Description

[Technical field]

[0001] The present invention relates to an electric wire winding device that winds an electric wire along the outer peripheral surface of a cylindrical rotating body that is rotatably provided around a central axis, and to a rotating body used in the same. [Background technology]

[0002] Conventionally, there has been known an electric wire winding device that winds an electric wire along the outer circumferential surface of a cylindrical rotating body that is rotatably provided around a central axis (see, for example, Patent Document 1). The electric wire winding device described in Patent Document 1 includes six plate-shaped blade members (rib members) that are provided so as to extend from the axial end of the rotating body along a plane perpendicular to the central axis of the rotating body, and a cylindrical holding mechanism that is detachably provided on the outer circumferential surface of the rotating body and holds the electric wire. A user of the electric wire winding device starts winding the electric wire after the electric wire is held by the holding mechanism. Then, after finishing winding the electric wire, the user of the electric wire winding device removes the holding mechanism, thereby being able to pull out the end of the electric wire through the opening where the holding mechanism was located. After removing the holding mechanism, the user of the electric wire winding device can release the electric wire held by the holding mechanism and fold the tips of the blade members so as to move them toward the central axis of the rotating body, thereby being able to remove the wound electric wire wound by the electric wire winding device from the rotating body.

[0003] [Patent Document 1] JP 2018-048022 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the electric wire winding device described in Patent Document 1, in order to remove the wound electric wire wound by the electric wire winding device from the rotating body, a user of the electric wire winding device must perform three tasks: removing the holding mechanism, releasing the electric wire held by the holding mechanism, and folding the blade members. This creates a problem in that the wound electric wire cannot be easily removed from the rotating body.

[0005] An object of the present invention is to provide an electric wire winding device that enables a wound electric wire to be easily removed from a rotating body, and a rotating body used therein. [Means for solving the problem]

[0006] The electric wire winding device of the present invention is an electric wire winding device that winds an electric wire along the outer peripheral surface of a cylindrical rotating body that is freely rotatable around a central axis, and is equipped with a traverser that moves along the axial direction of the rotating body and guides the electric wire to determine the winding position of the electric wire relative to the rotating body, and the rotating body is equipped with at least one plate-shaped bone member that is arranged to extend from the axial end of the rotating body along a plane perpendicular to the central axis of the rotating body, a holding mechanism that is arranged on the rotating body and holds the electric wire, and a switching mechanism that switches between an expanded state in which the bone member is expanded to extend along the plane perpendicular to the central axis of the rotating body and a folded state in which the bone member is folded along the central axis of the rotating body, and the holding mechanism is configured to switch between a holding state that holds the electric wire when the bone member is set to the expanded state by the switching mechanism, and to switch to a released state that releases the electric wire when the bone member is set to the folded state by the switching mechanism.

[0007] With this configuration, the holding mechanism is configured to switch to a holding state in which it holds the electric wire when the frame member is placed in an unfolded state by the switching mechanism, and to switch to a release state in which it releases the electric wire when the frame member is placed in a folded state by the switching mechanism. Therefore, the wound electric wire can be easily removed from the rotating body by simply folding the frame member.

[0008] In the present invention, it is preferable that the rotating body includes a plurality of plate-like members provided along the outer circumferential surface of the rotating body, and the holding mechanism is provided on the inner surface of the plate-like members.

[0009] According to this configuration, the holding mechanism is provided on the inner surface of the plate-shaped member, so that the wound wire can be easily removed from the rotating body without the need to remove the holding mechanism as in the invention described in Patent Document 1.

[0010] Here, when a holding mechanism is provided on the outer peripheral surface of the rotating body as in the invention described in Patent Document 1, the electric wire is wound around the rotating body avoiding the area where the holding mechanism is provided, which results in uneven winding of the electric wire. In contrast, according to the present invention, the holding mechanism is provided on the inner surface of a plate-shaped member that is provided along the outer circumferential surface of the rotating body, thereby making it possible to prevent the wound wire from becoming unevenly aligned, and to make the appearance of the wound wire beautiful.

[0011] In the present invention, the rotating body comprises a cylindrical shaft body arranged coaxially with the central axis of the rotating body, and a cylindrical outer tube arranged coaxially with the central axis of the rotating body and housing the shaft body so that it can move forward and backward along the central axis of the rotating body, and the bone member is attached to the shaft body so that it can rotate freely around a base end on the central axis side of the rotating body, and is attached to the plate-shaped member so that it can rotate freely around a rotating part located slightly toward the tip side of the base end, and it is preferable that the switching mechanism puts the bone member in an expanded state by switching to an advanced state in which the shaft body protrudes from the outer tube, and puts the bone member in a folded state by switching to a retracted state in which the shaft body is housed in the outer tube.

