Description

[Technical Field]

[0001] The present specification relates to a people conveyor handrail belt and a people conveyor. [Background technology]

[0002] Conventionally, for example, passenger conveyor handrail belts have a pair of curved turn-back sections that turn back at the lateral ends. The outer circumferential surface of the passenger conveyor handrail belt is formed flat (see, for example, Patent Document 1). This can result in excessive contact areas between the outer circumferential surface of the handrail belt and hands, luggage, etc. Therefore, there is a demand for preventing excessive contact areas between the outer circumferential surface of the handrail belt and the turn-back sections, at least.

[0012] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0013] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0014] An embodiment of a passenger conveyor and passenger conveyor handrail belt will be described below with reference to Figures 1 to 5. Note that the following embodiment is provided as an example to aid in understanding the configuration of the passenger conveyor and passenger conveyor handrail belt, and does not limit the configuration of the passenger conveyor and passenger conveyor handrail belt.

[0015] As shown in Figure 1, the passenger conveyor 1 may include, for example, a structure 2 installed on a main body, a transport unit 3 for transporting people (passengers), a pair of balustrade units 4 (only one is shown in Figure 1) arranged to sandwich the transport unit 3 in a first direction D1, a drive unit 5 for driving the transport unit 3 and the balustrade units 4, and a processing unit 6 for controlling the entire device.

[0016] In each figure, the first direction D1 is the first horizontal direction (also called the "width direction") D1, which is a direction parallel to the horizontal direction, the second direction D2 is the second horizontal direction (also called the "front-to-back direction") D2, which is a direction parallel to the horizontal direction and perpendicular to the first horizontal direction D1, and the third direction D3 is the vertical direction perpendicular to the first horizontal direction D1 and the second horizontal direction D2, which is the up-down direction D3.

[0017] The passenger conveyor 1 according to this embodiment is an escalator with stepped treads for transporting passengers, but is not limited to this configuration. For example, the passenger conveyor 1 may be a moving walkway with flat treads for transporting passengers.

[0018] The structure 2 may include, for example, machine rooms 2a arranged at each end in the second horizontal direction D2, as in this embodiment. The structure 2 may also have, for example, a truss structure or a girder structure made up of multiple frame members.

[0019] The passenger conveyor 1 may, for example, include a floor plate 7 attached to the structure 2 so as to cover the machine room 2a from above, as in this embodiment. As a result, the floor plate 7 constitutes boarding and disembarking sections 1a located at each end of the transport section 3 in the second lateral direction D2 for passengers to get on and off the transport section 3.

[0020] The conveying unit 3 may include, for example, as in this embodiment, an endless annular running unit 3a that rotates and runs when driven by the drive unit 5, and a plurality of steps 3b that are connected to the running unit 3a and run together with the running unit 3a, and have treads for people to stand on. Although not particularly limited, the running unit 3a may be, for example, a roller chain.

[0021] Alternatively, for example, a pair of running sections 3a may be provided spaced apart in the first horizontal direction D1, and multiple steps 3b may be disposed between the pair of running sections 3a, 3a. The steps 3b may be connected to each running section 3a so as to be rotatable about an axis in the first horizontal direction D1.

[0022] The driving unit 5 may include, for example, as in this embodiment, a rotating unit 5a around which a first end of the traveling unit 3a in the second horizontal direction D2 is wound and which rotates about an axis in the first horizontal direction D1, a winding unit 5b around which a second end of the traveling unit 3a in the second horizontal direction D2 is wound, a driving source 5c that rotates the rotating unit 5a, and a braking unit 5d that brakes the rotation of the rotating unit 5a. As a result, the step 3b is reversed by the rotating unit 5a and also reversed by the winding unit 5b.

[0023] Although not particularly limited, the rotating portion 5a may be, for example, a sprocket. Furthermore, although not particularly limited, the winding portion 5b may be, for example, a guide member that guides the traveling portion 3a so that it rotates in the reverse direction, or may be, for example, a rotating member (e.g., a sprocket) around which the traveling portion 3a is wound and which rotates about an axis in the first horizontal direction D1. Furthermore, although not particularly limited, the driving source 5c may be, for example, a motor and an inverter. Furthermore, although not particularly limited, the braking portion 5d may be, for example, a brake.

