Description

Die Erfindung betrifft eine Transporteinrichtung zum Zuführen und Abführen eines Endlosformulars zu einer Schreibwalze, die in Gestellwänden eines Druckwerkes gelagert ist, mit paarweise zusammenwirkenden Transportketten, die das um die Schreibwalze herumgeführte Formular vor und hinter der Schreibwalze erfassen und auf in Seitenwänden der Transporteinrichtung gelagerten Wellen angeordnet sind, von denen mindestens eine antreibbar ist.The invention relates to a transport device for feeding and discharging an endless form to a platen roller, which is mounted in the frame walls of a printing unit, with paired transport chains, which capture the form around the platen roller in front of and behind the platen roller and arranged on shafts mounted in side walls of the transport device are, at least one of which can be driven.

Aus der US-PS 3161 277 ist eine Vorrichtung zum dauernden Spannen eines Endlosformulares bekannt, das von einem Transportkettenpaar einer Schreibwalze zugeführt und wieder abgeführt wird. Über die ganze Breite des Endlosformulares ist nahe der Schreibwalze eine Welle angeordnet, durch die das Endlosformular zwischen den Transportketten und der Schreibwalze gestrafft gehalten wird. Um diese Straffung auch bei abgeschwenkter Schreibwalze zu erreichen, ist die Welle absenkbar gelagert. Hierzu sind seitlich am Gestell des Druckwerkes Gleitschienen vorgesehen, die durch einen Exzenter verschoben werden. Ausserdem besitzen die Gleitschienen Schlitze, in die ein Stift der Lagerung der Schreibwalze eingreift. Dadurch sind das Heben und Senken der Welle mit dem Schwenken der Schreibwalze kraftschlüssig und zwangsweise gekoppelt.From US-PS 3161 277 a device for the permanent tensioning of a continuous form is known, which is fed from a pair of transport chains to a platen roller and removed again. A shaft is arranged over the entire width of the continuous form near the platen roller, by means of which the continuous form is held taut between the transport chains and the platen roller. In order to achieve this tightening even when the platen is swiveled out, the shaft is mounted so that it can be lowered. For this purpose, slide rails are provided on the side of the frame of the printing unit, which are displaced by an eccentric. In addition, the slide rails have slots into which a pin of the platen roller bearing engages. As a result, the lifting and lowering of the shaft are positively and positively coupled with the pivoting of the platen roller.

Die bekannte Anordnung hat den Nachteil, dass durch die starre Kopplung der Abstand zwischen den Transportketten und der Schreibwalze während des Betriebes immer konstant bleibt, so dass die eingelegten Endlosformulare nur dann unter gleicher Spannung beim Transport stehen, wenn sie stets die gleiche Stärke besitzen.The known arrangement has the disadvantage that the rigid coupling means that the distance between the transport chains and the platen roller always remains constant during operation, so that the continuous forms inserted are only under the same tension during transport if they always have the same thickness.

Bekanntlich aber werden in Büromaschinen unterschiedliche Endlosformulare eingelegt. So können sowohl die Papierstärke der einzelnen Lagen als auch die Anzahl der Lagen verschieden sein. Eine Beschädigung der Transportlöcher des Endlosformulares, insbesondere wenn dieses nur aus einer Papierlage besteht, ist möglich, insbesondere wenn der Abstand zwischen den Transportketten und der Walze unveränderbar auf ein mehrlagiges Endlosformular abgestellt ist. Bei mehreren Lagen steht das Endlosformular zusätzlich ständig unter unkontrollierbaren Spannungskräften infolge von Herstellungstoleranzen der Schreibwalze und der Transportketten sowie deren Abstand zueinander, so dass die seitliche Verbindung der einzelnen Papierlagen mehr oder weniger stark zerstört wird.As is well known, however, different endless forms are inserted into office machines. Both the paper thickness of the individual layers and the number of layers can be different. Damage to the transport holes of the continuous form, particularly if it consists of only one layer of paper, is possible, in particular if the distance between the transport chains and the roller is fixed on a multilayer continuous form. In the case of several layers, the continuous form is additionally constantly under uncontrollable tension forces as a result of manufacturing tolerances of the platen roller and the transport chains and their spacing from one another, so that the lateral connection of the individual paper layers is more or less destroyed.

Der Erfindung liegt die Aufgabe zugrunde, eine Transporteinrichtung zu schaffen, die bedarfsweise auf in ihrer Stärke unterschiedliche Endlosformulare oder Formularsätze in einfacher Weise einstellbar ist und bei der der hierzu erforderliche Aufwand gering ist.The invention has for its object to provide a transport device that can be easily adjusted to different forms or sets of forms with different strengths and in which the effort required for this is low.

Diese Aufgabe wird dadurch gelöst, dass mindestens an einer der beiden Seitenwände der Einrichtung ein Betätigungshebel schwenkbar gelagert ist, der einerseits einen Ansatz zur Rasterung in verschiedenen Schwenkstellungen und andererseits eine Lageröse besitzt, mit der die Seitenwände in den entsprechenden Schwenkstellungen des Betätigungshebels auf den an den Gestellwänden des Druckwerkes befestigten Bolzen aufliegen, und dass die Seitenwände jeweils mit einem Langloch versehen sind, das einen weiteren an den Gestellwänden befestigten Bolzen umgreift, derart, dass beim Verschwenken des Betätigungshebels die Seitenwände in den Langlöchern gleiten und dabei sich der Abstand der Transportketten und der Schreibwalze ändert.This object is achieved in that an actuating lever is pivotally mounted on at least one of the two side walls of the device, which on the one hand has an attachment for ratcheting in different pivot positions and on the other hand has a bearing eyelet with which the side walls in the corresponding pivot positions of the actuating lever on the Frame walls of the printing unit are fastened by bolts, and that the side walls are each provided with an elongated hole which engages around a further bolt fastened to the frame walls, such that when the actuating lever is pivoted, the side walls slide in the elongated holes and the distance between the transport chains and the Platen changes.

