The present invention relates to a coil winding machine that has an improved mechanism for regulating wire pitch and is capable of switching the combination of winding width and winding pitch set by each mechanism with a single touch.

BACKGROUND TECHNOLOGY A conventional coil winding machine, as shown in Fig. 6,
A main shaft 2 that rotates with a coil bobbin 1 fitted to its tip, a main shaft motor 3 that rotates the main shaft 2 in a fixed direction, and a tensioner 5 that applies tension to the wire 4 wound around the coil bobbin 1. , the main shaft 2 is attached to the tapered roller 6 provided at the base end.
It has a lead screw 9 to which rotational force is transmitted from a pulley 7 fixed to the root part via a belt 8, and the tensioner 5 is reciprocated within a winding width w relative to the coil bobbin 1 to wind the wire 4. traverser 10 for guiding.
The traverser 10 includes a movable support plate 11 screwed onto the screw shaft of the lead screw 9, a front detection switch 12 provided before and after the movable support plate 11 for setting and detecting the front end of the winding width w; It consisted of a rear detection switch 13 for setting and detecting the rear end, and a front clutch 14 and a rear clutch 15 such as electromagnetic clutches installed on the axis of the lead screw 9 and rotating the lead screw 9 in forward and reverse directions. . Further, an arm 16 extends from the movable support plate 11, and a tensioner 5 is provided at the tip of the arm 16 via a mounting plate 17. Furthermore, a belt hanging ring 18 is provided at the intermediate portion of the belt 8, which is hung between the pulley 7 of the main shaft 2 and the tapered roller 6 of the lead screw 9.
A lever 19 is attached to this belt hanging ring 18 to move it in a direction perpendicular to the belt 8. The belt retaining ring 18 and the lever 19 constitute means for regulating the winding pitch of the wire 4. In addition, in FIG. 6, the reference numeral 20
Reference numeral 21 indicates a control circuit for controlling the winding width, etc., and reference numeral 21 indicates a drive circuit for the main shaft motor 3 and the like.

In such a conventional coil winding machine, the operation of regulating the winding width w of the wire 4 on the coil bobbin 1 is performed as follows. First, the front detection switch 12 and the rear detection switch 13 are connected in accordance with the winding width w of the wire 4 on the coil bobbin 1.
are positioned and set in front and behind the movable support plate 11. Next, along with the winding operation of the wire 4 due to the rotation of the main shaft 2, the lead screw 9 of the traverser 10 is rotated in the direction of arrow A or B via the pulley 7, belt 8, and tapered roller 6, and as a result, the above-mentioned moving support is rotated. The plate 11 moves forward and backward along the axis of the lead screw 9 in the direction of arrow C or D. Then, when the front side or the rear side comes into contact with the front detection switch 12 or the rear detection switch 13, the respective detection switches 12 and 13 operate and send out the detection signal S ₁ or S ₂ to the control circuit 20. The control circuit 20 sends a drive signal S ₃ to the drive circuit 21 in response to each detection signal S ₁ , S ₂ .
Or send out S ₄ . Next, this drive circuit 21 inputs the respective drive signals S ₃ and S ₄ and sends a control signal S ₅ to the front clutch 14 or a control signal S ₆ to the rear clutch 15 to control the front clutch. 14 or the rear clutch 15 are respectively set to "disengaged" to stop the rotation of the lead screw 9 in the direction of arrow A or in the direction of arrow B, and at the same time, by another control signal, the clutch on the opposite side to the "disengaged" clutch is The clutch is "engaged" and the gears are in a reverse rotation state. This results in
This time, the lead screw 9 rotates in the direction of arrow B or A in the opposite direction as before, and as a result,
The movable support plate 11 moves backward and forward in the direction of arrow D or C along the axis of the lead screw 9. Thereafter, by repeating such operations, the front detection switch 12 and the rear detection switch 1
3, the movable support plate 11 moves forward and backward. Therefore, the tensioner 5, which is provided on the movable support plate 11 via the arm 16 and the mounting plate 17, reciprocates within a certain range with respect to the coil bobbin 1.
The front detection switch 12 and the rear detection switch 13 are used to connect the wire 4 to the coil bobbin 1.
Since the wire 4 is positioned in accordance with the winding width w, the winding width w of the wire 4 is regulated by the above operation.

