Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for manufacturing a coil by winding a wire around a coil bobbin, and more specifically, a wire required for cutting the wire or tying the wire around terminals provided on the bobbin. And a structure of a winding machine for performing the treatment of the wire bending portion formed in the bobbin body at the start and end of winding.

[0002]

2. Description of the Related Art In a coil winding machine that winds a wire around a bobbin that rotates while supplying the wire under a predetermined tension from a nozzle, the wire is entwined around terminals provided on the bobbin before and after the winding. . The wire entangled with the terminal is cut with a cutter, etc., but the tension is always applied to the wire, so the wire is held between the nozzle and the cutting part during cutting so that the wire does not come off from the nozzle due to cutting. There is a need to.

Therefore, in these winding machines, for example, a discarding pin for temporarily winding the wire rod is provided. With this, for example, before the start of winding, the wire is first entangled with the discarding entanglement pin, and in this state the nozzle moves around the terminal to entangle the wire rod with the terminal, Cut the wire leading to the terminal near the terminal.

At the end of winding, the wire rod guided from the winding portion of the bobbin to the terminal is entangled with the terminal by moving the nozzle, and further entangled with the discarding entanglement pin, and then the wire rod extending from the terminal to the discarding entanglement pin. Cut near the terminals.

[0005] The discarding entanglement pin is a pin having a notch formed at the tip for entanglement of the wire rod, and the outer periphery of the discarding entanglement pin removes the scraps of the wire rod entangled after the wire rod is cut. A sleeve is attached to do this. This sleeve is moved along the discarding entanglement pin by the driving means and removes the wire rod entangled at the tip. Further, in order to reduce the waste of the wire rod, it is desirable that the throw-out binding pin be located near the bobbin, but if it is too close, it may interfere with other work. For this reason, for example, the throwing entanglement pin is provided with a moving means so as to be retracted to a distant position when not in use.

By the way, the wire wound around the terminals before the start of winding is guided toward the center of the bobbin, bent at a right angle, and then wound around the body of the bobbin. In addition, the wire material that has been wound is bent at a right angle again and then guided to the terminal. Therefore, the wire bending portion is formed at the beginning and the end of the winding on the body of the bobbin, but this bending portion is not formed only by the movement of the nozzle, and the nozzle is moved while pressing the wire on the body. It is formed by doing. For this purpose, a wire holder is used, and the formed bent portion is fixed to the body of the bobbin with an adhesive tape, for example. The wire retainer is driven by the driving means to push the adhesive tape to the bobbin body,
Displaces to and from the retracted position. Furthermore, a moving means for retracting to a position apart from the bobbin together with the driving means is provided so as not to interfere with the winding work.

[0007]

This winding machine has a problem in that the structure is complicated and the manufacturing cost is high because many actuators are used as various driving means and moving means.

The present invention has been made to solve the above problems, and it is possible to rationalize the structure of a coil winding machine by sharing a moving means and a driving means of working members which do not need to operate at the same time. To aim.

According to a first aspect of the present invention, a bobbin provided with a body around which a wire is wound and a terminal for entwining the wire is mounted, a rotary spindle, and a nozzle for supplying the wire to the bobbin. Along with the means for moving the nozzle, the discarding tie pin that temporarily locks the wire to cut the tie entangled to the terminal, and the discard entanglement pin to remove the wire from the discard entanglement pin. A coil winding machine comprising: a wire-displacement member that is displaced and a wire retainer that is displaced between an advanced position and a retracted position to temporarily press the wire rod against the body portion. And a means for integrally driving and.

According to a second aspect of the present invention, in the first aspect of the present invention, two arms A and B, which respectively move in three axial directions with respect to the spindle, are provided, and one arm A supports the nozzle. Then, the arm A constitutes the nozzle moving means, and the other arm B supports the waste binding pin and the wire retainer.

According to a third aspect of the present invention, in the first aspect of the present invention, a tubular member is provided with a notch at the tip of the throw-in pin, and a rotary member accommodated inside the tubular member so as to be freely rotationally displaced. And a means for rotationally displacing the rotating member so as to sandwich the wire rod between the rotating member and the notch.

[0012]

According to the first aspect of the present invention, the wire discharging member for the throwing entanglement pin and the driving means for the wire retainer are common, and the structure of the winding machine is simplified. Since it is not necessary to perform the wire discharging operation and the wire pressing operation at the same time, the work efficiency is not deteriorated even if the driving means is shared.

According to the second aspect of the present invention, since the discarding entanglement pin and the wire retainer are supported by the arm B that moves in the three axial directions, the discarding entanglement pin and the line retainer are attached to the bobbin and the nozzle. It is possible to move arbitrarily. Therefore, the throwing-out entanglement pin and the wire pressing tool do not interfere with other operations, and the throwing-out entanglement operation and the wire pressing operation are not performed at the same time, so that an efficient work can be performed.

According to the third aspect of the present invention, since the wire member is sandwiched between the rotating member and the notch, it is not necessary to move the nozzle to entangle the wire member with the discard entanglement pin. The time required is reduced.

The winding machine shown in FIG. 1 has a bobbin 3 having a body portion 3A for winding a wire and two terminals 3B for entwining the wire.
Is equipped with a spindle 4 that rotates and a nozzle 13 that supplies a wire material for winding under a constant tension. The nozzle 13 is supported by a moving mechanism (not shown) and moves in three axial directions as needed. Further, it freely rotates between a vertical position and a horizontal position on a vertical plane parallel to the axis of the spindle 4.

