Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an arbitrary position stopping device for multiple spindles, and particularly to an arbitrary position stopping device for multiple spindles used when winding a coil around a bobbin.

Generally, multiple spindles used for winding coils on bobbins are rotated by the same drive source via a transmission means such as a belt, but due to the outside of the drive system, the distance between the spindles is This results in a discrepancy. When accurately positioning multiple spindles with this misalignment, if the stop layer can be fixed at several fixed points due to factors such as the bobbin shape, a grooved cam is provided on each spindle to simultaneously position the stopper pin. This can be done by engaging. However, when it is desired to stop multiple spindles at arbitrary positions without mutual error, the above-described conventional mechanism cannot be employed.

Therefore, the present invention was made with attention to such points,
We provide a new arbitrary position stopping device for multiple spindles that can stop multiple spindles at any arbitrary position without mutual error. An insertion hole eccentric from the spindle rotation center is bored in the end face of the multi-spindle, and an insertion pin protruding from the end face of the multi-spindle rotates in the same circumferential locus as the insertion hole. a solid arm rotated by a pulse motor; an auxiliary arm that rotates with a 90 degree deviation from the solid arm; and the auxiliary arm and the solid arm are directed toward the end face of the multiple spindle. In addition to allowing hair to be removed freely,
The present invention resides in an arbitrary position stopping device for multiple spindles, characterized in that when the solid arm and the multiple spindles are connected, the drive of the pulse motor is disconnected.

Next, an example of the implementation of the present invention will be described with reference to the drawings.

A timing belt 2 driven by the same driving source is wound around each of the spindles 1, 1, and 2, so that each spindle 1,
Insertion holes 3, 3, . . . are bored at appropriate locations offset from the center in the end faces of 1. Also, this spindle 1

Both ends of this solid arm 4 are connected to eccentric positions of disks 7, 7 attached to rotating shafts 6, 6, and the other ends of the rotating shafts 6, 6 are also connected to eccentric positions of disks 8, 8. An auxiliary arm 9 is provided on the solid arm 4 and rotates with a 9-pitch offset. The solid arm 4 and the auxiliary arm 9, which are connected via the rotating shaft 6, are movable toward the end faces of the spindles 1, 1, . . . . still,

When the solid arm 4 and the auxiliary arm 9 are rotated independently, it becomes a driving source. The device according to the present invention is constructed as described above, and includes an insertion pin 5 protruding from the solid arm 4,
5... are inserted into the insertion holes 3, 3 drilled in the end faces of the spindles 1, 1..., each spindle 1, 1...

, 1... are insertion pins 5, 5, which are protruded from the solid arm.
The mutual errors disappear within the range of pitch deviation.

Further, the existence of the auxiliary arm 9 eliminates the dead center of rotation of the solid arm 4.

During high speed rotation, the solid arm 4 is connected to the spindles 1, 1

After confirming that the solid arm has reached a certain position, the solid arm approaches the spindles 1, 1..., the insertion pin 5 is inserted into the insertion hole 3, and the solid arm 4 and the spindles 1, 1... At this time, the solid arm 4 is separated from an independent drive source such as a pulse motor 10, and the spindle 1,

The arbitrary position stopping device for multiple spindles according to the present invention is constructed and operated as described above. Therefore, it is possible to stop the multi-spindle at any position without error, and the work of winding a coil around a bobbin becomes more efficient, and it is possible to prevent the production of defective products.

Thus, the present invention has excellent advantages,
The practical value of implementing the present invention is enormous.
