printing unit

The invention relates to a printing unit according to the preamble of claims 1, 2, 3, 7, 9, 11, 13 or 28.

A four-cylinder printing unit is known from DE 19603663 A1, the two interacting transfer cylinders being firmly coupled to one another and being able to be driven either via the drive of one or both associated forme cylinders or via a transverse shaft which can be connected to the motors. In one operating mode, one of the forme cylinders can be stopped for the purpose of changing the plate, while the assigned transfer cylinder continues to run synchronously with the second forme cylinder.

EP 0997273 A2 discloses an operating mode of a four-cylinder printing unit, with one forme cylinder being set apart from the other cylinders which act together. The parked forme cylinder is rotatable in one example by a drive motor and in another example by an auxiliary motor.

The invention has for its object to provide a printing unit.

The object is achieved by the features of claims 1, 2, 3, 7, 9, 11, 13 or 28.

The advantages that can be achieved with the invention consist in particular in the fact that a great variety of operations and variability of a printing unit or a cylinder assembly are created.

For example, cylinders or cylinder groups can be move at different speeds or directions of rotation, which is necessary, for example, when changing the printing form or blanket, when pulling in a paper web, when inking or washing rollers and cylinders independently. In particular, different actions of the setup with standstill (zero speed) or the production speed different setup speed or speed for the individual cylinder types are thus possible side by side, or with the paper web running or standing.

The simultaneous fulfillment of several different requirements for different components of a printing unit or a printing unit is particularly advantageous. On the one hand, the operating modes help to save time and thus reduce the unit product costs and, on the other hand, it enables various setup work to be carried out with the paper web running at production speed or at feed speed. A flying plate change for one- or two-sided imprint operation is possible. For example, in advantageous operating states, a printing form is changed or pre-inked, while the assigned transfer cylinder continues to rotate at production speed, or washing, pre-inking or likewise a change of the elevator takes place.

An advantageous operating mode in the case of two pairs, each having a forme cylinder and a transfer cylinder, is the rotation of one of the two forme cylinders at a set-up speed, while the other cylinders continue to rotate at production speed. Both transfer cylinders can also stand still or rotate at a speed for drawing in a paper web or at production speed while one of the form cylinders or both are being colored.

Also for four-cylinder printing units and in particular for eight-cylinder printing units formed from two four-cylinder printing units are diverse, particularly with regard to the flying plate change or the imprinter functionality Operating conditions advantageous. A printing operation can be maintained, for example, while one or more forme cylinders, at different speeds from the production speed and z. T. also direction of rotation, is or will be changed.

A y- or λ-shaped six-cylinder printing unit is e.g. B. can be used flexibly for 2/1 continuous printing or also for the flying plate change or in imprint function during 1/1 printing, if one of the forme cylinders is operated with a speed and direction of rotation for the change, while all other cylinders with Turn production speed. The transfer cylinder assigned to the forme cylinder to be changed is operated, for example, simultaneously with a speed and direction of rotation for washing or other preparation. The same applies to the above. Seven, nine or ten cylinder printing unit.

When setting up before starting up or when printing is finished, the operating states are of great importance due to flexibility and time and waste savings. For example, the forme cylinder and transfer cylinder can run through different setup programs at the same time.

Independent operation of the rollers assigned to the forme cylinders for ink application is also advantageous. For example, washing or pre-inking takes place regardless of the speed and direction of rotation, while the forme cylinder also runs through a set-up program.

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

A printing unit of a printing press, in particular a rotary printing press, has a first cylinder 01, e.g. B. a forme cylinder 01, and in a pressure-on position cooperating second cylinder 02, z. B. a first transfer cylinder 02 of a printing unit 03. The forme cylinder 01 can with a roller 04, z. B. an inking roller 04, in particular an inking roller 04 or an anilox 04 or anilox roller 04, act together. The transfer cylinder 02 cooperates in a print-on position with a web 06, for example a printing material web 06, in particular a paper web 06.

The forme cylinder 01 can be rotated independently of the transfer cylinder 02, ie it rotates depending on the operating state, for. T. with different speeds and / or directions of rotation from the transfer cylinder 02. Likewise, the transfer cylinder 02 rotates z. T. regardless of the forme cylinder 01. The operating states are defined below by means of speeds or effective peripheral speeds on the lateral surfaces, hereinafter referred to as “speeds”. The operating states mentioned with the term “speed” are to be applied to the term “speed” in the same way.

The forme cylinder 01 can assume one or more of the following operating states: it can be at a standstill, i. H. Turn commercial vehicle at a "zero" speed, but it can also rotate at a production speed PFZ or a set-up speed RFZ, which is usually different from the commercial vehicle standstill and the production speed PFZ.

