Abstract

A support station (9) for a movable belt conveyor includes:

• • a support cradle (17) for the belt (3), the cradle (17) including at least one roller (31, 33) for guiding and supporting the belt (3);
  • a frame (15) for supporting the or each roller (31,33);
    • at least one anti-jamming protection element (35, 37) fixed to the frame (15), the protection element (35, 37) being disposed along at least one of the rollers (31, 33) and having an elongate shape longitudinally substantially parallel to a generatrix of the roller (31, 33), characterized in that the protection element (37) includes at least first and second longitudinal profile sections (41, 43) having respectively first and second cross-sections that are different from each other.

Claims

1. Support station for a movable belt conveyor, the support station (9) comprising:

a support cradle (17) for the belt (3), the cradle (17) comprising at least one roller (31, 33) for guiding and supporting the belt (3);

a frame (15) for supporting the or each roller (31, 33);

at least one anti-jamming protection means (35, 37) fixed to the frame (15), the protection means (35, 37) being disposed along at least one of the rollers (31, 33) and having an elongate shape longitudinally substantially parallel to a generatrix of the roller (31, 33), characterized in that the protection means (37) comprises at least first and second longitudinal profile sections (41, 43) having respectively first and second cross-sections different from each other, and in that the protection means (37) comprises a longitudinal metal core (39), the profile sections (41, 43) being clipped onto the metal core (39).

2. A support station according to claim 1, characterized in that the first and second profile sections (41, 43) are made of a plastics material.

3. A support station according to claim 1, characterized in that the first and second profile sections (41, 43) are disposed respectively towards the outside and towards the centre of the support station (9) and have faces (55, 45) turned towards the belt (3) that are respectively relatively wider and relatively less wide.

4. A support station according to claim 3, characterized in that the faces (55, 45), turned towards the belt (3), of the first and second profile sections (41, 43) are separated from the roller (33) by gaps that are respectively relatively narrower and relatively wider.

5. A support station according to claim 1, characterized in that each profile section (41, 43) has a face (59, 49) turned towards the roller (33) and a seat (63) for receiving the metal core (39) open on the face (59, 49) turned towards the roller (33).

6. A support station according to claim 1, characterized in that the frame (15) comprises two support notches (67) for the protection means (37) that are disposed longitudinally on either side of the protection means (37), the notches (67) being each delimited by an open peripheral edge, the opposed end portions (69) of the core (39) being engaged in the notches (67).

7. A support station according to claim 6, characterized in that at least one of the end portions (69) of the core (39) protrudes out of the notch (67) and is bent with respect to the longitudinal direction.

8. A support station according to claim 1, characterized in that the metal core (39) is a solid iron bar of flat cross-section.

9. A support station according to claim 1, characterized in that the cradle (17) comprises at least one central roller (31) and two end rollers (33) disposed on either side of the central roller (31), the rollers (31, 33) being disposed in prolongation of each other, and the station comprising for each of the two end rollers (33) a protection means (37) equipped with two longitudinal profile sections (41, 43) having cross-sections that are different from each other, and for each central roller (31) a protection means (35) equipped with a single profile section (43).

10. A support station according to claim 2, characterized in that the first and second profile sections (41, 43) are disposed respectively towards the outside and towards the centre of the support station (9) and have faces (55, 45) turned towards the belt (3) that are respectively relatively wider and relatively less wide.
