Description

  The present invention relates to a winding method and apparatus that achieves automation so that a simple configuration and downsizing can be achieved and a specification can be easily changed when winding a coil in multiples.

  Conventionally, for example, when manufacturing a multi-coil of α winding (the winding start and winding end leads are both outer circumferences, also referred to as outer winding), one α winding coil is manufactured, and these lead wires Are connected to each other with solder or the like to form a multiple coil. (See Patent Documents 1 and 2)

  In addition, when connecting a coil with a normal axial winding method instead of an α winding coil, it is necessary to arrange winding cores (bobbins) in the direction of the rotation axis. After winding the winding core on one of the winding cores while pressing the winding core from the left and right spindle shafts via the plate, the wire rod crosses over the relay plate and winds it on the other winding core adjacent in the axial direction. I was doing.

However, in recent years, it has been required to wind α-windings and normal-winding coils in multiples. However, it is difficult to automatically connect α-winding coils in multiples, and this has been achieved. There is no line method and apparatus. In the normal winding coil, multiple winding is realized by the flyer method, but in the axial rotation method, two windings are at most. When trying to wind more multiple coils, the spindle becomes the core. There was a problem that the core could not be pressed down and the core would come off during winding. The present invention has been made to solve the above problems. (1) A winding method and apparatus for automatically winding α-coil by connecting multiple α-coil. It is an object of the present invention to provide a winding method and apparatus for automatically winding by connecting to multiple units.

(1) To connect α winding coil in multiples and wind it automatically
(1) -1: The wire rod fed from the tip of the wire rod supply section rotating around the core is chucked by the wire rod holding means , and the wire rod is moved in a direction orthogonal to the rotation axis to draw the wire rod a predetermined length. After that, the winding core is rotated so that the drawn wire is wound around the winding core, and the wire feeding portion is rotated at a double speed in the same direction as the winding core rotation direction so that the wire fed from the wire feeding portion is wound around the winding core. Wrap around. By this operation, one α-winding coil is wound. Thereafter, in order to obtain a connecting coil, the α winding coil wound around the winding core is first removed from the winding core. Then, the wire rod between the winding end lead of the α-winding coil and the wire rod supply section is chucked by the wire rod holding means, and the wire rod is pulled out by a predetermined length by moving in the direction perpendicular to the rotation axis together with the wound coil. . Then, the winding core is rotated, the drawn wire is wound around the winding core, and the wire supply portion is rotated at a double speed in the rotation direction of the winding core, so that the wire fed from the wire supply portion is wound around the winding core. By this operation, the second α-winding coil is connected to the first α-winding coil and wound. Thereafter, similarly, the α winding coil is removed from the winding core. In the same manner, the same operation is repeated to wind the connected multiple α winding coils. The length of the connecting wire between the connected α-winding coils can be appropriately adjusted by changing the chucking position of the wire rod between the wire-feeding portion and the winding end lead of the α-winding coil. In this case, the rotating spindle shaft is single, and the wound α-coil can be removed from the winding core, and the α-coil connected in multiple can be wound by changing the chuck.

(1) -2: A plurality of spindle shafts are arranged in parallel, the tip of the wire rod fed from the wire rod supply unit is held by a chuck, and the wire rod between the chuck and the wire rod supply unit is held by a wire rod drawing means, and the spindle The wire held in the direction perpendicular to the axis is moved. By this operation, a wire having a predetermined length is pulled out. In this state, by rotating the spindle shaft, the drawn wire is wound around the core at the tip of the spindle shaft, and by rotating the wire supply unit at the double speed in the same direction as the rotation direction of the spindle shaft, The wire drawn from the wire supply unit is wound around the core. At this time, the drawn wire is given a predetermined tension and wound around the core. By this operation, one α-winding coil is wound. Next, the spindle shaft is moved in a direction orthogonal to the axial direction, and the wire rod supply unit is opposed to the spindle shaft to which a new winding core is fixed. Here, the wire rod between the coil already wound around the winding core and the wire rod supply unit is held by the wire rod drawing means , and the wire rod held in the direction orthogonal to the spindle axis is moved. By this operation, a wire having a predetermined length is pulled out. In this state, by rotating the spindle shaft, the drawn wire is wound around the core at the tip of the spindle shaft, and by rotating the wire supply unit at the double speed in the same direction as the rotation direction of the spindle shaft, The wire drawn from the wire supply unit is wound around the core. By this operation, the second α-winding coil is connected to the first α-winding coil and wound. Here, the spindle shaft is moved again in the direction orthogonal to the axial direction of the spindle shaft, and the wire rod supply unit is opposed to the spindle shaft to which a new winding core is fixed. Thereafter, the same operation was repeated, and the connected multiple α-winding coils were wound. In this case, since the wire is pulled out from both sides of the holding portion, there is an advantage that the height in the pulling direction can be reduced.

