Summary of the Invention

Problems to be Solved by the Invention

[0004] In the renewal work of an escalator, in order to attach parts with the latest structure to existing trusses and diverted parts, there may be a need for drilling and cutting at about 200 or more locations per unit on site.

[0005] At that time, while looking at the drawing in a dark place, the dimensions from the reference are measured to confirm the hole position, and after making a punch mark or the like, processing is performed with a drill or the like, so the work takes time. Furthermore, due to misreading of dimensions or measurement errors resulting in a deviation of the processing position, there is a risk of defective installation of parts, and risks such as rework of processing and part replacement exist. Also, those problems similarly exist in the new construction work of escalators.

[0006] Therefore, an object of the present disclosure is to provide a processing position specifying device for a passenger conveyor, a set of processing position specifying devices, and a processing method for a passenger conveyor that can easily suppress displacement of a processing position and easily shorten working hours in new construction work or renewal work.

Means for Solving the Problems

[0007] In order to solve the above problems, a processing position specifying device for a passenger conveyor according to the present disclosure is a processing position specifying device used when processing the passenger conveyor using one or more reference positions defined in the passenger conveyor, and includes a main body capable of specifying the position of a reference portion arranged at an arrangement position based on the reference position, and a processing position specifying portion capable of specifying one or more processing positions in a state where the reference portion is located at the arrangement position.

[0008] According to the present disclosure, by arranging the reference portion at the reference position, one or more processing positions can be accurately specified, and marking can be performed on one or more processing positions. Therefore, it is easy to perform processing at one or more processing positions quickly and accurately, so it is easy to suppress displacement of the processing position and easy to shorten the working hours in new construction work or renewal work.

[0009] Further, it is composed of a plate-shaped template made of metal or resin, the template has one or more through holes constituting the processing position specifying portion, and in a state where the reference portion is located at the arrangement position, a position overlapping the through hole may include at least a part of the processing position.

[0010] Note that the processing position may have a portion protruding from a position overlapping the through hole in a state where the reference portion is located at the arrangement position, or all of the processing positions may be included in a position overlapping the through hole in a state where the reference portion is located at the arrangement position.

[0011] According to this configuration, one or more processing positions can be specified quickly and accurately only by arranging the template at a predetermined position. In addition, since the template is hard and difficult to break, the handleability during transportation and the like can also be improved.

[0012] In addition, the processing position specifying device set according to the present disclosure includes a plurality of the templates that are different from each other.

[0013] Generally, it is necessary to form a plurality of sets of a plurality of holes configured with different layouts in a truss, and cutting may be performed. In addition, the sets of a plurality of holes and the cutting process that exist in a plurality also differ depending on the model of the passenger conveyor. Therefore, by preparing a template set composed of a plurality of templates for each model as in this configuration, marking can be performed quickly and accurately at all or most of the processing positions. Therefore, all the holes and all the cutting processes formed in the passenger conveyor can be formed quickly and accurately, or most of the holes and most of the cutting processes can be formed quickly and accurately.

[0014] In addition, the processing position specifying device set may include a hole linear arrangement template having a plurality of the through holes arranged at intervals on a straight line.

[0015] In some cases, a vertical direction extending member (vertical direction extending bracket) extending in a direction perpendicular to the bottom surface of the truss is attached to the truss, and the vertical direction extending member may have holes at intervals in its extending direction. On the other hand, according to this configuration, the processing position specifying device set includes a hole linear arrangement template having a plurality of through holes arranged at intervals on a straight line. Therefore, by providing a plurality of holes arranged at intervals on a straight line in the truss using the hole linear arrangement template, the vertical direction extending member can be easily attached to the truss.

[0016] In addition, the processing position specifying device may include a projection unit that projects the one or more processing positions.

[0017] The inside of the truss is dim. Therefore, a processing drawing can be projected by a projection device including a projection unit such as a projector, and the processing position can be projected.

[0018] According to this configuration, data on the layout of a plurality of sets of a plurality of holes and data on processing positions are stored in the storage unit of the processing position specifying device. While moving the projection device, at each stationary position (each projection position), by appropriately projecting the formation positions of one or more appropriately selected holes and one or more cutting positions, the processing positions of all the holes, all the cutting positions, or most of the holes and most of the cutting positions can be specified and marked quickly and accurately. Therefore, all the holes and all the cutting positions, or most of the holes and most of the cutting positions formed in the passenger conveyor can be formed quickly and accurately.

[0019] Also, by simply swapping data or appropriately selecting one set of data corresponding to the model for which construction is to be performed from a plurality of sets of data, it is possible to easily handle new models and a large number of models, and a processing position specifying device with excellent versatility can be realized. Furthermore, since there is no need to create items such as templates, the processing of the passenger conveyor can be performed at low cost.

