Patent DE-3837115-A1 (DE)
Title: Belt-pocket conveyor
Inventor: BODE HORST
IPC: B65G17/12
Filed: 1988-11-02
Abstract: In belt-pocket conveyors vibrations of the conveying strand set in at high conveying speeds, which vibrations are connected with dynamic processes as the conveying strand runs onto the deflection discs. The uneven running of the conveying strand does not permit operation above a certain limiting speed. In the belt-pocket conveyor according to the invention, vibrations of the conveying strand at high conveying speeds are not to occur or are to be considerably reduced. For this purpose, conveying pockets 11 built up from an endless belt 12 arranged in folds, and stiff lateral walls 13 are positioned between the parallel running drawing means 8 in such a manner that the conveying pockets 11 extend on both sides of the plane 16 of the drawing elements 8, so that the centre of gravity 15 of the filled conveying pocket is situated on the plane 16. Due to variations in the mass distribution in the conveying strand, the belt-pocket conveyor makes possible vertical conveying of severely abrasive bulk materials at a high conveying speed without impairment by conveying-strand vibrations. <IMAGE>
