Definitions

  • the present invention relates to an office machine intended to produce envelopes for mail folds, as and when these folds are made.
  • Automatic mail processing facilities are complex and bulky; they must respond to high processing rates while being reliable. They have internal document paths, envelopes initially empty and envelopes loaded to close, coupled to each other at the inserter that each of them has. These paths are long and with complicated trajectories to facilitate the execution of the operations to be performed on each of them.
  • the present invention aims to meet its objectives by proposing an integrated document folding office machine and envelopes loading which carries out envelopes of mail folds, as and when they are made.
  • the first and second paths are defined inside the upper frame in which they intersect and on which the entry of folds and the entry of envelopes are on its upper part, with the entry of more pleats at the front as the entry of envelopes.
  • the machine comprises a reversible motor for driving the envelopes on said second and third paths, coupled to a control circuit ensuring, from a position detection of each envelope on said third path, the immobilization of the envelope in a defined loading position in the loading module for its loading, the advance of the loaded envelope on the third path to a defined closed position and the retraction of the envelope on said third path for its complete closure.
  • the closing means comprises a pair of pressing rollers pivotally mounted facing the third path and controlled between a rest position outside the third path during the advancement of the envelope on the third path and a working position on the third path, with said pressure rollers on either side of this third path, during the retraction of the envelope on this third path.
  • the office machine illustrated in FIG. 1 is intended to ensure the envelopes of mail folds, preferably as and when these folds are made. It is part of the equipment of a secretarial workstation where it constitutes one of the machines available to the person working at this workstation. Such a secretarial position has not been illustrated.
  • the machine according to the invention is simply placed on the work plan of the station while being made easily accessible for the person at this station, in particular for the presentation of the folds of which it ensures the enveloping.
  • the machine has an entry 1 for folds, a magazine for 2 envelopes empty and an outlet 3 of loaded and closed envelopes, which are formed on a machine frame 5.
  • the chassis 5 is formed in two parts called the upper chassis 5A and the lower chassis 5B.
  • the lower chassis has its open underside and is mounted articulated on the lower chassis 5B with an open upper face, around an axis 5C. This 5C axis is carried by the lower chassis and is close to its rear wall, considering the machine installed in a secretarial position.
  • the lower chassis 5A is also locked on the lower chassis 5B which it then closes, by known unlockable means, not shown.
  • the entry 1 of the folds and the store 2 of empty envelopes are defined on the upper wall of the upper frame 5A, with the entry 1 more at the front than the store 2 of empty envelopes.
  • the outlet 3 of the loaded and closed envelopes is defined at the bottom and at the front of the lower chassis 5B.
  • the folding module 11 has two folding pockets 12 and 13 associated with a set of folding rollers 14.
  • This path 10 defines the trajectory of the folds transferred from the entry 1 to the folding module 11. It forms a bend guiding the folds from the entry 1 towards the rear part of the lower chassis 5A, to supply the folding module, mounted in part in the rear part of the chassis 5A and for the other part in that of the chassis 5B.
  • This folding module itself ensures at the end of the path 10, a folding of the path of the folds during the folding that it performs.
  • the store 2 of empty envelopes, constituting the entry of empty envelopes, corresponds to a path 20 of the empty envelopes in the machine.

Its flap opens when it leaves the rollers 22A and counter-rollers 22B, and is retained by the edge of the deflector 21 to open completely. It passes completely open and flat behind the body of the envelope opposite the detector 25.
  • the control circuit 6 stops the motor 30A.

  • Phase 2 is called the fold transfer and folding phase.
  • This phase 2 is triggered for the first aforementioned value of the counting state possibly followed by a first time delay.
  • the control circuit 6 then starts the motor 10A. In their angular position of 90 °, the cams put the counter-rollers 15B under pressure against the rollers 15A while the shutter fingers 18 disappear and open the inlet chute 1 on the path 10.
  • the fold present in the inlet chute 1 is transferred along the path 10 and enters the folding module 11 which delivers it suitably folded on its outlet 11B. On exit 11B, the fold is always driven by the rollers of the folding module and advances towards the open envelope in the loading module 31.
  • the detector 40 detects the passage of the front edge of the folded fold at its level. Its signal transmitted to the control circuit 6 gives rise to a temporary stop of the motor 10A.
