Description

The present disclosure relates to a processing position identifying device for a passenger conveyor, and, for example, to a template used to identify the processing position and a projector device that projects the processing position. The present disclosure also relates to a processing position identifying device set that is composed of a set of multiple templates used to identify the processing position. The present disclosure also relates to a processing method for a passenger conveyor.

As described in Patent Document 1, in escalator renovation work, the support members (brackets) need to be attached by screws, which requires drilling holes in the existing truss.

JP 2012-176810 A

When renovating escalators, 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.

When doing this, the work requires measuring the dimensions from the reference while looking at the blueprint in a dark place, checking the hole positions, marking with a punch, etc., and then processing with a drill, etc., which is a time-consuming process. Furthermore, there is a risk that the parts will not be installed properly due to a misreading of the dimensions or a measurement error that can lead to a deviation in the processing position, which will require redoing the processing or changing parts. These problems also exist in the construction of new escalators.

Therefore, the 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.

In order to solve the above problems, the processing position identification device for a passenger conveyor disclosed herein is a processing position identification device used when processing the passenger conveyor using one or more reference positions defined on the passenger conveyor, and includes 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 located at the placement position.

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 to apply markings to the one or more processing positions. Therefore, since processing at one or more processing positions can be performed quickly and accurately, it is easy to suppress deviations in processing positions and shorten work time in new construction and renewal construction.

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

In addition, the processing position may have a portion that extends beyond the position overlapping with the through hole when the reference portion is located at the arrangement 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 arrangement position.

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.

In addition, the processing position identification device set disclosed herein is equipped with multiple templates that are different from each other.

Generally, it is necessary to form multiple sets of holes in a truss, each with a different layout, and cutting may be performed. Furthermore, the multiple sets of holes and the cutting processes differ depending on the model of the passenger conveyor. Therefore, by preparing a template set consisting of multiple templates for each model, as in this configuration, it is possible to quickly and accurately mark all or the majority of the processing positions. Therefore, all holes and all cutting processes to be formed in the passenger conveyor can be quickly and accurately formed, or the majority of holes and the majority of the cutting processes can be quickly and accurately formed.

The processing position identification device set may also include a hole linear arrangement template having a plurality of the through holes spaced apart in a straight line.

A vertically extending member (vertically extending bracket) that extends perpendicular to the bottom surface of a truss may be attached to the truss, and the vertically extending member may have holes spaced apart in the direction of extension. In contrast, according to the present configuration, the processing position identification device set includes a linear hole placement template having a plurality of through holes that are spaced apart in a straight line. Thus, by using the linear hole placement template to provide 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.

The processing position identification device may also be provided with a projection unit that projects the one or more processing positions.

Inside the truss, it is dimly lit. Therefore, it is possible to project the processing drawing and the processing position using a projection device including a projection unit such as a projector.

According to this configuration, layout data and processing position data for multiple existing sets of holes are stored in the memory unit of the processing position identification device, and the projection device is moved while appropriately projecting the formation positions of one or more appropriately selected holes or one or more cut points at each stationary position (each projection position), thereby quickly and accurately identifying and marking the processing positions of all holes or all cut points, or the majority of holes or the majority of cut points. Thus, all holes or all cut points, or the majority of holes or the majority of cut points to be formed in the passenger conveyor, can be quickly and accurately formed.

In addition, by simply replacing the data or appropriately selecting one data set from multiple data sets that corresponds to the model to be worked on, a highly versatile processing position identification device can be realized that can easily accommodate new models or multiple models. Furthermore, since there is no need to create templates or other items, processing of passenger conveyors can be performed inexpensively.

In addition, when the reference portion is positioned at the arrangement position, the projection portion may be capable of projecting a plurality of the 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.

Processing of the side walls of a truss may include processing that is the same on both sides of the width of the truss. 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-mentioned area in the width direction of the truss, making it possible to simultaneously process the same processing on both side walls of the truss in the width direction. This makes it possible to more quickly mark the processing positions on one side wall and the other side wall.

