Abstract
An object of the present invention is to provide a crucible handling device that can firmly sandwich and reliably move a quartz glass crucible under a clean environment and a method of handling a quartz glass crucible using the crucible handling device. The present invention provides a crucible handling devicefor handling a quartz glass crucible, the device including: a framehaving a beamextending in a horizontal direction and a pair of armsprotruding from the beamin a direction perpendicular to a central axis line direction of the beamsuch that at least one of the armsis able to move in the central axis line direction of the beama pair of sandwiching meansassembled with the pair of the armto face each other, for sandwiching a bodyof the quartz glass cruciblein a radial direction of the crucible; engagement meansprovided adjacent to each sandwiching meansand formed by a pair of tonguesmovable to approach or be separated from each other in a central axis direction of the crucible, for sandwiching and holding the quartz glass crucibletherebetween in the central axis direction of the crucible; and driving meansfor causing the sandwiching meansand the engagement meansto reciprocate along the arm. The present invention also provides a method of handling a quartz glass crucible using such a deviceas described above.
