Abstract

PURPOSE:To prevent a cartridge and a mechanism part from being damaged when an earthquake occurs by stopping the operation of an accessor robot transiently when the scale of the earthquake indicates a value less than a regulated value, operation the robot again after the earthquake is over, and informing device abnormality to a host device when it indicates the value exceeding the regulated value. CONSTITUTION:The output of an earthquake detecting sensor 9 is checked when the accessor robot 4 makes access the cartridge, and when the earthquake with the value less than the regulated value is detected, a library controller 6 issues a stoppage instruc tion to the operation of the robot. The robot 4 receiving the stoppage instruction returns a hand extending to a housing rack 2 side to make access the cartridge from the housing rack 2 keeping the cartridge if it holds the cartridge and at a state as it is if not holding the cartridge. After that, the library control 6 monitors the output of the earthquake sensor 9, and restarts the opertion of the robot after the earthquake is over. Also, when the earthquake with the value exce eding the regulated value, the device abnormality is informed to the host device. In such a way, it is possible to prevent the cartridge and the mechanism part damaged even when the earthquake occurs.

In the cartridge library device, an accessor robot takes cartridges in and out of the storage column.
Highly accurate positioning is performed to avoid damage to the cartridge or mechanical parts. However, if an earthquake, which is an external factor, occurs during robot operation, positioning becomes unstable and there is a risk that the cartridge may be damaged. Further, although the mechanism is naturally designed with earthquakes in mind, a large-scale positioning mechanism is required to ensure positioning even during robot operation, which is difficult in terms of cost.

The second level is a level where AC4 can be stopped for a while and operations can be resumed after the earthquake subsides, and the third level is a level of a large-scale earthquake where operations cannot be resumed. As for the control method during an earthquake, if ALC6 detects a level 2 earthquake while the robot is operating, it will immediately issue a command to ADU5 to stop AC4 (at this time, if AC4 had extended its arm to access the CTG) (For example, it is desirable to stop after retracting the arm.) After that, the ALC 6 continues to monitor the earthquake sensor 9 and waits for it to reach level 1. If it does not reach level 1 even after a specified time, for example 2 minutes, It is assumed that the device is abnormal. If level 1 is reached within the specified time, after level 1 is detected, it is confirmed that level 1 continues for a certain period of time, and then a command to continue operation is issued to ADU5.Also, when level 3 is detected, , the device is reported as inoperable to the higher-level CPU, and the device is brought down.
