Abstract

PROBLEM TO BE SOLVED: To suppress tensile force for feeding out a wire material below specific tensile force by constituting a wire material feeding out device in such a manner that a rotary base which can set a bobbin or a drum in such a manner that it is put transversely is supported on a shaft in the longitudinal direction and the shaft is linked to a base through an angle adjusting mechanism so that the rotary base can be tilted. SOLUTION: Since a bobbin or a drum 1 is put transversely, a bolt for adjusting angle 9 is rotated to adjust the inclination of an angle adjusting plate 9' when crumbling of winding is likely to occur when a wire material 5 is fed out so that the inclination of a rotary base 7 is changed. By setting the inclination of the bobbin or drum 1 in the orthogonal direction to the direction of wire material feeding but A, it is possible to suppress the crumbling of the wound wire material. Consequently, even when feeding out of the wire material is started and activated when tensile force for feeding out wire material increases, it is possible to suppress the tensile force below about 2 kgf.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire feeder for feeding a wire such as a copper wire.

[0002]

2. Description of the Related Art Conventionally, a wire material, particularly a copper wire, has been wound around a bobbin and a drum, and the required feeding has been performed by a so-called vertical setting device in which the axes of the bobbin and the drum are set horizontally. .

FIG. 3 shows a conventional wire feeder, in which a shaft 4 is attached to a stand-type feeder main body 2.
And the bobbin or drum 1 is mounted on the shaft 4. Reference numeral 3 denotes a rotating bracket for assisting the rotation of the bobbin or the drum 1 on the shaft 4.

The reason why the bobbin or the drum 1 is set vertically as described above is to prevent the wire wound around the bobbin or the drum 1 from being broken; In this case, the bobbin or the drum 1 can be easily set on the delivery device main body 2.

[0005] In the above wire feeder,
In some cases, a bearing 6 as shown in FIG. 4 is attached to a shaft section around a bobbin or a drum in order to minimize the load when the wire is fed out and to enable smooth wire feeding.

[0006]

FIG. 3 (FIG. 4) has the following problems.

For example, assuming that the mass of the bobbin or drum and the mass of the wire are 500 kg in total, the wire feeding device described above has a feeding tension of 2.5 to 3.5 kg.
f is the limit and cannot be used in equipment that can only provide a tension less than this. This is because the bobbin or drum and the shaft receiving the load of the wire and the rotating shaft are the same, and all the load is applied to the bearing portion for smooth rotation.

As the above countermeasure, there is a case where the feeding tension is reduced by reducing the winding amount of the wire rod, but the frequency of replacing the bobbin and the like increases, and the working efficiency is negative.

In the above-mentioned wire feeder, since the wire feed tension is large, when the wire is a copper wire having a small diameter, the wire diameter may be reduced during use. In particular, when the wire feed speed and the rotation of the bobbin or the drum are not synchronized, an excessive tension is applied to the wire intermittently, and the wire diameter tends to be thin.

Therefore, the problems to be solved by the present invention (objects)
An object of the present invention is to provide a wire feeding device capable of suppressing the wire feeding tension to 2 kgf or less.

[0011]

A wire feeder provided by the present invention supports a turntable on which a bobbin or a drum can be set sideways on a vertical shaft, and the shaft is connected to a base via an angle adjusting mechanism. And the turntable can be tilted.

[0012] As described above, the bobbin or the drum is placed in a horizontal position, and the shaft receiving the load of the wire and the bobbin or the drum is erected. Without,
The wire can be sent out with low tension.

[0013] To prevent the winding collapse caused when the bobbin or the drum is placed sideways when the wire is fed out, the angle adjustment mechanism adjusts the depression angle or the elevation angle with respect to the direction perpendicular to the wire feeding direction of the turntable. As a result, the inclination of the bobbin or the drum is adjusted, and thus the collapse of the wire as described above is suppressed.

The angle adjusting mechanism includes a universal joint provided between a lower end of the shaft and the upper surface of the base, an angle adjusting plate fixed to the shaft, and a screw mounted on each of the adjusting plates and mounted on the base. It is preferable to use an angle adjusting bolt implanted in the horn.

