However, since the portable terminal device has the inspection data and the like incorporated therein in advance, there is a problem that the inspection items and the inspection contents cannot be changed flexibly. In addition, since the apparatus is a dedicated apparatus, the cost is high.
A device inspection system according to a first aspect of the present invention is a device inspection system including: an apparatus, characterized in that a two-dimensional code is mounted on a member to be a preset inspection object or a peripheral portion thereof in the apparatus; and a general-purpose terminal having a camera function and being capable of connecting to a network, the general-purpose terminal having an apparatus maintenance inspection application program incorporated therein, the general-purpose terminal having: downloading device maintenance inspection data to the general-purpose terminal and displaying an instruction on inspection contents of the device on a screen of the general-purpose terminal, if the general-purpose terminal is connected to the network and logs in to a server on the network; when the two-dimensional code is imaged according to the command displayed on the general-purpose terminal in a state of disconnecting from the network, an inspection screen corresponding to a component to be inspected on which the two-dimensional code is mounted is displayed on the general-purpose terminal; storing the inspection result inputted according to the instruction of the inspection screen in the general-purpose terminal; and transmitting the check result to a storage device on the network after the connection with the network is restored.
Here, the two-dimensional code is a code having a display form of information in the horizontal direction and the vertical direction. The two-dimensional code includes a matrix two-dimensional code such as a QR code (registered trademark) and a stacked two-dimensional code such as a PDF417 barcode.
The general-purpose terminal is not a terminal specially manufactured for the device inspection system, but includes a concept of a general-purpose smartphone that can be used by an individual. The universal terminal comprises a tablet computer, a glasses type terminal and the like.
In this way, since the inspection can be performed using a general-purpose terminal, the inspection item and the inspection content can be flexibly changed. In addition, once logging in, even if communication with the network (cloud) is disconnected, the inspection can be performed using a general-purpose terminal, and therefore, the inspection can be continued even in an environment where the communication state is not good.

Detailed Description
An apparatus inspection system according to an embodiment of the present invention will be described with reference to fig. 1 to 7.
(overview of device inspection System)
Fig. 1 is a block diagram showing a device inspection system according to 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 pushing unit 32, and a management company 36. The client is provided with a device 12 to be inspected. The cloud 34 has a function of storing data for device inspection. The support pusher 32 provides support to a client provided with a device to be inspected. The management company 36 enters into a contract with the support pusher 32 to manage data for device inspection stored in the cloud 34.
QR codes are attached to devices to be inspected, which are installed in the client. Among the components constituting the apparatus, the QR code is attached to each component to be inspected and each inspection area or inspection portion. In the QR code attached to each device, at least the name of the component to be inspected and the inspection area or the inspection portion in the device is written as data. In addition, in the QR code attached to each component and each inspection area or inspection portion, at least the inspection items of the component and the inspection area or inspection portion are written as data.
The inspection worker at the client logs in to the cloud 34 from the smartphone 20 or the like as a general-purpose terminal, and downloads necessary data. Further, prior to this, applications were downloaded from a network (e.g., apple, google, etc.) as needed. This enables the smartphone 20 to be used as an inspection terminal. That is, the smartphone 20, which has downloaded necessary data (and an application program from the network as necessary), is used to capture an image of the QR code attached to the device, component, inspection area, or inspection site to be inspected, thereby obtaining an instruction regarding the inspection content. Then, the instruction is displayed on the smartphone 20 to perform a necessary examination. Thereafter, the inspection worker transmits the inspection result from the smartphone 20 to the cloud 34. In addition, when the QR code of another device is read during the inspection of a certain device, attention can be reminded by a warning display. Further, by allowing the inspector to select after logging in from the general-purpose terminal, it is possible to retain data of who has performed the inspection. Further, by using a smartphone as an inspection terminal, it is possible to utilize the functions (illumination functions) of the smartphone when inspection is performed in a dark place where the QR code cannot be read, while taking advantage of the characteristics of the smartphone. Even when the check terminal is updated, the application can be dealt with only by downloading the application to the terminal. The supplementary explanation of the examination result may be not only a character input but also a voice input.
Here, as a general-purpose terminal, a tablet terminal may be used instead of the smartphone 20. In addition, as long as the glasses-type terminal or the watch-type terminal has a photographing function, a function of connecting to a network (cloud), a function of displaying data, etc., an application program installation function, and a data storage function.
A personal computer 38 and a printer 39 may be provided at the client. Further, by connecting the personal computer 38 to the cloud 34, information of the inspection result (inspection data and the like) can be acquired from the cloud. The acquired information can be printed by the printer 39.
