Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding machine such as an injection molding machine or a die casting machine capable of displaying various images on a display screen of a display device, and particularly to a molding machine having a user-friendly learning display function. It is about machines.

[0002]

2. Description of the Related Art In a molding machine such as an injection molding machine,
On the display screen of the display device attached to the machine (injection molding machine), select an image for each mode type such as injection weighing related display mode, mold opening / closing related display mode, monitor related display mode, graph related display mode, etc. I can display it. Then, for example, by selectively displaying the desired operating condition setting image, the operation condition setting / changing operation is performed, or by selectively displaying the desired graph image, the set value and the measured value are compared and visually confirmed.・ It is possible to consider things.

By the way, in recent years, molded products are required to be precise and highly accurate, and in order to meet such demands, machines are equipped with multiple functions. And in order to support various molded products,
Various kinds of operation modes are prepared, and a desired one of them can be selected, or a large number of set values can be set / changed so that fine setting and fine adjustment can be performed. Therefore, the types of images displayed are increasing, and the number of setting value items displayed in one image is increasing.

On the other hand, as a display device attached to a machine, a liquid crystal display device having a display screen of 10.4 inches to 12 inches, which is relatively large and has a good visibility as compared with the conventional one, has been adopted in recent years. ing. However, even if such a liquid crystal display device having a relatively large display screen is adopted, the number of items that can be displayed in one image and the display resolution of a graph are naturally limited. Therefore, it has been unavoidable that the number of images to be displayed is increased and the number of items displayed in one image is also increased in order to cope with the multi-functionalization.

[0005]

As described above, in a molding machine such as an injection molding machine, the number of images to be displayed is increasing, so that the number of key operations until the desired image is displayed is increased. However, there is a problem that the image switching operation is complicated. Also, when switching to the display state of a certain operating condition setting image, the setting / changing cursor is always positioned at the setting item at the predetermined position (for example, the upper left position) in the newly displayed operating condition setting image. Therefore, in order to set / change the numerical value other than the setting item for which this setting / changing cursor is set, the desired one is visually searched out from the many setting items in the operating condition setting image, and here Since it is necessary to set and change the numerical value after setting the setting / changing cursor, it has been pointed out that the task of visually locating it is troublesome and quick setting / changing operations cannot be performed.
That is, in the display form of the conventional molding machine, there is a problem that the operation is complicated, a quick operation cannot be performed, and an operation error is likely to occur.

The present invention has been made in view of the above points,
Its purpose is to enable quick access to frequently used images and quick setting / changing operations of frequently used setting items. Generally, the display should be easy to operate or easy to see. The object is to provide a user-friendly molding machine that can be used.

[0007]

In order to achieve the above object, in a typical invention according to the present invention, at least one image is displayed for each display mode type such as a graph mode and a monitor mode. In addition, a mode selection key corresponding to each mode type is provided, and by selecting and operating one of the mode selection keys, an image of the selected mode type is displayed on the display screen of the display device provided in the molding machine. In the molding machine in which one of the selected mode types is displayed, the molding machine has an image selection key for selecting an image included in the selected mode type, and For each mode type, the most frequently displayed image within the predetermined period or the most recently displayed image is operated next time by operating the mode selection key of the corresponding corresponding mode type. Sometimes, with a means for displaying automatically the display device of the display screen, a configuration.

Also, mode selection keys 6-1a to 6-1h.
When any of the images is pushed to call an image, an image selection key for switching and calling another image included in the same display mode type is displayed in each image. For example, when the mode selection key 6-1a of the "injection weighing" display mode is pushed in the initial state, the "injection weighing setting" image as shown in FIG. 7 is displayed, and in the lower side of this image, in order from the left, A key for selecting “injection weighing”, a key for selecting “injection graph”, and a key for selecting “metering graph” are displayed. Then, when the "injection graph" selection key is pushed in the state shown in FIG. 7, the "injection graph" image is switched and displayed.
Further, for example, when the mode selection key 6-1f in the "graph" display mode is pushed in the initial state, an "injection graph" image as shown in FIG. 5 is displayed, and in the lower side of this image, from left to right, "Injection graph" selection key, "Weighing graph" selection key, "1 cycle graph" selection key, "1 cycle logic" selection key, "Item selection"

The "F key return" selection key is displayed, and in this state, for example, when the "semi-fixed value 1" selection key is pushed, the "semi-fixed value 1" image is switched and displayed. (FIG. 12 shows the display state of this “semi-fixed value 1” image).

