Abstract

An operating unit includes a touch-sensitive display screen for displaying an operating program, a control or regulating unit for communicating operating signals to injection molding machine elements, and the operating program is stored in the control or regulating unit, and at least one operating button, upon the actuation of which the control or regulating unit triggers an action of an injection molding machine element. The operating program has a hierarchical system architecture with at least one upper installation-specific level and an upper task-specific level. A selection can be made between different installation regions in the installation-specific central level, between different task regions in the task-specific central level, and a plurality of sublevels. Process-relevant program pages associated only with the selected installation region or only with the selected task region can be displayed in each selected sublevel.

First claim

at least one operating button ( 6 ), upon an actuation of which the control or regulating unit ( 4 ) triggers a corresponding action of one of the injection molding machine elements ( 5 ),
wherein the operating program (B) has a hierarchical system architecture comprising:
at least one upper installation-specific level (M 1 ), wherein a selection is provided between a plurality of different installation regions (L 1 -L 5 ) in the at least one upper installation-specific level (M 1 ),
an upper task-specific level (M 2 ), wherein a selection is provided between a plurality of different task regions (F 1 -F 5 ) in the upper task-specific level (M 2 ), and
a plurality of sublevels (U 1 -U 6 ), wherein process-relevant program pages (P) associated only with a selected one of the plurality of different installation regions (L 1 -L 5 ) or only with a selected one of the plurality of different task regions (F 1 -F 5 ) are displayed in a respective one of the plurality of sublevels (U 1 -U 6 ),
wherein at least one trigger symbol (A) is displayed on each of the process-relevant program pages (P),
wherein the corresponding action of the one of the injection molding machine elements ( 5 ) is triggered by the actuation of the at least one operating button ( 6 ) associated with the at least one trigger symbol (A),
wherein, depending on the at least one trigger symbol (A), upon the actuation of the at least one operating button ( 6 ), one of the operating signals (S) is communicated by way of the control or regulating unit ( 4 ) and the operating program (B) to the one of the injection molding machine elements ( 5 ) and the corresponding action is performed,
wherein the injection molding machine elements ( 5 ) include a movable mold mounting plate ( 5 a ), an injection screw ( 5 b ), and heatable and coolable molding tools ( 5 c ), and
wherein a representation of an entire production cycle of the injection molding machine ( 2 ) is effected/displayed when the at least one upper installation-specific level (M 1 ) is selected.

2. The operating control unit as set forth in claim 1 , further comprising a main level (H 1 ) in which a selection is provided between an installation-specific menu (N 1 ) and a task-specific menu (N 2 ).

3. The operating control unit as set forth in claim 2 , wherein the main level (H 1 ) and at least one of the installation-specific menu (N 1 ) and the task-specific menu (N 2 ) are simultaneously represented.

4. The operating control unit as set forth in claim 1 , wherein the at least one upper installation-specific level (M 1 ) and the upper task-specific level (M 2 ) are of equal rank in the hierarchical system architecture.

5. The operating control unit as set forth in claim 1 , wherein machine-specific parameters (R) are displayed on the process-relevant program pages (P).

6. The operating control unit as set forth in claim 1 , wherein the process-relevant program pages (P) of the selected one of the plurality of different installation regions (L 1 -L 5 ) or the selected one of the plurality of different task regions (F 1 -F 5 ) are displayed in succession only in a given sequence.

7. The operating control unit as set forth in claim 6 , further comprising navigation buttons ( 7 ) displayed in at least one of the plurality of sublevels (U 1 -U 6 ), wherein by actuation of the navigation buttons ( 7 ) the process-relevant program pages (P) are sequentially displayed or in a reverse of the given sequence.

8. The operating control unit as set forth in claim 1 , further comprising a hierarchy button ( 8 ) displayed at least in an upper level (M) and in at least one of the plurality of sublevels (U 1 -U 6 ), wherein a higher hierarchal level (H, M) is displayed by actuation of the hierarchy button ( 8 ).

9. The operating control unit as set forth in claim 1 , wherein the process-relevant program pages (P) of the plurality of different installation regions (L 1 -L 5 ) are different from the process-relevant program pages (P) of the plurality of different task regions (F 1 -F 5 ).

10. The operating control unit as set forth in claim 1 , wherein the hierarchical system architecture further comprises a metalevel (Z) which is selectable independently of a displayed level (H, M, U).

11. A method of operating an injection molding machine ( 2 ), comprising:
displaying on a touch-sensitive display screen ( 3 ) an operating program (B) having a hierarchical system architecture,
communicating operating signals (S) by a control or regulating unit ( 4 ) to injection molding machine elements ( 5 ), the operating program (B) being stored in the control or regulating unit ( 4 ),
actuating at least one operating button ( 6 ), to trigger a corresponding action of one of the injection molding machine elements ( 5 ) by the control or regulating unit ( 4 ),
displaying an entire production cycle of the injection molding machine ( 2 ) in an upper installation-specific level (M 1 ) or an upper task-specific level (M 2 ) in dependence on a previously selected menu (N 1 , N 2 ) or a preset selection,
selecting an installation region (L) from various displayed installation regions (L 1 -L 5 ) or a task region (F) from different displayed task regions (F 1 -F 5 ), and
displaying a sublevel (U 1 -U 6 ) in dependence on the selected one of the various displayed installation regions (L 1 -L 5 ) or the selected one of the different displayed task regions (F 1 -F 5 ), wherein process-relevant program pages (P) associated only with the selected one of the various displayed installation regions (L 1 -L 5 ) or only with the selected one of the different displayed task regions (F 1 -F 5 ) are displayed in each selected sublevel (U 1 -U 6 ),
wherein at least one trigger symbol (A) is displayed on each of the process-relevant program pages (P),
wherein the corresponding action of the one of the injection molding machine elements ( 5 ) is triggered by actuation of the at least one operating button ( 6 ) associated with the at least one trigger symbol (A),
wherein, depending on the at least one trigger symbol (A), upon the actuation of the at least one operating button ( 6 ), one of the operating signals (S) is communicated by way of the control or regulating unit ( 4 ) and the operating program (B) to the one of the injection molding machine elements ( 5 ) and the corresponding action is performed, and
wherein the injection molding machine elements ( 5 ) include a movable mold mounting plate ( 5 a ), an injection screw ( 5 b ), and heatable and coolable molding tools ( 5 c ).

12. The method as set forth in claim 11 , further comprising at least one of:
