Belt conveyor (1) having a centring assembly (2), comprising a supporting bracket (3) and two roller holders (4 A-B) each having at least a conical roller (40 A-B) that is rotatably suspended in the respective roller holder, wherein the centring assembly (2) has a supporting bracket direction (U) that rotates along with the centring assembly (2) which direction (U) in an inactive position is the same as the transport direction (T). Each of the roller holders (4A-B) comprises at least one curved arm (46A-B) and the supporting bracket (3) comprises at least two curved slides (35A-D) that are placed in the supporting bracket (3) so as to be mirror- symmetrical with respect to a plane of symmetry of the centring assembly (2), wherein the curved arms (46A-B) are placed in the curved slides (35A-D) wherein the roller holders are connected to the supporting bracket (3) so as to be adjustable at an angle.
摘要:
Die Erfindung betrifft eine Bandfördereinrichtung (1) für einen Straßenfertiger oder einen Beschicker. Die Bandfördereinrichtung (1) umfasst ein Förderband (2), an dem ein verschiebbar gelagertes Tragelement (3) anliegt und eine erste und eine zweite Kolbenzylindereinheit (5, 6) zum Verlagern des Tragelements (3). Insbesondere können die erste und die zweite hydraulische Kolbenzylindereinheit (5, 6) unabhängig voneinander mit Druck beaufschlagt werden, um das Tragelement (3) in eine gewünschte Schrägstellung zu bewegen. Wenn das Förderband (2) der Bandfördereinrichtung (1) seitlich vom Tragelement (3) abläuft, kann mit einer Schrägstellung des Tragelements (3) dem Ablaufen des Förderbandes (2) entgegengewirkt werden. Dadurch bewegt sich das Förderband (2) in eine ursprüngliche Lage zurück.

Conveyor belt device comprising a relatively long and narrow belt. In order to ensure the correct positioning of the belt over great distances, steering rollers are provided which are arranged transversely opposite one another in the direction of transport of the belt. The steering rollers are embodied such that the upper side thereof is level with the upper side of the parts of the conveying belt run which are situated further upstream and further downstream, respectively. Viewed in the transverse direction, the steering rollers close the belt in on both sides between grooves provided for that purpose. The bottoms of the grooves are at a distance which is greater than the width of the belt in said location and the surface of the steering rollers which engages with the belt run is of conical design. This ensures that the position of the belt run is automatically corrected.

There is provided a belt conveyor including a pair of right and left detection rollers (8,9) which are disposed outside both ends in a width direction of the belt, and a pair of correction rollers (10,11) which are disposed on right and left sides on a rear face of the belt. When one of the right and left detection rollers is pressed by the belt, the corresponding correction roller is inclined from the pressed detection roller down to a center of the belt, thereby easily realizing correction of the meandering belt.

In an aspect of the present invention, a system and method are provided that detect belt mis-tracking and in response, automatically adjusts. In some implementations, the system and method are implemented in conjunction with a weigh feeder or weigh belt. In other implementations, the system and method are implemented in conjunction with other devices that convey material via one or more belts. The system and method can be implemented by providing one or more sensors that detect belt mis-tracking, a motor for adjusting a belt pulley and one or more controllers that operate the motor in response to signals from the one or more sensors.

The invention relates to a conveying device substantially comprising an endless conveying element (11) which is guided across several deflecting elements (12) and is provided with a conveying sector (16) and a redirecting sector (17). The conveying sector (16) defines a conveying plane E. The conveying device further comprises a drive unit (13) for the conveying element (11) as well as elements (14) for centering the conveying element (11). The inventive conveying device is characterized in that at least the deflecting elements (12a, 12b) located at opposite ends of the conveying sector (16) are embodied as elements (14) which have an inward-oriented shape and are used for centering the conveying element (11) perpendicular to the direction of travel T.

A training idler roller assembly is provided in which the idler roller (6) is adapted to slew in a plane generally parallel to that of the conveyor belt (3) to move one or other ends of the roller (6) in the general direction of travel of the conveyor belt so as to guide the belt to return to the central desired position in the event that it drifts laterally. An idler roller unit (6) is composed of one or more idler rollers (1, 26) mounted for free rotation on one or more axles (4) with the idler roller unit having a suspension formation (13) associated with each end thereof whereby the end of the idler roller unit may be supported relative to a conveyor structure (17, 19).

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.
