Definitions
- the invention relates to a device for reducing the impact speed of printed products in the base of a delivery paddle wheel of printing machines according to the preamble of claim 1.
- cam disks are arranged on double-lever-like arms rotatably mounted about the bucket wheel axis, in each case between the bucket wheel disks.
- rings are attached to a rotatable shaft.
- This shaft is mounted in a frame enclosing the extension impeller which, together with the double-lever arms, can be adjusted about the axis of the extension impeller by means of an adjusting device.
- This adjustment is used to ensure that when converting production to a product with a different format, which has an impact on the delivery paddle wheel in the form of different product lengths, the product is detected and braked at the trailing end and before it hits the blade base.
- it is necessary to additionally adjust the cam disks in the new position. This additional adjustment of the cam discs makes adjustment in the course of the machine and automation of the adjustment more difficult.
- the object of the invention is to provide a device for reducing the impact speed of printed products in the base of a delivery paddle wheel, which allows easy adjustment even with the machine running to different format lengths of the printed products, and in which the position of the cam disks with respect to the printed products for each Position is optimal.
- the position of the leading edge with respect to the delivery paddle wheel is always the same, regardless of the length of the printed product. It is achieved with the device according to the invention that when the position of the cam disks is adjusted, which must be aligned with the trailing end of the printed product, which depends on the length of the printed product, the position of the cams with respect to the printed products always remains optimal. Starting from a set position of the cam disks, in which one of the cams is directed against the axis of the extension bucket wheel, when the position of the cam disks is adjusted when the machine is at a standstill, this cam is always directed against the axis of the extension bucket wheel. This is achieved by the practical correspondence of the ratios of the effective length of the lever to the effective length of the swivel lever and the ratio i (drive elements to camshaft shaft) to i-1.
- lever lengths and drive ratio exist with a ratio in the order of two. This does not result in an excessively large swivel angle for the levers and the drive elements also have no oversized dimensions.
- the longitudinal guide for the pivoting lever is advantageously arranged on the connecting straight line between the axis of the extension bucket wheel and the cam disk shaft when the cam disks are in the middle of their adjustment range.
- the longitudinal guides for the pivot of the pivot lever are also arranged so that the pivot moves in the straight line mentioned. A symmetrical behavior is thus achieved for the setting both for the printed products with the shortest length and for the printed products with the greatest length.
- a further advantageous embodiment of the device is that the levers arranged on both sides of the extension impeller are extended beyond the extension impeller with respect to the cam disks and are connected to one another by a web. Also connected to this web are the roller levers bearing the roller, which are pivotably mounted on the axle between the disk-shaped blade portions of the extension blade wheel, and their rollers, which, in cooperation with the cam disks, form the printed product brake, their position with respect to the cam disks even when adjusted maintained.
- the delivery paddle wheel 1 can be rotated about the axis 2 according to FIGS. 1 to 3 and is driven in the direction of the arrow 3.
- the vanes 4 are attached, which form pockets 5, into which the printed products 6 delivered by the folder are inserted, in order then to be laid out in the form of a scale.
- the levers 7 are pivotally mounted on both sides of the extension bucket wheel 1 about the axis 2.
- a shaft 8, on which the cam disks 9 are seated, is rotatably mounted in the levers 7.
- Each cam disk 9 is equipped with cams 10.
- the shaft 8 is equipped with a toothed belt wheel 11, which is driven via a toothed belt 12 in the direction of arrow 21.
- a pivot lever 13 is hinged at one end 14.
- a pin 16 On this pin 16, a drive element 17, designed as a toothed belt wheel, is rotatably mounted, which the Timing belt 12 drives.
- the pin 16 is guided by longitudinal guides 18 (FIG. 4), which allow the pin 16 to move back and forth in the radial direction to the delivery paddle wheel 1.
- the toothed belt wheel 17 is connected via a coupling 19 (FIG. 4) to a drive device 20 fixed to the machine frame.
- the drive device 20 is coupled to the machine drive in a known manner.
- the cam disks 9 interact with rollers 22.
- the rollers 22 are arranged between the disk-shaped blade parts 23 (FIG. 4) and are each set in rotation individually via a drive 24.
- the printed products 6 arrive in time with the delivery paddle wheel 1 in the pockets 5 formed by the blades 4. The time at which the printed product 6 dips into the pocket 5 always remains the same for the front edge 25 of the printed product 6, regardless of its length .
