Abstract

The fine particles produced in a record shredder, especially particles of film, do not settle at all readily in the collection container, because of their electrostatic charge. They spread around the surrounding area, especially when the collection container is removed from the shredder. A remedy is found according to the invention by making the inside walls of the collection container of an electrically conductive material, so that the particle charges are dissipated. The discharged particles settle in the selection container without problem.

Auffangbehälter für das in einem Schriftgutvernichter zerkleinerte MaterialCollecting container for that in a document shredder crushed material

Die Erfindung betrifft einen Auffangbehälter für das in einem Schriftgutvernichter zerkleinerte Material.The invention relates to a collecting container for the in one Shredder of shredded material.

In Sc-hriftgutvernichtern wird das zu vernichtende Schriftgut im Schneidwerk in Streifen oder Partikel zerkleinert. Insbesondere, sofern Mikrofilm zerkleinert wird und. sehr · kleine Filmpartikel erzeugt werden, ergeben sich Probleme, da die kleinen Partikel aufgrund ihrer elektrostatischen Aufladung die Tendenz haben,"im Auffangbehälter zu vagabundieren und sich dort nur z.T. abzusetzen. Gleiches gilt in' eingeschränkter Form für kleine Papierpartikel. Insbesondere beim Herausnehmen des Auffangbehälters aus dem Gerät ergeben sich erhebliche Probleme mit den herumfliegenden Partikeln.The written material to be destroyed is stored in document shredders cut into strips or particles in the cutting unit. Especially if microfilm is shredded and. very · Small film particles are generated, problems arise because the small particles are due to their electrostatic properties Charge have the tendency to "wander around in the collecting container and only partially drop off there. The same applies to a limited extent for small paper particles. In particular when removing the collecting container from the device there are considerable problems with the flying particles.

Um hier Abhilfe zu schaffen, ist es bereits bekannt, die Partikel .vom Schneidwerk abzusaugen. Diese Lösung ist jedoch relativ aufwendig und insbesondere für kleinere Geräte aus Kosten- und Platzgründen nicht geeignet.To remedy this, it is already known to use particles .sucked from the cutting unit. However, this solution is relative expensive and especially not suitable for smaller devices for reasons of cost and space.

Der Erfindung Liegt die Aufgabe zugrunde, mit einfachen Mit- ■ teln sicherzustellen, daß sich die Partikel.im Auffangbehälter absetzen.· ■The invention is based on the object with simple ■ ensure that the particles are in the collecting container discontinue. · ■

Diese Aufgabe wird erfindungsgemäß dadurch gelöst,.daß die Innenwandungen des Auffangbehälters aus einem elektrischAccording to the invention, this object is achieved in that the Inner walls of the collecting container from an electrically

leitfähigen Material beste.hen und daß diese Wandungen nsi-t der- Masse des Gerätes in Verbindung stehen.conductive material and that these walls are nsi-t the ground of the device.

Es ist erfindungsgemäß beispielsweise möglich, den Auffangbehälter mit einer leitfähigen metallischen Folie auszukleiden. An dieser Folie liegt, sobald der Auffangbehälter in« Gerät eingesetzt ist, zweckmäßigerweise eine Kontaktfeder an, die mit der Masse des Gerätes verbunden ist. Sobald die aus dem Schneidwerk des Sehr Lftgutvernichters austretenden elektrostatisch aufgeladenen Partikel mit der elektrischleitfähigen Folie in Berührung kommen, werden sie entluden und fallen unter Einfluß der Schwerkraft auf den Boden des Auffangbehälters. Die von den Partikeln· an die elektrisch leitfähige Folie abgegebene Ladung fließt über' die Kontaktfedern .an die Masse des Gerätes ab. Auf diese Weise wird mit einfachen Mitteln erreicht, daß sich die Partikel, auch die sehr kleinen Filmpartikel, einwandfrei im Auffangbehälter ablagern. Beim Herausnehmen des Auffangbehälters aus'dem Gerät bleiben die entladenen Partikel im Behälter liegen.-Eine Verschmutzung der Umgebung wird vermieden. . . "According to the invention, it is possible, for example, to use the collecting container to be lined with a conductive metallic foil. As soon as the collecting container is in « Device is used, expediently a contact spring which is connected to the mass of the device. As soon as the emerging from the cutting unit of the very air shredder electrostatically charged particles with the electrically conductive If they come into contact with the foil, they will be discharged and fall under the influence of gravity to the bottom of the Collecting container. The from the particles to the electrical The charge released through the conductive film flows through the contact springs to the mass of the device. That way will achieved with simple means that the particles, even the very small film particles, are perfectly in the collecting container deposit. When the collecting container is removed from the device, the discharged particles remain in the container Pollution of the environment is avoided. . . "

Erfindungsgemäß können die Wandungen des Auffangbehälter auch mit einer elektrisch leitfähigen Beschichtung versehen sein, die in an sich bekannter Weise aufgedampft oder galvanisch aufgebracht wird. Desgleichen ist es möglich, die Wandungen aus einem elektrisch leitfähigen Kunststoff, vorzugsweise aus einem kohlenstoffhaltigen Kunststoff, her,-zustellen. Sofern ein Auffangbeutel eingesetzt wird, ist es möglich, hier eine Folie mit elektrisch leitfähiger Oberfläche einzusetzen-. .·According to the invention, the walls of the collecting container also provided with an electrically conductive coating which is vapor-deposited or galvanically applied in a manner known per se. It is also possible the walls from an electrically conductive plastic, preferably from a carbon-containing plastic, to produce. If a collection bag is used, it is possible to use a film with an electrically conductive surface to use. . ·