Next, the operation of this embodiment will be described. Here, first, an example will be described of an operation of adjusting the setting of the cooling timer to an optimum value while molding.

The cooling timer is a timer that waits for the resin to cool and solidify in the mold after the injection process (primary injection process and subsequent pressure-holding process) for injecting and filling the mold with resin. When the cooling timer is up, the mold opening is started. In addition, in the injection molding machine, during the cooling timer operation, the measuring operation of kneading and plasticizing the resin pellets is performed, and the end of this measuring operation and the end of the cooling and solidification of the resin are the same timing. If so, the cycle time of molding becomes the minimum, and if such a cooling and solidifying time is used as the value of the cooling timer, it becomes an ideal value. However,
In the metering operation, the time until the completion of the metering operation generally varies due to the difference in the density of resin pellets and the variation in kneading / plasticization.Therefore, normally, the cooling timer value is I am trying to set a long time with a margin compared to the time to complete.

When the cooling timer is adjusted as described above, the above-mentioned "one cycle graph" image is prepared as an image capable of temporally confirming the end of the weighing operation and the start of the mold opening operation. ing. In the initial state of the display form, in order to call this "1 cycle graph" image, first, the mode selection key 6-1f in the "graph" display mode is pushed to display the "injection graph" image as shown in FIG. Is displayed, and then, by pushing (touching) the “1 cycle graph” selection key in the “injection graph” image of FIG. 5 with a finger or the like, the “1 cycle graph” image as shown in FIG. 6 is displayed. Is displayed. In the “1 cycle graph” image of FIG. 6, the horizontal axis represents cycle time, the vertical axis represents speed, pressure, and rotation speed, and the measurement completion timing is the fall of the rotation speed (screw rotation speed) The opening start timing can be confirmed by the rise of the mold opening / closing speed in the positive direction, and the time from the completion of the weighing operation to the start of the mold opening can be confirmed at a glance.

After viewing the "1 cycle graph" image in FIG. 6, in order to adjust the cooling timer, the mode selection key 6-1a in the "injection metering" display mode is pushed. Mode selection key 6-1 in the initial state of the display form
When “a” is pushed, an “injection weighing setting” image as shown in FIG. 7 is displayed. At this time, the setting cursor 21 in the "injection weighing setting" image is positioned in the setting item column on the left side of the top row, and the numerical value of the item where the setting cursor 21 is positioned is set or changed. It means that it is possible. In the “injection measurement setting” image of FIG. 7, when the “cooling timer” setting item field is searched for and pushed (touched), as shown in FIG. 8, the setting cursor 21 is set in the “cooling timer” setting item field. Is displayed. Then, in this state, the value of the cooling timer is changed by changing the numerical value in the setting item column of the "cooling timer" with the ten keys 6-3.

The above is the operation of adjusting the value of the cooling timer with reference to the image of "1 cycle graph". When the operation procedures are arranged, the mode selection key 6-1f is pushed (touched), "1 cycle". The procedure is to push (touch) the "graph" selection key, push (touch) the mode selection key 6-1a, push (touch) the "cooling timer" setting item field, and set / change the cooling timer value. Thus, many operations are required. In the past, such a troublesome procedure was required every time when the value of the cooling timer was adjusted, whereas in the present embodiment, the number of operations when adjusting the cooling timer after the second time is
I am trying to reduce it. This will be described below.

That is, when the "1 cycle graph" image is displayed, the operation for displaying the "1 cycle graph" image first is the same as before, but the mode selection key for the "graph" display mode after the second time is displayed. When 6-1f is pushed, the display processing unit 15, which remembers that the "1 cycle graph" image was displayed last time, immediately displays the "1 cycle graph" image as shown in FIG.
In the “1 cycle graph” image of FIG. 9, the image selection key (image selection function key) displayed on the lower side of the image has the “1 cycle graph” selection key arranged at the left end. "Injection graph" selection key, "Weighing graph" selection key, "1 cycle logic" selection key, "Item selection" selection key are arranged in order on the right, and the latest image selection In the order of the images
The image selection keys are rearranged.

When the value of the cooling timer is adjusted in the "injection weighing setting" image, the operation when the cooling timer is adjusted first is the same as before, but after the second and subsequent times, "injection weighing" is performed. When the mode selection key 6-1a of the display mode is pushed to call the "injection measurement setting" image, the display processing unit 15 that remembers that the item "cooling timer" was set / changed last time is displayed. As shown in FIG. 10, the “injection weighing setting” image in which the setting cursor 21 is positioned in the “cooling timer” setting item column is displayed. Therefore, it becomes possible to immediately adjust the value of the cooling timer without visually searching for the item column of "cooling timer".

