Description

  The present invention provides a traverse package having a paraffin body supported so as to be axially movable in a bearing housing, wherein the front surface of the paraffin body coincides with a running yarn traversed during the winding process. The present invention relates to a paraffin coating apparatus for a textile machine to be manufactured.

  Paraffin coating apparatuses for textile machines for producing traversed packages have been known for a long time in the textile machine industry, and a number of embodiments are described in detail in the patent literature.

  Such a paraffin applicator is primarily used to reduce the coefficient of friction of the yarn, as is known. That is, paraffin particles are applied to the yarn to improve its running and sliding properties during rewinding from a small volume spinning cup to a large volume traverse package, for example in a traverse package autowinder. . This is particularly significant during subsequent processing processes, for example during warp knitting or weft knitting.

  For example, in a paraffin coating device known from patent document 1 or patent document 2, the paraffin body is rotated and pressed around its central longitudinal axis in order to achieve as uniform a wear of the paraffin body as possible. The device is pressed against the traveling yarn. At this time, the end surface of the paraffin body comes into contact with the running and traversed yarn and applies paraffin to the yarn.

  In such a paraffin coating device, various structures can be used as a pressing device for moving a paraffin body supported by a driveable bearing shaft so as to be axially movable although it cannot rotate. . For example, Patent Document 1 discloses a coil spring, and this coil spring is disposed on the bearing shaft behind the paraffin body and presses the paraffin body in the axial direction toward the traveling yarn.

  A comparable pressing device is also described in Patent Document 2. In this known paraffin coating apparatus, the paraffin body is pressed by an additional pressing lever, and the pressing lever itself is subjected to a spring action of a pre-constricted flexure spring. Even in this known configuration, the paraffin body is always kept in contact with the traveling yarn.

  In these known paraffin applicators, the working position of the paraffin body is further preset by adjustable distance limiting means that can determine the thread wrap angle and thus the amount of paraffin applied.

  However, for these known paraffin applicators widely used in practice, these paraffin applicators run paraffin to ensure that the paraffin is adequately applied to the yarn under all circumstances. The disadvantage is that the yarn is often provided in excess. In other words, in known paraffin coating apparatuses, the operation is often carried out with a thread winding angle that is too large and consequently with a paraffin coating amount that is too large.

  Paraffin particles separated from the paraffin body by the yarn running while traversing often do not adhere firmly to the yarn, so such a paraffin coating device not only increases the amount of paraffin consumption, but is already relatively short. After a lapse of time, the paraffin coating apparatus is soiled, and the working member disposed under the paraffin coating apparatus is severely soiled due to gravity.

  Therefore, in connection with such a paraffin coating apparatus, in the past, a rotatable paraffin body has already been placed inside a stationary cover, or at least under the paraffin body, a collection trough has been installed, and this trapping has been carried out. It has been proposed to be able to collect separated paraffin particles that have not been applied to the running yarn in the collecting trough.

  For example, such a paraffin coating apparatus provided with a collection container for falling paraffin particles described in Patent Document 3, Patent Document 4 and Patent Document 5 is used in a practical application, particularly in a winding roll auto winder. Based on very limited space conditions in the working part, it has not proved to be very good. Moreover, such a paraffin coating apparatus still has the disadvantage that the consumption of paraffin is unnecessarily high.

  Furthermore, these known paraffin applicators require a new and time-consuming adjustment of the paraffin body stopper when changing the yarn lot, where it is desirable to change the paraffin application condition based on the new yarn material. There is a drawback of being. That is, in a known paraffin coating apparatus, each change in the amount of paraffin applied always requires a change in the thread winding angle in the paraffin body, and thus a correction of the position of the paraffin body stopper.

Swiss Patent Application No. 706608 German Patent Application No. 4010469 German Patent Application No. 4338453 German Patent Application Publication No. 10342009 German Patent Application No. 102005028751

  Starting from the prior art described above, the object of the present invention is to avoid, on the one hand, inadvertent paraffin peeling or paraffin wear during the winding process, and on the other hand to always optimally apply paraffin to the running yarn. It is to provide a paraffin coating apparatus that can be used.

  In order to solve this problem, in the paraffin coating apparatus according to the present invention, the paraffin-coated annular body is guided to the front region of the bearing housing of the paraffin coating apparatus so that the thread to be traversed is guided at a fixed basic winding angle. In addition, a feeding device is provided which is positioned and can be adjusted and fixed and moved axially toward the paraffin-coated annular body.

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

  The configuration of the paraffin coating apparatus according to the present invention has the following advantages. That is, in the paraffin coating device of the present invention, the use of the feeding device not only guarantees an accurate supply suitable for the paraffin body at any time, but also the paraffin coating on the front side of the bearing housing. The annular body also ensures that the yarn is guided with sufficient crimping force in the area of the paraffin applicator, which has a very positive effect on the paraffin application performed on the yarn. That is, the feeding device helps to apply a relatively sensitive paraffin body to the yarn traveling at a constant relatively small pressure at all times during the whole winding process, and the winding angle of the traveling yarn at this time is the paraffin-coated annular body. Is preset in advance.

