Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a variable speed mechanism for a moving body.
[0002]
[Prior art]
Conventionally, there are two types of moving sidewalks: a pallet type for placing passengers on a pallet and a belt type for placing on a rubber belt.
[0003]
[Problems to be solved by the invention]
In particular, it is very difficult to change the moving speed of pallets, handrails, etc. on an accelerating moving sidewalk that moves at a relatively slow speed of about 30 meters per minute in the boarding area and in the middle area. Many of the proposals that have been proposed so far use very complex mechanisms and are far from practical.
[0004]
The present invention has been made in view of the above points, and an object of the present invention is to provide a mechanism for changing the speed of a moving body with a very simple configuration.
[0005]

DETAILED DESCRIPTION OF THE INVENTION
The present invention proposes a simple mechanism capable of freely changing the speed of a roller for guiding a moving body.
[0007]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 is an overall view when the present invention is applied to a pallet-type moving sidewalk, FIG. 2 is an explanatory view showing a variable speed mechanism of the pallet in FIG. 1, FIG. 3 is a view taken along line XX in FIG. FIG. 3 is a view taken in the direction of arrows Y-Y in FIG. 2.
[0008]
In the figure, 1 is a drive machine, 2 is a drive sprocket driven by a drive machine 1 through drive chains 3a and 3b and an idler sprocket 1a, and 4 is a driven sprocket that is constantly receiving force in the direction of the arrow by a tensioning device 5. Reference numeral 10 denotes a transfer chain wound endlessly around the drive sprocket 1 and the driven sprocket 4 and always moves at a constant speed.
[0009]
Reference numeral 11 denotes a shaft which is fixed to the transfer chain 10 at a predetermined interval and can freely rotate. For example, a conical roller 20 is a pallet placed on the roller 11 and a plurality of pallets are provided. . Reference numerals 21 and 22 denote, for example, octagonal sprockets that invert the pallet 20 and are arranged outward from the drive sprocket 2 and the driven sprocket 4, respectively.
[0010]
A rail 30 is arranged over the entire traveling area of the pallet 20 so as to always contact the roller 11. The roller is located near the tip of the conical shape in the middle part of the moving sidewalk and near the conical root near the entrance / exit. 11 is arranged so as to touch a location on the top. Reference numeral 50 denotes a regulating device for suppressing excessive movement of the pallet 20.
[0011]
In such an apparatus, the region where the rail 30 contacts the tip of the conical roller 11 of the transfer chain 10 that moves at a constant speed, that is, the roller 11 rotates at a high speed in the middle portion, and the rail at the root portion of the roller 11. Since the roller 11 rotates at a low speed near the area where the door 30 comes into contact, that is, near the entrance / exit, the pallet 20 placed on the roller 11 moves at a high speed in the middle portion, and at a low speed near the entrance / exit. It will perform the ideal movement of moving with.
[0012]
For this reason, as shown in FIG. 4, if the rail 30 is arranged gradually toward the middle of the pallet 20 at the entrance / exit and toward the both ends of the pallet 20 as it goes to the middle part, there is no problem. You can get a moving walk without acceleration.
[0013]
Here, the roller 11 does not have the conical shape as described above, but may have a stepped roller 11 ′ as shown in FIG. That is, the rollers 11'a, 11'b, 11'c, 11'd, 11'e, and 11'f having different outer diameters are integrally formed, and the rail 30 'in contact with the rollers is made 30'a, 30'. If it arrange | positions like b, 30'c, 30'd, 30'e, 30'f, the speed of the pallet 20 mounted on the roller 11 'can be changed similarly.
[0014]
In any case, as shown in FIG. 3, in the region where the speed is high, the pallets 20 are spaced apart from each other and a gap is formed between them. For example, a pallet structure as proposed in Japanese Patent No. 2845747 It is also a method to adopt.
[0015]
That is, as shown in FIGS. 6A and 6B, the pallet 21 is configured to be an extendable pallet 20 ′ in which the pallet 22 is slidably attached to the hollow portion 21a.
[0016]
Next, FIGS. 7A and 7B show an embodiment when the present invention is applied to a moving handrail on a moving sidewalk. FIG.7 (b) is a ZZ line | wire arrow line view of Fig.7 (a). In the figure, the same components as those in FIGS. 1 to 4 indicate the same components.
[0017]
A plurality of handrails 60 are placed on the roller 11 via the bracket 61, and a plurality of handrails are arranged. 62 is a roller provided at one end of the moving handrail 60, and 70 is a guide rail for guiding the roller 62, and guides the moving handrail 60 so as to protrude freely as shown in the figure. (Of course, it may be configured not to protrude like a normal moving handrail)
[0018]
It is obvious that the roller 11 in this case can achieve the same function even if it has a stepped shape as described above.
[0019]
【The invention's effect】
As described above, according to the present invention, whatever speed is desired to be moved at a variable speed, the speed of the moving object can be changed very freely with a simple configuration by setting the roller for guiding the variable speed. It can be done.
