Description

[Detailed description of the invention] This M Meiha is a method for mechanically disassembling yarn.
ble) relates to a splicer device for recomposing.

The device of the invention can operate according to the method described in part in European Patent Application No. 0039609, published on November 11, 1981.

In the device of the above patent application, the device used for untwisting and retwisting the yarn consists of a pair of rotating discs.

Furthermore, in order to perform an aplice in said device, the strings of yarn to be spliced (Bract) are introduced between the open disks and are twisted in two mutually intersecting directions diametrically of said disks. will be distributed to.

These discs are then brought close to each other and activated in the first phase of the working cycle, rotating in mutually opposite directions to effect the untwisting of the thread strands.

After removing the extra ends to be taken out of the thread and forming the remaining ends at each end of the thread inside the disc, each disc is actuated in the opposite direction to that in the first phase of the working cycle. They are forced to retwist.

Due to the matching of the disk types of the device used for untwisting and retwisting the yarn, the two yarn cords constructed between the disks will, if the device works properly, at least in the untwisting phase. However, they must take positions along the diameter of the disks that intersect with each other inside the disk.

This has the problem of causing interference of the ends of the yarn at the intersection, and of incomplete shielding and crowding of the fibers at the remaining ends. Such disadvantages have an unfavorable effect on the quality of the splicing performed by the device.

The object of the present invention is to provide a splicing device for mechanical yarn untwisting and retwisting, thereby overcoming the aforementioned technical deficiencies and providing splicing of excellent quality.

One advantage of the invention is that the untwisting takes place at a location where the threads do not interfere with each other.

Another advantage of the present invention is that, depending on the type of yarn to be spliced, the length of the splice can be varied to suit the fiber length.

In the present text, the terms "untwist" and "retwist" refer to the operations of removing the twist contained in the yarn and reforming the twist, respectively.

Therefore, in the following text, untwisting refers to an operation that can sufficiently untwist the yarn to a value of zero or twist in the opposite direction, thereby achieving a reliable starting value of 100% or more. shall mean.

On the other hand, retwisting refers to an operation for restoring the twist of spliced yarn, which can be as harsh as, or even stronger than, the original twist.

According to one feature of the invention, the untwisting and retwisting operations of the two threads are carried out by an untwisting and retwisting device. - According to the present invention, the l11ji! The retwisting device consists of opposing belts or pads facing each other and movable in opposite directions, with the yarn in engagement between them, otherwise said untwisting retwisting device It consists of a rotating device, such as a cylinder or disk provided with grooves with which the thread at least temporarily cooperates, or a rotating gripping device or corresponding mechanical means.

According to another feature of the invention, the device according to the invention conveniently provides a point for tightening the untwisted cord of yarn so that the remaining lengths of yarn do not fly out of the device itself. and an intermediate tightening device as determined.

The said tightening point is therefore separated from the untwisting and retwisting device in relation to the length of the fiber itself so that the fibers of the remaining yarn ends do not protrude from the device itself.

According to a further feature of the invention, the device includes a device for grasping and tearing off the excess thread end, and preferably also a device for discharging this thread end.

The picking and tearing operations of the excess yarn end ensure that the yarn is tightened by the intermediate tightening@1 mentioned above, and the untwisting device applies a small pressure on the yarn to assist in the picking action of the fibers. It is advantageous to carry out with little or no pressure.

Due to the picking and tearing action carried out in the process, the remaining fibers at each end are frayed into a tapered shape, which aids in bonding and cooperating with the fibers of the yarn near this end. Become.

Splicing is then completed by retwisting the two connected yarns. According to a further feature of the invention, this is carried out by a retwisting device which preferably cooperates with the untwisting and retwisting device in the retwisting phase.

Said retwisting device is arranged between the untwisting and retwisting devices. These can be formed as belts, disks or plates, or in other shapes, each having a surface capable of cooperating with the facing surface of the retwisting device.

If the retwisting device is disc-shaped, as described in more detail below, this device may be flat-shaped;
Alternatively, it can have contour portions of various shapes.

If the retwisting device takes the form of a sliding belt or pad, it may be of flat form or of various forms with sectors or sections or ridges.

One retwisting device can be made to cooperate with another similar retwisting device, or with another new retwisting device.

The retwisting device may also include a processing device that can act on the light itself during the retwisting phase.

The processing device may consist, for example, of diagonal sectors or ridges or protrusions if the retwisting device is flat; otherwise, if the retwisting device is disc-shaped. If so, variously arranged circular sectors,
Alternatively, it may consist of spiral sectors.

