Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer rotor type winding machine for winding by a relative movement between a nozzle for supplying a wire and a laminated core having a plurality of slots in its outer peripheral portion.

[0002]

2. Description of the Related Art Conventionally, an outer rotor type winding machine of this type reciprocates in the horizontal axis direction with a nozzle fixed in the vertical position, and correspondingly a laminated core (hereinafter referred to as "workpiece"). Was rotating and moving up and down to perform winding.

[0003]

However, in such a conventional outer rotor type winding machine, since the work moves up and down during winding, there are many problems as follows.

That is, since the work is stationary only by the force of the motor, the processing of the wire at the beginning and end of winding and the processing of the crossover wire etc. at the time of transition from the previous winding to the next winding are performed. When a wire is guided, a hook for hooking the wire is crushed, or a guide, a pusher, or a cutter for cutting the wire comes into contact with the work, the work may move easily. In order to avoid this, a stopper that stops the movement of the work is required. Moreover, since the height of the workpiece and the height of the nozzle are not always the same, the stoppers must be provided at multiple places, and it is almost impossible to move these stoppers each time when adjusting the height of the workpiece. there were.

In order to wind a plurality of works at the same time, it is necessary to rotate a plurality of main shafts supporting the works, and to move the main shafts supporting the works, respectively. Was increased and it was difficult to increase the speed.

Further, a swinging rotation mechanism for driving the work in a rotating direction and a vertical direction, a vertical slide mechanism of the same power source as this, and a variable stroke mechanism for changing its vertical stroke are provided in the oil tank for speeding up. Since it is hermetically sealed and lubricated, it is necessary to work in the oil tank to change the vertical stroke of the work in response to changes in the product thickness.

The present invention has been made in view of the above points, and it is possible to easily perform the line processing at the time of winding, to increase the speed in the case of multiple connections, and to easily deal with the change in the product stack thickness. An object is to provide an outer rotor type winding machine.

[0008]

In order to achieve the above object, the present invention provides an outer rotor type winding machine for winding by a relative movement between a nozzle for supplying a wire and a laminated core having a plurality of slots in its outer peripheral portion. In the outer rotor winding machine, the nozzle is linearly moved in the horizontal axis direction and the vertical direction, and the laminated core is rotated around the center line to perform winding. In the outer rotor type winding machine, it is preferable that the axial driving means and the vertical driving means of the nozzle are provided independently of each other.

[0009]

By configuring the outer rotor type winding machine according to the present invention as described above, since the work to be wound (stratified iron core) is fixed in the vertical position only by rotating, various wire treatments can be performed. , The structure of the drive unit of the work is simplified, the inertia is significantly reduced, and the winding speed can be increased.

Further, if the respective driving means in the axial direction and the vertical direction of the nozzle are independently provided, a vertical stroke varying mechanism of the nozzle similar to the conventional stroke varying mechanism of the work can be provided outside the oil tank. This makes it possible to remarkably facilitate the stroke adjustment of the nozzle when the stack thickness of the work is changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a perspective view showing an overall configuration of an embodiment of the present invention, and FIG. 2 is a perspective view showing a state in which a power transmission portion to each of the work rotation and nozzle up / down cam units is viewed from the rear side, FIG. 3 and FIG. 4 are enlarged perspective views of essential parts showing a part of FIG. 1 in an enlarged manner, and FIG. 5 is a plan view of essential parts showing a front-back driving mechanism of the nozzle.

This outer rotor type winding machine is a double winding machine capable of winding two workpieces at the same time, and the respective configurations are exactly the same for both, so here, except for a part thereof, Only one of them will be illustrated and described.

The main power source of this winding machine is a main motor 2 mounted on a lower substrate 1 as shown in FIG. 2, and its rotation is fixed on an upper substrate 3 via two sets of belt devices. The output shafts 4a and 5a are reciprocally rotated at an angle of 45 ° to the installed work rotation cam unit 4 and the nozzle up / down cam unit 5 at the same time.

Output shaft 4a of the cam unit 4 for rotating the workpiece
As shown in FIG. 3, the reciprocating rotation of the slide guide 6 is integrated with the output shaft 4a, the connecting shafts 7 and 7 which are displaceable in the slide guide 6 in the longitudinal direction thereof, and the turnbuckle 8 for length adjustment. , 8 are transmitted to the arms 10 and 10 via rods 9 and 9, and these arms 10 and 10 are reciprocally rotated. In addition, adjustment of the rotation angle of the arms 10 and 10
This is performed by changing the positions of the connecting shafts 7 and 7 by the feed screws 6a and 6a provided on the slide guide 6 and rotating the turn buckles 8 and 8 to change the total length of the rods 9 and 9.

The rotation of the arms 10 and 10 is transmitted to the main shafts 12 and 12 that rotate in the rotational direction by spline connection or the like to the clutch member 11b by connecting the clutch members 11a and 11b constituting the clutch 11, and at the time of winding the main shaft. While the works WK, WK fixed on the clutch 12, 12 are reciprocally rotated by a predetermined angle, the clutch members 11b, 1
By coupling 1c, the rotation of the index rotation pulse motor 13 fixedly mounted on the lower substrate 1 is controlled by the main shaft 12,
12, the workpieces WK and WK are index-rotated by a predetermined angle at the time of crossover from one winding to the next. The clutch 11 is connected / disconnected by swinging the arm 15 in the up / down direction by the solenoid 14 provided separately and moving the clutch member 11b up / down.

