Definitions

  • the present invention is in the field of processing flat objects, in particular postal sorting. It relates more particularly to the separation of different plies having variable physical characteristics between them in a very wide spectrum which leaves the range of the so-called mechanizable mail processed in existing sorting machines.
  • Such non-mechanizable mail is for example composed of thick letters, simple response cards, magazines put under address tape or under protective plastic coating, packets of letters for the same destination, or folds of other kinds. It is generally presented in bulk or in poorly organized piles in boxes or baskets.
  • the documents DE-B 1155 716 and DE-B 1198 283 describe another type of installation for separating folds which occurs in bulk, using a suction suction head.
  • a device for scanning an area of the surface for receiving bulk plies ensures the examination of this area and makes it possible to control the suction head for its precise positioning on a single ply then removed and transferred.
  • the suction head has multiple orifices and is mounted at the end of a gripping arm with two articulations independent of one another.
  • the suction head comes to be applied on two adjacent or overlapping plies, these are taken at the same time, they are however distributed one after the other by rotation of the head which presents them. one after the other in front of the exit conveyor.
  • the object of the present invention is to produce a separator of flat but characteristic objects which remain disparate, of the type with suction head at the end of a gripping arm, which avoids a double articulation with independent control on the arm or precise positioning of the head on a single object then removed.
  • the separator comprising an entry station for a stack of said objects, an exit conveyor for said separate objects, and a station transfer powered from the input station, coupled to the output conveyor and comprising at least one suction head disposed at the end of a gripping arm itself driven on a fixed path and the suction head being provided with multiple orifices which are open on a gripping face and coupled to a suction source and ensure the removal of objects, characterized in that the separator further comprises a blowing source coupled to said orifices in the head, means individual selective communication of each orifice with one or the other of said sources of suction and blowing, a device for taking an image of the instant scene year at the transfer station and an image processing device associated with the image pickup device ensuring the recognition of a take to be made by the head, and controlling said individual means for the depression of only the orifices of the head which are internal to the recognized outlet and the simultaneous overpressure of the other
  • the broad spectrum mail separator according to the invention is intended to ensure the processing of mail whose individual folds have physical characteristics, such as format, weight, rigidity, packaging, etc., which are very disparate, varying in a very broad spectrum. and leaving the range of so-called mechanizable mail processed in existing high-speed sorting machines.
  • Figure 1 there is illustrated such a broad spectrum mail separator, operating from a poorly organized mail stack.
  • It has an input station 1, consisting of an end part of a storage magazine 2 of a stack of plies 3, and an output conveyor 4, intended to drive the individual plies from magazine 2.
  • magazine 2 the folds are arranged on edge and rest on its bottom.
  • the bottom of this store is substantially horizontal, it is located substantially in the same plane as that of the outlet conveyor 4.
  • the magazine 2 is equipped with push fingers 5.
  • These push fingers are driven in displacement over the length of the magazine, on a closed trajectory defined by an endless chain 7 arranged under the bottom 6 of the store, which are integral with said fingers. They are in a vertical position, in relief on the level of the bottom through a slot 8 for driving the folds along the length of the magazine. They are retracted in the folded position for recycling at the store entrance.
  • the magazine is also equipped with a side wall 10 forming a stop for the approximate alignment of the pleats by one of their edges.
  • a set of rollers 11 is arranged, along the length of the magazine, at its middle part. These rollers are flush with the internal surface of the bottom, through longitudinal slots made in the bottom (not referenced). They are rotated, according to arrow 13, (FIG. 2), by means not shown, to ensure in this middle part of the magazine a jogging of the folds on the side wall 10.
  • the equipment of the magazine 2 as well as the means for putting and holding the fingers in a vertical position in the magazine for driving the folds along the length of the magazine and the means for retracting the fingers at the outlet of the magazine for their recycling, are for example in accordance with the embodiment given in the document FR-A-23 82 387 cited above. This store is therefore not described in more detail in the present application.
  • the folds are inserted in sets between the fingers 5, at the entry station 1. They are driven, up to the opposite end part, or exit 20, of the magazine while being tapped against the side wall 10 in the middle part of the magazine regardless of the position of the folds during their insertion. In the terminal part 20, the folds are practically aligned against the side wall 10.
  • the terminal part 20 is open at the end of the magazine. It is located opposite the conveyor 4, at a distance from it. It constitutes the transfer station for folds from the store to the exit conveyor, this transfer station being designated hereafter by this same reference 20.
  • the fingers 5 retract in this transfer station to allow the removal of the folds and their transfer .
  • This end part 20 is however equipped with means preventing the set of folds pushed by the finger 5 on this part from collapsing at the end of the magazine. These means are illustrated in the form of a simple flange 19 at the end of this terminal part. This rim retains the terminal fold by forming a stop over part of the length of its foot.
