The present invention is a method of operating a molding machine having a plurality of users who use the molding machine, and selects the plurality of users for each group, and the operation method in a molding machine with display restrictions depending on the group to which the user belongs. About.

For example, a molding machine that performs molding and processing of an article typified by an injection molding machine has its operation controlled by a microcomputer as a control means, and has high productivity and high accuracy of a molded product. In such a microcomputer-controlled molding machine, the operating conditions need to be set in advance, and the molding machine is operated according to the set operating conditions. Therefore, if the “operating condition” is erroneously set or is intentionally changed to a wrong setting, the apparatus will malfunction. The prior art regarding such a problem is disclosed by patent document 1 etc.

Japanese Patent Laid-Open No. 2004-1555066

By the way, the prior art disclosed by the above-mentioned patent document 1 groups “operating conditions (system parameters)”, so that the setting / changing operation of predetermined operating conditions (system parameters) is double ( By requiring a plurality of passwords, an operation for setting / changing the “operation condition” is prevented from being erroneously performed. Change is supposed to be impossible.) According to this, although it can be said that it is excellent in terms of security of protection from an erroneous operation, when performing stepwise grouping, a plurality of passwords are required (for example, the number of groups is five levels). In such a case, five passwords are required according to the number of groups), which may be complicated in terms of operability.

In addition to the operation setting and changing operations, the microcomputer-controlled molding machine as described above performs various operations such as operations to operate the molding machine and operations for maintenance and management of the molding machine. In many cases, there are a plurality of users who are familiar with each operation. That is, a molding person who sets or changes molding conditions for molding machines for each molded product, a serviceman who sets up the basic settings for initial settings and maintenance of molding machines, and simply operates (runs) the molding machine. There are a plurality of users such as an operator in charge of starting / stopping, an administrator such as a factory manager who manages the molding machine and users, and the like. However, for security management, when a plurality of users are grouped and restrictions are given so that only specific display and operation can be performed for each group, for example, a specific person can display and operate across multiple groups. Each time, as a user for each group, you must enter a password and log in, and you will not be able to perform the desired operation. The number of screens that must be displayed more than necessary may increase the operability.

The present invention has been made in view of the above problems, and the object thereof is a molding machine in which there are a plurality of users who use the molding machine and the display is limited according to the group to which the user belongs from the viewpoint of security. It is an object of the present invention to provide a method for operating a molding machine that improves operability while improving security.

Invention of the operation method of this molding machine
According to the type of job of the user who operates the molding machine, the user is hierarchically selected into a plurality of groups, and specific operation items assigned for each group are displayed on the display unit according to the selected groups. The operation method of the molding machine set as follows,
An external memory is connected to any one of the plurality of molding machines,
On the display unit of the molding machine connected to the external memory, display a screen selection screen that allows selection of operation items to be displayed
The operation item selected on the screen selection screen and the user name and password entered on the password screen displayed on the display unit are stored in the external memory connected to the molding machine,
When using another molding machine different from the molding machine used when storing the operation item, the user name and the password in the external memory,
Connect the external memory storing the operation item, the user name, and the password to the other molding machine, and display a password screen on the display unit of the other molding machine in that state, and the password of the password screen When it is determined that the password entered in the input field matches the password stored in the external memory connected to the other molding machine, the external memory is displayed on the display unit of the other molding machine. The operation items stored in the screen are displayed.

Furthermore, the invention of the operation method of this molding machine is
When the external memory is removed from the other molding machine and disconnected,
Based on this, the operation items displayed on the display unit of the other molding machine are switched to non-display.

Furthermore, the invention of the operation method of this molding machine is
When the operation item displayed on the display unit of the other molding machine is switched to non-display,
A specific operation item given to the lowest group among the plurality of groups is displayed on a display unit of the other molding machine.

