Abstract

A changing device for coating media, including supply units that each have at least one inlet connection connectable to a reservoir, and an outlet connection, between which a flow channel extends. A coupling unit has an input connection and an output connection, connectable to an application device, between which input connection and output connection a through-channel extends. The coupling unit is movable in a positioning movement direction relative to the supply units by a positioning device. The input connection of the coupling unit is complementary to the outlet connections of the supply units so that the input connection of the coupling unit is movable in a coupling movement direction relative to one of the supply units and can be coupled to or disconnected from the outlet of the supply unit. The positioning device only moves the coupling unit in a plane in which the coupling movement direction also lies.

First claim

1 - 10 . (canceled)

11 . A changing device for coating-media, in particular for lacquers, with
a) several supply units, each of which exhibits at least one inlet port, which can be connected to a reservoir, and an outlet port, between which a flow channel extends; b) at least one coupling unit which exhibits an input port and an output port which can be connected to an application device, between which a through-channel extends; c) a positioning device, by means of which the coupling unit can be moved relative to the supply units in at least one positioning-motion direction; wherein d) the input port of the coupling unit is complementary to the outlet ports of the supply units in such a manner that the input port of the coupling unit can be moved relative to one of the supply units in a coupling-motion direction and can be coupled with the outlet of this supply unit and separated again from the latter, wherein e) the positioning-motion device has been set up in such a way that the coupling unit can be moved only in a plane in which coupling-motion direction also lies.

12 . The changing device according to claim 11 , wherein the coupling unit can be moved in positioning-motion direction on a linear path of motion.

13 . The changing device according to claim 11 , wherein the coupling unit can be moved in positioning-motion direction on at least one portion of a circular path.

14 . The changing device according to claim 11 , wherein the positioning-motion direction has been set up in such a way that positioning-motion direction is a first positioning-motion direction, and the coupling unit can be moved by the positioning device, in addition, in a second positioning-motion direction with a motion component that is perpendicular to the first positioning-motion direction, the two positioning-motion directions and of the coupling unit and the coupling-motion direction lying in the common plane.

15 . The changing device according to claim 11 , wherein the coupling unit has been supported so as to be mobile in one or more guide rails and/or on a rotary element.

16 . The changing device according to claim 11 , wherein the supply units have been encompassed by a linear supply module in which the supply units have been arranged linearly and all the outlet ports point in the same direction,

17 . The changing device according to claim 16 , wherein several linear supply modules have been arranged in a plane, the axes of the outlet ports of the supply units of all the supply modules lying in this plane,

18 . The changing device according to claim 11 , wherein the supply units have been encompassed by a supply drum in which the supply units have been arranged in the form of a circle in a plane, and all the outlet ports point in a radial direction with respect to the midpoint of the supply drum.

19 . The changing device according to claim 18 , wherein several supply drums with different diameters have been arranged coaxially in relation to one another and in a plane.

20 . A coating system for coating objects, with:
a) an application device; b) several reservoirs for a respective coating-medium; c) at least one changing device with several inlet ports, each of which has been connected to its own reservoir for coating-medium, and
