Description

  The present invention relates to a technique for adjusting a traverse reversal position when winding a wire around a bobbin.

Conventionally, there are a traverse method in which a traverser for guiding a wire rod to a bobbin is reciprocated left and right and a bobbin traverse method in which a bobbin is reciprocated left and right.
In order to allow the bobbin to wind up the wire with high accuracy, various measures have been taken against changes in the flange width of the bobbin and mounting errors of the bobbin on the winding shaft.

  In the technique disclosed in Patent Document 1, an optical sensor is mounted on a sensor block that is driven left and right by a screw shaft parallel to the bobbin shaft, the screw shaft is driven by a pulse motor, and the optical sensor is wound on a wire. It is arranged on the extended line of the path, and when the optical sensor detects the position of the edge of the bobbin flange, the bobbin traverse drive motor is reversed by the traverse control device.

In the configuration disclosed in Patent Document 1 described above, the position of the bobbin is detected by the optical sensor, and thereby the reversal of the traverse is controlled. The wire can be wound up to.
However, the edge of the bobbin flange is usually chamfered in order to prevent the end of the bobbin from being damaged or broken due to the wire being caught. For this reason, it is difficult to accurately detect the bobbin end by the optical sensor, and the reversal of the traverse cannot be accurately controlled, so that the winding of the wire is not uniform (the winding amount of the wire varies depending on the position of the bobbin and is uniform). It was disadvantageous in that it was not. In other words, since the optical sensor detects the bobbin end at a position past the chamfered portion, both ends of the bobbin are excessively wound, and when the flange end surface is detected and reversed, overwinding occurs due to the reverse delay. was there.

  Furthermore, if the bobbin end is essentially detected and then reversed, an inversion delay has already occurred, and the control delay of the inversion driving device itself also overlaps, so that the winding cannot be performed with high accuracy. Since this inversion delay is also affected by the traverse speed, it is impossible to eliminate the inversion apparatus by directly detecting the bobbin end by the sensor signal of the above-described optical sensor or the like.

  Further, in the traverse operation of the traverse type device, since the bobbin is wound and rotated while the traverser moves in the direction of the bobbin's rotation axis, the wire winding tension and the traverse speed in the direction of the rotation axis are affected. This traverse speed may require changing the traverse speed relative to the speed of the rotating shaft of the bobbin, that is, adjusting the traverse pitch. Therefore, even if the bobbin end can be accurately detected, it is not easy to make the best timing for traverse inversion.

  As described above, since the detection operation is delayed in the reversing operation after the bobbin end is detected, fine adjustment corresponding to the traverse speed is required.

  A contrivance regarding the inversion operation delay after the bobbin end detection is disclosed in Patent Document 2.

  The technique disclosed in Patent Document 2 is a traverse method in which a linear body supplied via a traverse roller is wound around a reel, and two sets of photoelectric switches are provided on both sides of the traverse roller. Light between the photoelectric switches of either of the two sets is arranged in a direction that crosses the reel axis of the reel and is opposed to the rotation axis of the reel, and is moved relative to the reel and the traverse roller. It is characterized in that a signal indicating that the shaft has been blocked by the reel of the reel is detected as a signal, and this detection signal is delayed by a predetermined time by a timer to reverse traverse.

This is to set a time delay from the detection of the optical axis between the photoelectric switches being interrupted by the reel of the reel to the reverse of the traverse by a timer. min), when trying to control the time for a wire having a wire diameter of 20 μm, etc., it is necessary to make an adjustment with an accuracy of about 0.01 seconds or more. It becomes necessary and depends on the linear velocity, and the usable range is limited.

  Next, embodiments of the invention will be described.

  Below, Example 1 of one form of implementation of the wire rod winding device concerning the present invention is described.

  As shown in FIG. 1, the wire winding device 100 is a device for causing a bobbin 110 to wind a wire 120 such as a metal wire or an optical fiber. The wire winding device 100 mainly includes a traverse device 130, a bobbin end detection device 140, a traverse position detection device 150, and a bobbin driving unit 113.

