Multicolor sheet-fed printing press

FIELD OF THE INVENTION

The invention relates to a sheet-fed rotary printing machine for multicolor printing.

BACKGROUND OF THE INVENTION

For the printing of small-format printing sheets it is a known practice to use printing units in which the cylinders participating in the printing, such as a plate cylinder, a rubber cylinder and a printing cylinder, have different diameters. Thereby mechanical expenditure can be saved in the field of the printing plates, of the rubber blankets or of the printing cylinder.

From DE-PS 24 35 203 there is known a sheet-fed rotary printing machine. It has, in the most diverse configurations, a plate cylinder with single or simple diameter, a rubber cylinder with multiple diameter and a printing cylinder with single diameter. Thereby from differently usable printing units from a particular plate cylinder a partial image of a print image can be printed on one of several segments of the rubber cylinder. Simultaneously this print image can be printed on a printing sheet guided on the printing cylinder, in which process the printing sheet with the printing cylinder revolves in correspondence to the movement of the segments of the rubber cylinder and is printed from this latter.

In U.S. Pat. No. 3,347,160 there is described an ink roller device for a multicolor rotary offset printing machine. This printing machine has a plate cylinder and a rubber cylinder in each case with multiple diameter to which there is allocated a printing cylinder with simple diameter. In the printing process the printing plate consisting of several image parts is generated on the plate cylinder from several cycled inking and moistening units, transferred to the multiply large rubber cylinder, and printed on a printing sheet guided on the printing cylinder. There the printing cylinder rotates a number of times corresponding to the diameter ratio between rubber cylinder and printing cylinder, until all the print image parts have been transferred onto the printing sheet. This multicolor printing machine is suited for the so-called proof printing.

What is disadvantageous in these devices is that even though they can be produced, to be sure, as individual printing units, the expenditure for the printing with images that contain more ink than the particular printing machine permits is very high. These printing machines, therefore, are suited only for special printing processes.

OBJECTS AND SUMMARY OF THE INVENTION

An object of the invention is to present a machine configuration which, with the simplest construction, has arbitrarily combinable printing mechanisms for the generating of prints with a different number of colors, renders unnecessary any changing of assemblies and is suited for high throughput with arbitrary edition levels.

Another object of the invention is to improve a device of the foregoing type, so that from standard elements there results a simple and therewith cheap printing machine which, by combining components of this type with one another, allow differently configurable multicolor printings, without it being necessary for the printing machine to be re-outfitted or to have too low a performance.

The present invention provides these and other advantages and overcomes the drawbacks of the prior art by providing a sheet-fed printing machine for printing sheets in a plurality of colors in which all the plate cylinders are provided with two printing plates and that in all the sheet conducting cylinders or drums there is only one gripper arrangement in operation. Here it is especially advantageous that, on the basis of standard printing machines, simplified forms of execution of printing machines are produced which with little expenditure permit economical printing processes, in which heed is given to a so-called “slim” or slender sheet running and the costs for building the machine are reduced because simple elements are used.

In the first place this can occur through the use of a printing cylinder with single diameter which rotates a number of times for the reception of the print images, while the other cylinders or drums provided with the same or with doubled diameter rotate only at half the speed of the printing cylinder.

In a further form of execution the rubber cylinder is constructed as a cylinder provided with single diameter. In standard printing processes proposed for this, it collects the prescribed print images of different colors on the plate cylinder and prints them in a single printing operation onto the printing sheets held on the printing cylinder.

These and other features and advantages of the invention will be more readily apparent upon reading the following description of preferred exemplary embodiments of the invention and upon reference to the drawings wherein:

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

In

FIG. 1

there is represented a sheet-printing machine which comprises a feeder unit

1

, a discharge or delivery unit

2

and a printing mechanism

3

. The printing sheets are fed from the feeder unit

1

to the printing mechanism

3

and laid out in the discharge unit

2

. For the sheet transport there is provided a feed drum

4

which transfers the printing sheet to a printing cylinder

5

, from where the printing sheet is transported on further sheet-guide drums

6

and

7

to a discharge or delivery drum

8

and then deposited in the discharge unit

2

. The feed drum

4

, the sheet guide drums

6

and

7

and the discharge drum

8

have a so-called doubled diameter. The printing cylinder

5

has a single or simple diameter.

