In this case, the image data Dv can be displayed by putting a check mark in the check box, and the display of the image data Dv can be masked by removing the check mark.
[0020]
By the way, the molding condition memo data Dm and the image data Dv to be displayed on the molding condition memo display section Vm are stored in the storage medium 28 as an external memory together with the molding condition data (file data) Ds. When molding is performed, target molding condition data Ds, molding condition memo data Dm and image data Dv corresponding to the molding condition data Ds are read from the storage medium 28 in advance, and the internal memory 25 built in the controller 20 stores the data. Reads data into the data storage area. Hereinafter, the reading process will be described according to the flowchart shown in FIG. 4 with reference to FIGS.
[0021]
First, the storage medium 28 is set in the drive unit 27 in the controller 20. This storage medium 28 stores a large number of molding condition data Ds... With file names. Since the molding condition data Ds is normally created in a text format, each molding condition data Ds ... includes corresponding molding condition memo data Dm ... created in a text format. If there is image data Dv ... corresponding to each molding condition data Ds ..., the same file name as the corresponding molding condition data Ds ... is used, and ".JPEG" or ".BMP" is used for the extension part. ”Is stored in the same folder as the corresponding molding condition data Ds. “.JPEG” is used for image data Dv in JPEG format, and “.BMP” is used for image data Dv in BMP format.
[0022]
On the other hand, the condition switching screen switching key K7 displayed on the display 2 of the controller 20 is touched (step S1), and the condition switching screen Vba shown in FIG. 5 is displayed on the display 2 (step S2). This condition switching screen Vba has an internal media display field 55 for displaying a list of file names of all molding condition data Ds... Stored in the internal memory 25 of the controller 20 in the upper half, and in the lower half. And an external media display field 56 for displaying a list of file names of all molding condition data Ds... Stored in the storage medium 28. Further, on the right side of the internal media display field 55, there are a read button 57a, a save button 57b and a delete button 57c used for the internal media display field 55, and on the right side of the external media display field 56, this external media display field 56 A read button 58a, a save button 58b, and a delete button 58c are used for 56. Thus, if the save buttons 57b and 58b are touched, the molding condition data Ds and related image data Dv (folder) can be saved, and if the delete buttons 57c and 58c are touched, the molding condition data Ds. And related image data Dv (folder) can be deleted (steps S3, S4, S5).
[0023]
Then, when reading the molding condition data Ds, the read button 58a in the external media display field 56 is touched (steps S3 and S6). Thereby, the reading initial screen Vbb shown in FIG. 6 is displayed on the display 2 (step S7). The initial screen Vbb includes a current molding condition display unit 61 that displays the current molding conditions, a media display field 62 that displays a list of file names of all molding condition data Ds... Stored in the storage medium 28, and a preview display. A preview screen 63 for displaying the file name, a file name display unit 64 for displaying the selected file name, a preview selection key 65, a read key 66, an EXIT key 67, and the like.
[0024]
Next, the molding condition data Ds to be read is selected from the media display column 62 of the read initial screen Vbb (step S8). In this case, the file name can be selected by touching. In the embodiment, as shown in FIG. 7, an example is given in which a check mark is entered in the corresponding check box by touching the file name, but the display of the selected file name may be reversed in black and white. As a result, the file name is displayed on the file name display unit 64.
[0025]
In addition, it is possible to select whether the selected molding condition data Ds is directly read or read after being previewed (step S9). In the case of direct reading, by touching the read key 66, the reading process for the data storage area of the internal memory 25 is immediately performed (step S13). As a result, the molding condition data that has already been read, that is, the molding condition data displayed in the current molding condition display unit 61 is rewritten.
[0026]
On the other hand, when preview display is performed, the preview selection key 65 is touched (step S10). As a result, the folder including the molding condition data Ds related to the selected file name and the related image data Dv is written into the temporary storage area in the internal memory 25 and a preview display is performed (step S11). FIG. 7 shows the read display screen Vbc after the preview selection key 65 is touched. The preview display only needs to confirm the contents of the molding condition data Ds. Therefore, the preview screen 63 includes only data for confirming the contents of the molding condition data Ds among the individual data constituting the molding condition data Ds. Is displayed, that is, only a part of the data in the molding condition data Ds is displayed. The data to be displayed for preview can be processed as necessary. The preview display also displays the molding condition memo data Dm added to the molding condition data Ds. Further, since image data Dv such as drawings and photographs related to the molding condition data Ds is also stored in the folder of the molding condition data Ds, a separate window display screen 68 as shown in FIG. Thus, the image data Dv is displayed.
