5 TEKNIIKAN ALA5 FIELD OF TECHNOLOGY

Keksintö koskee paperipohjaista pakkausmateriaalia, sen valmistusta ja valmistuksessa käytettäviä välikappaleita sekä käyttöä. Materiaali soveltuu käytettäväksi erityisesti pak-kauspehmusteena.The invention relates to a paper-based packaging material, to its manufacture and to the spacers used in its manufacture, and to its use. The material is particularly suitable for use as a packaging cushion.

TEKNIIKAN TAUSTATECHNICAL BACKGROUND

On tunnettua valmistaa pakkauspehmustetta siten, että kolminkertaista paperia limitetään ja poimutetaan erityisen koneen avulla. Tämmöisen materiaalin suojaava vaikutus iskuja 15 tai puristusta vastaan ei kuitenkaan ole aina riittävä.It is known to manufacture packaging pads by overlapping and creasing triple paper by means of a special machine. However, the protective effect of such a material against shocks or compression is not always sufficient.

CH-julkaisusta 357 333 tunnetaan pakkausmateriaali, joka muodostuu kahdesta pinta-arkista ja näiden välisessä tilassa olevista H-muotoisista paperisista tai pahvisista kappaleista. Näin on muodostettu kennomainen rakenne. Pinta-arkit on 20 kiinnitetty välikerrokseen liimaamalla, mistä seuraa se että materiaali kokonaisuudessaan on hyvin jäykkää.CH publication 357 333 discloses a packaging material consisting of two surface sheets and H-shaped pieces of paper or cardboard in the space between them. Thus, a honeycomb structure is formed. The surface sheets 20 are attached to the intermediate layer by gluing, as a result of which the material as a whole is very rigid.

KEKSINNÖN KUVAUSDESCRIPTION OF THE INVENTION

Nyt on keksitty patenttivaatimuksen 1 mukainen paperipoh-25 jäinen materiaali, jolla on hyvä suojauskyky ja jonka valmistus ja käyttö on silti helppoa. Keksinnön eräitä edullisia sovellutuksia esitetään muissa vaatimuksissa.A paper-based material according to claim 1 has now been invented which has good protective properties and is still easy to manufacture and use. Some preferred embodiments of the invention are set out in the other claims.

Keksinnön mukaisessa materiaalissa on paperikennokerros ja ainakin sen toisella puolella pintapaperi. Materiaali voidaan 30 edullisesti valmistaa pituussuunnassa litistetystä paperi-kennoradasta ja pintapaperiradasta tai -radoista pakkausmateriaalin käyttöpaikalla.The material according to the invention has a paper cell layer and at least one side of which has a surface paper. The material can preferably be made from a longitudinally flattened paper cell web and a web or web of web paper at the point of use of the packaging material.

Seuraavassa keksinnön eräitä sovellutuksia selostetaan vielä yksityiskohtaisemmin.In the following, some embodiments of the invention are described in even more detail.

Kuvion 1 mukainen kennosto 1 muodostuu kuusikulmaisista paperikennoista. Se voidaan valmistaa siten, että paperi-ratoja liimataan päällekkäin yhteen pituussuuntaisin saumoin, näin saatu laminaatti leikataan halutun pituisiksi pätkiksi 10 joita sitten liimataan päällekkäin. Näin saadaan jatkuva, toisiaan vasten puristettujen kennorivien rata (kuvio 2), josta pituussuunnassa auki pingottamalla saadaan kuvion 1 mukainen rakenne.The honeycomb 1 according to Figure 1 consists of hexagonal paper cells. It can be made by gluing the paper webs on top of each other with longitudinal seams, the laminate thus obtained being cut into pieces 10 of the desired length, which are then glued on top of each other. In this way, a continuous web of rows of cells pressed against each other is obtained (Fig. 2), from which longitudinally open stretching, the structure according to Fig. 1 is obtained.

