Work carrier assembly

Claim 2

A work carrier assembly, comprising: first and second work carrier members separably engaged with each other and each provided with a plural number of parallel work holder rods for supporting flat plate-like work pieces; work holder rods of said two carrier members being located in vertically staggered positions and shifted relative to each other in a forward or rearward direction in terms of travel direction of said carriers and also in a the vertical direction in such a way that said work pieces are supported on said work holder rods of one of said carrier members when said two carrier members are engaged with each other and picked on said work holder rods of the other carrier member when said two carriers are disengaged from each other.

Claim 3

A work carrier assembly, comprising: a first carrier member mounted on a work treating apparatus for supporting a plural number of disc-like work pieces while undergoing a treatment on said apparatus; a second carrier member vertically movable into and out of engagement with said first carrier member for loading and unloading a plural number of work pieces to and from said first carrier member; each one of said first and second carrier members being provided with a plural number of parallel work holder rods each having a plural number of circumferential grooves at intervals along the length thereof for engagement with peripheral edge portions of said work pieces for holding same in predetermined spaced upright positions; work holder rods of said two carrier members being located in vertically staggered positions and shifted relative to each other in a forward or rearward direction in terms of travel direction of said carriers and also in a the vertical direction in such a way that said work holder rods of said second carrier member take lower work support positions than said work holder rods of said first carrier member and that said work pieces are transferred onto said work holder rods of said first carrier member when said two carrier members are engaged with each other and picked on said work holder rods of said second carrier member when said two carriers are separated from each other.

Claim 4

A work carrier assembly, comprising: a first carrier member mounted on a work treating apparatus for supporting a plural number of disc-like work pieces while undergoing a treatment on said apparatus; a second carrier member vertically movable into and out of engagement with said first carrier member for loading and unloading a plural number of work pieces to and from said first carrier member; each one of said first and second carrier members being provided with a plural number of parallel work holder rods each having a plural number of circumferential grooves at intervals along the length thereof for engagement with peripheral edge portions of said work pieces for holding same in predetermined spaced upright positions; work holder rods of said two carrier members being located in vertically staggered positions and shifted relative to each other in a forward or rearward direction in terms of travel direction of said carriers and also in a the vertical direction in such a way that said work holder rods of said second carrier member take lower work support positions than said work holder rods of said first carrier member and that said work pieces are transferred onto said work holder rods of said first carrier member when said two carrier members are engaged with each other and picked on said work holder rods of said second carrier member when said two carriers are separated from each other.

Claim 5

A work carrier assembly as defined in claim 1 or 2, wherein said two carrier members are located in vertically staggered positions to form a pocket concentric with disc-like work pieces to be supported thereon.

Claim 6

A work carrier assembly as defined in claim 3, wherein said work holder rods on said first carrier member are rotatably mounted thereon while said work holder rods on said second carrier member are fixedly mounted thereon.

Claim 7

A work carrier assembly as defined in claim 2, wherein said second carrier member is provided with hooks for lifting same toward and away from said first carrier member.
