Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel for a wire bundle used for drawing a wire from a wire bundle such as a cable or a steel stranded wire used for power distribution work.

[0002]

2. Description of the Related Art Conventionally, wire bodies such as cables and steel strands used for power distribution work are generally handled by a drum winding using a wooden drum. Due to the trend of protection of wood resources and reduction of industrial waste, the use of linear bodies with coreless winding bundles without using drums has recently increased.

[0003] When a linear body is handled by a winding bundle, the winding is generally set on a reel for winding and the linear body is pulled out, but there is a problem with this. That is, in the case of a wound bundle, the linear body is not wound tightly as in the case of a drum winding, so that the wound bundle can be easily separated when pulled out from the reel. In addition, there is a problem that the end of the linear body may be repelled by the "separation" and a danger may be given to an operator.

In order to cope with such a problem of "separation", conventionally, an appropriate brake is applied to the reel by appropriately devising for each site, or a reel with a brake is used. As a problem, it is not always possible to effectively prevent the "separation" by using only the brakes, and the brakes cause great resistance to pulling out the linear body.
This imposes an extra burden on the worker.

Under the circumstances described above, the applicant of the present invention has previously filed Japanese Patent Application No. 6-202042 (Japanese Patent Application Laid-Open No. 8-59093).
Nos., Hereinafter referred to as prior art 1) and Japanese Patent Application No. 7-131649 (hereinafter referred to as prior art 2), each proposed a novel reel for winding a linear body. The linear body winding bundle reel of the prior art 1 is a type that is used by being rotatably supported on a gantry, and is provided with idler wheels that regulate the outer periphery of the winding bundle while rotating freely. Regulations have eliminated the problem of "loose" windings. On the other hand, the reel for a linear body winding bundle according to the prior art 2 has a plurality of rollers that respectively support the outer periphery, the side surface, and the inner periphery of the winding bundle attached thereto, and the winding bundle itself is supported by these rollers. The structure is such that the linear body is pulled out while being rotated, and the problem of "scattering" of the winding bundle is solved by regulating the outer periphery of the winding bundle with rollers.

These reels for winding a linear body each have excellent characteristics. However, on the other hand, the linear body winding bundle reel of prior art 1 has a drawback that the structure is complicated, and the linear body winding reel of prior art 2 has a side support roller. Since it is required on the left and right, there is a drawback that the width is large and the size is large, and therefore, the in-vehicle mountability when mounted on a truck is poor.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances. The present invention aims at simplifying the structure of a reel for winding a linear body which can prevent the "separation" of the bundle. The purpose is to reduce the size, particularly to reduce the spread of the width.

[0008]

A reel for winding a linear body according to the present invention includes a frame body and a rotating body rotatably supported by the frame body, wherein the frame body includes a plurality of annular members. Are connected to each other by a plurality of horizontal rails, formed in a short cylindrical shape and attached with a plurality of rollers, an outer peripheral regulating frame, a rotation supporting shaft disposed at the center of the outer peripheral regulating frame, and the outer peripheral regulating frame and the rotating supporting shaft. The rotating body has a plurality of connecting arms for connection, the rotating body has an annular outer peripheral rim formed to have a smaller diameter than the outer peripheral regulating frame, a barrel rotatably supported by the rotation support shaft, and these outer peripheral rims. A body unit having a plurality of connection arms for connecting the barrel, an outer rim paired with the outer rim of the body unit, a mounting portion for mounting to the barrel, and an outer rim and a mounting portion. A plurality of connecting arms connected to each other, comprising a detachable unit detachably attached to the main body unit through the attaching portion, and removing the detachable unit and opening one side to form a line to the rotating body. The winding bundle attached to the rotating body can be mounted, and the outer circumference of the winding bundle is regulated by the rollers of the outer periphery regulating frame. In this state, the winding bundle is rotated together with the rotating body to draw out the linear body. It is made to be.

In order to use this reel for winding a linear body,
First, the detachable unit is removed to open one side of the rotating body. In this state, if the winding bundle is mounted on the rotating body and the detachable unit is mounted, the linear body can be pulled out. When the linear body is pulled out in this state, the winding bundle rotates together with the rotating body, so that the linear body can be smoothly drawn continuously. Further, the wound bundle is regulated while the outer periphery thereof is in sliding contact with the rollers of the outer periphery regulating frame and these are rotated. As a result, it is possible to effectively prevent "split" of the wound bundle without giving a large resistance to drawing out the linear body.

[0010] Such a reel for winding a linear body according to the present invention is similar to the reel for winding a linear body according to the prior art 2 in that the outer circumference of the winding is regulated by a roller provided on an outer circumference regulating frame. Therefore, the structure is simplified as compared with the reel for winding a linear body according to Prior Art 1 described above. Further, in comparison with the linear body winding reel of the prior art 2, the side of the winding bundle as in the linear body winding reel of the prior art 2 was made by rotating the winding together with the rotating body. The need for supporting rollers can be eliminated, and the width can be reduced accordingly. That is, the width can be reduced. For example, in the case of a bundle having a width of about 200 mm, the width can be reduced by about 120 mm.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.
The reel for winding a linear body according to the present embodiment is shown in FIGS.
As shown in FIG. 1, the frame body 1 includes a rotating body 2 supported by the frame body 1 and a terminal stopper 3.

