1. A module for a modular conveyor belt, said module comprising:
a base element (1) which comprises:
a first upper surface (1A),
a lower flat sliding surface (1B) for cooperation with a flat conveyor path (2),
a front edge (1C) and a rear edge (1D) parallel to each other and lateral edges (1E, 1F) parallel to each other,
and, seen in a transport direction (D), a plurality of front (3A-F) and rear (4A-E) coupling elements for coupling the modules together, separated from each other by front (5A-D) and rear (5F-I) spaces;
wherein said lower flat sliding surface (1B) extends from one to the other of said lateral edges (1E, 1F),
wherein said front and rear coupling elements (3A-F; 4A-E) are distributed along the entire width (L1) of said front (1C) and rear (1D) edges,
wherein said front and rear coupling elements (3A-F) and (4A-4E) comprise:
an upper portion (6A-J), (7A-E)
and an additional lower flat sliding surface (8) for cooperation with said flat transport path (2), and through holes (16),
wherein said additional lower flat sliding surface (8) of said front and rear coupling elements (3A-F; 4A-4E) joins and is coplanar with the lower flat sliding surface (1B) of the base element (1) to form a single flat sliding surface which extends from one to the other of said lateral edges (1E, 1F), for cooperation with said flat transport path (2),
wherein said coupling elements (3A-F) and (4A-4E) are adapted to fit the front coupling elements (3A-F) of a module (M1) into the rear spaces (5F-I) provided between the rear coupling elements (4A-4E) of an immediately adjacent module (M2), and a connecting pin (10) extending transversely to the transport direction (D) is inserted in said through holes (16) of the coupling elements (3A-F) and (4A-4E) of the two modules, hinging them together, and allowing the adjacent modules to at least partially rotate;
wherein the through holes (16) have a center (C1), (C2) provided at a first vertical distance (E1) from the lower sliding surface (8) of the coupling elements (3A-F) and (4A-4E);
wherein an outermost convex surfaces of the rear (3A-F) and front (4A-4E) coupling elements have a circular arc shape, with the centers (F1), (F2) of these circular arcs which are at a same vertical distance (E5) from the lower surface (8) of said rear (3A-F) and front (4A-4E) projecting elements and at a same horizontal distance (E7) from the outermost portion (S3) of said rear (3A-F) and front (4A-4E) projecting elements;
and a plurality of raised elements (11A-J), at least one part of which departing from the first upper surface (1A) of the base element (1) or from the upper portions (6A-J), (7A-E) of the coupling elements (3A-F) and (4A-4E), and a plurality of recesses (12A-I) (FIG. 1) which separate said raised elements (11A-J);
wherein said raised elements (11A-J) each have an upper bearing surface (13A-J), which forms a surface for transporting the products;
wherein said upper bearing surfaces (13A-J) of the raised elements are provided, at least at the coupling elements, at a second maximum vertical distance (E2) from said second lower sliding surface (8) of the coupling elements (3A-F) and (4A-4E);
wherein said upper bearing surfaces (13A-J) of the raised elements (11A-J) are provided, at least at the coupling elements (3A-F) and (4A-4E), at a third maximum vertical distance (E3) from said upper portion (6A-J) and (7A-E) of the coupling elements;
wherein the difference between the vertical distance (E5) of the centers (F1) and (F2) of the circular arc-shaped outermost convex surfaces of the rear and front projecting elements (3A-F) (4A-4E), and the vertical distance (E1) of the centers of the holes (16) for the pins (10) of the rear and front projecting elements (3A-F), (4A-4E), is greater than or equal to 1 mm.
