Detailed Description
Embodiment 1.
The structure of the passenger conveyor 1a in embodiment 1 will be described. Fig. 1 is a diagram showing a passenger conveyor 1 a. In fig. 1, a passenger conveyor 1a is provided across a subfloor 2a and an upper floor 2b of a building. The passenger conveyor 1a is formed with a post section 8, a straight section 9, a curved section 10, a straight section 9, and a post section 8 from the lower floor 2a toward the upper floor 2 b. Hereinafter, the end post 8 and the curved portion 10 are referred to as a curved section 40.
In fig. 1, the passenger conveyor 1a includes a truss 3, a plurality of steps 4 supported by the truss 3 and connected in a ring shape, a pair of balustrades 5 provided on the truss 3 and provided on both sides in the width direction of the steps 4 in the moving direction of the plurality of steps 4, a moving handrail 6 provided on the upper portion of the pair of balustrades 5 and moving in synchronization with the plurality of steps 4, a skirt plate 7 provided on the lower portion of the pair of balustrades 5, and a driving device 30 not shown in the drawing that supplies power to rotate the moving handrail 6 around the balustrades 5.
Fig. 2 is a diagram showing the internal structure of the end post 8. Fig. 3 is a cross-sectional view A-A of fig. 1, showing a cross-sectional view of the balustrade 5 and the moving handrail 6. In fig. 2 and 3, the balustrade 5 includes a guardrail 12 and a panel 11 constituting a base of the balustrade 5. Further, a roller 13 and a roller shaft 14 are provided between the balustrade 5 and the moving handrail 6.
The guardrail 12 is attached to the upper end surface of the panel 11, and guides the moving handrail 6. In fig. 2, the guardrail 12 is configured by connecting a plurality of guardrail members 15a in the moving direction of the moving handrail 6. Here, one guard rail member 15a is formed in a shape in which the guard rail 12 is divided in the moving direction of the moving handrail 6. For example, as shown in fig. 2, the guard rail member 15a is formed in a shape in which the guard rail 12 at the end post portion 8 is divided into 9 parts.
In fig. 3, the guard rail member 15a has a main body portion 17 fitted to the panel 11, a roller mounting portion 18 extending from the main body portion 17 toward the moving handrail 6 for mounting the roller 13 provided between the guard rail 12 and the moving handrail 6, and a moving handrail supporting portion 19 extending from the roller mounting portion 18 toward the widthwise outer side of the moving handrail 6 for supporting the moving handrail 6. The roller mounting portion 18 extends perpendicularly from the main body portion 17 toward the moving handrail 6, for example, and forms a groove having a concave cross-section.
The guard rail member 15a has a through hole 16 penetrating in the moving direction of the moving handrail 6. For example, as shown in fig. 3, the through hole 16 is provided in the main body 17.
The rollers 13 are provided between the guardrail 12 and the moving handrail 6 to reduce friction generated between the guardrail 12 and the moving handrail 6. The roller shaft 14 is attached to a roller attachment portion 18 of the guardrail 12, and supports the roller 13.
Next, a method for manufacturing the guardrail 12 in the curved section 40 will be described. In manufacturing the guard rail 12 in the curvilinear section 40, first, a plurality of guard rail members 15a are formed by casting. The casting is, for example, lost wax casting. Next, the wire 20 is passed through the through-holes 16 of the respective guard rail members 15a with respect to the guard rail members 15a after molding. The guard rail member 15a is attached so as to be connected in the moving direction of the moving handrail 6. Thus, the guard rail 12 of the curved section 40 is manufactured with the plurality of guard rail members 15a integrated. As the curved section 40, for example, the guardrail 12 shown in fig. 2 is manufactured in the end post portion 8.
Next, a method for inspecting the guardrail 12 in the curve section 40 at the time of manufacturing or maintenance will be described. Fig. 4 is a flowchart showing a method of inspecting the guardrail 12 in the curve section 40 at the time of manufacture or maintenance.
In fig. 4, first, a dimension check is performed to check whether the dimension accuracy of the guardrail 12 is maintained in advance (S1).
Next, when the operator determines that the shape of the guard rail 12 needs to be adjusted by the inspection in S1 (yes in S2), the guard rail member 15a having a portion where the shape of the guard rail 12 needs to be adjusted is taken out (hereinafter, the guard rail member 15a is referred to as a guard rail member 15 b). Specifically, the operator unwinds the wire 20 passing through the through holes 16 of the plurality of guard rail members 15a, separates the plurality of guard rail members 15a from the guard rail 12 integrated by the wire 20, and removes the guard rail members 15b (S3).
Next, the operator adjusts the shape of the portion of the extracted guard rail member 15b that needs to be adjusted (S4). Next, it is checked whether the shape of the entire guard rail member 15b has changed by this adjustment (S5).
When the operator determines that the shape of the guard rail member 15b needs to be adjusted by the inspection in S5 (yes in S6), the operator adjusts the shape of the part of the guard rail member 15b that needs to be adjusted (S4), and further checks whether the shape of the entire guard rail member 15b has changed by the adjustment (S5).
