Abstract

A turning device uses a turning bar for diverting a material web. The turning bar includes a sleeve with a plurality of holes and an inner chamber that is supplied with compressed air, as well as a closing body. The turning bar is supported by a frame and is able to pivot through 90°. The closing body is movable within the inner chamber in response to this pivoting movement of the turning bar. Movement of the closing body closes one of two groups of the holes, depending on the position of the turning bar. The turning bar is connected to the frame at only one end and is supplied with compressed air through a joint connecting the turning bar to the frame.

Description

Beschreibungdescription
Wendevorrichtungturning device
Die Erfindung betrifft einen Wendevorrichtung gemäß dem Oberbegriff der Ansprüche 1 oder 2.The invention relates to a turning device according to the preamble of claims 1 or 2.
Um Materialbahnen, die aus zwei diametral entgegengesetzten Richtungen zugeführt werden, in einer einzigen nachgeordneten Maschine verarbeiten zu können, oder um Papierbahnen, die aus einer gleichen Richtung kommen, zwei verschiedenen Maschinen zur Weiterverarbeitung zuführen zu können, sind Wendestangenapparate entwickelt worden, bei denen die Wendestangen zwischen zwei Arbeitsstellungen bewegbar sind, die jeweils eine Umlenkung der Materialbahn um 90° in entgegengesetzte Richtungen bewirken.In order to be able to process material webs that are fed from two diametrically opposite directions in a single downstream machine, or to be able to feed paper webs that come from the same direction to two different machines for further processing, turning bar apparatuses have been developed in which the turning bars are movable between two working positions, each of which causes the material web to be deflected by 90 ° in opposite directions.
Ein derartiger Wendestangenapparat ist aus DE 43 11 438 C2 bekannt. Er umfasst eine Mehrzahl von Wendestangen, die jeweils an ihren beiden Längsenden gelenkig mit Tragspindeln eines Gestells verbunden und entlang dieser Tragspindeln verschiebbar sind. Die Wendestangen können zwei Arbeitspositionen einnehmen, in denen sie sich jeweils unter einem Winkel von 45° zu den Tragspindeln erstrecken. Durch eine Schwenkbewegung von 90° in der durch die Achsen der Tragspindeln und der Wendestangen definierten Ebene sind die Wendestangen jeweils von einer ihrer zwei Arbeitspositionen in die andere überführbar. Diese Überführung verläuft über eine Zwischenposition, in der die Wendestangen jeweils senkrecht zu den Tragspindeln verlaufen. Um eine solche Überführung zu ermöglichen, müssen die Tragspindeln gekoppelt an die Bewegung der Wendestangen jeweils senkrecht zueinander bewegbar sein.Such a turning bar apparatus is known from DE 43 11 438 C2. It comprises a plurality of turning bars, each of which is articulated at its two longitudinal ends with support spindles of a frame and can be displaced along these support spindles. The turning bars can assume two working positions, in which they each extend at an angle of 45 ° to the support spindles. The turning bars can each be transferred from one of their two working positions to the other by a pivoting movement of 90 ° in the plane defined by the axes of the support spindles and the turning bars. This transfer runs through an intermediate position in which the turning bars are perpendicular to the support spindles. In order to enable such a transfer, the support spindles, coupled to the movement of the turning bars, must be movable perpendicular to each other.
Es sind zwar auch Wendestangenapparate bekannt, bei denen die Wendestangen durch eine 180°-Drehung um eine zur von den Achsen der Tragspindeln und der Wendestangen definierten Ebene parallele Achse von einer Arbeitsstellung in die andere umschaltbar sind. Eine solche Wendestangenanordnung erfordert jedoch oberhalb oder unterhalb dieser Ebene ausreichend Platz, um die Umschaltbewegung durchführen zu können.There are also turning bar apparatuses in which the turning bars are known a 180 ° rotation about an axis parallel to the plane defined by the axes of the support spindles and the turning bars can be switched from one working position to the other. However, such a turning bar arrangement requires sufficient space above or below this level in order to be able to carry out the switching movement.