On the other hand, the reciprocating rotation of the output shaft 5a of the nozzle up / down cam unit 5 is moved up and down a slider 16 shown in FIG. Each arm 17 is attached, and the tip of the arm 17 is held by a roller follower mechanism (not shown) provided on the holder 18, and each holder 1
The vertical movement of 8 is transmitted to the nozzle holder 20 through the guide rods 19 and 19 to move the nozzle 21 up and down. 1 and 4, only two sets of the holder 18, the nozzle holder 20, and the nozzle 21 are shown for simplification of the drawings, but actually, three heads are provided for each head as shown in FIG. is there.

The forward and backward movement of the nozzle 21 in the axial direction is as shown in FIG.
As shown in FIG. 3, the ball screw 23 is rotated by the pulse motor 22 for front and rear of the nozzle to move the bracket 24 forward and backward. That is, the nozzle holder 20a located at the center in FIG. 5 is provided on the slider 25a which is integral with the bracket 24 so as to move together with the bracket 24, and the left and right nozzle holders 20b and 20c are fixed by the wing bar 26 fixed to the slider 25a. Each slider 25b, 25c
It is moved back and forth through each cam follower 27 composed of a roller pair provided above.

At this time, if the angle θ formed by the nozzles 21b and 21c with the center nozzle 21a is, for example, 20 °, the angle formed by the horizontal direction of both wings of the wing bar 26 is θ / 2, that is, 10 °. Each nozzle 21a, 21
The same feed amount can be given to b and 21c.

Next, the operation of the embodiment having the above structure will be described. When the solenoid 14 is excited from the state shown in FIGS. 1 and 3 and the arm 15 is swung in the up-and-down direction with the center part as a fulcrum, the clutch member 11b rises via the cam follower provided at one end thereof and is disengaged from the clutch member 11c. The clutch member 11a is engaged with the clutch member 11a, the rotation of which is transmitted to the main shaft 12 via the clutch member 11b, and the workpiece WK supported on the main shaft 12 can be reciprocally rotated by the workpiece rotation cam unit 4. Becomes

When the main motor 2 shown in FIG. 2 is started in this state, the output shaft 4 of the work rotating cam unit 4 is driven.
a and the output shaft 5a of the nozzle up / down cam unit 5 both start reciprocating rotation. The reciprocal rotation of the output shaft 4a is transmitted to the arm 10 via the slide guide 6, the connecting shaft 7, and the rod 9, and the main shaft 12 and the work WK supported thereby are reciprocally rotated by a predetermined angle via the clutch 11.

The reciprocating rotation of the output shaft 5a is converted into the vertical movement of the slider 16, and an arm 17 integrated with the slider 16 and a holder 18 and a guide rod 19 which move vertically with the arm 17 together with the nozzle holder. 20 and the nozzle 21 are moved up and down.

As described above, by the reciprocating rotation of the work W and the vertical movement of the nozzle 21 synchronized with the reciprocating rotation, the portion of FIG.
Workpiece WK through the steps shown in (b), (c), (d), and (e)
T-shaped spokes WK 'formed between each slot of the
The wire W can be wound around. And the nozzle 2
By moving 1 up and down and back and forth simultaneously, arm 1
7 and the holder 18 slide in the horizontal direction, so that a large amount of wires can be aligned and wound along the radial direction of the spoke portion WK '. In this embodiment, one work WK
On the other hand, since it is possible to perform winding with three nozzles and two nozzles are provided in series, the work efficiency of the winding can be improved.

Next, when the previous winding ends and the next winding is completed, the solenoid 14 is de-excited and its actuator is caused to project by its own spring force.
The arm 15 rotates clockwise, the clutch member 11b disengages from the clutch member 11a, and engages with the clutch member 11c, resulting in the state shown in FIGS. 1 and 3. As a result, the rotation of the arm 10 is not transmitted to the main shaft 12, and the index pulse motor 13 rotates the main shaft 12 to give the work WK an arbitrary rotation angle during the crossover.

According to this embodiment, since the position of the work WK in the vertical direction is fixed, the treatment of the wire at the beginning and end of the winding, the crossover wire or the intermediate wire which shifts from the previous winding to the next winding. Processing of taps etc. becomes easy.

Further, even in the case of multiple connection, it is not necessary to vertically and vertically rotate each main shaft for supporting a work as in the conventional case, and a horizontal member having a plurality of nozzles attached thereto is vertically moved in parallel by a slider mechanism or the like. Alternatively, a simple structure such as swinging the nozzle itself in the vertical direction may be used. By simplifying the drive mechanism of the main shaft, inertia can be significantly reduced and the winding speed can be increased.

Furthermore, since the nozzle is driven separately in the axial direction and in the vertical direction, it is extremely easy to change the vertical stroke of the nozzle according to the change in the product thickness of the workpiece, and at the same time, the driving in the axial direction is performed. With a simple structure in which only one wing bar is moved in the front-back direction, it is possible to move three nozzles back and forth at the same time at the same stroke.

In the above embodiment, the case where two winding machines are used has been described, but it is also possible to use three winding machines or more. Even in this case, as in the conventional winding machine. A high-speed winding machine can be supplied at low cost without complicating the structure.

[0028]

As described above, in the outer rotor type winding machine according to the present invention, the nozzle is moved in the axial direction and the vertical direction and the work is rotated about the center line. Unlike the winding machine, the work does not move up and down, processing of the wire at the beginning and end of winding and the crossover wire is significantly facilitated, and the work drive mechanism is simplified.
The lighter weight enables higher speeds when multiple units are connected.

Further, in the above winding machine, the nozzle axial drive means and the vertical drive means are provided independently, so that the vertical stroke of the nozzle can be changed back and forth in accordance with the change in the product stack thickness. It can be performed independently of stroke changes, and can easily deal with various types of works.
