2. Description of the Related Art As shown in FIG. 4, an automatic winder 1 is connected to a spinning machine 5 such as a ring spinning machine via a yarn supplying conveyor 31 and an empty yarn returning conveyor 30, and is produced by the spinning machine 5. The pipe thread thus formed is directly supplied to an automatic winder in the next step and rewound to remove a thread defect in the thread and rewound into a package having a predetermined shape and a predetermined shape. Dozens to tens of yarns are usually used to obtain one package. This automatic winder 1 has a large number of winding units U arranged in parallel, and the device configuration of one winding unit U will be described with reference to FIG.

In FIG. 5, the winding unit U has a machine base 55 whose position is fixed by a support pipe 52 and a duct 53, and is drawn out from the yarn 10 which is positioned and supplied to a predetermined position of the winding unit U. The yarn Y is a balloon breaker 56,
After passing through the cutter 60, the tensor 57, the slab catcher 58, etc., the traverse drum 63 winds the winding package 64. 65 is a yarn splicing device,
66 is a suction mouth that guides the yarn on the package side to the yarn joining device 65, and 67 is the yarn joining device 65 on the yarn supplying bobbin side.
It is a relay pipe that guides you to. By the way, the supply of the tubing 10 to the predetermined position of the winding unit U is performed by inserting the tubing 10 into each independent tray 12. The distribution supply path 16 is arranged along the back surface of the winding unit U, and the return path 14 is arranged along the front surface.
By the rotation of the disc-shaped feeder 69, new pipe thread 10 is taken in from the distribution supply path 16 and the empty paper tube 11 is discharged to the return path 14. The disk-shaped feeder 69 is provided with two standby positions in addition to the winding position A, so that two spare tube yarns 10 can be placed.

The yarn Y unwound from the tube yarn 10 passes through a balloon breaker 56 and a tensor 57, and is checked by a slab catcher 58 as a defect detection head for a yarn defect, and is rotated by a traverse drum 63. A package 64.
To be wound up. During winding, slab catcher 5
The variation in the thickness of the yarn passing through 8 is output as an electric signal, and by comparison with the reference value, it is judged that the yarn defect has passed when the allowable range is exceeded, and the controller (not shown) immediately notifies the cutter 60. A command signal is output and the cutter 6
0 operates and thread cutting is performed. When the yarn is cut, the yarn traveling signal from the slab catcher 58 is turned off, the yarn break is detected, and the yarn joining cycle is started. That is, a stop command is issued from a controller (not shown) to the drive motor of the traverse drum 63, and the rotation of the traverse drum 63 is stopped. At the same time, the suction pipe 66 and the relay pipe 67 are actuated to carry the yarn to the yarn joining device 65 for yarn joining.

Further, the winding unit U has two spare yarn threads 10 at the standby positions B1 and B2 in addition to the yarn yarn 10 at the winding position A.
have. When the tube yarn 10 at the winding position A becomes empty, the yarn traveling signal of the slab catcher 58 is interrupted. In this state, it is indistinguishable from thread breakage by the tenser 57 or the like. Therefore, a yarn clearer (not shown) is used to check the presence of a lower thread, and a bobbin change is performed with a signal that there is no lower thread. The empty paper tube 11 at the winding position A is discharged, and the tube yarn 10 at the standby position B1 is carried in instead. Then, the yarn end Y1 is blown up, and the yarn joining device 65 is connected by the relay pipe 67.
Be carried to. At the same time, the upper yarn of the winding package 64 is also carried to the yarn splicing device 65 by the suction mouth 66, and the yarn splicing is performed. Then, new winding of the yarn 10 is started. In this way, one winding package 64 is usually formed by winding several tens to several tens of yarns 10.

[0006]

By the way, in the spinning process using a spinning machine, it is preferable to manage the relative humidity at 60% or less and reduce the water content of the yarn to carry out the twisting process. However, it is said that in the rewinding process using an automatic winder, it is preferable to control the relative humidity to 70% or more and set the moisture content of the winding package to a predetermined value. However, in the system in which the spinning machine and the automatic winder are directly connected as shown in Fig. 4, the spinning process and the rewinding process are continuous, and it is difficult to classify them and manage them at different humidities. There is a problem that it is not possible to secure a residence time for changing the water content of the yarn before the rewinding process. Therefore, it is conceivable to install a steam setter in front of the automatic winder, but the steam setter is a large-scale facility, the layout is complicated, and the facility cost is high.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to adjust the moisture content of the rewind package by adding a simple device. To provide an automatic winder.

