As described above, the configuration of the guide roller 4 is described.

The present invention constituted as described above is composed of a plurality of the bobbin mounting and brake means (2) and the tension head portion (3) and the guide roller (4) for the supply.

In addition, T, which is not described among the reference numerals in FIG. 6, is a twisting machine for twisting a plurality of wire rods.

Referring to the operation of the present invention configured as described above are as follows.

First, the operation of the embodiment of the present invention will be described. The bobbin mounting and brake means 2 take out the wire rod S from the bobbin 22 and supply it to the upper side, and to the supply tension head portion 3. By the tension is adjusted by the guide roller portion 4 is sent to the twisting machine (T).

That is, the specific description of the above operation is as follows.

As shown in Figs. 1, 2 and 6, the wire rod S for wire is drawn out from the bobbin 22 to the supply tension head portion 3, the guide roller portion 4 and the twisting machine T. After the hypothesis, the twisting machine T is twisted while pulling a plurality of wire rods S.

At the same time, when the motor 5 is driven, the magnetic plate 6 formed on the motor shaft 6 is rotated, and the friction plate 10 including the copper plate 9 is rotated by the magnetic force of the magnetic plate 6 to rotate the friction plate 10. When the friction plate 10 is rotated, the rotating shaft 8 is rotated.

As the rotary shaft 8 rotates, the brake 11 and the bobbin shaft 12 rotate, and as the bobbin shaft 12 rotates, the wire rod S wound around the bobbin 22 is unrolled to form a frame. It feeds to the supply tension head part 3 comprised in the upper part of the frame 1.

The wire rod S transferred to the tension head 3 for the supply is sequentially supported by the support guide roller 32 via the first, second and third guide rollers 30, 31, 35. It is guided and conveyed to the guide roller part 4 via the delivery guide roller 37.

The wire rod S transferred to the guide roller part 4 is guided to the twisting machine T according to the guide of the roller 52 to make a twist.

As described above, the tension adjusting device of the wire wire feeder of the present invention, which transmits the wire wire S to the twisting machine T, as shown in FIG. The tension wire is normally maintained by (3), and the wire S for wires sent out in such a state has a good twisting by the twisting machine T.

However, when the wire for wire (S) to be sent out abnormally loosened in this case, the lever bracket 26 is pulled downward to the center of the shaft 25 by the tension force by the tension spring 42, so the bracket for the lever ( 26, the front portion descends downwardly and the rear portion rises upwardly about the shaft 25.

In this case, the brake bar 19 coupled to the rear tip portion is raised upward.

In addition, the bearing-type rotating body 27 installed on the shaft 25 is in contact with the eccentric cam 29 to rotate, and accordingly the roller support rod 34 coupled to the eccentric cam 29 is put aside back and its upper side. The third guide roller 35 installed at the tip end is also pulled backward so as to pull the wire rod S.

At this time, tension is generated between the guide feeding roller 37 and the twisting machine T, through which the wire wire S is sent, and at the same time, as the brake bar 19 is raised upward, FIGS. 2 and 5. As in the brake pad 17 is to control the brake (11).

In this case, the bobbin shaft 12 is controlled to temporarily stop or reduce the number of revolutions. At this time, the loosening of the wire rod S from the bobbin 22 is controlled so that the wire rod S maintains a normal tension. Will be sent to.

The reason for being able to pause the bobbin shaft 12 or reduce the number of revolutions by controlling the brake 11 is that the magnetic plate 7 of the motor shaft 6 and the friction plate 10 to which the copper plate 9 is attached. The friction plate 10 is rotated by the suction force of the magnetic plate 7 in a state where the spaced apart from each other.

However, when the brake 11 is controlled, the control force is designed to be larger than the suction force of the magnetic plate 7, so that even if the magnetic plate 7 rotates at the normal rotational speed, the friction plate 10 may be temporarily or reduced. It will be possible.

Therefore, the rotation of the bobbin shaft 12 connected to the friction plate 10 and the rotation shaft 8 is to be controlled.

