Description
DK 169290 B1DK 169290 B1
Opfindelsen angår en fremgangsmåde ved fremstilling af emballageemner til anvendelse som emballage for en eller flere genstande eller som mellemlæg mellem en ydre emballage og en eller flere genstande, hvilke emner består af fiberpulp 5 i et stort set jævntykt lag, formet med forhøjninger bestemt til at ligge an imod genstanden eller genstandene.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a method of producing packaging blanks for use as packaging for one or more articles or as interposers between outer packaging and one or more articles, which blanks consist of fiber pulp 5 in a substantially flat layer formed with elevations intended to lie against the object or objects.
Ved fremgangsmåder af denne art har det indtil nu været nødvendigt at ændre de støbeforme, hvormed emballageemnerne 10 fremstilles, hver gang der sker en ændring i udformningen af de genstande, som emballageemnerne skal anvendes til at emballere, f.eks. ved at indgå som mellemlæg mellem genstanden og en ydre emballage, ofte i form af en papkasse.In processes of this kind, it has hitherto been necessary to change the molds by which the packaging blanks 10 are manufactured each time there is a change in the design of the objects to be used for the packaging blanks, e.g. by interposing between the article and an outer packaging, often in the form of a cardboard box.
15 Ændringer af støbeformen er imidlertid en meget kostbar affære og kan kun forsvares økonomisk, dersom der skal fremstilles meget store serier. Det har derfor indtil nu været vanskeligt at finde frem til en metode til hensigtsmæssig emballering af genstande, hvis sider ikke er plane, f.eks.15 However, changes to the mold are a very costly affair and can only be financially defended if very large series are to be produced. So far, it has been difficult to find a method for the proper packaging of articles whose sides are not planar, e.g.
20 flasker, video-optagere, kameraer mv., og man har i mange tilfælde måttet ty til ret primitive løsninger, såsom anvendelse af løst fyld i form af skumplastelementer eller sammenkrøllet papir.20 bottles, video recorders, cameras, etc., and in many cases have had to resort to fairly primitive solutions, such as the use of loose fill in the form of foamed plastic elements or crumpled paper.
25 Det er på denne baggrund opfindelsens formål at anvise en fremgangsmåde af den indledningsvis angivne art, hvormed det på en rimeligt økonomisk måde er muligt at fremstille emballageemner til brug ved emballering af genstande med ikke-plane overflader, også når det drejer sig om relativt 30 små serier, og dette formål opnås ved en fremgangmåde, som ifølge opfindelsen er ejendommelig ved a) at der som udgangsmateriale anvendes emner af fiber-pulpmateriale, der er formet som et grundmateriale med et antal forhøjninger og deréfter tørret til 35 stivhed, og b) at de nævnte emner underkastes presning på en sådan DK 169290 B1 2 måde, at et antal af de nævnte forhøjninger nedpresses helt eller delvis på en sådan måde, at når en eller flere af de genstande, som emballageemnerne skal anvendes til at emballere, anbringes i berøring med 5 emnerne i områderne med helt eller delvis nedpressede forhøjninger vil genstanden eller genstanden samtidigt komme til anlæg imod og blive støttet af i det mindste nogle af de helt eller delvis nedpressede forhøjninger.Accordingly, it is the object of the invention to provide a method of the kind set out at the outset by which it is reasonably economically feasible to produce packaging blanks for use in the packaging of objects with non-planar surfaces, even in relatively 30 small series, and this object is achieved by a method which according to the invention is characterized by a) that as a starting material, blanks of fiber pulp material formed as a basic material having a number of elevations and then dried to stiffness are used, and b) said items being subjected to compression in such a manner that a number of said elevations are compressed in whole or in part in such a way that when one or more of the articles to be used for packaging the items are placed in touching the 5 items in the areas with fully or partially depressurized elevations will simultaneously reach the object or object im od and be supported by at least some of the fully or partially depressed elevations.
1010
Herved kan der til fremstilling af emnerne hele tiden anvendes den samme støbeform, nemlig svarende til udgangsmaterialets udformning, idet materialet først efter tørring til stivhed tilpasses efter de enkelte genstande, der skal embal-15 leres, hvad der kan ske med betydeligt mindre omkostninger, end hvad der kræves til at ændre støbeforme.In this way, the same mold can be used at all times to produce the articles, namely corresponding to the design of the starting material, the material, after drying to rigidity, being adapted to the individual articles to be packaged, which can happen at a considerably lower cost than what it takes to change molds.
