[0006] Technical Problem to be Solved by the Invention

[0007] Here, in recent years, in a forming device accompanied by heating or a forming device accompanied by fluid supply, unlike a forming device that only performs operations such as pressing, processes such as a heating step or a fluid supply step are added, making it complicated. Thus, as the processes become complicated, there is a demand for improving the quality of products and the production efficiency.

[0008] The present invention has been completed to solve such problems, and an object thereof is to provide a method for displaying the operating status of a forming device that can improve the quality of products produced by the forming device and the production efficiency.

[0009] Means for Solving the Technical Problem

[0010] A method for displaying the operating status of a forming device according to one aspect of the present invention is a display method for displaying the operating status of a forming device that forms a metal material by heating the metal material on a screen of a display device, wherein at least one of a first display unit, a second display unit, and a third display unit is used to display the operating status with a time axis starting from a time point X hours before the present time, the first display unit displays the operating status of the forming device within an arbitrarily set past X hours from the current time at an operating rate of 0 to 100%, the second display unit separately displays whether or not the formed product has changed, and the third display unit displays the cumulative quantity and the good product / bad product situation at each time t.

[0011] In the method for displaying the operating status of a forming device, by using at least one of the above-mentioned first display unit, second display unit, and third display unit, the operating status can be displayed on a timeline with a starting point at a time X hours ago. At this time, the operating status or operating rate of the forming device can be easily confirmed at any time, and information related to the operating status corresponding to the time can be easily grasped. Therefore, the product quality and production efficiency of the forming device can be improved.

[0012] It can be as follows: The display device can display a fourth display unit, and the fourth display unit uses products as the horizontal axis and displays a summary chart of the change status of the device operation data related to the forming quality during an arbitrarily set past X hours from the current time. At this time, the change situation of the forming quality in the forming device can be easily grasped.

[0013] The method for displaying the operating status of a forming device is a display method for displaying the operating status of a forming device through the screen of a display device of a management device installed in a management system for multiple forming devices. Among them, the display device can display an operating status image that displays the operating status of multiple forming devices together in a screen segmentation form according to the machine number, and the display device can also display a summary image that only displays the detailed operating status of the corresponding machine number by clicking on a specific position in the segmented screen of each machine number in the operating status image.

[0014] In the method for displaying the operating status of a forming device, the operating status of multiple forming devices can be grasped together through the operating status image. And the operating status of a specific forming device can be grasped through the summary image. Thus, multiple forming devices can be appropriately managed, and the product quality and production efficiency of the forming device can be appropriately improved.

[0015] It can be as follows: The display device displays a fifth display unit, and the fifth display unit displays an abnormal history record image by selecting from a menu screen independent of the first display unit, second display unit, and third display unit. At this time, in the fifth display unit, the abnormal history record of the forming device can be grasped.

[0016] It can be as follows: According to the change status of the device operation data related to the forming quality of the fourth display unit, at least one of the detection contents of heating abnormality and fluid seal leakage abnormality is detected, and thus a state abnormality is detected, and the detection content is displayed on the display device. At this time, the state abnormality can be quickly detected based on the device operation data that affects the forming quality and notified to the operator.

[0029] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, in each drawing, the same or corresponding parts are denoted by the same reference numerals, and redundant descriptions are omitted.

[0030] Figure 1 FIG. is a schematic structural diagram showing the structure of a production management system 100 that executes the method for displaying the operating status of the forming device according to the present embodiment. The production management system 100 is a system for performing production management of a forming device 10 that forms a metal material. As Figure 1 shown, the production management system 100 includes a forming device 10, a control device 101, and a display device 102. In the present embodiment, as the metal material, a metal tube material 5 is used.

