And a mechanical parking device including: an abnormal state detection unit that detects whether or not an abnormality has occurred in the pallet moving mechanism unit; and an abnormal state detection based on the detection result of the abnormal state in the abnormal state detection unit. When an abnormality is detected in the pallet, when the pallet movement prohibition unit that changes the operating state of the pallet movement mechanism unit to the movement prohibited state in which the movement of the pallet is prohibited, and the movement prohibited state by the pallet movement prohibition unit By inputting the operation signal at the time of abnormality to the operating state of the pallet moving mechanism,
An operation state changing unit that shifts the movement-prohibited state to a movable state in which the pallet can be moved regardless of the abnormality detection result by the abnormal-state detection unit. The movement of the pallet is prohibited regardless of the operation of the pallet, the operation state changing unit allows the pallet moving mechanism to be operated by the operating unit in the movable state, and the operating unit is generated in the pallet moving mechanism. It has a connector part to which a diagnostic tool for reading out information related to an abnormal condition is connected.The diagnostic tool outputs an operation signal at the time of an abnormal condition to the operating condition change part through the connector part when a predetermined operation is performed. The operating state change unit determines whether or not an abnormal operation signal is input from the diagnostic tool connected to the connector unit, and when the abnormal operation signal is input, It is characterized by shifting the operating state of Rett moving mechanism portion movable state.

In the mechanical parking apparatus according to the present invention, the pallet moving mechanism detects an abnormality in the pallet moving mechanism, and the pallet moving mechanism detects an abnormality in the abnormal state detecting unit. Since it has a pallet movement prohibition unit that shifts the operating state of the section to the movement prohibition state,
When an abnormality occurs in the pallet moving mechanism unit, the operating state of the pallet moving mechanism unit shifts to the movement prohibited state and the movement of the pallet is prohibited, so that the safety of the mechanical parking device can be ensured. In addition, when the pallet movement prohibition unit is in the movement prohibited state, the operation signal at the time of abnormality is input, so that the movement state of the pallet movement mechanism is prohibited regardless of the abnormality detection result by the abnormality state detection unit. Since it has an operating state change unit that shifts the state from the movable state to the movable state, even in the movement prohibited state, the operating state of the pallet moving mechanism shifts to the movable state by inputting an operation signal at the time of an abnormality. Can be moved. Therefore, when a maintenance worker who has been informed of the occurrence of an abnormality and wants to move the pallet to confirm the abnormal state of the abnormal place or the contents of the abnormal state, or to move the pallet for operation in the abnormal state, By inputting the operation signal, the pallet can be easily moved. Further, since the movement prohibited state is maintained unless the operation signal at the time of abnormality is input, the safety of the mechanical parking device at the time of abnormality occurrence is not impaired.

Further, the maintenance staff can move the pallet while ensuring the situation around the mechanical parking device, and can ensure the safety when moving the pallet in the movable state.
Furthermore, the pallet can be moved quickly in the movable state.

Further, in the present invention, the operation section has a connector section to which a diagnostic tool for reading out information regarding an abnormal state occurring in the pallet moving mechanism section is connected, and the diagnostic tool is a predetermined one. When the abnormal operation signal is input from the diagnostic tool connected to the connector section, the operating state change section outputs the abnormal operation signal to the operating state change section via the connector section. When the abnormal operation signal is input, the operating state of the pallet moving mechanism section is shifted to the movable state.
As described above, since the operation unit has the connector unit to which the diagnostic tool for reading the information regarding the abnormal state occurring in the pallet moving mechanism unit is connected, connect the diagnostic tool to the connector unit. As a result, the state in which the information regarding the abnormal state occurring in the pallet moving mechanism is ready to be read. Therefore, it is possible to easily acquire information about an abnormal state such as an abnormal portion or an abnormal content with an extremely simple configuration having a connector portion to which a diagnostic tool is connected. In addition, since a diagnostic tool for reading out information about the status of abnormalities occurring in the pallet moving mechanism section can be used to input an operation signal at the time of abnormality to the operation status change section, maintenance personnel can connect to the connector section. By operating the diagnostic tool after connecting the diagnostic tool, the operating state of the pallet moving mechanism can be changed from the movement prohibited state to the movement enabled state while staying at the position of the operation unit. The migration of can be done quickly.

Further, it is preferable that the operating state changing unit shifts the operating state of the pallet moving mechanism unit from the movable state to the movement prohibited state by inputting an abnormal operation end signal. In this way, the operation state changing unit shifts the operation state of the pallet moving mechanism from the movable state to the movement prohibited state when the operation end signal at the time of abnormality is input, and the maintenance staff moves the pallet. When the user wants to shift to the movement prohibition state after the failure or after the abnormality is recovered, the movement prohibition state can be easily changed by inputting the abnormal operation end signal. Since the abnormal-time operation end signal is different from the abnormal-time operation signal, it is possible to prevent an erroneous operation of accidentally shifting to the movement prohibited state.

Further, the diagnostic tool outputs an operation end signal at the time of abnormality to the operating state changing section via the connector section when a predetermined operation is performed, and the operating state changing section is connected to the connector section. It is preferable to determine whether or not an abnormal operation end signal has been input from, and to shift the operating state of the pallet moving mechanism from the movable state to the movement prohibited state when the abnormal operation end signal is input. .
If such a configuration is adopted, it is possible to input the operation end signal at the time of abnormality to the operation state changing unit by using a diagnostic tool for reading information regarding the state of abnormality occurring in the pallet moving mechanism unit. , The maintenance staff operates the diagnostic tool after connecting the diagnostic tool to the connector section, so that the operation state of the pallet moving mechanism section is changed from the movable state to the movement prohibited state while being at the position of the operating section. Therefore, it is possible to quickly shift to the movement prohibited state.

The abnormal state detector stores the detected abnormal state as abnormal information when an abnormality is detected in the pallet moving mechanism, and stores the abnormal state in a diagnostic tool connected to the connector. It is preferable to output the abnormality information. In this way, the abnormal state detection unit
When an abnormality is detected in the pallet moving mechanism section, the detected abnormality state is stored as abnormality information, and the abnormality information is output to the diagnostic tool connected to the connector section as information relating to the abnormality state, so that the abnormality occurrence location is detected. Alternatively, the information regarding the abnormal state such as the content of the abnormality is surely stored and output to the diagnostic tool. Therefore, it is possible to accurately and quickly acquire the information on the above-mentioned abnormal state.

Further, it is preferable to further include an informing unit for informing that the operating state of the pallet moving mechanism has been changed to the movable state by the operating state changing unit.
When such a configuration is adopted, it is possible to notify a person in the vicinity of the mechanical parking device that the operating state of the pallet moving mechanism has been moved to the movable state, and The safety can be improved.
