Description
i DK 166867 B1in DK 166867 B1
Den foreliggende opfindelse angår en plade med cellestruktur, hvilken plade omfatter en kerne af op til hinanden anbragte celler, som på begge sider er dækket af et dæklag eller en dækplade til 5 dannelse af en lastbærende flade eller en støtteflade.The present invention relates to a cell structure plate which comprises a core of adjacent cells which is covered on both sides by a cover layer or cover plate to form a load bearing surface or support surface.
En sådan plade kan eksempelvis bruges som lastbærende flade i en palle som beskrevet i WO-A-83/01243.Such a plate can, for example, be used as a load-bearing surface in a pallet as described in WO-A-83/01243.
Paller til opbevaring og transport af gods må opfylde en række krav. De skal være lette, billige at 10 producere, have stor styrke og stivhed mod vridning og i mange tilfælde være lette at rengøre og i øvrigt hygiejniske for at kunne anvendes, eksempelvis til transport af fødevarer.Pallets for storage and transport of goods must meet a number of requirements. They must be light, inexpensive to produce, have great strength and stiffness against twisting and in many cases be easy to clean and otherwise hygienic to use, for example for transporting food.
På denne baggrund har de fleste sædvanlige 15 paller af træ en række ulemper. Træet, som anvendes, må opfylde mange krav med hensyn til at være fri for skader, revner, råd osv., og også have en bestemt fugtighed under fremstilling og yderligere opfylde forskellige krav til styrken af sømforbindelserne og 20 lignende. Dette resulterer i, at pallerne af træ bliver relativt kompliceret og dyre.Against this background, most of the usual 15 wooden pallets have a number of drawbacks. The wood used must meet many requirements with regard to being free from damage, cracks, rot, etc., and also have a certain moisture during manufacture and further meet various requirements for the strength of the seam joints and the like. This results in the pallets of wood becoming relatively complicated and expensive.
Ved transport og håndtering af fødevarer er træpaller uhygiejniske, idet træ tiltrækker fugtighed og derved fremkalder mug. I pallens opbygning findes 25 mange kringelkroge, i hvilke smuds og bakterier kan samles. Paller af træ er også svære at gøre og holde rene, hvilket har ført til forsøg på at fremstille paller af andre lettere, stærkere og mere hygiejniske materialer.When transporting and handling food, wooden pallets are unsanitary, as wood attracts moisture and thereby induces mold. In the structure of the pallet there are 25 many hooks, in which dirt and bacteria can be collected. Wooden pallets are also difficult to clean and keep clean, which has led to attempts to manufacture pallets of other lighter, stronger and more hygienic materials.
« 30 For at eliminere ulemperne ved paller af træ er der derfor fremstillet paller af metal og forskellige plast, som har vist sig at være utilstrækkelige i styrke og anvendelighed. Der er gjort forsøg på at armere plasten på forskellig vis, eksempelvis ved hjælp 35 af glasfibre eller lignende, forstærkningsmaterialer.«30 Therefore, to eliminate the disadvantages of wooden pallets, pallets of metal and various plastics have been manufactured which have been found to be inadequate in strength and applicability. Attempts have been made to reinforce the plastic in various ways, for example by means of glass fibers or similar reinforcing materials.
DK 166867 B1 2DK 166867 B1 2
Dette medfører imidlertid ulemper, idet forstærkningsmidlet gør pallen dyrere at fremstille og yderligere forøger pallens vægt. Et andet væsentligt problem opstår som følge af krav om, at plastpaller 5 efter beskadigelse eller slid skal kunne genbruges, hvilket realiseres ved, at pallen brydes ned og omstøbes. Denne behandling vil imidlertid blive gjort vanskelig eller umulig, når pallen er af armeret plast, idet armering af glasfiber eller lignende materiale 10 bevirker et uacceptabelt slid på maskineri, som bruges til nedbrydning.However, this causes disadvantages as the reinforcing agent makes the pallet more expensive to manufacture and further increases the weight of the pallet. Another significant problem arises from the requirement that plastic pallets 5 must be recyclable after damage or wear, which is realized by breaking down and re-casting the pallet. However, this treatment will be made difficult or impossible when the pallet is of reinforced plastic, as reinforcement of fiberglass or similar material 10 causes an unacceptable wear and tear on machinery used for degradation.
