Description

  The present invention relates to a passenger conveyor such as an elevator or a moving sidewalk, and more particularly to a passenger conveyor in which a sensor for detecting the presence or absence of a passenger entering a boarding gate is disposed in a skirt portion.

  2. Description of the Related Art Conventionally, as a passenger conveyor installed in a building or the like, an automatic operation type passenger conveyor is known in which automatic detection is performed by detecting the presence or absence of a passenger with a sensor. In this passenger conveyor, a sensor is provided on photoelectric poles (posts) installed at entrances and exits, and when no passenger is detected by this sensor, the operation is stopped and a passenger is detected by the sensor. It is configured to operate at the rated speed.

  This type of passenger conveyor requires the installation of photoelectric poles at the entrance and exit, so the installation space must be secured, and it cannot be handled in some places, and there are design problems. Thus, a so-called poleless type automatic driving system passenger conveyor is known in which a photoelectric pole is eliminated by incorporating a passenger detection sensor in the front skirt of the passenger conveyor (see, for example, Patent Document 1 below). .

Japanese Patent Laid-Open No. 10-182050

  However, in recent years, in spite of a demand for narrowing the width direction of the main body, in the poleless type automatic operation type passenger conveyor as described above, a pair of skirt portions provided on both sides of the step are parapets. Since an inner skirt portion that protrudes further inward in the width direction is formed and a sensor for passenger detection is housed in the inner skirt portion, there is a problem that it is difficult to narrow the passenger conveyor.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a passenger conveyor that can easily narrow the width direction of the main body even if a passenger detection sensor is provided on the front skirt of the passenger conveyor.

  A passenger conveyor according to the present invention includes a step, a pair of skirt portions provided on both sides of the step, a balustrade erected from the pair of skirt portions, and a moving handrail that moves along the outer periphery of the balustrade A front skirt cover provided at a front end portion of the balustrade and provided with a handrail hole through which the moving handrail enters and exits the pair of skirt portions, and a primary member that detects passengers that are disposed in the skirt portion and pass through a boarding board. The front skirt cover is provided with a protrusion that protrudes toward the boarding board below the handrail hole, and the central axis of the detection range of the primary sensor is defined with respect to the passenger entry direction. The primary sensor is housed in the protrusion so as to be directed inward by a predetermined angle and upward by a predetermined angle with respect to the horizontal direction.

  In the passenger conveyor according to the present invention, the body width direction can be narrowed by the above configuration even if a passenger detection sensor is provided in the front skirt portion of the passenger conveyor.

It is a lineblock diagram showing a passenger conveyor concerning one embodiment of the present invention. It is a side view which fractures | ruptures and shows a part of balustrade near the entrance / exit of the said passenger conveyor. It is a front view of the balustrade shown in FIG. It is a top view which shows the entrance / exit vicinity of the said passenger conveyor. It is a side view which shows the entrance / exit vicinity of the said passenger conveyor.

  A first embodiment of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a passenger conveyor 10 according to an embodiment of the present invention is an escalator installed to be inclined across the upper and lower floors of a building, for example, and a large number of steps 12 are placed on the upper and lower floor boarding boards. The passenger boarded on the step 12 is transported between the upper floor and the lower floor by circulating and moving between the entrances 11a and 13a provided on the rails 11 and 13. A number of steps 12 are connected by an endless conveyor chain 14 and are arranged in a main frame 16 called a truss installed under the floor of the building.

  A pair of balustrades 18 are erected on both sides of the upper portion of the main frame 16 along the moving direction of the step 12, and a belt-like moving handrail 20 is attached to the outer periphery of the balustrade 18. The moving handrail 20 circulates in synchronization with the step 12.

  A skirt portion 22 that covers the connecting portion between the main frame 16 and the balustrade 18 is provided in the lower part of the balustrade 18 from the entrance 11 on the upper floor to the entrance 13 on the lower floor. A front skirt cover 50 is provided on both sides of the skirt portion 22 in the longitudinal direction, that is, on the tip of the balustrade 18, and closes the tip of the skirt 22.

