The invention relates to a device with a control unit and with a printed band regulator, which has several adjustment units, of a printer according to claim 1.

In offset printing of wet coils, the fan-out effect means a widening of a band of print material, for example, a paper band, due to moisture absorption. The registration differences originated in this way between the printing positions (colors), located successively in the printing, have to be corrected to obtain a printed product with a good print quality, as well as to avoid a too large amount of maculature. The correction can be carried out when installed, for example, in a printer configured as an eight-cylinder tower, after the first two positions of printing, that is, generally after the lower printing unit, a band regulator printed that deforms the paper band widened by the fan-out effect and corrects the color position between sf.

From document EP0850761A2 a registration adjustment system is known to adapt the registration of a band of material, which discloses all the features of the preamble of claim 1, among others, a register correction wheel that deflects the band of material and a print width of the material band is used and that is installed in a mobile way in the path of the material band, a first drive unit that is connected to the registration correction wheel and a control unit and which activates the registration correction wheel to adapt the printing width of the web, and a first position monitoring unit that is connected to the registration correction wheel and the control unit and that monitors the position 25 of the printing wheel. registration correction, the control unit being preferably integrated in a central control system of the machine.

From US6,244,182B1 a printed belt regulator with several wheels that can be adjusted against a band of material is known, the adjustment of the respective wheels being made by motor.

From WO2005 / 007406A2 a method for influencing the fan-out effect is known. In order to influence the fan-out effect, the image of a sensor that detects the printed image in a reading width with at least a quarter of bandwidth is evaluated first and, in case of differences with respect to a specified nominal value, transmits a adjustment instruction to an adjustment element in order to influence the fan-out effect.

35

From document US5,553,542A a control system is known in a multi-color roll printer, which allows a width of a band of impression material to be adjusted orthogonally to its transport direction, the wheels being able to move, for example, the wheels against the band of printing material in an area that runs along the band of printing material, it being possible to vary a wheel adjustment path, 40 oriented towards the band of printing material, by means of a motor control .

From DE29718907U1 a device is known for correcting the fan-out effect in rotary reels, a pivoting angle of individual adjusting elements and counter-adjusting elements being able to be pivoted separately, which can be adjusted against the paper web, for example, from a checkpoint of the machine.

From DE29501373U1 a device is known, located, for example, in an eight-cylinder tower, for correcting the fan-out effect in coil rotors with an adjustment element that locally deflects the band of its plane, the adjustment element being operated by means of a regulation circuit containing a regulating device that is connected on the input side to a sensor of measured values to divert the band in the direction of its width and is connected on the output side to a drive device of the element of adjustment, several adjustment elements may be provided in the direction of the bandwidth, respectively configured as image adjustment wheels, a display device preferably displaying, among others, wheel adjustments, being present at a checkpoint Image adjustment The image adjustment wheels, freely rotatably mounted, can pivot into the plane of the web, for example, by electric motors. Pivot movement occurs depending on nominal values registered in the regulating device, for example, adjusted by the operator, at the checkpoint. The regulation device and the measured value sensor are part, for example, of a color registration regulation unit that reads registration marks on the band. Document DE29501373U1 indicates that on the

widening of the band, identified as a fan-out effect, influence, for example, the speed of the band, the distance between the printing positions, the properties of the paper, the amount of wetting agent, the width of the band or the tension from the band.

5 From document DE10226482A1 a measurement potentiometer for positioning adjustment elements in printers is known, a current nominal value of angular position is transmitted through a bi-directional serial interface from a machine control directly to a programmable evaluation device, a signal being sent of digital measurement of the measuring potentiometer, after passing through the evaluation device, by means of a bus converter to the serial interface and from here to the machine control.

