  Conventionally, a passenger conveyor device that changes the moving speed of a tread according to the moving time of a passenger has been proposed as disclosed in, for example, Patent Document 1.

  The passenger conveyor device described in Patent Document 1 is configured to install at least two detectors at intervals in the passenger movement direction in order to detect the movement time of the passenger, and detect the time during which the passenger passes between them. The travel time of the passenger is obtained from this time and the distance between the two detectors, and the travel speed of the tread is changed from the travel time of the passenger.

JP 2002-104761 A

  In the passenger conveyor apparatus described in Patent Document 1, two detectors that are always installed at intervals in the passenger movement direction are required to detect one passenger.

  However, even if two detectors are used, it becomes easy to be affected by the shake of the passenger's hand, the size of the baggage, and the like, and it is difficult to detect the accurate travel time of the passenger.

  One object of the present invention is to provide a passenger conveyor device that can accurately detect the travel time of passengers.

  Another object of the present invention is to provide a passenger conveyor device that can accurately detect the movement time of a vulnerable walking person and set an optimum tread board moving speed.

  In order to achieve the above object, the present invention provides passenger movement time detection means on both sides in the width direction for detecting the movement time from stepping on the foot of a passenger walking in the boarding / exiting floor in the boarding direction to kicking up. Provided is a control device for changing the moving speed of the tread by comparing the moving time detected by the moving time detecting means with the reference moving time, and the passenger moving time detecting means on both sides of the passenger beam moving time detecting means in the direction changing portion of the moving handrail It was installed so as to cross and extend at the center in the width direction before reaching, and the passenger movement time detection means on both sides were constituted by independent circuits.

  In general, the time required for a passenger to step on the landing foot to be lifted off the landing is naturally slower for elderly people and physically disabled persons than for healthy persons, and is faster for young healthy persons. Therefore, the travel time from the stepping on of the passenger's foot to the kick-up is detected, and if it is slow compared with the reference travel time, the travel speed of the tread is slowed down, and if it is fast, the current tread travel speed is Is maintained or accelerated within an acceptable range. The travel time from the stepping of the passenger's foot to the kicking is measured by an on / off signal of each passenger travel time detection means having an independent circuit configuration, and the travel speed of the tread is determined based on the longer travel time. Since it can be set, it is not necessary to cross two detectors installed with a predetermined interval as in the prior art, and the moving speed of the tread can be set with priority given to weak walkers.

  Further, since the passenger movement time detecting means detects the movement of the passenger's foot, the movement time from the stepping of the passenger's foot to the kicking up is detected without being influenced by the swing of the passenger's hand. Therefore, if the baggage is within the passenger's stride, the movement speed of the passenger can be detected accurately without being affected by the baggage.

  ADVANTAGE OF THE INVENTION According to this invention, the passenger conveyor apparatus which can detect a passenger's moving time accurately, especially can detect the moving time of a weak walking person accurately, and can set the optimal tread board moving speed can be obtained.

  An embodiment of a passenger conveyor device according to the present invention will be described below based on the escalator shown in FIGS.

  In general, the escalator 1 includes a frame 4 supported across the upper floor 2 and the lower floor 3, a step 5 having a step board on the upper surface, and a balustrade 6 erected on both sides in the moving direction of the step 5. It has a moving handrail 7 which is guided and moved by the periphery of the balustrade 6 and boarding / exiting floors 8A and 8B for getting on and off the step 5.

  A plurality of the steps 5 are connected to the step chain 9 in an endless manner, and are circulated and guided by guide rails (not shown) provided on the frame body 4. The step chain 9 is wound around a drive sprocket 10 supported on one side in the longitudinal direction of the frame body 4 and a driven sprocket 11 supported on the other side in the longitudinal direction of the frame body 4. It has been. The drive sprocket 10 is driven by a drive device 12 installed in the vicinity, and the moving handrail 7 is also driven in synchronization with the step 5 by the power of the drive device 12.

