Description

The invention relates to a device for guiding a part-width web in a processing machine with a guide element according to the preamble of claim 1.

In production or processing machines, z. As printing presses, the material webs to be produced or processed are often cut longitudinally on their way through the machine, and then fed the resulting partial webs further processing stages. For this purpose, the partial webs are guided over guide rollers of different design, which z. T. extend over the entire width of the machine. Such long guide rollers are then to avoid deflection to design accordingly strong and have a correspondingly large inertia. In contrast, however, a partial web touches or wraps around only part of the length and has a much smaller cross-section compared to the entire web. These two effects cause especially during startup or z. As in control or production-related speed changes increased fluctuations in the sub-web and thus quality degradation in the product or even web break.

The WO 01/70608 A1 discloses a turner bar assembly, wherein two substantially part-wide turning bars are each arranged displaceably on a carrier transversely to the direction of the incoming partial web. In each case laterally outside of the side frame, a register roller is arranged, whose longitudinal axis extends substantially parallel to the side frame and which is also displaceable along a rail in a direction transverse to the direction of the incoming partial web.

By the DE 36 02 894 C2 is a designed as a register roller guide element disclosed, which is variable in its position and thus designed to change the pathway.

In the GB 1 546 798 is a frame having a plurality of turner bars and a plurality of register rollers, movable overall laterally to the incoming web. To accommodate different lane pitches, this entire frame is interchangeable.

In the GB 594,035 discloses a guide roller for already longitudinally folded strands downstream of the former, which has a plurality of individually rotatable roller sections on the strand width.

The invention has for its object to provide a device for guiding a part-width web in a processing machine with a guide element.

The object is achieved by the features of claim 1.

The achievable with the invention advantages are, in particular, that with simple means a web transport with desired and predeterminable speeds and web tension is guaranteed even for partial webs. By the device inertial effects are minimized, which in the management of partial webs on non-driven, over the entire possible web width reaching guide elements, such. B. guide rollers, would cause. The above-described influences on quality and safety are minimized.

The arrangement of two guide elements on a common carrier allows for a common movement of the two guide elements without having to make a realignment to each other in production change basically. The arrangement of two vanes at least on a common guide saves space and allows short paths of the partial webs.

In some embodiments, it is also possible to shorten the railways and to avoid a repeated overturning of the partial web with simple turning of the partial web.

It has been created against each individually movable guide elements a significantly cheaper and easier to handle solution.

Especially in connection with double-wide and especially triple-width printing presses, the device is of great advantage, since continuous guide elements have a particularly large inertia due to the large width (and resulting large cross-section). Also can be saved in particular in the above printing presses required by outwardly displaced register rollers space.

In an advantageous embodiment, the register roller, which is oriented with its axis of rotation perpendicular to a plane of the side frame or parallel to cylinders of a printing unit, and / or the harp roller assigned to the same sub-web, is designed partially in the superstructure.

In an advantageous embodiment, all, a same and individual sub-orbit associated unthreaded guide elements between longitudinal cutting device and a first, the funnel associated Zug- or funnel inlet roller partially or as a split roller with several independently rotatable sections in the axial direction.

For double wide printing presses, the uncut, full web is merely one such device, two of these in the case of triple wide printing presses Devices required.

Compared to a double-width printing machine with the same target strength of a product to be achieved, the production reliability of the printing press is further increased due to less required aggregates and the investment is further reduced with a triple-wide design of the printing units. While maintaining the number of printing units, however, the output of the printing press, or each printing unit can be increased by 50%.

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

In the Fig. 1 The web-fed rotary printing press shown by way of example has a left and a right section, each having at least two printing towers 01. The printing towers 01 have printing units which z. B. three times wide, ie for the printing of six axially juxtaposed newspaper pages executed. The printing units are designed as satellite printing units with at least two respective transmission cylinders assigned to a common satellite cylinder and in each case one forme cylinder interacting with the transfer cylinder. The advantageous embodiment of the printing units as nine-cylinder satellite printing units ensures a very good Passerhaltigkeit or a low fan-out. However, the printing units can also be designed in other ways.

The transfer cylinder has in each case a circumference, which corresponds to at least two circumferentially successively arranged stationary newspaper pages. The forme cylinder can also advantageously have a circumference which corresponds to at least two stationary newspaper pages arranged one behind the other in the circumferential direction.

