Description
Einrichtung zum Reinigen von Datenträgern Device for cleaning data carriers
Die Erfindung betrifft eine Einrichtung zum Reinigen von sich aufgrund von Reibung elektrostatisch leicht aufladenden Datenträgern, wie Filme, Schallplatten, Magnetbänder, bei welcher eine Relativbewegung zwischen Datenträger und mindestens einer Reinigungsbürste vorgesehen ist. The invention relates to a device for cleaning due to from friction, electrostatically slightly charging data carriers, such as films, records, Magnetic tapes in which a relative movement between the data carrier and at least a cleaning brush is provided.
Einrichtungen der eingangs genannten Art werden beispielsweise in fotografischen Kopiergeräten verwendet, um den als Vorlage dienenden Film vor seiner Eingabe in die Kopierstation von Staubpartikelchen und dergleichen zu befreien. Facilities of the type mentioned are for example in photographic copiers used to copy the original film in front of his To free input into the copying station of dust particles and the like.
Es hat sich dabei als-besonders nachteilig erwiesen, daß bei der Behandlung des Filmes mit Reinigungsbürsten dieser sich elektrostatisch auflädt. Um diese elektrostatische Aufladung zu vermeiden oder zu verringern, wurde in manchen Fällen die Luft um den Film ionisiert oder durchfeuchtet. Solche zusätzlichen Einrichtungen sind aber teuer und störend, da beispielsweise die Platzmöglichkeiten in einem Kopiergerät äußerst gering sind. Außerdem ist ein Ionisator mit unangenehmer Geruchsbelästigung verbunden. It has proven to be particularly disadvantageous that in the Treatment of the film with cleaning brushes, it becomes electrostatically charged. In order to avoid or reduce this electrostatic charge, some Cases the air around the film is ionized or moistened. Such additional Facilities but are expensive and annoying, for example because of the space available in a copier are extremely low. In addition, there is an ionizer with an unpleasant odor tied together.
Aufgabe der Erfindung ist es daher, eine Einrichtung der eingangs genannten Art derart weiterzubilden, daß zusätzliche, eine Aufladung verringernde oder verhindernde Vorrichtungen entfallen können.The object of the invention is therefore to provide a device of the above mentioned type in such a way that additional, a charge-reducing or preventive devices can be omitted.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 oder 2 beschriebene Erfindung gelöst.This task is achieved by the characterizing part of claim 1 or 2 invention described solved.
Mit der Erfindung wird erreicht, daß der Datenträger nach einer Aufladung direkt durch die Bürste entladen werden kann. Dadurch entfallen die oben genannten zusätzlichen Vorrichtungen.With the invention it is achieved that the data carrier after a charge can be discharged directly through the brush. This eliminates the above additional devices.
Als Fasermaterial können beispielsweise Carbonfasern verwendet werden. Diese Fasern sollten jedoch nur dann angewendet werden, wenn die mechanische Beanspruchung nicht zu groß ist, da sie verhältnismäßig leicht brechen.Carbon fibers, for example, can be used as the fiber material. However, these fibers should only be used when the mechanical stress is not too big as they break relatively easily.
Als besonders zweckmäßig, insbesondere für die Reinigung von Schallplatten, haben sich erfindungsgemäß Polyurethanschaumfolien mit eingelagerten Kohlenstoffteilchen oder Kupferteilchen erwiesen. Diese Folien werden dann in feinen Streifen verwendet.As particularly useful, especially for cleaning records, According to the invention, polyurethane foam films with embedded carbon particles have proven themselves or copper particles. These foils are then used in fine strips.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus den Unteransprüchen im Zusammenhang mit der Beschreibung von Ausführungsbeispielen, die anhand einer Figur erläutert werden. Die einzige Figur zeigt eine erfindungsgemäße Einrichtung zum Reinigen von Filmen.Further details and advantages of the invention emerge from the Subclaims in connection with the description of exemplary embodiments, which are explained with reference to a figure. The only figure shows one according to the invention Device for cleaning films.
In der Figur ist mit 1 eine Halterungsplatte bezeichnet, an welcher eine Abwickelspule 2 und eine Aufwickelspule 3 für ein Filmband 4 vorgesehen ist. Zwischen der Abwickelspule 2 und der Aufwickelspule 3 sind zwei Bürsten 5 und 6 derart angeordnet, daß der Film 4 nach jeweils der entgegengesetzten Richtung ausgelenkt wird. Damit greift die eine Bürste 5 auf der einen Seite des Filmes an, wogegen die andere Bürste 6 den Film auf der anderen Seite reinigt.In the figure, 1 designates a mounting plate on which a supply reel 2 and a take-up reel 3 for a film tape 4 are provided. Between the supply reel 2 and the take-up reel 3 are two brushes 5 and 6 arranged in such a way that the film 4 is deflected in the opposite direction will. So that one brush 5 attacks on one side of the film, on the other hand the other brush 6 cleans the film on the other side.
Der Belag 7 der Bürsten besteht nun erfindungsgemäß aus leitfähigen Fasern. Statt der Fasern könnten ebenso auch leitfähige Folienstreifen verwendet werden. Als Alternativlösung der Erfindung können als Bürstenbelag bekannte Reinigungsborsten Anwendung finden, die für eine Staubentfernung besonders geeignet sind, zwischen welchen aber eine ausreichende Anzahl von leitfähigen Fasern oder Folienstreifen vorgesehen sind.According to the invention, the coating 7 of the brushes now consists of conductive ones Fibers. Instead of the fibers, conductive foil strips could also be used will. As an alternative solution to the invention, cleaning bristles known as a brush coating can be used Find application that are particularly suitable for dust removal between but which have a sufficient number of conductive fibers or strips of film are provided.
Als geeignete Materialien für die Fasern bzw. Folienstreifen können Carbonfasern, Kunststoff-Fasern mit Graphit versetzt, Polyurethanschaumfolien mit eingelagerten Kohlestoffteilchen oder Kupferteilchen und dergleichen vorgesehen werden.Can be used as suitable materials for the fibers or film strips Carbon fibers, plastic fibers mixed with graphite, polyurethane foam sheets with embedded carbon particles or copper particles and the like provided will.
Für die Reinigung von Schallplatten kann beispielsweise eine flache Bürste vorgesehen werden, welche in bekannter Weise an einem beweglichen Arm angebracht ist und auf der Schallplattenoberfläche aufliegt und von deren Rillen mitbewegt wird. Für die Reinigung von Schallplatten hat sich die Kombination von nichtleitfähigen Reinigungsborsten und leitfähigen Kunststoff-Folienstreifen als besonders geeignet erwiesen.For cleaning records, for example, a flat Brush can be provided, which is attached in a known manner to a movable arm is and rests on the record surface and is moved by its grooves will. For the cleaning of records, the combination of non-conductive Cleaning bristles and conductive plastic film strips are particularly suitable proven.