[0031] The forming device 10 is a device for processing the heated metal tube material 5. In the present embodiment, the forming device 10 performs pressure forming on the heated metal tube material 5. In the present embodiment, as the forming device 10, a forming device is adopted which forms and quenches a hollow-shaped metal tube by supplying a fluid to the heated metal tube material 5 and bringing it into contact with the forming surface of the forming die. The forming device 10 is provided with a temperature sensor 50 and a pressure sensor 51.

[0032] Figure 2 is a schematic diagram showing the structure of the forming device 10. As Figure 2 shown, in the present embodiment, the forming device 10 is arranged on a horizontal plane. The forming device 10 includes a forming die 11, a holding portion 12, a fluid supply portion 13, and a heating portion 14. In addition, in this specification, the metal tube material 5 refers to a hollow object before the forming in the forming device 10. The metal tube material 5 is a tube material of a steel type capable of quenching. Sometimes the direction in which the reference axis of the metal tube material 5 extends when the metal tube material 5 is arranged in the forming device 10 is referred to as the "axial direction D1". And sometimes the direction orthogonal to the axial direction D1 in the horizontal direction is referred to as the "width direction D2".

[0033] The forming die 11 is a die for forming the metal tube material 5 into a metal tube, and includes a lower die 16 and an upper die 17 which are opposed to each other in the vertical direction. The lower die 16 and the upper die 17 are made of steel blocks. Recesses for accommodating the metal tube material 5 are respectively provided in the lower die 16 and the upper die 17. The lower die 16 and the upper die 17 form a space for the target shape of the metal tube material 5 to be formed by the respective recesses in a state where they are in close contact with each other (closed die state). Therefore, the surface of each recess becomes the forming surface of the forming die 11. The lower die 16 is fixed to the base 18 via a die holder or the like. The upper die 17 is fixed to the slider of the drive mechanism via a die holder or the like. In addition, the drive mechanism is a mechanism for moving at least one of the lower die 16 and the upper die 17. And a flow path for cooling water for cooling the dies 16 and 17 is formed in the dies 16 and 17.

[0034] The holding part 12 is a mechanism for holding the metal tube material 5 disposed between the lower die 16 and the upper die 17. The holding part 12 includes: a holding member 21A that holds the metal tube material 5 on one end side in the axial direction D1 of the forming die 11; and a holding member 21B that holds the metal tube material 5 on the other end side in the axial direction D1 of the forming die 11. The holding members 21A and 21B on both sides in the axial direction D1 are each divided into an upper side member and a lower side member, and hold the metal tube material 5 by clamping the vicinity of the end portion of the metal tube material 5 in the vertical direction. A drive mechanism (not shown) is provided in the holding members 21A and 21B, and they can move in the vertical direction. In addition, the holding members may not be divided into upper and lower sides, and for example, they may be divided into left and right sides.

[0035] The fluid supply part 13 is a mechanism for supplying high-pressure fluid into the metal tube material 5 held between the lower die 16 and the upper die 17. The fluid supply part 13 supplies high-pressure fluid to the metal tube material 5 in a high-temperature state to expand the metal tube material 5. The fluid supply part 13 is provided on both end sides in the axial direction D1 of the forming die 11. The fluid supply part 13 includes: nozzles 22A and 22B that supply fluid into the metal tube material 5 from the opening portions at the ends of the metal tube material 5 respectively; and drive mechanisms 23A and 23B that move the nozzles 22A and 22B forward and backward with respect to the opening portions of the metal tube material 5. In addition, the fluid supply part 13 may supply a gas such as high-pressure air or inert gas as the fluid. The fluid supply part 13 has a high-pressure gas generating device 52 for supplying high-pressure fluid to the nozzles 22A and 22B. The high-pressure gas generating device 52 supplies high-pressure fluid to the nozzles 22A and 22B. And the fluid supply part 13 may be the same device as the holding part 12 having a mechanism for moving the metal tube material 5 in the vertical direction.

