Definitions

  • the present invention relates to a device for sorting waste according to the preamble of claim 1.
  • DE 195 45 240 A1 discloses a device for separating material mixtures by type, with which plastic parts or also aluminum parts can be sorted. Since the plastic parts to be sorted have very different sizes, a mill is provided which breaks the plastic parts down to a certain maximum size. A sieve device is connected to the mill, in which fine fractions are separated. The plastic parts then go to a first vibration conveyor, which feeds them individually to a rolling mill consisting of two rollers. The plastic parts are smoothed in the rolling mill. Another vibration conveyor conveys the parts to a sorting carousel, transport switches being arranged at the end of the vibration conveyor which guide the parts transported by the vibration conveyor into several transport tracks.
  • the sorting carousel is equipped with a larger number of gripping arms, a certain number of gripping arms being assigned to a transport path.
  • the gripper tongs grip at the end of the second vibration conveyor the plastic parts from the respective webs.
  • the parts gripped by the gripper arms reach a measuring head, which is used to determine the type of plastic in conjunction with a controller.
  • the gripper arms are then controlled in such a way that they drop the identified plastic parts over a respectively assigned ejection chute, which leads into a collecting container.
  • DE 42 17 481 A1 describes a method and a device for sorting waste mixtures, in particular waste mixtures collected in fast food chains, which predominantly contain disposable packaging.
  • waste mixtures in particular waste mixtures collected in fast food chains, which predominantly contain disposable packaging.
  • the disposable packaging supplied to the device together with further waste initially passes through a sieve arrangement in which the further waste is separated off as residual waste.
  • the selected single-use packaging then goes through a material separation stage, which is not explained in more detail. This stage is provided when there is a large amount of aggregated material.
  • the individual disposable packaging then runs into a vibrating sorter, in which a sorting according to the body shape takes place, namely into a lumpy heavy fraction and a flatly light fraction. To the lumpy heavy fraction include z. B.
  • the flat, light fraction essentially contains foils, paper, plastic dishes, cardboard and styrofoam.
  • the latter fraction passes into a suction device, in which films and paper in particular are separated from the lighter fraction.
  • the rest of the lighter fraction is then subjected to sieve classification and vibratory sorting in order to select the other constituents.
  • a generic device is disclosed in DE 197 51 862 A1.
  • This device consists of a plurality of conveyor belt sections arranged one behind the other, a narrow blow nozzle bar being arranged between the conveyor belt sections and extending over the entire width of the conveyor belts. A large number of blow nozzle openings are provided in the blow nozzle bar.
  • the first conveyor belt section is assigned an analysis device, consisting of a color camera, an NIR spectrometer with an NIR sensor and an optical scanning head, these units being controlled by a computer.
  • the output data of the color camera and the output data of the NIR units are evaluated in the computer.
  • the waste conveyed on the conveyor belt section can be recorded in terms of shape, size and its material properties.
  • the waste After the waste has been located and identified on the first conveyor belt section, it reaches the subsequent blow-off nozzle bar after leaving the first conveyor belt section.
  • the subsequent blow-off nozzle bar By activating corresponding blow-off nozzle openings of this blow-off nozzle strip, waste belonging to a material group is blown into collecting devices arranged on the side of the conveyor belt, from which it is discharged via a slide or the like.
  • blow-off nozzle strips are relatively narrow, so that they do not hinder further transport of the remaining waste onto the subsequent conveyor belt section.
  • a further color camera is arranged over this conveyor belt section, which detects the current position of the waste on this conveyor belt section.
  • a renewed NIR spectroscopy is not necessary, since those obtained in the previous stage and saved in the computer NIR values can be used and used for a further cut.
  • This separating cut is made at the end of the second conveyor belt section by a further blow nozzle bar which corresponds to the blow nozzle bar arranged between the first and second conveyor belt section.
  • further separation stages constructed analogously to the second conveyor belt section and the associated devices can follow.
  • the object of the present invention is to provide a device for sorting waste of the generic type which is suitable for waste separation at the point of origin, in particular in fast food restaurants.
  • the device according to the invention manages with a few components arranged one above the other and the components as such do not have a very high construction, the device has a very compact structure so that it takes up little space can be built on site, especially in fast food restaurants. Due to the small space requirement, retrofitting is also possible without any problems.
  • the device is suitable both for manual loading and for integration into a device for emptying and cleaning trays in fast food restaurants, as claimed in a parallel patent application.
  • manual loading of the device e.g. B. in a high-speed restaurant
  • the tray content is entered into the hopper, the paper sheet placed on this to avoid contamination of the tray is previously removed manually.
