Abstract

PROBLEM TO BE SOLVED: To reduce an area required for winding even when a wire type material protecting apparatus is wound up and to reduce stress to the wire type material protecting apparatus and to the wire type material. SOLUTION: In a wire type material protecting apparatus 1 constructed by connecting multiple protection tools into a chain shape by means of pins and pin holes, a wire type material (a cable and the like) is stored in the inside. On one side in the pin hole, a hole diameter is increased, so that the pin can be oscillationally moved in the pin hole. Therefore, the wire type material protecting apparatus 1 can be wound spirally on the circumference face of a drum 12. Even when the wire type material protection apparatus 1 is long in length, a winding diameter is not changed though a winding height is increased, so that an area required for winding is small, while stress onto the wire type material can be reduced because of no fluctuation in the winding diameter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rod protector and a wire rod protector winding device, which extends the life of the wire rod protector and the wire rods (cables and hoses) and winds them up. It is designed so that the area is small.

[0002]

2. Description of the Related Art In machines equipped with a swivel unit such as robots and automatic machines, flexible materials such as cables for sending electric power and signals to the swivel unit and hoses for supplying air to the swivel unit are used. Included in a material protector to protect the linear material.

FIG. 5 shows a conventional wire material protector 01, which is called, for example, a cable bear (trade name). The linear member protector 01 is configured by connecting a large number of protective members 02 formed of a rigid member (metal such as iron). More specifically, each protection member 02 has a pin 03 at one end and a pin hole 04 at the other end. Then, between adjacent protection members 02, the pin 03 of one protection member 02 is pin hole 0 of the other protection member 02.
It is fitted in 4 and is connected like a chain. Therefore, by rotating between the pin 03 and the pin hole 04, the entire wire protection member 01 can be bent. For example, in FIG. 5, the wire protection device 01 is shown by a solid line. It is possible to bend from the state shown by the dotted line. in this way,
The constructed linear material protector 01 contains linear materials such as cables and hoses.

In order to store the above-mentioned linear material protector 01, as shown in FIG. 6, the linear material protector 01 is swung and wound (swirl winding type), or shown in FIG. like,
The wire protector 01 was wound around the drum 05 (a shaft winding type). Note that, in FIG. 7, the state in which the linear member protector 01 is wound is shown by a one-dot chain line, and the extended state is shown by a two-dot chain line.

[0005]

By the way, in the swivel winding type shown in FIG. 6, since the lower surface of the wire protector 01 slides on the floor every time it is wound and unwound, the wire protector 01 Wears out. In addition, the cables and hoses contained in the wire protection device 01 are subject to a large stress because the bending direction and radius change greatly, from right bending with a large radius to right bending with a small radius and left bending with a small radius. Join. For this reason,
The life of cables and hoses is shortened.

Further, in the shaft winding type shown in FIG. 7, the wire material protector 0 is wound every time the winding / unwinding process is performed, as in the swirling winding type.
Since the lower surface of 1 slides on the floor surface, wear of the wire protector 01 occurs. It should be noted that the bending radius changes little with respect to the stress applied to the cable and the hose, and the cable and the hose do not bend in the opposite direction, so the life of the cable and the hose is long. However, when the rotation angle of the turning becomes large, a very large area is required to wind up the linear material protector 01.

In view of the above-mentioned prior art, the present invention requires less wear on the wire protector and requires a smaller area for winding even if the turning angle is large, and the wire (cable, hose). It is an object of the present invention to provide a wire protector and a wire protector take-up device with a small change in bending radius.

[0008]

The structure of the present invention for solving the above-mentioned problems comprises a large number of protective members which have a pin at one end and a pin hole at the other end and enclose a linear material, and which are adjacent to each other. In the linear member protector in which the pins of one of the protection members are fitted into the pin holes of the other protection member and connected in a chain shape between the protection members, a pin on a predetermined end face side of the pin holes. A feature of the hole is that the pin has a clearance such that the pin can swing and move in the pin hole even if the pin is fitted.

Further, the present invention comprises a large number of protective members having a pin at one end and a pin hole at the other end and containing a linear material, and between adjacent protective members, a pin of one protective member is provided. Is inserted into the pin hole of the other protective member and is connected in a chain shape. Moreover, in the pin hole on the end face side that is determined in advance among the pin holes, even if the pin is inserted, this pin will be in the pin hole. It is characterized in that it is provided with a linear material protector provided with a gap that allows it to oscillate and move, and a drum for spirally winding the linear material protector.

It is formed of a rigid member such as iron, and has a pin 3 at one end and pin holes 4a and 4b at the other end.
One of the pin holes 4a and 4b has a diameter such that the pin 3 of the adjacent protection member 2 is rotatably and tightly fitted. On the other hand, the other pin hole 4b has a diameter larger than that of the pin hole 4a so that the play when the pin 3 is fitted into the pin hole 4b becomes large. That is, the pin hole 4b has a margin in the α direction in FIG. Therefore, the pin 3 fitted in the pin hole 4b can swing in the α direction in the pin hole 4b.

By connecting a large number of protective members 2 described above, that is, between adjacent protective members 2, the pin 3 of one protective member 2 and the pin hole 4 of the other protective member 2 are connected.

The wire protector 1 includes a pin 3 and a pin hole 4a,
By rotating with 4b, it is possible to bend in the state shown in FIG. 5 as in the conventional case. Furthermore, since the pin hole 4b formed on the other end surface of the wire protector 1 has a large diameter, the pin 3 in the pin hole 4b swings and moves,
As shown in FIG. 3, it is possible to bend in a direction orthogonal to the bending direction shown in FIG.

Returning to FIG. 1 and FIG. 2, the linear material protector 1 (having a structure as described with reference to FIGS. 3 and 4) is a linear material protector winding device. Built in 10. In this linear material protector winding device 10, a drum 12 is arranged in a housing 11. The drum 12 is mounted with its axis vertical.

In the above-described wire material protector winding device 10,
The wire protector 1 does not slip on the floor surface even when it is wound or unwound, and the wire protector 1 is not worn. Further, there is no change in the winding diameter of the wire protector 1 and the wire (cable or hose) contained therein. Further, even if the rotation angle of the turning is large, the linear material protector 1 is wound in a spiral shape, and thus extends in the height direction, but a large area is not required for winding.

[0018]

As described above in detail with reference to the embodiments, according to the present invention, the linear member protector does not slip even if the linear member protector is wound or unwound. The wear of the material protector can be reduced and the life can be extended.

Further, since the wire protector is wound in a spiral shape, the change in winding diameter is small, stress on the wire is reduced, and the life of the wire can be extended.

Further, since the wire protector is wound in a spiral shape, the winding area may be small even if the turning angle of turning is large.
