Description

"LASTEPALL" "LOAD PALLET"

Foreliggende oppfinnelse går ut på en lastepall av den art som anvendes ved transport av omfangsrike gjenstander for å be-skytte disse og for å muliggjøre håndtering med f. eks. gaffel-trucker eller liknende. De hittil anvendte paller av denne art er innen Europa standardisert til et begrep som kalles Eiropapal-len. ( I Sverige forekommer også betegnelsen SJ-pallen). Disse paller er gedigent utført av tre, og ønskes som regel i retur av avsenderen. Pallene er forholdsvis kostbare og tunge og er der- The present invention is based on a loading pallet of the kind that is used when transporting bulky objects to protect them and to enable handling with e.g. forklifts or similar. The pallets of this type used up until now have been standardized within Europe to a term called the Eiropapal. (In Sweden, the designation SJ-pallen also occurs). These pallets are solidly made of wood, and are usually wanted in return by the sender. The pallets are relatively expensive and heavy and are there-

for brysomme å håndtere. Pallene er forholdsvis kostbare "flisete" og tunge og er derfor brysomme å håndtere. En betydelig ulempe med disse paller er dessuten at de ved skader knapt kan repareres og at påny-anvendelse av virket krever fjerning av spikerne, hvilket er kostbart. "Avfallsmengden" fra disse paller er betydelig . too troublesome to handle. The pallets are relatively expensive, "chippy" and heavy and are therefore troublesome to handle. A significant disadvantage of these pallets is also that they can hardly be repaired if damaged and that reuse of the wood requires the removal of the nails, which is expensive. The "amount of waste" from these pallets is significant.

Disse ulemper gjør at lastepallene bidrar vesentlig til de høye transportutgifter. Den største andelen ligger herunder i den manuelle håndtering ved alle flytninger av paller uten gods. These disadvantages mean that the pallets contribute significantly to the high transport costs. The largest proportion lies below in the manual handling of all movements of pallets without goods.

Foreliggende oppfinnelse går ut på en lastepall, somThe present invention is based on a pallet, which

er utført av sponskivemateriale, lim og papphylser, som ikke er beheftet med ovennevnte ulemper. Den er også lettere og billigere enn tidligere konstruksjoner. En annen fordel med lastepallen ifølge oppfinnelsen er at den ikke inneholder spiker eller liknende. Den kan derfor med fordel utføres som en engangsemballasje, som kan samles sammen og sendes tilbake direkte til fabrikanten for-nedmaling og for fremstilling av nye sponplater eller liknende. Lastepallen ifølge oppfinnelsen, i første rekke engangspallen, krever en annen rutine ved transportoperasjonene enn den som tidligere ble anvendt. Engangspallene oppsamles og sendes tilbake til leverandøren av sponplater i transporter med passende mellom-rom . is made of sponge disc material, glue and cardboard sleeves, which are not affected by the above-mentioned disadvantages. It is also lighter and cheaper than previous designs. Another advantage of the loading pallet according to the invention is that it does not contain nails or the like. It can therefore advantageously be carried out as a disposable packaging, which can be collected together and sent back directly to the manufacturer for painting down and for the production of new chipboards or the like. The loading pallet according to the invention, primarily the disposable pallet, requires a different routine for the transport operations than that previously used. The disposable pallets are collected and sent back to the chipboard supplier in transports with suitable spaces in between.

Tilbakeføringen av materialet for fremstilling av nye sponplater innebærer en nasjonaløkonomisk fordel, og minsker den totale avfallsmengde. The return of the material for the production of new chipboard involves a national economic advantage, and reduces the total amount of waste.

Slike "gjenvinnbare" lastepaller er i og for seg tidligere kjent.blant annet fra svensk utlegningsskrift nr. 356 945, men de har hatt andre ulemper, vanligvis bestående i sviktende styrke, hvilket har begrenset deres anvendelse betydelig. Such "recyclable" loading pallets are in and of themselves previously known, among other things from Swedish specification no. 356 945, but they have had other disadvantages, usually consisting of failing strength, which has significantly limited their use.

Variasjonsrikdommen av denne kjente teknikk viser med all ønskelig tydelighet vanskelighetene med å få frem en engangs-lastepall av foreliggende art. Kravene til en slik pall kan sam-menfattes slik: 1) Den skal være så billig i fremstilling at den virkelig kan anvendes som engangspall. The wealth of variation of this known technique shows with all desirable clarity the difficulties in producing a disposable pallet of the present kind. The requirements for such a pallet can be summarized as follows: 1) It must be so cheap to manufacture that it can really be used as a disposable pallet.

