Description

Die Erfindung betrifft eine Vorrichtung zum Handhaben oder Herstellen von Packungen aus Verpackungsmaterial, wie Papier, Karton, Folie etc., mit einem bewegbaren Handhabungsaggregat, insbesondere mit einem drehend angetriebenen (Falt-)Revolver und mit bewegbaren Organen am Handhabungsgerät, wie Faltorganen, Andrückorganen, Stößeln, Schiebern etc. Eine solche Vorrichtung ist zum Beispiel aus DE-A-196 54 394 bekannt.The invention relates to a device for handling or manufacturing of packaging made of packaging material, such as paper, cardboard, Foil etc., with a movable handling unit, in particular with a rotating (folding) turret and with movable organs on the handling device, such as folding organs, Pressure elements, plungers, slides etc. Such a device is known for example from DE-A-196 54 394.

Die Leistungsfähigkeit von Verpackungsmaschinen, insbesondere von sehr komplexen, schnellaufenden Zigaretten-Verpackungsmaschinen, ist erheblich beeinflußt von fehlerbedingten Stillstandszeiten. Es ist deshalb wichtig, etwaige Fehlfunktionen vor allem im Bereich der komplexen Faltrevolver kurzfristig festzustellen und danach unverzüglich die Verpackungsmaschine abzustellen, um Folgeschäden eines Fehlers zu vermeiden. The performance of packaging machines, in particular of very complex, high-speed cigarette packaging machines, is significantly influenced by downtimes caused by errors. It is therefore important to avoid any malfunctions especially in the area of complex folding revolvers at short notice and then immediately determine the packaging machine to prevent consequential damage from an error.

Es ist deshalb Thema der Erfindung, bewegbare Organe eines Faltrevolvers oder anderen Aggregats, insbesondere Falthebel, hin- und herbewegbare Stößel etc. hinsichtlich etwaiger Fehlstellungen zu überwachen, also hinsichtlich Abweichungen von der korrekten Stellung innerhalb eines Bewegungszyklus'. Etwa festgestellte Fehlpositionen erzeugen ein Fehlersignal, welches je nach gegebenen Umständen ein Abschalten der Verpackungsmaschine bewirkt.It is therefore the subject of the invention, movable organs one Folding turret or other unit, in particular folding lever, reciprocating plungers etc. with regard to possible misalignments to monitor, ie with regard to deviations from the correct position within a movement cycle. Approximately Detected incorrect positions generate an error signal, which Depending on the circumstances, the packaging machine may be switched off causes.

Die der Erfindung zugrundeliegende Aufgabe besteht darin, eine zuverlässige, auch bei ungünstigem Umfeld dauerhaft wirksame Überwachung der beweglichen Organe einer Verpackungsmaschine vorzuschlagen, die bei Fehlstellungen der überwachten Organe ein Fehlersignal auslöst.The object underlying the invention is a reliable, permanently effective even in an unfavorable environment Monitoring the moving parts of a packaging machine to propose the malposition of the monitored organs triggers an error signal.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Vorrichtung gekennzeichnet durch mechanische Tastorgane, die bei einer Fehlfunktion oder Fehlstellung des bewegbaren Organs durch die fortgesetzte Bewegung des Handhabungsaggregats beaufschlagbar sind und dadurch infolge Relativbewegung ein Fehlersignal erzeugen können.The device according to the invention is used to achieve this object characterized by mechanical probes that malfunction or malposition of the movable organ through the continued movement of the handling unit can be acted upon are an error signal due to relative movement can generate.

Die Überwachungseinrichtung für bewegbare Organe arbeitet mechanisch. Es werden sonst allgemein zur Überwachung eingesetzte optoelektronische Organe, insbesondere Lichtschranken, wegen der von diesen ausgehenden Fehler vermieden. Die erfindungsgemäße (mechanische) Überwachungseinrichtung ist besonders geeignet bei Verpackungsmaschinen, bei denen die überwachten Organe ganz oder teilweise in abgekapselten Bereichen untergebracht sind und ständig mit Öl versorgt werden bzw. in einem Ölbad laufen.The monitoring device for movable organs works mechanically. Otherwise they are generally used for monitoring optoelectronic organs, especially light barriers, because of the errors emanating from these avoided. The invention (Mechanical) monitoring device is particularly suitable in packaging machines where the monitored organs entirely or partially housed in enclosed areas and are constantly supplied with oil or in an oil bath to run.

