Abstract

The object of the invention is to provide a simple and reliably operating clamping claw (1) for a chain conveyer. To that end, a mobile clamping jaw (6) which can be moved such that it acts against a fixed clamping jaw (4) forms part of a lever arm (18) mounted on a chain link carrier (3). An actuating lever (17) pivots the movable clamping jaw under the effect of a tension spring (26) from a stable open position via an extended dead centre position into a stable closed position. In this respect, in the closed position of the clamping claw, an automatic locking effect acts on a printed product to be conveyed.

Eine Klemmzange 1 für einen beispielsweise einer Rotationsdruckmaschine nachgeschalteten End los f örde re r, z. B. Kettenförderer, besteht im wesentlichen aus einer an einem Kettenglied 2 eines Zugmittels des Kettenförderers mittels eines Trägers 3 befestigten festen ersten Klemmbacke 4 und einer mit der ersten Klemmbacke 4 zusammenwirkenden zweiten Klemmbacke 6. Das Kettenglied 2 weist zumindest beidendig jeweils eine Laufrolle 5 auf, welche in einer nicht dargestellten Kettenführung läuft.A pair of pliers 1 for an end downstream of a rotary printing press, for example, for. B. chain conveyor, consists essentially of a fixed to a chain link 2 of a traction means of the chain conveyor by means of a carrier 3 fixed first jaw 4 and a cooperating with the first jaw 4 second jaw 6. The chain link 2 has at least on both ends a roller 5, which runs in a chain guide, not shown.
Anstelle von Ketten können beispielsweise als Zugmittel auch Seile, Riemen oder Zahnriemen verwendet werden.Instead of chains, ropes, belts or toothed belts can also be used as traction means, for example.
Der Träger 3 der ersten Klemmbacke 4 ist z. B. L-förmig ausgebildet. Ein kurzer Schenkel 7 des Trägers 3 verläuft rechtwinklig zu einer Längsachse 9 des Kettengliedes 2 und ist mit dem Kettenglied 2 verbunden. Ein langer Schenkel 8 des Trägers 3 ist parallel zu der Längsachse 9 des Kettengliedes 2 angeordnet. Ein äußeres Ende 11 des langen Schenkels 8 ist V-förmig ausgebildet und mit der ersten Klemmbacke 4 verbunden. Ein dabei gebildeter Klemmbackengrund 10 weist einen Radius r10 auf. Der Radius r10 ist größer als ein Radius einer Vorderkante 12 eines mittels der Klemmzange 1 transportierten Gutes, z. B. eines Druckproduktes 13 (Fig. 2) .The carrier 3 of the first jaw 4 is z. B. L-shaped. A short leg 7 of the carrier 3 runs at right angles to a longitudinal axis 9 of the chain link 2 and is connected to the chain link 2. A long leg 8 of the carrier 3 is arranged parallel to the longitudinal axis 9 of the chain link 2. An outer end 11 of the long leg 8 is V-shaped and connected to the first jaw 4. A jaw base 10 formed in this way has a radius r10. The radius r10 is larger than a radius of a front edge 12 of a good transported by means of the clamp 1, e.g. B. a printed product 13 (Fig. 2).
Der Träger 3 weist eine rechtwinklig zur Längsachse 9 des Kettengliedes 2 verlaufende Bohrung 14 auf. In dieser Bohrung 14 ist eine Schwenkachse 16 eines HebelsThe carrier 3 has a bore 14 running at right angles to the longitudinal axis 9 of the chain link 2. In this bore 14 is a pivot axis 16 of a lever

18 auf, an dem die anstellbare, schwenkbare Klemmbacke 6 befestigt ist und in den die Bet ät i gungs kräf te eingeleitet werden. Dazu ist der erste Hebelarm 18 an seinem verlängerten, freien Ende mit einer Rolle 19 zur Betätigung des Hebels 17 versehen. Der zweite Hebelarm 22 weist an seinem Ende einen Lagerbolzen 23 auf, welcher als Kraftangriffspunkt 24 für ein Ende einer als Kraft spei eher ausgeführten Zugfeder 26 dient. Die Zugfeder 26 hat an ihrem anderen Ende ein Widerlager 27, welches mit einem am Ende 11 des langen Schenkels 8 befindlichen Lagerbolzen 28 in Wirkverbindung steht.18, on which the adjustable, pivotable jaw 6 is attached and into which the actuating forces are introduced. For this purpose, the first lever arm 18 is provided at its extended, free end with a roller 19 for actuating the lever 17. The second lever arm 22 has at its end a bearing pin 23, which serves as a force application point 24 for one end of a tension spring 26 designed as a force-feeding device. The tension spring 26 has at its other end an abutment 27 which is operatively connected to a bearing pin 28 located at the end 11 of the long leg 8.