(2) For automatic winding by connecting multiple axis normal winding coils
(2) -1: The wire rod fed from the tip of the wire rod supply section that rotates in synchronization with the rotation axis of the winding core is chucked by the wire rod holding means , and the chuck is moved in the direction perpendicular to the rotation axis to move the wire rod. Pull out a predetermined length. Next, the wire rod supply unit is rotated in synchronization with the rotation shaft, and the wire rod drawn by the chuck is wound around the core of the rotation shaft. At this time, a predetermined tension is applied to the wire, and the wire moves toward the core. When the chuck reaches the vicinity of the core, stop the rotation of the spindle shaft and release the chuck. Next, the normal winding coil is removed from the winding core. Then, the wire between the coil lead and the wire supply unit is held by the wire holding means and the wound coil is moved again in the direction perpendicular to the rotation axis to draw out the wire by a predetermined length. Then, the wire rod supply unit is rotated in synchronization with the rotation shaft, and the wire drawn by the wire rod supply unit is wound around the core of the rotation shaft. Thereafter, winding was performed in the same manner, and a multiple-rotating coil was wound. In this case, there is an advantage that multiple coils can be wound around one axis, and the length of the connecting wire between the coils can be arbitrarily adjusted by the position where the lead portion of the coil that has been wound is chucked.

(2) -2: A plurality of spindle shafts are arranged in parallel, the tip of the wire rod fed out from the wire rod supply portion rotating in synchronization with the spindle shaft is held by the chuck, and the wire rod between the chuck and the wire rod supply portion is wire rod The wire held by the drawing means and held in a direction perpendicular to the spindle axis is moved. By this operation, a wire having a predetermined length is pulled out. In this state, by rotating the spindle shaft and the wire rod supply unit synchronously, the drawn wire rod is wound around the core fixed to the tip of the spindle shaft. Next, the spindle shaft is moved in a direction orthogonal to the axial direction, and the wire rod supply unit is opposed to the spindle shaft to which a new winding core is fixed. Here, the wire rod between the coil already wound around the winding core and the wire rod supply unit is held by the wire rod drawing means , and the wire rod held in the direction orthogonal to the spindle axis is moved. By this operation, a wire having a predetermined length is pulled out. In this state, by rotating the spindle shaft and the wire rod supply unit synchronously, the drawn wire rod is wound around the core fixed to the tip of the spindle shaft. In this way, the shaft-rotating type coil is connected and wound. Hereinafter, in the same manner, a multiple shaft-turning type coil is wound by winding. In this case, since the wire is drawn from both sides of the holding portion, there is an advantage that the height in the drawing direction can be reduced.

  The length of the connecting wire between the connected α-winding coil and the axial winding coil can be adjusted as appropriate by changing the chuck position of the wire rod between the wire supply portion and the winding end lead of the α-winding coil and the axial winding coil. Further, the rotating spindle shaft is one, and the wound α winding coil and the shaft turning coil can be removed from the winding core, and the α winding coil connected in multiple can be wound by changing the chuck.

  The lead wire wound around the cores of the α-winding coil and the shaft-turning coil has an advantage that the height in the pull-out direction can be reduced because the wire is drawn from both sides of the wire holding portion. In addition, since the spindle axis is multi-axis, work tact time can be shortened.

