Definitions

  • the invention relates to a resolving device according to the Preamble of claim 1.
  • the high Circumferential speeds of the opening roller during rotor spinning contribute to an uneven resolution of the Fiber template and an increased removal of not or only to avoid incompletely resolved tufts of fibers.
  • the opening roller usually with a Speed of about 8,000 revolutions per minute the speed of the opening roller during friction or air spinning due to the aforementioned conditions, for example 1,800 revolutions per minute.
  • the speeds of the opening roller are the occurring ones Centrifugal forces so reduced that the loosening of the fibers from the opening roller is insufficiently supported.
  • the Transfer of fibers from the opening roller to the respective one Collecting element, for example a perforated suction roller Coat is accordingly bad.
  • the combing or opening elements for example There are needles that are not in the direction of the opening roller are inclined.
  • Dissolving elements on opening rollers are usually below an angle of 15 to 20 degrees in the direction of travel Opening roller inclined to the retraction of the fibers and the Combing out the free end of the fiber template, the so-called fiber beard to favor.
  • the in the running direction The front edge of the opening element is used in saw tooth sets Toothbrush called, the inclination in the direction of rotation as positive Breast angle is called.
  • a positive chest angle however, makes it difficult to detach the fibers from the opening roller.
  • Fiber templates made from a blend of polyester and Cotton are made to dissolve satisfactorily and that To hand over the collective organ. After a short time, often after a few seconds, fibers are wrapped around the Opening roller, and the opening process is permanently disrupted or completely prevented.
  • From DE-AS 24 18 516 is a needle roller for feeding a Sliver for combing an open-end spinning device known, between the needles are bendable rods.
  • the Rods are supposed to be an elastic pad into which the needles are placed a known device embedded up to its tip are, replace and a wrap on the needle roller prevent.
  • the bars extend between two at the both ends of the roller arranged supports and allow compression or compression of the Sliver at the points where it rests on the rods.
  • the sliver is fed through the rods to the feed table pressed. In order for this pressure to be exerted, the sliver must be so compact and thick that it pulls the rods out of their rest position deflects.
  • the use of the bendable rods is therefore at a resolver limited to the feed roller.
  • CH-PS 620 949 describes a feed roller for one Combing cylinders in radial bores of the feed roller jacket has guided needles.
  • the needles are between one Pull and an extended position moves. This is supposed to Dissolve the fibers between the feed roller and the comber roller be improved.
  • a device with movable needles is mechanically complex and prone to failure. Through the movement the needles in the radial direction become fibers in pulled the gap between the needle and roller shell and get stuck there. When retracting the needles clamp the fibers in the radial bore and the needle block by wedge action. The use of saw teeth instead of needles it is not possible at all. Such devices have not prevailed.
  • DE 196 08 828 A1 shows an opening roller with Openings for generating radial air currents on the circumference is provided.
  • the opening roller is with a set of teeth equipped.
  • the generic DE 198 50 518 A1 shows an opening roller, which the fiber beard together with a support roller combs out. This allows an additional Avoid compressed air consumption. The dissolution of slivers is improved, but not the problem of wrapping Fibers or inadequate handover of the fibers from the Opening roller to the collecting organ fixed.
  • the invention is based, the function of the task Improve opening roller.
  • the air pressure and thus the air consumption compared to known ones Devices used to detach the fibers from compressed air contribute to be significantly reduced.
  • the negative pressure that leads to Suction of an opening roller is needed for example, can be reduced from 130 mbar to 50 mbar.
  • the Stretching of the fibers during the transfer is improved.
  • the opening device according to the invention has according to Claim 3, claim 4 and claim 5 between the Dissolving elements arranged transversely to the direction of rotation movable ejectors extending over the opening roller, which is preferably pivotally attached to the opening roller are.
  • People is advantageous essentially across Direction of rotation of the opening roller extending row of An ejector is assigned to opening elements.
  • Such ejectors allow it in a simple way when reaching for the Place provided on the orbit for fiber transmission an evenly distributed across the width and to ensure reliable detachment of the entrained fibers.
  • a trained as a wire bracket according to claim 6 Ejector is easy and inexpensive to manufacture, easy through holes on both sides of the opening roller fasten and has only a small mass that can be moved got to.
  • a stationary annular guide designed in such a way and arranged that under their influence the location of the respective rotating ejector cyclically to the opening roller changed.
  • One cycle corresponds to one revolution of the Opening roller.
