Description

Processing position specifying device for passenger conveyor, processing position specifying device set, and processing method for passenger conveyor

[0001] The present disclosure relates to a processing position specifying device for a passenger conveyor, for example, a template used to specify a processing position, a projector device that projects the processing position, etc. The present disclosure also relates to a processing position specifying device set configured with a set of multiple templates used to specify a processing position, and a processing method for a passenger conveyor.

[0002] As described in Patent Document 1, in escalator renewal work, support members (brackets) must be attached by screws, which requires drilling holes in the existing truss.

[0003] JP 2012-176810 A

[0004] When renovating an escalator, in order to attach parts with the latest structure to existing trusses and reused parts, it may be necessary to drill holes and cut in more than 200 places on site per unit.

[0005] This requires time-consuming work, as the work involves checking the blueprint in a dark place, measuring the dimensions from the reference, confirming the hole positions, marking with a punch, etc., and then drilling. Furthermore, there is a risk of improper installation of parts due to misreading of dimensions or measurement errors, which can lead to the need to redo the work or change parts. These problems also exist in the construction of new escalators.

[0006] Therefore, an object of the present disclosure is to provide a processing position identification device for a passenger conveyor, a processing position identification device set, and a processing method for a passenger conveyor that can easily suppress misalignment of the processing position and shorten work time during new construction and renewal work.

[0007] In order to solve the above problem, the processing position identification device for a passenger conveyor according to the present disclosure is a processing position identification device used when processing the passenger conveyor using one or more reference positions defined on the passenger conveyor, and comprises a main body capable of identifying the position of a reference part that is placed at a placement position based on the reference positions, and a processing position identification part that can identify one or more processing positions when the reference part is positioned at the placement position.

[0008] According to the present disclosure, by arranging the reference portion at the reference position, it is possible to accurately identify one or more processing positions and apply markings to the one or more processing positions. Therefore, since processing at the one or more processing positions can be easily performed quickly and accurately, it is easy to suppress deviation of the processing positions in new construction work and renewal work, and it is easy to shorten the work time.

[0009] It may also be configured as a plate-shaped template made of metal or resin, the template having one or more through holes that form the processing position identification portion, and when the reference portion is positioned at the placement position, the position that overlaps with the through holes may include at least a portion of the processing position.

[0010] In addition, the processing position may have a portion that extends beyond the position that overlaps with the through hole when the reference portion is located at the placement position, or the entire processing position may be included in a position that overlaps with the through hole when the reference portion is located at the placement position.

[0011] According to this configuration, one or more processing positions can be quickly and accurately identified simply by placing the template in a predetermined position. In addition, since the template is hard and not easily damaged, it can be easily handled during transportation, etc.

[0012] Furthermore, 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, a truss requires the formation of multiple sets of holes with different layouts, and cutting processes may be performed. Furthermore, the multiple sets of holes and cutting processes vary depending on the model of the passenger conveyor. Therefore, by preparing a template set consisting of multiple templates for each model, as in the present configuration, it is possible to quickly and accurately mark all or the majority of processing positions. Therefore, it is possible to quickly and accurately form all holes and all cutting processes to be formed in the passenger conveyor, or to quickly and accurately form the majority of holes and the majority of cutting processes.

[0014] The machining position specifying device set may also include a hole linear arrangement template having a plurality of the through holes arranged at intervals in a straight line.

[0015] A truss may be fitted with a vertically extending member (vertically extending bracket) extending perpendicular to its bottom surface, and the vertically extending member may have holes spaced apart in its extension direction. In contrast, according to this configuration, the machining position specifying device set includes a hole alignment template having a plurality of through holes spaced apart in a straight line. Therefore, by using the hole alignment template to form a plurality of holes in the truss that are spaced apart in a straight line, the vertically extending member can be easily attached to the truss.

