Abstract

A machine arrangement, that sequentially processes sheet-type substrates, includes a plurality of different processing stations, one of which includes a non-impact printing device that prints the substrates. Further processing stations are a primer application device that primes the substrates and a dryer for drying the primer applied to the substrates. The primer application device and the dryer precede the non-impact printing device, in the direction of travel of the substrates. The processing station including the non-impact printing device, also includes a printing cylinder, on the circumference of which, the non-impact printing device that prints the substrates is arranged.

First claim

The invention claimed is:

1. A machine arrangement for the sequential processing of sheet-type substrates, comprising a plurality of processing stations, wherein a first one of the plurality of the processing stations includes a non-impact printing unit for printing each of the sheet-type substrates, wherein a primer application unit for priming each of the sheet-type substrates and a first dryer for drying the primer applied to each of the sheet-type substrates are provided as additional ones of the plurality of processing stations, wherein the primer application unit and the first dryer are each arranged upstream of the non-impact printing unit in a transport direction of the sheet-type substrates, wherein the first one of the plurality of processing stations that comprises the non-impact printing unit includes a printing cylinder, wherein the non-impact printing unit for printing each of the sheet-type substrates is located on the periphery of the printing cylinder, wherein, downstream of the first one of the plurality of processing stations that comprises the non-impact printing unit for printing the substrates, in the transport direction of the sheet-type substrates, a second one of the plurality of processing stations is provided, and having a second dryer for drying the sheet-type substrates that have been printed by the non-impact printing unit, wherein downstream of the second one of the plurality of processing stations that comprises the second dryer for drying the printed sheet-type substrates, in the transport direction of the sheet-type substrates, a third one of the plurality of processing stations, and having a coating unit is provided, and downstream of the coating unit, a fourth one of the plurality of processing stations having a third dryer is provided, wherein the printing cylinder is embodied as one of triple-size and quadruple-sized, whereby one of three and four of the sheet-type substrates one of are and can be arranged, one behind the other, in a circumferential direction, on a circumferential surface of the printing cylinder, wherein each of the sheet-type substrates to be transported is held on the circumferential surface of the printing cylinder, in one of a force-locking manner by suction air and in a form-fitting manner by at least one gripper, and wherein the one of the primer and the coating material are applied to at least pre-selected areas of the surface of each of the sheet-type substrates, which pre-selected areas are less than an entire surface of the each of the sheet-type substrates.

2. The machine arrangement according to claim 1 , wherein at least one of the first dryer for drying the primer that is applied to the sheet-type substrates, and the second dryer for drying the sheet-type substrates printed by the non-impact printing unit, and the third additional dryer is embodied as a dryer for drying each of the one of the primed and printed and coated sheet-type substrates using one of hot air and by irradiation with one of infrared and ultraviolet radiation.

3. The machine arrangement according to claim 2 , wherein the at least one of the first, second and third dryers for drying each of the sheet-type substrates by irradiation with one infrared and ultraviolet radiation is embodied as an LED dryer.

4. The machine arrangement according to claim 1 , wherein the non-impact printing unit for printing the sheet-type substrates comprises one of four and five and six and seven inkjet printing units, each inkjet printing unit being controlled individually, and wherein these inkjet printing units are arranged one behind the other in the transport direction of the sheet-type substrates.

5. The machine arrangement according to claim 1 , wherein the non-impact printing unit for printing the sheet-type substrates is configured such that it is able to print each of the sheet-type substrates at least nearly over an entire width of each of the sheet-type substrates, oriented transversely to the transport direction.

6. The machine arrangement according to claim 1 , wherein the one of the plurality of processing stations that comprises the primer application unit includes a printing couple cylinder, which printing couple cylinder cooperates with an impression cylinder and has a forme roller in the form of an anilox roller, which anilox roller one of is and can be thrown onto the printing couple cylinder, and which anilox roller also includes one of at least one doctor blade that extends in an axial direction of the forme roller and an ink chamber blade system.

7. The machine arrangement according to claim 1 , wherein at least those ones of the plurality of processing stations that comprise one of the non-impact printing unit and the primer application unit and the first dryer situated downstream of the primer application unit and each one of the plurality of processing stations are each arranged in their own frame as one of a separately installed machine unit and a functional subassembly.

8. The machine arrangement according to claim 1 , wherein a transport module, formed as a sheet-type substrate guide unit, with no sheet-type substrate processing unit, is situated one of immediately upstream and downstream of the first one of the plurality of processing stations that includes the printing cylinder assigned to the non-impact printing unit for printing the sheet-type substrates.

9. The machine arrangement according to claim 1 , wherein the ones of the plurality of processing stations that comprise one of the printing unit and one of the first, second and third dryers and the coating unit each include a transport apparatus having a plurality of transport units arranged one behind the other in the transport direction of the sheet-type substrates and with each transport unit having at least one transport cylinder.

10. The machine arrangement according to claim 1 , wherein one of the primer application unit is configured to apply the primer to the sheet-type substrates over the entire surface of the sheet-type substrates and the coating unit is configured to apply the coating to the sheet-type substrates over the entire surface area of the sheet-type substrates.

11. The machine arrangement according to claim 1 , wherein the sheet-type substrates are each made of one of a paper and of a single-layer paperboard and of a multi-layer paperboard and of a cardboard.

12. The machine arrangement according to claim 1 , wherein the machine arrangement is configured for processing each of the sheet-type substrates to produce packaging means.
