description

Printing tower of a printing press and a method for providing a footprint of a printing tower of a printing press

The invention relates to a printing tower of a printing press according to the preamble of claim 1 and a method for providing a footprint of a printing tower of a printing press according to the preamble of claim 32.

From DE 198 33 468 A1 discloses a printing unit is known, which is divisible by horizontal displacement of a portion of the printing unit, wherein between the divided parts of the printing unit, a working platform can be raised and lowered and wherein in each case parts of the printing unit are moved, each two forme cylinder contain.

By WO 95/24314 A1 a divisible printing tower is known which has four superimposed double printing units, each directly superimposed double printing units each have the same distance from each other and all

Double printing units can be operated from only one level, and wherein in at least one operating state, a printing material path runs along a transport path which is substantially vertical through the lower two double printing units, around a guide roller and then approximately horizontally between the two central double printing units on one side extends and a second printing material along another transport path on the other side between the two central double printing units into the printing tower, around a guide roller and then passes substantially vertically between the two upper double printing units. Transport paths between medium double printing units run obliquely and around at least two guide rollers.

By WO 2009/043628 A2, a divisible printing tower is known, which at two outside lying sides each having a lift and having a further lift which is movable in an open position of the printing tower between printing tower halves in the vertical direction and at least one at both

Printing tower halves held securing device which is arranged in a working state of the printing tower in a folded position and in a maintenance condition of the printing tower in an extended position. An arrangement height of

Safety device is independent of the vertical position of the other lift.

From DE 42 19 705 A1 discloses a printing tower is known which has four superimposed double printing units and on the two Au ßenseiten each lifting devices are arranged and in which a distance between the middle two

Double printing is larger than respective distances between the two upper and two lower double printing units and in which a printing material along a transport path, which is substantially vertically through the lower two double printing units, to a guide roller and then approximately horizontally between the two average double printing on one side out to the outside and a second printing material along another transport path on the other side between the two middle double printing units into the printing tower, around a guide roller and then substantially vertically between the two upper ones

Double printing passes through.

The invention has for its object to provide a printing tower of a printing press and a method for providing a footprint of a printing tower of a printing press.

The object is achieved by the features of claim 1 and 32, respectively. The achievable with the present invention consist in particular that together with a footprint at least one securing device is arranged, which offers the same protection on each placement height of the stand and yet can be lowered and stowed in a simple and space-saving manner, so that the printing tower by shifting of the side part can be closed. Because the

Securing device is movable relative to the base, it can be placed in a space-saving rest position relative to the base. In a

Embodiment in which the at least one securing device is arranged with respect to their height movable relative to the support surface, there is an advantage that a particularly space-saving arrangement is possible, for example by the stand and the securing device can be arranged under a side frame. A relative pivotability between the base and securing device provides a particularly simple and inexpensive design there. A horizontal pivot axis allows a particularly effective pivoting and reduction.

Another advantage of an embodiment in which the at least one

Securing device and the at least one footprint both together,

in particular jointly, in particular simultaneously and coupled, in particular by means of a common drive are movable, is that the

Securing device is movable together with the base in the vertical direction, and is thus always arranged in an optimal position with respect to an operator located on the floor space. Furthermore, this form of securing device facilitates entry of a gap between the printing tower halves of the open printing tower, because the securing devices can be opened and thus can not unintentionally block a path. The at least one

Securing device can preferably be opened inwardly, whereby a risk of unwanted opening is reduced and safety of operators is increased. Especially at relatively high pressure towers, for example, because of increased distances between printing units, thus an improved security situation is given. A Particularly favorable and secure embodiment can be realized by means of a door which can be swung up to the gap.

Another advantage of an embodiment is that, for example, by an automated moving, in particular folding up the at least one

Securing device relative to the footprint and / or by a controlling machine control, in particular in conjunction with at least one sensor, for example, limit sensor, ensures that a vertical movement of the lifting device is only possible with activated securing device, d. H. when a securing device in a securing position relative to the corresponding

Standing area is located. In addition, a simple operation is possible by the drive. If the drive is arranged below the base, accessibility remains

unrestricted.

A further advantage of an embodiment in which at least one end position sensor is arranged to detect and / or detect at least one position of the securing device is that, on the one hand, it is prevented that the standing surface can be moved without securing to an elevated position and, on the other hand, prevented is that the pressure tower can be closed, although the

Securing device is not yet arranged in a rest position. As a result, hazards to operators, damage to the securing device, the lifting device and the side frames can be prevented.

Another advantage of an embodiment in which the at least one

Securing device is pivotally mounted about a horizontal pivot axis, is that the securing device can be arranged in a rest position relative to the footprint particularly space-saving.

Another advantage of an embodiment in which the at least one Securing device has at least one post and at least one door, is that the securing device is particularly simple and inexpensive and thereby effectively designed.

Another advantage of an embodiment in which at least one drive is arranged below the standing surface, by means of which the securing device is pivotable, is that thereby an automated pivoting is possible and a walk-in area nevertheless fails as large as possible.

Another advantage of an embodiment in which further platforms and / or

Hilfskodeste example, in an Au ßenbereich the printing tower are arranged, is that they telescoped together depending on the position and / or can be moved together with the side frame and thus space saving and yet security bidding are formed.

