Definitions

  • the present invention relates to an apparatus and a method for checking printed sheets which must be subjected to subsequent phases of production, such as die-cutting, embossing, painting, gluing and the like.
  • An example of application of the present invention is the manufacture of cardboard boxes (or made from other similar material) from a flat sheet which is printed and subsequently die-cut. The sheet thus obtained is then cut to give a plurality of portions comprising the various elements of the box, e.g. the walls, the fixing flaps and similar.
  • an initial check on the production method is carried out by examining a pre-determined sample of sheets coming out of the printing machine. For instance, the multiple-colour images require the subsequent printing of the prints corresponding to each colour. There may be errors of alignment between the prints of the various colours, for instance an unwanted overlap of the colours, that could be caused by the tolerances inherent in the printing machines or by deformations of the sheet subjected to the printing of the preceding imprints.
  • each colour makes a series of thin crossed lines in the corners of the printed sheet, in such a way as to superimpose the subsequently printed lines from each imprint.
  • the visual examination of each "cross" in the corner of the sheet reveals whether the printing of the colours, and particularly their alignment, is correct.
  • a similar check could not be done on all the sheets printed, but only on those in the sample.
  • the sampling check allows slowdowns in production to be avoided, but doesn't ensure the same quality for all the printed sheets or the presence of all the imprints of the printed colours on all the sheets.
  • EP-A-453974 discloses an apparatus according to the preamble of claim 1.
  • This apparatus has only one device for detecting two groups of signs printed on the same side of the sheet. The correct alignment of the sheet with respect to the subsequent die-cutting station is consequently detected taking into account the signs printed only on one side of the sheet.
  • a first group of four signs is detected when the sheet is still moving before reaching the die-cutting station, while the second group of signs, consisting of only one sign, is detected when the sheet is stopped before being introduced into the die-cutting station.
  • One object of the present invention is to provide an apparatus that allows precise and reliable checking of the printed sheets, assuring in particular a check on the presence of each imprint on all the sheets.
  • Another object of the present invention is that of providing an apparatus that enables, without exception, a check on all the printed sheets subjected to subsequent phases of production without slowing down the normal rate of production.
  • a further object of the present invention is to provide an apparatus that enables the printed sheets to be checked between the subsequent phases of production.
  • the apparatus comprises means for applying an identification element to a sheet coming out of a machine that performs a phase of production subsequent to the printing. For instance, in the case in which any defect is detected on the sheet, it is possible to apply a label to the same sheet, for instance in a projecting position, to identify it easily and separate it from the rest of the sheets.
  • the means of optical detection are mounted above a plane of transit of the sheets along the machine that performs a subsequent phase of production, in correspondence with a position in which the sheet is stopped before being inserted into the production station.
  • the means of optical detection are mounted in a sliding manner on guides parallel to the plane of transit of the sheets, and they comprise at least one fixing device to allow correct positioning along the guides.
  • the means of optical detection further comprise at least one device of regulation of the focal distance with respect to the plane of transit to allow the correct focusing of the images on the sheets in each case.
  • Such means of optical detection employs preferably two charge coupled type image detectors (CCD), for each of which a source of ultraviolet light is provided. In this way even images printed with clear colours can be detected with high precision.
  • CCD charge coupled type image detectors
  • the method advantageously comprises the application of an identification element to a sheet coming out of the machine in the case where the sheet is found to have an image in which at least one of the reference signs is misplaced with respect to the pre-set position by more than a pre-set distance.
  • the reference signs are grouped in two printed groups near to the longitudinal opposite edges of each sheet, in position substantially central with regard to the total length of the edges. That allows an effective determination of whether the position of the imprint of each colour, independently of the others, is within a pre-set tolerance for that particular colour.
  • Each of the groups comprises at least one reference sign for each of the printed colours on the sheet, in order to verify the presence of all the colours.
  • Figures 1 and 2 show a die-cutting machine 1 comprising a store 2 in which it is stored a stack 3 of printed sheets that must be die-cut. Downstream of the store 2 a feeding device 4 is arranged, provided with known means (not shown) of withdrawing the sheets 5, 5' from the stack 3 and sending them along a plane of transit 6 to the subsequent die-cutting station 7. The sheets 5" leaving the die-cutting station 7 are transferred on a stack 8 placed in a collection bin 9 for die-cut sheets.
  • the apparatus comprises a pair of image detectors 10, for instance of the charge coupled type, that are mounted in a sliding manner on respective guides 11 and that could be fixed in position with suitable means of known type.
  • the guides 11 are substantially parallel to the plane of transit 6 of the sheets 5, 5' that flow between the store 2 and the die-cutting station 7.
  • a source of ultraviolet radiation (not shown) is linked to each of the image detectors 10 to allow an effective reading also of the clearer colours.
