DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a winding device,
In particular, the present invention relates to a winding device equipped with a mechanism for stripping an insulating film of a wire.

[0002]

2. Description of the Related Art Generally, when winding a wire around a bobbin, the wire is wound around a terminal of the bobbin at the beginning or end of winding, and is welded to the terminal. Then, the insulating coating of the wire to be entangled can be peeled off in advance, so that the reliability of the joining between the terminal and the wire can be increased. The peeling device for the insulating coating is attached to the winding device.

[0003] However, the insulating film peeling device in the conventional winding device is separate from the winding machine, is disposed at a site for supplying a wire to the winding machine, and is far from the feeding portion at the tip of the flyer. Was located away.

[0004] Therefore, when the length to be wound by the end of the winding becomes equal to the distance between the stripping position of the wire and the feeding portion, the insulating coating of the wire passing through the stripping device is stripped, and the stripped portion is wound. When the wire portion is conveyed toward the feeding portion and the wire portion finishes winding the wire and moves to the terminal, the peeled portion of the wire that has been peeled off is fed from the feeding portion.

[0005]

However, in the above-mentioned conventional winding device, the wire passing through the peeling device starts peeling in anticipation of the winding end position on the bobbin. As we progress toward the end of the book,
Due to the change in the winding circumference or the winding density, it is difficult to accurately match the peeled portion to the terminal entanglement position, and often the wire portion that has not been peeled is entangled with the terminal. During the soldering and welding, there was a problem that the scum of the insulating coating carbonized scattered around and adhered to the terminals.

[0006] In particular, when the position of the insulating film peeling device and the position of the winding and feeding portion are largely apart, the above-mentioned deviation is more likely to occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a winding device suitable for accurately wrapping a stripped portion of an insulating film around a terminal of a bobbin.

[0008]

According to a first aspect of the present invention, a wire feeder for feeding a wire is provided at a distal end position eccentric from an axis, and is rotatably supported by a rotary head. A winding flyer, a peeling mechanism disposed in a wire passing path in front of a feeding portion of the flyer, and a peeling mechanism for peeling off an insulating film of a wire passing therewith with rotation of a rotating shaft, selectively coupled to the peeling mechanism. And driving means for driving the rotating shaft to rotate.

According to a second aspect of the present invention, in the first aspect, the peeling mechanism includes a weight that presses a cutter, which is disposed on the rotating shaft and can come into contact with and separate from the wire, toward the wire by centrifugal force accompanying rotation, and the cutter. It is characterized in that a spring is provided which urges against the centrifugal force in a direction away from the wire.

[0010] In a third aspect based on the first or second aspect, the rotary head is supported by a three-axis moving means so as to be movable in three axial directions. It is characterized by being movable in the axial direction.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the driving means of the peeling mechanism is a roller fixed to a rotating shaft, and is rotated by a driving source and is capable of coming into contact with and separating from the roller. And a simple driving roller.

According to a fifth aspect of the present invention, in any one of the first to third aspects, the driving means of the peeling mechanism is rotatably disposed coaxially with a rotary member fixed to a rotary shaft and a flyer. It comprises a ring member engaged with the rotating member, and a drive source provided on the rotating head for rotating the ring member relative to the flyer.

According to a sixth aspect of the present invention, in the third aspect, the peeling width of the peeling mechanism is such that the width of the wire in the four-axis direction of the payout portion with respect to the wire rod locked to the fixing member via the payout portion of the flyer. It is characterized by being adjusted by at least one axial movement amount.

[0014]

Therefore, in the first invention, a peeling mechanism for peeling off the insulating film of the wire with the rotation of the rotating shaft is provided in the wire passage path before the feeding portion of the flyer, and the peeling mechanism is rotated by the driving means. Since the actuator is driven, the distance between the peeling position and the feeding portion where the wire is entangled is reduced, and when the peeling portion of the insulating coating is fed from the feeding portion, it can be accurately matched to the terminal position of the work, and the Soldering, welding, etc. of the wire can be performed reliably.

Therefore, as in the conventional case, the wire is not accurately positioned at the position of the terminal because the wire is loosened or stretched on the way to the feeding portion after peeling. It is possible to solve the problem that it is not possible to determine accurately and it is difficult to perform accurate positioning.

In addition, since the peeling means peels off the insulating coating while rotating, the insulating coating on the entire circumference of the wire can be peeled off, so that the soldering and welding to the terminal can be more reliably performed.

