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 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.

Abstract

A method for checking the functionality of a vibratory conveyor device (1) by means of a status analysis which is carried out either before operation or during operation of the vibratory conveyor device (1), wherein A) the method to be carried out before operation comprises the following steps: A1) applying a drive pulse to a drive device (2) of the vibratory conveyor device (1); A2) detecting the pulse response caused by the vibratory conveyor device (1); A3) passing on the detected pulse response by way of the signal evaluation unit (5) to a computer (6); A4) comparing the detected pulse response to a reference pulse response by means of the computer (6); and A5) ascertaining by means of the computer (6) whether: a) a starting procedure for operation with reduced starting drive power of the vibratory conveyor device (1) is to be activated, or b) a starting procedure for operation without reduced starting drive power of the vibratory conveyor device (1) is to be activated, or c) the operation is to be suspended; B) the method to be carried out during operation comprises the following steps: B1) detecting the voltage amplitude, frequency, acceleration, and temperature, caused by the vibratory conveyor device (1), in operation of the vibratory conveyor device (1) by means of the signal evaluation unit (5); and B2) passing on the detected voltage amplitude, frequency, acceleration, and temperature by way of the signal evaluation unit (5) to a computer (6).