[0024] The balustrade section 4 is equipped with an endless circular passenger conveyor handrail belt (hereinafter simply referred to as "handrail belt") 10 that rotates and runs. The balustrade section 4 may also be equipped with a balustrade main body section 4a that supports the handrail belt 10, and a cover section 4b that covers the lower part of the balustrade main body section 4a, as in this embodiment. Note that, for example, the handrail belt 10 may run by being driven by the drive section 5, and the running of the handrail belt 10 may be synchronized with the running of the steps 3b.

[0025] The handrail belt 10 has a pair of curved folded portions 10a, 10a that extend in a curved manner so that the running direction is folded back at the end of the second lateral direction D2, and a straight portion 10b that is disposed between the pair of folded portions 10a, 10a and extends in a straight line. The handrail belt 10 may also have a curved portion 10c that is disposed between the straight portions 10b, 10b and extends in a curved manner, for example, as in this embodiment.

[0026] 2, the cover portion 4b may have an entrance / exit portion 4c at the end in the second horizontal direction D2 through which the handrail belt 10 passes. The handrail belt 10 may be arranged so that it passes through the entrance / exit portion 4c at the turn-back portion 10a, as in this embodiment.

[0027] 2 and 3, the balustrade main body 4a may include, for example, a belt guide 4d that guides the handrail belt 10, and a guide support 4e that supports the belt guide 4d. Although not particularly limited, the guide support 4e may be formed of a panel (e.g., a glass panel) as in this embodiment.

[0028] 3, the handrail belt 10 may include, for example, a plate-shaped belt main body 11 located in the center in the first horizontal direction D1, and a belt engagement portion 12 located at an end in the first horizontal direction D1 and engaging with the belt guide portion 4d. The belt guide portion 4d may include, for example, a guide main body 4f with an open top facing the handrail belt 10, and a guide engagement portion 4g protruding from the guide main body 4f in the first horizontal direction D1 and engaging with the belt engagement portion 12, as in this embodiment.

[0029] Then, by engaging the belt engaging portion 12 with the guide engaging portion 4g, for example, the handrail belt 10 is attached to the belt guide portion 4d so as not to come off from the belt guide portion 4d, and also, for example, the handrail belt 10 is guided by sliding along the belt guide portion 4d. Note that the belt engaging portion 12 may be formed so as to extend from the belt main body portion 11 in the first lateral direction D1 and then fold back, as in this embodiment.

[0030] The handrail belt 10 comprises an elastic surface layer 13 that includes the outer peripheral surface 10d of the handrail belt 10, an elastic inner layer 14 that is connected to the inner periphery of the surface layer 13, and a plurality of rigid bodies 15 embedded inside the surface layer 13. Note that in Fig. 3 (as well as Figs. 4 and 8 to 9), the rigid bodies 15 are shown only in the belt main body 11, but they may also be provided in the belt engagement part 12, for example.

[0031] Furthermore, the handrail belt 10 may, for example, as in this embodiment, have a back layer 16 that includes the inner circumferential surface 10e of the handrail belt 10. The back layer 16 is not particularly limited, but may be formed of, for example, canvas (for example, polyester canvas).

[0032] The surface layer 13 is not particularly limited, but may be made of, for example, a resin (e.g., polyurethane). The inner layer 14 is not particularly limited, but may be made of, for example, a resin (e.g., polyurethane). Note that the inner layer 14 may have a reinforcing material (e.g., steel cord) embedded therein.

[0033] The hardness of the inner layer portion 14 is greater than the hardness of the surface layer portion 13. The hardness is measured at room temperature (25°C) using a durometer hardness tester (type A) in accordance with the method specified in JIS K6253-3, for example.

[0034] The rigid body 15 is not particularly limited, and may be formed of, for example, glass, metal, or hard resin. The rigid body 15 may be formed, for example, in a spherical shape as in this embodiment, or may be formed, for example, in a cylindrical shape. The hardness of the rigid body 15 is greater than the hardness of the surface layer portion 13 and the inner layer portion 14.

[0035] The configuration of the passenger conveyor 1 according to this embodiment is as described above, and next we will explain the operation of the handrail belt 10 according to this embodiment. Note that the following operation is provided as an example to help understand the operation of the handrail belt 10, and does not limit the operation of the handrail belt 10.

[0036] As shown in Figures 3 and 5, the outer peripheral surface 10d of the handrail belt 10 is flat in the straight section 10b. Specifically, in the straight section 10b, the outer peripheral surface 10d of the handrail belt 10 is flat when viewed in the running direction (second lateral direction) D2 of the handrail belt 10 as shown in Figure 3, and is flat when viewed in the width direction (first lateral direction) D1 of the handrail belt 10 as shown in Figure 5.

