[Detailed description of the invention] Device for splicing bundled yarn The present invention provides a pair of yarn feeding rolls, a hollow spindle provided downstream with a binding yarn bobbin. It is equipped with a spindle, a pair of pull-out rolls, and a winding device, and a pair of yarn feeding rolls and a hollow spindle. At least one fiber suction pipe that can be opened and closed is provided between the fiber wick and the fiber wick. The suction opening of this suction pipe is the point where the yarn feeding roll pair is tightened and the upper part of the hollow spindle. Relating to a device for splicing a bundle release, which protrudes into the area between the opening and the opening. .

In the prior art, two suction pipes are configured to be used as fiber blotting pipes. This type of design is already known (see West German Patent Application Publication no. (See No. 27, 53, 349). The suction pipe can be opened and closed on the slider. Thread cutter The fiber bundle is drawn into the suction pipe to eliminate the The first suction is returned to the position between the empty spindle and sucked into the other suction pipe. The suction airflow in the tube is interrupted by a slider, where the hollow spindle The winding yarn and the binding yarn present in the second suction pipe are activated. The fiber bundle is pulled out from the second suction tube, in this case the yarn balloon to form the entire fiber bundle. Since the suction air is interrupted in the first suction pipe, this suction pipe is free of air. , through the opening to reach the inside of the casing. In this case, the fiber bundle is a binding yarn and a winding yarn. It is captured by the thread balloon formed by the -, In this known embodiment, a housing with a binding thread bobbin is used.

In this case, the construction and space costs are increased, and in addition to this the binding thread bobbin is difficult to access.

Historically, after yarn breakage, the yarn was spliced using a slit to insert the yarn behind the exit roll pair. Other devices for splicing bundled yarns, which are performed by (See West German Patent Application No. 2960798). In this case, the thread holding device is necessary in the range of the outlet o-le pair, and in addition, the winding is performed when the spindle reaches the working rotation speed. Additionally, you must use a thread drawer sump connection device that is activated when reached. , measures are required to run the yarn into the exit roll pair and the drawer roll pair. The disadvantage here is that the constructional and construction costs are likewise high.

On the other hand, the problem of the present invention is that winding is an operation when re-splicing the yarn after the yarn breaks at the position. Reduced equipment costs and ease of workability while increasing operational reliability. The object of the present invention is to improve a device of the type described at the outset so that

According to the present invention, this problem is solved by providing a main conduit between the pair of yarn feeding rolls and the hollow spindle. A casing shall be provided, and the multiple fiber suction pipes shall open into the above main pipe. and carrying a closure in the casing which interrupts the suction action of the fiber wicking line. This problem can be solved by supporting the system in a movable manner. As a result, the yarn feeding roll pair ′ and The empty space between the empty spindle and the empty spindle is utilized in an optimal manner and the thread is spliced after thread breakage. This has the advantage that it can be used for various purposes. Hollow spindle and binding thread Accessibility to the bobbin is ensured and requires only small constructional outlays.

In this case, the closing member can be, for example, a slider, a flap mechanism arrangement or a hose ramming mechanism. can be formed by jin According to another feature of the invention, the closure member has a main fiber wicking channel in the casing. It is movably supported in a position opening into the conduit.

According to another embodiment of the invention, the closure element is designed as a tube. Furthermore, inside the casing A yarn suction pipe that opens into the main conduit behind the frontage of the tomb fiber suction conduit in the fiber running direction. There is a conduit for the air. In this case, this pipe body is connected to the main pipe inside the casing. It is supported rotatably about its longitudinal axis laterally to the wall, and It has a cutout inside. Therefore, fibers can be absorbed in the desired direction simply by rotating the tube. The outlet pipe and the main pipe can be closed.

According to another feature of the invention, the yarn suction pipe is arranged in the casing in the fiber running direction. The twister acting in the main line behind the opening is provided with a nozzle. This invention With other configuration possibilities, the pipe body can be axially aligned with this main pipe in the casing with respect to the main pipe. The fiber suction pipe and yarn suction pipe are closed in the notched wall. The device is equipped with a sheathing member that is rotatable and is rotatable about its longitudinal axis. With this configuration, it is possible to make efficient use of space and to use only the rotation of the tube each time. Functionally reliable closure of the pipe is achieved. At this time, the covering member (d) is attached to the fiber blotting pipe. It is installed at a position of 90 points with respect to the coating member of the yarn suction pipe, and the pipe body (r!, one arm that is rotatable about its longitudinal axis by 90 pa each) Due to the other configuration of the light, the pipe body is also axially connected to the main pipe within the casing. In addition, the casing is located in the passageway and is movable in the direction of the longitudinal axis. Other features of Ming make it movable relative to the hollow spindle, and the hollow spindle The lower end has a sealing area that can be brought into airtight contact with the opening of the hollow spindle. It is growing. This advantageously increases the suction action, since the suction opening The mouth opens at the top of the hollow spindle (after C, it comes into airtight contact) Other features of this study (from τ, the fiber suction pipe is direct and the yarn suction pipe is long. A thread guide tube leads into the suction line for the fibers and threads. At this time, The long thread guide tube is designed as a loop channel.