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 the 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.

According to the present disclosure, simultaneous processing of the same processing on both sidewalls in the width direction of the truss is possible. This allows marking of the processing positions on one sidewall and the other sidewall to be performed more quickly.

The processing position identifying device for passenger conveyors, processing position identifying device set, and passenger conveyor processing method disclosed herein can suppress misalignment of the processing position and shorten working time.

The following describes in detail the embodiments of the present disclosure with reference to the accompanying drawings. In the following, when multiple embodiments or variations are included, it is assumed from the beginning that new embodiments will be constructed by appropriately combining their characteristic parts. In the following examples, the same components are given the same reference numerals in the drawings, and duplicated explanations are omitted. In addition, multiple drawings include schematic diagrams, and the dimensional ratios of length, width, height, etc. of each component do not necessarily match between different drawings. In addition, among the components described below, those not described in the independent claims that indicate the highest concept are optional components and are not essential components.

In the following description, the passenger conveyor whose processing position is identified using the processing position identification device 15, 115 of the present disclosure is 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 identification device 15, 115 of the present disclosure may be a moving walkway, or more specifically, a horizontal moving walkway or an inclined moving walkway.

Figure 1 is a perspective view showing the inside of truss 2 of escalator 1 undergoing renewal work. Escalator 1 is equipped with drive roller rails 4a, 4b, 5a, 5b that guide drive rollers located on the left and right of the width of the step from both the top and bottom in the vertical direction, and driven roller rails 6a, 6b that guide driven rollers located on the left and right of the width of the step. 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 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.

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

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 on both sides of the width direction of the truss 2. Symmetric processing is processing that is approximately plane symmetric with respect to a plane that approximately bisects at least a part of the area in the extension 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 symmetric installation brackets 7a, 8a, 9a that are attached to the first side wall portion 10a on one side of the width direction of the truss 2 and the second side wall portion 10b on the other side of the width direction of the truss 2 so as to face each other in the width direction of the truss 2. The symmetric installation brackets 7a, 8a, 9a are fixed to the side wall portions 10a, 10b on both sides of the width direction of the truss 2 by symmetric processing using a plurality of holes formed approximately plane symmetric with respect to the above-mentioned bisecting plane.

First Embodiment
Next, a description will be given of the processing position specifying device 15 of the first embodiment of the present disclosure, which is used to specify a processing position when processing the 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.

The template 20 is an example of a hole straight line arrangement template, and is used to identify the positions of a plurality of holes to be provided in the side wall portions 10a and 10b of the truss 2 in order to fix 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 in the thickness direction of the template 20 have an elongated rectangular shape. The template 20 has a plurality of through holes 21 located in a straight line at intervals in the longitudinal direction (the longitudinal direction of both 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 straight line arrangement template may have both a plurality of through holes located in a straight line and one or more other through holes. In addition, the planar shape of the through holes is not limited to a circular shape and may be any shape.

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, the first corner 22a (upper left corner in FIG. 2(a)) of the four corners 22 of the template 20 matches the corresponding first corner 19a (upper left corner in FIG. 2(b)) in the reference area 19, and the second corner 22b (lower right corner in FIG. 2(a)) of the template 20 matches the corresponding second corner 19b (lower right corner in FIG. 2(b)) in the reference area 19, and one side surface in the thickness direction of the template 20 is in contact with 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 are 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 .

Here, each reference position 11 of the escalator 1 is determined, for example, as follows: Positional information of the set of holes 14 for which multiple 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 for forming the holes 14 in the truss 2. Therefore, the positions of the sets of holes 14 in 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.

Furthermore, the relative position of the center of each of the other holes 14 to the center of one of the multiple holes 14 for which the processing position 18 of the truss 2 is specified using the template 20 coincides with the relative position of the center of each of the other through holes 21 to the center of one of the multiple 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 multiple holes 14 corresponding to the multiple through holes 21 can be accurately and quickly identified. The template 20 is an example of the main body of the processing position identification device 15, the multiple holes 14 (all the holes 14) are an example of one or more processing positions, and the multiple through holes 21 (all the through holes 21) provided in the template 20 are an example of the processing position identification portion 27.

