DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine required for producing a multi-layer coil such as a flyback transformer used for supplying an anode voltage of a cathode ray tube of a television receiver. It is about.

[0002]

2. Description of the Related Art A multilayer coil such as a flyback transformer used to supply an anode voltage of a cathode ray tube of a television receiver is disclosed in, for example, Japanese Patent Laid-Open No. 5-101.
As disclosed in Japanese Patent No. 959, the spindle supporting the bobbin is driven and rotated to alternately laminate the wire rod winding layer and the insulating film tape winding layer on the bobbin.

At this time, for example, as disclosed in Japanese Utility Model Publication No. 5-29124, by starting to wind the wire on the insulating film tape winding layer, the winding nozzle is controlled to move in multiple directions. , The wire rod is locked to the cut-and-raised part for locking the winding start end formed at one end in the width direction of the insulating film tape, then the winding is performed, and when the winding is finished, the winding nozzle is re-oriented in multiple directions. By controlling the movement of the insulating film tape to the other end in the width direction of the insulating film tape (the end opposite to the one end where the winding start end locking cut and raised portion is formed). A so-called wiring operation is performed in which the wire is locked to the raised portion.

[0004]

However, such wiring work has a difficulty in locking a wire material, which is a thin copper wire, to both of the small and easily deformed cut and raised portions. There is a case where the locking cannot be done by mistake (hereinafter, referred to as a wiring error), and the multilayer coil manufactured in such a state is a defective product, so it is necessary to select a good product.

However, after the manufactured multilayer coil is taken out from the supporting spindle group, even if an operator tries to select it, the wiring state in the lower layer is visually inspected because of the laminated structure. Therefore, visual inspection was obliged every time the wiring work was finished in the middle of manufacturing, but this could not improve productivity and it was easy to overlook wiring mistakes by visual inspection. The sex was not enough.

The present invention has focused on such a situation, and as a result of earnest studies to solve the problem, as a result of mounting a hook for locking a wire material having a wiring error, it is necessary to remove the multilayer coil from the spindle. They have found that the wire can be broken and defective products can be selected very easily.

[0007]

That is, in a winding machine according to the present invention, a spindle supporting a bobbin is rotated to alternately stack wire rod winding layers and insulating film tape winding layers on the bobbin. In the winding machine, when starting to wind the wire on the insulating film tape winding layer, a winding start end locking cut-out formed on one end in the width direction of the insulating film tape is controlled by moving a winding nozzle. When the wire rod cannot be locked erroneously with respect to the bent portion, the first hook for locking the wire rod and the insulating film tape by controlling the movement of the winding nozzle at the end of winding the wire rod Of the second hook that locks the wire rod when the wire rod cannot be erroneously locked to the winding end locking cut-and-raised portion formed at the other end in the width direction of the It is characterized in that mounted Pulling either one of the hooks. The first hook is preferably mounted on the spindle. More specifically, the jig receiving shaft mounted on the device frame so that it can be driven and rotated, and the engaging / separating part from the jig receiving shaft. It is preferable that the first hook is mounted on the bobbin supporting jig of the spindle configured with the bobbin supporting jig mounted so as to be able to move.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below. In FIG. 1, a longitudinal section of a spindle portion of a winding machine is shown. The spindle 1 is a device capable of being driven and rotated. It comprises a jig receiving shaft 3 mounted on the frame 2 and a bobbin supporting jig 4 mounted on the jig receiving shaft 3 so as to be engaged with and separated from the jig receiving shaft 3.

That is, the jig receiving shaft 3 is rotatably mounted on the casing 11 via the bearings 5, 6, the spacer 7, the compression coil spring 8, the inner ring 9 and the nut 10, and is attached to one end side thereof. A pair of steel balls 12
The steel ball 12 is pressed to the hole 15 side by a slider 14 which is mounted so as to be urged toward the other end side (the left side in the drawing) by the compression coil spring 13 and the steel ball 12 is pushed into the hole 15. 12 is projected a little.

The steel ball 12 is supported in the hole 15 so as not to protrude more than necessary and the casing 1
1 is attached to the device frame 2 by bolts 17, and a bearing retainer 18 is attached to the casing 11 by bolts 1.
The timing pulley 2 is mounted on the taper portion on the other end side (left side in the figure) of the jig receiving shaft 3
0 is mounted via a washer 21 and a bolt 22.