[0037] This increases the area of ​​contact between the straight portion 10b and the outer peripheral surface 10d of the handrail belt 10. Therefore, for example, the frictional force generated between the straight portion 10b and the outer peripheral surface 10d of the handrail belt 10 can be increased, making it possible to continue to grip the handrail belt 10 reliably.

[0038] 4 and 5, in the folded portion 10a, the rigid body 15 protrudes from the surface layer portion 13 due to the extension of the surface layer portion 13. Here, since the hardness of the inner layer portion 14 is greater than the hardness of the surface layer portion 13, the inner layer portion 14 prevents the rigid body 15 from sinking, so that the rigid body 15 can be reliably protruded from the surface layer portion 13.

[0039] As a result, the surface roughness (for example, arithmetic mean height defined in ISO25178) of the outer peripheral surface 10d of the handrail belt 10 at the turning portion 10a is greater than the surface roughness of the outer peripheral surface 10d of the handrail belt 10 at the straight portion 10b. Therefore, the unevenness of the outer peripheral surface 10d of the handrail belt 10 at the turning portion 10a is greater than the unevenness of the outer peripheral surface 10d of the handrail belt 10 at the straight portion 10b.

[0040] In this way, at the turn-back portion 10a, the outer peripheral surface 10d of the handrail belt 10 is uneven. Specifically, at the turn-back portion 10a, the outer peripheral surface 10d of the handrail belt 10 is uneven when viewed in the running direction (circumferential direction) of the handrail belt 10 as shown in Fig. 4, and also uneven when viewed in the width direction (first lateral direction) D1 of the handrail belt 10 as shown in Fig. 5.

[0041] This prevents the area of ​​contact between the turn-back portion 10a and the outer peripheral surface 10d of the handrail belt 10 from becoming too large. Therefore, for example, it is possible to prevent the frictional force generated between the turn-back portion 10a and the outer peripheral surface 10d of the handrail belt 10 from becoming too large.

[0042] As a result, for example, at the turn-back portion 10a, it is possible to prevent the handrail belt 10 from being pulled in. And, for example, in this embodiment, as shown in Fig. 2, the handrail belt 10 enters and exits the entrance / exit portion 4c at the turn-back portion 10a, so it is possible to prevent the handrail belt 10 from being pulled in the entrance / exit portion 4c, and it is also possible to reduce the force with which the handrail belt 10 is pulled in the entrance / exit portion 4c.

[0043] As described above, the passenger conveyor handrail belt 10, as in this embodiment, In a circular passenger conveyor handrail belt 10 that rotates and runs, A pair of curved folded-back portions 10a, 10a are provided so that the running direction is folded back at the end of the lateral direction D2, The outer peripheral surface 10d is uneven at least in the folded portion 10a when viewed in the width direction D1. This configuration is preferred.

[0044] With this configuration, the outer peripheral surface 10d of the handrail belt 10 is uneven at least at the turn-back portion 10a when viewed in the width direction D1. This prevents the area of ​​contact with the outer peripheral surface 10d of the handrail belt 10 from becoming too large, at least at the turn-back portion 10a.

[0045] In addition, the passenger conveyor handrail belt 10, as in this embodiment, A linear portion 10b is disposed between the pair of folded portions 10a, 10a and extends linearly. The surface roughness of the outer peripheral surface 10d at the folded portion 10a is greater than the surface roughness of the outer peripheral surface 10d at the straight portion 10b. This configuration is preferred.

[0046] With this configuration, the surface roughness of the outer peripheral surface 10d of the handrail belt 10 at the turning-back portion 10a is greater than the surface roughness of the outer peripheral surface 10d of the handrail belt 10 at the straight portion 10b. This prevents the contact area with the outer peripheral surface 10d of the handrail belt 10 at the turning-back portion 10a from becoming too large, and also increases the contact area with the outer peripheral surface 10d of the handrail belt 10 at the straight portion 10b.

[0047] In addition, the passenger conveyor handrail belt 10, as in this embodiment, a surface layer portion 13 including the outer peripheral surface 10d and having elasticity; and a rigid body 15 embedded inside the surface layer 13. This configuration is preferred.

