Definitions

  • the present invention relates to franking machines, the print head of which is with a printing drum carrying printing rollers. It relates more particularly in such machines, to a device for locking in position the print wheels. (See for example US-A-4 160 899 or US-A-4 421 023.)
  • These printing wheels are, in known manner, rotatably mounted on the drum to allow them to be adjusted in position, in the absence of a franking operation. They are also slightly protruding on the periphery of the drum and rotatable with it, for printing fixed and variable postage information at each rotation of the drum.
  • the dials are used to print variable value and postage date information.
  • the printing drum therefore carries two sets of wheels for this variable information, which protrude from the drum through suitable openings in a plate engraved with postal stickers.
  • This engraved plate marries the periphery of the drum and carries the fixed postage information, in the form of imprints of the postage sticker and of the home office sticker, or another defined form.
  • This same drum generally carries, in addition, another engraved plate called advertising similar to the first but often retractable mounted, which is assigned to the printing of fixed advertising information.
  • other printing means such as one or more retractable pads are associated with the drum.
  • the knobs are generally coupled to a motorized or manual control assembly with so-called driving pinions driving, by a kinematic connection, so-called pinions driven on the knobs.
  • the motorized control unit is then connected to a control card itself connected to a data input means, for example a keyboard with display screen on the machine.
  • the object of the present invention is, once this adjustment has been made, to lock the racks and the printing knobs during their rotation with the drum at each printing cycle.
  • Locking devices currently exist and, by way of example of state of the art in the matter, can be cited the patent application FR-A-2,665,781 filed by the Applicant Company on August 7, 1990.
  • said unlocking finger is a centering finger of another member of the franking machine which is designed to cooperate with a guide opening which is made accordingly in the body of the printing drum.
  • the rotary printing drum 1 which normally equips the head of a franking machine.
  • the drum 1 is assumed to carry six coaxial printing wheels 2. When these wheels are not locked, it is possible to modify their setting, that is to say to modify the number or the letter which they print, by turning these knobs on themselves around their common axis 3.
  • knobs 2 are locked in position during the rotation of the printing drum, so that their setting cannot be modified, accidentally or not, during the printing operation of the values carried by these knobs. It is of course also necessary that they can be unlocked when the drum is in the rest position, and they can only be unlocked in this rest position.
  • the locking must be positive and therefore without risks. This would not be the case, for example, if it depended solely on a return spring that could accidentally break while the print drum was being rotated.
  • the device of the invention which will now be described and which equips the drum 1, makes it possible to satisfy these requirements.
  • This locking device basically comprises a locking stirrup 5 which is pivotally mounted around an axis 6 fixed on the drum 1 and parallel to the axis 3 of the knurls 2.
  • This tilting stirrup 5 has as many locking teeth 7 as there are knurls 2, ie five teeth 7 in the simplified example which is shown here. These teeth 7 are shaped and arranged to respectively engage in a tooth of the toothed wheel 4 associated with each wheel 2, thereby locking each of these wheels in position, when the stirrup 5 is tilted forward under the action of a powerful return spring 8 which is stretched between a stud 9 secured to the drum 1 and another stud 10 which is secured to an arm 11 of the stirrup 5, this stud 10 being placed on this arm 11, under the axis 6 so that the action of the spring 8 tends to cause the stirrup 5 to tilt forwards and therefore to engage the locking teeth 7 in the toothed wheels 4.
  • a powerful return spring 8 which is stretched between a stud 9 secured to the drum 1 and another stud 10 which is secured to an arm 11 of the stirrup 5, this stud 10 being placed on this arm 11, under the axis 6 so that the action of the spring 8 tends to cause the stirrup 5 to
  • a first free end 14 of this lever 12 comes to bear against a stop 15 integral with the stirrup 5.
  • the other free end 16 of the lever 12 has a lateral bulge 17 intended to cooperate with an external control finger 18 with a conical end 19. This finger passes through a guide orifice 20 formed in the body of the printing drum 1.
  • This arm 11 has, as shown, its free end 24 permanently engaged in a notch 25 of a locking safety pull tab 26 which is slidably mounted, by means of a slide 27 secured to the drum 1, on one of the generators of said drum 1 .
  • the tilting, shown in dotted lines, of the arm 11 can only be done by sliding, as indicated by the arrows, the pull tab 26 along said generatrix of the drum which is coaxial with it.
  • the free end 29 of the pull tab 26 which is opposite to that 28 which is adjacent to the notch 25 and which forms the retaining stop for this pull tab, is extended by a jumper 30 in "inverted U" shape.
  • This jumper 30 is designed to ride without friction a conjugated flange 31 which is part of the frame 22 for supporting the drum 1 and which is coaxial with this. latest .
  • An opening or notch 32 is provided in this flange 31 and is positioned there such that the jumper 30 comes to overlap this opening when the drum 1 is in its rest position. None then prevents the sliding of the safety zipper 26 in its slide 27, so that the knobs can be unlocked to adjust them in position.
  • the jumper 30 positively overlaps the fixed flange 31.
  • the arm 11 is then completely locked in its position which corresponds to the locking of the rollers 2 by the stirrup 5 because the puller 26 can in no case slide along its longitudinal axis.
  • the locking of the knobs 2 is then positive because it is ensured even in the event of failure of the return spring 8.
  • the unlocking control finger 18 may be a finger only provided for this purpose, but preferably it is positively incorporated in the franking machine in which it simultaneously plays the role of guide finger: this is for example the case when this machine has a removable head containing the printing drum which is designed to mate with a fixed base which includes in particular the control keyboard.
  • the finger 18 then also serves, in cooperation with the guide opening 20 of the tab 1A, as a relative centering finger of the head and the base.
  • it serves as a guide finger for a set of driving pinions, with associated motors, which are positioned in a tilting module included in the base, this module being tilted towards the head only for the adjustment operations of the knobs and then being guided by cooperation between the finger 18 and the guide opening 20 of the tab 1A of the drum.
