Abstract

PURPOSE:To improve the thread guard efficiency, by breaking a thread by means of the winding force of a rotary member and the suction force of a suction gum, and hooking a plurality of threads to a plurality of rotary members. CONSTITUTION:A thread catching port 210 of an air suction gun 201 is faced with a thread Yd through elongation of an air cylinder 620 and the rotation of a rotary actuator 630, so as to catch the thread Yd which is then cut between a bobbin 22d through ejection of pressurized working water. After threads Yc-Ya are caught and cut sequentially in similar manner, the suction gun 201 is lowered and the threads Ya-Yd are hooked respectively to a thread guide hook 521, thereafter it is moved in the direction of (-y) together with a thread guide rail 520 so as to the threads Ya-Yd in contact with new bobbins 22a-22d, then it is moved in the direction of (-x) thus hooking the threads sequentially. Consequently, the efficiency is improved when a plurality of threads are hooked respectively to a plurality of rotary members (bobbins).

Description

Detailed Description of the Invention (Industrial Field of Application) This invention uses a suction gun that suctions and captures yarns with pressurized liquid to transfer a plurality of yarns to a plurality of rotating bodies (for example, bobbins). Concerning methods for hanging.

(Prior art and its problems) In the manufacturing process of synthetic fibers, etc., it is necessary to wind the spun yarn around a rotating bobbin or the like. To carry out this winding, it is necessary to thread the rotating bobbin, and it is effective to use a suction gun (suction device for thread threading) that uses pressurized fluid to thread the thread.

Such suction guns include types that use pressurized gas (for example, Japanese Patent Publication No. 60-6271) and types that use pressurized liquid (for example, Japanese Utility Model Publication No. 61-2536).
No. 0) are known, and each has its own unique characteristics.

On the other hand, in order to increase the efficiency of yarn winding as described above, a plurality of bobbins are often attached to a single winder and yarn winding is performed in parallel. In particular, recently it has become common for a single winder to be equipped with a large number of bobbins. For this reason, there is a need to improve the efficiency of threading with a suction gun and switching from a full tube to an empty tube, but types that use pressurized gas have weak suction power, so threading and switching operations are necessary. There are limits to efficiency and success rate.

On the other hand, suction guns that use pressurized liquid have a large suction force, and this type of suction gun is seen as promising for improving the efficiency of thread hooking and thread switching operations.

However, even when threading a large number of bobbins using a pressurized liquid gun, conventionally, no special measures were taken to thread the thread, as in the case of a small number of bobbins attached to one winder. I threaded each bobbin. Therefore, as the number of bobbins increases, the threading work becomes a burden, and the efficiency of the entire thread winding process is also affected.

(Objective of the Invention) The present invention is intended to overcome the above-mentioned problems in the prior art, and by making full use of the characteristics of a suction gun using pressurized fluid, a plurality of threads can be passed through a plurality of rotating bodies. It is an object of the present invention to provide a threading method that can improve the efficiency of threading threads onto rotating bobbins, for example.

(Means for Achieving the Object) In order to achieve the above-mentioned object, in the present invention, a plurality of yarns supplied from the yarn supplying means are As a method for threading each thread onto a plurality of rotating bodies, the method includes: (1) sequentially capturing the plurality of threads with a single suction gun; and (2) threading the plurality of threads captured by the suction gun with the a second step of winding each of the threads around a plurality of rotating bodies; The present invention provides a method comprising a third step of cutting the plurality of threads using a pulling force and a suction force of the suction gun, and threading the plurality of threads on the plurality of rotating bodies, respectively.

Note that "threading" in this invention is a concept that also includes threading work associated with thread switching.

Therefore, in the following, the details of each of these parts will be divided into sections, and then the threading method using this threading device 200 will be explained.

B. Yarn Winding System First, the yarn winding system 100 will be explained. As described above, this yarn winding system 100 is equipped with a plurality of machines 30, and as shown in FIG. A plurality of ducts 32 are arranged on the lower surface. A molten polymer is applied to this spin block 31, and each duct 32 is supplied with a molten polymer from a base (not shown).
A plurality of threads Y (four threads Y-Yd in this example) are spun through each thread. Therefore, in this embodiment, the spin block 31, the duct 32, and the like form the yarn supply means.

The yarn Y thus spun is provided to a yarn winding device 500 via a Godet roller 33.

This yarn winding device 500 is configured by attaching a plurality of bobbins 22 (22a to 22d) to a winder 21, and the yarns Ya-Yd are rotated at high speed by the bobbins 2.
2a to 22d, respectively.

Therefore, in this embodiment, the bobbins 22a to 22
d corresponds to a "rotating body" for winding the yarn.

