Definitions

  • the present invention relates to a device making it possible to produce a homogeneous stack of flat objects, in particular mail envelopes delivered by a conveyor coming from a machine for processing this mail, these envelopes all being on one of their edge and in the same direction but which may correspond to different formats, weights or thicknesses and also be present at the entrance of the device according to any formation, being separated from one to the other or on the contrary being partially overlapping to form a continuous line.
  • the present invention relates to a stacking device which overcomes these drawbacks, by allowing the stacking of objects one by one or in tiled formation, whatever the speed of supply of these objects. It also allows manual or automatic access to one end of the stack during formation, with in addition a minimal dispersion of the qualities of homogeneity of the stack and offset of the envelopes compared to a reference dihedral against the planes of which those -these build as the stack is created.
  • the device considered comprising a conveyor delivering the objects and in particular mail envelopes one by one, separated or with a mutual covering of each of these envelopes by the following, and a stacking head carried by a carriage mobile as the stack is formed, this carriage comprising at least one strip made of a material with a significant coefficient of friction, controlled in continuous rotation to drive the envelopes in its movement, these being presented with one of their edges resting on a horizontal plane in the direction of a vertical jogging plane forming with the horizontal plane a reference dihedral, is characterized in that the strip of the stacking head is mounted on four rotary rollers arranged according to the vertices d '' a deformable parallelogram, two vertices of which are fixed and the other two are mobile but maintained at a distance determined by a spacer, the displacement of movable vertices taking place as a function of the pressure exerted by the strip on the stack in formation, permanently measured by a stress sensor acting on the movement control of the carriage, parallel
  • the mobile carriage carrying the stacking head is driven by a toothed belt meshing with a pinion controlled by a gearmotor, so that the rotation of this pinion as the stack is formed determines a movement in the opposite direction of the carriage.
  • the spacer now at a given distance the two movable rollers of the parallelogram, these have their axes secured to a support guided in a displacement groove provided in the chassis of the movable carriage. Also preferably, the support of the rollers cooperates with a ball slide, mounted in the displacement groove.
  • a calibrated spring stop is associated with the stress sensor in order to allow, when the pressure on the pile exceeds a given maximum threshold, the displacement of the movable rollers and the disengagement of the carriage the stacking head.
  • a pulse wheel is mounted substantially tangent to the plane of the strip, so that the envelopes cause this wheel to rotate during their movements with the strip, the wheel providing then a train of pulses characterizing the positioning of these envelopes prior to their introduction into the stack for the subsequent control of a possible catch-up mechanism.
  • the reference 1 designates as a whole a device for the formation of a stack of flat objects according to the invention, these objects being in particular constituted by envelopes 2 which, in the example considered, have the same format but which, in variants, could have different dimensions from one to the other within a certain limit, these envelopes further comprising thicknesses and weights which are not necessarily identical from one envelope to the next.
  • the envelopes 2 rest by their edge or lower edge on a horizontal plane support 3 and are jogged laterally on one of their sides by means of a vertical edge 4, the plane of the support and of the edge forming in particular a reference dihedron for stack of envelopes 2.
  • envelopes are conveyed to the device by means of a conveyor assembly 5, conventionally comprising in any mail sorting installation two parallel belts, respectively 6 and 7, capable of pinching the envelopes between them to ensure their displacement in at the same time as the belts, the envelopes being able to be separated or overlap each other from one to the other in so-called tiled formation.
  • a conveyor assembly 5 conventionally comprising in any mail sorting installation two parallel belts, respectively 6 and 7, capable of pinching the envelopes between them to ensure their displacement in at the same time as the belts, the envelopes being able to be separated or overlap each other from one to the other in so-called tiled formation.
  • the belt 6 is guided on rollers or rollers, respectively 8a, 8b, 8c, against which are supported by the strands go 6a then return 6b of this belt.
  • the belt 7 is guided by rollers 9a, 9b, 9c, 9d, with its forward and reverse strands 7a and 7b partially surrounding these rollers according to the path determined by the latter.
  • the most distant rollers, respectively 8b for the belt 6, 9d for the belt 7, are arranged so that each of the envelopes 2 is distributed at the end of the conveyor 5 towards a stacking head 10, the latter being designed so as to drive these envelopes one by one, by positioning them suitably in the dihedral formed by the support 3 and the edge 4.
  • the stacking head 10 is supported by a movable carriage 11 having laterally a flange 12 surrounding the side of the support 3 so that the movement of the carriage can be carried out parallel to the edge of the aforementioned reference dihedron, as and as the stack is formed and in particular variations in thickness thereof.
  • This movement is in particular carried out, in itself known manner, by means of a toothed belt 13, guided on toothed rollers 14, at least one of which is driven by a geared motor 15 carried by the carriage.
