Further, it is possible to supervise the photographing of the parts to be inspected and to store the photographing results in the general-purpose terminal. Therefore, it is difficult to produce an excellent effect of inspecting individual differences caused by the worker.

A device inspection system according to an embodiment of the present invention will be described with reference to Figs. 1 to 7 .
(summary of device inspection system)
Fig. 1 is a block diagram showing a device inspection system showing an embodiment of the present invention. As shown in FIG. 1, the inspection system is composed of a client, a cloud (storage device) 34, a support promotion unit 32, and a management company 36. A device 12 to be inspected is provided in the client. The cloud 34 has the function of storing data for device inspection. The support promotion unit 32 supports the client that has the device to be inspected. The management company 36 signs a use contract with the support promotion unit 32 to manage the materials for device inspection stored in the cloud 34.

A QR code is attached to each device installed on the client side to be inspected. Further, a QR code is attached to each component to be inspected in the components constituting the device, and each inspection region or inspection portion. In the QR code attached to each device, at least the name of the component to be inspected in the device and the name of the inspection area or the inspection site are written as materials. Further, at least the inspection items of the parts, the inspection area, or the inspection area are written as the data in the QR code attached to each part and each inspection area or inspection part.

The client inspection operator logs in to the cloud 34 from the smart phone 20 or the like as a general terminal, and downloads necessary information. In addition, before that, the application (APP) can be downloaded from the Internet (for example, the cloud managed by Apple, Google, etc.). Thereby, the smartphone 20 can be used as an inspection terminal. That is, by using the smartphone 20 that has downloaded the necessary data from the cloud 34 (and, if necessary, downloading the application from the Internet), the device or the component attached to the inspection object and the inspection area or inspection site are attached. When the QR code is taken, an instruction related to the inspection content is obtained. Then, the instruction is displayed on the smartphone 20 to perform necessary inspection. Thereafter, the inspection operator sends the inspection result from the smartphone 20 to the cloud 34. In addition, in the inspection of a certain device, if the QR code of other devices is read, the display may also be warned to pay attention. Moreover, the examiner can be selected after logging in from the general terminal, thereby leaving the information of the operator who checked. In addition, by using a smart phone as the inspection terminal, the feature of the smart phone can be effectively utilized, and the function (lighting function) of the smart phone can be flexibly used when the dark portion of the QR code cannot be read. Further, when the inspection terminal is updated, it can be handled only by downloading the application to the terminal. In addition, the supplementary explanation of the inspection result can be performed not only for text input but also for voice input.

Here, as a general-purpose terminal, a tablet terminal can also be used instead of the smart phone 20. In addition, a glasses-type terminal or a watch-type terminal can be used if it has a function of photographing, a function of connecting to a network (cloud), a display function of data, and an installation of an application or a data storage function.

A personal computer 38 and a printer 39 can be provided at the client side. Further, by connecting the personal computer 38 to the cloud 34, information (inspection data, etc.) of the inspection result can be obtained from the cloud. Moreover, the information obtained can be printed by the printer 39.

Here, the so-called cloud refers to the cloud computing service. Thereby, the services provided by the servers existing on the network can be utilized regardless of the server groups such as them.

In one embodiment of the invention, the information necessary for the inspection system of the device is stored in the cloud 34. Then, the necessary information is transmitted in accordance with the request from the smart phone 20 as the general terminal held by the inspection operator. Further, after the end of the inspection operation, the information of the inspection result is received from the smartphone 20 and stored in the cloud 34.

The information of the inspection results stored in the cloud 34 can be read from the client's personal computer 38 as required, or can be printed by the client's printer 39. Further, the information of the inspection result can be referred to from the support promotion unit 32.

By storing the data in the cloud 34, the data in the cloud 34 can be preserved even if the server of the client is down. Therefore, a spare server or the like is not required, so that the capacity of the server of the client can be reduced, or the server itself can be removed. As a result, the client can reduce equipment costs.

