Menetelmä ja kone kerrostettujen kohokuvioitujen arkkien valmistamiseksiMethod and machine for producing laminated embossed sheets
Esillä olevan keksinnön kohteena on pakotetuista selluloosatuotteis-5 ta, erityisesti imukykyisestä paperista, tehtyjen kerrostettujen arkkien valmistusmenetelmä, ja kone tämän menetelmän toteuttamista varten.The present invention relates to a process for making laminated sheets made from forced cellulose products, in particular absorbent paper, and to a machine for carrying out this process.
US-julkaisun 3 867 225 perusteella tunnetaan servietteinä, pöytäliinoina jne. käytettäviksi tarkoitettujen pakotetuista selluloosatuotteista tehtyjen kerrostettujen arkkien valmistusmenetelmä.US 3,867,225 discloses a method of manufacturing laminated sheets made from forced cellulose products for use as napkins, tablecloths, etc.
10 Tämä menetelmä käsittää kahden imupaperiarkin erillisen pakotuk sen kohoumakuviolla, jonka korkeus on 0,25 - 1,25 mm ja tiheys 3-20 ko-houmaa/cm2.This method involves separate embossing of two sheets of absorbent paper with an embossing pattern having a height of 0.25 to 1.25 mm and a density of 3 to 20 coats / cm 2.
Pakotus suoritetaan pakotuslaiteryhmän avulla, joka käsittää ku-misylinterin ja uurretun metallisylinterin. Yhteen osa-arkkiin levitetään liimaa ja 15 se liitetään toiseen osa-arkkiin "sisäkkäisen" liitännän avulla käyttäen liitossylin-teriä, joka on asetettu uurretun sylinterin suuntaisesti, kohdistaen suuruusluokkaa 900 - 1 000 kg/juoksumetri oleva paine. Tämä liitossylinteri voi käsittää metallisylinterin päällystettynä ohuella kumikerroksella, jonka kovuus on 90 shore A. Tällaisessa laitteessa uurrettu metallisylinteri asettaa kerrostetun arkin tuki-20 kosketukseen kumilla päällystetyn Iiitossylinterin kanssa saaden siten aikaan kumin muodonmuutoksen. Tämä muodonmuutos synnyttää tällöin haitallisia kohoumia kerrostetun arkin pinnassa.The compression is performed by means of a group of compression devices comprising a rubber cylinder and a ribbed metal cylinder. Adhesive is applied to one part sheet and bonded to another part by means of a "nested" connection, using connecting cylinders disposed in the direction of the ribbed cylinder at a pressure of the order of 900 to 1000 kg / meter. This joint cylinder may comprise a metal cylinder coated with a thin layer of rubber having a hardness of 90 shore A. In such a device, the grooved metal cylinder puts the laminated sheet support 20 into contact with the rubber coated joint cylinder, thereby causing a deformation of the rubber. This deformation then causes undesirable protrusions on the surface of the layered sheet.
Tämä kuvioiden kääntyminen ylösalaisin vähentää haitallisesti pehmeyttä ja säännöllisyyttä tällä tavoin valmistetussa tuotteessa. Lisäksi kumisylin-:·. 25 teriin kohdistettu paine hävittää liimauskohtia johtaen siten liiman kulkeutumi seen arkin poikki ja liitossylinterin tahriintumiseen.This inversion of the patterns adversely reduces the softness and regularity of the product thus produced. In addition, the rubber liner: ·. The pressure exerted on the blades destroys the gluing sites, thereby leading to the adhesive moving across the sheet and smearing the bonding cylinder.
Edellä mainitussa julkaisussa esitetään kylläkin mahdollisuus käyttää pinnaltaan sileää ilman päällystystä olevaa metallisylinteriä liitossylinterinä, mutta tämän ratkaisun katsotaan kuitenkin sisältävän tiettyjä haittoja, sillä se saa ai-30 kaan muodonmuutoksen hävittämällä uurretun sylinterin kohoumat.While the above-mentioned publication discloses the possibility of using a smooth surface uncoated metal cylinder as a joining cylinder, this solution is considered to have certain drawbacks as it causes a deformation by eliminating the ribs of the grooved cylinder.