A discarding entanglement pin 19 and a wire retainer 18 are provided for processing the start and end of winding the wire on the bobbin 3. These are attached to a slider 32 which is supported by a stand 30 provided at a fixed position via a guide 31. The slider 32 is displaced in parallel with the axis of the spindle 4 by the guide of the guide 31 according to the expansion and contraction of the cylinder 33.

The discarding binding pin 19 is erected upward at the tip of the slider 32. A notch 34 is formed at the tip of the throw-away binding pin 19 for binding the wire rod by the movement of the nozzle 13. A wire discharging sleeve 35 as a wire discharging member is slidably fitted in the outer periphery of the throw-away binding pin 19 in the axial direction.
This discharge wire sleeve 35 is lifted to remove the wire material entangled at the tip of the waste entanglement pin 19. A groove 36 is formed on the outer circumference of the discharge sleeve 35, and a plate-shaped holder 37A having a bifurcated tip is fitted into the groove 36.

The holder 37A passes through the slider 32.
It is connected to a similarly plate-shaped holder 37C arranged below the slider 32 via a book rod 37B. The wire holder 18 bent in a crank shape is fixed to the tip of the holder 37C. A spring 38 is interposed between each of the holders 37A and 37C and the rod 37B between the rod 37B and the slider 32, which form the connecting member 37, and the connecting member 37 is biased downward.
Further, a rod 40 extending from an air cylinder 39 as a driving means attached to the slider 32 is coupled to the holder 37C.

Next, the operation will be described.

At the start of winding the bobbin 3, the nozzle 13
The end of the wire sent out from is entwined with the discard entanglement pin 19. In this state, the nozzle 13 goes around the one terminal 3B to entangle the wire with the terminal 3B. After being entwined, the wire rod extending from the entanglement pin 19 to the terminal 3B is cut near the terminal 3B by a cutter (not shown).

The wire rod remaining entangled in the discarded entanglement pin 19 is removed by the discharge wire sleeve 35. That is, when the rod 40 is contracted by driving the air cylinder 39, as shown in FIG.
As shown in FIG. 7, the coupling member 37 displaces upward while compressing the spring 38 and fits in the groove 36.
The wire discharge sleeve 35 is pushed up via the. As a result, the discharge wire sleeve 35 slides in the direction of the tip of the waste entanglement pin 19, and the wire material remaining entangled at the tip of the pin is pushed out and removed.

The nozzle 13 wraps the wire around the terminal 3B,
The bobbin 3 moves in the direction of the body portion 3A. This makes terminal 3
The wire rod is guided from B in the axial direction. Next, by driving the cylinder 33, the slider 32 is moved to move the wire pressing member 18 above the body portion 3A. Then, the air cylinder 39 is released, and the coupling member 37 is pushed down by the bias of the spring 38. As a result, the wire retainer 18 descends and the body 3A
Press the wire onto the.

In this state, the nozzle 13 is tilted in the horizontal direction to make one round around the body 3A, so that the wire rod 1
It is bent at about 90 degrees at the position of 8, and the bent portion is locked to the body 3A by the wire rod wound around the body 3A. In this state, the air cylinder 39 is driven to pull up the wire retainer 18, and the cylinder 33 is driven to retract the slider 32 to a position that does not interfere with the front or rear of the bobbin 3.

Next, the nozzle 13 is returned to the vertical position again, and the spindle 4 is rotated to wind the wire rod fed from the nozzle 13 to the body portion 3A. The nozzle 13 moves in the axial direction during winding so that the wire is evenly wound around the body portion 3A.

When the winding is completed, the slider 32 is moved again to move the wire pressing member 18 above the winding ending portion, the air cylinder 39 is released, and the wire pressing member 18 moves the winding ending portion to the body portion. Hold down to 3A. In this state, the nozzle 13 is moved in the direction of the terminal 3B, so that the wire rod is attached to the wire holder 1.
It will be refracted at about 90 degrees at position 8. An adhesive tape is attached to the bending portion by a taping unit (not shown), and the bending portion formed at the end of the winding is fixed to the body portion 3A by this tape.

The nozzle 13 moved near the terminal 3B is
Just like before winding, wrap around the terminal 3B and wire the terminal 3
Engage with B. After that, the wire rod is moved to the throw-away binding pin 19 and the wire is bound in the notch 34 at the tip of the throw-away binding pin 19.

In this state, the cutter not shown is the terminal 3B.
The wire rod from the end to the throw-in pin 19 is cut in the vicinity of the terminal 3B.

In this way, the winding machine uses the wire pressing member 18 at the beginning and end of winding of the wire to form the wire bending portion and to hold the wire end necessary for entanglement with the terminal. This is performed by using the throw-away binding pin 19. Since the wire retainer 18 and the wire discharge sleeve 35 of the throw-away pin are driven by the same air cylinder 39, the configuration is simplified as compared with the case where individual drive means are provided, and the manufacturing cost of the winding machine is reduced. be able to. Since it is not necessary to use the wire retainer 18 and the discharge sleeve 35 at the same time due to the nature of the work, there is no risk of the work efficiency being lowered even if they are integrally driven by the same air cylinder 39.