The diameter ratio relates to the length of a maximally-to-be-processed printing sheet. In the printing mechanism

3

there is arranged, further, a rubber cylinder

9

and a plate cylinder

10

, which both have a doubled diameter.

The sheet-conducting cylinders or drums, insofar as they are provided with doubled diameter, can be equipped with one or two gripper rows for the transport of printing sheets.

In principle, however, it should hold for these and all the printing machines described in the following that a plate cylinder

10

is provided which is spannable with two printing plates. The sheet-conducting drums and cylinders should in principle, regardless of their diameter and the number of their working surfaces, be suited for the transport of a single printing sheet. This can be solved by the constructive restriction to only one gripper row or working surface or by control-technical equipment in the arrangement with several gripper rows or working surfaces.

Before the printing of a printing sheet, this sheet is fed by a pre-gripper

15

to the feed drum

4

and from there it is given over to the printing cylinder

5

. The print images that are generated on a plate cylinder

10

with doubled diameter and two working surfaces, are transferred to a rubber cylinder

9

likewise with doubled diameter and two working surfaces, and printed during two revolutions of the printing cylinder

5

as two-color print on the printing sheet held there.

The sheet is guided there in a relatively stretched position and is pressed by depressing in a single gripper closure in a position in an exact register between the print images of the various printing inks. When there is a mention of print images, as a rule in the case of several print images, there are meant the different-colored partial images of a multicolor print. Only in the case of monochrome printing is this not the case.

On the other hand, with this printing machine a production process is also imaginable, in which only prints of a single color are generated. There it is possible to provide the image to be printed on the plate cylinder

10

once or twice. Therewith there can occur per revolution of the plate cylinder

10

in each case two prints or, per revolution of the printing cylinder

5

in each case one print. On the other hand, even if only a single image is provided, the control on the layer-on drum

4

can be provided in such manner that only with every other gripper row a sheet is taken off, and therewith a very simple monochrome printing machine results. Constructively this is also obtained when all the sheet-conducting cylinders or drums have only one working surface or only one gripper row. The alternative also shows that a printing machine operating with a half turn or one turn is generated, which generates one printed sheet either per printing cylinder revolution, or for every other revolution of the printing cylinder.

In

FIG. 2

there is represented a printing machine of the configuration from

FIG. 1

, with two printing units. Between the feeder unit

1

and discharge unit

2

there are arranged the printing mechanisms

11

and

12

. In configuration, they correspond to the printing mechanism seen in FIG.

1

. They have in each case a plate cylinder

10

, a rubber cylinder

9

and a printing cylinder

5

, the printing cylinder

5

having half the diameter of the adjacent cylinders. From the printing cylinder the sheet is transferred in each case to a sheet guide drum

6

. The graphic representation there also shows the correspondence between the fee drum

4

and a sheet guide drum

13

. Further, the two printing mechanisms

11

and

12

are connected by a third sheet guide drum

14

. Feed drum

4

and sheet guide drum

13

have only the distinction that the feed drum

4

cooperates with a pre-gripper arrangement

15

.

With a printing machine of this form of construction, a multicolor printing machine can be combined simply from the basic components plate cylinder

10

, rubber cylinder

9

, printing cylinder

5

, sheet guide drum

6

and sheet guide drum

13

or

4

. The connection between the printing units

11

,

12

is established by means of the sheet guide drum

14

, which corresponds to the sheet guide drum

7

, which also leads to the discharge unit

2

. The printing machine is constructed from identical printing units and is very compact in the zone of the printing cylinder

5

. Further, through the arrangement of two working surfaces on plate cylinder

10

and on rubber cylinder

9

with doubled diameter their handling is improved.

Thus it is possible to provide, on the plate cylinder

10

, printing plates with one or two print images, so that different types of production are possible as under FIG.

1

.

The printing machine in

FIG. 2

makes it possible to bring in two colors with doubled throughput if in both printing units

11

and

12

, in each case two print images are provided on the plate cylinders, which are arranged in like color. Further, it is possible to work in two colors with half throughput, if in each printing unit

11

and

12

on the respective plate cylinder

10

only one print image each is provided, which then have a different color.