  • the leadership is advantageous designed that inevitably through the curve Immersion of the ejector between the opening elements causes the respective rotating ejector as it passes the combing point farthest between the dissolving elements immersed and when passing the point at which the Separate fibers from the opening roller, the farthest from the Base body of the opening roller is lifted off. That's how they are Fibers always above the ejector, and the stripping process can be carried out without difficulty.
  • the opening device according to the invention takes up little space and requires only a small amount of additional Components compared to a normal usual opening roller and can be produced inexpensively.
  • the resolving device according to the invention is next to the Use for spinning processes in which due to the Demand for constantly stretched fibers the speed of the Opening roller is limited, also suitable on open-end rotor spinning machines to be used to have fibers there large winding tendency to dissolve, circulation fibers respectively To prevent the formation of wraps or, for example, to lower gently To enable speeds of the opening rollers in chemical fibers.
  • FIG. 1 At the spinning position shown in Figure 1 is a Sliver 1 passed through a spreading device 2 and in spread state of the opening device 3 presented.
  • the Feed trough 4 presses the spread sliver 1 against the Feed roller 5 and forms with the feed roller 5 Nip that the end of the sliver 1, the so-called Beard, holds back.
  • the opening roller 6 combs the fiber beard and dissolves the sliver 1 down to the single fiber.
  • Die Fibers are taken over by a vacuumed take-off roller 8 and brought together into a narrow ribbon.
  • the direction of rotation of the take-off roller 8 is indicated by the arrow 9 indicated.
  • the take-off roller 8 and the pinch roller 10 form a clamping line that is traversed by the ribbon.
  • the air spinning device 11 generates an air vortex which is used for Thread formation serves.
  • Such air spinning devices are known for example from DE 196 10 960 A1.
  • the thread 12 passes a trigger device 13 and becomes one For reasons of simplification, winding unit not shown promoted.
  • the Opening roller 6 engages with the needles 14 Dissolving elements in the fiber beard of the sliver 1 and combs out fibers.
  • the inner contour 15 of the stationary annular guide 16 runs so eccentrically to the opening roller 6 that on Comb point the distance between the inner contour 15 and the Opening roller 6 is the lowest and in the area of the transfer zone to the take-off roller 8 is largest.
  • On the inner contour 15 are those designed as a symmetrical wire bracket Ejector 17 with a section.
  • the ejectors 17 are pivotable on side rims 18 of the opening roller 6 attached and thus run together with the opening roller 6 in Direction of arrow 19 around.
  • Each ejector 17 is in introduced into the shelves 18 on both sides opposite bores held.
  • the opening roller 6 the ejector 17 with a steady Centrifugal force applied to the inner contour 15 of the Guide 16 pressed.
  • the guide 16 is a plastic ring executed so that the ejector easily on the Inner contour 15 can slide. Because at the point of combing out the distance between inner contour 15 and opening roller 6 is low the ejector 17 out through the inner contour 15 so that they when passing the combing point farthest between the Immerse the needles 14. This position of the ejector also shows the Perspective view of Figure 3. The tips of the Needles 14 protrude beyond ejectors 17.
  • FIG. 4 shows an embodiment of the opening device in which one spring 31 acts on the ejector 17.
  • the Spring 31 is designed as a compression spring and acts on the Ejector 17 with a substantially radially outward directed force. The effect of the spring 31 Centrifugal force, due to which the ejector 17 to the Inner contour of the guide 16 is pressed, supported. In a further embodiment, not shown one spring 31 at each end of the ejector 17 attack.
  • FIG 6 and Figure 7 show a portion of a Opening roller 20, the opening elements of which are teeth 21 are trained.
  • An opening roller with a suitable set is known for example from DE 34 39 664 C2.
  • the structure the opening device is analogous to the opening device 3 in Figures 1 and 2, the deviation essentially is that the opening roller 20 teeth 21 instead of needles having.
  • Figure 6 shows the position of the ejector 22 when passing the Comb point relative to the opening roller 20.
  • the ejectors 22 lie with the crossbar on the partially dashed shown inner contour 23 of the guide 24 and dive deep in the incisions 25 between those in the axial direction formed rows of teeth.
  • the incisions 25 are through the Chest surfaces 26 and back surfaces 27 of teeth 21 limited.
  • the teeth 21 have a positive breast angle ⁇ . On positive breast angle ⁇ , in particular a large breast angle ⁇ , contributes significantly to a good dissolution of the fiber material at.