From DE4327646A1 a rotary lithograph press with a plurality of printing sections with a wetting unit is known, the printing sections being arranged along the tread of the paper web, and with a plurality of devices for bandwidth adjustment that are located between two groups of printing sections, each adjustment device having a pressure force application device for applying a pressure force on a side surface of a paper web in order to deform the paper web and thus obtain a corrugated surface that reduces the width of the paper web; a pressure adjustment device for adjusting the pressure applied by the pressure force application device on the surface of the web; and a control device for controlling the pressure adjustment device in response to information about the paper web, for example, the material, the dimensions, the speed of the web or the like, and the printing information, for example , displacements produced in the printed drawing.

From WO2005 / 072967A2 a method is known for compensating a transverse elongation of a printing material, a deformation of the printing material being performed, which compensates for the fan-out effect, 25 for example, mechanically by means of wheels of an image regulator which are adjusted against the printing material preferably on both sides thereof, the deformation of the printing material being controlled with the aid of a control unit, which controls the image regulator, preferably continuously within certain limits, in particular being able to control remotely, for example, from a printer checkpoint.

30

The invention aims to show a device with a control unit and with a printed band regulator, which has several adjustment units, of a printer, which improves compensation of a transverse elongation of a printing material, caused by the fan out effect.

The objective is achieved according to the invention by means of the features of claim 1.

The advantages, obtained with the invention, lie in particular in that the registration differences between the printing positions (colors), successively located in the printing, can be reduced considerably rapidly, that is, in a short response time , also during an ongoing production of a printer, 40 it being possible to easily integrate the adjustment units, which must be activated for this purpose, in an automatic open control chain or in a closed regulation circuit of automatic operation. It also opens the possibility of individually adjusting a compensation curve, depending on the respective production and / or the place of printing, with high operating comfort, for example, at a printer checkpoint, and updating it in a way automatic also during the production of the printer, if necessary. It is also advantageous that the adjustment units have in each case a very compact configuration and guarantee high reliability operation as a result of their encapsulation, preferably protected against dust and moisture, despite the use of electromechanical components.

Examples of embodiment of the invention that are explained in detail below are represented in the drawings.

Figure 1 schematically shows an eight-cylinder tower of a reel printer with printing mechanism cylinders 02, in particular transfer cylinders 02, which are fitted on both sides against a band of printing material 01, for example, a web of paper 01, two transfer cylinders 20 being placed in pairs in pairs in each case. Four transfer cylinders 02 are arranged on each side of the paper strip 01 for the realization of a four color printing. Therefore, the paper strip 01 passes in its transport direction T, oriented from the bottom up, through four printing positions, in which one of the four printing inks of the four color printing is applied respectively on the paper strip 01. The first two printing positions in the direction of transport 25 T of the paper strip 01, that is, the lower printing positions, form in the eight-cylinder tower a lower printing unit, while, on the contrary, the following two printing positions, that is, the upper printing positions, form a superior printing unit. Between the lower printing unit and the upper printing unit a printed band regulator 03 is arranged with, for example, frame adjusting units 04 arranged side by side on each side of the paper band 01 to compensate for an elongation 30 A01 of the impression material 01 that is produced by the fan-out effect. For a better understanding, the flat iron cylinders that interact with the respective transfer cylinders 02, as usual in offset printing, or other components and / or units that normally integrate a printing unit have not been represented. The transfer cylinders 02 transfer in their respective axial direction several printed images, located side by side, to the paper web 01, for example, two to eight printed images. The 35-coil printer is used, for example, in newspaper printing. In the case of this application, the printed images, arranged side by side in the respective transfer cylinders 02, correspond to a page of a newspaper.

Figure 2 shows in a simplified representation how a width B01 of the paper web 01 increases 40 respectively in the value of the transverse elongation A01 in the four successive printing positions, preferably in the two edges oriented in the direction of transport T of the web of paper 01, when passing through the eight-cylinder tower shown in Figure 1 due in particular to moisture absorption, if the fan-out effect is not compensated. The transverse elongation A01 at both edges of the paper web 01 does not necessarily have to have the same value.