Kennoston 1 paksuus voi olla esimerkiksi 5...S mm. Kennon 15 halkaisija voi olla esimerkiksi 40 mm ja aukipingotetun rakenteen leveys esimerkiksi 450 mm, jolloin tarvittavan paperin leveys on noin 500...550 mm. Kennojen koko ja rakenteen paksuus voi luonnollisesti vaihdella aina materiaalilta vaadittavien ominaisuuksien mukaan. Kennojen muoto voi luon-20 nollisesti olla muunkinlainen kuin kuusikulmio, esimerkiksi neliö.The thickness of the cell 1 can be, for example, 5 ... S mm. The diameter of the cell 15 may be, for example, 40 mm and the width of the stretched structure, for example, 450 mm, whereby the width of the required paper is about 500 ... 550 mm. The size of the cells and the thickness of the structure can, of course, always vary according to the properties required of the material. The shape of the cells can naturally be other than a hexagon, for example a square.

Kennosto 1 voidaan valmistaa mistä tahansa käytettävissä olevasta paperista. Parhaiten se on esimerkiksi huokeaa Mg-tai Ug-voimapaperia tai sanomalehtipulkkipaperia. Pintapaino 25 voi olla esimerkiksi 30...70 g/m2. Haluttaessa voidaan käyttää myös esimerkiksi pehmopaperia.Honeycomb 1 can be made of any available paper. It is best, for example, cheap Mg or Ug kraft paper or newsprint. The basis weight 25 can be, for example, 30 ... 70 g / m 2. If desired, tissue paper, for example, can also be used.

: Kennoston 1 liimauksessa on syytä välttää sellaisten lii mojen käyttöä, jotka voivat haitata tuotteen mahdollista uu-delleenkuidutusta ja -paperiksivalmistusta. Tässä suhteessa 30 suositeltavimpia ovat yleensä vesiliukoiset liimat tai siistauksessa termoplastisesti muuttumattomat liimat.: When gluing honeycomb 1, the use of adhesives that may interfere with the possible re-fiberization and papermaking of the product should be avoided. In this respect, the most preferred are generally water-soluble adhesives or non-thermoplastic adhesives in deinking.

Kuviossa 3 esitetyssä valmistusmenetelmässä litistetty kennosto 1 on laatikossa 2, josta sitä vedetään ulos ja pingotetaan auki laitteiston 3 avulla. Laatikkoon voidaan pakata 35 kennorataa esimerkiksi määrä, josta saadaan 1...3 km aukive- dettyä rataa. Kennorata viedään saumauslaitteistoon 4. Siinä sen päälle ja alle asetetaan hieman sitä leveämmät yläpinta-paperi 5 ja alapintapaperi 6, jotka liitetään sivureunoistaan yhteen saumojen 7 avulla. Näin saadusta materiaaliradasta 3 95223 leikataan sitten halutun pituisia pätkiä 8 leikkauslaitteis-ton 9 avulla.In the manufacturing method shown in Fig. 3, the flattened cell 1 is in a box 2, from which it is pulled out and tensioned open by means of the apparatus 3. The box can be packed with 35 honeycomb tracks, for example, a quantity from which 1 ... 3 km of retracted track can be obtained. The honeycomb is introduced into the sealing apparatus 4. In it, a slightly wider top surface paper 5 and a bottom surface paper 6 are placed on top and under it, which are joined together at their side edges by means of seams 7. From the web of material 3 95223 thus obtained, pieces 8 of the desired length are then cut by means of a cutting device 9.

