Device for the transport of ceramic slabs

A device for the transport of ceramic slabs (L), comprising:

• a pair of inner belts (2,3), parallel to a transport direction (x) and coplanar to a transport plane, each of which is associated to a respective support unit (210,220,310,320);
• a pair of outer belts (4,5), parallel to a transport direction (x) and coplanar to the transport plane, each of which is associated to a respective support unit (410,420,510,520);
• wherein the pair of inner belts (2,3) is interposed between the two outer belts (4,5);
• characterised in that:
• front supports (210,310,410,510) of the belts (2,3,4,5) are slidably associated to a front bar (6), arranged perpendicular to a transport direction (X) and parallel to the transport plane;
• the front bar (6) comprises a first threaded portion (61) and a second threaded portion (62), in which the threads of the first portion (61) and of the second portion (62) are screwable in opposite directions, wherein the first threaded portion (61) and the second threaded portion (62) respectively comprise a first section (611,621) and a second section (612,622) with threads having a different pitch;
• the front supports (210,410) of an inner belt (2) and of an outer belt (4) are associated, by a threaded coupling, to the first portion (61) of the front bar (6);
• the front supports (310,510) of the other inner belt (3) and of the other outer belt (5) are associated, by a threaded coupling, to the second portion (62) of the front bar (6);
• and
• motor means is predisposed to activate the front bar (6) in rotation, so as to displace the front supports (210,310,410,510) along the front bar (6), in a perpendicular direction with respect to the transport direction (X) and parallel to the transport plane.