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

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

The escalator 1 includes a number of different brackets 7, 8, and 9. Just as the template 20 was a template for mounting the bracket 9, a corresponding template for mounting each of the brackets 7, 8, and 9 can be prepared. As is clear from the above explanation, the positional relationship of the multiple through holes (centers of the through holes) provided in each of the brackets 7, 8, and 9 matches the positional relationship of the multiple through holes 21 (centers of the through holes 21) provided in the corresponding template 20, and also matches the positional relationship of the multiple holes 14 (centers of the holes 14) provided in the truss 2 to mount each of the brackets 7, 8, and 9 to the truss 2.

It is preferable to prepare a processing position identification 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 identification device set 50 may include, for example, a template 25 shown in a plan view of one side in the thickness direction in FIG. 3 in addition to the template 20. The plurality of through holes 26 formed in the template 25 may include through holes 26a arranged in a matrix. The processing position identification device set 50 may further include 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 for which the corresponding templates 20 exist may or may not be all different brackets of the escalator 1.

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 identification device set 50) provided in the processing position identification device 15 of the first embodiment is configured according to the multiple brackets 7, 8, 9 provided in the corresponding escalator 1.

As described above, the processing position identifying device 15 is used when processing the escalator 1 using one or more reference positions 11 defined on the escalator 1. The processing position identifying device 15 comprises a template (main body) 20 that can identify the position of the reference part 17 that is placed at the placement position 16 based on the reference position 11, and a processing position identifying unit 27 that can identify one or more processing positions 18 when the reference part 17 is located at the placement position 16.

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 to apply markings to the one or more processing positions 18. Therefore, since processing at the one or more processing positions 18 can be performed quickly and accurately, it is possible to suppress deviation of the processing positions 18 in new construction and renewal construction, and it is also possible to shorten the work time. Note that, although in the first embodiment, the placement position 16 coincides with the reference position 11, the placement position may be a position different from the reference position.

The processing position identifying 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 identifying portion 27. When the reference portion 17 is located at the arrangement position 16, the position that overlaps with the through hole 21 may include at least a portion of the processing position 18.

According to this configuration, by placing the template 20 at a predetermined position, one or more processing positions 18 can be quickly and accurately identified. In addition, since the template 20 is hard and not easily damaged, the processing position identifying device 15 can be easily handled during transportation, etc. Note that the processing position may have a portion that protrudes from the position overlapping the through hole when the reference portion is located at the placement position, and the entire processing position may be included in the position overlapping the through hole when the reference portion is located at the placement position.

In addition, the processing position identification device set 50 of the present disclosure is provided with multiple templates 20, 25 that are different from each other.

In general, it is necessary to form multiple sets of holes in the truss 2, each having a different layout, and cutting may be performed. The sets of holes 14 also differ depending on the model of the escalator 1. Therefore, by preparing a processing position identification device set 50 including a template set consisting of multiple templates 20, 25 for each model, as in this configuration, it is possible to quickly and accurately mark all or the majority of processing positions 18, and all holes and all cutting processes to be formed in the escalator 1, or the majority of holes and the majority of cutting processes, can be quickly and accurately formed.

The processing position identification device set 50 may also be provided with a template (hole linear arrangement template) 20 having a plurality of through holes 21 spaced apart in a straight line.

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 identification 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 provide 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.

The above description deals with the case where the reference portion 17 of the template 20 is the two corners 21a, 21b included in the template 20. However, the reference portion of the template does not have to be the two corners, and may be a portion not included in the template, or any portion of the template whose position can be identified. For example, the reference portion of the template may be configured by the center of the first through hole and the center of the second through hole formed in the template.

