  In the case of the wire winding device described in each of the above patent documents, a relatively high ordinary wire having a proof stress value of about 120 MPa can be wound without any problem because the tension applied to the wire during winding can be sufficiently increased. be able to.

  On the other hand, in recent years, in the field of solar cells, a wire rod having a proof stress value of 90 MPa or less is required particularly for an interconnector that connects solar cells. In order to avoid an increase in the proof stress of the rectangular wire, it was necessary to keep the tension at the time of winding and conveying the flat wire low, such as conveying and winding with a small tension of 3N or less.

  However, due to the shape of the flat wire and the low tension winding as described above, the flat wire is separated from the bobbin jaw by more than the set value immediately before the bobbin jaw provided at the end of the bobbin. There is a problem that the flat wire is wound in a state where a gap into which the flat wire can enter is generated between the wire and the bobbin jaw, and the flat wire falls into the gap, that is, the flat wire slides down (for example, Patent Documents). 2).

  In this example, as shown in FIG. 6B, the outermost flat wire W of the third layer from the bottom slides into the gap G between the flat wire W of the second layer and the adjacent jaw B1 from the bottom. There is a problem that falls. Here, FIG. 6B shows a case where the inflow angle D of the flat wire W of the first winding of the second layer is switched by the reversal movement by the traverse T to the inner body of the winding bobbin B of the flat wire W. Due to the circumstances described above, the ability to wind the flat wire W is weakened because the flat wire W has to be wound with a small tension, and the flat wire W slides in the direction away from the adjacent jaw B1 to move the jaw. An example in which the separation distance between B1 and the flat wire W is increased is shown.

  For this reason, if a gap is created between the lower flat wire and the bobbin jaw, and the upper flat wire slides into the gap, the flat wire that has slipped may be bent or twisted. There is a problem that it is treated as a defective product.

  In order to solve this problem, for example, it is conceivable to arrange a guide member on the winding bobbin side at the time of winding the wire to bias the wire to adjust the separation distance between the lower jaw and the wire. (For example, see Patent Document 3).

  However, according to this method, as shown in FIG. 6 (a), although the problem of the sliding-down of the flat wire into the gap can be solved, the flat wire is guided by the guide member throughout the winding process. An excessively strong force is applied to the flat wire due to the frictional force when the flat wire comes into contact with the guide member, and the yield strength value of the flat wire is increased. Moreover, there is a problem that the surface plating of the flat wire is damaged by receiving a frictional force when the flat wire comes into contact with the guide member.

  For this reason, in the case of a flat wire such as a flat-plated wire having a 0.2% proof stress value of 90 MPa or less, the low proof stress value can be maintained and the plating applied to the surface of the flat wire is not damaged. There is a need for a winding device that can perform aligned winding in a state. That is, a winding that does not slip into the gap between the lower rectangular wire and the adjacent jaw and suppresses an increase in the yield strength of the rectangular wire after winding as much as possible compared to the yield strength of the rectangular wire before winding. A take-off device is required.

  An object of the present invention is to provide a winding device for a rectangular wire that can prevent slip-down at the time of winding a rectangular wire having a low proof stress, and can suppress an increase in the proof strength after winding the rectangular wire as much as possible. There is to do.

