Description

[Detailed description of the invention] Short warp manufacturing equipment Technical field The invention particularly relates to clothing designs as defined in the preamble of claim 1. A short warp yarn (warb) manufacturing device for warp yarns, and This invention relates to a method for producing short warp yarns such as

Background technology In the short warp manufacturing device known from DE-O98821534, threads of different colors are successively produced. are wound in juxtaposition, and the yarn sheets thus obtained cover all It is cut transversely at the end of the winding operation. The yarn guide follows the outer contour of the winding device. while the frame of the winding device is fixed. Winding on winding device The attached surface is movable along the outer circumferential contour of the device, and can also be moved in the direction of movement of the yarn guide. is placed across the The thread guide follows the outer contour of the winding device. It is fixed to a rotating belt that circulates. The weaving thread guide is used to guide different threads from the warp shaft rack. In the thread transfer device that receives the These threads are wrapped on a wrapping device once or several times based on a given garment design. can be done. Controllable located behind the thread transfer device along the winding direction An ejector (discharging device) pulls the yarn from the yarn guide and moves it around the winding device. It is used to rotate.

The advantage of short warp manufacturing equipment as described above is that the different The threads are individually and continuously wrapped around the winding means by means of thread guides. At the same time, the thread to be wound is moved in a direction transverse to the winding direction with respect to the winding means. Because the bobbin is moved, short warp threads can be set using only one bobbin for each color. child As a result, significant savings in working time and materials are achieved.

In addition, the well-known short warp device is used when changing the thread, that is, when the last Idle movement of the thread guide between the discharge of the thread and the picking up of the next thread by the thread guide In addition to the unavoidable loss of time, Since the sheet is continuously moving in a direction transverse to the winding direction, the thread gap is pulled. It has the disadvantage of causing As a result, the maximum possible warp thread width is reduced. .

The object of the invention is achieved by the features recited in claims 1 and 7, respectively. achieved.

Disclosure of invention According to the invention, during the last circulation of the previous thread when changing the thread, the thread transfer device The rotary wheel, movable over the area of Move the next thread that has not been moved to the transfer position. This turning wheel is the weaving thread guide. To enable yarn replacement without causing idle movement of the cord. This creates patterned red threads. A significant reduction in manufacturing time can be achieved. If you change the thread once for each rotation, - As an example, 50% time is saved.

As a result of the removal of idle motion, the lateral movement of the weaving yarn sheet is The warp has a theoretical effective warp width without the problem of difficulty in controlling the drive for direction movement. corresponds to the width. In addition, the uniform winding of individual threads is achieved by unwinding them from the winding rod (unbeaming). (g) Removal of warp threads, especially when long warp threads or thread density is high, increases the action. becomes easier.

This is because the unfinished end of the yarn sheet is pulled out through the yarn that remains wrapped. Because it has to be done. On the other hand, in the meantime, there is a manual for correcting the warp width and thread distance. Stages can also generally be omitted. A further advantage of the solution according to the invention is that It is possible to modify and apply an old short warp thread loading machine at a relatively low cost. Even easier This structure ensures high operational reliability and keeps the warp loading speed constant. Ru.

In a preferred embodiment, the next thread is removed from the transfer position during the last circulation of the previous thread. It is moved to the standby position behind the previous thread discharge position, and after the previous thread is discharged, it is moved to the standby position. It is picked up by the yarn guide at the position.

During the last circulation of the previous thread and before actuation of the ejector, the thread transfer device transfers the next thread. A rotary wheel is provided to receive the thread, and the thread is moved so that the next thread is picked up by the thread guide. By holding the weaving thread guide in the standby position behind the thread guide, the weaving thread guide is held in the standby position behind the Later, the next yarn can be received, and virtually no idle motion of the yarn guide occurs. Wait By locating the machine behind the discharge position, structural changes can be minimized and This makes it easy to retrofit old machines.

In another embodiment, another ejector is provided ahead of the thread transfer device along the winding direction. After the operation of this other ejector, the rotary wheel is placed in front of the thread transfer device. It receives the previous thread from the weaving thread guide at the weaving thread guide and returns the thread to the thread transfer device.

In this way, the weaving thread guide can be used in a well-known manner in the area of thread transfer devices. can receive the next thread, and in this case too, no idle movement of the thread guide occurs. stomach.

Preferably, the rotary wheel is movable in the area of the thread transfer device to the rear of the ejector. It is a lever that pivots. Such a pivoting lever allows easy control of the weaving yarn. It can be controlled as desired in synchronization with the rotation of the guide.

The rotary wheel is pivotable about the axis of the winding means deflection device.

Such a structure is simple and can be easily retrofitted to older models.

In an advantageous development of the invention, the feed rate of the winding surface in the direction transverse to the winding direction is set smaller than the width of one thread per winding. In this way, the thread that can be wrapped Since the warp threads partially overlap, the unwinding action of the wound warp threads from the winding rod is obstructed. Without this, the warp width that can be manufactured is expanded relative to the predetermined width of the device.

