Description

  The present invention provides a package frame for rotatably holding a traverse winding package, a yarn supplying device for traversing the yarn wound on the traverse winding package, and a yarn end coupled to the traverse winding package. The invention relates to a method for operating a work site of a textile machine for manufacturing a traverse package, comprising a device for preventing the traversing of the surface of the traverse package when interrupted.

  Furthermore, the invention relates to an apparatus for carrying out the method described above.

  When manufacturing fiber packages, at least two conditions must be met, as is known. For one thing, the relevant fiber package has to be rotated, and for the other, the yarn wound on the package has to be traversed along the package axis. In this case, a so-called “twill wound package” can be manufactured by relatively quick traversing of the yarn. This twill package is characterized not only by a relatively stable package body, but also by good delivery characteristics.

  Therefore, in a modern textile machine that works at a high winding speed and manufactures a traverse package, such as an automatic traverse winder, the traverse speed of the yarn supply device is also set to be extremely high.

  In automatic traverse winders, various yarn feeding systems are known for generating a traversing motion of the winding yarn. For example, so-called “thread guide drums” are very popular. This yarn guide drum generally also provides circumferential drive for the traverse package. However, this type of yarn guide drum has the disadvantage that the same supply angle is always applied irrespective of the package diameter. This results in a so-called “wrapping ribbon” in a specific rotational speed situation between the package and the drive drum if no special measures are taken. This wound ribbon leads to significant problems during later feeding. Furthermore, in the case of such a yarn guide drum, in the case of winding interruption, especially when the yarn breaks or when the controlled clearer is cut, the yarn end coupled to the traverse package, the so-called “upper yarn”, There is always a danger of not rolling up on the surface and falling to the side of the yarn guide drum. Such yarns positioned to the side of the yarn guide drum after yarn breakage are often referred to as fallen yarns. Such fallen yarns can no longer be handled by the yarn pick-up nozzle at the winding site and therefore require manual operator intervention, so such fallen yarns are preferably avoided as much as possible. .

  Furthermore, it has been known for several years that the rotation of the traverse package and the yarn feeding device are separated in terms of drive technology in order to be able to form a set winding ribbon, for example precision winding or step precision winding. It has been. In this known apparatus, a traverse package held on a package frame is placed on, for example, a driving roller. This drive roller is defined by the associated drive and can be loaded, and entrains the traverse package via a friction connection during the winding process. In this case, the associated yarn supply device also has its own drive device.

  German Offenlegungsschrift 1 858 548 describes a yarn supply device with a finger yarn guide which is loaded, for example, by an electromagnetic drive. In this case, the amount and direction of the driving moment of the yarn guide driving device is adjusted at every stage of movement by controlling or adjusting the supplied current.

  This is done by a control computer, preferably a take-up computer. This control computer controls the current intensity and the current direction in relation to the angle and time by a settable program. In this way, for example, the desired supply angle, traversing width or traversing end point of the yarn can be adjusted each time. In this case, an appropriate sensor mechanism, preferably an angle sensor, detects the respective angular position of the yarn guide finger and checks the maintenance of the target value, and if necessary, adjusts the actual value to the target value. Be adapted.

  Although this type of finger yarn guide proved to be a very flexible yarn feeder, it is similar to the yarn guide drum, in the case of winding interruption, especially when the yarn breaks or when the controlled clearer is cut There is a drawback that there is always a risk that the upper thread connected to the thread will not be rolled up in an orderly package. That is, in the known yarn supply system, the free yarn end falls to the side of the end face of the traverse package, and in this case it can no longer be received by the yarn suction nozzle at the winding point or it is no longer orderly received. There is always the danger of not being able to.

  Therefore, in the past, for example, only when the yarn is traversed in the middle of the package by the yarn guide drum, the clearer cutting is delayed and executed so that the fallen yarn is avoided. A device was developed. However, such devices as described in German Offenlegungsschrift DE 40 25 696 or EP 0 631962 are known, as is known, at the time of yarn breaks which are produced completely uncontrolled. Generally not valid. That is, with this known device, in the case of yarn breakage, there continues to be a risk of falling yarn that cannot be handled by the yarn suction nozzle.

  Furthermore, European Patent Application No. 0814045 describes a winding position of a textile machine for manufacturing a traverse package. At this winding position, a yarn guide device that is defined and controllable is arranged in the region of the yarn guide drum. This known yarn guide device has two pneumatic guide arms which are pivotally supported and can be operated pneumatically. Both yarn guide arms can be turned in the middle of the package when the yarn tension is reduced, for example. In this case, the yarn guide arm that pivots inwardly guides the upper yarn coupled to the traverse package to the middle of the package, thereby preventing the fallen yarn from being generated. ing.

