Definitions

  • the present invention relates to a variable-format device for cutting printing materials, in particular for use in a variable-format cutting and folding apparatus or designed as a variable-format cutting and folding apparatus, in particular for use in a variable-format printing press, in particular such a web-fed printing press.
  • Web printing machines are basically known from the prior art, for example from standard textbooks on web offset printing. For example, from Wolfgang Walenski, Der Rollenoffset réelle, 1995, pp. 90 - 95, web printing machines for illustration printing and newspaper printing are known, and from pages 98 - 103, for example, web printing machines for book printing are known. Such web printing machines are also known from Helmut Teschner, Offsettiktechnik, 1997, pp. 10/25 - 10/28 and web printing machines for book printing are known from Teschner pp. 10/76 - 10/82.
  • Web printing machines are also used for book printing DE 40 30 863 A1 known, where a web-fed rotary printing machine is described which has two successive longitudinal folding devices with two folding formers, the first longitudinal folding device being arranged rotated by 90 ° relative to the second.
  • the above-mentioned web printing machines are all designed as rotary printing machines, so they use rotating printing cylinders in the form of plate cylinders that carry printing plates and in the form of transfer cylinders or rubber cylinders that transfer the printing ink from the plate cylinder to the paper web to apply printing ink to a paper web.
  • Helmut Teschner, Offset Printing Technology, 1997, p. 10/76 already addresses the problem of process engineering Disadvantages due to fixed cylinder circumferences are pointed out, but web offset printing machines are still used there, i.e. web printing machines that have rotating printing cylinders.
  • printing units and also folders with a fixed cylinder circumference and thus a fixed printing section or printing format are used in web printing machines, in particular in letterpress web machines. Since the plate cylinders and transfer cylinders or blanket cylinders have a fixed, defined circumference, the associated folders are also set up for these fixed circumferences and thus fixed print formats. This means that the print formats and printed products that can be produced are always the same throughout the entire lifespan of the web printing machine, determined by the fixed circumferences of the cylinders. However, such fixed formats cannot be used economically and/or technically optimized, especially for small runs (e.g. less than 1000 pieces) and very small runs (e.g. less than 100 pieces).
  • the manufacturing costs of printing plates and the set-up time when changing printing plates also have a much greater percentage impact on the manufacturing costs of the printed products for smaller runs than for printed products that are always printed in the same print format in large runs (e.g. thousands of copies).
  • the same can also apply to newspaper printing and illustration printing with short runs and very small runs, especially for contract printing companies that have to provide constantly changing print products on behalf of a large number of customers and publishers.
  • the object of the present invention is to provide an improved device for cutting paper webs or a folder. This task is solved by the features of patent claims 1 - 4.
  • Embodiments of the invention are described below. These embodiments can be provided individually or in combination with any further embodiment of the invention, i.e. in principle all suitable combinations of the technical features described below are possible with one another to further develop the invention.
  • One possibility of combining the technical features to design the objects of the invention is represented by the dependent patent claims.
  • a variable-format printing press in particular a web-fed printing press, has printing units having printing devices or groups of printing devices for applying printing ink to a printing material or a paper web. It can be provided that the printing devices or groups of printing devices are all designed to be free of rotating printing cylinders.
  • the printing units for applying printing ink can also be suitable for applying any other type of liquid substance a paper web is to be applied, such as varnish, liquid glue, dampening solution or other printing inks such as toner-based printing inks or similar. Because there is no need for a rotating printing cylinder, the device can free itself from the constraint of fixed cylinder circumferences, which always limit printing formats to fractions of the cylinder circumference (1, 1 ⁇ 2, 1/3, 1 ⁇ 4, etc.).
  • the printing material and in particular the paper web on a roll does not have this restriction, since it has a practically "infinite" extent - limited only by the web width of the printing material or the paper web - and allows the printing of any format size.
  • a format-variable printing machine in particular a format-variable web printing machine, is made possible, which can print a wide variety of printing formats.
  • the print formats of a printed image or a printed page can be determined in particular by the length (extension in the running direction of the printing material or the paper web) and/or the width (extension in the direction transverse to the paper web), but also by the orientation (distance of the printed image from the edge of the paper web, distances between the printed images, angle between the longitudinal edge of the printed image and the direction of travel of the printing material or the paper web) on the printing material or the paper web.
  • the printing devices or groups of printing devices can be designed for the contactless application of printing ink to the printing material or the paper web. These can be designed in particular as a device for dripping or spraying printing ink with the aid of a drip device or nozzle device, for example in the form of an inkjet device. This avoids direct contact between the printing material or paper web and printing devices and enables variable-format application of printing ink to the printing material or paper web.
  • the printing devices or groups of printing devices can also be designed for the contactless application of toner-based printing ink to the printing material or the paper web.
  • control device for controlling and/or regulating the printing devices or groups of printing devices and for controlling and/or control of an actuating device of at least one cutting device for cutting at least part of the printing material or the paper web, the control of the actuating device taking place as a function of print format settings for the printing devices or groups of printing devices.