Here, cloud refers to a cloud computing service. This enables the use of services provided by servers existing on the network without being aware of these server groups.
In one embodiment of the present invention, data required by the present device inspection system is stored in the cloud 34. Then, the required data is transmitted in response to a request from the smartphone 20, which is a general-purpose terminal held by the inspection worker. After the inspection operation is finished, information of the inspection result is received from the smartphone 20 and stored in the cloud 34.
The information of the inspection result stored in the cloud 34 can be referred to from the personal computer 38 of the client or printed by the printer 39 of the client as required. Further, the information of the inspection result may be referred to from the support pusher 32.
By storing the data in the cloud 34, the data in the cloud 34 is preserved even if the client's server fails. Therefore, since a backup server or the like is not required, the capacity of the server of the client can be reduced, or the server itself can be eliminated. As a result, the client can reduce the equipment cost.
The support pusher 32 provides support to a client provided with a device to be inspected. The information of the inspection result stored in the cloud 34 can be referred to from the personal computer 32A provided in the support pusher 32. In addition, necessary information associated with device inspection can be sent to the cloud 34 and stored in the cloud 34.
The management company 36 enters into a contract with the support pusher 32 to manage the device inspection system, i.e., manage and update the information stored in the cloud 34.
(processing step Using device inspection System)
Next, the processing procedure of the device inspection system 10 will be described with reference to the flowchart of fig. 2.
Fig. 2A is a flowchart showing the overall process flow of the device inspection system according to the embodiment of the present invention. As shown in fig. 2A, first, a general-purpose terminal such as a smartphone is connected to the cloud and logged in (S1). Then, data for maintenance inspection of the device is downloaded from the cloud (S2). Next, the examination classification of whether daily examination or monthly examination is input to the general-purpose terminal (S3). Next, the QR code attached to the device to be inspected is photographed by the general-purpose terminal (S4). Then, the component to be inspected, the inspection area, or the inspection site in the apparatus to be inspected are displayed on the general-purpose terminal (S5). The displayed components and the inspection regions or the inspection portions are inspected (S6). For example, the temperature, pressure, wear, clearance, sound, state, and the like of each member and each region or portion are inspected. After the inspection of all the components and the inspection area or the inspection portion is completed, the general-purpose terminal is connected to the cloud and data obtained by the inspection is transmitted (S7). After the data transmission is completed, the universal terminal is disconnected from the cloud and logged out (S8).
Next, a process procedure for inspecting a component to be inspected and an inspection region or an inspection portion will be described with reference to a flowchart of fig. 2B.
Fig. 2B is a flowchart showing a process flow for inspection of a component to be inspected and an inspection region or an inspection portion. That is, the steps (S7 and S8) of inspecting each displayed component and each inspection region or inspection site in fig. 2A are shown in detail. As shown in fig. 2B, first, a QR code is captured by a general-purpose terminal, and the QR code is attached to the periphery of the inspection region or the inspection site and the target component in the general-purpose terminal in which the necessary data is downloaded from the cloud, that is, the above-described steps S1 to S6 are completed (S11). Here, the general-purpose terminal determines whether or not the part, the region, or the part to be photographed is the object to be inspected (S12), and if not, displays the determination (S13). This is because the examination object is different depending on whether it is a daily examination or a monthly examination, and is displayed in order to avoid unnecessary examinations. When the part, the region or the part to be photographed is the inspection object, the general-purpose terminal displays the inspection items (for example, temperature, pressure, wear, gap, sound, state, etc.) corresponding to the part (S14). The inspection item is described in the read QR code.
The inspection worker inspects each inspection item and inputs an inspection result (for example, a determination result such as normality, necessity of attention, abnormality) according to a determination criterion to the general-purpose terminal (S15). Here, when the inspection result input by the inspection worker is not good, for example, when a determination result requiring attention or abnormality is input (S16), a prompt to image the component to be inspected, the inspection area, or the inspection portion is displayed on the general-purpose terminal (S17). By retaining the captured image as data, a third party can determine the object from the image, and personal differences due to the inspection worker 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 the input (and/or photographing) is completed for all the inspection items (S18). When the non-inspection item exists, the general-purpose terminal returns to the step of displaying the inspection item corresponding to the component, the area, or the part thereof (S14), and performs the inspection on the non-inspection item.
When the input (and/or photographing) is completed for all items, the general-purpose terminal determines whether the inspection is completed for all the parts and areas or parts (S19). When the inspection is completed for all the components, the regions, or the parts, the inspection worker connects the general-purpose terminal to the cloud, logs in the cloud, and transmits data of the inspection result to the cloud (S20). When an unchecked component, area, or site is present, the QR code attached to the periphery of the component, area, or site is photographed by a general-purpose terminal (S11), and the above steps are repeated (S12 to S18).
