    DESCRIPTION
    Method for feeding laminar elements in an introducer and station device
    feeder
    OBJECT OF THE INVENTION
    The purpose of this application is to register a method for feeding laminar elements in an introducer device, a feeder station based on said process, as well as an introducer set of laminar elements, such as cardboard sheets.
    More specifically, the invention proposes the development of a method and a feeder station for the manipulation of laminar elements, preferably of cardboard, and an introducer set of laminar elements comprising an introducer device that includes the feeder station according to revindication 3, in the that turning means are arranged perpendicularly, seen in plan, with respect to an introducer device.
    BACKGROUND OF THE INVENTION
    It is known to use feeder stations (also known in the sector as "pre-feeder") that supply cardboard laminar elements to an introducer device that is arranged prior to a printing station to print at least one of the faces of the elements laminar Such feeder stations with respect to the introducer devices adopt an online configuration, that is, the feeder station and the introducer device are axially aligned with each other, in which the laminar elements move in such a way that the longitudinal element is perpendicular to the direction of advancement Although this arrangement is suitable for flexographic printing stations, it is not so much in the case of a digital printing station, in which the longitudinal axis of the laminar elements is parallel to the direction of advancement.
    When a cardboard plate leaves the corrugating machine, its most suitable face to be printed with any impression is oriented downwards. For this reason, when

    Plates are going to be printed at “top” printing stations (that is, the printing is done on the top side of the plate) have to be previously flipped.
    In the case of digital printing stations, contrary to those of flexographic printing, the cardboard plates are introduced in such a way that their longer side is parallel to the direction of advancement or introduction, this causes that in the case of laminar elements of rectangular contour with a considerable longitudinal dimension, it is complex to rotate said laminar element so that the upper face is the lower face before entering the digital graphic printing station.

    In addition, the horizontal support platform includes means of displacement on which the grouping of laminar elements (3) that comprise a plurality of transport belts (8) arranged parallel to each other, each one moving by means of pulleys, is displaced. rotating (not shown) ending in the area where the turning means are arranged.
    With regard to the aforementioned turning means they comprise a structure provided with two forks joined together as shown in Figure 4, although the number of forks could be higher, for example, four. Each fork (7) defines a housing for the arrangement of the group of laminar elements to be turned. The forks (7) are formed by a plurality of barbs (70) that pass between the free spaces existing between a plurality of conveyor belts that are part of the displacement means located in the inlet and outlet area of the turner. Said forks are linked to means of rotation (not shown) coupled to said structure, said means of rotation being associated with motor means linked to a control unit. In a preferred embodiment, the turning means comprise a central rotating shaft (20), from which the fork-shaped sections extend, which is coupled to an electric motor (not shown).
    As can be seen, the transfer device (4) comprises first transport means based on rotating rollers (11) and second transport means based on a plurality of conveyor belts (9) located parallel to each other, each linked to rotating pulleys (10), the axis of rotation of the rotating rollers (11) being perpendicular to the axis of rotation of the pulleys (10).

    Now referring to the stop means present in the transfer device (4) comprise a plate (12), which acts as a wall, which is supported on a support structure (13) axially movable on a portico structure (14 ) arranged at the top of the transfer device (4) as well as guiding means for raising and lowering the plate (12). In this embodiment, the guiding means comprise a vertical column (15) on which the plate (12) moves in a guided manner. The various movements performed by the plate (12) are managed by the control unit.
    Between the transfer device (4) and the introducer device (5) there is provided a transport structure, generally indicated by the reference (16), which allows, through displacement means, to move the grouping of laminar elements from the device transfer (4) to the introducer device (5), said transport structure (16) including a retractor stop (17) arranged in an intermediate part. Thus, as can be seen in Figures 1, 3a-3j, the reception area (2), the transfer device (4) and the transport structure (16) adopt a "L" shaped configuration.
    This retractor stop (17) is intended to distribute the laminar elements (3) individually within the introducer (5). In this way, a gradual loading is carried out in the feeding zone of the introducer device (5).
    The aforementioned displacement means may comprise a plurality of conveyor belts (18) arranged parallel to each other in a frame (19). Advantageously, in this case the conveyor belts (18) are telescopic to fit the size of the laminar body.
    Mention that if the laminar body has a width less than half of the maximum width of the introducer device (5) it is possible to work with two lines of introduction of laminar material, that is, the groups of laminar elements can be manipulated before entering the introducer device (5) so that they form two rows, as shown in Figure 3e-3j. In this case, the transport means formed by the conveyor belts (18) can operate in such a way that they are distributed in two transport groups, each transport group acting for each row.

    The operation method of the feeder station (1) for a group of laminar elements described above is detailed below.
    First, and as shown in Figure 3a, a plurality of laminar elements (3) located in a horizontal plane in a vertical grouping (A) are grouped neatly from an initial column (C) of laminar elements from , for example, of a corrugating or forming machine of the laminar elements, such that the longitudinal axis (E) of the laminar elements is located perpendicular with respect to a direction of advancement of the grouping (A), the direction of advance of the grouping perpendicular to the direction of advance (fi) of the introducer device (5).
    Next, the grouping of laminar elements (3) is turned 180 degrees with respect to an axis of rotation (not shown) that is parallel to the direction of advance of the introducing device (5), such that the upper face of each of the laminar elements is oriented downwards, as can be seen in figures 3b-3d.
    Then, as shown in Figure 3e, the grouping A of already turned laminar elements continues to move in a direction of advance perpendicular to the direction of advance of the introducer device (5) through the first means of transport to the means of transport. stop located on the transfer device. At the same time, the second group (A) enters the turner.
    Then, as shown in Figures 3f and 3g, the grouping of laminar elements moves in the same direction as the forward direction (fi) of the introducer device (5) through means of transport, the direction of feed parallel to the longitudinal axis (E) of the laminar elements (3).
    Subsequently, and as shown in Figure 3h, the grouping (A) passes through the retractor stop (17), so that the laminar elements (3) of the grouping (A) are separated and are individually arranged horizontally before to reach the loading area of the introducer device (5). In the same figure 3h it can be seen how the stop of the transfer device (4) is advanced to stop the second grouping (A) in a position that allows creating a new row of laminar elements that is parallel to the previous row.
    In Figures 3i and 3j it looks like the second grouping (A) follows the same stages as the previous grouping.
    5 Finally, in figure 3k the introducing device (5) is shown by introducing two parallel rows of laminar elements, so that two working lines are created.
    The details, shapes, dimensions and other accessory elements used in the manufacture of the feeding station of the invention may conveniently be replaced by others that do not depart from the scope defined by the claims included below.