Figure 3 shows the printed band regulator 03 of Figure 1 in an assembly representation, the term "assembly" being used in the sense of the definitions specified in DIN6789. Two crossbars, which are arranged parallel to each other at a distance A06, for example, in the range of 50 mm to 150 mm, in particular 80 mm to 100 mm, and which can be arranged respectively in the axial direction of the 50 cylinders transfer 02 between the frame walls (not shown) of the printer and between which the paper strip 01 can be guided, in each case support several adjustment units 04, for example, four adjustment units arranged side by side , each adjustment unit 04 being configured as a controllable module 04 with an adjustment means 07 acting on the paper strip 01, the adjustment means 07 being configured, on the other hand, as a wheel 07 that can be swiveled and rotatably mounted freely. In each module 04, an actuator 13 that executes the engagement, caused by the adjustment means 07, is arranged respectively in the plane of the paper web 01, this actuator 13 producing in the example shown the deviation of the respective wheel 07 ( Figure 5), the width B01 of the paper strip 01 deforming due to the respective deviation of at least one of the wheels 07 and thus correcting a displacement of the color register originated between different printing positions. The wheels 07 are deflected into the plane of the paper web 01 to adjust the wheels

07 against the paper web 01 or out of this plane to separate the wheels 07 from the paper web 01, deforming the wheels 07, pivoted into the plane of the paper web 01 on both sides, the width B01 of the paper band 01 in the form of S. The actuator 13 converts a control instruction of a control unit 33 (figure 9) into a mechanical work, that is, a movement executed by the wheel 07 in question. The actuator 13 is configured as an electromechanical drive 13. Another configuration, not claimed, of the actuator 13 may be in the form of a valve 13 that influences a current, in particular the pressure of an air current directed towards the plane of the paper band 01, as a result of its opening or closing controlled by the control unit 33. In the case of a pneumatic paper band regulator 03, the pressure of the current directed towards the plane of the paper band 01, which is adjusted by the control unit 33, corresponds to the adjustment means 10 moved by the respective actuator 13 in the case of a mechanical paper band regulator 03. Therefore, the actuators 13 are respectively the adjustment elements in a chain of control, on which the control unit 33 influences, if the control unit 33 is notified of a signal related to the adjustment of the adjustment means 07, in a regulation circuit, on which the u control unit 33.

In each adjustment means 07, an intensity of its engagement in the plane of the paper band 01 and, therefore, a degree of deformation of the paper band 01 can be controlled and dosed by means of a control instruction sent by the unit control 33 to the actuator 13. Each wheel 05 has an adjustable adjustment path S07 preferably preferably continuously, for example, in the range of 10 to 50 mm, in particular 15 mm to 25 mm. The modules 04 are positioned, preferably immobilized, for example, by means of a flange 08 and a detachable joint, for example, a threaded joint, in the respective cross member 06, the respective cross member 06 being configured, for example, as a profiled bar, preferably hollow, with a cross section, for example, rectangular, with a song length of, for example, 20 mm to 50 mm, preferably 30 mm to 40 mm. The modules 04 are arranged in their respective crossbar 06 preferably in an equidistant manner, for example, in each case at a distance A04 of 200 mm to 400 mm, in particular 350 mm. Each cross member 06 has, for example, a free distance or length L06 in the range of 1,700 mm to 2,400 mm, in particular 1,900 mm to 2,000 mm. The modules 04 are preferably arranged displaceably along their respective crossbar 06 and can be freely positioned, that is, in any position, on their respective crossbar 06.

