Definitions

  • the invention relates to a method for the synchronization of drives of a drive assembly of a material web processing printing press with at least one printing unit, wherein the synchronization includes a folding device of the printing press, and an associated printing machine.
  • the synchronization usually includes the folder or the folding unit of the printing press. This means that the folding unit must be moved or the folding rollers must be rotated by a certain angle, so that synchronization with the other drives of the drive assembly can be achieved.
  • the folding unit can only be moved with a very small differential speed to the material web to be processed, for example a paper web. This means that time passes until the synchronization is actually achieved, which in turn means that waste is produced to a considerable extent.
  • the invention is thus based on the object, an improved this process for synchronizing drives of a drive assembly of a material web processing printing press with at least one printing unit, wherein the synchronization includes a folding device of the printing press to specify.
  • the method according to the invention is characterized in that the length of the material web between the folding device and the at least one printing unit is changed in a controlled manner as part of the synchronization of the drives for at least partial synchronization of the folding device.
  • the synchronization with respect to the other drives is no longer achieved as previously exclusively by a movement of the folding unit, but instead or in addition to a possibly still taking place small movement of the folding device, the length of the material web
  • the paper web or a film web between the folding device and the nearest printing unit or with respect to and / or relative to other printing units in a traceable, controlled manner adapted and / or changed.
  • the synchronization method according to the invention has the advantage that the folding unit itself is no longer or only slightly moved so that the waste resulting from conventional methods in the context of the synchronization process waste is avoided.
  • an element a length change element
  • a device which allow to adjust the length suitably variable so as to achieve a waste-poor synchronization in individually driven web-processing machines.
  • Such a procedure is of course also possible in other machines than printing machines, provided that they contain in any way specific or excellent drives that are comparable to a folding unit or their adjustment or movement in or even when starting production problems could, so that such a move should be avoided as possible. Synchronization methods for such other machines are therefore expressly also within the scope of the invention.
  • the element or the device which allows the change of the length of the material web in the context of the method according to the invention, can be controlled electrically and / or mechanically.
  • the synchronization of the folding device can be achieved with particular advantage completely by the controlled change in the length of the material web between the folding device and the at least one printing unit, so that the folding device itself or their rollers and rollers in Frame of the synchronization process is not moved, but only an associated length-change element for the web.
  • This case represents the basic idea of the invention, namely to keep the folding units or other machines a comparable drive completely unmoved, so as to reliably exclude the emergence of waste. Instead of making a change in the position or the angular position of components of the folding unit, so only the length of the material web is adjusted as necessary, so as to achieve the required synchronization with respect to the folding unit.
  • a component of a folding apparatus of the printing machine forming element or length-changing element of the folding device can be connected upstream.
  • an element or a device is switched on, which is to be assigned to the folding apparatus as a whole with the folding device with regard to their system-related assignment.
  • the folding apparatus is thus expanded in the sense of avoiding an adjustment of the conventionally adjustable components or rollers of the folding device to such a length-changing element.
  • This element or this device can be controlled electrically and / or mechanically.
  • the control can be integrated into existing controllers in existing printing presses or can be added to a control software as a new routine or function (retrofitting).
  • a specific control device for this element is inserted or that printing presses are already made from the outset with a controller for this synchronization device.
  • the length of the material web between the folding device and the at least one printing unit can by means of a Material web storage element, in particular by means of a vertically movable member and / or a multi-component element and / or a rolling element and / or a dancer roller and / or a dancer roller-like element, and / or controlled by a control device to be changed.
  • the change in length can be carried out such that a control device transmits corresponding signals to the device or the element (s) for changing the material web length.
  • the control can optionally be organized hierarchically, so that the control signals, for example, from a central control device to a decentralized, the folding unit or the folder directly associated control device are transmitted, which then passes this as control signals to the length change element to be set.
  • the control of the material web storage element can be done completely decentralized. However, it is expedient and if necessary also necessary to provide feedback regarding the settings of the remaining drives or of some remaining drives of the drive system or the previous evaluation of signals of further drives of the network.
  • the material web storage element expediently has different possible storage positions, which are assigned to different web lengths.
  • the setting of the material web storage element which may well consist of several components, for example of several rollers, rods or struts with rollers or the like, can be carried out in steps or substantially continuously.
  • there are devices for length change which contain vertically movable elements, so that the career of the paper or the film is changed by the change of the vertical arrangement, so that this times shorter, longer, depending on which, in which Position the folding unit (or a folding roller) would have to be brought if this would be adjusted by itself, which is not or only in the arrangement according to the invention, or only in a small extent the case.
  • the vertical adjustment of the memory element ensures that the Material web, which is led around this element, no longer receives only a horizontal course, but a course with vertical "detours". It is important to adjust the web storage element so that the adjustment of a change in position of the folding unit corresponds to a certain desired extent or is equivalent to this.
  • track storage elements for example, offer dancer rollers, which can be arranged to be movable in height.
