Description

The invention relates to an inspection unit with a rotating transport body.

It is known to apply coating agents with magnetic or magnetizable particles to substrate and then to align the particles using an alignment device that works, for example, with magnetic fields. In this way, optical effects that depend on the viewing angle can be created, which can be fixed by curing the coating agent.

Through the WO 2021/259527 A1 a method is known in which a layer of a crosslinkable coating agent with magnetic or magnetizable particles is applied to a substrate using a screen printing process and these particles are oriented parallel to one another using an alignment device, with a further layer then being applied using an inkjet printing device and the parallel one Orientation of these particles is partially canceled again and the layer of the coating agent is then crosslinked by means of radiation.

Through the WO 2020/148076 A1 It is known to apply and align coating agents with magnetic or magnetizable particles to a substrate and to specifically harden them using a matrix of individually controllable UV LEDs in order to produce a motif.

Through the EP 2 007 581 B1 a printing machine is known which has an inkjet printing device in front of a screen printing device.

Through the EP 2 084 005 B1 a method is known in which a crosslinkable substance is applied to a substrate using an inkjet printing device and then cured using UV radiation.

The invention is based on the object of creating an inspection unit with a rotating transport body.

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

A printing unit preferably has at least one first form-bound printing point, which is formed by a pair of interacting rotating bodies, the printing unit having at least one first alignment cylinder along a transport path provided for transporting substrate after the first form-bound printing point and the printing unit along the for Transport of substrate provided transport path after the first form-bound printing point has at least one first non-impact printing point, to which at least one first print head is assigned and wherein the printing unit along the transport path provided for the transport of substrate after the first non-impact printing point has at least a first curing device with a has the first curing area assigned to this. In a further development, the printing unit is preferably characterized in that in the area of the first non-impact printing point, the transport path provided for the transport of substrate is defined by the first alignment cylinder or a rotary transport body immediately upstream of the first alignment cylinder. Then coating agent with alignable particles can be applied to the substrate by means of the form-bound printing point and only provided with a particularly colorless additive by the at least one print head and thereby selectively cured in the curing device. It is therefore possible to write image information into the coating agent using the at least one print head and then fix it. This means that such image information can be entered into the coating agent with a very high resolution and in a particularly simple manner.

In an alternative or additional development, the printing unit is preferably characterized in that in the first curing area of the at least one first curing device, the transport path provided for the transport of substrate is fixed by the first alignment cylinder or a rotary transport body immediately downstream of the first alignment cylinder. Since the at least one print head was used to determine which areas should be hardened, the hardening can take place on the alignment cylinder or, if the alignment is sufficiently stable, after the alignment cylinder. This allows installation depending on the space available. In addition, a relatively simple curing device can be used.

In an alternative or additional development, the printing unit is preferably characterized in that a particularly colorless additive is arranged in a supply supply which is connected to the at least one first print head in terms of lines, which is in particular designed as an additive for changing the curing properties of applied material .
