Definitions

  • the invention relates to a device for sorting out flat objects that are too high according to the preamble of claim 1.
  • the objects that are too high are sorted out as follows:
  • the disordered flat objects reach a transport path, from which objects that are too high are separated out with a first extractor and reach a first straightening path with a base belt via a slide, the direction of movement of which coincides with that of the transport path.
  • the straightening function is realized with stops at a certain height, against which upright objects are transported and thus tilted onto their long edges.
  • the stream of objects is fanned out with a first fan and then with a second extractor, which detects the objects that are too high compared to the first extractor at a somewhat lower height and also transports them to the first straightening section, further sorting with subsequent other fans with a second fan.
  • a third extractor is arranged, which still separates objects that are too high and conveys them to a second straightening section parallel and opposite to the first straightening section.
  • the objects not detected by the first two extractors are passed via a switch, a deflection and a junction to a third straightening section, which is re-introduced into the transport path via a further deflection in front of the first extractor.
  • This third straightening section is also connected to the first straightening section via a deflection and the merging.
  • a fourth extractor located at the end of the second straightening section discharges the objects, which are still too high, into a collecting container.
  • the remaining objects leaving the second straightening section also reach the transport path before the first extractor via a deflection.
  • a disadvantage here is the many deflections in which the objects are subjected to severe bending stresses that could lead to damage.
  • a further disadvantage is that the objects which are only separated out via the first three extractors are integrated into the new stream of objects before the first extractor and have to go through the extraction and fanning out stages again. This reduces the throughput and can lead to new upright positions, for example when fanning out. Furthermore, this solution takes up a relatively large amount of space.
  • the invention is therefore based on the object of a device for sorting out to create high flat objects with little space requirement, during which passing through several extraction stages due to an upright position, but at the end of the multi-stage extraction procedure back to normal tipped shipments do not have to go through the extraction stages again.
  • the object is achieved by the features of claim 1.
  • the advantage here is that the objects separated from the first extractor from the transport channel never pass this extractor a second time and only one redirection is necessary.
  • the areas of the secondary channels on which the separated objects slide are inclined to the horizontal in the transport direction.
  • the combination: direction of slide of the objects, transport direction of the secondary channel and inclination of the relevant secondary channel section triggers a tilting movement of the objects into the flat edge position.
  • the transport channel or the diversion can be passed under these secondary channel sections, thereby reducing the space required.
  • a fanning out device 6 is located in front of the sorting device.
  • Here is part of a lateral guide of a transport channel with an underfloor belt as Conveyor belt driven and driven. Loom on the other side elastic tongues with appropriate coefficients of friction in the channel on which Shipments are slowed down while possibly consignments located next to it are transported further by the side belt become, i.e. adjacent consignments are fanned out.
  • the consignments in transport channel 1 reach the first extraction stage, consisting of an extractor 2 and a slide 5. Between two bands, the are guided diagonally upwards over rollers and resiliently rest against each other, where only one belt is driven by an electric motor, become too high Shipments are pinched, pulled out and onto the corresponding slide 5 hurled.
  • the consignments not covered by the first extraction stage are sent by the Transport channel 1 via a first junction 3 with a wide underfloor belt transported to the deflection 4.
  • the deflection 4 consists of semicircular arranged rollers, on the outside of which a driven endless Volume 4.1 is excited. On this band 4.1 runs a lot on the roles stretchable shroud 4.2. The one to be transported is between the two belts Parcel jammed and along the rollers to the second part of the Transport channel 1 out. Due to the strong elasticity of the shroud 4.2 are the bending stresses of the shipments during the redirection kept low. Then the shipments are of the desired size a further merge 3 fed to the subsequent processing.
  • junction 3 also opens the first secondary channel 7, so that the overturned upright items or normal items entrained during extraction can leave the device for sorting.
  • a second extraction stage also consisting of an extractor 2 and a slide 5.
  • the extracted here Shipments reach the inclined part 8.1 via the slide 5 a second secondary channel 8, which is approximately parallel to the first secondary channel 7 runs and opens into the first merging 3 before the deflection 4.
  • This second secondary channel 8 is a third extraction stage, consisting of from an extractor 2, a slide and an underfloor belt, with which the large consignments are transported to a storage compartment.
  • the programs with the Desired size are after the first extraction stage and before Redirection 4 introduced into the stream of mail again, so that not too large consignments do not go through the extraction procedure a second time have to. Due to the inclinations of the secondary channels 7, 8 on the slides 5, it is possible to route the shipments below these areas, whereby the required space can be reduced.
