Description
Technical Field
The present invention relates to a winding device and a winding method. The priority of Japanese application No. 2016-.
Background
In the wire rod manufacturing process, a device for winding a wire rod on a winding drum is used. The winding device is configured to wind the wire material in a multi-layer arrangement on the winding drum by rotating the winding drum and reciprocating the winding drum in the axial direction. Specifically, the winding device winds the wire material in a multi-layer arrangement by arranging the wire material in a main body portion of a rotating winding drum from one axial end side to the other axial end side, raising the wire material from an existing layer at a position in contact with a flange portion of the winding drum, and then reversing the winding drum from the raised position to arrange the wire material in the axial direction and wind the wire material.
However, the winding device may cause a gap to be formed between the flange portion of the winding drum and the wire material at a position of the winding device where the wire material is raised from the existing layer, or cause overlapping between the adjacent wire materials.
In view of such a problem, a "winding device and a winding method of a flat wire" have been proposed (see japanese patent application laid-open No. 2010-6585). The winding device described in this publication controls the reciprocating speed of the winding drum to be variable, and presses the wire material with the wire pressing roller, thereby reducing the gap between the wire material and the flange portion of the winding drum and the gap between the wire materials, and further, adjusting the gap between the wire materials or the gap between the wire material and the flange portion to suppress the overlapping between the adjacent wire materials.

Detailed Description
Problems to be solved by the invention
The winding device described in the above publication has a problem that it is difficult to prevent the rising of the wire material (wire rising) and the sinking of the wire material (wire falling) due to the disturbance. Specifically, in the case where the inner surface of the flange portion of the winding drum (the surface on the main body side of the winding drum) has irregularities due to thermal deformation or the like during use, the wire may come into contact with the flange portion earlier than set at a portion corresponding to the irregularities to cause a rise in the wire, or the gap between the wire and the flange portion may increase at a portion corresponding to the indentations to cause a fall of the wire in the rising portion toward the flange portion. Further, when such a line start or line fall occurs, there is a high possibility that further line start or line fall occurs in the subsequent winding process of the wire rod.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a winding device and a winding method for a wire rod, which can easily and reliably suppress the rise and fall of the wire rod.
[ Effect of the invention ]
The invention provides a winding device and a winding method, which can easily and reliably inhibit the line rising and line falling of a wire rod.
[ description of embodiments of the invention ]
A winding device according to an aspect of the present invention, which has been made to solve the above problems, includes a winding drum driving mechanism that reciprocates a winding drum having a cylindrical body portion and flange portions on both sides thereof in an axial direction of the winding drum, and winds a wire material in a multi-layer arrangement on the winding drum, the winding device including: a camera for shooting the winding drum from the tangential direction of the main body part; and a control unit that sets a timing of the reciprocating movement of the winding drum based on the image captured by the camera.
The winding device is provided with a camera for shooting the winding drum from the tangential direction of the main body part, so that the camera can shoot the climbing image of the wire rod to the existing layer. Further, since the winding device includes the control unit that sets the timing of the reciprocation of the winding drum based on the image captured by the camera, the reciprocation of the winding drum can be controlled based on the ascent of the wire rod. This winding device is not a device that reciprocates the winding drum by a predetermined program, but a device that controls the reciprocation of the winding drum based on the climb of the wire material (that is, based on measured data), and therefore, even when the unevenness is formed on the inner surface of the flange portion of the winding drum, the rise and fall of the wire due to the unevenness are easily suppressed. Therefore, the winding device can easily and reliably prevent the wire from rising or falling.
Preferably, the winding device further includes a displacement sensor for measuring an axial distance between the flange portion of the winding drum and the wire material. In this way, by further providing a displacement sensor that measures the axial distance between the flange portion of the winding drum and the wire material, the reciprocating movement of the winding drum can be controlled more accurately based on the axial distance between the wire material and the flange portion.
