The invention has for its object to provide a machine arrangement with a plurality of processing stations for processing sheets, the sheets being orientable relative to a printing position of a non-impact printing device.

The object is achieved by the features of claim 1.

The advantages achievable with the invention consist in particular in that the sheets to be processed in the machine arrangement can be aligned along their transport path relative to a printing position of a non-impact printing device. A hybrid sheet processing machine arrangement, preferably a hybrid printing machine, is formed, which has the high productivity of a conventional, e.g. B. in an offset printing process or in a flexographic printing process or in a screen printing process printing device variable in combination with at least one flexibly printing variable images, z. B. uses as an inkjet printer trained non-impact printing device, both the conventional printing device and the non-impact printing device in a running production are used inline with the optimum working speed for them. Such a hybrid machine arrangement is particularly suitable for the production of packaging materials, e.g. B. of sheets for the production of folding boxes is very advantageous because the strengths of each of the printing devices are used, which leads to flexible and economical production of the packaging. In particular, flexurally rigid printed sheets can advantageously be printed in a non-impact printing device in a flat state and in a horizontal position. The length of a linear transport device can be applied to a different number of printing units or printing stations (color separations) and (intermediate) dryer configurations, e.g. B. for water-based or UV-curing inks or inks than would be the case with a rotary transport device via cylinder. With a linear transport device when using sheets of variable format lengths, it is also easier to achieve a constant sheet gap between sheets that are transported at immediately spaced intervals. On the other hand, transporting printed sheets by means of rotary bodies, in particular cylinders and gripper bars or gripper carriages, each with a transfer of the sheets in the gripper closure to a next processing station, as is known from sheet-fed offset printing machines, ensures the highest possible register accuracy. With linear sheet transport z. B. by means of suction belt conveyors this register accuracy is currently i. d. R. not yet reached. Further advantages can be seen from the explanations below.

Exemplary embodiments of the invention are shown in the drawings and are described in more detail below.

Each of these processing stations is preferred 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12 each as a z. B. independently functional module, whereby a module is to be understood as a normally independently manufactured or at least one assembled machine unit or functional assembly. Each of the processing stations arranged in the respective machine arrangement 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12 is therefore preferably manufactured independently and is in a preferred embodiment, for.

A non-impact printing device 06 uses a printing process without a fixed printing form and can in principle print from print to printing material, e.g. B. each of these printing devices 06 Print the currently fed sheet with a print image different from the previous print image. The respective non-impact printing device 06 is realized in each case in particular by at least one inkjet printer or by at least one laser printer. Inkjet printers are matrix printers, in which a print image is created by the targeted firing or deflection of small ink droplets, the inkjet printer being used either as a device with a continuous ink jet (CIJ) or as a single device dropping ink drops (Drop On Demand = DOD) is formed. Laser printers generate the respective print image in an electrophotography process. The non-impact printing device 06 z. B. also referred to as a digital printing press.

B. is processed from a paper, from a single-layer or multi-layer cardboard or from a cardboard in particular to a packaging material. The substrates paper, cardboard and cardboard differ in their respective basis weight, ie the weight in grams for one square meter of this substrate. In general, the above-mentioned printing material with a basis weight between 7 g / m ² and 150 g / m ² applies as paper, between 150 g / m ² and 600 g / m ² as cardboard and with more than 600 g / m ² as cardboard. In particular, cartons are used for the production of folding boxes, which have good printability and for subsequent finishing or processing such as. B. are suitable for painting and punching. These cartons are z. B. wood-free, slightly wood-containing, wood-containing or waste paper. Multi-layer cartons have a structure Top layer, an insert and a backing on the back. From their surface quality, cartons are e.g. B. uncoated, pigmented, coated or cast coated. A format of the sheet is z. B. in the range between 340 mm x 480 mm and 740 mm x 1060 mm, with the format information usually the first number a length in the direction of transport T the sheet and the second number are orthogonal to the direction of transport T indicates the width of the sheet.

In the block diagram of the 1 each runs with several of the processing stations 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12 producible production line essentially from right to left, each of the two processing stations 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12 directional arrows connecting one another each have a transport path to be traversed by the printing material and an associated transport direction T suggests to go from a processing station 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12 to the next processing station selected in the machine arrangement intended for the respective production 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12 to get. Every production begins in the processing station 01 provided sheet, the processing station 01 as an investor 01 , e.g. B. as a sheet feeder 01 or as a magazine feeder 01 is trained. A sheet feeder 01 usually takes a z. B. on a pallet stacked stack of sheets, whereas a magazine feeder 01 has several compartments, in each of which sheets, in particular stacks of z. B. different types of sheets or sheets of different formats are inserted or at least insertable. The investor 01 isolated z. B. by means of a suction head 41 the stacked sheets and guides them in a sequence of sheets separated from one another or in a shingled stream of the next processing station in the specific production 02 ; 03 ; 04 ; 06 to. The next processing station 02 ; 03 ; 04 is z. B. as a primer applicator 02 or as a cold foil applicator 03 or as an offset printing device 04 or as a flexo printing device 04 educated. The next processing station 06 can also z. B. the at least one non-impact printing device 06 be. The offset printing device 04 is preferably designed as a sheet-fed offset printing press, in particular as a sheet-fed printing press with several printing units in series. The offset printing device 04 provides the sheets with at least one static print image, whereas the non-impact printing device 06 provides the sheets with at least one changing or at least variable print image.

