Description

  The present invention relates to a passenger conveyor including an escalator and an electric road, and more particularly to a configuration of a mechanism for adjusting the tension of a moving handrail and guiding traveling.

  The passenger conveyor is provided with a mechanism for adjusting the tension of the moving handrail and guiding the traveling. FIG. 10 shows a configuration example of such a mechanism in a conventional passenger conveyor. A push guide support portion 6 is attached to a support structure of a passenger conveyor (not shown) at a turn-back position between the inclined straight portion 3a and the lower horizontal portion 3b of the moving handrail 3 of the passenger conveyor. In the push guide support portion 6, the moving handrail 3 is configured in a state in which the arcuate push guide 5, which is an arcuate resin member, is displaceable in a direction (vertical direction in the figure) perpendicular to the plane portion of the moving handrail 3. It is supported so as to press the inner side of the circumference. By the pressing force of the arcuate push guide 5, the slack of the moving handrail 3 is removed, and the moving handrail 3 maintains an appropriate tension. When the handrail 3 tries to meander, the arcuate push guide 5 guides the handrail 3 in the width direction to prevent meandering.

  Before and after the arcuate push guide 5 and the push guide support portion 6, the guide roller 4 is attached to a support structure of a passenger conveyor (not shown) and abuts on the outer side of the circumference formed by the moving handrail 3 so that the moving handrail 3 travels. To guide you.

  In addition, as a travel guide mechanism different from that shown in FIG. 10, there is also disclosed a guide roller disposed near both ends of a support frame of a moving handrail (see Patent Document 1). FIG. 11 shows a configuration example of such a travel guide mechanism. A handrail (moving handrail) 23 is supported on a guide frame (supporting frame for moving handrail) 21 in which both end portions 21a and 21b spread like a bowl. Both end portions in the width direction of the handrail 23 are detachment preventing portions 23 a and 23 b that are folded back in an ear shape in order to prevent detachment from both end portions 21 a and 21 b of the guide frame 21. The guide roller (guide roller) 22 is rotatably supported in the middle of both end portions 21 a and 21 b of the guide frame 21 (that is, inside the disengagement preventing portions 23 a and 23 b of the hand rail 23), and comes into contact with the hand rail 23. Guide the run.

JP 2006-273531 A

  In the configuration shown in FIG. 10, when the passenger conveyor is driven, the arcuate push guide 5 pressing the moving handrail 3 is in sliding contact with the moving handrail 3, so that a large frictional force is generated and the running resistance of the moving handrail 3 is increased. It became a factor to increase. Further, in order for the arcuate push guide 5 to guide the moving handrail 3 in the width direction to prevent meandering travel, the arcuate push guide 5 needs to have a wide width. The wide width is substantially the same as the width of the moving handrail 3, but when the width is not less than the width of the moving handrail 3, the portions folded back in the shape of ears at both ends in the width direction of the moving handrail 3. 11 (a portion corresponding to the detachment preventing portions 23 a and 23 b in FIG. 11), the width is narrower by several millimeters than the moving handrail 3. For this reason, it was difficult to reduce the size of the parts.

  On the other hand, in the configuration disclosed in Patent Document 1 as shown in FIG. 11, there is a concern that the meandering traveling of the handrail 23 cannot be prevented. This is because the tip ends of both end portions 21a and 21b of the guide frame 21 are arranged outside the guide roller 22, so that the handrail 23 is displaced from the guide roller 22 when the handrail 23 is displaced in the left-right direction in the drawing. Since the tips of both end portions 21a and 21b come into contact with the disengagement preventing portions 23a and 23b first, there is a concern that the function of the guide roller 22 to guide the handrail 23 in the width direction is impaired. Further, if the traveling continues in such a state that the disengagement preventing portions 23a and 23b are in contact with the both end portions 21a and 21b, there is a concern that the handrail 23 may be damaged.

  In view of the above-mentioned points, the present invention provides a passenger conveyor that can reduce the frictional force with a moving handrail, reduce the size of parts, and adjust the tension of the moving handrail and guide in the width direction. Objective.

  In the description of the following specification, portions of the moving handrail that are folded back in the shape of ears at both ends in the width direction (portions corresponding to the disengagement preventing portions 23a and 23b in FIG. 11) are referred to as “ear portions”. The remaining flat part in the width direction (that is, the part that does not overlap the ear part) will be referred to as a “planar part”.