If such a processing device is provided, the device may be used to substantially tangentially, or preferably tangentially and axially, from the midpoint of the intervening strands towards the green part of the yarn in a uniform forward path. allowing a continuous gradual re-rotation action that acts incrementally along the axis of the thread in the direction and on the light itself,
It is something that

The pressure exerted on the yarn causes a mechanical concentration of the fibers and also allows the fluffy portions of the yarn to collect against the fibers, resulting in particularly good bonding conditions.

In the device of the invention, the retwisting devices may be paired such that opposing retwisting devices are both of the same type or of different types.

According to a further feature of the invention, the device may include auxiliary devices. This auxiliary device can, for example, heat the spliced yarn cords, thereby stabilizing the splice itself and keeping it in a substantially constant state over a long period of time.

Said heating effect is important since the equipment used to produce the required heating effect is not relevant from the economic point of view of the invention.
It can be carried out by microwaves, electrostatic or dielectric action, heated or radiant plates, electrical discharge action, concentrated fluids, and the like.

Alternatively, said auxiliary device may produce a mutual crowding action of the fibers of the two threads, whereby suitable devices such as combs, toothed or brush devices, or mixtures thereof, may be used. Interengaging devices may be included between the auxiliary devices.

Said auxiliary equipment may also include a nozzle (in which a liquid under pressure, possibly with a certain temperature and/or additives) is injected.
The device may include one or more.

The aforementioned auxiliary device preferably acts between and within the intermediate tightening device, but it can also be activated at any desired location within the untwisting and retwisting device.

According to a further feature of the invention, the bottle, shaft, stud,
The protrusion or equivalent device can be configured to cooperate with at least one untwisting retwist IIw and can carry out the task of bringing the yarns together and pressing one of them onto the other. can.

According to the invention, various means for moving the untwisting and retwisting device, means for activating the retwisting device, means for activating the device for displacing at least one yarn in the i direction, and a fixed miyota tearing device are provided. The means for tightening and displacing can also be achieved by the cooperative action of cams, or levers, or jacks, or other mechanical means of known type, or a combined combination of said means. It is possible.

Desirably, the untwisting retwisting device and the retwisting device operate in a cooperative relationship such that the movement of one of them has an effect on the other.

Therefore, the present invention is carried out by an m splicing device for mechanically untwisting and retwisting the yarn, whereby the splicing device includes a device for untwisting and retwisting the yarn to be spliced; is an untwisting action at a position where they do not interfere with each other, and an action to remove and discharge the excess end of the thread.
Furthermore, subject to the retwisting action, this splicing device is characterized in that it includes the cooperative action of queen elements. That is, 0

It consists of a 2 to 11 untwisting/retwisting device 12, and a device f13 for fixing the excess yarn end and tearing it. (FIGS. 1 and 2) Said pairs 11., also referred to below as "belts", are arranged so as to be suitable for the length of said threads 20, 21 if it is desired to form a splice. The belt device 112 that makes up the threads 20,2
1 can preferably be spaced apart from each other in the longitudinal direction.

In the case shown, said belt device 12 is a pulley device f operating in this example in conjunction with a belt 15.
It has been extended to 14.

According to the invention, it is envisaged that suitably rigid sliding surfaces (not shown) are arranged on the pulleys 14111 of each belt 112 along said belt section 16,
such that it can resist deflection of said portion 16 of 2.

The belt 112 is actuated in such a way that said facing portions 16 run in opposite directions, thereby producing a rotational movement of the threads 20, 21 between each pair 11, which rotational movement is coupled with the associated running of the belt arrangement 112. Depending on the direction, the untwisting or retwisting of the part of the yarn 20.21 to be spliced consisting of the length between the pairs 11 of said belt devices 112 is determined.

The construction of the belt device 112 used in the untwisting and reburning of the threads 20.21 to be spliced preferably allows said threads 20.21 to be arranged in parallel inside the device 1o.

The excess thread ends 120, 121 are released by the fixing and tearing device 18 and are discharged by the discharge device 29.

Thread 20.21 is then 'belt device! 112 and the retwisting belt @w124 mutually retwist (FIGS. 10a and 10b), and the intermediate tensioning device 23 is released.

FIG. 11 shows another modification of the invention.

According to this modification, the untwisting and retwisting device 12 can be used to untwist the yarn 20.
It consists of a cylinder device or cylinder 212, which is provided with a radial cutout 31 in which the cylinder 21 can be positioned and held. This cylinder 212 is the retwisting device 2
The cylinders 212 are arranged at positions facing each other in the diametrical direction on the outside of the cylinders 212, and the axes of the cylinders 212 are aligned.