  A first embodiment of the present invention will be described. The configuration of the apparatus of the first embodiment is as follows.

  As shown in FIG. 1, a spindle shaft 1 that rotates about the shaft center, a spindle motor 2 that drives the spindle shaft, a moving mechanism 3 in the axial direction of the spindle shaft 1, a spindle moving motor 4, and a spindle shaft 1 tip. A fixed winding core 5, a flyer 6 that faces the spindle shaft 1 and rotates around the spindle, a flyer motor 20 that rotates the flyer, a moving mechanism 8 of the flyer 6 in the spindle shaft 1 direction, and a flyer moving motor 9, a nozzle 10 that feeds the wire 21 provided at the tip of the flyer 6, a chuck 12 that holds the tip of the wire 21 fed from the nozzle 10, and the chuck 12 can be moved in a direction perpendicular to the spindle shaft 1. It comprises a wire chuck mechanism 13 and a winding core moving mechanism 15 that houses the winding core in the spindle shaft 1.

  Based on the above configuration, the winding method of the multi-coil of the α winding coil will be described.

  First, as shown in FIGS. 3A to 3G, the wire 21 is pulled out from a wire spool (not shown), inserted through a hollow rotating shaft of a rotating flyer 6 through a tension device (not shown), and the tip of the flyer 6 is inserted. The arm 7 is inserted into a hollow nozzle 10 fixed to the arm 7.

  The wire 21 fed out from the nozzle 10 is held by a chuck 12 that moves in an upward direction orthogonal to the spindle shaft 1, and the wire 21 having a predetermined length is drawn from the nozzle 10 by the movement of the chuck 12 by the servo motor 14. The chuck 12 is fixed to a belt 25 that is hung on a pulley 27 of the servo motor 14 via a moving table 23 and a relay plate 24 on the guide rail 26 so that the chuck 12 moves as the belt 25 moves. It has become.

  On the other hand, the flyer 6 is also moved by the flyer moving motor 9 of the flyer moving mechanism 8 to the center of the winding body of the winding core 5, and the wire 21 fed from the nozzle 10 of the flyer 6 is wound around the winding core 5 once. The wire 21 is fixed to the core 5.

  From this state, the core 5 rotates, for example, in the clockwise direction, and the spindle shaft 1 moves by the wire diameter every rotation, so that the windings are aligned and wound in multiple layers. As a result, the wire 21 drawn out by the chuck 12 is wound around the core 5, but the chuck 12 also moves downward in synchronization with the rotation of the core 5, and a certain tension necessary for the winding is applied. Thus, the downward movement of the servo motor 14 is controlled. At this time, in order to make the movement of the wire 21 accurate, the wire guide member 17 that can move together with the spindle shaft 1 can be used for more accurate winding. The wire guide member 17 is configured to pinch the wire 21 with pins from both sides, and can be moved by a wire guide moving cylinder 18, which obstructs when the chuck 12 moves to the vicinity of the wound coil. It can be evacuated so as not to become.

  At the same time, the flyer 6 rotates around the core 5 at a double speed in the same direction as the direction of rotation of the core 5. Thereby, the wire 21 fed out from the flyer 6 is also wound around the core 5 at the same time. At this time, the flyer 6 also moves in the axial direction of the core 5 and is aligned and wound in multiple layers. In this case, since the core 5 moves in the direction of the axis of the wire diameter every rotation, the flyer 6 moves by the diameter of the two wires every rotation. As a result, the wire end lead at the end of winding is positioned on the outermost periphery both on the winding side by the rotation of the winding core 5 and on the winding side by the rotation of the flyer 6. The wound multiple coil has a shape as shown in FIG.

  Of course, the winding 21 by the rotation of the winding core 5 and the winding by the rotation of the flyer 6 can each be performed in multiple layers in two rows. In this case, the winding 5 and the flyer 6 are wound in the stationary position without being fed in the direction of the rotation axis. In this case, a mechanism for moving the spindle shaft 1 and the flyer 6 in the axial direction is unnecessary. The multiple coil wound in this way has a shape as shown in FIG. In addition, in order to restrict | limit the winding width of a coil if necessary, you may provide the center pressing board 22 in the flyer 6 side. The center presser 22 is rotatable with respect to the flyer 6.

