HIHNAMATERIAALI KULJETUSHIHNOJA VARTENBELT MATERIAL FOR CONVEYOR BELTS
Keksinnön kohteena on patenttivaatimuksen 1 johdanto-osassa määritelty hihnamateriaali.The invention relates to a belt material as defined in the preamble of claim 1.
5 Kuljetushihnoja valmistetaan muun muassa käyt tämällä ei-kudottuja huopakankaita, joilla on mahdollisimman pieni venyvyys ja mahdollisesti tietty elastisuus, jotta estetään kuljetushihnan venyminen sitä käytettäessä ja tästä johtuva kiristämisen tarve.5 Conveyor belts are manufactured, inter alia, by using non-woven felt fabrics with the lowest possible elongation and possibly some elasticity, in order to prevent the conveyor belt from stretching during use and the consequent need for tightening.
10 Ongelmana hihnassa on siihen helposti syntyvät staattiset varaukset, ts. sillä tavoin kuin on tunnettua van der Graff generaattorista. Tämä toiminta on erityisen ei-toivottua kuljetettaessa herkkiä osia kuten esim. elektronisia osia.10 The problem with the belt is the static charges that easily build up in it, i.e. as is known from a van der Graff generator. This operation is particularly undesirable when transporting sensitive components such as electronic components.
15 Ennestään on tunnettua käsitellä huopakankaita antistaattisesti niin, että huopaan sisällytetään johtavia kuituja mukaanluettuna synteettisiä kuituja sisältäviä materiaaleja estämään varautumista.It is previously known to treat felt fabrics antistatically by incorporating conductive fibers, including synthetic fiber-containing materials, into the felt to prevent charging.
Patenttijulkaisussa DE 2016403 esitetään huo-20 van staattisten varausten estämiseksi käytettäväksi aluskankaana tuftattuja huopia ja neulottuja tekstiili-kankaita, joihin kuuluu säie- tai kuitumaisia lankoja kuitusekoituksesta, jossa on metallikuituja tai metal-lisoituja kuituja.DE 2016403 discloses tufted blankets and knitted textile fabrics comprising filament or fibrous yarns from a fiber blend with metallic fibers or metallized fibers for use as a backing fabric to prevent static charges.
25 Patentissa DE 1917587 kuvataan metallin, edul lisesti teräskuitujen, lisäämistä erilaisista kuitumaisista materiaaleista koostuvaan laminaattiin.DE 1917587 describes the addition of a metal, preferably steel fibers, to a laminate of different fibrous materials.
Levysoittimien levylautasten staattisten varausten estämiseksi patentissa DE 2457542 esitetään 30 metallikuitujen, erityisesti teräskuitujen, käyttöä levylautasen peittävässä huovassa.In order to prevent static charges on the discs of record players, DE 2457542 discloses the use of metal fibers, in particular steel fibers, in the felt covering the disc.
Julkaisussa "Textile Institute and Industry", voi.7, 1972, s.199 kuvataan johtavia kankaita tehtynä kuitumatosta ja sisältäen metallikuituja käytettäväksi 35 suodatustarkoituksissa."Textile Institute and Industry", Vol. 7, 1972, p.199, describes conductive fabrics made of nonwoven mat and containing metal fibers for use in filtration purposes.
Julkaisusta DE-FZ "Textilveredelung" 17, 1982, Nr.6, s. 260-263 on tullut tunnetuksi, että kupa- 2 86894 risuoloilla käsiteltyjä, johtavia polyakryylinitriili-kuituja voidan laittaa huopiin, jotka soveltuvat anti-staattisiksi suojapukuihin, suodattimiin, mattoihin ja myös sisustusmateriaaleiksi.From DE-FZ "Textilveredelung" 17, 1982, No. 6, pp. 260-263, it has become known that conductive polyacrylonitrile fibers treated with copper salts can be applied to blankets suitable as antistatic protective suits, filters, mats. and also as decoration materials.
