Description
Den foreliggende oppfinnelse angår en fremgangsmåte for å utmate pulverkorn som i en elektrostatisk ladean-oraning er bLitt ladet ved friksjonsladning i bøyde, lanae kanaler fremstilt av elektrisk ikke-ledende materiale. The present invention relates to a method for discharging powder grains which, in an electrostatic charging arrangement, have been charged by frictional charging in bent, curved channels made of electrically non-conductive material.
Hovedformålet med den foreliggende oppfinnelse er i første rekke å tilveiebringe en fremgangsmåte av den ovenfor angitte type som muliggjør effektiv transport og til-førsel av ladede pulverkorn i stor avstand fra utmatnings-enheten for å nå frem til dyptliggende hjørner og andre dype partier på for eksempel skap, bjelker etc. som man ønsker å belegge med ladet pulver, fortrinnsvis farvepulver, samtidig som man ønsker å oppnå en jevn skikt-tykkelse. The main purpose of the present invention is primarily to provide a method of the above-mentioned type which enables efficient transport and supply of charged powder grains at a great distance from the discharge unit in order to reach deep-lying corners and other deep parts of, for example cupboards, beams etc. which you want to coat with charged powder, preferably colored powder, while you want to achieve an even layer thickness.
De nevnte formål oppnås ved hjelp av en fremgangsmåte ifølge den foreliggende oppfinnelse. The aforementioned purposes are achieved by means of a method according to the present invention.
Et ytterligere formål ved oppfinnelsen er å tilveiebringe en anordning som kan anvendes ved utførelsen av fremgangsmåten ifølge oppfinnelsen. A further object of the invention is to provide a device which can be used in carrying out the method according to the invention.
Det nevnte ytterligere formål oppnås ved hjelp av en anordning ifølge foreliggende o<p>pfinnelse. The aforementioned further purpose is achieved by means of a device according to the present invention.
O<p>pfinnelsen er nedenfor beskrevet i form av et fore-trukket utførelseseksempel, idet det vises til de vedføyede tegninger på hvilke The invention is described below in the form of a preferred embodiment, reference being made to the attached drawings in which
Fig. 1 viser en utmatningsanordning utført ifølge oppfinnelsen og sett skrått forfra, Fig. 2 viser spredningsbildet for ladet pulver når anordningen ikke er i bruk, Fig. 3 viser spredningsbildet for pulver når anordningen er i bruk, Fig. 4 viser et eksempel på et sprøytemunnstykke for hvilket oppfinnelsen kan tillem<p>es, og Fig. 5 viser anvendelsen av et slikt sprøytemunnstykke ved overflatebelegning av en dyp bjelke med pulver. Fig. 1 shows a dispensing device made according to the invention and seen obliquely from the front, Fig. 2 shows the spread pattern for charged powder when the device is not in use, Fig. 3 shows the spread pattern for powder when the device is in use, Fig. 4 shows an example of a spray nozzle for which the invention can be adapted, and Fig. 5 shows the use of such a spray nozzle when surface coating a deep beam with powder.
Pulver, fortrinnsvis farvepulver, som lades på kjent måte i en elektrostatisk ladeanordning 1 som innbefatter en rekke buede kanaler av elektrisk ikke-ledende materiale, tilføres i det viste eksempel en munnstykkeanordning 2 ifølge oppfinnelsen som er forbundet med ladeanordningen 1 og som fortrinnsvis omfatter en rekke utmatningsrør 3 som er vridbare rundt en leder 4. De nevnte rør kan reguleres til ønsket stilling og gjøres istand til å nå frem til såvel innsiden 5A som utsiden 5B av en gjenstand 5, en bjelke, kasse, skap etc, som det er ønsket å belegge med ladet pulver. Ved ytterenden 3A av de respektive rør 3 er en fortrinnsvis hylseformig munnstykkedel 6 anordnet som fortrinnsvis er tredd på røret 3 slik at den kan forskyves langs dette over en viss strekning. I avstand fra pulverutmatningsmunningen 7 for de nevnte rør 3 og midtparti av munnstykkedelen 6 er en rekke lufttilførselsorganer 8 anordnet ved de respektive munnstykkedeler 6. Fortrinnsvis dannes det nevnte organ 8 av lanselignende rør som med den ene ende 8A er festet i en gjennomstrømningskanal 9 ved munnstykkedelen 6, slik at de strekker seg i retning fra munnstykkedelen 6 og hovedsakelig i utmatningsretningen for pulver. Lufttilførselsmunningene 10 for de nevnte organ 8 befinner seg gunstig i avstand fra pulverutmatningsmunningen 7 for de respektive munnstykkedeler 6. Til-førselsslanger 11 for trykkluft, fortrinnsvis luft som oppviser høyt trykk, for eksempel med et trykk av mellom 2-4 bar, kan med den ene respektive ende 11A være forbundet med trykkilden, for eksempel en kompressor, via en luft-tilførselsledning 13 som via en forgreningskopling 12 er forbundet med en rekke slanger 11, og med en motstående ende 11B være forbundet med en passende luftgjennom-strømningskanal 9. Powder, preferably color powder, which is charged in a known manner in an electrostatic charging device 1 which includes a number of curved channels of electrically non-conductive material, is supplied in the example shown to a nozzle device 2 according to the invention which is connected to the charging device 1 and which preferably comprises a number of output pipes 3 which are rotatable around a conductor 4. The said pipes can be adjusted to the desired position and made ready to reach both the inside 5A and the outside 5B of an object 5, a beam, box, cupboard etc., which it is desired to coat with charged powder. At the outer end 3A of the respective tubes 3, a preferably sleeve-shaped nozzle part 6 is arranged which is preferably threaded onto the tube 3 so that it can be displaced along it over a certain distance. At a distance from the powder discharge mouth 7 for the aforementioned tubes 3 and the middle part of the nozzle part 6, a number of air supply devices 8 are arranged at the respective nozzle parts 6. Preferably, the mentioned device 8 is formed by lance-like tubes which with one end 8A are fixed in a flow channel 9 at the nozzle part 6, so that they extend in the direction from the nozzle part 6 and mainly in the discharge direction for powder. The air supply mouths 10 for the aforementioned organs 8 are conveniently located at a distance from the powder discharge mouth 7 for the respective nozzle parts 6. Supply hoses 11 for compressed air, preferably air that exhibits high pressure, for example with a pressure of between 2-4 bar, can one respective end 11A be connected to the pressure source, for example a compressor, via an air supply line 13 which is connected via a branch connection 12 to a number of hoses 11, and with an opposite end 11B be connected to a suitable air flow channel 9.
