Definitions
- the invention relates to a sheet delivery device, in particular for small offset printing presses, with a stripping device which removes a printed sheet from a printing cylinder, a pair of supporting elements which are displaceably and lockably mounted on a cross member extending transversely to the sheet running direction, a pair of guide and Transport roller assemblies, each having a guide roller that holds the trailing end of the sheet on the impression cylinder, a freely rotatable first transport roller that rolls on the top of the detached sheet, and a second transport roller that rolls on the underside of the detached sheet, a drive shaft common to the second transport rollers, on which the second transport rollers are mounted so as to be longitudinally displaceable and with a guide device for the sheet leaving the transport rollers and carried by the carrying elements.
- Such sheet delivery devices are used in small offset machines, but also in at least a similar design in devices or devices for copying, duplicating or printing for office or other commercial purposes.
- the sheet delivery device or various of its components mentioned in the generic term must be adjustable with respect to one another, or must be adjustable overall. These necessities result, for example, from the different format widths and thicknesses of the sheets.
- a sheet delivery device is known from US-PS-305 838.
- the guide and transport roller arrangements which can be adjusted to the format width of a printed sheet by means of a pair of support elements (29 '), can be pivoted about a common axis by means of a pair of pivoting arms (26) and lack the possibility of individually adjusting the contact pressure of the guide roller and the like upper transport roller.
- the sheet guiding devices assigned to the transport rollers are pivotably arranged together with the transport rollers. There is no evidence of an adjustment of these sheet guiding devices to the format width.
- a sheet guide device is not provided here.
- a sheet delivery device known from DE-OS-2 045 148 essentially differs from this in that the upper transport rollers (26, 27) are pressed exclusively under the force of gravity against a transport roller (6) which takes over the function of lower transport rollers.
- the object of the present invention is to provide a sheet delivery device, in particular for small offset presses, which enables simple and problem-free handling with regard to setting the format width and the respective contact pressure of the rolls used and also ensures gentle handling of the sheets to be laid out.
- This sheet delivery device is characterized above all by an extremely compact and clear construction. A major advantage is ultimately that all setting and adjustment work can be carried out even when the machine is in operation.
- a sheet 5 to be printed is separated from the stack 1 and fed to a printing cylinder 3 via a feed device 2.
- the transfer of the printed image takes place in the gap between the latter and a rubber cylinder 4.
- the printed sheet 5 is then taken over by a sheet delivery device 6 and fed to a delivery stack 7.
- the rubber cylinder 4 receives the print image from a plate cylinder 8 in front of it, which receives the printing ink via an application roller 9 which is in contact with an inking and dampening unit 10, 11.
- the machine receives the corresponding commands from the machine operator via the control panel 12.
- Blanket washing device 61, film drawing and etching device 62, 63 are further essential components of the machine.
- a stripper 13 is provided which, after its release by the sheet gripper 14, releases the sheet 5 from the printing cylinder 3 and supplies downstream transport rollers 21, 22.
- the stripper 13, which consists of a plurality of stripper fingers 15 distributed over the machine width in a corresponding arrangement, is fastened to the side walls 17, 18 of the machine with fastening rails 19 carrying these stripper fingers 15 (FIG. 3).
- the rear area of the sheet 5 is held in contact with the printing cylinder 3 by means of a guide roller 20 which bears against the printing cylinder 3 until it has been taken over by the transport rollers 21, 22.
- the latter are in the form of cylindrical rubber rollers 21 assigned to the left and right side of the sheet, as seen over the width of the sheet, and pressure rollers 22 attached to them with a certain contact pressure.
- the contact pressure can be set via a device to be described in more detail later.
- the transport rollers 21, 22, that is to say in particular the cylindrical rubber roller 21, is further followed by a respective guide plate 23 arranged on the left and right sides, which is shaped in such a way that the sheet 5 to be laid out is given a slight curvature so that its internal stability is increased by make his way to the delivery pile 7 more trouble-free.
- Guide roller 20 and pressure roller 22 are mounted on a support element 24 designed as an elongated bearing block, which is displaceable in the axial direction on a flattened round axis 25 and can be fixed by means of a toggle screw 26.
- the flattened rotary axis 25 is fastened to the side walls 17, 18 of the machine by fastening screws 27.
- the support element 24 is supported with its fork-shaped projection 28 on a further axis 29, which is also supported by means of fastening screws 27 on the two side walls 17, 18.
