Abstract

The closing process involves the use of a clip device (1) with a drive (2, 3) and control (4), which also has a measuring device (9) on the holder (7, 17) of one of the clip closing tools. This measures the force acting between the first and second tools. The result of this measurement is then compared with a boundary value, and the control acts on the drive accordingly.

Description

Die Erfindung betrifft ein Verfahren zum Verschließen von wurstförmigen Verpackungshüllen mittels Clipsen gemäss Oberbegriff des Anspruchs 1. Ferner betrifft die Erfindung eine Clipvorrichtung zum Verschliessen von wurstförmigen Verpackungshüllen gemäss Oberbegriff des Anspruchs 9.The invention relates to a method for closing sausage-shaped packaging envelopes by means of clips according to the preamble of claim 1. Furthermore, the invention relates to a clip device for closing sausage-shaped packaging envelopes according to the preamble of claim 9.

Das Verschliessen von Würsten mittels Clipsen aus Draht in sogenannte Clipmaschinen ist bekannt. In der schlauchförmigen Verpackungshülle bzw. dem Darm wird dabei vom Verdrängerscheren ein füllgutfreier Bereich geschaffen, in dem die Clipse gesetzt werden (der Endclip der vorlaufenden Wurst und der Anfangsclip der folgenden Wurst). Der Verschluss der Clipse erfolgt durch ein Oberwerkzeug (Stempel) und ein Unterwerkzeug (Matrize), wel-, che den Clip fertig formen bzw. schliessen. Bedingt durch verschiedene Wurstarten werden unterschiedliche Clips verwendet, die sich sowohl in der Art und der Grösse unterscheiden. Dies bedingt den Wechsel der Werkzeuge an der Clipmaschine und oftmals auch des Arbeitshubes für das Schliessen der Clips, was gelegentlich zu Fehlmanipulationen führt, die zu einer Beschädigung des Werkzeuges und der Clipmaschine führen können. In der EP-A-0 467 020 wird eine hydraulische Anordnung vorgeschlagen, die ein Ausweichen des Stempels ermöglicht, wenn der Schliessdruck am Stempel überschritten wird. Diese Anordnung hat sich bewährt. Sie kann allerdings ihrerseits schadhaft werden, wenn die Bedienungsperson der Clipmaschine die Clipverschlusshöhe nicht korrekt einstellt und diese Einstellung auch bei Auslösung der Anordnung nicht korrigiert, so dass die Clipmaschine ständig im Auslösebereich dieser Anordnung betrieben wird. Dieses Dokument erwähnt auch das Abstellen der Maschine, wenn ein Solldruckwert überschritten wird. US-A-6 298 635 und US-A-3 913 628 zeigen ebenfalls gattungsgemässe Clipvorrichtungen. EP-A-1 731 432 zeigt ein Vorgehen mit drei Messwertbereichen für die Verschlusskraftmessung.The closing of sausages by means of clips made of wire in so-called clip machines is known. In the tubular packaging casing or the intestine of the displacement shears a Füllgutfreier area is created in which the clips are set (the Endclip the leading sausage and the initial clip of the following sausage). The clips are closed by an upper tool (punch) and a lower tool (die), which form or close the clip. Due to different types of sausages different clips are used, which differ in both the type and the size. This requires the change of tools on the clip machine and often also the working stroke for the closing of the clips, which occasionally leads to incorrect manipulation, which can lead to damage of the tool and the clip machine. In the EP-A-0 467 020 a hydraulic arrangement is proposed, which allows a deflection of the punch, when the closing pressure is exceeded on the punch. This arrangement has proven itself. However, it may in turn become defective if the operator of the clip machine does not adjust the clip closure height correctly and does not correct this setting even when the arrangement is triggered, so that the clip machine is constantly operated in the trigger region of this arrangement. This document also mentions stopping the machine when a set pressure value is exceeded. US-A-6 298 635 and US-A-3,913,628 also show generic clip devices. EP-A-1 731 432 shows a procedure with three measured value ranges for the shutter force measurement.

Der Erfindung liegt die Aufgabe zu Grunde ein verbessertes Verschliessverfahren bzw. eine verbesserte Clipvorrichtung zu schaffen.The invention is based on the object to provide an improved closure method or an improved clip device.