Die DE 2920684 A1 offenbart ein Linearstellglied zum Verschwenken einer Wendestange.DE 2920684 A1 discloses a linear actuator for pivoting a turning bar.
Die DE 31 27 872 C2 beschreibt eine Wendestange deren erstes Ende gelenkig mit einem Gestell veränderbar und deren zweites Ende verschiebbar in einer Führung gelagert ist. Eine Druckluftzufuhr erfolgt durch ein Gelenk und die Führungen sind mittels Linearantriebe verstellbar sowie mittels Klemmeinrichtungen sicherbar.DE 31 27 872 C2 describes a turning bar whose first end is articulated with a frame and whose second end is slidably mounted in a guide. Compressed air is supplied through a joint and the guides can be adjusted using linear drives and secured using clamping devices.
Der Erfindung liegt die Aufgabe zugrunde, eine Wendevorrichtung mit einer einfach und sicher schwenkbaren Wendestange zu schaffen.The invention has for its object to provide a turning device with a simple and safe pivoting turning bar.
Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 oder 2 gelöst.The object is achieved by the features of claims 1 or 2.
Ein mit der Erfindung erzielbarer Vorteil besteht insbesondere darin, dass sich der mechanische Aufbau der Wendevorrichtung vereinfacht, da eine gelenkige Verbindung des zweiten Längsendes der Wendestange mit dem Gestell entfällt. Es ist daher weder eine zweite Tragspindel noch Mittel zum Steuern von deren Bewegung erforderlich. Die Durchführung der Druckluftzufuhrleitung durch das die Wendestange mit dem Gestell verbindende Gelenk erlaubt einen insbesondere in vertikaler Richtung äußerst kompakten Aufbau; darüber hinaus ist es möglich, auf eine verschleiß- oder verletzungsgefährdete flexible Rohrleitung zum Heranführen der Druckluft an die Wendestange zu verzichten.An advantage that can be achieved with the invention is, in particular, that the mechanical structure of the turning device is simplified, since an articulated connection of the second longitudinal end of the turning bar to the frame is eliminated. There is therefore no need for a second support spindle or means for controlling its movement. The passage of the compressed air supply line through the joint connecting the turning bar to the frame allows an extremely compact construction, particularly in the vertical direction; In addition, it is possible to dispense with a flexible pipe that is prone to wear or injury to bring the compressed air to the turning bar.
Wenn die Wendestange zum Umlenken von Materialbahnen wechselnder Breite eingesetzt wird, ist es wünschenswert, die Ausdehnung des Oberflächenbereichs des Mantels der Wendestange, auf der Blasluft zum Bilden eines Luftkissens unter der umzulenkenden Materialbahn austritt, auf die Breite der Materialbahn begrenzen zu können. Zu diesem Zweck ist vorzugsweise wenigstens ein Kolben, der den druckluftgespeisten Innenraum axial begrenzt, in der Wendestange axial verschiebbar.If the turning bar is used to deflect material webs of varying width, it is desirable to extend the surface area of the To be able to limit the jacket of the turning bar on which blown air emerges to form an air cushion under the material web to be deflected, to the width of the material web. For this purpose, at least one piston, which axially delimits the compressed air-fed interior, is preferably axially displaceable in the turning bar.
Da das freie Ende der Wendestange nicht zum Anschließen der Druckluftzufuhrleitung benötigt wird, kann an diesem freien Ende vorteilhaft ein Stellelement zum Einstellen der Position des wenigstens einen Kolbens aus der Wendestange herausgeführt sein. Dieses Stellelement kann z. B. die Form eines Rändelrades oder einer Kurbel zum Drehen einer Gewindestange haben, die sich in Längsrichtung durch die Wendestange erstreckt und deren Gewinde mit einer Gewindebohrung des Kolbens kämmt.Since the free end of the turning bar is not required for connecting the compressed air supply line, an adjusting element for adjusting the position of the at least one piston can advantageously be led out of the turning bar at this free end. This actuator can, for. B. have the shape of a knurled wheel or a crank for rotating a threaded rod which extends in the longitudinal direction through the turning rod and the thread meshes with a threaded bore of the piston.
