Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a system parameter setting method for an injection molding machine that sets system parameters for determining a basic state of the injection molding machine.
[0002]
[Prior art]
In the injection molding machine, system parameters for determining a basic state, such as the presence / absence of use of a sensor and the rotation direction of a motor with respect to a command, are set. Since even one system parameter is an important parameter that cannot operate normally if the setting is different, a dip switch that is not touched by the user is usually provided inside the controller, and the setting can be made by switching this dip switch. ing. On the other hand, with the high performance and multi-functionality of the controller, it is possible to set (change) such system parameters on the screen displayed on the display. In this case, there is also a possibility that the user will accidentally open the screen and change the setting accidentally, and in order to avoid unnecessary troubles, it is necessary to take measures to prevent easy operation by the user. .
[0003]
Conventionally, as a countermeasure against such a setting operation, for example, a method for enabling / disabling the setting operation in an injection molding machine disclosed in JP-A-5-42576 is known. In this method, even if the operation condition setting mode image is called in the state where the setting operation disapproval mode is set, the operation condition setting (or change) operation is disabled, and the password is not allowed in the setting operation disapproval mode state. When the number input mode image is called and the operator inputs a password that matches the password registered in advance, the mode is shifted to a setting operation permission mode that enables setting of operating conditions.

[Problems to be solved by the invention]
However, the conventional method described above replaces the traditional method of using a dedicated key with a method of using a personal identification number, and can benefit from prevention of operation by others and prevention of loss of the dedicated key. However, when the operator enters the password and transitions to the setting operation permission mode, normal operation by the operator (user) becomes possible, and this is a measure for preventing easy operation by the user. Absent.
[0005]
The present invention solves such a problem existing in the prior art, and even when system parameters are set on the screen displayed on the display, easy operation by the user is prevented, and An object of the present invention is to provide a system parameter setting method for an injection molding machine that can avoid unnecessary troubles by protecting it.
[0006]
[Means for Solving the Problems and Embodiments]
In the system parameter setting method for an injection molding machine according to the present invention, when setting system parameters for determining the basic state of the injection molding machine M, all or part of the system parameters are classified into a plurality of different groups Gx.

[0012]
On the other hand, a bus line 30 similar to the bus line 24 is connected to the chip set 23 to constitute a PLC (programmable logic controller) control system. For this reason, the bus line 30 is connected with an input / output interface 31 for giving switching data Di such as a switch to the CPU 21 and giving control command data Do obtained from the CPU 21 to the corresponding actuator, and detection signals of various sensors. An input / output interface 32 is connected to apply Si to the CPU 21 after analog-to-digital conversion, and to apply a control signal So obtained by digital-to-analog conversion of control command data obtained from the CPU 21 to the corresponding actuator. Thus, a predetermined feedback control system and an open loop control system are configured.
[0013]
Therefore, the internal memory 25 stores the PLC program and the HMI program and various processing programs. The PLC program is software for realizing the sequence operation of various processes in the injection molding machine M, the monitoring of the injection molding machine M, and the HMI program is the setting and display of operation parameters of the injection molding machine M, injection This is software for realizing display of operation monitoring data of the molding machine M and the like. These software are constructed as a unique architecture of the injection molding machine M on which the controller 20 is mounted, and in particular, can execute processing of the system parameter setting method according to the present embodiment.
[0014]
Next, a system parameter setting method according to the present embodiment will be described according to a flowchart shown in FIG. 1 with reference to FIGS.
[0015]
FIG. 4 shows a state in which a password first input window Wi is displayed on the mold opening / closing screen Va displayed on the display 2. Now, it is assumed that only the normal mold opening / closing screen Va is displayed on the display 2. Therefore, the first input window Wi is not displayed. Note that the mold opening / closing screen Va is merely illustrated for convenience, and the type of the displayed screen Va is not limited.
[0016]
First, an outline of the mold opening / closing screen Va will be described. This mold opening / closing screen Va is one of setting screens for setting various conditions in the mold clamping process. On the upper and lower stages of the mold opening / closing screen Va, a plurality of screen switching keys K1, K2,. The screen switching keys K1... Are ranked in consideration of the frequency of use. In the upper part, the mold opening / closing screen switching key K1, the ejector screen switching key K2, the injection / weighing screen switching key K3, and the temperature screen switching key K4. The first group Ga related to the setting of the operating conditions of the molding machine having the monitor screen switching key K5, the main condition screen switching key K6, and the condition switching screen switching key K7 is arranged in a horizontal row, and in the lower part, A second group Gb having a setup screen switching key K8, a process monitoring screen switching key K9, a production information screen switching key K10, a waveform screen switching key K11, a statistical screen switching key K12, and a trend screen switching key K13 is arranged in a horizontal row. To do.
