Definitions
- the invention relates to a folder, in which the transport of the folded copies is carried out by means of transport, tape rolls and tapes.
- the folded copies initially transported at high speeds in the folder must be braked for further processing, in particular for the second longitudinal fold formation, so that e.g. during the folding process no paper jam occurs.
- Brush devices that act on the specimen or suction devices that apply a decelerating force to the specimen are known which serve to reduce the speed.
- Slow-down cylinders are also used to reduce the speed in order to reduce the speed of the folded copy.
- two deceleration cylinders which feed the fold copy to the second longitudinal fold formation, are arranged one behind the other.
- the speed per cylinder is reduced by 30%.
- Conveyor belt assemblies are also known which operate at fast and slow speeds. The folded copies are transported from the fast to the slow belts and picked up by them.
- the object of the invention is to eliminate the disadvantages of the prior art.
- the advantage of this solution is that the fold copies arriving on the first belt arrangement are not abruptly braked due to the variable speed during the transition from the first to the second belt arrangement, and that the fold copies are kept and guided continuously on the transport route.
- Fig. 1 has such a folder with which an endless paper web previously printed in a printing press is folded.
- This folder consists of the former (1) over which the printed paper web runs by forming a first longitudinal fold which is parallel to the edge strips of the paper extends, the two edges of the web width lying one above the other.
- the web (8) thus folded passes through the funnel folding rollers for the purpose of forming the first longitudinal fold as well as through the pair of transverse perforating cylinders (2A, 2B) which perforate the web at the point at which the first transverse fold is later to be found.
- the web then continues between the cutting cylinder (3) and the collecting or transfer cylinder (4).
- the cutting cylinder (3) is provided with cutting knives (9A, 9B) which are arranged on the surface line of this cylinder and which cooperate with cutting knife counterparts which are provided on the collecting or transfer cylinder (4) around the longitudinally folded web (8 ) to cut.
- Punctures (11A, 11B, 11C) hold the top of the specimen so cut by indenting near the leading edge of the specimen.
- Folding knives (12A, 12B, 12C) guide the specimen with the center into the folding jaws (13A, 13B, 13C, 13D), which are provided on a folding jaw cylinder (5).
- the decelerating cylinders (6A, 6B) alternately record the specimens that run successively over the cylinder (5).
- the deceleration cylinder (6A) is provided with grippers (14A, 14B) and the deceleration cylinder (6B) with grippers (14A ', 14B').
- These cylinders are called slowdown cylinders because they rotate at the same angular velocity as the cylinder (5); however, they have a smaller diameter, so that they consequently have a lower linear velocity.
- the device is designed in such a way that the gripper (14B) of the upper decelerating cylinder grips the copy located in the folding flap (13D) and that the gripper (14A) the copy located in the folding flap (13B) on the first transverse fold edge detected.
- the gripper (14A ') on the first transverse fold edge of the lower decelerating cylinder comprises the specimen located in the folding flap (13C) and the gripper (14B') the specimen located in the folding flap (13A).
- These slowdown cylinders are followed by belts or belts running in parallel, which grasp the once folded copy and feed it to a device (7A) which works together with the slowdown cylinder (6A) and a device (7B) which works together with the slowdown cylinder (6B) .
- a belt arrangement (15) consisting of four belts is provided below the copy coming from the cylinder.
- the bands (16) (Fig. 2) are arranged above the specimen. This belt arrangement detaches the specimen from the deceleration cylinder (6A or 6B) and conveys it until it comes into contact with the stop (17), where it is stopped by sliding between the belts.
- the stop (17) is comb-shaped; in its lower part it consists of four recesses (18) which allow the bands (15, 16) to pass freely.
- Two folding rollers (21A, 21B), which - as shown in FIG. 3 - rotate in the opposite direction, are arranged under the folding table (19) opposite the gap (20).
- the entire kinematic chain is designed in such a way that the folding knife (22) is in a lower position shortly after the arrival of a folding copy (27) on the stop (17).
- rollers (21A, 21B) thus grasp the specimen and fold it perpendicular to the fold formed between the cylinders (4, 5). This second longitudinal fold is also called "sword fold".
- Fig. 5 shows a possible division of the copies in such a folder.
- Fig. 5a it can be seen how the paper web - cut but not folded - is wound around the collecting cylinder (4).
- Each copy has a length C; and the distance between two successive specimens is also C.
- Fig. 5b shows the copies lying on the cylinder (5) after the folding process. The distance between two copies is still C, but the length of each copy is only C / 2 after the copy has been folded in half.
- Figure 5c shows the only non-hatched specimens on the deceleration cylinder (6A) prior to deceleration. The distance is now 2C and the copy length C / 2.
- 5d shows the specimens transported to the deceleration cylinder (6A) after a deceleration of 25% (3/4 of the distance between two specimen spines remains). The distance is 6C / 4 and the copy length C / 2.
- Figures 5e and 5f show the operations on the slowdown cylinder (6B), which are identical to those on the slowdown cylinder (6A), with respect to the hatched specimens of Figure 5b.
- the distance between two consecutive copies in the usual second longitudinal fold must be at least C if the copy length is C / 2.
- FIG. 6 shows a device according to the invention. Above all, a sequence of specimens can be seen, the specimen (27) between two belt arrangements, ie between the high-speed upper (28) and the high-speed lower belts (29) is clamped, these tapes wrapped around the deceleration cylinder having a peripheral speed which corresponds to that of the deceleration cylinder.
- the copy (27 ') is also clamped between two slow belt arrangements (30, 31) rotating at half the machine speed, which transport the copy up to the stop of the sword fold.
- the slow moving upper belt assemblies bear the reference number (30) and the slow moving lower belt assemblies the reference number (31).
