Definitions
- the invention relates to a device for the lateral alignment of sheets by means of a convertible side alignment device which conveys the sheets to a stop by means of a suction slide
- the suction slide being designed as a suction slide with a suction device and having a cam roller which by means of a force of springs acting on the suction slide can be adjusted to a first or second control cam by means of a shift fork, the control cams being arranged in mirror image relative to one another on a drive sleeve, the suction slide with suction cup being movable in the direction of a reversible stop depending on the cam roller bearing on one of the control cams, and the device is slidably provided for right or left stop in the printing machine as required.
- a device of this type is known from US-A-3 860 233.
- the sheets to be processed in the machine may be attached to the left or right or to align them to the left or right.
- a change of the stop side in the machine is particularly necessary if the front or back of a sheet must be printed in register. In this case, the sheet side edge that was chipped when printing on the front must also be chipped when printing on the back.
- Such a device shows e.g. DE-PS 1 950 305.
- This device is a side alignment device that can be switched from pull to slide. To switch from pulling to pushing, this side alignment device is provided with interchangeable upper parts, one part being designed as a slide part and the other as a pulling part.
- Another device (DE-PS 1 278 449) describes a device in which a suction slide is provided on the right and left of the machine. These suction slides are coupled together and are driven together by a curve. To switch from right to left stop, the bow stop and a bow driver attached to the suction slide are exchanged. By moving the curve, the suction slide can be moved in an opposite direction.
- This device also has the disadvantage that considerable conversion work is required to convert from right to left.
- the invention is therefore based on the object of creating a device which can be used on the right and left of the printing press without extensive changeover work having to be carried out on the device. Furthermore, the device should be compact, so that it takes up little space in the printing press.
- the advantage of this device is, in particular, that a printing press only has to be provided with a side alignment device. It is also advantageous that the change from right to left stop can be done in just two easy steps.
- the device is designed such that after the sheets have been aligned on the side stop, i.e. after the suction movement is zero, blowing air can be supplied to the suction. This ensures a safe separation between the suction cup and the sheet.
- the side alignment device 1 essentially consists of a housing 2, a drive sleeve 3 mounted in the housing 2, which is provided with control cams 4, 5 which are arranged in mirror image to one another, a suction pipe 6 on which a suction slide 7 is slidably mounted and a suction cup 8 carries and a removable stop 9, which can be inserted into corresponding bores 10 of the housing 2. Furthermore, the housing 2 has a suction air chamber 11 which can be acted upon with suction air via an air connection 12. The suction pipe 6 is connected to the suction air chamber 11 via a suction air line 13 and a valve.
- the drive sleeve 3 carrying the control cams 4, 5 is mounted in the housing 2 in radial bearings 15, 16.
- a shift fork 18 which can be actuated via an eccentric 17 is provided, between the claws 19, 20 of which springs 21, 22 are arranged which are pushed over the suction tube 6 and which counter the suction slide 7, which is provided with a cam roller 23, depending on the position of the shift fork 18 press a control curve 4 or 5.
- the control cam 4 is, as shown, on its side opposite the cam roller 23 with a Provided recess 14 and acts with the suction air chamber 11 as a valve.
- the recess 14 is arranged so that the suction 8 can be acted upon by suction air during its movement in the direction of the stop 9. So that the control curve 4 is tight against the suction air chamber 11, a compression spring 24 with a spring constant that is greater than the spring constant of the springs (21, 22) is arranged so that it drives the drive sleeve 3 and thus the control curve 4 as in Fig. 1 shown presses to the left.
- An axial bearing 25 is provided between the housing 2 and the control cam 5.
- the device If the device is to be used on the opposite side of the machine, it is moved to its required position, the stop 9 is moved into the existing pipes 10 and the shift fork 18 is adjusted with the eccentric 12 so that the spring 21 is in effect and the spring 22 is set from their effect.
- the cam roller is now on curve 5.
- the alignment process is then carried out in the same way as previously described.
- the mirror-inverted arrangement of the control cams 4 ensures that both the suction movement and the suction air supply for right and left stop occur at the same time. A change of curves or the like is not necessary.
