Description
Schaufelrad zum Ausführen gefalzter Bogen Am Bogenausgang von Rotationsdruckmaschinen werden die im Falzapparat gefalzten Bogen den Schaufeln eines Schaufelrades zugeführt, welche sie auf ein Transportband ablegen. Die bisher bekannten Schaufeln sind aus Flachstahl gefertigt und auf sternförmigen Scheiben befestigt, von denen mehrere nebeneinander auf einer gemeinsamen Achse angeordnet sind. Schwere gefalzte Bogenpacks mit hoher Seitenzahl schießen mit besonders großer Wucht in die Schaufelzwischenräume und schmieren insbesondere an den Kanten der mit geringerer Geschwindigkeit umlaufenden Schaufeln ab. Bisherige Bemühungen, durch besondere Formgebung und große abgerundete Kanten sowie durch Polieren und Verchromen der Schaufeln Beschädigungen und Verschmieren des frischen Druckes zu verhindern, haben nicht befriedigt.Paddle wheel for carrying out folded sheets At the sheet exit of rotary printing presses the sheets folded in the folder are fed to the blades of a paddle wheel, which they place on a conveyor belt. The previously known blades are out Made of flat steel and mounted on star-shaped disks, several of which are arranged side by side on a common axis. Heavy folded sheet packs with a large number of sides shoot with particularly great force into the spaces between the blades and lubricate especially on the edges of those rotating at a lower speed Shovel off. Efforts so far, through special shaping and large rounded Edges as well as damage and smearing from polishing and chrome-plating the blades of fresh printing did not satisfy.
Der Erfindung liegt die Aufgabe zugrunde, diese Mängel zu beheben. Das gelingt gemäß der Erfindung dadurch, daß die einzelnen Schaufeln längsseits beiderseitig von Rollen flankiert sind, die über die Schaufeloberfläche vorragen. Dabei kommt der einschießende Bogenpack nicht mehr auf der Schaufeloberfläche zum Gleiten, sondern wird von den Rollen getragen. Da die Rollen sich mitdrehen, findet keine Beschädigung des Druckes und kein Abschmieren mehr statt. Besonders wenn die Rollen an ihrem äußeren Umfang einen Gummiüberzug aufweisen, drehen sie sich sofort mit dem einschießenden Bogenpack mit, was weiter dadurch gefördert werden kann, daß die Rollen auf Wälzlagern laufen bzw. von den Außenringen von Kugellagern selbst gebildet werden. The object of the invention is to remedy these deficiencies. This is achieved according to the invention in that the individual blades are alongside Are flanked on both sides by rollers that protrude above the blade surface. In doing so, the sheet pack that is shooting in no longer comes to the surface of the shovel Glide, but is borne by the rollers. Since the roles turn with it, finds no more damage to the print and no more smearing. Especially when the If rollers have a rubber coating on their outer circumference, they rotate immediately with the incoming sheet pack, which can be further promoted by it, that the rollers run on roller bearings or from the outer rings of ball bearings themselves are formed.
Damit sich die Bogenpackexemplare bei der gekrümmten Form der Schaufeln an den einzelnen Rollen nicht stoßen und damit schief zur Auslage kommen, sieht die Erfindung ferner vor, daß die Rollen auf der einen Seite der Schaufel gegenüber denen auf der anderen Seite versetzt angeordnet sind Um bei federharten Schaufeln, die verwendet werden, wenn sie sich bei einer Störung in der Maschine nicht verbiegen sollen, Rollen leicht anbringen zu können, sind sie auf besonderen Haltern angeordnet, die auf die Schaufeln gesteckt und mit ihnen fest verbunden, insbesondere verklemmt werden.So that the arch pack copies with the curved shape of the blades not bump into the individual rolls and thus come to the display at an angle The invention also proposes that the rollers are on one side opposite the bucket which are offset on the other side. which are used if they do not bend in the event of a malfunction in the machine should be able to attach roles easily, they are arranged on special holders, which are placed on the blades and firmly connected to them, in particular jammed will.
Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung schematisch dargestellt. Es zeigt F i g. 1 die Seitenansicht eines Schaufelrades, F i g. 2 einen Querschnitt durch eine Schaufel, F i g. 3 einen Querschnitt durch eine federharte Schaufel mit besonderem Rollenhalter. Two embodiments of the invention are shown schematically in the drawing shown. It shows F i g. 1 shows the side view of a paddle wheel, FIG. 2 one Cross section through a shovel, FIG. 3 shows a cross section through a spring-loaded one Scoop with a special roll holder.
Auf dem Schaufelradkörperl sind ringsum mehrere Schaufeln 2 mittels Schrauben 3 befestigt. Diese Teile sind schmal; von ihnen sind mehrere mit Abstand nebeneinander - in der Zeichnungsebene der F i g. 1 also hintereinander - auf einer gemeinsamen Achse befestigt und bilden in ihrer Gesamtheit das Schaufelrad. On the impeller body, several blades 2 are all around Screws 3 fastened. These parts are narrow; of them are several by a distance side by side - in the plane of the drawing of FIG. 1 in a row - on one attached common axis and form in their entirety the paddle wheel.
Zu beiden Seiten der Schaufeln 2 sind nun gemäß der Erfindung Rollen 4 gegeneinander versetzt angeordnet. Die Rollen 4 bestehen jeweils aus zwei Kugellagern 5 und werden auf Bolzen 6 geführt, die in einer Bohrung 7 in der Schaufel 2 eingepreßt und durch einen Stift 8 gesichert sind. Der äußere Umfang der Kugellager ist mit einem Gummiüberzug 9 versehen, z. B. in Form eines gespannten Gummiringes. According to the invention, rollers are now on both sides of the blades 2 4 arranged offset from one another. The rollers 4 each consist of two ball bearings 5 and are guided on bolts 6 which are pressed into a bore 7 in the blade 2 and are secured by a pin 8. The outer circumference of the ball bearing is with a rubber cover 9 is provided, e.g. B. in the form of a stretched rubber ring.
Auf die federharten Schaufeln 2 der F i g. 3 sind besondere Halter 11, welche die Rollen 4 auf Gewindebolzen 10 tragen, aufgesteckt und durch Schrauben 12 mit ihnen fest verklemmt. On the spring-hard blades 2 of FIG. 3 are special holders 11, which carry the rollers 4 on threaded bolts 10, attached and screwed 12 firmly jammed with them.
