Description

[Technical Field]

[0001] The present invention relates to a maintenance method for a processing apparatus. [Background technology]

[0002] Processing equipment for processing objects, such as cutting equipment, cleaning equipment, and inspection equipment, requires maintenance work by operators to ensure accurate and continuous processing. Maintenance work for processing equipment is complex and diverse. Therefore, to ensure that operators can perform maintenance work accurately, multiple manuals are used that describe maintenance procedures corresponding to the maintenance content of the processing equipment.

[0003] When performing maintenance work on a processing device, an operator refers to a manual corresponding to the maintenance work and performs the maintenance work on the processing device according to the maintenance procedure in the manual.

[0004] As a management method for a processing device, a management method has been disclosed in which a processing means and / or a monitoring camera of the processing device is remotely controlled from a terminal device via a communication line (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-021666 Summary of the Invention [Problem to be solved by the invention]

[0006] However, there are many manuals for performing maintenance work on processing equipment, and therefore, when an operator performs maintenance work according to a manual, there is a risk that the operator may perform the maintenance work by referring to a manual different from the manual that the operator should actually refer to.

[0007] Furthermore, there are many maintenance tasks for processing equipment, and therefore, when an operator performs maintenance tasks according to the manual, there is a risk that the operator may perform the maintenance tasks according to a procedure that differs from the procedure that the operator should actually perform.

[0008] For this reason, there has been a demand for a system that allows an operator to confirm, when performing maintenance work on a processing device while referring to a manual, whether the correct manual corresponding to the maintenance work to be performed is being referred to and whether the maintenance work performed is being performed according to the correct maintenance procedures.

[0009] The present invention has been made in consideration of the above points, and aims to provide a maintenance method for a processing device that can confirm that the manual referred to during maintenance work is correct and that the maintenance procedure performed is correct. [Means for solving the problem]

[0010] One aspect of the present invention is a maintenance method for a processing device that processes objects to be processed, characterized by comprising a reading step of reading an identification code from a manual containing a maintenance procedure and an identification code for the processing device using a reading unit and recording the type of the manual, and a work step of capturing an image of maintenance work performed in accordance with the manual using an imaging unit and recording the captured image.

[0011] The reading unit may be the imaging unit.

[0012] The method may further include a confirmation step of confirming from the image recorded in the work step whether the type of the manual recorded in the reading step matches the maintenance work performed in the work step.

[0013] The method may further include a notification step of determining whether the maintenance procedure corresponding to the identification code read in the reading step matches the log of the maintenance work performed in the work step based on linking data linking the identification code with the maintenance work of the processing device performed in the work step, and notifying an error if they do not match. [Effects of the Invention]

[0014] According to the maintenance method for a processing apparatus of the present invention, it is possible to confirm that the manual referred to during maintenance work is correct and that the maintenance procedure performed is correct. [Brief explanation of the drawings]

[0015] [Figure 1] FIG. 1 is a diagram illustrating an example of a processing apparatus in which maintenance work is performed by an operator who refers to a manual. [Figure 2] 10 is an example of a video of a maintenance work captured by an imaging unit. [Figure 3] This is an example of a maintenance procedure shown in a manual. [Figure 4] FIG. 10 is a diagram illustrating an example of linked data recorded in a storage unit. DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, a maintenance method for a processing device according to this embodiment will be described with reference to the accompanying drawings. Fig. 1 is a diagram showing an example of a processing device in which maintenance work is performed by an operator 70 who refers to a manual 80. In Fig. 1, a cutting device 10 is shown as an example of the processing device.

[0017] The processing device is not limited to the cutting device 10, but may be a processing device for a workpiece, an inspection device, a cleaning device, a tape application device, a tape peeling device, an imaging device, or the like.

[0018] The manual 80 includes an identification code 81 and a maintenance procedure 82 for the cutting device 10. The identification code 81 and the maintenance procedure 82 are shown in the manual 80. For example, the identification code 81 and the maintenance procedure 82 are described in the manual 80.

[0019] The identification code 81 is identification information that can identify any one of the multiple manuals as a manual 80. A QR code (registered trademark) can be used as the identification code 81. In the embodiment shown in FIG. 1, a QR code is used as the identification code 81, but this is not limited thereto, and any identification information that can be read by a reading unit and can uniquely identify each manual may be used.

[0020] For example, the identification code 81 may be any barcode, two-dimensional code, character string, symbol, shape such as a notch or an uneven surface, color, or hole. The identification information included in the identification code 81 includes any identification symbol. The identification symbol may include uppercase or lowercase alphabets, Greek letters, numbers, symbols, or a combination thereof. In this embodiment, the combination of alphabets and numbers "A001" is used as the identification information included in the identification code 81, but this is not limited to this.

[0021] The maintenance procedure 82 is information indicating the order and details thereof that can be used as a reference when maintaining, managing, or servicing each component part that makes up the cutting device 10. The maintenance procedure 82 indicates any maintenance details, such as, for example, replacing the holding table, cleaning the holding table, scrubbing the holding surface of the holding table, shaping the cutting blade, and replacing cutting blades and other processing tools.

