Description

Pneumatische Bogenabhebevorrichtung mit einer Vielzahl abstellbarer Sauger. Die mit Saugluft arbeitenden Bogenabliebevorrichtungen besitzen bekanntlich Saugstangen, die in angemessenen Abständen in der vollen Breite der Maschine mit Saugköpfen besetzt sind. Mit Rücksicht darauf, daß mit der gleichen Maschine auch Bogen von geringerer Stärke einzeln vom Stapel abzuheben sind, müssen die einzelnen Sauger abstellbar eingerichtet werden, damit durch die beiderseitig vom Bogen befindlichen, also unbeschäftigten. Sauger keine Luft in die Saugleitung gelangt.Pneumatic sheet lifting device with a large number of stops Mammal. It is known that the sheet closing devices operating with suction air have Suction bars that are spaced appropriately across the full width of the machine Suction heads are occupied. With regard to the fact that with the same machine too Lower thickness sheets are to be lifted individually from the stack, the individual The suction cups can be set up so that they can be switched off so that the so unemployed. No air can get into the suction line.

Aus diesem Grunde ist es gegenwärtig üblich, in die Saugkanäle der Sauger einen Hahn zum Freigeben oder `'erschließen des Kanals einzubauen.For this reason, it is currently common practice in the suction channels of the Sucker to build in a tap for releasing or opening up the duct.

Nach der Erfindung erübrigt sich der Einhau dieser Abstellhähne in den Saugern dadurch. daß zum Abstellen des t.uft(lurchlasses vom Sauger nach der Saugstange die Befestigungsschraube verwendet wird, die dazu dient, @lie Sauger oder die Saugergehäuse an der Saugstange dauernd in ausgerichteter Stellung festzuhalten.According to the invention, there is no need to enclose these shut-off taps in the suckers thereby. that to turn off the t.uft (passage from the vacuum cleaner to the Sucker rod the fastening screw is used, which serves to @lie sucker or to hold the suction cup housing permanently in the aligned position on the suction rod.

Hierdurch tritt eine erhebliche Verbilligung der Sauger bzw. der Saugstangen ein, und ferner wird auch deren I?igetigewiclit angemessen vermindert.This results in a considerable reduction in the price of the suction device or the suction rods a, and furthermore their reliability is also appropriately reduced.

Auf der Zeichnung ist die Erfindung beispielsweise an einer Saugstange dargestellt. leren Sauger tangential zur Saugstange und längsverschiebbar in den Saugk#5pfen angeordnet sind.In the drawing, the invention is for example on a suction rod shown. leren suction cup tangential to the suction rod and longitudinally displaceable in the Suction cups are arranged.

Abb. i zeigt ini Längsschnitt den lose auf den Papierstapel aufgesetzten Sauger und Abb.2 die Stellung des Saugers bei tiefer gegen den Papierstapel gesenkter Saugstange.Fig. I shows a longitudinal section of the loosely placed on the stack of paper Suction cup and Fig.2 the position of the suction cup when it is lowered towards the paper stack Suction rod.

Die tangential zur Saugstange a angeordneten, in der Bohrung p des Saugergehäuses b längsverschiebbar gehaltenen Saugköpfe d werden durch Federn f, die sich oben gegen den Gehäusedeckel t stützen, nach abwärts verschoben und in ihrer Bewegung durch Schlitz d' und Stift o begrenzt. Der Führungsschlitz d' befindet sich mit einer Bohrung r in gleicher Ebene, die den Kanal s des Saugkopfes d mibi dem Innern der Saugstange a verbindet.The suction heads d, arranged tangentially to the suction rod a and held longitudinally displaceably in the bore p of the suction housing b , are shifted downwards by springs f, which are supported at the top against the housing cover t, and their movement is limited by slot d 'and pin o. The guide slot d ' is in the same plane with a bore r which connects the channel s of the suction head d to the interior of the suction rod a .

Die das Saugergehäuse b und die Saugstange a durchdringende Befestigungsschraube ic ist gleichachsig zur Bohrung r- angebracht und so lang bemessen, daß sie, die Saugstange a durchquerend, im Bedarfsfalle auf die Bohrung r sich aufsetzen und so, den Luftdurchlaß verschließend, die Stelle des bisher verwendeten Abstellhahnes vertreten kann.The fastening screw penetrating the suction cup housing b and the suction rod a ic is coaxially attached to the r- hole and is so long that it, the Crossing the suction rod a, if necessary, sit on the hole r and so, closing the air passage, the place of the shut-off valve previously used can represent.

Die aus der Zeichnung ersichtliche. Schraubent dient nur dazu, die Saugergehäuse so lange in ausgerichteter Stellung auf der Saugstange a zu sichern, bis sie verbohrt und mit Gewinde zum Eindrehen der eigentlichen Befestigungsschraube tr versehen worden sind.The one evident from the drawing. Screw only serves the purpose To secure the suction cup housing in the aligned position on the suction rod a for so long until it is drilled and threaded to screw in the actual fastening screw tr have been provided.