Here, the QR code is used to specify the device, but a stacked two-dimensional code such as a PDF417 barcode may be used instead of a matrix two-dimensional code such as a QR code. Further, by imaging the entire device or by imaging a specific position of the device using a general-purpose terminal, the same operation and effect as those of imaging a QR code can be obtained. A stacked two-dimensional code such as PDF417 barcode can be used in the inspection of each member, region, or part as well. Instead of photographing the QR code, the component, the area, or the part may be photographed by a general-purpose terminal.
Next, a case where the 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 fig. 3 and 4A to 4C. Fig. 3 shows a front view of the molding machine 50, and fig. 4A to 4C show a plan view (fig. 4A), a front view (fig. 4B), and a side view (fig. 4C) of a hydraulic unit 56 constituting a part of the molding machine 50. The molding machine 50 is provided with a QR code (not shown).
Before the molding machine 50 is inspected, an inspection worker logs in the cloud 34 from the smartphone 20 as a general-purpose terminal, and downloads necessary data. Further, prior to this, applications were downloaded from a network (e.g., apple, google, etc.) as needed. Next, the examination classification of whether daily examination or monthly examination is input to the smartphone 20. This enables the smartphone 20 to be used as an inspection terminal. Here, a case of a daily check will be described.
In the molding machine 50, the hydraulic unit 56, the mold release agent tank 58, the mold release agent ejector 60, the gate bar 62, the flask 52, and the aeration tank portion 66 are members to be inspected, and an inspection area or an inspection site. When the inspection worker takes an image of the QR code attached to molding machine 50 using smartphone 20, the components to be inspected, the inspection area, or the inspection portion are displayed in a list on smartphone 20.
That is, when the QR code attached to the hydraulic unit 56 is photographed, the amount of oil and the temperature of oil in the hydraulic tank 56A, the pressure by the hydraulic pump 56B, and the pressure acting on the oil filter 56C are displayed as inspection items on the smartphone 20. When the QR code attached to the mold release agent tank 58 is photographed, the amount of the mold release agent stored in the mold release agent tank 58 is displayed as an inspection item on the smartphone 20. When the QR code attached to the peripheral portion of the mold release agent ejector 60 is photographed, the smartphone 20 displays the clogging of the mold release agent ejector 60 and the leakage of the liquid from the mold release agent ejector 60 as inspection items. When the QR code attached to the peripheral portion of the gate pin 62 is photographed, the movement of the gate pin 62 is displayed as an inspection item in the smartphone 20. When the QR code attached to the flask 52 is photographed, the movement of the knock-out pin 64 is displayed as an inspection item on the smartphone 20. When the QR code attached to the aeration tank portion 66 is photographed, the smartphone 20 displays the wear and clogging of the aeration nozzle 68 and the wear of the slide shutter 70 as inspection items.
Here, the molding machine 50 is explained, and as shown in fig. 3, the molding machine 50 is a device for molding the molding sand in the upper and lower flasks 52. The upper and lower flasks 52 are arranged side by side in two pairs, left and right. The molding sand is squeezed in a sand box 52 disposed on the left side in the drawing. The mold to be molded is drawn out from the flask 52 disposed on the right side in the drawing. These flasks 52 can be rotated about a vertical rotation axis 59X of the apparatus by a flask rotating mechanism 59, and the left and right positions in the drawing can be changed. Further, a sand blow-in port is formed in the side wall of each sand box 52.
The upper and lower flasks 52 can be moved up and down along the connecting shaft 51 with the vertical direction of the apparatus as the axial direction by the operation of the cylinders 57. Further, a match plate is held between the upper and lower flasks 52. Further, a squeeze plate (also referred to as a squeeze plate) 55 is insertable into each of the upper opening of the upper flask 52 and the lower opening of the lower flask 52. The compacting plate 55 may be raised and lowered by the hydraulic cylinder 54. That is, the hydraulic cylinder 54 is a member for driving the molding sand in the squeeze box 52. The hydraulic cylinder 54 is connected to a hydraulic unit 56 shown in fig. 4A to 4C. The hydraulic unit 56 is a member to be inspected which is set in advance 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 that stores oil supplied to the hydraulic cylinder 54 (see fig. 3), and a hydraulic pump 56B that pressurizes the oil in the hydraulic tank 56A to supply the oil to the hydraulic cylinder 54 (see fig. 3). The hydraulic unit 56 includes an oil filter 56C that filters oil pressurized by the hydraulic pump 56B. The oil strainer 56C includes a case provided in an oil supply path and a filter element housed in the case.
