Description

  The present invention relates to a winding device and a winding method.

  2. Description of the Related Art In a wire rod manufacturing process, a device for winding a wire rod around a bobbin is used. This winding device is configured to be capable of multilayer winding of a wire rod on a bobbin by reciprocating in the axial direction while rotating the bobbin. Specifically, this winding device arranges and winds a wire from one end side to the other end in the axial direction on the body of a rotating bobbin, and winds the wire from an existing layer at a position in contact with the flange of the bobbin. Then, the wire is turned upside down from the position where the layer is raised, and the wire is aligned and wound in the axial direction to form a multilayer aligned winding.

  However, in this winding device, there is a possibility that a gap may be formed between the flange portion of the bobbin and the wire at a position where the wire is raised from the existing layer, or an overlap may occur between adjacent wires.

  Based on such a problem, a “winding device and a winding method for a flat wire” have been proposed today (see Japanese Patent Application Laid-Open No. 2010-6585). The winding device described in this publication variably controls the reciprocating movement speed of the bobbin, and reduces the gap between the wire and the flange portion of the bobbin, and the gap between the wires by pressing the wire with a wire pressing roller. The overlap between adjacent wires can be suppressed by adjusting the distance between the wires or between the wires and the flange.

  However, the winding device described in the above publication has a problem that it is difficult to prevent the wire rod from climbing up (wire riding) or dropping of the wire rod (line dropping) due to disturbance. More specifically, this winding device corresponds to the convex portion when irregularities are formed on the inner surface of the flange portion of the bobbin (the surface on the body portion side of the bobbin) due to thermal deformation or the like during use. In some parts, the wire rod hits the flange part and hits faster than set, or the gap between the wire material and the flange part increases in the part corresponding to the concave part, the wire material in the rising part falls into the flange part, and the wire drop May occur. Further, when such a riding or dropping occurs, there is a high possibility that further riding or dropping occurs in the subsequent winding process of the wire.

  The present invention has been made based on the above-described circumstances, and an object of the present invention is to provide a winding device and a winding method for a wire that can easily and reliably suppress the riding and dropping of the wire. And

  A winding device according to an aspect of the present invention made to solve the above problem includes a bobbin driving mechanism that reciprocates a bobbin having a cylindrical body and a flange on both sides thereof in the axial direction. A winding device for winding a wire in a multi-layer arrangement, comprising a camera for photographing a bobbin from a tangential direction of a body, and a control unit for setting a timing of reciprocating movement of the bobbin based on an image photographed by the camera.

  A winding method according to another aspect of the present invention made in order to solve the above problem is to reciprocate a bobbin having a cylindrical body portion and flange portions on both sides thereof in the axial direction, and to form a multilayered wire on the bobbin. A winding method for aligning and winding, comprising: a photographing step of photographing a bobbin from a tangential direction of a body part; and a control step of setting timing of reciprocating movement of the bobbin based on an image photographed in the photographing step.

[Description of Embodiment of the Present Invention]
A winding device according to an aspect of the present invention made to solve the above problem includes a bobbin driving mechanism that reciprocates a bobbin having a cylindrical body and a flange on both sides thereof in the axial direction. A winding device for winding a wire in a multi-layer arrangement, comprising a camera for photographing a bobbin from a tangential direction of a body, and a control unit for setting a reciprocating timing of the bobbin based on an image photographed by the camera.

  The winding device is provided with a camera for photographing the bobbin from the tangential direction of the body, and this camera can photograph an image of the wire rod riding on the existing layer. Further, since the winding device includes a control unit that sets the timing of the reciprocating movement of the bobbin based on the image captured by the camera, it is possible to control the reciprocating movement of the bobbin based on the climbing of the wire. The winding device does not reciprocate the bobbin according to a prescribed program, but controls the reciprocal movement of the bobbin based on the climbing of the wire rod (that is, based on actual measurement data). Even when unevenness is formed on the inner surface of the portion, it is easy to suppress line riding and line drop based on the unevenness. For this reason, the winding device can easily and reliably prevent the wire rod from riding or dropping.