  However, the known device is relatively laborious in its design structure. That is, the device requires a relatively large amount of space. Therefore, in view of the limited space situation in any case in the area of the winding device of this type of winding point, the known device is the optimal solution for overcoming the problem of “falling yarn” Is not made.

  Starting from the above-mentioned known prior art, the object of the present invention is to provide a method or apparatus that can further ensure the operation of the working part of a textile machine for manufacturing a trawl package and in particular can easily avoid the occurrence of falling yarns. Is to develop.

  In order to solve this problem, according to the method of the present invention, the drive device of the yarn supply device is controlled by the winding position computer, whereby the yarn guide of the yarn supply device is immediately turned into the winding package in the case of winding interruption. The yarn end bonded to the wire is moved to a position where it is ensured that the yarn end is surely wound on the surface of the winding package.

  Furthermore, in order to solve this problem, in the device of the present invention, the yarn supply device includes a finger yarn guide provided with an electromagnetic drive device, and an angle sensor for detecting the respective position of the finger yarn guide. , A sensor device for detecting interruption of winding and a control computer, and an electromagnetic drive device, angle sensor, and sensor device are connected to the control computer, In the example, the drive for the finger yarn guide is controllable by a take-up computer, thereby ensuring that the yarn end coupled to the traverse package is wound onto the surface of the traverse package. The thread guide is positioned.

  Advantageous configurations of the device according to the invention are described in the dependent claims 1 to 4.

  In an advantageous embodiment of the invention, the yarn guide is immediately moved to an intermediate position with respect to the traverse package in the case of yarn breakage.

  In an advantageous embodiment of the invention, the yarn guide is moved to an intermediate position with respect to the traverse package immediately upon the introduction of the controlled clearer cut.

  In an advantageous embodiment of the invention, after detection of the yarn defect, until the yarn guide is positioned in a position that ensures that the yarn end coupled to the traverse package is reliably wound on the surface of the traverse package. Delay the introduction of controlled clearer cutting.

  The method according to the invention for operating a work site of a textile machine for manufacturing a traversed package according to claim 1, in particular by such a method, easily and with additional equipment in the area of the winding device There is an advantage that it is possible to avoid the occurrence of falling yarn when the winding is interrupted without becoming close to each other. That is, the immediate entry of the yarn guide into the set advantageous position ensures that no fallen yarns with removal which require manual operator intervention are not produced even when the yarn breaks.

  As described in claims 2 and 3, in this case, the yarn guide is immediately in the intermediate position relative to the winding package not only at the occurrence of an unexpected yarn break but also at the introduction of a controlled clearer cut. It has been found that the method steps to be run are advantageous. That is, when winding is interrupted, the traverse stroke of the yarn guide is immediately stopped in the middle of the package or the direction of the traverse stroke is immediately changed toward the middle of the package, and then the yarn guide is stopped there. This very quick and immediate positioning of the yarn guide in the middle of the package ensures that the upper yarn always rolls up on the surface of the traverse package after interruption of winding and can then be received again without problems by the yarn suction nozzle. Is done.

  In an alternative method step according to claim 4, in the event of a yarn defect, a controlled clearer cutting is ensured until the finger yarn guide is ensured to be located in a set position, i.e. in the middle of the package. It has been proposed that the introduction of In such cases, when the yarn clearer detects a yarn defect, such as a narrow or thick spot, the thread guide is first positioned in an orderly manner by the drive, and only then will the necessary clearer cut occur. It is done.

  As described in claim 5, the device for carrying out the method according to the invention is mainly for detecting a finger yarn guide loaded by an electromagnetic drive and the respective position of this yarn guide finger. Angle sensor, a yarn clearer for detecting winding interruption, and a control computer, for example, a winding point computer. In this case, not only the electromagnetic drive device for the finger yarn guide but also the angle sensor and the yarn clearer are connected to the control computer via a control line or a signal line.

  In order to be able to carry out the method according to the invention, the above-mentioned components are necessary for orderly operation of the winding site and thus constitute any existing components anyway. The additional effort required for this is mainly reduced by a slight hardware compensation of the control computer and a corresponding programming of the control computer. In other words, the effort required to implement the method according to the present invention is limited to a narrow range in terms of hardware and software.

  In the following, embodiments of the invention will be described in detail with reference to the drawings.

  FIG. 1 schematically shows a side view of a textile machine 1 for producing a twill winding package, in the example shown, one winding location 2 of a so-called “automatic winding winder”.

  As is known, such an automatic traverse winder 1 has a large number of such winding points 2 between its end frames (not shown). These winding points 2 are also known and will not be described in detail. However, the spinning cup 3 produced by the ring spinning machine installed in the front is rewound to form a large volume twill package 5. Is done. After completion of the traversing package 5, it is handed over to a machine-long traverse package transporting device 7 by a service unit (not shown), for example, a traversing package changer, and a package loading station arranged on the machine end side or the like. Transported to things.