There are yielded there further production possibilities from three-color to four-color printing. These production types run in the half-sheet-throughput mode.

Finally for small editions a double edition can also be run, as on each printing plate of the plate cylinder

10

another monochrome image is generated and on each printing sheet, in each case alternatively, the one and the other print image are printed. The different print sheets then can be deposited onto different stacks, for example, with the aid of an auxiliary discharge unit

16

and that of discharge unit

2

. For this a control is required on the drum or cylinder allocated to the auxiliary discharge unit

16

, which provides that every other printing sheet is sluiced out.

Furthermore, the sheet guide drums

6

,

13

,

14

can also be provided as a so-called turning device. They then have devices by means of which a printing sheet is taken off from the middle sheet guide drum

14

on its rear edge and is fed in inverted position and reversed transport direction to the next printing unit. Then the printing sheet is printed there on its reverse side. In this manner the printing machine is then capable of printing on two sides in one color, on one side in two colors and on the other in one color and on two sides in two colors. These principles are known.

The printing machine is, furthermore, extensible to many further printing units.

The printing machine according to

FIGS. 1 and 2

have, further, as a special feature an additional auxiliary discharger

16

. In this case, as needed, a proof sheet can be laid out or this position can be used as waste depository. The auxiliary discharge unit

16

is operated by delivery of a printing sheet from the discharge drum

8

by means of a flexible control arrangement in engagement with the grippers of the discharge drum

8

.

A further machine configuration is shown in FIG.

3

. Between the feeder unit

1

and the discharge unit

2

there is arranged a printing unit

17

, which as already known, has a feeder drum

4

, a plate cylinder

10

, a sheet guide drum

6

, a sheet guide drum

7

and a discharge drum

8

. Here, too, there is provided the auxiliary discharger

16

, and the feeder drum

4

operates together with a pre-gripper system

15

. Here there is provided a print cylinder

22

which has a doubled diameter, i.e. it has a circumference that corresponds to two format lengths. There it can have one or two working surfaces. It cooperates with a rubber cylinder

21

which has only a single diameter.

This printing machine operates, unless it is provided for monochrome printing, according to the so-called rubber collecting print process. This means that in the rotation of the rubber cylinder

21

two partial images provided on the plate cylinder

10

of a print image are superimposed on one another and are printed in common in a printing zone, on printing sheets that are held on the printing cylinder

22

.

This configuration can also be expanded in such manner that to the printing cylinder

22

there can be allocated two printing units with a rubber cylinder

21

and a plate cylinder

10

in such manner that on every other revolution of the printing cylinder

22

a four-color print is generated. There, as is generally known, the printing zones of the rubber cylinders

21

with the printing cylinder

22

are laid so far apart that the first printing is completed before the second printing begins.

In a printing machine of this construction type various printing processes are conceivable. For one, on each rotation of the rubber cylinder

21

a monochrome image can be printed on printing sheets that are held on the printing cylinder

22

. There, on the printing cylinder

22

there must be provided a series of two working surfaces and two gripper rows, which are loaded with individually with a printing sheet on each revolution. On the plate cylinder

10

, then, there must be provided two like print images for a single printing color.

The production manner for a single print image on the plate cylinder

10

is possible with simply occupied sheet-guiding drums or cylinders with full throughput, i.e. with one printing sheet per revolution. It can also be provided, however, that on a doubly occupied printing cylinder

22

with two working surfaces only every other gripper row is loaded with a printing sheet and thus also only on every other revolution of the rubber cylinder

21

there is generated a print image in the print zone between rubber cylinder

21

and printing cylinder

22

.

Finally, as described earlier, on the plate cylinder

10

it can be arranged to provide two differently colored partial images of a single print image. There on the rotation of the rubber cylinder

21

first the one print image is transferred to the rubber blanket and then the second print image is superimposed onto this. The print images now superimposed on one another are then printed in common in the print zone between the rubber cylinder

21

and the print cylinder

22

on the printing sheet supported there. Thus, on each revolution of the rubber cylinder

21

, a two-color print can be generated, in which process the printing machine is driven with half throughput, i.e. with loading of every other gripper row on feed drum

4

or printing cylinder

22

with a printing sheet. This obviously holds only if the printing machine, on the sheet-conducting cylinders, is not occupied with only one working surface and (one) gripper row.

