[0004] [Patent Document 1] JP 2015-083352 A Summary of the Invention [Problem to be solved by the invention]

[0005] In some cases, multiple molding machines are installed on a factory production line. Therefore, if screenshots taken from multiple molding machines are stored in the same external memory or uploaded together to a server, it is time-consuming to later identify which molding machine the screenshot was taken from.

[0010] An injection molding machine 10 according to the present invention will be described below with reference to the drawings. The injection molding machine 10 is a device that injects a measured amount of molding material into a mold to form an injection molded product (hereinafter referred to as "injection molding"). However, a specific example of the molding machine is not limited to the injection molding machine 10, and may be an electric die-casting machine that injects molten metal (molding material) into a mold to form a molded product.

[0011] [Configuration of injection molding machine 10]

[0012] Fig. 1 is a side view of an injection molding machine 10 according to this embodiment. Fig. 2 is a hardware block diagram of the injection molding machine 10. As shown in Figs. 1 and 2, the injection molding machine 10 mainly includes a mold clamping device 20, an injection device 30, and a control device 60.

[0013] The clamping device 20 opens, closes, and clamps the mold 21. Specifically, the clamping device 20 mainly includes a fixed die plate 23 that supports a fixed-side mold 22, and a movable die plate 25 that supports a movable-side mold 24. The fixed-side mold 22 and the movable-side mold 24 are supported so as to face each other in the left-right direction (horizontal direction) of the injection molding machine 10.

[0014] The movable die plate 25 moves left and right along the tie bars 27 by transmitting the driving force of the die opening / closing motor 28 through the toggle link mechanism 26. When the movable die plate 25 moves leftward, the fixed die 22 and the movable die 24 move away from each other. On the other hand, when the movable die plate 25 moves rightward, the fixed die 22 and the movable die 24 come into contact with each other, forming a cavity (internal space) inside the die 21. Then, when pressure is further applied in a direction that moves the movable die plate 25 rightward, the fixed die 22 and the movable die 24 are clamped.

[0015] The injection device 30 plasticizes, measures, and injects the molding material. The injection device 30 according to this embodiment is disposed apart from the mold clamping device 20 in the horizontal direction (to the right of the mold clamping device 20). The injection device 30 mainly includes a heating cylinder 31, a screw 32, a hopper 33, and a hopper block 34.

[0016] The heating cylinder 31 is a cylindrical member extending in the left-right direction of the injection molding machine 10. The heating cylinder 31 mainly includes a resin passage 35 and a nozzle 36. In addition, a band heater 39 for heating the heating cylinder 31 is attached to the outer circumferential surface of the heating cylinder 31.

[0017] The resin passage 35 is a cylindrical space extending in the axial direction (longitudinal direction) inside the heating cylinder 31. The resin passage 35 communicates with the outside of the heating cylinder 31 (the cavity of the mold 21) through a nozzle 36 provided at the tip (front end) of the heating cylinder 31. In other words, the resin passage 35 is a space extending from the nozzle 36 along the axial direction.

[0018] The screw 32 is a cylindrical member. A spiral groove is formed on the outer circumferential surface of the screw 32. The screw 32 is accommodated in the internal space of the heating cylinder 31 in a state in which the screw 32 can move in the left-right direction of the injection molding machine 10 (hereinafter, referred to as "advance and retreat") and can rotate. The screw 32 advances and retreats when a driving force of an injection motor 37 is transmitted thereto, and rotates when a driving force of a metering motor 38 is transmitted thereto.

[0019] More specifically, when the injection motor 37 is rotated forward, the screw 32 moves (advances) toward the tip end (i.e., the nozzle 36) of the heating cylinder 31. On the other hand, when the injection motor 37 is rotated backward, the screw 32 moves (retreats) toward the base end (i.e., the opposite side to the nozzle 36) of the heating cylinder 31.

[0020] Hereinafter, within the range that the tip position of the screw 32 can reach within the heating cylinder 31, the position closest to the nozzle 36 will be referred to as the "forward limit," and the position farthest from the nozzle 36 will be referred to as the "reverse limit." Additionally, the terms "forward rotation" and "reverse rotation" of the injection motor 37 do not specify an absolute rotation direction, but merely specify a relative relationship (i.e., forward rotation and reverse rotation are rotations in opposite directions).

