  However, the above winding machine has the following problems. That is, this type of conventional winding machine including the winding machine described above is configured on the premise that only one wire is wound around a winding target. On the other hand, in a magnetic sensor, a current sensor, or the like, two coils may be provided in one core. When manufacturing such a sensor, it is necessary to wind two wires around one core. In this case, in order not to deteriorate the characteristics of the sensor, it is necessary to uniformly wrap two wires around the core at equal intervals so as not to cause twisting and overlapping. However, since the conventional winding machine has only a function of winding one wire, if the flyer is rotated while pulling out the two wires from the nozzle, the two wires are wound around the core while being twisted. Therefore, it is difficult to perform uniform winding at equal intervals. As described above, the conventional winding machine has a problem that it is difficult to wind a plurality of wire rods around a winding target in an orderly manner (uniformly at equal intervals).

By arranging the wire rod, the wire rod can be smoothly guided to the winding portion without providing a guide portion for guiding each wire rod fed out from each bobbin held by the holding portion to the winding portion. . Therefore, according to this winding machine, the configuration of the winding machine 1 can be sufficiently simplified because such a guide portion is unnecessary.

  In addition, according to the winding machine of the fourth aspect, the wire rod is loosened due to excessive rotation of the bobbin by providing the rotation restricting portion that restricts the rotation of the bobbin when the wire is fed by applying a load to the bobbin.

As shown in FIG. 2, two extraction holes 33 are formed in the central portion of the arm 31 a to draw out the wire 200 through which the insertion hole of the rotating shaft 32 is inserted. Furthermore, a weight 34 for balance adjustment is disposed at one end of the arm 31a.

  The arm 31b corresponds to a supply unit, and as shown in FIGS. 1 to 3, is attached to the arm 31a so as to protrude in the horizontal direction from the other end of the arm 31a. Further, the arm 31b can be inserted with the wire 200 and communicates from the base end portion (end portion on the back side of the paper surface in FIG. 2) to the tip end portion (end portion on the front side of the paper surface in FIG. 2). 35 is formed. In this case, as shown in the figure, the wire 200 drawn out from the drawing hole 33 of the arm 31a is inserted into the insertion hole 35 from the opening 36 on the proximal end side in the insertion hole 35 and passes through the insertion hole 35. It is inserted and pulled out from the opening 37 on the distal end side in the insertion hole 35.

  The winding portion 3 supports the distal end portion of the arm 31b (on the distal end side in the insertion hole 35) while supporting the wire rod 200 fed from the bobbin 10 (see FIGS. 1 to 3) around which the wire rod 200 is wound by the arm 31b. The arm 31a is supplied from the opening 37) and rotated about the central axis X1 as described above, so that the arm 31b circulates around the core 100 supported by the support 6 and thereby the wire 200 is It is configured to wrap around the core 100.

  The holding part 4 is configured to be able to hold the bobbin 10 around which the flange 10b is formed at both ends of the cylindrical part 10a and the wire rod 200 is wound in a rotatable state. Specifically, as shown in FIGS. 1 to 3, the holding unit 4 includes a bottom plate 41 and a back plate 42 disposed so as to be perpendicular to the bottom plate 41. The bottom plate 41 is provided with two holding shafts 43 that are inserted into the cylindrical portions 10a of the bobbins 10 and hold the bobbins 10 in a rotatable state. As shown in FIG. 3, a rotating shaft 44 is attached to the center portion of the back plate 42. The rotating shaft 44 is supported by a bearing (not shown) attached to the pedestal 21b of the table 2b, whereby the holding unit 4 corresponds to the central axis X2 (corresponding to the second axis: It is possible to rotate around (see the figure). Further, the holding portion 4 is arranged such that the central axis X1 of the rotary shaft 32 attached to the arm 31a of the winding portion 3 and the central axis X2 of the rotary shaft 44 are coaxial (an example of parallelism). It is prescribed.

  The motor 5a is a servo motor that operates in accordance with the control of a control unit (not shown), and is attached to a base 21a of the table 2a as shown in FIGS. A pulley 51b is attached to the drive shaft 51a (see FIG. 3) of the motor 5a. Further, a belt 51c is stretched between the pulley 51b and a pulley 32a attached to the rotating shaft 32 of the arm 31a of the winding portion 3, and the rotational force of the motor 5a is transmitted through the belt 51c. This is transmitted to the rotating shaft 32, whereby the winding part 3 (arm 31a) is rotated.