Der er gjort forsøg på at fremstille paller med cellestruktur til enkelte transporter. Således er det kendt fra SE fremlæggelsesskrift 356 944 at fremstille 15 en palle af et let, billigt materiale, såsom papir, plast eller lignende, hvorved adskillige separate hylstre af nævnte materiale opstilles ved siden af hinanden for at udgøre en palle med en bikubelignende struktur. Hylstrene kan herved have cylindrisk eller 20 kantet form, og nogle hylstre er forlænget for at tjene som fødder for pallen.Attempts have been made to manufacture pallets with cell structure for individual transports. Thus, from SE Publication 356,944 it is known to produce a pallet of light, inexpensive material such as paper, plastic or the like, whereby several separate casings of said material are arranged side by side to form a pallet with a hive-like structure. The sleeves can thereby have a cylindrical or angular shape, and some sleeves are extended to serve as feet for the pallet.
Det er også foreslået, eksempelvis ifølge U.S.A. patentskrift nr. 3 587 479, 3 709 161 og 4 319 530, at fremstille paller af pap opbygget af celleformede 25 hulrum, som er fremstillet ved sammenføjning af bukkede papstrimler.It is also suggested, for example, according to U.S.A. U.S. Patent Nos. 3,587,479, 3,709,161, and 4,319,530 to produce cardboard pallets made of cell-shaped 25 cavities made by joining curved cardboard strips.
Disse paller med celleformet struktur har som allerede nævnt nærmest éngangskarakter og er først og fremmest beregnet til at lette håndteringen ved ikke at 30 skulle returneres til afsenderen, hvilket naturligvis begrænser anvendelsesområdet, og pallerne udgør i disse tilfælde en del af varernes emballage.As already mentioned, these cell-shaped pallets are almost disposable in nature and are primarily intended to facilitate handling by not having to be returned to the shipper, which of course limits the scope, and in these cases the pallets form part of the packaging of the goods.
Fra WO-A-83/01243 kendes en lastpalle, som er fremstillet af en træramme, tværgående trælister, en 35 lastflade af pap, karton, masonit eller træ og et bikubelignende materiale fremstillet af karton eller pap udstrakt i trærammen. Det bikubeagtige materiale virker DK 166867 B1 3 som et afstandsmiddel og pallen fremstilles ved sammenlimning af delene.From WO-A-83/01243 is known a pallet made of a wooden frame, transverse wooden moldings, a loading surface of cardboard, cardboard, masonite or wood and a honeycomb-like material made of cardboard or cardboard extended in the wooden frame. The honeycomb-like material acts as a spacer and the pallet is made by bonding the parts.
Fransk patent nr. 2 389 485 beskriver en plade med cellestruktur omfattende en kerne af celler belig-5 gende ind til hinanden og hermetisk lukkede. Imidlertid er cellerne adskilt fra hinanden og støtter ikke hinanden. En sådan plade har kun en fjedrende funktion og hele konstruktionen er en fjedrende og fleksibel dug, som anvendes som beskyttende emballagemateriale 10 for at beskytte skrøbeligt gods mod skader.French Patent No. 2 389 485 discloses a cell structure plate comprising a core of cells adjacent to each other and hermetically sealed. However, the cells are separate from each other and do not support each other. Such a plate has only a resilient function and the entire structure is a resilient and flexible tablecloth used as protective packaging material 10 to protect fragile goods from damage.