  With such an arrangement, on the one hand the yarn is optimally paraffinized and on the other hand the paraffin wear in the paraffin body is also minimized.

  Furthermore, the preferred configuration of the paraffin-coated annular body arranged for the paraffin body on the front side of the bearing housing prevents most of the paraffin particles applied to the traveling thread from immediately peeling off from the thread again.

  In a preferred embodiment, the paraffin-coated annular body has a thread guide surface that is inclined outward in a slope shape, and is provided with two side stoppers that limit the traversing area of the traveling thread. ing.

  In the context of overfeeding of the paraffin applicator (Ueberlaufen) in the context of a correspondingly adapted feed of the paraffin applicator by means of the thread guide surface which is inclined outwardly in a slanted manner on the paraffin application ring The yarn wrap angle remains the same and the yarn is pressed relatively little. The two stoppers at the sides prevent the traveling thread from falling off the paraffin coated ring or paraffin body. This is because the yarn that runs by the side of the paraffin-coated annular body without being noticed is wound around the winding package without being paraffin-coated, and this must be prevented.

  In another preferred embodiment, the feeder device has a drive motor that is fixed and controllable, the drive motor rotating a threaded spindle coupled to the drive motor, at this time to the threaded spindle. Is connected to a feed carriage via a female thread element, which contains a paraffin body.

  In such an aspect, such a configuration is a compact structure that can be installed in the working unit without any problem despite the narrowed space situation, and is an apparatus that can be operated with high reliability and accuracy. There is an advantage of being. That is, the threaded spindle can be rotated very accurately with the aid of a drive motor, preferably designed as a stepping motor, so that the associated feed carriage can be accurately connected via a connected female thread element. A precise axial movement, in turn, produces an accurate feed rate of the paraffin body.

  The step motor preferably has a high number of steps, preferably at least 1600 steps. With such a step motor, it is possible to accurately move the paraffin body in the axial direction, and if necessary, the paraffin body can be operated at a very low feed rate.

  In another preferred embodiment, the feed rate of the paraffin body can be set accurately in advance in the working machine calculator and / or the central control unit of the textile machine.

  The adjustment of the paraffin body feed rate in the textile machine working unit computer and the adjustment of the paraffin body feed speed in the central control unit are based on the method of correcting the position of the paraffin body stopper, which has been conventionally performed at the time of lot exchange. Provide a great advantage. At this time, if it is necessary to simultaneously adjust a large number of working parts to a new feed speed of the paraffin body, it is possible to save a lot of time, so adjustment of the feed speed in the central control unit of the textile machine is particularly suitable. It is.

  In another preferred embodiment, the paraffin coating device is provided with a first sensor device that monitors the rotation angle of the step motor and a second sensor device that detects the actual state of the paraffin body. The first sensor device allows a very accurate monitoring of the rotation of the threaded spindle and thus a very accurate positioning of the feed carriage or the paraffin body supported on the feed carriage.

  Since the actual state of the paraffin body is always detected using the second sensor device, the necessary paraffin body can be grasped in a timely manner and replaced with a new paraffin body in a timely manner. Can do.

  Such a textile machine 1 for producing a traverse package, for example formed as a traverse package autowinder, has a number of working parts 2 of the same kind arranged in a row alongside one another. In these working sections 2, as is well known, and therefore not described in detail, a spinning cup 3 having a relatively small amount of yarn is rewound into a large volume traverse package 5.

  The yarn 16 drawn from the spinning cup 3 is, as is known, monitored for possible yarn defects during winding, and such yarn defects are optionally removed. The traveling yarn 16 is further coated with paraffin during the rewinding process. In other words, the traveling yarn 16 is guided through the paraffin coating device 19, and this paraffin coating device 19 is useful for reducing the friction coefficient of the yarn 16 and thus significantly improving the running characteristics and the sliding characteristics of the yarn 16.

  The corresponding paraffin coating device 19 according to the present invention will be described in detail later with reference to FIGS.

  The finished traverse package 5 is usually delivered to the traverse package transport device 7 over the machine length using a service unit (not shown) that operates automatically, and this traverse package transport device 7 is used. , Transported to a package charge station located on the machine end side or a similar location.

  As further schematically shown in FIG. 1, such a traversed package autowinder 1 often includes a bobbin / winding tube transfer system 6, and the bobbin / winding tube transfer system 6 includes a transfer plate 11. The spinning cup 3 or the empty tube circulates.

  In such a bobbin / winding tube transfer system 6, FIG. 1 simply includes a cup supply section 24, a reversible drive storage section 25, a lateral transfer section 26 leading to the working unit 2, and an empty pipe return section 27. It is shown.

  The individual working units 2 further have various devices that guarantee such an orderly operation of the working units 2. Such a device is likewise known per se and is therefore only schematically shown in FIG.

  One of such devices is, for example, a winding device 4, and the winding device 4 has a package frame 8 that is movably supported around a turning shaft 12.

