DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coil processing apparatus which can perform winding, winding of an interlayer tape, and winding of a barrier tape by a single unit.

[0002]

2. Description of the Related Art For processing a coil, it is necessary to provide a winding for winding the coil material around the coil bobbin and an interlayer tape tape for insulating between layers of the coil material. Taping of a thin barrier tape that is rolled along is required. Heretofore, these operations have been performed separately by dedicated devices or manually. That is, in the related art, it is necessary to repeat the work of attaching and detaching the coil bobbin to and from the winding device and the taping device several times before processing of one coil is completed. With the increase, the work efficiency was greatly reduced.

To cope with such a problem, an example in which winding and taping can be performed by a single device is disclosed in Japanese Unexamined Patent Publication No. Sho.
Known as 3-280404. This JP
The winding machine of No. 3-280404 is provided with a tape winder, and a winding and an interlayer tape (exterior tape and inner tape).
Can be repeated alternately. Therefore, it is not necessary to attach and detach the coil bobbin each time for taping the winding and the interlayer tape, and it is possible to greatly improve work efficiency.

[0004] However, since this apparatus only has a tape winder for an interlayer tape, processing of a coil requiring a barrier tape is still insufficient.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a coil processing apparatus which can collectively perform winding, taping of an interlayer tape, and taping of a barrier tape by one apparatus. In addition, the object of the present invention is to make it possible to collectively perform three types of work in this way, thereby making it possible to more stably perform each type of work, especially two types of taping, to further improve the overall work efficiency. An object of the present invention is to provide a coil processing device that can be improved.

[0006]

The coil machining apparatus according to the present invention can rotate the held coil bobbin for winding and taping, and can traverse the coil bobbin in a direction parallel to the rotation axis for the winding. The above-mentioned structure is provided integrally with a bobbin rotating mechanism, an assembly for an interlayer tape for taping an interlayer tape on a coil bobbin, and an assembly for a barrier tape for taping a barrier tape on a coil bobbin.

[0007] This coil processing apparatus performs winding with a predetermined width by performing a traverse motion while a coil bobbin rotates. Therefore, accurate winding can be performed only by supplying the coil material in a state where it is regulated at a certain feeding point. On the other hand, each tape of the interlayer and the barrier is formed by winding the tape supplied from each assembly by the rotation of the coil bobbin. Then, these processes are sequentially performed in combination according to the design of the coil to be processed.

In the case of such a structure in which the three types of processing are performed collectively, the periphery of the coil bobbin is complicated. Therefore, if the bobbin rotation mechanism is configured so that the coil bobbin can be moved back and forth to be selectively positioned at the taping position and the winding position, the taping position and the winding position are separated, and the above-mentioned complicated Can be eliminated, so that workability can be improved.

The guide mechanism for regulating the coil material to be supplied to the coil bobbin to the above-mentioned constant feeding point may use a mechanism provided in a coil material bobbin device which is a supply source of the coil material. The coil processing device itself may be provided as necessary.

The interlayer tape assembly of the coil processing apparatus as described above includes a reel holding means for rotatably holding the tape reel, a holding means for holding the leading end of the tape from which the tape reel has been drawn, and a moving reel holding means. Reel moving means for reciprocating between a reference position and a setting position for setting the tape on the coil bobbin, and swinging up and down at the setting position to thereby move the leading end of the tape to the coil bobbin. By moving the tape reel rearward by reel moving means in a state where the tape tip is pressed against the coil bobbin,
If the tape is forcibly fed out by a predetermined length from the tape reel, and the rolled-out portion is wound around the coil bobbin, taping of the interlayer tape can be performed more stably.

That is, at the time of winding on the coil bobbin,
When the resistance for peeling the tape from the tape reel is directly applied, it is easy to cause a trouble that the tape tip portion temporarily attached to the coil bobbin is peeled off. Is forcibly peeled off from the tape reel and fed out, so that the above trouble can be effectively prevented.

The above-described barrier tape assembly of the coil processing apparatus includes a supply mechanism for supplying the tape from the held tape reel and a setting mechanism for setting the leading end of the tape supplied by the supply mechanism to the coil bobbin. A setting mechanism performs a first reciprocating motion between a reference position and a gripping position for gripping the leading end of the tape, and a second reciprocating motion in a direction intersecting the first reciprocating motion starting from the reference position. Is performed for setting the leading end of the tape to the coil bobbin, and the supply mechanism moves the gripping position for holding the leading end of the tape by the setting mechanism and the winding position for winding the tape by the coil bobbin. If the third reciprocating motion is performed in the same direction as the two reciprocating motions, taping of the barrier tape is performed. More stably performed.

