Abstract

PURPOSE:To provide a winding equipment which is able to stably produce an air-core coil of not only single winding but also multiplex winding such as duplex or triplex winding. CONSTITUTION:A winding section is composed of a winding frame 1 and a wall 3 whose surfaces in contact with wires are made spiral and 2 winding shaft 2 wound with wires, where the winding shaft 2 is fixed to the winding frame 1. The winding frame 1 is driven by a motor 5 through the intermediary of a spline shaft 22 and a pulley 4. The winding frame 1 is made to move back and forth in the axial direction of the spline shaft 22 by a motor 7 through the intermediary of a rack 20 and a pinion 21. Furthermore, a nozzle mechanism 13 which feeds wires 12 to a winding section putting then in order and a spool table 27 which set the wires 12 are provided. By this setup, when a wire is wound as pinched between a winding frame and a wall, a gap is not induced between the winding frame and the wall, so that wires are prevented from getting out of position, and in result multiplex winding can be stably carried out. A proportional control is not required depending on spiral pitches, so that a winding equipment of this design can be made simple in structure.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine capable of multiple winding.

[0002]

2. Description of the Related Art A conventional winding machine is a single winding machine, in which a wire rod is hooked by a rotating winding frame with a claw and wound around a winding shaft, and one wire per rotation is synchronized with the rotation of the winding frame. The wire was supplied from a nozzle that moved in the coil growth direction at a speed corresponding to the diameter.

[0003]

In carrying out the multi-layer winding this time, first, a flat wall which is paired with the winding frame and sandwiches the wire is provided. However, due to the resistance of the wire rod to be caught in the gap generated at the first winding, the wall was pushed open to sneak in and collapsed, so that the wire could not be rolled. This can be improved to some extent by providing a mechanism for precisely adjusting the gap between the winding frame and the wall, but as the wire diameter increases, the winding resistance further increases and collapses.

An object of the present invention is to obtain a winding device capable of stably producing not only single winding but also multiple winding coils such as double winding and triple winding.

[0005]

In order to achieve the above object, in the winding machine of the present invention, the surfaces of the winding frame and the wall which are in contact with the wire are formed in a spiral shape having a pitch substantially equal to the diameter of the wire. is there.

The spiral part of the winding frame and the wall has some drawbacks for the reason described below even if the step is similar to the spiral, but
The above object can be achieved.

[0007]

In the winding machine constructed as shown in FIGS. 1 and 2, as shown in FIGS. 5 and 6 between the lowest portion of the spiral surface of the winding frame and the lowest portion of the spiral surface of the wall. 90 degrees (Fig. 7), 180 degrees (Fig. 8), while sandwiching the wire rod and moving the winding frame at a speed of one wire diameter per winding in the direction in which the coil extends.
When rotated at 270 degrees (FIG. 9) or 360 degrees (FIG. 10), the first winding can be performed without forming a gap between the wire and the wall. Therefore, the coil will not collapse (the figure shows an example of double winding). Also, if the pitch of the spiral is close to the wire diameter, the coil of close contact winding can be manufactured only by rotating the winding frame while applying a constant pressure to the winding frame in the direction of pushing the wire rod.

[0008]

EXAMPLE An example of a two-layer winding will be described with reference to FIGS. 1. Pull the wire from the spool (11) to the pulley (19)
(23) (9), reverse-travel prevention device (14), nozzle (8)
Through in order, and bring it out to the position of the fixed blade (16). 2. The motor (10) is rotated to advance the nozzle (8) to the position where the winding frame (1) and the wall (3) sandwich the wire rod and push out the wire rod. At this time, since the reverse movement preventing device (14) is working, the wire does not retract. 3. With the claw of the winding frame on top, turn the motor (7) to C
Rotate to the CW side to advance the winding frame and sandwich the wire.
(States in FIGS. 5 and 6) 4. When the winding frame is rotated by the motor (5) via the timing belt (6), the sandwiched wire is hooked by the claws and drawn in the rotating direction of the winding frame, and the winding shaft (2)
Wrapped around. 5. The motor (7) retracts the winding frame at a speed corresponding to one wire diameter per winding. (CW direction) 6. When the predetermined number of windings is completed by the operations of 4, 5, the motor (7) is rotated in the CW direction to pull the winding frame to the rear end, and the winding shaft is pulled out from the coil. 7. When the movable blade (15) is moved to cut the wire between the movable blade (15) and the fixed blade (16), the coil falls on the shooter (17) and enters the storage box (18). 8. From the second piece, the operations of 2 to 7 are repeated for continuous production.

This time, a winding machine was manufactured by using a stepping motor as the motor (7), and the winding frame (1) was manufactured according to the wire diameter.
By changing the retreat speed per winding, using a winding frame and wall with a spiral pitch of 1.8 mm, 1.8 mm, 2.0
It was possible to stably manufacture a double-coiled coil of good adhesion winding by winding a wire having three different diameters of mm and 2.2 mm.

In the above example, the motor (7) performs the proportional control of retracting the winding frame at a speed of one wire diameter per winding, but when the pitch of the spiral is close to the diameter of the wire. The winding can be performed by simply rotating the winding frame while applying a constant force in the direction of pressing the winding frame against the wall.
In this case, a torque motor is used as the motor (7). When the coil is pressed (CCW direction), resistance is added to increase or decrease the torque, and when the winding shaft is pulled out (CW direction), the motor is directly connected to move at 100% output. Good.

In the above example, when the pitch of the spiral is close to the wire diameter, a mechanism (cylinder or the like) dedicated to pulling out the winding shaft.
If the above is prepared, a constant pressure may be applied by a spring.

In the above example, the spool (11) and the pulleys (9) (23) have three stages, and the pulley (19) has two stages.
Triple winding is possible by changing the nozzle to one for three.

In FIG. 1 and FIG. 2, a single winding coil can be manufactured by using only one wire passing through the nozzle.

In the above example, even when the surface of the winding frame and the wall that is in contact with the wire is made to have a step similar to a spiral surface, multiple winding can be performed by retracting the winding frame at a speed corresponding to one wire diameter per winding. However, there is a risk that the wire coating may be damaged by the step.

[0015]

Since the present invention is constructed as described above, it has the following effects.

By winding a wire rod between a winding frame having a spiral surface having a pitch close to the wire diameter and a wall, it is possible to stably perform not only single winding but also double winding, triple winding and the like.

If a winding frame and a wall having a spiral pitch close to the wire diameter are used, a winding wire can be formed by simply rotating the winding frame by applying a constant pressure between the winding frame and the wall so that the coil does not collapse. The proportional control for retracting the winding frame at the speed of one wire diameter per winding becomes unnecessary. Further, in the case of this configuration, compared to the conventional single winding machine, the proportional control of moving the nozzle in the coil extending direction at a speed corresponding to one wire diameter per winding is not required. Can be simplified.

By winding the coil by sandwiching it between the spiral surface and the spiral surface, the coil is always pressed by the surface, and a coil of good close winding can be manufactured.
