Description

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 and 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 along with this, the above-mentioned setting mode image and monitor mode image are displayed. The number of set values and actual measurement data is increasing, and this trend 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 in that it is difficult to see what the set value is because similar numbers 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 with 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 memory capacity increase. On the other hand, as seen in word processors etc., by pushing the scroll key,
If the display image is moved by one line pitch or one character pitch, the transition of the screen will be messy, and it will be a loss of time for the operator who is in charge of monitoring many machines on site. .. However, if you push the scroll key to move the display image a large amount at a stretch, the relationship between the next data (out-of-screen data) and the data before scrolling when enlarged display etc. There is a problem that it is difficult to grasp.

The present invention has been made in view of the above points,
The purpose is to make the scroll amount of the image appropriate on the monitor display device of the molding machine so that the relationship with the previous data can be easily grasped even if scrolling is performed. It is to realize a display screen control method for a molding machine that does not require much load.

[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 method for controlling the display screen of the molding machine, the movement of the image in the designated direction is made 1/8 or more of the horizontal or vertical total length of the display screen and 1 / by the scroll command issued by the operator.
The predetermined amount of 2 or less is performed, and the predetermined amount of image movement is executed in a plurality of divided steps.

[0007]

When the operator calls a desired display mode image, the display data such as characters, symbols, ruled lines, etc. of the entire specified display mode image are stored in the image data generating / storing section in the microcomputer, and 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 this state, when the operator pushes the scroll instruction key to the left, for example, the display control unit displays the image data in the image data generation / storage unit,
From the left edge of the currently displayed image data, a position shifted by 1/16 of the horizontal length of one screen, cut out the image data on the right for one screen, rewrite this in the frame buffer and update it, and display it only for a predetermined time The image is displayed on the device and this procedure is repeated four times to move the image data of the original screen to the left by ¼ of the horizontal length of the screen. This also applies to the scroll operation in the other direction, and a single scroll operation is used to perform a movement of 1/4 of the horizontal length or the vertical length of the screen in four steps.

As described above, since the image is moved by the amount of movement less than 1/2 of the horizontal or vertical total length of the screen by one scroll operation, at least half or more of the image before the movement remains. The relation between the data before the movement and the data after the movement can be easily grasped, and since one scroll is performed in a time division manner, the operator can further easily grasp the continuity with the original image. Further, since the amount of movement of the image by one scroll is not less than ⅛ of the horizontal length or the vertical length of the screen, it is convenient for the operator who monitors the machine installed on the site. 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. The system can be a system that requires only a small amount of resources and does not place a heavy burden on software or hardware.

Thus, in the state shown in FIG. 5, the function keys F1 to F7 function as selection input keys for the functions displayed in 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 and F2 and F5 to F8 function as selection input keys for the functions displayed in 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 FIG. 5 and FIG. 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 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 with 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, 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.

In the molding condition setting storage unit 12, various operating condition values input by the keyboard input device 4 and the function key input device 5 are stored in a rewritable form. The operating condition values include, for example, the relationship between the screw position and the screw rotation speed and the back pressure during the charging process, 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) conditions, band heater temperature of each part, mold closing (mold clamping) stroke and speed control conditions, mold clamping force, mold opening stroke and speed control conditions, eject control conditions, control of automatic product ejector 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 measurement information from (position sensor, pressure sensor, temperature sensor, etc.) and timing information from a 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 consecutive 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 an 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. Creates and stores data for the entire displayed 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 or 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 uses the fixed data for a large number of mode images, which are created and stored in advance in the display fixed data storage unit 17, such as characters, symbols, graphic figures, and ruled line data, to display the display mode image of the display mode image. Data to be used for display is extracted and 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 synthesis program created in advance to synthesize the characters of the entire designated display mode image, Display data such as symbols, graphic figures, and ruled lines, and image data including arrangement information and additional information are created and retained so that they can be rewritten.

