Definitions

  • the present invention relates to a method and to a system for feeding blanks of packaging material to a packaging apparatus.
  • the present invention is advantageously but not exclusively applicable in the field of packaging substantially flat ceramic articles, to which the following description will make explicit reference without any consequent loss in generality. Still more specifically, the present invention is advantageously but not exclusively applicable in the packaging of one or more ceramic tiles or slabs stacked or not stacked together.
  • substantially flat articles even more specifically substantially flat ceramic articles
  • packaging machines of a known type involve the formation of the blanks that form the package from sheets of packaging material, typically cardboard, which are fed to the packaging machine, specifically to the die-cutting apparatus of said machine, to be cut, shaped and creased in order to obtain blanks suitable to be wrapped around the stack of articles.
  • sheets of packaging material typically cardboard
  • each sheet of packaging material of a known type typically cardboard
  • packaging machines have been developed with which the aforementioned blanks necessary for the packaging of substantially flat articles are produced by feeding the packaging machine, in particular the die-cutting apparatus of said machine, with packaging material wound on reels, as described, for example, in the documents BO2012A000490 or BO2013A000457 of the present Applicant.
  • Reels of packaging material are much less bulky than sheets of packaging material, allowing a reduction in storage volume for the same number of blanks produced, and are typically produced using a smaller amount of packaging material (typically cardboard) per square meter.
  • the band of packaging material (typically cardboard) must be flexible enough to be wound without being damaged and at the same time must comprise the minimum amount of cardboard necessary to safely package the substantially flat articles.
  • packaging material made in this way has a significantly lower cost per square meter than traditional three-layer sheets of packaging material.
  • the main drawbacks are related to the rate of production, which in packaging machines of this type cannot exceed ten packages per minute without the risk of compromising the quality of said package.
  • the limitations in terms of production rates are partly related to the type of packaging material; indeed, the packaging material consisting of only two layers of cardboard as described above is slightly less durable than a classic three-layer cardboard, so that if one wishes to avoid risking damaging the packaging material when it comes into contact with the sharp edges of the substantially flat articles, it is necessary to maintain limited conveying speeds.
  • the wrapping of the blanks around the stack of articles to form an actual package generally occurs by feeding a first, vertically oriented blank at a packaging station, by moving the stack of articles in a conveying direction orthogonal to the plane of the blank towards the first blank so that the stack of articles intercepting (i.e., coming into contact with) the first blank causes, with the aid of fixed intercept elements, the folding of the blank around designated score lines and the wrapping of such first blank around a first end of the stack of substantially flat articles; immediately thereafter a second, vertically oriented blank is fed at the packaging station to wrap the other end of the stack of articles by moving the stack of articles towards the further blank so that, as a result of the contact with the stack of articles and with the aid of further fixed intercept elements, the second blank is also wrapped around the stack of substantially flat articles, thereby forming the actual package.
  • packaging machines and packaging methods of the type described above require the frequent replacement of the reels of packaging material. To date, every replacement requires the intervention of an operator, with all the drawbacks associated with manual work both in terms of the time necessary for the operation, and thus of machine downtime, and costs.
  • packaging machines and packaging methods of a known type require long machine downtimes to feed the blanks to be used for the packaging of the articles.
  • the object of the present invention is to provide a feeding method and system of blanks of packaging material to a packaging apparatus which make it possible to overcome, at least in part, the limitations of the prior art.
  • a feeding method and a feeding system for feeding blanks of packaging material to a packaging apparatus are provided as set out in the following independent claims and, preferably, in any of the claims depending directly or indirectly on the independent claims.
  • reference number 1 indicates, as a whole, a packaging machine for the packaging of one or more substantially flat articles 100, stacked or not stacked together.
  • article 100 substantially designates an article 100 having a development over a plane much greater than its thickness, advantageously with a polygonal, more specifically quadrangular cross-section.
  • the present invention relates to the packaging of one or more substantially flat articles 100 stacked or not stacked together, each comprising, in particular substantially formed from, ceramic material; still more specifically, to the packaging of a polygonal, more specifically quadrangular, ceramic slab or tile. Still more advantageously but not limitatively, the present invention relates to the packaging of one or more substantially flat ceramic articles 100 that can be stacked together to form a stack of substantially flat ceramic articles 100, as illustrated in the accompanying figures which illustrate by way of example tiles with a square geometry that are packaged once stacked together.
  • the substantially flat article 100 or the stack of substantially flat articles 100 to be packaged comprises at least an upper face 2 and a lower face 3 opposite the upper face 2, at least a first flank 4a extending orthogonally between the upper face 2 and the lower face 3, a second flank 4b, parallel to and opposite the first flank 4a, a third flank 4c orthogonal to the upper and lower faces 2, 3 and to the flanks 4a, 4b, and parallel to and opposite the third flank 4d (see, for example, Figures 11 and 12 ).
  • second component does not imply the presence of a “first” component. These terms are in fact employed as labels to improve clarity and are not to be understood in a limiting manner.
  • the terms “horizontally,” “horizontal,” “vertically,” “vertical,” “externally,” “internally,” “above,” and “below” are used with reference to the packaging machine 1 which, in use, rests on a floor or ground (as illustrated, for example, in Figures 1 and 1A ) so that “above” or “below” is understood to mean, respectively, “which is above” or “which is below” another component of the packaging machine 1 when the packaging machine 1 is resting on the floor or ground as illustrated by way of example in Figures 1 and 1A , i.e. "which is further away” or “which is nearer” to the floor or ground on which the packaging machine is resting.

Still more advantageously but not limitatively, the packaging material 7 comprises (in particular, is formed by) a multilayer cardboard comprising, in turn, a first layer of cardboard, having a planar development, and a second layer of cardboard, having a corrugated development fixed to the first cardboard layer.