Dies wird mit dem Verfahren mit den kennzeichnenden Merkmalen des Anspruchs 1 und der Clipvorrichtung mit den kennzeichnenden Merkmalen des Anspruchs 9 erzielt.This is achieved with the method having the characterizing features of claim 1 and the clip device with the characterizing features of claim 9.

Dadurch, dass die zwischen den werkzeugen wirkende Kraft gemessen wird, kann durch den folgenden Grenzwertvergleich festgestellt werden, dass die Clipmaschine in einem Kraftbereich arbeitet, der unvorteilhaft oder gar unzulässig ist und durch das Einwirken auf den Antrieb kann ein weiterer Betrieb in einem unvorteilhaften oder unzulässigen Kraftbereich vermieden werden. Es ist ein Grenzwert für die gemessene Schliesskraft vorgesehen, bei dessen Erreichten oder gegebenenfalls Überschreiten der angefangene Clipschliessvorgang noch zu Ende geführt wird, da dies noch ohne Gefahr für die Werkzeuge oder die Clipmaschine zulässig ist. Es wird aber nach dem Abschluss des Clipschliessvorganges die Clipmaschine gestoppt. Dies erfolgt vorzugsweise in einer Stellung, die der Bedienungsperson die Änderung der Werkzeughöhe (Clipverschlusshöhe) erlaubt und es wird auch bevorzugterweise eine entsprechende Fehlermeldung angezeigt. Es ist ein weiterer (höherer) Grenzwert vorgesehen, bei dessen Erreichen der Antrieb sofort gestoppt wird und vorzugsweise auch um einen gewissen Antriebsdrehwinkel zurückgefahren wird; um die Werkzeuge und weitere Maschinenteile zu entlasten. Insbesondere mit elektrischen Servoantrieben ist eine entsprechend rasche Reaktion auf die Kraftmessung bzw. Grenzwerterreichung oder Grenzwertüberschreitung ohne weiteres möglich.Characterized in that the force acting between the tools is measured, it can be determined by the following limit comparison that the clipper operates in a force range that is unfavorable or even inadmissible and by acting on the drive, a further operation in a unfavorable or unauthorized Force range can be avoided. There is provided a limit value for the measured closing force, in the course of which the clip closing process which has already been achieved or, if applicable, exceeded, is still completed, since this is still permissible without risk for the tools or the clip machine. But it is stopped after the completion of the Clipschliessvorganges the clipper. This is preferably done in a position that allows the operator to change the tool height (clip closure height) and it is also preferably a corresponding error message displayed. There is another (higher) limit provided, when it reaches the drive is stopped immediately and preferably also driven back by a certain drive rotational angle; to relieve the tools and other machine parts. In particular, with electric servo drives a correspondingly rapid response to the force measurement or limit value or limit exceeded is readily possible.

Die Messung kann z.B. durch einen Näherungssensor erfolgen oder mit Dehnmessstreifen. Die Kraft kann auch direkt gemessen werden, z.B. mit einer Druckmessdose.The measurement can be done for example by a proximity sensor or with strain gauges. The force can also be measured directly, eg with a pressure cell.

Im folgenden werden Ausführungsformen der Erfindung anhand der Figuren näher erläutert. Dabei zeigt

  • Figur 1 eine teilweise Ansicht einer Clipvorrichtung mit Oberarm, Unterarm und Antriebselementen,
  • Figur 2 eine Ansicht eines Teils des Oberarms mit einer ersten Ausführung der Messeinrichtung,
  • Figur 3 eine Ansicht eines Teils des Oberarms mit einer weiteren, Ausführung der Messeinrichtung; und
  • Figur 4 eine weitere Ansicht eines Teils des Oberarms mit einer weiteren Ausführung der Messeinrichtung.
Embodiments of the invention will be explained in more detail below with reference to the figures. It shows
  • FIG. 1 a partial view of a clip device with upper arm, forearm and drive elements,
  • FIG. 2 a view of a part of the upper arm with a first embodiment of the measuring device,
  • FIG. 3 a view of a portion of the upper arm with a further embodiment of the measuring device; and

