Definitions

  • the present invention relates to a pallet cover for mounting on pallets, which pallet cover may protect both the load borne by the pallet and the surface of the pallet itself. Particularly, it relates to such a pallet cover, and the blank for forming the same.
  • Wooden pallets are a cheap and convenient method of handling and transporting products and materials, used widely on a daily basis. There are a number of problems with such pallets. Due to the naturally imperfect nature of the wood surface, with cracks and blemishes, dirt and microorganisms may accumulate. Clearly, if the pallet's load is a fresh product, such as a foodstuff, this accumulation of dirt is a serious problem. Some sort of barrier is needed.
  • leakage may stain the pallet, or cause it to become sticky. Again, this may be limited by the use of a cover or barrier apparatus.
  • US Patent No 6 101 955, to Salce discloses a pallet cover made of impervious materials such as metal, plastics or synthetics.
  • the pallet cover disclosed is formed into an inverted tray shape during manufacture by a moulding process.
  • the pallet cover disclosed in this patent is always in this inverted tray shape may pose difficulties in storing a plurality of such pallet covers.
  • a further problem with placing a plurality of items on a pallet is that, for the reasons mentioned above, the items are generally unstable, the higher they are stacked.
  • One approach commonly used is to use a pre-glued pallet cover, which is an inverted tray shape. This is expensive, because the trays are made beforehand, and require a large storage area.
  • the present invention and its preferred embodiments seek to overcome, or at least to mitigate, the problems of the prior art.
  • One aspect of the invention provides a method of forming a palletised load, comprising placing one or more layers of articles on a pallet, placing a cover sheet on at least one of the layers, each sheet having at least one hinged marginal flap, and stretch wrapping the layers and the sheet with a web of wrapping film, thereby folding the at least one marginal flap into a substantially perpendicular position simultaneously with the stretch wrapping.
  • the marginal flap may have rounded corners to prevent the wrapping film from being caught by the comers during the flap-folding step and thereby to facilitate the flap-folding step.
  • a second aspect of the invention provides a divider structure for placement on or in a palletised load, including a top panel and at least one marginal flap hingedly connected to the top panel.
  • the at least one marginal flap may include opposed side flaps and opposed end flaps.
  • the divider structure may be formed of paperboard or corrugated board.
  • the one marginal flap may have rounded corners so that a wrapping film is not caught on the flap corners when the palletised load is stretch wrapped by the wrapping film.
  • a third aspect of the invention provides a pallet cover comprising a cover panel hingedly connected to end panels at opposite edges of that cover panel, and hingedly connected to side flaps at each of the remaining edges of the cover panel.
  • the cover panel may correspond substantially in length and width to the pallet, such that when the pallet cover is mounted on a pallet, the end and side flaps may be folded into a position parallel and spaced from the outer faces of the pallet.
  • the cover panel may be connected to the end panels and side flaps by a series of interrupted fold lines to aid folding.
  • a fourth aspect of the invention provides a blank for the formation of a divider structure for placement on or in a palletised load, including a top panel and at least one marginal flap hingedly connected to the top panel.
  • the at least one marginal flap may include opposed side flaps and opposed end flaps.
  • the blank may be formed of paperboard or corrugated board.
  • the one marginal flap may have rounded comers so that a wrapping film is not caught on the flap corners when the palletised load is stretch wrapped by the wrapping film.
  • a fifth aspect of the invention provides a method of forming a palletised load comprising placing one or more layers of articles on a pallet, placing a cover sheet on at least one of the layers by using a robot and stretch wrapping the layers and thereby forming the palletised load.
  • Figure 1 a blank 10 for forming a pallet cover, made from paperboard or other suitable foldable sheet material, for example plastics material.
  • a blank 10 for forming a pallet cover made from paperboard or other suitable foldable sheet material, for example plastics material.
  • it is a unitary blank, although more than one blank may be used without departing from the scope of invention.
