Description

[0001]
[Industrial applications]
The present invention relates to an improvement of a moving sidewalk that can safely and quickly transport passengers even on relatively long journeys.
[0002]
[Prior art]
For example, in the case of a moving sidewalk installed in a place such as an airport, there is a problem that the speed of a normal moving sidewalk driven at 30 m / min or 40 m / min per minute is too slow, and it takes too much time for passengers to move. .
[0003]
Therefore, a new type of moving sidewalk that moves slowly when a passenger gets on and off the vehicle and moves at high speed in the middle portion has been desired. However, a moving sidewalk as disclosed in Japanese Patent Application Laid-Open No. 2-75594 has been proposed.
[0004]
That is, FIG. 2 is a schematic view of a moving sidewalk composed of a plurality of endless circulating belts, and FIG. 3 is a partially enlarged view of FIG. 2. In FIG. 2, an extremely flexible endless sliding belt 20 is a pair of idler rollers 25. An independent module that passes below and is always driven at a constant speed by the drive roller 31, for example, the module 2 disposed near the entrance / exit is located at a speed of 44 m / min per minute and at a position away from the entrance / exit. The module 2 is configured to be gradually accelerated or decelerated every time a passenger transfers to an adjacent module 2, such as a speed of 60 m / min or 74 m / min per minute.
Numeral 15 is an extremely small small-diameter roller having a diameter of, for example, about 30 mm to 70 mm, which is disposed at both ends of each module 2, and the gap between opposing small-diameter rollers 15 is very small, such as a child's shoe. The size is reduced to about 20 mm to 40 mm, which is smaller than that.
[0005]
Numeral 10 is a T-shaped transport plate whose upper surface is located at a lower position than the upper surface of the endless sliding belt 20 in the gap between each set of adjacent modules 2, and is omitted when the circulation speed of the endless sliding belt is high. Is described as good. Reference numeral 26 denotes a sliding plate for supporting and guiding the upper track of the endless sliding belt 20. Reference numeral 27 denotes a long endless belt constituting a central portion of a moving sidewalk that moves fastest in proximity to the high-speed module 2.
[0006]
[Problems to be solved by the invention]
However, in the case of such a variable-speed moving sidewalk, the gap between the opposed small-diameter rollers 15 must be smaller as the circulation speed of the endless sliding belt 20 is lower. Therefore, there is a possibility that the passenger conveyed in a standing posture may be caught on the orbital portion of the small-diameter roller 15 of the endless sliding belt 20 on the receiver side and smooth conveyance may not be performed.
Also, if the length of the module 2 in the acceleration / deceleration region is too short, when a tall passenger crosses over one module, it will completely straddle one module, and the endless sliding belt from a slow endless sliding belt suddenly changes to a fast endless sliding belt. (And vice versa) because they will move, which can be very dangerous.
[0007]
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a safe moving sidewalk in which passengers can be transported extremely smoothly and there is little risk of the passengers getting stuck while walking.
[0008]
[Means for Solving the Problems]
The present invention relates to a first roller and a second roller which are spaced apart from each other, a driving means, and an endless belt which passes over the first roller and the second roller and is driven by the driving means. In a moving walkway in which three or more modules having a longitudinal direction are serially arranged in a longitudinal direction and the first roller and the second roller are arranged close to each other, the module is movably longitudinally below the modules. A frame is provided, the frame has protrusions on both sides, and one module is interposed, and the end back surfaces of the modules located on both sides have receiving portions projecting toward the frame, The module is supported and guided in the vertical direction by engaging one of the projections of the frame and the module with the receiving portion.
[0009]
[Action]
According to the above configuration, even if the passenger is standing still on the belt of each module in the standing posture or walking on the belt, it is transported extremely smoothly and safely.
[0010]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an enlarged view showing an arrangement relationship of the small-diameter rollers according to the present invention, in which the same reference numerals as those in FIGS. 2 and 3 denote the same components. 15a is a small-diameter roller in the module 2a on the passenger side of the passenger, 15b is a small-diameter roller in the module 2b on the receiver side, and the height position of the central axis 16b of the small-diameter roller 15b is the height position of the central axis 16a of the small-diameter roller 15a. The endless sliding belts 20a and 20b are provided at a position slightly lower than the endless sliding belts so that passengers passing through the gap can be smoothly transported.
