Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display screen control method for a molding machine equipped with a display device for displaying various information images in various display mode images such as setting condition display mode images and measured data display mode images. is there.

[0002]

2. Description of the Related Art Recent molding machines such as microcomputer-controlled injection molding machines and die casting machines are equipped with a display device such as a color CRT display or a color LCD display. Various setting mode images for setting or confirming molding operation conditions for operation, various monitor mode images for displaying actual measurement data of many monitor items during automatic molding operation, inspection items automatically at regular inspection time Is displayed to display a periodic inspection mode image for prompting periodic inspection.

[0003]

[Problems to be Solved by the Invention] By the way, the products (molded products) molded by injection molding machines and the like are becoming more and more precise, and accordingly, they are displayed in the setting mode image and the monitor mode image. The number of set values and measured data is increasing, and this tendency is expected to increase in the future. However, since the size of the display screen of the display device is limited, when all items are displayed in one setting mode image such as a charge stroke setting image or an injection stroke setting image, characters or the like are inevitably displayed. However, there is a problem that it is difficult to see what the set value is because similar characters are lined up because the character spacing is narrowed and it becomes very difficult to see.

In order to solve this, for example, one setting mode image (screen) may be divided into a plurality of pieces, and characters and the like may be individually displayed at a size that is easy to see and at intervals. There is a problem that the number of images (screens) to be prepared unnecessarily increases, the amount of data such as frame image information handled by the display program increases, and the load on software and the load on memory capacity increase. On the other hand, it is conceivable that the operator cuts out a part of the image on the display screen by moving the cursor or the like and enlarges and displays this cut-out specified portion to the full display screen. It is burdensome, and since the enlargement / reduction calculation conversion processing of the image data has to be performed at an arbitrary enlargement / reduction rate, the load on software increases.

The present invention has been made in view of the above points,
The purpose is to make it possible to enlarge a part of the image to a size that makes it easy to see, and the enlargement / reduction operation is easy and reliable, and the molding machine does not place a heavy burden on software or hardware. To realize the display screen control method.

[0006]

In order to achieve the above object, the present invention comprises a display device capable of displaying various display mode images such as a setting condition display mode image and an actual measurement data display mode image by operator's selection. In the display screen control method for a molding machine, the image of the area fixedly set in a part of the display screen of the display device is an image of the maximum enlargement ratio in which the image currently displayed on the display screen is predetermined. If not, the image of the area fixedly set in a part of the display screen is displayed in almost every part of the display screen for each enlargement display instruction by the operator in one step at a preset enlargement ratio. When the image currently displayed on the display screen is not an image with a predetermined reference magnification, the entire display screen is displayed for each reduction display instruction from the operator. The current image being displayed is to show reduced back to the display image of one step before magnification part matches the fixedly set region of the display screen.

[0007]

When the operator calls up the desired display mode image, the display data such as characters, symbols and ruled lines of the specified display mode image are stored in the image data generating / storing section in the microcomputer, as well as the arrangement information and the additional information. Generated and stored, based on the stored data of this image data generation and storage unit, the image data to be displayed in the frame buffer is written,
An image is displayed on the display screen of the display device by the output of the frame buffer. In the initial state in which the desired display mode image is called and displayed on the display screen, the displayed image has the size of the reference magnification and cannot be further reduced. When the operator pushes the enlargement instruction key in this state, for example, 1 / of the preset display screen is displayed.
The data corresponding to the image in the predetermined area (fixed cutout area) 4 is automatically cut out from the image data generation / storage section by the display control section in the microcomputer, and this becomes an image for almost one screen. The data is converted and written in the frame buffer as described above, and the portion corresponding to the fixed cutout area of the previous image is enlarged and displayed on the display screen almost over the entire screen. When the operator further pushes the enlargement instruction key in this state, the contents of the frame buffer are rewritten and updated by the same process, and the portion corresponding to the fixed cutout area of the once enlarged image is further enlarged and displayed almost on the entire screen. To be done. On the other hand, when the operator pushes the reduction instruction key from this state, the display control unit
Automatically cut out the image data of the area currently being enlarged and displayed on the screen and the image data of a predetermined area (three times the area currently being displayed) adjacent thereto from the image data generation / storage section. Then, it is converted so that it becomes an image for almost one screen and written in the frame buffer,
An image corresponding to the enlargement ratio of one step before is displayed on the display screen (reduced display by one step). When the operator further pushes the reduction instruction key in this state, the contents of the frame buffer are rewritten and updated by the same process, and the image is displayed at the initial reference magnification.