Said cylinder 212 also has on its outer side a toothed sector 32 that meshes with the drive rack 132 and is circular in this example and located on the outside of the retwisting device 24 .

In the illustrated embodiment, the retwisting device 24 is a disk-shaped retwisting device 224.

The treatment @ 1125 is configured on at least one retwisting device 224 and may be of the bright line type or have concentric sectors, eccentric rings, or annular sectors eccentric with respect to one diameter, etc.

1st year of middle school! ! Tightening@-23 is contained within and cooperates with processing device W125, and is arranged and operated in the manner described in detail herein.

According to the invention, the intermediate tensioning device 23 can be independent, as described above, or it can be obtained in cooperative relationship with the processing device 25.

The middle 1IIW4 tightening device 23 may have a slightly larger height and exhibit elasticity. For this reason, after initially acting with the intermediate tightening device 123, the disc-shaped retwist @ 11
When 224 comes together before the final retwisting operation, a relatively large pressure will be used to activate the processing device 25.

In the illustrated embodiment, the cylinder 212 is supported by a bracket 33 to which the cylinder 212 is coupled to an adjustment device 133, which may be a mechanical or pneumatic adjustment device or another type of adjustment device. Therefore, it can be moved diametrically relative to the retwisting device 224 so as to adjust the length of the threads 20.21 affected by the splice.

The fixing and tearing @w18 may be a mechanical device 1118, for example, a thread 2 held by a pair of rollers 218, 318.
0 or 21, the rotary movement of the rollers 218, 318 can be stopped so as to hold the thread 20 or 21, otherwise the fixed and fixed Rip Shinsou @18
may be a pneumatic actuator 418.

FIG. 11a shows, by way of example, a device 218 and a device 418, the latter being in the case of the thread end 1 to be torn off.
It consists of a suction port that mates with the loop 34 to further improve the fixation of 20.

In this example, the suction port can be rotated around the pivot 35 in order to carry out the picking and tearing operations of the yarn end 120 discharged from the ejection device 129.

The thread 20.21 engages in the groove 31 of each cylinder 212 and in the fixing and tearing device 18, so that said thread 20.21 is moved by the stationary thread guide 36 and by the movable thread guide 136.
They are arranged in a parallel positional relationship.

If the movable thread guide 136 is attached to the fixing and tearing device 18
is not necessary if the threads 20, 21 are placed next to each other by a suitable lateral movement.

Rack 132 has yarn 2.0.
21 is rotated so as to untwist it to a required angle.

The threads are then brought into juxtaposition with each other by movement of devices 11B and 136 in the direction of arrow 37.

At the end of the untwisting operation, the notches 31 are present in the plane of the yarns 20.degree. 21 and act inwardly, making it possible to force the yarns together.

At this time, the yarns 20 and 21 are in opposite positions and the retwisting device 2
It is tightened by an intermediate tensioning device 23 which cooperates with a disc-shaped retwisting device (not shown) facing 24.

The pinching and tearing action exerted on the yarn ends 120, 121 is carried out in this example by movement of the fixing and tearing device 118 or 418 in the direction of the arrow 38, the groove 31 being located on the yarn 2o, 21 is rotated by rack 132 so that it does not dislodge from groove 31 during picking and tearing operations.

However, it is also possible to imagine the movement along the axis of the thread or the axis of the joint during one day of the fixing and tearing device, as well as its rotational movement.

The yarn ends 120, 121 are discharged by a discharge device 129, but this operation is performed after the binding w18 is released if the device 18 is the mechanism 118.

At this time, the rotational movement in the opposite direction to the direction of the initial rotational movement cooperates with the operation of the retwisting device 224 to twist the cylinder 21.
2, at least one of said devices constitutes a processing device 25 in order to obtain the required retwisting action of the two threads 20, 21.

According to each illustrated embodiment of the invention, an auxiliary device 39 is contemplated.

A possible arrangement of this auxiliary device 39 is shown in FIG. 12 in conjunction with the disc-shaped retwisting device 224.

Although several preferred configurations of the invention have been described herein, many modifications can be made without departing from the scope of the invention.

Each part can be added to, subtracted from, or changed in shape and/or proportions.

The various configurations described in the text and shown in the drawings can be combined. Further modifications may be made by those skilled in the art without departing from the basic idea of the invention.
