Description

[Technical Field]

[0001] This specification relates to a people conveyor and a method for manufacturing a people conveyor. [Background technology]

[0002] Conventionally, for example, a passenger conveyor comprises a structure installed on the main body, a support device disposed inside the structure that supports the steps, and a connection device that connects the structure and the support device (for example, Patent Document 1). The structure comprises an upper frame and a lower frame that are disposed at the ends in the width direction and overlap in the vertical direction, and a vertical frame that connects the upper frame and the lower frame.

[0003] In the passenger conveyor disclosed in Patent Document 1, the connecting device connects the vertical frame and the support device. However, depending on the positioning of the vertical frame, the vertical frame may not be usable or may get in the way. This restricts the positioning of the connecting part to the positioning of the vertical frame, so for example, it may not be possible to position the connecting part in a desired position.

DETAILED DESCRIPTION OF THE INVENTION

[0009] 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.

[0010] 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.

[0011] An embodiment of a passenger conveyor will be described below with reference to Figures 1 to 10. Note that the following embodiment is provided as an example to aid in understanding the configuration of the passenger conveyor, and is not intended to limit the configuration of the passenger conveyor.

[0012] As shown in Figure 1, the passenger conveyor 1 may include, for example, a structure 2 installed on a main body, a transport section 3 for transporting people (passengers), a pair of balustrade sections 4 (only one is shown in Figure 1) arranged to sandwich the transport section 3 in a first direction D1, a drive section 5 for driving the transport section 3 and the balustrade sections 4, and a processing section 1a for controlling the entire device.

[0013] In each figure, the first direction D1 is the width direction (also called the "first horizontal direction") D1, which is a direction parallel to the horizontal direction; the second direction D2 is the front-to-back direction (also called the "second horizontal direction") D2, which is a direction parallel to the horizontal direction and perpendicular to the width direction D1; and the third direction D3 is the vertical direction perpendicular to the width direction D1 and the front-to-back direction D2, which is the up-down direction D3.

[0014] The fourth direction D4 is a direction in which the transport unit 3 transports a person at the middle of the front-to-rear direction D2, and is referred to as an inclined direction D4 that is inclined with respect to the front-to-rear direction D2. Note that the second to fourth directions D2 to D4 are directions included in the same predetermined imaginary plane, and the first direction D1 is a direction perpendicular to the imaginary plane.

[0015] 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.

[0016] 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.

[0017] Alternatively, for example, a pair of running portions 3a may be provided spaced apart in the width direction D1, and multiple steps 3b may be disposed between the pair of running portions 3a, 3a. The steps 3b may be connected to each running portion 3a so as to be rotatable about an axis in the width direction D1.

[0018] The balustrade section 4 may include, for example, an endless circular handrail belt 4a that rotates and runs, a balustrade main body section 4b that supports the handrail belt 4a, and a cover section 4c that covers the lower part of the balustrade main body section 4b. Note that, for example, the handrail belt 4a may run by being driven by the drive section 5, and the running of the handrail belt 4a may be synchronized with the running of the steps 3b.

[0019] For example, as in this embodiment, the drive unit 5 may include a rotating unit 5a around which a first end of the running unit 3a in the front-rear direction D2 is wound and which rotates about an axis in the width direction D1, a winding unit 5b around which a second end of the running unit 3a in the front-rear direction D2 is wound, and a drive source 5c that rotates 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.

[0020] Although not particularly limited, the winding portion 5b may be, for example, a guide member that guides the running portion 3a so as to reverse, or may be, for example, a rotating member (e.g., a sprocket) around which the running portion 3a is wound and which rotates about an axis in the width direction D1. Furthermore, although not particularly limited, the driving source 5c may be, for example, a motor.

[0021] 2 and 3, the driving unit 5 is disposed inside the structure 2, for example, as a rotating unit 5a and a winding unit 5b (see FIG. 1), and includes a support device 5d that supports the step 3b (see FIG. 1). Note that the rotating unit 5a may be, for example, a sprocket as in this embodiment.

[0022] The support device 5d may include, for example, as in this embodiment, a cylindrical rotating shaft portion 5e that extends in the width direction D1 and to which the rotating portion 5a is fixed, and a fixed shaft portion 5f that extends in the width direction D1 and is inserted into the rotating shaft portion 5e. Also, the support device 5d may include, for example, as in this embodiment, a guide rail 5g that supports the step 3b by guiding it or that supports the step 3b by guiding the running portion 3a.

