DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions in order to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, some of the components may be omitted in order to facilitate understanding.

[0009] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing 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. In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0010] First, before describing the configuration of the belt roller device, a passenger conveyor in which the belt roller device is used will be described with reference to Fig. 1. Note that the following embodiment is provided as an example to aid in understanding the configuration of the passenger conveyor, and does not limit the configuration of the passenger conveyor.

[0011] As shown in Figure 1, a person 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 section 4, and a processing section 6 for controlling the entire device.

[0012] In Figure 1 (as well as Figures 2 to 5), the first direction D1 is the width direction D1 which is parallel to the horizontal direction, the second direction D2 is the front-to-back direction D2 which is parallel to the horizontal direction and perpendicular to the width direction D1, and the third direction D3 is the vertical direction which is perpendicular to the width direction D1 and the front-to-back direction D2, and is the up-down direction D3.

[0013] The passenger conveyor 1 according to this embodiment is an escalator with a stepped tread surface for transporting passengers, but is not limited to such a configuration. For example, the passenger conveyor 1 may be a moving walkway with a flat tread surface for transporting passengers.

[0014] The transport 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 tread surfaces on which people can stand. Although not particularly limited, the running unit 3a may be, for example, a roller chain.

[0015] Also, for example, the running portions 3a may be provided as a pair separated in the width direction D1, and the steps 3b may be disposed between the pair of running portions 3a, 3a. The steps 3b may be connected to the respective running portions 3a so as to be rotatable about the axis in the width direction D1.

[0016] The drive unit 5 may include, for example, as in this embodiment, a first drive wheel 5a around which a first end of the traveling unit 3a in the front-rear direction D2 is wound and which rotates about an axis in the width direction D1, a traveling support unit 5b that supports a second end of the traveling unit 3a in the front-rear direction D2, a drive source 5c that rotates the first drive wheel 5a, and a first transmission unit 5d that transmits the drive of the drive source 5c to the first drive wheel 5a. As a result, the step 3b is reversed by the first drive wheel 5a and also reversed by the traveling support unit 5b.

[0017] Although not particularly limited, the first driving wheel 5a may be, for example, a sprocket. Although not particularly limited, the running support part 5b may be, for example, a guide material that guides the running part 3a to turn in the opposite direction, or may be, for example, a rotating material (for example, a sprocket) around which the running part 3a is wound and which rotates about an axis in the width direction D1. Although not particularly limited, the driving source 5c may be, for example, a motor. Although not particularly limited, the first transmission part 5d may be, for example, a belt or a chain.

[0018] The balustrade portion 4 may include, for example, an endless circular handrail belt 4a that rotates and runs, a belt support portion 4b that supports the handrail belt 4a, a balustrade main body portion 4c that supports the belt support portion 4b, a cover portion 4d that covers the lower portion of the balustrade main body portion 4c, and first to third belt roller devices 10, 4e, 4f having rollers that contact the handrail belt 4a.

[0019] The first to third belt roller devices 10, 4e, and 4f are not particularly limited. The first belt roller device 10 may be, for example, a belt drive device 10 that applies drive to the handrail belt 4a as in this embodiment. The second belt roller device 4e may be, for example, a belt guide device 4e that guides the handrail belt 4a as in this embodiment. The third belt roller device 4f may be, for example, a belt tension device 4f that applies tension to the handrail belt 4a as in this embodiment.

[0020] Next, one embodiment of the first belt roller device 10 will be described with reference to Figures 2 to 5. Note that the following embodiment is provided as an example to aid in understanding the configuration of the first belt roller device 10, and is not intended to limit the configuration of the first belt roller device 10.

[0021] As shown in FIG. 2, the first belt roller device (hereinafter also simply referred to as the "belt roller device") 10 may include, for example, a device main body 11 fixed to the structure 2 or the balustrade main body 4c, a plurality of drive rollers 12 that contact the handrail belt 4a and are rotatably connected to the device main body 11, a roller unit 20 having a clamping roller 21 that clamps the handrail belt 4a between the drive roller 12, and a force application section 13 that applies force to the roller unit 20 so that the clamping roller 21 comes into contact with and pressurizes the handrail belt 4a.

