Abstract

A multi-application module (1), a multi-application device (2) and a working method for a multi-application device (2). The multi-application module (1) for printing on a substrate (6) or a transfer product (7) includes a printing unit (8) and a multifunctional element (9), wherein a printing nip (10) is formed between the printing unit (8) and the multifunctional element (9), and wherein the multifunctional element (9) has a first multifunctional roller (91) and/or at least one second multifunctional roller (92) and/or a printing table (13), and wherein the printing unit (8) is designed such that it can print along two running directions in the printing nip (10).

First claim

1 . A multi-application module for printing on a substrate or a transfer product, comprising a printing unit and a multifunctional element, wherein a printing nip is formed between the printing unit and the multifunctional element, and
wherein the multifunctional element has a first multifunctional roller and/or at least one second multifunctional roller and/or a printing table,
and wherein the printing unit is designed such that it can print along two running directions in the printing nip,
and wherein the printing unit is or comprises a UV inkjet printbar and/or wherein the printing unit comprises at least one inkjet printhead,

and wherein the printing on the substrate or on the transfer product is effected with the same printing unit in the same printing nip,
and wherein, if the first multifunctional roller and/or the at least one second multifunctional roller is rotated in a first rotational direction, the substrate guided on the first multifunctional roller and/or the at least one second multifunctional roller can be printed on in the printing nip, in a first running direction, or wherein, if the first multifunctional roller and/or the at least one second multifunctional roller is rotated in a second rotational direction, opposing the first rotational direction, the transfer product guided on the first multifunctional roller and/or the at least one second multifunctional roller can be printed on in the printing nip, in a second running direction, opposing the first direction.

2 . The multi-application module according to claim 1 , wherein the multi-application module further has two winding rollers for receiving the transfer product.

3 . The multi-application module according to claim 1 , wherein
the multi-application module further has a clamping system for clamping the transfer product, wherein the clamping system has one or more of the following elements, selected individually or in combination from: dancer roller, controlled dancer roller, measuring roller, friction shaft.

4 . The multi-application module according to claim 1 , wherein
the first multifunctional roller and/or the at least one second multifunctional roller is mounted rotatable in two opposing rotational directions.

5 . The multi-application module according to claim 1 , wherein
the first multifunctional roller in combination with a second multifunctional roller and/or the first multifunctional roller in combination with two second multifunctional rollers and/or two second multifunctional rollers are arranged such that the substrate or the transfer product can be guided via the first multifunctional roller and/or the at least one second multifunctional roller and thereby forms a flat printing surface.

6 . The multi-application module according to claim 5 , wherein
the flat printing surface is arranged perpendicular to the printing unit and/or forms a surface area with a size of between 250 mm 2 and 1,000,000 mm 2 .

7 . The multi-application module according to claim 1 , wherein
the printing table is arranged such that the substrate or the transfer product can be guided over the printing table.

8 . The multi-application module according to claim 1 , wherein
the printing table forms a flat surface area, and/or wherein the printing table is arranged perpendicular to the printing unit.

9 . The multi-application module according to claim 1 , wherein
the printing table has air outlets for generating an air cushion.

10 . The multi-application module according to claim 1 , wherein
the multi-application module further has at least one UV precuring light source.

11 . The multi-application module according to 10 , wherein
the at least one UV precuring light source generates an irradiance of between 0 W/cm 2 and 10 W/cm 2 .

12 . The multi-application module according to claim 1 , wherein
the surface of the first multifunctional roller and/or of the at least one second multifunctional roller has a surface structure generated by a surface finishing process and/or wherein the first multifunctional roller and/or the at least one second multifunctional roller has an anti-slip coating and/or a traction coating.

13 . The multi-application module according to claim 1 , wherein
the printing unit and/or the UV inkjet printbar has at least two rows of printheads and/or wherein the printing unit has at least two ink receiving devices for receiving at least two different inks.

14 . The multi-application module according to claim 6 , wherein
ink is ejected from the printing unit perpendicularly, relative to the surface of the multifunctional element.

15 . The multi-application module according to claim 1 , wherein
the substrate or the transfer product can be guided by means of the first multifunctional roller and/or the at least one second multifunctional roller and/or wherein the first multifunctional roller and/or the at least one second multifunctional roller is formed for guiding the substrate or the transfer product.

16 . The multi-application module according to claim 1 , wherein
the substrate guided on the first multifunctional roller and/or the at least one second multifunctional roller or the transfer product guided on the first multifunctional roller and/or the at least one second multifunctional roller can be printed on along the two running directions in the printing nip by means of the printing unit.

17 . The multi-application module according to claim 1 , wherein
the substrate or the transfer product is guided on the same first multifunctional roller and/or at least one second multifunctional roller.

18 . The multi-application module according to claim 1 , wherein
the multi-application module has a changeable substrate path and/or transfer product path.

19 . The multi-application module according to claim 1 , wherein
the multi-application module comprises at least one detection unit, which detects the position of at least one element and/or at least one layer on the substrate and/or the transfer product, wherein the detection unit is connected to a control device, which controls the printing unit on the basis of the position data detected by the detection unit such that the printing on the substrate and/or the transfer product is effected in register with the at least one element and/or the at least one layer.

20 . A multi-application device comprising a multi-application module according to claim 1 and a cold transfer unit, wherein the cold transfer unit comprises a pressure roller and a counter-pressure roller.

21 . The multi-application device according to claim 20 , wherein