  Among the wires 120, a wire rod (wire rod wound around the bobbin 110 from the traverse portion 131) located between the traverse portion 131 and the bobbin 110 is defined as a wire rod 120a. Further, a flange on one side (right side) of the bobbin 110 is a first bobbin end 111 and a flange on the other side (left side) is a second bobbin end 112.

The traverse device 130 is a device that guides the wire 120 a to be wound around the bobbin 110.
The traverse device 130 mainly includes a traverse shaft 133, a traverse unit 131, and a traverse control unit 132.

  The traverse shaft 133 is disposed in parallel with the rotation shaft 101 of the bobbin 110 and guides the traverse portion 131 so as to reciprocate along the traverse shaft 133.

The traverse unit 131 guides the wire 120a to set the introduction position to the bobbin 110, a dancer that automatically adjusts the wire conveyance amount, and forward / reversely rotates the traverse unit 131 to rotate the shaft 101 of the bobbin 120. A servo motor 131a that reciprocates in the direction is provided.
Thus, the traverse part 131 reciprocates in the direction of the rotation axis 101 of the bobbin 110 to guide the wire 120a to the bobbin 110.

  The traverse control unit 132 controls a series of operations related to forward rotation, reverse rotation, and the like of the servo motor 131a.

The traverse control unit 132 may actually be configured such that a CPU, ROM, RAM, HDD, or the like is connected by a bus, or may be configured by a one-chip LSI or the like.
The traverse control unit 132 stores a control program and the like, expands the control program and transmits information related to normal rotation, reverse rotation, and the like to the servo motor 131a, thereby controlling the reciprocating motion of the traverse unit 131.

The bobbin driving unit 113 includes a servo motor 113a for rotating the bobbin 110 forward and backward, and a bobbin control unit 113b for controlling a series of operations such as normal rotation and reverse rotation of the servo motor.
The bobbin driving unit 113 rotates the bobbin 110 in order to wind the wire 120 a guided from the traverse unit 131 around the bobbin 110.

The bobbin end detection device 140 touches the first bobbin end 111 or the second bobbin end 112 by detecting the tension in the direction of the rotation axis 101 of the bobbin of the wire 120a wound around the bobbin 110 from the traverse part 131. It is a device that detects this.
As shown in FIGS. 2 and 3, the bobbin end detection device 140 mainly includes a strain gauge type load cell 141, a first protrusion 142 and a second protrusion 143 serving as a detection piece, and a control unit 144.
As shown in FIG. 1, the load cell 141 is attached to the traverse unit 131.

  As shown in FIG. 3, the first protrusion 142 and the second protrusion 143 are attached to the load cell 141 via attachment members. The first protrusion 142 and the second protrusion 143 are arranged in parallel with a predetermined interval W therebetween. The first protrusion 142 and the second protrusion 143 may be rod-shaped members (for example, injection needles).

  The wire 120a is configured to pass the interval W while being guided from the traverse part 131 to the bobbin 110.

  The control unit 144 detects that the wire 120a has touched the first bobbin end 111 or the second bobbin end 112.

  The control unit 144 may actually have a configuration in which a CPU, a ROM, a RAM, an HDD, and the like are connected by a bus, or may be configured by a one-chip LSI or the like.

  The control unit 144 stores a control program, which will be described later, and develops the control program to detect that the wire 120a has touched the first bobbin end 111 or the second bobbin end 112.

  The load cell 141 is connected to the control unit 144, and information related to the tension of the wire 120 a detected by the load cell 141 is transmitted to the control unit 144.

