Definitions

  • the present invention relates to a method for grinding card clothing according to the preamble of patent claim 1.
  • the grinding device for performing the method is characterized by the features contained in claim 2.
  • the card shown in FIG. 1 comprises a breeze 11, which transfers the textile fibers supplied to it to a reel 12.
  • the carding takes place between the reel 12 and a revolving cover chain 13.
  • the latter is guided over deflection rollers 14.
  • the resulting fleece is handed over to the customer 15 and passed on by the latter.
  • the direction of movement of the elements mentioned is indicated by arrows.
  • 13 teeth which form sets 16, 17, 19 and 18, are attached to the cylindrical lateral surfaces of the elements 11, 12 and 15 and to the surfaces of the individual covers of the element directed against the drum 12.
  • These sets can consist of fixed teeth or teeth that form a flexible set.
  • At least one or some or all of the sets 16 to 19 are continuously subjected to a grinding operation during operation.
  • the abrasives can be designed in different ways. Some examples of such embodiments are shown in FIGS. 2 to 5.
  • FIG. 2 The example of the abrasive of FIG. 2 is explained on the basis of the element formed by the reel 12. This figure shows only part of the reel 12 and the clothing 17. The axis of rotation of the reel 12 is perpendicular to the plane of the drawing and is located outside of FIG. 2.
  • the reel 12 is covered with a reel cover 21.
  • An abrasive 48 comprises an abrasive material 22 designed as a grindstone, which is carried by a carrier 23 with a ball joint 24.
  • a guide body 25 provided with a thread and a rotary knob has a cylindrical opening 26, in which the carrier 23 is slidably mounted.
  • the guide body 25 is screwed onto a slide 27, which can be moved back and forth along rails 28 in the direction perpendicular to the plane of the drawing.
  • the rails 28 are formed by angled strips, which are provided on the edges of the side walls 29 remote from the set 17.
  • the side walls 29 are rectangular, elongated in shape. They run parallel to one another, and their longitudinal edges are parallel to the axis of rotation of the spool 12. The longitudinal edges of the walls 29, which are removed from the rails 28, are in the immediate vicinity of the clothing 17.
  • a compression spring 30 is attached between the guide body 25 and the grindstone 22, which compresses the Grindstone 22 against the set 17 is biased and strives to position it in its elastically biased, predetermined position shown in FIG. 2.
  • This bias generally exerts a very light pressure of, for example, 10 to 20 grams. This pressure can be adjusted by turning the rotary knob of the body 25.
  • the grindstone 22 is held movably by the ball joint 24.
  • the reel 12 is in constant rotation, and at the same time the slide 27 and thus also the guide body 25 with the carrier 23 and the stone 22 are continuously moved back and forth along the rails 28.
  • the teeth of the clothing 17 are subjected to a grinding operation during operation, and thus the interruptions in operation mentioned above for grinding the teeth and the periodic changes in the sharpness of the tooth tips are eliminated.
  • a movement of the grinding area 31 of the grinding material 22 is possible essentially in the direction of movement of the clothing and in the direction perpendicular to it, parallel to the axis of rotation of the drum.
  • the carrier 23 slidably mounted in the opening 26 allows the grinding area 31 to move in a direction perpendicular to the clothing 17 on the grinding area 31.
  • a movement of the grinding area 31 in three mutually perpendicular directions is thus possible, ie the grinding area 31 has three degrees of freedom of movement and therefore adapts to irregularities in the clothing surface defined by the tooth tips during grinding.
  • the aim is to design the set 17 in such a way that all tooth tips are at exactly the same height, i.e. that they define a precise circular cylindrical surface, the axis of which coincides with the axis of rotation of the drum.
  • the deviations can in particular consist of zones of relatively large and relatively small peak heights. Thanks to the three degrees of freedom inherent in stone 22, the stone adapts to these irregularities, which means that all teeth are ground to practically the same degree.