  The flat wire winding device of the present invention includes an inner cylinder that can be wound by laminating a rectangular wire on the outer periphery, and jaws that are provided at both ends of the inner cylinder and formed by a difference in outer diameter between the inner cylinder and the inner cylinder. A winding bobbin comprising an end plate, a guide roll for guiding the rectangular wire supplied from the supply side to the inner body, and the winding bobbin being rotatable in the circumferential direction of the winding bobbin And a traverse that is held so as to be reciprocally movable in the axial direction and cooperates with the winding bobbin, and a flat wire rod that is wound around the inner body by rotating the winding bobbin by driving the traverse and winding the laminated bobbin. A winding means for winding the rectangular wire guided by the inner cylinder around the inner cylinder, a detection unit provided on the traverse and reciprocating with the traverse, and the detection Detecting the position of the part and generating a position detection signal And a control means for calculating a distance between the outermost flat wire wound around the inner drum and the jaw based on the position detection signal and generating a drive control signal, respectively. In the take-up device, at least one guide member capable of guiding the rectangular wire positioned between the guide roll and the inner body of the take-up bobbin to the jaw side, and a position where the guide member is lowered from a predetermined initial position. Expansion and contraction means for moving the guide wire up and down, and an outermost portion in which a rectangular wire positioned between the guide roll and the inner cylinder of the winding bobbin is wound around the inner cylinder by the drive control signal. It is characterized in that the distance between the flat wire at the outermost end and the jaw on the jaw side is guided within a predetermined distance on the side of the jaw close to the flat wire at the end.

  In the flat wire winding device of the present invention, the guide member is composed of two guide members juxtaposed, and the expansion / contraction means lowers the one guide member to the lowered position by the drive control signal. In this way, the flat wire positioned between the guide roll and the inner cylinder of the take-up bobbin is brought close to the outermost flat wire wound around the inner cylinder by the lowered guide member. The distance between the flat wire at the outermost end and the jaw on the jaw side is guided within a predetermined distance.

  In the flat wire winding device of the present invention, the guide member is lowered by the drive control signal when the outermost flat wire wound in a laminated state becomes the final winding in the layer. The flat wire positioned between the guide roll and the inner cylinder of the take-up bobbin is lowered to the position on the jaw side adjacent to the outermost flat wire wound around the inner cylinder, and the outermost The distance between the flat wire at the end and the jaw on the jaw side is guided within a predetermined distance, and the lowered guide member is raised to the initial position after a predetermined time has elapsed. .

  The rectangular wire winding device of the present invention is also generated by calculating the distance between the outermost rectangular wire wound around the inner trunk and one or the other jaw based on the position detection signal. In response to the drive control signal, the guide member facing the one or the other jaw is lowered to the lowered position, and a flat wire positioned between the guide roll and the inner cylinder of the winding bobbin is moved to the inner cylinder. A distance between the outermost flat wire and the jaw on the jaw side is guided within a predetermined distance. It is said.

  In the flat wire winding device according to the present invention, the distance between the flat wire at the outermost end and the jaw portion on the jaw side is a distance corresponding to a half of the width of the flat wire. It is a feature.

  Since the flat wire winding device of the present invention is configured as described above, it prevents slipping off when winding a flat wire with a low yield strength, and suppresses an increase in the yield strength after winding the flat wire as much as possible. It is possible to provide a winding device for a rectangular wire that can be used.

  Embodiments of the present invention will be described below with reference to the drawings. Hereinafter, the rectangular wire described in the present embodiment will be described by taking a low-strength rectangular plating wire as an example, but this embodiment can be applied to a rectangular wire other than the low-strength rectangular plating.

  The configuration of the rectangular wire winding device of this embodiment will be described below with reference to FIGS. As shown in FIGS. 1 and 2, the winding device 100 according to the present embodiment is provided with an inner cylinder B1 that can be wound by laminating a rectangular wire W on the outer periphery, and the inner cylinder B1 provided at both ends of the inner cylinder B1. A guide for guiding a winding bobbin B composed of end plates B2 and B3 formed with jaws B4 and B5 by an outer diameter difference from B1 and a rectangular wire W supplied from the supply side to the inner cylinder B1. A roll R, at least one guide member 1 and 2 capable of guiding a flat wire W positioned between the guide roll R and the inner body B1 of the winding bobbin B toward the jaws B4 and B5, and a winding bobbin B Of the winding bobbin B so as to be rotatable in the circumferential direction and reciprocally movable in the axial direction and to cooperate with the winding bobbin B, and to drive the traverse T to rotate and rotate the winding bobbin B. This layer of flat wire W wound around the inner body B1 In each of the final windings, the winding means 10 for winding the rectangular wire W guided by the inner cylinder B1 around the inner cylinder B1 and the laminated state of the rectangular wires W wound and laminated The separating means 5 that moves the guide members 1 and 2 to the outside of the take-up bobbin B following the above, and the expansion / contraction means 4 that moves the guide members 1 and 2 up and down between a predetermined initial position S and a lowered position L; Is provided. The configuration of the winding device 100 will be described in detail below.