C8 piping FIG. 2 is a schematic plan view showing the spatial arrangement of the pressurized water supply piping 220 and the drainage piping 230 shown in FIG. 1.

In FIG. 2, in this embodiment, pressurized water supply piping 22
0 and the drainage pipe 230 are connected to the machine base 30 (30a, 30b,
) are provided separately for each. These pressurized water supply piping 220 and drainage piping 230 are fixedly arranged individually for each machine 30.

Among these pipes, the pressurized water supply pipe 220 is formed of a main pipe 221 and a branch pipe 222, as shown in FIGS. 1 and 2.

One end of the main pipe 221 is connected to a pressurized fluid supply position P (Pa, Pb) in FIG. 2, which is set near the end of the machine stand 30.

...), and its opening is the pressurized water intake port 2.
The number is 241. As will be described later, this pressurized fluid supply position P is a position where the threading device main body 300 is placed. However, in this embodiment, one threading device main body 300
The machine stand 30 that performs threading by moving between the machine stands 30
It is used by temporarily placing it at the pressurized fluid supply position P. Therefore, the threading device main body 300 is not always arranged at one of the pressurized fluid supply positions P.

In addition, the main pipe 221 is branched to both sides of the machine stand 30, and each branch is connected to the machine stand 30f7) (l!!@t (not shown).
It grew to a point where it was closed. Further, a branch pipe 222 is connected to this main pipe 221, one for each yarn winding device 500, and this branch tube 222 extends to the vicinity of each yarn winding device 500. A pressurized water outlet 224e is provided at the end of this branch pipe 222.

The drainage pipe 230 is also the same, and has a main pipe 231 and a branch pipe 23.
It is formed by 2. And these main 2
31 and the branch pipe 232 extend in the same direction as the main pipe 221 and the branch pipe 222 in the pressurized water supply piping 220, and the branch pipe 232 has a drainage intake port 2341, and the main pipe 231 has a drainage discharge port 234e. are provided for each.

The pressurized water inlet 2241 and the pressurized water outlet 224e are formed by detachable joints (so-called "one-touch couplers"), and near the openings there is a valve 2 shown in FIG.
25i and 225e are provided, respectively. The drain inlet 2341 and the drain outlet 234e are similarly formed of detachable joints, and valves 235i and 235e are provided near their openings, respectively. Various types of such detachable joints are known, but
In this embodiment, one without a valve is used.

By doing so, pressure losses in these joints can be reduced.

The configuration of the pipes 220 and 230 described above is also shown schematically in FIG. 3.

The installation heights of the pressurized water supply pipe 220 and the drainage pipe 23o can be arbitrarily selected. However, in this embodiment, as shown in FIG. 1, the height is set near the middle between the godet roller 33 and the yarn winding device 500.

Among the openings of each piping explained here, pressurized water intake 2
241 and the drainage outlet 234e are connected to the threading device main body 300, as shown in FIGS. 1 and 3. Furthermore, the pressurized water outlet 224e and the drainage intake port 2341 are connected to the suction gun 201. In this connected state, the suction gun 201 is supplied with water and drained of water while threading work is performed, which will be described later.

D. Thread l! ) Apparatus main body FIGS. 4 and 5 are respectively a front internal layout view and a left side view of the threading apparatus main body 300. Also, Figure 6 shows
3 is a diagram showing a waterway configuration and an electrical configuration in a threading device main body 300. FIG. The configuration of the threading device main body 300 will be described below with reference to these figures.

First, in FIGS. 4 and 5, this threading device main body 300 has a wagon-shaped outer shape, and is placed on a trolley 302 to which wheels 301 are attached. This wheel 3
01 has a shape that fits the rail 303, so that the threading device main body 300 is movable on the rail 303. This rail 303 is provided along a path connecting each of the pressurized fluid supply positions P in FIG.

The trolley 302 in FIGS. 4 and 5 includes a water storage device 310.
, a pressure device 320, a waste yarn processing device 350, and the like are provided. Among these, the water storage device 310 is
It is equipped with a water storage tank 311 fixed to the lower part of the tank. This water storage tank 311 is for storing the working water W to be given to the suction gun 201 from the threading device main body 300. This water tank 311 is provided with a float 312 and a water surface level meter 313 for detecting the water surface level.

Further, a defoaming tank 315 is provided above the water storage tank 311 via a pipe 314.

This defoaming tank 315 is for extinguishing foam when the working water W in the water storage tank 311 foams. That is, as will be described later, in this embodiment, in order to circulate and use the working water W, the oil applied to the yarn Y by an oil applicator (not shown) mixes into the working water W. When the number of circulations increases, the content ratio of the oil in the working water W increases, and a large amount of bubbles is generated in the water tank 311.