When the operation procedures for adjusting the cooling timer for the second time and thereafter are arranged, the mode selection key 6-1f is shown.
, Push the mode selection key 6-1a,
The procedure is to set / change the value of the cooling timer so that the number of operations can be reduced. In other words, conventionally, it is necessary to perform the operation 4 times before the setting / changing of the cooling timer even after the second time, but in the present embodiment, the operation before the setting / changing of the cooling timer is performed after the second time. It only needs to be done twice. Further, when the “injection measurement setting” image is displayed, the setting cursor 21 is positioned in the setting item column of the “cooling timer”, so that the value of the cooling timer can be immediately changed, and the “cooling timer” can be changed. It saves you the trouble of searching for the item column of ", and you can set and change it quickly.
Moreover, the risk of erroneous operation is reduced.

In the above operation example of the display processing, one mode selection key Nx is operated to display one image having a mode type corresponding to the selected mode selection key Nx, and the selected mode type is selected. When the image selection key Mx for selecting another image is operated, and the same mode selection key Nx is operated next time, the image corresponding to the most recently operated image selection key Mx is given priority. However, the image selection key Mx is preferentially displayed at the left end. However, in the image group corresponding to each image selection key in one display mode type, a predetermined period (for example, 1 The image corresponding to the one with the highest operation frequency within (day) is prioritized and displayed when the same mode selection key corresponding to this display mode type is operated.
A plurality of image selection keys may be arranged and displayed in descending order of display frequency. Again, setting cursor 2
When the image containing 1 is called, the setting cursor is automatically positioned at the position of the most recently operated item, but the setting / changing is the most within a predetermined period (for example, one day). The setting cursor may be automatically positioned at the position of the item whose operation frequency is high.

Next, an operation example of a display process will be described in which an item for which no setting is made in the operation condition setting image is erased (masked) on the image. . Here, the “injection measurement setting” image is taken as an example of the operation condition setting image. The "injection measurement setting" image shown in FIG. 7 is displayed by the operation as described above.

In the "injection measurement setting" image shown in FIG. 7, many items (position, speed, pressure, timer (time), stroke (width) regarding the injection process (primary injection process and pressure-holding process) and the metering process are set. ), Rotation speed, etc.) can be set. Regarding the primary injection stroke and the pressure holding stroke, the number of stages can be set in another image, and the operator presets the number of stages which is considered necessary. In the example shown in FIG. 7, the primary injection stroke is 5
The stages (1st to 5th speeds) and the pressure-holding process are preset to 4 stages (secondary pressure to 5th pressure). However, if the conditions of the injection stroke are adjusted while actually performing a test shot, an unnecessary number of stages may occur. In such a case, the set value of the stage for which the set value is not input at all, or the set value of the stage for which the set value is not changed even if the "Injection weighing setting" image is called multiple times is displayed. If you continue to, the appearance will be complicated and it may cause an erroneous operation.

Therefore, in the present embodiment, when a certain operating condition setting image is called and displayed a predetermined number of times, items that have not been operated during this period are sequentially deleted from the image, and a simple and neat image display is provided. I am trying to become. Specifically, for example, even if the “injection measurement setting” image is called and displayed three times, the fifth speed item of the primary injection stroke and the third to fifth pressure items of the pressure holding stroke are set once. When the change operation is not performed, the display processing unit 15 displays the items of the 5th speed of the primary injection stroke and 3 of the holding pressure stroke.
It is judged that the display of items of secondary pressure to fifth pressure is unnecessary from the next time onward,
At the next time of displaying the “injection measurement setting” image, as shown in FIG. 11, the items of the fifth speed of the primary injection stroke and the items of the tertiary pressure to the fifth pressure of the holding pressure stroke are erased (masked). Display the “Injection weighing setting” image.

A display return mark 22 for returning the erased item to the return display is displayed in the vicinity of the erased item.
It is possible to return to the display state as shown in FIG. 7 by pushing (touching) 2.

In this example, when a certain operating condition setting image is called up and displayed a predetermined number of times, the item which has not been operated during this time is displayed next time when the same operating condition setting image is called up and displayed. However, the item was not set when the original driving condition setting image was called, and when this driving condition setting image was called and displayed a predetermined number of times, it was never operated. Only the items may be automatically erased when the same operation condition setting image is displayed next time.

The item to be deleted may be set by combining the number of times the operating condition setting image is called and the number of times of setting / changing operations for each item.