[0020] Also, in a state where the reference portion is arranged at the arrangement position, the projection portion may be able to project a plurality of the processing positions that are substantially plane-symmetric with respect to a plane that substantially bisects at least a part of the extending direction of the truss in the width direction of the truss.

[0021] Processing on the side walls of the truss may include processing that is the same on both sides in the width direction of the truss. According to this configuration, since the projection portion can project a plurality of processing positions that are substantially plane-symmetric with respect to a plane that substantially bisects the above-mentioned region in the width direction of the truss, for the same processing on the side wall portions on both sides in the width direction of the truss, simultaneous processing on both sides in the width direction becomes possible. Therefore, the marking of the processing positions of one side wall portion and the other side wall portion can be performed more quickly.

[0022] In addition, the method for machining a passenger conveyor according to the present disclosure is a method for machining a passenger conveyor using the machining position specifying device capable of projecting a plurality of machining positions that are substantially plane-symmetrical with respect to a plane that bisects the region in the width direction of the truss. The method includes a projecting step of projecting, in a state where the reference portion is disposed at the disposing position, the plurality of machining positions that are substantially plane-symmetrical with respect to the plane that bisects the region in the width direction onto the projecting portion, and a marking step of applying marking that enables each machining position to be specified to the plurality of projected machining positions.

[0023] According to the present disclosure, with respect to the same machining on the side wall portions on both sides in the width direction of the truss, machining can be performed simultaneously on both sides in the width direction. Therefore, marking of the machining positions on one side wall and the other side wall can be performed more quickly.

Effect of the Invention

[0024] According to the machining position specifying device, the set of machining position specifying devices, and the method for machining a passenger conveyor according to the present disclosure, displacement of the machining position can be suppressed and the working time can also be shortened.

Embodiments for Carrying Out the Invention

[0026] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the accompanying drawings. In the following, when a plurality of embodiments, modification examples, etc. are included, it is initially assumed that new embodiments can be constructed by appropriately combining their characteristic parts. Also, in the following examples, the same reference numerals are given to the same configurations in the drawings, and redundant explanations are omitted. Also, the plurality of drawings include schematic diagrams, and the dimensional ratios of the vertical, horizontal, height, etc. of each member between different drawings do not necessarily match. Also, among the components described below, components not described in the independent claims indicating the highest-level concept are arbitrary components and are not essential components.

[0027] Also, in the following description, the case where the passenger conveyor whose processing position is specified using the processing position specifying devices 15 and 115 of the present disclosure is the escalator 1 will be described. However, in this specification, the passenger conveyor is defined as an escalator or a moving walkway, and the passenger conveyor whose processing position is specified using the processing position specifying devices 15 and 115 of the present disclosure may be a moving walkway, and more specifically, may be a horizontal moving walkway or an inclined moving walkway.

[0028] FIG. 1 is a perspective view showing the inside of a truss 2 of an escalator 1 under renewal. The escalator 1 includes drive roller rails 4a, 4b, 5a, 5b that guide drive rollers existing on the left and right in the width direction of the steps from both the upper and lower vertical sides, and driven roller rails 6a, 6b that guide driven rollers existing on the left and right in the width direction of the steps. Further, the escalator 1 includes a drive unit located at the upper part, an upper sprocket that receives power from the drive unit via a drive chain, a lower sprocket that circulates the steps between the upper sprocket, and a handrail drive device that receives power from the upper sprocket and applies a force in the moving direction to the moving handrail, etc.

[0029] Therefore, as shown in FIG. 1, in the escalator 1, in order to fix those devices, parts, etc. to the truss 2, various brackets 7, 8, 9 are attached to the side wall portion 10 etc. of the truss 2. The various brackets 7, 8, 9 may include a plurality of vertically extending brackets 9 that are arranged at predetermined intervals in the extending direction of the truss 2 and are attached to the side wall portion 10 of the truss 2 so as to extend in a direction perpendicular to the bottom surface of the truss 2. Further, the vertically extending bracket 9 may have only a plurality of through holes (not shown) that are located in a straight line at intervals in the extending direction, and may be fixed to the side wall portion 10 of the truss 2 using the plurality of through holes.

[0030] The processing of the side wall portion 10 of the truss 2 generally includes many processes (hereinafter referred to as symmetric processing) that are the same processing on both sides in the width direction of the truss 2. The symmetric processing is processing that is substantially plane-symmetric with respect to a plane that substantially bisects at least a part of the extending direction of the truss in the width direction of the truss. In the example shown in FIG. 1, the various brackets 7, 8, 9 include symmetrically installed brackets 7a, 8a, 9a that are attached to the first side wall portion 10a on one side in the width direction of the truss 2 and the second side wall portion 10b on the other side in the width direction of the truss 2 so as to face each other in the width direction of the truss 2. These symmetrically installed brackets 7a, 8a, 9a are fixed using a plurality of holes formed substantially plane-symmetrically with respect to the bisecting plane on the side wall portions 10a, 10b on both sides in the width direction of the truss 2 by symmetric processing.

