Definitions

• the invention relates to a method for operating a device for producing printed matter, comprising a Abrolliser for providing paper to be printed, wherein the Abrolliser a printing unit is arranged downstream, which prints the paper, wherein the printing unit is arranged downstream of a sheeter, which fed him endlessly printed paper transverse to the feed direction, so that individual printed sheets are provided, wherein in particular the cross cutter is arranged downstream of a collecting unit for collecting the sheets fed thereto, wherein in particular the collecting unit may be arranged downstream of a feeder unit which aligns the collected sheets, wherein the investor unit at least one further unit for finishing the printed matter to be produced downstream, according to the features of the preamble of claim 1.
• the printing unit is fed to a continuous sheet, printed and fed to a sheeter.
• the cross cutter cuts the printed continuous paper web into individual sheets to the desired format, after which the individual sheets are processed further.
• the further processing takes place in such a way that the individual sheets are collected in the desired quantity, fed to a laying unit and cut and joined, so that afterwards the printed matter is ready.
• the print unit prints a print mark associated with a later single sheet on the continuous paper web. This print mark contains information for the cross cutter, when, that is, at which point, he should cross-cut the fed continuous paper web.
• a print mark is printed in a known manner on the continuous paper web per sheet and the position of the print mark detected by a reading device, wherein the detected print mark is a measure for synchronizing the working speeds of the printing unit and the cross cutter.
• the printing unit is designed only to print a single printed mark per sheet on the continuous paper web, which is always the same print mark.
• a print mark carries only a single piece of information which is suitable for realizing the synchronization between the printing unit and the cross cutter.
• a further disadvantage is that when the printing unit and cross cutter are synchronized via the printed print mark, a carryover can occur in the further process. This means that the printing unit and the cross cutter no longer work together in the desired shape, that is, due to this carryover, the cross cutter deviates from its once set cutting position and thus cross cuts at an undesired location.
• the invention is therefore based on the object to improve a generic method for operating a device for producing printed matter to the effect that the initially described disadvantages are avoided.
• a flexible working method for producing printed matter is to be made available.
• a digital printing unit is used as the printing unit, which prints a printed mark on the paper per sheet, or that a printed mark is present (which has already been printed in the offline mode), wherein a reading device detects the information contained in the printed mark and the cross cutter and the at least one further unit are operated in dependence on the detected information.
• the print mark according to the invention advantageously has a multi-functionality, since it contains more than a single piece of information. So far, it is known to see information as the only information in the print mark, with which the printing unit and the downstream cross cutter are synchronized with each other.
• the print mark contains at least one further piece of information with which the at least one further piece of information Unit operated, that is, can be controlled.
• Another advantage is the fact that the multi-information-containing print mark must be detected by only one reader, whereby the structure of an apparatus for performing the method for the production of printed matter can be simplified. This advantageously also simplifies a change in position of the reading device in the event that the format of the individual sheets to be printed changes, so that the printed mark can be flexibly printed on almost anywhere on the printed sheet. This flexibility can also advantageously be realized particularly simply by virtue of the fact that the printing unit is a digital printing unit, since it is possible with such a digital printing unit to change the motif, including the printed mark, which is to be printed on the continuous paper webs in an uncomplicated and fast manner.
• the cross cutter receives directly via the first information in the print mark the information (the control pulse) when it has to cut at which point, so that a lengthy synchronization can be significantly shortened or even completely eliminated. Another advantage is that it produces less rejects (up to no rejects).
• each sheet brings with it the appropriate information for further processing. That is, the information in the print mark on the one hand contains the information as to when the cross cutter is to cut the continuous paper web. However, the further information contained in the print mark is not lost but can be evaluated for the subsequent process and the units arranged downstream of the cross cutter can be operated as a function of the detected and evaluated information in the print mark. This means that each individual printed and cut sheet has its own information for further processing.
• the cross cutter are usually subordinate further units such as collecting, investor and other units depending on the product to be produced.
• the cross cutter as a further unit is a collecting unit for collecting the sheets fed to it downstream, with the information contained in the print mark the cross cutter is operated to produce individual sheets, and with at least one further information contained in the print mark, the collection unit is operated.