Der Schließkörper, der zum selektiven Schließen jeweils einer Gruppe von Löchern des Mantels der Wendestange dient, ist vorzugsweise als Hohlzylinder ausgebildet, wobei der wenigstens eine Kolben innerhalb des Hohlzylinders verschiebbar ist. Diese Anordnung ermöglicht es, den Schließkörper und den wenigstens einen Kolben unabhängig voneinander zu bewegen.The closing body, which serves to selectively close a group of holes in the jacket of the turning bar, is preferably designed as a hollow cylinder, the at least one piston being displaceable within the hollow cylinder. This arrangement makes it possible to move the closing body and the at least one piston independently of one another.
Wenn der wenigstens eine Kolben an dem mit dem Gelenk verbundenen Längsende der Wendestange angeordnet ist, so ist es notwendig, die Druckluft, mit der der Innenraum der Wendestange gespeist wird, durch diesen Kolben hindurch zuzuführen. Zu diesem Zweck ist im Innern der Wendestange ein Abschnitt der Druckluftzufuhrleitung als Rohrabschnitt ausgebildet, der den Kolben durchquert.If the at least one piston is arranged on the longitudinal end of the turning bar connected to the joint, it is necessary to supply the compressed air with which the interior of the turning bar is fed through this piston. For this purpose, a section of the compressed air supply line is formed in the interior of the turning bar as a pipe section, which crosses the piston.
Das Gestell weist zwei Anschläge zum Festlegen der Endpositionen der Schwenkbewegungsfreiheit auf, die vorzugsweise justierbar sind.The frame has two stops for fixing the end positions of the freedom of pivoting movement, which are preferably adjustable.
Ferner ist zweckmäßigerweise wenigstens eine Fixiereinrichtung zum Fixieren der Wendestange in jeweils einer Endposition der Schwenkbewegungsfreiheit vorgesehen. Diese Fixiereinrichtung umfasst zweckmäßigerweise einen mit dem Gestell verbundenen Riegel zum Eingreifen an einem Vorsprung der Wendestange. Einer einfachen Ausgestaltung zufolge ist der Riegel um eine zur Längsachse der Wendestange senkrechte Achse schwenkbar.Furthermore, at least one fixing device is expediently provided for fixing the turning bar in an end position of the freedom of pivoting movement. This fixing device expediently comprises a bolt connected to the frame for engaging on a projection of the turning bar. According to a simple embodiment, the bolt can be pivoted about an axis perpendicular to the longitudinal axis of the turning bar.
Der Schließkörper, der zum selektiven Verschließen jeweils einer Gruppe von Löchern des Mantels vorgesehen ist, ist vorzugsweise um die Längsachse der Wendestange zwischen seinen zwei Stellungen drehbar. Dieses Merkmal erlaubt im Vergleich zu der aus DE 43 11 438 C2 bekannten axialen Verschiebbarkeit des Schließkörpers einen vergrößerten Hub der Bewegung des Schließkörpers, so dass die Anforderungen an die Positionsgenauigkeit der Löcher im Mantel und im Schließkörper relativ niedrig sein können.The closing body, which is provided for the selective closing of a group of holes in the casing, is preferably rotatable about the longitudinal axis of the turning bar between its two positions. This feature allows an increased stroke of the movement of the closing body in comparison with the axial displaceability of the closing body known from DE 43 11 438 C2, so that the requirements for the positional accuracy of the holes in the casing and in the closing body can be relatively low.
Um ein schnelles Umschalten der Wendevorrichtung zwischen den zwei Arbeitspositionen der Wendestange zu ermöglichen, kann ein Linearstellglied, insbesondere ein Pneumatikzylinder, zum Antreiben der Schwenkbewegung vorgesehen werden.In order to enable a quick switching of the turning device between the two working positions of the turning bar, a linear actuator, in particular a pneumatic cylinder, can be provided for driving the pivoting movement.

