[0012] 1, an injection molding machine 1 according to this embodiment has a molding machine body 10 including a mold clamping device 2, an injection device 3, and an ejection device 4. The molding machine body 10 is disposed on a base 5. The injection molding machine 1 also has a sensor group 6 (FIG. 2) disposed in the molding machine body 10, and a control unit 7 that controls the molding machine body 10.

[0013] The mold clamping device 2 opens, closes, and clamps a fixed mold 81 and a movable mold 82. The fixed mold 81 and the movable mold 82 form a cavity 83.

[0014] The mold clamping device 2 has a fixed die plate 21, a movable die plate 22, and a mold clamping drive mechanism 23. A fixed side mold 81 is attached to the fixed die plate 21. A movable side mold 82 is attached to the movable die plate 22. The mold clamping drive mechanism 23 has, for example, an electric motor, a ball screw mechanism, and a toggle link mechanism. The mold clamping drive mechanism 23 clamps the fixed side mold 81 and the movable side mold 82 in the front-rear direction (left-right direction in FIG. 1) by the fixed die plate 21 and the movable die plate 22 to generate a mold clamping force.

[0015] The injection device 3 includes a cylinder 31, a nozzle 32, a resin supply unit 33, a heater , a screw 35, and a screw driving mechanism .

[0016] The cylinder 31 has a cylindrical shape. The cylinder 31 is arranged along the front-rear direction. The nozzle 32 is arranged at the tip of the cylinder 31. The resin supply unit 33 is arranged at the rear end of the cylinder 31. The resin supply unit 33 has a hopper that contains powdered or granular resin that is the material of the molded product. The resin supply unit 33 supplies resin to the cylinder 31. The heater 34 is, for example, a band heater, and is arranged on the outer circumferential surface of the cylinder 31. The screw 35 is housed in the cylinder 31 so as to be rotatable and movable forward and backward. The screw drive mechanism 36 has, for example, an electric motor and a ball screw mechanism. The screw drive mechanism 36 rotates and moves the screw 35 forward and backward.

[0017] The removal device 4 has an ejector pin (not shown) and an ejection mechanism 41. The ejection mechanism 41 has, for example, an air cylinder. The ejection mechanism 41 drives the ejector pin to remove the molded product from the movable mold 82.

[0018] The sensor group 6 is composed of a plurality of sensors arranged in each part of the molding machine body 10. The sensor group 6 includes, for example, a sensor that detects the position and speed of the screw 35, a sensor that detects the rotation speed of the screw 35, sensors that detect the pressure (injection pressure, holding pressure, back pressure) applied to the resin in the cylinder 31, a sensor that detects the amount of mold opening and closing, a sensor that detects the mold clamping pressure, a sensor that detects the pressure (mold internal pressure) applied to the resin in the cavity 83, a sensor that detects the amount of ejection pin protrusion, a sensor that detects the pressure applied to the eject pin, a sensor that detects the temperature of each part of the molding machine body 10, and a sensor that detects power value.

[0019] The control unit 7 controls the overall operation of the injection molding machine 1. As shown in Fig. 2, the control unit 7 has a display device 71, an input device 72, a storage device 73, a timer 74, and a control device 75. The control unit 7 is a data display device that displays a plurality of data related to the operation of molding a molded product (molding operation).

[0020] The display device 71 is, for example, a flat panel display such as a liquid crystal display.

[0021] The input device 72 is, for example, an operation key or a touch panel. The operation key is, for example, a key of a hardware keyboard. The touch panel is arranged over the display surface of the display device 71, and is combined with button figures, scroll bar figures, and the like displayed on the display surface to configure software keys. Touching a place on the touch panel that corresponds to the button figures or sliding the scroll bar figure corresponds to operating a software key, that is, inputting an operation into the input device 72.

[0022] The storage device 73 is, for example, a magnetic disk device, a non-volatile memory, etc. The storage device 73 holds information related to molding conditions, etc. The storage device 73 also holds data measured by the sensor group 6.

