Problems solved by technology

[0020] In addition, in the grinding process of the lens performed by the numerical control cutting device 600, the processing time of one lens takes about several minutes.
Therefore, the processed lens is taken out one by one from the conveying tray for processing, the processed processed lens is conveyed back to the original position of the conveying tray, and the next processed lens is carried into the grinding device one by one for processing. , there is a problem of poor efficiency

Abstract

The present invention relates to a polishing jig for mounting a working object lens on a polishing apparatus that polishes the concave surface of the working object lens, a conveyor tray for exclusive use for conveying the polishing jig, and a conveying method and a conveying apparatus for conveying the polishing jig or the like with the working object lens held thereon to a working apparatus such as the polishing apparatus. The polishing jig (1) of the present invention includes a mounting portion (2) to be mounted on a chuck of a polishing apparatus, a ring-shaped closely contacting portion (3) for closely contacting with a convex surface (11) of a working object lens (10), and a filling gap portion (4) having an opening at the closely contacting portion for being filled with adhesive substance (7) which adheres to the convex surface of the working object lens closely contacted by the closely contacting portion to hold the working object lens. The polishing jig is suitable for a numerically controlled polishing apparatus. The conveyor tray of the present invention has an accommodation section for receiving the polishing jig described above on which a working object lens is held, a through-hole for passing therethrough a jig which moves the polishing jig up and down, and a projection for engaging with a recess (54) of the polishing jig.

Description

[0001] This application is a divisional application of the earlier application (application date: July 25, 2002, application number: 02814897.5, title of invention: grinding jig, pallet for conveying, conveying method and conveying device). technical field [0002] The present invention relates to a polishing jig for attaching a lens to be processed to a polishing device for concave grinding of a lens to be processed, a pallet for transport dedicated to the polishing jig, and a polishing device for holding a lens to be processed on a processing device such as a polishing device A conveying method and a conveying device using jigs, etc. Background technique [0003] In recent years, so-called progressive multifocal lenses in which a progressive surface is provided on the concave surface side (inner surface side) of eyeglasses have been developed. Such an inner surface progressive multifocal lens can reduce waviness and distortion which are disadvantages of a progressive multi...
