Description

  The present invention relates to a flyer type winding device that winds around the outer periphery of a work by rotating a flyer portion.

  When continuously performing coil winding, a flyer type winding device is generally used. In the flyer type winding device, the work side to be wound is stationary, and the arm itself called the flyer part rotates around the work while supplying the wire, thereby winding the wire around the work. It is a wire device. By using a flyer type winding device, the winding tact can be shortened by winding continuously without cutting the wire from one workpiece to the next. Reference 1).

  By the way, in the flyer type winding device, the wire itself is twisted one turn at a time for one winding because of the property that the flyer portion rotates. Here, when the wire is a round wire (wire having a circular cross section), it can be said that there is not much fear of damaging the product quality even if twisted. However, in recent years, products using wires other than round wires (non-circular cross-section wires having a rectangular cross section, etc.) have been increasing, so efficient winding using non-circular cross-section wires in a flyer type winding device. In the case of a non-circular cross-section wire, it is difficult to wind the wire tightly without a gap if the wire is twisted.

  In the flyer type winding device, one of the causes of twisting of the wire is that the wire is twisted by one turn per winding as described above, and yet another cause is It is in the drawing direction of the wire from the spool which is the supply source of the wire. When the wire is drawn out from the stationary spool toward the outside in the axial direction of the spool, the wire is drawn out in a spiral shape, which causes a twist of one turn per one drawing.

  The present invention has been made in view of such problems of the prior art, and an object of the present invention is to provide a flyer-type winding device that can perform winding without twisting even when a non-circular cross-section wire is used, for example.

The flyer type winding device of the present invention is a flyer type winding device that performs winding on a work by rotating the flyer part.
Spools that have accumulated wire,
A first motor for rotating the spool;
A fryer section to which a wire is supplied from the spool;
A second motor for rotating the fryer portion around the workpiece;
A control device for adjusting the rotational speed of the first motor and the second motor;
After drawing the wire from the spool to the outside in the direction perpendicular to the axis, it is supplied to the flyer part,
The control device changes a speed difference between the first motor and the second motor according to an amount of the wire supplied from the spool and an amount of the wire consumed from the flyer portion. Features.

  First, in the present invention, a wire rod is pulled out from the rotating spool in the direction orthogonal to the axis, and then supplied to the flyer portion, thereby eliminating one cause of the wire rod being twisted.

  Further, in the flyer type winding apparatus, the problem that the wire is twisted by one turn per winding is solved in the present invention as follows. That is, while the spool is rotated by the first motor, the wire wound around is unwound and supplied to the flyer portion that is driven to rotate by the second motor. Can be eliminated. However, since the wire length necessary for the winding is not supplied simply by matching the rotation of the spool and the rotation of the flyer part, it is necessary to rotate while maintaining a speed difference corresponding to the length. Even if the rotation is performed while maintaining a theoretical speed difference, the amount of the wire supplied from the spool and the amount of the wire consumed from the flyer portion do not always coincide with each other. When the amount of the wire rod supplied from the spool is larger than the amount of the wire rod consumed from the fryer part, the wire rod is loosened, resulting in an inappropriate winding, and conversely, the wire rod supplied from the spool When the amount is smaller than the amount of the wire consumed from the fryer part, the wire may be cut. Therefore, in the present invention, the control device determines the speeds of the first motor and the second motor according to the amount of the wire supplied from the spool and the amount of the wire consumed from the flyer portion. By changing the difference, proper winding is performed.

  Furthermore, a pulley device that engages with a wire rod is provided between the spool and the flyer portion, and the pulley device is configured such that the amount of the wire rod supplied from the spool is consumed from the flyer portion. When the amount of wire rod supplied from the spool is smaller than the amount of wire rod consumed from the flyer portion, it moves in the other direction. Furthermore, it is preferable to have a sensor that detects the position of the pulley device and outputs a signal to the control device. As a result, the pulley device functions as a temporary accumulating unit for the wire supplied to the flyer unit, and the control device frequently changes the speed difference between the first motor and the second motor. There is no need.

  The rotation axis of the spool is preferably coincident with the rotation axis of the flyer portion. Since the spool generally has a rotationally symmetric shape, if the rotating shaft is rotated so as to coincide with the rotating shaft of the flyer portion, there is little risk of swinging and stable winding operation is possible. become.

  Although the present invention is effective for winding a non-circular cross-section wire, it is needless to say that a circular cross-section wire may be used.

It is a flowchart which shows control of the control apparatus CONT.

  The present embodiment will be described with reference to the drawings. FIG. 1 is an overall view of a flyer type winding device. In FIG. 1, a frame 11 is disposed on a pedestal 10, and a winding device 20 is attached to the frame 11. A support disk 12 is arranged on the pedestal 10 so as to be movable up and down by a driving device 13, and the support disk 12 has a plurality of workpieces 14 implanted therein.

