Definitions

  • the present invention relates to a device for deriving and compacting a sliver on a spinning preparation machine, wherein a sliver for temporary storage or for further processing by means of rollers or belts is withdrawn, wherein before the rollers or belts at least one funnel is arranged, through which the sliver passes and thereby is compressed, according to the preamble of claim 1.
  • the sliver For cards or cans, it is known to compact the sliver to be deducted by a constriction, with the u.a. the mass flow of the sliver can be determined.
  • a constriction usually one or two-stage funnel are used, which have means in one form or another, to remove the air from the compacted sliver.
  • the amount and velocity of the air flowing out depends on the speed and volume of the fiber structure, as well as the degree of compaction in which the constriction is reached.
  • Two-stage funnels are known in the state of the art, which exert such great friction on the still unconsolidated sliver that the sliver can be damaged in that the air flowing out of the sliver entrains fiber particles, as a result of which the sliver may tear.
  • the sliver can be compacted by means of rotating rollers to the To reduce friction and operate at a higher speed, the spinning preparation machine can.
  • This device has the disadvantage that the control of the compression is very complex and this device is not compact enough for today's requirements and thus not space-saving in a storage head of a can tray or card exit can be integrated.
  • the object of the invention is the development of a device for deriving and compacting a sliver on a spinning preparation machine, which is simple and space-saving, and allows a high take-off speed of the sliver.
  • This object is achieved on the basis of a device for deriving and compacting a sliver on a spinning preparation machine, wherein a sliver for temporary storage or for further processing by means of rollers or belts is withdrawn, wherein before the rollers or belts at least one funnel is arranged, through which the sliver passes and is compressed, according to the preamble of claim 1 and with the respective characterizing features.
  • the invention includes the technical teaching that the sliver is precompressed before the hopper at least in two stages, wherein the pre-compression takes place by at least two compressor rings, wherein on all sides between the compressor rings and the hopper, a free space is arranged through which the air from the sliver can escape.
  • the distances between the compressor rings and between the compressor ring and the hopper are provided to vary in the material flow direction.
  • the distance between the second compressor ring in the material flow direction and the hopper by a 20% to 40% smaller distance than the distance between the first and second compressor ring. Due to the fact that most of the air escapes from the sliver through the first compressor ring, a corresponding clearance between the compressor rings must be created here. In the second compressor ring, a similarly high compression can take place, but the volume of air to be escaped is less, since the proportion of fibers compressed together is already very high.
  • the compressor rings and the funnel each have an opening through which the sliver runs and is thereby compressed.
  • This is advantageously circular for manufacturing reasons. She can, too For example, be oval or elliptical, the openings are then rotated at an angle to each other.
  • the diameter of the opening of the second compressor ring is smaller by 20% to 60%, preferably by 20% to 35%, than the diameter of the opening of the first compressor ring, results in a very gentle compression or compression of the sliver, which is only increased in the subsequent stage.
  • the funnel has an opening with a diameter that is 35% to 60% smaller than the diameter of the upstream in the direction of material flow compressor ring.
  • the funnel takes place between the second compressor ring and the funnel, the largest compression, which takes place due to the pre-compression by the first compressor ring, at high speeds without damaging the fibers.
  • both the compressor rings, as well as the funnel each have a radius which connects the respective end face with the opening edge-free. About this inlet radius, the actual compression of the sliver takes place.
  • the funnel can be designed as a funnel, which within a sliver funnel is arranged. Since the opening of the Vortrichters merges into a cylindrical bore after a constriction, and the subsequent sliver funnel usually has a further conical constriction for guiding and discharging the sliver into which a tongue of a probe can dip, resulting in this embodiment, a four-stage successive compression of the sliver.
  • the design and arrangement of the Vortrichters within a sliver funnel depends on, or in which spinning preparation machine the device according to the invention is used.
  • FIG. 1 shows by way of example the storage head 1 of a can changer in the open position.
  • About guide rollers, not shown sliver, for example, passed from a card to the storage head 1 of a can changer and out there through the funnel 16 with the arranged underneath the sliver hopper 17 through the opening 22 in a pot, not shown.
  • the take-off rolls 20, 21 provide for a continuous transport of the sliver in the arranged under the storage head 1 rotating cans.
  • the sliver can be stored in cycloid form in the pot, located below the storage head 1 is a turntable, not shown, on which a curved sliver channel is rotatably arranged.
  • the sliver can be clamped in the region of the sliver funnel 17 and be torn apart by increasing the distance of the sliver funnel 17 to the take-off rolls 20, 21.
  • the increase in the distance is effected by a cylinder 18 which, for example, pneumatically driven with its piston rod 19 engages an engagement element 13 below a pivot point 12.
  • Band funnel 17 and funnel 16 are arranged below a plate 10, which are reinforced on the underside by one or more angular reinforcing profiles 11 and pivotally mounted about a pivot point 12.
  • the two reinforcing profiles 11 are arranged at a distance in the region of one longitudinal side of the plate 10.
  • a rod which is formed as a pivot point 12, penetrates both reinforcing profiles 11 and is fixed to a frame 2 of the storage head 1.
  • a rod or a pipe is also formed as an engagement element 13, which also penetrates both reinforcing profiles 11.
