Definitions

  • the invention relates to a device and 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 cross cutter, the him endlessly supplied printed paper transverse to the feed direction, so that individual printed sheets are provided, wherein the cross cutter is arranged downstream of a collecting unit for collecting the sheets supplied to him, wherein the collecting unit (which aligns the collected sheets) may be arranged downstream of an investor unit, said the investor unit at least one further unit for finishing the printed matter to be produced is arranged downstream, according to the features of the respective preamble of the independent claims.
  • the invention is therefore based on the object to provide a device and a method for operating such in particular for digital printing, with a quick conversion to adapt to the format of the subsequent printed matter is possible.
  • This object is achieved according to the invention by virtue of the fact that upstream and / or downstream of the cross cutter the actuators are associated with actuators by means of which the processing of the fed sheets in these units is set from one format to another format.
  • the actuators also movably arranged sensors, in particular arranged in front of the cross cutter sensors moves, i. be adjusted to give the downstream units or their actuators information about a changed format (such as the width of the paper to be printed), so that by means of the downstream units associated actuators and the changed format can be adjusted.
  • a changed format such as the width of the paper to be printed
  • format is initially understood to mean the format of the sheet of the paper to be printed, in particular length and width, and paper type and paper thickness, but also the format of the product to be produced or later finished, ie length, width, finished width Per Product, thickness of the paper, number of sheets to be collected (determines the page number), thicknesses of the supplied additional materials (such as cover thicknesses, where the necessary adjustments are to be performed sequentially at the right time), binding method, number of subsequent processing steps (for example, with or without Corner rounding, inserting reinforcing strips etc.
  • a control unit in which the conversion from one format to the other format is specified, wherein the control unit activates the actuators in the respective units in such a way that they process the sheets supplied to them in the predetermined format.
  • the control unit activates the actuators in the respective units in such a way that they process the sheets supplied to them in the predetermined format.
  • the respective units are also suitable and adapted to change their structural elements their previous position corresponding to the one format by the control and the movement of the actuators, and thus to assume a position corresponding to the changed format. These positions can be realized by linear displacements, rotational movements or combinations thereof.
  • the conversion from one format to the other format involves format changes in, for example, the length and / or width of the paper sheet, the type of paper, the type of printing (eg, single-sided or double-sided printing), paper thickness, and the like ,
  • By equipping the device for producing printed matter by means of actuators not only the greatest possible flexibility is realized, but it also eliminates a time-consuming conversion of the entire device in the case of format changes, so that such a device can be operated much more flexibly and cost-effectively. This is particularly advantageous when printing series of small numbers to be produced.
  • a control unit of the printing unit is connected to the control unit, wherein the conversion is predetermined by means of the control unit of the printing unit. Due to the printing of the endlessly supplied paper in the printing unit, it may be necessary for the format setting of the units downstream of the printing unit to be changed. In this case, it is advantageous if the format change via the control unit of the printing unit is specified and receives the information about the setting to be made via the control unit of the printing unit, the control unit, which adjusts the actuators of the downstream units. In addition to the central specification of the format change over a single higher-level control unit, it is thus possible to make a decentralized format changeover, in particular via the control unit of the printing unit.
  • the method is provided to solve the problem that when a change from the one format of a sheet is specified to another format, by means of actuators in the respective downstream of the cross cutter units, a change of the format is done automatically.
  • a device for producing printed matter can be operated in a particularly flexible and cost-effective manner, since it is possible to respond quickly to format changes without the need for time-consuming and costly conversion work.
  • the automatic conversion of the format is considered in the feed direction with respect to the width of the sheets. While the length of the sheets viewed in the feed direction can be adjusted by the corresponding control of the cross cutter, can be achieved by the automatic conversion S of the format in the feed direction to under defenceiiche widths are reacted by the automatic adjustment by means of the actuators. This makes it quick and easy to produce different formats of series of printing series.
  • a method for operating a device for producing printed matter comprising a Abrolliser for providing printed paper, wherein the Abrolliser a cross cutter is arranged, which intersects him endlessly supplied printed paper across the feed direction, so that individual printed sheets be provided, wherein the cross cutter a collecting unit for collecting the sheets supplied to it is arranged downstream, wherein the collecting unit can be arranged downstream of an investor unit, wherein the investor unit is arranged downstream of at least one further unit for finishing the printed matter, wherein collaboratingd then if a conversion of one format of a sheet is given to another format, by means of actuators in the respective cross-cutter front and / or downstream units, preferably downstream units, the format is automatically changed.
  • the continuous paper roll has printed matters of a different format (such as one or more printed matters first in the form of prints on the continuous paper web cut into individual sheets and finished, these plural printed matters in the one format will have one or more printed matters in one of them follow different format), these different printed matter can be fed to the prepared continuous paper web to the cross cutter and the downstream units and quickly processed and completed as a result of format adjustment according to the invention. It is also conceivable to use a device with a digital printing unit, but in this case does not print and through which the printed Endlospapierbahn is merely performed.
  • the format change according to the invention has the decisive advantage that the entire device does not have to be manually rebuilt (which can take several hours, if not days) to perform a format change, but that the format change within a very short time (depending on the design of the device less than three hours, preferably less than one hour, more preferably less than half an hour and more preferably less than a quarter of an hour or less than 50% or preferably 10% of the previous manual changeover time) by means of the control of the actuators.
  • the basis for the present invention is a device 1, in particular for digital printing.
  • the invention can also be applied to other printing units.
  • the subsequent printing process is carried out by a digital printing unit 3, which is arranged downstream of the Abrolliser 2 and the paper rolled there is fed for printing.
  • the unrolled from the unwinding unit 2 and supplied to the digital printing unit 3 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.
  • a collecting unit 5 After the cutting process of the cross cutter 4 this is followed by a collecting unit 5.
  • This collecting unit 5 In this collecting unit 5, individual pages of the printed matter to be finished later can be collected.
  • 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.
  • 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.
  • the 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 At the end of the cutting unit 9 is followed by a discharge unit 10, in which the finished printed matter for further use, for example, the package in desired containers, are supplied.
  • a quasi-continuous paper sheet having a predetermined width is supplied to the digital printing unit 3.
  • 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.
  • a printed matter is available , 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.
  • the cross cutter 4 and the following units up to the outlet unit 10 can be individually controlled by means of actuators by the control unit 11 with regard to the processing format of the fed sheets. It is thus possible, via a single command of the control unit 11, to command 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, from a predetermined one , in particular previously processed format, to switch 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.
  • 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, which is the digital printing unit 3 downstream, can be compensated or compensated without the entire device 1 to stop.