[0012] According to this configuration, the switching mechanism can rotate the bone member about the rotating part so as to move the tip of the bone member away from the central axis of the rotating body to the deployed state by switching to the advanced state in which the shaft body protrudes from the outer tube. Also, the switching mechanism can rotate the bone member about the rotating part so as to move the tip of the bone member closer to the central axis of the rotating body to the folded state by switching to the retracted state in which the shaft body is stored in the outer tube. Therefore, the structure of the switching mechanism can be simplified.

[0013] In the present invention, the holding mechanism comprises a first plate attached to the plate-shaped member, and a second plate attached to the shaft and moving back and forth along the central axis of the rotating body as the shaft moves back and forth, and it is preferable that the second plate cooperates with the first plate to hold the electric wire by switching the shaft to an advanced state by the switching mechanism, and releases the electric wire by switching the shaft to a retracted state by the switching mechanism.

[0014] According to this configuration, the holding mechanism can be constructed by attaching the first plate to the plate-like member and the second plate to the shaft, so that the structure of the holding mechanism can be simplified.

[0015] The rotating body of the present invention is a rotating body used in an electric wire winding device that winds an electric wire along the outer surface of a cylindrical rotating body that is freely rotatable around a central axis, and is equipped with at least one plate-shaped bone member that is arranged to extend from the axial end of the rotating body along a plane perpendicular to the central axis of the rotating body, a holding mechanism that is arranged on the rotating body and holds the electric wire, and a switching mechanism that switches between an expanded state in which the bone member is expanded to extend along the plane perpendicular to the central axis of the rotating body and a folded state in which the bone member is folded along the central axis of the rotating body, and is characterized in that the holding mechanism is configured to switch to a holding state that holds the electric wire when the bone member is set to the expanded state by the switching mechanism, and to switch to a released state that releases the electric wire when the bone member is set to the folded state by the switching mechanism.

[0016] With this configuration, the holding mechanism is configured to switch to a holding state in which it holds the electric wire when the frame member is placed in an unfolded state by the switching mechanism, and to switch to a release state in which it releases the electric wire when the frame member is placed in a folded state by the switching mechanism. Therefore, the wound electric wire can be easily removed from the rotating body by simply folding the frame member. [Brief description of the drawings]

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a top view of a wire winding device according to an embodiment of the present invention. Fig. 2 is a side view of the wire winding device. In Fig. 1 and Fig. 2, the vertically upward direction is defined as the +Z axis direction, and two axes perpendicular to the Z axis are defined as the X and Y axes. The same applies to the following drawings.

[0019] As shown in Figures 1 and 2, the wire winding device 1 includes a rotating body 2 that is rotatable around the X-axis, a rotation drive unit 3 that rotates the rotating body 2, a guide unit 4 that is provided on the -Y-axis direction side of the rotating body 2 and extends along the axial direction (X-axis direction) of the rotating body 2, and a traverser 5 that is placed on the guide unit 4 and moves along the guide unit 4. The electric wire winding device 1 also includes a housing 6 that is configured by combining a box body 61 on which the rotation drive unit 3 is placed and a box body 62 on which the guide unit 4 is placed.

[0020] Fig. 3 is an enlarged view of a side surface of the rotor. Fig. 4 is an enlarged view of a cross section of the rotor. Specifically, Fig. 4 is a view showing a cross section of the rotor 2 cut along an XY plane passing through the central axis of the rotor 2. As shown in Figures 1 to 4, the rotating body 2 includes a cylindrical shaft 21, a first flange portion 22 attached to the -X axis direction side of the shaft 21, a second flange portion 23 attached to the +X axis direction side of the shaft 21, four plate-like members 24 arranged along the outer circumferential surface of the shaft 21, and a retaining mechanism 25 provided on the inner surface of one of the four plate-like members 24.

[0021] The shaft 21 is connected to the rotation drive unit 3. The shaft 21 is driven by the rotation drive unit 3 to rotate around the X-axis. The first flange portion 22 includes four first blade members 22A each having a substantially rectangular plate shape and attached radially on the YZ plane with the shaft 21 at the center. The second flange portion 23 is attached to a position corresponding to the first blade member 22A, and includes four second blade members 23A having a substantially rectangular plate shape attached radially on the YZ plane centered on the shaft 21. Of the four blade members 23A, one blade member 23A includes a handle (not shown) that can rotate the rotor 2 in place of the rotary drive unit 3. In addition, since the first blade member 22A is configured to be freely movable back and forth along the central axis of the rotor 2, the distance between the first blade member 22A and the second blade member 23A is adjustable.