  The inner cylinder B1 of the winding bobbin B has a bobbin width B6, and is composed of end plates B2 and B3 in which jaw parts B4 and B5 are formed by the outer diameter difference from the inner cylinder B1, respectively. The origin of the take-up bobbin B is set at the center position of the bobbin width B6. When the flat wire W is wound around the take-up bobbin B, the above-mentioned is provided via the guide roll R. The winding bobbin B starts rewinding in the axial direction of the traverse T while rotating in cooperation with the traverse T to wind up the rectangular wire W.

  The guide roll R is rotatably attached and fixed to a supply means on the supply side of a flat wire W (not shown). Further, at least one guide member capable of guiding the flat wire W positioned between the guide roll R and the inner body B1 of the winding bobbin B toward the jaws B4 and B5 is provided. In this embodiment, the guide member is composed of two guide members 1 and 2 as will be described later.

  In addition, the traverse T is horizontally installed on the winding means 10 so as to be rotatable and reciprocable in the axial direction of the traverse T, and is wound and reciprocated in the axial direction by a traverse rotation motor 22 which is a drive mechanism.

  In the winding device 100 of the present embodiment, the winding start end of the flat wire W is brought into contact with one of the jaws B4 and B5 of the winding bobbin B, and a control signal output from the control device 14 described later is used. The traverse rotation motor 22, the slide table moving motor (not shown), and the take-up roll are started to rotate.

  As a result, the flat wire W is supplied from the supply side, and the flat wire W is guided to the winding bobbin B through the guide roll R, and the winding bobbin B is rotated at a constant speed via the traverse T by the traverse rotating motor 22. Then, winding the rectangular wire W around the inner cylinder B1 is performed.

  At this time, the tension of the rectangular wire W is such that the rotational speed of the take-up bobbin B and the rotational speed of the take-up roll not shown in the figure are kept constant by moving the dancer roll not shown in the figure up and down. It is adjusted to become. And the tension | tensile_strength applied to the flat wire W can be confirmed by using a tensiometer with respect to the flat wire W from the fixed pulley (not shown) directed between the dancer roll and the guide roll to the guide roll R. Yes.

  Moreover, it is desirable that the tension of the rectangular wire W when being conveyed from the supply side is 3N or less. This is because when the tension exceeding 3 N is applied to the flat wire, the proof stress value of the flat wire W after winding of the flat wire may be increased. On the other hand, in consideration of the production speed of the low yield strength rectangular wire W, it is desirable that the tension during the conveyance of the rectangular wire W is 1 N or more.

  Further, the proof stress value of the rectangular wire W of the present embodiment is desirably 30 MPa or more and 90 MPa or less. This is because there is usually no problem such that the proof stress value rises even if a normal tension is applied during conveyance from the supply means for the wire W exceeding 90 MPa, and the current manufacturing process is considered for the wire rod less than 30 MPa. This is because commercialization is difficult.

  The separation means 5 includes a connection plate 6, a motor 8 attached to the above-mentioned unillustrated machine body, and a connection rod 7 that reciprocates in the vertical direction in cooperation with the gear of the motor 8.

  This separating means 5 receives a signal sent by a measuring device (not shown) that records the amount of the rectangular wire W wound up by measuring the number of rotations of the take-up roll, and is connected. The expansion / contraction means 4 is gradually moved outward of the winding bobbin B through the rod 7 and the connection plate 6 at a set distance. Thereby, the contact between the guide member 1 and the flat wire W wound around the winding bobbin B can be prevented.

