Description

Description Field of the Invention The present invention relates to an improvement of an entrance / exit device for a belt-type moving sidewalk, particularly a moving sidewalk using a flat belt. Background art

On a conventional rubber belt-type moving sidewalk, the moving speed was usually as low as 30 m or 40 m per minute. In addition, a groove is provided on the circulation belt, which engages with the comb teeth (comb) at the entrance and exit. The belt is generally thick and has a large turning radius. Was also very thick.

Therefore, recently, an accelerating moving sidewalk or a constant-speed moving sidewalk as shown in FIGS. 2 (a) to 2 (c) has been proposed (for example, see Japanese Patent Application Laid-Open Publication No. Hei 9-918926). The moving walkway shown in Fig. 2 (a) is a series of circulating belts 1, 2, 3, 4, 5 that can be driven at different speeds, and the speed of these belts is Normally, it is set to be minimum at end 1, accelerated sequentially, and maximized in center 5. The same applies to the moving sidewalks in Figs. 2 (b) and (c), in which the central circulation belt runs at a higher speed than the belts at both ends. However, each of these belts can be driven at the same speed throughout the moving walkway. Handrails are provided on both sides of these belts as before.

In these moving walkways, at least the circulating belt 1 facing the plate 6 located at the entrance / exit shall use a circulating belt with a thin, flat grooved flat structure. (1) The guide roller at one end has a small diameter low By reducing the turning radius using a staircase, the overall thickness of the moving sidewalk is reduced, so that it can be installed directly on the floor.

In such a belt-type moving sidewalk, it is extremely important for passenger safety to prevent passengers' shoes, clothes, luggage, etc. from being pinched by the entrance / exit system at the end of the belt. For example, the applicant has disclosed the apparatus shown in FIG.

-It is disclosed in Japanese Patent Publication No.

Fig. 3 is a view taken in the direction of arrows A-A in Fig. 2. In the device shown in this figure, the safety piece 8 moves vertically between the end of the circulation belt 1 and the plate 6. When an object is caught in the gap between the circulating belt 1 and the safety piece 8 or the pre--6, the safety piece 8 is pushed down by the object, and the switch is thereby turned off. (Not shown) operates and the circulation bell

Stop one.

However, in such an entrance / exit device, as described above, when an object is caught in the gap between the circulation belt 1 and the safety piece 8, the switch operates to move <the sidewalk, but the circulation bell is stopped. There was a problem that the object stayed retracted between G1 and the safety piece 8 or Pre-6.

The present invention has been made in view of the above points, and has as its object to provide a more secure pedestrian entrance / exit device. Disclosure of the invention

The pedestal type moving sidewalk entrance / exit device of the present invention is a moving sidewalk entrance / exit device in which passengers are transported by a circulation belt, and has a comb at a position facing an end of the circulation belt. In addition, a roller is provided rotatably below the comb so as to substantially close the gap between the end of the circulation belt and the comb. A plurality of notches are provided at the end of the comb facing the circulation belt, and it is preferable that a part of the roller protrudes upward from the notches. New

As the above-mentioned roller, a grooved rotating body having a plurality of grooves provided in the circumferential direction is suitably used. Such a roller forms a groove on the outer peripheral surface of a cylindrical body or a cylindrical body, or has a plurality of grooves. It is obtained by fixing two annular bodies to a common shaft.

It is preferable that the above roller is rotated in the same direction as the circulation direction of the circulation belt. By rotating the rollers, passengers' shoes and the like can be pushed up onto the comb. In order to rotate the rollers, an independent driving device may be used, or the rollers may be linked to a circulation belt. The rotation speed of the roller is preferably higher than the moving speed of the circulation belt. In addition, the outer peripheral surface of the roller is subjected to knurling or forming a rubber layer to increase the coefficient of friction to make it easier for foreign substances to be pushed up. I can do it. If a foreign object is caught between the roller and the circulation belt, release the brake of the driving device so that the roller can rotate freely, or It is preferable to drive the roller so as to rotate in a direction to discharge the foreign matter.

The cutouts of the comb can be arranged, for example, with a predetermined width and pitch. Further, by bringing the tip of the comb close to just before contacting the circulating pelt, it is possible to further improve safety.