[0022] The plate-like members 24 are provided along the outer circumferential surface of the shaft 21, and are provided between the first blade member 22A and the second blade member 23A. Specifically, the plate-like members 24 are formed into a substantially rectangular plate shape with both ends curved so as to fit along the shaft 21. As a result, the four plate-like members 24 as a whole form an outer circumferential surface in the shape of a cylindrical shaft. Therefore, in this embodiment, the plate-like member 24 functions as the outer circumferential surface of the cylindrical shaft-like rotor 2 that is provided so as to be rotatable about the central axis. 1 does not show first blade member 22A, second blade member 23A, and plate-like member 24 attached in the +Z-axis direction and −Z-axis direction, respectively. In addition, in Fig. 3, second blade member 23A on the +Y-axis direction side is shown by a two-dot chain line, and holding mechanism 25 is shown by a solid line.

[0023] Fig. 5 is an enlarged view of the top surfaces of the plate-like member and the holding mechanism, and Fig. 6 is a further enlarged view of the top surface of the holding mechanism. As shown in Figures 5 and 6, the holding mechanism 25 includes a rectangular fixed plate 251 that extends along the central axis of the rotating body 2 and has one end on the +X axis direction side fixed to the second flange portion 23, a rectangular holding plate 252 that extends from the fixed plate 251 toward the plate-shaped member 24 and is fixed to the other end on the -X axis direction side of the fixed plate 251, and a rectangular adjustment plate 253 that is attached to the plane on the +X axis direction side of the holding plate 252.

[0024] The holding mechanism 25 also includes a rectangular opposing plate 254 that faces the holding plate 252 and the adjustment plate 253, a rectangular support plate 255 that supports the opposing plate 254 so that it can move back and forth along the X-axis direction and is fixed to the plate-shaped member 24, and two springs 256 that are provided between the opposing plate 254 and the support plate 255 and urge the opposing plate 254 toward the holding plate 252 and the adjustment plate 253.

[0025] In this way, the opposing plate 254 is biased toward the holding plate 252 and the adjusting plate 253 by each spring 256, so that the holding mechanism 25 can clamp the electric wire EW between the adjusting plate 253 and the opposing plate 254 by inserting the end of the electric wire EW between the adjusting plate 253 and the opposing plate 254, thereby enabling the electric wire EW to be held.

[0026] Fig. 7 is an enlarged view of the top surface of the plate-like member and the holding mechanism in a state where a large-diameter electric wire is held, and Fig. 8 is a further enlarged view of the top surface of the holding mechanism in a state where a large-diameter electric wire is held. Here, the opposing plate 254 is biased by each spring 256 toward the holding plate 252 and the adjusting plate 253. Therefore, as shown in Figures 7 and 8, the opposing plate 254 moves toward the support plate 255 against the biasing force of each spring 256 (see the arrows in the figures), so that the holding mechanism 25 can clamp the large diameter electric wire EW between the adjusting plate 253 and the opposing plate 254, and can hold the large diameter electric wire EW. The holding mechanism 25 is also capable of holding an electric wire EW having a larger diameter by the holding plate 252 and the opposing plate 254 by removing the adjusting plate 253 attached to the holding plate 252.

[0027] As shown in Figures 4 and 5, shaft 21 comprises a cylindrical shaft body 211 arranged coaxially with the central axis of rotor 2, and a cylindrical outer tube 212 that houses the shaft body and is arranged coaxially with the central axis of rotor 2, and can freely move forward and backward along the central axis of rotor 2. The shaft body 211 supports the above-mentioned second flange portion 23, and is housed in an outer cylinder 212 so as to be slidable along the X-axis direction. The outer cylinder 212 supports the first flange portion 22 described above, and is connected to the rotation drive unit 3.

[0028] Plate member 24 is attached to first flange portion 22 via hinge portion 241 so as to be rotatable around one end on the -X axis direction side. Plate member 24 is also attached to a rotating portion (a portion located slightly toward the tip side from the base end) of second blade member 23A via hinge portion 242 so as to be rotatable around the other end on the +X axis direction side. Second blade member 23A is attached to second flange portion 23 via hinge portion 231 so as to be rotatable around the base end. In other words, the second blade member 23A is attached to the shaft body 211 so as to be freely rotatable around the base end on the central axis side of the rotating body 2, and is attached to the plate-shaped member 24 so as to be freely rotatable around a rotating part located slightly toward the tip side from the base end.

[0029] Fig. 9 is a diagram showing the top surface of the plate member and the holding mechanism in a folded state of the rotor, and Fig. 10 is an enlarged view showing the top surface of the plate member and the holding mechanism in a folded state. As shown in Figures 9 and 10, the rotating body 2 can be folded by moving the shaft main body 211 toward the -X axis direction (see arrow A in Figure 9) so that the tip of the second blade member 23A moves toward the shaft 21. Specifically, by moving shaft body 211 toward the -X-axis direction, second blade member 23A rotates about hinge portion 231 around the Z-axis and is folded with its tip approaching shaft 21 (see arrow B in the figure). In addition, since plate-like member 24 is attached to the rotating portion of second blade member 23A via hinge portion 242, plate-like member 24 rotates about hinge portion 241 around the Z-axis as second blade member 23A rotates (see arrow C in the figure).

