Abstract

My conveyor comprises an associated track-bound car including a drive motor supplied with drive current by current-carrying rails, a container, and a cover for the conveyor, as well as a track on which the conveyor runs by a plurality of stations. In order to prevent unauthorized opening of the cover a latch of a locking mechanism mounted in the track-bound car is restrained in a locked configuration. The latch can be unlocked by an electromagnetic unlocking mechanism mounted in the track-bound car. A very simple control of the unlocking mechanism can be provided, when, at a position or station in the conveyor where it is to be unlocked, an unlocking signal generator is present, which is automatically connectable with the track-bound car, in order to supply the unlocking mechanism with a required unlocking current.

Description

Die Erfindung betrifft eine Förderanlage gemäss Oberbegriff des Anspruches 1.The invention relates to a conveyor system according to the preamble of claim 1.

Eine Förderanlage der eingangs genannten Art ist aus der DE-OS 33 13 951 bekannt. Bei dieser bekannten Förderanlage enthält der Förderwagen eine Steuereinrichtung, in die an einer Sendestation mittels einer Einstelleinrichtung ein Sperrkode eingegeben wird. Die elektromagnetische Entriegelungsvorrichtung bleibt dann so lange gesperrt, bis an einer Empfangsstation der Steuereinrichtung ein Berechtigungskode eingegeben wird. Die Steuereinrichtung vergleicht dann den Berechtigungskode mit dem Sperrkode und betätigt die Entriegelungsvorrichtung nur dann, wenn eine Uebereinstimmung festgestellt worden ist. Diese Art der Verriegelung des Deckels des Behälters ist relativ kompliziert und aufwendig, da an der Sendestation eine Vorrichtung zum Erzeugen und Eingeben eines Sperrkodes und an der Empfangsstation eine Vorrichtung zum Erzeugen und Eingeben eines Berechtigungskodes erforderlich sind. Der Förderwagen selbst benötigt ebenfalls eine relativ komplizierte Steuereinrichtung, um den Sperrkode mit dem Berechtigungskode zu vergleichen.A conveyor system of the type mentioned is known from DE-OS 33 13 951. In this known conveyor system, the trolley contains a control device, into which a blocking code is entered at a transmitting station by means of an adjusting device. The electromagnetic unlocking device then remains locked until an authorization code is entered at a receiving station of the control device. The control device then compares the authorization code with the lock code and actuates the unlocking device only when a match has been found. This type of locking of the lid of the container is relatively complicated and expensive, since a device for generating and entering a blocking code is required at the transmitting station and a device for generating and entering an authorization code is required at the receiving station. The trolley itself also requires a relatively complicated control device to compare the lock code with the authorization code.

Aufgabe der Erfindung ist es, eine Förderanlage der eingangs genannten Art so auszubilden, dass eine Verriegelung des Deckels mit einfacheren Mitteln möglich ist.The object of the invention is to design a conveyor system of the type mentioned at the outset in such a way that the cover can be locked with simpler means.

Die gestellte Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Aufgrund der Vorspannung des Riegels der Verriegelungsvorrichtung bleibt der einmal geschlossene Deckel des Förderwagens geschlossen, bis an den zum Entriegeln bestimmten Stellen der Förderanlage ein Entriegelungsstrom an die Eintriegelungsvorrichtung angelegt wird. An den Sende- und Empfangsstationen genügen lediglich Entriegelungsgeber, die ausserordentlich einfach sein können. Das Merkmal "Entriegelungsgeber" gilt dabei in allgemeinster Form und kann beispielsweise eine reine Stromquelle für den Entriegelungsstrom, ferner Schaltmittel, wie einfache Handschalter, oder auch auf Code ansprechende Schaltmittel beinhalten. Die erfindungsgemässe Anlage zeichnet sich also durch eine ausserordentliche Einfachheit aus, wobei an einer Sendestation weder eine Einstelleinrichtung zum Eingeben eines Sperrkodes noch an einer Empfangsstation eine Einstelleinrichtung zum Eingeben eines Berechtigungskodes und schliesslich auch keine den Sperrkode mit dem Berechtigungskode vergleichende Steuereinrichtung im Förderwagen erforderlich sind.The object is achieved by the characterizing features of claim 1. Due to the pretension of the bolt of the locking device, the once closed remains Cover of the trolley closed until an unlocking current is applied to the locking device at the points of the conveyor system intended for unlocking. At the sending and receiving stations, only unlocking devices are sufficient, which can be extremely simple. The feature "unlocking transmitter" applies here in the most general form and can include, for example, a pure power source for the unlocking current, further switching means, such as simple hand switches, or also switching means responsive to code. The system according to the invention is therefore characterized by an extraordinary simplicity, with neither a setting device for entering a blocking code at a transmitting station nor a setting device for entering an authorization code at a receiving station, and finally also no control device in the trolley that compares the blocking code with the authorization code is required.