According to the present invention, when there are a plurality of molding machines in which restrictions are set so that a specific operation item is displayed according to the group to which the user belongs, an external memory storing the operation item, the user name, and the password is stored. Connect to the molding machine you want to use and enter the password in that state. When it is determined that the input password matches the password stored in the external memory connected to the molding machine, the operation item can be displayed on the display unit. Therefore, for example, when there are many molding machines, the user can easily display operation items on each molding machine by connecting an external memory to each molding machine and inputting a password. High nature.

Furthermore, an external memory is connected to the molding machine, and it is determined whether or not the password entered in the password entry field on the password screen matches the password stored in the external memory. The operation items stored in the external memory are displayed on the display unit. However, the operation items are not displayed on the display unit based only on the determination of whether the passwords match. However, the external memory itself that stores the operation items, user name, and password is a requirement for displaying the operation items on the display unit, that is, the external memory serves as a key instead of a key. Can improve the safety.

Furthermore, when the external memory storing the operation item, the user name, and the password is connected to the molding machine and the operation item is displayed on the display unit, when the external memory is removed from the molding machine and is in a disconnected state, Based on this, since the operation item displayed on the display unit of the molding machine is switched to non-display, security safety can be enhanced. When the operation item is switched to non-display, the specific operation item assigned to the lowest group among the plurality of groups is displayed on the display unit of the molding machine. By displaying the specific operation items assigned to the lower groups on the display unit, it is possible to improve convenience while maintaining security safety.

Provide mechanism. As the mold opening / closing mechanism in the present embodiment, the movable link 8 is repeatedly opened and closed with respect to the fixed mold 6 by bending the toggle link mechanism 9 using a driving force of a motor (not shown) as a drive source.

Further, the injection unit 3 is provided with a cylindrical heating cylinder 11 having an injection nozzle 10 attached to the tip. The thermoplastic resin supplied into the heating cylinder 11 is kneaded while being heated by a screw 12 provided in the heating cylinder 11, weighed, and then injected into a mold cavity closed.

As shown in FIG. 2, the injection molding machine 1 has a storage unit 16 that stores the operating conditions and screen display information of the injection molding machine 1, and a mechanism control that controls the operation of the injection molding machine 1 according to the operating conditions. Unit 17, control unit 18 that controls the entire injection molding machine, display unit 20 that is an output interface for a user, and touch panel 22 that is used as an input unit 21 that is an input interface that receives input from the user, display on display unit 20 A USB for connecting a screen display processing unit 23 that performs control, an input processing unit 24 that performs discrimination of a signal from the input unit 21, and a USB memory (external memory) 30 that is separate from the injection molding machine 1. A port (connection unit) 25 is provided.

Moreover, in the injection molding machine 1 of this embodiment, as shown in FIG. 3, according to the job type of the user who operates the injection molding machine 1, the users are hierarchically sorted into a plurality of groups. Depending on the group, a specific operation item assigned to each group can be set to be displayed on a menu screen 31 displayed on the display unit 20 as shown in FIGS. In order to display a specific operation item corresponding to the group on the menu screen 31, the user operates the touch panel 22 each time to input the “user name” and “password” to perform login authentication. There is a need to do. Also, in the plurality of groups divided into hierarchies in this embodiment, “producer” of “1” shown in FIG. 3 is the highest hierarchy, and the hierarchy becomes lower in the order of “1” to “6”. “Simple” is the lowest hierarchy. And if a user performs the setting according to such a group previously, these setting information will be memorize | stored in the memory | storage part 50. FIG.