- a device consisting of a roller (33) which is mounted in an oscillating manner at the end of a lever (34) and whose longitudinal position is adjusted by means of an adjusting wheel (35) which is connected to a screw-nut connection (36). acts to set the position of the last gripping movement of a signature between the fast bands.
- a device (33 ', 34', 35 ', 36') which is identical in all points makes it possible to adjust the position in which the gripping movement between the slow belts begins.
- FIG. 7 is a top view of FIG. 6.
- Fig. 7 it can be seen that the belts (31) are wrapped around guide rollers (43) which have a smaller diameter than the partially rubber-coated belt rollers (38) and which are movably mounted on the shaft (40).
- the belts (30) are also wrapped around the guide rollers (42), which are movably supported on the shaft (39) between the partially rubber-coated belt rollers (37).
- the shaft (39) is rotatably mounted on two levers (44, 44 ') which are articulated to the frame via a geometric axis (45).
- Fig. 8 shows the entire drive with a cyclically variable speed.
- This drive consists of the following components: an intermediate shaft (48) by the main control of the machine is driven via a roller (49) and a toothed belt (51).
- the entire drive is designed such that the disk (52) which is arranged at the end of the shaft (48) makes one revolution each time the folder produces a copy (27).
- the disk (52) drives an opposite disk 53) by means of a cam roller (54) which is fastened on the disk (52) and which runs in a guide groove (55) provided in the disk (53).
- the disc (53) itself is connected to the output shaft (40) which carries a gearwheel (57) attached to it and which also drives the lower belt rollers (38), which are partially covered with rubber.
- the gearwheel (57) is connected to a further gearwheel (58) which has the same diameter and is fastened on the shaft (39) by means of two small gearwheels (59, 60) located in between.
- the gear drives the upper band rollers (37).
- the device ensures the synchronous drive of the upper and lower belt rolls by allowing the setting of the pressure force between said upper and lower belt rolls.
- the lower and upper partially rubber-coated tape rolls (37, 38) are fastened in such a way that the rubber-coated parts - which consequently have a larger diameter - are exactly in phase, i.e. the beginning and end of the rubber layer pass the connecting line of the center points ( 39, 40), namely that of the upper and lower band rolls at the same time, as a result of which the specimen (27) located between them is clamped or released at the same time.
- Fig. 9 has a diagram in which two curves (70, 71) are shown.
- the rotation angle A of -90 ° to + 360 ° of the drive shaft (48) of the device of FIG. 8 is plotted on the abscissa.
- the rotation angle B of the output shaft (40) is plotted on the ordinate.
- the curve (70) represents the exit angle as a function of the entry angle.
- the curve (71), which is shown in the same diagram, is the derivative of the curve (70) and gives the relationship between the exit angle speed and the entry angle speed in all points of the device shown in FIG.
- the curve (71) thus shows the change in circumferential speed of the belt rolls (37, 38), which are partially covered with rubber, as a function of their angular rotation.
- the device works in the following way: A specimen (27) is pushed by the fast belts (28, 29) between the two partly rubber-coated belt rolls (37, 38) at the speed of the fast belts (see FIG. 9, straight line) 72). If this example exceeds the connecting line of the center points (39, 40) by a few centimeters, the partially coated rubber rolls (37, 38) come to the point during their rotational movement, at which these are covered with rubber and at this point the tape rolls reach their top speed.
- the signature thus reaches the speed of these partially rubber-coated tape rolls, which corresponds to that of the fast tapes (straight line 72).
- the adjusting wheels (35) on the fast and slow belts have the task of setting the exact point at which the belts capture or release the copy.
- Fig. 10 has a folder according to the invention, which consists of two separate belt arrangements, the slowdown cylinders are subordinate.
- This folder is suitable for the formation of an upper sword fold as well as a lower sword fold.
- FIG. 11 Such a folder is shown in Fig. 11.
- the specimen (27) is therefore taken directly from the folding jaw cylinder (5) by the fast belt arrangements.
- the eccentricity between the shafts (40, 48) and the radius of rotation of the axis of the cam roller (54) around the shaft (48) are thus adjusted in order to reduce the speed of the partially coated rubber rollers by 50%.
- the slow belts rotate half as fast as the fast belts.
- a device is also conceivable with which folding copies of a variable folding apparatus - as used in gravure printing - or a completely different type of folding apparatus are slowed down.

Abstract
Description
Die Erfindung betrifft einen Falzapparat, bei dem der Transport der Falzexemplare über Transportmittel, Bandrollen und Bänder erfolgt.The invention relates to a folder, in which the transport of the folded copies is carried out by means of transport, tape rolls and tapes.
Die im Falzapparat anfänglich mit hohen Geschwindigkeiten transportierten Falzexemplare müssen zur Weiterverarbeitung, insbesondere für die zweite Längsfalzbildung, abgebremst werden, damit während des Falzvorganges z.B. kein Papierstau auftritt. Es sind Bürsteneinrichtungen, die auf das Exemplar einwirken, oder Ansaugeinrichtungen, die auf das Exemplar eine Verlangsamungskraft ausüben, bekannt, die der Geschwindigkeitsreduzierung dienen.The folded copies initially transported at high speeds in the folder must be braked for further processing, in particular for the second longitudinal fold formation, so that e.g. during the folding process no paper jam occurs. Brush devices that act on the specimen or suction devices that apply a decelerating force to the specimen are known which serve to reduce the speed.
Auch werden zur Geschwindigkeitsreduzierung Verlangsamungszylinder eingesetzt, um die Geschwindigkeit des Falzexemplares herabzusetzen. So werden beispielsweise zwei Verlangsamungszylinder, die das Falzexemplar der zweiten Längsfalzbildung zuführen, hintereinander angeordnet. Dabei wird die Geschwindigkeit pro Zylinder um 30 % verringert. Diese Lösung hat den Nachteil, daß ihre Realisierung kompliziert und somit teuer ist.Slow-down cylinders are also used to reduce the speed in order to reduce the speed of the folded copy. For example, two deceleration cylinders, which feed the fold copy to the second longitudinal fold formation, are arranged one behind the other. The speed per cylinder is reduced by 30%. This solution has the disadvantage that its implementation is complicated and therefore expensive.
