Description

  The present invention relates to passenger conveyors such as escalators and moving walkways.

  Passenger conveyors such as escalators and moving walkways connect a number of steps with an endless chain, and the chain is driven by a motor to circulate these many steps. It is transported from the entrance to the exit. This type of passenger conveyor is provided with various safety switches (for example, an inlet switch, a skirt guard switch, etc.) that actuate in an abnormal state and stop the passenger conveyor in an emergency to ensure passenger safety.

  When such a safety switch is activated and the passenger conveyor is in an emergency stop, a maintenance worker visits the installation site of the passenger conveyor to perform a recovery operation. At this time, of the various safety switches provided on the passenger conveyor It was difficult to specify which switch of the throat acted and resulted in an emergency stop, and it often took time for recovery work.

Therefore, for example, in Patent Document 1, an LED 7 segment type indicator is provided on a control panel installed on a skirt guard or the like of a passenger conveyor together with a key switch operated by a maintenance worker. It has been proposed to make it easier for a maintenance worker to confirm a safety switch that has been operated by displaying a corresponding number or the like.

  However, it is not enough to be able to identify which safety switch has been activated in order for the maintenance worker to efficiently perform the restoration work when the passenger conveyor is in an emergency stop. It is desirable that the useful information can be easily confirmed by the maintenance worker. For example, when the passenger conveyor has stopped in an emergency due to a malfunction of the safety switch, information on the safety switch operation history indicating whether the safety switch has been frequently operated in the past can be used to determine the cause of the abnormality. It becomes important information. In addition, when an abnormality occurs due to wear of the article, information for estimating the degree of wear of the article, such as the number of times the passenger conveyor is started up and the operation time, is important information for investigating the cause of the abnormality.

  As described above, in order to improve the efficiency of the work performed by the maintenance worker and reduce the time required for the restoration work, it is desired that the maintenance worker can easily confirm these various pieces of information. If the LED 7 segment type display is used to display information as in the described technology, it is difficult to display a variety of information. In addition, in order to be able to display a variety of information, it is necessary to increase the number of LEDs, and the display becomes larger and it is difficult to secure an installation space. Furthermore, providing such an indicator with the key switch on the operation panel is not practical because the size of the operation panel is further increased.

  The present invention was devised in view of the conventional situation as described above, and allows a maintenance worker to easily confirm useful information for investigating the cause of an abnormality occurring in a passenger conveyor. An object of the present invention is to provide a passenger conveyor that can efficiently perform restoration work at an emergency stop.
