Description

SVEISEANORDNING WELDING DEVICE

Denne oppfinnelse angår en sveiseanordning for å feste plastdeler på plastkonstruksjoner. This invention relates to a welding device for attaching plastic parts to plastic constructions.

Når plastkonstruksjoner slik som tanker og rør, inngår i sam-menhenger hvor de skal koples til, festes til eller ligge an mot andre konstruksjonselementer, er det ofte nødvendig å forsyne plaskonstruksjonene med tilleggsdeler, slik som rør-stusser, festeanordninger, støtteanordninger og andre plastdeler. When plastic constructions, such as tanks and pipes, are part of connections where they are to be connected to, attached to or abutted against other structural elements, it is often necessary to supply the plastic constructions with additional parts, such as pipe connectors, fastening devices, support devices and other plastic parts .

Ved masseproduksjon av tynnveggede plastkonstruksjoner, slik som drivstofftanker for kjøretøyer, anvendes automatiserte sveiseanordninger. Når eksempelvis en rørstuss skal festes på en drivstofftank med en kjent sveiseanordning, føres den ene flate av et oppvarmet metallstykke kalt et varmespeil, inn til fysisk kontakt med tankens overflate. Samtidig føres rør-stussen til kontakt med en annen varm flate som normalt er baksiden av varmespeilet. In the mass production of thin-walled plastic structures, such as fuel tanks for vehicles, automated welding devices are used. When, for example, a pipe connection is to be attached to a fuel tank with a known welding device, one surface of a heated piece of metal called a heat mirror is brought into physical contact with the surface of the tank. At the same time, the pipe end is brought into contact with another hot surface, which is normally the back of the heating mirror.

I kjente sveiseanordninger føres varmespeilet og plastdelen som skal sveises fast, av hver sin stempelsylinder som er rettet mot et felles treffpunkt, hvor plastdelen skal sveises fast til plastkonstruksjonen. Ved en sveisesyklus føres først varmespeilet til kontakt med plastkonstruksjonen, hvoretter plastdelen føres til kontakt med baksiden av varmespeilet. Når sveisetemperatur er nådd, trekkes plastdelen litt tilbake, hvoretter varmespeilet trekkes bort fra sveisesonen. Plastdelen føres så inn til kontakt med plastkonstruksjonen og holdes der til sveiseforbindelse er oppnådd. In known welding devices, the heat mirror and the plastic part to be welded are each guided by a piston cylinder which is directed towards a common meeting point, where the plastic part is to be welded to the plastic structure. During a welding cycle, the heat mirror is first brought into contact with the plastic structure, after which the plastic part is brought into contact with the back of the heat mirror. When the welding temperature is reached, the plastic part is pulled back a little, after which the heat mirror is pulled away from the welding zone. The plastic part is then introduced into contact with the plastic construction and held there until a welding connection is achieved.

En ulempe med kjente sveiseanordninger er at de krever stor A disadvantage of known welding devices is that they require a large

plass. En viktig årsak til dette er at stempelsylindrene som beveger henholdsvis plastdel og varmespeil, av plasshensyn må rettes mot sveisesonen med ulik vinkel. Plastdelen føres van-ligvis vinkelrett inn mot plastkonstruksjonens overflate, mens varmespeilet føres inn på skrå. Sveiseanordningen opp-tar dermed et relativt stort rom rundt den plastdel som sveises fast. Er det mange plastdeler som skal sveises fast innenfor et begrenset område på en plastkonstruksjon, er det på grunn av plassmangel nødvendig å anordne flere sveisesta-sjoner og forflytte plastkonstruksjonen fra stasjon til stasjon. Dette virker naturlig nok svært fordyrende. place. An important reason for this is that the piston cylinders which move the plastic part and the heat mirror, respectively, must be directed towards the welding zone at a different angle for reasons of space. The plastic part is usually inserted perpendicular to the surface of the plastic construction, while the heat mirror is inserted at an angle. The welding device thus occupies a relatively large space around the plastic part that is welded. If there are many plastic parts to be welded within a limited area on a plastic construction, due to lack of space it is necessary to arrange several welding stations and move the plastic construction from station to station. This naturally seems very expensive.