Der im Querschnitt L-förmig ausgebildete Träger 3 erstreckt sich in paralleler Richtung zur Schwenkachse 16. Der Träger 3 weist mindestens die Breite eines Kettengliedes 2 auf. Die am Träger 3 befindliche erste Klemmbacke 4 ist breiter, z. B. doppelt so breit wie der Träge r 3.The carrier 3, which is L-shaped in cross section extends in a direction parallel to the pivot axis 16. The carrier 3 has at least the width of a chain link 2. The first jaw 4 located on the carrier 3 is wider, e.g. B. twice as wide as the inertia r 3.
Der Hebel 17 kann auf der Schwenkachse 16 jeweils beidseitig des Trägers 3 angeordnet und mittels der zweiten Klemmbacke 6 verbunden sein. Somit sind auch zwei Zugfedern 26 eingesetzt und jeder der beiden ersten Hebelarme 18 trägt eine Rolle 19. Die zweite Klemmbacke 6 kann an ihrem gegen die Innenseite der ersten Klemmbacke 4 wirkenden Ende mit einem Radius versehen sein. Dadurch werden unerwünschte Prägungen am Druckprodukt 13 vermieden.The lever 17 can be arranged on the pivot axis 16 on both sides of the carrier 3 and connected by means of the second clamping jaw 6. Thus, two tension springs 26 are also used and each of the two first lever arms 18 carries a roller 19. The second clamping jaw 6 can be provided with a radius at its end acting against the inside of the first clamping jaw 4. This avoids undesired embossing on the printed product 13.
Ein Abstand a1 zwischen dem Ende der Klemmbacke 6, d. h. der Berührzone von Druckprodukt 13, und der Schwenkachse 16 der Klemmbacke 6 ist vorzugsweise etwas größer ist als die kürzeste Entfernung zwischen der Schwenkachse 16 und der Innenseite der Klemmbacke 4.A distance a1 between the end of the jaw 6, i. H. the contact zone of the printed product 13, and the pivot axis 16 of the clamping jaw 6 is preferably somewhat larger than the shortest distance between the pivot axis 16 and the inside of the clamping jaw 4.
Die Klemmbacke 6 wird derart an das Druckprodukt 13 angestellt, so daß das Druckprodukt 13 zwischen den beiden Klemmbacken 4, 6 eingeklemmt wird. Dabei wirkt in Schließstellung Selbsthemmung auf das Druckprodukt 13. Dazu schließt eine von dem Ende der Klemmbacke 6, (d. h. der von dem Druckprodukt 13 und der Klemmbacke 6 gebildete Berührzone) und der Schwenkachse 16 der Klemmbacke 6 festgelegte Gerade 33 und eine in einer Berührzone von Druckprodukt 13 und Klemmbacke 4 angelegte Tangente 34 einen Ö fnungswinkel Alpha ein. Vereinfachend wird im folgenden dieser Öffnungswinkel Alpha als der Öffnungswinkel bezeichnet, der von den beiden Klemmbacken 4, 6 eingeschlossen wird. Dieser für vom Klemmbackengrund 10 wegweisende Selbsthemmung notwendige Öffnungswinkel Alpha ist vom Reibungskoeffizienten zwischen Klemmbacken 4, 6 und Druckprodukt 13 abhängig und ist größer 45°, vorzugsweise größer als 60°, und kleiner 90°. Somit kann ein zwischen dem Ende der zweiten Klemmbacke 6 und der Innenseite der ersten Klemmbacke 4 festgehaltenes Druckprodukt 13 nicht herausgezogen werden.The clamping jaw 6 is placed against the printed product 13 in such a way that the printed product 13 is clamped between the two clamping jaws 4, 6. Self-locking acts on the printed product 13 in the closed position. This includes a straight line 33 defined by the end of the clamping jaw 6 (ie the contact zone formed by the printed product 13 and the clamping jaw 6) and the pivot axis 16 of the clamping jaw 6 and one in one Contact zone of the printed product 13 and the clamping jaw 4 created tangent 34 an opening angle alpha. To simplify matters, this opening angle alpha is referred to below as the opening angle enclosed by the two clamping jaws 4, 6. This opening angle alpha, which is necessary for self-locking pointing away from the clamping jaw base 10, depends on the coefficient of friction between the clamping jaws 4, 6 and the printed product 13 and is greater than 45 °, preferably greater than 60 °, and less than 90 °. Thus, a printed product 13 held between the end of the second jaw 6 and the inside of the first jaw 4 cannot be pulled out.