Here, an example in which specific operation items assigned to each group are displayed on the menu screen 31 will be described with reference to FIGS. For example, specific operation items assigned to the “simple” group of “6” include “injection / plasticization”, “mold opening / closing / EJ”, “temperature setting” as shown in the menu screen 31 of FIG. "Production management", "Exchange", "Inspection screen", "Password". Further, specific operation items assigned to the “maintenance” group of “4” include “injection / plasticization”, “mold opening / closing / EJ”, “temperature setting” as shown in the menu screen 31 of FIG. , “Production Management”, “Injection Graph”, “Monitor”, “Replacement”, “Inspection Screen”, “Option Operation”, “Password”, “Plasticizing Aid”, “Core”, “Automatic Heater”, “Operation Process”, “Plastification Graph”, “Monitor Item”, “10 Monitor Screen”, “Alarm History”, “Option Signal”, “Language Switch”, “Air”, “1 Cycle Graph”, “Monitor Display” ”,“ Injection compression ”,“ Communication port setting ”,“ Mold open / close option ”,“ Setting history ”,“ One cycle logic ”,“ Monitor graph ”,“ Molding navigation ”,“ Gate cut ”,“ Time setting ”, “1 cycle graph item selection”, “ Nita spare "," Tracking Options "," Viscosity measurement ", set" unit "," 1 cycle logic item selection "," molding conditions Diagnosis ", a" menu 2 ". As described above, the specific operation items assigned to the “simple” group in the lowest hierarchy have few specific operation items assigned to the group such as “maintenance” in the higher hierarchy. The “simple” group with the user's job type “beginner molding person in charge” is the least important group.

Next, on the premise that there are a plurality of injection molding machines 1 that are set so that specific operation items assigned for each group are displayed on the menu screen 31 of the display unit 20, injection molding is performed using a USB 30 memory. An operation method for displaying a desired operation item on the menu screen 31 of the display unit 20 of the machine 1 will be described below with reference to FIGS.

First, in order to enable operation items to be displayed on the menu screen 31 of the display unit 20 using the USB memory 30, the user can select the USB port of any one of the plurality of injection molding machines 1. The USB memory 30 is connected to 25. Next, as shown in FIG. 6, the user displays a screen selection screen 32 on the display unit 20 of the injection molding machine 1 to which the USB memory 30 is connected, and “screen selection” “ The display of “OFF” is switched to “ON”.

Next, the user operates a plurality of operation items displayed on the screen selection screen 32 (“plasticizing assistance”, “condition list”, “core”, “air”, “die opening / closing option”, “automatic heater on” ”,“ Mold temperature ”,“ operation process ”,“ condition storage ”,“ setting history ”,“ injection graph ”,“ plasticization graph ”,“ 1 cycle graph ”,“ 1 cycle graph item selection ”,“ 1 ” “Cycle logic item selection”, “Graph reserve”, “Monitor”, “Monitor item”, “Monitor display”, “Monitor graph”, “Monitor reserve”, “10 monitor screen”, “Forming navigation”, “Option check” , “Molding condition diagnosis”, “Alarm history”, “Option operation”, “Option signal”, “Injection compression”, “Gate cut”, “Viscosity measurement”, “Language switch”, “Communication port setting”, “Time” `` Setting '', `` Unit setting '', `` “Check 1”, “Semi-fixed value recording”, “Semi-fixed value 1”, “Semi-fixed value 2”, “Temperature control PID”, “Temperature control PID2”, “Temperature control PID3”, “Amplifier monitor”, “Environment” Among the setting 2 ”), the operation item to be displayed on the menu screen 31 is selected from non-display (OFF) to display (ON) (the state shown in FIG. 7).

Next, when the user performs a predetermined operation, a password screen 33 is displayed on the display unit 20 as shown in FIG. 8, and the user name and password can be input on the password screen 33. In order to do this, “User Registration (USB)” at the top of the password screen 33 is pressed. Then, enter the desired “user name” and “password” in the input fields of “user name” and “password” displayed on the password screen 33, and further enter “password (re-enter)” for reconfirmation. Also enter the “password”. In the present embodiment, as shown in FIG. 8, the “user name” is “ABC” and the “password” is “XYZ”.

When the user presses “OK” on the password screen 33 after inputting “user name” and “password”, in addition to the input “user name” “ABC” and “password” “XYZ”, The operation item selected as display (ON) in FIG. 7 is stored in the USB memory 30.

