Description

  The present invention relates to a passenger conveyor device, and in particular, by controlling a gap between a driving roller provided on a step of the passenger conveyor and a driving rail that receives the driving roller, a gap between the step of the passenger conveyor and the skirt guard is provided. The present invention relates to a passenger conveyor device to be adjusted.

  Passenger conveyors refer to devices that transport passengers such as escalators and moving walkways. In FIG. 3, the structure in the case of the escalator 20 as a general passenger conveyor apparatus 30 is shown. The passenger of the escalator 20 moves on the step 2 having the step surface 3 and the riser surface 4. The step 2 travels while being supported by a pair of driving rollers 5 as front wheels and a pair of follower rollers 7 as rear wheels. The two drive rollers 5 are connected via a step shaft 9 and are driven by a step chain 10 to travel on the drive rail 6. The step chain 10 is driven by a drive unit (not shown) provided on the escalator 20 and a drive chain (not shown). The two follower rollers 7 run on an L-shaped follower rail 8 '.

  FIG. 4 shows a view of the escalator 20 as viewed from above. A skirt guard 21 is provided inside the handrail 17 of the escalator 20 to protect passengers. If the gap (d) between the step surface 3 of the step 2 and the skirt guard 21 is too large, an object will be caught or dropped in the gap (d), so that it is within 5 mm as one inspection standard (JIS A-4302). The left and right are within 10 mm. The escalator manufacturer's in-house standards set even stricter standards than this inspection standard. If the gap (d) is too small, the step surface 3 and the skirt guard 21 come into contact with each other due to the lateral movement of the passenger riding on the step 2 or the lateral play of the step 2, and the surface of the skirt guard 21 In other words, a stagnation occurs, a squeaking noise is generated, or a drive device of the escalator 20 is adversely affected. Therefore, this gap (d) must be secured to some extent.

In FIG. 5, the play of the horizontal direction which the step 2 of the conventional passenger conveyor apparatus 30 has is shown. Moreover, the partial detail of each part of the passenger conveyor apparatus 30 shown in FIG. 5 is shown in FIG. 6A is a partial detail of FIG. 5A, FIG. 6B is a partial detail of FIG. 5B, and FIG. 6C is a schematic view of (c) of FIG. ) Is a partial detail. The lateral play of the step 2 described above is the gap between the drive rail 6 of the U-shaped groove and the sliding plates 12 attached to both sides of the drive roller 5 moving in the groove, as shown in FIG. (D ₁ ), the gap (d ₂ ) between the step link bush 11 that receives the step link 10 and the split retaining ring 18a shown in FIG. 6B, and the step base 19 and the divided retaining ring shown in FIG. 6C. It is determined by the gap (d ₃ ) of 18b. On the other hand, the conventional follower roller 7 shown in FIG. 5 is placed on an L-shaped follower rail 8 '. The follower rail 8 ′ does not have a function of regulating the travel position of the follower roller 7.

JP 2001-316066 A

  In the conventional escalator, the adjustment of the gap between the step and the skirt guard is achieved by regulating the gap between the step drive roller and the U-shaped drive rail that receives the drive roller, thereby allowing the step to go straight. . However, since the steps of the passenger conveyor device have lateral play as described above, there is a problem that maintenance is required to maintain the adjustment of the gap between the steps and the skirt guard.

  In other words, when wear due to parts rubbing against each other progresses in each gap, the play in the lateral direction of the step increases, making it difficult to maintain the above-described reference value. Further, since a manufacturing error of individual parts constituting the step is added, it becomes more difficult to secure a desired gap between the step and the skirt guard.

  On the other hand, by reducing each gap, the lateral play of the step can be reduced. For example, abnormal noise due to sliding of each component, early wear of each component, or increased burden on the bearing of the drive roller There is a risk of problems such as broken bearings.

  An object of the present application is to provide a passenger conveyor device that solves such problems and facilitates management of the gap between the step and the skirt guard while ensuring lateral play of the step.

  In order to achieve the above object, a passenger conveyor apparatus according to the present invention regulates a gap between a driving roller provided on a step of the passenger conveyor and a driving rail that receives the driving roller, so that the step of the passenger conveyor and the skirt guard In the passenger conveyor device that adjusts the gap between the groove and the guide rail provided at the end of the groove portion for receiving the follower roller provided on the step, and the guide portion that regulates the lateral movement of the follower roller, It is characterized by managing the gap between the step and the skirt guard.