As shown in FIGS. 2 and 3, when the load cell 141 (traverse portion 131) moves toward the first bobbin end 111, the wire rod 120 a touches the first bobbin end 111. Thereby, the inclination of the conveyance direction of the wire 120a changes. At the same time, the tension in the direction of the rotation axis 101 of the bobbin 110 of the wire 120a changes. Then, the wire 120a touches the second protrusion 143.
When the wire 120 a touches the second protrusion 143, the tension F in the direction of the rotation axis 101 of the bobbin 110 of the wire 120 a is transmitted to the load cell 141 via the second protrusion 143. Then, information related to the tension F is obtained as a detection value of the load cell 141. Thus, the tension F in the direction of the rotation axis 101 of the bobbin 110 of the wire 120a is indirectly detected by the load cell 141 by being transmitted to the load cell 141 through the second protrusion 143.
The control unit 144 detects that the wire 120 a has touched the first bobbin end 111 by receiving information on the tension F from the load cell 141.

When the load cell 141 (traverse portion 131) moves toward the second bobbin end 112, the wire 120a touches the second bobbin end 112. When the wire 120 a touches the first protrusion 142, the tension in the direction of the rotation axis 101 of the bobbin 110 is indirectly detected by being transmitted to the load cell 141 via the first protrusion 142.
The control unit 144 detects that the wire 120 a has touched the second bobbin end 112 by receiving information on the tension from the load cell 141.

  As described above, the bobbin end detection device 140 detects the tension in the direction of the rotation axis 101 of the bobbin 110 of the wire 120a, so that the wire 120a touches the first bobbin end 111 or the second bobbin end 112 (traverse portion). 131) is detected.

  As the interval W is increased, the time from when the wire 120a touches the first bobbin end 111 to the second protrusion 143 and the time from the second bobbin end 112 to the first protrusion 142 are touched. , The accuracy of the bobbin end detection device 140 is sacrificed.

  When the interval W is reduced, the wire 120a is not in contact with the first bobbin end 111 or the second bobbin end 112 in a state where the wire 120 is being transported to the bobbin 110 by the traverse device 130 (transport state). Since the first protrusion 142 or the second protrusion 143 may be touched, the controller 144 may detect that the wire 120a has touched the first bobbin end 111 or the second bobbin end 112 even in such a case. There is.

  Therefore, the interval W is not too wide, and when the wire 120a is not touching the first bobbin end 111 or the second bobbin end 112 in the transport state, the wire 120a is not in contact with the first protrusion 142 or the second protrusion 143. The spacing is such that it is not touched (preferably within a range of 1.1 to 2 times the diameter of the wire). For example, the interval W is determined in consideration of the type of the wire 120, the distance between the traverse part 131 and the bobbin 110, the moving speed of the traverse part 131, the vibration of the winding machine itself, and the like.

In addition, the distance between the first protrusion 142 and the second protrusion 143 is made narrower than the distance W of the present embodiment, and the wire 120a is moved to the first bobbin end 111 or the second bobbin end 112 in the transport state. Even when not touching, the first protrusion 142 or the second protrusion 143 may be touched.
According to the above configuration, even when the wire 120a does not touch the first bobbin end 111 or the second bobbin end 112, the load cell 141 detects the tension of the wire 120a by touching the first protrusion 142 or the second protrusion 143. There is a case.
In this case, the control unit 144 determines whether or not the wire 120a has touched the first bobbin end 111 or the second bobbin end 112 depending on whether or not the tension of the wire 120a detected by the load cell 141 is greater than a predetermined value. Do. The predetermined value is detected by the load cell 141 by touching the first protrusion 142 or the second protrusion 143 when the wire 120a does not touch the first bobbin end 111 or the second bobbin end 112 in the transport state. This means the tension.

