Definitions
- the invention relates to a device for producing a crimp connection between a plastically deformable, metallic pole piece which is attached to a cable end and the cable end, comprising an anvil, on which the pole piece can be placed and a stamp which deforms the pole piece in the direction of the anvil is movable, wherein a signal emitting sensor is provided for detecting the maximum deformation of the pole piece and a comparator for comparing the signal with a desired value, which generates a good or bad signal.
- Such a device has the purpose of fixing a pole piece at the end of a cable in such a way that there is an electrically conductive and mechanically permanent connection between the two parts.
- the sensor detects the actually occurring deformation forces and / or paths during each crimping process in the form of a signal, which is transmitted to the comparator and is compared therein with a target value. Larger deviations from the target value are an indicator of defective parts. They are used to control an optical "bad display”. If there are no deviations, then a "good display” is activated. This evaluation is unsatisfactory. In fact, mostly unskilled workers are concerned with the Pohlschuh equipping of cable ends, which mainly work under chord conditions. In the event of distractions or signs of fatigue, bad displays can be overlooked and incorrectly fitted cable ends can be delivered. In terms of security-related applications, that is intolerable, for example with regard to the connection of an airbag to the electronics of a motor vehicle.
- the invention has for its object to develop a device of the type mentioned in such a way that faulty crimped connections between a pole piece and a cable end can no longer occur or are at least clearly recognizable.
- the bad signal of the comparator controls a capping device for the cable end and that the capping device completely or partially disconnects the cable end when actuated.
- the device according to the invention thus uses the devices known per se for detecting faulty crimp connections. These can be due, for example, to the fact that the pole piece as such has a mechanical defect, is incorrectly dimensioned or is not pushed onto the cable end far enough. The result is clear signals that clearly distinguish a faulty connection of this type from a correct connection. They are used to completely or partially cut off a cable end carrying an incorrectly mounted pole piece with the aid of a clipping device, thereby making the incorrect mounting obvious. Cable ends that are incorrectly fitted with pole pieces can thus be easily recognized and rejected without requiring any special inspection effort. Even in the case of delivery, there is no damage insofar as connection to an aggregate is not possible. The user can therefore also recognize the error.
- a device can be integrated into the device, which effects a stripping of the cable end prior to the pinching of the pole shoe.
- it is often difficult to automatically remove separated cable ends.
- the cable end in question is only partially separated from the rest of the cable and connected to it, for example, only by a film hinge, which consists of components of the cable insulation.
- a motor is provided for actuating the cutting device.
- This can be electrically, hydraulically, pneumatically or mechanically driven, for example using a spring accumulator which is loaded by the working cycle of the device. Motors with a high response speed are preferred in the context of the present invention. If necessary, they can also be run through and only engaged to actuate the cutting device.
- the cutting device can contain a pair of scissors through which the cable end is completely or partially severed. In such a case there are no reaction forces in the area of the cable end during the cutting process. This therefore does not need to be particularly noted during the capping process.
- the cutting device contains at least one cutting knife. This can be moved vertically up and down in a guide and can interact, for example, with the anvil and / or an opposing counter knife.
- a design can be made very simple in terms of construction.
- the cutting device can have at least one driver for a severed cable end, for example a clamping device. This can, for example, cooperate with a release device which removes the severed cable end from the device following actuation of the cutting device.
- the device according to the invention ensures that faulty crimped connections between a pole piece and a cable end can no longer occur. Their use is therefore particularly recommended with regard to the pole shoe assembly of cable ends, which are important for safety.
- the manufacture of the device and its integration into existing ones Pick and place machines is relatively simple. There is nothing to prevent a very broad introduction.
- the device shows a device which is intended for producing a crimp connection between a plastically deformable, metallic pole piece 1, which is attached to a cable end 2 and a cable end 2.
- the device comprises an anvil 3, on which the pole piece 2 can be placed, and a stamp 4, which can be moved in the direction of the anvil 3 while deforming the pole piece 1, a sensor 5 emitting a signal 7 being provided for detecting the deformation of the pole piece 1 and a comparator 6 for comparing the signal 7 with a target value 8, which generates a good or bad signal.
