Abstract

A device for displaying measuring values is provided, comprising a device for displaying measuring values having a control unit (22) and having a digital display unit (21), which is controlled by the control unit (22), wherein the control unit (22) is embodied in such a manner that a measuring value detected by the measuring value detection unit are displayed on the display unit (21) as actual value (I) and as a preset set value (S) in such a manner that the position of the actual value (I) relative to the set value (S) is a function of the difference between the set value and the actual value.

Claims

1. A device for displaying measuring values, said device having a control unit, a measuring value detection unit and digital display unit, which is controlled by the control unit, wherein the control unit is structured and arranged such that a measuring value detected by the measuring value detection unit as an actual value and a preset set value are displayed on the display unit in such a manner that the position of the actual value relative to the set value is a function of the difference between the set value and the actual value.

2. The device according to claim 1, wherein the control is structured and arranged such that the distance between the actual value displayed on the display device and the displayed set value changes chronologically according to the difference between the set value and the actual value.

3. The device according to claim 2, wherein the control is structured and arranged such that the actual value approaches the set value in a line of the display device or moves away from the set value according to the difference between the set value and the actual value at the moment of the detection.

4. The device according to claim 2, wherein the control is structured and arranged such that the movement of the actual value relative to the set value takes place in one line or in a plurality of lines of the display device.

5. The device according to claim 1, further comprising one or more graphics elements, which display the direction of the change of the difference between actual value and set value, and which are inserted between the display of the actual value and the display of the set value.

6. The device according to claim 1, wherein the control is structured and arranged such that the display of the actual value and of the set value coincide at a difference between set value and actual value of zero.

11. A shrink tunnel for a packaging machine, in particular, for a deep-drawing machine comprising a device for displaying measuring values according to claim 1.

12. The shrink tunnel according to claim 11, further comprising a temperature measuring device and wherein the device displays temperature values.

13. A packaging machine comprising a device for displaying measuring values according to claim 1.

14. The packaging machine according to claim 13, wherein it is a deep-drawing machine or a chamber machine.

7. A method for displaying measuring values, said method comprising:

detecting a measuring value by a measuring value detection device,

digitally displaying an actual value and a set value, wherein the position of the actual value relative to the set value is displayed as a function of the difference between actual value and set value.

8. The method according to claim 7, wherein the local distance between the actual value and the set value corresponds to the difference between the actual value and the set value.

9. The method according to claim 8, wherein the distance changes chronologically according to the actual value detected at a moment.

10. The method according to claim 7,

further comprising providing graphics symbols, which characterize the direction of the change of the difference between set value and actual value, and which are arranged between the actual value and the set value.
