Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing system for yarns, and in particular to a processing system suitable for producing fancy yarns.

As a system for creating frost patterns, random color patterns, etc. in textiles, knits, etc., for example, in a loom,
B) A system in which multiple types of yarns with different colors are prepared for the weft yarns, and the weft yarns are selected randomly or regularly to perform the weft insertion operation. There are systems that create random patterns by printing and dyeing after weaving.

However, in case (a), it is necessary to perform the weft selection operation every cycle or multiple cycles of weft insertion operation, which becomes an obstacle to increasing the speed of the loom, and in the case of a loom with a large weaving width, it is necessary to perform the weft selection operation every cycle or multiple cycles of the weft insertion operation. It is impossible to make the colors different in small pitches. In other words, if the weaving width is 2 m, 2 m of weft threads are of the same color, and in the middle of the weaving width, for example, 5 m.
It is impossible to change the color every 0 bites.

Furthermore, since the above-mentioned system uses print dyeing, only low-quality fabrics can be obtained, and it is extremely troublesome and time-consuming to express complex and random color tones.

From this point of view, the yarn wound into a yarn supply package is unwound and dyed in different colors at small intervals, for example, at intervals of several tens of meters to several meters, and then wound again and used as a feeder for looms and knitting machines. If used as yarn, the above problems would be solved, but partially dyeing such a single yarn was extremely complicated and required large-scale dyeing equipment.

The present invention has been made to solve the various problems mentioned above. That is, in the present invention, a plurality of types of yarns are prepared for one winding package, a yarn splicing device and a yarn type selection device are arranged between the package and the yarn feeder, and the yarn on the package side and the yarn on the yarn feeder side are arranged. Yarns were selected as appropriate according to the commands of the control device, and splicing was performed so that the yarns in the wound package had yarns of different colors or yarns with different characteristics at intervals of several tens of d to several i. It is something.

Embodiments of the system of the present invention will be described below with reference to the drawings.

Fig. 1 shows the system configuration of the present invention, including a yarn feeding section (1), a yarn selection section (2), a yarn splicing section (3), and a winding section (4).
), and a control section (5) that controls the operation of each of the above sections.

That is, in the yarn feeding section (1), for example, a plurality of types of yarn feeding packages (2) to 0 of different colors are appropriately arranged without interfering with each other. The above yarn feeding packages (A) to (F) have already been rewound in a winder and yarn defects such as slabs have been removed, and then dyed in the dyeing process. It can be used in

Further, the yarn selection section (2) reserves the yarn ends pulled out from each yarn supply package, and selects and positions a specific yarn end to a yarn running position according to a command from the control section (5), for example. , the rotation plate (6) holding each yarn end is rotated around the shaft (7), and the yarn end (YA) is moved to the running position (Y).
) to (YF).

Furthermore, a yarn splicing section (3) disposed following the yarn selection section (2) forcibly cuts the yarn that is connected between the yarn supply package and the winding package (8) and has stopped. A device that connects a desired type of yarn end to a yarn end connected to the winding package (8), and includes a yarn cutting device, a yarn splicing device, and a guide device for guiding the yarn end to a fixed position of the yarn splicing device.

Note that as the yarn splicing device (9), devices such as Fisherman's knotter and Liver's knotter, which form knots, are not suitable; No. 58-74472) is applicable. That is,
In this system, the thread being wound is forcibly cut every ten or so α to several numbers by the control device, resulting in an extremely large number of knots, and the thickness of knots such as fisherman knots and weaver knots is 2 to 3 times that of single threads. The thread tying device also serves as
When the rolled up package is used in the knitting process, the above knots are likely to get caught on knitting needles, warp threads, etc., resulting in thread breakage.
Furthermore, even if yarn breakage does not occur, knots protrude to the surface of the produced woven or knitted fabrics, resulting in extremely low commercial value.

Furthermore, a normal winding device is applied to the winding section (4). That is, the threads are spliced onto a package (8) which is rotated by a traversing drum (10), and threads of different colors are wound at regular pitches or at random pitches.

The control device (5) that controls the selection of yarn type, winding length, etc.
), a relay sequence, a microcomputer, etc. are used.

A portion of the yarn produced by such a system is
As shown in the figure. That is, since one yarn (Yl) is spliced by a pneumatic yarn splicing device, the seam is almost indistinguishable from a single yarn, and is in the form of a single thread, and the yarn portion (A)
is the red thread of package (A), the following thread part (B) is the blue thread of package (B), the thread part (C) is the yellow thread of package (C), and the thread part (1)) is the package ( D)

(c) Thread splicing part The thread splicing part is the liver knot that the applicant previously applied for.
A pneumatic yarn splicing device that splices yarn into a single thread without forming a knot such as a fisherman knot (for example, Japanese Patent Laid-Open No. 58-7
No. 4472) shall apply. That is, Figures 7 to 9
In the figure, an embodiment of the yarn splicing device is shown.

