Definitions

  • the invention relates to a method for sorting a material flow of a sorting system, as well as a device for sorting a material flow of a sorting system.
  • bottles like other packaging, are disposed of together with other packaging waste or recyclable materials.
  • bottles can be disposed of using the "Green Dot” or "Yellow Bag” recycling scheme, at sorting stations, or at recycling centers or construction sites. Similar sorting and collection systems for household waste, both deposit-based and non-deposit-based, exist in other countries. However, it is also possible for the bottles to be disposed of directly with residual waste.
  • the object of the present invention is therefore to provide a method which enables efficient recycling of bottles made of pulp material.
  • the sorting system can, in particular, be a sorting system for waste or recyclable materials.
  • the sorting system can, in particular, be part of a recycling plant for beverage containers.
  • the material flow can, in particular, be a mixed material flow, which is understood to mean a material flow that contains various types of material.
  • a mixed material flow can include plastic parts, paper parts, pulp parts, metal parts, etc.
  • the term "pulp container” refers here and below to a container made of pulp. However, it is possible for a pulp container to comprise other materials, for example, for a coating.
  • the pulp may comprise fibers, in particular fibers of natural origin.
  • the fibers may contain lignin and/or quinine.
  • the fibers may comprise, for example, cellulose fibers, fibers from conifers, deciduous trees and/or plane trees and/or grasses, reeds and/or bamboo, or the like.
  • the fibers may comprise silk threads, spider threads, algae, natural fibers (such as Danube silphium fibers, hemp, corn, cotton), banana peels, banana leaves, orange peels, grass, straw, potato starch, or processed cow dung.
  • Pulp fibers originating from a process through which they were artificially cultivated may also be provided. These alternative materials can fully or partially replace wood as a raw material for a fluid mass containing fibers in cases of material shortages.
  • the fibers can include fiber blends of non-wood materials, such as cotton, hemp, and/or textile fibers.
  • Recycling is understood in particular to mean the reuse or further use of the material.
  • Thermal recovery is not considered recycling. In other words, recycling is understood in particular to mean the reuse or further use of the material without thermal recovery.
  • the material part removed from the material stream can, for example, be transferred to a suitable collection container. It is also possible for the material part to be transferred to a single-material stream, for example, onto a suitable conveyor belt.
  • identifying that the material part is part of a container made of pulp can be done automatically.
  • the sensor system may comprise an optical sensor, for example a camera.
  • the sensor system may comprise a receiver for electromagnetic waves in the long-wave and/or short-wave and/or ultra-high-frequency and/or microwave range.
  • the sensor system may comprise a source of infrared and/or UV radiation and/or a sensor for infrared and/or UV radiation.
  • the sensor system may comprise a sensor for measuring magnetic and/or electric fields or for measuring changes in such fields.
  • the sensor system may comprise a combination of different sensor types.
  • Sensors of the sensor system can be arranged above the material flow. Alternatively or additionally, sensors of the sensor system can be arranged to the side of the material flow. It is also possible for sensors of the sensor system to be arranged below a transport device, e.g., a conveyor belt, on which the material flow is conveyed.
  • a transport device e.g., a conveyor belt
  • the at least one unique feature can comprise a signal emitted by a transponder, in particular an RFID transponder, which is part of the material part.
  • a transponder in particular an RFID transponder
  • Suitable transponders can be very small and arranged at various locations on the pulp container. They can, for example, be located inside the container or even in the container wall. This allows the transponders to be mounted inconspicuously, i.e., without disrupting the design of the pulp container, yet still enable unique identification of the pulp container.
  • the transponder signal can be reliably detected even if the view of the material part is obscured, for example, by other waste or similar.
  • the at least one unique feature may further comprise an engraving present on the material part.
  • the at least one unique feature may comprise a three-dimensional structure on the material part.
  • the at least one unique feature may comprise an imprint on the material part, in particular an imprint applied directly to a surface of the material part, wherein the imprint may be applied to any part of the surface.
