Definitions

  • the present invention relates to machines for inserting folds into envelopes. It relates more particularly in such machines to a device for opening the body of successive envelopes with a view to the insertion of a fold in each of these envelopes.
  • means for advancing envelopes ensure the supply and presentation of the successive envelopes to be loaded in a defined loading position, facing a fold path .
  • Each of the folds is advanced on its way and then inserted into the envelope while waiting in its loading position. After loading, the envelope concerned is ejected.
  • the envelope flap is unfolded.
  • the envelope placed in its loading position has its flap retained unfolded so as not to interfere with the execution of the fold insertion operation.
  • opening fingers of the envelope body mounted normally erased in front of the envelope in the loading position, are actuated in the open position to partially insert into the body of the envelope and open it before inserting the fold.
  • These fingers are generally mounted at the end of an actuating arm controlled in synchronism with the progress of an insertion cycle, for erasing the fingers and placing them in the open position.
  • the prior German patent DE- 31 37 033 (PITNEY BOWES) describes an insertion machine where the insertion station is defined on a U-shaped tray.
  • the empty envelopes to be loaded are deflected on the periphery of a first roll of drive with which two guide rollers are associated; a pivoting lever mounted between these two rollers at the same time ensures the opening of the envelope flap.
  • a second roller and a guide deflector extend the action of the first roller to place each envelope on the tray in the loading position in which the back of the envelope rests on the tray while its flap rests against an inclined plate extending the guide deflector at the front of the plate.
  • the device for opening the body of the envelope comprises first opening fingers of conventional type, which are normally retracted at the front of the tray and are inserted into the body of the envelope in the loading position. It further comprises L-shaped vacuum fingers, pivotally mounted facing the U-shaped plate to be at a distance from the plate or resting on the body of the envelope in the loading position. These vacuum fingers apply the body of the envelope against the U-shaped plate against the effect of the inclined flap retaining plate. These vacuum fingers are controlled by a camshaft, itself controlled by an electromagnet through a coupling mechanism, when the envelope is detected in the loading position. They are put back to rest when the envelope leaves the loading station. Each finger is articulated at two points on two pivoting levers, one of which is controlled.
  • the loading mechanism is with RAM for inserting the folds.
  • the insertion machine described in US Pat. No. 2,736,999 allows sheets to be assembled on a RAM which insures their insertion into an envelope. It includes an endless conveyor with gripping push fingers, mounted under the tracks for the different types of sheets. These fingers collect the sheet present at the exit of each path. They drive the leaves taken to the RAM mounted at the end of the conveyor and facing an open envelope awaiting loading on an insertion station.
  • the envelope received open has its flap retained on a front plate and held in abutment against this plate by pivoting fingers. His body is in turn kept open by fingers mounted at the end of a pivoting arm.
  • the object of the present invention is precisely to produce a device for opening the body of the envelopes to be loaded, very simple to produce and to be mounted in an inserting machine made very easy, and having only a very small control mechanism size.
  • a device for opening the body of envelopes for loading entering a insertion machine in which each envelope to be loaded is maintained in a so-called loading position facing a fold path
  • said device comprising opening fingers coupled to actuation means themselves coupled to control means, to ensure that the opening fingers are placed in the retracted position and in the open position, facing the envelope in said loading position
  • the insertion machine comprising along said fold path a guide plate mounted opposite said opening device forming a preassembled assembly
  • said device being characterized in that the preassembled assembly is formed on an axis single said axis of the fingers, with said opening fingers mounted free to rotate directly on said axis of the fingers and with said axis of the fingers equipped with first positioning means longitudinal, for each finger, and second elastic stop means extending on the same side of said axis of the fingers, for each finger, and in that said guide plate is mounted opposite said preassembled assembly by opposing to the action of said second elastic means on the fingers and guiding the fingers against one of its faces, when they pass from their
  • the guide plate is a plate coupling said path of the folds to the envelope in said loading position, in the insertion machine, said guide plate partially covering said assembly.
  • said axis of the fingers further comprises at least one sliding pad under said guide plate, for maintaining the orientation of said axis of the fingers.
  • said axis of the fingers carries, in addition, two longitudinal slides in which it slides and which allow the direct mounting of said assembly in the insertion machine.
  • two rings and a spiral spring ensure the longitudinal positioning of each opening finger on the axis of the fingers and one of the end strands of the spring extends laterally opposite the opening finger concerned and at its end folded under the finger to ensure its retention.
  • FIG. 1 the general organization of an envelope loading station has been illustrated, in an inserting machine equipped with a device for opening the body of the envelopes according to the present invention.
  • 1 indicates a path of empty envelopes to be loaded and 2 a path of the folds.
  • the arrow 1A indicates the advance of an empty envelope to be loaded, on path 1, for its presentation and its maintenance in a defined loading position, facing path 2 of the folds.
  • the arrow 2A indicates the advance of a fold on the path 2, for its transfer to the envelope awaiting loading and its insertion into the envelope.
  • a first set of rollers 3 and a first associated set of counter rollers 4 contribute to the advance of each envelope to its loading position and ensure that it is held in this position during loading.
  • a pair of second sets of pressure rollers 5 and 6, slightly upstream on path 1, ensures the retention of the envelope flap previously unfolded when the envelope is in its loading position. Suitable means, not illustrated, make it possible to unfold the envelope flap during the advance of the envelope on path 1.
  • a motor 7, known as the envelope motor, ensures the advance of each envelope. It is coupled in particular to the first set of rollers 3 which it drives along arrow 3A and stops when the envelope is in the loading position.
  • the loading position corresponds to the passage of the body of the envelope between the first sets of rollers and counter-rollers 3 and 4, for which the junction line between the body of the envelope and its unfolded flap is between these first sets of rollers and counter-rollers 3 and 4.
  • a pair of third sets of rollers 8 and 9 contributes to the advance of each of the folds on path 2, which is to be inserted in the envelope awaiting loading.

It is blocked by a screw 46, or the like, on the axis of the fingers, without freedom of rotation; it constitutes an orientation pad for the axis of the fingers 35.

It also forms the guide plane of each finger under the plate 10, when the fingers are actuated from their retracted position to their open position and vice versa. In addition, when the fingers are actuated in the open position, this face 54A progressively escapes in the corresponding notch 50, to make it possible to accentuate the effect of the spring 38 and to cause a slight pivoting upwards. from part 55 of each finger.

  • each of the levers 22 is constituted by an arm articulated at the bottom of the machine and the opposite end of which forms a fork 22B for direct reception of the end parts of the axis of the fingers 35.
  • the axis of the fingers 35 is retained in this fork 22B by the guide plate 10.
  • This same guide plate 20 also closes the upper edge of the housing of each slide 40 provided in the flanges and then prevents any release of this slide.
  • Each of the levers extends over the external face of each of the lateral flanges 31 of the machine.