Preferably, the winding device further includes a wire material aligning mechanism that biases the wire material toward the flange portion when the wire material is wound on the winding drum, and the displacement sensor is attached to the wire material aligning mechanism. In this way, by further including the wire arranging mechanism for biasing the wire toward the flange portion when the wire is wound around the winding drum, and by attaching the displacement sensor to the wire arranging mechanism, the axial distance between the wire and the flange portion can be easily and reliably measured.
Preferably, the control unit reverses the winding drum when the winding drum rotates by 150 ° to 300 ° with reference to a position where the wire rod climbs to the existing layer. In this way, the control unit can promote flattening of the outer surface at the post-lifting position and the outer surface other than the post-lifting position by reversing the winding drum when the winding drum is rotated by the angle within the range with the lifting position of the wire rod to the existing layer as a reference, and can smoothly discharge the wire rod after winding.
Another aspect of the present invention made to solve the above problems is a winding method for winding a wire material in a multi-layer arrangement on a winding drum having a cylindrical body portion and flange portions on both sides thereof, while reciprocating the winding drum in an axial direction of the winding drum, the winding method including: an imaging step of imaging the winding drum from a tangential direction of the main body; and a control step of setting the timing of the reciprocating movement of the winding drum based on the image captured in the imaging step.
Since this winding method includes an imaging step of imaging the winding drum from the tangential direction of the main body, an image of the climbing of the wire rod to the existing layer can be imaged by the imaging step. Further, since the winding method includes the control step of setting the timing of the reciprocating movement of the winding drum based on the image captured in the imaging step, the reciprocating movement of the winding drum can be controlled based on the climb of the wire rod. Therefore, the winding method can easily and reliably suppress the wire rising and falling of the wire material as described above.
[ details of embodiments 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 ]
< winding device >
The winding device 1 shown in fig. 1 includes a winding drum driving mechanism 12 for axially reciprocating a winding drum 11 having a cylindrical body portion 11a and flange portions 11b on both sides thereof, and winds the wire X in a multi-layer arrangement on the winding drum 11. The winding device 1 includes: a movable platform (diverter) 2 having a winding drum driving mechanism 12 and a winding drum rotating mechanism 13 for rotating the winding drum 11; a camera 3 that photographs the winding drum 11 from a tangential direction of the main body 11 a; and a control unit 4 for setting the timing of the reciprocation of the winding drum 11 based on the image captured by the camera 3.
The winding device 1 includes the camera 3 that images the winding drum 11 from the tangential direction of the main body 11a, so that the camera 3 can image the climbing image of the wire X to the existing layer. In addition, since the winding device 1 includes the control unit 4 that sets the timing of the reciprocation of the winding drum 11 based on the image captured by the camera 3, the reciprocation of the winding drum 11 can be controlled based on the ascent of the wire material X. In this winding device 1, the winding drum 11 is controlled to reciprocate based on the rising of the wire material X (that is, based on the measured data) without reciprocating the winding drum 11 by a predetermined program, and therefore, even when the unevenness is formed on the inner surface of the flange portion 11b of the winding drum 11, the rise and fall of the thread due to the unevenness can be easily suppressed. Therefore, the winding device 1 can easily and reliably suppress the line rising and the line falling of the wire material X.
The wire material X is wound around the main body 11a of the winding drum 11 via the guide arm Y. The wire material X may be a flat wire or a round wire, but the use of a flat wire further exerts the effect of the winding device 1. The type of the wire X is not particularly limited, but for example, a coated electric wire such as an enamel wire in which an insulating varnish is baked and coated on a single core wire made of a metal conductor such as copper can be preferably used. The thickness and width of the wire material X are not particularly limited, but the winding device 1 is preferably configured to wind a wire material having an average thickness of 0.5mm to 5mm, and an average width of 1mm to 10mm, for example.
(Movable platform)
The movable table 2 includes the above-described winding drum driving mechanism 12, winding drum rotating mechanism 13, and support table 14 serving as a base.