- the bad signal is used in the embodiment shown to control a cutting device 9, which is designed like scissors and causes a complete separation of the cable end 2 carrying the incorrectly assembled pole piece 1.
- the further cable end newly obtained after the cable end has been disconnected can then be placed in the device again and fitted again.
- FIG. 1 In principle, the structure shown in FIG. 1 is always present in devices of this type. These generally work semi or fully automatically in such a way that a cable end 2 inserted into the device, similar to the type shown in FIG. 1, reaches a pole shoe 1 which is still open and thereby exceeds a sensor which causes the stamp 4 to move downward.
- the yourself Resulting relative movement of the stamp 4 with respect to its drive 10 is detected by a sensor 5 and supplied as a signal 7 to a comparator 6, in which a setpoint 8 is stored.
- Signals 7, which correspond to the setpoint 8 express that the pole piece 1 in question is properly attached to the cable end 2. If, on the other hand, there is a greater distance between the two values, this means that the corresponding pole piece is incorrectly installed.
- the comparator 6 actuates the cutting device 9, which completely or partially separates the relevant cable end 2, including the pole shoe 1 incorrectly mounted thereon.
- a complete separation with the aid of a cutting device 9 is provided, which functions like scissors.
- the severed cable end is removed from the device, which can be done for example by a mechanical or pneumatic conveyor system.
- the new cable end 2 can then be pushed in and the assembly process can be initiated again with a new pole piece.
- the signal relating to the path of the stamp 4 can optionally be detected by other means or at a different location than shown in FIG. 1, for example by one or more sensors which are provided in or on the machine and / or in or under the anvil are.
- the signal may also refer to the forces that occur when the crimping process is carried out and which may are also suitable for displaying defective parts.
- the scissor-like capping device 9 in contrast to FIG. 1, is mounted in a transversely movable slide 11 and provided with a clamping device for the separated cable end. Detached cable ends can be removed from the device and disposed of in the lateral direction.
- a piston / cylinder arrangement is provided in the embodiment according to FIGS. 1 and 2, to which compressed air can be applied and is connected to the trimming device by a pivotable lever and opposed push rods.
- a compressed air control (not shown) is available for the compressed air supply. This is connected to the comparator 6 in a signal-conducting manner and can be controlled by it.
- the cutting device 9 consists of two knives 9.1 which can be moved towards one another in the vertical direction, which are formed in the central region by knife edges 9.3 facing one another and in the regions adjacent to the knife edges 9.3 by stop surfaces 9.2.
- the knife edges 9.3 When the abutment surfaces 9.2 come into contact with one another, the knife edges 9.3 have a mutual distance of approximately 1/10 mm to 2/10 mm from one another. This is dimensioned just so large that there is no complete separation of a cable to be removed, but such an extensive separation that the relevant cable end can be manually removed from the rest of the cable after removal from the device.
- the mutual distance that the knife edges 9.3 must have in order to achieve this goal with an actuated clipping device is largely determined by the thickness of the cable end equipped with the respective pole piece and by the dimension of a plastic sheathing which possibly surrounds the cable end. Values in the range of 0.1 to 0.3 mm mostly meet this requirement. If necessary, they can be specified by simple tests.
- control of the embodiment according to FIGS. 3 and 4 can be designed similar to that according to FIGS. 1 and 2.

Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung einer Quetschverbindung zwischen einem plastisch verformbaren, metallischen Polschuh, der auf ein Kabelende aufgefügt ist und dem Kabelende, umfassend einen Amboß, auf den der Polschuh auflegbar ist und einen Stempel, der unter Verformung des Polschuhs in Richtung des Ambosses bewegbar ist, wobei ein ein Signal abgebender Sensor zur Erfassung der Maximalverformung des Polschuhs vorgesehen ist sowie ein Komparator zum Vergleichen des Signals mit einem Sollwert, der ein Gut- oder Schlechtsignal erzeugt.The invention relates to a device for producing a crimp connection between a plastically deformable, metallic pole piece which is attached to a cable end and the cable end, comprising an anvil, on which the pole piece can be placed and a stamp which deforms the pole piece in the direction of the anvil is movable, wherein a signal emitting sensor is provided for detecting the maximum deformation of the pole piece and a comparator for comparing the signal with a desired value, which generates a good or bad signal.