We have also described a case where the template 20 can be used to process multiple different locations on the escalator 1. However, the template constituting the processing position identification 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 defined on the escalator.

Also, a case has been described in which a plurality of machining 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 be used to identify only one machining position.

Also, a case has been described in which plate-shaped templates 20, 25 made of metal or resin are used to identify the processing position 18 with through holes 21, 26. However, the templates 20, 25 may have the processing position marked, and may not have through holes. The template may then be placed based on a position specified by an on-site truss or the like, a punch mark may be made using the mark on the template, and processing may then be performed using a drill or the like.

The template may also be made of a material other than metal or resin, and may be made of paper such as cardboard. 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 identified by the slits.

Second Embodiment
Fig. 4 is a block diagram showing the main configuration of the processing position specifying device 115 according to the 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 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 configured with a touch panel in which a touch sensor and a display are integrated.

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, i.e., the processor, includes, for example, a CPU (Central Processing Unit). The storage unit 126 is configured by a hard disk drive (HDD) or a solid state drive (SSD), 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 storage unit 126 may be configured by only one storage medium, or may be configured by multiple different storage media. The CPU reads out and executes programs and the like stored in the storage unit. The non-volatile memory stores a control program, a predetermined threshold value, and the like in advance. The volatile memory temporarily stores the read program and processing data.

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 method may be adopted as the projection method of 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.

The machining position identification 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.

Each of the first projection unit 121a and the second projection unit 121b has a light source and can project 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 information on the shape of each bracket and position information of the processing position on each bracket in advance.

When a person operates the processing position display operation unit 123a, the display unit 122 may display one or more truss extension direction positions (positions in the extension direction of truss 2 on the bottom surface of 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 in a linked state (hereinafter, each piece of linked information will be referred to as processing information).

The display unit 122 may display the linked multiple pieces of processing information, for example, from the top to the bottom of the screen in order starting from the data of 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 of the lowest heights may be displayed from the top to the bottom of the screen in order, and in the case of symmetric 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.

In this embodiment, the first projection unit 121a and the second projection unit 121b project the processing drawing in the opposite directions, and the first projection unit 121a and the second projection unit 121b can only be adjusted to the same height. Here, when performing different processing on the side walls 10a and 10b on both sides of the truss 2 at the same truss extension direction position of the processing position identification device 115, for example, the processing information may be projected in the order of the processing information displayed from the top on the screen of the display unit 122, and then one or more projections may be performed using the first projection unit 121a and then one or more projections may be performed using the second projection unit 121b. The memory unit 126 of the control device 124 stores data on the mounting position for each bracket for all different brackets. The display by the display unit 122 is performed based on the data on the mounting position for each bracket.

Based on the display, the person moves the processing position identification device 115 to a position in the extension direction of the truss 2 to be processed, and by operating the height adjustment operation unit 123b at that position, the linear actuator is operated appropriately to adjust the height of the projection units 121a, 121b. Furthermore, the person can select the processing drawing to be projected by the projection units 121a, 121b. This is done by selecting the bracket corresponding to the processing drawing (the bracket to be attached in that processing drawing) using the bracket selection unit 123c.

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 machining 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 machining 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).

The person can apply marking to the processing position 118 based on this projection 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. After that, the person operates the processing information deletion operation unit 123h to erase the display of the processing information displayed on the display unit 122 and for which marking has been completed. When this deletion is completed, the person again refers to the above display and moves at least one of the projection units 121a, 121b to a position corresponding to the next processing position to perform the next projection. By repeating this procedure, all processing is performed. Processing may include the above-mentioned cutting processing in addition to hole drilling processing.

Note that the display unit 122 may only be able to display a predetermined number of pieces of processing information, and may be able to cause the display unit 122 to display the next predetermined number of pieces of processing information after a person has performed marking of a predetermined number (the predetermined number being any natural number) corresponding to the predetermined number of pieces of processing information. The display unit 122 may also perform a display that allows a person to recognize that this is the last piece of processing information. This display may be performed, for example, by displaying the last piece of processing information in color (for example, green), or by displaying a notation indicating that this is the last piece of processing information after the last piece of processing information. This notation may be performed, for example, by displaying (last), or by displaying the last character in parentheses, etc.

