  Further, in the injection molding machine 1 of the present embodiment, as shown in FIG. 3, users are classified hierarchically into a plurality of groups according to the type of work of the user who operates the injection molding machine 1. According to the group, it is possible to set so that the specific operation item given to each group is displayed on the menu screen 31 displayed on the display unit 20 as shown in FIGS. In addition, in order to display a specific operation item corresponding to a group on the menu screen 31, it is necessary to input “user name” and “password” by the operation of the touch panel 22 each time to perform login authentication. Further, in the plurality of groups divided in the hierarchy in this embodiment, the “producer” of “1” is the highest hierarchy, and the hierarchy is lowered in the order of “1” to “6”, as shown in FIG. "Simple" is the lowest hierarchy. Then, when the setting corresponding to the group is performed in advance, the setting information is stored in the storage unit 50.

  Here, an example in which the specific operation item given to each group is displayed on the menu screen 31 will be described with reference to FIGS. For example, as the specific operation items given to the “simple” group of “6”, as shown in the menu screen 31 of FIG. 4, “injection / plasticization”, “mold opening / closing EJ”, “temperature setting” , "Product control", "Replacement", "Inspection screen", "Password", and specific operation items given to the "Maintenance" group of "4" are shown in the menu screen 31 of FIG. “Injection / Plasticization”, “Type open / close EJ”, “Temperature setting”, “Production control”, “Injection graph”, “Monitor”, “Replacement”, “Inspection screen”, “Option operation”, "Password", "plasticization assistance", "core", "automatic heater input", "operation process", "plasticization graph", "monitor item", "10 monitor screen", "alarm history", "option" "Signal", "Language switching", "Air", "1 cycle Graph "," monitor display "," injection compression "," communication port setting "," mold open / close option "," setting history "," one cycle logic "," monitor graph "," forming navigation "," gate cut " , “Time setting”, “1 cycle graph item selection”, “monitor reserve”, “option confirmation”, “viscosity measurement”, “unit setting”, “1 cycle logic item selection”, “molding condition diagnosis”, “menu 2 ”. As described above, the specific operation items assigned to the lowermost hierarchy "simple" group are smaller than the specific operation items assigned to the higher hierarchy "maintenance" and the like in this embodiment. In the “simple” group, where the user's job type is “introductory molding person in charge”, the group with the least importance is the least.

  Next, on the premise that there are a plurality of injection molding machines 1 set so that specific operation items given to each group are displayed on the menu screen 31 of the display unit 20, injection molding is performed using the USB 30 memory. An operation method for displaying a desired operation item on the menu screen 31 of the display unit 20 of the device 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 USB port 25 of any one injection molding machine 1 of the plurality of injection molding machines 1 is used. , USB memory 30 is connected. Next, as shown in FIG. 6, the screen selection screen 32 is displayed on the display unit 20 of the injection molding machine 1 to which the USB memory 30 is connected, and “OFF” of “screen selection” at the top of the screen selection screen 32 Switch the display to "ON".

  Next, a plurality of operation items (“plasticization assistance”, “condition list”, “core”, “air”, “mold opening / closing option”, “heater automatic injection”, Mold temperature "," operation process "," condition memory "," setting history "," injection graph "," plasticization graph "," 1 cycle graph "," 1 cycle graph item selection "," 1 cycle logic item " "Select", "Graph Spare", "Monitor", "Monitor Item", "Monitor Display", "Monitor Graph", "Monitor Spare", "10 Monitor Screen", "Forming Navi", "Option Confirmation", "Forming" Condition diagnosis "," Alarm history "," Option operation "," Option signal "," Ejection compression "," Gate cut "," Viscosity measurement "," Language switching "," 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 PID 2", "Temperature control PID 3", "Amplifier monitor", "Environment setting 2") Among them, the operation item to be displayed on the menu screen 31 is selected from non-display (OFF) to display (ON) (state shown in FIG. 7).

  Next, as shown in FIG. 8, the password screen 33 is displayed on the display unit 20 by a predetermined operation, and the “user name” and the “password” can be input on the password screen 33. Press "User Registration (USB)" at the top. Then, enter the desired “user name” and “password” in the “user name” and “password” input fields displayed on the password screen 33, and for “re-enter (re-enter)” for reconfirmation. Enter "Password" too. In the present embodiment, as shown in FIG. 8, “user name” is “ABC” and “password” is “XYZ”.

  After entering "user name" and "password", pressing "OK" on password screen 33, "ABC" which is the entered "user name" and "XYZ" which is "password", as shown in FIG. The operation item selected as the display (ON) is stored in the USB memory 30.

  Then, for example, when it is necessary to display the operation item stored in the USB memory 30 with any one of the plurality of injection molding machines 1, the operation item, the user to the USB port 25 of the injection molding machine 1 The USB memory 30 storing the name and the password is connected, and "Change user" is pressed on the password screen 33 displayed on the display unit 20 based on the connection, and the "list" shown in FIG. 9 displayed accordingly To pull down and use the data stored in the USB memory 30, select "USB_user" from the "list" to be pulled down. Then, as shown in FIG. 10, “ABC” which is a user name stored in the USB memory 30 is displayed on the upper part of the password screen 33.

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

  In addition, 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, and the injection molding machine 1 to the USB memory When the camera 30 is removed and disconnected, the list of operation items displayed on the menu screen 31 is hidden. Further, when the list of operation items displayed 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, the specific operation item given to the lowermost 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 for which a restriction is set so that a specific operation item is displayed according to the group to which the user belongs. In this case, connect the USB memory 30 storing the operation item, user name and password to the injection molding machine 1 that you want to use, and enter the password etc. in that state, and the input password is connected to the injection molding machine 1 If it is determined that the password matches the password stored in the USB memory 30, the operation item can be displayed on the menu screen 31 of the display unit 20. Therefore, for example, in the case where there are a large number of injection molding machines 1, by connecting the USB memory 30 to each injection molding machine and inputting the password, the USB memory which is the operation item desired easily in each injection molding machine 1 It is possible to display the operation items stored in 30 and the convenience is high.

  Further, the USB memory 30 is connected to the injection molding machine 1, and it is judged whether the password input in the password input field of the password screen 33 matches the password stored in the USB memory 30 or not. If it is determined that the password is determined, the operation item stored in the USB memory 30 is displayed on the display unit 20. However, the operation item is displayed only based on the determination of whether or not the passwords match. The USB memory 30 itself storing the operation item, the user name and the password rather than being displayed on the menu screen 31 of the unit 20 is a requirement for displaying the operation item on the menu screen 31 of the display unit 20. In other words, the USB memory 30 substitutes for the key, which can enhance security.

  Furthermore, when the USB memory 30 storing the operation item, the user name and the password is connected to the injection molding machine 1 and the operation item is displayed on the menu screen 31 of the display unit 20, the USB memory from the injection molding machine 1 30 is removed from the display unit 20 of the injection molding machine 1 and the menu screen 31 on which the operation item is displayed is switched to non-display on the basis of security. Can enhance the safety of Then, when the menu screen 31 in which the operation item is displayed is switched to non-display, a specific operation item assigned to “simple” which is the lowest group among the plurality of groups is set as a default on the display unit 20. By being displayed on the menu screen 31 (the state shown in FIG. 4), the specific operation item given to the lowermost group having a relatively low importance is displayed on the display unit 20, thereby the security Convenience can be improved while maintaining the above safety.
