Definitions
- the invention relates to an apparatus and a method for Setup control of a printing press and for web control according to the preamble of claim 1 or 13.
- Web-fed rotary printing presses are known, the devices to detect a register error between the for different colors of printing units arranged one after the other Correction of register errors, a so-called register regulation, exhibit.
- These devices are usually based on a detection of each pressure level on a separate Edge section of a material web also printed Registration marks by means of an optical sensor. By Detection of an actual distance between individual registration marks and comparison with a predetermined target distance can be Register errors between subsequent pressure levels permanent compensate.
- a specially coded brand can be printed, for example in the form of a so-called barcode, however can only be poorly evaluated using an area scan camera can, but usually a one-dimensional optical Sensor, a so-called path switch, is required. So by means of the entire circumference of the cylinder was scanned and then electronically with appropriate algorithms and pattern recognition process the brand measurement pattern as well whose exact position can be determined.
- a disadvantage the need for this next to the area scan camera additionally provide a one-dimensional optical sensor because the area camera at the first cylinder revolution is unable to correctly capture the brand field and then the correct position of the impression cylinder at the first cylinder revolution at the appropriate speed align.
- the invention is therefore based on the task of a simple one Device or a simplified method for Control to create an area camera, so that in addition to the existing sensors no further sensors required are.
- the device according to the invention enables by means of a only each printing cylinder of a web-fed rotary printing press assigned optical sensor both a quick set-up control after changing roles as also effective register regulation.
- a block mark for example in the form of several different wide contrasting rectangles, or in the form of a Rectangular bar and several subsequent points, by means of a line scan mode is scanned.
- the camera simulates Do a barcode reader by using one or less side-by-side camera lines, which in turn only a few pixels from the center are used, a one-dimensional Scanning is simulated. That way only one optical sensor in each printing cylinder Form of a camera necessary, its different mode of operation using software and hardware technology in the downstream evaluation unit can be realized.
- such one-dimensional optical sensor In the set-up phase of the printing press, such one-dimensional optical sensor a full cylinder circumference of a printing cylinder and scanned in the downstream evaluation unit, together with the output signal a rotation angle sensor assigned to the pressure cylinder, processed.
- you can use a camera editing window all brands recorded and measured become.
- an area scan camera it cannot be without also searched an entire cylinder circumference for brands and then analyze them. Rather, the successive ones should Recording window after a sequence be evaluated. For example, has a capture window a length of 50 mm in the running direction, are for examination a format of 500 mm in length to the presence brands require at least ten machine revolutions. This inevitably leads to increased waste in the printing press.
- the entire scanner can be scanned within one cylinder revolution Scan the cylinder circumference and use the appropriate methods the pattern recognition for the presence of an AME block mark investigate.
- the positioning of the printing cylinder can be set in this way be that the register mark field directly below the Camera lens is because the distance from the block mark to Register mark field is a stored in the evaluation unit Size.
- the setup phase the printing machine ended and the printing phase can be done manually or be started automatically.
- one second operating mode of the digital camera switched wherein this is a complete output of their entire pixel matrix delivers to the evaluation unit. In this operating mode then the actual measurement of the individual register marks performed; the register control is then activated.
- An advantageous improvement in the scanning quality can be achieved by achieve additional lighting for each camera section.
- Fig. 1 shows a schematic representation of a section a web of material to be printed shown in FIG. 3 3, for example a sheet of paper printed in a printing machine, not shown here, printed in multiple colors becomes.
- One is indicated by means of a perforation 10 edge strip 4 connected to the material web 3, on the markings 1, 2 for quick setup of the printing cylinder as well as for register regulation, that is to say for compensation regulation of register errors.
- the edge strip 4 is after the printing process from the material web 3 or separated from the printed sheet.
- a so-called AME block mark 1 consisting of several rectangles of different widths 1a, 1b, 1c, the during the first printing pass of the first printing cylinder on the Edge strip 4 is also printed.
- This block mark 1 is in Type of a so-called barcode designed and used for quick and waste-free setup of the following, intended for printing different colors, Pressure cylinder. So in the setup phase of the machine by means of a one-dimensional optical sensor, the Function and mode of operation described in more detail below will be a full cylinder circumference each Printing cylinder are scanned, the resulting signal in an evaluation unit downstream of the optical sensor processed and to control the respective printing cylinder, each of which is also equipped with a rotation angle sensor is used.
- a so-called register mark field can also be seen in FIG. 1 2, which is in the direction of travel of the material web 3 is in line with the block mark 1, so that the optical sensor with a fixed adjustment of both the block mark 1 as well as register mark field 2.
- the Register mark field 2 consisting of several marks 2a, 2b, 2c, 2d, is in a certain, firmly defined and as Brand offset b designated distance from the block mark 1 applied.
