Description

The invention relates to a device for processing and / or conveying a web in a web-fed rotary printing press according to the preamble of claim 1.

From the EP 12 38 935 A2 a device for longitudinal cutting of films and tapes is known, wherein an upper blade for setting a cutting width can be positioned transversely to the transport direction of the web.

By the DE 101 50 810 A1 a reel changer is known, wherein two roller arms for receiving a roll form a pair and each individually by a separate motor along an axis of rotation of the roller are movable.

The DE 196 02 248 A1 discloses a former, which is movable for lateral correction of the folded strand along an inlet gap of two subordinate rolls.

By the WO 01/70608 A1 is a positionable transversely to the direction of entry of the web turning bar and a positionable longitudinally to the inlet clearing of the web register roller known. The turning bar is pivotable in such a way that it deflects the track to the right or left depending on the position.

The DE 36 14 981 C2 discloses two web edge sensors, each having a drive and are controlled by a common control device. The similar discloses the DE 35 33 274 C3 ,

In the DE 195 40 164 C1 a transport direction is shown with two juxtaposed conveyors for continuous material, each device having an axially movable feed device.

A device with which it is possible to cut from a running paper web of maximum width two partial webs or three partial webs of variable width and to fold these partial webs is known from DE 42 04 254 A1 known. The device shown there comprises three formers, which are arranged in two planes, wherein two in a first plane adjacent formers are arranged transversely to the direction of the web to move either to fold both partial webs of a two-part paper web or for folding the two outer sub-webs of a tripartite Train to serve. An adaptation of other web-guiding facilities as the former to the respective web width is not provided.

From the DE 43 11 437 A1 a turner bar assembly is known, the turning bars are foldable to move a path turned to them by their width depending on the position of the turning bars to the left or to the right. This turner bar assembly is made with the device DE 42 04 254 A1 not readily combinable, since one with her, for example, offset by half a web width third sub-web does not hit the intended for her former.

The DE 100 03 025 C1 discloses an apparatus for processing a web having at least one former and a blade upstream thereof as a knife, wherein the knife and the former are movable transversely to the direction of the web by a common actuator.

The EP 0 457 304 A1 relates to a mechanism with two oppositely movable by a common drive machining elements of a device for folding bags.

The post-published EP 1 415 944 A discloses a device for conveying a web in a web-fed rotary printing press with a longitudinal cutting device and with a roller which is rotatably mounted in a frame and looped during operation of a web, wherein a plurality of, each a rotatably mounted roller bearing sliding blocks are slidably mounted on a guide rail and engage with a threaded spindle, the rollers press against the roller and roll against it. The threaded spindle has several sections which differ in terms of their sense of rotation and / or pitch. An electric motor acts on the threaded spindle.

The invention has for its object to provide a device for processing and / or promotion of a web in a web-fed rotary printing press.

This object is achieved by the features of claim 1.

On the one hand, a significant advantage is that there is no need for lengthy adjustments at the start of production. In contrast to settings, which only takes place during the pressure recording by means of control loops, the amount of waste can be significantly reduced.

A particular advantage of the invention is that it allows rapid adaptation to a change in the web widths to be processed, since a user does not have to individually access each individual web processing tool to be moved in adaptation to the web width.

A further saving of time results if the control unit itself is set up to automatically calculate and set the necessarily correlated positions of the different machining tools from a small number of input parameters. In the simplest case, it is sufficient to calculate these positions to specify only the width of a web to be processed; From this specification, the control unit can determine the required positions of all the processing tools in a simple manner on the condition that a reference line of all webs to be processed, eg. B. a right or left edge or preferably the center line, regardless of their width in the device assumes the same position.

Since the displacements of some web-processing tools required for adaptation to a changed web width are firmly correlated, the device can be simplified by using an actuator for displacing several web-processing tools simultaneously.

The web-processing tools of the device according to the invention include, for example, at least one former. With a suitable choice of the reference line, it may be sufficient if only one of two formers is displaceable; However, if you choose, which is preferred, the center line of the web to be processed as a reference line, so at least both of two juxtaposed folders must be displaced.