As a result, the operating efficiency of the threading device 200 decreases. For this reason, in this embodiment, the foam overflows into the defoaming tank 315 through the pipe 314 to bring the foam into contact with more of the atmosphere, thereby promoting the defoaming of the foam. Therefore, the upper part of the defoaming tank 315 is left open.

Next, the pressurizing device 320 will be explained. This pressurizing device 320 includes a low pressure pump 32 mounted on a trolley 302.
1 and a high pressure pump 322. These pumps 321 and 322 are rotationally driven by motors 323 and 324 shown in FIG. 6, respectively. Also, these motors 3
23.324 is rotated by power provided through switch 325.326.

Among these pumps 321,322, low pressure pump 32
1, water is stored Pa31 by the water supply hose 327 in FIG.
The working water W stored in this water tank 311 is pumped up and pressurized. Pressurized working water W
is sent to radiator 328. This radiator 32
A fan 330 rotated by a motor 329 is disposed at a position opposite to the fan 8 . This motor 329 is
Power is supplied through the same power supply path as the motor 323 described above (see FIG. 6). Therefore, while the low pressure pump 321 is being driven, the fan 330 will also be rotating.

Due to the action of the fan 330 and the radiator 328, the working water W after passing through the radiator 328 becomes appropriately cooled pressurized water. The reason why it is desirable to perform such cooling is related to the fact that the working water W is used in a circulating manner. That is, due to repeated friction with various parts of the circulation channel, the working water W becomes quite high in temperature, and eventually becomes so hot that the suction gun 201 cannot be held with bare hands. For this reason, it is desirable to cool the working water W by some method. Therefore, in this embodiment, the working water W is air-cooled using the fan 330 and the radiator 328.

The working water W after being cooled by the radiator 328 is
The water is sent to the high pressure pump 322 via the water supply hose 331 shown in FIG. A high-pressure hose 333 extending to the outside of the wagon body 370 via a pressure regulating valve 332 and a discharge hose 334 communicating with the water tank 311 are connected to the high-pressure pump 322 . The pressure regulating valve 332 is provided with a pressure regulating valve 335 that protrudes to the outside of the wagon body 370. Among these, the high pressure hose 333 is provided with a detachable joint 336 at its external open end.

Further, a valve 337 is attached near the open end. Furthermore, the discharge hose 334 is for returning water of the working water W sent from the low-pressure pump 321 to the water storage tank 311. On the other hand, the pressure regulating valve 332 adjusts the discharge pressure of the working water W from the high pressure hose 333 according to the operation amount of the pressure regulating valve 335, and when the discharge pressure of the high pressure pump 322 is excessive, the pressure of the pressurized water is adjusted. The part is connected to the water tank 311 by the branch hose 338.
It has the function of refluxing to

On the other hand, as shown in FIG. 6, a relay switch 339 with a timer is inserted between the motor 324 that drives the high-pressure pump 322 and the power switch 326. This relay switch 339 is operated by a float 312 provided inside the water tank 311. In other words, float 31
2, when it is detected that the water level of the water tank 311 is lower than a predetermined level and this state continues for a predetermined time or more, the relay switch 339 is activated and the motor 324 is stopped. Therefore, the working water W in the water storage tank 311
If the water level becomes low, the high pressure pump 3 will automatically turn on.
22 can be stopped and idle running can be prevented.

Next, the waste yarn processing device 350 shown in FIG. 4 placed on the cart 302 will be explained. This waste thread processing device 35
0 includes a dehydration tank 351 and a drainage tank 352 that are coaxially arranged. Of these, the waste water and waste thread S collected from the suction gun 201 flow into the dewatering tank 351 via the collection hose 353. A large number of small holes 354 are provided in the wall surface of this dehydration tank 351. Therefore, of the inflowing wastewater and waste threads S, only the wastewater flows down into the drain tank 352 through the small hole 354.

Further, this dehydration tank 351 is rotated at high speed in the α direction in the figure by a motor 355. The waste yarn S collected in the dehydration tank 351 is thereby centrifugally dehydrated. As shown in FIG. 6, this motor 355 is connected to a timer 356. Then, when the switch 357 is turned on, the timer 356 measures a predetermined period of time, and power is supplied to the motor 355 for that period. Therefore, motor 35
5 rotates the dehydration tank 351 only during this period.

Further, the recovery hose 353 (FIG. 4) is provided with a detachable joint 358 at its external open end. Further, a valve 359 is attached near the open end. Note that the drain tank 352 communicates with the water storage tank 311 through an outflow bowse 360.