  The expansion / contraction means 4 is guided by the position detection signals 13A and 13B of the jaw sensors 12A and 12B that detect the axial position of the take-up bobbin B, that is, the distance in the axial direction of the traverse T by the detection unit 11 described later. Are reciprocated in the vertical direction. That is, the expansion / contraction means 4 of this embodiment is a lifting / lowering means for the guide member 1.

  At this time, the reciprocating movement of the guide member 1 by the expansion / contraction means 4 is performed by reciprocating the arms 1A, 2A by the pneumatic means 4A, 4B by the air cylinder. The expansion / contraction means 4 of this embodiment may use a mechanism other than the pneumatic means, that is, a mechanism using a hydraulic means or the like.

  Further, the expansion / contraction means 4 receives drive control signals 15A and 15B from the control device 14 to be described later, and the air cylinder located at a position away from the jaws B4 and B5 is filled with air, and the arm 1A or 2A of the air cylinder is filled. At the same time, the guide member 1 or 2 is lowered.

  In this embodiment, the expansion / contraction means 4 receives the drive control signals 15A and 15B from the control device 14, and the air cylinders 4A and 4B located at the same positions as the jaws B4 and B5 are filled with air. The guide member 1 or 2 may be lowered together with the arm 1A or 2A.

  The winding device 100 according to the present embodiment is also provided with a detection unit 11 that is provided in the traverse T and reciprocates with the traverse T, and a detection unit that detects the position of the detection unit 11 and generates position detection signals 13A and 13B. 12 and based on the position detection signals 13A and 13B, the distance between the outermost flat wire W wound around the inner body B1 and the jaws B4 and B5 is calculated to generate drive control signals 15A and 15B, respectively. And a control device 14 for performing the operation. The configuration of the winding device 100 will be described in detail below.

  The traverse T is installed on the fixed base 20 via the slide table 21, and the detection unit 11 is attached to the traverse T. The slide table 21 is provided so as to slide left and right on the fixed base 20. By this movement of the slide table 21, the rectangular wire W is wound once around the inner cylinder B1 of the winding bobbin B at a traverse pitch according to the moving speed of the slide table 21.

  The fixed base 20 is provided with a detection sensor composed of jaw sensors 12A and 12B, which are detection means 12, and an origin sensor 12C. Thereby, when the winding of the first layer of the rectangular wire W to be described later is finished, the position of the detection unit 11 fixed under the slide table 21 is set to the jaw sensor 12A or 12B provided on the fixed base 20 side. Is detected. At this time, the position of the detection unit 11 corresponds to the distance between the rectangular wire W at the outermost end wound around the inner trunk B1 and the jaws B4 and B5 due to the configuration with the traverse T described above. . The position of the detection unit 11 is detected by the jaw sensors 12A and 12B, and position detection signals 13A and 13B are output to the control device 14 from the jaw sensors 12A and 12B.

  Based on the position detection signals 13A and 13B, the control device 14 calculates the distance between the outermost rectangular wire W wound around the inner cylinder B1 and the jaws B4 and B5 to calculate the drive control signals 15A and 15B. And the signals 15A and 15B are output to the separation mechanism 5 and the expansion / contraction means 4. Thus, the separation mechanism 5 and the expansion / contraction means 4 are driven by the drive control signal as described above.

  Further, the control device 14 inputs a distance between the two jaw portions B4 and B5 of the winding bobbin B, a width of the flat wire W, and a gap G between the flat wire W and the jaw portions B4 and B5. An input device (for example, a touch panel for data input) is provided, and the inter-line pitch of the rectangular wire W is determined by calculation in the control device 14. When the line pitch is determined, the number of windings of the flat wire W that can be wound on the first layer of the inner body B1 of the winding bobbin B is determined. This also makes it possible to calculate the distance between the outermost rectangular wire W wound around the inner cylinder B1 and the jaws B4 and B5.