Regarding the positional relationship between the circulation belt and the comb, it is preferable to arrange the tip of the comb at a lower level than the running surface of the circulation belt. Further, in order to make the traveling of vehicles easier, the traveling surface of the circulation belt, the upper end of the comb, and the upper end of the mouthpiece may be arranged on substantially the same horizontal line.

In the drawings, those with the J-code in Fig. 2 or Fig. 3 indicate the same parts or members.

As shown in these figures, the pelt-type motion <the sidewalk □ device of the present embodiment almost closes the gap between the end of the circulating belt 1 and the tip of the comb 10 facing the end. In this way, the D-fighter works to help the passengers move smoothly.

1 1 is provided rotatably below the comb 10 0

Com 10 is detachably attached to Com Plate 20 and has a circulation bell h 1 They are arranged at opposing positions. At the end of the comb 10 facing the circulation belt 1, a plurality of notches 10a are provided with a predetermined width and pitch, as shown in FIG. Regarding the width d and the pitch p of the notch 10a of the comb 10a, for example, even if the passenger is wearing high heels, the heel should not fall into or fall into the notch 10a. It is set to the appropriate dimensions. For example, the width d is about 5 mm, and the pitch p is about 8 mm. The tip 10b of the comb 10 is located at a lower level than the running surface of the circulation belt 1 as shown in FIG.

The roller 11 is, as shown in FIG. 5 (A), a grooved rotary member having a plurality of grooves provided in a circumferential direction, and has a plurality of grooves 1 la formed on an outer peripheral surface of a cylindrical member. The width and pitch of the grooves 11a are determined so that the protrusions (clear portions) 11b between the grooves match the notches 10a of the comb 10. The outer peripheral surface 11 c of the roller is knurled. As shown in Fig. 6, the roller 11 is disposed near the tip 10b of the comb 10 so that a part of the clear portion 11b projects upward from the notch 10a. . In the device having the above configuration, the circulating belt 1 is driven by a driving device (geared motor) 31 via a belt driving pulley 30 as shown in FIG. 4, and the roller 11 is driven by another driving device. Driven by the device (gear, gear, etc.) 32, they circulate and rotate in the directions indicated by the arrows in FIGS. 1 and 4, respectively. Roller 11 is preferably rotated at a peripheral speed equal to or higher than the traveling speed of circulation belt 1. When the roller 11 rotates at a peripheral speed higher than the traveling speed of the circulating belt 1, the circulating belt 1 tries to push it out through the mouth rather than trying to draw an object into the recess. The effect is greater. With the above configuration, the footwear of the passenger riding on the circulating belt 1 becomes less likely to be caught in the concave portion of the end turning portion of the circulating belt 1, and even if the passenger circulates the foot. Do not neglect to move from top of Belt 1 to Com 10 side In spite of this, the passenger's footwear is picked up by the rotation of the rollers 11 and then sent forward, and the passenger's footwear is turned at the end turning part of the circulation belt 1. The danger of being caught in the concave portion is reliably avoided. In particular, as shown in Fig. 6, a part of the roller 11 protrudes partially from the notch 10a of the comb 10 to transfer from the circulation belt 1 to the comb 10. The resmoothing is smoother and the safety is further improved.

Regarding the size of the guide roller 7 and the roller 11, it is preferable that the guide roller 7 and the roller 11 have a smaller diameter in the recess formed by these two rollers, from the viewpoint of the ease of transfer of footwear and other objects by passengers. Is set to about 30 mm or less.

As described above, according to the entrance / exit device of the present invention, it is extremely rare that an accident that a passenger's footwear or the like gets caught in the concave portion of the end turning portion of the circulation belt 1 is extremely rare. In the event of a serious accident, the roller 11 should be configured so that the brake is released and can be rotated, or the roller 11 can rotate in the direction to discharge the sandwiched object. Is more preferable.