In the second invention, in addition to the effect of the first invention, a weight for pressing a cutter capable of bringing the separation mechanism into and out of contact with the wire toward the wire by centrifugal force accompanying rotation, and separating the cutter from the wire. And a spring mechanism that urges the cutter against the centrifugal force in the direction, so that the rotating shaft is rotated by the driving means, and the cutter acts toward the wire rod by the centrifugal force applied to the weight. Is received by a spring mechanism that urges the cutter so as to oppose the above, and the cutter moves to a position where both are balanced. When the rotation speed of the driving means is increased, the balance position changes to a position closer to the axis of the wire. Therefore, the position of the cutter during rotation can be adjusted by adjusting the rotation speed of the driving means. And, by changing the rotation speed of the driving means in accordance with the wire diameter of the wire, it is possible to prevent an excessive pressing force from being applied to the wire during the peeling operation, and it is possible to prevent the wire from being cut or shaving off the wire, etc. Only the insulating film made of the resin layer having a soft surface can be peeled off. Therefore, even when the wire is thin, the insulating coating can be peeled off without breaking.

According to the third invention, in addition to the effects of the first or second invention, since the feeding portion is movable in four axial directions including rotation of the flyer, the wire rod having one end locked to the work is provided. When the wire is fed from the feeding portion, it is only necessary to move the feeding portion to any one of the four axes, and the wire is moved by moving the feeding portion even when the insulating coating of the wire is peeled at a predetermined length. And does not require a separate feeding mechanism to feed the wire.

In the fourth aspect of the present invention, since the driving means of the peeling mechanism is provided separately and comes into contact with the roller of the peeling mechanism only when necessary to operate the peeling mechanism, the rotating portion of the flyer can be lightened, The positioning accuracy and the movement position accuracy can be improved, and the driving force can be reduced.

In the fifth invention, since the driving means of the peeling mechanism is always connected to the peeling mechanism, the insulating film of the wire can be peeled at any rotational position of the flyer, the peeling position can be set arbitrarily, and the peeling position can be set. Accuracy can be further improved.

According to a sixth aspect of the present invention, in addition to the effect of the third aspect, since the peeling width of the peeling mechanism is adjusted by the amount of movement of the feeding portion in at least one of four axial directions, positioning of the flyer is performed. The separation width can be adjusted with the precision corresponding to the precision.

Next, the winding operation of the winding device will be described.

First, the wire A is rotated by the rotating body 25 of the flyer 28.
Guided by the guide pulley 25B from the wire introduction hole 25A of
With the guide pulley 28 </ b> E and the feeding portion 27 passing through the inside of the rotating shaft 9 of the peeling mechanism 1, the tip is entangled with the pin 37 of the discarding entanglement portion 5. This entanglement operation is performed when the preceding winding work on the work W is completed.

Next, the output shaft SH on the output side of the rotor, which is the work W, is attached to the chuck jig 32 of the indexing table 31.
The indexing motor 30 is operated to position the magnetic pole between the slots S of the wire A at the indexing position so as to face the flyer 28. This work W
May be automatically performed by a manipulator (robot device) (not shown), and the first indexing operation may be omitted by determining the rotational position and mounting.

Next, the flyer 28 is moved closer to the work W by operating the three-axis moving means 20, and the feeder 27 at the tip of the flyer 28 is moved toward the terminal W1 of the commute overnight CM.

Along with the movement of the flyer 28, the wire A, the tip of which is tied to the pin 37 of the tying portion 5, is passed through the peeling mechanism 1 and is fed out of the feeding portion 27, and at a predetermined timing, the stripping motor is moved. The drive roller 17A driven by the roller 17 is moved down by the upper and lower cylinders 16A so as to come into contact with the rotating roller 10 of the peeling mechanism 1 to drive the rotating shaft 9 of the peeling mechanism 1.

This rotation causes the shaft 12 supported by the large and small disks 11A and 11B to rotate (revolve), and the shaft 12 to rotate according to the centrifugal force applied to the weight 14 at the rear end of the shaft 12.
Is rotated by a predetermined angle, and the cutter 1 at the tip of the shaft 12 is rotated.
Then, the insulating film on the surface of the wire A is peeled off in a helical manner by each of the cutters 13.

When the peeling of the predetermined range is completed, the peeling motor 1
The drive roller 7 and the drive roller 17A are lifted by the lift cylinder 16A and separated from the rotating roller 10 of the peeling mechanism 1, and the film peeling ends.

The position and range of the peeling range are set so that the wire A peeled from the feeding portion 27 when the feeding portion 27 of the flyer 28 comes closest to the terminal W1 is fed. Is measured in advance, the peeling position is set, the peeling range is set within the range of the length entangled with the terminal W1, and the peeling range is input to the program, respectively, and the peeling motor 17 and the driving roller 17A are moved up and down. I have to.

