Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a winding device for an electric coil having a core, such as a vertical coil installed in the deflection yoke of a television receiver. be.

(Prior Art) The above-mentioned vertical coil is constructed by forming a cylinder by abutting two ferrite cores 1 having an arcuate cross section as shown in FIG. 5, and winding both cores 1.

Conventionally, as shown in FIGS. 1 and 6, this type of coil winding device includes a holder 2 that removably holds a ferrite core 1, and a winding device that winds the core 1 held by the holder 2. Winding arm 6
An automatic wire winding device is used.

The holder 2 has holding arms 8, 80 that can move forward and backward in conjunction with a reciprocating device such as an air cylinder.
and holding receiving pieces 81 and 82 protruding from the holder 2.
The clamping mechanism is equipped with a clamping mechanism consisting of:
Both ends (11 and 12 in FIG. 5) of one side of the core 1 are detachably held.

Further, a locking pin 5 is fixed to the holder 2 for locking the conducting wire 7 during winding operation as described later.

The winding arm 6 is connected to the core 1 as shown in FIG.
The operation of letting out the conducting wire 7 while moving relatively spirally around the core 1 from one end to the other end is repeated a predetermined number of times, and a plurality of (for example, three to three) wires are drawn out around the core 1.
9) forms the winding layer.

Furthermore, the coil winding device is provided with a wire presser 90 (see FIG. 4) connected to the reciprocating device and used to change the winding direction of the conductor 7 during the winding operation as described later. It is thus possible to temporarily bring the distal end into contact with the core 1 held in place.

The conducting wire 7 is fed out with a predetermined tension from a conducting wire supply device (70 in FIG. 1), and the leading end of the conducting wire passes through the tip of the winding arm 6 and is fixed to the holder 2 20.

The winding operation is performed as follows by moving the winding arm 6 relative to the holder 2.

For example, as shown in FIG.
After going around the core 1, the conductor 7 is hooked onto the locking pin 5 and transferred to the other end of the core 1.

At the other end, the wire presser 90 is disposed with its tip end in contact with the core 1, and the conductive wire 7 is temporarily held down by the wire presser 90 so that the wire 7 is not wound in the winding direction with respect to the core 1. change direction.

The winding arm 6 uses the other end as a winding start point and rotates around the core 1 toward the holder 2 in a spiral manner to form a first winding layer.

Next, the conducting wire 7 is again hooked onto the locking pin 5 and returned to the winding start portion of the core 1, and the second winding layer is formed by the rotational movement of the winding arm 6 in the same manner as described above.

Thereafter, similar operations are repeated a necessary number of times to form, for example, 4 to 9 winding layers.

After a predetermined number of winding layers have been formed, the holding arms 8, 80 are moved forward and the core 1 is removed, thereby completing the vertical coil.

(Problem to be Solved) In the coil winding device described above, when removing the core 1 after winding from the holder 2, the bundle of conductive wires 7 hung on the locking pin 5 (as indicated by the arrow in FIG. B)
It is necessary to remove it from the locking pin 5.

However, the locking pin 5 is normally curved with a large curvature as shown in the figure in order to prevent the conductor 7 from detaching, and since a considerable amount of tension is acting on the conductor, Therefore, the core 1 is the holding piece 8
1 and 82. Therefore, it was not easy to remove the core 1 from the holding arms 8, 80 and the holding receiving pieces 81, 82 and at the same time to remove the bundle of conductive wires 7 hung from the locking pin 5 from the locking pin 5. Moreover, at this time, it is inevitable that a larger tension is applied to the bundle of conductive wires 7 by the locking pin 5, and as a result, the coating of the conductor wires 7 may be peeled off by the locking pin 5. In some cases, the laminated portion of the winding wire (arrow A in FIG. 6) collapsed.

(Means for Solving the Problems) A coil winding device according to the present invention includes a holder 2 that removably holds a core 1, and a winding wire that winds the core 1 held by the holder 2. It is equipped with an arm 6 and a reciprocating device such as an air cylinder device having an output section that can approach and separate from the core 1 held in the holder 2.

The output part of the reciprocating device is provided with a protruding locking pin 5 for locking a return wire 71 returning from the winding end of the first winding layer to the winding start of the second winding layer. are doing.

The locking pin 5 is driven by a reciprocating device,
It is possible to reciprocate between a retracted position where the return line 71 is to be locked and an advanced position closer to the outer peripheral surface of the core 1 than the retracted position.

The reciprocating device holds the locking pin 5 at the retracted position during the winding operation, and drives the locking pin 5 to the forward position after winding is completed.

(Operations and Effects) During the winding operation, the locking pin 5 is set at a retracted position away from the core 1, and in this state, winding is performed in the same manner as in the prior art.

When the winding is completed, the reciprocating device is operated to move the locking pin 5 to an advanced position approaching the outer peripheral surface of the core 1.

As a result, the tension acting on the bundle of conductive wires 7 hung on the locking pin 5 is released, and as a result, the core 1 can be easily removed from the holder 2.

Therefore, the winding is not damaged by the locking pin 5.

(Embodiment) FIG. 1 shows an example in which a coil winding device according to the present invention is applied to a winding process of a vertical coil installed in a deflection yoke of a television receiver.

The holding arms 8, 80 are respectively connected to the output parts of a pair of main air cylinder devices 30, 31 attached to the holder body, and can advance and retreat by driving the main air cylinder devices.

Further, a movable piece 50 is disposed between both the holding and receiving pieces 81 and 82 so as to be movable back and forth, and the movable piece 50
A locking pin 5 is fixed to.

The movable piece 50 is connected to the output part of the auxiliary air cylinder device 3 attached to the holder body, and can advance and retreat in the movement direction of the holding arms 8 and 80 by driving the auxiliary air cylinder device.

Incidentally, each output section of the main air cylinder devices 30, 31 and the sub air cylinder device 3 is connected to the support column 21.
By operating a switch 32 installed in the vehicle, the vehicle can simultaneously move forward and backward.

The conductor 7 is attached to the support 21 by a locking pin 5 as described later.
The locking guide 9 used when hanging the air motor 3
It is equipped in conjunction with 3.

On the other hand, the winding arm 6 is rotationally driven by a winding motor 40, and is started and stopped by controlling the motor.

The operation of the coil winding device will be described below.

First, with the main air cylinder devices 30, 31 and the sub air cylinder device 3 advancing the holding arms 8, 80 and the movable piece 50 toward the rotation center of the disk 22, the holding arms 8, 80 and the holding receiving piece 81 , 82, the switch 32 is operated to move the holding arms 8, 80 and the movable piece 50 backward. Thereby, the core 1 is held in the holder 2 as shown in FIG.

Further, when the conducting wire 7 is to be returned to the winding starting portion of the winding layer after being hooked to the locking pin 5, the winding motor 40 is stopped and the main motor 4 is rotated clockwise.

When locking the conductor 7 to the locking pin 5, the air motor 33 operates, and the locking guide 9 is reversed in the direction of the arrow as shown in FIG. The conductive wire 7 is pressed down toward the core 1, thereby guiding the conductive wire 7 to the locking pin 5.

When winding is completed, the switch 32 is operated to move the holding arms 8, 80 and the movable piece 50 forward. As a result, the holding of the core 1 by the holding arms 8, 80 and the holding pieces 81, 82 is released, and the locking pin 5 advances toward the core 1, and the conductor 7 hooked on the locking pin 5 is released.