  • the piston rod 19 of the cylinder 18 engages the engagement element 13 and pivots the belt hopper 17 in a circular arc of the take-off rollers 20, 21 away. During this movement, the sliver clamped in the belt hopper 17 or in the hopper 16 is separated.
  • a first compressor ring 15 are arranged with a second compressor ring 14, with which a voluminous strip is pre-compressed.
  • the piston rod 19 of the cylinder 18 is extended and presses the engagement element 13 about the pivot point 12 in a clockwise direction so that the belt hopper 17 with the hopper 16 is removed from the take-off rollers 20, 21 which are still in the closed position and the fiber ribbon is torn off.
  • the clamping of the sliver within the sliver funnel 17 can be effected by a clamping element, not shown, which is pneumatically actuated, for example, is arranged on or in a wall of the belt hopper 17 and jammed the sliver.
  • a clamping element not shown, which is pneumatically actuated, for example, is arranged on or in a wall of the belt hopper 17 and jammed the sliver.
  • the inner diameter of the hopper 16 and the belt hopper 17 may be set so close to the dimension of the sliver to be processed that jerky movement of the hopper 16 and belt hopper 17 away from the take-off rolls 20, 21 is sufficient to rupture the sliver.
  • the sliver funnel 17 could be cleaned with the funnel 16 in a sliver breakage.
  • Sliver has wound around the take-off rolls 20, 21, they must first be moved apart.
  • the device To operate during maintenance or cleaning, the device provides a lever 23, with the manually raised the belt hopper 17 and at the same time the take-off rollers 20, 21 can be moved apart.
  • FIG. 2 are parts of the storage head 1, which are not relevant to the invention, for example, the drives and the take-off rolls, shown very weak.
  • the first compressor ring 14 In the material flow direction, ie from the compressor ring 14 in the direction of funnel 16, the first compressor ring 14, a second compressor ring 15 and a funnel 16 are arranged at a distance from one another.
  • the areas between the first and second compressor ring 14, 15, and between the second compressor ring 15 and the hopper 16 are designed so that the air from the sliver can escape on all sides.
  • the compressor rings 14, 15 are fastened by means of fastening elements to brackets 24, 25, which in turn are arranged on a lateral attachment 26.
  • the brackets 24, 25 allow the compressor rings 14, 15 to float almost at a distance, with a free space on each side between the compressor rings 14 and 15, and the compressor ring 15 and the funnel 16, through which the air can escape into the atmosphere.
  • the distances between the compressor rings 14, 15 and between the compressor ring 15 and the funnel 16 may be fixed, so that an assembly consisting of compressor ring 14, holder 24, compressor ring 15, bracket 25 with the attachment 26 and associated spacer sleeves 27, 28th including funnels 16 for replacement for a particular fiber grade, for example, 6.5 ktex Turkish cotton, which is replaced when the fiber quality changes.
  • the distance between the compressor rings 14 and 15, and between the compressor ring 15 and the hopper 16 may be variably adjustable, which may be advantageous if the quality of the cotton to be processed varies in batches.
  • the diameters of the compressor rings 14, 15 and the funnel 16 decrease successively in the material flow direction.
  • the compressor rings 14, 15 and the funnel 16 have a centrally arranged circular opening or bore, in which a radius R14, R15, R16 extends over 90 ° completely from a surface or front side into the bore edge-free. In the material flow direction thus narrows the bore.
  • the diameters D14 and D15 of the compressor rings 14, 15 are determined at the narrowest point where the radius of the bore merges into a short cylindrical surface.
  • the radii R14, R15 and R16 are between 40% to 60% of the diameter D15.
  • the diameter reduction from the first compressor ring 14 may be between 20% to 60%, preferably 20% to 35%, up to the second compressor ring 15.
  • the second diameter reduction may be from 35% to 60% from the second compressor ring 15 to the hopper 16.
  • the inner diameter D14 of the compressor ring 14 is for example 35 mm.
  • the subsequent diameter D15 of the compressor ring 15 is then at 25 mm and the subsequent diameter D16 of the hopper 16 can therefore be at 10 mm.
  • the distances X1 between the first and second compressor rings 14, 15 and the distance X2 between the second compressor ring 15 and the hopper 16 decrease by 20% to 40%.
  • the arrangement with the decreasing distances X1 of the compressor rings 14, 15 to each other and X2 to the hopper 16 is based on the knowledge, that most of the air escapes in the first compressor stage, whereby the distance between the compressors should be correspondingly large. In the second compressor stage, although the largest compression takes place, the volume of air to be escaped is less, since the proportion of fibers compressed together is already very high.
  • the invention thus has the advantage that the sliver can be pulled compacted at a higher speed.
  • the complete spaced arrangement of the individual compressor stages to each other which allows an unrestricted escape of air from the sliver, allows the reduction of defects and partial tape breaks.
  • the air can escape through the full band cross-section.
  • the multi-stage compaction of the sliver allows a high compression of the sliver at a high take-off speed.
  • the embodiment of the invention relates only to the head of a can tray, which can be arranged on a track, carding machine or comber, use is possible on all spinning preparation machines, in which a sliver should be subtracted and compressed. In particular, the use of the output of a card is possible.
