Description

Die Erfindung betrifft ein selbsttätiges Tor mit zwei Torteilen aus aufwickelbaren Bahnen, die zum Schließ- und Öffnungsvorgang symmetrisch zueinander in horizontaler Richtung beweglich sind, mit senkrecht stehenden Aufwickelwalzen für die Bahnen, die beidseits der Toröffnung angeordnet sind, mit je einer Schiene an den beim Schließvorgang vorderen Bahnenden, die von angetriebenen, über der Toröffnung auf Schienen beweglichen Laufkatzen geführt sind.The invention relates to an automatic gate with two gate parts made of windable webs, which are symmetrically movable to each other in the horizontal direction for the closing and opening process, with vertical winding rollers for the webs, which are arranged on both sides of the door opening, each with a rail to the closing process front ends of the track, which are guided by driven trolleys which can move over the gate opening on rails.

Ein selbsttätiges Tor dieser Gattung ist durch die DE-A-26 25 927 bekanntgeworden. Dabei ist oberhalb der Toröffnung eine Schienenanordnung mit Zuggurten vorgesehen, die je auf eine Laufkatze einwirken. Diese Laufkatze trägt das vordere Bahnende. Um zu verhindern, daß bei der Schließ- oder Öffnungsbewegung Klemmerscheinungen auftreten, ist auch am unteren Ende der Bahnenden eine Riemen- oder Gurtanordnung vorgesehen, die ebenfalls das vordere Bahnende führt. Die untere Riemenanordnung wird dabei über die Aufwickelwalzen angetrieben.An automatic gate of this type has become known from DE-A-26 25 927. A rail arrangement with tension belts is provided above the gate opening, each of which acts on a trolley. This trolley carries the front end of the track. In order to prevent clamping phenomena from occurring during the closing or opening movement, a belt or belt arrangement is also provided at the lower end of the web ends, which also guides the front web end. The lower belt arrangement is driven by the winding rollers.

Tore der eingangs angegebenen Gattung dienen beispielsweise dazu, einzelne Werk- oder Lagerhallen voneinander zu trennen. Soll das Tor durch Transportfahrzeuge oder dergleichen passiert werden, öffnen sich die Tore selbsttätig, wobei die Tore durch geeignete Motoren angetrieben werden. Um die Öffnungszeit möglichst kurz zu halten, sind sehr rasche Torbewegungen erwünscht. Werden die Öffnungsbewegungen nur am oberen Ende der Toröffnung in das Tor eingeleitet, besteht die Gefahr einer Verkantung des Tores. Die Verwendung von zusätzlichen Führungselementen am Boden hat nun den Nachteil, daß diese Führungselemente bei der Tordurchfahrt stören. Werden diese Einrichtungen in den Boden eingesenkt, besteht die Gefahr der Verschumtzung, was zu Störungen führen kann.Gates of the type specified at the beginning are used, for example, to separate individual workshops or warehouses. If the gate is to be passed by transport vehicles or the like, the gates open automatically, the gates being driven by suitable motors. In order to keep the opening time as short as possible, very rapid door movements are desirable. If the opening movements are only introduced into the door at the upper end of the door opening, there is a risk of the door tilting. The use of additional guide elements on the floor now has the disadvantage that these guide elements interfere with the passage of the gate. If these devices are sunk into the ground, there is a risk of contamination, which can lead to faults.

In der FR-E-15 848 ist ein Torverschluß beschrieben, der aus einzelnen Lamellen besteht, die seitlich der Toröffnung aufwickelbar sind. Bei dieser Bauweise fehlt eine untere Führung der Torlamellen. Dieses Tor ist jedoch kein selbsttätiges Tor, und die Torbewegung erfolgt offenbar sehr langsam, so daß zwar die vorgesehene Führung ausreicht, eine rasche Toröffnung jedoch nicht möglich ist.FR-E-15 848 describes a gate lock that consists of individual slats that can be wound up to the side of the gate opening. With this design, there is no lower guide for the door slats. However, this gate is not an automatic gate, and the gate movement is obviously very slow, so that although the intended guidance is sufficient, rapid gate opening is not possible.

Der Erfindung liegt die Aufgabe zugrunde, ein selbsttätiges Tor der eingangs angegebenen Gattung dahingehend weiterzuentwickeln, daß es möglich ist, eine rasche Torbewegung zu erreichen, ohne daß Führungsmittel auf dem Fußboden die Durchfahrt oder den Durchtritt durch das Tor behindern.The invention has for its object to further develop an automatic gate of the type specified in such a way that it is possible to achieve a rapid gate movement without guide means on the floor hindering the passage or passage through the gate.