In order to produce a plurality of partial webs from a single initial web in the device according to the invention, which can then be fed to individual formers, the device according to the invention expediently has at least one knife for longitudinal cutting of the original web into part webs. If more than one such knife is present, at least one of them must be movable.

The device may further comprise at least one interval cutting knife for side-by-side longitudinal cutting of the material web. If the material web is a printed paper web, in particular a newspaper, such an interval cutting knife can be used to cut the web in each case locally at the level of every other page, in order, for. B. to produce a broadsheet signature with tabloid insert.

It is also advantageous if the device has a longitudinal cutting device with at least one knife, which is also preset transversely to the running direction of the web to set the cutting line for the partial webs to be generated.

If a starting web which has been cut into several partial webs is processed in the apparatus, then tension or catching rollers as web-processing tools are expediently assigned to each of the partial webs in the same way. It is therefore desirable that such rollers are also automatically positioned by the control unit according to the width of the output web to be processed and the number of partial webs.

Turning bars can also be provided as machining tools that can be displaced by the control unit. As editing tools here and in the following also Bahnleit-, Bahnantriebs- and / or web guide elements, such. As turner bars, pressure rollers and / or guide rollers understood.

To drive the displacement of the machining tools, the actuators preferably each comprise a threaded spindle, and the displaceable machining tools each have a sliding block, which is engaged with such a threaded spindle.

Advantageously, such a threaded spindle may have a plurality of sections which differ in terms of rotation and / or pitch, and the sliding blocks of a plurality of machining tools of the same type are respectively engaged with the different sections of a same spindle, coupled to the machining tools, but possibly in different directions and / or to shift speeds.

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

Fig. 1 a shows a former arrangement in which two paper webs 01, 02 side by side on a roller 03 and then in two formers 06, 07 are performed. The formers 04, 07 are mounted in a frame 04 parallel to the axis of the roller 03 slidably. An actuator for moving the former 06, 07 is formed by a parallel to the axis of the roller 03 threaded spindle 08, which has two sections with opposite equal slope, and a drive 11, for. B. electric motor 11, for Drehantreiben the threaded spindle 08. The drive 11 and the former 06; 07 moving gear can also be carried out in other ways. The formers 06, 07 are each provided with a sliding block 09, wherein the two sliding blocks 09 are engaged with different sections of the threaded spindle 08, so that a rotation of the threaded spindle 08 drives the formers 06, 07 to opposite movements. An electronic control unit 10 or a presetting system S below controls the electric motor 11 on the basis of a width of the paper webs 01, 02 entered by the user on the control unit 10 (or of the system S). The information about the width can be sent to the control device 10 (FIG. or system S) in other ways, for. B. by reading a common value or in a product planning system, a machine control, imposition and / or a control center (in Fig. 9 equivalent to P).

A connected to the left former 06 frame 15 or frame 15 also serves as a support for a bearing of the roller 03, so that the roller 03 follows each movement of the former 06. The right side of the roller 03 is telescopic on a stand fixed to the frame 04, z. B. via an axially displaceable bearing 25 ( Fig. 1 b) , movable. With the folding hopper 06 thus moves the roller 03 and z. B. a circumferential groove 20 on the roller 20 (dashed in FIG Fig. 1 b) , which cooperates with a knife for the continuous or discontinuous longitudinal section as a cutting groove.

Also rigid with the former 06, z. B. on the frame 15, an interval cutting knife 05 or Skip Slitter 05, which is mounted above the roller 03 is connected. The interval cutter 05 has a rotating interrupted blade which is aligned with the fold line of the former 06 and alternately alternately cuts one pair and leaves the other uncut from pairs of pages printed alternately on the paper web 01. If the uncut page pairs are broadsheet pages with lines oriented transversely to the direction of conveyance and the cut pages are tabloid pages whose lines are oriented in the conveying direction, the paper web 01 in a connected folding apparatus, not shown, can be turned into a simple one Make a signature with a deposit in half the page size.

