Definitions

  • the invention relates to a ribbon printing unit according to the preamble of patent claim 1.
  • Such a ribbon printing unit is known from FR-A-2 164 349.
  • the individual type tapes can be adjusted by turning the respectively assigned setting wheel so that the desired print types on the type tape outer surfaces reach a certain printing position.
  • the setting wheel is turned, the type band is carried along by the setting wheel, and the associated star wheel, around which the type band is also guided, rotates around its axis.
  • a print type on the type tape is in the print position when it is on the circumferential surface of the switching star facing away from the setting wheel.
  • print types of several type bands arranged side by side must be brought into the printing position.
  • each switching star is assigned two elastic spring tongues which are formed in one piece on a holding block and are independent of one another and each extend with their free ends in opposite directions.
  • a switching star corner first acts on one of the spring tongues at a point where it is relatively stiff, since the point lies close to the connection point with the holding block. This means that a relatively large force must be overcome when the star wheel is initially rotated. If the switching star reaches an intermediate position approximately in the middle between its two end positions during twisting, then the force exerted on it by the spring tongues is considerably smaller, since the switching star corner in this intermediate layer interacts with the free ends of the spring tongues. In order to finally move the switching star to its next end position, a higher force must be applied again, since the relevant switching star corner now interacts again with the other spring tongue at a point where it is relatively rigid.
  • the known design of the inhibiting device for the switching star is also disadvantageous for manufacturing reasons.
  • the opposing and finger-like interlocking spring tongues can only be manufactured in a complicated injection mold, in which a core must be inserted before each injection process.
  • a complicated material to be molded makes the production of injection molded parts considerably more expensive.
  • the invention has for its object to provide a simply constructed inhibitor for the switching star of a ribbon printing unit, which is designed so that the operator is very easy to position the exact types of printing.
  • the spring tongue used for each switching star in the belt printing unit according to the invention exerts, due to its arrangement and configuration when the associated switching star is rotated, a force which can be felt by the operator, which increases from the start of the rotation and only decreases again when the switching star reaches its next end position.
  • the operator therefore feels a rising and then decreasing force each time a switching star is rotated from one end position to the next end position, which reliably prevents the operator from leaving switching stars in an intermediate position. Since only one spring tongue is assigned to each switching star, the inhibiting device formed by the spring tongues can also be produced with inexpensive means.
  • the ribbon printing unit shown in FIG. 1 contains four type ribbons 1, 2, 3 and 4, which are provided with printing types 5 on their outer surface.
  • the type tapes are endless tapes which are guided around an adjusting wheel 6 and around a switching star 8 which can be rotated about an axis 7.
  • Each type band carries twelve print types 5 on its outer surface; in the illustrated embodiment, these types of printing can Numbers 0 through 9, a period and a dash are printed.
  • this adjustment mechanism contains a rotary knob 10, which is non-rotatably seated on a hollow shaft 11.
  • This hollow shaft 11 is rotatable in a side wall 12 of the ribbon printing unit and is displaceable in its longitudinal direction.
  • an axis 14 is fixedly connected to the other side wall 13, which projects into the interior of the hollow shaft 11 and guides it when it is displaced in its longitudinal direction.
  • the end of the hollow shaft 11 lying between the two side walls 12 and 13 carries a pinion 15 which can be seen in FIG. 2 and which can be brought into line with one of the adjusting wheels 6 by axially displacing the hollow shaft 11.
  • the setting wheels 6 are mounted without fixed points on a support body 18 which is fixedly connected to the side walls 12 and 13.
  • the pinion 15 is aligned with the adjusting wheel 6 assigned to the type tape I.
  • the pinion is aligned with the setting wheel 6 of the type tape 4.
  • the hollow shaft 11 is in an intermediate position in which the pinion 15 is in line with the setting wheel 6 of the type tape 3, so that by turning the knob 10 this setting wheel 6 and thus the type wheel 3 driven by it are displaced can.
  • a display device 19 which is fixedly connected to the hollow shaft 11 and has a pointer 20 which is in line with the pinion 15 and which in each case comes to lie exactly above the type band which can be moved by turning the rotary knob 10.
