Definitions

  • the invention relates to a writing carriage for ink writing devices comprising a carrier part, a writing head arranged on the carrier part with an exchangeable storage container for the writing liquid and a filter unit arranged between the storage container and the writing head.
  • Such a writing head is used in the context of a typewriter, it can be favorable to design the writing head so that it can be lowered below the writing point, if necessary, in order to facilitate the view of the writing point. In this case, an elastic connection between the storage container and the writing head is necessary. Such a connecting element is accessible from the outside and can therefore be damaged.
  • the object of the invention is to provide a writing carriage of the type mentioned at the outset for an ink writing device, in which the ink is guided as directly and safely as possible from the ink supply bottle via a filter device to the writing head.
  • the writing trolley should be as simple and reliable as possible with a small mass.
  • the carrier part is trough-shaped at least in the area of the storage container and has guide elements in this area for jointly receiving the filter unit designed as an independently usable filter unit and the storage container which can be placed on the filter unit.
  • the filter unit is designed as a filter unit that can be used independently, it can be easily manufactured and easily replaced in the event of a fault.
  • the filter unit can also be produced in a simple manner from plastic from injection molding and in turn can be assembled simply by pressing together a metal ring.
  • the transition point between the ink reservoir of the filter unit and the connecting hose between the filter unit and ink writing head is within a dense trough of the carrier part, possibly escaping ink collects in this carrier part, so that there is no damage to the writing device.
  • the approximately constant cross-section of the connection system between the print head and the filter is easy to manufacture on the one hand, on the other hand it prevents the formation of gas bubbles within the supply system.
  • the separation of carrier part and filter unit enables each part to assign the optimal material.
  • the carrier part can be made from unbreakable glass fiber-reinforced plastic, but the filter unit can be made from an ink-tight thermoplastic.
  • the writing carriage shown in FIG. 1 for an ink mosaic writing device with piezoelectrically operated writing nozzles is moved line by line along a recording medium via a drive device, not shown here, via guide elements.
  • the writing carriage consists of a carrier part 1 made of glass fiber reinforced plastic, a pivotable writing head 2 arranged thereon, a filter unit 3 and not shown here, an exchangeable ink supply container arranged on the filter unit.
  • the side parts 4 of the carrier part 1 are pulled up, the carrier part 1 being designed like a trough in the region of the storage container.
  • guide elements 5 are provided for receiving the filter unit 3 see.
  • the guide elements 5 serve at the same time as a holder for the ink reservoir, which is designed to be exchangeable and is simply attached to the filter unit 3.
  • the filter unit consists of a lower part 6 having a trough-like filter space with connection elements, namely a connector 7 for the connecting tube 8 between the filter unit and the write head 2; Furthermore, from an arranged on the lower part 6, connecting element for ink supply to the reservoir, namely a hollow needle 9, having upper part 10 and a filter element 11 arranged between the lower and upper part.
  • This filter element separates the actual filter space into a lower one the ink supply containers via the hollow needle 9 connected settling space 12 and into an upper space 13 connected to the connecting tube 8. So that the ink can flow through the filter unit in the dashed manner shown in the drawing in FIG. 2, there is a circular distribution element 14 provided with a longitudinal slot on the bottom of the lower part 6.
  • the filter disc with the associated passage opening 15 is located on this distribution element 14 and forms the inflow channel from the hollow needle 9 to the settling chamber 12 in connection with the circular top piece 17 provided with sealing elements 16 and the sealing element 16.
  • the filter plate 11 is also fixed by a support ring 18 on the edges of the lower part 6.
  • An O-ring 19 is attached as a seal between the upper and lower part.
  • the upper part has a guide area 20 for the rubber stopper, which is not shown here, and which seals off the ink supply bottle Hollow needle 9 pierces this plug.
  • the entire upper part including the hollow needle 9 is injection molded from a single plastic element. The same applies to the lower part 6 with the distribution element 14.
  • a pressed-on metal ring 21 holds the individual elements of the filter unit together in a simple manner.
  • the filter unit 3 is fastened in the guide elements 5 of the carrier part 1 via an expansion ring 22.