On the other hand, the cart 302 has a waste yarn storage tank 3 having a lid 380.
81 and the handling par 382 are connected to the hinge 383,
384 respectively. For this reason,
As shown by arrows A and B, the waste thread storage tank 381 and the handling par 382 have their respective upper parts connected to the wagon body 3.
It is a foldable type that can protrude to the outside of 70.

E. Suction Gun FIG. 7 is a cutaway sectional view of the suction gun 201. In the figure, this suction gun 201 is constructed by attaching a water supply hose 203 and a drainage hose 204 to a metal suction gun body 202. Among these, the suction gun main body 202 has a supply pipe 20 for taking pressurized working water supplied from a water supply hose 203 into its interior.
It is equipped with 5. Further, this supply pipe 205 is provided with a valve 206 .

The supply pipe 205 communicates with a ring-shaped pressure water chamber 207 provided within the suction gun body 202. This pressure water chamber 207 is connected to a first injection nozzle 209 via a water pipe 208.
is connected to. This first injection nozzle 209 faces the outlet pipe 211 via a yarn capture port 210 formed by a predetermined gap. The outlet tube 211 is a hollow tube having a thread passage hole 212. And thread passage hole 212
A plurality of injection holes 213a are opened concentrically at predetermined positions. The plurality of injection holes 213a form a second injection nozzle 213, and their narrow ends are connected to the pressure water chamber 20.
It is connected to 7. However, the axial direction of each injection hole 213a has a predetermined inclination with respect to the axial direction of the yarn passage hole 212.

On the other hand, the water supply hose 203 includes a flexible hose body 214 attached to the supply pipe 205 and a detachable joint 215 attached to the end of the hose body 214. Further, a valve 216 is provided near the joint 215.

The drain hose 204 attached to the rear end of the outlet pipe 211 is similar, and has a flexible hose body 217, a detachable joint 218, and a valve 219. In addition,
In the case where the suction guns 201 are fixedly provided to each of the yarn winding devices 500 as in this embodiment, the valves 216 and 219 can be omitted.

When pressurized hydraulic water is supplied to the suction gun 201 having such a configuration, the pressurized hydraulic water is jetted from the first jet nozzle 209 toward the yarn passage hole 212 . For this reason,
When the suction gun main body 201 is moved manually or automatically and the yarn catching port 210 approaches the yarn Y, the yarn Y is moved to the yarn passing hole 2 by the jetting force of pressurized water.
12 and is captured by suction.

Then, the yarn Y that has proceeded through the yarn passage hole 212 together with the pressurized working water is further sprayed with pressurized working water from the second injection nozzle 213 . As a result, the yarn Y is further accelerated and discharged from the drain hose 204 together with the water. In this state, while suctioning the yarn Y at high speed, the suction gun main body 202 is moved to a desired location to thread the yarn Y. Since the suction force generated by the pressurized working water is quite large, after threading, the yarn Y is automatically cut by the tension from both the threading light and the pressurized working water.

Note that the yarn Y discharged from the drainage hose 204 along with the drainage becomes yarn waste.

F. Yarn winding device Next, the configuration of the yarn winding device 500 will be explained.

This yarn winding device 500 is formed by combining a mechanism used during the original yarn winding process and a yarn winding guide mechanism 510 used during yarn winding. These will be explained below with reference to FIG.

F-1. Mechanism for winding yarn As a mechanism for winding yarn, in addition to the winder 21 and bobbins 22a to 22d described above, the first and second
A yarn path regulating guide 50.5L and a traverse device 510 for uniform winding are provided. Of these, the yarn path regulation guides 50.51 are formed by attaching, for example, four snail guides 52.53 to arms 54.55 extending from the machine base 30, respectively. Among these, the arrangement interval of the snail guides 53 in the second thread path regulation guide 51 is determined according to the arrangement interval of the bobbin 22.

On the other hand, four sets of traverse devices 501 are provided corresponding to each yarn Ya-Yd. This traverse device 501 includes a fork-shaped (U-shaped) traverse guide 502 for guiding the yarn Y, and a traverse drive mechanism (not shown) that reciprocates this traverse guide 502 in the horizontal X direction in the figure. It is equipped with

F-2, Threading Guide Mechanism The threading guide mechanism 510 includes a threading guide rail 520 which is shaped like a cylinder with a notch extending horizontally below the arrangement of the bobbins 22a to 22d, and a cutout portion of this threading guide rail 520. The yarn guide hook 521 is provided with four yarn guide hooks 521 that partially protrude from the yarn guide hook 521.

