[0022] Hereinafter, an injection molding machine 10 according to the present invention will be described based on the accompanying drawings. The injection molding machine 10 is a device that injects a measured molding material into a mold and molds an injection molded product (hereinafter referred to as "injection molding"). However, a specific example of a molding machine is not limited to the injection molding machine 10, and may also be an electric die casting machine that injects molten metal (molding material) into a mold and molds a molded product.

[0023] [Structure of Injection Molding Machine 10]

[0024] Figure 1 It is a side view of the injection molding machine 10 according to the present embodiment. Figure 2 is a hardware block diagram of the injection molding machine 10. Figure 1 and Figure 2 As shown, the injection molding machine 10 mainly includes a mold clamping device 20 , an injection device 30 and a control device 60 .

[0025] The mold clamping device 20 performs opening, closing and mold clamping of the mold 21. Specifically, the mold clamping device 20 mainly includes a fixed mold plate 23 supporting the fixed side mold 22 and a movable mold plate 25 supporting the movable side mold 24. The fixed side mold 22 and the movable side mold 24 are supported to face each other in the left-right direction (horizontal direction) of the injection molding machine 10.

[0026] The driving force of the mold opening and closing motor 28 is transmitted through the toggle mechanism 26, whereby the movable die plate 25 moves in the left-right direction along the connecting rod 27. When the movable die plate 25 moves to the left, the fixed side mold 22 and the movable side mold 24 are separated. On the other hand, when the movable die plate 25 moves to the right, the fixed side mold 22 and the movable side mold 24 abut against each other, and a cavity (internal space) is formed inside the mold 21. And, if pressure is further applied in a direction to move the movable die plate 25 to the right, the fixed side mold 22 and the movable side mold 24 are molded together.

[0027] The injection device 30 plasticizes, measures, and injects the molding material. The injection device 30 of this embodiment is separated 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.

[0028] 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. A band heater for heating the heating cylinder 31 is attached to the outer peripheral surface of the heating cylinder 31.

[0029] The resin passage 35 is a cylindrical space extending in the axial direction (length direction) inside the heating cylinder 31. The resin passage 35 is connected to the outside of the heating cylinder 31 (the cavity of the mold 21) through the nozzle 36 provided at the top end (front end) of the heating cylinder 31. In other words, the resin passage 35 is a space extending from the nozzle 36 in the axial direction.

[0030] The screw 32 is a cylindrical component. A spiral groove is formed on the outer peripheral surface of the screw 32. The screw 32 is accommodated in the internal space of the heating cylinder 31 in a state of being movable in the left-right direction of the injection molding machine 10 (hereinafter referred to as "advance and retreat") and rotating. The screw 32 advances and retreats by transmitting the driving force of the injection motor 37, and rotates by transmitting the driving force of the metering motor 38.

[0031] In more detail, if the injection motor 37 is rotated in the forward direction, the screw 32 moves (advances) toward the top end of the heating cylinder 31 (i.e., the nozzle 36). On the other hand, if the injection motor 37 is rotated in the reverse direction, the screw 32 moves (retres) toward the base end of the heating cylinder 31 (i.e., the side opposite to the nozzle 36). Hereinafter, in the range that the top end position of the screw 32 in the heating cylinder 31 can reach, the position closest to the nozzle 36 is recorded as the "forward limit", and the position farthest from the nozzle 36 is recorded as the "retreat limit". In addition, the terms "forward rotation" and "reverse rotation" of the injection motor 37 do not determine the absolute rotation direction, but only determine the relative relationship (i.e., forward rotation and reverse rotation are rotations in opposite directions).

[0032] The hopper 33 is a funnel-shaped member that stores molding material as a raw material. The hopper block 34 is a member that supports the heating cylinder 31 and the hopper 33. The hopper 33 is connected to the resin passage 35 at a position closer to the base end than the top end of the heating cylinder 31 through the hopper block 34. 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 the injection molding machine 10 is, for example, so-called "pellets" molded into a cylindrical shape.

[0033] The injection device 30 rotates the injection motor 37 in the reverse direction and rotates the metering motor 38, thereby rotating the screw 32 while retreating. As a result, the pellets supplied from the hopper 33 are plasticized while being filled (metered) into the resin passage 35 in front of the screw 32. In addition, the injection device 30 rotates the injection motor 37 in the forward direction, thereby advancing the screw 32. As a result, the plasticized resin in front of the screw 32 is injected into the cavity of the mold 21 through the nozzle 36.

