Description

Die vorliegende Erfindung betrifft eine Sensorvorrichtung für einen Messerhalter und insbesondere einen Messerhalter mit einer solchen Sensorvorrichtung, sowie bevorzugt eine Längsschneidemaschine mit einem entsprechenden Messerhalter.The present invention relates to a sensor device for a knife holder and in particular to a knife holder with such a sensor device, and preferably to a longitudinal cutting machine with a corresponding knife holder.

Aus DE 299 15 564 U1 ist ein Messerhalter für eine Längsschneidemaschine bekannt. Der Messerhalter umfasst eine Befestigungsvorrichtung zur Anbringung des Messerhalters an eine Längsschneidemaschine sowie einen gegenüber der Befestigungsvorrichtung absenkbaren Messerkopf. An dem Messerkopf ist ein drehbar gelagerter Messerträger für ein Rundmessers angebracht, wobei das Rundmesser mittels einer Ringmutter auf dem Messerträger befestigt werden kann. DE 299 15 564 U1 schlägt vor, dass ein Sensor zur Erfassung der Rotationsgeschwindigkeit entweder in dem Kugellager des Messerkopfes oder an einer anderen Stelle des Messerhalters relativ zu dem drehbar gelagerten Messerträger angeordnet ist. Um die Rotationsgeschwindigkeit des Messers erfassen zu können, muss also ein Sensor in dem Messerhalter integriert werden, was eine Nachrüstung aufwendig macht.Out DE 299 15 564 U1 a knife holder for a longitudinal cutting machine is known. The knife holder comprises a fastening device for attaching the knife holder to a longitudinal cutting machine and a knife head that can be lowered with respect to the fastening device. A rotatably mounted knife carrier for a circular knife is attached to the knife head, and the circular knife can be fastened to the knife carrier by means of a ring nut. DE 299 15 564 U1 suggests that a sensor for detecting the speed of rotation is arranged either in the ball bearing of the cutter head or at another location on the cutter holder relative to the rotatably mounted cutter carrier. In order to be able to detect the speed of rotation of the knife, a sensor must be integrated in the knife holder, which makes retrofitting expensive.

Aufgabe der vorliegenden Erfindung ist es daher, die mit Bezug zum Stand der Technik geschilderten Nachteile zu beseitigen und insbesondere eine Sensorvorrichtung für einen Messerhalter anzugeben, die einfach nachrüstbar oder austauschbar an dem Messerhalter befestigt werden kann und mit der eine oder mehrere Größen des Schneidvorganges erfasst werden können, so dass auf den Verschleiß des Messers geschlossen werden kann.The object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and, in particular, to provide a sensor device for a knife holder that can be easily retrofitted or exchangeably attached to the knife holder and with which one or more variables of the cutting process can be detected so that conclusions can be drawn about the wear and tear on the knife.

Gelöst wird die Aufgabe durch eine Sensorvorrichtung mit den Merkmalen des unabhängigen Anspruchs. Vorteilhafte Weiterbildungen der Sensorvorrichtung sind in den abhängigen Ansprüchen und in der Beschreibung angegeben, wobei einzelne Merkmale der vorteilhaften Weiterbildungen in technisch sinnvoller Weise miteinander kombinierbar sind.The object is achieved by a sensor device with the features of the independent claim. Advantageous further developments of the sensor device are specified in the dependent claims and in the description, with individual features of the advantageous further developments being able to be combined with one another in a technically meaningful manner.

Gelöst wird die Aufgabe insbesondere durch eine Sensorvorrichtung für einen Messerhalter, umfassend einen Grundkörper zur Befestigung der Sensorvorrichtung an einem Messerhalter insbesondere an einem Messerhalter für eine Längsschneidemaschine, mindestens einen an dem Grundkörper befestigten Sensor zur Erfassung einer Größe und einen an dem Grundkörper befestigten Sender zur kabellosen Übertragung der von dem Sensor erfassten Größe.The object is achieved in particular by a sensor device for a knife holder, comprising a base body for fastening the sensor device to a knife holder, in particular to a knife holder for a longitudinal cutting machine, at least one sensor fastened to the base body for detecting a size, and a wireless transmitter fastened to the base body Transmission of the size detected by the sensor.