[0021] The hopper 33 is a funnel-shaped member that stores the raw molding material. The hopper block 34 is a member that supports the heating cylinder 31 and the hopper 33. The hopper 33 communicates with a resin passage 35 through the hopper block 34 at a portion of the heating cylinder 31 closer to the base end than the tip end. The molding material stored in the hopper 33 is supplied to the resin passage 35 of the heating cylinder 31 through an opening provided at the lower end. The molding material used in this injection molding machine 10 is, for example, so-called "pellets" that are formed into a cylindrical shape.

[0022] In the injection device 30, the screw 32 moves backward while rotating by rotating the injection motor 37 in the reverse direction and rotating the metering motor 38. As a result, the pellets supplied through the hopper 33 are filled (metered) into the resin passage 35 ahead of the screw 32 while being plasticized. In addition, in the injection device 30, the injection motor 37 rotates forward to move the screw 32 forward. As a result, the plasticized resin ahead of the screw 32 is injected into the cavity of the mold 21 through the nozzle 36.

[0023] [Configuration of control device 60]

[0024] 2, the control device 60 includes a central processing unit (CPU) 61 which is a calculation means, a read only memory (ROM) 62 which stores various programs, and a random access memory (RAM) 63 which is a working area for the calculation means. The CPU 61 may read and execute the programs stored in the ROM 62 to realize each process described below.

[0025] However, the specific configuration of the control device 60 is not limited to this, and may be realized by hardware such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).

[0026] The control device 60 controls the overall operation of the injection molding machine 10. More specifically, the control device 60 controls the mold opening / closing motor 28, the injection motor 37, the metering motor 38, and the band heater 39 based on various signals output from a rotary encoder 64, a load cell 65 (pressure sensor), and a temperature sensor 66.

[0027] The mold opening / closing motor 28, the injection motor 37, and the metering motor 38 are servo motors that generate driving forces to open and close the mold 21, driving forces to move the screw 32 back and forth, and driving forces to rotate the screw 32, for example, under the control of a servo amplifier (not shown).

[0028] The rotary encoder 64 is a sensor that detects the speed and tip position of the screw 32. More specifically, the rotary encoder 64 outputs a pulse signal corresponding to the rotation of the injection motor 37 to the control device 60. Then, the control device 60 specifies the speed of the screw 32 based on the number of pulse signals output per unit time. The control device 60 also specifies the tip position of the screw 32 based on the accumulated value of the pulse signals.

[0029] The load cell 65 is a sensor that detects the pressure applied to the screw 32. More specifically, the load cell 65 outputs a pressure signal (voltage value) corresponding to the pressure applied to the screw 32 to the control device 60. Then, the control device 60 identifies the pressure applied to the screw 32 based on the pressure signal output from the load cell 65.

[0030] The temperature sensor 66 detects the temperature of the heating cylinder 31, and outputs a temperature signal indicating the detected temperature to the control device 60. Then, the control device 60 determines the temperature of the heating cylinder 31 based on the temperature signal output from the temperature sensor 66.

[0031] A display input device 67 is also connected to the control device 60. The display input device 67 is a user interface that includes a display (display device) that displays various information to be notified to the operator, and buttons, switches, dials, and the like (input devices) that accept input operations by the operator. The display input device 67 may also include a touch panel superimposed on the display. The display input device 67 accepts input operations by the operator, and outputs an input signal corresponding to the accepted input operation to the control device 60.

[0032] Furthermore, an external storage device 68 is detachably connected to the control device 60. The external storage device 68 is an example of an external memory that stores screen shot image data, which will be described later. The external storage device 68 is preferably a portable and detachable device, such as a USB (Universal Serial Bus) memory or a memory card, for example, that is detachable from the injection molding machine 10.

[0033] The control device 60 repeatedly acquires at predetermined time intervals the signals output from the rotary encoder 64, the load cell 65, and the temperature sensor 66. The rotary encoder 64, the load cell 65, and the temperature sensor 66 are examples of sensors that measure physical quantities (e.g., position, speed, pressure, time, etc.) of the injection molding machine 10. That is, the control device 60 repeatedly acquires the physical quantities measured by the sensors at predetermined time intervals.

[0034] The control device 60 also acquires alarm information from each part of the injection molding machine 10. The alarm information is information indicating changes in the injection molding machine 10. More specifically, the alarm information is information indicating malfunctions, errors, and changes in status that have occurred in each part of the injection molding machine 10. The control device 60 then stores an alarm record including the alarm information and the acquisition time of the alarm information in the RAM 63. The alarm record is an example of history information indicating changes in the injection molding machine 10.

