Definitions

  • the present patent application for industrial invention relates to a mechanism for the support and movement of the tool table in machines for automatically polishing edges of circular profile of slices of marble, granite and the like.
  • machines capable of automatically performing the above-mentioned operation for shining rounded ribs; they essentially comprise a table, with a horizontal axis, for supporting a series of aligned tools, each equipped with its own motor, a conveyor belt on which the slice of marble to be polished is loaded and a support and movement mechanism for the tool table, which must be able to move from all sides while maintaining its own longitudinal axis always parallel to itself, so that all the tools can intervene along all the points of the profile rounded off the edge of the edge to be polished.
  • a mechanism corresponding to the preamble of claim 1 is known, for example, from EP-A-0 197 233.
  • the present invention aims to create a support and movement mechanism for the above-mentioned tool table different from those used until now, in relation to which it can boast a greater simplicity of construction and, consequently, an easier and economical realization as well as a greater reliability of operation.
  • the mechanism according to the idea includes the use of two identical parallelograms, simple and opposite articulated, each formed by two identical pendulums and a connecting rod, provided that the pendulums are actuated by a motor device capable of making them oscillate around their own pivot axes to the chassis.
  • a support hole is provided for the two studs, coaxial and opposite, which are at the two ends of the tool table.
  • the mechanism according to the idea makes it possible to move the tool table in all directions while keeping the inclination of its longitudinal axis constant which assumes directions that are always parallel in all the positions where the table stops and this thanks to the use of the two simple articulated parallelograms mentioned above.
  • the tools installed on the table therefore, can assume all directions and distances from the edge of the slice of marble to be polished thanks to a suitable combination and juxtaposition of movements that can be given to it, one by means of two simple articulated parallelograms, the other by means of the table support studs, suitably motorized.
  • the mechanical device which the idea comprises two identical simple articulated parallelograms (1), each of which is formed by two identical pendulums (1a) and a connecting rod (1b), being provided only on the pendulums (1a) are securely anchored the studs (1c) in correspondence of which the said pendulums are pivoted on the chassis of the polishing machine.
  • a gear (2) is fitted and which, put in alternating rotations, by a drive chain not illustrated in FIGS. 5 and 6, causes the pendulums (1a) to perform continuous and alternating oscillations, with the same angle of rotation.
  • Each connecting rod (1b) of the simple articulated parallelograms (1) has, in the center, a hole capable of accommodating exactly a stud (3) solidly fixed at the two ends of the table (4) which supports the tools (5), these being made in this case of cup-shaped grinding stones.
  • a gear (3a) is fitted which, rotated by a drive chain (6) (see fig. 5) or by a driving gear (7) (see fig. 6) causes the table (4) to perform an equal and simultaneous rotation around its own pivot pins (3).
  • the mechanism according to the idea also offers another important advantage compared to equivalent mechanisms already known and which is mainly due to its structural conformation which allows, differently from the previous kinematic solutions, to include and isolate the two support and movement mechanisms of the tool table in two separate housings, inaccessible to water and waste machining which is normally deposited on the tool table.
  • the two support and movement mechanisms of the tool table (4) can be hidden and protected in two lateral housings (8), without thereby creating construction difficulties, since it suffices to provide only, on the two internal lateral walls (8a) of these housings, two curved buttonholes (8b) through which pass and in which the pivot pins (3) of the table (4) move.