Figure 4 shows on an enlarged scale one of the modules 04 with a corresponding wheel 07 that can be deflected along the adjustment path S07. The adjustment path S07 of each individual wheel 07 of the printed belt regulator 03 (Figure 3) can be adjusted at a printer checkpoint, for example, from -25% to + 100%, and can be varied in this interval. In case of an adjustment of -25%, the respective wheel 07 is separated to the maximum of the plane of the paper band 01 and, therefore, it is possible to introduce the paper band 01 between the two separated crossbars 06. In case of adjustment from 0% there is a distance of, for example, 0.5 mm, between the respective wheel 07 and the paper web 01. The maximum entry depth of each individual wheel 07 in the plane of the paper web 01 is achieved in case of an adjustment of + 100%. This percentage adjustment and the actual adjustment of the adjustment path S07 can be assigned between sf in a linear or non-linear manner. Each wheel 07 has a diameter D07 in the range of, for example, 50 mm to 100 mm, in particular 60 mm to 80 mm. The flange 08 of the module 04 is connected, for example, to a mounting plate 09 of the module 04, surrounding by dragging the mounting plate 09 and the flange 08 the cross section of the crossbar 06, in which it is to be place this module 04, so that module 04 can be fixed in a way resistant to rotation in the cross-member 06. The mounting plate 09 supports on one side a housing 11, in which it is preferably arranged in a manner protected against dust and the humidity at least the drive 13 to adjust the wheel 07 of this module 04, and supports on its other side, for example, a lever 12 to accommodate here the wheel 07 in question, which is represented in Figure 5. A shaft 14, joined 45 with the drive 13, passes through the mounting plate 09. The lever 12, which supports the wheel 07, is fixedly connected with this shaft 14. A rotating movement of the shaft 14, connected with the drive 13, deflects the lever 12 and, therefore, the wheel 07 mounted rotatably He laughed freely on an axial pivot. The adjustment path S07 of the wheel 07 may be limited in its two deflection directions respectively by a mechanical stop which protrudes in each case from the mounting plate 09 and collides with the lever 12 which supports, for example, the wheel 07 , in case of an inadmissible rotating movement of the tree 14.

In the preferred embodiment, the actuator 13, arranged in the housing 11 of module 04, is configured as a drive 13 to adjust the wheel 07 of this module 04, for example, as a motor 13 driven by electricity, in particular as a motor step by step 13, preferably as a stepper motor with 55-pin poles 13, for example, as a two-phase stepper motor 13, whose winding is connected, for example, in a unipolar manner. A turning torque, exerted by such drive 13, in particular the stepper motor 13, is transmitted in a multiply manner to the shaft 14, which deflects the lever 12, for example, by means of a gear 16, in particular a planetary gear 16, also arranged in the same housing 11 of module 04. A gear ratio of gear 16 can be located, for example, in the range of 500: 1 to 100: 1, in particular

400: 1 to 300: 1. Therefore, the motor 13 adjusts the adjustment path S07 of the wheel 07 of the respective adjustment unit 04 as a result of a rotation of the shaft 14, driven by it, preferably by means of the gear 16 coupled to the motor. The adjustment path S07, which can be executed at most by the wheel 07, requires, for example, an angle of rotation 9 of the shaft 14 in the range of 30 ° to 60 °, in particular 40 ° to 45 ° (Figure 4 ), 5 executing gear 16, for example, in total between 1,000 and 2,500 steps, in particular 1,800 to 2,000 steps. A potentiometer, provided on or next to the housing 11 of module 04 and preferably connected to the driven shaft 14, serves to detect the angular rotation position of this shaft 14.

By means of a line connection 17, for example, separable (figures 3 and 5), the respective actuator 13 for adjusting the wheel 07 of this module 04 is supplied with at least electrical energy, for example, in combination with a constant tension. By means of this preferably multipolar line connection 17, the actuator 13 to adjust the wheel 07 of this module 04 is also controlled by the electronic control unit 33 (figure 9), so that a line connection 17, which allows bidirectional communication , it is preferably also configured as a data interface 17, whereby the actuator 13 of the respective module 04 joins a digital network 34 for data exchange. In the data interface 17 an electronic address is registered that identifies the actuator 13 in question at least with respect to the control unit 33. In addition, preferably through this data interface 17 a measurement value is reported on the angular position of rotation of the tree 14, provided by the potentiometer, to the control unit 33 which controls, for example, the drive 13, thus configuring a closed regulation circuit in relation to the control exerted by the control unit 33. A data stream, directed by the potentiometer through the control unit 33 towards the drive 13, it is integrated in particular in a regulation circuit that operates automatically. The passage of the physical line, belonging to the digital network 34, is carried out first preferably on or along the crossbar 06, which supports the module 04, and then towards the control unit 33 preferably arranged outside the control unit. Print. Several different groups are connected to the digital network 34 that exchange data with the control unit 33, at least all the actuators 13 of the printed band controller 03.