  • the running direction of the printing material or the paper web in the sense of this invention does not define a global fixed plane in space, because the printing material or the paper web undergoes several changes of direction and possibly also wraps, as the figures clearly show.
  • a person skilled in the art can determine a clear spatial direction from the local running direction of the paper web locally - i.e. for each web section of the printing material or the paper web.
  • control device is designed to control and/or regulate a motor actuating device of a cutting device with cutting knives.
  • the motor actuating device can be designed, for example, as a drive motor or servomotor.
  • control device is designed to control and/or regulate the actuating device as a function of pre-stored or pre-calculated control curves.
  • control curves can define a local and/or temporal course for the operating state of the actuating device, i.e. the operating state or operating parameters (such as pressure, intensity, force, speed, spatial position, clock frequency) of the actuating device can be determined locally or temporally with the help these control curves can be changed.
  • the cutting device is designed as a rotating cutting device and the control device for controlling and/or regulating the actuating device is designed such that the cutting device can be operated with varying angular speed per revolution.
  • the angular velocity (or the tangential component of the rotational speed in the running direction of the printing material or the paper web) of the cutting knife is equal to the conveying speed of the printing material or the paper web.
  • the rotational speed is therefore adjusted per revolution of the rotating cutting device so that, at least when there is contact between the cutting knife and the paper web, both are at the same speed, so that there is no relative speed between the two at the contact point. This prevents the printing material or paper web from tearing or picking.
  • the printing devices or groups of printing devices have a nozzle device for spraying printing ink onto a printing material or a paper web, for example in the form of an inkjet device or that this has a toner device for applying toner-based printing ink have a printing material or a paper web.
  • printing devices or groups of printing devices or web guide elements adjacent to the printing devices are mounted displaceably perpendicular to the web plane for guiding the printing material or the paper web. This can be used in particular for the relative alignment of the printing devices or groups of printing devices or the web guiding elements to one another and/or relative to the printing material or to the paper web.
  • printing devices or groups of printing devices or web guide elements adjacent to the printing devices for guiding the printing material or the paper web can be displaced perpendicularly to the web plane in a controlled or regulated manner by a control device in such a way that a predefined distance between the printing material or the paper web and the printing equipment is adhered to. This may be necessary in particular for printing devices that have a nozzle device.
  • printing devices or groups of printing devices are arranged one behind the other in the running direction of the printing material or the paper web. This can be used, for example, to print several colors one after the other.
  • the individual printing devices of a group of printing devices are each designed to apply different printing inks. In principle, it can therefore be provided that printing devices only print the printing material or the paper web with a single printing ink. However, it can also be provided that printing devices are provided for printing different printing colors, with certain printing devices for printing different printing colors being combined into a group. These groups are characterized, for example, by a similar spatial arrangement or a common control.
  • At least one dryer is provided, which is arranged downstream of at least one of the printing units in the running direction of the printing material or the paper web. This makes so-called heatset production possible in particular.
  • the dryer is structurally integrated into a printing unit. This enables a particularly compact structural or spatial design of the printing unit and dryer.
  • the dryer is structurally or spatially integrated into a printing unit in such a way that the dryer operation does not influence the printing devices.
  • the dryer can cause interference such as heat radiation, vibrations, electromagnetic fields or the like, which can influence the function of the printing devices.
  • This configuration prevents the dryer from having a disruptive influence on the printing devices, for example through suitable spatial separation or distances, a suitable relative spatial arrangement of the dryer and printing devices to one another or through suitable shielding.
  • the dryer can be arranged, for example, below the printing devices. Depending on the type and design of the dryer, there could be a risk that the heat generated rises and heats up the printing devices in an undesirable manner. It can therefore be provided that the dryer is arranged spatially above the printing devices of a printing unit.
  • a folding apparatus can also be provided, which is arranged downstream of the printing units and which can have several folding devices arranged in a row or parallel to one another in the running direction of the printing material or the paper web.
  • This configuration of the folding apparatus in combination with an object of the invention - and possibly its further configurations as described so far - results in a particularly favorable synergy, especially for a variable-format printing process.
  • Through the two folding devices exist Great freedom for product design and product processing of printed products, especially for format-variable printing processes.
  • the arrangement of the folding devices and the web guidance of the printing material or the paper web in the folding apparatus are set up in such a way that the fold lines already mentioned above each define the fold of the printing material or the paper web by one of the folding devices.
  • it can be achieved that unprinted or overprinted areas of the printing material or the paper web are aligned precisely in such a way that they are placed on a fold of the printed products and are therefore not disturbingly noticeable in the finished printed product.
  • one or each folding device is displaceable in at least one spatial direction, the first folding device being displaceable in a first spatial direction and the second folding device being displaceable in a spatial direction perpendicular thereto.
  • the state of the art DE 40 30 863 A1 On the other hand, only one of two folding formers can be moved, the other folding former is fixed. The design described here thus offers improved freedom in the alignment and adaptation of the folding devices to a wide variety of print formats and widths as well as guides of the printing material or to paper web widths or paper web guides.
