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.
Conveyor, particularly a hinged belt conveyor, preferably for metal waste such as chips or the like, with a conveyor frame, U-shaped in cross section, having side pieces having upper and lower inwardly bent legs, said side pieces being connected by cross pieces one end of which is provided with a drive station which is adjustable in the longitudinal direction of the conveyor and is supported by means of an abutment, and the other end of which is provided with a reversing station for said endless flexible hinged belt which includes running rollers said other end including guide channel means supporting said rollers constituted by U-shaped formed metal sheet means having upper and lower inwardly bent legs, and a webb, fastened to the inside of said side pieces connected by said cross pieces a chute plate and arcuate guide means located in the reversing regions for the conveyor belt, characterized in that the arcuate guide means comprising releasably fastened solid curved pieces, one pair of which is fastened, at the reversing station, to the underside of said chute plate which extends downwards, between the side pieces from the top side of the reversing station towards the hinged belt, the lower legs of said side pieces which guide the return side of the hinged belt are connected by means of a U-shaped base plate means which is at least partially disposed around the reversing station with the exception of the top side of the latter.