Another advantage of an embodiment in which a scissor lift is arranged, is that a particularly simple and safe lifting and / or lowering of the base and the securing device is possible. The construction is particularly simple in that the standing surface is preferably movable exclusively in the vertical direction.

Another advantage of an embodiment in which a vertical movement of the at least one footprint is only possible as long as the at least one

Securing device in a securing position relative to the at least one

Stand surface is arranged, is that operators are always optimally protected and not out of convenience, the safety device can be ignored.

Another advantage of an embodiment in which a distance between two adjacent double printing units is greater than a distance between two top double printing units and / or a distance between two lowest double printing units, is that thereby a height of the printing tower is minimized and yet different printing operations are optionally possible, for example, by the fact that the required guide rollers are arranged can. Another possible advantage is that it is possible by this increased distance between corresponding double printing units to pass printing material in the horizontal direction between these double printing units, so that for a deflection from a horizontal direction in a vertical direction or vice versa only one guide roller is necessary and not at least two, as would be necessary, for example, if between the double printing units only room for an oblique course of the Beduckstoffs would be, ie for a course with horizontal and vertical components.

Another advantage of an embodiment in which two fixed levels are arranged with footprints, is that thus for optimum accessibility of

Printing machine is taken care of. This is especially true for lower printing units, as a

Headroom of 200 cm below floor space is feasible. A further advantage is that nevertheless all the advantages of a divisible printing tower with four stacked double printing units can be used.

A further advantage of an embodiment in which a structure of several printing units is largely identical, consists in a simplified and inexpensive construction. Furthermore, this simplifies operation.

Another advantage of an embodiment in which an assembly is rigidly disposed and protrudes through an opening in a side frame, such as a printing tower half, is that an outer footprint may be rigidly disposed while the corresponding printing tower half is moving. Such an opening is preferably formed by two frame parts of a movable side frame and between them Frame parts arranged components of the printing tower, such as ink boxes, cylinders, rollers, etc., in particular transfer cylinder. This can do that

Side frame to be moved and it is still no lifting device necessary to get to upper areas of Au ßenseite the printing tower and there to perform necessary work. Another advantage in this context is that a fixed number of workstations on a printing tower is increased and thereby several operators at the same time on different sides of the printing tower at different heights and thus faster overall maintenance or manual printing form change can perform as if only one height-adjustable workstation were available. Another advantage in this context is that when placing and removing full-width full-circumference printing forms, as for example in a

Semicommercial printing is common, due to a better freedom of movement on the rigid floor space an operator can work better and faster.

Another advantage of an embodiment having an arrangement of a transport path in an area just below a footprint of the printing tower is that thereby an operator below the footprint and below the substrate has enough space to stand upright and work. Another advantage of such a web guide and arranged guide rollers is that a

The web guide does not change when the printing tower is opened, and this avoids complicated adjustments when opening and / or closing the printing tower.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

A printing press 01, which is designed as a rotary web press 01, for example as a rotary web offset press 01, has at least one print substrate 100, at least one printing tower 200, a superstructure 300 with a series of turning bars 301 and at least one folding apparatus 400. Depending on the printing technique used, at least one dryer 500 is arranged, to which, for example, cooling rollers 501 can be arranged downstream. The printing machine 01 may preferably be selected according to the wet offset printing method and / or after the waterless offset printing process. Printing process or dry offset printing process work. Heatset inks and / or coldset inks can be used. The at least one printing material source 100 is preferably in the form of at least one reel changer 100. The at least one printing tower 200 is preferably designed as a divisible printing tower 200, by means of double printing units 201, which are formed from two printing units 201, a web-shaped substrate 02, so a substrate web 02 preferably can be printed on both sides. The printing material 02, which may be, for example, paper 02, is transported from the printing material source 100 along a transport path through the at least one printing tower 200 and printed there and subsequently transported through the superstructure 300 and by means of the turning bars 301 in a preferably freely selectable configuration, for example brought a number of Bedruckstoffsträngen and supplied in this configuration the at least one folder 400 and further processed into individual products. A printing material strand can have one or more layers of printing substrate 02 one above the other.

A printing tower 200 of the printing press 01 comprises at least two side frames 202; 203. These side frames 202; 203 are in one embodiment as printing tower halves 202; 203 trained. These are preferably at least two side frames 202; 203 relative to each other distance variable. Further preferably, a stationary side frame 202 is arranged and a movable, in particular displaceable side frame 203 is arranged relative to this in a first, preferably horizontal direction A movable. The first direction A is preferably perpendicular to rotational axes of arranged in the printing press 01 form cylinders 208. It is also conceivable to arrange a stationary side frame 202 and a plurality of relatively movable side frames 203. Such mobility is ensured for example by sliding surfaces and / or rolling bearings. Movable side frames 203 are particularly movable relative to a foundation, while stationary side frames 202 are fixed relative to the foundation. Each side frame 202; 203 has a plurality of frame parts 204; 206, of which in each case at least one frame part 204 on a first side of at least one printing unit 207 of the Printing tower 200 and at least one frame part 206 on another side of this

Printing unit 207 of the printing tower 200 is arranged. A connecting direction of the frame parts 204; 206 of a respective side frame 202; 203, is preferably parallel to a second direction B, which is parallel to the axes of rotation of the forme cylinder 208.

