Definitions

  • This invention relates to a device for automatically operating a passenger conveyor having a first detector for detecting approach of passengers and a second detector for detecting passage of the passengers, in accordance with detection conditions of the above-described detectors.
  • the reflection type passenger detector using reflection of an energy wave easily varies in its detection distance depending on the detection objects and the environmental conditions, and the following problems occur due to the occurrence of failures.
  • the steps stop during standby, it is possible that passengers get on from the gate side in the opposite direction when the detector which is at the gate side in the opposite direction to the conveying direction fails.
  • the steps are actuated in the opposite direction while the passenger from the opposite direction is walking on the steps, and there is a possibility that the passenger falls down.
  • the passenger riding thereon from the normal direction cannot be detected due to the failure of the detector, there also arises the problem that while the passenger is walking on the steps, the passenger from the opposite direction is detected and the steps are suddenly actuated.
  • the reflection type passenger detector not only detects the users of the passenger conveyor, but also people and the like passing around it, and therefore it is prone to cause the problems as described above.
  • JP 11-292447 A describes that as a first detector for detecting approach of a passenger, a reflection type passenger detector using reflection of an energy wave is used, and as a second detector for detecting a passenger passing a position just before a step of the passenger conveyor, a transmission type passenger detector for projecting a light beam is used.

  • the first detecting element is a doorway front primary detecting element which is arranged to detect any passenger approaching the gate side of the escalator.
  • the doorway primary detecting element is arranged closer to the entrance of the escalator in order to detect passengers who are in fact entering the escalator itself.
  • the doorway front primary detecting element detects a passenger
  • the escalator is started together with an operation timer in order to stop the escalator when the operation timer is reset.
  • an operation timer is started to allow monitoring of the operation time after which the escalator is again stopped.
  • This invention is made to eliminate the above-described problems, and has its object to provide an automatic operation device for a passenger conveyor which does not cause trouble when a passenger rides thereon even when a failure occurs to the detector, and to make it possible to increase convenience and maintainability.
  • An automatic operation device for a passenger conveyor of the present invention stops actuation of steps when a first detector does not detect a passenger and the second detector detects the passenger, while the passenger conveyor is on standby (is stopping).
  • the automatic operation device for the passenger conveyor of the present invention operates the steps continuously at a rated speed when the first detector does not detect a passenger and the second detector detects the passenger while the passenger conveyor is on standby (is operating at a low speed).
  • the automatic operation device for the passenger conveyor of the present invention uses such a type of detector as detects a passenger by a reflection wave of an energy wave as the first detector, and as the second detector, such a type of detector as detects a passenger by cutoff of an energy beam is used.
  • the automatic operation device for the passenger conveyor of the present invention operates the steps continuously at a rated speed when a state in which the second detector detects a passenger before the moving speed of the steps actuated as a result of the first detector detecting the passenger reaches a specified speed occurs successively for the predetermined number of times or more.
  • the automatic operation device for the passenger conveyor of the present invention returns to the automatic operation again when the first detector detects a passenger after the steps shift to the continuous operation.
  • the automatic operation device for the passenger conveyor of the present invention outputs a malfunction signal outside and records the history of the malfunction judgment when the first detector does not detect a passenger and the second detector detects the passenger, or when a state in which the second detector detects a passenger before the steps reach a specified speed after the first detector detects the passenger occurs successively for the predetermined number of times or more.