FIG. 8 is a diagram showing the internal mechanism of this thread hooking guide mechanism 510. In FIG. 8, the yarn guide hook 521
(521a to 521dH7) One end of each is connected to four sets of air cylinders 522a to 5 arranged in the vertical direction.
22d, respectively. Air ports 523 and 524 are provided near both ends of each of these air cylinders 5228 to 522d, and by introducing air from the air port 523 on the left side in the figure, the yarn guide hook 521 is ) direction. Furthermore, when air is introduced from the other air inlet/outlet 524, the yarn guide hook 521 moves in the (-X) direction. Therefore, the thread guide hook 521 forms a movable rod of the linear air actuator.

The strokes of these four sets of air cylinders 522a to 522d are not the same, and therefore the movable ranges of the yarn guide hooks 521a to 522d are also different from each other. That is, as shown by the virtual line M, when each yarn guide hook 521a to 521d is moved to the left side in the figure, these yarn guide hooks 521a to 521d are moved to the left side in the figure.
The left ends of 521d are arranged at intervals of Δχ from each other. In addition, as shown by solid lines, each yarn guide hook 52
When the yarn guide hooks 1a to 521d are moved to the right side, the left ends of these yarn guide hooks 521a to 521d are arranged at intervals of L from each other. Furthermore, the movement range of the lowermost yarn guide hook 521a is Xa. however,
How to determine these distances Δx, l, and xa will be described later.

Four sets of air cylinders 522a having such a configuration
~522d is a moving table 526 by a holder 525.
Fixed on top. This moving table 526 is fixed to sliders 528 of two linear motion sliders 527,
It is movable in the illustrated y direction by a driving air cylinder 529. In Fig. 1, this y direction is
This corresponds to a direction toward or away from the bobbin 22.

G. Support Stand Next, the structure of the support stand 600 disposed near each yarn winding device 500 will be described with reference to FIG. 9A. This support stand 600 includes a rodless cylinder 610 erected on the floor surface 34. The movable part 611 of this rodless cylinder 610 is integrated with an air cylinder 620 extending in the X direction. Therefore, by driving the rodless cylinder 610, the air cylinder 620 moves up and down in two directions (vertical direction).

On the other hand, a rotary actuator 630 is fixed to the tip of the movable rod 623 of the air cylinder 620.

A suction gun 201 is attached to a rotor (not shown) of this rotary actuator 630. Therefore, by introducing air into the air inlet/outlet 621 or 622 of the air cylinder 620, the suction gun 201 moves horizontally in the X direction. In addition, the air inlet/outlet 631 or 63 of the rotary actuator 630
By introducing air into 2, suction gun 2
01 rotates in the θ direction.

)・1. Threading Method Next, a method of threading in the yarn winding system 100 using the threading device 200 having such a configuration will be described.

First, before performing the threading operation, the pressurized water supply pipe 220 and the drainage pipe 230 are connected to each suction gun 201 in advance. This is the pressurized water outlet 224e.
This is done by connecting the joints 215 and 218 of the suction gun 201 to the drainage intake port 2341 and the drainage intake port 2341, respectively. Once this connection is made, the pressurized water supply piping 222
Also, the drain pipe 230 and each suction gun 201 may be left connected. In addition, valves 225e and 2351 attached to the pressurized water outlet 224e and the drainage intake port 2341 are also kept open.

Next, when actually threading, the threading device main body 300
is moved on the rail 303, and the threading device main body 300 is placed at a pressurized fluid supply position Pd corresponding to the machine stand 30 (for example, the machine stand 30d in FIG. 2) on which threading is to be performed. For this movement, please use the handling par 3 shown in Figure 4.
Just like pulling down the 82, I pulled this handling par 382 manually.

Next, connect the joints 336, 358 in FIG. 4 to the machine 30d.
The pressurized water intake port 2241 and the wastewater discharge port 234e shown in FIG. By using removable joints as these joints, the above-mentioned connection and disconnection operations become extremely easy. FIG. 1 shows the state in which the connection is completed in this way.

After such connection has been made, the operator turns on switch 325, 326 in FIG. 6 and opens valves 337, 225i, 359, 235e in FIG. Furthermore, the yarn winding bag @ (for example, 500
Valve 2 of the suction gun 201 connected to a>
16,219°206 will also be opened. However, valve 206 is not shown in FIG.

By such an operation, pressurized working water (for example, pressurized working water of 60 K9/ci G or more) from the threading device main body 300 is supplied to the suction gun main body 202 via the pressurized water supply pipe 220. Suction gun body 202
The waste water and waste yarn are discharged to the threading device main body 300 via the drainage pipe 230.

After confirming that the injection state of the pressurized working water in the suction gun body 202 is stable, the operator carries out threading in the following order. However, in order to enable threading as described below, the lengths of the water supply hose 203 and drainage hose 204 of the suction gun 201 are set to the length of the pressurized water outlet 224e.
and the distance from the drainage intake port 2341 to the corresponding thread winding device 500 to some extent.