In

FIG. 4

there is provided a corresponding printing machine according to

FIG. 3

with several printing units. Between the feeder unit

1

and discharge unit

2

there are provided two printing units

18

and

19

. These are configured alike in correspondence to FIG.

2

. There, both have a plate cylinder

10

, a rubber cylinder

21

, a printing cylinder

22

and a sheet guide drum

6

.

In a corresponding manner the feed drum

4

and a sheet guide drum

13

are allocated to the printing cylinder

22

, in which case only the feed drum

4

operates with a pre-gripper system

15

. Finally, both printing units are connected with a sheet guide drum

14

, which, however, corresponds to the sheet guide drum

7

and which again leads to the discharge drum

8

. The configuration of the printing machine permits the printing of up to four-color prints with different throughputs in printing sheets.

Fundamentally also this machine again operates according to the rubber-collecting printing process like that from FIG.

3

. Therewith in printing units

18

and

19

there can in each case be generated a two-color print, in which the two prints can supplement each other so that altogether a four-color print results. This four-color print, after a proof phase, is generated in each case with altogether two revolutions of the rubber cylinders

21

of both printing units.

Further, however, on the plate cylinder

10

there can be provided only one monochrome image; then this printing machine would print in two colors and only on every other revolution of the rubber cylinder

21

would it generate a print sheet, that is to say one printing sheet printed in two colors for each revolution of a printing cylinder

22

.

Finally it can also be provided to print on each plate cylinder

10

with two print images, so that in each revolution of the rubber cylinder

21

a print image can also be transferred to the printing cylinder

22

. Then again, with the full throughput on the printing cylinder, the work is done with two printing sheets per revolution, which then, however, are printed with one color in the first printing unit and with a second color in the second (unit).

This printing machine, too, is provided with an auxiliary discharge unit

16

.

In this machine also it is possible to install a turning arrangement and thereby to create the possibility for two-sided printing in different configurations as described further above. Finally, in

FIGS. 5 and 6

there is represented a further configuration of the printing machine according to FIG.

3

. It, too, has between the feeder unit

1

and discharge unit

2

a printing mechanism

20

, in which there are provided a plate cylinder

10

, a printing cylinder

22

, a feed drum

4

and a sheet guide drum

6

. Between plate cylinder

10

and printing cylinder

22

there is provided a rubber cylinder

21

which has a single diameter. The basic configuration corresponds to that in FIG.

3

. Therewith, therefore, monochrome or two-color prints can be generated in different throughputs. Further, to the sheet guide drum

6

there is allocated a further printing unit. This printing unit consists of an inking mechanism

24

which is slidably arranged, a plate cylinder

25

and a rubber cylinder

26

. The plate cylinder

25

and the rubber cylinder

26

are provided only with single diameter and are thus recognizably suited only for the applying of a single print image color. What is essential is the arrangement of the rubber cylinder

26

on the underside of the sheet guide drum

6

, which here takes over the function of a printing cylinder. Since the printing sheet, after it was printed on the upper side between rubber cylinder

21

and printing cylinder

22

, now is in contact with the sheet guide drum

6

with its printed side, its reverse side lies opposite the rubber cylinder

26

and can be printed from there. Therewith it is possible to generate, in this printing machine, a two-color printing on the one side to be completed with a further print image on the other side of the printing sheet. Furthermore, a monochrome print can also be generated on both sides.

In

FIG. 6

there is represented a configuration similar to that in FIG.

5

. Here, to be sure, as a perfecting printing mechanism a plate cylinder

25

A with doubled diameter is to be combined with a rubber cylinder

26

with single diameter, so that here also the perfecting printing proceeds according to the rubber collecting principle. The printing machine is therefore capable of operating 2/1-color with half throughput, as well as 2/2-color with half throughput. To the plate cylinder

25

A there is allocated for this purpose an inking mechanism

24

A drivable in a known manner. This inking mechanism

24

A contains two inking arrangements and possibly also two moistening arrangements, which are cyclically switchable top that they are capable of applying either one, or two, colors to the plate cylinder

25

A. In the machines according to

FIGS. 5 and 6

no sheet turning is required.

