Definitions

  • the present invention deals with a calibrating-polishing system for the surfaces of stone materials, ceramics, marble, granite.
  • the working process of slabs made of stone material occurs due to the effect of the mechanical-chemical action of the tool in contact with the slab when there is cooling and lubrifying fluid.
  • the mechanical action employs the combination of abrasion, bumps and cutting of a tool composed of a multitude of grains of hard material embedded into a soft matrix with progressibely decreasing sizes.
  • a combined system for calibrating and smoothing-polishing slabs made of stone material comprises a series of tool-holder heads arranged so that the slab is subjected to a mechanical action due to tools with progressively decreasing dimensional grains, starting the contact with tools having super-coarse grain, being subjected in a sequence to the action of tools of all intermediate grains, and ending the contact with tools having super-fine grain.
  • the tool-holder heads impart to the tools a cutting speed compatible with the characteristics of the tool material and the nature of the stone to be worked.
  • the tool approach with respect to the slab surface occurs in an orthogonal direction to the surface of the slab, by pressing onto the slab with a variable pressure depending on the nature of the stone to be worked.
  • the slab advances with linear motion.
  • the calibrating-polishing system provides for the combination of a transverse movement of the tool-holder heads with the linear advancement movement of the slab, in order to allow covering the whole surface of the slan in transit.
  • a calibrating-polishing system emits noises above certain values of admissible threshold.
  • noise reducing and system insulating arrangements are adopted, together with insulating the portion of system in which the occurrence of acoustic effects outside standards is greater.
  • the noise emission due to the interaction of the tool with coarse grains with the slab to be calibrated is a double problem regarding environmental hygiene and system operating reliability.
  • the system operating reliability is obtained by raising the quality and resistance standards of electronic control systems and structural components composing the machine.
  • Another approach to keep the system reliability level high is dynamically separating the portion of the calibrating system with respect to the portion of the polishing system, by using different working planes, with related conveyor belt, and different supporting structures of the tool-holder heads.
  • Object of the present invention is reducing the emissions of noises in a calibrating-polishing system without having to use sound-proofing apparata or having to uncouple the carrier structure.
  • a calibrating-polishing system 1 comprises a working plane 2 in which a carpet 4 slides, which allows the slabs made of stone material 3 to transit along direction AD.
  • a framework 5 composed of risers 6.1, 6.2, 6.3, 6.4 and fixed beams 7.1, 7.2, supports the calibrating heads 21.
  • the portion of the calibrating system comprises at least one station C1.
  • the optimum configuration provides for two calibrating stations C1 and C2 arranged in a sequence.
  • a framework 8 composed of risers 9.1, 9.2, supports beams 10.1 and 10.2 transversely oscillating with respect to direction AD, along which the polishing heads 31 are arranged.
  • the portion of the polishing system comprises at least one array of tool-holder heads P1.
  • the optimum configuration provides for two arrays of tool-holder heads P1 and P2.
  • Safety panels 11 cooperate with the calibrating portion C1 and C2, in order to comply with the safety requirements of operators of systems in the stone-working sector according to the laws in force.
  • Each calibrating station C1, C2 comprises a head 22 with big sizes, which supports a series of tool-holder spindles 23 radially arranged with respect to the rotation centre R and with the same angular pitch.
  • the tools have a cylindrical shape.
  • the head 22 continuously rotates with respect to the fixed axis of a shaft 24 perpendicular to the surface of the slab 3 and connected to the fixed beam 7.1, 7.2 of the carrier structure of the portion of the calibrating system C1, C2; the tool-holder spindles 23 rotate at a speed corresponding to the peripheral cutting speed Vp compatible with the characteristics of the material of the slab 3 to be calibrated.
  • Each polishing station P1, P2 comprises an array of heads 31 characterised by a vertical approach assisted by hydraulic pressure transmitted by a compressed-air system.
  • Each head comprises a series of spatula-type tools having a tangential oscillating movement with respect to the plane of the slab 3. Heads equipped with cylindrical tools having a continuous tangential movement can be a variation in the configuration of the portion of the polishing system P1, P2.
  • the portion of the calibrating system made with a central head 22 connected to a series of tool-holder spindles 23 radially arranged with respect to the rotation centre 24 allows satisfying the objective of balancing the cutting forces through a distribution of the slab-tool contact along the whole transverse side of the slab 3 with respect to the advancement direction AD.
