Description
Anordning til sponløs oppdeling i lengde av baneformede skumstofflegemer Device for chipless division in length of web-shaped foam bodies
Denne oppfinnelse vedrører en anordning til sponløs oppdeling av kontinuerlig fremstilte, baneformede skumstofflegemer av termoplastiske skumkunststoffer ved hjelp av elektrisk oppvarm-bare skjæreorganer. This invention relates to a device for chipless division of continuously produced, web-shaped foam bodies of thermoplastic foam plastics by means of electrically heatable cutting means.
Det er kjent å skjære baneformede skumkunststoffer, f. eks. av styrolpolymerisater, med opphetede tråder. Trådene opp-hetes til en temperatur over plastmaterialets smeltetemperatur og føres så gjennom skumstofflegemene i en retning som forløper lodd-rett på deres lengdeakse. Som regel består skjæreinnretningene av en bøyle, hvis bøylearmer er forsynt med holdeinnretninger for skjæretråden som strekker seg fra den ene bøylearm til den andre. Under skjæringen av skumstofflegemene kan både skjæreinnretningen festes på en bordplate og skumstofflegemet beveges, og også skjæretråden føres mot det faststående skjæregods. It is known to cut web-shaped foam plastics, e.g. of styrene polymers, with heated threads. The threads are heated to a temperature above the melting temperature of the plastic material and are then passed through the foam bodies in a direction that runs perpendicular to their longitudinal axis. As a rule, the cutting devices consist of a hoop, whose hoop arms are provided with holding devices for the cutting wire which extends from one hoop arm to the other. During the cutting of the foam material bodies, both the cutting device can be attached to a table top and the foam material body can be moved, and the cutting wire can also be guided towards the stationary material to be cut.
Til oppdeling av kontinuerlig fremstilte baner som på grunn av sin tykkelse eller krav til snittkvalitet ikke lar seg avskjære med stasjonære innretninger, som stanser e.l., anvendes uten unntagelse såkalte medløpende sager. Disse sager akselereres syklisk fra stillingen i den endeløse banes bevegelsesretning, til saginnretningen har nådd den samme hurtighet som banen som skal skjæres. Deretter følger skjæringen med en sirkelsag tilsvarende en sledeføring med egendrift som utføres på tvers av bevegelsesret-ningen av den kontinuerlig bevegede bane. Etter skjæringen må skjæreinnretningen beveges tilbake til utgangsstillingen mot banens bevegelsesretning. For the division of continuously manufactured webs which, due to their thickness or requirements for cut quality, cannot be cut with stationary devices, such as punches etc., so-called continuous saws are used without exception. These saws are accelerated cyclically from the position in the direction of movement of the endless web, until the saw device has reached the same speed as the web to be cut. Then follows the cutting with a circular saw corresponding to a self-propelled sled guide which is carried out across the direction of movement of the continuously moving path. After cutting, the cutting device must be moved back to the starting position against the direction of movement of the web.
Akselerering og nedbremsing -av skjæreinnretningens bevegede masser krever imidlertid betydelig kraftforbruk, slik at man i alminnelighet må ha et utvendig rammestativ og en synkroni-sert egendrift i lengderetningen. Hvis skumstoffene produseres med liten utstøtningshastighet på båndanlegget og den fremstilte, bane består av et belastningsdyktig materiale, kan medføringen av skjæreinnretningen skje ved fastklemming av samme på den bevegede bane. Dette fører allikevel mange ganger til unøyaktigheter i oppdelingen og har utover dette ikke vist seg å være økonomisk, Acceleration and deceleration - of the moving masses of the cutting device, however, require considerable power consumption, so that you generally have to have an external frame stand and a synchronized self-drive in the longitudinal direction. If the foam materials are produced with a low ejection speed on the belt plant and the produced web consists of a load-bearing material, the entrainment of the cutting device can take place by clamping it onto the moving web. However, this often leads to inaccuracies in the division and, beyond this, has not proven to be economical,
da produksjonskapasiteten ved moderne skumanlegg bare kan utnyttes for en tredjedels vedkommende. as the production capacity of modern foam plants can only be utilized for one third.
Med hensyn til det vanlige plåtemål på 0,5 m x 1 m ogWith regard to the usual plate size of 0.5 m x 1 m and
en av skumanlegget levert banebredde på 1 må skumstoffbanene hittil adskilles i en ytterligere arbeidsoperasjon ved hjelp av en stasjonær sirkelsag før oppdelingen. Dermed øker også forbru-ket av maskiner ved den etterfølgende konfeksjonering og stabling. Dessuten frigjøres spenningene i skumstoffet ved oppdeling av de på denne måte forberedte baner, slik at det kan oppstå vanskelig-heter i det nedre råtetthetsområde med hensyn til rettlinjet og rettvinklet forløp av de baneformede skumstofflegemer. one of the foam systems delivered with a web width of 1, the foam webs have to be separated in a further work operation using a stationary circular saw before the division. This also increases the consumption of machines during the subsequent packaging and stacking. Furthermore, the stresses in the foam material are released by dividing the webs prepared in this way, so that difficulties can arise in the lower raw density range with regard to the rectilinear and right-angled course of the web-shaped foam bodies.