On the other hand, the fiber suction pipe and the yarn suction pipe are communicated with each other via a blocking mechanism. is possible. This blocking mechanism is designed, for example, as a slider, which The holder is provided with at least one cut-out opening and has at least one open position or a closed position. can be moved to any position. Furthermore, providing a sieve in the yarn suction pipe, It is also possible to provide two passage openings in the slider, one in front and one in the rear of the sieve. 5. Other features of the invention that are particularly suitable for thicker yarns The yarn suction pipe is provided on the side of the hollow pipe opposite to the opening of the fiber suction pipe. and, in addition, the closing member designed as a slider is capable of absorbing the fibers. It shall be possible to move laterally into the main conduit above the opening of the conduit and suction conduit. This allows the broken yarn to be guided closer to the yarn supply roll pair and the long fibers to be processed. This also eliminates the possibility of undesirable tightening of these fibers during splicing. The advantage is that a compact installation can be obtained without any problems – with this, the dimensions Although the structure has been simplified, it has been made low and thick so as not to take up space. A thread splicing device suitable for thread splicing has been created. The other 11 points (・; 1, when thread splicing, the length of the fiber yarn) is 1 compared to the length of the yarn. In another configuration of the present invention, 1 is that the main control is performed by the slider. The passage can be closed in an air-tight manner, which is advantageous for hollow spindles. An increase in the low pressure at is achieved, making it easier to suction the ends of the yarn during kneading.

According to another fourteen features of the present invention, the slider is provided with a tongue, and this tongue piece is attached to the slider. In the pulled back position, the thread suction pipe works together with the wall portion of the yarn suction pipe. By suctioning the cross section and holding the twisted thread in a flexible state, a narrow passage opening is obtained. narrow it down.

Furthermore, the slider consists of a sleeve that is slidable in the bore of the casing, this sleeve The front and rear sides of the The wall oriented towards the mouth (opened and bent, thereby creating a closed part) A simple composition of materials can be achieved. According to another feature of the invention, the slider is spring-loaded and connects the yarn wicking conduit to the fibers. The opening of the suction pipe is locked at the position where it communicates. The blotting action of this fiber blotting pipe is applied at intervals from the opening of the fiber blotting pipe to the river. A closing member is provided which interrupts the tightening of the silk thread roll pair. Processing from one gland has a spacing that is thicker than the length of the fibers, The present invention will be explained in detail below with reference to embodiments illustrated in the drawings. FIG. 1 is a schematic side view of the device according to the invention, FIGS. 2 to 5 (d) The schematic side views, FIGS. 6 and 7, show two embodiments of the suction line, FIGS. 8, 9 and 7. and Figure 1o show three embodiments of the yarn suction line and the fiber suction line with a slider. Diagrams at different positions of 11, 12 and 13 are according to FIGS. 2 to 5 of the device according to the invention. side views showing the structural configuration in different ways; FIG. 14 is a front view of the apparatus according to FIGS. 11 to 13; FIG. 15 is a side sectional view according to another embodiment of the present invention, and FIG. 16 (d) is a side sectional view according to another embodiment of the present invention. Side sectional views of the shaping, Figures 17 to 20 (and different ways of shaping according to Figure 12) The plan view and cross-sectional view of the step, FIGS. 21 and 22, show two other embodiments of the present invention. Diagrams at different positions of It shows The device for splicing the bundled yarn shown in Fig. 1 is a yarn feeding roll 1, a hollow spindle Winding with a connecting thread bobbin provided with a trailing thread formed as a thread It is equipped with a spindle 2, a pair of drawer rolls 5 and a winding device 4, and furthermore, a winding device is provided. A tangential belt drive 8 for the spindle 2 is provided - a pair of yarn feeding rolls 1 A casing 5 is provided between the hollow spindle 2 and the casing 5. The inner chamber of is in communication with the suction line 7 via the connecting conduit 6.

