Definitions

  • the invention concerns: a diamond roller for ceramics, having abrasive with sloped side, that is an utensil of working of ceramic material, typically the hard-fired ceramic in tiles, for the grinding and/or calibration of the surface in sight of the tiles.
  • the state of the art comprises varied types of diamond abrasive rollers with most varied conformations of the abrasive disposed with sectors or teeth on parallel lines to the generating line of the roller, on spiral or helixes to varied conformation also multi starts, beyond to the rollers with abrasive disposed without solution of continuity on all surface of the roller.
  • Machines are present in the state of the art as grinding machines and/or calibrating machines , like disclosed in the application of European Patent EP 769349 Al , in which said rollers present the generating line tilted as regards the perpendicular direction to the direction of the motion of the material in working, to adjust in a rapid way the width of the front of cut to the width of the material to work .
  • the aforesaid calibrating machines with tilting rollers when used in the working of the ceramic material, present drawbacks in the zones of start and stop work of the generating line of cut from the surface of the tile: in fact, in the begin the working on the tile the roller present yourself with a vertex of his generating line in such a way to assure for a brief time, till that the tile not has advanced of a sufficient amount of length, on said zone of start work so that remove more than the necessary from the surface of it; in a following moment, when a bigger roller portion is in working on the tile, this abnormal removal no more happens, because the uniform distribution of the pressure of the roller on a bigger length of the generating line; likewise in the moment of stop work of the roller from the surface of the tile is verified an analogous bigger removal .
  • the present invention solves the above-mentioned technical problem by adopting: a diamond roller for ceramics, having abrasive with sloped side, comprising the abrasive diamond material disposed on the surface of the roller, characterized from that, it presents for a brief length and on one end, at least, of the envelope surface of the abrasive, with decrease of height from the diameter of cut to the diameter of the roller.
  • Adopting moreover: said decrease of height of the abrasive with constant inclination.
  • Adopting moreover: said decrease of the height of the abrasive present on both ends of the roller.
  • Adopting moreover: the diamond abrasive disposed in a discrete way, that is with sectors or teeth, on the surface of the roller.
  • Adopting finally: said sectors or teeth disposed according to a multi starts helix.
  • the begin start work of the roller happens in a gradual way and the bigger removal, located in the zones of start and stop work of the generating line from the surface of the tile, not happens, not even with the rollers with diamond sectors or teeth arranged to helix, also if the sector or tooth of cut presents the axle parallel to the direction of advance motion of the tiles .
  • Figure 1 is the perspective schematic view of the tiles in working with an abrasive roller to tilted axle, with the sloped sides according to the invention
  • Figure 2 is the side view of a roller with abrasive disposed on multi starts helix
  • Figure 3 is the transversal view of the roller of Figure 2.
  • the indications are as follows: with 1, Figure 1, the line of tiles 2 in ceramic material, having advance motion in the direction A; with 3 the tiles in working; with 4 the tiles worked and 5 the stop work zone of the abrasive roller and 6 the start work zone of the working; with 7 the zones of stop work of the working in the tiles in wor- king; with N the perpendicular direction to the direction of the motion A; with C the direction of the generating line envelope of the sectors or abrasive teeth 8 of the abrasive roller 9, in contact with the surface of the tile; with B the angle formed between the generating line C and the perpendicular direction N; with 10 the sloped sides of the abrasive on the roller 9.
  • indications are as follows: with 11, Figure 2, the line of the generating line envelope of the sectors or abrasive teeth of the roller 9; with 12 the conical sloped sides of said generating line envelope in the end zones the roller, to which the sectors or abrasive teeth are conformed; with 13 , Figure 3 , the inside diameter of the roller for the joining to the relative shaft; with 14 the axial holes of fixing said roller on said shaft.
  • the operation of the diamond roller with sloped sides of the abrasive happens like as follows: the roller 9, is positioned with the correct angle B for the working of the width of the tiles 2, as known with dimension slightly lo- were of the same width; the tiles are made advancing with the roller in rotating motion on the own axle to the recommended cut speed; in the above mentioned zones of start work 6 of the cut of the diamond abrasive roller on the surface of the tile 3 , the presence of the sloped side 10, 12 allows a gradual beginning so that don't remove the material in concentrated way ; likewise in the zones of stop work 5 of the cut of the sectors or teeth 8 of the roller, it happens in a gradual way so that doesn't let witness marks .
  • the roller could present the degrading sloped sides 10, 12 of the abrasive from one end only, being known that the rollers could be composed in an axial way, and in the case they could be composed specularly in the middle on the same head of calibration, reaching the combined effect of graduate as the start work as the stop work of the cut of the roller on the tile 3 , as the roller 9 with the sloped sides 10, 12 from both ends .
  • the diamond abrasive even if less suitably, could be disposed in uniform and continuous way on the surface of the roller, also presenting a sloped side of the thickness of it, at least.
  • the decrease of the height 12 of the abrasive by making the sloped side, could not be at constant inclination that is to conical conformation 10, like represented in the Figure 2 , but made with rounding it at constant radius or varying radius .

Abstract

Un rouleau (9) diamant pour céramiques, dont l'abrasif présente un côté oblique, comprend un abrasif diamant sur sa surface et se caractérise en ce qu'il présente sur une petite longueur (10) et sur une extrémité, au moins, de la surface d'enveloppe (11) de l'abrasif, une réduction de hauteur (12) du diamètre de coupe au diamètre du rouleau. Ledit côté oblique (12) présente une inclinaison avantageuse et se trouve sur les deux extrémités du rouleau. Pour conclure, les marques de repères de début (6) et de fin (5) de travail du rouleau sur la surface carreau (3) sont absentes même lorsque l'abrasif diamant est placé dans des zones ou sur des dents (8) situées sur une hélice à plusieurs filets.
