Description

Die Erfindung betrifft eine Brandschutzvorrichtung für einen Wanddurchbruch, durch den eine in Segmente aufteilbare Förder- oder Transportanlage zum stetigen Transportieren von Stückgütern hindurchführt, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a fire protection device for a wall breakthrough through which a conveyor or transport system that can be divided into segments for the continuous transport of piece goods passes, according to the preamble of claim 1.

In jüngerer Zeit sind die präventiven Maßnahmen zum Schutz gegen die Feuerausbreitung innerhalb eines Gebäudes für den Brandfall intensiviert worden. Diese Entwicklung wird maßgeblich dadurch gefördert, daß die Brandschutzvorschriften, insbesondere was Brandschutzwände und Brandschutztüren betrifft, in zunehmendem Maße verschärft werden.In recent times, preventive measures to protect against the spread of fire within a building in the event of a fire have been intensified. This development is significantly promoted by the fact that the fire protection regulations, in particular with regard to fire protection walls and fire protection doors, are tightened to an increasing extent.

Das Errichten von funktionsfähigen Brandschutzwänden ist jedoch besonders schwierig, wenn Stückgüter in einem kontinuierlichen Prozeß verarbeitet werden und dementsprechend durch die Brandschutzwand kontinuierlich durchgeführt werden müssen. Aufgrund des stetig fortlaufenden Prozesses muß der Transport der Stückgüter durch einen Wanddurchbruch erfolgen. Solch ein Wanddurchbruch muß aber, wie unmittelbar einleuchtet, im Falle eines Brandes mit einer Brandschutztür verschlossen werden können, damit die Brandschutzwand ihre Funktion erfüllen kann.However, the construction of functional fire protection walls is particularly difficult if piece goods are processed in a continuous process and accordingly have to be carried out continuously through the fire protection wall. Due to the continuous process, the piece goods must be transported through a wall opening. Such a wall breakthrough, however, must be closed with a fire door in the event of a fire, as is immediately evident, so that the fire wall can fulfill its function.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Brandschutzvorrichtung für einen Wanddurchbruch zur Durchführung einer Transportanlage mit einer den Wanddurchbruch im geschlossenen Zustand abdeckenden Brandschutztür zu schaffen, die imstande ist, im Brandfall einen feuersicheren Verschluß des Wanddurchbruchs selbsttätig herzustellen, ohne die Transportbahn zu beschädigen.The invention is therefore based on the object of providing a fire protection device for a wall breakthrough for carrying out a transport system with a fire door covering the wall breakthrough in the closed state, which is capable of automatically producing a fire-proof closure of the wall breakthrough in the event of a fire without damaging the transport path.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Brandschutztür als beim Auslösen einer Arretiervorrichtung selbsttätig schließende Schiebetür ausgebildet ist, und daß die durch den Wanddurchbruch führende Transportbahn zumindest im Bewegungsbereich der Brandschutztür ein beim Lösen eines Arretierungselements selbsttätig aus diesem Bewegungsbereich wegschwenkendes Klappsegment aufweist.This object is achieved in that the fire door is designed as a sliding door that automatically closes when a locking device is triggered, and that the transport path leading through the wall opening has, at least in the movement area of the fire door, a folding segment that swings away automatically from this movement area when a locking element is released.