Die Erfindung löst die gestellte Aufgabe dadurch, daß jeder Torteil nur von Einrichtungen oberhalb der Toröffnung angetrieben ist, wobei die Laufkatzen Führungsglieder antreiben, die in etwa halber Höhe an den Schienen an den Bahnenden angreifen, und daß jeder Torteil von zwei Bahnen gebildet ist, die im geschlossenen Zustand des Tores parallel zueinander angeordnet sind, und deren Bahnenden mittels der Schiene verbunden sind.The invention achieves the stated object in that each gate part is driven only by means above the gate opening, the trolleys drive guide members which engage the rails at the rail ends at approximately half the height, and in that each gate part is formed by two paths, which are arranged parallel to each other in the closed state of the gate, and their web ends are connected by means of the rail.

Dadurch, daß bei der Erfindung die angetriebenen Führungsglieder in etwa halber Höhe an den Schienen an den Bahnenden angreifen, können große Beschleunigungskräfte auf die Schienen ausgeübt werden, ohne daß die Schienen an den Bahneneden dazu neigen, sich zu verkanten. Es werden sehr rasche Torbewegungen möglich. Die Anordnung zusätzlicher Führungsglieder am Fußboden ist entbehrlich.The fact that in the invention the driven guide members engage at approximately half the height of the rails at the web ends, large acceleration forces can be exerted on the rails without the rails at the web ends tending to tilt. Very rapid door movements are possible. The arrangement of additional guide elements on the floor is unnecessary.

Die Ausbildung jedes Torteils aus zwei Bahnen bringt den weiteren Vorteil mit sich, daß das Tor auch gute Isolationseigenschaften aufweist, weil zwischen den beiden Bahnen ein isolierendes Luftpolster gebildet wird. Dies erlaubt wiederum eine vergleichsweise leichte Bauweise des Tores mit geringer Masse.The formation of each gate part from two webs has the further advantage that the gate also has good insulation properties because an insulating air cushion is formed between the two webs. This in turn allows a comparatively light construction of the gate with a low mass.

Günstig ist es, wenn die Führungsglieder mindestens teilweise zwischen den Bahnen angeordnet sind. Die Bahnen decken dabei die Führungsglieder ab.It is expedient if the guide members are at least partially arranged between the tracks. The tracks cover the guide members.

Ferner werden Seitenabstützungen vorgeschlagen, die sich zwischen der Laufkatze und der Angriffstelle der Führungsglieder an den verbundenen Bahnenden erstrecken. Hierdurch wird eine ausreichende Stabilität der verbundenen Bahnenden sichergestellt.Furthermore, side supports are proposed which extend between the trolley and the point of attack of the guide members at the connected web ends. This ensures sufficient stability of the connected web ends.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. Es zeigen :

  • Fig. 1 eine Ansicht des linken Teils erfindungsgemäßen Tors, wobei Abdeckungen und ähnliche Bauteile zum besseren Verständnis der Erfindung weggelassen sind,
  • Fig. 2 eine vergrößerte Schnittdarstellung durch den oberen Teil des Tores, wobei der linke Torteil gezeigt ist, und
  • Fig. 3 eine Draufsicht mit teilweisem Schnitt auf den oberen Bereich des rechten Torteils, wobei der Maßstab etwa demjenigen der Darstellung der Fig. 2 entspricht.
In the drawing, an embodiment of the invention is shown schematically. Show it :
  • 1 is a view of the left part of the gate according to the invention, wherein covers and similar components are omitted for a better understanding of the invention,
  • Fig. 2 is an enlarged sectional view through the upper part of the gate, the left part of the gate is shown, and
  • Fig. 3 is a plan view with a partial section of the upper area of the right door part, the scale corresponding approximately to that of the representation of FIG. 2.

Das erfindungsgemäße Tor besteht aus zwei Torteilen, die spiegelbildlich zueinander beweglich sind. Die Torteile sind im wesentlichen von den Bahnen 1 und 2 gebildet. Diese Bahnen können beispielsweise Kunststoffolien sein.The door according to the invention consists of two door parts which are movable in mirror image to one another. The gate parts are essentially formed by lanes 1 and 2. These sheets can be plastic films, for example.