- Each guide roller 20 is also rotatably mounted on a lever 31, which in turn can be pivoted about a bearing pin 32 of the support element 24 and is spring-supported on the latter via compression spring 33, guide pin 34 and nut 35 with the associated lock nut 30, in order thereby to be able to be applied with a preselectable pressing force on To apply pressure cylinder 3.
- the pressure roller 22 is also mounted on the support element 24 by means of an axle pin 36 and a lever 37, the other end of which is connected to the support element 24 by means of a bearing pin 38. Via a bolt 40 guided in a bore 39 of the supporting element 24, on which a compression spring 41 acts, the contact pressure is transmitted to the contact roller 22 via a further lever 60 connected to the bearing journal 38.
- the contact pressure can be varied by means of an adjusting screw 42 acting on the compression spring 41 with a predetermined adjustment range.
- the setting range includes, for example, less than one screw revolution.
- a protective shield 44 is provided between the toggle screw 26 and the adjusting screw 42 and the area of the sheet delivery device 6 facing the pressure cylinder 3. This maintains the free accessibility of the aforementioned adjustment elements.
- Rubber roller 21 and guide plate 23 are connected to the support element 24 via a bracket 45. They are thus laterally adjusted simultaneously with the pressure roller 22. Baffle 23 and rubber roller 21 can also be adjusted laterally relative to the pressure roller 22 by means of knurled nuts 46, which act on a tab 43 of the bracket 45. As can be seen from FIG. 4, the knurled nuts 46 are screwed onto a threaded pin 47 which engages in a threaded bore 48 of the support element 24.
- the bracket 45 is detachably attached to the lower flattened side 49 of the support element 24 and correspondingly laterally displaceable and continues to encompass the rubber roller 21.
- the latter with a slight sliding fit, is mounted on a drive shaft 50 equipped with a longitudinal groove 57 and can be axially displaced slightly due to the driving connection with the bracket 45.
- the drive shaft 50 is supported by ball bearings 51 in axle brackets 52, which are each fastened to the two side walls 17, 18 by means of fastening screws 53.
- a gear 54 which is mounted on the drive shaft 50 in a rotationally fixed manner, transmits the rotary movement via further gear wheels 55, 56 of the drive chain.

Abstract
Description
Die Erfindung betrifft eine Bogenauslagevorrichtung, insbesondere für Kleinoffsetdruckmaschinen, mit einer einen bedruckten Bogen von einem Druckzylinder ablösenden Abstreifeinrichtung, einem Paar von verschieblich und arretierbar auf einer sich quer zur Bogenlaufrichtung erstreckenden Traverse gelagerten Tragelementen, einem Paar von jeweils gemeinsam mit den Tragelementen verschieblichen Führungs- und Transportrollenanordnungen, welche jeweils eine das nachlaufende Ende des Bogens auf dem Druckzylinder niederhaltende Führungsrolle, eine auf der Oberseite des abgelösten Bogens abrollende frei drehbare erste Transportrolle und eine auf der Unterseite des abgelösten Bogens abrollende zweite Transportrolle aufweist, einer den zweiten Transportrollen gemeinsamen Antriebswelle, auf welcher die zweiten Transportrollen längsverschieblich gelagert sind sowie mit einer von den Tragelementen getragenen Leiteinrichtung für den die Transportrollen verlassenden Bogen.The invention relates to a sheet delivery device, in particular for small offset printing presses, with a stripping device which removes a printed sheet from a printing cylinder, a pair of supporting elements which are displaceably and lockably mounted on a cross member extending transversely to the sheet running direction, a pair of guide and Transport roller assemblies, each having a guide roller that holds the trailing end of the sheet on the impression cylinder, a freely rotatable first transport roller that rolls on the top of the detached sheet, and a second transport roller that rolls on the underside of the detached sheet, a drive shaft common to the second transport rollers, on which the second transport rollers are mounted so as to be longitudinally displaceable and with a guide device for the sheet leaving the transport rollers and carried by the carrying elements.
Derartige Bogenauslagevorrichtungen sind in Kleinoffsetmaschinen, aber auch in zumindest ähnlicher Ausführung in Geräten oder Vorrichtungen zum Kopieren, Vervielfältigen oder Drucken für Büro- oder andere gewerbliche Zwecke in Gebrauch.Such sheet delivery devices are used in small offset machines, but also in at least a similar design in devices or devices for copying, duplicating or printing for office or other commercial purposes.
