[Means for Solving the Problems]

In the data output method of the injection molding machine according to the present invention, when outputting the data of the injection molding machine, the molding monitor data Dm1 ... Obtained from the operation of the injection molding machine is output in time series for each shot, and the molding failure occurs. Based on the above, history data including at least one or more error items De1, molded product quality determination items Di1 input from the input device 1, and molding condition change items Ds1 ... are formed in the shot in which the history data is generated. The monitor data Dm1 ... is output next. In this case, the output of data includes at least one of output formats of recording, storage, display, and communication.

[Action]

 Next, the operation of the present invention will be described.

According to the data output method of the present invention, since the molding monitor data Dm1 ... and various history data based on molding defects are gathered and arranged in time series, a series of history situations in the molding work process are organically combined. It can be used as data.

〔Example〕

Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the data processing system of the injection molding machine that realizes the method of the present invention will be described with reference to FIG.

In the data processing system S, 2 is a controller attached to the injection molding machine. A display 3 such as a CRT, a plasma display, a liquid crystal display or an EL display is connected to the controller 2 to display data. The controller 2 is connected to the input device 1 having a setting panel on which various numeric keys, function selection keys, etc. are arranged, a printer 5 for printing out data, and an external computer 7. The external computer 7 is connected to the controller 2 via the communication interface 6 to exchange data with the controller 2 and to store data, perform arithmetic processing, and the like. As the communication interface 6, for example, a GP-IB interface,
RS-232C interface, optical communication, etc. can be used.

Next, regarding the data output method using the system S,
A description will be given with reference to FIG.

The figure shows a data sheet 10 printed out from the printer 5.

First, the molding conditions are set and stored in the controller 2 by operating the setting panel of the input device 1. Therefore, when the injection molding machine is operated, molding is performed based on the set molding conditions, and the filling time of the injection molding machine, the plasticization time,
It is possible to obtain molding monitor data such as the injection start position, the injection end position, the most advanced position, and the measurement start position. This molding monitor data is obtained for each shot and printed on the data sheet 10 as molding monitor data Dm1. The molding monitor data Dm1 is obtained as an absolute value or a deviation value with respect to the set monitor range, and a representation format such as a graph format can be selected by a setting panel of the input device 1 as necessary.

Next, assume that a molding failure occurs.

In the case of the example, the most advanced position "2.2" in shot "3"
"1" indicates that the monitor range has been exceeded.
In this case, the history data based on the occurrence of the molding defect is arranged next to the molding monitor data in the shot “3”. That is, the error item De1 including the shot number "3" in which the molding failure occurs, the occurrence time "18:11", the error code "0909", and the error name "most advanced position over"
Are arranged as data respectively. Further, the operator visually checks the molded product and inputs the defective product name “burr” from the setting panel of the input device 1. This causes the error item
Next to De1, the molded product quality determination item Di1 is arranged by the name of "burr". Furthermore, the operator operates the setting panel of the input device 1 to change the molding condition for eliminating the molding failure. This change data is set in the controller 2 and next to the pass / fail judgment item Di1. Items for changing molding conditions displayed with "Nozzle temperature 195.0 ° C → 190.0 ° C"
Ds1 arranges.

Then, by repeating the molding cycle again, normal molding monitor data can be sequentially obtained.

It should be noted that the data sheet 10 shows the case where defective molding (error item) occurs at shot numbers “5” and “6”, but these cases are similarly processed. That is, after the molding monitor data Dm2 including shots "4" and "5", the shot number "5" in which the molding failure has occurred, the occurrence time "18:16", and the error code "0900".
And the error item De containing the error name "Filling time under"
2, molded item quality judgment item D by "short shot" name
i2, the temperature of the heating cylinder is changed to “Zemb temperature 206.0 ° C → 215.0 ° C” and the change item Ds2 of the molding condition is displayed. on the other hand,
Next to the molding monitor data Dm3 including the shot "6", an error item De3 due to "filling time under" occurring in the shot "6" is displayed, but it shows that the molded product is a good product. In this case, the operator inputs the name "OK" indicating that it is a good product as the molded product quality determination item Di3, and changes the monitoring range as the molding condition change item Ds3 "filling time lower limit 0.60 mm → 0.57 mm". It is set.

Further, the molding monitor data Dm4 is displayed next to the history data based on the shot "6", and finally the statistical table H regarding the molding monitor data and the history data is displayed.

As described above, on the data sheet 10 printed out from the printer 5, in addition to the molding monitor data Dm1, various history data based on molding defects are arranged together with shot numbers, times, etc., and preferably arranged in time series. Therefore, it is possible to confirm at a glance how the molding history changes in accordance with the setting of the molding conditions or the change thereof.

Although FIG. 1 exemplifies the case where the printer 5 outputs the data in the print format, the same data can be displayed on the display 3 as the output format, or can be transferred (communication) to the external computer 7 and stored. Good. These can be selected on the setting panel of the input device 1 and executed individually or simultaneously.

Although the embodiments have been described in detail above, the present invention is not limited to such embodiments. For example, data relating to changes in molding conditions, molding defects, etc. can be output separately from the molding monitor data and can be selected on the setting panel of the input device. Further, as the history data, arbitrary items related to the molding work are applied, including the various items illustrated. Furthermore, the storage format is a concept including an internal memory of the external computer illustrated, an IC card, an external memory (magnetic memory), an optical disk, and the like.
In addition, the configurations and methods can be arbitrarily changed without departing from the scope of the present invention.

〔The invention's effect〕

As described above, the data output method of the injection molding machine according to the present invention, the molding monitor data obtained from the operation of the injection molding machine,
While outputting in time series for each shot, history data including at least one error item based on molding failure, molded product quality determination item, one or more items of molding condition change item,
Since the history data is output next to the molding monitor data in the shot in which the history data is generated, the following effects are obtained.

Since various data based on the operator's own judgment can be output together with the data obtained from the operation of the injection molding machine, comprehensive understanding and analysis of various data obtained during the molding work process can be performed easily, and the data is effective. Utilization and simplification of AI methods can be achieved.
