Description
Durchlauftrockner für Fotokopien Die Erfindung betrifft einen Durchlauftrockner für Fotokopien mit einem endlosen Transportband zum Vorbeiführen des Trockengutes an einem oder mehreren Strahlkörpern, z. B. Infrarotstrahlern.Continuous dryer for photocopies The invention relates to a continuous dryer for photocopies with an endless conveyor belt to guide the dry goods past on one or more radiators, e.g. B. Infrared emitters.
Da bei solchen Trocknern das Trockengut vom Transportband abrutscht, sobald es um einen bestimmten Teil seiner Länge überhängt, hielt man es bisher für erforderlich, das- Transportband den Strahlungsbereich, innerhalb dessen die Trocknung stattfindet, um mindestens die halbe Länge der größten vorkommenden. Trockengutformate überragen zu lassen, um zu vermeiden, daß sich die Kopien noch innerhalb des Strahlungsbereiches vom Band abheben., Erfindungsgemäß wird dieser Nachteil ohne Vergrößerung der Baulänge des Trockners dadurch vermieden, daß im Anschluß an das Transportband -welches in diesem Fall den Strahlungsbereich nicht zu überragen braucht - ein mit der Bandgeschwindigkeit umlaufendes Rollenpaar angeordnet wird, welches die zu trocknenden Fotokopien nach dem Verlassen des Bandes erfaßt.Since the drying material slips off the conveyor belt in such dryers, as soon as it overhangs a certain part of its length, it was previously thought to be required, the conveyor belt the radiation area within which the drying takes place to at least half the length of the largest occurring. Dry goods formats to protrude in order to avoid that the copies are still within the radiation area lift off the tape. According to the invention, this disadvantage is achieved without increasing the overall length of the dryer avoided that following the conveyor belt -which in In this case, the radiation area does not need to protrude - one with the belt speed rotating pair of rollers is arranged, which the photocopies to be dried after detected when leaving the belt.
Die Erfindung ist in der Beschreibung eines in der Zeichnung dargestellten Ausführungsbeispieles erläutert.The invention is illustrated in the description of a in the drawing Embodiment explained.
Das in der Zeichnung halbschematisch wiedergegebene Gerät enthält eine Reihe von Infrarotstrahlern 1. Im Bereich der- Strahlung derselben ist ein endloses Band 2 angeordnet, das die Form eines aus dünnen Drähten gebildeten Kettenbandes aufweist, welches über Kettenräder 3 läuft. Die Breite dieses Kettenbandes entspricht ungefähr derjenigen der zu trocknenden Fotokopien. Die Kettenräder 3 sind durch einen vorzugsweise stufenlos regelbaren Elektromotor 4 .angetrieben. Anschließend an das Ketten, band ist ein Paar mit Gummi oder ähnlichen Stoffen b:legter Rallen 5 und 6 vorgesehen, deren Berührungsebene sich auf gleicher Höhe befindet wie die Ebene des oberen Trums des Kettenbandes 2. Der Antrieb der Rolle 5 ist von demjenigen der Ketten, räder 3 derart abgeleitet, daß ihre Umfangsgeschwindigkeit der Umlaufgeschwindigkeit :des Kettenbandes entspricht. Die Rolle 6 ist an einer Schwinge 7 aufgehängt und legt sich durch ihr Gewicht gegen die Rolle 5 an. Die Breite der Rollen kann wesentlich kleiner sein als diejenige des Bandes 2.The device shown semi-schematically in the drawing contains a number of infrared emitters 1. In the area of the radiation the same is a endless belt 2 arranged, which is in the form of a chain belt formed from thin wires which runs over sprockets 3. The width of this chain belt corresponds to approximately that of the photocopies to be dried. The sprockets 3 are through a preferably continuously variable electric motor 4 .driven. Afterward the chain is tied with a pair of ratchets covered with rubber or similar material 5 and 6 provided, the contact plane is at the same level as that Level of the upper run of the chain belt 2. The drive of the roller 5 is from that one of the chains, wheels 3 derived in such a way that their peripheral speed corresponds to the rotational speed : corresponds to the chain belt. The roller 6 is suspended from a rocker 7 and rests against the roller 5 due to its weight. The width of the rolls can be substantial be smaller than that of band 2.