Figur 1 zeigt eine teilweise Darstellung einer Clipvorrichtung 1, wobei in dieser Figur im wesentlichen nur der Oberarm und der Unterarm der Vorrichtung und ein Teil der Antriebselemente dargestellt sind. Die Ausbildung einer Clipvorrichtung mit den erwähnten Verdrängerscheren ist dem Fachmann aber bekannt, so dass es dazu keiner weiteren Erläuterungen als der nachfolgend gegebenen bedarf. Die Clipvorrichtung 1 weist ein nur angedeutetes Maschinengestell und Gehäuse 5 auf, welches die Komponenten der Vorrichtung aufnimmt und die entsprechenden Lagerstellen für die angetriebenen Elemente bereitstellt. Insbesondere weist die Clipvorrichtung einen Antrieb 2 auf, der derart ausgestaltet ist, dass er von einer elektronischen Steuerung 4 gesteuert werden kann. Dabei ist der Antrieb 2 insbesondere ein elektrischer Servomotorantrieb und die Steuerung 4 ist z.B. eine industrielle mikroprozessorbasierte Steuerung. Der Antrieb 2 wirkt über nicht näher dargestellte Antriebsmittel 18, wie z.B. Riemen, Ketten, Zahnräder oder weitere Mittel auf Kurvenscheiben 3 ein, welche durch den Antrieb um eine Achse 3' rotierend angetrieben werden. Von den Steuerkurven der Kurvenscheiben werden über Rollen 30 die untere Werkzeughalterung 6 und die obere Werkzeughalterung 7,17 der Clipvorrichtung auf an sich bekannte Weise angetrieben, so dass diese Werkzeughalterungen sich voneinander weg bewegen und aufeinander zu bewegen, um einerseits den Durchtritt der zu verschliessenden befüllten Wursthülle und andererseits die Clipsetzung zu ermöglichen. In dem gezeigten Beispiel ist die obere Werkzeughalterung 7,17, welches Element in der Regel als Oberarm der Clipvorrichtung bezeichnet wird, mit unterbrochenen Linien als 7' und 17' auch in der geöffneten Stellung teilweise angedeutet. Die Bewegungsabläufe von Oberarm und der in der Regel als Unterarm bezeichneten unteren Werkzeughalterung 6 sind dem Fachmann bekannt und müssen hier nicht näher erläutert werden. Bei einer bevorzugten Ausführungsform sind die Clipse Teil eines vorgeformten Clipdrahtes 13, der durch eine Clipzuführung 11 zu den eigentlichen Clipverschliesswerkzeugen 8 und 9 zugeführt wird. Das Werkzeug 8, welches die Matrize sein kann und das Werkzeug 9, welches der Stempel sein kann, sind dabei auf herkömmliche Weise so ausgeführt, dass sie den jeweils vordersten, einen vorgeformten Clip bildenden Bereich des Clipdrahtes 13 beim Schliessen von Unterarm und Oberarm von dem Clipdraht 13 abschneiden und zum geschlossenen Clip fertig formen. Weiter ist es bekannt, dass ein Trennmesser 12 vorgesehen ist, welches die wurstförmige Verpackung zwischen den beiden nacheinander gesetzten Clips, dem Endclip der zuvor gefüllten Wurst und dem Anfangsclip der nachfolgend gefüllten Wurst, zerschneiden kann, so dass einzelne Würste entstehen. Dieses Messer 12 wird natürlich nicht eingesetzt, wenn eine Kette von Würsten erzeugt werden soll. Die Werkzeuge 8 und 9 bzw. Matrize und Stempel, sind an die jeweilige Art der Clips, welche je nach Wurst verschieden ist, angepasst und müssen auch in ihrer Lage zueinander entsprechend eingestellt werden. Matrize und Stempel sind daher auswechselbar und mindestens eines der Werkzeuge, hier der Stempel 9, ist in seiner Lage in bezug auf das andere Werkzeug einstellbar, z.B. indem das Werkzeug an einem Einstellmittel 19 befestigt ist; dies ist bekannt und muss hier nicht näher erläutert werden. Bei nicht korrekter Einstellung dieser sogenannten Clipverschlusshöhe können beim Schliessen von Unterarm und Oberarm zum Verschluss des jeweiligen Clips unzulässig hohe Kräfte auftreten, welche zu einer Beschädigung der Clipvorrichtung führen können. FIG. 1 shows a partial view of a clip device 1, wherein in this figure, substantially only the upper arm and the forearm of the device and a part of the drive elements are shown. However, the formation of a clip device with the mentioned displacement shears is known to the person skilled in the art, so that there is no need for further explanation than the following. The clip device 1 has an only indicated machine frame and housing 5, which receives the components of the device and provides the corresponding bearings for the driven elements. In particular, the clip device has a drive 2, which is designed such that it can be controlled by an electronic controller 4. In this case, the drive 2 is in particular an electric servomotor drive and the controller 4 is, for example, an industrial microprocessor-based control. The drive 2 acts on non-illustrated drive means 18, such as belts, chains, gears or other means on cams 3, which are driven by the drive about an axis 3 'rotating. Of the cams of the cams are about rollers 30, the lower tool holder 6 and the upper tool holder 7,17 of the clip device driven in a known per se, so that these tool holders move away from each other and move towards each other, on the one hand to allow the passage of the closed sausage casing to be closed and on the other hand, the clip setting. In the example shown, the upper tool holder 7,17, which element is usually referred to as the upper arm of the clip device, with broken lines as 7 'and 17' partially indicated even in the open position. The movements of the upper arm and the generally referred to as the lower arm lower tool holder 6 are known in the art and need not be explained in detail here. In a preferred embodiment, the clips are part of a preformed clip wire 13, which is fed by a clip feed 11 to the actual Clipverschliesswerkzeugen 8 and 9. The tool 8, which may be the die and the tool 9, which may be the punch, are designed in a conventional manner so that they each foremost, a preformed clip forming portion of the clip wire 13 when closing the forearm and upper arm of the Cut off clip wire 13 and finish forming the closed clip. Furthermore, it is known that a separating knife 12 is provided, which can cut the sausage-shaped packaging between the two successively set clips, the end clip of the previously filled sausage and the initial clip of the subsequently filled sausage, so that individual sausages arise. This knife 12 is of course not used when a chain of sausages to be produced. The tools 8 and 9 or die and stamp, are adapted to the respective type of clip, which is different depending on the sausage, adapted and must also be adjusted in relation to each other accordingly. Die and punch are therefore interchangeable and at least one of the tools, here the punch 9, is adjustable in its position with respect to the other tool, for example by the tool on a Adjustment means 19 is attached; This is known and need not be explained here. If this so-called clip closure height is not set correctly, inadmissibly high forces can occur when closing the forearm and upper arm to the closure of the respective clip, which can lead to damage to the clip device.