Eine solche Vorrichtung ist bekannt. Sie hat den Zweck, einen Polschuh in der Weise am Ende eines Kabels festzulegen, daß sich eine elektrisch leitende und in mechanischer Hinsicht dauerhafte Verbindung zwischen beiden Teilen ergibt. Der Sensor erfaßt zu diesem Zweck bei einem jeden Crimpvorgang die sich tatsächlich ergebenden Verformungskräfte und/oder -wege in Gestalt eines Signals, das dem Komparator übermittelt und in diesem mit einem Sollwert abgeglichen wird. Größere Abweichungen vom Sollwert sind ein Indikator für fehlerhafte Teile. Sie werden zur Ansteuerung einer optischen "Schlechtanzeige" verwendet. Sind keine Abweichungen vorhanden, dann wird hingegen eine "Gutanzeige" aktiviert. Diese Auswertung ist wenig befriedigend. Tatsächlich sind überwiegend ungelernte Arbeitskräfte mit der Pohlschuh-Bestückung von Kabelenden befaßt, die überwiegend unter Akkordbedingungen tätig sind. Bei Ablenkungen oder Ermüdungserscheinungen kann es dazu kommen, daß Schlechtanzeigen übersehen werden und fehlerhaft bestückte Kabelenden zur Auslieferung gelangen. In bezug auf sicherheitsrelevante Anwendungen ist das nicht tolerierbar, beispielsweise in bezug auf den Anschluß eines Airbags an die Elektronik eines Kraftfahrzeuges.Such a device is known. It has the purpose of fixing a pole piece at the end of a cable in such a way that there is an electrically conductive and mechanically permanent connection between the two parts. For this purpose, the sensor detects the actually occurring deformation forces and / or paths during each crimping process in the form of a signal, which is transmitted to the comparator and is compared therein with a target value. Larger deviations from the target value are an indicator of defective parts. They are used to control an optical "bad display". If there are no deviations, then a "good display" is activated. This evaluation is unsatisfactory. In fact, mostly unskilled workers are concerned with the Pohlschuh equipping of cable ends, which mainly work under chord conditions. In the event of distractions or signs of fatigue, bad displays can be overlooked and incorrectly fitted cable ends can be delivered. In terms of security-related applications, that is intolerable, for example with regard to the connection of an airbag to the electronics of a motor vehicle.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art derart weiterzuentwickeln, daß fehlerhafte Quetschverbindungen zwischen einem Polschuh und einem Kabelende nicht mehr vorkommen können oder zumindest klar erkennbar sind.The invention has for its object to develop a device of the type mentioned in such a way that faulty crimped connections between a pole piece and a cable end can no longer occur or are at least clearly recognizable.