Gemäß einem weiteren Vorschlag der Erfindung kann ein mechanisches Stell- bzw. Betätigungsgetriebe zur Erkennung von Fehlstellungen innerhalb des abgekapselten Raums angeordnet sein, während sich fehlerauslösende Organe, zum Beispiel berührungslose elektrische Schaltorgane (Initiatoren) außerhalb dieses Bereichs befinden.According to a further proposal of the invention, a mechanical Actuator or actuating gear to detect malpositions be located inside the enclosed space, while organs that trigger errors, for example non-contact electrical switching devices (initiators) outside of this Area.

Ein anderes Thema der Erfindung ist die Ausgestaltung von Stößeln eines Faltrevolvers, derart, daß bei Überbelastung eines derartigen Stößels infolge eines Fehlers der Stößel von einem Antrieb abkuppelbar ist. Diese Abkopplung führt zur Vermeidung von zerstörenden Bewegungen des Stößels, aber auch zu einer Fehlstellung desselben, die erfindungsgemäß erkannt wird.Another subject of the invention is the design of Tappet of a folding turret, such that when overloaded of such a tappet due to a failure of the tappet of a drive can be uncoupled. This decoupling leads to avoidance of destructive movements of the ram, but also too a malposition thereof which is recognized according to the invention.

Der Faltrevolver 10 ist längs des Umfangs mit Faltdornen 11 versehen. Es handelt sich dabei um langgestreckte, dünnwandige Hohlkörper zur Aufnahme einer Zigarettengruppe. Auf der Außenseite des Faltdorns 11 werden während der Drehbewegung des Faltrevolvers 10 nacheinander Zuschnitte aus Verpackungsmaterial gefaltet, nämlich insbesondere eine Innenumhüllung aus Stanniol oder Papier und eine becherförmige Außenumhüllung aus Papier.The folding turret 10 is provided with folding mandrels 11 along the circumference Mistake. It is elongated, thin-walled Hollow body for holding a group of cigarettes. On the outside of the folding mandrel 11 are during the rotational movement of the Folding turret 10 cuts from packaging material in succession folded, namely in particular an inner wrapping Tinfoil or paper and a cup-shaped outer wrapping Paper.

Nach Durchführung der erforderlichen Faltungen wird die aus der Zigarettengruppe und den teilweise bzw. vollständig gefalteten Zuschnitten bestehende Einheit aus dem Faltdorn 11 aus- bzw. von diesem abgeschoben. Hierzu dienen langgestreckte Stößel 12, die längs des Umfangs des Faltrevolvers 10 in achsparalleler Richtung gelagert und jedem Faltdorn 11 zugeordnet sind. Zum Ausschieben einer Zigarettengruppe aus einem Faltdorn 11 unter Mitnahme der gefalteten Zuschnitte tritt der Stößel 12 mit einem Stößelkopf 13 über eine offene Seite in den Faltdorn 11 ein und schiebt die Zigarettengruppe unter Mitnahme der außen am Faltdorn 11 anliegenden Zuschnitte aus. Die Einheit aus Zigarettengruppe und Zuschnitten wird an eine benachbart positionierte Falttasche 14 des Faltrevolvers 10 übergeben und in deren Bereich fertiggefaltet. Der Stößel 12 kehrt danach aus der Ausschubstellung (Fig. 1 unten) in die Ausgangsstellung (Fig. 1 oben) zurück.After performing the necessary folds, the Cigarette group and the partially or fully folded Cut existing unit out of folding mandrel 11 or deported from this. Elongated plungers 12 serve this purpose, the along the circumference of the folding turret 10 in parallel to the axis Direction stored and each folding mandrel 11 are assigned.

The control groove 16 is designed so that by the running in this tracer roller 15 back and forth Motion is transmitted to the plunger 12.

Bei dem vorliegenden Ausführungsbeispiel ist die Tastrolle 15 seitlich an einem Schlitten 18 angebracht, der seinerseits mit dem Stößel 12 verbunden ist. Der Schlitten 18 wird demnach mit dem Stößel 12 hin- und herbewegt. Zu diesem Zweck ist der Schlitten 18 geführt, und zwar auf zwei im Abstand voneinander angeordneten, parallelen Führungsstangen 19, 20. Der Stößel 12 verläuft mittig zwischen den beiden Führungsstangen 19, 20.In the present exemplary embodiment, the feeler roller is 15 laterally attached to a carriage 18, which in turn with the plunger 12 is connected.

