Description

Permanentmagnetisk rullegang. Permanent magnetic rolling gear.

Oppfinnelsen angår en permanentmagnetisk rullegang som har minst to motsatt polariserte ruller med parallelle akser, som ligger overfor hverandre. De tjener til transport av stavformede materialer som rør, profiljern eller også andre gjenstander, der den magnetisk påvirkning i rullene ut-nyttes til å øke trykket av det materiale som transporteres mot rullene. Det er tid-ligere kjent å la et magnetsystem virke på rullene utenfra, slik at rullene får magnetiske klebeegenskaper som polariserte lege-mer. På den annen side har man også byg-get magnetsystemer inn i rullene. Slike ruller som på grunn av slitasje må skiftes ut krever da utskiftning resp. ny innbyg-ging av magnetsystemet i reserverullene. Av denne grunn foretrekkes derfor slike rulleganger, der rullene blir polarisert ved hjelp av magnetsystemer som ligger utenfor rullene, og som med fritt fremstikkende poler omslutter rullene over en del av deres omkrets, og i en avstand fra denne. Her må man fremfor alt ta hensyn til at spalten mellom overflaten av rullene og overflaten av magnetsystemet lett kan tilstoppes av partikler, som slites av og at de avslitte partikler for unngåelse av forstyrrelser praktisk talt bare kan utelukkes ved ut-bygning av rullene. The invention relates to a permanent magnetic roller conveyor which has at least two oppositely polarized rollers with parallel axes, which lie opposite each other. They serve to transport rod-shaped materials such as pipes, profiled iron or other objects, where the magnetic influence in the rollers is used to increase the pressure of the material being transported against the rollers. It is currently known to allow a magnetic system to act on the rolls from the outside, so that the rolls acquire magnetic adhesive properties like polarized bodies. On the other hand, magnet systems have also been built into the rollers. Such rollers which, due to wear and tear, must be replaced then require replacement or new integration of the magnet system in the spare rollers. For this reason, such roller passages are therefore preferred, where the rollers are polarized by means of magnetic systems which lie outside the rollers, and which with freely projecting poles enclose the rollers over part of their circumference, and at a distance from this. Here, one must above all take into account that the gap between the surface of the rollers and the surface of the magnetic system can easily be blocked by particles, which are worn off and that the worn-out particles can practically only be excluded by expanding the rollers in order to avoid disturbances.

Hensikten med oppfinnelsen er å opp-heve denne ulempe ved utenfra polariserte rullegangsruller, og hensikten er oppnådd ved at magnetene er innsatt i rammen overfor rullenes endeflater mens de til-støtende rammedeler er utformet som magnetisk tilbakekopling. The purpose of the invention is to eliminate this disadvantage of externally polarized roller conveyors, and the purpose is achieved by the magnets being inserted in the frame opposite the end surfaces of the rollers, while the adjacent frame parts are designed as magnetic feedback.

Oppfinnelsen angår således en per- The invention thus relates to a per-

manentmagnetisk rullegang, særlig beregnet som drivinnretning for frem- og tilbakebevegelse av arbeidsbord, supporter og liknende, ved bearbeidelsesmaskiner, omfattende ruller som står med parallelle akser og er motsatt polarisert utenfra, og en ramme som bærer eller styrer minst to slike ruller anordnet etter hverandre, og den er i det vesentlige kjennetegnet ved at magnetene er innsatt i rammen overfor rullenes endeflater og at de tilhørende rammedeler er utformet som magnetisk tilbakekopling. manent magnetic roller conveyor, especially intended as a drive device for the back and forth movement of work tables, supports and the like, in processing machines, comprising rollers which stand with parallel axes and are oppositely polarized from the outside, and a frame which carries or controls at least two such rollers arranged one after the other, and it is essentially characterized by the fact that the magnets are inserted in the frame opposite the end surfaces of the rollers and that the associated frame parts are designed as magnetic feedback.

Det oppstår således et akseparallell-forløpende magnetfelt hvis luftspalte be-finner seg utenfor løpeflaten for rullene og mellom rammen og rullenes endeflater. Da det her ikke finnes noen slitasje påvir-kes ikke lenger rullenes rotasjon, og for de avslitte partikler som fremkommer på rullenes løpeflater finnes det muligheter til å falle av rullene, f. eks. ved at partiklene gnis av av det materiale som glir over rullene. An axis-parallel running magnetic field is thus created whose air gap is outside the running surface of the rollers and between the frame and the end surfaces of the rollers. As there is no wear here, the rotation of the rollers is no longer affected, and for the worn particles that appear on the running surfaces of the rollers there are opportunities to fall off the rollers, e.g. by the particles being rubbed off by the material that slides over the rollers.