Besser ist jedoch, wenn diese Bahnen aus Segeltuch oder einem ähnlichen Material gefertigt sind, wobei auch eine andere Ausgestaltung bzw. eine Kombination verschiedener Materialien möglich ist. Die Bahnen können gänzlich durchsichtig gestaltet sein. Zu empfehlen ist jedoch, wenn die Bahn aus drei Teilen besteht und zwar einem unteren und oberen Teil, die undurchsichtig ist, während in der Mitte ein transparenter Teil eingefügt ist, der sich im Gebrauch etwa in Augenhöhe befindet. Dies ist in der Zeichnung nich näher dargestellt. Eine solche Ausbildung hat den Vorteil, daß die gute Transparenz des Materials auch bei längerem Gebrauch erhalten bleibt und das Material insbesondere der unteren Teile der Bahn der Beanspruchung besser angepaßt werden kann.However, it is better if these webs are made of canvas or a similar material, a different configuration or a combination of different materials also being possible. The tracks can be made completely transparent. However, it is recommended if the web consists of three parts, namely a lower and an upper part, which is opaque, while a transparent part is inserted in the middle, which is in use approximately at eye level. This is not shown in the drawing. Such training has the advantage that the good transparency of the material is retained even after prolonged use and that Material in particular the lower parts of the web can be better adapted to the stress.

Wie sich insbesondere aus der Fig. 3 ergibt, sind die Bahnen 1 und 2 je auf den federgetriebenen Aufwickelwalzen 3 und 4 aufwickelbar, die jeweils von den oberen und unteren Walzenlagern 12 und 13 (siehe auch Fig. 1), getragen sind. Diese Walzenlager 12 und 13 sind im Torrahmen 14 angeordnet, der auch die übrigen Teile des erfindungsgemäßen Tores aufnimmt. Die Walzen 3 und 4 bewegen sich jeweils gegensinnig.As can be seen in particular from FIG. 3, the webs 1 and 2 can each be wound onto the spring-driven winding rollers 3 and 4, which are each supported by the upper and lower roller bearings 12 and 13 (see also FIG. 1). These roller bearings 12 and 13 are arranged in the goal frame 14, which also receives the other parts of the goal according to the invention. Rollers 3 and 4 each move in opposite directions.

Über der Toröffnung 15 erstrecken sich die Träger 16 und 17 und parallel zu den Trägern 16 und 17 sind die Schienen 18 und 19, sowie 20 und 21 angeordnet. Diese Schienen führen je eine Laufkatze 9 für den linken und rechten Torteil, wobei die Schiene 18 der Laufkatze 9 (Fig. 1 und Fig. 2) des linken Torteils zugeordnet ist, während die Schiene 19 der Laufkatze 9 (Fig. 3) des rechten Torteils dient. Die Schienen 20 und 21 dienen dagegen beiden Laufkatzen links und rechts in gleicher Weise.The beams 16 and 17 extend over the gate opening 15 and the rails 18 and 19, and 20 and 21 are arranged parallel to the beams 16 and 17. These rails each carry a trolley 9 for the left and right part of the door, the rail 18 being assigned to the trolley 9 (FIGS. 1 and 2) of the left part of the door, while the rail 19 to the trolley 9 (FIG. 3) of the right Serves part of the gate. The rails 20 and 21, however, serve both trolleys on the left and right in the same way.

Wie sich insbesondere aus den Fig. 2 und 3 ergibt, besitzt jede Laufkatze einen Arm 22, der in seinem vorderen Ende eine Rolle 23 trägt, die je in die Schiene 18 bzw. 19 eingreift.As can be seen in particular from FIGS. 2 and 3, each trolley has an arm 22 which carries in its front end a roller 23 which engages in the rails 18 and 19, respectively.

Die beiden Laufkatzen besitzen ferner je die Rollen 24 bis 27, die an der Schiene 21 geführt sind. Die Schienen 20 und 21 besitzen dabei einen verhältnismäßig großen Abstand voneinander, so daß eine gute Seitenstabilität erhalten wird, von der mittels der Seitenabstützungen 10 auch die Angriffstelle 11 ihre Seitenführung ableitet.The two trolleys also each have the rollers 24 to 27, which are guided on the rail 21. The rails 20 and 21 are at a relatively large distance from one another, so that good lateral stability is obtained, from which the point of attack 11 also derives its lateral guidance by means of the side supports 10.

Wie sich insbesondere aus der Fig. 3 ergibt, sind die Enden 5 der Bahnen 1 und 2 miteinander verbunden und an der U-Schiene 28 befestigt. Diese U-Schiene befindet sich zwischen den Bahnen 1 und 2.3, the ends 5 of the tracks 1 and 2 are connected to one another and fastened to the U-rail 28. This U-rail is located between lanes 1 and 2.

Vor dem Ende 5 der Bahnen ist ein senkrechter Träger 29 angeordnet, der einerseits zur Befestigung des Endes 5 an der U-Schiene 28 dient und der andererseits auch das Profil 30 trägt. Dieses Profil 30 kann beispielsweise eine Einklemmsicherung aufnehmen, wie diese in der DE-OS 30 01 231 beschrieben ist.Arranged in front of the end 5 of the tracks is a vertical support 29 which, on the one hand, serves to fasten the end 5 to the U-rail 28 and, on the other hand, also carries the profile 30. This profile 30 can, for example, accommodate an anti-trap device, as described in DE-OS 30 01 231.

