Kapazitiver Hochfrequenz-DurchlaufofenCapacitive high frequency continuous furnace

Die Erfindung bezieht sich auf einen kapazitiven Hochfrequenz-Durchlaufofen zum Trocknen von textlien Gewebe, insbesondere von Baumwollgewirken (Trikot), bei dem das Gewebe zwischen den Elektroden transportierbar ist.The invention relates to a capacitive high-frequency continuous furnace for drying textile fabrics, especially cotton knitted fabrics (tricot), where the Tissue can be transported between the electrodes.

Kapazitive Hochfrequenzöfen der vorgenannten Art sind in den verschiedensten AusfUhrungsformen bekannt (vgl. z.B. DE-OS 29 41 845, 28 17 067) und haben sich gut bei der Trocknung von Textilien bewährt.Capacitive high-frequency furnaces of the aforementioned type are known in a wide variety of designs (cf. e.g. DE-OS 29 41 845, 28 17 067) and have proven themselves well for drying textiles.

Im Rahmen des Fertigungsprozesses werden Textilgewebe nach verschiedenen Naßbehandlungen immer wieder getrocknet. Es ist dabei wünschenswert, daß vor allem bei den letzten Trocknungsvorgangen die Gewebe und hier vor allem die Gewirke bereits derart schrumpfen, daß der Endverbraucher beim Waschen und Trocknen des Gewebes nur noch eine kleine Restschrumpfung in Kauf nehmen muß.Textile fabrics are used as part of the manufacturing process repeatedly dried after various wet treatments. It is desirable that above all in the last drying processes the fabric and here Above all, the knitted fabrics are already shrinking in such a way that the end user is washing and drying the fabric only have to accept a small residual shrinkage.

Zum Trocknen im textlien Sektor werden häufig Kontakttrockner in Form von erhitzten Walzen benutzt. Diese Trocknung hat den Nachteil, daß der Schrumpfungsprozeß beim Trocknen durch eventuelles Festkleben der Gewebe auf den Rollen behindert wird. Ähnlich« Gesichtspunkte gelten auch hinsichtlich der bekannten Trocknung mit Luftdüsen oder der energieaufwendigen Trocknung in Siebtrommeln. Außerdem ist hier und bei Wäschetrocknern mit Wäscheschleudern immer eine gewisse Gefahr der Formveränderung gegeben.Contact dryers are often used for drying in the textile sector used in the form of heated rollers. This drying has the disadvantage that the shrinkage process is hindered during drying by possible sticking of the fabric on the rollers. Similar to «points of view also apply to the known drying with air nozzles or the energy-intensive drying in sieve drums. In addition, there is always a certain risk of shape change here and with tumble dryers with spin dryers given.

Als allgemeine Erfahrungstatsache kann gelten, daß sich mit diesen bekannten Trocknungsverfahren in etwa eine noch nachträglich eintretende Restschrumpfung von etwa 6 bis 7% erreichen läet.

As a general fact of experience, it can be said that with these known drying processes, a residual shrinkage of about 6 to 7% , which occurs afterwards, can be achieved.

Es wurde nun erkannt, daß die Anwendung von kapazitiver Hochfrequenzenergie - vor allem bei relativ labilen Geweben, wie z.B. Baumwollgewirken -, beträchtliche Verbesserungen in der Trocknungsgeschwindigkeit und Schrumpfbeständigkeit bringt.It has now been recognized that the use of capacitive High frequency energy - especially on relatively fragile fabrics such as knitted cotton - brings about significant improvements brings in drying speed and shrinkage resistance.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Hochfrequenz-Durchlaufofen der eingangs genannten Art so auszubilden, daß die Schrumpfungsbeständigkeit der mit Hochfrequenz behandelten Gewebe zusätzlich erhöhbar ist.The object of the present invention is to to design a high-frequency continuous furnace of the type mentioned in such a way that the shrinkage resistance the tissue treated with high frequency can also be increased.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß im Ofen eine mechanische Vorrichtung zum Schütteln des Gewebes während des TrocknungsVorganges angeordnet ist. Hierdurch läßt sich überraschenderweise eine deutlich unter 5% liegende Restschrumpfung des Gewebes erreichen. Dieser Effekt mag darauf beruhen, daß die bereits durch die Hochfrequenzerwärmung gelockerten Bindungskräfte zwischen den einzelnen Fäden des Gewebes an den Webkreuzungspunkten durch die zusätzliche mechanische Erschütterung noch weiter gelöst werden, so daß sich die Fäden beliebig gegeneinander verschieben und schrumpfen können. Ein derart frei geschrumpftes Gewebe ist dann späterhin relativ schrumpfbeständig.This object is achieved according to the invention in that a mechanical device for shaking the tissue during the drying process is arranged in the oven. In this way, surprisingly, a residual shrinkage of the fabric well below 5% can be achieved. This effect may be due to the fact that the binding forces between the individual threads of the fabric at the weaving crossing points, which have already been loosened by the high-frequency heating, are further loosened by the additional mechanical vibration, so that the threads can move and shrink against each other at will. A fabric that has been freely shrunk in this way is then later relatively resistant to shrinkage.

