Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable / hose guide and support device, and more particularly, to a cable and hose connected to a moving part of a machine tool, robot, transfer device or the like so as to be safely and movably protected. The present invention relates to a guide support device for a cable / hose.

[0002]

2. Description of the Related Art In order to guide and support a cable or a hose that moves together with a moving part as described above, a plurality of frame-shaped links each having a passage for a cable and a hose therein are connected in order, and each node ( An extending guide has been proposed in which each link is bendable or bendable at a link (link connecting portion). FIG. 3 is a diagram for explaining the configuration and movement of an example thereof, and a guide 100 composed of a plurality of links has one end extended to the fixed portion 102 of the guide channel 101 and the other end extended from the fixed portion 102 to be bent back in a U-turn shape. In this state, the moving part 103 is fixed to the mounting part. The moving unit 103 reciprocates in one axis direction, that is, in the horizontal direction as seen in the drawing as the apparatus operates, and accordingly, the guide 100 having one end fixed to the moving unit 103 is pulled by the moving unit 103, From the position of the solid line to the position of the broken line (or from the position of the broken line to the position of the solid line) while moving the curving position in order to the next node.
Moving. Guide 100 for cables and hoses to guide
Is guided through a passage in the frame and is supported by the frame in a state of being protected from the outside. Also, the guide 100
The guide channel 101 for supporting the upper part from below has a substantially U-shaped cross section.
The guide 100 has a floor portion 101A that extends in the moving direction of the moving portion 103 and a pair of side walls 101B that are formed on both sides of the floor portion 101A. Is guided along the floor 101A.

[0003]

By the way, the guide 10
Since 0 has a structure in which a plurality of links are connected as described above, the maximum bending (refraction) rate is limited due to the freedom of movement of the links, and therefore, as shown in FIG. The curving portion requires a certain degree of curvature, and therefore, the mounting position of the guide 100 of the moving portion 103 is at a high position relatively distant from the fixed portion 102. Therefore, when the guide 100 moves between the solid line position and the broken line position as the moving unit 103 reciprocates, the moving unit 10 of the guide moves.
In the curved portion A near the mounting position of 3, the direction of the force acting on it is reversed at the solid line position and the broken line position, and the direction of the warp is extremely reversed. Such a state does not cause a big problem when the moving speed of the moving part 103 (hence, the guide 100) is slow, but when the moving part 103 (hence, the guide 100) is reciprocated at a high speed, a curved portion is generated. Since the load having different directions is alternately and repeatedly concentrated on A, the portion may be damaged or broken.

In order to solve this, as shown in FIG. 4, the mounting position of the guide of the moving portion 103 is lowered, that is,
It suffices to bring it closer to the floor of the guide channel 101, but in this case, when the moving part moves to the front position (the left position as viewed in FIG. 4), the part of the guide that is bent back is below, That is, since the guides are bent in the opposite direction, a considerably long margin length is required for mounting the guides, which causes a problem that the total length of the guide channels becomes long.

The present invention has been made in view of the above point, and there is no fear of damage even when reciprocating at a relatively high speed, and the cable / hose guide having the minimum margin length of the guide mounting portion is minimized. An object is to provide a supporting device with a simple structure.

[0006]

In order to solve the above problems, the present invention is for guiding and supporting a cable or a hose which is connected to a moving part which reciprocates in one axial direction and which moves with the movement of the moving part. In the cable / hose guide supporting device, there is provided a guide for guiding the cable or the hose, and a guide channel extending in the uniaxial direction for supporting the guide from below, and the guide includes a plurality of guide channels. The links are connected flexibly or flexibly at each node, and one end of the link is fixed to the fixed part of the guide channel and the other end is fixed to the moving part, and the link is bent back and forth as the moving part reciprocates. The guide channel is such that the floor supporting the front portion of the guide is inclined downward when the guide is moved forward. And butterflies.

Further, in particular, each of the links is characterized by a frame body which forms a continuous passage for guiding a cable or a hose.

[0008]

With the above-mentioned means, when the moving portion moves forward, the front portion of the guide sinks downward along the inclined guide channel, so that the bending portion in the opposite direction of the guide mounting portion as described above is formed. Not needed, so
The position of the mounting portion can be made lower than before with the margin length of the mounting portion being minimized, which eliminates the concentration of load on the curved portion A near the mounting portion of the moving portion.
Higher speed movement is possible.

The guide 1 has a plurality of links 11 made of plastic or metal. Each of these links has a structure in which each connecting node with an adjacent link 11 is connected in a chain shape so as to be bendable or bendable, and has one end fixed to the fixed part of the guide channel 2 and the other end moved to the moving part 3 as described above. It is fixed in a state where it is bent back. As a result, the guide 1 moves in the front-rear direction, that is, from the solid line position to the broken line position (or from the broken line position to the solid line position) in a warped state as the moving section 3 reciprocates.

As shown particularly in FIG. 2, each link 11 is
A continuous passageway 1 for guiding cables or hoses
1a is formed in the shape of a hollow box-shaped frame body, and each link has its side wall pivotally provided by a pair of pivot shafts 11b with respect to adjacent links. In the link node, it can be bent or bent on substantially the same plane (a plane parallel to the paper surface in FIG. 1). As shown in FIG. 2 (2), the upper stay 11c of each link 11 can be opened / closed or detached. By opening or removing the upper stay 11c, a cable or a hose can be arranged in the passage 11a from above. . When the upper stay 11c is closed, it is temporarily fixed by an appropriate locking means such as a clamp.

On the other hand, the guide channel 2 has a substantially U-shaped cross section arranged so as to extend along the uniaxial direction, that is, the reciprocating direction of the moving portion 3.
