Description

  The present invention includes an escalator in which a step board moves in a staircase, an electric road that does not generate a step between adjacent treads, and an escalator in which a section in which a step does not occur between adjacent treads and a section in which a step board moves in a staircase are mixed The present invention relates to a passenger conveyor device, and more particularly, to a passenger conveyor device that changes a moving speed of a tread according to a walking speed (moving time) of a passenger.

  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-mentioned object, the present invention provides detection means on both sides in the width direction for detecting the time from stepping on the foot of a passenger who is going to get on the tread board from the getting-on / off floor to the kick-up, and the detection means detects these. A control device is provided for changing the moving speed of the tread board from the moving time when the passenger's foot is depressed based on the time and the reference time, and the detection means on both sides can be detected independently.

  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. And, since the movement time from stepping on the passenger's foot to kicking up is measured by an on-off signal of each passenger movement time detection means of an independent circuit configuration, when the passenger gets in line, Since the moving speed of the tread can be set based on the longer travel time detected, the moving speed of the tread can be set giving priority to weak walkers, and there is a predetermined interval in the passenger moving direction as in the past. This eliminates the need for two detectors.

  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's moving speed can be detected with a sufficient precision, and especially the passenger conveyor which can detect the moving time of a weak walking person with a sufficient precision and can set the optimal tread board moving speed can be obtained.

  Hereinafter, a first embodiment of a passenger conveyor according to the present invention will be described based on an 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 upper side of the skirt guard 14, 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. It is comprised by balustrade components, such as 17.

  The light reflection type which is a passenger movement time detecting means for emitting a detection signal by irradiating a detection beam as a detection medium to the right and left end cover 17 which is a balustrade component of the escalator 1 configured as described above. Sensors 18A and 18B are respectively attached. The light reflection sensors 18A and 18B are installed so as to irradiate the detection beam so as to be substantially parallel to the floor surface of the passenger floor 8A (8B), and all the passing passengers M1, M2, and M3 are passed. In order to be able to detect, it is installed to irradiate the detection beam in a direction crossing the passenger traveling direction, and the light reflection sensors 18A and 18B are configured by independent circuits, and each can detect a passenger alone. I am doing so.

  Detection signals from the light reflection sensors 18A and 18B are 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 the calculation in the control device 19, the detection signal with the longer passenger movement time (the detection time is longer) is prioritized, and based on this detection signal, the drive device 12 is instructed to change the speed of the step 5. I have to.

  As described above, since the light reflection sensors 18A and 18B are provided on the end cover 17, the detection beams from the light reflection sensors 18A and 18B are now placed on the legs of the passengers M1 and M2 who are trying to get on the escalator 1 side by side. Is reflected, the reflected light returns to the light reflection sensors 18A and 18B, and a detection signal is output. As shown in FIG. 4, the ON time of the detection signal is compared with the reference movement time Tb as shown in FIG. 4, and if it is substantially the same as the reference movement time Tb, it is determined that the person is a normal healthy person. 19 instructs the driving device 12 to drive the step 5 at the standard speed. Compared to the reference movement time Tb, if the movement time To is longer than the reference movement time Tb, it is determined that the elderly person or a physically handicapped weak person is weak, and the control device 19 causes the drive device 12 to move the step 5 at a low speed. Command to drive. Conversely, if the movement time Ty is shorter than the reference movement time Tb compared to the reference movement time Tb, it is determined that the person is a young man, and the control device 19 drives the drive device 12 at the standard speed. Or it is instructed to operate at a higher speed than the standard speed. Although one detection signal of the two light reflection sensors 18A and 18B is displayed in FIG. 4, the other detection signal is also displayed in substantially the same manner. However, it is rare for the two passengers M1 and M2 to have exactly the same travel time, and naturally there is a difference in travel time. At that time, the control device 19 gives a speed command to the drive device 12 in preference to the longer travel time detected.

  Next, when the passenger M1 or the passenger M2 gets in alone, the light reflection sensor 18A or the light reflection sensor 18B detects the movement time as shown in FIG. Can be supported.

  Furthermore, when the passenger M3 gets in from the center, the two traveling times are output because the detection beams of the two light reflection sensors 18A and 18B are respectively traversed. If the two travel times are exactly the same, the travel speed of the step 5 is indicated by either detection signal. If there is a difference between the two travel times, the detection signal with the longer travel time is given priority. Since the movement speed of the step 5 is instructed, there is no problem for the weak walking person.