Die Fig. 1 zeigt die Wendestange 01 in einer „rechten" Arbeitsposition, die zweite, „linke" Arbeitsposition ist durch einen strichpunktierten Umriss angedeutet. Wie insbesondere in dem Schnitt entlang der Linie B - B der Fig. 4 zu erkennen ist, umfasst das Gelenk 26 einen mit dem Längsende der Wendestange 01 fest verbundenen flachzylindrischen Körper 27, der entlang der Schwenkachse in beide Richtungen durch zylindrische Fortsätze 28 mit einem kleineren Durchmesser als dem des Körpers 27 verlängert ist. Diese Fortsätze 28 sind in einer Bohrung des Gleitsteins 23 drehbar gehalten.A turning bar 01 is connected at one longitudinal end via a joint 26 to the sliding block 23 about a vertical axis perpendicular to the plane of FIG. 1 with a freedom of movement of 90 ° between two working positions. 1 shows the turning bar 01 in a "right" working position, the second, "left" working position is indicated by a dash-dotted outline. As can be seen in particular in the section along the line B - B in FIG. 4, the joint 26 comprises a flat cylindrical body 27 which is fixedly connected to the longitudinal end of the turning bar 01 and which has cylindrical extensions 28 with a smaller one in both directions along the pivot axis Diameter than that of the body 27 is extended. These extensions 28 are rotatably held in a bore of the sliding block 23.
Eine Bohrung 29 erstreckt sich in der Ebene der Fig. 1 mittig durch den flachzylindrischen Körper 27. Sie verbindet eine in dem Gleitstein 23 gebildete Kammer 31 mit einem Rohrabschnitt 06, der sich entlang der Längsachse der Wendestange 01 bis etwa in deren Mitte erstreckt.A bore 29 extends in the plane of FIG. 1 centrally through the flat cylindrical Body 27. It connects a chamber 31 formed in the sliding block 23 to a tube section 06 which extends along the longitudinal axis of the turning bar 01 to approximately in the middle thereof.
Der Gleitstein 23 ist ferner mit einem Anschlussstutzen 32 zum Verbinden mit Druckluftleitung versehen, so dass über den Anschlussstutzen 32, die Kammer 31, die Bohrung 29 und den Rohrabschnitt 06 das Innere der Wendestange 01 mit Druckluft beaufschlagbar ist.The sliding block 23 is also provided with a connecting piece 32 for connection to a compressed air line, so that compressed air can be applied to the inside of the turning bar 01 via the connecting piece 32, the chamber 31, the bore 29 and the pipe section 06.
Die Wendestange 01 hat einen zylindrischen Mantel 02, der auf seinem gesamten Umfang und abgesehen von kurzen Stücken an den Längsenden auf seiner gesamten axialen Länge mit gleichmäßig verteilten Löchern 08 versehen ist. Ein Schließkörper 03 in Form eines Hohlzylinders 03 liegt an der Innenwand des Mantels 02 an und ist um die Längsachse der Wendestange 01 drehbar. Wie insbesondere in dem in Fig. 2 dargestellten Schnitt entlang der Line A - A aus Fig. 1 zu sehen ist, ist der Schließkörper 03 jeweils auf eine Hälfte seines Umfangs mit Löchern 04 versehen, die andere Hälfte seines Umfangs ist geschlossen. Die Löcher 04 des Schließkörpers 03 fluchten mit einer ersten Gruppe der Löcher 08 des Mantels 02, die an einer von den Tragspindeln 21 abgewandten Seite des Mantels 02 (in Fig. 2 der nach unten links orientierten Hälfte) liegt. Wenn die Wendestange 01 mit Druckluft beaufschlagt wird, so tritt diese aus dieser ersten Gruppe von Löchern 08 aus und bildet so ein Luftkissen, auf dem ein um 90° umzulenkende Materialbahn, die die Wendestange 01 auf einer Hälfte ihres Umfangs umschlingt, praktisch reibungsfrei geführt werden kann. Die restlichen Löcher 08 des Mantels 02, die auf einem nicht von der Materialbahn umschlungenen Bereich von dessen Umfang (der nach oben rechts orientierten Hälfte in Fig. 2) liegen, sind durch den Schließkörper 03 von der Druckluftzufuhr abgeschnitten.The turning bar 01 has a cylindrical jacket 02 which is provided with uniformly distributed holes 08 over its entire circumference and apart from short pieces at the longitudinal ends over its entire axial length. A closing body 03 in the form of a hollow cylinder 03 bears against the inner wall of the