Definitions

  • the invention relates to a needle printhead according to the preamble of claim 1.
  • the hinged armature is suspended at its radially outer end on a spring clip and rests on the radially outer yoke leg in such a way that it can be tilted around the radially outer edge of the yoke leg surface facing it.
  • a first disadvantage of this solution is that the yoke leg and the hinged armature resting against it rub against one another during the movement of the latter, as a result of which a relatively strong and undefined wear of the abutting surfaces occurs. As a result, the quality of the print image of such a needle printhead changes after a long period of operation.
  • a folding armature magnet for a printer is also known from US Pat. No. 4,202,638, in which the folding armature is fastened to a leaf spring with its end facing away from the printing end.
  • the hinged anchor rests in its rest position on the magnetic yoke, the leaf spring being tensioned so that the KIappanker strikes the record carrier under the action of the leaf spring.
  • the folding anchor is mounted on the one yoke leg about a fixed pivot axis, a return spring acting on its short lever arm remote from the printing needle. Because of this unfavorable leverage ratio, the hinged anchor also has the disadvantages discussed above. Furthermore, in this embodiment, the hinged anchor is not firmly connected to the pressure needle, but strikes the pressure needle biased into its rest position by its own return spring. Since the pressure needle, on the one hand, and the hinged armature, on the other hand, represent two oscillating systems that do not have identical oscillation sizes, the oscillation behavior of the two oscillation systems can be significantly different at suitable operating frequencies. On the one hand, this can lead to increased wear on the pressure needle and the hinged anchor and, on the other hand, it can produce silhouettes.
  • a needle print head of the type described in the preamble of claim 1 is known, in which the bearing forks are attached to radially protruding fingers of a frame.
  • the bearing forks have an approximately semi-cylindrical recess at their end opposite the fingers, into each of which a cylindrical pin of the radially outer end of a folding anchor can be inserted.
  • the frame is covered with a non-magnetic plate so that each bearing fork with a hinged anchor located therein is opposite a tab of the plate. This means that each folding anchor is held in its storage fork.
  • the frame is attached to the yoke plate in such a way that each bearing fork with the hinged armature magnet located therein is arranged opposite one another.
  • FR-A-2,026,401 shows a rod of an accelerator, brake or clutch pedal of a motor vehicle.
  • the rod is clipped into bearings that are held in L-shaped brackets.
  • the invention has for its object to provide a needle print head of the type mentioned, which is easy to manufacture and assemble.
  • the folding anchor has a spatially fixed, defined pivot axis.
  • the cylindrical pins are easy to use manufacture very precisely.
  • the abutting bearing surfaces of the pin on the one hand and the plastic bearing parts receiving it on the other hand are subject to low wear and tear, which is also carried out at least approximately in the same size and in the same way for all hinged anchors.
  • the elasticity of the plastic allows the pin to be clipped in. This means that the hinged anchor can be quickly installed without careful adjustment. At the same time, the plastic ensures little wear on the bearing pin.
  • the storage forks can be easily and precisely manufactured as injection molded parts.
  • a return spring preferably engages at a point of the hinged armature located between the pressure needle and the radially inner yoke leg. Since, in the solution according to the invention, the hinged armature is designed as a one-armed lever and the return spring acts on the hinged armature relatively far from the bearing axis, tolerances in the spring strength or in the distance of the point of application of the spring on the hinged armature from the bearing axis affect the impact force of the pressure needle hardly out. Therefore, the impact force of various new hinged anchors in the solution according to the invention is within a very narrow tolerance range.
  • the needle print head according to the invention thus provides a very uniform typeface. Because of the arrangement of the return spring relatively close to the pressure needle, the rebound of the hinged armature against the stop is also reduced, so that the danger of creating silhouettes at high operating frequencies is avoided.
  • the mounting of the bearing forks on the magnetic yoke can be done in a simple manner in that the bearing forks are connected to one another by a metal web which is attached to the radially outer yoke leg, for example by spot welding.