[0008]

SUMMARY OF THE INVENTION An automatic winder of the present invention that achieves the above object comprises a winding unit having a large number of rows.
An automatic winder provided with a tube yarn supply path leading to the winding unit, wherein a water applicator for directly supplying water to the tube thread supply path is provided.

[0009]

The water supply device provided in the yarn supplying path leading to the winding unit gives water directly to the yarn, and the applied water adheres to the surface of the yarn, and is further passed through the guide and the tensor in the rewinding process. The surface moisture is applied to the package threads substantially uniformly.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a device layout view of an automatic winder of the present invention, and FIG. 2 is a perspective view of a spray-type water applying device.

In FIG. 1, the automatic winder 1 is provided with a winding unit U and a circulation path of the tray 12 which is a supply path 13 → a distribution supply path 16 → a winding unit U → a return path 14 → a supply path 13. . The insertion device 4 for receiving the yarn 10 from the yarn supply conveyor 31 is provided at the inlet of the supply passage 13, and the outlet device 2 and the water content, which is a main part of the present invention, are provided along the flow of the supply passage 13. An application device 6 is provided. Further, the return path 14 is provided with a sorting device 3, and the empty yarn from the sorting device 3 is returned to the empty yarn returning conveyor 30.
Returned to. In addition, 15 is the return line 1 for the yarn thread of the spout
It is a bypass route to return to 4.

The inserting device 4 is for inserting the tube yarn conveyed from the spinning machine 5 through the tube yarn supply conveyor 31 into the tray 12. The spouting device 2 has a rotary disk 20 for sequentially feeding the yarn 10 and passes a yarn end blow-off device 21 and a yarn end suction device 22 into the yarn, as shown in FIG. The end Y1 is hung in the tube thread 10. At the time of this lead-out, for example, the yarn end Y1
When the yarn is wound around the yarn layer, the yarn end Y1 cannot be blown off from the yarn layer, which may result in a misfeed. Therefore, a photoelectric sensor 23 for confirming the presence or absence of the spout is provided, and the tubing 10 that has missed the spout is introduced into the bypass passage 15 by the switching device 24. The bypass path 15 merges with the return path 14, passes through the sorting device 3 and the insertion device 4, and enters the tapping device 2 again. Then, another wording is performed.

The water supply device 6 is provided in the supply path 13 after the insertion device 4, but it is preferably provided downstream of the above-mentioned dispensing device 2. This is because if the yarn is squeezed out after directly applying water to the tube yarn 10, the yarn end may be attached by the moisture, which may adversely affect the squeezing. As shown in FIG. 2, in the moisture applying device 6, two spray pipes 35 and 36 are arranged so as to sandwich the yarn 10, and a tray 37 is provided at a predetermined position of a supply path 13 by a stopper 37 which can freely move back and forth. And the roller 38 which is pressed against the tray 12 and rotates to rotate the yarn 10. Spray tube 3
A large number of nozzles 39 are opened in the axial directions of the nozzles 5, 36, and water is sprayed from the nozzles 39 and sprayed directly onto the yarn 10. Therefore, the thread 1
The surface of No. 0 becomes wet and is transported to the winding unit. The amount of water sprayed can be adjusted by the number of nozzles 39 and the number of rotations of the yarn 10. Also spray tubes 35,3
Instead of No. 6, it is also possible to use a conveyer that inverts and conveys the tube yarn up and down so that the tube yarn passes through the water tank to add water.