  • the hopper is designed so that it can hold the contents of several trays.
  • the separating roller arrangement arranged below the hopper ensures that the contents of the hopper are fed to the sorting plate in individual pieces, so that these can be recognized by the video camera and blown through the associated blowing nozzles into the collecting containers provided for these individual pieces.
  • the hopper 1 of the device is dimensioned so that it can hold the content of several trays.
  • a separation roller arrangement 2 is provided at the outlet of the hopper 1. This consists of an upper pair of rollers 3 and a lower pair of rollers 4.
  • the rollers 5 of the upper pair of rollers 3 are equipped with essentially rigid vanes 6, which, as viewed over the length of the rollers 5, are each in a row step-like and with no or only a small longitudinal distance offset from one another and arranged on the circumference of the rollers 5 in a plurality of parallel rows.
  • the distance between the two rollers 5 of the upper pair of rollers 3 is selected so that it is slightly larger than twice the radial extent of the blades 6.
  • the rollers 5 are driven in opposite directions and are adjusted to one another so that the blades 6 of a step in each
  • the nip of the pair of rollers 3 are opposite in the center, as can be seen in FIG. 1.
  • a type of lock staircase is built up one after the other, through which the tray content entered into the hopper 1 successively falls into the roller gap formed between the rollers 7 and 8 of the lower pair of rollers 4.
  • the nip of the pair of rollers 4 is chosen smaller than the nip of the pair of rollers 3, so that large-volume tray content, such as. B. drinking cups and bowls are pressed a little flat in this gap, which leads to a reduction in volume.
  • the roller 7 is a rubberized smooth roller, while the roller 8 is equipped with flexible rubber blades 9. These rubber blades 9 are arranged helically on the roller 8. In their radial extension they essentially cover the nip between the two rollers 7 and 8 and have a high static friction.
  • the roller 7 rotates approximately at the speed of the upper pair of rollers 3, while the roller 8 rotates faster. Both rollers 7, 8 are also driven in opposite directions. Due to the helical arrangement of the blades 9 on the roller 8, only one blade 9 works with the rubberized smooth roller 7.
  • the pair of rollers 4 serves to further separate the contents of the tray, in particular when two articles adhering to one another pass through the nip between the upper pair of rollers 3. Due to the different rotational speeds of the two rollers 7 and 8 and the high static friction of the rubber wings 9, tray contents adhering to one another are separated from one another.
  • a roller 5, 7 and 8 of the two pairs of rollers 3 and 4 is each pivotally suspended so that non-deformable objects that enter the nips can pass through them or can pass without damaging the rollers 5, 7 and 8.
  • the tray contents arrive essentially in individual pieces on a sorting plate 10 arranged below the separating roller arrangement 2.
  • This is slightly funnel-shaped and has a hole 11 at its lowest point for draining of liquid.
  • the wave troughs or crests 12 extending from its edge to the central hole 11.
  • the sorting plate 10 is provided with a non-stick coating to avoid or reduce buildup.
  • three blowing nozzles 13 are provided on the circumference of the sorting plate 10, the blowing direction of which is directed towards the center of the sorting plate 10.
  • a catch basket 14 made of air-permeable, for. B. sieve-like material, under which there is a collecting container 15.
  • the blow nozzles 13 are each connected to a compressed air line 17 via an electromagnetic valve 16.
  • Capacitive sensors 18, which are suitable for detecting food residues, are located below the sorting plate 10.
  • a video camera 19 is arranged above the sorting plate 10. This includes a bright lighting unit, not shown.
  • a control computer which has an input for the signal of the video camera 19, inputs for the sensors 18, at least one output for controlling the roller pairs 3 and 4, a plurality of outputs for controlling the electromagnetic valves 16 and suitable hardware and software Editing image information.
  • the contents of the tray are divided into sorting groups, with each sorting group being assigned a specific blowing nozzle 13 with the collecting basket 14 and collecting container 15 opposite each other. Objects that cannot be assigned to the specified sort groups are treated like another sort group. This also applies to leftovers.
  • the control computer recognizes this via the video camera 19 and immediately stops the drive of the roller pairs 3 and 4. This ensures that only one object lies on the sorting plate 10 at a time. This is identified using the software and assigned to a sort group. The control computer then controls the solenoid valve 16 of the blowing nozzle 13 assigned to this sorting group.
  • the object that has fallen onto the sorting plate 10, eg. B. a cardboard tray, is then blown through the associated blowing nozzle 13 from the sorting plate 10 into the associated basket 14, from which it falls under the force of gravity into the collecting container 15 arranged below.