- the printed products 6 entering the delivery impeller 1 at high speed are briefly held between the cam disc 9 and the roller 22 by the arriving cam 10 at their trailing end 26, braked, released by the cam 10 and reach the bottom 27 at a reduced speed immediately after being released the pocket 5, where they are braked to the final speed at which the delivery paddle wheel 1 is driven. Since the last speed difference is only small, the printed products 6 reach the bottom 27 of the pocket 5 without being damaged and without rebounding, which then enables a perfect scale delivery.
- Fig. 1 shows the position of the cam disks 9 for a printed product 6 of medium length.
- Fig. 2 the position of the cam disks 9 for a printed product 6 with the smallest length is shown, with the same position of the delivery impeller 1 as in Fig. 1.
- the cam disks 9 with the associated rollers 22 are pivoted into the position shown.
- the design according to the invention ensures that the cams 10 remain in the optimal position with respect to the trailing end 26 of the short printed product 6.
- the pin 16 is displaced along the longitudinal guides 18 in the radial direction to the extension impeller 1.
- the cam disks 9 are rotated back somewhat by the selected dimensions, i.e.
- the cam 10 shown in engagement always points against the axis 2 of the extension bucket wheel.
- the axis 2 of the extension bucket wheel 1 is held in the bearing 29.
- a schematically illustrated drive 30 sets the delivery paddle wheel 1 in rotation.
- the levers 7 are arranged pivotably about the axis 2 on both sides of the extension bucket wheel 1; only one side is shown in FIG. 4.
- the shaft 8 is held in the lever 7 by bearings 31.
- the pivot lever 13 is seated with its one end 14 on a bearing bush 32 and is pivotable. Its other end 15 is provided with the pin 16 which, on the one hand, is guided in the longitudinal guides 18, which are fastened to the side wall 28 with a bracket 33, and on the other hand carries the timing wheel 17, which is freely rotatable.
- the clutch 19 connects the toothed belt wheel 17 with the machine frame-fixed drive device 20.
- the coupling 19 can transmit rotary movements of offset shafts synchronously.
- the levers 7 are extended on the side opposite the shaft 8 beyond the extension paddle wheel 1.
- a web 34 connects the two levers 7.
- the roller levers 35 which carry the rollers 22 and are also pivotable about the axis 2, are fastened between the disk-shaped blade portions 23, 23 '.
- cam disks 9 and rollers 22 form a unit, regardless of the position they occupy.
- Each of the rollers 22 is driven separately by a drive unit 36, coordinated with the rotation of the cam disks 9.
- the pivoting of the levers 7 about the axis 2 of the delivery bucket wheel is carried out by known means, not shown, which can be actuated both automatically and by hand.
- the swiveling can take place while the machine is running or at a standstill.

Description
Die Erfindung betrifft eine Vorrichtung zur Verminderung der Aufprallgeschwindigkeit von Druckprodukten im Grund eines Auslegeschaufelrades von Druckmaschinen nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for reducing the impact speed of printed products in the base of a delivery paddle wheel of printing machines according to the preamble of
Eine derartige Vorrichtung ist aus der DE-A-34 06 069 bekannt. Hierbei sind Nockenscheiben auf um die Schaufelradachse drehbar gelagerten doppelhebelartigen Armen jeweils zwischen den Schaufelradscheiben angeordnet. In Wirkverbindung mit den Nockenscheiben sind Ringe auf einer drehbaren Welle angebracht. Diese Welle ist in einem das Auslegeschaufelrad umschliessenden Rahmen gelagert, der zusammen mit den doppelhebelartigen Armen um die Auslegeschaufelradachse über eine Stelleinrichtung verstellbar ist. Diese Verstellung dient dazu, bei einer Umstellung der Produktion auf ein Produkt mit einem anderen Format, was sich im Auslegeschaufelrad in Form von unterschiedlichen Produktlängen auswirkt, zu gewährleisten, das Produkt am nachlaufenden Ende und vor dem Auftreffen im Schaufelgrund zu erfassen und abzubremsen. Mit der in dieser Vorrichtung angewandten Antriebskonfiguration ist es erforderlich, die Nockenscheiben in der neuen Lage zusätzlich einzujustieren. Dieses zusätzliche Einjustieren der Nockenscheiben erschwert eine Verstellung im Lauf der Maschine und eine Automatisierung der Verstellung.Such a device is known from DE-A-34 06 069. Here, cam disks are arranged on double-lever-like arms rotatably mounted about the bucket wheel axis, in each case between the bucket wheel disks. In operative connection with the cam discs, rings are attached to a rotatable shaft. This shaft is mounted in a frame enclosing the extension impeller which, together with the double-lever arms, can be adjusted about the axis of the extension impeller by means of an adjusting device. This adjustment is used to ensure that when converting production to a product with a different format, which has an impact on the delivery paddle wheel in the form of different product lengths, the product is detected and braked at the trailing end and before it hits the blade base. With the drive configuration used in this device, it is necessary to additionally adjust the cam disks in the new position. This additional adjustment of the cam discs makes adjustment in the course of the machine and automation of the adjustment more difficult.
