ABSTRACT

The present invention relates to a spiral-tightening device for a modular
spiral tower ( 1 ) of a vertical vibrating conveyor (S), in which vibrating
conveyor a wedge slider ( 4 ) is inserted between the drive ( 3 ) and the
spiral tower ( 1 ). The wedge slider comprises an anchor plate assembly ( 25
), which is vibratable, i.e. is coupled to a drive, and a wedge assembly ( 24
), which is at rest, i.e. is decoupled from the drive. A wedge ( 12 ) in said
wedge slider ( 4 ) can be slid by means of an electronically controlled
stepper motor ( 18 ) and, in the process, loads or relaxes a spring element (
13 ), which transfers its predetermined spring force to a tension anchor ( 7
). Said device allows stable vibratory behavior to be ensured and comprises a
controller for closed-loop control of the operation of said wedge slider ( 4
), i.e. allows the installation and assembly, operation, and removal and
disassembly of the spiral tower ( 1 ) to be semiautomatically controlled.
Principally, said spiral-tightening device and the method for closed-loop
control of the operation thereof are suitable for use in the case of vibrating
conveyors having a conveying height of over approximately 2.5 m, in particular
from approximately 2.5 m to approximately 5 m.
