DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for setting operating conditions in an injection molding machine having a display device capable of displaying various mode images.

[0002]

2. Description of the Related Art A recent microcomputer-controlled injection molding machine is provided with a display device such as a color CRT display and a color LCD display. The display device sets or confirms molding operation conditions for automatic molding operation. Operation mode setting mode image, actual measurement data display mode image to display actual measurement data of many measurement items during automatic molding operation, inspection items are automatically displayed at the time of periodic inspection, and periodic inspection is performed. A periodic inspection mode image for prompting, an alarm mode image for recognizing this when an abnormality occurs, and the like are switched and displayed.

[0003] In this type of injection molding machine,
For each mold exchange (for each product), suitable molding operation condition values corresponding to the individual product shape, resin material, etc. are sequentially and interactively input to the display image while the various operation condition setting mode images are being called.・ It is designed to be set. That is, in order to perform precision molding, a recent injection molding machine sets operation condition values over a wide variety of items. For this reason, an image for setting operation conditions is divided into several images, for example, an injection process. When setting the operation conditions, call the injection operation condition setting mode image to make input settings and charge (weigh)
At the time of setting the operation condition of the stroke, the charge operation condition setting mode image is called to perform the input setting.

[0004]

As described above, in the conventional injection molding machine, in order to set the operating conditions of a certain stroke, the operation condition setting mode image of this stroke is switched to the operating condition of another stroke. In order to make the setting, it is necessary to switch to the operation condition setting mode image of another process, and the operation condition can be set only for the process (condition) of the currently displayed operation condition setting mode image. Was. By the way, among the operation condition data of the injection molding machine, there are not a few things to be set by referring to the data of other strokes, but in the conventional injection molding machine, the operation condition of a certain stroke is set. If it is necessary to refer to the setting data of the operating conditions of another process or change the setting data of the operating conditions of another process, the operating condition setting mode image is temporarily switched to that for another process. After that, it has been pointed out that the setting operability is poor because it is necessary to return to the original operation condition setting mode image. In addition, when monitoring the current operating state with various measured data display mode images, there are not a few situations where it is desired to change the operating conditions, but in this case also, the operating condition setting mode image of the desired stroke is displayed. It has been pointed out that the setting data of the operating conditions must be changed by switching, and the operating condition setting data cannot be changed while monitoring the operating state.

[0005] The present invention has been made in view of the above points,
The purpose thereof is to enable the setting of molding operation conditions of a desired stroke (condition) in a display state of an arbitrary display mode image, and thus to operate the injection molding machine with good operability and good usability. It is to provide a condition setting method.

[0006]

According to the present invention, there is provided a display device capable of displaying various mode images.

[0007]

When the operator desires to change the operation condition setting data of a certain stroke while an arbitrary display mode image is displayed, that is, for example, while monitoring an actually measured graphic image of a certain stroke, When the operator wishes to change the setting data of the operating conditions, the operator calls the window image for setting operation of the desired process by key operation as appropriate and displays the window, and refers to the display data of the actually measured graphic image, Change the operating conditions above. As a result, the changed operating condition data is stored in the predetermined storage area of the system controller (microcomputer), and the operating condition of the next shot is controlled using the changed and set operating condition. Further, for example, if a new setting or a change setting of the setting data of another process is desired in a state where the operation condition setting mode image of a certain process is displayed, the operator appropriately operates the window for setting operation of another process by key operation. The image is called up and displayed in a window, the operating conditions are set in the same manner on the setting operation window image, and this is stored in a predetermined storage area of the system controller (microcomputer).

This microcomputer 1 actually has various I
In the present embodiment, a molding condition setting storage unit 11 and a molding process control unit 12 are used to execute various types of processing by using various programs created in advance. The following description will be made assuming that the apparatus includes the measured value storage unit 13, the display processing unit 14, the key input processing unit 15, and the like.

Various operating condition values input by the key input device 4 via the key input processing unit 15 are rewritably stored in the molding condition setting storage unit 11. The operation condition values include, for example, the relationship between the screw position and the screw rotation speed during the charge stroke, the screw retreat speed, and the back pressure, the suck back control condition, the injection start point (position) to the pressure holding switching point (position). Injection speed conditions and primary injection pressure conditions up to the holding pressure switching time from the holding pressure switching time to the holding pressure end time, the band heater temperature of each part,
Mold closing (mold closing) stroke and speed control conditions, mold clamping force, mold opening stroke and speed control conditions, eject control conditions, control conditions for automatic product unloading machine, and the like.

The molding process control unit 12 is based on a molding process control program created in advance and setting condition values stored in a molding condition setting storage unit 11, and the sensor group 2 provided in each unit of the machine is controlled. While referring to measurement information from (position sensors, pressure sensors, temperature sensors, etc.) and time measurement information from a clock incorporated therein, through the driver group 3 (motor drivers, hydraulic cylinder drivers, heater drivers, etc.) The drive of the corresponding drive source is controlled to execute a series of molding steps.

