Definitions

  • the present invention relates to a method or a device for removing dust, waste and short fibres in the removal zone of a carder or carding machine, which has a stripper roller or doffer, a doffing cylinder, an upper and lower press roller, and a transverse conveyor belt.
  • Carders and carding machines are used for cleaning and opening cotton or other fibrous material. During these cleaning stages a large quantity of dust, short fibres and other waste is released and accumulates in the carder. When these agglomerates partially grown into flakes of dust and short fibres are again dragged along by the fibrous web or the sliver, this causes contamination or thick pockets in the final product of the carder or of the carding machines. These are extremely undesirable effects and can result in impairment to the subsequent spinning process.
  • a fibrous web is formed, concentrated by the transverse conveyor belt to form a sliver in the removal zone, defined by the arrangement of a stripper roller or doffer, a doffing cylinder, an upper and a lower press roller and optionally a transverse conveyor belt.
  • the fibres are transferred several times from roller to roller, with the corresponding arrangements of the rollers producing spaces where contamination can accumulate at will.
  • the result of this, caused by the small air movements, is that circular air movements, which also have a negative effect on removing this contamination, occur especially due to the press rollers in these spaces.
  • the degree of contamination in these spaces depends on the material to be processed, the production quantity, the degree of contamination of the raw material and the cleaning efficiency of the upstream cleaning processes, and also depends on general conditions such as temperature and relative humidity in the production plant.
  • a solution according to the present invention provides at least one of the following means:
  • a means for example a compressed air device, for generating a preset air flow in the region between the stripper roller, the doffing cylinders and the press rollers;
  • the compressed air device is positioned in the region between the stripper roller, the doffing cylinders and the press roller, such that the air current from the opening gap blows through between the lower press roller and stripper roller.
  • the air current should be such that it does not disturb or impede the normal course of web removal.
  • the duration of the generated air currents can be adjusted, depending on the degree of contamination.
  • the compressed air device can then selectively produce a continuous air current or operate at intervals, for example intervals of 1 to 60 minutes, advantageously 3 to 30 minutes, and produce an air blast for a duration of up to 60 seconds, preferably up to 10 seconds. It would be an advantage if the interval sequence and/or intensity were adjusted and/or regulated by the control unit, for example with an adjustable and/or controllable magnetic valve.
  • Each additional component conceals the danger of causing an accumulation of particles. Integration of two components can reduce possible attachment points for fibres. Because of this the compressed air device is integrated advantageously into a web baffle plate or a web baffle bridge, if available. Such integration should be done without influencing or impairing the function of the web baffle plate or the web baffle bridge.
  • the compressed air device can be made of any suitable material, advantageously from a hollow profile of chrome steel plate or aluminium, optionally anodised.
  • the profile can selectively be provided in the appropriate area with at least one slot or hole. Combinations of slotted, oval or round openings are conceivable.
  • the choice of form and number of holes is dependent on the working width of the entire compressed air profile and the number of feed positions for compressed air feed in the profile.
  • An example of a solution according to the present invention is a linear arrangement of several round holes with feed at the head or foot of the compressed air device.
  • the holes can also be arranged in a pattern or can be offset.
  • a waste baffle plate is attached below the gap, where dirt is blown out, which transports the dirt particles outside the carder shelling, from where they are removed during normal floor cleaning.
  • the construction of the waste baffle plate can also be of any suitable material, advantageously chrome steel plate or aluminium, optionally anodised. Antisoiling treatment of the surface of the material, for example a polished layer, can further still improve dirt removal.
  • An alternative solution would be to arrange an exhaust device under the gap.
  • This exhaust device can advantageously be attached to the already available central exhaust device of the carder. The dirt is directed to a filter system by this.
  • the inventive solution of removing the accumulated material is rather the arrangement of one or several exhaust devices for the space between the press roller and the transverse conveyor belt.
  • a decisive role can be played by how much unwanted material accumulates and whether an exhaust device is needed in the region of the sliver spout, where particles mostly accumulate, or over the entire working width of the carder. This can also be decisive, as to whether an exhaust device is needed at the top and/or bottom.
  • the sliver spout can be arranged in the middle or at the side; the partial exhaust device therefore also in the middle or at the side.
  • the exhaust device according to the present invention for the space above the upper mote knife and the crossbelt device is formed by an exhaust funnel, via which the air laden with dust and fibres is exhausted.
  • a similar arrangement is provided for the space next to the lower stripper and the lower press roller on the side of the crossbelt device.
  • These funnels can be made of any material.
  • the inside of the funnel can be treated with antisoiling.
  • Another solution according to the present invention for the lower exhaust device would be integration under the crossbelt device in the pivoting part, wherein the exhaust opening must be arranged laterally, depending on the overall construction.
  • the exhaust force in the upper and lower exhaust devices is dependent on the selected width and slot opening.
  • several separate exhaust devices can be provided on one side, preferably with a gradual exhaust force, increased in the direction of the actual sliver spout.
  • this can also be accomplished by adapting the suction slot and/or by subdividing the funnel into several chambers, for example a slot widening continuously in the direction of the sliver spout.
  • the strongest exhaustion should occur in the region of the fibre spout, though without impeding the sliver forming over the entire working width.
  • FIG. 1 shows a carder in diagrammatic representation
  • FIG. 2 shows the device according to the present invention in the region of removal
  • FIG. 3 is a front elevation of the device according to the present invention in the region of discharge of the card sliver/sliver.
  • FIG. 1 diagrammatically shows an example of a carder 1 .
  • Flakes of the carder 1 are fed into a flake filler shaft 2 .
  • the flakes reach the lower region of the flake filler shaft 2 at lickers-in 3 , 3 ′ and 3 ′′ of the carder 1 .
  • the three lickers-in 3 , 3 ′ and 3 ′′ open the fibre flakes.
  • the last licker-in 3 ′′ transfers the coarsely parallelised fibres to a carder drum 4 .
  • the carder drum 4 cooperates with flats 5 and parallelises the fibres further still.
  • FIG. 2 shows a detailed diagrammatic representation of the removal region of a carder.
  • the fibres are stripped off by the stripper roller 7 via a doffing cylinder 16 and with the aid of a web baffle bridge 13 guided in between two press rollers 8 , resulting in a fibrous web.
  • This fibrous web is concentrated by the transverse conveyor belt 17 and formed into a card band or sliver. Unwanted accumulations of dust, dirt and short fibres tend to occur in space A, which is delimited by the stripper roller 7 , the doffing cylinder 16 and partially by both the press rollers 8 .
  • a compressed air device 13 according to the present invention can be used to clean spaces A and exhaust devices 11 and 15 according to the present invention are provided for cleaning spaces B and C.
  • material throughput and proportion of short fibre and dirt are required.
  • individual cleaning components according to the present invention or combinations thereof are required.
  • the upper and lower exhaust devices can be arranged according to the present invention over the entire working width of the carder or just over a part thereof.
  • the region around the sliver spout is mostly at risk, because fibres and dirt dragged in here can be combined with the newly formed sliver.
  • FIG. 3 shows an arrangement with partial exhaust devices 11 and 15 in the form of a funnel above and below the sliver spouts (view of front working side, indicated in FIG. 1 by a star). In addition to this the flow of the exhaust air is shown.
  • the sliver 19 is transported forwards between the two conveyor belts 20 , 20 ′.
