Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thread hooking device for setting the thread on a regular running path connecting each machine element.

Due to the increase in the size of heaters associated with faster false-twisting processing, the entire false-twisting machine is becoming extremely large, and the operation of threading the yarn is becoming increasingly complex and difficult. In particular, since the heater is long, some type of operating tool is required to thread the thread through the entire length of the heater, and the quality of the operating tool greatly influences the operability of threading.

The present invention relates to an improvement of the above-mentioned operating tool, that is, a thread hooking device, and the main objectives of the present invention are ease and reliability of operation, and ensuring an ideal thread running path.

The present invention utilizes a false twisting machine in which the yarn pulled out from the yarn feeding bobbin is placed in an upright heater, the yarn is bent above the heater, and then wound into a package via a false twisting device. A guide rail is installed between the upper part of the heater and the false twisting device, and a slider that slides along the guide rail is provided, and the slider engages with the yarn. A feature is that a thread guide member is provided to guide the wire to the upper side of the heater.

The above-mentioned false twisting devices include a nip-type false twisting device that performs false twisting by nipping yarn between two endless belts that run at zero angles to each other; Refers to a friction type false twisting device etc. that performs false twisting, and a yarn cooling device may be disposed between the twisting outlet and the false twisting device, and a yarn cooling device may be installed between the false twisting device and the package for winding the yarn. Between (
A separate secondary heater may be provided here. It is preferable to install a balloon control plate between the heater outlet and the false twisting device to stabilize the running of the yarn, and it is convenient to use the guide rail integrally or in combination with this balloon control plate. , the guide rail is constructed so as to be inclined downward as much as possible from the upper part of the heater. The slider has a guide member, such as a roller, that engages with the thread, and when one thread is hooked, the slider engages with the thread below the guide rail, and then guides the thread along the guide rail (along which it reaches the upper part of the heater) by an appropriate means. The yarn is then turned and stopped or transferred to another retaining member to form the bend in the yarn described above.

Embodiments of the present invention will now be described based on the drawings.

FIG. 1 shows a false twisting machine employing the present invention, in which (1) is a creel stand that supports a yarn feeder (2).

A first feed roller (4) and a long primary heater (5) are provided on the negative side of the frame (3), and a false twisting device (7) and a second feed roller are provided on the other side across the working path (6). (8
), a secondary heater (9), an eighth feed roller (10), and a winder (11) are provided, respectively. Also, the upper part of frame (3) is the first balloon control play) (+3)
, thread cooling device (14)/second balloon control play)
(15) are provided respectively. The solid line and broken line (P3) in FIG. 1 indicate the yarn running path during normal yarn false twisting, and the yarn (T) consisting of the filament bundle pulled out from the yarn feeding package (2) is transferred to the first feed roller (4). A slider (16), which will be described later, passes through the heater (5).
The fibers are bent at an angle and descend diagonally along the first balloon control plate (13) and enter the thread cooling device (14). The yarn leaving the yarn cooling device (14) further passes through the second balloon control plate 05) and the false twisting device (7), and then passes through the guide bin (+7) fixed to the frame (3) again. It is bent and lowered in the vertical direction, passes through the second feed roller (8), the secondary heater (9) and the third feed roller (10), and is wound up by the winder (11) by one turn (+8). 0 On the normal running path (P3) of the above-mentioned yarn (■), the yarn (Y) runs between the first feed roller (4) and the slider (1).
The kite pin (1G) rises almost vertically between the slider (1G) and the guide bin, and runs diagonally downward between the slider (1G) and the guide pin
17) and the third feed roller (lO;) descends approximately vertically.Therefore, the above running path (P illusion slider Q6) [
The bending point (R+ is at the highest position).

To explain the false-twisting action in the wood false-twisting machine Q, the twist formed by the nip-type false-twisting device (7) is propagated to the first feed roller (4), and is then passed through the upright primary heater (
After being heat-treated in yarn cooling device 5), it is cooled in a yarn cooling device (14) and passed through a false twisting device (7). During this time, the undrawn yarn (
Y) is stretched between the first and second feed rollers +4) +8) and each balloon control brake) (13) (1
5), the running is stably controlled. The untwisted yarn (Y) leaving the false twisting device (7) has its distortion etc. removed by the secondary heater (9), becomes a textured yarn with stable yarn quality, and is turned into a winding para (Y). 18).

FIG. 2 shows details of the thread hooking device, and FIG. 3 shows the structure of the slider (16) used in the device.

The slider (1G) includes a retaining plate (22) with four annular parts (21) formed around it, four cylindrical sliding bodies (23),
The thread guide member (2) is integrally formed with a groove (24) around which the thread (Yl) engages, and convex portions (26) (26) are formed at both front and rear ends. (27
) is a kite rail that guides the slider (16), has a slightly longer dimension than the second balloon control plate (+3), and is integrally fixed along the back Q of the control plate (13). , and its upper end, that is, the part near the primary heater (5), branches out from the control play (13) and curves smoothly upwards, and the control play (+3) is straight up to the upper part of the -order heater (5). It extends to The second balloon control plate Q3) and the guide rail (the second force is a beam (
29) and 1 (31) installed on the frame (3), and the cross section of the guide rail (27) is bent into a U-shape to irremovably enclose the sliding body (23). and
A cross section Q of the second balloon control plate (13) is formed with an inverted U-shaped thread passage groove (32) passing through the thread. At the positions corresponding to the upper and lower ends of the guide rail (2η) of the beam (29H31), screw stoppers (33) (3
4), and at the upper end of the guide rail (27) there is further provided a bottle (36) which is urged to protrude by a spring (35).