  • the web storage element may also be a combination of various components, such as an element with roll components and these connecting conveyor belts, struts, rods and the like.
  • adjustment axes or adjustment joints and / or the like are to be provided for the realization of the adjustability of the web storage element or the plurality of web storage elements.
  • the length of the material web between the folding device and the at least one printing unit can vary depending on at least one current position and / or position value of the folding device and / or the folding apparatus and / or at least one further drive and / or a length change element for changing the length of the material web the folding device and the at least one printing unit, in particular as a function of at least one angular position value and / or deflection value, are changed in a controlled manner, in particular as a function of a measurement and / or evaluation of at least one current position and / or position value as the actual value.
  • the measurement of the position of, for example, a dancer roller can take place via corresponding sensor and sensor systems.
  • the deflection of a dancer roll can be detected, for example, by means of a position measurement based on optical principles. Other position measuring systems can also be used.
  • a current angular position of a rotatable element the deflection or desired rotation of a web storage element to be assumed for the production just desired can be determined, and / or a difference to be set can be determined for the actual value.
  • At least one nominal position and / or desired position value, in particular an angular position value and / or deflection value, of at least one length change element for changing the position of the length of the material web between the folding device and the at least one printing unit can thus be determined by a control device and / or to the length change element and / or a further, the length change element associated control device be forwarded.
  • nominal lengths for the material web can be determined.
  • the control device thus preferably evaluates its supplied actual values of the positions of the web memory or the folding unit and possibly further drives and determines values to be taken for the position or the deflection of a dancer roller or other memory elements.
  • setpoints for the position of the further drives of the network can also be specified.
  • the current position or the specification of current position and position data for the extensometer also determines the cut register.
  • setpoints can also be specified for the folding unit, if their adjustability is possible in principle. In a combined adjustment of a length-change element and the folding unit itself by a small amount, it makes sense to include the folding unit in the determination of actual and target values.
  • the setpoint values for the web storage element are either determined in a central control device, which optionally also receives the actual values of the further drives, for example values of the nearest printing unit, or a hierarchical or decentralized control takes place, possibly also a decentralized control device of data of other control devices can be supplied. If the central control device determines the desired positions, it can pass on directly corresponding control signals to the web storage element, or it is conceivable that the desired values are only converted in decentralized control devices into control signals which are forwarded directly to the dancer roller or other length change elements.
  • the position and / or position of the length-change element or of the length-change elements can be changed as a function of the at least one desired position and / or desired position value, and / or the position and / or position of the length-change element or the length-change elements can be changed in dependence on a setpoint / actual value comparison ,
  • a control loop with corresponding control components is implemented, which makes it possible to use the current actual values For example, read several rolls and to generate setpoints, the correctness of the setting and / or deviations can be checked in the context of the scheme.
  • When changing production for example when changing the material web to be printed (other paper quality or thickness, etc.), completely new desired position values can be given correspondingly, which depend on the respective changed production conditions.
  • the length of the material web between the folding device or at least one printing unit is changed controlled in the context of a regulation.
  • the invention relates to a material web-processing printing machine with at least one drive assembly with a plurality, in particular by means of a method according to one of the preceding claims, to be synchronized drives and at least one printing unit, wherein the drives to be synchronized include a folding device of the printing press.
  • the printing press according to the invention is characterized in that the length of the material web between the folding device or at least one printing unit can be changed in a controlled manner as part of the synchronization of the drives for at least partial synchronization of the folding device.
  • the invention also expressly relates to other web-processing machines with special and / or excellent drives whose movement or adjustment brings problems, so that instead of the synchronization of these special drives, the length of the web between these drives and other drives of the composite is changed controlled ,
  • the printing machine according to the invention is equipped with means which make it possible to change the length of the material web with respect to the nearest printing unit or a plurality of printing units (predetermined lengths with respect to a plurality of printing units can be specified), thus allowing movement or adjustment eliminates the folding device of the folder or can be reduced to a minimum.
  • the change in length can be effected for example by the interaction of a control device with a web storage element.
  • the folding device can be synchronized completely and thus without its own movement by the controlled change in the length of the material web between the folding device and the at least one printing unit, and / or it can for controlled changing the length of the material web between the folding device and the at least one printing unit at least a part of a folding apparatus of the printing press forming element of the folding device to be connected upstream.
  • the printing press may comprise at least one material web storage element as a length change element, in particular a vertically movable element and / or a multi-component element and / or a roller element and / or a dancer roller-like element, and / or a control device, by means of and / or a controlled change the length of the material web between the folding device and the at least one printing unit can be effected.
  • a length change element in particular a vertically movable element and / or a multi-component element and / or a roller element and / or a dancer roller-like element, and / or a control device, by means of and / or a controlled change the length of the material web between the folding device and the at least one printing unit can be effected.
  • Such storage devices can also be used in printing machines with longitudinal shafts, but these serve to influence the cut register.