For example, when the user needs to display the operation items stored in the USB memory 30 on any one of the plurality of injection molding machines 1, the operation is performed on the USB port 25 of the injection molding machine 1. The USB memory 30 in which the item, user name and password are stored is connected, and “Change User” is pressed on the password screen 33 displayed on the display unit 20 based on the connection. In order to use the data stored in the USB memory 30 by pulling down “list”, “USB_user” is selected from the “list” to be pulled down. Then, as shown in FIG. 10, “ABC”, which is the user name stored in the USB memory 30, is displayed at the top of the password screen 33.

Here, as shown in FIG. 11, when the user inputs “XYZ” as a password in the password input field and presses “OK”, the control unit 18 stores the input password in the USB memory 30. It is determined whether or not it matches the existing password. When it is determined that they match, the screen display processing unit 23 displays a menu screen 31 on the display unit 20 based on a command from the control unit 18, and a USB memory is displayed on the menu screen 31 as shown in FIG. The operation items stored in 30 (operation items for which “ON” is selected in FIG. 7) are displayed as a list.

In order to display the operation items stored in the USB memory 30 as a list on the menu screen 31, the USB memory 30 must be connected to the injection molding machine 1. When 30 is removed and brought into a non-connected state, the list of operation items in the display state on the menu screen 31 is hidden. In addition, when the list of operation items in the display state on the menu screen 31 is not displayed, the screen display processing unit 23 is set in advance so that a specific operation item is displayed according to the group. However, a specific operation item assigned to the lowest hierarchy group is displayed on the menu screen 31 of the display unit 20.

As described above, according to the operation method of the injection molding machine 1 of the present embodiment, there are a plurality of injection molding machines 1 in which restrictions are set so that specific operation items are displayed according to the group to which the user belongs. In this case, the user connects the USB memory 30 storing the operation items, the user name, and the password to the injection molding machine 1 that the user wants to use, and inputs the password or the like in that state, and the input password is the injection molding machine. 1, the operation item can be displayed on the menu screen 31 of the display unit 20 when it is determined that the password matches the password stored in the USB memory 30 connected to 1. Therefore, for example, when there are a large number of injection molding machines 1, the user can easily select desired operation items on each injection molding machine 1 by connecting the USB memory 30 to each injection molding machine and inputting a password. The operation items stored in a certain USB memory 30 can be displayed, which is highly convenient.

Further, the USB memory 30 is connected to the injection molding machine 1, and it is determined whether or not the password entered in the password entry field of the password screen 33 matches the password stored in the USB memory 30. If it is determined that the operation item is stored, the operation item stored in the USB memory 30 is displayed on the display unit 20, but the operation item is displayed based only on the determination of whether or not the passwords match. Instead of being displayed on the menu screen 31 of the unit 20, the USB memory 30 itself storing the operation items, the user name, and the password is a requirement for displaying the operation items on the menu screen 31 of the display unit 20. In other words, the USB memory 30 is used as a key, thereby enhancing security safety.

Further, when the USB memory 30 storing the operation items, the user name, and the password is connected to the injection molding machine 1 and the operation items are displayed on the menu screen 31 of the display unit 20, the USB memory 30 is transferred from the injection molding machine 1 to the USB memory. On the basis of this, the menu screen 31 on which the operation items are displayed, which is displayed on the display unit 20 of the injection molding machine 1, is switched to non-display when the device 30 is disconnected and disconnected. Can improve the safety. When the menu screen 31 on which the operation item is displayed is switched to non-display, a specific operation item assigned to “simple” that is the lowest group among the plurality of groups is set as a default on the display unit 20. Since it is displayed on the menu screen 31 (the state shown in FIG. 4), a specific operation item assigned to the lowest group of relatively low importance is displayed on the display unit 20, so that security is achieved. It is possible to improve convenience while maintaining the above safety.