Gemäss der vorliegenden Erfindung wird nun eine Messeinrichtung eingesetzt, welche ein Mass für die Kraft liefert, die beim Schliessen auftritt, und über die Steuerung 4 wird bei Erreichen oder Überschreiten eines Grenzwertes der Kraft auf den Antrieb 2 eingewirkt, um die Vorrichtung zu stoppen. Dadurch kann eine Beschädigung verhindert werden. In dem gezeigten Beispiel ist die Messeinrichtung 10 am vorderen Oberarmteil 17 angeordnet. Die Messeinrichtung könnte auch am Unterarm oder an einem anderen Teil der Werkzeughalterung angeordnet sein oder sie könnte sogar an den Werkzeugen 8 und/oder 9 selber angeordnet sein, so dass sie jeweils beim Austausch des Werkzeuges ebenfalls mitausgetauscht würde. Bevorzugt ist indes die Anordnung an der Werkzeughalterung 6 oder 7,17 und insbesondere am Oberarm 7,17. Von der Messeinrichtung 10 führt ein Kabel 15 oder eine drahtlose Datenverbindung zu der Steuerung 4, was in der Figur 1 lediglich durch ein Stück Kabel 15 an der Messeinrichtung 10 sowie einem Eingangskabel 15 an der Steuerung 4 angedeutet ist. Die Steuerung 4 kann damit die von der Messeinrichtung gemessene Grösse, die proportional der Kraft ist, empfangen womit eine Messung der Kraft vorliegt und die Steuerung kann diese Grösse bzw. die Kraft mit einem vorgegebenen Grenzwert vergleichen.According to the present invention, a measuring device is now used, which provides a measure of the force that occurs when closing, and the controller 4 is acted upon reaching or exceeding a limit value of the force on the drive 2 to stop the device. This can prevent damage. In the example shown, the measuring device 10 is arranged on the front upper arm part 17. The measuring device could also be arranged on the lower arm or on another part of the tool holder or it could even be arranged on the tools 8 and / or 9 itself, so that it would also be exchanged each time the tool was exchanged. However, the arrangement on the tool holder 6 or 7, 17 and in particular on the upper arm 7, 17 is preferred. From the measuring device 10 leads a cable 15 or a wireless data connection to the controller 4, which in the FIG. 1 is indicated only by a piece of cable 15 to the measuring device 10 and an input cable 15 to the controller 4. The controller 4 can thus receive the measured by the measuring device size, which is proportional to the force, which is a measurement of the force and the controller can compare this size or the force with a predetermined limit.