Since the hydraulic unit 56 is a component to be inspected, when the QR code attached to the hydraulic unit 56 is photographed, the amount of oil and the temperature of oil in the hydraulic tank 56A, the pressure by the hydraulic pump 56B, and the pressure acting on the oil filter 56C are displayed as inspection items on the smartphone 20.
The amount of oil in the hydraulic tank 56A is confirmed by visually checking an oil level gauge 56D provided in the hydraulic tank 56A. The inspection worker determines whether the oil in the hydraulic tank 56A reaches a preset reference oil level, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. Here, when the determination result that attention is required or an abnormality is input, the smartphone 20 displays a warning to image the oil level meter 56D, and therefore the inspection worker performs imaging of the oil level meter 56D in accordance with the display of the smartphone 20. The pressure based on the hydraulic pump 56B is confirmed by operating the hydraulic pump 56B and visually reading a pressure gauge 56E provided in the hydraulic pump 56B. The inspection worker determines whether or not 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 smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion.
The pressure acting on oil strainer 56C is confirmed by operating hydraulic pump 56B and visually observing pressure gauge 56F provided in oil strainer 56C. The inspection worker determines whether or not the meter of the pressure gauge 56F is within a predetermined range, and inputs the determination result (inspection result) to the smartphone 20. The temperature of the oil in the hydraulic tank 56A is confirmed by visually checking an oil temperature meter 56G provided in the hydraulic tank 56A. The inspection worker determines whether or not the value of the oil temperature meter 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 smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion.
By checking and maintaining the amount of oil in the hydraulic tank 56A, the pressure of the hydraulic pump 56B, the pressure acting on the oil strainer 56C, and the temperature of the oil in the hydraulic tank 56A, the hydraulic cylinder 54 (see fig. 3) operates satisfactorily, and it can be expected that the molding sand is compacted satisfactorily. Further, by retaining the captured image as data as necessary, a third party can determine the object from the image, and thus personal differences due to the inspection worker are less likely to occur.
As shown in fig. 3, the molding machine 50 includes a mold release agent tank 58 storing a mold release agent, and a mold release agent sprayer 60 (see a partially enlarged view) spraying the mold release agent stored in the mold release agent tank 58 into the flask 52. The mold release agent tank 58 and the mold release agent ejector 60 are members to be inspected which are set in advance in the molding machine 50. Therefore, a QR code (not shown) is attached to the periphery of the mold release agent tank 58, and a QR code (not shown) is also attached to the periphery of the mold release agent ejector 60.
Since the mold release agent tank 58 is a target member to be inspected, when the QR code attached to the mold release agent tank 58 is photographed, the amount of the mold release agent stored in the mold release agent tank 58 is displayed as an inspection item on the smartphone 20. Since the mold release agent ejector 60 is also a target member for inspection, when the QR code attached to the peripheral portion of the mold release agent ejector 60 is imaged, the smartphone 20 displays the clogging of the mold release agent ejector 60 and the leakage of liquid from the mold release agent ejector 60 as inspection items.
The amount of the release agent stored in the release agent tank 58 is confirmed by visually checking an inspection window (not shown) of the release agent tank 58. The inspection worker determines whether or not the amount of the release agent stored in the release agent tank 58 is equal to or more than a predetermined amount set in advance, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. Here, when the determination result that attention is required or an abnormality is input, the smartphone 20 displays a warning to image the inspection window of the release agent tank 58, and therefore the inspection worker performs imaging of the inspection window in accordance with the display of the smartphone 20. By checking and maintaining the amount of the release agent stored in the release agent tank 58, the release agent is favorably supplied from the release agent tank 58 into the flask 52, and thus a favorable release of the mold can be expected. Further, by retaining the captured image as data, a third party can determine the amount of the release agent from the image, and therefore, personal differences due to the inspection worker are less likely to occur.
Clogging of the release agent ejector 60 and leakage of liquid from the release agent ejector 60 were visually confirmed. The inspection worker determines whether the mold release agent ejector 60 is clogged or not and whether the liquid leaks from the mold release agent ejector 60 or not, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. Here, when the determination result that attention is required or an abnormality is input, the smartphone 20 displays a warning to take an image of the situation of clogging or liquid leakage, and therefore the inspection worker takes an image of the situation in accordance with the display of the smartphone 20. By checking and maintaining the blockage of the release agent ejector 60 and the leakage of the liquid from the release agent ejector 60, the release agent stored in the release agent tank 58 can be supplied into the sand box 52 well, and the mold can be expected to be released well. Further, by retaining the captured image as data, a third party can determine the state of clogging or liquid leakage from the image, and personal differences due to the inspection worker are less likely to occur.
