Abstract

Le dispositif permettant de verser du toner dans un appareil à copier comprend un raccord de remplissage (6) pouvant être fixé sur l'appareil pour y demeurer. L'extrémité supérieure de ce raccord est munie d'une trémie (7) recevant un récipient de toner interchangeable (1). Le récipient est constitué d'un récipient en matière synthétique rempli de toner, dont une extrémité forme un goulot (1') et est fermée hermétiquement par une feuille (2). La feuille (2) est, par exemple une feuille d'aluminium revêtue de matière synthétique et pouvant être scellée à chaud. Lorsque le récipient (1) est introduit dans la trémie (7), un organe d'ouverture (5) fixé à la trémie détache la feuille de façon qu'environ un dixième de sa périphérie reste attaché au bord et que la feuille soit pressée vers l'extérieur par l'écoulement du toner libéré. Le récipient vide peut rester dans le raccord comme protection contre l'entrée de corps étrangers jusqu'à ce qu'il soit remplacé par un nouveau récipient. En variante, le récipient vide est enlevé et le raccord est fermé par un couvercle (4).The device for pouring toner into a copying device includes a refill connector (6) which can be attached to the device to remain there. The upper end of this connector is provided with a hopper (7) receiving an interchangeable toner container (1). The container consists of a plastic container filled with toner, one end of which forms a neck (1') and is hermetically closed by a foil (2). The sheet (2) is, for example, an aluminum sheet coated with synthetic material and capable of being heat sealed. When the container (1) is introduced into the hopper (7), an opening member (5) attached to the hopper detaches the sheet so that approximately one tenth of its periphery remains attached to the edge and the sheet is pressed outwards by the flow of released toner. The empty container can remain in the fitting as protection against the entry of foreign bodies until it is replaced by a new container. Alternatively, the empty container is removed and the connection is closed with a cover (4).

Description

Vorrichtung zum Einfüllen von Toner Device for filling in toner
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Einfüllen von Toner in ein Kopier¬ gerät, insbesondere ein Laser-Kopiergerät.The present invention relates to a device for filling toner into a copier, in particular a laser copier.
Der Toner für solche Geräte besteht aus einem Kohlenstoffpulver feinster Korngrösse, das sehr schwierig zu handhaben ist, weil es sehr stark schmutzt und einge¬ tretene Verschmutzungen kaum mehr zu entfernen sind. Das Ein- und Nachfüllen von Toner ist daher insbeson¬ dere bei grossen Geräten eine heikle, unangenehme und zeitraubende Arbeit. Auch vermochten die bisherigen Packungen keine wesentliche Verbesserung und Verein¬ fachung zu erbringen.The toner for such devices consists of a carbon powder of the finest grain size, which is very difficult to handle because it is very dirty and dirt that can hardly be removed. Filling and refilling toner is therefore a delicate, uncomfortable and time-consuming task, particularly in the case of large devices. The previous packs were also unable to bring about any significant improvement and simplification.
Die vorliegende Erfindung ermöglicht es nun, die Schwierigkeiten beim Einfüllen des Toners, insbe¬ sondere bei grossen Geräten, mit Hilfe einer einfachen Packung und dem dazu gehörenden Einfüllstutzen zu be¬ heben. Die erfindungsge ässe Vorrichtung zum Ein¬ füllen von Toner besteht aus einem auf das Kopiergerät zu montierenden Einfüllstutzen und einer auf diesen Ein¬ füllstutzen aufsetzbaren, auswechselbaren, mit Toner gefüllten Tonerpackung. Die Vorrichtung ist in Patent¬ anspruch 1 definiert.The present invention now makes it possible to overcome the difficulties in filling the toner, in particular in the case of large devices, with the aid of a simple pack and the associated filler neck. The device according to the invention for filling in toner consists of a filler neck to be mounted on the copying machine and a replaceable toner pack filled with toner that can be placed on this filler neck. The device is defined in claim 1.
Die Erfindung bezieht sich ferner auf ein Ver¬ fahren zum Betrieb der neuen Vorrichtung, das in Patent¬ anspruch 5 definiert ist.The invention further relates to a method for operating the new device, which is defined in claim 5.
««
Die neue Vorrichtung wird an dem in der beilie¬ genden Zeichnung gezeigten Beispiel näher erläutert, welche einen Schnitt durch eine Ausführungsform einer Tonervorrichtung mit einer in den Einfüllstutzen einge¬ setzten Tonerpackung zeigt.The new device is explained in more detail using the example shown in the accompanying drawing, which shows a section through an embodiment of a toner device with a toner pack inserted into the filler neck.
