Description

Technisches GebietTechnical field

Gegenstand der Erfindung ist ein motorischer Verschluß für Geräte mit einer Tür, die eine umlaufende elastische Dichtung aufweist.The invention relates to a motorized closure for devices with a door that a has circumferential elastic seal.

Stand der TechnikState of the art

Bei Geräten oder Schränken mit heißer Atmosphäre oder Heißdampfentwicklung muß dafür gesorgt werden, daß die Tür gegen die Kraft einer elastischen Dichtung fest verschlossen werden kann.
Man unterscheidet dabei zwei Schließzustände: Die angelehnte Tür, die einen evtl. Ausgleich eines Überdrucks erlaubt und die Verriegelung unter Druck.
Bei Verschlüssen mit Drehfalle oder Keilhebel muß der Benutzer erhebliche Kräfte aufbringen und zumindest eine Hand frei haben.In the case of devices or cabinets with a hot atmosphere or hot steam generation, it must be ensured that the door can be closed firmly against the force of an elastic seal.
A distinction is made between two closed states: the ajar door, which allows compensation of overpressure and the locking under pressure.
In the case of closures with a rotary latch or wedge lever, the user must exert considerable forces and have at least one hand free.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, die Bedienung zu erleichtern und unabhängig von der Qualität und Abnutzung der Dichtung einen gleichmäßigen Schließdruck zu gewährleisten.
Diese Aufgabe wird bei einem motorischen Verschluß der eingangs genannten Art dadurch gelöst, daß ein türseitiger Kloben, der eine Querbohrung aufweist, in eine Greifzange eintaucht, die aus zwei durch ein Lager verbundenen Zangenhälften besteht, zwischen denen ein mit Langloch versehener und motorisch angetriebener Steuerschieber gelagert ist, wobei dieser in einer Endlage die Zangenöffnung freigibt und in der anderen diese Zange und den Kloben blockiert, so daß der Motor die Tür mit einstellbarer Kraft gegen das Gehäuse zu ziehen vermag.The invention has for its object to facilitate operation and to ensure a uniform closing pressure regardless of the quality and wear of the seal.
This object is achieved in a motorized closure of the type mentioned in that a door-side block, which has a transverse bore, is immersed in a gripper which consists of two pliers halves connected by a bearing, between which a slotted hole and a motor-driven control slide is mounted is, which in one end position releases the pliers opening and blocks these pliers and the block in the other, so that the motor can pull the door against the housing with adjustable force.

In Fig. 1 ist mit 1 ein Kloben bezeichnet, der zwischen die Hälften 2a, 2b einer Greifzange 2 ragt.
Die Teile 2a, 2b stellen zweiarmige Hebel dar, die über angeformte Lagerböcke 2a1, 2b1 und einen Bolzen 3 miteinander verbunden sind. In einer Aussparung der Teile 2a, 2b liegt zwischen den Lagerböcken 2a1 und 2b1 ein Steuerschieber 4, dessen Langloch 4a über den Bolzen 3 greift.
Am rechten Ende der Teile 2a, 2b ist eine leichte Schraubenfeder 5 eingespannt, die die Greifzange 2 am linken Ende zusammendrückt. Die eigentlichen Greifelemente sind Kegelstümpfe 2a2 und 2b2, die in eine Aussparung 1a des Klobens 1 passen.In Fig. 1 , 1 denotes a block which projects between the halves 2a, 2b of a gripper 2.
The parts 2a, 2b represent two-armed levers which are connected to one another via molded-on bearing blocks 2a1, 2b1 and a bolt 3. In a recess in the parts 2a, 2b there is a control slide 4 between the bearing blocks 2a1 and 2b1, the elongated hole 4a of which extends over the bolt 3.
At the right end of the parts 2a, 2b, a light coil spring 5 is clamped, which compresses the gripping pliers 2 at the left end. The actual gripping elements are truncated cones 2a2 and 2b2, which fit into a recess 1a in the block 1.