- control curve 5 like the control curve 4, could be designed as a valve slide, so that blown air can also be blown into the suction pipe 6 with an additional air line and air chamber.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum seitlichen Ausrichten von Bogen mittels einer umstellbaren Seitenausrichtvorrichtung, welche die Bogen mittels eines Saugschiebers an einen Anschlag fördert, wobei der Saugschieber als Saugschlitten mit Sauger ausgebildet ist und eine Kurvenrolle aufweist, welche mittels einer auf den Saugschlitten einwirkenden Kraft von Federn mittels einer Schaltgabel wahlweise an eine erste oder zweite Steuerkurve anstellbar ist, wobei die Steuerkurven spiegelbildlich gegeneinander auf einer Antriebshülse angeordnet sind, wobei der Saugschlitten mit Sauger je nach Anlage der Kurvenrolle an einer der Steuerkurven in Richtung eines umsteckbaren Anschlages bewegbar ist, und wobei die Vorrichtung je nach Bedarf für Rechts- oder Linksanschlag in der Druckmaschine verschiebbar vorgesehen ist.The invention relates to a device for the lateral alignment of sheets by means of a convertible side alignment device which conveys the sheets to a stop by means of a suction slide, the suction slide being designed as a suction slide with a suction device and having a cam roller which by means of a force of springs acting on the suction slide can be adjusted to a first or second control cam by means of a shift fork, the control cams being arranged in mirror image relative to one another on a drive sleeve, the suction slide with suction cup being movable in the direction of a reversible stop depending on the cam roller bearing on one of the control cams, and the device is slidably provided for right or left stop in the printing machine as required.
Eine Vorrichtung dieser Gattung ist durch die US-A- 3 860 233 bekannt.A device of this type is known from US-A-3 860 233.
Je nach Art der Bogenverarbeitung ist es erforderlich, die zu verarbeitenden Bogen in der Maschine links oder rechts anzuschlagen bzw. nach links oder rechts auszurichten. Ein Wechsel der Anschlagseite in der Maschine wird insbesondere dann notwendig, wenn Vorder- oder Rückseite eines Bogens registergenau bedruckt werden müssen. In diesem Falle muß die Bogenseitenkante, die beim Bedrucken der Vorderseite angeschlagen wurde, auch beim Bedrucken der Rückseite angeschlagen werden.Depending on the type of sheet processing, it may be necessary to attach the sheets to be processed in the machine to the left or right or to align them to the left or right. A change of the stop side in the machine is particularly necessary if the front or back of a sheet must be printed in register. In this case, the sheet side edge that was chipped when printing on the front must also be chipped when printing on the back.
Aus diesem Grund sind fast alle Druckmaschinen mit zwei derartigen Seitenausrichtvorrichtungen ausgerüstet:
- Es sind noch weitere Vorrichtungen bekannt, welche umstellbar ausgebildet sind, d.h. nach zwei Seiten hin arbeiten.
- Other devices are known which are designed to be convertible, ie work on two sides.
Eine derartige Vorrichtung zeigt z.B. die DE-PS 1 950 305.Such a device shows e.g. DE-PS 1 950 305.
Bei dieser Vorrichtung handelt es sich um eine von Ziehen auf Schieben umstellbare Seitenausrichtvorrichtung. Zum Umstellen von Ziehen auf Schieben ist diese Seitenausrichtvorrichtung mit austauschbaren Oberteilen versehen, wobei das eine Teil als Schieberteil und das andere als Ziehteil ausgebildet ist.This device is a side alignment device that can be switched from pull to slide. To switch from pulling to pushing, this side alignment device is provided with interchangeable upper parts, one part being designed as a slide part and the other as a pulling part.
Der Nachteil dieser Vorrichtung besteht jedoch darin, daß die Seitenausrichtvorrichtung bei einer Umstellung von Ziehen auf Schieben umgebaut werden muß. Auch ist es als Nachteil anzusehen, daß für vorgenannten Fall zwei dieser Seitenausrichtvorrichtungen vorgesehen werden müssen.The disadvantage of this device, however, is that the side alignment device must be converted when changing from pulling to pushing. It is also to be regarded as a disadvantage that two of these side alignment devices must be provided for the aforementioned case.