Diese Aufgabe wird erfindungsgemäß bei einer Vorrichtung der eingangs genannten Art mit den kennzeichnenden Merkmalen von Anspruch 1 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.This object is achieved according to the invention in a device of the type mentioned at the outset with the characterizing features of
Bei der erfindungsgemäßen Vorrichtung ist es vorgesehen, daß das Schlechtsignal des Komparators die Ansteuerung einer Kappvorrichtung für das Kabelende bewirkt und daß die Kappvorrichtung bei einer Ansteuerung das Kabelende ganz oder teilweise abtrennt. Die erfindungsgemäße Vorrichtung bedient sich somit der an sich bekannten Einrichtungen zur Erfassung fehlerhafter Quetschverbindungen. Diese können beispielsweise darauf zurückzuführen sein, daß der Polschuh als solcher einen mechanischen Defekt aufweist, falsch dimensioniert ist oder nicht weit genug auf das Kabelende aufgeschoben ist. Die Folge sind eindeutige Signale, die eine fehlerhafte Verbindung dieser Art deutlich von einer ordnungsgemäßen Verbindung unterscheiden. Sie werden dazu benutzt, ein einen fehlerhaft montierten Polschuh tragendes Kabelende mit Hilfe einer Kappvorrichtung ganz oder teilweise abzutrennen und die fehlerhafte Montierung dadurch offensichtlich zu machen. Fehlerhaft mit Polschuhen bestückte Kabelenden können dadurch leicht erkannt und ausgesondert werden, ohne daß es eines besonderen Kontrollaufwandes bedarf. Selbst im Falle einer Auslieferung entsteht kein Schaden insofern, als ein Anschluß an ein Aggregat nicht möglich ist. Der Verwender kann den Fehler daher ebenfalls erkennen.In the device according to the invention, it is provided that the bad signal of the comparator controls a capping device for the cable end and that the capping device completely or partially disconnects the cable end when actuated. The device according to the invention thus uses the devices known per se for detecting faulty crimp connections. These can be due, for example, to the fact that the pole piece as such has a mechanical defect, is incorrectly dimensioned or is not pushed onto the cable end far enough. The result is clear signals that clearly distinguish a faulty connection of this type from a correct connection. They are used to completely or partially cut off a cable end carrying an incorrectly mounted pole piece with the aid of a clipping device, thereby making the incorrect mounting obvious. Cable ends that are incorrectly fitted with pole pieces can thus be easily recognized and rejected without requiring any special inspection effort. Even in the case of delivery, there is no damage insofar as connection to an aggregate is not possible. The user can therefore also recognize the error.
Im einfachsten Fall ist es vorgesehen, daß das Kabelende einschließlich des fehlerhaft montierten Polschuhs zur Gänze abgetrennt wird. In solch einem Falle besteht die Möglichkeit, den Fehler zu beheben, indem das Kabelende erneut in die Vorrichtung eingeführt und erneut mit einem neuen Polschuh bestückt wird. Jedes aus der Vorrichtung herausgezogene Kabelende, welches einen Polschuh trägt, ist somit als fehlerfrei betrachtbar.In the simplest case, it is provided that the cable end, including the incorrectly mounted pole piece, is completely separated. In such a case it is possible to remedy the fault by reinserting the cable end into the device and fitting it again with a new pole piece. Each end of the cable that is pulled out of the device and that carries a pole piece can thus be regarded as error-free.
In die Vorrichtung kann eine Einrichtung integriert sein, welche ein dem Anquetschen des Polschuhs vorausgehendes Abisolieren des Kabelendes bewirkt. Aus Platzgründen ist es dabei häufig schwierig, abgetrennte Kabelenden automatisch abzuführen. Tatsächlich besteht ein entsprechendes Erfordernis nur sehr selten, wodurch es genügt, wenn das betreffende Kabelende nur teilweise von dem übrigen Kabel abgetrennt und mit diesem beispielsweise nur noch durch eine Filmscharnier verbunden ist, welches aus Bestandteilen der Kabelisolierung besteht.. Nach der Entnahme aus der Vorrichtung hängt ein solches Kabelende leicht beweglich und abreißbar herunter. Es läßt sich leicht auf manuellem Weg entfernen und der Fehler revidieren, indem das übrige Kabel mit dem neu entstandenen Ende erneut in die Vorrichtung eingeführt wird.A device can be integrated into the device, which effects a stripping of the cable end prior to the pinching of the pole shoe. For reasons of space, it is often difficult to automatically remove separated cable ends. In fact, there is a corresponding requirement very rarely, which is why it is sufficient if the cable end in question is only partially separated from the rest of the cable and connected to it, for example, only by a film hinge, which consists of components of the cable insulation. After removal from the device such a cable end hangs down easily movable and tearable. It can be easily removed manually and the fault can be revised by reinserting the remaining cable with the newly created end into the device.
