BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire drawing structure for a wire such as a welding wire, a spring wire, and a piano wire wound and laminated in a pail container, and more specifically, to reduce the wire drawing resistance. At the same time, the present invention relates to a structure for pulling out a pail winding wire that can be smoothly drawn out.

[0002]

2. Description of the Related Art A pail winding wire is formed by winding and stacking a wire inside a pail winding container. For example, in the case of a pail winding welding wire, when the welding wire is continuously drawn out during welding work. In addition, extra coil-shaped wires bounce up in the upper space of the container and are entangled with each other, or when the bounced wire and the drawn wire are entangled with each other, the wire is twisted at the entrance portion of the drawing device and becomes a kink state, You may not be able to withdraw. For this reason, as shown in FIG. 6, the entire wire laminating surface 55 of the wire coil is pressed by the annular wire pressing member 51 to prevent the pulling wire 54 from jumping up (Japanese Patent Publication No. 59-8474).

The inner diameter 52 of the wire pressing member 51 is formed smaller than the inner diameter 56 of the drawing wire coil 54, and the drawing wire 54 is drawn along the inner peripheral edge 53 of the drawing hole. I am trying.
Then, the wire pressing member 51 is provided with a slight gap between the wire holding member 51 and the outer casing of the pail container, and the wire pressing member 51 is sequentially lowered as the wire is reduced.

[0004]

However, in the above wire drawing structure, it is possible to prevent the extra coil-shaped wire 54 from jumping up into the upper space in the container, but the wire pressing member 51 is larger than the inner diameter 56 of the wire coil. Since the inner diameter 52 is small, a bending force acts on the pull-out wire 54 with the inner peripheral lower end portion 53 of the wire pressing member 51 as a fulcrum. This bending force may increase the pullout resistance of the pullout wire 54, and as a result, the wire may not be smoothly pulled out.

Therefore, as shown in FIG. 5, the inner diameter 52 of the wire pressing member 51 is made larger than the inner diameter 56 of the wire coil so that the drawing wire 54 does not come into contact with the lower end portion 53 of the inner circumference of the wire pressing member 51. It is conceivable to reduce the pull-out resistance of the pull-out wire 54, but in this case, the wire 54 inside the inner diameter of the wire pressing member 51 jumps up to the upper space as a whole, and eventually the above-mentioned Such drawing wires may be entangled with each other.

The present invention has been made in order to solve the above-mentioned conventional drawbacks, and its purpose is to prevent the winding and laminating wires from jumping up while lowering the drawing resistance of the drawing wire. , Without tangling the wires
An object of the present invention is to provide a pail winding wire drawing structure that can be drawn smoothly from a pail container.

[0007]

SUMMARY OF THE INVENTION Therefore, the pail winding wire drawing structure of claim 1 is a pail winding wire drawing structure for drawing the drawing wire 3 wound and laminated in the pail container 1 from the pail container 1. An annular wire pressing member 4 and a weight 5 are arranged in the pail container 1, the annular wire pressing member 4 is placed on the laminated surface 6 of the drawing wire 3, and the inner diameter 8 thereof is the inner diameter of the coil of the drawing wire 3. 7, the lead wire 3 is inserted into the guide hole 9 formed in the weight 5 in the lead-out path of the wire 3, so that the lead-out wire 3 is moved downward from the laminated surface 6. It is characterized in that it is pulled out upward after being derived.

Further, in the pail wound wire drawing structure of the second aspect, the weight 5 is made of a material such as porcelain stone, plastic, metal, etc., which has good sliding property and does not damage the drawing wire 3.

[0009]

In the pail wound wire drawing structure of the above-mentioned claim 1, when the drawing wire 3 is drawn out, the weight 5 inside the drawing wire 3 is stacked, the weight 5 draws the drawing wire 3 and the laminated surface 6 of the wire coil. It guides you to a position lower than that while drawing a circular orbit. As a result, the contact force of the drawing wire 3 to the inner peripheral edge lower end 10 of the annular wire pressing member 4 is reduced, the wire drawing resistance is reduced, and the drawing wire 3 can be drawn smoothly. Drawer wire 3
Is temporarily pulled out by the weight 5 toward the bottom of the pail container, so the lever action with the inner peripheral edge of the laminated surface 6 of the wire coil as a fulcrum will push up the annular wire pressing member 4 to the pull-out wire 3. The force to act does not break other coil layers and entanglement does not occur. Further, since the laminating surface 6 of the wire coil is located within the pressing surface of the annular wire pressing member 4, only the drawn wire is drawn out with a substantially constant resistance, so that entanglement due to the drawing does not occur.

