P.A.663 977*22.11.67P.A. 663 977 * 11/22/67
Die Erfindung betrifft eine Vorrichtung , um in einfacher und betriebssicherer Weise einzelne pneumatische, logische Elemente untereinander zu verbinden.The invention relates to a device in order in a simple and reliable manner to connect individual pneumatic, logical elements with each other.
Es ist bekennt, pneumatische, logische Elemente des dynamischen und statischen Typs In geschlossenen Bausteinen darzustellen, so daß in dem einzelnen Element mehrere Funktionen wie UND-, ODER-, NEGATIONS-, IDENTITÄTS-, SPEICHER-und FLIP-FLCP-Glieder enthalten sind. Der vorliegenden Steueraufgaben entsprechend werden diese Elemente untereinander verbunden. In den Verbindungsleitungen herrschen je noch dem Betriebszustand Drücke von einigen hundert Millimeter Wassersäule bis zu einigen ctü. Insbesondere sind statische Elemente bekannt geworden, die mit Betriebs- f.jIt is known to be pneumatic, logical elements of dynamic and static types To be shown in closed modules, so that several Functions like AND, OR, NEGATION, IDENTITY, MEMORY and FLIP FLCP elements are included. These elements are connected to one another in accordance with the control tasks at hand. In the connecting lines ever prevail nor the operating state pressures of a few hundred millimeters of water column up to some ctü. In particular, static elements have become known that are associated with operational f.j

den Ausgängen der logischen Elemente beaufschlagt werden können. Pneumatische, logische Elemente und Schaltungen werden insbesondere dort verwendet, wo es auf houe Befrleosslcherheit ankommt bzw. In einer Umgebung, welche den Einsatz elektronischer, logischer Bausteine verbietet. Es handelt sich dabei beispielsweise um explosionsgefährliche Verhältnisse, staubige, schmutzige, feuchte oder säurehaltige Atmosphäre und dergi . mehr. Nach dem heutigen Stand der Technik gelten-pneumafisch arbeitende logische Steuerungen als betriebssicherer, wenn die Verbindung der einzelnen Elemente untereinander zuverlässig ausgeführt wird.the outputs of the logical elements can be acted upon. Pneumatic, logic elements and circuits are used particularly where it depends on ho u e Befrleosslcherheit or in an environment that prohibits the use of electronic, logical building blocks. These are, for example, explosive conditions, dusty, dirty, humid or acidic atmospheres and other things. more. According to the current state of the art, pneumatic logic controls are considered to be more reliable if the connection between the individual elements is carried out reliably.
In einfachen Fällen und bei niedrigen Ansprüchen werden die Verbindungen durch elastische Kunststoffschlcuche hergestellt. Diese Verbindungsart hat den Vorzug, daß sie Veränderungen erlaubt, bis die oftmals komplizierten Steuerungen einwandfrei funktionieren. Die Schläucue können abgezogen und In anderen Verbindungen wieder aufgesteckt werden. Der Nachteil dieser Verbindungsart besteht jedoch darin, dcß bei längerer Betriebszeif die Kunststoffschläuche altern, wodurch sie in ihrer Spannung auf den Schlauchtüllen soweit nachlassen, dcß sie oei Druckstößen sich lösen können. Insbesondere bei hohen Drücken gilt diese Verbindungsart als unzuverlässig.In simple cases and with low demands, the connections are made using elastic plastic hoses. This type of connection has the advantage that it allows changes until the often complex controls function properly. The Schläuc u e can be removed and reattached to other compounds. The disadvantage of this type of connection, however, is that the plastic hoses age during prolonged operation, so that their tension on the hose nozzles slackens to such an extent that they can loosen in the event of pressure surges. This type of connection is considered to be unreliable, especially at high pressures.
