The processing machine know-how support system according to the present invention has been provided so far. It differs from a guidance-based support system. For example, when the processing machine is an injection molding machine, a skilled engineer of the injection molding machine manufacturer accumulates all the know-how of the process of setting the molding conditions with his or her own injection molding machine in the database or the recording medium. On the other hand, on the user side of the injection molding machine, even if the operator is an inexperienced operator, if a molding failure occurs while molding with the injection molding machine, refer to the database or recording medium for the molding failure. It is a system that supports to deal with.

An embodiment in which the present invention is applied to an injection molding machine will be described below. Hereinafter, the processing machine know-how support system according to the present invention will be referred to as a molding know-how support system.

The present molding know-how support system can be realized by a structure that can be connected to the control device of the injection molding machine by a communication means to construct a database. An ordinary PC is connected to the control device of the injection molding machine by communication means.
A (personal computer) is sufficient and has a database memory as an internal or external storage device. Of course, this PC is a communication terminal in a remote place (domestic or overseas), for example, P by a communication network such as the Internet.
Can communicate with C. Further, the control device of the injection molding machine can always retrieve the data from the database constructed by this molding know-how support system by the communication means. The extraction method may be Web technology, file sharing, or a dedicated protocol.

With reference to FIGS. 1 and 2, the present molding know-how support system is realized as follows.

[System registration procedure] 1) Accumulation of know-how by a skilled engineer of the injection molding machine manufacturer (Fig. 1) 1-1. A skilled engineer sets various molding conditions when a molded product is produced by an injection molding machine. At that time, the molding conditions are corrected to cope with various defects of the molded product. The modification process is as follows.

A. Checking the molded product (when defective molding occurs) b. Change the molding condition items that are considered necessary from experience.

C. Check the molded product after changing the molding conditions.
At this time, if there is molding failure again, b. It will be redone from the work of.

D. If the product is non-defective, the modification of the molding conditions is completed.

The above-mentioned steps a to d are the same operations as so-called forming of molding conditions, but the present invention further includes the following operations.

1-2. Information for a cause input screen as shown in the upper right of FIG. 1 is stored as a change cause list in the memory in the PC or in the control device of the injection molding machine. Here, the following are the causes of defective molding: Short shot, 2. Bali, 3. Burnt 4. Whitening, 5. Jetting, 6. Stringing, 7. Weld line, 8. Abnormal cushion, 9. Mold maintenance, 11. Other, can be displayed. In the item b of the above-mentioned molding condition correction process, the skilled engineer displays the change cause list in the memory in the PC or the controller of the injection molding machine on the screen by the display when the item of a certain molding condition is corrected. Display and select the cause of defective molding from the displayed change cause list.

Various display forms can be considered as the display method of the change cause list, but the display form is not limited in the present invention. As a reason, what is necessary in the molding condition correction process is to select or enter the cause when the molding condition is changed, and to relate the changed item and its content and the cause that needs to be changed. This is because any form may be used.

An example of the change input screen after selecting the cause of the defective molding is shown in the lower right part of FIG. Here, the case where burr is selected as the cause is shown, the name of the molded product, the molding condition name,
Items of molding conditions, change contents, and reason columns are displayed as a change content list, and burrs are displayed in the reason columns. The expert engineer inputs the contents actually changed in the injection molding machine on the change input screen. That is, the molded product is a case, the molding condition name is Case 1, the item of the molding condition is a holding pressure of 1 step (T1), and the set content is changed from 10 to 15.

By the above-mentioned work, it is possible to correlate the molding condition with correction of the molding condition, that is, which molding condition was changed and how.

1-3. The related information is transmitted to the PC by the communication means and registered in the database.

1-4. In the database, which item of the molding condition is changed and how much is changed due to a certain molding defect is recorded in a form including information on the molded product and the molding condition. Of course, instead of the database, for example, a portable recording medium may be used, and the point is that the above relationship may be recorded in some recording medium.

It should be noted that the database constructed as described above repeats the above-mentioned steps 1-1 to 1-4, and every time a molding failure occurs, the contents of the measures taken are added and the know-how is added. Will be fulfilled. This also applies to a portable recording medium. In other words, in the case of a portable recording medium, a copy thereof is attached to the injection molding machine and shipped, so that it is not possible to add the content, but the recording medium with the new content is provided as an upgraded version. As a result, the know-how to be provided can be enhanced regardless of the existing injection molding machine or the new injection molding machine.

[System usage procedure] 2) Use of a molding know-how support system by an inexperienced operator after the injection molding machine is shipped (FIG. 2) The controller in the shipped injection molding machine is in the above 1) via communication means. The databases mentioned can be referenced.

B. An inexperienced operator checks whether or not the molded product is a good product in the molding process.

B. If the molded product is defective, the operator calls the change cause list from the above database by communication means, or calls the change cause list from the recording area that is pre-recorded in the memory in the control unit of the injection molding machine to perform injection molding. Display on the machine display.

C. As shown in the upper right of FIG. 2, the cause of defective molding is selected from the change cause list on the cause input screen displayed on the display. This change cause list is
This is the same as the cause input screen of FIG.

D. When a defect cause is selected on the cause input screen, the molding condition items and their changes related to the selected defect cause by the accumulated know-how in the database, that is, the set value before the change and the changed value after the change. The setting value and the setting value are displayed as a condition change list in descending order of accumulation frequency.