Es sind auch Transportbänderanordnungen bekannt, die mit einer schnellen und einer langsamen Geschwindigkeit arbeiten. Die Falzexemplare werden dabei von den schnellen zu den langsamen Bändern transportiert und von diesen aufgenommen.Conveyor belt assemblies are also known which operate at fast and slow speeds. The folded copies are transported from the fast to the slow belts and picked up by them.
Diese Lösung hat den Nachteil, daß das Falzexemplar eine Geschwindigkeitsänderung erfährt, die sich abrupt und ohne Übergang vollzieht, und daß die Falzexemplare zum Teil unkontrolliert und nicht präzise transportiert werden, was zu Ungenauigkeiten und Papierstaus führen kann.This solution has the disadvantage that the folded copy experiences a speed change that occurs abruptly and without transition, and that the folded copies are sometimes transported in an uncontrolled and imprecise manner, which can lead to inaccuracies and paper jams.
Die Aufgabe der Erfindung ist es, die Nachteile des Standes der Technik zu beseitigen.The object of the invention is to eliminate the disadvantages of the prior art.
Die Aufgabe wird durch einen Falzapparat einer Druckmaschine gelöst, bei dem der Transport der Falzexemplare über Transportmittel, Bandrollen und Bänder erfolgt und folgende Merkmale aufweist:
- es ist eine schnell laufende erste Bänderanordnung bestehend aus oberen und unteren Bändern vorgesehen, zwischen denen das Falzexemplar transportiert wird,
- es ist eine mit variabler Geschwindigkeit antreibbare Bandrollenanordnung bestehend aus oberen und unteren Bandrollen vorgesehen, die das von der ersten Bänderanordnung herangeführte Falzexemplar im Bereich dessen Vorderkante aufnehmen und weitertransportieren,
- es ist eine langsam laufende zweite Bänderanordnung bestehend aus oberen und unteren Bändern vorgesehen, die das aus den Bandrollen herausgeführte Falzexemplar an dessen Vorderkante aufnehmen und weitertransportieren.
- there is a fast-running first belt arrangement consisting of upper and lower belts, between which the folded copy is transported,
- there is provided a belt roll arrangement which can be driven at variable speed and which comprises upper and lower belt rolls which receive and transport the folded copy brought up by the first belt arrangement in the region of the front edge thereof,
- a slow-running second belt arrangement consisting of upper and lower belts is provided, which receive and transport the folded copy out of the belt rolls at its front edge.
Der Vorteil dieser Lösung ist darin zu sehen, daß die auf der ersten Bänderanordnung ankommenden Falzexemplare aufgrund der variablen Geschwindigkeit beim Übergang von der ersten zur zweiten Bänderanordnung nicht abrupt abgebremst werden, und daß die Falzexemplare auf der Transportstrecke kontinuierlich gehalten und geführt werden.The advantage of this solution is that the fold copies arriving on the first belt arrangement are not abruptly braked due to the variable speed during the transition from the first to the second belt arrangement, and that the fold copies are kept and guided continuously on the transport route.
Weitere vorteilhafte, erfinderische Merkmale enthaltende Ausführungsformen ergeben sich aus der nachfolgenden Beschreibung und den Abbildungen der beigefügten Zeichnung:Further advantageous embodiments containing inventive features result from the following description and the figures of the accompanying drawing:
Fig. 1 weist einen derartigen Falzapparat auf, mit dem eine zuvor in einer Druckmaschine bedruckte Endlospapierbahn gefalzt wird.Fig. 1 has such a folder with which an endless paper web previously printed in a printing press is folded.
Dieser Falzapparat besteht aus dem Falztrichter (1), über den die bedruckte Papierbahn läuft, indem ein erster Längsfalz gebildet wird, der sich parallel zu den Randstreifen des Papiers erstreckt, wobei die beiden Kanten der Bahnbreite übereinander liegen.This folder consists of the former (1) over which the printed paper web runs by forming a first longitudinal fold which is parallel to the edge strips of the paper extends, the two edges of the web width lying one above the other.
Die so gefalzte Bahn (8) durchläuft die Trichterfalzwalzen zwecks erster Längsfalzbildung sowie das Querperforierzylinderpaar (2A, 2B), das die Bahn an der Stelle, an der sich später der erste Querfalz befindet, perforiert. Die Bahn läuft dann zwischen dem Schneidzylinder (3) und dem Sammel- oder Transferzylinder (4) hindurch weiter.The web (8) thus folded passes through the funnel folding rollers for the purpose of forming the first longitudinal fold as well as through the pair of transverse perforating cylinders (2A, 2B) which perforate the web at the point at which the first transverse fold is later to be found. The web then continues between the cutting cylinder (3) and the collecting or transfer cylinder (4).
Der Schneidzylinder (3) ist mit Schneidmessern (9A, 9B) versehen, die an der Mantellinie dieses Zylinders angeordnet sind und die mit Schneidmesser-Gegenstücken zusammenarbeiten, die auf dem Sammel- oder Transferzylinder (4) vorgesehen sind, um die längsgefalzte Bahn (8) zu schneiden.The cutting cylinder (3) is provided with cutting knives (9A, 9B) which are arranged on the surface line of this cylinder and which cooperate with cutting knife counterparts which are provided on the collecting or transfer cylinder (4) around the longitudinally folded web (8 ) to cut.
Punkturen (11A, 11B, 11C) halten den oberen Teil des so abgeschnittenen Exemplars fest, indem sie sich in der Nähe der Vorderkante des Exemplars eindrücken.Punctures (11A, 11B, 11C) hold the top of the specimen so cut by indenting near the leading edge of the specimen.