The printing tower 200 has at least one printing unit 207 and preferably an even number of printing units 207 each having a forme cylinder 208 and a

Transfer cylinder 209. Preferably, in each side frame 202; 203 arranged an equal number of printing units 207 and at least two printing units 207 are arranged one above the other. More preferably, at least six and even more preferably at least eight printing units 207, in particular offset printing units 207 are arranged. The offset printing units 207 are further preferably arranged so that in each case two transfer cylinders 209, one of which a printing unit 207 in the stationary side frame 202 and a printing unit 207 in the movable

Side frame 203 is assigned, are employed in printing operation against each other. The preferably at least six and more preferably at least eight offset chutes 207 thus preferably form at least three and more preferably at least four double printing units 201 arranged one above the other. In this case, each double printing unit 201 preferably has at least two adjoining or engageable transfer cylinders 209, two cooperating with one of the two transfer cylinders 209 forme cylinder 208 and two each cooperating with one of the forme cylinder 208 inking units 21 1. In addition, for example, cleaning facilities and / or

Druckformwechselvorrichtungen and / or, for example, the wet offset printing, per double printing unit 201 two dampening units may be arranged. Such a double printing unit 201 is thus formed from two adjoining or engageable printing units 207, wherein each transfer cylinder 209 of a printing unit 207 as

Counter-pressure cylinder of the other printing unit 207 serve. Preferred are the

Double printing units 201 formed so that rotation axes of each two forme cylinder 208 and at least one, preferably even both transfer cylinder 209 of a Double printing unit 201 lie in a common plane. All are preferred

Double printing units 201 of a printing tower 200 constructed identically at least with respect to an arrangement of respective form cylinder 208 and transfer cylinder 209 and further preferably differ only by their arrangement height. The printing tower 200 is preferably designed as a printing tower 200 of a newspaper printing machine 01.

If in the preceding and / or in the following of distances of the double printing units 201 or the printing units 207 or between the double printing units 201 and the printing units 207 is mentioned, then so is in each case a vertical component of a connecting line between the forme cylinders 208 of the respective double printing units 201 and Printing units 207 meant. In the case of double printing units 201 are each in a same side frame 202; 203 arranged form cylinder 208 meant. At a distance of two printing units 207 or double printing units 201 is, unless otherwise stated, always to understand a vertical distance.

Preferably, at least one, more preferably each pressure tower 200 for

Maintenance work and / or other purposes are shared. Such a division is preferably possible along a substantially vertical separating surface and more preferably between respective pairs of transfer cylinders 209. At this time, the printing tower 200 is changed from a working state in which the printing tower 200 can be in a printing operation and in which the side frames 202; 203 are preferably in contact with each other and more preferably firmly connected to each other, transferred to a maintenance condition. This is preferably done in the form that at least three, preferably at least four superimposed printing units 207 are held stationary with their common stationary side frame 202, while at least three, preferably at least four further superimposed printing units 207 with their common movable side frame 203 substantially in be moved horizontally, preferably in a straight line and more preferably along the first direction A. In the maintenance state so are the printing units 207, in the movable Side frame 203 are arranged, separated from the printing units 207, which are arranged in the stationary side frame 202, and the movable side frame 203 is separated from the stationary side frame 202 (Fig. 7).

In the working state of the printing material 02 is preferably between two

Transfer cylinders 209 arranged at least one double printing unit 201. These two transfer cylinders 209 are in the working state, provided that they each rotate about their axis of rotation, with the printing material 02 in rolling contact. Of the

Working condition does not depend on whether substrate 02 is arranged or not and how wide the substrate is. This means that, in the working state of the printing tower 200, at least one transfer cylinder 209 arranged in the movable side frame 203 has at least one transfer cylinder 209 arranged in the other, stationary side frame 202 and / or with a same

Substrate web 02 as at least one disposed in the other, stationary side frame 202 transfer cylinder 209 is arranged in contact. In the maintenance state, in which the movable side frame 203 in comparison to

Working condition is shifted relative to the stationary side frame 202 in the first direction A, the substrate 02 is not clamped between transfer cylinders 209 of the printing tower 200 and is preferably not in contact with two transfer cylinders 209 of a double printing unit 201. A printing operation is only in the

Working state possible, while in the maintenance condition maintenance

can be performed, for example, on the transfer cylinders 209, which preferably form pairwise printing gaps in the working state, between which substrates 02 are feasible and printable.

Preferably, adjacent printing towers 200 are arranged so that their respective movable side frames 203 are displaced in the same first direction A during the transition from the working state to the maintenance state. It is conceivable, in each case two or more printing towers 200 arranged side by side, in each case completely outside arranged printing towers 200 in such a way that their two movable

Side frames 203 in different directions, each away from each other, ie in or against the first direction A, can be moved to move from the working state to the maintenance state. However, it is disadvantageous if at any point movable side frames 203, for the transition from the working state in the

Maintenance condition to be moved towards each other, since then reduces a horizontal distance between these movable side frames 203 of these printing towers 200 unnecessarily strong. Therefore, with regard to possible extensions of the printing press 01, an opening direction in the first direction A that is the same in all printing towers 200 is expedient and preferred.