  • the carriage 11 extends transversely with respect to the head 10 so as to support the guide rollers of the belts 6 and 7 which thus move with the carriage, the conveyor 5 being provided with means (not shown) permanently allowing the slack in the belts to be taken up according to the position of the carriage.
  • the stack of envelopes 2 is thus formed between the stacking head 10 and a frame 16 schematically represented in FIG. 1, making it possible to extract these envelopes one by one from this stack, either with a given separation between each of the envelopes as illustrated in the drawing, either in regular tiled formation where these envelopes overlap mutually over part of their length, the envelopes being taken up in a discharge conveyor 17 comprising, like the feed conveyor 5 at least two parallel belts 18 and 19 pinching the envelopes together, these belts being guided on rollers d 'parallel axes 20.
  • the frame 16 comprises an appropriate unstacking head whose characteristics are preferably in accordance with those described and represented in patent application N ° 91,040 46 filed on April 3, 1991 in the name of the applicants for "Device one-by-one extraction of flat objects from a stack of such objects, including letter envelopes. "
  • the stacking head 10 is constituted by means of four rollers with parallel axes arranged along the vertices of a rhombus, the rollers 21 and 22 being provided along the long diagonal thereof and the rollers 23 and 24 along the small .
  • the axes of the rollers 21 and 22 are carried by the carriage 11 and therefore immobilized in a relative position relative to the latter, while the axes of the other two rollers 23 and 24 are supported by a spacer 25, which maintains a spacing between these axes determined.
  • FIGS. 2 to 4 illustrate more particularly the structure of the different parts of the device and in particular of the stacking head 10.
  • the head 10 comprises a drive belt 26 stretched over the four rollers 21 to 24, one of the rollers whose axis is carried by the carriage 11, for example the roller 22, comprising a control pinion 27, the rotation of which is caused by means of a return belt 28, itself engaged by means of a clutch (not shown) with a second pinion 29 keyed or otherwise secured to the shaft of a geared motor 30, so that this rotation is synchronized on the speed of introduction of the envelopes 2 at the outlet of the conveyor 5.
  • the belt 26 is made of a material having an appropriate coefficient of friction, relatively high, so that, during its rotation on the rollers 21 to 24, it drives the envelopes 2 as and when they come before it at the outlet of the conveyor 5 between the strands 6a and 7a of the belts 6 and 7, in line with the rollers 8b and 9d as shown in Figure 4 in particular.
  • the axes of the rollers 21 and 22 are arranged so that the envelopes 2 which are placed in the bottom of the reference dihedral make with the band a limited but determined angle.
  • the two rollers 23 and 24, joined by the spacer 25 and arranged in the direction of the small diagonal of the rhombus, the sides of which are delimited by the strip 26, are mounted so that they can slide together parallel to this direction, thanks to a support 31 slidably mounted in a ball slide 32, provided at the lower part of these rollers in the facing surface of the carriage 11.
  • the support 31 also has a lateral extension 33 provided to cooperate with a stop 34 acting on a strain gauge 35, capable of indicating, as a function of its deformation under the thrust of the support 31, the value of the pressure exerted on the stack of envelopes and of acting accordingly on the geared motor 15 carrying out the movement of the carriage.
  • a calibrated spring (not shown) is associated with the stop 34 in order to keep the gauge 35 under stress as long as the pressure on the stack of envelopes does not exceed a determined maximum threshold, corresponding to the limit deformation of the gauge, and allow the latter to escape in the event of overpressure, without damaging it, for example in the event of a jam in the stack or of placing in it an object of excessive thickness.
  • the equipment of the device is completed by means of an optical pulse wheel 36, mounted freely in rotation about an axis 37, provided at the end of a support arm 34, this wheel being mounted approximately tangentially. to a lateral plane of the rhombus delimited by the drive band 26, and driven in permanent rotation by the latter so as to provide trains of pulses making it possible to measure the positioning of the envelopes with respect to a given reference, in particular in order to control by means of this information the control of the unstacking head provided in the frame 16 opposite the stacking head 10 and to act in particular on a possible catch-up mechanism.
  • the proposed device therefore makes it possible to thus continuously carry out the measurement of the pressure of the stack of envelopes on the stacking head, such information being essential for the precise control of the movements of the mobile carriage.
  • the regulation of this pressure is adjusted, so that it ensures both the maintenance of the stack and the preservation of a minimum adhesion of each envelope with respect to the drive belt, without interfering with any moment its insertion into it.
  • the extensometric pressure sensor is adapted to provide very precise values, even for a small deformation thereof, thereby making it possible to keep practically constant the angle with which the envelopes are introduced into the head. stacking, this angle constituting an essential parameter for the constitution and the maintenance of the stack, whatever the format, thickness and weight of the treated envelopes.