  According to the present embodiment, the traverse package 5 held on the package frame 8 is in contact with the drive drum 9 during the winding process, and the drive drum 9 is driven by the individual motor. Rotated by friction. The associated drive connected to the working unit computer 28 by the control line 35 is indicated by reference numeral 33.

  According to the present embodiment, the yarn traversing device 10 is provided for traversing the yarn 16 traveling during the winding process. A similarly known yarn traversing device 10 which is simply shown schematically in FIG. 1 has a yarn guide 13 with, for example, a yarn traversing lever formed in the shape of a finger.

  The yarn traversing lever operated by the electromechanical driving device 14 traverses the traveling yarn 16 between both ends of the traverse winding package 5. Similarly, the driving device 14 of the yarn guide 13 is connected to the working unit computer 28 via the control line 15.

  As already described above, the working unit 2 of the traverse package auto winder 1 further includes a paraffin coating device 19 in front of the yarn traversing device 10 on the yarn running path. The applicator 19 enables the application of paraffin to the yarn 16 during the rewinding process.

  As schematically shown in FIG. 1 and particularly clearly shown in FIGS. 2 and 3, the drive unit 34 of the paraffin coating device 19 is also connected to the working unit calculator 28 via a control line 37.

  FIG. 2 is an enlarged perspective view of the paraffin coating apparatus 19 according to the present invention.

  As can be seen from the drawing, the paraffin coating device 19 fixed to the working unit housing 17 via, for example, a holding device (not shown) has a bearing housing 30, which is provided on the back side. A connection plate 18 and a front connection plate 29 are provided. A drive device 34, preferably formed as a step motor, is fixed to the connection plate 18 on the back side, for example, using a bolt 45, and this drive device 34 is connected to the working unit computer 28 via a control line 37. And / or connected to the central control unit 44 of the traverse package autowinder 1.

  As can be seen in particular in FIG. 3, a threaded spindle 20 is connected to the motor shaft of this stepping motor 34, and this threaded spindle 20 is coupled to the feed carriage 22 via a female thread element 21. In this embodiment, the feed carriage 22 supports a paraffin body 23 formed in a pin shape.

  The feed carriage 22 is supported so as to be movable in the axial direction inside the bearing housing 30 using, for example, a guide device 39 shown in a sectional view. That is, the feed carriage 22 can be moved in the axial direction by the rotation of the threaded spindle 20 in the rotational direction R, for example.

  Further, as can be seen from the drawing, a paraffin-coated annular body 31 is fixed to the connection plate 29 on the front side of the bearing housing 30 by means of bolts 46, and this paraffin-coated annular body 31 is particularly inclined (fasenartig). Has a yarn guide surface 32 (see FIG. 4). Further, the paraffin-coated annular body 31 is provided with two stoppers 36 at the side and a central supply hole 38, through which the paraffin body 23 is brought into contact with the yarn 16 traveling during the winding process. (See FIGS. 4 and 5).

  The paraffin coating apparatus 19 according to the present invention further includes a first sensor device 40 and a second sensor device 41. The first sensor device 40 arranged in the area of the rear connection plate 18 monitors the rotation angle of the stepping motor 34 or the threaded spindle 20, whereas it is arranged in the area of the front connection plate 29. The second sensor device 41 detects the actual state of the paraffin body 23 each time.

Functions of the paraffin coating apparatus according to the present invention:
When changing the lot, it is considered preferable to change the amount of paraffin applied. When changing lots, first, the machine unit 28 of the textile machine or the central control unit 44 of the traverse package auto winder 1 is selected according to the yarn material to be applied. Then, a new paraffin coating amount, i.e., the desired feed rate of the paraffin body 23 during the subsequent winding process, is entered.

  In response to this input, the drive device 34 of the paraffin application device 19 serves to always accurately position the front surface 42 of the paraffin body 23 during the winding process, in particular as shown in FIG. Light contact occurs between the front surface 42 and the traveling yarn 16, and the yarn 16 is rubbed while reciprocating in the traverse direction on the yarn guide surface 32 of the paraffin-coated annular body 31.

The feeding speed of the paraffin body 23 is selected as follows. That is, in this case, the yarn running path is not adversely affected, and the yarn 16 is set in advance during the whole winding process and when the yarn 16 rides on the paraffin-coated annular body 31 and descends or separates from the paraffin-coated annular body 31. The fixed basic winding angles β ₁ and β ₂ are maintained. That is, the yarn guide surface 32 of the paraffin-coated annular body 31 that is generated when the thread 16 is loaded on the paraffin-coated annular body 31 and the run-out eye disposed on the upstream side (as viewed in the yarn traveling direction) of the paraffin coating device 19. 43 and the basic winding angle beta ₂ which is set in advance by, occurs during drop of the yarn 16 from a paraffin coating annular body 31, the guide surface 32 of the paraffin coating annulus 31, in advance by the position of the traverse triangle yarn The set basic wrap angle β ₁ remains unchanged during the entire winding process.
