Abstract

In a moving walk wherein the relative positions at both ends of a module can be regulated, clearance closing members, such as second skirt panels are provided below skirt panels so as to eliminate the possibility that the foot or clothes of a passenger are caught in the clearance between a belt and the skirt panel, even when the belt is displaced vertically. This member is supported movably following up the movement of the belt. The relative positions at both ends of the module are regulated by utilizing the tensile force produced due to the rotation of driving rollers instead of the drive of a conventional large-scale machine. The back side of the belt is divided into a portion of a low coefficient of friction guided by a support plate, and a portion of a high coefficient of friction driven by the driving rollers so that the belt has a low traveling resistance when the belt moves on a sliding plate, and a large frictional force when the belt is frictionally driven on the driving rollers, whereby the belt is driven efficiently.

Description

Description Moving walkways and their driving devices

The present invention relates to a moving sidewalk that can quickly and safely transport passengers even in a relatively long process. Background art

For example, in the case of an airport, where a moving walkway is installed in a large and large place such as a large shopping center, the speed is about 3 Om or 4 Om per minute, as in the case of a conventionally used moving walkway. There was a problem with speed driving that the speed was too slow and the passengers took too long to move.

Therefore, a new type of moving sidewalk that moves slowly when passengers get on and off and moves at high speed in the middle has been long-awaited. However, a moving sidewalk as described in Japanese Patent Application Laid-Open No. 2-755590 is as follows. Has been proposed.

FIG. 2 is a schematic view of a moving sidewalk including a plurality of endless circulating belts, and FIG. 3 is a partially enlarged view of FIG. In the figure, reference numerals 2 and 2 ′ indicate a thin and extremely flexible endless sliding belt 20, which passes under a set of guide rollers 25 and is always driven at a constant speed by a drive roller 30. The module 2 located near the entrance / exit moves at a low speed, and the module 2 'located far from the entrance / exit becomes faster as the distance from the entrance / exit becomes higher. It is configured to gradually accelerate or decelerate each time a passenger transfers to the adjacent module 2 or 2 '. That is, the module 2 has a getting-on / off belt, and the module 2 'has an acceleration / deceleration belt.

Reference numeral 15 denotes a very small roller, for example, having a diameter of about 3 Omm to 7 Omm, which is disposed at both ends of each module 2 or 2 ′, and is effective between adjacent portions of the upper track. The spacing is reduced to about 20 to 40 mm, which is even smaller than the length of a shoe that is fairly small, such as a child's shoe. Reference numeral 10 denotes a transport plate having a T-shaped cross section which is disposed in the gap between each pair of adjacent modules 2 or 2 ′ such that the upper surface is lower than the upper surface of the endless sliding belt 20. It is described that the transfer plate 10 may be omitted when the circulation speed of the endless sliding belt is high.

Reference numeral 26 denotes a sliding plate that supports and guides the upper track of the endless sliding belt 20, and reference numeral 27 denotes a central portion of a moving sidewalk that moves fastest in proximity to the high-speed module 2 ′. 2 shows a long main circulation belt constituting the above.

However, in such a variable-speed moving sidewalk, the gap between the opposed small-diameter rollers 15 must be reduced as the circulation speed of the endless sliding belt 20 is lower. When inserted, the gap becomes wider by that amount, and the passenger who is conveyed in a standing posture may hang over the orbital part of the small-diameter roller 15 of the endless sliding belt 20 on the receiver side, preventing smooth conveyance. There is.

On the other hand, the applicant has proposed in Japanese Patent Application No. 7-273595, a variable-speed moving walkway that smoothly transports passengers without using a transport plate.

As shown in FIG. 4, the moving sidewalk changes the relative height position of the opposed small-diameter rollers 15a and 15b of the adjacent modules 2a and 2b. In other words, the small-diameter rollers 15b of the module 2b on the receiver side are lowered so that the transported object is transported smoothly.

As in the case of escalating evening, on a moving sidewalk where the traveling direction can be switched at any time, the positional relationship between the small rollers 15a and 15b of the adjacent modules 2a and 2b may change accordingly. Must be configured.

Such a mechanism that relatively changes the positional relationship is naturally desirable to not require a special Ml device. Normally, a very large device such as a power cylinder is required.

Also, in the case of a belt-type moving sidewalk, as shown in Fig. 5, a belt 2 for transporting personnel that is wide enough to enter under the well-known scar panels 35 that are erected on both sides. Since the belt 20 is generally supported and guided and moves in the traveling direction, if the belt 20 is configured to be movable up and down as described above in the reversible operation specification, the fixed skirt panel 35 and the belt The gap 35 from 20 is determined by the position of belt 20. When the belt 20 is set at a lower position, the gap 35 a becomes about 1 Omm larger than that in FIG. 6 (a), as shown in FIG. 6 (b). Forces such as passenger's feet <I, which is more likely to be pinched.