[0023] The control device 75 has a computer. The control device 75 is connected to the display device 71, the input device 72, the storage device 73, and the timer 74 so as to be able to communicate with them. The control device 75 displays various information on the display device 71 and performs an operation according to an operation input to the input device 72. The display device 71 and the input device 72 may be, for example, a tablet device or a notebook computer connected to the control device 75 by wireless communication. The control device 75 is also connected to the sensor group 6.

[0024] The control device 75 is communicatively connected to the mold clamping drive mechanism 23, the heater 34, the screw drive mechanism 36, and the ejection mechanism 41. The control device 75 controls the mold clamping drive mechanism 23, the heater 34, the screw drive mechanism 36, the ejection mechanism 41, etc. in the molding operation.

[0025] Next, an example of a molding operation executed by the control device 75 will be described.

[0026] The control device 75 controls the heater 34 to heat the cylinder 31 to a predetermined temperature. Before the molding operation, the control device 75 executes a purging operation and measures the amount of resin to be injected for the first time.

[0027] In the molding operation, the control device 75 controls the mold clamping drive mechanism 23 to press the movable mold 82 against the fixed mold 81 to clamp the mold (mold closing operation). Next, the control device 75 controls the screw drive mechanism 36 to move the screw 35 forward (injection operation (filling)). This causes the plasticized resin at the front end of the cylinder 31 to fill the cavity 83. Next, the control device 75 controls the screw drive mechanism 36 to move the screw 35 forward and backward so that a predetermined pressure (holding pressure) is applied to the resin in the cavity 83 (injection operation (holding pressure)).

[0028] Next, the control device 75 controls the screw drive mechanism 36 to rotate and move the screw 35 backward, and supplies (meters) the amount of resin required for one injection to the front end of the cylinder 31 (metering operation). The metering operation is also called a plasticizing operation. In parallel with the metering operation, the control device 75 waits until the resin in the cavity 83 cools and hardens (cooling operation).

[0029] Then, when the cooling operation is completed, the control device 75 controls the mold clamping drive mechanism 23 to open the fixed mold 81 and the movable mold 82 (mold opening operation), and controls the ejection mechanism 41 to remove the molded product from the cavity 83 using the ejector pin (removal operation).

[0030] The steps from the mold closing operation to the ejection operation constitute one molding operation. The control device 75 repeatedly executes the molding operation to mold a molded product. One molding operation is also called one shot.

[0031] The control device 75 measures a plurality of data using the sensor group 6 and the timer 74 during the execution of the molding operation. The control device 75 stores a plurality of data (a plurality of measurement data) measured in one molding operation in the data storage area 73a of the storage device 73 in association with the number of shots and the reference time of the molding operation. The plurality of measurement data includes actual measurement data measured using the sensor group 6 and time data measured (timed) using the timer 74. The number of shots is incremented by one each time a molding operation is executed. The number of shots is the number of molding operations executed, and is also a molding operation number indicating the order of the executed molding operations. The reference time is, for example, the start time of the mold closing operation. The number of shots, the plurality of measurement data, and the reference time are data related to the molding operation. The control device 75 associates a plurality of data related to one molding operation with each other as one data set Ds, and stores the data set Ds in the data storage area 73a in the order of the reference time (chronological order). The data storage area 73a can store a predetermined number of data sets Ds (for example, 100,000 times). When the data storage area 73a becomes full, the control device 75 overwrites the oldest data set Ds with a new data set Ds.

[0032] An example of multiple data related to molding operations stored in the data memory area 73a is shown in Fig. 3. In Fig. 3, multiple data included in one line constitute one data set Ds, and the data set Ds is arranged from top to bottom in order of the most recent reference time. In Fig. 3, the measurement data is arranged from left to right in the order of monitor item number (described later).

[0033] The control unit 7 has a monitor screen for displaying a plurality of data related to the molding operation, and a monitor item selection screen for selecting a monitor item indicating the type of data to be displayed on the monitor screen. The control device 75 displays the monitor screen and the monitor item selection screen on the display device 71. The monitor screen displays data corresponding to monitor items previously selected by the operator using the monitor item selection screen. During the execution of the molding operation, the monitor screen displays a plurality of data related to the molding operation substantially in real time.

