Abstract

A conveyance device for a heat treatment device presses a conveyed body to convey the conveyed body in a linear direction, and includes a cylinder mechanisms having a retractable rod that presses the conveyed body, in which: an abutting member is disposed at a tip part of the rod of the cylinder mechanism so that the abutting member abuts locations, which are different from each other in a circumferential direction, on an outer peripheral surface of the conveyed body; a guide rail configured to guide the abutting member is provided; and the abutting member is provided with a traveling roller that travels on the guide rail.

First claim

What is claimed is:

1. A conveyance device for a heat treatment device that presses a conveyed body to convey the conveyed body in a linear direction, the conveyance device comprising:
a cylinder mechanism which includes a retractable rod that presses the conveyed body, wherein:
a pair of abutting members are disposed at a tip part of the rod of the cylinder mechanism so that the pair of abutting members abut two locations, which are separate from each other in a circumferential direction, on an outer peripheral surface of the conveyed body;
a guide rail configured to guide the pair of abutting members; and
each abutting member includes a traveling roller that travels on the guide rail.

2. The conveyance device for a heat treatment device according to claim 1 ,
wherein the conveyed body is disc-shaped such that the outer peripheral surface is circular, and the pair of abutting members are arranged to abut two different circumferential locations on the circular outer peripheral surface of the disc-shaped conveyed body.

3. The conveyance device for a heat treatment device according to claim 1 , wherein:
the guide rail is intermittently arranged via a gap in a length direction of the guide rail;
each abutting member includes a plurality of the traveling rollers disposed in a traveling direction of the traveling roller; and
the plurality of traveling rollers are arranged so that a distance between two traveling rollers located at outermost portions of the plurality of traveling rollers becomes longer than a length of the gap.

4. The conveyance device for a heat treatment device according to claim 2 , wherein:
the guide rail is intermittently arranged via a gap in a length direction of the guide rail;
each abutting member includes a plurality of the traveling rollers disposed in a traveling direction of the traveling roller; and
the plurality of traveling rollers are arranged so that a distance between two traveling rollers located at outermost portions of the plurality of traveling rollers becomes longer than a length of the gap.

5. The conveyance device for a heat treatment device according to claim 1 ,
wherein an adjusting mechanism that adjusts a length of the abutting member is disposed at a tip part of each abutting member.

6. The conveyance device for a heat treatment device according to claim 2 ,
wherein an adjusting mechanism that adjusts a length of the abutting member is disposed at a tip part of each abutting member.

7. The conveyance device for a heat treatment device according to claim 3 ,
wherein an adjusting mechanism that adjusts a length of the abutting member is disposed at a tip part of each abutting member.

8. The conveyance device for a heat treatment device according to claim 4 ,
wherein an adjusting mechanism that adjusts a length of the abutting member is disposed at a tip part of each abutting member.

9. A heat treatment device comprising:
a heating device that heats a treatment object;
a conveyed body on which the treatment object is placed;
a conveyance chamber configured to convey the conveyed body, on which the treatment object is placed, to the heating device; and
the conveyance device for a heat treatment device according to claim 1 .
