Definitions

  • the invention relates to a sheet-fed printing machine comprising a false sheet sensor, according to the preamble of claim 1.
  • substrate sheets are each held ready for processing in a feeder stack.
  • the substrate sheets are lifted individually from the feeder stack with the aid of suction devices, usually designed as a suction head with separating and transport suction devices, and conveyed to a belt table by means of a clock conveyor device.
  • the cycle conveyor is normally designed as an arrangement of at least two cycle rollers in a symmetrical arrangement to the machine width over a belt roller or transport roller.
  • the timing rollers are set down by a timing shaft in the cycle of the sheet processing machine on the belt or transport roller and clamp the substrate sheets there individually or in a layered position.
  • the substrate sheets are then moved forward at a predetermined speed in synchronism with the machine operation.
  • the substrate sheets are then deposited over the belt table on a positioning device designed as a positioning table for aligning the substrate sheets.
  • the substrate sheets are fed from the feed table to a sheet feed device of the sheet-fed printing machines.
  • the substrate sheets lifted from the feeder stack are usually fed in an imbricated sheet position as an imbricated stream of the sheet feeder via the belt table.
  • the imbricated flow is formed during separation from the stack of sheets by the suction devices pushing the front end of a subsequent sheet in the area of the cycle conveyor device under the end of the substrate sheet running ahead when the cycle rollers are raised.
  • a false sheet is about a double sheet made up of two congruent or possibly slightly shifted one on top of the other substrate sheets, the feeding of which into the sheet-fed printing machine can damage the same or interfere with the smooth execution of the print job.
  • False sheets are substrate sheets that differ in one property from a properly fed substrate sheet. In addition to double sheets, this also includes missing sheets, i.e. non-existent substrate sheets, multiple sheets consisting of more than two substrate sheets, oblique sheets whose leading edge deviates from the ideal position, early sheets that arrive before a target time, late sheets that arrive after a target time, thick sheets with larger or thin sheets with a smaller sheet thickness than the specification.
  • Mechanically acting devices are mostly used for double sheet detection, which mechanically scan the imbricated flow to be checked.
  • a very precisely manufactured scanning roller which is connected to a microswitch, also rolls on the surface of the imbricated flow in addition to the timing rollers.
  • the scanning roller causes markings on the substrate sheet, although the scanning roller is only set against the imbricated flow with a minimum amount of force in order to obtain a meaningful control result.
  • the disadvantage is the increased effort for the high-precision manufacture of the scanning roller and the parallel arrangement of several roller systems for conveying and monitoring.
  • the device learns the height contour by touching it and adjusts the roll height dynamically with piezo actuators for the further course of the sheet monitoring process.
  • the timing roller then normally no longer touches the sheet flow.
  • a pushbutton element is provided which is equipped with an actuator can be shifted in the sheet running direction. However, it can also be used at a fixed position.
  • a measurement of the contact pressure of the timing roller can be provided.
  • An inductive measuring system or a force measuring system can be provided here. Contact measurement should take place in a position-controlled manner, with the contour of the arc flow being followed.
  • a device for double sheet control with an additional feeler element in the form of a roller connected to a switching element is known. At least two probe elements should therefore be provided, with manual adjustment being carried out.
  • the feeler element as a roller does not rotate when an arc current is scanned during functional operation. The measurement is uncertain.
  • the solution concerns a false sheet sensor which has a measuring capacitor for false sheet detection.
  • the measuring capacitor is formed by two opposing measuring electrodes that together define a capacitor space, and substrate sheets are moved through the capacitor space for false-sheet detection.
  • the timing roller is mentioned as the measuring location, it only fixes the imbricated flow in order to then measure it capacitively in parallel. The measurement effort is increased because the measurement system also measures the imbricated flow directly, with the measurement configuration being constantly changed.
  • a control device for the supply of sheets is known.
  • a measuring device also detects a size that increases with the number of sheets lying on top of one another.
  • An evaluation device emits a signal when irregularities occur.
  • a pulse generator emits start and end pulses in time with the sheet feed.
  • An electronic memory is erased by the initial pulse and the values recorded by the measuring device are added up in the memory. The end pulse initiates a comparison of the stored value with a reference value for the size of the sheets lying on top of one another.
