When the code is photographed, the function of displaying the inspection screen corresponding to the part to be inspected to which the two-dimensional code is attached is displayed on the general-purpose terminal, and the instruction on the inspection screen indicates the part to be inspected. The inspection results are divided into three categories: normal, caution required, and abnormal, and a function that prompts input and a function that prompts input of supplementary explanations are included. If caution or abnormality is input, the inspection target is applicable. It is characterized by having a function of urging the photographing of the component to be photographed and saving the photographing result in the general-purpose terminal, and a function of transmitting the inspection result to a server on the network.

In this way, when an input is made that the inspection result requires caution or is abnormal, the parts to be inspected are prompted to be photographed and the photographed result is saved in the general-purpose terminal, so that individual differences among inspection workers are less likely to occur. .. In addition, by entering the supplementary explanation on a general-purpose terminal, the entered contents can be viewed on the office personal computer via the network. For example, if it is written as "Please arrange for XX", the person in the office can make the arrangement as soon as possible. Further, for example, if "Adjustment of maintenance schedule" is entered, a person in the office can adjust the maintenance schedule as soon as possible.

The device inspection system of the present invention according to the third aspect is characterized in that, in the first form or the second form, the two-dimensional code is a QR code.

The device inspection system according to one embodiment of the present invention will be described with reference to FIGS. 1 to 7.
(Overview of equipment inspection system)
FIG. 1 shows a block diagram showing an apparatus inspection system according to one embodiment of the present invention. As shown in FIG. 1, this inspection system is composed of a customer, a cloud (storage device) 34, a support promotion unit 32, and a management company 36. A device 12 to be inspected is installed at the customer's site. The cloud 34 has a function of storing data for device inspection. The support promotion unit 32 supports the customer in which the device to be inspected is installed. The management company 36 concludes a usage contract with the support promotion department 32 and manages the data for device inspection stored in the cloud 34.

A QR code is affixed to each device to be inspected installed at the customer's site. In addition, a QR code is also affixed to each part to be inspected and each inspection area or inspection location among the parts constituting the device. In the QR code affixed to each device, at least the name of the part to be inspected in the device and the inspection area or inspection point is written as data. In addition, at least the inspection items of the parts and the inspection area or the inspection place are written as data in the QR code attached to each part and each inspection area or inspection place.

The inspection worker at the customer's site logs in to the cloud 34 from a smartphone 20 or the like as a general-purpose terminal and downloads necessary data. Prior to this, the application is downloaded from the network (for example, the cloud managed by Apple Inc. or Google Inc.) as needed. As a result, the smartphone 20 can be used as an inspection terminal. That is, with the smartphone 20 that has downloaded the necessary data from the cloud 34 (and downloaded the application from the network as needed), the device or part to be inspected and the QR code affixed to the inspection area or inspection location are photographed. By doing so, you will get instructions about the inspection contents. Then, the instruction is displayed on the smartphone 20 and necessary inspections are performed. After that, the inspection worker transmits the inspection result from the smartphone 20 to the cloud 34. If the QR code of another facility is read during the inspection of one facility, a warning display can be displayed to call attention. In addition, an inspector can be selected after logging in from a general-purpose terminal, whereby data on who the inspected worker is can be left. In addition, by using the smartphone as an inspection terminal, it is possible to utilize the function (lighting function) of the smartphone when inspecting in a dark place where the QR code cannot be read by taking advantage of the characteristics of the smartphone. Furthermore, even when the inspection terminal is updated, it is possible to respond by simply downloading the application to the terminal. In addition, the supplementary explanation of the inspection result can be input not only by characters but also by voice.

Here, as a general-purpose terminal, a tablet terminal may be used instead of the smartphone 20. In addition, if there is a shooting function, a function of connecting to a network (cloud), a function of displaying data, and a function of installing an application and saving data, a glasses-type terminal, a wristwatch-type terminal, or the like can be used.

A personal computer 38 and a printer 39 can be installed at the customer's site. Then, by connecting the personal computer 38 and the cloud 34, information on the inspection result (inspection data and the like) can be acquired from the cloud. Further, the acquired information can be printed by the printer 39.

Here, the cloud refers to a cloud computing service. As a result, the services provided by the servers existing on the network can be used without being aware of those servers.