In the lower right part of FIG. 2, an example of the condition changing screen when the selected defect cause is a short shot is shown. Here, the first place of the accumulation frequency is to raise the set value of the first holding pressure from 20 to 25, and the second place is to raise the measured value from 150 to 200. Also, the third place is back pressure of 7
From 9 to 9.

As described above, it is an important point in the molding know-how support system according to the present invention to display the condition change list in descending order of accumulation frequency. In other words, all information is recorded in the know-how construction described in 1) above. Therefore, in the present molding know-how support system, it is possible to use the information processing function of the PC to sort out the recorded information, for example, defects by product, defects by molding condition, or measures by cause. Of course, when using the know-how accumulated in the database, it is possible to select what kind of information organization is necessary, or it is possible to use it in the form of information that has been organized in advance.

E. The operator performs the above-mentioned a) by changing the molding condition so as to increase the setting value of the first stage of the holding pressure with the highest accumulation frequency. If it is a non-defective product, the change of molding conditions is completed.

By the above-mentioned work, even an operator who is inexperienced in determining molding conditions or a molded product for the first time can perform molding by utilizing the know-how of a skilled engineer by the molding know-how support system.

In the above description, in the system registration procedure, the cause input screen for displaying the change cause list and the change input screen for changing the settings are used.
In the system utilization procedure, a cause input screen for displaying the change cause list and a condition change list display screen are used. In addition to displaying such information, the following information may be displayed in addition to the database.

That is, for each failure cause in the change cause list displayed on the cause input screen, the cause, countermeasure, and specific case can be displayed as guidance information. 3 shows an example of a short shot, and FIG. 4 shows an example of a weld line. Such guidance information also
In the system registration procedure, the cause, countermeasure, and specific case are initially displayed in a blank state on the display, and the skilled engineer inputs the contents that can be considered when the molding condition is corrected due to molding failure in the process of accumulating know-how. Created in this way and registered in the database. Needless to say, if the possible contents of the defective molding due to the same cause are different from the contents described so far, the know-how accumulated in the database can be enhanced by adding the contents.

In the system use procedure, even an inexperienced operator should check the change cause list and change the conditions before
By looking at the guidance information screens as shown in FIGS. 3 and 4 corresponding to the defective molding, it is possible to refer to the judgment of the condition change.

The above molding know-how support system can also be applied to a so-called plural machine management system of an injection molding machine. As shown in FIG. 5, the multiple-unit management system includes a plurality of injection molding machines 10-1 to 10-n at the same location.
Is installed, and these are management devices 20 with a display.
It is managed collectively in. That is, the management device 20 is connected to the respective control devices in the injection molding machines 10-1 to 10-n, and various control signals from various sensors installed in the injection molding machines 10-1 to 10-n are used. Information is received via each control device, the received information is processed for each injection molding machine based on a built-in management program, and the processed result is stored in a built-in memory or an external memory and displayed on a display as a management screen.

When such a plural-unit management system is applied to the molding know-how support system, the management device 20 functions as the PC described above in the system registration procedure. The skilled technician repeats the above-mentioned operations 1-1 to 1-4 to construct the database in the built-in memory or the external memory by the management device 20. The more injection molding machines there are, the faster the database construction will be and the more complete the contents will be. Of course, the management device 20 can communicate with an external terminal device by communication means such as the Internet.

On the other hand, in the system utilization procedure, when only one injection molding machine is shipped, an unskilled operator performs the above-mentioned operations a) to e). Further, in the case of a multiple-unit management system similar to that shown in FIG. 5, the management device is used to perform the above-mentioned operations a) to e).

The present invention can be applied not only to the molding condition setting in the injection molding machine but also to the controllers of various processing machines that require setting. In addition, if the accumulated know-how uses modern IT technology, the know-how accumulated in Japan can be used overseas, or an immature operator can record the molding condition setting situation by the know-how accumulation procedure later. It is also possible for experts to check and use it for education and training. Furthermore, the know-how accumulated in the database can be copied to a recording medium and used in another factory.

In the above-described embodiment, the example in which the injection molding machine for accumulating know-how and the injection molding machine for receiving the know-how are installed separately has been described. The injection molding machines provided may be the same. In this case, when molding is performed by an injection molding machine and a defective product is obtained at that time, a registration work is performed to store and save the information about the change of the setting condition and the cause as know-how in the database each time. Then, when a defective product is generated when the same injection molding machine is operated by another operator, for example, the cause of the defective product generation is dealt with by referring to the database.
Of course, as described above, when a defective product is generated in the registration work, a change cause list showing a plurality of types of failure causes is displayed on the display, and the corresponding failure cause is selected from the plurality of types of failure causes. When is selected, a change content list showing the content of change necessary to eliminate the selected cause of failure is displayed.When the content of change is entered in the change content list, the content of change and the cause of failure are identified. They are related and stored as know-how in the database. Then, by continuing the registration work, the information accumulated in the database continues to increase. Further, when a corresponding failure cause is selected from the plurality of kinds of failure causes, all information related to the selected failure cause among the information registered in the database is displayed on the display as a condition change list. Then, the contents of the change are selected from the displayed condition change list and the setting is changed, so that the cause of the defective product is eliminated.

As described above, even if the injection molding machine for accumulating know-how and the injection molding machine for receiving the know-how are the same, the above-described embodiments are applied as they are.
Of course, this also applies to the case of an ordinary processing machine.