  Then, the control device 14 outputs a signal corresponding to the line pitch to a slide table moving motor (not shown), whereby the slide table to which the traverse T is fixed is moved at a predetermined speed. ing.

  In the winding device 100 of the present embodiment, the guide member further includes two guide members 1 and 2 arranged side by side, and the expansion / contraction means 4 descends one guide member 1 or 2 by the drive control signals 15A and 15B. The rectangular wire W positioned between the guide roll R and the inner drum B1 of the take-up bobbin B is wound around the inner drum B1 by the lowered guide member 1 or 2 being lowered to the position L. The distance between the outermost flat wire W adjacent to the outermost flat wire W and the outermost flat wire W and the above-mentioned jaw B4 or B5 is within a predetermined distance. Guided. The configuration of the winding device 100 will be described in detail below.

  The guide member of the winding device 100 of the present embodiment is provided with two guide members 1 and 2 juxtaposed. The positional relationship between the flat wire W and the guide members 1 and 2 when the flat wire W is wound is such that the guide member 1 or 2 is in contact with the side surface of the flat wire W being wound, as shown in FIG. The guide members 1 and 2 can be guided by being urged against the flat wire W.

  The guide members 1 and 2 are attached to the ends of the arms 1A and 2A provided in the air cylinders 4A and 4B as the expansion / contraction means 4, respectively. In the present embodiment, for example, with respect to the guidance by urging the flat wire W of the first winding of the first layer to the left jaw B5 side, the right guide member 1 performs this and the right side The left guide member 2 performs the guidance by urging to the jaw B4 side.

  Further, in the present embodiment, for example, with respect to guidance by urging the flat wire W of the first winding of the first layer, the left guide member 2 performs this when it is directed to the left jaw B5 side. For the guidance by urging to the right jaw B4 side, the right guide member 1 may perform this. Further, the number of guide members is not limited to two, and one guide member can be used.

  It is desirable that the guide members 1 and 2 are formed in a cylindrical shape that has little frictional force even when coming into contact with the flat wire W, and that is difficult to cut the plating on the surface of the flat wire W. Moreover, it is desirable that the tip portions of the guide members 1 and 2 are tapered. According to this, even if the flat wire W is sandwiched between the guide member 1 and the jaws B4 and B5, for example, the flat wire W is escaped to the external space and thus does not deform.

  Hereinafter, an operation example of the guide members 1 and 2 in the winding device 100 of the present embodiment will be described with reference to FIGS.

  When the rectangular wire W wound around the inner body B1 is not positioned at both jaws B4 and B5 of the winding bobbin B, the guide members 1 and 2 attached to the expansion / contraction means 4 are wound from the guide roll R. It is arranged at an initial position S on the flat wire W between the take-up bobbins B.

  As shown in FIGS. 1A and 2, the flat wire W is wound up to the right jaw B4 of the winding bobbin B, that is, the flat wire W at the outermost end is applied to the left jaw B5. When the final winding is performed, the control device 14 receives the position detection signal 13B of the jaw sensor 12B that detects the position of the detection unit 11, and generates a drive control signal 15B based on the position detection signal 13B.

  By this drive control signal 15B, the expansion / contraction means 4 is already wound around the left guide member 2 attached to the expansion / contraction means 4 from the guide roll R to the winding bobbin B in the normal winding state. The rectangular wire at the outermost end is moved down to the nearest position L not in contact with the flat wire W, and the flat wire W is wound around the right jaw B4 of the take-up bobbin B by a predetermined value or more, that is, wound around the inner body B1. The distance between W and jaw B4 is guided within a predetermined distance.

  Here, as the distance between the flat wire W at the outermost end and the jaw part B4, for example, a distance that is a half of the width of the flat wire W is used, and the winding device 100 of this embodiment uses this value. Although other values are used, other values can be used as set values. Further, in the winding device 100 of the present embodiment, the nearest position L is a lowered position with respect to the initial position S. Hereinafter, the nearest position L is also referred to as a lowered position L.

