Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for feeding a wire material for feeding a wire material from a winding bundle material in which the wire material is wound into a coil shape and sending the wire material to a wire material processing device or the like. .

[0002]

2. Description of the Related Art A method of feeding a wire material from a winding bundle material in which a wire material is wound into a coil shape is roughly classified into two methods, that is, a lateral direction and an axial direction, depending on a direction in which the wire material is fed. Each of these two methods generally has the characteristics shown in Table 1. Taking into account the advantages and disadvantages, any one of the methods according to the purpose is adopted.

[0003]

[Table 1]

[0004] Since an increase in the processing speed has a beneficial effect, an axial feed-out method capable of high-speed feeding and continuous operation of the filament material is often used. As shown in Table 1, there are various problems, and various measures have been taken to improve the feeding speed. For example, as shown in FIG. 5, the flyer 1 is rotated to remove one turn of the wire material 2 </ b> A from the winding bundle 2.
There is a device that stabilizes the feeding of the filament by lifting the wire in the axial direction.

However, in the conventional example shown in FIG.
When the winding state of the winding bundle 2 is poor, the winding bundle 2
(A phenomenon in which the wire 2A becomes larger than the winding diameter of the wire bundle 2) and squeezing (the wire 2A is pulled out of the wire bundle 2).
When the bulge occurs, a few turns of the wire material 2A enter the end portion 1A of the flyer 1 and cannot be fed out, resulting in squeezing. In this case, the flyer 1 may be deformed.

If the wire material is entangled or caught during the unwinding, the wire material is cut off because the wire processing device is operating while the unwinding of the wire material is stopped.
If a wire break occurs, it is necessary to pass the wire through the wire rod processing device again, which lowers the work efficiency.At the same time, depending on the mass specification of the processed product, it may lose its value as a product. .

In order to solve such a problem, as shown in FIG. 6, before the wire 3A is supplied from the flyer 4 to the wire processing apparatus, wire tension detection for detecting the feeding property of the wire 3A is performed. The tension of the filament material is constantly measured by the part 5. When the tension is increased, the rotary table 6 receiving the winding bundle 3 is rotated in a direction to assist the feeding of the filament material, thereby stabilizing the feeding property of the filament material. There is a configuration that is adapted to do so.

However, in the conventional example shown in FIG. 6, at the timing when the table 6 is rotated at the time when the tension abnormality is detected by the wire tension detecting section 5, the speed of feeding the filament is increased. In the case or when the winding condition is poor, the problem that several turns of the wire material 3A enter the end portion 4A of the flyer 4 has not been solved yet.

Therefore, although not shown, the table receiving the winding bundle is rotated, and the wire is unwound by applying an advancing force in the lateral direction and is unwound in the axial direction. There is a technique in which the wire is unraveled by its own weight and the twist is released. Further, in order to enable continuous processing by connecting the filament materials, as shown in FIG. 7, the winding guide 7 is fixed in a horizontal state, and is set on the winding guide 7. A flipper-type wire feeder has also been developed in which a wire is drawn out of the winding bundle 8 in the horizontal direction and sent out to a wire processing device or the like via a feeding guide 9.

[0010]

However, according to the above-mentioned prior art, when the diameter of the winding bundle material changes, or when the winding shape is poor due to load collapse due to annealing or the like, this winding bundle material is not used. Since the rotation speed of the receiving table cannot be synchronized with the processing speed of the linear material, it is not possible to stabilize the feeding of the linear material, and the continuous processing is performed by connecting the linear material. There is also a problem that cannot be done.

Further, in the flipper-type wire material feeding device shown in FIG. 7 for performing continuous processing by connecting the wire materials, when the winding state of the winding bundle material 8 is poor,
A few turns of the wire material protrude from the winding guide 7, and (I)
As shown in (2), there were drawbacks such as entanglement by the feeding guide 9, and as shown in (II), the winding guide 7 was deformed by drawing in the wire material.

[0012]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned conventional problems. Even if the shape of the winding bundle material or the annealed material is poor, the wire shape can be improved. The purpose of the present invention is to provide a material in which the feeding property of the strip material is made constant and the speed can be increased, and the gist of the invention is to extend from a winding bundle material set in a winding guide on a turntable in its axial direction. This is a method of feeding out a wire and feeding the wire to a wire processing device. When the feeding speed of the wire is higher than the processing speed of the wire processing device, a bulge of the fed wire is detected. By increasing the processing speed of the wire rod processing device from the present, by returning the processing speed of the wire rod processing device at the time when the bulging is eliminated, or by reducing the feeding speed of the wire rod from the present, the bulging At the time when the In feeding method and device interface member characterized by continuously performing the thereby returning the speed out.

Reference numeral 22 denotes a winding bundle material in which a wire material is wound in a coil shape, and is set on two winding guides 23, 23 described later mounted on the upper surface of the turntable 14, respectively.

Since the two winding guides 23 have the same structure and operation, only one of the winding guides 23 will be described below.
It is fixed upright at the center of the upper surface, and its upper half is formed in a truncated cone shape. At the same time, it is divided into two by a vertical groove 24 on its diameter line, and is provided at the center of the lower surface.

The detector 27A is configured to bend a part of a bar having elasticity into a substantially rectangular shape, and to form a right and left portion. One end of the longer bar is connected to the winding guide 2 so that the corners C, C slightly protrude from the outer peripheral surface of the winding guide 23.
When fixed to 3, the short other end is a free end. Then, when the left and right corners C, C are displaced inward each other by the narrowed wire material (wire material having a reduced diameter), a stop signal is transmitted.

