ABSTRACT:
A part of the arcuate guides for the hinged belt (13) of the conveyor consists of solid curved pieces (247, 270) which are fastened releasably to parts of the conveyor frame. In the region of the drive station, guide plates (35; 299) which are fastened to the side pieces (17, 18; 220) are assigned to the empty side of the hinged belt. A U-shaped baseplate (20; 232) is connected with its upwardly projecting legs, to the side pieces (17, 18; 220). If the conveyor is a lifting conveyor with a lower and an upper horizontal longitudinal section as well as with a longitudinal section which is directed obliquely upwards, the arcuate guides consist of curved crosspieces (33, 34; 276, 294) which extend between the side pieces (17, 18; 220), in the region of the mutually angled longitudinal sections. The lower and middle longitudinal sections of the conveyor can each be connected partly by means of a welded-in gusset plate, the inner sides, lying opposite one another, of the gusset plates (265) and of adjacent side pieces (220) being welded to the curved crosspiece (276). The baseplate (20; 232) leaves an intervention opening (47) free in the region of the drive station (M). Reversing drums (37; 240) for the hinged belt (13) are located at the reversing station (U). A spring element (66) which smooths out changing tensile stresses is adjustable together with the drive unit when the hinged belt (13) is tensioned. The abovementioned features permit a compact construction, resistant to warping and to bending, of the conveyor, together with a long life. The invention also relates to a process for manufacturing the conveyor.