Der Grundkörper ist ein solches Bauteil eines Messerhalters, welches sich während des Schneidvorganges zusammen mit dem Messer bewegt. Die Bewegung des Messers während des Schneidvorganges entspricht also der Bewegung des Grundkörpers während des Schneidvorganges. Bevorzugt ist der Grundkörper zur Befestigung eines Rundmessers an einem Messerkopf eines entsprechenden Messerhalters eingerichtet. In diesem Fall führen der Grundkörper und das Rundmesser während des Schneidvorganges eine Rotationsbewegung aus.The main body is such a component of a knife holder, which moves together with the knife during the cutting process. The movement of the knife during the cutting process corresponds to the movement of the base body during the cutting process. The base body is preferably set up for fastening a circular knife to a knife head of a corresponding knife holder. In this case, the main body and the circular knife perform a rotational movement during the cutting process.

Der Grundköper ist beispielsweise als Messerträger, bevorzugt als Messerträger für ein Rundmesser ausgebildet. Bei der Ausbildung als Messerträger für ein Rundmesser ist der Grundkörper insbesondere rotationssymmetrisch ausgebildet, wobei der Grundkörper einen ringförmigen Bund hat, auf den das Rundmesser aufgesetzt werden kann und an den sich eine Anschlagsfläche für das Rundmesser anschließt, an welche das Rundmesser zur Anlage kommt. Das Rundmesser kann sodann mittels einer Ringmutter auf dem Messerträger befestigt werden, der hierzu ein Außengewinde auf dem ringförmigen Bund aufweist.The basic body is designed, for example, as a knife carrier, preferably as a knife carrier for a circular knife. When designed as a knife carrier for a circular knife, the base body is particularly rotationally symmetrical, the base body having an annular collar on which the circular knife can be placed and which is followed by a stop surface for the circular knife on which the circular knife comes to rest. The circular knife can then be fastened to the knife carrier by means of a ring nut, which for this purpose has an external thread on the annular collar.

Alternativ kann der Grundkörper auch als Ringmutter ausgebildet sein, mit der ein Rundmesser auf einem Messerträger befestigt werden kann. Die Ringmutter weist hierzu auf ihrer radialen Innenfläche ein Innengewinde auf.Alternatively, the base body can also be designed as a ring nut with which a circular knife can be attached to a knife carrier. For this purpose, the ring nut has an internal thread on its radial inner surface.

In einer weiteren Ausführungsform kann der Grundkörper auch als insbesondere ringförmige Unterlegscheibe ausgebildet sein, die während des Schneidvorganges zwischen dem (Rund-)Messer und dem Messerträger oder zwischen dem (Rund-)Messer und der Ringmutter angeordnet ist.In a further embodiment, the base body can also be designed as a particularly ring-shaped washer which is arranged between the (round) knife and the knife carrier or between the (round) knife and the ring nut during the cutting process.

Die Erfindung betrifft auch einen Messerhalter, an dem eine erfindungsgemäße Sensorvorrichtung angebracht ist. Der Messerhalter umfasst insbesondere eine Befestigungsvorrichtung zur Anbringung des Messerhalters an einer Längsschneidemaschine sowie einen Messerkopf, an dem ein Messerträger befestigt werden kann. Der Messerkopf ist insbesondere relativ zu der Befestigungsvorrichtung verstellbar (beispielsweise absenkbar/schwenkbar). Insbesondere wenn der Messerhalter keinen aktiven Antrieb für den Messerträger/Messer hat, wird dieser insbesondere als Obermesser in einer Längsschneidemaschine eingesetzt, in der das zugehörige Messer passiv durch entsprechende Untermesser angetrieben wird. Es kann aber auch vorgesehen sein, dass der Messerkopf aktiv antreibbar ist, so dass der Messerhalter als Untermesser in einer Längsschneidemaschine eingesetzt werden kann. Die vorliegende Erfindung betrifft daher auch eine Längsschneidemaschine mit mindestens einem oder mehreren Messerhaltern, die eine erfindungsgemäße Sensorvorrichtung aufweisen.The invention also relates to a knife holder to which a sensor device according to the invention is attached. The knife holder comprises in particular a fastening device for attaching the knife holder to a longitudinal cutting machine and a knife head to which a knife carrier can be fastened. The cutter head is in particular adjustable (for example, lowerable / pivotable) relative to the fastening device. In particular, if the knife holder does not have an active drive for the knife carrier / knife, it is used in particular as an upper knife in a longitudinal cutting machine in which the associated knife is passively driven by corresponding lower knife. However, it can also be provided that the cutter head can be actively driven so that the cutter holder acts as a lower cutter can be used in a longitudinal cutting machine. The present invention therefore also relates to a longitudinal cutting machine with at least one or more knife holders which have a sensor device according to the invention.