Für die Betätigung der Kappvorrichtung ist ein Motor vorgesehen. Dieser kann elektrisch, hydraulisch, pneumatisch oder mechanisch angetrieben sein, beispielsweise unter Verwendung eines Federspeichers, der durch den Arbeitstakt der Vorrichtung geladen wird. Motoren mit einer hohen Ansprechgeschwindigkeit werden im Rahmen der vorliegenden Erfindung bevorzugt. Sie können gegebenenfalls auch durchlaufen und nur zur Betätigung der Kappvorrichtung eingekuppelt werden.A motor is provided for actuating the cutting device. This can be electrically, hydraulically, pneumatically or mechanically driven, for example using a spring accumulator which is loaded by the working cycle of the device. Motors with a high response speed are preferred in the context of the present invention. If necessary, they can also be run through and only engaged to actuate the cutting device.
Als besonders vorteilhaft hat es sich bewährt, Druckluftzylinder von verhältnismäßig kleinem Querschnitt zu verwenden. Der sich dabei ergebende, große Arbeitsweg gestattet es, den Bereich, in den das zu bestückende Kabelende einzuführen ist, offen zu gestalten, was die Durchführung von Wartungsarbeiten erleichtert und die Zugänglichkeit der Vorrichtung verbessert. Die Ansteuerung erfolgt zweckmäßig unter Verwendung eines Taktventils, welches zwischen den Druckluftzylinder und einen Druckluftspeicher zwischengeschaltet ist. Der Druckluftkolben des Druckluftzylinders wird dadurch äußerst schnell beschleunigt. Er erreicht zum Zeitpunkt seines Auftreffens auf das Kabel seine maximale Geschwindigkeit und eine große Wucht, was es gestattet, auch dicke Kabelenden problemlos zu durchtrennen und stumpfe Messer weitgehend zu kompensieren. Unter dem Gesichtspunkt der Dauerhaltbarkeit und Wartungsfreundlichkeit ist das von großem Vorteil.It has proven particularly advantageous to use compressed air cylinders of relatively small cross-section. The resultant large working distance allows the area into which the cable end to be fitted is to be designed to be open, which makes it easier to carry out maintenance work and improves the accessibility of the device. The control is expediently carried out using a clock valve, which is interposed between the compressed air cylinder and a compressed air reservoir. Of the The compressed air piston of the compressed air cylinder is accelerated extremely quickly. When it hits the cable, it reaches its maximum speed and great force, which makes it possible to cut through even thick cable ends without problems and largely compensate for blunt knives. This is of great advantage from the point of view of durability and ease of maintenance.
Die Kappvorrichtung kann eine Schere enthalten, durch die das Kabelende ganz oder teilweise abgetrennt wird. In einem solchem Fall ergeben sich während des Kappvorganges keine Reaktionskräfte im Bereich des Kabelendes. Dieses braucht daher während der Durchführung des Kappvorganges nicht besonders festgehalten zu werden.The cutting device can contain a pair of scissors through which the cable end is completely or partially severed. In such a case there are no reaction forces in the area of the cable end during the cutting process. This therefore does not need to be particularly noted during the capping process.
Nach einer anderen Ausgestaltung ist es vorgesehen, daß die Kappvorrichtung zumindest ein Trennmesser enthält. Dieses kann in einer Führung senkrecht auf und ab bewegbar sein und beispielsweise mit dem Amboß und/oder einem gegenläufigen Gegenmesser zusammenwirken. Insbesondere bei Ausführungen, bei denen das Kabelende nur teilweise abzutrennen ist, läßt sich eine solche Ausführung in konstruktiver Hinsicht sehr einfach gestalten.According to another embodiment, it is provided that the cutting device contains at least one cutting knife. This can be moved vertically up and down in a guide and can interact, for example, with the anvil and / or an opposing counter knife. In particular in the case of designs in which the cable end can only be severed partially, such a design can be made very simple in terms of construction.
Die Kappvorrichtung kann zumindest einen Mitnehmer für ein abgetrenntes Kabelende aufweisen, beispielsweise eine Klemmvorrichtung. Diese kann beispielsweise mit einer Abwurfeinrichtung zusammenarbeiten, die das abgetrennte Kabelende im Anschluß an eine Betätigung der Kappvorrichtung aus der Vorrichtung entfernt.The cutting device can have at least one driver for a severed cable end, for example a clamping device. This can, for example, cooperate with a release device which removes the severed cable end from the device following actuation of the cutting device.
