Description

Die Erfindung betrifft eine Vorrichtung zur Kontrolle der Heftung von Produkten mittels einer Drahtheftvorrichtung.The invention relates to a device for controlling the Stapling products using a wire stapler.

Vorrichtungen dieser Art sind beispielsweise bei Sammelheftern bekannt. Sie dienen dazu, die Anzahl der Heftungen zu kontrollieren. Diese Vorrichtungen weisen einen Metalldetektor auf, der beispielsweise induktiv das Vorhandensein einer Heftklammer an einem Druckprodukt, beispielsweise einer Broschüre feststellt. Der Metalldetektor ist in Transportrichtung gesehen nach der Drahtheftvorrichtung über einer Fördereinrichtung bzw. einer Sammelkette angeordnet. Jede durchlaufende Heftklammer löst einen Impuls aus. Wird aufgrund einer Störung der Drahtheftvorrichtung nicht geheftet, so kann dies sofort ermittelt und entsprechend ein Signal an die Maschinensteuerung abgegeben werden. Die verwendeten Metalldetektoren besitzen einen vergleichsweise kurzen Bereich. Dies führt dann zu Schwierigkeiten, wenn abwechselnd Drahtklammern mit und ohne Öse verwendet werden. Für beide Arten der Heftklammern kann der Metalldetektor nicht optimal eingestellt werden. In einem Fall ist er zu nahe bei der Klammer und im anderen Fall zu weit weg.Devices of this type are, for example, in saddlestitchers known. They serve to increase the number of stitches check. These devices have a metal detector on, for example, inductively the presence of a Staple on a printed product, such as a brochure notes. The metal detector is in the transport direction seen after the wire stapler above a conveyor or a collection chain arranged. Any continuous Staple triggers an impulse. Is due to a Malfunction of the wire stapling device is not stapled this is determined immediately and a signal sent to the machine control be delivered. The metal detectors used have a comparatively short range. This leads to difficulties when alternately wire clips can be used with and without eyelet. For both types of staples the metal detector cannot be set optimally become. In one case it is too close to the bracket and in the other case too far away.

Ueberdies können Induktionsmessungen zusätzlich durch metallische Einlagen in den Druckprodukten beeinflusst werden.In addition, induction measurements can also be carried out using metallic Deposits in the printed products can be influenced.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Gattung zu schaffen, die auch bei unterschiedlichen Drahtklammern eine zuverlässige Kontrolle der Heftung von Produkten gewährleistet und die dennoch funktionssicher ist und kostengünstig hergestellt werden kann.The invention has for its object a device to create the above-mentioned genus, even with different Wire clips a reliable control of the stapling guaranteed by products and yet functionally reliable is and can be produced inexpensively.

Die Aufgabe ist bei einer gattungsgemässen Vorrichtung dadurch gelöst, dass an der Drahtheftvorrichtung Messmittel angeordnet sind, mit denen während einer Heftung Zustandsänderungen der Drahtheftvorrichtung ermittelt und mit vorgegebenen Werten verglichen werden.The task is in a generic device solved that measuring devices arranged on the wire stapling device with which changes in state during a stapling the wire stitching device determined and with predetermined Values are compared.

Der Erfindung liegt die Erkenntnis zugrunde, dass Störungen beim Heftvorgang unterschiedliche Zustandsänderungen, insbesondere unterschiedliche Krafteinwirkungen auf die Drahtheftvorrichtung bewirken. Fehlt beispielsweise ein Klammerrohling bei der Einleitung eines Heftvorganges oder ist bei einem solchen Rohling ein Klammerschenkel zu kurz, so sind insbesondere am Umbiegerstössel die Krafteinwirkungen beim Umbiegen der Drahtklammer wesentlich verschieden von den Einwirkungen während einer korrekten Heftung. Wird beispielsweise ein Rohling mit einem zu kurzen Klammerschenkel geheftet, so ist die Krafteinwirkung auf den Umbiegerstössel im zeitlichen Verlauf wesentlich verschieden von diesem Verlauf bei einer korrekten Heftung. Solche Krafteinwirkungen auf den Umbiegerstössel verursachen an diesem eine Stauchung, die beispiels weise mit einem Dehnmessstreifen oder Piezokristall festgestellt werden kann. Abweichungen können durch einen Vergleich mit einer über eine bestimmte Wegstrecke oder Zeitraum ermittelten Kurve verglichen werden.The invention is based on the finding that interference different state changes during the stapling process, in particular different forces acting on the wire stitching device cause. For example, a blank bracket is missing when initiating a stapling process or is at one such a blank a bracket leg too short, in particular on the bending ram the force effects when bending the wire clip significantly different from the actions during correct stapling. For example a blank stapled with a too short clip leg, so is the force acting on the bending ram in time Course significantly different from this course in one correct stapling. Such forces on the bending ram cause a compression on this, for example ascertained with a strain gauge or piezo crystal can be. Deviations can be compared with a determined over a certain distance or period Curve can be compared.

