Definitions

  • the present invention relates to a device for cleaning the set of covers of a revolving card, according to the preamble of claim 1.
  • the reel which is provided with needles on its cylindrical surface, takes with it the fiber material fed to it and moves it between its clothing and that of the cover of the card cover set, which normally moves in the opposite direction.
  • the fibers of the fiber material are thereby parallelized. They also undergo cleaning. Contaminants such as shell parts, nits and the like accumulate in the card cover sets. These sets must therefore be continuously cleaned again during the operation of the card. This takes place in a cleaning zone located outside the carding zone by means of brushes immersed in the clothing of the cover.
  • the cover plaster is released from the set of covers with a swinging brush and enters the path of movement of a swinging comb as a coherent fleece. This pierces the fleece with its needles and separates strips from the fleece web, which fall off the vibrating comb when the needles of the vibrating comb are in a vertical position.
  • a rotating brush also cleans the lid set from bowls and the like.
  • This cleaning device has the disadvantage that the cover set is not cleaned with sufficient thoroughness and the impurities are not removed from the set to a sufficient extent.
  • German Patent No. 52 845 a device for cleaning the lid set according to the preamble of the first claim is known from German Patent No. 52 845.
  • the carrier of the cleaning brush can be moved linearly by means of a cam guide in the direction against the cover set and in the opposite direction, and can be pivoted by means of a second groove guide, so that the cleaning brush is able to swivel into the set in one direction due to the two groove guides Penetrate lid and swing past it in the backward motion.
  • the advantage of our invention is that it is much easier and easier to use and that it is flexible enough to get good technological results.
  • a rotatable drum 11 of a card is shown, on the cylindrical surface of which needles 12 are attached.
  • a traveling cover set comprises individual covers 13, each of which is provided with a clothing 14. The revolving cover set moves relatively slowly in the direction of arrow 15 during operation.
  • a brush 16 that extends over the entire width of the card is included a shaft 17 firmly connected and with this about its axis 18 between the dashed positions A and B and the position C, as indicated by the double arrow 19, pivotable.
  • the shaft 17 extends between two plates 20 perpendicular to it, one plate of which is visible. It is carried by the plates 20.
  • the latter also carry a comb 21.
  • the plates are assembled to form a unit by components, not shown, which forms a carrier for the shaft 17.
  • reference numeral 20 is intended to designate both the plates and the carrier.
  • a support rod 22 is also provided, which is fastened to the card frame and is used for pivotably supporting the plates 20.
  • these plates 20 are carried by one end of a cylinder-piston unit 23, the other end of which is fastened to a fastening point 24 on the card frame.
  • the piston of the unit 23 can be moved in one direction by means of a pressure fluid and in the other direction by means of a pressure spring.
  • the pressure fluid is introduced into the cylinder via a valve 25.
  • the valve 25 can be controlled by means of a control means, which is not shown and is known per se.
  • the lid set moves slowly (eg 25 cm / min.) In the direction shown by arrow 15.
  • the brush 16 carries out swivels (for example 40 / min.).
  • the swivels move in a cleaning movement (serving to clean the clothing) from position A via position C to position B and in a return movement back to position A.
  • Position C represents the point at which the clothing 14 of the cover 13 is cleaned, that is to say the cover cleaning point. Since this coincides with the position C, it is also designated with the reference symbol C below.
  • the unit 23 is operated in the rhythm of the pivoting movements of the brush 16.
  • a pressure is exerted on the piston of the unit 23 by the pressure fluid, as a result of which this piston moves away from the fastening point 24 while compressing the compression spring present in the unit 23.
  • the plates 20 are pivoted about the support rod 22 counterclockwise.
  • a unit 23 forming a drive means can be provided for each of the plates 20, or a unit 23 forming a drive means common to both plates 20. Since the shaft 17 is carried by the plates or the carrier 20, the distance between the movement path of the brush 16 and the set of covers, i.e. the plates 20 and thus the path of movement of the brush 16 are brought into a position at the cleaning point C from the set of covers.
  • the valve 25 of the unit 23 can be actuated by a control means known per se and therefore not shown. This can be based on an electrical circuit, for example.
  • a control means known per se and therefore not shown. This can be based on an electrical circuit, for example.
  • the piston of the cylinder-piston unit 23 is moved and the carrier 20 is moved via this piston.
  • the return movement of the piston is brought about by an outflow of the pressure medium from the cylinder controlled by the control means and by the prestressed compression or return spring.
  • the plates 20 are given clockwise around the support rod 22 and the support 20 comes into a position close to the set of covers at the cleaning point C.
  • other control means such as cam disks and the like can be used to control unit 23. In the case of the latter means both the control means and the drive means.
  • the immersion depth of the brush 16 set in the cover 14 set 13 can be chosen as desired. This enables optimal cleaning of the clothing 14 and adaptation to different conditions.
