Abstract

This invention relates to a bead supporter for supporting a cathode assembly of an electron gun for a cathode-ray tube and fixing the assembly to a bead glass. This invention also relates to an apparatus for sorting and transporting the bead supporters in a properly oriented posture to an assembly line. The bead supporter includes a plurality of positioning projections formed on the lower side of its central portion, and cut-out portions formed in its upper edge portion opposite to the projections to permit the center of gravity of the supporter to vary depending upon its normal and reverse positions. The apparatus includes a feeding surface and a horizontal sorting surface for transferring the bead supporters. The width of the horizontal sorting surface is less than the width of the feeding surface such that each supporter having cut-out portions formed therein falls from the sorting surface when reversely positioned. The apparatus also includes a vertical sorting wall formed perpendicularly to the feeding and horizontal sorting surfaces for guiding the supporters.

Dependent claims

An apparatus for sorting bead supporters for an electron gun of a cathode-ray tube, comprising:

a vertical sorting wall;
a horizontal feeding surface formed perpendicularly to said sorting wall for transferring said bead supporters;
and
a horizontal sorting surface having a width less than a width of the horizontal feeding surface and formed perpendicularly to said sorting wall for sorting said bead supporters, the width of said horizontal feeding surface being such that bead supporters oriented in an incorrect orientation will fall from the sorting surface;
wherein said bead supporter comprises:
a semi-circular central portion for supporting the cathode assembly;
a plurality of positioning projections formed on a lower inward side of the semi-circular central portion of the bead supporter;
and
a pair of extended portions projecting from said semi-circular central portion, parts of each of the pair of extended portions projecting to positions outward of the semi-circular central portion, for fixing a cathode assembly to opposing bead glasses;
wherein a cut-out portion is formed in an upper edge of at least one extended portion of the bead supporter, said cut-out portion causing said bead supporter to fall from said supporting surface if said bead supporter is incorrectly oriented.
