Definitions
- the invention relates to an apparatus and a method for the detection of successive units of an endless, in a conveying process web with a sensor for detecting along the path changing properties thereof.
- Such devices are well known in the art and are used, for example, in the paper or printing industry for cutting printed or unprinted paper webs into individual sheets or sheets.
- the endless web or the endless paper strip is provided with markings which are located at a predetermined relative position to the desired reference interface , These markings can then be detected by, for example, sensors designed as contrast sensors, each detection of a marking triggering a cutting process.
- a disadvantage of these known devices and methods is the fact that specifically for the processing of the endless web or for cutting a paper strip markings must be provided on the web, which are basically undesirable for design reasons. Furthermore, the markings per unit can undesirably lead to a repeated switching of a contrast scanner, so that it can not be clearly recognized which of the on the desired cutting position related switching operation, which in turn can have a faulty cut result.
- document DE 10154003 A discloses an apparatus and a method according to the preamble of claims 1 and 8, respectively.
- An object of the invention is to develop a device and a method of the type mentioned in such a way that on the one hand can be dispensed with the disadvantageous markings and on the other hand it is ensured that the processing or cutting of the web takes place in each case at the correct position.
- the invention is therefore based on the surprising finding that for the detection of successive units of an endless web not necessarily dedicated markers must be attached, but that it is sufficient, the existing anyway on the web, varying over the length of the web properties sensorially to capture and evaluate in an appropriate manner.
- the changing web properties also have a constant location reference to the transitions of adjacent units, these transitions can also be easily determined with the device according to the invention and with the method according to the invention, so that, for example, automatically a cutting process can be triggered at these transitions.
- the changes to the web properties to be detected are repeated in all units of the web, so that they can be cut, for example, in noisy mutually identical units.
- the repetitive changes in the web properties are not present in all units in the same way.
- a web it is possible for a web to have two different types of units, each of which has mutually repeating changes in web properties, but the changes of one type differ from the other type. In this case, it can then be distinguished according to the invention, of which of the two types is the respectively recognized unit, whereupon a matched to the respective type processing can be triggered.
- the senor is designed to detect a sequence of a plurality of mutually different changes in the web properties. This makes it possible to detect two or more changes in the web properties relative to each unit of the web, which increases the uniqueness of the detection result. If, for example, three different changes per unit are to be detected, of which the last change occurs during the transition to the subsequent unit, it can be checked according to the invention whether the first two changes were detected first, whereupon the third change only counts as a transition to the next unit if the first two changes were detected correctly before. The security and reliability of a correct recognition can thus be significantly increased by this preferred variant of the invention.
- a memory in which a chronological setpoint sequence of the changes to be detected per unit can be stored. Furthermore, an evaluation unit is provided for comparing the actually chronologically detected change sequence with the stored desired sequence, with which it is checked whether the expected change sequence was actually detected and thus a unit was recognized. In the case of the correspondence between the stored desired sequence and the detected change sequence, the evaluation unit can then emit a detection signal related to the detected unit.
- the relative time references and / or the respective type of changes and / or the respective degree of changes can be taken into account in addition to the chronology of the changes. In this case, it is then examined in which temporal relation the detected changes are related to each other and / or of which type and of which magnitude the detected changes were.
- All changes detected on one unit preferably lead to the delivery of only a single detection signal, which can be unambiguously assigned to the respectively detected unit.
- This single detection signal is preferably dependent on a change with a comparatively high degree of change, since such a change, which may be formed for example as a particularly striking, sharp color transition, can be recognized particularly well by the sensor. If the distance between this change and the beginning or the end of the respective unit is known, the start and end of the unit can be identified with a particularly high spatial resolution, since the respective position can be simply calculated from the position of the detected change and the known distance ,
- a delay element may also be provided for triggering the detection signal with an adjustable time delay after detection of the correspondence between the stored desired sequence and the actually detected change sequence.
- a delay element can be taken into account, for example, the fact that a cutting device is behind the sensor according to the invention in the conveying direction and thus must depend on the detection of a unit dependent on the delivery speed time until the detected unit or its beginning or the End is located in the area of the cutting device.
- the delay element can thus be set, for example, exactly so that, depending on the units detected according to the invention, a cut always takes place exactly at the transition between two units by the cutting device.
- the delay element can be considered with the delay element, if the last detection of a change in a unit not at the end of the unit but already before, so that the end of the unit is not yet below the sensor at detection of the last change.
- the delay element is then adjusted in dependence on the conveying speed such that the delay time or at least a component thereof corresponds to the time required to further convey the unit by the distance between the last detected change and the end of the unit.
- the delay element can also be adjusted so that, on the one hand, the latter delay and, on the other hand, the already mentioned distance between the sensor and a cutting device is taken into account.
- the delay times caused by the delay element do not necessarily have to be constant. Rather, they can be adapted to the respective conveying speeds. In particular, however, a change in the delay times during the conveying process of a single web can take place, if this web is conveyed at different times at different speeds.
