Description

The invention relates to a printing machine with a spreading device according to claim 1.

By the WO 2010/054910 A2 is a spreader in the web of a web press a continuous web known whose spreading effect is designed to be variable with respect to their effective width stretching strength.

The DE 10 2009 014 477 A1 relates to an adjusting device for a web guiding with a rotating frame through which an incoming material web can be laterally offset for their further course.

In the WO 2004/056686 A1 For example, in a device for processing and / or conveying a web, various web-processing tools are known which can be adapted to different web widths of the web to be processed.

From the WO 2004/014770 A1 a device for guiding a part widths web is known, wherein one or a group of such guide elements is movable transversely to the inlet direction of the part-width web or are.

The DE 38 39 473 A1 discloses a split spreader roll, the halves of which can be coupled independently of each of the other half in the freewheel or in a direction of rotation in the direction of web travel reversed direction driven shaft. As a result, the roller should be usable both as a spreader roller, and as a straightening roller.

The EP 0 683 123 A1 discloses a web guiding device of a web-fed printing machine with a device for correcting a lateral alignment or a possible inclination of a web by means of two rotating frames, which can be adjusted by respective actuators independently of one another in their position. In this case, a rotating frame supporting the rollers is pivotable both about its axis of rotation and in a direction transverse to the direction of web travel adjustable.

In the DE 35 07 084 A1 discloses a device for guiding and spreading a web, wherein a Ausstreifeinrichtung is arranged directly with two Ausstreifwalzen a correction roller in the conveying path of the web. In this case, the correction roller is formed in the outer peripheral region of slats, which can be designed to adapt a web width stretchable or divided and finger-like interlocking. The speed of the roller surfaces formed with oppositely divided threads is greater than the web speed, so that outwardly acting stripping forces can be generated in the web from the center.

By the DE 15 74 386 B a device for securing the lateral registration of webs is known, which comprises two parallel to each other and inclined to the path extending air-blown turner bars. The angle of inclination of the turning bars to the incoming web and thus the lateral offset is adjustable.

The DE 103 52 619 A1 discloses a method and a device for influencing the fan-out effect by a device by means of which a width "grown" due to moisture penetration can be achieved by means of a plurality of positioning means which are spaced apart from one another in the direction of the web and which can be designed as support elements or nozzles. Rail can be targeted narrowed.

In the DE 10 2005 048 246 A1 a compensation device is disclosed with two compensation structures which are movable relative to the other transversely to their Umschlingungsachse. In addition, a hollow cylindrical roller is disclosed as a guide device in the path, on the length of which raised and slightly recessed portions alternate.

The invention has for its object to provide a printing machine with a spreader.

The object is achieved by the features of claim 1.

The achievable with the present invention consist in particular in that simple means a wide sections for different web widths and web layers without the risk of unintentional misalignment and / or conversely, a targeted lateral displacement is possible.

Of particular advantage is an embodiment, wherein the device is adjustable from the control station and / or by a Voreinstellsystem. In a further development, the placement of the device is integrated into a control process for regulating a web-run-relevant variable.

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

In an advantageous development og exemplary embodiments and expansion stages is on the or the actuating means 27 ( 27 ) of the device 21 acting adjusting device 28 instead or additionally as a control device 28 formed, with a sensor 33 a trajectory rule is observed and the in the control device 28 implemented control processes a compliance of the control variable relevant setpoint specifications implemented by the output side to the relevant actuator 27 ( 27 ) of the device 21 acts. In an advantageous embodiment exemplified here, the sensor 33 as a sensor detecting the web edge and / or the lateral web position or at least monitoring 33 , z. B. as a web edge sensor 33 , executed. Passes through the sensor 33 monitored track 20 ; 02.1 ; 02.2 and / or their monitored web edge in an unintentional manner to one side, so by the control process, a counteracting the bleeding points of the device 21 or their means 22.1 ; 22.2 () 22.1 ; 22.2 ) on the or the corresponding actuating means 27 ( 27 ).

As an alternative to web edge control or in addition to this, on both sides such a sensor 33 be provided, which are the two edges of the relevant train 02 ; 02.1 ; 02.2 monitor, an actuating means 34 be provided by the actuation of the spreading effect is variable in their total level, and provided an evaluation and / or control process and / or be implemented, which obtains information on the actually existing on-site web width from the location of the edges and -. B. by comparison with information on the expected web width, ie, for example, the original web or obtained by longitudinal section Teilbbahn possibly taking into account process-related widening or Verschälerungen - conclusions about possibly existing wrinkles or wave formation in the web 02 ; 02.1 ; 02.2 allows and / or pulls and, if the result is correct, the wrinkles or waviness of the device 21 , in particular a placement of at least one actuating means 27 ( 27 ) of the or the lateral force initiating means 22.1 ; 22.2 ( 22.1 ; 22.2 ) and / or the actuating means 34 caused the variation of the strength of the spreading effect. The adjusting agent 34 can as a drive 34 be formed by which one on the frame 24 stored, the axis 26 or stub axle or shaft or end receiving support element 37 , z. B. in the manner of a lever 37 or sled 37 , is movable in one direction with radial component to the spreader element 23 to shift in a radial direction and thereby to vary the spreading effect.

The device 21 can, depending on the application, at one or at the same time at several points of a path of a guided or to be led by the printing press web 02 ; 02.1 ; 02.2 be provided. Thus, for example, in one embodiment, an advantageous arrangement of the device with respect to a wrinkle-free and / or page register-appropriate feeding 21 in the railway track between the train 02 providing aggregate 03 and the printing unit 01 intended. This can also be omitted if otherwise required rotary frame. In another embodiment, in addition to this or instead, an arrangement of the device 21 be provided in the web path between two or more pressure points, whereby z. B. a faulty Farbpasser can be corrected in the transverse direction and / or a wave formation is avoidable. In addition to one or more of said arrangements or alternatively, the arrangement of such a device 21 in the railway track between the printing unit 01 and an aggregate 07 be provided for longitudinal cutting of the multi-width original web 02, whereby they can be corrected if necessary with respect to the lateral position of their cutting line and / or errors in the cut due to wave formation can be minimized. In the case of a printing press suitable for heatset printing, in addition to one or more of the aforementioned applications or instead, such a device 21 in the railway track, especially in the railway track of a still uncut railway 02 , behind the dryer 09 be provided. This can be specially such a device 21 be incorporated into the railway or - as also in 1 indicated - in a cost-saving manner, one of the cooling rollers of the cooling device 11 in the above manner as a laterally movable wide plug 23 be formed, which z. B. in the above manner by a drive motor 27 is adjustable and possibly additionally includes cooling. Finally, in addition to one or more of the above-mentioned applications or instead, such a device may be in the pathway of a previously from an original web 02 longitudinally cut partial web 02.1 ; 02.2 be arranged, for example, this wrinkle-free on a downstream folding funnel 06 to lead and / or make a slight correction of the lateral position.
