BACKGROUND OF THE INVENTION
The present invention relates to a method and an apparatus for aligning and winding a wire around a rotating bobbin.
[0002]
[Prior art]
In the conventional wire winding method, the traverse turn position is manually adjusted in accordance with the width of the bobbin used for winding the wire. This turn position was detected using a sensor or the like.
[0003]
Specifically, as shown in FIGS. 8 to 10, when the bobbin 2 is moving in the left direction, the spring 15 is contracted by the hook 4 hitting the bobbin hook detecting unit 29, and the left reverse position detection sensor 34 is moved. Detect and operate the bobbin 2 to start moving in the right direction. Similarly, even when the bobbin 2 is moving in the right direction, the spring 15 is contracted by the hook 4 hitting the bobbin hook detecting unit 29, the right reverse position detection sensor 35 is detected, and the bobbin 2 is moved to the left. Operate to start moving in the direction.
[0004]
The reverse position detection sensor 34 and the right reverse position detection sensor 35 are pivotally supported by a reverse position detection sensor ball screw 33. The reverse position detection sensor ball screw 33 includes a left reverse position detection adjustment handle 31 and a reversal position detection sensor 31, respectively. A right reverse position detection adjustment handle 32 is attached, and by rotating, both the sensors 34 and 35 can be moved, and the reverse position is adjusted manually.
[0005]
[Problems to be solved by the invention]
In the prior art described above; the wire alignment winding method and apparatus shown in FIGS. 8 to 10, the following points to be improved are found. That is, as shown in FIG. 7, the bobbin 2 has a width L between the widths of the bobbin 2 that is ideally a bobbin having no dimensional deviation. Due to the deformation generated in the above, there is a slight variation in the above-mentioned distance L between the collars.
[0006]
Furthermore, the pitch P, which is the amount of horizontal movement of the bobbin 2, is more affected by the amount of the gap generated at the heel end as the wire diameter D of the wire 5 to be wound is thinner. In an extreme case, the gap G for one wire 5 is generated or eliminated, and the winding may be disturbed. Therefore, it is necessary to adjust the turn position and the pitch P. However, the pitch P is constant regardless of the distance L between the heels, and since the proximity sensor is manually adjusted, it is difficult to reliably set the turn position according to the bobbin. There was a problem that I had to assist.
[0007]
The present invention has been made in view of the above-mentioned problems of the prior art, and its problem is to automatically set the distance between the widths of the bobbins, automatically calculate the pitch according to the bobbin, It is an object of the present invention to provide a method and an apparatus for aligning and winding wires that enable automatic setting.

[0017]
Next, with reference to FIG. 5, a description will be given of the measurement for measuring the bobbin width, the automatic calculation of the pitch, and the control for automatically setting the turn position. As shown in FIG. 5, the control system includes a data input touch panel 23 for inputting wire diameter data of the wire 5, a bobbin horizontal movement amount detection encoder 20 that outputs a pulse corresponding to the horizontal movement amount of the bobbin traverse, The output pulse from the port edge detection side length sensor 13, the starboard edge detection side length sensor 14 and the bobbin horizontal movement amount detection encoder 20 for detecting the flange 4 of the bobbin 2 is converted into a distance and the pitch is calculated. A sequencer 24 for calculation, a bobbin feed motor controller 25 for controlling the feed amount of the bobbin traverse 3 by the pitch, a bobbin feed motor 21 controlled by the bobbin feed motor controller, and a turn position are grasped. This is composed of a bobbin rotation amount detection encoder 10.
[0018]
First, the measurement between bobbin ridge widths is performed as follows. When the bobbin 2 is moved in the left horizontal axis direction by the bobbin feed motor 21, the hook 4 on one side of the bobbin 2 is detected by the starboard edge detection side length sensor 14. At this time, the bobbin in the sequencer 24 is detected. The number of pulses from the horizontal movement amount detection encoder 20 is reset to zero. This data is the data on the starboard side of the bobbin 2. Next, the bobbin 2 is moved in the right horizontal axis direction, and at the same time, pulses from the bobbin horizontal movement amount detection encoder 20 are counted in the sequencer 24. As the bobbin 2 moves to the right, the hook 4 on one side of the bobbin 2 is detected by the port edge detection side length sensor 13 and the movement of the bobbin 2 is stopped. Then, the number of pulses of the bobbin horizontal movement amount detection encoder 20 at this time is stored in the sequencer 24. This number of pulses becomes the data of the port end of the bobbin 2. The cumulative number of pulses counted in the sequencer 24 is converted into a distance (e.g., 100 pulses = 1 cm), and the converted data is corrected for the width of the detection device frame 16 or the like. The distance between the ridges.
[0019]
Next, a pitch conversion method and a turn position detection method will be described with reference to the flowchart of FIG. 6 (and FIG. 7). First, in the sequencer 24, the pitch P is calculated from the distance data between the widths measured above and the data of the wire diameter D of the wire 5 input from the data input touch panel 23. If the pitch P is determined, the number N of windings in which the wire 5 can be wound on the first layer of the bobbin 2 is determined. Next, it is compared whether or not it is within the range of the gap G that can be aligned and wound. The amount of the gap G can be obtained by subtracting the amount of the wire diameter D of the wire 5 from the obtained amount of the pitch P. When the amount of the gap G is not suitable, the amount of the gap G is adjusted by increasing / decreasing the number of windings N, and the pitch P and the number of windings suitable for the bobbin 2 are determined.
[0020]
Next, the turn position detection method will be described. The starboard end position sensor is located at the position where the pulse from the bobbin horizontal movement amount encoder 20 is reset to 0 at the time of measuring the span width. The position of the value obtained by subtracting the width of 13 is the starboard position, and is calculated and set by the sequencer 24. Assuming that the starboard end position is the origin and winding is started, the left width end position is determined by the number N of windings simultaneously calculated during pitch calculation. When the wire 5 is taken up by the bobbin 2, the bobbin 2 measures the rotation amount in the sequencer 24 by the bobbin rotation amount detection encoder 10. When the number of windings N and the rotation amount coincide with each other, it is determined that the port is at the starboard end position, and the bobbin feed motor is reversed. The next starboard position is also detected by the calculated number N of windings, and this operation is repeated. The pitch amount is sent from the sequencer 24 to the bobbin feed controller 25 for control.
[0021]
Instead of the bobbin rotation amount detection encoder 10 and the bobbin horizontal movement amount detection encoder 20, sensors may be attached to the rotation shaft 36 and the bobbin feed ball screw 22 and counted in the sequencer 24. Further, the port end detection side length sensor 13 and the starboard end detection side length sensor 14 may be one of a proximity type, a reflection type, a distance sensor, and a transmission type. Further, the port end detection side length sensor 13 and the starboard end detection side length sensor 14 may be arranged outside the rod 4 to measure the inner width of the bobbin 2.
[0022]