2) Den skal lett og økonomisk kunne lages til avfall,2) It must be easy and economical to make it into waste,

det vil si helst kunne males direkte til ny fibermasse på en lønnsom måte 3) Den skal være sterk nok til å erstatte tidligere anvendte standardpaller. that is to say, ideally it can be ground directly into new fiber pulp in a profitable way 3) It must be strong enough to replace previously used standard pallets.

En kjent pall (ifølge det amerikanske patentskriftA known pallet (according to the US patent document

nr. 2.444.184) turde være den som hittil er kommet nærmest til oppfyllelse av disse ønskemål. Den oppfyller vilkårene 1) og 2), men har ikke vist seg tilstrekkelig sterk hvis man ikke anvender materiale av forholdsvis kostbar kvalitet, da vilkår 1) ikke lenger oppfylles. No. 2,444,184) would be the one that has so far come closest to fulfilling these wishes. It fulfills conditions 1) and 2), but has not proven to be sufficiently strong if material of relatively expensive quality is not used, as condition 1) is no longer fulfilled.

Den amerikanske pall er imidlertid bestemt som en engangspall og den er forsynt med fiberplate og sylindriske klosser av limt papir eller liknende. The American pallet, however, is intended as a disposable pallet and it is provided with fiberboard and cylindrical blocks of glued paper or similar.

Søkeren i foreliggende sak har utført prøver med paller av denne art med påklistrete klosser og disse prøver har vist at med tilstrebet billig materiale er tilstrekkelig styrke ikke oppnådd ifølge den amerikanske konstruksjon. Limet mellom klosser og plate blir nemlig sterkere enn fiberplatene og pallhylsene i seg selv, hvilket gjør at hylsene brekkes løs forholdsvis lett ved at ytterskiktene løsner. The applicant in the present case has carried out tests with pallets of this type with glued-on bricks and these tests have shown that with the cheap material used, sufficient strength has not been achieved according to the American construction. The glue between blocks and board becomes stronger than the fiber boards and pallet sleeves themselves, which means that the sleeves break loose relatively easily as the outer layers loosen.

Den utprøvete pall med på overflaten pålimte klosser ifølge det amerikanske patent viste seg således ikke å ha tilstrekkelig styrke til å kunne konkurere med de foreliggende tré-paller. The tested pallet with blocks glued to the surface according to the American patent thus proved not to have sufficient strength to be able to compete with the available wooden pallets.

Gjenstanden for oppfinnelsen har derimot uttak i dekket for klossene. Slike uttak er i og for seg kjent i form av spor ifølge amerikansk patentskrift nr. 2.836.384, men de kjente spor er meget grunne. Det har vist seg at en økt dybde øker styrken netopp over den grense som' markerer minimumskravet til en lastepall. På dette område innebærer selv en moderat vinning med hen-blikk på styrken, et betydelig fremskritt. The object of the invention, on the other hand, has an outlet in the tire for the cleats. Such outlets are in and of themselves known in the form of grooves according to US Patent No. 2,836,384, but the known grooves are very shallow. It has been shown that an increased depth increases the strength just above the limit which marks the minimum requirement for a pallet. In this area, even a moderate gain in terms of strength means significant progress.

Nylig utførte prøver viser at denne økning av limfugens overflate virkelig spiller'en avgjørende rolle.for pallens styrke, fremfor alt hvis uttagningens dybde overstiger halve .sponplatens tykkelse. Recently carried out tests show that this increase in the surface of the glue joint really plays a decisive role for the strength of the pallet, above all if the depth of the recess exceeds half the thickness of the chipboard.

Tre utførelsesformer for oppfinnelsen skal beskrives nærmere i det følgende under henvisning til vedlagte tegninger, hvor fig. 1 viser én lastepall ifølge oppfinnelsen sett ovenfra. Three embodiments of the invention shall be described in more detail below with reference to the attached drawings, where fig. 1 shows one loading pallet according to the invention seen from above.

