Definitions

  • the present invention relates to methods for printing on rigid or semi-rigid surfaces, by ink projection, by providing a positioning system of a plurality of ink projection heads to cover any desired printing width.
  • the printing roll contact technique is known, as is the non-contact technique by the projection heads, the latter being more sophisticated and of better quality for the application. inks.
  • ink projection heads are used which are of limited width, so that to cover a printing band of width greater than that of the heads, it is necessary to use multiple heads arranged so that they cover all the width of the band on which the printing is to be applied.
  • Said arrangement of several heads for composing a printing width requires in this case an exact positioning of the heads, to cover the entire width of the band to be printed, but without accumulating the ink by recovery, so that the printed surface is uniform across the width, without longitudinal stripes differentiated from the rest.
  • the invention proposes a system for positioning the printing heads, in the mentioned projection printing machines, according to a method of which satisfactorily and simply solves said positioning of the print heads.
  • the multiple heads intended to compose a print bandwidth are staggered in two transverse rows, integrating in relation to each of the heads a transverse centering mechanism and a longitudinal adjustment mechanism, in relationship with the application management of the printing that needs to be done.
  • each head is composed of a spring for thrusting the head from an edge and a usable conical screw arranged in relation to the opposite side of the head, allowing said conical screw, by its actuation, to push the head against the spring on the other side.
  • each head is composed in turn of a thrust spring which acts on the front of the head, while on the other side a usable conical screw is arranged, by which the movement of the head against the spring of the other party is possible.
  • the two movements generate a combination that makes it possible to position, in a very simple way, the different ink projection heads in each application print, to precisely adjust the necessary location of each of the heads in relation to the others. to get a totally uniform impression.
  • the distribution of the heads in the manner indicated also leads to a separation between them which makes it possible to integrate the positioning mechanisms without prejudice to the printing function that must be performed by all the heads used.
  • the system according to the invention offers certainly advantageous features, preferably for the function of adjusting the composition printing on strips via multiple ink projection heads.
  • the object of the invention is a head positioning system in projection printing machines which uses a set of heads for each ink color to cover the width of the printing tape, arranging the heads (1 ) of each printing unit into two parallel transverse lines, in a staggered distribution, as shown in FIG. figure 1 .
  • the transverse centering mechanism (1) is composed, as is illustrated on the Figures 2 and 3 a thrust spring (3) which acts on one side of the corresponding head (1), while a conical screw (4) is arranged on the other side, through which it is possible to carry out a thrust of the head (1) against the spring (3).
  • the longitudinal adjustment mechanism ( figure 4 ) is composed in turn of a spring (6) which acts in front of the corresponding head (1), while on the other side a conical screw (7) is also arranged, through which it is possible to realize in turn a thrust of the head (1) against the spring (6).
  • the operation of the heads (1) is likely to be governed by a control software, to delay or advance the start of the operation of the ink projection of each of the heads (1) when it corresponds, thus obtaining a perfect impression .
  • the heads (1) are also installed in a vertical tilt arrangement, through which they can be installed from a vertical projection position, in a horizontal projection position, to effect full-surface printing projection.
  • any part (9) of application as is illustrated on the figure 4 ; it is possible to establish the position of one any of the heads (1) in a variable inclination angle ( ⁇ ), to obtain the incidence of the projection in areas (10) over which the vertical projection can not come into proper contact, as illustrated. on the figure 5 .
