Description

Die vorliegende Erfindung betrifft eine Anordnung zum Separieren und Schneiden einer Bahn aus einem Endlosformularsatz gemäss dem Gattungsbegriff des unabhängigen Patentanspruchs 1.The present invention relates to an arrangement for separating and cutting a web from an endless form set according to the preamble of independent claim 1.

Die zunehmende Automation führt zu einer immer weiter verbreiteten Verwendung von Endlosformularsätzen. Diese bestehen aus einer Originalbahn und wenigstens einer Kopienbahn und entsprechend zwischengelegter Durchschreibepapierbahn, wie beispielsweise eine Kohlepapierbahn. Nach dem Drucken mit einem computergesteuerten Drucker müssen die einzelnen Bahnen separiert, die Seitenränder mit den Lochreihen abgeschnitten und die einzelnen Formulare müssen abgetrennt und wieder gestapelt werden. Da in den Endlosformularsätzen die einzelnen Bahnen miteinander verbunden sind, müssen zuerst diese Heftungen, z.B. die Kleber, in den Führungsrandlochungen aufgeschnitten werden, dann muss das Original losgelöst, das darunterliegende Kohlepapier und die Kopie bei einem Doppelpapiersatz je für sich gestapelt oder aufgerollt werden. Bei mehrlagigen Sätzen müssen entsprechend die weiteren Bahnen in der genannten Weise behandelt werden. Geräte für diesen Arbeitsschritt, sogenannte Separatoren, sind bekannt. Die einzelnen Stapel mit den Originalen und der Kopie oder den Kopien werden einem zweiten Gerät, der Schneidmaschine, zugeleitet, um die Ränder mit den Führungslochungen abzuschneiden und die einzelnen Formularblätter abzutrennen und zu stapeln. Dieser zuletzt genannte Vorgang wird für jede Kopie wiederholt.The increasing automation leads to an increasingly widespread use of continuous form sets. These consist of an original web and at least one copy web and correspondingly interspersed copy paper web, such as a carbon paper web. After printing with a computer-controlled printer, the individual webs must be separated, the side edges cut off with the rows of holes, and the individual forms must be separated and stacked again. Since the individual webs in the continuous form sets are connected with each other, these staplings, e.g. the glue, must first be cut in the leading edge perforations, then the original must be detached, the carbon paper underneath and the copy for a double paper set must be stacked or rolled up individually. In the case of multi-layer sets, the other lanes must be used accordingly be treated. Devices for this step, so-called separators, are known. The individual stacks with the originals and the copy or copies are fed to a second device, the cutting machine, in order to cut off the edges with the guide perforations and to separate and stack the individual form sheets. This latter process is repeated for each copy.

Neben Formularbahnen mit querverlaufenden Schwächungslinien sind auch solche ohne Schwächungslinien bekannt. Bei den erstgenannten genügt zum Abtrennen der Formularblätter, dass ein erster Anpressmitnehmer mit einer bestimmten Geschwindigkeit läuft und ein zweiter Mitnehmer stromabwärts des ersten eine grössere Geschwindigkeit aufweist, um so die Bahnen bei den Schwächungslinien zu durchtrennen. Da hier das Abtrennen bei gleichbleibendem Materialfluss geschieht, können der Separator und die Schneidemaschine kombiniert werden.In addition to form webs with transverse weakening lines, those without weakening lines are also known. In the case of the former, it is sufficient to tear off the form sheets that a first pressing driver runs at a certain speed and a second driver downstream of the first has a higher speed, so as to sever the webs at the lines of weakness. Since the separation takes place while the material flow remains the same, the separator and the cutting machine can be combined.

