Abstract
A station for supporting a moving conveyor belt (3) includes a cradle (17) for guiding the belt (3), the cradle (17) having at least two rollers (33) for guiding and supporting the belt (3), a frame (15) for supporting the rollers (33), and anti-jamming protection (35) disposed along the rollers (33) and secured to the frame (15). Protection (35) includes a protective bar (36) extending continuously along the length of at least two rollers (33), being substantially parallel to a generator line of each roller (33).
Claims15
A conveyor (1), comprising:
- a set of support stations (9);
- and
- a transport belt (3) suitable for traveling over the stations (9), each station comprising:
- a cradle (17) for guiding the belt (3), the cradle (17) comprising at least two rollers (31, 33) for guiding and supporting the belt (3);
- a frame (15) for supporting the rollers (31, 33);
- and
- anti-jamming protection (35) disposed along the rollers (31, 33) and secured to the frame (15);
- wherein the protection (35) comprises a protective bar (36) extending continuously along a length of at least two rollers (31, 33) extending substantially parallel to a generator line of each roller (31, 33), wherein the bar (36) is bent and matches a curvature of the guide cradle (17), the bar (36) comprising an elongate core (38) and a sheath (39) surrounding the elongate core (38), the belt and the bar (36) at each station being spaced apart by non-zero spacing (e), and the rollers (31, 33) and the bar (36) are spaced apart by a spacing (e′) which is non-zero and is less than 10 millimeters.