casing 02 and can be rotated about the longitudinal axis of the turning bar 01. As can be seen in particular in the section shown in FIG. 2 along the line AA from FIG. 1, the closing body 03 is provided with holes 04 on one half of its circumference, the other half of its circumference is closed. The holes 04 of the closing body 03 are aligned with a first group of the holes 08 of the casing 02, which is located on a side of the casing 02 facing away from the support spindles 21 (in FIG. 2 the half oriented to the left on the bottom). When the turning bar 01 is pressurized with compressed air, it emerges from this first group of holes 08 and thus forms an air cushion on which a material web to be deflected by 90 °, which wraps around the turning bar 01 on one half of its circumference, is guided practically without friction can. The remaining holes 08 of the jacket 02, which lie on an area of the circumference of which the material web is not wrapped (the half oriented in the upper right in FIG. 2), are cut off from the compressed air supply by the closing body 03.
Beim Verstellen der Wendestange 01 von einer Arbeitsposition in die andere führt der Schließkörper 03 vorzugsweise eine Drehung um 180° aus, so dass die Gruppe von Löchern 04; 08, die in einer Arbeitsstellung der Wendestange 01 offen sind, in der anderen Arbeitsstellung der geschlossenen Hälfte des Umfangs des Schließkörpers 03 gegenüber liegt, während die Löcher 08 der anderen Gruppe dann mit den Löchern 04 des Schließkörpers 03 fluchtet. Eine solche Kopplung der Drehung des Schließkörpers 03 an die Verstellung der Wendestange 01 kann z. B. mit Hilfe eines (nicht dargestellten) ortsfesten Zahnkranzes am Gelenk 26 erfolgen, der mit einer Außenzahnung des Schließkörpers 03 kämmt.When adjusting the turning bar 01 from one working position to the other, the closing body 03 preferably rotates through 180 °, so that the group of Holes 04; 08, which are open in one working position of the turning bar 01, is in the other working position opposite the closed half of the circumference of the closing body 03, while the holes 08 of the other group are then aligned with the holes 04 of the closing body 03. Such coupling of the rotation of the closing body 03 to the adjustment of the turning bar 01 can, for. B. with the help of a (not shown) fixed ring gear on the joint 26 which meshes with an external toothing of the closing body 03.
Eine erste Gewindespindel 07 erstreckt sich von dem in Fig. 3 gezeigten freien Ende der Wendestange 01 her in deren Innerem bis in unmittelbare Nähe des in Fig. 1 gezeigten, mit dem Gelenk 26 verbundenen Endes. Die erste Gewindespindel 07 ist abseits der Längsachse angeordnet und erstreckt sich außerhalb des Rohrabschnitts 06 parallel zu diesem. Ihr Gewinde ist in Eingriff mit einem Innengewinde eines ersten Kolbens 09, der so durch Drehen der ersten Gewindespindel 07 in axialer Richtung der Wendestange 01 verschiebbar ist. Zum Drehen der Gewindespindel 07 ist an ihrem am freien Ende der Wendestange 01 aus dieser herausgeführten Ende ein Stellelement 10, z. B. eine Mutter 10 drehfest angebracht, die z. B. mit Hilfe eines aufgesteckten Schlüssels drehbar ist. Die Seitenflächen des ersten Kolbens 09 liegen dicht an der Innenfläche des hohlzylindrischen Schließkörpers 03 an.A first threaded spindle 07 extends from the free end of the turning bar 01 shown in FIG. 3 in its interior to in the immediate vicinity of the end shown in FIG. 1 connected to the joint 26. The first threaded spindle 07 is arranged off the longitudinal axis and extends outside the pipe section 06 parallel to the latter. Their thread is in engagement with an internal thread of a first piston 09, which is displaceable in the axial direction of the turning rod 01 by rotating the first threaded spindle 07. To turn the threaded spindle 07 is at its free end of the turning rod 01 out of this end an actuator 10, z. B. a nut 10 rotatably attached, the z. B. is rotatable with the help of an attached key. The side surfaces of the first piston 09 lie close to the inner surface of the hollow cylindrical closing body 03.
