Definitions

  • the invention relates to a device for cleaning a print head of an inkjet printer according to the preamble of claim 1.
  • Out DE 200 12 946 U is a printer-internal service facility known.
  • the print head is pivotally mounted in the printing unit, wherein it is movable in different predetermined angular positions. These angular positions correspond to various service positions such as a lock position, a wiping position, a wiping position and an ink collecting position.
  • This service device is coupled to the printer and also requires a relatively large amount of space.
  • EP-A-0'671'273 discloses a cap for a printhead which can be folded from an open to a closed position.
  • DE-A-196'09'879 describes a storage container for a printhead having a cap of a resilient material to protect the nozzle openings from drying out.
  • EP-A-900'661 shows a storage container for multiple printheads. The storage container has cleaning agents that clean the printheads the same when inserted into the container.
  • JP 08244247 describes a storage container for a printhead, the container having an absorbent body impregnated with an ink solvent or with water.
  • a holder for receiving the print head in which an absorbent element for cleaning the nozzle plate and / or the electrical contacts is arranged. Furthermore, the holder has a sealing element which seals a nozzle plate of the print head.
  • the holder has at least one movable member, so that it can be switched from a position for parking and / or transport of the print head in a cleaning position for cleaning the nozzle plate.
  • the absorbent element is arranged on a movable first carrier, so that the print head remains in the holder for cleaning.
  • the holder has a cleaning element for cleaning the electrical contacts, which is arranged on a movable carrier.
  • the cleaning element for the nozzle plate is designed as a cushion, which can be drizzled with a cleaning liquid.
  • the print head is removed from the holder for cleaning and the nozzle plate is moved over the pad.
  • the device after the FIGS. 1 to 4 has a holder 1, in which a print head 2 is snapped.
  • the holder 1 has two narrow side walls 10 centering in the form of protruding pins 11, in which semicircular recesses 12 of the printhead 2 engage.
  • a resilient latching lug 13 is formed, which is engaged in a latching shoulder 14 of the head 2.
  • the rear wall 15 of the holder 1 has a circular recess 16 which has a rectangular extension 17 at the bottom. From the lateral edges of this extension 17 are from pin 18, are snapped on a little more than half-round recesses 19 a round flap 20.
  • the flap 20 also has a rectangular projection 21.
  • a sealing lip 23 is inserted with a circumferential elastomeric or elastic bead, wherein the sealing lip 23 with the flip down flap 20 and inserted head 2, the periphery of the nozzle plate 24th of the head 2 airtight concludes.
  • the sealing lip is designed rectangular. Other shapes are possible.
  • the sealing of the nozzles of the nozzle plate can be ensured over a long time.
  • This position of the flap 20 is suitable therefore, for shipping the printhead and parking it when not in use so that the ink in the nozzles of the nozzle plates 24 does not dry out.
  • an elastomeric plate is expediently inserted into the sealing lip 23 for transport, which bears on the nozzles in a planar and sealing manner.
  • the nozzles can also be closed by means of an adhesive strip.
  • a plate 31 designed as a carrier is inserted on the bottom 30 of the holder 1.
  • the plate 31 is preferably round. It is snapped with two central, downwardly projecting hooks 32 in an opening 33 of an integrally formed on the bottom 30 spring arm 34.
  • an absorbent element is used for cleaning the nozzle plate.
  • it is an elastic washer 36 which is slightly wetted with a cleaning fluid.
  • the washer 36 may for example consist of an open-cell, elastomeric foam. In the case of water-soluble inks, the cleaning liquid consists predominantly of water.
  • the disk or the foam body 36 can also consist of two layers of different pore size, wherein only the lower layer wets and the upper layer is dry in the unloaded state.
  • the lower layer thus has the greater capillarity (narrower pores).
  • This variant has the advantage that rapid evaporation of the cleaning liquid is prevented.
  • the head 2 is first removed from the holder 1, the flap 20 in the position after FIG. 2 folded up and the head 2 inserted again.
  • the plate 31 can be pushed up manually ( FIG. 3 ), where he diametrically opposite the Nozzle plate 24 abuts against a stop 37, so that the plate 31 is exactly parallel to the nozzle plate 24.