Furthermore, in a belt-type moving sidewalk, it is preferable that the running resistance is as low as possible when the belt moves in a sliding manner, and that the belt has a large frictional force when the belt is driven by friction on a driving roller for efficient driving. However, a drive device satisfying such contradictory requirements has not been proposed.

The present invention has been made in view of the above points, has extremely simple height position adjusting means, and has a gap between a skirt panel and a passenger's feet or clothes even when a belt moves in a vertical direction. The purpose of the present invention is to provide a moving sidewalk that is less likely to be pinched. Another object of the present invention is to provide a driving device for a moving sidewalk that can perform efficient driving by satisfying the above contradictory requirements.

The moving sidewalk of the present invention has, for example, one or more of the following configurations.

(1) A second skirt panel is provided below the skirt panel, and the second skirt panel is supported so as to be able to move following the belt.

(2) Adjust the relative position of both ends of the module using the belt tension generated by the rotation of the drive roller.

(3) The reverse side of the belt is divided into a part with a low coefficient of friction guided by the support plate and a part with a high coefficient of friction driven by the drive port, to satisfy conflicting requirements at the same time. Hereinafter, embodiments of the moving walkway of the present invention having these configurations will be described with reference to the drawings, but the present invention is not limited to these embodiments.

FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 7 is a partial side view of FIG. In the drawings, the same reference numerals as those in FIGS. 2 to 6 denote the same members or portions, and reference numeral 50 denotes a smooth sliding of an angle 51, which will be described later, provided at a predetermined interval in the longitudinal direction of the truss 5. 5 shows a supporting device for supporting the member 52 so as to be movable in the longitudinal direction via a member 52. The angle 51 is supported in the direction of movement of the moving walkway by at least one module 2 or 2 'or a plurality of adjacent modules, and cams 51 a, 51 are provided on the upper surface on both ends of the corresponding module. b is provided.

Reference numeral 53 denotes an angle provided on both sides of the sliding plate 26, and smooth sliding members 53a and 5313 are provided on the lower surfaces on both ends of the corresponding module. Reference numeral 54 denotes a support member provided so as to stand on both sides of the sliding plate 26, and at the upper end thereof, a second strut panel 55 according to the present invention is fixed behind a skirt panel 35 fixed thereto. The escalator is provided movably in the width direction so as to partially overlap. That is, the second skirt panel 55 has a very small gap with the skirt panel 35. It is attached to the support member 54 so that it can be adjusted via a long hole or the like so as to reduce the force.

Reference numeral 60 denotes an electric cylinder that moves the angle 51 in the longitudinal direction of the escaping force, and the left and right angles 51 are connected (not shown) at arbitrary positions and are synchronized. Driven.

In such a configuration, by operating the electric cylinder 60 and moving the angle 51 in a required direction, that is, in the left or right direction in FIG. As a result of 1 b pushing up one end of the sliding plate 26 through the sliding member 53 a or 53 b, the module 2 or 2 ′ is inclined about the P portion as a seesaw.

Then, as shown in FIG. 4, a predetermined level difference occurs between the adjacent modules, but according to the relationship between the belt 20 and the skirt panel 55, the scart panel 55 slides as shown in FIG. Since it moves up and down following the board 26, the gap 55a between the skirt panel 55 and the belt 20 is always constant, thus ensuring safety for passengers.

In the above description, the structure in which the scar panel 55 is attached to the support member 54 has been described. However, the support member and the skirt panel may be integrated, and in short, follow the belt 20. The object of the present invention is attained if a scar panel which moves in the vertical direction is provided.

In the above embodiment, the skirt panel 55 is configured to be movable in the width direction. However, the skirt panel 35 may be configured to be movable in the width direction. Adjustment of the relative position of 5 and skirt panel 5 5 may be performed on either side.

As described above, according to the present invention, the transfer force of the passenger from the sender side to the receiver side between the modules <extremely smooth, and even when the driving direction of the moving sidewalk is reversed, A moving walkway that is less likely to cause safety issues can be obtained.