Alternatively, the angle adjusting mechanism may comprise a tilting arm extending substantially L-shaped on the base, and a lower end of the shaft may be connected to a tip of the tilting arm.

If two or more bearings are installed on the shaft at a position for receiving the bottom of the turntable, the turntable can be rotated more smoothly.

In order to make the wire feeding with a low tension as described above more feasible, the condition of the bobbin or the drum must be a flange diameter (outer diameter) of 1000 mm.
Below, the total mass of the wire and the bobbin or drum is 700
It is desirable that the weight be less than kg.

[0018]

FIG. 1 shows a first embodiment of a wire feeder according to the present invention, wherein (a) shows a front view and (b) shows a plane.

The wire feeder of the first embodiment comprises a disk-shaped turntable 7 on which the bobbin or drum 1 is set sideways, and a vertical shaft 8 which supports the turntable 7.
And a shaft 8 and a base 10 for supporting the entirety.

However, the lower end of the shaft 8 is
On the other hand, an angle adjusting plate 9 ′ is attached to the shaft 8, and the angle adjusting plate 9 ′ is screwed at a plurality of positions at the same distance from the shaft 12. It has an adjusting bolt 9, which is implanted in a standing state on a base 10, so that the upper end of the shaft 8 can be freely tilted by the universal joint 12, and the angle adjusting plate 9 And the angle of the shaft 8 can be adjusted to be constant by adjustment using the angle adjustment bolt 9.

Further, two bearings 6 are installed at positions where the rotary table 7 is received on the shaft 8 so that the rotary table 7 can be smoothly rotated.

According to the wire feeder configured as described above, the bobbin or drum 1 on which the wire 5 is wound is set upside down (the axis is in the vertical direction) on the turntable 7, and FIG. As shown in (b), the wire 5 is fed in the direction A, and at this time, the turntable 7 rotates in the direction B.

When the bobbin or the drum 1 is laid horizontally, when the wire 5 is likely to be easily broken during feeding, the angle adjusting bolt 9 is rotated as shown in FIG. The inclination of the turntable 7 is changed by adjusting the inclination of the angle adjusting plate 9 ′, thereby setting the inclination of the bobbin or the drum 1 in a direction orthogonal to the wire feed direction A, thereby winding the wire. Deter the collapse.

Table 1 shows the results of measuring the wire feeding tension of the wire feeding device according to the above embodiment. A comparative example is a conventional wire feeder; FIG. The measurement conditions are as follows. Wire: copper wire, wire diameter: 4.85mm,
Wire mass: 400 kg, bobbin mass: 110 kg.

[0025]

[Table 1]

As is evident from Table 1, especially at the start of wire feeding when the wire feeding tension becomes large; even at the time of start-up, in the present embodiment, it is suppressed to 2 kgf or less, and the intended purpose can be achieved. did.

FIG. 2 shows a second embodiment of the wire feeder according to the present invention. In the wire rod feeder of this embodiment, a rotary table 7, a vertical shaft 8, and a bearing 6 for setting a bobbin or a drum 1 are the same as those in the above-described embodiment: FIG. As a mechanism, a tilting arm 11 extending substantially in a horizontal L shape on a base 10 is used, and the lower end of the shaft 8 is connected to the tip of the tilting arm 11.
This means that the tilt of the turntable 7 is adjusted by the elevating movement of the arm 11.

[0028]

According to the present invention as described above, the feeding tension of the wire can be suppressed to 2 kgf or less.
Expected problem of providing wire feeder (purpose)
Can be achieved.

According to the wire feeder of the present invention, even with equipment such as a header processing machine having a small feed tension, high-efficiency work can be performed without reducing the winding amount. In addition, even for a wire having a small diameter, the tension at the time of feeding the wire can be small, so that it is possible to prevent the wire diameter from being reduced at the time of feeding the wire.

Further, it is also possible to use a bobbin or a drum which could not feed a wire in the prior art, and it is possible to increase the size of the material package, reduce the frequency of material switching, and improve the working efficiency. In particular, even a bobbin in which a copper wire having a wire diameter of 4 mm or more is wound by 400 kg can be stably fed with a feeding tension of 2 kgf or less. And so on.