[0030] In this way, the rotating body 2 has four second blade members 23A as plate-shaped bone members arranged to extend from the axial end of the rotating body 2 along a plane (YZ plane) perpendicular to the central axis of the rotating body 2. In this embodiment, the rotating body 2 has four second blade members 23A, but the number may be one to three, or may be five or more. In short, it is sufficient that the rotating body 2 has at least one second blade member 23A.

[0031] In addition, the wire winding device 1 is equipped with a switching mechanism which switches the shaft body 211 to an advanced state in which it protrudes from the outer tube 212, thereby setting the second blade member 23A to an expanded state in which it extends along a plane (YZ plane) perpendicular to the central axis of the rotating body 2, and switches the shaft body 211 to a retracted state in which it is stored in the outer tube 212, thereby setting the second blade member 23A to a folded state in which it folds along the central axis of the rotating body 2.

[0032] Here, as mentioned above, the retaining plate 252 and the adjustment plate 253 are connected to the shaft body 211 via the second flange portion 23 and the fixed plate 251, so the retaining mechanism 25 comprises an opposing plate 254 as a first plate attached to the plate-shaped member 24, and the retaining plate 252 and the adjustment plate 253 as second plates attached to the shaft body 211 and moving back and forth along the central axis of the rotating body 2 as the shaft body 211 moves back and forth. The holding plate 252 and the adjustment plate 253 cooperate with the opposing plate 254 to hold the electric wire EW by switching the shaft body 211 to the advanced state using the switching mechanism, and release the electric wire EW by switching the shaft body 211 to the retracted state using the switching mechanism. In other words, the holding mechanism 25 is configured to switch to a holding state in which it holds the electric wire EW when the second blade member 23A is placed in an unfolded state by the switching mechanism, and to switch to a release state in which it releases the electric wire EW when the second blade member 23A is placed in a folded state by the switching mechanism. In this embodiment, the gap between adjustment plate 253 and opposing plate 254 is set to "0" when second blade member 23A is put into the deployed state by the switching mechanism.

[0033] FIG. 11 is a diagram showing the internal structure of the rotation drive unit. As shown in FIG. 11, the rotation drive unit 3 includes two support bases 31 that support the shaft 21 so as to be freely rotatable around a central axis, a timing belt 32 that transmits the power of a motor (not shown) housed in the box body 61 to the outer tube 212 and rotates the outer tube 212 around the central axis, and an air cylinder 33 that moves the shaft main body 211 back and forth along the X-axis direction.

[0034] The air cylinder 33 is connected to the end of the shaft body 211 on the -X axis direction side via a cam follower (not shown), so that the shaft body 211 is capable of rotating around its central axis. Here, since the first blade member 22A and the plate-shaped member 24 are attached to the first flange portion 22, when the motor of the rotation drive unit 3 is driven to rotate the outer tube 212 via the timing belt 32, the first blade member 22A and the plate-shaped member 24 rotate in conjunction with the rotation of the outer tube 212. Furthermore, since the plate-shaped member 24 is attached to the second blade member 23A, and the second blade member 23A is attached to the second flange portion 23, the second blade member 23A and the second flange portion 23 rotate in conjunction with the rotation of the plate-shaped member 24. Since the second flange portion 23 is supported by the shaft body 211, the rotation drive portion 3 can rotate the shaft body 211 and the outer cylinder 212, and can rotate the rotor 2.

[0035] FIG. 12 is a diagram showing the internal structure of the rotation drive unit with the rotor folded up. As described above, the air cylinder 33 can move the shaft body 211 back and forth along the X-axis direction. Therefore, as shown in FIG. 12, the rotating body 2 can be folded by moving the shaft body 211 toward the -X-axis direction using the air cylinder 33 (see arrow A in the figure) so that the tip of the second blade member 23A moves toward the shaft 21. Specifically, by moving shaft body 211 toward the -X axis direction, second blade member 23A rotates about the Z axis and is folded so that its tip approaches shaft 21 (see arrow B in the figure). In addition, plate-like member 24 rotates about the Z axis around hinge portion 241 in conjunction with the rotation of second blade member 23A (see arrow C in the figure). In addition, as shown in FIG. 11, the rotating body 2 can be opened by moving the shaft body 211 toward the +X axis direction using the air cylinder 33, so that the tip of the second blade member 23A moves toward the first blade member 22A.

[0036] As shown in Figures 1 and 2, the guide unit 4 extends along the X-axis direction and includes two cylindrical stroke shafts 41 each provided on either side in the Y-axis direction, a ball screw 42 extends along the X-axis direction and is provided between the stroke shafts 41, and a motor 43 (see Figure 1) that rotates the ball screw 42.