  Furthermore, such automatic traverse winders 1 often have a logistic device in the form of a bobbin / winding tube transfer system 6. In the bobbin / winding tube conveyance system 6, the spinning cup 3 or the empty tube circulates on the conveyance plate 11. Of the bobbin / winding tube transport system 6, FIG. 1 shows only a cup supply section 24, a reversible storage section 25, a lateral transport section 26 leading to the winding location 2, and a winding pipe return section 27.

  The individual winding points 2 are only shown schematically because they are known, but each has different devices. These devices guarantee an orderly operation of this type of work site. One of these devices is, for example, a winding device indicated by reference numeral 4. The winding device 4 includes a package frame 8 that is movably supported around a turning shaft 12.

  In the case shown, the traverse package 5 is placed on the drive roller 9 on its surface 31 during the winding process and is entrained by this drive roller 9 via a frictional connection.

  However, in an alternative configuration, the traversing package may be driven via a drive device with adjustable rotational speed, preferably an electronically commutable DC motor. This driving device is arranged directly in the package frame 8 or is incorporated in the package frame 8.

  The yarn 16 is traversed by the yarn feeder 10 during the winding process. Such a thread supply device 10, which is only schematically shown in FIG. 1, has a thread guide 13 formed in a finger shape. The yarn guide 13 is loaded by an electromechanical drive device 14 and traverses the yarn 16 between the both end surfaces 32 of the traverse package 5 as shown in FIG.

  As is further apparent from FIG. 2, the drive device 14 has a motor shaft 33. A thread guide 13 formed in a finger shape is disposed on the motor shaft 33 so as not to be relatively rotatable. An angle sensor 17 is assembled on the side of the drive 14 opposite the thread guide 13, preferably protected under a removable cover cap. The structure of this angle sensor 17 is described in detail in DE 10354585.

  Further, the winding point 2 is obtained by the yarn clearer 22 connected to the winding point computer 28 via the signal line 29 and the winding point computer 28 via the line 30 arranged in the region of the yarn clearer 22. And a thread breaker 23 that can be controlled. Furthermore, in an advantageous configuration, a yarn tension sensor 20 is provided. The yarn tension sensor 20 is connected to a winding point computer 28 via a signal line 21.

Process of the method according to the invention:
As shown in FIG. 2, during regular winding operation, the yarn 16 is unwound from the spinning cup 3 that is positioned on the unwinding position in the region of the transverse conveying section 26 that is arranged on the conveying plate 11. It is wound up on the volume winding package 5. This traverse package 5 is rotatably held between the support arms of the package frame 8 during the winding process. In this case, the traverse package 5 is placed on the driving roller 9 on the surface 31 thereof. The drive roller 9 is defined and can be driven by an electromagnetic drive device 34 connected to a winding point computer 28 via a control line 19 and entrains the traverse package in a frictional manner.

  The yarn 16 crosses at least one yarn clearer 22 and the yarn cutting device 23 on the way to the traverse package 5. The running yarn 16 monitored for yarn defects by the yarn clearer 22 generates a particularly dynamic yarn running signal at the yarn clearer 22. This yarn traveling signal is transmitted to the winding point computer 28 via the signal line 29. If the dynamic yarn traveling signal is not generated based on, for example, yarn breakage, the winding point computer 28 that is always informed about the current position of the yarn guide finger via the connected angle sensor 17 is used for the control line 15. The finger yarn guide 13 is controlled as quickly as possible to a position M located in the middle of the traverse package. That is, the finger yarn guide 13 is already positioned at the position M when the upper yarn is wound up on the traverse winding package 5. Due to the quick positioning of the yarn guide finger, the yarn end of the upper yarn connected to the traverse package 5 is always located in a region that can be reached by the yarn suction nozzle 35 at the winding point 2 even after yarn breakage. Can be ensured.

  Therefore, the yarn suction nozzle 35 can receive the upper yarn from the surface of the traverse package 5 without any problem and can transfer it to the yarn splicing device 36. In this yarn splicing device 36, the yarn end of the upper yarn is coupled to the yarn end of the lower yarn supplied by the gripper pipe 37 unique to the winding part.

  After splicing the upper or lower yarn ends, the regular winding process is continued.

It is a figure which shows roughly the winding location of the textile machine which manufactures a traverse winding package provided with the traverse winding package driven by the separate motor in a surrounding surface, and the separate yarn guide driven by an individual motor. 1 is a front view of a winding point of a textile machine for producing a twill package, equipped with the equipment required to carry out the method according to the invention.