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

[0017] The inside of the truss is dimly lit, so 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, layout data and processing position data for multiple hole sets that exist are stored in the memory unit of the processing position specifying device, and the projection device is moved while appropriately projecting the formation positions of one or more appropriately selected holes or one or more cutting positions at each stationary position (each projection position), thereby making it possible to quickly and accurately specify and mark the processing positions of all holes or all cutting positions, or the majority of holes or the majority of cutting positions. Thus, all holes or all cutting positions, or the majority of holes or the majority of cutting positions to be formed on the passenger conveyor, can be quickly and accurately formed.

[0019] In addition, simply by replacing the data or appropriately selecting one data set from multiple data sets that corresponds to the model to be worked on, it is possible to easily accommodate new models or multiple models, thereby realizing a highly versatile processing position specifying device.Furthermore, since there is no need to create anything such as a template, processing of passenger conveyors can be done inexpensively.

[0020] Furthermore, when the reference part is positioned at the placement position, the projection part may be capable of projecting a plurality of processing positions that are approximately plane-symmetric with respect to a plane that approximately bisects at least a portion of the area in the extension direction of the truss in the width direction of the truss.

[0021] The processing of the side walls of a truss may include processing that is the same on both sides of the truss in the width direction. With this configuration, the projection unit can project multiple processing positions that are approximately symmetrical with respect to a plane that approximately bisects the above area in the width direction of the truss, so that the same processing on both side walls of the truss in the width direction can be performed simultaneously on both sides of the width direction. Therefore, marking of processing positions on one side wall and the other side wall can be performed more quickly.

[0022] In addition, the processing method for a passenger conveyor according to the present disclosure is a processing method for a passenger conveyor using the processing position identification device, in which the projection unit is capable of projecting a plurality of processing positions that are approximately plane-symmetrical with respect to a plane that approximately bisects the area in the width direction of the truss, and includes a projection step in which, with the reference unit placed at the placement position, the projection unit projects a plurality of processing positions that are approximately plane-symmetrical with respect to a plane that approximately bisects the area in the width direction, and a marking step in which markings are applied to the projected processing positions so that each of the processing positions can be identified.

[0023] According to the present disclosure, simultaneous processing of the same processing on both sidewalls in the width direction of the truss is possible, thereby enabling faster marking of processing positions on one sidewall and the other sidewall.

[0024] According to the processing position specifying device for a passenger conveyor, the processing position specifying device set, and the processing method for a passenger conveyor of the present disclosure, it is possible to suppress deviation of the processing position and shorten the working time.

[0026] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that, when multiple embodiments or variations are included below, it is anticipated from the beginning that new embodiments can be constructed by appropriately combining their characteristic features. In the following examples, the same components are designated by the same reference numerals in the drawings, and redundant explanations will be omitted. The drawings include schematic diagrams, and the dimensional ratios of the length, width, height, etc. of each component between different drawings do not necessarily match. Among the components described below, components not recited in the independent claims representing the highest concepts are optional components and not essential components.

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

[0028] Figure 1 is a perspective view showing the inside of truss 2 of escalator 1 currently undergoing renovation work. Escalator 1 is equipped with drive roller rails 4a, 4b, 5a, and 5b that guide drive rollers located on both the left and right sides of the step width direction from both the top and bottom in the vertical direction, and driven roller rails 6a and 6b that guide driven rollers located on both the left and right sides of the step width direction. Escalator 1 also includes a drive unit located at the top, an upper sprocket that receives power from the drive unit via a drive chain, a lower sprocket that circulates the steps between itself and the upper sprocket, and a handrail drive device that receives power from the upper sprocket and applies force in the direction of movement to the moving handrail.

[0029] 1 , in escalator 1, a variety of brackets 7, 8, and 9 are attached to side wall portions 10 and the like of truss 2 in order to secure these devices, components, and the like to truss 2. The variety of brackets 7, 8, and 9 may include a plurality of vertically extending brackets 9 that are arranged at predetermined intervals in the extension direction of truss 2 and are attached to side wall portions 10 of truss 2 so as to extend in a direction perpendicular to the bottom surface of truss 2. Alternatively, vertically extending bracket 9 may only have a plurality of through holes (not shown) positioned in a straight line at intervals in the extension direction, and may be fixed to side wall portions 10 of truss 2 using the plurality of through holes.

