Definitions

  • the invention relates to a method according to the preamble of claim 1 and to an automatic cutting machine for performing the method.
  • notes of sheet with a certain number of benefits that is to say with a certain number of security impressions arranged in a matrix
  • these sheets are stacked step by step in strip layers and then the strip layers in bundles of notes cut, whereby the individual notes of the bundle receive their finished format.
  • the feed lengths for the step-by-step feed of the sheet stacks and the strip positions are fixed in each case based on a feed program that has been set once, depending on the size of the banknotes or the desired note format.
  • the resulting cut-out notes are of course all the same size. This uniform size of notes is advantageous for the automatic further processing, sorting and packaging of the bundles of notes.
  • the security print includes direct gravure printing, in particular a steel engraving print, in which the printing plates are subjected to a very high contact pressure and experience a gradual expansion under the action of these forces during operation, that is to say become increasingly longer and also wider, this widening becoming greater along the pressure plate in the direction opposite to the direction of rotation of the plate cylinder.
  • the schematic shape of such a deformed, approximately trapezoidal printing plate corresponds to the outline 11 'in FIG. 2, which will be explained in more detail later.
  • the length and widening of the printing plate change the size and position of the prints, so that the automatic stacking of sheets is done with constant feed lengths cut notes of value arise, in which the printed image moves more and more from its centered position with increasing number of prints and therefore the difference in the widths of the margins becomes more and more striking.
  • the invention has for its object to provide a method which, despite a printing plate deformation occurring in the course of operation, always allows receipts to be obtained when cutting the stack of sheets, which have at least approximately centered printed images with respect to the value edges.
  • the A e may be performed in the simplest case by hand due to an experience of the program that was empirically for the relevant printing plates, optionally also positioned and theoretically.
  • the readjustments to be made to the original feed program can also be made on the basis of regular inspection and measurement of the printing plate, for example after every 50,000 or 100,000 prints.
  • a change in length of the individual feeds can be carried out particularly precisely and easily with commercially available feed devices, which are known as linear amplifiers.
  • These linear amplifiers have a hydraulic cylinder-piston system, whereby the metered pressure medium supply of the hydraulic cylinder takes place with the aid of a stepper motor which briefly opens the pressure medium inlet valve with each revolution; as a result, with one revolution of the stepper motor, a precisely metered, small amount of pressure medium is supplied to the cylinder such that the piston carries out a feed of, for example, 0.1 mm.
  • Such a hydraulically controlled feed also works with a sufficiently short response time.
  • a preferred embodiment of the method according to the invention is to apply printing marks on the printing plate which define the later cutting lines and inevitably take part in the deformations of the printing plate, and to control the feed devices by reading devices which read the markings made during the printing process. These markings are printed on the edges of the sheets and, if appropriate, on the areas lying between the printed images, which are cut off as waste strips during later sheet edge trimming or later intermediate cuts. In this way, the cutting machine can be automatically controlled as a function of the positions of these print markings in such a way that notes of value are always cut whose print image is centered correctly or at least much more precisely than before.
  • the deformation effect of the base plate is more important in the longitudinal direction than in the transverse direction, so that under certain circumstances the feed lengths only need to be changed for the strip cuts made parallel to the gripper edge and centering correction can be dispensed with for the bundle cuts.
  • FIG. 1 shows schematically those processing stations at which process steps take place according to the invention. It is assumed that the coupons have already been printed on both sides in offset printing and also on one side in steel engraving. The last printing process for the note sheets prepared in this way is that the other sheet side is also printed with an engraved print image.
  • the engraving printing unit 20 provided for this purpose is indicated schematically in FIG. 1.
  • the individual, fully printed sheets 10 each have 24 security prints or so-called individual benefits, which are arranged in a matrix in six rows, each with four security prints.
  • FIG. 2 shows an enlarged sheet 10 of this type with its six rows of banknotes 1 to 6; the banknotes later cut to format are designated by 12 and the actual banknote impressions surrounded by an unprinted border are designated by 13.
  • the individual sheets are pulled by sheet grippers which hold the front sheet edge as they pass through the printing units.
  • This sheet edge lying at the front when it passes through the printing units in the transport direction F 0 is the so-called gripper edge 14 (FIGS. 1 and 2), and the value rows 1 to 6 are oriented parallel to this gripper edge 14, that is to say transversely to the direction of the sheet passing through the printing units .
  • the remaining three sheet edges are labeled 15, 16 and 17.
  • the finished printed sheets 10 of the stack S2 are usually subjected to a visual quality control, in which sheets are discarded with misprints, and are then input from an input stack S3 into a numbering machine 21 for numbering the individual uses and placed at the output thereof on an output stack S4.
