JPH09142765A - Moving sidewalk having accelerating and decelerating zones - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a moving sidewalk with no gaps and no height difference in the tread surface thereof, composed of a belt having one end guided by an outer guide rail, and the other end guided by an inner guide rail, and a bracket having bend rollers, and sprockets for driving the belt. SOLUTION: A unit A is composed of a belt 1, a bracket 2, a coupling shaft 3, and bend rollers 22, 23, 24, and a unit B is provided in the rear of the former as viewed in the advancing direction thereof. When the unit A is moved at a speed V in a direction X, the belt 1 is slid at a relative speed given by Vtanθ/sinθ in the direction X since an inner guide rail 5 is inclined at an angle θin an accelerating zone. Accordingly, the rear unit B is moved in the direction X at a speed V-Vtanθ/sinθ, and accordingly, the unit A moving ahead is accelerated by Vtanθ/sinθ in comparison with the unit B. In the case of deceleration the above-mentioned relation is reversed.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a moving walkway for carrying personnel, and more particularly to a moving walkway having acceleration and deceleration zones.

[0002]

2. Description of the Related Art A moving walkway is known as a short-distance transportation system for carrying personnel in facilities such as station premises, airport facilities and tourist resorts.

By the way, many moving walkways have a constant transfer speed from the entrance to the exit, but in recent years, the entrance has been slowed down from the viewpoint of passenger safety, and gradually accelerated to a high speed in the middle part. At the exit, the following moving sidewalk is disclosed that slows down again while decelerating.

The technique disclosed in Japanese Unexamined Patent Publication No. 50-6081 discloses that "an auxiliary tread having a crosspiece that meshes with the crosspiece of the main tread is provided between the main treads in the high speed zone. , The auxiliary tread rises between the main treads to form a high speed range.

Further, the technique disclosed in Japanese Patent Laid-Open No. 55-15395 is a technique of "providing a plurality of platforms and determining the speed by the overlapping amount of the platforms".

[0006]

However, the technique disclosed in the above publication has the following problems.

In the technique disclosed in Japanese Patent Application Laid-Open No. 50-6081, since the crosspiece of the main tread plate and the crosspiece of the auxiliary tread plate overlap with each other in a comb-teeth state, a gap is generated on the tread surface and foreign matter is easily caught.

In the technique disclosed in Japanese Patent Laid-Open No. 55-15395, steps are formed because the platforms are overlapped with each other, and the passengers' legs are easily caught when they expand or contract, and they fall easily.

An object of the present invention is to provide a moving walkway having acceleration and deceleration zones with no gaps on the tread surface and no steps.

Means for Solving the Problems The above-mentioned problems are solved in that the outer guide rail is formed in an annular shape over the moving section, and the outer guide rail is formed in an annular shape inside the outer guide rail. An inner guide rail arranged in a changed manner, a belt whose one end is guided by the outer guide rail, and the other end of which is guided by the inner guide rail, and a slide of which the one end is connected to one end of the belt and the other end. A bracket having a vent roller slidably supporting the other end of the belt in the long hole,
The solution is a moving walkway with acceleration and deceleration zones consisting of a drive sprocket driving the belt and a driven sprocket.

One end of the belt is moved along the outer guide rail, and the other end is moved along the inner guide rail whose position changes, thereby changing the protrusion angle of the belt. In the acceleration zone, the speed is increased by the positive inclination angle of the inner guide rail, and through the high speed zone, the speed is decreased by the negative inclination angle of the inner guide rail in the deceleration zone to the exit.

Is a belt, 2 is a bracket, and the outer guide rail 4
Is formed in an annular shape, and the inner guide rail 5 is also formed in an annular shape inside thereof.

The inner guide rail 5 is formed at a predetermined distance from the outer guide rail 4 in the low speed zone a which is the entrance, and the inclination angle Θ shown in FIG. 1 is zero.

In the acceleration zone b, the inclination angle Θ is formed such that Θ ≠ 0. In the high speed zone c, the inner guide rail 5
Are formed at intervals closer to the outer guide rail 4 than the low speed zone a, and the inclination angle Θ of the inner guide rail 5 is Θ = 0.

In the deceleration zone d, the inclination angle Θ of the inner guide rail 5 forms a negative angle −θ in the opposite direction to the acceleration zone b, and in the low speed zone e at the exit, the low speed zone a at the entrance. Similarly, the inclination angle Θ is formed to be zero.

The principle of acceleration and deceleration of the present invention having the above-mentioned structure will be described below with reference to FIG.

When the unit consisting of the belt 1, the bracket 2, the connecting shaft 3, and the bend rollers 22, 23, 24 is a unit A and the rear side in the traveling direction is a unit B, the unit A is guided to the outer guide rail 4 and the inner guide rail 5. When the vehicle is moved in the X direction at the speed V, the inner guide rail 5 is formed to be inclined by the angle Θ in the acceleration zone, and therefore the guide shaft 12 guided by the inner guide rail 5 is formed.
Moves in the Y direction at a speed of Vtan Θ, and accordingly, the belt 1 slides in the X direction at a relative speed of Vtan Θ / sin θ (θ ·· the bending angle of the belt 1). As a result, the rear unit B moves in the X direction at the speed V-Vtan Θ.
It will move at / sin θ.

That is, the preceding unit A is accelerated by Vtanθ / sinθ more than the succeeding unit B. The opposite is true for deceleration.

A plurality of engaging portions 8b, 8c are formed on the outer periphery of the drive wheel 8, the connecting shaft 3 of the belt 1 engages with the engaging portion 8b, and the shaft of the bend roller 22 engages with the engaging portion 8c. It is a structure that engages and gives a moving force to the belt 1.

[0032]

According to the present invention, the structure in which the angle of inclination of the inner guide rail is changed and the amount of protrusion of the belt is changed allows formation of low-speed, medium-speed, and high-speed zones for safe entry and exit. It is simple and inexpensive, and has the advantage that it requires less power because it is lightweight.

Further, since the belt is used, there is no gap on the tread surface, so that no foreign matter is caught, and the bend roller and the small comb teeth are used, so that the tread surface can be kept flat and an accident such as a fall due to a tripping can be prevented. There is no.