The actually measured value storage section 13 stores all actually measured data of preset monitor items during continuous automatic operation over a predetermined number of consecutive shots. The monitored items to be captured include a time monitoring item, a position monitoring item, a rotation speed monitoring item, a speed monitoring item, a pressure monitoring item, a temperature monitoring item, a power monitoring item, and the like. Are almost overlapped.

The display processing section 14 displays display image data of a designated display mode based on a display image creation / control program created in advance by a command to call a display image in a mode desired by the operator via the key input device 4. Create That is, when a call instruction of a predetermined display image by the operator arrives, the display processing unit 14
If necessary, data for use in displaying the display mode image is extracted from the information stored in the molding condition setting storage unit 11 or the actual measurement value storage unit 13, and the display mode of the display mode image in which these are designated is extracted. Is converted to a form corresponding to. For example, if the designated display mode is a graphic image of a certain process, the extracted data is converted into image data that has been subjected to line drawing at a predetermined enlargement / reduction ratio, or the designated display mode is a certain display mode. If the image is an operation state setting image of a process, the extracted data is converted into numerical image data. Further, the display processing unit 14 extracts data to be used for displaying the display mode image, from fixed data for many mode images, such as characters, symbols, graphic figures, and ruled line data, which are created and stored in advance. Then, the fixed data and the converted image data are combined to create image data for a designated display mode, and this is displayed on the display screen of the display device 5. The display processing unit 14 generates window image data specified by the same processing as described above when a predetermined window image call command is received by a key operation as appropriate in an arbitrary display mode image display state. A part of the currently displayed display mode image is displayed as a window image. Furthermore, in the display state of the predetermined image, numerical data and the like appropriately input from the key input device 4 via the key input processing unit 15 are taken into the display processing unit 14 and converted into numerical image data and the like. It is synthesized as a part of the image data.

The key input processing unit 15 appropriately converts a signal input from the key input device 4 by an operator, and sends a display image generation / switching request command and numerical input data to the display processing unit 14. Then, it sends operation condition data to the molding condition storage setting unit 11 and sends a signal for instructing execution / stop of operation to the molding process control unit 12.

FIG. 2 is a diagram showing a measured graphic image of the injection stroke called by an appropriate key operation by the operator. In the actually measured graphic image of the injection stroke, the injection speed and the injection pressure are displayed as a graphic image together with the set values, so that the state of the change in the speed and the pressure of the injection stroke can be grasped at a glance. Also, in the initial display state of the actually measured graphic image of the injection process,
In the current display state of the actually measured graphic image, display characters indicating functions assigned to the function keys in the key input device 4 are displayed at the bottom of the image.

Now, if the operator wants to change the setting data of the operating conditions of the injection stroke while monitoring the graphic image of the actual measurement of the injection stroke shown in FIG. The function switching key is pushed to switch the function of the function key, and a window image call function for setting operation of each process assigned to the function key is displayed at the bottom of the image as shown in FIG. Then, in this state, by pushing a function key corresponding to the display of “eject”, the display processing unit 14 generates window image data for setting operation of the injection stroke, and displays this in the measured graphic image of the injection stroke. 3 is displayed as an injection stroke setting operation window image 21 as shown in FIG. Next, the cursor is moved to the numerical data setting column of the desired item on the injection stroke setting operation window image 21 while confirming the current measured speed and measured pressure with the measured graphic display data, and the set value of the set value is set by the numerical keys. By performing an update input and pushing a confirmation (enter) key, for example, the update input operation condition data is transferred to the molding condition setting storage unit 11, and the setting data of the setting item is updated and registered. The changed setting data is immediately reflected in the injection operation control of the next shot, whereby the measured speed and measured pressure of the shot after the condition change can be confirmed by the measured graphic display data. Therefore, in this case, since the change setting of the operating condition can be performed while confirming the actually measured data, the change item and the change amount can be appropriately indicated, and the operating state after the change can be immediately confirmed, and the setting of the good molding condition can be performed. Can be performed quickly and easily.

In this embodiment, in addition to the above-described window image 21 for the injection stroke setting operation, as shown in the function key function display portion of FIG. A window image for the setting operation of the “weighing (charge)” process, a window image for the setting operation of the “mold opening / closing” process, and a window image for the setting operation of the “mold pressure” condition are provided. These are arbitrary display mode images. Can be called as a window image in the display state of. Further, in the present embodiment, the setting items in each setting operation window image are suppressed to a necessary and sufficient number of items directly related only to each process and condition, so that the setting operation can be performed quickly without hesitation. Considered. When the setting operation window image does not fit in the window display area, the window image can be scrolled in the window display area. Note that the types of the setting operation window images described above are given as typical examples, and it is obvious to those skilled in the art that window images for setting operations of other processes and conditions can be prepared.

FIG. 4 shows a state in which the window image is set from the window image 21 for the injection stroke setting operation by pushing a function key corresponding to the display of "weighing" in the display state of FIG. It is a figure showing the state switched to the window image 22 for operation. In the state of FIG. 4, it is possible to set the operation conditions of the weighing (charging) process on the weighing process setting operation window image 22.
