Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for winding a wire for coil formation around a multi-pole armature.

[0002]

2. Description of the Related Art Conventionally, a winding machine has been widely used for winding a wire for forming a coil around a pole (winding core) of a multipolar armature. In order to improve the performance of an armature such as a motor with a limited size, it is necessary for a winding machine to have as many windings as possible in the limited winding space of a multi-pole armature. You. For this purpose, so-called aligned winding, in which wires adjacent to the pole are aligned and wound without gaps, is effective.

In such a case, the motor for driving the nozzle from which the wire is fed and the motor for indexing and rotating the multipole armature are individually driven, and the nozzle and the multipole armature move relatively. The winding to the pole (core) can be wound in a short time without any gap. That is, the nozzle moves up and down, and the multi-pole armature rotates around the center thereof, whereby the wire is wound around the pole.

[0004] In the above-described motor, a high-speed rotation can shorten the winding time, so that a large-sized motor is used. Further, by using a timing belt or the like as the drive transmission device, it is possible to move the nozzle and the multi-pole armature at high speed.

[0005] In the winding process, a part of the wire connecting the poles (cores) is locked as an intermediate wire called a tap wire at a locking portion at a distance from the multipolar armature. . Then, the start line and the finish line are also locked by the locking portions at a distance from the multipolar armature.

[0006]

However, in such a winding machine, when reciprocating a short distance in a short period of time, even if the moving body is relatively light, the inertia force of the moving body is increased. After going a little too far
A phenomenon of returning to a desired position and stopping (this is called overshoot) occurs. In order to suppress this phenomenon, it is necessary to select a relatively large motor. However, as the motor becomes larger, its own inertial force increases, and it becomes difficult to suppress overshoot. Also, the timing belt driving device is inferior in rigidity as compared with a moving device driven by a ball screw or a gear, so that an overshoot in which positioning at the time of stopping is more difficult occurs. If positioning is not possible, the devices may come into contact and be damaged.

Also, in the winding step, if the locking portions for locking the tap wire, the start wire and the finish wire cannot be easily released, it takes more time to manufacture one multi-pole armature. , The production number cannot be increased.

SUMMARY OF THE INVENTION An object of the present invention is to suppress overshoot generated when a nozzle or a multi-pole armature moves, and to easily drive a driving device capable of accurate positioning, and to easily lock a tap wire, a start wire and a finish wire. An object of the present invention is to provide a winding machine having a device that can be released.

[0009]

In order to solve the above-mentioned problems, a first configuration of a winding machine according to the present invention comprises a wire rod for forming a coil guided by a wire rod guiding mechanism. A winding machine for winding a wire rod to a position to be wound, and one or more driving devices provided to relatively move the nozzle and the winding core. Is characterized in that a drive resistance mechanism is added.

In the winding machine, the driving device is a rotary driving mechanism, the driving resistance mechanism is an electromagnetic friction resistance mechanism, and the driving resistance mechanism always adds a resistance to a shaft rotated by the driving device during driving. It is characterized by doing.

In the winding machine having such a configuration, the driving device is a rotary driving mechanism, and an electromagnetic friction resistance mechanism, which is a driving resistance mechanism, is attached to the rotating shaft. That is, the electromagnetic friction resistance mechanism is provided to reduce the inertial force of the rotating shaft. As a result, overshoot is reduced, and accurate positioning of the nozzle and the core becomes possible.

A winding machine for winding a wire for coil formation guided by a wire guide mechanism around a winding core, wherein a nozzle for guiding the wire to a position where winding is to be performed, and a nozzle and the winding core are relatively positioned. Comprising one or more first driving devices provided for moving the first driving device, wherein the first driving device includes another second driving device that drives in the same or opposite direction to the driving direction. Features.

In the winding machine, the first driving device is a rotation driving mechanism, the second driving device is a rotation driving mechanism, and the second driving device is connected to a driving shaft driven by the first driving device. It is characterized in that the drive shaft is rotated in the same or opposite rotation direction as the rotation direction.

