Title:
SMALL DIAMETER MAGNET-DRIVEN ROLLER CONVEYOR
Document Type and Number:
Japanese Patent JP2007331943
Kind Code:
A
Abstract:

To perform accumulation by arranging a driven magnet on a carrier roller side with a small roller pitch perpendicular to a line shaft provided with a drive magnet to make a drive roller conveyor suitable for conveying a short small size work.

The drive magnet 12 is made into a bead shape, the respective two driven magnets 14 are closely arranged respectively and the carrier roller 10 is driven. Thereby, the driven magnets and the drive magnet are arranged on a two-to-one basis to make a clearance of the drive magnet 12 arranged on the line shaft twice the carrier roller pitch, and a bearing is assembled in between an arbitrary carrier roller pitch. The driven magnet 14 having a smaller diameter than the carrier roller 10 is fitted to a carrier roller shaft 11 at a position one-sided to one of a conveyor frame, interference of the drive magnet and the carrier roller is prevented and a pass line is ensured to convey an extremely small work.
