Document Type and Number:
Japanese Patent JP2009062188
Kind Code:
A
Abstract:

To provide a sorting device for reducing cost, reducing a maintenance burden, and reducing a work burden, by reducing the number of part items by simplifying a mechanism, and suitable even for use in a clean environment by restraining scattering of abrasion powder.

This sorting device is provided for carrying a carrying object in the predetermined direction by rotating and rocking cylindrical rollers 160 arranged in a plurality in the carrying direction and the width direction of an article carrying passage in the two-dimensional direction composed of the carrying direction and the width direction. The cylindrical rollers 160 have an iron cylindrical body 160a and a cylindrical layer 160b composed of nonmagnetic metal formed on its outside. The problem is solved by providing a primary winding 100 of a linear guide motor type X-Y actuator for generating an advance magnetic field for rotating and rocking the cylindrical rollers 160 in the two-dimensional direction on the side under the article carrying passage.