Es wurae c^ch bereits vorgeschlagen, die einzelnen logischen Elemente auf Grundplatten cufzubcjen, In denen Bohrungen soweit vorgearbeitet sind, daß sie, nachdem die Planung festliegr, vollends durchgebohrt und untereinander verbunden werden können. Der Grundblock weist dan-if ein System von Bohrungen auf, die sich in verschiedenen Richtungen und Ebenen kreuzen. Die elnzeinen Blöcke werden untereinander durch spezielle Dichtungen aus elastischem Werkstoff verbunden. Der Nachteil dieser an sich betriebssicheren Verbinaungsart Ist darin zu erblicken, daß die Schaltung vorher genau festgelegt sein muß, we·! nachträgliche Änderungen unmöglich sind. Ferner ist die Herstellung der Grundstöcke relativ teuer. Das Durchbohren oder Durchstoßen der Trennwände zwischen den einzelnen Bo'-rungen Ist eine heikle und schwierige Arbeit, die Sorgfalt erfordert·. Eine falsch durchbohrte Trennwand macht den Grundstein unbrauchbar. Es kommt hinzu, daß die Luftkanäle bei dieser Insta!lationscrt sehr winkelig und um mehrere Ecken geführt sind, wodurch sich die Strö-upgswiderstände erheblich erhöhen. Die Schaltzeiten der an sich rasch arbeitenden logischer. Elemente werden durch solche komplizierten Kanalsysteme stark herabgesetzt.It has already been proposed to cufzubcjen the individual logical elements on base plates, in which the holes are prepared so that they can be completely drilled through and connected to each other after the planning is fixed. The basic block has a system of holes that intersect in different directions and levels. The individual blocks are connected to one another by special seals made of elastic material. The disadvantage of this type of connection, which is reliable in itself, can be seen in the fact that the circuit must be precisely defined beforehand, because! subsequent changes are impossible. In addition, the foundations are relatively expensive to manufacture. Drilling or piercing the partition walls between the individual holes is a delicate and difficult job that requires care. A wrongly drilled partition renders the foundation stone unusable. There is also the fact that the air ducts in this installation are very angled and led around several corners, as a result of which the flow resistances increase considerably. The switching times of the inherently fast working more logical. Elements are greatly degraded by such complicated sewer systems.

Der Gedanke der Erfindung ist in Figur 1 im Längsschnitt, in Figur 2 Im Querschnitt dargestellt. Ein rahmenförmiges Gehäuse 1 enthält die in vorteilhafter V/eise aus Kunststoff hergestellte Montageplatte 2, welche mit mehreren Schrauben 3 befestigt ist. Das Gehäuse 1 kann seinerseits mit Befestigungsschrauben 4 on einer Konsole, einer Maschine oder dergl. festgeschraubt werden. Die logischen Elemente 5 sind in nicht näher dargestellter Weise durch Schrauben, Klemmbügel oder dergl. gegen die Montageplatte 2 gepreßt, wobei elastische Dichtungen 6 für die druckdichte Verbindung sorgen. Die Elemente befinden sich unter einer vorzugsweise aus transparentem Kunststoff hergestellten und aufgeschraubten Haube 7, die Bohrungen 8 aufweist, durch welche die den Elementen entströmende Luft ins Freie entweichen kann. Eine Filterplatte 9 dient als Schalldämpfer. Bei dem Einbau dynamischer Elemente sorgt die poröse Filterplatte 9 zusätzlich dafür, daß kein Staub in das Gehäuse gelangen kann.The concept of the invention is shown in Figure 1 in longitudinal section, in Figure 2 in cross section shown. A frame-shaped housing 1 contains the advantageously made of plastic produced mounting plate 2, which is fastened with several screws 3. That Housing 1 can in turn with fastening screws 4 on a console, a machine or the like. The logic elements 5 are not shown in detail in FIG Way by screws, clamps or the like. Pressed against the mounting plate 2, elastic seals 6 ensure the pressure-tight connection. The Elements are located under a preferably made of transparent plastic and screwed on Hood 7, which has bores 8 through which the air flowing out of the elements can escape into the open. A filter plate 9 serves as a silencer. When installing dynamic elements, the porous filter plate 9 also ensures that no dust can get into the housing.
In die Montageplatte 2 sind entweder Schlauchnippel eingefügt oder die Platte ist an den entsprechenden Anschlußstellen mit leicht konischen Bohrungen 11 versenen, in welche elastische Schläuche eingeführt und durch Pressung befestigt werden können.In the mounting plate 2 either hose nipples are inserted or the plate is to the corresponding connection points with slightly conical bores 11 versenen into which elastic hoses can be inserted and fixed by pressing.