[0022] Furthermore, the drive unit 5 may include, for example, as in this embodiment, a second transmission unit 5e that transmits the drive of the first drive wheel 5a (see FIG. 1) to the drive roller 12. The second transmission unit 5e may include, for example, as in this embodiment, a rotatable second drive wheel 5f, a first transmission member 5g that transmits the drive of the first drive wheel 5a to the second drive wheel 5f, and a second transmission member 5h that transmits the drive of the second drive wheel 5f to the drive roller 12.

[0023] As a result, the second transmission part 5e transmits the drive of the first drive wheel 5a to the drive roller 12, so that the running part 3a and the handrail belt 4a run by receiving drive from the common drive source 5c. Therefore, the running of the handrail belt 4a is synchronized with the running of the steps 3b, and the running speed of the handrail belt 4a is proportional to the running speed of the steps 3b (specifically, it is the same as the running speed of the steps 3b).

[0024] Although not particularly limited, the first transmission member 5g may be, for example, a belt or a chain, and the second transmission member 5h may be, for example, a belt or a chain. Also, the belt roller device 10 may include a tension roller 14 that presses and contacts the second transmission member 5h to apply tension to the second transmission member 5h, as in the present embodiment.

[0025] 2 and 3, the force application section 13 may include, for example, a force application main body section 13c rotatably connected to the roller unit 20 and the device main body 11, respectively, and an elastic section 13d that applies an elastic restoring force to the force application main body section 13c. The force application main body section 13c may include, for example, a first rotating shaft section 13a that rotatably connects the roller unit 20, and a second rotating shaft section 13b that is rotatably connected to the device main body 11, as in this embodiment.

[0026] As a result, the pinch roller 21 presses against the handrail belt 4a and contacts it, so the drive roller 12 and the pinch roller 21 pinch the handrail belt 4a while pressing against it. Therefore, for example, the handrail belt 4a can be prevented from slipping against the drive roller 12, so the drive of the drive roller 12 can be reliably transmitted to the handrail belt 4a. In addition, in Figures 2 to 5, the fourth direction D4 is a direction perpendicular to the handrail belt 4a when viewed from the width direction D1.

[0027] 4 and 5, the roller unit 20 may include, for example, a unit body 22, a shaft body 23 inserted into the unit body 22, a first bearing 24 rotatably connecting the shaft body 23 and the pinch roller 21, and second bearings 25, 25 inserted into the unit body 22. Note that the roller unit 20 may include, for example, a bolt 26 screwed into the shaft body 23, and a plate 27 and a washer 28 sandwiched between the head of the bolt 26 and the unit body 22, as in this embodiment.

[0028] The unit body 22 may, for example, as in this embodiment, include a pair of first body holes 22a, 22a into which the shaft body 23 is inserted, and a second body hole 22b disposed between the pair of first body holes 22a, 22a into which the second bearing 25 is inserted. Note that the first rotating shaft portion 13a (see FIG. 3) of the force application portion 13 is inserted into the second bearing 25, whereby the roller unit 20 is rotatably connected to the force application body portion 13c.

[0029] The shaft body 23 may, for example, as in this embodiment, include a shaft portion 23a inserted into the first bearing 24, an insert portion 23b inserted into the first body hole 22a of the unit body 22, and a flange portion 23c disposed between the shaft portion 23a and the insert portion 23b. Note that the insert portion 23b may include, for example, a female screw hole into which the bolt 26 screws.

[0030] The first bearing 24 is not particularly limited, but may be, for example, a bearing as in this embodiment. Also, the first bearing 24 may be harder than the pinch roller 21. Although not particularly limited, the pinch roller 21 may be made of, for example, resin, and the first bearing 24 may be made of, for example, metal.

[0031] The second bearing 25 is not particularly limited, and may be, for example, a bush as in this embodiment. As a result, the second bearing 25 includes a component tubular portion 25a formed in a tubular shape.

[0032] Next, a first manufacturing apparatus according to the present embodiment will be described with reference to Fig. 6. Note that the following configuration is provided as an example to aid in understanding the configuration of the manufacturing apparatus, and is not intended to limit the configuration of the manufacturing apparatus.

[0033] As shown in Fig. 6, the first manufacturing device may include, for example, a press machine 30 and a first manufacturing tool 40 that is detachable from the press machine 30. In Fig. 6 (as well as Figs. 7 to 19), the first direction D5 is a first lateral direction D5 that is parallel to the horizontal direction, the second direction D6 is a second lateral direction D6 that is parallel to the horizontal direction and perpendicular to the first lateral direction D5, and the third direction D7 is a vertical direction that is perpendicular to the first lateral direction D5 and the second lateral direction D6, that is, an up-down direction D7.