Falzmesser (12A, 12B, 12C) führen das Exemplar mit der Mitte in die Falzklappen (13A, 13B, 13C, 13D), die auf einem Falzklappenzylinder (5) vorgesehen sind.Folding knives (12A, 12B, 12C) guide the specimen with the center into the folding jaws (13A, 13B, 13C, 13D), which are provided on a folding jaw cylinder (5).
Drehen sich die Zylinder in Pfeilrichtung, wird das Exemplar gefalzt und in die Falzklappen (13) geklemmt.If the cylinders turn in the direction of the arrow, the copy is folded and clamped in the jaws (13).
Die Verlangsamungszylinder (6A, 6B) erfassen abwechselnd die Exemplare, die nacheinander über den Zylinder (5) laufen. Der Verlangsamungszylinder (6A) ist mit Greifern (14A, 14B) und der Verlangsamungszylinder (6B) mit Greifern (14A', 14B') versehen.The decelerating cylinders (6A, 6B) alternately record the specimens that run successively over the cylinder (5). The deceleration cylinder (6A) is provided with grippers (14A, 14B) and the deceleration cylinder (6B) with grippers (14A ', 14B').
Diese Zylinder werden Verlangsamungszylinder genannt, da die sich mit derselben Winkelgeschwindigkeit drehen wie der Zylinder (5); sie haben jedoch einen kleineren Durchmesser, so daß sie folglich eine geringere Lineargeschwindigkeit aufweisen.These cylinders are called slowdown cylinders because they rotate at the same angular velocity as the cylinder (5); however, they have a smaller diameter, so that they consequently have a lower linear velocity.
Die Vorrichtung ist derart ausgebildet, daß der Greifer (14B) des oberen Verlangsamungszylinders das Exemplar erfaßt, das sich in der Falzklappe (13D) befindet, und daß der Greifer (14A) das sich in der Falzklappe (13B) befindende Exemplar an der ersten Querfalzkante erfaßt.The device is designed in such a way that the gripper (14B) of the upper decelerating cylinder grips the copy located in the folding flap (13D) and that the gripper (14A) the copy located in the folding flap (13B) on the first transverse fold edge detected.
Genauso umfaßt der Greifer (14A') an der ersten Querfalzkante des unteren Verlangsamungszylinders das sich in der Falzklappe (13C) befindende Exemplar und der Greifer (14B') das sich in der Falzklappe (13A) befindende Exemplar. Diesen Verlangsamungszylindern sind parallel laufende Riemen oder Bänder nachgeordnet, die das einmal gefalzte Exemplar erfassen und dieses einer Vorrichtung (7A), welche mit dem Verlangsamungszylinder (6A) zusammenarbeitet, und einer Vorrichtung (7B), die mit dem Verlangsamungszylinder (6B) zusammenarbeitet, zuführen.Likewise, the gripper (14A ') on the first transverse fold edge of the lower decelerating cylinder comprises the specimen located in the folding flap (13C) and the gripper (14B') the specimen located in the folding flap (13A). These slowdown cylinders are followed by belts or belts running in parallel, which grasp the once folded copy and feed it to a device (7A) which works together with the slowdown cylinder (6A) and a device (7B) which works together with the slowdown cylinder (6B) .
Anhand von Figg. 2, 3, 4 ist die Arbeitsweise dieser Vorrichtungen, die Zweite-Längsfalz- oder Schwertfalz-Vorrichtungen genannt werden, besser zu verstehen.

In den Figg. 2 bis 4 ist unterhalb des von dem Zylinder kommenden Exemplars eine aus vier Bändern bestehende Bänderanordnung (15) vorgesehen.In the Fig. 2 to 4, a belt arrangement (15) consisting of four belts is provided below the copy coming from the cylinder.
Die Bänder (16) (Fig. 2) sind oberhalb des Exemplars angeordnet. Diese Bänderanordnung löst das Exemplar von dem Verlangsamungszylinder (6A oder 6B) ab und befördert es solange, bis es mit dem Anschlag (17) in Kontakt kommt, wo es gestoppt wird, indem es zwischen die Bänder rutscht.The bands (16) (Fig. 2) are arranged above the specimen. This belt arrangement detaches the specimen from the deceleration cylinder (6A or 6B) and conveys it until it comes into contact with the stop (17), where it is stopped by sliding between the belts.
Der Anschlag (17) ist kammförmig ausgebildet; in seinem unteren Teil besteht dieser aus vier Aussparungen (18), die den Bändern (15, 16) freien Durchgang ermöglichen.The stop (17) is comb-shaped; in its lower part it consists of four recesses (18) which allow the bands (15, 16) to pass freely.
Ein Falztisch (19), in dessen Mitte ein Spalt (20) vorgesehen ist, ist unterhalb der Bänder (15) angeordnet, die auf dem Falztisch (19) leicht aufliegen.A folding table (19), in the middle of which a gap (20) is provided, is arranged below the belts (15), which rest slightly on the folding table (19).
Zwei Falzwalzen (21A, 21B), die sich - wie in Fig. 3 gezeigt - in entgegengesetzter Richtung drehen, sind unter dem Falztisch (19) gegenüber dem Spalt (20) angeordnet.Two folding rollers (21A, 21B), which - as shown in FIG. 3 - rotate in the opposite direction, are arranged under the folding table (19) opposite the gap (20).
Ein Falzmesser (22), das am Ende eines um eine Achse (24) beweglichen Armes (23) befestigt ist, wird durch Hin- und Herbewegung mittels einer Kurbelstange (25) und einer Kurbel (26) angetrieben.A folding knife (22), which is attached to the end of an arm (23) movable about an axis (24), is driven by reciprocating movement by means of a crank rod (25) and a crank (26).