The support base 14 is a base on which the winding drum driving mechanism 12 and the winding drum rotating mechanism 13 are placed, and is positioned at the lowermost portion of the movable platform 2.
The winding drum driving mechanism 12 has a screw shaft 12a, a moving table 12b, and a position control motor 12 c.
The screw shaft 12a is a shaft with a spiral groove (a screw groove) formed therein, and has one end screwed to the movable stage 12b and the other end coupled to a shaft of the position control motor 12 c.
The movable table 12b has a screw hole to be screwed with the screw shaft 12a, and is disposed 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 12 a.
The position control motor 12c is a motor that rotates the screw shaft 12 a. The position control motor 12c can rotate forward and backward. By rotating the screw shaft 12a by the position control motor 12c, the moving stage 12b moves in the axial direction of the screw shaft 12 a. Further, the moving stage 12b can be reciprocated by changing the rotation direction of the position control motor 12 c.
The winding drum rotating mechanism 13 includes a main shaft 13a for mounting a winding drum, a bearing member 13b for rotatably supporting the main shaft 13a by the main shaft 13a, and a rotating motor 13c for rotating the main shaft 13a via a gear 13 d.
The main shaft 13a is a cylindrical member for transmitting the rotational power of the rotation motor 13c to the winding drum 11. The main shaft 13a is configured to be attachable so that the inside of the main body portion of the winding drum 11 coincides with the axial direction. The main shaft 13a is disposed so that the screw shaft 12a coincides with the axial direction.
The bearing member 13b is a bearing that supports the main shaft 13a so that the main shaft 13a can rotate freely. The winding drum rotating mechanism 13 rotates the winding drum 11 by rotating the main shaft 13a to which the winding drum 11 is attached in a state where the main shaft 13a is supported by the bearing member 13 b.
The rotation motor 13c is disposed on the movable stage 12b and is connected to the main shaft 13a via a gear 13 d. The rotation motor 13c rotates the main shaft 13a, and the wire material X is wound around the winding bobbin 11. 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 movable platform 2 is configured as described above, in the winding device 1, the winding drum 11 can be reciprocated by the winding drum driving mechanism 12 by reciprocating the movable table 12b by the position control motor 12 c. In the winding device 1, the winding drum 11 is attached to the main shaft 13a, and the main shaft 13a is rotated by the rotation motor 13c, so that the winding drum 11 can be rotated by the winding drum rotating mechanism 13. Therefore, the winding device 1 can wind the wire material X, which is supplied from the guide arm Y at a fixed position in a vertical direction perpendicular to the axial direction of the winding bobbin 11, around the winding bobbin 11 in multiple layers by the rotation and the axial reciprocating movement of the winding bobbin 11. As such a movable platform 2, a known movable platform can be used.
(vidicon)
The camera 3 is arranged to be able to photograph the winding drum 11 from a tangential direction of the main body 11a, and in the present embodiment, is arranged to photograph the wire X wound around the main body 11a from a vertical direction perpendicular to an axial direction of the winding drum 11 as shown in fig. 2. The camera 3 is configured to continuously photograph the wire X at a position near the inner surface (facing surface) of the flange portion 11b, and thereby is configured to photograph the climbing of the wire X to the existing layer. As will be described later, the winding device 1 captures images of the climbing of the wire X by the camera 3, and then controls the reciprocating movement of the winding drum 11 based on the images captured by the camera 3. Therefore, in this winding device 1, the camera 3 can photograph the climb of the wire X at an early stage, and it becomes easy to control the reciprocating movement of the winding drum 11. In this regard, the camera 3 is preferably arranged to capture the line material X before the line material X is wound by 210 ° from the point where the line material X supplied from the guide arm Y overlaps the winding drum 11. As the camera 3, for example, a CCD (Charge Coupled device) camera, a CMOS (Complementary Metal Oxide Semiconductor) camera, or the like can be used.
