Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding machine, and more particularly to a winding machine for manufacturing an arcuate coil of a moving coil type arcuate motor.

An arc-shaped fixed core (stator), and a circular arc shape that engages with the outer periphery of the fixed core in a loosely fitted state and rotates about the center of the arc relative to the fixed core in response to an applied current. A so-called moving coil type circular arc motor including a coil (mover) has already been proposed by the applicant of this application and the applicant of Yen.

This movable coil type circular arc motor can reciprocate its circular arc coil at a highly accurate rotation angle within an angular range corresponding to the circular arc angle of the fixed iron core, and is used for exposure scanning of copying machines, facsimile machines, etc. It is suitable as a driving device for a swinging mirror, etc.

The object of the present invention is to provide a winding machine that can efficiently and precisely manufacture the circular arc coil of the above-mentioned moving coil type circular arc motor, especially the multilayer circular arc coil. According to the present invention, such an object includes: a bobbin installation member that supports an arc-shaped bobbin and is rotatable about the arc center of the arc-shaped bobbin; a rotating arm that rotates to feed out a wire; a drive device that rotationally drives the bobbin installation member and the rotation arm at a predetermined speed ratio; and a drive device that is provided between the drive device and the bobbin installation member. This is achieved by a winding machine for arc-shaped coils having a rotational direction changing device for changing the rotational direction of the rotational force transmitted to the bobbin installation member. The invention will be described in detail with reference to examples.

FIG. 1 attached herewith is a schematic diagram showing one embodiment of a winding machine for arcuate coils according to the present invention.

In this figure, reference numeral 1 indicates a bobbin installation member, and this bobbin installation member 1 is rotatable around a shaft 2, and has an arc-shaped bobbin support rod centered on the axis of the shaft 2. 3
It carries one end of the .

The bobbin support rod 3 is adapted to removably support an arcuate cylindrical bobbin 4 at its outer periphery.

A stopper plate 5 is removably attached to the other end, ie, the tip, of the bobbin support rod 3 with a screw 6.

Further, reference numeral 7 indicates a rotating arm, and this rotating arm 7 is connected to a shaft 8.
The bobbin 4 is supported by the bobbin support rod 3 and rotates around the axis of the bobbin 4 attached to the bobbin support rod 3.

The rotating arm 7 is supplied with a wire W from a spool (not shown), and is adapted to pull it out from its tip.

The shaft 8 fixedly supports a pulley 9.
is drivingly connected via an endless belt 13 to a pulley 12 fixedly supported on a drive shaft 10.

The drive shaft 10 has a hand bundle 11 at one end thereof, and is manually driven to rotate in the direction of the arrow.

Further, the drive shaft 10 fixedly supports a pulley 14, and this pulley 14 is interlocked and connected to a pulley 16 fixed to an intermediate shaft 15 via an endless belt 17. The transmitted rotational force is transmitted to a worm shaft 19 via a rotation direction switching device 18. The worm shaft 19 has a worm wheel 21 that engages with a worm wheel 20 attached to the shaft 2. There is.

As clearly shown in FIGS. 2 and 3, the rotational direction changing device 18 includes an input gear 22 fixedly supported on the intermediate shaft 15 and an output gear 23 fixedly supported on the worm shaft 19. , the input gear 22 and the output gear 2
2 and 3, which are disposed in meshing relationship with each other and rotatably supported on the switching lever 24 by shafts 25 and 26, respectively;
When the switching lever 24 is tilted in the direction indicated by A in the figure, the first intermediate gear 27 meshes with the input gear 22, thereby transferring the rotational force of the input gear 220 to the first intermediate gear. 27 to the output gear 23, and when the switching lever 24 is tilted in the direction indicated by B in the figure, the second intermediate gear 28 transfers to the input gear 22.
By meshing with the input gear 220, the rotational force of the input gear 220 is transmitted to the output gear 23 via the second intermediate gear 28 and the first intermediate gear 27.

Therefore, in this case, when the switching lever 24 is tilted in the direction indicated by A in the figure, the intermediate shaft 15 and the worm shaft 19 rotate in the same direction, whereas the switching lever 24 rotates in the same direction. When the worm shaft 19 is tilted in the direction indicated by B in the figure, the worm shaft 19 rotates in a direction opposite to the direction of rotation of the intermediate shaft 15.

When winding an arc-shaped coil using a winding machine configured as described above, first the bobbin 4 is attached to the bobbin support rod 3 of the bobbin installation member 1, and then the bobbin 4 is attached to the bobbin support rod 3 of the bobbin installation member 1. One end of the wire rod W is locked to a wire fastener (not shown) provided on the bobbin installation member 1.

Next, the hand bundle 11 is used to rotate the drive shaft 12 in the direction of the arrow.

Then, the rotary arm 7 rotates around the axis of the bobbin 4, and the wire W is drawn out from the tip of the rotary arm 7 and wound around the outer circumference of the bobbin 4, and the bobbin installation member 1 is rotated accordingly. rotates around the shaft 2, that is, around the arc center of the bobbin 4, and thereby the winding of the wire rod W around the bobbin 4 progresses.

At this time, the switching lever 24 is moved to A as shown in FIG.
If the intermediate shaft 15 and the worm shaft 19 rotate in the same direction, the bobbin installation member 1 will move in the direction shown by the arrow in the first position as the hand bundle 11 rotates in the direction of the arrow. If the switching lever 24 is tilted in the direction indicated by B as shown in FIG. 3, the worm shaft 19 will rotate the intermediate shaft 15. By rotating in the opposite direction, the bobbin installation member 1 rotates clockwise as viewed in FIG. 1 as the child bundle 11 rotates in the direction of the arrow.

Therefore, once the winding of the wire W has progressed to the end of the bobbin 4, the switching lever 24 may be operated to switch the direction of rotation of the bobbin installation member 1.

As a result, a multi-layered cylindrical coil having a predetermined winding pitch is obtained.

In a moving coil type motor, the larger the number of winding layers of the moving coil, the higher the output of the motor.

This not only contributes to improved performance and higher precision of the motor, but also reduces the amount of heat generated by the coil portion since the drive current is small.

As described above, according to the winding machine of the present invention, the rotary arm 7 that unwinds the wire rod and the bobbin installation member 1 that feeds the bobbin 4 are driven in synchronization with each other, and the rotational direction of the bobbin installation member is It will be understood that by arbitrarily switching the direction of rotation of the rotary arm 70 using the rotation direction switching device 18, it is possible to repeatedly manufacture a high-quality multilayer arc-shaped coil having a predetermined constant pitch.

In the above, the present invention has been described in detail with reference to specific embodiments, but the present invention is not limited thereto, and those skilled in the art will appreciate that various embodiments are possible within the scope of the present invention. It would be obvious for
