Abstract

PROBLEM TO BE SOLVED: To provide a display unit for setting history of an injection molding machine which visually displays how set values were changed when trials were repeated by varying set values of parameters. SOLUTION: A display unit contains an input-portion 11 for inputting various set values, a memory portion 12 for storing input set values, a display unit 13 for displaying the set values and a controller 14 to which the input portion, the memory portion and the display portion are connected. When a set value is changed, the controller makes the memory portion store the changed value and when there is an indication of displaying input setting history from the input portion, the controller displays a list of the recorded set values of each parameter in the order from the new one to the old one.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control system for an injection molding machine having a plurality of kinds of parameters. The present invention relates to a setting history display method and a setting history display device of an injection molding machine for displaying well.

[0002]

2. Description of the Related Art In a control system of an injection molding machine having a plurality of types of parameters, conditions to be considered during operation,
That is, the parameters cover a large number of parameters such as resin temperature, resin injection pressure, holding pressure, and mold temperature. When setting the molding conditions at the start of operation, while changing the set values for each of the above parameters, monitoring what quality of the molded product was obtained, and monitoring the parameters for obtaining good quality Calculate the set value of.

In such an operation, naturally, the set values of the parameters are displayed on a display, and the settings are changed using a data input unit such as a keyboard, a mouse, or a touch pen. As a setting history display function up to now, as shown in FIG. 3, a method of displaying a list of set values of various parameters on a display screen and storing the set values in a storage device for a certain number of setting changes is provided. is there. FIG. 3 shows, as an example, a display example in the plasticizing step, in which the previous various set values are displayed in the upper half area, and the current various set values are displayed in the lower half area.

Therefore, when it is desired to view the setting change two times before, it can be viewed by instructing it through the data input unit.

[0005]

The setting history display function as described above is convenient when a large number of types of setting changes are made. However, in the case of setting the molding conditions, the set value is changed in one or two types, and in order to know how the one type has been changed, the instruction through the data input unit must be repeatedly performed. troublesome. In addition, if the setting change is repeatedly displayed several times, the initial value may be forgotten.

An object of the present invention is to provide a setting history of an injection molding machine capable of displaying, with good visibility, how the set value has been changed when a trial is repeated while changing the set value of a parameter. A display method and a setting history display device are provided.

[0007]

According to the present invention, there is provided a method for displaying a setting history of an injection molding machine, wherein when setting conditions for the injection molding machine are changed, various setting values are changed in order to change the molding conditions. The changed setting values are stored in the storage unit, and the changed setting values can be displayed as a list on the display unit in the new setting order for each type, if necessary.

A setting history display device for an injection molding machine according to the present invention includes an input unit for inputting various set values, a storage unit for storing the input set values, and a display for displaying the set values. And a controller connected to the input unit, the storage unit, and the display unit, and the controller, when there is a change input of a set value, causes the storage unit to store the change input, and receives an input from the input unit. When there is an instruction to display a history of set values, a list is displayed on the display unit in the order of new settings in accordance with the type of the set value input.

In the setting history display device, the setting value is assigned an ID for each type, and the ID is stored in the storage unit.
Is stored for each storage area defined by.

In this setting history display device, the set value is displayed together with the setting change time.

Further, in the setting history display device, the history display of the set values is displayed on a pop-up screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A setting history display device according to an embodiment of the present invention will be described with reference to FIGS.
In FIG. 1, the setting history display device includes a data input unit such as a keyboard for inputting various setting values, an input unit 11 using a mouse or a touch pen, and a storage unit 12 for storing input setting values. , A display 13 for displaying set values, an input unit 11, a storage unit 12, and a controller 14 connected to the display 13. When there is a change input of the set value, the controller 14 stores it in the storage unit 1.
2, when there is an instruction from the input unit 11 to display the history of the input set values, the display unit 13 displays the list in the new setting order according to the type of the input set values. The components described above need not be provided exclusively for the present setting history display device. That is, it is also possible to substitute an element provided as a control system of the injection molding machine.

Particularly, in the present embodiment, an ID is assigned to each of a plurality of types of set values, and when a set value including a change is input, the controller 14 causes the storage unit 12 to store in the storage area specified by the ID. It is stored every time. As a result, when the operator specifies the ID that the user wants to confirm on the input unit 11,
The controller 14 reads out all the data in the storage area specified by the specified ID and causes the display 13 to display the data.

FIG. 2 shows a setting history display example relating to the dwell time. In particular, in the present embodiment, the history display of the set value regarding the dwell time is displayed together with the setting change time. This can be achieved by using the timekeeping function of the controller 14 to store the change setting value and the time at that time when there is a change input of the setting value. Further, in the present embodiment, the history display of the set values in FIG. 2 is displayed on a pop-up screen. As is well known, the pop-up screen is a display method for displaying a screen on an existing screen on the display 13 when the screen is already displayed. Therefore, in the present embodiment, if the setting history display is designated while the screen as shown in FIG. 3 is displayed in the molding condition setting, it is superimposed on the screen as shown in FIG. Such a screen can be displayed. The screen as shown in FIG. 2 can be erased by designating the specific area with the cursor and clicking the mouse.

As described above, according to the present setting history display device, the history data relating to the desired setting value can be displayed in a list in a new order by a simple operation as necessary, so that the operator can determine how the desired setting value is. It is possible to know what value has been changed over time.

[0016]

As described above, according to the present invention, it is possible to determine how the set values are changed when the trial is repeated while changing various set values when setting the molding conditions of the injection molding machine. It can be displayed with good visibility.