- a constant delay time can also be given at a constant conveying speed, since in this case, for example, the sensor can simply be displaced along the conveying path as part of a teaching operation, until e.g. a separation process initiated by the sensor always takes place exactly at the transitions between two units.
- conveying speed can be closed from the detected changes on the length of color elements, which are located on the web.
- the beginning and the end of such color elements are detected as changes according to the invention, and the time elapsed between these detection operations can then be considered the conveying speed the length of a color element is calculated and stored.
- the length of the color elements calculated in this way can then be used as a recognition feature for successive units by checking on each unit of the web whether the color elements assigned to the respective unit have the length determined in previous units.
- the conveying speed is known only during a training phase and is no longer known during further operation
- the length of a color element determined in normal operation can be used to calculate the currently present relative conveying speed.
- a normalized conveying speed of 1 may be present within the scope of the teaching process, in which the value of 1, which is also normalized, is determined as the length of a color element, for example. If a length of the color element of 2 is now detected in the normal operation of the system following the training phase, it can be assumed that the instantaneous conveying speed-also normalized-is 0.5.
- the sensor for detecting the changes in web properties used according to the invention can be designed so that it can detect changes in the color, the contrast, the reflectivity and / or other surface textures of the web.
- Different types of changes in the web properties can thus be used to implement the inventive concept, whereby, for example, sensor arrangements consisting of a plurality of sensors can also be used, which can simultaneously detect different types of changes. It is therefore quite possible to detect a single unit by detecting successive changes in the web properties of different types. Basically you will always use those types of changes for the evaluation, with which the amplitude-wise largest sensor signals can be generated, since in this way the risk of misdetections is minimized.
- the senor can be designed as a contrast scanner, which can illuminate the web with different transmission colors. In this case, depending on the color of the changes to be detected during the scanning of each unit, the transmission color can then be changed such that a respective maximum contrast value is established.
- the web investigated according to the invention may be a printed or unprinted paper web.
- the printing ink present on the web can trigger the contrast jumps to be evaluated according to the invention.
- Fig. 1 a portion of an elongate web 1 is shown, which consists of paper and is transported in the conveying direction A.
- Paper web was previously provided in a printing machine, inter alia, with imprints 2, 3, wherein the imprints 2 differ in color from the imprints 3.
- the paper web 1 consists of adjacent, mutually identical units 10. The transition between two adjacent units is in Fig. 1 denoted by the reference numeral 11.
- Fig. 1 It can be seen that the imprints 2, 3 are arranged in all successive units 10 in each case in the same position and in particular at the same relative position with respect to the transitions 11, so that the imprints 2, 3 along the path 1 ultimately form a periodically repeating pattern ,
- a sensor 4 is arranged, which is designed as a contrast sensor, which can illuminate the web 4 with different colors.
- a cutting device 5 is provided, by means of which the web 1 can be cut perpendicular to the conveying direction A.
- Sensor 4 and cutting device 5 are coupled via data and control lines to an evaluation unit 6, which receives and processes data from the sensor 4 and furthermore is able to control the sensor 4 and the cutting device 5.
- FIG. 1 A block diagram of the evaluation unit 6 according to Fig. 1 is in Fig. 2 shown.
- the central component of this evaluation unit 6 is the arithmetic unit 7, which can be formed, for example, as a commercially available microprocessor. Via an interface A, the arithmetic unit 7 receives signals from the sensor 4, via an interface B, the arithmetic unit 7 can control the sensor 4. Via an interface C, the arithmetic unit 7 receives information regarding the current conveying speed of the web 1.
- the arithmetic unit 7 communicates with a memory 8, in which a chronological setpoint sequence of the color changes to be detected by the sensor 4 can be stored.
- the arithmetic unit 7 acts on a delay unit 9 whose delay time .DELTA.t is variably adjustable via the arithmetic unit 7.
- the output of the delay unit 9 is fed to an interface D, which is connected to the cutting device 5 and triggers a cutting operation upon the delivery of a signal via the interface D.
- a chronological setpoint sequence of the color changes to be detected per unit 10 is stored in the memory 8.
- This setpoint sequence can be determined, for example, by means of a teach process via the sensor 4.
- the memory 8 is also stored, in which temporal sequence caused by the imprints 2, 3 changes occur. In concrete terms, it is thus stored with which temporal relation in each case the beginning and end of the imprints 2, 3 pass by the sensor 4 at a predetermined conveying speed.
- the rear end of the imprints 2 in the direction of conveyance A is the most striking color transition in the area of the imprints 2, 3 and the distance d of this color transition from the transition the unit 10 carrying the respective imprint to the next unit 10 is known to the evaluation unit 6.
- the sensor 4 then provides change signals each time the beginning and end of the imprints 2, 3 are passed past the sensor. These data are supplied to the arithmetic unit 7 via the interface A, whereupon the arithmetic unit 7 compares these data with the values stored in the memory 8. If the computing unit 7 determines in the context of a real-time processing that the sequence of detected changes coincides with the sequence stored in the memory 8, it can be assumed that after recognizing the then expected rear end of the imprint 2, which represents the most striking color transition , this rear end of the imprint 2 is just below the sensor 4.