[0023] 4, the structure 2 includes an upper frame 2a and a lower frame 2b that are respectively disposed at the ends in the width direction D1 and overlap in the up-down direction D3, and a vertical frame 2c that connects the upper frame 2a and the lower frame 2b. For example, as in this embodiment, the structure 2 may include a first horizontal frame 2d that extends in the directions D2 and D4 that the upper frame 2a and the lower frame 2b extend (hereinafter also referred to as "extension directions"), and a second horizontal frame 2e that extends in the width direction D1.

[0024] In this way, the structure 2 may have a truss structure or a girder structure made up of multiple frame members. Note that the vertical frame 2c may include, for example, a vertical frame that is perpendicular to the upper frame 2a and the lower frame 2b, and an inclined frame that intersects the upper frame 2a and the lower frame 2b at an angle, as in this embodiment.

[0025] 4 to 6, the passenger conveyor 1 is equipped with a connection device 10 that connects the structure 2 and the support device 5d. In this embodiment, the connection device 10 connects the structure 2 and the fixed shaft portion 5f of the support device 5d.

[0026] 4 to 6 only show the structure 2, the fixed shaft portion 5f, and the connection device 10. In addition, in Fig. 5 and Fig. 6 (similarly in Fig. 8 to Fig. 10), the structure 2 is shown by a two-dot chain line, and the fixed shaft portion 5f and the connection device 10 are shown by a solid line.

[0027] 5 and 6, the upper frame 2a may include, for example, an upper horizontal plate 2f arranged along the extension direction D2 and the width direction D1, and an upper vertical plate 2g extending downward from the outer end of the upper horizontal plate 2f in the width direction D1 and arranged perpendicular to the upper horizontal plate 2f. Also, the lower frame 2b may include, for example, as in this embodiment, a lower horizontal plate 2h arranged along the extension direction D2 and the width direction D1, and a lower vertical plate 2i extending upward from the outer end of the lower horizontal plate 2h in the width direction D1 and arranged perpendicular to the lower horizontal plate 2h.

[0028] As shown in Figures 5 to 7, the connection device 10 may include, for example, an upper member 21 arranged at the upper end, a main member 22 having an upper end fixed to the upper member 21, an intermediate member 23 fixed to the lower end of the main member 22, and a lower member 24 arranged at the lower end and fixed to the intermediate member 23.

[0029] The upper member 21 may include, for example, a first fixing portion 21a fixed to the upper horizontal plate 2f of the upper frame 2a, and a second fixing portion 21b fixed to the main body member 22, as in the present embodiment. The first fixing portion 21a may be formed in a plate shape extending along the width direction D1 and the extension direction D2, as in the present embodiment. The second fixing portion 21b may be configured to extend downward from the inner end of the first fixing portion 21a in the width direction D1 and to be formed in a plate shape extending along the extension direction D2 and the up-down direction D3, as in the present embodiment.

[0030] The main body material 22 may, for example, as in this embodiment, have a third fixing portion 22a arranged at the upper end and fixed to the second fixing portion 21b of the upper member 21, a fourth fixing portion 22b arranged at the lower end and fixed to the intermediate material 23, and a main body portion 22c arranged between the third fixing portion 22a and the fourth fixing portion 22b.

[0031] Third fixing portion 22a, fourth fixing portion 22b, and main body portion 22c may be formed in a plate shape extending along extension direction D2 and up-down direction D3, respectively, as in the present embodiment. Note that the thickness (dimension in width direction D1) of third fixing portion 22a and fourth fixing portion 22b may be thinner than the thickness (dimension in width direction D1) of main body portion 22c, as in the present embodiment, for example.

[0032] The intermediate member 23 may include, for example, a fifth fixed portion 23a fixed to the fourth fixed portion 22b of the main member 22, and a sixth fixed portion 23b fixed to the lower member 24, as in the present embodiment. The fifth fixed portion 23a may be formed in a plate shape extending along the extension direction D2 and the up-down direction D3, as in the present embodiment. The sixth fixed portion 23b may be configured to extend outward in the width direction D1 from the lower end of the fifth fixed portion 23a, and to be formed in a plate shape extending along the width direction D1 and the extension direction D2, as in the present embodiment.

[0033] The lower member 24 may be formed in a block shape, for example, as in this embodiment. And, for example, as in this embodiment, the lower member 24 may be configured to support the sixth fixing portion 23b of the intermediate member 23 from below, and to be supported from below by the lower horizontal plate 2h of the lower frame 2b.