Für die ordnungsgemäße und störungsfreie Papierbogenauslage ist es erforderlich, daß die Bogenauslagevorrichtung beziehungsweise verschiedene ihrer im Gattungsbegriff genannten Bauteile zueinander einstellbar, bzw. insgesamt verstellbar sein müssen. Diese Notwendigkeiten ergeben sich beispielsweise aufgrund unterschiedlicher Formatbreiten und -dicken der Bogen.For the proper and trouble-free paper sheet delivery, it is necessary that the sheet delivery device or various of its components mentioned in the generic term must be adjustable with respect to one another, or must be adjustable overall. These necessities result, for example, from the different format widths and thicknesses of the sheets.
Eine Bogenauslagevorrichtung gemäß dem Gattungsbegriff ist aus der US-PS-305 838 bekannt. Hierin sind jedoch die mittels eines Paares von Tragelementen (29') auf die Formatbreite eines bedruckten Bogens einstellbaren Führungs- und Transportrollenanordnungen mittels eines Paares von Schwenkarmen (26) um eine gemeinsame Achse schwenkbar und entbehren einer Möglichkeit zur individuellen Einstellung des Anstelldruckes der Führungsrolle und der oberen Transportrolle. Die den Transportrollen zugeordneten Bogenleiteinrichtungen sind in einem Ausführungsbeispiel der US-PS-305 838 gemeinsam mit den Transportrollen schwenkbar angeordnet. Hinweise auf eine Einstellung dieser Bogenleiteinrichtungen auf die Formatbreite sind hieraus nicht entnehmbar.A sheet delivery device according to the generic term is known from US-PS-305 838. Here, however, the guide and transport roller arrangements, which can be adjusted to the format width of a printed sheet by means of a pair of support elements (29 '), can be pivoted about a common axis by means of a pair of pivoting arms (26) and lack the possibility of individually adjusting the contact pressure of the guide roller and the like upper transport roller. In one embodiment of US Pat. No. 305,838, the sheet guiding devices assigned to the transport rollers are pivotably arranged together with the transport rollers. There is no evidence of an adjustment of these sheet guiding devices to the format width.
Bei einer anderen bekannten Bogenauslagevorrichtung gemäß US-PS-2 531 253 steht den mittels eines Paares von Tragelementen auf die Formatbreite einstellbaren oberen Transportrollen (17) eine sich im wesentlichen über die Breite der Druckmaschine erstreckende Tranportwalze (13) gegenüber. Damit ist eine gemeinsame Einstellung von unteren und oberen Transportrollen auf die Formatbreite des bedruckten Bogens nicht möglich. Ebensowenig möglich ist hierbei eine individuelle Einstellung der Andruckkräfte der Führungsrollen und der oberen Transportrollen, da die Führungsrollen (23) auf einer gemeinsamen Achse (19) gelagert sind, welche mittels eines mit einer ersten Feder (21) belasteten Hebels (20) gegen den Druckzylinder (16) angestellt ist und da die Tragelemente ihrerseits mit ihrem einen Ende an derselben Achse (19) angelenkt sind und die am anderen Ende der Tragelemente in den Tragelementen aufgenommenen oberen Führungsrollen über jeweils eine weitere am jeweiligen Tragelement angreifende Feder (34) gegen die Transportwalze (13) gedrückt werden. Dadurch ergibt sich nämlich eine Rückwirkung auf die Andruckkraft der Führungsrollen bzw. der oberen Transportrollen bei einer Änderung einer zur Einstellung der Andruckkraft der jeweils anderen Rollen vorgesehenen Einstellfeder.In another known sheet delivery device according to US Pat. No. 2,531,253, the upper transport rollers (17), which can be adjusted to the format width by means of a pair of support elements, are opposed by a transport roller (13) which extends essentially over the width of the printing press. This means that it is not possible to jointly adjust the lower and upper transport rollers to the format width of the printed sheet. An individual adjustment of the pressure forces of the guide rollers and the upper transport rollers is also not possible, since the guide rollers (23) are mounted on a common axis (19) which is pressed against the pressure cylinder by means of a lever (20) loaded with a first spring (21) (16) is employed and since the support elements are in turn articulated at one end to the same axis (19) and the upper guide rollers accommodated in the support elements at the other end of the support elements via a further spring (34) acting on the respective support element against the transport roller (13) can be pressed. This results in a reaction on the pressing force of the guide rollers or the upper transport rollers when a setting spring provided for adjusting the pressing force of the other rollers is changed.
Eine Bogenleiteinrichtung ist hierbei nicht vorgesehen.A sheet guide device is not provided here.