When the operator determines that the shape of the guard rail member 15b does not need to be adjusted by the inspection in S5 (no in S6), the wire 20 is passed through the through holes 16 of the guard rail members 15a including the guard rail member 15b, and the guard rail members 15a including the guard rail member 15b are connected (S7). By this operation, the inspection of the guardrail 12 is ended.
When the operator determines that the shape of the guardrail 12 does not need to be adjusted by the inspection in S1 (no in S2), the inspection of the guardrail 12 is terminated.
In view of the above, the curved section 40 of the guardrail 12 of the passenger conveyor 1a is configured by connecting the plurality of guardrail members 15a constituting the guardrail 12 in the moving direction of the moving handrail 6. The guard rail member 15a is formed by dividing the guard rail 12 in the moving direction of the moving handrail 6. Thus, when the guard rail member 15b having a portion to be adjusted is present at the time of manufacturing or maintenance of the guard rail 12, only the guard rail member 15b can be taken out. Then, the portion of the guard rail member 15a that needs to be adjusted in shape is adjusted to check whether the shape of the entire guard rail member 15b has changed due to the adjustment, and the check of the guard rail 12 is completed. Therefore, it is not necessary to check for a change in the shape of the entire guardrail 12 after adjusting a part of the guardrail 12 as in the conventional guardrail 12. Therefore, the man-hour for the operation at the time of manufacture or maintenance can be reduced.
In addition, the guardrail member 15a has the through-hole 16 penetrating in the moving direction of the moving handrail 6, whereby the assembly of the guardrail member 15a can be simplified.
The method of manufacturing the guardrail 12 of the passenger conveyor 1a includes the steps of molding the guardrail members 15a connected in the moving direction of the moving handrail 6 in the curved section of the guardrail 12 by casting and connecting the guardrail members 15a to each other, whereby the guardrail 12 in the curved section 40 can be manufactured without bending. Therefore, the guardrail 12 can be manufactured while suppressing dimensional changes and cross-sectional shape changes caused by bending. Further, since the manufacturing method is not based on bending, the guard rail member 15a having a complicated structure can be manufactured.
As the guardrail having a complicated structure, for example, a hollow hole into which the roller shaft 14 can be inserted may be formed in the left and right side surface portions of the groove having a concave cross section of the roller mounting portion 18. The roller shaft 14 can be supported by inserting the roller shaft 14 into two hollow holes provided in the left and right side face portions of the groove.
In embodiment 1, the example was described in which the guard rail member 15a was divided into 9 parts in the moving direction of the moving handrail 6 of the guard rail 12, but the number of divided guard rail members 15a in the moving direction of the moving handrail 6 of the guard rail 12 is not limited to this.
In embodiment 1, the example in which the roller mounting portion 18 extends perpendicularly from the main body portion 17 toward the moving handrail 6 and the groove having a concave cross section is formed has been described, but the roller mounting portion 18 is not limited to this as long as it is a shape in which the roller 13 can be mounted and extends from the main body portion 17 toward the moving handrail 6 side.
In embodiment 1, the through hole 16 in the guard rail member 15a is provided in the main body 17 of the guard rail member 15a, but the place where the through hole 16 is provided is not limited as long as the guard rail member 15a is formed so as to be capable of being coupled in the direction in which the moving handrail 6 moves. For example, the roller mounting portion 18 and the moving handrail supporting portion 19a may be provided with the through-hole 16.
In embodiment 1, the example of lost wax casting is given as a molding method of the guard rail member 15a, but the method is not limited thereto as long as the method is a molding method by casting. For example, the molding may be performed by gravity casting with a mold.
In embodiment 1, the inspection in S1 and S5 and the judgment in S2 and S6 are performed by the operator, but the present invention is not limited thereto. For example, a machine that automatically performs inspection and judgment may be used.
In embodiment 1, although the dimension inspection is performed in S1, the specific inspection method in S1 is not limited to the dimension inspection as long as the inspection in which the step of adjusting the shape of the guardrail 12 is envisaged after S1. For example, a material test for investigating whether or not the cross-sectional shape of the guardrail 12 has not changed may be performed.
Embodiment 2.
The structure of the guard rail member 15c of the passenger conveyor 1c in embodiment 2 will be described. Fig. 5 is a cross-sectional view of the balustrade 5c and the moving handrail 6. Fig. 6 is a cross-sectional view of the guard rail member 15 c. The cross section in fig. 5 and 6 shows a cross section in which the passenger conveyor 1c is cut in the same section as the section A-A in the passenger conveyor 1a shown in fig. 1. The passenger conveyor 1c is not shown. The guardrail member 15c in embodiment 2 is different from embodiment 1 in that the hardness of the moving handrail supporting portion 19c is lower than the hardness of the main body portion 17 and the roller mounting portion 18. The same components as those of embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.
In fig. 5 and 6, the rail 5c includes a panel 11 and a rail 12c formed by connecting rail members 15c in the moving direction of the moving handrail 6. The guard rail 12c is not shown.
The guard rail member 15c has a main body portion 17, a roller mounting portion 18, and a moving handrail support portion 19c. The material of the main body 17 and the roller mounting portion 18 is, for example, metal, and the material of the moving handrail supporting portion 19c is, for example, resin.