  • the separator comprises a gripping arm 21 with a terminal suction head 22, substantially vertical.
  • the suction head 22 is in the so-called rest position, outside the transfer station and the outlet conveyor. In the illustrated embodiment, it is arranged on the side of the magazine, between the transfer station and the outlet conveyor, at the front of the side wall 10 with a slight difference therefrom.
  • This suction head has on its face turned towards the folds, a plurality of orifices ending in the shape of a suction cup 23.
  • These orifices are individually connected to a suction source 24 or to a blowing source 25 by conduits such as the conduit 26.
  • Each of these conduits 26 is selectively controlled, with one of the sources 24 and 25, produced for example by means of a valve 27, of the double channel type.
  • the gripper arm 21 is coupled to a drive motor 30, by means 29 of the rack and pinion type, imparting an alternating translational movement to the arm and therefore to the suction head.
  • This translational movement is illustrated by the double arrow 31. It is transverse to the direction of the folds in the magazine.
  • the suction head is brought from its rest position to a fold gripping position for which it is located in the transfer station, then to a fold transfer position for which it is located substantially at the entry of the exit conveyor. It is then returned to its initial rest position. This operation of the suction head is explained below with reference to FIGS. 3 to 8.
  • a camera 32 takes the image of the scene instant at the transfer station.
  • This camera 32 is coupled to an image processing circuit 33 which recognizes the contour of the terminal fold to be captured and therefore controls the drive motor of the arm and the depression or overpressure of the orifices 23.
  • the recognition of the contour of the terminal fold at the transfer station is carried out by circuit 33 essentially by differential processing of the instantaneous image captured by the camera.
  • the front of the transfer station is for this purpose, advantageously lit by a light source not shown, placed so as to accentuate the shadow effects of the outline of the first terminal fold on the other folds, when this terminal fold is smaller. than the others.
  • a receptacle 35 receives unacceptable folds. These unacceptable folds are, for example, damaged folds; they are also detected by the camera and the processing device. To no longer take it into account in the processing of the folds transferred to the outlet conveyor 4, these unacceptable folds are directly rejected into the receptacle 35.
  • the output conveyor 4 receiving the folds taken by the suction head comprises, at the input, a substantially vertical vacuum belt 40.
  • This belt 40 follows a pair of fine belts 41, 42 ensuring, by pinching between them, the grip and driving the folds they receive from the vacuum belt.
  • the vacuum belt 40 is a belt substantially perforated over its height. It is stretched between three pulleys 44, 45 and 46 of substantially vertical axes and continuously driven along arrow 47 by drive means not shown coupled to at least one of the pulleys. These pulleys are arranged so that one of the strands of the belt, called strand for receiving folds 48, is substantially in the plane of the end fold to be removed from the transfer station. A vacuum box 49, inside the belt, ensures the depression of the strand 48 of the belt 40.
  • this receptacle 50 collects any double sockets made by the suction head 22.
  • a pressure roller 51 conditions their positioning and their maintenance in application against the receiving strand 48 of the vacuum belt, in particular at the start of the return to position. initial of the suction head.
  • This roller is facing the strand 48. It is mounted on the end of a rod 52. It is biased in the detached position of the belt by a spring 53 mounted captive around the rod, acting according to the arrow 54. It is by against controlled, according to the opposite arrow 55, by a control element 56 such as an electromagnet, coupled to the end of the rod opposite to that carrying the roller.
  • This electromagnet is also connected to the processing circuit for its own control.
  • the suction head 22 is in the rest position, between the transfer station 20 and the perforated vacuum belt 40.
  • the camera 32 has taken the image of the scene at the front of the transfer station and transmitted it to the processing circuit 33.
  • This circuit 33 determines the dimensions of the terminal fold 38, in particular its height h. It also determines the distance d from the edge of the fold 38 with respect to the side jogging wall 10, the jogging of this smaller fold having not been perfectly ensured. Consequently, it firstly triggers the control of the motor 30, to bring the head 22 in front of the fold 38.
  • FIG. 8 illustrates this step of returning the head 22 to its rest position, carried out according to arrow 31a. Simultaneously the fold 38 held by the roller 51 against the belt is driven along the arrow 47 by this belt.
  • the pressure roller is released. It then comes under the action of the only recessed spring facing the belt.
  • the fold is moved by sliding the transfer station at the entrance to the exit conveyor.
  • a gateway 16 (FIG. I) between the transfer station and the vacuum belt 40.
  • This gateway is substantially at the same level as the bottom 6 of the magazine and presents facing the head in the rest position.
  • FIG 9 there is illustrated a variant given with reference to Figure 5, with regard to the operation of the separator.