[0011]
By the way, it is desirable that such a moving sidewalk can change the traveling direction at any time as in the case of the escalator, but if the height position of the adjacent small-diameter roller is fixed so that a step is formed from the beginning, There is a problem that passengers cannot be transported smoothly in the opposite direction. Therefore, if the height position of the small-diameter roller can be finely adjusted according to the driving direction of the moving walkway, a very convenient moving walkway can be obtained.
[0012]
FIG. 4 is a plan view showing an example of a mechanism capable of finely adjusting the height position of the small-diameter roller. In FIG. 4, the same reference numerals as those in FIGS.
[0013]
Reference numeral 15 'denotes a small-diameter roller whose height position can be finely adjusted. The rotating shaft 16 of the small-diameter roller 15' is eccentric, for example, about the radius of the small-diameter roller 15 'in the horizontal direction, and both ends are rotatable by bearings 17. The small-diameter roller 15 ′ is supported so as to be rotatable with respect to the rotating shaft 16. A gear 18 is fixed to one side of the rotating shaft 16, and a small-diameter gear 19 directly connected to a motor (not shown) meshes with the gear 18.
[0014]
Therefore, when the small-diameter roller 15 ′ is on the receiver side, the rotating shaft 16 is rotated through the small-diameter gears 19 and 18 in a direction in which the horizontal position is lower than the opposing sender-side small-diameter roller 15, On the other hand, when the small-diameter roller 15 ′ is on the sender side, the rotating shaft 16 may be rotated by a necessary amount in a direction in which the horizontal position is higher than the small-diameter roller 15 on the opposite receiver side.
[0015]
In this case, even if the position of the small-diameter roller 15 'moves, the tension of the endless sliding belt 20 is automatically adjusted by the idler roller 25 shown in FIGS. Does not occur.
[0016]
With such a mechanism, the step between the small-diameter roller 15 'and the small-diameter roller 15 depends on the circulation speed of the endless sliding belt 20, that is, if the speed is high, the step is small, and if the speed is low, the step is relatively small. It is very easy to make the adjustment to be large.
[0017]
When the rotating shaft 16 of the small-diameter roller 15 'is eccentric in the horizontal direction as shown in FIG. 5A as in this embodiment, even if the small-diameter roller 15' is finely adjusted in any of the upper and lower directions, the adjacent small-diameter roller 15 ' In this case, the small-diameter roller 15 'is moved downward by, for example, eccentrically rotating the rotary shaft 16, and the gap between the adjacent small-diameter roller 15 is further reduced. In the case of FIG. 5B, the gap between the adjacent small-diameter roller 15 and the small-diameter roller 15 'can be easily moved at the same time as moving the small-diameter roller 15' upward (in the case of FIG. 5C). It is convenient.
[0018]
In the above description, an example in which only one of the opposed small-diameter rollers is movable has been described. However, the configuration is such that both opposed small-diameter rollers can be similarly moved [for example, FIG. 5D or FIG. In the case of), fine adjustment can be made more naturally. Further, it is also possible to configure the small-diameter roller to be rotatable and movable via a longitudinal bracket by a hydraulic device.
[0019]
On the other hand, the length of one module 2 according to the present invention is always set to a length that cannot be crossed even by a tall passenger, and on a moving sidewalk in which a plurality of modules 2 are arranged in series, Even if any passenger walks on the sidewalk, a safe moving sidewalk that smoothly passes through adjacent modules 2 and is accelerated / decelerated is obtained. It is said that a person's stride is about half of his height, so a person with a height of 180 cm has a stride of 90 cm, which is one standard.
[0020]
Next, another embodiment of the present invention will be described with reference to the drawings. 6 (a) and 6 (b) show a mechanism for finely adjusting the height position of the small-diameter roller, and FIG. 7 is a view taken along the line XX of FIG. 6 (b). The same reference numerals denote the same components.
[0021]
Reference numeral 40 denotes a support base for supporting the entire module 2, which is rotatably mounted with a central portion P as a fulcrum. Guide rollers 40 a and 40 b are provided at both ends at portions extending downward so as to be rotatable. .
[0022]
Reference numeral 50 denotes a movable frame which is movably provided in the connecting direction of the module 2 by a drive mechanism such as a rack and pinion, and has projections 50a and 50b at both ends, and guides the above-mentioned guide rollers 40a and 40b on the upper surface. It is configured to
[0023]
Accordingly, when the passenger is transported in the direction A as shown in FIG. 6A, the movable frame 50 is moved to the left so that the guide roller 40b is mounted on the protrusion 50b. Of the support table 40 is raised to the right.