Die Realisierung der Branschutztür als Schiebetür ist deswegen besonders vorteilhaft, weil eine Schiebetür beim Öffnen und Schließen nur einen sehr kleinen, freizuhaltenden Bewegungsbereich benötigt. Beim erfindungsgemäßen selbsttätigen Schließen der Schiebetür, das beispielsweise federbelastet ablaufen kann, wird gleichzeitig das im Bewegungsbereich der Brandschutztür befindliche Klappsegment der Transportbahn ebenfalls selbsttätig aus dem genannten Bewegungsbereich herausgeschwenkt. Auch dieses Wegschwenken kann beispielsweise federbelastet erfolgen. Sowohl die Brandschutztür als auch das wegschwenkende Klappsegment werden während des Betriebs der Transportbahn durch Arretiervorrichtungen in ihrer Betriebsstellung gehalten. Das Auslösen dieser Arretiervorrichtungen, was das Schließen des Wanddurchbruchs bei gleichzeitigem Wegschwenken des Klappsegments bewirkt, kann beispielsweise von einem Rauchmelder initiiert werden; es ist jedoch auch ohne weiteres möglich, bei einem Produktionsstillstand, beispielsweise abends und am Wochenende, diese Arretiervorrichtungen durch Betätigen eines Schalters auszulösen, um die Brandschutzwand vorsorglich zu schließen.The realization of the branch protection door as a sliding door is particularly advantageous because a sliding door only requires a very small, clear movement area when opening and closing. When the sliding door is automatically closed according to the invention, which can run, for example, spring-loaded, the folding segment of the transport path located in the movement area of the fire protection door is also automatically pivoted out of the movement area mentioned. This pivoting away can also be spring-loaded, for example. Both the fire protection door and the swiveling folding segment are held in their operating position by locking devices during operation of the transport track. The triggering of these locking devices, which causes the wall opening to close while the folding segment swings away, can be initiated, for example, by a smoke detector; However, it is also readily possible to trigger these locking devices by actuating a switch when the production is at a standstill, for example in the evening and at the weekend, in order to preventively close the fire protection wall.

Vorteilhaft vereinfacht wird die Konstruktion des Klappsegments dann, wenn das Klappsegment, um eine zur Transportrichtung etwa senkrechte Achse drehbar, an das vom Wanddurchbruch beabstandete Nachbarsegment der Transportbahn angelenkt ist. Dadurch befindet sich das Klappsegment auf der Seite der Branschutzwand, an der auch die Brandschutztür angebracht ist, und kann deshalb eine minimale Ausdehnung erhalten. Durch die Befestigung des Klappsegments am Nachbarsegment mittels eines Drehgelenks kann das Klappsegment auf einfache Weise aus dem Bewegungsbereich der Brandschutztür weggeschwenkt werden.The construction of the folding segment is advantageously simplified when the folding segment is articulated to the adjacent segment of the transport path, which is spaced from the wall opening, and can be rotated about an axis approximately perpendicular to the transport direction. As a result, the folding segment is located on the side of the fire protection wall on which the fire protection door is also attached and can therefore have a minimal expansion. By fastening the folding segment to the neighboring segment by means of a swivel joint, the folding segment can be pivoted away from the movement area of the fire protection door in a simple manner.

Besonders vorteilhaft ist es, wenn das Klappsegment nach unten wegschwenkbar ausgebildet ist, denn dann kann das Wegschwenken des Klappsegments aus dem Bewegungsbereich der Brandschutztür rein aufgrund der Schwerkraft bewerkstelligt werden, d.h. es sind keinerlei Zusatzkonstruktionen erforderlich, die das selbsttätige Wegschwenken des Klappsegments nach Auslösen des Arretierungselements übernehmen. Nach dieser Ausbildung der Erfindung wird gleichzeitig die Sicherheit im Brandfall erhöht, denn das Klappsegment öffnet stromlos.It is particularly advantageous if the folding segment is designed to be pivotable downwards, because then the pivoting segment can be pivoted away from the movement area of the fire protection door purely on the basis of gravity, i.e. no additional constructions are required which take over the automatic pivoting away of the folding segment after the locking element has been triggered. According to this embodiment of the invention, safety in the event of a fire is increased at the same time, because the folding segment opens without current.