Oppfinnelsens hensikt var derfor å gjøre oppdelingen av baneformede legemer av skumplast mer økonomisk, dvs. å muliggjøre oppnåelse av platemål på 1 m x 0,5 m og"derunder ved en eneste skjæreoperasjon og tillike å utnytte fullstendig den av skumanlegget bestemte produksjonshastighet. The purpose of the invention was therefore to make the division of web-shaped bodies of foam plastic more economical, i.e. to make it possible to achieve plate dimensions of 1 m x 0.5 m and "below" in a single cutting operation and at the same time to make full use of the production rate determined by the foam plant.
Ifølge oppfinnelsen oppnås denne hensikt ved en anordning av den innledningsvis angitte art ved at skjæreorganene er festet mellom to i avstand fra hverandre anordnede, synkront om lederuller drevne, endeløse transportkjeder og at under transportkjedenes hhv. skjæreorganenes arbeidsseksjon er det anordnet et stasjonært påleggsbord for de baneformede skumstofflegemer som danner en spiss vinkel med arbeidsseksjonen og i området mellom lederullene,hvor skjæreoperasjonen foregår, når nesten helt hen til skjæreorganene. According to the invention, this purpose is achieved by a device of the kind indicated at the outset in that the cutting members are fixed between two arranged at a distance from each other, driven synchronously around guide rollers, endless transport chains and that under the transport chains' respective the working section of the cutting means, a stationary support table is arranged for the web-shaped foam bodies which form an acute angle with the working section and in the area between the guide rollers, where the cutting operation takes place, reaches almost all the way to the cutting means.
Ved hjelp av disse forholdsregler kan skumstoffbaner med en bredde på 1 m selv ved produksjonshastigheter på 40 m/min. og derover deles opp i nesten så korte stykker man måtte ønske. Anordningen utmerker seg spesielt ved enkel oppbygning og er yt-terst ufølsom overfor forstyrrelser. Den enkle og lettholdte anordning av de omløpende skjæreorganer tillater rene og nøyaktige kutt i tett rekkefølge. With the help of these precautions, foam webs with a width of 1 m even at production speeds of 40 m/min. and above that is divided into almost as short pieces as you wish. The device is particularly distinguished by its simple structure and is extremely insensitive to disturbances. The simple and easy-to-maintain arrangement of the revolving cutting means allows clean and precise cuts in close succession.

Oppfinnelsen skal forklares nærmere under henvisning til et utførelseseksempel som er vist på tegningene, hvor: Fig. 1 er et skjematisk sideriss av anordningen, fig. 2 viser et tverrsnitt av anordningen ifølge fig. 1. The invention will be explained in more detail with reference to an embodiment shown in the drawings, where: Fig. 1 is a schematic side view of the device, fig. 2 shows a cross-section of the device according to fig. 1.
Hoveddelen av anordningen danner de dreibart i lågereThe main part of the device they form rotatably in lower
3 mellom sidevanger 4 anordnede lederuller 1,2. På hver forside av de to ruller 1 og 2 er det i en bestemt avstand anordnet kjedehjul 5 som er i inngrep med de to omløpende transportkjeder 6. 3 between side rails 4 arranged guide rollers 1,2. On each front of the two rollers 1 and 2 there is a sprocket 5 arranged at a certain distance, which engages with the two revolving transport chains 6.
Kjedeleddene er på yttersiden utformet som bærelaskerOn the outside, the chain links are designed as load carriers
7, på hvilke det er festet elektrisk ikke ledende mellomstykker 8 og på disse ledende bøyler 9. De ytre ender, av bøylene 9 glir i de to kontaktlister 10 som er fast forbundet med sidevangene 4, men er elektrisk isolert ved hjelp av et isoleringssjikt 11. Mellom to overfor hverandre liggende bøyler er det innspent med fjær 13 belastede skjæreorganer 12, f.eks. glødetråder. 7, on which are attached electrically non-conductive spacers 8 and on these conductive hoops 9. The outer ends of the hoops 9 slide in the two contact strips 10 which are firmly connected to the side walls 4, but are electrically isolated by means of an insulating layer 11 Between two hoops lying opposite each other, spring-loaded cutting means 12, e.g. filaments.
Sammai med avstivere 14 danner de to sidevanger 4 en stiv enhet som på et rammestativ 16 er lagret svingbart om et svingc-punkt 15 og ved hjelp av klemelementer 17 forskyvbar i transport-retningen av skumstofflegemer 21. Rammestativet 16 bærer dessuten flere drevne ruller 22 og et påleggsbord . 18, som i området mellom .lederullene 1 og 2 er ført helt nær til skjæreorganene 12 og danner en spiss vinkel med transportkjedenes 6 hhv. skjæreorganenes 12 arbeidsseksjon. I lederullens 1 påleggsområde er det stasjonære påleggsbord utformet dobbeltvegget og den flate som vender mot skumstofflegemet 21, har gjennombrudd. Med 20 er betegnet en til-førselsledning til et luftkammer 19. Together with stiffeners 14, the two side members 4 form a rigid unit which is stored on a frame stand 16 so that it can be pivoted about a pivot point 15 and, with the help of clamping elements 17, displaceable in the direction of transport of foam bodies 21. The frame stand 16 also carries several driven rollers 22 and a cold cuts table. 18, which in the area between the guide rollers 1 and 2 is brought very close to the cutting members 12 and forms an acute angle with the transport chains 6 or the cutting members' 12 working section. In the application area of the conductor roll 1, the stationary application table is double-walled and the surface facing the foam body 21 has a breakthrough. 20 denotes a supply line to an air chamber 19.