[0017]
The screen switching keys K1... Are displayed in the same manner even when the mold opening / closing screen Va is switched to another screen. For example, FIG. 2 shows an outline of the process monitoring screen Vb when the process monitoring screen switching key K9 is selected. Each screen switching key K1... Has the same shape at the same position as the mold opening / closing screen Va shown in FIG. Is displayed. Note that the second group Gb displayed in FIG. 4 is in a state where the first layer is displayed, but by touching the layer screen switching key Kc at the right end of the screen, the history screen switching key in the second layer, A program screen switching key, a signal recorder screen switching key, a diagnostic screen switching key, and the like are displayed in the same manner in such a manner that they are replaced with the screen switching keys K8 to K13. Further, the controller 20 has an array change function that can arbitrarily change the array of the screen switching keys K1... And an array storage function that stores the changed array. Accordingly, the user himself / herself can arbitrarily change the arrangement (order) of the screen switching keys K1. With such a layout display, even when the name display displayed on each screen switching key K1... Is changed, it can be easily handled by software, and man-hours and costs associated with the change can be reduced, and each screen switching key K1. Visibility and operability for ... can be improved.
[0018]
Then, a case where the user changes the system parameter from the mold opening / closing screen Va will be described. Although the system parameter is originally not changeable by the user, the case where the user changes is, for example, injection molding When a malfunction occurs in the machine M, there may be a case where the user calls the service station and receives a change instruction from the service person through the telephone.
[0019]
In this case, first, the user double touches the system key Km hidden at the upper right of the mold opening / closing screen Va (step S1). Since this system key Km is not displayed on the screen, it is only necessary to confirm the position and double-touch on the screen. As a result, the first input window Wi shown in FIG. 4 for inputting the password is displayed on the mold opening / closing screen Va (step S2). The first input window Wi has a password input field 50, an OK key Ko, and a cancel key Kca. Note that the password is obtained from the survin man, and the user inputs the password in the password input field 50 according to the message displayed in the first input window Wi (step S3). The password can be input from a keyboard (not shown) displayed simultaneously with the first input window Wi. If a password is entered, it is confirmed whether or not there is an error. If the password is entered correctly, the OK key Ko is touched. Thereby, the system screen Vs shown in FIG. 5 is displayed (steps S4 and S5).
[0020]
By adopting such a display method, even when the user accidentally double-touches the system key Ko and the first input window Wi is displayed, the user has not obtained a password. The system screen Vs cannot be displayed (step S4).
[0021]
On the other hand, the contents of the system screen Vs shown in FIG. 5 are as follows. First, all or part of the system parameters (parameters for determining the basic state of the injection molding machine M) are classified into different groups Gx. Then, setting keys Ks... For setting each parameter are displayed on the system screen Vs in units of classified groups Gx. That is, a group Gx related to assembly adjustment, a group Gy related to machine specifications, and a group Gz related to operation setting, and a plurality of setting keys Ks... Included in the group Gx related to assembly adjustment are displayed on the first screen of the system screen Vs. A plurality of setting keys Ks... Displayed on the part 51 and included in the group Gy related to the machine specification are displayed on the second display part 52, and further a plurality of setting keys Ks. Is displayed on the third display unit 53.
[0022]
In this case, system parameters included in the group Gy related to the machine specification include load cell use / non-use setting, assembly adjustment speed setting, speed command polarity setting, origin correction, encoder polarity setting, torque command offset setting, and the like. The system parameters included in the group Gy related to machine specifications include pulley tooth number setting, encoder type selection, encoder pulse number setting, rated rotation speed setting, ball screw / lead setting, and the like. Further, system parameters included in the group Gz related to the operation setting include speed loop gain setting, position loop gain setting, speed integration time constant setting, and the like. Such groups Gx... Can be classified in consideration of parameter attributes, maintenance, and the like, and maintainability can be improved by grouping a large number of system parameters.
[0023]
On the other hand, these groups Gx, Gy, Gz are ranked according to their importance, and the permission conditions for each rank are made different. In the case of the embodiment, two passwords are input as a condition for the group Gx related to assembly adjustment and the group Gy related to the machine specification, and one password is input as a condition for the group Gz related to operation setting. , Setting by the setting key Ks. Hereinafter, these processes will be specifically described.