Die gesamte kinematische Kette ist derart ausgebildet, daß das Falzmesser (22) sich kurz nach dem Ankommen eines Falzexemplars (27) an dem Anschlag (17) in einer unteren Position befindet.The entire kinematic chain is designed in such a way that the folding knife (22) is in a lower position shortly after the arrival of a folding copy (27) on the stop (17).
Die Walzen (21A, 21B) erfassen also das Exemplar und falzen es senkrecht zu dem zwischen den Zylindern (4, 5) gebildeten Falz. Dieser zweite Längsfalz wird auch "Schwertfalz" genannt.The rollers (21A, 21B) thus grasp the specimen and fold it perpendicular to the fold formed between the cylinders (4, 5). This second longitudinal fold is also called "sword fold".
Diese gesamte Vorrichtung, die Kinematik einer solchen Maschine und deren verschiedene Einstellungen sind dem Fachmann bekannt, so daß wir darauf nicht weiter eingehen werden.This entire device, the kinematics of such a machine and its various settings are known to the person skilled in the art, so that we will not go into this in any further detail.
Fig. 5 zeigt eine mögliche Aufteilung der Exemplare in einem derartigen Falzapparat.Fig. 5 shows a possible division of the copies in such a folder.
In Fig. 5a ist zu sehen, wie die Papierbahn - abgeschnitten, aber nicht gefalzt - um den Sammelzylinder (4) geschlungen ist. Jedes Exemplar weist eine Länge C auf; und der Abstand zwischen zwei aufeinanderfolgenden Exemplaren beträgt auch C.In Fig. 5a it can be seen how the paper web - cut but not folded - is wound around the collecting cylinder (4). Each copy has a length C; and the distance between two successive specimens is also C.
Fig. 5b zeigt die auf dem Zylinder (5) liegenden Exemplare nach dem Falzvorgang. Der Abstand zwischen zwei Exemplaren ist immer noch C, aber die Länge eines jeden Exemplars beträgt nur C/2, nachdem das Exemplar in zwei Hälften gefalzt wurde.Fig. 5b shows the copies lying on the cylinder (5) after the folding process. The distance between two copies is still C, but the length of each copy is only C / 2 after the copy has been folded in half.
Fig. 5c weist die einzigen nicht schraffierten Exemplare auf dem Verlangsamungszylinder (6A) vor der Verlangsamung auf. Der Abstand beträgt nun 2C und die Exemplarlänge C/2.Figure 5c shows the only non-hatched specimens on the deceleration cylinder (6A) prior to deceleration. The distance is now 2C and the copy length C / 2.
Fig. 5d weist die zum Verlangsamungszylinder (6A) transportierten Exemplare nach einer Verlangsamung von 25 % auf (es bleibt 3/4 des Abstandes zwischen zwei Exemplarrücken). Der Abstand beträgt 6C/4 und die Exemplarlänge C/2.5d shows the specimens transported to the deceleration cylinder (6A) after a deceleration of 25% (3/4 of the distance between two specimen spines remains). The distance is 6C / 4 and the copy length C / 2.
Fig. 5e und 5f zeigen die Vorgänge auf dem Verlangsamungszylinder (6B), die mit denen auf dem Verlangsamungszylinder (6A) identisch sind, in bezug auf die schraffierten Exemplare von Fig. 5b.Figures 5e and 5f show the operations on the slowdown cylinder (6B), which are identical to those on the slowdown cylinder (6A), with respect to the hatched specimens of Figure 5b.
Es ist zu bemerken, daß bei einer Schwertfalzvorrichtung ein ausreichender Abstand zwischen zwei aufeinanderfolgenden Exemplaren vorhanden sein muß. Da das Falzen in der Tat kein fortlaufender Vorgang ist und das Exemplar während des Falzvorgangs an dem Anschlag (17) festgehalten wird, kann das nachfolgende Exemplar, das seinen Vorsprung zwischen den beiden Bänderanordnungen behält, mit dem gerade gefalzten Exemplar kollidieren.It should be noted that with a sword folding device there must be a sufficient distance between two successive copies. Since the folding is in fact not an ongoing process and the specimen is held by the stopper (17) during the folding process, the succeeding specimen may have its projection between the two Keeps ribbon arrangements, collide with the just folded copy.
In der Praxis muß der Abstand zwischen zwei aufeinanderfolgenden Exemplaren beim gewöhnlichen zweiten Längsfalz mindestens C entsprechen, wenn die Exemplarlänge C/2 beträgt.In practice, the distance between two consecutive copies in the usual second longitudinal fold must be at least C if the copy length is C / 2.
Das bedeutet, daß bei Schwertfalz-Vorrichtungen eine Verlangsamung von 50 % nicht überschritten werden darf. Es ist außerdem sehr schwer, eine solche Verlangsamung mit einem einzigen Verlangsamungszylinder zu erreichen.This means that a slowdown of 50% must not be exceeded with sword folding devices. It is also very difficult to achieve such a slowdown with a single slowdown cylinder.
Fig. 6 zeigt eine erfindungsgemäße Vorrichtung. Vor allem ist eine Folge von Exemplaren zu sehen, wobei das Exemplar (27) zwischen zwei Bänderanordnungen d.h. zwischen die schnell laufenden oberen (28) und die schnell laufenden unteren Bänder
(29) geklemmt ist, wobei diese um den Verlangsamungszylinder geschlungenen Bänder eine Umfangsgeschwindigkeit aufweisen, die der des Verlangsamungszylinders entspricht.6 shows a device according to the invention. Above all, a sequence of specimens can be seen, the specimen (27) between two belt arrangements, ie between the high-speed upper (28) and the high-speed lower belts
(29) is clamped, these tapes wrapped around the deceleration cylinder having a peripheral speed which corresponds to that of the deceleration cylinder.
