Abstract

A device for printing on multi-dimensional objects includes an object carrier for holding and moving the object to be printed on, a tool carrier for receiving stationary processing tools, and a frame to which the tool carrier is fixed. The object carrier has three guide tracks which are disposed perpendicular to one another and each of which is oriented along a respective axis of movement. Carriages are movable on the guide tracks for executing a translatory movement of the object relative to the stationary processing tools. The device may have a modular construction, allowing the device to be adapted to a variety of objects to be printed on.

First claim

The invention claimed is:

1. A device for printing on multidimensional objects, the device comprising:
a frame;
stationary processing tools;
a tool carrier for receiving said stationary processing tools, said tool carrier being fixed to said frame;
an object carrier for holding and moving an object to be printed on, said object carrier having three guide tracks being oriented perpendicularly to one another, each of said three guide tracks being oriented along a respective one of three axes of movement and said three guide tracks including a third guide track;
said three axes of movement including first, second and third axes of movement, said object carrier having first, second and third axes of rotation for rotating the object, said first axis of rotation being oriented parallel to said first axis of movement, said second axis of rotation being oriented parallel to said second axis of movement and said third axis of rotation being oriented parallel to said third axis of movement;
two right-angled arms, said first axis of rotation being disposed on said third guide track, said second axis of rotation being disposed on said first axis of rotation through one of said right-angled arms and said third axis of rotation being fixed to said second axis of rotation through the other of said right-angled arms; and
carriages each being movable on a respective one of said three guide tracks for carrying out a translatory movement of the object relative to said stationary processing tools.

2. The printing device according to claim 1 , wherein said three guide tracks include a first guide track having two guide rails oriented parallel to one another.

3. The printing device according to claim 2 , wherein said two guide rails are two horizontal guide rails.

4. The printing device according to claim 2 , which further comprises a foundation or base plate, and two side walls to be elevated over said foundation or base plate, each of said two guide rails being disposed on a respective one of said side walls.

5. The printing device according to claim 4 , wherein said two side walls are interconnected, forming arms of a U profile.

6. The printing device according to claim 5 , wherein said U profile extends beyond said frame.

7. The printing device according to claim 6 , wherein said U profile is formed of three elements of identical construction.

8. The printing device according to claim 2 , wherein said first guide track is constructed as a gantry carriage with a gantry drive.

9. The printing device according to claim 1 , wherein at least one of said processing tools is at least one print head.

10. The printing device according to claim 9 , wherein said at least one print head is at least one inkjet print head.

11. The printing device according to claim 1 , wherein said frame has substantially vertical supports, and said tool carrier is adjustable in height and movable along said substantially vertical supports.

12. The printing device according to claim 1 , wherein said tool carrier has recesses formed therein, and each of said processing tools is mountable in a respective one of said recesses in two alternative positions being rotated through 90° relative to one another.