It is important for the execution of the production manners described that the inking mechanisms or the inking-and-moistening moistening mechanisms are to be formed flexible; this, however is known from the state of the art. According to this each inking mechanism must, for each cylinder revolution, be switchable on and off or settable on and off. To this end, in the case of a plate cylinder with doubled diameter and two images lying in succession, there may be provided an arrangement of two inking mechanisms

40

,

42

(shown in

FIG. 7

) lying in succession, which are activated individually and thus can ink the print images differently. Further, it should be possible to ink the two print images thoroughly with a single color, and to moisten them. For this only one inking or inking-and-moistening mechanism is set in continuous operation.

Further, possibly in the application of two printing inks, the operation should be performed only with one moistening mechanism. For this, one moistening mechanism is shut off and the other one is set in continuous operation. Moreover, the printing machine can also be provided only with a single moistening mechanism per printing unit.

With these arrangements and construction means known in themselves for the control of inking and moistening mechanisms the operation with all the printing machines described is possible in the different manners of production specified.

In

FIG. 7

a printing mechanism according to the inventive principle is represented in a larger scale. With the aid of this figure the mode of functioning of the earlier-described printing machines can be theoretically explained. The plate cylinder

10

is provided with doubled diameter, and is occupied with two printing plates P

1

and P

2

. The rubber cylinder

9

also is provided with doubled diameter and with two rubber blanket sections G

1

and G

2

. The sheet-conducting drums

4

and

6

also are provided with doubled diameter. The division of the corresponding cylinder indicated in

FIG. 7

is to be related only to the occupation of the parts with working surfaces such as printing plates, rubber blankets or sheet guide surfaces, not, however, to their rotary position to one another. Obviously the cylinders are coupled with one another in such manner that the print images are printed in exact register to one another and on the printing sheet.

The printing cylinder

5

is provided exclusively with a single diameter. It can, however, also provided with doubled or with triple diameter.

To the feed drum

4

a print sheet is fed from a pre-gripper

15

and then conducted onward to the printing cylinder

5

. In the printing the sheet feed is attuned so that there is taken into account the pre-run required on the plate cylinder

10

and the rubber cylinder

9

for the inking of the printing plates P

1

, P

2

and of the corresponding sides of the rubber blankets G

1

, G

2

. There the printing machine first executes an empty revolution during which the first printing plate P

1

is inked. When this reaches the first rubber blanket section G

1

the second printing plate P

2

is inked and the printing cylinder

5

revolves idly, since on the second rubber blanket section G

2

there is not yet any print image present. Now the sheet feed must begin, since in the half revolution the first print image on the rubber cylinder

9

reaches the printing cylinder

5

. This is a half-turn of the feed drum

4

away from the sheet onlay. Thus the first printing sheet reaches the printing cylinder

5

when the rubber cylinder

9

readies the first print image or the first color of the print image. In the next half revolution of the printing machine again no printing sheet is fed in, since then the printing sheet makes a second revolution on the printing cylinder, there to take off the second print image from the rubber cylinder

9

. After this a printing sheet again is fed in, and so forth. The feed drum

4

is executed accordingly as a half-occupied cylinder; i.e. only one half of the feed drum

4

is provided with a sheet-guiding surface and a corresponding gripper system. In the case of a doubly occupied feed drum

4

with two gripper rows, for the normal manner of operation the second row of grippers is to be inactivated.

The same principle holds also for printing machines with single-sized rubber cylinder corresponding to

FIGS. 3

,

4

,

5

and

6

. There also the completed two-color print images must be always first be transferred to the rubber cylinder

9

before they can be printed in one passage on the printing sheet held on the print cylinder

5

. To assure that no printing ink passes onto a sheet-conducting surface of the printing cylinder

5

, it is advantageous to execute the printing cylinder

5

half-occupied, so that in the taking up of the second print image no printing surface stands opposite the rubber cylinder

9

. Likewise also a spoiled sheet can be sent ahead, in order to avoid any soiling. In the printing of the collected print image simultaneously the first print image again is applied from the plate cylinder

10

onto the rubber cylinder

9

.

