Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support structure for an electric wire and / or a fluid hose that is installed between a main body of the machine and a revolving structure of a machine or a device that is attached to the machine.

[0002]

[Prior Art]

 For example, as shown in FIG. 4, when the workpiece attaching / detaching robot 102 is provided on the front floor of the machine 101 (lathe), the power source for the robot 102 is usually supplied from the machine side. Conventionally, the method of supporting the electric wire and the hose of the power source is such that the electric wire and the hose 105 are attached to the upper end of the revolving body 103 of the robot and the power supply terminal box of the lathe by the belt-shaped spring steel 104, which is fixed at both ends, Many of them have a structure in which the electric wire and the hose are held by utilizing the bending and rectilinear movement of the strip spring steel that follows the turning movement of the body 103.

[0003]

[Problems to be solved by the device]

 The method of holding the wire and hose with the strip-shaped spring steel described in the prior art interferes with this machine when it is a long distance and hangs down by its own weight, or the spring steel itself bends in an unexpected direction due to aging. There was a problem that the wires and hoses were easily worn out and damaged. The present invention has been made in view of the above problems of the conventional technology, and an object of the present invention is to reduce the damage to electric wires and hoses even when used in a revolving structure having a high revolving frequency and to shorten the service life. It is long and replacement is intended to provide a support structure for wiring and piping that can extend the maintenance inspection period.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the wiring and piping structure for the revolving structure in the present invention is an electric wire and / or a pipe installed between this machine and a revolving structure which can be swung in a horizontal plane of a machine or a device attached to the machine. In the support structure of the fluid hose, a guide is provided on the machine along the electric wire and / or the hose, and a movable base movable along the guide and constantly urged by a spring to the side opposite to the revolving body is provided. A chain-shaped cable holding member is provided which is fixed to the revolving structure at both ends thereof and is fixed to the movable base and is movable in only one direction through which the electric wire or the hose is inserted and held.

[0005]

[Action]

 When the revolving structure of the side-by-side machine or device revolves, the tip of the chain-shaped cable holding member, whose tip is fixed to the mounting base fixed to the upper end of the revolving structure, is bent / returned along the specified bending radius. A support base having an L-shaped cross section to which the rear end of the chain-shaped cable holding member is fixed is moved along the guide base 8 by supporting the central portion and the rear end portion of the chain-shaped cable holding member. .. In this way, the chain-shaped cable holding member is operated smoothly without applying excessive force to reduce damage to the wires and / or hoses.

[0006]

【Example】

 Examples will be described with reference to FIGS. 1 to 3. In FIG. 1, a work attachment / detachment robot 2 is installed on the front floor of a lathe 1. In the robot 2, a revolving unit 4 is erected on a fixed base 3 so that the revolving unit 4 can swivel 180 ° in a horizontal plane, and an arm 5 is mounted on the revolving unit 4 so that the arm 5 can move horizontally and vertically. The robot hand 6 is provided at the tip of the robot so that it can be opened and closed, and the tip can swivel 180 ° from the wrist. A support base 7 is vertically attached to the upper end of the swivel base 4 at a position deviated from the swivel center by a substantially minimum bending radius of a frame-shaped chain 12 to be described later.

On the other hand, on the rear side of the lathe 1 is provided a terminal box (not shown) for supplying electric and fluid to the robot 2 side. A plurality of guide rollers 9 are rotatably provided on the guide base 8. A movable base 11 having an L-shaped cross section is supported by the guide roller 9 so as to be movable in the front-rear direction, and the movable base 11 is constantly urged toward the anti-robot side by a tension spring 15. Both ends of a chain-shaped cable holder 2 which is rotatable only in one direction in a horizontal plane are fixed to the movable table 11 and the support table 7, and a supply terminal box on the lathe side and a receiving terminal box 13 on the robot side. An electric wire and a hose 14 that are erected between and are held by being inserted through the chain-shaped cable holder 12. The chain-shaped cable holder 12 may be a commercially available one such as Runner Flex (upper and lower open / close type) manufactured by Captain Industry Co., Ltd. This allows a plurality of frames to rotate relative to each other. It is connected so that it can be bent in only one direction with a minimum specified bending radius.

Next, the operation of this embodiment will be described. When the revolving unit 4 pivots 180 ° so that the robot hand 6 of the robot 2 faces the work conveyor side (not shown), the chain-shaped cable holder 12 whose tip is fixed to the mount 7 as shown by the phantom line in FIG. The tip end of the robot bends along the minimum bending radius and moves the movable table 11 to the robot side against the force of the spring 15. As a result, the chain-shaped cable holder 12 is supported on the bottom plate of the movable table 11 and moved in the horizontal direction, so that the electric wire and the hose 14 are smoothly moved so as not to be damaged. Next, when the revolving unit 4 is turned 180 ° in the opposite direction so that the robot hand 6 faces the lathe 1, the moving base 11 moves to the anti-robot side by the force of the spring 15, as shown by the solid line in FIG. Then, the chain-shaped cable holder 12 becomes almost straight and moves smoothly so that the electric wire and the hose 14 are not damaged.

[0009]

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. Guide the rear end of the chain-shaped cable holding member, which is supported by inserting the electric wire and / or hose that is installed between this machine and the revolving structure of the machine or equipment attached to this machine, to this machine. The chain-shaped cable holding member is fixed to a moving table having an L-shaped cross section that is movable along the axis and is always biased to the side opposite to the revolving body by a spring. As it bends, the center and rear ends are supported by the support stand so that the chain-shaped cable holding member can move horizontally smoothly, so that the chain-shaped cable holding member hangs down by its own weight and an excessive load is applied. Since there is no edge, there is little damage to the inserted wire or hose. Therefore, the life of the electric wire or hose is extended and the replacement time is extended, and the time required for replacement or maintenance inspection can be greatly reduced.