By doing so, it is possible to enlarge a part of the image to a size in which it is easy to see, and it becomes easy to confirm the operating condition set value and the like. Further, since the microcomputer automatically cuts out the image data, the operator only has to instruct the enlargement or reduction, so that the enlargement / reduction operation is easy and reliable. Also, the image data generation / storage unit has 1
Since the entire data of one display mode image is stored in a batch, the amount of data to be handled is smaller than the case where one display mode image is divided into a plurality of screen data, and the image data is cut out. Since the area is constant and the enlargement / reduction ratio is also constant, it is possible to obtain a system in which arithmetic conversion processing is easy (construction of a program is easy) and there is no significant burden in terms of software and hardware.

Thus, in the state shown in FIG. 5, the function keys F1 to F7 function as selection input keys for the functions indicated by characters in the figure. When the "function" selection key 9-1 is pushed once from the state of FIG. 5, this time, the function key F1 of the function key input device 5 as shown in FIG. 6 is displayed at the bottom of the display screen of the display device 6. In the state shown in FIG. 6, the function keys F1, F2 and F5 to F8 function as selection input keys for the functions indicated by characters in the figure.
In the present embodiment, some function switching of the function keys F1 to F8 by the "function" selection key 9-1 is prepared in addition to those shown in FIGS. 5 and 6, and these illustrations avoid redundancy. Therefore, although omitted, it should be understood that the function keys F1 to F8 can be switched in a loop by repeating the push of the “function” selection key 9-1.

The microcomputer 1 shown in FIG.
Controlling the entire molding process such as injection operation, mold opening / closing operation, ejecting operation, calculation / storing processing of measured data, calculation / judging processing such as abnormality judgment processing, control processing of the output image of the display device 5, etc. To do. This microcomputer 1 actually has various I / O interfaces, ROM, RAM,
Although it is configured by including a CPU and the like, and executes various processes by various programs created in advance, in the present embodiment, the molding condition setting storage unit 12, the molding process control unit 13, the measured value storage unit 14, and the display. The following description will be made assuming that the control unit 15, the data conversion processing unit 16, the display fixed data storage unit 17, the image data generation / storage unit 18, the magnification conversion processing unit 19, the frame buffer 20 and the like are provided.

The molding condition setting storage unit 12 stores various operating condition values input by the keyboard input device 4 and the function key input device 5 in a rewritable form. The operating condition values include, for example, the relationship between the screw position, the screw rotation speed, and the back pressure during the charging stroke, suck back control conditions, and injection speed conditions from the injection start point (position) to the holding pressure switching point (position). And injection pressure condition, 2 from the time when the holding pressure is switched to the end of the holding pressure
Next injection pressure (holding pressure) condition, band heater temperature of each part, mold closing (mold clamping) stroke and speed control condition, mold clamping force, mold opening stroke and speed control condition, eject control condition, automatic product take-out machine control Conditions etc. are mentioned.

The molding process control unit 13 is based on a molding process control program created in advance and setting condition values stored in the molding condition setting storage unit 12, and the sensor group 2 arranged in each unit of the machine. Through the driver group 3 (motor driver, hydraulic cylinder driver, heater driver, etc.) while referring to the measurement information from (position sensor, pressure sensor, temperature sensor, etc.) and the timing information from the clock built in itself. The corresponding drive source is drive-controlled to execute a series of molding steps.

All the actual measurement data of preset monitor items during continuous automatic operation are fetched into the actual measurement value storage section 14 over a predetermined number of continuous shots. The monitor items that are taken in include time monitoring items, position monitoring items, rotation speed monitoring items, speed monitoring items, pressure monitoring items, temperature monitoring items, power monitoring items, and other important items of the molding operation condition setting items described above. Are almost overlapping.

The display control unit 15 is responsive to an instruction to call a display image in a mode desired by the operator by the keyboard input device 4 or the function key input device 5,
Based on a display image creation / control program created in advance, the data conversion processing unit 16, the fixed display data storage unit 17, the image data generation / storage unit 18 and the like are controlled and designated in the image data generation / storage unit 18. Create and store data for the entire display mode image. That is, the display control unit 15 causes the data conversion processing unit 16 to extract the data to be used for displaying the display mode image from the information stored in the molding condition setting storage unit 12 and the measured value storage unit 14 as needed. At the same time, this is converted into image data and sent to the image data generation / storage unit 18. In addition, the display control unit 15 determines the display mode image from the fixed data for a large number of modes, such as characters, symbols, graphic figures, and ruled line data, which are created and stored in the display fixed data storage unit 17 in advance. Data for use in display is extracted, and this is used as the image data generation / storage unit 18
To send. The image data generating / storing unit 18 synthesizes the output data from the data conversion processing unit 16 and the fixed display data storing unit 17 based on the image synthesizing program created in advance to synthesize the characters of the entire designated display mode image, Display data such as symbols, graphic figures, ruled lines, and image data including array information and additional information are created and retained so that they can be rewritten.