Vorteilhafte Ausgestaltungen der Förderanlage sind in den Ansprüchen 2 bis 9 beschrieben.Advantageous embodiments of the conveyor system are described in claims 2 to 9.

Die Einleitung des Entriegelungsstromes an der zum Entriegeln bestimmten Stelle der Förderanlage kann auf verschiedene Weise erfolgen. So ist es möglich, gemäss Anspruch 2 an den Entriegelungsstellen eine zusätzliche Stromschiene anzuordnen, durch welche vom Entriegelungsgeber der Entriegelungsstrom der Entriegelungsvorrichtung eingespeist werden kann. Eine einfachere Lösung hingegen beschreibt Anspruch 3. Hier sind an den Entriegelungsstellen an den Schienen keine zusätzlichen Stromschienen erforderlich, sondern es können direkt die zur Einspeisung des Fahrstromes dienenden Stromschienen auch zur Steuerung der Entriegelungsvorrichtung verwendet werden. Es ist lediglich dafür zu sorgen, dass der Entriegelungsstrom eine von der Spannung des Fahrstromes abweichende Spannung aufweist, die ein Anlaufen des Antriebsmotors verhindert.The unlocking current can be introduced at the point of the conveyor system intended for unlocking in various ways. It is thus possible, according to claim 2, to arrange an additional busbar at the unlocking points, through which the unlocking current of the unlocking device can be fed in by the unlocking transmitter. A simpler solution, on the other hand, is described in claim 3. Here, no additional busbars are required at the unlocking points on the rails, but rather the busbars used to feed the travel current can also be used to control the unlocking device. It is only necessary to ensure that the unlocking current has a voltage which deviates from the voltage of the travel current and which prevents the drive motor from starting.

Dabei kann der Spannungsunterschied gegebenenfalls ausreichend sein, um ein Anfahren des Förderwagens zu verhindern. Gegebenenfalls kann eine zusätzliche Sperrvorrichtung gemäss Anspruch 4 vorhanden sein. Anspruch 5 beschreibt einen vorteilhaften Schaltkreis zur Steuerung der Entriegelungsvorrichtung, der besonders einfach und preisgünstig herstellbar ist. Um auszuschliessen, dass sich kurzzeitige Spannungsschwankungen des Fahrstromes auf die Entriegelungsvorrichtung auswirken, ist eine Ausgestaltung nach Anspruch 6 von Vorteil. Gemäss Anspruch 7 kann auch die Sperrvorrichtung für den Fahrstrom des Antriebsmotors in den Schaltkreis der Entriegelungsvorrichtung integriert sein.The voltage difference may be sufficient to prevent the trolley from starting up. If necessary, an additional locking device can be present. Claim 5 describes an advantageous circuit for controlling the unlocking device, which is particularly simple and inexpensive to manufacture. In order to rule out that brief voltage fluctuations in the travel current have an effect on the unlocking device, an embodiment according to claim 6 is advantageous. According to claim 7, the blocking device for the driving current of the drive motor can also be integrated in the circuit of the unlocking device.

Um zu verhindern, dass ein Förderwagen an jeder Stelle der Förderanlage, die einen Entriegelungsgeber aufweist, anspricht, kann es zweckmässig sein, die Anlage nach Anspruch 8 weiterzubilden. Dann kann ein Entriegelungsgeber nur dann aktiviert werden, wenn der Kode am Förderwagen dem Stationsspezifischen Kode entspricht, auf den die Kodeleseeinrichtung eingestellt ist.In order to prevent a trolley from responding at any point in the conveyor system which has an unlocking sensor, it can be expedient to further develop the system according to claim 8. Then an unlocking device can only be activated if the code on the trolley corresponds to the station-specific code to which the code reading device is set.

Die Verriegelungsvorrichtung ist zweckmässigerweise nach Anspruch 9 ausgestaltet, so dass das Schliessen des Deckels auch bei fehlendem Entriegelungsstrom möglich ist.The locking device is expediently designed according to claim 9, so that the lid can be closed even when there is no unlocking current.

