Abstract

A system for painting objects having a plurality of ring lines extending along a painting booth, each ring line conducting an operating medium required for operating an application device provided in the painting booth. The ring lines are divided into at least two regions. A connection device connects at least some of the ring lines to the application device and has a terminal module. The terminal module includes at least as many ring line sections as there are ring lines. The ring line sections have terminals at the ends to connect to the ring line regions. A branch line branches off from each of the ring line sections, the branch line leading to a terminal device. The terminal device has an inner flow path via which at least some of the branch lines can be connected to an outlet terminal. At least one tube or a line connects the outlet terminal to the application device.

First claim

What is claimed is:

1. A system for painting comprising:
a) a painting booth;
b) at least one application device arranged in the painting booth, from which paint can be discharged onto objects;
c) a plurality of ring lines, which extend along the painting booth and each carry an operating medium needed for operation of the at least one application device;
d) at least one connecting device, via which at least some of the ring lines can be connected to the at least one application device as required;
wherein
e) each ring line is subdivided into at least two ring line regions;
f) the at least one connecting device has at least one factory-prefabricated terminal module, the at least one factory-prefabricated terminal module being connected to the at least two ring line regions of each ring line, between each of the at least two ring line regions, to complete each ring line, the at least one factory-prefabricated terminal module comprising
fa) at least as many ring line sections as there are ring lines, each ring line section having a terminal at each opposing end of the ring line section, wherein a first terminal of each ring line section connects to a first region of one ring line, and a second terminal of each ring line section connects to a second region of one ring line;
fb) for each ring line section, a branch line branching off from the latter;
fc) a terminal device, to which the branch lines lead and via which at least some of the branch lines can be connected to an outlet terminal;

g) at least one hose or a line connecting the outlet terminal of the at least one factory-prefabricated terminal module directly or indirectly to the application device.

2. The system as claimed in claim 1 , wherein a terminal module is provided for each application device.

3. The system as claimed in claim 1 , wherein the terminal device comprises at least one color changer.

4. The system as claimed in claim 1 , wherein the terminal device comprises at least one pigging station.

5. The system as claimed in claim 1 , wherein the at least one factory-prefabricated terminal module comprises a gas-tight housing.

6. The system as claimed in claim 5 , wherein the gas-tight housing includes a collecting trough, the collecting trough being positioned below the branch lines and inclined towards one side of the collecting trough.

7. The system of claim 6 , wherein the gas-tight housing comprises an outlet, the outlet being located in the housing proximate a lowest portion of the collecting trough to facilitate removal of liquids collected in the collecting trough from the housing.

8. The system as claimed in claim 5 , wherein the gas-tight housing of the at least one factory-prefabricated terminal module has a viewing window.

9. The system as claimed in claim 1 , in which at least one catwalk that can be entered by operating personnel is provided along the painting booth, wherein the at least one factory-prefabricated terminal module is fitted above the catwalk.

10. The system as claimed in claim 1 , in which at least one catwalk that can be entered by operating personnel is provided along the painting booth, wherein the at least one factory-prefabricated terminal module is fitted underneath the catwalk.

11. The system as claimed in claim 10 , wherein the catwalk has a window above the at least one factory-prefabricated terminal module.

12. The system as claimed in claim 1 , wherein the operating mediums is a paint of a specific color or a purging liquid or air.

13. The system of claim 1 , wherein each first terminal is located on a first side of the at least one factory-prefabricated terminal module and each second terminal is located on a second side of the at least one factory-prefabricated terminal module, wherein the second side is opposite the first side on the at least one factory-prefabricated terminal module.
