Definitions

  • the present invention relates to a modular roller for industrial rotary cylindrical brushes, particularly for outdoor use.
  • large cylindrical brushes which have bristles up to 30 centimeters long, may have a length on the order of approximately two meters long, and are mounted and actuated so as to rotate about a horizontal axis for cleaning, for example, courts, roads, squares, industrial buildings or the like.
  • Brushes are also known which are constituted by a plurality of rings meant to be assembled by packing them side by side, optionally with spacers interposed, on a central tubular core: said rings have bristles that are usually arranged at right angles to the rotation axis (radial direction).
  • the radial arrangement of the bristles produces dirt release regions between the contiguous rows of bristles; owing to the linear motion of the roller on the ground, said regions take the shape of narrow elongated streaks of dirt.
  • DE-U9309920 discloses a brush having a combination of featueres as set forth in the pre-characterizing portion of the appended claim 1.
  • the aim of the present invention is to obviate the cited drawbacks and to meet the mentioned needs, by providing a modular roller for industrial rotary cylindrical brushes, particularly for outdoor use, that does not leave streaks of dirt on the ground, energetically removes dirt also by means of lateral motion components, can be fitted with filaments of different types and materials, works without requiring intense pressures, and therefore has a low wear and reduces the stresses affecting the mechanical parts.
  • an object of the present invention is to provide a structure that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
  • the reference numeral 1 generally designates a modular roller for industrial rotary cylindrical brushes, particularly for outdoor use, according to the invention.
  • the roller 1 is of the type that comprises a central support 2 which is produced by molding or extruding material such as plastics and has a cylindrical tubular shape and a maximum thickness of approximately thirty millimeters; the rollers are keyed on a driving shaft A which can rotate substantially horizontally, and in relation to this, for example, in a planned embodiment the central hole of the support has at least one radial slot for rotationally rigid coupling to a corresponding external longitudinal coupling rib of the shaft A.
  • the faces 3 and 4 of the support are cut along two mutually parallel planes, which are inclined, with respect to planes that are perpendicular to the direction of the axis a of the cylindrical ring, by an angle B between zero and thirty degrees.
  • the reference numeral 5 designates tufts of bristles, which are distributed along the ring and lie on planes that are substantially radial to the ring and parallel to the inclined planes of the bases 3 and 4; in particular, the tufts can be actually radial or parallel to a radial plane r but slightly offset by a short extent therefrom (see Figure 4); with this distribution of the tufts of bristles, if the roller is actuated in the direction of the arrow B, a sort of gentle sweeping of the ground is achieved, whereas rotation in the opposite direction has a stronger scraping effect on the ground; the tufts 5 have an end that is inserted and retained by means of a metallic staple or glued or hot-welded in a corresponding radial hole 6 of the support.
  • the tufts of bristles are made of a material such as polypropylene and/or nylon and/or polyester and/or metal, and can be distributed in the holes with different characteristics, alternating tufts of a certain material with tufts of a different material: the tufts can also be made of bristles having multiple diameters and/or made of multiple different materials: it is possible to alternate on the shaft A rollers provided with bristles and spacer rollers 7, which are also oblique and have no bristles.
  • the width of the support 2 may be any and may even cover the entire length of the brush, and the holes for the tufts can be distributed on any number of rows and can be mutually aligned or staggered.
  • two end heads 8a and 8b are fixed to the shaft A at the beginning and at the end of the pack of rollers 1; such heads are constituted by tubular bodies, in which one face 9 is inclined for resting against the outer rollers of the pack and the other face 10 is flat and provided with means for locking their rotation and longitudinal sliding with respect to the shaft A (optionally, said means can be constituted by radial screws inserted in corresponding radial holes 11 of the heads or also by front screws).