De beskrevne paller med celleformet struktur har, selv om de skulle fremstilles til flergangsbrug, adskillige ulemper. Strukturen med individuelle hylstre eller samlede, bukkede strimler resulterer i, at 15 materialeforbruget bliver stort, og at en palle af plast opbygget på denne måde og beregnet til at holde til flergangsbrug får en forøget vægt og derfor bliver dyr i fremstilling og brug. Anvendelsen af pap som materiale til pallen medfører på den anden side det 20 samme problem som træ, når eksempelvis det hygiejniske aspekt betragtes. De kendte paller, til hvilke pap eller papir er blevet foreslået som materiale, har på grund af deres opbygning af flere hylstre eller bukkede lag et stort antal hulrum og/eller kringelkroge, hvori 25 snavs, bakterier osv. kan samle sig.The described cellular structure pallets, although intended for multiple use, have several drawbacks. The structure of individual casings or assembled, curved strips results in a large consumption of material and a plastic pallet constructed in this way and intended to hold for multiple use is given increased weight and therefore becomes expensive in manufacture and use. The use of cardboard as a material for the pallet, on the other hand, poses the same problem as wood when, for example, the hygienic aspect is considered. The known pallets to which cardboard or paper has been proposed as material, because of their construction of multiple casings or bent layers, have a large number of cavities and / or pretzel hooks in which 25 debris, bacteria etc. can accumulate.
Den største ulempe ved de paller, som er opbygget ifølge kendt teknik af enkelte hylstre eller bukkede lag, er imidlertid, at de ikke engang med betragtelig dimensionering opnår den nødvendige styrke 30 til at modstå de belastninger, som optræder under behandlingen af pallen med eller uden last. Således vil en kraftig punktlast eller slag mod en kant eller overflade af pallen resultere i, at hylstrene eller cellerne trykkes sammen og derved giver en permanent 35 deformation, som ikke kan rettes ud, idet vægmaterialet i hylstrene og eventuelt dæklag er knækket og ikke kan gå tilbage til sin oprindelige konfiguration. Derfor er disse paller som nævnt bedst egnet til engangsbrug og DK 166867 B1 4 kan på ingen måde sammenlignes med paller af træ eller støbt, armeret plast, som skal bruges igen og igen som byttepaller på trods af den grove behandling, de ofte udsættes for.However, the main disadvantage of the pallets constructed according to the prior art of single casings or bent layers is that they do not even attain with considerable sizing the necessary strength 30 to withstand the stresses which occur during the treatment of the pallet with or without cargo. Thus, a heavy point load or impact on an edge or surface of the pallet will cause the casings or cells to compress and thereby provide a permanent deformation which cannot be straightened, the wall material of the casings and any covering layer being broken and unable to go back to its original configuration. Therefore, as mentioned above, these pallets are best suited for single use and DK 166867 B1 4 can in no way be compared to wooden or molded, reinforced plastic pallets, which must be used again and again as replacement pallets despite the rough treatment they are often subjected to.
5 Hovedformålet med den foreliggende opfindelse er på den ovennævnte baggrund at tilvejebringe en plade med cellestruktur, som eksempelvis kan bruges som lastbærende plade i en palle til flergangsbrug, hvorved de ovennævnte ulemper ved kendte paller af såvel træ, 10 'støbt plast eller med cellestruktur elimineres totalt.The main object of the present invention is to provide, in the foregoing background, a cell-structure plate which can be used, for example, as a load-bearing plate in a multi-use pallet, thereby eliminating the above-mentioned disadvantages of known pallets of wood, 10 'molded plastic or with cellular structure. in total.
Et andet formål er at tilvejebringe en sådan plade, som er specielt egnet til fremstilling af et let og relativt billigt materiale og med en udformning, som giver den stor anvendelighed ved højt satte hygiejniske 15 krav.Another object is to provide such a plate which is particularly suitable for the manufacture of a light and relatively inexpensive material and of a design which gives it great utility in high hygienic requirements.
De ovenstående og andre formål opfyldes ved en plade ifølge opfindelsen, som har de ejendommeligheder, som er angivet i de følgende krav.The foregoing and other objects are met by a plate according to the invention having the properties set forth in the following claims.