On the other hand, when the wire for the wire (S) is maintained in the normal tension as described above and the tension is abnormally high in the wire for the wire (S) when the tension is the third guide roller 35 and the roller support rod (34) To the front and in this case, the brake 11 which was operated by the brake pad 17 in the reverse order of "adjusting to the normal tension when the wire rod S sent out abnormally loosened" was controlled. Release it.

At this time, the number of revolutions of the bobbin shaft 12 is increased, and the wire rod S for wires also increases the unwinding speed from the bobbin 22 and is sent out while maintaining a normal tension.

Tension adjusting device 40 of the present invention is to adjust the magnitude of the tension of the wire (S) for the wire is sent.

That is, when the knob 46 is rotated in FIGS. 2 and 4, the adjusting bolt 45 is rotated and the adjusting hole 43 is controlled by the stopper 49 to be rotated by a predetermined distance in the vertical direction to the lower side. Descends.

In this case, the tension spring 42 has a large tensile force, the tension force is a force to pull the bracket 26 for the lever acts to rotate about the axis 25 is generated.

In this case, the eccentric cam 29 in contact with the rotating body 27 has a rotational force acting in the opposite direction of the rotating body 27 so that the third guide roller 35 of the roller support rod 34 is also rearward. The force that is put aside increases.

In this state, since the twisting is performed while pulling the wire rod S in the twisting machine T in FIG. 6, the tension is increased in the wire rod S sent.

On the other hand, in order to lower the tension on the wire for the wire (S), the knob 46 of the tension control port 40 may be rotated in the opposite direction.

Description of the operation for this is made in the reverse order of the operation in the case of increasing the tension on the wire (S) for the wire in the above.

The present invention as described above is to improve the twisting to be sent in a state that maintains a uniform tension without stretching or breaking when sending the wire (S) of the multiple wires to the twisting machine (T). .

1 and 6, the frame frame 1 is tapered in a shape of a back light narrow, i.e., wider from front to rear, and bobbins on both sides of the frame frame 1 By mounting and mounting the brake means 2, the tension head part 3 for supply and the guide roller part 4 in a double configuration, more wire rods S for the electric wire of the guide roller part 4 are formed. (52) Phenomena that is supplied in a state of minimizing the transmission angle (θ) when it is sent to the twisting machine (T) to improve the twisting of the wire rod (S) for wires and smoothly supply the phenomenon of easy disconnection Can be prevented.

In addition, the present invention, even if the configuration for sending the wire for the wire (S) as described above by double configuration on both sides of the frame frame (1) mounting more bobbin 22 to send a lot of wire for wire (S) The frame frame 1 is not bulky and takes up less place in the workplace.

The present invention as described above is to improve the twisting by sending the wire (S) for the wire to the twisting machine (T) in a uniformly maintained state of tension without sagging or breakage, or the present invention As a characteristic of the ultra-precision diameter (0.03mm ~ 0.05mm) wire wire for wire can be drawn out and sent to the twisting machine without being cut as described in detail as follows.

That is, as shown in FIG. 2, the support guide roller 32 is installed upward by the roller bar 36 at the tip of the support bracket 24 in the supply tension head section 3, thereby providing a third guide roller ( The wire swivel wire guided to the support guide roller 32 is widened at the same time as the angle θ ₁ (25 ° to 30 °) of the wire rod S transferred to the support guide roller 32 from 35. The angle of (S) forms a gentle angle.

In addition, the second guide roller 31 is provided at the tip of the bracket 26 for lever to transfer the wire rod S for electric wire from the second guide roller 31 to the third guide roller 35. An angle θ ₂ (20 ° to 25 °) of the wire S for electric wires transferred from the second guide roller 31 to the third guide roller 35 is also widened.

Therefore, the frictional force is minimized and the wire rod S for the wires S transferred and guided through the first, second and third guide rollers 30, 31, 35 and the support guide rollers 32. ) The load on) is minimized so that even wire rods with ultra-precision diameters (0.03㎜ ~ 0.05㎜) can be drawn out and sent to twisting machine without being cut.