[0022] Although FIG. 1 shows only one manual 80, this is not a limitation and different manuals may be prepared for different processing devices. Also, different manuals 80 may be prepared for different types of processing devices. For example, a manual may be prepared for any type of device, such as a processing device, an inspection device, a cleaning device, a tape application device, a tape peeling device, or an imaging device. Also, different manuals 80 may be prepared for different types of processing objects processed by each processing device, even if they are the same type of maintenance work for the same type of processing device. For example, different manuals may be prepared for a device that manufactures workpieces for automotive use and a device that processes workpieces for precision parts, even if they are the same type of processing device and the same type of maintenance items.

[0023] Furthermore, the manual 80 may have multiple identification codes and multiple maintenance procedures written on multiple pages, and may contain instructions for multiple maintenance tasks in one manual. Alternatively, a different manual 80 may be prepared for each maintenance procedure 82 of the processing equipment. For example, separate manuals may be prepared for replacing the holding table, cleaning the holding table, scrubbing the holding surface of the holding table, shaping the cutting blade, replacing cutting blades and other processing tools, etc.

[0024] The X-axis, Y-axis, and Z-axis directions shown in each diagram are perpendicular to one another. The X-axis and Y-axis directions are nearly horizontal, and the Z-axis direction is up-down (vertical). In each diagram, of the two arrows indicating the X-axis direction, the +X side is the left and the -X side is the right. Of the two arrows indicating the Y-axis direction, the -Y side is the front and the +Y side is the rear. Of the two arrows indicating the Z-axis direction, the +Z side is the up and the -Z side is the down.

[0025] A cutting device 10 shown as an example of a processing device includes a cutting unit 11 that cuts a workpiece 90, a cutting unit 12, and an imaging unit 60. The cutting unit 11 and the cutting unit 12 each include a cutting blade (not shown), and cut the workpiece 90 using the cutting blade. The workpiece 90 is an example of an object to be processed.

[0026] The imaging unit 60 is an example of a reading unit. By using a reading unit as the imaging unit 60, there is no need to provide a dedicated reading unit, and the cost of the device can be reduced. In the embodiment shown in FIG. 1, the imaging unit 60 is shown as an example of a reading unit, but this is not limiting and any device unit that can read the identification code 81 written in the manual 80 may be used. For example, a dedicated barcode reader or a QR code reader may be used as the reading unit.

[0027] The cutting device 10 of this embodiment is equipped with two cutting units 11 and 12 and is capable of simultaneously processing two locations on the workpiece 90, but the number of cutting units is not limited to two and may be one or three or more cutting units. In other words, it is sufficient to have at least one cutting unit.

[0028] The cutting device 10 is controlled by a control unit 100. The control unit 100 has a processing unit 101 (processor) that generates signals for controlling each part of the cutting device 10, and a storage unit 102 that stores various information used by the processing unit 101. The processing unit 101 controls the operation of each part of the cutting device 10, which will be described later, by reading and executing a program stored in the storage unit 102. The storage unit 102 records linking data 600, which will be described later. The control unit 100 may also include a communication unit that enables communication with external devices (such as a server, a personal computer, a smartphone, or a tablet terminal).

[0029] The cutting device 10 has a base 13, and various components are arranged on the base 13. A cassette 15 is placed on a cassette placement section 14 provided in a corner of the base 13. Workpieces 90 are carried into the cutting device 10 while housed in the cassette 15. The cassette 15 can house multiple workpieces 90, and the height position of the workpieces 90 being taken in and out of the cassette 15 is adjusted by raising and lowering the cassette placement section 14.

[0030] An opening 16 is formed on the base 13 at a position adjacent to the cassette placement portion 14 in the Y-axis direction. The opening 16 extends in the X-axis direction, and a table cover 17 is supported inside the opening 16, with a holding table 18 provided on the table cover 17. The holding table 18 is a table having a holding surface 19 on its upper surface that holds the workpiece 90. The holding table 18 is provided with clamps 20 on the outside of the holding surface 19. The holding table 18 also has a suction mechanism (not shown) that applies a suction force to the holding surface 19 to suck and hold the workpiece 90. Bellows 21 are connected to both sides of the table cover 17 in the X-axis direction, and the opening 16 is covered by the table cover 17 and the bellows 21.

[0031] The table cover 17 and the holding table 18 are moved in the X-axis direction by a table feed mechanism (not shown) provided inside the base 13 below the opening 16. The table feed mechanism includes an X-axis guide rail and an X-axis ball screw extending in the X-axis direction, and a base portion supporting the table cover 17 and the holding table 18 is supported by the X-axis guide rail so as to be movable in the X-axis direction. The X-axis ball screw is threadedly engaged with the base portion, and when the X-axis ball screw is rotated by a motor, the base portion moves in the X-axis direction. In addition, the holding table 18 is rotated by a table rotation mechanism (not shown) around an axis facing the Z-axis direction relative to the base portion.