The printing substrate 02 is guided in a first printing operation through each of the at least three or at least four printing gaps resulting from pairs of transfer cylinders 209 and printed there by one or preferably both sides. The transport path of the printing material 02 runs essentially in the vertical direction through the printing tower 200.

In a second printing operation, a first printing substrate 02 is located between respective transfer cylinders 209 of at least one and preferably at least two double printing units 201 arranged one above the other and / or there is a second printing material 02 between respective transfer cylinders 209 of at least one and preferably at least two superimposed and above the one or more previously mentioned double printing units 201 arranged double printing units 201. One

Transport path of the first printing material 02 extends in one direction with a greater horizontal than optionally present vertical component and preferably in the horizontal direction at least partially between the uppermost double printing unit 201 and the lowest double printing unit 201 through, preferably at least partially between two double printing units 201 therethrough, neither the top are still the lowest double printing unit 201 to one within the printing tower 200 arranged first guide roller 212 and substantially vertically through at least the uppermost and preferably at least the two uppermost double printing units 201. A transport path of the other printing material 02 in this case runs in one direction with a larger vertical component than possibly present and preferably vertically through at least the lowermost and preferably the two lowermost double printing units 201, around a second guide roller 213 arranged within the printing tower 200 and in one direction larger horizontal than optionally present vertical component and preferably in the horizontal direction, at least partially between the uppermost

Double printing unit 201 and the bottom double printing units 201 through, preferably at least partially between two double printing units 201 therethrough, which are neither the top nor the bottom double printing unit 201. In this printing operation, for example, two printing material webs 02 can each be printed in two colors and on both sides by means of a printing tower 200. In this case, a substantially vertical course is a course which has a component in the vertical direction which is larger than an optional horizontal component. Such a printing operation is shown for example in FIG. 2.

In a third printing operation, for example, a double printing unit 201 can be arranged so that only one printing unit 207 transfers ink and the

Transfer cylinder 209 of the other printing unit 207 serves only as a counter-pressure cylinder. Then, for example, with two double printing units 201, one of which is arranged as described, one side of a substrate 02 two-tone and the other side are printed monochrome.

In one embodiment, at least one printing tower 200 is a number of

Guide rollers 212; 213; 233; 234 arranged such that either in the first or in the second or in the third printing operation with this printing tower 200 can be printed. It is then possible, for example, to arrange a number of printing towers 200 and thus in a printing operation in a part of the printing towers 200, for example in two of the Towers 200 each a web-shaped substrate 02 on two sides to four-color print and in another part of the towers 200 each optionally one or two substrates 02 on two sides each optionally either monochromatic and or two-color print. With an arrangement of four printing towers 200 can be so

For example, in a printing operation with four-page wide cylinders 208 print sixteen pages four-color, twelve pages two-tone and twelve pages monochrome. With the same four printing towers 200 32 pages can be printed in four colors in another printing operation.

The printing tower 200 preferably has at least one, but preferably both of its outer sides with respect to the first direction A, parallel to the sides

Rotation axes of the forme cylinders 208 are located, first and second footprints 214; 216 on. These are, for example, each stationary, so in particular neither in the vertical direction nor in the horizontal direction in a relative movement of the

Side frames 202; 203 movable to each other. The first and second footprints 214; 216 are each preferably connected to at least one staircase 217 or ladder 217 such that an operator via these ladders 217, the first and second standing surfaces 214; 216 can reach from a higher or lower position. First footprints 214 are arranged so that an operator located thereon can reach printing units 207 in communication with the stationary side frame 202 both in the working condition and in the maintenance condition. Second floor surfaces 216 are arranged so that an operator located on them can reach printing units 207, which are in communication with the movable side frame 203, both in the working state and in the maintenance state. The first and second footprints 214; 216 are disposed at a height which is at least above a rotational axis of the lowermost forme cylinder 208 of the

Pressure tower 200 and below an axis of rotation of the uppermost plate cylinder 208 of the printing tower 200 is located. But it is also possible that the first and / or second standing surfaces 214; 216 variable in height and / or with the movable Side frame 203 in the first direction A are movable.

The first footprint 214 is assigned to the stationary side frame 202 and the second footprint 216 is assigned to the movable side frame 203. The first, stationary base 214 is preferably rigidly connected to the stationary side frame 202, more preferably such that the first base 214 is not pivotable about an axis. The second footprint 216 is, if it is arranged stationary, preferably not rigidly connected to the in and against the first direction A movable side frame 203, but held stationary by means of brackets 219 and / or supports 221. The fixed second footprint 216 may also be rigidly connected to other stationary machine components, such as a fixed side frame 202 of an adjacent printing tower 200 and / or the stationary side frame 202 of the own printing tower 200. The second footprint 216 is relative to the printing units 207 of the movable Side frame 203 arranged such that a part of the printing units 207 of the movable side frame 203 is preferably completely below the second footprint 216 and another part of the printing units 207 of this movable side frame 203 is preferably completely above the second footprint 216. Preferably, one half of the printing units 207 is located above the second base 216 and the other half of the printing units 207 below the second base 216, more preferably, at least two double printing units 201 are located below the second base 216.

