Definitions

  • the invention relates to a device for filling a Ink tanks, in particular a refill device for Filling ink tanks for ink jet systems, such as printers and plotter, or other automatic registration, Writing or drawing systems.
  • Refill devices for filling containers or ink tanks are known in principle. There are, for example, refill systems, for filling ink tanks for ink-jet systems and plotters or for other automatic registration, writing or drawing systems, with the help of which it is possible to replace the empty ink tanks of the printheads or recording pens with new ones Refill ink or other recording media.
  • an ink refill device in which an adapter is provided which is arranged on a print head and with the aid of which on the one hand the ink tank of the print head is opened and, in addition, a refill container is placed, pierced and fastened can be.
  • the closure parts When the container is opened or punctured, the closure parts are loosened or destroyed, so that the ink can then flow from the container into the tank.
  • the air equalization in the tank to be filled and via this in the refill container takes place via air channels that open into the open.
  • the refill container To fill the tank, the refill container must be arranged above or above the adapter so that the ink can flow automatically from the container into the tank due to gravity.
  • a disadvantage of such a device in the form of this adapter is that the adapter cannot be used to refill a hermetically sealed tank or a tank without permanently open air equalization due to the counterpressure that builds up.
  • the object of the invention is to provide a device for refilling ink tanks which does not have the disadvantages mentioned above and which offers the user an inexpensive, simple and clean possibility of refilling tanks which are difficult to refill, such as hermetically sealed tank systems.
  • the existing material such as empty tanks, with or without printheads, can be used again, which saves resources, reduces waste and, on the other hand, saves costs for the user.
  • FIG. 1 shows the basic structure of a proposed device, an ink tank 2 to be refilled and a refill container 3 containing the ink supply being inserted into an adapter 1.
  • the adapter 1 is shown as a separate part from the front or from the side to which the ink tank (2), not shown here, is connected.
  • a tank connection 12 is arranged on the distributor housing 11 of the adapter 1 as a plug connection.
  • the tank connection 12 consists of a connection body 121, as well as a filling connection 123, with a tank cannula 142 and an air connection 124, with an air cannula 151.
  • a refill container (3) not shown here, can be inserted into the connection housing 131 at the container connection 13.
  • Guide grooves 132 are provided on the side of the connection housing 131, into which centering lugs or cams of the refill container (3) can engage, for example to identify the togetherness of defined filling systems. If the adapter is to be suitable for a specific ink or device type, the shape and position of the arrangements may have to be designed differently.
  • FIG. 3 the filling situation is depicted in which a refill container 3 is inserted in or on the distributor housing 11 of the adapter 1 and an ink tank 2 is pushed.
  • the tank mouthpiece 23 of the ink tank 2 is placed on the tank connection 12 of the adapter 1 and connected to its filling connection 123 in a friction-locked manner.
  • the reserve ink flows as refill means 300 via the filling system 14, or via the container cannula 143, the filling channel 141 and the tank cannula 142 into the tank reservoir 22 of the ink tank 2, as reusable writing means 200 from there.
  • the tank cannulas are located in the filling channel 141 142 and on the container side, the container cannula 143 is firmly inserted, which penetrate the tank seal 212 in the tank mouthpiece 23 and the container seal 322 in the container sleeve 321 by means of piercing tips or pressure bevels and thus enable the continuous flow of ink.
  • the ink reservoir 22 lies within the tank housing 21, in the hermetically sealed tank chamber 211, delimited by the storage sleeve 221. So that during the refilling process the soft filling container 32 delimited by the container sleeve 321 in the container housing 31 can collapse unhindered during emptying, there are at least in the container housing 31 a container opening 312 for ventilation of the container space 311 is arranged.
  • FIG 4 shows the device acc. Figure 3, with the adapter 1, the ink tank 2 and the refill container 3, here a section through the ventilation system 15 is made, according to line BB in Figure 2.
  • the ventilation system 15 integrated in the distributor housing 11 here has a firmly inserted towards the ink tank 2 Air cannula 151 and creates a free passage to the environment via an air opening 152. This creates pressure equalization to the atmosphere and during the filling process, the same amount of air escapes from the otherwise hermetically sealed tank space 211 of the ink tank 2 as the refilled amount of the refill 300 from the fill container 32 takes up volume in the ink reservoir 22 as a newly available writing medium 200.
  • the air cannula 151 penetrates the air seal 213 which is fixedly arranged in the air mouthpiece 24 and thus opens the otherwise hermetically sealed tank space 211 in the ink tank 2. While the ink tank 2 is connected to the distributor housing 11 of the adapter 1 in a frictionally but detachably manner via the tank connection 12 , the container housing 31 of the refill container 3 is located, sealed but relatively loosely seated, in the connection housing 131 of the container connection 13.
  • the proposed device for filling an ink tank in particular an ink reservoir in an ink jet system, a printer, plotter or other automatic Registration, writing or drawing system, has one Refill container (3) and the ink tank (2) is with this is connected by an adapter (1) and in the filling position arranged essentially one above the other.
  • the adapter points at least two connections for the containers to be connected 3 and tanks 2 on and in the ink tank 2 is an ink reservoir 22 arranged, between the tank housing 21 and the Ink storage 22 a hermetically sealed tank room 211 is formed.