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

[0031] First Embodiment Next, we will explain a processing position specifying device 15 according to a first embodiment of the present disclosure, which is used to specify a processing position when processing an escalator 1. Fig. 2(a) is a plan view of a template 20 constituting the processing position specifying device 15 of the first embodiment, as viewed from one side in the thickness direction, and Fig. 2(b) is a plan view showing one reference area 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 alignment template and is used to identify the positions of multiple holes to be provided in the side walls 10a and 10b of the truss 2 in order to secure the vertically extending bracket 9 to the truss 2. The template 20 is a plate member made of metal or resin. As shown in FIG. 2 , both surfaces of the template 20 in the thickness direction have an elongated rectangular shape. The template 20 has multiple through holes 21 spaced apart in a straight line in the longitudinal direction (the longitudinal direction of both surfaces). Each through hole 21 has, for example, a cylindrical shape. Note that in the template 20 shown in FIG. 2( a), all of the through holes 21 are positioned in a straight line, but the hole alignment template may have both multiple through holes positioned in a straight line and one or more other through holes. Furthermore, the planar shape of the through holes is not limited to a circular shape and may be any shape.

[0033] Machining using the template 20 is performed, for example, as follows. The reference area 19 surrounded by a dotted line in FIG. 2( b) has a planar shape that is approximately the same as the planar shape of the corresponding template 20, and in this embodiment, has a rectangular planar shape. First, a state is established in which a first corner 22 a (the upper left corner in FIG. 2( a)) of the four corners 22 of the template 20 coincides with the corresponding first corner 19 a (the upper left corner in FIG. 2( b)) in the reference area 19, a second corner 22 b (the lower right corner in FIG. 2( a)) of the template 20 coincides with the corresponding second corner 19 b (the lower right corner in FIG. 2( b)) in the reference area 19, and one side surface in the thickness direction of the template 20 abuts against the wall surface of the side wall portion 10 of the truss 2. The first corner 19 a and the second corner 19 b are an example of a reference position 11 for one reference area 19 and also an example of a placement position 16 , and the first corner 22 a and the second corner 22 b are an example of a reference portion 17 .

[0034] Here, each reference position 11 of the escalator 1 is determined, for example, as follows: Positional information of a set of holes 14, for which a plurality of processing positions 18 (see FIG. 2(b)) are identified using the template 20, is recorded on the design drawing, and there is a one-to-one correspondence between the positions of the holes on the design drawing and the corresponding positions at which the holes 14 are formed in the truss 2. Therefore, the positions of the sets of holes 14 on the truss 2, and therefore the reference position 11 (composed of two corners 19a, 19b in this embodiment) that can be identified by the positions of the sets of holes 14, are uniquely determined based on the positional information of the corresponding holes on the design drawing.

[0035] Furthermore, the relative positions of the centers of the remaining holes 14 with respect to the center of one hole 14 among the plurality of holes 14 for which the machining positions 18 of the truss 2 are identified using the template 20 coincide with the relative positions of the centers of the remaining through holes 21 with respect to the center of one through hole 21 among the plurality of through holes 21 provided in the template 20. Therefore, by placing the reference portion 17 of the template 20 at the arrangement position 16 based on the reference position 11, it is possible to accurately and quickly identify the formation positions of the plurality of holes 14 corresponding to the plurality of through holes 21. The template 20 is an example of a main body of the machining position identifying device 15, the plurality of holes 14 (all of the holes 14) are an example of one or more machining positions, and the plurality of through holes 21 (all of the through holes 21) provided in the template 20 are an example of a machining position identifying unit 27.