Esillä olevan keksinnön tarkoituksena on siten tarjota käyttöön menetelmä ja kone, joiden avulla vältetään alalla aikaisemmin esiintyneet haitat.It is therefore an object of the present invention to provide a method and a machine for avoiding the drawbacks of the prior art.
Tämä tarkoitus saavutetaan menetelmällä kerrostettujen kohokuvioitujen arkkien valmistamiseksi, joka menetelmä käsittää ensimmäisen ja toisen 35 osa-arkin erillisen pakottamisen ensimmäisen ja toisen pakotuslaitteen avulla, jotka kumpikin käsittävät kumisylinterin ja uurretun sylinterin, joka sisältää ko- 2 111612 houmakuvion, jonka korkeus on 0,3 - 2 mm ja tiheys 3-20 kohoumaa/cm2, sideaineen ainakin osittaisen levittämisen yhteen osa-arkkiin muodostettujen kohoumien kärkiosaan ja molempien osa-arkkien liittämisen yhteen liitossylinterin avulla, joka on asetettu uurretun sylinterin suuntaisesti, niin että niiden ko-5 houmat tulevat sisäkkäin, jolloin liitossylinteri on tehty metallista tai kovuudeltaan vastaavanlaisesta materiaalista ja että se on kallistettavissa sylinterien kanssa yhdensuuntaisen akselin suhteen, jolle on tunnusomaista, että liitossylinteriä pidetään vastevälineitä vasten 0,01 - 0,1 mm:n välillä olevalla etäisyydellä uurretusta sylinteristä; ja koneella, joka käsittää ensimmäisen ja toisen pakotuslait-10 teen ja yhden pakotuslaitteen uurrettuun sylinteriin liitetyn liitossylinterin molempien aikaisemmin pakotettujen osa-arkkien yhteenliittämistä varten, jolloin liitos-sylinteri on tehty metallista tai muusta kovuudeltaan vastaavanlaisesta materiaalista ja on kallistettavissa sylinterien kanssa yhdensuuntaisen akselin suhteen, jolle on puolestaan tunnusomaista, että laite käsittää säädettävän vasteen, joka 15 mahdollistaa liitossylinterin pitämisen tietyllä etäisyydellä uurretusta sylinteristä.This object is achieved by a method of making layered embossed sheets, the method comprising separately forcing the first and second 35 sub-sheets by means of a first and a second forcing device, each comprising a rubber cylinder and a ribbed cylinder having a size 2 mm and a density of 3 to 20 protrusions / cm 2, at least partially applying the binder to the tip portion of the protrusions formed in one sub-sheet and joining the two sub-sheets together by a connecting cylinder disposed in the direction of the ribbed cylinder the connecting cylinder is made of metal or a material of similar hardness and is inclined with respect to an axis parallel to the cylinders, characterized in that the connecting cylinder is held against the abutment means at a distance of 0.01 to 0.1 mm the blades; and a machine comprising a first and a second mandrel 10 and a single mandrel for joining the two previously forced sub-sheets of a junction cylinder connected to the ribbed cylinder, the junction cylinder being made of metal or other material of similar hardness and inclined relative to the cylinders; is further characterized in that the device comprises an adjustable stop which allows the connecting cylinder to be held at a certain distance from the grooved cylinder.
Liitossylinterin suositeltavimpana materiaalina on teräs, mutta muitakin kovuudeltaan vastaavanlaisia materiaaleja voidaan käyttää.Steel is the preferred material for the connection cylinder, but other materials of similar hardness may be used.
Keksinnön ensimmäisen sovellutusmuodon mukaisesti liitossylinterin pinta on sileä.According to a first embodiment of the invention, the surface of the connecting cylinder is smooth.