Further, in order to regulate the winding pitch of the wire 4 with respect to the coil bobbin 1, the lever 19 is operated in the direction of the arrow E or the direction of the arrow F.
may be shifted by a predetermined amount in a direction perpendicular to the belt 8. Then, the belt 8 against the tapered roller 6
The winding position of the belt 8 moves in the direction of the arrow G or H, and the belt 8 is wound around the belt 8 at a position having a diameter corresponding to a predetermined winding pitch set by the lever 19. That is, the ratio of the diameter of the tapered roller 6 of the lead screw 9 to the diameter of the pulley 7 of the main shaft 2 changes. When the winding operation is started in this state, the lead screw 9 rotates in the direction of the arrow A or B, and the rotation speed changes depending on the position of the belt 8 around the tapered roller 6. That is, when the belt 8 moves in the direction of the arrow G and is wound around, the rotation speed becomes slow, and conversely, when it moves in the direction of the arrow H and is turned around, the rotation speed becomes faster. Since the rotational speed of the lead screw 9 changes in this way, the moving speed of the movable support plate 11 screwed to the lead screw 9 in the directions of arrows C and D also changes to the rotational speed of the lead screw 9. Therefore, it becomes slower or faster.
Therefore, the reciprocating speed of the tensioner 5 relative to the coil bobbin 1 also changes, and the winding pitch of the wire 4 relative to the coil bobbin 1 changes. That is, when the belt 8 moves in the direction of arrow G relative to the tapered roller 6 and is wrapped around it, the winding pitch becomes smaller, and conversely, when it moves in the direction of arrow H and is wrapped around it, the winding pitch becomes smaller. becomes larger.
In the manner described above, the winding pitch of the wire 4 is regulated.

Problems to be Solved by the Invention However, in such a conventional coil winding machine, the winding width w of the wire 4 on the coil bobbin 1 is regulated by the positional interval between the front detection switch 12 and the rear detection switch 13. Therefore, when changing the winding width w of the wire 4 to correspond to a coil bobbin 1 etc. of a different size, move the positions of the front detection switch 12 and the rear detection switch 13, respectively, and make a new winding. It was necessary to position it at a location corresponding to the width w and reset it. Therefore, the work of adjusting the winding width w of the wire 4 is complicated, and it is difficult to adjust it correctly. Furthermore, a mechanism for moving and fixing the front detection switch 12 and the rear detection switch 13 (not shown) is required, making the structure of the traverser 10 complicated. On the other hand, regarding the winding pitch, lever 19
is set by operating in the direction of arrow E or F, so a pitch scale plate is provided on the side of the lever 19, a cursor is moved and fixed along this pitch scale plate, and the lever 19 is moved to this cursor. Lever 1 requires some ingenuity, such as abutting and fixing with a spring, etc.
The structure around 9 was complicated. Also,
The lever 19 may not be securely fixed.
The winding pitch could not be set accurately, and the winding pitch sometimes changed due to vibrations during operation. Furthermore, since the setting was performed entirely mechanically using the lever 19, it was not possible to set or change the winding pitch electrically. Furthermore, the winding width w of the wire 4 is set,
The operation of changing the winding pitch and the operation of setting and changing the winding pitch must be adjusted separately at different positions around the traverser 10, and the winding width and winding pitch can be set and changed by switching with a single touch. I couldn't do it. Therefore, the operability was poor. Therefore, an object of the present invention is to solve such problems.

Next, the operation of regulating the winding width w and the winding pitch in the coil winding machine configured as described above will be explained. First, the first leading end winding width setting means 31 and the first trailing end winding width setting means 32 shown in FIG. 2 are adjusted to set the winding width w within a predetermined range. That is, by turning the knob of the variable resistor serving as the first front end winding width setting means 31, set a resistance value of 2KΩ corresponding to, for example, 2 cm in FIG. 4, and set the front end of the winding width w shown in FIG.

Set 9KΩ and set the rear end of the winding width w.
As a result, a range from 2 cm to 9 cm within the winding width setting range is set as the winding width w. Similarly, the second front end winding width setting means 33 and the second trailing end winding width setting means 34 are adjusted to obtain a winding width w different from the above value.
Set.

