Abstract

A device for registering a sheet against a side stop on the feed table of a printing press which includes a suction head flushly recessed in the table and reciprocated for lateral shifting movement, a draft of suction being applied to the head timed with the lateral shifting movement so that the sheet is affirmatively shifted into contact with the side stop. Subsequently, a puff of air is applied to the head timed with the completion of the shifting movement to free the sheet from the head in readiness for removal of the sheet from the table. An auxiliary nozzle recessed in the table in a position adjacent the head is permanently connected to a source of air pressure and arranged approximately parallel to the surface of the table for producing a moving film of air under the sheet in the direction of the side stop to ensure that the sheet remains against the side stop when the suction is no longer effective and until the sheet is removed from the table. The rate of air flow from the auxiliary nozzle and the strength of the puff of air through the head are under the control of respective throttle valves having operating knobs in convenient upwardly facing positions adjacent the suction head.

Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbegriff des Patentanspruchs.The invention relates to a device according to the preamble of the claim.

Der Zweck derartiger Vorrichtungen besteht insbesondere darin, einen Bogen zur exakten Weiterbe- oder Weiterverarbeitung nach einer Seitenkante auszurichten und zwar so, daß dieser Ausrichtvorgang dann beendet ist, wenn der Bogen erfaßt und in die Maschine gefördert wird.The purpose of such devices is, in particular, to align a sheet for exact further processing or further processing according to a side edge, in such a way that this alignment process is ended when the sheet is gripped and conveyed into the machine.

Bei der aus der DE-AS 2824932 bekannten Vorrichtung geschieht dies durch einen von unten auf den Bogen einwirkenden mit Saugluft beaufschlagten Sauger, der den Bogen erfaßt und ihn kurvengesteuert an einen Anschlag fördert. Nach Anlage des Bogens an dem Anschlag, wird die Saugluft abgestellt und zur besseren Trennung des Bogens vom Sauger Blasluft in diesen eingeleitet.In the device known from DE-AS 2824932, this is done by means of a suction device, which acts on the sheet from below with suction air and which detects the sheet and conveys it to a stop in a curve-controlled manner. After the sheet has been placed against the stop, the suction air is switched off and blown air is introduced into the suction device for better separation of the sheet.

Der Nachteil dieser Vorrichtung besteht insbesondere darin, daß je nach eingestellter Blasluft beim Abstellen der Saugluft keine Gewähr dafür gegeben ist, daß der Bogen seine Lage nicht mehr verändert. Ebenso ist es schwierig und damit auch nachteilig, die exakte Blasluftmenge für alle gängigen Papiersorten einzustellen.The disadvantage of this device is, in particular, that, depending on the blown air set when the suction air is switched off, there is no guarantee that the arc will no longer change its position. It is also difficult and therefore disadvantageous to set the exact amount of blown air for all common types of paper.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung zu schaffen, bei der sichergestellt ist, daß sich der Bogen nach dem Abstellen der Saugluft nach dem Ausrichtvorgang in seiner Lage nicht mehr verändern kann, und die eine einfache und leicht einstellbare Blasluftmengenregulierung aufweist.The invention is therefore based on the object to provide a device in which it is ensured that the sheet can no longer change in its position after the suction air has been switched off after the alignment process, and which has a simple and easily adjustable blowing air quantity regulation.

Gelöst wird diese Aufgabe durch den kennzeichnenden Teil des Patentanspruchs.This problem is solved by the characterizing part of the patent claim.

Der Vorteil dieser Vorrichtung liegt insbesondere darin, daß der Bogen durch den Blasluftstrom der Blasdüse auch dann noch gegen den Anschlag »gefördert« wird, wenn die Saugluft des Saugers bereits abgestellt ist. Dies wird insbesondere dadurch erreicht, daß die für die Ausrichtung vorgesehenen, zusammenwirkenden Komponenten, wie die von der Blasdüse austretende Blasluftmenge und auch die Menge der in den Sauger eingeleiteten Blasluft, einfach und bedienungsfreundlich verändert werden kann.The advantage of this device is, in particular, that the sheet is "conveyed" against the stop by the blow air flow from the blow nozzle even when the suction air of the suction device has already been switched off. This is achieved in particular in that the cooperating components provided for the alignment, such as the amount of blown air emerging from the blower nozzle and also the amount of blown air introduced into the suction device, can be changed simply and in a user-friendly manner.

Nachfolgend ist an einem Ausführungsbeispiel die Erfindung näher erläutert.