- the arithmetic unit 7 can accurately calculate from the known distance between sensor 4 and cutting device 5 and said distance d, after which delay time the transition 11, which follows the end of the detected imprint 2, comes to lie below the cutting device 5. After elapse of a corresponding delay time .DELTA.t, which is effected by the delay element 9, then a switching signal is output via the interface D to the cutting device, which triggers a cutting process along the transition 11. If the conveying speed changes, the arithmetic unit 7 can calculate a correspondingly adapted delay time ⁇ t, which is then made available to the delay element 9 by the arithmetic unit 7.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Erkennung von aufeinanderfolgenden Einheiten einer endlosen, in einem Förderprozess befindlichen Bahn mit einem Sensor zur Detektion von sich entlang der Bahn ändernden Eigenschaften derselben. Derartige Vorrichtungen sind aus dem Stand der Technik bekannt und werden beispielsweise in der Papier- oder Druckindustrie zum Schneiden von bedruckten oder unbedruckten Papierbahnen in einzelne Blätter oder Bögen eingesetzt. Um einen Schneidvorgang jeweils möglichst genau an einem Übergang zwischen zwei aufeinanderfolgenden Einheiten bzw. Blättern oder Bögen auslösen zu können, wird gemäß Stand der Technik die endlose Bahn bzw. der endlose Papierstreifen mit Markierungen versehen, welche sich an einer vorbestimmten Relativposition zu der gewünschten Sollschnittstelle befinden. Diese Markierungen können dann durch beispielsweise als Kontrasttaster ausgebildete Sensoren erkannt werden, wobei jedes Erkennen einer Markierung einen Schneidprozess auslöst.The invention relates to an apparatus and a method for the detection of successive units of an endless, in a conveying process web with a sensor for detecting along the path changing properties thereof. Such devices are well known in the art and are used, for example, in the paper or printing industry for cutting printed or unprinted paper webs into individual sheets or sheets. In order to be able to trigger a cutting process as accurately as possible at a transition between two successive units or sheets or sheets, according to the prior art, the endless web or the endless paper strip is provided with markings which are located at a predetermined relative position to the desired reference interface , These markings can then be detected by, for example, sensors designed as contrast sensors, each detection of a marking triggering a cutting process.
Nachteilig an diesen bekannten Vorrichtungen und Verfahren ist die Tatsache, dass eigens für die Bearbeitung der endlosen Bahn bzw. für das Schneiden eines Papierstreifens Markierungen auf der Bahn vorgesehen werden müssen, welche aus Designgründen jedoch grundsätzlich unerwünscht sind. Ferner können die Markierungen pro Einheit in unerwünschter Weise zu einem mehrmaligen Schalten eines Kontrasttasters führen, so dass nicht eindeutig erkannt werden kann, welches der auf die gewünschte Schnittposition bezogene Schaltvorgang ist, was dann wiederum einen fehlerhaften Schnitt zur Folge haben kann.A disadvantage of these known devices and methods is the fact that specifically for the processing of the endless web or for cutting a paper strip markings must be provided on the web, which are basically undesirable for design reasons. Furthermore, the markings per unit can undesirably lead to a repeated switching of a contrast scanner, so that it can not be clearly recognized which of the on the desired cutting position related switching operation, which in turn can have a faulty cut result.

Eine Aufgabe der Erfindung besteht darin, eine Vorrichtung und ein Verfahren der eingangs genannten Art derart weiterzubilden, dass einerseits auf die nachteiligen Markierungen verzichtet werden kann und andererseits sichergestellt wird, dass die Bearbeitung bzw. das Schneiden der Bahn jeweils an der korrekten Position erfolgt.An object of the invention is to develop a device and a method of the type mentioned in such a way that on the one hand can be dispensed with the disadvantageous markings and on the other hand it is ensured that the processing or cutting of the web takes place in each case at the correct position.
Diese Aufgabe wird mit einer erfindungsgemäßen Vorrichtung gemäß dem Anspruch 1 gelöst.This object is achieved with a device according to the invention according to claim 1.
Gemäß einem erfindungsgemäßen Verfahren wird die genannte Aufgabe durch die Merkmale des Anspruches 8 gelöst.According to a method of the invention, said object is achieved by the features of claim 8.