At the same time, the first pitch setting means 49 shown in FIG. 2 is adjusted to set a desired winding pitch.
That is, by turning the knob of the variable resistor serving as the first pitch setting means 49, a resistance value of 5KΩ corresponding to, for example, the winding pitch _p1 in FIG. 5 is set. As a result, _p1 of the pitch setting range shown in FIG. 5 is set as one winding pitch.
Similarly, the second pitch setting means 50 is adjusted to set a value different from the above, for example, a resistance value of 7KΩ corresponding to the winding pitch _p2 to set the winding pitch _p2 . Then, in this state, the switching means 53 shown in FIG. 2 is operated, and each contact piece 54, 55, 56
are linked to switch to one side of contacts a, c, and e with a single touch. Thereby, the winding width w set by the set of the first leading end winding width setting means 31 and the first trailing end winding width setting means 32 and the first pitch setting means 49
The combination of winding pitch p ₁ set in is selected.

Next, in this state, the start button 57 shown in FIG. 1 is pressed to start the operation of the entire apparatus, and the wire 4 supplied via the tensioner 5 is wound around the wire bobbin 1 by rotation of the main shaft 2. Along with this winding operation, the lead screw 9 of the traverser 10 rotates in a certain direction, for example, in the direction of arrow A, through the pulley 7 and belt 8 provided on the main shaft 2, and the tapered roller 6, and as a result, the movable support plate 11 rotates in the direction of arrow A. It moves forward along the axis of the lead screw 9, for example in the direction of arrow C. At this time, as the lead screw 9 rotates in the direction of arrow A, the pulley 2
9 also rotates in the same direction, belt 30 and pulley 28
The rotating shaft 27 of the winding width detecting means 26 is rotated through the winding width detecting means 26. Then, the wiper of the winding width detection means 26 slides on the resistance element, and its resistance value changes according to the characteristic curve shown in FIG. This change in resistance value is output as a detection signal S ₇ of the amount of rotation of the lead screw 9, and this detection signal S ₇ is sent to the front end winding width comparator 35 and the rear end winding width comparator 35 in the control circuit 20 shown in FIG. Each is input to one terminal of the width comparator 36. Here, a signal _S8 corresponding to a resistance value of 2KΩ set in the first front end winding width setting means 31 is inputted to the other terminal of the front end winding width comparator 35 via a contact a. A signal _S9 corresponding to the resistance value of 9KΩ set in the first trailing end winding width setting means 32 is connected to the other terminal of the trailing end winding width comparator 36 at contact c.
I am entering it through.

Then, when the lead screw 9 rotates by a certain amount, the resistance value of the winding width detecting means 26 becomes, for example, 2K.
Ω, the detection signal S ₇ of the winding width detection means 26 input to the leading end winding width comparator 35 and the output signal S ₈ from the first leading end winding width setting means 31 match,
This front end winding width comparator 35 sends out a coincidence signal _S10 . This coincidence signal S ₁₀ is then input to the forward switching driver 37 , which sends out a driving signal S ₁₁ to the driving circuit 21 . This drive signal
The control relay in the drive circuit 21 is actuated by the input of _S11 , and the drive circuit 21 operates as shown in FIG.
A control signal _S12 is sent to the front clutch 14. Then, the front clutch 14 is "disengaged" and the rotation of the lead screw 9 in the direction of arrow A is stopped, and the forward movement of the movable support plate 11 in the direction of arrow C is stopped.

At the same time, the rear clutch 15 is brought into "contact" by another control signal, and the gears are brought into a state of reverse rotation. As a result, the lead screw 9 now rotates in the direction of arrow B in the opposite direction, and as a result, the movable support plate 11 retreats in the direction of arrow D along the axis of the lead screw 9. If the lead screw 9 is rotated in the opposite direction by a certain amount and the resistance value of the winding width detecting means 26 becomes, for example, 9KΩ, then in FIG. The detection signal S 7 of the width detecting means ₂₆ and the output signal S ₉ from the first trailing end winding width setting means 32 match, and the trailing end winding width comparator 36 sends out a coincidence signal S ₁₃ . Then,
This coincidence signal _S13 is input to the rear switching driver 38,
This rear switching driver 38 sends a drive signal S ₁₄ to the drive circuit 21 . The control relay in the drive circuit 21 is actuated by the input of this drive signal _S14 , and the drive circuit 21 is connected to the rear clutch 1 as shown in FIG.
A control signal S ₁₅ is sent to 5. Then, the rear clutch 15 is disengaged, and the lead screw 9 stops rotating in the direction of arrow B, and the moving support plate 11 stops moving backward in the direction of arrow D. At the same time, the front clutch 14 is brought into "contact" by another control signal, the meshing of the gears is brought into a state of forward rotation, and the lead screw 9 is again moved in the direction indicated by the arrow
The rotating support plate 11 moves forward in the direction of arrow C.

