Pneumatischer Drehzylinder oder -Teller für einstellbare SchwenkwinkelPneumatic rotary cylinder or plate for adjustable swivel angles
Die Neuerung bezieht sich auf einen pneumatischen Drehzylinder oder -Teller für einstellbare Schwenkwinkel.The innovation refers to a pneumatic rotary cylinder or plate for adjustable swivel angles.
Es sind solche Drehzylinder oder -Teller für diese Zwecke bekannt, bestehend aus einer Zahnstange mit Zahneingriff in einen Zahnkranz am Drehzylinder oder -Teller mit beidseits an der Zahnstange angeordneten Endkolben. Neben Drehzylindern mit Zahnstangenbetätigung gibt es auch solche mit Kniehebel- oder Parallellenkerprinzip. Allen bekannten Lösungen ist gemeinsam, daß die Drehendlagen durch mechanische, teilweise einjustierbare Endanschläge in den Zylinderdeckeln begrenzt werden und eine Endlagenabbremsung durch Druckfedern mit progressiver Kennlinie vorgesehen ist.Such rotary cylinders or plates are known for these purposes, consisting of a rack with tooth engagement in a gear ring on the rotary cylinder or plate with end pistons arranged on both sides of the rack. In addition to rotary cylinders with rack operation, there are also those with a toggle lever or parallel link principle. All known solutions have in common that the rotary end positions are limited by mechanical, partially adjustable end stops in the cylinder covers and end position braking is provided by compression springs with a progressive characteristic curve.
Es ist vorallem Aufgabe der Neuerung, die Bremsfedern zu vermeiden und durch andere austausch- und einstellbare Aggregate zu ersetzen, um einen vielseitigen Einsatz mit einerThe main purpose of the innovation is to avoid the brake springs and replace them with other interchangeable and adjustable units in order to enable versatile use with a
Vorrichtung bei definierter Mittelstellung zu erreichen.Device to be reached at a defined center position.
Zur Lösung dieser Aufgabe kennzeichnet sich der pneumatische Drehzylinder oder -Teller für einstellbare Schwenkwinkel nach dem Oberbegriff von Anspruch 1 dadurch, daß der Anschlag der Endkolben jeweils von einem pneumatisch verstellbaren Tändemkolben zur Einstellung des Schwenkwinkels mit Bewegungsdrosselung begrenzbar ist. Hierbei können die Führungshülsen der Tandemkolben als Schraubenhülsen jeweils den verstellbaren Endanschlag bilden. Die beiden Tandemkolben sind zur Erreichung der Mittelstellung der Zahnstange mit Endkolben in volle Ausfahrstellung zu bringen.To solve this problem, the pneumatic rotary cylinder or plate for adjustable swivel angles according to the preamble of claim 1 is characterized in that the stop of the end pistons can be limited by a pneumatically adjustable tandem piston for adjusting the swivel angle with movement throttling. Here, the guide sleeves of the tandem pistons can each form the adjustable end stop as screw sleeves. The two tandem pistons must be brought into the fully extended position to achieve the center position of the rack with end piston.
In der Zeichnung sind beispielsweise bevorzugte Ausführungsformen von pneumatischen Drehzylindern oder -Teller gemäß der Neuerung dargestellt und nachfolgend beschrieben und zwar zeigen:In the drawing, for example, preferred embodiments of pneumatic rotary cylinders or plates according to the innovation are shown and described below, namely:
Figur 1 und 2 den Längsschnitt einer ersten Ausführung eines pneumatischen Drehzylinders in MitFigures 1 and 2 show the longitudinal section of a first embodiment of a pneumatic rotary cylinder in Mit

Figur 3 und 4 den Längs- und Mittelschnitt einer zweiten Ausführung eines pneumatischen Drehzylinders in Mittelstellung undFigures 3 and 4 show the longitudinal and central section of a second embodiment of a pneumatic rotary cylinder in the middle position and
Figur 5 bis 7 verschiedene Steuereinstellungen für denFigure 5 to 7 different control settings for the
pneumatischen Drehzylinder der Neuerung.pneumatic rotary cylinder of the innovation.
