Description

Die vorliegende Erfindung betrifft ein System zur Überwachung des Zustands eines Siebkorbs eines Sortierers zur Behandlung einer Faserstoffsuspension.The present invention relates to a system for monitoring the condition of a screen basket of a sorter for treating a pulp suspension.

Ziel beim Sortieren ist das Abtrennen von störenden festen Bestandteilen aus Faserstoffsuspensionen. Die Trennung erfolgt durch Sieben nach den Partikelmerkmalen Größe, Gestalt und Verformbarkeit. Die Sortierung ist ein wichtiges Trennverfahren bei der Aufbereitung von Altpapier. Abhängig vom Auflösegrad und der Beladung der Suspension mit Fremdstoffen und Faserstippen werden unterschiedliche Sortierer eingesetzt. Dabei werden u.a. sogenannte Korbsortierer mit einem in einem Gehäuse angeordneten Siebkorb verwendet.The aim of sorting is the separation of interfering solid constituents from pulp suspensions. The separation is carried out by screening according to the particle characteristics of size, shape and deformability. The sorting is an important separation process in the processing of waste paper. Depending on the degree of dissolution and the loading of the suspension with foreign matter and fiber fins different sorters are used. Thereby u.a. so-called basket sorter used with a screen basket arranged in a housing.

Bei den bisher bekannten Korbsortierern werden die technischen Daten des Siebkorbs auf einem Endring des Siebkorbs eingeschlagen. Da der Siebkorb im Gehäuse des betreffenden Sortierers angeordnet ist, ist das Ablesen dieser technischen Daten relativ aufwendig. Zudem bleibt der Verschleißzustand des Siebkorbs im ungewissen, zumal auch kein Lebenslauf oder Historie für die Siebkörbe vorliegt und auch keine Betriebsdaten zur Verfügung stehen.In the basket sorters known hitherto, the technical data of the screen basket are taken on an end ring of the screen basket. Since the screen basket is arranged in the housing of the respective sorter, the reading of these specifications is relatively expensive. In addition, the state of wear of the strainer basket remains uncertain, especially as there is no curriculum vitae or history for the baskets and no operating data is available.

Der Erfindung liegt die Aufgabe zugrunde, ein System zur Überwachung des Zustands eines Siebkorbs eines Sortierers zur Behandlung einer Faserstoffsuspension anzugeben, bei dem die zuvor genannten Probleme beseitigt sind. Dabei soll insbesondere ein schnelleres fehlerfreies Auslesen der den Siebkorb betreffenden technischen Daten gewährleistet und eine umfassendere Überwachung des Zustands des Siebkorbs von außen ermöglicht werden.The invention has for its object to provide a system for monitoring the state of a screen basket of a sorter for the treatment of a pulp suspension, in which the aforementioned problems are eliminated. In particular, a faster error-free readout of the screen basket relating to technical data is to be ensured and a more comprehensive monitoring of the state of the screen basket from the outside is made possible.

Erfindungsgemäß wird die Aufgabe durch ein System mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen des erfindungsgemäßen Systems ergeben sich aus den Unteransprüchen, der vorliegenden Beschreibung sowie der Zeichnung.According to the invention the object is achieved by a system having the features of claim 1. Preferred embodiments of the invention Systems will become apparent from the dependent claims, the present description and the drawings.

Das erfindungsgemäße System zur Überwachung des Zustands eines Siebkorbs eines Sortierers zur Behandlung einer Faserstoffsuspension umfasst eine dem in einem Gehäuse des Sortierers angeordneten Siebkorb zugeordnete kabellose Identifikationseinheit und eine externe, insbesondere mobile Leseeinheit zum berührungslosen Auslesen von den Siebkorb betreffenden technischen Daten aus der Identifikationseinheit und zur Herstellung einer Verbindung mit einer weitere den Sortierer betreffenden Daten enthaltenden externen Datenbank.The system according to the invention for monitoring the condition of a screen basket of a sorter for treating a pulp suspension comprises a wireless identification unit assigned to the screen basket arranged in a sorter housing and an external, in particular mobile reading unit for non-contact reading of technical data relating to the screen basket from the identification unit and for production a connection to another external database containing the sorter data.

