Definitions

  • ABSTRACT A printer including a printing plate. a dating device having a detachable unit which is detachably connected to the printing plate. and a movable hammer for applying a force to the dating device.
  • the dating device has an axle of polygonal cross-section, type wheels including a rim of elastically deformable material with a polygonal inner-section movably mounted on the axle and connected to the printing plate to be movable in the direction of movement of the hammer. and types on the type wheels.
  • the types on the type wheels opposite those types which are in the printing position are located at a distance from the printing plate.
  • the present invention relates to a dating device for a printer with a printing plate and a printing hammer, e.g., for cash-registers, scales with tag printers for retail or packaging chains, as well as for other apparatuses with similar printing tasks, in which, besides an optional text like company or product name, at every printing process various data like price and/or weight,
  • the date of sale or the last allowed date of sale of a product is generally adjusted by means of type wheels rotating on one or" several axles fixed in' the apparatus.
  • the date is adjusted on or in the apparatus itself, either by directly adjusting the type wheels by means of a suitable instrument or by turning adjusting disks connected with the type wheels for example by means of concentric tubular shafts.
  • the number of type wheels thus being operated is limited by the strength of the material employed for the tubular shafts. Furthermore, the choice of the position or the location 'of the date on the printed tag is limited by the other mechanical characteristics of the printer, because generally such a construction with tubular shafts is chosen in order to have free access to the adjustment disk. If the construction, because of the mechanical design of the apparatus or the small dimensions of the digits tovbe printed, does not provide tubular shafts, the adjustment of the date has to be made directly with a suitable instrument. This implies free access to the type wheels, which fact influences the construction of the printer itself.
  • the dating device is designed as a detachable unit.
  • This unit is preferably provided with type wheels movably assembled in the direction of motion of the printing hammer.
  • the dating device is provided with at least one fixed polygonal axle on which elastically deformable type wheels with a polygonal inner section are assembled, the characters opposite to those adjustsed for printing being at a distance from the printing plate and touching it only during the printing process.
  • it can be provided with two parallel polygonal axles disposed one upon the other, each one carrying a series of type wheels. If the dating device is used on a printer with a printing block placed on its printing plate, the surface of the characters adjusted for printing conveniently projects over the surface of the printing block in the direction of the hammer.
  • the type wheels may present digits and'other symbols.
  • FIG. 1 shows a schematical view of the dating device, with partial section, and
  • FIG. 2 shows, in a larger scale, a cross section of the dating device assembled on a printer.
  • the dating device shown in FIG. 1 comprises a frame 5 consisting of two side plates 1, 2, cross bars 3 and a handle 4. Two two-edged axles 6 are mounted in this frame 5. Their ends are provided with projecting parts 7 which engage into corresponding slits of the side plates 1, 2. Four type wheels 8 are assembled on each of these axles 6. In the embodiment shown the upper series serves for printing the day and the month, the lower one for printing the year.
  • Each type wheel 8 is provided with ten characters 9, the digits from O to 9. Each character 9 is separated from the others by a groove 10. Each type wheel 8 has an internal and external decagonal section.
  • the dating device is mounted in the schematically represented printer.
  • the sole parts of the printer shown are the printing plate 12 with fixed printing block 13, the inking ribbon l4 and the printing hammer 15.
  • the dating device is retained by the bent edge 16 of the side plate 1, which engages in a groove 17 of the printing plate 12, as seen in FIG. 2, and by the cooperation of the two side plates 1 and 2 with the side walls of an aperture formed in the printing plate 12, the aperture being formed by the two side walls and a back plate 18 perpendicular to the two side walls.
  • the whole is constructed in such a manner that the suface of the types of the type wheels 8 being in printing position project a little over the surface of the printing block 13.
  • the surface of the opposite types does not touch the back plate 18 of the printing plate 12, but is at a distance from it.
  • the groove 17 has a sufficient width to allow the bent edge 16 and along with it the entire dating device to slide towards the back plate 18 to enable the types on type wheels 8 facing the back plate 18 to contact the plate 18 during the printing process.
  • the operating principle of the device described is the following: during the printing of the date the printing hammer 15 exercises, across the paper 19 and the inking ribbon 14 placed between the hammer itself and the dating device, a force on the latter, which deforms elastically the type wheels 8.
  • the two-edged axles 6 do not absorb considerable forces, because these forces are transmitted to the printing plate 12 over the types opposite to those in printing position.
  • the type wheels 8 are in contact with the support only when they have to transmit forces.
  • the dating device is withdrawn from the printer and the type wheels 8 are rotated e.g., by means of a pin engaging in the groove 10. By this they are also elastically deformed, because, as they are gliding over the edges of the axle 6, the distance of two opposite surfaces of the internal decagon is enlarged.
  • the device described has numerous advantages.
  • the dating device forms an independent unit which can be adjusted outside the printer and then inserted in it; if the requirements for the printer change, with subsequent changes in paper size or format of the adjusted date, another dating device may be used, without redesigning the printer.
  • the larger tolerances for the type wheels are advantageous: if the printing force is' absorbed by the axle or axles of the type wheels, both the type wheels and the axles have to be manufactured with very small tolerances, because the types are in contact with the support from the beginning. In the device described, the contact with the support is generated by the printing process itself, and the type wheels being elastic, relatively large tolerances for the diameters of the type wheels are admissible. For this reason it is easy to insert the dating device.
  • the embodiment has been represented as a dating device with type wheels which are provided with only ten digits. Practically the type wheels can be provided with more than ten characters. In some cases this is even necessary.
  • legal instructions which require, that in the case one number date or weight is not printed, a filler symbol, e.g., of an asterisk or a dash, is printed.
  • a filler symbol e.g., of an asterisk or a dash
  • the indication morning or afternoon should be made.
  • the letters am and pm can be used.
  • further type wheels with alphanumeric or graphic symbols might be used. Type wheels with the ten digits to 9 and other symbols could also be provided.
  • a printer comprising: a printing plate having a plurality of sides forming an aperture extending from a front face of said plate a predetermined distance into said plate to one of said sides which substantially parallel to said front face, and a groove extending along another of said sides; a dating device, detachably connected inside said aperture to said printing plate, including a frame having means which is slidably engaged in said groove to slide backward and forward between said front face and said one side, an axle connected to said frame having a polygonal cross-section with two opposite first edges, type wheels, of an elastically deformable material, each having a polygonal inner crosssection with a plurality of second edges spaced apart by a plurality of sides, said wheels being rotatably mounted on said axle and in which two of said second edges of said wheels rest on said two opposite first edges of said axle, the distance between said two opposite first edges being greater than the distance between any two opposite sides of said polygonal inner crosssection, wherein when said wheels are rotated on said axle said inner cross-section is deformed
  • a printer according to claim 1 further comprising a printing block connected to said front face of said printing plate, and wherein said types in the printing position project ahead of said printing block in the direction towards said hammer.