  As shown in FIGS. 1 to 3, the front skirt cover 50 includes a handrail hole 24 through which the moving handrail 20 enters and exits, and a protrusion 52 that protrudes toward the boarding / removal plates 11 and 13 below the handrail hole 24.

  During the ascending operation of the passenger conveyor 10, the moving handrail 20 appears from the inside of the skirt portion 22 through the lower floor handrail hole 24 serving as the entrance, and from the upper floor handrail hole 24 serving as the exit gate to the skirt portion. Enter 22. Further, during the descending operation of the passenger conveyor 10, the moving handrail 20 appears from the inside of the skirt portion 22 through the upper floor side handrail hole 24 serving as the entrance, and from the lower floor side handrail hole 24 serving as the exit gate. It goes into the skirt part 22. And in each driving | running | working of a raise and descent | fall, when a moving handrail 20 drive | works the upper end side of the balustrade 18, it uses for a user to hold | grip with a hand.

  A cylindrical inlet member 26 that encloses the moving handrail 20 that circulates and moves is inserted into the handrail hole 24, and is supported so as to be movable along the moving direction of the moving handrail 20. The inlet member 26 is made of rubber and has flexibility.

  As shown in FIG. 2, the inlet member 26 is inserted into a handrail hole 24 provided in the front skirt cover 50, and one end side is located in the skirt portion 22 and the other end is located outside the skirt portion 22. . An operation plate 28 is fixed to one end side of the inlet member 26 positioned in the skirt portion 22, and a convex portion 29 is provided on the operation plate 28. An inlet safety switch 30 is provided at a position facing the convex portion 29 in the skirt portion 22.

  When the inlet member 26 is drawn into the skirt portion 22 by a predetermined distance L from the initial position P0 and moves to the detection position P1, the convex portion 29 presses the inlet safety switch 30. As a result, the inlet safety switch 30 is actuated to detect that foreign matter has been drawn into the handrail hole 24.

Around the handrail hole 24, an inlet guard portion 54 that protrudes from the front skirt cover 50 toward the passenger board 11, 13 is integrally formed with the front skirt cover 50, and the inlet that protrudes from the front skirt cover 50 is formed. The outer periphery of the member 26 is covered. Thus, by covering the outer periphery of the inlet member 26 with the inlet guard portion 54, it is possible to prevent the passenger's baggage or feet from accidentally hitting the inlet member 26 and causing the inlet safety switch 30 to malfunction.

  The protrusion 52 is formed to protrude from the end face of the front skirt cover 50 toward the boarding / removal plates 11 and 13, that is, in a direction away from the end face of the front skirt cover 50 along the moving direction of the steps 12. The inside of the protrusion 52 forms a storage space S in which the passenger detection device 60 is stored.

  The position P2 of the end surface 52a of the projecting portion 52 along the moving direction of the step 12 is in a direction further away from the end surface of the front skirt cover 50 than the detection position P1 of the inlet member 26 where the inlet safety switch 30 is operated by the convex portion 29. It protrudes toward the boarding / removal plates 11 and 13.

  A pair of passenger detection devices 60 are arranged on each of the upper and lower floors, and are closer to the step 12 than the passenger detection sensor (primary sensor) 62 that detects a passenger who has entered the entrances 11a and 13 and the passenger detection sensor 62. And a secondary sensor 64 that detects a passenger just before entering the step 12 after detecting the passenger passing on the boarding board 11, 13 by the passenger detection sensor 62.

  The passenger detection sensor 62 is, for example, a reflected light detection type passenger detection device, and includes a light receiving element 62a and a light projecting element 62b each having a substantially cylindrical shape, and the light receiving element 62a is located above the light projecting element 62b. Both elements 62a and 62b are arranged vertically so as to be positioned.

  Both the light receiving element 62a and the light projecting element 62b are attached to a fixture 63 fixed to the main frame 16, and the light projecting direction and the light receiving direction are directed inward by a predetermined angle with respect to the passenger entering direction, And it is positioned and fixed upward by a predetermined angle with respect to the horizontal direction.