Between the sections two Falzaufbauten 02 are arranged, which z. B. each have arranged on two different superposed planes folding former. However, the printing machine can also have only one common folding structure 02 arranged between the sections, or else only one section and an associated folding structure 02. Also, the respective Falzaufbau 02 can be performed with only one level of formers. Each Falzaufbau 02 are associated with one or more folders 03. The printing units, the web is fed by rollers, not shown, in particular using reel changers.

Above the printing towers 01 a superstructure 04 is provided per section, in which tracks cut at longitudinal cutting devices 06, partial webs by means Turning devices 07 possibly offset and / or fallen, by means of in Fig. 1 Not shown register devices are aligned in the longitudinal register to each other and can be performed on top of each other. In Fig. 1 Guides 08 are indicated at which, not shown, described below carrier for the lateral movement of turning bars 07 and possibly register device can be arranged. As seen in the web running direction, the superstructure 04 in front of one of the stacking hoppers arranged one above another has a roller group 09 defining the funnel inlet of webs, a so-called harp 09 with a plurality of guide elements designed as harp rollers. To save height, only one harp 09 is arranged in the example for two superposed formers of which webs on one and / or the other of the superposed formers are feasible. It is only arranged in front of the upper former.

As harp rollers, the group of rollers is understood below, which represent the last non-driven guide rollers in front of the hopper inlet in the direction of the webs. They are usually the last (non-driven) rolls, which are assigned to only one printing material layer. Thereafter, for example, a plurality of webs or partial webs combined into a strand and, for example via the Zug- 13 and / or funnel inlet roller 14 (see Fig. 2 ).

The in Fig. 2 shown Falzaufbau 02 for the triple-wide printing machine has z. B. three juxtaposed lower former 11 and three overlying each other and juxtaposed upper former 12 on. The formers 11; 12 each upstream train 13 and funnel inlet rollers 14 have in an advantageous embodiment as well as the folder 03 and provided in Falzaufbau 02 pull rollers (in Fig. 2 only by partial filling of the respective draw rollers) each have their own drive motors 16.

The above Falzaufbau 02 with only one harp 09 for two on top of each other arranged folding hopper and the elements of the superstructure 04 described in more detail below are also suitable for other printing presses with different cylinder widths and cylinder circumferences, even if Falzaufbau 02 and 04 superstructure are shown using the example of the triple wide printing press.

Fig. 3 shows in a perspective oblique view a first embodiment for at least a part of the superstructure 04. A whole web 17, ie, for example, a web 17 having a width which is six in the case of a double wide printing press substantially four, and six in the case of a triple wide printing press is juxtaposed standing newspaper pages, is fed to a longitudinal cutting devices 06. This has z. B. a draw roller 18, with which pressure rollers can work together to avoid slippage. On the lateral surface of the tension roller 18 are knives 21 can be adjusted to the web 17 as required in part-width webs 22; 23; 24, in particular in partial webs 22; 23; 24 to cut ( Fig. 4 ).

Partial width webs 22; 23; 24 can be supplied to the superstructure 04 without longitudinal section, in which the printing press or a printing tower or a printing unit already has a part-width track 22; 23; 24 is supplied. This then has z. B. a width which is much smaller, z. B. at least ¼ smaller (eg double wide machine) or at least 1/6 smaller (triple wide machine), as a maximum printable by the printing unit width. Also in this sense, the following remarks on the part-track-wide guide elements (see below) are to be understood.

The partial webs 22; 23; 24 are in Fig. 4 shown narrower and spaced apart for the purpose of better illustration. Exemplary is in Fig. 4 the partial web 24 as a straight-ahead partial web 24, the partial web 23 as turned from the center to the outside partial web 23 and the partial web 22 is shown only incomplete. The partial web 22 could, for example, like the partial web 24 out straight, or by means of a second such turning device 07 as the partial web 23 in another To be turned away. A second turning device can lie above or below the plane defined by the partial web 23 entering the first turning device 07.

A like the sub-web 23 cut and then staggered, turned and / or fallen sub-web 23 experiences with respect to the other sub-webs 22; 24 an offset in the direction of the partial web 23 and must therefore be corrected by means of a register means 26 in the longitudinal register. Since this offset relates specifically to this cut partial web 23 and is bound to its web guide, the register device 26 will now at least one of the course of the partial web 22; 23; 24 determining web guide elements, such. B. the turning device 07 or the harp 09 assigned.

