Definitions

  • the invention relates to a consumable for a printing device, comprising two rollers carrying a printing ribbon which are supported by a support.
  • Consumables comprising two rollers carrying a printing ribbon which are marketed in a plastic packaging adapted to support the ends of the rollers so that the rollers are maintained in a position identical to a service position.
  • the package comprises a thermoformed plastic sheet to form a support for the ends of the rolls and a welded film to close the package.
  • the closing film is removed so as to release access to the rollers, then a cassette is provided on the thermoformed support having two cut side walls to present completed guideways. by receiving bearings of the ends of the rollers.
  • the cassette is presented facing the thermoformed support so that the guide tracks then extend vertically above the ends of the rollers.
  • the cassette is then pressed into the thermoformed support until the ends of the rollers are snapped into the receiving bearings of the cassette, and then the cassette (whose rollers are now secured) is removed from the thermoformed support to put it into place. in the printing device.
  • thermoformed support holding the rolls is not entirely satisfactory. Indeed, once the closing film removed, it is not possible to return the support without risk of falling the rollers. This provision obliges to present the cassette over the rollers, which is not the most natural movement for the user.
  • the invention relates to a consumable for printing device allowing easy placement of the rollers indifferently on a cassette or directly in the printing device.
  • the invention also relates to a receptacle particularly adapted to the release of the support during the introduction of the rollers in the receptacle.
  • a consumable for a printing device comprising two rollers carrying a printing ribbon and intended to be put in place directly in a receptacle of the printing device, the rollers having ends which are held by a removable support adapted to keep the rollers immobile between them in a position identical to a service position to facilitate the introduction of the rollers in the receptacle.
  • the support comprises a portion of U-folded sheet material for presenting two opposite side walls which comprise orifices in which the ends of the rollers are engaged.
  • the cardboard support positively maintains the rollers and forms a roller handling member which can be turned without risk of falling. rolls.
  • the rollers can thus be easily placed on a cassette by approaching the rollers over the cassette, which is more natural.
  • the rolls can also be put into place in a printing device, regardless of the orientation of the roll receiving area.
  • the thinness of the side walls of the sheet support allows the introduction of the support even in the case of a small clearance around the receiving area of the rollers.
  • the consumable of the invention therefore makes it possible to envisage the introduction of the rollers directly into the printing device.
  • the consumable 1 comprises a cardboard support 2 intended to carry rollers 7 carrying a printing ribbon 8 shown here in transparency to better reveal the support 2.
  • the support 2 comprises a base 3 and two lateral walls 4 opposite, which form a U-shaped structure preferably obtained by folding a blank of cardboard cut.
  • One of the side walls 4 has circular orifices 5, while the other side wall 4 has orifices having non-circular contours 6, here in the form of two half-moon cutouts.
  • the orifices 5, 6 are intended to receive the ends of the rollers 7.
  • each of the rollers 7 has a first circular end 9 inserted axially into one of the circular orifices 5.
  • Each of the rollers 7 has a second split end 10 terminated by two branches inserted axially into the half-moon blanks d. one of the non-circular orifices 5.
  • the cooperation of the slotted ends 10 with the non-circular orifices 5 makes it possible to immobilize the rollers 7 on the support 2 in rotation.
  • the rollers 7 are preferably arranged on the support 2 so that a free portion of printing ribbon 8 extending between the rollers 7 is stretched.
  • the support 2 forms a member for handling the rollers 7 which holds the rollers 7 immobile with respect to each other and which allows them to be put into place easily in a printing device receptacle, here a removable cassette 20.
  • the cassette 20 has a bottom wall 24 to which are attached side walls 21 cut away to have bearings 22 for receiving the ends of the rollers 7.
  • the bearings 22 extend at the end of parallel guideways 25 having inputs flared.
  • the support 2 is presented over the cassette 20 so that the ends of the rollers 7 are opposite the inputs of the guide tracks 25.
  • the support 2 is adapted to hold the rollers 7 in a position identical to a service position so that the rollers 7 are naturally opposite the inputs of the guideways 25.
  • the ends of the rollers 7 are then penetrated into the guideways 25, until the ends of the rollers 7 are placed in the bearings 22.
  • the bearings 22 are preceded by a slight restriction, so as to allow the ends of the rollers 7 to be latched when they are inserted into the bearings 22.
  • the base 3 of the support 2 has a length adapted to produce between the lateral walls 4 of the support 2 and the end face of the rollers 7 sufficient space for the passage of the lateral walls 21 of the cassette 20.
  • the support 2 is separated from the rollers 7.
  • the support 2 comprises a tongue 12 which is protrudes from an end edge 13 of one of the side walls 4. It is then sufficient to exert traction on the tongue 12 so as to straighten the side wall 4 and thus remove it from the ends 7. After this side wall is removed, it is easy to remove the other side wall.
  • FIG. 4 there is a cassette 20 equipped with rollers 7 freed of their support 2, ready to be inserted into a printing device 30.
  • the support 2 comprises a tongue 14 which this time extends from a lateral edge 15 of one of the lateral walls 4.
  • Pre-cuts 16 extend on this wall in order to detach the end portion 17 of the side wall 4 which carries the orifices 6, under the effect of a pull on the tongue 13.
  • Figure 6 illustrates a receptacle particularly adapted to an automatic release of the support during the introduction of the rollers in the receptacle of the printing device.
  • the receptacle is as before a removable cassette 20.
  • the side walls 21 of the cassette have on their outer face a ramp 23 which diverges outwardly from the introduction edge. 26 of the consumable.
  • the inner edges of the side walls 4 of the support 2 each bear on a ramp 23 so that the side walls 4 bend outwards.
  • the dimensions of the ramps 23 are determined so that the side walls 4 of the support 2 are released from the ends of the rollers when these ends reach the bearings 22 of the receptacle. This simplifies the structure of the support 2 by removing the tabs 12 or 14.
  • the support here comprises non-circular orifices having two half-moons adapted to receive the slit ends of the rollers
  • the support may comprise other types of non-circular orifices of contours homologous to the contours of the non-circular ends of the rollers (for example an end having a flat).
  • all the holes of the support may be circular. In this case it is possible to provide circular orifices with a diameter slightly smaller than the diameter of the ends of the rollers so as to stop the rollers in rotation by friction on the support.
  • the support here comprises a tongue on one of the walls
  • the support may include a tongue on each of the walls.
  • rollers have been illustrated with ends of the same diameter, it may be provided to provide one of the end rollers having a diameter greater than the diameter of the ends of the other roll, which allows, by giving the bearings and to guide the dimensions of dimensions adjusted to the corresponding ends, to organize a keying avoiding misplacement of the receiving roller in the bearings of the reel roller, and vice versa.
