Description

  The present invention relates to a rail for guiding a cable carrier and the like and a mounting structure thereof.

  In the case where a cable bear or the like is used for wiring of the moving body, it is known to provide a space for receiving the cable bear (Patent Document 1: Japanese Patent Application Laid-Open No. 07-157010). FIG. 4 shows a conventional example in which a cable bearer is accommodated in a guide rail. Reference numeral 40 denotes a guide rail body, which is welded to a flat mounting plate 41 by spot welding or the like at a welding portion 42 and fixed to the sleepers 4 with bolts 9 via a mounting tool 43.

By the way, the inventor has found that the guide rail of FIG. 4 is likely to cause dust generation because foreign matter tends to accumulate in the gap between the guide rail body 40 and the mounting plate 41. When the guide rail body 40 and the mounting plate 41 are welded, a slight gap remains in a portion other than the welded portion 42, and foreign matter tends to accumulate in this portion. As a specific example, when the guide rail was acid cleaned after welding, the acid cleaning solvent remained in the gap and leaked from the gap after about one year had passed. In addition, if even a slight gap remains, there is a possibility that the guide rail will rust from the gap when condensation occurs, and rust may leak from the gap. Therefore, the inventor studied the guide rail in which no foreign matter is generated from the gap between the guide rail main body 40 and the mounting plate 41 and arrived at the present invention.

SUMMARY OF THE INVENTION An object of the present invention is to provide a guide rail that does not have a gap that causes generation of foreign matters and that can be easily mounted, and a mounting structure thereof.
An additional object of the present invention is to facilitate entry / exit of a cable to / from the guide rail.

The guide rail according to the present invention includes a bottom portion on which the cable is placed, and both left and right walls of the bottom portion. And an upright portion that is upright when viewed from the bottom.
Preferably, an introduction portion that is inclined outward in the left-right direction when viewed from the bottom portion is provided integrally with both walls at the top of both walls.

  In the guide rail mounting structure of the present invention, in order to fix the guide rail for housing the cable to the ground side, the guide rail includes a bottom portion on which the cable is placed, and both walls provided on the left and right sides of the bottom portion. In each case, the bottom part is inclined to the center in the left-right direction and an inclined part integrated with both walls is provided, and the horizontal part of the fixture having a horizontal part and a contact part is fixed to the ground side. By bringing the contact portion into contact with the inclined portion of the guide rail, the guide rail is fixed to the ground side.

In the present invention, the guide rail body can be fixed to the ground side without a separate mounting plate by bringing the fixture into contact with the inclined portion between the bottom and both walls. For this reason, welding between the guide rail body and the mounting plate is unnecessary, and there is no gap between them, so that no foreign matter accumulates in the gap. The guide rail can be manufactured by bending a single plate or extruding a material.
Here, when the introduction part inclined to the outside in the left-right direction when viewed from the bottom part is provided at the top of both walls, cables such as wiring and cable bears are adjusted in direction and position at the introduction part and enter into both walls. Cable entry and exit is smooth.

  In the following, an optimum embodiment for carrying out the present invention will be shown.

  1 to 3 show a guide rail 2 of the embodiment and its mounting structure. In the figure, reference numeral 4 denotes a sleeper, which is arbitrary as long as it is a member fixed to the ground side and receiving the guide rail 2. Reference numeral 6 denotes an attachment, which includes an inclined contact portion 7 and a horizontal portion 8 and is attached to the sleeper 4 with a fastener such as a bolt 9. The guide rail 2 has a horizontal bottom 10, an inclined portion 12 that rises inclining from the left and right sides toward the inner side in the left-right direction, an upright portion 14 that extends substantially vertically upward from the inclined portion 12, and an upright portion 14. And an introduction portion 16 located above. The guide rail 2 is composed of a single plate and is made of metal, for example, but may be plastic or the like.

  The inclination angle α of the inclined portion 12 with respect to the bottom portion 10 is, for example, 60 to 80 °, and generally 45 to 85 °. The upright portion 14 corresponds to both walls of the guide rail 2, and the introduction portion 16 extends from the upper end of the upright portion 14 to the outside in the left-right direction of the bottom portion 10, and guides the entrance and exit of cables such as the cable bear 20. The cable bearer 20 in the guide rail 2 is indicated by a chain line, and the cable bearer 20 is folded up and down in the guide rail 2 to be divided into an upper stage 21 and a lower stage 22.

  When the guide rail 2 of the embodiment is manufactured, a single plate is bent by sheet metal processing or the like, or a material such as metal or plastic is formed by extrusion. Then, the contact portion 7 of the fixture 6 is brought into contact with the outer inclined surface of the inclined portion 12 of the guide rail 2, and the guide rail 2 is fixed with a bolt 9 or the like. Then, the guide rail 2 is fixed on the sleepers 4 by the pressure from the contact portion 7.

  The guide rail 2 is used to accommodate cables in various carts such as a stacker crane and a tracked cart and a moving body. The sleepers 4 can also be used to support the carriages and the traveling rails of the moving body. The cable bear 20 has one end fixed and the other end attached to a carriage or a moving body, and is used for power supply or signal exchange. As the carriage or moving body moves, the folding position of the cable bear 20 changes, and as shown on the right side of FIG. 2, the cable bear 20 is pulled out from the guide rail 2 and connected to a not-shown moving body or carriage. The

  The cable bear 20 is placed on the bottom portion 10, and the position in the left-right direction is restricted by the upright portion 14, and the guide bear 2 enters and exits while the direction and the position and direction in the left-right direction are restricted by the introduction portion 16. Therefore, the guide rail 2 can smoothly guide the movement of the cable bear 20.

In the embodiment, the following effects can be obtained.
(1) The guide rail 2 can be constructed from a single plate or material. Therefore, it is not necessary to weld the guide rail body and the mounting plate as shown in FIG.
(2) Since there is no gap between the guide rail body and the mounting plate, foreign matter accumulates in the gap and does not cause dust generation.
(3) The guide rail 2 can be easily fixed to the sleepers 4 or the like by the fixture 6 using the inclined portion 12.
(4) The introduction part 16 can smoothly guide the cable bearer 20 in and out.