Das Exemplar (27') ist auch zwischen zwei langsame mit halber Maschinengeschwindigkeit umlaufende Bänderanordnungen (30, 31) geklemmt, die das Exemplar bis zum Anschlag des Schwertfalzes transportieren. Die langsam laufenden oberen Bänderanordnungen tragen die Bezugsziffer (30) und die langsam laufenden unteren Bänderanordnungen die Bezugsziffer (31).The copy (27 ') is also clamped between two slow belt arrangements (30, 31) rotating at half the machine speed, which transport the copy up to the stop of the sword fold. The slow moving upper belt assemblies bear the reference number (30) and the slow moving lower belt assemblies the reference number (31).
Diese vier Bänderanordnungen sind um Umlenkrollen (32), die in ausreichender Anzahl vorhanden sind, geschlungen.These four belt arrangements are wound around deflection rollers (32), which are available in sufficient numbers.
Außerdem ermöglicht es eine Vorrichtung, die aus einer am Ende eines Hebels (34) oszillierend angebrachten Walze (33) besteht, deren Längsposition über ein Verstellrad (35) verstellt wird, das auf eine Schrauben-Mutter-Verbindung (36) einwirkt, die Position der letzten Greifbewegung einer Signatur zwischen den schnellen Bändern einzustellen.It also enables a device consisting of a roller (33) which is mounted in an oscillating manner at the end of a lever (34) and whose longitudinal position is adjusted by means of an adjusting wheel (35) which is connected to a screw-nut connection (36). acts to set the position of the last gripping movement of a signature between the fast bands.
Eine in allen Punkten identische Vorrichtung (33', 34', 35', 36') ermöglicht das Verstellen der Position, in der die der Greifbewegung zwischen den langsamen Bändern einsetzt.A device (33 ', 34', 35 ', 36') which is identical in all points makes it possible to adjust the position in which the gripping movement between the slow belts begins.
Die auf ihrem Kreisumfang nur teilweise mit Gummi überzogenen Bandrollen (37, 38) werden auf den Wellen (39, 40) befestigt.The band rolls (37, 38), which are only partially covered with rubber on their circumference, are fastened to the shafts (39, 40).
Fig. 7 ist eine Draufsicht von Fig. 6.7 is a top view of FIG. 6.
In Fig. 7 ist zu sehen, daß die Bänder (31) um Leitwalzen (43) geschlungen sind, die einen kleineren Durchmesser haben als die teilweise mit Gummi überzogenen Bandrollen (38) und die beweglich auf der Welle (40) gelagert sind.In Fig. 7 it can be seen that the belts (31) are wrapped around guide rollers (43) which have a smaller diameter than the partially rubber-coated belt rollers (38) and which are movably mounted on the shaft (40).
Ebenso sind die Bänder (30) um die Leitwalzen (42), die beweglich auf der Welle (39) zwischen den teilweise mit Gummi überzogenen Bandrollen (37) gelagert sind, geschlungen. Die Welle (39) ist drehbar auf zwei Hebeln (44, 44') gelagert, die mit dem Gestell über eine geometrische Achse (45) gelenkig verbunden sind.The belts (30) are also wrapped around the guide rollers (42), which are movably supported on the shaft (39) between the partially rubber-coated belt rollers (37). The shaft (39) is rotatably mounted on two levers (44, 44 ') which are articulated to the frame via a geometric axis (45).
Das Ganze wird mittels einer von einem Pneumatikzylinder (46) gelieferten Kraft in Position gehalten, indem die Kraft den Hebel (44) gegen einen verstellbaren Anschlag (47) drückt, welcher an dem Gestell befestigt ist. Dies ermöglicht es, eine feste Position und einen konstanten Abstand zwischen den Wellen (39, 40) aufrechtzuerhalten.The whole is held in position by means of a force supplied by a pneumatic cylinder (46), in that the force presses the lever (44) against an adjustable stop (47) which is attached to the frame. This enables a fixed position and a constant distance between the shafts (39, 40) to be maintained.
Fig. 8 zeigt den gesamten Antrieb mit einer zyklisch variablen Geschwindigkeit.Fig. 8 shows the entire drive with a cyclically variable speed.
Dieser Antrieb besteht aus folgenden Bestandteilen: einer Zwischenwelle (48), die von der Hauptsteuerung der Maschine über eine Rolle (49) und einem Zahnriemen (51) angetrieben wird. Der gesamte Antrieb ist derart ausgebildet, daß die Scheibe (52) die am Ende der Welle (48) angeordnet ist, jedesmal eine Umdrehung macht, wenn der Falzapparat ein Exemplar (27) hervorbringt.This drive consists of the following components: an intermediate shaft (48) by the main control of the machine is driven via a roller (49) and a toothed belt (51). The entire drive is designed such that the disk (52) which is arranged at the end of the shaft (48) makes one revolution each time the folder produces a copy (27).
Die Scheibe (52) treibt eine ihr gegenüberliegende Scheibe 53) mittels einer Kurvenrolle (54) an, die auf der Scheibe (52) befestigt ist und die in einer in der Scheibe (53) vorgesehenen Führungsnut (55) läuft.The disk (52) drives an opposite disk 53) by means of a cam roller (54) which is fastened on the disk (52) and which runs in a guide groove (55) provided in the disk (53).
Die Scheibe (53) selbst ist mit der Abtriebswelle (40) verbunden, die ein an dieser befestigtes Zahnrad (57) trägt und die auch die unteren teilweise mit Gummi überzogenen Bandrollen (38) antreibt.The disc (53) itself is connected to the output shaft (40) which carries a gearwheel (57) attached to it and which also drives the lower belt rollers (38), which are partially covered with rubber.
Das Zahnrad (57) ist mit einem weiteren Zahnrad (58) verbunden, das denselben Durchmesser aufweist und auf der Welle (39) mittels zweier dazwischenliegender kleiner Zahnräder (59, 60) befestigt ist.The gearwheel (57) is connected to a further gearwheel (58) which has the same diameter and is fastened on the shaft (39) by means of two small gearwheels (59, 60) located in between.