  Further, as shown in FIG. 1B, when the flat wire W is to be wound up to the left jaw B5 of the winding bobbin B, that is, the flat wire W at the outermost end is finally wound around the left jaw B4. When receiving the position detection signal 13A of the jaw sensor 12A that detects the position of the detection unit 11, the control device 14 generates a drive control signal 15A based on the position detection signal 13A.

  By this drive control signal 15A, the expansion / contraction means 4 is already wound around the right guide member 1 attached to the expansion / contraction means 4 from the guide roll R to the winding bobbin B in the normal winding state. The flat wire W is lowered to a lowered position L not in contact with the flat wire W, and the flat wire W is wound from the left jaw B5 of the winding bobbin B to a predetermined set value or more, that is, the width of the flat wire W and the inner body B1. The distance between the flat wire W at the outermost end and the jaw B5 is guided within a predetermined distance.

  The expansion / contraction means 4 also raises the guide member 1 or 2 to the initial position S, for example, after 60 seconds after receiving a signal from the sensors 12A and 12B that detect the position of the traverse T, for example, 60 seconds later. Move back. In the present embodiment, other values can be set for the predetermined time.

  Further, in the present embodiment, when winding up to the jaws B4 and B5 of the winding bobbin B, that is, when the rectangular wire W at the outermost end performs the final winding around the jaws B4 and B5. In addition, either of the guide members 1 or 2 can be moved downward to the lowered position L by the drive control signals 15A and 15B, and the rectangular wire W can be moved to the jaw portion of the winding bobbin B as described above. It is possible to guide the distance between the outermost flat wire W wound around the inner cylinder B1 and the jaws B4 and B5 within a predetermined distance from B4 and B5 by a predetermined set value or more.

  Here, the reason why the descending position of the guide members 1 and 2 is set to the nearest position L not in contact with the already wound rectangular wire W is to apply a frictional force to the already wound rectangular wire W. This is to suppress the increase in the yield strength of the flat wire W as much as possible.

  In addition, since the guide members 1 and 2 are cylindrical, when the flat wire W comes into contact with the guide members 1 and 2, for example, even if the flat wire W is a low yield strength plated wire having a yield strength of 47 to 50 MPa, Since the proof stress value obtained by measuring the flat wire W is 47 to 50 MPa, it is estimated that the contact friction force of the flat wire W is small.

  That is, according to the winding device 100 of the embodiment of the present invention, there is no occurrence of surface scratches on the rectangular wire W due to the increase in the proof stress value of the rectangular wire W by the guide members 1 and 2 and the large frictional force. It is possible to perform a winding operation of a good flat wire W onto the winding bobbin B.

  Hereafter, the operation | movement procedure of the winding method of the flat wire W using the winding apparatus 100 which is an Example of this invention is demonstrated. As for the following winding method, the right guide member 1 performs the guide to the jaw part side of the flat wire W at the time of the final winding. In the case of the jaw B4 side, a configuration in which the left guide member 2 performs this will be described as an example.

  First, the distance between the two jaws B4, B5 of the winding bobbin B, the width of the flat wire W, and the gap between the flat wire W and the jaws B4, B5 are input from a manual input device (not shown), and the control device 14 is used to determine the line pitch of the flat wire W.

  Next, the winding start end of the flat wire W is brought into contact with one jaw B1 of the winding bobbin B, and a signal is output from the control device 14, and the traverse rotary motor 22 and a slide table moving motor (not shown) are output based on this signal. And the rotation drive of the take-up roll is started.

  Accordingly, the flat wire W is supplied from the supply side, and the flat wire W is supplied to the winding bobbin B through the guide roll R, and the winding bobbin B is fixed in cooperation with the traverse T by the traverse rotating motor 22. The flat wire W is wound around the inner cylinder B1 by rotating at a speed.

  At this time, the tension applied to the flat wire W is measured so that the flat wire W from the fixed pulley (not shown) to the guide roll R can be confirmed using a tension meter (not shown).

