DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable and hose guide and support device, and more particularly to a cable and hose for safely and movably connecting cables and hoses connected to moving parts of a machine tool, a robot, and a transfer device. The present invention relates to a cable and hose guide and support device for carrying out the above.

[0002]

2. Description of the Related Art In order to guide and support a cable or a hose that moves together with the above-described moving part, a plurality of frame-shaped links having a passage for a cable and a hose are connected in order, and each of the links is connected to each of the links. A guide has been proposed which extends each link at a link between the links) so as to bend or bend freely. FIG. 3 is a diagram illustrating an example of the configuration and movement of the guide 100. The guide 100 including a plurality of links has one end extending to the fixed portion 102 of the guide channel 101 and the other end extending from the fixed portion 102 and warping in a U-turn shape. In this state, it is fixed to the mounting part of the moving part 103. The moving unit 103 reciprocates in one axis direction, that is, in the horizontal direction as viewed in the drawing, with the operation of the apparatus, and accordingly, the guide 100 having one end fixed to the moving unit 103 is pulled by the moving unit 103, and From the solid line position to the broken line position (or from the broken line position to the solid line position) while moving the warped position sequentially to the next node
Moving. Guide 100 cables and hoses
And is supported in a protected manner from the outside by the frame. Guide 100
The guide channel 101 which supports from below has a substantially U-shaped cross section.
It has a floor portion 101A extending in the moving direction of the moving portion 103 and a pair of side walls 101B formed on both sides thereof, and the guide 100 is provided between the side walls 101b. Is guided along the floor 101A.

[0003]

The guide 10
0 has a configuration in which a plurality of links are connected as described above, so that the maximum bending (refractive) rate is limited due to the degree of freedom of link and link movement. Therefore, as shown in FIG. The warped portion requires a certain degree of curvature, and therefore, the mounting position of the guide 100 of the moving portion 103 is relatively high with respect to the fixed portion 102. Therefore, when the guide 100 moves between the solid line position and the broken line position with the reciprocating movement of the moving unit 103, the moving unit 10 of the guide
In the bent portion A near the mounting position of No. 3, the direction of the force acting on the solid line position and the broken line position is reversed, and the direction of the warpage is extremely reversed. Such a state does not cause a serious problem when the moving speed of the moving unit 103 (accordingly, the guide 100) is low. However, when the moving unit 103 (accordingly, the guide 100) reciprocates at a high speed, a bent portion is formed. Since the loads having different directions are repeatedly and concentratedly applied to A, the portion may be damaged or broken.

In order to solve this problem, as shown in FIG. 4, the mounting position of the guide of the moving part 103 is lowered, that is,
What is necessary is just to approach the floor of the guide channel 101, but in this case, when the moving part moves to the front position (the left position in FIG. 4), the part of the guide after warping downwards, In other words, a relatively long margin is required for mounting the guide in order to bend in the opposite direction, so that there is a problem that the total length of the guide channel is also increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has no risk of breakage or the like even in a relatively high-speed reciprocating motion, and furthermore, a cable / hose guide with a minimum length of a guide mounting portion. It is an object to provide a support device with a simple configuration.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention aims to guide and support a cable or a hose which is connected to a moving part which reciprocates in one axial direction and moves with the movement of the moving part. A guide for guiding the cable or hose, and a guide channel extending in the uniaxial direction for supporting the guide from below, wherein the guide has a plurality of guides. The link is configured to bend or bend freely at each node, and one end of the link is fixed to the fixed portion of the guide channel and the other end is fixed to the moving portion, and the link is bent back and forth with the reciprocating movement of the moving portion. The guide channel is configured such that a floor portion supporting a front portion of the guide when the guide moves forward is inclined downward. And butterflies.

More particularly, each of the links is formed of a frame which forms a continuous passage for guiding a cable or a hose.

[0008]

According to the above means, when the moving portion moves forward, the front portion of the guide sinks downward according to the inclined guide channel. Does not need, therefore
In a state where the extra length of the mounting portion is minimized, the position of the mounting portion can be made lower than before, so that the concentration of the load on the bent portion A near the mounting portion of the moving portion is eliminated,
Higher speed movement becomes possible.

[0009]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIGS. 1 and 2 show an example of a cable / hose guide / support apparatus according to the present invention. As shown in the drawings, a guide 1 is formed in a chain that can be bent or bent at each node, and a guide that supports the guide 1 from below. Channel 2. The guide 1 and the guide channel 2 are provided along the traveling path at a position below the traveling path of the moving unit 3 such as a machine tool to be connected.

The moving section 3 reciprocates in one axis direction, that is, in the horizontal direction as viewed in the drawing, during operation of the machine, and one end of the guide 1 is fixed to the mounting section of the moving section 3. The other end of the guide 1 is fixed to a fixed portion of the guide channel 2, and a plurality of cables and hoses drawn from a supply unit (not shown) are guided and supported through the passage of the guide 1. It is guided from the fixed part side to the moving part 3 side.

The guide 1 has a plurality of links 11 made of plastic or metal. Each of these links has a structure in which each link with the adjacent link 11 is connected in a bendable or bendable manner in a chain shape, and one end is fixed to the fixed portion of the guide channel 2 and the other end is the moving portion 3 as described above. It is fixed in a warped state. 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 state where the guide 1 warps with the reciprocation of the moving unit 3.

As specifically shown in FIG. 2, each link 11
Continuous path 1 for guiding cables or hoses
1a is formed in the shape of a hollow box-shaped frame body, and each link is provided with a side wall rotatable by a pair of pivots 11b with respect to an adjacent link. At the node of the link, it is bendable or bendable on substantially the same plane (a plane parallel to the paper surface in FIG. 1). 2 (2), the upper stay 11c of each link 11 is openable / detachable or detachable. By opening or removing the upper stay 11c, a cable or a hose can be disposed in the passage 11a from above. . When the upper stay 11c is closed, it is temporarily fixed by a suitable locking means such as a clamp.