Der Erfindung liegt somit die überraschende Erkenntnis zugrunde, dass zum Detektieren von aufeinander folgenden Einheiten einer endlosen Bahn nicht unbedingt eigens dafür vorgesehene Markierungen angebracht werden müssen, sondern dass es vielmehr genügt, die ohnehin auf der Bahn vorhandenen, über die Länge der Bahn variierenden Eigenschaften sensorisch zu erfassen und in geeigneter Weise auszuwerten. Dabei kann man sich erfindungsgemäß insbesondere die Tatsache zunutze machen, dass sich die genannten Änderungen der Bahneigenschaften bei aufeinanderfolgenden Einheiten jeweils wiederholen, so dass die detektierten Änderungen jeweils genau einer Einheit der Bahn zugeordnet werden können. Durch diese Zuordnungsmöglichkeit können dementsprechend die aufeinanderfolgenden Einheiten einer Bahn erkannt werden. Da die sich ändernden Bahneigenschaften ferner einen konstanten Ortsbezug zu den Übergängen benachbarter Einheiten aufweisen, können diese Übergänge mit der erfindungsgemäßen Vorrichtung sowie mit dem erfindungsgemäßen Verfahren ebenfalls problemlos ermittelt werden, so dass beispielsweise an diesen Übergängen jeweils automatisch ein Schneidprozess auslösbar ist.The invention is therefore based on the surprising finding that for the detection of successive units of an endless web not necessarily dedicated markers must be attached, but that it is sufficient, the existing anyway on the web, varying over the length of the web properties sensorially to capture and evaluate in an appropriate manner. In this case, according to the invention, it is possible in particular to make use of the fact that the said changes in the web properties are repeated in successive units, so that the detected ones Changes can be assigned to exactly one unit of the train. As a result of this assignment possibility, the successive units of a web can be detected accordingly. Since the changing web properties also have a constant location reference to the transitions of adjacent units, these transitions can also be easily determined with the device according to the invention and with the method according to the invention, so that, for example, automatically a cutting process can be triggered at these transitions.
Bei üblichen Anwendungsfällen wiederholen sich die zu detektierenden Änderungen der Bahneigenschaften bei allen Einheiten der Bahn, so dass diese beispielsweise in lauter untereinander gleiche Einheiten zerschnitten werden kann. Es sind jedoch auch andere Anwendungsfälle denkbar, bei denen die sich wiederholenden Änderungen der Bahneigenschaften nicht bei allen Einheiten in gleicher Weise vorhanden sind. Beispielsweise ist es möglich, dass eine Bahn zwei unterschiedliche Arten von Einheiten aufweist, wobei jede dieser beiden Arten untereinander sich wiederholende Änderungen der Bahneigenschaften aufweisen, wobei sich jedoch die Änderungen der einen Art von den Änderungen der anderen Art unterscheiden. In diesem Fall kann dann erfindungsgemäß unterschieden werden, von welcher der beiden Arten die jeweils erkannte Einheit ist, woraufhin eine auf die jeweilige Art abgestimmte Bearbeitung ausgelöst werden kann.In customary applications, the changes to the web properties to be detected are repeated in all units of the web, so that they can be cut, for example, in noisy mutually identical units. However, there are also other applications conceivable in which the repetitive changes in the web properties are not present in all units in the same way. For example, it is possible for a web to have two different types of units, each of which has mutually repeating changes in web properties, but the changes of one type differ from the other type. In this case, it can then be distinguished according to the invention, of which of the two types is the respectively recognized unit, whereupon a matched to the respective type processing can be triggered.
Gemäß der Erfindung ist der Sensor zur Erkennung einer Abfolge von mehreren, voneinander verschiedenen Änderungen der Bahneigenschaften ausgelegt ist. Hierdurch wird es möglich, bezogen auf jede einzelne Einheit der Bahn zwei oder mehr Änderungen der Bahneigenschaften zu detektieren, was die Eindeutigkeit des Detektionsergebnisses erhöht. Wenn beispielsweise pro Einheit drei unterschiedliche Änderungen detektiert werden sollen, von denen die letzte Änderung beim Übergang auf die nachfolgende Einheit auftritt, kann erfindungsgemäß überprüft werden, ob zuerst die ersten beiden Änderungen erkannt wurden, woraufhin die dritte Änderung nur dann als Übergang zur nächsten Einheit gewertet wird, wenn zuvor die ersten beiden Änderungen korrekt erkannt wurden. Die Sicherheit und Zuverlässigkeit einer korrekten Erkennung lässt sich somit durch diese bevorzugte Erfindungsvariante deutlich erhöhen.According to the invention, the sensor is designed to detect a sequence of a plurality of mutually different changes in the web properties. This makes it possible to detect two or more changes in the web properties relative to each unit of the web, which increases the uniqueness of the detection result. If, for example, three different changes per unit are to be detected, of which the last change occurs during the transition to the subsequent unit, it can be checked according to the invention whether the first two changes were detected first, whereupon the third change only counts as a transition to the next unit if the first two changes were detected correctly before. The security and reliability of a correct recognition can thus be significantly increased by this preferred variant of the invention.
