Abstract

DC60 (25/07/40) The belt steering assembly for centering the conveyor belt (5) consists of a mechanism with a steering roller (1) and a guide roller (9). In the event of belt misalignment (5), the belt motion is transferred from the guide roller (9) to the steering roller (1), causing the steering roller to return to the neutral position. A better ratio is described between the different lengths of the lever arms (6) for such motion transfer. The procedure for loading the weight onto the conveyor belt consists of moving the conveyor belt (5) transversely before loading to a position where the center of gravity of the loaded material (15) falls on the center section (12) of the conveyor belt, and steering the conveyor belt transversely after loading to the neutral position. The belt steering assembly for centering the conveyor belt (5) consists of a mechanism with a steering roller (1) and a guide roller (9). In the event of belt misalignment (5), the belt motion is transferred from the guide roller (9) to the steering roller (1), causing the steering roller to return to the neutral position. The load is transferred from the guide roller (9) to the steering roller (1), causing the steering roller to return to its neutral position. A better ratio is described between the different lengths of the rocker arms (6) for transferring such motion. The procedure for loading the load onto the conveyor belt consists of moving the conveyor belt (5) transversely before loading to a position where the center of gravity of the loaded material (15) falls on the center section (12) of the conveyor belt, and steering the conveyor belt transversely after loading to its neutral position.

Claims (8)

1. The belt steering assembly for the centering of the conveyor belt (5) is located where the steering plate (2) supports at least one steering roller (1) for steering the conveyor belt (5). The steering plate (2) is fixed in a rotatable manner at the first pivot point (4), whose axis extends perpendicular to the conveyor belt, and the steering plate is connected to the lever arm (6) at a distance (a) from the first pivot point (4) in the conveyor direction (P1) through the first pivot joint (17). The lever arm (6) extends mostly in the longitudinal direction of the conveyor belt and is attached to the second pivot point (18), whose axis extends perpendicular to the conveyor belt at a distance (b) from the first pivot joint (17) in the conveyor direction (P1), and the arm is attached to the guide plate (7) at a distance (c) from the second pivot point (18) in the conveyor direction. Through the second pivot joint (8), a guide plate (7) supports the guide rollers (9) positioned adjacent to each outer side of the belt (5) in response to transverse displacement in the (P2) direction of the conveyor belt. This guide plate (7) is connected to the support shaft (13) through the third pivot joint (14). The support shaft (13), which extends parallel to the rocker arm (6), extends to the third stationary pivot point (20), whose axis extends perpendicular to the conveyor belt. Specifically, the ratio between the distance b between the first pivot joint (17) and the second stationary pivot point (18), and the distance c between the second stationary pivot point (18) and the second pivot joint (8) is between 1:2 and 1:5, ideally between 1:2.5 and 1:3.5, and the best is approximately 1:3. The first, second and third stationary pivot points are thus able to be adjusted transversely relative to the longitudinal direction of the conveyor belt. For example, By attaching it to a movable rectangular tube in a slip-on configuration, it allows for transverse adjustment of the neutral position of the conveyor belt. 2. A belt steering assembly conforming to the first claim shall have the following characteristics: the steering roller (1) shall be attached around an axis which is in most cases protruding and intersecting the longitudinal direction of the belt (5), and such axis passing through the first stationary pivot point (4) shall intersect, or in most cases intersect, the protrusion of the axis of rotation of the steering roller (1). 3. A belt steering assembly conforming to any one of the preceding claims shall have the following specific characteristics: the distance (a) between the first stationary pivot point (4) and the first pivot joint (17) shall be equal to, or in most cases be equal to, the distance (b) between the first pivot joint (17) and the second stationary pivot point (18). 4. The belt steering assembly conforming to any one of the preceding claims shall have the following specific characteristics: the length of the parallel support (13) shall be equal to or, in most cases, equal to the distance (c) between the first pivot point and the second pivot point (18), and the second pivot joint (8) and the third stationary pivot point (20) shall be positioned in the same transverse plane or, in most cases, in the same transverse plane as the second stationary pivot point (18). 5. The belt steering assembly conforming to any one of the preceding claims shall have the following specific characteristics: the guide roller (9) shall be positioned so that it can be received transversely, for example, by means of a tube fitting, and the guide roller (9) shall be positioned adjacent to each outer side of the belt (5) with a gap which, when such belt is in the neutral position, shall be between 1 and 10 mm. Ideally, it shall be between 3 and 8 mm. and ideally, it shall be between 5 and 6 mm. 6. Method for loading conveyor belts. A transversely adjustable conveyor belt (5) is moved through the loading device (16) for better loading of granular material (15), and the center of gravity of the loaded material (15) is located on the side of the center section of the conveyor belt (12) when the conveyor belt is in the neutral position. Specifically, before loading, the conveyor belt (5) is turned transversely to a position where the center of gravity of the loaded material (15) is located on the side of the center section of the conveyor belt (12), and after loading, the conveyor belt is moved to the neutral position. 7. The procedure which conforms to claim 6, with a specific characteristic being that the steering which is in the transverse direction of the conveyor belt (5) will be performed by the conveyor belt steering mechanism. 8. The procedure which conforms to claim 6 is that the conveyor belt (5) is positioned in the stand (21) with the conveying side for the material at the top of the stand and the reverse movement side for the belt at the underside of the stand, and the loading is performed on the conveying side at the end of the stand, with the belt moving from the underside to the top of the stand. Specifically, prior to loading, the transverse steering of the conveyor belt (5) is performed by the steering mechanism on the underside of the stand, and after loading, the transverse steering of the conveyor belt is performed by the belt steering mechanism at the top of the stand.
