The present invention relates to the field of the transportation and storage of goods and to a transport and storage system and in particular, but not necessarily restricted thereto, a system for the transportation and storage of palletised goods.
In the field of logistics, that is the field of movement and supply of produce and materials, the transportation of intermediate and finished products is frequently assisted by the use of pallets. A pallet typically comprises a flat rectangular structure that supports goods in a stable fashion whether remaining in a transport vehicle—such as a lorry, container etc., a warehouse, storage area etc. or being lifted by a forklift, pallet truck, front loader, or other handling device. Pallets are commonly found in a wide range of industries and services, forming an essential part of many mechanical handling systems in factories, distribution warehouses and the like. Pallets are manufactured from a variety of materials, most commonly from: timber 10 per
In some areas of logistics, it has been found that the pallet has become the structural foundation of a unit load which allows handling and storage efficiencies.
For example, a unit load device (ULD) typically comprises a container used to load luggage, freight and mail on aircraft that allows a large quantity of cargo to be bundled into a single unit. Since this leads to fewer units to load, it saves ground crews time and effort and helps prevent delayed flights. Each ULD has its own packing list (or manifest) so that its contents can be checked and tracked. Further, the extensive use of 40′ and 20′ containers for transport has spurred the use of pallets because such shipping containers provide smooth and level surfaces suitable for easy pallet movement and bulk stacking of a large number of palletized loads. It is presently understood that, over half a billion pallets are made each year and about two billion pallets are in use across the United States, for example.
Typical pallet sizes are: 1200×1000 mm; 1200×800 mm; 48″×40″; being three of six ISO (International Standards Organization) sanctioned standard pallets, although there is a plethora of different sizes for specific tasks, globally. The fork tines of a fork lift or other lifting device may have limited access to a pallet, being limited to only one side, to two sides or can be provided on all four sides (1-, 2-, or 4 way entry). Pallets are reusable packaging items. Every pallet that is built could potentially be used and used again until such a time when it will need to be replaced. The lack of a single international standard for pallets causes substantial continuing expense in international trade. A single standard is difficult because of the wide variety of needs a standard pallet would have to satisfy: passing by or through doorways, placing within standard containers and unit load devices (ULDS), noting that weight, size and bulk affect the use of a standard type of load and use of a standard can reduce labour costs.
In order to maximise the storage capacity of a warehouse pallets are placed upon pallet racks, as shown in
With regard to commercial vehicles and the load capacity of such, especially of the curtain sided type, whereby access is afforded to a pallet lifter, such as a fork lift truck, from the side of the vehicle. Additionally, the goods will need to be made secure with straps, locking catches etc. It will need to be borne in mind that when a commercial vehicle goes around a corner, centrifugal forces will apply to the loads; the higher a load is situated, the greater such forces shall be.
The present invention seeks to provide a solution to the problems addressed above. The present invention seeks to provide a system that can enable goods to be securely and reliably horizontally, vertically and offset stacked, despite different sizes of base support members such as pallets, if any, whereby wasted volumes arising from the presence of irregular loads, pallets or pallets of different levels or different load ratings in storage and transport can be minimized.
Furthermore, the present invention seeks to provide a system for both pallet-borne goods and non-pallet-borne goods that protects the goods and enables stacking.
In accordance with a general aspect of the invention, there is provided a storage/transport assembly comprising first and second wall members and a cover; wherein the first and second wall members each comprise first, second and third panels, each adjacent pair of panels being hingedly arranged with respect to each other; wherein the first and second wall members are capable of being flat packed when not in use; wherein, in use, the first and second wall members provide upstanding walls about a generally rectangular cuboid storage/transport volume, the first and third panels of one wall member being arranged in facing relationship with third and first panels of the other wall member to define said storage/transport volume, the walls extending from feet operably in contact with a base support surface and rise to an uppermost lip operable to support a lower surface of said cover, at least one of the walls having at least one aperture to permit access for at least one tine of a lifting device; and, wherein the cover is operable to provide a closure extending over the storage/transport volume the walls, the cover having engagement means to locate with the uppermost lip of the walls and enable secure lateral fitment therewith and is operable to provide an upper support surface. By having a wall which can be folded in a flat fashion when not in use, the actual useful storage space of a warehouse, racking system, loading bay, lorry, train wagon or other form of ground/working area support surface can be increased. In a commercial vehicle delivery system, pallets loads can be protected and stacked; equally, non-palletised loads can be protected and stacked; whilst on a return journey a totally different type of load can be transported with the transport/storage system of the present invention being stored with a reduced space configuration, whereby to assist in a logistics business, by reducing wasted transport volume and/or wastage arising from a single-use transport/storage system.