Erfindungsgemäß ist ein Speicher vorgesehen werden, in welchem eine chronologische Sollabfolge der pro Einheit zu detektierenden Änderungen speicherbar ist. Ferner ist eine Auswerteeinheit zum Vergleich der tatsächlich chronologisch detektierten Änderungsfolge mit der gespeicherten Sollabfolge vorgesehen, mit welcher überprüft wird, ob auch tatsächlich die erwartete Änderungsfolge detektiert und somit eine Einheit erkannt wurde. Im Fall der Übereinstimmung zwischen der gespeicherten Sollabfolge und der detektierten Änderungsfolge kann die Auswerteeinheit dann ein auf die erkannte Einheit bezogenes Detektionssignal abgeben.According to the invention, a memory is provided in which a chronological setpoint sequence of the changes to be detected per unit can be stored. Furthermore, an evaluation unit is provided for comparing the actually chronologically detected change sequence with the stored desired sequence, with which it is checked whether the expected change sequence was actually detected and thus a unit was recognized. In the case of the correspondence between the stored desired sequence and the detected change sequence, the evaluation unit can then emit a detection signal related to the detected unit.
Um bei dem genannten Vergleich zwischen Sollabfolge und tatsächlich detektierter Änderungsfolge hinsichtlich des Vergleichsergebnisses zusätzliche Sicherheit zu erreichen, können neben der Chronologie der Änderungen auch noch deren relative Zeitbezüge und/oder die jeweilige Art der Änderungen und/oder der jeweilige Grad der Änderungen berücksichtigt werden. Es wird in diesem Fall dann also untersucht, in welchem zeitlichen Bezug die detektierten Änderungen zueinander stehen und/oder welcher Art und von welcher Stärke die detektierten Änderungen waren.In order to obtain additional security with regard to the comparison result in the aforementioned comparison between the desired sequence and the actually detected change sequence, the relative time references and / or the respective type of changes and / or the respective degree of changes can be taken into account in addition to the chronology of the changes. In this case, it is then examined in which temporal relation the detected changes are related to each other and / or of which type and of which magnitude the detected changes were.
Alle auf eine Einheit detektierten Änderungen führen bevorzugt zur Abgabe lediglich eines einzigen Detektionssignals, welches eindeutig der jeweils detektierten Einheit zugeordnet werden kann. Dieses einzige Detektionssignal ist bevorzugt von einer Änderung mit vergleichsweise hohem Änderungsgrad abhängig, da eine solche Änderung, die beispielsweise als besonders markanter, scharfer Farbübergang ausgebildet sein kann, besonders gut vom Sensor zu erkennen ist. Wenn der Abstand zwischen dieser Änderung und dem Anfang oder dem Ende der jeweiligen Einheit bekannt ist, können Anfang und Ende der Einheit so mit einer besonders hohen Ortsauflösung erkannt werden, da die jeweilige Position einfach aus der Position der erkannten Änderung und dem bekannten Abstand berechenbar ist.All changes detected on one unit preferably lead to the delivery of only a single detection signal, which can be unambiguously assigned to the respectively detected unit. This single detection signal is preferably dependent on a change with a comparatively high degree of change, since such a change, which may be formed for example as a particularly striking, sharp color transition, can be recognized particularly well by the sensor. If the distance between this change and the beginning or the end of the respective unit is known, the start and end of the unit can be identified with a particularly high spatial resolution, since the respective position can be simply calculated from the position of the detected change and the known distance ,
Es kann ferner ein Verzögerungsglied zur Auslösung des Detektionssignals mit einer einstellbaren zeitlichen Verzögerung nach Erkennung der Übereinstimmung zwischen der gespeicherten Sollabfolge und der tatsächlich detektierten Änderungsfolge vorgesehen werden. Mit einem solchen Verzögerungsglied kann z.B. dem Umstand Rechnung getragen werden, dass sich eine Schneideinrichtung in Förderrichtung hinter dem erfindungsgemäßen Sensor befindet und somit nach der Detektion einer Einheit eine von der Fördergeschwindigkeit abhängige Zeit vergehen muss, bis sich die detektierte Einheit bzw. deren Anfang oder deren Ende im Bereich der Schneideinrichtung befindet. Das Verzögerungsglied kann somit z.B. exakt so eingestellt werden, dass in Abhängigkeit von den erfindungsgemäß detektierten Einheiten durch die Schneidvorrichtung immer exakt am Übergang zwischen zwei Einheiten ein Schnitt erfolgt. Ferner kann mit dem Verzögerungsglied berücksichtigt werden, wenn die letzte Detektion einer Änderung einer Einheit nicht am Ende der Einheit sondern bereits vorher erfolgt, so dass sich das Ende der Einheit bei Detektion der letzten Änderung noch nicht unterhalb des Sensors befindet. Das Verzögerungsglied wird dann in Abhängigkeit von der Fördergeschwindigkeit so eingestellt, dass die Verzögerungszeit oder zumindest eine Komponente derselben derjenigen Zeit entspricht, die benötigt wird, um die Einheit um den Abstand zwischen der letzten detektierten Änderung und dem Ende der Einheit weiter zu fördern. Das Verzögerungsglied kann natürlich auch so eingestellt werden, dass zum einen die letztgenannte Verzögerung und zum anderen zusätzlich der bereits erwähnte Abstand zwischen dem Sensor und einer Schneidvorrichtung berücksichtigt wird.A delay element may also be provided for triggering the detection signal with an adjustable time delay after detection of the correspondence between the stored desired sequence and the actually detected change sequence. With such a delay element can be taken into account, for example, the fact that a cutting device is behind the sensor according to the invention in the conveying direction and thus must depend on the detection of a unit dependent on the delivery speed time until the detected unit or its beginning or the End is located in the area of the cutting device. The delay element can thus be set, for example, exactly so that, depending on the units detected according to the invention, a cut always takes place exactly at the transition between two units by the cutting device. Furthermore, it can be considered with the delay element, if the last detection of a change in a unit not at the end of the unit but already before, so that the end of the unit is not yet below the sensor at detection of the last change. The delay element is then adjusted in dependence on the conveying speed such that the delay time or at least a component thereof corresponds to the time required to further convey the unit by the distance between the last detected change and the end of the unit. Of course, the delay element can also be adjusted so that, on the one hand, the latter delay and, on the other hand, the already mentioned distance between the sensor and a cutting device is taken into account.
