Suction roller and transporting apparatus using the same










Image Number 12 for United States Patent #7654427.

The present invention provides a suction roller which is capable of being adopted for sucking an object. The suction roller is provided with a negative pressure inside thereof and at least one opening for sucking the object by at least one valve disposed in each opening respectively for selectively controlling the on-off of the negative pressure through the opening. During the rotation of the suction roller, the valves in a specific area are capable of being opened so that the negative pressure can pass through the openings with respect to the opened valve to suck the object and transport the object subsequently. In another embodiment, the present invention also provides a transporting apparatus combining the suction roller and a guiding mechanism for transporting the object and compensating the shifting during the moving of the object.
