BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for automatically winding a transformer, a coil and the like, and more particularly, to attaching and holding a bobbin such as a transformer and a coil on which a winding is applied. And a bobbin holding section of a winding machine for removal.

[0002]

2. Description of the Related Art Conventionally, this type of winding machine includes a spindle unit that rotates while holding a bobbin to which a winding is applied, and a spindle unit that rotates.
It comprises a nozzle moving unit or the like for guiding a wire of a winding whose movement is controlled in the dimensional direction, and is configured to automatically wind a bobbin. In mounting a bobbin having a hollow portion on a winding machine, a shaft connected to a rotating spindle unit is inserted into the hollow portion of the bobbin, and the bobbin is mounted on the winding machine. In the case of a bobbin having no hollow portion, for example, having a flat shape, as shown in FIG. 2, the upper holding pawl 11 and the lower holding pawl 11 are interposed via a compression coil spring 10 disposed between the upper holding pawl 11 and the lower holding pawl 9. With the hinge pin 8 provided through the support 7 on each side of the holding pawl 9 as a fulcrum, the force point position of the push plate 12 fixed above the upper holding pawl 11 is applied or released by applying an external force in the direction of arrow 14. The bobbin 6 is attached, held, and removed by the bobbin holding portion in which the upper presser pawl 11 swings up and down. The lower presser pawl 9 is connected to the rotating spindle unit 13, and the wire rod 3 wound around the bobbin 6
Is supported by a support 4 of a nozzle moving unit that moves in a three-dimensional direction.

[0003]

[Problems to be Solved by the Invention] When the bobbin is attached to the winding machine by the bobbin holding portion of the conventional winding machine, the force point of the push plate is pushed down by the operator himself, and the upper presser pawl is raised. Attach the bobbin to the specified position of the lower retainer using the pin terminal etc. attached to the bobbin. Next, after the bobbin is attached, release the finger from the push plate, hold the bobbin with the upper retainer by the force of the compression coil spring, and hold the bobbin with the upper retainer. The nozzle moving unit is moved to move the wire around the bobbin. Removal of the bobbin after the winding is completed is similarly performed by pushing down the push plate with a finger. Therefore, there is a problem that the finger is hurt because the pressing plate is pressed down with a finger repeatedly for mounting and removing the bobbin. Further, in a winding machine in which a large number of spindle units for mounting the bobbin are installed, there is a problem that it takes a long time to mount and remove the bobbin.

According to the present invention, a bobbin for applying a winding to a winding machine that automatically winds the bobbin is mechanically mounted in a short time without using the force of an operator's finger for mounting and removing the bobbin. It is intended to provide a detachable winding machine.

[0005]

Means for Solving the Problems To achieve the above object, the winding machine of the present invention, after the winding on the bobbin is completed,
When the nozzle moving unit for guiding the wire of the winding moves in the three-dimensional direction for the next operation, the position where the point of force of the push plate fixed to the upper presser pawl holding the bobbin of the bobbin holding section is pressed down. , A push pin having a cam follower at a lower end thereof is attached to a nozzle support of a nozzle moving unit in a direction perpendicular to the push plate.

That is, according to the present invention, a nozzle moving unit having a nozzle for guiding a wire of a winding is moved in a three-dimensional direction in synchronization with the rotation of a spindle unit which rotates while holding a bobbin on which a winding is applied. In the winding machine that moves and automatically winds on the bobbin, the bobbin holding portion that holds the bobbin is integrated with the support that supports the nozzle of the nozzle moving unit, with the hinge pin as the fulcrum via a compression coil spring, A winding machine characterized in that a push pin having a rotating cam follower at a lower end thereof is attached to push down a point of force of a push plate fixed to an upper side of an upper presser pawl swinging up and down.

[0007]

The bobbin is attached to and detached from the winding machine constructed as described above according to the present invention. The push pin attached to the nozzle support of the nozzle moving unit that moves in the three-dimensional direction is mechanically pushed. Since the power point of the plate is pushed down, the tip for holding the bobbin of the upper presser is automatically raised with the hinge pin as a fulcrum via a spring, and the bobbin can be attached and detached. In addition, even when a large number of spindle units that rotate while holding the bobbin are installed, in the conventional winding machine, the work of attaching and removing the bobbin was performed with the other hand while pushing down the push plate with one hand. However, in the winding machine of the present invention, since the push pin pushes down the push plate, the bobbin can be attached and detached with both hands, so that the work becomes easy and can be performed in a short time. Also, since the lower end of the push pin has a cam follower, when the push pin contacts the push plate,
Since the cam follower rotates and pushes down the power point of the push plate, there is almost no contact wear between the push pin and the push plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a partial side view showing a state in which a push pin 1 of a winding machine of the present invention pushes down a push plate 12.
In FIG. 1, a support 4 supporting a nozzle 5 for guiding a wire 3 of a winding of a nozzle moving unit that moves in a three-dimensional direction of a winding machine has a cam follower 2 rotating to a lower end.
Is attached. The push pin 1
Is attached to the support 4 at a position where the support 4 of the nozzle 5 of the nozzle moving unit is moved for the end processing operation of the wire 3 after the winding on the bobbin 6 is completed. When the lever is lowered, the cam follower 2 at the tip of the push pin 1 attached to the support 4 is positioned to push down the vicinity of the point of force of the push plate 12 fixed above the upper presser pawl 11 holding the bobbin 6. Attached to. Further, the bobbin holding portion of the winding machine that holds the bobbin 6 is moved upward through a compression coil spring 10 disposed between the lower presser pawl 9 and the upper presser pawl 11 that are connected to the rotating spindle unit 13. The upper presser pawl 11 swings up and down and is fixed to the upper presser pawl 11 with a hinge pin 8 provided through a support 7 provided upright on each side of the presser pawl 11 and the lower presser pawl 9. When the push pin 1 is separated from the push plate 12, the upper presser pawl 11 holds the bobbin 6. In addition, since the nozzle 5 of the nozzle moving unit is disposed on the back side of the push pin 1, even if the push pin 1 is lowered, it does not contact the upper presser pawl 11.

[0009]

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects. When attaching and detaching the bobbin to and from the winding machine, in the conventional winding machine, the push plate of the bobbin holding unit was pressed down by the force of the operator's finger, but the nozzle of the unit that moves in the three-dimensional direction according to the present invention. By attaching the push pin to the support, the push pin mechanically pushes down the point of force of the push plate, eliminating the need to push down the push plate with fingers, and the bobbin can be attached and removed with both hands. It is possible to provide an inexpensive winding machine that can be easily attached and detached in a short time and that does not use a complicated mechanism or actuator for pushing down the force of the push plate.