Kuvion 4 esittämässä sovellutuksessa käytetään pakkauspeh-musteen valmistukseen laitteistoa, jossa kennosto 1 ja vas-5 taava määrä yläpinta- 5 ja alapintapaperia 6 on pakattu yhteen, vaihdettavana kasettina toimivaan laatikkoon 10. Laatikosta 10 vedetään kennostoa 1 ja pintapaperia 5 ja 6 ulos siten, että niiden päät pystytään sitomaan yhteen sopivalla pujotusharavalla, joka on joko erillinen (kertakäyttöharava) 10 tai kiinteästi koneen yhteydessä toimiva (esim. johteilla liikkuva). Radan pää viedään pujotusharavan avulla saumaus-laitteiston 4 läpi. Rataa vetää vetotelapari 3 (ylätela ja alatela). Vetotelapareja voi olla kaksikin kappaletta, jolloin kennoston vetämiseen on oma ja pintapapereille oma 15 telapari. Telojen välisen kidan korkeuden määrää kennoston haluttu korkeus.In the embodiment shown in Fig. 4, an apparatus in which the honeycomb 1 and the corresponding amount of top surface 5 and bottom surface paper 6 are packed together in a box 10 acting as a replaceable cassette is used to make the packaging cushion. their ends can be tied together with a suitable threading rake, which is either a separate (disposable rake) 10 or fixedly connected to the machine (e.g. guided). The end of the track is passed through the sealing device 4 by means of a threading rake. The track is pulled by a pair of traction rollers 3 (upper roller and lower roller). There can be two pairs of drawing rollers, in which case there is a separate pair of rollers for drawing the honeycomb and a separate pair of rollers for surface papers. The height of the gap between the rollers is determined by the desired height of the honeycomb.

Kennosto 1 aukipingottuu vetojännityksen vaikutuksesta. Kennoston liukumista säätelee jarruna toimiva harjatela laatikon 10 suuaukolla.The cell 1 is stretched by the tensile stress. The sliding of the honeycomb is controlled by a brush roller acting as a brake at the mouth 10 of the box.

20 Kennosto pysyy suunnassaan reuna ohjainten avulla. Samanai kaisesti rata myös kapenee aukipingotuksen johdosta.20 The honeycomb is maintained in its direction by the edge guides. At the same time, the track also narrows due to opening tension.

Mikäli rata vedetään yhdellä telaparilla, on käyttönä esimerkiksi pieni rumpumoottori. Mikäli taas telapareja on kaksi, käytetään parhaiten mekaanisia tehonsiirtoelimiä.If the track is pulled with one pair of rollers, a small drum motor is used, for example. If, on the other hand, there are two pairs of rollers, mechanical power transmission elements are best used.

25 Aukipingotuslaitteesta voi olla erilaisia versioita eri käyttäjien tarpeiden mukaan. Käyttäjät, joilla pakkaustarve on suuri, hyötyvät ohjelmoitavasta logiikasta, jolloin mm. erilaisten tuotteiden vaatimat pehmustetarpeet voidaan ohjelmoida koneeseen etukäteen. Kone voi tehdä tietyn kokoista 30 käärettä jatkuvasti ilman pakkaajan välitöntä läsnäoloa.25 There may be different versions of the stretcher according to the needs of different users. Users with a high need for compression benefit from programmable logic, which means that e.g. the padding needs required by different products can be programmed into the machine in advance. The machine can make 30 wraps of a certain size continuously without the immediate presence of a packer.

Pienemmillä pakkausmäärillä operoivat käyttäjät tulevat hyvin toimeen pelkällä jalkapedaalilla ja painonappitoimin-noilla, jolloin myös laitekustannukset jäävät pienemmiksi.Users who operate with smaller pack sizes get on well with the foot pedal and push-button functions alone, which also reduces equipment costs.

Voitaisiin käyttää myös siirrettävää laitteistoa siten, 35 että käyttäjä ajaisi sillä omissa tiloissaan suurehkon määrän tuotetta valmiiksi esim. levy- tai rullatavaraksi, ja kone siirtyisi tämän jälkeen seuraavalle käyttäjälle.The portable equipment could also be used in such a way that the user drives a large amount of the product in his own premises as finished goods, e.g. as sheet or roll goods, and the machine would then be transferred to the next user.