20 Keksinnön erään toisen sovellutusmuodon mukaisesti liitossylinteri on varustettu pinnallaan olevilla kohoumilla ja se liikkuu tietyssä vaiheessa uurretun sylinterin suhteen, niin että molempien osa-arkkien yhteenlukituksen varmistavat näiden sylinterien vastaavien kohoumien kärkiosat.According to another embodiment of the invention, the coupling cylinder is provided with protrusions on its surface and moves at a certain point with respect to the ribbed cylinder so that the end portions of the respective protuberances of these cylinders ensure the interconnection of the two sub-sheets.
Esillä olevan keksinnön muut ominaisuudet ja edut käyvät havainnol-25 lisemmin ilmi seuraavasta selostuksesta oheisiin piirustuksiin viitaten, joissa: kuvio 1 esittää sivukuvantoa keksinnön mukaisen menetelmän toteuttamista varten tarkoitetusta koneesta; kuvio 2 esittää osittaista leikkauskuvantoa koneesta, joka sallii kahden pakotetun osa-arkin liittämisen yhteen, liitossylinterin ollessa myös uurrettu; 30 kuvio 3 esittää osittaista leikkauskuvantoa aikaisemmin tunnetusta laitteesta; kuvio 4 esittää osittaista leikkauskuvantoa kerrostetusta arkista sen kokoonpanon aikana pinnaltaan sileän liitossylinterin avulla; kuvio 5 esittää osittaista leikkauskuvantoa arkista sen kokoonpanon 35 aikana uurretun liitossylinterin avulla.Other features and advantages of the present invention will become more apparent from the following description with reference to the accompanying drawings, in which: Figure 1 is a side view of a machine for carrying out the method of the invention; Fig. 2 is a partial sectional view of a machine allowing two forced sub-sheets to be joined together with the joint cylinder also grooved; Figure 3 is a partial sectional view of a prior art device; Fig. 4 is a partial sectional view of a layered sheet during its assembly by means of a smooth-surface connecting cylinder; Fig. 5 is a partial sectional view of the sheet during its assembly 35 with a grooved connecting cylinder.

Kone käsittää ensimmäisen laiteyhdistelmän 1,11, joka sallii sellu-loosamateriaalista tehdyn arkin 10 pakottamisen metallisylinterin 11 pinnalla olevien kaiverrusten ansiosta, sylinterin 11 ollessa kiertävässä tukikosketukses-sa kumisylinterin 1 kanssa, johon arkki 10 kulkee. Uurretun sylinterin kohouma-5 kuviota käytetään sopivimmin hankaussovellutuksissa. Näiden kohoumien korkeus on suuruusluokkaa 0,3 - 2 mm ja niiden tiheys on 3 - 20 kohoumaa/cm2. Pakotuksen jälkeen tulokseksi saatu arkki 103 sisältää kohoumat 102. Arkki 103 asetetaan sitten vastakkain toisen pakotetun osa-arkin 203 kanssa. Tämä arkki 203 tehdään selluloosamateriaaliarkista 20, joka kulkee kumisylinterillä 4. Esite-10 tyssä luonteeltaan rajoittamattomassa esimerkissä lopullinen arkki 20 valmistetaan liittämällä yhteen kaksi yksinkertaista osa-arkkia. Kumisylinteri 4 on tuki-kosketuksessa arkin 20 kanssa toisen uurretun sylinterin 2 kaiverruksia pitkin kohoumat 202 sisältävän pakotetun osa-arkin 203 aikaansaamiseksi. Tämä toinen osa-arkki 203 liitetään yhteen ensimmäisen osa-arkin 10 kanssa pitäen nä-15 mä arkit tangentiaalisessa kosketuksessa ja tietyssä asennossa kohoumien suhteen toisen uurretun sylinterin 2 ja teräksestä tehdyn uurretun tai sileän lii-tossylinterin 5 välissä.The machine comprises a first assembly of devices 1.11 which allows the sheet 10 made of cellulosic material to be forced by engraving on the surface of the metal cylinder 11, the cylinder 11 being in rotating support contact with