Definitions

  • the present invention relates to a removal roller for the mechanical opening and removal of fiber bales by loosening fiber flakes from the same by means of a rotatable shaft attached to it, circular toothed disks attached to it, which are provided with teeth over their outer circumference.
  • a bale grater has become known, according to which rotating sawtooth disks which advance between rust bars against fiber bales passed on them, tumbling, ie. H. at an angle other than 90 degrees with respect to their axis of rotation.
  • the washers are located on a shaft and are pressed in between spacers by means of tension bolts.
  • each of the toothed disks comprises two half disks, which essentially have the shape of a half circular ring, that an approximately semicircular shell is provided for each half disk, that each half disk is cast into one shell each, and that the shells are self-contained to form a toothed disk, half-disks enclose the shaft in a ring shape, releasably attached to one another and firmly connected to the shaft by a press fit.
  • toothed disks can be rotated into any desired position.
  • the roller according to the invention has the additional advantage that such vibrations can be easily eliminated or greatly reduced.
  • pouring the half disks into the shells also allows the selection of the most suitable material for each of these parts within wide limits. It is z. B. possible to keep the weight of the shells small by making them from a light material, and to manufacture the teeth and / or toothed lock washer from a material of great hardness in order to obtain a long life for them.
  • the removal roller 11 shown in FIG. 1 has a shaft 12, which is also shown in FIG. The latter is rotatably supported at its two ends in bearings 13, which in turn are mounted on carriers 14.
  • the shaft 12 is also driven by means not shown for rotation.
  • Each disc comprises two half discs 15 and 16 lying in one plane.
  • the half disc 15 is cast into a shell 17 and the half disc 16 is cast into a shell 18.
  • the two shells 17, 18 surround the shaft 12 in an annular shape, but, like the half disks 15, 16, are separated from one another by slots 21.
  • the shells 17, 18 are detachably fastened to one another by screws 22, pressed firmly onto the shaft 12 and in this way firmly connected to the shaft 12 by a press fit.
  • Each of the shells 17, 18 comprises a jacket 27 (FIG. 2) which, apart from the minimal deviation caused by the slot 21, has the shape of a half cylinder and ribs 23 are attached to the inside thereof.
  • the jacket 27 is provided with indentations 28.
  • the disks, each consisting of a half disk 15, 16, are arranged perpendicular to the shaft 12. However, if this is desired, they can also be inclined at an angle a with respect to the shaft 12, as is shown by the disks 15a and 16a shown in broken lines.
  • the shaft 12 is a multitude of such pairs of half disks 15, 16 and shafts
  • the shells 17, 18 abut one another.
  • FIG. 3 a single half disk 16 is shown for further illustration.
  • the half disks 15, 16 have essentially the shape of a half circular ring. They are provided with teeth 24 on their outer circumference.
  • Each of the half disks 15, 16, apart from the removal caused by the slits 21, is cast into the associated shell via a half circular ring which extends outward from its inner circumference to the imaginary half circle 25 (FIG. 3).
  • the semicircle 25 coincides with the outer surface of the shell 27 of the shell 17 and 18 respectively.
  • the shaft 12 and thus the disks comprising two half disks 15, 16 are also set in rotation.
  • 24 fiber flakes from the z. B. on the rust bars 26 pressed fiber bales. These flakes are continuously sucked off and conveyed for further processing.
  • the fiber bale can e.g. B. are constantly pushed back and forth along the grate bars 26, the rotation of the shaft 12 taking place in one or in the opposite direction of rotation, depending on the direction of displacement. If the disks are in an inclined position, as shown by the half disks 15a and 16a, then they wobble. Movement out. Therefore, practically the entire area between two adjacent grate bars 26 is covered by each pane.
  • the corresponding pair of half-disks 15, 16 with the shells 17, 18 is removed by loosening the screws 22 to remove the damaged tooth. having unit half disc shell removed from the shaft 12 and replaced in its place a new unit. This is carried out without having to dismantle the shaft 12 and having to move a little forward on the other half disks and shells located on the shaft 12. The same procedure can also be used for the normal wear of the disk pairs 15, 16.
  • Hard teeth can be obtained, for example, by using half discs 15, 16 made of steel, which are hardened at the location of the teeth 24.
  • an area of the half-disks 15, 16 adjacent to the latter, which extends from the teeth to the imaginary semi-circle 25 (FIG. 3), or the entire half-disk can be hardened.
  • the shells 17, 18, as is the case in the example shown are designed as non-solid elements. To reduce weight, they are made from aluminum in an advantageous embodiment.
  • the material from which the disks and shells are made can be selected largely independently of one another.
  • the disks can be made from steel and the shells from aluminum.
  • the half-disks 15, 16 are advantageously poured into the shells 17 and 18, respectively, by pressure or injection molding. If a particularly firm connection of the half disks to the shells is desired, then configurations designed for this purpose, such as bores or small elevations, are provided on the half disks. Such bores 29 are shown in FIG. 3, for example.
  • the shells 17, 18 are adapted to the spacing of adjacent grate bars 26, i. H. that their extension in the longitudinal direction of the shaft 12 is equal to the division of adjacent bars 26. By the abutment of the shells against one another, an additional strength of the roller is obtained, so that a possible provision of spacers between joined pairs of shells 17, 18 8 is unnecessary.
  • the pairs of shells 17, 18 can, however, also have mutual distances from one another in the longitudinal direction of the shaft 12 (not shown).
  • dashed lines show a staggering of disks in which the teeth of adjacent disks are staggered radially by an amount which in this case is equal to a quarter of the distance between adjacent teeth 24 of a disk.
