Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improved moving walkway that can safely and quickly transport passengers even on a relatively long journey.

[0002]

[Prior art]

 For example, in the case of a moving walkway installed at a place such as an airport, a normal moving walkway operating at 30 m / min has a problem that the speed is too slow and passengers take too long to move.

[0003] Therefore, a new type of moving walkway that moves gently when passengers get on and off and moves at high speed in the middle is desired, but as shown in Japanese Patent Laid-Open No. 2-75594, the following movement is performed. A sidewalk is proposed.

That is, FIG. 2 is a schematic view of a moving walkway composed of a plurality of endless circulation belts, and FIG. 3 is a partially enlarged view of FIG. 2, in which 2 is an extremely flexible endless sliding belt 20 as a set of eyes. It is an independent module that passes under the drive roller 25 and is always driven by the drive roller 31 at a constant speed. For example, the module 2 arranged near the entrance / exit is at a speed of 44 m / min / min. In the module 2'located at, the speed is 60m / min, 74m / min, 85m / min, 96m / min, 103m / min, and so on every time the passenger moves to the adjacent module 2, 2 '. It is configured to be accelerated or decelerated to. That is, the module 2 has a boarding / alighting belt, and the module 2'has an acceleration / deceleration belt. 15 is an extremely small small-diameter roller having a diameter of, for example, about 30 mm to 70 mm, which is arranged at both ends of each module 2 or 2 ', and the gap between the opposing small-diameter rollers 15 is quite small like children's shoes. It is suppressed to a size of about 20 mm to 40 mm, which is smaller than that of shoes.

Reference numeral 10 denotes a T-shaped carrier plate whose upper surface is arranged in a position lower than the upper surface of the endless sliding belt 20 in the gap between each pair of adjacent modules 2 or 2 ′, and the circulation speed of the endless sliding belt is It is described that it may be omitted if it is fast. Reference numeral 26 is a sliding plate that supports and guides the upper track of the endless sliding belt 20. 27 is a long main circulation belt that forms the center of the fastest moving walkway in the vicinity of the high speed module 2.

[0006]

[Problems to be solved by the device]

 However, in the case of a variable-speed moving walkway in which multiple rubber belts with different speeds are continuously installed and transport at low speed at the entrance and exit and high speed at the middle part, passengers on the high-speed belt block the front. As a result, passengers will be crowded in the deceleration area as they walk more and more, and as a result, passengers may get crowded and fall accidents may occur when the passengers shift to the low-speed belt.

The present invention has been made in view of the above points, and an object of the present invention is to provide a variable speed moving walkway that smoothly transports passengers according to the degree of congestion of passengers.

[0008]

[Means for Solving the Problems]

 According to the present invention, several independent boarding / alighting belts and acceleration / deceleration belts are sequentially installed adjacent to each other in the operation direction before and after the main circulation belt, these circulation belts are operated in the same direction, and the circulation belt on the entrance side is advanced. The traveling speed is gradually increased as it reaches the direction, and on the other hand, the traveling speed is gradually reduced on the exit side, and passenger congestion on the main circulation belt is detected on a moving sidewalk where the main circulation belt has the highest operation speed. When the detection means detects a congestion state above a predetermined level, the operation speed of the main circulation belt and the acceleration / deceleration belt is reduced.

[0009]

[Action]

 With the above configuration, even if passengers on the main circulation belt are crowded, the passengers can be transported smoothly.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a diagram showing an embodiment of the present invention, FIG. 4 is a view taken along the line AA in FIG. 1, and FIG. 5 is a diagram showing an example of the configuration of a detection device for detecting the degree of congestion of passengers according to the present invention. It is a figure, and the thing of the same code as Drawing 2 and Drawing 3 shows the same thing.

Reference numeral 40 denotes a balustrade installed upright on both side ends of the main circulation belt 27, and extends upright on a part of both side ends of the endless sliding belt 20 adjacent to the main circulation belt 27. 41 is a handrail movably provided so as to surround the parapet 40, 50 is a balustrade installed upright at both ends of the endless sliding belt 20 adjacent to the comb plate 60 at the exit of the moving walkway, and 51 is also the same. A handrail movably provided so as to surround the balustrade 50, and 70 is a molding that covers the lower portions of the balustrades 40 and 50.

Reference numeral 80 denotes a photoelectric device provided in the molding 70, which includes a projector 81, a light receiver 82, and a signal processing device 85 with the main circulation belt 27 sandwiched between them. The main circulation belt 27 causes endless sliding in a deceleration area. It is a device for detecting the degree of congestion of passengers transferring to the belt 20.

Reference numeral 83 is a well-known counter that counts the number of pulses 82a output from the light receiver 82, and outputs a signal 83a corresponding to the number of pulses within a predetermined time set in advance. Reference numeral 84 is a well-known comparator, which compares preset reference signals 84b and 83a, and outputs an output signal 84a when 83a> 84b.

That is, the degree of congestion of passengers who are about to enter the deceleration area is detected, and when the congestion of the passengers exceeds the predetermined congestion, the deceleration command 84a for reducing the speeds of the main circulation belt 27 and the acceleration / deceleration belt is output. To do.

Such a congestion degree detection device may be, for example, a device in which an image pickup tube is arranged on a ceiling, signal processing is performed on an image obtained from the image pickup tube, and the congestion degree of passengers is detected. In addition, various devices can be considered in addition to the above, and the device is not limited to the embodiment.

Even if the speeds of the main circulation belt 27 and the acceleration / deceleration belt are decreased, the transportation force of the moving sidewalk itself does not change at all by keeping the speed of the boarding / alighting belt constant.

[0017]

[Effect of device]

 As described above, according to the present invention, even if passengers come into close contact with each other on a high-speed belt, the speed of the belt is reduced by detecting it, so that a situation in which passengers are more crowded in the deceleration area is avoided in advance. be able to. Moreover, even if the belt speed is reduced, the moving capacity of the moving walkway itself can be maintained high.