  • the return spring is preferably formed by a helical compression spring, which is supported on the one hand on a plate carrying the magnetic yokes and on the other hand on the respective hinged anchor, the helical compression spring advantageously being guided in a tube and for reducing the friction between the spring and the hinged anchor on the hinged anchor facing end carries a ball which engages in a spherical recess in the hinged anchor.
  • the stop common to all hinged anchors is adjustable in the direction of movement of the pressure needles.
  • the stop can wear a layer of a suitable damping material on its side facing the hinged anchors.
  • the mounting of the folding anchor according to the invention has the advantage over mounting the folding anchor on a spring that a defined air gap between the folding anchor and the magnetic yoke can be precisely maintained. This can reliably prevent the hinged anchor from sticking to the magnetic yoke.
  • FIG. 1 comprises a circular disk-shaped yoke plate, generally designated 10, with a central recess 12 into which a tubular central extension 14 of a disk-shaped heat sink 16 engages, on which the yoke plate 10 is fastened and which is attached to the yoke plate 10 opposite side fins 18 carries.
  • a schematically indicated mouthpiece or guide piece 17 for guiding printing needles 19 is held in the attachment 14.
  • the yoke plate 10 On its side facing away from the heat sink 16, the yoke plate 10 carries a plurality of folding armature magnets 20 in a circular arrangement around the central recess 12.
  • Each of these folding armature magnets comprises two yoke legs 22, 24, which are arranged next to one another in the radial direction and are formed integrally with the yoke plate 10 and oriented perpendicularly thereto
  • the radially inner yoke leg 22 each carries a magnetic coil 26.
  • the magnetic circuit is closed by an essentially radially directed hinged armature 28, to the inner end of which the pressure needle 19 is fastened.
  • the hinged armature 28 carries a cylindrical pin 30 which is mounted in a bearing part, generally designated 32, which is fastened to the radially outer yoke leg 24 and is explained in more detail with reference to FIGS. 2 and 3.
  • the hinged anchor 28 can thus be pivoted about the axis of the cylindrical pin 30 between the pressure position near the yoke leg shown in FIG. 1 and a position remote from the yoke leg, into which it is held by a helical compression spring 34 is tensioned and in which it rests on an annular stop 36.
  • the helical compression spring 34 is supported with its one end on a pin 38 formed in one piece with the yoke plate. At its end facing the hinged anchor 28, the helical compression spring 34 carries a ball 40 which engages in a hemispherical recess 42 on the underside of the hinged anchor 28 so as to reduce the friction between the spring 34 and the hinged anchor 28.
  • the stop 36 carries on its side facing the hinged anchors 28 a ring 44 made of a material which dampens the impact of the hinged anchors, in order to prevent the hinged anchors 28 from rebounding from the stop 36.
  • the annular disk-shaped stop 36 can be fastened to the yoke plate 10 with the aid of screws 46 which engage in threaded bores 48 which are provided in extensions 50 formed in one piece with the yoke plate 10. With the aid of spacer sleeves 52 surrounding the screws 46, the distance of the stop 36 from the yoke plate 10 and thus the pivoting path of the hinged anchors 28 can be set precisely.
  • the bearing part 32 has two storage forks 54 made of plastic, which are connected to one another by a metal web 56 in such a way that they are at a distance from one another which corresponds approximately to the width of the yoke leg 24.
  • the metal web 56 is fastened, for example, by spot welding to the radially outward-facing surface of the yoke leg 24, so that the two bearing forks 54 lie on both sides of the yoke leg 24, as can be seen in FIG. 2.
  • the bearing forks 54 point radially outwards with their fork opening and close a partially cylindrical one between them Bearing surface 58, which extends slightly over 180 °.
  • the opening width of the fork openings is slightly smaller than the diameter of the cylindrical pin 30 fitting into the bearing surfaces 58.
  • a printhead with hinged armature magnets designed in this way achieves a long service life with a high-quality print image, does not provide any shadow images even at high working frequencies, and is also suitable for printing on copy sets due to the high achievable impact force of the print needles.