Um ein Nachschwingen des weggeschwenkten Klappsegments; beispielsweise ein Nachpendeln, zu verhindern, kann ein lösbarer Riegel zur Fixierung des weggeschwenkten Klappsegementes an der Klappsegmentaufhängung angebracht sein. Dieser Riegel schließt sich, wenn das Klappsegment in der weggeschwenkten Stellung angekommen ist und verhindert so eine weitere Schwenkbewegung des Klappsegments. Um ein Zurückschwenken des Klappsegments zur Wiederaufnahme des Produktionsprozesses zu ermöglichen, ist der Riegel erfindungsgemäß lösbar ausgebildet.To cause the swinging-away segment to swing away; For example, to prevent a pendulum swing, a releasable bolt for fixing the swung-away folding segment can be attached to the folding segment suspension. This bolt closes when the folding segment has arrived in the pivoted-away position and thus prevents a further pivoting movement of the folding segment. In order to enable the folding segment to be pivoted back to resume the production process, the latch is designed to be detachable according to the invention.

Besondere Vorteile ergeben sich, wenn das Arretierungselement zur Arretierung des Klappsegments als Topfmagnet ausgebildet ist. Solch ein Magnet kann durch Ausfall des erregenden Stromes abgeschaltet werden, wodurch sich die durch den Topfmagneten gebildete Arretierungsvorrichtung löst. Das Abschalten des Topfmagneten kann durch einen Rauchmelder oder durch einen manuellen Schalter erfolgen. Gleichzeitig ergibt sich eine zusätzliche Sicherheit dadurch, daß der Topfmagnet auch dann abgeschaltet wird, wenn das Stromnetz zusammenbricht, ohne daß ein Rauchmelder eine Störung angezeigt hätte.There are particular advantages if the locking element for locking the folding segment is designed as a pot magnet. Such a magnet can be switched off due to a failure of the exciting current, as a result of which the locking device formed by the pot magnet is released. The pot magnet can be switched off by a smoke detector or by a manual switch. At the same time, there is additional security in that the pot magnet is also switched off when the power supply breaks down without a smoke detector having indicated a fault.

Eine andere Ausführung der Erfindung sieht vor, daß eine Rückstellvorrichtung zum automatischen Zurückschwenken des Klappsegmentes in die Transportbahn an das Klappsegment angelenkt ist. Vor allem, wenn das Schließen der Brandschutzwand und damit das Wegschwenken des Klappsegmentes nicht nur in Notfällen vorgenommen wird, sondern bei jeder Produktionsunterbrechung, ist es vorteilhaft, wenn das Klappsegment mittels Knopfdruck automatisch in die Transportstellung zurückgeschwenkt wird.Another embodiment of the invention provides that a reset device for automatically pivoting the folding segment back into the transport path is articulated on the folding segment. Above all, if the fire protection wall is closed and the swinging segment swings away not only in emergencies, but whenever production is interrupted, it is advantageous if the folding segment is automatically swung back into the transport position at the push of a button.

Bevorzugterweise befindet sich die Brandschutztür im geöffneten Zustand über dem Wanddurchbruch, denn auch hier ergibt sich wieder der Vorteil, daß das selbsttätige Schließen der Brandschutztür dann lediglich aufgrund der Schwerkraft erfolgt. Somit entfallen auch hier aufwendige Konstruktionen zum beispielsweise federbelasteten automatischen Schließen.The fire protection door is preferably in the open state above the wall opening, because here too there is the advantage that the fire protection door then closes automatically only due to gravity. This also eliminates the need for complex designs such as spring-loaded automatic closing.

Eine bevorzugte Ausführung der erfindungsgemäßen Brandschutzvorrichtung besteht darin, daß, bezüglich der Transportrichtung, in einem definierten Abstand vor der Brandschutztür und gegebenenfalls vor dem Klappsegment eine Lichtschranke zur Detektierung ankommender Stückgüter angeordnet ist. Solch eine Lichtschranke ermöglicht es, die Transportbahn entweder automatisch zu stoppen, falls die Brandschutztüre geschlossen und das Klappsegment weggeschwenkt sind, oder aber, bei automatischem Betrieb der Brandschutztür und des Klappsegments, die Brandschutztür zu öffnen und das Klappsegment in die Transportbahn zurückzuschwenken, sobald ein Stückgut die Lichtschranke passiert. So ist eine Beschädigung der Stückgüter, auch wenn bei Produktionsbeginn vergessen wurde, die Brandschutztür zu öffnen und das Klappsegment wieder zurückzuschwenken, durch das dann an der erfindungsgemäßen Brandschutzvorrichtung unterbrochene Transportband ausgeschlossen.A preferred embodiment of the fire protection device according to the invention is that, with respect to the direction of transport, a light barrier for detecting incoming piece goods is arranged at a defined distance in front of the fire protection door and possibly in front of the folding segment. Such a light barrier makes it possible to either stop the transport path automatically if the fire protection door is closed and the folding segment is pivoted away, or, if the fire protection door and the folding segment are operated automatically, to open the fire protection door and to swing the folding segment back into the transport path as soon as a piece goods the light barrier passes. Damage to the piece goods, even if it has been forgotten at the start of production to open the fire protection door and to pivot the hinged segment back, is excluded by the conveyor belt then interrupted on the fire protection device according to the invention.