25

The control unit 33 may be integrated, for example, in the printer control station. An exchange of data between components arranged in module 04, for example, the drive 13 and / or the potentiometer, and the control unit 33 is preferably carried out through a line system 34 configured as a digital network 34, whereby be integrated this system of lmea 34 in a network to control the printer. In the preferred embodiment 30, the network 34, whereby the control unit 33 exchanges data between sf and at least the respective actuator 13 to be controlled of the printed band regulator 03, is a network for controlling groups arranged in the printer, by for example, an inking mechanism and / or a wetting mechanism, which participate in a printing process that is developed in the printer.

35 The respective adjustment path S07 of each of the wheels 07 of the printed band regulator 03, shown in Figure 3, can be adjusted individually and independently of the other wheels 07 of this printed band regulator 03 from the control unit 33, for example, from the printer checkpoint. For this purpose, each module 04, belonging to a printed band regulator 03, can be addressed separately from the checkpoint, that is, it can be selectively controlled from the checkpoint by means of a single individual address , assigned to the respective module 04. This means that the respective actuator 13 of the adjustment units 04 is assigned respectively an electronic address that identifies it in the digital network 34 and by which a particular actuator can be selected from the many connected actuators 13 to the digital network 34, as well as means that the adjustment path S07 of the mobile wheel 07, for example, generated by this selected actuator 13a, can be adjusted in each individual case e 45 independently of the other actuators 13 from the drive unit control 33 via data exchanged through digital network 34, at least one control instruction. The digital network 34, whereby the control unit 33 exchanges data between sf and at least the respective motor 13 to be controlled from the printed band controller 03, is configured, for example, as an Ethernet-based network 34. Figure 9 shows in a block diagram the control in a device presenting the mentioned control unit 33 and the printed band regulator 03 which 50 is described above and presents several adjustment units 04.

As shown in Figure 9, the control station has at least one display device 36, in which various program masks 18 can be displayed, as well as a handling unit 37 that allows manually entering values or selecting values displayed in at least one of the program masks 55 18. Figure 6 shows by way of example a program mask 18 that is displayed at the control post and in whose lower left area a particular printing tower of the print is shown schematically. printer, as well as that it can be selected by means of at least one connection surface 19. As shown in the upper left area of figure 6, in the selected print tower the printed band regulator 03 can then be selected, arranged between the lower and upper printing unit of this

printing tower, by means of at least one other connection surface 21, it being possible to adjust the adjustment path S07 of each individual wheel 07, for example, by means of slides 22 or by entering numerical values in the input fields 23, assigned to individual wheels 07. If all wheels 07 must be adjusted in the same way, it is possible to enter numerical values also in an input field 24 5 used for general adjustment. The entry in the input fields 23; 24 refers, for example, to percentage figures that are related to the adjustment path S07, located between -25% and + 100%, and which are displayed, for example, below by a corresponding positioning of the slides 22 in their respective adjustment zone and / or through a display of this numerical value.

10 Figure 7 shows in an alternative way to figure 6 another program mask 18, in which a numerical value, in particular a percentage figure, can be entered for the respective adjustment path S07 of the wheel 07 in question in fields of corresponding input 23 for each of the wheels 07 of a selected printed band regulator 03. In a field of entry 24 a numerical value can also be entered for a unified adjustment of all wheels 07 belonging to this printed band regulator 03. The example shown 15 shows a compensation value of 15%.

The program masks 18 of Figures 7 and 6 have in common that, on the one hand, an individual adjustment of several wheels 07, preferably of all wheels 07 belonging to a certain printed band regulator 03, and which, by On the other hand, it is also possible to apply to these individual settings a value of 20 common compensation that can be entered. This compensation value, valid for all wheels 07, uses all the individual settings in the same way, for example, it adds the 15% entered to all the individual settings.