The printing proceeds in like manner in a printing machine with printing units

28

,

29

according to FIG.

8

. Here print cylinders

27

are constructed as triple-sized cylinders. However, as in the configuration according to

FIG. 7

they collect the print images in each case in pairs from the rubber cylinder

9

. For this reason, here, too, the printing sheets revolve twice with the printing cylinders

27

and the cycling of the sheet feed is executed in correspondence to that described earlier. The more slender sheet conduction is advantageous here, i.e. the printing sheets are not so severely curved. This is desirable especially in cardboard processing.

Furthermore, the printing cylinder

27

is occupied with printing sheets on all working surfaces. With this machine, to be sure, for this reason an advance sheet as soiled sheet is required, since otherwise a printing surface of the printing cylinder would run through empty on the rubber cylinder

5

. This sheet receives consequently only the imprint of one color and must be separated out.

In the configuration according to

FIG. 8

it is further advantageous that further-processing arrangements

30

,

31

on the larger printing cylinders

27

can be engaged directly after the printing units

28

,

29

. As further-processing arrangements

30

,

31

there come in question lacquering mechanisms, numbering mechanisms, imprint mechanisms, stamping, punching, perforating, cutting and grooving devices. In like manner there can also be provided in this place an arrangement for inline quality control.

In the above-mentioned printing units that operate according to the printing cylinder-collecting principle it is also possible to span the printing cylinder or parts of its surface with a rubber blanket. Then, in an intermediate beat one of the two print images, which, to be sure, it must bring up mirror-reversed, can be transferred from the rubber cylinder to the printing cylinder. In the printing then one print image is transferred from the rubber cylinder to the printing sheet and the other from the printing cylinder onto the reverse side of the printing sheet. From this there is yielded a two-side inked print.

In

FIG. 9

there is shown a four-color printing machine with two double printing units

35

,

36

. The printing units

35

,

36

have as special feature the allocation of plate cylinders

37

,

38

with single diameter. Therewith on each printing cylinder

22

there likewise come to be printed two print images in common. Each rubber cylinder

21

transfers, to be sure, only one print image.

The printing mechanisms

35

,

36

allocated to the printing cylinders

22

consist in the example represented therefore of plate cylinders

37

,

38

with single diameter and rubber cylinders

21

with single diameter. The printing occurs then in one passage on the printing cylinder

22

, in which the printing zones lie so far apart that the first printing is concluded before the second begins. The printing cylinder

22

has either one working surface and one gripper row or two working surfaces and two gripper rows, in which one gripper row is drivable for the printing.

These configurations can be varied, as already described under

FIG. 3

, as plate cylinder with doubled diameter can be allocated in each case to the rubber cylinders

21

. Then there can be generated a four-color print per printing passage, in which again two print images per rubber cylinder

21

are collected. Then the machine shown is suited for eight-color printing.

The principle of multicolor printing described is not abandoned either in the arraying on one another of several printing units of the construction type described. The control of the printing machine in starting, or after the passage of the last printing sheet, is analogously the same, in which it is always ensured that no printing ink can pass onto printing material-conducting surfaces. Here, on running-out of the printing assignment a cylinder-setting device can be used in a known manner which makes it possible to disengage the rubber cylinder first from the plate cylinder and then also from the printing cylinder.

As printing processes in such described printing machines there can be used both the conventional offset printing, and also the indirect intaglio printing or relief printing or also the so-called dry offset printing or waterless offset printing. Likewise different printing processes can be combined with one another, so that different working processes are usable simultaneously, in order, for example, to process special inks and lacquers after the printing.

The printing machines are conceived in the simplest possible forms of execution and are especially suited for undertaking automation measures on the plate cylinder. Here the great diameter of the plate cylinder

10

is important. It is thus easily possible to connect numerous image-making arrangements, as feed arrangements of imaged printing forms. Likewise it is easily possible to connect feed arrangements for printing form raw material inside the plate cylinder

10

. The printing plates can be both divided and also combined. This is dependent only on the production expenditure. The arrangements mentioned are not described in detail here, since they are known and were not an object of the invention.
