Definitions

  • the invention relates to a device for classifying lumpy, oblong-shaped products according to the preamble of the main claim.
  • a generic device is described in DE-OS 34 27 535 and it is based on the task of creating a length sorting that has a high delivery rate.
  • the present invention has for its object to improve the device working with a sorting wheel according to DE-OS 34 27 535 in such a way that an even more secure definition of the products to be measured and thus a significantly higher delivery rate can be achieved.
  • the product to be measured is held securely by a vacuum acting on the product in the area of the measuring station and can thus be scanned in a flawless manner by the measuring device.
  • the product which does not correspond to the actual length, is ejected in the vacuum-free area by a compressed air jet, which is guided from the outside of a wheel disk of the sorting wheel into the interior of the measuring gap and there acts on the outer circumference of the sorting wheel on the product to be ejected.
  • the products corresponding to the actual length then arrive at the ejection station - unaffected by this - from the sorting gap in a corresponding receiving container. Since there is no longer a vacuum on the goods to be sorted in this area, the goods to be sorted, the Istlän ge corresponds to get out of the sorting gap into the receptacle solely by gravity.
  • FIG. 1 denotes a storage container which receives the lumpy sorting goods and has a discharge opening at its lower end, under which oscillating conveying elements are arranged.
  • the sorting goods 1 which are separated in this way and have an oblong shape are then fed to a sorting machine 3 belonging to the prior art, in which the goods 1 to be sorted are sorted according to the outer contour.
  • the goods to be sorted 1 corresponding to the desired values are then fed to a length measuring station 2, which in the embodiment shown in FIG. 1 consists of a sorting wheel 12.
  • the sorting material 1 corresponding to the desired length is fed to a receiving container 21, while the sorting material not corresponding to the desired length is ejected in the region of the sorting wheel by a throwing device 14 (FIG. 2) and is fed to a corresponding receiving container 20.
  • a throwing device 14 denotes a scanning device which works with a beam 5, such measuring devices being known, for example, as so-called reflection scanners.
  • Fig. 2 shows the design of the sorting wheel 12 and the facilities required for measuring and ejecting.
  • the two wheel disks 22 and 23 each have a stepped shoulder 25 or 26, the stepped shoulder 25 of the wheel disk 23 projecting below the step 26 of the wheel disk 22.
  • the stepped surface of the stepped shoulder 25 thus formed is designed as a reflection surface 27. At 4 the reflection button can be seen, the rays 5 of which are reflected by the reflection surface 27 and which, depending on the signals obtained in this way, generates pulses for ejecting the sorting material 1 which does not correspond to the desired length.
  • wheel disks 22 and 23 are adjustable relative to one another enables the sorting gap 11 to be adapted to different thicknesses of the items 1 to be sorted.
  • a vacuum chamber 28 adjoins the wheel disk 22, which lies sealingly (at 29) on the outside of the wheel disk 22.
  • the vacuum chamber 28 is above a lei device 34 with a vacuum source, not shown, in connection.
  • a vacuum line 31 opens towards the sorting gap, which opens at such a height within the sorting gap 11 that the vacuum line 31 opens in the sorting gap 11 when a product 1 is in contact this material 1 exerts a vacuum suction and thereby holds the material 1 in the sorting gap 11.
  • compressed air lines 32 open below the goods to be sorted which are held in the sorting gap 11 and connect to a compressed air source (not shown in the drawing) of the ejection device 14, the direction of the compressed air flow being indicated by the arrow DF .
  • the compressed air line 32 which essentially leads through the wheel disk 23 in the axial direction, is angled upward within the wheel disk 23 and thus opens within the sorting gap 11 toward the outer circumference of the sorting wheel 12 under the item 1 to be sorted. The angle is selected so that that the full flow of compressed air directed towards the outer circumference of the sorting wheel 12 opens into the sorting gap 11.
  • the vacuum line 31 opening into the interior of the sorting gap not only causes the sorting material 1 to be held in the sorting gap 11, but at the same time also causes suction particles of the particles to be sorted which are deposited on the reflection surface 27, so that the arrangement of the Vacuum connection fulfills two functions, namely a secure fixing of the sorted goods 1 in the gap and an automatic and constant cleaning of the reflection surface 27.
  • the sorting goods 1 that have been placed in the sorting wheel 12 and have an oblong shape reach the sorting gap 11 through the pre-sorting gap 24 and are fixed here under the effect of the vacuum of the vacuum chamber 28.
  • the reflection button of the scanning device 4 now detects the length via its rays 5 reflected on the reflection surface 27 or not reflected by the material 1 to be sorted, and this scanning device 4 now controls the operation of the compressed air nozzles as a function of the set measurement values.
  • the compressed air nozzles are switched on and the compressed air jet flowing through the compressed air line 32 causes the sorted material 1 to be ejected, which is no longer under the action of the vacuum chamber 28 in the region of the ejection station 14.
  • the material corresponding to the desired length passes beyond the ejection device 14 as seen in the direction of rotation of the sorting wheel 12 and can be released into the receiving container 21, for example solely due to gravity, since in this area vacuum suction no longer acts on the material to be sorted, i.e. the goods to be sorted can simply fall out of the sorting gap 11.