Die durch das Verzögerungsglied bewirkten Verzögerungszeiten müssen nicht zwangsläufig konstant sein. Vielmehr können sie an die jeweiligen Fördergeschwindigkeiten angepasst werden. Insbesondere kann aber auch eine Änderung der Verzögerungszeiten während des Förderprozesses einer einzelnen Bahn stattfinden, wenn diese Bahn zu unterschiedlichen Zeiten mit unterschiedlichen Geschwindigkeiten gefördert wird.The delay times caused by the delay element do not necessarily have to be constant. Rather, they can be adapted to the respective conveying speeds. In particular, however, a change in the delay times during the conveying process of a single web can take place, if this web is conveyed at different times at different speeds.
Alternativ zur Verwendung eines Verzögerungsgliedes mit einstellbarer Verzögerungszeit kann bei konstanter Fördergeschwindigkeit auch eine konstante Verzögerungszeit gegeben sein, da in diesem Fall beispielsweise der Sensor einfach im Rahmen eines Teachvorganges solange entlang der Förderstrecke verschoben werden kann, bis z.B. ein vom Sensor ausgelöster Scheidvorgang immer exakt an den Übergängen zwischen zwei Einheiten erfolgt.Alternatively to the use of a delay element with adjustable delay time, a constant delay time can also be given at a constant conveying speed, since in this case, for example, the sensor can simply be displaced along the conveying path as part of a teaching operation, until e.g. a separation process initiated by the sensor always takes place exactly at the transitions between two units.
Bei bekannter Fördergeschwindigkeit kann aus den detektierten Änderungen auf die Länge von Farbelementen, die sich auf der Bahn befinden, geschlossen werden. Anfang und Ende solcher Farbelemente werden als erfindungsgemäße Änderungen detektiert, und aus der zwischen diesen Detektionsvorgängen verstrichenen Zeit kann dann unter Berücksichtigung der Fördergeschwindigkeit die Länge eines Farbelements berechnet und gespeichert werden. Weiterhin kann die so berechnete Länge der Farbelemente dann als Erkennungsmerkmal für aufeinander folgende Einheiten herangezogen werden, indem bei jeder Einheit der Bahn überprüft wird, ob die der jeweiligen Einheit zugeordneten Farbelemente die bei vorhergehenden Einheiten ermittelte Länge besitzen.With known conveying speed can be closed from the detected changes on the length of color elements, which are located on the web. The beginning and the end of such color elements are detected as changes according to the invention, and the time elapsed between these detection operations can then be considered the conveying speed the length of a color element is calculated and stored. Furthermore, the length of the color elements calculated in this way can then be used as a recognition feature for successive units by checking on each unit of the web whether the color elements assigned to the respective unit have the length determined in previous units.
Wenn andererseits die Fördergeschwindigkeit nur im Rahmen einer Einlernphase bekannt und im weiteren Betrieb nicht mehr bekannt ist, kann die im normalen Betrieb jeweils ermittelte Länge eines Farbelements dazu herangezogen werden, die momentan gerade vorhandene relative Fördergeschwindigkeit zu berechnen. Beispielsweise kann im Rahmen des Einlernvorgangs eine normierte Fördergeschwindigkeit von 1 vorhanden sein, bei der als Länge eines Farbelements beispielsweise der ebenfalls normierte Wert 1 ermittelt wird. Wenn nun im auf die Einlernphase folgenden Normalbetrieb der Anlage eine Länge des Farbelements von 2 detektiert wird, kann davon ausgegangen werden, dass die momentane Fördergeschwindigkeit - ebenfalls normiert - 0,5 beträgt.If, on the other hand, the conveying speed is known only during a training phase and is no longer known during further operation, the length of a color element determined in normal operation can be used to calculate the currently present relative conveying speed. For example, a normalized conveying speed of 1 may be present within the scope of the teaching process, in which the value of 1, which is also normalized, is determined as the length of a color element, for example. If a length of the color element of 2 is now detected in the normal operation of the system following the training phase, it can be assumed that the instantaneous conveying speed-also normalized-is 0.5.