  The winding device may further include a displacement sensor that measures an axial distance of the flange of the bobbin with respect to the wire. As described above, by further including the displacement sensor that measures the axial distance between the bobbin and the flange relative to the wire, the reciprocating movement of the bobbin can be more accurately controlled based on the axial distance between the wire and the flange. .

  The winding device may further include a wire alignment mechanism for urging the wire toward the flange portion when the wire is wound on the bobbin, and the displacement sensor may be attached to the wire alignment mechanism. As described above, the wire rod is further provided with a wire alignment mechanism that urges the wire toward the flange when being wound on the bobbin, and the displacement sensor is attached to the wire alignment mechanism, so that the shaft of the wire and the flange is provided. Direction spacing can be measured easily and reliably.

  The control unit may reversely move the bobbin when the bobbin rotates by 150 ° or more and 300 ° or less based on the position at which the wire rod rides on the existing layer. In this way, the control unit reversely moves the bobbin when the bobbin rotates at an angle within the above range with reference to the position where the wire rod rides on the existing layer, so that the outer surface of the raised position and the layer rise The flattening with the outer surface other than the set position can be promoted, and the wire can be smoothly fed out after winding.

  Another invention made in order to solve the above-mentioned problem is a winding method in which a bobbin having a cylindrical body and flanges on both sides thereof is reciprocated in an axial direction, and a wire material is wound around the bobbin in a multilayer alignment. There is provided a photographing step of photographing the bobbin from the tangential direction of the body, and a control step of setting the timing of the reciprocation of the bobbin based on the image photographed in the photographing step.

  Since the winding method includes a photographing step of photographing the bobbin from the tangential direction of the trunk, an image of the wire rod riding on the existing layer can be photographed by the photographing step. Further, since the winding method includes a control step of setting the timing of the reciprocating movement of the bobbin based on the image captured in the capturing step, the reciprocating movement of the bobbin can be controlled based on the climbing of the wire. For this reason, the winding method can easily and surely prevent the wire rod from riding or dropping as described above.

[Details of Embodiment of the Present Invention]
Hereinafter, a winding device and a winding method according to the present invention will be described in detail with reference to the drawings.

[First embodiment]
<Rewinding device>
The winding device 1 of FIG. 1 includes a bobbin driving mechanism 12 that reciprocates a bobbin 11 having a cylindrical body portion 11a and flange portions 11b on both sides in the axial direction, and winds the wire X around the bobbin 11 in a multi-layer arrangement. It is a winding device. The winding device 1 includes a traverser 2 having a bobbin driving mechanism 12 and a bobbin rotating mechanism 13 for rotating the bobbin 11, a camera 3 for photographing the bobbin 11 from a tangential direction of the body 11a, and an image captured by the camera 3. And a controller 4 for setting the timing of the reciprocating movement of the bobbin 11 based on the timing.

  The winding device 1 includes a camera 3 that photographs the bobbin 11 from the tangential direction of the trunk 11a, and this camera 3 can capture an image of the wire X riding on the existing layer. Further, since the winding device 1 includes the control unit 4 that sets the timing of the reciprocating movement of the bobbin 11 based on the image captured by the camera 3, the reciprocating movement of the bobbin 11 is performed based on the climbing of the wire X. Can be controlled. The winding device 1 does not reciprocate the bobbin 11 according to a prescribed program, but controls the reciprocating movement of the bobbin 11 based on the climbing of the wire X (that is, based on actual measurement data). In addition, even when irregularities are formed on the inner surface of the flange 11b of the bobbin 11, it is easy to suppress line riding and line drop based on the irregularities. Therefore, the winding device 1 can easily and reliably suppress the riding and dropping of the wire X.

  The wire X is wound around the body 11a of the bobbin 11 via the arm guide Y. Although the wire X may be a flat wire or a round wire, the effect of the winding device 1 is more exhibited by using the flat wire. Although the type of the wire X is not particularly limited, for example, a coated electric wire such as an enameled wire obtained by baking and coating an insulating paint on a single core wire made of a metal conductor such as copper is preferably used. Although the thickness and width of the wire X are not particularly limited, the winding device 1 preferably winds, for example, a wire having an average thickness of 0.5 mm to 5 mm and an average width of 1 mm to 10 mm. Can be taken.