En annen ulempe med kjente sveiseanordninger er at når varmespeilet er i kontakt med plastkonstruksjonens overflate, må stempelsylinderen gjøres kraftløs. Hvis ikke presses varmespeilet inn i og kanskje helt igjennom plastveggen etter hvert som temperaturen stiger. Når plastdelen presses mot baksiden av det kraftløse varmespeil, overføres også en uønsket kraft til plastkonstruksjonen, og det kan oppstå skade. Another disadvantage of known welding devices is that when the heat mirror is in contact with the surface of the plastic structure, the piston cylinder must be rendered powerless. If not, the heat mirror is pressed into and perhaps completely through the plastic wall as the temperature rises. When the plastic part is pressed against the back of the powerless heat mirror, an unwanted force is also transferred to the plastic structure, and damage can occur.

Videre er det ofte slik at plastdelen har tykkere gods enn plastkonstruksjonen og krever mer varme. Oppvarming av plastdelen tar derfor lenger tid enn oppvarming av sveisesonen på plastkonstruksjonen. Ved kjente sveiseanordninger kan imid-lertid ikke plastdelen komme i kontakt med varmespeilet før dette er på plass og i kontakt med plastkonstruksjonen. Det er derfor et problem med kjente sveiseanordninger at plastkonstruksjonen skades ved at den tilføres for mye varme. Furthermore, it is often the case that the plastic part has thicker material than the plastic construction and requires more heat. Heating the plastic part therefore takes longer than heating the welding zone on the plastic construction. With known welding devices, however, the plastic part cannot come into contact with the heat mirror until this is in place and in contact with the plastic construction. It is therefore a problem with known welding devices that the plastic structure is damaged when too much heat is applied.

Formålet med oppfinnelsen er å skaffe en forbedret sveiseanordning for å feste plastdeler til plastkonstruksjoner. The purpose of the invention is to provide an improved welding device for attaching plastic parts to plastic constructions.

Formålet oppnås ved trekk som angitt i etterfølgende patent- The purpose is achieved by features as stated in the subsequent patent

krav. claim.

Oppfinnelsen beskrives ved hjelp av et utførelseseksempel, og det henvises til vedføyde tegninger hvor: Fig. 1 viser i perspektiv ovenfra en sveiseanordning med en kanal for tilførsel av deler, en griper og et varmespeil i utgangsposisjon, Fig. 2 viser i perspektiv nedenfra sveiseanordningen med til-førselskanal for deler i aktiv posisjon, Fig. 3 viser i perspektiv nedenfra sveiseanordningen med varmespeilet i aktiv posisjon. The invention is described with the help of an embodiment example, and reference is made to the attached drawings where: Fig. 1 shows in perspective from above a welding device with a channel for the supply of parts, a gripper and a heat mirror in the starting position, Fig. 2 shows in perspective from below the welding device with supply channel for parts in active position, Fig. 3 shows in perspective from below the welding device with the heat mirror in active position.

I fig. 1 angir henvisningstallet 1 en stempelsylinder med en vristiv stempelstang 2 som er festet til et hode 3. En griper 4 av kjent type er innrettet til å gripe og holde plastdeler mellom fingre 5. Griperen 4 er anordnet linjært bevegbar i stempelstangens 2 lengderetning idet griperen 4 er montert på en blokk 6 som kan gli på føringer 7 og forskyves ved hjelp av en stempelsylinder 8. Et varmespeil 9 er dreibart lagret mellom to parallelle armer 10. Armene 10 er videre dreibart lagret i hodet 3, og en vr imot or 12 er innrettet til å bevege armene 10 med varmespeilet 9 mellom to ytterposisjoner slik som vist i henholdsvis fig. 2 og fig. 3. En bevegelig kanal 13 er festet til armer 14 som er dreibart festet til en brakett 15 som er justerbart festet til stempelsylinderen 1. En stempel- sylinder 16 er anordnet mellom armene 14 og brakett en 15 og innrettet til å bevege kanalen 13 slik at kanalens 13 utløps- ende kan bringes inn foran griperens 4 fingre 5, slik som vist i fig. 2. Kanalen 13 står i forbindelse med en ikke vist mateanordning for plastdeler og er innrettet til å lede plastdeler fram til griperens 4 fingre 5. In fig. 1, the reference number 1 indicates a piston cylinder with a twistable piston rod 2 which is attached to a head 3. A gripper 4 of a known type is designed to grip and hold plastic parts between fingers 5. The gripper 4 is arranged to be linearly movable in the longitudinal direction of the piston rod 2 as the gripper 4 is mounted on a block 6 which can slide on guides 7 and is displaced with the help of a piston cylinder 8. A heat mirror 9 is rotatably stored between two parallel arms 10. The arms 10 are further rotatably stored in the head 3, and a vr opposite or 12 is arranged to move the arms 10 with the heating mirror 9 between two outer positions as shown in fig. 2 and fig. 3. A movable channel 13 is attached to arms 14 which are rotatably attached to a bracket 15 which is adjustably attached to the piston cylinder 1. A piston cylinder 16 is arranged between the arms 14 and bracket 15 and arranged to move the channel 13 so that the outlet end of the channel 13 can be brought in front of the fingers 5 of the gripper 4, as shown in fig. 2. The channel 13 is connected to a feeding device for plastic parts, not shown, and is designed to guide plastic parts to the fingers 5 of the gripper 4.