[0034] The press machine 30 may include, for example, a bolster 31 having a flat upper surface, and a slide 32 that is disposed above the bolster 31 and moves in a vertical direction D7 relative to the bolster 31. Although not particularly limited, the press machine 30 may be, for example, an electric press machine, a hydraulic press machine, or a manual press machine (a man-powered press machine).

[0035] The bolster 31 may have a bolster hole 31a recessed from the upper surface as in this embodiment. The center of the bolster hole 31a may coincide with the center of the slide 32 when viewed in the up-down direction D7.

[0036] For example, the slide 32 may perform a reciprocating motion in which the slide 32 moves from an upper limit position to a lower limit position and then returns to the upper limit position. Note that, for example, the upper limit position of the slide 32 may be arbitrarily changeable, and, for example, the lower limit position of the slide 32 may be arbitrarily changeable.

[0037] The first manufacturing tool 40 may include, for example, a first lower tool 41 attached to the bolster 31 and a first upper tool 42 attached to the slide 32, as in this embodiment. The press machine 30 and the first manufacturing tool 40 press the second part 10b (see FIG. 8) into the first part 10a (see FIG. 7) of the belt roller device 10, thereby fixing the second part 10b to the first part 10a.

[0038] The first lower tool 41 may include, for example, as in this embodiment, a base portion 41a placed on the bolster 31, an attachment portion 41b attached to the bolster 31, and a holding portion 41c that holds the first component 10a. For example, as in this embodiment, the attachment portion 41b may protrude downward from the base portion 41a and be inserted into the bolster hole 31a.

[0039] The first upper tool 42 may, for example, as in this embodiment, include a tool body 43 attached to the slide 32, and a pusher 44 that is movable in the vertical direction D7 relative to the tool body 43 and pushes the second component 10b downward. The tool body 43 may, for example, as in this embodiment, include a lower contact portion 43a that contacts the pusher 44 from below, and an upper contact portion 43b that contacts the pusher 44 from above.

[0040] As a result, the pressing body 44 is slidable relative to the tool body 43 from a lower contact position (lower limit position) where it is stopped by the lower contact portion 43a to an upper contact position (upper limit position) where it is stopped by the upper contact portion 43b. When no external force is applied to the pressing body 44, the pressing body 44 is stopped by the lower contact portion 43a, and the tool body 43 supports the pressing body 44.

[0041] Next, a method for manufacturing belt roller device 10 using the first manufacturing apparatus will be described with reference to Figures 7 to 10. Note that the following method is provided as an example to aid in understanding the manufacturing method of belt roller device 10, and is not intended to limit the manufacturing method of belt roller device 10.

[0042] <Holding process> First, a holding step is performed. As shown in Fig. 7, first part 10a of belt roller device 10 is unit body 22 of roller unit 20. Note that up-down direction D7 of each part of roller unit 20 in Figs. 7 to 10 is opposite to up-down direction D3 of each part of roller unit 20 in Figs. 1 to 5.

[0043] For example, as in this embodiment, the holding portion 41c of the first lower tool 41 may protrude upward from the base portion 41a and be inserted into the second body hole 22b of the unit body 22. In this way, the holding portion 41c of the first lower tool 41 holds the unit body 22.

[0044] <Pre-pressing process> Next, a pre-pushing process is performed. As shown in Fig. 8, the second part 10b of the belt roller device 10 is the second bearing 25 of the roller unit 20. The pushing body 44 may include, for example, as in this embodiment, an insertion part 44a that is inserted into the part cylindrical part 25a of the second bearing 25 that is the second part 10b, and a pushing part 44b that is disposed above the insertion part 44a and protrudes in the lateral directions D5 and D6 beyond the insertion part 44a in order to push the part cylindrical part 25a.

[0045] Also, although not particularly limited, for example, the second bearing 25 may be a magnetic body (specifically, a ferromagnetic body), and the insertion portion 44a may be provided with a magnet, so that the second bearing 25 is held in the insertion portion 44a by magnetic force.