Bei einer Ausführungsform einer Clipvorrichtung kann z.B. die Kraft für den korrekten Verschluss des Clips 10 kN betragen und von der Messeinrichtung wird eine Grösse gemessen, die dieser Kraft entspricht. Es kann dann in diesem Beispiel ein erster Grenzwert von 11 kN vorgegeben werden. Hat nun die Bedienungsperson die Lage der Werkzeuge 8 und 9 zueinander derart falsch eingestellt, dass die beim Schliessen des Clips wirkende Kraft die korrekte Clipkraft übersteigt und den Grenzwert erreicht oder übersteigt, so kann dies durch die Steuerung 4 festgestellt und auf den Antrieb 2 eingewirkt werden, so dass die Clipvorrichtung gestoppt wird. Insbesondere bei einem elektrischen Servomotorantrieb kann die Reaktionszeit des Antriebes so kurz sein, dass die Maschine innerhalb des Clipverschlussvorganges, bei dem die unzulässig hohe Kraft auftritt, noch gestoppt werden kann, andernfalls erfolgt ein Stopp für den oder in dem nächsten Verschliessvorgang. Es wird gemäss der Erfindung so vorgegangen, dass bei dem Erreichen eines ersten Grenzwertes, z.B. dem genannten Grenzwert von 11 kN, die Clipvorrichtung den begonnenen Clipablauf fertig ausführt und den Clip schliesst und dass danach durch die Steuerung 4 und den Antrieb 2 die Clipvorrichtung, z.B. in einer vorgegebenen Nullstellung, z.B. der mit 7' und 17' angedeuteten Offenstellung, gestoppt wird. Auch die Füllmaschine für die Wursthülle wird durch die Steuerung dann gestoppt, was durch ein Synchronisationssignal zwischen Clipvorrichtung und Füllmaschine erfolgt. Weiter wird bevorzugterweise eine Fehlermeldung für die Bedienungsperson auf einer Anzeigeeinrichtung der Clipvorrichtung ausgegeben. Die Bedienungsperson wird darin aufgefordert die Clipverschlusshöhe anzupassen bzw. die Werkzeuge 8 und 9 entsprechend einzustellen. Danach kann die Bedienungsperson die Clipvorrichtung wieder in Betrieb nehmen. Sollte der Grenzwert wieder erreicht werden, so erfolgt erneut der Unterbruch aufgrund des gemessenen Kraftwertes und dessen Auswertung durch die Steuerung.In one embodiment of a clip device, for example, the force for the correct closure of the clip can be 10 kN and the measuring device measures a variable that corresponds to this force. It can then be given in this example, a first limit of 11 kN. Now, if the operator has the position of the tools 8 and 9 set each other so wrong that the force acting on closing the clip force exceeds the correct clip force and reaches or exceeds the limit, this can be determined by the controller 4 and acted on the drive 2 so that the clip device is stopped. Particularly in the case of an electric servomotor drive, the reaction time of the drive can be so short that the machine can still be stopped within the clip closing process, in which the unacceptably high force occurs, otherwise a stop for or in the next closing operation takes place. It is according to the invention proceeded so that when reaching a first limit, for example, the said limit of 11 kN, the clip device completes the clip process started and closes the clip and that thereafter by the controller 4 and the drive 2, the clip device, eg in a predetermined zero position, for example, the 7 'and 17' indicated open position is stopped. The filling machine for the sausage casing is then stopped by the controller, which is done by a synchronization signal between the clip device and filling machine. Furthermore, an error message for the operator is preferably output on a display device of the clip device. The operator is prompted to adjust the clip closure height or adjust the tools 8 and 9 accordingly. Thereafter, the operator can take the clip device back into operation. If the limit value is reached again, the interruption occurs again on the basis of the measured force value and its evaluation by the controller.