• This at least one further information contained in the print mark can be, for example, the page number of the printed matter to be produced. This information can be easily and simply implemented by the digital printing unit in a corresponding print mark with this information.
• the digital printing unit due to its flexibility due to the artwork, is able to repeatedly integrate the same first information in the print mark to give the cross cutter the control signal as to when to cut, and other information different in the pressure of the individual sheets integrated into the print mark to give the collection unit the control signals, when to start collecting (first page) and how long (last page) to collect. It is also conceivable not to integrate in the print mark as described above a numerical value for the page number in the print mark, but to provide as further information to the collection unit information as to how long, that is how many individual sheets to be collected in a row, until the final number of sheets to be collected is reached.
• the collecting unit is arranged downstream of a feeder unit which aligns the collected sheets, with the information contained in the print mark information of the cross cutter and at least one further information contained in the print mark, the application unit is operated.
• the units with the information read or additional information can control the entire process. Either change the number of sheets, for example, or / and donate another envelope or the like. It is important to provide the functionality (information content) of the mandatory print mark (in order to be able to cut the sheet in the register) with additional information that can change the current process.
• the cross cutter as a further unit directly and / or indirectly at least one switch downstream for discharging individual or several collected sheets, with the one contained in the print mark information of the cross cutter and at least one further information contained in the print mark at least a switch is operated.
• the cross cutter downstream units (such as the collecting or investor unit), that is indirectly, to arrange a switch to take over this switch proofs for quality evaluation or the like.
• the production process of a printed matter is thereby brought out of tact, so that it is necessary to always discharge a corresponding number of sheets corresponding to the number of finished printed matter.
• the units arranged downstream of the cross cutter, including the at least one switch can be operated in an advantageous manner. Because with this further information contained in the print mark, it is possible that the digital printing unit on the one hand prints as much sheets more than to be discharged via the at least one switch.
• the cross cutter is not only known by the first information contained in the print mark, when he should cut, but the downstream units is also known due to the further information contained in the print mark, which sheet further processed and which sheet should be discharged. As a result, the entire production process of the printed matter can be made very flexible.
• the digital printing unit Because it is possible, for example, at any given time the digital printing unit to give the command to integrate such additional information in the print mark, with a corresponding print mark is printed on the continuous paper web and processed further.
• This further information in the print mark In the subsequent processing process, for example, the sheet which has been cut by the cross cutter is not fed to the collecting unit, but is discharged via a switch located between the cross cutter and the collecting unit. It is also conceivable to provide a print mark with such further information that individual sheets are cut and collected in a corresponding number of the printed matter to be produced and then fed to the feeder unit. Since the print mark in this case contained the information that it is a proof print, the pickup unit can evaluate this contained in the print mark further information and give the subsequent switch command to eject the collected sheets. Before and after, the actual process for producing the printed matter continues unchanged.
• the information contained in the print mark controls the beginning and the end of the collection of the sheets.
• the digital printing unit generates a print mark which, as already described, contains the first information as to where the cross cutter should cut the printed continuous paper web fed to it.
• the at least further information includes when the start (first sheet of the print job) and the end (last sheet of the print job) of the collection are. Before or in between, it is possible for the digital printing unit to flexibly integrate such information into the print mark which has the content, whether a respective sheet is to be further processed (in particular collected) or ejected.
• the method according to the invention also has the advantage that it is not only possible to provide paper from a unwinding unit, this continuous paper is fed to the digital printing unit, printed and fed to the cross cutter for cutting (so-called online operation), but that it is also possible to first provide continuous paper from the unwinding unit of the digital printing unit, to print and to wind it up, and then to feed this printed continuous paper web to the cross cutter for further processing for producing the printed matter at another location or at a later time (so-called off-line operation).
• the basis for the present invention is a device 1 for digital printing.
• the starting point for this printing process is a unwinding unit 2 of the device 1, on which a paper roll is held in a manner known per se and unrolled in accordance with the subsequent printing process.
