    SHIPPING TRANSPORT UNIT
    The field of production
    The present invention relates to a transport unit comprising a plurality of sheets stacked in two or more stacks, supported by one or more load carriers (s) and enclosed by a common foil.
    Prior Art When large quantities of materials are to be transported, it is common to pack the materials on e.g. pallets to facilitate handling of the materials. The positioning on pallets makes it possible to lift and move the materials with e.g. pallet trucks or forklifts. Pallets of various sizes and typically made of wood or plastic are known and used in a wide range of business areas. The pallets are usually heavy and typically must be stored by the recipient until they can be picked up by the supplier and shipped back to the manufacturer. This results in some troublesome moving of the pallets at the receiver and also requires extra storage space for the empty pallets. In situations where materials need to be used in difficult to access locations, e.g. inside buildings or on roofs, it is essential to have as little packaging material as possible. The emptied pallets are therefore a major problem in such places.
    An attempt to solve this problem is known from DE4218354 and consists of replacing the ordinary pallets with another type of load carrier which raises the material above the ground in a similar manner to a pallet, thereby enabling handling with e.g. pallet truck or forklift. The load carriers are typically attached to the material e.g. by wrapping with foil. The load carriers are typically smaller and easier to handle than pallets. The number of load carriers required depends, of course, on the shape, size and packaging of the material to be transported. When transporting a single stack of sheets, it is customary to use two load carriers, typically designed as sheet pieces, which extend under the stack throughout its depth.
    However, when transporting multiple stacks of sheets in one unit, problems arise with the use of single load carriers in relation to pallets. Satisfactory support and stabilization of the stacks with the load carriers is difficult to achieve and there is a risk that insufficiently stabilized stacks will tip over to the user's danger.
    This is particularly problematic when the recipient of the stacks must be able to move the individual stacks independently. This is very often needed on e.g. construction sites where not all the material from one unit must be used in the same place. This requires that each individual stack can be transported and stored in a stable manner, ie without the risk that it, e.g. overturned.
    An attempt to solve one of these problems, known from W003 / 000567, consists of placing all the stacks on top of an intermediate layer and then placing the load carriers below that intermediate layer. This typically achieves good stability during transport, but in return both the load carriers and the extra intermediate layer must be disposed of after emptying. These together make up pretty much as much extra material as a regular pallet. Furthermore, it is very difficult or impossible to lift and transport only one of the stacks separately from the others, as mentioned above very often. It is simply not possible to get a pallet truck or forklift truck in between the large plate and one of the stacks, the stacks being directly on top of the plate.
    Another attempt to solve the problems is known from EP0946394 and consists of using three load carriers for two stacks of sheets. One load carrier is placed below the dividing line between the two stacks and parallel to it, while the 3 3DK 2006 00223 U4 the other two are located further below each stack and parallel to the middle one. The stacks and carriers are wrapped with a common foil. However, this solution is very sensitive to the displacement of the middle load carrier. Such a shift can make the stacks unstable and cause them to overturn. These units thus place great demands on the precision in the production of the unit, which makes it difficult and expensive. When separating and moving the two stacks separately, additional problems arise, with only the extremely placed load carrier accompanying the single stack after the separation. The stack is not stable with only this extremely placed load carrier, and overturns as soon as it is lowered. This is of course both dangerous and very impractical. It is possible to manually support the individual stack after separation and relocation, but this requires the existence of suitable load carriers and this takes time.
    As can be seen, none of the known methods solves the problems of handling and moving materials in a safe and efficient manner.
    The receivers of materials on pallets or load carriers are typically e.g. large warehouses or construction sites. Both places are workplaces where work must be done at a high pace and where there are already significant risks associated with operating machines and handling materials. Thus, it is required that the handling of materials takes place as efficiently and risk-free as possible. Of course, cumbersome procedures increase the consumption of time and thus cost the work. Unsafe handling and relocation of materials add another security risk to the already dangerous workplaces.
    Thus, as can be seen from the above, there is a need to provide a new way of transporting materials which solves the above problems.
    There is also a need to provide a transport unit that leaves as little packaging as possible with the recipient, but which is stable and simple and safe to use.