Es ist auch ein zweiter, höherer Grenzwert vorgesehen, z.B. 12 kN, bei dessen Erkennung durch die Messeinrichtung 10 und die Steuerung 4 ein sofortiger Stopp der Vorrichtung erfolgt. In diesem Fall wird also der Clipverschlussvorgang nicht zu Ende geführt, sondern der Vorgang sofort unterbrochen. Bevorzugt wird aber danach der Servoantrieb um einen vorgegebenen Winkel rückwärts angetrieben, um die Werkzeuge und die Antriebskomponenten der Vorrichtung zu entlasten. Nach diesem Zurückfahren in die Position 17', 7' bleibt die Vorrichtung stehen und erzeugt wiederum eine Fehlermeldung auf der Anzeigeeinrichtung. Die Bedienungsperson muss dann die Clipverschlusshöhe durch Verstellung des einen oder beider Werkzeuge richtig einstellen, in die Nullstellung fahren, die ja beim Erreichen des zweiten Grenzwertes von der Vorrichtung nicht mehr angefahren wurde, und dann die Vorrichtung erneut starten. Sollte wiederum ein Grenzwert erreicht oder überschritten werden, so erfolgen die geschilderten Vorgänge erneut.It is also a second, higher limit provided, for example 12 kN, in its detection by the measuring device 10 and the controller 4, an immediate stop of the device takes place. In this case, so the clip closure process is not completed, but the process is interrupted immediately. Preferably, however, the servo drive is then driven backwards by a predetermined angle in order to relieve the tools and the drive components of the device. After this return to the position 17 ', 7', the device stops and in turn generates an error message on the display device. The operator must then adjust the clip closure height by adjusting the one or both tools correctly, go to the zero position, which was not approached when reaching the second limit of the device, and then restart the device. If a limit value is again reached or exceeded, the described processes take place again.

Bei der in Figur 1 und Figur 2 gezeigten Ausführungsform ist die Messeinrichtung 10, wie erläutert, am Oberarm 7,17 angeordnet. In dem gezeigten Beispiel ist am vorderen Oberarmteil 17 mindestens ein Dehnmessstreifen 20 angeordnet, insbesondere in einer Vertiefung in der Oberfläche des Teils 17. Der Dehnmessstreifen oder gegebenenfalls die Dehnmessstreifen, falls es sich um mehrere Streifen handelt, können z.B. am Teil 17 angeklebt sein, um eine Verformung desselben aufgrund der beim Verschliessen des Clips auftretenden Kraft zu ermitteln. Bevorzugterweise weist die Messeinrichtung dabei einen Bereich auf, der besonders zur Verformung vorgesehen ist, um die Kraft gut ermitteln zu können. In dem gezeigten Beispiel der Figuren 1 und 2 ist dazu ein Bereich 21 unterhalb der Dehnmesstreifen 20 vorgesehen, welcher durch eine Ausnehmung 23 geschwächt ist, so dass die Clipkraft eine gut messbare Verformung (Stauchung)des Bereichs 21 erzeugt. Diese wird auf bekannte Weise durch den Dehnmessstreifen 20 aufgenommen und über das Übertragungsmittel 15 an die Steuerung abgegeben, durch welche das Signal der Dehnmessstreifen auswertbar ist. Derartige Dehnmessstreifen und die Auswertung von deren Signalen sind dem Fachmann gut bekannt und dies braucht hier nicht näher erläutert zu werden. Die Abgabe des Signals des Dehnmessstreifens direkt an die Steuerung 4 ist natürlich nur als Beispiel zu verstehen, es könnte durchaus eine separate Schaltung vorgesehen sein, welche das analoge Signal des Dehnmessstreifens auswertet und in ausgewerteter Form an die Steuerung 4 abgibt, z.B. direkt als digitales Signal. Diese Schaltung kann auch direkt beim Dehnmessstreifen sitzen, so dass bereits ein aufbereitetes Signal über die Leitung 15 an die Steuerung gelangt.At the in FIG. 1 and FIG. 2 As shown, the measuring device 10, as explained, arranged on the upper arm 7,17. In the example shown, at least one strain gauge 20 is arranged on the front upper arm part 17, in particular in a recess in the surface of the part 17. The strain gauges or optionally the strain gauges, if it is a plurality of strips, may be glued to the part 17, for example a deformation of the same due to the force occurring when closing the clip to determine. Preferably, the measuring device in this case has an area which is provided in particular for deformation in order to be able to determine the force well. In the example shown the FIGS. 1 and 2 For this purpose, a region 21 below the strain gauges 20 is provided, which is weakened by a recess 23, so that the clip force generates a well measurable deformation (compression) of the region 21. This is received in a known manner by the strain gauge 20 and delivered via the transmission means 15 to the controller, through which the signal of the strain gauges can be evaluated. Such strain gauges and the evaluation of their signals are well known in the art and this need not be further explained here. The delivery of the signal of the Dehnmessstreifens directly to the controller 4 is of course only to be understood as an example, it could well be provided a separate circuit which evaluates the analog signal of the strain gauge and outputs in evaluated form to the controller 4, eg directly as a digital signal. This circuit can also sit directly at the strain gauge, so that already passes a processed signal via the line 15 to the controller.