Fig. 2 viser et snitt gjennom anordningen ifølge fig. 1, etter linjen II-II. Fig. 3 viser en modifisert utførelsesform, spesielt bestemt for lettere gods, sett ovenfra. Fig. 4 viser samme pall i snitt IV-IV på fig. 3. Fig. 5-7 viser snitt gjennom forskjellige befestigelser av klosser til lastepallens dekk. Fig. 2 shows a section through the device according to fig. 1, after the line II-II. Fig. 3 shows a modified embodiment, especially intended for lighter goods, seen from above. Fig. 4 shows the same pallet in section IV-IV in fig. 3. Fig. 5-7 shows sections through different fastenings of blocks to the deck of the pallet.

Den på fig. 1 viste utførelsesform består av en sponplate 1, hensiktsmessig ca. 1 centimeter tykk og fortrinnsvis i forbindelse med standardiserte mål, det vil si ca. 120x80 centimeter. I denne sponplaten er symmetrisk opptatt tre rekker med tre sirkulære spor i hver, det vil si 9 hull, hensiktsmessig med en ytre diameter på omkring 12 centimeter og en indre med 10 centimeter. I disse hull.er innpresset og fastlimt sylindriske papphylser 2, hensiktsmessig med omkring 1 centimeters veggtykkelse. Det har vist seg økonomisk herunder å utnytte slike papphylser, som forekommer i stort antall som oppviklingsakser til omkring 12 centimeters høyde. Disse innsettes i sporene i platen, hvilket The one in fig. The embodiment shown in 1 consists of a chipboard 1, suitably approx. 1 centimeter thick and preferably in connection with standardized measures, i.e. approx. 120x80 centimeters. In this chipboard, three rows with three circular grooves in each are symmetrically occupied, that is, 9 holes, suitably with an outer diameter of around 12 centimeters and an inner diameter of 10 centimeters. Cylindrical cardboard sleeves 2, suitably with a wall thickness of around 1 centimeter, are pressed into these holes and glued. It has proved economical to utilize such cardboard sleeves, which occur in large numbers as winding shafts up to a height of around 12 centimeters. These are inserted into the grooves in the plate, which

har vist seg også å øké platens styrke betydelig sammenliknet med hvis hylsene 2 limes direkte på den undre overflaten. Befestigelsen av hylsene blir også betydelig stødigere på denne has also been shown to increase the plate's strength significantly compared to if the sleeves 2 are glued directly to the lower surface. The attachment of the sleeves is also significantly more stable on this one

. måten.. the way.

Som allerede nevnt har det vist seg hensiktsmessigAs already mentioned, it has proven to be appropriate

å anvende en sponplate med omkring 1 centimeters tykkelse av en kvalitet, som i handelen betegnes kvalitet 2. Platens motstands-evne mot væte og dens styrke økes hvis den overtrekkes med et lag av f. eks. plastlakk eller liknende. En pall med de ovenfor to use a chipboard with a thickness of about 1 centimeter of a quality, which in the trade is called quality 2. The board's resistance to moisture and its strength is increased if it is coated with a layer of e.g. plastic varnish or similar. A pallet with the above

som eksempel angitte mål og dimensjoner får en vekt på omkring 8 kg, hvilket under håndteringen bør sammenliknes med den tradisjonelle Europapall, som veier omkring 25 kg. For tungt gods oppviser den tradisjonelle trepallen høyere styrkesifre, men den er i de fleste forekommende tilfeller oversterk, hvilket gjør at platen ifølge oppfinnelsen med fordel kan anvendes ved de fleste transporter av f. eks. kjøleskap, elektriske komfyrer og annet stykkgods. Pallen ifølge fig. 3 og 4 egner seg i første rekke for transport av bun-tete wellpappkartonger, hvor lastevekten på en pall sjelden overstiger 400 kg. as an example, given measurements and dimensions result in a weight of around 8 kg, which during handling should be compared with the traditional European pallet, which weighs around 25 kg. For heavy goods, the traditional wooden pallet shows higher strength figures, but it is in most cases too strong, which means that the plate according to the invention can be used with advantage in most transports of e.g. refrigerators, electric cookers and other general goods. The pallet according to fig. 3 and 4 are primarily suitable for transporting bundled corrugated cardboard boxes, where the load weight on a pallet rarely exceeds 400 kg.

Fig. 1 og 2 viser en utførelsesform hvor tre strimlerFig. 1 and 2 show an embodiment where three strips

av sponplaten er anvendt til å forsterke pallens underside.of the chipboard is used to reinforce the underside of the pallet.