(control section)
The control unit 4 may be constituted by a personal computer, a programmable controller, or the like, for example. As described above, the control unit 4 sets the timing of the reciprocation of the winding drum 11 based on the image captured by the camera 3. Specifically, when the camera 3 captures an image of the climbing of the wire X to the existing layer, the control unit 4 controls the winding drum driving mechanism 12 to reversely move the winding drum 11 based on the image with the climbing position of the wire X as a reference.
A mechanism for controlling the reciprocation of the winding drum 11 in the winding device 1 will be described with reference to fig. 2 to 4. First, the winding device 1 rotates the winding drum 11 in the circumferential direction, that is, in the Z direction and moves the winding drum in the axial direction by the winding drum driving mechanism 12 and the winding drum rotating mechanism 13, and gradually winds the wire material X supplied from the guide arm Y around the main body portion 11 a. When the wire X reaches the vicinity of the inner surface of the flange portion 11b, the control portion 4 stops the axial movement of the winding drum 11. The procedure for stopping the axial movement of the winding drum 11 is not particularly limited, and for example, the axial movement of the winding drum 11 may be stopped when the axial distance between the wire material X and the flange portion 11b is measured and is fixed or less.
Next, when the movement of the winding drum 11 in the axial direction is stopped, the wire material X is wound around a portion near the inner surface of the flange portion 11b of the main body portion 11a of the winding drum 11, and is wound 360 ° in this portion, as shown in fig. 2, the climbing position X1 climbs onto the existing layer.
Then, the wire rod X is wound around the portion near the inner surface of the flange portion 11b of the body portion 11a of the winding bobbin 11 after climbing up to the existing layer at the climbing position X1. And, as shown in fig. 3, at a point of time when a predetermined angle is wound after climbing to the existing floor, the climbing part reaches the shooting area of the camera 3. On the other hand, the camera 3 continuously photographs the winding drum 11 from the tangential direction of the main body portion 11a of the winding drum 11, and therefore the climb image shown in fig. 4 is photographed by the camera 3. When the climb image is captured by the camera 3, the control unit 4 recognizes the ascent of the wire X by image processing, and controls the reverse rotation of the winding drum 11 based on the rotation angle of the winding drum 11 with the ascent position X1 of the wire X to the existing floor as a reference (that is, with the ascent position X1 set to 0 °). Further, the camera 3 may perform the image processing, and the control unit 4 may receive the image processing data and perform the reverse movement control of the winding drum 11.
The lower limit of the angle at which the bobbin 11 starts the reverse rotation movement with reference to the rising position X1 of the wire X toward the existing layer is preferably 150 °, and the upper limit thereof is preferably 300 °. If the angle does not satisfy the lower limit, the reverse movement of the winding drum 11 becomes too early, and the layer thickness of the wire material X at the position after the rising is insufficient, and it becomes difficult to smoothly feed the wire material X after winding. On the other hand, if the angle exceeds the upper limit, the thickness of the wire material X at the position after the raising may increase, and it may be difficult to smoothly feed the wire material X after winding. The rotation angle of the winding drum 11 from the point where the wire X overlaps the winding drum 11 to the point where the camera 3 captures an image is stored in the control unit 4 in advance. The control unit 4 controls the winding drum driving mechanism 12 to perform the reverse rotation of the winding drum 11 when the rotation angle of the winding drum 11 with respect to the weight point becomes a predetermined value.
< winding method >
Next, a winding method according to the present invention will be explained. The winding method is a method of arranging wire materials in a plurality of layers on a winding drum while reciprocating the winding drum having a cylindrical body portion and flange portions on both sides thereof in the axial direction, and can be performed by the winding apparatus 1 of fig. 1. The winding method comprises the following steps: an imaging step of imaging the winding drum 11 from the tangential direction of the main body 11 a; and a control step of setting the timing of the reciprocating movement of the winding drum 11 based on the image captured in the imaging step.