The yarn splicing device (3) basically includes a yarn splicing member (37), a yarn presser (38), an untwisting nozzle (39) (40), a yarn pulling lever (48), and a new thread trimmer @ (41) ( 42)
, a yarn clamp device (43) (44), a first suction pipe (45) that suction-holds the yarn end on the package side, a second suction pipe (46) that suction-holds the yarn end on the yarn feeding side, Furthermore, it is composed of a cutter (47) that cuts the yarn connected between the yarn feeding side and the package side, a rotating arm (29) that guides the yarn end on the yarn feeding side mentioned above to the yarn splicing member (37), etc. .

That is, the yarn end (YP) on the package side is held by the suction pipe (45) while being held by the clamping device (43).
The free yarn end is clamped at a fixed distance from the tip of the yarn end by the cutting device (45), and is sucked into the untwisting nozzle (39) to untwist the yarn end. On the other hand, the yarn end (YU) on the yarn feeding side is connected to the suction pipe (46).
The thread is clamped by a clamping device (44) in a state where it is suctioned and held, and is cut by a cutting device (42).The free yarn end is sucked into an untwisting nozzle (40) and subjected to an untwisting action. Further, due to the rotational movement of the thread shifting lever (48), the thread ends in the untwisting nozzles (39) and (40) are pulled out.
The yarn ends are overlapped in the yarn splicing hole (49) of the yarn splicing member (37) and spliced together by the action of compressed fluid.

The rotating arm (29) that pulls out and guides the yarn end (YU) on the yarn feeding side is rotatably supported by the frame (5o), and the yarn gripper (30) at the tip grips the yarn end as shown in FIG. The yarn gripper rotates greatly in the direction of the arrow (51), and a roller provided on a part of the movable piece (32) of the yarn gripper engages with the cam plate (52) shown in FIG. 7, and the movable piece opens and grips. Release the yarn feeding side yarn end that had been attached to the suction pipe (4
6) Suction inward. The above-mentioned rotating arms (two) have an abbreviated shape and are provided with gears (54) on a shaft (53) integral with the arm.
) and the sector gear (55) are in zero alignment, the sector gear (55) is driven by a program cam driven by a command from the control unit, that is, a knotting command, the arm (29) rotates, and the thread on the selection device side is After the end is pulled out from the yarn supply, it moves 11 degrees above the yarn splicing member (37) and engages with the cam plate at a position where it has turned approximately 18σ.

The end of the yarn connected to the package is cut by a cutting device (
47), and at the same time, it is sucked and held by a nearby first suction pipe (45).

In this way, each yarn end (YP) (YU) is positioned at the solid line and broken line positions in FIG. 7, and yarn splicing preparations are carried out.
Thread splicing is performed by the above-mentioned operation. (56
) to (60) are thread guides.

B) Control Unit Next, the control unit that controls the operations of each of the above devices will be explained. FIG. 10 shows a block diagram of the control device. That is, the control unit (5) includes a program controller (61) and an oscillator (62), and the program controller (61) includes a high-speed counter (64) that counts pulse signals (63) from the oscillator (62). ,
A counter control unit (6) that controls the counting time of the counter.
5) Furthermore, a block (66) for selecting the winding time, a block (67) for selecting the yarn type, and a rotation plate of the yarn selection section according to the yarn type selection signal based on the counter set value at the time when the counter (64) stops. Output section (68
), a knotting command section (69), etc.

The output signals from the control section select and operate the yarn type selection solenoids (SOA) to (SOE), and the knotting circuit contact (7o) operates to start knotting.

The operation timing of solenoids (SOA) to (SOE) is determined by the thread cutting device (which cuts the thread when winding is stopped).
The timing is determined by the program cam of 47) and the switch (72), and after cutting the light, the rotation plate (
6) Once returns to the origin, the solenoid operates.

Note that one cycle of knotting is set by a program cam and a switch (71), and the knotting ends after one cycle, that is, one revolution of the camshaft.

In addition, a switch (73) is provided in the cradle arm of the package, for example, to temporarily stop counting in the counter control section in the event that the thread breaks due to some trouble during winding with the wine goo. The package is provided in a cradle portion that is lifted up to stop the rotation of the package. Stop switch (74
) is a switch to be used when winding has finished on -day or when winding is to be temporarily stopped for some reason.
4) etc. is input to the counter control unit (65), the counting of the counter (64) is temporarily stopped, the pulses counted up to the time of stopping are temporarily stored, and when the start switch (75) is turned on, The counter (64) is again controlled so that it continues counting after the count at the time of stopping.