In the present embodiment, the wire 120a is detected by using the load cell 141, the first protrusion 142, and the second protrusion 143 to detect the tension in the direction of the rotation axis 101 of the bobbin 110 of the wire 120a. Alternatively, the touch of the second bobbin end 112 is detected. However, instead of the above-described configuration, for example, the inclination of the conveyance direction of the wire 120a is detected using an optical sensor, or the wire 120a is detected using an electrostatic sensor. It is good also as a structure which detects that the wire 120a touched the 1st bobbin end 111 or the 2nd bobbin end 112 by detecting this position.
Specifically, since the inclination of the conveyance direction of the wire 120a changes when the wire 120a touches the first bobbin end 111 or the second bobbin end 112, an optical sensor is provided in the traverse part 131 to change the inclination of the conveyance direction. The optical sensor is configured to react to the finished wire 120a.

  The traverse position detection device 150 detects the position of the traverse unit 131.

  As shown in FIG. 1, the traverse position detection device 150 mainly includes a first potentiometer 151 and a second potentiometer 152 as linear position detection means.

  The first potentiometer 151 and the second potentiometer 152 are provided on both ends of the bobbin 110 in the direction of the rotation axis 101. These may correspond to minute error displacements such as a manufacturing error of the bobbin itself or a displacement due to variations in the bobbin mounting to the winding device, and a highly accurate but small size can be used. The first potentiometer 151 and the second potentiometer 152 may be analog potentiometers or digital potentiometers.

  Next, the first potentiometer 151 and the second potentiometer 152 will be described as a linear sliding potentiometer.

  The first potentiometer 151 is moved while sliding on the variable resistor 151a, the wiper 151b that divides and outputs the input voltage to the variable resistor 151a according to the contact position, the shaft 151c having the wiper 151b, and the like. It comprises.

  As the traverse portion 131 moves toward the first potentiometer 151, the traverse portion 131 comes into contact with the shaft 151c. Further, when the traverse part 131 moves to the first potentiometer 151 side, the traverse part 131 and the shaft 151c (wiper 151b) move integrally. Information regarding the position of the traverse unit 131 is obtained as a detection value of the first potentiometer 151.

The second potentiometer 152 includes a variable resistor 152a, a wiper 152b, a shaft 152c, and the like.
As the traverse portion 131 moves toward the second potentiometer 152, the traverse portion 131 contacts the shaft 152c. Further, when the traverse part 131 moves to the second potentiometer 152 side, the traverse part 131 and the shaft 152c (wiper 152b) move integrally. Information regarding the position of the traverse unit 131 is obtained as a detection value of the second potentiometer 152.

  In this way, the traverse position detection device 150 detects the position of the traverse unit 131.

  The inversion position calculation device 160 includes information related to contact between the wire 120 a detected by the bobbin end detection device 140 and the first bobbin end 111 or the second bobbin end 112 of the bobbin 110 and the traverse detected by the traverse position detection device 150. This is a device that calculates the reverse position, which is the position of the traverse part 131 when the wire 120a touches the first bobbin end 111 or the second bobbin end 112, based on information relating to the position of the part 131.

The inversion position calculation device 160 may actually have a configuration in which a CPU, a ROM, a RAM, an HDD, and the like are connected by a bus, or may be configured by a one-chip LSI or the like.
The inversion position calculation device 160 stores a calculation program or the like to be described later, expands the calculation program or the like, and is the position of the traverse portion 131 when the wire 120a touches the first bobbin end 111 or the second bobbin end 112. Calculate the reversal position.

  The control unit 144 is connected to the reverse position calculation device 160, and information about the contact of the wire 120 a with the first bobbin end 111 or the second bobbin end 112 detected by the control unit 144 is the reverse position calculation device. 160.

  The first potentiometer 151 and the second potentiometer 152 are connected to the reverse position calculation device 160, and information related to the position of the traverse unit 131 detected by the first potentiometer 151 and the second potentiometer 152 is transmitted to the reverse position calculation device 160. Is done.

  When the reversal position calculation device 160 receives information from the control unit 144 that the wire 120a has detected that the first bobbin end 111 or the second bobbin end 112 has been touched, the reversal position calculation device 160 receives from the first potentiometer 151 or the second potentiometer 152. The received position of the traverse unit 131 at this time is calculated as an inversion position.

