Abstract

ink printers with a replaceable collecting vessel (2), in particular a collecting vessel (2) for cleaning ink with an outlet opening (10) for Air and with an internally arranged, absorbent medium (3), the one with a sealing body (7) closed or closable inlet opening (4) is opposite, the approximately coaxially to a stored in the printer chassis, hollow piercing needle (5) runs, wherein with the insertion of the collecting vessel (2) an exit point (5a) for ink, Ink bubbles u. Like. At the hollow piercing needle (5) in contact with the absorbent, yieldable medium (3) is characterized in that the air through outlet openings (10) in the sealing body (7) around the piercing needle (5) around the collecting vessel (3) derivable is.

Description

  • The The invention relates to an ink printer with a replaceable Collecting vessel, in particular a collecting vessel for dirty ink with an outlet opening for air and with an internally disposed, absorbent medium, the one with a sealing body opposite closed or closable inlet opening, the approximately co-axial with a stored in the printer chassis, hollow Piercing needle runs, wherein with the insertion of the collecting vessel an exit point for ink, Ink bubbles u. Like. At the hollow piercing needle in contact with the absorbent, compliant medium is displaceable.
  • In Ink printers, it is necessary when commissioning the nozzle heads and to maintain the nozzle function Ink through the nozzle head to suck or to press. The case from the nozzles escaping ink must be collected become. With water-based inks, these ink residues become one fed to porous sponge, in which the ink evaporates. For oil-based inks, evaporation takes place not, therefore you have to such inks are collected in a removable receptacle. In which flushing a mixture of ink and air (in the ratio of about 1:10) is aspirated and supplied to the collecting vessel.
  • At the respective exit point, which consists of an opening of a suction hose a piercing needle o. The like. Can exist, forms the air-ink mixture Bubbles, similar Soap bubbles. Such bubbles also pass through ink tanks Vent off and pollute the contact area of the nozzle head and the entire printer.
  • The initially designated ink printer is known from WO 99/1146 A1 or in translation from the EP 0 928 694 A1 known. At the contact point medium / ink transverse openings are provided so that the air contained in ink bubbles can dissolve and escape. However, it is not possible that the air could escape through an opening provided at the tip of the hollow needle. Rather, there is the danger that the tip of the hollow needle is closed when inserting into the absorbent medium with the increase of the feed. This tirelessness is avoided by employing a 2-needle system with an ink feed needle and a debris needle placed side by side separately.
  • From the US 5 742 308 A and the EP 0 685 339 A2 In each case, an ink printer with a collecting vessel is known, in whose connection piece or in the sealing body an air outlet opening is provided, but this is arranged separately from the inserted hollow needle and the refilling or for a special filling device, so that the cost is very high, serves other purposes and the production can not be economical.
  • Of the Invention has for its object to avoid ink bubbles, to recover the ink contained therein or at least to bind and to separate the air.
  • The asked task is in the initially designated ink printer according to the invention thereby solved, that the air passes through outlets in the sealing body around the piercing needle around is derived from the collecting vessel. Have attempts shown that such exit points the ink bubbles are avoided by the ink from the absorbent medium recorded and the air is released to the environment. The air can therefore through vents escape from the collecting container without blistering.
  • To an advantageous embodiment is proposed that in the Axis of the hollow piercing needle in the receptacle a connector used is that the absorbent Directed medium forms a cavity into which the absorbent medium protrudes. In the cavity can be an absorbent ring be used, in intimate contact with the absorbent medium stands. The ring can also be made in two parts, resulting in a Easy assembly results. The absorbent ring allows an application the principle of such ink containers in which the medium in a larger area surrounding the piercing needle. The ring also makes contact with the outlet openings the hollow piercing needle increases.
  • advantageously, is the absorbent medium from a large pore Sponge made of PUR, a fleece made of cellulose or a felt mat.
  • Further Such an embodiment is proposed that the collecting vessel the ink printer chassis solvable is assigned and that by removing the exit point by means of a sealing sleeve and the bottom lockable is.
  • A another arrangement is that the collecting vessel a the nozzle head detachable carriage assigned and that by Remove the exit point by means of the sealing collar and its Floor closable is.
  • In the drawing are embodiments of Invention shown and will be explained in more detail below.
  • It demonstrate:
  • 1 a cross section through an ink printer chassis with receptacle in position before piercing,
  • 2 the same cross-section as 1 able after piercing,
  • 3 a horizontal section through a stationary ink cartridge housing and
  • 4 a vertical section through the stationary ink cartridge housing.
  • The inkjet printer has an inkjet printer chassis 1 on with a replaceable collecting vessel 2 , in particular, a collecting container for dirty ink, wherein inside 2a of the collecting vessel 2 an absorbent medium 3 is provided, that of a closed or closable entrance opening 4 which is approximately co-axial with an inkjet printer chassis 1 stored, hollow piercing needle 5 runs.
  • According to the 1 and 2 is with the insertion of the collecting vessel 2 an exit point 5a for ink, ink bubbles u. Like. At the top of the hollow piercing needle 5 and a contact created with the absorbent, compliant medium 3 , which may consist of a large-pored sponge made of PUR, a non-woven cellulose or a felt mat. The hollow injection needle 5 dives into the absorbent medium 3 one. The embodiments of the 1 and 2 see in the axis 5b the hollow piercing needle 5 in the collecting vessel 2 a sealing collar 4a before with a preformed, against the absorbent medium 3 directed ground 4b , Once the relative position of the hollow piercing needle 5 in 2 is achieved, a separation of air and ink takes place, the air is released into the environment and the ink in the medium 3 remains. This process takes place at a contact point 5c between medium 3 and ink instead.
  • According to the 3 and 4 is alternatively in the axis 5b the hollow piercing needle 5 in the collecting vessel 2 a connector 6 used that to the absorbent medium 3 executed a mounting flange 6a for a bag 8th forms, wherein the connection piece 6 at the entrance 6b a sealing body 7 is arranged. The sealing body 7 forms around the piercing needle 5 around outlet openings 10 through which the air can escape as long as the piercing needle 5 is introduced.
  • The mounting flange 6a also forms a cavity 6c towards the absorbent medium 3 that this cavity 6c largely completed.
  • The collecting vessel 2 can be out of a bag 8th exist in an ink cartridge housing 9 is introduced and removed after consumption of the ink.
  • In the connector 6 and / or in the sealing body 7 are the outlet openings 10 provided, which are cuff-like around the outer circumference of the piercing needle 5 and leave gaps through which the air can escape.
  • Alternative embodiments also result from the fact that the collecting vessel 2 the ink printer chassis 1 is assigned releasably, wherein by removing the collecting vessel 2 the exit point 5a is automatically closed.
  • The collecting vessel 2 but can also be associated with a nozzle carrying the nozzle releasably and when removing is also the exit point 5a automatically closed.