Hensigtsmæssige udførelsesformer for fremgangsmåden, hvis virkninger vil fremgå af den efterfølgende specielle del af 20 nærværende beskrivelse, er angivet i underkravene.Appropriate embodiments of the method, the effects of which will become apparent from the following specific part of the present disclosure, are set forth in the subclaims.
Opfindelsen angår også et presseværktøj og/eller mod-pres-seværktøj til udøvelse af fremgangsmåden, og ifølge opfindelsen er dette værktøj ejendommeligt ved, at det omfatter 25 i det mindste a) en grundplade med fastgørelsesorganer, anbragt i et mønster svarende til det mønster, som forhøjningerne på de nævnte ark eller baner er anbragt i, og b) mindst ét presseorgan eller mod-presseorgan, der er 30 indrettet til at fastgøres til grundpladen ved hjælp af fastgørelsesorganerne og til at bearbejde den eller de i en tilsvarende position på udgangsmaterialet beliggende forhøjninger.The invention also relates to a pressing tool and / or pressing tool for carrying out the method, and according to the invention, this tool is characterized in that it comprises at least a) a base plate with fastening means, arranged in a pattern corresponding to the pattern, and (b) at least one pressing means or counter pressing means arranged to be attached to the base plate by means of the fastening means and to work the position (s) in a corresponding position on the starting material. elevations.
35 Opfindelsen skal følgende forklares nærmere under henvisning til tegningen, på hvilken DK 169290 B1 3 fig. 1 i perspektiv viser et eksempel på et udgangsmateriale til brug ved udøvelse af fremgangsmåden ifølge opfindelsen, 5 fig. 2 ligeledes i perspektiv viser det i fig. 1 viste udgangsmateriale efter bearbejdning ved fremgangsmåden ifølge opfindelsen, fig. 3 er et del-snit efter linien III-III i fig. 2, 10 fig. 4 ligeledes i perspektiv viser det i fig. 2 viste emballageemne med en genstand, der skal emballeres, anbragt støttende på emnet, 15 fig. 5 er et til fig. 3 svarende snit, og viser hvorledes den i fig. 4 viste genstand kan emballeres i en papkasse med to emballageemner ifølge fig. 4 som mellemlæg, fig. 6 i perspektiv viser en under-presseplade med et antal 20 under-presseklodser fastgjort til pladen, og fig. 7 er et snit svarende til linien VII-VII i fig. 6 og viser foruden den i fig. 6 viste under-presseplade også en over-presseplade med en dertil fastgjort over-presseklods, 25 samt det mellem de to presseplader anbragte emballageemne.The invention will be explained in greater detail with reference to the drawing, in which DK 169290 B1 3 FIG. 1 is a perspective view of an example of a starting material for use in the practice of the invention; FIG. 2 is also a perspective view illustrating in FIG. 1 after processing the process according to the invention, fig. 3 is a partial sectional view taken along line III-III of FIG. 2, 10 FIG. 4 is a perspective view of the device shown in FIG. 2 shows a packaging blank with an article to be packaged, supported on the blank, FIG. 5 is a view of FIG. 3, showing how the FIG. 4 can be packaged in a cardboard box with two packaging items according to FIG. 4 as an insert; FIG. 6 is a perspective view of a sub-press plate having a plurality of 20 sub-press blocks attached to the plate, and FIG. 7 is a section similar to line VII-VII of FIG. 6 and, in addition to the one shown in FIG. 6 also shows an over-press plate with an over-press pad attached thereto, as well as the packaging blank arranged between the two press plates.
Det i fig. 1 viste udgangsmateriale til brug ved udøvelse af fremgangsmåden ifølge opfindelsen består på i princippet kendt måde af 30 - et ark- eller baneformet grundmateriale 1 og et antal forhøjninger 2, som i det viste eksempel er udformet som afkortede kvadratiske pyramider, anbragt i et mønster af indbyrdes vinkelret krydsende rækker på grundmaterialet 1.The FIG. 1 for use in practicing the method according to the invention consists in principle known in principle of 30 - a sheet or web-shaped basic material 1 and a number of elevations 2, which in the example shown are designed as truncated square pyramids, arranged in a pattern of intersecting perpendicular rows on the base material 1.

