Description
Bei der Entlausung von.-Kleidungsstücken, Betten,When delousing items of clothing, beds,
Zeltibahnen od. dgl., werden dlie Gegenstände z. B.Zeltibahnen od. The like., Dlie objects z. B.
in Säcke verpackt, auf einem Transportband durch das Hochfrequenzfeld, z. B. zwischen Kondeinsatorelektroden, faindurchgeschleust. Um zu verhindern, daß die Transportbänder auf Uhren Antriebswalzen rutschen, können' am dien Transportbändern Querstreifen, z. B.. durch Aufnähen, angebracht werden.packed in sacks, on a conveyor belt through the high frequency field, e.g. B. between capacitor electrodes, faind through. To prevent, that the conveyor belts slide on clocks drive rollers, there can be horizontal stripes on the conveyor belts, z. B .. by sewing, attached.
Darüber hinaus weiden die Mantelflächen! der Antriebswalizm geriffelt oder gerändelt.In addition, the outer surfaces graze! the drive valizm corrugated or knurled.
Betrielbsversuche haben nun ergeben, daß sich längs dieser Querstreifen sehr starke elektrische Felder ausbilden können, wenn das Transportband, wie es gelegentlich vorkommen kann, nicht senkrecht zu den Feldlinien steht. So wies z. B. ein Sack, in idem sich, zu entlausende Bekleidungsstücke 'befanden, mach- dler Hochtfrequenzbehanldlung auf •seiner Oberfläche streifenförmige Verbrennungen auf. Aus idem Abstand und der Richtung der Ansengstreifen war zu erkennen, daß die Querstreifen der Transportbänder Anlaß zu dieser Verbrennungserscheinung gaiben. Experiments in operation have now shown that there are very strong electrical lines along these transverse stripes Fields can form if the conveyor belt, as can occasionally happen, is not vertical to the field lines. So pointed z. B. a sack, in idem itself, items of clothing to be deloused 'found machedler high frequency treatment on • streaked burns on its surface on. From the same distance and the direction of the scorch strips it could be seen that the horizontal stripes of the conveyor belts gave rise to this burning phenomenon.
Durch die Erfindung wird der Nachteil der bekannten Transporteinrichtung vermieden. Erfindungsgemiäß weriden die an' dem Förderband angeordneten Quernippen mindestens an einer, vorzugsweise an mehreren Stellen unterbrochen.The invention avoids the disadvantage of the known transport device. According to the invention are the transverse ribs arranged on the conveyor belt on at least one, preferably interrupted in several places.
Durch die Unterteiiunig der Querrippen ergibt sich der wesentliche Vorteil, daß nunmehr Überschlage und übermäßige Erwärmungen der Querrippen im Hochfrequenzfeld) nicht mehr auftreten können.Due to the subdivision of the transverse ribs the main advantage that now rollover and excessive heating of the transverse ribs in the high-frequency field) no longer occur can.
Die Querrippen des Förderbandes erwärmen sich im Hochfrequenzfelid! besonders stark, da das Baumaterial der Unterlagen eine ungenügende Härte aufweist und durch das Reiben feiner Metallstaub von den Unterlagen abgeschliffen wird. Infolgedessen werden diese 'Querrippen1 im Laufe des Betriebes mehr oder weniger leitend. Außerdem entstehen aber bei Belastung des Förderbandes, bei der also das Förderband nicht mehr eben im Hodhfrequenzfeld liegt, sondern, mehr oder weniger duirchgabeuit wird, Feldverizerrungen, wobei die Feldlinien in den leitenden: Querrippen konzentriert werden und bei Durchbeulung auoh in konzentrierter Form austreten. Bei .'Unterteilung der Querrippen ist eine Konzentrierung der Feldlinien nicht in großem Maße möglich, so daß auch die austretenden Feldlinien keine Verbrennungen mehr hervorrufen.The cross ribs of the conveyor belt heat up in the high frequency field! particularly strong, as the construction material of the underlay is insufficiently hard and fine metal dust is abraded from the underlay by rubbing it. As a result, these 'transverse ribs 1 become more or less conductive in the course of operation. In addition, when the conveyor belt is loaded, i.e. when the conveyor belt is no longer in the high frequency field, but more or less duirchgabeuit, field distortions occur, whereby the field lines are concentrated in the conductive transverse ribs and also emerge in a concentrated form when they bulge. When the transverse ribs are subdivided, it is not possible to concentrate the field lines to a large extent, so that the emerging field lines no longer cause burns either.
In der Zeichnung ist ein Transportband gemäß der Erfindung dargestellt.In the drawing, a conveyor belt is according to of the invention shown.
Fig. ι zeigt das Transportband 1 im Grundriß; die Querrippen 21 weisen mehrere Unterbrechungen 3 auf, so daß eine übermäßige Erhitzung während des Betriebes nicht mehr erfolgen kann;Fig. Ι shows the conveyor belt 1 in plan; the transverse ribs 2 1 have several interruptions 3, so that excessive heating can no longer occur during operation;
Fig. 2 zeigt das Förderband 1 von der Seite; bei dieser Figur sind die Querrippen 21 als· kleine Erhebungen erkennbar, während die Lücken 3 bei dieser Figur nicht sichtbar sind.Fig. 2 shows the conveyor belt 1 from the side; In this figure, the transverse ribs 2 1 can be seen as small elevations, while the gaps 3 are not visible in this figure.
Die Erfindung ist nicht nur bei Entlausungseinrichtungen anwendbar, sondern kann, darüber hinaus überall da angewandt werden, wo· Gut irgendwelcher Art mittels Transportbänder durch das. Hochfrequenzfelid geführt wird undi wo das Transportband durch das aufliegende Gut nicht gleichmäßig über die Breite beansprucht1 wird.The invention is applicable not only to delousing, but can be moreover applied wherever · Good any kind is passed through the. Hochfrequenzfelid by means of conveyor belts undi where the conveyor belt through the overlying Good not claimed uniformly over the width 1 is.
