Definitions

  • the present invention relates to the field of mail processing and more particularly relates to an envelope supply module provided with an improved device for conveying and closing envelope flaps.
  • the closure of the envelope flaps in a traditional mail processing machine is performed by the pressure of the extraction rollers arranged at the output of the envelope supply module of this machine, the internal face of these flaps having been previously wet by a moistening device disposed just upstream of these rollers on the transport path of these envelopes (see, for example, GB-A-191227233 ).
  • the present invention therefore aims to overcome these defects in the closure of the envelopes by providing a supply module of mail items provided with a device, both simple and reliable, closing the envelope flaps avoiding smearing .
  • Another object of the invention is to propose a device that allows a closure of envelopes without recourse to additional external means.
  • Yet another object of the invention is to propose a device which does not imply an increase in the initial bulk of the power supply module.
  • an envelope supply module for a mail processing machine comprising conveying means for transporting these envelopes through the feed module, separation means for selecting these envelopes one by one, means for separating the envelopes. moistening to wet a flap of the thus selected casing and closing means to ensure by pressure the closure of the casing and its ejection out of the supply module, characterized in that said closure means comprise two rolls of superimposed extraction each having on a width corresponding at least to the width of a printing area of the postal pattern a ribbed portion which is made of a hydrophobic material.
  • said ribs of said upper extraction roller and those of said lower extraction roller are staggered so that there can not exist contacts between them when closing said envelope.
  • Said extraction rollers may each comprise a ribbed portion over a length greater than the width of said flap.
  • Said hydrophobic material is chosen from the following materials: polyoxymethylene, expanded polystyrene, teflon®, silicone versilic®.
  • Said extraction rollers further comprise a remaining smooth part made of a material with a high coefficient of friction in order to ensure a good conveying of the envelopes.
  • said ribbed portion and said smooth portion are mounted on a common axis of rotation and there is provided, disposed at least under said ribbed portion of said lower extraction roller, a squeegee to evacuate excess water to a gutter to ensure recycling.
  • said gutter further extends under said smooth portion of said lower extraction roller.
  • Said extraction rollers are preferably mechanically connected to said envelope conveying means by means of a motion transmission mechanism.
  • the invention also relates to a mail processing machine comprising such a power supply module. It can be a postage meter as a folding machine and insertion.
  • the figure 2 illustrates very schematically a supply module 10 in envelopes 12 of a mail processing machine of the prior art.
  • This power supply module comprises a series 100 of drive rollers which direct the envelope 12 (slightly inclined and tipped at the rear at a feed tray 14 having a stack of these envelopes) towards and under separating means 102 conventionally comprising a die 104 and superposed selection rollers 106, 108 ensuring a one-to-one selection of the envelopes.
  • Conveying means including in particular a pressing assembly 110 and superimposed driving rollers 112, 114 transporting each selected envelope to wetting means 16 ensuring the wetting of the envelope flaps.
  • such a device comprises a separator 140, a fixed portion 142 is secured to the body of the feeder and an articulated portion 144 is provided with a brush 146 whose bristles, directly in contact with a wetting tank 148 in the absence of envelopes, are then moisten the inner portion of the flap of these envelopes after it has been removed from the body of the envelope by the separator 140.
  • a vertical wall 150 parallel to the envelope transport direction forms a referencing wall for lateral guidance (jogging) of these envelopes.
  • two superposed extraction rollers 116, 118 mechanically connected to the transport rollers 112, 114 and the pressing assembly 110 by a mechanism 120 for transmitting motion.
  • This mechanism 120 makes it possible to transmit the spacing of the transport rollers, depending on the thickness of the envelope, to the extraction rollers 116, 118 in a given reduction ratio chosen to simultaneously provide for the taking into account of a thickness. envelope variable and the maintenance of a pressure stress sufficient to press the flap of the envelope against the body thereof, and that gradually.
  • connection means 18 are furthermore provided at the output of the power supply module 10 to ensure, within the mail processing machine, a mechanical connection and continuity of the electrical connections with the immediately following module, for example a module franking 20, of which only the two superimposed take-up rolls 200, 202 are shown.
  • the extraction rollers are not uniformly smooth but each comprises mounted on a common axis of rotation 30, 32 a ribbed portion 34, 36 whose width corresponds at least to the width of the printing area of the postal imprint (typically slightly greater than the width of a standard trapezoidal type flap) and which is made of a hydrophobic material, such as polyoxymethylene, expanded polystyrene, teflon®, or silicone versilic®, the part remaining 38, 40 of these rollers is as previously smooth and made with a high friction material such as natural rubber, silicone or polyurethane to ensure a good conveying envelopes.
  • a hydrophobic material such as polyoxymethylene, expanded polystyrene, teflon®, or silicone versilic®
  • the ribs of the upper extraction roller and those of the lower extraction roller are staggered so that there can be no contacts between them in that part of the rollers closest to the referencing wall 150. no water deposit can be produced on this part of the upper extraction roller and therefore also on the upper part of the envelope on which the postal impression will be printed.
  • a squeegee 42 preferably silicone or polyurethane to scrape any excess water present on the extraction rollers lower that evacuate this water to a gutter 46 to ensure recycling, for example to the wetting reservoir 148.
  • This gutter can also be advantageously extended under the smooth portion 40 of the lower extraction rollers and then include another squeegee 44 .
  • the operation of the power supply module according to the invention is as follows.
  • the loaded envelopes inserted by stack in the feed module from the loading tray are, after selection one by one, directed towards the separator of the wetting device where the flap is first removed from the body of the envelope before the flap is wetted by the brush.
  • the envelope is then extracted by the extraction rollers between which it is also simultaneously closed before ejection from the supply module, for example to the franking module disposed downstream.