[0036] Once the two corners 19 a, 19 b of the template 20 have been placed at the reference position 11 on the side wall portion 10 of the truss 2, marking is then performed. This marking is performed, for example, by applying paint or marking with a marker or the like at positions corresponding to each through hole 21 on the template 20 from the side opposite the contact surface that contacts the truss 2. Thereafter, by forming predetermined holes in the truss 2 with a drill or the like at the marked positions, multiple holes 14 for attaching the vertically extending brackets 9 corresponding to one of the reference positions 11 can be accurately formed in the truss 2.

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

[0038] Escalator 1 includes a plurality of different brackets 7, 8, and 9. Just as template 20 was a template for mounting bracket 9, a corresponding template for mounting each bracket 7, 8, and 9 can be prepared. As is clear from the above explanation, the positional relationship of the plurality of through holes (centers of the through holes) formed in each bracket 7, 8, and 9 matches the positional relationship of the plurality of through holes 21 (centers of the through holes 21) formed in the corresponding template 20, and also matches the positional relationship of the plurality of holes 14 (centers of the holes 14) formed in truss 2 for mounting each bracket 7, 8, and 9 to 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, and 9 of the escalator 1. In addition to the template 20, the processing position specifying device set 50 may also include a template 25, the plan view of one side in the thickness direction of which is shown in FIG. 3. The plurality of through holes 26 formed in the template 25 may include through holes 26a arranged in a matrix. In addition to the I-shaped template 20 and the L-shaped template 25, the processing position specifying device set 50 may also include U-shaped or H-shaped templates. The plurality of brackets 7, 8, and 9 for which corresponding templates 20 exist 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 the through holes used for marking in that one template may be different for each corresponding bracket. Also, as is clear from the above description, the set of multiple templates 20, 25 (processing position specifying device set 50) provided in the processing position specifying device 15 of the first embodiment is configured according to the multiple brackets 7, 8, 9 provided 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 on the escalator 1. The processing position specifying device 15 includes a template (main body) 20 that can specify the position of the reference part 17 that is to be placed at the placement position 16 based on the reference position 11, and a processing position specifying unit 27 that can specify one or more processing positions 18 when the reference part 17 is located at the placement position 16.

[0042] According to the present disclosure, by arranging the reference portion 17 at the reference position 11, it is possible to accurately identify one or more processing positions 18 of the escalator 1 and apply markings to the one or more processing positions 18. Therefore, processing at the one or more processing positions 18 can be performed quickly and accurately, which makes it possible to prevent deviation of the processing positions 18 in new construction or renewal construction, and also shortens work time. Note that, although the placement position 16 coincides with the reference position 11 in the first embodiment, the placement position may be a position different from the reference position.

[0043] Furthermore, the processing position specifying device 15 may be configured with a plate-shaped template 20 made of metal or resin, and the template 20 may have one or more through holes 21 that form the processing position specifying portion 27. Then, when the reference portion 17 is located at the arrangement position 16, a position overlapping with the through hole 21 may include at least a part of the processing position 18.

[0044] According to this configuration, by placing the template 20 at a predetermined position, it is possible to quickly and accurately identify one or more processing positions 18. Furthermore, since the template 20 is hard and not easily broken, it is possible to improve the handling properties of the processing position identifying device 15 during transportation, etc. Note that the processing position may have a portion that extends beyond the position that overlaps with the through-hole when the reference portion is located at the placement position, or the entire processing position may be included in the position that overlaps with the through-hole when the reference portion is located at the placement position.

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

[0046] Generally, it is necessary to form multiple sets of holes 14 with different layouts in the truss 2, and cutting may be performed. The sets of holes 14 that exist vary depending on the model of the escalator 1. Therefore, by preparing a processing position specifying device set 50 including a template set made up of multiple templates 20, 25 for each model, as in the present configuration, it is possible to quickly and accurately mark all or the majority of processing positions 18, and to quickly and accurately form all or the majority of the holes and cutting processes to be formed in the escalator 1.

[0047] The machining position specifying device set 50 may also include a template (hole linear arrangement template) 20 having a plurality of through holes 21 arranged at intervals in a straight line.