[0032] The table cover 17 and the holding table 18 can be moved in the X-axis direction by a table feed mechanism and positioned in a carry-in / out area adjacent to the cassette mounting section 14 and in a processing area below the cutting units 11 and 12. Above the carry-in / out area of the holding table 18, a pair of holding rails 22 are provided that extend in the Y-axis direction and cross above the opening 16. The distance between the pair of holding rails 22 in the X-axis direction can be changed.

[0033] A cleaning unit 23 is provided on the base 13, on the opposite side of the Y-axis direction from the cassette mounting unit 14, with the opening 16 in between. The cleaning unit 23 includes a spinner table 24 that can hold and rotate the workpiece 90, and a cleaning nozzle (not shown) that sprays cleaning liquid and drying air toward the workpiece 90 on the spinner table 24.

[0034] A gate-shaped column 26 is provided on the base 13 and straddles the opening 16 in the Y-axis direction. The column 26 is provided with guide rails 27 and 28 extending in the Y-axis direction. A slider 29 that is movable in the Y-axis direction along the guide rail 27, and a slider 30 that is movable in the Y-axis direction along the guide rail 28 are provided. The slider 29 supports a transfer arm 31 so that it can move in the Z-axis direction. The slider 30 supports a transfer arm 32 so that it can move in the Z-axis direction. In other words, the transfer arms 31 and 32 are supported so that they can move in the Y-axis direction and the Z-axis direction, respectively.

[0035] The transport arm 31 transports the workpiece 90 between the cassette 15 placed on the cassette placement section 14 and the holding table 18 located in the carry-in / out area. The transport arm 31 includes a suction holding section that suction-holds the upper surface of the workpiece 90 and a gripping section that grips the edge of the workpiece 90. The transport arm 31 pulls the workpiece 90, held by the gripping section, out of the cassette 15 and places it on a pair of holding rails 22. After positioning the workpiece 90 in the X-axis direction using the pair of holding rails 22, the suction holding section of the transport arm 31 holds the upper surface of the workpiece 90, and the transport arm 31 is lowered to place the workpiece 90 on the holding surface 19 of the holding table 18 located in the carry-in / out area. The holding table 18 with the workpiece 90 placed on it holds the workpiece 90 on the holding surface 19 by the suction force of a suction mechanism, and is moved from the carry-in / out area to the processing area by a table feed mechanism.

[0036] When the workpiece 90 is supported by a ring-shaped frame, the workpiece 90 is held by suction on the holding surface 19 and the frame is fixed by the clamp 20 of the holding table 18 .

[0037] In the machining area, cutting of the workpiece 90 is performed using the cutting unit 11 and the cutting unit 12.

[0038] The transport arm 32 transports the workpiece 90 between the holding table 18, which is located in the carry-in / out area, and the cleaning unit 23. When cutting of the workpiece 90 is completed, the table feed mechanism moves the holding table 18 from the processing area in the X-axis direction to the carry-in / out area. The transport arm 32 holds the workpiece 90 on the holding surface 19 of the holding table 18 that has moved to the carry-in / out area, transports it to the cleaning unit 23, and places it on the spinner table 24. Then, a cleaning liquid is sprayed from a cleaning nozzle and the spinner table 24 is rotated to clean the workpiece 90. Air is also sprayed from the cleaning nozzle to dry the workpiece 90 after cleaning.

[0039] When cleaning of the workpiece 90 in the cleaning section 23 is completed, the workpiece 90 on the spinner table 24 is held by the transport arm 32, and the transport arm 32 is moved in the Y-axis direction to place the workpiece 90 on the pair of holding rails 22. The workpiece 90 is positioned in the X-axis direction by the pair of holding rails 22, and then the workpiece 90 is gripped by the gripping section of the transport arm 31. The transport arm 31 is then moved in the Y-axis direction to transport the workpiece 90 to the cassette mounting section 14 and store it inside the cassette 15. In this way, the workpiece 90 that has been cut and cleaned is recovered into the cassette 15.

[0040] In the back area of the column 26, behind the guide rails 27 and 28, there are provided an indexing feed unit 33 and an indexing feed unit 34 which move the cutting unit 11 and the cutting unit 12 in the Y-axis direction, respectively, and a lifting unit 35 and a lifting unit 36 which raise and lower the cutting unit 11 and the cutting unit 12 in the Z-axis direction, respectively.

[0041] A pair of Y-axis guide rails (not shown) extending in the Y-axis direction and a pair of Y-axis ball screws (not shown) are provided on support plate 37 fixed to column 26. The pair of Y-axis guide rails support Y-axis moving table 38 and Y-axis moving table 39 so that they can move in the Y-axis direction. One Y-axis ball screw is threaded into a female screw portion (not shown) provided on Y-axis moving table 38, and the other Y-axis ball screw is threaded into a female screw portion (not shown) provided on Y-axis moving table 39. By driving one Y-axis ball screw to rotate with a motor (not shown), Y-axis moving table 38 moves in the Y-axis direction. By driving the other Y-axis ball screw to rotate with a motor (not shown), Y-axis moving table 39 moves in the Y-axis direction.