Ein wesentlicher Vorteil der erfindungsgemässen Vorrichtung wird darin gesehen, dass die Heftungen nicht nur lediglich gezählt und fehlende Heftklammern festgestellt werden können, sondern auch andere Abweichungen von einer korrekten Heftung feststellbar sind. Störungen in der Heftung können somit sehr schnell festgestellt und damit ein unnötiger Materialverbrauch vermieden werden.A major advantage of the device according to the invention is seen in that the stitching is not just counted and missing staples can be found, but also other deviations from correct stapling are noticeable. Faults in the stitching can be very bad quickly determined and thus unnecessary material consumption be avoided.

Vorzugsweise werden Zustandsänderungen des Umbiegerstössels der Drahtheftvorrichtung ermittelt. Diese Zustandsänderungen sind besonders charakteristisch für das Umbiegen bzw. Umbiegen der Klammerschenkel, was einen wesentlichen Schritt bei einer Heftung bedeutet.Changes in state of the bending ram are preferred the wire stitching device determined. These state changes are particularly characteristic of bending or bending the staple leg, which is an essential step in a stitch means.

Die erfindungsgemässe Vorrichtung kann dann besonders kostengünstig realisiert werden, wenn gemäss einer Weiterbildung der Erfindung das Messmittel einen Dehnmessstreifen oder einen Piezokristall aufweist. Der Dehnmessstreifen wird vorzugsweise auf den Umbiegerstössel aufgeklebt. Krafteinwirkungen auf den Stössel, bzw. Längenänderungen am Stössel während des Heftvorganges oder eines Teils des Heftvorganges können ermittelt und mit einer Kurve verglichen werden.The device according to the invention can then be particularly cost-effective can be realized if according to further training the invention, the measuring means a strain gauge or Piezo crystal has. The strain gauge is preferred glued to the bending ram. Effects of force on the ram, or changes in length on the ram during of the stapling process or part of the stapling process determined and compared with a curve.

Die erfindungsgemässe Vorrichtung ist für alle Arten von Drahtklammern verwendbar. Sie eignen sich insbesondere für alle bekannten Sammelhefter mit einer Drahtheftvorrichtung,-ob Längs- oder Querförderung der Druckprodukte-, welche einen oder mehrere Heftköpfe aufweist. The device according to the invention is for all types of Wire clips can be used. They are particularly suitable for all known saddle stitchers with a wire stitching device, whether Longitudinal or transverse conveyance of the printed products, which one or has several stitching heads.