That is, by adopting such a configuration,
Prior to the winding by the rotation of the coil bobbin, the leading end of the tape can be temporarily attached to the coil bobbin substantially half way around, so that the peeling as described above can be performed without performing a forcible peeling in advance like an interlayer tape assembly. Troubles can be reliably prevented, and thin and difficult-to-handle barrier tapes can be stably processed.

Further, in the above-described barrier tape assembly, while the setting mechanism is attached to the first base plate via the slide shaft, the supply mechanism is fixedly provided on the second base plate, and the slide shaft is connected to the second base plate. The first and second base plates are moved forward and backward by the one cam mechanism for the first reciprocating motion on the first base plate, and the first and second base plates are moved by the second cam mechanism. It is preferable to form so as to swing. In other words, with such a configuration, a complicated operation such as a combination of the first, second, and third reciprocating motions can be performed without using a pneumatic actuator. Work environment and noise pollution can be avoided.

It comprises a back and forth moving means 104 for moving back and forth.
The back-and-forth moving means 104 is composed of a slide unit 105 and a feed screw unit 106.
Reference numeral 5 denotes a rail member 1 for projecting the ridge 108 of the slide base 107.
09 is slidably fitted in the rail groove of 09,
The feed screw unit 106 has a structure in which a male screw member 111 is screwed into a female screw member 110 connected to the slide base 107, and the male screw member 111 is rotated by a motor 112 for forward and backward movement.

The back-and-forth movement of the bobbin shaft 102 and the motor 103 is intended to be made by controlling the motor 112, winding of the winding position P _C and the interlayer tape and barrier tape to perform the winding of the coil material C The coil bobbin B can be selectively positioned at the taping position _PT for performing the traverse movement, that is, the width corresponding to the width of the winding, for the winding operation. The coil bobbin B is capable of causing the coil bobbin B to perform the forward / backward movement in steps.

The guide mechanism 200 is for regulating the feeding point of the coil material C wound around the coil bobbin B for winding on a fixed line.
Point restricting means 202 having a frame box 1
It protrudes from. In other words, the coil material C is regulated by the guide slit 201 and maintains a constant feeding point, and the coil bobbin B performs the above-described traverse movement with respect to the regulated coil material C, so that the winding has a predetermined width. Will be done. However, such a guide mechanism need not always be provided in the coil processing apparatus itself, and may be provided on the coil material bobbin apparatus side.

The assembly 300 for an interlayer tape is shown in FIG.
As shown in FIG. 6, a base plate 303 is attached to a frame body 302 attached to the frame box 1 via a swing support 301 so as to be able to move back and forth, and a tape supply mechanism 304 and a tape cutting means are attached to the base plate 303. 3
05 is assembled. The frame body 302 is formed by connecting a pair of upper and lower rail rods 306 and 306 at both ends thereof by connecting members 307 and 308 so as to be parallel to each other, and incorporating a support base member 309 at an intermediate portion thereof. And the support base member 3
A support shaft (not shown) of the swing support body 301 is connected to 09, and the swing support member 301 can swing about the support portion as an arrow X in FIG. This swing is caused by the frame 3
Up and down solenoid 31 connected to the front end of the valve 02
This is performed by vertical driving of 0. That is, one end of the rod portion 311 of the solenoid 310 is connected to the frame box 1, and when the solenoid is energized, the main body 312 of the solenoid 310 rises, and accordingly, the front portion of the frame body 302 tilts upward. And, on the other hand,
When the power supply is stopped, it returns to the original state.

The base plate 303 is moved back and forth by a back and forth movement mechanism as shown in detail in FIG.
The longitudinal movement mechanism includes a driving pinion gear 314 that is rotationally driven by a longitudinal movement motor 313 (FIG. 6) attached to the support base member 309, and a pinion gear 314 supported by a slide bearing provided on the support base member 309.
The main rack rod 315 meshed with the main rack rod 315 and the rail rods 306, 306 are supported via a pair of upper and lower slide bearings, while the transmission member 316 has the main rack rod 315 inserted through the slide bearings.
The transmission member 3 is engaged with the main rack rod 315.
16 is supported by a transmission member 316 via a transmission pinion gear 317 provided in the
One end of the auxiliary rack rod 318 is engaged with the transmission pinion gear 317 in a state of facing the main rack rod 315, and the transmission member 316 is abutted at one end to attach the auxiliary rack rod 318 to the left in the drawing, that is, to the front. It is made up of a spring 319 that is urged and stretched.

