[0002]

2. Description of the Related Art Conventionally, in a wire winding apparatus for winding a wire, as shown in FIG. 3, a wire w is moved in a lateral direction of a winding bobbin 24 (a direction from the front to the back of the drawing, or the reverse direction). And a traverser 25 is fixed in the vertical direction (wire feeding direction) so that the wire w is uniformly wound on the winding bobbin 24. The wire w passes through the traverser roll 22 and the curl diameter adjusting roll 23. When the wire is wound around the winding bobbin 24, the diameter of the wound wire gradually increases to cause "thickening", so that the wire w moves to the winding start position P1.
The winding angle from the entering wire angle β1 to the winding angle β2 at which the wire w enters the winding completion position P2 is constantly changing, and the winding is performed in a state where the angle at which the wire w abuts the curl diameter adjusting roll 23 is constantly changing. Had been.

[0003]

Therefore, in the conventional wire winding apparatus 200, the wire w is moved from the winding angle β1 into the winding start position P1 to the winding completion position P2.
When the wire angle is gradually changed up to the wire angle β2, the wire w wound around the winding bobbin 24 is undesirably “wound”, and when the wire w is pulled out from the wound product bobbin. In addition, "Karami" between wires
It may cause troubles such as. The present invention has been made in order to solve the above-described problems, and has an object to provide a wire winding device that can wind a wire without giving a bad curl to the wire when winding the wire. And

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing the configuration of an embodiment of a wire rod winding device according to the present invention.

As shown in FIG.
Are a guide roller 11, a guide pulley 12, a traverser roll 2, and a curl diameter adjusting roll 3 for guiding a wire w sent from the left side of the drawing by a wire drawing machine or an annealing machine, and a rotation drive source (not shown). ), A winding bobbin 4 for winding the wire rod, a traverser 5 for adjusting a winding state on the winding bobbin 4, a winding diameter control servomotor 7 for controlling the movement of the traverser 5 in the wire feeding direction, and a precision motor. Ball male screw 6a and traverser 5
Is provided with a traverse pitch control servomotor 8 and a precision ball male screw 6b for controlling the movement in a direction perpendicular to the wire feed direction (hereinafter, referred to as “wire feed perpendicular direction”).

The precision ball male screw 6a is screwed with a precision ball female screw 13a provided in the traverser 5 in the wire feed direction, and the winding diameter control servomotor 7 is fixed on a winding diameter motor base 14, The precision ball male screw 6b is screwed with a precision ball female screw 13b provided on the winding diameter motor base 14 in a direction perpendicular to the wire feed.

Therefore, when the traverse pitch control servo motor 8 is driven to rotate in any direction by the above configuration, the precision ball male screw 6b is rotated by the rotation of the motor, and the winding is accordingly performed. The diameter motor base 14 moves back and forth in the direction perpendicular to the wire rod delivery. Winding motor stand 14
The winding diameter control servomotor 7 is fixed on the upper side, and the precision ball male screw 6a connected to the winding diameter control servomotor 7 is screwed with the precision ball female screw 13a of the traverser 5. The traverser 5 also moves forward and backward in the direction perpendicular to the wire rod delivery by the movement of 14 in the direction perpendicular to the wire rod delivery. As described above, by appropriately rotating the traverse pitch control servomotor 8, the wire w can be uniformly and uniformly wound on the winding bobbin 4.

When the winding diameter control servomotor 7 is driven to rotate in either direction, the precision ball male screw 6a is rotated by the rotation of the motor. Precision ball male screw 6
Since a is screwed into the precision ball female screw 13a of the traverser 5, the rotation of the precision ball male screw 6a causes the traverser 5 to move forward and backward in the wire feed direction. As described above, when the winding diameter control servomotor 7 is driven to rotate, as shown in FIG. 2, the traverser roll 2 and the curl diameter adjusting roll 3 installed at the front end of the traverser 5 also move in the wire feeding direction in conjunction therewith. Move back and forth.

For this reason, when the winding diameter control servomotor 7 is appropriately rotated, the angle at which the wire w enters the winding start position P1 of the winding bobbin 4 (the winding of the wire w around the winding bobbin 4). Angle) from the winding start entry angle α1 to the winding completion entry angle α2, which is the angle at which the wire w enters the winding completion position P2 of the winding bobbin 4, and the optimum angle can be set. This set angle can always be kept constant during the winding operation. With this control, the wire w is wound around the winding bobbin 4 so that the diameter of the wire increases and “rolls up”. However, the winding up of the wire w follows a predetermined value at each position. And uniform values can be obtained. For this reason, there is an advantage that a bad curl that causes “entanglement” between wires after shipping the product is not attached.

The traverse pitch control servomotor 8 and the winding diameter control servomotor 7 may be controlled manually by an operator according to the winding state of the wire w, or may be controlled by a sensor or the like. It is also possible to monitor the pick-up status and automatically control it by a computer or the like. Further, each control motor may be simply driven to rotate at a constant speed.

In the above, the traverse pitch control servomotor 8, the precision ball screw 6b, and the winding diameter motor base 1
4, a winding diameter control servomotor 7, and a precision ball screw 6a
The traverser 5, the curl diameter adjusting roll 3, and the traverser roll 2 constitute traverser means or traverse direction control means.

In the above, the winding diameter control servomotor 7, the precision ball screw 6a, the traverser 5, the curl diameter adjusting roll 3, and the traverser roll 2 constitute traverser control means or insertion angle control means. I have. The traverser means and the traverser control means constitute a wire winding control means. Further, in the above description, the curl diameter adjusting roll 3 and the traverser roll 2 constitute a winding control roller.

The present invention is not limited to the above embodiment. The above-described embodiment is an exemplification, and has substantially the same configuration as the technical idea described in the claims of the present invention, and any device having the same function and effect can be realized by the present invention. It is included in the technical scope of the invention.

For example, in the above embodiment, the winding diameter control servomotor 7 for controlling the movement of the traverser 5 in the wire feeding direction is fixed on the winding diameter motor base 14, and this winding diameter motor base 14 is connected to the traverse pitch control servo. Although the example has been described in which the motor 8 controls the movement in the direction perpendicular to the wire rod delivery,
The traverse pitch control servo motor 8 for controlling the movement of the traverser 5 in the direction perpendicular to the wire feed is fixed on a traverse motor base (not shown). May be controlled by the winding diameter control servomotor 7 in the wire feeding direction. In short, any configuration may be used as long as it can freely control the movement of the wire w in both the forward and backward directions of the wire delivery direction and the wire delivery direction.
