Abstract

Claims (50)

1 . A change system for changing a mixer, comprising:

a mixing device, having the mixer, for mixing at least two different components for a multi-component application agent for application onto a workpiece, and

a handling device for moving the mixing device,

wherein

the change system comprises a change station for depositing the mixing device with the mixer to be changed and for receiving a new mixing device with a new mixer,

wherein the mixing device and/or a change insert comprises at least two separate lines to guide the at least two different components separately from each other,

wherein the at least two separate lines

comprises passage cross-sections tapering towards the mixer, and/or

extend parallel and/or at an acute angle to one another, and

wherein the change insert comprises a tapered section tapering towards the mixer and the at least two separate lines open out via at least two outlet openings in the tapered section.

2 . The change system according to claim 1 , wherein the change station is arranged within reach of the handling device and the handling device is configured to position in an automated manner in the change station the mixing device with the mixer to be changed and to receive, in an automated manner, the new mixing device with the new mixer out of the change station.

3 . The change system according to claim 1 , wherein the handling device is arranged in an application cell, and

the change station is arranged at least partially within the application cell,

the change station is arranged at least partially outside the application cell, and/or

the change station is movable in order to move at least partially into the application cell and at least partially out of the application cell.

4 . The change system according to claim 3 wherein the change station comprises at least two receivers including one receiver for the mixing device with the mixer to be changed and at least one receiver for at least the new mixing device with the new mixer.

5 . The change system according to claim 4 , wherein a contour of the receivers corresponds to a contour of the mixing device, such that the mixing device is fixable relative to its circumferential direction.

6 . The change system according to claim 1 wherein the change station comprises a turntable.

7 . The change system according to claim 1 , wherein the at least two separate lines extend at least up to the mixer.

8 . The change system according to claim 7 , wherein the tapered section

protrudes from a base section of the mixing device,

projects into an application tube of the mixing device, and/or

is partially exposed in the mixing device.

9 . The change system according to claim 8 , wherein the mixing device comprises a conical connecting surface for releasable connection to the tapered section.

10 . The change system according to claim 9 , wherein the tapered section and the connecting surface have an identical angular position in their contact area.

11 . The change system according to claim 10 , wherein the tapered section is tightly and/or prestressably connectable to the connecting surface.

12 . The change system according to claim 1 wherein the handling device carries an application head for supplying the at least two different components to the mixing device and the mixing device comprises an interface for releasable connection to the application head.

13 . The change system according to claim 12 , wherein the handling device is configured

to position in the change station the mixing device with the mixer to be changed and to move the application head, such that the interface is released and the mixing device with the mixer to be changed can be deposited in the change station, and/or

to move the application head, such that the interface is closed and the new mixing device with the new mixer can be removed out of the change station.

14 . The change system according to claim 1 wherein the mixing device comprises a base section and an application tube, wherein the mixer is accommodated in the application tube and/or the base section comprises an interface for releasable connection to an application head of the handling device.

15 . The change system according to claim 14 , wherein the change insert

is insertable in a releasable manner into the mixing device and/or into the application head, and/or

extends through the interface.

16 . The change system according to claim 15 , wherein the change insert comprises a cylindrical basic structure with different outer diameters for accurately fitting and/or dead space free insertion in the mixing device and/or in the application head.

17 . The change system according to claim 16 , wherein the change insert comprises at least one fastening recess in its lateral surface and at least one pluggable retaining element is provided in order to fasten in a releasable manner the change insert by means of the at least one fastening recess.

18 . The change system according to claim 17 , wherein the application head comprises at least one fastening opening and the at least one retaining element is configured for engagement with the at least one fastening recess and with the at least one fastening opening.

19 . The change system according to claim 18 , wherein the at least one retaining element is engageable with the change insert from outside through the application head and comprises at least one bolt or bracket for insertion into and withdrawal from the at least one fastening recess and the at least one fastening opening.

20 . The change system according to claim 1 wherein the handling device comprises a robot having at least 3 degrees of freedom.

21 . A change system for changing a mixer, comprising:

a mixing device, having the mixer, for mixing at least two different components for a multi-component application agent for application onto a workpiece, and

a handling device for moving the mixing device,

wherein

the change system comprises a change station for depositing the mixing device with the mixer to be changed and for receiving a new mixing device with a new mixer,

wherein the mixing device comprises a base section and an application tube, wherein the mixer is accommodated in the application tube and/or the base section comprises an interface for releasable connection to an application head of the handling device,

wherein a change insert

is insertable in a releasable manner into the mixing device and/or into the application head, and/or

extends through the interface,

wherein the change insert comprises a cylindrical basic structure with different outer diameters for accurately fitting and/or dead space free insertion in the mixing device and/or in the application head, and

wherein the change insert comprises at least one fastening recess in its lateral surface and at least one pluggable retaining element is provided in order to fasten in a releasable manner the change insert by means of the at least one fastening recess.