The set-up speed RFZ can in turn be a speed DWFZ for changing the printing form, a speed VEFZ for pre-inking or a speed WFZ for washing. A further set-up speed RFZ can also be a speed TFFZ for dry running, i. H. the decolorization of the forme cylinder 01 on the web 06, or a speed EFZ for the drawing in of the web 06. In the case of direct imaging of the surface of the forme cylinder 01 or the printing form on the forme cylinder 01, the set-up speed RFZ can also represent a speed BBFZ for the imaging.

The transfer cylinder 02 can also assume one or more of the following operating states: it can be at a standstill, i. H. it rotates at a speed of "zero" NÜZ, it can rotate at a production speed PÜZ or a set-up speed RÜZ, which is usually also different from the standstill commercial vehicle and the production speed PFZ. The set-up speed RÜZ can in turn be a speed AWÜZ for changing the elevator , a speed EÜZ for drawing in a web 06, a speed WÜZ for washing or a speed VEÜZ for pre-inking the transfer cylinder 02.

The production speed PFZ for the forme cylinder 01 is z. B. between 20,000 and 50,000 revolutions per hour (U / h), preferably at 35,000 to 45,000 U / h. The production speed PÜZ of the transfer cylinder 02 also between 20,000 and 50,000 U / h, preferably at 35,000 to 45,000 U / h.

The speed VEFZ of the forme cylinder 01 which is characteristic of the pre-inking is, for example, in the range from 6,000 to 12,000 rev / h.

The speed VEÜZ of the transfer cylinder 02 is for example between 6,000 U / h to 12,000 U / h.

For washing the forme cylinder 01, the speed WFZ is z. B. at 200 to 1,000 U / h, in particular between 300 and 800 U / h, while the speed WÜZ for washing the transfer cylinder 02 z. B. can be between 300 and 40,000, in particular between 300 to 6,000 U / h.

The speed EFZ of the z. B. moving forme cylinder 01 for pulling the web 06 is, for example, 300 to 2,000 U / h, in particular 300 to 800 U / h, which is approximately a pulling speed for the web 06 of 6 to 30 m / min, in particular 6 to 12 m / min.

The rotational speed EÜZ of the transfer cylinder 02 for pulling in the web 06 is, for example, 300 to 2,000 U / h, in particular 300 to 800 U / h, which is approximately a pulling speed for the web 06 of 6 to 30 m / min, in particular 6 to 12 corresponds to m / min.

The speed DWFZ for the automatic change of the printing form can be between 300 U / h and 2,000 U / h, in particular between 300 and 1,000 U / h, with the direction of rotation usually being reversed during the change process. The speed DWFZ can, however. B. in so-called. Jog mode, between 120 and 300 U / h. With direct imaging of the printing form or the cylinder surface on the forme cylinder 01, z. B. using laser / (diodes), the speed BBFZ of the forme cylinder 01 is usually above the production speed PFZ, for example over 50,000 U / h, in particular over 70,000 U / h for web-fed rotary printing presses, and over 5,000 U / h, in particular between 5,000 and 30,000 U / h for sheetfed presses.

For changing the elevator on the transfer cylinder 02, the speed AWÜZ is between 300 and 2,000 U / h, in particular between 300 and 1,000 U / h. If the elevator change is carried out manually, as is currently preferred, the speed AWÜZ can also be between 120 and 1,000 rev / h.

The speed TFFZ of the forme cylinder 01 for dry running, d. H. Decolorization of the forme cylinder 01 lies z. B. between 2,000 and 4,000 U / h.

The speeds mentioned for forme cylinder 01 and transfer cylinder 02 preferably relate to cylinder 01; 02 double the circumference, d. H. on cylinder 01; 02, on the circumference of which two printing forms can be fastened one behind the other in the circumferential direction. The scope of this depends on the format and is e.g. B. between 900 mm and 1,300 mm. For the use of cylinders 01; 02 simple circumference, the speeds for the form 01 and the transfer cylinder 02 are to be doubled. The same applies to printing units 03, wherein a forme cylinder 01 with a single circumference interacts with a transfer cylinder 02 with a double circumference.

For one or more of the mentioned speed ranges of the forme cylinder 01 and the transfer cylinder 02, the directions of rotation are counterclockwise and clockwise. These directions of rotation are defined in the following figures, which show the side views of the cylinders 01; 02 represent.

The operating states mentioned and preferred speeds are also below to apply further shape cylinders, transfer cylinders, added in the description.

The inking roller 04, designed as an anilox or anilox roller 04 or as a rubberized inking roller 04, can also be at a standstill. H. it rotates at a speed "zero" NW, with a production speed PW or with a set-up speed RW. The set-up speed RW can be a speed VEW for pre-inking, a speed WW for washing or a speed W W for continuing the ink roller 04.

The preferred speed ranges for the inking roller 04 depend on the printing process and / or on the configuration of the printing unit or the inking unit.

In the following, a distinction should be made between a simple rubberized inking roller 04, an anilox 04 or anilox roller 04 and an anilox roller 04 of double circumference. The ink roller 04, designed as a simple, rubberized inking roller 04, preferably has approximately one third of the circumference of a forme cylinder 01 of double circumference. An anilox roller 04 which interacts directly with the forme cylinder 01 can have the circumference of a forme cylinder 01 of a single circumference, or, in particular in high or flexographic printing, of a forme cylinder 01 of twice the circumference.