  Further, a signal corresponding to the line pitch is output from the control device 14, and a slide table moving motor (not shown) drives the slide table 21 based on this signal to move the traverse T in the axial direction at a predetermined speed. . Thereby, the flat wire W is wound once around the inner cylinder B1 of the winding bobbin B at a traverse pitch according to the moving speed of the slide table 21.

  The above operation is continuously repeated by a predetermined number of windings (for example, 8 times), and the rectangular wire W is formed on the outer periphery of the inner body B1 of the winding bobbin so that the input gap is generated between the other jaw B5. Is wound at a predetermined winding pitch, and the winding of the first layer is completed.

  Here, when the winding of the first layer is finished, that is, when the outermost flat wire W is wound around the left jaw B5, the position of the detection unit 11 fixed below the slide table 21 is determined. The jaw sensor 12A provided on the fixed base 20 side detects, and a position detection signal 13A generated based on the detection of the jaw sensor 12A is output to the control device 14, and further controlled based on the position detection signal 13A. The distance between the flat wire W at the outermost end around which the device 14 is wound around the inner cylinder B1 and the jaw B5 is calculated, and a drive control signal 15A is output from the control device 14. Then, by the drive control signal 15A, the guide member 2 is lowered from the initial position S to the lowered position L toward the inner body B4 of the winding bobbin B by the expansion / contraction means 4.

  In addition, by the drive control signal 15A, a slide table moving motor (not shown) reverses its rotation and 1 of the rectangular wire W wound around the inner cylinder B1 of the winding bobbin B with the above-described predetermined winding pitch. The first winding of the rectangular wire W of the second layer that has gone up from the first layer is performed. At this time, since the guide member 1 is in the lowered position L, the flat wire wound with the first layer of the second layer is wound around the jaw portion of the winding bobbin adjacent to a predetermined distance, that is, the inner cylinder B1. Further, the distance between the flat wire W at the outermost end and the jaw B5 can be guided within a predetermined distance.

  Next, after a predetermined time has elapsed after the control device 14 receives the position detection signal 13B of the jaw sensor 12B that detects the position of the detection unit 11 (for example, after 60 seconds), the expansion / contraction means 2 is moved to the guide member 1, The operation of moving 2 up to the initial position S and returning it is started.

  Next, the flat wire W of the last roll of the second layer is wound around the winding bobbin B, and the winding of the flat wire W of the second layer is completed, and the flat wire W at the outermost end is the right jaw B4. At the time of the final winding, the position of the detection unit 11 fixed below the slide table 12 is detected by the jaw sensor 12B provided on the fixed base 20, and the position detection signal 13B of the jaw sensor 12B is detected. The control device 14 receives the control device 14 and calculates the distance between the outermost flat wire W wound around the inner cylinder B1 and the jaw B4, and the control device 14 outputs a drive control signal 15B. In response to the drive control signal 15B, the expansion / contraction means 4 fills the cylinder 4A with air, and the guide member 1 of the air cylinder 4A starts to descend. That is, the guide member 1 of the expansion / contraction means 4 is lowered from the initial position S to the lowered position L toward the inner body B1 of the winding bobbin B.

  Next, a slide table moving motor (not shown) reverses its rotation by a drive control signal 15B of the control device 14, and rises from the second layer with the above-mentioned predetermined winding pitch, and the first flat angle of the third layer. The wire W is wound around the winding bobbin B. At this time, since the guide member 1 is in the lowered position, the first winding flat wire W of the third layer, which has risen, is urged and guided toward the adjacent jaw B5 side, and the first winding It is possible to guide the distance between the flat wire W and the jaw B4 at the outermost end wound around the inner body B1 by a predetermined distance or more from the jaw B5 within the predetermined distance.

  Then, after a predetermined time (for example, 60 seconds) has elapsed since the control device 14 received the position detection signal of the jaw sensor 12B that detects the position of the detection unit 11, the expansion / contraction means 4 raises the guide member 1 to the initial position. Start moving and returning.