(E) Winding unit As shown in FIGS. 1 and 3, the winding unit (4) has a package (8) whose surface is driven by, for example, a traversing drum (10).
) is rolled up as a cone or cheese package. In addition, (76) in FIG. 3 is a yarn guide, and (77) is a tension device.

In addition, when winding is stopped by a command from the control section, it is desirable that a brake shoe or the like for forcibly stopping the rotation of the package or the drum (10) is controlled by a fluid cylinder by a program cam.

Different yarns (
It is assumed that yarns YA) to (YF) are prepared and gripped by each yarn end gripping piece (15) of the selection device (2).

In this case, the high speed counter (64) in Figure 10 is 000.
It is possible to count up to 999, and the output can be set in multiple stages. For example, if 32 points can be used, 32 types of yarn can be used. Now, for example, set the color printer settings as shown in Table 1.

Immediately, the counter (64
) shifts and stops at a certain set time, and the winding time of the thread being wound, the type of thread for the next knotting, and the shift time of the next counter are selected based on the set value of the counter at that time. For example, in Table 1, if the set value when the counter is stopped is between ooo and 055, the value is +) L, %.
When (HDMOO) is activated, the yarn type is A, the winding time is 1.5 seconds, and the next counter shift time is 0.
Set it to 1 second. Similarly, when the counter stops, the value is 0.
If it is between 56 and 111, the yarn type B1 winding time is set to 20 seconds, and the next counter shift time is set to 0.2 seconds.

Therefore, in FIG. 11, the counter shifts at the same time as the winding start switch is turned on (78), and stops after a certain period of time. At this time, the counter value is, for example, 8.
5, the relay (HDM■) is activated, stops after winding (W■) for 2.0 seconds, yarn cutting and knotting are started, and with timing, the solenoid for yarn B (SOB) is activated. The solenoid rod (S
TB) protrudes above the substrate. That is, in FIG.
The timing at which the solenoid rod (STB) protrudes is determined by the rotation of the rotating plate (6) in the two-point chain direction after the thread is cut, and the stopper (STB) position is reached, the 4th rib plate (6) is positioned to stop, and the thread (B) is The gripping piece (15) gripping the yarn end reaches the knotting and running position. Thereafter, the rotating arm (29) shown in FIG. 7 is operated to guide the yarn end of a predetermined type on the yarn feeding side to the yarn splicing member and splice it with the yarn end on the package side.

Further, the next counter shift time (t■), that is, 0.2 seconds, is selected by the relay (HDMO). After knotting is completed, winding of the B type yarn is started (79) and the counter stops after 0.2 seconds. If the value of the counter at this time is 025, the relay (HDMQ) is activated and the relay (HDMQ) is activated.
Various signals corresponding to (O) are selected, the B type yarn on the package side and the A type yarn on the yarn supply side are spliced, the winding is restarted, and the winding time of the A type yarn is set by a relay (HDM2 ).

For example, in Fig. 11, the actual winding time of type B yarn is the shift time (0.2 seconds) by the counter relay (HDMO) and the winding time (0.2 seconds) by the relay (HDMO).
However, since the shift time of the counter is extremely short, it is almost equal to the winding time (W) determined by the relay (HDMO).

In this way, the value when the counter stops takes a random value, and therefore the yarn type and winding time also become a random combination, and random winding and knotting are performed, for example, as shown in Figure 2. Fancy yarn is wound in random combinations of colors and lengths. In order to make the process even more random, the selected yarn type, winding time, and counter shift time can also be selected using a random number table. However, if the product is manufactured as a knitted or woven fabric, the color tone will be similar. There is a possibility that it will come. Furthermore, for example, if you want to manufacture woven or knitted fabrics based on red, you can do so by setting a large amount of red in the variety selection.

That is, in Table 1, relays (HDMOO) to (HDMO
For 2), the yarn type is red, relay (HDMO3) ~ (H
If DMO5) is set to blue, yellow, and white, the probability that the red yarn will be selected during footing will be duck, and for other varieties it will be h, and the probability that the red yarn will be selected will be duck. It is highly likely that Of course, it varies depending on the winding time, but if the winding time is the same for each group, the above probability holds true. As described above, the present invention includes a yarn feeding section having a plurality of types of yarn feeding for one winding package, a yarn splicing device disposed between the yarn feeding section and the winding section, and a yarn splicing device arranged between the yarn feeding section and the winding section. A yarn type selection device for selecting the package side yarn end and the yarn feeding side yarn end to be spliced is provided between the section and the yarn splicing device, and a control device for controlling the yarn type selection and winding time. As a result, it is possible to manufacture fancy yarns in which yarns of different colors or properties are present at random intervals in one yarn, and all that is required is to prepare different types of yarns in advance and wind them. It can be used as fancy yarn for weaving and knitting immediately after the weaving process, and the process can be simplified.
