Definitions

  • the invention relates to a method for controlling the position of a folding machine transported bow.
  • a sheet In a folding unit of a folding machine, a sheet should be folded so that after the folding process all the edges of the sheet congruent superimposed. requirement this is that the sheet was cut absolutely right-angled, the Arc is inserted at right angles to the longitudinal axes of the folding rollers and the folding rollers have the same tensile force over their working width.
  • the folding pocket When folding in a folding pocket, it is necessary that the folding pocket is not inclined to the sheet transport direction is placed and their clearance between the pocket bars optimal is selected.
  • the sheet stop in the folder pocket must be at right angles be set to the transport direction.
  • a change in the folding result will only be made by a folding machine operator then recognized when the quality of the finished folded sheet is continuously checked. The operator then has to recognize by means of the folded product, at which point the folding machine a correction must be made so that the folding quality is optimal again. This is very elaborate and requires a very large experience of the operator.
  • the invention is based on the object with structurally simple means a method for controlling the position of a sheet transported in a folding machine which allows an operator to be the source of error in the folding of a Quickly recognize bow and take the appropriate measures to correct.
  • the operator of the folding machine by the error signal of the processor device on the misalignment of the sheet made aware.
  • the operator immediately recognizes where in a folding machine the error first occurred. He can then take the appropriate action take to fix the misplacement of the bow.
  • the processor device can issue a command to stop the folding machine.
  • the detection device is in a preferred embodiment of a Light curtain made an electric depending on the cover by the bow Sends signal as a measured value to the processor device.
  • a Light curtain is, for example, the photo sensor with analog output FAV30-01 of SensoPart.
  • the electrical signal may be a voltage value, e.g. from 0 to 10V, a Current value, e.g. from 0 to 20mA, a serial data interface a parallel Interface or the like.
  • the capture and evaluation can also be done via an image processing system done with camera, processor device and appropriate software.
  • the reference curve is preferably determined by running a calibration sheet, the folded optimally after passing through the folding machine.
  • the folding machine shown in Fig. 1 comprises a first folding unit 23 with two folding rollers 24, 26 and a first folding unit 23 downstream second folding unit 29th with folding rollers 28, 30 on.
  • the first folding unit 23 is a first inclined roller table 16 upstream, which has in a known manner an alignment ruler 20, located in Transport direction TR1 of the sheet 36 extends. Ideally, the bow will be 36 brought by the first inclined roller table 16 to bear against the alignment ruler 20 and then guided in the transport direction TR1 between the folding rollers 24, 26 and folded by these.
  • the transport direction TR2 perpendicular to the transport direction TR1 of the first inclined roller table 16 runs. Due to the oblique rollers of the sheet 39 is for concern to a Alignment ruler 22 brought and then between the folding rollers 28, 30 of the second Folder 29 guided and folded again.
  • a light curtain 32 arranged as a detection device, whose longitudinal direction in the right Angle to the longitudinal direction of the alignment ruler 20 extends.
  • the sheet 36 should already be on the alignment ruler 20 abuts, then in the transport direction TR1 between the folding rollers 24, 26 to be introduced.
  • the light curtain 32 is arranged to overlie the alignment ruler 20 away curved edge 37 extends in the direction of the alignment ruler 20, to capture the sheet edge 37 can.
  • the light curtain 32 gives a reading to a processor device (not shown).
  • the light curtain is for example a photosensor with analog output FAV30-01 from the company SensoPart. This Photosensor is dependent on the cover through the sheet 37 a voltage from 0 to 10V to the processor device on.
  • a similar light curtain 34 is arranged in front of the second folding unit 29.
  • Fig. 2 shows schematically a folding pocket 40 having a plurality of pockets forming a pocket Pocket bars 42 and the way one of the folding pocket 48 incoming Bow limiting stop 44. Shortly after the pocket inlet is parallel arranged to the stop 44 in light curtain 46, which extends beyond the in Fig. 2 extends right edge 49 of an arc addition. As indicated by the double arrow TR is indicated, the sheet 48 is inserted until it hits the stop 44. Subsequently, the sheet 48 is again conveyed out of the folding pocket 40 addition.
  • Fig. 3 shows a U (voltage) -S (path) reference curve RK of a Calibration sheet, which is determined by the processor device based on the measured values which was detected by the light scanner 32 during the passage of a calibration sheet.
  • the voltage U is from the light curtain to the processor device passed.
  • the path S is via a rotary encoder at the corresponding Folder determined.
  • This rotary encoder is with the sheet transport system firmly connected.
  • Each pulse on the rotary encoder corresponds to one certain way of the sheet transport system. From the number of pulses Therefore, the processor device can the Bogenweg S and thus the U-S curve determine.
  • FIG. 4 shows a measurement curve MK1 of an obliquely in the region of the light curtain 32 continuous arc 36 shown.
  • the measurement curve MK1 shows that the arc edge 37 at the inlet through the light curtain 32 closer to the alignment ruler 20th is located as the sheet edge 37 of the calibration sheet.
  • At the end of the run of the bow 36 corresponds to the distance of the sheet edge 37 substantially the distance the bow edge of the calibration bow.
  • the measured curve MK2 shown in FIG. 5 shows that the sheet running direction of the sheet 36 is parallel to the sheet running direction of the calibration sheet. However, covers the arc 36 continues the light curtain 32, as the calibration sheet, so that of the Light curtain 32, a higher voltage is delivered.
  • the measurement curve MK2 corresponding arc 36 is thus at a distance from the alignment ruler 20th
  • FIG. 6 shows a measurement curve MK3 of a sheet 36 which is exactly along the alignment ruler 20 is transported and whose width corresponds to the width of the calibration sheet. However, the leading edge of the incoming sheet 36 runs later in time in the light curtain 32 as that of the calibration sheet.
  • a measurement curve MK1, MK2 or MK3 determined by the processor device If it is, it outputs an error signal indicating that the sheet 36 does not correspond to the Eichbogen is transported accordingly. After output of the error signal can then taking into account the differences of the measured curves MK1, MK2 and MK3 to the reference curve RK by an operator or possibly automatically the appropriate measures are taken.
  • the second embodiment of the folding machine 50 shown in FIG. 7 differs extending from the folding machine shown in Fig. 1 in that the folding roller pairs 23, 29 each a pair of knife shafts 52 and 54 is arranged downstream, through the perforations or creasing in a folded by the Falzwalzencrue 23, 29 bow be formed, which weaken the sheets along a fold line.
  • Correcting slate perforation lines is usually done by pulling one the pair of knife shafts 52 arranged in the folding unit 12 curved switch (not shown) performed on the leading page. Pulling becomes a path extension enforced when passing through the curved switch and thus the lead compensated.
  • the use of the light curtain 58 behind the pair of knife shafts 52 allows monitoring of the directional stability of the expiring arc side edge 62 and thus the perforation line generated in the pair of knife shafts 52.
  • Any deviation of a determined measuring curve from a reference curve can be the Operators are signaled by an error signal of the processor device, so that the corresponding bow diverter can be pulled.