Eine aus der DE-OS-2 045 148 bekannte Bogenauslagevorrichtung unterscheidet sich hiervon im wesentlichen dadurch, daß hier die oberen Transportrollen (26, 27) ausschließlich unter Schwerkraftwirkung gegen eine Transportwalze (6) gedrückt werden, welche die Funktion von unteren Transportrollen übernimmt.A sheet delivery device known from DE-OS-2 045 148 essentially differs from this in that the upper transport rollers (26, 27) are pressed exclusively under the force of gravity against a transport roller (6) which takes over the function of lower transport rollers.
Aufgabe der vorliegenden Erfindung ist es, eine Bogenauslagevorrichtung, insbesondere für Kleinoffsetmaschinen, zu schaffen, die eine einfache und problemlose Handhabung hinsichtlich Einstellung der Formatbreite und des jeweiligen Anpreßdruckes der verwendeten Rollen ermöglicht und darüberhinaus eine schonende Behandlung der auszulegenden Bogen gewährleistet.The object of the present invention is to provide a sheet delivery device, in particular for small offset presses, which enables simple and problem-free handling with regard to setting the format width and the respective contact pressure of the rolls used and also ensures gentle handling of the sheets to be laid out.
Die gestellte Aufgabe wird erfindungsgemäß durch eine Vorrichtung gemäß den Merkmalen des Patentanspruches 1 gelöst.The object is achieved according to the invention by a device according to the features of claim 1.
Diese Bogenauslagevorrichtung zeichnet sich dabei vor allem durch eine ausgesprochen kompakte und übersichtliche Bauweise aus. Ein wesentlicher Vorteil ist letztlich auch, daß alle Einstell- und Justierarbeiten selbst dann vorgenommen werden können, wenn die Maschine in Betrieb ist.This sheet delivery device is characterized above all by an extremely compact and clear construction. A major advantage is ultimately that all setting and adjustment work can be carried out even when the machine is in operation.

Bei der in Fig. 1 dargestellten Kleinoffsetmaschine wird ein zu bedruckender Bogen 5 vom Stapel 1 vereinzelt und über eine zuführeinrichtung 2 einem Druckzylinder 3 zugeführt. In dem Spalt zwischen diesem und einem Gummizylinder 4 erfolgt die Übertragung des Druckbildes. Der bedruckte Bogen 5 wird dann von einer Bogenauslagevorrichtung 6 übernommen und einem Auslagestapel 7 zugeführt. Das Druckbild erhält der Gummizylinder 4 dabei von einem ihm vorgelagerten Plattenzylinder 8, welcher über eine Auftragswalze 9, die mit einem Farb- und Feuchtwerk 10, 11 in Kontakt steht, die Druckfarbe erhält. Über den Steuerpult 12 erhält die Maschine die entsprechenden Befehle vom Maschinenbediener. Gummituchwascheinrichtung 61, Folieneinzugs-und Etcheinrichtung 62, 63 sind weitere wesentliche Bauelemente der Maschine.In the small offset press shown in FIG. 1, a
Fig. 2 nun zeigt in einer vergrößerten Darstellung die dem Druckzylinder 3 zugeordnete erfindungsgemäße Bogenauslagevorrichtung 6. Dabei ist ein Abstreifer 13 vorgesehen, der den Bogen 5 nach dessen Freigabe durch die Bogengreifer 14 vom Druckzylinder 3 löst und nachgeschalteten Transportrollen 21, 22 zuführt. Der aus mehreren über die Maschinenbreite in einer entsprechenden Anordnung verteilt angeordneten Abstreiferfingern 15 bestehende Abstreifer 13 ist mit seiner, diese Abstreiferfinger 15 tragenden Schiene 16 an den Seitenwänden 17, 18 der Maschine über Befestigungsschrauben 19 befestigt (Fig. 3). Nach Freigabe des Bogens 5 durch die Bogengreifer 14 und nach Abstreifen der Bogenvorderkante wird über eine am Druckzylinder 3 anliegende Führungsrolle 20 der hintere Bereich des Bogens 5 in Kontakt mit dem Druckzylinder 3 gehalten bis die Übernahme durch die Transportrollen 21, 22 erfolgt ist.2 now shows, in an enlarged view, the
Letztere sind dabei als über die Bogenbreite gesehen der linken und rechten Bogenseite zugeordnete zylindrische Gummirollen 21 und an diese mit einer gewissen Anpreßkraft angestellte Anpreßrollen 22 ausgebildet. Der Anpreßdruck ist dabei über eine später noch näher zu beschreibende Einrichtung einstellbar.The latter are in the form of
Den Transportrollen 21, 22, d.h, insbesondere der zylindrischen Gummirolle 21 nachgeschaltet ist desweiteren ein jeweils links- und rechtsseitig angeordnetes Leitblech 23, welches derart geformt ist, daß der auszulegende Bogen 5 eine leichte Wölbung erhält, so daß seine innere Stabilität erhöht wird, um seinen weiteren Weg zum Auslagestapel 7 störungsfreier zu gestalten.The
Führungsrolle 20 und Anpreßrolle 22 sind an einem als länglicher Lagerbock ausgebildeten Tragelement 24 gelagert, welches auf einer abgeflachten Rundachse 25 in Achsrichtung verschiebbar und mittels Knebelschraube 26 feststellbar geführt ist. Die abgeflachte Rundachse 25 ist durch Befestigungsschrauben 27 an den Seitenwänden 17,18 der Maschine befestigt. Das Tragelement 24 stützt sich dabei mit seiner gabelförmigen Ausladung 28 auf einer weiteren Achse 29 ab, deren Lagerung ebenfalls mittels Befestigungsschrauben 27 an den beiden Seitenwänden17, 18 erfolgt.