In order to solve the above-described problems and achieve the object of the present invention, a passenger conveyor according to the present invention includes a support structure installed in a building, and a plurality of endlessly connected units that circulate and move within the support structure. , A balustrade erected along the direction of movement of the treads, and ears folded at both ends in the width direction, and the remaining part in the width direction is a flat flat part The tension which presses the inner peripheral side of the plane part by the endless movement handrail which moves along the peripheral edge of the balustrade, and a plurality of rollers having a width smaller than the width of the plane part of the handrail An adjustment and travel guide unit . The plurality of rollers include a first roller, a second roller, and a third roller. The first roller, the second roller, and the third roller run so that the moving handrail does not meander more than a predetermined size by sandwiching the center of the moving handrail in the width direction in the plane portion of the moving handrail. The center position in the width direction of the roller is shifted from each other at the guiding position. The first roller, the third roller, and the second roller are arranged at an interval in the moving direction of the moving handrail. The first roller, the second roller, and the third roller are arranged at an interval in the width direction of the moving handrail. The first roller, the second roller, and the third roller are arranged in a positional relationship corresponding to the three vertices of the triangle. The travel guide unit has a guide receiver that supports a plurality of rollers so as to be rotatable in the moving direction of the moving handrail, and the guide receiver is arranged right above the center in the moving handrail width direction.

According to the passenger conveyor having the above-described configuration, when the passenger conveyor is driven, the roller pressing the moving handrail is not in sliding contact with the moving handrail but in rotational contact, so the frictional force with the moving handrail is reduced and the moving handrail is reduced. The tension can be adjusted and the width direction can be guided.
In addition, since a plurality of rollers having a width smaller than the width of the plane portion of the moving handrail is used, the component dimensions can be reduced, and the tension of the moving handrail can be adjusted and the width direction can be guided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following drawings, the same reference numerals are given to the same components as those shown in FIG.
[First embodiment]
FIG. 1 shows the overall configuration of a passenger conveyor according to a first embodiment of the present invention. This passenger conveyor is composed of the following parts.
-Passenger conveyor support structure 10 installed in a building not shown
A plurality of steps (treads) 7 connected in an endless manner that circulates in the passenger conveyor support structure 10 between the two upper and lower passenger conveyor landings 11.
-A balustrade 13 erected along the direction of movement of the tread 7
-Both end portions in the width direction are ears that are folded back in an ear shape, the remaining portion in the width direction is a flat flat portion, and an endless moving handrail that moves along the periphery of the balustrade 13 3
-Tension adjustment and travel guide 12 for adjusting the tension of the handrail 4 and guiding travel

  2 to 4 show the configuration of the tension adjustment and travel guide portion 12 of FIG. 1, FIG. 2 is a side view of the overall configuration, FIG. 3 is a side view of the main portion, and FIG. 4 is a top view of the main portion. It is. As shown in FIG. 2, the push guide support portion 6 is the passenger conveyor support structure 10 of FIG. 1 at the turn-back position between the inclined straight portion 3a and the lower horizontal portion 3b of the moving handrail 3 of the passenger conveyor shown in FIG. Is attached. As shown in FIGS. 2 and 3, the guide guide 2 that supports the three rollers 1 a to 1 c so as to be rotatable in the moving direction of the moving handrail 3 is perpendicular to the plane portion of the moving handrail 3. In a state displaceable in any direction (vertical direction in the figure), the rollers 1a to 1c are supported so as to press the inner side (inner peripheral side) of the circumference formed by the moving handrail 3.

  As shown in FIG. 4, the guide receiver 2 is supported by the push guide support portion 6 of FIG. 2 so as to be positioned directly above the center of the movable handrail 3 in the width direction. Each of the rollers 1a to 1c has a width h2 that is smaller than the width h1 of the flat portion 3d of the moving handrail 3 (the portion excluding the ear portions 3c at both ends in the width direction), and the flat portion 3d from the inner peripheral side. It is supported by the guide receiver 2 so as to be pressed. Among the rollers 1a to 1c, the rollers 1a and 1c and the roller 1b run so that the moving handrail 3 does not meander more than a predetermined size by sandwiching the center in the width direction (vertical direction in the figure) of the moving handrail 3 The center position in the width direction of the roller is shifted from each other at a position for guiding the roller. Here, it is desirable that the rollers 1a and 1c have the same center position in the width direction of the rollers. At this time, the width h2 is smaller than half of the width h1, and therefore, the moving handrail 3 is arranged at intervals in the moving direction (left-right direction in the figure). That is, the rollers 1 a to 1 c are alternately arranged (so-called staggered) on the left side and the right side of the center of the width direction of the moving handrail 3 along the moving direction of the moving handrail 3. By the pressing force of these rollers 1a to 1c, the slack of the moving handrail 3 is removed, and the moving handrail 3 maintains an appropriate tension. When the handrail 3 tries to meander, these rollers 1a to 1c guide the handrail 3 in the width direction to prevent meandering.