In Fig. 1 b is the setting of the former 06, 07 for the processing of two paper webs 12, 13 shown opposite the paper webs 01, 02 of the Fig. 1 a are narrower by a value d. The center line M, at which the webs 12, 13 touch, has the same position with respect to the frame as the center line M between the webs 01, 02 in FIG Fig. 1a , To adjust the former 06, 07 for the processing of such narrow paper webs 12, 13, the threaded spindle 08 is rotated via the electric motor 11, so that the former 06, 07 are each shifted by d / 2 to the center line M.

In an advantageous modification or development is with the former 06; 07 - in addition to or instead of the connection to the knife 05 - one of the funnel tip downstream driven pulley 30 together or simultaneously with the former 06; 07 laterally movable. For this purpose, the former 06; 07 preferably connected via a common frame 15 with a bearing of the roller 30. When moving the former 06, 07, the roller 30 is moved simultaneously. The roller 30 is designed either as a driven transfer roller 30, via which a the former 06; 07 leaving strand is guided and undergoes a change in direction. In another embodiment, the roller 30 as z. B. driven single-motor train roller 30 a Zugwalzengruppe against which a pressure roller 35 is adjustable. In this case, the entire train group 30, 35 with the former 06; 07 connected.

Of course, could be a former arrangement of in Fig. 1a . 1 b also have three or more formers for processing a corresponding number of partial webs shown type. If three parallel partial webs are to be processed and their center line M always has the same position with respect to the frame, irrespective of the width of the webs, the two outer formers are to be displaced by d each time the width of the sub-webs changes by d the middle former remains unmoved. In the case of four partial webs, the displacement d / 2 is accordingly the same for the two middle and 3d / 2 for the two outer, etc.

In an advantageous embodiment, it is for presetting the printing press (see Fig. 9 ) provided that the controller 10 and the drive 11 for the described movement of the former 06; 07 is in signal communication with the system S. Based on the production data (eg the web or partial web width b; b '), the current position of the former is 06; 07 compared with a predetermined or predetermined for this production situation and possibly causes a corresponding movement via control commands to the relevant drive 11. Depending on the web or sub-web width and / or location whose center is the former 06; 07 (or the funnel tip) to be positioned laterally. The former 06; 07 is z. B. Positioned such that the partial web 02; 05 in the center with respect to the funnel tip on the relevant former 06; 07 runs up. Preset values can be tabulated for the various productions, or a calculation can be found in the system on the basis of the web widths and the lateral offset resulting web paths.

Fig. 2a shows a Fangrollenanordnung as an example of web processing tools of a device according to the invention. This catch roller assembly consists of a roller 14, which is wrapped in operation by a catching, not shown in the figure paper web, a plurality of rollers 16, a plurality of sliding blocks 18, 19, 21, a guide rail 17, a threaded spindle 22 and one of the already mentioned Control unit 10 (or system S) controlled electric motor 23rd

The roller 14 is rotatably mounted in the frame 04. Parallel to the roller 14, the guide rail 17 is mounted in the frame 04. On the guide rail 17 a plurality of sliding blocks 18, 19 are arranged displaceably. A centrally arranged to the roller 14 sliding block 21 is fixedly arranged on the guide rail 17. The sliding blocks 18, 19 and 21 each carry a rotatably mounted roller 16. The rollers 16 press against the roller 14 and roll against them. Since the rollers 16 are designed to be rotatable only in one direction, they prevent a running back of the wound around the roller 14 paper web in case of a paper web breakage.