When the passenger uses the moving handrail 6 in a manner of grasping the moving handrail 6, the palm of the passenger contacts the upper surface of the moving handrail 6, and the fingers of the passenger contact the moving handrail support portion 19c exposed from the moving handrail 6. Here, the moving handrail 6 is made of a material having low hardness such as rubber or urethane in consideration of contact with the hands of the passengers. In addition, since the conventional movable handrail supporting portion 19c is formed as an integral guard rail member 15c, a metal material having high hardness is often used. Therefore, in the balustrade 5c of the conventional passenger conveyor 1c, when the fingers of the passenger strongly contact the conventional moving handrail support 19c, the fingers of the passenger may be injured. On the other hand, in the present embodiment, since the moving handrail supporting portion 19c is made of a material having low hardness, even if the finger of the passenger contacts the moving handrail supporting portion 19c, the possibility of injury to the finger of the passenger can be reduced.
The guard rail member 15c is formed by insert molding. In the insert molding, after the main body portion 17 and the roller mounting portion 18 are molded with metal, the moving handrail supporting portion 19c is molded with resin, thereby integrally molding the main body portion 17, the roller mounting portion 18, and the moving handrail supporting portion 19c.
In view of the above, the guard rail member 15c has a main body portion 17 fitted to the panel 11 constituting the base body of the balustrade 5c, a roller mounting portion 18 extending from the main body portion 17 toward the moving handrail 6 side for mounting the roller 13 provided between the guard rail 12c and the moving handrail 6, and a moving handrail supporting portion 19c extending from the roller mounting portion 18 toward the widthwise outer side of the moving handrail 6 for supporting the moving handrail 6, the moving handrail supporting portion 19c being made of a material having a lower hardness than the materials of the main body portion 17 and the roller mounting portion 18. Thus, when the passenger of the passenger conveyor 1c uses the moving handrail 6 in a manner of grasping the moving handrail, even if the finger of the passenger contacts the moving handrail supporting portion 19c, the possibility of injury to the finger of the passenger can be reduced.
Further, by integrally molding the main body 17, the roller mounting portion 18, and the moving handrail supporting portion 19c, it is not necessary to assemble components divided into the main body 17, the roller mounting portion 18, and the moving handrail supporting portion 19c when manufacturing the guardrail member 15c, and the number of components can be reduced.
In embodiment 2, the material of the main body 17 and the roller mounting portion 18 is metal, and the material of the moving handrail supporting portion 19c is resin, but the material of the main body 17, the roller mounting portion 18, and the moving handrail supporting portion 19c is not limited to this, as long as the hardness of the material of the moving handrail supporting portion 19c is lower than the hardness of the material of the main body 17 and the roller mounting portion 18.
Embodiment 3.
The structure of the guard rail member 15d of the passenger conveyor 1d in embodiment 3 will be described. Fig. 7 is a view showing the guard rail member 15 d. Fig. 7 (a) is a front view of the guard rail member 15d and fig. 7 (b) is a side view of the guard rail member 15 d. Fig. 8 is a diagram showing the internal structure of the end post 8. The passenger conveyor 1d is not shown. The guard rail member 15d in embodiment 3 is different from embodiment 1 in that a concave portion 22 or a convex portion 23 is provided on a surface where the guard rail members 15d contact each other. The same components as those of embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.
In the guard rail member 15d shown in fig. 7 and 8, a concave portion 22 is provided on one surface of the guard rail member 15d that contacts each other, and a convex portion 23 is provided on the other surface. The concave portion 22 and the convex portion 23 can be fitted to each other, and the guard rail 12d is configured by connecting the plurality of guard rail members 15 d. The concave portion 22 and the convex portion 23 are provided, for example, in a lower portion of the main body portion 17 in a face where the guard rail members 15d contact each other. In fig. 8, the portion where the concave portion 22 and the convex portion 23 are fitted is shown as a concave-convex fitting portion 24.
In view of the above, the guard rail member 15d is provided with the concave portion 22 or the convex portion 23 on the surface where the guard rail members 15d contact each other, and the concave portion 22 and the convex portion 23 can be fitted, whereby the assembly of the guard rail member 15a can be simplified.
In embodiment 3, the example was described in which the concave portion 22 and the convex portion 23 are provided at the lower portion of the main body 17 on the surface where the guard rail member 15d contacts each other, but the place where the concave portion 22 and the convex portion 23 are provided is not limited as long as the concave portion 22 and the convex portion 23 can be fitted.
In embodiment 3, the concave portion 22 is provided on one surface of the guardrail member 15d that contacts each other, and the convex portion 23 is provided on the other surface, but the combination of the concave portion 22 and the convex portion 23 provided on the surface of the guardrail member 15d that contacts each other is not limited thereto. The guard rail member 15d may be coupled so that the concave portion 22 and the convex portion 23 can be fitted, for example, the guard rail member 15d may be formed with the concave portion 22 on one surface and the other surface where the guard rail member 15d contacts each other, or may be formed with the convex portion 23 on one surface and the other surface where the guard rail member 15d contacts each other.