[0042] The Y-axis moving table 38 and the mechanism for moving it (Y-axis guide rail, Y-axis ball screw, and motor) constitute the indexing feed unit 33. The Y-axis moving table 39 and the mechanism for moving it (Y-axis guide rail, Y-axis ball screw, and motor) constitute the indexing feed unit 34.

[0043] The Y-axis moving table 38 is provided with a pair of Z-axis guide rails (not shown) extending in the Z-axis direction and a Z-axis ball screw (not shown). The pair of Z-axis guide rails support the Z-axis moving table 40 so that it can move in the Z-axis direction, and the Z-axis ball screw is threaded into a female thread portion (not shown) provided on the Z-axis moving table 40. The Z-axis ball screw is rotated and driven by a motor 351, thereby moving the Z-axis moving table 40 in the Z-axis direction. The Z-axis moving table 40 and the mechanism for moving it (the Z-axis guide rails, the Z-axis ball screw, and the motor 351) form the lifting unit 35.

[0044] The Y-axis moving table 39 is provided with a pair of Z-axis guide rails (not shown) extending in the Z-axis direction and a Z-axis ball screw (not shown). The pair of Z-axis guide rails support a Z-axis moving table 41 so that it can move in the Z-axis direction, and the Z-axis ball screw is threaded into a female thread portion (not shown) provided in the Z-axis moving table 40. The Z-axis ball screw is rotated and driven by a motor 361, thereby moving the Z-axis moving table 41 in the Z-axis direction. The Z-axis moving table 41 and the mechanism for moving it (the Z-axis guide rails, the Z-axis ball screw, and the motor 361) form the lifting unit 36.

[0045] The cutting unit 11 is supported at the lower end of the Z-axis moving table 40, and the cutting unit 12 is supported at the lower end of the Z-axis moving table 41. Therefore, the cutting unit 11 is moved in the Y-axis direction by the indexing feed unit 33, and is raised and lowered in the Z-axis direction by the lifting unit 35. The cutting unit 12 is moved in the Y-axis direction by the indexing feed unit 34, and is raised and lowered in the Z-axis direction by the lifting unit 36.

[0046] When cutting the workpiece 90, the control unit 100 adjusts the relative positions of the holding table 18 and each cutting unit 11, 12 in the X-axis direction and the Y-axis direction using the table feed mechanism and each indexing feed unit 33, 34, and positions the cutting blade of each cutting unit 11, 12 above the end of the processing line to be cut. Next, the control unit 100 lowers each cutting unit 11, 12 using each lifting unit 35, 36. The cutting blade of each cutting unit 11, 12 cuts into the workpiece 90 held on the holding table 18 while rotating. Then, the table feed mechanism moves the holding table 18 in the X-axis direction (processing feed), whereby cutting with the cutting blade is performed along the processing line extending in the X-axis direction.

[0047] When cutting processing along a set of processing lines by each of the cutting units 11, 12 is completed, the control unit 100 causes each of the cutting units 11, 12 to rise using each of the lifting units 35, 36, and moves the cutting blade away from the workpiece 90. Next, the control unit 100 causes each of the cutting units 11, 12 to move in the Y-axis direction (indexing feed) using each of the indexing feed units 33, 34, and positions the cutting blade of each of the cutting units 11, 12 above the end of the next uncut processing line. Then, in the same manner as above, each of the lifting units 35, 36 causes each of the cutting units 11, 12 to descend (cutting feed), and the table feed mechanism causes the holding table 18 to move in the X-axis direction (processing feed), and cutting processing is performed along the processing line.

[0048] When cutting along all of the processing lines aligned in the Y-axis direction is completed, the control unit 100 rotates the holding table 18 by 90 degrees using the table rotation mechanism. As a result, the workpiece 90 on the holding table 18 is in a state where multiple uncut processing lines are aligned in the Y-axis direction (extending toward the X-axis direction). Then, in the same manner as above, each cutting unit 11, 12 is caused to perform cutting processing sequentially along all of the uncut processing lines.

[0049] It is also possible to operate only one of the two cutting units 11 and 12 to perform cutting processing for each processing line.

[0050] The cutting device 10 is provided with a display monitor 56, an indicator lamp 57, and a speaker 58 in a housing 55 (only a portion of the housing 55 is shown in FIG. 1) that covers the top of the base 13. The display monitor 56 functions as an information display unit that displays various information related to the operation and settings of the cutting device 10. The indicator lamp 57 is a lamp that can display multiple colors and can change the lighting pattern of each color (continuous lighting, flashing, etc.). The speaker 58 functions as a sound generation unit that generates voice and alarm sounds. The display monitor 56, the indicator lamp 57, and the speaker 58 function as a notification unit that notifies an operator 70 performing maintenance work on the cutting device 10 of errors.

[0051] In addition, the cutting device 10 is equipped with a communication unit that enables communication with external devices (such as servers, personal computers, smartphones, and tablet terminals), and it is also possible to send information from the communication unit of the cutting device 10 to the external device, thereby using the external device as an alarm unit.