  As a result, the pair of passenger detection sensors 62 and 62 disposed in the storage space S of the pair of left and right balustrades 18 detect each other when looking down in the vertical direction from above the entrance / exit as shown in FIG. The center axis CL, CL of the range intersects on the boarding board 11, 13, and the boarding board 11 is as the center axis CL, CL of the detection range moves away from the step 12 when viewed in the horizontal direction as shown in FIG. 5. , 13 is higher.

  The passenger detection sensor 62 arranged as described above emits light from the light projecting element 62b, and the light projected toward the detection target (that is, the passenger) is reflected by the detection target. By detecting the reflected light with the light receiving element 62a, the presence or absence of a passenger can be detected.

  In the present embodiment, in the passenger detection sensor 62, the light receiving element 62a is disposed above the light projecting element 62b as described above, but there is no problem even if the light receiving element 62a is disposed below the light projecting element 62b. It can be detected.

  As the secondary sensor 64, for example, a transmissive photoelectric sensor having a structure in which a light projector 64a and a light receiver 64b are arranged to face each other is used. The secondary sensor 64 uses the fact that the light emitted from the projector 64a and directed to the light receiver 64b is blocked by the passenger passing between the projector 64a and the light receiver 64b. Passengers who pass through and board the step 12 are detected.

  The passenger conveyor 10 according to the present embodiment is provided with a drive control device that controls automatic operation. While no passengers entering the entrance / exit are detected by the passenger detection sensor 62, operation is stopped or passengers wait by low-speed operation. In this state, power consumption is reduced. Then, when a passenger is detected by at least one of the passenger detection sensors 62, operation at a normal speed is started. Thereafter, when a passenger immediately before entering the step 12 is detected by the secondary sensor 64, a timer inside the drive control device starts counting, and the passenger is moved from one of the entrances 11a, 13a to the other entrance 13a, 11a. When a predetermined time T1 obtained by adding a predetermined margin time to the time required for transporting, the operation at the normal speed is stopped and the passenger standby state is restored.

  As described above, in the passenger conveyor 10 according to the present embodiment, the front skirt cover 50 is formed with the protruding portion 52 that protrudes toward the passenger board 11 and 13 and accommodates the passenger detection device 60. Even if the detection device 60 is provided, the width direction of the passenger conveyor 10 can be narrowed.

  Moreover, in the passenger conveyor 10 in this embodiment, since the protrusion part 52 protrudes from the end surface of the front skirt cover 50, the number of parts can be reduced and manufacturing cost can be suppressed. In addition, the protrusion 52 is formed below the handrail hole 24 into which the movable handrail 20 and the inlet member 26 are inserted, and is difficult to be noticed by passengers. This is because the protrusion 52 is integrated with the skirt portion 22. As a result, the passenger conveyor's aesthetics are not impaired.

  In addition, the passenger detection sensor 62 is arranged so that the center axis of the detection range of the passenger detection sensor 62 is directed inward by a predetermined angle with respect to the passenger entry direction and upward by a predetermined angle with respect to the horizontal direction. Therefore, it is possible to suppress erroneous detection outside the detection target area while ensuring that the passenger can be reliably detected in the area that is desired to be set as the detection target area by the passenger detection sensor 62.

  Furthermore, by replacing the front skirt cover with the front skirt cover 50 formed with the protrusions 52 shown in the present embodiment for the existing passenger conveyor provided with photoelectric poles for passenger detection near the entrance / exit, It can easily be a poleless type automatic driving system passenger conveyor.

  Further, the position P2 of the end surface 52a of the protrusion 52 protrudes toward the boarding plates 11 and 13 in a direction further away from the end surface of the front skirt cover 50 than the detection position P1 of the inlet member 26. Even if a baggage or foot of a vehicle or passenger accidentally enters the lower side of the tip of the balustrade 18, the inlet member 26 contacts the end surface 52a of the protruding portion 52 before moving to the detection position P1. For this reason, the inlet safety switch 30 does not operate and malfunction can be prevented.