  • the imprint may be applied at least partially to the material part using an ink invisible to the human eye. This may also enable unique identification of the material part without compromising the design of the pulp container.
  • the at least one unique feature can comprise a marking, in particular a holographic marking, on the material part.
  • the at least one unique feature can comprise a code, in particular a QR code and/or a barcode, which is applied to the material part.
  • the at least one unique feature can comprise a digital watermark on the material part.
  • a digital watermark is understood here in particular to be a marking that is interwoven with another pattern, for example a print, but is not directly perceptible by a human.
  • a pixel pattern can be hidden in a print, which can only be detected and identified as a watermark through digital analysis of the print.
  • One of the at least one unique features can be arranged on a side of the material part that corresponds to an outer side of a pulp container, in particular a bottle. It is further possible for one of the at least one unique features to be arranged on a side of the material part that corresponds to an inner side of a pulp container, in particular a bottle.
  • the pulp container can have several of the unique features mentioned above.
  • the pulp container can have different types of unique features, but it is also possible for the pulp container to have one type of different feature in several places. A combination of these variants is also possible.
  • the sensor system it is possible for the sensor system to be configured to detect several of the unique features mentioned above. Because the pulp container has several unique features and because the sensor system is configured to detect these several unique features, the material part can be clearly identified as belonging to the pulp container, even if the material part is partially covered or the material part merely represents a part of the pulp container, for example if the pulp container is broken.
  • the pulp container it is possible for the pulp container to have an imprint applied to it that fluoresces when exposed to UV light.
  • one or more RFID transponders can be arranged on or in the pulp container, particularly at locations not covered by the imprint.
  • the sensor system can comprise a UV lamp that causes the imprint to fluoresce, a camera that detects the fluorescent light, and an RFID receiver.
  • parts of the pulp container bearing the imprint can be identified using the detected fluorescent radiation, while other parts of the pulp container can be identified by detecting the signal from the RFID transponder.
  • control device can be configured to identify that the material part is part of a pulp container based solely on part of the at least one unique feature.
  • the at least one unique feature can comprise a printed pattern and/or a three-dimensional structure, and for the control device to be configured to recognize the pattern or structure even if the sensor system only partially detects the pattern or structure.
  • the control device can be configured to use corresponding pattern recognition systems. It is further possible for the control device to be configured to use artificial intelligence or machine learning methods for this purpose.
  • control device can be configured to identify certain properties of the pulp container based on the unique feature.
  • the certain properties can in particular relate to the material composition of the pulp.
  • the control device can be configured to detect whether the pulp comprises one or more of the above-mentioned fibers.
  • the certain properties can relate to a best-before date of the pulp container and/or dimensions of the pulp container and/or a closure type of the pulp container and/or a calorific value of the pulp container and/or a color of the pulp container. It is possible for the certain properties to be encoded in the unique feature. By identifying certain properties of the pulp container based on the unique feature, the collection of material that is as pure as possible for subsequent recycling of the material can be further improved.
  • control device it is possible for the control device to be configured to detect the size of the material part based on the data from the sensor system. For example, it is possible for the control device to be configured to process image data to determine the size of the material part. For example, the size can be determined based on a comparison of the size of an imprint or part of an imprint with the detected outlines of the material part. The size can be determined only after the material part has been identified based on the at least one unique feature in order to conserve computing resources.
  • Controlling the sorting device can include controlling a compressed air device to remove the material part from the material stream.
  • a suitable compressed air device relatively light pulp material parts can be easily blown out of the material stream.
  • Controlling the compressed air device can also be based on a determined size of the material part. For example, it is possible to select a lower compressed air flow strength for a smaller part than for a larger part.
  • the sorting device can include controlling another discharge element, for example a pusher.
  • the invention further provides a device for sorting a material stream of a sorting system, wherein the device is configured to carry out a method having one or more of the features described above.