The permanent magnets 23 are in recesses 25 of the carriage 18 positioned such that the Permanent magnets 23, 24 on the (metallic) cross piece 21 facing The page lies approximately flush with the back of the Carriage 18. By the magnetic force of the permanent magnets 23, 24 becomes the connection between the carriage 18 and the crosspiece 21 consequently produced with the plunger 12.

Der Schlitten 18 ist zur Aufnahme der Dauermagnete 23, 24 bzw. zur Bildung der Ausnehmungen 25 an der Unterseite bzw. Innenseite mit einem etwa rechteckigen, mittig angeordneten Ansatz 26 versehen. Dieser dient auch zur Gewährleistung einer exakten Relativstellung des Stößels 12 zum (geführten) Schlitten 18. Das Querstück 21 ist nämlich an beiden Seiten mit winkelförmigen Paßstücken 27, 28 versehen. Diese treten formschlüssig in durch die Kontur des Schlittens 18 und des Ansatzes 26 gebildete winkelförmige Ausnehmungen ein und gewährleisten so eine drehsichere Führung des Stößels 12.The carriage 18 is for receiving the permanent magnets 23, 24 or to form the recesses 25 on the underside or inside with an approximately rectangular, centrally arranged approach 26 provided. This also serves to ensure an exact Relative position of the plunger 12 to the (guided) slide 18. The crosspiece 21 is namely on both sides with angular Fitting pieces 27, 28 provided.

Die lösbare Verbindung des Stößels 12 mit dessen Antrieb, also der Tastrolle 15, soll Folgen einer Störung vermeiden, insbesondere Bruch durch Überbelastung des Stößels 12. Wenn beispielsweise im Bereich des Faltdorns 11 ein Materialstau auftritt, soll verhindert werden, daß der Stößel 12 bzw. der Stößelkopf 13 durch den Zwangsantrieb der Tastrolle 15 unter Zerstörung von empfindlichen Organen in Axialrichtung weiterbewegt wird. Wenn eine bestimmte Schubkraft der Tastrolle 15 überschritten ist, wird die Verbindungskraft der Dauermagnete 23, 24 überwunden. Der Schlitten 18 löst sich vom Stößel 12 bzw. vom Querstück 21 und wird ohne Übertragung einer Vorschubkraft gleitend auf dem Stößel 12 verschoben, entsprechend der Bewegung der Tastrolle 15.The releasable connection of the plunger 12 with its drive, that is the feeler roller 15, should avoid consequences of a malfunction, in particular Breakage caused by overloading the ram 12. If, for example A material jam occurs in the area of the folding mandrel 11, should be prevented that the plunger 12 or Ram head 13 by the positive drive of the feeler roller 15 under Destruction of sensitive organs continues in the axial direction becomes. If a certain thrust of the feeler roller 15 is exceeded, the connecting force of the permanent magnets 23, 24 overcome. The carriage 18 detaches from the plunger 12 or from the cross piece 21 and is without transmission of a feed force slidably moved on the plunger 12, according to the Movement of the feeler roller 15.

Ein etwaiger Fehler im vorstehend beschriebenen Sinne, aber auch andere Fehler, die sich in einer Fehlstellung eines bewegbaren Organs auswirken, wird ständig überwacht und führt infolge Drehung des Faltrevolvers 10 zu einer Fehleranzeige und als Konsequenz zu einem Abschalten der Verpackungsmaschine. Zu diesem Zweck wird die Stellung der bewegbaren Organe - im vorliegenden Falle der Stößel 12 - durch ausschließlich bzw. überwiegend mechanische Organe durchgeführt. Dadurch kann die Überwachungs- bzw. Kontrolleinrichtung in einem schwer zugänglichen Bereich der Verpackungsmaschine bzw. vor allem in einem mit Öl versorgten, abgekapselten Bereich wirken.A possible error in the sense described above, however other errors that result in a malposition of a movable Impact organ is constantly monitored and leads as a result Rotation of the folding turret 10 to an error display and as a consequence of switching off the packaging machine. To For this purpose, the position of the movable organs - in the present Case of the plunger 12 - by exclusively or predominantly mechanical organs performed. This enables the monitoring or control device in a difficult to access Area of the packaging machine or especially in one with oil supplied, encapsulated area.