Der Einfüllstutzen 6, der mit Vorteil aus einer Aluminiumlegierung besteht, ist mit Hilfe des Befestigungs¬ elementes 10 auf dem Kopiergerät montiert. Dieser Stutzen kann derart ausgebildet sein, dass er teleskopisch aus¬ ziehbar und in ausgezogenem Zustand durch eine Rastvor¬ richtung (nicht dargestellt) fixierbar ist, um vor unbe¬ absichtigtem Einschieben gesichert zu werden. Durch, die Ausziehbarkeit des Stutzens ist gewährleistet, dass eine allfällig darunter liegende, vorhandene Splice-Vor- richtung des Kopiergerätes ohne BehinderungThe filler neck 6, which advantageously consists of an aluminum alloy, is mounted on the copier with the aid of the fastening element 10. This nozzle can be designed such that it can be telescopically pulled out and, in the pulled-out state, can be fixed by a locking device (not shown) in order to be secured against inadvertent insertion. The fact that the socket can be pulled out ensures that any existing splice device of the copying machine underneath is unobstructed
OMPI durch die Einfüllvorrichtung bedient werden kann.OMPI can be operated by the filling device.
Der Einfüllstutzen weist einen Halsteil auf, der an seinem oberen Ende mit einem Einlauftrichter 7, einem Dichtungselement 4, z.B. einem Abstreifring, und einem Element 5 zum Oeffnen der Tonerpackung versehen ist.The filler neck has a neck part which is connected at its upper end to an inlet funnel 7, a sealing element 4, e.g. a scraper ring, and an element 5 for opening the toner pack is provided.
Die Tonerpackung 1 ist im dargestellten Aus¬ führungsbeispiel ein flaschenförmiger Kunststoffbehälter, der z.B. prismatisch oder zylindrisch ist, zur besseren Platzausnutzung im allgemeinen die Form eines Quaders aufweist, jedoch auch eine andere Form haben kann. Um ein rasches und reibungsloses Umfüllen des Toners zu gewährleisten, ist es wichtig, dass sich der BehälterIn the exemplary embodiment shown, the toner pack 1 is a bottle-shaped plastic container which e.g. is prismatic or cylindrical, generally has the shape of a cuboid for better use of space, but can also have a different shape. To ensure that the toner is refilled quickly and smoothly, it is important that the container
_ an einem Ende zu einem Auslasshals 1' verjüngt. Dieser Hals 1 f endet vorzugsweise in einem Rand von rundem Querschnitt. Der Hals ist luftdicht verschlossen, z.B. mit Hilfe einer auf den Rand aufgeschweissten, mit Kunst-. Stoff beschichteten Aluminiumfolie 2._ Tapered at one end to an outlet neck 1 '. This neck 1 f preferably ends in an edge of round cross section. The neck is sealed airtight, for example with the help of a plastic welded onto the edge. Fabric coated aluminum foil 2.
Der Kunststoffbehälter besteht z.B. aus PVC, Polystyrol, Polyamid, Polyäthylen oder jedem anderen Kunststoff von genügender Festigkeit, der sich auf übli¬ chen Maschinen verfor en lässt.The plastic container is e.g. made of PVC, polystyrene, polyamide, polyethylene or any other plastic of sufficient strength that can be deformed on conventional machines.