[0036] The heating part 14 is a device for heating the metal tube material 5. The heating part 14 heats the metal tube material 5 by energizing the metal tube material 5. The heating part 14 uses the holding members 21A and 21B as electrodes. The heating part 14 allows current to flow from the power source 56 through the holding members 21A and 21B as electrodes to the metal tube material 5 in a state where the metal tube material 5 is held by the holding members 21A and 21B as electrodes.

[0037] The forming device 10 is provided with a temperature sensor 50 for detecting the temperature of the metal tube material 5. The temperature sensor 50 can be a type of sensor that detects temperature by contacting the metal tube material 5, such as a thermocouple. Alternatively, the temperature sensor 50 can be a type of sensor that detects temperature in a non-contact manner with the metal tube material 5 using infrared rays or radiant heat. The forming device 10 is provided with a pressure sensor 51 for detecting the fluid pressure applied to the metal tube material 5. The pressure sensor 51 is provided on the supply line from the high-pressure gas generating device 52 to the nozzles 22A and 22B.

[0038] As Figure 1 shown, the control device 101 includes, for example, a processor, a memory, a storage device, and a communication interface, and can be configured as a computer. The processor is an arithmetic unit such as a CPU (Central Processing Unit). The memory is a storage unit such as a ROM (Read Only Memory) or a RAM (Random Access Memory). The storage device is a storage unit (storage medium) such as an HDD (Hard Disk Drive). The communication interface is a communication device for realizing data communication. The processor controls the memory, the storage device, and the communication interface to realize the functions of the control device 101 described later. In the control device 101, for example, the program stored in the ROM is loaded into the RAM, and various functions are realized by the CPU executing the program loaded into the RAM. The control device 101 includes an input processing unit 111, an arithmetic processing unit 112, and a production management system server 113.

[0039] The input processing unit 111 is composed of an AD converter or the like, digitally converts the signals input from the sensors 50 and 51 of the forming device 10, and sends them to the arithmetic processing unit 112.

[0040] The arithmetic processing unit 112 creates quality management data for each formed product based on the information obtained from the input processing unit 111. The arithmetic processing unit 112 creates the temperature of each metal tube material 5 during the hot forming of the metal tube material 5 as a production management parameter. Also, the arithmetic processing unit 112 creates the fluid pressure of each during the forming of the metal tube material 5 using fluid as a production management parameter. The arithmetic processing unit 112 creates, for example, the maximum heating temperature during the heating period, the time required for heating, the maximum fluid pressure during the supply of high-pressure fluid, the input time, etc. as production management parameters. After the arithmetic processing unit 112 creates an ID for each formed product, associates the above production management parameters with the ID to create a file, and then sends it to the production management system server 113 using FTP or the like.

[0041] The display device 102 is a device that browses data by accessing the production management system server 113 and displays the browsing information to the user. The display device 102 is composed of a portable terminal such as a personal computer or a smartphone. The display device 102 can browse the data of the production management system server 113 by installing browsing software. Moreover, when the production management system server 113 detects abnormal data, it can notify the display device 102 of the abnormality.

[0042] Next, referring to Figure 3 and Figure 4 , an example of the image displayed on the display device 102 will be described. Figure 3 is an example of an image showing the production parameters of the molded products produced in the past. The display device 102 displays an image GF1 as shown in Figure 3 . The image GF1 has display areas E1 to E5.

[0043] The display area E1 is an area for inputting information for sorting the IDs of the molded products to be browsed. The user inputs the ID of the molded product to be the browsing object in the display area E1. The display area E2 is an area for selecting the display form when displaying the browsed information. In the display area E2, the display form can be selected from "table", "line graph", "bar graph", and "scatter graph". The user clicks on the desired display form to make a selection.