Ein entsprechender zweiter Kolben 11 , der mit Hilfe einer zweiten, ebenfalls eine Mutter 10 tragenden Gewindespindel 12 axial verschiebbar ist, ist, wie Fig. 3 zeigt, am freien Ende der Wendestange 01 angeordnet. Die zwei Kolben 09; 11 bilden jeweils in axialer Richtung eine Begrenzung des über den Rohrabschnitt 06 mit Druckluft beaufschlagbaren Innenraums 13 der Wendestange 01.A corresponding second piston 11, which is axially displaceable with the aid of a second threaded spindle 12 also carrying a nut 10, is arranged at the free end of the turning bar 01, as shown in FIG. 3. The two pistons 09; 11 each form a limitation in the axial direction of the interior 13 of the turning bar 01 that can be pressurized with compressed air via the pipe section 06.
Die dem Innenraum 13 zugewandten Ränder der Kolben 09; 11 folgen jeweils dem Verlauf einer Kante 14 einer um die Wendestange 01 herumgeschlungenen Materialbahn, d. h. sie haben im wesentlichen den Verlauf von zwei sich jeweils um den halben Kolbenumfang erstreckenden schraubenlinienförmigen Abschnitten von jeweils entgegengesetzter Händigkeit.The edges of the pistons 09; 11 each follow the course of an edge 14 of a material web wound around the turning bar 01, ie they essentially have the course of two each by half Piston-extending helical sections of opposite handedness.
Der Gleitstein 23 trägt zwei unter einem Winkel von 90° zueinander abstehende Arme 16, an deren Ende jeweils ein Anschlag 17 montiert ist, der eine in Fig. 2 gezeigte, der Wendestange 01 zugewandte konkave Seite 18 aufweist. Die beiden Anschläge 17 begrenzen die Schwenkbewegungsfreiheit der Wendestange 01 in dem Gelenk 26 auf exakt 90°. Für eine Feineinstellung der Einstellpositionen bzw. der Schwenkbewegungsfreiheit kann ein Justiermechanismus zum Verstellen der Position des Anschlags 17 parallel zur Richtung der Linie A - A vorgesehen werden.The sliding block 23 carries two arms 16 projecting at an angle of 90 ° to one another, at the ends of which a stop 17 is mounted, which has a concave side 18 shown in FIG. 2 and facing the turning bar 01. The two stops 17 limit the freedom of pivoting of the turning bar 01 in the joint 26 to exactly 90 °. An adjustment mechanism for adjusting the position of the stop 17 parallel to the direction of the line AA can be provided for a fine adjustment of the adjustment positions or the freedom of pivoting movement.