  • the brush 16 After the brush 16 has started its return movement from the position B, it brushes through the comb 21, the cover plaster 26 held by it falling off, provided that this does not fall off when the brushing is carried out on the occasion of the cleaning movement from position A to position B. is.
  • the cover plaster is removed via a collecting container 27.
  • the comb 21 is attached to the plates 20.
  • the support rod 22 is advantageously mounted close to a side edge of the plates 20 in such a way that, as shown in FIGS. 1 and 2, the brush set located at the cleaning point C and the support rod 22 are approximately the same height above an imaginary one the horizontal surface of the lid set is at the level defined at the lid cleaning point C. This results in the desired movement of the carrier 20 at the cleaning point C in the direction perpendicular to the set of covers up and down.
  • cover 13 of a cover set of a revolving flat card is shown, of which each cover 13 is provided with a clothing 14.
  • the direction of movement of the cover 13 is indicated by the arrow 15.
  • a brush 16 is in turn carried by a shaft 17 and can be pivoted about its axis 18 between positions A and B via position C, as indicated by the double arrow 19.
  • the shaft 17 is supported by two plates 20 which are perpendicular to it and form a support.
  • a comb 28 for cleaning the brush 16 is firmly attached to the card frame (not shown).
  • a support rod 22 and a cylinder-piston unit 23, which serves as drive means, are also provided.
  • the unit 23 in turn serves to pivot the plates or the carrier 20 for the purpose of varying the distance of the path of movement of the brush 16 from the set of covers formed by the covers 13 or from the sets 14 thereof at the cleaning point C.
  • a collecting container 27 is also provided for the cover plaster.
  • a further cylinder-piston unit 29 is provided as the drive means in accordance with the embodiment in FIG. 2. This unit is used to move the plates 20 in translational movements parallel to the longitudinal extension of the cover set at the cleaning point C. In order to enable such movements, the plates 20 are provided with slots 30. The plates 20 are carried by the support rod 22 and the unit 23. The lid cleaning point is again the area of the brush 16 located in position C.
  • the brush 16 is therefore capable of the following movement components: Swiveling movements a, b, movements perpendicular to the surface of the cover set c, d, movements parallel to the longitudinal extent of the cover set e, f.
  • Swiveling movements a, b movements perpendicular to the surface of the cover set c
  • d movements parallel to the longitudinal extent of the cover set e, f.
  • the movements according to components a and c are carried out at the start of cleaning movement a.
  • component f is carried out and immediately thereafter the movement according to component d is carried out.
  • FIG. 3 the thick solid line shows the course of a given point of the brush 16. This is the point 39 in FIG. 2, for example.
  • the clothing 14 is also shown.
  • Position 31 denotes the location the axis 18 before the start of the cleaning movement a of the brush 16, position 32 the position of the axis 18 after performing the movement c by means of the unit 23, position 33 the position of the axis 18 after performing the movement f by means of the unit 29 and position 34 the position the axis 18 after executing the two movements c and f.
  • the point 39 of the brush 16 which executes a pivoting movement describes one of the circular paths shown, namely the circular path 35 at position 31 and the circular path 36 at position 32 , to position 33 the circular path 36, to position 33 the circular path 37 and to position 34 the circular path 38.
  • point 39 describes one of the thickly drawn out lines Line corresponding train. This initially runs along the circle 35 and ends in the circle 38.
  • the plates 20 are brought back into their position by executing the movement component d the cleaning point C removed from the lid set.
  • the movement of point 39 is brought to circle 37 belonging to position 33.
  • the course of this process is shown in FIG. 3. After the latter has ended and before the brush 16 has again carried out its return movement according to component b, a movement according to component e must be carried out at some point. This brings the brush arriving in position A at the end of its return movement b back onto the circular path 35.
  • the movement f takes place while the brush 16 moves over the cleaning point C.
  • the brush 16 plunges vigorously into the clothing during this working phase, the immersion depth being given by the choice of the size of the movement c.
  • the speed at which the brush 16 moves through the clothing 14 is slowed down by superimposing component f with component a. It is equal to the peripheral speed reduced by the speed of the movement f and given by the rotational speed of the brush. This results in an improved detection of the material to be removed.
  • component d moves at high speed, which is equivalent to tearing out vertically upwards. The combination of these processes contributes to greatly improved cleaning of the clothing 14.
  • the brush 16 is periodically moved through the comb 28 to clean it.
  • the comb 28 is not carried by the plates 20 forming a support, but is fixedly attached to the card frame.
  • a particularly advantageous embodiment is characterized in that in the working phase in which the brush is located in the area of position B, in the Cleaning movement a before the passage of the brush 16 through the comb 28, the plates 20 are again subjected to a movement c, and thus, together with the path of movement of the brush 16, are again placed in their position close to the cover at the cleaning point. This prevents the brush from dipping into the comb 28 during the cleaning movement a, so that no cover plaster is pushed into the brush during this.
  • FIG. 2 permits many other variants in addition to the examples shown.
  • adaptations to various conditions are possible.