Brief description of the drawing Figure 1 is a schematic front view of the machine with short warp threads, Figure 2 shows that the short warp threads are placed on the side of the winding device of the machine, and Figure 3 shows that the short warp threads in Figure 1 are placed on the side of the winding device of the machine. An enlarged view of the thread transfer device, 4a-4e are schematic diagrams showing different stages of the thread transfer device; Figures 5a-5f are schematic diagrams showing another embodiment.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The short warp machine 1 has frame parts 2 and 3 and a lower transverse connecting bar 5. this In the frame parts 2 and 3 of the A conveyor belt on which a changing roller 6.7 is rotatably supported and conveys the wound yarn. The conveyor belt 8 moves while being guided on the outer circumference of each direction changing roller, and each conveyor belt changes direction. The rollers 6.7 extend in a longitudinal direction parallel to the axis of rotation of the rollers 6.7. direction change roller 6.7 The yarn wound around the yarn is conveyed on the conveyor belt 8 in a direction transverse to the winding direction. Ru. The winding means 10 includes a continuous circulating belt 11 in addition to the reversing rollers 6.7. , this circulation belt is connected to the front end of each reversing roller 6.7 facing away from the frame 2. direction is changed by the pulley 12, respectively. The circulation belt 11 has a direction changer. The roller 6.7- guides the yarn to be wound around the roller 6.7 and changes the direction of the yarn. It has a weaving thread guide 18 which is fixed in position. Reference number 16 is the thread to be wrapped This shows a cover that functions as a guide member for the weaving yarn guide from the warp shaft rack 24. Guides the thread section which is directly taken in by the id 18.

The warp shaft rack 24 has threads 2 of different colors, for example, to produce short warps for multicolored weaving. 8 wound bobbins 25 are arranged. 6 threads 28 are each bobbin 25 It passes through the movable eye 1 and throat 26 and extends to the thread transfer device 19.

The thread transfer device 19 is pivoted upward to the transfer position indicated by II in FIG. It consists of a number of turning levers 20 that hold a predetermined thread in a standby state by The number corresponds to the number of bobbins. In other words, the turning lever 20 is The gate should be provided with at least as many threads of different colors to be processed. Turn The rotation thread 20 corresponds to the six threads 28 sent out from the warp shaft rack 24.

The free ends of the pivoting levers 20 are each provided with a hook 21 on which the thread is not hung. Ru. Each pivot lever 20 is individually and can be controlled independently.

In the area of the thread changing device [19, a rotatable rotary ring 23 is provided in a hinged manner, and It can be operated in synchronization with the operation of the circulation belt 11 and the ejector 32 by suitable control means. The rotating shaft of the rotary ring 23 is coaxial with the shaft supporting the lower boob 1J12. (I prefer it to be extended).

When replacing the thread, the turn/<-20 corresponding to the desired thread is the transition shown in Figure 3. The desired thread 28 then follows the path 30. Become. This is because one end of all the threads 28 is attached to the lowest conveyor belt 8 of the redirection rollerf. Clamping at a clamping point 27 located and moving together with the conveyor belt 8 This is because it has been done. Since the thread path 30 is located within the turning path of the rotary rotary 23, Therefore, when the rotary wheel 23 is activated, the rotary wheel picks up the thread located at the transfer position II. and then move it to the standby position II located behind the ejector 32 along the winding direction. + (Figure 2).

Another thread sent out from the warp shaft rack 24 corresponding to the pivot lever 20 in the rest position I Since the thread remains in the path 29, it cannot be picked up by the rotary wheel 23. circulation The ring belt 11 passes around the redirection roller 6.7 a predetermined number of times (this number of times is controlled, for example). After the circulation (set by the control means 36), the thread changing device Co-9 is The placed ejector 32 is connected to an actuator element, such as a pneumatic cylinder or a rotating magnet. Therefore, the ejector 32 is rotated to the position shown by the dotted line, and the ejector 32 is moved to the weaving yarn guide] Move within the path of 8. Therefore, the circulating yarn is transferred from the yarn guide 18 to the ejector. Received in 32. The tension of the thread and the action of trying to unwind the winding that has just been wound. The removed thread is transferred to the standby hook 2 of the turning lever 20 in the transfer position II. 1, and as a result no further rewinding operation is required. the last thread is discharged during its final circulation, and immediately after this discharge the next thread is moved by the rotary wheel 23. It is prepared in standby position II+ so that it can be picked up. In this way, the thread guide 18 can pick up the next thread immediately after discharging the last thread, eliminating idle motion. can be reduced to There is no idle circulation in the thread guide, and each thread is Since the formation of thread gaps between threads is eliminated, the maximum All possible warp widths can be used.

The path of the thread after being picked up by the thread guide 18 is divided into two parts.