The molding machine 50 further includes a gate pin 62 which is used for gate formation for forming a gate in the mold to be molded and which is extendable and retractable inside the flask 52. The gate pin 62 has a proximal end fixed to the compression plate 55 and a distal end configured to be retractable with the vertical direction of the apparatus as the axial direction. The gate is a first flow path for introducing the molten metal into the mold, and the gate is connected to the runner. The gate pin 62 is a member to be inspected in advance in the molding machine, and a QR code (not shown) is attached to the periphery of the gate pin 62.
Since the gate pin 62 is a component to be inspected, when the QR code attached to the periphery of the gate pin 62 is photographed, the movement of the gate pin 62 is displayed as an inspection item in the smartphone 20.
The movement of the gate pin 62 was confirmed by visual observation. The inspection worker determines whether or not the gate pin 62 is moving smoothly, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. By checking and maintaining the movement of the gate pin 62, it can be expected that an appropriate gate will be formed in the mold.
The molding machine 50 also includes a knockout pin 64 provided to the flask 52. The ejector pin 64 is attached to the opposing portions of the pair of flasks 52 (i.e., the lower end face of the upper flask 52 and the upper end face of the lower flask 52) so as to be capable of projecting and retracting, and is movable relative to the flasks 52 in the vertical direction of the apparatus by a cylinder (not shown) during operation. When the mold is released after the molding is completed, the match plate held by the flask 52 is pressed from above and below by the ejector pin 64, and a gap is formed between the flask 52 and the match plate that are strongly adhered to each other. After the gap is formed, the mold is opened by raising the upper flask 52 or lowering the lower flask 52. The flask 52 provided with the ejector pin 64 is a member to be inspected, and a QR code (not shown) is attached to the flask 52.
Since the flask 52 is a member to be inspected, when the QR code attached to the flask 52 is photographed, the movement of the knock-out pin 64 is displayed as an inspection item on the smartphone 20.
The movement of the ejector pin 64 is visually confirmed. The inspection worker determines whether the ejector pin 64 moves smoothly, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. By checking and maintaining the movement of the ejector pin 64, the ejector pin 64 works properly after molding, and thus a good mold release can be expected.
The molding machine 50 further includes an aeration tank unit 66 for filling a mold forming space formed inside the flask 52 with molding sand. An aeration nozzle 68 is formed at the lower end opening of the aeration tank portion 66. Further, a slide shutter 70 that opens and closes the upper end opening for sand injection in the aeration tank section 66 by sliding is provided in the upper end opening. Note that, although the detailed description is omitted, in the molding machine 50, a mechanism for moving the flask 52 is provided so that the sand blowing port of the side wall of the flask 52 is brought into contact with the aeration nozzle 68 to enable sand filling from the aeration nozzle 68 into the flask 52. The aeration tank unit 66 is a member to be inspected in the molding machine 50, and a QR code (not shown) is attached to the aeration tank unit 66.
Since the aeration tank unit 66 is a target member for inspection, when the QR code attached to the aeration tank unit 66 is photographed, the wear and the clogging of the aeration nozzle 68 and the wear of the slide shutter 70 are displayed as inspection items on the smartphone 20.
The wear and clogging of the aeration nozzle 68 were visually confirmed. The inspection worker determines whether or not the aeration nozzle 68 has exceeded the allowable limit of wear and clogging, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. Here, when the determination result that attention is required or an abnormality is input, the smartphone 20 displays a warning to take an image of the wear or the clogging, and therefore the inspection worker takes an image of the wear or the clogging in accordance with the display of the smartphone 20. In addition, the wear of the slide shutter 70 was also visually confirmed. The inspection worker determines whether or not the slide shutter 70 is worn beyond the allowable limit, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. Here, when the determination result that attention is required or an abnormality is input, the display prompting the smartphone 20 to capture the worn condition is completed, and therefore the inspection worker captures the condition in accordance with the display of the smartphone 20.
The sand inside the aeration tank portion 66 is satisfactorily filled into the mold molding space by checking and maintaining the wear and clogging of the aeration nozzle 68. Further, since the slide gate 70 works well by checking and maintaining the wear of the slide gate 70, a good supply of the molding sand into the interior of the aeration tank portion 66 can be expected.