The threaded spindle 22 pierces the frame 04 on one side and projects out of the frame 04 at this point. It is aligned parallel to the roller 14 and the guide rail 17. The threaded spindle 22 has two different threaded portions with different directions of rotation, which are separated by a non-threaded portion. On this non-threaded portion of the sliding block 21 is arranged. The two threaded portions have slopes which increase along a longitudinal axis of the threaded spindle 22 in proportion to the distance from the sliding block 21. The sliding blocks 18, 19 are with the viewed from the sliding block 21 from left or right threaded portion not about an internal thread with several turns in engagement - such would be stuck due to the variability of the slope, but a single narrow pin on a small peripheral portion of the threaded spindle 22 engages the thread thereof At the protruding from the frame 04 end portion of the threaded spindle 22 of the electric motor 23 engages the threaded spindle 22 at.

If the catching roller arrangement shown is to be used for a paper web with a narrower width, the sliding blocks 18, 19 are displaced along the guide rail 17, as in FIG Fig. 2b shown. In this case, the threaded spindle 22 is rotated via the drive 23. Due to the different rotational direction of the two with the sliding blocks 18 and 19 engaged threaded portions move in a rotation of the threaded spindle 22, the sliding blocks 18 from the left and the sliding blocks 19 from the right to the central sliding block 21. The movement of the sliding blocks 18, 19 takes place synchronously, however, as a result of changing along the longitudinal axis of the threaded spindle 22 gradients of the threaded portions are the paths that the sliding blocks 18, 19 and thus run them guided rollers 16, proportional to their distance from Depending on the width of the paper web to be processed, the sliding blocks 18, 19 via a corresponding rotation of the threaded spindle 22 can be moved more or less close to the sliding block 21 steplessly, and thus set the catch roller for any paper web widths. The sliding blocks 18, 19 can be arbitrarily placed on the spindle 22 before a displacement; the ratio of their distances is maintained at a shift.

It would also be conceivable to provide two threaded sections, each with a constant pitch over its length. This is sufficient for a roller assembly with no more than three sliding rollers 16. In the case of a larger number of rollers, as in Fig. 2b As shown, the distance between the two left sliding blocks 18 (and also between the right sliding blocks 19) would remain constant with a displacement and pitch ratios would change with a displacement.

Another possibility would be to provide each of the four sliding blocks 18, 19 a separate threaded section with a specific pitch. The variability of the web widths to which the catching roller arrangement is adjustable, however, then limited by the fact that the sliding blocks - at least those which are coupled via an internal thread with multiple turns to the spindle - the threaded sections with the appropriate pitch for their thread can not leave .

It could also be several threaded spindles, each with two sections of opposite equal slope are provided, each carrying sliding blocks of each other with respect to the center line M mirror-opposing roles. These threaded spindles are expediently identical to one another. In order to achieve different displacements of the rollers coupled to them, the threaded spindles can be driven by a common electric motor via a gearbox with each adapted gear ratio, or each threaded spindle has its own electric motor, which is controlled by the control unit individually according to the required displacement.

In the manner just described, train roll arrangements for paper webs to be processed with different widths can also be made adjustable, since pull roll arrangements in principle have an arrangement analogous to catching roll arrangements. Such presetting values are tabulated for the various productions, or else a calculation takes place in the system S using the width and the lateral offset to be obtained.

Fig. 3a shows a longitudinal cutting device 71 of a superstructure 67 (FIG. Fig. 9 ). The slitting device 71 is designed to longitudinally cut an incoming web into a plurality of partial webs, for example two partial webs. In this case, two guide rails 24 are arranged parallel in the frame 04. A paper web 26 is guided between the two guide rails 24. Two carriages 27 are slidably held on the two guide rails 24. They are mirror images of each other executed and mounted. Each carriage 27 carries a rotating knife 28 with perpendicular to the paper web 26 aligned cutting edge and cooperating with the knife 28 counter-pressure roller 29 (counter knife). Between the carriage 27 is another knife 32, which is also perpendicular to the paper web 26, and cooperating with this counter-pressure roller 31. The paper web 26 is cut by the knives 28, 32 and counter-pressure rollers 29, 31 in four partial webs. A parallel to the guide rails 24 threaded spindle 33 has two threaded portions with different directions of rotation and the same pitch, each of which is in engagement with one of the carriage 27. An end portion of the threaded spindle 33 projects out of the frame 04 on one side. At this end portion is a drive 34, z. B. electric motor 34, for rotational driving of the threaded spindle 33 is provided. The individual knives 28; 32 or counter knife can also be driven together by a different kind of drive 34 or by individual drives per knife or knife pair.