In Fig. 3 and 4 the register device 26 is structurally at least one turning bar 28; 30 running guide element 28; 30 associated with the turning device 07, which imprints the partial web 23 a change in direction. The register device 26 and at least one of the turning bars 28; 30 are on a common carrier 25; 27, which is arranged in a plane parallel to the plane of the incoming partial web 23 transversely to the running direction movable on one or more guides 08. The parts of the register device 26 and the turning device 07 which cooperate with the part web 23 are dimensioned transversely to the running direction in their width such that their projection essentially corresponds to the width b23 of the incoming part web 23.

The turning device 07 points in Fig. 3 and 4 a pair of parallel turning bars 28; 30 on which z. B. each on its own carrier 25; 27 are arranged at an angle of approximately 45 ° to the direction of the incoming part of web 23. The turning bars 28; 30 may be provided in the region of its lateral surface with openings for an outgoing air flow and / or with a friction-reducing surface. You can on the carrier 25; 27 about an axis perpendicular to the plane, or about an axis be pivotable or mountable parallel to the direction of the incoming partial web 23.

On the support 27 upstream of the turning device 07 and before the first-turned turning bar 30, the register means 26 is arranged, which on a frame 29 with respect to the frame 29 fixed roller 31, z. B: guide roller 31, and a relative to the frame 29 parallel to the direction movable roller 32, z. B. Register roller 32, has. If the carrier 27 is moved along the guides 08, the turning device 07 and the register device 26 can simultaneously move into a different alignment, ie. H. in the path of another sub-web 22; 24 are brought. Since the turning bar 30 and the register device 26 are fixedly connected to the carrier 27, neither their basic orientation is to be readjusted to each other, nor it requires two steps and / or two drives.

The two turning bars 28; 30, when they are each on a support 25; 27 are arranged, independently of each other on the respective guides 08 movable. Thus, a displacement can take place over one or two partial web widths, depending on the relative position of the turning bars 28; 30. However, it is also possible, both turning bars 28; 30 on a common carrier 25; 27 to arrange.

If only one turning bar 30 is arranged on the carrier 27 common to the register device 26, then this must be the turning bar 30 first circulated after the register device 26. The second turning bar 28 can then optionally be arranged on the own carrier 25. This further carrier 25 may optionally be arranged on the same guides 08, and possibly driven together with the carrier 27 or separately.

The expiring partial webs 22; 23; 24 can either over a provided for the wide web 17 wide register roller 33 and wide guide roller 34 a wide, not in Fig. 3 or 4 shown harp roll are supplied, or as shown directly to a subdivided in their longitudinal direction harp roller 36 with sections 37 are performed. Number and length L37 of the sections 37 substantially correspond to the number and the width b23 of the possible partial webs 22; 23; 24th

In an advantageous development, in the superstructure 04 of a three-wide printing press, each such entire web 17 has two such registers and turning devices 26; 07 equipped carrier 27 provided (as in the embodiment according to Fig. 6 and 7 but transferred to Fig. 3 and 4 ).

The carrier 25 may as in Fig. 4 shown to be executed substantially with a width b25, which corresponds approximately to the width b23 of a partial web 23. In the case of both turning bars 28; 30 jointly carried carrier 25; 27, he can also in about the width b23 of two partial webs 22; 23; Have 24 and possibly staged executed each turning bar 28; 30 may be arranged on guides 08 on vertically offset planes. The two turning bars 28; 30 are thus automatically arranged on different levels as desired. The embodiment with the width b23 of two partial webs 22; 23; 24 may be advantageous for the standardization of the carrier 27, if it is to be carried out with mutually orthogonal turning bars 28, as shown below Fig. 5 is shown.

In the following variants and embodiments, the reference numerals for repetitive parts are retained. The detailed description as well as the function is not listed again and must be transmitted alternately. Also the partial webs 22; 23; 24 are no longer shown in the sense of a better overview, but indicated as required by the solid line symbolizing the corresponding partial path (as well as in FIG Fig. 3 shown).

The turning bars 28; 30 in a variant of the first embodiment according to Fig. 5 are orthogonal to each other and allow falling of the sub-web 23. The sub-web 23 is after passing through the register means 26 first to one of the turning bars 28; 30, then guided around a first roller 38, wherein a first contact line on the lateral surface thereof with the incoming partial web 23 substantially in a common plane with a contact line on the lateral surface of the first turned turning bar 28; 30 lie with the expiring partial web 23. The subsequently circumscribed second roller 40 is arranged in such a way that a last contact line lies on its lateral surface with the outgoing partial web 23 substantially in a common plane with a first contact line on the lateral surface of the second turner bar 28. The axis of rotation of the rollers 38; 40 are perpendicular to the axis of rotation of the tension roller 18. Finally, the partial web 23 is guided around the second turning bar 28. Depending on the position of the turning bars 28; 30 to each other in a direction transverse to the incoming part of the web 23, the sub-web 23 is additionally turned into a different flight. No turning takes place when the two turning bars 28 intersect in the region of the center line of the incoming partial web 23. In Fig. 5 the partial web 23 is supplied by way of example to a wide, continuous harp roller 39. The too Fig. 4 and 5 variants described are mutually interchangeable.