Opfindelsen vil i det følgende blive nærmere 20 beskrevet ved hjælp af et udførelseseksempel med henvisning til tegningen, på hvilken fig. 1 viser et perspektivbillede delvis i snit af en palle af plast, i hvilken palle der indgår en plade med cellestruktur ifølge opfindelsen, 25 fig. 2 et perspektivbillede af en bunddel, som er en integreret del og virker som støttefod for pallen i fig. 1, fig. 3 et perspektivbillede af en anden udformning af en støttefod for pallen i fig. 1, 30 fig. 4 et sidebillede af den lange side af pallen, fig. 5 et sidebillede af den korte side af pallen, fig. 6 en forstørret detalje af pallen angivet 35 ved en cirkel i fig. 5, og fig. 7 et perspektivbillede af pallen i fig. 1 set nedefra.The invention will now be described in more detail by way of example with reference to the drawing, in which: FIG. 1 shows a perspective view partly in section of a plastic pallet, in which a pallet with a cell structure plate according to the invention is included; FIG. 2 is a perspective view of a bottom part which is an integral part and acts as a support foot for the pallet of FIG. 1, FIG. 3 is a perspective view of another embodiment of a support foot for the pallet of FIG. 1, 30 FIG. 4 is a side view of the long side of the pallet; FIG. 5 is a side view of the short side of the pallet; FIG. 6 is an enlarged detail of the pallet indicated by a circle in FIG. 5, and FIG. 7 is a perspective view of the pallet of FIG. 1 seen from below.

Som det fremgår af fig. 1, omfatter den viste palle en lastbærende plade eller kerne 10 med cellestruktur. Cellerne har her en mangekantet facon, fortrinsvis som i den viste udførelsesform sekskantet, 5 og danner en bikubestruktur, som udstrækker sig over hele overfladen af den lastbærende flade. Ifølge opfindelsen har hver celle 12 vægge 14, som er fælles, dvs. i ét stykke med de omgivende cellers vægge 14. I modsætning til tidligere kendte paller eller 10 plader med cellestruktur er cellerne her ikke dannet af hylstre eller bukkede bånd eller strimler, men alle celler 12 er integreret til en enhedsstruktur uden nogle samlinger. Ifølge opfindelsen anvendes endvidere til den lastbærende plade et elastisk, dvs. affjedrende 15 eftergiveligt materiale, fortrinsvis plast, og den af dette materiale fremstillede cellestruktur 10 er forsynet med et dæklag 16 og 18 på både undersiden og oversiden, hvilke dæklag 16 og 18 er forbundet med cellestrukturen 10 på en sådan måde, at alle celler 20 12 hver især er hermetisk forseglet. Denne samling mellem dæklagene 16 og 18 og cellestrukturen 10 kan ske på en passende måde, eksempelvis ved hjælp af limning, svejsning eller anden sammensmeltning på en måde, som er kendt inden for plastteknikken.As shown in FIG. 1, the pallet shown comprises a load bearing plate or core 10 with cell structure. The cells here have a polygonal shape, preferably as in the illustrated embodiment hexagonal, 5 and form a honeycomb structure extending over the entire surface of the load-bearing surface. According to the invention, each cell 12 has walls 14 which are common, i.e. in one piece with the walls of the surrounding cells 14. Unlike prior art pallets or 10 sheets of cellular structure, the cells here are not formed of casings or folded ribbons or strips, but all cells 12 are integrated into a unit structure without any joints. In addition, according to the invention, an elastic, i.e. resilient 15 resilient material, preferably plastic, and the cell structure 10 made of this material is provided with a cover layer 16 and 18 on both the underside and the top side, which cover layers 16 and 18 are connected to the cell structure 10 in such a way that all cells 20 12 each is hermetically sealed. This assembly between the cover layers 16 and 18 and the cell structure 10 can be effected in a suitable manner, for example by means of bonding, welding or other fusion in a manner known in the art of plastics.