(imaging step)
The imaging step is performed by the camera 3. In the imaging step, images of the climbing of the wire X to the existing layer are captured by continuously imaging the winding bobbin 11 in the tangential direction of the main body 11 a.
(control Process)
The control step is performed by the control unit 4. In the control step, the bobbin driving mechanism 12 is controlled so as to reversely move the bobbin 11 with reference to the climb position X1 based on the image of the climb of the wire material X to the existing layer captured in the imaging step. In the control step, it is preferable that the axial movement of the winding drum 11 be stopped when the wire X reaches the vicinity of the inner surface of the flange portion 11b before the winding drum 11 is reversely moved.
The winding method includes an imaging step of imaging the winding drum 11 from the tangential direction of the main body 11a, and can image a climbing image of the wire material X to the existing layer through the imaging step. Further, since the winding method includes the control step of setting the timing of the reciprocating movement of the winding drum 11 based on the image captured in the imaging step, the reciprocating movement of the winding drum can be controlled based on the climb of the wire material X. Therefore, the winding method can easily and reliably suppress the line rising and the line falling of the wire material X as described above.
[ second embodiment ]
< winding device >
The winding device 21 of fig. 5 includes: a movable platform 2; a camera 3 that photographs the winding drum 11 from a tangential direction of the main body 11 a; a wire material alignment mechanism 22 that biases the wire material X toward the flange portion 11b when the wire material X is wound around the winding drum 11; a pair of displacement sensors 23 that measure the axial distance of the flange portion 11b from the wire X; and a control unit 24 for setting the timing of the reciprocating movement of the winding drum 11 based on the image captured by the camera 3 and the interval measured by the pair of displacement sensors 23. The movable platform 2 and the camera 3 in the winding device 21 are the same as those in the winding device 1 of fig. 1, and therefore, the same reference numerals are given thereto and the description thereof will be omitted.
(wire arranging mechanism)
The wire arranging mechanism 22 has a pair of roller units 31. Each roller unit 31 has a shaft portion arranged parallel to the axis of the winding drum 11 and reciprocating in the axial direction thereof; and a roller portion disposed at a tip end of the shaft portion and biasing the wire material X when wound.
The pair of roller units 31 are disposed on the frame 32 via the reciprocating mechanism and the separating mechanism, and are provided so as to be separable from the winding drum 11 and to be movable in the axial direction of the winding drum 11 in a reciprocating manner. Specifically, the wire arranging mechanism 22 includes: a frame 32 as a support table; a moving table 33 disposed on the frame 32 so as to be movable in the axial direction of the winding drum 11; a pair of actuators 34 disposed on a plate portion provided so as to protrude from the movable stage 33 such that the axial direction of the rotary shaft coincides with the moving direction of the movable stage 33; a pair of arm portions 35 connected to rotation shafts of the pair of actuators 34; a pair of roller units 31 attached to the pair of arms 35.
The frame 32 supports the movable table 33 so as to be capable of reciprocating in the axial direction (the left-right direction in the drawing) of the winding drum 11. The frame 32 is provided at both ends thereof with stopper plates for restricting the movement of the movable stage 33.
The moving table 33 reciprocates the pair of roller units 31 in the axial direction of the winding drum 11. The moving mechanism of the moving table 33 may be the same as the winding drum driving mechanism 12 described above.
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 each other with respect to the moving direction. The pair of actuators 34 are disposed so that the axial direction of the rotary shaft coincides with the moving direction of the moving table 33 (the axial direction of the winding drum 11), and the pair of arm portions 35 are provided so as to be movable in a plane perpendicular to the axial direction of the winding drum 11.
The pair of arm portions 35 are configured to be movable in a plane perpendicular to the axial direction of the winding drum 11. Specifically, the pair of arm portions 35 each have a body having one end connected to the actuator 34; and a roller support portion connected to the other end of the main body, wherein the main body and the roller support portion are connected to each other so as to be rotatable in a direction perpendicular to the axial direction of the winding drum 11.