[0034] [Configuration of the Control Device 60]

[0035] like Figure 2As shown in FIG. 1 , the control device 60 includes a CPU (Central Processing Unit) 61 as a computing unit, a ROM (Read Only Memory) 62 storing various programs, and a RAM (Random Access Memory) 63 as a work area of ​​the computing unit. In addition, the CPU 61 can read out the program stored in the ROM 62 and execute it to realize each of the processes described below.

[0036] However, the specific structure of the control device 60 is not limited thereto, and may be realized by hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array).

[0037] The control device 60 controls the overall operation of the injection molding machine 10. More specifically, the control device 60 controls the mold opening and closing motor 28, the injection motor 37, and the metering motor 38 based on various signals output from the rotary encoder 64 and the load cell 65 (pressure sensor).

[0038] The mold opening and closing motor 28 , the injection motor 37 , and the metering motor 38 are servomotors that generate driving force for opening and closing the mold 21 , for advancing and retreating the screw 32 , and for rotating the screw 32 under control of, for example, a servo amplifier (not shown).

[0039] 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 determines the speed of the screw 32 based on the number of pulse signals output per unit time. In addition, the control device 60 determines the tip position of the screw 32 based on the accumulated value of the pulse signal.

[0040] 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 determines the pressure applied to the screw 32 based on the pressure signal output from the load cell 65.

[0041] In addition, an external storage device 66 is connected to the control device 60. The external storage device 66 is capable of storing a plurality of condition data (see Figure 3) is an example of a memory. As the external storage device 66, for example, a HDD (Hard Disk Drive), a USB (Universal Serial Bus) memory, etc. can be used. However, the memory may also be a RAM 63 mounted on the control device 60. Figure 3 Describes the details of the condition data.

[0042] In addition, a display input device 67 is connected to the control device 60. The display input device 67 is a user interface including a display (display device) that displays various information to be reported to the operator and buttons, switches, dials, etc. (input device) that receive input operations from the operator. In addition, the display input device 67 may also include a touch panel overlapped with the display. The display input device 67 receives input operations from the operator and outputs an input signal corresponding to the received input operations to the control device 60.

[0043] [Example of condition data]

[0044] Figure 3 is an example of a plurality of condition data stored in the external storage device 66. Figure 3 As shown, the external storage device 66 can store a plurality of condition data. The condition data is data indicating the operation conditions (hereinafter referred to as "molding conditions") of the injection molding of the injection molding machine 10. The condition data is, for example, binary data or text data in which a plurality of setting values ​​are arranged in a predetermined order.

[0045] The condition data involved in this embodiment includes, for example, a condition data name, a manufacturing date, and a plurality of setting values ​​(position, injection speed, primary pressure, holding pressure, timing, holding pressure speed). In addition, the setting values ​​included in the condition data are not limited to the above examples. Furthermore, the condition data may include not only setting values ​​indicating the operation of the injection device 30, but also setting values ​​indicating the operation of the mold clamping device 20.

[0046] The condition data name is an identifier for uniquely identifying a plurality of condition data stored in the external storage device 66. The condition data name can be arbitrarily set by the operator through the display input device 67, for example. The creation date is the date on which the condition data was created. In addition, when the condition data is updated through the selection condition preview screen described later, the updated date can also be set as the creation date.

[0047] The setting value "position" indicates the position (mm) of the top end of the screw 32 in the heating cylinder 31. More specifically, the setting value "position" indicates the switching position of the speed of the screw 32 when injecting the plasticized resin (hereinafter referred to as the "injection process"). In addition, the setting value "position" can include a plurality of switching positions. In addition, the position in the heating cylinder 31 can be expressed as the distance from the forward limit toward the base end of the heating cylinder 31 when the forward limit is set to 0 mm. The position of the top end of the screw 32 is detected by the rotary encoder 64.

[0048] The setting value "injection speed" indicates the forward speed (mm / s) of the screw 32 in the injection process. More specifically, the setting value "injection speed" can include a plurality of speeds switched at a plurality of switching positions indicated by the setting value "position". That is, the forward speed indicated by the setting value "injection speed" is the forward speed of the screw 32 between adjacent switching positions. The forward speed of the screw 32 is detected by the rotary encoder 64.

