Definitions
- the present invention relates to a conveyor device such as an X scale or a moving sidewalk.
- Competing devices for moving and moving are provided with a plurality of steps provided with step openings.
- the plurality of steps are integrated with the step chain by connecting the steps provided at each step with a predetermined pitch by an endless step chain, and the step chain is chained. All the steps are configured so that they can move synchronously and without gaps by being driven by the drive mechanism.1
- These steps are steps with step rollers formed on a structure. This step is engaged with the guide rail, and is supported by the guide rail so that it moves in a circular manner between the entrance and the exit. Since it is common to move in the horizontal direction, the steps are sometimes referred to as treads in particular, but in this specification, the notation is also used as the steps for moving sidewalks

'To move.
- the step roller 5 that moves on the arc portion 32 of the step guide rail 3 at the pitch circular velocity Vt ' is referred to as an arc roller here for convenience.
- the step roller adjacent to the arc part la moves along the curving part 13.
- the robot moves at a constant speed (average speed V).
- the step roller 5 which is expected to have a constant speed by the second roller on the front side of the curved portion 13 from the arc portion roller, is fixed at a constant speed for convenience.
- the step roller between the circular arc opening and the constant speed roller passes through the curved portion 13 while the step roller is passing through the curved portion 13.
- the speed fluctuations that occur in the roller are completely absorbed by the change in the height position of the step roller according to the shape of the bent portion 13, and the moving speed of the constant speed roller is accurately adjusted to the constant speed (average speed V ').
- step chain 7 is 13.3.
- the P-roller center locus described above is calculated from the straight line part 3 1 of the step guide rail 3 to the curved part 3
- the stepped guide rail is used because the arc part 32 is not restricted by the number of teeth such as the drive sprocket 9. 3 straight part 3 1 mi; L
- the radius of curvature of the arc tangent to the linear portion 31 of the step guide rail 3 is ⁇ : If R 1 is 50 O mm, the radius of curvature is subtracted from the radius of curvature R 1.
- the offset amount ⁇ is set to the same value (1.806 mm) as the optimum value (upper limit value) S max of the offset amount obtained by adding the height position of the straight line portion 31 in the above example. Then, the curved portion 31 has a descending curve that gradually descends from the straight portion 31 to the arc portion 32 having the radius of curvature R2.
- the moving speed of the step roller 5 can be kept almost constant, and the vibration of the step 5 can be reduced. It is possible to suppress it and ensure good riding comfort.
- the step rollers are linear.
- the speed unevenness of the step roller caused by passing through the bend is absorbed, so that the step caused by the uneven speed of the step roller is absorbed. Vibration can be effectively suppressed to ensure a good ride quality.Also, the height difference required to absorb unevenness in the speed of the step rollers is extremely small. This is also advantageous in realizing a thinner device.