Reference numeral 29 denotes a wire remaining amount detector, which is provided to detect the remaining amount of the winding bundle 22 and obtain a time for replacing the new and old winding bundles. A semiconductor light-emitting element L and a semiconductor light-receiving element F are respectively arranged at opposing positions on a straight line passing through the outer peripheral portion of the wire 22, and a wire material is fed out from the winding bundle material 22 between the two elements L and F and remains. When the quantity no longer exists, the light from the light emitting element L enters the light receiving element F and a remaining amount signal is transmitted.

Reference numeral 30 denotes the winding guide 23 (turntable 14).
And a structure in which an elastic wheel 32 made of rubber or the like fixed to the rotating shaft of a driving motor 31 is brought into contact with the lower surface of the turntable 14 supporting the winding guide 23. It is installed in. Reference numeral 33 denotes a tilting cylinder of the winding guide 23, one end of which is fixed to the turntable 14 and the other end of which is fixed to the lower surface of the side plate 11. In the figure, 34 is a guide pole, 35 is a movable body provided on the guide pole 34 so as to be able to move up and down, 36 is a cylinder for raising and lowering the movable body 35, 37 is a guide hole, and 38 is a guide roller.

Next, the operation of the above embodiment will be described. The winding bundle material 22 is set on each of the two winding guides 23, and one of the winding guides 23 is located on the side of a wire processing apparatus (not shown). When the winding bundle 22 is set on the winding guide 23, the turntable 14 is lifted up by a predetermined angle about the shaft 15 as a fulcrum by the tilting cylinder 33, and the winding guide 23 is tilted.
Is inserted, and the turntable 14 is returned to the original position again.

Therefore, the leading end of the wire rod 22A pulled out from the winding bundle material 22 located on the wire rod processing device side is connected to a wire rod insertion portion of the wire rod processing device via a guide hole 37 and a guide roller 38. . And the winding guide 23
Is rotated in synchronism with the wire processing speed of the wire processing device by an elastic wheel 32 rotated by a drive motor 31, whereby the wire 22 </ b> A is laterally fed out from the winding bundle 22, and then axially. It is pulled up and sent to the wire rod processing device. In this way, by feeding out the filament material 22A in the axial direction from the lateral direction, it is possible to stably feed at high speed even when the winding state is poor.

Here, since the winding state of the winding bundle 22 is poor, the wire member 22A drawn out from the winding bundle 22
May suddenly become larger (swell) than the steady value. In this case, the expanded wire member 22A comes into contact with the detecting portion 28A of the wire swelling detector 28, and the detecting portion 28A
, A brake mechanism (not shown) operates. As a result, the number of rotations of the winding guide 23 is reduced, and the linear material 22 fed from the winding bundle 22 is reduced.
Control is performed to eliminate the bulge of A.

Depending on the contact time and frequency, the swelling of the wire member 22A can be rapidly reduced by reducing the rotation of the winding guide 23 to near the stop. When the bulge disappears and returns to a steady value, the wire bulge detection signal disappears, so that the brake mechanism is deactivated, and the winding guide 23 rotates smoothly again in synchronization with the wire processing speed of the wire processing device.

Also, contrary to the above case, the winding bundle 22
When the diameter of the linear material 22A drawn out from the wire becomes smaller than the steady value (squeezed), the right and left corners of the detecting portion 27A of the linear material narrowing-down detector 27 are determined by the narrowing force of the linear material 22A. C and C are displaced inward from each other, and an aperture signal is generated. Then, the rotation speed of the winding guide 23 is increased by the throttle signal, and the diameter of the wire material 22A is controlled to return to a steady value.

As described above, when the diameter of the fed wire material 22A starts to return to the steady value, the throttle signal disappears, and the rotation speed of the winding guide 23 returns to normal. In addition, when the generation time of the drawing signal becomes long and the wire is likely to be broken, a stop signal is transmitted from the wire drawing detection device 27 to the wire processing device, and the work is temporarily stopped. It is also possible to prevent disconnection.

Next, the case where continuity is provided between the winding bundle 22 being fed and the winding bundle 22 of the other winding guide 23 which is a spare will be described. When the remaining amount of 22 becomes low,
The control is performed so that the next operation is performed within a predetermined time after the wire remaining amount detector 29 operates. That is, the rotation of the drive motor 31 is stopped by the operation of the wire remaining amount detector 29, and the rotation of the winding guide 23 is also stopped. As a result, the wire is fed out only by the pulling force of the wire processing device, and the work described later is performed within the predetermined time.

When the wire rod remaining amount detector 29 detects that the remaining amount of the winding bundle 22 set in the winding guide 23 has decreased during the feeding, the rear end of the winding bundle 22 during the feeding. The connection between the unit and the tip of the spare winding bundle 22 is performed, and the rotary base 10 is immediately rotated by the turning motor 20 to process the winding guide 23 on which the spare winding bundle 22 is set. Locate on the device side.
As a result, the replacement work of the new and old winding bundles is completed, and thereafter, by repeating the same work, the filament can be continuously fed to the wire processing apparatus.

In the case where the feeding speed of the winding bundle 22 is high at the time of detecting the remaining amount by the wire remaining amount detecting device 29, the processing speed of the winding guide 23 and the wire processing device is reduced to reduce the wire speed. The above replacement work can be easily performed without stopping the processing device. In addition, the monitoring operation can be omitted by alerting the wire operator of the decrease in the number of the winding bundles 22 by the remaining amount detection signal.

[0030]

Since the present invention has the above configuration,
Even in the case of a winding bundle material having a poor winding shape, such as an annealed material, it is possible to continuously and stably draw out the filament material from the winding bundle material, thereby improving the operating efficiency of the wire processing apparatus. Are improved.