Udgangsmaterialet 1,2 er på kendt måde fremstillet af fiber- DK 169290 B1 4 materiale, f.eks. ved aflejring af fibre fra en vælling eller "pulp" fremstillet af f.eks. plantefibermasse, især træmasse, eller papirmasse, herunder genbrugs-papirmasse, mod en af finmasket net bestående form, på hvis bagside 5 der opretholdes et undertryk, således at fibrene aflejres ved frafiltrering på formen. Efter denne aflejring fjernes udgangsmaterialet fra formen og tørres, indtil den bliver tør og stiv, og fremtræder derved med stort set de samme materialeegenskaber som de velkendte ægbakker af det samme 10 materiale, og har i lighed med disse stort set den samme vægtykkelse overalt, dvs. også i forhøjningerne 2.The starting material 1,2 is in a known manner made of fiber material, e.g. by depositing fibers from a swelling or "pulp" made of e.g. plant fiber pulp, especially wood pulp, or pulp, including recycled pulp, against a fine-mesh web, on the back of which a negative pressure is maintained, so that the fibers are deposited by filtering off the mold. After this deposition, the starting material is removed from the mold and dried until it becomes dry and rigid, thereby appearing with substantially the same material properties as the well-known egg trays of the same material, and, like these, having substantially the same wall thickness throughout, i.e. . also in the elevations 2.
Det i fig. 1 viste udgangsmateriale kan uden videre anvendes til emballeringsformål, f.eks. som mellemlæg mellem en pap-15 kasse og en heri emballeret genstand, forudsat at genstanden har samme form som papkassen, men med mindre dimensioner svarende til det mellemrum, der skal udfyldes af udgangsmaterialet.The FIG. 1 starting material can easily be used for packaging purposes, e.g. as an intermediate between a cardboard box and an article packaged therein, provided that the article has the same shape as the cardboard box, but with smaller dimensions corresponding to the space to be filled by the starting material.
20 Opfindelsen beskæftiger sig imidlertid med tilpasning af det i fig. 1 viste udgangsmateriale med henblik på emballering af genstande, der ikke er kasseformede, f.eks. runde flasker, video-kameraer mv., og dette opnås ved som vist i fig. 2 og 3 at ændre formen på nogle af forhøjningerne 2, 25 således at disse kan støtte den emballerede genstand på en hensigtsmæssig måde. Til dette formål er visse forhøjninger 2a nedpresset til langt under den halve højde under dannelse af en skålformet overside, mens andre forhøjninger 2b, beliggende på modsatte sider af forhøjningerne 2a, er nedpres-30 set til dannelse af mod hinanden vendende, buede sideflader, som ligger på den samme cirkulære cylinderflade som den buede overside af forhøjningerne 2a. Yderligere er forhøjninger 2c og 2d delvis nedpresset til dannelse af sammensatte flader, der sammen med de nedpressede flader på forhøjnin-35 gerne 2a og 2b danner et leje, hvori en cylindrisk genstand 3 kan hvile, jf. fig. 4 og 5. Som antydet i fig. 4 vil de DK 169290 B1 5 ikke-nedpressede forhøjninger 2c og 2d, der befinder sig ud for enderne af genstanden 3, forhindre denne i at glide på langs ud af det nævnte leje.However, the invention relates to the adaptation of the embodiment shown in FIG. 1 for packaging non-boxed articles, e.g. round bottles, video cameras, etc., and this is achieved by as shown in fig. 2 and 3 to change the shape of some of the elevations 2, 25 so as to support the packaged article in an appropriate manner. For this purpose, certain elevations 2a are depressed to well below half height to form a bowl-shaped upper surface, while other elevations 2b, located on opposite sides of elevations 2a, are depressurized to form facing, curved side surfaces which lies on the same circular cylinder surface as the curved upper side of the elevations 2a. Further, elevations 2c and 2d are partially depressed to form composite surfaces which, together with the depressed surfaces of elevations 2a and 2b, form a bed in which a cylindrical object 3 can rest, cf. 4 and 5. As indicated in FIG. 4, the non-depressed elevations 2c and 2d located at the ends of the object 3 will prevent it from sliding longitudinally out of said bearing.
5 Som antydet i fig. 5 kan genstanden 3 passende emballeres i en i afbrudt streg antydet papkasse 4 ved at udskære to stykker af passende størrelse og udstrækning af grundmaterialet 1 og anbringe genstanden 3 mellem disse inden i papkassen 4.5 As indicated in FIG. 5, the article 3 can conveniently be packaged in a broken cardboard box 4 indicated by cutting two pieces of suitable size and extension of the base material 1 and placing the article 3 between them within the cardboard box 4.

Fig. 6 og 7 viser en under-presseplade 5 og en over-pres-seplade 6, således som de fortrinsvis anvendes ved udøvelse af fremgangsmåden ifølge opfindelsen.FIG. 6 and 7 show an under-press plate 5 and an over-press plate 6, as they are preferably used in the practice of the method according to the invention.