  Thus, when one α-winding coil is wound, the winding core 5 is retracted into the spindle shaft 1. The winding core 5 is normally pushed out in a protruding direction by a cylinder passing through the spindle shaft 1, but when retracted into the spindle shaft 1, the spindle shaft 1 is driven by the winding core moving cylinder 16 of the winding core moving mechanism 15. Retreat in. By this operation, the α-winding coil is detached from the core 5.

  Next, the chuck 12 is opened to release the wire rod 21, the chuck 12 of the wire rod chuck mechanism 13 is moved, and the wire rod 21 fed out from the nozzle 10 of the flyer 6 is moved in the vicinity of the winding end lead on the flyer 6 side. Chuck. The length of the connecting wire between the coils can be adjusted by adjusting the chuck position.

  Then, the chuck 12 is again moved upward by the servo motor 14 of the chuck mechanism 13 to pull out the wire 21 from the nozzle 10 for a predetermined length. At this time, the already wound α winding coil moves upward together with the chuck 12. The movement of the chuck 12 can be replaced with an air cylinder or the like, instead of the servo motor 14.

  Then, by repeating such an operation as many times as necessary, multiple α-winding coils can be manufactured.

Next, a second embodiment will be described. The configuration of the apparatus is the same as that of the first embodiment.
The second embodiment relates to a winding method of a multiple number of normal winding shaft-turning coils. In this case, the difference from the first embodiment is that the flyer 6 has the same rotational direction as the winding core 5. The only difference is that it rotates at the same speed in the direction.

  When the flyer 6 rotates at the same speed in the same direction as the rotation direction of the core 5, the wire 21 is not wound around the core 5 depending on the flyer 6, and the wire 21 is just at the end of the core 5. The same effect as when the winding 21 is rotated with the shaft fixed. Therefore, the wire 21 drawn from the nozzle 10 by the chuck 12 is wound around the winding core 5 with a certain tension. Also in this case, the coil can be wound in either a multi-row multilayer or a single-row multilayer. In this case, the coil shape is a shape as shown in FIG. 5D in the case of a multi-layered multi-row, and is shown in FIG.

Next, a third embodiment will be described. This assumes the case where the shapes of the coils connected in the first and second embodiments are different, and therefore the shape and diameter of the core 5 are different.
For example, one coil is round and the other coil connected adjacently is square.

  In this case, for example, two spindle shafts 1 are arranged in parallel so as to be laterally movable with respect to the flyer 6. In this case, a lateral movement motor 19 for laterally moving the two rows of spindles is added. First, as described in the above description, an α-winding coil or a normal winding shaft-turning coil is wound around one round core 5. Then, the coil wound around the core 5 is removed from the core 5, the spindle shaft 1 is moved laterally, and the other square core 5 is opposed to the flyer 6. The wire rod 21 between the coil winding end lead and the nozzle 10 of the flyer 6 is held by the chuck 12, and the chuck moving mechanism 13 moves the chuck 12 together with the coil wound upward of the winding core 5. 21 is pulled out from the nozzle 10 for a predetermined length.

Here, in the case of an α-winding coil, the flyer 6 is rotated in the same direction as the winding core at twice the speed, and in the case of a normal winding shaft-rotating coil, it is rotated at the same speed in the same direction as the winding core.
By winding in this way, two linked coils are formed. Further, if it is desired to connect the round coil again, the wound coil is removed from the core 5 and the spindle shaft 1 is moved back in the horizontal direction, and the round core 5 and the flyer are again connected. 6 is confronted.

Then, by repeating the same operation, three coils are connected and wound.
Therefore, it is also possible to form a multi-connected coil by mixing α winding coil and normal winding axis turning coil in an arbitrary arrangement.

