Description

The invention relates to a printing machine with a non-impact printing unit and a creasing device according to the preamble of claim 1.

To produce packaging for pourable food products, web-like substrates are typically first printed and often later provided with additional functional layers. These substrates are typically provided with a creasing pattern after printing to facilitate subsequent completion of packaging containers. Holes for drinking straws, for example, are also typically punched at this time. This completion is preferably carried out in combination with a filling process. To achieve a stable creasing pattern, it is common practice to first apply the desired print image using a form-based printing process and then create the creasing pattern. This ensures that the creasing pattern is retained in its original form.

In the flexographic printing process, drying typically occurs after each of, say, four printing processes of individual colors. These individual colors, for example, have a water content of approximately 60%, which must be removed during drying.

There are efforts to perform the printing process entirely or partially using non-impact printing methods, for example, to produce short runs or customized print images cost-effectively. For example, flexo printing units are being replaced with a non-impact printing unit.

Through the WO 01/51275 A1 and the US 2006/0032928 A1 It is known to print a web-shaped substrate in a printing gap between rotating bodies and then to provide it with a creasing pattern.

Through the EP 3 738 780 A1 It is known to print a web-shaped packaging material before filling using an inkjet printing process instead of a flexographic printing process.

Through the WO 2019/007979 A1 It is known to print a web using inkjet printing and then to provide it with a creasing pattern.

Through the EP 3 369 572 A1 A sheet-fed printing machine is known in which a flexographic printing unit, an inkjet printing unit and a creasing device are arranged one after the other along a transport path provided for transporting substrate.

The invention is based on the object of creating a printing machine with a non-impact printing unit and a creasing device.

The object is achieved according to the invention by the features of claim 1.

A printing press is assigned a transport path provided for transporting substrate. The printing press has at least one non-impact printing unit with at least one print head. The printing press has at least one drying device which is assigned to this non-impact printing unit and whose area of action is arranged along the transport path provided for transporting substrate after one and preferably after each application area of this non-impact printing unit. The printing press has at least one creasing and/or punching device, in particular with at least one creasing tool and/or at least one punching tool. Preferably, the at least one creasing and/or punching device is designed at least as a creasing device. A processing point of the at least one creasing and/or punching device is arranged along the transport path provided for transporting substrate before the application area of this non-impact printing unit and/or before the area of action of the drying device assigned to this non-impact printing unit. Further preferably, the processing point of the at least one creasing and/or punching device is arranged along the transport path provided for the transport of substrate upstream of the action area of the drying device assigned to this non-impact printing unit and even more preferably, the processing point of the at least one creasing and/or punching device is arranged along the transport path provided for the transport of substrate also upstream of and more preferably upstream of each application area of the non-impact printing unit.

This results in the particular advantage that creasing and/or punching of the substrate takes place before this drying device acts on the substrate. In non-impact printing and especially in inkjet printing, four colors are usually printed one after the other on the substrate and only then is the entire printed image dried. In inkjet printing in particular, the respective colors usually have a moisture content of around 80%. Depending on the printed image, total moisture levels of up to 320% can occur in some surface areas before drying takes place. Since in the described arrangement, drying only takes place after However, when the creasing occurs before the creasing is introduced, the printed image can be dried particularly intensively. Areas of the substrate that have been coated with relatively little ink and therefore relatively little moisture can become relatively brittle and fragile at high dryer power levels. However, because the substrate is only dried to this extent after creasing or punching, the creasing or punching has no negative impact on the creasing or punching result, even with high dryer power and low initial moisture levels. The substrate can therefore be printed on any large area with high moisture content and then dried accordingly and still be further processed into tight, high-quality packaging. Creasing before a printing process in the same area of the substrate is possible with the non-impact printing process because pre-creased substrate is not pressed into a printing nip by the printing process and the creasing is therefore retained. In addition, it is possible to use relatively short drying devices with relatively high temperatures. This saves installation space and costs compared to long dryers with low temperatures.

In a further development, the printing press is preferably characterized in that the at least one drying device is designed as a hot-air drying device and/or as an infrared drying device. This infrared drying device preferably has at least one radiation source for the targeted emission of electromagnetic radiation in the near-infrared range, i.e., with a wavelength between 780 nm and 3 µm. These are particularly effective when using water-based inks, which is particularly advantageous in the food industry. In particular, the introduced moisture is preferably heated or dried, rather than the substrate itself.

In an alternative or additional development, the printing press is preferably characterized in that the printing press has at least one upstream, form-bound printing unit, the application area of which is arranged along the transport path provided for the substrate transport, upstream of the processing point of the creasing and/or punching device. This at least one upstream form-bound printing unit is preferably designed as a flexographic printing unit. This allows consistent print images and/or primers for non-impact printing to be produced cost-effectively without affecting the creasing.

In an alternative or additional development, the printing press is preferably characterized in that the printing press has at least one downstream form-bound printing unit, the application area of which is arranged along the transport path provided for the transport of substrate after the or each application area of the non-impact printing unit and/or after the exposure area of the drying device assigned to the non-impact printing unit. This at least one downstream form-bound printing unit is preferably designed as a flexographic printing unit. This allows consistent print images to be produced cost-effectively in the area outside the creases without affecting the creases.

In an alternative or additional development, the printing press is preferably characterized in that a machine control system of the printing press is configured to take into account the detection of at least one creasing and/or punching mark, generated in particular by means of the at least one creasing and/or punching device, when controlling the at least one non-impact printing unit. Thus, register accuracy between non-impact printing and creasing can be ensured.

In an alternative or additional development, the printing press is preferably characterized in that the at least one non-impact printing unit is designed as an inkjet printing unit and/or that the at least one print head is designed as an inkjet print head. This allows for particularly high print quality at low cost.

In an alternative or additional development, the printing press is preferably characterized in that the at least one non-impact printing unit has at least one print head unit, the application area of which extends, in particular, continuously over a width of at least 20 cm, more preferably at least 50 cm, even more preferably at least 100 cm, even more preferably at least 150 cm, and even more preferably at least 200 cm in a transverse direction. This allows a non-impact print image to be produced at any point on the substrate and thus a particularly high-quality printed product.

In an alternative or additional development, the printing machine is preferably characterized in that the at least one non-impact printing unit has at least two, more preferably at least three, and even more preferably at least four print head units, whose application areas are arranged one after the other along the transport path provided for the transport of substrate. These are more preferably each connected to their own supplies, which are in particular completely separate from one another with regard to liquid lines. This allows for multiple Non-impact printing and therefore a high-quality printed product.

In an alternative or additional development, the printing press is preferably characterized in that the printing press is designed as a web-fed printing press and/or has at least one substrate feed device designed as a roll unwinding device and in particular as a roll changer and/or at least one winding device for winding printed and grooved substrate. This enables particularly high printing speeds and further processing in conventional filling systems.

In an alternative or additional development, the printing press is preferably characterized in that the printing press has at least one inspection device arranged in alignment with an inspection point of the transport path provided for the transport of substrate. The inspection point is preferably arranged along the transport path provided for the transport of substrate after the or each application area of the non-impact printing unit and more preferably after the or each application area of the at least one downstream form-based printing unit. This allows the quality of the substrate processing to be checked and the printing press to be adjusted if necessary.