  As shown in FIG. 2, before and after the rollers 1a to 1c, the guide receiver 2, and the push guide support portion 6, the guide roller 4 is attached to the passenger conveyor support structure 10 of FIG. The traveling of the handrail 3 is guided by abutting on the outer peripheral side.

  According to the passenger conveyor according to the first embodiment, when the passenger conveyor is driven, the rollers 1a to 1c pressing the moving handrail 3 are in rotational contact with the moving handrail 3 instead of sliding, so the moving handrail. The tension of the handrail 3 can be adjusted and the guidance in the width direction can be performed by reducing the frictional force with the handrail 3. Further, since the frictional force with the moving handrail 3 is reduced, the deterioration of the moving handrail 3 can be delayed and the operating life of the moving handrail 3 can be extended. In addition, since the running resistance of the moving handrail 3 is reduced by reducing the frictional force, the driving force of a moving handrail driving device (not shown) for running the moving handrail 3 can be reduced, which is necessary for operating the passenger conveyor. Power consumption can be reduced.

  Further, since the rollers 1a to 1c having the width h2 smaller than the width h1 of the flat surface portion 3d of the moving handrail 3 are used, the component dimensions can be reduced, and the tension of the moving handrail 3 can be adjusted and guided in the width direction. it can.

  Further, even when a roller having a width h2 smaller than the width h1 is used as the roller disposed on the flat surface portion 3d, the width of the roller is set at a position for guiding the traveling so that the moving handrail 3 does not meander over a predetermined size. Since the direction center positions are shifted from each other, when the moving handrail 3 tries to meander, components other than the rollers 1a to 1c (for example, the original moving handrail such as the end portions 21a and 21b shown in FIG. 11). Since the parts that should not be brought into contact with the ears 3c of the moving handrail 3 are not in contact with the rollers 1a to 1c, the function of the rollers 1a to 1c guiding the moving handrail 3 in the width direction is impaired. There is nothing.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. Note that in the second embodiment, redundant description of the same components as those in the first embodiment will be omitted. In the second embodiment, the arrangement of the rollers 1a to 1c is different from that of the first embodiment. Other configurations are the same as those of the first embodiment.

  FIG. 5 shows the arrangement of the rollers 1a to 1c in the second embodiment of the present invention in the same manner as FIG. Among the rollers 1a to 1c, the rollers 1a and 1c and the roller 1b run so that the moving handrail 3 does not meander more than a predetermined size by sandwiching the center in the width direction (vertical direction in the figure) of the moving handrail 3 The center position in the width direction of the roller is shifted from each other at a position for guiding the roller. Further, the rollers 1 a and 1 c and the roller 1 b are arranged at an interval in the width direction of the moving handrail 3. The roller 1a and the roller 1b are arranged at the same position in the moving direction of the moving handrail 3 (left and right direction in the figure), but the rollers 1a and 1b and the roller 1c are spaced apart in the moving direction of the moving handrail 3. It is arranged with a gap. That is, the rollers 1a to 1c are arranged in a positional relationship corresponding to the three vertices of a right triangle.

  In the same manner as described for the passenger conveyor according to the first embodiment, the passenger conveyor according to the second embodiment also reduces the frictional force with the moving handrail 3 and reduces the component dimensions. The tension of the movable handrail 3 can be adjusted and the width direction can be guided.

[Third Embodiment]
Next, a third embodiment of the present invention will be described. Note that in the third embodiment, a description of the same components as those in the first embodiment will not be repeated. In the third embodiment, the arrangement of the guide receiver 2 is different from that of the first embodiment. Other configurations are the same as those of the first embodiment.

  FIG. 6 shows the arrangement of the guide receiver 2 in the third embodiment of the present invention in the same manner as FIG. The guide receiver 2 is supported so as to be located on the outer side of the moving handrail 3.

  In the same manner as described for the passenger conveyor according to the first embodiment, the passenger conveyor according to the third embodiment also reduces the frictional force with the moving handrail 3 and reduces the component dimensions. The tension of the movable handrail 3 can be adjusted and the width direction can be guided.

  In addition, when the guide receiver 2 is disposed right above the center in the width direction of the movable handrail 3 as in the first embodiment, the overall dimensions of the guide receiver 2 and the rollers 1a to 1c can be reduced. There are advantages. On the other hand, in order to arrange the guide receiver 2 on the outer side in the width direction of the moving handrail 3 as in the third embodiment, for example, the push guide support portion 6 of FIG. The passenger conveyor support structure 10 directly supports the guide receiver 2, and further uses a part of the passenger conveyor support structure 10 itself as the guide receiver 2, thereby reducing the number of parts and manufacturing costs of the passenger conveyor. There is an advantage that can be reduced.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described. Note that in the fourth embodiment, a description of the same components as those in the first embodiment will not be repeated. The fourth embodiment differs from the first embodiment in the number and arrangement of rollers supported by the guide receiver 2. Other configurations are the same as those of the first embodiment.