If the the investor 01 next processing station 03 the cold foil application device 03 From there, the sheet is then usually used as an offset printing device 04 trained processing station 04 transported. In the cold foil applicator 03 a metallized lacquer layer detached from a carrier film is transferred to the printing material. By overprinting this layer of lacquer z. B. with an offset printing device 04 a wide variety of metal effects can be achieved. The cold foil application device 03 is advantageously z. B. in the offset printing device 04 Integrated design by providing two additional printing units in the offset printing device 04. In the first printing unit, a special adhesive is applied to the printing material, ie the respective sheet, using a standard printing form. A second printing unit is equipped with a film transfer device which has the lacquer layer to be transferred. The film carrying the lacquer layer is guided by an unwinding station into a printing nip between a transfer cylinder and a printing cylinder interacting with this transfer cylinder and brought into contact with the printing material. The paint layer is colored by an aluminum layer and a protective lacquer layer, the coloring of which influences the color impression. By adhesion of an adhesive layer with the printed adhesive layer, the transfer layers adhere to the substrate. The carrier film is then wound up again. After the cold foil transfer is inline, especially in the offset printing device 04 overprinting with conventional printing inks as well as UV and hybrid inks is possible in order to produce different metallic colors.

A z. B. particularly absorbent substrate is from the feeder 01 e.g. B. a primer applicator 02 as the next processing station 02 supplied in order to seal the surface of this printing material with a primer before printing or painting. Priming thus represents a primer or first coat of the printing material. In principle, one can be used in a primer application device 02 processed sheet as the next processing station 02 also an offset printing device 04 and then z. B. a non-impact printing device 06 are fed.

The z. B. as a flexographic printing device 04 trained processing station 04 executed flexographic printing is a direct high-pressure process, in which the raised areas of the printing form are image-bearing, which is often used for printing on packaging materials made of paper, cardboard or cardboard, from metallized film or from a plastic such as, for. B. PE, PET, PVC, PS, PP, PC is used. Low-viscosity printing inks and flexible printing plates made of photopolymer or rubber are used in flexographic printing. Generally includes a flexo printing device 04 a) an anilox roller, via which the printing form is inked, b) a printing cylinder, also format cylinder called, on which the printing form is attached, and c) an impression cylinder which guides the printing material.

The one as a flexo printing device 04 or as an offset printing device 04 trained processing station, each printing the sheets with at least one static print image 04 preferably has several, z. B. at least four printing units, each printing unit preferably printing a different printing ink, so that the printing material when passing through the flexographic printing device 04 or the offset printing device 04 each multi-colored, e.g. B. is printed in a four-color print. In an alternative embodiment, the processing station is printing the sheets with at least one static print image 04 as a printing device printing in a screen printing process 04 educated.

After processing the printing material in the at least one non-impact printing device 06 is this substrate z. B. one as an intermediate dryer 07 trained processing station 07 fed, this intermediate dryer 07 as a printing substrate in question z. B. is formed by radiation with infrared or ultraviolet radiation drying, the type of radiation is particularly dependent on whether the printing ink or ink applied to the substrate is water-based or UV-curing. After the intermediate drying, the printing material is z. B. one as a painting device 08 trained processing station 08 fed. The painting facility 08 bears on the substrate z. B. a dispersion varnish, wherein dispersion varnishes consist essentially of water and binders (resins), with surfactants stabilizing these dispersions. A coating device that applies a dispersion varnish to the printing material 08 consists either of an anilox roller, a chambered doctor blade and an application roller (comparable to a Flexo printing unit) or an immersion and application roller. By means of a printing form, preferably based on photopolymerization, for. B. applied flat and / or partial paint. Special rubber coating plates can also be used for full-surface painting. In the transport path of the printing material is after the coating device 08 e.g. B. one as a dryer 09 trained processing station 09 arranged, this dryer 09 is designed as a drying of the relevant printing material by irradiation with infrared or by hot air. If the dryer 09 a printing material drying by means of ultraviolet radiation is supplied, ie a printing material on which a printing ink or ink curing by UV radiation or a varnish curing by UV radiation, e.g. B. a gloss varnish is applied, this is a dryer 09 equipped with an ultraviolet radiation generating source. With dispersion varnishes, more intensive gloss and matt effects can be achieved compared to classic oil printing varnish. Special optical effects can be achieved with effect pigments in the paint. The primer application device 02 , the cold foil applicator 03 and the painting facility 08 can under the term coating device 02 ; 03 ; 08 be summarized.

After drying, the substrate is z. B. a processing station 11 fed, which carries out mechanical processing on the substrate, e.g. B. by punching, creasing and / or separating parts, in particular breaking out benefits from their respective composite in the preferably printed sheet. Each of the aforementioned further processing operations is carried out in or by a processing plant. The mechanical further processing is preferably carried out in cooperation with a cylinder transporting the respective sheet. Afterwards or directly from the dryer 09 the substrate comes to a delivery 12 which in each of the in the 1 shown, each by a certain arrangement of processing stations 01 ; 02 ; 03 ; 04 ; 06 ; 07 ; 08 ; 09 ; 11 ; 12 production lines each represented the last processing station 12 forms.