FIG. 7 shows the image data generating / storing unit 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 generating / storing unit 18 is directly sent to the frame buffer 20, and one frame worth of image is stored in the frame buffer 20 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,
When 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 generating / storing unit 18 to the extent of one screen from the upper left reference point O in FIG. 7 (for the display screen of the display device 6 indicated 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 reference 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 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 contents of the frame buffer 20 are 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 controller 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 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, converted into image data corresponding to one screen, and is output to the frame buffer 20 to rewrite and update the 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 to enlarge the image, the same process 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 FIG. In this example,
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. 8C, the display control unit 15 causes the area of the image (A1) which is 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 image area currently being enlarged and displayed, and the right, lower right, and lower 3 of the image area currently being enlarged and displayed with the same size as the image area currently being enlarged and 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 its 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 impossible to discriminate by reducing the characters and the like insignificantly. Care is taken to avoid becoming.

If the function key F7 is pushed to instruct scrolling to the left when the graphics 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 generation / storage 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. The image data of the original screen is moved to the left by ¼ of the entire horizontal length of the screen by repeating the above process. FIG. 9 is a diagram showing how the image is scrolled to the left, from the state of FIG. 9A to that of FIG.
After the states of (c) and (d), the image is moved to the state of (e) in the figure by one scroll operation. That is, the image (E,
(F, G, H) becomes the image (F, G, H, I) shown in (e) of FIG. 9 after the scroll operation. This scroll operation is performed by pressing the function keys F5, F6, F8 in the other direction.
The same applies to the operation in step 1. Perform one scroll operation to move the horizontal length or the vertical length by 1/4 in four steps to let the operator confirm that scrolling is in progress and move the image by scrolling. Even so, the operator can easily understand the continuity with the original image.

Here, in the present embodiment, one horizontal scroll operation or one-fourth of the vertical full length image movement is performed. However, the movement amount of one scroll operation is the horizontal movement of the screen. It is desirable that the total length or vertical length is 1/8 or more and 1/2 or less, and if the amount of movement in one scroll operation is 1/8 or more of the horizontal or vertical total length of the screen,
If the screen transition is not messy for the operator and the amount of movement in one scroll operation is less than 1/2 of the horizontal or vertical total length of the screen, at least half of the image before movement remains. Therefore, it becomes easy to grasp the relationship between the data before the movement and the data after the movement.
Note that how many times each scroll is time-divided is arbitrary.

FIG. 10 is an explanatory diagram showing a flow of the above-described image scrolling process 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 ST2.
If NO, this flow ends. In step ST2,
Whether or not a scroll instruction is given, if YES, the process proceeds to step ST3, and if NO, the process jumps to step ST5 to continue the image display at the current position. In step ST3, it is asked whether or not the image currently displayed in the scroll-instructed direction is in a state where scrolling is possible. If YES, the process proceeds to step ST4 to perform scroll processing, and then to step ST5. The image scrolled by is displayed. If NO, step ST5.
Jump to and continue displaying the image at the current position.

As described above, in the present embodiment, one horizontal scroll operation or half the vertical full length of the screen is performed by one scroll operation.
Since the image is moved by the following movement amount, at least half or more of the image before the movement remains, which makes it easy to grasp the relationship between the data before the movement and the data after the movement, and one scroll Is performed in a time-division manner, it becomes easier for the operator to grasp the continuity with the original image. Also, since the amount of movement of the image by one scroll is 1/8 or more of the horizontal or vertical total length of the screen, the amount of movement of the image is relatively large compared to a word processor, etc., and the transition of the image is mellow. It is not awkward and convenient for operators who monitor machines installed in the field. In addition, since the entire image data of one display mode image is collectively stored in the image data generation / storage unit,
Compared to the case where one display mode image is divided into a plurality of screen data, the amount of data to be handled is small, and the system can be a system with less burden on software and hardware.

[0024]

As described above, according to the present invention, the scroll amount of an image is made appropriate on the monitor display device of the molding machine, and the relation with the previous data can be easily grasped even when scrolling is performed. In addition, it is possible to realize a display screen control method for a molding machine that does not impose a heavy burden on software and hardware, and its value is great.