The slider (16) slides its sliding body (23) onto the guide rail (
The convex portion (26) slides while being guided by the inner wall of the convex portion (27).
(The upper and lower limits of 26+ are set by coming into contact with the stoppers (34) and (35), but the slider (16)
A recessed hole (37) as shown in FIG. It is G-shaped to prevent falling and sliding.

Next, the thread hooker will explain the operation.

Before starting the yarn hooking process, the operator first pulls out the yarn (Y) from the yarn feeder (2), temporarily passes it through the first feed roller (4), and then passes it through the second heater (5). Bend the suction pipe (42) using the attached guide bin (41).
Let it be absorbed. At this time, the thread running path is a single point chain, 11
As shown in (PI), all threading work is carried out by an operator standing on the workbench (43). Next, the yarn (■) is cut at an appropriate point on the traveling path (PI) and transported from the yarn cooling device (14) to the second balloon control plate (15).
), the yarn is passed through the false twisting device (7) and the guide pin (17) to the second feed roller (8), and the end of the yarn is sucked into the suction pipe (42). The yarn running path at this time is indicated by the chain double-dashed line (P2), but at this time, the yarn (2) is incompletely nipped between the belts of the false twisting device (7).
Therefore, in this state, the yarn is given a weak twist called half-twist. Next, a device is used to hang the main thread, and the thread (
(P3) on the regular yarn traveling path (P3).

In other words, the slider (16) at the lower end of the guide rail (27)
) in the groove (24) of the thread guide member (25), and hook the slider (1G) onto the guide rail (
27) to the top end and stopped by the bottle (36), and at this time the thread (■ enters the heating area in the primary heater (5) for the first time and at the same time the first balloon control play) (13) Run inside. The slider mentioned above (1
For the movement in step 6), use the operating rod shown in Figure 4.

The operating rod has a total length of about 1200n and has a slider (1
It has an engagement FJ (4'f;r) which has an inner diameter larger than the outer diameter of the engagement platform (22) of
3) It is easily attached and detached.

When moving the slider (16), the operator must move the slider (16) on the workbench (4).
3) Handle the operating rod (44) on the top and its engagement ring (45)
The slider (1G) is engaged with the engagement plate (22)* and the guide rail (27) is slid along this, and the slider (1G) is stopped at its upper end and then engaged with the above. Release. Next, the yarn (Y) is brought into strong pressure contact with the first feed roller (4), and the wire yarn (Y) is drawn between the first and second feed rollers (4) (s).
4), water is supplied to start cooling the yarn α), and the false twisting device (7) is operated to bring the yarn (1) into a perfect nip state, and the wire yarn (2) is twisted normally. Give a number. Finally, the yarn (Y) is fed from the second feed roller (8) to the winder (++) via the secondary heater (9) and third feed roller (10) to obtain a wound package (18).

Although it is necessary to provide Q units for each unit, only one operating rod (44) is required for a plurality of units, and the manufacturing cost can be reduced accordingly. In addition, since no special equipment is required other than the guide pin (41) on the front side of the secondary heater (5), the inside of the heater (5) can be easily cleaned.

Since the i1 balloon control plate (13) is linearly close to the bending point (R), the control plate (13)
) and the bending point (R+) can be shortened, free running of the yarn can be kept small, and the control play) (13
) to ensure thread regulation. Also, the guide rail (
27) is branched from the first balloon control play N15) above the -order heater (5) and draws a smooth curve upwards, so when guiding the thread (2) to the bending point (R), the slider 06) Since the movement of the thread does not change suddenly, and therefore no impact or tension fluctuation is applied to the thread, there is no possibility of thread breakage or the like.

It is preferable that the guide rail (27) is provided parallel to the control plate (La) except for the curved part at its upper end. The two do not necessarily have to be integrated, and even if the means for stopping the slider (1G) is difficult, it is possible to remove the bottle (36j), attach the stopper (33) with a magnet, and replace the slider (16) with metal. (It is also possible to stop the attraction magnetically.)

Furthermore, the above stopping means is removed, a suitable guide bin is provided at the bending point (group position O), and the thread is threaded from the slider (1G) to the above guide bin at the highest G of the guide rail (2η).
It is also possible to devise a method that allows the delivery to take place. Furthermore, the operating rod (44) can be eliminated, a string or chain, etc. is connected to the slider (1G), the string, etc. is wound around a pulley or sprocket +1, and the string, etc. is run manually or automatically. It is also possible to move the slider (16) from G. Furthermore, the thread guide part 'kA of the present invention is not limited to the roller G, but may be of other shapes, such as a bottle or a ring, or may be one that bends the thread in a U-shape by using two thread guide parts. good.

As described above, according to the present invention, when threading the false twisting machine, it is possible to easily thread the thread and ensure that the thread is attached over the entire length inside the heater.