[0052] The cutting device 10 includes an imaging unit 60 for capturing an image of the cutting device 10. The imaging unit 60 is disposed at a position adjacent to the cutting unit 11.

[0053] The imaging unit 60 is electrically connected to the control unit 100. The imaging unit 60 captures an image of the cutting device 10 and acquires an image of the workpiece 90 that is the object to be processed by the cutting device 10. In this embodiment, the imaging unit 60 captures an image of the workpiece 90 that is the object to be processed by the cutting device 10 and acquires a video of the workpiece 90 that is the object to be processed by the cutting device 10. In this embodiment, the image captured by the imaging unit 60 is a video, but this is not limited to this. The image captured by the imaging unit 60 may also be a still image. In other words, the image in this embodiment is a concept that includes both a video and a still image.

[0054] The images captured by the imaging unit 60 are captured and recorded in a work step described below. The images captured by the imaging unit 60 are data that are referenced when the operator 70 checks, based on the recorded images, whether the type of maintenance work described in the manual 80 matches the maintenance work performed by the operator 70 in a confirmation step described below. In other words, the images captured by the imaging unit 60 are referenced when the operator 70 checks, based on the recorded images, whether the maintenance work described in the manual 80 was actually performed by the operator 70.

[0055] The imaging unit 60 sends image data captured by the imaging unit 60 to the control unit 100. Although a single imaging unit 60 is shown in FIG. 1, this is not limiting and multiple imaging units may be provided.

[0056] The imaging unit 60 constantly captures images while power is being supplied to the cutting device 10, and sends the captured image data to the control unit 100. The imaging unit 60 constantly captures images, but this is not limited to this, and the imaging unit 60 may capture images only when an instruction is received based on the operation of the operator 70 or when maintenance work is being performed.

[0057] In FIG. 1 , the imaging unit 60 is disposed in front of the cutting unit 11 so as to capture an overhead image of the workpiece 90, which is the target of processing by the cutting device 10. The placement of the imaging unit 60 is not limited to being adjacent to and in front of the cutting unit 11, but may be located in any position that can capture images of the cutting device 10. The imaging unit 60 is provided on the cutting device 10 and is disposed to check for foreign objects on the holding table 18 above the conveyor, but is not limited to this. The imaging unit 60 may be an imaging unit that captures images of the interior of the processing device, or may be an imaging unit that captures images of the outside of the processing device when processing device maintenance work is performed using an imaging unit located outside the processing device, such as checking for water leaks in panels or the bottom of the device. Furthermore, although the imaging unit 60 is provided on the cutting device 10, the imaging unit 60 is not limited to this and may be a surveillance camera provided in a room where the cutting device 10 is provided. The imaging unit 60 captures an image of the workpiece 90 that is the object of processing by the processing device, but this is not limited to this, and the imaging unit may also capture an image of the exterior of the cutting device 10, any location within the cutting device 10, the workpiece 90 transported to the transport area, the interior of the cutting device 10, or the transported object that is the object of transport by the processing device.

[0058] The control unit 100 captures images of the maintenance work performed by the operator 70 in accordance with the manual 80 using the imaging unit 60. The imaging unit 60 sends the captured video data to the control unit 100. The control unit 100 records the video data captured by the imaging unit 60 in the storage unit 102. The control unit 100 may also record information on the date and time when the video was captured by the imaging unit 60, information on the date and time when the video data captured by the imaging unit 60 was recorded, or information such as the name or ID of the operator 70 who performed the maintenance work, in the storage unit 102. Note that the storage unit 102 may be provided in the processing device, or the captured video data may be transmitted to a server via a wired or wireless connection and recorded by the server.

[0059] The control unit 100 may transmit the imaging data of the moving image captured by the imaging unit 60 to an external device such as a server, and record the imaging data of the moving image in a storage unit of the external device. The timing at which the control unit 100 transmits the imaging data of the moving image transmitted from the imaging unit 60 to the external device may be any timing, such as when the data size of the imaging data of the moving image reaches a predetermined threshold or more, when the free space in the storage unit 102 reaches a predetermined threshold or more, at any time, when the cutting device 10 is powered on, when the cutting device 10 is powered off, or a combination thereof.

[0060] 2 is an example of a video 200 of maintenance work captured by the imaging unit 60. The video 200 of maintenance work is an image captured when an operator 70 performs maintenance work in a work step according to the manual 80. The video 200 of maintenance work is referenced when the operator 70 performs a confirmation step in which the operator 70 confirms, based on the recorded image, whether the type of maintenance work in the manual 80 matches the maintenance work performed by the operator 70.

[0061] Maintenance work video 200 includes two videos 201 and 202. Video 201 and video 202 do not need to be separated into two, and may be combined into one. Video 201 is an example of an image for confirming the second work performed in the maintenance work. Video 202 is an example of an image for confirming the third work performed in the maintenance work. Although not shown, video 200 may also include an image for confirming the first work performed in the maintenance work.