[0049] The set value "primary pressure" indicates the maximum value (MPa) of the pressure applied to the screw 32 during the injection process. That is, in the injection process, the speed control based on the set value "injection speed" is prioritized, but when the pressure indicated by the set value "primary pressure" is reached, the pressure control is performed in a manner not to exceed the pressure. The pressure applied to the screw 32 is detected by the load cell 65.

[0050] That is, if according to Figure 7 According to the selected condition data shown in FIG. 1 , the control device 60 advances the screw 32 at 10 (mm / s) between 32.00 (mm) and 30.00 (mm), at 25 (mm / s) between 30.00 (mm) and 25.00 (mm), at 40 (mm / s) between 25.00 (mm) and 10.00 (mm), at 30 (mm / s) between 10.00 (mm) and 5.00 (mm), and at 10 (mm / s) after 5.00 (mm). In addition, in the injection process, the control device 60 performs speed control within a range not exceeding the maximum value (=50 (MPa)) of the pressure applied to the screw 32 so that the injection speed approaches the set value.

[0051] The setting value "holding pressure" indicates the pressure (MPa) applied by the screw 32 to the plasticized resin injected into the mold 21. In other words, the setting value "holding pressure" indicates the pressure applied by the screw 32 in the forward direction after the injection of the plasticized resin is completed (hereinafter, this process is referred to as "holding pressure process"). The setting value "holding pressure" can include multiple pressures. The pressure applied by the screw 32 is detected by the force sensor 65.

[0052] The setting value "timing" indicates the switching timing (sec) of multiple pressures indicated by the setting value "pressure holding". The setting value "timing" indicates the elapsed time from the end of the injection process (start of the pressure holding process). The setting value "timing" can include multiple switching timings. The elapsed time is measured by the system clock mounted on the control device 60.

[0053] The set value "pressure holding speed" indicates the maximum value (mm / s) of the speed of the screw 32 in the pressure holding process. That is, in the pressure holding process, pressure control based on the set value "pressure holding" is prioritized, but when the speed indicated by the set value "pressure holding speed" is reached, speed control is performed so as not to exceed the speed. The forward speed of the screw 32 is detected by the rotary encoder 64.

[0054] That is, if according to Figure 7 According to the selected condition data shown in the figure, the control device 60 applies 10.0 (MPa) to the plasticized resin in the mold 21 for 0.50 (sec) from the start of the pressure holding process, applies 20.0 (MPa) for the next 0.50 (sec), applies 15.0 (MPa) for the next 0.50 (sec), and applies 10.0 (MPa) for the next 0.50 (sec). In addition, in the pressure holding process, the control device 60 controls the pressure so that the pressure is close to the set value within the range not exceeding the maximum value (=10 (mm / s)) of the forward speed of the screw 32.

[0055] One of the plurality of condition data stored in the external storage device 66 is "selection condition data" selected in advance by the display input device 67. On the other hand, among the condition data stored in the external storage device 66, condition data different from the selection condition data is "standby condition data". That is, the external storage device 66 contains only one selection condition data and one or more (in the present embodiment, a plurality of) standby condition data. In the present embodiment, the condition data C identified by the condition data name "data C" is set as "selection condition data", and the condition data A and B identified by the condition data names "data A" and "data B" are set as "standby condition data".

[0056] The control device 60 controls the mold clamping device 20 and the injection device 30 according to the selected condition data, thereby causing the injection molding machine 10 to perform injection molding. That is, by selecting different condition data, the action of the injection molding machine 10 during injection molding (in other words, the quality of the injection molded product) may be different. On the other hand, the standby condition data is condition data that is not used for injection molding at the current time point. However, by switching operations via the display input device 67, the selected condition data and the standby condition data can be switched (that is, one of the standby condition data is set as a new selected condition data).

[0057] For example, the operator of the injection molding machine 10 changes a part of the setting value included in the condition data A to create condition data B based on the result of injection molding using the condition data A (at this point in time, the condition data A becomes the selected condition data). Next, based on the result of injection molding using the condition data B (at this point in time, the condition data B becomes the selected condition data), the operator of the injection molding machine 10 changes a part of the setting value included in the condition data B to create condition data C. In this way, the operator of the injection molding machine 10 repeatedly fine-tunes the setting value of the condition data while test-executing the injection molding to perform the operation of deriving the optimized molding conditions. During this operation, a plurality of condition data are stored in the external storage device 66.