25 Idet cellestrukturen 10 på denne måde er opbygget af celler 12, som danner en enhedsstruktur uden samlinger, i hvilken hver celle 12 er lufttæt forseglet og består af et elastisk, eftergiveligt materiale, opnås en lastbærende flade med utrolig 50 styrke. Hver celle fungerer som afstivning og bærende del for hele cellestrukturen 10, idet cellerne er indbyrdes integreret, dvs. forenet til en sammenhængende helhed, og hver celle fungerer også takket være den indespærrede luftpude som støddæmper og stødopta-35 ger. Den indespærrede luftpude og cellestrukturen 10's udformning af et elastisk, eftergiveligt materiale gør også, at cellestrukturen 10 ved stød eller punktbelastninger ikke brækker, men giver fjedrende DK 166867 B1 6 efter og genindtager sin oprindelige facon, når belastningen fjernes. Den beskrevne cellestruktur 10 gør også, at den lastbærende plade har meget stor styrke mod vridkræfter og således har betydelig større vrid-5 stivhed end tidligere kendte konstruktioner.In this way, since cell structure 10 is made up of cells 12 which form a unit structure without joints in which each cell 12 is airtightly sealed and consists of a resilient, resilient material, a load-bearing surface of incredible strength is obtained. Each cell acts as a stiffener and supporting part for the entire cell structure 10, the cells being interconnected, i.e. unified into a coherent whole, and each cell also functions thanks to the trapped air cushion as shock absorber and shock absorber. The confined air cushion and the structure of the cellular structure 10 of a resilient, resilient material also causes the cellular structure 10 to not break at impact or point loads, but gives up resilient and resumes its original shape when the load is removed. The described cell structure 10 also means that the load-bearing plate has very high resistance to torsional forces and thus has considerably greater torsional stiffness than previously known structures.
Pladens øvre dæklag 16 udgør fortrinsvis, som vist i den på tegningen viste udførelsesform, pallens øvre dæk og er derved på oversiden udformet med render 20, som leder eventuel fugt og derved dannet vand til 10 drænhuller 22, som er placeret ved pallens centrum og hjørner.The upper cover layer 16 of the plate preferably, as shown in the embodiment shown in the drawing, constitutes the upper deck of the pallet and is thereby formed on the upper side with grooves 20 which direct any moisture and thereby formed water to 10 drain holes 22 which are located at the center and corners of the pallet. .
Dækket 16 er, som det fremgår af den på tegningen viste udførelsesform, eventuelt også ved de lange og korte sider forsynet med fordybninger 28 og 15 30, som også er forsynet med drænhuller 32 og 34.The tire 16, as shown in the embodiment shown in the drawing, is also optionally provided at the long and short sides with recesses 28 and 15, which are also provided with drain holes 32 and 34.
Rundt langs pallens periferi er der en kantliste 24, som er tilsluttet cellestrukturen 10 på siderne og er fastgjort til den ved hjælp af limning, svejsning eller anden samling, fortrinsvis den samme som er 20 anvendt ved fastgørelsen af dækket 16 til cellestrukturen 10. Kantlisten 24 rager et stykke op over dækket 16, eksempelvis 5 mm og danner ‘derved en ^ rundtgående kant 26. Denne kant 26 gør det muligt at stable pallerne uden risiko for, at stablen skal vælte.Around the periphery of the pallet there is an edge strip 24, which is connected to the cell structure 10 on the sides and is attached to it by means of gluing, welding or other assembly, preferably the same as used 20 for the attachment of the tire 16 to the cell structure 10. The edge strip 24 protrudes a distance above the tire 16, for example 5 mm, thereby forming a circumferential edge 26. This edge 26 makes it possible to stack the pallets without the risk of the stack tipping over.
25 Kanten 26 gør også, at gods ikke så let glider af pallen.The edge 26 also prevents goods from slipping off the pallet so easily.