the rubber cylinder 1 to which the sheet 10 passes. The embossed cylinder protrusion-5 pattern is preferably used in abrasive applications. These protrusions have a height of the order of 0.3 to 2 mm and a density of 3 to 20 protrusions / cm 2. After embossing, the resulting sheet 103 includes protrusions 102. The sheet 103 is then placed face-to-face with the second forced sub-sheet 203. This sheet 203 is made of a sheet of cellulose material 20 passing through a rubber cylinder 4. In the non-limiting example of Brochure 10, the final sheet 20 is made by joining together two simple sub-sheets. The rubber cylinder 4 is in contact with the sheet 20 in order to provide a forced sub-sheet 203 including projections 202 of the second grooved cylinder 2. This second sub-sheet 203 is joined to the first sub-sheet 10, keeping the sheets in tangential contact and in a certain position with respect to the protrusions between the second ribbed cylinder 2 and the steel ribbed or smooth joint cylinder 5.
Ennen näiden kahden osa-arkin saattamista keskinäiseen kosketukseen ja niiden liittämistä yhteen levitetään yhden osa-arkin, tässä tapauksessa 20 toisen arkin 203, ulkopinnalla oleviin kohoumiin 202 liimakohdat 60 liimauslait-teen 6 avulla. Tämä liimauslaite käsittää liimaa sisältävän säiliön 64, johon upotetaan ensimmäinen tela 61, joka tangentiaalisen kosketuksensa välityksellä toisen telan 62 kanssa levittää liimakalvon toiselle telalle 62. Tämä toinen tela 62, jonka kolmas tela 63 saa kiertoliikkeeseen, levittää liimakalvon tälle kolmannelle :1· 25 telalle 63, joka taas levittää liimakohdat sylinterin 2 kaiverrusten avulla pakotetun paperin sisältämiin kohoumiin.Prior to bringing the two sub-sheets into contact and joining them together, adhesive points 60 are applied to the projections 202 on the outer surface of one sub-sheet, in this case 20 of the second sheet 203, by means of a sizing device 6. This gluing device comprises an adhesive-containing container 64 into which is inserted a first roll 61 which, through its tangential contact with the second roll 62, spreads the adhesive film onto the second roll 62. This second roll 62 received by rotation of the third roll 63 distributes the adhesive film to this third roll , which again spreads the adhesive points to the protrusions contained in the forced paper by engraving of the cylinder 2.
Kuvio 4 esittää tuotetyyppiä, joka saadaan tulokseksi käyttämällä laitetta, joka käsittää pakotussylinteriin 2 liitetyn sileän liitossylinterin 5. Tässä tapauksessa ensimmäinen osa-arkki 103 asetetaan toisen osa-arkin 203 päälle 30 ilman ensimmäisen arkin 103 ulkopinnan 104 muodonmuutosta. Kun liitossylin-teri 5 on myös uurrettu (kuviot 2 ja 5), tulevat liitossylinterin 5 kohoumat 50 suoraan uurretun sylinterin 2 kohoumia vasten, jolloin syntyy kärkiliitäntä pienellä muodonmuutoksella 105 kohti pakotetun kokoonpannun arkin sisäosaa.Figure 4 illustrates the type of product obtained by using a device comprising a smooth connecting cylinder 5 connected to the compression cylinder 2. In this case, the first part sheet 103 is placed over the second part sheet 203 without deformation of the outer surface 104 of the first sheet 103. When the connecting cylinder 5 is also grooved (Figs. 2 and 5), the projections 50 of the connecting cylinder 5 are directly against the protrusions of the grooved cylinder 2, thereby providing a tip connection with a small deformation 105 towards the inside of the forced assembled sheet.