Ausführungsbeispiele des Gegenstandes der Erfindung werden nachfolgend anhand der Zeichnungen näher beschrieben, dabei zeigen:

  • Figur 1 einen Querschnitt durch einen an einer Station stehenden Förderwagen;
  • Figur 2 die Verriegelungsvorrichtung in um 90 geschwenkter Ansicht;
  • Figur 3 ein Schaltschema für den Antriebsmotor und die Entriegelungsvorrichtung; und
  • Figur 4 die Steuerung einer Entriegelungsvorrichtung mittels einer dritten Stromschiene.
Exemplary embodiments of the subject matter of the invention are described in more detail below with reference to the drawings, in which:
  • 1 shows a cross section through a trolley standing at a station;
  • Figure 2 shows the locking device in a pivoted view by 90;
  • Figure 3 is a circuit diagram for the drive motor and the unlocking device; and
  • Figure 4 shows the control of an unlocking device by means of a third busbar.

Die Figur 1 zeigt eine Station einer schienengebundenen Förderanlage im Querschnitt. Der Förderwagen 2 weist einen mit einem Deckel 4 verschliessbaren Behälter 6 auf, der lösbar oder fest mit einem Fahrgestell 8 verbunden ist. Dieses enthält Lauf- bzw. Treibrollen 10, die auf einer Schiene 12 laufen, die beispielsweise die Rollen übergreifende Seitenteile 14 enthält, sodass der Förderwagen 2 in jeder Stellung, auch über Kopf, sicher in den Schienen gehalten ist. An der Schiene 12 sind Stromschienen 16, 18 angeordnet, an denen Stromabnehmer 20, 22 zur Speisung des Antriebsmotors 24 mit Fahrstrom angreifen. An einer Seite des Behälters 6 sind in Fahrtrichtung weisende Führungsleisten 26, 28, 30 übereinander angeordnet, in denen Kodeelemente 32, 34, 36 in Form von Permanentmagneten verschiebbar geführt sind. Mittels der Kodeelemente können verschiedene Kode am Förderwagen eingestellt werden, die insbesondere zur Zielkennzeichnung des Förderwagens oder für andere Aufgaben dienen können. Diese an den Förderwagen eingestellten Kode werden mittels Kodeleseeinrichtungen 38 gelesen, die längs des Streckenverlaufes der Förderanlage angeordnet sind und verschiedenen Aufgaben dienen, so beispielsweise zum Steuern von Weichen, Entriegelungsvorrichtungen usw.Figure 1 shows a station of a rail-bound conveyor system in cross section. The trolley 2 has a container 6 which can be closed with a lid 4 and which is detachably or permanently connected to a chassis 8. This contains running or driving rollers 10, which run on a rail 12, which contains, for example, side parts 14 that overlap the rollers, so that the trolley 2 is securely held in the rails in any position, even overhead. Busbars 16, 18 are arranged on the rail 12, on which current collectors 20, 22 act to supply the drive motor 24 with traction current. On one side of the container 6, guide strips 26, 28, 30 are arranged one above the other in the direction of travel, in which code elements 32, 34, 36 are displaceably guided in the form of permanent magnets. The code elements can be used to set various codes on the trolley, which can be used, in particular, to identify the trolley or for other tasks. These codes set on the trolleys are read by means of code reading devices 38, which are arranged along the route of the conveyor system and serve various purposes, for example for controlling switches, unlocking devices, etc.

Wie insbesondere aus den Figuren 1 und 2 hervorgeht, weist der Deckel 4 einen umlaufenden Absatz 40 auf, mit dem er auf dem oberen Behälterrand 42 aufsitzt. An den Absatz 40 schliesst sich nach aussen eine Schürze 44 an, die den Behälter 6 übergreift. An einer Seite des Behälters ist der Deckel 4 über ein Scharnier 46 verschwenkbar mit dem Behälter 6 verbunden. An der gegenüberliegenden Seite ist eine selbsteinrastende Verriegelungsvorrichtung 48 angeordnet, um den Deckel 4 in geschlossener Stellung zu halten und gegen unbefugtes Oeffnen zu sichern.As can be seen in particular from FIGS. 1 and 2, the lid 4 has a circumferential shoulder 40 with which it sits on the upper edge of the container 42. An apron 44 adjoins the shoulder 40 and overlaps the container 6. On one side of the container is the Lid 4 is pivotally connected to the container 6 via a hinge 46. A self-locking locking device 48 is arranged on the opposite side in order to hold the cover 4 in the closed position and to secure it against unauthorized opening.