På undersiden af cellestrukturen 10 er der støttefødder for pallen. Disse har form af to konsoller 36 (se også fig. 2), som har en støtteplade 38 til at 30 ligge an mod et underlag, og tre ophøjede partier 40 beregnet til at fastgøres til undersiden af cellestrukturen 10 til dennes nedre dæklag eller dæk 18. Konsollerne 36 svejses til overdelen for at danne en enhed med denne. Mellem de ophøjede dele af konsollerne 35 er der åbninger 44, se fig. 4, hvori der kan indføres løfteorganer til løft af pallen, eksempelvis ikke-viste løftegafler fra en gaffeltruck. Konsollerne 36 har også i de ophøjede partier dræningshuller 46, som er DK 166867 Bl 7 tilsluttet drasningshullerne 22 og 32 i det øvre dæk 16. Det er klart, at der er en tilsvarende dræning gennem cellestrukturen, eksempelvis via rør (ikke-vist), som går igennem denne.On the underside of the cell structure 10 there are support feet for the pallet. These are in the form of two brackets 36 (see also Fig. 2) which have a support plate 38 for abutment to a support, and three raised portions 40 intended to be attached to the underside of the cell structure 10 to its lower cover or cover 18 The brackets 36 are welded to the top to form a unit therewith. Between the raised portions of the brackets 35 are apertures 44, see FIG. 4, in which lifting means for lifting the pallet can be introduced, for example, not shown lifting forks from a forklift truck. The brackets 36 also have drain holes 46 in the raised portions 46 which are connected to the drain holes 22 and 32 in the upper deck 16. It is clear that there is a corresponding drainage through the cell structure, for example via tubes (not shown). which goes through this one.
5 Langs de korte sider af cellestrukturen 10 kan der være ekstra støtteben 48 og en støtteplade 42, som har drænhuller 50, der gennem cellestrukturen er tilsluttet hullerne 34 i dækket 16 på den ovenfor beskrevne måde. Mellem konsollerne 36 og fødderne 10 48 dannes, som det fremgår af fig. 5, åbninger 52 til indføring af løfteorganer som ovenfor beskrevet.5 Along the short sides of the cell structure 10 there may be additional support legs 48 and a support plate 42 having drain holes 50 connected through the cell structure to the holes 34 in the tire 16 in the manner described above. Between the brackets 36 and the feet 10 48 are formed, as can be seen in FIG. 5, openings 52 for inserting lifting means as described above.
Det fremgår af ovenstående beskrivelse, at der ifølge opfindelsen er tilvejebragt en bærende flade eller plade med enestående egenskaber. Pladen bliver, 15 takket være de til en enhedsstruktur 10 forenede lufttætte lukkede celler 12 af et elastisk materiale, uhørt stærk imod stød, tryk og vr idkræfter. Hver celle, som er hermetisk forseglet, fungerer som afstivning og bærende del i hele pladen eller dækket og endnu 20 vigtigere som stødoptager og støddæmper. Idet alle cellerne er afstivet af hinanden, får pladen sin store styrke mod vridkræfter samtidig med, at den indesluttede luftpude giver nødvendig affjedring til at undgå brud på materialet. Det er klart, at pladen ifølge 25 opfindelsen, selv om den er beskrevet i forbindelse med brug som en lastbærende flade i en palle,, kan bruges i mange andre forbindelser. Således kan den bruges til opbygning af ting som bakker, beholdere, skabe osv., hvor den beskrevne struktur foruden at give nødvendig 30 styrke til emnet også medfører en god isolation af dette.It will be apparent from the above description that, according to the invention, a bearing surface or plate having unique properties is provided. The plate, thanks to the airtightly sealed cells 12 of a resilient material, joined to a unit structure 10, becomes extremely strong against shock, pressure and our forces. Each hermetically sealed cell serves as a stiffener and support member throughout the plate or deck and even more importantly as shock absorber and shock absorber. As all the cells are stiffened apart, the plate gains great strength against torsional forces while providing the enclosed air cushion with the necessary suspension to avoid material breakage. It is to be understood that the plate according to the invention, although described in connection with use as a load-bearing surface in a pallet, can be used in many other compounds. Thus, it can be used for building things such as trays, containers, cabinets, etc., in which the described structure, in addition to providing the necessary strength to the workpiece, also results in good insulation thereof.