Das Element 5 zum Oeffnen der aufgesetzten Toner¬ packung ist mit Vorteil derart beschaffen, dass es die Folie 2 dem grösseren Teil des Haisrandes des Kunststoffbe¬ hälters entlang, nicht aber über die ganze Peripherie löst. Auf diese Weise wird verhindert, dass sich die Folie frei im Toner bewegen und gegebenenfalls mit diesem in den Einfüll¬ stutzen gelangen kann. Ferner ist die maschinenseitige Stutzenöffnung mit einem siebartigen Gitter 11 versehen, welches ein Eindringen von eventuell losgelösten Teilen der Tonerpackung oder anderen grösseren Fremdkörpern in den Printer verhindert. Das Element 5 kann z.b. aus einem vor¬ zugsweise zu Neunzehnteln seines Umfanges mit Zähnen ausge¬ statteten Ring bestehen. In diesem Fall sind (nicht darge¬ stellte) Mittel am Auslasshals des Behälters 1 und am Ein¬ lauftrichter 7 vorgesehen, die ineinander einrasten, z.B. eine Nocke am Auslasshals und eine entsprechende Nut am Ein¬ lauftrichter, um einen Verdrehschutz zu bilden und das irr¬ tümliche vollständige Lösen der Folie 2 zu verhindern. Es ist für den Fachmann klar, dass das Element 5 auch verschiedene andere bekannte Formen aufweisen kann.The element 5 for opening the attached toner pack is advantageously designed in such a way that it Foil 2 loosens along the larger part of the shark edge of the plastic container, but not over the entire periphery. This prevents the film from moving freely in the toner and possibly being able to get into the filler neck with it. Furthermore, the machine-side nozzle opening is provided with a screen-like grille 11, which prevents any detached parts of the toner pack or other larger foreign bodies from entering the printer. The element 5 can consist, for example, of a ring which is preferably equipped with teeth to nineteenths of its circumference. In this case, means (not shown) are provided on the outlet neck of the container 1 and on the inlet funnel 7 which snap into one another, for example a cam on the outlet neck and a corresponding groove on the inlet funnel, in order to form a twist protection and that is wrong Prevent ¬ ordinary complete loosening of the film 2. It is clear to a person skilled in the art that the element 5 can also have various other known shapes.
Im allgemeinen enthalten die gebräuchlichsten Packungen 1,8 kg Toner und weisen z.B. die äusseren Aus¬ messungen 85 x 185 x 490 mm auf. Die Grosse der Grundfläche und die Höhe der Packung ist im allgemeinen durch das Kopier¬ gerät begrenzt. Um einen optimalen Ablauf des Toners zu er¬ geben, beträgt das Verhältnis von Grundfläche zur Austritts¬ fläche mit Vorteil 1 : 4. Die Tonerpackung 1 wird bei Gebrauch mit dem Auslasshals 1' der durch die aufgeschweisste kunststoff¬ beschichtete Alufolie 2 luftdicht verschlossen ist, nach unten in den Einlauftrichter 7 des Einfüllstutzens 6 eingesetzt. Das am Einlauftrichter 7 befindliche Dich¬ tungselement 4 sorgt für einen staubdichten Abschluss zwischen' dem Einlauftrichter 7 und dem Halsstück 1 ' der Packung 1.In general, the most common packs contain 1.8 kg of toner and have, for example, the outer dimensions 85 x 185 x 490 mm. The size of the base area and the height of the pack is generally limited by the copier. In order to give the toner an optimal flow, the ratio of base area to exit area is advantageously 1: 4. When used with the outlet neck 1 ', which is sealed airtight by the welded-on plastic-coated aluminum foil 2, the toner pack 1 is inserted downwards into the inlet funnel 7 of the filler neck 6. The sealing element 4 located on the inlet funnel 7 ensures a dust-tight seal between 'the inlet funnel 7 and the neck piece 1' of the pack 1.
Sobald die Packung 1 tief genug eingesetzt ist, tritt sie mit dem gezahnten Element 5 in Berührung, das die Folie 2 mit Ausnahme eines Restes von ca. 2 cm vom Rand des Auslasshalses 1' löst, so dass der Toner ungehindert in den Einfüllstutzen 6 und in das Kopier¬ gerät ausfliessen kann. Die entleerte Kunststofflasche wird entfernt und der Einfüllstutzen mit dem Deckel 8 verschlossen, welcher mit einer Kette 9 am Einfüll¬ stutzen 6 befestigt ist. Auf diese Weise wird der staub¬ dichte Verschluss des Einfüllstutzens erzielt, der seiner¬ seits mit dem Kopiergerät verbunden bleibt. Die leere Flasche kann jedoch nach Beendigung des Einfüllens auch auf dem Einfüllstutzen belassen werden, um ihrerseits einen staubdichten Abschluss des Einfüllstutzens zu bilden. As soon as the pack 1 is inserted deep enough, it comes into contact with the toothed element 5, which, with the exception of a remainder of approximately 2 cm, releases the film 2 from the edge of the outlet neck 1 ', so that the toner flows freely into the filler neck 6 and can flow into the copier. The emptied plastic bottle is removed and the filler neck is closed with the lid 8, which is attached to the filler neck 6 with a chain 9. In this way, the dust-tight closure of the filler neck is achieved, which in turn remains connected to the copying machine. However, the empty bottle can also be left on the filler neck after the filling has ended, in order to form a dust-tight closure of the filler neck.