  The balustrade 6 includes a balustrade panel 13 erected on both sides in the moving direction of the step 5, a skirt guard 14 that partitions the balustrade panel 13 and the step 5, an inner deck cover 15 that covers the skirt guard 14, and An outer deck cover 16 that covers the outer side of the base of the balustrade panel 13, an end cover that covers the terminal portions of the skirt guard 14, the inner deck cover 15, and the outer deck cover 16 and that has an entrance through which the moving handrail 7 enters and exits. 17 and a balustrade component member.

  A light reflection type sensor 18A that emits a detection beam that is a passenger movement time detection means and emits a detection signal to the left and right end cover 17 that is a balustrade component of the escalator 1 configured as described above. 18B is attached. The light reflection sensors 18A and 18B are installed so as to emit a detection beam so as to be substantially parallel to the floor surface of the passenger floor 8A (8B), and can detect all the passengers M1 passing therethrough. The detection beam is installed to radiate in a direction intersecting the passenger traveling direction. Specifically, the detection beam intersects at the center in the width direction before reaching the direction changing portion 7E of the moving handrail 7, and the light reflection sensors 18A and 18B are installed so as to extend about 30 cm away from the intersection, and The light reflection sensors 18A and 18B on the both sides are constituted by independent circuits.

  Therefore, detection signals from the light reflection sensors 18A and 18B are respectively input to the control device 19 installed in the vicinity of the driving device 12 and are calculated in the control device 19. As a result of calculation in the control device 19, priority is given to a detection signal with a longer passenger movement time (detection time is longer), and the drive device 12 is instructed to change the movement speed of the step 5 based on this detection signal. I am doing so.

  As described above, since the light reflection type sensors 18A and 18B are provided on the end cover 17, the light reflection type in which the foot of the passenger M1 trying to get into the escalator 1 from the center in the width direction is formed by an independent circuit. When the detection beams from the sensors 18A and 18B are blocked, the reflected light returns to the light reflection sensors 18A and 18B, and a detection signal is output. FIG. 4 shows an example of detection signals from the light reflection sensors 18A and 18B. In FIG. 1, the position where the right foot of the passenger M1 crosses the detection beam about 30 cm away from the beam intersection of the detection beam from the light reflection sensor 18B is b1, and the left foot of the passenger M1 is the detection beam from the light reflection sensor 18B. The position crossing the detection beam in front of the beam intersection is point b2, the position where the left foot of the passenger M1 crosses the detection beam about 30 cm away from the beam intersection of the detection beam from the light reflection type sensor 18A is point a1, and the position of the passenger M1 The position where the right foot crosses the detection beam in front of the beam intersection of the detection beam from the light reflection type sensor 18A is point a2, and in FIG. 4, the upper side is a detection signal from the light reflection type sensor 18B, and the lower side is a light reflection type. Displayed as a detection signal by the sensor 18A.

  In FIG. 4, the reference movement time is set so that the movement time Tb1 detected by the light reflection type sensor 18A and the movement time Tb2 detected by the light reflection type sensor 18B are the same, and is substantially the same as the movement times Tb1 and Tb2. If so, it is determined that the person is a normal healthy person, and the control device 19 instructs the drive device 12 to drive the step 5 at the standard speed. Compared to the movement times Tb1 and Tb2, if the movement times To1 and To2 are longer than the movement times Tb1 and Tb2, it is determined that the elderly person or the physically handicapped walking weak person, and the control device 19 sends a step 5 to the driving device 12. To operate at low speed. On the contrary, if the movement times Ty1 and Ty2 are shorter than the movement times Tb1 and Tb2 compared to the movement times Tb1 and Tb2, it is determined that the person is a young person, and the control device 19 causes the driving device 12 to move the step 5 at the standard speed. Command to drive or drive at a higher speed allowed than the standard speed.

