Definitions

  • the invention relates to a tape guide placed on a guide table, e.g. is attached to a discharge table of a combing machine in order to deflect a combed belt emerging from a combing head of the machine.
  • Common combing machines have a number of combing heads, from each of which a comb belt emerges on a common outlet table. On the exit table, the sliver belts are guided around a belt guide and then run together to a drafting system.
  • the band leaders common today are simple, e.g. cylindrical pins, for example, which are usually fastened adjustable on the outlet table, e.g. with one eccentrically arranged screw parallel to the pin axis.
  • a disadvantage of these known belt guides is that individual fibers can jam and get caught on the combed belts in the corner between the circumferential surface of the pin and the surface of the outlet table. More fibers accumulate, and a fiber braid is formed, which is finally carried away by the running web and then leads to faults, e.g. to shut down the drafting system and the entire machine.
  • Another disadvantage is that the combed belt deposits deposits on the belt guide over time, e.g. Honeydew, resin, shell parts, finishing agents, etc. Such contaminations, if not removed at short intervals, lead to an increase in friction, which can tear the tape and deteriorate its quality (uniformity).
  • the object of the invention is to avoid the disadvantages described.
  • a tape guide of the type specified which is known in accordance with the invention is characterized by a sleeve which is rotatably mounted on an inner element fastened to the outlet table and which, adjacent to the surface of the outlet table, has a radially outwardly projecting flange for supporting the combed belt.
  • the comb-tension belt can run around the belt guide, supported by the flange on the sleeve, so that individual fibers of the belt cannot become jammed between the belt guide and the surface of the outlet table.
  • the idea here is that the running comb belt takes the rotatably mounted sleeve with it and turns it around its axis so that there is no sliding friction between the belt and the sleeve. This largely eliminates the risk that the sliver belt could deposit impurities on the sleeve.
  • the sleeve can easily be made of plastic, since there is no fear of a static charge on the combed belt.
  • the inner element can of course also consist of plastic. Individual fibers that should still get caught can easily come loose from the rotating sleeve before the formation of braids can occur.
  • Fig. 1 shows schematically a combing machine with a number of combing heads 1, each delivering a combed belt 2 to a common outlet table 3.
  • a belt guide 4 is arranged on the outlet table 3, which deflects the relevant combed belt 2 in the longitudinal direction of the outlet table.
  • the deflected sliver bands 2 then run together to a drafting system which is accommodated in a housing part 5.
  • the tape guide 4 has a sleeve 11, preferably made of plastic, with an essentially cylindrical peripheral wall.
  • the sleeve 11 is rotatably mounted on an inner element 12 in the form of an approximately cylindrical, hollow pin, which can also consist of plastic.
  • the inner element 12 is fastened on the outlet table 3 with a screw 13 which is screwed into a threaded bore or threaded sleeve 14 in the inner element 12.
  • the threaded bore or threaded sleeve 14 runs parallel to the axis of the sleeve 11 and the inner element 12, but eccentrically to this axis, so that the inner element 12 together with the sleeve 11 can be pivoted about the axis of the screw 13 before tightening the screw 13 adjust the path length or the distance between the belt guide 4 and the table edge in order to secure the belt transport.
  • a radially outwardly projecting flange 15 is formed adjacent to the surface of the outlet table 3, on which, during operation, the sliver belt running around the belt guide 4 is supported.
  • the width of the flange 15 can be approximately equal to the diameter of the combed belt, that is to say that the outside diameter of the flange 15 can be 15 to 30 mm larger than the outside diameter of the peripheral wall of the sleeve 11, for example.
  • the outer surface of the peripheral wall of the sleeve 11 merges with a curve 16 with a radius of curvature r (in axial section) of approximately 2 to 8 mm into the top surface of the flange 15. This ensures a gentle deflection of the sliver and a good rotation of the sleeve 11 by the running sliver.
  • the sleeve 11 on the inner element 12 should be rotatable as easily as possible.
  • the bottom surface of the flange 15 preferably has one from the surface of the discharge table 3 small distance d of about 1 mm.
  • the sleeve 11 is supported on the upper end face of the inner element 12, preferably with an upper transverse wall 17 which is closed so that no dust or fiber fly can penetrate from above between the peripheral wall of the sleeve 11 and the inner element 12.
  • the underside surface of the transverse wall 17 has a projection 18 in its central region, so that it only rests on the upper end surface of the inner element 12 in this central region.
  • the same effect could also be achieved with a flat underside surface of the transverse wall 17 and a projection on the middle area of the upper end face of the inner element.
  • the sleeve 11 could be rotatably supported by means of a ball bearing on an inner element fastened to the outlet table 3.
  • the slide bearing described results in a sufficiently easy rotatability of the sleeve.
  • an eccentric bolt could be held in the inner element instead of the threaded bore 14, which extends through a bore in the outlet table 3.
  • the adjustable fastening of the inner element there are also various other options for the adjustable fastening of the inner element.
  • the embodiment is directed to the use of the tape guide in a combing machine. However, it is conceivable to use this tape guide in other places. Wherever fiber slivers have to be redirected, e.g. also at the infeed table of a line.