Ved det viste utførelseseksempel har disse strimler 3 en breddeIn the embodiment shown, these strips 3 have a width

på omkring 12 centimeter, og er forsynt med ringformete spor for papphylsenes frie ender. De limes fast på samme måte som ved den øvre sponplaten 1 og er utført av samme materiale som denne. of around 12 centimetres, and is provided with ring-shaped grooves for the free ends of the cardboard sleeves. They are glued in place in the same way as for the upper chipboard 1 and are made of the same material as this.

En på denne måte forsterket lastepall ifølge oppfinnelsen får en vekt på omkring 15 kg,men dens styrke under forekommende påkjen-ninger ligger meget nær den tradisjonelle trepallens. I motsetning til denne kan lastepallen ifølge oppfinnelsen skades betydelig uten å gi årsak til utstikkende splinter med spiker, som i mange tilfeller er en direkte fare for den som behandler pallene. Ut fra et arbeidsbeskyttelsessynspunkt er derfor pallen ifølge oppfinnelsen betydelig overlegen. A pallet reinforced in this way according to the invention has a weight of around 15 kg, but its strength under occurring stresses is very close to that of a traditional wooden pallet. In contrast to this, the loading pallet according to the invention can be significantly damaged without causing protruding splinters with nails, which in many cases are a direct danger to the person handling the pallets. From a work protection point of view, the pallet according to the invention is therefore significantly superior.

Fig. 5 viser et snitt gjennom befestigelsen av en kloss mot dekket ifølge f. eks. det amerikanske patentskrift nr. 2.444.184. Klossens middeldiameter betegnes med D og materialtyk-kelsen av såvel dekket som papprøret (klossen) er betegnet med t. Fig. 5 shows a section through the attachment of a block to the tire according to e.g. US Patent No. 2,444,184. The block's mean diameter is denoted by D and the material thickness of both the cover and the cardboard tube (the block) is denoted by t.

Det vil lett innsees at overflaten av limfugen i dette tilfelle blir tilnærmet ' TT • D. t, og praktiske behov har vist at denne befestigelse visstnok er tilstrekkelig i et stort antall tilfeller, men at en altfor stor prosent av klossene løsner. It will be easily realized that the surface of the glue joint in this case is approximated ' TT • D. t, and practical needs have shown that this fastening is probably sufficient in a large number of cases, but that a far too large percentage of the blocks loosen.

Slikt har i hvert fall forekommet med det materiale som søkerenAt least this has happened with the material that the applicant

har anvendt.have applied.

Ettersom bruddene forekommer omkring limfugen ved at overflaten på dekket løsner og følger limfugen og klossen, kan man anse sammenføyningen som for svak. As the breaks occur around the glue joint when the surface of the tire loosens and follows the glue joint and the block, the joint can be considered too weak.

Fig. 6 viser befestigelsen av en gjennomgående kloss; Fig. 6 shows the fastening of a through block;

en variant av den delvis gjennomgående, i et hull anordnede kloss a variant of the partially continuous block arranged in a hole

som er vist i fransk patentskrift nr. 2.261.192. Limfugens overflate er herunder uttrykt: which is shown in French Patent Document No. 2,261,192. The surface of the adhesive joint is expressed below:

Den relativt moderate økning //t i forbindelse med krefter, som oppstår ved innfellingen av 2klossenden ( som i høy grad også øker styrken mot brudd) har vist seg i gi i praksis omkring 40% større styrke. The relatively moderate increase //t in connection with forces, which occurs when the 2-brick end is recessed (which also greatly increases the strength against breakage) has been shown to give in practice around 40% greater strength.

Fig. 7 viser befestigelsen ved søkerens engangspall ifølge oppfinnelsen, hvor klossens overkant innføres i et sirku-lært spor i platen ( dekket) hvorunder sporets dybde er større enn halvparten av dekkets tykkelse og det vil si større enn t Fig. 7 shows the attachment to the applicant's disposable pallet according to the invention, where the upper edge of the block is inserted into a circular groove in the plate (the tire) under which the depth of the groove is greater than half the thickness of the tire and that is greater than t

Limfugens overflate blir i dette tilfelle tilmærmet lik: In this case, the surface of the glue joint will be approximately equal to:

det vil si det dobbelte av tilfellet ifølge fig. 5. I praksis har det også vist seg at denne type har praktisk talt dobbelt styrke i forhold til den amerikanske typen, og at den ut fra an-vendelsessynspunkt er fullt sammenliknbar med og i mange tilfeller overlegen overfor den vanlig trepall. Dette gjelder i første rekke den pall som har såvel dekk som forsterkningslister innfestet . ved klossene på denne måten ,(fig. 1 og 2). that is, twice the case according to fig. 5. In practice, it has also been shown that this type has practically double the strength compared to the American type, and that from the point of view of use it is fully comparable to and in many cases superior to the ordinary wooden pallet. This primarily applies to pallets that have both tires and reinforcement strips attached. at the bricks in this way, (fig. 1 and 2).