Such a forward / backward movement mechanism operates as follows. That is, when the pinion gear 314 rotates clockwise in the drawing, the main rack rod 315 moves forward. Accordingly, a force to move the auxiliary rack rod 318 backward is exerted via the pinion gear 317, but the movement is prevented by the tension force of the spring 319. That is, the rotation of the pinion gear 317 is prevented. As a result, the pinion gear 317 transmits the forward movement of the main rack rod 315 to the transmission member 316, and thus the transmission member 316
Then, the base plate 303 integrated with the above moves forward.

When the base plate 303 advances, the transmission member 316 is moved.
Contact screw 3 for adjusting the forward position provided at the upper end of the
When the pinion gear 314 is further rotated in this state, the auxiliary rack rod 318 moves backward against the tension of the spring 319. The function by which the auxiliary rack rod 318 is retracted will be described later.

On the other hand, when the pinion gear 314 is driven to rotate counterclockwise, the base plate 303 retreats.
As the main rack rod 315 retreats, the distal end 18 moves forward until the end stopper 321 contacts the transmission portion 316. When the advancing of the auxiliary rack rod 318 is stopped by the contact of the end stopper 321, the pinion gear 3
The rotation of the main rack rod 315 is transmitted to the base plate 303 via the transmission member 316 by the pinion gear 317 in the rotation stopped state, and the rotation of the base plate 3 is stopped.
03 will be retreated.

The supply mechanism 304 includes the reel holding unit 3
23, feeding guide unit 324, and pressing table 325
Consists of The interlayer tape T fed from the tape reel R of the holding unit 323 is supplied to the two guide rolls 326 and 327 of the feeding guide unit 324.
The leading end of the tape on the pressing base 325 is pressed against the pressing base 325 by the pressing roller 329 at the front end of the pressing bar 328. .

In this state, the pressing table 325 is positioned below the coil bobbin by moving forward as described above (the state shown in FIG. 4), and then the frame body 302 is caused to swing upward as described above. The leading end of the tape on the pressing base 325 is pressed, and the leading end of the tape is set on the coil bobbin.

After setting the tape in this manner, the coil bobbin is rotated next to wind the tape. Before that, the reel holding unit 323 makes the following adjustment. First, the structure of the reel holding unit 323 will be described. The reel holding unit 323 includes a swinging body 331 that is swingably attached to the base plate 303 via a swinging shaft 330 as shown by an arrow Y in FIG.
2 through a reel holder 333. The reel holder 333 is provided with the spring 3
34, the outer periphery of the tape reel R fitted on the holding shaft 335 is always pressed against the guide roller 336 at the upper end of the rocking body 330, so that the tape reel R swings integrally with the rocking body. Has been.

The reel holding unit 323 is pulled by the adhesive force of the tape T to the tape reel R at the time of setting the leading end of the tape, and is in a state shown by a solid line in FIG. 4, but prior to the winding of the tape. The rocking body 3 remains in a state where the leading end of the tape is forcibly fixed by being pressed against the coil bobbin by the pressing table 325.
The tape reel R is retracted by forcibly swinging the tape reel 31 into the state shown by the imaginary line, and the tape T is forcibly peeled off from the tape reel R for a length necessary for the subsequent winding. As a result, there is no resistance for removing the tape from the tape reel, and stable winding can be always performed.

The above-mentioned strong swing for this purpose is performed by the backward movement of the auxiliary rack rod 318 described above. That is,
The auxiliary rack rod 318 has a follower protrusion 337 projecting therefrom. The follower protrusion 337 tilts the rocking body 331 rearward as the auxiliary rack rod 318 retreats. The auxiliary rack rod 318, which has been retracted necessary for this, is moved to its end stopper 32 as described above.
1 is once advanced to a state where it abuts on the transmission member 316, and the forcible swing of the swing body 331 is released.
This is to prepare for the retreat operation of the base plate 303 after the winding is completed.