[0046] When the slide 32 is located at the upper limit position (the position shown in FIG. 8 ), the second bearing 25 is sandwiched between the pressing body 44 and the unit body 22 in the vertical direction D7, and the second bearing 25 is positioned relative to the unit body 22. At this time, since the lower contact portion 43a is separated downward from the pressing body 44 (i.e., since the pressing body 44 is located above the lower contact position), the weight of the pressing body 44 is applied to the second bearing 25. As a result, the second bearing 25 is held by the pressing body 44 and the unit body 22.

[0047] <Pressing process> Next, the pushing step is performed. As shown in Fig. 9, the slide 32 moves downward relative to the bolster 31, so that the tool body 43 moves downward relative to the pushing body 44 and the first lower tool 41. Thereafter, the upper contact portion 43b of the tool body 43 comes into contact with the pushing body 44, so that the slide 32 pushes the pushing body 44 downward via the tool body 43.

[0048] As a result, the pressing body 44 and the tool body 43 move downward relative to the first lower tool 41, and the pressing body 44 presses the second bearing 25 downward. Then, the slide 32 moves to the lower limit position (the position shown in FIG. 9), so that the second bearing 25 is pressed into the second body hole 22b of the unit body 22. In this manner, the second bearing 25 (second part 10b) can be fixed to the unit body 22 (first part 10a) of the belt roller device 10 using the press machine 30.

[0049] Then, as the slide 32 moves upward relative to the bolster 31, the tool body 43 moves upward relative to the first lower tool 41. Thereafter, as shown in Fig. 10, the lower abutment portion 43a of the tool body 43 comes into contact with the pressing body 44, causing the tool body 43 and the pressing body 44 to move upward relative to the first lower tool 41. Although not shown or described, the other second bearing 25 is also similarly pressed into the second body hole 22b of the unit body 22 from the opposite side and fixed.

[0050] Next, a second manufacturing apparatus according to this embodiment will be described with reference to Fig. 11. Note that the following configuration is provided as an example to aid in understanding the configuration of the manufacturing apparatus, and is not intended to limit the configuration of the manufacturing apparatus.

[0051] 11, the second manufacturing apparatus may include, for example, a press machine 30 and a second manufacturing tool 50 that is detachable from the press machine 30. For example, as in this embodiment, the press machine 30 of the second manufacturing apparatus may be the same as the press machine 30 of the first manufacturing apparatus.

[0052] The second manufacturing tool 50 may include, for example, a second lower tool 51 attached to the bolster 31 and a second upper tool 52 attached to the slide 32, as in this embodiment. The press machine 30 and the second manufacturing tool 50 press the second part 10b (see FIG. 13) into the first part 10a (see FIG. 12) of the belt roller device 10, thereby fixing the second part 10b to the first part 10a.

[0053] The second lower tool 51 may include, for example, as in this embodiment, a base portion 51a placed on the bolster 31, an attachment portion 51b attached to the bolster 31, and a holding portion 51c that holds the first component 10a. For example, as in this embodiment, the attachment portion 51b may protrude downward from the base portion 51a and be inserted into the bolster hole 31a.

[0054] The second upper tool 52 may include, for example, as in this embodiment, a tool body 53 attached to the slide 32, and a pusher 54 movable in the vertical direction D7 relative to the tool body 53 and pushing the second component 10b downward. The tool body 53 may include, for example, as in this embodiment, a lower contact portion 53a that contacts the pusher 54 from below, and an upper contact portion 53b that contacts the pusher 54 from above.

[0055] As a result, the pressing body 54 is slidable relative to the tool body 53 from a lower contact position (lower limit position) where it is stopped by the lower contact portion 53a to an upper contact position (upper limit position) where it is stopped by the upper contact portion 53b. When no external force is applied to the pressing body 54, the pressing body 54 is stopped by the lower contact portion 53a, and the tool body 53 supports the pressing body 54.

[0056] Next, a method for manufacturing belt roller device 10 using the second manufacturing apparatus will be described with reference to Figures 12 to 19. Note that the following method is provided as an example to aid in understanding the manufacturing method of belt roller device 10, and is not intended to limit the manufacturing method of belt roller device 10.

[0057] <First holding step> First, a first holding step is performed. As shown in Fig. 12, a first part 10a of the belt roller device 10 is a unit body 22 of the roller unit 20. Note that a vertical direction D7 of each part of the roller unit 20 in Figs. 12 to 19 is opposite to a vertical direction D3 of each part of the roller unit 20 in Figs. 1 to 5.