[0037] The traverser 5 is mounted on the stroke shaft 41 so as to be freely slidable along the X-axis direction, and comprises a slider 51 screwed into the ball screw 42, two entrance side traverser rollers 52 provided on the -Y-axis direction side of the slider 51, two exit side traverser rollers 53 provided on the +Y-axis direction side of the slider 51, and a measuring unit 54 provided between the entrance side traverser rollers 52 and the exit side traverser rollers 53.

[0038] The slider 51 can move along the X-axis direction by rotating the ball screw 42 with the motor 43. In other words, the traverser 5 can move along the X-axis direction by rotating the ball screw 42 with the motor 43. The entrance side traverser roller 52 and the exit side traverser roller 53 are attached to the slider 51 so as to be rotatable around the Z axis. The entrance side traverser rollers 52 are attached as a pair on both sides in the Y axis direction. The exit side traverser rollers 53 are attached as a pair on both sides in the Y axis direction. The pair of entrance side traverser rollers 52 and the pair of exit side traverser rollers 53 are configured so that the distance between them can be adjusted.

[0039] The length measuring unit 54 is provided with a plurality of rollers, such as three length measuring rollers arranged on the +Z axis direction side for measuring the length of the electric wire EW fed out from the traverser 5, and three guide rollers arranged on the -Z axis direction side of the length measuring rollers for guiding the electric wire EW by clamping the electric wire EW together with the length measuring rollers. The length measuring unit 54 is provided with an encoder (not shown) attached to the central length measuring roller among the three length measuring rollers, and is capable of calculating the amount of feed of the electric wire EW based on the measurement result of the encoder. The length measuring rollers and the guide rollers are configured so that the interval between them can be adjusted.

[0040] This traverser 5 guides the electric wire EW by passing it from between a pair of entrance side traverser rollers 52 to between a pair of exit side traverser rollers 53, and also between the measuring rollers and guide rollers in the measuring unit 54. As described above, the spacing between the pair of entrance side traverser rollers 52 and the pair of exit side traverser rollers 53, as well as the spacing between the scale rollers and the guide rollers, are configured to be adjustable, so that the traverser 5 can reliably guide the electric wire EW by adjusting the spacing according to the thickness of the electric wire EW. Then, the electric wire EW guided by the traverser 5 has its end held by a holding mechanism 25, so that it is temporarily fixed to the plate-like member 24 of the rotating body 2.

[0041] The electric wire winding device 1 can wind the electric wire EW along the outer circumferential surface of the cylindrical shaft-shaped rotor 2 provided so as to be rotatable around a central axis by rotating the rotor 2 with the rotary drive unit 3. At this time, the traverser 5 moves along the axial direction of the rotating body 2 and guides the electric wire EW to determine the winding position of the electric wire EW relative to the rotating body 2. In addition, the holding mechanism 25 holds the end of the electric wire EW at which winding begins.

[0042] FIG. 13 is a functional block diagram showing a schematic configuration of the electric wire winding device. As described above, the electric wire winding device 1 includes the rotating body 2 and the traverser 5, and further includes, as shown in Fig. 13, a control means 7 for controlling the rotating body 2 via the rotation drive unit 3 and for controlling the traverser 5. The control means 7 is housed inside the housing 6 (see Figs. 1 and 2) described above.

[0043] The control means 7 is configured with a CPU (Central Processing Unit), a memory, etc., and executes information processing according to a predetermined program stored in the memory. The control means 7 includes a reciprocating period setting unit 71, a rotation control unit 72, a reciprocating control unit 73, and a holding control unit 74. The reciprocating period setting unit 71 sets a reciprocating period for moving the traverser 5 back and forth relative to the rotating body 2. Specifically, the reciprocating period setting unit 71 sets the reciprocating period so that the rotation period of the rotating body 2 and half the reciprocating period of the traverser 5 are not synchronized. The rotation control unit 72 rotates the rotating body 2 at a predetermined rotation period using the rotation drive unit 3. Specifically, the rotation control unit 72 rotates the rotating body 2 at a predetermined rotation period input by a user via an operation panel (not shown). The reciprocation control unit 73 rotates the ball screw 42 by the motor 43 to move the traverser 5 along the X-axis direction, thereby causing the traverser 5 to reciprocate at the reciprocation period set by the reciprocation period setting unit 71 . The holding control unit 74 switches the holding mechanism 25 between an open state and a closed state by causing the air cylinder 33 to advance and retreat the shaft body 211 along the X-axis direction.

[0044] The following description will be given by taking as an example a case where the movement width W of the traverser 5 is 90 mm, and the pitch P of the traverser 5 (the movement width of the traverser 5 per rotation of the rotating body 2) is 80 mm. In this case, if the predetermined rotation period is 1 s, then half the reciprocating period of the traverser 5 is 80 / 90 s, so the reciprocating period setting unit 71 sets the reciprocating period so that the rotation period of the rotating body 2 and the half of the reciprocating period of the traverser 5 are not synchronized.