When the winding of the tape is completed, the base plate 30
3 is temporarily retracted to the cutting position and stopped, where the tape T is cut by the tape cutting means 305. That is,
The tape cutting means 305 includes a cutting solenoid 338 and a cutting blade 33 moved up and down by the vertical solenoid 338.
The tape is cut by raising the cutting blade 339 at the cutting position. More specifically,
The tape T is cut by causing the frame body 302 to swing upward with the cutting blade 339 raised to the cutting position. If the tape is cut by swinging the frame body 302 in this manner, the tape T can be prevented from floating above the pressing table 325 at the time of this cutting, so that the transition to the next cycle can be made more stable. . When the cutting of the tape is completed, the base plate 303 retreats again and returns to the standby position, and one cycle is completed.

The barrier tape assembly 400 comprises a supply mechanism 2 and a setting mechanism 3 as shown in FIGS. 8 and 9, and as shown in FIGS. first reciprocating a in the vertical direction for between positions P ₁ and gripping position location P ₂ at the upper end
₁ performs the reference position P ₁ performs second reciprocating A ₂ in the lateral direction starting from the third reciprocating in the horizontal direction for between the other supply mechanism 2 and the position P ₄ entrainment with the gripping position P ₃ by performing the dynamic a ₃ second reciprocating simultaneously with the setting mechanism, gripping the end of the tape by setting mechanism 3 (first reciprocating) → settings by setting mechanism 3 to the coil bobbin 5 of the tape tip (second A cycle of (return) → winding of the tape T by the coil bobbin 5 (third reciprocation) is repeated to perform taping.

The respective structures will be described below. The supply mechanism 2 includes a reel holding unit 10, a feeding unit 11, and a tape leading end adjusting unit 12 arranged in this order from the top. Each unit is attached to the surface of the second base plate 13.

The reel holding means 10 includes a tape reel 14
The tape reel 14 is held in a vertically movable state by a holding member 16 which can be attached to and detached from a support bracket (not shown) projecting from the surface of the second base plate 13. It has become. Holding member 16
Can be used interchangeably according to the type of tape. In this example, two tape reels can be held so that two tape reels can be simultaneously held for taping the barrier tape as described later. I have.

The feeding means 11 is for feeding the tape T fed from the tape reel 14 so that the tape T is not loosened, and each of the two idle protruding from the surface of the second base plate 13 is provided. Rolls 17, 17 and one tension roll 18, which is located between the idle rolls 17, 17 and provides tension to the tape T, are configured to rotate in one direction.

The tape tip adjusting means 12 is for adjusting the tip of the tape for gripping as described later, and includes a temporary fixing means 19 for temporarily fixing the tape and a tape cutting means 20 for cutting the tape. It is specially designed to stably tape thin and difficult-to-handle barrier tapes.

One of them is a device applied to the temporary fixing means 19 to enable simultaneous processing of two tapes required in the case of a barrier tape, and the other is a tape cutting means 20. The guide body 21 is provided on the
Thus, the regulation of the side edges of the tape at the time of finishing the winding of the tape onto the coil bobbin can be performed.

More specifically, as shown in FIG. 10, the temporary fixing means 19 includes a mounting bracket 2 projecting from the second base plate 13.
A pair of temporary fixing bases 24 attached to the base 2 via its long holes 23 so as to be adjustable in position; and a pair of pressing bodies 25 for performing temporary bonding by pressing the adhesive surface of the tape against the attaching surface 24f of each temporary fixing base 24. Formed. Then, the upper part of each pressing body 25 is pivotally supported by a support shaft 26 projecting from the temporary fixing stand 24 to the extending mounting part as shown by the arrow α, while the lower part of each pressing body 25 is connected. The pressing members 25 are connected by a rod 27, and each pressing body 25 can be simultaneously rocked by a pressing solenoid 28 (FIG. 8) via the connecting rod 27. Can always be processed at the same timing. Although the operating force of the pressing solenoid 28 is transmitted to the connecting rod 27 through the pressing rod 29, the moving rod 29 and the pressing rod 29 are pressed in order to efficiently arrange the components in a narrow portion. Solenoid 2
8 is connected by a connection string 30.