Aufgrund dieser Ausbildung können die den Siebkorb betreffenden technischen Daten kabel- und berührungslos von außen, d.h. von außerhalb des Gehäuses des Sortierers schnell und zuverlässig ausgelesen werden. Zudem kann über die externe Leseeinheit auf in einer externen Datenbank enthaltene weitere den Sortierer betreffende Daten zugegriffen werden, womit eine umfassendere Überwachung des Zustands des Siebkorbs ermöglicht wird. Dabei kann beim Einbau des Siebkorbs eine entsprechende Siebkorbinformation in die externe Datenbank eingelesen werden. Beim anschließenden Auslesen der den Siebkorb betreffenden technischen Daten aus der dem Siebkorb zugeordneten Identifikationseinheit kann dann die erforderliche Zuordnung von in der Datenbank enthaltenen Daten zu diesem Siebkorb hergestellt werden. Die weiteren den Sortierer betreffenden Daten können beispielsweise über ein Steuerungssystem der Fabrik, in der der Sortierer installiert ist, gesammelt und der externen Datenbank zugeführt werden. Vertriebsmitarbeitern und Kunden kann jeweils eine insbesondere mobile Leseeinheit ausgehändigt werden, so dass diese den Siebkorb von außen, d.h. von außerhalb des Gehäuses kontrollieren können.Due to this design, the technical data relating to the screen basket can be transmitted from the outside, in a cable-free and contact-free manner. be read from outside the sorter's housing quickly and reliably. In addition, via the external reading unit, further data related to the sorter may be accessed in an external database, thereby enabling a more comprehensive monitoring of the state of the screen basket. In this case, a corresponding screen basket information can be read into the external database when installing the screen basket. During the subsequent readout of the technical data relating to the screen basket from the identification unit assigned to the screen basket, the required assignment of data contained in the database to this screen basket can then be established. The further data relating to the sorter can, for example, be collected via a control system of the factory in which the sorter is installed and supplied to the external database. Sales staff and customers can each be given a mobile reading unit, in particular, so that the outside of the screen basket, i. from outside the case.

Bevorzugt umfasst eine jeweilige Leseeinheit ein Display zur Wiedergabe von weiteren den Sortierer betreffenden von der externen Datenbank abgerufenen Daten. Gemäß einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Systems umfasst die Identifikationseinheit zumindest einen RFID-Chip (RFID = radiofrequency identification).Preferably, a respective reading unit comprises a display for displaying further data relating to the sorter retrieved from the external database. According to an expedient practical embodiment of the system according to the invention, the identification unit comprises at least one RFID chip (RFID = radiofrequency identification).

Ein solcher RFID-Chip stellt insbesondere einen Transponder dar, der die den Siebkorb betreffenden technischen Daten enthält. Der Transponder ist ein Funk-Kommunikationsmittel, das eingehende Signale aufnimmt und automatisch beantwortet. Die Kopplung kann durch von der Leseeinheit erzeugte magnetische Wechselfelder geringer Reichweite oder durch hochfrequente Radiowellen erfolgen. Damit können nicht nur Daten übertragen, sondern auch der Transponder mit Energie versorgt werden. Für größere Reichweiten ist beispielsweise auch ein aktiver RFID-Chip mit eigener Stromversorgung denkbar.Such an RFID chip in particular represents a transponder which contains the technical data relating to the screen basket. The transponder is a radio communication device that receives incoming signals and automatically answers. The coupling can be done by magnetic field generated by the reading unit short range or by high-frequency radio waves. This not only allows data to be transferred, but also the transponder can be supplied with energy. For larger ranges, for example, an active RFID chip with its own power supply is conceivable.