  • Fig. 1 zeigt eine schematische Ansicht der Seitenausrichtvorrichtung in einer perspektiven Ansicht von oben.
  • Fig. zeigt den schematischen Verlauf der Luftleitungen innerhalb des Gehäuses mit den Anschlüssen für Saug- und Druckluft, sowie die für die Blas- und Saugluftsteuerung bestimmten Steuerkurven.
The invention is explained in more detail below using an exemplary embodiment.
  • 1 shows a schematic view of the side alignment device in a perspective view from above.
  • Fig. Shows the schematic course of the air lines within the housing with the connections for suction and compressed air, as well as the control curves intended for blowing and suction air control.

Der Grundkörper 1 ist so ausgebildet, daß seine Oberseite 2 als Bogenführungsfläche 3 dient. Auf dieser Oberseite 2 ist ein Bogenanschlag 4 angeordnet, der auch gleichzeitig zur Aufnahme der Luftmengenregelventile 5, 6 dient. Weiterhin ist eine Blasdüse 7 vorgesehen, die einen Luftstrom parallel zur Bogenführungsfläche 3 und gegen den Bogenanschlag 4 richtet. In einer Führung 8 in der Bogenführungsfläche 3 ist der Sauger 9 geführt, mit dem die auszurichtenden Bogen gegen den Bogenanschiag 4 gefördert werden.The base body 1 is designed so that its top 2 serves as a sheet guiding surface 3. On this top 2, a sheet stop 4 is arranged, which also serves to accommodate the air flow control valves 5, 6. Furthermore, a blowing nozzle 7 is provided, which directs an air flow parallel to the sheet guide surface 3 and against the sheet stop 4. The suction device 9 is guided in a guide 8 in the sheet guide surface 3, with which the sheets to be aligned are conveyed against the sheet flange 4.

Der innere Aufbau des Grundkörpers 1 sieht verschiedene Luftleitungen für Saug- und Blasluft vor, die von einem Rotationsventil 12 im Takt der Maschine gesteuert wird.The inner structure of the base body 1 provides various air lines for suction and blown air, which is controlled by a rotary valve 12 in time with the machine.

Die Luftleitung 10 für Blasluft führt von einem Druckluftanschluß 11 zu einem Luftmengenregelventil 5 und von dort aus zur Blasdüse 7. Aus der Luftleitung 10 kann mittels des Rotationsventils 12 für Blasluft in eine weitere Luftleitung 13 für pulsierende Blasluft geleitet werden. Diese Blasluft wird einem weiteren Luftmengenregelventil 6 zugeführt, von welchem aus die Blasluft zum Sauger 9 geleitet werden kann. Diese pulsierende Blasluft wird dabei so gesteuert, daß diese erst dann einsetzt, wenn der Sauger 9 ei nen auszurichtenden Bogen sicher an den Bogenanschlag 4 gefördert hat.The air line 10 for blown air leads from a compressed air connection 11 to an air quantity regulating valve 5 and from there to the blower nozzle 7. From the air line 10, a further air line 13 for pulsating blown air can be conducted by means of the rotary valve 12 for blown air. This blown air is fed to a further air quantity control valve 6, from which the blown air can be directed to the suction device 9. This pulsating blowing air is controlled in such a way that it only starts when the suction cup 9 has safely conveyed a sheet to be aligned to the sheet stop 4.

Mit einer zweiten Ebene des Rotationsventils 12 wird auch gleichzeitig die Saugluft für den Sauger 9 gesteuert. Von dieser Ebene aus führt eine Luftleitung 14 für Saugluft zu einer Luftteitung 15 für kombinierte Saug- und Blasluft die den Sauger 9 mit Blas- und Saugluft versorgt.With a second level of the rotary valve 12, the suction air for the suction device 9 is also controlled simultaneously. From this level, an air line 14 for suction air leads to an air line 15 for combined suction and blown air which supplies the suction device 9 with blown and suction air.

Mit dem Luftmengenregelventil 5 ist es somit möglich, die Luftmenge für die kontinuierlich blasende Blasdüse 7 einzustellen, während mit dem Luftmengenregelventil 6 die durch das Rotationsventil 12 erzeugte pulsierende Blasluft für den Sauger 9 eingestellt werden kann.With the air volume control valve 5 it is thus possible to adjust the air volume for the continuously blowing blowing nozzle 7, while with the air volume control valve 6 the pulsating blowing air generated by the rotary valve 12 can be adjusted for the suction device 9.
