Definitions

  • the invention relates to a waxing device according to the preamble of claim 1.
  • Paraffining devices have long been known in the context of cheese-making textile machines and described in detail in the patent literature.
  • paraffining devices are used in cheese-making textile machines mainly to reduce the coefficient of friction of a yarn. That is, in open-end spinning machines, for example, the freshly prepared yarn, before it is wound into a cheese, applied paraffin particles, which improve the running and sliding properties of the yarn, which has a positive effect especially in subsequent processing, such as knitting and knitting ,
  • the paraffin body In order to achieve the most uniform possible wear of the paraffin body in such paraffining facilities, the paraffin body is usually slowly rotated about its central longitudinal axis, wherein the current thread at the same time easily applied to the front side of the paraffin body.
  • the paraffin body is rotationally fixed for this purpose, but mounted axially displaceably on a drivable receiving shaft and is pressed by a spring element against Wegbegrenzungsstoff that dictate the working position of the paraffin body.
  • paraffining devices With regard to the drive of the take-up shaft of such paraffining devices, various embodiments are used. For example, it is known to drive the take-up shafts of the machine-side paraffining devices, like the other functional elements of the workstations of such textile machines, over machine-length drive shafts which are each acted upon by an electric motor arranged in the end frame of the textile machine. Paraffining devices, which are acted upon directly or indirectly by a machine-length drive shaft, are for example in the DE 195 39 099 A1 , in the EP 0 071 582 A1 or im Manual "AUTOCORO" by Schlafhorst, page 1.4.15 described.
  • the present invention seeks to provide a paraffining device, which is both favorable in terms of their production costs, as well as designed so that the arranged in a job site paraffining device, if necessary, together with the Garn Strukturs- and / or the winding devices of the relevant job, can be easily removed.
  • the paraffining device according to the invention with a telescopically designed drive shaft which has a first shaft piece with a coupling device arranged at the end and a second shaft piece with a coupling element arranged at the end, wherein the coupling device and the coupling element are each designed so that they can correspond with one another, has the advantage in that the drive shafts are adjacent Paraffinier Vietnameseen can be easily joined together to form a continuous drive train, which can be easily separated in linearfall but also. That is, with such trained paraffining can be realized in a simple and cost-effective manner, a continuous drive train, which ensures a safe drive multiple Paraffinier Nur during spinning operation and is very reliable and almost maintenance-free.
  • the paraffining device according to the invention can also, if necessary, even with the textile machine running, preferably together with their associated work place housing and also arranged in the work place housing and then shut off Garn avoirs- and winding facilities of the relevant job to be replaced.
  • At the paraffining facilities only two shaft pieces of the continuous drive train in the sense of "shorten the drive shaft" must be moved in the course of such a removal or installation of a workstation housing. That is, the first shaft of the telescopic drive shaft of the respective paraffining device and the first shaft of the paraffining device of the adjacent work site must be pulled out of their adjacent second shaft pieces.
  • the workstation housing in question can then be easily removed, preferably after releasing some easily releasable fasteners on the workstation housing.
  • the resulting gap in the drive train can either be closed by the installation of a new complete workstation housing, or it is simply first a separate, telescopic drive shaft clipped into the gap of the drive train and closed in this way the drive train again.
  • drive shafts of adjacent paraffining devices can be connected via the coupling device of a first shaft piece and the coupling element of a second shaft piece, wherein a coupling device with a coupling element in the assembled state in each case forms a non-rotatable, if necessary, manually easily releasable clip connection. That is, via the two coupling parts, the first and second shaft pieces of the drive shafts of adjacent paraffining devices can be easily connected to a continuous drive train, on the one hand during the spinning operation for a safe drive of the paraffining devices on the other hand, if necessary, but also easily be separated again. The operator does not need special tools to disengage and remove a paraffin device that is turned on in a continuous powertrain from the driveline.
  • the second shaft piece is rotatably mounted, but fixed in the axial direction, via an intermediate shaft piece in the housing of the waxing device.
  • Such a design of the second shaft piece and the intermediate shaft piece facilitates the production of a telescopic drive shaft, in particular, if an axially displaceable mounting of the first shaft piece of the drive shaft is provided in the intermediate shaft piece considerably.
  • the first shaft piece is rotationally fixed, but axially displaceable, mounted in a bearing recess of the intermediate shaft piece. That is, by an advantageous embodiment of the first shaft piece is provided in conjunction with a corresponding advantageous embodiment of a bearing recess in the intermediate shaft piece that on the one hand a secure rotationally fixed connection of the shaft pieces is ensured during operation and on the other hand, if necessary, easily at any time a change easily the length of the drive shaft is possible.
  • the section drive for preferably twelve paraffining devices is formed, for example, as a stepping motor with associated stepper motor gear, wherein the stepping motor gear has a connection means for the drive train.
  • the connection means may correspond in its structural design to the structure of a coupling element, as it is known from a second shaft piece. This means that a coupling device of a first shaft section of a telescopic drive shaft of a paraffining device can be connected to the stepper motor gearbox at any time without problems, which then forms the first section of a drive train of a machine section.
  • the present invention should not be limited to the use of two drives per machine section or two drive trains, each of which has exactly the length of a machine section. It is also conceivable to use more than two drives per machine section or to choose a drive train that is longer than a machine section.
  • each first shaft of the telescopic drive shaft of a paraffining device is equipped with a handle attachment, which allows easy positioning of the first shaft piece. That is, the handle lug facilitates an operator in case of need, the loosening or making a clip connection between an axially fixed second shaft piece and an axially displaceably mounted first shaft piece.
  • the handle approach is particularly advantageous if the first shaft piece, which is not always completely avoid something contaminated by paraffin abrasion and thus something has become smooth.
  • the telekopierbare drive shaft is made of a modern plastic.
  • Such modern plastics are durable and relatively insensitive materials that are also relatively inexpensive.
