DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

[0021] The aforementioned figures, according to the adopted numbering, show a preferred embodiment of the invention, which comprises the parts and elements indicated and described in detail below.

[0022] A preferred embodiment of the installation for printing and die cutting for the handling of laminar bodies (P), shown schematically in FIG. 1, in general comprises a digital printing station (1) intended to print at least one face of the laminar bodies (P), being of a known type that is commercially available on the market, so it will not be described in greater detail.

[0023] In addition, the installation comprises a die-cutting station (2), also of a known type that is commercially available on the market, intended for the die-cutting of the laminar bodies (P) coming from the digital printing station, which essentially consists of a die-holding cylinder (21) facing a counter-die cylinder (20) between which the laminar body (P) travels, mounted on a base plate (22).

[0024] In FIG. 1, the arrows (f) indicate the direction of travel of the laminar bodies (P).

[0025] In addition, the installation comprises first motorised conveying means (3) to move the laminar bodies that are discharged through an opening (11) in the digital printing station (1) and second motorised conveying means (4) to move the laminar bodies (P) located before the die-cutting station (2), which will be explained in greater detail below.

[0026] The installation adopts a general L-shaped arrangement, such that the digital printing station (1) defines an axial direction of travel (f 1) of the laminar bodies (P) and the die-cutting station (2) defines an axial direction of travel (f2) of the laminar bodies

[0027] (P) that is perpendicular with respect to the axial direction of travel of the digital printing station (1), including a redirection station (5) for the laminar bodies (P) with an intake area and an output area arranged in such a way as to define a path of travel for the laminar bodies that is L-shaped seen from the plan view, which is clearly shown in FIGS. 2 and 3. In other words, an axis (EI) related to the digital printing station (1) is perpendicular to an axis (ET) associated with the die-cutting station (2) (see FIGS. 2 and 3).

[0028] Going into greater detail on the redirection station (5), it comprises a receiving area (50) for the laminar bodies (P) which has a horizontal support surface on which the laminar bodies are deposited, one on top of another to form a pile, an expulsion area (51) equipped with belts with a suction system. As shown in FIG. 1, the redirection station (5) also includes end-stop elements that are positioned in portions of the perimeter of the support surface, which in general consist of a series of platens. Therefore, the end-stop elements are fitted with a front stop platen (52) solidly fixed to the base plate that comes into contact with a side of the laminar element (P) that exits the digital printing station (1), regardless of the size of the laminar element, as well as a movable stop platen (53) that is arranged perpendicularly to the fixed front stop platen (52)

[0029] All of these elements are supported by a movable base plate (6) capable of moving in a direction perpendicular to the axial direction of travel (f1) of operation of the digital printing station (1) by means of guiding means. These guiding means on which the base plate (6) can move comprise a pair of rails (7) fixed to the surface of the floor, through which roller means (8) (shown schematically in the drawings) can slide in the direction indicated by the arrow (f3).

[0030] Now making specific reference to the first conveying means (3), they comprise a plurality of endless belts (30) arranged parallel to each other with the capacity to be extended telescopically and driven by a motor in a known manner, with one end of the endless belts (30) associated with the output area of the digital printing station (1) and the opposite end associated with the intake area of the redirection station (5). These first conveying means (3) are supported on a movable base plate (9) that, with the help of guiding means, is capable of moving in a direction perpendicular to the axial direction of travel of the laminar bodies (P) in the digital printing station (1). The movement of the movable base plate (9) is provided by the arrangement of rails (10) and roller members (90) located in the lower part of the movable base plate (9).

[0031] With respect to the second conveying means (4), they comprise a plurality of endless belts (41) arranged parallel to each other with the capacity to be extended telescopically (by conventional means), with one end of the endless belts associated with the output area of the insertion device (40) of the redirection station (5) and the opposite end associated with the die-cutting station (2) on which the laminar bodies (P) travel horizontally.

[0032] All of the movements described above carried out by the guide systems located in the installation allow the geometric centre of the stack formed by laminar bodies in the redirection station (5) to coincide with the intersection of the axes (EI) and (ET).

[0033] The details, shapes, dimensions and other accessory elements used in the manufacture of the installation of the invention may be conveniently substituted with others that do not fall outside the scope defined by the claims included below.