Die Erfindung sieht nun in ihrem Grundgedanken vor, dass ein Sensor zur Erfassung von Größen wie Betriebsparametern oder Umwelteinflüssen unmittelbar an einem einfach austauschbaren und/oder nachrüstbaren Bauteil eines Messerhalters befestigt ist, wobei die erfasste(n) Größe(n) mittels eines Senders drahtlos zu einer übergeordneten Einheit übermittelt werden kann, die wiederum durch Auswertung der übermittelten Größe(n) beispielsweise auf einen Verschleiß des zugehörigen Messers schließen kann. Somit kann ein ursprünglich nicht zur Erfassung von Betriebsparametern ausgebildeter Messerhalter einfach nachgerüstet werden beziehungsweise es kann ein Messerhalter bereitgestellt werden, dessen Sensorvorrichtung im Falle eines Versagens einfach ausgetauscht werden kann.The basic idea of the invention now provides that a sensor for detecting variables such as operating parameters or environmental influences is attached directly to an easily replaceable and / or retrofittable component of a knife holder, with the detected variable (s) being transmitted wirelessly by means of a transmitter can be transmitted to a higher-level unit, which in turn can in turn, by evaluating the transmitted variable (s), for example, inferring wear on the associated knife. Thus, a knife holder that was not originally designed to detect operating parameters can simply be retrofitted, or a knife holder can be provided whose sensor device can simply be replaced in the event of failure.

Bevorzugt umfasst die Sensorvorrichtung nicht nur genau einen, sondern mehrere Sensoren zur Erfassung unterschiedlicher Größen.The sensor device preferably comprises not just one, but several sensors for detecting different sizes.

Beispielsweise kann ein Sensor als Beschleunigungssensor ausgebildet sein, mit dem auf die Geschwindigkeit (insbesondere Drehzahl) des entsprechenden Messers geschlossen werden kann. Hieraus lässt sich wiederum auf die Laufmeter des zugehörigen Messers und somit auf den Verschleiß des Messers schließen.For example, a sensor can be designed as an acceleration sensor with which the speed (in particular rotational speed) of the corresponding knife can be deduced. This in turn allows conclusions to be drawn about the running meters of the associated knife and thus about the wear and tear on the knife.

Ein (weiterer) Sensor kann als Lichtsensor ausgebildet sein, mit dem detektiert werden kann, ob ein Messer von dem Messerträger entfernt wurde. Hierzu ist der Lichtsensor insbesondere vom Inneren des Grundkörpers auf eine nach außen gerichtete Öffnung im Grundkörper gerichtet, wobei die Öffnung im Betrieb (also im montierten Zustand) des Messerhalters von einem weiteren Bauteil verschlossen ist. Im montierten Zustand fällt somit kein Licht auf den Lichtsensor, während bei Demontage des Messers Licht von dem Lichtsensor detektiert würde, so dass daraus geschlossen werden kann, dass das Messer ausgetauscht wurde. Der Lichtsensor muss nicht zwangsweise zur Detektion von sichtbarem Licht eingerichtet sein, sondern könnte auch beispielsweise Infrarotstrahlung oder UV-Strahlung detektieren.A (further) sensor can be designed as a light sensor, with which it can be detected whether a knife has been removed from the knife carrier. For this purpose, the light sensor is directed in particular from the interior of the base body to an outwardly directed opening in the base body, the opening being controlled by a knife holder during operation (that is to say in the assembled state) another component is closed. In the assembled state, no light falls on the light sensor, while light would be detected by the light sensor when the knife is dismantled, so that it can be concluded from this that the knife has been replaced. The light sensor does not necessarily have to be set up to detect visible light, but could also detect infrared radiation or UV radiation, for example.