[0024]
First, a case is assumed where setting (changing) is performed using the setting key Ks included in the group Gz related to the operation setting having a relatively low rank. In this case, four setting keys (selection keys) Ks... For selecting a setting group are displayed on the third display portion 53 of the system screen Vs. Now, assume that the selection key Ksc is touched (steps S6 and S7). Thereby, the sub-window Ws shown in FIG. 6 is displayed (step S8). In this sub-window Ws, setting keys Ks... For actually setting, that is, a total of six setting keys Ks... Related to the above-described speed loop gain setting, position loop gain setting, speed integration time constant setting, etc. are displayed. ing. Therefore, for example, the speed loop gain can be set by touching the setting key Ksv (steps S9 and S10). Ke is an EXIT key. As described above, the setting key Ks included in the group Gz related to the operation setting having a relatively low rank is permitted to be set by the setting key Ks... On condition that the password is input once by the first input window Wi.
[0025]
Next, it is assumed that the setting key Ks included in the group Gx related to assembly adjustment having a relatively high rank (the same applies to the group Gy related to the machine specification) is set (changed). In this case, the first display section 51 of the system screen Vs has setting keys Ks... For actually setting, that is, the above-described use setting of the load cell, assembly adjustment speed setting, speed command polarity setting, origin correction, etc. A total of fifteen setting keys Ks. Now, assume that the setting key Ksr is touched in order to change the use / non-use setting of the load cell (step S11). Thereby, the second input window Wj (see FIG. 4; not shown in FIG. 5) having the same form as the first input window Wi described above is displayed on the system screen Vs shown in FIG. 5 (step S12). Therefore, the user inputs a password in the password input field 50 according to the message displayed in the second input window Wj (step S13). The second password is preferably different from the first password, but may be the same. If a password is entered, it is confirmed whether or not there is an error. If the password is entered correctly, the OK key Ko is touched. As a result, the second input window Wj is closed and the setting key Ksr becomes valid (steps S14 and S15). That is, the setting by the setting key Ksr is permitted, and the setting change of whether or not the load cell is used can be changed by the setting key Ksr (steps S16 and S17).
[0026]
In this way, in particular, regarding the setting keys Ks... Included in the group Gx related to assembly adjustment of a relatively high rank (or the group Gy related to the machine specification), the first input window Wi and the second input window Wj are used twice. Since the setting by the setting key Ks... Is permitted on the condition that the password is entered, an easy operation by the user is prevented and the system parameters are protected, thereby avoiding unnecessary trouble.
[0027]
The embodiment has been described in detail above, but the present invention is not limited to such an embodiment, and the detailed configuration, arrangement, quantity, method, and the like can be arbitrarily set within the scope of the present invention. Can be changed, added or deleted. For example, the system parameters to be classified into groups are desirably all for the injection molding machine, but may be a part if necessary. Moreover, although the group showed the case where it classified into three groups, two may be sufficient and four or more may be sufficient. Furthermore, although the case where it divided into two ranks of high and low was shown, three or more may be sufficient. In this case, the password can be input three or more times according to the importance. The passwords at this time may be different or the same. On the other hand, a plurality of passwords corresponding to each group Gx... Or each rank are prepared, and setting for the group Gx... Or rank corresponding to the arbitrary password can be permitted on condition that an arbitrary password is input. The method is also included in one aspect in which permission conditions for each rank (each group Gb...) Are made different. In the embodiment, the sub window Ws is used. However, whether or not the sub window Ws is used is arbitrary, and a setting key Ks... Displayed on the sub window Ws is displayed on the third display unit 53 of the system screen Vs. Of course, it is possible to display it. The concept of “setting” in the present invention is a concept including various settings such as change, adjustment, and deletion as well as new setting.
[0028]
【The invention's effect】
As described above, the system parameter setting method of the injection molding machine according to the present invention classifies all or part of the system parameters into a plurality of different groups, and sets the setting keys for setting each parameter to the unit of the classified group. In addition to being displayed on the screen, the setting by the setting key is permitted on the condition that the password is input, and the following remarkable effects are obtained.
[0029]
(1) Even when system parameters are set on the screen displayed on the display, easy operation by the user is prevented, so that unnecessary trouble can be avoided by protecting the system parameters. .
[0030]
(2) Since many system parameters are classified (grouped) in consideration of attributes, maintenance, etc., maintainability can be improved.
[0031]
(3) According to the preferred embodiment, if the groups are ranked according to the importance, and the permission conditions for each rank are made different, the system parameters having a higher importance are further protected. For those with low importance, easiness of setting and the like are taken into consideration, so that both reliability and usability can be improved.
