Definitions

  • the invention relates to an inking unit for inking the value-stamp rotor of a franking machine, with a storage container for receiving liquid stamp ink and with at least one absorbent roller as an intermediate carrier of the ink, one of which is constantly in rolling contact with the value-stamp rotor.
  • Stamp machines are known in which the liquid stamp ink is contained in a storage container which is open at the top.
  • the ink is removed from the container by a roller, which partially dips into the ink supply from above and thereby absorbs ink.
  • the roller is in indirect rolling contact with the rotating stamp of the machine via several absorbent rollers.
  • the absorbent rollers serve as temporary storage for the stamp ink and, if necessary, deliver more or less ink to the stamp.
  • the arrangement is simple, but does not allow precise metering of the color given per stamp impression, which results in unevenly colored prints, which is undesirable.
  • Another inking device for a stamping machine is known from the Swiss patent specification 393 375.
  • This inking device uses a color cartridge which has an inner, hollow cylinder provided with openings, which is provided on the outside with a porous coating. This coating soaks up the ink contained in the interior of the ink cartridge and, if necessary, transfers it to the value-stamp rotor via a weakly absorbent intermediate or inking roller.
  • the arrangement works satisfactorily, but requires a very precise matching of the properties of the color and the porous coating of the color cartridge.
  • such color cartridges are relatively expensive and. require visual monitoring of their degree of color filling.
  • the object of the invention is to provide an inking unit for a value stamp or franking machine which is not critical with regard to the properties of the stamp color and the absorbent rollers and which enables a good dosage of the ink to be dispensed per stamp impression, regardless of the degree of use and the downtimes of the machine .
  • This object is achieved by an inking unit as defined in claim 1.
  • the further claims specify configurations of the inking unit defined in this way.
  • Fig. 2 longitudinal section through a double-sided, hollow, absorbent roller
  • Fig. 3 longitudinal section through a single-sided, hollow, absorbent roller.
  • FIG. 1 shows a schematic compilation of an inking unit for a stamp machine, for example a franking machine.
  • 11 denotes the value stamp rotor, on the cylinder surface of which an adjustable value stamp and optionally a date and / or an advertisement stamp are attached.
  • 12 is the axis of the rotor 11.
  • the rotor makes one complete revolution for each stamp impression.
  • an inking or intermediate roller 13 made of weakly absorbent material, which the stamp at Rotates the rotor 11 in a known manner.
  • the paint comes from a highly absorbent outer area (15) of a hollow supply roller 14, in which outer area a certain ink supply is always stored and which releases the ink to the inking roller 13 in a known manner when the supply roller 14 is rotated.
  • the hollow supply roller 14 is fed at intervals to be mentioned via a dye supply line, for example a hose 17, drop by drop into its interior stamping ink.
  • the supply 19 of the stamping ink is contained in a storage container 18 and is metered into the hose 17 by means of a piston pump 20.
  • the pump piston 23 carries out a linear reciprocating movement, which is forced by a linkage 26 coupled to the piston.
  • the necessary valves are indicated by the characters X and are designed, for example, as non-return ball valves.
  • the linkage 26 is guided by two guides 27 and 28. It is also movably coupled to the end 29 of a drive lever 31.
  • This drive lever 31 is rotatably mounted about an axis 32 and slides with one Nose 33 on an eccentric disk 34.
  • This eccentric disk 34 rotates together with a ratchet wheel 37, with which it is rigidly connected, about an axis 35.
  • a ratchet 38 is in engagement with the ratchet wheel 37, which is rotatably mounted about an axis 39 and is constantly held in engagement with the teeth of the ratchet wheel 37 by a spring 40.
  • the axis 39 and the pawl 38 are in turn mounted on a lever 45 which is rotatably mounted about the axis 35.
  • This lever 45 slides with a nose 46 on a second eccentric disk 47 which is fastened on the axis 12 of the rotor 11.
  • 49 is a spring that presses the lever 45 against the eccentric disk 47.
  • 50 is another spring which presses the linkage 26 upwards and at the same time presses the drive lever 31 against the first eccentric disk 34.
  • a pawl which is rotatably mounted about the axis 32 and which is kept in constant engagement with the teeth of the ratchet wheel 37 by a further spring 56.
  • the arrangement forms a ratchet and cam mechanism which is driven by the drive of the rotor 11. So moves with each revolution of the rotor 11th " the eccentric disc 47 the lever 46 back and forth once and the pawl 38 the ratchet wheel 37 by one tooth. During a number of rotor rotations given by the number of teeth of the ratchet wheel 37, it is controlled by the eccentric disc 34 coupled to the ratchet wheel 37," the linkage 26 and thus the pump piston 23 are moved up and down once, the amount of ink conveyed in this way is proportional to the number of revolutions of the rotor 11 or the number of value stamp impressions.