[0034] Furthermore, the lower member 24 may include, for example, a seventh fixing portion 24a fixed to the sixth fixing portion 23b of the upper intermediate member 23 and an eighth fixing portion 24b fixed to the lower vertical plate 2i of the lower frame 2b, as in the present embodiment. The seventh fixing portion 24a may be formed in a plate shape extending along the width direction D1 and the extension direction D2, as in the present embodiment. The eighth fixing portion 24b may be configured to extend downward from the outer end of the seventh fixing portion 24a in the width direction D1 and to be formed in a plate shape extending along the extension direction D2 and the up-down direction D3, as in the present embodiment.

[0035] 5 to 7 do not show the fastening means for fastening the upper frame 2a and the first fastening portion 21a, the fastening means for fastening the lower frame 2b and the eighth fastening portion 24b, and the fastening means for fastening the fastening portions 21b and 22a (22b and 23a; 23b and 24a) together. Furthermore, the fastening means is not particularly limited and may be, for example, welding or fastening means (for example, bolts and nuts).

[0036] The connection device 10 includes a plate-shaped upper mounting portion 11 that is placed on the upper frame 2a. Although not particularly limited, in this embodiment, the upper mounting portion 11 is configured by a first fixing portion 21a of the upper member 21.

[0037] The connecting device 10 also includes a support portion 12 that supports the fixed shaft portion 5f of the supporting device 5d, and a connecting portion 13 that extends in a plate-like shape in the vertical direction D3 from the upper placing portion 11 to at least the support portion 12 in order to connect the upper placing portion 11 and the support portion 12. Although not particularly limited, in this embodiment, the connecting portion 13 is configured by the second fixing portion 21b of the upper member 21, the main body member 22, and the fifth fixing portion 23a of the intermediate member 23.

[0038] As a result, the upper placing portion 11 and the support portion 12 are connected by the connection portion 13. Therefore, since the support device 5d is supported on the upper frame 2a of the structure 2 by the upper placing portion 11, the support portion 12, and the connection portion 13, the support device 5d can be supported on the structure 2 without using the vertical frame 2c.

[0039] Moreover, because the connection parts 13 are disposed inward of the vertical frames 2c in the width direction D1, the connection parts 13 can be disposed without being obstructed by the vertical frames 2c, for example. As a result, the arrangement of the connection parts 13 can be prevented from being restricted by the arrangement of the vertical frames 2c.

[0040] Furthermore, the connecting portions 13 may be disposed outward in the width direction D1 relative to the supporting portions 12, as in the present embodiment. Specifically, the supporting portions 12 may be fixed to the inner surfaces of the connecting portions 13 in the width direction D1, as in the present embodiment. Note that the fixing means (not shown in FIGS. 5 to 7) for fixing the connecting portions 13 and the supporting portions 12 together is not particularly limited, and may be, for example, welding, or may be, for example, fastening means (for example, bolts and nuts).

[0041] The connection device 10 also includes a lower mounting portion 14 that is placed on the lower frame 2b and supports the connection portion 13 from below. Although not particularly limited, in this embodiment, the lower mounting portion 14 is configured by the sixth fixing portion 23b of the intermediate member 23 and the lower member 24.

[0042] The length of the lower mounting portion 14 in the extension direction D2 is shorter than the length of the upper mounting portion 11 in the extension direction D2. Note that the length of the fourth fixing portion 22b in the extension direction D2 (specifically, the sum of the lengths of the two fourth fixing portions 22b, 22b in the extension direction D2) may be longer than the length of the third fixing portion 22a in the extension direction D2, for example, as in this embodiment.

[0043] The support part 12 has an opening 16 into which the end of the fixed shaft part 5f is inserted. The opening 16 has a first opening 17 and a second opening 18 connected to the first opening 17 and having an inner width wider than the inner width of the first opening 17.

[0044] First opening 17 has opening portion 17a that is open to the outside so that the end of fixed shaft portion 5f can be inserted and removed, and second opening 18 has opening support portion 18a that supports the end of fixed shaft portion 5f from below. For example, as in this embodiment, first opening 17 may be connected to the upper end of second opening 18, and opening portion 17a may open first opening 17 upward.

[0045] The connection device 10 is provided with a cylindrical holding portion 19 that holds the end of the fixed shaft portion 5f in the second opening 18. The end of the fixed shaft portion 5f is inserted into the inside of the holding portion 19, which is inserted into the inside of the second opening 18, and the outer width of the holding portion 19 is wider than the inner width of the first opening 17. This prevents the holding portion 19 from coming off the second opening 18, so that the end of the fixed shaft portion 5f is held by the holding portion 19 in the extension direction D2 and the up-down direction D3.