Mindestens ein (weiterer) Sensor kann als Umweltsensor zur Erfassung der Luftfeuchte, des Luftdrucks und/oder der Temperatur ausgebildet sein, mit dem auf das Messer wirkende Umwelteinflüsse erkannt werden können.At least one (further) sensor can be designed as an environmental sensor for detecting the air humidity, the air pressure and / or the temperature, with which environmental influences acting on the knife can be recognized.

Ein (weiterer) Sensor kann als Ortssensor ausgebildet sein, mit dem auf die Lage der Sensorvorrichtung im Raum geschlossen werden kann. Somit wäre feststellbar, an welchem Messerhalter im Raum die Sensorvorrichtung befestigt ist. Ein solcher Ortssensor kann beispielsweise zur Einrichtung eines Bluetooth (Low Energy) Mesh Netzwerkes eingerichtet sein.A (further) sensor can be designed as a location sensor with which the position of the sensor device in space can be inferred. It would thus be possible to determine which knife holder in the room the sensor device is attached to. Such a location sensor can be set up, for example, to set up a Bluetooth (low energy) mesh network.

Die Sensorvorrichtung umfasst bevorzugt einen Beschleunigungssensor. Weitere Sensoren können auch vorgesehen sein. Insbesondere zusätzlich zu dem Beschleunigungssensor ein Lichtsensor vorgesehen.The sensor device preferably comprises an acceleration sensor. Further sensors can also be provided. In particular, a light sensor is provided in addition to the acceleration sensor.

Der Sender zur drahtlosen Übertragung der von dem mindestens einen Sensor erfassten Größe kann nach einem beliebigen Standard zur kabellosen Datenübertragung eingerichtet sein. Bevorzugt sendet der Sender nach dem mit Bluetooth(-Standard).The transmitter for wireless transmission of the variable detected by the at least one sensor can be set up according to any standard for wireless data transmission. The transmitter preferably transmits according to the Bluetooth (standard).

Während es prinzipiell möglich ist, dass die gemessene(n) Größen unmittelbar an eine übergeordnete Einheit gesendet werden, kann alternativ oder zusätzlich vorgesehen sein, dass die Sensorvorrichtung einen Speicher aufweist, auf dem die von dem mindestens einen Sensor erfasste(n) Größe(n) (zwischen)gespeichert werden, wobei eine Datenübertragung in regelmäßigen Abständen oder nach einem vorgebbaren Intervall erfolgt. Es kann auch vorgesehen sein, dass die auf dem Speicher hinterlegten Größen auf Abfrage übermittelt werden.While it is in principle possible for the measured variable (s) to be sent directly to a higher-level unit, it can alternatively or additionally be provided that the sensor device has a memory on which the variable (s) recorded by the at least one sensor ) (temporarily) saved data transmission takes place at regular intervals or after a predefinable interval. It can also be provided that the quantities stored in the memory are transmitted on request.

Es kann zudem vorgesehen sein, dass eine Energieversorgungsquelle (beispielsweise Akku, Kondensator, Batterie etc.) für den Sender und/oder den Sensor an dem Grundkörper befestigt ist.It can also be provided that an energy supply source (for example rechargeable battery, capacitor, battery, etc.) for the transmitter and / or the sensor is attached to the base body.

Um zu vermeiden, dass die Energieversorgungsquelle ausgetauscht werden muss, kann auch vorgesehen sein, dass in dem Grundkörper eine Vorrichtung zum Aufladen der Energieversorgungsquelle vorgesehen ist, die die Energie aus der Bewegung/Beschleunigung des Grundkörpers in elektrische Energie umwandelt.In order to avoid having to replace the energy supply source, it can also be provided that a device for charging the energy supply source is provided in the base body, which device converts the energy from the movement / acceleration of the base body into electrical energy.

Der mindestens eine Sensor, der Sender und/oder die Energieversorgungsquelle sind auf geeignete Weise kraft-, form- und/oder stoffschlüssig an dem Grundkörper befestigt. In einer bevorzugten Ausführungsform sind die Komponenten in dem Grundkörper vergossen, wobei in jedem Fall sichergestellt ist, dass zumindest eine Antenne des Senders so angeordnet ist, dass eine kabellose Übertragung der von dem Sensor erfassten Größe erfolgen kann.The at least one sensor, the transmitter and / or the energy supply source are fastened to the base body in a suitable manner with a force fit, form fit and / or material fit. In a preferred embodiment, the components are encapsulated in the base body, it being ensured in any case that at least one antenna of the transmitter is arranged in such a way that the variable detected by the sensor can be transmitted wirelessly.