The support promotion unit 32 supports the client that has the device to be inspected. The information of the inspection results stored in the cloud 34 can be referred to from the personal computer 32A installed in the support promotion unit 32. In addition, the necessary information can be sent to the cloud 34 in association with the device check and stored in the cloud 34.

The management company 36 signs a use contract with the support promotion unit 32 to manage the device check system, that is, the management and update of the information stored in the cloud 34.
(Using the device to check the processing order of the system)
Next, the processing procedure of the device inspection system 10 will be described with reference to the flow chart of Fig. 2 .

Fig. 2A is a flow chart showing the flow of processing of the entire apparatus inspection system according to an embodiment of the present invention. As shown in FIG. 2A, first, it is connected to the cloud from a general terminal such as a smart phone and registered (S1). Then, the maintenance inspection data (S2) of the device is downloaded from the cloud. Secondly, the general terminal is input for daily inspection or monthly inspection (S3). Then, the QR code attached to the device that has been inspected is photographed by the general-purpose terminal (S4). In this way, the part to be inspected and the inspection area or inspection site among the devices to be inspected are displayed on the general-purpose terminal (S5). Check each part displayed and each inspection area or inspection area (S6). For example, inspection of temperature, pressure, wear, gap, sound, state, and the like of each part and each area or part is performed. After the inspection of all the parts and the inspection area or inspection site is completed, the universal terminal is connected to the cloud, and the information obtained by the inspection is transmitted (S7). After the transfer of the data is completed, the connection between the universal terminal and the cloud is released and the logout is performed (S8).

Next, the processing procedure relating to the inspection of the component to be inspected and the inspection area or the inspection site will be described with reference to the flow chart of FIG. 2B.

2B is a flow chart showing a flow of processing relating to inspection of a part to be inspected and an inspection area or inspection part. That is, in FIG. 2A, the steps (S7 and S8) for inspecting each of the displayed parts and each inspection area or inspection part are shown in detail. As shown in FIG. 2B, first, on the general-purpose terminal that has downloaded the necessary data from the cloud, that is, by using the general-purpose terminal that completes the above steps S1 to S6, the image is attached to the target part and the inspection area or the inspection area. QR code (S11). Here, the general terminal determines whether or not the component to be photographed and the region or the portion are the inspection target (S12), and when it is not the inspection target, the main point is displayed (S13). It is because the object to be inspected is different during daily inspection or monthly inspection, so it is displayed to avoid unnecessary inspection. When the part to be photographed and the area or part are inspected, the general-purpose terminal displays an inspection item (such as temperature, pressure, wear, gap, sound, state, etc.) corresponding to the part (S14). The inspection item is recorded in the QR code read.

The inspection operator checks each inspection item, and inputs the inspection result (for example, a result of normal, attention, abnormality, etc.) based on the determination criterion into the general-purpose terminal (S15). Here, when the inspection result input by the operator is inferior, for example, when the result of the determination of the attention or the abnormality is input (S16), the part to be inspected and the inspection area or the inspection area or the inspection area or Shooting of the inspection area (S17). By retaining the captured image as material, the third party can judge the object based on the image, and thus it is difficult to cause personal differences caused by the inspection operator.

As a result, when the input of the inspection result for one item is completed, the general terminal determines whether or not the input (and/or photographing) is completed for all the inspection items (S18). When there is an unchecked item, the general-purpose terminal returns to display an inspection item corresponding to the part and the area or the part (S14), and checks the unchecked item.

If the input (and/or shooting) is completed for all the items, the general terminal judges whether or not the inspection is completed for all the parts and the area or the part (S19). When the inspection is completed for all parts and regions or parts, the inspection operator connects the universal terminal to the cloud and logs in, and transmits the data of the inspection result to the cloud (S20). When there is an unchecked part and an area or a part, the common terminal attaches a QR code attached to the periphery of the part and the area or the part (S11), and repeats the above steps (S12 to S18).