  When a difference occurs in the detection time by the light reflection type sensors 18A and 18B, for example, To1> To2, the control device 19 gives priority to the detection signal having the longer detection time and issues a command to the drive device 12. This is advantageous for weak walkers.

  From the above, when the passenger is detected, the movement of the step 5 is paused, and even if automatic operation is performed to drive the step 5 at the reference speed, the type of the passenger on board is judged and driving at an accurate driving speed is performed. Can be started. Needless to say, even in a normal operation in which the step 5 is always operated at the reference speed even when it is quiet, it is possible to determine the type of the passenger and change the driving speed to an appropriate driving speed.

  Further, since the light reflection type sensors 18A and 18B are provided on the end cover 17, the light reflection type sensors 18A and 18B can detect the movement of the passenger's foot, and as a result, are influenced by the shaking of the passenger's hand. Thus, it is possible to accurately detect the moving speed of the passenger.

  Furthermore, when the length dimension in the traveling direction of the baggage is larger than the dimension between the backs of the passengers, the detection time becomes longer when the baggage is detected by the light reflection type sensors 18A and 18B. In some cases, it is determined that the person is an elderly person or a physically handicapped person, and the moving speed of the step 5 is switched from the standard speed to the low speed driving. Therefore, it becomes a low-speed driving that is meaningless for healthy people and young people.

  In order to eliminate such inconvenience, in the present embodiment, the installation positions of the light-reflective sensors 18A and 18B, particularly the installation height, is set to a position that radiates the feet of passengers. More specifically, when passengers with baggage and passengers without baggage are detected in the same way, it is necessary to correctly determine whether the person is an elderly person, a physically handicapped person, or another person. It is desirable to install the light-reflective sensors 18A and 18B within a range of 5 cm to 20 cm above the floor surface of (8B). That is, when a healthy person walks, the height of the heel when stepping on the foot is about 3 cm from the ground, and if the light-reflective sensors 18A and 18B are installed at a height of 5 cm or less, the passenger There is a possibility that the foot on the stepping side cannot be detected. Therefore, the installation height of the light reflection type sensors 18A and 18B is set to 5 cm or more. In addition, when the light-reflective sensors 18A and 18B are installed at a height of 20 cm or more from the floor surface, the length dimension in the traveling direction of the baggage is larger than the dimension between the passenger's backs and the passengers can be accurately moved. There is a possibility that it cannot be detected. For this reason, it is desirable to install the light reflection sensors 18A and 18B within a range of 5 cm to 20 cm above the floor surface of the passenger floor 8A (8B). The light reflection sensors 18A and 18B are disposed on the escalator 1. Considering the provision of the end cover 17 which is a balustrade component, it is most effective to install it at a position 15 cm above the floor surface of the passenger floor 8A (8B).

  Thus, by installing the light reflecting sensors 18A and 18B at a position 15 cm above the floor of the passenger floor 8A (8B), the length in the traveling direction is temporarily larger than the dimension between the passenger's back and abdomen. Even when the baggage is detected, the length dimension in the traveling direction of the baggage at 15 cm above the floor is almost within the stride of the passenger, so that it is almost the same as detecting the stride of the passenger.

  Therefore, even if the passenger has a baggage larger than the size between the passenger's backs, the moving speed can be detected with high accuracy. Then, as shown by a solid line in FIG. 5, the detection signal has substantially the same detection signal pattern as in FIG.

  That is, a passenger with baggage is measured by the light reflection sensors 18A and 18B, and if the detection signal ON time is substantially the same as the reference movement time Tb1, it is determined that the passenger is a normal healthy person and is driven from the control device 19. The apparatus 12 is instructed to operate the moving speed of the step 5 at the standard speed. Compared with the reference movement time Tb1, if the movement time To1 is longer than the reference movement time Tb1, it is determined that the person is an elderly person or a physically handicapped person, and the moving speed of the step 5 from the control device 19 to the drive device 12 is determined. To operate at low speed. On the other hand, if the movement time Ty1 is shorter than the reference movement time Tb1 compared to the reference movement time Tb1, it is determined that the person is a young person, and the control device 19 sets the step 5 to the standard speed or the standard speed with respect to the drive device 12. Command to drive at a higher speed allowed. Such a detection signal pattern is a detection signal pattern obtained even when a long skirt is worn without carrying baggage.

