Description

"A ROLL SUPPORT ASSEMBLY"

Technical Field

The present invention relates to apparatus, methods and procedures useful in the transportation and/or storage of rolls.

Background Art

Heavy rolls, typified by coreless coils ("rolls") of sheet metal or cored paper rolls ("rolls") frequently require stabilisation during storage and/or transportation. In the case of sheet metal rolls, these are coreless, exceptionally heavy and have surfaces not to be damaged. To avoid roll to roll contact, which can be damaging, such rolls are usually individually supported away from other such rolls.

In a shipping container, owing to the great weight of such rolls, it is usual to provide rolls in alignment with the longitudinal axis of the shipping container so that the rolls can be extracted by insertion of a lifting protuberance (eg, a fork of a forklift) directly into the hollow centre of the roll. Cradling of such rolls in that condition, with or without dunnage, is used to avoid movement that is detrimental to the roll, its alignment for removal, and/or the wellbeing of the container. The present invention recognises an advantage in providing, and has as one object the provision of, a cradle support for such rolls whether, for standing storage but preferably for use in such shipping containers, which is almost exclusively (save for adhesives, eg, PVA or others) of paper or paperboard material, or at least reduces the need for less recyclable or less "green" alternatives. Such apparatus, systems and methodology has a further or alternative aim the avoidance of polystyrene usage.

As used herein "roll" in respect of the cradled or to be cradled entity can be cored or uncored ie, it can be a coil of sheet material.

As used herein the term "paper" and the term "paperboard" are to be considered interchangeable, ie, they are essentially a web or a plurality of webs (some corrugated or not) of cellulosic fibres.

As used herein the term "corrugated board" envisages paper or paperboard sheet lined laminates of fluted paper or paperboard. There can be commonality of flute run or disparate flute runs. Interposed sheet linings can be provided between such flute runs. As used herein the term "and/or" means "and" or "or", or both. As used herein the term "(s)" following a noun includes, as might be appropriate, the singular or plural forms of that noun. .

- 2 -

As used herein "flank" or "flanking" with respect to the cradle member means, if it has the preferred curved zone, on either underside of the convex curve. Likewise for any outstand or flange from the ends of the curved zone ie, the side regions underneath.

In other context, the term "flank" or "flanking" can be with respect of the relationships the cradle member has to the roll or coil to be supported ie, the outstands or flanges flank and are supported by each flanking support of the cradle member.

Figure 13 shows two such cradle assemblies mounted in a shipping container and adapted to contain a range of different size rolls,

Figure 14 shows the arrangement as in Figure 13 bearing the weight of two metal coil rolls, Figure 15 shows a dunnage assembly in accordance with the present invention bearing against one end of a roll as it would be as a dunnage unit interposed between rolls as in Figure 14, behind the furthermost roll as in Figure 14 and in front of the roll foremost roll in Figure 14,

Figure 16A shows the deployed dunnage item,

Figure 16B shows the item of Figure 16A also in perspective but from the other end when deployed, (NB normally used with hinged apex topmost), and

Figure 17 shows from below one end of a used cradle member in accordance with the present invention showing the outcome of the mutual crushing that will occur between the ribs and the cradle member to allow the settling down of a roll within an appropriate range of roll sizes as discussed with respect to Figure 8. In the preferred form of the present invention there is provided a cradling or cradle member 1 with its general shape adapted to nest with low loading (cradle to roll) a roll as shown in Figure 7. Each cradle member 1 has its curved region 2, the lower extremity of which 3 is to rest on or just above a support surface, and the outreaching flanges 4 (unitarily formed with the region 2 in preference to a fabrication process) being supported from beneath by part of an assembly 5 as described in more detail with reference to Figures 3 and 4.

The assembly 5 comprises spaced but mutually parallel profiled members 6 with a profiled edge 7 to position against the outside of the member 1. There is also an upper edge 8 which is to underlie flanges 4 to stabilise and locate the cradle member 1. The mutual spacing of the members 6 is preferably provided by a plurality of helically or other formed paper rolls 9 placed tightly through openings of each member 6 so as to provide the stability in the arrangement as shown in Figure .1.

Shown in Figure 7 is a hybrid mix of the structure as shown in Figures 1 through 4 and the alternative arrangement of Figures 5 and 6. In Figures 5 and 6 there is a fabricated adhesively attached pair of supporting sheets 10 and 11. See how in Figure 6 they are used instead of the arrangement of Figures 1, 3 and 4.

Persons skilled in the art will appreciate how, if desired, a longer roll than any of those shown in Figure 7 can be cradled between aligned pairings or groupings of the arrangements shown.

It is envisaged that the material will be a laminate of 5 times horticultural grade POWER PLY™ corrugated board. The lamination is with a suitable adhesive, (eg, PVA or other). The form of the curved cradle member is provided by placing over a jig and lower forming the roll to set the curve. The side supports 4 of a similar material can be die cut and laminated and held in place. In some preferred forms of the present invention the supports 4 can be formed integrally (and this is preferred) with the general curved region.

It is envisaged that a similar material to that of the component 1. will be used for each of the planar members 6, each will preferably be die cut to have the profiles required and the openings into which cut to length standard helically wound paperboard roll members can be inserted. Figure 8 shows how a cradle member of, say, 1255 mm diameter curve can be fitted to, say, a 662.5 mm radiused flanking member, yet with or without crushing by the coil, and thus parts of the cradle member, into the flank support, can accommodate coils of, say, from about 1255mm diameter to at least about 1655 mm diameter. By way of example, such measurements using, say, 35 mm thick cradle members linked as previously described can accommodate at least three coil sizes, the largest being preferably limited to intrude with crushing preferably no further than the top roll in the flanking member as shown in Figure 8.

A preferred range of blank components and sub-assemblies shown in Figures 13 through 17.

Figure 9 shows a preferred form of rib forming blank 10 with its three openings, each provided with some small amount of star bursting at 11.

Such a blank is of a laminate similar to that that which might be used for the cradle member 12.

The assembly can be seen from the drawings from which it can be seen that there are three blanks 10 used in each assembly of three ribs 10 in conjunction with three rolls 13. These are interference fitted but may be glued. Figωre 15 shows a dunnage item 14 of the same or different laminate. It involves a hinge strip 17 adhered to a face of each of panels 15 and 16 in such a way the edge of panel 16, when deployed, beats on a face of panel 15.

The dunnage item preferably sits against each roll as a spacer, the roll axes being parallel to the strip 17 provided hinge axes.

Figure 17 at 18 shows regions of crushed laminate arising from the mutual settling together of ribs 10 and the cradle 12 under roll weight.
