Definitions

  • the present invention relates to devices for inserting pleats in envelopes.
  • Such devices are already known. They are used as office machines to ensure the mailing in envelopes, or come into larger facilities ensuring the automatic processing of large volumes of mail and comprising, in addition, in particular a folder and / or collator and a device for closing loaded envelopes.
  • the empty envelopes are presented successively in a loading position facing a fold transfer path. Each envelope is kept in this loading position for the duration of the insertion of the fold into the envelope.
  • Means for supplying and holding each empty envelope in the loading position are mounted on an envelope path; these means may include a set of rollers and a set of associated pressure counter-rollers, receiving the envelopes between them and arranged at the end of the fold transfer path.
  • the set of rollers, when driven, and the set of pressure counter-rollers contribute to bringing each envelope into the loading position, driving the body of the envelope until the line of junction between the body of the envelope and the previously unfolded flap is received between them.
  • the set of rollers then no longer being driven, the casing is stopped and maintained in the loading position facing the fold transfer path.
  • Opening fingers of the envelope body are used to ensure the opening of the envelope body maintained in the loading position, in order to facilitate the insertion of the fold. These fingers are mounted at the front of the loading position and are normally erased. For the insertion of the fold, they are actuated in the open position of the body of the envelope, coming partially to be inserted in the body of the envelope.
  • the aforementioned set of counter-rollers is advantageously mounted retractable opposite the set of rollers, it is put in the retracted position as soon as the set of rollers is no longer driven, to allow actuation in the open position of the fingers.
  • the present invention aims in particular to allow the proper insertion of the folds in envelopes using a very simple mechanism and does not have the drawbacks of space and the aforementioned assembly difficulties.
  • Its subject is a device for inserting folds into envelopes, comprising: a first set of rollers and a first associated set of counter rollers ensuring the supply and presentation of an envelope in a defined position known as loading, facing a fold path, means for advancing the folds on the fold path for advancing a fold towards the envelope in the loading position, means for actuating the first set of counter rollers from a pressure position to a retracted position when the envelope is in said loading position, and means for opening the body of the envelopes, controlled from a retracted position to an open position when the envelope is in said loading position, said device being characterized in that said first set of counter rollers is coupled through a freewheel mechanism to said means for advancing the plies, for its drive with them, said advancing means themselves being mounted at a distance of said first sets of counter rollers less than the length of the folds to be inserted into the envelopes, and being characterized in that it further comprises first means for ensuring detection of partial insertion of the fold into the envelope, coupled to said
  • the means for advancing the folds comprise a pair of second sets of pressure rollers, mounted on the exit from the fold path, and coupled to said first sets of rollers and counter-rollers by a plate fixed fold guide.
  • the first set of counter rollers is carried by a pair of arms mounted articulated on the axis of one of the second sets of rollers.
  • the pair of arms carries a control spacer axis resiliently biased in abutment on a control cam having on its periphery two sections centered substantially opposite one another, for maintaining the first set of counter rollers in pressure position, and alternated with two second profiles to maintain the first set of counter rollers in the retracted position.
  • a first set of rollers 3 and a first associated set of pressure counter rollers 4 define the loading position at the end of the path 1. They are mounted opposite the fold path 2.
  • the first set of rollers 3 driven in rotation according to arrow 3A and its set of counter-rollers 4 under pressure allow each envelope to be brought into its loading position.
  • the first set of rollers 3 is stopped when the envelope arrives with its junction line between its body and its flap, previously unfolded, situated between it and the first set of counter-rollers 4.
  • These sets of rollers and counter-rollers 3, 4 and upstream rollers 5, 6 thus allow the presentation of each envelope in the loading position and its maintenance in this position during the loading operation.
  • a motor 7, called the envelope motor, ensures the advance of the envelopes on the path 1 until they are put in the loading position. It drives the sets of rollers 3 and 5. It ensures after loading, the ejection of each envelope.
  • the fold path 2 is equipped with its own means for advancing folds on this path. These means for advancing the folds in particular comprise a third pair of sets of rollers 8 and 9 in pressure located at the outlet of the folds path 2. Elastic means not shown ensure the pressure maintenance of the set of rollers 8 against the set of rollers 9.