  Next, a fourth embodiment will be described. The configuration of the winding device of the fourth embodiment is as follows as shown in FIG. A spindle base 28 that accommodates a spindle shaft 1 that rotates about a plurality of axes and that can be moved on a guide rail in a direction perpendicular to the spindle axis by a spindle lateral movement mechanism 45 and a spindle lateral movement motor 46; In the spindle drive mechanism 29 configured to be able to contact and separate from the spindle shaft, the output shaft 30 is spline-processed, spline-coupled with the accommodating portion in the spindle shaft 1, and the spindle motor 31 that rotates integrally with the spindle shaft 1, and the spindle motor movement A cylinder 32, a winding core 5 held by the spindle shaft 1, a flyer 6 that rotates around the winding core 5 against the winding core 5, and a flyer rotation motor 20 that rotates the flyer 6 via a pulley and a belt. And a nozzle 10 that is attached to the tip of the flyer 6 and passes through the wire 21, and is fed from the nozzle 10 In the wire pulling mechanism 34 that hooks the wire 11 between the clamp 11 that holds the wire 21 to be wound and the winding end lead of the clamp 11 or coil and the nozzle 10 at the tip of the flyer 6 and draws the wire upward, the pulley of the hook portion A relay plate 36 that holds 35, a guide base 38 that moves on a guide rail 37 that is fixed to the relay plate 36, a moving plate 39 that is fixed to the guide base 38, a belt 40 that fixes the moving plate 39, and a belt 40 A hook portion moving mechanism 43 is provided which is wound around a pulley 42 fixed to the output shaft of the hook moving motor 41 and moves the pulley 35 of the hook portion back and forth. Further, a spindle moving mechanism 33 in the axial direction of the spindle shaft 1 and a flyer moving mechanism 44 in the axial direction of the flyer 6 are provided as necessary.

With the above configuration, the following operations are performed as shown in the process diagrams of FIGS. 4A to 4F.
First, the spindle shaft 1 at one end of the spindle base 28 is opposed to the flyer 6. A wire 21 drawn from a wire rod spool (not shown) is inserted into the nozzle 10 at the tip of the flyer 6 through a tension device (not shown) from a hollow rotating shaft of the rotating flyer 6, and an arm through an arm 7 at the tip of the flyer 6. 7 is inserted through a hollow nozzle 10 fixed to the nozzle 7.

  The wire 21 fed from the tip of the nozzle 10 is held by the clamp 11 fixed to the side surface of the spindle base 28. From this state, the wire 21 between the clamp 11 and the nozzle 10 is hooked by the wire drawing mechanism 34 and drawn upward. The structure of the hook portion of the wire lead-out mechanism 34 may be, for example, a rod-like member provided with the pulley 35 at the tip, or may be a hook pin.

  When the wire 21 having a predetermined length is pulled out, the flyer 6 moves forward, and the wire 21 fed out from the flyer 6 is positioned at the center of the winding body portion of the core 5. At this time, if necessary, a center presser 22 that controls the winding width by pressing the end of the core 5 may be provided. Prior to winding, the flyer 6 is rotated once around the core 5, the wire 21 is fixed, and the subsequent winding of the core 5 and the winding by rotation of the flyer 6 are stabilized. To do.

  When the flyer 6 is positioned at the center of the winding body portion of the core 5, the core 5 is rotated and the flyer 6 is rotated at the double speed of the rotation of the core 5 in the same direction as the rotation direction of the core 5. As a result, the wire 21 drawn out by the wire drawing mechanism 34 is wound around the winding core 5 by the rotation of the winding core 5, and the flyer 6 is rotated around the winding core 5 by the rotation of the flyer 6. The wire 21 drawn out from 6 is wound around. As described above, if winding is performed in two rows and multiple layers, both the core 5 and the flyer 6 may be wound at the same position. By doing so, the wire rod 21 wound up in one row multilayer by the flyer 6 and the wire rod 21 drawn out by the wire rod drawing mechanism 34 by the rotation of the winding core 5 are wound up on the winding core 5 in one row multilayer. . Thus, the lead portions at the end of each winding are positioned on the outermost periphery of the coil, and two rows of α-winding coils are manufactured.

