Description

  The present invention is a brazing apparatus for a textile machine for manufacturing a trawl bobbin, which comprises a bearing shaft connected to a drive device, and is relatively unrotatable (that is, rotates together) with the bearing shaft. However, the present invention relates to a type in which a brazing member is supported so as to be axially slidable and is rotatable in a stationary casing.

  Brazing apparatuses for producing a trambo bobbin are conventionally known and many are described in the patent literature. This type of brazing device is primarily used to reduce the friction value of the yarn. That is, paraffin particles are applied to the yarn while it is rewound from a small volume spinning cup to a large volume traverse bobbin (this is done, for example, by an automatic traverse machine). This paraffin particle improves the running and sliding properties of the yarn. This is particularly important during subsequent processing processes such as weaving and knitting processes.

  In order to obtain as uniform wear of the brazing member as possible, in known brazing devices, the brazing member is rotated slowly about its central axis, while at the same time the traveling yarn is on the end face side of the brazing body. Touch lightly. In this known brazing device, the brazing body is relatively non-rotatable on the driveable support shaft, but is supported so as to be slidable in the axial direction, and is generally used for the yarn traveling by the spring member. Loaded towards.

  In this case, the working position of the brazing body can be given in advance by adjustable stroke limiting means. This working position defines the amount of wax (paraffin) to be brazed.

  This known brazing device has the disadvantage that the brazing device is relatively dirty. That is, paraffin particles that are drawn from the brazing member by the running yarn and often adhere poorly to the yarn will contaminate the brazing device in a relatively short time, and under the brazing device based on gravity. The component parts arranged in the are particularly strongly soiled.

  Therefore, a rotating brazing member is placed under the stationary cover, or at least a receiving tray is incorporated under the brazing member, in which paraffin particles are rubbed off and are not entrained by the running yarn. Collected.

  A brazing device with such a receiving tray arranged under a rotatable brazing member is described, for example, in DE 43 38 453 A1. The known brazing device further has a cover which is divided in two on the front side, which prevents the rubbed paraffin particles from falling down. In practice, it has been found that using a receptacle for paraffin particles falling downwards is not very effective. This is because, over time, the collected paraffin particles significantly contaminate the entire brazing apparatus, and as a result, the functionality of the brazing apparatus is hindered. Moreover, such a receiving container also impedes the possibility of accessing (accessing) the machine part located under the receiving container.

  A comparable device is also described in German Offenlegungsschrift 10342009. In this known brazing device, the brazing member rotates within a stationary tubular cover. The cover whose front is closed by a cover member that is pivotally supported has an upper through-opening and a lower through-opening for the traveling yarn. In the cover member, a receiving part is incorporated for paraffin particles that do not adhere to the traveling yarn and fall down.

Even in this known brazing device, it cannot be prevented that many paraffin particles are collected in the receiving part of the cover member over time and significantly disturb the functionality of the brazing device. Moreover, in this known brazing device, there is a risk that the rotating brazing member rides on the stationary covering, which causes the brazing member to wear significantly and thus over time, the brazing device becomes very dirty. It will be. Moreover, such collected and often agglomerated paraffin particles are dragged uncontrollably by the running yarn, thereby significantly fouling the yarn traversing device connected downstream from the yarn path.
German Patent Publication No. 4338453 German Patent Publication No. 10342009

  Therefore, the object of the present invention is to improve the brazing device of the type described at the beginning, so that the undesired rubbing of paraffin particles is sufficiently avoided, and the rubbing is carried out uncontrollably by the running yarn. It is to provide such that no paraffin is collected in the area of the brazing apparatus.

  According to the present invention that solves this problem, the wax container is coupled to the support shaft so as not to be relatively rotatable, and the brazing member is disposed in the wax container. A wax container together with the member is configured to be rotatable within a stationary casing of the brazing device.

  Advantageous embodiments of the invention are described in the dependent claims.

  In accordance with the present invention, a relatively sensitive brazing member and a stationary casing surrounding the brazing member by means of a brazing member arranged axially slidable but not relatively movable in a rotatable wax container, There is no direct relative movement between them that causes inconvenient paraffin particle scraping.

  In other words, according to the present invention, the brazing member is disposed in a rotatable dedicated wax container while being protected against inadvertent scraping and dust and floating fibers. Since the wax container can be easily replaced together with the brazing member whenever necessary, according to the configuration of the present invention, it is possible to replace the wax container with a new one without any problem.

