Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Aufwickeln von Papierstreifen, wie solche insbesondere für bedruckte Papierstreifen bei Streifendruckern zu Dokumentationszwecken Verwendung finden.The invention relates to a device for winding paper strips, such as those used in particular for printed paper strips in strip printers for documentation purposes.

Solche Aufwickelvorrichtungen bestehen in der Regel aus einem angetriebenen Wickelkern mit Zuführ- und Umlenkrollen sowie Bandspannarm. Hierbei ist von Nachteil, der der Wickelkern jeweils seitlich ganz herausnehmbar und damit verlierbar ist. Desweiteren ist das Einfädeln des Streifenanfangs oft schwierig und schließlich ist nur eine geringe Wickeldichte wegen fehlender Führung zu erreichen.Such winding devices usually consist of a driven winding core with feed and deflection rollers and a belt tensioning arm. The disadvantage here is that the winding core can be completely removed from the side and thus lost. Furthermore, threading the beginning of the strip is often difficult and finally only a low winding density can be achieved due to the lack of guidance.

Es ist nun Aufgabe der Erfindung, diese Nachteile zu vermeiden und neben der Unverlierbarkeit des Wickelkerns und einfachem Einfädelvorgang auch eine gute Wickeldichte für die Aufbewahrung des Bandwickels zu erreichen.It is an object of the invention to avoid these disadvantages and, in addition to the captivity of the winding core and simple threading process, to achieve a good winding density for the storage of the tape winding.

Zur Lösung dieser Aufgabe kennzeichnet sich die Vorrichtung zum Aufwickeln von Papierstreifen nach dem Oberbegriff des Anspruchs 1 gemäß der Erfindung durch einen ausziehbaren, gabelartigen Wickelkern mit seitlicher Auszugsbegrenzung, wobei der Wickelkern vorzugsweise vier jeweils um 90° auf dem Wickelkern versetzte Wickelstäbe besitzt, derart, daß der aufgenommene Papierwickel nach dem Ausziehen des Wickelkerns frei entnehmbar ist. Hierdurch wird das Einführen des Streifenanfangs erleichtert durch einfaches Einbringen zwischen den Wickelstäben und Bildung der ersten Wicklungen.To solve this problem, the device for winding paper strips according to the preamble of claim 1 is characterized by an extendable, fork-like winding core with lateral extension limitation, the winding core preferably having four winding rods, each offset by 90 ° on the winding core, in such a way that the paper roll taken up can be freely removed after the winding core has been pulled out. This makes it easier to insert the beginning of the strip by simply inserting it between the winding bars and forming the first windings.

Hierbei kann der gabelartige Wickelkern mit den Wickelstäben in Bohrungen der Radnaben beidseitiger Antriebsräder verschiebbar und am Auszug seinerseits über angeschrägte Nuten mit Anschlagrand durch einen eingreifenden Sprengring begrenzt sein, sodaß ein Verlust des Wickelkerns vermieden wird.Here, the fork-like winding core with the winding bars in bores of the wheel hubs on both sides of the drive wheels can be displaced and, in turn, can be limited by an engaging snap ring by means of bevelled grooves with a stop edge, so that loss of the winding core is avoided.

Wie aus der Zeichnung ersichtlich wird, besteht die Wickelvorrichtung aus dem Gehäuse 1 mit beidseits gekapselten Antriebsrädern 2 für den ausziehbaren, gegabelten Wickelkern 3 und den beiden Zuführ- und Umlenkrollen 4, 5 sowie dem Spannarm 6, welcher unter Wirkung der Gelenkfeder 7 in die Gehäuseschlitzung 8 zwischen den beiden Umlenkrollen 4, 5 zur Spannung des Papierstreifens 9 greift.As can be seen from the drawing, the winding device consists of the housing 1 with drive wheels 2 encapsulated on both sides for the extendable, forked winding core 3 and the two feed and deflection rollers 4, 5 and the tensioning arm 6, which under the action of the articulated spring 7 into the housing slot 8 engages between the two deflection rollers 4, 5 for tensioning the paper strip 9.

Der ausziehbare, gegabelte Wickelkern 3 besitzt hier jeweils um 90° auf den Wickelkreis versetzte Wickelstäbe 10, welche nach dem Einführen des Papierstreifens 9 bei hochgestelltem Spannarm 6 (Fig. 7 und 8) und Aufwickeln des Bandwickels 11 bei schlaufenbildendem Spannarm 6 (Fig. 5 und 6) der Entnahme desselben (11) nach seitlichem Ausziehen des Wickelkerns 3 dienen. Die Wickelstäbe 10 sind in Bohrungen 12 der Radnaben 13 der beidseitigen Antriebsräder 2 für den Wickelkern 3 zum seitlichen Ausziehen verschiebbar. Hierbei ist der Auszug seinerseits über angeschrägte Nuten 14 mit Anschlagrand 15 im Zusammenwirken mit dem in der offenen Rillung 16 liegenden Sprengring 17 begrenzt, wie aus Figur 9 und 10 ersichtlich wird. Hiermit kann der Wickelkern 3 nicht vollständig entnommen werden und verloren gehen, sondern ist nur soweit ausziehbar, daß der Bandwickel 11 frei entnehmbar ist.The extendable, forked winding core 3 here has winding rods 10 which are offset by 90 ° on the winding circle and which, after the insertion of the paper strip 9 with the tension arm 6 raised (FIGS. 7 and 8) and the winding of the tape roll 11 with the loop-forming tension arm 6 (FIG. 5 and 6) serve to remove the same (11) after the winding core 3 has been pulled out laterally. The winding bars 10 are displaceable in bores 12 of the wheel hubs 13 of the drive wheels 2 on both sides for the winding core 3 for lateral pulling out. Here, the extract is in turn limited by chamfered grooves 14 with stop edge 15 in cooperation with the snap ring 17 located in the open groove 16, as can be seen from FIGS. 9 and 10. With this, the winding core 3 cannot be completely removed and lost, but can only be pulled out to the extent that the tape winding 11 can be freely removed.

Der Bandspannarm 6 dient über den Schalteranschlag 18 bei Schleifenbildung des Papierstreifens 9 zur Steuerung des hier nicht dargestellten Antriebsmotors, welcher über Ritzel 19 die Räder 2 und damit den Wickelkern 3 antreibt. Hierbei hat der Bandspannarm 6 eine schräge Arbeitskante 20, welche mit dem Ringanschlag 21 der zugehörigen Umlenkrolle 5 für eine einwandfreie Bandzufuhr sowie eine feste Bandwicklung sorgt.The belt tensioning arm 6 is used via the switch stop 18 when the paper strip 9 forms loops to control the drive motor, not shown here, which drives the wheels 2 and thus the winding core 3 via pinions 19. Here, the band tensioning arm 6 has an oblique working edge 20 which, with the ring stop 21 of the associated deflecting roller 5, ensures perfect band feed and a firm band winding.

In der Zeichnung ist beispielsweise noch ein Streifendrucker 22 mit Druckerrolle 23 und Druckerhebel 24 bei Bandführung 9 gezeigt.In the drawing, for example, a strip printer 22 with a printer roller 23 and a printer lever 24 is shown at the tape guide 9.