[0058] For example, as in this embodiment, the holding portion 51c of the second lower tool 51 may protrude upward from the base portion 51a and be inserted into the first body hole 22a of the unit body 22. In this way, the holding portion 51c of the second lower tool 51 holds the unit body 22. Although not shown, for example, a jig other than the second lower tool 51 may be disposed between the unit body 22 and the bolster 31 so that the unit body 22 rests stably on the bolster 31.

[0059] <First pre-push process> Next, the first pre-pushing process is performed. As shown in Fig. 13, the second part 10b of the belt roller device 10 is the shaft body 23 of the roller unit 20. The shaft portion 23a of the shaft body 23 extends in the up-down direction D7, and the flange portion 23c of the shaft body 23a is disposed below the shaft portion 23a and protrudes in the lateral directions D5 and D6 beyond the shaft portion 23a.

[0060] The pushing body 54 may have a pushing tube portion 54a formed in a cylindrical shape from the lower end portion toward the upper side as in the present embodiment. The shaft portion 23a is inserted into the pushing tube portion 54a. Thereafter, while the slide 32 is in the upper limit position (the position shown in FIG. 13), the pushing body 54 and the unit body 22 sandwich the shaft body 23 in the up-down direction D7, so that the shaft body 23 is positioned relative to the unit body 22.

[0061] At this time, since the lower contact portion 53a is separated downward from the pushing body 54 (i.e., since the pushing body 54 is located above the lower contact position), the weight of the pushing body 54 is applied to the shaft body 23. As a result, the shaft body 23 is held by the pushing body 54 and the unit body 22.

[0062] <First pressing process> Next, the first pressing step is performed. As shown in Fig. 14, the slide 32 moves downward relative to the bolster 31, so that the tool body 53 moves downward relative to the pressing body 54 and the second lower tool 51. Thereafter, the upper contact portion 53b of the tool body 53 comes into contact with the pressing body 54, so that the slide 32 presses the pressing body 54 downward via the tool body 53.

[0063] As a result, the pressing body 54 and the tool body 53 move downward relative to the second lower tool 51, and the pressing tube portion 54a of the pressing body 54 presses downward the flange portion 23c of the shaft body 23 with its lower surface. Then, the slide 32 moves to the lower limit position (the position shown in FIG. 14), so that the shaft body 23 is pressed into the first body hole 22a of the unit body 22. In this manner, the pressing machine 30 can be used to fix the shaft body 23 (second part 10b) to the unit body 22 (first part 10a) of the belt roller device 10.

[0064] Then, since the slide 32 moves upward relative to the bolster 31, the tool body 53 moves upward relative to the second lower tool 51. Thereafter, as shown in Fig. 15, the lower contact portion 53a of the tool body 53 comes into contact with the pressing body 54, so that the tool body 53 and the pressing body 54 move upward relative to the second lower tool 51.

[0065] <Second holding process> Next, the second holding step is performed. As shown in Fig. 16, the first part 10a of the belt roller device 10 is a part having the unit body 22 and the shaft body 23 of the roller unit 20. The holding part 51c of the second lower tool 51 holds the unit body 22. Note that the upper limit position and the lower limit position of the slide 32 in Figs. 16 to 19 are different from the upper limit position and the lower limit position of the slide 32 in Figs. 12 to 15, respectively.

[0066] <Second pre-pressing process> Next, the second pre-pushing process is performed. As shown in Fig. 17, the second part 10b of the belt roller device 10 is a part having the sandwiching roller 21 and the first bearing 24. Then, while the slide 32 is located at the upper limit position (the position shown in Fig. 17), the pushing body 54 and the shaft body 23 sandwich the first bearing 24 in the up-down direction D7, so that the first bearing 24 is positioned relative to the shaft body 23.

[0067] At this time, since the lower contact portion 53a is separated downward from the pushing body 54 (i.e., since the pushing body 54 is located above the lower contact position), the weight of the pushing body 54 is applied to the first bearing 24. As a result, the first bearing 24 is held by the pushing body 54 and the shaft body 23.