Ytterligere trekk og fordeler ved oppfinnelsen vil fremgå av den følgende be-skrivelse av et utførelseseksempel under henvisning til tegningen, der: Fig. 1 viser et tverrsnitt gjennom rullegangen, og Further features and advantages of the invention will be apparent from the following description of an embodiment with reference to the drawing, where: Fig. 1 shows a cross-section through the roller passage, and

fig. 2 viser en del av rullegangen sett ovenfra. fig. 2 shows a part of the rolling passage seen from above.

Rullegangene består av rullene 1 med parallelle akser som er festet på aksler 2 av magnetisk ikke-ledende materiale ved hjelp av en kileforbindelse, og rullene er ved hjelp av akslene 2 lagt i lagre 5 i rammen som omfatter bløte jerndeler. Mot endeflatene av rullene 1 har hver av bløt-jerndelene 3, 4 rundt boringen for akselen 2 en konsentrisk utsparing 6 som strekker seg inn i rammens indre omtrent halvparten av dennes dybde, og er utført som en åpen hulkile, hvori det parallelt med rul-lens akse er innsatt permanentmagneter 7 som er fordelt radielt. Oppdelingen av polen er foretatt slik at rullene 1 innbyrdes, og hver bløtjerndel 3, 4 for seg, polariseres motsatt, slik at det mellom rullene 1 som ikke er innbyrdes magnetisk forbundet, dannes et magnetfelt og slik at det i bløt-jerndelene 3, 4 dannes en magnetisk til-bakekobling. The roller passages consist of the rollers 1 with parallel axes which are fixed on shafts 2 of magnetically non-conductive material by means of a wedge connection, and the rollers are by means of the shafts 2 placed in bearings 5 in the frame which comprise soft iron parts. Towards the end surfaces of the rollers 1, each of the soft iron parts 3, 4 around the bore for the shaft 2 has a concentric recess 6 which extends into the interior of the frame approximately half of its depth, and is designed as an open hollow wedge, in which parallel to the roller lens axis, permanent magnets 7 are inserted which are distributed radially. The division of the pole is made so that the rollers 1 interact with each other, and each soft iron part 3, 4 is polarized in the opposite direction, so that a magnetic field is formed between the rollers 1, which are not mutually magnetically connected, and so that in the soft iron parts 3, 4 a magnetic on-back connection is formed.

Foran utsparingene 6 i bløtjerndelene 3, 4 er det anordnet en plate 8 av magnetisk ikke-ledende materiale som er forsynt-med en boring for gjennomføring av akselen 2 og platen dekker forøvrig den side av det av permanentmagnetene 7 dannede magnetsystem som vender mot rullene 1. In front of the recesses 6 in the soft iron parts 3, 4, a plate 8 of magnetically non-conductive material is arranged which is provided with a bore for the passage of the shaft 2 and the plate otherwise covers the side of the magnetic system formed by the permanent magnets 7 which faces the rollers 1 .

Rullene 1 som består av bløtt magnetisk materiale har ved området ved endeflatene påsatte ringer 9, som består av magnetisk ikke-ledende materiale og som eventuelt er profilert. Ringene 9 har til formål å svekke de magnetiske hefteegen-skaper i nærheten av rullenes endeflater, slik at de materialer som ruller på rullene fortrinnsvis søker inn mot rullenes midt-parti fordi materialet her bedre kan transporteres fremover i transportbanen. The rollers 1, which consist of soft magnetic material, have attached rings 9, which consist of magnetically non-conductive material and which are optionally profiled, at the end surfaces. The purpose of the rings 9 is to weaken the magnetic adhesion properties near the end surfaces of the rollers, so that the materials rolling on the rollers preferably search towards the middle part of the rollers because the material here can be better transported forward in the transport path.

Da polariteten av rullene 1 til enhver tid fremkommer som summen av de like poler av de to magnetsystemer, oppstår det etm eget sterkt magnetfelt mellom rullene 1. Magnetfeltet tilveiebringer en særlig sik-ker transport av gjenstander som bare får punktformet berøring med rullene 1, som f. eks. rør. As the polarity of the rollers 1 at all times appears as the sum of the equal poles of the two magnetic systems, a separate strong magnetic field arises between the rollers 1. The magnetic field provides a particularly safe transport of objects that only come into contact with the rollers 1 in a point-like manner, which e.g. tube.