Die Wendestange 01 trägt an zwei gegenüberliegenden Seiten Vorsprünge 33, die jeweils eine dem Mantel 02 der Wendestange 01 zugewandte Schrägfläche 34 aufweisen. Eine in jedem Arm 16 drehbar gelagerte Welle 36 trägt an einem von der Wendestange 01 abgewandten Ende einen Vierkantfortsatz 37, auf den ein entsprechender Schlüssel zum Schwenken der Welle 36 aufsteckbar ist. An ihrem gegenüberliegenden, der Wendestange 01 zugewandten Ende trägt die Welle 36 einen Riegel 38, der an dem linken Arm 16 des Gleitsteins 23 und am rechten Arm 16 jeweils in um 90° gegeneinander verschwenkten Positionen gezeigt ist. Der Riegel 38 des rechten Arms 16 greift hinter die Schrägfläche 34 des Vorsprungs 33 ein und hält so die Wendestange 01 gegen den rechten Anschlag 17 gepresst. Der Riegel 38 weist seinerseits eine Schrägfläche auf, die in dem verriegelten Zustand gegen die Schrägfläche 34 des Vorsprungs 33 drückt. Durch den schrägen Verlauf dieser Schrägflächen 34 wird erreicht, dass wenn durch Schwenken des Riegels 38 aus der am Riegel 38 des linken Arms 16 gezeigten vertikalen Stellung in die horizontale Stellung die Wendestange 01 an dem Anschlag 17 festgelegt wird, der Riegel 38 bereits hinter den Vorsprung 33 eingreifen kann, bevor die Wendestange 01 unmittelbar am Anschlag 17 anliegt, und dass die Verriegelung spielfrei ist.The turning bar 01 has projections 33 on two opposite sides, each of which has an inclined surface 34 facing the jacket 02 of the turning bar 01. A shaft 36 rotatably mounted in each arm 16 carries at one end facing away from the turning bar 01 a square extension 37 onto which a corresponding key for pivoting the shaft 36 can be attached. At its opposite end, facing the turning bar 01, the shaft 36 carries a bolt 38, which is shown on the left arm 16 of the sliding block 23 and on the right arm 16 in each case in positions pivoted by 90 ° with respect to one another. The latch 38 of the right arm 16 engages behind the inclined surface 34 of the projection 33 and thus holds the turning bar 01 pressed against the right stop 17. The latch 38 in turn has an inclined surface which, in the locked state, presses against the inclined surface 34 of the projection 33. The oblique course of these inclined surfaces 34 ensures that when the turning bar 01 is fixed to the stop 17 by pivoting the bolt 38 from the vertical position shown on the bolt 38 of the left arm 16 into the horizontal position, the bolt 38 is already behind the projection 33 can intervene before the turning bar 01 rests directly on the stop 17 and that the locking is free of play.
Fig. 5 zeigt eine Draufsicht auf eine Wendevorrichtung gemäß einer zweiten Ausgestaltung der Erfindung. Die hier vollständig gezeigte Wendestange 01, der Gleitstein 23 sowie die ihn tragenden Tragspindel 21 und Gewindespindel 22 sind die gleichen wie oben mit Bezug auf Fig. 1 bis 4 beschrieben. Der Gleitstein 23 trägt auch jeweils einen linken und einen rechten Anschlag 17 zum Begrenzen der Schwenkbewegungsfreiheit der Wendestange 01. An einem zweiten Arm 39 ist das Gehäuse eines Linearstellglied 41 , z. B. doppelt wirkenden Pneumatikzylinders 41 aufgehängt. Die Aufhängung greift an denjenigen Ende des Zylinders 41 an, an dem auch eine Kolbenstange 42 aus dem Gehäuse austritt. Die Kolbenstange 42 ist wiederum gelenkig mit der Wendestange 01 verbunden. Durch Ein- und Ausfahren der Kolbenstange 42 ist die Wendestange 01 zwischen ihren Arbeitspositionen an einem der zwei Anschläge 17 verstellbar; durch Arretieren der Kolbenstange 42 kann sie in jeweils einer dieser Arbeitsstellungen unbeweglich gehalten werden.Fig. 5 shows a plan view of a turning device according to a second Embodiment of the invention. The turning bar 01 shown completely here, the sliding block 23 and the supporting spindle 21 and threaded spindle 22 carrying it are the same as described above with reference to FIGS. 1 to 4. The sliding block 23 also carries a left and a right stop 17 to limit the freedom of pivoting movement of the turning bar 01. The housing of a linear actuator 41, for. B. double-acting pneumatic cylinder 41 suspended. The suspension acts on that end of the cylinder 41 at which a piston rod 42 also emerges from the housing. The piston rod 42 is in turn articulated to the turning rod 01. By retracting and extending the piston rod 42, the turning bar 01 is adjustable between its working positions on one of the two stops 17; by locking the piston rod 42, it can be held immovably in one of these working positions.