  FIG. 7 shows the number and arrangement of rollers in the second embodiment of the present invention in the same manner as FIG. Six rollers 1a to 1f are supported in the same manner as the rollers 1a to 1c of FIGS. Among the rollers 1a to 1f, the rollers 1a, 1c, and 1e and the rollers 1b, 1d, and 1f are such that the moving handrail 3 has a predetermined size or more so as to sandwich the center in the width direction (vertical direction in the drawing) of the moving handrail 3 The center position in the width direction of the roller is shifted from each other at a position for guiding the running so as not to meander. The rollers 1 a, 1 c and 1 e and the rollers 1 b, 1 d, 1 f are arranged with an interval in the width direction of the moving handrail 3. Further, the rollers 1a and 1b, the rollers 1c and 1d, and the rollers 1e and 1f are sequentially arranged in the moving direction of the moving handrail 3 (left-right direction in the drawing). That is, the rollers 1 a to 1 f are arranged in parallel so that two rollers are arranged at intervals in the width direction at the same position in the moving direction of the moving handrail 3.

  According to the passenger conveyor according to the fourth embodiment, the frictional force is somewhat increased as the number of rollers is increased as compared with the first to third embodiments. Compared with the configuration, the frictional force with the moving handrail 3 can be reduced, and the tension of the moving handrail 3 can be adjusted and guided in the width direction. Further, in the same manner as described for the passenger conveyor according to the first embodiment, the component dimensions can be reduced, and the tension of the handrail 3 can be adjusted and the guidance in the width direction can be performed.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described. Note that in the fifth embodiment, a redundant description of portions having the same configuration as that of the third embodiment will be omitted. The fifth embodiment is different from the third embodiment in the parts used as a roller supported by the guide receiver 2. Other configurations are the same as those of the third embodiment.

  FIG. 8 shows parts used as rollers in the fifth embodiment of the present invention. Of the front wheels 8 and the rear wheels 9 which are parts attached to the step 7 of the passenger conveyor, the width of the rear wheel 9 is about 60% of the width h1 of the flat portion 3d of the handrail 3 and is the same as the rear wheel 9. The part is used as a roller supported by the guide receiver 2.

FIG. 9 shows the arrangement of the rear wheels 9 in the fifth embodiment of the present invention in the same manner as FIG. Similar to the rollers 1a to 1c in FIG. 4, three rear wheels 9 are arranged in a staggered manner. As described above, the width h3 of the rear wheel 9 is about 60% of the width h1 of the plane portion 3d of the moving handrail 3. Therefore, the width h3 is larger than the width h2 as in the first to fourth embodiments so far and is more than half of the width h1, so that the moving handrail 3 is arranged at intervals in the width direction. However, the center position in the width direction of the roller is shifted from each other at the position for guiding the traveling so that the moving handrail 3 does not meander over a predetermined size. This is the same as the fourth embodiment.
Although FIG. 9 shows an example in which the rollers 1 a to 1 c are shared with the rear wheel 9, the rollers 1 a to 1 c may be shared with the front wheel 8. That is, the same components as the rollers (front wheel 8 or rear wheel 9) attached to step 7 in order to move step 7 can be used as rollers 1a to 1c.

  In the same manner as described for the passenger conveyor according to the third embodiment, the passenger conveyor according to the fifth embodiment also reduces the frictional force with the moving handrail 3 and reduces the component dimensions. The tension of the movable handrail 3 can be adjusted and the width direction can be guided. However, since the width h3 is larger than the width h2, the frictional force is larger than that in the third embodiment.

  Instead, since the parts used for the passenger conveyor are shared, the manufacturing cost of the passenger conveyor can be reduced.

[Modification]
The embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention described in the claims.

  For example, in the first to third embodiments and the fifth embodiment described above, three rollers are provided, but the first to third embodiments and the fifth embodiment are provided. Four or more rollers may be arranged by repeating the arrangement in the embodiment in the moving direction of the moving handrail 3.

Further, in the fourth embodiment described above, six rollers are arranged in parallel, but an even number of two, four, or eight or more rollers are arranged in parallel as in the fourth embodiment. Also good.
Moreover, this invention is not limited to an escalator, You may apply to an electric road.