In einer weiteren Patentschrift (DE-PS 1 278 449) wird eine Vorrichtung beschrieben, bei der je ein Saugschieber rechts und links an der Maschine vorgesehen ist. Diese Saugschieber sind miteinander gekoppelt und werden gemeinsam von einer Kurve angetrieben. Zur Umstellung von Rechts- auf Linksanschlag werden der Bogenanschlag und ein am Saugschieber befestigter Bogenmitnehmer gegeneinander ausgetauscht. Durch Verschieben der Kurve ist eine Verschiebung der Saugschieber in eine entgegengesetzte Richtung möglich. Auch diese Vorrichtung hat den Nachteil, daß zur Umstellung von Rechts- auf Lir.ksanschtag erhebliche Umrüstarbeiten anfallen.Another device (DE-PS 1 278 449) describes a device in which a suction slide is provided on the right and left of the machine. These suction slides are coupled together and are driven together by a curve. To switch from right to left stop, the bow stop and a bow driver attached to the suction slide are exchanged. By moving the curve, the suction slide can be moved in an opposite direction. This device also has the disadvantage that considerable conversion work is required to convert from right to left.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung zu schaffen, welche an der Druckmaschine rechts und links verwendbar ist, ohne daß umfangreiche Umstellarbeiten an der Vorrichtung vorgenommen werden müssen. Weiterhin soll die Vorrichtung kompakt ausgebildet sein, so daß sie in der Druckmaschine wenig Raum benötigt.The invention is therefore based on the object of creating a device which can be used on the right and left of the printing press without extensive changeover work having to be carried out on the device. Furthermore, the device should be compact, so that it takes up little space in the printing press.
Gelöst wird diese Aufgabe entsprechend dem Kennzeichen des ersten Patentanspruchs.This object is achieved in accordance with the characteristics of the first claim.
Der Vorteil dieser Vorrichtung liegt insbesondere darin, daß eine Druckmaschine nur mit einer Seitenausrichtvorrichtung versehen werden muß. Weiterhin ist es von Vorteil, daß die Umstellung von Rechts- auf Linksanschlag mit nur zwei Handgriffen erfolgen kann. Bei einer besonderen Ausgestaltungsvariante ist die Vorrichtung so ausgebildet, daß nach Ausrichten der Bogen an dem Seitenanschlag, d.h. nachdem die Saugerbewegung gleich Null ist, dem Sauger Blasluft zuführbar ist. Hierdurch ist ein sicheres Trennen zwischen Sauger und Bogen gewährleistet.The advantage of this device is, in particular, that a printing press only has to be provided with a side alignment device. It is also advantageous that the change from right to left stop can be done in just two easy steps. In a special embodiment variant, the device is designed such that after the sheets have been aligned on the side stop, i.e. after the suction movement is zero, blowing air can be supplied to the suction. This ensures a safe separation between the suction cup and the sheet.
Nachfolgend ist die Vorrichtung an einem Ausführungsbeispiel näher erläutert.
- Fig. 1 zeigt eine Ansicht der Erfindung teilweise im Schnitt.
- Fig. 2 zeigt eine Seitenansicht von Fig. 1.
- Fig. 3 zeigt einen Ausschnitt aus Fig. 1 in einer Draufsicht.
- Fig. 4 zeigt eine weitere Ausgestaltungsvariante der Erfindung.
- Fig. 1 shows a view of the invention partially in section.
- FIG. 2 shows a side view of FIG. 1.
- FIG. 3 shows a detail from FIG. 1 in a top view.
- 4 shows a further embodiment variant of the invention.