  • the piis 38,39 and following are slightly inclined on the vertical, having at the transfer station their feet more forward than their upper part.
  • the inclination of the folds in the terminal part can be obtained by means, not shown, as such known, for example a suitable air jet or bottom belts of the store in this terminal part, while retaining an arrangement substantially horizontal from the bottom of the store.
  • the suction head 22 as soon as it arrives opposite the fold 38 to be transferred, is actuated according to arrow 57 to pivot on the end of the arm 21 on which it is articulated at 58. The head is thus applied against the fold 38 for its transfer.
  • the drive of the fold 38, by sliding, to the vacuum belt 40 is then done in this inclined position of the head; the vacuum belt 40 and the stop 17 on the gangway 16 (FIG. 1) can have the same inclination as can the conveyors 41, 42.
  • the entire device can be inclined horizontally, upwardly sloping towards the bottom of the magazine towards the transfer station 20 and with the suction head 22, the vacuum belt 40 and the pair of belts 41 and 42 having the same inclination on the vertical.
  • This arrangement eliminates the pivoting movement of the head on the end of his arm for its application against the fold to be transferred.
  • FIG. 10 an alternative embodiment of the mail separator according to the invention is illustrated.
  • the folds 60 are deposited in bulk or in unorganized sets at the entry station of the separator, constituted by an entry ramp 61 followed by an inclined belt 62. On this belt 62, the folds slide one on the others while spreading out.
  • a roller 63 associated with the belt facilitates the spreading of the folds in a single layer.
  • a mat 64 which is substantially horizontal, directly receives the folds coming from the belt 62. It drives them according to arrow 65, it is said to be the main mat.
  • this main belt 64 On sections of this main belt 64 are formed, one after the other, several fold transfer stations, identified at 70 and 71 for the two illustrated stations.
  • Two outlet conveyors, 72 and 73 for the transfer station 70 and 74, 75 for the station 71, are assigned to each fold transfer station.
  • These two output conveyors by transfer station can be independent of each other or constitute the inputs of a common conveyor not shown. They are substantially in the same plane as the main belt 64, being on one side and the other of the transfer station.
  • Each of the fold transfer stations is similarly equipped; this equipment is described with reference to station 70. It has two arms for gripping the folds 76, 77 both driven by an alternating movement of rotation of fixed trajectory, according to the double arrows 78 and 79 for these two arms.
  • One end of each arm such as the arm 77 for example, is offset from the edge of the belt 64 and coupled to a drive shaft 80 itself coupled to a control motor 81.
  • the second end of this arm forms a suction head 82 with several orifices 83 in the form of suction cups, which are open on the side of the belts 64, 73.
  • the terminal suction head 82 has its orifices individually connected by internal conduits to the arm, selectively to a suction source and a blowing source, not illustrated in this FIG. 10, but in accordance with those of FIG. 1. These suction and blowing sources put the orifices in depression or overpressure to retain a fold by "sticking" against the head.

  • the arm 76 equipping this transfer station 70, and the arms equipping the other transfer station 71 are identical to the arm 77. They are therefore not described individually below, their operation is also identical to that of the arm 77.
  • a camera takes the image of the scene instantaneous at the front of the transfer station, the camera is located at 84 for the transfer station 70.
  • the image taken relates to the two gripping arms of the station.
  • An image processing circuit 85 coupled to the camera ensures the analysis of the image taken and the recognition of the folds arriving at the transfer station 70 and which may concern one or the other of the arms at times of encounter between each of these folds and each of its heads.
  • the outlet conveyors, 72 and 73 or 74 and 75, assigned to each of the transfer stations allow a gap to exist between them and the main belt 64 on each side of the belt. This interval is normally closed by a hatch 86 or 87, depending on the side considered. These hatches are slightly below the level of the belt 64 and the outlet conveyors. They collect possible double sockets or possible unacceptable folds seized by the suction heads. In the intervals between the main belt 64 and the outlet conveyors, two fold recycling belts 90, 91 are arranged. These belts are located under the hatches.
  • the doors are pivotable in one direction or the other, around an axis such as the axis identified at 97 on one of the doors 86. Pivoting in the direction given by arrow 98 indicated on one of the hatches 86, they drop the folds they collect on the recycling belt. Pivoting in the opposite direction, shown by arrow 99 on one of the hatches 87, they drop the folds they collect on the associated ejection ramp.
  • the corresponding command for segregation between folds to be transferred to the output conveyors and those said to be unacceptable is given by the processing circuit from the image taken by the camera. This command is transmitted to an actuating motor for each of the doors, not shown to avoid excessive overloads in this figure. This command also cuts off the connections between the suction source and the orifices so that the unacceptable folds are released on the hatches.