[0046] The holding portion 19 can be inserted into and removed from the second opening 18 by being moved in the width direction D1 relative to the fixed shaft portion 5f. The holding portion 19 may be fixed to the support portion 12 by, for example, a fixing means (for example, a bolt and a nut), or may be pressed into contact with the support portion 12 in the width direction D1 by, for example, a pressing means (for example, a spring).

[0047] The connecting portion 13 also includes an abutment portion 13a that covers the opening 16 from the outside in the width direction D1. As a result, the abutment portion 13a abuts and stops the end of the fixed shaft portion 5f in the width direction D1, so that the fixed shaft portion 5f is held by the abutment portion 13a in the width direction D1.

[0048] The configuration of the passenger conveyor 1 according to this embodiment is as described above, and next, a manufacturing method for the passenger conveyor 1 according to this embodiment will be described with reference to Figures 8 to 10. Note that the following manufacturing method is provided as an example to aid in understanding the manufacturing method for the passenger conveyor 1, and is not intended to limit the manufacturing method for the passenger conveyor 1.

[0049] Although not particularly limited, in the manufacturing method of the passenger conveyor 1 according to this embodiment, the existing structure 2 is reused, while the transport unit 3 and drive unit 5 are replaced with new devices. Therefore, first, the support device 5d (not shown) of the existing drive unit 5 and the like are removed from the structure 2.

[0050] The structure 2 has a vertical frame 2c that connects the upper frame 2a and the lower frame 2b. For example, when reusing an existing structure 2, it is difficult to grasp the arrangement of the vertical frame 2c. On the other hand, even when reusing an existing structure 2, it is easy to grasp the arrangement of the upper frame 2a.

[0051] Therefore, as shown in FIG. 8 (also see FIGS. 5 to 7), the upper placing portion 11 is placed on the upper frame 2a, and the connecting portion 13 extends in a plate shape in the vertical direction D3 from the upper placing portion 11 to the supporting portion 12. As a result, the upper placing portion 11 and the supporting portion 12 are connected by the connecting portion 13, and the supporting device 5d can be supported on the upper frame 2a of the structure 2 by the upper placing portion 11, the supporting portion 12, and the connecting portion 13. Therefore, for example, the supporting device 5d can be supported on the structure 2 without using the vertical frame 2c of the structure 2.

[0052] Moreover, because the connection portions 13 are disposed inward of the vertical frames 2c in the width direction D1, for example, the connection portions 13 can be disposed without being obstructed by the vertical frames 2c. This prevents the placement of the connection portions 13 from being restricted by the placement of the vertical frames 2c. Therefore, for example, the connection portions 13 can be disposed in a desired position, and the support device 5d can be installed in a desired position.

[0053] Furthermore, the length of the lower placement portion 14 in the extension direction D2 is shorter than the length of the upper placement portion 11 in the extension direction D2. This allows the lower placement portion 14 to be placed on the lower frame 2b, avoiding the vertical frame 2c, while the connecting portion 13 is supported from below by the lower placement portion 14.

[0054] The length of the fourth fixing portion 22b in the extension direction D2 (specifically, the total length of the two fourth fixing portions 22b, 22b in the extension direction D2) is longer than the length of the third fixing portion 22a in the extension direction D2, which allows, for example, further flexibility in the arrangement of the lower placement portion 14.

[0055] Then, with the holding portion 19 inserted into the end of the fixed shaft portion 5f, the support device 5d is moved downward. Note that, although only the fixed shaft portion 5f is shown in Fig. 8 (as well as Figs. 9 and 10), the support device 5d is actually a device that includes not only the fixed shaft portion 5f but also the rotating portion 5a and the rotating shaft portion 5e (see Fig. 3).

[0056] As a result, the end of the fixed shaft portion 5f is inserted into the second opening 18 via the first opening 17 having the open portion 17a, as shown in Fig. 9. At this time, the abutment portion 13a (see Fig. 8) of the connection portion 13 abuts and stops the end of the fixed shaft portion 5f in the width direction D1, so that the fixed shaft portion 5f is held by the abutment portion 13a in the width direction D1.

[0057] 10, the holding portion 19 is inserted into the second opening 18 by being moved outward in the width direction D1 relative to the fixed shaft portion 5f. As a result, the holding portion 19 is prevented from coming off the second opening 18 because the holding portion 19 is wider than the first opening 17.