Die Seitenausrichtvorrichtung 1 besteht im wesentlichen aus einem Gehäuse 2, einer im Gehäuse 2 gelagerten Antriebshülse 3, die mit Steuerkurven 4, 5 versehen ist, welche spiegelbildlich zueinander angeordnet sind, einem Saugrohr 6, auf dem ein Saugschlitten 7 verschiebbar gelagert ist und einen Sauger 8 trägt und einem umsteckbaren Anschlag 9,der in entsprechende Bohrungen 10 des Gehäuses 2 einsteckbar ist. Weiterhin weist das Gehäuse 2 eine Saugluftkammer 11 auf, die über einen Luftanschluß 12 nit Saugluft beaufschlagbar ist. Das Saugrohr 6 ist über eine Saugluftleitung 13 und ein Ventil mit der Saugluftkammer 11 verbunden. Die die Steuerkurven 4, 5 tragende Antriebshülse 3 ist im Gehäuse 2 in Radiallagern 15, 16 gelagert.The
Weiterhin ist eine über einen Exzenter 17 betätigbare Schaltgabel 18 vorgesehen, zwischen deren Klauen 19, 20 über das Saugrohr 6 geschobene Federn 21, 22 angeordnet sind, welche den Saugerschlitten 7, der mit einer Kurvenrolle 23 versehen ist, je nach Stellung der Schaltgabel 18 gegen eine Steuerkurve 4 oder 5 drücken.Furthermore, a shift fork 18 which can be actuated via an eccentric 17 is provided, between the claws 19, 20 of which springs 21, 22 are arranged which are pushed over the
Die Steuerkurve 4 ist, wie gezeigt, an ihrer der Kurvenrolle 23 gegenüberliegenden Seite mit einer Ausnehmung 14 versehen und wirkt mit der Saugluftkammer 11 als Ventil. Die Ausnehmung 14 ist dabei so angeordnet, daß der Sauger 8 während seiner Bewegung in Richtung Anschlag 9 mit Saugluft beaufschlagbar ist. Damit die Steuerkurve 4 dicht gegenüber der Saugluftkammer 11 anliegt, ist eine Druckfeder 24 mit einer Federkonstante, die größer ist als die Federkonstante der Federn (21, 22), so angeordnet, daß sie die Antriebshülse 3 und damit die Steuerkurve 4 wie in Fig. 1 dargestellt nach links drückt. Zwischen Gehäuse 2 und Steuerkurve 5 ist ein Axiallager 25 vorgesehen.The control cam 4 is, as shown, on its side opposite the cam roller 23 with a Provided
Die Funktion der Vorrichtung ist wie folgt:
- Wird die
Antriebshülse 3 z.B. von einer Antriebswelle 27 in Rotation versetzt, folgt die Kurvenrolle 23 der Steuerkurve 4, und derSauger 8 bewegt sich inRichtung Anschlag 9. DieAusnehmung 14 an der Steuerkurve 4 ist so angeordnet, daß kurz bevor sich derSauger 8 in Bewegung setzt, ein auszurichtender Bogen angesaugt wird. Dies wird dadurch erreicht, daß dieAusnehmung 14 dieSaugluftkammer 11 mit derSaugluftleitung 13 verbindet. Die Saugluft gelangt nun über dasSaugerrohr 6 und einen im Bereich desSaugschlittens 7 imSaugerrohr 6 vorgesehener Durchbruch 26 zumSauger 8. In dem Moment, in dem sich derSauger 5 an seinem Umkehrpunkt befindet, wird die Saugluft durch das Ventil abgestellt. Der auszurichtende Bogen gelangt vorher an denAnschlag 9 und wird ausgerichtet indem er amAnschlag 9 abgestreift wird.
- If the
drive sleeve 3 is set in rotation by a drive shaft 27, for example, the cam roller 23 follows the control cam 4 and thesuction pad 8 moves in the direction of thestop 9. Therecess 14 on the control cam 4 is arranged such that just before thesuction pad 8 sets in motion, a sheet to be aligned is sucked in. This is achieved in that therecess 14 connects thesuction air chamber 11 to thesuction air line 13. The suction air now reaches thesuction device 8 via thesuction pipe 6 and an opening 26 provided in the area of thesuction carriage 7 in thesuction pipe 6. At the moment when thesuction device 5 is at its turning point, the suction air is shut off by the valve. The sheet to be aligned reaches thestop 9 beforehand and is aligned by being stripped off at thestop 9.
Soll nun die Vorrichtung an der gegenüberliegenden Maschinenseite verwendet werden, so wird sie an ihre erforderliche Position verschoben, der Anschlag 9 wird in die vorhandenen Rohrungen 10 umgesteckt und die Schaltgabel 18 mit dem Exzenter 12 so verstellt, daß die Feder 21 in Wirkung und die Feder 22 aus ihrer Wirkung gesetzt wird. Die Kurvenrolle liegt nun an der Kurve 5 an. Der Ausrichtvorgang erfolgt dann gleich wie vorher beschrieben. Durch die spiegelbildliche Anordnung der Steuerkurven 4, ist gewährleistet, daß sowohl die Saugerbewegung als auch die Saugluftzufuhr für Rechts- und Linkanschlag absolut gleichzeitig erfolgt. Eine Umstellung von Kurven oder dgl. ist nicht erforderlich.If the device is to be used on the opposite side of the machine, it is moved to its required position, the
Die Steuerkurve 5 könnte ebenso wie die Steuerkurve 4 als Ventilschieber ausgebildet sein, so daß mit einer zusätzlichen Luftleitung und Luftkammer auch Blasluft in das Saugerrohr 6 einblasbar ist.The