(Traversa)
The traverser 2 includes the above-described bobbin driving mechanism 12 and bobbin rotating mechanism 13, and a support base 14 serving as a pedestal.

  The support base 14 is a base on which the bobbin drive mechanism 12 and the bobbin rotation mechanism 13 are placed, and is located at the lowermost part of the traverser 2.

  The bobbin driving mechanism 12 has a screw shaft 12a, a moving table 12b, and a position control motor 12c.

  The screw shaft 12a is a shaft in which a spiral groove (screw groove) is carved, one end of which is screwed to the moving table 12b, and the other end of which is joined to the shaft of the position control motor 12c.

  The moving table 12b has a screw hole screwed with the screw shaft 12a, and is provided on the support table 14 so as to move in the axial direction of the screw shaft 12a in accordance with the rotation of the screw shaft 12a.

  The position control motor 12c is a motor that rotates the screw shaft 12a. The position control motor 12c can rotate forward and backward. By rotating the screw shaft 12a by the position control motor 12c, the movable table 12b moves in the axial direction of the screw shaft 12a. Further, the moving table 12b can be reciprocated by changing the rotation direction of the position control motor 12c.

  The bobbin rotation mechanism 13 has a spindle 13a for attaching the bobbin, a bearing member 13b for rotatably supporting the spindle 13a, and a rotation motor 13c for rotating the spindle 13a via a gear 13d.

  The spindle 13a is a columnar member that transmits the rotation power of the rotation motor 13c to the bobbin 11. The spindle 13a is configured to be attachable to the inside of the body of the bobbin 11 so that the axial directions thereof coincide with each other. The spindle 13a is disposed so that the axial direction of the spindle 13a matches the axial direction of the screw shaft 12a.

  The bearing member 13b is a bearing that rotatably supports the spindle 13a. The bobbin rotating mechanism 13 rotates the bobbin 11 by rotating the spindle 13a on which the bobbin 11 is mounted while the spindle 13a is supported by the bearing material 13b.

  The rotation motor 13c is provided on the movable base 12b, and is connected to the spindle 13a via a gear 13d. The wire X is wound around the bobbin 11 by the rotation motor 13c rotating the spindle 13a. The rotation motor 13c may be configured to have a variable rotation speed, or may be configured to have a constant rotation speed.

  Since the traverser 2 is configured as described above, the winding device 1 can reciprocate the bobbin 11 by the bobbin driving mechanism 12 by reciprocating the movable table 12b using the position control motor 12c. it can. In addition, the winding device 1 can rotate the bobbin 11 by the bobbin rotation mechanism 13 by mounting the bobbin 11 on the spindle 13a and rotating the spindle 13a using the rotation motor 13c. Therefore, the winding device 1 is configured such that the wire X supplied from the arm guide Y whose position is fixed in the direction perpendicular to the axial direction of the bobbin 11 is multilayered on the bobbin 11 by rotating the bobbin 11 and reciprocating in the axial direction. Can be wound up. Known traversers 2 can be used.

(camera)
The camera 3 is disposed so that the bobbin 11 can be photographed from the tangential direction of the body 11a. In the present embodiment, the camera 3 is wound around the body 11a from a direction perpendicular to the axial direction of the bobbin 11, as shown in FIG. The wire X is arranged so as to be able to take a picture. Further, the camera 3 is configured to be able to continuously photograph the wire X at a position near the inner surface (opposing surface) of the flange portion 11b, thereby being able to photograph the climbing of the wire X onto an existing layer. ing. As will be described later, the winding device 1 controls the reciprocating movement of the bobbin 11 based on the image captured by the camera 3 after capturing an image of the wire X climbing by the camera 3. For this reason, in the winding device 1, the reciprocating movement of the bobbin 11 is easier to control if the camera 3 can photograph the climbing of the wire X earlier. From such a point, it is preferable that the camera 3 is arranged so as to be able to take an image of the wire X before being wound 210 ° from the point where the wire X supplied from the arm guide Y is stacked on the bobbin 11. As the camera 3, for example, a CCD (Charge Coupled Devices) camera, a CMOS (Complementary Metal Oxide Semiconductor) camera, or the like can be used.