  • This third pair of sets of rollers 8 and 9 is mounted at a distance from the sets of rollers and counter-rollers 3, 4 less than the length of the folds.
  • the sets of rollers 8 and 9 thus directly ensure the partial insertion of each ply into the envelope presented in its loading position.
  • a fixed guide plate 10 is mounted between the set of rollers 8 and the set of counter-rollers 4, for guiding each ply during its insertion.
  • a counter plate 11 between the set of rollers 9 and the set of rollers 3 is associated with it.
  • the sets of rollers 8 and 9 are both shown in streaks. Arrows 8A and 9A translate their drive into rotation. As a variant, only one of these sets of rollers and then in this case the set of lower rollers 8 can be driven.
  • a motor 12, called the fold motor, is coupled to the set of rollers 8 and, optionally, to the set of rollers 9.
  • the set of counter rollers 4 is mounted slightly retractable opposite the set of rollers 3.
  • fingers 13 for opening the body of the envelope are associated with these sets of rollers and counter-rollers 3 and 4. These fingers 13 are mounted normally erased at the front of the rollers and counter-rollers 3 and 4, under the guide plate 10 of the folds. They are actuated according to arrow 13A, when the counter rollers 4 are retracted, taking an open position to be inserted between the rollers 3 and the counter rollers 4 and in the body of the envelope.
  • a cam 14 is assigned to control the counter rollers 4 in their pressure position against the rollers 3 and in their retracted position.
  • Another cam 15 is assigned to control the fingers 13 in their retracted position at the front of the rollers 3 and counter rollers 4 and in their open position.
  • These two cams are mounted on the same control motor shaft 16. It is driven by its own control circuit 17 with stepping motor, according to arrow 16A, ensuring the advance of the cams in synchronism with the different stages of an insertion cycle.
  • the set of counter rollers 4 is coupled to the set of rollers 8 in advance of the folds.
  • Tensioning rollers not shown are associated to the belt 25 for its constant tension, this regardless of whether the set of counter-rollers 4 is in the retracted position or in the pressure position opposite the set of rollers 3.
  • An arrow 4A illustrates the rotation drive of the set of counter rollers 4, either by friction against the set of rollers 3 driven, or either by coupling with the set of rollers 8.
  • the pair of arms 20 carrying the set of counter rollers 4 has its axis of articulation 20A directly defined by the axis of the set of rollers 8 in advance of the folds.
  • This pair of arms 20 extends laterally on either side of the fold guide plate 10; it mechanically couples the set of counter rollers 4 and the set of rollers in advance of the folds, with a pivoting of the first on the axis of the second.
  • each arm 20 forms an end shoulder not referenced.
  • a control axis 30 is mounted as a spacer axis between the pair of arms 20 and passes through the shoulder of each of these arms. This axis 30 extends on the outside of the lateral flanges, such as the flange 31 of the machine; each of its ends carries the aforementioned roller 21 bearing on the cam 14.
  • a small window 31A substantially vertical, is provided in each of the flanges 31 to allow the sliding of the control axis 30 during the command from the cam 14.
  • the arrow 20F shows diagrammatically the pivoting of the pair of arms 20 around its axis of articulation 20A.
  • each arm 20 has, near the sliding window 31A for the axis 30, a projecting finger 32 transverse to its shoulder.
  • a pin spring 33 is mounted on the finger 32, it has a terminal strand which forms a support stop on the control pin 30 while its other opposite end strand is anchored on the edge of the support arm 20.
  • This spring therefore ensures the support of the roller 21 on the cam 14, but also an elastic pressure of the set of counter rollers 4 on the set of rollers 3 to take account of a variable thickness of the folds.
  • the cam 14 has on its periphery two sections 14A and 14C, centered in a substantially opposite direction, of setting and holding the set of counter rollers 4 in the pressure position, which are alternated with two other sections 14B and 14D for setting and maintaining the set of counter rollers 4 in the retracted position.
  • cam 15 does has on its periphery that a section 15A for placing the fingers 13 in the erased position and that a section 15B for placing these fingers 13 in the open position.
  • cams 14 and 15 correspond to specific angular sectors with regard to the controls that they provide.