• the subsequent printing process is carried out by a digital printing unit 3, which is arranged downstream of the Abrollisme 2 and the paper rolled there is fed for printing.
• the unrolled from the unwinding unit 2 and the digital printing unit 3 supplied paper is first printed and leaves the digital printing unit 3 in the form of a quasi-endless web.
• This quasi-endless web is fed to a cross cutter 4, which cuts across the quasi-endless web that is printed according to the predetermined format of the printed matter, thereby initially setting a format of the later printed matter (optionally with the addition of tolerances) becomes.
• the collecting unit 5 in turn is followed by a feeder unit 6.
• This feeder unit 6 causes, when the collecting unit 5 is present, the individual sheets provided there to be stacked into a desired pile, that is, to be collected while being put together in a position where the further processing is to take place. If the collecting unit 5 does not exist, it is conceivable that the printed matters leaving the cross cutter 4 are fed directly to the feeder unit 6.
• the investor unit 6 may, but need not be followed by a switch 7. With this switch, it is possible to eject test prints, for example, to check for quality of the printing process out.
• a stapling and folding unit 8 With this unit 8, the hitherto located in the pile printed matter depending on the desired format of the finished printed matter stapled and / or folded. Other forms of bringing together the individual sheets of the printed matter are of course also conceivable.
• the individual sheets of printed matter After the individual sheets of printed matter have been brought together permanently, they are fed to a cutting unit 9. By means of the cutting unit 9, the added tolerances of the individual merged sheets of printed matter can be cut to the finished format of the final printed matter.
• a discharge unit 10 In which the finished printed matter for further use, for example, the package in desired containers, are supplied.
• the digital printing unit 3 is the master for the entire printing, cutting and filing process.
• the units following the digital printing unit 3 are interconnected as a siave. This means that the digital printing unit 3 as master sets the clock for the subsequent processes and these must be based on the predetermined clock of the master.
• a quasi-endless paper sheet with a predetermined width of the digital printing unit 3 is supplied.
• a register mark is printed in addition to the actual printed matter on the paper by means of the digital printing unit 3. With this register mark recognizes the subsequent cross cutter 4, at which point the supplied quasi-endless web must be cut across.
• This printed matter may be one, two or more than two. This means that on the sheet leaving the cross cutter 4, a single page of a later finished printed matter with a given length and width is available. Often, however, a printed sheet will be available which includes two or more sheets of printed matter to be finished later.
• a print mark (register mark) is removed at a predeterminable distance (for example a maximum of 50 mm) from the leading edge of the sheet (sheet travel in the device 1). Then the device 1 can eject a faulty sheet or, if the tolerance window has not been reached, with the built-in switch 7.
• the cross cutter 4 and the following units up to the outlet unit 10 can be controlled individually by means of actuators by the control unit 11 with regard to the processing format of the sheets fed. It is thus possible, via a single command of the control unit 1, to control the units controlled by it, in particular the cross cutter 4, the collecting unit 5, the feeder unit 6, the stitching and folding unit 8 and the cutting unit 9 to switch from a given, especially previously processed format, to a different format. For example, it is possible for the digital printing unit 3 to print sheets that correspond to the other two-size format. These sheets are processed by appropriate format setting of the subsequent unit. If a changeover from a two-in-one format to a three-in-one format is now to take place, this can be done centrally by the control unit 11.
• This process can be arbitrarily controlled by a corresponding input in the control unit 11.
• a corresponding input in the control unit 11 Of particular advantage is the switching within a useful, saunutzigen and maximally dreinutzigen formats, as this, the cost of actuators and the structural conditions in the respective units and, where appropriate, the associated sensors that detect the switchover from one to the other format, manageable remains.
• the digital printing unit 3 can provide the printed sheets, depending on the provided printed quasi-endless web leaving the digital printing unit 3, the subsequent units of these printed sheets in response to the clock at which this digital printing unit 3 leave, process.
• the flexible timing of the subsequent process has the particular advantage that withdrawals of sheets on the switch 7, but also other disturbances (for example paper jam) in the process nachgeschaitet the digital printing unit 3, can be compensated or compensated without the entire device 1 to stop.
