In a winding device in which a rectangular wire is wound around a bobbin, when the rectangular wires are slightly overlapped vertically, the flat portions of the rectangular wires are in contact with each other and are difficult to slide, making it difficult to align them in layers.
When the winding device that guides the square wire with the wire guide is used, the wire guide is moved in the bobbin axial direction while winding the square wire around the bobbin, and the square wire reaches the end of the bobbin. Therefore, it is necessary to detect that the end of the bobbin has been reached with a highly accurate winding detection sensor, and immediately switch the position of the line guide precisely. If the detection accuracy of the bobbin end is low or the timing for switching the position of the line guide is not set with high accuracy, the bobbin end is not aligned and the double line is wrapped around When the corner wire is folded or folded back in the direction away from the end of the bobbin, the square wire is wound in a state where it is not in close contact with the bobbin axial direction, resulting in a defective product.

  It is not technically impossible to wind up the square wire in a bobbin in a multi-layered arrangement by increasing the detection accuracy by the winding detection sensor, the accuracy of position control of the wire guide, and the like. However, in the case of a coil used for a small motor incorporated in the latest digital camera or mobile phone, for example, the winding thickness is about 50 μm and the bobbin outer diameter is about 6-8 mm. In the winding device for this purpose, it is necessary to extremely increase the above-mentioned various precisions, and the winding device becomes very expensive, and it is difficult to sufficiently improve the reliability of the performance of the device.

  An object of the present invention is to provide a winding device having a simple configuration for winding a rectangular wire around a bobbin, and to provide a winding device that can be manufactured at low cost by winding a rectangular wire around a bobbin.

The alignment plate is supported by the alignment plate support mechanism so as to be movable in a direction parallel to the axial direction of the bobbin, and is also supported so as to be movable toward and away from the peripheral surface of the bobbin. When winding, the square line is guided by the alignment plate so that the square lines are aligned in close contact with each other in the bobbin axial direction. Since the alignment plate is movable in the direction of approaching / separating from the peripheral surface of the bobbin, the bobbin can be wound with square lines in multiple layers.

  According to a second aspect of the present invention, there is provided the winding device according to the first aspect, wherein the alignment plate support mechanism is configured to bring a square wire into close contact with the alignment plate when the alignment plate moves in a direction parallel to the axial center direction of the bobbin.

Since the wire guide is provided at a position that is separated from the bobbin by a predetermined distance and corresponds to the intermediate position in the axial direction of the bobbin, until the square line reaches the intermediate position from the end of the bobbin, the angle is caused by the guiding action of the alignment plate. Lines are aligned closely.

  After the square line passes through the intermediate position of the bobbin, the square line is closely aligned by the guide action of the alignment plate and the guide action of the line guide. Next, when the alignment plate comes into contact with the flange portion of the bobbin at the end portion of the bobbin, the square line sinks under the inner peripheral side end portion of the contact portion due to the guide action of the guide surface opposite to the flange portion. Then, it moves to the inner peripheral side of the guide surface on the buttock side, and the square lines are closely contacted and aligned only by the guide action of the line guide. When the square line comes into contact with the collar part of the bobbin, the square line moves to a layer above the first layer.

Since a pair of guide surfaces are formed that are inclined with respect to the plane orthogonal to each other and that the square lines are closely aligned, the square lines are aligned when the alignment plate comes into contact with the bobbin collar. It can move below the inner peripheral edge of the plate, and can be wound by aligning the square line closely to the position of the bobbin's collar, and after the square line comes into contact with the collar, it is securely folded back in the folding direction. It can be wound in line with the shape.

The rotation speed is kept constant. Then, based on the detection signal from the rotation detection mechanism 30, the total length of the square wire 2 wound around the bobbin 3 is calculated in consideration of the wire diameter (wire width) of the square wire 2, and the angle of the set length is calculated. When the wire 2 is wound around the bobbin 3, the electric motor 21 is stopped and the bobbin 3 is exchanged.

  The wire guide 5 is spaced a predetermined distance from the bobbin 3 to the front side in FIG. 1 to guide the square wire 2 supplied to the bobbin 3 mounted on the winding shaft 10 and the bobbin mounting portion 11 of the winding shaft 10. Is provided at a position corresponding to an intermediate position in the axial direction of the bobbin 3 attached to the. The square line 2 supplied from the square line supply reel 4 is slightly bent by the line guide 5 and introduced horizontally into the bobbin 3.

