A vacuum wheel for transporting a substrate includes a fixed conduit that is connectable to a suction source. A vacuum surface on a circumference of the vacuum wheel includes vacuum openings that are distributed around the circumference, such that rotation of the wheel causes the vacuum openings to successively fluidically connect to the fixed conduit. When suction is applied to the fixed conduit, suction is applied to one or more of the vacuum openings that are currently fluidically connected to the fixed conduit. At least one contact surface on the circumference of the vacuum wheel is adjacent to, and extends outward beyond, the vacuum surface. When suction is applied to the vacuum openings, the substrate is drawn toward the vacuum surface so as to contact the contact surface without contacting the vacuum surface, creating a friction force that enables transport of the substrate when the wheel rotates.

Gas bearing, porous media vacuum roller and porous media air turn

Номер: US20160068360A1
Автор: Andrew J. Devitt, Richard Duane Pollick
Принадлежит: New Way Machine Components Inc

In order to provide web handling which mitigates marking of the web, externally-pressurized porous media gas bearings are used for vacuum rollers, which provide differential tension, and also for air turns, which provide non-contact turning of webs. The porous media gas bearings mitigate three of the biggest issues with the current technology, including cost, high flow rates and low pressure, and web marking. By introducing positive pressure or both, various configurations are presented which allow for improved differential tension, or non-contact conveyance. By also employing externally-pressurized radial bearings, more alternatives are provided, including conveyance and lateral motion of webs without the use of motors. Lastly, employing novel lightweight materials allows for yet other configurations which also employ some of the same aforementioned benefits.

A roller for a transport belt of a vacuum transport assembly includes an elongate cylindrical body adapted for a rotatably fixed connection to a vacuum transport assembly. An outer surface of the roller defines a hollow inner channel, which extends along an axial region of the body. The outer surface is a running surface for a transport belt. An inlet at one end of the hollow inner channel receives air from an air source.