Conveniently, the engagement means of the cover comprises one or more downwardly directed channels which limit movement of the upstanding lip surfaces of the walls upon placement of the cover on the walls. This slot-together feature has been shown to add considerable integrity to the transport/storage assembly. Additionally, the upper surface of the cover can be provided with upwardly directed features which can engage with the feet of an additional transport/storage assembly stacked thereon or allow the placement of a subsequent pallet.
The wall members of the transport/storage assembly can be fabricated from one or more types of panel including extruded polystyrene, polyurethane foam, expanded polystyrene, cardboard, laminated polyurethane foam, laminated expanded polystyrene. The laminate face can comprise, for example, one of card, plywood, polypropylene, aluminium or steel. The wall members can comprise panels and hinges, wherein the hinges enable the panels to be substantially rigid. If the wall members are formed from cardboard, then the cardboard could be folded to provide hinges integral with the cardboard structure. The cardboard employed can be selected from common grades such as single, double, triple or quadruple corrugated cardboard. Conveniently, such cardboard is treated with at least one of wax, resin, paint or other known waterproofing methods, whereby full waterproofing can be provided. Corrugated plastics panels can also be conveniently be employed.
It is recognised that, conveniently, a transport/storage assembly in accordance with the invention comprises a wall arrangement defining four panels, the dimensions of which enable the walls to be placed about or in close/abutting relationship with a pallet base or other type of product to be transported or stored or when placed upon a support surface.
The cover is conveniently manufactured from a variety of materials, such as thermo-formed plastics, moulded fibreboard, a formed plastics or moulded resin impregnated fibre or similar. An aperture or cut-out can be defined within a wall of the wall members, to enable access within the assembly. Linking members can be provided whereby to link adjacent assemblies other horizontally or vertically one with respect to the other, by means of coupling holes, straps and latches arranged along edge portions of the assemblies. Security tags can be employed to secure loads for transport and to reduce or minimise interference.
The base support surface upon which transport/storage assembly is placed can comprise one of a ground surface (generally), a floor associated with one of a support bench/storage-racking system associated a stores area, a workshop/office/storage area, a load floor of a transport vehicle and a cover of another cylindrical transport/storage assembly. By having a wall which can be folded in a flat fashion when not in use, the actual useful storage space of a warehouse, racking system, loading bay, lorry, train wagon or other form of ground/working area support surface can be increased. Conveniently, in respect of the first and/or second wall members, one of or both of respective first and third panels have radiused corners between an upstanding edge and a top edge of each said panel. This provides an advantage when positioning the components, especially when a user positions the lower edge of a second, middle panel along a ground support surface—such that there is an acute angle as between the ground surface and the inclined second panel—and pivots the wall member, such that the lower edges of the first and third wall members can be brought towards the ground support surface.
A pallet assembly in accordance with the present invention may be assembled in a rapid and expeditious manner. The two parts making up the pallet assembly may be stacked for storage in a relatively small space, conveniently being prior attached to a panel for a container, and may be associated with a container also arranged in a flat-pack style. In accordance with a still further aspect of the invention, there is provided a method of fabrication of a transport/storage assembly, the method comprising the steps of arranging the wall members in an upright position and placing the lid upon the upstanding element of the wall members.
For a better understanding of the present invention, reference will now be made, by way of example only, to the Figures as shown in the accompanying drawing sheets, wherein:—
iv-5v detail how a load can be distributed across a lid in accordance with the invention;
i, ii show a further variant detailing a form of attachment between two adjacent containers in accordance with the invention;
iii shows another form of attachment between two adjacent containers in accordance with the invention; and,
There will now be described, by way of example only, the best mode contemplated by the inventor for carrying out the present invention. In the following description, numerous specific details are set out in order to provide a complete understanding to the present invention. It will be apparent to those skilled in the art, that the present invention may be put into practice with variations of the specific.
With reference to
In the manufacture of development products, DS Smith PLC, a leading provider of corrugated packaging, supplied high performance corrugated board specifically developed for heavy-duty packaging applications. There are several standard wall board grades, thicknesses ranging from 3 mm, to 15 mm, with differentiators including the weight of the papers and the flute profiles, as well as the number of corrugations, the use of wet strength resins and wet strength adhesives to give good-excellent performance in moist or humid conditions. It is also possible to coat the board to provide further moisture protection, for example.