5 Tunnetussa tekniikassa käytettäessä kuitumat- toa ei kohdisteta erityisiä vaatimuksia lineaarisen venymisen kestolle ja täten ne eivät ole sopivia kulje-tushihnoiksi.In the prior art, the use of nonwoven mat is not subject to special requirements for the duration of linear elongation and is therefore not suitable as conveyor belts.
Julkaisussa DE 17 50 073 kuvataan voimansiir-10 tohihnaa varustettuna hihnarungon rakenteella, joka vähentää hihnan pituusvenymää, ja jossa hihnan sisään on järjestetty venymättömiä nauhoja tai lankoja.DE 17 50 073 describes a transmission belt 10 provided with a structure of the belt body which reduces the longitudinal elongation of the belt and in which non-stretchable strips or wires are arranged inside the belt.
Julkaisusta DE-GM 83 34 233 on tunnettu kuituja päällipuolelle asettamalla antistaattiseksi tehty 15 pituussuunnassa elastinen käyttöhihna, jossa pääasiassa kumista muodostuva hihna on päällystetty metallisoi-duilla kuiduilla.DE-GM 83 34 233 discloses a longitudinally elastic drive belt made antistatic on the upper side of the fibers, in which the belt consisting mainly of rubber is coated with metallized fibers.
Nauhan pituusvenymän vähentämiseksi kudosvah-visteiset kuljetushihnat ovat tunnettuja julkaisusta 20 DE-28 42 837. Siihen kuuluu joukko olennaisesti yh- desuuntaisia tekstiililankoja ja vähintään yksi näihin neulomalla yhdistetty kerros katkokuituja ja sekä nämä sisäänsäsulkeva elastomeerista polymeerihartsia oleva matriisi, jossa katkokuidut ovat keskenään huovutettu. 25 Tähän nauhaan ei kuitenkaan kuulu mitään antistaattista järjestelyä ja sen vuoksi se varautuu käytön aikana.To reduce the elongation of the strip, fabric-reinforced conveyor belts are known from 20 DE-28 42 837. It comprises a plurality of substantially parallel textile yarns and at least one layer of staple fibers connected by knitting, and these enclosing elastomeric polymer resin matrix with staple fibers. 25 However, this tape does not include any antistatic arrangement and therefore charges during use.
Menetelmä em nauhan valmistamiseksi on esitetty julkaisussa DE 32 31 119, jossa katkokuituhuopaan on kummallekin puolelle on neulottu alhaisen venymän teks-30 tiililankoja.A method for producing this strip is disclosed in DE 32 31 119, in which low-stretch textile bricks are knitted on both sides of the staple fiber felt.
Varausten välttämiseksi on jo ehdotettu kul-jetushihnoja, joissa on sideaineita tai pinnoitemate-riaaleja, joihin on lisätty johtavaa materiaalia, tavallisesti hiilimustaa tai metallipölyä. Epäedullisesti 35 tämä johtaa aina tummiin kuljetushihnoihin, kun taas monissa sovellutuksissa, kuten elektroniikassa ja elintarviketeollisuudessa, vaaleat hihnat ovat haluttavia.To avoid charges, conveyor belts have already been proposed with binders or coating materials to which a conductive material, usually carbon black or metal dust, has been added. Disadvantage 35 this always results in dark conveyor belts, while in many applications such as electronics and the food industry, light belts are desirable.
86894 386894 3
Lisäongelma muodostui tummien nauhojen hiilimustaa käytettäessä siten, että esiintyi kuljetettavan tavaran likaantumista johtuen hiilimustasta, mikä käyttäytyminen vaikeuttaa tai tekee mahdottomaksi näiden hihnojen 5 käyttämisen elektroniikkateollisuudessa.An additional problem arose when using carbon black for dark strips, with the contamination of the goods being transported due to carbon black, which behavior makes it difficult or impossible to use these belts 5 in the electronics industry.