  • the blank 10 comprises a divider or cover panel 20.
  • a marginal flap hingedly connected to the cover panel 20 and, more preferably, a plurality of marginal flaps.
  • the marginal flaps are provided by end flaps 12, 14 hingedly connected at opposite ends of the cover panel 20 by the respective fold lines 22 and 24.
  • figure 1 there further comprises opposed side flaps 16, 18 hingedly connected to cover panel 20 by fold lines 26 and 28 respectively.
  • the cover panel 20 corresponds substantially in size to the pallet for which it is to be used, so that the fold lines 22, 24, 26, 28 are co-planar with and spaced from the edges of the pallet; the end panels 12 and 14, and side flaps 16 and 18 will protrude from the edges of a stack of loaded pallets.
  • apertures A1, A2, A3 and A4 are provided in cover panel 20 to aid the guiding of the blank through the production process in manufacture.
  • the fold lines 22, 24, 26 and 28 are interrupted by a series of perforations 30 along their lengths. These perforations further aid folding of the side flaps 16 and 18 and the end panels 12 and 14 into a substantially perpendicular relationship with the load panel 20 as described above.
  • Figure 2 illustrates the construction and arrangement of a cover panel 20 in a loaded pallet. It will be seen that one or more blanks 10 are placed intermediate adjacent layers of articles B in a stacked pallet P. The stack is then wrapped by application of a web of wrapping film C in the direction X. As the film is wrapped around the stack, it comes into contact with one of the marginal flaps, which causes it to fold in a downward direction Y.
  • each marginal flap 12, 14, 16, 18 is folded successively and brought progressively into a substantially parallel relationship with the outer walls of the articles B.
  • the articles continue to be stretch wrapped by the web of wrapping film to cover the sides of the pallet, and to secure the cover panel 20 in place intermediate each layer, thereby to provide a more rigid structure.
  • the marginal flaps 12, 14, 16, 18 have rounded corners to prevent wrapping film from being caught by the corners during the film wrapping process and to encourage the downward movement.
  • the film In order to control the flap folding process the film is applied at a shallow angle, for example 5 to 20 degrees and by hand or automated machinery. At a shallow angle the film will need to be placed over the marginal flaps in two or three layers.
  • An alternative or additional method of controlling the fold direction is to pre-fold the marginal flaps along fold lines 22, 24, 26, 28, either when the blank is formed or once the marginal flaps are in position in the stack.
  • one or more guides could be used in conjunction with the machinery applying the film to cause the flaps to be folded downwardly.
  • the folding of the marginal flaps in this embodiment is in a downward direction, although it is envisaged that in some embodiments it will be desirable for the base of the layer to be supported by the pallet cover.
  • the marginal flaps are folded in an upward direction.
  • the film is applied at a steeper angle, for example 25 degrees to 45 degrees and/or the flaps are pre-folded in an upward direction.
  • cover panel 10 can be used intermediate adjacent layers as a divider wall or as panel to be placed under the base or on top of the lowermost and upper layers respectively, to provide additional protection to the layers.
  • the blank can be applied below, above or intermediate the or each layer of articles by using a robot of a known type, which robot is controlled by a controller.
  • the controller also controls the stretch wrapping process and, in particular, the rate of feed of stretch film, the angle of feed and the rotational speed of the stretch film about the pallet and/or pallet speed.
  • Suitable securing means for example glue, may be applied to one or both sides of the marginal flap(s) to secure it to the article and/ or the film.
  • It is an object of the invention is to provide one or more marginal flaps which, during the process of wrapping a stack of loaded pallets, are automatically brought into a substantially perpendicular relationship with the upper surface of the article layers on which the pallet cover is mounted, such that those marginal flaps abut or are juxtaposed part of the sides of the article layer to hold the pallet cover in place on the pallet and to restrict movement of adjacent article layers.
  • hinged connection may be achieved by any of the following: a score line, a frangible line or a fold line, without departing from the scope of the invention.