The tape cutting means 20 has the guide member 21 as described above.
As shown in FIG. 5, side edge guide surfaces 31 for regulating one side edge of the tape T are formed on both left and right sides, and the cut tape T is warped and peeled off as indicated by the arrow β. The tape receiving surface 32 for preventing the side edge guide surface 3
1 is formed so as to be orthogonal to the side edge guide surface 31, and the cutting blade 3 is attached to the lower surface of the mounting plate 34 so that the upper surface is lower than the lower surface of the cutting blade 33.
3 is attached.

As described above, such a guide body 21 functions at the time of winding finishing, and its meaning will be described in detail below. That is, the tape cutting means 20
Is normally retracted to the standby position (the state shown in FIG. 8), and when the predetermined amount of tape has been wound, the cutting solenoid 35 (FIG. 8) advances to cut the tape. The height position of the tape cutting must be higher than the maximum rotation locus of the flange portion 5f when the coil bobbin 5 is rotated. The length of the unbonded portion becomes considerably long.

However, in the case of the barrier tape, there is also a very narrow one such as 1.5 m / m in width.
The long unbonded portion is likely to be slipped off during final winding, but if it is slipped out and wound, it will greatly hinder taping of windings and interlayer tapes that will be repeated thereafter. . In other words, the guide body 21 regulates such an unbonded portion so as not to be displaced when the guide body 21 is rolled up. By using such a guide body 21, a thin and difficult-to-handle barrier is used. It is the first time that accurate and stable taping of tape is possible.

The tape tip adjusting means 12 is attached to the second base plate 13 via the intermediate plate 36, and the bolt holes of the intermediate plate 36 are elongated to form The mounting height can be adjusted. This adjustment is performed to adjust the height position of the cutting blade 33 to coil bobbins of various sizes.

The setting mechanism 3 includes a tape holding means 3
7 is attached to a frame block 39, and a pressing roller 38 is attached to a bracket plate 38b connected to the first base plate 41. The frame block 39 is attached to a tip end of a slide shaft 40, and the slide shaft 40 Is held by two holding blocks 42 (FIG. 9) protruding from the back surface of the first base plate 41 so as to be able to move up and down for the first reciprocating movement.

Each of the tape gripping means 37 has a gripping piece 43 at the distal end thereof. The tape gripping means 37 is rotated around the pin supporting portion so that the gripping surfaces of the gripping pieces can be brought into and out of contact with each other. A pair of gripping arms 44, 44 and one end of which is pin-connected to the base end of the gripping arm 44, and a pair of output links 4 whose other ends are pin-connected.
The grip 46 formed by the grips 5 and 45 and the grip 4
6 is operated by applying an operating force of the gripping solenoid via an intermediate rod 48 to the pin connection portions of both output links 45, 45 as shown by arrow X. It is designed to work as a structure, whereby the operating force of the solenoid can be changed to a strong gripping force. The pressing spring 49 attached to one of the holding pieces 43 is for pressing the tape T to the coil bobbin 5 at the time of setting operation described later.

The pressing roller 38 is for applying a pressing force so that the tape can be easily adhered when the tape is wound by the coil bobbin 5. The pressing roller 38 is oscillated by an urging force in the direction of arrow γ by a spring. It is attached to the tip of the arm 50. The frame block 39 includes a slide shaft 40
The fixing frame member 51 fixed to the fixing frame member 52 and the holding frame member 52 for attaching the tape gripping means 37 are connected by the adjusting screw 53 and the rotation preventing member 54, and the holding frame member for the fixing frame member 51. The distance W (FIG. 13) between the members 52 can be adjusted. This adjustment is performed in accordance with the height position adjustment of the tape tip adjusting means 12, and is for adjusting the height positions of the gripping means 37 and the pressing roller 38 in accordance with the size of the coil bobbin.

[0044] Here, even if made such adjustment, the spacing when the setting mechanism 3 has reached the gripping position P ₂ at the upper end and the lower end of the upper and temporarily fixed table 24 of the holding frame 43 always constant As a result, the leading end of the tape T protruding below the temporary fixing stand 24 by a certain length can be surely grasped. The structure thereof will be described later.

The supply mechanism 2 and the setting mechanism 3 described above are provided to be supported by the second base plate 13 to the first base plate 41, respectively. The reciprocating motion is performed by a cam mechanism. It has been devised for this purpose. Hereinafter, this point will be described.

