[Problems to be Solved by the Invention] The conventional industrial robot traveling platform was constructed as described above, and the treadle 5 simply covered the linear guide 2 from above, so foreign objects and dust could come from diagonally above the linear guide. It was not possible to prevent the particles from falling onto and adhering to No. 2. In addition, since the cable carrier 15 is arranged adjacent to the side of the traveling base 6, the width of the entire traveling base increases, which increases the dead space and narrows the work area on the side of the robot 7. there were. Similarly, since the drive device 10 is installed on the traveling base 6, there is a problem that the work area in the moving direction becomes narrow. Furthermore, since the cable 14 of the robot 7 is exposed, there is a problem that the design cannot be improved.

The present invention has been made in view of the above, and an object of the present invention is to provide a running platform for an industrial robot that can improve the dustproofness of the linear guide, expand the working area, and improve the design.

[0008]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a linear guide base mounted on the support of the base, and linear guides mounted on both sides of the lower part of the linear guide base. , a linear guide cover attached to both sides of the linear guide base to prevent foreign matter from adhering to the linear guide, and a roughly inverted concave shape equipped with a robot loosely fitted to the linear guide base and guided by the linear guide. A traveling base, a drive device that rotates a pinion attached to one side of the lower part of the traveling base and meshes with a rack of the base to travel and move the traveling base, and a notch cut out in the traveling base and storing a robot cable. and,
The present invention is characterized in that it includes a cable bear that is disposed on the base, is located below the traveling base, and operates in conjunction with the traveling movement of the traveling base.

[0009]

According to the present invention, the linear guide is attached to both sides of the lower part of the linear guide base, and the linear guide is covered by the linear guide cover, so that the linear guide can be significantly dust-proofed. In addition, since the drive device and cable track are located between the base and the traveling base,
It is possible to expand the work area. Furthermore, since the robot cable is housed in the cutout of the travel base, the design can be improved.

Reference numeral 6 denotes a traveling base on which a robot 7 for servicing a large number of machines is mounted.As shown in FIG. 1, this traveling base 6 is constructed in a substantially inverted concave shape (horizontal C-shape) from the front, unlike the conventional example. It is loosely fitted into the linear guide base 17, and fitting portions 9 that fit into the linear guide 2 directly above are attached to both sides of the inner lower surface.

Reference numeral 10 denotes a drive device mounted on one side of the lower surface of the traveling base 6, and as shown in FIG.
It includes a motor 11 and a reducer 12 that operates based on the drive of the motor 11, and a pinion 13 that meshes with the rack 3 is fitted onto the rotating shaft of the reducer 12.

Reference numeral 20 denotes a notch cut out on the other side at the rear of the traveling base 6. In this notch 20, the cable 14 of the robot 7 is housed and protected.
4 is covered with a cover 21. Reference numeral 15 denotes a cable bearer disposed on the other side of the upper surface of the base 1. This cable bearer 15 is located below the other side of the lower surface of the traveling base 6, and stores and protects the cable 14 of the robot 7. It operates and moves in conjunction with the traveling movement of the base 6.

Therefore, when the motor 11 of the drive device 10 is driven, the reducer 12 operates to rotate the pinion 13 that meshes with the rack 3, and the traveling base 6 on which the robot 7 is mounted moves along the linear guide 2 of the linear guide base 17.・Run and move while being guided by 2. Additionally, a cable carrier 15 that protects the cable 14 in conjunction with the traveling movement of the traveling base 6 is provided.

Further, according to the above structure, the linear guide base 17 covers the upper part of the linear guide 2 to prevent dust, and the linear guide cover 19 prevents foreign matter from adhering to the linear guide 2 from the side. The dustproof properties of the guide 2 can be greatly improved. Note that although the bottom of the linear guide 2 is not covered with a cover, foreign matter and dust usually fall from above, so this does not cause any particular problem. Further, a drive device 10 is installed at one side of the lower part of the traveling base 6, and a cable carrier 15 is installed between the base 1 and the traveling base 6.
1 and 4, it is possible to narrow the width of the carriage and the dimensions in the direction of movement, thereby expanding the work area. Furthermore, the cable 14 is stored and protected in the notch 20 of the travel base 6,
Moreover, since the cable 14 is covered from the outside by the cover 21, the amount of exposed cable 14 can be minimized.
It becomes possible to significantly improve the design quality.