15 Under-pressepladen 5 kan f.eks. være en stiv plade af stål eller aluminium, hvori der er boret ensartede huller 7 i et mønster svarende til det mønster, hvori forhøjningerne 2 og 2b-2d er anbragt, mens der i over-pressepladen 6, bestående f.eks. af det samme materiale som under-pressepladen 20 5, ligeledes er udformet huller 8 med samme form og i samme fordeling som hullerne 7 under-pressepladen 5.The sub-press plate 5 can e.g. be a rigid plate of steel or aluminum, in which uniform holes 7 are drilled in a pattern corresponding to the pattern in which the ridges 2 and 2b-2d are arranged, while in the overpressure plate 6 consisting e.g. of the same material as the under-pressing plate 20 5, holes 8 are also formed of the same shape and in the same distribution as the holes 7 the under-pressing plate 5.
Når der skal fremstilles emballeringsemner, der er tilpasset efter formen af den genstand, der skal emballeres, f.eks.When preparing packaging items adapted to the shape of the item to be packaged, e.g.
25 den i fig. 4 og 5 viste cylindriske genstand 3, fastgøres der på under-pressepladen 5 et antal under-presseklodser 9 og 9a-9d, hvoraf presseklodserne 9a-9d er udformet svarende til den ønskede form på forhøjningerne henholdsvis 2a-2d, mens under-presseklodser 9 kun anbringes i et antal - som 30 kan være lig med nul - svarende til hvad der kræves til styring af udgangsmaterialet 1,2 i den pågældende presse. Samtidigt forsynes over-pressepladen 6 med en eller flere over-presseklodser, i det viste eksempel kun en enkel over-presseklods 10, hvis form svarer til formen for den del af 35 den cylindriske genstand 3, der skal støttes af forhøjningerne 2a-2d. Samtlige presseklodser er fastgjort til de DK 169290 B1 6 pågældende presseplader ved hjælp af skruer 11.25 is the one shown in FIG. 4 and 5, a plurality of sub-press blocks 9 and 9a-9d are secured to the sub-press plate 5, the press blocks 9a-9d being formed in accordance with the desired shape of the elevations 2a-2d, respectively, while sub-press blocks 9 is placed only in a number - which may be equal to zero - equal to what is required to control the starting material 1,2 in the press concerned. At the same time, the overpressure plate 6 is provided with one or more overpressure blocks, in the example shown only a simple overpressure block 10, the shape of which corresponds to the shape of the part of the cylindrical object 3 to be supported by the elevations 2a-2d. All press blocks are attached to the relevant press plates by means of screws 11.
Under-presseklodserne kan som vist i fig. 7 være forsynet med pressefladedele 12 af gummi. Herved formindskes risikoen 5 forf at dele af de forhøjninger, der presses, rives i stykker under nedpresningen, og samtidigt optages eventuelle mindre variationer i vægtykkelsen i forhøjningerne, som ellers kunne føre til problemer, navnlig ved samtidig presning af flere emner ud fra ét og samme udgangsmaterialestykke.The underpressure blocks may be shown in FIG. 7 be provided with rubber pressing members 12. This reduces the risk of 5 parts of the elevations being pressed being torn during the depression, and at the same time any minor variations in the wall thickness of the elevations are taken up which could otherwise lead to problems, especially when simultaneously pressing several items from one and the same starting material piece.
1010
Presningen foretages helt enkelt på den måde, at et udgangsmateriale 1,2 som vist i fig. 1 anbringes oven på den i fig. 6 viste underpresseplade 5 på en sådan måde, at forhøjningerne 2 føres ned på under-presseklodserne 9 og 9a-9d.The pressing is simply done in such a way that a starting material 1,2 as shown in FIG. 1 is placed on top of the one shown in FIG. 6, in such a way that the elevations 2 are brought down on the underpressure blocks 9 and 9a-9d.
15 Derefter føres over-pressepladen 6 ned imod under-pressepla-den 5, hvorved over-presseklodsen 10 i samvirke med under-presseklodserne 9a-9d former de pågældende forhøjninger 2 til dannelse af de ønskede forhøjninger 2a-2d. Presningen kan eventuelt udføres under passende befugtning og tilførsel 20 af varme, f.eks. ved indblæsning af varm luft og/eller opvarmning af presseklodserne, idet materialets tilbøjelighed til efter presningen at ændre form henimod den oprindelige form herved formindskes betydeligt, således som det f.eks. er almindeligt kendt fra presning af beklædningsgenstande 25 af tekstilmateriale.The overpressure plate 6 is then brought down towards the underpressure plate 5, whereby the overpressure block 10, in cooperation with the underpressure blocks 9a-9d, forms the respective elevations 2 to form the desired elevations 2a-2d. The pressing may optionally be carried out under appropriate wetting and supply of heat, e.g. by blowing in hot air and / or heating the press blocks, the material's tendency to change after the pressing to the original shape is thereby significantly reduced, such as e.g. is commonly known from the pressing of garments 25 of textile material.
