摘要:
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 device 1 for handling a quartz glass crucible 5, the device including: a frame 4 having a beam 2 extending in a horizontal direction and a pair of arms 3 protruding from the beam 2 in a direction perpendicular to a central axis line direction of the beam 2 such that at least one of the arms 3 is able to move in the central axis line direction of the beam 2; a pair of sandwiching means 6 assembled with the pair of the arm 3 to face each other, for sandwiching a body 50 of the quartz glass crucible 5 in a radial direction of the crucible; engagement means 7 provided adjacent to each sandwiching means 6 and formed by a pair of tongues 70 movable to approach or be separated from each other in a central axis direction of the crucible, for sandwiching and holding the quartz glass crucible 5 therebetween in the central axis direction of the crucible; and driving means 8 for causing the sandwiching means 6 and the engagement means 7 to reciprocate along the arm 3. The present invention also provides a method of handling a quartz glass crucible using such a device 1 as described above.

An object of the present invention is to provide a crane device suitable for handling a wrapped crucible, which crane device is capable of realizing mechanical handling of the wrapped crucible by way of a machine without manual work. In view of this, the present invention provides a crane device adapted to be capable of making reciprocal movements along a path between a position above a lifting-up point where a wrapped quartz glass crucible is placed and another position above a putting-down point where a packing container is placed and ascending to/descending from the path at each of the lifting-up point and the putting-down point, the crane device having: four arms extending in the ascend-descend direction and disposed at apexes of a quadrangle such that two arms paired on a diagonal line of the quadrangle are movable to advance to/separate from each other; and a claw provided at a rear end of each arm to extend in the advancing direction of the arm.