  The motor 5b is a servo motor that operates according to the control of a control unit (not shown) (the control unit that controls the motor 5a), and is attached to a pedestal 21b of the table 2b as shown in FIGS. Yes. Further, the drive shaft 52a (see FIG. 3) of the motor 5b is connected to the rotating shaft 44 of the holding unit 4, whereby the rotational force of the motor 5b is transmitted to the rotating shaft 44, causing the holding unit 4 to rotate. It is done. In this case, the motors 5a and 5b respectively rotate the winding unit 3 and the holding unit 4 so that the rotation speed of the winding unit 3 and the rotation speed of the holding unit 4 become the same rotation speed according to the control of the control unit. .

  As shown in FIGS. 1 to 3, the support unit 6 includes a support column 61 and a clamping unit 62 disposed at the tip end portion (upper end portion in FIGS. 1 and 2) of the support column 61. The support portion 6 is configured to be able to support the core 100 by sandwiching and fixing one end portion of the core 100 by the sandwiching portion 62.

  The moving mechanism 7 maintains the state where the center of the virtual circle drawn by the rotation locus of the tip of the arm 31b is located on the axis of the core 100, while the winding position of the wire 200 in the core 100 (the wire 200 is The support portion 6 is moved (rotated) so that the winding position) moves along the length direction of the core 100 (an example of the winding direction of the wire 200).

  Specifically, as shown in FIGS. 1 and 2, the moving mechanism 7 includes a motor 71, one end of which is fixed to the drive shaft of the motor, and the other end is connected to the base end of the support 61 in the support 6. A fixed arm 72 is provided. In this case, the moving mechanism 7 operates while the motor 71 is operated in conjunction with the operation of the motors 5a and 5b according to the control of the control unit that controls the motors 5a and 5b. The core 100 is long by one pitch P of the winding (for example, a length corresponding to the sum of the diameters of the two wire members 200 wound around the core 100: see FIG. 4) while the winding portion 3 makes one rotation. The support part 6 (support 61) is rotated so as to move along the vertical direction.

  The rotation limiting unit 8 is a mechanism for preventing slack of the wire rod 200 by restricting excessive rotation (rotation due to inertia) of the bobbin 10 when the wire rod 200 is fed by applying a load to the bobbin 10. As shown in FIGS. 1 and 2, the holding plate 4 is attached to the bottom plate 41. The rotation restricting portion 8 presses the lower flange 10b of the bobbin 10 held by the holding portion 4 with the rod 81 biased upward, so that the friction force (load) of the bobbin 10 is increased. Limit excessive rotation.

  Next, a method for winding two wires 200 around the core 100 using the winding machine 1 will be described with reference to the accompanying drawings.

  First, the two bobbins 10 around which the wire 200 is wound are set (held) on the holding unit 4. Specifically, the cylindrical portion 10a of the bobbin 10 is inserted through the two holding shafts 43 disposed on the bottom plate 41 of the holding portion 4, and then a nut is screwed into the tip end portion of each holding shaft 43 to each bobbin. 10 is fixed. In this state, the tip of the rod 81 of the rotation restricting portion 8 presses the lower flange 10 b of the bobbin 10.

  Subsequently, the wire material 200 is supported on the arm 31 b of the winding unit 3. Specifically, the distal end portion of each wire 200 wound around each bobbin 10 is inserted through an insertion hole (not shown) in the rotating shaft 32 attached to the arm 31a of the winding portion 3, and the arm 31a. Are pulled out from the respective drawing holes 33 (see FIG. 2). Next, the leading end portion of each drawn wire 200 is inserted into the insertion hole 35 from the opening 36 on the proximal end side of the insertion hole 35 formed in the arm 31 b and is inserted through the insertion hole 35. Is pulled out from the opening 37 on the tip side.

  Next, the core 100 is supported by the support unit 6. Specifically, one end portion of the core 100 is sandwiched by the sandwiching portion 62 of the support portion 6 and the one end portion of the core 100 is fixed. Then, the front-end | tip part of each wire 200 is fixed to the one end part (winding start position) of the core 100 supported by the support part 6 using the fixing tool outside a figure.