Next, the worker proceeds with the threading work according to the following steps.

(a) First, air is introduced from one air inlet/outlet 621 of the air cylinder 620 in FIG. 9A, and the suction gun 201 is moved horizontally in the (-X) direction. Then, the drive of the air cylinder 620 is stopped at a position where the yarn capture port 210 of the suction gun 201 is adjacent to the yarn Y.

Next, the air inlet/outlet 6 of the low reactor unitaro 30

, to face. Then, the yarn Yd passes through the yarn capture port 210.
from the inside of the suction gun 201.

At this time, the running yarn Y is cut by the jet energy of the pressurized working water from the first jet nozzle 2O9 installed at the tip of the suction gun main body 202. Then, this thread Y is guided to the injection position of the second injection nozzle 213 along with the jet stream.

Then, the ejection force of the second ejection nozzle 213 is applied to the yarn Y, and as a result, the yarn Y is suctioned and captured by the suction gun 201. Therefore, after this:
The yarn Y supplied from the mouthpiece 40 is sucked toward the suction gun 201 side. The yarn Yd sucked in this way becomes waste yarn.

After capturing one yarn Y in this manner, air is introduced into the other air inlet/outlet 632 of the rotary actuator 630, the suction gun 201 is reversely rotated in the θ direction, and the yarn capturing port 210 is directed upward. Then, air is introduced into the air inlet/outlet 621 of the air cylinder 620 again.

As a result, the suction gun 201 further (
-X) direction, and the yarn catching port 210 is moved horizontally to the yarn Y direction.

This horizontal movement is stopped at a position adjacent to . The subsequent capturing and cutting operations are similar to those described above.

By sequentially repeating the above procedure for the yarns Yd-Ya, these yarns Yd-Y8 are attached to the suction gun 20.
1, it will be in a state of being attracted and captured sequentially. The reason why a single suction gun 201 can suck and capture a plurality of yarns Y - Yd is because the suction gun 201 is of a type that uses pressurized water (generally pressurized liquid). be. In other words, since the suction force of a suction gun using pressurized gas is weak, it is difficult to suction and capture such a plurality of threads. In particular, recently, the yarn winding speed has increased to 3000 m/min or more, and 4500 to 500 m/min.
A yarn winding speed of 000T11/min has been put into practical use. When threading or switching threads on such high-speed threads, using a suction gun that uses pressurized air has a low success rate, making it unsuitable for practical use. be.

Note that until the above acquisition is completed, the traverse device 501
is kept on, the yarn Y before being captured is performing reciprocating motion in the X direction. Therefore, in order to reliably capture the yarn Y, it is desirable to perform the capturing operation directly below the second yarn path regulating guide 53. This is because the amplitude of the reciprocating motion of the yarn Y is small in this vicinity.

(b) After suctioning and capturing the four yarns Y8 to Y in this manner, the rodless cylinder 610 is driven to lower the suction gun 201 downward (FIG. 9B). At this time, air is introduced from the air inlet/outlet 524 to all of the air cylinders 522a to 522d in FIG.
The position is shown in . Then, in the state shown in FIG. 9B, the yarn guide hooks 521a to 521d and the yarn Y8
~Yd are arranged in a positional relationship alternately. In other words, the interval ΔX shown in FIG.
Yarn Y8 at the position of the thread hooking guide rail 520 in Figure B
The arrangement interval is set to approximately Yd. Note that the winder 21 is stopped before or after this operation,
Replace boggon 22 with a new empty bobbin.

Next, the four yarns Y to Yd captured by the suction gun 201 are attached to the yarn guide hooks 521a to 522d.
Thread on. When threading this thread, first,
8 to Yd can be engaged with the J-shaped portions 530 (FIG. 8) at the tips of the yarn guide hooks 521a to 521d.
y between 8~Yd and yarn guide hooks 521a~521d
It is necessary to adjust the position in the direction. If it is positioned so that it can be engaged from the beginning, the suction gun 201
This is because the threads Y to Y interfere with the thread guide hooks 521a to 521d when the threads are lowered downward.

Such position adjustment can be done, for example, by using the yarn guide hook 5.
This can be done by lowering the suction gun 201 while moving the yarn guide hooks 521a to 521d in the (-y) direction, and then moving the yarn guide hooks 521a to 521d in the (+y) direction.