Die Funktion der Klemmzange 1 ist wie nachfolgend beschrieben:The function of the clamp 1 is as follows:
Die an einem Kettenglied 2 des Kettenförderers angeordnete Klemmzange 1 befindet sich zunächst in einer Offenstellung A (Fig. 1). An einer Beladestation, z. B. einem Schaufelrad eines Falzapparates, wird ein Druckprodukt 13 zwischen die Klemmbacken 4, 6 geführt. Infolge der Betätigung des ersten Hebelarmes 18 in Uhrzeigerdrehrichtung D beschreibt der Lagerbolzen 23 mit dem Kraftangriffspunkt 24 einen Kreisbogen um die Schwenkachse 16. Der Radius des Kreisbogens entspricht der Länge des Hebelarmes 22. Dabei passiert der Kraftangriffspunkt 24 der Zugfeder 26 aus einer stabilen Lage A unterhalb einer Tot punkt st e l lung B kommend, eine Totpunkt ste l lung B. Dabei wird die Zugfeder gespannt. Die Tot punkt ste l lung B wird durch eine Gerade 29 dargestellt, welche den Kraftangriffspunkt 24 der Zugfeder 26, die Schwenkachse 16 des Hebels 17 sowie das Widerlager 27 der Zugfeder 26 verbindet. Nach Passieren dieser Totpunkt st e l lung B zieht sich die Zugfeder 26 wieder zusammen. Das freie Ende der zweiten Klemmbacke 6 legt sich an das Druckprodukt 13 in Schließstellung C an (Fig. 2) .The clamping tongs 1 arranged on a chain link 2 of the chain conveyor are initially in an open position A (FIG. 1). At a loading station, e.g. B. a paddle wheel of a folder, a printed product 13 is guided between the jaws 4, 6. As a result of the actuation of the first lever arm 18 in the clockwise direction of rotation D, the bearing pin 23 describes a circular arc around the pivot axis 16 with the force application point 24. The radius of the circular arc corresponds to the length of the lever arm 22. The force application point 24 of the tension spring 26 passes from a stable position A below a dead center position B coming, a dead center position B. The tension spring is tensioned. The dead center position B is represented by a straight line 29 which connects the force application point 24 of the tension spring 26, the pivot axis 16 of the lever 17 and the abutment 27 of the tension spring 26. After passing this dead center position B, the tension spring 26 contracts again. The free end of the second jaw 6 lies against the printed product 13 in the closed position C (FIG. 2).
Die stabilen Lagen in Offen- und Schließstellung A, C der zweiten Klemmbacke 6 werden dadurch erreicht, daß ein Abstand zwischen Kraftangriffspunkt 24 und Widerlager 27 der Zugfeder 26 in Offen- und Schließstellung A, C kleiner ist als die Länge der Tot punkt st rec ke, d. h. dieses Abstandes in Totpunkt ste l lung B. Die Klemmbacke 6 wird also in Offen- und Schließstellung und schließlich durch den Kraft spei eher 26 gehalten, d. h. ohne permanente Einwirkungen z. B. einer Kurvensteuerung. Die Dicke des Druckproduktes 13 kann zwischen 0,1 mm und mehreren Mi 11 i metern li egen.The stable positions in the open and closed position A, C of the second clamping jaw 6 are achieved in that a distance between the force application point 24 and the abutment 27 of the tension spring 26 in the open and closed position A, C is smaller than the length of the dead point st rec ke , d. H. of this distance in dead center position B. The clamping jaw 6 is thus held in the open and closed position and finally by the power supply rather 26, d. H. without permanent influences e.g. B. a curve control. The thickness of the printed product 13 can lie between 0.1 mm and several millimeters.
Wenn das Druckprodukt 13 wieder freigegeben werden soll, so wird der erste Hebelarm 18 entgegen der Uhrzeigerdrehrichtung E betätigt (Fig. 2). Nach überschreiten der Tot punkt st e l lung B wird wiederum eine stabile Lage der zweiten Klemmbacke 6 in Offenstellung A e i ngenom en .When the printed product 13 is to be released again, the first lever arm 18 is actuated in the counterclockwise direction of rotation E (FIG. 2). After the dead center position B has been exceeded, a stable position of the second clamping jaw 6 in the open position A is again achieved.
Nach einer zweiten Ausfü rungsvariante ist dem ersten Hebelarm 18 eines Hebels 32 eine weitere Rolle 31 zugeordnet. Diese Rolle 31 ist zwischen der ersten Rolle 19 und der Klemmbacke 6 angeordnet. Die Anordnung einer zur Rolle 19 zusätzlichen Rolle 31 ist insofern vorteilhaft, als daß das Schalten der zweiten Klemmbacke 6 in die Endstellung A, C über verschiedene Rollen 19, 31 vorgenommen werden kann.According to a second embodiment, a further roller 31 is assigned to the first lever arm 18 of a lever 32. This roller 31 is arranged between the first roller 19 and the jaw 6. The arrangement of a roller 31 which is additional to the roller 19 is advantageous in that the switching of the second clamping jaw 6 into the end position A, C can be carried out via different rollers 19, 31.
Anstelle des zwei Hebelarme aufweisenden Hebels 17, 31 kann auch nur ein einziger Hebelarm vorgesehen sein. An diesen einzigen Hebelarm ist dann die anstellbare Klemmbacke 6 befestigt und es werden die Betätigungskräfte für die Bewegung der Klemmbacke 6 in ihre Offen- und Schließstellung sowie die Klemmkräfte eingeleitet. Instead of the lever 17, 31 having two lever arms, only a single lever arm can also be provided. The adjustable clamping jaw 6 is then attached to this single lever arm and the actuating forces for the movement of the clamping jaw 6 into its open and closed positions as well as the clamping forces are introduced.