(Control unit)
The control unit 4 can be configured by, for example, a personal computer, a programmable controller, or the like. The control unit 4 sets the reciprocating timing of the bobbin 11 based on the image captured by the camera 3 as described above. More specifically, when the camera 3 captures an image of the wire X climbing onto the existing layer, the control unit 4 drives the bobbin 11 to reverse the bobbin 11 based on the climbing position of the wire X based on the image. The mechanism 12 is controlled.

  A control mechanism for reciprocating the bobbin 11 in the winding device 1 will be described with reference to FIGS. First, the winding device 1 rotates the bobbin 11 in the Z direction, which is the circumferential direction, and moves the bobbin 11 in the axial direction by the bobbin driving mechanism 12 and the bobbin rotating mechanism 13 while moving the wire X supplied from the arm guide Y to the body 11a. And roll it up. Then, the control unit 4 stops the movement of the bobbin 11 in the axial direction when the wire X reaches near the inner surface of the flange 11b. The procedure for stopping the movement of the bobbin 11 in the axial direction is not particularly limited. For example, the axial distance between the wire X and the flange portion 11b is measured. May be stopped in the axial direction.

  Next, when the movement of the bobbin 11 in the axial direction is stopped, the wire X is wound around a portion of the body 11a of the bobbin 11 near the inner surface of the flange portion 11b. Then, as shown in FIG. 2, the vehicle rides on the existing layer at the position X1.

  Further, the wire X is wound around a portion of the body 11a of the bobbin 11 near the inner surface of the flange 11b even after riding on the existing layer at the riding position X1. Then, as shown in FIG. 3, after riding on the existing layer, when the film is wound at a predetermined angle, the rising portion reaches the shooting area of the camera 3. On the other hand, since the camera 3 continuously shoots the bobbin 11 from the tangential direction of the body 11a, the camera 3 takes a ride-up image shown in FIG. When the camera 3 captures a climbing image, the control unit 4 recognizes the climbing of the wire X by image processing and uses the climbing position X1 of the wire X on the existing layer as a reference (that is, the climbing position). (X1 is set to 0 °) Based on the rotation angle of the bobbin 11, the reverse movement control of the bobbin 11 is performed. Note that the camera 3 may perform the above-described image processing, and the control unit 4 may receive the image processing data and perform the reverse movement control of the bobbin 11.

  It is preferable that the lower limit of the angle at which the bobbin 11 starts reversing movement with respect to the position X1 at which the wire X rides on the existing layer is 150 ° and the upper limit be 300 °. If the angle is less than the lower limit, the reversal movement of the bobbin 11 is too fast, the thickness of the wire X at the position where the bobbin 11 has risen is insufficient, and the wire X may not be smoothly fed out after winding. . Conversely, when the angle exceeds the upper limit, the layer thickness of the wire X at the position where the layer is raised becomes large, and it may be difficult to smoothly unwind the wire X after winding. The rotation angle of the bobbin 11 from the point at which the wire X is stacked on the bobbin 11 until the image is captured by the camera 3 is stored in the control unit 4 in advance. The reversing movement of the bobbin 11 is performed by the control unit 4 controlling the bobbin driving mechanism 12 to reversely move the bobbin 11 when the rotation angle of the bobbin 11 with respect to the lamination point reaches a predetermined value. .

<Rewinding method>
Next, a winding method according to the present invention will be described. The winding method is a winding method in which a bobbin having a cylindrical body portion and flange portions on both sides thereof is reciprocated in an axial direction, and a wire is wound on the bobbin in a multi-layer arrangement, and the winding device shown in FIG. 1 can be performed. The winding method includes a photographing step of photographing the bobbin 11 from a tangential direction of the body 11a, and a control step of setting a reciprocating timing of the bobbin 11 based on the image photographed in the photographing step.

