Definitions

  • the invention relates generally to a device for re-inking ribbons, in particular those used in typewriters or printers, and more particularly ribbons in cassette.
  • the invention intends to largely remedy these drawbacks by proposing a device for re-inking ribbons, in particular ribbons for typewriters or printers, which is simple to use and can be applied to most types of ribbons inked in cassettes, whatever the type.
  • the first object of the invention is such a device for re-inking ribbons.
  • a preferred dispenser according to the invention is provided with at least one fluid dispensing opening or with a fluid ejector respectively having cross-sections allowing the deposition of the fluid only over part of the width of the strip running past it.
  • the member with which the distributor or the cartridge is secured is itself rotary, the second plate itself being provided with means causing the distributor or the cartridge to rotate. .
  • the invention also relates more particularly to cartridges comprising an enclosure for a fluid and dispensers of fluid, in particular ink, advantageously used in combination with the device described above, therefore capable of being mounted on one of the plates of the device according to the invention.
  • the cartridge according to the invention comprises appropriate means allowing access to the outside of the fluid contained in said cartridge, as well as means allowing a sealed closure of the cartridge.
  • the means which constitute the two separate openings and which allow access towards the outside of the fluid contained in the cartridge are located near one of the ends of the cartridge, in particular in the lower part of the cartridge when the latter is placed on the second plate.
  • the two separate openings are located in the same plane perpendicular to the axis of the enclosure. It goes without saying, however, that these two openings may lie in another plane, in particular a plane parallel to the axis of the enclosure.
  • the separate member is constituted by a cap mounted frictionally or sliding on the enclosure from the other end thereof, so as to allow relative movements thereof vis-à-vis the enclosure, between a respective first relative position and a respective second relative position.
  • one of the two elements which constitutes the enclosure or the cap has two separate openings and the other of the two elements has a slot.
  • the enclosure and the cap are cylindrical, coaxial and engaged in friction with one another, the passage from the first to the second relative position, it is vice- conversely, being obtained by rotation of one of the two elements with respect to the other about their common axis.
  • this protruding part has a dimension smaller than the length of the slot and slides therein. Under the action of said elastic means, the projecting part of the shutter member projects outwards from the cartridge. In this first position, the protruding part seals the greater part of the slot formed on the wall of the enclosure and the fluid contained in said enclosure does not have access to the outside.
  • the projecting part of the shutter member can retract into the enclosure under the effect of a thrust exerted from the outside and directed towards the inside of the enclosure . In this position, the projecting part no longer completely closes the slot provided on the wall of the enclosure and thus releases on its two sides, two openings at the two opposite ends of the slot.
  • the fluid contained in the enclosure can then have access to the outside and be deposited on the strip running past one of these openings, the other opening then not being covered.
  • the removable closure member is constituted by a roller capable of rotation along its own axis, preferably toothed or with a rough surface, having an overall diameter greater than the length of said slot, l 'axis of this caster mounted inside the enclosure being subject to the action of the above elastic means to exit at least partially out of the cartridge through the slot, this axis can be moved inwardly under the action of an external thrust against the action of elastic means.
  • the caster can only partially exit the enclosure through the slot, the overall diameter of said caster being greater than the length of the slot.
  • the axis of the caster is part of the elastic means, more particularly of a spring wedged inside the enclosure and tending to exert a force directed towards the outside of the enclosure so as to partially exit a part of the caster through the slot to the outside of the enclosure.
  • the roller capable of rotation along its own axis has teeth or is provided with a rough surface, for example based on felt.
  • the external thrust is then exerted by the ribbon brought into contact with the caster, near one of the ends of the slot.
  • the scrolling of the ribbon then drives the roulette in rotation.
  • the teeth of the caster or the rough surface of the latter contribute to the ejection, out of the enclosure, and, when the caster is subjected to rotation, to the deposition of the fluid, in particular contained between two teeth or on the rough surface, on the part of the tape coming into contact.
  • the enclosure is cylindrical
  • the separate member closes the enclosure at its other end is a coaxial cylindrical cap mounted sliding on the enclosure, this cap itself being provided of a slot.
  • the slot in the cap coincides with that of the enclosure, the removable closure member then protruding partially out of the enclosure through the two overlapping slots.
  • the ribbon contained in its cassette has been shown, represented by phantom lines, coming to rest against one of the sides of the caster, and driving it in rotation when it is itself brought to scroll past one end of the slit.
  • the re-inking device of the invention comprises a plate (1) on which is disposed a first rotary plate (3).
  • the first plate (3) has a first eccentric axial member (5), allowing the installation of a cassette, in this case a hollow cylindrical guide (5) passing through the plate.
  • This hollow cylinder allows the establishment of two complementary elements (5a) and (5b) capable of engaging one another and one of which (5a) is capable of being driven in rotation by the motor. (9), in particular by means of a worm (7), and the other (5b) is capable of engaging with the axis of the cassette or an axis of drive of the ribbon housed at the inside the cassette.
  • the tray also has on its peripheral surface a housing (11) which can receive several other elements (5b), represented by (13), which can be accommodated in the eccentric hollow guide (5) and the upper parts of which adapt to different types of existing cassettes.
  • the plate (3) also includes a particular device (15) which can be housed in the hollow guide (5), and usable with cassettes having no internal axis for driving the ribbon.