[0062] The video 201 shows the operator 70 injecting fluid 301 from the holding table 18 in accordance with the maintenance procedure shown in the manual 80. The fluid 301 is made of water. The fluid 301 may be made of water, air, two fluids (e.g., two different types of fluids), or any combination thereof.

[0063] The video 202 shows the operator 70 scrubbing the holding table 18 with a cleaning member 302 in accordance with the maintenance procedure shown in the manual 80. The cleaning member 302 is made of Arkansas stone. The cleaning member 302 may also be made of Arkansas stone, an oil stone, a grindstone, a brush, a sponge, or any combination thereof.

[0064] FIG. 3 is an example of a maintenance procedure 82 shown in the manual 80. The operator 70 refers to the maintenance procedure 82 when performing maintenance work. The maintenance procedure 82 shown in FIG. 3 shows three detailed procedures 821 to 823. Although FIG. 3 shows three detailed procedures, this is not a limitation and it is sufficient that at least one detailed procedure is shown. The detailed procedure 821 shows a procedure for transporting the holding table 18. The detailed procedure 822 shows a procedure for ejecting the fluid 301 from the holding table 18. The detailed procedure 823 shows a procedure for scrubbing the holding table 18 with the cleaning member 302.

[0065] When performing the work steps of the maintenance method for the cutting device 10, the operator 70 can smoothly perform the maintenance work by referring to detailed procedures 821 to 823 included in the maintenance procedure 82 shown in the manual 80.

[0066] In the confirmation step, the operator 70 can confirm whether the type of manual 80 corresponding to the identification code 81 captured by the imaging unit 60 matches the maintenance work performed by the operator 70, based on the video 200 of the maintenance work recorded in the storage unit 102. That is, when the confirmation step is performed, the video 200 of the maintenance work is displayed, for example, on the display monitor 56. Then, by visually checking the video 200 displayed on the display monitor 56, the operator 70 can confirm whether the type of manual 80 corresponding to the identification code 81 captured by the imaging unit 60 matches the maintenance work performed by the operator 70 in accordance with the maintenance procedure 82 in the manual 80.

[0067] The control unit 100 records the details of operations performed in the maintenance work carried out in the work step as a log in the storage unit 102. Examples of the maintenance work log that is recorded include information about the button selected when input from a movement button or blow button is received on the display monitor 56 configured as a touch panel, information about the axial movement of each component part that makes up the cutting device 10, or information about turning on the water or air jet. The control unit 100 may record in the storage unit 102 information about the date and time when the operations performed in the maintenance work were performed, or information about the date and time when the details of the operations performed in the maintenance work were recorded as a log, or information such as the name or ID that can arbitrarily identify the operator 70 who performed the maintenance work, as part of the log.

[0068] The control unit 100 may transmit a log of operations performed during the maintenance work to an external device, and the log of operations performed during the maintenance work may be recorded in a storage unit of the external device. The timing at which the control unit 100 transmits the log of operations performed during the maintenance work to the external device may be any timing, such as when the data size of the log of operations performed during the maintenance work reaches a predetermined threshold or more, when the free space in the storage unit 102 reaches a predetermined threshold or more, at any time, when the cutting device 10 is powered on, when the cutting device 10 is powered off, or a combination thereof.

[0069] Next, each step of the maintenance method for performing maintenance on the cutting device 10 will be described. The control unit 100 is the main control unit for each of the following steps. Note that the following description of each step corresponds to the case where the cutting device 10 is in a maintenance state under the control of the control unit 100. A maintenance method for performing maintenance on the cutting device 10 can be considered as a maintenance method for a processing device of the present invention as long as it includes at least a reading step and an operation step. The maintenance method for performing maintenance on the cutting device 10 may include a confirmation step in addition to the reading step and the operation step.

[0070] Each of the following steps is executed when an instruction signal instructing maintenance of cutting device 10 is input to control unit 100. For example, display monitor 56 may be configured as an input-enabled touch panel, and an instruction signal may be input when an operator touches an operation icon displayed on display monitor 56. Alternatively, an instruction signal may be sent to control unit 100 from an external device (such as a server, personal computer, smartphone, or tablet terminal) provided separately from cutting device 10 to start processing.

[0071] [Read Step] When control unit 100 receives the above instruction signal, operator 70 prepares manual 80 for performing maintenance work on cutting device 10 and holds identification code 81 shown in prepared manual 80 within the imaging range of imaging unit 60. Imaging unit 60 reads identification code 81 that comes within the imaging range of imaging unit 60. In other words, before performing maintenance work, operator 70 can have identification code 81 shown in manual 80 for cutting device 10 read by holding the identification code shown in manual 80 for the maintenance work to be performed over imaging unit 60.

[0072] Because the type of manual 80 corresponds to the identification code 81, the control unit 100 records in the storage unit 102 information on the type of manual 80 that corresponds to the identification code 81 read by the imaging unit 60. For example, the control unit 100 records in the storage unit 102 "cleaning of holding table" that corresponds to "A001" as information on the type of manual 80 that corresponds to the identification code 81. The control unit 100 may transmit information on the type of manual 80 that corresponds to the read identification code 81 to an external device via a communication unit, and record the transmitted information on the type of manual 80 in the storage unit of the external device.