[0031] (First Embodiment) Next, the processing position specifying device 15 according to the first embodiment of the present disclosure used to specify the processing position during the processing of the escalator 1 will be described. FIG. 2(a) is a plan view of the template 20 constituting the processing position specifying device 15 according to the first embodiment as viewed from one side in the thickness direction, and FIG. 2(b) is a plan view showing one reference region 19 in the truss 2. The template 20 is used when processing the escalator 1 using one or more reference positions 11 defined in the escalator 1.

[0032] The template 20 is an example of a hole linear arrangement template and is used to specify the positions of a plurality of holes provided in the side wall portions 10a and 10b of the truss 2 in order to fix the longitudinally extending bracket 9 to the truss 2. The template 20 is a plate member and is made of metal or resin. As shown in FIG. 2, the surfaces on both sides in the thickness direction of the template 20 have an elongated rectangular shape. The template 20 has a plurality of through holes 21 that are located in a straight line at intervals in the longitudinal direction (the longitudinal direction of both side surfaces). Each through hole 21 has, for example, a cylindrical shape. In the template 20 shown in FIG. 2(a), all the through holes 21 are located in a straight line, but the hole linear arrangement template may have both a plurality of through holes located in a straight line and one or more other through holes. Further, the planar shape of the through hole is not limited to a circular shape and may be any shape.

[0033] The processing using the template 20 is performed as follows, for example. The reference region 19 surrounded by the dotted line in Fig. 2(b) has a planar shape that substantially matches the planar shape of the corresponding template 20, and in this embodiment, it has a rectangular planar shape. First, the first corner 22a (the upper left corner in Fig. 2(a)) of the four corners 22 of the template 20 coincides with the corresponding first corner 19a (the upper left corner in Fig. 2(b)) in the reference region 19, and the second corner 22b (the lower right corner in Fig. 2(a)) of the template 20 coincides with the corresponding second corner 19b (the lower right corner in Fig. 2(b)) in the reference region 19, and one side surface in the thickness direction of the template 20 is brought into contact with the wall surface of the side wall portion 10 of the truss 2. The first corner 19a and the second corner 19b are an example of the reference position 11 for one reference region 19 and also an example of the arrangement position 16, and the first corner 22a and the second corner 22b are an example of the reference portion 17.

[0034] Here, each reference position 11 of the escalator 1 is determined as follows, for example. The position information of a set of a plurality of holes 14 at which a plurality of processing positions 18 (see Fig. 2(b)) are specified using the template 20 is described in the design drawing, and the positions of the plurality of holes in the design drawing and the formation positions of the plurality of holes 14 in the corresponding truss 2 correspond one-to-one. Therefore, the positions of the sets of the plurality of holes 14 in the truss 2, and thus the reference positions 11 (constituted by two corners 19a and 19b in this embodiment) that can be specified by the positions of the sets of the plurality of holes 14 are uniquely determined based on the position information of the corresponding plurality of holes in the design drawing.

[0035] Furthermore, the relative positions of the centers of each of the plurality of holes 14 with respect to the center of one of the holes 14 in which the processing position 18 of the truss 2 is specified using the template 20 coincide with the relative positions of the centers of each of the plurality of through holes 21 with respect to the center of one of the through holes 21 provided in the template 20. Therefore, by arranging the reference portion 17 of the template 20 at the arrangement position 16 based on the reference position 11, the formation positions of the plurality of holes 14 corresponding to the plurality of through holes 21 can be accurately and quickly specified. The template 20 is an example of the main body of the processing position specifying device 15, the plurality of holes 14 (all the holes 14) are an example of one or more processing positions, and the plurality of through holes 21 (all the through holes 21) provided in the template 20 are an example of the processing position specifying portion 27.

[0036] After finishing arranging the two corners 19a, 19b of the template 20 at the reference position 11 of the side wall portion 10 of the truss 2, marking is then performed. This marking is performed, for example, by applying paint or making a mark with a magic marker or the like at the positions corresponding to the respective through holes 21 from the side opposite to the contact surface side of the template 20 with respect to the truss 2. Thereafter, when a predetermined hole is formed in the truss 2 at the marked position with a drill or the like, a plurality of holes 14 for attaching the longitudinal extension bracket 9 corresponding to the one reference position 11 can be accurately formed in the truss 2.

[0037] As described above, a plurality of identical longitudinal extension brackets 9 are attached to both of the side wall portions 10a, 10b on both sides in the width direction of the truss 2, and the plurality of longitudinal extension brackets 9 are attached to each of the side wall portions 10a, 10b at intervals in the extension direction of the truss 2. Therefore, by simply changing the reference position 11 sequentially using the same template 20 and performing the same processing as the above processing, all the holes necessary for attaching all the longitudinal extension brackets 9 can be formed in the truss 2.