[0058] [Screen transition of the injection molding machine 10]

[0059] Figure 4 It is a screen transition diagram showing the screen displayed by the display input device 67. Figure 5 This is an example of the condition data selection screen. Figure 6 This is an example of the standby condition preview screen. Figure 7 This is an example of the selection condition preview screen. Figure 8 This is a screen example of the standby condition preview screen in which the display format of the setting value different from the selected condition data is different.

[0060] The control device 60 controls the display input device 67 according to the operator's instructions (input operation). Figure 5 The condition data selection screen shown is displayed on the display. The condition data selection screen is a screen for allowing the operator to select one of the plurality of standby condition data stored in the external storage device 66. The condition data selection screen includes, for example, information identifying each of the plurality of standby condition data (for example, the condition data name and the creation date), radio buttons corresponding to each of the plurality of standby condition data, and a [Preview] icon.

[0061] The control device 60 receives an operation of an operator selecting or canceling a radio button and an operation of an operator clicking a [Preview] icon via the display input device 67. These operations are an example of input operations for selecting one of a plurality of standby condition data stored in the external storage device 66. In addition, these processes are an example of selection processes. And, for example, when the [Preview] icon is clicked while the radio button corresponding to condition data A is selected, the control device 60 causes the [Preview] icon to be displayed. Figure 6 The preview screen of the standby condition shown is displayed on the monitor.

[0062] The standby condition preview screen is a screen that displays a plurality of setting values ​​included in the standby condition data at a glance. More specifically, the standby condition preview screen is a screen that displays a plurality of setting values ​​included in the standby condition data selected through the condition data selection screen (i.e., in the selection process) at a glance. More specifically, the standby condition preview screen is a screen that displays only a plurality of setting values ​​included in the standby condition data in the selected condition data and the standby condition data at a glance. This process is an example of the standby condition display process.

[0063] The standby condition preview screen includes, for example, a plurality of setting values ​​included in the standby condition data, a [select condition] icon, and a [confirm difference] icon. Then, the control device 60 accepts the operation of the operator who clicks the [select condition] icon and the [confirm difference] icon through the display input device 67. On the other hand, the control device 60 does not accept the input operation of changing the setting value in the standby condition preview screen (i.e., the standby condition display process). That is, the operator cannot change the plurality of setting values ​​displayed on the standby condition preview screen through the display input device 67.

[0064] When the [Select Condition] icon on the standby condition preview screen is clicked, the control device 60 displays the [Select Condition] icon instead of the [Select Condition] icon on the standby condition preview screen. Figure 7 The selection condition preview screen shown is displayed on the display. The selection condition preview screen is a screen that displays a plurality of setting values ​​included in the selection condition data at a glance. More specifically, the selection condition preview screen is a screen that displays a plurality of setting values ​​included in the selection condition data and the standby condition data at a glance. This process is an example of a selection condition display process.

[0065] The selection condition preview screen includes, for example, a plurality of setting values ​​included in the selection condition data, a [standby condition] icon, and a [difference confirmation] icon. Furthermore, the control device 60 accepts an operation of the operator who clicks the [standby condition] icon and the [difference confirmation] icon through the display input device 67. In addition, the control device 60 accepts an input operation of changing a setting value through the display input device 67 in the selection condition preview screen (i.e., the selection condition display process). That is, the operator can change a plurality of setting values ​​displayed on the selection condition preview screen through the display input device 67.

[0066] Furthermore, the control device 60 updates the selection condition data stored in the external storage device 66 according to the input operation for changing the set value on the selection condition preview screen. As an example, the control device 60 may set (i.e., overwrite) the set value changed by the display input device 67 to the selection condition data stored in the external storage device 66. As another example, the control device 60 may copy the selection condition data stored in the external storage device 66 and set (i.e., newly create) the set value changed by the display input device 67.

[0067] In addition, when the [Standby Condition] icon on the selection condition preview screen is clicked, the control device 60 displays the [Standby Condition] icon instead of the selection condition preview screen. Figure 6 The standby condition preview screen shown is displayed on the display. That is, the control device 60 selectively displays the selection condition preview screen and the standby condition preview screen. In other words, the control device 60 selectively performs the selection condition display process and the standby condition display process. Clicking the [Selection Condition] icon and the [Standby Condition] icon is an example of an input operation for switching the selection condition display process and the standby condition display process.