Figure 6 is a schematic plan view of the processing position identification 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 inside the truss 2. Note that in Figure 6, the inside of the side walls 10a and 10b, which are not actually visible, is shown in cross section. As shown in Figure 6, the processing position identification device 115 is disposed 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 unit 121a to the first side wall 10a is approximately the same as the width direction distance of the truss 2 from the second projection unit 121b to the second side wall 10b. In the state shown in Figure 6, the first projection unit 121a and the second projection unit 121b are at the same vertical position. 6, the first projection unit 121a and the second projection unit 121b are disposed substantially symmetrically with respect to a plane that passes through the center of the width direction of the truss 2 and extends vertically through a portion of the region 2a in the extension direction of the truss 2, i.e., a plane P that bisects the region 2a in the width direction. This allows the projection unit 121 to project a plurality of processing positions that are substantially symmetrical with respect to the plane P that bisects the region 2a in the width direction of the truss 2.

As described above, the 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 area 2a in the width direction of the truss 2, so that simultaneous processing can be performed on both sides in the width direction for the same symmetric processing on the side walls 10a, 10b on both sides in the width direction of the truss 2. Therefore, the marking of the processing positions on the first side wall 10a and the second side wall 10b can be performed even more quickly.

Figure 7 is a flow chart explaining an example of a procedure for marking multiple processing positions using the processing position identification device 115. Referring to Figure 7, first, in step S1, the processing position display operation unit 123a is operated. Then, in step S2, the display unit 122 displays multiple pieces of processing information. Here, each piece of processing information is information that links the truss extension direction position, the projection units 121a, 121b operated at each truss extension direction position, the height of the projection units 121a, 121b operated at each truss extension direction position, and bracket information corresponding to the processing drawing projected by the projection units 121a, 121b.

The display unit 122 displays the linked multiple pieces of processing information, for example, from the top to the bottom of the screen in order starting from the data on the truss extension direction position closest to one end of the escalator 1 in the passenger transport direction, and when multiple processing operations with different heights are performed at the same truss extension direction position, the processing positions with the lowest heights are displayed from the top to the bottom of the screen in order. Also, when symmetric 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.

In the next step S3, a person moves the projection units 121a and 121b to positions where the person can project the processing position corresponding to the processing information written at the top of the display unit 122 based on the processing information. 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.

In this embodiment, since the relative position of the second projection unit 121b with respect to the first projection unit 121a cannot be changed, when 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 (for example, the center of two holes) or the center of three processing positions (for example, the center of three holes) included in the wall surface of one side wall unit 10a. In addition, the arrangement position 116 (see FIG. 6) is, for example, a position where the two corners 139a, 139b of the base unit 139 overlap with 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. In addition, the reference unit 117 (see FIG. 6) is composed of the two corners 139a, 139b of the base unit 139 and the center of the lens surface of the first projection unit 121a. Further, the main body of the processing position specifying device 115 capable of specifying the reference portion 117 is constituted by the processing position specifying device itself.

In the next step S4, the bracket selection unit 123c is operated to select a processing drawing, and then in step S5, projection is performed by the corresponding projection units 121a and 121b based on the projection unit information linked to the processing information. Here, when the above-mentioned symmetric processing is performed on the side wall portions 10a and 10b on both sides, the two projection units 121a and 121b simultaneously project the processing drawing onto the side wall portions 10a and 10b on both sides. In the next step S6, a person marks the processing position based on the processing image projected by the projection units 121a and 121b, and then in step S7, the projection of the projection units 121a and 121b is terminated.