  • the application of the abrasive 48 shown in FIG. 2 is not limited to the reel. Such an abrasive 48 can also be used on the breeze 11, on the revolving cover chain 13 and on the customer 15.
  • the drum 12 is equipped with a drum cover 21.
  • the abrasive 48 In order to enable the abrasive 48 to be installed, as shown in FIG. 2, this must have an open area which extends in the axial direction over the entire assembly 17. Abrasive 48 is placed airtight above this. So that the means 48 itself is also airtight, on the one hand the walls 29 provided with end walls (not shown) attached to their ends and perpendicular to their longitudinal direction.
  • the carriage 27 is driven with a drive belt, not shown, which covers the open part located between the rails 28 and removed from the drum 12.
  • Each of the rails 28 is provided with a longitudinal slot 50, in each of which a longitudinal side of the drive belt is slidably mounted.
  • the walls 29 with the end walls mentioned, the drive belt and the slide 27 form a trough-shaped structure which is self-contained on the outside against the clothing 17.
  • the grindstone 22 is continuously moved back and forth over the clothing. If this lateral movement is not desired, an abrasive according to FIG. 3 or FIGS. 4 and 5 extending in the axial direction over the entire set can be provided.
  • the abrasive 32 comprises a trough-shaped receptacle with two side walls 33 and a cover plate 34.
  • the free edges 36 of the walls 33 run parallel to the abrasive 32 lying against the revolving cover 35 or perpendicular to the direction of movement of the clothing 18 attached as a flexible band bracket 37 which extends in the longitudinal direction of the cover 35 (perpendicular to the plane of the drawing) over its entire length.
  • the carrier 37 On its side facing the revolving cover 35, the carrier 37 has an abrasive coating which, for example, consists of fine abrasive particles, in particular diamond powder.
  • the carrier 37 can be, for example, a metallic thin strip, a fabric or plastic with an abrasion coating, which adapts to the local irregularities, ie the geometric shape of the surface defined by the tooth tips of the clothing, but is not deformed by the grinding forces. In addition, it must not form folds.
  • the hose 38 can be filled with a fluid of the desired pressure through a valve 39.
  • the hose 38 thus exerts the same pressure at every point on the carrier 37.
  • the carrier 37 is thereby pressed over its entire length against the cover 35 and therefore lies evenly on the clothing 18 with its abrasive coating.
  • the zones of the carrier 37 moving into an elevation or depression can only execute their movement if zones adjacent to these zones simultaneously execute movements which have a movement component parallel to the carrier 37, ie horizontal according to FIG. 3 have. It can thus be seen that the possibilities of movement of the grinding surface of the carrier 37 in three mutually perpendicular directions, ie the presence of three Degrees of freedom of movement of the abrasive, an essential feature.
  • the abrasive 32 is also suitable for grinding each of the elements 11, 12 and 15.
  • each stone 41 is carried by a carrier 42 by means of a ball joint 43 and guided in a cylindrical opening 44.
  • a guide plate 46 is fastened, in which an opening 44 is made for each carrier 42.
  • a uniform prestress for the abrasive material 41 is generated by an elastic hose 47, in which a fluid is filled with a predetermined pressure.
  • each of the stones 41 in turn adapts to the irregularities occurring with regard to the height of the tooth tips, by the stones 41 correspondingly occurring raised or lowered zones pivoting by means of the ball joint 43 or because the carriers slide 42 enters openings 44. It is therefore In this example, too, there are three degrees of freedom of movement for each grinding area of stones 41.
  • the movement of the revolving cover chain 13 is relatively slow. If the grinding effect is insufficient for this reason, this can be the case if grinding stones are used, e.g. 2 or Fig. 4, 5, can be increased by additionally setting the stones in oscillations or vibrations. Of course, the grinding effect when using a hose 38 or 47 can also be varied by the variations in the pressure present therein and by vibrations thereof.
