DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving sidewalk, and more particularly, to a walking speed (60 to 70 m / m) from a low speed at the time of riding.
in) It relates to a moving sidewalk that can be accelerated to a degree or vice versa.

[0002]

2. Description of the Related Art A moving sidewalk currently in practical use has a speed of 30 to 40 m / min and a human walking speed (60 to 70 m / min).
Slower, accelerated sidewalks are desired. Various methods have been studied to meet this demand, but none has been completely put into practical use yet. FIG. 15 shows an example of a moving sidewalk developed by ACB of France, which is called TRAX SYSTEM ("NIKKEI MECHANICAL").
1983.1.31 page 20). Referring to FIG. 15, the supporting unit a is a rotatable pallet (stepping plate) on which a person rides, and receives a load by a pair of rollers c in contact with two central rails b. On both sides of the support unit a, there are spline-slidable parts, on which a roller e running along a guide d and a sprocket g having a chain f are attached. Since the chain f forms a loop of the same length between the adjacent support units a, the support unit a moves closer or farther when the roller interval is changed by the guide d. As a result, the overlapping length of the pallets fixed to the support unit a is increased or decreased. With this structure, the speed of getting on and off is the slowest at 3 km / h,
The center part (highest speed) between the acceleration and deceleration sections of about 10 m is 1
It changes to 2 km / h. However, although this system was successful as a test machine, its mechanism was very complicated and disadvantageous in terms of cost, and it has not yet been fully commercialized without solving the noise generation problem.

[0003]

In the middle of the sidewalk, a person walks at a speed that is slow at the initial stage of riding on the sidewalk, and is slowed down when getting off the sidewalk. It is an object of the present invention to provide a moving walkway that is simple in structure and can be provided at low cost, and that operates securely and safely.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given with reference to FIGS. FIG. 1 shows the overall configuration of a moving walkway according to the present invention. 1 is a low-speed belt conveyor disposed adjacent to the entrance / exit, 2 is a medium-speed belt conveyor disposed following the low-speed belt conveyor 1, and 3 is an intermediate portion disposed following the medium-speed belt conveyor 2. Is a high speed belt conveyor. Each belt conveyor has a drive pulley.
1b and the bend pulley 1b are stretched endlessly. In the vicinity of the exit, the high-speed belt conveyor 3, the medium-speed belt conveyor 2, and the low-speed belt conveyor 1 are arranged in reverse. On the belts of the belt conveyors 1, 2, 3 are provided a series of telescoping pallets 4 which move in contact with the belts only by friction with the belt conveyors. The telescopic pallet 4 is guided on both sides by guide rails 5 and guide rollers 6 (FIG. 10). Reference numeral 7 denotes a hexagonal guide wheel provided at the reversing portion of the telescopic pallet 4, and reference numeral 8 denotes a support roller for preventing it from hanging down. Reference numeral 9 denotes a handrail divided according to the speed of the belt conveyors 1, 2, and 3.

The details of the telescopic pallet 4 will be described below.
The telescopic pallet 4 is composed of two kinds of combinations of a pallet A4a and a pallet B4b (FIG. 6). The pallet A4a has a plurality of elongated grooves 10 which are parallel to each other and open upward, and
4b is a plurality of long comb teeth 12 projecting rearward from the base 11.
The comb teeth 12 are fitted in the long groove 10 of the pallet A4a. The long comb teeth 12 of the pallet B4b are combined so as to slide in the long groove 10 of the pallet A4a in the traveling direction. The pallets A4a and B4b are connected to each other by a sliding structure on both sides of each pallet so as to be freely expandable and contractible.
That is, one of the two pins 14, 15 fixed laterally through the slide groove 13 at the front and rear ends of the slide groove 13 (FIG. 5) provided on the side of the pallet A4a, B4b is fixed, and the other pin 15 is a pallet B4b.
Can slide in the long hole 16. The fixed side pin 14 of the pallet B4b has a guide low on its outer end.
LA 6 is attached. The pallet B4b is provided with claws 17 on both sides of the end for engaging with holes 18 provided on the peripheral edge of the hexagonal guide wheel 7 (see the telescopic pallet reversing mechanism in FIG. 14). The portion provided with the elongated holes 16 on both sides of the pallet B4b slides along the slide grooves 13 provided on both sides of the pallet A4a to expand and contract. Reference numeral 19 denotes an upper cover that covers an upper portion of the slide groove 13.

As shown in the sectional view of the extensible pallet of FIG. 2, each of the conveyor belts 1 '(upper side) of the belt conveyors 1, 2, and 3 supports a portion of the extensible pallet 4 excluding both sides thereof, and Move 4. As shown in FIG. 2, the return side belt 1 "(lower side) of the belt conveyor is formed by the return side support roller 20 and the pinch rollers 21 with the return side belt 1" and the return side extendable pallet 4 interposed therebetween. It is designed to move with the conveyor. The passenger is moved on the transportable pallet 4 on the transport side belt 1 '.

In the method of accelerating the moving sidewalk, belt conveyors 1, 2, and 3 whose speeds are sequentially increased (or conversely, are slowed down) are arranged in series, and are sent by the frictional force between the belt and the extensible pallet 4. When transferring between the belt conveyors 1, 2, and 3, the pallets A4a and B4b constituting the pallet 4 are expanded and contracted. In other words, it expands when accelerating and contracts when decelerating. Between belt conveyors 1 and 2 or belt conveyors 2 and 3
The state of transfer between them will be described with reference to FIGS. In the drawing, the speed of the belt conveyor 2 is higher than that of the belt conveyor 1, that is, the speed is accelerated to the right. The pallet A4a on the belt conveyor 1 runs at the same speed as the belt conveyor 1, and the pallet B4b on the belt conveyor 2 is gradually pulled by the belt conveyor 2 to increase the speed. At this time, the pallet B4b is pulled by the pallet A4a connected to the front thereof and slides. The reverse is true for deceleration.

A passenger is riding on the telescopic pallet 4. It is considered that the passenger's shoes ride on the pallet A4a or the pallet B4b, or on both the pallet A4a and the pallet B4b. In any case, the conveyor 1 naturally moves from the conveyor 1 to the conveyor 2 with the change in the speed of the pallet 4. You can transfer.

The moving sidewalk requires that the belt conveyor and the telescopic pallet be turned over separately at both ends. The mechanism will be described with a telescopic pallet reversing mechanism shown in FIG. The telescopic pallet 4 leaves the belt conveyor, and the telescopic pallet A4a
The guide roller 6 provided on the side of the guide rail 5 (FIG. 1)
While proceeding while guided by 0), hexagonal guide wheel
Hole 7 provided on the pallet 7 and the pawl 17 provided on the telescopic pallet 4
Are fitted and inverted without slipping while maintaining the relative position. The inverted telescopic pallet 4 is held by a support roller 20, a pinch roller 21 and the like, and moves while being pressed against the warp-side belt.

[0013]

[Effect] A plurality of individually driven belt conveyors whose speeds are sequentially increased (or decreased) are arranged in series in the traveling direction, and a combination of a pallet A and a pallet B which are elastically engaged with each other. An endless continuous telescopic pallet that expands and contracts according to the condition is placed on a belt conveyor, the telescopic pallet is expanded and contracted by friction between the belt conveyor and the telescopic pallet, and the passenger on the telescopic pallet is accelerated (or decelerated). . Since the endless telescopic pallet is placed only on the belts of different speeds and is transferred only by friction between the pallet and the belt conveyor, it is extremely structurally simple, The operation can be reliably performed.