  On the other hand, when a passenger who does not have a baggage or has a baggage whose length dimension in the traveling direction is smaller than the dimension between the backs of the passengers, or a passenger who does not wear a long skirt, is measured by the light reflection sensors 18A and 18B. Two types of detection signal patterns are obtained for one passenger. The first type of detection signal pattern is a case where the foot on which the passenger has stepped is positioned on the detection beam of the light reflection type sensor 18A, 18B. The detection signal pattern at that time is a signal until the stepped-on foot kicks up, so that the detection signal pattern is substantially the same as that in FIG. 4 as shown by the solid line in FIG. The second type of detection signal pattern is a case where, for example, the passenger's right foot (left foot) crosses the detection beam of the light-reflective sensors 18A and 18B. The detection signal pattern at that time, as indicated by the arrows facing FIG. 5, is the detection signal for the right foot (left foot) that has previously crossed the detection beam of the light reflection type sensors 18A and 18B, and then the light reflection type sensor 18A. , 18B and a detection signal pattern of two peaks with a detection signal of the left foot (right foot) crossing the detection beam. By comparing the time Tb1 (To1, Ty1) between the two mountains with the reference movement time Tb1, it is possible to determine whether the person is a healthy person, an elderly person, or a young person, and the moving speed of the step 5 can be changed or maintained. .

  By the way, it takes about 1 second to completely switch the moving speed of the step 5 after detecting the passenger. Therefore, if a standard passenger travels 1 meter per second, the passenger is detected by the light-reflective sensors 18A and 18B, and then reaches the step 5 after 1 second. You can get on the step 5. For this purpose, it is desirable to install the light reflection sensors 18A and 18B, which are passenger detection units, at a position about 1 m away from the step-side tip of the getting-on / off floor 8A (8B) from the step side. Therefore, since the average dimension from the step-side tip of the landing floor 8A (8B) to the direction changing portion 7E of the moving handrail 7 is 0.8 m, the light reflecting sensors 18A and 18B are moved from the direction changing portion 7E of the moving handrail 7. Also, the detection beam is installed so as to be radiated so that the passenger M1 can be detected on the landing floor 8A (8B) on the opposite step side. However, since the speed change of the step 5 is changed slowly, even if it is a healthy person, even if it gets in the step 5 in the middle of the speed change, it will not be taken, and may be detected within 1 m. . Moreover, since the walking speed is slow for the elderly and the physically handicapped, for example, even if it is detected by the direction changing portion 7E of the moving handrail 7 that is about 0.8 m away from the step side tip of the getting-on / off floor 8A (8B), it is sufficient. The moving speed of the step 5 can be changed.

  In addition, by providing the two light reflecting sensors 18A and 18B on the right and left balustrade components, it is possible to detect all the passengers M1, M2 and M3 trying to get in from any position, and to completely detect the detection area 7 It can be on the boarding / alighting floor 8A (8B) on the side opposite to the step from the direction changing portion 7E. As a result, since the distance from the passenger detection position to the step 5 can be ensured, it is possible to avoid the passengers M1 to M3 getting on the step 5 whose moving speed is being changed.

  Further, the above explanation is an example of detecting the moving speed of one passenger M1 (M2 or M3) who tried to get into the escalator 1, but as shown by the two-dot chain line in FIG. When M3 gets in side by side, each passenger M2, M3 is set so that each light reflection type sensor 18A, 18B can detect it independently, so two passengers M2, M3 get in side by side In this case, the light reflection sensors 18A and 18B can detect the moving speeds of the passengers M2 and M3 independently. And when two passengers M2 and M3 get on side by side, a weak walking person may line up with a healthy person and a youth. In such a case, since the moving speed of the step 5 is supported by giving priority to the detection signal having a long moving time, the moving speed of the step 5 can be changed according to the weak walking person.