  • a sheet stack S5 is first transported in the direction of the arrow along a transport path 22 to the entrance of a cutting path 24 and brought into a defined starting position P1, in which all sheets 10 of the stack are aligned with their gripper edges 14 at a stop 23.
  • the gripper edges 14 form the trailing edge of the sheet and thus the reference edge of the sheet stack which is decisive for the strip cut, on which finger-like slider is known in the known manner an automatic feed device 26 to feed the stacks.
  • the strip cutting device 27 which is designed as a cross cutting device, first at the front of the stack the edge trim of the front edge 16 of the sheet 10 ( Figure 2), then the stack is divided step by step into each of its six stripe layers 18, which correspond to the six value rows 1 to 6, and finally on the back of the last stripe layer the rear Edge trimming of the gripper edge 14 is carried out.
  • the waste paper from the edge trimmings falls through a waste flap.
  • a banding station 29 with a number of individual banding devices corresponding to the number of blanks per strip, in the example considered four banding devices that are operated simultaneously in each work step, in such a way that each layer of strips 18 is simultaneously connected to the four note or Benefit positions with a pre-glued band 129 is surrounded.
  • the finished banded strip layers 18 are first removed from the banding station 29 in the direction of the arrow in the longitudinal direction of the strip and then moved along the transport path 35, transversely to the longitudinal direction of the strip, by means of a feed device 30 to the entrance of the cutting path 36, on which an automatic bundle cutting unit 33 designed as a cross cutting unit is installed.
  • a feed device 30 to the entrance of the cutting path 36, on which an automatic bundle cutting unit 33 designed as a cross cutting unit is installed.
  • all six strip layers 18 belonging to one and the same sheet stack S5 are collected in a defined starting position P2, in which the edges trimmed in the longitudinal cutting device 25 are aligned by abutment against a stop which is formed by the slide system 31 of the feed direction 32 .
  • the feed device 32 While in previously known installations there was a single template common to all strip layers is provided with a slide, the feed device 32 according to the invention, as will be explained later, consists of a number of individual feed devices corresponding to the number of strip layers 18 per stack with sliders individually moving the strip layers. All six strip layers 18 belonging to a sheet stack, which, as indicated in FIG. 1, are arranged next to one another at a small distance, are then moved together by means of the feed device 32 in the direction of the arrow F2 to the bundle cutter 33, wherein they are guided in grooves. In the bundle cutter 33, the front edge of all the strip layers 18 corresponding to the sheet side edge 17 (FIG.
  • the banded bundles 19 cut into format are advanced to a transport path 37 and arrive at further processing stations which are not of interest here, in which bundle packages with consecutively numbered notes of a certain one Series are formed and then these bundle packages are banded and packed.
  • This further processing is the subject of, for example, the Swiss patent specification CH 577 426 and the American patent specifications US 3 939 621 and 4 045 944 by the same applicant.
  • the originally set constant feeds D, a, E o and b are used.
  • the outline 11 of the overall printing image (including the later value edges) shown in FIG. 2 is, of course, exactly rectangular, corresponding to the exact original geometry and arrangement of the engraving pits of the printing plates, and the security prints also shown rectangular in FIG. 2 13 are all undistorted and of the same size and, after the sheet 10 has been cut along the dashed lines in value notes 12 with the same axb format, are always centered with respect to the unprinted value border.
  • the printing plates now expand under the action of the contact pressure which is exerted by the printing cylinder during each printing process.
  • This deformation is particularly strong in the case of an engraving pressure plate, since a particularly high pressure has to be used in steel engraving printing.
  • the lengthening and widening takes place in a non-linear manner, so that the printing surface takes on an approximately trapezoidal shape, the rear printing plate edge as seen in the direction of rotation of the plate cylinder forming the base side of the trapezoid.
  • the outline 11 ' which delimits the area of the overall printed image of all the security impressions of a sheet 10 and is shown in dash-dotted lines in FIG. 2, and each individual security impression are distorted approximately in a trapezoidal manner.
  • the total print image in direction F1 is extended by the amount d compared to its original dimension, which was 6a.
  • a sheet 10 the print image of which is distorted and has the outline 11 ', is shown in FIG.
  • those lines are drawn in dashed lines in FIG. 3 which would have to form the cutting lines in the later strip and bundle cut, so that despite the distortion in all the manufactured notes, the security impressions (not shown in FIG. 3) are at least approximately in the mirror, i.e. are centered in relation to the blank value border.
