Definitions

  • the present invention relates to a device for filling toner into a copier, in particular a laser copier.
  • 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.
  • 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.
  • the invention further relates to a method for operating the new device, which is defined in claim 5.
  • 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 can be operated by the filling device.
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • means 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.
  • the element 5 can also have various other known shapes.
  • 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.
  • the ratio of base area to exit area is advantageously 1: 4.
  • the pack 1 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.
  • 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.

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).