Das Lesegerät kann eine Software enthalten, die den eigentlichen Leseprozess zum Auslesen der den Siebkorb betreffenden technischen Daten aus der Identifikationseinheit bzw. dem RFID-Chip steuert. Zudem kann die Leseeinheit eine RFID-Middleware mit einer Schnittstelle zu der externen Datenbank umfassen.The reading device may contain software which controls the actual reading process for reading out the technical data relating to the screen basket from the identification unit or the RFID chip. In addition, the reading unit may comprise an RFID middleware with an interface to the external database.

Die Identifikationseinheit umfasst bevorzugt zumindest einen dem Siebkorb des Sortierers zugeordneten RFID-Chip.The identification unit preferably comprises at least one RFID chip assigned to the screen basket of the sorter.

Gemäß einer zweckmäßigen praktischen Ausführungsform des erfindungsgemäßen Systems umfasst die Identifikationseinheit sowohl einen dem Siebkorb des Sortierers zugeordneten RFID-Chip als auch einen dem Gehäuse des Sortierers zugeordneten RFID-Chip, wobei der dem Siebkorb zugeordnete RFID-Chip über eine Software-Kopplung mit dem dem Gehäuse zugeordneten RFID-Chip koppelbar und der dem Gehäuse zugeordnete RFID-Chip über die Leseeinheit auslesbar ist.According to an expedient practical embodiment of the system according to the invention, the identification unit comprises both an RFID chip assigned to the screen basket of the sorter and an RFID chip assigned to the housing of the sorter, wherein the RFID chip assigned to the screen basket is connected to the housing via a software coupling associated RFID chip coupled and the housing associated with the RFID chip can be read via the reading unit.

Damit kann die Leseeinheit eine Verbindung zwischen dem dem Gehäuse zugeordneten RFID-Chip und der externen Datenbank herstellen. Die Verbindung zwischen dem RFID-Chip und der externen Datenbank wird in diesem Fall nicht durch das in der Regel metallische Gehäuse des Sortierers beeinträchtigt.In this way, the reading unit can establish a connection between the RFID chip assigned to the housing and the external database. The connection between the RFID chip and the external database is not affected in this case by the usually metallic case of the sorter.

Gemäß einer alternativen Ausführungsform des erfindungsgemäßen Systems kann jedoch auch unmittelbar der dem Siebkorb des Sortierers zugeordnete RFID-Chip über die Leseeinheit auslesbar sein.According to an alternative embodiment of the system according to the invention, however, the RFID chip assigned to the screen basket of the sorter can also be read out directly via the reading unit.

Insbesondere in dem Fall, dass unmittelbar der dem Siebkorb des Sortierers zugeordnete RFID-Chip über die Leseeinheit auslesbar ist, ist der dem Siebkorb des Sortierers zugeordnete RFID-Chip bevorzugt im Bereich der über einen Deckel verschließbaren Öffnung des Sortierers angeordnet. Zum Auslesen des betreffenden RFID-Chips kann dann der Deckel des Sortierers abgenommen werden, woraufhin mittels der Leseeinheit unmittelbar der dem Siebkorb des Sortierers zugeordnete RFID-Chip ausgelesen werden kann.In particular, in the event that the RFID chip associated with the screen basket of the sorter can be read out directly via the reading unit, the RFID chip assigned to the screen basket of the sorter is preferably arranged in the region of the opening of the sorter which can be closed by a cover. In order to read out the relevant RFID chip, the lid of the sorter can then be removed, whereupon the RFID chip associated with the screen basket of the sorter can be read out directly by means of the reading unit.

Der dem Siebkorb des Sortierers zugeordnete RFID-Chip kann insbesondere an oder in einem Endring des Siebkorbs angeordnet sein.The RFID chip associated with the screen basket of the sorter can, in particular, be arranged on or in an end ring of the screen basket.