Wenn man den Kloben 1 nach rechts schiebt, rastet die Zange 2 ein, wie es in Fig. 2 dargestellt ist. Der Kloben 1 wird dabei mit einer Kraft festgehalten, die durch die Kenndaten der Feder 5 vorgegeben ist.If you push the block 1 to the right, the pliers 2 snap into place, as shown in Fig. 2 . The block 1 is held with a force that is predetermined by the characteristics of the spring 5.

Wenn man jetzt den Steuerschieber 4 nach rechts zieht, wie es in Fig. 3 dargestellt ist, wandert die verbreiterte Steuerfläche 4c zwischen die Schultern der Zange 2. Diese kann jetzt nicht mehr zusammengedrückt werden, so daß der Kloben 1 ganz sicher festgehalten wird.If you now pull the control slide 4 to the right, as shown in Fig. 3 , the widened control surface 4c moves between the shoulders of the pliers 2. This can no longer be pressed together, so that the block 1 is held securely.

In Fig. 4 wird gezeigt, wie die Einheit aus Kloben 1 und Greifzange 2 mit Hilfe des Steuerschiebers 4 nach rechts gezogen wurde, um die Türdichtung fest anzupressen. Der Anpreßdruck wird durch den Motor bestimmt, der ein einstellbares Abschaltmoment aufweist. In Fig. 4 it is shown how the unit consisting of the clamp 1 and gripper 2 was pulled to the right with the aid of the control slide 4 in order to firmly press the door seal. The contact pressure is determined by the motor, which has an adjustable switch-off torque.

Die Öffnung des Schrankes verläuft wie folgt:
Wenn der Motor durch einen Öffnungsimpuls umgesteuert wird, wandert die beschriebene Einheit nach links, bis der von der Dichtung ausgeübte Druck ausgeglichen ist. Anschließend läuft der Steuerschieber 4 in seine linke Endstellung, die in Fig. 2 gezeichnet ist. In dieser entriegelten Stellung kann die Tür mit dem Kloben 1 leicht aufgezogen werden, wie es Fig. 1 zeigt.
In Fig. 5 ist die Zangenhälfte 2b in Draufsicht dargestellt. Man erkennt unten den Kegelstumpf 2b2, im mittleren Bereich die Lagerböcke 2b1 und am oberen Rand Stifte 2b3, die zwei gleiche Schraubenfedern aufnehmen.The opening of the cabinet is as follows:
If the motor is reversed by an opening pulse, the described unit moves to the left until the pressure exerted by the seal is balanced. The control slide 4 then runs into its left end position, which is drawn in FIG. 2 . In this unlocked position, the door can be easily opened with the block 1, as shown in FIG. 1 .
5 shows the pliers half 2b in a top view. The truncated cone 2b2 can be seen at the bottom, the bearing blocks 2b1 in the central region and pins 2b3 at the upper edge, which receive two identical coil springs.

Fig. 6 zeigt die Greifzange 2 in auseinandergezogener Darstellung. Jede Zangenhälfte ist mit zwei Lagerböcken 2a1 und 2b1 ausgestattet, die kammartig ineinandergreifen und dadurch außerordentlich stabil sind. Der Bolzen 3 ist nicht nur Lagerbolzen, sondern auch Halt und Führung für den Steuerschieber 4, dessen Relativbewegung durch das Langloch 4a begrenzt ist. Fig. 6 shows the gripping pliers 2 in an exploded view. Each pliers half is equipped with two pedestals 2a1 and 2b1, which mesh like a comb and are therefore extremely stable. The bolt 3 is not only a bearing bolt, but also a support and guide for the control slide 4, the relative movement of which is limited by the elongated hole 4a.