. Kuviot 5 ja 6 esittävät valmista materiaalia levynä. Ku vion 5 materiaalissa yläpintapaperin 5 reuna on taivutettu 4 95223 vasten alapintapaperia. Kuvion 6 materiaalissa taas molempien paperien reunat on taivutettu.. Figures 5 and 6 show the finished material as a sheet. In the material of Figure 5, the edge of the top surface paper 5 is bent 4 95223 against the bottom surface paper. In the material of Figure 6, on the other hand, the edges of both papers are bent.

Kuvio 6 esittää materiaalia rullatavarana.Figure 6 shows the material as a roll.

Saumaus suoritetaan parhaiten mekaanisesti esimerkiksi 5 stanssaamalla tai nuuttaamalla, jolloin tuotteen kierrätys-kelpoisuus säilyy mahdollisimman hyvänä. Toinen vaihtoehto on ompeleminen, johon voidaan käyttää kierrätystä haittaamatonta luonnonkuitulankaa. Myös sopivaa liimausta voidaan käyttää, kunhan liima vain tarttuu riittävän nopeasti eikä haittaa 10 mahdollista kierrätystä.The sealing is best performed mechanically, for example by stamping or grouting, whereby the recyclability of the product remains as good as possible. Another option is sewing, which can use non-recyclable natural fiber yarn. Appropriate gluing can also be used, as long as the glue only adheres quickly enough and does not interfere with 10 possible recycling.

Myös yläpinta- 5 ja alapintapaperina 6 voidaan käyttää periaatteessa mitä tahansa paperia. Parhaiten se on samaa materiaalia kuin kennosto 1. Pintapaperit voivat luonnollisesti olla eri laatuakin aina halutun käyttötarkoituksen mukaan. 15 Toinen paperi voi olla esimerkiksi ohuempaa, toisessa paperissa taas voi olla ulkopinnalla esimerkiksi painatusta. Erityisiin suojaustarkoituksiin voidaan käyttää myös halutulla tavalla päällystettyjä papereita.In principle, any paper can also be used as the upper surface 5 and the lower surface paper 6. It is best made of the same material as honeycomb 1. Naturally, the surface papers can be of different qualities, depending on the intended use. 15 For example, one paper may be thinner, while the other paper may have, for example, printed on the outer surface. Paper coated as desired can also be used for special protection purposes.

Kennosto voidaan myös kiinnittää pintapaperiin, jolloin 20 varmistetaan kennoston aukipysymistä. Erityisesti kiinnitys voidaan suorittaa saumakohdissa esimerkiksi liimaamalla tai läpiompelemalla.The honeycomb can also be attached to the surface paper, thus ensuring that the honeycomb remains open. In particular, the fastening can be carried out at the joints, for example by gluing or stitching.

Keksinnön mukainen materiaali soveltuu käytettäväksi erityisesti suojaavana pakkauspehmusteena tai kääreenä. Kennora-25 kenteella on suuri puristuslujuus, jolloin materiaalin suo- jaava vaikutus iskuja ja puristusta vastaan on hyvä. Lisäksi • se pystyy absorboimaan pieniä pintaa vasten painavia partik keleita ilman että partikkeli painaa sisäpuolella olevaa esinettä. Rutistettuihin materiaaleihin verrattuna saavutetaan 30 sama hyötypinta-ala ja -tilavuus huomattavasti vähemmällä materiaalilla. Materiaali voidaan helposti tehdä kierrätyskel-. poiseksi. Paperien laatu, kennojen koko ja kennorakenteen paksuus voidaan valita aina kunkin käyttötarkoituksen mukaan.The material according to the invention is particularly suitable for use as a protective packaging pad or wrapper. The Kennora-25 structure has a high compressive strength, which means that the material has a good protective effect against shocks and compression. In addition, • it is able to absorb small particles that weigh against the surface without the object pressing on the object inside. Compared to crumpled materials, the same useful surface area and volume is achieved with significantly less material. The material can be easily recycled. poiseksi. The quality of the papers, the size of the cells and the thickness of the cell structure can always be selected according to each application.
