Definitions

  • the present invention relates to a machine for cutting slabs of stone or stone-like material.
  • the present invention relates to a machine suitable for cutting slabs of rigid material, such as natural stone, composite stone, glass and ceramic material.
  • These machines generally comprise one or more machining units which move within a working volume.
  • the machining unit is moved inside the working space in various ways including, most frequently, it has a structure provided with two lateral support structures which may be made of brickwork and above which a beam moves, said beam resting with its ends on top of the lateral support structures.
  • the machine also comprises a carriage which is movable along the beam and is provided with a sleeve designed to be moved along a third axis, perpendicular to the first two axes, i.e. in a vertical direction.
  • the end of the sleeve is provided with a so-called machining head which may have a diamond-disk, diamond-chain or water-jet tool.
  • a machining head which may have a diamond-disk, diamond-chain or water-jet tool.
  • a combination of two different cutting technologies for example diamond-disk cutting and water-jet cutting, is also used.
  • These machines are equipped with systems for moving the slabs or parts thereof inside the working volume or also externally for example in order to unload finished slabs into a store.
  • a first type of movement system has a second beam which moves on the same lateral support structures as the first beam and which has a shuttle provided with sucker means which may be lowered towards the support surface.
  • the sucker means are lowered opposite the surface so that they come into contact with the slab or a portion thereof, a vacuum circuit is activated so as to perform gripping and then the raising or displacement operation is performed.
  • a second type of movement system has sucker means which are provided directly on the machining head and which can be moved with respect thereto via a pneumatic piston, so as to be able to be lowered towards the support surface, grip the part to be displaced and then raise the part and move it.
  • a third type of movement system has sucker means which are positioned on a support structure arranged alongside and which are designed to be engaged by the machining head and positioned above the element to be displaced, move downwards and grip the part and then raise the part and displace it.
  • a fourth solution has sucker means which are directly incorporated in the protection cowl of the cutting blade. In this solution the suction surface is substantially parallel to the plane in which the blade lies. In order to perform displacement of a slab or a portion thereof, it is required to rotate the machining head through 90° so that the suction surface is parallel to the surface of the slab. Then the machining head is lowered until the suction surface makes contact with the surface of the slab and a vacuum circuit is activated in order perform the gripping action. Using the means for moving the machining head the slab is raised and displaced.
  • Italian patent IT 1409412 describes a machine for cutting slabs which comprises a cutting head and a suction manipulator.

  • the arm 38 may rotate relative to the support structure 36 about an axis substantially parallel to the working surface. In this way it is possible to move the suction surface so as to change from a configuration substantially parallel to the working surface to a configuration substantially perpendicular thereto.
  • This configuration may be used to remove the slabs from a store in which they are arranged substantially vertically or to position them in such a configuration on a support alongside the machine.
  • the arm may be moved relative to the support also in a direction perpendicular to the preceding direction so as to arrange the arm at a distance from the cutting tool.

  • the movement device 24 is in the retracted configuration, i.e. the sucker means are completely retracted in the position closer to the support 36.
  • the sleeve 20 is lowered, as shown in Figure 4, towards the working surface 34 and the sucker means are extracted so that they reach the slab 14 provided on the working surface 34.
  • the sucker means may reach the slab without any movement of the sleeve, but only via the movement of the sucker means relative to the support.
  • the vacuum circuit (not shown in the attached figures, but known per se to the person skilled in the art) is activated so that gripping between the sucker means and slab occurs.
  • the slab is raised from the working surface. The raising movement may occur by means of raising of the sleeve 20, or via the actuator means which move the sucker means towards the support, or by means of a combination of the two movements.
  • the possibility of rotating the sucker means about their axis may be used to direct the sucker means before removing a slab, depending on its size and position.
  • the possibility of rotating the sucker means about their axis may be used also to redirect the sucker means after removing a slab, in order to displace it to a location and in the manner desired.
  • Figure 6 shows a step where the sucker means with the raised slab are rotated through
  • the slab movement system may be easily implemented in machines not fitted with such a system. It is in fact sufficient to arrange a support on the sleeve of the already existing machines, together with electrical and, if necessary, pneumatic connections which may be easily provided.