That is, the portion extending from the warp shaft frame 24 to the weaving thread guide 18 and the weaving thread guide 1 8 to the last clamping position on the downward deflection roller 7, This clamping position is located at the end of the last winding in question. 6 threads first When picked up, its clamping position is the clamping point 27. warp axis The yarn portion extending from the frame 24 to the weaving yarn guide 18 is attached to the periphery of the guide sheet (cover) 16. The part that extends to the clamping point is wrapped while going around the circumference.

Figures 4a-4e show a total of 5 steps of yarn transfer not including idle circulation of the yarn guide. It is shown separately. In Fig. 4a, a total of 10 yarns a-k are connected to the yarn transfer device] 9, each of these threads can be selectively and individually turned. Using the pad 23, the thread k is moved from the transfer position II shown to the standby position II+. and is movable. In FIG. 4a, yarn a is guided by yarn guide 18. While the air is circulating, the ejector 32 and the rotary ring 23 are at rest. Ma The yarn k is moved to the transfer position II by the turning lever 20, and the yarn a is moved to the transfer position II. During the later circulation, located in the area of the upper deflection roller 6 as seen in Figure 4a. are doing. Of course, the circulation The threads may also assume other positions than those shown in Figures 4a-4e.

While the yarn a continues to move toward the yarn transfer device 19, the rotor 23 moves as shown in FIG. As shown in b, it is turned to the standby position I11.

In the next stage shown in FIG. 40, the yarn guide 18 holding the yarn a is moved Before reaching the sewing device 19, the swivel 20 for the thread is swiveled back to the rest position I. be done. Furthermore, the turning leno (-20) for yarn a is moved to transfer position II.

By simultaneously operating the ejector 32, the yarn a is removed from the yarn guide 18. The yarn is removed and caught by the hook 21 of the turning lever 20 for yarn a. Here, hang The yarn guide 18 with no attached yarn is located immediately behind the ejector 32. The yarn k can be picked up from the rotary wheel 32 in the standby position II (FIG. 4d). child Since the thread can be replaced immediately, idle movement of the weaving thread guide 18 can be avoided. Ru.

FIG. 4e shows that the ejector 32, the rotary ring 23, and the turning renocou 20 for the thread a are each It is shown turning back to the rest position. When thread k is making its final turn , the next thread e has already moved to the transfer position II, and the next thread e has already moved to the transfer position II, corresponding to each previous step. The cycle repeats.

Wreaths protruding from the frame 2 in a direction transverse to the winding direction 14.1 5 forms a weft insertion opening and is driven by a control means 36.

Another embodiment of the invention will now be described with reference to Figures 5a-5f.

Figures 5a-5f illustrate yarn transfer variations that do not include idle motion of the yarn guide in another embodiment. In order to explain each stage of the process, it is divided into six parts in total. Fruit of Figure 4a-4e In addition to the embodiment, another second ejector 34 is provided, which is connected to the first ejector 32. The pulley 12 of the lower redirection roller 7 is located on the opposite side in the diametrical direction. . In FIG. 5a, thread C has made its final circulation and is determined by the second ejector 34 It is located in front of the yarn transfer device 19 and just before the discharge position Iv. At this point , the next thread f has already been moved to the transfer position II in the thread transfer device 19. . The second ejector 34 is then in its operating position. The rotor 23 is in the winding direction. The transfer position is located forward of the second ejector 34 when viewed along the line.

At the stage shown in FIG. 5b, the yarn C is received from the yarn guide 18 into the second ejector 34. The yarn C is removed due to the tension of the yarn and the action of moving in the opposite direction to the winding direction and trying to return. It is caught by the rotary wheel 23. At this time, the weaving thread guide 18 is in a state where there is no thread. , moves inside the yarn transfer device and picks up the waiting yarn f.

In FIG. 5C, the yarn guide 18 has already picked up the yarn f and the first ejector 32 It's passing by. At this point, the first ejector 32 is actuated while the second ejector Zector 34 returns to its rest position.

At the stage shown in FIG. 5d, the pivot lever for thread f has returned to its rest position I. On the other hand, the previous swivel lever for thread C has been swiveled to its transfer position.

Next, the rotary ring 23 holding the thread C passes through the first ejector 32 which is in an operating state. As a result, the yarn C descends from the discharge position V in the opposite direction to the winding direction. and is received by the pivot lever for yarn C in the transfer position.

Thereafter, the rotary ring 23 is rotated forward from the second ejector 34 and returned to the first position. ejector 32 is swiveled to its rest position, and the swivel lever for yarn It is moved to position I (Fig. 5f). Furthermore, when the thread f is making its final circulation, Fig. As shown at 5f, the second ejector 34 is pivoted into the operating position and the threading pivot The lever is moved to the transfer position. Here, Figure 5f corresponds to Figure 58. Subsequent cycles are then repeated based on each of the above steps.