Wie aus der Zeichnung nach Figur 1 und 2 bei der ersten Ausführung ersichtlich wird, ist der pneumatische DrehzylinderAs can be seen from the drawing in Figures 1 and 2 in the first version, the pneumatic rotary cylinder
1 mit einem ggfs. aufgesetzten - hier nicht dargestellten Drehteller durch Zahneingriff an der Zahnstange 2 mit seinem Zahnkranz 3 im Schwenkwinkel verstellbar. Die Zahnstange1 with a possibly attached turntable (not shown here) adjustable in the swivel angle by meshing with the toothed rack 2 with its toothed ring 3. The rack
2 weist beidseits pneumatische Kolben 4 und 5 auf, welche durch Radialbohrungen 6 und 7 im Pneumatikzylinder 8 mit Druckluft beaufschlagbar sind und damit die Zahnstange 2 in Linearbewegung versetzbar ist, welche sodann, wie vorgeschildert, in Drehbeweung umgesetzt wird. Hier sind den Kolben 4 und 5 je ein Tandemkolben 9 und 10 zur genau definierten Haltestellung nachgeschaltet, welche auch eine genau definierte Mittelstellung des Pneumatikkolbens 3 und damit eine genaue Ausgangsstellung für die Schwenkbewegung des Drehzylinders 1 ermöglichen. Die Tandemkolben 9 und 10 sind über Axialbohrungen 11 und 12 pneumatisch beaufschlagbar und weisen einerseits Führungs- und Dichtungsbuchsen 13 und 14 auf mit Endabdeckung 15 und 16 andererseits.2 has pneumatic pistons 4 and 5 on both sides, which can be pressurized with compressed air through radial bores 6 and 7 in the pneumatic cylinder 8 and thus the rack 2 can be set in linear motion, which is then, as described above, converted into rotary motion. Here, the pistons 4 and 5 are each followed by a tandem piston 9 and 10 for the precisely defined holding position, which also enable a precisely defined center position of the pneumatic piston 3 and thus a precise starting position for the swivel movement of the rotary cylinder 1. The tandem pistons 9 and 10 can be pneumatically pressurized via axial bores 11 and 12 and have guide and sealing bushings 13 and 14 on the one hand with end covers 15 and 16 on the other.
In Figur 3 und 4 der Zeichnung wird eine zweite Ausführung ersichtlich. Hier ist wiederum ein pneumatischer Drehzylinder 21 ggfs. mit aufgesetztem Drehteller 21a ersichtlich, welcher durch Zahneingriff der Zahnstange 22 mit seinem Zahnkranz 23 im Schwenkwinkel verstellbar ist. Die Zahnstange 22 weist beidseits wiederum pneumatische Kolben 24 und 25 auf mit pneumatischer Beaufschlagung über die Radialbohrungen 26 und 27 im Pneumatikzylinder 28, welcher die Zahnstange 22 in Linearbewegung versetzt, welche sodann, wie vorgeschildert, in Drehbewegung umgesetzt wird. Auch hierA second version is visible in Figures 3 and 4 of the drawing. Here again a pneumatic rotary cylinder 21, possibly with a rotary plate 21a attached, can be seen, which can be adjusted in the swivel angle by the meshing of the rack 22 with its ring gear 23. The rack 22 has pneumatic pistons 24 and 25 on both sides with pneumatic pressure via the radial bores 26 and 27 in the pneumatic cylinder 28, which sets the rack 22 in linear motion, which is then converted into rotary motion as described above. Here too
ist den Kolben 24 und 25 je ein Tandemkolben 29 und 30 zur genau definierten Mittel- bzw. Haltestellung nachgeschaltet. Die Tandemkolben 29 und 30 werden wiederum über Axialbohrungen 31 und 32 pneumatisch beaufschlagt, wobei die Dichtungs- und Führungsbuchsen 33 und 34, welche durch Schraubverstellung einstellbar sind und als Endanschläge für die Pneumatikkolben 24 und 25 dienen, wofür die Endabdeckungen 35 und 36 abzunehmen sind.A tandem piston 29 and 30 is connected downstream of the pistons 24 and 25 to the precisely defined middle or holding position. The tandem pistons 29 and 30 are in turn pneumatically actuated via axial bores 31 and 32, whereby the sealing and guide bushings 33 and 34, which can be adjusted by screw adjustment and serve as end stops for the pneumatic pistons 24 and 25, for which the end covers 35 and 36 must be removed.
Schließlich sind in den Figuren 5 bis 7 noch verschiedene Steuereinstellungen für die pneumatische Drehregelung dargestellt und zwar zeigen Figur 5 das Anfahren der Endlage mit Regelung über Drosselventile; Figur 6 das Anfahren der Endlage und Mittelstellung sowie Figur 7 das Anfahren von Endlage, Mittelstellung und Warteposition.Finally, Figures 5 to 7 show various control settings for the pneumatic rotary control. Figure 5 shows the approach to the end position with control via throttle valves; Figure 6 shows the approach to the end position and middle position, and Figure 7 shows the approach to the end position, middle position and waiting position.