  • the device (15) is provided with two rotary elements (17) rotating in opposite directions and between which the ribbon can be inserted.
  • a tab (19) is provided to separate the elements (17) from one another, in order to allow the release of the ribbon between the two elements (17).
  • the plate (1) further comprises a second plate (21) rotatable about its axis, placed near the first plate (3) and on which is mounted a second eccentric member (25) allowing the installation of a distributor fluid (27).
  • a cavity (31) is provided on the peripheral surface of the plate (21), for the finger of the user who can thus rotate the plate (21) manually around its axis.
  • a control panel (33) and a reserve (35) for storing several distributors (27) are also mounted on the plate (1).
  • the eccentric member (5) carried by the first plate (3), interacts with two parts (5a), (5b) one of which (5a) is connected to the drive system (7) of the motor. (9) and the other (5b) of which is provided with a male section which engages with the female section of the drive axis of the cassette, when the latter comprises one.
  • the plate (1) also comprises below the second plate (21) a system of collars (22) and secondary plates (24, 26) which can rotate around their common axis and which makes it possible to vary the height of the second plate ( 21) relative to the first plate (3), so that the distributor (27) placed on the second plate (21) can be brought to heights different from the first plate (3) and the ribbon placed on this plate (3).
  • FIGs 4 and 5 shows the device of the invention in use, with two different types of cassettes.
  • a cassette (37) containing a ribbon (39) is placed on the first plate (3).
  • the cassette (47) has a drive mechanism (38) specific to itself and allowing the complete travel of the tape outside the cassette, in a determined zone (41) located between two tabs (43).
  • the eccentric member (5) drives the drive mechanism (38) of the cassette and the ribbon (35) runs between the two arms (43) of the cassette.
  • the part (45) of the ribbon (39) then receives a uniform longitudinal strip of the fluid contained in the distributor (27).
  • a cassette (37) is placed on the first plate (3).
  • Cassette (37) has no mechanism clean drive allowing the tape (39) to run.
  • the device (15) mounted on the eccentric member (5) (not shown) is used.
  • the ribbon (39) is inserted between the two rollers (17).
  • the second plate (21) is rotated so as to make contact between a part (45) of the ribbon (39) and the dispenser (27) in a determined region (41) external to the cassette (37).
  • the device (15) integral with the motor (9) then allows the tape (39) to run in contact in its part (45) with the distributor (27) and a longitudinal strip of fluid can be applied to the tape (39).
  • the contacting of the ribbon and the dispenser is generally obtained by subjecting the second plate (21) to a rotation along its own axis.
  • the cartridge comprises an enclosure (47) closed at its upper end, and provided on its side wall and near its lower end with two openings (49).
  • the wall of the cap (51) is further provided with a slot (55) near the base of said cap.
  • the enclosure (47) is mounted on the cap (51) by friction, the two elements being able to rotate relative to each other about their common axis.
  • the fluid contained in the enclosure (47) can exit through the slot (55) and the two holes (49).
  • the ribbon comes into contact with the cartridge at only one of the two holes (49), the other having to remain uncovered.
  • the cartridge comprises a cylindrical enclosure (47) closed at its upper end and provided on its side wall with a slot (48) near its lower end.
  • the cartridge further comprises a separate member (51) constituting a cap, mounted frictionally and sliding on the enclosure, and closing it at its lower end.
  • the cap (51) has on its side wall a slot (55) near its lower end.
  • a toothed roller (57) is housed inside the cap (51), at the level of the slot (55).
  • the caster (57) is retained by means of a spring (59) which on the one hand tends to push the caster (57) outwards through the slot (48) on the one hand and on the other hand , through the slot (55), when the two slots are mutually superimposed.
  • the cartridge When the two slots (48, 55) are superimposed, and the caster (57) partially comes out of the cap, the cartridge nevertheless remains practically closed provided that the caster (57) is not subjected to rotation. Indeed, the outward projecting parts of the caster come close to the ends of the superimposed slots (48, 55), so that the latter are practically closed, at least regard to the viscosity of the fluid which is sufficient to prevent it from coming out of the cartridge.
  • the caster (57) In the first relative position of the cap (51) with respect to the enclosure (47) in which the two slots (48, 55) are superimposed, the caster (57) partially exits the cartridge through the slots (48, 55) under the action of the spring.
  • the roller (57) then reveals two separate openings (61, 63) at each of the corresponding ends of the superimposed slots (48, 55).
  • the ribbon passes in contact with one of these two separate openings (61, 63), it drives the wheel in rotation. This then contributes to the extraction of the fluid to be deposited on the tape out of the enclosure in the form of a uniform strip, while the other opening allows the entry of air inside the cartridge. .
  • the arrow (c) indicates the direction of travel of the ribbon in relation to the cartridge.
  • the cartridge When not in use, the cartridge is easily sealed by subjecting one of the two enclosure or cartridge elements to rotation, so that the slots respectively carried on the walls of these elements no longer overlap.
  • the caster When the enclosure closing member is not formed by a sliding cap on the lower part of the enclosure, the caster can be pushed inward by an adhesive strip (65) at the slots ( 48, 55), in particular if the cartridge is not used, as shown in FIG. 8a.
  • cartridge of the invention for depositing a strip of glue on a surface capable of receiving it, in particular a sheet of paper or an envelope, or the deposition of a colored liquid on a surface.