  • the stroke of the piston 23 can be regulated by a stop to which, for example, a more or less pushed-in wedge 60 (shown in section in FIG. 1) is assigned.
  • This combination means that the nose 33 of the drive lever 31 is not constantly on the adjustable. Eccentric disc 34 abuts and thus the maximum possible stroke is only used variably up to the desired percentage.
  • a corresponding electromechanical metering device is formed from a Electromagnetically operated pump, which is briefly switched on by an electrical counter when a preselectable number is reached.
  • the counter itself is incremented with each revolution of the rotor 11, for example by the trigger signal for the rotor drive. This ensures that the color is distributed in proportion to the number of value stamp impressions. The color can be varied by changing the number that can be set on the counter.
  • FIG. 2 shows a longitudinal section through a first embodiment of the hollow supply roller 14.
  • 15 is the absorbent outer region, which surrounds a load-bearing cylinder 65 in a cylindrical shape.
  • This cylinder 65 is designed, for example, as a plastic injection-molded part and has continuous openings 67 on its cylinder surface 66 through which the stamping ink can pass from the inside or the cavity 16 of the roller 14 into its outer region 15. These openings 67 are arranged in such a way that the outer region 15 is uniformly impregnated.
  • One end face 69 of the cylinder 65 is closed and shaped into a bearing journal 70 which is rotatably mounted in a bearing 71.
  • the other end face 75 of the cylinder 65 is open.
  • a tubular insert 77 is pressed into this opening, in which a second bearing journal 80 is in turn rotatably mounted.
  • This bearing pin 80 is rigidly connected to a linkage 81 which, together with the bearing 71, forms the holder for the supply roller 14.
  • the second bearing pin 80 further has a circular sealing lip 82 which resiliently on the inner wall of the Insert 77 abuts and seals the cavity 16 against the outside.
  • the bearing pin 80 finally has a central bore 85 which ends in a connection pin 86 to the outside and inwardly ends in a tube 87 which ends approximately in the center of the supply roller 14.
  • the paint supply line or the hose 17 (FIG. 1) can be connected to the connecting pin 86.
  • the supply roller 14 thus described has an essentially cylindrical cavity 16, which has direct contact with the absorbent outer region 15 of the roller via the openings 67.
  • the cavity 16 is essentially sealed to the outside.
  • FIG 3 shows a further embodiment of a storage roller 14.
  • This roller is mounted on one side in a bearing 91 via an axle pin 90.
  • the cavity 16 is enclosed by a load-bearing cylinder 92, in the cylindrical surface of which through openings 93 establish a direct connection between the cavity 16 and the absorbent outer region 15.
  • the end face 95 assigned to the journal 90 is closed, while the other end face 96 is at least open in its central region. Through this The opening extends the paint supply line or the hose 17 approximately into the center of the cavity 16. It is optionally possible to seal the opening against the paint supply line 17 by means of a lip seal 98.
  • the supporting cylinders can be dispensed with and the cavity 16 is in direct contact with the outer region 15 over its entire cylinder surface.
  • the advantage of the inking units described is that, regardless of the degree of use of the franking machine and regardless of the length of the downtimes, an essentially uniformly colored colored stamp is always produced. On the one hand, this results from the controlled ink supply, which is proportional to the number of stamps. Secondly, it results from the use of a hollow roller 14, through which the ink supplied in portions inside is distributed from the inside to the outside and is evenly dispensed.
  • the inking units are not critical in use. The stamping ink required as consumable material can simply be kept in stock and refilled into the storage container 18 if necessary. Furthermore, the properties of the paint and the absorbent outer region 15 of the supply roller 14 are relatively uncritical and only require mutual coordination that is easy to produce.

Abstract

Le dispositif d'encrage comporte une pompe (20, 23) prélevant de manière dosée l'encre d'un réservoir (18). L'encre (19) est amenée par un conduit (17) à l'intérieur (16) d'un tambour creux (14). Ce tambour (14) présente une périphérie absorbante (15) qui absorbe l'encre (19) à l'intérieur et l'amène, à l'aide du rouleau encreur (13), au timbre situé sur le rotor (11) de la machine, pour son encrage. L'actionnement de la pompe (20, 23) est obtenu à l'aide d'une tringle (26), soumise à l'action d'un ressort et mobile linéairement en va-et-vient, qui est accouplée mécaniquement à l'axe (12) du rotor (11), par un levier de commande (31), un mécanisme à cliquet (37, 38, 45) et des disques à came (34, 47), de manière qu'à chaque rotation du rotor (11) la roue à cliquet (37) avance d'une dent. Une course complète du piston de la pompe (23) correspond ainsi à un nombre de tours du rotor égal au nombre de dents de la roue (37). Le dosage de l'encre se fait ainsi proportionnellement au nombre des impressions et donc à l'utilisation.
