Description

Bogenausleger für bogenverarbeitende Maschinen, bei der zwischen zwei umlaufenden Ketten Greiferstangen befestigt sind Um bei Kettenauslegern den Bogen nicht mit voller Geschwindigkeit gegen den Papieranschlag stoßen zu lassen, sind folgende Verzögerungsmöglichkeiten bekannt: 1. Die Geschwindigkeit der Kette verzögert sich im Moment der Bogenablage.Sheet delivery for sheet processing machines, where between two Circumferential chains gripper bars are attached to the bow with chain booms do not hit the paper stop at full speed the following delay options are known: 1. The speed of the chain is delayed at the moment of depositing the sheet.

2. Der Bogen wird mittels Saugluft zurückgehalten. 2. The sheet is held back by means of suction air.

3. Der Bogen wird vom Kettengreifer an Saugschnäbel übergeben, die ihn verlangsamen und zur Ablage bringen. 3. The bow is transferred from the chain gripper to suction beaks, which slow it down and bring it to the shelf.

4. Der Bogen wird mittels besonders angeordneter Kettengreifer über Kettenräder umgelenkt, wobei die Greiferauflage Drehpunkt ist (deutsche Patentschrift 276 493). 4. The sheet is pulled over by means of a specially arranged chain gripper Sprockets deflected, with the gripper support being the fulcrum (German patent specification 276 493).

Bei der hier beschriebenen Auslage werden die Ketten ebenfalls über Kettenräder 1 umgelenkt, die Greiferauflage macht jedoch diese Drehbewegung nicht mit. Die Greiferstange wird vielmehr durch eine in der Zeichnung nicht dargestellte Kurve in ihrer Lage gehalten, so daß sich nur das Kettenglied und die daran befestigte Greiferstangenlagerung verdreht, während die Greiferauflage zusammen mit dem Bogen eine Gerade bildet. In the case of the display described here, the chains are also over Sprockets 1 deflected, but the gripper support does not make this rotary movement with. The gripper bar is rather by a not shown in the drawing Curve held in place so that only the chain link and the attached to it Gripper rod storage twisted, while the gripper support together with the sheet forms a straight line.

Die in der deutschen Patentschrift 276 493 genannte Auslage hat den Nachteil, daß durch das Verdrehen der Greiferauflage der gefaßte Bogen bei steifem Material an seinem Ende hochgeschleudert wird und bei elastischem Material der Bogen entsprechend seiner Elastizität sich krümmt, was eine einwandfreie Bogenablage verhindert. Dagegen bildet der Bogen bei der hier beschriebenen Auslage immer eine Gerade. The display mentioned in German Patent 276 493 has the Disadvantage that by twisting the gripper pad the captured bow with stiff Material is thrown up at its end and, in the case of elastic material, the bow bends according to its elasticity, which prevents proper sheet deposition. In contrast, the curve always forms a straight line in the display described here.

Da die unter dem sich auf den Ablagestapel zu bewegenden Bogen befindliche Luft dem Bogen einen Widerstand entgegensetzt, schwingt hinter dem Bogen ein Bogenniederhalter her, welcher den Gegendruck der Luft überwindet und den Bogen einwandfrei zur Ablage bringt. Since the one located under the sheet to be moved onto the discard pile Air the bow one Opposing resistance, a bow hold-down swings behind the bow here, which overcomes the counter pressure of the air and the sheet flawlessly for storage brings.

Claims (1)

Patentanspruch: Bogenauslegevorrichtung für bogenverarbeitende Maschinen, bei der zwischen zwei umlaufenden Ketten Greiferstangen befestigt sind, die den abzulegenden Bogen erfassen, und bei denen ferner zusätzliche Umlenkrollen für die Ketten vorgesehen sind, durch die die Ketten über dem Bogenablegestapel auf diesen zu abgelenkt werden, dadurch gekennzeichnet, daß die Greiferstangen an den Ketten drehbar gelagert sind, daß die Greifer sich auf dem Wege (2) zwischen den zusätzlichen und den Kettenumlenkrollen, welche die Ketten entgegen der Bogenförderrichtung umlenken, öffnen und daß ein Bogenniederhalter hinter dem auf den Ablagestapel zugehenden Bogen herschwingt. Claim: sheet delivery device for sheet processing machines, in which gripper bars are attached between two revolving chains, which the capture sheet to be deposited, and where also additional pulleys for the Chains are provided, through which the chains are placed over the arches on these to be distracted, characterized in that the gripper bars on the chains are rotatably mounted that the gripper on the way (2) between the additional and the chain deflection rollers, which deflect the chains against the sheet conveying direction, open and that a sheet hold-down device behind the one approaching the discard pile Bow swings. In Betracht gezogene Druckschriften: Deutsche Patentschrift Nr. 276 493. Publications considered: German Patent No. 276 493.
