Definitions

  • the present invention relates to a print ribbon cartridge arrangement for a printing machine, in particular for thermal transfer printing, comprising a cartridge body having: a ribbon inlet and outlet located on or in the immediate vicinity of a first side of the cartridge body; two axes for winding and unwinding the ribbon; and guide means for guiding the moving tape.
  • the mobile carriage In certain types of printing machines, and in particular in certain fast printing machines, such as for example (but not exclusively) in certain thermal transfer printing machines, it is desirable to lighten the mobile carriage as much as possible, comprising inter alia the printing means, so as to reduce the inertia and increase its speed of movement while retaining all the precision required in its positioning with respect to the printing medium.
  • the printing ribbon cartridge which is traditionally mounted on the carriage, be separated from the latter: it is then necessary for this cartridge to be mounted fixed on the machine, the carriage, and in particular the printing means, then scrolling, for the printing of each line, not only in front of the printing medium, but also in front of the ribbon.
  • Such an arrangement therefore implies that, during each printing sequence, there is presented in front of the printing medium a length of ribbon at least equal to the maximum length of the line to be printed, that is to say at least equal to the width of the print media.
  • the object of the invention is essentially to design a print ribbon cartridge which has dimensions of the same order of magnitude as conventional cartridges during their storage and arranged to, during their use, release a sufficient length of ribbon to cover a printing line, while being simple in structure and therefore relatively inexpensive, and while being arranged to possibly contain a very thin ribbon (for example of a thickness less than 12 ⁇ m) used for printing by thermal transfer .
  • a cartridge of the kind mentioned in the preamble is characterized in that it further comprises two arms situated on either side of the cartridge body and supported respectively on the two opposite sides substantially transverse to the aforesaid first side, each arm having a first end provided with sliding and pivoting connection means with the corresponding side of the cartridge body so that the arm can, from a first non-functional position (or storage position of the cartridge) in which the arm extends along the side of the cartridge body with said first end located in the vicinity of the side of the cartridge opposite the aforesaid first side and with its free end -fitted with guide means over which passes the tape - located in the vicinity of the aforesaid first side, pass, by an axial sliding followed by a rotation, to a second functional position (or position of use of the cartridge) in which the arm extends substantially in the extension of the aforesaid first side with its first end located in the vicinity of said first side, and in that it further comprises elastic means tension ticks
  • a cartridge which, with its arms folded, has general dimensions substantially identical to those of a standard cartridge embeddable on the mobile printing system, but which, with its arms extended, extends substantially over at least the entire width of the print medium and exposes a length of ribbon at least equal to the width of this print medium.
  • the connecting means provided at the first end of each arm comprise at least one guide finger capable of sliding in a gutter provided along the corresponding side of the cartridge body, blocking means preventing rotation of the arm as long as the finger is not located at the end of said gutter close to the first side of the cartridge body: a cartridge structure is thus produced which is particularly simple to manufacture, to assemble and to use, with a small number of parts constitutive.
  • each arm may also be advantageous for each arm to have a U-shaped or tubular cross-section to house and protect the portion of tape which passes through it.
  • the means for guiding the ribbon comprise Crazy rollers rolled into a barrel shape which automatically return the ribbon to its correct alignment position.
  • synchronization means comprise a idler wheel supported at one end of an arm resiliently biased so that the idler wheel is constantly held in elastic support simultaneously on the two reels of ribbon of the winding and unwinding axes.
  • the ribbon cartridge according to the invention comprises a housing 1, in the form of a flattened parallelepiped whose general dimensions correspond substantially to those of a usual cartridge intended to be loaded on the mobile carriage of the printing machine.
  • the two main faces 2 of this box support the two axes 3 of the coils on which the ribbon 4 is wound.
  • Two opposite sides A of the housing 1 are respectively equipped with two arms 5 movable in translation parallel to the sides A of the housing and in rotation.