By the way, for example, a moving sidewalk as shown in FIG. 9 or FIG. 10, that is, a plurality of independent belt conveyors 4 a, 4 b, 4 c, 4 d, 4 e, 4 ί or 3 a, 3 b, 3c, 3f are arranged in series in the longitudinal direction, and the belt conveyor 4a (or 3a) located near the entrance / exit is moved at a low speed, and the belt located at a position away from the entrance / exit Conveyors 4b to 4f (or 3b, 3c, 3f) are operated at a higher speed as they get farther from the entrance, and gradually increase or decrease as passengers transfer to the adjacent belt conveyor. In the case of a variable speed moving sidewalk constructed as described above, the configuration shown in FIG. 11 (A) or FIG. 11 (B) can be considered as an example of the configuration of the belt conveyor used for this.

In FIG. 11 (A), reference numeral 70 denotes an endless guide roller 71, 72, a drive roller 73, a tension roller 74 and guide rollers 75, 76, 77 rotatably provided at both ends of the belt conveyor. Reference numeral 78 denotes a sliding plate that supports and guides the outward side of the belt # 0.

The tension roller 74 is rotatably provided on a bracket 74a, and the bracket 74a is integrated with a female screw 74b. The female screw 74b is screwed to a screw rod 74c. A nut 74d is fixed to the screw rod 74c. Therefore, by rotating the nut 74 d and turning the screw rod 74 c, the female screw 74 b is moved to the left and right, and the tension roller 74 supported by the bracket 74 a is moved to the belt 70. In FIG. 11 (B), reference numeral 74'c denotes a threaded rod which is vertically supported for rotation, and a nut is provided above the threaded rod 74'c. 74'd is fixed, and a movable nut 74'e is screwed into the middle part.

Reference numeral 74'f denotes a link having one end rotatably mounted on a movable nut 74'e, and the other end is rotatably provided on a tension roller 74 'via a bracket 74'a. Other symbols indicate the same members as in FIG. Therefore, in the case of FIG. 11 (B), the movable nut 74'e is moved up and down by rotating the nut 74'd and turning the screw rod 74'c, and the movable nut 74'e is moved up and down. The up and down movement of 74 'e can be converted to the right and left movement of the tension roller 74' via the bracket 74 'a by the link 74' f and adjusted so that sufficient tension is applied to the belt 70. is there. That is, when the nut 74'd is turned counterclockwise as indicated by the arrow, the movable nut 74'e moves downward, and as a result, the tension roller 74'force moves to the left and moves to the belt 70. When sufficient tension is applied and conversely, nut 74'd is turned clockwise, the movable nut 74'e moves upward, and the tension roller 74 'moves to the right. The tension of the belt 70 can be reduced.

With the configuration as shown in FIG. 11 (B), the operation of the nut 74'd can be easily performed from above, so that the adjustment work force is very easy.

Next, a mechanism for adjusting the height position of both ends of the module will be described. That is, in the present invention, the height position switching device can be configured as follows instead of a large-scale device as shown in FIG.

Numeral 79 in FIGS. 11 (A) and (B) and FIG. 12 which is a cross-sectional view taken along the line A—A in FIG. 11 (A) indicates a buckle device, for example, which constantly applies a biasing force. The pin 79b is projected outward by the panel force of the spring 79a, and when a voltage is applied to the electromagnetic solenoid 79c, the pin 79b is retracted. It has been. Although the figure shows an example of a T-shaped electromagnet, an I-shaped electromagnet may be used.

On the truss side facing this locking device 79, there is a hole 80.80 'into which the pin 79b fits, and the pin 79b fits into the hole 80,80'. In this state, the module is prevented from rotating. Reference symbol P indicates a pivot point of the module.

The operation of the module height position adjusting mechanism including the lock device 79 is as follows.

First, to move the transported object from left to right, if you want to lower the left end of this module relatively and raise the right end, apply a voltage to the electromagnetic solenoid 79 c of the lock device 79. Then, the pin 79 b is pulled out of the hole 80 ′ to release the engagement, and then the driving roller 73 is rotated counterclockwise.

Then, larger than ₂ tension of the belt 7 0 T, module takes the rotation mode one member Bok counterclockwise direction Ρ point as a fulcrum, the module left end downwardly until it hits the stopper (not shown) You will lean.

At this time, release the voltage of electromagnetic solenoid 79 c of The pin 79b is protruded outward by the panel force of 79a to engage with the hole 80, and the module is hooked to prevent rotation.

Thereafter, the driving roller 73 is rotated clockwise so that the belt 70 moves in the normal movement direction, and the conveyance of the object is started.

In this way, the receiver side of the module is held at a low position, and the sender side is held at a high position, and the object to be transferred is transported extremely smoothly.

To move the transported object from right to left, if you want to raise the left end of the module relatively and lower the right end, the voltage is also applied to the electromagnetic solenoid 79 c of the lock device 79. Is applied, the pin 79b is withdrawn from the hole 80 to disengage, and then the drive roller 73 is rotated clockwise.

