  • the purpose is to solve the problem which is found in the known screens with selector discs, when urban or heterogeneous waste is to be treated; said problem is due to the fact that the light, long and more or less flexible bodies, such as threads, ropes, rags, plastics, paper, or similar or like products, etc., are twisted around the axes, which provide motion to the rollers, clogging them and reducing the sorting capacity until it is eliminated.
  • the known solution provides making a screen in which discs of polygonal shape are used, which peripherally have lateral, axial or inclined extensions, normally placed on both sides.
  • the known solutions have, around the selector shafts, cylindrical tubular elements or cylindrical sleeves, free to rotate independently with respect to the aforementioned shafts.

  • a disadvantage of the known solutions is given by the fact that the cylindrical sleeves, having a circular section, are also brought into rotation by the shaft on which they are installed due to the friction which is generated between the shaft and the cylindrical sleeves weighed down by the material to be treated acting thereon.
  • the cylindrical sleeves rotate together with the shaft, they carry with them any elongated flexible elements such as wires, rags, paper and plastic sheets, etc, which tend to twist, creating tangles which, in order to be removed, require stopping the machine and cutting with cutting devices such as grinders or similar.

According to such a document, the spacer elements can rotate even if for a limited stroke with respect to the shaft, whereby do not solve the problems indicated above.
  • EP1358020B1 , EP3771499A1 , US8646615B2 and EP3922356A1 describe other known selector devices.
  • One purpose of the presente invention is to make a separating sorting machine that is able to prevent the generation of lacings in the material to be treated that could obstruct the discharge gaps between the rollers and prevent the functioning thereof.
  • Another purpose is to prevent material from being twisted on the tubular elements.
  • One purpose of the present invention is to provide a separating sorting machine which tends to provide a greater guarantee regarding the quality of the sorting, at the same time it tends to obtain a better yield in terms of productivity for the improved drawing capacity of the material to be sorted by the discs themselves.
  • Another purpose of the invention is to provide a separating sorting machine suitable for also treating pre-milled or chips of fresh or recycled wood, which must be sorted by thickness or, even, by reasonable length.
  • Yet another purpose of the invention is to eliminate the need to provide weights, tending to avoid the rotation of the tubular elements, placed covering the rotating shaft, that would prematurely wear out the tubular elements.
  • the technical problem that the invention wants to solve consists in creating a simplified separating sorting machine with discs which is suitable for screening urban solid waste as well as other materials similar thereto, identified above by way of example.
  • a purpose of the invention is to improve the drawing effect of the material to be treated, normally avoiding filiform or similar and/or long, flexible and light, or the like, products from being wound around the selector shafts.
  • Yet another purpose of the invention is that of strongly reducing, or rather eliminating, unwanted stops of the machine, for example those for twisting or clogging.
  • the present invention concerns a perfected separating sorting machine, suitable for treating heterogeneous products, coming from the most disparate sources, in order to obtain the desired separation of the components present in the material to be treated, said separation operation being finalized for the specific use.

  • the element preventing the rolling is preferably autonomous, i.e., it is not connected to the rotating shaft and/or to the selector discs.
  • the lying plane of the axis of the rollers does not necessarily have to be horizontal, i.e., everything lying on the same plane.
  • the sorting plane may also be inclined, or can have one or more steps; said steps may be horizontal, i.e., all or part may be inclined in the feed direction.
  • the present invention further provides that the tubular, anti-clogging elements, present idle on the disc-holder shafts, and between one selector disc and the other, have an oval shape, advantageously but not necessarily, coordinated with the section of the shaft.
  • the tubular elements substantially enclose and protect the free part of the rotating shaft arranged between two successive selector-drawing discs.
  • said tubular elements have a hollow oval section defining a housing compartment for said rotating shaft, in which said housing compartment is configured to allow a vertical oscillation movement of said tubular element with respect to said rotating shaft.
  • the oval section of the tubular element and of the housing compartment is configured so that when the rotating shaft is inserted in the tubular element, a free space remains between an internal wall of the tubular element and an external surface of the rotating shaft which allows an oscillation, i.e., a vertical movement of the tubular member.
  • the oval shape prevents twisting, as it does not rotate while it lets the long, light, flexible and/or threadlike, or similar elements slip.
  • the selector discs have widths suitable for the purpose from time to time; they do not have the axial, or inclined, extensions placed on both sides of the drawing discs as in the known solutions which create problems in many operating situations.
  • the discs peripherally have from three to nine or more peripheral walls having flat or substantially flat surface as a whole, not necessarily uniform, which define a polygonal shape of the discs.

  • peripheral presence of flat surfaces, or substantially flat in the set of one or the other of the possible embodiments identified above, improves the drawing and sorting effect of the selector-drawing discs; this is because also said surfaces, with the wall function they perform, contribute to the drawing and to the interference action with the material and thus the sorting.
  • at least one of the lateral walls is orthogonal to the rotation axis.
  • At least one of the lateral walls advantageously has an angle with respect to the rotation axis, an angle which can be even a few degrees, possibly also placed in a negative direction, thus avoiding jamming and improving the sorting effect.
  • At least one surface of a peripheral wall of at least one selector disc may have, according to the material to be treated, more or less rounded shapes in various ways, i.e., cusp-shaped, i.e., with more or less accentuated undulations.
  • the selector discs have the periphery shaped like a polygon, advantageously, but without limitation, the solution with seven sides is considered preferable, which is the one most used in relation to the average material to be treated and the average result required, on the filing date of the invention.
