Patent number: 6776280Abstract: The present invention relates to a belt guidance unit for centring a conveyor belt, which during operation is susceptible to lateral displacement away from a neutral position in its longitudinal direction. According to the invention the belt guidance unit can be employed on conveyor belts that move in one direction as well as in two opposite directions with only very slight alterations and the basic constructional features of the belt guidance unit are substantially identical in the two operational situations.Type: GrantFiled: September 29, 2003Date of Patent: August 17, 2004Assignee: Martin Engineering CompanyInventors: Kenneth Hovstø, Kjell Arne Gaarden

Patent number: 6247580Abstract: The actuator device for use in a bi-directional conveyor belt comprises a toothed wheel which rotates depending on the belt's transport direction and is engaged with a toothed rack on a toothed element which is movable between two extreme points and which has at each end portion a pin which, when a force is applied in the direction of the end of the toothed element, is arranged to move to a position in which it forms a tooth as an extension of the toothed rack, and when a force is applied in the direction of the opposite end of the toothed element is arranged to move to a retracted, yielding position relative to the toothed rack.Type: GrantFiled: November 5, 1999Date of Patent: June 19, 2001Assignee: A/S Techno TrackInventors: Kenneth Hovstø, Kjell Arne Gaarden

Patent number: 6186317Abstract: A reversible belt steering assembly for centering of conveyor belts which during operation is subjected to a lateral displacement away from a neutral position. A rotating mechanism (3, 19) supports at least one steering roller for the conveyor belt, and is rotatably attached to a first fixed beam (2) for rotation about an axis (a) perpendicular to the conveyor belt. A first set of guide rollers (9) abuts the sides of the conveyor belt, and is thus displaced laterally depending on the lateral displacement of the conveyor belt, and a first transfer mechanism supports the first set of guide rollers (9) for transferring the lateral displacement of the first set of guide rollers (9) to the rotating mechanism (3, 19), to rotate the steering roller to a position where it guides the conveyor belt back to the neutral position. There is a second set of guide rollers (9′) corresponding to the first set of guide rollers, and a second transfer mechanism corresponding to the first transfer mechanism.Type: GrantFiled: December 28, 1998Date of Patent: February 13, 2001Assignee: A/S Techno TrackInventors: Kenneth Hovsto, Kjell Arne Gaarden

Patent number: 6131726Abstract: A belt steering assembly for centering of conveyor belts (5) comprises a mechanism with steering rollers (1) and guide rollers (9). In the event of a lateral misalignment of the belt (5), the belt's movement will be transferred from the guide rollers (9) to the steering rollers (1), with the result that the steering rollers return the belt to a neutral position. Preferred ratios are described between different lengths of a lever arm (6) for transfer of the movement. A method for loading of a conveyor belt comprises moving the conveyor belt (5) laterally before loading to a position where the centre of gravity of the loaded material (15) falls on the conveyor belt's central portion (12), and after loading steering the conveyor belt laterally to its neutral position.Type: GrantFiled: December 28, 1998Date of Patent: October 17, 2000Assignee: A/S Techno TrackInventors: Kenneth Hovsto, Kjell Arne Gaarden