  As described above, the inversion position calculation device 160 uses the information related to the contact between the wire 120 a detected by the bobbin end detection device 140 and the first bobbin end 111 or the second bobbin end 112 of the bobbin 110 and the traverse position detection device 150. Based on the detected information relating to the position of the traverse part 131, a reverse position, which is the position of the traverse part 131 when the wire 120a touches the first bobbin end 111 or the second bobbin end 112, is calculated.

  Below, Example 2 of one form of implementation of the wire rod winding device concerning the present invention is described.

The wire rod winding device 200 shown in the second embodiment is obtained by adding / deleting some devices to the wire rod winding device 100 shown in the first embodiment.
Below, a change with the wire winding apparatus 100 shown in Example 1 is demonstrated.

As shown in FIG. 4, the traverse device 230 includes a traverse control unit 232.
The traverse control unit 232 may actually have a configuration in which a CPU, a ROM, a RAM, an HDD, and the like are connected by a bus, or may be configured by a one-chip LSI or the like.
The traverse control unit 232 stores a control program, which will be described later, expands this control program, and transmits information related to forward rotation, reverse rotation, etc. to the servo motor 131a, thereby controlling the reciprocating motion of the traverse unit 131.

  The first potentiometer 151 and the second potentiometer 152 are connected to the traverse control unit 232, and information related to the position of the traverse unit 131 detected by the first potentiometer 151 and the second potentiometer 152 is transmitted to the traverse control unit 232. Is done.

  The reverse position calculation device 160 is connected to the traverse control unit 232, and information related to the reverse position calculated by the reverse position calculation device 160 is transmitted to the traverse control unit 232.

When the operator operates the traverse device 230, the traverse unit 131 starts reciprocating motion. When the traverse part 131 moves toward the first bobbin end 111 side, the wire 120a touches the first bobbin end 111.
When the inversion position calculation device 160 receives information related to detecting that the wire 120a has touched the first bobbin end 111 from the bobbin end detection device 140 (specifically, the control unit 144), the reverse position calculation device 160 receives the information from the first potentiometer 151. The received position of the traverse unit 131 at this time is calculated as an inversion position.
Then, the traverse control unit 232 receives information about the reverse position calculated by the reverse position calculation device 160 from the reverse position calculation device 160.
Then, the traverse control unit 232 sets the corrected reverse position of the traverse unit 131 based on the reverse position calculated by the reverse position calculation device 160. That is, the traverse control unit 232 sets a corrected reverse position that is the same as or different from the reverse position, with the reverse position calculated by the reverse position calculation device 160 as a reference. For example, the traverse control unit 232 uses the reverse position as a reference, the moving speed of the traverse unit 131, the time lag at the time of reverse, the responsiveness of the traverse device 130, the type of the wire 120, the rotational speed of the bobbin 110, The correction reversal position is set in consideration of the thickening of the winding, the degree of insufficient winding, etc. occurring at both ends 111 and 112 of the bobbin 110 when the traverse portion 131 is reversed at the reversing position. Specifically, when the traverse unit 131 is reversed at the reversal position and the windings are generated at both ends 111 and 112 of the bobbin 110, the traverse control unit 232 considers the moving speed of the traverse unit 131 described above. Thus, the corrected reverse position is set at a position closer to the center of the bobbin 110 in the direction of the rotation axis 101 than when the traverse unit 131 is at the reverse position calculated by the reverse position calculating device 160.

  In the subsequent reciprocation of the traverse unit 131, the traverse control unit 232 compares the corrected reverse position set by the traverse control unit 232 with the position of the traverse unit 131 detected by the first potentiometer 151, and When the position of the part 131 reaches the correction reversal position, information related to reversing the rotation direction is transmitted to the servo motor 131a. As a result, the traverse direction of the traverse unit 131 is reversed.