Die Aufgabe der Erfindung besteht nun darin, eine Vorrichtung zur Verminderung der Aufprallgeschwindigkeit von Druckprodukten im Grund eines Auslegeschaufelrades zu schaffen, die ein einfaches Verstellen auch bei laufender Maschine auf unterschiedliche Formatlängen der Druckprodukte ermöglicht, und bei der die Lage der Nockenscheiben bezüglich der Druckprodukte für jede Stellung optimal ist.The object of the invention is to provide a device for reducing the impact speed of printed products in the base of a delivery paddle wheel, which allows easy adjustment even with the machine running to different format lengths of the printed products, and in which the position of the cam disks with respect to the printed products for each Position is optimal.
Die Aufgabe ist erfindungsgemäss durch die Merkmale des Anspruchs 1 gelöst.According to the invention, the object is achieved by the features of
Bei dem vom Falzapparat ins Auslegeschaufelrad angelieferten Druckprodukte ist die Lage der vorlaufenden Kante bezüglich des Auslegeschaufelrades unabhängig von der Druckproduktelänge immer gleich. Mit der erfindungsgemässen Vorrichtung wird erreicht, dass bei der Einstellung der Lage der Nockenscheiben, die ja auf das nachlaufende Ende des Druckproduktes, das von der Länge des Druckproduktes abhängt, ausgerichtet sein müssen, die Stellung der Nocken bezüglich der Druckprodukte immer optimal bleibt. Ausgehend von einer eingestellten Lage der Nockenscheiben, in welcher eine der Nocken gegen die Achse des Auslegeschaufelrades gerichtet ist, ist bei Verstellung der Lage der Nockenscheiben bei stillstehender Maschine diese Nocke immer gegen die Achse des Auslegeschaufelrades gerichtet. Dies wird durch die praktische Uebereinstimmung der Verhältnisse von Wirklänge des Hebels zur Wirklänge des Schwenkhebels und von Uebersetzung i (Antriebselements zu Nockenscheibenwelle) zu i-1 erfüllt.In the case of the printed products delivered by the folder into the delivery paddle wheel, the position of the leading edge with respect to the delivery paddle wheel is always the same, regardless of the length of the printed product. It is achieved with the device according to the invention that when the position of the cam disks is adjusted, which must be aligned with the trailing end of the printed product, which depends on the length of the printed product, the position of the cams with respect to the printed products always remains optimal. Starting from a set position of the cam disks, in which one of the cams is directed against the axis of the extension bucket wheel, when the position of the cam disks is adjusted when the machine is at a standstill, this cam is always directed against the axis of the extension bucket wheel. This is achieved by the practical correspondence of the ratios of the effective length of the lever to the effective length of the swivel lever and the ratio i (drive elements to camshaft shaft) to i-1.
Vorteilhafte Abmessungen für Hebellängen und Antriebsübersetzung bestehen bei einer Verhältniszahl in der Grössenordnung von zwei. Hierbei entstehen keine übermässig grossen Schwenkwinkel für die Hebel und auch die Antriebselemente weisen keine überdimensionale Abmessungen auf.Advantageous dimensions for lever lengths and drive ratio exist with a ratio in the order of two. This does not result in an excessively large swivel angle for the levers and the drive elements also have no oversized dimensions.
In vorteilhafter Weise wird die Längsführung für den Schwenkhebel auf der Verbindungsgeraden zwischen der Achse des Auslegeschaufelrades und der Nockenscheibenwelle angeordnet, wenn sich die Nockenscheiben in der Mitte ihres Verstellbereiches befinden. Auch die Längsführungen für den Zapfen des Schwenkhebels sind so angeordnet, dass sich der Zapfen in der genannten Geraden bewegt. Damit wird ein symmetrisches Verhalten erreicht für die Einstellung sowohl für die Druckprodukte mit geringster Länge als auch für Druckprodukte mit grösster Länge.The longitudinal guide for the pivoting lever is advantageously arranged on the connecting straight line between the axis of the extension bucket wheel and the cam disk shaft when the cam disks are in the middle of their adjustment range. The longitudinal guides for the pivot of the pivot lever are also arranged so that the pivot moves in the straight line mentioned. A symmetrical behavior is thus achieved for the setting both for the printed products with the shortest length and for the printed products with the greatest length.