Näissä molemmissa tapauksissa riippumatta siitä, onko sylinteri sileä 35 vai uurrettu, liitossylinterin ulkoisen emäsuoran uurretun sylinterin 2 kohoumien kärkiosien muodostamasta emäsuorasta erottava etäisyys H on pidettävä va- i 4 111612 kiona arvossa 0,01 - 0,1 mm. Täksi arvoksi on sopivimmin valittava 0,05 mm ottaen huomioon sileän liitossylinterin valmistustoleranssi, joka on suunnilleen 0,01 mm.In both these cases, whether the cylinder is smooth 35 or ribbed, the separation distance H from the base line formed by the protuberances of the outer base straight groove cylinder 2 of the coupling cylinder must be kept as 4111612 cions between 0.01 and 0.1 mm. This value is preferably set at 0.05 mm, taking into account the manufacturing tolerance of the smooth connecting cylinder, which is approximately 0.01 mm.
Käytännössä sylinteri 5 voi keinua kiertoakselinsa kanssa rinnakkai-5 sen akselin 51 ympäri ja sitä siirretään sylinterin 2 suunnassa sopivien väkivipu-jen 52 välityksellä. Etäisyys H säädetään säädettävien lukitsimien 53 avulla. Vä-kivipujen aikaansaama paine on käytännössä riittävä sylinterin 5 pitämiseksi tu-kikosketuksessa lukitsimia 53 vasten.In practice, the cylinder 5 can swing with its axis of rotation about its parallel axis 51 and is displaced in the direction of the cylinder 2 by means of suitable lever arms 52. The distance H is adjusted by means of adjustable latches 53. The pressure exerted by the veneers is practically sufficient to hold the cylinder 5 in contact with the latches 53.
Tällaisen koneen avulla voidaan välttää aikaisemmin tunnetuissa lait-10 teissä esiintyneet haitat, jotka on esitetty kuviossa 3, eli siis yhtäältä tulokseksi saadun kerrostetun arkin ulkopintaa kohti suuntautuvat muodonmuutokset 103' ja toisaalta koneen usein toistuvat pysäyttämiset puhdistusta varten liitossylinte-riä tahraavan liiman poistamiseksi.Such a machine avoids the disadvantages of the prior art apparatus 10 shown in FIG. 3, i.e., firstly, deformation 103 'towards the outer surface of the resulting laminate sheet and, on the other hand, frequent stops of the machine for cleaning to remove adhesive from the connecting cylinders.
Keksinnön mukaisen menetelmän tarjoamina muina etuina ovat osa-15 arkkien sangen hyvä liitäntä ja mahdollisuus osittaiseen liitäntään liitossylinterin 5 ja pakotussylinterin 2 kaiverruskuvioiden mukaisesti, jolloin tämä liitäntä ei tapahdu pakonalaisella tavalla pakotustuotteen koko pinnalla pakotussylinterin 29 välityksellä.Other advantages of the method according to the invention are the very good connection of the sub-15 sheets and the possibility of a partial connection according to the engraving patterns of the connecting cylinder 5 and the forcing cylinder 2, whereby this connection does not occur compulsorily over the surface of the forcing product.
Tällainen kone mahdollistaa siten pakotettujen arkkien valmistami-20 sen, jotka ovat paksumpia kuin tavanomaisten menetelmien avulla valmistetut arkit, joilla on maksimaalinen pehmeys ja joiden muoto pysyy säännöllisenä.Such a machine thus enables the production of forced sheets 20 which are thicker than sheets produced by conventional methods, having maximum softness and having a regular shape.
Lisäksi ylläpitämällä minimivälys liitossylinterin ja pakotussylinterin välillä vähennetään huomattavasti pakotussylinterin kulumista.In addition, by maintaining a minimum clearance between the connecting cylinder and the forced cylinder, wear on the forced cylinder is significantly reduced.