Anders bei den Formularbahnen ohne Schwächungslinien. Hier ist ein Balkenmesserpaar quer zur Vorschubrichtung vorhanden und die Papierbahn muss einen Augenblick angehalten werden, wenn das Messerpaar betätigt wird. Dies führt zu einer Arbeitsweise Vorschieben-Schneiden-Beschleunigen und Vorschieben, also einer zyklischen Arbeitsweise, während der Separator nur eine kontinuierliche Arbeitsweise kennt.It is different with the form webs without weakening lines. There is a pair of bar knives at right angles to the feed direction and the paper web must be stopped for a moment when the pair of knives is actuated. This leads to an operation of advancing, cutting, accelerating and advancing, that is to say a cyclic operation, while the separator only knows one continuous operation.

Es sind auch keine Kombinationen eines Separators mit einer Schneidmaschine mit einem Quermesser auf dem Markte erhältlich, die zufriedenstellend und störungsfrei arbeiten. Die Aufgabe der Erfindung wird demgemäss darin gesehen, eine solche Gerätekombination zu schaffen, die einfach aufgebaut ist und die einen störungsfreien Betrieb gewährleistet.There are also no combinations of a separator with a cutting machine with a transverse knife available on the market that work satisfactorily and without problems. The object of the invention is accordingly seen in creating such a device combination which is simple in construction and which ensures trouble-free operation.

Erfindungsgemäss wird dies durch die Merkmale im kennzeichnenden Teil des unabhängigen Patentanspruchs erreicht.According to the invention this is achieved by the features in the characterizing part of the independent claim.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung erläutert. Es zeigen:

  • Fig. 1 einen Aufriss einer Anordnung zum Separieren und Schneiden von Formularbahnen aus Endlosformularsätzen, und
  • Fig. 2 einen Grundriss der Anordnung nach Fig. 1.
An embodiment of the invention is explained below with reference to the drawing. Show it:
  • Fig. 1 is an elevation of an arrangement for separating and cutting form webs from continuous form sets, and
  • 2 is a plan view of the arrangement of FIG. 1st

In Fig. 1 und 2 lassen sich die beiden Geräte leicht erkennen, nämlich das Schneidgerät A mit einer Transportvorrichtung 10 und einem Rollenmesserpaar 20 zum Abschneiden der Ränder 2 mit den Transportlochreihen 1. In bekannter Weise bestehen die Rollenmesserpaare aus zwei einzelnen Messerrollen 21, 22. Ein Balkenmesser mit einem ortsfesten Messer 23 und einem beweglichen Messer 24 dient zum Abtrennen der einzelnen Formularblätter 7.1 and 2, the two devices can be easily recognized, namely the cutting device A with a transport device 10 and a pair of roller knives 20 for cutting off the edges 2 with the rows of transport holes 1. In a known manner, the pair of roller knives consist of two individual knife rollers 21, 22. A bar knife with a fixed knife 23 and a be movable knife 24 serves to separate the individual form sheets 7.

Das Gerät B ist im wesentlichen ein Separator, dem der Stapel 2 aus dem gefalteten Endlosformularsatz 3 eingangsseitig zugeführt wird. Mit einer Transportvorrichtung 30 wird der Endlosformularsatz 3 bewegt. Vor der Transportvorrichtung 30 befindet sich ein Paar Multiflex-Messer 31, 32 zum Auftrennen der Heftungen zwischen den einzelnen Bahnen des Endlosformularsatzes 3. Stromabwärts der Transportvorrichtung 30 ist ein . Trennblech 40 angeordnet, durch das der abgetrennte Teil des Formularsatzes oder der Restformularsatz 6 nach hinten gegen den Stapel 2 umgelenkt wird, damit er auf einer Ablage 41 zu einem Stapel 8 aufgestapelt werden kann.The device B is essentially a separator to which the stack 2 from the folded continuous form set 3 is fed on the input side. The endless form set 3 is moved with a transport device 30. In front of the transport device 30 there is a pair of multiflex knives 31, 32 for separating the stitches between the individual webs of the continuous form set 3. A downstream of the transport device 30 is a. Partition plate 40 is arranged through which the separated part of the form set or the remaining form set 6 is deflected backwards against the stack 2 so that it can be stacked on a shelf 41 to form a stack 8.