Eine weitere vorteilhafte Gestaltung der Vorrichtung besteht darin, dass die beidseits des Auslegeschaufelrads angeordneten Hebel gegenüber der Nockenscheiben über das Auslegeschaufelrad hinaus verlängert und mit einem Steg miteinander verbunden sind. Ebenfalls mit diesem Steg verbunden werden können die die Rolle tragenden Rollenhebel, die zwischen den scheibenförmigen Schaufelpartien des Auslegeschaufelrades auf dessen Achse schwenkbar gelagert sind, und deren Rollen, die in Zusammenarbeit mit den Nockenscheiben die Druckproduktebremse bilden, gegenüber den Nockenscheiben ihre Lage auch bei einer Verstellung beibehalten.A further advantageous embodiment of the device is that the levers arranged on both sides of the extension impeller are extended beyond the extension impeller with respect to the cam disks and are connected to one another by a web. Also connected to this web are the roller levers bearing the roller, which are pivotably mounted on the axle between the disk-shaped blade portions of the extension blade wheel, and their rollers, which, in cooperation with the cam disks, form the printed product brake, their position with respect to the cam disks even when adjusted maintained.

Das Auslegeschaufelrad 1 ist nach den Fig. 1 bis Fig. 3 um Achse 2 drehbar und wird in Richtung des Pfeils 3 angetrieben. Am Umfang des Auslegeschaufelrades 1 sind die Schaufeln 4 angebracht, die Taschen 5 bilden, in welche die vom Falzapparat angelieferten Druckprodukte 6 eingesteckt werden, um dann in Schuppenform ausgelegt zu werden.The
Um die Achse 2 sind die Hebel 7 beidseits des Auslegeschaufelrades 1 schwenkbar gelagert. Eine Welle 8, auf welcher die Nockenscheiben 9 sitzen, ist in den Hebeln 7 drehbar gelagert. Jede Nockenscheibe 9 ist mit Nocken 10 ausgerüstet. Die Welle 8 ist mit einem Zahnriemenrad 11 ausgerüstet, welches über einen Zahnriemen 12 in Richtung des Pfeils 21 angetrieben ist. An die Welle 8 ist ein Schwenkhebel 13 mit einem Ende 14 angelenkt. Im anderen Ende 15 steckt ein Zapfen 16. Auf diesem Zapfen 16 ist ein Antriebselement 17, als Zahnriemenrad ausgebildet, drehbar gelagert, das den Zahnriemen 12 antreibt. Der Zapfen 16 ist durch Längsführungen 18 (Fig. 4) geführt, welche erlauben, dass sich der Zapfen 16 in radialer Richtung zum Auslegeschaufelrad 1 hin und her bewegen kann. Das Zahnriemenrad 17 ist über eine Kupplung 19 (Fig. 4) mit einer maschinengestellfesten Antriebseinrichtung 20 verbunden. Die Antriebseinrichtung 20 ist in bekannter Weise an den Maschinenantrieb gekoppelt.The
Die Nockenscheiben 9 wirken mit Rollen 22 zusammen. Die Rollen 22 sind zwischen den scheibenförmigen Schaufelpartien 23 (Fig. 4) angeordnet und werden jede einzeln über einen Antrieb 24 in Drehung versetzt.The
Die Druckprodukte 6 gelangen im Takt mit dem Auslegeschaufelrad 1 in die von den Schaufeln 4 gebildeten Taschen 5. Der Zeitpunkt, bei welchem das Druckprodukt 6 in die Tasche 5 eintaucht, bleibt für die Vorderkante 25 des Druckprodukts 6, unabhängig von dessen Länge, immer gleich. Die mit grosser Geschwindigkeit in das Auslegeschaufelrad 1 einfahrenden Druckprodukte 6 werden zwischen Nockenscheibe 9 und Rolle 22 durch den eintreffenden Nocken 10 an ihrem nachlaufenden Ende 26 kurzzeitig festgehalten, abgebremst, vom Nocken 10 wieder losgelassen und erreichen unmittelbar nach dem Loslassen mit reduzierter Geschwindigkeit den Grund 27 der Tasche 5, wo sie auf die endgültige Geschwindigkeit, mit welcher das Auslegeschaufelrad 1 angetrieben ist, abgebremst werden. Da die letzte Geschwindigkeitsdifferenz nur noch klein ist, erreichen die Druckprodukte 6 den Grund 27 der Tasche 5 ohne Schaden zu nehmen und ohne Zurückprallen, was dann eine perfekte Schuppenauslage ermöglicht.The printed