When the wire rod 120 a moves to the second bobbin end 112 side and touches the second bobbin end 112, the traverse control unit 232 displays information related to the reversal position calculated by the reversal position calculation device 160. Receive from. Then, the traverse control unit 232 sets the corrected reverse position of the traverse unit 131 based on the reverse position.
In the subsequent reciprocation of the traverse unit 131, the traverse control unit 232 performs reversal of the traverse unit 131 when the position of the traverse unit 131 detected by the second potentiometer 152 reaches the corrected reversal position.

  As described above, the traverse control unit 232 sets a corrected reversal position that is the same as or different from the reversal position based on the reversal position calculated by the reversal position calculation device 160, and is detected by the traverse position detection device 150. When the position of the part 131 reaches the corrected reversal position, the traverse part 131 is reversed. That is, the traverse control unit 232 reverses the traverse unit 131 based on the reverse position calculated by the reverse position calculation device 160.

With this configuration, when the traverse unit 131 is reversed at the reversal position calculated by the reversal position calculation device 160, the first bobbin end 111 and / or the second bobbin end 112 (bobbin end) is wound with Even if winding shortage may occur, the traverse control unit 232 may reduce the moving thickness of the traverse unit 131, the time lag during reversal, the responsiveness of the traverse device 130, In consideration of the type of the wire 120, the rotation speed of the bobbin 110, the degree of winding thickness or insufficient winding, etc., a correction reversal position is set based on the reversal position, and the traverse part 131 is reversed at the correction reversal position. Can be made.

  In addition, you may use what integrated the function as the display apparatus 370, and the function as the input device 380, such as a commercially available touch panel.

The storage device 390 stores the reverse position calculated by the reverse position calculation device 160 and the corrected reverse position input by the input device 380.
The storage device 390 is essentially a storage medium such as an HDD (hard disk drive), a CD-ROM, a DVD-ROM or the like.

When the operator operates the traverse device 330, the traverse unit 131 starts reciprocating motion. When the traverse part 131 moves toward the first bobbin end 111 side, the wire 120a touches the first bobbin end 111.
When the inversion position calculation device 160 receives information related to detecting that the wire 120a has touched the first bobbin end 111 from the bobbin end detection device 140 (specifically, the control unit 144), the reverse position calculation device 160 receives the information from the first potentiometer 151. The received position of the traverse unit 131 at this time is calculated as an inversion position.
The display device 370 receives information related to the inversion position calculated by the inversion position calculation device 160 from the inversion position calculation device 160 and displays the information.

With this configuration, when the traverse unit 131 is reversed at the reversal position calculated by the reversal position calculation device 160, the first bobbin end 111 and the second bobbin end 112 may be thickened or insufficiently wound. Even in such a case, the operator or the like can reduce the moving thickness of the traverse unit 131, the time lag at the time of reversal, the responsiveness of the traverse device 130, the type of the wire 120, the bobbin, etc. In consideration of the rotation speed of 110, the degree of winding thickness, insufficient winding, and the like, a correction reversal position can be set based on the reversal position, and the traverse unit 131 can be reversed at the correction reversal position.
As a result, the wire 120 can be wound around the bobbin 110 uniformly and accurately.

In addition, since the reverse position calculated by the reverse position calculation device 160 and the corrected reverse position input by the input device 380 are stored in the storage device 390, when the bobbin is replaced with the same type, the operator or the like There is no need to calculate the reversal position or set the correction reversal position again.
Thereby, the labor of the operator can be reduced.

  Note that a display device may be provided in which when the operator inputs a correction reversal position to the input device 380, information relating to the correction reversal position is displayed as a percentage (correction reversal position / reversal position × 100) in comparison with the reversal position. Good.

Based on the detected information related to the position of the bobbin 110, a reverse position, which is the position of the bobbin 110 when the wire 120a touches the first bobbin end 111 or the second bobbin end 112, is calculated.

  Below, Example 5 of one form of embodiment of the wire rod winding device concerning the present invention is described.