Die Erfindung sowie das technische Umfeld werden im Folgenden anhand der Figuren beispielhaft erläutert. Es zeigen schematisch

The invention and the technical environment are explained below by way of example with reference to the figures. It show schematically
Figure 1:
a knife holder and
Figure 2:
a ring nut.

Der in Figur 1 dargestellte Messerhalter 1 umfasst eine Befestigungsvorrichtung 11 zur Befestigung des Messerhalters 1 an einer Längsschneidemaschine sowie einen gegenüber der Befestigungsvorrichtung 11 absenkbaren Messerkopf 2. In der Befestigungsvorrichtung 11 können Mittel zum Absenken des Messerkopfes 2 vorgesehen sein.The in Figure 1 The knife holder 1 shown comprises a fastening device 11 for fastening the knife holder 1 to a longitudinal cutting machine and a knife head 2 that can be lowered with respect to the fastening device 11. Means for lowering the knife head 2 can be provided in the fastening device 11.

An dem Messerkopf 2 ist ein drehbar gelagerter Messerträger 3 befestigt, auf dem mittels einer als Sensorvorrichtung 4 ausgebildeten Ringmutter ein Rundmesser 5 befestigt ist. Die als Sensorvorrichtung 4 ausgebildete Ringmutter ist in Figur 2 dargestellt und umfasst einen Grundkörper 6, an den zwei Sensoren 7, zwei Energieversorgungsquellen 9 und ein Sender 8 befestigt sind, die über eine Leitung 10 miteinander verbunden sind. Der eine Sensor 7 ist als Beschleunigungssensor ausgeführt, während der andere Sensor 7 als Lichtsensor ausgeführt ist.A rotatably mounted knife carrier 3 is fastened to the knife head 2, on which a circular knife 5 is fastened by means of an annular nut designed as a sensor device 4. The ring nut designed as a sensor device 4 is shown in FIG Figure 2 shown and comprises a base body 6, to which two sensors 7, two energy supply sources 9 and a transmitter 8 are attached, which are connected to one another via a line 10. One sensor 7 is designed as an acceleration sensor, while the other sensor 7 is designed as a light sensor.

Da die als Ringmutter ausgebildete Sensorvorrichtung 4 gemeinsam mit dem Rundmesser 5 rotiert, kann über den Beschleunigungssensor 7 auf die Drehzahl und damit bei Kenntnis des Durchmessers des Rundmesser 5 auf die Laufmeter des Rundmessers 5 geschlossen werden, wodurch wiederum auf den Verschleiß des Rundmessers 5 geschlossen werden kann. Der Lichtsensor 7 ist so angeordnet, dass im Betrieb kein Licht auf den Lichtsensor 7 fällt, da eine entsprechende Öffnung von einem anderen Bauteil des Messerhalters 1 verdeckt ist. Wird nun die Ringmutter zum Wechsel des Rundmessers 5 von dem Messerhalter 1 entfernt, so fällt Licht auf den Lichtsensor 7, wodurch auf einen Messerwechsel geschlossen werden kann.Since the sensor device 4, which is designed as a ring nut, rotates together with the circular knife 5, the acceleration sensor 7 can be used to infer the speed and, if the diameter of the circular knife 5 is known, the running meters of the circular knife 5, which in turn indicates the wear on the circular knife 5 can. The light sensor 7 is arranged in such a way that no light falls on the light sensor 7 during operation, since a corresponding opening is covered by another component of the knife holder 1. If the ring nut is now removed from the knife holder 1 in order to change the circular knife 5, light falls on the light sensor 7, which means that a knife change can be concluded.

Die von den Sensoren 7 ermittelten Größen werden über den Sender 8 kabellos an eine übergeordnete Einheit übermittelt, die gegebenenfalls auch auf weitere Betriebsparameter des Messerhalters 1 beziehungsweise der Längsschneidemaschine zurückgreifen kann.The variables determined by the sensors 7 are transmitted wirelessly via the transmitter 8 to a higher-level unit which, if necessary, can also access further operating parameters of the knife holder 1 or the longitudinal cutting machine.