Next, air is introduced into the air inlets and outlets 523 of the air cylinders 5228 to 522d in FIG. 8 to move the yarn guide hooks 521a to 521d to the right in the figure. At that time, the J-shaped portions 530 of the yarn guide hooks 521a to 521d
are engaged with the yarns Y - Y, respectively, and these yarns Y
-Y, is pulled to the right in the figure. Finally, as shown in FIG. 9C, the yarn guide hook 521
a to 521d, the mutual spacing of yarns Y to Y is 8th.
It is equal to the distance IIL in the figure.

In this state, the driving air cylinder 529 in FIG.
As shown by the imaginary line in FIG.
-y) direction.

Therefore, the yarns Y8 to Y engaged with the yarn guide hooks 521a to 521d are attached to new bobbins 22a to 22d.
come into contact with.

These bobbins 22a to 22d are made of paper, for example, and have a notch 60 as a thread hooking portion at a predetermined position on the surface thereof.
a to 60d are provided. Then, in the state shown by the imaginary lines in FIG. 9C, the threads Ya-Yd are arranged to correspond to the positions of the cuts 608 to 60d in the X direction, respectively.

That is, the spacing shown in FIG. 8 is set to be equal to the arrangement spacing of the bobbins 22a to 22d shown in FIG. 9C. Moreover, as the moving distance×8 in FIG. 8, a distance is selected so that the yarn Ya fits into the cut 60a after the movement.

On the other hand, before moving the yarn guide hooks 521a to 521d in the direction (d) in FIG. 9C, the traverse device 5
01 is stopped. However, in this stopped state, the X direction position of the four sets of traverse guides 502 is at the notch 60a.
It is made to match the X direction position of ~60d.

Therefore, as shown in FIG. 9C, the yarn guide hook 521a
~Move 521d in the (-X) direction and move the yarn Y8~
Yd is inserted between the two fingers of each traverse guide 502, and bites into the notches 60a to 60d of the rotating bobbins 22a to 22d, so that these bobbins 22a
~22d, respectively.

(c) In this way, the yarn Y ~ Yd is the bobbin 22a ~
22d respectively, the bobbins 228-22d
starts winding yarns Ya-Yd, respectively.

However, in the yarn Y - Yd, the cut 60a = 606
The part that digs into becomes the tail.

At the moment when such winding is started, the suction gun 201 is applying suction force to the yarn Y-Yd. Therefore, the yarn Y-Y.

Among them, bobbins 22a to 22d and suction gun 201
The winding force of the bobbins 22a to 22, d and the suction force of the suction gun 201 act on the portion between them, so that the yarn Y is instantaneously broken under tension. As a result, the yarns Ya to Yd are automatically cut between the portions wound around the bobbins 22a to 22d and the portions sucked by the suction gun 201. In this way, multiple threads Y ~
Y.

The reason why it is possible to cut both at the same time is because it uses a Zakujon gun that uses pressurized liquid.

Through the above steps, threading to the bobbins 22a to 22d is completed, and the suction gun 201 and threading guide mechanism 510 are returned to their initial states. Note that air is supplied to each of the air cylinders, rotary actuators, and the like from an air compressor or the like via compressed air supply piping (not shown).

Further, each air cylinder is driven based on the operation of a control switch, a control valve, etc. (not shown). These operating sequences may be executed manually and sequentially.
It may also be realized using a control circuit such as a microcomputer.

When the yarn winding for one yarn winding device 500a is completed in this way, the operator
Close the valves 206, 216, and 218 provided in the.

The thread winding device (for example, the thread winding device 500b in FIG. 1) that should perform the thread threading operation next after this thread threading operation is the same as the thread winding device 500a that previously performed the thread threading operation. Machine stand 3
At the time belonging to 0d, the threading device main body 300 remains placed at the same pressurized fluid supply position @Pd. Then, the valves 216, 219, and 206 of the suction gun 201 corresponding to the yarn winding device 500b are opened to supply pressurized water to the suction gun 201. After that, the work procedure is the same as that described above. Note that each of these valves can also be formed using a solenoid valve that is automatically operated by an electric signal. In this case, the valves are opened and closed by electrical signals. Also, suction gun 201
The side valves 216.219.206 are optional;
The waterway opening/closing operation may be performed only by the valve 2351 on the machine stand 30 side. Furthermore, as in this embodiment, the suction gun 201 has valves 216, 219, and 206.
Even if there are , these may be kept in the "listening" state at all times.

When the threading work for one machine 30 (for example, machine 30d in FIG. 2) is completed, the threading operation for another machine (for example, machine 30
When carrying out threading work regarding b), the work procedure is as follows. That is, first, the valve 337 in FIG.
, 359.225 i.

235e is closed and fittings 336, 358 are disconnected from the fittings forming pressurized water inlet 2241 and waste water outlet 234e, respectively.