The pair of roller units 31 are configured to be able to press the wire X toward the flange portion 11b of the winding drum 11. The pair of roller units 31 are rotatably supported by the roller support portions via the shaft portions such that the rotation axes are parallel to the axial direction of the winding drum 11 and the roller portions are disposed on the opposite sides of the opposed surfaces of the pair of arm portions 35.
As shown in fig. 6, the pair of roller units 31 includes, as the roller portions: a large diameter roller 36 coaxially disposed at a tip end of the shaft portion, and having a tip end capable of abutting against a side surface of the wire X; the small-diameter roller 37 is coaxially disposed on the tip side of the large-diameter roller 36, and the peripheral surface thereof can abut against the outer periphery of the wire X.
(Displacement pickup)
Each displacement sensor 23 has a light source that can emit laser light; and a detection unit capable of detecting the reflected light of the laser beam emitted from the light source. A pair of displacement sensors 23 are installed in the wire arranging mechanism 22. Specifically, the pair of displacement sensors 23 are attached to the pair of arm portions 35 such that the light emitting direction of the light source coincides with the outer direction (the direction opposite to the facing direction of the pair of arm portions 35) and the axial direction of the shaft portion. Thus, each displacement sensor 23 is configured such that the light source emits laser light with respect to the inner surface of the flange portion 11b, and the detection portion detects the reflected light reflected by the flange portion 11b, thereby enabling measurement of the distance between the displacement sensor 23 and the inner surface of the flange portion 11 b.
(control section)
The control unit 24 may be constituted by a personal computer, a programmable controller, or the like, for example. Similarly to the control unit 4 of the winding device 1 in fig. 1, the control unit 24 controls the winding drum driving mechanism 12 so as to perform the reverse rotation of the winding drum 11 based on the image of the climbing of the wire X on the existing floor when the camera 3 captures the image of the climbing of the wire X on the existing floor. The control unit 24 is configured to stop the reciprocating movement of the winding drum 11 based on the interval measured by the pair of displacement sensors 23. Specifically, the control unit 24 is configured to calculate the distance between the outer side surface of the wire X wound around the winding drum 11 (the side surface on the flange portion 11b side) and the inner surface of the flange portion 11b based on the distance between the displacement sensor 23 and the inner surface of the flange portion 11b measured by the pair of displacement sensors 23, and to stop the movement of the winding drum 11 at a time point when the distance becomes equal to or smaller than a fixed value (for example, a value smaller than the width of the wire X).
A mechanism for measuring the axial distance between the wire material X and the flange portion 11b in the winding device 21 will be described with reference to fig. 6 and 7. First, as shown in fig. 6, in the winding device 21, when the wire X is wound around the one flange portion 11b side of the winding drum 11, one roller unit 31 of the pair of roller units 31 of the wire aligning mechanism 22 in which the small-diameter roller 37 is positioned on the one flange portion 11b side is disposed so as to follow the outer periphery of the wound wire X. 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, thereby measuring the axial distance of the flange portion 11b from the wire material X. As shown in fig. 7, when the distance D between the displacement sensor 23 and the inner surface of the flange portion 11b is equal to or less than a fixed value, the control portion 24 determines that the wire material X has reached the vicinity of the flange portion 11b and stops the movement of the winding drum 11. The winding device 21 may measure the distance between the outer side surface (the side surface on the flange portion 11b side) of the wire X and the inner surface of the flange portion 11b based on the distance D. The winding device 21 can measure the distance D while keeping the axial distance between the displacement sensor 23 and the outer side surface of the wire rod X constant, and calculate the correct distance between the outer side surface of the wire rod X and the inner surface of the flange portion 11b from these values.
When the winding drum 11 is reversely rotated, the one roller unit 31 controls the gap between the wires X by bringing the outer surface of the wire X wound around the winding drum 11 into contact with the circumferential surface of the small-diameter roller 37, bringing the side surface of the large-diameter roller 36 (the surface on the side of the small-diameter roller 37) into contact with the side surface of the wire X, and pressing the wire X toward the flange portion 11b of the winding drum 11.