Next, in the operating condition setting image displayed in the form of a list, the frequently operated items are prioritized and displayed in a priority arrangement so that they are easy to see and easy to set and change. Further, an operation example of the display process will be described in which items that are determined not to be displayed are automatically deleted. The list-type operating condition setting image referred to in the present invention refers to an image in which a plurality of setting value items are displayed vertically or horizontally on a display screen.

There are a number of items that can be set / changed in the types of operating condition setting images in the injection molding machine, but most of the items do not change the initial setting values and are frequently changed. There are one or two operating condition setting images for setting / changing. A semi-fixed value setting image is one of such operating condition setting images.

Now, in the initial state, "maintenance"
When the mode selection key 6-1h in the display mode is pushed, an "inspection" image (not shown) is displayed as described above, and the "F key next" selection key in this image is pushed (touched) twice. By doing so, the "semi-fixed value 1" selection keys and the like are displayed, and then the "semi-fixed value 1" selection key is pushed (touched) to display the "semi-fixed value 1 ( Semi-fixed value setting 1) ”image is displayed.
In the “semi-fixed value 1 (semi-fixed value setting 1)” image, the setting cursor 21 is automatically positioned at the uppermost item in the left column. In the "semi-fixed value 1 (semi-fixed value setting 1)" image of FIG. 12, for example, touch the setting field of "mold thickness mold opening" third from the top in the left column and position the setting cursor 21 there. "Mold thickness mold open"
It is assumed that the setting of is changed from 100% to 90%.

Next, when the mode selection key 6-1h is pushed in the display state of an appropriate image of another mode type, the image previously displayed in the "maintenance" display mode is displayed as "semi-fixed value 1 (semi-fixed value 1 The display processing unit 15 that stores the “setting 1)” image immediately displays the “semi-fixed value 1 (semi-fixed value setting 1)” image as illustrated in FIG. "Semi-fixed value 1 (semi-fixed value setting 1)" in FIG. 13
In the image, the item “mold thickness mold open” for which the setting / changing operation was performed last time is rearranged and displayed in the uppermost row in the left column. In this way, the setting and change of the "mold thickness die opening" after the second time is the item in the top row of the left column, so there is no need to search for it, and in this case, in the top row of the left column. Since the setting cursor 21 is always positioned on the item, the setting / change of “mold thickness mold opening” can be performed quickly and surely and without fear of erroneous operation. In addition, "semi-fixed value 1" in FIG.
In the "(semi-fixed value setting 1)" image, the image selection keys displayed on the lower side of the image are rearranged so that the "semi-fixed value 1" selection key is at the top.

Further, in the "semi-fixed value 1 (semi-fixed value setting 1)" image in FIG. 13, for example, the second "injection start timing" setting field from the right column is touched, and the setting cursor 21 is set here. It is assumed that the setting of “injection start timing” is changed from 0.20 s to 0.15 s in the state where is positioned. Then, when the mode selection key 6-1h is pushed in the display state of an appropriate image of another mode type, a "semi-fixed value 1 (semi-fixed value setting 1)" image as shown in FIG. 14 is immediately displayed. To be done. In the “semi-fixed value 1 (semi-fixed value setting 1)” image of FIG. 14, the “injection start timing” when the setting / changing operation was performed last time is performed.
The items of are sorted and displayed in the uppermost row in the right column.

Furthermore, in the "semi-fixed value 1 (semi-fixed value setting 1)" image of FIG.
Suppose you changed from 0% to 95%. Then, when the mode selection key 6-1h is pushed in the display state of an appropriate image of another mode type, a "semi-fixed value 1 (semi-fixed value setting 1)" image as shown in FIG. 15 is immediately displayed. To be done. “Semi-fixed value 1 (semi-fixed value setting 1)” in FIG. 15
In the image, the set / changed items are only the items of “mold thickness die opening” and “injection start timing”, and the display processing unit 15 that determines that the display of other items is unnecessary,
Only two items, "mold thickness mold opening" and "injection start timing" are displayed. By doing so, a neat image structure in which only two items are displayed is displayed, and it is possible to perform speedy setting / change without erroneous operation. In FIG. 15 as well, a display return mark 22 for returning and displaying the erased item is displayed, and the display return mark 2 is displayed.
By pushing (touching) 2, it is possible to return to the display state as shown in FIG.