    There is also a need to provide a transport unit which makes it easy and safe to handle and move a single stack from a multi-stack unit.
    Furthermore, there is a need to provide a unit for transport which is simple and fast to produce.
    Summary of the production
    The object of the present invention is thus to provide a transport unit which meets these needs and effectively solves the above problems.
    The production is new and peculiar in that each of two or more stacks is separately supported by one or more load carrier (s) and in that the foil is a tubular stretch film having radially elastic properties and axial elastic or inelastic properties arranged horizontally about one another. the stacks and said one or more load carriers (s) to hold them together and ensure the stability of the transport unit during handling and transport.
    Separately supported, in this context, it should be construed as meaning that each load carrier is placed under one stack alone and thus does not come in contact with any spaces between the stacks.
    Placing the tubular stretch film horizontally about the stacks and said one or more load carrier (s) significantly increases the stability of the transport unit, thereby minimizing the required number of load carriers. In addition, the stacks and load carriers are held together by the pressure created by the stretch film. This pressure increases friction between the stacks as well as between the stacks and the load carriers. This effectively prevents displacements of the stacks relative to each other and of the load carriers relative to the stacks. This means that fewer load carriers can be used as the stacks due to friction hold each other in place. Thus, both increased stability and the possibility of using fewer load carriers are achieved without the need for further stabilization of the transport unit. Horizontally, in this context, should be perceived as substantially parallel to the upper and / or lower faces of the stacks.
    Preferably, the tubular stretch film of polyethylene, especially the type of low density polyethylene, is of a radial and axial direction. In this context, the axial direction should be construed as the direction parallel to a central axis extending through the cavity of the tubular stretch film and out through both ends. The radial direction should be perceived as the direction perpendicular to this center axis.
    Advantageously, the tubular stretch film has a thickness of approx. 30-200 pm, more advantageously approx. 50-150 pm and most advantageously approx. 80-130 pm.
    Advantageously, the tubular stretch film can be stretched approx. 5-100% in the radial direction, more advantageously approx. 10-70%, most advantageously 15-50%.
    These properties of the tubular stretch film allow one to select a stretch film with a smaller circumference than the circumference of the stacks and associated load carrier (s). The stretch film is expanded radially so that the stacks with load carrier (s) can be inserted horizontally into the expanded stretch film, after which the stretch film will sit tightly around the stacks and load carrier (s) in the finished transport unit.
    Preferably, the sheets may be made of a material suitable for insulation such as e.g. glass wool or stone wool. These materials are particularly suitable for incorporation into transport units according to the present invention, with the friction between bonded insulating sheets being extremely high. This friction contributes to the stability of the transport unit.
    The plates may also be made of other materials suitable for packing in a conveyor unit of the present type, e.g. wood, plastic, fiber or rubber. These materials are all suitable for transport in stacks using the present invention.
    6 DK 2006 00223 U4
    Preferably, said one or more load carrier (s) may be made of the same material as the plates. This is advantageous because the load carriers can be used in the same process as the plates are used. In this way, the load carriers are no longer considered packaging material and should therefore not be disposed of in the usual sense. Thus, the amount of waste which is a nuisance and inconvenience to the recipient of the plates is minimized.
    Said one or more load carrier (s) may further be made of any solid material suitable for support and support, e.g. wood, metal, fiber, electricity. like. In this context, solid material means that the material does not give up significantly when it is loaded with a weight. The important thing is that the load carriers are not compressed under the stacks and therefore the choice of material for the carriers should be adjusted to the weight of the stacks.
    Said one or more load carrier (s) may be in the form of blocks, cubes, cylinders or other geometric shapes.
    Preferably, the plates have width, depth and height, and said one or more load carriers (s) have a width substantially equal to a fraction of the width of the plates, a depth substantially corresponding to a fraction of the depth of the plates, and a height which essentially corresponds to a fraction of the height of the plates. This is advantageous because the load carriers can thus easily be handled in the same workflows used to handle the plates.
    Preferably, each stack may have a vertical plane of gravity and each load carrier may be substantially aligned with a vertical vertical plane of gravity. Such placement of a load carrier relative to a stack can make handling and moving of a separate stack simple and safe, since the stack can rest on the load carrier without the risk of tipping over.