Here, although a QR code is used as the determining means, a matrix type two-dimensional code such as a QR code may be used instead of a stacked type two-dimensional code such as a PDF417 code. Further, by using the general-purpose terminal to capture the entire device or by using a general-purpose terminal to capture a specific location of the device, the same effects and effects as those for capturing the QR code can be obtained. For the inspection of each part and area or part, a stacked type two-dimensional code such as a PDF417 code can also be used. Further, instead of taking a QR code, a general terminal can be used to photograph parts, regions, or parts.

Next, a description will be given of a case where the device inspection system is applied to each device.
(checking of the molding machine)
Here, a case where the apparatus to be inspected is the molding machine 50 will be described with reference to FIGS. 3 and 4 . In Fig. 3, the molding machine 50 is shown in a front view.

When the inspection operator uses the smart phone 20 to photograph the QR code attached to the molding machine 50, the smart phone 20 displays the parts to be inspected, the inspection area, or the inspection site in a list.

That is, when the QR code attached to the hydraulic unit 56 is photographed, the amount of oil and the oil temperature in the hydraulic tank 56A, the pressure of the hydraulic pump 56B, and the effect on the oil filter are displayed on the smart phone 20. The pressure of the device 56C is used as an inspection item. Moreover, when the QR code attached to the release agent tank 58 is photographed, the amount of the release agent stored in the release agent tank 58 is displayed on the smart phone 20 as an inspection item. Further, when the QR code attached to the peripheral portion of the release agent injector 60 is photographed, the hole clogging of the release agent injector 60 and the leakage from the release agent injector 60 are displayed on the smartphone 20. The liquid comes as an inspection item. Moreover, when the QR code attached to the peripheral portion of the gate bar 62 is imaged, the movement of the gate bar 62 is displayed on the smartphone 20 as an inspection item. Moreover, when the QR code attached to the flask 52 is photographed, the movement of the knockout pin 64 is displayed on the smartphone 20 as an inspection item. Further, when the QR code attached to the inflatable can portion 66 is photographed, the abrasion and clogging of the inflation nozzle 68 and the abrasion of the sliding shutter 70 are displayed on the smart phone 20 as an inspection item.

Here, the molding machine 50 will be described. As shown in FIG. 3, the molding machine 50 is a device for molding the casting sand in the upper and lower flasks 52. The upper and lower flasks 52 are arranged side by side in two pairs. In the flask 52 disposed on the left side of the drawing, the foundry sand is pressed. The molded mold is taken out in the flask 52 disposed on the right side of the drawing. These flasks 52 are arranged to be rotated by the flask rotation mechanism 59 around the rotation axis 59X in the vertical direction of the apparatus, and the left and right positions in the figure can be replaced. Further, a sand blowing port is formed on the side wall of each of the flasks 52.

The upper and lower flasks 52 are movable by the cylinder 57 and are moved up and down along the connecting shaft 51 which is axially oriented in the vertical direction of the apparatus. Further, a model plate is sandwiched between the upper and lower flasks 52. Further, a squeeze plate (also referred to as a squeeze board) 55 may be inserted into the upper opening of the upper flask 52 and the lower opening of the lower flask 52. The pressing plate 55 can be raised and lowered by the hydraulic cylinder 54. That is, the hydraulic cylinder 54 is used for driving the casting sand in the flask 52. The hydraulic cylinder 54 is connected to the hydraulic unit 56 shown in Fig. 4 . The hydraulic unit 56 is a component to be inspected in advance in the molding machine 50, and the hydraulic unit 56 is provided with a QR code (not shown).

The hydraulic unit 56 includes not only the hydraulic tank 56A that stores the oil supplied to the hydraulic cylinder 54 (see FIG. 3) but also the oil of the hydraulic tank 56A to the hydraulic cylinder 54 (see FIG. 3).

The pressure caused by the pump 56B and the pressure acting on the oil filter 56C serve as inspection items.