In Fig. 7 ist das Teil 2a und der Steuerschieber 4 in Seitenansicht gezeichnet. Außer dem Lagerbock 2a1 und dem Kegelstumpf 2a2 erkennt man einen Stift 2a3 als Führungselement für eine Feder 5.
Der Steuerschieber 4 weist außer dem Langloch 4a Befestigungslöcher 4b für die Zugstange 6 auf.In Fig. 7 the part 2a and the spool 4 is drawn in side view. In addition to the bearing block 2a1 and the truncated cone 2a2, a pin 2a3 can be seen as a guide element for a spring 5.
The control slide 4 has, in addition to the elongated hole 4a, fastening holes 4b for the pull rod 6.

In Fig. 8 - 10 ist diese Zugstange 6 in verschiedenen Betriebszustanden zu sehen. Das linke Ende der Stange wird über die Löcher 6a mit dem Steuerschieber 4 verbunden, das rechte ist über einen abgewinkelten Schlitz 6b mit einer in Fig. 10 dargestellten Getriebemotoreinheit 7 gekuppelt. Das Abtriebsrad 8 dieser Einheit trägt einen Exzenterstift 9, der in dem Langloch 10a einer Kulisse 10 gleitet. Am linken Ende weist diese Kulisse einen Kupplungsstift 10b auf, der in dem Schlitz 6b gleitet. Schlitz und Kupplungsstift dienen als Notauslöser für den Verschluß.
Fig. 8 zeigt die Anordnung im Zustand der Notentriegelung, Fig. 9 die Lage der Teile bei geschlossener Tür.
Wenn man zwecks Notentriegelung die unter Zugspannung stehende Stange 6 in Richtung des Pfeiles 11 nach oben drückt, wird der Stift 10b freigegeben, die Stange 6 kann nach links ausweichen und die Zange 2 gibt den Kloben 1 frei.
Soll die Tür nach einer Notentriegelung geschlossen werden , muß der Motor zunächst einen Öffnungsimpuls erhalten. Daraufhin wandert die Kulisse 10 nach links, bis der Stift 10b die Raststellung in dem abgewinkelten Schlitz 6b einnimmt. Dabei fällt die Stange 6 entweder durch ihr Eigengewicht nach unten, oder das Einrasten wird durch eine Feder bewirkt.
In Fig. 10 nimmt die Stange 6 und die Kulisse 10 die linke Endstellung ein, in der die Tür offen oder zur Öffnung vorbereitet ist. Wenn der Motor 13 in Schließrichtung anläuft, wird das Abtriebszahnrad 8 über die Zahnräder 14, 15, 16 in Richtung des Pfeiles 12 bewegt. Der Exzenterstift 9 zieht dabei die Kulisse 10 mit der Stange 6 nach rechts, bis eine bestimmte Schließkraft erreicht ist und der Zustand Fig. 9 entspricht.
Je nach Zustand der Dichtung kann der Drehwinkel des Rades 8 zwischen 100 und etwa 170° liegen.
Durch Feineinstellung wird man einen Winkel zwischen 150 und 170° bevorzugen, weil man dann mit kleinerem Motordrehmoment eine größere Schließkraft erreicht.
Da die Zahnräder 14, 15 als Schneckengetriebe ausgebildet sind, ist der Antrieb selbsthemmend. Ein Sensor für die Stromaufnahme bewirkt, daß sich der Motor beim Erreichen einer gewünschten Schließkraft ausschaltet.
Der Verriegelungsbefehl für den Getriebemotor kann von einem Törkontakt, einem am Schrank oder im Fußbereich angeordneten Taster oder von einer Programmsteuerung ausgehen. Ist bei Erteilung des Verriegelungsbefehls der Kloben nicht in die Greifzange eingefahren, läuft der Motor bis zur Endstellung der Zugstange durch. Da aber kein Stromanstieg erfolgt, wird das Ausbleiben dieses Signals von der Steuerung dazu benutzt, die Zugstange wieder in die Entriegelungsstellung zu bringen.
Zur Öffnung wird die Motorspannung umgepolt. 8-10 , this pull rod 6 can be seen in different operating states. The left end of the rod is connected to the control spool 4 via the holes 6a, and the right end is coupled to a geared motor unit 7 shown in FIG. 10 via an angled slot 6b. The driven wheel 8 of this unit carries an eccentric pin 9 which slides in the slot 10a of a link 10. At the left end, this link has a coupling pin 10b which slides in the slot 6b. Slot and coupling pin serve as an emergency release for the closure.
Fig. 8 shows the arrangement in the state of the emergency release, Fig. 9 shows the position of the parts with the door closed.
If one pushes the rod 6 under tension in the direction of arrow 11 for emergency release, the pin 10b is released, the rod 6 can move to the left and the pliers 2 release the block 1.
If the door is to be closed after an emergency release, the motor must first receive an opening impulse. The setting 10 then moves to the left until the pin 10b assumes the latching position in the angled slot 6b. The rod 6 either falls down due to its own weight, or the engagement is effected by a spring.
In Fig. 10 , the rod 6 and the backdrop 10 assume the left end position, in which the door is open or prepared for opening. When the motor 13 starts in the closing direction, the driven gear 8 is moved in the direction of the arrow 12 via the gears 14, 15, 16. The eccentric pin 9 pulls the link 10 with the rod 6 to the right until a certain closing force is reached and the state corresponds to FIG. 9 .
Depending on the condition of the seal, the angle of rotation of the wheel 8 can be between 100 and approximately 170 °.
By fine adjustment, an angle between 150 and 170 ° will be preferred, because then a greater closing force can be achieved with a smaller motor torque.
Since the gears 14, 15 are designed as worm gears, the drive is self-locking. A sensor for the current consumption causes the motor to switch off when a desired closing force is reached.
The locking command for the geared motor can come from a door contact, a button on the cabinet or in the foot area or from a program control. If the clamp is not inserted into the gripper when the locking command is issued, the motor runs through to the end position of the pull rod. However, since there is no current increase, the absence of this signal is used by the control to bring the pull rod back into the unlocked position.
The motor voltage is reversed for opening.