Insbesondere aus den zuvor genannten Gründen ist dabei von Vorteil, wenn der dem Siebkorb des Sortierers zugeordnete RFID-Chip an oder in einem der durch einen Deckel verschließbaren Öffnung des Sortierers benachbarten Endring des Siebkorbs angeordnet ist.In particular, for the reasons mentioned above, it is advantageous if the RFID chip associated with the screen basket of the sorter is arranged on or in one of the openings of the screen basket which can be closed by a lid of the sorter.

Dabei ist der dem Siebkorb des Sortierers zugeordnete RFID-Chip bevorzugt an der der Öffnung des Sortierers zugewandten Oberseite des Endrings angeordnet.Here, the screen basket of the sorter associated RFID chip is preferably arranged on the opening of the sorter facing the top of the end ring.

Von Vorteil ist insbesondere auch, wenn der dem Siebkorb des Sortierers zugeordnete RFID-Chip an der radialen Innenseite des Endrings angeordnet ist, womit die Zugänglichkeit des RFID-Chips zur Ankopplung der Leseeinheit weiter verbessert wird.It is also particularly advantageous if the RFID chip assigned to the screen basket of the sorter is arranged on the radial inner side of the end ring, thus further improving the accessibility of the RFID chip for coupling the reading unit.

Es ist beispielsweise auch eine solche Ausführung denkbar, bei der der dem Siebkorb des Sortierers zugeordnete RFID-Chip versenkt in dem Endring untergebracht ist. Dabei ist der versenkt in dem Endring des Siebkorbs untergebrachte RFID-Chip bevorzugt mit Kunststoff oder vorzugsweise Teflon gekapselt. Eine solche Abdeckung ist zweckmäßig, da der Siebkorb in der Regel wiederaufbereitet, d.h. insbesondere verchromt und elektropoliert wird.For example, such an embodiment is conceivable in which the RFID chip assigned to the screen basket of the sorter is accommodated sunk in the end ring. In this case, the sunk in the end ring of the screen basket housed RFID chip is preferably encapsulated with plastic or preferably Teflon. Such a cover is convenient because the strainer basket is typically recycled, i. especially chromed and electropolished.

Die erwähnte Anordnung des dem Siebkorb des Sortierers zugeordneten RFID-Chips an oder in einem Endring des Siebkorbs trägt unter anderem dem Umstand Rechnung, dass die Endringe eines Stabsiebkorbes mit zwischen diesen Endringen verlaufenden Stäben einem geringeren Verschleiß unterliegen als die Stäbe.The mentioned arrangement of the sieve basket of the sorter associated RFID chips on or in an end ring of the screen basket, inter alia, the fact that the end rings of a Stabsiebkorbes with running between these end rings rods are subject to less wear than the rods.

Die weiteren den Sortierer betreffenden Daten sind bevorzugt zusammen mit den den Siebkorb betreffenden technischen Daten in der externen Datenbank hinterlegt. Über die aus der dem Siebkorb zugeordneten Identifikationseinheit ausgelesenen technischen Daten kann somit die Zuordnung zu den weiteren den Sortierer betreffenden Daten in der externen Datenbank hergestellt werden.The other data relating to the sorter are preferably stored together with the technical data relating to the screen basket in the external database. By means of the technical data read out from the identification unit assigned to the sieve basket, the assignment to the other data relating to the sorter can thus be established in the external database.

Gemäß einer bevorzugten praktischen Ausführungsform des erfindungsgemäßen Systems umfassen die über die Leseeinheit aus der externen Datenbank abrufbaren weiteren den Sortierer betreffenden Daten Fertigungsdaten des Siebkorbs, Lebenslaufdaten des Siebkorbs, Betriebsdaten des Sortierers, Verschleißdaten des Siebkorbs und/oder dergleichen.According to a preferred practical embodiment of the system according to the invention, further data relating to the sorter via the reading unit include production data of the screen basket, cv basket cv data, sorter operation data, wear data of the screen basket and / or the like.

