Abstract

PURPOSE:To obtain a flat square wire having good winding shape and to improve the yield by providing a pressurizing device having a pressurizing roller by which the flat square wire is pressurized on the root side of a take-up furnace in a take-up device having a horizontal take-up furnace. CONSTITUTION:A round wire fed out from a feeding swift is rolled by a tusks head roll into a flat square wire W1 and taken-up by the horizontal take-up furnace 5 provided on the take-up device. By abutting the roller of a pressurizing device on a part of flat square wire W1 where the wire W1 is nearly floated from the surface of furnace in the vicinity of aligning winding terminal of wire W, the flat square wire is pressurized by dead weights of a roller 10, a shaft 11, a supporter 12 and a slide rod 13. An arm 16 is horizontally adjusted so that the vicinity of terminal part of aligning winding part on the flat square wire is pressurized by the roller 10. The pressurizing force is adjusted by increasing or decreasing dead weights of roller, etc., or spring constant of a spring 15. Thus, generation of whisker caused by jumping-out of the flat square wire is eliminated and the flat square wire having good winding shape is obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is formed into various springs,
TECHNICAL FIELD The present invention relates to a method and an apparatus for winding a rectangular wire used for automobile parts and the like.

[0002]

2. Description of the Related Art A conventional rectangular wire winding structure has a collar portion 7 at one end as shown in FIG. The flat wire W ₁ was wound around the surface. Then, the rectangular wire W ₁ started to be wound from the root of the collar portion 7 of the horizontal take-up hook 5 was successively slid toward the small diameter side and taken up by using the taper of the horizontal take-up hook. The rubber band 8 was wound around the end of the winding start portion as a stopper.

In the above structure, several turns are aligned winding from the root of the collar portion 7. Then, as it goes to the right side, that is, toward the smaller diameter side of the horizontal winding hook, a gap is formed between the rectangular wire and the hook surface.
In addition, since the progress of the rubber band 8 can be suppressed, the aligned winding collapses from a certain point on the shuttle surface, and the rectangular wires overlap each other to form a layer.

[0004]

However, in the above-mentioned conventional structure, there is a problem that the winding shape of the rectangular wire W ₁ is deteriorated due to the degree of tightening of the rubber band 8. For example, if the rubber band 8 is tightened too much, the rectangular wire W ₁ is less likely to be pushed out, and the phenomenon in which the vicinity of the end portion of the aligned winding, that is, the portion A in FIG. In this state, if winding further proceeds, A
Jump as if the rectangular wire of the part was suddenly crushed from the left and right,
One or a few rectangular wires have partially popped out of the surface of the hook (we call this state beard), and the winding shape partially deteriorates, resulting in entanglement and disconnection in the post process. Will cause.

In order to prevent the above rectangular wire from popping out,
When the above-mentioned raised portion was generated, it was necessary for the worker to manually smash the raised portion by crushing it. Therefore, it was necessary for a worker to monitor one piece of equipment thoroughly, which was extremely disadvantageous in terms of work efficiency.

If the rubber band 8 is tightened too weakly, the rectangular wire W ₁ easily slips on the taper surface of the horizontal take-up hook, and the overlapping of the rectangular wire with each other is reduced, so that the rectangular wire W ₁ can be taken up by the horizontal take-up hook. There is a problem that the amount of flat wire decreases and the finished product becomes a small bundle.

The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to prevent the rectangular wire from popping out, maintain a good winding shape without a beard, and do not require operator's monitoring. An object of the present invention is to provide a method of winding a wire and an apparatus thereof.

[0008]

In order to achieve the above object, a method for winding a rectangular wire, which is the first invention of the present invention, comprises:
When the rectangular wire is wound by the horizontal take-up hook, the vicinity of the end of the aligned winding part of the rectangular wire wound on the horizontal take-up hook is wound while being pressed toward the center of the hook by the pressing means. The flat wire winding device according to the second invention is
A winding device having a horizontal take-up hook is characterized in that a pressing device having a roller for pressing a rectangular wire is provided at the base side of the horizontal take-up hook.

[0009]

The floating portion generated in the vicinity of the terminal end of the aligned winding portion is broken into small pieces by the pressing means, so that the rectangular wire does not largely float from the horizontal winding hook. Since the rising part of the rectangular wire is generated partially rather than the entire circumference of the horizontal take-up hook, when the lifting part is pressed, the elastic part of the rectangular wire disperses the rising part in the circumferential direction, resulting in a large lifting part. Disappears. Therefore, it is possible to prevent the rectangular wire from popping out, and it is possible to maintain a good winding shape without a beard.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an overall front view of a rectangular wire winding device which is an embodiment of the present invention. The round wire W ₀ fed from the feeding Swift 1 is a rectangular wire W ₀ by the turks head roll 2.
_After being rolled to _1, it is wound up on a horizontal winding pot 5 provided in the winding device 3.

FIG. 2 shows a schematic cross section of the winding device 3 shown in FIG. 1 as viewed from the left side. The horizontal take-up hook 5 is rotatably attached to the machine base 4 via a shaft 6. The root has a collar 7 and is tapered toward the other end.

A pressing device 9 is provided on the upper part of the horizontal take-up hook 5 on the base side. The disc-shaped roller 10 is rotatably supported by a shaft 11. The shaft 11 is connected to a slide rod 13 via a support tool 12. The slide rod 13 is slidably fitted vertically on the inner circumference of the cylinder 14, and the uppermost portion is processed into a disc having a diameter larger than that of the rod. Tube 14
A spring 15 is arranged between the upper surface of the spring and the disk at the top of the slide rod, and the slide rod 13 penetrates the hollow of the spring 15. The cylinder 14 is fixed to the machine base 4 by an arm 16.

When the flat wire is actually wound up, the roller 10 of the pressing device is brought into contact with a portion of the flat wire which is near the terminal end of the aligned winding portion and the flat wire is rising from the hook surface. The flat wire is pressed by the weights of the roller 10, the shaft 11, the support 12, and the slide rod 13.

Further, the arm 16 can be moved left and right so that the roller 10 can press the vicinity of the end of the aligned winding part on the rectangular wire W ₁ wound on the horizontal winding hook 5. There is. The pressing force on the rectangular wire can be adjusted by increasing or decreasing the weight of the roller or the like or by increasing or decreasing the spring constant of the spring 15.

When a total of 500 kg of 1 mm square rectangular wires were actually wound by the above winding device, there was no protrusion of the rectangular wires, no beard occurred, and a good winding shape was obtained. Also, there were no tangles or disconnections in the subsequent process.

[0016]

As described above, according to the winding method and apparatus of the present invention, it is possible to obtain a flat wire having a good winding shape without the occurrence of beards due to the projection of the flat wire, which has been a problem in the prior art. . Therefore, entanglement and disconnection in the subsequent process are eliminated, and the product yield can be improved.

Further, since it is not necessary for the worker to monitor the winding device steadily, it is possible to greatly increase the work efficiency such that the number of holdings can be increased and other work can be performed.