[0048] A vertically extending bracket 9 extending in a direction perpendicular to the bottom surface of the truss 2 may be attached to the truss 2, and the vertically extending bracket 9 may have through holes spaced apart in the extension direction. In contrast, according to the present configuration, the processing position specifying device set 50 includes a template 20 having a plurality of through holes 21 spaced apart in a straight line. Therefore, by using the template 20 to form a plurality of holes spaced apart in a straight line in the truss 2, the vertically extending bracket 9 can be easily attached to the truss 2.

[0049] In the above description, the reference portions 17 of the template 20 are the two corners 21 a, 21 b included in the template 20. However, the reference portions of the template do not have to be the two corners, may be a portion not included in the template, or may be any portion of the template whose position can be identified. For example, the reference portions of the template may be formed by the centers of the first and second through holes formed in the template.

[0050] Also, the above description has been given of a case where the template 20 can be used to process a plurality of different locations on the escalator 1. However, the template constituting the processing position specifying device may be one that can be used to process only one location on the escalator, or may be used when processing the escalator using only one reference position that is determined on the escalator.

[0051] In addition, the case has been described in which a plurality of processing positions 18 are identified using plate-shaped templates 20, 25 made of metal or resin and having a plurality of through holes 21. However, the template may have only one through hole and may be used to identify only one processing position.

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

[0053] The template may also be made of a material other than metal or resin, for example, cardboard or other paper. The above description also covers the case where the processing of the truss 2 involves drilling holes in the side walls 10a and 10b of the truss 2. However, as described above, the template may also be used for cutting. In this case, the template may have one or more slits (long 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 a processing position specifying device 115 according to a second embodiment. As shown in Fig. 4, the processing 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 configured with a liquid crystal panel, an organic EL panel, or the like. The operation unit 123 may include keys and buttons, or may be included in a wireless remote control that can wirelessly transmit multiple signals to the control device 124. It is preferable that the display unit 122 and the operation unit 123 are configured with a touch panel in which a touch sensor and a display are integrated.

[0055] The control device 124 is preferably configured as a computer, for example, a microcomputer, and includes a control unit 125 and a memory unit 126. The control unit 125, i.e., the processor, includes, for example, a CPU (Central Processing Unit). The memory unit 126 is configured as 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) or a volatile memory such as a RAM (Random Access Memory). The memory unit 126 may be configured as a single storage medium or as multiple different storage media. The CPU reads and executes programs and the like stored in the memory unit. The non-volatile memory pre-stores control programs, predetermined thresholds, and the like. The volatile memory temporarily stores the read programs and processing data.

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

[0057] The processing position specifying device 115 includes a base 139 (see FIG. 6) that is placed on a support surface such as the bottom surface of the truss 2, and a height variation mechanism 127 that varies the height of the first and second projection units 121a, 121b relative to the base 139. The height variation mechanism 127 includes a known linear actuator constituted by an electric cylinder or the like, and varies the height of the first and second projection units 121a, 121b using the linear actuator.

[0058] Each of the first projection unit 121a and the second projection unit 121b has a light source and is capable of projecting an image (processing drawing) under the control of the control device 124. The operation unit 123 includes a processing 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 processing information deletion operation unit 123h. In addition, the memory unit 126 of the control device 124 stores in advance information on the shape of each bracket and position information on the processing position on each bracket.

[0059] When a person operates the processing position display operation unit 123a, the display unit 122 may display one or more truss extension direction positions (the extension direction positions of the truss 2 on the bottom surface of the truss 2), the projection units (at least one of the first projection unit 121a and the second projection unit 121b) to be operated at each truss extension direction position, the heights of the projection units 121a, 121b to be operated at each truss extension direction position, and bracket information corresponding to the processing drawings projected by the projection units 121a, 121b, all linked together (hereinafter, each of this linked information will be referred to as processing information).