[0038] The escalator 1 includes a plurality of different brackets 7, 8, 9. For each of the brackets 7, 8, 9, a corresponding template for the mounting process can be prepared, just as the template 20 is for the mounting process of the bracket 9. Here, as is clear from the above description, the positional relationship of the plurality of through holes (centers of the through holes) provided in each of the brackets 7, 8, 9 coincides with the positional relationship of the plurality of through holes 21 (centers of the through holes 21) provided in the corresponding template 20, and also coincides with the positional relationship of the plurality of holes 14 (centers of the holes 14) provided in the truss 2 for attaching each of the brackets 7, 8, 9 to the truss 2.

[0039] It is preferable to prepare a processing position specifying device set 50 including a plurality of templates 20 corresponding to each of the plurality of brackets 7, 8, 9 of the escalator 1. The processing position specifying device set 50 may include, for example, in addition to the template 20, a template 25 whose plan view on one side in the thickness direction is shown in FIG. 3. Further, the plurality of through holes 26 formed in the template 25 may include through holes 26a arranged in a matrix. Further, the processing position specifying device set 50 may further include templates such as U-shaped and H-shaped templates in addition to the I-shaped template 20 and the L-shaped template 25. The plurality of brackets 7, 8, 9 corresponding to the corresponding templates 20 may or may not be all different brackets of the escalator 1.

[0040] That is, one template may correspond to two or more brackets, and in that one template, the through holes used for marking may be changed for each corresponding bracket. Further, as is clear from the above description, the set of the plurality of templates 20, 25 (processing position specifying device set 50) included in the processing position specifying device 15 of the first embodiment is configured according to the plurality of brackets 7, 8, 9 included in the corresponding escalator 1.

[0041] As described above, the processing position specifying device 15 is used when processing the escalator 1 using one or more reference positions 11 defined in the escalator 1. The processing position specifying device 15 includes a template (main body) 20 that can specify the position of a reference portion 17 disposed at a disposed position 16 based on the reference position 11, and a processing position specifying portion 27 that can specify one or more processing positions 18 in a state where the reference portion 17 is located at the disposed position 16.

[0042] According to the present disclosure, by disposing the reference portion 17 at the reference position 11, one or more processing positions 18 of the escalator 1 can be accurately specified, and marking can be performed on the one or more processing positions 18. Therefore, processing at the one or more processing positions 18 can be performed quickly and accurately, so that displacement of the processing position 18 can be suppressed and the working time can be shortened in new construction work or renewal work. In the first embodiment, the disposed position 16 coincides with the reference position 11, but the disposed position may be a position different from the reference position.

[0043] Further, the processing position specifying device 15 may be configured by a plate-shaped template 20 made of metal or resin, and the template 20 may have one or more through holes 21 that constitute the processing position specifying portion 27. And in a state where the reference portion 17 is located at the disposed position 16, the position overlapping the through hole 21 may include at least a part of the processing position 18.

[0044] According to this configuration, by disposing the template 20 at a predetermined position, one or more processing positions 18 can be specified quickly and accurately. Further, since the template 20 is hard and difficult to break, the handleability during transportation of the processing position specifying device 15 can also be improved. Note that the processing position may have a portion protruding from the position overlapping the through hole in a state where the reference portion is located at the disposed position, and all of the processing positions may be included in the position overlapping the through hole in a state where the reference portion is located at the disposed position.

[0045] Further, the processing position specifying device set 50 according to the present disclosure includes a plurality of templates 20, 25 that are different from each other.

[0046] In general, it is necessary to form a plurality of sets of a plurality of holes having different layouts from each other in the truss 2, and cutting may be performed. Also, the sets of the plurality of holes 14 existing in plurality differ depending on the model of the escalator 1. Therefore, by preparing a processing position specifying device set 50 including a template set composed of a plurality of templates 20 and 25 for each model as in this configuration, it is possible to quickly and accurately mark all or most of the processing positions 18, and all the holes formed in the escalator 1 and all the cutting processes, or most of the holes and most of the cutting processes can be formed quickly and accurately.

[0047] Further, the processing position specifying device set 50 may include a template (hole linearly arranged template) 20 having a plurality of through holes 21 arranged at intervals on a straight line.

[0048] In the truss 2, a longitudinal extending bracket 9 extending in a direction orthogonal to the bottom surface thereof may be attached, and the longitudinal extending bracket 9 may have through holes at intervals in its extending direction. On the other hand, according to this configuration, the processing position specifying device set 50 includes a template 20 having a plurality of through holes 21 arranged at intervals on a straight line. Therefore, by providing a plurality of holes arranged at intervals on a straight line in the truss 2 using the template 20, the longitudinal extending bracket 9 can be easily attached to the truss 2.