The wire rod winding device 500 shown in the fifth embodiment is obtained by adding or deleting some devices to the wire rod winding device 400 shown in the fourth embodiment.

  The inversion position calculation device 460 is connected to the bobbin control unit 515, and information related to the inversion position calculated by the inversion position calculation device 460 is transmitted to the bobbin control unit 515.

When the wire rod 120a touches the first bobbin end 111 due to the bobbin 110 moving to the second bobbin end side 112, the bobbin control unit 515 reverses the information related to the reverse position calculated by the reverse position calculation device 460. Received from the position calculation device 460.
Then, the bobbin control unit 515 sets a corrected reversal position of the bobbin 110 based on the reversal position. That is, the bobbin control unit 515 sets a corrected reversal position that is the same as or different from the reversal position on the basis of the reversal position calculated by the reversal position calculation device 460. For example, the bobbin controller 515 uses the reversing position as a reference, the moving speed of the bobbin 110, the time lag at the time of reversing, the responsiveness of the bobbin traverse device 513, the type of the wire 120, the rotational speed of the bobbin 110, The correction reversal position is set in consideration of the thickness of winding and the degree of insufficient winding occurring at both ends of the bobbin 110 when the bobbin 110 is reversed at the reversal position. Specifically, when the bobbin 110 is reversed at the reversal position and the bobbin 110 is thickened at both ends, the bobbin control unit 515 takes into account the moving speed of the bobbin 110 and the like. The wire guide device 430 sets the corrected reversal position at a position closer to the center of the bobbin 110 in the direction of the rotation axis 401 than when the bobbin 110 supported by 414 is at the reversal position calculated by the reversal position calculation device 460.

  In the subsequent reciprocation of the bobbin 110, the bobbin controller 515 performs the reversal of the bobbin 110 when the position of the bobbin 110 detected by the second potentiometer 452 reaches the corrected reversal position.

Received from the position calculation device 460.
Then, the bobbin control unit 515 sets a corrected reversal position of the bobbin 110 based on the reversal position.

  In the subsequent reciprocation of the bobbin 110, the bobbin control unit 515 performs reversal of the bobbin 110 when the position of the bobbin 110 detected by the first potentiometer 451 reaches the corrected reversal position.

  As described above, the bobbin control unit 515 sets a corrected reversal position that is the same as or different from the reversal position based on the reversal position calculated by the reversal position calculation device 460 and detects the bobbin detected by the bobbin position detection device 450. When the position 110 reaches the corrected reversal position, the bobbin 110 is reversed. That is, the bobbin control unit 515 performs reversal of the bobbin 110 based on the reversal position calculated by the reversal position calculation device 460.

With this configuration, when the bobbin 110 is reversed at the reversal position calculated by the reversal position calculation device 460, the first bobbin end 111 and the second bobbin end 112 may become thicker or insufficiently wound. Even so, the bobbin control unit 515 may reduce the above-described thickening and winding shortage, the moving speed of the bobbin 110, the time lag during reversal, the responsiveness of the bobbin traverse device 513, the type of the wire 120, the bobbin The correction reversal position can be set based on the reversal position in consideration of the rotation speed of 110, the degree of winding thickness or insufficient winding, and the bobbin 110 can be reversed at the correction reversal position.
As a result, the wire 120 can be wound around the bobbin 110 with high accuracy and uniformity.

  Note that, using a circuit composed of a comparison circuit, a relay, or the like, the corrected reversal position set by the bobbin control unit 515 in the circuit is compared with the position of the bobbin 110 detected by the bobbin position detection device 450, and When the position of the bobbin 110 exceeds the corrected reversal position, information related to reversing the rotation direction of the traverse motor 414a may be transmitted to the bobbin control unit 515.

In the present embodiment, the bobbin control unit 515, the control unit 144, and the reverse position calculation device 460 are configured separately, but are not limited to the above-described configuration, and may be configured integrally, for example.
Further, the bobbin control unit 515, the control unit 144, and the reverse position calculation device 460 are not limited to dedicated products, and can be achieved by storing the above-described program in a commercially available personal computer, workstation, or the like.