[0044] The display area E3 is an area for inputting information for sorting the target period of the molded products to be browsed. The user inputs the target period of the molded product to be the browsing object in the display area E3. The display area E4 is an area for selecting the items to be browsed among the production management parameters. Examples of the items include the actual current of the electric heating, the temperature reached by the electric heating, the material temperature at the end of the stroke, the electric heating time, the primary blow molding time, the secondary blow molding time, the elongation of the metal tube material 5 at the end of heating, the primary blow molding gas pressure (left), the primary blow molding gas pressure (right), the secondary blow molding gas pressure (left), and the secondary blow molding gas pressure (right). The user makes a selection by clicking on the item to be browsed in the display area E4.

[0045] The display area E5 is an area for displaying the production management parameters according to the information selected by the user in the display areas E1 to E4. In the example of Figure 3 , the table is selected as the display form, so the relevant production management parameters are displayed at the corresponding positions in the table for each molded product corresponding to the selected ID. Additionally, when the line graph is selected as the display form, a line graph with the horizontal axis set as the ID and the vertical axis set as the value of the production management parameter is displayed in the display area E5. At this time, the threshold value for abnormality determination can be displayed in the graph.

[0046] Figure 4 It is an image showing the production status of the molded products molded by the molding device 10 in one day on the selected date. The display device 102 displays an image GF2 as shown in Figure 4 The image GF2 has display areas E10 to E13. The display area E10 is an area showing the IDs of the molded products manufactured on the selected date. In Figure 4 , molded products with two IDs, "SAMPLE (sample)_0" and "SAMPLE_1", were manufactured. In "SAMPLE_0" and "SAMPLE_1", the metal tube material 5 to be molded changes, so the molds used in the molding device 10 also change. Thus, even when the mold changes, the production status can be displayed on the display device. The display area E10 corresponds to the "second display unit" that distinguishes and displays whether the molded product has changed.

[0047] The display area E11 is an area showing the operating status of the molding device 10 on the selected date in a pie chart. In the display area E11, the time ratio when the molding device 10 is "operating", the time ratio when it is "stopped", and the time ratio when "an abnormality has occurred" are shown. Thus, the ratio of the status can be displayed daily, and can also be displayed monthly and annually, so the production status of the equipment can be grasped. The display area E11 corresponds to the "first display unit" that displays the operating status of the molding device within an arbitrarily set past X hours from the current moment at an operating rate of 0 to 100%.

[0048] The display area E12 is an area showing the operating status of the molding device 10 on the selected date by time. In the display area E12, the time when the molding device 10 is "operating", the time when it is "stopped", and the time when "an abnormality has occurred" are shown. In Figure 4 the example shown, it can be confirmed that an abnormality occurred around 15:00. In the display area E12, the time when the power supply of the molding device 10 is turned off (OFF) is also displayed. In addition, in Figure 4 , the status on the day when the molding device 10 is operating is shown. Since the current time is around 17:00, data from 0:00 to the current time is shown in the display area E12.

[0049] When the forming device 10 is in an abnormal state, such as in the display areas E11 and E12, the production management system 100 displays the abnormal state on the display device 102. The production management system 100 detects the abnormal state by detecting at least one of the heating abnormality and the fluid seal leakage abnormality. And the production management system 100 displays the detection content on the display device 102. Specifically, if the part of "Abnormality occurring" is clicked in the display area E12, the system will transfer to the alarm history screen, where the content of the abnormal state can be confirmed.

[0050] The display area E13 is an area for displaying a graph showing the production status of the formed products for each time period. In the display area E13, the production quantities of the formed products corresponding to each ID for each time period are shown. And when the material to be formed changes, the production management system server 113 changes the display form on the display device 102. Here, since formed products with two types of IDs, "SAMPLE_0" and "SAMPLE_1", are manufactured, a graph showing the production quantities of the formed products of each ID in a distinguishable state is shown. Around 13:00, the metal tube material 5 (the mold of the forming device 10) to be formed changes. Therefore, around 13:00, graphs of both "SAMPLE_0" and "SAMPLE_1" are shown. In other time periods, only one of "SAMPLE_0" and "SAMPLE_1" is manufactured, so only the graph of one of them is shown.

