SOLUTION: This winding machine is a winding machine, which performs winding of an air-core coil and transfer to the next process and is constituted of an external actuator 7, in which a compression spring 6 is installed at the tip, a winding jig 1 performing rotating operation, and a chuck 2 which is installed on the outer periphery of the winding jig 1 and can be opened and closed with the external actuator 7. The winding machine is equipped with a chuck mechanism, which clamps a winding start wire of the air-core coil by closing the chuck 2 and clamps a winding end wire of the air-core coil with the chuck 2 and the compression spring 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air core coil winding machine used for an IC card, and more particularly, to a winding start wire and a winding end wire when the air core coil is wound and then transferred to the next process. The present invention relates to a chuck mechanism that can easily carry out delivery while maintaining the tension of the chuck.

[0002]

2. Description of the Related Art Conventionally, when winding an air-core coil, terminal processing for maintaining the shape of the coil is performed by turning a nozzle passing through a wire and performing lashing on a fixed pin or the like. Has been adopted.

Conventionally, however, the unit for supporting the nozzle for performing the kerving process is a device having a swivel function, and thus tends to be complicated, and has a drawback that the time required for the process is long.

Conventionally, when transferring a coil after winding, the held winding start line and winding end line are merely released from holding, so that there is a disadvantage that the shape is disturbed. In addition, at the time of transfer, there is no easy-to-release lashing taking into account delivery.

[0005]

Therefore, the present invention has a simple structure and, when transferring an air-core coil after winding to the next step, does not disturb the shape of the coil, and starts winding and winding. An object of the present invention is to provide a winding machine provided with a chuck mechanism that can easily transfer while maintaining the tension of the end line.

[0006]

In order to solve the above-mentioned problems, a winding machine according to the present invention is provided with a chuck which can be opened and closed with a simple structure on the outer periphery of a winding jig to form a winding start line and a winding end line. The grip and the positioning can be quickly performed, and the coil can be easily released without disturbing the shape of the coil, so that the transfer to the next process can be easily performed.

That is, according to the present invention, there is provided a winding machine for winding an air-core coil and transferring the air-core coil to a next step. A chuck provided on the outer periphery of the winding jig and capable of being opened and closed by the external actuator, gripping a winding start line of the air core coil by closing the chuck, and setting a winding end line of the air core coil. A winding machine comprising a chuck mechanism for holding the chuck by the chuck and the compression spring.

The winding machine of the present invention has the following effects by adopting the above configuration. a) Even when the winding operation is completed, it is possible to hold the state of gripping and positioning of the winding start line and the winding end line. b) Delivery to the next step becomes easy, and the tension of the winding start wire and the winding end wire after the delivery can be easily maintained. c) The elimination of the ganging process simplifies the winding operation and shortens the winding time.

Embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a chuck mechanism of a winding machine according to an embodiment of the present invention. FIG. 2 is a perspective view showing a state in which the winding start line is gripped and positioned in the winding machine according to the embodiment of the present invention. FIG. 3 is a perspective view showing a state in which the winding start line and the winding end line are gripped and positioned in the winding machine according to one embodiment of the present invention.

As shown in FIG. 1, a chuck 2 which is urged by a compression spring 3 and has a rotation support is provided on the outer periphery of a winding jig 1 which performs a rotating motion. Guide pins 4 are provided on the chuck 2. Further, the chuck 2 can be opened and closed by an external actuator 7. A roller 5 is provided at the tip of the external actuator 7. By the movement of the external actuator 7, the guide pin 4 comes into contact with the roller 5, and a downward force acts on the guide pin 4, whereby the chuck 2 opens.

As shown in FIG. 2, the gripping of the winding start wire 8 passing through the trajectory of the two-dot chain line is performed by opening the chuck 2 in advance, and after the winding start wire 8 has passed through the chuck 2, the external actuator 7 is held. Is performed by returning The gripping winding start wire 8 rotates the winding jig 1 while maintaining the state.
Wound by Therefore, since the opening and closing of the chuck 2 is linked to the operation of the external actuator 7, the winding start wire can be quickly grasped and positioned with a simple structure.

Next, as shown in FIG. 3, the compression spring 6 at the distal end of the external actuator 7 stops the rotation of the winding jig 1 when the side surface of the distal end of the chuck 2 crosses the traveling direction of the external actuator 7. Then, the external actuator 7 moves and comes into contact with the chuck 2.

That is, since the winding end line 9 passes through the trajectory of the two-dot chain line after the rotation of the winding jig 1, the chuck 2
Through the side of Then, by moving the external actuator 7, the winding end line 9 passing through the chuck 2 is moved.
Can be gripped and positioned.

Further, the chuck 2 and the external actuator 7 can release the winding end line 8 and the winding end line 9 instantaneously, so that the delivery to the next step can be facilitated.

[0016]

As described above, according to the present invention, in addition to the simple structure, when the air-core coil after winding is transferred to the next step, the winding start wire and the winding can be formed without disturbing the shape of the coil. It was possible to provide a winding machine having a chuck mechanism capable of easily transferring while maintaining the tension of the end line.