  • a method for setting a double sheet control device on the feeder in a sheet-fed rotary printing press is known.
  • the double sheet control device scans the surface contour of a shingled sheet stream in time with the machine.
  • An interfering signal is output if the double sheet monitoring device detects an impermissible number of sheets lying one on top of the other in a defined query window.
  • the length of the sheets to be processed is entered into the double sheet control device, so that an automatic setting of a query window for the double sheet query is made depending on the sheet length.
  • the object of the invention is therefore to improve a device for incorrect sheet detection and, in particular, for double sheet sensing, the aim being to simplify the device to a large extent in terms of structure and operation. According to the invention, the object is achieved with the features according to claim 1.
  • a false sheet sensor in a sheet-fed printing machine, which has a measuring device for false sheet detection in connection with at least one timing roller.
  • the substrate sheets to be monitored are moved by at least one timing roller in an imbricated flow to the sheet processing machine, in that the timing rollers interact with a belt roller or transport roller assigned to a belt table.
  • the measuring devices are used to record the support height of the timing rollers on or above the belt roller or transport roller, starting from an idle roller. If at least two measuring devices are arranged during sheet conveyance, the contour of the imbricated flow can be scanned in at least two parallel measuring tracks.
  • the measuring device assigned to a timing roller is designed to act magnetically, the position of a signal magnet being scanned by one or more measuring devices designed as Hall sensors. Such a measuring device is very reliable and robust.
  • the measuring device can advantageously be designed to be self-adjusting and operated fully automatically, whereby it calibrates itself independently and automatically by means of signal-processing algorithms.
  • the measuring device can be retrofitted on the machines mentioned and / or exchanged for conventional devices for double sheet sensing.
  • the functionality of the measuring device is advantageously implemented with high precision by means of redundantly acquired measured values for position information and by using signal-processing, recursive algorithms. In this way, the effects of inaccuracies in any mechanically individual constellation and devices with inaccuracies can be eliminated.
  • the device according to the invention it is also possible, by evaluating the timing roller height signals, to determine all information relevant for further signal processing, in particular also machine angle information required for the position assignment.
  • the measuring device can adapt itself to changes in the thickness of the printing material in an automatic sequence.
  • the timing rollers for conveying the substrate sheets away from the sheet feeder of the sheet-fed printing machine perform a tactile movement as the first mechanical access.
  • the tactile movement takes place to make contact with the individual sheets, which are guided as an underlayed sheet stream.
  • the two rollers are raised for a machine angle of approx. 100 °.
  • a separating device of the sheet feeder pushes a following sheet of substrate under a preceding sheet of substrate. Then the timing rollers are lowered onto the imbricated flow against the belt roller or transport roller and clamp the imbricated flow in frictional engagement against the transport roller.
  • the timing rollers are sufficiently soft and geometrically designed in such a way that markings do not appear on the substrate sheet.
  • the thickness of the stacked substrate sheets conveyed from the sheet feeder to the machine in a shingled arrangement is detected, fully automatic incorrect sheet detection is possible.
  • the corresponding corresponding measurement information is available with a normal process with execution of approx. 3 machine revolutions. Otherwise there are in continuous operation in the transport area between the feeder and the sheet processing unit Machine constantly about 5 sheets. This means that the position of the substrate sheets present in the imbricated flow is already known at the start of production, before the substrate sheets are taken over by a sheet feed device, such as a pre-gripper, for transfer to the sheet processing machine.
  • the measurement signal which corresponds to the total thickness of the substrate sheets lying on top of one another, is recorded continuously and, after appropriate processing, is stored in a sequential memory.
  • a software-based algorithm evaluates the signal profile recursively and uses the measured values to determine whether incorrect sheets were present at any point in time during the overlapping flow scan. Furthermore, it is reliably detected where the false sheets, derived from the contour of the imbricated flow, are present at a certain point in time in the further course of the sheet transport.
  • the signal acquisition can be related to the machine cycle by synchronous recording of machine angle information or back calculation on the basis of measured value information that is characteristically present in the measured signal.
  • the drop-off point of the timing rollers is suitable for this as the start of an arc cycle that occurs at certain machine angles per machine revolution.