[0035] The alarm information is classified into, for example, a first type "CAUTION" and a second type "WARNING". The alarm information classified into the first type "CAUTION" is, for example, information indicating a change in the injection molding machine 10 that requires notification to an operator or confirmation by the operator but does not require the injection molding machine 10 to be stopped immediately. The alarm information classified into the second type "WARNING" is, for example, information indicating a change in the injection molding machine 10 that is so important that it requires the injection molding machine 10 to be stopped immediately.

[0036] That is, alarm information of higher importance than the first type "CAUTION" is classified into the second type "WARNING". However, the meanings of the first type "CAUTION" and the second type "WARNING" are not limited to the above examples. Moreover, the classification of alarm information is not limited to two types.

[0037] Furthermore, the control device 60 accepts an input operation by the operator to set molding conditions of the injection molding machine 10 through the display input device 67. The molding conditions refer to the operating conditions of injection molding by the injection molding machine 10. The molding conditions include setting items such as the injection speed, injection pressure, heater upper limit temperature, heater lower limit temperature, injection start position, mold opening / closing position, and rotation speed. The control device 60 then executes injection molding by operating the injection molding machine 10 according to the molding conditions input by the operator. The control device 60 also accepts an input operation by the operator to change the molding conditions through the display input device 67.

[0038] Fig. 3 shows an example of data of a set value record. When at least a part of the molding conditions is changed through the display input device 67, the control device 60 stores in the RAM 63 a set value record including the time when the molding conditions were changed, the changed setting item, the setting value before the change, and the setting value after the change, as shown in Fig. 3. The set value record is another example of history information showing changes in the injection molding machine 10.

[0039] [Notification processing]

[0040] Fig. 4 is a display example of an alarm history screen. Fig. 5 is a display example of a setting history screen. The control device 60 displays the alarm history screen shown in Fig. 4 or the setting history screen shown in Fig. 5 on the display input device 67 in accordance with an input operation by an operator to the display input device 67. The alarm history screen and the setting history screen are examples of status notification screens that notify the status of the injection molding machine 10.

[0041] 4 and 5, the alarm history screen and the setting history screen are common in that they include, for example, a title area A1, a status area A2, a measurement value area A3, a history area A4, and an icon area A5. That is, although the information displayed on the alarm history screen and the setting history screen differ, the overall layout is common.

[0042] The title area A1 is the area located at the top of the status notification screen. The status area A2 is the area located below the title area A1 and above the measurement value area A3 on the status notification screen. The measurement value area A3 is the area located below the status area A2 and above the history area A4 on the status notification screen. The history area A4 is the area located below the measurement value area A3 and above the icon area A5 on the status notification screen. The icon area A5 is the area located at the bottom of the status notification screen.

[0043] The title area A1 is an area for displaying the name of the screen. The status area A2 is an area for displaying important information to be notified to the operator (for example, alarm information classified as the second type "WARNING"). For example, as shown in FIG. 4, when the latest alarm information displayed in chronological order in the history area A4 is of the second type "WARNING", the control device 60 displays the alarm information in the status area A2. On the other hand, as shown in FIG. 5, when there is no important information to be notified to the operator, nothing is displayed in the status area A2.

[0044] The measurement value area A3 is an area that displays the physical quantities measured by the rotary encoder 64, the load cell 65, and the temperature sensor 66. The physical quantities displayed in the measurement value area A3 are not particularly limited, but in this embodiment, the screw position, injection speed, injection pressure, rotation speed, mold opening / closing position, and cycle timer are displayed. The control device 60 displays the latest physical quantities acquired from the rotary encoder 64, the load cell 65, and the temperature sensor 66 in the measurement value area A3. In other words, the control device 60 updates the display contents of the measurement value area A3 every time it acquires signals from the rotary encoder 64, the load cell 65, and the temperature sensor 66.

[0045] The history area A4 is an area in which multiple pieces of history information are displayed in chronological order. The control device 60 displays multiple pieces of history information stored in the RAM 63 in chronological order in the history area A4. That is, the control device 60 displays multiple alarm records in chronological order in the history area A4 of the alarm history screen shown in Fig. 4. The control device 60 also displays multiple setting value records in chronological order in the history area A4 of the setting history screen shown in Fig. 5.

[0046] The control device 60 displays multiple pieces of information contained in the history information in a single row, arranged horizontally. The control device 60 also displays multiple pieces of history information arranged vertically. More specifically, the control device 60 displays multiple pieces of history information arranged in reverse chronological order from top to bottom in the history area A4. That is, the history information displayed at the top of the history area A4 is the newest, and the history information displayed further down in the history area A4 is older.