Die erfindungsgemäße Vorrichtung stellt sicher, daß fehlerhafte Quetschverbindungen zwischen einem Polschuh und einem Kabelende nicht mehr auftreten können. Ihre Verwendung empfiehlt sich dadurch vor allem in bezug auf die Polschuhbestückung von Kabelenden, die sicherheitsrelevante Bedeutung haben. Die Herstellung der Vorrichtung und ihrer Integration in bereits vorhandenen Bestückungsautomaten ist verhältnismäßig einfach. Einer sehr breitgefächerten Einführung steht daher nichts entgegen.The device according to the invention ensures that faulty crimped connections between a pole piece and a cable end can no longer occur. Their use is therefore particularly recommended with regard to the pole shoe assembly of cable ends, which are important for safety. The manufacture of the device and its integration into existing ones Pick and place machines is relatively simple. There is nothing to prevent a very broad introduction.
Die Erfindung wird nachfolgend anhand der Zeichnung weiter verdeutlicht. Es zeigen:
- Fig. 1 und 2 eine Vorrichtung, bei der die Kappvorrichtung durch eine Schere gebildet ist.
- Fig. 3 und 4 eine Vorrichtung, bei der die Kappvorrichtung durch zwei gegenläufige Trennmesser gebildet ist.
- 1 and 2 a device in which the cutting device is formed by scissors.
- 3 and 4 a device in which the cutting device is formed by two counter-cutting blades.
Fig. 1 zeigt eine Vorrichtung, die zur Herstellung einer Quetschverbindung zwischen einem plastisch verformbaren, metallischen Polschuh 1, der auf ein Kabelende 2 aufgefügt ist und einem Kabelende 2 bestimmt ist. Die Vorrichtung umfaßt einem Amboß 3, auf den der Polschuh 2 auflegbar ist und einen Stempel 4, der unter Verformung des Polschuhs 1 in Richtung des Ambosses 3 bewegbar ist, wobei ein ein Signal 7 abgebender Sensor 5 zur Erfassung der Verformung des Polschuhs 1 vorgesehen ist sowie ein Komparator 6 zum Vergleichen des Signals 7 mit einem Sollwert 8, der ein Gut- oder Schlechtsignal erzeugt. Das Schlechtsignal wird bei der gezeigten Ausführung zur Ansteuerung einer Kappvorrichtung 9 verwendet, die scherenartig gestaltet ist und eine völlige Abtrennung des den fehlerhaft montierten Polschuh 1 tragenden Kabelendes 2 bewirkt. Das nach der Abtrennung des Kabelendes neu erhaltene weitere Kabelende kann anschließend erneut in die Vorrichtung gegeben und aufs neue bestückt werden.1 shows a device which is intended for producing a crimp connection between a plastically deformable,
Der in Fig. 1 gezeigte Aufbau ist prinzipiell bei Vorrichtungen dieser Art stets vorhanden. Diese arbeiten im allgemeinen halb- oder vollautomatisch dergestalt, daß ein in die Vorrichtung eingeschobenes Kabelende 2 ähnlich der in Fig. 1 gezeigten Art in einen noch offenen Polschuh 1 gelangt und dabei einen Sensor überschreitet, der eine Abwärtsbewegung des Stempels 4 bewirkt. Die sich dabei ergebende Relativbewegung des Stempels 4 in bezug auf seinen Antrieb 10 wird mittels eines Sensors 5 erfaßt und als Signal 7 einem Komparator 6 zugeführt, in dem ein Sollwert 8 abgespeichert ist. Signale 7, die dem Sollwert 8 entsprechen, drücken aus, daß der betreffende Polschuh 1 in ordnungsgemäßer Weise an dem Kabelende 2 befestigt ist. Ist zwischen beiden Werten hingegen ein größerer Abstand vorhanden, so bedeutet das, daß der entsprechende Polschuh fehlerhaft montiert ist. Durch den Komparator 6 wird an einem solchen Fall die Kappvorrichtung 9 betätigt, die das betreffende Kabelende 2 einschließlich des daran fehlerhaft