Under a printing unit 207, which is located below, for example, the second footprint 216, a printing unit 207 is to be understood, which has only those rotatable components whose axes of rotation are in the vertical direction below the second footprint 216, regardless of a horizontal position of this

Rotation axes with respect to the second footprint 216. The same applies to a position above or over, for example, the second footprint 216. In one embodiment, an assembly 218 that is at least a second

Stand surface 216 and brackets 219, in the working state and / or in the

Maintenance state arranged such that this assembly 218 protrudes through a movable opening, the side of two frame parts 204; 206 of the movable side frame 203 and up and down of two on each of these two frame parts 204; 206 fastened components is limited. In addition, the assembly 218 is preferably rigidly connected to at least one and more preferably on both sides of this opening with respect to the first direction A with at least one stationary component of the printing press 01. Such stationary components may be, for example, the fixed first side frame 202 or supports 221 which are rigidly connected, for example, to a floor or a stationary machine frame part. The above, on the frame parts 204; 206 fastened components can any, between the frame parts 204; 206 running components, such as ink boxes and / or ink rollers and / or friction rollers and / or forme cylinder 208 and / or transfer cylinder 209 and / or dampening and / or cleaning devices and / or stabilizing trusses. The opening is movable insofar as upon movement of the movable side frame 203, both frame parts 204; 206 and just such rigidly connected components to be moved. The opening is preferably located below the uppermost double printing unit 201 and above the lowermost double printing unit 201 (FIGS. 6 and 7).

In any case, it is possible in this way, to move the movable side frame 203 in the transition from the working state to the maintenance state in the first direction A, that at least a portion of the second footprint 216, the

Operating state of an operator is accessible, is arranged in the maintenance state between components of two printing units 207, of which a printing unit 207 is located above the second base 216 and the other printing unit 207 under the second base 216.

This results in a method for dividing the printing tower 200, in which at least a movable side frame 203 of the printing tower 200 is moved relative to at least one stationary side frame 202 of the printing tower 200, the second standing surface 216, after dividing the printing tower 200, projecting into the opening laterally through the two frame parts 204; 206 of the at least one movable side frame 203 and up and down of two of each of these two frame parts 204; 206 fastened components is limited and wherein the second footprint 216 and / or the second footprint 216 rigidly connected or the second footprint 216 containing assembly 218 has not before or less widely and / or with another section in this opening has called.

If arranged, the first and second guide rollers 212; 213 is preferably arranged on the stationary first side frame 202 and / or on the component 218, so that upon displacement of the second side frame 203, these first and second guide rollers 212; 213 do not change their situation. In another embodiment, one or both of these guide rolls 212; 213 arranged on the movable second side frame 203, so that upon movement of the second side frame 203, each corresponding first and / or second guide roller 212; 213 is also moved and thereby an area between the side frames 202; 203 is completely free, for example, at least a third footprint 223 in the vertical direction between the side frames 202; 203, for example by means of a lifting device 222.

In the following, a third standing surface 223 is mentioned, but all the information relates to at least one third standing surface 223. For example, it is conceivable to arrange a plurality of third standing surfaces 223 in a direction parallel to a rotation axis of a forme cylinder 208. These can also be independent

operated by each other. Preferably, however, is the case in which a single third footprint 223 per printing tower 200 is arranged. The lifting device 222 can also be lifted in the case in which the first and second guide rollers 212; 213 are arranged rigidly, for example only up to a certain height at which the lifting device 222 and the first and / or second guide rollers 212; 213 neither touch nor hinder in any other way. The lifting device 222 can be raised so far that a

Operator from the third base 223 can easily access the topmost printing unit 207 of the printing tower 200. The lifting device 222 can be lowered so far that the third base surface 223 is lowered so far that the printing tower 200th

can be closed. If, in the following, the standing surface 223 is mentioned, in particular in connection with the lifting device 222 and / or at least one securing device 224, then the third standing surface 223 is meant, unless otherwise stated. The lifting device 222 preferably has a lifting drive, for example at least one hydraulic cylinder and / or an electric motor. The lifting drive is preferably machine-controlled. The lifting device 222 also has guides, for example in the form of rails, articulated arms, gear bars, etc. Preferably, the lifting device 222 has at least one

The lifting device 222 and in particular its lifting drive is preferably connected to a higher-level machine control, for example in the form that the machine control determines or at least forwards a desired height of the lifting device 222 and / or that the machine control of the

Lifting device 222 receives and / or contains data about a respective actual height.