By the use of cardboard products, in the manufacture of containers in accordance with the invention, it will be appreciated that the product can be recycled at the end of a useful life—which will vary dependent upon specific needs/and design lifetime. Cardboard wall members can be reinforced to a degree suitable for purpose: conveniently, the cardboard wall members can be made from industry standard single, double, triple or quadruple corrugated cardboard. In view of the ability of untreated cardboard to absorb water from precipitation or from the atmosphere, the cardboard should be adequately treated, by wax, resin, paint or other known waterproofing methods. When using corrugated board formed from 440 gm−2 wet strength Kraft paper, this type of board has a weather resistance which satisfies a 2 hour water immersion test without any ply separation. In addition to a requirement for waterproofing, in order to strengthen the material, one or more of a number of options may be selected: the number of layers of sheets may be increased—e.g. for a corrugated board, the sheets as a whole, or merely just the corner sections, can be reinforced so that they have two, three of more layers; any corrugated flutes could be filled with elongate support members or strengthening members, which could be plastic rod, metal, wood or any of a number of alternative materials which can be placed within the corrugation flutes, conveniently glued or otherwise permanently attached. Distinct materials such as batons or, preferably, sheet materials can also be provided where extra strength is required. With reference to
In use, the sidewalls can be employed to surround loads in their own right or, for example, loads placed upon pallets; subsequently a cover can be placed upon the sidewalls, conveniently engaging with the upstanding edges or lips of the sidewall, to provide a secure enclosure for the load. Therefore the load is shielded from dust and other interference; the load cannot be tampered with easily and further loads can be placed upon the cover. In tests, a widely available (and therefore available at an economical cost) 15 mm board has been used for the wall members, with respect to a container suitable to surround a Euro Pallet—having dimensions of 1250 mm×1000 mm. This has been found to provide sufficient strength to support loads approaching 1000 Kg from a cover, but a safe working limit upon the covers would be 300-600 Kg. Obviously different grades of cardboard will provide different working weight limits. Using standard 15 mm thick corrugated cardboard sidewalls, for example, as a euro-pallet enclosure, it has been determined that a weight of 1000 Kg can be supported—meaning, that a working limit of 300-600 Kg can be defined, taking into account potential deterioration over time and possible incompetence of handling in use. Moreover, it has been found that standard height loads can be safely stacked up to three high, with health and safety issues necessitating a limit in view of possible overloading in use. Notwithstanding this, the skilled man will realise that a greater number of half-height transport/storage assemblies can be stacked. Compression tests have been conducted and positive results have been realised with containers made in accordance with the invention withstanding between 2800-3200 kgf (27.46-30.4 KN)—in a static load compression test. The Compression testing was conducted on a Macklow Smith compression tester with fixed platens and a load speed of 10 mm/min. The mean Peak BCT load achieved was 3035 kgf (29.76 KN). These tests were performed using devices calibrated to International Standards and the tests are based around the BS1610 standard.
iv and 5v show how the lids permit the stacking of further loads or the placement of further loads to be placed upon or act upon the lids in accordance with the system of the present invention.
Referring now to
As is known, various systems of temperature control can be implemented, with the use of foam or vacuum insulation panels (and lid), together with the use of view of coolant packages 143 such as phase-change medium (PCM) packages which are selectively cooled to provide a temperature profile for a particular class of good for a period of time—typically 24-120 hours, although such temperature profiles can only be maintained in the event that the a load volume is sealed, and in view of the apertures that are provided for the tines of a fork lift truck etc., the issue of temperature control is suitably addressed by the nature of the load carton retained within the container of the present invention.
Whilst the present invention enable greater flexibility in the positioning of loads, whether employing a pallet or not, and the stacking thereof, such stacking should only be performed subject to the ability of base-level transport/storage assemblies to take additional weight. Dependent on the height, strength and stability of the assemblies and the ability of the operator to see clearly, taller stacks may only be built following detailed consultation with the manufacturer or other competent authority. To assist in the management of closely stacked and closely coupled load enclosures or pallet enclosures, the wall members should be connectable with their associated pallets using suitable fastening means. In particular, it has been found that straps and/or panels with cooperating hook and loop fastening means provide easily applied and easily removed fastening means, although a locking bolt or similar, noting that such locking bolts, should preferably present a flush external surface finish, to enable adjacent coupling, but ideally such flush bolts can assist in the close coupling of transport/storage assemblies. The use of coloured locking straps and panels can assist in a ready indication of attachment of adjacent containers, which is not necessarily important for static storage systems, but could be quite important for maintenance of stability of loads in vehicles, ships etc. The covers can also be coupled together using similar coupling elements. In a still further modification, closing apertures and/or transparent wall sections could be defined in the walls of the container whereby access to associated documents and so-called “floating objects” and/or visibility could be provided to allow, for example, visual confirmation of contents. Conveniently, at least one of a lock, plastics security tie, crimped wire tie or similar is present whereby to provide control over access through to the inside of the container, noting that such apertures will need to be provided through two separate walls, where there is a double wall thickness.
