DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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] 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.

[0012] 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.

[0013] 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 to move the movable die plate 25 rightward, the fixed die 22 and the movable die 24 are clamped.

[0014] 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.

[0015] 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 for heating the heating cylinder 31 is attached to the outer circumferential surface of the heating cylinder 31.

[0016] 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.

[0017] 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.

[0018] More specifically, when the injection motor 37 is rotated in the forward direction, the screw 32 moves (forward) toward the tip of the heating cylinder 31 (i.e., the nozzle 36). On the other hand, when the injection motor 37 is rotated in the reverse direction, the screw 32 moves (rearward) toward the base end of the heating cylinder 31 (i.e., the side opposite the nozzle 36). 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 is referred to as the "forward limit," and the position farthest from the nozzle 36 is referred to as the "rear limit." In addition, the terms "forward rotation" and "reverse rotation" of the injection motor 37 do not specify an absolute direction of rotation, but merely specify a relative relationship (i.e., forward rotation and reverse rotation are rotations in opposite directions).

[0019] 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.

[0020] 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.

[0021] [Configuration of control device 60] 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.

[0022] 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).

[0023] 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, and the metering motor 38 based on various signals output from a rotary encoder 64 and a load cell 65 (pressure sensor).

[0024] 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).

[0025] 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.

[0026] 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.

[0027] An external storage device 66 is also connected to the control device 60. The external storage device 66 is an example of a memory capable of storing a plurality of condition data (see FIG. 3). For example, a hard disk drive (HDD) or a universal serial bus (USB) memory can be used as the external storage device 66. However, the memory may be a RAM 63 mounted on the control device 60. Details of the condition data will be described later with reference to FIG. 3.

[0028] Furthermore, a display input device 67 is 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.

[0029] [Example of condition data] Fig. 3 is an example of multiple pieces of condition data stored in the external storage device 66. As shown in Fig. 3, the external storage device 66 is capable of storing multiple pieces of condition data. The condition data is data indicating the operating conditions of injection molding by the injection molding machine 10 (hereinafter referred to as "molding conditions"). The condition data is, for example, binary data or text data in which multiple setting values ​​are arranged in a predetermined order.

[0030] The condition data according to the present embodiment includes, for example, a condition data name, a creation date and time, and a plurality of set values ​​(position, injection speed, primary pressure, dwell pressure, timer, and dwell pressure speed). The set values ​​included in the condition data are not limited to the above-mentioned examples. The condition data may include not only set values ​​indicating the operation of the injection device 30, but also set values ​​indicating the operation of the mold clamping device 20.

[0031] 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 and time is the date and time when the condition data was created. Furthermore, when the condition data is updated through a selection condition preview screen described later, the creation date and time may be set to the updated date and time.

[0032] The set value "position" indicates the position (mm) of the tip of the screw 32 within the heating cylinder 31. More specifically, the set value "position" indicates the speed switching position of the screw 32 when injecting the plasticized resin (hereinafter referred to as the "injection process"). It should be noted that the set value "position" can include multiple switching positions. Furthermore, the position within the heating cylinder 31 can be expressed as the distance from the forward movement limit toward the base end of the heating cylinder 31, with the forward movement limit being 0 mm. The position of the tip of the screw 32 is detected by the rotary encoder 64.

[0033] The set value "injection speed" indicates the forward speed (mm / s) of the screw 32 in the injection process. More specifically, the set value "injection speed" may include a plurality of speeds switched at a plurality of switching positions indicated by the set value "position". In other words, the forward speed indicated by the set 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.

[0034] The set value "primary pressure" indicates the maximum pressure (MPa) applied to the screw 32 in the injection process. That is, in the injection process, speed control by the set value "injection speed" takes precedence, but when the pressure indicated by the set value "primary pressure" is reached, pressure control is performed so as not to exceed that pressure. The pressure applied to the screw 32 is detected by the load cell 65.

[0035] 7, 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). The control device 60 also controls the injection speed so that the injection speed approaches a set value within a range that does not exceed the maximum pressure (=50 (MPa)) applied to the screw 32 during the injection process.

[0036] The set value "holding pressure" indicates the pressure (MPa) that the screw 32 applies to the plasticized resin injected into the mold 21. In other words, the set value "holding pressure" indicates the pressure that the screw 32 applies in the forward direction after the injection of the plasticized resin is completed (hereinafter, this process will be referred to as the "holding pressure process"). The set value "holding pressure" can include multiple pressures. The pressure applied to the screw 32 is detected by the load cell 65.

[0037] The set value "timer" indicates the switching timing (sec) of the multiple pressures indicated by the set value "holding pressure". The set value "timer" indicates the elapsed time from the end of the injection process (start of the holding pressure process). The set value "timer" can include multiple switching timings. The elapsed time is measured by a system clock installed in the control device 60.