  With the above-described configuration, the passenger conveyor device includes a groove portion that receives the tracking roller and a guide portion that is provided at an end of the groove portion and regulates the lateral movement of the tracking roller with respect to the tracking rail on which the tracking roller that supports the step travels. Thus, the straightness of the step can be achieved. That is, by ensuring the straightness of the follower roller, the gap between the step and the skirt guard can be easily managed without being affected by the play in the lateral direction of the step.

  In the passenger conveyor device, the lateral width of the groove portion is substantially the same as the lateral width of the follower roller, and it is preferable that the guide portion provided at the end portion of the groove portion rises from the end portion of the groove portion. Accordingly, if the straightness of the tracking rail is adjusted when the passenger conveyor is installed, the straightness of the step can be secured by the tracking roller that moves according to the tracking rail.

  In the passenger conveyor device, it is preferable that the guide portion bulges in a convex shape so that the follower roller can be ridden and stands from the end of the groove portion. Thus, even if the step is forcibly moved in the horizontal direction due to the lateral movement of the passenger on the step, the follower roller rides on the guide portion, so that the step itself is not restrained.

  Moreover, as for a passenger conveyor apparatus, it is preferable that the one side of a pair of tracking rail equips the both ends of a groove part with a guide part. Thereby, at the time of installation of a passenger conveyor, a desired clearance between the step and the skirt guard can be ensured by managing only the installation accuracy of the one-side tracking rail.

  Moreover, as for a passenger conveyor apparatus, it is preferable that both following rails equip the outer edge part of each groove part with a guide part. Moreover, it is preferable that both following rails are provided with a guide part at the inner end of each groove part. As a result, by managing the installation accuracy of the most recent tracking rail for managing the gap between the step and the skirt guard, it is possible to secure a desired gap between the gaps on both sides of the step and the skirt guard.

  Further, in the passenger conveyor device, it is preferable that holes are formed in the groove portion of the tracking rail at a predetermined pitch in the length direction. Thereby, dust and falling objects accumulated in the groove portion sandwiched between the guide portions can be naturally excluded.

  As described above, according to the passenger conveyor device of the present invention, it is possible to provide a passenger conveyor device that facilitates the management of the gap between the step and the skirt guard while ensuring lateral play of the step. It becomes.

  Hereinafter, an embodiment of a passenger conveyor device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic configuration of one embodiment of a passenger conveyor device. FIG. 2 shows a plurality of embodiments of the configuration of the tracking rail of FIG. The passenger conveyor device 1 of the escalator 20 includes a pair of driving rollers 5 provided on the steps 2, a driving rail 6 that receives the driving rollers 5, a step shaft 9 that connects the driving rails 6, a pair of tracking rollers 7, and a tracking roller 7. It is comprised from the following rails 8a and 8b which receive.

  A pair of sliding plates 12 is provided between the driving roller 5 and the U-shaped driving rail 6 on which the driving roller 5 travels. The drive roller 5 is driven by a step link (or step chain) 10 connected to a drive unit (not shown) provided on the escalator 20. For this reason, a pair of split ring stoppers 18a are attached to the step shaft 9 connected to the drive roller 5, and a step link bush 11 that receives the step link 10 is inserted between the split ring stoppers 18a. Further, the step 2 is connected to a step base 19. A pair of split ring stoppers 18b is attached to the step shaft 9, and a step cap 19 is inserted between the split ring stoppers 18b. Further, the follow-up roller 7 is fixed to the step 2 via the support member 24.

Accordingly, as shown in FIG. 6A, the play in the lateral direction of the step 2 is caused between the driving rail 6 of the U-shaped groove and the sliding plates 12 attached to both sides of the driving roller 5 moving in the groove. As shown in FIG. 6B, the gap (d ₁ ), the gap (d ₂ ) between the step link bush 11 and the divided retaining ring 18a, and as shown in FIG. 6C, the step base 19 and the divided retaining ring. It is determined by the gap (d ₃ ) of 18b. That is, the pair of driving rollers 5 and the step shaft 9 connecting the driving rollers 5 are provided with gaps (d1, d2, d3) with respect to the driving rail 6, the step link 10, and the step 2 in the lateral direction. Have play. This play copes with wear of parts caused by rubbing against each other in each gap. Further, the movement for following the movement in the lateral direction of the passenger on the step 2 or allowing the object to be extracted when an object is caught in the gap (d) between the step 2 and the skirt guard 21 is allowed.