FIG. 7 shows the image data generating / storing section 18 described above.
It is a figure which shows typically the image of the mode image data produced and stored by the example, and the example of the figure is operation condition setting image data of an injection stroke. This image data generation / storage unit 1
The image data No. 8 is selectively cut out and extracted by the display control unit 15 and directly sent to the frame buffer 20 or sent to the frame buffer 20 via the magnification conversion processing unit 19. In the initial state in which the operator calls the display image in the desired mode, the image data in the image data generation / storage unit 18 is directly sent to the frame buffer 20 and the frame buffer 20 corresponds to one screen at the reference magnification. Image data is stored. Here, when storing one screen of image data in the frame buffer 20 at the reference magnification,
If all the image data in the image data generating / storing unit 18 fits in the area of one screen of the display device 6 at the standard magnification, the frame buffer 20 stores all the image data in the image data generating / storing unit 18. Is transferred and stored. on the other hand,
When storing one screen of image data in the frame buffer 20 at the standard magnification, if all the image data in the image data generating / storing unit 18 cannot fit within the width of one screen at the standard magnification, the display image is displayed. In the initial state when calling
The display control unit 15 sets the size of the image data in the image data generation / storage unit 18 to the extent of one screen from the upper left reference point O in FIG. 7 (the display screen of the display device 6 shown by the chain double-dashed line in FIG. 7). It is cut out and transferred to the frame buffer 20. Therefore, when the display mode image called by the operator does not fit within one screen at the standard magnification as shown in FIG. 7, the image data within the range surrounded by the two-dot chain line in FIG. The output of the frame buffer 20 is sent to the display device 6 in response to a command from the display control unit 15, and is displayed on the display screen as shown in FIG.
The image data within the range surrounded by the dotted line will be displayed.

In this state, the above-mentioned "function"
When the function key F1 to F8 shown in FIG. 6 is selected by pushing the selection key 9-1 twice, the data for function display of the function key is read out from the fixed display data storage unit 17. Then, this is combined with the mode display image in the image data generation / storage unit 18,
The content of the frame buffer 20 is rewritten and updated, and the mode display image is displayed on the display screen of the display device 6 along with the figures and function characters of the function keys F1 to F8 as shown in FIG. When the function display of the function keys F1 to F8 is performed, the function key function display data is generated and stored in the separate image file area of the image data generation / storage unit 18,
Even if you perform a scroll operation or enlargement / reduction operation described later,
A predetermined portion in the frame buffer 20 is preferentially secured as a dedicated window storage area for function key function display data, and the dedicated window storage area is instructed by the display control unit 15 to generate the image data.
The function key function display data in the separate image file area of the storage unit 18 is directly transferred and rewritten and updated. In the scrolling and enlarging / reducing operations described below, the function key function display associated with this operation will be omitted to simplify the description.

Now, when the function key F7 is pushed to instruct scrolling to the left, for example, in the state where the figures and function characters of the function keys F1 to F8 as shown in FIG. 6 are displayed, The display control unit 15 sets, for example, the image data in the image data generating / storing unit 18 to 1 from the left end of the currently displayed image data.
From the position shifted by 1/16 of the horizontal total length of the screen, the image data on the right side is cut out for one screen, rewritten and updated in the frame buffer 20, and displayed on the display device 6 only for a predetermined time. By repeating the operation once, the image data of the original screen is moved leftward by 1/4 of the horizontal length of one screen. This is function key F5, F6, F8
The same applies to the operation in step 1. Perform one quarter of the horizontal length or the vertical length in four times in one scroll operation to let the operator confirm that scrolling is in progress and to move the image by scrolling. Even so, the operator can easily understand the continuity with the original image.