  • the image detectors 10 comprise preferably at least one device of regulation of the focal distance with respect to the plane of transit 6 of the sheets 5 and 5'.
  • a synchronizing device 12 that allows to generate an enabling signal of the reading at the moment in which a sheet 5' is in position of reading under the image detectors 10.
  • the synchronizing device 12 could be realized for instance with a proximity sensor arranged in a suitable position, or also with a disk encoder mounted on a rotating shaft of the die-cutting machine 1. In any case, the synchronizing device 12 must be predisposed so as to generate an electric enabling signal for the image detectors when a sheet 5' transits in the pre-set position.
  • the signal generated from the synchronizing device 12 and the signals deriving from the image detectors 10 are addressed to a processing device 14 through an interface unit 13.
  • a printed and die-cut sheet 5" Downstream of the die-cutting station 7, there are preferably provided means for applying an element of identification on a sheet 5" that comes out of the die-cutting machine 1. Indeed, if a printed and die-cut sheet 5" is considered not in conformity with the requirements of production, it can be identified, for instance, by means of a label 16 ( Figure 2) applied on an edge or an angle of the sheet in order to allow the immediate identification also after the end of the complete cycle of production.
  • the method according to the invention involves, during the usual operations of printing of the images on the sheets, also the printing of at least two groups of reference signs, indicated with 20a and 20b in Figure 2, in correspondence of the opposite edges of each sheet 5.
  • each group of signs 20a and 20b comprises a reference sign 21a-23a, 21b-23b for each of the printed colours on the sheet.
  • the printed sheets 5 thus predisposed are therefore fed to the die-cutting machine 1 that withdraws them from the stack 2 in the store 3 and addresses them, with intermittent movement, along the plane of transit 6, to the die-cutting station 7.
  • the device 12 When a sheet 5', during his intermittent movement, is stopped temporarily before entering the die-cutting station 7, that is in the position in which the groups of signs 20a and 20b are placed below the image detectors 10, the device 12 generates a synchronized signal that enable the reading of the detectors 10.
  • the images of the reference signs 21a-23a, 21b-23b are thus detected and transmitted under form of electric signals to the processing unit 14 through an interface unit 13 that can also be housed inside of the processing unit itself.
  • the processing unit for instance consisting of a central unit, a monitor 25, a keyboard and/or a mouse, is equipped with a program that allows to receive the images transmitted from the image detectors 10 and display them on the monitor 25.
  • FIG. 3 An example of the images displayed on the monitor 25 is shown in Figure 3, in which the views of the reference signs 21a-23a and 21b-23b are represented. Each of these signs is surrounded by a small circle 26 identifying the area of the maximum accepted deviation with respect to a pre-set position for each reference sign.
  • the program allows to determine the detected deviation for each sign with respect to the position of correct alignment of the sheet 5' in the die-cutting station 7.
  • the deviations of the position of each sign with respect to the expected position can be detected in any case, thus allowing to display and/or store in a memory at least the relevant data of the deviations detected during the operation of the die-cutting machine 1.
  • the computer is also assigned for the control of the device 15 that allows to apply an identification element 16 on a sheet coming out of the die-cutting station 7, when it is detected an image in which at least one of said signs of this sheet is misplaced with respect to the expected position for a distance larger than a pre-set distance.
  • the positions and dimensions of the circles 26 are determined during the starting phase of the die-cutting machine 1. At first, a pre-set number of correctly printed sheets is selected, for instance from five to twenty sheets on the base of the required precision of working.
  • These sheets are fed to the die-cutting machine in such a manner to allow the regulation of the position of the image detectors 10 along the respective guides 11, and the regulation of the focal distance of the detectors 10 with respect to a sheet 5, 5' disposed on the plane of transit 6. It is therefore also detected the position of the reference signs 21a-23a, 21b-23b with respect to the shot of the detectors, that is with respect to the system of reference integral with the die-cutting machine, to allow the statistic calculus of the position of the reference signs on the sheets 5'. They are therefore calculated the dimensions of the maximum deviation of each reference sign on the base of the desired working tolerances.
  • the program is able to classify the type of each anomaly detected on the printed sheet to allow the identification of the machine that provoked this anomaly.
  • the apparatus according to the invention can be applied between each pair of machines carrying out subsequent productions to the printing. In this case, it is again possible to easily identify the machine that has provoked possible anomalies of production of the sheet.
  • the reference signs 21a-23a, 21b-23b have identical dimensions and are spaced each for a same length with respect to an adjacent sign, as well as the circles 26. However, on the base of the alignment between the different colours or on the base of the different tolerances of production, the positions of the reference signs 21a-23a, 21b-23b and the dimensions of the relative circles 26 within which they must be contained, can of course be different.
