Menetelmå massatavaran pakkaamiseksi suurpakkaukseen Forfarande for forpackning av massagods i en storforpackning 5Method for packing bulk goods in large packages Forfarande for forpackning av massagods i en storforpackning 5

Keksinnon kohteena on menetelmå massatavaran pakkaamiseksi suurpakkaukseen, jossa menetelmåsså (a) joustavasta materiaalista oleva tukirakenteella varustettu sisåpakkaus asetetaan alus-10 talle, (b) sisåpakkaus tåytetåån massatavaralla, jolloin tåyton aikana sisåpakkaus hakeutuu olennaisesti suuntaissårmion muotoon, 15 (c) sisåpakkaus ja alusta ympåroidåån muovimateriaalia olevalla ulkopakkauksella, jolloin muodostuu stabiili kuljetuspakkaus.The invention relates to a method for packaging bulk material in a large package, in which method (a) an inner package of flexible material with a support structure is placed on a tray, (b) the inner package is filled with bulk material, the filling outer package to form a stable transport package.

Massatavaran pakkaamiseen, varastointiin ja kuljettamiseen kåytetåån alustalla (yleenså lava) olevia laatikkopakkauksia tai muita jåykån rakenteen omaavia pakkauksia.Box packaging or other rigidly structured packaging on a pallet (usually a pallet) is used for packaging, storage and transport of bulk goods.

20 Laatikkopakkaukset muodostuvat aaltopahvilaatikoista. Aaltopahvilaatikko on yleenså varustettu sisåsåkillå. Tållainen pakkaus omaa tåytettynå nelikulmaisen muodon ja hyodyntåå nåin olien kuljetusalustan maksimaalisesti, vaikkakin pakkaus sellaisenaan on kallis.20 Boxes consist of corrugated boxes. The corrugated box is usually equipped with an inner bag. Such a package, when filled, has a rectangular shape and thus utilizes the transport platform to the maximum, although the package as such is expensive.

25 Suursåkkejå kåytetåån myos massatavaran pakkaamiseen, varastointiin ja kuljettamiseen. Suursåkki on laatikkopakkausta halvempi, mutta sen epåkohtana on sen pydreå muoto tåytettynå, jolloin se hyodyntåå kuljetusalustan epåedullisemmin kuin laatikko-. pakkaus.25 Large bags are also used for packing, storing and transporting bulk goods. The big bag is cheaper than a box package, but it has the disadvantage of its round shape when filled, which makes the utilization of the transport platform less favorable than that of a box. packaging.

30 Suomalaisessa patenttihakemuksessa n:o 921043 on esitetty menetelmå massatavaran pakkaamiseksi suurpakkaukseen ja massatavaralle tarkoitettu suurpakkaus, joka muodos tuu sisåpakkauksesta ja ulkopakkauksesta. Sisåpakkaus on taipuisasta materiaalista oleva 2 91954 sisåsåkki, joka massatavaralla tapahtuvan tåytdn ajaksi on asetettu alustalle, edullisesti ripustamalla tai tukemalla alustan ylåpuolelle. Ulkopakkaus on sisåpakkausta tiiviisti ympåroivå ja riittåvån stabiliteetin antava muovimateriaalia oleva ulkopakkaus. Ulkopakkaus on sisåpakkauksen ympåri kiristekalvonauhaa kietomalla muodostettu 5 ulkopakkaus. Ulkopakkaus voidaan muodostaa myos sisåpakkausta ympåroivåstå tåysleveåstå kiristekalvosta tai saumalla varustetusta tåysleveåstå kiristekalvosta. Ulkopakkaus voi olla myos sisåpakkausta ympåroivå kiriste- tai kutistehuppu tai kiriste- tai kutistesukka.30 Finnish patent application No. 921043 discloses a method for packaging bulk goods in a large package and a large package for bulk goods, which consists of an inner package and an outer package. The inner package is an inner bag of 2,91954 made of flexible material, which is placed on a base during filling with bulk goods, preferably by hanging or supporting above the base. The outer packaging is an outer packaging made of plastic material that tightly surrounds the inner packaging and provides sufficient stability. The outer package is an outer package 5 formed by wrapping a stretch film strip around the inner package. The outer package can also be formed from a full-width stretch film surrounding the inner package or from a full-width stretch film with a seam. The outer package can also be a tension or shrink hood or a tension or shrink sock surrounding the inner package.

