Definitions
- the present invention relates to a method for sorting waste mixtures by irradiating the waste objects with electromagnetic and / or acoustic waves, recording the waves arriving from the irradiated waste object in a signal processing device for identifying the waste objects and forwarding signals from the signal server ⁇ processing device to a separation device that sorts out the identified waste object.
- This collection produces a mixture of materials such as foils, cups, bottles and foams made of plastic, cardboard packaging made of composite materials for liquid foods and metal packaging materials, for example made of tinplate and aluminum.
- a well-known example from the prior art is the AKW process, according to which heavy plastics such as polystyrene and polyvinyl chloride in hydrocyclones are separated from the light fraction consisting of polyethylene and polypropylene (AKW-Apparat + Maschinen GmbH, Georg-Schiffer- Straße 70, 8452 Hirschau).
- the applicant has now surprisingly succeeded in reliably and economically carrying out the separation of individual waste components or waste objects using a method, characterized in that characteristic features of the waste objects are detected by irradiating them with electromagnetic and / or acoustic waves, the waste objects using a Processing of the waves arriving from the waste object can be identified by electronic signal processing and, via the electronic signal processing, signals are sent to a separating device which sorts out the identified waste object from the waste mixture and by a device for sorting mixed waste, characterized in that that it contains a radiation source for electromagnetic and / or acoustic waves, possibly a device for receiving the waves arriving from the waste object, a signal processing device for identification g of the waste objects and a separation device controlled by the signals from the signal processing device for sorting out the identified waste objects or in the case of visible light, characterized in that this optionally contains a device for receiving the waves arriving from the waste object, a signal processing device for identifying the waste objects by processing the waves arriving from the waste object or by the device for receiving the waves arriving from the
- the object is achieved in that at least one or more characteristic features of a waste object are detected by the method and the device according to the invention are and these are evaluated in such a way that the identification of the waste object is possible, after which a separation device is started which sorts out the identified object.
- Such features can be the outer shape of the object, such as. B. bottle, cup, tube, cubic and other shapes as well as characteristic lettering attached to the object, product names, company or manufacturer names, trademarks, colors and the like.
- the electronic signal processing is not only able to identify and sort waste objects according to the mentioned characteristics but it is additionally able to evaluate the characteristics based on stored data in such a way that an assignment to the material forming the waste object is possible , for example from a cup shape, possibly with other features, such as the manufacturer's name and the product name, to determine that it is an object made of polystyrene.
- the signal processing device After identification has taken place, the signal processing device forwards the information to a separating device, which brings about the sorting out of the identified object.
- the waste object must first be exposed to radiation with electromagnetic waves or sound waves or to both types of waves.
- the waves reflected from or penetrating the waste object are picked up by the electronic signal processing device or initially by an upstream device such.
- an upstream device such.
- the waves used to identify the waste object are generally or predominantly reflected rays that occur during irradiation or those that first penetrated the object. Of less importance are those waves that arise from a secondary radiation, such as. B. heat rays that an initially heated object then sends out as an IR radiation transmitter.
- the entire electromagnetic spectrum can be used according to the invention, as can all acoustic waves. Visible light, IR rays, UV rays and sound waves are preferred.
- the separating device can sort out the identified waste objects from the waste mixture in any way.
- mechanical or pneumatic removal devices are preferably used.
- an air jet can be used to remove the waste object from a moving belt, the object being directed in a specific direction.
- waste mixture is distributed sufficiently. This can preferably be done on a moving conveyor belt or rotating plate, but other devices according to the prior art can also be used.
- An arrangement according to the invention is shown by way of example in the figure. 1) represents the conveyor belt, 2) a waste object, 3) is, for example, a video camera, 4) a signal processing device and 5) a separating device.