- Brand offset b designated distance from the block mark 1 applied.
- Those of the one after the other and for the Printing cylinders provided in different colors successively printed individual marks 2a, 2b, 2c, 2d of register mark field 2 are as long as there is no register error occurs, equally spaced.
- This distance is in hereinafter referred to as brand distance a.
- the brand distance a is in permanent operation with the printing press optical sensors detects, evaluates and thus serves for regulation of register errors.
- Fig. 2 shows a variant of the brand field consisting of an AME block mark 1 and a register mark field 2.
- Die rectangular mark 1a and the punctiform marks 1b and 1c of the block mark field 1 are for adjusting the printing cylinders intended; they are therefore also referred to as the base color.
- the punctiform marks 2a, 2b, 2c and 2d of the register mark field 2 preferably have the same dimensions on like the marks 1b and 1c of the block mark field 1.
- the brand 2d in turn represents a trademark, the marks 2a to 2c the colors of the other printing units.
- Camera 14 for example a CCD digital camera, according to the invention in two different operating modes can be used.
- a so-called search mode hereinafter referred to as the first operating mode (mode I)
- the camera 14 becomes comparable as a one-dimensional sensor a barcode reader, and is therefore able to Find block mark 1 quickly and its exact position to determine.
- operating mode I will only a small area of the camera image is evaluated, for example, only one or two lines in the middle of one the pixel matrix representing the camera image. Of these Lines are evaluated only a few pixels, so that a one-dimensional sensor is simulated with the camera 14.
- the block mark is 1 from each of the individual printing cylinders assigned camera 14 is found, the correct angle Positioning of the printing cylinder using the rotation angle sensor set so that the register mark field 2 is located exactly under the lens of the camera 14.
- This automatic Positioning is no problem over the previous one and the value of the brand offset stored in the evaluation unit b adjustable.
- the printing cylinders can be used with it at the same time with minimal waste in the shortest possible time set up.
- the regulation of the pressure cylinder to compensate for register errors is then carried out during operation of the printing press Using a second operating mode (mode II) of the camera 14.
- mode II a second operating mode of the camera 14.
- the camera 14 is operated as a conventional area camera, the detected pixel patterns, particularly with regard to the mark distances, in the downstream evaluation unit be compared with stored target patterns and depending on the agreement or deviation, a register regulation can be done.
- FIG. 3 shows a schematically simplified illustration a section of the material web 3 or Sheet with printed register mark field 2 and above arranged camera 14.
- a regular can be seen spaced perforation 6 close to an outer edge 8 of the web Edge strip 4.
- the in a corresponding toothing on the Hole 6 engaging pressure cylinder serves primarily for exact transport of the material web 3.
- a perforation 10 is provided, which is a slight separation of the edge strip 4 after completion enables the printing process.
- Register mark field 2 consisting of several marks A, B, C, D for register control of top printing as well as off optionally available marks W, X, Y, Z for register control an underside print, is close to the perforation 10 the edge strip 4 printed.
- the only symbolic in Fig. 3 indicated camera 14 is preferably vertical to the surface of the material web 3 and slightly spaced to Register mark field 2, which is 3 while the material web is running in the direction of an arrow drawn in for clarification 12 moved under the camera 14.
- the image sharpness and therefore the quality of the optical resolution of the camera 14 can be expediently increase by flash lighting 19, which synchronizes with the sampling clock of the camera 14 is. This means that the camera 14 takes place with each recorded image at the same time triggering a flash.
- the flash lighting 19 expediently switched to continuous light operation.
- FIG. 4 shows an example in a simplified block diagram Arrangement of a control device according to the invention for device control and for register control of a Press. 4 is an example of the control device shown for only one impression cylinder. The remaining Printing cylinders are operated in the same way by the central evaluation unit driven.
- the camera 14 can be seen as an optical sensor, those printed on a material web Reads block marks 1 and register marks 2 and their output signal from a downstream evaluation unit 18 is processed. Digital cameras can preferably be used as cameras 14 be used.
- the evaluation unit 18 controls Operating mode II continues to be based on that of the camera 14 captured image section directed flash lighting 19 synchronous to the sampling frequency of the camera 14.
- operating element 20 indicated operating element can be between operating mode I the set-up phase and operating mode II of the printing phase can be switched.
- This switchover is carried out, for example, on a control terminal by manual Entry, but can also be done automatically after the correct position of the pressure cylinders determined and adjusted has been.
- the switching element 20 simultaneously affects that of the Evaluation unit 18 processed sensor signal of camera 14.
- a surface mode in which all individual pixel signals of the camera 14 are evaluated and used for register control of the printing press
- a one-dimensional operating mode mode I