  FIG. 2 is an enlarged view of the winding device 20. A first motor 21 is supported on the frame 11. The rotating shaft of the first motor 21 is connected to the small gear 22 so as to rotate integrally. Further, a large gear 23 is rotatably supported on the frame 11 so as to be attached to the first motor 21. The small gear 22 and the large gear 23 are arranged between the first gear 21 and the first gear 21. It meshes with the toothed belt 24.

  The large gear 23 rotates integrally with the spool shaft 24 by serration coupling or the like. The spool shaft 24 has a spool 25 wound around a wire W having a rectangular cross section, and is attached to the periphery so as to be detachable, and is rotated integrally therewith. An upper end of the spool shaft 24 is rotatably supported by a bearing 26 with respect to the frame 11. The lower end of the spool shaft 24 is supported by the upper end of the fryer assembly 40 via a bearing 27 so as to be relatively rotatable. That is, the spool shaft 24 is coaxial with the flyer assembly 40.

  The flyer assembly 40 has a hollow and substantially cylindrical shape, and a disk-like support portion 41 that supports the spool shaft 24, a large gear 42, and a cylindrical flyer base portion 43 are coaxially connected. The upper end and the lower end of the flyer base portion 43 are rotatably supported by the frame 11 via bearings 28 and 29. A pipe 44 (or a pipe with a wire guide) is planted on the upper surface of the disk-shaped support portion 41 so as to extend in parallel with the spool shaft 24. The upper end of the pipe 44 is located at the center height of the spool 25.

  Further, a second motor 30 is attached to the frame 11 along with the large gear 42. A small gear 31 is connected to the rotation shaft of the second motor 30, and the small gear 31 and the large gear 42 mesh with a second toothed belt 32 stretched between the two. The first motor 21 and the second motor 30 are rotationally driven independently by a drive signal from the control device CONT.

  A pulley device 50 described later is disposed inside the flyer base 43. At the lower end of the flyer base 43, a wire guide 45 bent in a dogleg shape is formed so as not to interfere with the workpiece 14. The wire W drawn out from the spool 25 in the direction orthogonal to the axis line enters the inside of the pipe 44 from the upper end of the pipe 44, passes through the hollow fryer assembly 40, reaches the lower end of the flyer base 43, and reaches the wire guide 45. To reach the work 14. A rod-shaped work holding member 34 extending coaxially downward from the flyer base 43 is movable relative to the flyer base 43 in the axial direction, and its lower end is set to the upper end of the work 14 during winding. By abutting, the swing of the wire guide 45 is suppressed.

  3 is a cross-sectional view showing the inside of the flyer base 43, and FIG. 4 is a cross-sectional view of the configuration of FIG. 3 taken along line IV-IV and viewed in the direction of the arrow. A box 51 is inserted and fixed in the flyer base 43. As shown in FIG. 4, the box 51 includes a case 51a and a lid 51b. A pair of rails 51 c extend in the axial direction of the flyer base 43 in the case 51 a.

  As shown in FIG. 3, a substantially pentagonal frame 52 is arranged in the box 51. The top 52 is provided with two rollers 53 rotatably attached to both sides, and each roller 53 can roll on the rail 51c. Therefore, the top 52 is guided by the rail 51c and can move up and down in the box 51. As shown in FIG. 4, by placing the rotation center O of the flyer base 43 in the cross section of the top 52, it is possible to suppress the swing of the top 52 as much as possible during winding. Preferably, the center of gravity of the top piece 52 is made to coincide with the rotation center O.

  A pulley 54 is attached to the upper end of the top 52 so as to be rotatably supported by the rotary shaft 52a. On the other hand, a pulley 55 is attached to the upper portion of the box 51 so as to be rotatably supported by the rotary shaft 51d. The wire W that has entered from the pipe 44 (FIG. 2) travels downward through the upper guide 43a of the flyer base 43, is wound around the pulley 54, travels upward, and is further wound around the pulley 55 and travels downward. Toward the wire guide 45 through the lower guide 43b. A pulley device 50 is configured by the top 52 and the pulleys 54 and 55.

  An upper sensor 56 is attached to the upper end of the box 51, and a lower sensor 57 is attached to the lower end of the box 51. For example, the sensors 56 and 57 project light on the inside of the box 51 and receive the reflected light, thereby transmitting the output signal to the control device CONT and detecting the position of the top 52. However, the detection mode of the sensor is not limited to light, and various types such as magnetism and contact type are conceivable.

  Next, the operation of the flyer type winding device will be described. 5 to 7 are diagrams showing the position of the frame 52 in the box 51. FIG. FIG. 8 is a flowchart showing the control of the control device CONT. First, the operator sets the spool 25 on the spool shaft 24. Here, the winding direction of the wire W in the spool 25 is opposite to the rotation direction of the spool shaft 24 (when the spool 25 is rotated in the direction opposite to the rotation direction, the wire W is wound around the spool 25). In the set state, the wire rod W is pulled out from the spool 25 and enters the inside of the pipe 44 from the upper end of the pipe 44, passes through the pool device 50 inside the fryer assembly 40, and passes through the wire guide 45 to the workpiece 14. Connect to At this time, the initial position of the frame 52 is preferably near the center of the box 51.