[0068] <Second pressing process> Next, the second pressing step is performed. As shown in Fig. 18, the slide 32 moves downward relative to the bolster 31, so that the tool body 53 moves downward relative to the pressing body 54 and the second lower tool 51. Thereafter, the upper contact portion 53b of the tool body 53 comes into contact with the pressing body 54, so that the slide 32 presses the pressing body 54 downward via the tool body 53.

[0069] As a result, the pressing body 54 and the tool body 53 move downward relative to the second lower tool 51, and the pressing cylinder portion 54a of the pressing body 54 presses the first bearing 24 downward with its lower surface. Then, as the slide 32 moves to the lower limit position (the position shown in FIG. 18), the first bearing 24 is pressed into the shaft portion 23a of the shaft body 23. In this manner, the first bearing 24 (second part 10b) can be fixed to the shaft body 23 (first part 10a) of the belt roller device 10 using the press machine 30.

[0070] 19, the lower contact portion 53a of the tool body 53 comes into contact with the pressing body 54, causing the tool body 53 and the pressing body 54 to move upward relative to the second lower tool 51.

[0071] Although not shown or described, in a similar manner, another shaft body 23 is fixed to the unit body 22, another first bearing 24 and pinch roller 21 are fixed to the shaft body 23, and bolts 26, plates 27 and washers 28 are fixed to the shaft body 23, thereby completing the roller unit 20. Thereafter, although not shown or described, the drive roller 12, force application section 13, tension roller 14 and roller unit 20 are attached to the device body 11, thereby completing the belt roller device 10.

[0072] [1] From the above, the manufacturing method of the belt roller devices 10, 4e, 4f (in this embodiment, the first belt roller device 10) of the passenger conveyor 1 is as follows, as in this embodiment: A manufacturing method for manufacturing a belt roller device 10 having rollers (drive roller 12, sandwich roller 21) that contact a handrail belt 4a of a passenger conveyor 1 using a press machine 30 and manufacturing tools 40, 50, comprising: The belt roller device 10 includes: A first part 10a; A second part 10b fixed to the first part 10a, The press machine 30 is Bolster 31 and a slide 32 that is disposed above the bolster 31 and moves in a vertical direction D7 relative to the bolster 31; The manufacturing tools 40 and 50 include: A lower tool 41, 51 attached to the bolster 31 and holding the first part 10a; and an upper tool 42, 52 attached to the slide 32 and pushing the second part 10b downward. The manufacturing method includes: a holding step of holding the first part 10a with the lower tools 41 and 51; and a pressing step of moving the upper tool 42, 52 downward relative to the lower tool 41, 51 by the press machine 30 so that the upper tool 42, 52 presses the second part 10b downward and the second part 10b is pressed into the first part 10a. This method is preferred.

[0073] According to this method, the lower tools 41, 51 hold the first part 10a. Then, the press machine 30 moves the upper tools 42, 52 downward relative to the lower tools 41, 51, so that the upper tools 42, 52 press the second part 10b downward, and the second part 10b is pressed into the first part 10a. In this way, the press machine 30 can be used to fix the second part 10b to the first part 10a of the belt roller device (in this embodiment, the first belt roller device 10).

[0074] [2] In addition, the manufacturing method of the above [1] is as follows: The pressing step further includes a pressing step of sandwiching the second part 10b in the up-down direction D7 by the upper tools 42, 52 and the first part 10a so that the second part 10b is positioned relative to the first part 10a. This method is preferred.

[0075] According to this method, the upper tools 42, 52 and the first part 10a sandwich the second part 10b in the up-down direction D7, so that the second part 10b is positioned relative to the first part 10a. Then, the upper tools 42, 52 push the second part 10b downward, so that the second part 10b is appropriately pressed into the first part 10a.

[0076] [3] In the manufacturing method [2] above, as in this embodiment, The upper tools 42 and 52 are A tool body 43, 53 attached to the slide 32; a push body 44, 54 that is movable in the up-down direction D7 relative to the tool body 43, 53 and pushes the second part 10b downward, The pre-pushing step applies the weights of the pushers 44 and 54 to the second part 10b so that the pushers 44 and 54 and the first part 10a sandwich the second part 10b in the up-down direction D7, In the pushing process, the tool bodies 43, 53 come into contact with the pushing bodies 44, 54 in the vertical direction D7, and then the upper tools 42, 52 are moved downward relative to the lower tools 41, 51 so that the tool bodies 43, 53 push the pushing bodies 44, 54 downward. This method is preferred.