The frame body 1 has a structure in which a rotation support shaft 5 disposed at the center and an outer peripheral regulation frame 6 disposed on the outer periphery are connected by six connection arms 7, and the rotation support shaft 5 of the connection arm 7 is connected to the rotation support shaft 5. Is fixed via a flange 8 provided on the rotation support shaft 5. The outer peripheral regulating frame 6 is formed into a short cylindrical shape by connecting two annular members 10 each using a pipe with a horizontal rail 11 integrated with each of the connection arms 7, and is formed at a position of each horizontal rail 11. Roller 1 parallel to horizontal rail 11
Attach 2.

The rotator 2 is formed by a main unit 13 and a detachable unit 14 which is detachable therefrom. The main unit 13 has a structure in which a barrel 15 arranged at the center and an outer rim 16 arranged at the outer periphery are connected by four connection arms 17. The body tube 15 is formed in a cylindrical shape having a thickness that can be fitted to the rotation support shaft 5 with a ball bearing 18 interposed therebetween, and a mounting receiving portion 20 is provided at a distal end thereof. The mounting receiving portion 20 is formed by holding a U-shaped bracket 22 with holding bolts 21 passed from the outside to the inside of the barrel 15, and holding the screw receiving bolts 23 on the bracket 22. On the other hand, the outer peripheral rim 16 is formed to have a diameter such that the outer peripheral rim 16 is in contact with or slightly apart from the roller 12 inside the outer peripheral regulating frame 6. The main unit 13 is fitted on the rotation support shaft 5 via the barrel 15, and a ball bearing 18 is interposed between the barrel 15 and the rotation support shaft 5.

The detachable unit 14 has a structure in which an outer peripheral rim 25 similar to the outer peripheral rim 16 is connected to a center mounting portion 24 by four connection arms 26. The mounting portion 24 rotatably holds a screwing pin 28 having a female screw which can be screwed with the screwing receiving bolt 23 on the basis of the flange 27 so as to be rotatable. 29 is protruded. The mounting of the main unit 13 to the mounting receiving portion 20 by the mounting portion 24 is performed by screwing the screwing pin 28 to the screwing receiving bolt 23.
At this time, the engagement concave portion 30 at the tip of the engagement cylinder 29 is engaged with the holding bolt 21 (FIG. 4), so that the connection arm 17 of the main body unit 13 and the connection arm 26 of the detachable unit 14 correspond to each other. be able to.

The terminal stopper 3 is for fixing the end of a linear body in a bundle to be mounted as described later, and has an outer diameter and an inner diameter slightly smaller than the inner diameter of a general bundle. And assembled so that it can freely rotate around the rotation support shaft 5. Since the terminal stopper 3 is annular, the terminal of the linear body can be fixed at an arbitrary position on the entire circumference, and restrictions on the terminal fixing position can be eliminated. In addition, since it can be freely rotated around the rotation support shaft 5, it also functions to eliminate the "burr" of the linear body in a state where the remaining bundle is reduced. That is, a certain kind of stress is applied to the terminal when the linear body is pulled out, and when this stress accumulates, when the remaining of the winding bundle is reduced, there is a risk that the linear body will "blur". By freely rotating around 4, the above-mentioned stress can be absorbed and the cause of "squashing" can be eliminated.

The state of use of such a reel for winding a linear body is as follows. First, a winding bundle of a linear body is mounted. This work is normally performed with the frame body 1 side down on the ground, and the detachable unit 14 is first removed from the main unit 13. Next, the main unit 13
Is attached with the bundle M. Then, the terminal of the linear body W is taken out from the winding bundle M, fixed to the terminal stopper 3 by tying it to the terminal stopper 3, and the detachable unit 14 is attached to the main unit 13 again. In this state, the linear body W can be pulled out. Usually, the linear body W is pulled out by applying a suitable stopper B or the like in a state where the linear body W is raised and made vertical, but it is also possible to perform the drawing while keeping the horizontal state.

When the linear body W is pulled out, the winding bundle M rotates together with the rotating body 2, whereby the linear body W can be drawn out smoothly. The outer circumference of the wound bundle M is slidably brought into contact with the rollers 12 of the outer-periphery regulating frame 6 and is regulated while rotating them. As a result, the winding M can be “separated” without giving a large resistance to pulling out the linear body W.
Can be effectively prevented.

[0018]

As described above, the reel for winding a linear body according to the present invention enables the linear body to be smoothly pulled out with a small pull-out resistance while effectively preventing the "winding" of the wound bundle. In addition to the effect that can be achieved, along with the simplification of the structure, miniaturization, especially in terms of width,
There is an effect that the usability can be improved, such as being excellent in vehicle mountability.