  • Profiles 14A, 14B and 14D correspond to angular sectors close to 60 ° each and profile 14C to an angular sector close to 180 °.
  • Profile 15A corresponds to an angular sector close to 240 ° and profile 15B to a neighboring sector of 120 °.
  • These cams are also wedged relative to each other so that the roller 21 has just come to bear on the profile 14A when the roller 23 is located substantially three-quarters of the length of the profile 15A.
  • This relative position of the cams corresponds to a so-called reference position of rest of the motor shaft 16; it is given by a disc 18 with a notch 18A with which is associated a detector mounted in an optical fork and shown diagrammatically at 19.
  • This detector 19 provides the drive stop control for the shaft 16 of the cams 14 and 15.
  • a detection lever 35 is assigned to the detection of each ply during its insertion.
  • This lever is articulated around an axis 35A. It has one of its ends 35B mounted as an obstacle at the front of the set of rollers 3 and of the set of counter-rollers 4, through the guide plate 10. It has its opposite end 35C which forms a detection flag.
  • An optical detector shown diagrammatically at 36, detects the flag 35C and indicates the presence or absence of a fold being inserted under its end 35B.
  • This detector assembly 35, 36 makes it possible, from this detection of the presence of a fold, to determine the instant of partial insertion of this fold in the envelope, taking into account the known advance of this fold, then the instant fully inserted.
  • This instant of insertion at the bottom of the fold is preferably given by the return in obstacle of the end 35B of the lever 35, this return being always detected by the flag 35C and the detector 36.
  • This detection assembly 35-36 controls the circuit 17 and it also controls the motor of the folds 12, through a selected time delay or a counter counting down from unitary movements of advance of the fold, not shown, which it triggers, to ensure that this motor 12 stops when the fold is fully inserted into the envelope.
  • the drive shaft 16 of the cams 14 and 15 is rotated, from its rest position given by the disc 18 and the associated detector 19, when an envelope advances towards the loading position.
  • the envelope having arrived in the loading position, the motor 7 is stopped and the envelope is thus maintained for the insertion of a fold.
  • the roller 21 rests on the profile 14A while the roller 23 is on the profile 15A.
  • the roller 21 passes over the profile 14B and the roller 23 over the profile 15B.
  • the set of counter rollers 4 passes into the retracted position; by the section 15B the fingers 13 pass into the open position of the body of the envelope.
  • the folds motor 12 is driven, close to a time delay, as soon as the envelope has arrived in its loading position. It ensures the advance of the fold on the path 2, upstream of the set of rollers 8 and 9, and then, by the set of rollers 8 and 9, the advance of the fold on the guide plate 10 and between the rollers 3 and the counter-rollers 4, then in the envelope. During this advance, the roller 21 rests on the profile 14B; the counter rollers 4 are driven with the feed rollers 8 but are retracted; they have no effect on the fold.
  • the detector assembly 35, 36 has detected the presence of the fold during insertion. From this instant, it allows the control circuit 17 to determine the instant of partial insertion of this fold in the envelope.
  • the detector assembly 35, 36 also makes it possible, when the fold arrives at the bottom of the envelope, to stop the motor 12 and thereby stop the counter-rollers 4.
  • the loaded envelope is ejected according to the arrow 1B, by restarting the motor 7 of the envelopes while the profile 14C still maintains the set of counter rollers 4 in the pressure position.
  • the roller 21 passes over the profile 14D and the set of counter-rollers 4 returns to the retracted position. This allows processing of the loaded envelope during its ejection, during which each envelope can be driven in reverse, in the opposite direction to the arrow 1B, while the set of counter-rollers 4 must remain without effect. After this treatment, the loaded envelope is again driven along arrow 1B and the roller 21 passes over the profile 14A for the return of the set of counter-rollers in the pressure position.
  • the control circuit 17 of the shaft 16 ensures the control of the advance of the cams in synchronism with the different stages of an insertion cycle.
  • the arrival of the shaft 16 in its reference position, detected by the detector 19, causes its drive to stop. He will again be trained on a full turn for a new insertion cycle.
  • this insertion device lies in the simplicity of the insertion mechanism and its control, their ease of assembly and their very small footprint. This mechanism and its control are also very robust and reliable. The mechanism is of low inertia.
