(3) When it is said that the winding shaft 28 is rotated, it means that the winding shaft 28 is rotated by rotating the stepping motor 35.

The configuration and functions of the winding device according to the embodiment of the present invention have been described above, and the main components are provided as follows.

That is, a plurality of winding shafts 28 driven by a stepping motor 35, which is a first motor whose rotation stop position shown in FIG. 6 can be arbitrarily controlled, are mounted on a drum-type rotary table 19 shown in FIG. It is provided so as to protrude in the radial direction with respect to the rotation axis of the rotary table 19.

It is configured to rotate synchronously with the

Cutters 95 and 96 are provided close to the winding shaft 28 for cutting the wire 22 and holding it after cutting.

The actual operation will be explained below.

In FIG. 5, the wire 22 is guided by rollers 24 and 25 and introduced into the guide nozzle 54.

Rotary table 19 completes index rotation. As shown in FIG. 13, the wire 22 is held at the tip of the guide nozzle 54 by cutters 95 and 96. The lever 42 is disengaged from the stopper 40 by a power not shown in FIG. 7, and at the same time as shown in FIG. is transmitted to the shaft 28. The air cylinder 66 maintains the pushing state and therefore the guide nozzle 5
4 is in a position parallel to the radial terminal 6 as shown by π in FIG. Both the air cylinder 62 and the air cylinder 63 are maintained in a pushed state, and therefore the guide nozzle 54 is at the position μ in FIG. 27 and is perpendicular to the winding shaft 28. The guide nozzle 54 is moved and moved up and down, and the winding shaft 28 is rotated and positioned with respect to the terminal to be wound. This position is the same as the starting position of the winding A motion, winding B motion, winding C motion, and winding D motion described below. For example, in the case of a coil bobbin 9 having a radial terminal 6, it is J or k in FIG. The above preparation operations are common to all examples. [Example A] A case of winding a wire around a coil bobbin 9 having a radial terminal 6 shown in FIG. 1 will be described.

Rotate the winding shaft 28 to position the guide nozzle 54 at the positions 10)J in FIG. 14 and k in FIG. 14.

The following operations are continuously performed as shown in FIG. 14 while the stepping motor 75 is arbitrarily rotated in forward and reverse directions with respect to the radial terminal 6 to appropriately move the guide nozzle 54 up and down. By rotating the first winding shaft 28, the radial terminal 6 moves in any direction relative to the guide nozzle 54 (winding shaft rotation amount b)
.

2. The guide nozzle 54 is moved in the axial direction of the coil bobbin 9.

(Guide nozzle movement amount a). The third winding shaft 28 is rotated by the same angle in the opposite direction to the first direction.

4. The guide nozzle 54 is moved by the same amount in the opposite direction to 2.

By repeating the above operation an arbitrary number of times, the guide nozzle 54 winds the wire 22 around the radial terminal 6 while drawing the locus shown in FIG. 14, assuming that the radial terminal 6 is stationary. This is called the winding A motion. As shown in FIG. 21 (showing the case of a radial terminal), a wire rod 22 whose one end is held by the cutters 95 and 96 and the other end is wound around the radial terminal 6 or the axial terminal 6 is held by the cutter 1 (not shown). , cut near the radial terminal 6 or axial terminal 6 (position 1 in FIG. 21).

The air piston 99 is set to 0n, the cutters 95 and 96 are opened, and the wire rod 22 that is being held is released. The released wire rod 22 is collected into a box (not shown). (This is called a katsuta movement). As shown in FIG. 22, the wiring groove 7 is selected by rotating the winding shaft 28 (winding shaft rotation amount m), and the guide nozzle 5
4 to wiring groove 7 (guide nozzle movement amount n)
, lower the guide nozzle 54 (guide nozzle lowering amount 0)
) The wire 22 is wired into the wiring groove 7 (hereinafter referred to as a tapping operation). Next, as shown in FIG. 23, the winding shaft 28 is rotated to select the crossing groove 8 (winding shaft rotation amount P). Move the guide nozzle 54 to the crossing groove 8 where the wire is to be wound (guide nozzle movement amount Q) and lower it by an arbitrary amount (guide nozzle lowering amount R)
. By rotating the winding shaft 28 by about 1/2 rotation (winding shaft rotation amount S), the wire 22 is wired into the transition groove 8 . This is called wiring operation. FIG. 15 shows the trajectory of the guide nozzle 54 when the coil bobbin 9 is stationary. As shown in FIG. 24, by raising the guide nozzle 54 (guide nozzle rise amount T) and rotating the winding shaft 28 by a predetermined number of turns (winding shaft rotation U), the wire 22 is connected to the coil bobbin having the radial terminal 6. 9 and stop the winding shaft 28 at the next setting position (W in Fig. 24) (hereinafter referred to as winding operation).
. υ in FIG. 24 is the position of the guide nozzle 54 before the winding starts. During winding, the stepping motor 35 of the winding shaft 28
Traverse can also be performed by electrically synchronizing the rotation of the stepping motor 52 that moves the guide nozzle 54 with the rotation of the guide nozzle (guide nozzle movement amount
). Repeat the wiring and winding operations as described above as appropriate.