  • the post-processing device cutting devices, web or sheet guides, grippers, etc. downstream in the running direction of the printing material or the paper web is not or only barely adapted to changed print formats and widths as well as guides of the printing material or paper web widths or paper web guides (e.g. spatially shifted). Rather, this can be achieved via the displaceability of the folding devices.
  • At least one folding device can also be displaced in the second or in a third spatial direction, which is perpendicular to the first spatial direction.
  • This variability of the folding device further improves the alignment and adjustment of the folding devices to a wide variety of print formats and widths as well as guides of the printing material or paper web widths or paper web guides.
  • a symmetrical or asymmetrical web guidance of the printing material or the paper web by the printing devices with simultaneous variability of the web widths and printing formats can be compensated for by the two-axis displaceability, ensuring that the post-processing device (cutting devices) downstream in the running direction of the printing material or the paper web , web or sheet guides, grippers, etc.) do not have to be adapted (e.g. spatially shifted) to changed print formats and widths as well as guides of the printing material or paper web widths or paper web guides.
  • the folding apparatus has a sheet or paper sheet transport element with a drive, the drive being regulated by the control device or a separate control device in such a way that sheets or sheets separated from the printing material or the paper web are produced by the cutting device .
  • Paper sheets are accelerated away from the remaining printing material or the remaining paper web in the running direction of the printing material or the paper web. This ensures in particular that paper sheets separated from the printing material or the paper web are spatially separated by a defined amount from the remaining printing material or the remaining paper web or subsequent separated paper sheets after the cutting device. This makes it easier for these sheets or sheets of paper to be recorded and/or processed separately in the post-processing device.
  • a device with a drive is arranged downstream of the sheet or paper sheet transport element, the drive being regulated by the control device or a separate control device in such a way that the transport movement of the previously accelerated sheets or paper sheets is slowed down . This can in particular ensure that separate sheets or sheets of paper are collected in order to produce multi-layered products, for example.
  • the aforementioned device is designed in such a way that, in addition to slowing down, at least some of the sheets or sheets of paper are raised or lowered to scale up the sheets or sheets of paper.
  • raising or lowering of at least some of the sheets or sheets of paper for example the front edge or trailing edge (seen in the running direction of the printing material or the paper web), makes it easier for the sheets or sheets of paper to pile up, since subsequent sheets or sheets of paper are then raised above or beyond be routed under previous sheets or sheets of paper.
  • a folding former - and possibly also other folding devices - can be dispensed with, since the required product width is achieved by separating the printing material or the paper web into partial webs and the required product length is achieved by the cutting module for separating sheets or Sheets of paper are produced.
  • the sheets or sheets of paper produced in this way can be collected, stacked and/or laid out to form products. This makes it possible for the printing units shown above to interact very easily with a web turning device and a post-processing device.
  • a variable-format printing machine in particular a variable-format web-fed printing machine, can be provided, such as a letterpress web-fed press, a variable-format newspaper-fed web press or a variable-format illustration web-fed press, which in particular can be designed or further developed according to one or more of the previously described technical features, comprising printing devices such as inkjet or toner printing devices or groups of inkjet or toner printing devices and a control device for controlling and / or regulating the printing devices or groups of printing devices and for controlling and / or regulating an actuating device of at least one cutting device, the control of the Actuating device takes place depending on print format settings for the printing devices or groups of printing devices.
  • Inkjet or toner printing devices are a realization of printing devices, all of which are designed without rotating printing cylinders and at the same time of printing devices or groups of printing devices for the contactless application of printing ink to the printing material or the paper web.
  • the design of the control device described here for controlling the printing devices or groups of printing devices and for controlling an actuating device of at least one cutting device results in a particularly favorable synergy, in particular for a format-variable printing process.
  • Precisely the use of knowledge of the print format settings for the printing devices or groups of printing devices to control an actuating device of at least one cutting device in a - in particular common - control device ensures optimal and print format-compliant adaptation of the entire printing and processing process.
  • Variable format roll machine in the sense of the invention means that the print format settings of printed pages and/or printed images on the printing material or the paper web - in particular regarding length (extension in the running direction of the printing material or the paper web) and/or width (extension in the direction transverse to the printing material or to the paper web) and/or alignment (distance of the printed image from the edge of the printing material or the paper web, distances between the printed images, angle between the longitudinal edge of the printed image and the running direction of the printing material or the paper web - can be varied within wide ranges , essentially only limited by the width of the printing material or the paper web used.

  • an actuating device of a rotating cutting device can be controlled by a control device in such a way that the cutting device can be operated with varying angular speed per revolution. It can also be provided that when a cutting knife comes into contact with the printing material or the paper web, the angular velocity is equal to the conveying speed of the printing material or the paper web. So the rotational speed is adjusted per revolution of the rotating cutting device so that at least when there is contact between the cutting knife and the paper web, both are equally fast, so that there is no relative speed between the two at the contact point. This prevents tearing or picking.