Als mechanische Schüttelvorrichtung kann z.B. eine periodisch auf das Transportband und/oder dessen Auflage einwirkende Schlagvorrichtung, z.B. in Form von Schlagnocken vorgesehen werden. Es ist aber auch möglich, das Transportband und/oder dessen Auflage pneu- As a mechanical shaking device, e.g. a periodically on the conveyor belt and / or its support Acting impact device, e.g. in the form of impact cams, can be provided. However, it is also possible to use the conveyor belt and / or its support with

- 1 - VPA 83 P 3 t 6 9 DE matisch in Schwingungen zu versetzen.- 1 - VPA 83 P 3 t 6 9 DE to vibrate automatically.

Alternativ ist es auch möglich, zum Transport des zu trocknenden Gutes einen Schüttelförderer zu verwenden 5 oder auch die Vibrationen durch Ultraschall zu erzeugen. In Jedem der vorgenannten Fälle ist es von Vorteil, wenn die SchUttelfrequenz und/oder Schüttelamplitude veränderbar sind, damit die RUttlung dem Jeweils vorliegenden Gewebe optimal angepaßt werden kann.Alternatively, it is also possible to transport the to to use a vibrating conveyor for drying goods 5 or to generate the vibrations by ultrasound. In each of the above cases it is advantageous if the shaking frequency and / or shaking amplitude can be changed, so that the vibration is present in each case Tissue can be optimally adapted.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels sei die Erfindung näher erläutert: Das zu trocknende Baumwollgewirke 7 in Form eines gefalteten Schlauches mit einer Schütthöhe zwischen 5 und cm läuft in Richtung des Pfeiles 6 auf einem Transportband 5 durch einen kapazitiven Hochfrequenzofen 1. Die Trocknung geschieht im wesentlichen durch das elektrische Feld, das sich zwischen der mit dem Hochfrequenzgenerator 2 verbundenen "heißen" Elektrode 3 und der geerdeten Gegenelektrode 10 ausbildet. Diese geerdete Gegenelektrode 10 ist im vorliegenden Fall ein Siebblech und bildet gleichzeitig die Auflage für das Transportband 5. Zusätzlich wird in den Hochfrequenzofen 1 noch Heißluft eingeblasen, die von einem Heißlufterzeuger 4 stammt. Diese gegebenenfalls im Umluftbetrieb gefahrene Heißluft dient zur zusätzlichen Trocknung und Abfuhr der verdampften Feuchte.The invention will be explained in more detail using an exemplary embodiment shown in the drawing: The knitted cotton fabric 7 to be dried in the form of a folded tube with a bed height between 5 and cm runs in the direction of arrow 6 on a conveyor belt 5 through a capacitive high-frequency furnace 1. The Drying takes place mainly through the electric field that is created between the high frequency generator 2 connected "hot" electrode 3 and the grounded counter electrode 10 forms. This grounded In the present case, the counter electrode 10 is a sieve plate and at the same time forms the support for the Conveyor belt 5. In addition, hot air is blown into the high-frequency furnace 1 from a hot air generator 4 originates. This hot air, which may be used in recirculation mode, is used for additional purposes Drying and removal of the evaporated moisture.

Zusätzlich ist im Hochfrequenzofen 1 noch eine mechanische Vorrichtung zum Schütteln des Baumwollgewirkeβ 7 während des Trocknungsvorganges angeordnet. Diese Schüttelvorrichtung kann beispielsweise aus von einem Motor angetriebenen Schlagnocken bestehen, wie durch das Bezugszeichen 8 angedeutet, die gegen die Auflage des Transportbandes 5 schlagen oder auch aus Düsen, durch die pulsierend Preßluft gegen die Auflage strömtIn addition, a mechanical device for shaking the cotton knitted fabric is in the high-frequency oven 1 7 arranged during the drying process. This shaking device can, for example, from a Motor-driven impact cams exist, as indicated by the reference numeral 8, against the support of the conveyor belt 5 or from nozzles through which compressed air flows in a pulsating manner against the support

und diese damit samt dem Gewirke zum Vibrieren bringt.and thus makes them vibrate together with the knitted fabric.

Die Rüttelfrequenzen und Rüttelamplituden sind dabei veränderbar.

The vibration frequencies and amplitudes can be changed.

Durch die Rüttlung werden die Bindekräfte zwischen den einzelnen Fäden der Gewebe zusätzlich gelockert, d.h. ein Effekt der Hochfrequenztrocknung noch unterstützt, so daß eine weitgehende unbehinderte Schrumpfung des Gewirkes während des Iransport- und Trocknungsvorganges möglich ist.Due to the vibration, the binding forces between the individual threads of the fabric are additionally loosened, i.e. an effect of the high-frequency drying is supported, so that a largely unhindered shrinkage of the knitted fabric during the transport and drying process is possible.