Figur 3 zeigt ein anderes Beispiel einer Messeinrichtung 10, wobei wiederum gleiche Bezugszeichen gleiche Teile bezeichnen. Auch hier weist die Messeinrichtung 10 bevorzugterweise Dehnmessstreifen auf, welche indes in einem eigenen Gehäuse 24 angeordnet sind, dessen Verformung gemessen wird. Dieses Gehäuse kann auch eine Signalaufbereitung enthalten, die z.B. aus der Steuerung 4 gespiesen wird, wie dies bereits erwähnt worden ist. Das Gehäuse 24 ist z.B. an zwei Elementen 25 und 26 des Oberarms 7,17 mittels Gewindebolzen befestigt, so dass sich die Verformung des Oberarms auf das Gehäuse 24 überträgt und somit ebenfalls die Clipkraft gemessen wird. Zwischen den Elementen 25 und 26 ist eine Ausnehmung 27 angeordnet, um die Verformung des Oberarms zu vergrössern. Die zur Clipkraft proportionale Verformung des Gehäuses 24 wird gemessen und wiederum an die Steuerung oder gegebenenfalls eine vorgeschaltete Elektronik abzugeben. Aus diesem Messsignal ermittelt die Steuerung wiederum auf die geschilderte Weise, ob mindestens ein Grenzwert erreicht oder überschritten wird. Die Steuerung kann dann auf die geschilderte Weise auf den Antrieb 2 einwirken. Bei diesem Beispiel kann der Dehnmessstreifen rasch ausgewechselt werden. Nach der Montage erfolgt dann eine Nullsetzung bzw. Eichung bei unbelastetem Dehnmessstreifen. FIG. 3 shows another example of a measuring device 10, again like reference numerals designate like parts. Again, the measuring device 10 preferably strain gauges, which, however, are arranged in a separate housing 24, whose deformation is measured. This housing may also contain a signal conditioning, for example, fed from the controller 4, as has already been mentioned. The housing 24 is fastened, for example, to two elements 25 and 26 of the upper arm 7, 17 by means of threaded bolts, so that the deformation of the upper arm is transmitted to the housing 24 and thus likewise the clip force is measured. Between the elements 25 and 26, a recess 27 is arranged to increase the deformation of the upper arm. The deformation of the housing 24, which is proportional to the clip force, is measured and, in turn, transmitted to the controller or optionally to an upstream electronic system. From this measurement signal, the controller again determines in the manner described whether at least one limit value is reached or exceeded. The controller can then act on the drive 2 in the manner described. In this example, the strain gauge can be replaced quickly. After assembly, then a zeroing or calibration takes place with unloaded strain gauges.