The amount of oil in the hydraulic tank 56A is confirmed by the oil level gauge 56D which is visually provided on the hydraulic tank 56A. The inspection operator determines whether or not the oil in the hydraulic tank 56A is added to the preset reference oil level, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal. Here, when the result of the determination to be noticed or abnormal is input, the photographing of the oil level gauge 56D is displayed on the smart phone 20, so that the operator performs the photographing of the oil level meter 56D based on the display of the smart phone 20. . Further, the pressure caused by the hydraulic pump 56B is confirmed not only by the hydraulic pump 56B but also by visually reading the pressure gauge 56E provided on the hydraulic pump 56B. The inspection operator determines whether the value of the pressure gauge 56E indicates a preset pressure value, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal.

The pressure acting on the oil filter 56C not only activates the hydraulic pump 56B but also confirms it by visually observing the pressure gauge 56F provided on the oil filter 56C. The inspection operator determines whether or not the table of the pressure gauge 56F is within a predetermined range, and inputs the determination result (inspection result) to the smartphone 20. Further, the temperature of the oil in the hydraulic tank 56A is confirmed by the oil temperature gauge 56G which is visually provided on the hydraulic tank 56A. The inspection operator determines whether or not the value of the oil temperature gauge 56G is equal to or lower than a preset temperature, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal.

By checking the amount of oil in the hydraulic tank 56A, the pressure caused by the hydraulic pump 56B, the pressure acting on the oil filter 56C, and the temperature of the oil of the hydraulic tank 56A, maintenance is performed, and the hydraulic cylinder 54 can be expected ( Referring to Figure 3), the cast sand is well pressed and the cast sand is well pressed. Further, if the captured image is retained as data, if necessary, the third party can judge the object based on the image, and thus it is difficult to cause an individual difference caused by the inspection operator.

Further, as shown in FIG. 3, the molding machine 50 includes a release agent tank 58 for storing a release agent, and a release agent for spraying the release agent stored in the release agent tank 58 into the flask 52.

Further, although the detailed description is omitted, in the molding machine 50, in order to make the sand blowing port of the side wall of the flask 52 abut against the inflation nozzle 68, the sand box 52 may be filled with sand from the inflation nozzle 68, and provided with A mechanism for moving the flask 52. The inflated can portion 66 is a component to be inspected in advance in the molding machine 50, and has a QR code (not shown) on the inflating can portion 66.

Since the inflated can portion 66 is a component to be inspected, if the QR code attached to the inflated can portion 66 is photographed, the abrasion and clogging of the inflation nozzle 68 and the wear of the sliding shutter 70 are displayed on the smart phone 20. As an inspection item.

The wear and clogging of the inflation nozzle 68 was confirmed by visual inspection. The inspection operator determines whether the inflation nozzle 68 does not have wear and clogging exceeding the allowable limit, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal. Here, when the result of the determination of the attention or the abnormality is input, the shooting of the situation in which the wear and the clogging are promoted is displayed on the smartphone 20, so that the inspection operator photographs the situation based on the display of the smartphone 20. Moreover, the wear of the sliding shutter 70 is also confirmed by visual inspection. The inspection operator determines whether or not the sliding shutter 70 does not wear beyond the allowable limit, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal. Here, when the result of the determination of the attention or the abnormality is input, the shooting of the wear condition is displayed on the smartphone 20, and the operator is photographed according to the display of the smartphone 20.

By inspecting and maintaining the wear and clogging of the inflation nozzle 68, the cast sand inside the aeration tank portion 66 is well filled in the mold molding space. Moreover, since the sliding shutter 70 is satisfactorily actuated by checking the wear of the sliding shutter 70, it is expected that the casting sand is favorably supplied to the inside of the inflatable can portion 66.

After the inspection of all the inspection target parts related to the molding machine 50 is completed, the inspection operator connects the universal terminal to the cloud and logs in, and transmits the inspection result data to the cloud.

Here, although the boxless molding machine will be described, the same inspection is performed for the box molding machine.