Bei einer Fehlstellung des bewegbaren Organs, nämlich des Stößels 12, werden Tastorgane beaufschlagt, die in der Bewegungsbahn des Stößels 12 positioniert sind. Es handelt sich dabei um dünnwandige, aus Flachmaterial bestehende Tastfahnen 29, 30, 31. Diese sind längs des Umfangs des Faltrevolvers 10 ortsfest positioniert. Bei dem vorliegenden Ausführungsbeispiel (Fig. 4) ist eine Überwachungseinheit 32 aus drei in Bewegungsrichtung aufeinanderfolgenden Tastfahnen 29, 30, 31 am Außenumfang des Faltrevolvers 10 positioniert. Eine Beaufschlagung dieser Tastorgane bzw. Tastfahnen 29, 30, 31 bewirkt ein Fehlersignal aufgrund einer Bewegung, nämlich Schwenkbewegung der Tastfahnen 29, 30, 31.In the event of a malposition of the movable organ, namely the Ram 12, feelers are acted upon in the path of motion of the plunger 12 are positioned. These are around thin-walled sensing tabs 29 made of flat material, 30, 31. These are fixed along the circumference of the folding turret 10 positioned. In the present embodiment (Fig. 4) is a monitoring unit 32 of three in the direction of movement successive tactile flags 29, 30, 31 on the outer circumference of the folding turret 10 positioned. An application these sensing elements or sensing lugs 29, 30, 31 cause an error signal due to a movement, namely swiveling movement of the Touch flags 29, 30, 31.

Die Tastfahnen 29, 30, 31 sind so positioniert, daß bei jeder denkbaren Fehlstellung des Stößels 12 eine der Tastfahnen 29, 30, 31 beaufschlagt wird. Überwacht wird das vom Stößelkopf 13 abliegende Ende des Stößels 12, und zwar das Querstück 21. Dieses ist mit einem Vorsprung bzw. einer radial nach außen gerichteten Nase 33 versehen, die eine der Tastfahnen 29, 30, 31 bei einer Fehlstellung beaufschlagt. Die Nase 33 als Teil des Stößels 12 bewegt sich bei korrektem Bewegungszyklus des Stößels 12 außerhalb der Stellung der Tastfahnen 29, 30, 31. In Fig. 6 ist die Bewegungsbahn 34 der Nase 33 als strichpunktierte Linie gezeigt. Kommt es zu einer Fehlstellung, befindet sich die Bewegungsbahn der Nase 33 (infolge Drehung des Faltrevolvers 10) versetzt zur Bewegungsbahn 34, bezogen auf Fig. 6 links von dieser. Dadurch wird - je nach Stellung des Stößels 12 bei Auftreten des Fehlers - eine der Tastfahnen 29, 30, 31 mit Sicherheit durch die Nase 33 beaufschlagt und zum Auslösen eines Signals verstellt. Die Tastfahnen 29, 30, 31 sind zu diesem Zweck mit unterschiedlichen Breiten ausgebildet, um alle in Betracht kommenden Relativstellungen der Nase 33 zu berücksichtigen. Die in Drehrichtung des Faltrevolvers 10 erste Tastfahne 29 ist als verhältnismäßig schmaler Materialstreifen ausgebildet, um die mögliche Position der Nase 33 im Bereich der Ausgangsstellung des Stößels 12 abzudecken. In Drehrichtung folgt die Tastfahne 30, die in dem dem Faltrevolver 10 bzw. der Bewegungsbahn der Nase 33 zugekehrten Bereich mit einer streifenförmigen Verbreiterung 35 versehen ist. Die dritte Tastfahne 31 erstreckt sich über die volle Bewegungsamplitude der Nase 33 in Axialrichtung gesehen. Die Tastfahne 31 besteht ebenfalls aus einem schmalen Materialstreifen mit einer quergerichteten Verbreiterung 36.The tactile flags 29, 30, 31 are positioned so that each conceivable misalignment of the plunger 12 one of the sensing lugs 29, 30, 31 is applied. This is monitored by the plunger head 13 distal end of the plunger 12, namely the cross piece 21. This is with a projection or a radially outward Provide nose 33, one of the tactile flags 29, 30, 31 acted upon in the event of a malposition. The nose 33 as part of the Ram 12 moves when the movement cycle is correct Ram 12 outside the position of the feelers 29, 30, 31. In Fig. 6 is the path of movement 34 of the nose 33 as a dash-dotted line Line shown. If there is a misalignment the path of movement of the nose 33 (due to rotation of the folding turret 10) offset from the movement path 34, based on FIG. 6 left of this. This will - depending on the position of the plunger 12 when the error occurs - one of the sensing flags 29, 30, 31 surely acted upon by the nose 33 and to trigger of a signal. The tactile flags 29, 30, 31 are for this Purpose with different widths to fit all in Consider relative positions of the nose 33. The first probe flag in the direction of rotation of the folding turret 10 29 is designed as a relatively narrow strip of material, around the possible position of the nose 33 in the area of the starting position to cover the plunger 12. In the direction of rotation follows the tactile flag 30, which in the folding turret 10 or the movement path the area facing the nose 33 with a strip-shaped Widening 35 is provided. The third tactile flag 31 extends over the full amplitude of movement of the nose 33 in Axial direction seen. The tactile flag 31 also consists of a narrow strip of material with a transverse widening 36th