As shown in FIG. 25, the winding shaft 28 is rotated to select the wiring groove 7 (winding shaft rotation amount Y), and the guide nozzle 54 is moved to the position of the radial terminal 6 to be wound (guide nozzle movement amount Z). ).

By lowering the guide nozzle 54 (guide nozzle lowering amount α
) By rotating the winding shaft 28 (winding shaft rotation amount β), the wire rod 22 is wired into the wiring groove. The guide nozzle 54 is raised (guide nozzle raising amount γ) and positioned relative to the radial terminal 6. Hereinafter, this is referred to as the tapping operation. Next, winding operation A is performed.

As shown in FIG. 11, raise the guide nozzle 54 (
Guide nozzle rise amount δ).

Due to the ON of the air cylinder 102, the cutters 95 and 96 enter between the terminal 6 and the guide nozzle 54, and the air piston 99
0ff and the spring force of the tension spring 100 cause the cutter to be 95.
, 96 cut the wire 22 between the terminal 6 and the guide nozzle 54 and hold it at the same time. Air cylinder 102 to 0
ff and move the cutters 95 and 96 back. This state is shown in FIG. The guide nozzle 54 is lowered. Hereinafter, it will be referred to as Katsuta-1 movement. By repeating the above-mentioned winding A action, cutter one action, tap in action, wiring action, winding action, tab out action, and cutter one action, winding including winding many times around many terminals is performed. is possible.

After all of the above operations are completed, the guide nozzle 54 is moved to a fixed position where it does not interfere with the coil bobbin or the like during index rotation of the rotary table 19, as shown in FIG. The guide nozzle 54 is moved up and down to return to the normal position. The winding shaft 28 is rotated to return the winding shaft 28 to its home position. A power (not shown) engages the stopper 40 and the lever 42 as shown in FIG. 7, thereby positioning the boppin chuck in the rotational direction. As shown in FIG. 6, the spur gears 34 and 36 are simultaneously disengaged by power (not shown). The rotary table 19 is rotated by a power not shown, and the unwound coil bobbin 9 is supplied. Hereinafter, this will be referred to as the end-of-winding operation. [Example B] Coil bobbin 9 having the axial terminal 6 shown in FIG.
The winding will be explained.

Perform preparatory movements.

As shown in FIG. 8, the air cylinder 66 is retracted, the guide nozzle 54 is rotated approximately 90 degrees, and the axial terminal 66 is rotated approximately 90 degrees.
Make it almost parallel to.

The following operations are continuously performed as shown in FIG. 16 while appropriately moving the guide nozzle 54 by arbitrarily rotating the stepping motor 52 in forward and reverse directions (guide nozzle movement amount ε). By rotating the fifth winding shaft 28, the axial terminal 6 moves in any direction relative to the guide nozzle 54 (winding shaft rotation amount b).

8. The guide nozzle 54 is moved up and down by the same amount in the opposite direction to 6.

By repeating the above operation an arbitrary number of times, the guide nozzle 5
4, when the axial terminal 6 is considered to be stationary, the wire 22 is wound around the axial terminal 6, drawing a trajectory as shown in FIG. As shown in FIG. 26, the guide nozzle 54 is raised (guide nozzle elevation amount η), and the guide nozzle 54 is moved (guide nozzle movement amount θ), and the air cylinder 66 is pushed to rotate approximately 90 degrees to form a radial terminal. 6
becomes almost parallel to The above is called winding B operation. Below, similar to example A, the cutter single movement, tap-in movement, wiring movement,
By repeating the winding operation, the tap-out operation, the winding B operation, and the cutter 1 operation, it is possible to wind the wire around many terminals many times.

Next, a winding end operation is performed.

[Example C]

Coil bobbin 9 with axial terminal 6 shown in FIG.
The winding of the wire will be explained.

Perform preparatory actions.

As shown in FIG. 17, the air cylinder 66 is retracted, the guide nozzle 54 is rotated 90 degrees, and the axial terminal 66 is rotated 90 degrees.
Make it almost parallel to.

By lowering the guide nozzle 54 (to the guide nozzle lowering amount), the distance from the axial terminal 6 is approximately equal to the eccentric shafts 79, 8.
Make it equal to the eccentricity d of 0. The winding shaft 28 is rotated so that the guide nozzle 54 is located on a line connecting the center of the winding shaft 28 and the axial terminal 6. The brake of the brake motor 90 is released, the rotation direction of the brake motor 90 is arbitrarily selected according to the direction of winding, and the brake motor 90 is rotated.
Accordingly, the cam input shaft 87 is rotated. When the cam input shaft 87 completes one rotation, it is braked by the brake of the brake motor 90 and stopped. As a result, the guide nozzle 54 rotates any number of times around the axial terminal 6, and the wire rod 22
Wrap it around the axial terminal 6. At this time, Katsuta 95
, 96 and the axial terminal 6 so as not to cut the wire 22 when the guide nozzle 54 rotates.
The positions of the guide nozzle 54 and the guide nozzle 54 are determined. In synchronization with the brake release signal of the brake motor 90, the guide nozzle 54 is appropriately moved forward or backward (guide nozzle movement amount ε) and stopped at the same time as the brake signal. Guide nozzle 54
The wire 22 is wound around the axial terminal 6 an arbitrary number of times while drawing the locus shown in FIG. Similar to the winding B operation,
As shown in Fig. 26, 54 is raised to the guide nozzle (
The guide nozzle 54 is moved by the guide nozzle rising amount η) (the guide nozzle moving amount θ), and the air cylinder 66 is pushed to rotate the guide nozzle 54 approximately 90 degrees to make it substantially parallel to the radial terminal 6. Winding above C operation and when O below A
Similar to the example, cutter one river action, tap in action, wiring action, winding action, tap out action, winding C action, cutter one
By repeating the operation, windings involving multiple turns on multiple terminals are possible.

