The display processing unit 15 includes a data conversion processing unit 20, a fixed display data storage unit 21, An image data generation unit 22 and the like are provided.

Various operating condition values input by the key input device 4 or the like are stored in the molding condition setting storage unit 11 in a rewritable form. The operation condition values include, for example, the tightening force, the relationship between the screw position during the charge stroke and the screw rotation speed, the screw retreat speed, and the back pressure, suckback control conditions, and the injection speed from the start of injection to the holding pressure switching. Conditions, primary injection pressure conditions, secondary pressure (holding pressure) switching conditions, holding pressure conditions from the time of holding pressure switching to the end of holding pressure, 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, 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. The driver group 3 (motor driver) is referred to while referring to data from the actually measured value storage unit 13 that captures measurement information from a position sensor, a pressure sensor, a temperature sensor, and the like in real time and time measurement information from a clock incorporated therein. , Hydraulic cylinder driver,
A corresponding drive source is driven and controlled via a heater driver, etc., and a series of molding steps are executed.

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 print output processing unit 14 generates and transmits print data which has been prepared in advance by an operator instructing the print output of desired data with the key input device 4 interactively with an appropriate display image on the display device 5. Based on the control program, specified print data is created, and the print data is transmitted to the printer 6 in a transmission mode corresponding to the printer model selected by the operator.

That is, when a print output command for data desired by the operator arrives, the print output processing unit 1
The data conversion processing unit 16 of 4 extracts data to be used for the print output from information stored in the molding condition setting storage unit 11 and the measured value storage unit 13 as necessary, and specifies these data. The print output is converted into a form corresponding to the print form. For example, if the designated print output is a comparison table between the setting data of a certain process and the actual measurement data, the extracted data is converted into a numerical code for printing. Then, the conversion processing data of the data conversion processing unit 16 is taken into the print output data generation unit 18. Various kinds of fixed data such as characters, symbols, graphic figures,
Data to be used for the print output is extracted from the ruled line data and the like, is taken into the print output data generation unit 18, and is combined with the conversion processing data of the data conversion processing unit 16 as data for print output. On the other hand, when the operator requests a print output of the display image on the display device 5, the print output data generation unit 18 receives data transfer from a display image data generation unit 22 of the display processing unit 15, which will be described later. Is converted into print output data and stored as necessary.

The print data in the print output data generator 18 is transmitted to the printer 6 connected to the microcomputer 1 via the transmission controller 19. The transmission control unit 19 has a data transmission mode corresponding to the printer model selected by the user.
A data transmission mode corresponding to a printer connected to the microcomputer 1 (injection molding machine) is set in advance by an operator, and a transmission start command corresponding to the printer is transmitted to the connected printer 6. Is dot image data, the data is sequentially transmitted in a bit string order suitable for the connected printer. If a data transmission mode that does not correspond to the connected printer 6 is selected, the transmission control unit 19 recognizes this by a response command from the printer 6 to the transmission start command, and outputs a "printer selection error" or the like. A display is provided to alert the operator.

The display processing unit 15 is adapted to display display image data of a designated display mode based on a display image creation / control program created in advance by a call instruction of a display image of a mode desired by the operator using the key input device 4. Create That is, when a command to call a predetermined display image arrives from the operator, the data conversion processing unit 20 of the display processing unit 15 reads the information stored in the molding condition setting storage unit 11 and the measured value storage unit 13 as necessary. Data to be used for displaying the display mode image is extracted, and the data is converted into a form corresponding to the specified display mode of the display mode image. 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. And
The generation processing data of the data conversion processing unit 20 is taken into the display image data generation unit 22. On the other hand, a plurality of fixed data for a mode image, such as characters, symbols, graphic figures, and ruled line data, which are created and stored in advance in the display fixed data storage unit 21, are used for displaying the display mode image. The data is extracted,
This is taken into the display image data generation unit 22 and is synthesized as image data for display together with the generation processing data of the data conversion processing unit 20. As a result, the display image data generation unit 22 creates the image data for the designated display mode, and holds the rewritable image data.
Then, the image data of the display image data generation unit 22 is transmitted to the display device 5 according to a command of the display processing unit 14, and image data of a predetermined mode is displayed on the display screen of the display device 5. Will be. The image data of the display image data generation unit 22 is also sent to the print output processing unit 14 as needed.

FIG. 2 is a diagram showing a printer model setting image called up by a predetermined key operation of the key input device 4.
As shown in FIG. 2, in this embodiment, a representative model can be selected for each printer maker, the cursor is moved to a desired model name on the display image of FIG. 2, and the confirmation key is pushed. By doing so, the transmission control unit 19
Takes a data transmission mode corresponding to the printer model selected by the user.

By doing so, data can be transmitted to the printer in a print output format corresponding to each of different types of printers connected by the user, and the printer of any type that the user has can be transferred to the injection molding machine. The print output can be obtained by connecting, thereby greatly improving the convenience for the user.