[0051] The display area E14 is an area for showing the quantities of qualified products (OK) and unqualified products (NG) for each time period. Here, the quantities of qualified and unqualified products of the two formed products, "SAMPLE_0" and "SAMPLE_1", are shown. The display area E13 and the display area E14 correspond to the "third display part" that shows the cumulative quantity and the good / defective situation for each t. In addition, the expression of good / defective products is not particularly limited and can be expressed as "OK" or "NG".

[0052] Thus, the display device 102 can use at least one of the display areas E11 (the first display part), the display area E10 (the second display part), and the display areas E13 and E14 (the third display part) to display the operating status with a time axis starting from the moment X hours ago in the past.

[0053] Figure 5 It is to Figure 3 change the table of the display area E5 of the image GF2 shown into an image of a trend graph. The display device 102 displays as Figure 5The image GF3 shown. The image GF3 has display areas E1 to E4 and a display area E20. In the display area E20, a trend graph showing the change status of the device operation data related to the forming quality of each formed product is shown. The device operation data related to the forming quality is the temperature of the material after heating or the temperature of the material before forming, the position of the material before forming, the fluid pressure, the clamping force, etc. The temperature reached by energized heating is set on the vertical axis of the display area E20. "USL" in the graph is the allowable upper limit temperature, and "LSL" is the allowable lower limit temperature. The display area E20 corresponds to the "fourth display unit", and this "fourth display unit" uses the product as the horizontal axis and displays a summary graph of the change status of the device operation data related to the forming quality during an arbitrarily set past X hours from the current time.

[0054] Figure 6 is based on Figure 5 the trend graph shown to detect an abnormal image. The display device 102 displays an image GF4 as Figure 6 shown. The image GF4 has display areas E1 to E4, a display area E20, and a display area E21. In the display area E21, based on the change status of the device operation data related to the forming quality in the display area E20 (the fourth display unit), at least one of the detection contents of heating abnormality and fluid seal leakage abnormality is detected, and thus the detection content when a state abnormality is detected is displayed. In Figure 6 No. 22, the situation when the temperature reached by energized heating is lower than the lower limit temperature is shown.

[0055] Here, as Figure 7 shown, the production management system 100 can be a multi-device management system that manages multiple molding devices 10. The display device 102 is installed on the management device 200. The display device 102 can display the operation status of multiple molding devices 10. Here, four molding devices 10 on production lines A to D are shown, but the number is not particularly limited. At this time, the display device 102 can display an operation status image GF5 as Figure 8 shown. Figure 8 is an image showing the operation status of multiple molding devices 10. As Figure 8 shown, the display device 102 can display an operation status image GF5 that shows the operation status of multiple molding devices 10 together in a screen division form by machine number. The operation status image GF5 has: a display area E30A, representing the operation status of the molding device 10 on production line A; a display area E30B, representing the operation status of the molding device 10 on production line B; a display area E30C, representing the operation status of the molding device 10 on production line C; and a display area E30D, representing the operation status of the molding device 10 on production line D. However, the number of display areas E30 changes according to the number of production lines of the molding device 10.

[0056] The display device 102 can also display a summary image that shows in detail only the operating status of the corresponding machine number by clicking on a specific position in the divided screen of each machine number in the operating status image GF5. For example, by clicking on one of the display areas E30A, E30B, E30C, E30D of the operating status image GF5, the display device 102 displays a summary image of only the clicked production line (machine number). Figure 9 is an example of a summary image. The display device 102 displays a summary image GF6 as shown in Figure 9 The summary image GF6 has display areas E31 to E35. The name of the displayed production line is shown in the display area E31. In the display area E32, the overall status of the production line is shown by the lighting of the lights "In production", "Adjusting", "Mold changing", "System stopped". In the display area E33, the lighting status and description of the lights (A to E) indicating the device status of the display area E34 are shown. In the display area E34, the status lights of devices A to E and the presence status of the molded products are displayed in real time with the product number ID. In addition, there are no molded products at the positions where the numbers are not shown. In the display area E35, the presence status of the molded products of devices A to E (the same as the display area E34) is displayed in real time with the product number ID. In addition, the product number ID of the molded products and the completion time are shown in the bottom list.

