Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire storage machine used to continuously operate a wire winding machine such as a high-speed single spooler.

Conventionally, in order to continuously wind wire with a high-speed single spooler, an accumulator has been used to store the wire when changing the winding bobbin. but,
When winding a wire at high speed, the wire speed is 500 m/min or more, so a large amount of wire is stored in the accumulator during replacement of the winding bobbin, and the number of sheaves in the accumulator increases. For this reason, the inertia of the accumulator increases and the follow-up speed of the accumulator becomes low.Therefore, there is a drawback that the accumulator cannot follow fluctuations in the tension of the wire during winding, and the wire tends to elongate or break.

An object of the present invention is to provide a wire storage machine that can quickly follow fluctuations in wire tension, has a large storage capacity, and can be used for high-speed winding.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a wire storage machine 10 according to the present invention,
This wire storage machine 10 includes a dancer roll means 12 and an accumulator means 14 through which the wire 1 to be stored passes.
It is equipped with The dancer roll means 12 consists of a fixed sheave 12A and a movable sheave 12B, and since these sheaves are used to absorb fluctuations in the tension of the wire rod during normal winding, as will be described later, the amount of accumulated wire is relatively small. There are about 4 pieces each. On the other hand, the accumulator means also has a fixed sheave 14.
A and a movable sheave 14B, but since these seams are used to store the wire while winding is stopped, the amount of stored wire is large, for example, 13
1 piece. The drive source for driving the dancer roll means 12 consists of a braked induction motor 16, which is connected via a powder clutch 18 to a driven drive wheel 20. The drive wheel 20 consists of a wire wheel that winds a wire 22 connected to the movable sheave 12B, and this wire wheel is connected to the movable sheave 12B by the wire 22 so as to raise the movable sheave 12B by winding the wire 22. has been done. Also,
The drive source for driving the accumulator means 14 consists of an induction motor 24, which drives the drive wheels 2 through a powder clutch 26.
8 is connected. The drive wheel 28 is the movable sheave 1
4B, the wire wheel winds the wire 30 connected to the wire 30.
The movable sheave 14B is connected to the movable sheave 14B by the wire 30 so that the movable sheave 14B is moved to the right by winding the wire 30 and the wire 1 is stored.

The wire storage machine 10 further includes a dancer roll locking means 32 for locking the movable sheave 12B of the dancer roll means 12 in a predetermined position and an accumulator means 1.
The accumulator lock means 34 locks the four movable sheaves 14B in a predetermined position. The dancer roll locking means 32, in the illustrated embodiment, consists of an induction motor with a brake, and the accumulator locking means 34 consists of a lock cylinder. These locking means 3
2 and 34 are movable sheave 12 whose accumulated radiation dose reaches a predetermined value.
It includes lock position detectors 33 and 35 for detecting the dancer roll lock position and the accumulator lock position for detecting the predetermined positions of the rollers B and 14B, respectively.

The control unit 36 receives a wire storage signal generated by stopping a wire winding machine (not shown) and position signals from the lock position detectors 33 and 35, and controls the dancer roll locking means 32 and the accumulator locking means 34. and operate in a predetermined manner. That is, the control unit 36 releases the dancer roll locking means 32 and operates the accumulator locking means 34 when the winding machine is performing normal winding and is not receiving the wire storage signal, and also operates the accumulator locking means 34. When the winding bobbin is being replaced and a wire storage signal is received, the dancer lock means 32 is operated and the accumulator lock means 34 is released. The operation of the dancer roll locking means 32 and the accumulator locking means 34 is controlled by the control unit 3.
6 no longer receives or receives a storage line signal from the lock position detectors 33, 35 and starts.

Next, the operation of the wire storage machine 10 will be described with reference to FIG. 2. When the winder is performing normal winding, the movable sheave 1 of the accumulator means 14
4B is locked by the locking means 34 at the position shown by the imaginary line in FIG. ing. Since the dancer roll means 12 has small conventional and mechanical losses, it has good followability and can control the tension of the wire rod 1 with high responsiveness. In this state, the induction motor 24, which is the drive source of the accumulator means 14, is being driven, but the powder crack 26 is in a state of weak tension, and when the accumulator lock means 34 is released, the storage wire is immediately removed. I'm waiting for you to be able to. When the winder reaches full volume, the winder stops at the fixed length, and the second
When the line storage signal is applied to the control unit 36 at point a in the figure, the powder clutch 18 for the dancer roll means 12 increases its powder current to medium tension and its movable sheave 12B moves towards the fixed sheave 12A. When the lock position is detected by the dancer roll lock position detector 33, the induction motor 16 is stopped and the powder clutch is brought to the highest tension state, causing the movable sheave 12
B is braked and locked. on the other hand,
When the storage signal enters the control unit 36, its locking means 34 is immediately released, but the powder clutch 26 is intensified with powder current for t seconds thereafter when the movable sheave 12B of the dancer roll means 12 is secured. Therefore, the response speed of the movable sheave 14B of the accumulator means 14 is increased for this t seconds, and the wire can be stored well.
In this way, when the winder is stopped, the wire is stored by moving the movable sheave 14B of the accumulator means 14 to the right. After the winding bobbin of the winder is replaced, the winder is operated again at point b in FIG. At this time, the winding speed of the winder is slightly higher than usual, for example, by about 20%, and the accumulator means 14
The wire rod 1 inside is pulled out and its movable sheave 14B is moved to the left side. On the other hand, since there is no wire storage signal at this time, the movable sheave 14B is locked by the lock position detector 35.
When this point is reached, the accumulator locking means 36 operates to lock the movable sheave 14B. Also,
At this time, the powder clutch 26 becomes under low tension.
On the other hand, the induction motor 16 is driven, the brake is disconnected, the powder clutch 18 changes from the maximum current to the normal tension current, and the dancer roll means 12
controls the tension of the wire 1. In addition, in Figure 2,
"ON" indicates an operating state, and "OFF" indicates an inactive state. The powder clutches 18 and 26 also show less slippage as they move upward in FIG.

According to the present invention, as described above, during normal winding, the tension is controlled by the dancer roll means, so the wire does not elongate or break, and during wire storage, the accumulator means works to ensure sufficient tension. The line speed can be increased from 500 m/min to the conventional 500 m/min.
Since the speed can be increased to 950 m/min, there is a practical benefit of improving work efficiency.