Diese Ausgestaltung ermöglicht ein ferngesteuertes Umschalten der Wendestange 01 zwischen ihren zwei Arbeitspositionen, ohne dass ein direkter Zugang einer Bedienungsperson zu der Wendestange erforderlich ist.This configuration enables the turning bar 01 to be switched remotely between its two working positions without the need for direct access by an operator to the turning bar.
Fig. 6 zeigt einen Ausschnitt einer Wendevorrichtung gemäß einer dritten Ausgestaltung der Erfindung. Wiederum sind die Wendestange 01, deren Vorsprünge 33, das Gelenk 26 und der Gleitstein 23 die gleichen wie mit Bezug auf Fig. 1 bis 4 beschrieben. Es ist lediglich ein Arm 16 in der Fig. 6 dargestellt, ein symmetrisch dazu angeordneter zweiter Arm ist vorhanden. Der Arm 16 trägt zusätzlich zum Anschlag 17 ein Linearstellglied 43, das elektromagnetisch betrieben sein kann oder bei dem es sich wie im Falle der Fig. 5 um einen Pneumatikzylinder 41 handeln kann. Das Linearstellglied 43 trägt parallel zur Längsachse der Wendestange 01 verschiebbar einen Riegel 38. Der Riegel 38 weist zwei Schrägflächen 44; 46 auf, von denen die eine Schrägfläche 44 parallel zur Schrägfläche 34 des Vorsprungs 33 ausgerichtet ist und die andere Schrägfläche 46 sich nahezu senkrecht zur Bewegungsrichtung des Riegels 38 erstreckt. So trifft, wenn die Wendestange 01 in die in der Fig. 6 dargestellte Anschlagposition bewegt wird, der Vorsprung 33 zunächst auf die Schrägfläche 44 und gleitet an dieser entlang, wobei der Riegel 38 entgegen einer von dem Linearstellglied 43 ausgeübten Kraft zurückgedrängt wird. Wenn der Vorsprung 33 die Schrägfläche 44 passiert hat, springt der Riegel 38 wieder vor, und die Schrägflächen 34; 46 kommen in Kontakt miteinander, wodurch die Wendestange 01 in der dargestellten Anschlagposition arretiert wird. Um die Wendestange 01 in die jeweils andere Position zu schwenken, wird das Linearstellglied 43 angesteuert, so dass es den Riegel 38 zurückzieht und die Wendestange 01 freigibt. 6 shows a section of a turning device according to a third embodiment of the invention. Again, the turning bar 01, the projections 33, the joint 26 and the sliding block 23 are the same as described with reference to FIGS. 1 to 4. Only one arm 16 is shown in FIG. 6, there is a second arm arranged symmetrically to it. In addition to the stop 17, the arm 16 carries a linear actuator 43 which can be operated electromagnetically or which, as in the case of FIG. 5, can be a pneumatic cylinder 41. The linear actuator 43 slidably carries a bolt 38 parallel to the longitudinal axis of the turning bar 01. The bolt 38 has two inclined surfaces 44; 46, of which one inclined surface 44 is aligned parallel to the inclined surface 34 of the projection 33 and the other inclined surface 46 extends almost perpendicular to the direction of movement of the bolt 38. Thus, when the turning bar 01 is moved into the stop position shown in FIG. 6, the Projection 33 initially on the inclined surface 44 and slides along it, the bolt 38 being pushed back against a force exerted by the linear actuator 43. When the projection 33 has passed the inclined surface 44, the bolt 38 projects again and the inclined surfaces 34; 46 come into contact with each other, whereby the turning bar 01 is locked in the stop position shown. In order to pivot the turning bar 01 into the respective other position, the linear actuator 43 is actuated so that it pulls back the latch 38 and releases the turning bar 01.