  • step S1 a count time N of the low speed ride counter 17 is set at zero.
  • step S2 the passenger conveyor is in a standby (stopping) state.
  • step S3 the passenger detection failure judging means 12 judges whether the upper first detector 6 detects a passenger, and when it does not detect the passenger, a command is given to proceed to step S4, and the passenger detection failure judging means 12 judges whether the upper second detector 7 detects a passenger. When the upper second detector 7 does not detect the passenger, the passenger detection failure judging means 12 judges that there is no passenger, and a command is given to return to step 2.
  • step S5 When the upper second detector 7 detects a passenger, a command is given to proceed to step S5, and the actuation judging means 10 outputs an actuation stopping command to stop actuation of the steps via the driving means 11.
  • step S6 the passenger detector failure judging means 12 outputs a malfunction signal to a monitor panel, a remote monitoring center, and an alarm 13 such as a failure indicator, and records the malfunction judgment into the historic memory 14.
  • steps S2 to S5 define the actuation judging means 10.
  • actuation of the passenger conveyor is stopped when the first detector 6 does not detect a passenger and the second detector 7 detects the passenger while the passenger conveyor is stopping, and therefore when the first detector 6 is incapable of detecting a passenger due to failure or the like, the passenger conveyor can be prevented from being actuated after the passenger gets on the passenger conveyor which is stopping.
  • step S3 when it is judged that the first detector 6 detects a passenger in step S3, a timer (not shown) is started in step S7, and a standby releasing command for the passenger conveyor is outputted in step S8.
  • step S9 it is determined that the second detector 7 detects the passenger.
  • a command is given to wait until a set time elapses in step S10, and after the set time elapses, a stop command for the passenger conveyor is outputted in step S11 and a command is given to return to step S2.
  • step S9 when the second detector 7 detects a passenger in step S9, a command is given to proceed to step S12, and the ride time speed judging means 16 judges whether the speed of the steps is a specified speed or higher from the output of the speed detector 15. When the speed is lower than the specified speed, a command is given to proceed to step S13, and it is judged whether the count time N of the low speed ride counter 17 is 5 or more. When it is less than 5 times, one is added to the time N, then a command is given to shift to an automatic operation in step S16, and to return to step S2.
  • step S17 defines the malfunction signal 10.
  • the passengers can be prevented from getting on the step in the state in which the steps are not sufficiently accelerated due to reduction of the detection distance of the first detector 6 or the like.
  • the malfunction signal is outputted to, for example, the warning panel, the remote warning center or the failure display device and the like, and the history of the malfunction judgment is stored, it possible to notice a failure and reduction in the detecting ability of the first detector as soon as possible and enhance maintainability, and to confirm the above-described history at the time of maintenance or the like after the passenger conveyor returns to automatic operation.
  • step S12 When it is judged that the speed of the steps is the specified speed or higher in step S12, the count number N of the counter 17 is returned to zero in step S15, and the automatic operation is carried out in step S16.
  • the condition that the speed of the steps when the second detector 7 detects a passenger is the specified speed or higher, but the condition may be the elapsed time from the time at which the first detector 6 detects a passenger until the time at which the second detector 7 detects the passenger.
  • the passenger conveyor of a second embodiment has a low speed operation-on-standby type automatic operation function. Namely, the passenger conveyor is on standby with the steps moving at a low speed when there is no passenger, and when it detects a passenger, it starts an automatic operation, whereby silence and energy conservation are realized.
  • the count time N of the low speed ride counter 17 is set at zero in step S1.
  • step S21 the passenger conveyor is brought into a standby (low speed) state.
  • step S3 it is judged whether the first detector 6 detects a passenger, and when it does not detect the passenger, a command is given to proceed to step S4, and it is judged whether the second detector 7 detects the passenger.

  • step S24 a command is given to wait until the first detector 6 detects a passenger in step S24, and when the first detector 6 detects a passenger, a command is given to return to automatic operation in step S25 and to return to step S21.
  • steps S22, S24, and S25 define the automatic operation returning means.
  • step S26 a standby command for the passenger conveyor is outputted.
  • the malfunction signal is outputted to indicate this and the history of the malfunction judgment is stored, therefore making it possible to notice a failure and reduction in the detection ability of the first detector 6 as soon as possible and to increase maintainability, and alsomaking it possible to confirm the history of the shift to the continuous operation during maintenance and the like even after returning to the automatic operation.
  • the first detector 6 is one using a reflection type passenger detector, and this is because the reflection type passenger detector can detect approach of a passenger from a position away from the gate side.
  • the first detector 6 is not limited to the reflection type passenger detector, and other types of detectors are sufficiently useful as long as they can detect a passenger approaching the gate side.
  • the automatic operation device for the passenger conveyor is useful as the countermeasure against the case in which a failure occurs to the detection of the first detector when the first detector for detecting a passenger approaching the gate side of the passenger conveyor, and the second detector for detecting a passenger passing just before the steps are provided.
  • This is especially suitable for the case using the reflection type passenger detector in which the first detector is considered to vary in the detection distance due to the condition of the environment and the detected object.