  Further, during the wire winding operation, in order to confirm whether or not the reversing position calculated by the reversing position calculating device 460 has a deviation, the reversing position is determined after a predetermined time has elapsed or the bobbin 110 has reciprocated a predetermined number of times. The calculation program of the inversion position calculation device 460 may be configured to calculate again.

Further, the operator or the like makes the selection switching device 870 in a state where the first input unit 871a and the output unit 871c are connected during the winding operation of the wire 120a at the bobbin correction reversal position. Can be calculated and displayed on the display device 862, so that it can be confirmed whether there is any deviation from the previously set bobbin reversal position.

  When the bobbin 110 is reversed at the bobbin reversal position, even if the first bobbin end 111 or the second bobbin end 112 may be thickened or insufficiently wound, the operator or the like may In order to reduce the shortage, the moving speed of the bobbin 110, the time lag at the time of reversal, the responsiveness of the bobbin control unit 815, the type of the wire 120, the rotational speed of the bobbin 110, the extent of the above-described thickening and insufficient winding The bobbin correction reversal position can be set based on the bobbin reversal position displayed on the display device 862, and the bobbin 110 can be reversed at the bobbin correction reversal position. This bobbin correction position change can be calculated as an integral multiple of the wire diameter in the case of aligned winding, and is clearly expressed as an integral multiple of the traverse pitch in the case of the ratio between the winding speed and the traverse speed, i.e. in the case of traverse pitch control. As a result, the wire 120 can be easily wound around the bobbin 110 with high accuracy and uniformity.

The reversal position calculated by the reversal position calculation device 860 is stored in the bobbin reversal timing position storage device 861, and the bobbin correction reversal position calculated by the correction reversal position calculation device 880 is stored in the correction reversal position storage device 881. Therefore, when the bobbin is replaced with the same type, the operator or the like does not need to calculate the reversal position or the corrected reversal position again.
Thereby, the labor of the operator can be reduced.

  Note that the bobbin bobbin reversal timing detection device 840 according to the present embodiment detects the magnitude of the tension of the wire 120a, the position of the wire 120a, and the conveyance of the wire 120a when the wire 120a touches the first bobbin end 111 or the second bobbin end 112. The timing when the bobbin 110 is reversed may be detected when it is detected that the inclination of the direction has changed. For example, when the change in the magnitude of the tension of the wire 120a is used as the reversal timing, the bobbin end detection device 440 of the fourth embodiment is used. When the change in the position of the wire 120a is used as the reversal timing, the position of the wire 120a is detected using an electrostatic sensor, and when the change in the inclination of the conveyance direction of the wire 120a is used as the reversal timing, the optical material is used. An apparatus configured to detect that the wire 120a touches the first bobbin end 111 or the second bobbin end 112 by detecting the inclination of the conveyance direction of 120a is used.

In order to wind the wire rod around the bobbin accurately and uniformly, if the bobbin position information such as the bobbin end is correct, based on the above information, taking into account the winding speed of the wire rod, the traverse speed, the reverse delay of the traverse drive device, etc. The corrected reverse position must be set appropriately. If the bobbin is not wound evenly and accurately after setting, it is necessary to further correct the reverse position. If this correction is performed accurately, the wire can be wound around the bobbin with high accuracy and uniformity.
Therefore, even if the bobbin is replaced, if the characteristics of the bobbin and the wire winding device do not change significantly, the correct correction data is reflected, so that the wire can be wound around the bobbin with high accuracy.
The inversion timing detection devices 740 and 840 of the present invention are not necessarily required to accurately detect the position of the bobbin, and it is sufficient that the relative position between the wire and the bobbin is clear. For example, it is possible to detect the bobbin directly with light, or to detect that the wire has touched the end of the bobbin by changing the tension.