Preferably, the lifting device 222 is designed in the form of a lifting platform 222, which has a third base 223. The third footprint 223 is movable in the maintenance state of the printing tower 200 in the vertical direction and / or in a space between the side frames 202; 203 of the printing tower 200 arranged. Of the

The base 223 and the at least one securing device 224 are components of the lifting device 222 and preferably by means of a common drive in the vertical direction movable. The at least one security device 224 is thus together, in particular designed to be movable together with the base 223 in the vertical direction. This means in particular that a movement of the base 223 brings about a simultaneous and similar movement of the securing device 224. The at least one securing device 224 is arranged to be movable relative to the standing surface 223. In a superposition of a movement of the base surface 223 and a movement of the at least one securing device 224 relative to the

Standing surface 223, the movement of the securing device 224 is not always uniform to that of the base surface 223, a movement of the base surface 223 without movement of the at least one securing device 224 is not possible. In particular, the at least one securing device 224 can be arranged and / or arranged in a rest position relative to the base surface 223 and / or in a securing position relative to the base surface 223. In particular, the at least one securing device 224 is arranged movable relative to the standing surface 223 with respect to its height. This means that at least some or all of the at least one securing device 224 in the securing position relative to the standing surface 223 is arranged at least partially at a greater height with respect to the standing surface 223 than in the rest position of the at least one securing device 224 relative to the standing surface 223.

Furthermore, this is characterized in that the standing surface 223 is arranged in the lower rest position outside a range of movement movable side frames 203. In the lower rest position, the footprint 223 below the movable side frame 203 and / or between Rack parts 204; 206 of the movable side frame 203 may be arranged and / or be arranged. The stand surface can be arranged and / or arranged in at least one raised working position. This is preferably characterized in that it represents a higher position than the lower rest position. In the at least one raised working position of the standing surface 223, this provides access to upper printing units 207. The standing surface can be moved between the lower rest position and the raised working position in at least vertical and preferably exclusively vertical direction, but preferably only when the securing device 224 in the securing position relative to the base 223 is located. This results in different possible configurations of printing tower 200, base 223 and securing device 224.

In the working state of the printing tower 200, the standing surface 223 is arranged in the vertical direction at least partially and preferably completely below at least one printing unit 207 arranged in the one movable side frame 203. Preferably, in the working state of the printing tower 200, the standing surface 223 is arranged in the vertical direction under at least one in the one, movable side frame 203

Printing tower 100, the base 223 arranged in the lower rest position and is at least one securing device 224 in the rest position relative to the base 223rd

In a first operating state, which is preferably a transitional state, the printing tower 200 is in the maintenance state and the standing surface 223 is arranged in the lower rest position and the at least one securing device 224 is in the rest position relative to the base surface 223.

In a second operating state, which is preferably an open state, the printing tower 200 is in the maintenance state and the footprint 223 is in the lower one Arranged resting position and is at least one securing device 224 in the securing position relative to the base 223th

In one embodiment, the at least one securing device 224 is in

Working state of the printing tower 200 arranged folded. This corresponds to the

Rest position of the at least one securing device 224 relative to the base surface 223. For this purpose, the at least one securing device 224 is pivotally arranged with respect to the third standing surface 223, preferably at least one pivot axis, which is more preferably horizontal and even more preferably parallel to the first direction A, ie perpendicular to the second direction B of the axes of rotation of the forme cylinder 208 runs. Preferably, the at least one securing device 224 in each case has at least one post 226 which, as described above, is preferably pivotable relative to the third standing surface 223. At least one door 227 is arranged at such posts 226, which is preferably pivotable about a substantially vertical axis when the post 226 is folded up, that is to say substantially vertically arranged. This corresponds to the securing position of the at least one securing device 224 relative to the standing surface 223. For this purpose, the at least one door 227 is preferably fastened to the at least one post 226 by means of at least one hinge. The at least one door 227 may, for example, as a surface or preferably as a light A door 227 is preferably part of a reinforcement 224 and / or a railing part 224. Preferably, the at least one securing device 224, in particular the at least one door 227, can only be turned inwards, ie on the space between the

Printing tower halves 202; 203 or side frames 202; 203, open, in particular, swing open. This is further preferably only possible as long as the at least one securing device 224 is in the securing position relative to the base 223, ie in particular only as long as the at least one post 226 is arranged in an upright, secured position, in particular only in the maintenance state of the printing tower 200 (FIG. Figs. 8, 9 and 10). A device is preferably arranged which ensures that a door 227 of a vertically standing securing device 224 is automatically brought into or held in a closed state, for example a torsion spring. In this way, a protective effect of

Operators improve and ensure that the door 227 is always closed when the securing device 224 is to be pivoted to close the printing tower 200.

The at least one post 226 is preferably pivotably mounted via at least one hinge, that is to say about a preferably horizontal pivot axis. The at least one

Securing device 224, in particular the at least one post 226, is preferably connected to at least one drive 228, for example a hydraulic cylinder 228, arranged preferably below the third standing surface 223. The drive 228 is preferably machine-controlled, more preferably with a superordinate one

Machine control circuit connected. In this way, the

Safety device 224 can be opened automatically controlled by a machine control. Preferably, at least one sensor, more preferably at least one end position sensor is arranged, the at least one layer of at least one

Securing device 224 is arranged to detect and / or detectable, preferably at least one position of the at least one securing device 224 relative to the Stand surface 223. More preferably, at least two such sensors are arranged, of which at least one is designed as an end position sensor and a rest position and / or a securing position of the securing device 224 relative to the

Stand surface 223 is arranged detecting and / or detectable. A

Secured position corresponds for example to a state in which the post 226 is preferably arranged vertically and the door 227 can be opened. A rest position corresponds for example to a state in which the post 226 is arranged horizontally, so that with a correspondingly low arrangement of the base surface 223 and the

Lifting 222 a closing of the printing tower 200 is possible. As long as the securing device 224 is located neither in the securing position nor in the rest position relative to the Stanfläche 223, preferably neither the printing tower 200 closed nor the base 223 can be moved in a vertical view for safety reasons. This is preferably ensured by the fact that the drive 228 is connected to a higher-level machine control.