  • the dimensions of the individual blanks oriented in the direction of F2, i.e. parallel to the gripper edge 14 initially decrease along each of the value rows 1 to 6, starting with a value which is enlarged compared to the original dimension b, and then increasing again and are also gradually increased from value series to value series, viewed in the direction of Fl.
  • the individual benefits located at the ends of the value row 6 have a dimension b + y enlarged by the amount y, while the two middle individual benefits are only extended to b + 0.5.
  • the two individual uses at the ends have the dimension b + 2y and the two middle ones have the dimension b + y.
  • the two individual uses at the ends have the dimension b + 3y and the two middle ones have the dimension b + 1.5y.
  • the outer individual uses have the dimensions b + 4y, b + 5y and b + 6y and the middle ones the dimensions b + 2y, b + 2,5y and b + 3y.
  • the values x and y after 100,000 prints can be, for example, approximately 0.05 mm each, so that the extension d of the total printed image of a sheet (FIG. 1) is approximately 1 mm.
  • the printed image 13 of the banknotes 12 is practically still centered within the row of banknotes 6 within the unprinted banknotes border, but all other banknotes indicate this a more or less shifted print image from its central position, whereby these centering errors are greatest for the value notes of the value series 1 and of course become stronger and more conspicuous with an increasing number of prints.
  • the correction for the strip cut should first be considered.
  • pressure markings are provided on the engraving printing plate, which define the later cutting lines and inevitably change their position as the printing plate expands.
  • these markings are also printed on one side edge 17 of each sheet and, in the example considered (FIGS. 2 and 3), consist of line-shaped markings m which are assigned to the cutting line parallel to the gripper edge 14. These marks are immediately before the sheet enters stack in the strip cutter 27 read by a reader 28 ( Figure 1), which brings the sheet stacks to a standstill in the intended cutting position.
  • the distance of the reading device 28 from the knife of the strip cutting unit 27 and the positions of the markings m relative to the cutting lines assigned to them are selected such that after the feed device 26 has been switched off when the reading device 28 is activated, a sheet stack arises due to its inertia and the inertia of the Feed mechanism just moved into the desired cutting position and comes to a standstill there.
  • This braking distance or run-out distance of a stack is a defined and exactly reproducible size for the same stack.
  • the following markings m precisely control the sequence of the successively smaller feed steps, in the example according to FIG. 3 the feed steps a + 6x, a + 5x, etc. to a + x.
  • the easy-to-implement markings to be printed and their automatic reading by a reading device 28 controlling the feed device 25 therefore permit constant exact control of the feed lengths when cutting strips as a function of the constantly increasing pressure plate deformation.
  • double markings which, as indicated in FIG. 3, consist of two line-shaped markings or mouth m located at a small distance from one another.
  • the arrangement is then such that when the first mark m s is read, the normal feed speed of the sheet stacks is reduced to a creeping movement and the feed device is only switched off when the second mark m is read.
  • the preceding braking of the sheet stacks before they are stopped in this way increases the run-in accuracy into the cutting position and is expedient if the sheet stacks are pushed in the usual manner, as described, by means of sliders which only abut the rear edge of the stack.
  • this side edge trimming is not always carried out exactly at a right angle to the gripper edge 14 (FIG. 1), but rather along the line delimiting the side edge 15 the trapezoidal outline 11 'of the overall printed image; this cutting line includes the angle ⁇ with the gripper edge 14 (FIG. 3), which becomes greater than 90 ° with the beginning of the distortion and increases with increasing pressure plate expansion.
  • the longitudinal cutting device 25 or its knife can be rotated about a vertical axis in such a way that the cutting angle ⁇ relative to the gripper edge 14, starting from an originally right angle, can be made ever larger during operation.
  • the slides 311 to 316 of the feed devices 321 to 326 are also set more and more obliquely in the course of operation, so that they are always oriented parallel to the rear edge of the strip layers 18 and thus lie snugly against them in order to ensure a well-defined feed.
  • the slides 311 to 316 can be pivoted about vertical axes within a sufficient angle.
  • this cutting angle ⁇ of the slitter 25 can be controlled automatically; at this point assumed that the cutting angle is changed as a function of the increasing distortion, as explained, which in the simplest case can be carried out by hand in such a way that after the passage of, for example, 50,000 to 100,000 sheets in each case, corresponding to 500 to 1 ' 000 stacks of 100 sheets each, based on a visual inspection and measurement of the printed images or the stretched printing plate.
  • This can be a local pattern, a specific color range or a striking contrast, preferably the contrast between the light, unprinted value border and a dark area of the value print.