[0049] Note that the case where the reference portion 17 of the template 20 is two corners 21a and 21b included in the template 20 has been described. However, the reference portion of the template may not be two corners, may be a portion not included in the template, or may be any portion whose position can be specified in the template. For example, the reference portion of the template may be composed of the center of the first through hole formed in the template and the center of the second through hole.

[0050] Also, the case where the template 20 can be used for machining at a plurality of different locations on the escalator 1 has been described. However, the template constituting the machining position specifying device may be one that can be used only for machining at one location on the escalator, and may be used when machining the escalator using only one reference position defined on the escalator.

[0051] Also, the case where a plurality of machining positions 18 are specified using plate-shaped templates 20, 25 having a plurality of through-holes 21 and made of metal or resin has been described. However, the template may have only one through-hole and may be used to specify only one machining position.

[0052] Also, the case where the machining position 18 is specified by the through-holes 21, 26 using plate-shaped templates 20, 25 made of metal or resin has been described. However, the templates 20, 25 may be those with the machining position marked, and may not have through-holes. Then, the template may be applied based on the position specified by the local truss or the like, a punch mark may be made using the mark on the template, and then machining may be performed with a drill or the like.

[0053] Also, the template may be made of a material that is neither metal nor resin, for example, paper such as cardboard. Also, the case where the machining on the truss 2 is hole drilling on the side wall portions 10a, 10b of the truss 2 has been described. However, as described above, the template may be used for cutting. In this case, the template may have one or more slits (elongated holes), and the cutting position may be specified by the slits.

[0054] (Second Embodiment) FIG. 4 is a block diagram showing the main configuration of the machining position specifying device 115 according to the second embodiment. As shown in FIG. 4, the machining position specifying device 115 includes a projection device 120, a display unit 122, an operation unit 123, and a control device 124. The display unit 122 is composed of a liquid crystal panel, an organic EL panel, or the like. The operation unit 123 may include keys and buttons, and may be included in a wireless remote control capable of wirelessly transmitting a plurality of signals to the control device 124. It is preferable that the display unit 122 and the operation unit 123 are composed of a touch panel in which a touch sensor and a display are integrated.

[0055] The control device 124 is preferably configured by a computer, for example, a microcomputer, and includes a control unit 125 and a storage unit 126. The control unit 125, that is, the processor, includes, for example, a CPU (Central Processing Unit). The storage unit 126 is composed of a hard disk drive (HDD), a solid state drive (SSD), or the like, and may include a non-volatile memory such as a ROM (Read Only Memory) and a volatile memory such as a RAM (Random Access Memory). The storage unit 126 may be composed of only one storage medium or a plurality of different storage mediums. The CPU reads and executes a program or the like stored in advance in the storage unit. The non-volatile memory stores in advance a control program, a predetermined threshold value, and the like. The volatile memory temporarily stores the read program and processing data.

[0056] The projection device 120 includes a projector. The projection device 120 has a projection unit 121, and the projection unit 121 includes a first projection unit 121a that projects an image on a first side in one direction (a linear direction, for example, the width direction of the truss 2) and a second projection unit 121b that projects an image on a second side opposite to the first side in one direction. Any projection method may be adopted as the projection method of the projector. For example, a liquid crystal method, a DLP (Digital Light Processing (registered trademark)) method, or an LCOS (Liquid crystal on silicon) may be adopted.

[0057] The machining position specifying device 115 includes a base portion 139 (see FIG. 6) placed on a placement surface such as the bottom surface of the truss 2, and a height variation mechanism 127 that varies the heights of the first and second projection portions 121a and 121b with respect to the base portion 139. The height variation mechanism 127 includes a known linear actuator configured by an electric cylinder or the like, and uses the linear actuator to vary the heights of the first and second projection portions 121a and 121b.

[0058] Each of the first projection portion 121a and the second projection portion 121b has a light source and can project an image (machining drawing) under the control of the control device 124. The operation unit 123 includes a machining position display operation unit 123a, a height adjustment operation unit 123b, a bracket selection unit 123c, a first projection start operation unit 123d, a second projection start operation unit 123e, a first projection end operation unit 123f, a second projection end operation unit 123g, and a machining information deletion operation unit 123h. Further, in the storage unit 126 of the control device 124, information on the shape of each bracket and position information on the machining position in each bracket are stored in advance.

[0059] When a person operates the machining position display operation unit 123a, the display unit 122 may display, in a linked state, one or more truss extension direction positions (positions in the extension direction of the truss 2 on the bottom surface of the truss 2), a projection unit (at least one of the first projection unit 121a and the second projection unit 121b) that operates at each truss extension direction position, the heights of the projection units 121a and 121b that operate at each truss extension direction position, and information on the bracket corresponding to the machining drawing projected by the projection units 121a and 121b (hereinafter, each of the linked information is referred to as machining information).