[0077] According to this method, the weight of the pushing bodies 44, 54 is applied to the second part 10b, so that the pushing bodies 44, 54 and the first part 10a sandwich the second part 10b in the vertical direction D7, and the second part 10b can be appropriately positioned with respect to the first part 10a. Then, the tool main body 43, 53 abuts against the pushing bodies 44, 54 in the vertical direction D7, and then the tool main body 43, 53 presses the pushing bodies 44, 54 downward, so that the pushing bodies 44, 54 press the second part 10b downward. As a result, the second part 10b is appropriately pressed into the first part 10a.

[0078] [4] In the manufacturing method [3] above, as in this embodiment, The second part 10b (in this embodiment, the second bearing 25) has a part cylindrical part 25a formed in a cylindrical shape at least at an upper end part, The pushing body 44 is An insertion portion 44a to be inserted into the component tubular portion 25a; and a pushing portion 44b that is disposed above the insertion portion 44a and protrudes in the lateral directions D5 and D6 from the insertion portion 44a in order to push the component tube portion 25a. This method is preferred.

[0079] According to this method, the inserting portion 44a is inserted into the component tubular portion 25a, whereby the upper tool (in this embodiment, the first upper tool 42) holds the second component 10b (in this embodiment, the second bearing 25). Then, the pushing portion 44b pushes the component tubular portion 25a, whereby the upper tool 42 pushes the second component 10b downward.

[0080] [5] In the manufacturing method of the above [3] or [4], as in this embodiment, The second part 10b (in this embodiment, the shaft body 23) is A shaft portion 23a extending in the vertical direction D7; a flange portion 23c disposed below the shaft portion 23a and protruding in the lateral directions D5 and D6 from the shaft portion 23a; The pushing body 54 is provided with a pushing cylinder portion 54a formed in a cylindrical shape at least at the lower end portion, The shaft portion 23a is inserted into the pushing cylinder portion 54a, and the lower surface of the pushing cylinder portion 54a pushes the flange portion 23c. This method is preferred.

[0081] According to this method, the shaft portion 23a is inserted into the pushing tube portion 54a, so that the upper tool (in this embodiment, the second upper tool 52) holds the second part 10b (in this embodiment, the shaft body 23). Then, the pushing tube portion 54a presses the flange portion 23c with its lower surface, so that the upper tool 52 presses the second part 10b downward.

[0082] [6] In addition, the manufacturing tools 40 and 50 are A manufacturing method for the belt roller device 10, 4e, 4f (in this embodiment, the first belt roller device 10) of the passenger conveyor 1 according to any one of the above [1] to [5], This configuration is preferred.

[0083] According to such a configuration, the press 30 can be used to fix the second component 10b to the first component 10a of the belt roller device (in this embodiment, the first belt roller device 10).

[0084] The passenger conveyor 1, the manufacturing device, and the manufacturing method are not limited to the configuration of the above-mentioned embodiment, and are not limited to the above-mentioned action and effect. Of course, the passenger conveyor 1, the manufacturing device, and the manufacturing method can be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations and methods related to the various modified examples described below and adopt them in the configurations and methods related to the above-mentioned embodiment.

[0085] (A) In the manufacturing apparatus and manufacturing method according to the above embodiment, the manufacturing object is the roller unit 20 of the belt driving device 10 (first belt roller device 10). However, the manufacturing apparatus and manufacturing method are not limited to this configuration.

[0086] For example, the manufacturing object may be other parts of the belt drive device 10 (the device body 11, the drive roller 12, the force application section 13, the tension roller 14). Also, for example, the manufacturing object may be a belt guide device (second belt roller device) 4e. Also, for example, the manufacturing object may be a belt tension device (third belt roller device) 4f. In short, the manufacturing object may be a belt roller device having a roller that contacts the handrail belt 4a of the passenger conveyor 1.

[0087] (B) In addition, in the manufacturing apparatus and manufacturing method according to the above embodiment, the pre-pushing process is performed after the holding process, and the pressing process is performed after the pre-pushing process. However, the manufacturing apparatus and manufacturing method are not limited to such a configuration. For example, the pre-pushing process may not be performed, and the pressing process may be performed after the holding process. Also, for example, the holding process and the pre-pushing process may be performed simultaneously, and then the pressing process may be performed.