Die in Figur 1 gezeigte Drahtheftvorrichtung 1 weist einen Heftkopf 4 sowie einen Umbieger 3 auf, die wie üblich ausgebildet sein können und mit denen in bekannter Weise ein Heftvorgang durchführbar ist. Dieser Heftvorgang umfasst in üblicher Weise das Zuführen eines Drahtes, das Abschneiden eines Rohlings, die Klammerformung, das Durchstechen des zu heftenden Produktes 2 und das Umbiegen der beiden Klammerschenkel 16. In der Figur 1 ist das Produkt 2 mit der Drahtklammer 15 geheftet, der Heftvorgang ist hier somit abgeschlossen. Die Heftung des Produktes 2 kann beispielsweise eine Seitenheftung oder eine Heftung an einem Falz eines Druckproduktes sein. Es sind auch andere Heftungen denkbar. Der Heftkopf 4 weist hier üblicherweise einen Treiber und einen Bieger auf, die hier nicht gezeigt sind. Ebenfalls nicht gezeigt ist die an sich gut bekannte Zuführung des Drahtes. Der Umbieger 3 weist einen Tisch 5 auf, an dem zwei Schenkelbieger 6 gelagert sind, die zum Umbiegen der beiden Klammerschenkel 16 in Richtung der Pfeile 18 mittels des Umbiegerstössels 7 verschwenkbar sind. Die Figuren 4 bis 6 zeigen das Umbiegen der beiden Klammerschenkel 16 mit den beiden Schenkelbiegern 6, die mit einem Hub des Umbiegerstössels 7 in Richtung des Pfeils 19 verschwenkt werden. Mit dem Umbiegerstössel 7 wird den beiden Schenkelbiegern 6 somit die Kraft zugeführt, die zum Umbiegen der beiden Klammerschenkel 16 erforderlich ist. Wird bei einer Störung der Klammerrohling nicht durch das Produkt 2 hindurchgestossen, so ist der Kraftaufwand am Umbiegerstössel 7 entsprechend wesentlich kleiner. Auch andere Störungen, beispielsweise zu kurze Klammerschenkel 16 führen zu einem entsprechend kleineren oder grösseren Kraftaufwand des Umbiegerstössels 7.The wire stitching device 1 shown in FIG. 1 has one Stapling head 4 and a bender 3, which are formed as usual can be and with which a stapling process in a known manner is feasible. This stapling process usually includes Way of feeding a wire, cutting off one Blank, the staple formation, the piercing of the staple Product 2 and the bending of the two clamp legs 16. In FIG. 1, the product 2 is with the wire clip 15 stapled, the stapling process is completed here. The Stapling of the product 2 can, for example, a side stapling or a stitch on a fold of a printed product his. Other staplings are also possible. The stapling head 4 usually has a driver and a bender here, that are not shown here. The is also not shown well-known feeding of the wire. The bender 3 has a table 5 on which two leg benders 6 are mounted are for bending the two clamp legs 16 in Direction of arrows 18 can be pivoted by means of the bending plunger 7 are. Figures 4 to 6 show the bending of the two clamp legs 16 with the two leg benders 6, which with a stroke of the bending ram 7 in the direction of Arrow 19 are pivoted. With the bending ram 7 the two leg benders 6 thus supplied the force that for bending the two clamp legs 16 is required. If the staple blank is not disturbed by the If product 2 is pushed through, the force on the bending plunger is 7 correspondingly much smaller. Others too Faults, for example, lead to short clip legs 16 for a correspondingly smaller or greater effort of the bending ram 7.

Um solche Abweichungen von der Umbiegekraftübertragung zu ermitteln, ist auf den Umbiegerstössel 7 ein Dehnmessstreifen 9 oder ein anderes geeignetes Messelement angeordnet. Mit diesem Dehnmessstreifen 9 können Stauchungen am Umbiegerstössel 7 ermittelt werden. Solche Stauchungen des Umbiegerstössels 7 stehen in einem bestimmten Verhältnis zur Kraft, welche der Umbiegerstössel 7 auf die beiden Schenkelbieger 6 ausübt. Der Dehnmessstreifen 9 kann auch ein anderer Kraftsensor sein, beispielsweise ein Piezokristall. Grundsätzlich sind aber auch andere Sensoren denkbar, die beispielsweise auf Temperatur- oder andere Zustandsänderungen ansprechen. Während der Kraftausübung wird der Umbiegerstössel 7 in Richtung des Pfeiles 19 vertikal nach oben bewegt. Der hier nicht gezeigte an sich bekannte Antriebsmechanismus ist in einem Gestell 21 angeordnet. Weist die Drahtheftvorrichtung 1 wie üblich zwei oder mehr Heftköpfe 4 und Umbieger 3 auf, so ist an jedem Umbiegerstössel 7 ein Dehnmessstreifen 9 oder ein anderes Messelement angebracht.In order to determine such deviations from the bending force transmission, is a strain gauge 9 on the bending ram 7 or another suitable measuring element. With this Strain gauges 9 can compress on the bending ram 7 can be determined. Such upsetting of the bending ram 7 are in a certain relationship to the force which the Bending ram 7 exerts on the two leg benders 6. The Strain gauge 9 can also be another force sensor, for example a piezo crystal. Basically, however other sensors are also conceivable, which, for example, or address other changes in condition. During the The bending ram 7 is exerted in the direction of the force Arrow 19 moved vertically upwards. The one not shown here drive mechanism known per se is in a frame 21 arranged. Has the wire stapler 1 as usual two or more stitching heads 4 and bender 3, so is on each bender 7 a strain gauge 9 or another measuring element appropriate.