As shown in FIG. 14, the cam mechanism includes a first cam mechanism including a first cam 55 and a first cam follower 56, and a second cam mechanism including a second cam 57 and a second cam follower 58. Gears 59, 60 as seen in FIG.
And are formed in an interlocking state.

The first cam mechanism is for moving the slide shaft 40 up and down to perform the first reciprocating movement A ₁ of the setting mechanism 3, and the first cam follower 56 is attached to the slide shaft 40. The slide shaft 40 is moved up and down in accordance with the rotation of the first cam in the direction indicated by the arrow δ. That is, the first cam follower 56, the first cam 55 is in the lowermost position when taking the state indicated by the solid line in FIG, thereby the setting mechanism 3 is located at the reference position P ₁ of the lowermost. When the first cam 55 rotates from this state, the first cam follower 56 moves up along the ascending cam surface 55a in a locus indicated by a dashed line. This lifting force is provided by a spring (not shown) that urges the first cam follower 56 against the cam surface of the first cam 55. The first cam follower 56 is the intermediate stop cam surface 5
It reaches the 5b there provide a gripping position P ₂ to the setting mechanism 3 at the uppermost end. The tape tip is held by the tape holding means 37 during the slight stop time at the holding position. Then, when the first cam follower 56 engages with the descending cam surface 55c, the setting mechanism 3 starts descending. When the setting mechanism 3 moves from the descending cam surface 56c to the forward swinging stop cam surface 55d, the setting mechanism 3 moves to the reference position P _1. Return to. During this time, the second cam 57 also continues to rotate in conjunction with the first cam 55, but since the second cam follower 58 is along the up-and-down stop cam surface 57a, a swinging power is generated by the second cam 57. Absent.

[0048] Although so that this first stroke of the reciprocating A ₁ settings mechanism 3 taken in the varied according to the size of the coil bobbin 5, the height of the adjustment, the tape tip adjustment means 12 described above This is performed as a result of adjusting the distance between the fixing frame member 51 and the holding frame member 52 in the frame block 39 of the position adjustment and setting mechanism 3.

FIG. 13 schematically shows this relationship. FIG. 13A shows the case of the small-sized coil bobbin 5s, and FIG. 13B shows the case of the large-sized coil bobbin 5b. As described above, when the setting mechanism 3 is at the uppermost gripping position P1, the distance between the upper end of the gripper 43 and the lower end of the temporary fixing stand 24 is always constant. The upper surface of the member 52 abuts against a stopper projection 61 projecting downward from the intermediate plate 36 of the tape tip adjusting means 12,
This is because an ascending limit of the setting mechanism 3 is provided. On the other hand, the lower limit position of the setting mechanism 3 is given by the first cam 55 so that the fixing frame member 51 always comes to a fixed height position.

With such a structure, the height position of the tape tip adjusting means 12 and the distance between the fixing frame member 51 and the holding frame member 52 are adjusted in accordance with the size of the coil bobbin. ′, The vertical movement strokes S, S ′ of the setting mechanism 3 change in the relationship shown in the figure, and the strokes S, S ′ given thereby necessarily correspond to the sizes of the coil bobbins 5s, 5b. Will do.

As a result, as described above, the spring urging force for pressing the first cam follower 56 against the cam surface of the first cam 55 is used for the lifting force of the setting mechanism 3, while the stopper projection 61 is This makes it possible by using a structure in which the upper end of the setting mechanism 3 is regulated by the contact of the coil bobbin, thereby reducing the work required for changing the size of the coil bobbin.

Incidentally, due to such a structure, as can be seen from the comparison between (a) and (b), the upper limit position of the setting mechanism 3 is different depending on the size of the coil bobbin.
If this upper limit position is lower than the possible upper limit position regulated by the first cam 55, a partial play occurs on the cam surface of the first cam 55.

Next, the second cam mechanism will be described.
The cam mechanism swings the first and second base plates 41 and 13 to perform the second reciprocating movement A ₂ of the setting mechanism 3 and the third reciprocating movement A ₃ of the supply mechanism 2. A second cam follower 58 is connected to the first base plate 41, and the first and second both follow in rotation of the second cam 57 in the arrow μ direction in conjunction with the rotation of the first cam 55. Base plate 4
1 and 13 are rocked.