[0038] The set value "holding pressure speed" indicates the maximum speed (mm / s) of the screw 32 in the holding pressure process. That is, in the holding pressure process, the pressure control by the set value "holding pressure" takes precedence, but when the speed indicated by the set value "holding pressure speed" is reached, the speed is controlled so as not to exceed that speed. The forward speed of the screw 32 is detected by the rotary encoder 64.

[0039] 7, the controller 60 applies a pressure of 10.0 MPa to the plasticized resin in the mold 21 for 0.50 sec from the start of the pressure holding process, then applies a pressure of 20.0 MPa for the next 0.50 sec, applies a pressure of 15.0 MPa for the next 0.50 sec, and applies a pressure of 10.0 MPa for the next 0.50 sec. Also, the controller 60 controls the pressure so that the pressure approaches the set value within a range that does not exceed the maximum forward speed of the screw 32 (=10 mm / s) during the pressure holding process.

[0040] One of the multiple condition data stored in the external storage device 66 is "selected condition data" that has been selected in advance via the display input device 67. On the other hand, the condition data stored in the external storage device 66 that is different from the selected condition data is "standby condition data". In other words, the external storage device 66 includes only one selected condition data and one or more (in this embodiment, multiple) standby condition data. In this embodiment, the condition data C identified by the condition data name "DATA C" is defined as "selected condition data", and the condition data A and B identified by the condition data names "DATA A" and "DATA B" are defined as "standby condition data".

[0041] The control device 60 controls the 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, the operation of the injection molding machine 10 during injection molding (in other words, the quality of the injection molded product) may differ depending on the selection of different condition data. On the other hand, the standby condition data is condition data that is not currently used for injection molding. However, it is possible to switch between the selected condition data and the standby condition data (that is, to make one of the standby condition data the new selected condition data) by a switching operation via the display input device 67.

[0042] For example, the operator of the injection molding machine 10, taking into account the results of injection molding using condition data A (at this point, condition data A is the selected condition data), changes some of the setting values ​​contained in condition data A to create condition data B. Next, taking into account the results of injection molding using condition data B (at this point, condition data B is the selected condition data), changes some of the setting values ​​contained in condition data B to create condition data C. In this way, the operator of the injection molding machine 10 performs test injection molding while repeatedly fine-tuning the setting values ​​of the condition data, and performs the task of deriving optimal molding conditions. In the course of this task, a plurality of condition data are stored in the external storage device 66.

[0043] [Screen transition of injection molding machine 10] Fig. 4 is a screen transition diagram of the screens displayed on the display input device 67. Fig. 5 is an example of a condition data selection screen. Fig. 6 is an example of a standby condition preview screen. Fig. 7 is an example of a selection condition preview screen. Fig. 8 is an example of a standby condition preview screen in which the display mode of setting values ​​that differ from the selection condition data is changed.

[0044] The control device 60 displays the condition data selection screen shown in Fig. 5 on the display in accordance with an instruction (input operation) of the operator via the display input device 67. The condition data selection screen is a screen for allowing the operator to select one of the multiple standby condition data stored in the external storage device 66. The condition data selection screen includes, for example, information identifying each of the multiple standby condition data (for example, the condition data name and creation date and time), a radio button corresponding to each of the multiple standby condition data, and a [Preview] icon.

[0045] The control device 60 accepts an operator's operation of selecting or deselecting a radio button and an operator's operation of tapping a [Preview] icon through the display input device 67. These operations are an example of an input operation of selecting one of a plurality of standby condition data stored in the external storage device 66. These processes are also an example of a selection process. Then, for example, when the radio button corresponding to the condition data A is selected and the [Preview] icon is tapped, the control device 60 causes the display to display the standby condition preview screen shown in FIG. 6.

[0046] The standby condition preview screen is a screen that displays a list of multiple setting values ​​included in the standby condition data. More specifically, the standby condition preview screen is a screen that displays a list of multiple setting values ​​included in the standby condition data selected through the condition data selection screen (i.e., in the selection process). More specifically, the standby condition preview screen is a screen that displays a list of only multiple setting values ​​included in the standby condition data, out of the selected condition data and the standby condition data. This process is an example of a standby condition display process.

[0047] The standby condition preview screen includes, for example, a plurality of setting values ​​included in the standby condition data, a [selection condition] icon, and a [difference check] icon. The control device 60 accepts an operator's operation of tapping the [selection condition] icon and the [difference check] icon through the display input device 67. On the other hand, the control device 60 does not accept an input operation for changing the setting values ​​on the standby condition preview screen (i.e., the standby condition display process). In other words, the operator cannot change the plurality of setting values ​​displayed on the standby condition preview screen through the display input device 67.

[0048] When the [Selection Condition] icon on the standby condition preview screen is tapped, the control device 60 causes the display to display the selection condition preview screen shown in FIG. 7 instead of the standby condition preview screen. The selection condition preview screen is a screen that displays a list of multiple setting values ​​included in the selection condition data. More specifically, the selection condition preview screen is a screen that displays a list of only multiple setting values ​​included in the selection condition data, out of the selection condition data and the standby condition data. This process is an example of a selection condition display process.