In one embodiment of the present invention, the cloud 34 stores data necessary for the device inspection system. Then, at the request of the smartphone 20 as a general-purpose terminal possessed by the inspection worker, necessary data is transmitted. Further, after the inspection work is completed, the inspection result information is received from the smartphone 20 and stored in the cloud 34.

The inspection result information stored in the cloud 34 can be referred to from the customer's personal computer 38, and can be printed by the customer's printer 39, upon request. In addition, the information on 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 is preserved even if the customer's server goes down. Therefore, since there is no need for a backup server or the like, the capacity of the customer's server can be reduced or the server itself can be eliminated. As a result, the customer can reduce the equipment cost.

The support promotion unit 32 supports the customer in which the device to be inspected is installed. Information on 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, necessary information related to the device inspection can be transmitted to the cloud 34 and stored in the cloud 34.

The management company 36 concludes a usage contract with the support promotion unit 32, manages the device inspection system, that is, manages and updates the information stored in the cloud 34.
(Processing procedure using the equipment inspection system)
Next, the processing procedure using the apparatus inspection system 10 will be described with reference to the flowchart of FIG.

FIG. 2A is a flowchart showing an overall processing flow of the apparatus inspection system according to one embodiment of the present invention. As shown in FIG. 2A, first, a general-purpose terminal such as a smartphone connects to the cloud and logs in (S1). Then, the data for maintenance and inspection of the device is downloaded from the cloud (S2). Next, the inspection category of whether it is a daily inspection or a monthly inspection is input to the general-purpose terminal (S3). Subsequently, the QR code affixed to the device to be inspected is photographed with a general-purpose terminal (S4). Then, the parts to be inspected and the inspection area or the inspection location in the device to be inspected are displayed on the general-purpose terminal (S5). Inspect each displayed part and each inspection area or inspection location (S6). For example, the temperature, pressure, wear, gap, sound, condition, etc. of each part and each area or place are inspected. When the inspection of all parts and inspection areas or inspection points is completed, the general-purpose terminal is connected to the cloud and the data acquired by the inspection is transferred (S7). When the data transfer is completed, the connection between the general-purpose terminal and the cloud is canceled and the user logs out (S8).

Next, the processing procedure for inspecting the parts to be inspected and the inspection area or inspection location will be described with reference to the flowchart of FIG. 2B.

FIG. 2B is a flowchart showing a processing flow for inspection of parts to be inspected and inspection areas or inspection points. That is, in FIG. 2A, the steps (S7 and S8) for inspecting each of the displayed parts and each inspection area or inspection location are shown in detail. As shown in FIG. 2B, first, the necessary data was downloaded from the cloud and attached to the general-purpose terminal, that is, the target parts and the inspection area or the periphery of the inspection location in the general-purpose terminal that completed steps S1 to S6. Take a picture of the QR code with a general-purpose terminal (S11). Here, the general-purpose terminal determines whether or not the part, area, or location to be photographed is subject to inspection (S12), and if it is not subject to inspection, displays that fact (S13). This is displayed to avoid unnecessary inspections because the inspection target differs depending on whether it is a daily inspection or a monthly inspection. When the part and area or place to be photographed are to be inspected, the general-purpose terminal displays the inspection items (for example, temperature, pressure, wear, gap, sound, state, etc.) according to the part (S14). The inspection items are described in the read QR code.

The inspection worker inspects each inspection item and inputs the inspection result (for example, the judgment result of normality, caution required, abnormality, etc.) according to the judgment criteria to the general-purpose terminal (S15). Here, when the inspection result input by the inspection worker is not good, for example, when the judgment result of caution or abnormality is input (S16), the parts to be inspected and the inspection area or inspection are performed on the general-purpose terminal. A display prompting the photographing of the portion is made (S17). By leaving the captured image as data, a third party can judge the object based on this image, so that individual differences among inspection workers are less likely to occur.

In this way, when the input of the inspection result for one item is completed, the general-purpose terminal determines whether or not the input (and / or shooting) for all the inspection items is completed (S18). If there are uninspected items, the general-purpose terminal returns to displaying the inspection items according to the parts and areas or locations (S14), and inspects the uninspected items.

When the input (and / or shooting) for all the items is completed, the general-purpose terminal determines whether or not the inspection for all the parts and areas or locations is completed (S19). When the inspection of all parts and areas or parts is completed, the inspection worker connects the general-purpose terminal to the cloud, logs in, and transmits the inspection result data to the cloud (S20). If there is an uninspected part, area or part, the QR code affixed to the periphery of the part, area or part is photographed with a general-purpose terminal (S11), and the above steps (S12 to S18) are repeated.