A first embodiment of the invention, illustrated in various steps in FIGS. A main conduit 14 is provided in the main conduit, and a fiber suction conduit 9 is provided in this main conduit. The yarn suction pipe 10 is opened at the rear in the forward direction. The id is shown in Figure 2. The fiber 1 is drawn out through a pair of drawing rolls 3 and wound on a bobbin of a winding device 4. 1 shows normal running.

FIG. 3 shows the state after thread breakage occurs. continues to be supplied, and is no longer given twist and knotted. Discrete fibers that are not bundled: ・Dominating the inside of the pipe 7 and comingllia The fibers are blotted out through this fiber wicking channel 9 by the suction air acting through the fiber wicking channel 9. It will be done.

In Fig. 4, the broken end of the thread 12 is removed by hand during the preparatory stage for thread breakage removal. Alternatively, an automatic device is used to wind the yarn from the bobbin of the winding device 4 to the suction line 10. )! After that, the yarn is further fed back 3 and a part of it is added to this suction pipe 10. It gets sucked in, Figure 5 shows the original process of thread cutting; It shows. The opening of the fiber suction pipe 9 is closed by the closing member 131c. Therefore, the individual fibers 11 that are continuously supplied are sucked into the fiber suction pipe 9. is interrupted. As a result, the fibers are guided into the suction range of the yarn suction pipe 10. , at this time, it is combined with the thread 12. The yarn 12 is taken up at the same time as the fiber suction pipe 9 is closed. is started again by the pair of draw-off rolls 13 and thus the fibers adjoining the yarn 12 The fibers 11 are tied into a thread and pulled out together with this thread. This process is continuous, and the threads run out. Winding is a process in which the filament is formed in parallel with the filament bobbin. It is activated before the winding of filament 2 starts. When the spindle carrying the spindle is started, take-off takes place at a very slow speed. .

In this case, the bundling of the fibers into the thread 11 occurs in the tangential direction, with the threads under tension. Winding with a thread is performed by twisting the thread with a thread.

This application and removal of the temporary weft to the yarn 12 of the fiber 11 is carried out behind the opening of the yarn suction pipe 10. (lower part) in the main conduit 14 in the direction of fiber running; The twisting is done by the nozzle 16, and this twisting is done by the nozzle! 4m fiber suction pipe 9 This strand is connected at the same time as it is closed, and is cut off again after the thread breakage has been eliminated. The nozzle is 1, which is shown in detail in Figures 11 to 14. The preparation of the binding thread, which is generally torn in the same way, is not shown in the figures of this drawing. It was. The torn end of the bundled yarn is stopped beforehand, and the yarn is wound on the hollow spindle. The winding is fixed on the immovable machine frame adjacent to the thread spindle 2. Ru. Then, winding is carried out when the yarn spindle 2 is activated just before the fiber blotting conduit 9 is closed. When the thread is pulled out, the thread is wrapped around the thread 12, and this winding is newly accumulated when the thread is pulled out. It is transmitted to the thread that is inspired by the shukui that was created.

After the yarn splicing process is completed, the fiber blotting tube S49 is opened again, thereby allowing other yarns to If a break occurs, IC continues to supply the fiber that is no longer spun. Blotting is performed. In order not to weaken the suction action of the fiber suction pipe 9, the yarn suction pipe It is advantageous to intersect section 10 after removing the thread breakage. The thread piece 12 is drawn into the pipe 10 (twisted back) in a relatively large length. Therefore, this fiber piece 12 is connected to the suction pipe 7 (the first (Figure) must be distributed so that it is separated from the fibers and retained. . , in this case the three embodiments according to FIGS. 6 and 7 and FIGS. 8 to 10 According to FIG. 6, the yarn suction pipe is formed as a loose pipe 10'. This loose passage leads into the integrated suction conduit 7 of the fiber and yarn sump. This suction line is likewise directly connected to the fiber blotting line 9. this place The length of the joining loop path 10' is such that it accommodates the longest piece of thread that is sucked in as far as possible. Moreover, the end of this thread piece does not protrude into the suction pipe 7.

According to FIG. 7, divided suction lines 7 and 7' are provided. In this case, debt The suction line 9 connects to the suction line 7, and the yarn suction line connects the yarn to the suction line 7 via a conduit 10''. It leads to a suction line 7' for the purpose.

Open these incisions Between the mouths there is a slider 40 with both openings 46 and 47. this place In this case, FIG. 8 shows the normal position, in which the thread is pulled by position 1 of the slider 40. The suction line 10 is cut off from the intake air.

All the intake air acts on the fiber suction multi-pipe line 9, so that when a yarn breakage occurs, it is immediately removed. This allows all of the unspun fibers to be absorbed.