    In this context, a vertical vertical plane of gravity must be understood as the vertical plane passing through the center of gravity of the stack, which is perpendicular to the ends of the stack, as well as upper and lower surfaces and parallel to the sides of the stack.
    Preferably, a predetermined distance between several load carriers may be 500 mm or more. Such a distance ensures that the lifting arms from e.g. a forklift or a general-size pallet truck can enter between the load carriers and thereby be able to lift the transport unit. For adaptations to other lifting methods or purposes, the load carriers may be placed at any other advantageous distance, which at the same time ensures the stability of the supported stacks and the transport unit as a whole.
    Preferably, the number of load carriers in a given transport unit may be equal to or greater than the number of stacks in the given transport unit. Keeping the number of load carriers low ensures that the amount of packaging material is kept low even at multiple stacking units. Thus, a transport unit with few load carriers, in the case where the carriers are of a different material than the plates, is all equally advantageous compared to one with many carriers, the former leaving at least packaging material in the form of carriers.
    Brief description of the drawings
    The invention is explained in detail below with reference to particular preferred embodiments and the drawings, wherein
    FIG. 1 is a front view of a transport unit with two stacks and two load carriers; and
    FIG. 2 is a bottom view of a transport unit with two stacks and four load carriers.
    Both figures are schematic, of course not to the extent, and show only parts that are necessary to clarify the production, while the other parts are omitted or merely indicated. The same reference numbers are used in both figures for identical or similar details.
    Detailed Description of the Invention In FIG. 1 is a perspective view of a transport unit 1 according to the invention comprising plates 2, two stacks 3, load carriers 4 and stretch film 5 placed horizontally about the stacks and load carriers.
    The plates 2, which may be included in the transport unit 1 according to the manufacture, may be, for example, of wood, plastic, metal, glass, stone, fiber, rubber, or a combination thereof. Preferably, the sheets 2 according to the manufacture may be made of a material suitable for insulation such as glass wool or rock wool.
    Although the transport unit 1 of FIG. 1 is shown with two stacks 3 of plates 2, it is within the scope to use a different number of stacks 3, for example three, four or more.
    Likewise, the production does not limit itself to the use of two load carriers 4, but also includes the use of three, four or more load carriers 4. Preferably, the number of load carriers 4 may be equal to or greater than the number of stacks 3. A relatively low number of load carriers 4 in relation to the number of stacks 3, everything else provides an easier working process in the production of the transport units and at the same time results in less packaging material in the form of carriers 4.
    Said one or more load carrier (s) 4 according to the invention may be of a solid material suitable for support and support, for example wood, metal, fiber, electricity. like. Preferably, said one or more load carrier (s) 4 may be of the same material as the plates 2 of the transport unit 1. This is advantageous, since the user of the plates 2 will thus typically be able to use said one or more load carrier (s) 4 in the same working process and thereby avoid having to dispose of them otherwise. This is particularly advantageous in places where transporting material to and from the site is cumbersome or associated with high costs, e.g. on roofs or inside buildings.
    The stretch film 5 is shown in FIG. 1 is positioned horizontally about the stacks 3 and the load carriers 4, and according to the production can be of polyethylene, in particular the low density polyethylene type, having a radial and an axial direction and with elastic properties in the radial direction and inelastic properties in the axial direction.
    In a preferred embodiment, the stretch film 5 has a thickness of approx. 80-130 μπι, but it is within the scope of the present invention to use stretch film 5 of different thicknesses, e.g. 30-200 μιτι or approx. 50-150 pm. In one embodiment of the production, the stretch film 5 can be stretched approx. 15-50% in the radial direction, but it is within the scope of using stretch film 5 with other radial elastic properties, e.g. a possible radial stretch of approx. 5-100% or approx. 10-70%.
    Although the preferred embodiments of the present invention utilize a stretch film 5 which is substantially inelastic in the axial direction, it is conceivable that a stretch film 5 having certain elastic properties in the axial direction will be advantageous in other embodiments.