When the wire A hangs on the terminal W1, the feeding portion 27 of the flyer 28 is turned around the terminal W1 by the three-axis moving means 20, and the peeled portion of the wire A is entangled with the terminal W1. The flyer 28 is moved by the three-axis moving means 20 and the receiving portion 28 of the center former 29 is moved.
B is brought into contact with the outer periphery between the throats S on the side of the armature AM.

In this state, the outer periphery of the center former 29 has a shape continuous with the slot S of the work W.
The center of the magnetic pole and the center of the flyer 28 face each other.

Next, the slot S of the magnetic pole of the work W
In order to wind the wire A around the magnetic pole slot, the flyer motor 26A is rotated, the rotating body 25 is rotated via the pulleys 26B and 26C, and the belt 26D, and the feeding portion 27 of the flyer 28 is rotated and moved around the magnetic pole. The wire A is wound around S.

In this winding operation, the center former 29 is supported by the flyer 28 by the bearing 29A.
The wire A fed from 7 is guided to the slot S of the work W.

When a predetermined number of turns are wound, the peeling mechanism 1 is positioned upward, the rotation of the flyer 28 is stopped, and the peeling motor 17 and the driving roller 17A are lowered by the vertical cylinder 16A. Rotating roller 1
0, the cutter 13 of the peeling mechanism 1 is rotated around the wire A by rotating the peeling motor 17, and the cutter 13 is brought into contact with the wire A by the centrifugal force of the weight 14 to insulate the wire A. Peel off the coating.

In conjunction with the operation of the peeling mechanism 1, the flyer 28 is retracted (moved) by a predetermined amount by operating the forward / backward moving mechanism 23 (either the left / right moving mechanism 21 or the up / down moving mechanism 22) of the three-axis moving means 20. By doing so, the insulating film having a predetermined width of the wire A can be peeled off. After the insulating film having the predetermined width has been peeled off, the peeling motor 17 is raised and the peeling mechanism 1 is stopped.

Next, the indexing table 31 is rotated by a predetermined angle by the indexing motor 30 for the rotor serving as the workpiece W, and is positioned at a winding position on a magnetic pole to be newly wound.

Then, the feeding portion 27 is made to approach the terminal W1 of the commuting overnight CM corresponding to the new magnetic pole, the wire A is hung on the terminal W1, and the feeding portion 27 of the flyer 28 is connected to the terminal W1.
It is moved around the terminal W1 by the shaft moving means 20, and the terminal W
1 and wire A.

At this time, the exfoliated portion of the wire A is
The feeding portion 27 and the cutter 13 of the peeling mechanism 1 are separated from each other so that the insulating film is peeled from the position corresponding to the distance between the end of winding of the wire A and the terminal W1 to be entangled this time so as to be fed from the tip. The separation start position and the separation end position during the predetermined stroke of the front-rear movement mechanism 23 are set in consideration of the interval (the movement mechanism in another direction may be used).
The wire A can be entangled with the terminal W1 at the peeled portion.

Then, the flyer 28 is rotated with the flyer 28 facing the magnetic pole, wound around the magnetic pole slot S by a predetermined number of turns by the guide of the center former 29, and the insulating film is similarly peeled off.
Is rotated by a predetermined angle by the indexing motor 30 to move the new magnetic pole to the winding position, and the feeding unit 27 is entangled with the terminal W1 of the commute overnight CM corresponding to the new magnetic pole. The peeled portion of the wire A is entangled with the terminal W1.

By repeating the above operation, the wire A is sequentially wound around the slot S of the work W, and the wire A is wound around the terminal W1.
When the winding of the armature AM is completed, the flyer 28 moves the feeding portion 27 around the tying pin 37 by the three-axis moving means 20 to wrap the wire A around the tying pin 37, and the flyer 28 28 is stopped.

Then, the welding head 35 is moved to the three-axis moving mechanism 3.
6, the terminal W1 of each entangled commutator CM is welded to the wire A, and a series of operations is completed. The work W is removed from the chuck 32 and transported to the next step.

The above embodiment has the following effects.

The peeling mechanism 1 includes a hollow rotary shaft 9 rotatable by the flyer 28, extending toward the rear end of the feeding portion 27, and selectively rotating with the external driving means 7 to rotate. 9 is composed of the insulating film peeling means 13 which surrounds the wire A guided from the leading end to the rear end of the feeding portion 27 and moves close to the wire A by rotation of the rotating shaft 9 to peel off the insulating coating of the passing wire A. The distance between the position and the feeding portion 27 for feeding the separated wire A can be shortened, and when the separated portion of the wire is fed from the feeding portion 27, the position of the terminal W1 of the work W can be accurately matched with the position of the terminal W1. Soldering and welding of the wire A can be performed reliably.