FIG. 9 shows the yarn suction state. , in this case the slider 40 is at position ■ −1 In this case slider 40 id is guided completely to the right and therefore The communication between the lines 9 and 10 is behind the sieve 41 through a coexisting channel 42. -4 4 and 46. This allows the chamber to communicate with the intake air behind the sieve 41. In this state, the threads are sucked in and accumulated on the sieve 41, from which the threads are taken out and connected. It is taken up again at the start of the piecing process.

Normally, the yarn replenishment accumulated on the double sieve 41 is completely taken off, but the yarn replenishment - There is no problem in the case that fiber residues are not collected together and accumulate on the sieve 41. . To remove any such buildup from the sieve and to clean the sieve, place according to Figure 10. A position ■ is formed.

In this position, the slider 40, which has been moved completely to the left, is attached to the manual grip 50. Cut through the opening 47 and connect the openings 43 and 45 to each other. The space in front of the front 141 is communicated with the intake air, and at this time the fiber residue accumulated on the sieve is removed. There are many possibilities for the movement of the sieve through which the sieve is sucked out. In the case of the illustrated embodiment , the slider is held in the missionary position by the force of two springs 52 and 53. , 1. by the manual grip 50. pushed against the force of i;q and brought to another position 7?1. - In this case, at least the position according to Figure 9 (position ■) is provided, the slider 40 is moved there by a correspondingly controlled working element.

In order to suck up the fibers in both pipes 9 and 10, the broken end of the thread is placed in the eye area. It is also possible to provide only one conduit, which also serves the purpose of cleaning. In this case, the work progress is as follows. The work station is as shown below. If thread breakage occurs, the fiber that is being fed The fibers are first passed through a fiber drafting machine to eliminate any cuts that are drawn out through the blotting pipe. supply to the structure is interrupted. After the drafting mechanism idled, the suction multi-pipe line broke at this point. In this case, where the end of the thread is suctioned from the bobbin, the main line is connected to the opening of the suction line. For the purpose of increasing the suction action between the opening and the pair of yarn feeding rolls, the closing part, be done.

The end of the yarn is sucked into the suction pipe, and winding is done by pulling the fiber additive after the yarn comes into contact with the yarn. The supply to the stretching structure is restarted, and fibers are again supplied into the main pipe from the pair of yarn supply rolls. As soon as the seizing is done, the spindle is activated and thread withdrawal begins again. The subsequent work is carried out as described above. In the case of the shape shown in FIG. 21 2 and FIG. 22 1/ζ of the present invention, the casing 5 (7i, in the winding process, the fibers 11 fixed to the thread pass through while being falsely twisted by the thread.

After one suction is completed, the slider 60 is returned to the starting position 6 where it was placed in the 21st position. At this starting position, the slider 60:・Well, this slides the thread by the force of the spring 65. Tighten in a regulated state between the 60 tongue pieces 80 and the wall portion 81 of the eyelid conduit 10. In this way, the thread performs other functions, and therefore, the thread is suctioned and lifted under tension in the second step. The first fiber suction pipe 9 is opened again, and the fiber 11 is spliced. The feeding to the ginning device is started again, in which case the fibers are added to the l$ fiber after leaving the yarn feed roll pair. In the suction phase of the single thread splicing process, which is sucked into the suction pipe 9, the hollow spindle 2 is in contact. The linear drive belt 8 is actuated by being crimped, and the fiber suction pipe 9 is opened again. Starts when the fiber suction pipe 9 is closed and the thread is pulled at the same time. Taking is started by take-off roll pair 3 = therefore in contact with the yarn The fibers 11 are bundled into the system and taken off with this thread - i.e. the process is continuous. , allowing continuous formation of threads.

A special arrangement of the fiber take-off line 9 and the fiber eye removal line 10 as well as the movable slider 60 Depending on the position, thread splicing can be done even for thick threads. In this case, the suction The wicking effect is such that even these thick yarns made of bristle jutan fibers can be sucked in. (In the case of large yarns, the broken strands or threads can be The tightening of the thread roll pair is guided close to the wire, thus ensuring good binding of the fiber threads. In addition, it is possible to achieve this without any hindrance when the thread end is already introduced into the thread eye passage. The suction of finely spun yarn is not maintained. A holding force acts on the suctioned end of the thread, and Therefore, the yarn is taut during the splicing process, and the yarn is taut without forming loops. It is drawn out from the 1σ conduit.

Due to the compact structure, a space-saving unit is achieved and this In addition, the air consumption is advantageously reduced to a minimum, Fig, 77 Fig, 11! Ft’g 79 Rg, 20 International Research Report Notice