Når det drejer sig om mindre ændringer af formen på de oprindelige fremspring 2, kan presningen også foretages uden anvendelse af under-presseklodser, først og fremmest i de 30 tilfælde, hvor det drejer sig om en nedpresning af hele oversiden af de pågældende forhøjninger. Dersom den i fig.In the case of minor changes in the shape of the original projections 2, the pressing can also be carried out without the use of underpressure blocks, especially in the 30 cases where the entire upper surface of the raised projections is pressed down. If in FIG.
3 viste vinkel 13 mellem de modstående sidevægge i forhøjningerne 2 ligger i området fra 20° til 40°, har det vist sig, at der ved en sådan nedpresning dannes ••harmonikafolder" i 35 den øverste del af forhøjningen, uden at dennes styrke forringes i væsentlig grad. De hidtil foretagne forsøg har DK 169290 B1 7 antydet, at denne vinkel fortrinsvis bør være ca. 30°.3, between the opposite side walls of the elevations 2 is in the range of 20 ° to 40 °, it has been found that such a depression forms a "harmonic fold" in the upper part of the elevation without impairing its strength. In the experiments conducted so far, DK 169290 B1 7 has suggested that this angle should preferably be about 30 °.
Det i fig. 1 viste eksempel på et udgangsmateriale til brug ved udøvelse af fremgangsmåden ifølge opfindelsen har som 5 vist og nævnt et antal forhøjninger 2, formet som afkortede pyramider og anbragt i et mønster af indbyrdes vinkelrette rækker, men opfindelsen kan også udøves under anvendelse af udgangsmateriale, hvori forhøjningerne er udformet på anden måde og/eller anbragt i andre mønstre end her vist og omtalt.The FIG. 1, an example of a starting material for use in the practice of the invention has shown and mentioned a number of elevations 2, shaped as truncated pyramids and arranged in a pattern of mutually perpendicular rows, but the invention can also be practiced using starting material wherein the elevations are designed differently and / or arranged in patterns other than shown and discussed herein.
10 Med henblik på at gøre udgangsmaterialet så universelt anvendeligt som muligt foretrækkes det imidlertid, at forhøjningerne i det mindste er ensartede og anbragt i et regelmæssigt mønster, f.eks. som det viste eller i form af et "bikagemøn-ster*·, idet det herved gøres betydeligt lettere at tilpasse 15 de i fig. 6 og 7 viste presseværktøjer til fremstilling af emballageemner af forskellig form.However, in order to make the starting material as universally applicable as possible, it is preferred that the elevations are at least uniform and arranged in a regular pattern, e.g. as shown or in the form of a "honeycomb pattern", thereby making it considerably easier to adapt the pressing tools shown in Figures 6 and 7 to produce packaging items of various shapes.
Det er også muligt på ikke vist måde at nedpresse en eller flere forhøjninger fuldstændigt, dvs. at de ikke længere 20 udgør forhøjninger, men flugter med grundmaterialet. Herved kan det gøres muligt at anbringe etiketter og/eller tryk på de udfladede dele, eller også at give plads til en genstand, der skal emballeres,· eller dele af en sådan genstand - dog kun i de tilfælde, hvor det ikke kræves, at emballageemnet 25 skal beskytte genstanden mod stød.It is also possible, in a manner not shown, to depress one or more elevations completely, ie. that they no longer constitute elevations but flush with the base material. This makes it possible to place labels and / or print on the flattened parts, or also to make room for an item to be packaged, or parts of such an item - but only in cases where it is not required that the packaging blank 25 is intended to protect the article from impact.
Endelig er det også muligt - ligeledes på ikke vist mådeat nedpresse en eller flere forhøjninger således, at deres udvendige mål stort set svarer til de indvendige mål af en 30 eller flere af de øvrige forhøjninger. Herved kan to eller flere par forhøjninger anbringes oven på hinanden, dels til opnåelse af en sammenlåsning af de pågældende grundmaterialedele, dels til forøgelse af evnen til optagelse af stødenergi.Finally, it is also possible - also in a manner not shown - to depress one or more elevations so that their external dimensions correspond largely to the internal dimensions of one or more of the other elevations. Hereby two or more pairs of elevations can be placed one on top of the other, partly to obtain an interlocking of the basic material parts concerned and partly to increase the ability to absorb shock energy.