  • a window 21 is provided in the display device 19, through which the type band, which is just adjustable, can be viewed. So that it is precisely recognized which print type is in the position of the print types 9, not only the twelve previously mentioned print types but also a corresponding number of fields 21a are attached to the outer surfaces of the type bands, each of which is printed with a character corresponding to a print type . These imprints are applied in such a sequence that the window 21 of the display device 19 can be used to precisely identify the character that can be printed with the print type in the position of the print type 9.
  • projections 22 are attached to the inner surface of each type band, which are mounted in corresponding grooves 23 on the outer peripheral surface of each setting wheel.
  • the switching stars 8 also have a corresponding groove 24 in each of their four straight peripheral surface parts, into which the projections 22 of the type strips can engage.
  • the rotary knob 10 If, in order to set a specific number to be printed, the rotary knob 10 is rotated in the position of the hollow shaft 11 shown in FIG. 1, the pinion 15 drives the setting wheel 6, so that it takes the associated type band 3 with it. Due to the engagement between the grooves 24 on the switching star 8 and the grooves 22 on the type strip 3, the switching star 8 also rotates about the axis 7.
  • the printing types 5 successively come into the position of the printing type 9, which the printing type is used for Must achieve the desired impression.
  • the print type for the number 6 is in the position of the print type 9, so that after a corresponding coloring with printing ink from the type tape 3, the number 6 is printed.
  • the number 8 is printed by means of the type tape 4. To simplify the illustration, the types to be printed have not been specified on type bands 1 and 2.
  • the print types 5 that are in the position of print type 9 must have exactly the same position on all type tapes after the setting process has been carried out using the rotary knob 10 occupy and lie exactly horizontally in the representation of FIG. 2. This position is only achieved if, after the setting process of the switching star 8 has ended, it assumes the position shown in FIG. 2, in which its peripheral surface part facing away from the setting wheel 6 lies horizontally in the view of FIG. 2.
  • an inhibiting device 25 which on the one hand prevents the switch stars 8 from freely rotating about the axis 7 and on the other hand ensures that the switch stars 8 are held in a locking position after each rotation by 90 °.
  • the inhibiting device 25 has a spring tongue 26 for each switching star 8, which is held non-positively in contact with the peripheral surface part of the switching star 8 which is directed towards the setting wheel 6 and lies between two switching star corners.
  • the spring tongues are integrally connected to a base part 27 which sits in a groove 28 in the carrier body 18.
  • the extension planes of the suspensions 26 are each inclined at an angle a with respect to the plane of rotation about which the switching stars 8 rotate about the axis 7 can.
  • the plane of extension is rotated relative to the plane of rotation about a straight line common to the planes, which is perpendicular to the image plane of FIG. 3.
  • the spring tongues 26 resiliently resting on the adjacent peripheral surface parts of the switching starters 8, preferably at an angle of 75 to 77 °, hold them firmly in the position of FIG. 2, however, due to their spring properties, they can yield so far that a switching star 8 under the Action of a driven type belt can be rotated.
  • a spring tongue 26a bends more strongly when the associated star wheel 8 is rotated by the type tape.
  • the spring tongues 26 thus oppose the rotation of the switching star 8 different forces, depending on whether the spring tongue rests on a peripheral surface part of the switching star, or whether it is bent more by a corner of the switching star.
  • the force peaks occurring when a switching star corner acts on a spring tongue 26 are clearly perceptible, so that they know that each time a force peak has been overcome, the straight line Moving switching star assumes a defined position in which a printing type 5 is exactly in the printing position of the printing types 9.
  • the force exerted by the spring tongues 26 on the switching star 8 is sufficient to turn the respective switching star 8 exactly into the position shown in FIG. 2 if the operator has already finished turning the rotary knob 10 before the switching star 8 reaches this position Has.
  • the edges of the spring tongues 26 which are in contact with the switching stars are provided with an arcuate cutout 29 which runs parallel to the arc which the corner of a switching star 8 describes during its rotational movement. In this way, excessive bending of the spring tongues 26 when turning the switching star 8 is avoided.
  • the spring tongues 26 can be produced together with the base part 27 as a single component made of thermoplastic using the injection molding process.
  • the insertion of the inhibiting device 25 into the carrier body 18 requires only a single operation, which has a favorable effect on the assembly time of the entire ribbon printing unit.
  • the inhibiting device 25 used to achieve this result can be manufactured inexpensively on the basis of its construction and can be installed in the ribbon printing unit.
