Definitions

  • the present invention refers to pallet system consisting of corrugated board layers, and a method for its execution.
  • cardboard pallets consist of a corrugated board layer or sheet whose dimensions and composition are determined as a function of the use required of the pallet, to which cross members are glued on the pallet lower side, to obtain a space between the floor surface and the cardboard layer whereupon products are laid.
  • feet are subject to strong side stresses, they may tear the paper sheet forming the cardboard layer they are glued to, and nullify the function they are provided for, i.e. to act as spacers for the insertion of the truck forks used for pallet handling and/or support of the loading plane.
  • Said depressions are obtained by punching the first paper sheet forming the cardboard and depressing the following cardboard waving or corrugation.
  • the foot is then inserted in such a depression and glued.
  • the feet are subject to strong side stresses they may come off since the foot is glued to the surface of the first paper layer of the round crown, which is no longer integral with the remaining part of the sheet, that has been punched to obtain the depression of the corrugation and form the round crown seat for the foot.
  • a further purpose of the present invention is to provide a method for manufacturing in a simple way pallets made of corrugated board layers.
  • the present invention has as its object a pallet system consisting of corrugated board layers and a method for its execution, where said pallets comprise a first cardboard layer forming the pallet loading plane and a second cardboard layer glued to said first cardboard layer and at least three spacing feet between the pallet loading plane and the floor so as to form a throughway for the insertion of lifting and handling mechanical means for said pallet, characterized in that said feet are glued to said first cardboard layer, whereas said second cardboard layer has throughholes for the insertion and fastening of the feet.
  • FIG. 1 where a perspective view of a corrugated board pallet according to the present state of art, turned upside down for convenience's sake is shown, reference number 1 indicates the pallet as a whole, number 3 a cardboard layer forming the pallet loading plane, number 2 the resting feet for the loading plane 3 on the floor.
  • FIG. 2 where a perspective view of a manufacturing system of a pallet consisting of several corrugated board layers according to the provisions of this invention, turned upside down for convenience's sake is shown, number 4 indicates the pallet as a whole, number 5 a first layer of corrugated board performing as a supporting plane for the products, number 6 a second sheet of corrugated board glued to the first cardboard layer 5.
  • Both board layers 5 and 6 are glued to each other with their relevant corrugation or waving being perpendicular to each other, in order to increase the strength of the resting plane, so that a cardboard layer hinders a possible distortion along the corrugation of the other cardboard layer.
  • Number 7 indicates the spacing feet of the resting plane 5 with respect to the floor or another underlying plane.
  • Feet 7 are tubular elements made of recycled paper inbond glued to the resting plane 5, whose diameter and thickness is suitable to bear the carrying capacity of the pallet 4.
  • Said spacing elements 7 are obtained cutting them at the required usage height from a paper tube having the required diameter and thickness.
  • the number of said spacing elements may vary depending on the pallet size and load to be carried.
  • a main factor concerning manufacture of spacers 7 is that said tubular elements work inbond and confer a higher resistance to the squashing which could be caused by the weight to be carried.
  • said second cardboard layer 6 has throughholes 8 to let them through.
  • Fig. 3 where a section of a corrugated board pallet according to the present invention is shown, number 5 indicates the first layer of corrugated board, whereas number 6 indicates the second layer of corrugated board glued to said first corrugated board layer, where the direction of the corrugation is perpendicular to each other as previously said.
  • Number 7 indicates a spacing foot inbond glued to the cardboard layer 5; number 8 indicates a throughhole on the cardboard layer 6, to let the foot 7 go through and be glued on the layer 5.
  • Said throughholes 8 have a similar and/or slightly larger diameter than the diameter of feet 7. It should be noted that the edge of hole 8, being realized by the thickness of the cardboard layer, does not allow or reduce the risk the foot to bent when subject to strong side stresses, and therefore avoids its unsticking.
  • the second cardboard layer 6 will substantially reduce to nil a possible tearing of the paper sheet forming the first cardboard layer 5, whereon the foot 7 is glued, since said paper sheet is locked by the second cardboard layer 6 glued to the first cardboard layer 5.
  • Gluing of spacing feet 7 to the cardboard layer 5 is made with hot-melt glue.
  • Cardboard pallets are generally handled by mechanical means, such as fork trucks, but in some cases they may be moved from the pallet loading station to the shipping station by conveying them on rollers, i.e. the so-called roller bands, before using mechanical means fitted with forks.
  • mechanical means such as fork trucks, but in some cases they may be moved from the pallet loading station to the shipping station by conveying them on rollers, i.e. the so-called roller bands, before using mechanical means fitted with forks.
  • roller planes usually comprise platforms fitted with balls to transfer the loads to other roller bands departing from the first one, or simply to roll the load onto the roller band.
  • the cardboard pallets are equipped with cardboard members connecting the spacing feet to each other in the sliding direction of the pallet on the roller band, as shown in the Figs. 4 and 5 and as described in the following, to avoid the risk of the feet driving into the rollers or balls with consequent distortions and/or stopping the pallet motion.
  • Fig. 4 shows a perspective view of an embodiment of a corrugated board pallet according to the object of the present invention, turned upside down for convenience's sake.
  • Number 4 indicates the pallet as described above.
  • Number 9 indicates some cardboard members whose length is equal to a dimension of the pallet 4.
  • Said members consist of two corrugated board layers glued to each other as for the resting plane of the pallet 4, not necessarily with the sense of the corrugation waves being perpendicular to each other, indicated with numbers 10 and 11, respectively.
  • the cardboard layer 10 has some throughholes 12, whose diameter is equal and/or slightly larger than the diameter of feet 7.
  • Said punched holes 12 are arranged in the same number and in line with feet 7 glued to the loading plane of the pallet 4, on the side of the pallet which slide over the roller band.
  • Members prepared as above are mounted on feet 7 of the pallet 4 by inserting the feet 7 in the throughholes 12 and gluing the feet to the cardboard layer 10 of the members 9.
  • Members 9 are glued to the feet 7 using vinyl adhesives distributed over the round section of the foot to be bonded with the member.
  • the edge of holes 12, i.e. realized by the thickness of the cardboard layer 10, will hinder or strongly reduce a possible bending of the foot, should the latter be subject to strong side stresses, so that it will not come off.
  • the second cardboard layer 10 will substantially nullify a possible tearing of the paper sheet forming the first cardboard layer 11, whereon the foot 7 is glued, since said paper sheet is locked by the second cardboard layer 10 glued to the first cardboard layer 11 forming the member 9.
  • the pallet can slide over the roller band or platform with balls without any danger for the spacing feet, since the cardboard members form a plane that can freely slide either on rollers or balls.
  • the spacers may be made in the form of a parallelepiped instead of starting from a cardboard tube, being realized through gluing and/or pressing several cardboard layers, so as to obtain a full element, which working inbond could be capable of supporting considerable weights.