[0048] With this configuration, the rigid bodies 15 are embedded inside the elastic surface layer 13. As a result, when the surface layer 13 stretches at the turn-back portions 10a, the rigid bodies 15 protrude from the surface layer 13, and the outer peripheral surface 10d of the handrail belt 10 becomes uneven at the turn-back portions 10a. Therefore, the surface roughness of the outer peripheral surface 10d of the handrail belt 10 at the turn-back portions 10a can be made greater than the surface roughness of the outer peripheral surface 10d of the handrail belt 10 at the straight portions 10b.

[0049] In addition, the passenger conveyor handrail belt 10, as in this embodiment, an inner layer portion 14 connected to the inner periphery of the surface layer portion 13 and having elasticity; The hardness of the inner layer portion 14 is greater than the hardness of the surface layer portion 13. This configuration is preferred.

[0050] With this configuration, the inner layer portion 14 is connected to the inner periphery of the surface layer portion 13, and the hardness of the inner layer portion 14 is greater than the hardness of the surface layer portion 13. As a result, when the surface layer portion 13 stretches at the turn-back portion 10a, the inner layer portion 14 stops the rigid bodies 15 from sinking, so the rigid bodies 15 can be reliably raised from the surface layer portion 13. Therefore, the outer peripheral surface 10d of the handrail belt 10 can be reliably made uneven at the turn-back portion 10a.

[0051] In addition, the passenger conveyor 1, as in this embodiment, The passenger conveyor is provided with a handrail belt 10. This configuration is preferred.

[0052] According to this configuration, it is possible to prevent the area of ​​contact with the outer circumferential surface 10d of the handrail belt 10 from becoming too large at least at the folded-back portion 10a.

[0053] The passenger conveyor 1 and passenger conveyor handrail belt 10 are not limited to the configurations of the above-described embodiments, nor are they limited to the above-described effects. Furthermore, the passenger conveyor 1 and passenger conveyor handrail belt 10 can, of course, be modified in various ways without departing from the spirit of the present invention. For example, it is possible to arbitrarily select one or more of the configurations and methods of the various modified examples described below and adopt them in the configurations and methods of the above-described embodiments.

[0054] (A) In the passenger conveyor handrail belt 10 according to the above embodiment, the uneven shape (specifically, the height) of the outer peripheral surface 10d is changed, so that the surface roughness of the outer peripheral surface 10d at the turning-back portions 10a is greater than the surface roughness of the outer peripheral surface 10d at the straight portions 10b. However, the passenger conveyor handrail belt 10 is not limited to this configuration.

[0055] For example, as shown in Figure 6, in the straight section 10b, the outer surface 10d of the handrail belt 10 may be uneven when viewed in the width direction (first horizontal direction) D1 of the handrail belt 10, and in the folded section 10a, the outer surface 10d of the handrail belt 10 may be uneven when viewed in the width direction (first horizontal direction) D1 of the handrail belt 10.

[0056] 6, for example, the surface roughness of outer peripheral surface 10d at turning-back portions 10a may be the same as the surface roughness of outer peripheral surface 10d at straight portions 10b without changing the uneven shape of outer peripheral surface 10d. That is, outer peripheral surface 10d may have the same unevenness at turning-back portions 10a, straight portions 10b, and curved portions 10c.

[0057] (B) Furthermore, the passenger conveyor handrail belt 10 according to the above embodiment is configured to have an elastic surface layer 13 including the outer circumferential surface 10d, and a rigid body 15 embedded inside the surface layer 13, so that the surface roughness of the outer circumferential surface 10d at the turning-back portions 10a is greater than the surface roughness of the outer circumferential surface 10d at the straight portions 10b. However, the passenger conveyor handrail belt 10 is not limited to this configuration.

[0058] For example, as shown in FIG. 7, the handrail belt 10 may have a surface layer 13 that includes an outer peripheral surface 10d and has elasticity, and the surface layer 13 may have a cut portion 13a extending in the first lateral direction D1, so that the surface roughness of the outer peripheral surface 10d at the folded portion 10a is greater than the surface roughness of the outer peripheral surface 10d at the straight portion 10b.

[0059] According to this configuration, the cut portions 13a are closed in the straight portions 10b, so the outer peripheral surface 10d is flat. On the other hand, the cut portions 13a are opened in the folded portions 10a as the surface layer 13 extends, so the outer peripheral surface 10d is uneven when viewed in the width direction (first horizontal direction) D1. Thus, the surface roughness of the outer peripheral surface 10d in the folded portions 10a is greater than the surface roughness of the outer peripheral surface 10d in the straight portions 10b.