  • the adapter 1 designed and dimensioned in this way be with a refillable ink tank 2 and a suitable refill container 3 in the filling position, that is, in the assembled state, one in itself contains or forms hermetically sealed filling system 14 and has an additional air system 15.
  • the filling system 14 has at least one tank cannula 142, arranged in a filling channel 141, and a container cannula 143 which, when the ink tank 2 is connected and when the refill container 3 is inserted in the filling position, has a fluidic connection between the interior of the filling container 32 and the Ink storage 22 forms.
  • the air system 15 should preferably have an air cannula 151 which, in the filling position, possibly via an air opening 152, forms an air passage between the interior of a hermetically sealed tank space 211 and the atmosphere.
  • the adapter 1 is a rigid, rigid distribution housing 11 and at least one such tank connection 12 and / or container connection 13 and if the Ink tank 2 and / or the refill container 3 also out solid or rigid material the whole device is particularly stable and easy to handle.
  • the sealing elements 212, 213, 322 are intended to be on the ink reservoir 22, in the ink tank 2, in the refill container 3 and / or in the Connection areas of the adapter 1 itself should be arranged and during the refilling process between the Sealing elements 212, 213, 322 and those in adapter 1 arranged cannulas 142, 143, 151 at least one each sealing connection be formed.
  • cannulas 142, 143, 151 at least one each each have a rigid piercing tip associated closure on the ink tank 2 and / or on Refill container 3 is particularly easy and easy to open.
  • the Ink storage 22 of the ink tank 2 and / or Filling container 32 of the refill container 3 is easy deformable sheath 221, 321, e.g. the Storage sleeve 221 and / or the container sleeve 321 from one flexible, elastic material, preferably made of one highly flexible polymer material should exist.
  • the sealing elements 212, 213, 322 can or should Rubber or soft plastic and as discs or rings and / or be designed as self-firing valves.
  • the connecting means on the tank connection 12 and / or on Container connection 13 of the adapter 1 should complementary to the ink tanks 2 and Refill containers 3 as plug connections, positive Connections or be designed as threaded connections.
  • a device was created that can be used as Adapter 1 a fluid connection via a filling system 14 between a refillable ink tank 2 and a Refills container 3 via coupling elements.
  • a filling system 14 between a refillable ink tank 2 and a Refills container 3 via coupling elements.
  • the liquid level of the Refill container 3 above the level of the ink tank 2, so the refill process takes place by gravity.
  • a pressure equalization or an opening of the hermetically sealed tank space 211 which between the outer surface of the ink reservoir 22 and the Inner surface of the tank housing 21 lies to the atmosphere getting produced.
  • This connection is made via a Ventilation system 15 in the adapter 1.
  • the adapter 1 thus simultaneously fulfills the functions of establishing a fluidic connection and creating an air balance.
  • the connections are sealed with sealing elements 212, 213 and 322, such as with septa or valves.
  • These sealing elements 212, 213, 322 are pierced by the cannulas 1142, 143 and 151 when the refill container 3 with the fill container 32 and the ink tank 2 with the ink reservoir 22 are docked onto the adapter 1. If, after the refilling process, the filled ink reservoir 22 and the emptied or only partially emptied filling container 32 are separated or removed from the adapter 1, the sealing elements 212, 213, 322 automatically close as soon as the coupling elements are removed.
  • the container connections 13 of the adapter 1 can have elements such as guide grooves 132, which correspond to corresponding elements on the refill container 3 or act together on the ink tank 2, such as noses or cams, for example according to the so-called tongue and groove principle.
  • the refilling process should expediently begin by first connecting and opening the empty ink tank 2 securely with the adapter 1, and then inserting and opening the refill container 3.
  • the fill quantities of ink tank 2 and refill container 3 should be coordinated with one another in such a way that the contents of the refill container 3 can be completely filled into the ink tank 2 during a filling process. Otherwise shut-off valves or other portioning aids and / or content and filling indicators should be attached.
  • the three components adapter 1, Ink tank 2 and refill container 3 - preferably through vertical trigger movements - separated from each other again.
  • the three advantageously close here Seals 213, 212, and 322 - if possible also in this Sequence - automatically air and liquid tight. If - with the same connection lengths of the tank mouthpiece 23 and the air mouthpiece 24 - the free contact length of the Air cannula 151 is shorter than the free connection length of the Tank cannula 142 becomes a relatively contamination-proof release of the ink tank 2 in the specified closing sequence enables when the ink tank 2 in front of the refill container 3 Will get removed.
  • 1 adapter 11 Distributor housing, 12 Tank connection (here as plug connection), 121 Connection body, 123 filling connection, 124 Air connection, 13 Container connection (plug connection), 131 Connection housing, 132 guide, 14 filling system, 141 filling channel, 142 Tank cannula 143 Container cannula 15 Air system, 151 Air cannula 152 Air opening, 2 ink tank 200 Ink / writing medium (in 22), 21 Tank housing 211 Tank room (hermetically sealed), 212 Tank Seal, 213 Air seal, 22 Ink reservoir, 221 Storage cover, 23 Tank mouthpiece 24 Air mouthpiece; 3 refill 300 Refill agent (in 32), 31 Container housing, 311 Container space, 312 Container opening, 32 Storage capacities, 321 container shell 322 container seal