Når en ikke vist plastdel skal sveises fast til en plastkon-struks jon, bringes kanalen 13 i aktiv stilling slik som vist i fig. 2, ved hjelp av stempelsylinderen 16, og plastdelen ledes via kanalen 13 inn mellom griperens 4 fingre 5, hvoretter griperen 4 beveges mot kanalens 13 utløp ved hjelp av stempelsylinderen 8. Griperens 4 fingene 5 aktiveres og griper plastdelen, hvoretter griperen 4 returnerer og trekker plastdelen ut av kanalen 13 som så bringes tilbake til utgangsposisjon ved hjelp av stempelsylinderen 16. When a plastic part, not shown, is to be welded to a plastic construction, the channel 13 is brought into the active position as shown in fig. 2, by means of the piston cylinder 16, and the plastic part is guided via the channel 13 into between the fingers 5 of the gripper 4, after which the gripper 4 is moved towards the outlet of the channel 13 by means of the piston cylinder 8. The fingers 5 of the gripper 4 are activated and grip the plastic part, after which the gripper 4 returns and pulls the plastic part out of the channel 13 which is then brought back to the starting position by means of the piston cylinder 16.

Vrimotoren 12 dreier armene 10, slik at varmespeilet 9 an-bringes foran fingrene 5, se fig. 3. Stempelsylinderen 8 aktiveres og griperen 4 forskyves slik at den ikke viste plastdel presses mot varmespeilets 9 bakside. Stempelsylinderen 1 aktiveres og fører varmespeilets forside mot en ikke vist plastkonstruksjon, hvoretter stempelsylinderen 1 på kjent måte gjøres kraftløs. Ved å legge inn en passende ventetid fra plastdelen presses mot varmespeilets 9 bakside til varmespeilets forside kommer i kontakt med plastkonstruksjonen, kan plastdel og plastkonstruksjon tilføres riktig varmemengde i forhold til godstykkelse. Om plastkonstruksjonen trenger mer varme enn plastdelen, bringes varmespeilet 9 først inn til plastkonstruksjonen, hvoretter plastdelen etter en passende ventetid bringes i kontakt med varmespeilets 9 bakside. The turning motor 12 turns the arms 10, so that the heating mirror 9 is placed in front of the fingers 5, see fig. 3. The piston cylinder 8 is activated and the gripper 4 is displaced so that the plastic part, not shown, is pressed against the back of the heating mirror 9. The piston cylinder 1 is activated and leads the front of the heating mirror towards a plastic structure not shown, after which the piston cylinder 1 is rendered powerless in a known manner. By entering a suitable waiting time from the time the plastic part is pressed against the back of the heating mirror 9 until the front of the heating mirror comes into contact with the plastic construction, the plastic part and plastic construction can be supplied with the right amount of heat in relation to the material thickness. If the plastic construction needs more heat than the plastic part, the heating mirror 9 is first brought into the plastic construction, after which, after a suitable waiting time, the plastic part is brought into contact with the back of the heating mirror 9.

Når ønsket temperatur er nådd, trekkes hodet 3 med varmespeil 9 litt tilbake og ut fra plastkonstruksjonen. Vrimotoren 8 aktiveres og svinger armene 10 med varmespeilet 9 til side, og stempelsylinderen 1 føres fram slik at plastdelens oppvarmede flate kommer i kontakt med plastkonstruksjonens oppvarmede flate og sveises til denne. When the desired temperature is reached, the head 3 with heat mirror 9 is pulled slightly back and out from the plastic construction. The rotary motor 8 is activated and swings the arms 10 with the heating mirror 9 aside, and the piston cylinder 1 is advanced so that the heated surface of the plastic part comes into contact with the heated surface of the plastic construction and is welded to this.

Etter at sveising er gjennomført, åpnes griperens 4 fingre 5, og stempelsylinderen 1 aktiveres for å trekke hodet 3 tilbake til utgangsposisjon. After welding is completed, the fingers 5 of the gripper 4 are opened, and the piston cylinder 1 is activated to pull the head 3 back to its starting position.
