Definitions

  • the present invention relates to the field of mail processing and more particularly relates to a mail item selection device implemented in an automatic feeder module, or feeder, a postage meter franking machine.
  • a franking machine must be adapted to receive different types of mail items such as documents, folds or envelopes having greater or lesser thicknesses, typically from 0.1 mm to 16 mm.
  • it often has upstream of an automatic power supply module, in particular for conveying these mail items at different speeds and usually comprising means for receiving / stacking, selecting, transporting and possibly closing these items. mail items.
  • the document EP-A-0 195 348 discloses a mail item selection device for separating the mail items one by one from a stack of mail items and transporting them downstream, having a first die in the form of a flexible tongue cooperating with a plurality of opposed selection rollers for selecting one by one said mail items and transporting them downstream, said first die being pivotable about a first axis of rotation against a first resilient biasing means and having a shape of comb.
  • the present invention aims to overcome the disadvantages resulting from the passage of duplicate envelopes by proposing a device for selecting mail items for franking machine feeder which can limit in a proportion of at most 1 in 1000 such a double passage.
  • a mail item selection device for separating the mail items one by one from a stack of mail items and transporting them downstream, characterized in that it comprises at least one first die cooperating with a plurality of opposed selection rollers for selecting one by one said mail items and transporting them downstream, said first die being pivotable about a first axis of rotation against a first means resilient return member and having a comb shape of which one end of at least one tooth is coated with a material resistant to wear.
  • said material is a ceramic or a carbide.
  • it may further comprise a second die pivotable about a second axis of rotation against a second elastic return means.
  • said second axis of rotation and said first axis of rotation may form a common common axis of rotation or said second axis of rotation may be offset upstream with respect to said first axis of rotation.
  • said second die has a comb shape on each of which teeth is fixed an elastomeric blade.
  • the invention also relates to a mailing machine feeder for mailing machines comprising a device for selecting said mail items.
  • An automatic mailing material supply module conventionally comprises a feed zone consisting essentially of a tray intended to receive a pile of mail items and comprising first transport rollers for driving these mailpieces downstream. (and against a referencing wall) at a separation zone comprising a separation device in which these mail items are extracted one by one from the stack of articles. Second transport rollers are generally provided at the exit of this separation zone for conveying the mail articles thus extracted downstream.
  • Such automatic feeder is for example illustrated in the European patent cited in the preamble of the present application.
  • FIGS. 1 and 2 show more specifically a device according to the invention for separating mail items 10 which essentially comprises a first die 12 followed by a second die 14 both cooperating with several opposite selection rollers 16A, 16B, 16C to select a mail piece and only one and carry it downstream.
  • the first and second dies are articulated around a common axis of rotation 18 and can each pivot against resilient return means, for example the compression springs 20A, 20B; 22, when passing mail items on the selection rollers.
  • resilient return means for example the compression springs 20A, 20B; 22, when passing mail items on the selection rollers.
  • These two elastic return means are each also supported on a frame portion 24 of the selection device.
  • the second die preferably further comprises an operating lever 26 to allow an operator to manually clear the transport path of the mail items during the processing of mail items of large thickness, typically greater than 6mm and less than 16mm (threshold classic maximum selection of a feeder). Indeed, without this possibility of withdrawal, the Elastomer blade may wear more quickly and damage fragile envelopes, such as window envelopes. In addition, for these thick envelopes, the selection can be made perfectly by the first die alone without any risk of double pass.
  • a tension spring could also be suitable subject to a configuration of attachment of the spring to the different frame.
  • the manual operation of the second die by means of the operating lever 26 can be replaced by an automatic operation (not shown) provided that a combined displacement of the two dies can be obtained by decoupling the two axes of rotation of these two dies, the axis of rotation of the second die being offset upstream relative to the axis of rotation of the first die, and providing that the first die comprises at least one support intended to cooperate with at least one stop of the second die, so that, beyond a predetermined thickness of mail items, a displacement of the first die will cause an automatic and progressive movement of the second die.
  • the first and second dies 12, 14 are not arranged perpendicular to the transport path of mail items but inclined downstream of about 45 °. They each have a comb shape, each of the teeth being arranged between two adjacent selection rollers. In the illustrated example which comprises three selection rollers (not shown), the first die has four teeth and the second only two teeth.
  • the end of at least one tooth, and preferably the ends of the two central teeth or of each of the four teeth is coated with a material resistant to wear, as a ceramic or a carbide, forming a selection finger 12A while on the second die 14, each tooth is provided with an elastomer blade 14A.
  • the elastomer blade has a very high coefficient of friction to ensure the best possible contact with the mail item but wears relatively quickly and may damage, by crumpling or stuffing, the mail items more fragile while the ceramic finger is wear-resistant while limiting the risk of scratching of mail items.
  • each finger 12A of the first die 12 is preferably a titanium oxide, such as Ti-Cord from the French company Saint-Gobain, deposited by thermal transfer. This results in a very high hardness of the ceramic finger that can be maintained in place throughout the life of the feeder and the roughness of the material is sufficient to hook the mail items while preventing a possible tearing during their passage .
  • the operation of the selection device according to the invention is as follows.
  • the mailpieces to be treated being arranged on the tray of the feed device, for mail of small thickness, that is to say the thickness of which is less than 2mm, and for mail of standard thickness, c that is to say, whose thickness is between 2 and 6 mm, most of the selection work is performed by the first die, the second die which remains subject to its return spring 22 catching if necessary the possible double passages .
  • the second die can be active or preferably not active, which will prevent this second die on which acts the return spring 22 premature wear by repeated shocks with the mail piece and a crumple of the most fragile mail items, such as window envelopes.
  • the roughness of the ceramic material makes it possible to select the mail items very efficiently without scratching them and its hardness avoids premature wear. It thus becomes possible for envelopes of small thicknesses to abstain from the use of a second die for example by using an operating lever. The periods of unavailability of the feeder are reduced.