Das Zahnrad treibt die oberen Bandrollen (37) an.The gear drives the upper band rollers (37).
Die Vorrichtung sichert den synchronen Antrieb der oberen und unteren Bandrollen, indem es die Einstellung der Druckkraft zwischen den genannten oberen und unteren Bandrollen ermöglicht.The device ensures the synchronous drive of the upper and lower belt rolls by allowing the setting of the pressure force between said upper and lower belt rolls.
Die unteren und oberen teilweise mit Gummi überzogenen Bandrollen (37, 38) sind derart befestigt, daß die mit Gummi überzogenen Teile - die folglich einen größeren Durchmesser haben - genau in Phase sind, d. h., Anfang und Ende der Gummischicht passieren die Verbindungslinie der Mittelpunkte (39, 40), und zwar die der oberen und unteren Bandrollen gleichzeitig, wodurch das sich dazwischen befindliche Exemplar (27) gleichzeitig eingeklemmt bzw. freigegeben wird.The lower and upper partially rubber-coated tape rolls (37, 38) are fastened in such a way that the rubber-coated parts - which consequently have a larger diameter - are exactly in phase, i.e. the beginning and end of the rubber layer pass the connecting line of the center points ( 39, 40), namely that of the upper and lower band rolls at the same time, as a result of which the specimen (27) located between them is clamped or released at the same time.
Wenn R der Rotationsradius der Achse der Kurvenrolle (54) um die Welle (48) und E die Exzentrizität zwischen den zwei Wellen (40, 48) ist, erreicht die Geschwindigkeit der Welle (40) einmal pro Umdrehung ein Maximum von V x R / (R - E) und ein Minimum von V x R / (R + E), wobei V für die Eintrittswinkelgeschwindigkeit der Welle (48) steht.If R is the radius of rotation of the axis of the cam roller (54) around the shaft (48) and E is the eccentricity between the two shafts (40, 48), the speed of the shaft (40) reaches a maximum of V x R / once per revolution (R - E) and a minimum of V x R / (R + E), where V stands for the entry angular velocity of the shaft (48).
Fig. 9 weist ein Diagramm auf, in dem zwei Kurven (70, 71) abgebildet sind.Fig. 9 has a diagram in which two curves (70, 71) are shown.
Auf der Abszisse ist der Rotationswinkel A von -90° bis +360° der Antriebswelle (48) der Vorrichtung von Fig. 8 aufgetragen.The rotation angle A of -90 ° to + 360 ° of the drive shaft (48) of the device of FIG. 8 is plotted on the abscissa.
Auf der Ordinate ist der Rotationswinkel B der Abtriebswelle (40) aufgetragen. Die Kurve (70) stellt den Austrittswinkel in Abhängigkeit von dem Eintrittswinkel dar. Die Kurve (71), die in demselben Diagramm eingezeichnet ist, ist die Ableitung der Kurve (70) und gibt in allen Punkten das Verhältnis zwischen der Austrittswinkelgeschwindigkeit und der Eintrittswinkelgeschwindigkeit in der in Fig. 8 dargestellten Vorrichtung an.The rotation angle B of the output shaft (40) is plotted on the ordinate. The curve (70) represents the exit angle as a function of the entry angle. The curve (71), which is shown in the same diagram, is the derivative of the curve (70) and gives the relationship between the exit angle speed and the entry angle speed in all points of the device shown in FIG.
Die Kurve (71) weist also die Umfangsgeschwindigkeitsänderung der teilweise mit Gummi überzogenen Bandrollen (37, 38) in Abhängigkeit von deren Winkelumdrehung auf.The curve (71) thus shows the change in circumferential speed of the belt rolls (37, 38), which are partially covered with rubber, as a function of their angular rotation.
Die Vorrichtung funktioniert auf folgende Weise: Ein Exemplar (27) wird von den schnellen Bändern (28, 29) zwischen die beiden teilweise mit Gummi überzogenen Bandrollen (37, 38) mit der Geschwindigkeit der schnellen Bänder gestoßen (s. Fig. 9, Gerade 72). Wenn dieses Exemplar die Verbindungslinie der Mittelpunkte (39, 40) einige Zentimeter überschreitet, kommen die teilweise mit Gummi überzogenen Bandrollen (37, 38) bei ihrer Rotationsbewegung an den Punkt, an dem diese mit Gummi überzogen sind und an diesem Punkt erreichen die Bandrollen ihre Höchstgeschwindigkeit.The device works in the following way: A specimen (27) is pushed by the fast belts (28, 29) between the two partly rubber-coated belt rolls (37, 38) at the speed of the fast belts (see FIG. 9, straight line) 72). If this example exceeds the connecting line of the center points (39, 40) by a few centimeters, the partially coated rubber rolls (37, 38) come to the point during their rotational movement, at which these are covered with rubber and at this point the tape rolls reach their top speed.
Die Signatur erreicht also die Geschwindigkeit dieser teilweise mit Gummi überzogenen Bandrollen, die der der schnellen Bändern (Gerade 72) entspricht.The signature thus reaches the speed of these partially rubber-coated tape rolls, which corresponds to that of the fast tapes (straight line 72).
Bei ihrer Rotationsbewegung gehen die teilweise mit Gummi überzogenen Bandrollen (37, 38) und das dazwischengeklemmte Exemplar (27) von einer schnellen Geschwindigkeit (72) zu einer langsamen Geschwindigkeit (73) über (s. durchgezogene Kurve (71) in Fig. 9).During their rotational movement, the partially coated rubber rolls (37, 38) and the specimen (27) clamped between them change from a fast speed (72) to a slow speed (73) (see solid curve (71) in FIG. 9) .