  The alignment plate 6 guides the square wire 2 so that when the square wire 2 guided by the wire guide 5 is wound around the bobbin 3, the square wire 2 is closely aligned and aligned in the bobbin axial direction. The alignment plate 6 is made of a metal plate (for example, brass) having a low sliding resistance (for example, a thickness of about 300 to 400 μm). As shown in FIGS. 4 to 6, the alignment plate 6 is formed with a rectangular notch 6a at the corner of the rectangular plate, and is wound around the bobbin 3 or the bobbin 3 on two sides of the notch 6a, respectively. Further, contact portions 61 and 62 that contact at least a part of the peripheral surface of the rectangular wire 2 are formed. A pair of guides that are inclined with respect to the surface 3c perpendicular to the bobbin axis and are arranged in close contact with each other in the contact direction 61 and 62 and in the vicinity thereof. Guide surfaces 61a and 62a and flat surfaces 61b and 62b between them are formed. The inclination angle of the guide surfaces 61a and 62a with respect to the surface 3c perpendicular to the bobbin axis is about 45 degrees (for example, 40 to 50 degrees). The length of the guide wire 61a, 62a in the bobbin axial direction is (2-3) d, and the width of the flat surfaces 61b, 62b is also (2-3). d.

  The alignment plate support mechanism 40 supports the alignment plate 6 so as to be movable in a direction parallel to the axial direction of the bobbin, and supports the alignment plate 6 so as to be movable toward and away from the peripheral surface of the bobbin 3. It is. The alignment plate support mechanism 40 includes a movable rod 41 that is horizontally disposed parallel to the axial direction of the bobbin 3 and directly supports the alignment plate 6, and a slide member 42 that is inclined 45 degrees to support the movable rod 41. A base member 43 that guides the slide member 42 through a flat bearing (for example, a cross roller table) in a 45-degree tilt direction, a lower frame 44, an urging force adjusting mechanism 50, a ball plunger 60, and the like. Have.

  The alignment plate 6 is fixed to the left end portion of the movable rod 41 so as to be parallel to the surface orthogonal to the bobbin axis, and the movable rod 41 slides in the horizontal sliding hole 42a of the slide member 42 via lubricating oil. It is mounted in a penetrating manner so that it can move freely. The movable rod 41 is made of, for example, stainless steel, and the slide member 42 is made of, for example, brass. The movable rod 41 and the horizontal sliding hole 42a are machined with high precision, and the horizontal sliding hole is inserted through a predetermined type of lubricating oil. The sliding resistance acting on the movable rod 41 from 42a is configured to have a substantially constant magnitude. A small resistance is applied to the movable rod 41 from the horizontal sliding hole 42a of the slide member 42 through the viscosity of the lubricating oil. The movable rod 41, the horizontal sliding hole 42a, and the lubricating oil are connected to the alignment plate 6 by the bobbin 3. A resistance applying means for applying a small resistance for bringing the square wire 2 into close contact with the alignment plate 6 when moving in a direction parallel to the axial direction is configured.

  Since the magnitude of the sliding resistance varies depending on the viscosity of the lubricating oil in the horizontal sliding hole 42a (that is, the temperature of the lubricating oil), it is desirable to keep the temperature of the slide member 42 constant. Therefore, the upper surface of the slide member 42 is equipped with a cooler 45 that cools by a plurality of Peltier elements, and a temperature sensor 46 that includes a thermistor that detects the temperature of the slide member 42. Based on this detection signal, the cooler 45 is driven and controlled so that the temperature of the slide member 42 is always a constant temperature (for example, about 20 ° C.). However, the cooler 45 and the temperature sensor 46 are not essential and can be omitted.

  The slide member 42 is urged downward along the base member 43 by its own weight, that is, in a direction in which the alignment plate 6 approaches the peripheral surface of the bobbin 3, and the slide member 42 and the base member 43 bob the alignment plate 6. The urging means for urging in the direction approaching the peripheral surface 3 is configured. The urging force of the urging means may be very small, and an urging force adjusting mechanism 50 for precisely adjusting the urging force is provided. The biasing force adjusting mechanism 50 includes an arm member 51 fixed to the lower frame 43, a fixing nut 52 fixed to the arm member 51 in an inclined posture, a bolt member 53 screwed to the fixing nut 52, The urging force is adjusted by adjusting the position of the bolt member 53, which includes a fixing pin 54 fixed to the slide member 42, a tension coil spring 55 stretched between the bolt member 53 and the fixing pin 54. It is like that. The ball plunger 60 is provided at the tip of the horizontal arm 61 fixed to the arm member 51, and when the slide member 42 is retracted upward for exchanging the bobbin 3, the slide member 42 is lightly locked so as to be unlockable. .

