Device for imaging and/or varnishing the surfaces of objects
A device for imaging and/or varnishing the surfaces of objects or vehicles, etc. includes adapting a time lag between an application of fluid and further treatment thereof, such as drying ink or varnish, to a spreading behavior of the fluid during the application thereof. The fluid may be applied to the surface of the object in sections, firstly drying the fluid in individual sections before applying it to the next section.
1. A device for treating surfaces of objects, including vehicles, with fluids, the device comprising:
a robot arm having an end;
a removable receiving element supported on said end of said robot arm, said removable receiving element being a revolving head having an axis of rotation implemented by an existing robot axis or by a virtual axis created from movements about multiple axes;
a print head attached to said revolving head and configured to apply a fluid to the object in an operating position;
a radiation source attached to said revolving head and configured to further treat the fluid in said operating position subsequent to application;
said revolving head alternately moving said print head and said radiation source into said operating position;
a control computer operating one path control or simultaneously operating two path controls for said print head and said radiation source and said control computer moving said print head and said radiation source into operating positions in accordance with a rhythm adapted to a spreading time of ink; and
a memory storing said path or paths to be controlled and storing displacement speeds to provide a time lag between applying the fluid and subsequently further treating the fluid, said time lag being adapted to a spreading behavior of the fluid for locations being successively passed by said print head and said radiation source.
2. The device according to claim 1 , wherein said revolving head additionally carries and moves at least one of a tool for pretreating the surface to be imaged or further ink print heads into said operating position.
3. The device according to claim 1 , wherein said robot arm is an articulated arm robot.