[0060] The display unit 122 may display the linked multiple pieces of processing information from the top to the bottom of the screen in order, for example, starting with the data for the truss extension direction position closest to one end of the passenger transport direction of the escalator 1. Note that when multiple processing operations of different heights are performed at the same position in the truss extension direction, the processing positions with the lowest heights may be displayed from the top to the bottom of the screen in order, and in the case of symmetrical processing, the first projection unit 121a and the second projection unit 121b may be displayed from the top to the bottom of the screen in that order.

[0061] In this embodiment, the first projection unit 121a and the second projection unit 121b project machining drawings in opposite directions, and the first projection unit 121a and the second projection unit 121b can only be adjusted to the same height. Here, when different machining operations are performed on the side walls 10a and 10b on both sides of the truss 2 at the same truss extension direction position of the machining position identification device 115, the machining information may be projected in the order displayed on the display unit 122 from top to bottom. Alternatively, one or more projections may be performed using the first projection unit 121a, followed by one or more projections using the second projection unit 121b. The memory unit 126 of the control device 124 stores data on the mounting positions of all the different brackets. The display unit 122 displays the information based on the mounting position data for each bracket.

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

[0063] After adjusting the projection unit height at each truss extension direction position, the person operates the projection start operation units 123d, 123e of the projection units 121a, 121b that will perform the projection. Then, the processing drawing is projected from the corresponding projection unit 121a, 121b onto the side surface of the side wall unit 10. Figure 5 is a plan view showing an example of a projection image 177 of the processing drawing projected onto the side surface of the side wall unit 10, and is a plan view showing the projection image 177 corresponding to Figure 2(a).

[0064] The person can mark the processing position 118 based on this projected image 177. When the marking is completed, the person operates the projection end operation unit 123f, 123g of the corresponding projection unit 121a, 121b to end the projection of the corresponding projection unit 121a, 121b. Thereafter, the person operates the processing information deletion operation unit 123h to erase the display of the processing information displayed on the display unit 122 for which marking has been completed. When this erasure is completed, the person again refers to the display and moves at least one of the projection units 121a, 121b to a position corresponding to the next processing position, and performs the next projection. By repeating this procedure, all processing is completed. Processing may include the above-mentioned cutting process in addition to hole drilling.

[0065] The display unit 122 may be capable of displaying only a predetermined number of pieces of processing information, and after a person has marked a predetermined number of pieces of processing information (the predetermined number being any natural number) corresponding to the predetermined number of pieces of processing information, the display unit 122 may be capable of displaying the next predetermined number of pieces of processing information. The display unit 122 may also display information that allows a person to recognize that the processing information is the last. This display may be performed, for example, by displaying the last processing information in color (e.g., green), or by displaying a notation indicating that the last processing information is displayed after the last processing information. This notation may be performed, for example, by displaying "(last)" or by enclosing the last character in parentheses.

[0066] FIG. 6 is a schematic plan view of the machining position specifying device 115, which is simultaneously projecting onto both side walls 10a and 10b of the truss 2, as viewed from above in a direction perpendicular to the bottom surface of the truss 2. Note that FIG. 6 also shows a cross-section of the interior of the side walls 10a and 10b, which are not actually visible. As shown in FIG. 6, the machining position specifying device 115 is disposed at the center position in the width direction of the truss 2, and the widthwise distance of the truss 2 from the first projection unit 121a to the first side wall 10a is approximately the same as the widthwise distance of the truss 2 from the second projection unit 121b to the second side wall 10b. In the state shown in FIG. 6, the first projection unit 121a and the second projection unit 121b are located at the same vertical position. 6, the first projection unit 121a and the second projection unit 121b are arranged in a plane that extends vertically through the center of the width direction of the truss 2 in a region 2a that is a part of the extension direction of the truss 2, i.e., in a plane P that bisects the region 2a in the width direction. This makes it possible for the projection unit 121 to project a plurality of processing positions that are in a plane symmetry with respect to the plane P that bisects the region 2a in the width direction of the truss 2.

