Description

    FIELD OF THE INVENTION
  • The present invention relates to the technical sector concerning production of cartons for packing applicable to tiles.
  • DESCRIPTION OF THE PRIOR ART
  • At present a firm producing and packing tiles must regularly source packing cartons and have warehouses of dimensions such as to be able to stock large quantities of cartons for packing. This complicates logistics and requires the use of warehouses of considerable dimensions.
    An apparatus for automatically cutting sheet material is given, for example, in US3844201 (A ) which concerns the production of a rigid box blank from a roll of cardboard mounted on an unwind stand. The machine disclosed in US3844201 (A ) carries out the scoring and corners cutting operations by means of successive units located along the path followed by a band of cardboard guided by tensioning and driving rollers. The units comprise scoring wheels, a press with a steel rule die and knock-out plungers.
    In particular, after unwinding, the band comes under the influence of the scoring wheels. Subsequently, the band with laterally spaced score lines passes through a press that carries a steel rule die; the steel rule die is arranged in a geometrical configuration for transversely scoring and severing the band and for longitudinally cutting the band along a line congruent with the score lines. Finally the band reaches a knocking unit where the knock-out plungers remove the corner portions from adjacent blanks; in other words the knocking unit ruptures the uncut portions in the transverse cut lines and separates the adjacent box blanks.
  • SUMMARY OF THE INVENTION
  • The aim of the present invention consists in obviating the above-cited drawbacks.
    The above aim is attained with a machine for production of a carton for packing applicable to a tile or stack of tiles, according to claim 1.
    The machine of the invention enables obtaining a carton for packing provided with a first score line and a second score line that are parallel to one another and which develop along the development direction of the carton for packing so that the following are identified: a central sector comprised between the first score line and the second score line; a first lateral sector comprised between the first score line and a first lateral end of the carton for packing; and a second lateral sector comprised between the second score line and a second lateral end of the carton for packing which is opposite the first lateral end.
    The machine of the object advantageously enables obtaining a carton for packing of various dimensions and conformation for applying to a tile or a stack of tiles.
    By way of example a first carton for packing can be realised which embraces a tile or stack of tiles at a relative first flank and part of a second flank and a third flank, the second flank and the third flank being adjacent to the first flank; to complete the packing it will be necessary to realize a second carton for packing which embraces the tile or stack of tiles at a relative second flank, opposite the first flank, and at a part of the second flank and third flank. The first carton for packing and the second carton for packing can be dimensioned such that they partially superpose on one another at the second flank and the third flank of the tile or stack of tiles. In this case, if for each of these packing cartons flaps are to be made for partially covering the upper face and the lower face of the tile or stack of tiles, it will be necessary to realize a first die-cutting in the first lateral sector and the second lateral sector at a first longitudinal portion of the cardboard band for packing, as well as a second die-cutting in the first lateral sector and the second lateral sector at a second longitudinal portion of the cardboard band for packing.
    The machine uses a reel of cardboard band for packing, which enables realising a large quantity of cartons for packing; the volume comprising the whole dimensions of the machine of the invention and the space required for stocking reels of cardboard for guaranteeing a predetermined number of cartons for packing is advantageously smaller than the volume which in the prior art is necessary for stocking the same predetermined number of cartons for packing.
    The band of cardboard for packing to be used must have a sufficient flexibility to be windable on the reel; the band of cardboard for packing is preferably provided with a first cardboard sheet, having a planar development, and a second cardboard sheet having an undulating development; the second sheet is fixed to the first sheet. With only two sheets the band of cardboard for packing exhibits the required characteristics of flexibility for being wound on a reel and has the minimum quantity of cardboard required for packing a tile or stack of tiles. The cartons for packing used in the prior art, on the other hand, also use a third sheet fixed to the second sheet, so that the second sheet, as mentioned undulating, is interposed between the first sheet and the second sheet; as a consequence, the cartons for packing of the prior art cannot be wound on a reel, as they are more rigid and heavier since they are made with a greater quantity of cardboard material.
    Overall, the unit cost of each carton for packing is reduced, for the following reasons: each single carton for packing is made with a smaller quantity of material; the cartons for packing can be realised internally of the company producing and packing the tiles, while in the prior art they are produced by third parties with prior-art machines; transport costs are also reduced, which now relate only to storing reels of bands of cardboard for packing.

    The use of the fifth conveyor and guide belt (35) and the sixth conveyor and guide belt (36), additionally to the use of the first conveyor and guide belt (31) and the second conveyor and guide belt (32), is useful for correctly guiding the cardboard band (4) for packing towards the shearing unit (18) and toward the die-cutting unit (21): in fact, the cardboard band (4) for packing in outlet from the reel (3) tends to maintain the curvature it had when wound on the reel (3) and it is therefore important to stretch it and keep it in a vertical arrangement during the pathway thereof towards the shearing unit (18) and towards the die cutting unit (21).
    The scoring means (10) are preferably arranged upstream of the shearing unit (18) with respect to the advancement direction (A).
    The scoring means (10) preferably comprise a first scoring wheel (41) and a second scoring wheel (42) for realizing the first score line (11); the first scoring wheel (41) and the second scoring wheel (42) are idle, opposite one another and act respectively on the first face (8) and the second face (9) of the cardboard band (4) for packing.
    The scoring means (10) preferably comprise also a third scoring wheel (43) and a fourth scoring wheel (44) for realising the second score line (12); the third scoring wheel (43) and the fourth scoring wheel (44) are idle, opposite and act respectively on the first face (8) and the second face (9) of the cardboard band (4) for packing.
    The first scoring wheel (41) and the third scoring wheel are interposed between the first conveyor and guide belt (31) and the fifth conveyor and guide belt (35).
    The second scoring wheel (42) and the fourth scoring wheel (44) are preferably interposed between the second conveyor and guide belt (32) and the sixth conveyor and guide belt (36).
    The above description is intended by way of non-limiting example, and any eventual constructional variants are understood to fall within the protective scope of the present technical solution, as claimed in the following.
