Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a variable-speed passenger conveyor in which the moving speed of a pallet changes, and more particularly to a variable-speed passenger conveyor characterized by an auxiliary pallet for interpolating between pallets in a high-speed zone.

[0002]

2. Description of the Related Art Recently, many passenger conveyors for transporting passengers without walking have been installed in airports, train stations, tourist facilities, and the like.

[0003] Conventional passenger conveyors generally have a constant speed from the entrance to the exit, and the entrance and exit must have a speed of about 40 m / min or less in order to ensure passenger safety. At the aforementioned speed, the speed is constant from the entrance to the exit.

[0004] However, long-distance passenger conveyors installed as transfer access to city transportation are strongly demanded to increase the transport speed.

[0005] Conventionally, a variable-speed passenger conveyor for changing the moving speed of a pallet between an entrance and an exit is known from the following patent publications.

A "moving sidewalk having an acceleration / deceleration mechanism" disclosed in Japanese Patent Laid-Open Publication No. Sho 50-6081 (hereinafter referred to as "prior art 1") is obtained by changing an auxiliary tread connecting a main tread in the height direction. The speed of the tread is changed by changing the connection length.

[0007] Japanese Unexamined Patent Publication No. Sho 52-64782 (hereinafter referred to as "prior art 2") discloses a "running sidewalk for acceleration and deceleration" in which treads are overlapped with each other, and the amount of overlap is controlled. This changes the speed of the tread.

[0008]

However, in the above-mentioned prior art 1, since it is basically assumed that the auxiliary tread fits within the width of the main tread, the maximum change in the speed of the tread physically is: The upper limit is twice, and in practice, it is limited to 1.8 to 1.9 times due to design restrictions, and there is a problem that the speed-up is insufficient.

In the above-mentioned prior art 2, it is possible in principle to increase the speed change. However, the interference between the treads causes abrasion of the contact portion and noise, and the floor surface has irregularities. Is dangerous when traveling on treads,
Further, it is difficult to secure engagement with the fixed comb teeth at the entrance and exit, which is dangerous particularly at the exit.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to greatly increase the speed.

[0011]

A first means for solving the above-mentioned problems is to provide a variable-speed passenger conveyor for transferring passengers by changing the transfer speed of a pallet from an entrance to an exit. A traveling rail having a section including the area up to the exit is formed in a loop, a plurality of pallet bodies traveling along the traveling rail, and a loop-shaped track different from the traveling rail of the pallet body. An auxiliary guide rail, an auxiliary pallet which runs along the auxiliary guide rail and is normally stored in the lower portion of the pallet body and drawn out between the pallet bodies in the high-speed zone, A comb-teeth plate drawn out between the pallet body and the auxiliary pallet and interpolating between the pallet body and the auxiliary pallet. It is the type passenger conveyor.

A second means for solving the above-mentioned problem is that the comb tooth tread comprises a roller for moving a guide on the side of the pallet main body, and a connecting mechanism for connecting the pallet main body or the auxiliary pallet. The variable-speed passenger conveyor according to the first means.

Further, a third means for solving the above-mentioned problem is characterized in that the auxiliary guide rail is shifted upward in order to make the tread surface of the auxiliary pallet the same as the tread surface of the pallet body in the high-speed zone. The variable-speed passenger conveyor according to the first or second means.

According to the above-mentioned means, when the pallet body is located in the high-speed zone, first, the auxiliary pallet is drawn out from the pallet body to the preceding pallet body, and then the comb tooth tread is removed from the pallet body. In the high-speed zone, the pallet body, the auxiliary pallet, and the comb tread are the same length, and the length per unit time is longer than the length of the pallet body alone at the entrance and exit. It will be much faster.

Further, the auxiliary pallet and the comb-tooth plate are pulled out from the pallet body by a connecting mechanism provided on the comb-tooth plate.

Further, the tread surface of the auxiliary pallet in the high-speed zone is formed flush with the tread surface of the pallet body due to a change in the height of the auxiliary guide rail for guiding the traveling of the auxiliary pallet, so that passengers do not feel uncomfortable.