Tunnetut hihnat ovat joko liian monimutkaisia valmistaa tai epäedullisia johtuen liian nopeasta pinnan kulumisesta. Ongelma paheni synteettisten kuitujen käytön lisäännyttyä kuitujen omatessa edullisia ominai-10 suuksia pituusvakioiduissa kuljetushihnoissa, joilla on lisääntynyt varautuvuustaipumus.Known belts are either too complicated to manufacture or disadvantageous due to too rapid surface wear. The problem was exacerbated by the increased use of synthetic fibers, with the fibers having advantageous properties in length-stabilized conveyor belts with an increased tendency to charge.
Tämän keksinnön tarkoituksena on täten järjestää hihnamateriaali, jossa on huopakangas sideainei-neen, kuljetushihnoja varten sellaiseksi, että kulje-15 tushihnojen varautuminen voidaan välttää.It is therefore an object of the present invention to provide a belt material with a felt fabric with a binder for conveyor belts so that the conveyance of the conveyor belts can be avoided.
Keksinnön mukaiselle hihnamateriaalille on tunnusomaista se, mitä on esitetty patenttivaatimuksessa 1.The belt material according to the invention is characterized by what is stated in claim 1.
Keksinnön mukaisesti ongelma ratkaistaan hih-20 namateriaalilla kuljetushihnoja varten koostuen olennaisesti huopakankaasta ja sideaineesta, jossa huopa-kankaan kuituseokseen kuuluu noin 1-10 p-% sähköisesti johtavia metallipitoisia katkokuituja jaettuna hih-namateriaalin koko poikkileikkauspinta-alalle.According to the invention, the problem is solved with a belt material for conveyor belts consisting essentially of a felt fabric and a binder, wherein the fiber mixture of the felt fabric comprises about 1-10% by weight of electrically conductive metallic staple fibers divided over the entire cross-sectional area of the belt material.
25 Keksinnön edullisia sovellutukset ilmenevät epäitsenäisistä patenttivaatimuksista.Preferred embodiments of the invention appear from the dependent claims.
Huopakankaat voivat koostua hyvin eri tyyppisestä kuitumatosta, esim. neulotusta kuitumatosta, kuidut sekaisin olevasta kuitumatosta jne.Felt fabrics can consist of very different types of nonwoven, e.g. knitted nonwoven, fibers mixed nonwoven, etc.
30 Huopakankaan kuitusekoitukseen voi kuulua synteettisiä ja/tai luonnon ja/tai puolisynteettisiä kuituja, kuten esim. polyesteriä, polyamidia, polypro-pyleeniä, polyakryyliä, puuvillaa, kookospähkinää ja villakuitua tai vastaavaa.The fiber blend of the felt fabric may include synthetic and / or natural and / or semi-synthetic fibers, such as polyester, polyamide, polypropylene, polyacrylic, cotton, coconut, and wool fiber, or the like.
35 Erityisen edullista on, jos hihnaan kuuluu yksi tai useampia synteettistä ja/tai luonnon ja/tai puolisynteettistä kuitua olevia korkean vetolujuuden ja 4 86894 alhaisen venymän lankoja, säikeitä, kankaita tai poimutettuja kankaita. Sopivia kuituja ovat esimerkiksi polyesteri, polyamidi, polypropyleeni, villa, polyara-midi, lasi ja keraamiset kuidut tai näiden yhdistelmät.It is particularly preferred that the belt comprises one or more high tensile and low elongation yarns, threads, fabrics or corrugated fabrics of synthetic and / or natural and / or semi-synthetic fibers. Suitable fibers include, for example, polyester, polyamide, polypropylene, wool, polyaramide, glass, and ceramic fibers, or combinations thereof.