It is known that the intensity of the fan-out effect depends, among others, on the production speed of the printer, that is, on the number of revolutions of its printing mechanism cylinders 02, in particular the transfer cylinders 02 (Figure 1 ). The intensity of the fan-out effect will also depend on the properties of the printing material 01, for example, a grammage of the paper used. Figure 8 shows a program mask 18 according to the invention, which can be visualized in the display device 36 at the checkpoint and containing at least one diagram 26 with a development of a compensation curve 27 registered on the number 30 of revolutions of the printing mechanism cylinders 02, indicating the compensation curve 27 respectively that compensation value, for example, percentage, which is applied to all the wheels 07 belonging to a certain printed band regulator 03 in relation to the number of revolutions of the printing mechanism cylinders 02. In a memory of the control unit 33, several compensation curves 27 are preferably stored, each of these compensation curves 27 being assigned to a property of the printing material 01 or the grammage of the paper used Each of these compensation curves 27 can be consulted in the program mask 18 by a corresponding selection. In the example shown in Figure 8, the compensation curve 27, shown in diagram 26, is valid for a paper with the weight of 45 g / m2. The development of each compensation curve 27 can be defined and is also really defined by several support points 28, subdividing, for example, uniformly, the support points 28 the range of 40 the production speed traveled by the printer from its stop until its maximum speed. The amount of support points 28 can be freely defined for each compensation curve 27, for example, by means of an entry of numerical values in an input field 31. For example, ten support points 28 can be provided which subdivide the interval of the production speed, which extends from the stop to the maximum speed of, for example, 45,000 revolutions of the cylinder per hour, in nine equal speed intervals. The compensation value, belonging to the respective values of the production speed, can be edited, for example, in a table 29 assigned to diagram 26, that is, here numerical values can be entered for the respective support points 28. A from the numerical values, introduced in table 29, for the respective support points 28, the graphic development of the compensation curve 27 in question is then generated by the control unit 33 in the diagram 26 with the help of a line that joins the support points 50 28. In another input field 32 the development, shown in diagram 26, of the respective compensation curve 27 can be varied. For example, the development of the respective compensation curve 27 can be raised or lower in total, the value can be entered, in which the development of the respective compensation curve 27, as an absolute value or as a relative value, must be varied.

55 From the development of one of the compensation curves 27, shown by way of example in diagram 26 of Figure 8, it is evident that it is advantageous in a starting area A of the printer, that is, from its stop, for example, up to about a fifth or a third of its maximum production speed, start the respective compensation curve 27 with a comparatively large inclination to allow it to then descend in a subsequent acceleration zone B to its maximum production speed, by example of

nonlinear or asymptotically, continuously against a lower limit value of, for example, 30%. The adjustment of the adjustment path S07 of each wheel 07 of a particular printed band regulator 03, which will depend on the production speed of the printer, is thus summarized in a compensation curve 27, the compensation curve 27 rising in the starting area A of the printer with a greater inclination than when descending again 5 with the opposite sign in the acceleration zone B, located next to the starting area A, up to its maximum production speed.

The adjusted compensation curves 27 can be stored in the memory of the control unit 33 in relation to the selected productions, for example, a paper type, and / or in relation to the selected printing towers, that is, a printing location, and can be retrieved from memory as a preset in the program mask 18. After the entry or selection of a particular production in the program mask 18, the control unit 33 proposes for the respective printing places , that is to say, for the respective printing towers of the printer, presets determined for the adjustment path S07 of the respective wheels 07 of the printed band regulator 03, acting at the printing location in question, and / or adjusting these values specified automatically or by the printer operator after a release. From the respective presets, defined by means of the compensation curves, the adjustment path S07 of each wheel 07 of a particular printed band regulator 03 can be automatically updated during a running production of the printer, for example, by a regulation circuit administered by the control unit 33 or by a new manual entry into the control unit 33.