In the winding machine, the second drive unit rotates in the same rotation direction as the drive shaft at the start of rotation of the drive shaft and at the time of steady rotation. It is characterized by trying to rotate in the opposite rotation direction.

In the winding machine having such a configuration, the second driving device connected to the driving shaft driven by the first driving device has the same rotation direction as the driving shaft at the start of rotation of the driving shaft and at the time of steady rotation. The drive shaft is provided so as to rotate in a rotation direction opposite to that of the drive shaft at the time of deceleration rotation of the drive shaft and immediately before stopping. In other words, when the drive shaft starts its rotation and at the time of steady rotation, the second drive device supports the drive force of the drive shaft, that is, rotates in the same rotational direction as the drive shaft so as not to lose the inertial force of the drive shaft. . In addition, the second drive device is provided to rotate in a direction opposite to the drive shaft in order to reduce the inertial force of the drive shaft during the deceleration rotation of the drive shaft and immediately before the stop. This makes it possible to assist the first driving device at the beginning of the movement of the nozzle or the core, and to suppress overshoot at the end of the movement.

In the winding machine, the first drive device is a rotary drive mechanism, the second drive device is a rotary drive mechanism, and the second drive device is connected to the drive shaft and has the same rotation direction as the drive shaft. It is characterized in that it rotates only in the rotation direction.

In the winding machine having such a configuration, the first drive device and the second drive device are substantially the same,
Rotate the drive shaft in the same direction. That is, since two relatively small driving devices are used without using a large driving device, it is possible to reduce the inertial force of the rotating unit and the driving shaft of the driving device, and to reduce rotation delay and overshoot.

A winding machine for winding a wire for coil formation guided by a wire guide mechanism around a core, the wire holding the wire when the wire is wound around the core and fixing the core. In the holding tool of the holding device, the holding tool is provided with a hook member, and the hook member holds a wire and / or a start wire and / or a finish wire between the winding cores in the winding, and when the winding is completed, the hook member is formed. Is characterized in that the holding of the wire and / or the start wire and / or the finish wire between the winding cores in the winding is released by inclining.

Further, the hook member is characterized in that it is rotated about a shaft supporting the hook member and tilts when the holding member expands and contracts.

Further, when a force is applied against the urging force of the elastic member in the extending direction of the holding member, the hook member is horizontally moved about the axis supporting itself by the cam portion of the holding member. When the force is maintained and the force is released, the interference of the cam portion is eliminated, and the hook member is inclined about the axis supporting itself.

In the winding machine having such a configuration, the wire between the winding cores is held by the hook member at the beginning of the winding, and when the winding is completed, the hook member is inclined by the cam portion to release the holding of the wire. You. Thereby, since the wire between the cores is fixed in the winding, the nozzle or the like does not get caught. In addition, since the wire between the cores can be released at once in a short time after completion of the winding, the time for removing the multipole armature can be reduced, and the manufacturing time per piece can be reduced. Increases efficiency.

A winding machine for winding a wire for forming a coil guided by a wire guide mechanism around a core, which holds a start line and a finish line of the core when winding the wire around the core. In the wire clamp device of the wire holding device, the wire clamp device includes a cutting section for cutting a finish wire.

Further, the cutting section cuts the finish line and, at the same time, holds the start line of the next winding.

The cutting section includes a cutter for cutting a finish line and a clamp for holding a start line of the next winding, and the cutter and the clamp are arranged adjacent to each other, and are both line clamped by the urging force of an elastic member. After being pushed out toward the receiving part attached to the device, the tip of the cutter and the clamp contact the receiving part and hold the wire on the start line side, only the cutter passes through the side surface of the receiving part and removes the wire on the finish line side. It is characterized by cutting.

In the winding machine having such a configuration, at the end of winding, the finish line is cut by the cutter after the next start line is held by the clamp. As a result, the control of the wire is facilitated, and the time until the next winding is shortened, so that the production efficiency is improved.

However, in the winding machine of the present invention, overshoot is suppressed because positioning can be accurately performed at the time of stop in position movement.

