[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving walkway installed in public facilities such as airports and station yards, and more particularly to a moving walkway for transporting users in two opposing directions.

[0002]

2. Description of the Related Art FIGS. 14 to 22 show an example of a moving sidewalk proposed in recent years. This moving sidewalk has two rails 101 arranged in a ring shape, and a user can board the train. The pallet includes a large number of flat pallets 102 that can rotate clockwise along the rails 101, and screw rods 103 and 104 and an endless chain 105 that can move the pallets 102.

[0003] The rail 101 is composed of two linear transport sections 1A and 1B arranged in parallel and horizontally to each other, and a semicircular turning section 1C connected to one end of both transport sections 1A and 1B.
And a semicircular turning part 1D connected to the other ends of the two conveying parts 1A and 1B.

[0004] Further, the revolving parts 1C, 1D of the rail 101
Is entirely covered from above by platforms 2A and 2B for getting on and off.

A traveling roller 106 that can roll on the rail 101 is provided on the lower surface of the pallet 102 near the front end in the moving direction.
Are pivotally supported via a bracket 107.

[0006] The rear end of each of the pallets 102 in the moving direction is slidably overlapped with the front end of another pallet 102 adjacent to the rear side. Separation is allowed, and the rear end of each pallet 102 is supported by the succeeding other pallets 102 to form a continuous sidewalk surface.

The screw rod 103 is connected to the rail 101
Of the transport unit 1A (the upstream side in the pallet moving direction) of the transport unit 1A and the pivot unit 1 of the transport unit 1B of the rail 101.
It is disposed so as to be positioned in parallel between the left and right rails 101 at two places, that is, at a position closer to D (upstream side in the pallet movement direction).

The end of the screw rod 103 is pivotally supported by a fixed structure such as a floor slab by a bearing 108, and is driven to rotate by a motor 109.

The thread 1 of the screw rod 103
03a is set so that the pitch P gradually increases from a portion closer to the pallet movement direction toward the downstream portion in the pallet movement direction.

The screw rod 104 is connected to the rail 101
Of the transfer unit 1A (the downstream side in the pallet moving direction) of the transfer unit 1A and the turn unit 1 of the transfer unit 1B of the rail 101.
It is disposed so as to be located between the left and right rails 101 at two places, ie, at a position close to C (the downstream side in the pallet movement direction).

The screw rod 104 is also driven to rotate by a motor (not shown), similarly to the screw rod 103 described above.

The thread 1 of the screw rod 104
04a is set such that the pitch P gradually narrows from a portion closer to the pallet movement direction toward the downstream portion.

Further, a transfer roller (thrust transmitting member) 111 is provided at a lower end of a support table 110 provided on a lower surface of a portion of each pallet 102 near the front end in the movement direction.
3 and 104, the screw rods 103 and 104 are pivotally supported so as to be able to engage with the screw threads 103a and 104a. When the moving rollers 111 are engaged with the screw threads 103a and 104a, the screw rods 103 and 104 are rotated. The screw rod 1
Moving roller 111 in a direction corresponding to the rotation of
Is sent out, and the pallet 102 moves along the transport sections 1A and 1B of the rail 101.

When the moving roller 111 is engaged with the thread 103a, the moving speed of the pallet 102 is gradually increased toward the downstream side in the moving direction, and the moving roller 111 is moved to the thread 104a. When engaged, the speed is gradually reduced toward the downstream side in the movement direction.

The endless chain 105 is composed of a sprocket 112 pivotally supported at an end of the screw rod 103 on the downstream side in the pallet moving direction and a sprocket pivotally supported at an end of the screw rod 104 on the upstream side of the pallet moving direction. 113, and is driven to rotate by a motor 114.

A plurality of pulling claws 115 are provided on the outer peripheral surface of the endless chain 105 at equal intervals.

Further, on the lower surface of each pallet 102, a locking member 116 which can be engaged with the traction claw 115 of the endless chain 105 is attached, and this locking member 116 is attached to the traction claw 115 of the endless chain 105. When the endless chain 105 is made to go around in a state where it is engaged with the pallet 102, the locking member 116 is sent out in a direction corresponding to the turn of the endless chain 105, and the pallet 102 is moved to the conveying portions 1A and 1A of the rail 101.
It will move along B.

That is, the pallet 102 on which the user rides from the platforms 2A and 2B
Thread 10 of screw rod 103 with which 1 is engaged
It is gradually accelerated according to the pitch P of 3a.

Next, by the movement of the pallet 102, the engagement between the thread 103a and the moving roller 111 is released, and the locking member 1 is attached to the pulling claw 115 of the endless chain 105.
When the pair 16 is engaged, the pallet 102 moves at a constant speed according to the rotation speed of the endless chain 105.

Further, by the movement of the pallet 102, the engagement between the pulling claw 115 and the locking member 116 is released, and the moving roller 111 is connected to the thread 10 of the screw rod 104.
4a, the pallet 102 is moved to the thread 104a.
Is gradually decelerated according to the pitch of the vehicle.

Further, at the downstream end of the conveyors 1A and 1B of the rail 101 in the pallet moving direction, the moving rollers 111 are provided.
102 disengaged from the thread 104a
The front end of the movement of another pallet 102 following the pallet 102 comes into contact with the support table 110.

As a result, the pallet 102, which is moving in the pallet moving direction of the conveying sections 1A, 1B of the rail 101 by the screw rod 104, moves the other pallets 102 in front of the pallet 102 to the turning sections 1D, 1B of the rail 101.
It is extruded from 1C to the most upstream part in the pallet movement direction of the transport units 1B and 1A.

[0023]

In the moving sidewalk shown in FIGS. 14 to 22, the screw rods 103 and 104 are provided in order to prevent a user riding the pallet 102 from feeling uncomfortable acceleration and deceleration. It is necessary to make the length longer so that the rate of change of the pitch P of the threads 103a and 104a per unit length is gentle.

However, when the moving roller 111 engages with the threads 103a and 104a,
The screw rods 103, 104 cannot be pivotally supported by the bearings 108 except for both ends thereof.
If the length 104 is lengthened, deflection due to its own weight occurs, and it becomes impossible to secure the engagement between the screw threads 103a, 104a and the moving roller 111.

Therefore, the speed of the pallet 102 moving at a constant speed in the intermediate portion between the transporting sections 1A and 1B depends on the length of the screw rods 103 and 104 and the number of threads 10 per unit length.
It is determined by the rate of change of the pitch P between 3a and 104a, and the user cannot be transported efficiently.

The moving roller 111 is engaged with the threads 103 a and 104 a of the screw rods 103 and 104, and the engaging member 1 is engaged with the pulling claw 115 of the endless chain 105.
Due to the structure in which the pallets 16 are engaged, there is a concern that minute vibrations may occur on the pallet 102 and noise caused by the vibrations.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a moving sidewalk that suppresses minute vibration and noise of a pallet on which a user rides and allows the pallet to slowly accelerate or decelerate over a long distance. It is an object.