If the longitudinal cutting device described is intended to cut a paper web 36 of narrow width into four partial webs, then as in FIG Fig. 3b shown the threaded spindle 33 is rotated by the electric motor 34. Since the carriages 27 engage on different threaded portions of the threaded spindle 33 with different directions of rotation and the same pitch, the rotation of the threaded spindle 33 causes the carriages 27 to move one another at equal distances on the central knife 32. The rotation of the threaded spindle 33 is continued until the distance between two blades 28, 32 corresponds to a quarter of the width of the narrow paper web 36.

The operation of the motor 34 is controlled by the control unit 10 (or system S) ( Fig. 1 a) controlled or predetermined, which calculates the positions of the blades 28 based on a set by the user or automatically detected by (not shown) sensors width of the web to be cut or the resulting partial webs from the cutting.

In the case of several blade units (pairs of blades 28, 32 and counter blade 29), e.g. all individually driven and / or individually on / off.

The axial positioning or at least presetting of the machine control is preferably carried out automatically on the basis of the width of the web intended for printing and the product-specific cutting lines or from a control console. For this purpose, for example, before the start of production by the system S (by the machine control or a corresponding software program), the current setting checked for preset production required for the planned production and / or a default setting by acting on the drive 34 (or the drives 34). Such default values can be stored in tabular form for the various productions, or else a calculation takes place in the system S using the lateral offset to be obtained by the web widths and.

In Fig. 4a For example, a turntable with two crossed turner bars 37, 38 is shown as another example of web processing tools that may be included in the apparatus. Two pairs of guide rails 39, 41, referred to as front 41 and rear guide rails 39, are held between plates of the frame 04. Of each pair of guide rails 39, 41, only one upper guide rail is visible in the figure, as it conceals the rail underlying it. At the ends of the turning bar 37 is a respective sliding block 42, 43 is provided, wherein the sliding block 42 is slidably mounted on the visible upper guide rail 39 of the rear guide rail pair and the sliding block 43 on the visible upper guide rail 41 of the front guide rail pair. Accordingly, two sliding blocks 44, 46 are provided at the ends of the turning bar 38, wherein the sliding block 44 is slidably disposed on the non-visible lower guide rail 39 of the rear guide rail pair and the sliding block 46 on the non-visible lower guide rail 41 of the front guide rail pair.

Between the guide rail pairs 39 and 41 and transversely to these in the frame 04, a guide roller 47 is rotatably arranged.

A perpendicular to the guide rail pairs 39 and 41 incoming paper web 51 rotates the oblique turning bar 37 and thereby changes their direction by 90 °. It wraps around the guide roller 47 and runs back from this and the obliquely placed, with the turning bar 37 crossed turning bar 38, whereby their direction again changes by 90 °, so that it has acquired its original direction back after leaving the turning table, however is offset by exactly one paper web width and is turned.

A to the guide rails 39, 41 parallel pair of threaded spindles 48, of which in the figure, a lower threaded spindle 48 is covered by the upper threaded spindle 48 are rotatably supported in the frame 04. At one end portion of each spindle 48 engages a drive 49, e.g. an electric motor 49 on.

If the described arrangement as in Fig. 4b shown used for a paper web 52 with a smaller width, so on the one hand, the distance of the turning bars 37 and 38 must be changed so that an offset of exactly one web width is achieved. Therefor controls the control unit 10 (or system S) (not shown in the figure) an opposing movement of the motors 49 and thus the turning bars 37, 38. On the other hand, in particular if more than two partial webs are to be processed, a same-directional displacement Turning bars 37, 38 may be required to ensure that the partial webs do not come too close to the ends of the turning bars 37, 38. For this purpose, the control unit 10 (or system S) controls the motors 49 in each case in the same direction.