  In this case, according to an advantageous embodiment, the brazing member is slidably arranged in the axial direction on the bearing addition part of the wax container so as to be slidable in the axial direction, and is connected to the wax container via the entraining disk. They are coupled so that they cannot rotate relative to each other (claim 2). According to such a configuration, only a relatively small axial relative movement is performed between the brazing member and the wax container surrounding the brazing member.

  This very slow axial sliding movement of the brazing member is effected by paraffin rubbing of the yarn running during the rewinding process.

  According to an advantageous embodiment as claimed in claim 3, an annular gap is provided between the outer peripheral surface of the wax container and the inner wall of the stationary casing. Such an annular gap not only ensures a perfect and smooth rotational movement of the wax container within the stationary casing of the brazing device, but also causes the brazing device to be periodically introduced by, for example, a blow device according to claim 4. It can also be washed.

  As described in claim 4, the blow nozzle device mainly comprises a blow nozzle device disposed in the bottom region of the stationary casing, and the blow nozzle device has a solenoid valve that can be controlled in a predetermined manner. Via an overpressure source. In this case, the plurality of blow nozzles arranged in an annular shape are directed to the annular gap so that dirt existing in some cases can be blown away without any problem. In other words, the arrangement of the blow nozzle in the area of the annular gap prevents dirt particles or dust particles from accumulating in the annular gap and does not adversely affect the function of the brazing device over time. .

  According to an advantageous embodiment as claimed in claim 5, a stroke limiting means is provided for limiting the axial sliding movement of the brazing member in the brazing device. This stroke limiting means is fixed to a turning arm arranged on the front side of the stationary casing of the brazing device, and this turning arm is closed during the winding operation. That is, it is positioned at the operating position.

  In order to replace the new brazing member, the swivel arm is swiveled from the operating position to the loading position in a simple manner, where it can be replaced with a new brazing member without problems or a new one. It can be replaced with a wax container provided with a pulling member.

  In other words, in the operating position, the swivel arm provided with the stroke limiting means can be positioned in a predetermined working position where the brazing member is different, whereas the brazing device is freely accessible in the swivel arm loading position ( Approach).

  According to an advantageous embodiment as claimed in claim 6, the swivel arm can be locked in the operating position by a permanent magnet device. For this purpose, the swivel arm is advantageously made of a ferromagnetic material, for example steel, whereas the casing surrounding the brazing member is made of plastic, for example, in which a permanent magnet is placed. The element is inserted.

  Such a permanent magnet device is not only inexpensive, but also has a very high function reliability. Moreover, such permanent magnet devices require almost no maintenance.

  As described in claims 7 and 8, in a preferred embodiment, the rotational movement of the wax container is effected by means of an individual drive device of the electric motor type. That is, the support shaft on which the wax container is disposed so as not to be relatively rotatable (that is, so as to rotate together) is connected to a motor shaft of an individual drive device that can be controlled in a predetermined manner.

  In this way, the wax container can be adjusted individually, particularly in relation to its rotational speed.

  In this case, as described in claim 8, the individual drive device is advantageously configured as a step motor. Such a step motor is a driving means that is inexpensive and requires almost no maintenance.

  The present invention will be described in detail below with reference to illustrated embodiments.

FIG. 2 is an enlarged cross-sectional side view of a brazing device according to the present invention.

  FIG. 1 shows a schematic side view of a working machine 2 of a textile machine for manufacturing a traverse bobbin, in the illustrated embodiment a so-called automatic traverse winding machine 1. Such an automatic traverse winding machine 1 has a large number of working sections 2 arranged in parallel in a row of the same type, and in these working sections 2, a spinning cup 3 having a relatively small amount of yarn volume, It is rewound onto a large-volume Ayanaki bobbin 5. Since this is well-known, detailed description is omitted.

  The running yarn 16 is monitored during winding up for yarn defects that may need to be removed, as is known. Moreover, the yarn 16 is brazed during the rewinding process. That is, the yarn 16 is guided through the brazing device 19, which reduces the friction value of the yarn 16. In other words, the running characteristics and the sliding characteristics of the yarn 16 are remarkably improved by performing the brazing as described above.

  A corresponding brazing device 19 will be described in detail later with reference to FIG.