In one embodiment, the drive 228 is disposed on a lever of the securing device 224 located on a different side of the pivot axis than a portion of the securing device 224 disposed above the third standing surface 223. In another embodiment, the drive 228 is on a lever of the securing device 224 arranged on the same side of the pivot axis, as a above the third footing 223 arranged part of the securing device 224th

This results in a method for providing the third footprint 223 of the printing tower 200 of the printing machine 01, wherein the printing tower 200 is divided by moving at least the movable second side frame 203 relative to at least the stationary first side frame 202 and thereby the space between the side frames 202 ; 203 is created and where in the space

arranged and exposed by the movement of the second side frame 203, lifting device 222, the third footprint 223 in the space in vertical Direction transported to a desired position and wherein after the displacement of the second side frame 203, and preferably before the carriage of the third

Standing surface 223, the at least one securing device 224 is moved relative to the support surface 223, preferably by means of a drive 228 and wherein the at least one securing device 224 is moved together with the support surface 223 in the vertical direction, preferably by means of a lifting drive. Preferably, the at least one securing device 224 is moved from a horizontal position to a vertical position

pivoted.

A further step of the method is then that with movement of the movable side frame 203 relative to the other side frame 202, the printing tower 200 is transferred from a working state to a maintenance state. A further step of the method is then that the at least one

Securing device 224 is moved relative to the base surface 223 and is thereby transferred from a rest position to a securing position. A further step of the method is then that then the stand surface 223 and the at least one securing device 224 are moved in the vertical direction and is thereby transferred from a lower rest position to an increased working position.

A further step of the method is then that for panning the

Securing device 224, the drive 228 moves a lever, so that this lever is pivoted about the pivot axis and the located on another or the same side of the pivot axis of the securing device 224 is thereby also pivoted. A further step of the method is that after the securing device 224 has been pivoted into a vertical position, the at least one door 227 of the securing device 224 is pivoted relative to the at least one post 226 and allows access to the third standing surface 223. It is also conceivable that the third base surface 223 is first brought into an intermediate position in which the at least one securing device 224 in the securing position relative to the base 223 is transferred and that subsequently a further movement of the third footprint 223 in the vertical direction is possible.

In one embodiment, a vertical distance is between two adjacent ones

Printing units 207 of a side frame 202; 203, which are both below the uppermost printing unit 207 and above the lowermost printing unit 207, greater than the vertical distance between the two lower printing units 207 of the same

Side frame 202; 203 and / or greater than the vertical distance between the two upper printing units 207 of the same side frame 202; 203, for example by at least 10 cm and at most 80 cm, preferably at least 15 cm and at most 40 cm. In this way, it is possible to make this larger vertical distance the corresponding two printing units 207 so large that the second

Standing surface 216 fits between them and / or that in the second printing operation of the substrate 02 can also be passed between these two printing units 207 in the horizontal direction (Figures 1, 2, 5 and 7). This applies to both in the stationary side frame 202 and arranged in the movable side frame 203 printing units 207, since they must be to form the double printing units 201 at appropriate heights. Preferably, the distance between the two lowest printing units 201 is the same size as the distance between the two uppermost printing units 201.

Preferably, the first and second footprints 214; 216 arranged at such a height that an operator can work safely and preferably upright under them and that another operator can continue to work safely and preferably upright on them. Preferably, treads, such as fold-out treads are arranged to ensure that an operator can reach all parts of the printing tower 200. Treads differ, in addition to their size, especially by the first and second footprints 214; 216 that the treads are pivotally mounted about an axis, while the first and second footprints 214; 216 are not arranged pivotally.

If two printing towers 200 are arranged next to one another, a single, common base 214 is preferred between them; 216 arranged. This common

Standing area 214; 216 then forms an access to printing units 207 of both printing towers 200, both in the working state and in the maintenance state of one or both adjacent printing towers 200. The common footprint 214; 216 may be in contact with one or both of adjacent printing towers 200 and is preferably rigidly connected to an adjacently disposed stationary side frame 202. The common floor space 214; 216 then corresponds to a combination of the first

Stand surface 214 of the one printing tower 200 and second footprint 216 of the other printing tower 200th

Preferably, a common base 214; 216 between two printing towers 200 an opening 232, is transported through the substrate 02 in the vertical direction. In a direct vicinity of such openings 232 are preferably each third

Guiding rollers 233 arranged, which provide an orderly transport path of the printing material 02. Also first and second footprints 214; 216, not between two

Printing towers 200 are arranged, may have such openings 232, in this case, but it would also be possible substrate 02 outside the first and second footprints 214; 216 to transport vertically.

