Definitions

  • the present invention relates to a device for cleaning the lid set of a traveling decarding 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 covers 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 removed 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.
  • a revolving cover set comprises individual covers l3, each of which is provided with a set l4.
  • the revolving cover set moves relatively slowly in the direction of arrow l5 during operation.
  • a brush l6 which extends over the entire width of the card is fixedly connected to a shaft l7 and can be pivoted with it about its axis l8 between the positions A and B shown in broken lines and over the position C, as indicated by the double arrow l9.
  • the shaft 17 extends between two plates 20 perpendicular to it, one plate of which is visible. It is carried by the plates 2O. The latter also wear a comb 2l.
  • the plates are assembled by means of components, not shown, to form a unit which forms a carrier for the shaft l7. Therefore, the reference numeral 20 should 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 is by means of a pressure fluid in one direction and by means of a pressure spring movable in the other direction.
  • 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 (e.g. 25cm / min.) In the direction shown by arrow l5.
  • the brush l6 performs swivels (e.g. 40 / min.).
  • the swivels move in a cleaning movement (which serves 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 l4 of the cover l3 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 brush is moved through its comb by a comb 2l.
  • the unit 23 is operated in rhythm with 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 2O are pivoted counterclockwise around the support rod 22.
  • 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.
  • 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 pivoted 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.
  • the latter devices include both the control means and the drive means.
  • the immersion depth of the set of brush l6 in the set l4 of the cover l3 can be chosen as desired. This enables optimal cleaning of the l4 set and adaptation to different conditions.
  • the brush l6 After the brush l6 has started its return movement from position B, it brushes through the comb 2l, the cover plaster 26 held by it falling off, provided that this has not already fallen off during the brushing-out on the occasion of the cleaning movement from position A to position B.
  • the cover plaster is removed via a collecting container 27.
  • the comb 21 In the example shown, the comb 21 is attached to the plates 20.
  • the support rod 22 is advantageously attached 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 on the lid cleaning point C defined level. This results in the desired movement of the carrier 20 at the cleaning point C in a direction perpendicular to the set of covers up and down.
  • lids l3 of a set of lids of a revolving liner card are again shown, of which each lid l3 is provided with a clothing l4.
  • the direction of movement of the cover l3 is indicated by the arrow l5.
  • a brush l6 is in turn carried by a shaft l7 and can be pivoted back and forth about its axis l8 between positions A and B via position C, as indicated by the double arrow l9.
  • the shaft 17 is carried 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).
  • the unit 23 in turn serves to pivot the plates or the support 20 for the purpose of varying the distance of the movement path of the brush l6 from the set of covers formed by the covers l3 or from their sets 14 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. This unit is used to move the plates 20 in translational movements parallel to the longitudinal extension of the set of covers at the cleaning point C. To enable such movements, the plates 2O are provided with slots 3O. The plates 2O are from the support rod 22 and Unit 23 worn. The lid cleaning point is again the area of the brush 16 located in position C.
  • the brush l6 is therefore capable of the following movement components: Swiveling movements a, b, Movements perpendicular to the surface of the lid set c, d, movements parallel to the longitudinal extent of the lid set e, f.
  • Swiveling movements a, b Movements perpendicular to the surface of the lid set c, d, movements parallel to the longitudinal extent of the lid set e, f.
  • the movements according to components a and c are carried out at the start of cleaning movement a.
  • component f is executed and immediately afterwards the movement is carried out according to component d.
  • FIG. 3 the thick solid line shows the course of a given point of the brush 16. This is point 39 in FIG. 2, for example.
  • the clothing 14 is also shown.
  • the position 3l denotes the position of the axis l8 before the start of the cleaning movement a of the brush l6, position 32 the position of the axis l8 after execution of the movement c by means of the unit 23, position 33 the position of the axis l8 after execution of the movement f by means of the unit 29 and position 34, the position of the axis 18 after executing the two movements c and f.
  • the point 39 of the brush 16 that executes a swivel describes one of the circular paths shown, namely the circular path 35 belongs to the position 31, the circular path 36 belongs to the position 32 , 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 returned to them 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.
  • the movement f takes place while the brush 16 moves over the cleaning point C.
  • the brush l6 dips into vigorously into the set during this working phase, the immersion depth being given by the choice of the size of the movement c.
  • the speed at which brush l6 moves through clothing l4 is slowed down by superimposing component f on 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 l4 set.
  • a periodic movement of the latter through the comb 28 is provided for cleaning the brush 16.
  • the comb 28 is not carried by the plates 20 which form 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 in the position B position finds, during the cleaning movement a before the passage of the brush l6 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 l6, again in their position close to the cover at the cleaning point will.
  • FIG. 2 permits many other variants in addition to the examples shown.
  • adaptations to various conditions are possible.