(Shooting process)
The photographing process is performed by the camera 3. In the above-mentioned photographing process, the bobbin 11 is continuously photographed from the tangential direction of the trunk portion 11a, thereby photographing an image of the wire X riding on the existing layer.

(Control process)
The control step is performed by the control unit 4. In the control step, the bobbin driving mechanism 12 is controlled so that the bobbin 11 is reversed based on the riding position X1 based on the image of the wire X riding on the existing layer captured in the imaging step. In the control step, it is preferable to stop the movement of the bobbin 11 in the axial direction when the wire X reaches the vicinity of the inner surface of the flange 11b before the bobbin 11 is reversed.

  Since the winding method includes a photographing step of photographing the bobbin 11 from the tangential direction of the body 11a, an image of the wire X riding on the existing layer can be photographed by the photographing step. Further, since the winding method includes a control step of setting the timing of the reciprocating movement of the bobbin 11 based on the image captured in the photographing step, it is possible to control the reciprocating movement of the bobbin based on the climbing of the wire X. it can. For this reason, the winding method can easily and surely prevent the wire X from riding or dropping as described above.

[Second embodiment]
<Rewinding device>
The winding device 21 of FIG. 5 includes a traverser 2, a camera 3 for photographing the bobbin 11 from a tangential direction of the body 11a, and a wire alignment for urging the wire X to the flange 11b side when wound on the bobbin 11. A mechanism 22, a pair of displacement sensors 23 for measuring an axial distance of the flange portion 11b with respect to the wire X, and a timing of reciprocating movement of the bobbin 11 based on an image taken by the camera 3 and an interval measured by the pair of displacement sensors 23. And a control unit 24 for setting The traverser 2 and the camera 3 in the winding device 21 are the same as those in the winding device 1 in FIG.

(Wire rod alignment mechanism)
The wire rod alignment mechanism 22 has a pair of roller units 31. Each roller unit 31 is provided in parallel with the axis of the bobbin 11, and is provided with a shaft portion that reciprocates in the axial direction, and a roller that is provided at the tip of the shaft portion and urges the wire X when being wound. And a part.

  The pair of roller units 31 are disposed on the frame 32 via a reciprocating mechanism and a separating mechanism, whereby the pair of roller units 31 can be separated from the bobbin 11 and reciprocally move in the axial direction of the bobbin 11. I have. Specifically, the wire rod aligning mechanism 22 includes a frame 32 as a support table, a movable table 33 disposed on the frame 32 so as to be movable in the axial direction of the bobbin 11, and a rotating plate 33 protruding from the movable table 33. A pair of actuators 34 disposed so that the axis directions of the shafts coincide with the moving direction of the moving table 33, a pair of arm portions 35 connected to the rotation shafts of the pair of actuators 34, and a pair of arm portions 35 And a pair of roller units 31.

  The frame 32 supports the movable table 33 so as to be reciprocally movable in the axial direction of the bobbin 11 (the left-right direction in the figure). At both ends of the frame 32, stopper plates for restricting the movement of the moving table 33 are provided.

  The moving table 33 reciprocates the pair of roller units 31 in the axial direction of the bobbin 11. As a moving mechanism of the moving table 33, a configuration similar to that of the above-described bobbin driving mechanism 12 can be adopted.

  The pair of actuators 34 are respectively disposed on a pair of plate portions disposed on the upper surface of the moving table 33 so as to face the moving direction. The pair of actuators 34 are disposed so that the axial direction of the rotating shaft coincides with the moving direction of the moving table 33 (the axial direction of the bobbin 11), and the pair of arm portions 35 are respectively perpendicular to the axial direction of the bobbin 11. It is possible to move within a simple plane.

  Each of the pair of arm portions 35 is configured to be movable in a plane perpendicular to the axial direction of the bobbin 11. Specifically, each of the pair of arms 35 has a main body having one end connected to the actuator 34 and a roller support connected to the other end of the main body. Are connected so as to be rotatable in a direction perpendicular to the axial direction.