Der Antrieb der beiden Laufkatzen 9 erfolgt über einen nicht näher dargestellten Motor, der die Kette 8 antreibt, die auf den Kettenrädern 31 geführt ist. Die Kette ist bei 32 mit der einen Laufkatze und sinngemäß mit dem anderen Trum mit der anderen Laufkatze verbunden.The two trolleys 9 are driven by a motor, not shown, which drives the chain 8, which is guided on the chain wheels 31. The chain is connected at 32 to one trolley and, analogously, to the other run with the other trolley.

Von der Laufkatze und zwar von dem Arm 22, erstreckt sich jeweils das Führungsglied 6 nach unten und zwar in den Spalt zwischen die Bahnen 1 und 2. Dieses Führungsglied 6 ist an der Angriffstelle 11 gelenkig mit der U-Schiene 28 verbunden, so daß die Antriebskraft etwa in der Mitte der Bahn eingeleitet wird. Die U-Schiene 28 kann dabei, wie Fig. 1 andeutet, in der Mitte ein höheres Profil besitzen, als an den Enden. An der Außenseite der Angriffstelle 11 sind die unteren Enden der Seitenabstützungen 10 befestigt. Durch den Abstand der Walzen 3 und 4 und durch die Gestalt der U-Schiene 28 besitzen die Bahnen 1 und 2 einen Abstand voneinander, so daß sich eine Luftschicht 7 zwischen den Bahnen 1 und 2 befinden wird. Bei der Schließbewegung kann die für die Luftschicht 7 notwendige Luft durch die Öffnungsschlitze 33 nachströmen, wobei davon ausgegangen wird, daß sich der Torrahmen 14 in einem Raum mit relativ höherer Lufttemperatur befindet.From the trolley, namely from the arm 22, the guide member 6 extends downward into the gap between the webs 1 and 2. This guide member 6 is articulated at the point of attack 11 to the U-rail 28, so that the Driving force is introduced approximately in the middle of the track. The U-rail 28 can, as indicated in FIG. 1, have a higher profile in the middle than at the ends. The lower ends of the side supports 10 are fastened to the outside of the point of attack 11. Due to the distance between the rollers 3 and 4 and the shape of the U-rail 28, the webs 1 and 2 are spaced from each other, so that there will be an air layer 7 between the webs 1 and 2. During the closing movement, the air necessary for the air layer 7 can flow in through the opening slots 33, it being assumed that the door frame 14 is located in a room with a relatively higher air temperature.

Es ist klar, daß bei Bedarf an die Luftschlitze 33 auch ein Warmluftkanal anschließbar ist. Die Bleche 34 verbessern den Luftabschluß beim erfindungsgemäßen Tor.It is clear that a warm air duct can also be connected to the air slots 33 if required. The sheets 34 improve the air seal in the gate according to the invention.

Das erfindungsgemäße Tor ist, wie schon erwähnt, vorzugsweise als innerbetriebliches Tor zum Abtrennen der einzelnen Werkhallen od. dgl. gedacht. Es kann auch als Außentor benützt werden, wobei sich jedoch eine Ergänzung durch ein stabiles Tor herkömmlicher Ausbildung empfiehlt.As already mentioned, the gate according to the invention is preferably intended as an internal gate for separating the individual workshops or the like. It can also be used as an external gate, although it is advisable to supplement it with a stable gate of conventional design.

Das erfindungsgemäße Tor ist zu ergänzen durch diejenigen an sich bekannten Bauteile, die das Öffnungssignal und das Schließsignal auslösen. Beim Öffnungsvorgang wird zweckmäßig derart vorgegangen, daß zunächst eine etwa vorhandene Bremse an den Walzen 3 und 4 gelöst wird, so daß die Antriebskräfte der Walzen schon wirksam werden, wenn anschließend der die Kette 8 antreibende Motor eingeschaltet wird. Dadurch wird auch bei hoher Öffnungsgeschwindigkeit eine ausreichende Straffheit der Plane sichergestellt. Der Antriebsmotor kann verschiedene Geschwindigkeitsstufen besitzen, um das Tor möglichst schonend zu bewegen.The gate according to the invention is to be supplemented by those components which are known per se and which trigger the opening signal and the closing signal. When opening, it is expedient to proceed in such a way that an existing brake on the rollers 3 and 4 is first released, so that the driving forces of the rollers are already effective when the motor driving the chain 8 is then switched on. This ensures that the tarpaulin is sufficiently tight even at high opening speeds. The drive motor can have different speed levels in order to move the door as gently as possible.
