Abstract

A slip ring transmitter for electrically connecting assemblies of rotary-table machines is described and comprises a slip ring with a signal unit for transmitting signals and/or data and with a power unit for transmitting electrical power. As the signal unit is formed such that it is modularly detachable can in particular be axially drawn off from the power unit, the signal unit can be inspected and/or replaced separately from the power unit. This improves the reliability of the transmission of signals and/or data and enables individual optimization of the power unit.

First claim

The invention claimed is:

1. A slip ring transmitter for electrically connecting assemblies of rotary-table machines, comprising:
a slip ring with a signal unit for transmitting signals and/or data and with a power unit for transmitting electrical power,
wherein said signal unit is a first module comprising ring tracks and said power unit is a second module comprising slip tracks, and wherein said first module can be detached from said second module while said second module is installed in the slip ring transmitter.

2. The slip ring transmitter according to claim 1 , where said power unit is configured for contact transmission and said signal unit for non-contact transmission.

3. The slip ring transmitter according to claim 2 , where said signal unit is configured for optical, inductive and/or capacitive signal transmission.

4. The slip ring transmitter according to claim 1 , where said slip ring comprises plug terminals for electrically connecting said signal unit by way of said power unit.

5. The slip ring transmitter according to claim 1 , further comprising a housing with at least one inspection opening for passing said power unit through.

6. The slip ring transmitter according to claim 1 , further comprising a brush block with brushes for contacting said power unit.

7. The slip ring transmitter according to claim 1 , further comprising at least one inspection opening in the housing for exchanging said brushes.

8. The slip ring transmitter according to claim 1 , where electrically and/or optically detectable wear indicators are formed on said brushes.

9. The slip ring transmitter according to claim 1 , where said power unit comprises slip tracks made of brass.

10. The slip ring transmitter according to claim 1 , further comprising a partition wall in a housing for shielding said signal unit from said power unit and retaining graphite dust.

11. The slip ring transmitter of claim 10 , wherein the partition wall retains graphite dust via hermetic sealing.

12. The slip ring transmitter according to claim 1 , where said power unit comprises modularly stackable insulator segments and slip ring segments with slip tracks.

13. The slip ring transmitter according to claim 1 , where said slip ring segments can be stacked with the slip tracks axially contacting each other.

14. The slip ring transmitter of claim 1 , wherein the signal unit is modularly detachable from said power unit by being axially drawn off.

15. A slip ring transmitter for electrically connecting assemblies of rotary-table machines, comprising:
a slip ring with a signal unit for transmitting signals and/or data;
a power unit for transmitting electrical power, wherein said signal unit is modularly detachable from said power unit; and
a housing and an extractor for removing dust by suction from a housing section surrounding said power unit.

16. A rotary-table machine for producing, filling, sealing, labeling, printing, cleaning and/or inspecting containers with a slip ring transmitter, the slip ring transmitter comprising:
a slip ring with a signal unit transmitting signals or data;
a power unit transmitting electrical power, wherein said signal unit and the power unit are separate modules mounted on a support, and the signal unit is modularly detachable from said support and power unit.

17. The rotary-table machine according to claim 16 , where said signal unit can be exchanged while said power unit is installed in said rotary-table machine.