[0047] Furthermore, when a large number of pieces of history information are stored in the RAM 63 as shown in Fig. 3, the control device 60 displays only a portion of the multiple pieces of history information in the history area A4 as shown in Fig. 5, and also displays a scroll bar SB at the right end of the history area A4. Then, the control device 60 slides the portion of the multiple pieces of history information shown in Fig. 3 to be displayed in the history area A4 in accordance with the operation of the scroll bar SB via the display input device 67. That is, the more the scroll bar SB is moved downward, the older the history information is displayed, and the more the scroll bar SB is moved upward, the newer the history information is displayed.

[0048] The icon area A5 is an area that displays icons that are operated by the operator through the display input device 67. In the icon area A5 according to this embodiment, a [single] icon and a [multiple] icon are displayed. The [single] icon and the [multiple] icon are icons for instructing the acquisition of a screenshot of the status notification screen. The [single] icon is an icon for acquiring only one screenshot of the status notification screen currently displayed on the display input device 67. On the other hand, the [multiple] icon is an icon for acquiring multiple screenshots by sliding the history area A4 of the status notification screen displayed on the display input device 67 so as to include all history information.

[0049] On the other hand, the alarm history screen and the setting history screen displayed on the display input device 67 do not include the machine number. The machine number is identification information that uniquely identifies the injection molding machine 10. The machine number is stored in advance in, for example, the ROM 62 or the RAM 63. Note that "uniquely identifying" is not limited to something that uniquely identifies all injection molding machines 10 manufactured by the manufacturer (for example, a serial number), but may also be something arbitrarily assigned by an administrator to uniquely identify the injection molding machine 10 within the factory (for example, a management number).

[0050] [Screenshot processing]

[0051] Fig. 6 is a flowchart of the screenshot process. Fig. 7 is a screenshot image of the alarm history screen of Fig. 4. Fig. 8 is a screenshot image of the setting history screen of Fig. 5 when the scroll bar SB is at the top. Fig. 9 is a screenshot image of the setting history screen of Fig. 5 when the scroll bar SB is at the center. Fig. 10 is a screenshot image of the setting history screen of Fig. 5 when the scroll bar SB is at the bottom.

[0052] The control device 60 executes the screenshot process shown in Fig. 6 in response to tapping on the [Single] icon or the [Multiple] icon in Fig. 4 or 5. Tapping on the [Single] icon or the [Multiple] icon is an example of an input operation that instructs taking a screenshot of the status notification screen.

[0053] First, the control device 60 judges whether or not the second type of history information is displayed in the status area A2 of the status notification screen currently displayed on the display input device 67 (S11). When the control device 60 judges that the second type of alarm information "WARNING" is displayed in the status area A2 (S11: Yes), as shown in Fig. 4, for example, the control device 60 deletes the alarm information from the status area A2 and changes the display mode of the corresponding alarm information in the history area A4 (S12), as shown in Fig. 7. On the other hand, when the control device 60 judges that the history information is not displayed in the status area A2 (S11: No), as shown in Fig. 5, for example, the control device 60 skips the process of step S12.

[0054] As shown in Fig. 7, among the history information included in the history area A4, making the history information deleted from the status area A2 bold is one example of making the display mode different from other history information. However, the method of making the display mode different is not limited to the example in Fig. 7, and the color may be changed, the text color and background color may be inverted (highlighted), or the display may be enclosed in a frame.

[0055] Next, the control device 60 superimposes the machine number "12345" registered in advance in the ROM 62 or RAM 63 onto the status area A2 of the status notification screen currently displayed on the display input device 67 as shown in Fig. 7 or 8 (S13). That is, the control device 60 replaces the alarm information displayed in the status area A2 with the machine number as shown in Fig. 4 and Fig. 7. Next, the control device 60 generates a screenshot image of the status notification screen with the machine number superimposed onto the status area A2 (S14).

[0056] Then, the control device 60 stores screenshot image data indicating the generated screenshot image in the external storage device 68. Alternatively, instead of storing the generated screenshot image data in the external storage device 68, the control device 60 may upload the generated screenshot image data to an external server via a communication network.

[0057] Next, the control device 60 judges whether the [Single] icon or the [Multiple] icon has been tapped (S15). As an example, when the control device 60 judges that the [Single] icon on the alarm history screen of Fig. 4 has been tapped (S15: No), the control device 60 generates only one screenshot image shown in Fig. 7 (S14) and ends the screenshot processing. As another example, when the control device 60 judges that the [Multiple] icon on the setting history screen of Fig. 5 has been tapped (S15: Yes), the control device 60 generates the screenshot image shown in Fig. 8 (S14) and then continues to execute the processing of step S16.

