Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for stably supplying a metal wire body bundled into a coil onto a carrier to the next work process.

Conventional feeding devices have a structure that allows the carrier to be placed on a turntable coaxially and integrally rotating, and while it has the advantage of being able to process large bundles of metal wires, on the other hand, the feeding speed is slow. The disadvantage was that it was limited to relatively low speeds.

The reason for this is that if the speed at which the metal wire is drawn out from the carrier on the turntable is high, the coil diameter of the few turns on the pull-out side of the coil bundle will gradually decrease, and eventually the coiled metal wire will be drawn out from the carrier. is tightened, the metal filament goes into tension for the next process, and the next moment the turntable suddenly rotates at high speed, faster than the speed at which the metal filament is pulled out, similar to spinning a top. As a result, all the tension in the metal filament is released and the metal filament is loosened, the diameter of the coil on the drawer side expands excessively, and the turntable approaches a standstill.
Then, since the drawing speed is fast, the coil diameter starts to be reduced again, and the process is repeated thereafter. This is because several turns of the coiled metal wire on the drawer side of such a coil bundle sometimes get tangled and get caught when loosening and tightening, causing trouble.
The maximum feeding speed is approximately 50 m/min. For this reason, there were complaints that the conventional equipment could not provide high-speed supply and could not speed up the next process.

The present invention solves the above-mentioned problems all at once. A capstan is provided coaxially and integrally rotating on a rotating disk on which a carrier is mounted, and the diameter of the winding surface of the capstan is set by adjusting the diameter of the winding surface of the capstan into a coil bundle of metal. The metal wire body is formed to have the same diameter as the coil diameter of the wire body and the same surface width so that it can be wound several times, and the metal wire body pulled out from the carrier is guided to the capstan via a guide roll, and the metal wire body is guided to the capstan through the guide roll, and the metal wire body is formed to have the same surface width as the coil diameter of the wire body. By winding it several times and then pulling it out continuously, it eliminates the phenomenon of expansion and contraction of the coil diameter of the coiled metal wire bundle in the carrier, and enables stable supply of the metal wire through the capstan even at high speeds. It is.

The drawings show an example of implementation of the device of the present invention,
A capstan 2 and a rotary disc 3 are provided on the turntable 1 on the bed 6 so as to coaxially rotate together, and a pole 7 erected on the bed 6 beside these is equipped with a capstan 2 and a rotary disc 3 on the turntable 1. an upper guide roller 4 that horizontally pulls out the metal wire body a from a carrier 5 mounted on the carrier 5 and guides it downward; A guide roller 4a is provided, and a guide roll 8 is provided on the bed 6 beside the wrapping surface 2a to horizontally pull out and guide the metal wire body a from the wrapping surface 2a.

The capstan 2 has a winding surface 2a having the same diameter as the coil diameter of the coil bundle-shaped metal wire body a, and is formed so that the metal wire body a can be wound several times around the same surface width. A presser roller 9 set on the base 6 is in pressure contact with this wrapping surface 2a, and this presser roller 9 presses the metal filament a and presses the wrapping surface 2a.
a to prevent it from sliding in the circumferential direction.

The rotating disk 3 has an upper surface serving as a mounting surface 3a for the carrier 5, and has an engaging convex portion 3b protruding from the center thereof, so that the carrier 5 can be pivotally supported for integral rotation.

The brake drum 10 is provided on the lower surface of the capstan 2 coaxially and integrally rotating, and a coil spring 1 set on the bed 6 is mounted on the drum surface.
A brake ring 13, which is tensioned in the radial direction at 1 via the actuating rod 12, is provided in an encircling manner, making it possible to receive a rotational resistance proportional to the spring force of the coil spring 11. This coil spring force can be changed from no load to a desired load value by rotating an adjustment nut 14 screwed onto the operating rod 12, and the spring force slightly affects the rotation of the capstan 2, etc. The resistance is applied so that the metal filament a drawn out from the winding Figure 2a is fed without loosening between the winding process and the next process.

Each guide ring 15 has guide rollers 4 and 4, respectively.
A is provided close to the guide rollers 4, 4a to prevent the metal wire body a from coming off the guide rollers 4, 4a.

Next, to explain the supply state of the metal filament a, first, the carrier 5 is placed on the mounting surface 3a of the rotating disk 3.
Then, while rotating the integrally rotating carrier 5, rotary disk 3, capstan 2, and turntable 1 counterclockwise, the left-handed coil bundle metal wire body a loaded on the carrier 5 is rolled from its winding end. Guide ring 15, guide roll 4, guide ring 1
5. Pass the guide roll 4a and the guide ring 15, and turn it counterclockwise to the winding surface 2a of the capstan 2.
After winding ~7 times, it is pulled out from the winding surface 2a and sent through the guide roll 8 to the next process.

As a result, as the metal filament a is continuously pulled out from the winding surface 2a by the pulling force on the next process side, the capstan 2 rotates to the left as if turning a top, and the length to be pulled out is The metal wire a is continuously wound from the carrier 5 through the guide rolls 4 and 4a, and the carrier 5, which rotates counterclockwise together with the capstan 2, continues to roll the metal wire a for the length to be wound on the winding surface 2a. Since there is no excess or deficiency between the drawn-out length and the fed-out length, the coil bundle-shaped metal wire body a on the carrier 5 is continuously supplied to the next process via the capstan 2.

Therefore, the present invention has the following advantages.

The length of the metal wire body fed out from the carrier matches the length of the metal wire body drawn out through the capstan, so that the coil diameter of the coil bundled metal wire body does not decrease or expand in the carrier, and the bonding is prevented. There is no need to apply too loosely, and troubles such as tangling do not occur, allowing for stable supply to the next process.

The feeding speed remains stable even when the linear speed exceeds 100 m/min, making it possible to speed up work in the next process and significantly improve work efficiency.

The capstan and the rotary disk are coaxially arranged on the turntable, and it operates well, does not need to be bulky, and is easy to transport and install.