  Then, the operating unit (not shown) is operated to start winding the winding machine 1. In response to this, the control unit operates the motors 5a and 5b to rotate the drive shafts 51a and 52a. At this time, along with the rotation of the drive shaft 51a, the belt 51c stretched between the pulley 51b attached to the drive shaft 51a and the pulley 32a attached to the rotation shaft 32 of the winding portion 3 is used. Thus, the rotational force of the motor 5a is transmitted to the rotating shaft 32 of the winding part 3, and the rotating shaft 32 is thereby rotated.

  Further, the rotation of the rotation shaft 32 causes the arm 31a of the winding portion 3 to rotate about the central axis X1 of the rotation shaft 32, and the arm 31b attached to the end of the arm 31a with the rotation of the arm 31a. , Orbiting around the core 100 supported by the support portion 6. At this time, the two wires 200 supplied while being supported by the arm 31b are wound around the core 100 as the arm 31b circulates (see FIG. 4).

  Further, along with the rotation of the drive shaft 52a of the motor 5b, the rotation shaft 44 connected to the drive shaft 52a rotates, and thereby the holding unit 4 rotates. In this case, the control unit controls the motors 5a and 5b so that the rotation speed of the winding unit 3 (arm 31a) and the rotation speed of the holding unit 4 are the same.

  The control unit controls the motor 71 of the moving mechanism 7 to operate the motor 71 in conjunction with the operation of the motors 5a and 5b. At this time, the arm 72 is rotated in accordance with the rotation of the drive shaft of the motor 71, and thereby, the support 61 of the support portion 6 is moved (rotated). Further, as the support 61 rotates, the core 100 fixed by the clamping unit 62 moves along the length direction.

  In this case, the control unit moves the core 100 along the length direction by one pitch P of the winding while the winding is performed once (each time the winding unit 3 makes one rotation). Thus, the motor 71 is controlled. For this reason, as shown in FIG. 4, each wire 200 is wound around the core 100 at equal intervals without overlapping each other.

  Here, in a configuration that does not have a function of rotating the holding unit 4 holding the bobbin 10 in conjunction with the rotation of the winding unit 3, every time the arm 31 b goes around the core 100 once (winding) Each time the portion 3 rotates once), the two wire rods 200 are twisted once each other. For this reason, in this configuration, it is difficult to wind the two wires 200 around the core 100 in an orderly manner. On the other hand, in this winding machine 1, the holding unit 4 rotates at the same rotational speed as that of the winding unit 3 in conjunction with the rotation of the winding unit 3, so that the two wire rods 200 are twisted together. Is avoided. Therefore, in this winding machine 1, as shown in FIG. 4, it is possible to wind the two wire rods 200 around the core 100 in an orderly manner (at equal intervals).

  Further, in the winding machine 1, the winding unit 3 and the holding unit 4 are arranged so that the central axis X <b> 1 serving as the rotation center of the winding unit 3 and the central axis X <b> 2 serving as the rotation center of the holding unit 4 are coaxial with each other. Has been placed. In this case, when both the central axes X1 and X2 are not coaxial, a guide part such as a roller is necessary to smoothly guide the wire rod 200 fed from the bobbin 10 held by the holding part 4 to the winding part 3. It becomes. On the other hand, in this winding machine 1, since both central axis lines X1 and X2 are coaxial, the wire 200 can be smoothly guided to the winding part 3 without providing such a guide part. The configuration of the winding machine 1 can be sufficiently simplified.

  Further, in the winding machine 1, excessive rotation of the bobbin 10 is restricted by the rotation restriction unit 8. For this reason, in this winding machine 1, as a result of preventing the slack of the wire 200 due to excessive rotation of the bobbin 10, it is possible to prevent the wire 200 from being disturbed due to the slack of the wire 200.

  Subsequently, when each wire 200 is wound up to the winding end position in the core 100, the control unit stops the motors 5a, 5b, 71 to rotate the winding unit 3 and the holding unit 4, and the support unit. The movement of 6 (core 100) is terminated. Next, the wire 200 is cut in the vicinity of the winding end position. Thus, the winding of the wire 200 around the core 100 is completed.

  Thus, in this winding machine 1, the holding part 4 holding a plurality of (two in the above example) bobbins 10 is configured to be rotatable about the central axis X2, and the motor 5b is a winding part. The holding unit 4 is rotated at the same rotational speed as the rotational speed 3. For this reason, according to this winding machine 1, the arm 31b of the winding unit 3 supports the plurality of (in the above example, two) wire rods 200 fed from the bobbins 10 around the core 100. It is possible to reliably avoid twisting between the wire rods 200 when they circulate. Therefore, according to the winding machine 1, a plurality of wires 200 can be wound around the core 100 in an orderly manner (equally at equal intervals).