Die Verriegelungsvorrichtung 48 weist einen Riegel 50 auf, der an einem mit der Wandung 52 des Behälters 6 verbundenen Zapfen 54 verschwenkbar gelagert ist. Der Riegel 50 ist als Kniehebel ausgebildet, wobei ein Helbel 56 eine Nase 58 besitzt, die in Verriegelungsstellung einen Zapfen 60 übergreift, der an der Schürze 44 des Deckels 4 befestigt ist und über eine Ausnehmung 62 in der Wandung 52 des Behälters 6 ins Innere des Behälters ragt. Am zweiten Hebel 64 des Riegels 50 ist eine Zugfeder 66 angeschlossen, die den Riegel in die in Figur 1 gezeigte Verriegelungsstellung vorspannt. Die Nase 58 enthält eine schräge Auflauffläche 68, an der der Zapfen 60 des Deckels 4 beim Schliessen des Deckels angreift und den Riegel 50 entgegen der Kraft der Zugfeder 66 aus der Verriegelungsstellung verdrängt, sodass der Riegel selbsteinrastend ist. Anschläge 70, 72 dienen zur Begrenzung des Schwenkweges des Riegels 50.The locking device 48 has a bolt 50 which is pivotably mounted on a pin 54 connected to the wall 52 of the container 6. The latch 50 is designed as a toggle lever, with a lever 56 having a nose 58 which, in the locked position, engages over a pin 60 which is fastened to the apron 44 of the lid 4 and via a recess 62 in the wall 52 of the container 6 into the interior of the Container protrudes. A tension spring 66 is connected to the second lever 64 of the bolt 50 and biases the bolt into the locking position shown in FIG. 1. The nose 58 contains an oblique run-up surface 68, on which the pin 60 of the cover 4 engages when the cover is closed and displaces the bolt 50 against the force of the tension spring 66 from the locking position, so that the bolt is self-engaging. Stops 70, 72 serve to limit the swivel path of the bolt 50.

An dem Riegel 50 greift weiter eine Entriegelungsvorrichtung 74 an, die einen Elektromagneten 76 aufweist, dessen Kern 78 über eine Koppelstange 80 mit dem Hebel 64 des Riegels 50 gelenkig verbunden ist. Der Elektromagnet 76 ist über eine Leitung 82 mit einem Schaltkreis 84 verbunden, der an die Stromschienen 16, 18 angeschlossen ist und in erster Linie zum Aktivieren des Elektromagneten 76 dient und im vorliegenden Beispiel zusätzlich zum Abschalten des Fahrstromes für den Antriebsmotor 24, wenn ein Entriegelungsstrom angelegt wird. An die Stromschienen 16, 18 wird von einer nicht näher dargestellten Stromquelle ein Fahrstrom beispielssweise mit einer Spannung von 24 Volt Gleichstrom angelegt. Zur Steuerung der Entriegelungsvorrichtung 74 dient ein ortsfester Entriegelungsgeber 86, der über Leitungen 88 einen Entriegelungsstrom an die Stromschienen 16, 18 abgibt. Dieser Entriegelungsstrom weist eine Spannung auf, die kleiner ist als die Spannung des Fahrstromes und beispielsweise 7 Volt Gleichstrom beträgt.An unlocking device 74, which has an electromagnet 76, the core 78 of which is articulated via a coupling rod 80 to the lever 64 of the bolt 50, also acts on the bolt 50. The electromagnet 76 is connected via a line 82 to a circuit 84 which is connected to the busbars 16, 18 and serves primarily to activate the electromagnet 76 and, in the present example, also to switch off the travel current for the drive motor 24 when an unlocking current is present is created. A traction current, for example, is supplied to the busbars 16, 18 by a power source (not shown in detail) a voltage of 24 volts DC is applied. To control the unlocking device 74, a stationary unlocking transmitter 86 is used, which delivers an unlocking current to the busbars 16, 18 via lines 88. This unlocking current has a voltage that is less than the voltage of the traction current and is, for example, 7 volts DC.