  • a device for conveying sheets and for detecting the sheet position of the sheet is shown schematically.
  • the sheets can be designed as substrate sheets made of paper, plastic, cardboard or metal and are shown here on part of their transport path from a sheet feeder in a sheet transport direction R.
  • the detection of the sheet position relates to the individual sheets of an underlayed sheet stream.
  • the desired information on the sheet position is derived from the signal curve of a thickness measurement of the underlayed sheet flow or imbricated flow.
  • substrate sheets B1, B2, B3 are indicated, which are fed to the measuring and conveying device in the sheet transport direction R after they have previously been separated in the sheet feeder.
  • the sheets B1, B2, B3 are then transported over a belt roller 2 by means of a timing roller 3 onto a conveyor table 1 and then forwarded on the conveyor table 1 to the sheet processing machine arranged below.
  • the substrate sheets overlap depending on a mostly machine-specific imbricated distance between the leading edges of the substrate arches. The coverage depends on the ratio of the shingled spacing and the length of the substrate sheet.
  • FIG. 1 a single layer W1, a double layer W2 and a triple layer W3 of the successive substrate sheets B1, B2, B3 in relation to the position between the timing roller 3 and the belt roller 2 are shown in the imbricated flow.

  • the timing roller 4 is placed on the substrate sheet resting on the belt roller 2. Thereafter, the timing roller 3 rests at cyclical intervals during the conveying period on the imbricated flow and thereby scans its thickness profile.
  • the timing roller 3 is supported via the timing lever 4 by means of a spring 9 with respect to a holder 8 on the holder 6 and can thus perform a flexible tactile or pressing movement Z on the holder 6 with respect to the belt roller 2.
  • the rest position of the timing lever 4 in the state lifted off the belt roller 2 by the timing shaft 7 is defined by an adjustable stop 15 attached to the holder 6. In this way, when using several sensing devices, all of the timing rollers involved can be set to exactly the same sensing height relative to one another.
  • the timing lever 4 When the timing lever 4 is lowered by the movement of the timing shaft 7, the timing roller 3 is lowered as far as the belt roller 2. Depending on the number of substrate sheets lying on top of one another, the timing lever 4 moves more or less far against the force of the spring 9 against the direction of rotation Y of the timing shaft 7 on the axis 5.
  • the spring 9 holds the timing roller 3 against the belt roller 2 or the one there sheet B1 - B3 on top of it and ensures that the total thickness of the sheet layers present can be measured precisely.

  • the change in the altitude X reflects the functional cycle of the timing roller 3 and is related to a currently required product measuring range.
  • the product measuring range extends from the belt roller 2 without sheet occupancy normally with a maximum measuring path of up to three sheet thicknesses of the currently processed substrate sheets. However, it must also be able to include at least four sheet thicknesses in measuring operation, for example when double sheets pass through the measuring position.
  • a constantly updated adaptation of the required product measuring range, which correlates to a specific production cycle, is carried out automatically by means of suitable standardization steps in the measuring software.
  • the measuring device 11 has a maximum measuring range S which can be covered by the signal magnet 10.
  • zeroing is carried out automatically by recording a movement of the timing roller 3 over at least one full revolution. In this way, dimensional inaccuracies of the timing roller 3 are also recorded and can be taken into account when evaluating the measurement signals.
  • the timing roller 3 initially runs on the belt roller 2 without a substrate sheet being transported. In this way, the subsequent movements caused by the incoming substrate sheets can be identified as measured values relative to this initial value.
  • a continuous measurement profile for the substrate sheets fed via the belt roller 2 as a sheet flow and their particular position in relation to the sheet flow is obtained by continuous scanning, the product measuring range being within the measuring range S.

  • changes in the position of the signal magnet 10 are compensated for by movement tolerances on the axis 5.
  • the measurement signal can be linked to a machine angle signal for interpretation. However, the machine angle is preferably determined as a component of the overall measurement signal. Starting from a zero signal that is constantly recurring at the beginning of a measuring cycle, the measurement signal can be broken down into virtually any number of discrete values for individual measurement steps on the basis of an evaluation using an algorithm. These measured values can then be used for utilization in sheet travel monitoring.