  The pair of roller units 31 are configured to be able to press the wire X against the flange 11 b of the bobbin 11. Each of the pair of roller units 31 is provided with a roller via a shaft so that the rotation axis is parallel to the axial direction of the bobbin 11 and the roller is disposed on the side opposite to the facing surface of the pair of arms 35. It is rotatably supported by the support part.

  As shown in FIG. 6, the pair of roller units 31 are coaxially disposed at the tip of the shaft portion as the above-described roller portion, and the large-diameter roller 36 whose tip can abut on the side surface of the wire rod X; A small-diameter roller 37 is provided coaxially on the distal end side of the diameter roller 36 and has a peripheral surface that can contact the outer periphery of the wire X.

(Displacement sensor)
Each displacement sensor 23 has a light source capable of emitting laser light and a detection unit capable of detecting reflected light of the laser light emitted from the light source. The pair of displacement sensors 23 are attached to the wire rod alignment mechanism 22. More specifically, the pair of displacement sensors 23 are configured such that the light emission direction of the light source is outward (the direction opposite to the direction in which the pair of arms 35 opposes) and coincides with the axial direction of the shaft. Attached to. Thereby, each displacement sensor 23 is configured such that the light source can emit laser light to the inner surface of the flange 11b, and the detection unit detects the reflected light reflected by the flange 11b. The distance between the displacement sensor 23 and the inner surface of the flange 11b can be measured.

(Control unit)
The control unit 24 can be configured by, for example, a personal computer, a programmable controller, or the like. When the camera 3 captures an image of the wire X climbing onto the existing layer, the control unit 24 determines the climbing position of the wire X based on this image, similarly to the control unit 4 of the winding device 1 in FIG. The bobbin driving mechanism 12 is controlled so that the bobbin 11 is reversed. Further, the control unit 24 is configured to stop the reciprocating movement of the bobbin 11 based on the interval measured by the pair of displacement sensors 23. Specifically, the control unit 24 determines the outer side surface of the wire X wound around the bobbin 11 (the side of the flange 11b) from the distance between the displacement sensor 23 measured by the pair of displacement sensors 23 and the inner surface of the flange 11b. And the inner surface of the flange portion 11b is calculated, and the movement of the bobbin 11 can be stopped when the distance becomes equal to or less than a predetermined value (for example, a value smaller than the width of the wire X).

  With reference to FIGS. 6 and 7, a mechanism for measuring the axial distance between the wire X and the flange 11b in the winding device 21 will be described. First, as shown in FIG. 6, when the wire X is wound on one of the flanges 11 b of the bobbin 11, the winding device 21 includes a small-diameter roller 37 of a pair of roller units 31 of the wire alignment mechanism 22. Is arranged so that one of the roller units 31 located on the side of the one flange portion 11b is along the outer periphery of the wound wire X. Then, the displacement sensor 23 attached to the arm portion 35 of the one roller unit 31 continuously measures the distance D between the displacement sensor 23 and the inner surface of the flange portion 11b. Is measured in the axial direction. Then, as shown in FIG. 7, when the distance D between the displacement sensor 23 and the inner surface of the flange 11b becomes equal to or less than a predetermined value, the control unit 24 determines that the wire X has reached the vicinity of the flange 11b and sets the bobbin. 11 is stopped. In the winding device 21, the distance between the outer side surface (the side surface on the side of the flange 11b) of the wire X and the inner surface of the flange 11b may be measured based on the distance D. The winding device 21 measures the distance D while keeping the axial distance between the displacement sensor 23 and the outer side surface of the wire X constant, and from these values, the outer side surface of the wire X and the flange 11b are measured. An accurate distance from the inner surface may be calculated.

  In addition, when the bobbin 11 reversely moves, the one roller unit 31 causes the peripheral surface of the small-diameter roller 37 to abut on the outer surface of the wire X wound around the bobbin 11, and the side surface of the large-diameter roller 36 ( The small-diameter roller 37 side is brought into contact with the side surface of the wire X to press the wire X toward the flange 11b of the bobbin 11, thereby controlling the gap between the wires X.