Figur 4 zeigt eine weitere Ausführungsform, wobei hier zur Messung der Clipkraft die Messeinrichtung 10 einen Abstandsensor 31 aufweist, welcher wiederum über ein Kabel 15 mit der Steuerung 4 oder einer vorgeschalteten Elektronik zur Signalaufbereitung verbunden ist. Der Abstandsensor 31 kann ein kapazitiver Abstandsensor sein, welcher geringe Abstandsänderungen einer Zunge 29 der Werkzeughalterung bzw. des Oberarms 17 zu der Stirnfläche des Sensors 31 messen kann. So können zum Beispiel Abstandsänderungen im Bereich von 0,01 mm messbar sein. Entsprechend der wirkenden Clipkraft bewegt sich die Zunge 29 zum Sensor 31 hin und bei Entlastung wieder zurück. Die Zunge ist dabei bevorzugterweise durch eine Ausnehmung 28 im vorderen Oberarmteil 17 selber gebildet, könnte aber auch ein an diesem Oberarm separat befestigtes Teil sein. Durch die Messeinrichtung lässt sich dann wiederum feststellen, ob die Clipkraft einen oder mehrere Grenzwerte erreicht oder übersteigt, so dass die Clipvorrichtung wieder auf die beschriebene Weise durch die Steuerung 4 und den Antrieb 2 gestoppt werden kann. FIG. 4 shows a further embodiment, in which case for measuring the clip force, the measuring device 10 has a distance sensor 31, which in turn via a cable 15 to the controller 4 or an upstream Electronics for signal processing is connected. The distance sensor 31 may be a capacitive distance sensor which can measure small changes in the distance of a tongue 29 of the tool holder or the upper arm 17 to the end face of the sensor 31. For example, distance changes in the range of 0.01 mm may be measurable. In accordance with the acting clip force, the tongue 29 moves towards the sensor 31 and back again upon relief. The tongue is preferably formed by a recess 28 in the front upper arm 17 itself, but could also be a separately attached to this upper arm part. The measuring device can then in turn determine whether the clip force reaches or exceeds one or more limit values, so that the clip device can be stopped again in the manner described by the controller 4 and the drive 2.

Die Messung der Clipkraft kann auch auf andere Weise erfolgen, indem z.B. ein Wert des Antriebes ermittelt wird, der sich ebenfalls proportional zur Clipkraft ändert. Bei einem hydraulischen Maschinenantrieb kann dies der Hydraulikdruck sein, bei dem bereits erwähnten elektrischen Maschinenantrieb kann dies der Motorantriebstrom sein. Es kann aber auch das Drehmoment an einer Welle der Clipvorrichtung gemessen werden, z.B. an der Welle 3' oder das Biegemoment an einer Achse, z.B. an der Unterarm 6 und Oberarm 7, 17 tragenden Achse 33. Auch eine direkte Kraftmessung, z.B. mit einer Druckmessdose beim Werkzeug ist möglich. Die jeweilige Messeinrichtung wird entsprechend ausgestaltet, was für den Fachmann im Rahmen seiner Fachkenntnisse möglich ist. Auch bei diesen Ausführungen wird dann festgestellt, ob die Clipkraft einen oder mehrere vorgegebene Grenzwerte erreicht hat oder überschritten hat und es wird wiederum auf den Maschinenantrieb Einfluss genommen.The measurement of the clip force can also be done in other ways, e.g. a value of the drive is determined, which also changes in proportion to the clip force. In a hydraulic machine drive, this may be the hydraulic pressure, in the case of the electric machine drive already mentioned, this may be the motor drive current. However, it is also possible to measure the torque on a shaft of the clip device, e.g. on the shaft 3 'or the bending moment on an axle, e.g. Also, a direct force measurement, e. g., on the forearm 6 and upper arm 7, 17 bearing axle 33. Also, a direct force measurement, e.g. with a pressure cell at the tool is possible. The respective measuring device is designed accordingly, which is possible for the skilled person within the scope of his specialist knowledge. In these embodiments as well, it is then determined whether the clip force has reached or exceeded one or more predetermined limit values, and in turn the machine drive is influenced.