In a second embodiment ( Fig. 6 and 7 ) is the partial web width register means 26 structurally not the turning device 07, but a partial web width, with its axis of rotation perpendicular to the direction of the incoming part web 23 extending guide element 41, z. B. a roller 41, in particular z. B. a harp roller 41 assigned.

As in Fig. 6 is shown, the register means 26 with its frame-fixed roller 31 and the movable roller 32 is arranged on a along at least one guide 42 transversely to the direction of the incoming partial web 23 movable carrier 43. In addition, the harp roller 41 is arranged downstream either on a separately connected to the carrier 43 frame or on the extended frame 29, which a Length L41 which corresponds to the width b23 of the partial web 23 substantially. If now the carrier 43 is moved along the guides 42 transversely to the running direction, the register device 26 as well as the partial-web-wide harp roller 41 can simultaneously move into a different alignment, ie into the path of travel of another partial web 22; 24 are brought.

Since the harp roller 41 and the register means 26 are fixedly connected to the carrier 43, neither their basic orientation to each other to readjust, nor requires two steps and / or two drives. In contrast to a over the entire width b17 a whole web 17 reaching harp roller 39 ( Fig. 5 ), the partial web width harp roller 41 has a significantly lower inertia, since it is shorter and thus also requires a smaller cross-section.

The indexing device 26 and the harp roller 41 having carrier 43 is associated with a turning device 44. This turning device 44 is similar to the exemplary embodiments according to an advantageous embodiment Fig. 3 to 5 arranged transversely to the running direction of the incoming part of the web 23 on a carrier 46 movable along a guide 46. The turning bars 28; 30 can be aligned in pairs again in parallel or orthogonal as required.

In an in Fig. 6 illustrated development, the superstructure 04 for a three-wide web 17 two such devices vertically offset from each other. Thus, one of the three partial webs 22; 23; 24 are guided straight, while for the other two partial webs 23; 24; 22 there is the possibility of turning and then registering. The second, vertically offset devices have in Fig. 6 the same reference numerals as first, but are marked with apostrophe.

To one of the partial webs 22; 23; 24 to lead in a vertically offset plane has one of the two carriers 47; 47 'to the associated turning device 44; 44 'upstream at least one, advantageously two substantially partial web width rollers 48, z. B.

Deflection rollers 48 on.

In Fig. 6 For example, all three partial webs 22, 23, 24 are guided one above the other, wherein the sub-web 22 guided straight, the middle sub-web 23 offset by the turning device 44 by a partial web width laterally under the first sub-web 22 and the third sub-web 24 first vertically through the rollers 48 and subsequently via the turning device 44 'laterally by two partial web widths under the first two partial webs 22; 23 is offset.

Fig. 7 shows a possible web run three partial webs 22; 23; 24, wherein the partial web 23 is turned by means of the turning device 44, the register means 26 and fed to the harp roller 41. The partial web 24 is first offset vertically via the rollers 48 before they are turned by means of the turning device 44 ', the register means 26' and fed to the harp roller 41 'is guided. The partial web 22 runs, for example, straight across the wide register roller 33 and the wide guide roller 34 on the wide or a portion 37 of the split harp roller 36. Instead of this web guide for the straight-running partial web 22 may also be a partial web width further harp roller, not shown, provided which the partial web 22 without interaction with the register and the guide roller 33; 34 is led directly.

The arrangement of the guide rollers 48 and the vertically offset arrangement of second devices for turning and registering a second partial web 22; 23; 24 from the embodiment according to Fig. 6 and 7 is the principle of the embodiment of the Fig. 3 to 5 transferred to. Correspondingly, then, in particular in the case of triple-width webs 17 (or printing units), a second carrier (27 '), not shown, with a turning device (07') and a register device (26 ') transverse to the running direction of the incoming part web 22; 23; 24 movably arranged on at least one further guide (08 ').

Accordingly, the "simple" version of the Fig. 3 to 5 , Especially with only double-wide webs 17 (or printing units), the embodiment according to Fig. 6 and 7 transferred to. In this case, only the apostrophized or non-apostrophised parts or devices are to be removed.

