Description

[Detailed description of the invention] TECHNICAL FIELD The present invention relates to an aligned winding method for wire rods and an apparatus therefor.

In order to wind wire rods, especially thin wires with a diameter of around 1 leg, on a bobbin in an aligned manner, conventionally, a traverse shaft threaded at a predetermined pitch is provided parallel to the bobbin axis, and the feeding position of the winding wire rod is set on the traverse shaft. A traverse table equipped with a pair of guide rollers that engage the traverse shaft is screwed together, and by rotating the traverse shaft, the traverse table is caused to traverse at a pitch equal to the outer diameter of the winding wire village, thereby feeding the winding wire material. A limit switch is provided in the movement path of the traverse table corresponding to each bobbin flange position to regulate the position and engage with the traverse table to give a reverse command to the traverse table, and the winding direction is turned back at both bobbin flange positions. Generally, the method of winding the material is used. At this time, in order to eliminate gaps between the winding loops on the bobbin and maintain an aligned winding state, it is necessary to obtain an appropriate reversal timing of the traverse table at the edge of the bobbin. In this case, the winding position of the wire strip on the bobbin and the center position of the guide roller must match in the bobbin axial direction. However, there is some external flea error in the wound wire, and there is also a slight error in the moving pitch of the traverse table, and these errors accumulate as the number of turns of the wire increases. Eventually, a non-negligible deviation will occur between the winding position of the wire on the bobbin and the center position of the guide roller. For this reason, in the conventional method, it was not possible to obtain the optimal timing for reversing the traverse table during winding, and gaps were created between the winding loops, making it impossible to maintain a satisfactory aligned winding state. . This tendency becomes more noticeable as the number of windings of the wire village and the number of winding layers increases, and as the outer diameter of the wire becomes smaller, and it also becomes difficult to correct it. The present invention has been made to eliminate the above-mentioned conventional drawbacks, and includes:
To provide a wire rod aligned winding method and device that can always obtain a proper reversal timing of a traverse table at the edge of a bobbin regardless of an increase in the number of windings and the number of winding layers, and can therefore always maintain closely aligned aligned winding. The purpose is to provide.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in the drawings, an apparatus for carrying out the aligned winding method of the present invention includes a winding bobbin that is rotated around the koji core by a drive source (not shown). 2, and a traverse shaft 4 arranged parallel to the bobbin shaft and threaded at a predetermined pitch.
, a guide rod 6 arranged parallel to the traverse shaft, a traverse table 8 screwed and slidably engaged with the traverse shaft and the guide rod, respectively, and a traverse table 8 provided on the traverse table and wound on a bobbin. A pair of left and right guide rollers 12 that engage and guide the wire village 10 toward the bobbin, and a pair of guide rollers 12 protruding from one side of the traverse table so as to coincide with the center line of the guide rollers, that is, the center line A of the feeding wire material. terminal 14,
A counter 16 provided on the traverse shaft to measure the amount of movement of the traverse table, and a pair of left and right contacts 18 arranged so as to be able to engage with the terminals 14 corresponding to the positions of the left and right bobbin collars.
, 18', control means 20, 20' that can move the corresponding contact point from the bobbin collar position in the direction of the bobbin axis and return it based on a command from the counter 16, and a control means 20, 20' that can rotate the bobbin axis provided on the bobbin axis. It consists of a counter 22 for counting numbers.

The traverse shaft 4 is rotated in forward and reverse directions around its bag center by a drive source (not shown), thereby causing the traverse table 8 to traverse left and right at a speed that matches the winding pitch on the bobbin.

Further, the counter 16 provided on the traverse shaft is
It is possible to set the amount of movement of the traverse table from one bobbin collar 2a when the wire rod is wound in a predetermined number of turns from one bobbin collar 2a in advance, and also to set the amount of movement of the traverse table from one bobbin collar 2a when the wire rod is wound in a predetermined number of turns from the one bobbin collar 2a. The amount of movement of the traverse table from one bobbin collar when the wire rod is wound a predetermined number of times is measured by measuring the rotation of the traverse shaft using pulses, and the distance from one bobbin collar 2a to the other bobbin collar is measured by measuring the rotation of the traverse shaft using pulses. 2
Each time winding is performed toward direction b, the measured amount is compared with a set amount to detect the difference, and the detected signal is introduced to the control device 20' on the other bobbin collar side. There is. The control device 20' is connected to a motor 24' connected to the motor 24' to move the corresponding contact 18' in the bobbin axis direction in response to a detection signal from the counter 16, and a contact point 18' in accordance with the magnitude of the detection signal from the counter 16. and measuring means 26' for determining the amount of movement of. When the contact 18' engages with the terminal 14 of the traverse table, it causes the corresponding motor 24' and measuring means 26' to actuate to stop the movement of the traverse table and simultaneously return the contact to the corresponding bobbin collar position. Give instructions. The measuring means gives a reverse operation command to the traverse table to move toward one bobbin collar after the contact returns. Further, when the contact 18 engages with the terminal 14 of the traverse table, it stops the movement of the traverse table, and at the same time causes the counter 22 to measure a predetermined rotation of the bobbin (until forming one turn of the next layer). 22 to give a reverse operation command to the traverse table. However, as will be described later, when the turning point of the traverse table is corrected for each winding layer, the contact 18 is connected to the motor 24 and the measuring means 26 in the same manner as the contact 18' in order to perform the same function as the contact 18'. can be provided.
Further, the counter 22 provided on the bobbin shaft is configured to simultaneously start the traverse table when forming the first winding layer.
When forming the second and subsequent layers, the rotation speed of the bobbin shaft is taught at the same time as the traverse table is reversed near one bobbin collar 2a, and when the predetermined rotation speed is measured, an operation command is sent to the counter 16 on the traverse shaft. The set amount is compared with the measured amount using the counter 6. Note that the counter 16 on the traverse shaft measures the number of revolutions of the traverse shaft at the same time as the start of the traverse table and the start of the reverse operation near one bobbin collar 2a. Now, in order to wind the wire in the above configuration, first, before starting winding, each contact point 18, 18' is aligned with the corresponding bobbin collar position, and the counter 22 is set at a predetermined winding rotation speed. is set, and the amount of movement of the traverse table from one bobbin collar 2a when the wire is wound in an aligned manner from one bobbin collar 2a by the predetermined number of turns is set in the counter 6.