Thereafter, by repeating the above-mentioned operation, the lead screw 9 rotates forward and backward within a predetermined range, and the moving means plate 11 moves forward and backward within a certain range on this lead screw 9, and this moving support plate The tensioner 5, which is provided on the coil bobbin 1 through an arm 16 and a mounting plate 17, is controlled to reciprocate within a certain range with respect to the coil bobbin 1. The resistance values of the first front end winding width setting means 31 and the first rear end winding width setting means 32 are set to values corresponding to the front end or rear end position of the winding width w, respectively. Through the above operations, the winding width w of the wire 4 is regulated to a predetermined value.

Simultaneously with this regulating operation of the winding width w, the pitch changing motor 41 of the belt moving means 39 is driven,
The rotary screw shaft 42 rotates in a predetermined direction, and the support plate 43 moves forward in a predetermined direction, for example, in the direction of arrow E. Then, the belt retaining ring 44 protruding from the support plate 43 also moves forward in the direction of arrow E, pushing the belt 8 in the right angle direction. As a result, the position of the belt 8 around the tapered roller 6 moves in the direction of arrow G, for example. At this time, as the rotating screw shaft 42 of the pitch changing motor 41 rotates, the pulley 4
7 also rotates in the same direction, belt 48 and pulley 46
The rotating shaft 45 of the pitch detecting means 40 is rotated through the pitch detecting means 40. Then, the wiper of the pitch detection means 40 slides on the resistance element, and its resistance value changes according to the characteristic curve shown in FIG. This change in resistance value is output as a detection signal S ₁₆ of the amount of rotation of the rotating screw shaft 42, and this detection signal S ₁₆ is output as the second detection signal S 16.
The signal is input to one terminal of a pitch comparator 51 in the control circuit 20 shown in the figure. Here, the other terminal of this pitch comparator 51 receives a signal S ₁₇ corresponding to the resistance value of 5KΩ set in the first pitch setting means 49.
is input via contact e.

Then, when the rotating screw shaft 42 rotates by a certain amount, the resistance value of the pitch detection means 40 becomes, for example, 5KΩ.
, the detection signal S ₁₆ of the pitch detection means 40 input to the pitch comparator 51 and the output signal S ₁₇ from the first pitch setting means 49 match, and this pitch comparator 51 outputs the match signal S Send out ₁₈ . Then, this coincidence signal S ₁₈ is input to the motor driver 52, and this motor driver 52 sends a drive signal S ₁₉ having the content "motor stop" to the pitch changing motor 41. Upon input of this drive signal _S19 , the pitch changing motor 41 stops rotating. As a result, the rotating screw shaft 42 stops rotating in a predetermined direction, and the support plate 43 also stops moving forward in the direction of arrow E, and the belt hook ring 44 protruding from the support plate 43 is also held at that position. Stop pushing against. Therefore, the movement of the belt 8 around the tapered roller 6 in the direction of arrow G is also stopped, and the belt 8 is fixed at that position. As a result, the ratio of the diameter of the tapered roller 6 of the lead screw 9 to the diameter of the pulley 7 of the main shaft 2 is fixed at a certain value, and the rotation of the lead screw 9 causes the tensioner 5 to reciprocate with respect to the coil bobbin 1. The movement speed of movement is determined to a certain value. As a result, the winding pitch of the wire 4 with respect to the coil bobbin 1 is regulated to the initially set value _p1 .

Next, in order to change the winding width w and the winding pitch _p1 , operate the switching means 53 shown in FIG. All you have to do is switch to the d and f sides with a single touch. As a result, the winding width w of another value set by the pair of the second front end winding width setting means 33 and the second rear end winding width setting means 34 and the winding pitch set by the second pitch setting means 50 are set. A combination of p ₂ is selected.
