Glass-plate working apparatus

A glass-plate working apparatus comprising:

• a glass-plate transporting device;
• two grinding worktables which move independently of each other in a Y-axis direction perpendicular to a direction of transporting a glass plate by the glass-plate transporting device and which are arranged in the transporting direction of the glass plate;
• and
• a grinding head which moves in an X-axis direction parallel to the transporting direction,
• each of the two grinding worktables having a suction pad for sucking the glass plate on an upper surface thereof and a table base on which the suction pad is detachably mounted,
• wherein the two grinding worktables are adapted to alternately repeat an operation of grinding a held glass plate by the grinding head and an operation of, during the grinding, discharging a ground glass plate and receiving and holding a next glass plate, and the grinding head is adapted to move in an X-Y planar coordinate system in a changing manner with the grinding worktable holding the glass plate and effect grinding on a continual basis.

A glass-plate working apparatus comprising:

• two grinding worktables which undergo angularly controlled rotation independently of each other and move in a Y-axis direction perpendicular to a transporting direction of a glass plate;
• and
• a grinding head which moves in a planar coordinate system alternately in cooperation with each of the two grinding worktables,
• each of the two grinding worktables having a suction pad for sucking the glass plate on an upper surface thereof and a table base on which the suction pad is detachably mounted,
• the two grinding worktables being arranged in series in the transporting direction of the glass plate,
• the grinding head being adapted to move in an X-axis direction which is the transporting direction of the glass plate, so as to be disposed alternately at a position corresponding to each of the two grinding worktables,
• wherein the two grinding worktables alternately repeat operation in which while one of the grinding worktables, while holding a glass plate, is effecting the grinding of the glass plate by the grinding head, another one of the grinding worktables effects an operation of discharging the glass plate and receiving a next glass plate, to thereby allow the grinding head to proceed with grinding on a continual basis.
