Definitions

  • the invention relates to a drafting system for a spinning machine, with a pneumatic compression device, which a means of transport Perforations and a suction device connected to it via a suction opening has, which on the side facing away from a fiber structure Transport means between at least one output roller and a delivery device extends, in the effective area of the suction opening, the suction device opposite, a shielding element is arranged.
  • Such a construction already belongs to the prior art (DE 198 15 325 A1), in which between a drafting system and a rotation and winding device a perforated compression element below a screen is arranged.
  • the output bottom roller is formed as a perforated suction roll
  • the aforementioned umbrella has deflecting functions and should influence the air flow in such a way that this affects the fiber structure from both sides and thereby the quality of the yarn improved.
  • the distances of these screens to the suction lower rollers must be set individually on each pair of spinning units and as a result of their mobility the load carrier of the drafting system is checked regularly.
  • the present invention is based on the object pneumatic compression drafting system of the type mentioned Reduce the effort for setting and adjusting shielding elements, at the same time the energy consumption for generating the negative pressure through Optimization of the suction air flow should be reduced, but without this To make it difficult to operate the drafting system.
  • This object is achieved in that it is a continuous profile trained shielding element extends over several spinning positions and below the stretching field level is attached to the machine frame.
  • the shielding elements of several suction devices are thus combined, shielding elements section by section for more than four spinning positions can be summarized. For example, four, six, eight, ten and twelve spinning positions can be assigned to a shielding element.
  • These shielding elements can in a further embodiment of the invention as a continuous Profile with T or V-shaped cross-section or polygonal be, this profile advantageously below the stretching field level located. In contrast to the prior art, this arrangement allows one large-scale training of the shielding elements without the operation of the Hinder drafting system.
  • the ends of the profile on the machine frame preferably at the bearing points of the drafting roller be attached.
  • the bearing points can be provided with a recess be in which the profile rail, d. H. the shielding element, inserted from above can be.
  • the one opposite the suction opening Area of the respective shielding element of the contour of the tread be adapted to the means of transport.
  • the aforementioned surface of the shielding element is hollow is trained.
  • Figure 1 is a drafting system 1 for a spinning machine for bundling a the drafting to be warped fiber structure 2 shown.
  • a first pair of rollers 5 and a second pair of rollers 6 application the a pair of output rollers 10 is arranged downstream of the second pair of rollers 6.
  • the main warping of the fiber structure 2 takes place.
  • a pneumatic compaction device connects to the output roller pair 10 30 on.
  • This is a delivery device in the form of another Subordinate pair of rollers 35.
  • the area between the pair of exit rollers 10 and the delivery device 35 represents a so-called fiber bundling zone.
  • the one leaving the output roller pair 10 of the drafting system 1 becomes Fiber dressing 2 over the corresponding length one transverse to the direction of transport directional suction air flow exposed. You can do this with perforations 45 provided means of transport 15, for example a strap, application Find.
  • suction opening 22 there is a suction opening 22 and a suction device connected to it 25 is provided, which face away from the fiber structure 2 Side of the transport means 15 between the pair of output rollers 10 and Delivery device 35 extends.
  • This suction device 25 has a suction shoe 26 over which the perforated strap, i.e. H. the means of transport 15, is performed.
  • the suction shoe 26 is connected to a suction line 27, which is connected to a vacuum source, not shown.
  • shielding element 40 is arranged in the effective area of the suction opening 22, the suction device 25 opposite, a shielding element 40 is arranged.
  • This shielding element 40 is designed as a continuous profile, in the embodiment of Figure 1 with a T-shaped cross section. It extends according to the figure 2 over several spinning positions I and II and is below the drawing field level attached to the machine frame. Preferably several shielding elements 40 sections can be combined over more than four spinning stations.
  • the bearing points 20 each have a corresponding one Counter profile for receiving the ends of the shielding elements 40.1 and 40.2. So that the relevant profile, d. H. the respective shielding element, be inserted into the respective bearing 20 from above. hereby are advantageously no adjustment work for the shielding elements in question 40.1 and 40.2 required as their position for all spinning positions is fixed in this section.
  • FIG 3 is similar to that of FIGS. 1 and 2, however, the profile, i.e. H. the shielding element 40 'in cross section V-shape having. Again, the bearing 20 in question is designed accordingly, in order to functionally secure the shielding element 40 'inserted from above holders.
  • the shielding element whose opposite the suction opening 22 of the Contour of the tread of the transport means 15 is adapted.
  • the large-area shielding elements 40, 40 'and 40 "make it more advantageous Way optimizes the suction air flow, while at the same time the energy requirement for Generation of the required negative pressure drops. Despite this beneficial effect is the operation of the drafting system, especially the threading when piecing and performing cleaning work, not hindered. About that in addition, the effort for setting and adjusting the shielding elements becomes significant prevented.