Dabei können die Fertigungsdaten des Siebkorbs beispielsweise die Konstruktion, das Material, die Größe usw. des Siebkorbs betreffende Daten enthalten. Die Lebenslaufdaten des Siebkorbs können beispielsweise Daten bezüglich der Wiederaufbereitung des Siebkorbs, bezüglich Lagerzeiten usw. enthalten. Die Betriebsdaten des Sortierers umfassen beispielsweise die Laufzeit, den Durchfluss/Druck am Einlauf/Auslauf des Sortierers, die Rotationsgeschwindigkeit usw. Diese Informationen können beispielsweise über die Maschinensteuerung des Sortierers erhalten werden.The manufacturing data of the screen basket may contain, for example, data relating to the construction, the material, the size, etc. of the screen basket. The cuvette's cv data may include, for example, data regarding reprocessing of the screen basket, storage times, etc. The operating data of the sorter include, for example, the running time, the flow / pressure at the inlet / outlet of the sorter, the rotational speed etc. This information can be obtained, for example, via the machine control of the sorter.

Von Vorteil ist insbesondere auch, wenn das erfindungsgemäße System Datenverarbeitungsmittel umfasst, um auf der Basis der Lebensdauer vorheriger Siebkörbe, der gesamten bisher vom Siebkorb behandelten Durchsatzmenge, der Rotationsgeschwindigkeit des Siebkorbs, der Energiebilanz zwischen dem Eingang und den Ausgängen des Sortierers und/oder dergleichen den Verschleißgrad des Siebkorbs und damit den nächsten Wechseltermin für den Siebkorb zu ermitteln.It is also of particular advantage if the system according to the invention comprises data processing means for determining the baskets' throughput, the speed of rotation of the strainer basket, the energy balance between the input and the outputs of the sorter and / or the like on the basis of the service life of previous screen baskets To determine the degree of wear of the screen basket and thus the next change date for the screen basket.

Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnung näher erläutert.The invention will be explained in more detail below with reference to an embodiment with reference to the drawing.

In der Zeichnung zeigt Figur 1 in rein schematischer Darstellung eine beispielhafte Ausführungsform eines erfindungsgemäßen Systems 10 zur Überwachung des Zustands eines Siebkorbs 12 eines Sortierers zur Behandlung einer Faserstoffsuspension.In the drawing shows FIG. 1 in a purely schematic representation of an exemplary embodiment of a system 10 according to the invention for monitoring the state of a screen basket 12 of a sorter for the treatment of a pulp suspension.

Das System 10 umfasst gemäß Figur 2 eine dem in einem Gehäuse 24 des Sortierers angeordneten Siebkorb 12 zugeordnete kabellose Identifikationseinheit 14 und eine externe, insbesondere mobile Leseeinheit 16 zum berührungslosen Auslesen von den Siebkorb 12 betreffenden technischen Daten 18 aus der Identifikationseinheit 14 und zur Herstellung einer Verbindung mit einer weitere den Sortierer betreffende Daten enthaltenden externen Datenbank 20.The system 10 includes according to FIG. 2 a wireless identification unit 14 associated with a screen basket 12 arranged in a housing 24 of the sorter and an external, in particular mobile reading unit 16 for non-contact reading of technical data 18 relating to the screen basket 12 from the identification unit 14 and for establishing a connection with a further data relating to the sorter containing external database 20.

Die Leseeinheit 16 kann ein Display zur Wiedergabe von weiteren den Sortierer betreffenden von der externen Datenbank abgerufenen Daten umfassen.The reading unit 16 may include a display for displaying further data related to the sorter retrieved from the external database.

Die Identifikationseinheit 14 kann zumindest einen RFID-Chip umfassen. In diesem Fall umfasst sie zumindest einen dem Siebkorb 12 des Sortierers zugeordneten RFID-Chip.The identification unit 14 may comprise at least one RFID chip. In this case, it comprises at least one RFID chip associated with the screen basket 12 of the sorter.