[0024]
Then, the position of the small-diameter roller on the sender side of each module 2 is high, and the position of the small-diameter roller on the receiver side is relatively low, so that the passenger is transported extremely smoothly.
[0025]
On the other hand, if the passenger is transported in the direction B as shown in FIG. 6B, the moving frame 50 is moved rightward to guide the guide roller 40a on the protrusion 50a. Is placed on the support 40 of the module 2 so as to rise left shoulder.
[0026]
Then, the position of the small-diameter roller on the sender side of each module 2 is high, and the position of the small-diameter roller on the receiver side is relatively low, so that the passenger is always smoothly transported as described above.
[0027]
In the above description, the side where the relative position between the small-diameter roller on the sender side and the small-diameter roller on the receiver side is changed by adjusting the inclination of the support base 40 supporting the module 2 via the guide rollers 40a and 40b. As described above, as shown in FIG. 8 (FIG. 8B is a view taken along the line YY in FIG. 8A), a simple sliding member 40′a made of, for example, plastic is provided on the lower surface of the support base 40 ′. , 40′b, while the movable frame 50 ′ supports, for example, an L-shaped angle 51 between the small-diameter rollers of one module 2 by a load supporting member 52 so as to be movable in the longitudinal direction. The angle 51 is configured to be driven by, for example, a well-known electric screw 53, and cams 50 ′ a and 50 ′ b are provided on the upper surface of the angle 51, and sliding members 40 ′ a and 40 ′ b of the support base 40 ′ are provided. And the cams 50'a and 50'b of the movable frame 50 ' Even if it is a simple mechanism which pushes up either of the sliding members 40'a and 40'b and tilts the support 40 'appropriately, there is no practical problem if this mechanism is not operated frequently. Does not occur.
[0028]
Such a step between the modules becomes more important as the circulation speed of the endless sliding belt 20 is lower, and it is not necessary to provide a step in a region where the circulation speed is high. In the case of a variable speed moving sidewalk composed of 2, 2 ", for example, a structure in which the height of only the module 2" can be adjusted may be considered. Of course, all the modules 2 and 2 "may have an adjustable structure.
[0029]
In order to provide a structure in which a plurality of modules can be adjusted in height as described above, for example, the module is configured as shown in FIG. 10 (FIG. 10B is a view taken along the line ZZ in FIG. 10A). be able to.
8, the same reference numerals as those in FIG. 8 denote the same components, but reference numerals 51a and 51b denote angles which are divided and arranged on both right and left sides of the endless sliding belt 20, and extend over a plurality of modules 2, 2 ''. It is a long member provided.
[0030]
These angles 51a and 51b are movably supported by a load support member 52, as in the case of FIG. The angle 51a is directly driven by the electric screw 53.
[0031]
A rack 511a is provided at an intermediate portion of the angle 51a, and a rack is similarly provided on the angle 51b side.
[0032]
Reference numeral 54 denotes a shaft arranged so as to straddle the angles 51a and 51b. Pinions 54a and 54b meshing with the racks 511a and 51b of the angles 51a are rotatably attached to both ends.
[0033]
Then, the angle 51a, cam 50'A ₁ at a predetermined position of the module for height adjustment on the upper surface of the _{51b, 50'b 1, 50'a 2,} 50'b 2 is provided.
[0034]
Therefore, if the electric screw 53 is operated to move the angle 51a in a required direction, that is, in the left or right direction in FIG. 10, the angle 51b is moved in the same direction as the angle 51a by the rack and pinion mechanism in the intermediate portion. Go to, so that the cam 50'b _1, 50'b ₂ or 50'a _1, 50'a ₂ is a corresponding predetermined module 2 pushes up the sliding member to "only necessary inclination of the support base 40 ' Obtainable.
[0035]
【The invention's effect】
As described above, according to the present invention, the transfer of passengers from the sender side to the receiver side between each module is performed extremely smoothly, and even if the driving direction of the moving sidewalk is reversed, there is no problem. It is possible to obtain a moving sidewalk that does not cause any problems. Moreover, even if the passenger walks on the belt with a stride, a safe moving sidewalk without stumbling or staggering can be obtained.
