Definitions

  • the invention relates to a sliver guide device with a guide element arranged between two pairs of rollers at a work station of a spinning machine.
  • the object of the present invention is to provide a sliver guide device which is a simple safe reinsertion of the sliver end into the nip of the downstream pair of rollers allowed.
  • the guide element is a length-adjustable sliver guide channel which is fastened between the two pairs of rollers and the end regions of which project into the nips of the two pairs of rollers.
  • This sliver guide channel can be formed by two telescopically guided tubes that are pressed apart by spring force and clamped between the two roller pairs, the width of the sliver guide channel being based on the traversing width of the sliver in the feed roller pair and on the outlet side on the traversing width of the fuse in the feed roller pair immediately following pair of rollers can be turned off. This ensures that the fuse can run into or run out of the channel in all positions of its traversing width.
  • the inner telescopic tube is arranged on the inlet side of the sliver channel according to a further feature of the invention.
  • the two telescopic channel parts each have a slot to enable the fuse to be inserted, the two slots being aligned with one another.
  • the end regions of the two telescopic tubes encompass the lower rollers of the assigned roller pairs up to their middle, so that the Luntenka nal is held in position when swiveling a support and load arm guiding the top rollers.
  • lateral movement of the sliver guide channel is prevented by cheeks designed as a guide, which are supported on the flanks of the corrugated field which is increased compared to the basic diameter of the rollers.
  • At least one housing of the sliver guide channel can be designed so narrow that two housings can be arranged side by side between two pairs of rollers for guiding two slivers separately through the work station.
  • This has the advantage that two sliver guides arranged side by side guide the roving or the sliver separately at the intended distance. Arranged individually, these match guides can be used for normal spinning.
  • the displaceable tube can advantageously be on the inlet side of the sliver guide device.
  • the tube of the housing which is arranged downstream in the direction of the roving, is constricted on its outlet side in the roving area, thereby improving the guiding effect in the outlet area.
  • a locking device which fixes the position of the displaceable tube and which can be designed, for example, as a grid.
  • the spring presses the displaceable part of the sliver guide device into the roller gap of the roller pair in front of it.
  • the position of the front displaceable tube is determined by the locking depending on the distance between the two pairs of rollers between which the sliver guide device is arranged, which has the advantage that the front movable part does not drag on the preceding pair of rollers.
  • FIG. 1 shows schematically a drafting system, i.e. a work place of a spinning machine. It can be seen that this drafting system consists of a pair of input rollers 1, a middle pair of rollers 2 with upper straps 6 and lower straps 7 and an output roller pair 3. The upper strap 6 and the lower strap 7 of the middle pair of rollers 2 are guided and tensioned in a manner not shown, but known per se, by appropriate guides.
  • the input roller pair 1 which consists of an upper roller 4 and a lower roller 5 and the middle roller pair 2, there is a sliver guide device with a sliver guide channel 8.
  • This sliver guide channel 8 is telescopically guided into one another, pressed apart by the force of a spring 11, formed between the two pairs of rollers 1 and 2 clamped telescopic tubes 9 and 10.
  • the inner telescopic tube 10 is arranged on the inlet side of the sliver guide channel 8, i.e. in the area of the input roller pair 1.
  • the two telescopic tubes 9 and 10 each have a slot 12 and 13 leading into the sliver guide channel 8 according to FIGS. 2 and 3.
  • the two telescopic tubes 9 and 10 according to FIG. 3 each have a guide 14 and 15 or 16 and 17 at the end, which are designed as cheeks. These cheeks prevent lateral movement of the sliver guide channel, the guides 14 and 15 or 16 and 17 being supported on the flanks of the corrugated field, which is increased in relation to the basic diameter of the rollers of the roller pairs 1 and 2, of at least one of the lower rollers of the two aforementioned roller pairs.
  • the width B of the sliver guide channel 8 in the direction of the drafting system level on its inlet side is so large that the sliver can run into the guide channel 8 in the region of the telescopic tube 10 in all positions of its traversing width.