Gemäß einer beispielhaften Ausführungsform des erfindungsgemäßen Systems kann die Identifikationseinheit 14 sowohl einen dem Siebkorb 12 des Sortierers zugeordneten RFID-Chip als auch einen dem Gehäuse 24 des Sortierers zugeordneten RFID-Chip umfassen, wobei der dem Siebkorb 12 zugeordnete RFID-Chip über eine Software-Kopplung mit dem dem Gehäuse 24 zugeordneten RFID-Chip koppelbar und der dem Gehäuse 24 zugeordnete RFID-Chip über die Leseeinheit 16 auslesbar ist.According to an exemplary embodiment of the system according to the invention, the identification unit 14 may comprise both an RFID chip assigned to the screen basket 12 of the sorter and an RFID chip assigned to the housing 24 of the sorter, wherein the RFID chip associated with the screen basket 12 is connected via a software coupling can be coupled to the RFID chip associated with the housing 24 and the RFID chip assigned to the housing 24 can be read out via the reading unit 16.

Gemäß einer alternativen beispielhaften Ausführungsform des erfindungsgemäßen Systems 10 kann auch unmittelbar der dem Siebkorb 12 des Sortierers zugeordnete RFID-Chip über die Leseeinheit 16 auslesbar sein.According to an alternative exemplary embodiment of the system 10 according to the invention, the RFID chip assigned to the screen basket 12 of the sorter can also be read out via the reading unit 16 directly.

Insbesondere in dem Fall, dass unmittelbar der dem Siebkorb 12 des Sortierers zugeordnete RFID-Chip über die Leseeinheit 16 auslesbar ist, ist der dem Siebkorb 12 des Sortierers zugeordnete RFID-Chip zweckmäßigerweise im Bereich der über einen Deckel verschließbaren Öffnung des Sortierers angeordnet.In particular, in the case where the RFID chip assigned to the screen basket 12 of the sorter can be read out directly via the reading unit 16, the RFID chip assigned to the screen basket 12 of the sorter is expediently arranged in the region of the opening of the sorter which can be closed by a cover.

Dabei kann der dem Siebkorb 12 des Sortierers zugeordnete RFID-Chip insbesondere an oder in einem der durch einen Deckel verschließbaren Öffnung des Sortierers benachbarten Endring 22 des Siebkorbs 12 angeordnet sein. Im vorliegenden Fall ist der dem Siebkorb 12 des Sortierers zugeordnete RFID-Chip entsprechend an oder in dem oberen Endring 22 des Siebkorbs 12 angeordnet.In this case, the RFID chip associated with the screen basket 12 of the sorter can be arranged, in particular, on or in one of the end openings 22 of the screen basket 12 which can be closed by an opening of the sorter which can be closed by a lid. In the present case, the RFID basket associated with the screen basket 12 of the sorter is correspondingly arranged on or in the upper end ring 22 of the screen basket 12.

Dabei kann der dem Siebkorb 12 des Sortierers zugeordnete RFID-Chip beispielsweise an der der Öffnung des Sortierers zugewandten Oberseite des Endrings 22 oder auch an der radialen Innenseite des Endrings 22 angeordnet sein.In this case, the RFID chip associated with the screen basket 12 of the sorter can be arranged, for example, on the upper side of the end ring 22 facing the opening of the sorter or else on the radial inner side of the end ring 22.

Es ist jedoch beispielsweise auch eine solche Ausführung denkbar, bei der der dem Siebkorb 12 des Sortierers zugeordnete RFID-Chip versenkt in dem Endring 22 untergebracht ist. Dabei kann der versenkt in dem Endring 22 des Siebkorbs 12 untergebrachte RFID-Chip mit einer insbesondere aus Kunststoff und vorzugsweise aus Teflon bestehenden Abdeckung versehen sein. Mit einer solchen Abdeckung wird dem Umstand Rechnung getragen, dass der Siebkorb 12 in der Regel wiederaufbereitet, d.h. verchromt und elektropoliert wird.However, it is also conceivable, for example, such a design, in which the screen basket 12 of the sorter associated RFID chip sunk in the end ring 22 is housed. In this case, the sunk in the end ring 22 of the strainer 12th housed RFID chip with a particular plastic and preferably made of Teflon cover be provided. With such a cover the fact is taken into account that the screen basket 12 is usually recycled, ie chromed and electropolished.