Der Dehnmessstreifen 9 ist gemäss Figur 2 über eine Signalleitung 10 mit einer Messauswertvorrichtung 8 verbunden. Die Messung erfolgt über einen vorbestimmten Zeitraum oder Weg. Dieser wird beispielsweise mit einem Drehgeber 12 bestimmt. Die Messung erfolgt also beispielsweise während eines vorgegebenen Hubes des Umbiegerstössels 7. Die Messung über diesen Weg ergibt eine Kurve, die beispielhaft in Figur 3 gezeigt ist. Bei korrekten Heftungen ist der Verlauf dieser Kurve F innerhalb einer Bandbreite, welche durch die beiden Kurven F1 und F2 angedeutet ist, im wesentlichen gleich. Die Kurve F für eine korrekte Heftung kann empirisch ermittelt und in der Messauswertvorrichtung 8 gespeichert werden. Es können auch mehrere solche Kurven F ermittelt und gespeichert werden, wenn beispielsweise unterschiedliche Drähte verwendet werden.The strain gauge 9 is according to Figure 2 via a signal line 10 connected to a measurement evaluation device 8. The Measurement takes place over a predetermined period of time or distance. This is determined, for example, with a rotary encoder 12. The measurement is therefore carried out, for example, during a predetermined one Stroke of the bending ram 7. The measurement over this Weg results in a curve, which is shown by way of example in FIG. 3 is. With correct stapling, the course of this curve is F within a range defined by the two curves F1 and F2 is indicated, essentially the same. The curve F for correct stapling can be determined empirically and in the Measurement evaluation device 8 are stored. It can too several such curves F are determined and stored, if, for example, different wires are used.

Bei jeder Heftung werden in der Messauswertvorrichtung 8 die an dem Messstreifen 9 ermittelten Werte mit denen der Vergleichskurve F ermittelt. Liegen sämtliche ermittelten Werte im Bereich zwischen den beiden Kurven F1 und F2, so bewertet diese Messwertausrichtung die Heftung als korrekt und gibt ein entsprechendes Signal an eine Maschinensteuerung 14 ab. Ergeben jedoch die gemessenen Werte einen stark abweichenden Verlauf, wie dies in Figur 3 beispielsweise durch die gestrichelte Kurve F' angedeutet ist, so bewertet die Messauswertvorrichtung 8 die entsprechende Heftung als nicht korrekt und gibt über die Leitung 13 der Maschinensteuerung 14 ein Signal zur Unterbrechung des Heftvorganges. Die unkorrekte Heftung kann auch an einer Anzeige 20 angezeigt werden.With each stapling, the values determined on the measuring strip 9 with those of the comparison curve F determined. Are all determined values in the area between the two curves F1 and F2 this alignment of measurement values as correct and gives the staple a corresponding signal to a machine controller 14. However, the measured values give a very different result Course, as shown in Figure 3 by the dashed line Curve F 'is indicated, the evaluation device evaluates 8 the appropriate stapling is incorrect and gives a signal via line 13 to machine control 14 to interrupt the stitching process. The incorrect stitch can also be shown on a display 20.

Die in Figur 3 gezeigte Kurve F gibt vorzugsweise den Umbiegevorgang wieder. Dieser beginnt nach dem Durchstechen des Produktes 2 und endet nach dem Umbiegen der beiden Klammerschenkel 16. Grundsätzlich kann aber die Kurve F auch den gesamten Heftvorgang oder einen anderen Arbeitsschritt während einer Heftung umfassen.Curve F shown in FIG. 3 preferably indicates the bending process again. This begins after piercing the Product 2 and ends after bending the two clamp legs 16. In principle, however, curve F can also cover the entire Stapling or any other step during of a stitch.
