Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winding machine, and particularly to a flyer-type winding machine.

As is well known, there are two methods for winding a wire such as an enameled wire around a winding core such as a bobbin: a bobbin rotation method and a one-way flyer method, and the present invention is directed to the one-way flyer method.

FIG. 1 is a schematic diagram of an automatic winding machine with one type of flyer.

1 is a turntable, and turntable 1 is placed around its outer circumference.
Along the rotation direction R, the core supply device 2 and the wire winding device 3
, a wire end processing device 4, an unloading device 5, and the like are arranged.

A plurality of chucks 6 are attached to the circumferential surface of the turntable 1 at equal intervals along the circumferential direction.

The core supply device 2 mainly includes a feeder that sequentially feeds so-called cores such as a bobbin or a core instead of a bobbin, and a feeder that pushes the core toward the chuck 6 in synchronization with the intermittent rotational operation of the turntable 1. It is composed of an extrusion mechanism that causes a chuck 6 to grip the core.

Note that when manufacturing a single wire rod winding body such as bobbinless winding, the core supply device 2 is not necessary because the core is gripped in advance by the chuck 6 or directly held on the turntable 1. It is.

The wire winding device 3 is provided with a wire rod feeding tube 8 protruding from the wire rod winding device 3 and having a flyer 7 at its tip.

While rotating the wire rod feeding tube 8, the wire fed out from the hollow hole of the wire rod feeding tube 8 through the flyer 7 is wound around a winding core held by a chuck 6 and not rotating.

The wire rod feeding tube 8 moves away from or approaches the winding core depending on the winding state of the wire rod, thereby creating a wire rod winding body of a predetermined width on the winding core.

The detailed structure and mechanism of this part will be explained later.

In the wire rod end processing device 4, necessary end treatments such as adhesion, binding, soldering, and cutting of the wound wire rods are performed.

The unloading device 5 takes out the end-treated wire rod roll from the turntable 1 and transports it out of the machine using a chute or the like.

The operations of the core supply device 2, wire winding device 3, wire end processing device 4, and unloading device 5 described above are performed in synchronization with the intermittent rotational operation of the turntable 1, and the operations are performed from core supply to wire winding. The various steps up to the unloading of the rotating body are linked and performed automatically.

On the other hand, in recent years, with the aim of downsizing parts and reducing the amount of material used, so-called flangeless bobbins without seven langes have been used.
Alternatively, so-called bobbin-less winding, which is composed of a hollow winding without using a bobbin, is increasingly used.

FIG. 2 is a diagram showing the structure of a conventional winding machine for producing this bobbinless winding.

A plurality of support members 9 are fixed to the outer circumference of the turntable 1 at regular intervals along the circumferential direction, and a core 11 is integrally supported at the tip of the support member 9 via a first flange member 10. has been done.

Further, a second flange member 13 is detachably attached to the tip of the winding core 11 with a screw 12, and the first flange member 10 and the second flange member 13 face each other with the winding core 11 in between.

On the other hand, a hollow hole 14 is bored in the wire rod feeding tube 8, and a flyer 7 having a top guide 15 is attached to the tip of the wire rod feeding tube 8.

The flyer 7 rotates together with the wire rod feeding tube 8,
A wire 16 such as a self-bonding wire fed from the hollow hole 14 is passed through a guide roller 17 and then wound around a non-rotating core 11 from a top guide 15.

The wire rod feeding pipe body 8 has a winding core 11 depending on the winding state of the wire rod 16.
wire rod 1 due to its scanning.
6 is wound around the winding core 11 between the first flange 10 and the second flange 13 to form a wire rod wound body 18 having a predetermined width.

When the wire rod 16 is wound a predetermined number of turns, the winding core 11 is rotated together with the turntable 1 to the wire rod end treatment device 4, where the wire ends are treated, and then the screw 12 is turned to remove the wire from the second flange portion. 13 is removed from the core 11, and then the wire wound body 18 is taken out from the core 11.

After taking out the wire rod wound body 18@, the second flange member 13 was again fixed to the winding core 11 with the screws 12, and the wire rod 16 was wound in the same manner as described above.

When using a flangeless bobbin, the winding core 11 in FIG.
Attach.

Thereafter, in the same manner as described above, the wire rod 16 is wound around the flangeless bobbin by the guide of the first flange member 10 and the second flange member 13 to form the wire rod wound body 18.

When taking out the wound body 18 together with the bobbin, the second
After removing the flange member 13, the bobbin can be pulled out from the spindle.