  • the movement of the plate 31 may also be limited on the opposite side by stops, so that the disc 36 is pressed against the nozzle plate 24 with a defined pressure.
  • the plate 31 can also be easily rotated during cleaning.
  • the plate 31 is rotated slightly further between successive cleaning steps.
  • FIGS. 5 to 14 Analog parts are provided with the same reference numerals, so that a detailed description of these parts is unnecessary.
  • the carrier or plate 31 is rotatable in steps and locked with locking elements each in one of these rotational positions.
  • the locking elements consist of an integrally formed on the holder 1 spring arm 45 with a notch 46, in which locking cams 47 engage on the outer circumference of the plate 31.
  • the plate 31 is divided into several areas 48. In one of these areas 48, the recess 22 is formed, in which the sealing lip 23 is fixed. In the other areas 48 wetted with cleaning liquid foam plates 49 are used to clean the nozzle plate. Under each of these plates 49, the plate 31 has a through opening 50. A further opening 51 is located in the bottom 30 of the holder 1 below the nozzle plate 24. In the in FIGS.
  • the plate 31 is rotatable in three positions, namely one for shipping, one for parking and one for cleaning the nozzle plate.
  • a lever 52 is formed on the plate 31.
  • the sealing lip 23 is attached. This serves to park the head 2.
  • a specially designed for the transport seal 54 is used, for example, the entire surface of the nozzle plate 24 rests and closes the nozzle.
  • the foam plate 49 is used for cleaning the nozzle plate.
  • the circumferential sealing lip 23 is inserted directly in the bottom 30.
  • the cleaning element is designed as a cushion 36 and used in addition to the sealing lip 23 in a recess 60 of the bottom 30.
  • the printhead 2 is removed from the holder 1, and a few drops 61 of cleaning liquid are dropped on the pad 36.
  • the cleaning of the nozzle plate 24 by slight pressing and reciprocating on the pad 36 ( FIG. 9 ). If, after a long period of inoperative use, the ink should have dried in the nozzles of the nozzle plate 24, one or two drops of cleaning liquid 61 are introduced into the recess 62 of the sealing element 63 enclosed by the sealing lip 23 ( FIG.
  • the printhead 2 is inserted into the holder 1 and turned upside down ( FIG. 11 ). Subsequently, the print head 2 is removed from the holder 1, the nozzle plate 24 is wiped on the pad 36 ( FIG. 12 ) and the printhead is reinstalled in the holder 1 or directly in the printer.
  • the centering on the holder 1 for the printhead 2 may be formed the same as in the embodiments, for example FIGS. 1 to 6 ,
  • FIGS. 13 and 14 show an embodiment in which in a circular opening 66 of the rear wall 15, a carrier or plate 67 is rotatably inserted.
  • a cleaning element made of an absorbent material is attached, which is also preferably porous and elastic.
  • the cleaning element is a disc 68, such as a sponge, mounted analogous to the disc 36 of the first embodiment.
  • the rear side has a handle 69 for manually rotating the plate 67.
  • the carrier is designed as a slide which can be moved back and forth in the vertical direction.
  • it is rectangular in shape.
  • the embodiment according to the FIGS. 13 and 14 can also be used with the mobile carriers according to FIGS. 1 to 7 Mistake.
  • this embodiment can also be designed as a holder, which does not have a cleaning element integrated in the holder for cleaning the nozzle plate, but comprises only an integrated cleaning element for cleaning the electrical contacts.
  • the sealing element 23 effectively protects the nozzles from drying out and from mechanical damage.
  • the sealing element 23 can be used interchangeably, so that the holder can be used for different print heads.
  • the foam body 36 allows a gentle but effective cleaning of the nozzle plate. If the ink is very dry, it is also possible to specifically treat only the nozzle plate.
  • the cleaning pad 36 can be turned over or reused for heavy use if heavily soiled be replaced with a new cleaning pad.
  • the polishing pad 68 can be easily eliminated by simply back and forth turning light oxide layers and grease and ink residue on the electrical contacts of the printhead.