Fig.11 zeigt die Antriebseinheit von oben. Der relativ kleine Motor 13 ist leicht schräg angeordnet. Sein Schneckenrad 14 greift in das Rad 15 ein.
Die Länge der Stange 6 ist beliebig. So kann die Antriebseinheit weit hinten im Gehäuse angeordnet werden, wo schädliche Einflüsse durch Hitze oder Feuchtigkeit auszuschließen sind.
Je nach Größe der Tür kann man 1, 2 oder 3 motorische Verschlüsse übereinander anordnen und synchron steuern. Fig. 11 shows the drive unit from above. The relatively small motor 13 is arranged slightly obliquely. His worm wheel 14 engages with the wheel 15.
The length of the rod 6 is arbitrary. The drive unit can be located far back in the housing, where harmful effects from heat or moisture can be excluded.
Depending on the size of the door, 1, 2 or 3 motorized locks can be arranged one above the other and controlled synchronously.

Gewerbliche VerwertbarkeitCommercial usability

Der beschriebene Türverschluß ist dazu bestimmt, bei Heißgeräten oder auch anderen technischen Apparaten, wie z.B. Zentrifugen, eingesetzt zu werden.
Besonders vorteilhaft ist dabei, daß der Bedienende die Hände frei hat.
Die Wartungsintervalle für das System sind sehr groß, weil die der Hitze oder besonderen Atmosphäre ausgesetzte Greifzange keine empfindlichen Teile aufweist und weil die alternde Dichtung immer mit konstanter Schließkraft angepreßt wird. The door lock described is intended to be used in hot appliances or other technical devices such as centrifuges.
It is particularly advantageous that the operator has his hands free.
The maintenance intervals for the system are very long because the gripping pliers, which are exposed to heat or a special atmosphere, have no sensitive parts and because the aging seal is always pressed with constant closing force.
