Definitions

  • the present invention relates to a displacing apparatus for a tool holder assembly of a machine for working block or slab materials, particularly, but not exclusively, stone materials, such as, for example, marble and granite.
  • the invention also relates to a machine for working block or slab materials comprising such displacing apparatus and to a method for working block or slab materials to be carried out by said machine.
  • displacing apparatus is used to indicate an apparatus adapted to determine any movement of a machine part, either translational or rotational.
  • working is used to generally indicate any operation performed on the material, such as, for example, cutting, squaring, or shaping.
  • Machines for working block or slab materials in particular stone materials, essentially comprise a table defining a work surface on which the block or slab to be worked is placed, a tool holder assembly to which a working tool is associated, a displacing apparatus for the tool holder assembly and a command and control unit provided with a suitable operator interface.
  • a plurality of supply lines for example for power supply or for supplying a cooling fluid at the working tool, is connected to the tool holder.
  • the displacing apparatus is mounted on a horizontal gantry resting on wall supports or other vertical support structures .
  • the gantry can be moved along the respective support structures and the displacing apparatus can be moved along the gantry.
  • the displacing apparatus and the tool holder assembly can be displaced parallel to the work surface along two displacement directions X and Y, perpendicular to each other.
  • the displacing apparatus can displace the tool holder assembly along a further displacement direction Z perpendicular to the work surface.
  • the table can be rotated about an axis perpendicular to the work surface, so that the piece of material to be worked can be presented to the working tool according to different angles.
  • the need of a rotatable table involves a complex construction.
  • the displacement devices and the angular position control devices of the table usually lie under the work surface and for this reason operate under unfavourable conditions, both because they have to withstand considerable weights, and because they are constantly invested by working dust and by cooling liquids used during working operations.
  • the use of a rotatable table slows the working times because of the considerable rotational inertia caused by the weight of the table and of the material placed on it.
  • the technical problem underlying the present invention is therefore to provide a displacing apparatus for a tool holder assembly of a machine for working block or slab materials that allows to carry out complete, i.e. 360°, rotations of the tool holder assembly about an axis perpendicular to the work surface, while at the same time preventing inadmissible torsional stress on the supply lines connected to the tool holder assembly.
  • the invention in a first aspect thereof, relates to a displacing apparatus for a tool holder assembly of a machine for working block or slab materials, said tool holder assembly being rotatable about a rotation axis perpendicular to a work surface of said machine, comprising: - a shaft supporting, at a first longitudinal end thereof, said tool holder assembly, and at least one supply line connected to the tool holder assembly, characterised in that said at least one supply line comprises a portion exceeding the length of said shaft, and in that a storing space adapted to removably receive said exceeding portion is associated with said shaft.
  • the structure of the displacing apparatus of the present invention advantageously allows to make the rotation of the tool holder assembly independent from the at least one supply line connected thereto, so that it is possible to carry out even a 360° rotation of the tool holder assembly, without causing inadmissible torsional stress on the at least one supply line.
  • the exceeding portion of the at least one supply line housed in the storing space performs a "reservoir" function allowing the at least one supply line to follow the rotation of the tool holder assembly by means of a variation of the available length.
  • the total length of said exceeding portion can be chosen so as to allow compensation of a complete rotation of the tool holder assembly or just of a part thereof.
  • the at least one supply line follows the rotation of the tool holder assembly partly by recalling the exceeding portion from the storing space, partly, as in the displacing apparatuses of the prior art, by means of a torsion about the rotation axis, which, in any case, remains within admissible limits.
  • the displacing apparatus is adapted to allow the tool holder assembly to carry out rotations about said rotation axis of at least 360°.
  • the shaft supporting the tool holder assembly is rotatable about the rotation axis of the tool holder assembly and the latter is rotatably integral with the shaft.
  • the storing space is provided at a second longitudinal end of the shaft opposite said first longitudinal end.
  • the shaft is hollow and the at least one supply line between the storing space and the tool holder assembly is housed inside an internal cavity in the shaft.
  • the storing space is at least partially defined by an annular disc having a fastening point for the at least one supply line, said annular disc being freely rotatable with respect to the storing space and the shaft.
  • the provision of said annular disc allows the extraction and storing of the exceeding portion of the at least one supply line from/into the storing space to be de-coupled with respect to the shaft rotation.
  • the annular disc is substantially perpendicular to the aforementioned rotation axis, and the exceeding portion of the at least one supply line is housed in the storing space at least partially leaning on a face of the annular disc.
  • this makes easier the extraction and storing of the exceeding portion of the at least one supply line from/into the storing space upon rotation of the annular disc.
  • the annular disc and the shaft are rotatably connectable so that in a first part of the rotation of the shaft the annular disc is rotatably integral with the shaft and in a second part of the rotation of the shaft the annular disc is idle with respect to the shaft.
  • the shaft comprises a window that perimetrally formed at a side surface thereof to allow the entry of the at least one supply line into the internal cavity in the shaft.
  • this window whose perimeter size can be suitably dimensioned, makes at least a partial shaft rotation possible when the annular disc is idle - and, thus, the exceeding portion of the at least one supply line is not pulled from the storing space - without any interference occurring between the at least one supply line and the shaft.
  • the invention in a second aspect thereof, relates to a machine for working block or slab materials comprising a displacing apparatus for a tool holder assembly of the aforementioned type.
  • the invention in a third aspect thereof, relates to a method for working block or slab materials comprising the steps of: a) providing a block or slab to be worked on a work surface; b) displacing a working tool associated with a tool holder assembly to perform a working operation on said block or slab, wherein said step of displacing the working tool is carried out by means of a displacing apparatus comprising: a shaft supporting, at a first longitudinal end thereof, said tool holder assembly, and at least one supply line connected to said tool holder assembly and comprising a portion exceeding the length of said shaft, and wherein said step of displacing the working tool is carried out at least partially by inserting or storing said exceeding portion into/from a respective storing space associated with said shaft during the displacement of the tool holder assembly.