Jede Führungsrolle 20 ist desweiteren auf einem Hebel 31 drehbar gelagert, wobei dieser wiederum um einen Lagerbolzen 32 des Tragelementes 24 schwenkbar ist und sich an diesem über Druckfeder 33, Führungsbolzen 34 und Mutter 35 mit zugehöriger Kontermutter 30 federnd abstützt, um dadurch mit vorgebbarer Andrückkraft am Druckzylinder 3 anzuliegen.Each
Auch die Lagerung der Anpreßrolle 22 am Tragelement 24 erfolgt durch einen Achszapfen 36 und über einen Hebel 37, dessen anderes Ende über einen Lagerzapfen 38 mit dem Tragelement 24 verbunden ist. Über einen in einer Bohrung 39 des Tragelementes 24 geführten Bolzen 40, auf den eine Druckfeder 41 einwirkt, wird die Anpreßkraft über einen weiteren mit dem Lagerzapfen 38 verbundenen Hebel 60 auf die Anpreßrolle 22 übertragen.The
Mittels einer auf die Druckfeder 41 einwirkenden Einstellschraube 42 mit einem vorgegebenen Einstellbereich kann die Anpreßkraft variiert werden. Der Einstellbereich umfaßt dabei beispielsweise weniger als eine Schraubenumdrehung.The contact pressure can be varied by means of an adjusting
Zwischen Knebelschraube 26 sowie Einstellschraube 42 und dem, dem Druckzylinder 3 zugewandten Bereich der Bogenauslagevorrichtung 6 ist ein Schutzschild 44 vorgesehen. Dadurch bleibt die freie Zugänglichkeit der vorgenannten Verstellelemente erhalten.A
Gummirolle 21 sowie Leitblech 23 sind über einen Bügel 45 mit dem Tragelement 24 verbunden. Sie werden somit gleichzeitig mit der Anpreßrolle 22 seitlich verstellt. Leitblech 23 und Gummirolle 21 können darüberhinaus mittels Rändelmuttern 46, die auf eine Lasche 43 des Bügels 45 einwirken, relativ zu der Anpreßrolle 22 seitlich verstellt werden. Wie aus Fig. 4 ersichtlich sind die Rändelmuttern 46 auf einen Gewindestift 47 aufgeschraubt, welcher in eine Gewindebohrung 48 des Tragelementes 24 eingreift. Der Bügel 45 ist dabei an der unteren abgeflachten Seite 49 des Tragelementes 24 lösbar und entsprechend seitlich verschiebbar befestigt und umgreift weiterhin die Gummirolle 21.
Letztere ist, mit einem leichten Gleitsitz versehen, auf einer mit einer Längsnut 57 ausgestatteten Antriebswelle 50 gelagert und kann aufgrund der Mitnahmeverbindung mit dem Bügel 45 axial leicht verschoben werden.The latter, with a slight sliding fit, is mounted on a
Die Antriebswelle 50 ist dabei über Kugellager 51 in Achshalterungen 52 gelagert, welche jeweils an den beiden Seitenwänden 17, 18 über Befestigungsschrauben 53 befestigt sind.The
Ein auf der Antriebswelle 50 drehfest gelagertes Zahnrad 54 vermittelt dieser über weitere Zahnräder 55, 56 der Antriebskette die Drehbewegung. Das zugeordnete Zahnrad 55 ist dabei auf einem mittels Befestigungsschrauben 58 an der Seitenwand 18 gehaltenen Lagerzapfen 59 drehbar gelagert.A
