Title:
FLAT BELT CONVEYING DEVICE
Document Type and Number:
Japanese Patent JP2008285312
Kind Code:
A
Abstract:
To provide a flat belt conveying device capable of sufficiently exhibiting large conveying ability and maintaining stable high load transmission for a long period of time.
An endless flat belt 20 is wrapped around knife edge-like belt support parts 11, 12 and a drive pulley 30. In the drive pulley 30, a projection is formed on a cylindrical outer peripheral surface wrapped around with the flat belt 20. An angle relative to an outer peripheral surface of a traveling direction side portion of the flat belt 20 of the projection is 90 or less. By action of the projection, drive force of the flat belt 20 can be enhanced, and by suppressing tension of the flat belt 20 to a low degree, resistance in the belt support parts 11, 12 can be reduced.