On the other hand, the bobbin supporting jig 4 is the jig receiving shaft 3
A rounded recess 23 is formed in a portion to be inserted into the hole 15 of FIG. Therefore, as shown in the drawing, by inserting the bobbin supporting jig 4 into the hole 15 of the jig receiving shaft 3 with the steel ball 12 protruding into the recess 23, the bobbin supporting jig 4 is fixed. Can be supported with respect to the jig receiving shaft 3,
Then, if necessary, the bobbin supporting jig 4 fitted in the hole 15 can be pulled to be separated from the jig receiving shaft 3.

At this time, when the slider 14 is moved to the left side in the drawing and brought into contact with the stopper 3a mounted on the jig receiving shaft 3, that is, when the pressing of the steel ball 12 is released, it is cured. The bobbin supporting jig 4 is inserted into the hole 15 of the tool receiving shaft 3 or is removed from the jig receiving shaft 3 to perform the support or separation.

Although not shown, the timing belt is stretched around the timing pulley 20 and the timing pulley 20 of the prime mover. Therefore, the jig receiving shaft 3 is driven in a predetermined direction by the operation of the prime mover. It can be rotated. Further, the stopper 24 is fixed to the intermediate portion of the bobbin supporting jig 4, so that the bobbin fitted in the bobbin supporting portion 25 can be positioned. Further, a flat portion 26 is formed in the intermediate portion, and a first hook 27 is fixed thereto, as shown in FIG. 2 which is a perspective view.

In FIG. 2, the bobbin 28 is fitted to the bobbin supporting portion 25 of the bobbin supporting jig 4 and is prevented from coming off by a locking means (not shown) mounted on the bobbin supporting portion 25. It is shown that the insulating film tape winding layer 29 is formed on the wire rod winding layer supported and formed on the bobbin 28.

In addition, in FIG. 3 which is a plan view and FIG. 4 which is a right side view of FIG. 3, after a predetermined winding is formed on the insulating film tape winding layer 29, the wire winding layer 30 is formed. ,
A thin copper wire is used for the winding end locking cut-and-raised portion 31 formed at one end in the width direction (longitudinal axis direction of the spindle) of the insulating film tape forming the insulating film tape winding layer 29. A state in which the locking of a certain wire rod 32 is about to be started is shown.

The wire rod 32 is guided by a winding nozzle 33 which is a hollow body and is mounted so as to be movable in multiple directions. A wire 32 from an unsupplied supply source is passed from the upper end opening toward the lower end opening, and the tip of the wire 32 passing through the lower end opening is fixed to a predetermined position of the device frame 2. It is wound around 34 and locked.

From this state, as will be described later, as shown in FIG. 2, the wire 32 is entangled with the terminal 28a on the left side of the bobbin 28, and the insulation forming the insulating film tape winding layer 29 subsequent thereto. The wire 32 for the winding start end locking cut-and-raised portion 35 formed at one end in the width direction of the film tape (the end opposite to the other end where the winding end locking cut-and-raised portion 31 is formed). Through the predetermined steps such as winding on the insulating film tape winding layer 29 to form a wire winding layer, and the state shown in FIGS. .

Next, in both figures, the winding nozzle 33
However, the movement is controlled in a predetermined manner so that the wire 32 is locked to the cut-and-raised portion 31 for locking the winding end. This allows
In a normal case (when no wiring error occurs, hereinafter, it is referred to as a normal case), wiring is performed as indicated by a broken line 32a. However, the cut and raised portion 31
When it is not possible to erroneously lock with respect to (when a wiring error occurs), wiring is performed as indicated by the solid line 32b.

Therefore, subsequently, as shown in FIG. 5 which is a plan view and FIG. 6 which is a right side view of FIG. 5,
When the winding nozzle 33 is pivotally moved at a predetermined angle around the second hook 36 fixed to a predetermined position of the device frame 2, in the normal case, the wire rod 3 is attached to the second hook 36.
No. 2 is not locked, but it is locked when a wiring error occurs. As described above, in the present invention, when the wire rod 32 cannot be erroneously locked to the cut-and-raised portion 31 for locking the winding end, the second hook 36 for locking the wire rod 32 is attached. ing.