  • a characteristic point in particular a sufficient contrast at the limit of the printed value, can be found practically on all printed values and can be used as a natural marking selectively recognizable by a reading device, which defines the adjacent cutting line.

Starting from the aligned starting position P2, the six strip layers 18 are advanced together, which are of different lengths on their rear edges due to the somewhat oblique edge trim, as illustrated in FIG. 4.
  • the reader 341 responds first to the first contrast point of the strip position corresponding to the bank note row 1, that is to say to the front boundary of the first security print image, and therefore switches off the feed device 321.
  • the arrangement is such that the strip position then comes to a standstill after a total feed length E1 in the first desired cutting position, in which the front edge of the strip layer is trimmed.

  • the distortion effects produced by the printing plate stretching in the transverse direction are less disturbing than those in the longitudinal direction (direction Fo), because namely the widening in the transverse direction is symmetrical on both sides and therefore the security impressions in the central region of the sheets are only relatively slightly after the one and be shifted towards the other side and the security prints lying on the outside experience a shift which only corresponds to approximately half of the overall widening of the overall printed image 11 '.
  • the distortion effects add up in the individual bank note rows 6 to 1 of a sheet in the longitudinal direction, that is to say in the direction F1, as the example according to FIGS. 2 and 3 illustrates. For this reason, it may be sufficient to apply the feedrate correction described only for strip cutting and, as usual, to work with constant feed rates for bundle cutting.
  • the correction options described above for the strip cut and for the bundle cut can also be combined in any way, for example in such a way that the feed control takes place fully automatically during the strip cut, while the feed program for the bundle cut is changed by hand as required.
  • the accuracy of the centering of the security prints within their border not only depends on the printing plate stretching, but is subject to more or less large tolerances, which essentially depend on differences in the format of the note sheets, on the pressing and stretching of the paper during printing and from its moisture content and inaccuracies when cutting. It would therefore be useless to introduce feed corrections that are more precise than the tolerances mentioned, to which the centering of the security prints is subject for other reasons.
  • FIG. 5 shows a bill of value 110 with 16 individual bills 112 which are arranged in four rows of bills 101 to 104 of four individual bills each. It is assumed that the engraving printing plate, which has printed this sheet, has undergone a noticeable stretching, as in the example according to FIGS. 2 and 3, so that the outline 111 ′ of the total printed image of all the security prints 113 is again distorted in a trapezoidal manner.
  • print markings m are again provided on the side edge 117, which are read by the reading device 28 for the purpose of feed control during the strip cut, and on the other hand print marks Markings n, which are printed on the intermediate strip between adjacent individual uses of each bank note series and are read by the readers 341 to 344 (FIG. 6) for the purpose of feed control during the bundle cut of the individual strip layers 118.

  • the front edge 116 is first cut off in the strip cutter 27, the feed into this cutting position being controlled by the reading device 28 by reading the first pressure marking m.
  • the length a of the following feed step into the cutting position required for the first strip cut is pre-programmed.
  • the feed into the following sectional position, in which the intermediate strip Z1 is cut off, is in turn controlled by the reading device 28 by reading the second print mark m. This is followed by a feed step of length a, and immediately.
  • the feed device 32 for the four strip layers (118) belonging to a stack again comprises feed devices 321 to 324 individually assigned to these strip layers with their slides 311 to 314.
  • each of the feed devices 321 to 324 carries out a programmed feed step Length b, whereupon the foremost bundles of notes of each strip layer are cut off.
  • the next feed is in turn controlled by the reading devices, individually for each strip position, when reading the respective marking n on the intermediate strips Z11, Z21, Z31 and Z41, whereupon these strip layers are cut off together. This cut is followed by a programmed feed step of length b, etc.
  • the described feed control when working with intermediate cuts can also be carried out either according to a prepared program that changes as a function of the printing plate expansion or by hand, as is the case for the example according to FIGS. 2 to 4 has been described.
  • feed control by reading devices it is also possible, without special printing markings m and n, to use characteristic points of the individual use that are selectively recognizable by the reading devices as natural markings, in particular the contrast at the boundary of the security print, as explained earlier.
  • the method according to the invention can also be applied to sheets of notes in which the strip cuts are made with individual cuts, whereas the bundle cuts are made with intermediate cuts. In this case, it is possible to work with pressure markings m for the strip cut and with pressure markings n for the bundle cuts, it being ensured that the dimension b of the note format remains constant.
  • both opposite side edges of the sheet stack can be trimmed simultaneously on the cutting section 24 before the strip cuts are carried out.
  • the strip layers belonging to a sheet stack can be divided into bundles of notes one after the other in time, the feed steps being successively changed individually for each strip layer.