Befestigelsen av klossene er altså avgjørende for om The fastening of the blocks is therefore decisive for whether

.pallen er praktisk anvendbar eller ikke og utførelsesformen iføl-ge fig. 7 har alene vist seg å svare til de krav som stilles. Utførelsen ifølge fig. 7 har utover denne større styrke også .the pallet is practically usable or not and the embodiment according to fig. 7 alone has been shown to meet the requirements. The embodiment according to fig. 7 also has greater strength beyond this

den tekniske effekt at noe lim ikke trenger ut på oversiden av dekket, og kleber seg til herdebordet, hvilket letter og gjør fremstillingen billigere. Ifølge oppfinnelsen har det vist seg hensiktsmessig å anordne et hull som på tegningen betegnes med 4 (fig. 7) som dels tjener til sentrumsstyring for det freseverktøy som lager sporet 5 på fig. 7, og dels tjener til avluftning av de inne i klossen dannete limdamper, kondens og liknende. the technical effect that some glue does not penetrate the upper side of the tire, and sticks to the curing table, which facilitates and makes production cheaper. According to the invention, it has proved appropriate to arrange a hole which is denoted by 4 in the drawing (fig. 7) which partly serves as a center control for the milling tool which makes the groove 5 in fig. 7, and partly serves to vent the glue vapors, condensation and the like formed inside the block.

Ved utførelsesformen ifølge oppfinnelsen utføres altså innfestingssporet i form av et utfreset, sirkelrundt, jevnt bredt spor i platen, hvorunder dybden av sporet overstiger den halve tykkelsen av skiven. I dette spor/på enden av klossen eller på begge, anbringes bindemiddel (lim) hvoretter enden av papprøret innføres i sporet og limet herdes. In the embodiment according to the invention, the fastening groove is thus made in the form of a milled, circular, evenly wide groove in the plate, under which the depth of the groove exceeds half the thickness of the disc. In this groove/on the end of the block or on both, a binder (glue) is placed, after which the end of the cardboard tube is introduced into the groove and the glue hardens.

Den på denne måten utførte pall har vist seg i ligge meget betydelig over de tidligere konstruksjoner hva angår styrke, og dette gjelder spesielt når såvel dekket som de underliggende lister festes til klossene på denne måten. The pallet made in this way has proven to be significantly superior to the previous constructions in terms of strength, and this applies especially when both the deck and the underlying strips are attached to the blocks in this way.

Den ekstra tekniske effekt som er oppnådd ifølge oppfinnelsen ved beskyttelsen mot lekasje av lim i retning mot her-dingsbordet, som gjør det mulig å øke produksjonshastigheten, The additional technical effect achieved according to the invention by the protection against leakage of glue in the direction of the curing table, which makes it possible to increase the production speed,

til trots for at utfresingen av et spor i prinsippet er en mere innviklet prosedyre enn, som tidligere, i utstanse gjennomgående hull. despite the fact that the milling of a groove is in principle a more complicated procedure than, as previously, punched through holes.

Fordelene med lastepallen ifølge oppfinnelsen er følge-lig mindre vekt og lavere pris og dessuten sikrere håndtering. Den er dessuten utført av et materiale som direkte kan males The advantages of the loading pallet according to the invention are consequently less weight and lower price and, moreover, safer handling. It is also made of a material that can be painted directly

for å gjenvinne fibermaterialet. Det absolutte fravær av spiker, splinter og liknende elementer er herunder en meget stor fordel. to recover the fiber material. The absolute absence of nails, splinters and similar elements is a very big advantage.

Den frigjør også store mengder verdifullt virke for andre formål. Det kan nevnes at antallet kasserte lastepaller av konvensjonell type innen en enda større bedrift for tiden på et år kan gå opp . til over 100.000. It also frees up large amounts of valuable timber for other purposes. It can be mentioned that the number of discarded conventional type pallets within an even larger company can currently increase in a year. to over 100,000.
