DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for traversing a linear object of a winding machine for winding a linear object around a bobbin.

[0002]

2. Description of the Related Art Conventionally, when a linear object is wound on a take-up bobbin, as shown in FIG. 4, a ball screw shaft 31 disposed close to the bobbin 30 and parallel to the bobbin shaft is provided with a traverser 32.
Is fitted movably in the axial direction, the traverser 32 is reciprocated by rotating the shaft 31 by a motor 33,
A method is adopted in which lit switches 34 and 35 are provided at the reversing positions a and b to control the reversal of the traverser 32 to traverse the linear object W.

[0003]

In the above-mentioned conventional method, when the winding of the linear object W is switched from one full bobbin 30 to the other empty bobbin, one flange portion 36 of the empty bobbin 30 is used. The linear object W is hooked onto the claw 38 attached to the side drum 37 and wound up. During this time, the linear object W is wound around the same portion in the vicinity of the flange 36 on the claw 38 side, though it may not be short. As a result, there is a problem that the winding shape is biased due to the swelling and the shape becomes non-uniform. Therefore, the bias of this shape is
The operator must manually correct the traverser by inverting the traverser, which is very inefficient.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has as its object to automatically correct the deviation of the winding shape which occurs at the initial stage of winding a linear object to thereby achieve uniform winding. It is an object of the present invention to provide a method of traversing a winding machine which enables the winding.

[0005]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, the present invention is a method for traversing a linear object of a winding machine, in which a linear object is guided to a bobbin by a traverser reciprocating in the axial direction of the bobbin so as to be wound uniformly, and Immediately after the winding switching, a reversing position for correction is set closer to the center of the bobbin than the original reversing position, and the traverser is reciprocated a required number of times between the reversing position for correction and the reversing position on the opposite side. , Which is characterized by reversing movement between the original reversing positions.

[0006]

According to the present invention, in the initial stage of switching from a full bobbin to an empty bobbin, a linear object is traversed only a required number of times in a portion except for a portion wound in the same location to correct the deviation in the winding shape. After that, by traversing over the entire range between the original flange portions, a uniform winding shape can be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a bobbin for winding a linear object.
One flange 1A-side drum 2 is provided with a winding start locking claw 3 for the linear material W. When the end of the linear material W is locked to the locking claw 3, winding is started. As shown in FIG. 2, the traverse is started after being wound around the bobbin 1 at the same position.

Reference numeral 4 denotes a traverser for the linear object W,
The ball screw shaft 5 is disposed so as to be reciprocable in the axial direction so as to be reciprocally movable in the axial direction. The screw shaft 5 is driven by a traverse motor 6 to rotate forward and reverse. A pulse detector 10 for detecting a traverser position is attached to the screw shaft 5 via pulleys 7, 8 and a belt 9.

Reference numerals 11 and 12 denote traverser inversion position detectors (for example, limit switches, proximity switches, etc.)
The first traverser 4 is disposed so as to correspond to the two flange portions 1A and 1B, and substantially sets the normal reversal positions a and b of the traverser 4 and the range LN thereof. Reference numeral 13 denotes a traverser control device, which receives signals from the pulse detector 10 and the inversion position detectors 11 and 12 and outputs a command value to the traverse motor 6. Are compared, the command value to the traverse motor 6 is output, and the initial correction range L and the number of traverses thereof are controlled.

The deviation of the winding shape at the beginning of the switching to the empty bobbin 1 is determined based on the width and height empirically obtained based on the wire diameter, the wire speed, and the like, and is set in the traverser control device 13. It is. Then, the position information P obtained from the signal from the pulse detector 10 after the detection and inversion by the inversion position detector 12 of the traverser 4 is compared with the number of correction inversion position setting pulses Ps, and the information P and the number of set pulses Ps are compared. If they match, the traverse motor 6 rotates in the reverse direction, the correction reversal of the traverser 4 is performed, and this correction reversal operation is performed within the set range L and the set reversal number N, and after the bias of the initial winding shape is corrected, The control is switched to the normal traverse range LN.

The traverser control of the above embodiment will be described with reference to the flowchart shown in FIG. 3. The traverser control is started at the same time when the locking or crossover of the linear object W to the empty bobbin 1 is completed. It is checked whether it is started or not, and in step 15 it is determined whether or not the traverser inversion detector 12 can detect the signal. In the next step 17, the number of pulses P is read by the pulse detector 10 (movement distance measurement), and in step 18, a comparison P = Ps between the set number of pulses Ps and the actually measured number of pulses P is performed. In step 19, inversion and inversion traverse at the correction position are repeatedly performed. In step 20, a comparison check is performed between the set reversal number N and the actually measured reversal number Na, and after the correction operation is completed.
In (N = Na), in step 21, a normal inversion traverse by the inversion detectors 11 and 12 is executed.

The present invention is not limited to the above-described embodiment, but may be applied to other devices.

[0013]

As described above, the present invention relates to a method for traversing a linear object in a winding machine in which a linear object is guided and guided by a traverser reciprocating in the axial direction of the bobbin. And, immediately after the winding switch to the empty bobbin,
A correction inversion position is set closer to the center of the bobbin than the original inversion position, and the traverser is reciprocated a required number of times between the correction inversion position and the inversion position on the opposite side. This feature is characterized by reversing and moving, so that the bias of the winding shape caused by bobbin switching can be automatically corrected, and the winding shape can be made uniform. It becomes unnecessary, and work efficiency and productivity can be improved.