[0045] Fig. 14 is a graph showing the relationship between the outer peripheral surface of the rotor and the electric wire wound around the outer peripheral surface of the rotor. Specifically, Fig. 14 is a graph with the movement width W of the traverser 5 on the vertical axis and the position of the outer peripheral surface of the rotor 2 (rotation angle θ) on the horizontal axis. Fig. 15 is a schematic diagram showing the relationship between the outer peripheral surface of the rotor and the electric wire wound around the outer peripheral surface of the rotor. Specifically, Fig. 15 is a view of the outer peripheral surface of the rotor 2 viewed toward the central axis. In this embodiment, the outer circumferential surface of the rotor 2 is made up of four plate-like members 24, but in FIG. 15, the outer circumferential surface of the rotor 2 is depicted as an ideal circumferential surface.

[0046] In addition, in this embodiment, the holding mechanism 25 that holds the end of the electric wire EW at which winding begins is provided at a central position in the central axis direction of the rotating body 2, so that winding begins from a position where the traverser 5 has a moving width W of 45 mm. However, for the sake of simplicity, Figures 14 and 15 will describe the case where winding begins from a position where the traverser 5 has a moving width W of 0 mm.

[0047] If the rotation of the rotor 2 and the reciprocation of the traverser 5 start simultaneously from the position of the movement width W = 0 mm of the traverser 5, the electric wire EW is wound through a path R1 that reaches a position of the movement width W = 80 mm of the traverser 5 when the rotation angle θ of the rotor 2 reaches 360 degrees, as shown in Figures 14 and 15 (see solid line in Figure 14). During the second rotation, the electric wire EW reaches a position where the traverser 5 has a movement width W = 90 mm when the rotation angle θ of the rotor 2 becomes 45 degrees, then turns around and is wound around through a path R2 which reaches a position where the traverser 5 has a movement width W = 20 when the rotation angle θ of the rotor 2 becomes 360 degrees (720 degrees) (see dotted line in Figure 14).

[0048] During the third rotation, the electric wire EW reaches a position where the movement width W of the traverser 5 is 0 when the rotation angle θ of the rotor 2 is 90 degrees, then turns around and is wound through path R3 which reaches a position where the movement width W of the traverser 5 is 60 when the rotation angle θ of the rotor 2 is 360 degrees (1080 degrees) (see dotted line in Figure 14). During the fourth rotation, the electric wire EW reaches a position where the traverser 5 has a movement width W = 90 when the rotation angle θ of the rotor 2 becomes 135 degrees, then turns around and is wound through path R4 which reaches a position where the traverser 5 has a movement width W = 40 when the rotation angle θ of the rotor 2 becomes 360 degrees (1440 degrees) (see the dotted line in Figure 14). By repeating this process, the electric wire winding device 1 winds up an electric wire EW of a predetermined length around the outer circumferential surface of the rotor 2.

[0049] Here, the reciprocating period setting unit 71 sets the reciprocating period so that the rotation period of the rotating body 2 is not synchronized with half the reciprocating period of the traverser 5, so that the intersection positions X12, 13, 14, 23, 24, 34 of the electric wires EW are dispersed to multiple positions in the circumferential and width directions on the outer circumferential surface of the rotating body 2. Specifically, X12 is the intersection position of the electric wire EW wound in the first rotation and the electric wire EW wound in the second rotation, X13 is the intersection position of the electric wire EW wound in the first rotation and the electric wire EW wound in the third rotation, and X14 is the intersection position of the electric wire EW wound in the first rotation and the electric wire EW wound in the fourth rotation. Furthermore, X23 is the intersection position of the electric wire EW wound in the second rotation and the electric wire EW wound in the third rotation, and X24 is the intersection position of the electric wire EW wound in the second rotation and the electric wire EW wound in the fourth rotation. Furthermore, X34 is the intersection position of the electric wire EW wound in the third rotation and the electric wire EW wound in the fourth rotation.

[0050] In this way, the crossing positions of the wires of the wound wire wound by the wire winding device 1 can be dispersed at multiple positions across the width of the wound wire, so that the wound wire does not become thicker in the radial direction at only certain positions, resulting in a good appearance and making it easier to store in a case, etc.

[0051] FIG. 16 is a flowchart showing a method for controlling the electric wire winding device. When the electric wire EW is wound around the outer circumferential surface of the rotor 2 by the electric wire winding device 1, the control means 7 executes the electric wire winding process of steps S1 to S8 as shown in FIG.