More specifically, for example, as shown in FIG. 6, a photoelectric sensor 40 is provided between the circulation belt 1 and the comb 10 to stop a moving sidewalk when a foreign object is detected as being caught, Release the electromagnetic brakes (not shown) of the circulating belt 1 and the drive devices 31 and 32 of the rollers 1 and 1 so that the trapped foreign matter can be pulled out manually. The light beam of the photoelectric sensor 40 passes below the trajectory of the object thrown from the circulating belt 1 and is set so as not to work normally. After pulling out the foreign object, operate the buzzer key switch (not shown) on the operation panel to sound the buzzer and set the electromagnetic brake. Next, turn the up / down key switch on the operation panel in the driving direction to release the electromagnetic brake, and then start the moving sidewalk.

Or, when a foreign object is detected, stop the moving sidewalk, A key switch (not shown) provided near the operation panel is operated to release the circulating belt 1 and the electromagnetic brakes of the driving devices 31 and 32 of the rollers 11 and the circulating bell in the direction to remove foreign matter. Drives the roller 1 and the roller 11 to discharge the foreign matter between them. Then, operate the buzzer key switch on the operation panel to sound the beeper and set the electromagnetic brake. In addition, turn the up / down key switch on the operation panel in the driving direction and release the electromagnetic brake to activate the moving sidewalk.

In the above embodiment, a roller formed by forming a groove in a cylindrical member or a cylindrical member and having a groove 1 la and a clear portion 11 b integrally formed is used. Roller 11 has a groove 11a and a clear part 1 lb by fixing a ring-shaped member to shaft 11d by the number of notches 10a in comb 10. It is also possible to adopt a configuration provided with.

Also, instead of subjecting the outer peripheral surface 11 c of the roller to the knurling as described above, a rubber layer lie may be formed as in the roller 11 shown in FIG. 5 (B). . The method for forming the rubber layer is not particularly limited, and the rubber may be vulcanized on the peripheral surface of the roller using a mold, or the rubber previously formed to an appropriate size and thickness may be bonded with an adhesive. It may be adhered.

In addition, the driving method of the roller 11 is not rotated by a driving device different from the driving device of the circulating belt as described above, but as shown in FIG. It can also be linked. Reference numeral 12 denotes a rotating body such as a pulley provided at one end of the shaft 1 Id, and a bell is provided between the rotating body 13 and the rotating body 13 provided on the shaft 7 a of the guide roller 7 of the circulating belt 1. A transmission body 14 like a wing is wound. Therefore, when the circulation belt 1 circulates in the direction of the arrow, the rotating body 13 rotates clockwise, and the roller 11 rotates through the transmission body 14, the rotating body 12 and the shaft 11d. It rotates in such a direction that the passengers on the circulation belt 1 can move smoothly on the Com 10 and Com Plate 20. It is more desirable that the diameter of each of the rotating body 12 and the rotating body 13 reach such that the peripheral velocity of the roller 11 is equal to or higher than the circulation velocity of the circulation belt 1. In the case of this configuration, if a foreign object is trapped, the circulation belt 1 and the roller 11 cannot both be rotated in the direction in which the foreign object is discharged, but the number of driving devices is reduced. There is an advantage that the entrance / exit device of the present invention can be obtained at lower cost.

As another embodiment of the present invention, a moving sidewalk having a configuration shown in FIG. 9 can be considered as a configuration particularly suitable for a passenger using a wheelchair or a passenger pulling a vehicle such as a beaker.

FIG. 9 is a side view corresponding to FIG. 6, in which the same reference numerals as in FIGS. 1 to 8 denote the same components. In this example, in particular, the running surface of the circulation belt 1 and the upper ends of the rollers 11, the combs 60, and the comb plates 70 are arranged on the same horizontal line.

With such a configuration, almost no resistance is felt when passengers of vehicles get on and off, so the use of moving walkways is more comfortable. Naturally, there is no problem for ordinary passengers. In this embodiment, the configuration of the roller 11 can be the same as that of the above-described embodiment.

To further improve safety, change the shape of the comb as shown in Figs. 10 (A) and (B) and move the tip of the comb 61 closer to the circulating belt 1. It is also possible to make the gap with the circulation belt 1 hardly occur. This is the same in the first embodiment described above. As described above, according to the present invention, since the rollers provided under the com-plate work to prevent the objects such as the shoes of the passengers from being pinched, the user can move the sidewalk more safely. Can be used. Industrial applicability