Next, a winding end operation is performed.

Instead of rotating the winding shaft 28 and positioning the guide nozzle 54 on the line connecting the center of the winding shaft 28 and the axial terminal 6 in the above-described winding C operation, as shown in FIG. 62 and the air cylinder 63, and by selecting the stroke amount δ of the air cylinder 62, the guide nozzle 54 is swung around the slide shaft 49, and the guide nozzle 54 and the axial terminal 6 are moved.
The guide nozzle 54 is positioned so that the straight line connecting the two winding shafts 28 is perpendicular to the straight line connecting the two winding shafts 28.

An example of this positioning is shown at λ in FIG. The other operations are the same as those of the winding C operation. The operation of winding the wire 22 around the axial terminal 6 an arbitrary number of times by controlling as described above is called a winding D operation. A flowchart of the various operations described above is shown in FIG.

Although it has been explained above that the movement and vertical movement of the guide nozzle 54 and the rotation of the winding shaft 28 are driven by a stepping motor, other types of motors, such as digital Similar control is possible even if a DC servo motor is used as the control method. Further, although the synchronized rotation of the two eccentric shafts 79 and 80 has been explained using rotation of a motor via a cam, other methods can also be used.

A As shown in FIG. 19, 0n of the air cylinder 105,
0ff causes the cam output shaft 82 to rotate via the rack 106 and pinion 107.

Pinion 107 is fixed to cam output shaft 82. As a disadvantage, it is difficult to increase the speed due to the characteristics of the single air cylinder 105. The motion characteristics of two rotations are poor.

3. The direction of rotation cannot be selected arbitrarily.

B In the previous example, an electromagnetic clutch is provided between the pinion 107 and the cam output shaft 82, and the movement of the air cylinder 105 between 0n and 0ff can be arbitrarily selected.

In addition to the disadvantages of examples 1 and 2, the stopping position of the four-cam output shaft 82 is not guaranteed. 5. Even with de-energized braking, the holding torque may be small.

C As shown in FIG.
12. The power is transmitted to the cam output shaft 82 via gears 113 and 114, and positioning is performed by the engagement of a stopper 115 and a lever 116, and the power is provided by an air cylinder 117.

In this case, the disadvantages of 3, 4, and 5 are eliminated. 6. When stopped, an impact is generated due to inertia due to the stopper 115 and the lever 116.

7. Control at start and stop is complicated.

8 If the number of turns is small, it is difficult to increase the speed.

The winding by the cam configured as above is performed by the above-mentioned A, B,
Since the disadvantages of the C3 example can be eliminated, a single-loaded device can be rotated at high speed and smoothly when starting and stopping.

It has the advantage that it can be arbitrarily selected between two forward and reverse directions.

Therefore, when it is necessary to select the winding direction and the number of windings is relatively small, the device has higher productivity than the conventional method.

As shown in Figures 14, 16, and 17, the winding device of Example C above is capable of six types of winding: radial terminal winding I,..., axial terminal winding,... It is.

Since the switching between the radial terminal and the axial terminal is performed by setting the air cylinder 66 to 0n or 0ff, it can be arbitrarily controlled by an electric signal, and versatility can be expected. In winding I,,,, the amount of movement a of the guide nozzle, the amount of rotation b of the winding shaft, and the amount of vertical movement c of the guide nozzle can be arbitrarily set at the time of each winding, and it is suitable for winding around any shape of terminal. There are almost no restrictions. Among these, winding around rectangular terminals having a large length ratio is particularly advantageous. Since it is difficult to vary the winding V in a device having the same eccentricity d, the distance between the terminals that can be wound is determined from the size of the terminal. Therefore, it may be impossible to wrap a rectangular terminal with a large length ratio, but it is easy to wrap a terminal with a round pin or square pin, and the center of rotation of the guide nozzle can be moved from the center of the terminal. By selecting the vertical movement of the guide nozzle at an eccentric position, the interval between terminals that can be wound can be reduced.
Furthermore, since windings 5 and 6 use a cam system compared to other windings, they can be made faster and can be expected to improve productivity. The winding device of Example B is capable of four types of winding: winding I around the radial terminal, and winding around the axial terminal, as shown in FIGS. 14 and 16.
