Definitions

  • the invention relates to a device for guiding a printing unit according to the preamble of patent claim 1.
  • printer carriage which carries the actual printing unit.
  • the printer carriage is a self-contained assembly and is mounted on two guide rails parallel to the platen, i.e. moved back and forth along a line of a record carrier. The movement takes place via a traction means, for example via a toothed belt, which is connected to the printer carriage on the underside in a non-positive and positive manner.
  • the printing unit e.g. a print head, can either be an integral part of the printer carriage, or it can be connected to the printer carriage in an exchangeable manner.
  • a writing device of this type is described for example in DE-AS 22 32 590.
  • a printer carriage of the type described is a compact, structurally complex and relatively heavy structural unit, which, especially at high writing speeds, requires considerable forces when accelerating and braking the printer carriage.
  • the object of the invention is to provide a device for guiding a printing unit which is simple in construction, the weight and volume of which is considerably reduced, and in which the interchangeability of the actual printing unit is simplified.
  • the embodiment shows the parts of a writing device necessary for understanding the invention.
  • the device provided for guiding a printing unit 1 consists of a guide bush 2 and a holder 3 which is latched over it.
  • the guide bush 2 is plugged onto the guide rail 5 facing the platen roller 4 and moves in a sliding manner thereon.
  • the holder 3 has an extension 6 to which the traction means 7, in the example a toothed belt, is fastened.
  • a turnbuckle 8 is provided in the example.
  • the drive bushing 2 and the holder 3 are moved back and forth in front of the platen roller 4 in the line direction by means of drive elements (not shown here), for example by stepping motors.
  • the bracket also has locking openings that together with ent speaking, arranged on the printing unit locking pieces ensure a precise positioning of the printing unit in a simple manner.
  • the design of the guide bushing 2 as a bronze bushing with two sliding surfaces ensures that the guide bushing 2 runs with very little play on the guide rail 5, so that even high demands on the writing quality, which depend to a very considerable extent on very precise guidance of the printing unit are guaranteed.
  • a locking element in the form of a snap bracket 9 is used to fasten the printing unit 1 to the guide bush 2.
  • the snap bar 9 is held in a form-fitting manner with its cross bar in the printing unit 1, while its two legs are freely accessible on both sides of the printing unit.
  • the printing unit 1 provided with a fork-shaped guide projection 10 is first plugged onto the second guide rail 11 and positioned in relation to the holder 3.
  • the holder 3 has latching openings 13 and the printing unit 1 has correspondingly shaped latching pieces 14.
  • at least two locking openings and two locking pieces are provided in each case.
  • the latching pieces 14 engage in the latching openings 13 and are guided securely until the shaped part of the latching pieces 14, which is adapted to the shape of the guide bushing 2, is securely guided.
  • the printing unit 1 is thus securely and precisely positioned on the one hand by the guide projection 10 which is plugged onto the second guide rail 11 and on the other hand by the latching pieces 14 which are inserted into the latching openings 13 and locked there.
  • the snap bracket 9 attached to the printing unit 1 is then snapped over the guide bush 2. Due to this latching, there is a supportive frictional connection between the printing unit 1 and the guide bushing 2.
  • the double-acting non-positive locking connection by means of the snap bracket 9 to the left and right of the positioning ensures that the printing unit 1 is securely fixed in the previously set target position.
  • the printing unit 1 thus follows the movements of the guide bush 3 exactly.
  • the protruding end 12 of the snap bracket 9 enables simple and quick closing and releasing this connection and thereby facilitates the exchange of the printing unit. This is done in a simple manner by manually removing the snap bracket 9. After releasing the snap bracket 9, the printing unit 1 can be pivoted upward and pulled out of the second guide rail 11. Since the electrical connection between the control parts of the writing device and the printing unit 1 is made by means of a pluggable flexible cable, all that is still required is to release the plug connection. This very simple and very quick replacement of the printing unit allows, for example, an ink print head to be used instead of a wire print head.
