Abstract

An operating element for an injection molding machine comprises a monitor screen (10) for visual representation of program data. Over the monitor screen (10), a touch screen (12) is fitted for performing input functions according to the screen representation. Further provided is at least one function key field (14,16,18) flanking the monitor screen (10) and function keys (20). The function keys (20) are not provided as press-on keys which would have to be cabled separately, but are integrated into the touch screen (12). For this purpose, the touch screen (12), for forming the at least one function key field (14,16,18), laterally projects the monitor screen (10).

Claims

1. An operating element for an injection molding machine, comprising:

a monitor screen for visual representation of program data,

a touch screen fitted over the monitor screen and provided for program selection according to the screen representation, and

at least one function key field flanking the monitor screen and including pre-assigned function keys,

wherein,

for forming said at least one function key field, the touch screen laterally projects beyond the monitor screen.

2. The operating element according to claim 1 wherein the function keys of the function key field are provided as permanent representations on the touch screen.

3. The operating element according to claim 1 wherein the function keys are formed as a design film.

4. The operating element according to claim 1 wherein the representations of the function keys are provided on a rear side of a portion of the touch screen projecting beyond the monitor screen.

5. The operating element according to claim 1 wherein at least a part of the function keys are coupled to an optical display for status indication.

6. The operating element according to claim 5 wherein the optical display for status indication is implemented in the monitor screen, particularly in the peripheral region of the monitor screen in the immediate vicinity of the corresponding function key.

7. A display and input apparatus for a molding machine, comprising:

a video monitor;

a translucent touch screen mounted to a display screen of the video monitor such that a display on the display screen is visible through the touch screen, the touch screen being larger than the display screen such that a portion of the touch screen extends beyond the display screen;

representation of function keys permanently marked on the portion of the touch screen that extends beyond the display screen such that functions can be selected touching corresponding marked function keys.

8. The display and input apparatus according to claim 7, further including:

indicator lights mounted behind a rear face of the portion of the touch screen that extends beyond the display screen adjacent the marked function keys for indicating a status of corresponding functions.