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

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

[0069] The display unit 122 displays the linked multiple pieces of processing information from top to bottom of the screen in order, for example, starting with the data for the truss extension direction position closest to one end of the passenger transport direction of the escalator 1, and when multiple processing operations are performed at the same truss extension direction position but different heights, the processing positions with the lowest heights are displayed from top to bottom of the screen in order. Also, when symmetrical processing is performed and the truss extension direction position and height are the same, the processing information related to the first projection unit 121a is displayed higher on the screen than the processing information related to the second projection unit 121a.

[0070] In the next step S3, a person moves the projection units 121a and 121b to positions where they can project the processing position corresponding to the processing information written at the top of the display unit 122. Here, in the case of symmetric processing in which processing is performed simultaneously on both side wall units 10a and 10b, the projection units 121a and 121b are moved based on the processing information written at the top and the processing information written second highest.

[0071] In this embodiment, the relative position of the second projection unit 121b with respect to the first projection unit 121a is immutable, so once the position of the first projection unit 121a is determined, the position of the second projection unit 121b is also uniquely determined. In this case, the reference position is, for example, the center of two processing positions (e.g., the center of two holes) or the center of three processing positions (e.g., the center of three holes) included in the wall surface of one of the side walls 10a. The placement position 116 (see FIG. 6) is, for example, a position where the two corners 139a and 139b of the base unit 139 overlap two specific positions on the truss bottom surface when viewed perpendicularly to the truss bottom surface, and where the center of the lens surface of the first projection unit 121a is located at a specific height. The reference unit 117 (see FIG. 6) is composed of the two corners 139a and 139b of the base unit 139 and the center of the lens surface of the first projection unit 121a. The main body of the processing position specifying device 115 that can specify the reference portion 117 is configured by the processing position specifying device itself.

[0072] In the next step S4, a processing 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 processing information. Here, when the above-mentioned symmetric processing is performed on both side wall portions 10a, 10b, the two projection units 121a, 121b simultaneously project the processing drawing onto both side wall portions 10a, 10b. In the next step S6, a person marks the processing position based on the processing image projected by the projection units 121a, 121b, and then in step S7, the projection by the projection units 121a, 121b is terminated.

[0073] In the next step S8, a person refers to the display unit 122 to determine whether marking of all processing positions has been completed. If a negative determination is made in step S8, in step S9, an operation is performed by operating the operation unit 123 to erase from the display any processing information displayed on the display unit 122 for which marking of the corresponding processing positions has been completed. Here, if symmetrical processing has been performed on the side wall portions 10a, 10b on both sides of the width direction of the truss 2, two pieces of processing information, i.e., the processing information listed at the top and the processing information listed second highest, are erased. When step S9 is completed, step S3 and subsequent steps are repeated. On the other hand, if a positive determination is made in step S8, marking of processing positions is completed.

[0074] As described above, the processing position specifying device 115 of one embodiment may include a projection unit 121 that projects one or more processing positions. The inside of the truss 2 is dimly lit. Therefore, a processing drawing can be projected by a projection device 120 including a projection unit 121 such as a projector, and the processing positions can be projected.

[0075] According to this configuration, layout data and processing position data for multiple hole sets that exist are stored in the memory unit 126 of the processing position specifying device 115, and the projection device 120 is moved while appropriately projecting the formation positions of one or more appropriately selected holes or one or more cutting positions at each stationary position (each projection position), thereby making it possible to quickly and accurately specify and mark the processing positions of all holes or all cutting positions, or the majority of holes or the majority of cutting positions. Thus, all holes or all cutting positions, or the majority of holes or the majority of cutting positions to be formed in the escalator 1, can be quickly and accurately formed.

[0076] In addition, simply by replacing the data or appropriately selecting one data set from multiple data sets that corresponds to the model to be worked on, it is possible to easily accommodate new models or multiple models, thereby realizing a highly versatile processing position specifying device 115. Furthermore, since there is no need to create anything such as a template, processing of passenger conveyors can be done inexpensively.