[0052] First, the user passes the electric wire EW through the traverser 5, and then causes the holding control unit 74 to drive the air cylinder 33 via the operation panel (not shown) to fold the tip of the second blade member 23A of the rotating body 2 toward the shaft 21 (see FIG. 12), thereby opening the holding mechanism 25. Then, the user inserts the electric wire EW into the holding mechanism 25 in the open state, and causes the holding control unit 74 to drive the air cylinder 33 via the operation panel (not shown) to open the tip of the second blade member 23A of the rotating body 2 (see FIG. 11), thereby closing the holding mechanism 25. In this way, the user causes the holding mechanism 25 to hold the end of the electric wire EW, thereby temporarily fixing it to the plate-like member 24 of the rotating body 2 (S1: electric wire holding step).

[0053] Next, the user inputs information such as a predetermined rotation period via an operation panel (not shown). The control means 7 stores the information such as the predetermined rotation period input by the user in memory, and sets this as the initial setting (S2: initial setting step).

[0054] Next, the reciprocating period setting unit 71 sets a reciprocating period for moving the traverser 5 back and forth relative to the rotating body 2 (S3: reciprocating period setting step). Here, the reciprocating period setting unit 71 may automatically set the reciprocating period based on a predetermined rotation period input by a user via an operation panel (not shown), or may set the reciprocating period based on information input by a user via an operation panel (not shown). In short, the reciprocating period setting unit 71 may set the reciprocating period so that the rotation period of the rotating body 2 and half the reciprocating period of the traverser 5 are not synchronized. For example, as described above, the reciprocating period setting unit 71 can set the predetermined rotation period to 1 s, and set half the reciprocating period of the traverser 5 to 80 / 90 s.

[0055] After setting the predetermined rotation period and reciprocating period, the rotation control unit 72 rotates the rotor 2 at the predetermined rotation period by the rotation drive unit 3 (S4: rotation control step). In addition, the reciprocating control unit 73 reciprocates the traverser 5 at the reciprocating period set by the reciprocating period setting unit 71 (S5: reciprocating control step). This causes the electric wire winding device 1 to start winding the electric wire EW along the outer circumferential surface of the rotor 2. Here, the timing at which the traverser 5 starts reciprocating at the reciprocating control step S4 is simultaneous with the timing at which the rotor 2 starts rotating at the rotation control step S4.

[0056] In this embodiment, the rotation control step S4 is executed first, and then the reciprocating control step S5 is executed. However, the opposite may be true, that is, the rotation control step S4 is executed after the reciprocating control step S5 is executed, or the rotation control step S4 and the reciprocating control step S5 may be executed simultaneously.

[0057] After starting the rotation of the rotor 2 and the reciprocation of the traverser 5, the control means 7 judges whether or not to end the winding of the electric wire EW (S6: winding end judgment step). In this winding end judgment step S6, the control means 7 measures the length of the electric wire EW wound around the rotor 2 based on the feed amount of the length measuring unit 54. Then, the control means 7 judges to end the winding of the electric wire EW when the length of the electric wire EW wound around the rotor 2 exceeds the length input in advance by the user via an operation panel (not shown), and judges not to end the winding of the electric wire EW when the length does not exceed the length input in advance by the user via an operation panel (not shown).

[0058] When it is determined in the winding end determination step S6 that the winding of the electric wire EW is to be ended, the control means 7 stops the rotation of the rotor 2 and the reciprocation of the traverser 5 (S7: winding end step). When it is determined in the winding completion determination step S6 that the winding of the electric wire EW is not to be completed, the control means 7 executes the winding completion determination step S6 again.

[0059] Then, the user cuts the electric wire EW stretched between the rotating body 2 and the traverser 5 with a cutter (not shown), and then causes the holding control unit 74 to drive the air cylinder 33 via an operation panel (not shown), thereby folding the tip of the second blade member 23A of the rotating body 2 toward the shaft 21 (see FIG. 12), and opening the holding mechanism 25. This allows the user to take out the wound electric wire from the electric wire winding device 1 (S8: electric wire taking out step).

[0060] According to the manufacturing method of this embodiment, the following actions and effects can be achieved. (1) The holding mechanism 25 is configured to switch to a holding state in which it holds the electric wire EW when the second blade member 23A is placed in the unfolded state by the switching mechanism, and to switch to a release state in which it releases the electric wire EW when the second blade member 23A is placed in the folded state by the switching mechanism. Therefore, the wound electric wire can be easily removed from the rotating body 2 by simply folding the second blade member 23A. (2) Since the holding mechanism 25 is provided on the inner surface of the plate-shaped member 24, the wound wire can be easily removed from the rotating body 2 without the need to remove the holding mechanism 25 as in the invention described in Patent Document 1. (3) The holding mechanism 25 is provided on the inner surface of the plate-shaped member 24 that is provided along the outer circumferential surface of the rotating body 2, so that it is possible to prevent the wound wire from becoming uneven, and to make the appearance of the wound wire beautiful.