Fig. 1 zeigt die Lage der Nockenscheiben 9 für ein Druckprodukt 6 mittlerer Länge.Fig. 1 shows the position of the
In Fig. 2 ist, bei gleicher Lage des Auslegeschaufelrades 1 wie in Fig. 1, die Stellung der Nockenscheiben 9 für ein Druckprodukt 6 mit kleinster Länge dargestellt. Um ein optimales Abbremsen des Druckproduktes 6 zu gewährleisten, werden die Nockenscheiben 9 mit den zugehörigen Rollen 22 in die dargestellte Lage geschwenkt. Durch die erfindungsgemässe Gestaltung wird erreicht, dass die Nocken 10 in der optimalen Lage bezüglich des nachlaufenden Endes 26 des kurzen Druckprodukts 6 bleiben. Bei dieser Einstellung erfolgt ein Verschieben des Zapfens 16 entlang der Längsführungen 18 in radialer Richtung zum Auslegeschaufelrad 1. Durch die gewählten Abmessungen werden die Nockenscheiben 9 etwas zurückgedreht, d.h. der im Eingriff dargestellte Nokken 10 zeigt immer gegen die Achse 2 des Auslegeschaufelrades.In Fig. 2, the position of the
In Fig. 3 ist wiederum bei derselben Lage des Auslegeschaufelrades 1 die Stellung der Nockenscheiben 9 für ein Druckprodukt 6 mit grösster Länge aufgezeigt. Wegen der Symmetrie zur Mittelstellung ist das Verhalten genau umgekehrt zur in Fig. 2 dargestellten Situation.3 again shows the position of the
In der Seitenwand 28, ersichtlich in Fig. 4, ist die Achse 2 des Auslegeschaufelrades 1 im Lager 29 gehalten. Ein schematisch dargestellter Antrieb 30 versetzt das Auslegeschaufelrad 1 in Drehung. Beidseits des Auslegeschaufelrades 1 sind die Hebel 7 schwenkbar um die Achse 2 angeordnet, in Fig. 4 ist nur eine Seite dargestellt. Die Welle 8 ist durch Lager 31 im Hebel 7 gehalten. Der Schwenkhebel 13 sitzt mit seinem einen Ende 14 auf einer Lagerbüchse 32 und ist schwenkbar. Sein anderes Ende 15 ist mit dem Zapfen 16 versehen, der einerseits in den Längsführungen 18, die mit einem Bügel 33 an der Seitenwand 28 befestigt sind, geführt ist, andererseits das Zahriemenrad 17, das frei drehbar ist, trägt. Die Kupplung 19 verbindet das Zahnriemenrad 17 mit der maschinengestellfesten Antriebseinrichtung 20. Die Kupplung 19 kann Drehbewegungen von versetzten Wellen synchron übertragen.In the
Die Hebel 7 sind an der der Welle 8 gegenüberliegenden Seite über das Auslegeschaufelrad 1 hinaus verlängert. Ein Steg 34 verbindet die beiden Hebel 7. An diesem Steg 34 sind zwischen den scheibenförmigen Schaufelpartien 23, 23′ die Rollenhebel 35 befestigt, die die Rollen 22 tragen und ebenfalls um die Achse 2 schwenkbar sind. Dadurch bilden Nockenscheiben 9 und Rollen 22 eine Einheit, unabhängig von der Stellung, die sie einnehmen. Jede der Rollen 22 ist separat durch eine Antriebseinheit 36 angetrieben, abgestimmt auf die Drehung der Nockenscheiben 9.The
Die Schwenkung der Hebel 7 um die Achse 2 des Auslegeschaufelrades erfolgt durch nicht dargestellte, bekannte Mittel, welche sowohl automatisch als auch von Hand betätigbar sind. Die Schwenkung kann bei laufender Maschine oder bei Stillstand erfolgen.The pivoting of the