10 Tåsså tunnetussa suurpakkauksessa kåytetåån erillistå tukirakennetta, jotta varmistu-taan siitå, ettå massatavaralla tapahtuvassa tåytosså sisåpakkaus såilyttåå olennaisesti suuntaissårmion muodon. Alustana voidaan kåyttåå standardin mukaisia kuormalavoja (esim. EUR-, FIN-kuormalavoja). Nåin voidaan yhdiståå laatikkopakkauksen maksi-maalinen tilankåytto ja joustopakkauksen edullinen hinta. Samalla voidaan kåytetyn 15 pakkauksen kierråtys hoitaa parem min, koska mitåån lajittelua ei vaadita, vaan joustopakkaus talteenotetaan sellaisenaan ja standardi kuormalava palautuu kiertoon. Laatikkopakkauksen ollessa kyseesså joudutaan erottamaan laatikko, sisasakki ja alusta ja talteenotto on hoidettava kolmen eri jåijestelmån kautta.10 In this known large package, a separate support structure is used to ensure that the bulk package retains substantially the shape of a parallelepiped in bulk filling. Standard pallets (eg EUR, FIN pallets) can be used as a platform. In this way, the maximum space utilization of the box packaging and the low price of the flexible packaging can be combined. At the same time, the recycling of the used package 15 can be better handled, because no sorting is required, but the flexible package is recovered as it is and the standard pallet is returned to circulation. In the case of a box package, the box, the inner bag and the base must be separated and the recovery must be carried out through three different systems.

20 FI-patenttihakemuksen n:o 921043 mukainen suurpakkaus ei sovellu erityisen hyvin sellaiselle massatavaralle, jonka sisåinen kitka on erittåin pieni.The large package according to FI patent application no. 921043 is not particularly well suited for bulk goods with very low internal friction.

Vaikka erittåin pienen sisåisen kitkan omaavaa massatavaraa pakattaessa i tse sisåpakkaus hakeekin suuntaissårmion muodon sisåpakkauksessa olevan tukirakenteensa 25 ansiosta, jåå pelkån sisåpakkauksen stabiliteetti usein vajavaiseksi jatkovaihetta, sisåpakkauksen ympåroimistå muovimateriaalia olevalla ulkopakkauksella, vårten ja : siten loppupakkauksen kåsittelyominaisuudet, esim. pinottavuus ja ryhdikkyys eivåt aina muodostu optimaalisiksi.Although the inner package retrieves the shape of a parallelepiped due to its support structure 25 when packing very low internal friction bulk material, .

30 Keksinnon pååmåårånå on aikaansaada menetelmå sellaisen massatavaran pakkaami-seksi joustopakkaukseen, jonka massatavaran sisåinen kitka on erittåin pieni.It is an object of the invention to provide a method for packaging a bulk article in a flexible package whose internal friction of the bulk article is very low.

li 3 91954li 3 91954

Keksinnon mukainen menetelmå massatavaran pakkaamiseksi suurpakkaukseen on tunnettu siitå, ettå (d) massatavaralla tåytettyyn sisåpakkaukseen aiheutetaan alipaine, jolloin sisåpakkaus 5 puristuu tiiviisti massatavaran ympårille, ja (e) alipaineinen massatavaralla tåytetty sisapakkaus ympåroidåån muovimateriaalia olevalla ulkopakkauksella.The method according to the invention for packaging bulk material in a large package is characterized in that (d) a vacuum is filled in the inner package filled with bulk material, whereby the inner package 5 is pressed tightly around the bulk material, and (e) the vacuum-filled inner package is surrounded by plastic packaging.

10 Keksinnon mukaisen menetelmån eras toinen edullinen suoritusmuoto on tunnettu siita, ettå (d) sisapakkaus asetetaan muottirakenteen sisåpuolelle, 15 (e) sisapakkaus tåytetaån massatavaralla, jolloin sisapakkaus hakeutuu olennaisesti suorasårmion muotoon muottirakenteen ympåroidesså sisåpakkausta, (f) massatavaralla taytettyyn sisapakkaukseen aiheutetaan alipaine, jolloin sisapakkaus puristuu tiiviisti massatavaran ympårille, 20 (g) muottirakenne poistetaan massatavaralla tåytetyn sisåpakkauksen ympårilta, jolloin alipaineinen massatavaralla taytetty sisapakkaus sailyttåå olennaisesti suorasarmion muotonsa, ja 25 (h) alipaineinen massatavaralla taytetty sisapakkaus ympåroidåan muovimateriaalia olevalla ulkopakkauksella.Another preferred embodiment of the method according to the invention is characterized in that (d) the inner package is placed inside the mold structure, (e) the inner package is filled with bulk material, presses tightly around the bulk material, the mold structure is removed from the bulk package-filled inner package, whereby the vacuum bulk-filled inner package retains substantially its rectangular shape, and 25 (h) vacuum-filled bulk-filled inner package.