[0034] An example of the monitor item selection screen Gn is shown in Fig. 4. The monitor item selection screen Gn includes a monitor item table Gn1 and a selected monitor item Gn2. The monitor item table Gn1 displays a list of monitor items that can be selected by the operator. In the monitor item table Gn1, each monitor item is displayed with its monitor item name and its number (monitor item number) arranged side by side. The selected monitor item Gn2 is set with the monitor item number to be displayed on the monitor screen.

[0035] 5 to 10 show an example of a monitor screen G. The monitor screen G includes a setting display section Gs, a statistics display section Gt, a statistical shot count display section Gh, a first data display section G1, and a second data display section G2. The monitor screen G also includes a split screen display switching button B1 and a statistics clear button B2, which are software keys.

[0036] The setting display section Gs is disposed at the top of the monitor screen G. The setting display section Gs displays setting information related to multiple preselected monitor items. The setting display section Gs displays the "monitor item name", "unit", "max", and "min" related to each monitor item, arranged in order from top to bottom. The "max" in the setting display section Gs is the upper limit of the normal range of data measured for the monitor item. The "min" in the setting display section Gs is the lower limit of the normal range of data measured for the monitor item.

[0037] The statistical display section Gt is disposed at the bottom of the monitor screen G. The statistical display section Gt displays statistical information related to multiple monitor items selected in advance. The statistical display section Gt displays "max," "min," "range=R," "average=X," "deviation=σ," "R / X[%]," and "3σ / X[%]" related to each monitor item, arranged in order from top to bottom. "max" in the statistical display section Gt is the maximum value of the data measured for the monitor item. "min" in the statistical display section Gt is the minimum value of the data measured for the monitor item. "Range=R" is the value obtained by subtracting "min" from "max." "Average=X" is the average value of the data measured for the monitor item. "Deviation=σ" is the standard deviation of the data measured for the monitor item. "R / X[%]" is the value obtained by dividing "range=R" by "average=X." "3σ / X [%]" is the value obtained by dividing three times the standard deviation of the data measured for the monitored item by "average = X."

[0038] The statistical shot number display section Gh is disposed to the right of the statistical display section Gt. The statistical shot number display section Gh displays the number of shots (the number of molding operations) used in the statistics.

[0039] The monitor screen G has a data display area D (area surrounded by a dashed line in FIG. 5) between the setting display section Gs and the statistics display section Gt. The data display area D can display a first data display section G1 and a second data display section G2. The monitor screen G has a single screen display state S1 in which only the first data display section G1 is displayed over the entire data display area D, and a split screen display state S12 in which the first data display section G1 and the second data display section G2 are displayed in the data display area D.

[0040] The first data display section G1 is displayed in the data display area D. The first data display section G1 displays a plurality of data related to a molding operation. The first data display section G1 displays one data set Ds (a plurality of data surrounded by a dashed line in FIG. 5) including a plurality of data related to one molding operation in one row. One data set Ds includes the number of shots, a plurality of data (measurement data) measured for a plurality of monitor items selected in advance, and a reference time of the molding operation, and these are displayed in order from left to right in the first data display section G1. The first data display section G1 also displays a plurality of data sets Ds from top to bottom in order of newer reference times. That is, the data sets Ds displayed at the top have newer reference times than the data sets Ds displayed at the bottom. The first data display section G1 has a scroll bar SB, which is a software key, and is configured to be able to scroll the plurality of data sets Ds up and down. The plurality of data sets Ds displayed in the first data display section G1 are scrolled up and down in response to sliding of the scroll bar SB. Sliding the scroll bar SB corresponds to an operation of vertically scrolling the multiple data sets Ds displayed in the first data display section G1. The multiple data sets Ds displayed in the first data display section G1 may be scrollable horizontally. In the first data display section G1, measurement data that falls outside the normal range is highlighted (provided that a value other than 0 is set in "max" or "min" in the setting display section Gs). Note that although the dashed line indicating the data display area D and the dashed line indicating the data sets Ds are only shown in FIG. 5, the data display area D and the data sets Ds are the same in FIGS. 6 to 10.