This traverse table movement amount can be set, for example, by selecting the position of the traverse table corresponding to a predetermined number of aligned windings at a position (A in the illustrated example) where the feeding wire and the bobbin axis are perpendicular to each other as shown in the figure. Using this position as a reference point, the traverse table is moved in the winding start direction (C in the illustrated example), and the rotation of the traverse shaft at this time is read as the number of pulses by the counter 16, and the terminal 14 and the contact 18 are engaged. This can be done by setting the number of pulses at a time. Next, the bobbin shaft is rotated, and the traverse table is moved transversely at a predetermined pitch, that is, at a pitch corresponding to the outer diameter of the wire, and the wire is wound in the direction of the illustrated arrow. At this time, counter 2
2 counts the number of rotations of the bobbin, and counter 6 counts the rotation of the traverse shaft as pulses. When the bobbin is wound in this manner until it reaches the vicinity of the other bobbin collar and the bobbin is rotated a predetermined number of revolutions, the counter 22 issues a signal, and the counter 16 is activated based on the signal. That is, the counter 16 compares the number of pulses of the traverse shaft rotation at that time with a preset number of pulses. At this time, if the measured number of pulses and the set number of pulses match, it means that the guide roller center position A and the winding position B on the bobbin are aligned in the bobbin axial direction, and the traverse table continues to traverse. When the terminal 14 and the contact point 18' are engaged, the traverse is temporarily stopped, and the counter 22 measures a predetermined rotation angle of the bobbin (until the next layer is formed), and then the bobbin is directed toward one bobbin collar. be reversed. However, if the measured pulse number of the counter 16 and the set pulse number do not match, the counter 6 detects the difference between them and sends the detection signal to the control device 20'.

The control device moves the contact point 18' in the bobbin axial direction based on the detected amount. That is, in this case, since the center A of the guide roller 12 and the winding position B on the bobbin do not coincide,
When the winding position on the bobbin reaches the bobbin collar 2b, the contact point 18' is moved to a position where the terminal 14 of the traverse stand engages with the contact point 18'. Of course, during this time, the bobbin continues to rotate and the traverse table continues to move. In this way, when the contact 18' and the terminal 14 are engaged, the traverse table is temporarily stopped from moving, and at the same time, the contact 18' is moved by the motor 24' to return to the corresponding bobbin collar position. It will be done. When the sun point 18' is returned to the corresponding bobbin flange position, the measuring means 2
6' gives a reverse operation command to the traverse table.
The return speed of the contact 18' is determined by the time when the above contact 18' reaches the corresponding bobbin flange after the traverse table stops until the wire winding position on the bobbin turns around at the bobbin flange and returns to the center position of the guide roller again. The speed should be such that it returns to the position. Therefore, the traverse table is reversed when the guide roll center position and the wire winding position on the bobbin coincide in the bobbin axial direction. When the traverse table is reversed from the other bobbin collar 2b to the one bobbin collar 2a in this way, the measured values of the counters 16 and 22 are returned to zero, and the traverse table reaches the one bobbin collar 2a. When the terminal 14 and the contact point 18 engage, the traverse table is temporarily stopped, and after a predetermined rotation of the bobbin (until the next layer is formed) is measured by the counter 22, a reverse operation command is given by the counter, When forming the third winding layer, the same correction operation as the traverse table turning point correction operation for the first layer is performed again. In this way, by correcting the turn-back point of the traverse table every time winding is performed from one bobbin collar to the other bobbin collar, the optimum reversal timing of the traverse table at the edge of the other bobbin collar can be obtained, and the final The aligned winding state can be maintained until the winding layer is reached. In addition, in order to perform a correction operation at the time of turning back the traverse table for each winding layer, when forming an odd number of layers, that is, when winding is performed from one bobbin collar to the other bobbin collar, the line village winding on the bobbin must be When the position reaches the other bobbin collar 2b, that is, when the contact 18' and the terminal 14 engage, the measured values of the counters 6 and 22 are returned to zero, and the time when the traverse table is turned back is corrected when forming an odd number of layers. If there is no movement, the counter 16 starts measuring the amount of movement of the traverse table again at the same time as the traverse table is turned back, and the counter 22 measures the rotation of the bobbin after the traverse table has stopped about one rotation.

The counter 22 gives a reverse operation command to the traverse table when approximately one revolution has been measured after the start of measurement. If there is a correction operation at the time of turning back the traverse table when forming the odd-numbered layer, after the measured values of both counters 16 and 22 are returned to zero, the counters 6 and 22 change the set value by the correction amount. The counter 16 starts measuring again at the same time as the traverse table turns, and the counter 2
2 measures the number of revolutions of the bobbin at the same time as the traverse table is turned back. As described above, according to the present invention, the final reversal timing of the traverse table can always be obtained regardless of the error in the outer diameter of the wire and the error in the traverse pitch, so that the aligned state can be maintained until the final winding layer.
