Lifting conveyor belt
The invention is an elevator conveyor belt ( 1 ) suited to promote the handling of materials M, comprising: a supporting structure ( 2 ): a first transport element ( 3 ) anchored to the structure ( 2 ) and having a first flat surface ( 4 ) intended to support the material (M), said first flat surface ( 4 ) extending continuously along a longitudinal extension direction (L) between a loading area (Zc) and an unloading area (Zs): handling means ( 9 ) anchored to the supporting structure ( 2 ) to promote the controlled movement of the first transport element ( 3 ) along a direction of advance (A) substantially parallel to said longitudinal extension direction (L). During the operation of the handling means ( 9 ), the material (M) is loaded onto, and respectively unloaded from the first transport element ( 3 ) at the loading area Zc, and respectively at the unloading area (Zs). There is a second transport element ( 14 ) placed over at least one portion of the first transport element ( 3 ), said second transport element ( 14 ) being provided with a plurality of substantially transverse crosspieces ( 15 ) suited to be arranged over the first flat surface ( 4 ) of the first transport element ( 3 ) so as to interact with the material (M) and guide it during transport from the loading area (Zc) to the unloading area (Zs).
1 . An elevator conveyor belt configured to promote handling of materials consisting of heterogeneous elements, said elevator conveyor belt comprising:
a supporting structure;
a first transport element anchored to said supporting structure and having a first flat surface configured to support the material to be transported, said first flat surface extending continuously along a longitudinal extension direction between a loading area for the material to be transported and an unloading area for the transported material;
a handling system anchored to said supporting structure and configured to promote controlled movement of said first transport element along a predetermined advance direction substantially parallel to said longitudinal of said first flat surface, during the operation of said handling system, the material being loaded onto, and respectively unloaded from, said first transport element at said loading area, and respectively at said unloading area; and
a second transport element disposed over at least one portion of said first transport element, said second transport element-being provided with a plurality of crosspieces substantially positioned crosswise and configured to be disposed over said first flat surface of said first transport element to interact with the material and guide the material while the material is transported from said loading area to said unloading area, each of the crosspieces having a free edge substantially positioned crosswise, the free edge being disposed in proximity to the first flat surface of the first transport element, the free edge of the crosspiece being configured to interact with the first flat surface to exert a predetermined pressure on the first flat surface.
2 . The belt according to claim 1 , wherein the free edge of each crosspiece of said plurality of crosspieces is substantially in contact with said first surface of said first transport element to completely hold the material placed thereon.
3 . The belt according to claim 1 , wherein said first surface has a central portion configured to interact with the material to be transported, said central portion having a predetermined width.
4 . The belt according to claim 3 , wherein said crosspieces of said second transport element are configured to overlap said first flat surface at said central portion.
5 . The belt according to claim 3 , wherein each of the crosspieces of said plurality of crosspieces has a width substantially equal to the width of the central portion of said first surface.
6 . The belt according to claim 1 , wherein said first transport element has a pair of substantially parallel terminal edges extending from said first flat surface along a transverse direction substantially orthogonal to the transverse extension direction defined by said crosspieces.
7 . The belt according to claim 6 , wherein said terminal edges are configured to delimit said central portion of said first flat surface of said first transport element.
8 . The belt according to claim 7 , wherein the height of said terminal edges of said first transport element is substantially equal to the height that of one or more crosspieces of said plurality of crosspieces.
9 . The belt according to claim 1 , wherein said second transport element has a second flat surface positioned over said first flat surface of said first transport element.
10 . The belt according to claim 9 , wherein said second flat surface is substantially parallel to said first flat surface.
11 . The belt according to claim 10 , wherein each of the crosspieces of said plurality of crosspieces is joined to said second flat surface at a terminal edge to form a single assembly together with said second flat surface.
12 . The belt according to claim 9 , wherein said second flat surface has a predetermined width that is greater than the width of said central portion of said first flat surface, said second flat surface being configured to completely cover each of said terminal edges of said first transport element.
13 . The belt according to claim 1 , wherein said handling system is configured to promote a controlled movement of said second transport element.
14 . The belt according to claim 13 , wherein said handling system is configured to promote a movement of said first transport element and the movement of said second transport element substantially at the same advance speed, said first transport element and said second transport element being configured to be moved along the advance direction at a relative speed substantially equal to zero.