After that, manually attach the thread hooking device main body 300 to the rail 30.
3 to the pressurized fluid supply position Pb for the machine stand 30b in FIG.

Then, the thread hooking device main body 300 is moved to the pressurized fluid supply position p.
b temporarily, and repeat the same operation as above.

On the other hand, while the threading device 200 is operating as described above, waste water is being discharged from the drain pipe 220 to the dewatering tank 351. Further, during threading, waste water and thread waste S are discharged into the dewatering tank 351. During normal operation, the switch 357 shown in FIG. 6 is always turned on. As a result, the dewatering tank 351 continues to rotate, and the waste yarn S is centrifugally dehydrated. Of course, it is also possible to rotate the dewatering unit 1351 intermittently, but in that case, waste threads will be unevenly distributed in the dehydrating tank 351, and the starting current at the start of rotation will become large. Therefore, in such a method, a load is placed on the motor 355. On the other hand, if it is always on as described above, this problem does not occur. The water obtained by dehydration returns to the water storage tank 311.

dehydration? When the amount of waste yarn S accumulated in the ff351 increases, the worker pulls down the waste yarn storage tank 381 shown in FIG. 4 and manually transfers the waste yarn S in the dewatering tank 351 into this waste yarn storage tank 382. This is performed every time waste thread S accumulates in the dewatering tank 351 to a certain extent. Therefore, the burden of transporting the waste yarn S in the dewatering tank 351 to a waste yarn collection place (not shown) each time is reduced.

By repeating the above steps, yarn winding system 1
The threading work in 00 is performed one after another. Since the plurality of bobbins 22a to 22d are threaded simultaneously, threading efficiency is significantly improved. In addition, in this embodiment, since the pipes 220 and 230 are provided, the threading device main body 3
00 only needs to be moved between the main body arrangement positions P set for each machine stand 30, and the yarn winding device 50
There is no need to move between zeros.

(2) Data example The thread hooks in the above-described embodiments show examples of experimental data for work. However, in order to confirm the effectiveness under harsher conditions than the system shown in Figure 1, we installed eight threads in one winder and attempted to thread these eight threads. . Other conditions are as follows.

(a) Yarn...75 denier, 36 filament polyester terephthalate (b) Motor 324 for high pressure pump 322...11KW
H motor (c) Pressurized water pressure to suction gun 201...17
0 to 9/Cr4G At this time, the yarn suction tension of the suction gun 201 is 12 g per yarn, and the yarn suction speed is 600 g.
0 m/min is obtained. It has been confirmed that eight threads can be reliably threaded using a single suction gun 201 when threading is carried out in accordance with the above-described procedure. The threads are also cut automatically, and no cutting equipment such as a cutter is required.

For comparison, an attempt was made to thread the yarn in the same manner as above using a suction gun using pressurized air. However, even if a 60KWH motor was used as an air compressor motor, it was impossible to capture and thread a plurality of threads as described above.

Further, even in the case of a single thread, the thread cannot be cut automatically, and a tool such as a cutter must be used.

Therefore, it can be seen that the above embodiment is a technique that effectively utilizes the characteristics of a suction gun using pressurized liquid.

J. Modifications Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments described in I.2 above, and for example, the following modifications are also possible.

■ In the above embodiment, the yarn guide hook 521 was moved to the bobbin 22 side when threading, and the yarn Y was wound onto the bobbin 22. However, in the state shown by the solid line in FIG. The positional relationship between the suction gun 201 and the yarn guide hook 521 and the bobbin 22 may be set so that they are in contact with the bobbin 22. In this case, by simply moving the yarn guide hook 521 in the (+X) direction, each yarn Ya
~Yd is adapted to the position of each notch, so that the yarn Y
~Y, winding is automatically started. In this case, a mechanism for moving the yarn guide hook 521 in the y direction is not necessary. In addition, the yarn guide hook 521 and the bobbin 2
The positional relationship with the thread Y is the same as in Example F.
A movable arm or the like may be provided for pressing the bobbin 22 against the bobbin 22.

Furthermore, threading may be performed by manually moving the suction gun 201 without using the thread guide hook 521 or the like.

(2) In the above embodiment, the case was explained in which the pipes 220.
The present invention can also be applied to a case where the pressurized liquid is directly supplied from the threading device main body 300 without arranging the threading device 230. Also, piping 2
20, 230, the threading device main body 3
00 may not be made movable, but may be fixed and arranged for each machine.

(Effects of the Invention) As explained above, in this invention, by taking advantage of the characteristics of a suction gun that uses pressurized liquid, it is possible to thread multiple rotating bodies at once with a single suction gun. Therefore, there is an effect that efficiency when threading a plurality of threads onto a plurality of rotating bodies is significantly improved.