[0058] The control device 60 judges whether the scroll bar SB has reached the bottom end of the history area A4 (in other words, whether all the history information has been included in the screen shot image) (S16). If the control device 60 judges that the scroll bar SB has not reached the bottom end of the history area A4 (S16: No), the control device 60 slides the scroll bar SB of the setting history screen in Fig. 5 downward by a predetermined slide amount (i.e., shifts the portion of the multiple pieces of history information arranged in chronological order to be included in the history area A4) (S17).

[0059] Next, the control device 60 generates a screenshot image of the setting history screen by sliding the scroll bar SB downward by a predetermined amount (S14), as shown in Fig. 9. Then, the control device 60 repeatedly executes the processes of steps S14 to S17 until the scroll bar SB reaches the bottom end of the history area A4. That is, the control device 60 repeatedly generates screenshot images while shifting the portion of the multiple pieces of history information arranged in chronological order to be included in the history area.

[0060] In the examples of Figures 3 and 5, three screenshot images shown in Figures 8 to 10 are generated. The screenshot images shown in Figures 8 to 10 have the same display contents in the title area A1, status area A2, measurement value area A3, and icon area A5, but differ in the display contents in the history area A4. When the control device 60 determines that the scroll bar SB has reached the bottom end of the history area A4 (S16: Yes), it ends the screenshot processing.

[0061] Here, the amount of sliding of the scroll bar in step S17 may be, for example, an amount that allows a part of the history information to be included in an overlapping manner in the history area A4 of screenshot images generated adjacently in time. For example, when all the setting value records shown in Fig. 3 are included in the screenshot images, the first screenshot image (Fig. 8) includes the setting value records in the range R1, the second screenshot image (Fig. 9) includes the setting value records in the range R2, and the third screenshot image (Fig. 10) includes the setting value records in the range R3. In this example, the setting value records at the bottom of Fig. 8 and at the top of Fig. 9 overlap, and the setting value records at the bottom of Fig. 9 and at the top of Fig. 10 overlap.

[0062] [Effects of the embodiment] According to the above embodiment, by including the machine number in the screenshot image on the status notification screen, it becomes easy to later identify which injection molding machine 10 the screenshot image was acquired from.

[0063] Furthermore, according to the above embodiment, by combining the machine number above the measurement value area A3 and the history area A4, it becomes easier to identify the injection molding machine 10 that generated the screenshot image. However, the position where the machine number is combined is not limited to the examples of Figs. 7 to 10. Furthermore, the layout of the status notification screen and the information included in the status notification screen are not limited to the examples of Figs. 4 and 5. Furthermore, the control device 60 may delete the icon area A5 from the status notification screen to generate a screenshot image.

[0064] Furthermore, according to the above embodiment, by replacing the history information in the status area A2 with the machine number, the machine number is always synthesized at the same position, making it easier to identify the injection molding machine 10 that generated the screenshot image. However, the machine number may be synthesized at another position while leaving the history information in the status area A2.

[0065] Furthermore, according to the above embodiment, by making the display mode of the history information deleted from the status area A2 among the history information displayed in the history area A4 different from that of the other history information, it is possible to appropriately notify the status of the injection molding machine 10 on the screenshot image. However, the display mode of all the history information included in the history area A4 may be unified.

[0066] Furthermore, according to the above embodiment, by generating multiple screenshot images while shifting the scroll bar SB, a large amount of history information can be included in the screenshot images. This allows the state of the injection molding machine 10 to be checked and analyzed retroactively. Note that the scroll bar SB does not have to be included in the screenshot images. Also, the processes of steps S15-S17 can be omitted.

[0067] Furthermore, according to the above embodiment, by including history information in multiple screenshot images in a redundant manner, it becomes easy to identify the time sequence of multiple screenshot images after the fact. However, the number of pieces of history information included in the history area A4 of screenshot images generated adjacent in time is not limited to one, and may be two or more. Also, it is not necessary to include history information in the history area A4 of screenshot images generated adjacent in time.

[0068] The above-described embodiments are illustrative examples of the present invention, and are not intended to limit the scope of the present invention to these embodiments. Those skilled in the art can implement the present invention in various other forms without departing from the gist of the present invention. [Explanation of symbols]
