Description
Technical Field
In printing objects, it is often necessary to reliably fix (e.g. harden) the printed image, since the printing result is partially subjected to great stress during its subsequent intended use. This can be achieved, for example, by using UV-curable inks. In order to fix the UV-curing ink on the object, a corresponding device for curing the ink and further processing steps are required. If the ink is only partially hardened, it is called nailing (pinner).
Background
EP 2152519B 1 discloses an apparatus for printing containers. The containers are moved on the endless track and are simultaneously printed by a printing head which is moved together on the endless track and is additionally movable relative to the containers. Each print head is provided with a drying device which moves together on an endless track. For drying, the container is rotated relative to the drying device about its own vertical axis.
DE 102015203798 a1 discloses a device for printing three-dimensional objects. Here, a plurality of fixed-point inkjet print heads are used. Each printing head is provided with a drying device which is fixed in the same place. The device also has a rotatable and pivotable gripper device which moves the printing object past the printing head and the dryer.
Disclosure of Invention
The object of the present invention is to provide an improved device for printing (three-dimensional) objects compared to the prior art, which device enables good printing results with a small number of components.
This object is achieved by a device having the features of the invention.
The apparatus for printing an object according to the present invention includes: (at least one) printing device (such as an inkjet print head) which is arranged stationary in place during printing; means for moving an object into a region of action of the printing means; and a device for treating the object (such as a UV stapling module). The invention is characterized in that the device for processing objects is arranged on the device for moving objects.
Advantageously, such a device requires only one means for processing (objects) to be sufficient. The latter (the means for processing the object) is preferably guided together with the object and is therefore always in the processing position.
According to a first further development of the invention, provision is made for: the device for processing objects is arranged on the device for moving objects by means of an adjustable suspension. The necessary adaptation of the spacing and/or angular position in the case of an object/object shape/object size transformation is thus achieved.
The invention further provides that: the distance of the device for processing an object to the object and/or the angle of inclination relative to the (active) printing device can be varied by means of the adjustable suspension.
In accordance with another embodiment of the present invention, an adjustable hanger has a multi-articulated hanger
The multi-articulated hanger is rotatably secured to the device for moving objects. Preferably, one rotary hinge for fastening to the robot and two orthogonal sliding hinges are provided.
In a particularly advantageous embodiment of the invention, the device for treating the object is a UV-curing module for curing the ink applied by the printing device on the object within a predetermined time window. However, complete drying may also be carried out.
Can also be provided with a device for applying varnish to the printed object
As a processing means (in place of or in addition to the stapling module/drying module).
Another embodiment of the present invention provides: the device for moving the object relates to a robot arm which rotates the object about a (e.g. horizontal) axis of the object and/or about a (e.g. vertical) axis of the robot arm. The robot may also effect height adjustment and/or radial adjustment of the object.
The invention further provides that: the adjustable suspension has a drive on each of its articulations, wherein these drives can be controlled by a machine controller. A common drive is also possible. Preferably a linear actuator.
Particularly advantageous embodiments are: the means for processing objects are controlled by the machine controller depending on the angular velocity at which the means for moving objects rotate the objects around their own axis and/or depending on the distance of the means for processing objects to the (active) printing means and/or to the objects.
In addition, the expansion scheme of the invention is as follows: a shielding (blend) is mounted on the stapling module to prevent emission (scattering) of UV radiation. Preferably, the shielding can be adapted to different objects by adjustment or replacement.

Detailed Description
Fig. 1 schematically shows a partial view of a printing press 1 suitable for printing a three-dimensional object 2. It can be seen that: six inkjet printing devices 3, a robot arm 11 on which the spherical printing objects 2 are mounted, and a UV stapling module 5 fastened to the robot arm by means of a multi-articulated-joint hanger 6.
The object 2 is rotated by the robot arm 11 at an angular velocity of, for example, 90 °/s, below the stationary first printing device 3 by means of a drive about the horizontal axis 14 of the object 2 itself. In this case, the multi-articulated suspension 6 is set in such a way that the stapling module 5 is oriented at an angle of 90 ° relative to the printing couple 3. After the first printing device 3 has applied the ink 12 to the object, the stapling module 5 is (in the example mentioned) activated by the machine controller 9 and preferably irradiates the printed image 13 with radiation. In this case, the shielding 10 on the stapling module 5 prevents undesirable emission of UV radiation. After the first printing device 3 has finished the printing process, the stapling module 5 is deactivated (in the example mentioned) by the machine controller 9. The robot arm 11 is rotated together with the object 2 about the vertical axis 15 of the robot arm 11, so that the object 2 enters the region of action of the stationary second printing group 3 and the printing process and the stapling process are repeated in the manner described (so-called transfer). Drying or stapling can also be carried out by means of the apparatus according to the invention during the transfer of the objects (movement to the next print head).
Fig. 2 shows a partial view (from above) of a printing machine 1 suitable for printing a three-dimensional object 2. It can be seen that: an inkjet printing device 3, a robot arm 11 on which the spherical printing object 2 is mounted, and a stapling module 5 fastened on the robot arm by means of a multi-articulated-portion hanger 6.
The multi-articulated hanger 6 has a drive 8 on its articulation 7. The drives 8 can be controlled by the machine controller 9 in such a way that the setting can be set arbitrarily, irrespective of the distance a of the stapling module 5 from the object 2 or the angle α of the stapling module 5 relative to the printing group 3 or relative to the object 2 (individually).
The printing press 1 is set up ready for printing spherical objects 2, for example, with a radius of 15cm and is operated at an angular speed of, for example, 90 °/s. Correspondingly, the multi-articulated hanger 6 is set such that the stapling module 5 is located, for example, approximately 16cm from the center point of the object 2 and, for example, at an angle α of 90 ° relative to the printing unit 3. After finishing the processing of this first object 2, a second spherical object 2 with a radius of e.g. 23cm may be printed. Special requirements for the surface of the second object 2 are, for example, to reduce the angular velocity to, for example, 45 °/s, in order to be able to continue to achieve an optimum printing result. The machine controller 9 is supplied with corresponding data and actuates the drive 8 of the articulation 7 of the suspension 6 in such a way that the stapling modules 5 are arranged at a distance of 24cm from the center point of the object 2 and at an angle of 45 ° relative to the printing unit 3. The fastener 16 can be rotated about the horizontal axis 14 for this purpose.
The positioning of the module 5 may be performed at the factory by means of a multi-articulated hanger 6 and/or the settings may be adjusted (automatically or manually) by the operator on site for the object/object size in the transformation.
In the case of small objects 2, the 90 ° positioning of the modules 5 also has the additional advantage that the radiation traveling through the object is not directed towards the print head, and therefore the ink does not dry out on the print head (anticocknen).
Alternatively, the stapling module 5 can also be arranged in other angular positions (with reference to the object) relative to the printing device 3, preferably 180 °, i.e. the object is located between the printing device and the stapling module.
The angular positioning of the module 5 can also be used to guide the module 5 to a rest position (where collision with the print head is avoided).