Specifically, the second cam 57 is provided with gears 59 and 6
The interlocking of the through 0 in which always works in synchronism with the first cam 55, in a state where the setting mechanism 3 is in the reference position P ₁ of the lower end, the second cam follower 58, the return swing cam surface 57d and the upper and lower It is located at the left end position by pressing against the boundary point with the stop cam surface 57a (the state shown by the solid line in FIG. 12), and accordingly the setting mechanism 3 and the supply mechanism 2
Are located at the left ends, which are the gripping positions P ₂ and P ₃ . When the second cam 57 rotates in response to the rotation of the first cam 55 from this state, the cam follower 58 is in contact with the up-and-down stopping cam surface 57a while the setting mechanism 3 is being raised, so that the swinging motion occurs. Although this does not occur, as described above, the cam follower 58 starts to hang on the setting swinging surface 57b at the same time when the gripping of the tape tip by the tape gripping means 37 is completed, and swinging to the left is started.

This swing is caused by the first and second base plates 41,
13 start at the same time, but the end positions of the second base plate 13 are different. When the second base plate 13 swings, the stopper receiver 62 provided thereon contacts the stopper 63 provided on the frame box 1. By contact (FIGS. 8 and 12), the first base plate 41 stops short of the swing end position. This is a winding position where the feeding mechanism 2 takes up, and is set so that the tape T comes into contact with the side surface of the coil bobbin for the winding of the tape by the coil bobbin 5.

On the other hand, the first base plate 41 is set so that the gripping portion of the tape gripping means 37 in the setting mechanism 3 swings to a position where it passes over the coil bobbin 5. The tape T is set by pressing the adhesive surface of the leading end against the coil bobbin 5 for adhesion and releasing the grip at the same time. In this state, the second cam follower 58 hangs from the setting oscillating surface 57b to the temporary stop cam surface 57c, causing a temporary stop of the oscillating operation, during which the first cam follower 56 of the first cam mechanism causes the first cam 55 By going over the escape cam surface 55e, the setting mechanism 3 escapes slightly downward so as not to hinder the winding of the tape. Then, the second cam follower 58 oscillates on the return swing surface 57d and returns to the start point.

During the swing by the second cam mechanism,
In the first cam mechanism, the first cam follower 56 is in contact with the swinging stop cam surfaces 55d and 55f, and the first cam follower 56 is lowered by the above-described escape and the recovery cam surface 55g for recovering the escape. No vertical power is generated except for returning.

Here, the swinging of the first and second base plates 41 and 13 due to the partial interlocking is given by the following structure. That is, both base plates 41, 1
3 have a common swing fulcrum, that is, are commonly held by one swing shaft 64. As described above, the first base plate 41 directly applies the oscillating power to the second cam follower 58, while the second base plate 13 always has a rightward oscillating potential. The urging force is applied as described above, and the urging force is received by the first base plate. Specifically, as shown in FIGS. 8 and 12, the first base plate 4
When the interlocking pin 65 protruding from the abutment 1 contacts the upper end of the engagement opening 66 formed in the second base plate 13, the urging force is received.

Therefore, when the first base plate 41 swings rightward, the second base plate 13 also swings rightward as the first base plate 41 swings rightward, and the second base plate 13 is brought into contact with the stopper receiver 62 against the stopper 63. Only it is possible to stop halfway. Further, the second base plate 13 is returned and oscillated against the urging force by being forced by the interlocking pin 65 of the first base plate 41 that performs the oscillated return.

An appropriate spring may be used to apply an urging force to the second base plate 13, but as in this example, the setting mechanism 3 and the supply mechanism 2 are inclined and the gripping positions P ₂ , P _3. So that the second base plate 1
A sufficient biasing force can be obtained with only the own weight of 3.

Next, the first and second base plates 41, 13
The relationship between the swing fulcrum and the rotation axis of the first cam will be described. As shown in FIG. 9, the rotation axis of the first cam 55 is common to the swing shafts 64 of both base plates so that the axes of the two cams coincide. That is, as shown in FIG. 5, the moving radius r of the swing and the locus t of the vertical movement intersect on the common axis. As a result, the tape can be rocked while the length of the tape gripped by the tape gripping means 37 is always kept constant, and the tape does not loosen during rocking, thereby improving the stability of taping. . Further, the respective stop cam surfaces 55b, 55d, 55f, 57a, 57c of the first and second cams 55, 57, respectively.
May be an arc centered on each axis of rotation, which facilitates the design.