The production speed PW is z. B. between 40,000 to 100,000 U / h for the anilox 04 directly interacting with the forme cylinder 04 or anilox roller 04 single circumference, and between 60,000 and 150,000 U / h for the case of the inking roller 04. For the anilox roller 04 the circumference is Production speed PW z. B. between 20,000 to 50,000 U / h.

The speed VEW for pre-inking the ink roller 04 is z. B. between 12,000 to 24,000 U / h in the case of anilox 04 or anilox roller 04 simple scope and between 18,000 and 36,000 rpm for the case of an inking roller 04.

The speed WW for washing the ink roller 04 is z. B. 600 to 1,600 U / h in the case of an anilox 04 or anilox roller 04 of simple scope and is between 900 and 2,400 U / h for the case of an inking roller 04.

To keep the ink roller 04 running against drying of the ink, the speed WLW is preferably between 3,000 and 6,000 rpm for the anilox roller 04 of double circumference, between 6,000 and 12,000 rpm for the anilox roller 04 of single circumference and between 9,000 and 18,000 rpm. h for the inking roller 04.

As already mentioned above, the operating states mentioned are also defined at effective peripheral speeds, in short speeds, of the rotating body:

The production speed of the forme cylinder 01 PFZ is z. B. between 6.4 and 16 m / s, in particular between 11 and 15 m / s. The same applies to the transfer cylinder 02, if available.

The speed of the forme cylinder 01 PWFZ for the automated change of the printing form lies e.g. B. between 0.32 and 0.64 m / s, for manual change z. B. between 0J0 and 0.32 m / s. The speed VEFZ of the forme cylinder 01 is z. B. between 1.9 and 3.9 m / s, while for washing the printing form WFZ z. B. is between 0.06 and 0.32 m / s, in particular between 0J0 and 0.26 m / s. For dry running TFFZ of the printing form, the speed of the forme cylinder 01 is z. B. between 0.64 and 1.3 m / s. The speed of the forme cylinder 01 for BBFZ imaging is generally greater than 16 m / s, in particular greater than 22 m / s for web printing machines, and for sheet-fed machines greater than 1.6 m / s, in particular between 1, 6 and 9, 6 m / s. For pulling in the web is the speed EFZ of the forme cylinder 01 z. B. between 0.10 and 0.50 m / s, in particular between 0J0 and 0.2 m / s.

The same values or ranges of the forme cylinder 01 are advantageous for the transfer cylinder 02 for the corresponding operating states of pre-inking VEÜZ, for changing the elevator AWÜZ and for pulling in the web EÜZ. The speed of the transfer cylinder 02 AWÜZ for the manual change of the elevator is between 0.04 and 0.32 m / s. When washing the transfer cylinder 02 WÜZ its speed is z. B. between 0J0 and 13 m / s, in particular between 0.10 and 1.9 m / s.

The speeds for the inking roller 04 depend on the speed of the operating state in the state in which the forme cylinder 01 is positioned, so that, for example, the production speed of the inking roller 04 PW is likewise in the range between 6.4 and 16 m / s, in particular between 11 and 15 m / s lies. If the inking roller 04 is designed as anilox roller 04, its scope can then, for. B. correspond approximately to the circumference of a forme cylinder 01 simple circumference. Is the size of the anilox roller 04 selected larger, z. B. between 1.0 and 1.2 m, the above are. Speed PW to choose smaller. The same applies in the case of inking rollers 04 designed as inking roller 04, the speed to be selected again depending on the size of the inking rollers 04, which, for. B. is between 0.35 and 0.5 m.

The speed of the ink roller 04 is for pre-inking z. B. between 1.9 to 4.0 m / s. and for washing between 0.08 and 0.3 m / s. To continue running, the speed of the inking roller 04 is z. B. between 0.95 and 1.95 m / s.

When in the lower circumferential area or below the diameter of the anilox roller 04, as z. B. with a double large forme cylinder 01 is advantageous in the direct printing process, the above ranges of speeds for the anilox roller 04 in one advantageous embodiment to the corresponding speed, z. B. to increase by 0 to 30%, in particular by 10 to 20%, so that the advantageous range for the speed is approximately maintained.

Suitable or desired speeds for the named, as cylinder 01; 02 and rollers 04 rotating body 01; 02; 04 can be determined based on the advantageous speeds with knowledge of the effective ranges for the most varied diameters.

In the figures, the rollers 04 are generalized for simplicity and shown with a uniform diameter. In the exemplary embodiments, the operating states are described on the basis of rotational speeds. However, the same exemplary embodiments can also be read on the speeds characterizing the operating states.

In order to limit the number of figures, the arrangements of the cylinders 01; 02 and rollers 04 are shown spaced from each other.