  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 sensor 18 is 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 swing of the passenger's hand. It is possible to detect the moving speed of the passenger with high accuracy.

  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 position of the light reflection sensors 18A and 18B, particularly the installation height, is set to a position where the feet of the passenger are irradiated. 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 when the light-reflective sensor 18 is installed at a height of 5 cm or less, the step of the passenger There is a possibility that the side foot 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 carrying baggage is measured by the light reflection type sensor 18A (18B), and if the on-time of the detection signal is substantially the same as the reference movement time Tb, it is determined that the passenger is a normal healthy person. The drive unit 12 is instructed to drive the step 5 at the standard speed. Compared with the reference movement time Tb, if the movement time To is longer than the reference movement time Tb, 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 Ty is shorter than the reference movement time Tb compared to the reference movement time Tb, it is determined that the person is a young person, and the control device 19 sets the step 5 to the drive device 12 at the standard speed or the standard speed. 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, a passenger with baggage that does not have baggage or whose length in the traveling direction is smaller than the dimension between passengers' backs, and who does not wear a long skirt is measured by the light reflection sensor 18A (18B). Then, two types of detection signal patterns are obtained for one passenger. The first type of detection signal pattern is a case where the foot that the passenger steps on 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 reflection type sensor 18A (18B). The detection signal pattern at that time is, as shown by a chain line in FIG. 5, a detection signal Tb1 (To1, Ty1) of the right foot (left foot) that has previously crossed the detection beam of the light reflection sensor 18A (18B), and then It becomes a detection signal pattern of two peaks with the detection signal Tb2 (To2, Ty2) of the left foot (right foot) crossing the detection beam of the light reflection type sensor 18A (18B). Then, by comparing the time Tb (To, Ty) between the two mountains with the reference movement time Tb, 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. In addition, the detection beam is installed 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.

  By the way, in the said embodiment, although it is the structure in which a wall and a guidance fence do not exist around the escalator 1, as shown in 2nd Embodiment by this invention shown in FIG. 6, one side of the escalator 1, especially When the wall 20 is present on one side of the boarding / alighting floor 8A (8B), the light reflection type sensor 18A is provided on the wall 20 and the light reflection type sensor 18B is fixed on the floor or the boarding / alighting floor 8A (8B). You may provide in SB. In this case, the detection area of the passenger is completely on the boarding / alighting floor 8A (8B) on the side opposite to the step from the direction changing portion 7E of the moving handrail 7 and the detection beam is emitted at a position close to the direction changing portion 7E of the moving handrail 7 By irradiating so as to be orthogonal to the passenger traveling direction, only passengers using the escalator 1 can be detected.

  In addition, when there are walls 20 and guide fences on both sides of the escalator 1, particularly on both sides of the getting-on / off floor 8A (8B), the light reflection type sensor 18 is installed using either the walls 20 or the guide fences on both sides. can do.

  7 and 8 show a third embodiment of a passenger conveyor according to the present invention. In each of the above embodiments, the light reflection sensors 18A and 18B are installed on the balustrade component of the escalator 1, or are installed on the wall 20 or the support bracket SB. However, as shown in FIGS. 7 and 8, the light reflection sensors 21A and 21B are installed on the getting-on / off floor 8A (8B) on the opposite side of the direction changing portion 7E of the moving handrail 7 to detect passengers. You may make it do. However, in this case, if the detection beams of the light-reflective sensors 21A and 21B are irradiated in parallel to the floor surface, the passenger's feet may not be detected, and therefore, 5 cm to 20 cm above the floor surface of the passenger floor 8A (8B). It is desirable to irradiate the detection beam by tilting it upward so that the detection beam can be irradiated within the range.

  Further, as shown by the two-dot chain line in FIG. 8, the boarding / exiting is performed on the floor surface of the boarding / exiting floor 8A (8B) or the floors of the upper floor 2 and the lower floor 3 where the light reflecting sensors 21A and 21B are installed. Supports 22A and 22B having a height of 5 cm to 20 cm above the floor surface of the floor 8A (8B) are erected, and the light reflection sensors 21A and 21B are fixed to the support columns so that the detection beam is substantially parallel to the floor surface. There is no problem even if it is irradiated.

  By the way, in each said embodiment, although the light reflection type sensor was demonstrated as a passenger movement time detection means, for example, a light interruption type sensor and another sensor may be sufficient.

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