Definitions

  • the invention relates to a roller device for crumbling stripes of carcasses of worn tires and recovering steel wires, fibres and warps separated from rubber grains.
  • the present invention seeks to provide a solution to solve in an extremely easy and complete way the problem of crumbling and separating wires from warps in only one
  • the material is moved by rotating surfaces.
  • the device essentially consists of two rollers each having a side edge or shoulder.
  • the two rollers with the relative edges are juxtaposed to each other with parallel axes so as to form a nip or a passage 20 - between each other having a rectangular section closed at .. the four sides of the rectangle. If a stripe of the carcass of a worn tire is inserted between the two rollers and if for example the upper roller is rotated, the stripe is confined between the two side edges or 25 shoulders so that its thickness is considerably reduced, and due to the high pressure the stripe is then crumbled in grains. Also the steel wire and the warps are separated from the wrapping rubber due to such considerable pressure and the different elasticity of the TM materials.
  • _ 9 ___ crumbling is a granular material containing small pieces of steel wires, warps or loose wires or fibers and rubber grains of different size. By easily separating the three mentioned materials obtained by crumbling stripes of worn tires, it is possible to recover the three materials at low cost and to use them again for industrial purposes. As many pairs of rollers as desired can be provided in a crumbling machine for the treatment of stripes of worn tires, the distance between the axes of the two rollers being chosen according to the granulometry desired by the user .

  • Fig. 2 is a longitudinal section view along the line A-A of Fig. 1;
  • Fig. 3 is a detail of the compressed material in which the uniform distribution of the load all over the periphery can be seen;
  • Fig. 4 shows a variant in which balls projecting from the counteracting plane are provided;
  • Fig. 5 is a front view of a second embodiment of the Invention:
  • Fig. 6 is a side view of the embodiment of Fig. 5>
  • 1 - compression roller provided as a whole with two shoulders 1A and IB of such a diameter as to be placed upon or cover the edges of plane 2 ;
  • roller 1A and IB - side shoulders of roller 1 having the function of avoiding that material 3 can be laterally discharged during the compression between the body of roller 1 and the counteracting plane 2 ;
  • Fig. 1 shows the main section of the device of the present industrial invention from which the form of the compression roller provided with two shoulders 1A and IB having a diameter such as to cover the short sides of the counteracting plane 2 can be seen.
  • Material 3 i.e. the stripes of worn tires, is forced by the rotation of roller 1 in the direction of arrow 5 to pass between roller 1 itself and plane 2 while being sideways confined between shoulders 1A and IB. Therefore, a strong, as high as desired, compression is provided which is above all evenly distributed on the four sides of material 3 -
  • Such compression causes a complete crumbling of the rubber and the removal of foreign bodies, as already described, i.e. lengths of warps, threads and steel wires, all of them well separated from the rubber.
  • Fig. 2 shows a number of balls like those of Fig. 1 having the function of carrying out different compressions of the material during the movement of the latter in the direction of the two arrows, such different compressions being carried out by progressively reducing the passage section.
  • Fig. 2 shows in particular the reduction of the gap P between compression roller 1 and the counteracting plane 2 as the materials move to the output of the device.
  • PI is larger than P2 and so on up to PN which is the smallest gap among all sections.
  • the pieces produced by the crumbling action of roller 1 and plane 2 i.e. lengths 7 , rubber grains 8 and warps or threads 9 , are shown.
  • Fig. shows the compression section where arrows 10 indicates the uniform distribution of the compression load along the periphery of the section, such load causing the rubber to be completely crumbled and the threads, fibers, warps and broken steel wires to be removed.
  • Fig. 4 shows a number of balls placed along a line parallel to a generatrix of roller 1 in the compression section and projecting upwards from plane 2.
  • the balls designated in that figure by 11 are inserted from the lower side of plane 2 and held in their positions by a generic cover 12. Balls 11 cause the material to move at uniform speed along the restricted section so that also the compression of the processed material is in that case practically uniform. Otherwise, if balls 11 are not provided, material 3 is also subjected to a tensile stress perpendicular to the section of Fig. 3 and due to the contact between material 3 and stationary plane 2.
  • roller 1 and plane 2 The effect of such tensile stress due to the slippage of the material on plane 2 promotes the removal of the foreign bodies from rubber . - Therefore a combination between roller 1 and plane 2, and between roller 1 and balls 11 assures a final result of very good quality and provides as end product nearly clean steel wire lengths, rubber grains of different (in any case very small) size, and warps or the threads thereof well separated from the rubber.
  • the gap (PI, P2, ... PN) is not a determinant feature of the system formed of roller 1, shoulders 1A and IB and the counteracting plane 2 with or without balls 11. Determinant are, however, the two shoulders 1A and IB which have to enclose the restricted section at the sides of plane 2 in order to allow the stripes of the worn
  • Figs. 5 and 6 can be applied also in combination with the assembly formed of roller and stationary plane in order to shorten the processing time.
  • the same numerals designate the same components as in the preceding embodiment.
  • the stationary plane is replaced by a second roller 2' rotatable about its own axis, and each roller i s provided with an edge or shoulder 1A and 2A. respectively.
  • the two rollers rotate in the direction 'of arrow 5 . thus causing a stripe of tire to be compressed and the section thereof to be reduced.
  • Numerals 3 indicates the materials to be crumbled and also the small section between the two rollers 1 and 2' between which the maximum compression according to arrows 6 takes place. Such compression is perpendicular to the four sides of section 3 so that no elastic recovery typical of such materials is given.

  • Fig. 6 shows a general side view illustrating the effects of the particular machining, i.e. the end products 7 , 8 and 9 of the crumbling of worn tires.
  • PI i.e. the minimum gap between rollers 1 and 2'
  • it is necessary to point out that such gap may be varied as a function both of the number of rollers which have to be mounted in a crumbling machine and above all of the desired granulometry of the rubber at the end of the crumbling operation.

Abstract

Dispositif constitué d'un ou plusieurs cylindres pourvus des deux côtés de bords ou d'épaulements appropriés (1A), et adaptés pour tourner autour de leurs propres axes afin de comprimer et de broyer les pneumatiques usés sous forme de bandes, en les serrant contre un plateau immobile (2) écarté de la tangente au cylindre (1) parallèle audit plateau (2). Ledit plateau (2) est éventuellement muni d'une rangée de billes (11) au niveau de l'écartement entre le cylindre (1) et le plateau (2). Afin d'augmenter la vitesse de fonctionnement, le plateau immobile peut être remplacé par un second cylindre opposé au premier et parallèle à celui-ci, et apte à tourner autour de son propre axe. Chaque cylindre ne possède qu'un seul épaulement latéral fermant l'écartement entre les deux cylindres sur un seul côté, l'autre côté étant fermé par l'épaulement du cylindre opposé. Grâce à cette compression, on récupère la totalité des granulés de caoutchouc, que l'on peut séparer des câblés acier et des fils de chaîne des pneumatiques usés.
