Definitions

  • the present invention relates to a device for trimming and automatic cutting of a multiple or single images, obtained in particular by digital rendering on paper or other graphic or photographic supports wound in rolls or in the form of single sheets, especially of large size.
  • a preferred embodiment of the present invention provides for two angular motors placed at the side ends of the cutting unit and synchronized by the microprocessor such as to simulate the central pivoting of the cutting blades in spite of their lateral guide.
  • Figure 1 shows a diagrammatic top view of a trimming and cutting device according to the present invention with the substrate of images correctly fed and the cutting unit being aligned with the feeding rollers;
  • Figures 2 and 3 show the same device of figure 1 with the substrate of images inserted with two opposite angles with respect to the feed, at a right angle with respect to the cutting unit, before intervention of the foreseen means of automatic correction.
  • a device 1 for the automatic trimming and cutting of images 10a, 10b, 10c printed in a traditional way or obtained by digital restituting systems on a substrate 10 formed e.g. as a continuos paper reel but which could instead be formed of single sheets.
  • the successive images 10a, 10b, 10c are separate by marks or boundary lines M which can be detected optically by means of a pair of sensors 4, 4' along an ideal reading line that is perfectly transverse to the feed direction as indicated by the arrow F.
  • the feed of substrate 10 is driven by at least a pair of rollers 2, of which only the one above the substrate 10 is visible.
  • the length of the feeding rollers 2, useful to hold the substrate 10 is reduced with respect to the total width of the mobile cutting device 7 and also to the width A of the working table of the device. They are in a central position with respect to the substrate 10 and are driven by a motor 3.
  • differential length gauges 6, 6' or “encoders” having a mutual distance B which is larger than the length of rollers 2 and shorter than said width A.
  • the optical sensors 4, 4' detect an angle zero and the two differential length meters 6, 6' detect a likely identical feed of the substrate 10 starting from the moment at which the mark M is detected by the optical sensor 4, 4' until the end of the feed movement or "offset” being controlled by a microprocessor, corresponding to the distance between the reading point or line as defined by the optical sensors 4, 4' and the working line of the cutting unit 7. If the feed is identically detected by the two "encoders" 6, 6', it means that there are no angular errors to be taken into account for the cutting and this will be accomplished under control of motor 9, along a line perfectly parallel to the separation mark M.
  • the two encoders 6, 6' detect different "offset" lengths during the shift automatically controlled by the microprocessor, this means that the nip of the rollers 2, which is of limited extension in the central zone and due in particular to the weight itself of the paper substrate, causes a skidding. In this way the angle shown by the mark M against the cutting units 7 after the "offset" feed will be modified and to correct the same the device of the present invention will be useful. In fact, the angular error will correspond to the feed difference as detected by the two encoders 6, 6' at the side of rollers 2.
  • the relevant differential data are supplied to the microprocessor which causes its algebraic sum with the possible angle of entering error, whereby the control pulse to the two motors 5, 5' can correct the cutting position to the same extent as the error given by the skidding of material.
  • the drive of the two motors 5, 5', which are placed at the end sides of the cutting unit 7, is synchronized by the microprocessor such as to simulate, with two lateral guides, a central pivoting of the cutting unit itself.

Abstract

Cette invention concerne un dispositif de rognage et de découpage automatique d'images simples ou multiples produites par exemple numériquement sur papier ou autres substrats graphiques et photographiques, sous forme de rouleaux ou de feuilles uniques (10), en particulier de grande taille. Les problèmes posés par des dispositifs connus de type en ce qui concerne l'alimentation de rouleaux (2) avec une longueur correspondant au substrat ont pour effet de ralentir la production compte tenu du soin extrême qu'il faut apporter lors de l'introduction simultanée de feuilles parallèle de grande taille. Il est possible de résoudre ces problèmes en utilisant des rouleaux de longueur réduite et en ajoutant une marge d'erreur uniquement dans le mouvement d'avance du substrat, erreur qui peut être reprise au moyen de capteurs optiques (4, 4') qui détectent le repère de séparation (M) entre les images (10a, 10b, .....) ainsi que son angle par rapport à la ligne de coupe (7), et au moyen d'une paire de dispositifs de mesure des écarts de longueur (6).