  In this state, when a switch (not shown) is turned on, the control device CONT supplies power to the first motor 21 and the second motor 30 in step S101 of FIG. The large gears 23 and 42 are rotated in the same direction via the belts 24 and 32. As a result, the wire rod guide 45 turns around the workpiece 14, whereby the wire rod W is wound around the workpiece 14. The wire W is supplied from the spool 25 side by the amount wound around the work 14. Further, in synchronization with the turning of the wire rod guide 45, the drive device 13 moves the support disk 12 up and down, whereby the wire rod W is uniformly wound around the entire work 14.

  Here, the speed of the first motor 21 and the speed of the second motor 30 vary depending on the diameter of the workpiece 14, the diameter of the spool 25, and the like. However, when supplying the wire W from the spool 25 in the initial state, when the small gears 22 and 31 are rotated at the speeds V1 and V2, respectively, the amount of the wire W supplied by the pulley device 50 and the flyer base 43 It is preferable to obtain in advance a setting speed at which the amount of the wire W consumed from the wire guide 45 (passing through the wire guide 45 by the amount wound around the workpiece 14) becomes equal.

  Therefore, immediately after starting the first motor 21 and the second motor 30 at the set speeds V1 and V2, the frame 52 stays at the center of the box 51 as shown in FIG. Therefore, since the sensors 56 and 57 do not detect the frame 52 in step S102 in FIG. 8 (both steps S103 and S105 in FIG. 8 are negative), the control device CONT sets the set speed V1 of the first motor 21 and Control is performed so as to maintain the set speed V2 of the second motor 30.

  Here, as the winding progresses, the amount of the wire W consumed from the wire guide 45 of the flyer base 43 may increase more than the amount of the wire W supplied by the pulley device 50. In such a case, since the amount of the wire W entering the pulley 54 of the pulley device 50 is smaller than the amount of the wire W coming out of the pulley 55, the top 52 gradually rises. Then, as shown in FIG. 6, since the upper end of the top 52 reaches the upper end of the box 51, the upper sensor 56 outputs a signal to the control device CONT (Yes in step S103 in FIG. 8). The speed difference is changed by increasing the speed of the first motor 21 or decreasing the speed of the second motor 30 (step S104 in FIG. 8). As a result, the amount of the wire W entering the pulley 54 of the pulley device 50 becomes larger than the amount of the wire W coming out of the pulley 55, so that the top 52 is gradually lowered and there is no fear of coming out of the box 51.

  On the other hand, the amount of the wire W consumed from the wire guide 45 of the flyer base 43 is smaller than the amount of the wire W supplied by the pulley device 50, and the amount of the wire W entering the pulley 54 of the pulley device 50 is When the amount of the wire W coming out of the pulley 55 becomes larger, the piece 52 gradually descends. Here, as shown in FIG. 7, when the lower end of the top 52 reaches the lower end of the box 51, the lower sensor 57 outputs a signal to the control device CONT (Yes in step S105 in FIG. 8). Then, the speed difference is changed by decreasing the speed of the first motor 21 or increasing the speed of the second motor 30 (step S106 in FIG. 8). As a result, the amount of the wire W entering the pulley 54 of the pulley device 50 becomes smaller than the amount of the wire W coming out of the pulley 55, so that the top 52 gradually rises and there is no possibility of coming out of the box 51.

  According to the present embodiment, the control device CONT uses the first motor 21 according to the amount of the wire W supplied from the spool 25 and the amount of the wire W consumed from the wire guide 45 of the flyer base 43. By changing the speed difference between the second motor 30 and the second motor 30, appropriate winding can be performed.

  The control device CONT determines that the winding is finished when the wire guide 45 turns around the work 14 a predetermined number of times (step S107 in FIG. 8), and the first motor 21 and the second motor 30 are determined. Stop power supply to. After that, since the support disk 12 rotates, another work 14 is positioned below the fryer base 43, so that the wire W can be wound around the other work 14 in the same manner as above without cutting the wire W. it can.

  When the winding direction of the wire W on the spool 25 is the same as the rotation direction of the spool shaft 24, the control device CONT decreases the speed of the first motor 21 or sets the second speed in step S104. The speed difference is changed so as to increase the speed of the motor 30, and the speed difference of the first motor 21 is increased or the speed of the second motor 30 is decreased in step S106. To change. An appropriate tension value is required for the winding. In this case, about one half of the weight of the top 52 is the winding tension. A mechanism for adjustment is necessary, but as an alternative, a device for applying tension to the wire W may be provided in either of them. Furthermore, the present invention is also applied to a flyer type winding device that rotates a workpiece together with a fryer portion.