montierten Polschuhs 1 ganz oder teilweise abtrennt. Bei der Ausführung nach Fig. 1 ist eine völlige Abtrennung mit Hilfe einer Kappvorrichtung 9 vorgesehen, die scherenartig funktioniert. Das abgetrennte Kabelende wird aus der Vorrichtung entfernt, was beispielsweise durch eine mechanische oder pneumatische Förderanlage erfolgen kann. Das neue Kabelende 2 kann anschließend nachgeschoben und der Bestückungsvorgang mit einem neuen Polschuh aufs neue eingeleitet werden.In principle, the structure shown in FIG. 1 is always present in devices of this type. These generally work semi or fully automatically in such a way that a
Das auf den Weg des Stempels 4 bezogene Signal kann gegebenenfalls durch andere Mittel oder an anderer Stelle erfaßt sein, als in Fig. 1 gezeigt, beispielsweise durch einen oder mehrere Sensoren, die in oder an das Maschinengestellt und/oder in oder unter dem Amboß vorgesehen sind. Darüber hinaus kann sich das Signal gegebenenfalls auch auf die Kräfte beziehen, die bei der Durchführung des Crimpvorgangs entstehen und die u.U. ebenfalls geeignet sind, fehlerhafte Teile anzuzeigen.The signal relating to the path of the
Bei der Ausführung nach Fig. 2 ist die scherenartig gestaltete Kappvorrichtung 9 abweichend von Fig.1 in einem querbeweglichen Schieber 11 gelagert und mit einer Klemmeinrichtung für das abgetrennte Kabelende versehen. Abgetrennte Kabelenden lassen sich hierdurch in seitlicher Richtung aus der Vorrichtung entfernen und entsorgen.In the embodiment according to FIG. 2, the scissor-
Für den Antrieb der Kappvorrichtung 9 ist bei der Ausführung nach den Fig. 1 und 2 eine Kolben-/Zylinderanordnung vorgesehen, die mit Druckluft beaufschlagbar und mit der Kappvorrichtung durch einen schwenkbaren Hebel und gegenläufige Schubstangen verbunden ist. Für die Druckluftversorgung ist eine nicht gezeigte Druckluftsteuerung vorhanden. Diese ist signalleitend mit dem Komparator 6 verbunden und durch diesen ansteuerbar.
Bei der in den Fig. 3 und 4 gezeigten Vorrichtung besteht die Kappvorrichtung 9 aus zwei in senkrechter Richtung aufeinander zu bewegbaren Messern 9.1, die im mittleren Bereich durch einander zugewandte Messerschneiden 9.3 gebildet sind und in den den Messerschneiden 9.3 seitlich benachbarten Bereichen durch Anschlagflächen 9.2. Bei einer gegenseitigen Anlageberührung der Anschlagflächen 9.2 haben die Messerschneiden 9.3 einen gegenseitigen Abstand von ca. 1/10 mm bis 2/10 mm voneinander. Dieser ist gerade so groß bemessen, daß sich keine völlige Abtrennung eines zu entfernenden Kabels ergibt, jedoch eine so weitgehende Abtrennung, daß sich das betreffende Kabelende nach dem Entnehmen aus der Vorrichtung manuell von dem restlichen Kabel entfernen läßt. Der gegenseitige Abstand, den die Messerschneiden 9.3 zum Erreichen dieses Zieles bei einer betätigten Kappvorrichtung haben müssen, wird maßgeblich durch die Dicke des mit dem jeweiligen Polschuh bestückten Kabelendes bestimmt sowie durch die Dimension einer das Kabelende gegebenenfalls umschließenden Ummantelung aus Kunststoff. Werte im Bereich von 0,1 bis 0,3 mm werden dieser Forderung zumeist gerecht. Sie lassen sich im Bedarfsfalle durch einfache Versuche präzisieren.For the drive of the
In the device shown in FIGS. 3 and 4, the
Die Ansteuerung der Ausführung nach den Fig. 3 und 4 kann ähnlich derjenigen nach den Fig. 1 und 2 gestaltet sein.The control of the embodiment according to FIGS. 3 and 4 can be designed similar to that according to FIGS. 1 and 2.
