Abstract

PROBLEM TO BE SOLVED: To shorten the setup time and completely eliminate dispersion in binding diameter by installing a large bevel gear in the center of rotation of a freely rotatable bundling plate, transmitting the rotation of the large bevel gear to a small bevel gar and a ball screw, and providing a bundling guide moved right and lift, interlocking with the rotation of the ball screw. SOLUTION: A linear bearing 6 is smoothly moved on a slide rail 4, and a bundling guide 3 is fixed to the linear bearing 6. The bundling guide 3 is provided with a screw part 7, and the screw part 7 is threaded to agree with the pitch of a ball screw 5. Accordingly, the bundling guide 3 is capable of moving right and left, interlocking with the rotation of the ball screw 5. A small bevel gear 2 is fitted to the tip of the ball screw 5, and forced to interlock with a large bevel gear 1. When the large bevel gear 1 is rotated, the rotation is transmitted to the small bevel gear 2, and further transmitted to the ball screw 5. The bundling guide 3 is moved interlocking with the rotation of the ball screw 5, and the position of the bundling guide 3 can be adjusted by the rotation of the large bevel gear 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable binding device for a cable, particularly a cable having a relatively small diameter.

[0002]

2. Description of the Related Art FIG. 4 is a front view showing a conventional cable bundling machine. The bundler includes a bundle plate 23, a bundle fixing bolt 21, a bundle guide 22, and a slide guide 25. The bundling plate 23 has a structure that can be rotated clockwise and clockwise by a motor or the like. The slide guides 25 are provided at four locations by cutting the bundle take-up plate 23 radially and opposed to the rotation center.
The bundling guide 22 moves along the slide guide 25 to determine the bundling diameter of the cable. The adjustable bundle diameter is determined by the length of the slide guide 25 provided on the bundle plate 23.

FIG. 5 is an enlarged sectional view of a portion of the slide guide 25. FIG. 4 is a side view of a plane including the bundle fixing bolt 21 in FIG. To determine the bundle diameter, loosen the bundle fixing bolt 21 and move the bundle guide 22 to the slide guide 2 so as to have a desired diameter.
5 (in the direction perpendicular to the paper surface in FIG. 5), and then the bundle fixing bolt 21 is tightened to fix the bundle guide 22. Such an operation must be performed for the four bundle guides 22. At that time, it is necessary to pay sufficient attention to the setting of the bundle guide 22 so that the bundle diameter becomes the same. The bundle diameter generally varies depending on the size of the cable and the like.

After that, the distal end of the small-diameter cable is wound around four bundle guides 22, and the bundle plate 23 is rotated by a motor or the like.
Starts winding the cable by applying rotational force to the cable.

[0005]

The conventional cable bundling machine has the following problems.

[0006] All operations for determining a different bundle diameter depending on the cable size are manual operations. That is, the bundle guide 2
In order to set 2 at a desired position, the bundle fixing bolt 21 is once loosened, the bundle diameter is adjusted, and then the bundle fixing bolt 21 is adjusted.
Need to be tightened. This is performed for four bundle guides. This operation is called a setup operation. However, the conventional cable bundling machine has problems such as a long setup operation time and a variation in setting of a bundle diameter.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide a cable bundling machine in which the setup work time is short and there is no variation in the bundling diameter.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a large bevel gear provided at the center of rotation of a rotatable bundle plate, and a small bevel gear for transmitting the rotation of the large bevel gear. , A ball screw, and a bundle guide that moves left and right in conjunction with the rotation of the ball screw.

The four small bevel gears and the ball screws are provided radially and opposed to each other from the center of rotation of the bundling plate.

The large bevel gear is configured to be rotatable by a motor.

[0011]

FIG. 1 is a perspective view of a main part of an embodiment of a cable bundling machine according to the present invention. The portion referred to as the main part is a large bevel gear 1 provided at the center of rotation of the circular bundle plate.
, The bevel gear 2 and the bundle guide driving unit 8. The bundle guide driving unit 8 includes a ball screw 5, a bundle guide 3,
Slide rail 4, linear bearing 6, screw part 7
It is composed of

The linear bearing 6 can move smoothly on the slide rail 4, and the bundle guide 3 is fixed to the linear bearing 6. The bundling guide 3 is provided with a thread portion 7, which is threaded according to the pitch of the ball screw 5. Therefore, the bundle guide 3 can move left and right in conjunction with the rotation of the ball screw 5. The small bevel gear 2 is attached to the tip of the ball screw 5, and is configured to interlock with the large bevel gear 1.

When the large bevel gear 1 rotates, the rotation is transmitted to the small bevel gear 2 and further transmitted to the ball screw 5.
As described above, since the bundle guide 3 moves in conjunction with the rotation of the ball screw 5, the position of the bundle guide 3 can be adjusted by rotating the bevel gear 1 after all.

FIG. 2 is a schematic sectional view of FIG. As described above, the bevel gear 1 is provided at the center of rotation of the circular bundle plate 12, and the rotation is transmitted to the bevel gear 1 by the timing pulley 10, the timing belt 11, and the motor 9.

FIG. 3 is a front view of one embodiment of the cable bundling machine of the present invention. The small bevel gear 2 and the bundle guide driving unit 8 described above constitute one set, for a total of four sets, and the bundle plate 12
It is provided in. When the large bevel gear 1 installed at the center of the stacking plate 12 rotates, the rotation is performed by four small bevel gears 2.
And the four bundle guides 3 are simultaneously set at the same position from the rotation center of the bundle plate 12. This setting is performed by a motor. As a result, the setup time is reduced to 1/4 of the conventional manual operation, the setting of the bundle diameter is not varied, and the working efficiency is greatly improved.

[0016]

The cable bundling machine of the present invention uses a large bevel gear, a small bevel gear, a ball screw, a linear bearing, a slide rail, and a motor to set a bundling guide. The time, that is, the so-called setup time, can be greatly reduced, and an excellent effect that there is no variation in the bundle diameter is exhibited.