[0060] The display unit 122 may display the plurality of associated processing information in order from the upper side to the lower side of the screen, for example, based on the data of the truss extending direction position close to one end in the passenger transportation direction of the escalator 1. When performing a plurality of processes with different heights at the same position in the truss extending direction, it may be displayed from the upper side to the lower side of the screen in order from the processing position with the lower height. In the case of symmetric processing, it may be displayed from the upper side to the lower side of the screen in the order of the first projection unit 121a and the second projection unit 121b.

[0061] In the present embodiment, the first projection unit 121a and the second projection unit 121b project the processing drawing in opposite directions to each other, and the first projection unit 121a and the second projection unit 121b can only be adjusted to the same height. Here, when performing different processes on the side wall portions 10a and 10b on both sides of the truss 2 at the same truss extending direction position of the processing position specifying device 115, for example, in addition to performing projection in the order of the processing information displayed from the upper side on the screen of the display unit 122, after performing one or more projections using the first projection unit 121a, one or more projections using the second projection unit 121b may be performed. In the storage unit 126 of the control device 124, data of the mounting position for each bracket is stored in advance for all different brackets. The display by the display unit 122 is executed based on the data of the mounting position for each bracket.

[0062] Based on the display, a person moves the processing position specifying device 115 to the position in the extending direction of the truss 2 where processing is to be performed, and operates the height adjustment operation unit 123b at that position to appropriately operate the linear actuator and adjust the heights of the projection units 121a and 121b. Further, a person can select the processing drawing projected by the projection units 121a and 121b. This is executed by selecting the bracket corresponding to the processing drawing (the bracket to be attached with that processing drawing) using the bracket selection unit 123c.

[0063] After adjusting the height of the projection part at each truss extending direction position, the user operates the projection start operation parts 123d and 123e of the projection parts 121a and 121b for projection. Then, the processing drawing is projected onto the side surface of the side wall part 10 from the corresponding projection parts 121a and 121b. FIG. 5 is a plan view showing an example of the projection image 177 of the processing drawing projected onto the side surface of the side wall part 10, and is a plan view showing the projection image 177 corresponding to FIG. 2(a).

[0064] Based on this projection image 177, the user can perform marking on the processing position 118. When the marking is completed, the user operates the projection end operation parts 123f and 123g of the corresponding projection parts 121a and 121b to end the projection of the corresponding projection parts 121a and 121b. Then, the user operates the processing information erasing operation part 123h to erase the display of the processing information that has been marked and is displayed on the display part 122. When this erasing is completed, the user refers to the above display again and moves at least one of the projection parts 121a and 121b to the position corresponding to the next processing position to perform the next projection. By repeating this procedure, all processing is performed. The processing may include, in addition to drilling, the above-mentioned cutting process.

[0065] Note that the display part 122 may be able to display only a predetermined number of the displays of the processing information. After the user performs marking for a predetermined number (the predetermined number is any natural number) corresponding to the predetermined number of the processing information, the user may be able to display the next predetermined number of the processing information on the display part 122. Further, the display part 122 may perform a display that allows the user to recognize that it is the last processing information. This display may be performed, for example, by displaying the last processing information in a colored (for example, green) manner, or by displaying a notation indicating that it is the last after the last processing information. This notation may be performed, for example, by a display such as (last), or by a display surrounding the last character with parentheses.

[0066] FIG. 6 is a schematic plan view when looking at a machining position specifying device 115 that projects simultaneously onto both side wall portions 10a and 10b on both sides of the truss 2 from above in a direction perpendicular to the bottom surface of the truss inside the truss 2. In FIG. 6, actually, the inside of the side wall portions 10a and 10b that cannot be visually recognized is shown in cross section. As shown in FIG. 6, the machining position specifying device 115 is arranged at the center position in the width direction of the truss 2, and the width direction distance of the truss 2 from the first projection portion 121a to the first side wall portion 10a is substantially the same as the width direction distance of the truss 2 from the second projection portion 121b to the second side wall portion 10b. In the state shown in FIG. 6, the first projection portion 121a and the second projection portion 121b are present at the same vertical position. Also, in the state shown in FIG. 6, the first projection portion 121a and the second projection portion 121b are arranged substantially symmetrically with respect to a plane that extends vertically through the center in the width direction of the truss 2 in a partial region 2a in the extending direction of the truss 2, that is, a plane P that bisects the region 2a in the width direction. From this, the projection portion 121 can project a plurality of machining positions that are substantially symmetric with respect to the plane P that bisects the region 2a in the width direction of the truss 2.