Det endeløse skumstofflegeme 21 tilføres anordningen med det stasjonære påleggsbord 18. Lederullen 1, som med en inn-stillbar kraft ligger på skumstofflegemet 21, dreier seg som følge av friksjon med skumstofflegemet 21 med en omkretshastighet som svarer til skumstofflegemets hastighet. Da delesirkeldiameteren åv de fire kjedehjul 5 på begge sider av rullene 1 og 2 er nøyak-tid lik rullediameteren, beveger de to transportkjeder 6 på begge sider av rullene 1 og 2 seg likeledes med skumstofflegemenes hastighet, og med transportkjedene beveger seg også de på disse fes-. tede mellomstykker 8, bøylene 9 og skjæreorganene 12 som løper med i de to kjeders plan. Kjedenes hhv. skjæreorganenes arbeidsseksjon danner med påleggingsbordet 18 en spiss vinkel hvis stør-relser er bestemt av forholdet mellom banens hastighet og skjæreorganenes skjærehastighet. The endless foam material body 21 is supplied to the device with the stationary application table 18. The guide roller 1, which rests on the foam material body 21 with an adjustable force, rotates as a result of friction with the foam material body 21 with a peripheral speed that corresponds to the speed of the foam material body. As the pitch circle diameter of the four sprockets 5 on both sides of the rollers 1 and 2 is exactly equal to the roller diameter, the two transport chains 6 on both sides of the rollers 1 and 2 move equally with the speed of the foam bodies, and with the transport chains also those on these fez-. ted intermediate pieces 8, the hoops 9 and the cutting members 12 which run along the plane of the two chains. The chains' respective the working section of the cutting members forms with the application table 18 an acute angle whose dimensions are determined by the ratio between the speed of the path and the cutting speed of the cutting members.
Kontaktlistene 10 som er under likespenning, er anbragt slik at skjæreorganet 12 etter avrullingen fra rullen 1 gjennom-strømmes så lenge av elektrisk strøm til det har nådd påleggings-bordets 18 nivå. I dette område av skjæreanlegget utføres det ter- miske snitt med dét elektrisk oppvarmede skjæreorgan 12, som utfø-rer en relativbevegelse med konstant hastighet vinkelrett på skum-stof f legemet 21, hvor hastigheten er omtrent 40 ganger mindre enn The contact strips 10, which are under direct voltage, are arranged so that the cutting member 12, after unrolling from the roll 1, is flowed through by electric current until it has reached the level of the application table 18. In this area of the cutting system, the thermal cut is performed with the electrically heated cutting device 12, which performs a relative movement at a constant speed perpendicular to the foam body 21, where the speed is approximately 40 times less than
det baneformede skumstofflegemes hastighet. De avskårne skum-stoffdeler faller ned på en rullebane 22 som har egendrift og som fører delene bort til en stableinnretning. Skulle en avskåret plate bli hengende mellom to skjæreorganer, vil den senere presses bort av lederullen 2, dvs. den vil presses mekanisk ned gjennom skjæreorganene. the velocity of the web-shaped foam body. The cut foam fabric parts fall onto a runway 22 which is self-propelled and which takes the parts away to a stacking device. Should a cut plate become suspended between two cutting means, it will later be pushed away by the guide roller 2, i.e. it will be mechanically pressed down through the cutting means.
Trykkraften fra rullen 1 og dermed drivkraften for de omløpende transportkjeder hhv. skjæreorganer kan reguleres ved forskyvning av sidevangene 4 i forhold til svingepunktet 15 ved hjelp av klemelementene 17 og således varieres innenfor vide gren-ser. The pressure force from roller 1 and thus the driving force for the revolving transport chains or cutting means can be regulated by displacing the side walls 4 in relation to the pivot point 15 by means of the clamping elements 17 and thus varied within wide limits.
For å holde friksjonen på det stasjonære påleggingsbord 18 i rullens 1 område minst mulig føres trykkluft gjennom lednin-gen 20 inn i kammeret 19, hvorfra luften gjennom perforeringer strømmer oppover og løfter skumstofflegemene noe og danner et luft-sjikt som gjør fremmatningen lettere. In order to keep the friction on the stationary application table 18 in the area of the roll 1 as low as possible, compressed air is fed through the line 20 into the chamber 19, from where the air flows upwards through perforations and lifts the foam bodies somewhat and forms an air layer that makes feeding easier.
