[0005]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, have reached the present invention. That is, the present invention provides a liquid ejection device for injecting or flowing liquid from an arbitrary direction to a running yarn, a deformed or eccentric rotating roller attached to a rotating shaft connected to a motor at one end, and a coaxial with the rotating roller. A rotation detection pin attached to the detection pin, and a rotation detection member installed on the rotation trajectory of the detection pin, wherein the motor receives a predetermined electric signal and moves the rotation axis in any direction with the rotation detection member as a boundary.

The gist is an intermittent liquid applying device.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic view showing one embodiment of an apparatus for applying intermittent liquid to a yarn of the present invention, and FIG.
FIG. 5 is an explanatory view showing movements of a rotating roller and a yarn of the device of FIG.

In FIGS. 1 and 2, a liquid is injected from a needle 1 to form a liquid flow L, sent to a water receiving port 2, filtered by a filter (not shown), collected, and recycled. The yarn Y is made of a rotating roller 3 attached to a rotating shaft 5.
, And reciprocates in the direction of arrow a by its rotation. On the way, the liquid intersects with the liquid flow L, the liquid is intermittently applied, and the process proceeds to the next step.

FIGS. 1 and 2 show a case in which the rotary roller 3 is of an elliptical shape. However, if the rotary roller 3 can reciprocate the yarn Y over a sufficient distance, the rotary shaft may be changed. An eccentric type having an eccentricity, a polygonal type, or a type having a plurality of protrusions on the peripheral surface may be used. Since the eccentric type may generate vibration when rotated, an elliptical or polygonal type is preferably used.

A motor 4 is directly connected to one end of the rotating shaft 5. The motor 4 receives a predetermined electric signal from a rotation control device (not shown) and rotates at a speed corresponding to the signal. As a result, the rotating shaft 5 is rotated, and the yarn Y traveling in contact with the rotating roller 3 is reciprocated to cross the liquid flow L. The other end of the rotating shaft 5 extends in the longitudinal direction of a processing machine or the like and is supported by a bearing (not shown). Although the example of FIG. 1 shows a case where a motor is directly connected to one end of the rotating shaft 5, when the rotating shaft 5 is long, the motor 4 is directly connected to both ends to rotate the rotating shaft 5. It may be.

A rotation detecting pin 6 is attached to the rotating shaft 5 (in FIG. 1, two places separated by 180 degrees in the circumferential direction), and when the rotation detecting pin 6 passes through the rotation detecting
Stops for a predetermined time. Next, upon receiving a predetermined electric signal from the rotation control device, the rotation shaft 5 is rotated. That is, the rotation speed of the rotation roller 3 can be stopped at an arbitrary speed after stopping the rotation detection member 6 for an arbitrary time each time the rotation detection pin 6 passes through the rotation detection member 7, and the stop time is set to zero. This makes it possible to change the rotation speed while rotating continuously. The rotation detection member 7 may be of a contact type or a non-contact type as long as it can detect the rotation detection pin 6.

In the present invention, it is preferable that the liquid ejecting apparatus can arbitrarily change the amount of liquid ejected or discharged. Further, the shape of the needle 1 constituting the liquid ejection device is not limited to one having one ejection port,
A device having a plurality of discharge ports may be used. In this case, it is also possible to perform different processing in the yarn length direction by using a plurality of types of liquids and successively ejecting the liquids in a discontinuous manner.

The length of the portion where the liquid adheres to the yarn Y is affected by the running speed of the yarn Y, but the diameter of the liquid flow L and the speed of the reciprocating movement of the yarn Y, ie, the diameter of the needle 1 and the like. It can be adjusted by the rotation speed of the rotating roller 3. The length of the non-adhered portion of the liquid can be adjusted similarly to the adhering portion. However, when the length of the non-adhered portion is to be increased, the rotation roller 3 stops when the yarn Y and the liquid flow L do not intersect. In this case, the position of the rotation detection pin 6 may be set. Conversely, when it is desired to lengthen the adhered portion, the position of the rotation detection pin 6 may be adjusted so that the rotation roller 3 stops when the yarn Y and the liquid flow L intersect.