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 judgment is made in step S8, an operation is performed in step S9 to erase from the display the processing information for which marking of the corresponding processing positions has been completed among the processing information displayed on the display unit 122 by operating the operation unit 123. Here, if symmetric 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 written at the top and the processing information written second highest, are erased. When step S9 is completed, steps S3 and onward are repeated. On the other hand, if a positive judgment is made in step S8, marking of the processing positions is completed.

As described above, the processing position identification device 115 of one embodiment may be equipped with 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 position can be projected.

According to this configuration, layout data and processing position data for multiple sets of holes are stored in the memory unit 126 of the processing position identification 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 cut points at each stationary position (each projection position), thereby quickly and accurately identifying and marking the processing positions of all holes or all cut points, or the majority of holes or the majority of cut points. Thus, all holes or all cut points, or the majority of holes or the majority of cut points to be formed in the escalator 1, can be quickly and accurately formed.

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 identification device 115. Furthermore, since there is no need to create templates or other items, processing of passenger conveyors can be performed inexpensively.

In addition, 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-symmetrical with respect to a plane P that approximately bisects at least a portion of the region 2a in the extension direction of the truss 2 in the width direction of the truss 2.

As described above, the processing of the side walls of the truss 2 may include 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 area 2a in the width direction of the truss 2, so that simultaneous processing can be performed 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, the marking of the processing positions on the first side wall 10a and the second side wall 10b can be performed even more quickly.

The processing method for a passenger conveyor according to the present disclosure is a processing method for a passenger conveyor using a processing position identification 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.

According to the present disclosure, it is possible to simultaneously process both sides in the width direction of the truss 2 for the same symmetrical processing on the side walls 10a and 10b. Therefore, it is possible to more quickly mark the processing positions of the first side wall 10a and the second side wall 10b.

Note that this disclosure is not limited to the above-described embodiments and their variations, and various improvements and modifications are possible within the scope of the matters described in the claims of this application and their equivalents.

For example, since the template constituting the processing position identification device of the first embodiment is often used in dimly lit places, it is preferable that the outer surface is coated with fluorescent paint. The template may also have one or more magnets attached (fixed) to the surface that is to be abutted against the wall surface. If the wall surface is made of metal, the template may be fixed to the wall surface by the magnetic force of a magnet. In this way, deviation of the template can be suppressed, and furthermore, marking of the processing position can be performed with high accuracy. Furthermore, when a magnet is fixed to the template, marking can be performed by one person, making the marking more efficient.

In the processing position identification device of the second embodiment, the projection unit may be supported by a tripod. In the second embodiment, the processing position identification device 115 has two projection units 121a and 121b. However, the processing position identification device may have only one projection unit, and the direction of the projection unit when projecting the processing diagram onto the first side wall portion 10a on one side of the width direction of the truss 2 may be opposite to the direction of the projection unit when projecting the processing diagram onto the second side wall portion 10b on the other side of the width direction of the truss 2, thereby marking the side wall portions 10a and 10b on both sides of the width direction of the truss 2.

In addition, the processing position identification device 115 of the second embodiment may be configured as an integrated, inseparable device. Alternatively, the processing position identification device 115 of the second embodiment may include a mechanism in which a projator and an information terminal (such as a personal computer, tablet, mobile phone (smartphone), etc.) on which a dedicated application for executing the above-mentioned operation is installed are connected by a cable.

As described above, by using a template as in the first embodiment, the processing position can be grasped instantly, so that the work time can be significantly shortened and errors in reading dimensions and measurement can be reduced. In addition, by using a projector (projection device) instead of a template as in the second embodiment, not only can the material cost of templates, which are generally required in multiple copies, be reduced, but also the data can be managed to reuse it for other objects, and a processing position identification device with excellent versatility can be constructed. In addition, in the method using a projector (projection device), unlike the above-mentioned method, a point can be simply attached to the position that is the reference of the truss, and the scale of the projector (projection device) installed at a certain distance from the reference can be adjusted to project the processing drawing, using the point as the reference. Then, the processing drawing can be confirmed, a punch mark can be made on the truss, and processing can be performed with a drill or the like.