  By the way, in the present embodiment, the detection beams of the light reflection sensors 18A and 18B intersect at the center in the width direction before reaching the direction changing portion 7E of the moving handrail 7, and further extend from this intersection to about 30 cm ahead. It is what I did. The reason is that each detection beam always detects the left and right feet of the passenger. Specifically, referring to FIG. 1, the light reflection sensor 18A detects the left and right feet of the passenger M2 with the detection beam, and the light reflection sensor 18B detects the left and right feet of the passenger M3 with the detection beam. For the passenger M1 who is about to get in from the center, the light reflection sensors 18A and 18B respectively detect the left and right feet of the passenger M1 with each detection beam. However, if the radiation distances of the detection beams of the light reflection sensors 18A and 18B are up to the beam intersection, the light reflection sensors 18A and 18B have only one foot for the passenger M1 trying to get in from the center. It cannot be detected and the moving speed of the passenger cannot be detected. Therefore, the detection beams of the light reflection sensors 18A and 18B need to intersect once and extend about 30 cm away from the intersection.

  6 and 7 show a second embodiment of a passenger conveyor device according to the present invention. The same reference numerals as those in FIGS. 1 to 3 denote the same components, and thus detailed description thereof is omitted.

  In the first embodiment, the end cover 17 of the escalator 1 is provided with the light reflecting sensors 18A and 18B. As shown in FIGS. 6 and 7, both sides of the getting-on / off floors 8A and 8B are provided. When the guide fences 20A and 20B are installed, the light reflection sensors 18A and 18B may be installed using the guide fences 20A and 20B. In this case, it goes without saying that the passenger detection area is the same as that in the above embodiment.

  In addition, when walls exist on both sides of the escalator 1 instead of the guide rails 20A and 20B, the light reflection sensors 18A and 18B can be installed using the walls.

  Furthermore, as a modification of the second embodiment, a light reflecting sensor may be installed on each of the getting-on / off floors 8A (8B) in the vicinity of the end covers 17 on both the left and right sides to detect passengers. However, in this case, if the detection beam of the light reflection type sensor is radiated parallel to the floor surface, the passenger's feet may not be detected, so the range from 5 cm to 20 cm above the floor surface of the passenger floor 8A (8B). It is desirable to radiate the detection beam by tilting it upward so that the detection beam can be radiated.

  By the way, in the embodiment described above, the detection beams of the light reflection sensors 18A and 18B on both the left and right sides intersect further at the center in the width direction before reaching the direction changing portion 7E of the moving handrail 7 and further extend. It is installed. However, in a specific area or building, a half of the width direction of the step 5 is secured as a walking path, and the remaining half of the width direction of the step 5 is divided as a passenger boarding portion and a passenger conveyor device is used. Yes. In the passenger conveyor apparatus that performs such use, the detection beams of the left and right light reflecting sensors 18A and 18B intersect at the center in the width direction of the passenger boarding part before reaching the direction changing part 7E of the moving handrail 7. You may install as follows. In this way, by shifting the intersecting portion of the detection beams to the position side in the width direction, it is possible to accurately detect the moving speed of the passenger using half of the step 5 in the width direction as a walking path.

  In each of the above embodiments, the light reflection type sensor has been described as the passenger movement time detecting means. However, for example, a light blocking type sensor or other sensors may be used.

  Furthermore, in each said embodiment, although the escalator was demonstrated as a passenger conveyor apparatus, it cannot be overemphasized, and it cannot be overemphasized that it can apply also to the electric road which does not produce a level | step difference between adjacent treads.