Keksinnon perusoivalluksen mukaisesti sisapakkaukseen aikaansaadaan alipaine tåyton jålkeen ennen sisåpakkauksen sulkemista. Tålloin sisåpakkaus puristuu tiiviisti 30 massatavaran ympårille, ja sen johdosta sisåpakkauksen stabiliteetti kasvaa ja jatkovaihe voidaan tehdå helposti.According to the basic idea of the invention, a vacuum is created in the inner package after filling before the inner package is closed. In this case, the inner package is pressed tightly around the bulk material 30, and as a result, the stability of the inner package increases and the further step can be easily performed.

Kun sisåpakkaus on ympåroity muovimateriaalilla, joka asettuu tiiviisti sisåpakkausta vasten, on saatu aikaan stabiili kuljetuspakkaus. Suurpakkauksen stabiliteetti pysyy tålloin hyvånå, vaikka sisåpakkaukseen aiheutettu alipaine ajan myotå katoaisikin. Tålloin saavutetaan ainakin seuraavat konkreettiset edut tunnettuihin alipainepakkauksiin 5 verrattuna.When the inner package is surrounded by a plastic material that rests tightly against the inner package, a stable transport package is obtained. The stability of the large packaging then remains good, even if the vacuum caused to the inner packaging disappears over time. In this case, at least the following concrete advantages are achieved compared to the known vacuum packages 5.

Sisåpakkauksessa voidaan kåyttåå normaaleja polyolefiinirnuoveja, esim. poly-eteenejå, eikå tarvita kalliita barrierimuoveja, joiden kierråttåminen on lisåksi hankal aa.Normal polyolefin molds, e.g. polyethylene, can be used in the inner packaging, and expensive barrier plastics are not required, which are also difficult to recycle.

Jos kuljetuksen ja kåsittelyn aikana sisåpakkaukseen tulee pieni reikå, ei suurpakkauksen stabiliteetti tasta kårsi, koska sisåpakkausta ympåroivå muovimateriaali, edullisesti esikiristetty kiristekalvo, antaa tarvittavan stabiliteetin.If a small hole becomes in the inner package during transport and handling, the stability of the large package is not affected, because the plastic material surrounding the inner package, preferably a pre-tensioned stretch film, provides the required stability.

15 Keksinnon mukaisen menetelmån erååsså suoritusmuodossa voidaan kåyttåå erillistå ulkopuolista muottirakennetta. Tålloin on edullista, jos erillinen ulkopuolinen muottira-kenne on samankokoinen kuin kuljetusalusta, koska talloin sisåpakkaus asettuu tarkoin kuljetusalustan mittojen mukaisesti.In one embodiment of the method according to the invention, a separate external mold structure can be used. In this case, it is advantageous if the separate external mold structure is of the same size as the transport base, since in this case the inner package is precisely positioned according to the dimensions of the transport base.