[0041] The second data display section G2 is displayed below the first data display section G1 in the data display area D. A plurality of data related to the molding operation is displayed on the second data display section G2. The second data display section G2 has the same configuration as the first data display section G1, so a detailed description is omitted.

[0042] The split screen display switching button B1 is disposed above the setting display section Gs on the monitor screen G.

[0043] When the split screen display switching button B1 is touched in the single screen display state S1, the control device 75 displays the first data display section G1 and the second data display section G2 side-by-side in the data display area D, and transitions to the split screen display state S12. Note that touching the split screen display switching button B1 in the single screen display state S1 corresponds to inputting a screen split operation to the input device 72.

[0044] When the split screen display switching button B1 is touched in the split screen display state S12, the control device 75 erases the second data display section G2, displays only the first data display section G1 in the data display area D, and transitions to the single screen display state S1. Touching the split screen display switching button B1 in the split screen display state S12 corresponds to inputting a screen split cancellation operation to the input device 72.

[0045] The statistics clear button B2 is located to the right of the statistics display section Gt and below the statistical shot count display section Gh. When the statistics clear button B2 is touched, the number of shots is cleared, the statistical shot count display section Gh becomes 0, and the statistical information in the statistics display section Gt is reset.

[0046] Next, the monitor screen G displayed on the display device 71 by the control device 75 while the molding operation is being performed will be described with reference to Figs.

[0047] The control device 75 continuously executes the molding operation, measures a plurality of pieces of data relating to the molding operation, and stores the data in the data storage area 73 a of the storage device 73 .

[0048] When an operator inputs an operation to display the monitor screen G on the input device 72 during the molding operation, the control device 75 displays the monitor screen G on the display device 71 (FIG. 5). At this time, the control device 75 displays only the first data display section G1 in the data display area D (single screen display state S1). The control device 75 also reads out a data set Ds from the data storage area 73a, and arranges the data set Ds with the most recent reference time in the top row of the first data display section G1, and displays multiple data sets Ds in the first data display section G1 from top to bottom in order of most recent reference time.

[0049] When a molding operation being executed is completed and a new data set Ds related to the molding operation is stored in the data storage area 73a, the control device 75 reads out the new data set Ds from the data storage area 73a. The data set Ds read out at this time is the most recent data set Ds. The control device 75 then shifts the multiple data sets Ds displayed in the first data display section G1 down by one row, and displays the new data set Ds read out from the data storage area 73a in the top row of the first data display section G1 (FIG. 6).

[0050] When the operator slides the scroll bar SB in the first data display section G1 up or down, the control device 75 scrolls the multiple data sets Ds displayed in the first data display section G1 up or down in response to the slide (FIG. 7). As shown in FIG. 7, this slide operation causes the first data display section G1 to display the data set Ds including multiple data related to relatively old molding operations.

[0051] When the operator touches the split screen display switching button B1 in the single screen display state S1, the control device 75 (A) moves the bottom end of the first data display section G1 upward (near the vertical center of the data display area D) to reduce the vertical size of the first data display section G1, and displays a second data display section G2 having the same vertical size as the first data display section G1 below the first data display section G1, (B) reads a data set Ds from the data memory area 73a, places the most recent data set Ds in the top row of the first data display section G1, and displays multiple data sets Ds in the first data display section G1 arranged from top to bottom in chronological order of the most recent reference time, and (C) reads a data set Ds from the data memory area 73a, and displays the multiple data sets Ds that were displayed in the first data display section G1 immediately before the split screen display switching button B1 was touched in the second data display section G2 arranged from top to bottom in chronological order (Figure 8). This causes a transition from the single screen display state S1 to the split screen display state S12.

[0052] At this time, the multiple data sets Ds displayed on the second data display section G2 are the multiple data sets Ds that were displayed on the first data display section G1 at a position D2 (a portion surrounded by a dashed line in FIG. 7) corresponding to the second data display section G2 immediately before the split screen display switching button B1 was touched. In this way, the multiple data sets Ds displayed on the first data display section G1 immediately before the split screen display switching button B1 was touched are displayed on the second data display section G2 without changing their respective positions. This makes it possible to prevent the operator from losing sight of the data set Ds that he or she was paying attention to due to a change in the position of the data sets Ds. Note that when the second data display section G2 is displayed, the control device 75 may display on the second data display section G2 the data sets Ds that were displayed at a position other than the position D2 on the first data display section G1.