[0060] (C) Furthermore, in the passenger conveyor handrail belt 10 according to the above embodiment, the hardness of the inner layer 14 is greater than the hardness of the surface layer 13. However, the passenger conveyor handrail belt 10 is not limited to this configuration. For example, the hardness of the surface layer 13 may be the same as the hardness of the inner layer 14. In other words, the surface layer 13 and the inner layer 14 may be formed from the same material.

[0061] (D) Furthermore, in the passenger conveyor handrail belt 10 according to the above embodiment, the inner layer 14 is arranged over the entire area between the surface layer 13 and the back layer 16. However, the passenger conveyor handrail belt 10 is not limited to this configuration.

[0062] For example, as shown in Figure 8, the handrail belt 10 may have an inner layer 14 connected to the inner circumference of the surface layer 13, and an intermediate layer 17 connected to the inner circumference of the inner layer 14, and the hardness of the inner layer 14 may be greater than the hardness of the surface layer 13.

[0063] With this configuration, when the surface layer 13 stretches at the turn-back portion 10a, the inner layer 14 prevents the rigid body 15 from sinking, so the rigid body 15 can be reliably raised from the surface layer 13. This ensures that the outer peripheral surface 10d of the handrail belt 10 is uneven at the turn-back portion 10a.

[0064] The hardness of the intermediate layer 17 is not particularly limited, but may be greater than or less than the hardness of the inner layer 14. The hardness of the intermediate layer 17 is not particularly limited, but may be the same as or greater than the hardness of the surface layer 13, or may be less than or greater than the hardness of the surface layer 13. Although not particularly limited, the region between the surface layer 13 and the back layer 16 may be occupied by the inner layer 14 and the intermediate layer 17, as shown in FIG. 8.

[0065] (E) Furthermore, in the passenger conveyor handrail belt 10 according to the above embodiment, the rigid bodies 15 are not embedded in the inner layer portion 14. However, the passenger conveyor handrail belt 10 is not limited to this configuration. For example, the rigid bodies 15 may also be embedded in the inner layer portion 14.

[0066] The density of the rigid bodies 15 in the inner layer portion 14 may be, for example, smaller than the density of the rigid bodies 15 in the surface layer portion 13, or may be, for example, the same as the density of the rigid bodies 15 in the surface layer portion 13, or may be, for example, larger than the density of the rigid bodies 15 in the surface layer portion 13, as shown in Fig. 9. Here, the configuration according to Fig. 9 will be described below.

[0067] (E-1) As shown in Fig. 9, the inner layer portion 14 is connected to the inner periphery of the surface layer portion 13, and the density of the rigid bodies 15 in the inner layer portion 14 is greater than the density of the rigid bodies 15 in the surface layer portion 13. The hardness of the inner layer portion 14 is not particularly limited, but may be, for example, greater than the hardness of the surface layer portion 13, or may be, for example, less than the hardness of the surface layer portion 13, or may be the same as the hardness of the surface layer portion 13, as shown in Fig. 9.

[0068] Then, at the turn-back portion 10a, when the surface layer portion 13 stretches, the rigid bodies 15 inside the first inner layer portion 14a stop the rigid bodies 15 inside the surface layer portion 13 from sinking. This ensures that the rigid bodies 15 inside the surface layer portion 13 rise up from the surface layer portion 13. Therefore, at the turn-back portion 10a, the outer peripheral surface 10d of the handrail belt 10 can be made uneven.

[0069] In this way, the passenger conveyor handrail belt 10, as shown in FIG. an inner layer portion 14 connected to the inner periphery of the surface layer portion 13 and having elasticity; The rigid body 15 is also embedded in the inner layer portion 14, The density of the rigid body 15 in the inner layer portion 14 is greater than the density of the rigid body 15 in the surface layer portion 13. This configuration is preferred.

[0070] With this configuration, when the surface layer 13 stretches at the turn-back portion 10a, the rigid bodies 15 inside the inner layer 14 stop the rigid bodies 15 inside the surface layer 13 from sinking, so the rigid bodies 15 inside the surface layer 13 can be reliably raised from the surface layer 13. Therefore, the outer peripheral surface 10d of the handrail belt 10 can be reliably made uneven at the turn-back portion 10a.

[0071] (F) For example, the order of execution of each step, such as the operations, procedures, steps, and stages, in the methods and apparatuses shown in the claims, specifications, and drawings, can be implemented in any order, as long as the result of a previous step is not used in a subsequent step. For example, even if a description is made using "first," "next," etc. for convenience, this does not mean that the steps must be executed in that order. [Explanation of symbols]
