Device for removable fastening of seats for housing containers to a metallic belt conveyor

A device (D) for removable fastening of seats (3) for receiving containers (C) on a metallic belt (1), said metallic belt (1) receiving the containers (C) and moving the containers in said seats (3), along an active sliding surface (100) in a predetermined forward direction (W), said device comprising:

• first fastening means (10) made on said metallic belt (1) for mutually connecting to second fastening means (34), made in a lower part of said seats (3), for positioning and locking said seats (3) to said bell (1);
• said first fastening means (10) and said second fastening means (34) allowing the seats (3) to move crosswise wit respect to said direction (W) between a first unlocking position, in which said first fastening means (10) and said second fastening means (34) are unlocked, and a second working position, in which said first (10) and second (34) fastening means are mutually looked;
• supporting and sliding guides (4,5) located opposite to each other and situated below said active sliding surface (100), substantially orthogonal to said metallic belt (1), and having opposed wails there between defining a free space area (Y), into which said second fastening means (34) extend, the supporting and sliding guides forming surfaces (42,52) on which the metallic belt (1) is supported and slides;
• guide operating means for moving the supporting and sliding guides between a first gripping configuration (P), in which the guides are vertical and form an abutment for said second fastening means (34), to provide a secure fastening, said metallic belt being supported in a direction (z) crosswise to said direction (W), when said seats (3) for housing containers (C) are arranged in said second working configuration (21), in which said first (10) and second (34) fastening means are mutually locked, and a second release configuration (R), in which at least one of said guides (4,5) is moved away from said second fastening means (34), so as to allow said seats (3) to slide in a direction (Z2), crosswise to the forward direction (W), toward said first unlocked position (20), for removing said seats (3) from said metallic belt (1).