The winding device 21 includes a displacement sensor 23 that measures the axial distance between the flange portion 11b and the wire material X, and thus can stop the movement of the winding drum 11 based on the axial distance between the wire material X and the flange portion 11 b. Since the winding device 21 stops the movement of the winding drum 11 based on the measured data, rather than stopping the movement of the winding drum by a predetermined program, even when the inner surface of the flange portion 11b has irregularities, the thread lifting and the thread dropping due to the irregularities can be easily suppressed. Therefore, the winding device 21 can control the reciprocating movement more accurately. Further, the winding device 21 is attached to the wire arranging mechanism 22 by the displacement sensor 23, and thus the axial distance between the wire X and the flange portion 11b can be easily and reliably measured.
When the wire material X is wound around the other side of the winding drum 11, the other roller unit 31 of the pair of roller units 31 of the wire material arrangement mechanism 22, in which the small-diameter roller 37 is positioned on the other flange portion 11b side, may be arranged so as to follow the outer periphery of the wound wire material X, and the axial distance of the flange portion 11b from the wire material X may be measured by the displacement sensor 23 attached to the arm portion 35 of the other roller unit 31.
< winding method >
Next, a winding method using the winding device 21 of fig. 5 will be described. The winding method comprises the following steps: a control step of setting the timing of the reciprocating movement of the winding drum 11 based on the image captured by the camera 3 and the interval measured by the pair of displacement sensors 23; and an imaging step of imaging the winding drum 11 from the tangential direction of the main body 11 a. The control step includes a movement stopping step of stopping the movement of the winding drum 11; and a reverse rotation step of reversing the winding drum 11. The winding method is performed in the order of the movement stopping step, the photographing step, and the reverse movement step. The imaging step is the same as the imaging step in the first embodiment, and the reverse movement step is the same as the control step in the first embodiment, and therefore, the description thereof is omitted.
(moving stop step)
The movement stopping step is performed by the pair of displacement sensors 23 and the control unit 24. In the movement stopping 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 portion 11b, thereby measuring the axial distance between the flange portion 11b and the wire material X. In the movement stopping step, when the distance between the pair of displacement sensors 23 and the inner surface of the flange portion 11b is equal to or less than a fixed value, the control portion 24 determines that the wire material X has reached the vicinity of the flange portion 11b and stops the reciprocating movement of the winding drum 11.
Since this winding method includes the movement stopping step, the movement of the winding drum 11 in the axial direction can be easily and reliably stopped at a position where the wire material X reaches the vicinity of the flange portion 11 b. Therefore, this winding method can more accurately suppress the line rising and the line falling of the wire material X (particularly, the line rising and the line falling of the wire material X due to the irregularities of the inner surface of the flange portion 11 b).
[ other embodiments ]
The embodiments disclosed herein are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is not limited to the structure of the above-described embodiments, and is defined by the claims, and is intended to include meanings equivalent to the claims and all modifications within the scope.
For example, even when the winding device includes the displacement sensor, the displacement sensor does not necessarily need to be attached to the wire arranging mechanism. For example, the winding device may be mounted on the guide arm. The wire arranging mechanism in the winding device is not limited to the configuration of the above embodiment. For example, the wire arranging mechanism may include a pair of take-up roll units (roll units that take up the wire toward the flange portion of the winding drum) having small-diameter rolls disposed coaxially at the tip of the shaft portion and having a peripheral surface in contact with the outer periphery of the wire; and a large diameter roller which is coaxially arranged at the front end side of the small diameter roller and the rear end surface of which is abutted with the side surface of the wire rod. In this case, the pair of displacement sensors may be attached to the arm portions of the pair of pull roll units.
The winding device may be configured to shoot or predict a climbing position at which the existing layer of the wire material climbs, and stop the movement of the winding drum at the climbing position.
