Definitions

  • the present invention relates exclusively to the field of mail processing and more particularly relates to an envelope flap selection device integrated with a mail item supply module of a mail processing machine.
  • an envelope flap moistening device for integration with an envelope feeder module of a franking machine and having a separator for separating the flap from the body of the envelope and suction means arranged just in front of the separator for, in cooperation with a presser finger, press the envelope towards these suction means and detach the flap from the body of the envelope and thus facilitate its passage under the separator .
  • This device gives overall satisfaction for all types of envelopes. However, after a very large number of envelopes pass, there is some relaxation in the pressure exerted by the pressure finger. In particular, when a previously closed envelope is imperfectly glued with a partially open flap, the front of this flap will behave as an open flap and will fit under the separator until encounter a start of glued area that will block its progress and thus cause a jam of the power module.
  • a subject of the present invention is therefore an envelope flap selection device for mail processing machine feeder which avoids any jamming resulting from poorly closed envelopes and ensures proper closure of all envelopes.
  • An object of the invention is also to provide a device for a supply of envelopes with a very high rate of treatment.
  • a flap separation device in a mail processing machine feeder characterized in that it comprises blowing means arranged under a transport table of the mail items of the feeder to generate a flow of air directed inwardly of the flap and said transport table of the mail items is spaced from a reference wall of the feeder by a distance D equal to at least the largest width of flap glued by a wetting device of the feeder and a length L equal to at least the longest length of flap glued by said wetting device.
  • said blowing means comprise at least one turbine pulsating ambient air in an air distribution pipe, an outlet mouth of said duct having a substantially triangular flattened profile adapted to provide a stream of cooling air under the body of the envelope.
  • said vertical referencing wall comprises a fixed deflector for, in cooperation with a body of moistener partially having a complementary shape, fold the flap from a vertical position obtained by said blowing means to an inclined position adapted to allow wetting of the flap by said wetting device.
  • the invention also relates to the mail item feeding module of a mail processing machine comprising an envelope flap separating device as mentioned above.
  • the invention also relates to a method of separating flaps in a mail processing machine feeder in which the separation of the flap from the body of the envelope is effected by completely releasing the flap of this body from the envelope and placing the flap thus released against a vertical referencing wall of the feeder by means of a flow of air directed towards the inside of the flap.
  • said total release of the flap is obtained by separating a transport table of the mail items from the feeder of said referencing wall by a distance D equal to at least the largest flap width glued by a device. wetting of the feeder and over a length L equal to at least the largest length of flap glued by said wetting device.
  • Said distance D can be between 50 mm and 100 mm and said length L between 230 mm and 334 mm.
  • said air flow is generated by blowing means arranged under said transport table of mail items.
  • said vertical referencing wall comprises a fixed deflector for, in cooperation with a moistener body having in part a complementary shape, fold the flap of a vertical position obtained by said blowing means to an inclined position adapted to allow wetting of the flap by said wetting device.
  • the figure 1 schematically shows in a schematic view a mail item feeding module to be arranged at the entrance of a mail processing machine. Such a module can of course also be integrated directly to this machine.
  • the mail items 10 that can be processed by this module are of all types (we speak of "mixed mail” mode) including envelopes with open flaps at 90 ° (also called nests), flaps folded and closed or flaps closed. But, it can be also simple documents (for example in A4 format), business cards, postcards, labels or inserts of variable format and thickness, which will then be directly printed with a postal imprint.
  • a power supply module comprises four work zones succeeding each other from upstream to downstream with respect to the advancement direction of the mail articles: a reception and stack storage area of the mailpieces 12, a zone d one-to-one extraction and selection of these mail items of which only the last row 14 of the lower selection rolls is shown, a flap separation area 16 for separating the flap from the envelope 10A from the body of the envelope 10B and a wetting zone 18 for moistening this flap once the flap 10A is separated from the body of the envelope 10B.
  • the wetting is for example carried out by means of a jet wetting ramp, a brush or a brush 18A whose end rests on the surface of a water tank 18B disposed under a transport table 20 mail items through the feed module.
  • the wetting of a flap is performed during the passage of the flap between the brush and the reservoir, the envelopes closed, which must of course not be wet passing over the brush carried by the body of the moistener 18C whose upper surface is aligned with the transport table.
  • Driving means conventionally rollers 22 which are flush through the transport table 20, allow the envelopes to be transported during the separation and wetting phases of the envelope flaps and then convey them to the next module of the mail processing machine, in principle the franking module (not shown).
  • the input rollers of this franking module act as means of closing the envelopes previously moistened, to unless the power module has output of its own closure means.
  • the zone of separation of the flaps is devoid of a separating element, the separation of the flaps of envelopes being carried out simply by a flow of air directed towards the inside of the flaps, emanating from blowing means 24 arranged under the transport table, and which has the effect of folding back to 90 ° against a referencing wall 26 the only flaps envelopes folded flaps not yet glued, the flap of nestled envelopes being already open at 90 ° (and place in a groove 28 adjacent this reference wall).
  • This air flow has no effect on the already closed envelopes that are going to be directed above the mooring zone, whether or not this closure is carried out entirely, that is to say on only part of the length of the envelope, for example 2/3 of this length.
  • the selection zone must have a length L at least equal to the length of an envelope in the international format DL (by incorporating a margin of 10 mm), ie approximately 230 mm and preferably between 230 and 334 mm, the latter dimension corresponding to a C4 format envelope margin of 10 mm included, and the transport table 20 is spaced from the reference wall by a distance D at least equal to the largest width of a flap corresponding to a triangular flap of a large format envelope is about 100 mm and preferably between 50 and 100 mm. It will be noted that these dimensions are essentially a function of the type of envelopes processed by the machine,
  • the blowing means are advantageously constituted by two turbines or individual fans 26, 28 loaded, under the action of a control unit (not shown), of separately pulsing ambient air in two air distribution ducts 30, 32.
  • the outlet mouth of each pipe 30A, 32A has a substantially triangular flattened profile adapted to provide a stream of air rasing under the body of the envelope directed towards the inside of the flap. These two outlets are offset vertically, the pipe closest to the wetting zone having a slightly lower disposition for reasons of space.
  • the operation of the feeder whose flap separation zone has been modified according to the invention is as follows.
  • the envelopes extracted one by one from the stack, whether opened or closed, are, when they are advanced in the separation zone 16, subjected to the blowing means 24 which will have the effect of opening at 90 ° the flap of each of the unglued envelopes. and to press it against the referencing wall 26.
  • a fixed deflector 34 shaped delta wing fixed or forming a part of this reference wall will, in cooperation with the lower face of the body of the moistener 18C having a complementary profile, to guide and fold down the flap of these envelopes, like that of nested envelopes, from the 90 ° position where they are then at a terminal position close to 30 ° allowing their passage under the wet brush of the moistener and therefore their mooring in the best conditions (see figure 3 ). It will be noted that with one flap envelope imperfectly closed, the air flow is not sufficient to detach the flap that will remain glued to the body of the envelope, which will then pass over the body of the moistener as a closed envelope without causing any jam.
  • blowing means described consist of two independent turbines, it is obvious that it is conceivable to use only one turbine provided that it generates an air flow large enough to allow remove and maintain the flaps of the open envelopes at 90 °.
