Definitions

  • the invention relates to a drafting system for spinning units according to the preamble of claim 1.
  • the fiber material to be spun is usually fed to the spinning units in the form of fiber slivers or rovings, which pass through a drafting system in front of the spinning unit.
  • the rollers or cylinders of the drafting systems may undesirably wind waste fibers during the spinning operation. Dissolves this the drafting roller adhering fiber material and gets into the Luntenlaufbahn, which is also called track, this can lead to unwanted knots or thickening in the fuse and in consequence to unacceptable errors in the yarn. It is therefore customary to remove the waste fibers by means of cleaning rollers of the drafting rollers again.
  • the cleaning rollers are rotated by the work rolls of the drafting by friction action in rotation and are covered with a plaster coating.
  • DE 44 29 671 Cl shows a Oberwalzenaniarm with an alternative embodiment of a holder for the top rollers.
  • the top rollers are mounted in so-called handlebars, which are held longitudinally displaceable and lockable in Oberwalzenaniarm.
  • the application of the load on the top rollers is carried out by a hose-like pressure body, which is supplied from a compressed air source of compressed air. All handlebars can be acted upon by printing plates with a pressure load.
  • the holder shown serves solely for the storage of the top rollers.
  • the generic EP 0 344 944 AI describes a drafting system, in which the upper roller carrying and loading arm has a plurality of upper rollers with associated cleaning rollers. In operating position, the upper rollers are delivered to the lower rollers and loaded.
  • the top roller carrying and loading arm holds cleaning rollers on each side, each of which overlaps only one track. Top rollers and cleaning rollers each have separate brackets.
  • the upper rollers are mounted on support arms which are mounted in the interior of the U-shaped, downwardly open upper roller support and -belastungsarmes about horizontal pivot axes. Such a pivot bearing requires considerable space in the upper roller carrying and loading arm.
  • the installation of pneumatic pressure bodies in the upper roller support and loading arm, with which the top rollers in a simple way and evenly and again can be relieved, is not or only partially possible.
  • the axes of the cleaning rollers are inserted into a holder which is adjustably mounted on top of the upper roller carrying and loading arm in the longitudinal direction of the upper roller carrying and loading arm.
  • the support member is a common support for top rollers and clearer rollers, which is stable and well suited for cost-effective mass production.
  • the number of components to be manufactured and assembled for the holder is reduced.
  • In the joint storage of each of which cooperating upper rollers and cleaning rollers of the drafting system in a mounting element in each case only one adjusting operation is required in the case of a field width change.
  • the top roller associated with the put wandered with when the field widths must be changed by moving the Oberwal ze for a new spinning process.
  • the manual effort in field width changes and the associated downtime can be reduced in this way.
  • An end of the axis of Putzwal zen is formed in an advantageous embodiment to a comprehensive federal government holding device.
  • the holding device engages behind the slotted guide of the support element.
  • top roller and machine frame With an electrically conductive connection between top roller and machine frame according to claim 4, an electrostatic charge of the top roller is avoided. A Such electrostatic charging can lead to malfunctions and yarn defects.
  • the support element according to the invention offers the possibility to choose a production of sheet steel.
  • a support member made of sheet steel can be produced quickly and inexpensively by manufacturing steps such as cutting and bending and is well suited to the function-induced applied loads.
  • the bracket made of sheet steel has a relatively low weight and takes up little space.
  • the adjustment of the rollers serving displacement of the support member in the longitudinal direction of the top roller Trag- and -belastungsarms can be easily and continuously performed.
  • the support member according to claim 7 makes it possible to execute a handlebar supporting the axis of the top rollers so that it has only a relatively small width and inexpensive consists of elastic plastic, without having to accept the aforementioned disadvantages.
  • FIG. 1 is a simplified perspective view of a top roller support and -belastungsarms with an example serving as a support member and top and clearer rollers,
  • Fig. 3 is a simplified perspective view of the
  • the upper roller carrying and loading arm 1 illustrated in FIG. 1 is pivotably mounted about the axis 2 in an upper end position and a lower spinning operating position. Such storage for a Oberwalzenträgarm is shown for example in DE 44 29 671 Cl.
  • the upper roller carrying and loading arm 1 is substantially U-shaped and open at the bottom.
  • a top roller 3, 4 and a cooperating with this cleaning roller 5, 6 are arranged on each side of the upper roller carrying and loading arm 1, a top roller 3, 4 and a cooperating with this cleaning roller 5, 6 are arranged.
  • the upper rollers 3, 4 are in spinning operating position of the upper roller support and loading arm 1 against associated, not shown for reasons of simplification lower rollers pressed, as shown for example in EP 0 344 944 AI.
  • Both the upper rollers 3, 4, which are mounted on an axle 37, and the cleaning rollers 5, 6 are held by a common support member 7.
  • the support member 7 is adjustable in the longitudinal direction of the upper roller support and loading arm 1, after a fixation, not shown here, which can act non-positively or positively, has been solved. For an adjustment of the position of the support member 7 is possible with a new field width adjustment. Further required for the stretching process top rollers with the associated cleaning rollers can be easily arranged on the upper roller support and loading arm by other support elements are placed and fixed to the top roller support and load arm 1.
  • the main body 27 of the support member 7 is shown separately and compared to the figure 1 enlarged.
  • the main body 27 of the support member 7 is symmetrical and made of steel.

  • the axis 25 of the cleaning roller 5 is inserted into the guide 16 of the support member 7.
  • Figure 3 shows the position occupied by the cleaning roller 6 when it rests on the top roller 3 by its own weight during the spinning operation. If the top roller carrying and loading arm 1 is pivoted to the upper end position and thereby the cleaning rollers 5, 6 lifted from the top rollers 3, 4, the cleaning rollers 5, 6 are no longer supported by the top rollers 3, 4, and the axes of Cleaning rollers 5, 6 slide in the slide guides 16, 17 down until they resting on the support plates 22, 23.

Abstract

Système d'étirage pour unités de filature, qui comporte au moins un bras de support et de charge (1) de cylindres supérieurs. Des cylindres nettoyeurs (5, 6), ajustables transversalement par rapport à leur axe de rotation, sont montés dans un élément de retenue (7) sur le bras de support et de charge (1) de cylindres supérieurs de manière telle que pendant le processus de filature, ils reposent sur le cylindre supérieur (3, 4) associé. Les cylindres supérieurs (3, 4) et les cylindres nettoyeurs associés (5, 6) sont maintenus par le même élément de retenue (7) et peuvent être ajustés de manière commune à l'aide de cet élément de retenue par rapport au bras de support et de charge (1) des cylindres supérieurs. L'élément de retenue (7) selon la présente invention peut être fabriqué de manière peu onéreuse. Il est compact et simple à monter et permet une réduction considérable de l'effort manuel à fournir lors d'un nouvel ajustement de l'écartement du système d'étirage.