Der erfindungsgemäß eingesetzte Sensor zur Erkennung der Änderungen der Bahneigenschaften kann so ausgelegt werden, dass er Änderungen der Farbe, des Kontrastes, des Reflexionsvermögens und/oder sonstiger Oberflächenbeschaffenheiten der Bahn erkennen kann. Es können also zur Realisierung des erfindungsgemäßen Gedankens unterschiedliche Arten von Änderungen der Bahneigenschaften herangezogen werden, wobei z.B. auch aus mehreren Sensoren bestehende Sensoranordnungen eingesetzt werden können, die gleichzeitig verschiedene Arten von Änderungen detektieren können. Es ist also durchaus möglich, eine einzelne Einheit zu detektieren, indem aufeinanderfolgende Änderungen der Bahneigenschaften unterschiedlicher Art detektiert werden. Grundsätzlich wird man immer diejenigen Arten von Änderungen für die Auswertung heranziehen, mit denen die amplitudenmäßig größten Sensorsignale erzeugbar sind, da auf diese Weise das Risiko von Fehldetektionen minimiert wird.The sensor for detecting the changes in web properties used according to the invention can be designed so that it can detect changes in the color, the contrast, the reflectivity and / or other surface textures of the web. Different types of changes in the web properties can thus be used to implement the inventive concept, whereby, for example, sensor arrangements consisting of a plurality of sensors can also be used, which can simultaneously detect different types of changes. It is therefore quite possible to detect a single unit by detecting successive changes in the web properties of different types. Basically you will always use those types of changes for the evaluation, with which the amplitude-wise largest sensor signals can be generated, since in this way the risk of misdetections is minimized.
In einer bevorzugten Ausführungsform kann der Sensor als Kontrasttaster ausgebildet werden, welcher die Bahn mit unterschiedlichen Sendefarben beleuchten kann. In diesem Fall kann dann in Abhängigkeit von der Farbe der zu detektierenden Änderungen während des Abtastens jeder Einheit die Sendefarbe derart verändert werden, dass sich ein jeweils maximaler Kontrastwert einstellt.In a preferred embodiment, the sensor can be designed as a contrast scanner, which can illuminate the web with different transmission colors. In this case, depending on the color of the changes to be detected during the scanning of each unit, the transmission color can then be changed such that a respective maximum contrast value is established.
Bei der erfindungsgemäß untersuchten Bahn kann es sich um eine bedruckte oder unbedruckte Papierbahn handeln. Bei der Verarbeitung von bedruckten Papierbahnen kann die auf der Bahn befindliche Druckfarbe die erfindungsgemäß auszuwertenden Kontrastsprünge auslösen.The web investigated according to the invention may be a printed or unprinted paper web. During the processing of printed paper webs, the printing ink present on the web can trigger the contrast jumps to be evaluated according to the invention.
Weitere bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben.Further preferred embodiments of the invention are described in the subclaims.

In
Die Papierbahn 1 besteht dabei aus aneinander angrenzenden, untereinander gleichen Einheiten 10. Der Übergang zwischen zwei aneinander angrenzenden Einheiten ist in
Aus
Oberhalb der Bahn 1 ist ein Sensor 4 angeordnet, welcher als Kontrasttaster ausgebildet ist, der die Bahn 4 mit unterschiedlichen Farben beleuchten kann. In Förderrichtung beabstandet vom Sensor 4 ist eine Schneidvorrichtung 5 vorgesehen, mittels welcher die Bahn 1 senkrecht zur Förderrichtung A geschnitten werden kann.Above the web 1, a sensor 4 is arranged, which is designed as a contrast sensor, which can illuminate the web 4 with different colors. In the conveying direction spaced from the sensor 4, a cutting device 5 is provided, by means of which the web 1 can be cut perpendicular to the conveying direction A.
Sensor 4 sowie Schneidvorrichtung 5 sind über Daten und Steuerleitungen mit einer Auswerteeinheit 6 gekoppelt, welche Daten vom Sensor 4 empfängt und verarbeitet sowie weiterhin dazu in der Lage ist, den Sensor 4 und die Schneidvorrichtung 5 anzusteuern.Sensor 4 and cutting device 5 are coupled via data and control lines to an
Ein Blockschaltbild der Auswerteeinheit 6 gemäß
Zentraler Bestandteil dieser Auswerteeinheit 6 ist die Recheneinheit 7, welche beispielsweise als handelsüblicher Mikroprozessor ausgebildet werden kann. Über eine Schnittstelle A empfängt die Recheneinheit 7 Signale vom Sensor 4, über eine Schnittstelle B kann die Recheneinheit 7 den Sensor 4 ansteuern. Über eine Schnittstelle C erhält die Recheneinheit 7 Informationen hinsichtlich der aktuellen Fördergeschwindigkeit der Bahn 1.The central component of this
Die Recheneinheit 7 kommuniziert mit einem Speicher 8, in welchem eine chronologische Sollabfolge der vom Sensor 4 zu detektierenden Farbänderungen speicherbar ist.The arithmetic unit 7 communicates with a memory 8, in which a chronological setpoint sequence of the color changes to be detected by the sensor 4 can be stored.
