Abstract
PURPOSE: To prevent a work from being damaged by seismic shock, by stopping the grinder after separating a grindstone from the work when the preliminary tremor of an earthquake is detected.
CONSTITUTION: The work 5 is supported by centers 3a, 3b and is reciprocated by a feed mechanism 6 while being rotated by a rotating mechanism 4. The grinstone 1 is rotated by a rotating mechanism 2. When a primary wave sensor 9 detects 10 the preliminary tremor of an earthquake, a one-shot multivibrator 11 generates a pulse 12, thereby actuating a separating-contacting device 15 through a control panel 7 to separate the grindstone 1 from the work 5. A delay circuit 13 feeds out a pulse 14 with a delay behind the pulse 12, and the control panel 7 stops the rotating mechanism 2, 4 and the feed mechanism 6 when it is fed with the pulse 14.