Next, the holding member 9 of the wire rod holding device of the winding machine according to the present invention will be described. FIG. 11A is a front sectional view of the holding member 9, and FIG. 11B is a side sectional view of the holding member 9.

Next, the winding step will be described. As shown in FIG. 11, the start line S is held by the holding portion 45a of the hook member 45, and is wound around the multi-pole armature 6 by moving the nozzle 3 (see FIG. 5). At this time, between the cores C (FIG. 7)
) Is also locked to the hook member 45. During this time, the cylinder shaft 7a of the cylinder 7 (see FIG. 5) is in an extended state so as to press the multipolar armature 6. Therefore, the hook member 45 is maintained in the horizontal direction by the curved surface portion 45b being in contact with the convex portion 47a. When the winding is completed, the finish line F is also held by the holding portion 45a of the hook member 45.

When the winding is completed as shown in FIG. 12, the cylinder 7 opens the multipole armature 6. At the same time, the upper holding member 46 moves in the ascending direction by the urging force of the elastic member 51. Then, the convex portion 47a of the lower presser 47 that supports the hook member 45 in the horizontal direction moves away from the upper presser 46, so that the hook member 45 slides on the curved surface 45b due to its own weight. While starting to incline downward from the horizontal around the axis 48. As a result, the start line S (see FIG. 11) and the finish line F (see FIG. 11)

A shaft 59 is fixed to the clamp base 55, and a cylindrical clamp 53 is attached to the outer periphery of the shaft 59 so as to be movable in the shaft 59 direction. A receiving portion 60 for limiting the movement of the clamp 53 is attached to the other end of the shaft 59. Further, a first elastic member 56 is provided between the clamp base 55 and the clamp 53 so as to urge the clamp 53 toward the receiving portion 60. The cylinder 58 has its cylinder shaft 5
A cylindrical member 61 is attached to 8a, and a cutter arm 62 is fixed to the other end with a screw or the like. The cutter arm 62 is attached so as to engage with a guide surface 53a on the side surface of the clamp 53. The cutter 54 is attached to the cutter arm 62 and is disposed on the side of the clamp 53. Further, the cutter arm 62 is urged by the second elastic member 57 in a direction opposite to the cylinder 58, that is, in a direction in which the cutter 54 is pushed out. Here, the guide surface 53a includes a stopper 53b for stopping the cutter arm 62 in order to limit the amount of movement of the cutter 54. Further, the guide surface 53a is provided with a pressing portion 53c for suppressing the movement of the clamp 53 due to the urging force of the first elastic member 56 by the cutter arm 62.

The operation steps of the wire clamping device 8 will be described.
As shown in FIGS. 13A and 13B, when the winding of the wire W is completed, the clamp 53 and the receiving portion 60 are moved by the nozzle driving motor 5 (see FIG. 5) and the lateral movement motor 21 (see FIG. 5). It is arranged so as to pass from the cutter 54 to the clamp 53 side. At this stage, the clamp 53 urged by the first elastic member 56 cannot move in the direction of the receiving portion 60 by its own pressing portion 53c and the cutter arm 62.

Thereafter, the cylinder 58 is moved to the cylinder shaft 58a.
Extrude. The cylinder shaft 58a pushes the cutter arm 62 through the cylindrical member 61 to the receiving portion 60 side together with the urging force of the second elastic member 57. At the same time, the clamp 53 is also pushed out toward the receiving portion 60 by the urging force of the first elastic member 56. The wire W is sandwiched and held between the clamp 53 and the receiving portion 60.

Thereafter, as shown in FIGS. 14 (a) and 14 (b), the clamp 53 is stopped by the receiving portion 60, but the cutter 54 moves the cylinder until the cutter arm 62 comes into contact with the stopping portion 53b of the clamp 53. The urging force of the second elastic member 58 and the second elastic member 57 moves the receiving part 60.
At this time, the wire W (see FIG. 13) sandwiched between the clamp 53 and the receiving portion 60 is cut by the cutter 54 passing through the side surface of the clamp 53. The wire held by the clamp 53 becomes the start line S of the next winding, and the wire not held becomes the finish wire F of the finished winding.
