FIGS. 10 and 11 show an example of a variable-speed moving sidewalk proposed in recent years. This moving sidewalk has two rails 11 arranged in an annular shape, and allows a user to board. A large number of flat pallets 3 that can rotate clockwise along the rails 11, and screw rods 13, 14, 1 that can move the pallets 3 in the extension direction of the rails 11.
5, a step 101 provided at a position where the user gets on the pallet 3, and a step 102 provided at a position where the user gets off the pallet 3.

[0008] The rail 11 comprises a linear transport section 1A, 1B arranged in parallel and horizontal with each other, and both transport sections 1A, 1B.
It comprises a semicircular revolving part 1C connected to one end of 1B, and a semicircular revolving part 1D connected to the other ends of both transporting parts 1A, 1B.

Outside the rails 11 radially outside the turning parts 1C and 1D and inside the rails 11 radially inside,
A guide rail 12 bent in a semicircular shape is arranged along the rail 11.

[0010] Immediately above the turning parts 1C and 1D of the rail 11 and the guide rail 12, platforms 2A and 2B for getting on and off are installed substantially horizontally so as to form a gap between the rails 11 and 12. Have been.

At the lower part of the pallet 3, a traveling roller (not shown) which can be rolled in contact with the rail 11 from above, and is located on the front end side in the moving direction with respect to the traveling roller and is lower than the guide rail 12. A roller for tilt angle correction (not shown) that can roll in contact with the side is mounted.

These many pallets 3 are arranged such that the traveling rollers are in contact with the upper surface of the rail 11 and their rear ends overlap the front ends of the other pallets 3 which are adjacent on the rear side. .

As a result, the transport sections 1A, 1A of the rail 11
In B, the approach and separation of the adjacent pallets 3 are allowed, and the rear end of each pallet 3 is supported by the following other pallets 3.

In the swiveling portions 1C and 1D of the rail 11, the adjacent pallets 3 approach and the rollers for correcting the inclination roll on the lower surface of the guide rail 12, so that each pallet 3 is inclined forward and the pallets 3 are tilted forward. The front end of another subsequent pallet 3 can come into contact with a projection member (not shown) fixed to the lower surface of the pallet 3.

The screw rod 15 is disposed at a portion of the rails 11 closer to the pallet moving direction upstream of the conveyors 1A and 1B (a portion closer to the swiveling portions 1C and 1D) so as to be positioned in parallel between the left and right rails 11. I have.

The thread grooves of the screw rod 15 are formed at equal intervals where the pitch of the portion closer to the pallet moving direction upstream is narrow.
Further, the pitch is gradually increased in the intermediate portion in the pallet moving direction, and further, the pitch of the portion on the downstream side in the pallet moving direction is formed to have a wide equal interval.

The pitch of the thread grooves of the screw rod 14 is equal to the pitch of the thread grooves in the portion of the screw rod 15 on the downstream side in the pallet moving direction (the pitch of the thread grooves is wide at equal intervals) over the entire length of the rod. Part).

The screw rod 13 is disposed at a portion of the conveying portion 1A, 1B of the rail 11 on the downstream side in the pallet moving direction (a portion near the turning portion 1D, 1C) so as to be positioned in parallel between the left and right rails 11. I have.

The screw grooves of the screw rod 13 are formed at equal intervals where the pitch of the portion near the upstream in the pallet moving direction is wide.
Further, the pitch is gradually reduced in the intermediate portion in the pallet moving direction, and furthermore, the pitch of the portion on the downstream side in the pallet moving direction is formed to have a narrow equal interval.

Further, on the pallet 3, a moving roller (not shown) which can be engaged with the screw grooves of the screw rods 13, 14, 15 is pivotally supported so as to be located immediately below the above-mentioned projecting member. Have been.

When the screw rods 13, 14, 15 are rotated in a state where the transfer roller is engaged with the thread groove, the transfer roller is sent out in a direction corresponding to the rotation, and the pallet 3 is moved to the rail 11 Move along the transport sections 1A and 1B.

The pitch of the screw groove of the screw rod 15 and the number of rotations by the motor are
Pallet 3 in which the moving roller is engaged with the thread groove of
After moving at a low speed (30-40 m / min) at a constant speed, 0.05

0m) so as to move at a constant speed.

The pitch of the thread groove of the screw rod 14 and the number of rotations by the motor are
Pallet 3 in which the moving roller is engaged with the thread groove of
It is set to move at a constant speed at a high speed (90-120 m / min).

Further, the pitch of the thread groove of the screw rod 13 and the number of rotations by the motor are
Pallet 3 in which the moving roller is engaged with the thread groove of
After moving at a constant speed at a high speed (90-120 m / min), 0.0
It is gradually decelerated at a deceleration of 5 G or less, and at a low speed (30 to 4
0m) so as to move at a constant speed.

Therefore, when the pallet 3 is accelerated, the overlap margin of the adjacent pallets 3 decreases, and when the pallet 3 is decelerated, the overlap margin of the adjacent pallets 3 increases.

Furthermore, the adjacent pallets 3 before and after are
The rails 11 are connected to each other via a spring buffer mechanism and a chain (not shown).
The pallet 3 located between the pallets 4 and 15 is pulled by the other pallets 3 moving at a constant speed (90 to 120 m / min) by the screw rods 13 and 14 via a spring buffering mechanism and a chain. The pallet 3 located at the revolving parts 1C and 1D is pushed out by the subsequent pallet 3 moving at a constant speed (30 to 40 m / min) by the screw rod 15 with the chain loosened.

The entrance step 101 is attached to the platforms 2A and 2B so as to approach the turning parts 1C and 1D of the conveying parts 1A and 1B of the rail 11 (the part near the upstream end in the pallet moving direction). Step 1
02 is a turning section 1D of the transport section 1A, 1B of the rail 11;
It is attached to the platforms 2B and 2A so as to reach a portion closer to 1C (a portion closer to the downstream end in the pallet moving direction).

Further, since the moving speed of the pallet 3 in each part of the transporting sections 1A and 1B is different, the pallet 3 moves independently of the low speed moving section, the acceleration section, the high speed moving section, the decelerating section and the low speed moving section. A handrail device is installed, and the handrail belt 108 of the moving handrail device is rotated so as to correspond to the moving speed of the pallet 3 so that a user can board the pallet 3 in a stable state.