In a third embodiment ( Fig. 8 ) is in contrast to the first embodiment, a register device 51 is not directly and rigidly connected to a carrier 52 for the turning device 07, z. B. with a turning bar 28; 30 is connected, but is arranged on a separate carrier 53. Both carriers 52; 53 are arranged on at least one common guide 54 in a plane parallel to the plane of the incoming part of web 23 transversely to the direction of movement. As in the preceding exemplary embodiments, the parts of the register device 51 and the turning device 07 which cooperate with the corresponding sub-web 23 are dimensioned transversely to the running direction in their width such that their projection essentially corresponds to the width b23 of the incoming sub-web 23. Regarding the possible paths of straight running as well as fallen and possibly turned partial webs 22; 23; 24 is essentially based on the comments Fig. 5 directed. In contrast to Fig. 5 However, the fallen sub-web 23 is not before passing through the two turning bars 28; 30, but after circulating the first and before circulating the second turning bar 28 of the register means 51, respectively.

The register device 51 has, in an advantageous embodiment, only a single register roller 56, whose axis of rotation extends substantially perpendicular to the axis of rotation of the tension roller 18. The register roller 56 is arranged and dimensioned in cross-section, that between the register roller 56 and each turning bar 28 extending portions of the sub-web 23 form a plane.

The thus executed register device 51 does not require its own leadership and is sufficient usually not, or only slightly laterally out of the outer profile of the printing machine out. In addition, the paths of the turned partial web 23 are significantly reduced in comparison to register rolls which are arranged outside the lateral profile of the printing press, ie, for example, outside a side frame.

The fallen in this way and possibly turned sub-web 23 and straight-running sub-webs 22; 23; 24 or a second fallen and possibly turned sub-web 22; 23; 24, as in the embodiments according to Fig. 3 to 5 if necessary, wide register and deflection rollers 33; 34, wide or split harp rollers 39; 36, or too accordingly Fig. 6 shown partial width harp rollers 41 are continued. A device according to Fig. 8 with the two carriers 52; 53, the register 51 and the turning device 07 and the guides 54 may be executed as in the context of the second embodiment, in particular for three-wide printing presses, each entire web 17 two times vertically offset from each other. On the required device for displacement of the corresponding partial web 22; 23; 24 is referred to the aforementioned embodiment and then to be arranged on the carrier 52, but not shown rollers (48).

The guides 08; 42; 46; 54 of the aforementioned embodiments can be realized in many different ways. For example, as illustrated, each carrier 25; 27; 43; 47; 52; 53 by a plurality of identical or different guides 08; 42; 46; 54 be guided. For example, the guides 08; 42; 46; 54 as spindles 08; 42; 46; 54 be executed with at least sections threaded, which is rotatably mounted on both sides and a support 27; 43; 47; 52; 53 jointly associated spindles 08; 42; 46; 54 z. B. are rotatably driven by a common drive, not shown.

The carriers 27; 43; 47; 52; 53 can, however, in the manner of sliding blocks 27; 43; 47; 52; 53 also in rigid guides 08; 42; 46; 54, z. B. on profiles 08; 42; 46; 54, be guided.

In this case, a drive of the carrier 27; 43; 47; 52; 53 also take place via a drivable spindle or otherwise.

The storage of the turning bars 08 and the register roller 56 from Fig. 8 was shown flying, but can also be done on both sides. For this purpose, either further guides for receiving further support can be arranged, or the existing, multiple guides 08; 46; 54 will be split accordingly. However, the flying storage has advantages in terms of technical complexity and a smaller risk of tilting.

In an advantageous embodiment of a processing machine for web-shaped material, for. B. a web-fed rotary printing press, in particular for a superstructure 04, are all with a part-width web 22; 23; 24 cooperating, rotating, driven only by friction guide elements 41; 31; 32; 48 partial width or designed as a sectionally rotatable guide element 36. Ie. that depending on the equipment of the machine before the former 11; 12 last undriven, a layer associated with roller 36; 41, if present, a register roller 32 and optionally one or more guide rollers 31, 48 are made partially or in sections rotatable.

It can in the superstructure 04 of a partial web 22; 23; 24 even more in the figures, not shown guide elements, in particular in the part-width or sections rotatable design to be assigned. Preferably, all, one sub-web 22; 23; 24 or their web guide between longitudinal cutter 06 and former 11; 12 associated, in particular the non-driven rollers 31; 32; 36; 41; 48 part-width or sections rotatable and optionally existing turning bars 28; 30 partially executed.