[0073] In the reading step, the imaging unit 60 is used to capture an image of the identification code 81 shown on the manual 80, and the type of manual 80 used is recorded. This makes it easy to later check which manual 80 was referred to during maintenance work when a problem such as a product defect or equipment trouble occurs.

[0074] [Work Step] The imaging unit 60 captures images of the maintenance work performed by the operator 70 in accordance with the manual 80 read in the reading step. The imaging unit 60 transmits the captured video imaging data to the control unit 100. Upon receiving the video imaging data from the imaging unit 60, the control unit 100 records the received video imaging data in the storage unit 102.

[0075] The moving image data recorded in the storage unit 102 in the work step can be displayed on the display monitor 56 as needed.

[0076] During the work steps, the imaging unit 60 captures and records video of the maintenance work. This makes it easy to check later whether the maintenance work was performed correctly when problems such as product defects or equipment trouble occur.

[0077] The control unit 100 executes a process of recording the operation details of the maintenance work performed in the work steps as a log in the memory unit 102, either independently of each step in the maintenance method for performing maintenance on the cutting device 10, or as part of internal processing.

[0078] For example, during maintenance work, when the selection of a move button on the display monitor 56 configured by a touch panel is accepted in accordance with detailed procedure 821 of the maintenance procedure 82 in the manual 80 that the operator 70 has referred to, the operation of moving to the transfer area is recorded as a log in the storage unit 102. During maintenance work, when the selection of a blow button on the display monitor 56 configured by a touch panel is accepted in accordance with detailed procedure 822 of the maintenance procedure 82 in the manual 80 that the operator 70 has referred to, the operation of spraying water and air from the holding table 18 is recorded as a log in the storage unit 102. During maintenance work, when the operation of scrubbing the holding surface of the holding table 18 with Arkansas is accepted in accordance with detailed procedure 823 of the maintenance procedure 82 in the manual 80 that the operator 70 has referred to, the operation of scrubbing the holding surface of the holding table 18 is recorded as a log in the storage unit 102. Furthermore, when the operation of an axis constituting the cutting device 10 is accepted, it is recorded as a log in the storage unit 102. Furthermore, when an ON / OFF operation of various sensors is received, it is recorded in the storage unit 102 as a log.

[0079] By recording the details of the operations performed during maintenance work as a log in the memory unit 102, it is possible to easily check later whether the maintenance work was performed correctly when a problem such as a product defect or equipment trouble occurs.

[0080] [Confirmation step] The operator 70 checks whether the type of manual 80 recorded in the memory unit 102 in the reading step matches the maintenance work performed in the work step from the video recorded in the memory unit 102 in the work step.

[0081] For example, when the maintenance confirmation button is selected on the display monitor 56, which is composed of a touch panel, the control unit 100 displays on the display monitor 56 identification information indicating the type of manual 80 recorded in the reading step and the imaging data of the video of the maintenance work recorded in the work step.

[0082] The operator 70 compares the procedure 82 indicated by the type of manual 80 referred to during the maintenance work with the procedure of the maintenance work being performed in the video of the maintenance work recorded in the work steps.

[0083] For example, the operator 70 compares whether the procedure for ejecting the fluid 301 from the holding table 18 shown in the detailed procedure 822 included in the procedure 82 of the manual in Figure 3 matches the procedure for ejecting the fluid 301 from the holding table 18 shown in the video 201 included in the video 200 in Figure 2.

[0084] If the procedure for ejecting fluid 301 from holding table 18 shown in detailed procedure 822 included in procedure 82 of the manual in Fig. 3 matches the procedure for ejecting fluid 301 from holding table 18 shown in video 201 included in video 200 in Fig. 2, operator 70 determines that the type of manual 80 recorded in the reading step matches the maintenance work performed in the work step. This makes it possible to confirm that operator 70 performed the maintenance work in accordance with the correctly selected manual.

[0085] If the procedure for ejecting fluid 301 from holding table 18 shown in detailed procedure 822 included in procedure 82 of the manual in FIG. 3 does not match the procedure for ejecting fluid 301 from holding table 18 shown in video 201 included in video 200 in FIG. 2, operator 70 determines that the type of manual 80 recorded in the reading step does not match the maintenance work performed in the work step. This makes it possible to confirm that operator 70 performed the maintenance work according to an incorrectly selected manual. This makes it possible to confirm that the manual 80 referenced during the maintenance work is correct and that the performed maintenance procedure is correct.

[0086] In the above embodiment, the operator 70 checks whether the type of manual 80 recorded in the storage unit 102 in the reading step matches the maintenance work performed in the work step from the video recorded in the storage unit 102 in the work step, but this is not limited to this. The process of determining whether the type of manual 80 recorded in the storage unit 102 in the reading step matches the maintenance work performed in the work step may be performed by the control unit 100 from the video recorded in the storage unit 102 in the work step.

