GRAVITY TYPE WHEEL CONVEYOR OR ROLLER CONVEYOR CAPABLE OF CONTROLLABLY BRAKING CARRIED OBJECT.

摘要

A gravity type wheel conveyor or roller conveyor capable of relieving or loweringthe carrying speed of a rather lightweight carried object by braking wheels orbraking rollers or capable of controllably braking it to stop to a target position.A plurality of freely rotating wheels (4) or rollers (10) are arranged parallelwith each other in an article carrying direction and the carried object (1) iscarried by the action of its gravity. The selected one or more of the wheels (4)or rollers (10) are configured as the braking wheels (6) or the braking rollers(12) formed by mounting a soft and highly resilient braking material (7) or (11)on their outer peripheral surfaces so as to be radially projected from the outerperipheral surface of the wheels or the rollers.
