Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding holding device for an automatic winding machine, and is particularly applicable to a continuous automatic winding machine for a core with a multi-terminal. The present invention relates to a winding holding device for holding a winding (wire rod) in a stretched state.

In general, manually tying terminals and winding coils on a multi-terminal core requires a great deal of effort, and the accuracy is often unsatisfactory.

To solve this problem, a core with a terminal is held in a rotatable chuck, a wire feeding nozzle is rotated around the terminal of the core to wrap the terminal, and the chuck is rotated to wind the coil. An automatic winding machine has been developed to do this.

After the wire has been wrapped around the terminal, the wire is stretched in tension from the terminal and cut near the terminal by passing a cutting pin or lever across the wire.

In such a winding machine, a plurality of core chucks are attached to the outer periphery of a circular indexing table, and the table is rotated intermittently to automatically and continuously wind the core with multi-terminals while sequentially feeding them to the wire feeding nozzle. You can add lines.

In this case, in order to automatically continue winding a new core after winding one core and cutting the end of the winding, the tip of the cut wire must be passed through the wire feeding nozzle. It must be kept in an extended state.

The present invention is capable of holding the wire in a tensioned state from the terminal in order to cut the wire rod entwined with the terminal, and also allows the wire rod connected to the wire rod delivery nozzle after cutting to be prepared for the next winding operation. An object of the present invention is to provide a winding (wire) holding device for an automatic winding machine that can hold the wire in a stretched state.

A winding holding device according to the present invention includes a sliding rod supported on a bracket on a winding machine base so as to be slidable toward the center of the winding machine and relative to the bracket, and a winding of the sliding rod. A main drive gear with a shaft and a driven gear with a shaft are pivotally supported at the ends facing toward the center of the wire machine and mesh with each other, and the main drive gear with a shaft and the driven gear with a shaft each have a shaft portion fixed to the center of the gear. a winding holding lever rotatably supported on the tip of the sliding rod and having one end fixed to the shaft of the driven gear with a shaft; and a link mechanism connected to the shaft of the main driving gear with a shaft. and a crank mechanism that connects the link mechanism and the rotation morph, and the winding holding lever is configured to hold the winding wire together with the sliding rod when the crank mechanism is near the top dead center on the center side of the winding machine. The tip of the lever moves toward the center of the machine and rotates toward the center of the winding machine due to the rotational action of the main driving gear with the shaft and the driven gear with the shaft, and the crank mechanism moves to the bottom dead center on the outside of the winding machine. When it comes near the winding machine, it retreats together with the sliding rod to the outside of the winding machine, and due to the rotational action of the driven gear with the shaft and the driven gear with the shaft, the tip of the lever turns backwards to the outside of the winding machine, and the wire rod is removed. The device is characterized in that a wire rod connected to a delivery nozzle is locked, and the wire rod is clamped between the receiver on the bracket and the pin.

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

FIG. 1 is a schematic top view of a continuous automatic winding machine to which the present invention can be applied.

To briefly describe this continuous automatic winding machine, a circular indexing table 12 with a plurality of core chucks 13 attached thereto is provided on the top of a base 11 so as to rotate intermittently. , core supply device 14, core holding/correction device 15, twisting device 16, 17, 18, core extraction device 1
9 is placed.

On this base, a winding holding device 20 according to the present invention is installed between the tying devices 16 and 17, between the tying devices 17 and 18, and between the tying device 18 and the take-out device 19. .

21 and 22 are arranged respectively.

The multi-terminal core 23 is held by the chuck 13 at the position of the core supply device 14, and when it comes to the position of the tying device 16 as the indexing table 12 rotates, the tying device 16
The wire rod fed out from the wire rod delivery nozzle 24 is the core 23.
The coil is wound around the terminal of the coil.

At the start of the tying operation, the wire sent out from the nozzle 24 is manually stretched and held at an appropriate location, and when the coil formation (tying and coil winding) is completed, the wire at the beginning of tying is A cutting pin (not shown) provided in the tying device 16 is used to cut near the first tangled terminal.

In this state, the wire at the end of tying (this wire is connected to the wire feeding nozzle 24 of the tying device 16) is attached to another terminal of the same core, and this core is transferred to the next tying device 17. The table 12 is rotated to convey it to the position shown in FIG.

At this time, the winding holding device 20 according to the present invention disposed between the tying devices 16 and 17 holds the wire 25 at the end of tying, and the cutting device 107 provided in the tying device 17 cuts the wire. The lever 110 cuts the wire 25 near its terminal.

Since the wire rod 25 is held under tension between the twisted terminal and the winding holding device 20, the cut lever 11
0 can be easily cut by crossing this wire 25.

The wire rod 25 after cutting is held by the winding holding device 20,
From there, the wire feeding nozzle 2 of the tying device 16 is put into the stretched state.
It is connected to 4.

Therefore, when tying and coil winding the next new core using the tying device 16, it is necessary to manually pull the tip of the wire sent out from the nozzle 24, as in the operation start state of the winding machine described above. Instead, the new core can start working immediately.

Another wire is fed out from the wire feeding nozzle 26 of the tying device 17, and another coil is wound over the core on which the coil has been formed by the tying device 16.

In this case, the operation of the winding holding devices 21, 22 is the same as that of the winding holding device 20 described above.