Bei dieser Rotationsbewegung wird das Exemplar (27) an seinem Querfalzrücken zwischen die langsamen Bänder (30, 31) geschoben, die genau mit dieser Geschwindigkeit umlaufen.During this rotational movement, the specimen (27) is pushed on its cross fold back between the slow belts (30, 31), which rotate at precisely this speed.
In dem Moment, in dem der Gummibereich der teilweise mit Gummi überzogenen Bandrollen (37, 38) nicht mehr auf das Exemplar (27) wirkt, wird es von den langsamen Bändern (30, 31) mitgenommen.At the moment when the rubber area of the band rolls (37, 38) partially covered with rubber no longer acts on the specimen (27), the slow belts (30, 31) take it away.
Die Verstellräder (35) auf den schnellen und langsamen Bändern (Fig. 6) haben die Aufgabe, den genauen Punkt einzustellen, an dem die Bänder das Exemplar erfassen bzw. freigeben.The adjusting wheels (35) on the fast and slow belts (Fig. 6) have the task of setting the exact point at which the belts capture or release the copy.
Die Schwenkbarkeit der oberen teilweise mit Gummi überzogenen Bandrolle (37) in bezug auf den Hebel (44) mittels Belastung durch den Zylinder (46) ermöglicht sowohl die Dosierung der Kraft, mit der die Bandrollen das Exemplar (27) erfassen, ungeachtet der Dicke des Exemplars (27), als auch deren Kompensation im Falle eines Papierstaus, bei dem sich die Exemplare zwischen den beiden Bandrollen ansammeln.The pivotability of the upper partially rubber-coated tape roll (37) with respect to the lever (44) by means of the load on the cylinder (46) enables both the metering of the force with which the tape rolls grasp the specimen (27), regardless of the thickness of the Copy (27), as well as their compensation in the event of a paper jam, in which the copies accumulate between the two rolls of tape.
Fig. 10 weist einen erfindungsgemäßen Falzapparat auf, der aus zwei getrennten Bänderanordnungen besteht, die den Verlangsamungszylindern nachgeordnet sind. Dieser Falzapparat eignet sich sowohl für die Bildung eines oberen Schwertfalzes als auch eines unteren Schwertfalzes.Fig. 10 has a folder according to the invention, which consists of two separate belt arrangements, the slowdown cylinders are subordinate. This folder is suitable for the formation of an upper sword fold as well as a lower sword fold.
Vorstellbar ist auch ein Ausführungsbeispiel, bei dem sowohl auf den oberen als auch auf den unteren Verlangsamungszylinder verzichtet wird.An embodiment is also conceivable in which both the upper and the lower deceleration cylinders are dispensed with.
Ein solcher Falzapparat ist in Fig. 11 abgebildet. Das Exemplar (27) wird also dem Falzklappenzylinder (5) von den schnellen Bänderanordnungen direkt entnommen.Such a folder is shown in Fig. 11. The specimen (27) is therefore taken directly from the folding jaw cylinder (5) by the fast belt arrangements.
Die Exzentrizität zwischen den Wellen (40, 48) sowie der Rotationsradius der Achse der Kurvenrolle (54) um die Welle (48) werden somit verstellt, um eine Geschwindigkeitsreduzierung der teilweise mit Gummi überzogenen Bandrollen um 50% zu erreichen.The eccentricity between the shafts (40, 48) and the radius of rotation of the axis of the cam roller (54) around the shaft (48) are thus adjusted in order to reduce the speed of the partially coated rubber rollers by 50%.
Außerdem drehen sich die langsamen Bänder halb so schnell wie die schnellen Bänder.In addition, the slow belts rotate half as fast as the fast belts.
Erfindungsgemäß ist auch eine Vorrichtung denkbar, mit der Falzexemplare eines variablen Falzapparates - so wie er im Tiefdruck verwendet wird - oder einer völlig anderen Art von Falzapparat verlangsamt werden.According to the invention, a device is also conceivable with which folding copies of a variable folding apparatus - as used in gravure printing - or a completely different type of folding apparatus are slowed down.
Die oben beschriebene Vorrichtung kann auch benutzt werden, um eine zyklische Geschwindigkeitsänderung (Kurbelzapfen, der eine mit einem Schlitz versehene Scheibe antreibt) zu erreichen und könnte durch eine völlig andere Vorrichtung ersetzt werden, z. B.:
- durch eine Indexvorrichtung
- oder durch ein Kardangelenk mit folgenden Gleichungen: Maximalgeschwindigkeit = Eintrittsgeschwindigkeit/cos α Minimalgeschwindigkeit = Eintrittsgeschwindigkeit x cos α In diesem Gleichungen ist die Eintrittsgeschwindigkeit eines einzigen Kardangelenkes, das zwischen Antriebs- und Abtriebswelle einen Winkel α beschreibt, variabel.
- durch ein Gleichlaufgelenk, z. B. ein dreigliedriges Gelenk, das am Ende einer schräg gelagerten Welle vorgesehen und mit einem Kardangelenk verbunden wird, wobei zwei parallel angeordnete Wellen verbunden werden und die Austrittsgeschwindigkeit nicht-linear machen.
- through an indexing device
- or by means of a universal joint with the following equations: maximum speed = entry speed / cos α minimum speed = entry speed x cos α In this equation, the entry speed of a single universal joint, which describes an angle α between the input and output shafts, is variable.
- through a constant velocity joint, e.g. B. a three-part joint, which is provided at the end of an inclined shaft and connected to a universal joint, two parallel shafts being connected and making the exit speed non-linear.
Zum Herbeiführen einer nicht-linearen Geschwindigkeit könnten auch andere Vorrichtungen verwendet werden, z. B. Vorrichtungen mit zwei Kurbelzapfen, die über eine Stange etc. miteinander verbunden sind.Other devices could also be used to achieve non-linear velocity, e.g. B. Devices with two crank pins, which are connected together via a rod, etc.