(Check of granulator)
Next, a case where the apparatus to be inspected is used as the granulator 76 will be described with reference to Fig. 5 . In Fig. 5, the granulator 76 is shown in a front view. The granulator 76 is provided with a QR code (not shown).

Before the inspection of the granulator 76, the inspection operator logs in to the cloud 34 from the smartphone 20 as a general terminal, and downloads the necessary materials. In addition, before that, you can download applications from the Internet (such as Apple, Google, and other cloud managed by Google). Secondly, whether the daily check or the monthly check is entered in the smart phone 20 is divided. Thereby, the smartphone 20 can be used as an inspection terminal. Here, the situation of daily inspection will be described.

In the granulator 76, the pair of rolls 82 and the feeder screw 80 are components to be inspected. When the inspection operator uses the smartphone 20 to photograph the QR code attached to the granulator 76, the components to be inspected are displayed on the smartphone 20 in a list. Further, a QR code is attached to the peripheral portions of the pair of rollers 82 and the feeder screw 80.

That is, when the QR code attached to the peripheral portion of the pair of rollers 82 is photographed, the abrasion and the abnormal sound in the pair of rollers 82 and the pressure between the pair of rollers 82 are displayed on the smartphone 20 as Check item. Further, when the QR code attached to the peripheral portion of the feeder screw 80 is photographed, the abrasion and sound (unvoice) of the feeder screw 80 are displayed on the smartphone 20 as an inspection item.

Here, the granulator 76 will be described. The granulator 76 shown in Fig. 5 is a device which pressurizes and solidifies the supplied raw material to form a granulated product (crush). The granulator 76 includes a hopper 78, a feeder screw 80 provided inside the hopper 78, and a pair of rollers 82 provided on the lower side of the hopper 78.

The cross sections orthogonal to the rotation axis of the pair of rolls 82 are formed in a ring shape, and are arranged in parallel in the horizontal direction so as to be parallel to each other so as to be parallel to each other. A plurality of concave pockets (not shown) are formed on the outer circumferential surfaces of the pair of rollers 82. The bag system formed on each outer peripheral surface of the pair of rolls 82 is formed on each outer peripheral surface at a position that matches each other in the circumferential direction.

Further, a spiral fin (not shown) is provided around the shaft portion (rotation shaft) of the feeder screw 80 provided inside the hopper 78. A variable speed motor 86 that is used for the rotational driving of the feeder screw 80 is connected to the shaft portion of the feeder screw 80 via the driving force transmission mechanism 84. The feeder screw 80 is rotated by the rotational driving force of the variable speed motor 86 to press the raw material in the hopper 78 between the pair of rollers 82.

On the other hand, a variable speed motor (not shown) that is used for the rotational driving of the roller 82 is connected to the shaft portion of the pair of rollers 82 via a driving force transmission mechanism (not shown). Further, the driving force of the variable speed motor is converted into two electric powers which are opposite to each other by the driving force transmission mechanism. The pair of rollers 82 are rotated in opposite directions by the rotational driving force of the variable speed motor, and the raw materials supplied to each other are press-cured and compressed to form granules.

Since the pair of rollers 82 are the inspection target parts, when the QR code attached to the peripheral portion of the pair of rollers 82 is photographed, the wear and the abnormal sound of the pair of rollers 82 and a pair are displayed on the smart phone 20. The pressure between the rolls 82 serves as an inspection item. The wear and abnormal sound of the pair of rollers 82 are confirmed by viewing. The inspection operator determines the degree of wear and abnormal sound of the pair of rollers 82, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal. Regarding the wear, when the result of the judgment of the attention or the abnormality is input, the shooting of the wear condition is displayed on the smartphone 20, so that the operator checks the situation based on the display of the smartphone 20. Regarding the sound (unnatural sound), when the result of the judgment of the attention or the abnormality is input, the recording of the sounding of the abnormal sound is displayed on the smart phone 20, so that the checking operator performs the recording according to the display of the smart phone 20. By retaining the recorded material, the third party can judge the situation based on the recorded material, and thus it is difficult to cause personal differences caused by the inspection operator. The pressure between the pair of rollers 82 is confirmed by visually reading a pressure gauge (not shown). The inspection operator determines whether the pressure display value between the pair of rollers 82 is a pressure value assumed in advance, and inputs the determination result (inspection result) into the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal.