Bei Steuerungsaufgaben, deren Lösung nicht vollständig klar ist, wird man Montageplatten mit soviel eingepreßten Schlauchnippeln 10 bevorzugen, daß alle evtl. möglichen Schaltpläne realisiert werden können. Eine derart verschlauchte Schaltung kann erprobt, ergänzt und erweitert werden. Es ist auch möglich, in die Verbindungssdhläuche Drosseln, T-Stücke und dergl. einzufügen, damit die Schalt- und Steuerungsaufgabe optimal erfüllt wird.For control tasks, the solution of which is not completely clear, one becomes mounting plates with so many hose nipples 10 pressed in that all possible circuit diagrams can be realized. Such a tubed circuit can be tested and supplemented and be expanded. It is also possible to use throttles and T-pieces in the connecting hoses and the like. To be inserted so that the switching and control task is optimally fulfilled.
!st eine dergestalt verschlauchte Schaltung erprobt und sicher, so kann der Raum unter der Montageplatte 2 mit einem kalthärtenden Gießharz 12 oder einer anderen geeigneten Vergußmasse ausgefüllt werden, so daß die Verbindungen einwandfrei und betriebssicher festgelegt und gedichtet sind. Liegt die Schaltung endgültig fest, so daß Serienlieferungen einsetzen, so können die Schlauchnippel 10 eingespart werden. Die Verbindungsschläuche werden in diesem Fell in die konischen Bohrungen 11 eingeschoben, die Montageplatte 2 kann fertig verschlaucht geprüft und dann wie vorbeschrieben vergossen were ι.! If such a hose circuit has been tested and is safe, the space under the Mounting plate 2 with a cold-curing casting resin 12 or another suitable one Sealing compound are filled so that the connections are flawless and reliable are fixed and sealed. If the circuit is finally set, so that series deliveries use, so the hose nipple 10 can be saved. The connecting hoses are inserted in this skin into the conical bores 11, the mounting plate 2 can be finished hoses checked and then potted as described above.
In einer oder mehreren Positionen der Montageplatte 2 können oben Anschlußplatten 13 aufgeschraubt werden, welche ihrerseits Schlauchnippel 10 tragen. Dort werden die Lei-Ijngen für ein- oder abgehende Signale angeschlossen und durch Durchbrüche der Haube 7 nach außen geführt.In one or more positions of the mounting plate 2, connecting plates 13 are screwed on, which in turn carry hose nipples 10. This is where the lei boys are for incoming or outgoing signals and through openings in the cover 7 outwards.
V/erden mehrere Schaltblöcke benötigt, so kann eine Reihe der rahmenförmigen Gehäuse 1 nebeneinander gestellt und seitlich verschraubt werden. Die Verbindungsschläuche 15If several circuit blocks are required, a number of the frame-shaped housings 1 placed side by side and screwed on the side. The connecting hoses 15

Die gesamte Biockformation kann anschließend in der vorbeschriebenen Weise fixiert werden. An den notwendigen Stellen sind Anschlußplatten 13 eingefügt, damit die Signalleitungen anschließbar sind.The entire block formation can then be fixed in the manner described above will. Connection plates 13 are inserted at the necessary points so that the Signal lines can be connected.
Bei dem Verschlauchen mit nachfolgendem Vergießen lassen sich, insbesondere denn, wenn kalthörtende Vergußmassen verwendet werden, Schlauche aus billigen thermoplastischen Kunststoffen verwenden. Es ist ferner möglich, wenn die Schlauche entsprechend temperarurbesfändsg gewöhn werden, die Montageplatte 2 samt der ganzen Verschlauchung imit duroplastischen Massen, beispielsweise nach dem transfer molding Verfahren zu einem kompakten Körper zu umpressen.In the case of tubing with subsequent potting, it is possible, in particular, if cold-curing potting compounds are used, cheap thermoplastic tubing is used Use plastics. It is also possible if the hoses are made accordingly temperarurbesfändsg be used to the mounting plate 2 together with the whole Tubing with thermoset compounds, for example after transfer molding Overmolding process to form a compact body.
Damit die Vergußmasse nicht auf die Montageflöche für die Elemente gelangt, ist es vorteilhaft, wenn die Bohrungen 8 in der Montageplatte 2 nicht durchgängig gepreßt sind, sondern on Stellen durchstoßen werden, wo Anschlußschläuche notwendig sind.So that the potting compound does not get onto the mounting surface for the elements, it is advantageous if the bores 8 in the mounting plate 2 are not pressed continuously are, but are pierced on places where connection hoses are necessary.