Die Recheneinheit 7 beaufschlagt eine Verzögerungseinheit 9, deren Verzögerungszeit Δt über die Recheneinheit 7 variabel einstellbar ist. Der Ausgang der Verzögerungseinheit 9 wird an eine Schnittstelle D geführt, welche mit der Schneidvorrichtung 5 verbunden ist und bei Abgabe eines Signals über die Schnittstelle D einen Schneidvorgang auslöst.The arithmetic unit 7 acts on a delay unit 9 whose delay time .DELTA.t is variably adjustable via the arithmetic unit 7. The output of the delay unit 9 is fed to an interface D, which is connected to the cutting device 5 and triggers a cutting operation upon the delivery of a signal via the interface D.
Beim Betrieb der Anordnung gemäß den
Beim tatsächlichen Betrieb der Anordnung liefert der Sensor 4 dann jeweils Änderungssignale, wenn jeweils Anfang und Ende der Aufdrucke 2, 3 am Sensor vorbeigeführt werden. Diese Daten werden der Recheneinheit 7 über die Schnittstelle A zugeführt, woraufhin die Recheneinheit 7 diese Daten mit den im Speicher 8 abgelegten Werten vergleicht. Wenn die Recheneinheit 7 im Rahmen einer Echtzeitverarbeitung feststellt, dass die Abfolge der detektierten Änderungen mit der im Speicher 8 abgelegten Abfolge übereinstimmt, kann davon ausgegangen werden, dass sich nach dem Erkennen des dann zu erwartenden hinteren Endes des Aufdrucks 2, welches den markantesten Farbübergang darstellt, dieses hintere Ende des Aufdrucks 2 gerade unterhalb des Sensors 4 befindet. Bei konstanter Fördergeschwindigkeit kann die Recheneinheit 7 aus dem bekannten Abstand zwischen Sensor 4 und Schneidvorrichtung 5 und dem genannten Abstand d genau berechnen, nach welcher Verzögerungszeit der Übergang 11, welcher dem Ende des detektierten Aufdrucks 2 folgt, unterhalb der Schneidvorrichtung 5 zu liegen kommt. Nach Verstreichen einer entsprechenden Verzögerungszeit Δt, welche durch das Verzögerungsglied 9 bewirkt wird, wird dann über die Schnittstelle D ein Schaltsignal an die Schneidvorrichtung ausgegeben, welche einen Schneidvorgang entlang des Übergangs 11 auslöst. Wenn sich die Fördergeschwindigkeit ändert, kann die Recheneinheit 7 eine entsprechend angepasste Verzögerungszeit Δt berechnen, welche dann von der Recheneinheit 7 dem Verzögerungsglied 9 zur Verfügung gestellt wird.During actual operation of the arrangement, the sensor 4 then provides change signals each time the beginning and end of the imprints 2, 3 are passed past the sensor. These data are supplied to the arithmetic unit 7 via the interface A, whereupon the arithmetic unit 7 compares these data with the values stored in the memory 8. If the computing unit 7 determines in the context of a real-time processing that the sequence of detected changes coincides with the sequence stored in the memory 8, it can be assumed that after recognizing the then expected rear end of the imprint 2, which represents the most striking color transition , this rear end of the imprint 2 is just below the sensor 4. At a constant conveying speed, the arithmetic unit 7 can accurately calculate from the known distance between sensor 4 and cutting device 5 and said distance d, after which delay time the transition 11, which follows the end of the detected imprint 2, comes to lie below the cutting device 5. After elapse of a corresponding delay time .DELTA.t, which is effected by the delay element 9, then a switching signal is output via the interface D to the cutting device, which triggers a cutting process along the transition 11. If the conveying speed changes, the arithmetic unit 7 can calculate a correspondingly adapted delay time Δt, which is then made available to the delay element 9 by the arithmetic unit 7.
Im Rahmen des vorstehend erwähnten Teach-Prozesses kann ferner überprüft werden, mit welcher Farbe die Bahn 1 vom Sensor 4 beleuchtet werden muss, damit Kontrastübergänge der Aufdrucke 2, 3 besonders gut erkennbar sind. Beispielsweise kann es sinnvoll sein, Anfang und Ende des Aufdrucks 2 mit der Beleuchtungsfarbe grün und Anfang und Ende des Aufdrucks 3 mit der Beleuchtungsfarbe blau zu erkennen. Ein Umschalten der Beleuchtungsfarbe währen des Abtastens einer Einheit 10 kann dabei wiederum von der Recheneinheit 7, beispielsweise über die Schnittstelle B gemäß