  The traverse bobbin 5 is handed over to a traverse bobbin transport device 7 provided over the length of the textile machine by a service device (not shown) that automatically operates after completion, and ends the textile machine. To a bobbin loading station or similar.

  Further, as shown in FIG. 1, such an automatic traversing machine 1 is often provided with a bobbin and a winding tube transfer system 6, and in the bobbin and the winding tube transfer system 6, such a transfer disk is provided. 11, the spinning cup 3 or the empty pipe circulates. Of such a bobbin and winding tube transfer system 6, FIG. 1 shows one of a cup supply section 24, a storage section 25 that can be driven in reverse, and a lateral transfer section 26 that leads to the working unit 2 (winding unit). Only the winding return guide section 27 is shown.

  Further, each working unit 2 has various devices for regularly driving a plurality of working units of this type. Since such devices are known, they are only schematically shown in FIG.

  Such a known device is, for example, a winding device 4 having a bobbin frame 8 movably supported around a pivot shaft 12. According to the illustrated embodiment, the traverse bobbin 5 has its outer peripheral surface resting on the drive drum 9 during the winding process and is connected via a frictional connection (constraint by friction) by this individually driven motor-driven drive drum 9. Taken away.

  A corresponding drive device connected to the working computer via the control line 35 is indicated by 33.

  A yarn traversing device 10 is provided for traversing the yarn 16 during the winding process. The yarn traversing device 10, which is likewise known and only schematically shown in FIG. 1, has a yarn shift lever configured in a finger shape via a yarn guide 13. The yarn shift lever loaded by the electromechanical driving device 4 traverses the yarn 16 between both end surfaces of the traverse bobbin 5. Similarly, the drive unit 14 for the yarn guide 13 is connected to the working unit computer 28 via the control line 15.

  As described above, the working unit 2 of such an automatic traversing machine 1 has a brazing device 19 in the yarn path immediately before the yarn traversing device 10, and this brazing device 19 is used for the yarn 16 during the rewinding process. Nylon (paraffin) can be applied.

  As shown in the figure, the individual driving device 34 of the brazing device 19 is connected to the working unit computer 28 via a control line 57.

  FIG. 2 shows a cross-sectional view of a brazing device 19 according to the invention. The brazing device 19 has a stationary casing 23, which is fixed to the spinning section casing 60 via a holder (not shown).

  A step motor 34 is fixed to the stationary casing 23, and the step motor 34 is connected to the working unit computer 28 via a control line 57. A wax container 41 is supported on the motor shaft 28 of the step motor 34 through a bearing addition portion 36 so as not to be relatively rotatable (that is, so as to rotate together). A waxing member 18 is supported on the bearing addition portion 36 in the wax container 41 so as not to be relatively movable but slidable in the axial direction.

  A swivel arm 21 is pivotally attached (hinge-coupled) to the front side of the stationary casing 23. The swivel arm can swivel between an operating position and a loading position, and is moved by a permanent magnet device 22 in the operating position. It is locked. In this case, the permanent magnet device 22 includes a permanent magnet element 29 fitted in the casing 23 and a swivel arm 21 made of a ferromagnetic material. The swivel arm 21 has a stroke restricting means 17, which can be slid in the axial direction in the wax container 41 through the angular position of the stroke restricting means 17, but is supported so as not to be relatively rotatable. Different working positions can be adjusted.

  In this case, as shown in FIG. 2, the brazing member 18 cannot rotate relative to the bearing addition portion 36 of the wax container 41 via an entraining disk 37 having a pin 38 or the like. And by extension, the wax container 41 is also coupled so as not to be relatively rotatable. The axial sliding of the brazing member 18 in the bearing load portion 36 is performed via a spring element. The spring element 39 is supported by the pressure plate 40 and loads the entrainment disk 37 in the direction R. In other words, the brazing member 18 is slid in the direction R in the wax container 41 until the front side 24 of the brazing member 18 comes into contact with the stroke limiting means 17.

  The stationary casing 23 has a blow nozzle 54 at its bottom region 45, and this blow nozzle 54 is connected to an overpressure source 55 via a solenoid valve 56 that can be controlled in a predetermined manner. In other words, the plurality of blow nozzles arranged in an annular shape can be quickly blown out without any problem of contamination in the annular gap 53 that exists in some cases, and the outer periphery of the wax container 41 and the inner wall 51 of the casing 23. It is directed to an annular gap 53 formed between the surface 50.