Alle Tastorgane bzw. Tastfahnen 29, 30, 31 sind im unteren Bereich des Faltrevolvers 10 positioniert. Die Tastfahne 29 ist wegen seitlich versetzter Anordnung mit einer Abwinklung 37 versehen, an derem Ende ein abgewinkelter Schenkel 38 zur Beaufschlagung durch die Nase 33 angeordnet ist.All sensing elements or sensing lugs 29, 30, 31 are in the lower area of the folding turret 10 positioned. The tactile flag 29 is because of a laterally offset arrangement with a bend 37 provided, at the end of an angled leg 38 for loading is arranged through the nose 33.

Die bei Fehlstellungen ausgelösten Bewegungen der einen oder anderen Tastfahne 29, 30, 31 werden über ein mechanisches Gestänge auf Schaltorgane übertragen. Bei dem gezeigten Beispiel ist jede Tastfahne 29, 30, 31 mit einer drehbaren Schaltwelle 39, 40, 41 verbunden. Diese mit den Enden drehbar gelagerten Schaltwellen 39, 40, 41 sind in einem Gehäuse 42 gelagert, welches zum Faltrevolver 10 bzw. zum Gehäuse desselben hin offen ist. Die Schaltwellen 39, 40, 41 treten mit einem Betätigungsende 43 über eine Wandung des Gehäuses 42 aus diesem aus. Die durch die Schaltwellen 39, 40, 41 betätigten Schaltorgane liegen außerhalb des Gehäuses 42.The movements of one or the other caused by malpositions other flag 29, 30, 31 are on a mechanical linkage transferred to switching elements. In the example shown is each flag 29, 30, 31 with a rotatable switching shaft 39, 40, 41 connected. These are pivoted with the ends Switching shafts 39, 40, 41 are mounted in a housing 42, which open to the turret 10 or the housing thereof is. The switching shafts 39, 40, 41 occur with an actuation end 43 from a wall of the housing 42 from this. The are actuated by the switching shafts 39, 40, 41 switching elements outside the housing 42.

Bei dem gezeigten Ausführungsbeispiel sind berührungslose Schalter, nämlich sogenannte Initiatoren 44, 45, 46 als Schaltorgane vorgesehen. Diese Initiatoren 44, 45, 46 werden durch Schalthebel 47 betätigt bzw. beaufschlagt, die berührungslos an einem Ende des Initiators 44, 45, 46 vorbeibewegt werden. In der Ausgangsstellung befinden sich die Schalthebel 47 in einer Position unmittelbar benachbart zu dem zugeordneten Initiator 44, 45, 46 (Stellung mit ausgezogenen Linien in Fig. 5). Bei Betätigung eines Initiators 44, 45, 46 aufgrund eines festgestellten Fehlers wird der Schalthebel 47 in die eine oder andere Stellung außerhalb der unmittelbaren Nachbarschaft zum Initiator 44, 45, 46 bewegt (strichpunktiert in Fig. 5). Dadurch wird in dem Initiator 44, 45, 46 ein Signal ausgelöst, welches beispielsweise einem zentralen Rechner zur Auswertung zugeleitet wird.In the embodiment shown are non-contact Switches, namely so-called initiators 44, 45, 46 as switching elements intended. These initiators 44, 45, 46 are through Switch lever 47 is actuated or acted upon, the contactless be moved past one end of the initiator 44, 45, 46. In the starting position, the shift lever 47 are in one Position immediately adjacent to the assigned initiator 44, 45, 46 (position with solid lines in Fig. 5). at Actuation of an initiator 44, 45, 46 based on a detected Error, the shift lever 47 in one way or another Position outside the immediate vicinity of the initiator 44, 45, 46 moves (dash-dotted in Fig. 5). Thereby a signal is triggered in the initiator 44, 45, 46, which for example fed to a central computer for evaluation becomes.