  • the outlet width B 'in the following telescopic tube 9 is so large that the traversing of the fuse in the subsequent pair of rollers 2 can continue.
  • a sliver guide device with a guide channel 8 within the two telescopic tubes 9 and 10 is advantageous if, for example, drafting systems of spinning machines with sliver stop devices per se known type.
  • the upper roller 4 is lifted from the lower roller 5 of the pair of rollers 1 in a manner not shown by a wedge-shaped clamping element inserted between the pair of input rollers, stopped and the fuse is clamped. Since the downstream roller pair 2 continues with the lower aprons 6 and 7, the fuse is separated between these two roller pairs.
  • the sliver guide device with the sliver guide channel 8 is provided within the two telescopic tubes 9 and 10. Since these two telescopic tubes 9 and 10 are supported under the action of the spring 11 between the two pairs of rollers 1 and 2 and the inner telescopic tube 10 is guided within the telescopic tube 9 over a longer area, the guide of the fuse is also with larger changes in the distance between the two pairs of rollers 1 and 2 given perfectly.
  • the sliver guide channel 8 also protects the sliver barrel against the possible undesired action of a traveling blower which runs along the spinning machine and blows off dust and fiber deposits from the drafting elements by means of an air stream. This ensures that the fuse is guided covered within the fuse guide channel and cannot be blown.
  • roller pairs 1 and 2 there is a sliver guide device between the roller pairs 1 and 2.
  • the sliver guide device consists of a housing which accommodates the two tubes 9 which are guided telescopically one inside the other and has 10.
  • the housing of this sliver guide device is so narrow that, according to FIG. 5, two housings 24, 25 for separately guiding two slivers 22, 23 can be arranged between the roller pairs 1 and 2 through the work station.
  • Each of these two housings 24 and 25 has a sliver guide channel 8.
  • the sliver guide device according to the invention with the sliver guide channel 8 is shown in more detail in FIG. 6.
  • the one tube 9 of the sliver guide device is fastened to a holding rail 30, advantageously clipped on by projecting claws which are not designated in any more detail; the other tube 10 is designed to be displaceable.
  • a spring 29 is arranged which pushes the displaceable tube 10 against the pair of rollers 1 and its inlet opening in its roller gap.
  • the displaceable tube 10 is advantageously located on the inlet side of the sliver guide device, i.e. in the area of the pair of rollers 1. Projecting stops 34 and 35 on both tubes 9 and 10 prevent the spring 29 from pushing apart the two aforementioned tubes, for example in the removed state.
  • the tube 9 of the housing 24 or 25 arranged downstream in the direction of the roving is provided with a constriction 36 on its outlet side in the roving running area, the roving guide channel 8 in this area via conical surfaces 40 and 41 in this constriction 36 passes over.
  • the respective fuse 22 or 23 in the outlet area of the fuse guide device advantageously experiences not only very good guidance transversely to the direction of travel, but also a lateral summary which advantageously influences the warping work of the downstream main warping field.
  • constriction 36 is limited to the lower region of the sliver guide channel 8, in which the slips 22 and 23 run during normal operation of the drafting system.
  • the upper, further developed area makes it easier to insert the fuse when starting up the drafting system; due to the funnel-like transition from the more developed to the narrow area, the fuselages pull themselves into the narrow area under the effect of the pulling force.
  • the tube 9 fastened to the holding rail 30 has grids 38 below the top surface; the displaceable tube 10 is provided with a latching element 39 which can engage in one of the detents 38 of the tube 9.
  • the area of the tube 10 which carries the latching element 39 is designed as a resilient tongue.
  • the housing 24 or 25 of the sliver guide device Due to the narrow design of the housing 24 or 25 of the sliver guide device, it is possible to provide it when using the drafting device for spinning twisting, in which two slugs 22 and 23 are spaced a short distance apart by the The drafting system is running and is only brought together after the drafting system has been lowered.
  • the front movable tube 10 of the sliver guide device is adapted in its contour to the gap between the roller pair 1 in order to get as close as possible to the area of this roller pair. 6 and 7, this contour 33 can be seen in the area of the sliver guide channel 8.