However, with this conventional wire winding machine, as mentioned above, the wire rod]6
It is necessary to fix the second flange member 13 to the winding core 11 or the support shaft before winding the wire rod, and after winding, the second flange member 13 must be removed and then the wire rod wound body 18 must be pulled out.

Therefore, it takes time to attach and detach the second flange member 13,
The work efficiency is poor, especially in automatic winding machines that use a turntable or the like to automatically carry out a series of processes from feeding the winding core to unloading the wire wound body. 13, the number of steps for fixing and removing is increased, the machine becomes larger, and its operating rate decreases.

The purpose of the present invention is to eliminate such drawbacks of the conventional technology,
The object of the present invention is to provide a winding machine that can automatically and efficiently wind wires.

In order to achieve this objective distantly, the present invention provides a core supply device, a wire winding device, a wire end processing device, and a carry-out device in sequence along the rotation direction of the turntable,
The wire rod winding device includes a wire rod feeding tube body having a flyer, and while the wire rod feeding tube body is rotated, the wire rod is fed out from a hollow hole of the wire rod feeding tube body through the flyer and is wound around the non-rotating core. In addition, in the winding machine that creates a wire rod winding body of a predetermined width by moving the flyer relative to the winding core according to the winding state of the wire rod, the winding core is attached to the outer periphery of the turntable. A plurality of chucks are provided at predetermined intervals to hold the end of the wire rod and also serve as a first flange member, and a second flange member is attached to the tip of the wire rod feeding tube via a bearing, and the second flange A wire rod feeding pipe moving means for moving the member toward and away from the end of the core is provided, and when winding the wire, the second flange member is brought into contact with the end of the core to connect the chuck and the second flange member. The second flange member is separated from the winding core after the winding is completed, and the core having the wire rod winding body is carried out to the wire end processing device by rotation of the turntable. It is characterized by the presence of

Next, an embodiment of the present invention will be described with reference to the drawings.

3 to 5 are diagrams showing a first embodiment of the present invention.

As shown in FIG. 3, the chuck 6 attached to the outer circumference of the turntable 1 includes a receiving member 19 fixed to the turntable 1 and a rotating member 20 disposed thereon.
It is mainly composed of.

The rotating member 20 is rotatably supported on a shaft 21.
Both ends of the support member 1 are supported by the sides of the receiving member 190.

A spring 22 is inserted between the receiving member 19 of the shaft 21 near the turntable 1 and the rotating member 20, and the elasticity of the spring 22 causes the tip of the rotating member 20 to rotate toward the tip of the receiving member 19. It is dynamically energized.

The receiving member 19 and the rotating member 20 have flat end surfaces to form the first flange member 10.

For example, when one end of the winding core 11, which is made of a core whose surface is wrapped with insulating tape, is sandwiched between the receiving member 19 and the rotating member 20 as shown in FIG. 11 is firmly gripped.

This feeding of the core 11 to the chuck 6 and the gripping operation are performed by the aforementioned core supplying device 2, and the core 11 gripped by the chuck 6 is rotated intermittently by the turntable 1 for the next wire winding. It is transported to the device 3.

The wire winding device 3 is provided with a wire rod feeding tube 8 substantially coaxially with the winding core 11 .

A hollow hole 14 is formed in the center of the wire rod feeding tube 8 in the axial direction.
is bored, and its tip is open near the tip of the wire rod feeding tube 8.

A first tube 29 is slidably engaged with the outer periphery of the wire rod feeding tube 8 via a sliding bearing 28, a flyer 7 is connected to the tip of the first tube 29, and a flyer 7 is connected to the tip of the first tube 29. body 29
A second tube body 31 is attached to the outer periphery of the body via a rotation bearing 30.
are fitted.

This second tubular body 31 is supported by a casing 33 via a sliding bearing 32, and elongated holes 34 are formed at predetermined locations in the casing 33.

A sliding rod 35 is provided at a position facing the elongated hole 34 of the second tube body 31.
The sliding rod 35 passes through the elongated hole 34 and protrudes to the outside of the casing 33, and is connected to a sliding mechanism (not shown).

The wire rod feeding tube 8 is always elastically biased toward the winding core 11 by a spring 36.

A balance weight 23 is provided at a position symmetrical to the flyer 7 with the wire rod feeding tube body 8 at the center.

A small diameter portion 24 is provided at the tip of the wire rod feeding tube 8, and the second flange member 13 is fitted into this small diameter portion 24.