5 Sähköisesti johtavissa kuiduissa voi olla ainakin yksi metalli tai alkuainehiili. Esimerkiksi on sopivaa käyttää teräs tai kuparikuituja tässä tarkoituksessa, mutta myös metallisoituja kuten hopeapinnoi-tettuja kuparikuituja voidaan käyttää. Tässä hiilellä 10 tarkoitetaan johtavia hiilimuunnoksia kuten grafiit-tikiteitä.5 Electrically conductive fibers may contain at least one metal or elemental carbon. For example, it is suitable to use steel or copper fibers for this purpose, but metallized such as silver-plated copper fibers can also be used. Here, carbon 10 refers to conductive carbon transformations such as graphite tics.
Edullisessa sovellutuksessa teräskuitujen tiitteri on 0,8-18 ja edullisesti 3-10 dtex ja kuitupituus on 20-80 mm. Edullisesti ei-kudotun kankaan pin-15 taresistanssi jännitteellä 100 V on 102 - 108 ja edullisesti 104 - 106 Ohmia.In a preferred embodiment, the titer of the steel fibers is 0.8-18 and preferably 3-10 dtex and the fiber length is 20-80 mm. Preferably, the tensile resistance of the non-woven fabric pin-15 at 100 V is 102 to 108 and preferably 104 to 106 Ohms.

20 Johtavaan huopakankaaseen kuljetushihnoiksi kuuluu edullisesti mekaanisesti neulottu synteettinen kuitumainen kuitumatto sisältäen johtavia kuituja ja sideainetta, jolla kuitumatto on kyllästetty. Huopakan-kaan valmistuksessa, joka voi vaihtoehtoisesti sisältää 25 yhden tai useamman kankaan tai laskostetun kankaan, kuitumaiseen kuitumattoon sekoitetaan johtavia kuituja, mekaanisesti kovetettu kuitumatto sitten kyllästetään sideaineella ja sitten kuivataan lämpötilassa 100°C.The conductive felt fabric conveyor belts preferably include a mechanically knitted synthetic fibrous nonwoven mat comprising conductive fibers and a binder with which the nonwoven mat is impregnated. In the manufacture of a felt fabric, which may alternatively include one or more fabrics or pleated fabrics, conductive fibers are mixed into the fibrous nonwoven mat, the mechanically cured nonwoven mat is then impregnated with a binder, and then dried at 100 ° C.
Huopakankaan kuitusekoitus voi sisältää syn-30 teettisiä ja/tai luonnon ja/tai puolisynteettisiä kuituja. Sopivia synteettisiä kuituja ovat esim. polyeste-rikuidut, polypropaleenikuidut ja näiden sekoitukset, erityisesti johtuen näiden korkeasta stabiilisuudesta ja edullisesta hinnasta.The fiber blend of the felt fabric may include synthetic and / or natural and / or semi-synthetic fibers. Suitable synthetic fibers are, for example, polyester fibers, polypropylene fibers and mixtures thereof, in particular due to their high stability and low cost.
35 Erityisen edullisia sähköisesti johtavia kui tuja ovat ne, joissa on ainakin yhtä hyvin johtavaa ja taipuisaa metallia, kuten kuparia, rautaa, alumiinia 86894 5 tai johtavalla metallilla päällystettyjä kuituja tai alkuainehiiltä.Particularly preferred electrically conductive fibers are those having at least as well a conductive and flexible metal such as copper, iron, aluminum 86894 5 or conductive metal coated fibers or elemental carbon.
Edullisia sideaineita ovat nitriili-butadiee-ni-kumi ja/tai styreeni-butadieeni-kumi-lateksi· Side-5 aineina on esim. mahdollista käyttää vesiliukoisia nitriili-butadieeni-kumia, styreeni-butadieeni-kumi- lateksia tai liuotinliukoisia sideaineita, kuten polyuretaani polyvinyylikloridi, polyakrylaatti tai näiden seoksia. Kuidun ja sideaineen suhde on edullisesti 10 välillä 1:2 - 2:1 ja erityisen edullisesti 1:1 painosta laskettuna.Preferred binders are nitrile-butadiene-rubber and / or styrene-butadiene-rubber-latex.