When the inspections of all the inspection target components of the molding machine 50 are completed, the inspection worker connects the general-purpose terminal to the cloud and logs in the cloud, and transmits data of the inspection results to the cloud.
Here, although the frameless molding machine is described, the same inspection can be performed for the framed molding machine.
(inspection of pelletizer)
Next, a case where the device to be inspected is the pelletizer 76 will be described with reference to fig. 5. Fig. 5 shows a front view of the pelletizer 76. The granulator 76 is attached with a QR code (not shown).
Prior to the inspection of pelletizer 76, an inspection operator logs into cloud 34 from smartphone 20 as a general purpose terminal and downloads the required data. Further, prior to this, applications were downloaded from a network (e.g., apple, google, etc.) as needed. Next, the examination classification of whether daily examination or monthly examination is input to the smartphone 20. This enables the smartphone 20 to be used as an inspection terminal. Here, a case of a daily check will be described.
In the pelletizer 76, a pair of rollers 82 and a feed screw 80 are components of an inspection object. When the inspection worker photographs the QR code attached to the pelletizer 76 with the smartphone 20, the components to be inspected are listed on the smartphone 20. In addition, a QR code is attached to peripheral portions of the pair of rollers 82 and the feed screw 80.
That is, when the QR code attached to the peripheral portions of the pair of rollers 82 is photographed, the wear and the abnormal noise of the pair of rollers 82 and the pressure between the pair of rollers 82 are displayed as the inspection items in the smartphone 20. When the QR code attached to the peripheral portion of the feed screw 80 is photographed, the wear and the sound (abnormal sound) of the feed screw 80 are displayed as the inspection items on the smartphone 20.
Here, the pelletizer 76 will be described, and the pelletizer 76 shown in fig. 5 is a device for pressing and solidifying the supplied raw material to compact the raw material into a granulated substance (briquette). The pelletizer 76 includes a hopper 78, a feed screw 80 provided inside the hopper 78, and a pair of rollers 82 provided below the hopper 78.
The pair of rollers 82 are formed in a ring shape in cross section orthogonal to the rotation axes thereof, and are arranged in parallel in the horizontal direction so that the rotation axes are parallel to each other and are in close contact with each other. A plurality of concave grooves (not shown) are formed on the outer peripheral surfaces of the pair of rollers 82. The above-described concave grooves formed on the respective outer peripheral surfaces of the pair of rollers 82 are formed at positions on the respective outer peripheral surfaces that are fitted to each other in the circumferential direction.
The feed screw 80 provided inside the hopper 78 is provided with spiral fins (not shown) around its shaft (rotary shaft). A variable speed motor 86 for driving the feed screw 80 to rotate is connected to the shaft portion of the feed screw 80 via a driving force transmission mechanism 84. The feed screw 80 is rotated by the rotational drive force of the variable speed motor 86 to force the raw material in the hopper 78 between the pair of rollers 82.
On the other hand, a variable speed motor, not shown, for rotating the drive roller 82 is connected to shaft portions of the pair of rollers 82 via a drive force transmission mechanism, not shown. Further, the driving force of the variable speed motor is converted into two outputs in opposite rotational directions 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 thus press-solidify the raw materials fed therebetween to compress them into granules.
Since the pair of rollers 82 are inspection target members, when the QR code attached to the peripheral portions of the pair of rollers 82 is photographed, the wear and the abnormal noise of the pair of rollers 82 and the pressure between the pair of rollers 82 are displayed as inspection items in the smartphone 20. The wear and abnormal noise of the pair of rollers 82 are confirmed by audio-visual observation. The inspection worker determines the degree of wear and abnormal noise of the pair of rollers 82, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. When the determination result that attention is required or an abnormality is input, the smartphone 20 displays a warning to capture the wear condition, and therefore the inspection worker captures the wear condition in accordance with the display of the smartphone 20. When the determination result that attention is required or abnormality is input as to the sound (abnormal sound), the smartphone 20 displays a warning to record the abnormal sound, and therefore the inspection worker records the sound in accordance with the display of the smartphone 20. By retaining the recorded data, a third party can make a situation determination based on the recorded data, and thus personal differences due to the inspection worker are less likely to occur. The pressure between the pair of rollers 82 is confirmed by visually reading a pressure gauge (not shown). The inspection worker determines whether or not the pressure indicated value between the pair of rollers 82 is a pressure value assumed in advance, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion.