The sorting device 3 of FIG. 1 includes a whisker sensor 25 for detecting the presence or absence of a yarn layer, a take-out conveyor 26, 27 having a lower side common to the upper side and a brush sensor 28 for detecting the presence or absence of residual yarn. have. The yarn yarn whose yarn layer is detected by the whisker sensor 25 is a miss-delivered yarn yarn or a semi-lens yarn, and passes through the extraction conveyors 26 and 27.
When the brush sensor 28 detects the residual thread, the tubular thread with residual thread extracted by the extraction conveyor 26 is sent to the residual thread removing device 29, and the empty tube thread from which the residual thread is removed joins the empty tube thread return conveyor 30. To do. A normal empty yarn without any residual yarn is extracted by the extracting conveyor 27 and conveyed to the spinning machine 5 by the empty yarn returning conveyor 30.

Next, the operation of the above-mentioned automatic winder will be described. The yarn 10 from the spinning machine 5 is the yarn supply conveyor 3
1 and is taken into the supply path 13 via the insertion device 4 of the automatic winder 1. Then, the yarn end is squeezed out by the squeezing device 2, and water is sprayed on the tubing 10 after the squeezing by the moisture applying device 6, so that the surface becomes wet. Then, the wet yarn 10 enters the distribution supply path 16 and is successively taken into the winding unit U where the yarn is insufficient. In each winding unit U, as described with reference to FIG. 5, one winding package 64 is wound from a large number of tube yarns 10 while removing yarn defects. At this time, the moisture on the surface of the tube yarn 10 adheres to the tensor 57 (not shown) of the winding unit U, and the moisture of the guides and the tensor spreads over the entire yarn indirectly, so that the moisture of the package is substantially evenly distributed over the entire yarn. Is given. In addition, since the rewinding of the tube yarn 10 is performed in an atmosphere with a large amount of water, there is an effect that the cotton wool is less likely to be scattered.

At this time, the photoelectric type shown in FIG. 3 is used for the slab catcher 58 of FIG. The slab catcher 58 detects a yarn defect such as a slab based on the thickness of the yarn. The slab catcher 58 optically detects the yarn diameter and the light receiver 3.
3 and 3. That is, a yarn defect such as a slab can be detected by measuring the potential difference between the output ends a and b of the light receiver 33. This slab catcher 58
The signal from is subjected to averaging processing in a signal processing unit (not shown) and compared with a reference value determined by the yarn count and the like by a comparator (not shown) to detect yarn defects such as slabs. Since the capacitance type generally used measures the capacitance which is approximately proportional to the yarn cross-sectional area, it is said that the diameter is large when the capacitance is large and the diameter is small when the capacitance is small. However, the measurement becomes impossible when the yarn is wet and does not become charged, but the photoelectric tube monitors the shadow of the yarn, so that measurement is possible even when the yarn is wet.

When the tube yarn 10 thus wet is rewound,
The thread becomes tight, and the warp (twisting into a loop) and sluffing (looseness in which a large number of threads are wound at once) are reduced. Therefore, fluctuations in unwinding tension due to chattering and sluffing are reduced,
The winding package is wound with uniform tension to reduce the number of loose winding points, and the unwinding property of the winding package is improved.

Furthermore, by providing substantially uniform water content to the entire yarn, the number of fluffs is reduced and the yarn strength is increased. As a specific experimental example, the fiber assembly is 48N
ec, a spun yarn having a fiber of 1.5 den is wound, and a tube yarn from a spinning machine is directly supplied to the winding unit (dry) and a case where water is supplied by spraying and supplied to the winding unit ( Wet) and the properties of the yarn after rewinding were compared. In the case of dry, the fluff (total length per 1m) is 4.20m, while
In the case of wet, it was 4.06 m. Since the fluff near 4 m is inevitably generated, the fluff reduction of 0.14 m is large. When dry, the average strength is 256g.
When it is wet, the average strength is 270 g (minimum strength 225 g), which is (minimum strength 205 g).

[0019]

The automatic winder of the present invention is provided with a water supply device for directly supplying water to the yarn supplying path leading to the winding unit, and the given water adheres to the surface of the yarn, Moisture on the surface of the yarn is applied to the entire yarn of the package almost uniformly through the guides and tensors in the rewinding process. It can be obtained with a simple equipment configuration that is attached. In addition, since the rewinding is performed in a water-rich atmosphere, there is an additional effect that less dust is scattered.
