Abstract

A protective shield device for a travel rail is provided, the travel rail including at least one robot with an application element coupled thereon. The protective shield device comprises at least one protective shield component for protecting the travel rail from the application medium, e.g. paint, dispensed by the application element of the at least one robot. The protective shield device is configured to extend over a portion of the travel rail and to move relative to the travel rail.

First claim

The invention claimed is:

1. A coating installation assembly comprising:
a laterally extending travel rail;
a first and a second robot mounted for lateral movement on the travel rail in a spaced relationship; at least one of the first and second robots including an application element for dispensing a coating, and;
a protective shield coupled to the travel rail to slidably move on the travel rail, the protective shield being located between the first and second robots, the protective shield not rigidly connected to either the first or second robots, the protective shield having a height spanning the travel rail such that the travel rail is substantially entirely shielded, and the protective shield including slide contacts.

2. The coating installation assembly of claim 1 wherein the protective shield further comprises an upper flange and a lower flange, the upper and lower flanges shaped toward the travel rail.

3. The coating installation assembly of claim 2 wherein the protective shield includes an elastic buffer.

4. The coating installation assembly of claim 1 wherein the protective shield is freely mounted to the travel rail.

5. The coating installation assembly of claim 4 wherein the protective shield is connected to the first robot with a pliable tensile force transmitting part.

6. The coating installation assembly of claim 5 wherein the pliable tensile force transmitting part is a rope.

7. The coating installation assembly of claim 1 wherein the protective shield further comprises a drive device.

8. The coating installation assembly of claim 7 wherein the driving device includes a frictional wheel.

9. The coating installation assembly of claim 1 wherein the protective shield further comprises a dispensing unit for dispensing a lubricant.