As described above, when liquid is applied to the yarn Y using the apparatus of the present invention, the yarn Y travels in contact with the peripheral surface of the rotating roller 3 and repeats a reciprocating motion due to the rotation. The liquid intersects with the liquid flow L, and the liquid is intermittently applied. However, in order to stabilize the running of the yarn, it is preferable to provide a groove on the peripheral surface of the rotating roller 3 and to run through the groove.

[0014]

In the apparatus of the present invention, the running yarn is moved to cross the yarn and the liquid flow, so that the contact time between the yarn and the liquid flow per time can be reduced. In addition, even if the running speed of the yarn is increased, the length of the liquid adhering portion can be shortened. In addition, by stopping the rotating roller at an arbitrary position for an arbitrary time, the length of the liquid adhering portion and the liquid non-adhering portion can be freely adjusted.
Moreover, there is an advantage that the cost can be reduced by collecting and circulating the liquid without the need for a complicated device, and there is no need to increase the installation space. It is a thing.

[0015]

Next, the present invention will be described in detail with reference to examples.

Examples 1 to 3 The apparatus of the present invention shown in FIGS. 1 and 2 was provided between the first feed roller 8 and the first heater 9 of the false twisting machine shown in FIG. A total of four rotation detection pins were mounted on the rotation shaft, one on each side in the short axis and long axis directions of the rotation roller, and a rotation detection member was installed so that the rotation roller stopped at both ends of the reciprocation of the yarn. . The position of the needle was adjusted so that the yarn and the liquid flow intersect at an intermediate point of the reciprocation of the yarn. In FIG. 2, 10 is a second feed roller, 11 is a second heater, 12 is a false twist disk, 13 is a delivery roller, 1
4 is a winder, 15 is a pump, and 16 is a pump.

The processing was performed by using a polyester multifilament of 230 denier / 48 filaments as a supply yarn, using water as a liquid to be applied, and applying a liquid under a false twisting condition shown in Table 1 and a water applying condition shown in Table 2; Twisting was performed continuously.

[0019]

[Table 2]

Table 4 shows the properties of the obtained processed yarn. The lengths of the water-adhered portion and the non-water-adhered portion were determined by dyeing the obtained processed yarn by a conventional method, and calculating the lengths of the light-colored portion and the dark-colored portion by 10 respectively.
The length of the light-colored portion was determined as the length of the water-adhered portion, and the length of the dark-colored portion was determined as the length of the non-water-adhered portion.

Comparative Examples 1 to 3 As shown in FIG. 3 (b), the liquid comprising the liquid tank 17 and the roller 18 disclosed in Japanese Utility Model Publication No. 61-35592 is located at the same position as the liquid applying device in the first embodiment. Processing was performed under the same conditions as in Example 1 except that the application device was installed. Table 3 shows the water application conditions at this time, and Table 4 shows the characteristics of the obtained processed yarn.
Shown in

[0022]

[Table 3]

[0023]

[Table 4]

As is evident from Table 4, the processed yarns obtained in Examples 1 to 3 had a short length of the water-adhering portion, a large difference in shade and shade, and also exhibited a good operating condition of the apparatus.

On the other hand, in Comparative Examples 1 and 3, although the contact time with the roller was set to 0.04 seconds, which is the shortest time that the apparatus can operate, the length of the water-attached portion was long, and Was also small. In Comparative Example 2 in which the contact time with the roller was 0.02 seconds, the operation of the liquid application device became unstable, and a processed yarn could not be obtained.

[0026]

The use of the apparatus for applying intermittent liquid to yarn of the present invention makes it possible to extremely shorten the contact time between the running yarn and the liquid. Therefore, even if the running speed of the yarn is high, the liquid It is possible to reduce the length of the attachment portion.