20 Keksinnon mukaisessa menetelmåsså on oivallettu kåyttåå suurpakkausta, joka muodostuu taipuisasta halvasta materiaalista olevasta sisåpakkauksesta ja sitå ympå-roivåstå ulkopakkauksesta, joka antaa suurpakkaukselle riittåvån tukevuuden. Sisåpak-kauksen taipuisana materiaalina, jonka jåykkyys on suhteellisen alhainen, voidaan kåyttåå esim. muovikalvoja tai kankaita. Joustopakkaus ripustetaan tai tuetaan massata- 25 varan tåyton ajaksi sopivan alustan kuten esim. kuormauslavan ylåpuolelle. Massata-varalla tapahtuvan tåyton jålkeen sisåpakkaukseen aiheutetaan alipaine ja sisåpakkaus sidotaan alustaan esim. kiristekalvolla siten, ettå muodostuu tukeva kokonaisuus ts. suurpakkaus. Kiristekalvon leveys ei ole olennainen tekijå. Kiristekalvon leveys voi olla tavanomainen leveys kuten esim. n. 500 mm, mutta kiristekalvona voidaan kåyttåå 30 myos jopa koko sisåpakkauksen korkuista tåysimittaista kiristekalvoa. Kiristekalvon sijasta voidaan luonnollisesti kåyttåå myos kiristehuppua tai kutistehuppua.In the method according to the invention, it is realized to use a large package consisting of an inner package made of a flexible cheap material and an outer package surrounding it, which gives the large package sufficient strength. Plastic films or fabrics, for example, can be used as the flexible material of the inner package, which has a relatively low stiffness. The flexible package is hung or supported above a suitable platform, such as a pallet, during the filling of the bulk material. After filling with bulk material, a vacuum is applied to the inner package and the inner package is bonded to the substrate, e.g. with a stretch film, so that a sturdy whole is formed, i.e. a large package. The width of the stretch film is not a significant factor. The width of the stretch film can be a conventional width, such as about 500 mm, but a full-length stretch film of up to the height of the entire inner package can also be used as the stretch film. Instead of a tension film, a tension hood or a shrink hood can of course also be used.

li 5 91954li 5 91954

Keksinnon mukaiselle suurpakkaukselle on ominaista se, etta suurpakkauksen sisapak-kaus kestaå tåyttovaiheen asettamat rasitukset ja etta massatavaralla tåytetyn sisåpak-kauksen ympårysmitta ei oleellisesti kasva tayttovaiheen aikana. On huomattava, etta tåyton aikana sisåpakkaus saa hieman levita, ts. muuttaa muotoaan ja hakeutua 5 nelikulmaiseen muotoon, joka on sitten myohemmin helppo ympåroidå kiristekalvolla lopullisen suurpakkauksen aikaansaamiseksi.The large package according to the invention is characterized in that the inner package of the large package withstands the stresses imposed by the filling phase and that the circumference of the inner package filled with bulk material does not substantially increase during the filling phase. It should be noted that during filling, the inner package is allowed to spread slightly, i.e. to deform and apply to a rectangular shape, which is then later easily surrounded by a stretch film to obtain the final large package.

Keksinnon mukainen suurpakkaus mahdollistaa kåytettyjen joustopakkausmateriaalien uudelleen kierråttåmisen. Lisaksi suurpakkauksessa kåytetty kuormauslava voidaan 10 suurpakkauksen tyhjentåmisen jålkeen varastoida ja kåyttåå uudestaan.The large packaging according to the invention makes it possible to recycle used flexible packaging materials. In addition, the pallet used in the large package can be stored and reused after the large package has been emptied.

Keksinnon mukainen massatavaralla tåytetty suurpakkaus on riittåvån ryhdikås ja toimiva kokonaisuus, joka kestaå hyvin myos varastointia ja kuljetusta. Keksinnon mukaista suurpakkausta on helppo nostaa esim. varastoinnissa nostamalla suurpakkausta 15 trukin haarukoilla kuormauslavassa olevista aukoista.The bulk package according to the invention, filled with bulk goods, is a sufficiently upright and functional entity that can also withstand storage and transport well. The large package according to the invention is easy to lift, e.g. in storage, by lifting the large package with the forks of 15 trucks from the openings in the pallet.

Sisapakkaus, ulkopakkaus ja kuorma-alusta muodostavat kokonaisuuden, joka on helposti pinottavissa ja joka ei olennaisesti muuta muotoaan pinoamisen ja varastoinnin aikana.The inner package, the outer package and the pallet form an assembly which is easily stackable and which does not substantially change its shape during stacking and storage.

2020

Keksinnon eras merkittåvin etu on siinå, etta keksinnon mukainen suurpakkaus voidaan valmistaa tavallista suursåkkiå olennaisesti våhemmåstå materiaalimååråstå, koska varmuuskertoimen vaatimaa nostokykyå ei tarvita, kuten on asianlaita nostosilmukoilla varustetuissa suursåkeisså.One of the most significant advantages of the invention is that the large package according to the invention can be made of a substantially smaller amount of material than an ordinary large sack, because the lifting capacity required by the safety factor is not required, as is the case with large sacks with lifting loops.
