Definitions

  • the present invention relates to the technical sector concerning the realising of boxes or crates of cardboard for packaging starting from flat die-cut blanks.
  • the present invention relates to a system for storing and collecting cardboard die-cut blanks (F).
  • the cardboard die-cut blanks to be used for realising packaging boxes or crates are stored and kept in storehouses, from which they then have to be collected to be transferred to automatic packaging machines for opening them, folding them to form boxes or crates and then for packing articles therein.
  • a system used at present for storing and collecting cardboard die-cut blanks includes a storage station, wherein the die-cut blanks must be stocked and stored, and a collecting station, in which the stored die-cut blanks must be transferred then to be singly collected and transferred to the packaging machines.
  • a store is used in the storage station, comprising a fixed support plane, positioned slightly raised from the ground, on which the cardboard die-cut blanks have to be arranged and stored, one on another, to form a stack of die- cut blanks having a predetermined height.
  • This type of storehouse is known as a horizontal store, as the die-cut blanks are arranged horizontally (i.e. laid horizontally) and stacked on one another.
  • an operator has to bend to position a first group of die-cut blanks made of cardboard on the support plane, and then to position successive groups of die-cut blanks on the preceding groups up until a stack of die-cut blanks of the required height is formed.
  • the stack of die-cut blanks, thus-formed on the support plane is transferred by a transfer means to the collecting station where, time by time, a gripping means picks up the top die-cut blank of the stack of die-cut blanks and transfers it to a packaging machine.
  • a storage system of this type has various drawbacks.
  • the operator is required to make a considerable physical effort, as for each loading operation of the die-cut blanks in the storage station he must continually bend his back in order to position the first group of die-cut blanks on the support plane.
  • the support plane is not equipped, at least on one side, with guards as it must be laterally accessible to enable the operator to position at least the first group of die-cut blanks on the support plane.
  • a system for storing and collecting of this type is not efficiently adaptable to stocking of cardboard die-cut blanks obtained from a joining of two or more flat die-cut blanks glued to one another and then folded.
  • the overlapping and gluing area between two or more die-cut blanks is more raised, i.e. has a greater thickness, with respect to the other parts, which have a smaller thickness.
  • the upper part of the stack that is obtained is inclined towards the parts having less thickness. This can compromise the stability of the stack that is forming on the support plane in the storage station, but can also compromise the correct transfer thereof to the collecting station.
  • the aim of the present invention is to provide a new system for storing and collecting cardboard die-cut blanks that is able to obviate the drawbacks present in the prior art and described in the foregoing.
  • a particular aim of the present invention is to provide a new system for storing and collecting cardboard die-cut blanks that enables carrying out the loading of the die-cut blanks in an easier way for the operator, and in a condition of safety.
  • a further aim of the invention is to provide a new system for storing and collecting cardboard die-cut blanks that is flexible and efficient, independently of the shape and dimension of the cardboard die-cut blanks, and which is able to adapt, simply and immediately, to the special type of die-cut blanks, even those having a different thickness, as obtained by the coupling, gluing and folding of a plurality of die-cut blanks, and thus have different shapes and formats.
  • FIG. 1A illustrates, in a schematic plan view, the system for storing and collecting of the invention
  • FIG. 1 B and 1C illustrate the system for storing and collecting of figure 1A according to two respective schematic perspective views, taken from two different angles;
  • figure 2A is the view of figure 1 B with some parts removed better to evidence others and with the representation of an operator tasked with loading die-cut blanks;
  • figure 2B is the view of figure 1C with some parts removed better to evidence others and with the representation of an operator tasked with loading die-cut blanks;
  • FIG. 5 illustrates, in a schematic perspective view, some special components of the system of the invention.

  • the support elements (11 , 12) can be movable independently of one another enables regulation of the relative height positions according to the particular type of die-cut blanks which are to be stored. For example, in the case of die-cut blanks assembled from the coupling and gluing of various die-cut blanks, then folded with respect to one another, and which therefore have a non-uniform thickness, with the parts at the reciprocal portions that are glued having a greater thickness, the support element destined to restingly receive the thicker parts can be positioned at a lower height with respect to the rest.

  • the protective casings (17) have a height at most equal to the height of the support means (10) in the raised position (A).