[0067] As described above, the machining of the side walls of the truss 2 may include symmetric machining that is the same on both sides in the width direction. According to this configuration, since the projection portion 121 can project a plurality of machining positions that are substantially symmetric with respect to the plane P that bisects the region 2a in the width direction of the truss 2, for the same symmetric machining on the side wall portions 10a and 10b on both sides in the width direction of the truss 2, machining can be performed simultaneously on both sides in the width direction. Therefore, the marking of the machining positions of the first side wall portion 10a and the second side wall portion 10b can be performed more quickly.

[0068] FIG. 7 is a flowchart for explaining an example of a procedure for marking a plurality of machining positions using the machining position specifying device 115. Referring to FIG. 7, first, in step S1, the machining position display operation unit 123a is operated. Then, in step S2, the display unit 122 displays a plurality of machining information. Here, each machining information is information in which the truss extending direction position, the projection units 121a and 121b operated at each truss extending direction position, the height of the projection units 121a and 121b operated at each truss extending direction position, and the information of the bracket corresponding to the machining drawing projected by the projection units 121a and 121b are linked.

[0069] The display unit 122 displays the linked plurality of machining information, for example, in order from the upper side to the lower side of the screen based on the data of the truss extending direction position close to one end in the passenger transportation direction of the escalator 1. When performing a plurality of machinings at the same truss extending direction position but different heights, the display is performed in order from the machining position with the lower height from the upper side to the lower side of the screen. Also, in the case of symmetric machining where the truss extending direction position and the height are the same, the machining information regarding the first projection unit 121a is displayed above the machining information regarding the first projection unit 121a on the screen.

[0070] In the subsequent step S3, a person moves the projection units 121a and 121b to a position where the machining position corresponding to the machining information can be projected based on the machining information described at the top in the display unit 122. Here, in the case of symmetric machining where machining is performed simultaneously on the side wall portions 10a and 10b on both sides, the projection units 121a and 121b are moved based on the machining information described at the top and the machining information described second from the top.

[0071] In the case of this embodiment, since the relative position of the second projection unit 121b with respect to the first projection unit 121a cannot vary, when the position of the first projection unit 121a is determined, the position of the second projection unit 121b is also uniquely determined. Further, in this case, the reference position is, for example, the center of two machining positions (for example, the centers of two holes) included in the wall surface of one side wall portion 10a, or the center of three machining positions (for example, the centers of three holes). Further, the arrangement position 116 (see FIG. 6) is, for example, a position where two corner portions 139a, 139b of the base portion 139 overlap at two specific positions on the truss bottom surface when viewed from a direction perpendicular to the truss bottom surface, and the height at which the center of the lens surface of the first projection unit 121a is located is a specific height. Further, the reference portion 117 (see FIG. 6) is composed of two corner portions 139a, 139b of the base portion 139 and the center of the lens surface of the first projection unit 121a. Further, the main body of the machining position specifying device 115 that can specify the reference portion 117 is constituted by the machining position specifying device itself.

[0072] Subsequently, in step S4, a machining drawing is selected by operating the bracket selection unit 123c, and then, in step S5, projection is performed by the corresponding projection units 121a, 121b based on the projection unit information linked to the machining information. Here, when performing the above-described symmetric machining on the side wall portions 10a, 10b on both sides, the two projection units 121a, 121b project the machining drawing onto the side wall portions 10a, 10b on both sides simultaneously. Subsequently, in step S6, a person marks the machining position based on the machining image projected by the projection units 121a, 121b, and then, in step S7, the projection of the projection units 121a, 121b that are projecting is terminated.

[0073] Next, in step S8, a person refers to the display unit 122 to determine whether the marking of all the machining positions has been completed. If a negative determination is made in step S8, then in step S9, an operation is performed to erase from the display the machining information corresponding to the machining position for which the marking has been completed among the machining information displayed on the display unit 122 by operating the operation unit 123. Here, when symmetric machining is performed on the side wall portions 10a and 10b on both sides in the width direction of the truss 2, two pieces of machining information, that is, the machining information described at the topmost and the machining information described second from the top, are erased. When step S9 ends, steps S3 and subsequent steps are repeated. On the other hand, if an affirmative determination is made in step S8, the marking of the machining positions is completed.

[0074] As described above, the machining position specifying device 115 according to one embodiment may include a projection unit 121 that projects one or more machining positions. Inside the truss 2 is dim. Therefore, a machining drawing can be projected by a projection device 120 including a projection unit 121 such as a projector, and the machining position can be projected.

[0075] According to this configuration, by storing data on the layout of a plurality of sets of a plurality of holes and data on the machining positions in the storage unit 126 of the machining position specifying device 115, and while moving the projection device 120, at each stationary position (each projection position), by appropriately projecting the formation positions of one or more appropriately selected holes and one or more cutting locations, the machining positions of all the holes, all the cutting locations, or most of the holes and most of the cutting locations can be quickly and accurately specified and marked. Therefore, all the holes and all the cutting locations, or most of the holes and most of the cutting locations to be formed in the escalator 1 can be quickly and accurately formed.

