged on the moving surface of the robot body is rotated by a drive motor built into the robot body to move substantially horizontally on the rack provided on the support surface of the traveling support, and with this movement, By sliding the slider arranged on the moving surface on the guide rail, the robot main body can be stably moved horizontally.

In such a moving device, the pinion shaft and slider provided on the moving surface of the robot body are respectively
Since the structure is such that the rack and the guide rail provided on the support surface of the traveling support work together, the supporting surface of the traveling support is
Generally, it is either exposed as is, or protected by a bellows-type collapsible cover.

[0004]

However, when the support surface of the traveling support is exposed, undesired substances such as dust tend to adhere, which causes the movement of the robot body. However, if the supporting surface of the running support is protected by a bellows-type foldable cover,
Since the robot body is repeatedly folded along with the movement of the robot body, it has a drawback that it is easily fatigued and damaged, and it is aesthetically unfavorable. Further, it is conceivable to cover the entire parallel moving device, but this is not preferable because it requires a large space and becomes a large scale. Therefore, it has been necessary to develop a means that can protect the support surface of the traveling support stably regardless of movement of the robot body without taking up space.

Therefore, an object of the present invention is to provide a rail cover for protecting the supporting surface of the traveling support when the robot body moves along the supporting surface of the traveling support, regardless of the movement of the robot body. The object of the present invention is to provide a parallel movement device that can be fixedly arranged in the.

[0006]

In order to achieve the above object, a parallel moving device of the present invention comprises a pair of parallel-arranged guide rails, and a single strip extending between the guide rails and extending in the same direction as the guide rails. A traveling support having a support surface on which a rack is disposed, a pinion shaft that rotates on the rack of the traveling support and moves substantially in parallel to the guide rails, and the parallel movements of the pinion shaft A robot main body having a moving surface on which one or more sliders respectively sliding on the guide rails are arranged, and the traveling support has one end fixed to the supporting surface between the rack and each guide rail. A pair of support plates extending in an orthogonal direction to each other, and a pair of cover plates fixed to the other end of the support plate and arranged to face the supporting surfaces, respectively. It is fixed to the moving surface of the robot body via a spacer member having a middle groove wider than the thickness of the cover plate of the support, and the spacer members located on different guide rails are arranged so that the middle grooves face each other and the traveling support is performed. Place the cover plate of the body between the position directly above the pinion shaft of the robot body and the middle groove position of the upper spacer member,
And between the position directly below the pinion shaft and the position of the middle groove of the lower spacer member. In addition, it is preferable in practice that the traveling support further has an auxiliary cover extending in a direction orthogonal to the support surface on at least one of the upper end and the lower end of the support surface.

[0007]

In the parallel moving device of the present invention, the slider provided on the moving surface of the robot body is fixed to the moving surface via the spacer member, thereby providing a space between the slider and the moving surface, and the space is provided in this space. By arranging so that the cover plate provided on the support surface of the traveling support is positioned,
It is possible to always stably protect the support surface of the traveling support regardless of the movement of the robot body. Moreover, the cover plate can be provided in a small space between the slider and the moving surface. Further, unlike the conventional bellows-type protective cover, the protective cover is not repeatedly folded, so that the protective cover is not damaged. In addition, at least one of the upper end and the lower end of the support surface of the traveling support has the auxiliary cover extending in the direction orthogonal to the support surface, so that the supporting surface of the traveling support can be covered more effectively.

And a slider 13 having one or more sliders 12 that slide on the guide rails 4a or 4b as the pinion shaft 11 moves horizontally.

The movement of the pinion shaft 11 is preferably performed, for example, by using an electric motor built in the robot body 3 as a drive source.

The slider 12 provided on the robot body 3 preferably has a bearing mechanism on its sliding surface. 1 and 3, the sliders 12 are provided on the guide rails 4a and 4b, two sliders are provided on each of the guide rails 4a and 4b.
It is sufficient that the number is equal to or larger than the number, and it is possible to appropriately change the number to be arranged as necessary.