[0027]
Then, the operator confirms the contents displayed in the preview, and touches the read key 66 if it can be confirmed that the molding condition data Ds is the target (steps S12 and S13). Thereby, the reading process (rewriting process) from the temporary storage area of the internal memory 25 to the data storage area is performed. On the other hand, the content displayed in the preview is confirmed, and if it is not the target molding condition data Ds, the process returns to the above-described step S8 again, and other molding condition data is read from the media display column 62 of the read initial screen Vbb. select. Thereby, the same confirmation can be performed according to the above-described procedure for the reselected molding condition data Ds (steps S12, S8). Thus, the reading process of the molding condition data Ds including the molding condition memo data Dm from the storage medium 28 to the control 20 side and the related image data Dv is completed.
[0028]
Next, a data display method according to the present embodiment using the setup screen Va will be described according to the flowchart shown in FIG. 9 with reference to FIGS. In the flowchart shown in FIG. 9, steps S21 and S22 indicate the reading process described above.
[0029]
First, the setup screen Va shown in FIG. 1 is displayed by touching the setup screen switching key K8. Since the setup screen Va has the molding condition memo display portion Vm described above, the display processing of the image data Dv and the molding condition memo data Dm is performed on the molding condition memo display portion Vm by the data display method according to the present embodiment. Is called.
[0030]
By the way, in the data display method according to the present embodiment, two types of background Bs for displaying the molding condition memo data (text data) Dm are set in advance. That is, a first screen (first layer) V1 that is entirely transparent and a second screen (second layer) V2 that is at least partially non-transparent are set. FIG. 8 shows the imaged first screen V1 and second screen V2. When the first screen V1 is set for the background Bs, the entire surface becomes transparent. On the other hand, when the second screen V2 is set for the background Bs, the entire surface is white and non-transparent, and the molding condition memo data The part of the ruled line where Dm is not displayed becomes transparent by the slit-shaped part Es. Also, a dummy screen (third layer) V3 is set in which the entire surface selected to be the same color as the second screen V2 is white and non-transparent.
[0031]
In the display process, first, the presence / absence of the image data Dv is determined from the folder related to the molding condition data Ds stored in the data storage area of the internal memory 25 (step S23). At this time, if there is no image data Dv, the second screen V2 is used, the background of the molding condition memo data Dm is set to white, and the dummy screen V3 is used. Is overlaid with the molding condition memo data Dm with the background Bs (steps S24, S25, S26). This state is indicated by an arrow F1 in FIG. Thus, a dummy screen V3 having the same color as that of the second screen V2 is displayed on the slit-shaped portion Es ... of the second screen V2. Therefore, since the molding condition memo data Dm is displayed in a normal state on a white background, the display quality when there is no image data Dv can be further improved.
[0032]
On the other hand, when the presence or absence of the image data Dv is determined (step S23), if the image data Dv exists, the following display processing is performed. First, when a check mark is put in the check box in the image data display selection unit 53 and selection is made to display the image data Dv (step S27), both the molding condition memo data Dm and the image data Dv are displayed. In this case, the first screen V1 is used to set the background of the molding condition memo data Dm to be transparent, and when displaying, the molding condition memo with the first screen V1 as the background Bs is displayed for the image data Dv. The data Dm is superimposed and displayed (steps S28, S29, S26). This state is indicated by an arrow F2 in FIG. Accordingly, the image data Dv and the molding condition memo data Dm are displayed in an overlapping state as shown in FIG. 1, and both are displayed in the maximum size on the molding condition memo display portion Vm. Become.
[0033]
By the way, when the image data Dv and the molding condition memo data Dm are displayed in an overlapping manner, the overlapped portion becomes difficult to see. Normally, the display color of the molding condition memo data Dm is considered to be easy to see even if it overlaps by using a relatively conspicuous color such as red, but the molding condition memo data Dm and the image data Dv When the colors are substantially the same, it is inevitable that the molding condition memo data Dm is difficult to read. Therefore, in this case, the check mark is removed from the check box in the image data display selection unit 53, and the selection not to display the image data Dv is performed (step S27). As a result, although the molding condition memo data Dm and the image data Dv are both displayed, the background of the molding condition memo data Dm is changed to the second screen V2 (steps S30, S29, S26). This state is indicated by an arrow F3 in FIG. Therefore, in this case, although the memo data Dm is displayed as it is, most of the image data Dv is masked by the second screen V2, as shown in FIG. Only the part Dvp ... located in the part Es ... is displayed.