[0049] 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 check] icon. The control device 60 accepts an operator's operation of tapping the [standby condition] icon and the [difference check] icon through the display input device 67. The control device 60 also accepts an input operation for changing a setting value on the selection condition preview screen (i.e., the selection condition display process) through the display input device 67. That is, the operator can change a plurality of setting values ​​displayed on the selection condition preview screen through the display input device 67.

[0050] Then, the control device 60 updates the selection condition data stored in the external storage device 66 according to an input operation that changes the setting value on the selection condition preview screen. As one example, the control device 60 may set (i.e., overwrite) the setting value changed through 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 setting value changed through the display input device 67.

[0051] Furthermore, when the [Standby Condition] icon on the selection condition preview screen is tapped, the control device 60 causes the display to display the standby condition preview screen shown in FIG. 6 instead of the selection condition preview screen. 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 executes the selection condition display process and the standby condition display process. Tapping the [Selection Condition] icon and the [Standby Condition] icon is an example of an input operation for switching between the selection condition display process and the standby condition display process.

[0052] Furthermore, when the [Check Difference] icon on the standby condition preview screen is tapped, the control device 60 compares each of the multiple setting values ​​included in the standby condition data selected through the condition data selection screen with the corresponding setting value of the selected condition data. Then, as shown in Fig. 8, the control device 60 displays, among the multiple setting values ​​of the standby condition data listed on the display, the setting values ​​that are the same as the corresponding setting value of the selected condition data and the setting values ​​that are different from the corresponding setting value of the selected condition data in different modes.

[0053] In this embodiment, the setting values ​​that are the same as the selection condition data are displayed with a "white background," and the setting values ​​that are different from the selection condition data are displayed with a "hatched background." However, specific examples of different display modes are not limited to changing the background color and pattern, and the color, thickness, font, etc. of the setting values ​​may be changed.

[0054] Furthermore, when the [Check Difference] icon in Fig. 8 is tapped, the control device 60 displays all the setting values ​​on the standby condition preview screen in the same display mode as shown in Fig. 6. That is, the control device 60 switches whether to display a different display mode each time the [Check Difference] icon on the standby condition preview screen is tapped. Tapping the [Check Difference] icon is an example of an input operation that switches whether to display a setting value that is the same as the selection condition data and a setting value that is different from the selection condition data in different display modes.

[0055] Furthermore, when the [Check Difference] icon on the selection condition preview screen is tapped, the control device 60 may display, in different modes, 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 multiple setting values ​​of the selection condition data listed on the display. As another example, the display of the [Check Difference] icon may be omitted on the selection condition preview screen.

[0056] [Effects of the embodiment] According to the above embodiment, by displaying a list of only the setting values ​​contained in either the selection condition data or the standby condition data, it is possible to make the letters (numbers) larger, assuming the same display size, compared to displaying a list of the setting values ​​contained in both the selection condition data and the standby condition data.

[0057] According to the above embodiment, among the multiple setting values ​​included in the standby condition data, the setting values ​​that are the same as the corresponding setting values ​​in the selection condition data and the setting values ​​that are different from the corresponding setting values ​​in the selection condition data are displayed in different modes. This makes it easy to identify the parts where the setting values ​​have been changed (i.e., the parts where the selection condition data and the standby condition data differ) on the standby condition preview screen.

[0058] For example, suppose 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, it is highly likely that the difference between condition data A and condition data C (hatched portion in FIG. 8) is a setting value that improves the quality of the injection molded product. Therefore, the operator can quickly identify hints for improving the quality of the injection molded product through the standby condition preview screen in FIG. 8.

[0059] According to the above embodiment, the setting values ​​can be optimized in the process of repeating the injection molding test execution by accepting changes to the setting values ​​through the selection condition preview screen. Note that the control device 60 may accept changes to the setting values ​​not only through the selection condition preview screen but also through the standby condition preview screen.

[0060] Furthermore, according to the above embodiment, by comparing the waiting condition data selected by the operator from among the multiple waiting condition data stored in the external storage device 66 with the selected condition data, it becomes possible to compare the desired condition data based on the results of the injection molding test execution.

[0061] According to the above embodiment, the selection condition preview screen and the standby condition preview screen can be switched by a single input operation (i.e., tapping the [selection condition] icon or the [standby condition] icon), so that the selection condition data and the standby condition data can be easily compared. Furthermore, by making the layout of multiple setting values ​​common to the selection condition preview screen and the standby condition preview screen, the comparison and examination becomes even easier.

[0062] Furthermore, according to the above embodiment, it is possible to provide the operator with desired information by making it possible to switch whether or not to display the set values ​​differently. However, the [Check Difference] icon may be omitted, and the differences from the selected condition data (hatched areas in FIG. 8) may be always clearly indicated on the standby condition preview screen.

[0063] 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]
