  • roller-based die-cutting machines used for the die-cutting of adhesive labels is based on a sheet in which a base layer of waxed, silicone or similar paper participates, on which An adhesive sheet itself is provided, intended to be die-cut to obtain a plurality of smaller adhesive labels.
  • These labels must be duly stamped without the blades damaging the base sheet on which they rest, in order to ensure that the sheet has a single-piece appearance at the exit of the machine, that is, the labels can be independent one by one from a single one common lamina.
  • the problem is that these sheets can have different thicknesses depending on the type of paper used, so the distance between the base cylinder and the die carrier cylinder must be adjusted so that the die blades do not damage the base sheet, a maneuver that to date it is carried out by hand, by means of the manual micrometers associated to the axis of the die-bearing cylinder or to the axis of the base cylinder.

Abstract

Selon l'invention, un dispositif permet de relier les extrémités de l'axe (9) de rotation du cylindre porteur du poinçon de coupe à une came excentrique (10) au moyen de roulements ou de paliers (11), de manière que la rotation de la came, par un bras (12) associé à un arc d'engrenage (13) qui est actionné par une vis sans fin (14) commandée par un moteur (15) à impulsions, a pour effet que l'excentricité entre des axes lors de la rotation de la came provoque le déplacement micrométrique vertical de l'axe de rotation du cylindre porteur du poinçon, dans un ordre qui permet à celui-ci d'être réglé parfaitement à différentes grosseurs du papier de sorte que les étiquettes sortent parfaitement perforées sans endommager la couche de base sur laquelle elles se trouvent. Ce dispositif peut être placé de manière indistincte dans le cylindre (5) porteur du poinçon (4) ou le cylindre de base (4) dans les deux, avec la caractéristique ajoutée de bien utiliser le système pour amortir les poinçons qui vont s'user à force d'utilisation, les rapprochant pour une coupe optimale.