Die Durchschreibepapierbahn 5 wird aussenseitig über das Trennblech 40 gezogen und mit einem Haspel 50 zu einer Rolle aufgewickelt.The carbonless paper web 5 is drawn on the outside over the dividing plate 40 and wound up into a roll with a reel 50.

Die Originalschriftpapierbahn 4 wird der nachfolgenden oder zweiten Transportvorrichtung 10 zugeleitet und wird im Gerät A in der beschriebenen Weise verarbeitet.The original writing paper web 4 is fed to the subsequent or second transport device 10 and is processed in device A in the manner described.

Der Haspel 5 besteht aus vier Fingern 51, 52, 53 und 54 und wird durch den Antrieb für die Transportvorrichtungen 10, 30, die Messerpaare 20 und die Querbalkenmesser 23, 24 über eine Rutschkupplung 55 mit einstellbarem Mitnehmerdruck angetrieben.The reel 5 consists of four fingers 51, 52, 53 and 54 and is driven by the drive for the transport devices 10, 30, the knife pairs 20 and the crossbeam knives 23, 24 are driven via a slip clutch 55 with adjustable driving pressure.

Im Betrieb hat sich gezeigt, dass mit der ersten Transportvorrichtung 30, die den bis auf die getrennte Heftung noch intakten Endlosformularsatz 3 transportiert, die Abnahme vom Stapel 2 gleichmässig erfolgt. Auch hat sich die Anordnung der Multiflexmesser 31, 32 stromaufwärts der ersten Transportvorrichtung 30 als günstig herausgestellt, weil der Formularsatz 3 durch das Eingreifen der Transportzähne nach dem Auftrennen der Heftung noch zusammengehalten wird.It has been shown in operation that the first transport device 30, which transports the continuous form set 3, which is still intact except for the separate stapling, takes place evenly from the stack 2. The arrangement of the multiflex knives 31, 32 upstream of the first transport device 30 has also proven to be advantageous because the set of forms 3 is still held together by the engagement of the transport teeth after the stapling has been separated.

Die zyklische Arbeitsweise des Gerätes A, die sich in älteren Anordnungen auf den Haspel 50 auswirkte, indem beim Anhalten der Papierbahn 4 der Haspel 50 eine Zugkraft auf das Kohlepapier 5 ausübte und, weil das Kohlepapier nur eine geringe Zugfestigkeit hat, konnte oftmals festgestellt werden, dass dieses in der Folge zerriss.The cyclical mode of operation of the device A, which had an effect on the reel 50 in older arrangements, in that when the paper web 4 stopped, the reel 50 exerted a tensile force on the carbon paper 5 and, because the carbon paper has only a low tensile strength, could often be found, that this tore up as a result.

Mit der stromaufwärtigen Transportvorrichtung 30 wird die Abgabe des Kohlepapiers 5 zum Haspel 50 gesteuert, das heisst, die erste Transportvorrichtung 30 wirkt auf den Haspel 40 ein und stellt dessen gleichmässige Drehzahl auf die Fördergeschwindigkeit der Transportvorrichtung (30) ein. Somit können beide Transportvorrichtungen 10, 30 angehalten werden, wenn der Transport der Papierbahn 4 während der Betätigung der Balkenmesser 21, 22 angehalten wird und damit wird auch der Haspel 50 angehalten.With the upstream transport device 30, the delivery of the carbon paper 5 to the reel 50 is controlled, that is to say the first transport device 30 acts on the reel 40 and adjusts its uniform speed to the conveying speed of the transport device (30). Both transport devices 10, 30 can thus be stopped, if the transport of the paper web 4 is stopped during the operation of the bar knives 21, 22 and thus the reel 50 is also stopped.

Oder die erste Transportvorrichtung 30 kann durchgehend den Endlosformularsatz 3 fördern und die zweite Transportvorrichtung 10 kann intermittierend arbeiten. Beide Möglichkeiten bewirken kein Fehlverhalten des Haspels 50.Or the first transport device 30 can continuously convey the endless form set 3 and the second transport device 10 can work intermittently. Both options do not cause the reel 50 to malfunction.