    The manufacture of the transport unit 1 is typically carried out by first stacking the plates 2 into two or more stacks 3. Then one or more load carriers <e) 4 are typically placed on top of the stacks 3. Subsequently, the stacks 3 are transported with said one or more load carriers (e} 4 , typically by means of a conveyor belt, to a unit which holds a radially expanded tubular stretch film 5. The stretch film 5 is typically open at one end but may be open at both ends The stacks 3 with load carrier (s) 4 move in in the tubular stretch film 5, which is thereby released from the unit which previously held it, thereby being placed tightly around the stacks 3 and said one or more load carriers (e) 4. The stretch film 5 extends strongly upon the release from the unit which held it radially, thereby exerting a force on the stacks 3 and the load carrier / ne 4. This force holds the stacks 3 and the load carrier / ne 4 together and increases the friction between them. s 5 axial inelastic properties that the stacks 3 are held tightly together and the friction between the stacks 3 makes the transport unit 1 stable. Finally, the tubular stretch film 5 is closed, typically by welding, the transport unit 1 is turned downwards with the load carriers 4 and is then ready for pick-up or removal.
    Surprisingly, it has been found that a transport unit 1 with two stacks 3 of plates 2 can be stably supported by just one load carrier 4 located under each stack 3, without the need for a stabilizing connection between the two stacks 3, e.g. in the form of a continuous plate, a common load carrier under the space between the stacks or the like. This has until now been an inconceivable solution, as the commonly used distance between the load carriers 4 of at least 500 mm combined with the width of the plates 2 would cause the stacks 3 to fall towards the middle and the unit thereby unstable. Only by using a transport unit 1 according to the present invention has it been possible to achieve the above stabilization, i.a. by virtue of the unforeseen and surprisingly stabilizing effect of the tubular stretch film 5, FIG. 2 is a bottom view of a transport unit 1 according to the invention comprising plates 2, two stacks 3, four load carriers 4 and a stretch film 5.
    The load carriers 4 are shown in FIG. 2 shown as being rectangular from the bottom, but according to the embodiment, the load carriers 4 may be formed as blocks, cubes, cylinders or other geometric shapes. Preferably, the load carriers 4 may have a width, depth and height substantially corresponding to fractions of the spatial dimensions of the plates 2. This usually means that a given total number of load carriers 4 together has the same outside dimensions as one or more plate (s) 2. For example, one can have four load carriers 4 under two stacks 3 of plates 2, each load carrier 4 being 11 DK 2006 00223 U4 approx. H of the size of a plate 2. Thus, the four load carriers 4 can collectively fill the same space as a whole plate 2, and thus more easily form part of the handling of the user in question.
    Load carriers 4 having a width, depth and height which correspond substantially to fractions of the spatial dimensions of the plates 2 are particularly advantageous if the load carriers 4 are simultaneously of the same material as the plates 2. In this case, the load carriers 4 can typically be included directly in the given work process.
    The load carriers 4 are shown in FIG. 2 shown as being spaced apart. The distance between the load carriers 4 is defined as the length of the gap between the load carriers 4 measured along the edge of the lower plate (s) 2. This is the relevant distance, as it is here, e.g. the lifting arms of a pallet truck or a forklift truck can enter under the transport unit 1. By various means of moving and lifting the transport unit 1, the distance between the load carriers 4 can be more or less significant. Preferably, the load carriers 4 may have a predetermined spacing of 500 mm or more. 500 mm is the usual minimum width of the lifting arms of a pallet truck or a forklift truck, and is thus a particularly advantageous distance between the load carriers 4 if the transport unit 1 is to be handled with a pallet truck or a forklift truck.
    Furthermore, it is clearly seen in the FIG. 2 shows that the transport unit 1 can be advantageously handled with a pallet truck or a forklift from all sides, the four load carriers 4 all being spaced apart. This further provides the advantage that if the tubular stretch film 5 is cut through at the gap between the two stacks 3, the two stacks 3 can be transported separately and used in different locations.
    Preferably, the load carriers 4 may be positioned substantially in vertical with at least one stack 3 vertical plane of gravity. Such a placement increases the stability of the individual stack 3, and thus makes this stack 3 stable even after an event. separation from the transport unit 1. Thus, it becomes possible to move around with individual stacks 3 from a transport unit 1 without risking that the stacks 3 overturn to the detriment and danger of the surrounding.