Then, in this case, the tension becomes greater than the tension T _{2 of the} belt 70, so that a rotational moment is applied to the module in the clockwise direction with the Ρ point as a fulcrum, and the right end of the module hits a stopper (not shown). It will lean down.

Next, release the voltage of the electromagnetic solenoid 7 9 c of the lock device 7 9, and

The pin 79b is protruded outward by the spring force of 9a to engage with the hole 80 ', and the module is hooked to prevent rotation.

Thereafter, the driving roller 73 is rotated counterclockwise so that the belt 70 is moved in the normal moving direction, and the conveyance of the object is started.

In this way, the receiver side of the module can be held low and the sender side can be held at a high position in accordance with the moving direction of the object to be transferred, and smooth transfer can always be achieved.

In this embodiment, the lock device 79 is provided on the movable side. However, the lock device may be provided on the fixed side, and the lock device may be driven by air pressure instead of the electromagnetic solenoid. Alternatively, hydraulic pressure may be used, and the locking means is not limited to the above embodiment.

Further, the lock device may be provided not only at one place but also at a plurality of places.

According to the present invention described above, a large-scale driving device and mechanism are not required at all for setting the relative positions of both ends of the module, and the setting can be performed by an extremely simple mechanism and method. In this way, it is possible to obtain a moving sidewalk that enables smooth transportation at all times even when the driving direction is changed.

Next, a driving means for a moving road using a belt that generates low frictional resistance when the belt moves on the sliding plate 78 and generates a large frictional force when driven by a driving roller. , To be described.

FIG. 13 is a cross-sectional view showing a state in which a belt 70 ′, which is an example of the belt used in the present invention, moves on a slide plate 78 (corresponding to a cross section taken along line BB in FIG. 11A). FIG. 14 is a cross-sectional view showing the engagement state between the belt 70 ′ according to the present invention and the driving roller 73 ′ according to the present invention (the cross-sectional view taken along the line CC in FIG. 11A). (Corresponding figure).

In the endless belt according to the present invention indicated by reference numeral 70 'in the figure, a concave portion 70'a and a convex portion 70'b are provided on the back surface facing the sliding plate 78.

Since the convex portion 70 ′ b is in contact with the sliding plate 78, it is subjected to a surface treatment to reduce a friction coefficient or is formed of a material having a small friction coefficient so that running resistance is sufficiently reduced. You. Specifically, for example, the surface is coated with a fluororesin, a lubricant is applied to the canvas forming the surface, or the canvas itself is formed of a cloth of slippery material such as polyester. It is not limited to.

On the other hand, the concave portion 70'a is formed of a material having a large frictional coefficient or a material having a large frictional coefficient so that the driving roller 73 'can sufficiently drive. . Specifically, adhesive paint is applied to the canvas surface, synthetic rubber or the like is coated on the surface, or the belt body is formed of synthetic rubber or the like, and the formed surface is used. It is similar to the above without limitation.

The sliding plate 78 is provided with rising pieces 78a on both sides to prevent meandering of the belt 70 '.

On the outer circumference of the driving roller 7 3 ′, a convex portion 7 3 ′ a and a concave portion 7 3 ′ b that are in contact with the concave portion 70 ′ a of the belt 70 ′ are strongly provided, and the convex portion 7 3 ′ a and the concave portion 7 3 ′ The depth of b is adjusted such that a gap 90 is formed between the belt 70 'and the convex portion 70'b when the belt 70' is driven by the driving roller 73 '. The convex portion 73'a of the driving roller 73 'is formed of a material which is subjected to a surface treatment for increasing a friction coefficient so as to obtain a sufficient driving force, or a material having a large friction coefficient L or a material. . Specifically, as in the case of the belt 70 ', an adhesive paint or the like may be applied to the surface, or the roller body may be formed of synthetic rubber or the like.

With such a configuration, the contact with the sliding plate 78 is a part of the back surface of the belt 70 ', which has a very small friction loss, so that the running resistance can be suppressed as low as possible, and at the time of being driven, the friction is reduced. Since only the convex portion 73'a of the large driving roller 73 'and the concave portion 70'a on the back surface of the belt 70' come into contact with each other, a sufficiently large driving force can be obtained.

As described above, according to the present invention, it is possible to obtain an ideal moving sidewalk driving device in which the frictional resistance on the sliding plate is reduced and the frictional driving force in the drive roller is increased. Also, the meandering of the belt itself can be prevented more appropriately. Industrial applicability

The moving walkway of the present invention is capable of transporting passengers quickly and safely, and is particularly suitable for installation in a wide area such as an airport or a large shopping center.o
