Definitions

  • the present invention relates to a device which has been especially conceived to allow fine adjustment of the positioning between the cutting cylinder and the base cylinder for label work and the like, when an extremely accurate precision of cutting depth is required, in machines based on rotary cylinders intended for that purpose.
  • a prior art machine of the general type is shown in WO 2014/135265 A1 .
  • the object of the invention is to provide a mechanism that allows the automatic regulation of the space that is defined between the carrier cylinder of the cutting die and the base cylinder on which the carrier sheet of the material to be die-cut slides, such as labels, so that the machine can adapt to different thicknesses, without damaging the base sheet on which they adhere.
  • the starting point is a sheet wherein a base layer of paraffined, siliconised or similar paper participates, on which an adhesive sheet per se is arranged, intended to be die-cut to obtain a plurality of adhesive labels of a smaller size.
  • the object of the device of the invention is to automate this process of regulating the positioning of the die-carrying cylinder, in order to avoid human errors and simplify this manoeuvre.
  • the invention is defined in claim 1.
  • the invention is focussed on the fact that associated to the rotation shaft of the die-carrying cylinder, and in correspondence with both ends thereof, an eccentric cam is arranged, which is linked thereto through bearings or bushings, an eccentric cam from which a lateral arm emerges which ends in a gear arc on which acts an endless screw associated to an impulse motor, with which the movement of said endless screw and consequently the angular movement of the eccentric cam, is finely controlled, which will cause,
  • the electric impulse motor can be manually controlled through a control interface, implemented in the machine itself or externally, or it can be regulated in a fully automated way through the data entered by the computer system associated with the machine.
  • the device of the invention is intended in this case to be implemented in roller-based label cutting machines, wherein a series of guide rollers (1) are used for the sheets to be die-cut, in such way that the die-cutting process takes place when said sheets are passed through a pair of rollers synchronised with each other from respective gears (2-3), establishing a base roller (4) and an upper roller (5), die-carrying, so that in this case the upper roller (5) is vertically movable on guides (6) established on the support frame (7) of the mechanism.
  • the shaft (9) of the die-carrying cylinder is offset by a small distance from the shaft (16) of the cam on which it rotates internally, so that, when the endless screw (14) is driven by means of the electric impulse motor, it causes an angular displacement of said eccentric cam (10), as shown in figure 4 , which causes a vertical displacement (D), of the shaft (9) of the die-carrying upper roller (5).
  • This device can also be used in rotary die cutting machines, when it is necessary to bring the die closer to the sheet to be cut due to its wear.
  • the mechanism can be located as mentioned in the magnetic cylinder carrying the dies (5), or in the base cylinder (4), since it is indistinct in order to carry out the intended approach, thus, in some cases it can even be incorporated into both cylinders.
  • the electric impulse motor can be manually controlled through a control interface, implemented in the machine itself and/or externally, for example through an application controlled by a mobile device, tablet or similar, and/or, be regulated in a fully automated way through the data entered by the computer system associated with the machine.

Claims (4)

  1. Vorrichtung zum Positionieren von Stanzwalzen in Rotationsschneidemaschinen, in denen die Trägerfolie der herzustellenden Etiketten durch ein Paar Rollen geführt wird, die über jeweilige Zahnräder (2-3) miteinander synchronisiert sind, wobei eine Basisrolle (4) und eine obere, die Stanze tragende Rolle (5) festgelegt sind und wobei die obere Rolle (5) auf am Tragrahmen (7) des Mechanismus angebrachten Führungen (6) vertikal verfahrbar ist, dadurch gekennzeichnet, dass mit den Enden der Achse (9) der oberen Rolle (5) über Wälzlager oder Zahnräder (11) jeweils exzentrische Nocken (10) verbunden sind, wobei von diesen exzentrischen Nocken (10) ein seitlicher Arm (12) ausgeht, der in einem Zahnradbogen (13) endet, auf den eine mit einem Impulsmotor (15) verbundene Schnecke (14) einwirkt, die mit einer internen und/oder externen Steuerschnittstelle verbunden ist, die manuell und/oder per Computer gesteuert wird.
  2. Vorrichtung zum Positionieren von Stanzwalzen in Rotationsschneidemaschinen nach dem vorhergehenden Anspruch, dadurch gekennzeichnet, dass sich der Rollenverschiebemechanismus in der Basisrolle (4) befindet.
  3. Vorrichtung zum Positionieren von Stanzwalzen in Rotationsschneidemaschinen nach dem ersten Anspruch, dadurch gekennzeichnet, dass der Verschiebemechanismus in die obere Rolle (5) und in die Basisrolle (4) eingebaut ist.
  4. Vorrichtung zum Positionieren von Stanzwalzen in Rotationsschneidemaschinen nach den vorhergehenden Ansprüchen, dadurch gekennzeichnet, dass sie die Annäherung der oberen Rolle (5) und der Basisrolle (4) ermöglicht, um den Verschleiß der Stanze auszugleichen.