Die weiteren den Sortierer betreffenden Daten können zusammen mit den den Siebkorb 12 betreffenden technischen Daten in der externen Datenbank 20 hinterlegt sein. Über die von der Identifikationseinheit 14 eines jeweiligen Siebkorbs 12 ausgelesenen technischen Daten 18 können somit die betreffenden weiteren in der externen Datenbank 20 enthaltenen Daten dem Siebkorb 12 zugeordnet werden.The other data relating to the sorter can be stored in the external database 20 together with the technical data relating to the screen basket 12. By means of the technical data 18 read out by the identification unit 14 of a respective screen basket 12, the relevant further data contained in the external database 20 can thus be assigned to the screen basket 12.

Die über die Leseeinheit 16 aus der externen Datenbank 20 abrufbaren weiteren den Sortierer betreffenden Daten können insbesondere Fertigungsdaten des Siebkorbs 12, Lebenslaufdaten des Siebkorbs 12, Betriebsdaten des Sortierers und/oder dergleichen umfassen. Dabei umfassen die Fertigungsdaten des Siebkorbs 12 beispielsweise die Konstruktion, das Material, die Größe oder dergleichen des Siebkorbs 12 betreffende Daten. Die Lebenslaufdaten des Siebkorbs 12 können beispielsweise Daten zur Wiederaufbereitung des Siebkorbs 12, Lagerzeiten usw. umfassen. Die Betriebsdaten des Sortierers umfassen beispielsweise Daten bezüglich der Laufzeit, des Durchflusses/Drucks am Einlauf/Auslauf des Sortierers, Daten bezüglich der Rotationsgeschwindigkeit des Siebkorbs 12 und/oder dergleichen. Die betreffenden Informationen können insbesondere von der Maschinensteuerung des Sortierers geliefert werden.The further data relating to the sorter that can be called up via the reading unit 16 from the external database 20 may in particular include production data of the screen basket 12, cv data of the screen basket 12, operating data of the sorter and / or the like. Here, the manufacturing data of the screen basket 12 include, for example, the construction, the material, the size or the like of the screen basket 12 relating data. The cv data of the screen basket 12 may include, for example, data for reprocessing the screen basket 12, storage times, etc. The operation data of the sorter include, for example, data regarding the running time, the flow / pressure at the inlet / outlet of the sorter, data relating to the rotational speed of the screen basket 12 and / or the like. The relevant information can be supplied in particular by the machine control of the sorter.

Zudem kann das erfindungsgemäße System 10 beispielsweise im Lesegerät 16 und/oder in der externen Datenbank 20 integrierte Datenverarbeitungsmittel umfassen, um auf der Basis der Lebensdauer vorheriger Siebkörbe, der gesamten bisher vom Siebkorb 12 behandelten Durchsatzmenge, der Rotationsgeschwindigkeit des Siebkorbs 12, der Energiebilanz zwischen dem Eingang und den Ausgängen des Sortierers und/oder dergleichen den Verschleißgrad des Siebkorbs 12 und damit den nächsten Wechseltermin für den Siebkorb 12 zu ermitteln.In addition, the inventive system 10 may include, for example, data processing means integrated into the reader 16 and / or the external database 20 for determining the energy balance between the first baskets, the total throughput rate previously handled by the strainer basket 12, the speed of rotation of the strainer basket 12 Input and the outputs of the sorter and / or the like to determine the degree of wear of the screen basket 12 and thus the next change date for the screen basket 12.
