Definitions

  • the present invention relates to the field of mail processing and relates more particularly to a device for transporting and driving mail items which may have variable thicknesses.
  • a franking machine must be adapted to receive different types of mail items such as documents, envelope envelopes or packages having greater or lesser thicknesses.
  • European patent application EP 0 382 497 shows such a franking machine, the base of which is provided, in addition to an inlet supply roller and an outlet ejection roller, with a free complementary roller and mounted flexible to cooperate with the ejection roller and thus allow, by adjusting the vertical distance between this movable roller and the ejection roller, taking into account the variation in thickness of the driven article.
  • the transport device 2 comprises a motorized input roller 4 acting against a counter roller 6, it frequently occurs blocking of mail items entering this transport device because an article having a thick 8 comes first to abut against the counter-roller 6 and lifts it, which tends to cause the immobilization of this article of mail before it comes into contact with the motorized roller 4 intended to drive it, inside a base 10 of the franking machine, to the printing mechanism.
  • the present invention aims to overcome these drawbacks by proposing an automatic drive device for mail items, arranged just upstream of the printing mechanism, and provided with means allowing optimum consideration of variations in thickness of these mail items.
  • a device for driving mail items along a transport path of a postage meter base a device arranged upstream of a printing mechanism and comprising first and second rollers.
  • motorized drive co-operating with associated movable counter rollers mounted on articulation means which can pivot about a common articulation axis against return springs fixed to attachment support means, the at least one of the counter-rollers comprising a median counter-roller mounted on a lever articulated around the common axis and surrounded by two twin external counter-rollers each mounted on a lever also articulated around the common axis, so that the mail items introduced into the transport path according to whether or not they respectively have a thickness less than a predetermined thickness are in contact with only one of the outer counter-rollers nes or of the median counter-roller or all of these counter-rollers.
  • the articulation levers of the outer counter rollers are advantageously made integral with one another by means of a spacer.
  • the articulation levers of the external counter-rollers comprise a polygonal notch intended to cooperate with the two faces of a stop to define the upper and lower limits of pivoting of these levers.
  • the upper stop position is fixed by the structure of the transport path for mail items in the franking machine and the lower stop position determines the thickness from which the counter rollers act together.
  • the counter-rollers are mounted in cantilever at one end of their respective articulation lever.
  • the counter-rollers have a determined radius smaller than that of the associated motorized drive roller, so that that, when introducing a document into the base of the franking machine, the document is driven by the motorized roller before coming into contact with the counter-rollers.
  • blocking of these documents at the input of the drive device can be avoided.
  • FIG. 3 represents a device for driving mail items of the prior art arranged in the base 10 of a franking machine upstream of a printing mechanism (not shown) .
  • This drive device 2 comprises first 4 and second 14 motorized drive rollers mounted on a fixed support 12 and which face two movable counter rollers 6, 16. These counter rollers are held at one end of shaped means forks 18, 20, articulated around a common axis 22 and which can pivot against return springs 24, 26 fixed between the other hook-shaped end 28, 30, of these forks and an axis common attachment 32 secured to a flange 34 of the base 10 of the franking machine. In the rest position shown, in the absence of any mail item and under the action of the return springs 24, 26, the rollers and counter-rollers are in contact with each other temporarily closing a transport path 36 of these mail items.
  • FIGS. 1 and 2 respectively represent in sectional elevation and in top view a mail item driving device according to the invention 40 also arranged in the base 10 of a franking machine upstream of its printing mechanism.
  • this device 40 which are common with those of the drive device 2 of the prior art will bear the same references.
  • the drive device 40 comprises, as before, first and second motorized drive rollers 4, 14 for the transport of mail items 8 which face sets of movable counter rollers.
  • the first motorized roller 4, disposed at the input of the drive device 40 now cooperates, no longer with a single counter-roller, but with a set of counter- rollers 42, 44, 46 whose radius or positioning is advantageously determined so that, when introducing a mail item 8, the latter comes into contact, first, with the motorized drive roller 4 .
  • This set of counter-rollers comprises, in the preferred embodiment illustrated, on the one hand a central or median counter-roller 44 mounted in flexible overhang at one end of a median articulation lever 50 of which the other end, advantageously in the form of a hook, is connected to a return spring 56 fixed to the common fastening support axis 32 and, on the other hand, by and from this central counter roller , two external counter-rollers 42, 46 also each mounted in flexible overhang at one end of a respective articulation lever 48, 52 the other end of which, advantageously in the form of a hook, is connected to a spring 54, 58 also attached to the fastening support pin.
  • the three articulation levers of these counter rollers can pivot around the common articulation axis 22.
  • Each of the articulation levers carrying the outer counter-rollers comprises a polygonal notch 60 intended to cooperate with the two faces of a stop 62, 64 secured to the base of the franking machine to fix high and low limits to the pivoting of these levers.
  • the upper limit is determined by the maximum admissible thickness for mail items, taking into account the material structure of the transport path 36 in the franking machine.
  • the lower limit which may depend on the type of mail used will define a predetermined thickness from from which a joint action of all the counter-rollers will become possible. Indeed, below this low limit, only the median counter-roller is in contact with the document transported.
  • a spacer 66 integral with these two articulation levers at each of its ends makes it possible to guarantee a simultaneous movement of the external counter-rollers associated with these levers.
  • this spacer is placed substantially in a plane passing through the axis of articulation 22, perpendicular to the plane defining the transport path of the mail items, and above the central articulation lever 50, which allows this the latter to raise the external articulation levers when a document of considerable thickness is introduced into the drive device 40.
  • the operation of the device according to the invention is as follows. At rest, the drive device 40 is in the position of FIG. 1, the central counter roller 44, under the effect of the return spring 56, is under pressure against the motorized drive roller 4 while the counter -external rollers 42, 46 are separated from this drive roller by a determined space resulting from the lower abutment of the articulation levers 48, 52 of these counter rollers.
  • this document will be taken between the motorized roller and one or more counter rollers.
  • this document will be taken between the motorized roller and one or more counter rollers.
  • the median counter-roller 44 comes into contact with the document being transported, thus allowing the application of light pressure on this document.
  • the three counter-rollers 42, 44, 46 are together in contact with the document, which makes it possible to exert greater pressure.
