[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically fixing a cable winding start end to a cable drum, and more particularly to an improvement in a structure for attaching the cable winding end to a cable drum flange.

[0002]

2. Description of the Related Art As shown in FIG. 10, a cable extruder (not shown) from a jacket extruder (not shown) guides a cable a to a take-up machine 21. It is wound around a winder 23 via a traverser 22. A plurality of winding machines 23 are installed, and when each cable drum 1 is fully wound, an operator cuts the cable a at the exit of the winding machine 21 and connects the end a ′ to the empty cable drum 1. As shown in FIG. 11, the cable a is continuously guided by being guided from the outlet 2 of the cable drum flange 1a to the outer fixing device A, switching the winding drum, and rotating the cable drum 1. It is wound up.

As described above, since the cable a is continuously wound, it is necessary to smoothly fix the cable winding start end a 'to the cable drum 1. For this reason, the applicant of the present application has proposed an automatic fixing device for a cable winding start end disclosed in Japanese Utility Model Laid-Open No. 3-125765.

[0004] This automatic fixing device comprises a cable drum flange 1
When a tubular body is provided on the side surface of a and a cable winding start end a 'is inserted into the tubular body, the insertion causes the claws to bite into the cable terminal and chuck.

[0005]

When the above-mentioned automatic fixing device is attached to the cable drum 1, the cylindrical body is pulled out in the direction in which the cable winding start end a 'led out from the outlet 2 on the side of the cable drum flange 1a. It is necessary that the direction of the cylinder axis is oriented, otherwise, the cable winding start end a 'cannot be smoothly inserted into the cylinder.

However, in the conventional automatic fixing device described in the above-mentioned publication, the inclination (direction) of the cylindrical body cannot be adjusted in the state of being fixed to the flange 1a. That is,
Usually, the fixing device is fixed to the rib (flange) of the trunk, but the amount of protrusion of the rib is small, and it is difficult to fix the cylindrical body in any direction (see the above-mentioned publication and the examples).

If the size (diameter) of the cable drum is different, the leading direction of the cable winding start end a 'is also different. Therefore, it is necessary to adjust the cylinder in the leading direction for each drum having a different size. It is very difficult to cope with such a problem due to the small protrusion amount of the rib and the difference in the curvature of the rib.

For this reason, when the conventional automatic fixing device is mounted, the leading direction of the winding end of the cable does not match the direction of the cylindrical body, and the end cannot be smoothly inserted into the cylindrical body in some cases. .

[0009] This invention, even after mounting on the collar,
If the direction of the cylinder can be adjusted, paying attention to the fact that the cylinder can correspond to the outlet without being affected by the small amount of protrusion and the difference in the rib curvature, the orientation of the cylinder is adjusted. The task is to be able to do so.

[0010]

In order to solve the above-mentioned problems, according to the present invention, when a cable winding start end is inserted into the above-mentioned tubular body, the insertion causes the claws to bite into the cable terminal to chuck. In the cable winding start end fixing device described in the above-mentioned publication, a connection support metal is provided on the fixing metal fixed to the flange of the cable drum body so as to be vertically swingable and fixable. ,
The support bracket fixed to the cylindrical body is provided so as to be swingable and fixable in the front-rear direction.

[0011]

In the cable winding start end fixing device according to the present invention, the connecting support fitting is swung up and down relative to the fixing fitting after the cable drum is temporarily fixed to the flange, and the supporting fitting is connected to the connecting support fitting. To adjust the cylindrical body in the direction in which the cable winding start end is led out, and then fix each bracket.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 to 9, a winding start end outlet 2 is formed on a side surface of a cable drum flange 1a so that a cable winding end a 'is drawn out from the inside to the outside. A tubular body 3 is provided in the direction in which the cable winding start flange a ′ is led out from the cable body 2, and a cutout hole 4 is formed in the tubular body 3 in the circumferential direction. The arm 5 is attached to the cylinder 3 so as to be swingable in the direction in which the arm 5 moves. The claw arm 5 and the cylindrical body 3 (the hook 4
An extended coil spring 10 is provided between 8), so that the claw arm 5 always enters the cylindrical body 3.

In the cylinder 3, a piston plate 7 has a shaft 7a.
Is inserted through the bearing 6 so as to be movable in the cylinder axis direction.
The locking rod 9 is led out via the.

When the locking rod 9 comes out of the elongated hole 8, the vertical rod 9b
And the horizontal rod 9c, and the two rods 9b and 9c are rotatably connected. In the vicinity of the notch hole 4 of the cylindrical body 3, a support piece 16 is provided.
An end piece 9a of the horizontal rod 9c is rotatably connected to the engagement piece 14 via a pivot. The vertical rod 9b is connected to the elongated hole 8 as shown in FIG. 5 is in contact with one end (notch hole 4 side) of the locking piece 14 as shown in FIG.
Are locked to the claw arm 5 to prevent the claw arm 5 from entering the notch hole 4.

From this state, the cable winding start end a 'is guided from the outlet 2 into the cylindrical body 3 as shown by the arrow in FIG. 2, and as shown in the chain line in FIG. 5 and FIGS. When the piston plate 7 is pressed, the locking rod 9 moves as the piston plate 7 moves.
And the locking piece 14 swings and disengages from the claw arm 5, the claw arm 5 swings through the notch hole 4 into the cylindrical body 3 by the spring 10, and the claw 5 a of the cable winding start end a I'm going to bite and chuck.

An extended coil spring 15 is provided between the vertical rod 9b of the locking rod 9 and the cylindrical body 3, and swings the pawl arm 5 outward (open) from the chucking state. hand)
When the bite of the claw 5a is released and the cable winding start flange a 'is pulled out from the cylinder 3, the locking rod 9 is pulled toward the claw arm 5 by the spring 15, and the locking piece 14 swings as shown in FIG. It moves and locks inside the claw arm 5, and enters an initial standby state.

On the other hand, as shown in FIGS. 1 to 3, the cylinder 3 is fixed to the flange (rib) 1b of the cable drum body and the cylinder 3 is fixed to the cable drum 1. Support bracket 35, and both brackets 30, 35

The connecting bracket 40 has a substantially U-shaped piece 40.
a is a shape in which a triangular piece 40b is erected at the end of a, and two long holes 41a, 41b
And 42a, 42b, and round holes 43, 44 in the center thereof. Each of the holes 41a is provided with a fixing bolt 45 passing through the fixing bracket 30 and the supporting bracket 35.
5 by screwing the nut 46 to the connection support fitting 40.
The fixing fitting 30 and the supporting fitting 35 are tightened and fixed to the fixing member 30.

Before the tightening, the bolts 45 of the round holes 43 and 44 are used as shafts within the moving range of the bolts 45 in the elongated holes 41a.
, And the support bracket 35 swings back and forth with respect to the connection support bracket 40. This swinging causes the cylindrical body 3 to swing up and down and back and forth.

This embodiment has the above configuration.
The procedure of fixing the cable winding start end according to this embodiment will be described. Before switching the winding cable drum 1, as shown in FIG. The U-shaped pieces 31, 31 are fitted to the flange 1b of the body,
Fix with bolts 32.

At this time, when the cylinder 3 does not coincide with the direction in which the cable winding start end a 'is led out from the outlet 2, the nut 46 is loosened and the cylinder 3 is swung up and down and back and forth. Let match. If they match, tighten the nut 46,
The metal members 30, 40, and 35 are integrated, and the cylindrical body 3 is fixed. Thereafter, by the above-described operation, the cable winding start end a 'is inserted into the cylindrical body 3 and chucked, and the chucking is removed and taken out.