[0053] When the operator slides the scroll bar SB of the first data display section G1 up or down, the control device 75 scrolls the multiple data sets Ds displayed in the first data display section G1 up or down in accordance with the slide. When the operator slides the scroll bar SB of the second data display section G2 up or down, the control device 75 scrolls the multiple data sets Ds displayed in the second data display section G2 up or down in accordance with the slide.

[0054] When the molding operation being executed in the split screen display state S12 is completed and a new data set Ds related to that molding operation is stored in the data memory area 73a, the control device 75 (D) reads from the data memory area 73a the next most recent data set Ds after the data set Ds displayed in the top row of the first data display section G1, (E) moves the multiple data sets Ds displayed in the first data display section G1 down one row and displays the data set Ds read from the data memory area 73a in the top row of the first data display section G1, and (F) maintains the display of the multiple data sets Ds in the second data display section G2 (Figure 9).

[0055] Specifically, (i) when the most recent data set Ds is displayed on the top line of the first data display section G1, when the molding operation being performed is completed and a new data set Ds related to that molding operation is stored in the data storage area 73a, the control device 75 reads out the new data set Ds from the data storage area 73a, moves the multiple data sets Ds displayed on the first data display section G1 down by one line, and displays the new data set Ds read out from the data storage area 73a on the top line of the first data display section G1. The control device 75 maintains (does not change) the display of the multiple data sets Ds on the second data display section G2.

[0056] Or, (ii) when a data set Ds older than the newest data set Ds is displayed on the top row of the first data display section G1, the molding operation being executed is completed and a new data set Ds related to the molding operation is stored in the data storage area 73a, the control device 75 reads out from the data storage area 73a the data set Ds (target data set Dst) next to the old data set Ds displayed on the top row of the first data display section G1, moves the multiple data sets Ds displayed on the first data display section G1 down by one row, and displays the target data set Dst read out from the data storage area 73a on the top row of the first data display section G1. The control device 75 maintains (does not change) the display of the multiple data sets Ds on the second data display section G2.

[0057] That is, the plurality of data sets Ds displayed on the first data display section G1 are automatically scrolled down by one line each time a molding operation being executed is completed, and the plurality of data sets Ds displayed on the second data display section G2 do not change. Note that the control device 75 performs the operations related to the first data display section G1 shown in the above (i) and (ii) regardless of whether the display is in the single screen display state S1 or the split screen display state S12.

[0058] When the operator touches the split screen display switching button B1 in the split screen display state S12, the control device 75 (G) erases the second data display section G2, moves the bottom end of the first data display section G1 downward (to the bottom end of the data display area D) to increase the vertical size of the first data display section G1, and (H) reads out the data set Ds from the data storage area 73a, arranges the most recent data set Ds in the top row of the first data display section G1, and displays multiple data sets Ds in the first data display section G1 from top to bottom in order of newest reference time. This causes a transition from the split screen display state S12 to the single screen display state S1. Figures 5 to 7 and 10 show the monitor screen G in the single screen display state S1. Figures 8 and 9 show the monitor screen G in the split screen display state S12.

[0059] The control device 75 updates the statistical information displayed in the statistical display section Gt and the number of shots displayed in the statistical shot number display section Gh every time one molding operation being executed is completed.

[0060] As described above, the injection molding machine 1 has a molding machine main body 10 that molds a molded product, and a control unit 7. The control unit 7 is a data display device that displays multiple data related to a molding operation. The control unit 7 has a display device 71 that displays a monitor screen G, an input device 72 to which an operation by an operator is input, and a control device 75. The monitor screen G has a data display area D that can display a first data display section G1 and a second data display section G2. In the first data display section G1 and the second data display section G2, a data set Ds including multiple data related to one molding operation is displayed in one line, and the multiple data sets Ds are displayed arranged in chronological order in the vertical direction.