[0087] For example, the control unit 100 can confirm the maintenance work performed in the work step by performing image analysis of the video recorded in the storage unit 102 in the work step. Then, the control unit 100 can execute a process to determine whether the type of manual 80 recorded in the storage unit 102 in the reading step matches the maintenance work performed in the work step and subjected to image analysis. This can improve the processing accuracy of the confirmation in the confirmation step and reduce the confirmation time.

[0088] Next, each step of a maintenance method for performing maintenance on the cutting device 10 according to another embodiment will be described. The maintenance method for performing maintenance on the cutting device 10 according to another embodiment further includes a notification step in addition to a reading step and an operation step. The contents of the reading step and the operation step are the same as those in the above-described embodiment, and therefore description thereof will be omitted.

[0089] [Notification step] The control unit 100 determines, based on the linking data, whether the maintenance procedure corresponding to the identification code read in the reading step matches the log of the maintenance work performed in the work step. The linking data links the identification code read in the reading step with the maintenance work of the cutting device 10 performed in the work step. If the result of determining whether the maintenance procedure corresponding to the identification code read in the reading step matches the log of the maintenance work performed in the work step shows that they do not match, an error is reported.

[0090] 4 is a diagram showing an example of the linking data 600 recorded in the storage unit 102. The linking data 600 is recorded in advance in the storage unit 102 before the maintenance method is performed. The linking data 600 is recorded in the storage unit 102, but this is not a limitation, and the linking data 600 may also be recorded in the storage unit of an external device.

[0091] The linking data 600 associates a maintenance task, an identification code, and a maintenance procedure to be performed. The identification code included in the linking data 600 is information corresponding to the identification code 81 shown in the manual 80. In the linking data 600 shown in FIG. 4, "A001" is recorded as the identification code. The maintenance task is information indicating the type of manual 80 corresponding to the identification code 81. In the linking data 600 shown in FIG. 4, "cleaning the holding table" is recorded as the maintenance task. The maintenance procedure included in the linking data 600 is information corresponding to the maintenance procedure 82 shown in the manual. In the linking data 600 shown in FIG. 4, "1. Select movement button" and "2. Select blow button" are recorded as the maintenance procedure 82.

[0092] The control unit 100 determines whether the maintenance procedure 82 corresponding to the identification code 81 read in the reading step matches the log of the maintenance work performed in the work step. The information in the log of the maintenance work performed in the work step is information that indicates the operation content of the maintenance work performed in the work step. The information in the maintenance work log is appropriately recorded in the memory unit 102. The information in the maintenance work log may also be recorded in the memory unit of an external device.

[0093] For example, if the identification code 81 read in the reading step is "A001," the control unit 100 checks "2. Select blow dry button" as the maintenance procedure corresponding to "A001" based on the linking data 600 shown in Fig. 4. If information about the button selected when input of the blow dry button was received on the display monitor 56 configured as a touch panel is recorded as a log in the storage unit 102, the control unit 100 determines that the maintenance procedure corresponding to the identification code 81 read in the reading step matches the log of the maintenance work performed in the work step. If the maintenance procedure corresponding to the identification code 81 read in the reading step matches the log of the maintenance work performed in the work step, no error is reported.

[0094] For example, if the identification code 81 read in the reading step is "A001," the control unit 100 confirms "2. Select blow dry button" as the maintenance procedure corresponding to "A001" based on the linking data 600 shown in FIG. 4. If information about the selected button is recorded as a log in the storage unit 102 when input of a button other than the blow dry button is received on the display monitor 56 configured as a touch panel, the control unit 100 determines that the maintenance procedure corresponding to the identification code 81 read in the reading step does not match the log of the maintenance work performed in the work step. If it is determined that the maintenance procedure corresponding to the identification code 81 read in the reading step does not match the log of the maintenance work performed in the work step, the control unit 100 notifies an error.

[0095] The error notification in the notification step is performed by a notification unit configured by the display monitor 56, the indicator lamp 57, the speaker 58, etc. For example, the error notification is performed by displaying an error message on the display monitor 56, by changing the lighting state of the indicator lamp 57, or by emitting a voice or alarm sound from the speaker 58. The error notification is performed by the control unit 100, but is not limited to this and may be performed by an external device.

[0096] If a log is recorded that is different from the maintenance procedure corresponding to the identification code 81 indicated in the manual 80 referred to during the maintenance work and the work that should have been performed during the maintenance work, an error is reported. The operator 70 who is notified of the error can easily and quickly understand that a maintenance procedure 82 that is different from the work that should have been performed during the maintenance work has been performed. This allows the operator 70 to confirm that the performed maintenance procedure is correct.

[0097] The embodiments of the present invention are not limited to the above-described embodiments and modifications, and may be variously changed, substituted, or modified without departing from the spirit of the technical idea of the present invention. Furthermore, if the technical idea of the present invention can be realized in a different way due to technological advances or other derived technologies, it may be implemented using that method. Therefore, the claims cover all embodiments that may fall within the scope of the technical idea of the present invention. [Industrial Applicability]