  • Each arm 5 consists of a U-shaped piece overlapping the corresponding side A of the housing 1, as more clearly visible in FIG. 4.
  • the two branches facing the U respectively carry two projecting fingers 6, directed one towards the 'other, engaged in two respective gutters 7 dug in the main faces 2 of the housing parallel to the side A thereof.
  • the main faces 2, in the vicinity of their extreme edges bordering the sides A considered, have a thinning delimiting the shoulders 8 parallel to the gutters 7 and against which the longitudinal edges of the arms of the U-shaped arms can bear.
  • the arms 5 can only slide parallel to the sides A of the housing 1, without being able to rotate. Once the arms 5 have reached maximum extension (stops (not visible) provided at the end of the gutters 7 prevent the fingers 6 from leaving the latter), these arms are free to pivot 90 ° outwards, moving away of the housing 1, to extend approximately in the extension of one of the long sides B of the housing 1, as shown in FIG. 3.
  • the ends 5a of the arms 5 are inclined so that, in the functional printing position shown in FIG. 3, the exposed part of the ribbon 4 is moved away from the edge of the case 1.
  • rollers 91 at the free ends of the arms 5 rollers 92 at the elbows of the arms 5; rollers 93 at the ends of the arms 5 carrying the aforementioned fingers 6; rollers 94 in the vicinity of the coils 10 on which the ribbon is wound.
  • means 11 for keeping the ribbon under tension comprise rollers 9 sur mounted on springs 12; the rollers 95 are thus free to oscillate between two extreme positions as a function of the force exerted by the ribbon and maintain the latter with a substantially constant tension.
  • the reel 10 on the left is receiving (driving) and the roller 95 on the left is fully pushed in at the end-of-travel stop, while the reel 10 on the right being supplying, the roller 95 on the left oscillates around a position d balance which ensures the constant tension of the ribbon.
  • openings 13 are provided, for the passage of the tape 4, in the sides A of the housing 1, in the vicinity of their junction with the side B.
  • the ribbon 4 has been shown in solid lines for its visible part and in dashes for its hidden part.
  • the tape 4 travels permanently away from external damage and is only accessible between the rollers 91 of the free ends of the arms 5.
  • the length of the arms 5 -and therefore the length of the sides A of the cartridge- is determined so that the length of the accessible part of the ribbon 4 (slightly less than the distance between the rollers 91) is at least equal to the maximum length of a printing line on the printing medium (that is to say substantially the width of a sheet of paper for example).
  • the thickness of these ribbons is very small (for example less than 12 ⁇ m).
  • Such ribbons therefore do not have the transverse resistance necessary to be able to be properly guided. by the traditional grooved pebbles.
  • a disc 14 provided with a locating means for a detection member 15, connected to a signal processing circuit (not shown) making it possible to detect the rotation of the disc 14 and therefore manage the running of the ribbon, when positioning a new section of blank ribbon between the printing processes of two successive lines.
  • the disc 14 may include a marker and the detection member 14 may be an optoelectronic transmitter-receiver member associated with a pulse counting circuit.
  • an untimely unwinding of the ribbon with the risk of jamming - means are provided for synchronization of the rotation of the two coils 10.
  • These means comprise a idler wheel 16 mounted at the free end of a free arm 17, the other end of which is mounted to rotate freely on elastic return means.
  • These can advantageously be constituted by a spring leaf 18, one end of which is anchored in the housing 1 and the other end of which rotatably supports the arm 17, the spring 18 ensuring the permanent support of the wheel 16 simultaneously on the two ribbon windings of the two reels 10 respectively.
  • the ribbon cartridge which has just been described is arranged symmetrically. It is thus possible for it to assume a symmetrical operation with scrolling of the ribbon from left to right or from right to left, the two coils being respectively driven selectively.
  • the structure of the cartridge allows in particular the inversion thereof and the use of two separate longitudinal areas of the ribbon, which makes it possible to double the capacity for using the ribbon.
