Definitions

  • the present invention relates to a high throughput sorting system. It finds an application in the sorting of isolated loads, in particular postal sorting.
  • An isolated load sorting system includes a conveyor composed of a series of object carriers (eg buckets or trays), which can dump their contents into selected receptacles.
  • object carriers eg buckets or trays
  • Two types of conveyors are generally used: straight line conveyors, with receptacles on each side, but whose return strand is not used for sorting, and closed-loop conveyors, also known as carousels .
  • the conveyor Whatever the shape of the conveyor, it is supplied by one or more loading devices, also called injectors, which receive the objects to be sorted by a transport path which guides the flow of objects.
  • loading devices also called injectors
  • the object of the invention is precisely to propose a sorting system having a high throughput while using a relatively slow conveyor.
  • the objects instead of directing the entire flow of objects to be sorted on an injector and then effecting the distribution in the various receptacles situated along the conveyor, the objects are sorted according to the invention according to their nature and their destination to direct them to different injectors, so that the locations that appear to the right of the injectors are available to the maximum.
  • This optimization is obtained by adjusting the partial flows obtained after the preliminary sorting and according to the particular characteristics of the sorting system used, as will be seen more clearly below with the aid of examples.
  • the document FR-A-2 387 697 describes a sorting installation which comprises a conveyor along which are arranged groups of receptacles and loading stations.
  • the loading stations receive objects which have not been sorted beforehand, that is to say intended, as a whole, for all the receptacles, the probability that the objects go here or there being the same for the four stations. .
  • there is a pre-sorting device which supplies the injectors in articles intended only for the following receptacle.
  • the invention therefore relates to a sorting system of high-speed objects comprising a conveyor along which are arranged groups of receptacles capable of receiving some of the objects carried by the conveyor, at least two loading devices of this conveyor, these devices being supplied with objects to be sorted by an arrival path, characterized in that the arrival path of the objects to be sorted is provided with a pre-sorting device which feeds several partial paths each leading to a conveyor loading device, this pre-sorting being such that the objects transported by each partial path are completely discharged into the receptacles arranged between the loading device supplied by this path and the device disposed directly downstream relative to the movement of the conveyor.
  • the objects transported by the path 11 are directed to an injector I 11 which loads the conveyor 5 at this location and which is followed, downstream, by a group P of
  • the objects transported by the path 12 are directed to a second injector I 12 which loads the conveyor upstream of a group of receptacles R.
  • the efficiency of a system like the one in figure 1 is an increasing function of the probability lity, for an injector, to find before him a free object holder on the carousel. The best performance is obtained if all the test objects presented in front of an injector are free.
  • An injector can load at most C objects per unit of time. The following two relationships must therefore be satisfied:
  • the throughput of the sorting system has therefore been doubled thanks to the arrangement adopted.
  • the system of FIG. 2 represents, for example, a sorting system with two arrival lanes each provided with a pre-sorting device.
  • the first, of flow F 1 has the same references as in FIG. 1 (with however a partial flow noted (r 1 + r 2 ) F 1 on the path 12).
  • the operation of this system is as follows.
  • the flow pF 1 which passes through the path 11 is discharged into the group P which follows the injector I 11 .
  • the flow (r 1 + r 2 ) F 1 which passes through the path 12 is partially discharged (r 1 F 1 ) in the group R 1 , the remaining part (r 2 F 1 ) passing in front of the injectors I 21 and I 22 and discharging into the group R 2 which follows.
  • the partial flow pF 2 which passes through the path 21 discharges into the group P, which immediately follows the injector I21 .
  • the flow which passes through the path 22 is partly discharged (r2F2) in the group R 2 .
  • the remaining part (r l F 2 ) passes in front of the injectors I 11 and I 12 and is discharged into the group R 1 which follows.
  • the parts p F 1 and p F 2 are routed to the injectors I 11 and I 21 .
  • the parts r 1 F 2 and r 2 F 1 represent the fraction of the object carriers occupied immediately before, respectively, the injectors I 11 and I 12 , and the injectors I 21 and I 22 .
  • FIG. 3 The configuration of FIG. 3 is precisely intended to ensure that each injector finds in front of it all the free object carriers. This result is obtained by practicing on all the objects a sorting in three separations, giving rise to three partial paths 11, 12 and 13 for the first arrival path and 21, 22, 23 for the second.
  • a grouping device 31 joins the paths 13 and 23 in a single path 32 directed towards an injector 132.
  • a grouping device 33 joins the paths 12 and 22 in a single path 34 directed towards an injector I 34 .
  • the operation of the device of Figure 3 is as follows. On the F 1 objects taking the path 10, pF 1 are directed to I 11 , r 1 F 1 to I 34 and r 2 F 1 to I 32 . The same operation is done on the F 2 objects taking path 20.
  • the injector I 34 ultimately, processes r 1 (F 1 + F 2 ) objects, and the injector I 32 , r 2 (F 1 + F 2 ) objects.
  • the arrival path 10 is separated into three partial paths 11, 12 and 13 leading to three injectors I 11 , I 12 and I 13 with flows pF 1 , qF 1 and rF 1 .
  • Each injector receives the fraction of the flow which must be discharged between this injector and that which is arranged immediately downstream, in the direction of movement of the conveyor.