  The winding device 21 includes the displacement sensor 23 that measures the axial distance of the flange 11b with respect to the wire X, so that the movement of the bobbin 11 can be stopped based on the axial distance between the wire X and the flange 11b. it can. Since the winding device 21 does not stop the movement of the bobbin according to the prescribed program but stops the movement of the bobbin 11 based on the actually measured data, irregularities are formed on the inner surface of the flange 11b. Even in this case, it is easy to suppress the line riding and line dropping based on the unevenness. Therefore, the winding device 21 can more accurately control the reciprocating movement. In addition, the winding device 21 can easily and reliably measure the axial distance between the wire X and the flange 11b because the displacement sensor 23 is attached to the wire alignment mechanism 22.

  When the wire X is wound on the other side of the bobbin 11, the small diameter roller 37 of the pair of roller units 31 of the wire aligning mechanism 22 winds the other roller unit 31 located on the other flange 11b side. What is necessary is just to arrange | position along the outer periphery of the wire X to be taken, and measure the axial distance of the flange part 11b with respect to the wire X by the displacement sensor 23 attached to the arm part 35 of this other roller unit 31.

<Rewinding method>
Next, a winding method using the winding device 21 of FIG. 5 will be described. The winding method includes a control step of setting the timing of reciprocal movement of the bobbin 11 based on an image captured by the camera 3 and an interval measured by the pair of displacement sensors 23, and capturing the bobbin 11 from a tangential direction of the body 11a. And a photographing step. The control step includes a movement stopping step of stopping the movement of the bobbin 11, and a reversing movement step of reversing the bobbin 11. The winding method is performed in the order of the movement stopping step, the photographing step, and the reversing moving step. The photographing step is the same as the photographing step in the above-described first embodiment, and the reversal moving step is the same as the control step in the above-described first embodiment, and thus the description is omitted.

(Transfer stop process)
The movement stopping step is performed by the pair of displacement sensors 23 and the control unit 24. In the movement stop step, first, the pair of displacement sensors 23 continuously measure the distance between the pair of displacement sensors 23 and the inner surface of the flange 11b, thereby measuring the axial distance of the flange 11b with respect to the wire X. I do. Further, in the movement stop step, when the distance between the pair of displacement sensors 23 and the inner surface of the flange 11b becomes equal to or less than a predetermined value, the control unit 24 determines that the wire X has reached the vicinity of the flange 11b. The reciprocation of the bobbin 11 is stopped.

  Since the winding method includes the movement stopping step, the axial movement of the bobbin 11 can be stopped easily and reliably at a position where the wire X has reached the vicinity of the flange 11b. For this reason, the winding method can more appropriately suppress the riding and dropping of the wire X (particularly, the riding and dropping of the wire X caused by unevenness of the inner surface of the flange portion 11b).

[Other Embodiments]
The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is not limited to the configuration of the above-described embodiment, but is indicated by the appended claims, and is intended to include all modifications within the scope and meaning equivalent to the appended claims. You.

  For example, even when the winding device includes the displacement sensor, the displacement sensor does not necessarily need to be attached to the wire alignment mechanism. The winding device may be attached to, for example, the above-described arm guide. Further, the wire rod aligning mechanism in the winding device is not limited to the configuration of the above-described embodiment. For example, the wire rod aligning mechanism is disposed coaxially at the tip of the shaft portion, a small-diameter roller whose peripheral surface is in contact with the outer periphery of the wire rod, and coaxially disposed at the distal end side of the small-diameter roller, and the rear end face of the wire rod A pair of pulling roller units (a roller unit that pulls the wire toward the flange of the bobbin) having a large-diameter roller abutting on the side surface may be provided. In this case, the pair of displacement sensors may be attached to the arm portions of the pair of traction roller units.

  The winding device may be configured to photograph or predict a position where the wire rod climbs onto the existing layer, and stop the movement of the bobbin at this climbing position.

  INDUSTRIAL APPLICABILITY The winding device according to the present invention is suitable as an automatic winding device for a wire rod because it can easily and reliably suppress the wire riding and dropping of the wire rod.