Therefore, as in the prior art, the wire after peeling off the film is loosened or stretched while moving to the feeding portion, and the peeled portion is not accurately positioned at the terminal position, or is not aligned and wound. In this case, it is possible to solve the problem that the length of the wire cannot be accurately determined, and that accurate positioning is difficult.

Since the peeling means 13 peels off the insulating coating while rotating around the wire A, the insulating coating on the entire circumference of the wire A can be peeled off, and the soldering and welding to the terminal W1 can be performed more reliably. Can be.

Further, a weight 14 for pressing the cutter 13 capable of bringing the peeling mechanism 1 into and out of contact with the wire A toward the wire A by centrifugal force accompanying rotation, and opposing the centrifugal force in a direction in which the cutter 13 is separated from the wire A. And the spring mechanism 15 that urges the rotating shaft 9 to rotate.
The centrifugal force applied to the weight 14 acts to press the cutter 13 toward the wire rod A, and this pressing force is received by a spring mechanism 15 that urges the cutter 13 to oppose this, and is moved to a position where both are balanced. The cutter 13 moves. When the rotational speed of the driving means 7 is increased, the balance position changes to a position closer to the axis of the wire A. Therefore, the position of the cutter 13 during rotation can be adjusted by adjusting the number of rotations of the driving means 7. By changing the rotation speed of the driving means 7 according to the wire diameter of the wire A, it is possible to prevent the wire A from being subjected to an excessive pressing force during the peeling operation, and to prevent the wire from being broken or the wire being cut off. It is possible to peel off only the insulating film made of the resin layer having a soft surface. Therefore, even when the wire A is thin, the insulating film can be peeled without breaking.

Further, since the feeding portion 27 is provided so as to be movable in four axial directions including the rotation of the flyer 28 by the three-axis moving means 20, the wire A having one end locked to the work W is fed from the feeding portion 27. At the time of dispensing, it is only necessary to move the dispensing portion 27 to any of the four axes, and even when the insulating coating of the wire A is peeled off at a predetermined length, the dispensing portion 27 can be moved to move the wire A. A separate feeding mechanism is not required for feeding the wire A.

Further, since the peel width of the wire A can be adjusted by the amount of movement of the feeding portion 27 in at least one of the four axial directions, the peel width can be adjusted with an accuracy corresponding to the positioning accuracy of the flyer 28.

Further, since the peeling mechanism 1 is provided with the peeling motor 17 and the drive roller 17A as the driving means 7 separately, the rotating portion of the flyer 28 can be reduced in weight, and its positioning accuracy and moving position accuracy are improved. And the driving force can be reduced.

FIG. 4 is a perspective view of a winding device according to another embodiment of the present invention, and FIG. 5 is a front view thereof. In the winding device shown in FIGS. The driving means 7 has a restriction that the peeling mechanism 1 can be driven only by the driving means 39. In the present embodiment, however, the driving means 39 is capable of removing the restriction and operating the peeling mechanism 1 at any time regardless of the rotational position of the flyer 28. In Figure 1
The same parts as those of the winding device shown in FIG.

That is, the rotary roller 10 of the peeling mechanism 1 is changed to a bevel gear 40 (not only straight teeth but also curved teeth), and the ring gear 4 having teeth meshing with the bevel gear 40 is used.
1 is rotatably supported on the outer periphery of the rotating body 25 via a bearing 43, and a pulley 44 is provided integrally with the ring gear 41,
A drive pulley 46 of a peeling motor 45 with a built-in clutch (not shown) fixed to the rotary head 24 and a pulley 44 of the ring gear 41 are wound around a belt 47.

By releasing the clutch built in the peeling motor 45, the ring gear 41 rotates integrally with the rotating body 25 without changing the meshing position between the ring gear 41 and the bevel gear 40. The belt 47 and the pulleys 44 and 46 can be in an idling state, so that the peeling mechanism 1 is not operated.

When the peeling mechanism 1 is operated,
By driving the peeling motor 45 by fastening the built-in clutch to the peeling motor 45, the ring gear 41 is rotated relative to the rotating body 25 via the belt 47, and the meshing bevel gear 40 is rotated, and the flyer The rotation shaft 9 can be rotated without being restricted by the rotation position 28.

In the above example, the bevel gear 40 and the ring gear 41 are combined. However, the present invention is not limited to this. For example, a combination of a pinion gear and a ring gear and a combination of a friction roller and a ring roller may be used. You may.

In this embodiment, in addition to the effects obtained by the embodiment shown in FIG. 1, the peeling mechanism 1 is constantly connected to the ring gear 41 as a ring member and the peeling motor 45 via pulleys 44 and 46. Because of the connection, the peeling mechanism 1 can peel off the insulating coating of the wire A at any rotational position of the flyer 28, and can set the peeling position arbitrarily.
The peeling position accuracy can be further improved.
