Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a device according to the preamble of claim 1.
Im Bereich von Bogenanlagen in Bogen verarbeitenden Maschinen sind Einrichtungen zur Erfassung der Lage der Vorderkanten von auszurichtenden Bogen bekannt. Hierzu werden optische oder andere berührungslos wirkende Sensoren sogenannten Vordermarken, die der Ausrichtung der Bogen an ihrer Vorderkante dienen, zugeordnet.in the Range of sheetfed in sheet processing machines are Means for detecting the position of the leading edges of be aligned Bow known. For this purpose, optical or other non-contact acting sensors so-called leading brands, the orientation the sheet at its front edge serve, assigned.
Aus
der
Die Anordnung der Sensoren im Bereich der Bogenausrichtung ist nicht näher beschrieben.The Arrangement of the sensors in the area of sheet alignment is not described in more detail.
Die Aufgabe der Erfindung ist, in einer Vorrichtung nach dem Oberbegriff des Patentanspruchs 1, eine vereinfachte Bedienbarkeit, Einstellbarkeit und Austauschbarkeit zu erreichen.The The object of the invention is, in a device according to the preamble of claim 1, a simplified operability, adjustability and To achieve interchangeability.
Die Lösung dieser Aufgabe gestaltet sich nach den Merkmalen des Patentanspruchs 1.The solution This task is designed according to the features of the claim 1.
Vorteile der Erfindung sind, dass kein mechanischer Umbau mehr notwendig ist durch Aus- und Einbau unterschiedlicher Teile, wenn Abfrageabstand aufgrund drucktechnischer Anforderungen verändert werden muß. Außerdem ergibt sich ein schnellerer (weil leichterer) Austausch von defekten Lichttastern.
- – Der Lichttaster sitzt passgenau in einer einfachen Aufnahme, die nahezu spielfrei in Führungen läuft und nach vorne hin, d. h. in Papierlaufrichtung, herausnehmbar ist.
- – Die Mitnahme des Aufnehmers bei der Einstellung der Vordermarke erfolgt durch eine Spindel, über die der Abfrageabstand des Lichttasters zur Vordermarke wiederum selbst einstellbar ist.
- – Ein Anschlag begrenzt den maximal zulässigen Abfrageabstand des Lichttasters zur Vordermarke.
- – Zum Austausch eines defekten Lichttasters kann dieser mit der Aufnahme durch Herausdrehen der Spindel und damit durch Trennung von der Vordermarke und Herausziehen aus den Führungen entnommen werden.
- - The light sensor sits snugly in a simple shot that runs almost free of play in guides and forward, ie in the paper direction, is removable.
- - The entrainment of the pickup in the adjustment of the leading edge is carried out by a spindle, via which the interrogation distance of the light button to the front mark is again adjustable itself.
- - A stop limits the maximum permissible interrogation distance of the light button to the front mark.
- - To replace a defective light scanner this can be removed with the recording by unscrewing the spindle and thus by separation from the front and pulling out of the guides.
Ein
weiterer Lösungsansatz
ergibt sich wie folgt:
Es ist eine Abkoppelung der Lichttasterführung von einer
einzelnen Vordermarke vorgesehen. Die Einstellung der Lichttasterposition
erfolgt mittels eines eigenen Motors, gesteuert über ein Steuerprogramm der
Maschine, z.B. ein Leitstandprogramm, in Abhängigkeit des vorgewählten Profils
aller einzeln motorisch eingestellten Vordermarken und unter Berücksichtigung
des jeweiligen Reflexionsgrades des Bedruckstoffes.Another approach is as follows:
There is provided a decoupling of the light guide from a single front brand. The adjustment of the light sensor position by means of its own motor, controlled by a control program of the machine, such as a control station program, depending on the preselected profile of all individually motorized front brands and taking into account the respective reflectance of the printing material.
Vorteile der Erfindung sind, dass kein mechanischer Umbau mehr notwendig ist durch Aus- und Einbau unterschiedlicher Teile, wenn Abfrageabstand aufgrund drucktechnischer Anforderungen verändert werden muß. Außerdem ergibt sich ein schnellerer (weil leichterer) Austausch von defekten Lichttastern.advantages The invention is that no mechanical conversion more necessary is by removing and installing different parts when interrogation distance must be changed due to printing requirements. It also gives a faster (because easier) replacement of defective light sensors.
Im Folgenden wird ein Ausführungsbeispiel anhand der einzigen Figur näher beschrieben.in the Below is an embodiment based closer to the single figure described.
Die
Lösung
gestaltet sich wie folgt:
Im Anlagebereich einer Bogen verarbeitenden
Maschine ist eine Reihe von Vordermarken
In the investment area of a sheet-processing machine is a series of front-end brands

Die
Funktion des Lichttasters bzw. Sensors
- – Der
Sensor
3 sitzt passgenau in einer einfachen Aufnahme3a , die nahezu spielfrei in Führungen7 läuft und nach vorne hin, d. h. in Papierlaufrichtung T, herausnehmbar ist. - – Die
Funktion der Ankoppelung der Position der Aufnahme
3a an die Führung7 bei der Einstellung der Vordermarke1 erfolgt durch eine Spindel4 , über die der Abfrageabstand des Sensors3 zur Vordermarke1 hin wiederum selbst unabhängig einstellbar ist. - – Ein
Anschlag
5 für die Aufnahme3a in der Führung7 begrenzt den maximal zulässigen Abfrageabstand des Sensors3 zur Vordermarke1 . - – Zum
Austausch eines defekten Sensors
3 kann dieser mit der Aufnahme3a durch Herausdrehen der Spindel4 und damit durch Trennung von der Vordermarke1 und Herausziehen aus den Führungen7 entnommen werden. - – Jede
Spindel
4 und somit jede Aufnahme3a bzw. jeder Sensor3 kann mittels eines motorischen Antriebes fernverstellbar angeordnet sein.
- - The sensor
3 fits snugly in a simple shot3a , almost free of play in guides7 runs and towards the front, ie in the paper direction T, is removable. - - The function of coupling the position of the recording
3a to the leadership7 when adjusting the front-end1 done by a spindle4 , about which the interrogation distance of the sensor3 to the front1 In turn, even independently adjustable. - - An attack
5 for receiving3a in the lead7 limits the maximum allowable interrogation distance of the sensor3 to the front1 , - - To replace a defective sensor
3 can this with the recording3a by unscrewing the spindle4 and thus by separation from the front-end1 and pulling out of the guides7 be removed. - - Every spindle
4 and thus every shot3a or each sensor3 can be arranged remotely adjustable by means of a motor drive.