A bearing 25 that fits onto the small diameter portion 24 is provided inside the second flange member 13.
In order to maintain the stability of the flange member 13, two pieces are arranged in parallel.

The front surface of the second flange member 13 has a wire rod 16 to be wound thereon.
A flat surface 26 is formed to guide the wire rod winding body 18 and align the end faces of the wire rod winding body 18 in an orderly manner.
A concave portion 27 into which the tip of the first tip fits is provided.

Next, the winding operation of the wire 16 will be explained.

Before the winding core 11 comes to a position facing the wire rod feeding tube 8 due to the rotation of the turntable 1, the wire rod feeding tube 8 is moved to the rear side (Fig. 3) against the spring 36 by a traction means such as an air cylinder. (to the left when facing the page).

When the winding core 11 comes to a position facing the wire rod feeding tube 8, traction is stopped and the wire rod feeding tube 8 is moved toward the winding core 11 by the restoring force of the spring 36.

With this movement, the second flange member 13 comes into elastic contact with the end of the core 11, and the tip of the core 11 is fitted into the recess 27.

In this way, both ends of the winding core 11 are supported by the chuck 6 and the wire rod feeding tube 8.

Then, the wire rod feeding tube 8 rotates in the direction of arrow A at a predetermined speed.

Due to this rotation, the first tube 29 engaged with the wire rod feeding tube 8 and the flyer 7 connected to the first tube 29 rotate together, but the second tube 31 is rotated by the bearing 30. Does not rotate due to intervention.

The self-fusing wire 16 fed out from the hollow hole 14 of the wire feeding tube 8 is connected to the guide roller 17 and the top guide 1.

wrapped around.

As the wire rod 16 is wound, the sliding rod 3 is moved by the sliding mechanism.
5 move back and forth alternately along the direction of arrow B, and this sliding movement is transmitted to the flyer 7 via the second tube 31 and the first tube 29, so that the wire 16 moves between the first flange member 10 and the second It is wound in multiple stages between the flange member 13 and the flange member 13 .

Note that the sliding motion of the first tube 29 is not transmitted to the wire rod feeding tube 8 due to the interposition of the bearing 28.

Further, the rotation of the wire rod feeding tube 8 is not transmitted to the second flange member 13 due to the interposition of the bearing 25, and the second flange member 13 remains stationary due to contact with the winding core 11.

As described above, by repeatedly moving back and forth with the rotation of the fryer 7, the wire rod 16 is wound around the winding core 11 a predetermined number of turns to form the wire rod wound body 18.

Thereafter, the wire rod feeding tube 8 is pulled rearward again by the traction mechanism, the second flange member 13 is separated from the winding core 11, and the winding core 11 having the wire rod winding body 18 is moved to the next wire rod by the rotation of the turntable 1. Sent to terminal processing process.

After the end is processed, the rotating member 20 of the chuck 6
rotates against the elasticity of the spring 22, and the core 11 is taken out of the machine with the wire wound body 18 still attached.

6 and 7 show a second flange member 13 according to a second embodiment, in which the end of the winding core 11 abuts the flat surface 26 of the second flange member 13. The flat surface 26 is not provided with the four parts 27 as in the first embodiment.

Further, the structure of the second flange member 13 may be a chuck type so that the end of the winding core 11 can be gripped.

In the present invention, it is convenient for the second flange member 13 to be attachable to and detachable from the wire rod feeding pipe body 8 in order to perform various types of winding.

In addition, since the second flange member 13 may swing slightly when the wire rod 16 begins to be wound, a ring body with uneven thickness is fitted onto the second flange member 13 to lower the center of gravity as a whole. It is good to prevent shake.

The present invention has the above-mentioned configuration, and since the flange member is attached to the tip of the wire rod feeding tube body, there is no need to attach and detach the flange member each time the wire is wound, as in the conventional case, and automatic operation is possible. Winding can be carried out easily and efficiently.

In addition, the flange member is attached to the wire rod feeding tube via a bearing, and during winding, it comes into contact with the non-rotating winding core and remains stationary, so there is no worry of the wire rod being damaged by the flange member. has advantages.

Furthermore, by changing the position where the winding core is held by the chuck, the distance between the chuck and the second flange member, that is, the winding width of the wire rod winding body, can be easily adjusted, and the chuck can also hold the first flange member. Since it also serves as a part, the number of parts can be reduced.
