For example, the lower speed reducer 4a is composed of a push button. Two poles are arranged side by side in the width direction of the step at the upper entrance 2b. An upper speed reduction device 4b is provided on the upper surface of the pole. For example, the upper speed reduction device 4b is composed of a push button.

  A first lower detection device 5a is provided above the pole of the lower entrance 2a. For example, the first lower detection device 5a includes a transmissive photoelectric sensor. The first lower detection device 5a has a function of detecting a user who passes through the lower entrance 2a. A first upper detector 5b is provided on the upper part of the pole of the upper entrance 2b. For example, the first upper detection device 5b includes a transmissive photoelectric sensor. The first upper detection device 5b has a function of detecting a user passing through the upper entrance 2b.

  In the lower part of the passenger conveyor, the lower part of the balustrade 1 on both sides is provided with a second lower detector 6a. For example, the second lower detection device 6a includes a transmissive photoelectric sensor. The 2nd lower part detection apparatus 6a is provided with the function to detect the user just before boarding on the step arrange | positioned at the lower part of a passenger conveyor. In the upper part of the passenger conveyor, a second upper detector 6b is provided at the lower part of the balustrade 1 on both sides. For example, the second upper detection device 6b includes a transmissive photoelectric sensor. The second upper detection device 6b has a function of detecting a user immediately before getting into a step disposed on the upper part of the passenger conveyor.

  The driving machine 3, the lower speed reduction device 4a, the first lower detection device 5a, the second lower detection device 6a, the upper speed reduction device 4b, the first upper detection device 5b, and the second upper detection device 6b are connected to the speed control device 7. The For example, the speed control device 7 is provided in the vicinity of the upper entrance / exit 2b in the passenger conveyor. The speed control device 7 is configured according to the operating states of the lower speed reduction device 4a, the first lower detection device 5a, the second lower detection device 6a, the upper speed reduction device 4b, the first upper detection device 5b, and the second upper detection device 6b. A function of controlling the drive unit 3 is provided. By this control, the speed of the step is controlled.

Next, the operation of the passenger conveyor when the passenger conveyor is in the ascending operation will be described with reference to FIG.
FIG. 2 is a flowchart for explaining the operation of the passenger conveyor in the first embodiment of the present invention.

  When the passenger conveyor is in the ascending operation, the lower entrance / exit 2a is the entrance. On the other hand, the upper entrance / exit 2b becomes an exit. In this case, when the user passes through the lower entrance 2a, the first lower detection device 5a detects the user. Based on the detection, the speed control device 7 controls the drive unit 3 so that the passenger conveyor is activated and accelerated.

  Thereafter, when the user operates the lower reduction gear 4a in step S1, the lower reduction gear 4a outputs a deceleration signal. The deceleration signal is input to the speed control device 7.

  Then, it progresses to step S2 and the speed control apparatus 7 decelerates the drive machine 3 for a fixed time using a deceleration signal as a trigger. Following the deceleration, the step is decelerated. The predetermined time is set based on the installation position of the lower reduction gear 4a, the distance to the entrance of the passenger conveyor, the deceleration, and the like.

  Then, it progresses to step S3 and the speed control apparatus 7 determines whether the 2nd lower part detection apparatus 6a detected the user. That is, the speed control device 7 determines whether or not a user detection signal is input from the second lower detection device 6a.

  When the second lower detection device 6a detects a user, step S3 is repeated. On the other hand, when the 2nd lower part detection apparatus 6a has not detected the user, it progresses to step S4.

  In step S4, the speed control device 7 returns the speed of the driving machine 3 to the normal speed. Following the speed, the step speed returns to the normal speed. Then, it progresses to step S5 and the speed control apparatus 7 determines whether fixed time passed. The predetermined time is set based on the length of the passenger conveyor, the normal speed, the acceleration / deceleration, and the like.

  If the certain time has not elapsed, step S5 is repeated. If the predetermined time has elapsed, the process proceeds to step S6. In step S6, the speed control device 7 decelerates the driving machine 3 for a certain time. The predetermined time is set to a minimum time required for the user to get off based on acceleration / deceleration and the like.

  Then, it progresses to step S7 and the speed control apparatus 7 returns the speed of the drive machine 3 to a normal driving | operation. Following the speed, the step returns to the normal speed. Thereafter, a series of speed control ends.

  According to the first embodiment described above, when the lower speed reduction device 4a is operated, the speed control device 7 reduces the speed of the drive unit 3 from the normal speed based on a predetermined time plan, and thereafter Return to normal speed, then decelerate, then return to normal speed.

  In this case, the step is decelerated at the timing when the user gets on the passenger conveyor. The step returns to normal speed after the user gets on the passenger conveyor. The step is decelerated at the timing when the user gets off the passenger conveyor. The step returns to normal speed after the user gets off the passenger conveyor.

  For this reason, the user can easily get on and off the passenger conveyor while maintaining the convenience of the passenger conveyor.

  As an example, the case where the normal speed of a passenger conveyor shall be 30 m / min and the speed at the time of deceleration shall be 20 m / min is demonstrated. In this case, when returning to the normal speed in the middle, the user can reach the exit in about 2/3 of the time when the vehicle continues to decelerate from the time of getting on until getting off. That is, the longer the passenger conveyor is, the more time is shortened.

  In addition, the user who needs to decelerate the passenger conveyor when getting on and off is less likely to walk the steps. For this reason, even if it does not identify a user, it is possible to easily set the time from when the user gets in until it gets off.

  Further, while the second lower detection device 6a is detecting the user, the driving machine 3 maintains the decelerated state. For this reason, even if the user stops before the step and measures the timing of getting in, the step does not return to the normal speed.

  Further, when the second lower detection device 6a has not detected the user for a certain period of time after the lower speed reduction device 4a is operated, the speed of the drive unit 3 returns to the normal speed. For this reason, when the user who operated the lower speed reducer 4a does not get on the passenger conveyor, the step can be returned to the normal speed.

  When the passenger conveyor is in the descending operation, the upper entrance 2b is the entrance. On the other hand, the lower entrance 2a becomes an exit. In this case, the upper speed reduction device 4b, the first upper detection device 5b, and the second upper detection device 6b are the same as the lower speed reduction device 4a, the first lower detection device 5a, and the second lower detection device 6a in which the passenger conveyor is in the ascending operation. You can use it. In this case as well, the user can easily get on and off the passenger conveyor while maintaining the convenience of the passenger conveyor.