A web guide is then designed, for example, so that a first printing substrate 02 in a position with a greater horizontal than possibly existing vertical

Component at least partially between a forme cylinder 208 of the uppermost and a forme cylinder 208 of the lowermost double printing unit 201, around a first guide roller 212 disposed within the printing tower 200 and in one direction with a larger vertical than optional horizontal component between each two transfer cylinders 209 at least the uppermost one Duplex printing unit 201 is disposed therethrough, wherein another substrate 02 in a position with a larger vertical than optionally horizontal component between each two transfer cylinders 209 at least the bottom double printing unit 201 therethrough, disposed within the printing tower 200 second guide roller 213 and in one direction larger horizontal than optionally present vertical component at least partially between a forme cylinder 208 of the uppermost and a forme cylinder 208 of the lowermost double printing unit 201 extends therethrough and wherein the first substrate 02 another, fourth guide roller 234 is arranged in a loop, which is arranged at a height which is from the height at which the first guide roll 212 is located is less than 50 cm and preferably less than 25 cm, and wherein this fourth guide roll 234 is less than 50 cm and preferably less than 25 cm in the vertical direction below a first and / or second footprint 214; 216 of the printing tower 200 is arranged. Height indications and distances with respect to the guide rollers 212; 213; 233; 234 relate to respective locations of corresponding axes of rotation.

Preference is given in the working state of the printing tower 200, in which the

Printing tower 200 is closed, both substrates 02 with at least one transfer cylinder 209 of the stationary side frame 202 and at least one transfer cylinder 209 of the movable side frame 203 in contact. Preferably, in the maintenance state of the printing tower 200, in which the printing tower 200 is open, both printing materials 02 are not with transfer cylinders 209 of the movable

Side frame 203 in contact.

It is preferred that the first printing material 02 previously by an opening 232 in the first and / or second or common footprint 214; 216 is moved and / or that the second substrate 02 subsequently through another opening 232 in the or another first and / or second or common footprint 214; 216 is moved. Preferably, between adjacent towers 200 in areas that are not disposed between form cylinders 208 of adjacent towers 200, platforms 229 and / or deployable sub-stands 229 are arranged, which are further preferably designed so that their respective area can be reduced, for example in the manner of a Telescope, so that a displacement of a corresponding movable side frame 203 is not hindered. Stairs 217 and ladders 217 are preferably rigidly connected to such components of such platforms 229 or auxiliary platforms 229, which are arranged rigidly relative to the stationary side frame 202, but may also be designed to be movable. It is also possible to arrange auxiliary platforms 229 in areas which are not reduced by a movement of the movable side frame 203, but which nevertheless require a mobility of these auxiliary platforms 229. These auxiliary platforms 229 are then preferably rigidly mounted relative to the movable side frame 203 and thus movable relative to the stationary side frame 202 (Figures 3 and 4).

Preferably, printing towers 200 are divisible as described above, with two

Side frames 202; 203 are separated from each other, wherein also of printing tower halves 202; 203, although not necessarily an exact halving of the

Printing tower 200 enters. But it is also conceivable that a printing tower 200 is divided into more than two parts, so that, for example, a stationary side frame 202 stops and two movable side frames 203 are moved away from it. In doing so, I let everything described above be transmitted analogously, for example, each of these lateral adjusting parts 202; 203 at least in a maintenance state having an opening into which in each case one or a total of a rigidly arranged assembly 218 projects at least partially. It can then also be arranged in the spaces between the stationary side frame 202 and the movable side frames 203 each have a lifting device 222. An arrangement of the double printing units 201 with respect to a vertical direction is compared with that described above unchanged.

Preferably, a printing tower 200, the four arranged one above the other

Double printing units 201 has a dimension in the vertical direction, which is at least 390 cm and at most 470 cm. In this way, it is ensured that both on a level corresponding to the floor and the accessibility of at least the two lowest double printing units 201 serves, as well as on a plane which the first and / or second and / or third footprint 214; 216; 231 corresponds and the accessibility of at least the top two printing units is used, there is enough space for an operator to work safely. The dimension in the vertical direction refers to a distance between the bottom and highest point of the side frames 202; 203. Any areas for sinking the lifting device 222 are added.

Preferably, juxtaposed towers 200 of a printing press 01 have such dimensions and spacings that a plane defined by the print gaps between the transfer cylinders 209 of the one print tower 200 is one of the print gaps between the transfer cylinders 209 of an adjacent one

Pressure tower 200 fixed level have a distance of at least 420 cm and at most 520 cm. A distance between side frames 202 facing each other; 203 adjacent, closed printing towers 200 is preferably at least 240 cm and at most 340 cm.

Shaping cylinders 208 may have extensions in the direction of their axes of rotation, making it possible to print at least two double-width newspaper pages and at most six double-wide newspaper pages. In principle, even smaller or even larger expansions are possible.

An axis of rotation of a lowermost transfer cylinder 209 of a stationary Side frame 202 and a rotation axis of a lowermost transfer cylinder 209 of a movable side frame 203 have a first distance in the working state of the printing tower 200 and have a second distance in the maintenance state of the printing tower 200. The first distance is smaller than the second distance, in particular with respect to respective horizontal components of the first and the second distance.