[0057] Figure 10 is an image showing the abnormal history. The display device 102 displays as shown in Figure 10The image GF7 shown. The image GF7 has display areas E41 to E46. In the display area E41, the period of abnormal display is selected. Here, it is possible to select a period such as "Selected period: Enter the period to be displayed in year / month / day", "Today: Abnormalities that occurred today", "1 week: Abnormalities in the past 1 week from today", "1 month: Abnormalities in the past 1 month from today". In the display area E42, the type of abnormality to be displayed is shown. Here, it becomes "All (ALL): Display all abnormalities", "Minor failure: Only display minor failures (alarm-level failures where the equipment does not stop)", "Major failure: Only display major failures (failures where the equipment stops running)". In the display area E43, when a device is selected, only the abnormalities related to the selected device are displayed, and when not selected, the abnormalities related to all devices are displayed. The selection contents here are "Loading table", "Press", "Cooling table", "Electric heating device", "High-pressure gas generating device", etc. In the display area E44, only the entered alarm number is displayed, and if no alarm number is entered, all generated alarms are displayed. In the display area E45, selection buttons for display or output are shown. Here, if "Display" is selected, the contents selected in the display areas E41 to E44 are displayed in the display area E46. If "CSV output" is selected, the contents selected in the display areas E41 to E44 are not displayed in the display area E46 but a CSV file is output. Regarding "Details", if this button is pressed after an alarm displayed in the display area E46 is selected with the mouse, the detailed content of the alarm (what kind of abnormality? Countermeasures, etc.) is displayed. In the display area E46, by pressing the display button in the display area E45, the alarms generated according to the contents selected in the display areas E41 to E44 are displayed. The display area E46 corresponds to the "fifth display unit", and this "fifth display unit" displays the abnormality history image by selecting from a menu screen separately provided from the above-mentioned display area E11 (first display unit), display area E10 (second display unit), and display areas E13, E14 (third display unit).

[0058] Next, the effects of the production management system 100 according to the present embodiment will be described.

[0059] The operating condition display method of the forming device 10 according to this embodiment is a display method for displaying the operating condition of the forming device 10 that forms a metal material by heating the metal material on the screen of the display device 102. Among them, at least one of the first display unit, the second display unit, and the third display unit is used to display the operating condition with the time axis starting from the moment X hours ago in the past. The first display unit displays the operating condition of the forming device within the arbitrarily set past X hours from the current moment at an operating rate of 0 to 100%. The second display unit separately displays whether there is a change in the formed product. The third display unit displays the cumulative quantity and the good product / bad product situation according to the time t.

[0060] In the operating condition display method of the forming device 10, by using at least one of the above-mentioned first display unit, second display unit, and third display unit, the operating condition can be displayed with the time axis starting from the moment X hours ago in the past. At this time, the operating condition or operating rate of the forming device 10 can be easily confirmed at any time, and the information related to the operating condition corresponding to the moment can be easily grasped. Therefore, the quality and production efficiency of the products of the forming device 10 can be improved.

[0061] It can be as follows: The display device 102 can display a fourth display unit that displays a summary graph of the change situation of the device operation data related to the forming quality during the arbitrarily set past X hours with the product as the horizontal axis starting from the current moment. At this time, the change situation of the forming quality in the forming device 10 can be easily grasped.

[0062] The operating condition display method of the forming device 10 is a display method for displaying the operating condition of the forming device 10 through the screen of the display device 102 of the management device 200 installed in the multiple management systems for managing multiple forming devices 10.