  Moreover, according to this winding machine 1, the winding part 3 and the holding part are arranged such that the central axis X1 that is the rotation center of the winding part 3 and the central axis X2 that is the rotation center of the holding part 4 are parallel to each other. By arranging 4, a guide unit such as a roller can be simply configured to smoothly guide the wire 200 fed from the bobbin 10 held by the holding unit 4 to the winding unit 3.

  Moreover, according to this winding machine 1, the winding part 3 and the holding part are arranged such that the central axis X1 as the rotation center of the winding part 3 and the central axis X2 as the rotation center of the holding part 4 are coaxial with each other. 4 is arranged, the wire 200 is attached to the winding part 3 without providing a guide part for guiding each wire 200 fed out from each bobbin 10 held by the holding part 4 to the winding part 3. You can guide smoothly. Therefore, according to the winding machine 1, the configuration of the winding machine 1 can be sufficiently simplified because the guide portion is unnecessary.

  In addition, according to the winding machine 1, the wire rod due to excessive rotation of the bobbin 10 is provided by including the rotation limiting unit 8 that restricts the rotation of the bobbin 10 when the wire rod 200 is fed by applying a load to the bobbin 10. As a result of reliably preventing the slack of the wire 200, it is possible to reliably prevent the wire 200 from being disturbed due to the slack of the wire 200.

  Moreover, according to this winding machine 1, by providing the moving mechanism 7 which moves the support part 6 along the winding direction at a speed according to the rotational speed of the winding part 3, for example, by the winding part 3 While the winding is performed once, the moving mechanism 7 moves the support portion 6 so that the core 100 moves along the length direction by one pitch P of the winding, so that the respective wire rods 200 overlap each other. And can be wound around the core 100 at equal intervals.

  The configuration of the winding machine is not limited to the above configuration. For example, although the configuration example in which the two wire rods 200 are wound around the core 100 at a time has been described above, a configuration in which three or more wire rods 200 are wound at a time may be employed. In this configuration, the holding unit 4 is configured so as to be able to hold the bobbins 10 corresponding to the number of wires 200 to be wound, and the winding unit 3 is configured so as to be able to support the wires 200 fed out from these bobbins 10 respectively. An effect similar to that of the winding machine 1 can be realized.

  Further, the central axis X1 (rotation center of the winding unit 3) of the rotating shaft 32 in the winding unit 3 and the central axis X2 (rotation center of the holding unit 4) of the holding shaft 43 in the holding unit 4 are coaxial. The example in which the winding part 3 and the holding part 4 are arranged has been described above, but both the central axes X1 and X2 are parallel and misaligned (not coaxial), and both the central axes X1 and X2 are not parallel. The structure which arrange | positions the winding part 3 and the holding | maintenance part 4 in a state can also be employ | adopted. In such a configuration, by providing a guide portion such as a roller for guiding the wire rod 200 fed out from the bobbin 10 held by the holding portion 4 to the winding portion 3, the wire rod 200 can be smoothly moved with respect to the winding portion 3. Can be guided to.

  Further, the example in which the rotation restricting portion 8 that restricts the rotation of the bobbin 10 when the wire rod 200 is fed by applying a load to the bobbin 10 by pressing the flange 10b of the bobbin 10 with the tip of the rod 81 has been described above. However, the configuration of the rotation limiting unit is not limited to this. For example, a rotation limiting unit that applies a load to the bobbin 10 by pressing or holding the holding shaft 43 that holds the bobbin 10 to limit the rotation of the bobbin 10 may be employed.

  Moreover, when winding the wire 200 around the core 100, the configuration example in which the support portion 6 is moved along the winding direction has been described above, but the winding portion 3 is moved along the winding direction without moving the support portion 6. It is also possible to adopt a configuration that allows Moreover, the structure which moves both the support part 6 and the winding part 3 is also employable. Furthermore, instead of the configuration in which the support unit 6 is moved by the moving mechanism 7, a configuration in which the support unit 6 (or the winding unit 3 or both the support unit 6 and the winding unit 3) is manually moved is adopted. You can also

  Moreover, the winding object which winds the wire 200 is not limited to the above-mentioned core 100, For example, the core and bobbin for motors can be made into the winding object.