[0061] When the split screen display switching button B1 is touched while only the first data display section G1 is displayed in the data display area D (single screen display state S1), the control device 75 reduces the vertical size of the first data display section G1 and displays the second data display section G2 vertically side by side with the first data display section G1 in the data display area D.

[0062] When the split screen display switching button B1 is touched while the first data display section G1 and the second data display section G2 are displayed in the data display area D (split screen display state S12), the control device 75 erases the second data display section G2 and increases the vertical size of the first data display section G1.

[0063] As a result of doing so, the first data display section G1 and the second data display section G2 can be displayed in the data display area D of the monitor screen G, and a data set Ds including a plurality of data related to a molding operation can be displayed in each of them. Therefore, by displaying a data set Ds including a plurality of data related to one molding operation in the first data display section G1 and a data set Ds including a plurality of data related to another molding operation in the second data display section G2, it becomes unnecessary to compare the data while scrolling up and down, and it is possible to easily compare these data. Therefore, the complicated operation of comparing data while scrolling up and down is unnecessary.

[0064] Moreover, when the split screen display switching button B1 is touched in the single screen display state S1, the control device 75 (A) moves the bottom end of the first data display section G1 upward to reduce the vertical size of the first data display section G1 and displays the second data display section G2 below the first data display section G1, (B) displays the multiple data sets Ds arranged in chronological order from top to bottom in the first data display section G1 so that the most recent data set Ds is placed in the top row, and (C) displays the multiple data sets Ds that were displayed in the first data display section G1 immediately before the split screen display switching button B1 was touched in chronological order from top to bottom in the second data display section G2. In this way, immediately after the transition from the single screen display state S1 to the split screen display state S12, the multiple data sets Ds including the most recent data set Ds are displayed in the first data display section G1, and the multiple data sets Ds that were displayed in the first data display section G1 immediately before the transition to the second data display section G2 are displayed. Therefore, the plurality of data sets Ds including the newest data set Ds can be easily compared with the plurality of data sets Ds displayed in the first data display section G1 immediately before the transition.

[0065] Furthermore, a plurality of data relating to the molding operation are stored in the storage device 73 (data storage area 73a). When a new data set Ds is stored in the storage device 73 in the split screen display state S12, the control device 75 (D) reads out from the storage device 73 the next new data set Ds after the data set Ds displayed in the top row of the first data display section G1, (E) moves the plurality of data sets Ds displayed in the first data display section G1 down by one row and displays the data set Ds read out from the storage device 73 in the top row of the first data display section G1, and (F) maintains the display of the plurality of data sets Ds in the second data display section G2. In this manner, the plurality of data sets Ds displayed in the first data display section G1 are automatically scrolled down by one row each time the molding operation being performed is completed, and the plurality of data sets Ds displayed in the second data display section G2 do not change. Therefore, it is possible to visually compare the plurality of data sets Ds displayed in the first data display section G1, the display of which is automatically updated, with the plurality of data sets Ds displayed in the second data display section G2, the display of which is not changed.

[0066] Furthermore, when the split screen display switching button B1 is touched in the split screen display state S12, the control device 75 (G) erases the second data display section G2, moves the bottom end of the first data display section G1 downward to increase the vertical size of the first data display section G1, and (H) displays the multiple data sets Ds in the first data display section G1 in order from top to bottom so that the most recent data set Ds is placed in the top row. In this way, immediately after transitioning from the split screen display state S12 to the single screen display state S1, the multiple data sets Ds including the most recent data set Ds are displayed in the first data display section G1. Therefore, it is possible to check the multiple data sets Ds including the most recent data set Ds immediately after the transition.

[0067] Furthermore, the first data display section G1 has a scroll bar SB through which an operation is input to vertically scroll the multiple data sets Ds displayed on the first data display section G1. The second data display section G2 has a scroll bar SB through which an operation is input to vertically scroll the multiple data sets Ds displayed on the second data display section G2. That is, the first data display section G1 and the second data display section G2 are configured to be able to vertically scroll the multiple data sets Ds. In this way, a desired data set Ds can be displayed on the first data display section G1 and the second data display section G2 by vertically scrolling the multiple data sets Ds.