The swiveling movement of the winding nozzle 33 is
In order to secure the locking of the wire member 32 that has been miswired by the second hook 36, while gradually lowering the wire member 32a indicated by the broken line in FIG. It is performed so as to turn. Therefore, in the case where a wiring error has occurred, as shown in FIG. 6, below the initial locking position (where the recess 36a is formed) shown in FIG. Is locked at the position.

Next, the winding nozzle 33 which has completed the turning movement is connected to the terminal 28b on the right side of the bobbin 28 as shown in FIG. 7 which is a plan view and FIG. 8 which is a right side view of FIG. After the wire rod 32 is moved to the place and the wire rod 32 is entangled with the terminal 28b, the wire rod 32 is wound and locked around the main hook 34 (see FIGS. 2 and 3). As a result, the wire 32 is locked to the terminal 28b and the main hook 34, but finally, the wire is cut by a cutter (not shown) at a predetermined position between the terminal 28b and the main hook 34.

By the above, the processing of the winding end is finished,
The process of the winding start end prior to this process is performed by the winding nozzle 3
3 is started by moving to the position of the terminal 28a on the left side in FIG. 2, that is, one end of the wire 32 is the main hook 3
4, the winding nozzle 33 is moved to the terminal 28a on the left side after the wire rod 32 is entangled with the terminal 28a, and then the terminal 28a and the main hook 34 are connected to each other. In, the wire 32 is cut by a cutter (not shown).

Subsequently, the winding nozzle 33 is controlled to be moved in a predetermined manner to form one end in the width direction of the insulating film tape constituting the insulating film tape winding layer 29 (a cut-and-raised portion 31 for winding end locking) is formed. The wire rod 32 is locked to the winding start end locking cut-and-raised portion 35 formed at the end opposite to the end of the wire 32.

FIG. 9 which is a plan view shows a state in which the wire rod 32 is completely locked to the winding start end locking cut-and-raised portion 35. Although not shown in the figure, when the wiring is normally performed, the wire 32
Is a cut-and-raised portion 3 for locking the start end located between the terminal 28a whose one end is entangled and locked and the winding nozzle 33.
It is locked at 5.

Subsequently, the winding nozzle 33 is moved to the terminal 28a. This state is shown in FIG. 10 which is a front view and FIG. 11 which is a right side view of this figure. Thus, when the wire rod 32 is normally locked to the winding start end locking cut-and-raised portion 35, the wire rod 32 is wired as shown by a broken line 32a in FIG. However, when such locking cannot be erroneously locked,
That is, when a wiring mistake is made, the winding nozzle 33 and the terminal 28a are wired as shown by the solid line 32b.

Then, the spindle 1 is driven and rotated in the direction indicated by the arrow in FIG. 11 by a predetermined angle. This state is shown in FIG. 12 which is a front view and FIG. 13 which is the right side surface of this figure. In addition,
The head 27a of the first hook 27, which is moved together with the rotation of the spindle 1, has a broken line 32a in FIG.
And a solid line 32b, and in FIG. 13, it is located on the right side of the broken line 32a.

Next, from this state, the winding nozzle 33
It is moved in the direction shown by the arrow in FIG. 12 and brought close to the surface of the insulating film tape wrapping layer 29. Accordingly, when the wire rod 32 cannot be locked erroneously with the winding start end locking cut-and-raised portion 35 (when a wiring error occurs), the wire rod 32 indicated by the solid line 32b is The head 27a of the first hook 27 is arranged so as to cross the place where the head 27a moves.

Subsequently, the spindle 1 is driven again, and is rotated by a predetermined angle in the direction shown by the arrow in FIG. 13 so that the first hook 27 is also moved therewith, and the original position shown in FIG. 9 is returned. Returned to. The head 27a of the first hook 27 is formed with a protrusion that can be hooked when returned to the original position shown in FIG. Therefore, if a wiring mistake occurs, the wire 32 can be locked by the first hook 27 and returned to the original position as shown in FIG. 14 which is a plan view.

However, in the normal case, even if the winding nozzle 33 is moved in the direction indicated by the arrow in FIG. 12 to approach the surface of the insulating film tape winding layer 29, the broken line 32b. The wire rod 32 shown by
Is not arranged so as to traverse where the head 27a of the first hook 27 moves, and is not locked by the head 27a of the first hook 27 that is returned to the original position.