  As described above, when the winding of the second layer is completed, the above-described operation is repeated in the same manner as described above until the winding of the flat wire W is completed.

  In the above, in the present embodiment, the operation of the guide members 1 and 2 to move upward and return to the initial position S starts 60 seconds after receiving the position detection signals 13A and 13B of the jaw sensors 12A and 12B. This is after the rectangular wire W has rotated about the inner cylinder B1 by about 8 rotations, and the guide member 1 remains at the lowered position L until then.

  With respect to this, in this embodiment, the rectangular wire W of the first volume that has been raised by the guide members 1 and 2 is guided to the side of the jaws B4 and B5 that are close to the first wire, thereby guiding the rectangular wire. Since the flat wire W generated when the inflow angle of the winding bobbin B with respect to the inner body B1 is switched can be prevented from sliding away from the adjacent jaws B4 and B5, the guide member can be stopped as described above. Even if 1 and 2 are stopped at the lowered position L, there is no problem in winding the flat wire W in a normal state.

  In the winding device 100 of the present embodiment, the guide members 1 and 2 are further urged and guided by the first winding flat wire W, which has been raised, and then raised from the lowered position L to the initial position S by the expansion / contraction means 4. Since it is made to move, the contact of the guide members 1 and 2 to the flat wire W after the second roll in the layer in which the flat wire W is in the middle of winding is reliably prevented, and the 0.2% proof stress of the flat wire is obtained. An increase in the value is suppressed as much as possible, and the surface of the flat wire W is not damaged.

  In addition, as described above, the winding device 100 according to the present embodiment returns to the initial state S when the guide members 1 and 2 wind the flat wire W to a predetermined number of turns (for example, the eighth). Since it does not contact the wire W, the 0.2% proof stress value of the flat wire W does not increase due to the frictional force caused by the contact with the guide members 1 and 2. In addition, careless damage to the surface plating of the flat wire W can be prevented.

  Further, when the flat wire W is wound around the bobbin from the lower layer to the upper layer, the flat wire W is not separated from the bobbin jaw by the guide member beyond the predetermined value as described above. It does not slip into the gaps of the wire and does not affect the proof stress value and surface plating of the flat wire.

  Therefore, according to the flat wire winding device of the present embodiment, since it is configured as described above, it prevents slipping off when winding the flat wire, and increases the yield strength after winding the flat wire as much as possible. A flat wire winding device that can be suppressed can be provided.

  Moreover, the guide member used for the winding device in the present embodiment may be configured as shown in FIG. Another application example of the guide member described below shows one guide member 1, and the other guide member 2 can be configured in the same manner. However, the guide member 1 will be described below.

  As shown in FIG. 4, the configuration of another application example of the guide member is a configuration in which the guide member 1 and the arm 1A attached to the expansion / contraction means 4 are attached to the expansion / contraction means 4 via the rotation mechanism 30. ing. By this rotation mechanism, the guide member 1 can be rotated in the circumferential direction with respect to the vertical direction.

  With this configuration, for example, even when the flat wire is in contact with the guide member 1 and a frictional force that affects the yield strength value of the flat wire is generated, the guide member 1 is rotated around the vertical direction by the rotation mechanism 30. By rotating in the direction, that is, by rotating in the winding direction side of the flat wire to the inner body B1, it is possible to prevent an increase in the yield strength of the flat wire and damage to the surface plating.

  In addition, another application example of the above-described guide member is not limited to the above-described structure, and a structure in which the guide member 1 is fixed to the expansion / contraction means 4 and the expansion / contraction means 4 can rotate can be applied. Other structures are also designed with appropriate changes. In this case, for example, a ball bearing mechanism can be used as the rotation mechanism.

  Further, according to the flat wire winding device constructed by another application example of the guide member, the same effects as those of the above-described embodiment can be obtained.