  • the use of web storage elements in the context of the invention, namely to avoid the movement of a folder as completely as possible and thus to produce less waste, is not yet known.
  • the printing machine according to the invention thus has, for example, a roller which is adjustable in height, so that the paper web or film web is redirected accordingly or results in a bag-shaped recess in the otherwise horizontal path, which leads to an extension of the path that the paper traversing textile web or another material web.
  • the extension can be related to a nearest printing unit but also the entire system of printing units or other drives as I said.
  • the actual specification for changing the length of the web can be determined from the angular position or position of the folding unit to be set in a conventional system. This means that the change in the path length or the travel and / or adjustment path for the storage device can be determined quasi on the basis of a virtual target position for the folding unit. But it is also possible that is not over the detour of a consideration of a required for synchronization fictitious change the position of the folding unit to be set length change of the paper web is determined, but that directly calculates the desired adjustment paths or travel paths for the memory element, for example, from the actual positions in the drive network become.
  • the length of the material web between the folding device and the at least one printing unit can be dependent on at least one current position and / or position value of the folding device and / or the folding apparatus and / or at least one further drive and / or at least one extension element of the printing press to change the length the material web between the folding device and the at least one printing unit, in particular as a function of at least one angular position value and / or deflection value, be modifiable, in particular depending on a measurement and / or evaluation of at least one current position and / or position value (one or more system components ) as the actual value.
  • the printing machine accordingly has means which make it possible to obtain the current position and / or position values of the individual To determine and evaluate drives or material web storage elements, etc., in particular measuring and / or control devices.
  • the printing press may have a control device which is designed to determine at least one desired position and / or desired position value, in particular an angular position value and / or deflection value, at least one length change element for changing the length of the material web between the folding device and the at least one printing unit. or to forward to the length change element and / or another, the length change element associated control device.

  • devices which, for example as web storage devices, can be electrically and / or mechanically controllable, so as to achieve maculaturally synchronization in individually driven web-processing machines.
  • the synchronization is preferably carried out on the basis of a setpoint-actual value comparison for the angular positions of cylindrical functional parts or other position values, so as to adjust correctly, if necessary in the context of constant corrections, for example, the deflection of a dancer roller over which the web length is changed.
  • FIG. 1 is a schematic diagram of various settings of a web storage element 2 of a printing press according to the invention shown.
  • the folding device 1 is represented by the printing press merely for the purpose of illustration (the abbreviation "FU” stands for “Folder Unit”).
  • the folding unit or device 1 is not moved according to the invention, but it is the length of the paper web between the folding device 1 and a printing unit not shown here changed .
  • the printing press on a web storage element 2, which, inter alia, two struts or rods 3 and 4, which are mutually movably connected to each other by means of a hinge member 5, so that in particular the position perpendicular to the "undisturbed” course of the material web, here a paper web 7 is changeable from provided at their ends rollers 6 or so that the angle which the struts or bars 3 and 4 include, is variable.
  • the running direction of the web 7 is indicated by the arrows 8. Is the course of the paper web 7 so without this example Web storage element 2 horizontally, so come depending on the setting of the material web storage element 2 vertical components.
  • the position or position of the material web storage element 2 shown above corresponds to a neutral position 9, the position of a first storage position 10 shown below and the lowermost position of a second storage position 11.
  • the path of the paper web 7 is the longest in the case of the first storage position 10.
  • the neutral position 9 corresponds to the case that the paper is transported directly on a path which is usually rectilinear and can therefore be defined to a certain extent as a zero position.
  • the travel extension by adjusting only the strut or the rod 3 relative to the "undisturbed" course (at the same time with respect to the neutral position 9 unchanged position of the strut 4) is comparatively low.
  • FIG. 2 shows a sketch for changing the web length turn between a folding device 1 and a printing unit to be assigned functional parts 15. It can be seen here, as in this case for synchronizing the drives according to the invention without movement of the folding device 1, the course of the web 16 by forming a bag-shaped bulge 17 so is changed so that the total length of the path of the material web 16 between the functional parts 15 and the folding device 1 is extended. By this extension of the path in comparison to the dashed lines indicated horizontal course 18 an adjustment of the folding device 1 is quasi fictitious. Such a not made here adjustment is in the FIG. 2 indicated by the arrow 21 between the zero position 20 and the one specific, from the zero position 20 deviating angular position symbolizing arrow 19.
  • the change in a position of a length-change element, not shown here, such as a dancer roller or the like, which causes the effective path length between the functional parts 15 and the folding device 1 to be extended, is thus equivalent in its effect to the adjustment of the folding device 1 itself by a certain angle and can replace one.
  • the folding device 1 according to the invention no longer has to be adjusted or moved. As a result, the generation of waste during the synchronization process is considerably reduced, since the problem that the folding device 1 can be moved to the material web 16 with only very small differential speeds no longer plays any role.