As described above, according to the present invention, when the wire rod 32 cannot be erroneously locked to the winding start end locking cut-and-raised portion 35, the first wire rod 32 is locked.
The hook 27 is attached. In addition, in FIG.
Although the wire between the terminal 28a and the head 27a of the first hook 27 is not shown, the wire 32 has one end (not shown) entwined with the terminal 28a and locked.

Hereinafter, as shown in FIG. 15 which is a front view and FIG. 16 which is a right side view of this figure, the spindle 1 is driven and rotated in a direction indicated by an arrow in FIG. At the same time, the winding nozzle 33 is moved in the direction indicated by the arrow in FIG. 15 to perform a predetermined winding, and the wire rod winding layer 3 is formed on the insulating film tape winding layer 29.
0 can be formed, and then the winding nozzle 33
A predetermined movement control is performed so that the wire 32 is locked to the cut-and-raised portion 31 for locking the winding end (see FIG. 3). Thereafter, the winding end processing is performed through the same steps as described above.

If necessary, an insulating film tape winding layer 29 is formed thereon, and then a wire rod winding layer 30 is further formed thereon, and the wire rod winding layer 30 and the insulating film are formed as described above. The alternate stacking with the tape winding layer 29 is performed an appropriate number of times as necessary. At this time, if a wiring error occurs, the wire 32 is locked by the first and second hooks 27 and 36 one after another. Therefore, when the coil is removed from the spindle 1 that supports the manufactured multilayer coil, the plurality of locked wire rods 32 can be disconnected at once.

Since the wire rod 32 is as thin as about 0.04 mm, it is possible to break a plurality of wires all at once, and a so-called beard is generated due to the breakage, so that it is a defective product. It can be easily visually determined. Therefore, this effect is particularly remarkable when a large number of multilayer coils are manufactured at the same time by using a winding machine equipped with a large number of spindles 1 (multi-pin type winding machine). In addition, the wire material 32 having the wiring mistake is attached to the first and second hooks 2.
Since it can be locked with 7, 36, even during the manufacture of the multilayer coil, it is possible to easily visually determine that the product is defective.

Although one embodiment according to the present invention has been described above, in the present invention, only one of the first and second hooks 27 and 36 may be attached. It is most preferable to mount both the first and second hooks 27 and 36, but the present invention is not limited to this, and only one of the hooks can be mounted as necessary. Further, with respect to the first hook 27, by mounting the first hook 27 on the spindle 1, it is possible to perform movement control using the drive of the spindle 1. Therefore, it is preferable to mount the first hook 27 on the spindle 1, but separately from the spindle 1. You may wear it. However, in this case, it is necessary to install a mechanism or the like for controlling the predetermined movement of the first hook 27.

The spindle 1 may have any structure as long as it supports the bobbin 28 and can be driven and rotated in a predetermined manner. However, the jig receiving shaft 3 mounted so as to be driven and rotated can be used. And a bobbin supporting jig 4 attached to the shaft 3 so as to be engaged with and separated from the shaft 3, whereby a predetermined size can be obtained in accordance with the inner diameter of the bobbin 28 to be wound. Bobbin support jig 4 with outer diameter
It is preferable that the first hook 27 is attached to the supporting jig 4 in addition to the above, so that both can be exchanged at the same time.

The winding start end locking cut-and-raised portion 35 and the winding end locking cut-and-raised portion 31 may be of other forms, for example, cut on the side edge of the insulating film tape. A notch and a notched piece formed by cutting and raising (disclosed in Japanese Patent Application Laid-Open No. 58-63105), or one provided with a simple notch on the side end of an insulating film tape ( Actual Kaisho 5
7-130409), etc.,
Various forms can be appropriately selected and provided.

[0037]

As described above, according to the present invention, it is possible to easily visually determine a defective product in which a wiring error has occurred not only during the manufacturing of the multilayer coil but also after the manufacturing. Moreover, it is possible to obtain a winding machine capable of simultaneously exchanging both the bobbin supporting jig having a predetermined outer diameter and the first hook suitable for the bobbin corresponding to the size of the inner diameter of the bobbin to be wound.