Since the feed screw 80 is a target member to be inspected, when the QR code attached to the peripheral portion of the feed screw 80 is photographed, the wear and the abnormal noise of the feed screw 80 are displayed as inspection items on the smartphone 20. The wear and abnormal sound of the feed screw 80 are confirmed by audio-visual observation. The inspection worker determines the degree of wear and abnormal noise of the feed screw 80, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. When the determination result that attention is required or an abnormality is input, the smartphone 20 displays a warning to capture the wear condition, and therefore the inspection worker captures the wear condition in accordance with the display of the smartphone 20. When the determination result that attention is required or abnormality is input as to the sound (abnormal sound), the smartphone 20 displays a warning to record the abnormal sound, and therefore the inspection worker records the sound in accordance with the display of the smartphone 20.
By checking and maintaining the wear and noise of the feed screw 80, a proper amount of the raw material in the hopper 78 can be pressed between the pair of rollers 82. Thus, a suitable amount of the raw material is used to form a granulated substance having a suitable shape. Further, by checking and maintaining the pressure set value between the pair of rollers 82 and the pressure indicated value between the pair of rollers 82, it can be expected that the density of the granulated substance can be favorably maintained.
When the granulator 76 has completed the inspection of all the inspection target components, the inspection worker connects the universal terminal to the cloud, logs in the cloud, and transmits data of the inspection result to the cloud.
(inspection of brush polishing apparatus)
Next, a case where the apparatus to be inspected is the brush polishing apparatus 90 will be described with reference to fig. 6 and 7. Fig. 6 shows a front view of the brush polishing apparatus 90, and fig. 7 shows a side view of the brush polishing apparatus 90.
Before the inspection of the brush polishing apparatus 90, an inspection worker logs in the cloud 34 from the smartphone 20 as a general-purpose terminal, and downloads necessary data. Further, prior to this, applications were downloaded from a network (e.g., apple, google, etc.) as needed. Next, the examination classification of whether daily examination or monthly examination is input to the smartphone 20. This enables the smartphone 20 to be used as an inspection terminal. Here, a case of a daily check will be described.
In the brush polishing apparatus 90, the drive motor 98, the brush 96, the coolant circulating section 100, and the mounting jig 94 are members to be inspected, and an inspection region or an inspection site. When the inspection worker photographs the QR code attached to the brush polishing apparatus 90 with the smartphone 20, the components to be inspected, the inspection area, or the inspection portion are displayed in a list on the smartphone 20.
As shown in fig. 7, the brush polishing apparatus 90 includes a revolving table 104 disposed in a range including the polishing chamber 102. The revolution table 104 is driven to rotate by a motor 106. Further, a plurality of (two in the present embodiment) rotating tables 108 arranged at equal intervals in the circumferential direction are arranged on the revolving table 104. The turntable 108 is driven to rotate by a driving force of a motor 110 when it is arranged at a predetermined position (a position below the brush 96 described later) in the polishing chamber 102.
The rotation table 108 is provided with a mounting jig 94 for mounting the object to be processed on the mounting unit 92. On the other hand, the brush 96 is provided at a height position above the revolving table 104 and the rotating table 108 in the polishing region of the polishing chamber 102. The brush 96 is disposed so that its bristle tips face downward, and is driven to rotate by a drive motor 98 shown in fig. 6 and 7. Thus, the brush 96 shown in fig. 7 grinds the surface of the object to be treated by rotating and contacting the object to be treated attached to the installation section 92 by the attachment jig 94. The brush polishing apparatus 90 includes a contact portion between the brush 96 and the object to be processed, a mechanism (not shown) for spraying a coolant to a peripheral portion thereof, and a coolant circulating portion 100 for circulating the coolant.
Since the drive motor 98 is a member to be inspected in the brush polishing apparatus 90, a QR code (not shown) is attached to a peripheral portion of the drive motor 98. When the QR code attached to the peripheral portion of the drive motor 98 is photographed, the current value, abnormal sound, and vibration of the drive motor 98 are displayed as inspection items in the smartphone 20.
The current value of the drive motor 98 was confirmed by visual observation with an ammeter, and abnormal noise and vibration of the drive motor 98 were confirmed by visual observation. The inspection worker determines whether or not the current value of the drive motor 98 is a current value assumed in advance and the degree of abnormal noise and vibration of the drive motor 98, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. When the determination result that attention is required or abnormality is input as to the sound (abnormal sound), the smartphone 20 displays a warning to record the abnormal sound, and therefore the inspection worker records the sound in accordance with the display of the smartphone 20.
Thus, the presence or absence of a failure in the basic function of the brush polishing apparatus 90 is previously confirmed. Here, the brush 96 shown in fig. 7 is rotated appropriately by checking and maintaining the current value, abnormal noise, and vibration of the drive motor 98, and it can be expected that the surface of the object to be processed is polished well by the brush 96. Further, since the third party can make a situation determination based on the recorded data by keeping the recorded data, it is not easy for the individual difference to occur due to the inspection worker.