[0034]
Therefore, since the background of the display part of the molding condition memo data Dm is white, the problem that the molding condition memo data Dm is difficult to read is avoided. In addition, since the slit-shaped portion Es... Having a predetermined width is provided only in the ruled line portion where the molding condition memo data Dm is not displayed, the molding condition memo data Dm is not affected at all. On the other hand, since a part of the image data Dv is displayed through the slit-shaped portion Es ... in the ruled line portion where the molding condition memo data Dm does not exist, the presence of the image data Dv can be known. For example, even if the operator changes in the middle, the operator after retreat can know the existence of the image data Dv, so a check mark is put in the check box in the image data display selection unit 53 to redisplay the image data Dv. be able to.
[0035]
According to the data display method according to the present embodiment, when displaying the molding condition memo data Dm, it is determined whether or not there is image data Dv related to the molding condition memo data Dm. The molding condition memo data Dm is displayed superimposed on the data Dv, and the background Bs of the molding condition memo data Dm is white (non-transparent) having a first screen V1 that is all transparent or a transparent slit-shaped portion Es. Since the second screen V2 can be selected, both the image data Dv and the molding condition memo data Dm can be displayed in the maximum size even on the molding condition memo display portion Vm whose size is restricted. Therefore, the visibility is improved, and the operator can easily and reliably (sufficiently) recognize the image content and the memo content. In particular, when the molding condition memo data Dm and the image data Dv overlap and it is difficult to see the molding condition memo data Dm, the molding condition memo data Dm can be easily viewed by selecting the second screen V2. Moreover, since the molding condition memo data Dm and the image data Dv overlap, the molding condition memo data Dm can include a simple image description (comment) that can directly explain a specific portion of the image data Dv. Therefore, it is possible to further improve convenience.
[0036]
Such molding condition memo data Dm includes precautions and various information related to molding condition data Ds such as “perform color change firmly” and “mold temperature control: 80 ° C.” as shown in FIG. The image data Dv can include images related to appearance photographs and drawings of molded products, and images related to various documents such as production plans and instructions. Therefore, papers in the factory can be unnecessary or reduced.
[0037]
On the other hand, the general-purpose memo data De stored in the controller 20 is displayed on the general-purpose memo display section Ve. General-purpose memo data De can include general-purpose messages for the use of the injection molding machine M such as “Tools are organized” and “Grease remaining amount warning”, general-purpose data such as the next maintenance date, etc. .
[0038]
In the setup screen Va, the operator can easily perform setup according to the displayed guidance. In particular, since each memo data Dm, Dv, and De are displayed together on the setup screen Va, the operator uses comments on peripheral equipment information and points to be noted regarding delicate adjustments as important reference information. it can. At the time of setup, if a plurality of item selection buttons B1, B2, B3, B4,... Provided corresponding to the type of setup on the setup screen Va are selected, guidance for individual operations related to the selected predetermined setup. Since the messages are sequentially displayed on the guidance display unit or the like along the work procedure, the operator can easily and reliably perform the setup work according to the guidance.
[0039]
Although the embodiments have been described in detail above, the present invention is not limited to such embodiments, and the detailed configuration, arrangement, quantity, method, and the like can be arbitrarily set within the scope of the present invention. Can be changed, added or deleted. For example, in the second screen V2, the case where the ruled line portion that does not display the memo data Dm is made transparent by the slit-shaped portion Es... Having a predetermined width is not excluded. Moreover, although white was illustrated as a color of background Bs, arbitrary colors can be used. On the other hand, the image data Dv and the memo data Dm are shown on the molding condition memo display portion Vm of the setup screen Va, but can be displayed on all or a part of an arbitrary screen if necessary. Further, the memo data Dm includes memo data related to molding conditions, and the image data Dv includes an image related to a molded product and an image related to a document, but is not limited thereto.
[0040]