[0076] Also, by simply swapping data or appropriately selecting one set of data corresponding to the model for which construction is to be performed from a plurality of sets of data, it is possible to easily correspond to a new model or a large number of models, and a machining position specifying device 115 with excellent versatility can be realized. Furthermore, since there is no need to produce items such as templates, the machining of the passenger conveyor can be performed at low cost.

[0077] In addition, in a state where the reference portion 117 is disposed at the disposition position 116, the projection portion 121 may project a plurality of machining positions that are substantially plane-symmetric with respect to a plane P that substantially bisects at least a partial region 2a in the extending direction of the truss 2 in the width direction of the truss 2.

[0078] As described above, the machining of the side walls of the truss 2 may include machining that is the same on both sides in the width direction. According to this configuration, since the projection portion 121 can project a plurality of machining positions that are substantially plane-symmetric with respect to the plane P that substantially bisects the region 2a in the width direction of the truss 2, for the same machining on the side wall portions 10a and 10b on both sides in the width direction of the truss 2, machining can be performed simultaneously on both sides in the width direction. Therefore, the marking of the machining positions of the first side wall portion 10a and the second side wall portion 10b can be performed more quickly.

[0079] Further, the machining method of the passenger conveyor according to the present disclosure is a passenger conveyor machining method using a machining position specifying device 115 in which the projection portion 121 can project a plurality of machining positions that are substantially plane-symmetric with respect to a plane P that substantially bisects the region 2a in the width direction of the truss 2. Further, the machining method of the passenger conveyor according to the present disclosure includes a projection step of projecting a plurality of machining positions that are substantially plane-symmetric with respect to a plane P that substantially bisects the region 2a in the width direction onto the projection portion 121 in a state where the reference portion 117 is disposed at the disposition position 116, and a marking step of applying a marking that enables each machining position to be specified to the plurality of projected machining positions.

[0080] According to the present disclosure, for the same symmetric machining on the side wall portions 10a and 10b on both sides in the width direction of the truss 2, machining can be performed simultaneously on both sides in the width direction. Therefore, the marking of the machining positions of the first side wall portion 10a and the second side wall portion 10b can be performed more quickly.

[0081] Note that the present disclosure is not limited to the above-described embodiments and their modifications, and various improvements and changes are possible within the scope of the matters described in the claims of the present application and their equivalent scope.

[0082] For example, since the template that constitutes the machining position specifying device of the first embodiment is often used in dim areas, it is preferable that a fluorescent paint is applied to the outer surface. Further, one or more magnets may be fixed (attached) to the surface of the template that abuts against the wall surface. And when the wall surface is made of metal, a configuration may be adopted in which the template is fixed to the wall surface by the magnetic force of the magnet. By doing so, displacement of the template can be suppressed, and furthermore, marking of the machining position can be performed with high precision. Also, when a magnet is fixed to the template, marking can be performed by one person, so marking can be performed more efficiently.

[0083] Also, in the machining position specifying device of the second embodiment, the projection unit may be supported by a tripod. Further, in the second embodiment, the case where the machining position specifying device 115 has two projection units 121a and 121b has been described. However, the machining position specifying device may have only one projection unit, and by setting the orientation of the projection unit when projecting the machining drawing on the first side wall portion 10a on one side in the width direction of the truss 2 to be opposite to the orientation of the projection unit when projecting the machining drawing on the second side wall portion 10b on the other side in the width direction of the truss 2, marking of the side wall portions 10a and 10b on both sides in the width direction of the truss 2 may be performed.

[0084] Also, the machining position specifying device 115 of the second embodiment may be configured as an integrated and inseparable device. Or, the machining position specifying device 115 of the second embodiment may include a mechanism in which a projector and an information terminal (for example, a personal computer, a tablet, a mobile phone (smartphone), etc.) installed with a dedicated application for executing the above-described operations are connected by a cable.

[0085] As described above, by using a template as in the first embodiment, the processing position can be grasped instantaneously, so that the working time can be significantly shortened, and dimensional reading errors and measurement errors can be reduced. Further, by using a projector (projection device) instead of a template as in the second embodiment, not only can the material cost of the templates, which generally requires multiple sheets, be reduced, but also the data can be diverted to other objects in data management, and a processing position specifying device with excellent versatility can be constructed. In the method using a projector (projection device), unlike the above-described method, simply attach a point to the position serving as the reference of the truss, and based on that point, adjust the scale of the projector (projection device) installed at a certain distance from the reference to project the processing drawing. Then, the processing drawing may be checked and a punch mark may be made on the truss, and processing may be performed with a drill or the like.