The just described turning table is in Fig. 5a shown after a conversion. The turning bars 37 and 38 are arranged in this embodiment parallel to each other with the sliding blocks 42, 43, 44, 46 on the guide rails of the guide rail pairs 39 and 41 slidably.

A paper web 53 to be offset runs perpendicularly to the pairs of guide rails 39 and 41 in the turning corner, wraps around the turning bar 37 and the turning bar 38 in succession, and leaves the turning table laterally displaced by one width of paper web without being turned.

As in the case of Fig. 4a . 4b moves to adapt the turning table to a paper web 54 (FIG. Fig. 5b ), which has a smaller width than the web 53, the control unit 10 (or system S) on the one hand the turning bars 37, 38 toward each other, so that the distance of the turning bars is adapted to the changed web width, and shifts both, if necessary Turning rods 37, 38 in the same direction, so that the web 54 hits sufficiently centrally on the turning bars.

Fig. 6 shows an advantageous embodiment of the turning bar assembly according to Fig. 4 However, the arrangement only one carrier 39; 41 for the two turning bars 37, 38 has. The sliding blocks 43; 46 slide on the same support 39; 41 and are driven by a common threaded spindle 48, which has two opposing threads for each one of the sliding blocks. The spindle is driven by the motor 49, wherein upon rotation of the threaded spindle, the sliding blocks 43; 46 move in opposite directions.

Fig. 7 also shows an advantageous embodiment of the arrangement Fig. 5 , here as in Fig. 6 a common threaded spindle 48 with opposite threads for the sliding blocks 43; 46 is provided. The sliding blocks 43; 46 also run on the same support 41. Driving the threaded spindle 48 by the common motor 49 causes an opposite movement of the two turning bars 37; 38 with their sliding blocks 43; 46th

A turning plant 72 of a printing machine ( Fig. 9 ) has at least one turning table with two associated turning bars 37; 38, by means of which a partial web 51 to 54 brought to another flight and / or can be overthrown. It includes a pair of turning bars 37; 38. In an advantageous embodiment not shown here are two turning decks, ie two pairs of turning bars 37; 38 for offset or to fall two partial webs 51 to 54 provided. The turning bars 37; 38 of a pair can be arranged as shown either parallel to each other and inclined at 45 ° to the incoming web (offset), or they are perpendicular to each other and inclined at 45 ° or 135 ° to the incoming web (falls and possibly offset ).

In an advantageous embodiment, all turning bars 37; 38 in the plane of each incoming web by 90 ° swivel or tilted executed. In a variant to the FIGS. 4 and 5 is also a flying storage of the turning bars 37; 38, ie advantageous with a fixed and a free end. In this case, eliminates the carrier 39. In development is the turning bars 37; 38 each associated with an unillustrated means which the current position of the turning bar 37; 38 - tilted to the left or to the right - detected and reported to the machine control or the control station of the machine or the system S. These may be, for example, initiators which are activated or deactivated mechanically (switch) or electromagnetically (induction, light barrier) as soon as the turning bar 37; 38 located in one of the intended positions. The printer or a program can then check whether the turning bars 37; 38 in the position required for the planned production.

It can be output by the system S an error signal when the position of the turning bar 37; 38 to the intended production (or web run) does not match.

Each turning bar 37; 38 is arranged as shown above in a preferred embodiment total in a direction transverse to the incoming web movable in the superstructure 67. Hereby, the turning bar 37; 38 adapted to a product or a web run or web width by means of the drive 49 positionable.

For presetting the printing machine, it is advantageously provided that the drives 49 of the turning bars 37; 38 are in signal communication with the system S. Based on the production data (eg intended web guide, resulting theoretical cut line, and / or web or web width), the current position of the turning bar 37; 38 compared with a predetermined or predetermined for this production situation and possibly causes a corresponding movement via control commands to the respective drives 49. Such default values can be stored in tabular form for the various productions, or else a calculation takes place in the system S using the lateral offset to be obtained by the web widths and.