Since the brush 96 shown in fig. 7 is a member to be inspected which is set in advance in the brush polishing apparatus 90, a QR code (not shown) is attached to a peripheral portion of the brush 96. When the QR code attached to the peripheral portion of the brush 96 is photographed, the wear of the brush 96 is displayed as an inspection item on the smartphone 20.
Wear of the brush 96 was confirmed by visual observation. The inspection worker determines the degree of wear of the brush 96 and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. When the determination result that attention is required or an abnormality is output as to the degree of wear, the smartphone 20 displays a warning to capture the state of wear, and therefore the inspection worker captures the state of wear in accordance with the display of the smartphone 20. By inspecting and maintaining the wear of the brush 96, it can be expected that the surface of the object to be processed is precisely polished by the brush 96. Further, by retaining the captured image as data, a third party can determine the degree of wear from the image, and thus personal differences due to the inspection worker are less likely to occur.
Since the coolant circulation unit 100 is also a member to be inspected in the brush polishing apparatus 90, a QR code (not shown) is attached to a peripheral portion of the coolant circulation unit 100. Then, when the QR code attached to the peripheral portion of the coolant circulation unit 100 is photographed, the circulation of the coolant is displayed as an inspection item on the smartphone 20.
The circulation of the coolant is confirmed by visually checking the operation state of the coolant circulation portion 100. The inspection worker 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 smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. When the determination result that the operation state is the attention-demanding or abnormal is input, the smartphone 20 displays the image of the operation state in a reminder manner, and therefore the inspection worker photographs the operation state in accordance with the display of the smartphone 20. By checking and maintaining the circulation of the coolant, the cooling by the coolant is satisfactorily completed when the object to be processed is ground by the brush 96. Further, by retaining the captured image as data, a third party can determine the circulation state of the coolant from the image, and thus personal differences due to the inspection worker are less likely to occur.
Since the mounting jig 94 is also a member to be inspected in the brush polishing apparatus 90, a QR code (not shown) is attached to a peripheral portion of the mounting jig 94. Then, when the QR code attached to the peripheral portion of the mounting jig 94 is photographed, the wear of the mounting jig 94 is displayed as an inspection item on the smartphone 20.
The wear of the mounting jig 94 was confirmed by visual observation. The inspection worker determines the degree of wear of the mounting jig 94, and inputs the determination result (inspection result) to the smartphone 20. The input to the smartphone 20 is classified into three categories, normal, attention-demanding, and abnormal, according to the determination criterion. When the determination result that the degree of wear is attention-demanding or abnormal is input, the smartphone 20 displays a warning to capture the state of wear, and therefore the inspection worker captures the state of wear in accordance with the display of the smartphone 20. Here, by checking and maintaining the wear of the mounting jig 94, it can be expected that the polishing is performed in a state where the object to be processed is appropriately mounted. Further, by retaining the captured image as data, a third party can determine the degree of wear from the image, and therefore personal differences due to the inspection worker are less likely to occur.
When the brush polishing apparatus 90 completes the inspection of all the inspection target components, the inspection area, or the inspection portion, the inspection worker connects the smartphone 20 to the cloud, logs in the cloud, and transmits data of the inspection result to the cloud.
Furthermore, here, one check is done for each device. That is, before starting an inspection for each device, an inspection worker logs in the cloud 34 from the smartphone 20 or the like, which is a general-purpose terminal, and downloads necessary data. Further, prior to this, applications were downloaded from a network (e.g., apple, google, etc.) as needed. Then, at the time when the inspection of all the inspection target components, the inspection area, or the inspection portion of the device is completed, the smartphone 20 is connected to the cloud and registered, and the data of the inspection result is transmitted to the cloud.
However, for example, when a plurality of devices exist in one site, a plurality of necessary data are downloaded from the cloud 34 in a unified manner. Further, prior to this, applications were downloaded from a network (e.g., apple, google, etc.) as needed. Further, the smartphone 20 may be connected to the cloud and logged in at the time when the inspection of the plurality of devices is completed, and data of the inspection result may be transmitted to the cloud. Further, in the case where there are a plurality of devices, data necessary for each device is downloaded from the cloud 34. Further, prior to this, applications were downloaded from a network (e.g., apple, google, etc.) as needed. Moreover, after the device is checked, the data of the checking result is sent to the cloud end, and then the next device can be checked.