[0058] Therefore, the end of the fixed shaft portion 5f is held in the second opening 18 in the extension direction D2 and the up-down direction D3 by the holding portion 19. The opening support portion 18a of the second opening 18 supports the end of the fixed shaft portion 5f from below via the holding portion 19.

[0059] Note that by moving the holding portion 19 inward in the width direction D1 relative to the fixed shaft portion 5f, the holding portion 19 can be removed from the second opening 18. Furthermore, by moving the support device 5d including the fixed shaft portion 5f and the like upward from this state, the fixed shaft portion 5f can be removed from the opening 16 via the opening portion 17a.

[0060] [1] As described above, the passenger conveyor 1, as in this embodiment, a structure 2 installed on the skeleton; A support device 5d disposed inside the structure 2 and supporting the step 3b; a connecting device 10 that connects the structure 2 and the support device 5d, The structure 2 is An upper frame 2a and a lower frame 2b are respectively arranged at the ends in the width direction D1 and overlap in the up-down direction D3; A vertical frame 2c that connects the upper frame 2a and the lower frame 2b, The connection device 10 includes: a plate-shaped upper mounting portion 11 placed on the upper frame 2a; A support portion 12 that supports the support device 5d; a connecting portion 13 extending in a plate shape in a vertical direction D3 from the upper placing portion 11 to at least the support portion 12 in order to connect the upper placing portion 11 and the support portion 12; The connection portion 13 is disposed inward of the vertical frame 2c in the width direction D1. This configuration is preferred.

[0061] According to this configuration, the upper mounting portion 11 is placed on the upper frame 2a, and the connecting portion 13 extends in a plate-like shape in the vertical direction D3 from the upper mounting portion 11 to at least the support portion 12, thereby connecting the upper mounting portion 11 and the support portion 12. This allows the support device 5d to be supported on the upper frame 2a of the structure 2 by the upper mounting portion 11, the support portion 12, and the connecting portion 13. Moreover, because the connecting portion 13 is disposed inward from the vertical frame 2c in the width direction D1, the arrangement of the connecting portion 13 can be prevented from being restricted by the arrangement of the vertical frame 2c.

[0062] [2] In addition, in the passenger conveyor 1 described above in [1], as in this embodiment, The support device 5d includes a shaft portion (in this embodiment, a fixed shaft portion) 5f extending in the width direction D1, The support portion 12 has an opening 16 into which the end of the shaft portion 5f is inserted, The opening 16 is an opening 17a that is open to the outside so that the end of the shaft portion 5f can be inserted and removed; and an opening support portion 18a that supports the end portion of the shaft portion 5f from below. This configuration is preferred.

[0063] According to this configuration, opening 16 is open to the outside at opening 17a, and therefore the end of shaft 5f (in this embodiment, fixed shaft) is inserted into and removed from opening 16 via opening 17a. Then, because the end of shaft 5f is inserted into opening 16, the end of shaft 5f is supported from below by opening support 18a of opening 16.

[0064] [3] In addition, in the passenger conveyor 1 described above in [2], as in this embodiment, The opening 16 is a first opening 17 having the opening 17a; a second opening (18) having the opening support portion (18a), connected to the first opening (17) and wider than the first opening (17); The connection device 10 includes a cylindrical holding portion 19 that holds the end of the shaft portion (in this embodiment, a fixed shaft portion) 5f in the second opening 18, The end of the shaft portion 5f is inserted into the holding portion 19, The holding portion 19 is inserted into the second opening 18 and is wider than the first opening 17 so as to be prevented from coming out of the second opening 18. The holding portion 19 can be inserted into and removed from the second opening 18 by being moved in the width direction D1 relative to the shaft portion 5f. The following configuration is also possible.

[0065] According to this configuration, the end of the shaft portion 5f (in this embodiment, the fixed shaft portion) is inserted into the second opening 18 via the first opening 17 having the open portion 17a. Then, the end of the shaft portion 5f is inserted into the inside of the cylindrical holding portion 19, and the holding portion 19 is moved in the width direction D1 relative to the shaft portion 5f, whereby the holding portion 19 is inserted into the inside of the second opening 18.

[0066] Since the holding portion 19 is wider than the first opening 17, the holding portion 19 is prevented from coming off the second opening 18. As a result, the end of the shaft 5f is held in the second opening 18 by the holding portion 19.

[0067] [4] In addition, the passenger conveyor 1 of the above [2] or [3], as in this embodiment, The connection device 10 includes a stop portion 13a that covers the opening 16 from the outside in the width direction D1 and stops the end of the shaft portion 5f in the width direction D1. The following configuration is also possible.