[0068] In addition, when the [Difference Confirmation] icon on the standby condition preview screen is clicked, the control device 60 compares the plurality of setting values ​​included in the standby condition data selected through the condition data selection screen with the corresponding setting values ​​of the selected condition data. Figure 8 As shown, the control device 60 displays the same setting values ​​as the setting values ​​corresponding to the selection condition data and the setting values ​​different from the setting values ​​corresponding to the selection condition data among the plurality of setting values ​​of the waiting condition data displayed in a list on the display in different forms.

[0069] In this embodiment, the same setting value as the selection condition data is displayed with a "white background", and a setting value different from the selection condition data is displayed with a "shaded background". However, specific examples of different display methods are not limited to changing the color or pattern of the background, and the color, thickness, font, etc. of the setting value may also be changed.

[0070] In addition, Figure 8 When the [Difference Confirmation] icon is clicked, the control device 60 Figure 6 As shown, all the setting values ​​of the standby condition preview screen are displayed in the same display mode. That is, each time the [Difference Confirmation] icon of the standby condition preview screen is clicked, the control device 60 switches whether to set to a different display mode. Clicking the [Difference Confirmation] icon is an example of an input operation for switching whether to set the setting value that is the same as the selected condition data and the setting value that is different from the selected condition data to different display modes.

[0071] Furthermore, the control device 60 may also display, in a different manner, the setting values ​​that are the same as the corresponding setting values ​​of the standby condition data and the setting values ​​that are different from the corresponding setting values ​​of the standby condition data among the plurality of setting values ​​of the selection condition data displayed on the display at a glance when the [Difference Confirmation] icon on the selection condition preview screen is clicked. As another example, the display of the [Difference Confirmation] icon may also be omitted on the selection condition preview screen.

[0072] [Effects of the Embodiments]

[0073] According to the above embodiment, by displaying only the setting values ​​included in one of the selection condition data and the standby condition data, characters (numbers) can be larger than when displaying the setting values ​​included in both the selection condition data and the standby condition data if the display size is the same.

[0074] In addition, according to the above-mentioned embodiment, among the plurality of setting values ​​included in the standby condition data, the setting values ​​that are the same as the setting values ​​corresponding to the selection condition data and the setting values ​​that are different from the setting values ​​corresponding to the selection condition data are displayed in different ways. Thus, on the standby condition preview screen, it is possible to easily identify the part where the setting value is changed (i.e., the different part between the selection condition data and the standby condition data).

[0075] For example, it is assumed that the operator of the injection molding machine 10 repeatedly performs injection molding tests while generating condition data in the order of condition data A, B, and C. In this case, if the quality of the injection molded product using condition data A is better than that of the injection molded product using condition data C, then the part of condition data A that is different from condition data C ( Figure 8 The shaded area of ​​) is likely to be a setting value that improves the quality of the injection molded product. Figure 8 The standby condition preview screen allows you to quickly identify tips for improving the quality of injection molded products.

[0076] In addition, according to the above-mentioned embodiment, by accepting the change of the setting value through the selection condition preview screen, the setting value can be optimized in the process of repeatedly executing the injection molding test. In addition, the control device 60 can also accept the change of the setting value not only in the selection condition preview screen, but also in the standby condition preview screen.

[0077] Furthermore, according to the above-described embodiment, by comparing the standby condition data selected by the operator among the plurality of standby condition data stored in the external storage device 66 with the selected condition data, it is possible to compare desired condition data based on the result of the injection molding test execution.

[0078] In addition, according to the above-mentioned embodiment, the selection condition preview screen and the standby condition preview screen can be switched by a single input operation (i.e., clicking the [select condition] icon or the [standby condition] icon), so the selection condition data and the standby condition data can be easily compared and studied. In addition, by making the layout of multiple setting values ​​shared in the selection condition preview screen and the standby condition preview screen, the comparison and study becomes easier.

[0079] Furthermore, according to the above-mentioned embodiment, it is possible to switch whether to make the display mode of the set value different, so as to provide the operator with the desired information. However, the [Difference Confirmation] icon may be omitted, and the different parts from the selected condition data may be always clearly indicated on the standby condition preview screen ( Figure 8 the shadow area).

[0080] The above-mentioned embodiments are examples for explaining the present invention, and are not intended to limit the scope of the present invention to these embodiments.
