Abstract
A belt conveyor system has a rotatable first roller and a second roller tapered toward a first end thereof and located substantially parallel to and at a distance from the first roller. The system also has a conveyor belt passed around and stretched between the first and second rollers for endless traveling. The system further includes a regulating member located at a position close to a first end of the first roller, opposite the first end of the second roller. The regulating member is in sliding contact with an end side of the conveyor belt only in a region where the conveyor belt is in contact with the first roller.
Claims6
A belt conveyor system comprising:
- a rotatable first roller having a first end and a second end;
- a second roller having a first end and a second end, the second roller being tapered toward the first end thereof and being located substantially parallel to and at a distance from the first roller;
- a conveyor belt passed around and stretched between the first and second rollers for endless traveling, the first ends of the first and second rollers disposed along one side of the conveyor belt and the second ends of the first and second rollers disposed along the other side of the conveyor belt;
- and
- a regulating member located at a position close to the first end of the first roller, the regulating member configured to be in sliding contact with an end side of the conveyor belt only in a region where the conveyor belt is in contact with the first roller.
A belt running method for use in a belt conveyor system, the belt conveyor system comprising a first roller having a first end and a second end, a second roller having a first end and a second end, the second roller being tapered toward the first end thereof and being located substantially parallel to and at a distance from the first roller, a conveyor belt passed around and stretched between the first and second rollers where the first ends of the first and second rollers are disposed along one side of the conveyor belt and the second ends of the first and second rollers are disposed along the other side of the conveyor belt, and a regulating member located at a position close to the first end of the first roller, said method comprising the steps of:
- rotating one of the first and second rollers to drive the conveyor belt in an endless path;
- moving the conveyor belt toward the first ends of the first and second rollers in accordance with a tapered shape of the second roller;
- and
- permitting the regulating member to be in sliding contact with one end side of the conveyor belt only in a region where the conveyor belt is in contact with the first roller.