[0061] (4) By switching the switching mechanism to an advanced state in which the shaft body 211 protrudes from the outer tube 212, the second blade member 23A can be rotated about the rotating part so as to move the tip of the second blade member 23A away from the central axis of the rotating body 2 to the deployed state. In addition, by switching the switching mechanism to a retracted state in which the shaft body 211 is stored in the outer tube 212, the second blade member 23A can be rotated about the rotating part so as to move the tip of the second blade member 23A closer to the central axis of the rotating body 2 to the folded state. Therefore, the structure of the switching mechanism can be simplified. (5) The holding mechanism 25 can be constructed by attaching the opposing plate 254 to the plate-like member 24 and attaching the holding plate 252 and the adjusting plate 253 to the shaft body 211, so that the structure of the holding mechanism 25 can be simplified.

[0062] [Modifications of the embodiment] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of the present invention that can achieve the object of the present invention are included in the present invention. For example, in the above embodiment, the holding mechanism 25 is provided on the inner surface of the plate-shaped member 24, but it may be provided on the outer surface of the plate-shaped member 24 (the outer circumferential surface of the rotating body 2).

[0063] In the above embodiment, the switching mechanism switches the shaft body 211 to an advanced state in which it protrudes from the outer tube 212, thereby setting the second blade member 23A to an unfolded state in which it extends along a plane (YZ plane) perpendicular to the central axis of the rotating body 2, and switches the shaft body 211 to a retracted state in which it is stored in the outer tube 212, thereby setting the second blade member 23A to a folded state in which it folds along the central axis of the rotating body 2. In contrast, the switching mechanism may have any configuration as long as it can switch between an unfolded state in which the second blade member 23A is unfolded so as to extend along a plane perpendicular to the central axis of the rotating body 2, and a folded state in which the second blade member 23A is folded along the central axis of the rotating body 2. For example, the switching mechanism may be configured to be able to switch each bone member individually between an unfolded state and a folded state.

[0064] In the above embodiment, the holding mechanism 25 holds the electric wire EW by using the opposing plate 254 in cooperation with the holding plate 252 and the adjusting plate 253. However, the holding mechanism may have another configuration, such as a clip structure, as long as it can hold the electric wire.

[0065] In the above embodiment, the holding mechanism 25 is mechanically configured to be switched to a holding state in which the electric wire EW is held when the second blade member 23A is in the unfolded state by the switching mechanism, and to be switched to a release state in which the electric wire EW is released when the second blade member 23A is in the folded state by the switching mechanism, by attaching the opposing plate 254 to the plate-like member 24 and attaching the holding plate 252 and the adjustment plate 253 to the shaft body 211. In contrast, the holding mechanism may be configured in any manner as long as it is configured to be switched to a holding state in which the electric wire is held when the bone member is in the unfolded state by the switching mechanism, and to be switched to a release state in which the electric wire is released when the bone member is in the folded state by the switching mechanism. For example, the holding mechanism may be configured to be switched to a holding state or a release state by being electrically controlled based on each state of the bone member.

[0066] In the above embodiment, the rotating body 2 includes a shaft body 211 and an outer cylinder 212, the shaft body 211 is connected to the air cylinder 33 via a cam follower, and the outer cylinder 212 is connected to the motor via a timing belt 32. In other words, the rotating body 2 is fixed to the rotation drive unit 3. In contrast, the rotating body 2 may be detachably attached to the rotation drive unit 3. Specifically, for example, the rotating body may include a hollow cylindrical first cylindrical body (inner cylinder) and a hollow cylindrical second cylindrical body (outer cylinder) having an inner peripheral surface that slides with the outer peripheral surface of the first cylindrical body, a key groove may be formed on the inner peripheral surface of the first cylindrical body, the output shaft of the motor may be inserted inside the first cylindrical body, and the motor and the first cylindrical body may be detachably attached via a key. When the rotating body is configured in this way, the first cylindrical body is rotated by the motor, so there is no need to connect the second cylindrical body to the motor.

[0067] Furthermore, as described above, when the rotating body is formed by a first tubular body and a second tubular body, the switching mechanism may be configured to switch the second tubular body to an advanced state in which it advances toward the tip of the first tubular body, thereby achieving an expanded state in which the bone member extends along a plane perpendicular to the central axis of the rotating body, and to switch the second tubular body to a retracted state in which it retracts toward the base end of the first tubular body, thereby achieving a folded state in which the bone member is folded along the central axis of the rotating body.

[0068] Also, as described above, when a key groove is formed on the inner peripheral surface of the first cylindrical body, the output shaft of the motor is inserted into the inside of the first cylindrical body, and the motor and the first cylindrical body are detachably attached via a key, the switching mechanism may be configured to be able to switch the rotating body between the unfolded state and the folded state by gripping and moving the bone member. When the rotating body is configured in this way, the rotating body can be manually switched between the unfolded state and the folded state, so there is no need to connect the first cylindrical body and the second cylindrical body to the air cylinder.