Further, since the feeder screw 80 is a component to be inspected, if the QR code attached to the peripheral portion of the feeder screw 80 is photographed, the wear and the difference of the feeder screw 80 are displayed on the smartphone 20. The sound comes as an inspection item. The wear and abnormal sound of the feeder screw 80 are confirmed by viewing. The inspection operator determines the degree of wear and abnormal sound of the feeder screw 80, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal. Regarding the wear, when the result of the judgment of the attention or the abnormality is input, the photographing of the wear condition is displayed on the smartphone 20, so that the inspection operator photographs the situation based on the display of the smartphone 20. Regarding the sound (unnatural sound), when the result of the judgment of the attention or the abnormality is input, the recording of the sounding of the abnormal sound is displayed on the smart phone 20, so that the checking operator performs the recording according to the display of the smart phone 20.

By inspecting and maintaining the wear and noise of the feeder screw 80, the material in the hopper 78 can be squeezed between the pair of rollers 82 in an appropriate amount. By this operation, an appropriate amount of raw materials is used to form granules of an appropriate shape. Further, by checking the pressure setting value between the pair of rollers 82 and the pressure display value between the pair of rollers 82 and maintaining them, it is expected that the density of the granulated material can be favorably maintained.

After the inspection of all the inspection target parts related to the granulator 76 is completed, the inspection operator connects the universal terminal to the cloud and logs in, and transmits the inspection result data to the cloud.

(Check of the brush grinding device)
Next, a case where the apparatus to be inspected is the brush polishing apparatus 90 will be described with reference to Figs. 6 and 7 . In Fig. 6, the brush polishing device 90 is shown in a front view, and in Fig. 7, the brush polishing device 90 is shown in a side view.

Before the inspection of the brush polishing device 90, the inspection operator logs in to the cloud 34 from the smart phone 20 as a general terminal, and downloads the necessary materials. In addition, before that, you can download applications from the Internet (such as Apple, Google, and other cloud managed by Google). Secondly, whether the daily check or the monthly check is entered in the smart phone 20 is divided. Thereby, the smartphone 20 can be used as an inspection terminal. Here, the situation of daily inspection will be described.

In the brush polishing device 90, the drive motor 98, the brush 96, the coolant circulation unit 100, and the mounting jig 94 are parts to be inspected, and an inspection area or an inspection site. When the inspection operator photographs the QR code attached to the brush polishing device 90 by the smartphone 20, the components to be inspected, the inspection area, or the inspection site are displayed on the smartphone 20 in a list.

As shown in FIG. 7, the brush polishing device 90 includes a revolving table 104 disposed in a range including the polishing chamber 102. The revolution table 104 is rotationally driven by a motor 106. Further, on the revolution table 104, a plurality of (two in the present embodiment) rotation tables 108 arranged at equal intervals in the circumferential direction are disposed. When the rotation table 108 is disposed at a predetermined position of the polishing chamber 102 (a position below the brush 96 to be described later), the rotation table 108 is rotationally driven by the driving force of the motor 110.

A mounting jig 94 to which an object to be processed is attached to the installation portion 92 is provided on the rotation table 108. On the other hand, in the polishing region of the polishing chamber 102, a brush 96 is provided at a height position on the upper side of the revolution table 104 and the rotation table 108. The brush 96 is disposed such that its hair tip is directed downward, and is rotationally driven by the drive motor 98 shown in FIGS. 6 and 7. As a result, the brush 96 shown in FIG. 7 is polished while being in contact with the object to be processed attached to the installation portion 92 by the attachment jig 94, and the surface of the object to be processed is polished. In addition, the brush polishing device 90 includes not only a mechanism (not shown) for injecting a coolant to the contact portion between the brush 96 and the object to be processed, but also a peripheral portion thereof, and a coolant circulation unit 100 that circulates the coolant.

