Description

  The present invention relates to a moving handrail guide device for passenger conveyors such as escalators.

  2. Description of the Related Art Conventionally, in a moving handrail guide device for a passenger conveyor, a synthetic resin guide body that fits inside the moving handrail and regulates the lateral movement of the moving handrail is rotatably provided (for example, Patent Documents). 1). This moving handrail guide device has a configuration in which the rotating portion of the guide body is brought into contact with either one of the inner side surfaces of the moving handrail to restrict the lateral movement of the moving handrail. Provided at both ends. Then, when the ear part of the moving handrail and the driving roller are in contact, the guide body is rotated in the direction of the ear part where the guide body and the driving roller are in contact, and the guide body moves laterally by pressing the moving handrail. By acting, the gap dimension between the driving roller and the moving handrail can be adjusted.

JP 2001-146378 A

  In the conventional handrail guide device for passenger conveyors, when the handrail driving device is composed of a plurality of driving rollers, the position of each driving roller is driven by the manufacturing error of each driving roller section and the driving force during operation. Since each drive roller is not in a straight line because it is displaced in the axial direction of the roller or tilted with respect to the moving direction of the moving handrail, and the flow of the moving handrail changes depending on the operating direction of the moving handrail, the gap size is Change. Therefore, there is a problem that even if the gap between the ear part of the moving handrail and the driving roller can be secured by a certain driving roller, it cannot be secured by another driving roller. The adjustment becomes more difficult as the number of driving rollers increases. As in the prior art, it is not easy to secure the gap between each drive roller and the moving handrail ear portion only by restricting the lateral movement of the moving handrail with the guide bodies provided at both ends of the handrail driving device. It was difficult to adjust so that the plurality of driving rollers were not in contact with each other.

  The present invention has been made to solve the above-described problems. A handrail guide device corresponding to a displacement (posture) displacement of a driving roller of a moving handrail is provided to adjust a gap size in a handrail driving device section. Provided is a moving handrail guide device for a passenger conveyor which is unnecessary and prevents the generation of abnormal noise due to contact and the breakage of the driving roller and the moving handrail by easily securing a gap between the moving handrail and the handrail driving roller. It is.

  The moving handrail guide device for a passenger conveyor according to the present invention includes a handrail guide device that is provided in a peripheral portion of the handrail driving device and regulates the lateral movement of the moving handrail. A cage provided on the shaft of the drive roller of the apparatus, and a guide body provided in the cage and usually disposed in an opening between the ear portions of the moving handrail so as not to contact the handrail ear portion When the gap between the drive roller and the handrail ear becomes narrow, the guide body comes into contact with the handrail ear portion of the opening of the handrail before the two contact with each other, and the lateral movement of the handrail Is to regulate.

  According to the present invention, it is not necessary to finely adjust the gap size in the handrail drive unit, and the gap between the moving handrail and the handrail drive roller can be easily secured. And generation | occurrence | production of the abnormal sound by a contact and damage to a drive roller and a moving handrail can be prevented.

Reference numeral 8 denotes a lower sprocket provided in a lower floor portion in the main frame 1, and 9 denotes a handrail drive device provided in an upper part in the main frame 1. A driving force transmission chain 10 is wound between the handrail driving device 9 and the driving sprocket 4, and the driving force is transmitted to the handrail driving device 9 by the driving force transmission chain 10.

  The handrail driving device 9 is configured as shown in FIGS. 7 is a moving handrail, 7a is an ear of the moving handrail, 11 is a plurality of (for example, four) driving rollers, and enters from the opening between the ears 7a of the moving handrail 7 and contacts the inner side of the back surface of the moving handrail 7 Has been placed. A handrail drive chain 12 is engaged with the shaft 13 of the drive roller 11 to transmit a driving force, and rotates the drive roller 11. Reference numeral 14 denotes a plurality of (for example, four) pressing rollers, which press the surface side of the moving handrail 7 with the spring 16 engaged with the connecting member 15 facing the driving roller 11 with the moving handrail 7 therebetween. Yes. The gap between both side surfaces of the drive roller 11 and the ear portion 7a of the moving handrail 7 is about several millimeters.

  A handrail guide device 17 is provided on the shaft 13 of the drive roller 11. The handrail guide device 17 has a central portion fixed to the shaft 13 of the driving roller 11 and both arm portions extending to the outside of the outer diameter of the driving roller 11 along the handrail traveling direction. A retainer 17a having a downward L-shaped holding portion formed thereon, a shaft portion 17b fixed at the center of the horizontal portion of the L-shaped holding portion of the retainer 17a, and a shaft portion 17b rotatably supported by the shaft portion 17b. And a guide body 17c made of a circular rotating body disposed in an opening between the ear portions 7a of the handrail 7. As shown in FIG. 4, the guide body 17 c made of this circular rotating body is smaller than the opening size between the ear portions 7 a of the moving handrail 7 and larger than the width size (distance between both side surfaces) of the driving roller 11. It has a diameter and is usually arranged so as not to contact the handrail ear portion 7a.

  Here, as shown in FIG. 6, some positions (postures) of the plurality of drive rollers 11 and the shaft 13 are shifted from the normal state toward the shaft 13, or in the traveling direction of the moving handrail 7. When the gap between the driving roller 11 and the handrail ear portion 7a is narrowed due to inclination, the guide body 17c composed of a circular rotating body of the handrail guide device 17 fixed to the shaft 13 is moved before the contact between them. 7 is in contact with the ear portion 7a of the opening 7 to restrict the lateral movement of the moving handrail 7 to prevent the drive roller 11 from contacting the handrail ear portion 7a.

  As described above, according to the first embodiment, it is not necessary to finely adjust the gap size in 9 parts of the handrail driving device, and the gap between the moving handrail and the handrail driving roller can be easily secured. And generation | occurrence | production of the abnormal sound by a contact and damage to a drive roller and a moving handrail can be prevented. In addition, if the guide body 17c is made of a low friction synthetic resin, no abnormal sound is generated even if it is in contact with the handrail ear.

Embodiment 2. FIG.
FIG. 7 is a plan view corresponding to FIG. 5 showing a moving handrail guide device for a passenger conveyor according to Embodiment 2 of the present invention.
In the first embodiment, the guide body 17c of the handrail guide device 17 is configured by a circular rotating body. However, in the second embodiment, the guide body 17c of the handrail guide device 17 is configured by a fixed rectangular body. It is what.
Also in the second embodiment, as shown in FIG. 7, the guide body 17c made of a fixed rectangular body is smaller than the opening size between the ear portions 7a of the moving handrail 7 and the width size of the driving roller 11 ( The distance is larger than the distance between both side surfaces, and is usually not in contact with the handrail ear portion 7a.