I det viste eksempel er to lufttilførselsorganer 8 beliggende i hovedsakelig samme avstand fra pulverutmatningsmunningen 7 og strekker seg hovedsakelig parallelt med hverandre. Det er mulig å tilkoble det ønskede antall tilførselsorganer 8 med det ønskede mønster langs omkretsen av munnstykkedelen 6, for eksempel ved at de er lagret bevegelig, for eksempel vridbare, i forhold til munnings-delen 6. In the example shown, two air supply means 8 are located at substantially the same distance from the powder discharge mouth 7 and extend substantially parallel to each other. It is possible to connect the desired number of supply means 8 with the desired pattern along the circumference of the mouthpiece part 6, for example by having them stored movable, for example rotatable, in relation to the mouth part 6.
Den nevnte anordning funksjonerer som følger, idetThe aforementioned device functions as follows, in that
det i første rekke vises til Fig. 2 og 3. På Fig. 2 er det vist hvorledes spredningsbildet 14 blir ved en munnstykkedel 6 ved utsprøyting av ladet pulver som trans- first of all, reference is made to Figs. 2 and 3. Fig. 2 shows how the scattering image 14 is formed by a nozzle part 6 when spraying charged powder that trans-
porteres ved hjelp av luft, ved en vanlig munnstykkedel, dvs. at pulveret spres med stor spredningsvinkel. På ported with the help of air, with a normal nozzle part, i.e. that the powder is spread with a large spreading angle. On
Fig. 3 er det vist hvorledes spredningsbildet 15 for pulver kan bli ved å tillempe den foreliggende oppfinnelse, dvs. at pulveret 16 efter utmatningen fra pulverutmatningsmunningen 7 i kjegleform påvirkes av trvkkluften 17 som tilføres via lufttilførselsorganene 8 og strømmer ut via lufttilførsels-munningene 10 og som danner en bærestråle som har høyere trykk enn den utmatede pulverstråle, og ved lignende ejektorvirkning medejekteres i en styrebærestråle 18 med høyere impuls og med mindre bredde, dvs. at det fås en hastighetsøkning av pulverpartiklene samt en styring av pulverskyens 16 utseende. Ladningen av pulveret 16 blir hovedsakelig bibeholdt under hele utmatningsstadiumet fra munnstykket 2, og det blir for den konsentrerte luft-pulverstråle 18 gjort mulig effektivt å tilføre det ladede pulver på ønsket sted, selv i lang avstand fra pulverutmatningsmunningen 7, for eksempel ved dype skap, kasser eller som ved bjelken 5, som vist på Fig. 5. Fig. 3 shows how the dispersion pattern 15 for powder can be by applying the present invention, i.e. that the powder 16 after being discharged from the powder discharge mouth 7 in the form of a cone is affected by the pressure gap 17 which is supplied via the air supply means 8 and flows out via the air supply mouths 10 and which forms a carrier jet that has a higher pressure than the ejected powder jet, and by similar ejector action is co-ejected in a control carrier jet 18 with a higher impulse and with a smaller width, i.e. an increase in the speed of the powder particles as well as a control of the appearance of the powder cloud 16 is obtained. The charge of the powder 16 is mainly maintained throughout the discharge stage from the nozzle 2, and it is made possible for the concentrated air-powder jet 18 to effectively supply the charged powder at the desired location, even at a long distance from the powder discharge mouth 7, for example in deep cabinets, boxes or as with beam 5, as shown in Fig. 5.
Et egnet materiale for anordningen kan være et plast-materiale . A suitable material for the device can be a plastic material.
Oppfinnelsen er ikke begrenset til det eksempel somThe invention is not limited to the example which
er beskrevet ovenfor og vist på tegningene, men kan varieres innen rammen av efterfølgende paptentkrav uten å avvike fra oppfinnelsesidéen. Eksempelvis ville en ringformig luft-utmatningsspalte som kunne strekke seg rundt en pulverut-matningsmunning i ønsket avstand, sett i sideretning henholdsvis i pulverutmatningsretningen, kunne fungere som lufttilførselsmunning. Som luft- turde også andre pneumat-iske gassformige fluida kunne innbefattes enn luft, og for eksempel skulle ionisert luft kunne komme på tale. is described above and shown in the drawings, but can be varied within the framework of subsequent patent claims without deviating from the idea of the invention. For example, an annular air discharge slot which could extend around a powder discharge opening at the desired distance, seen laterally or in the powder discharge direction, could function as an air supply opening. Like air, other pneumatic gaseous fluids could also be included than air, and for example ionized air could come into play.