Since the drive motor 98 is a component to be inspected in advance in the brush polishing device 90, a QR code (not shown) is provided around the drive motor 98. When the QR code attached to the peripheral portion of the drive motor 98 is imaged, the current value, the abnormal sound, and the vibration of the drive motor 98 are displayed on the smartphone 20 as an inspection item.

The current value of the drive motor 98 is confirmed by a visual galvanometer, and the abnormal sound and vibration of the drive motor 98 are confirmed by viewing. The inspection operator determines whether or not the current value of the drive motor 98 is a predetermined current value and the degree of noise and vibration of the drive motor 98, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal. Regarding the sound (unnatural sound), when the result of the judgment of the attention or the abnormality is input, the recording of the sounding of the abnormal sound is displayed on the smart phone 20, so that the checking operator performs the recording according to the display of the smart phone 20.

Thereby, the presence or absence of the failure of the basic function of the brush polishing device 90 is confirmed in advance. Here, by checking the current value, the noise, and the vibration of the drive motor 98 and maintaining it, it is expected that the brush 96 shown in Fig. 7 is appropriately rotated, and the surface of the object to be processed is well polished by the brush 96. . Further, by retaining the recorded material, the third party can judge the situation based on the recorded material, and thus it is difficult to cause personal differences caused by the inspection operator.

In addition, since the brush 96 shown in FIG. 7 is a component to be inspected which is set in advance in the brush polishing device 90, a QR code (not shown) is attached to the peripheral portion of the brush 96. Further, when the QR code attached to the peripheral portion of the brush 96 is photographed, the abrasion of the brush 96 is displayed on the smartphone 20 as an inspection item.

The abrasion of the brush 96 was confirmed by visual inspection. The inspection operator determines the degree of wear of the brush 96, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal. Regarding the degree of wear, when the result of the determination of the attention or the abnormality is input, the shooting of the wear condition is displayed on the smartphone 20, so that the operator checks the condition of the smartphone 20 based on the display. By inspecting and maintaining the abrasion of the brush 96, it is expected that the surface of the object to be processed is precisely ground by the brush 96. Further, by retaining the captured image as material, the third party can judge the degree of wear based on the image, and thus it is difficult to cause personal differences caused by the inspection operator.

Since the coolant circulation unit 100 is also a component to be inspected which is set in advance in the brush polishing device 90, a QR code (not shown) is provided in the peripheral portion of the coolant circulation unit 100. When the QR code attached to the peripheral portion of the coolant circulation unit 100 is imaged, the circulation of the coolant is displayed on the smartphone 20 as an inspection item.

The circulation of the coolant is confirmed by visually operating the coolant circulation unit 100. The inspection operator determines whether or not the circulation of the coolant is normally performed, and inputs the determination result (inspection result) to the smartphone 20. The input to the smart phone 20 is based on the determination criteria, and is input into three types of normal, attention, and abnormal. When the input operation state is the result of the determination or the abnormality determination result, the smart phone 20 is displayed on the smart phone 20, so that the operator is photographed in accordance with the display of the smart phone 20. When the circulation of the coolant is checked and maintained, when the object to be processed is polished by the brush 96, the cooling by the coolant is favorably performed. Further, by retaining the captured image as material, the third party can judge the state of the circulation of the coolant based on the image, and thus it is difficult to cause an individual difference caused by the inspection operator.

Further, since the attachment jig 94 is also a component to be inspected in advance in the brush polishing device 90, a QR code (not shown) is provided around the attachment jig 94. Further, when the QR code attached to the peripheral portion of the mounting jig 94 is photographed, the abrasion of the mounting jig 94 is displayed on the smartphone 20 as an inspection item.