Der Aufbau des im vorliegenden Beispiel zur Verarbeitung des Fahrstromes für den Antriebsmotor und des Entriegelungsstromes für die Entriegelungsvorrichtung dienenden Schaltkreises 84 ist in Figur 3 näher dargestellt. Ein Stromabnehmer 20 ist direkt über eine Leitung 90 mit dem Antriebsmotor 24 verbunden. In der den Stromabnehmer 22 mit dem Antriebsmotor verbindenden Leitung 92 liegt ein, von einem Relais 94 gesteuerter Schalter 942. In Ruhestellung ist der Schalter 942 geöffnet bzw. stellt die Verbindung zu einer Kurzschlussleitung 96 her, um den vorzugsweise permanenterregten Antriebsmotor in gebremster Stellung zu halten. Der Schaltkreis 84 ist über einen Brückengleichrichter 98 an den Leitungen 90, 92 angeschlossen. Der Schaltkreis 84 bildet auch eine Sperrvorrichtung für den Stromkreis des Antriebsmotors und enthält das über eine Zenerdiode 100 angeschlossene Relais 94, wobei die Zenerdiode für Ströme mit einer Spannung unterhalb der Spannung des Fahrstromes nichtleitend ist, sodass das Relais 94 nur bei Auftreten eines Stromes mit der Spannung des Fahrstromes aktiviert wird, sodass auch nur dann der Schalter 942 geschlossen werden kann und der Antriebsmotor 24 aktiviert wird. Bei einem Strom mit einer Spannung unterhalb der Spannung des Fahrstromes, wie dies für den Entriegelungsstrom zutrifft, bleibt das Relais 94 in Ruhestellung. Parallel zur Zenerdiode 100 und Relais 94 ist ein weiterer Stromkreis 102 vorhanden, in dem der Elektromagnet 76 liegt und der durch einen weiteren Schalter 941 des Relais 94 geschaltet wird.The structure of the circuit 84 serving in the present example for processing the travel current for the drive motor and the unlocking current for the unlocking device is shown in more detail in FIG. A current collector 20 is connected directly to the drive motor 24 via a line 90. In the current collector 22 with the drive motor connecting line 92 is an, controlled by a relay 94 switch 94. 2 In the rest position, the switch 94 2 is open or establishes the connection to a short-circuit line 96 in order to keep the preferably permanently excited drive motor in the braked position. The circuit 84 is connected to the lines 90, 92 via a bridge rectifier 98. The circuit 84 also forms a blocking device for the circuit of the drive motor and contains the relay 94 connected via a zener diode 100, the zener diode being non-conductive for currents with a voltage below the voltage of the travel current, so that the relay 94 only with the occurrence of a current with the Voltage of the traction current is activated, so that the switch 94 2 can only be closed and the drive motor 24 is activated. In the case of a current with a voltage below the voltage of the travel current, as is the case for the unlocking current, the relay 94 remains in the rest position. In parallel to the zener diode 100 and relay 94 there is another circuit 102 in which the electromagnet 76 is located and which is switched by a further switch 94 1 of the relay 94.

In Ruhestellung des Relais 94 ist der Schalter 941 geschlossen, sodass beim Auftreten des Entriegelungsstromes der Elektromagnet 76 anzieht, wodurch der Riegel 50 entriegelt wird. Parallel zum Elektromagnet 76 kann ein weiterer Elektromagnet 761 einer weiteren Entriegelungsvorrichtung für einen weiteren Riegel vorgesehen sein, wie dies gestrichelt in Figur 3 angedeutet ist. Der Schaltkreis 84 enthält überdies im Stromkreis 102 ein Verzögerungsglied 104, um ein Abfallen des Elektromagneten 76 bei kurzzeitigem Absinken der Fahrbetriebsspannung zu verhindern.In the rest position of the relay 94, the switch 94 1 is closed, so that the electromagnet 76 picks up when the unlocking current occurs, as a result of which the bolt 50 is unlocked. In parallel to the electromagnet 76, a further electromagnet 76 1 of a further unlocking device for a further bolt can be provided, as is indicated by dashed lines in FIG. 3. The circuit 84 also contains a delay element 104 in the circuit 102 in order to prevent the electromagnet 76 from falling if the driving operating voltage drops briefly.