Figur 1 zeigt eine erfindungsgemäße Brandschutzvorrichtung, bei der eine Transportbahn 3 mit Rollen 12 zum stetigen Transportieren von Stückgütern 10 mittels eines Wanddurchbruchs 1 durch eine Brandschutzwand 11 hindurchgeführt ist. Die Brandschutztür 2 ist hier in geöffnetem Zustand dargestellt; sie ist über dem Wanddurchbruch 1 angeordnet, so daß sie, beim Auslösen der sie in der dieser Lage haltenden, nicht dargestellten Arretiervorrichtung, aufgrund der Schwerkraft selbsttätig schließt. Der im Bewegungsbereich der Brandschutztür 2 befindliche Abschnitt der Transportbahn 3 ist als nach unten wegschwenkbares Klappsegment 5 ausgebildet, das in seiner dargestellten, für den Transportprozeß arretierten Lage, durch das Arretierungselement 4 fixiert ist. Das Arretierungselement 4 besteht dabei aus einem Topfmagneten, der an der weiterführenden Transportbahn 3 angebracht ist, und einem am Klappsegment 5 angebrachten Gegenstück 13. Wird nun von einem Rauchmelder ein Brand detektiert, lösen die Arretierungsvorrichtung der Brandschutztüre 2 und das Arretierungselement 4 des Klappsegmentes 5 aus, die Brandschutztür 2 gleitet aufgrund der Schwerkraft vor den Wanddurchbruch 1, das Klappsegment 5 schwenkt, ebenfalls aufgrund der Schwerkraft, um das Drehgelenk 14 im Nachbarsegment 6 aus dem Bewegungsbereich der Brandschutztür 2 nach unten weg, wobei der Riegel 7 einrastet und das Klappsegment 5 gegen ein Zurückschwingen absichert. Die weggeschwenkte Stellung des Klappsegmentes 5 ist hier gestrichelt dargestellt. Sollte die Transportbahn 3 dennoch weiterlaufen, wird sie in dem Moment, in dem ein Stückgut 10 die Lichtschranke 9 passiert, automatisch gestoppt. Damit wird verhindert, daß das Stückgut 10 zwischen dem Nachbarsegment 6 und der dann geschlossenen Brandschutztüre 2 hinunterfällt und beschädigt wird. Die Wiederherstellung der Prozeßstellung des Klappsegmentes 5 und das Öffnen der
Brandschutztüre 2 geschehen in diesem Ausführungsbeispiel von Hand.
FIG. 1 shows a fire protection device according to the invention, in which a transport path 3 with rollers 12 for the continuous transport of piece goods 10 is led through a fire protection wall 11 by means of a wall opening 1. The fire door 2 is shown here in the open state; it is arranged above the wall opening 1, so that it automatically closes due to the force of gravity when the locking device (not shown) holding it in this position is triggered. The section of the transport path 3 located in the movement area of the fire protection door 2 is designed as a folding segment 5 which can be swung downward and is fixed by the locking element 4 in the position shown, which is locked for the transport process. The locking element 4 consists of a pot magnet, which is attached to the further transport path 3, and a counterpart 13 attached to the folding segment 5. If a fire is now detected by a smoke detector, the locking device of the fire protection door 2 and the locking element 4 of the folding segment 5 are triggered , The fire door 2 slides due to gravity in front of the wall opening 1, the folding segment 5 pivots, also due to gravity, around the pivot 14 in the neighboring segment 6 from the movement area of the fire door 2 downwards, the latch 7 engages and the folding segment 5 against a swing back ensures. The pivoted away position of the folding segment 5 is shown here in dashed lines. If the conveyor track 3 continues to run, it is automatically stopped the moment a piece good 10 passes the light barrier 9. This prevents the piece goods 10 from falling between the neighboring segment 6 and the then closed fire protection door 2 and being damaged. The restoration of the process position of the folding segment 5 and the opening of the
Fire protection doors 2 are done by hand in this embodiment.

