Definitions
- the invention relates to a device for sorting out excessively high flat objects according to the preamble of the first claim.
- the objects that are too high are sorted out as follows.
- the disordered flat objects arrive on a transport path, from which objects that are too high are removed and a slide leads to a first straightening section arrive with a base belt, the direction of movement of which coincides with that of the transport path.
- the straightening function is realized with stops at a certain height, transported against the upright objects and thus tilted onto their long edges. After the first extractor, the flow of the objects with a first
- 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, with a further fanning out with a second fanning out.
- 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 led via a switch, a deflection and a junction to a narrow straightening section, which is reintroduced into the transport path via a further deflection in front of the first extractor.
- the third straightening section is also connected to this third straightening section by means of a redirection 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 first extractor into the transport path.
- the disadvantage here is the many deflections in which the objects are subjected to strong bending stresses, which could lead to damage.
- a further disadvantage is that the only three extractors discarded items before the first extractor are incorporated into the new stream of items and have to go through the extraction and broaching stages again. This reduces the throughput and can lead to new upright positions when fanning out, for example. Furthermore, this solution takes up a relatively large amount of space.
- the invention is therefore based on the object of providing a device for rejecting flat objects which are too high, in which objects which have been separated out but are not too high in extraction stages are not subjected to any further extraction, the mechanical stress on the objects is as low as possible and a small space requirement is possible.
- 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.
- FIG. 1a shows a side view of a device for sorting out fiat from a mail flow.
- FIG. 1b shows a corresponding top view.
- part of a lateral guidance of a transport channel with an underfloor belt is designed as a belt guided and driven by rollers.
- elastic tongues with corresponding coefficients of friction protrude into the channel, on which items are braked, while possibly consignments located next to it are transported further by the side belt, ie consignments lying next to one another are fanned out.
- the mail items in the transport channel 1 reach the first extraction stage, consisting of an extractor 2 and a slide 5.
- the first extraction stage consisting of an extractor 2 and a slide 5.
- the consignment that is too high arrives at the inclined part 7.1 of the first secondary channel 7.
- upright and thus unintentionally separated consignments can tip over to their long side, i.e. they are forwarded as machine-readable consignments for subsequent processing, since they are extracted by the subsequent extractors 2 can no longer be detected.
- the mail items not recorded by the first extraction stage are transported by the transport channel 1 via a first junction 3 with a wide sub-band to the deflection 4.
- the deflection 4 consists of semicircularly arranged rollers, on the outside of which a driven endless belt 4.1 is stretched.
- a very stretchable shroud 4.2 runs on the rollers 4.1 on the rollers. The consignment to be transported is clamped between the two belts and along the rollers to the second part of the
- the first secondary duct 7 also opens into this junction 3, so that the upturned upright mail items or normal mail items entrained during extraction can leave the device for sorting out.
- the items which are extracted here pass via the slide 5 to the inclined part 8.1 of a second secondary channel 8, which is approximately runs parallel to the first secondary duct 7 and opens into the first union 3 before the deflection 4.
- this second secondary channel 8 there is a third extraction stage, consisting of an extractor 2, a slide and an underfloor belt, with which the oversized items are conveyed into a storage compartment.
- the consignments of the desired size are thus re-introduced into the consignment stream after the first extraction stage and before the deflection 4, so that the consignments that are not too large do not have to go through the extraction procedure a second time. Due to the inclinations of the secondary channels 7, 8 on the slides 5, it is possible to route the shipments below these areas, which can reduce the space required