Die Schalthebel sind unmittelbar an einem Ende, nämlich am Betätigungsende 43, der Schaltwellen 39, 40, 41 angeordnet als einseitig abstehende Arme. Eine Drehbewegung der einen oder anderen Schaltwelle 39, 40, 41 infolge Beaufschlagung einer Tastfahne 29, 30, 31 bewirkt demnach eine Schwenkbewegung des zugeordneten Schalthebels 47 in der einen oder anderen Richtung und damit die Auslösung eines Fehlers.The shift levers are directly at one end, namely at the actuation end 43, the switching shafts 39, 40, 41 arranged as arms protruding on one side. A rotation of one or the other Switching shaft 39, 40, 41 due to the application of a Touch flag 29, 30, 31 accordingly causes a pivoting movement of the assigned shift lever 47 in one direction or the other and thus triggering an error.

Das beschriebene Stell- bzw. Betätigungsgetriebe ist mit einer Rückstelleinrichtung in die Normal- bzw. Ausgangsstellung versehen. Zu diesem Zweck sind an den Enden der Schaltwellen 39, 40, 41 bzw. am Betätigungsende 43 jeweils quergerichtete Schwenkhebel 48 angeordnet. An deren Enden wiederum befinden sich vorgespannte Federn, nämlich Zugfedern 49, 50, deren anderes Ende fest verankert ist. Die Zugfedern 49, 50 ziehen den Schwenkhebel 48 und damit die Schaltwelle 39, 40, 41 in die Normalstellung (quergerichtete Stellung des Schwenkhebels 48). Eine Betätigung des Schalthebels 47 erfolgt demnach gegen die Belastung der Zugfedern 49 oder 50.The described actuating gear is with a Provide reset device in the normal or initial position. For this purpose, at the ends of the switching shafts 39, 40, 41 or at the actuating end 43 each transverse Swivel lever 48 arranged. At the ends are again biased springs, namely tension springs 49, 50, the other End is firmly anchored. The tension springs 49, 50 pull the Swivel lever 48 and thus the shift shaft 39, 40, 41 in the Normal position (transverse position of the pivot lever 48). Actuation of the shift lever 47 accordingly takes place against the Tension springs 49 or 50 loaded.

Die Tastfahnen 29, 30, 31 werden bei einer Fehlstellung des Stößels 12 und damit der Nase 33 durch diese beaufschlagt. Aufgrund der Relativstellung wird die Nase 33 in einem derartigen Falle gegen eine der Tastfahnen 29, 30, 31 bewegt (Fig. 5), so daß diese eine Schwenkbewegung ausführt. Diese wird in der beschriebenen Weise auf das Schaltorgan, nämlich einen der Initiatoren 44, 45, 46, übertragen.The tactile flags 29, 30, 31 are in the event of an incorrect position of the Ram 12 and thus the nose 33 acted upon by this. by virtue of the relative position is the nose 33 in such a Trap against one of the feeler flags 29, 30, 31 moved (Fig. 5), so that this performs a pivoting movement. This is described in the Way on the switching element, namely one of the initiators 44, 45, 46.

Die Überwachungseinheit 32 ist überwiegend in einem abgekapselten Bereich untergebracht, so daß die Überwachung der Stößel 12 oder anderer Organe beispielsweise auch in einem mit Öl versorgten Bereich wirken kann. Die Übertragungsmechanik führt im Bereich drehbarer Organe aus dem abgekapselten Bereich, nämlich aus dem Gehäuse 42 heraus, so daß geeignete, auch empfindliche Schaltorgane außerhalb dieses abgekapselten Bereichs liegen.The monitoring unit 32 is predominantly encapsulated Area housed so that the monitoring of the plunger 12th or other organs, for example, even in an oil-supplied one Area can act. The transmission mechanics leads in Area of rotatable organs from the encapsulated area, namely out of the housing 42, so that suitable, even sensitive Switching elements are outside this encapsulated area.

Die beschriebene Überwachung kann auch für andere Organe eingesetzt werden, beispielsweise für schwenkbar bewegte Faltorgane oder andere Organe. Des weiteren kann die druckbegrenzte Betätigung der Stößel 12 auch auf andere Weise ausgebildet sein, nämlich mit mechanischen Rastorganen anstelle der Dauermagnete 23, 24.The monitoring described can also be used for other organs are used, for example, for pivotably moving folding members or other organs. Furthermore, the pressure-limited actuation the plunger 12 can also be designed in a different way, namely with mechanical locking elements instead of permanent magnets 23, 24.