Here, the QR code is used to specify the device, but a stack type two-dimensional code such as the PDF417 code may be used instead of the matrix type two-dimensional code such as the QR code. It is also possible to obtain the same action and effect as shooting a QR code by shooting the entire device with a general-purpose terminal or shooting a specific location of the device with a general-purpose terminal. Is. Similarly, a stack type two-dimensional code such as a PDF417 code may be used for inspection of each part and area or location. Further, instead of photographing the QR code, the parts and areas or locations may be photographed with a general-purpose terminal.

Next, a case where this device inspection system is applied to each device will be described.
(Inspection of molding machine)
Here, a case where the device to be inspected is the molding machine 50 will be described with reference to FIGS. 3 and 4. FIG. 3 shows a front view of the molding machine 50, and FIG. 4 shows a plan view (FIG. 4 (A)) and a front view (FIG. 4 (FIG. 4)) of the hydraulic unit 56 forming a part of the molding machine 50. B)) and side view (FIG. 4 (C)). A QR code (not shown) is attached to the molding machine 50.

Prior to the inspection of the molding machine 50, the inspection worker logs in to the cloud 34 from the smartphone 20 as a general-purpose terminal and downloads necessary data. Prior to this, the application is downloaded from the network (for example, the cloud managed by Apple Inc. or Google Inc.) as needed. Next, the inspection category of whether it is a daily inspection or a monthly inspection is input to the smartphone 20. As a result, the smartphone 20 can be used as an inspection terminal. Here, the case of daily inspection will be described.

The upper and lower casting frames 52 are arranged side by side in two pairs on the left and right. In the casting frame 52 arranged on the left side in the drawing, the casting sand is squeezed. In the casting frame 52 arranged on the right side in the drawing, the molded mold is extracted. These casting frames 52 can be swiveled around the rotation shaft 59X in the vertical direction of the device by the casting frame swivel mechanism 59, and the left and right positions in the drawing can be exchanged. Further, a sand blowing port is formed on the side wall of each casting frame 52.

The upper and lower casting frames 52 can be raised and lowered along the connecting shaft 51 whose axial direction is the vertical direction of the device by operating the cylinder 57. A match plate is sandwiched between the upper and lower casting frames 52. Further, a squeeze plate (also referred to as a squeeze board) 55 can be inserted into the upper opening of the upper casting frame 52 and the lower opening of the lower casting frame 52, respectively. The squeeze 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 casting frame 52 for squeezing. The hydraulic cylinder 54 is connected to the hydraulic unit 56 shown in FIG. The hydraulic unit 56 is a component to be inspected preset in the molding machine 50, and a QR code (not shown) is attached to the hydraulic unit 56.

The hydraulic unit 56 includes a hydraulic tank 56A for storing oil supplied to the hydraulic cylinder 54 (see FIG. 3), and a hydraulic pump that pressurizes the oil of the hydraulic tank 56A to supply the oil to the hydraulic cylinder 54 (see FIG. 3). It is equipped with 56B. Further, the hydraulic unit 56 includes an oil cleaner 56C that filters the oil pressurized by the hydraulic pump 56B. The oil cleaner 56C includes a housing provided in the oil supply path and a filtration element housed in the housing.

Since the hydraulic unit 56 is a part to be inspected, when the QR code attached to the hydraulic unit 56 is photographed, the smartphone 20 acts on the oil amount and oil temperature in the hydraulic tank 56A, the pressure by the hydraulic pump 56B, and the oil cleaner 56C. The pressure to be applied is displayed as an inspection item.

The amount of oil in the hydraulic tank 56A is confirmed by visually observing the oil level gauge 56D provided in the hydraulic tank 56A. The inspection worker determines whether or not the oil in the hydraulic tank 56A has reached the preset reference oil level, and inputs the determination result (inspection result) to the smartphone 20. Input to the smartphone 20 is divided into three categories, normal, caution required, and abnormal, based on the judgment criteria. Here, when a determination result of caution or abnormality is input, a display prompting the smartphone 20 to take a picture of the oil level gauge 56D is displayed, so that the inspection worker takes a picture of the oil level gauge 56D according to the display of the smartphone 20.