Figur 2 zeigt ebenfalls eine erfindungsgemäße Brandschutzvorrichtung mit einer Brandschutzwand 11, einer Brandschutztüre 2, einem Wanddurchbruch 1, durch den die Transportbahn 3 mit ihren Rollen 12 führt, sowie ein durch ein Arretierunselement 4 fixiertes Klappsegment 5, das, drehbar am Nachbarsegment 6 befestigt, nach unten weggeschwenkt werden kann. In diesem Ausführungsbeispiel wird das Zurückschwenken des Klappsegmentes 5 in die Produktionsstellung jedoch automatisch durch eine Rückstellvorrichtung 8, das Öffnen der Brandschutztür 2 durch einen nicht dargestellten Rückstellmotor ebenfalls automatisch bewerkstelligt. Diese Rückstellvorrichtungen werden wahlweise durch einen manuell betätigten elektrischen Schalter oder durch ein die Lichtschranke 9 passierendes Stückgut 10 aktiviert. Nach diesem Ausführungsbeispiel ist also ein halbautomatisches oder ein vollautomatisches Öffnen der erfindungsgemäßen Brandschutzvorrichtung bei Produktionsbeginn möglich, was das tägliche öffnen und Schließen des Wanddurchbruchs 1 enorm erleichtert.Figure 2 also shows a fire protection device according to the invention with a fire protection wall 11, a fire protection door 2, a wall opening 1 through which the transport track 3 leads with its rollers 12, and a folding segment 5 fixed by a locking element 4, which, rotatably attached to the neighboring segment 6, follows can be swung away below. In this exemplary embodiment, however, the pivoting back of the folding segment 5 into the production position is automatically accomplished by a reset device 8, and the opening of the fire door 2 by a reset motor (not shown) is also carried out automatically. These reset devices are activated either by a manually operated electrical switch or by a piece goods 10 passing through the light barrier 9. According to this exemplary embodiment, a semi-automatic or fully automatic opening of the fire protection device according to the invention at the start of production is possible, which enormously facilitates the daily opening and closing of the wall opening 1.

Mit der vorliegenden Erfindung ist es also möglich, daß eine Transportanlage zum stetigen Transportieren von Stückgütern durch eine Brandschutzwand hindurchführt, ohne die Funktion der Brandschutzwand im Brandfalle zu beeinträchtigen.With the present invention, it is therefore possible for a transport system for the continuous transport of piece goods to pass through a fire protection wall without impairing the function of the fire protection wall in the event of a fire.

Nach einer weiteren bevorzugten Ausführungsform kann bei der erfindungsgemäßen Brandschutzvorrichtung, bezüglich der Transportrichtung, in einem definierten Abstand vor der Brandschutztür und gegebenenfalls vor dem Klappsegment eine formschlüssige Stoppvorrichtung angeordnet sein.According to a further preferred embodiment, with the fire protection device according to the invention, with respect to the transport direction, a form-fitting stop device can be arranged at a defined distance in front of the fire protection door and possibly in front of the folding segment.

Im Rahmen vorliegender Offenbarung bedeutet der Ausdruck "Topfmagnet" einen "Haftmagneten".In the context of the present disclosure, the term “pot magnet” means a “holding magnet”.