Next, the operation and effect of the winding apparatus 1 described above will be described.
The empty bobbin 3 is mounted on the bobbin mounting portion 11 of the winding shaft 10 and the end of the square wire 2 extending from the rectangular wire supply reel 4 is fixed to the bobbin 3, and then the winding drive mechanism 20 is driven. The wire 2 is wound around the bobbin 3. The operation of the alignment plate 6 and the alignment plate support mechanism 40 at the time of winding the rectangular wire will be described with reference to FIGS. 7 (a) to 7 (f). In these drawings, the length of the bobbin 3 in the axial direction is shown smaller than the actual length.

  As shown in FIGS. 7A and 7B, for example, when the second layer of the square line 2 is wound around the bobbin 3, the square line 2 is aligned closely in the direction of the bobbin axis. In this way, the alignment plate 6 moves in the direction of the arrow while guiding the square 2. In this case, since the small sliding resistance as described above acts on the alignment plate 6, the guide surfaces 61 a and 62 a on the opposite side (right side) to the moving direction of the alignment plate 6 are kept in contact with the square line 2. The guide lines 61a and 62a align the square line 2 so as to be closely aligned in the bobbin axial direction, and receive a reaction force from the square line 2 to move in the direction of the arrow.

  As shown in FIG. 7 (c), when the side surface of the alignment plate 6 comes into contact with the flange portion 3b of the bobbin 3, the alignment plate 6 stops moving, but at that time, due to the guide action of the right guide surfaces 61a and 62a. The square line 2 sinks into the lower surface (inner surface) side of the flat surfaces 61b and 62b of the alignment plate 6 and is aligned. Here, since the line guide 5 is fixedly disposed at a position corresponding to the intermediate position in the axial direction of the bobbin 3, in the state where the alignment plate 6 has stopped moving as shown in FIG. The square lines 2 are aligned in close contact by the guiding action of the guide 5. Although the flat surfaces 61b and 62b are in contact with the circumferential surface of the wound rectangular wire 2, the flat wire 61b, 62b is not sharp and does not damage the rectangular wire 2.

  As shown in FIG. 7 (d), when the square line 2 reaches the collar 3 b of the bobbin 3, the square line 2 moves to the third layer outside the first layer, but the collar 3 b is guided by the guide action of the line guide 5. Since it is guided in a direction away from the center, it does not move from the third layer to the fourth layer at the flange portion 3b, but is arranged in the third layer as shown in FIG. At this time, the square line 2 is kept in contact with the left guide surfaces 61a and 62a, and the square line 2 is pushed toward the flange 3b by the guiding action of the guide surfaces 61a and 62a. Are aligned side by side in the bobbin axial direction. Thereafter, in the same manner as described above, 10-15 layers are wound in a multilayered manner.

  The inclination angle of the guide surfaces 61a and 62a with respect to the plane orthogonal to the bobbin axis is preferably about 45 degrees, and is preferably in the range of at least 40 to 50 degrees. When the inclination angle is smaller than 40 degrees, when the alignment plate 6 comes into contact with the flange portion 3b of the bobbin 3, the square line 2 is below the inner peripheral side end portion of the alignment plate 6 as shown in FIG. It becomes difficult to dive into. When the inclination angle is greater than 50 degrees, the square line 2 is folded back at the position of the flange 3b of the bobbin 3 and then comes into close contact with each other.

  It is desirable that the length in the bobbin axial direction of the guide surfaces 61a and 62a is (2-3) d, where d is the width of the square line 2 in the bobbin axial direction. When the length of the guide surfaces 61a, 62a in the bobbin axial direction is smaller than the above value, the square line 2 is below the inner peripheral side end of the alignment plate 6 when the alignment plate 6 contacts the flange 3b. It becomes difficult to dive. When the length of the guide surfaces 61a and 62a in the bobbin axial direction is larger than the above value, the square line 2 is folded back at the position of the flange portion 3b and then comes into close contact with each other.