  The pair of follower rails 8 according to the present invention shown in FIGS. 1 and 2 (a) is a combination of a follower rail 8a on the left side and a follower rail 8b on the right side in FIGS. The tracking rail 8a includes a groove portion 13 that receives the tracking roller 7 and guide portions 14 that are provided at both ends of the groove portion 13 and restrict lateral movement of the tracking roller 7. On the other hand, the follower rail 8b has a conventional L-shaped shape and does not restrict the lateral movement of the follower roller 7. The lateral width of the groove 13 of the follower rail 8a is substantially the same as the lateral width of the follower roller 7. Accordingly, the follower roller 7 and the follower rail 8a have no lateral play. Further, since the follower roller 7 is fixed to the step 2 via the support member 24, the follower roller 7 travels along the groove 13 of the follower rail 8a in principle.

  The guide portions 14 provided at both ends of the groove portion 13 of the tracking rail 8a stand up from the end portion of the groove portion 13 and bulge in a convex shape so as to be able to ride on the tracking roller 7, and are connected to the end portion of the groove portion 13. As described above, the follower roller 7 travels along the groove portion 13 of the follower rail 8a. However, if the guide portion 14 restricts the lateral movement of the follower roller 7, a problem occurs. This is because, for example, lateral movement occurs by passengers riding on the step 2. Moreover, it is because it must be extracted when an object is caught in the gap (d) between the step 2 and the skirt guard 21. Due to the shape of the guide portion 14 of the follower rail 8a, the follower roller 7 to which a lateral movement is applied from the step 2 temporarily rides on the convex portion of the guide portion 14. Then, when the lateral movement is reduced, the groove 13 is restored by the inclination of the convexly bulging portion.

  Due to the configuration of the follower rail 8, the follower roller 7 of the step 2 moves according to the straightness of the groove 13 of the follower rail 8a, and the gap (d) between the step 2 and the skirt guard 21 corresponds to the groove 13 of the follower rail 8a. Depends on straightness. Further, the lateral movement applied from the step 2 is absorbed by the guide portion 14 of the tracking rail 8a. On the other hand, a gap (d1, d2, d3) with respect to the drive rail 6, the step link 10, and the step 2 is ensured for the pair of drive rollers 5 and the step shaft 9 connecting the drive rollers 5.

  In the embodiment of the follower rail 8 shown in FIGS. 1 and 2A, the follower rail 8a on one side includes guide portions 14 at both ends of the groove 13, while the follower rail 8b on the other side is a conventional follower rail. Like 8 ', it is L-shaped. The follower rail 8a and the follower rail 8b may be reversed left and right. In this way, by performing the rectilinearity of the tracking roller 7 by only one of the tracking rails 8a, only the installation accuracy of the tracking rail 8a on one side needs to be managed when the escalator 20 is installed. Thereby, it becomes easy to secure a desired gap (d) between the step 2 and the skirt guard 21.

  In the embodiment shown in FIG. 2B, both follower rails 8 c include guide portions 14 at the outer end portions of the respective groove portions 13. Further, in the embodiment shown in FIG. 2C, both follower rails 8 d include guide portions 14 at the inner end portions of the respective groove portions 13. Regarding the management of the gap (d) between the step 2 and the skirt guard 21, the desired gap (d) can be ensured by managing the installation accuracy of the nearest following rails 8c, 8d. In addition, the left and right follower rails 8c and 8d can share the stable on the step 2 depending on the direction of the ride.

  FIG. 7 shows a cross section of the hole 22 provided in the tracking rail 8a. Holes 22 are formed in the groove 13 of the tracking rail 8a at a predetermined pitch in the length direction. Thereby, compared with the conventional L-shaped following rail 8 ', dust and falling objects accumulated in the concave groove portions 13 formed by the guide portions 14 on both sides can be discharged naturally.

  With the above configuration, the passenger conveyor device 1 is provided on the tracking rails 8a, 8b, and 8c on which the tracking roller 7 that supports the step 2 travels, the groove 13 that receives the tracking roller 7, and the tracking roller that is provided at the end of the groove 13 By providing the guide portion 14 that restricts the lateral movement of the step 7, it is possible to manage the gap (d) between the step 2 and the skirt guard 21 while securing the lateral play of the step 2.