Further, when the operator pushes the function key F1 to instruct the enlargement of the image in a state where the figures and function characters of the function keys F1 to F8 as shown in FIG. 6 are displayed, the display control is performed. When the currently displayed image is not in the display state of the predetermined maximum magnification, the unit 15 is preset on the display screen as shown in FIG. Only the image data corresponding to the image (A) in the 4-area cutout region S is cut out from the image data in the image data generation / storage unit 18 and transferred to the magnification conversion processing unit 19. The magnification conversion processing unit 19 includes an image data generation / storage unit 18
The image data output from the image data is enlarged and converted based on a preset enlargement ratio to be converted into image data corresponding to one screen, which is output to the frame buffer 20 to rewrite and update its contents. . Therefore, on the display screen of the display device 6, the upper left quarter image (A) in the original image (A, B, C, D) is enlarged to the entire screen as shown in FIG. 8 (b). Is displayed. In this state, when the function key F1 is further pushed to instruct the enlargement of the image, the same processing is performed, and the images (A1, A2, A2, B2) in FIG.
An image (A1) of the upper left quarter portion in (A3, A4) is shown in FIG.
It is enlarged and displayed as shown in (c). In this embodiment,
This image enlargement process is performed only in two or three steps from when the display image has the reference magnification. This is because unlimited enlargement is unnecessary and meaningless in the display device of the molding machine as in the present invention.

On the other hand, when the operator pushes the function key F2 to instruct the reduction of the image from the state of FIG. 8 (c), the display control section 15 causes the area of the image (A1) currently enlarged and displayed. And image data corresponding to the areas of the images (A2, A3, A4) adjacent thereto are cut out from the image data of the image data generation / storage unit 18 and transferred to the magnification conversion processing unit 19. That is, the image data of the currently enlarged image area and the right, lower right, and lower 3 of the currently enlarged image area of the same size as the currently enlarged image area are displayed.
Image data corresponding to one area is extracted and transferred to the magnification conversion processing unit 19. The magnification conversion processing unit 19 performs a reduction conversion process on the image data output from the image data generation / storage unit 18 based on a preset reduction ratio to convert the image data into image data corresponding to one screen. The data is output to the frame buffer 20 and the contents are rewritten and updated. Therefore, on the display screen of the display device 6, FIG.
The images (A1, A2, A3, A4) shown in (b) are displayed. When the function key F2 is further pushed in this state to instruct reduction of the image, the image (A) shown in FIG. 8A is displayed by the same process. Here, in the present embodiment, when the currently displayed image has the reference magnification, it is impossible to reduce the size below this, as described above, and it is meaningless to reduce the characters and the like to make it impossible to determine. Care is taken to avoid becoming.

FIG. 9 is an explanatory diagram showing the above-mentioned image enlargement / reduction processing flow executed in the microcomputer 1. In step ST1 shown in the figure, it is asked whether or not an image is displayed. If YES, the process proceeds to step ST1 and N
If it is O, this flow is ended. In step ST2, it is asked whether or not there is an instruction for enlargement or reduction, and YES.
If so, the process proceeds to step ST2, and if NO, the process jumps to step ST8 to continue the image display at the current magnification. At step ST3, it is asked whether or not the instruction is for reduction, and Y
If it is ES, the process proceeds to step ST4, and if it is NO (if it is an enlargement instruction), the process proceeds to step ST6. In step ST4, it is asked whether or not the magnification of the currently displayed image is larger than the reference magnification. If YES, the process proceeds to step ST5 to reduce the display magnification by one step, and then step ST
Proceed to step 8 to display the image reduced by one step, and click NO.
If so, the process jumps to step ST8 to continue the image display at the reference magnification. On the other hand, in step ST6, it is asked whether or not the magnification of the currently displayed image is smaller than a preset maximum magnification. If YES, the process proceeds to step ST7 to increase the display magnification by one step. The process proceeds to step ST8 to display the image enlarged by one step, and if NO, the process jumps to step ST8 to continue the image display at the maximum magnification.

As described above, in the present embodiment, the image can be enlarged step by step to a size in which the image can be easily seen, and the operating condition set value and the like can be easily confirmed. Further, since the microcomputer automatically cuts out the image data, the operator only has to instruct the enlargement or reduction, so that the enlargement / reduction operation is easy and reliable. Further, since the entire data of one display mode image is collectively stored in the image data generating / storing unit, the amount of data to be handled is larger than that when one display mode image is divided into a plurality of screen data. Is small, and since the cutout area of the image data is constant and the enlargement / reduction ratio is also constant,
It is possible to provide a system in which arithmetic conversion processing is easy (construction of a program is easy) and there is no significant burden in terms of software and hardware.

[0023]

As described above, according to the present invention, it is possible to enlarge a part of an image to a size in which it is easy to see, the enlargement / reduction operation is easy and reliable, and the hardware is used in terms of software. A display screen control method for a molding machine that does not require much burden can be realized, and its value is great.