If the values of a plurality of items are changed in the vertical column of items, the item changed most recently is set to the top row, and from the next newest item,
The items having the highest change operation frequency within a predetermined period (for example, one day) may be placed in the uppermost row, and the items having the next highest change operation frequency may be sequentially placed below. It is also possible to do so (in the case of the same frequency, the most recently operated item should be on the upper side). Furthermore, although the operating condition setting image displayed in the form of a list has a vertical arrangement of items, when the items have a horizontal arrangement, the item with the highest priority should be displayed on the leftmost side. You can do this.

FIG. 16 corresponds to the one having the highest display frequency within a predetermined period for each display mode type when the mode selection keys 6-1a to 6-1h of the input device 6 are pushed. An image display order management table (for image display order management) in the display processing unit 15 when performing control to display images with priority and to arrange and display a plurality of image selection keys in descending order of display frequency It is a figure which shows the content of memory.

The image display order management table is provided for each mode type of each display (each mode selection key 6-1a to 6-1h), and is associated with the image number of each image in the mode type within a predetermined period. A display counter unit that counts the number of times of display in, a time storage unit that stores the latest display time (here, it is simplified but includes month and day), and a rank storage unit that stores the display priority order are provided. Has been. In the initial state, the contents of the display counter section are all "0".
The order storage unit stores the numbers of the predetermined image arrangement order (for example, the arrangement order shown in FIG. 4) set as an initial value. When an image in this mode type is selected and displayed, the content of the display counter section for that image number is counted up (+1), and at the same time, its display time is stored in the time storage section. Further, referring to the contents of the display counter unit, the display order of the images is rearranged in the order of increasing counter value, and the images having the counter value of “0” are arranged in the order of initial value. The process of updating the contents is performed. At this time, when there are a plurality of images having the same counter value, priority is given to the latest time order. The contents of the image display order management table are cleared to the initial state after a lapse of a predetermined period.

When the mode selection key corresponding to the image display order management table is pushed, the image with the highest priority is displayed and the image selection key is pressed according to the contents of the rearranged order storage section. Display side by side. The flowchart of FIG. 17 shows an outline of such control processing.

In FIG. 18, when a certain list-type operation condition setting image is displayed, in this operation condition setting image, the item display is arranged in the order of the setting items that are most frequently set / changed within a predetermined period. Item display order management in the display processing unit 15 in the case of performing replacement and performing control to delete an item for which setting / modifying operation has not been performed when this operation condition setting image is called multiple times It is a figure which shows the content of the table (memory for item display order management).
Note that, for simplification of description, it is assumed that the operating condition setting image in the form of a list is in the form of a list having only one column.

The item display order management table is provided for each operating condition setting image in the form of a list, and is associated with the item number of each setting item in the operating condition setting image, and is set / changed (input) within a predetermined period. Access counter section that counts the number of times of changes), a time storage section that stores the latest setting / change time (including month and day although it is simplified here), and a priority storage that stores the display priority order. And a section are provided. In the initial state, the contents of the access counter section are all "0", and the order storage section stores the numbers of the arrangement order of the predetermined setting items as the initial values. When the operating condition setting image corresponding to this item display order management table is called and the value of a certain item in this operating condition setting image is set / changed, the content of the access counter part of the item number is counted up (+1).
At the same time, the set / changed time is stored in the time storage unit. Further, referring to the contents of the access counter section, the display order of the setting items is rearranged in descending order of the counter value, and the items having the counter value of “0” are arranged in the order of the initial value so that the order storage section is arranged. Update the contents of. At this time, when there are a plurality of items having the same counter value, priority is given to the order of the latest time. In addition,
The contents of the item display order management table are cleared to the initial state after a lapse of a predetermined period.

Then, when the operation condition setting image in the list form corresponding to the display order management table is called from the display state of other images, the operation in the list form in which the setting items are rearranged in the descending order of priority. In addition to displaying the condition setting image, even if this operating condition setting image is displayed a predetermined number of times (for example, three times), items that have not been set / changed are not displayed, and instead a display return mark is displayed. To do. The flowchart of FIG. 19 shows an outline of such control processing.

In the ranking by the counter value of the access counter section, considering the factor of time, even if the counter value is large, the set / changed date is old (for example, 12 hours or more). For those that have passed, etc.), the priority may be lowered (this is shown in FIG.
The same applies to the ranking by the counter value of the display counter unit of 6).

Here, the changing display form by the learning function described above is automatically changed by the function of the display processing unit 15 to the initial state when there is no operation for a certain period (for example, 24 hours). Although it is designed to return to the setting state, an initial state return key (not shown) for returning the display form to the initial setting state is provided, and by pushing this key, all displays are in the initial setting state. It is also possible to return to.