[0077] Furthermore, when the reference portion 117 is positioned at the placement position 116, the projection portion 121 may be capable of projecting a plurality of processing positions that are approximately plane-symmetric with respect to a plane P that approximately bisects at least a portion of the area 2a in the extension direction of the truss 2 in the width direction of the truss 2.

[0078] As described above, processing of the side walls of the truss 2 may include processing that is the same on both sides in the width direction. With this configuration, the projection unit 121 can project multiple processing positions that are approximately symmetrical with respect to the plane P that approximately bisects the region 2a in the width direction of the truss 2, so that processing can be performed simultaneously on both sides in the width direction for the same processing on the side walls 10a, 10b on both sides in the width direction of the truss 2. Therefore, marking of processing positions on the first side wall 10a and the second side wall 10b can be performed more quickly.

[0079] The processing method for a passenger conveyor according to the present disclosure is a processing method for a passenger conveyor using a processing position specifying device 115, in which a projection unit 121 can project a plurality of processing positions that are approximately plane-symmetrical with respect to a plane P that approximately bisects the region 2a in the width direction of the truss 2. The processing method for a passenger conveyor according to the present disclosure includes a projection step in which, with a reference unit 117 placed at a placement position 116, the projection unit 121 projects a plurality of processing positions that are approximately plane-symmetrical with respect to a plane P that approximately bisects the region 2a in the width direction, and a marking step in which markings are applied to the plurality of projected processing positions so that each processing position can be identified.

[0080] According to the present disclosure, simultaneous processing can be performed on both widthwise side wall portions 10a, 10b of the truss 2 for the same symmetrical processing. Therefore, marking of processing positions on the first side wall portion 10a and the second side wall portion 10b can be performed more quickly.

[0081] The present disclosure is not limited to the above-described embodiment and its modifications, and various improvements and modifications are possible within the scope of the claims of the present application and their equivalents.

[0082] For example, since the template constituting the machining position identifying device of the first embodiment is often used in dimly lit locations, it is preferable that the outer surface be coated with fluorescent paint. Furthermore, the template may have one or more magnets affixed (fixed) to the surface that abuts against the wall surface. Furthermore, if the wall surface is made of metal, the template may be fixed to the wall surface by the magnetic force of the magnets. This configuration can prevent the template from shifting, and furthermore, allows for highly accurate marking of the machining position. Furthermore, when magnets are fixed to the template, marking can be performed by one person, making marking more efficient.

[0083] In the processing position specifying device of the second embodiment, the projection unit may be supported by a tripod. In the second embodiment, the processing position specifying device 115 has been described as having two projection units 121a and 121b. However, the processing position specifying device may have only one projection unit, and marking may be performed on both side walls 10a and 10b in the width direction of the truss 2 by setting the orientation of the projection unit when projecting the processing diagram onto the first side wall 10a on one side in the width direction of the truss 2 opposite to the orientation of the projection unit when projecting the processing diagram onto the second side wall 10b on the other side in the width direction of the truss 2.

[0084] The processing position specifying device 115 of the second embodiment may be configured as an integrated, inseparable device, or may include a mechanism in which a projector and an information terminal (such as a personal computer, tablet, or mobile phone (smartphone)) on which a dedicated application for executing the above-mentioned operation is installed are connected by a cable.

[0085] As described above, using a template as in the first embodiment allows for instantaneous identification of the processing position, significantly shortening work time and reducing errors in reading dimensions and measuring. Furthermore, using a projector (projection device) instead of a template as in the second embodiment not only reduces the material costs of templates, which are typically required in multiple copies, but also allows for data management and reuse for other projects, resulting in a highly versatile processing position identification device. Note that, unlike the above-described method, the method using a projector (projection device) may simply involve attaching a point to a reference position on the truss, adjusting the scale of a projector (projection device) installed a certain distance from the reference point, and projecting a processing drawing. Then, after checking the processing drawing, punch marks may be made on the truss, and processing may be performed using a drill or the like.