  Of course, it is also possible to wind each in a multi-row multilayer. In this case, for example, the above-described spline shaft may be used so that the rotation of the spindle shaft 1 is transmitted even when the spindle shaft 1 moves in the axial direction of the core 5. Similarly, the flyer 6 may be configured to be movable in the axial direction of the core 5 as described above. In this case, for each rotation of the winding core 5, the spindle shaft 1 is moved by the wire diameter in the axial direction and aligned and wound, and when the predetermined winding width is reached, the moving direction of the shaft is reversed to form a multi-row multilayered wire rod. Roll up. Similarly, on the flyer 6 side, the flyer 6 is moved in the double axis direction of the wire diameter per rotation of the flyer 6 as described above. When the predetermined winding width is reached, the moving direction of the flyer 6 is reversed and aligned winding is performed in multiple rows and multiple layers. By winding in this way, the winding ends of the wire 21 become the outermost periphery, and a multi-row α-winding coil is manufactured.

  As described above, when one α-winding coil is wound, the spindle base 28 is moved laterally so that the adjacent core 5 of the spindle shaft 1 faces the flyer 6. Then, the wire 21 between the winding end lead of the wound α winding coil and the nozzle 10 of the flyer 6 is drawn upward by a predetermined length by the wire drawing mechanism 34. Then, as described above, the winding core 5 is rotated, and the flyer 6 is rotated in the same direction as the winding core 5 at a double speed to manufacture a new α-winding coil.

  In this way, a predetermined number of α winding coils are connected and wound. The length of the connecting wire between each α-winding coil is regulated by the distance between the spindle shafts 1. However, when used as a multi-phase motor coil, it may be more convenient to have a predetermined length. There are merits depending on the application. In the above-described embodiment, the core 5 and the flyer 6 are rotated at the same time. However, the object of the present invention can be achieved even if the respective rotations are performed separately.

Next, as a fifth embodiment, a winding method for a multiple coil of a normal winding axially rotating coil will be described. In this case, the configuration of the apparatus is the same as that of the winding of the α winding coil.
The difference is that the flyer 6 is rotated in the same direction at the same speed in synchronization with the rotation of the core 5. By doing so, the wire 21 fed out from the flyer 6 exhibits the same action as that fixed to the end of the core 5. Therefore, the wire 21 drawn out from the wire drawing mechanism 34 can be wound around the winding core 5, and the axial coil is wound. In this case as well, if the spindle shaft 1 is not moved, a single-row multilayer coil is formed, and if the spindle shaft is moved in the axial direction, a multi-row multilayer shaft winding coil is wound. In this way, one shaft turning coil is manufactured.

  Next, as in the case of the α winding coil, the spindle base 28 is moved laterally so that the core 5 of the new spindle shaft 1 faces the flyer 6. Then, the wire rod 21 between the lead at the end of winding of the coil and the nozzle of the flyer 6 is drawn upward by a predetermined length by the wire rod drawing mechanism 34. Then, the flyer 6 is rotated in the same direction at the same speed in synchronization with the rotation of the core 5. Then, the wire 21 drawn out from the wire drawing mechanism 34 can be wound around the core 5, and the second connected shaft-turning coil is wound. Similarly, a predetermined number of axial coils are wound, and a predetermined number of axial coils are connected.

  Compared with a winding device using a series of spindle shafts 1, the size of the device is larger, but since the lead wire wound around the core 5 can be drawn out on both sides of the pulley 35 as a hook member, there is an advantage that the drawing height can be suppressed, In addition, there is an advantage that the work tact can be shortened because of less operation. Also in this case, for example, in the case where multiple coil shapes to be wound or coils having different diameters are mixed, it is possible to appropriately change the shape and diameter of the core 5 fixed to the spindle shaft.

  As described above, in any of the embodiments, the winding of the multiple α-winding coils and the multiple shaft-turning coils, which could not be realized in the past, can be realized by a winding machine having a simple structure, and its operation There is a big effect.

  The multiple α-winding coil and the shaft turning coil of the present invention can be used, for example, for various coils for electronic equipment, particularly for motor coils.