Die Figur 3 zeigt weiter das Schaltschema eines Entriegelungsgebers 86, der im wesentlichen aus einer Stromquelle 106 mit einer Entriegelungsspannung vom 7 Volt Gleichstrom gebildet ist. Im gezeigten Beispiel enthält der Entriegelungsgeber 86 noch eine Kodeleseeinrichtung 38, die im wesentlichen aus in Serie geschalteten Reedschaltern 108, 110, 112 besteht. Diese Reedschalter sind in einem stationsspezifischen Kode fest eingestellt. Jeder Reedschalter spricht auf ein Kodeelement 32, 34, 36 an, das am Förderwagen angeordnet ist. Nur wenn die Kodeelemente 32, 34, 36 in dem stationsspezifischen Kode angeordnet sind, können alle drei Reedschalter 108, 110, 112 schliessen und der Entriegelungsgeber 86 einen Entriegelungsstrom an die Stromschienen 16, 18 abgeben. Für einfache Anwendungsfälle kann die Kodeleseeinrichtung 38 in der Regel entfallen, sodass an den Stromschienen 16, 18 ein permanenter Entriegelungsstrom ansteht. Gegebenenfalls kann der Entriegelungsgeber 86 einen nicht näher dargestellten Schalter enthalten, mit welchem der Entriegelungsgeber 86 nach Bedarf von Hand und/oder durch andere nicht dargestellte Schaltelemente aktiviert werden kann.FIG. 3 also shows the circuit diagram of an unlocking transmitter 86, which is essentially formed from a current source 106 with an unlocking voltage of 7 volts DC. In the example shown, the unlocking transmitter 86 also contains a code reading device 38, which essentially consists of reed switches 108, 110, 112 connected in series. These reed switches are permanently set in a station-specific code. Each reed switch responds to a code element 32, 34, 36 which is arranged on the trolley. Only if the code elements 32, 34, 36 are arranged in the station-specific code can all three reed switches 108, 110, 112 close and the unlocking transmitter 86 deliver an unlocking current to the busbars 16, 18. For simple applications, the code reading device 38 can generally be dispensed with, so that a permanent unlocking current is present on the busbars 16, 18. Optionally, the unlocking transmitter 86 can contain a switch, not shown, with which the unlocking transmitter 86 can be activated by hand and / or by other switching elements, not shown, as required.

Die Figur 4 zeigt ein weiteres Ausführungsbeispiel der Steuerung der Verriegelungsvorrichtung 48, wobei die Schiene 12 neben den Stromschienen 16, 18 noch eine dritte von einem Stromabnehmer 116 des Förderwagens abgetastete Stromschiene 114 aufweist, die zur Steuerung der Entriegelungsvorrichtung 74 dient. Hierzu ist der Entriegelungsgeber 86 mit der dritten Stromschiene 114 und eine der beiden anderen Stromschienen, die als Masse dient, verbunden. Der Elektromagnet 76 der Entriegelungsvorrichtung 74 kann dann direkt mit der dritten Stromschiene 114 und der weiteren Stromschiene 18 verbunden sein, sodass der Schaltkreis 84 entfällt.FIG. 4 shows a further exemplary embodiment of the control of the locking device 48, the rail 12 in addition to the busbars 16, 18 also having a third busbar 114 which is scanned by a current collector 116 of the trolley and which is used to control the unlocking device 74. For this purpose, the unlocking sensor 86 is connected to the third busbar 114 and one of the other two busbars, which serves as a ground. The electromagnet 76 of the unlocking device 74 can then be connected directly to the third busbar 114 and the further busbar 18, so that the circuit 84 is omitted.

Die vorliegende Verriegelungsvorrichtung kann als ausschliessliche und einzige Verriegelungsvorrichtung des Deckels dienen oder als zusätzliche Sicherungsvorrichtung zu einem bestehenden Schliessmechanismus üblicher Art oder zu einem solchen gemäss der DE-OS 34 11 143.The present locking device can serve as the exclusive and only locking device of the cover or as an additional securing device for an existing locking mechanism of the usual type or for one according to DE-OS 34 11 143.

Im Gegensatz zum gezeigten Ausführungsbeispiel kann die Sperrvorrichtung für den Stromkreis des Antriebsmotors nicht Bestandteil des Schaltkreises der Entriegelungsvorrichtung sein, sondern Bestandteil eines Schaltkreises, der den exakten Verschluss des Deckels mittels einer normalen Schliessvorrichtung überwacht, so wie dies in den CH-PSen 528 388 und 607 976 beschrieben ist. Der in Figur 3 beschriebene Schalter 942 kann dann durch ein Schaltelement eines solchen Schaltkreises betätigt werden.In contrast to the exemplary embodiment shown, the locking device for the circuit of the drive motor cannot be part of the circuit of the unlocking device, but part of a circuit that monitors the exact closure of the cover by means of a normal locking device, as is described in CH-PSs 528 388 and 607 976. The switch 94 2 described in FIG. 3 can then be actuated by a switching element of such a circuit.