In the pail wound wire drawing structure of the second aspect, the frictional resistance is reduced and the drawing can be carried out more smoothly.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A concrete embodiment of the pail winding wire drawing structure of the present invention will be described in detail with reference to the drawings. 1 to 4 show an embodiment of the present invention.

Reference numeral 1 is a pail container, and 2 is an outer cylinder thereof. Inside the outer cylinder 2, a drawing wire 3 is wound in a coil shape and laminated, and an annular wire pressing member 4 and a weight 5 are arranged. The annular wire pressing member 4 is placed on the laminating surface 6 of the wound and laminated wire coil. The annular wire pressing member 4 has an inner diameter 7 of the wire coil wound and laminated in the above coil shape.
The outer diameter of the annular wire pressing member 4 is slightly smaller than the inner diameter of the outer cylinder 2. The gap between the annular wire pressing member 4 and the outer cylinder 2 is such that the annular wire pressing member 4 can move in the outer cylinder 2 in the axial direction without resistance, but the pull-out wire 3 cannot jump up from the gap. I am doing it.
Suitable materials for the annular wire pressing member 4 include wood, hard board, paper, and plastic, but are not limited to these.

A guide hole 9 is bored in the weight 5, and the wire 3 being pulled out is inserted into the guide hole 9. The weight of the weight 5 is such that even if the pull-out wire 3 is suddenly pulled upward, it is not pulled upward together with the pull-out wire 3 due to the frictional resistance between the guide hole 9 and the pull-out wire 3. In addition, the pull-out wire 3 has a weight such that the pull-out wire 3 is once pulled out from the laminated surface 6 of the wire coil and then pulled out upward, for example, 60 g or more. The guide hole 9 is eccentrically located. The lead wire 3 is led out from the guide hole 9. Guide hole 9
Is sufficiently large that it does not hinder the pull-out wire 3 from passing through, and the inside of the hole and both ends of the inlet and outlet are processed smoothly. The material of the weight 5 is preferably glass or the like such as an insulator, but is not limited to this, and the number may be two or more.

Next, the operating state of this embodiment will be described. When the pull-out wire 3 is pulled out upward, the guide hole 9 of the weight 5 is introduced.
Since the pull-out wire 3 is derived from the
It does not move upward together with the pull-out wire 3 due to its own weight, and as shown in FIG. 3, it is located at a position lower than the laminating surface 6 of the wound and laminated wire coil,
Alternatively, it is in contact with the inner peripheral edge portion 10 of the annular wire pressing member 4. When the pull-out wire 3 is pulled upward,
The weight 5 moves in the direction of the arrow 11 shown in FIG. 4, that is, in the direction opposite to the direction in which the extraction wire 3 is wound. At this time, the pull-out wire 3 is once pulled out below the laminated surface 6 of the wire coil due to the weight of the dead weight 5, so that the pull-out wire 3 is moved by the lever action with the inner peripheral edge portion of the laminated surface 6 of the wire coil as a fulcrum. Since the force acts in the direction of pushing up the annular wire pressing member 4, the other pull-out wires 3 are not broken and entanglement does not occur. Further, since the laminating surface 6 of the wire coil is located within the pressing surface of the annular wire pressing member 4, only the drawn wire is drawn out with a substantially constant resistance, so that entanglement due to the drawing does not occur. Further, the drawing wire 3 is connected to the inner peripheral edge portion 1 of the annular wire pressing member 4.
Since the force of contacting 0 is also reduced, the pull-out resistance of the pull-out wire 3 can be reduced and the pull-out wire 3 can be smoothly pulled out.

[0015]

As described above, in the pail-wound wire drawing structure according to the first aspect of the present invention, in addition to being able to reduce the drawing resistance of the drawing wire, it is possible to prevent the wire from bouncing and entanglement, and therefore the drawing wire. Can be pulled out smoothly.

According to the second aspect of the present invention, it is possible to more smoothly draw the wire without damaging the surface thereof.