Werden einerseits die Lagerösen aus zwei gegenüberliegenden Klemmnasen gebildet und wird andererseits das Langloch offen ausgebildet, so ist die gesamte Transporteinrichtung als module Einheit auf das Druckwerk aufsteckbar. Die beiden an den Seitenwänden der Transporteinrichtung angeordneten Betätigungshebel können einzeln gelagert oder auch durch eine Welle verdrehungsfest miteinander verbunden werden. Während im ersten Fall jeder Betätigungshebel einzeln bewegt werden muss, und eine eigene Rasterung besitzen muss, genügt im zweiten Fall die Verschwenkung und Rasterung eines der beiden Betätigungshebel.If on the one hand the bearing eyelets are formed from two opposing clamping lugs and on the other hand the elongated hole is made open, the entire transport device can be plugged onto the printing unit as a modular unit. The two actuating levers arranged on the side walls of the transport device can be individually supported or can also be connected to one another in a rotationally fixed manner. While in the first case each actuating lever has to be moved individually and has to have its own catch, in the second case the pivoting and catch of one of the two actuating levers is sufficient.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispieles näher erläutert. Es zeigen:

  • Fig. 1 die perspektivische Ansicht der Transporteinrichtung,
  • Fig. die Seitenansicht der Transporteinrichtung im Stadium des Aufsteckens auf das Druckwerk und
  • Fig.3 die Seitenansicht der aufgesteckten Transporteinrichtung.
The invention is explained in more detail below using an exemplary embodiment. Show it:
  • 1 is a perspective view of the transport device,
  • Fig. The side view of the transport device in the stage of plugging onto the printing unit and
  • 3 shows the side view of the attached transport device.

Die Transporteinrichtung für Endlosformulare ist als leicht montierbare, aufsteckbare Baugruppe ausgebildet. Um ein leichtes Aufsetzen auf das Druckwerk zu ermöglichen, wurde eine Klemmverbindung gewählt. Die Seitenwände 1 und 2 haben je ein offenes Langloch 3. Die Bolzen 4 und 5 zum Einstecken der Transporteinrichtung auf das Druckwerk sind an den Gestellwänden 6 und 7 (Fig.1) befestigt, die Bestandteile des Druckwerkes sind. Die Verkleidung 8 des Druckwerkes, die nur in den Figuren 2 und 3 teilweise dargestellt ist, hat rechts und links der Schreibwalze 12 eine Öffnung, die das Einführen der Seitenwände 1 und 2 ermöglicht.The transport device for continuous forms is designed as an easily assembled, attachable assembly. A clamp connection was chosen to enable easy placement on the printing unit. The side walls 1 and 2 each have an open slot 3. The bolts 4 and 5 for inserting the transport device onto the printing unit are fastened to the frame walls 6 and 7 (FIG. 1), which are components of the printing unit. The cladding 8 of the printing unit, which is only partially shown in FIGS. 2 and 3, has an opening on the right and left of the platen roller 12 which enables the side walls 1 and 2 to be inserted.

Fig. zeigt, wie die Transporteinrichtung aufgesteckt wird. Durch Verkanten der Transporteinrichtung nach vorne werden die Langlöcher 3 über die Bolzen 4 gesteckt und die Transporteinrichtung anschliessend wieder nach hinten zurückgeschwenkt bis die Klemmnasen 9 und 10, die eine Lageröse bilden, über den zweiten Bolzen 5 einrasten.Fig. Shows how the transport device is plugged on. By tilting the transport device to the front, the elongated holes 3 are inserted over the bolts 4 and the transport device is then pivoted back again until the clamping lugs 9 and 10, which form a bearing eye, snap into place over the second bolt 5.

Um zu verhindern, dass durch Überbeanspruchung die beiden Klemmnasen 9 und 10 zerstört werden, sind die Seitenwände 1 und 2 je mit einer Kante 11 versehen, die in der Funktionsstellung der Transporteinrichtung auf dem zugeordneten Bolzen 5 aufliegt und ein weiteres Durchdrücken beim Aufstecken verhindert und eine Entlastung der Lageröse bewirkt. Beim Aufstecken kommen die Verzahnungen des auf der Schreibwalze 12 befestigten Zahnrades 13 und des an der Transporteinrichtung befindlichen Zahnrades 14 in Eingriff und stellen das Getriebe zur Kraftübertragung von der Schreibwalze 12 zur Antriebswelle 21 der Transportketten 16 dar.In order to prevent the two clamping lugs 9 and 10 from being destroyed by overstressing, the side walls 1 and 2 are each provided with an edge 11 which is in the functional position the transport device rests on the associated pin 5 and prevents further pushing through when plugging in and relieves the bearing eye. When plugged in, the teeth of the gear 13 fastened on the platen roller 12 and the gear 14 located on the transport device engage and represent the transmission for power transmission from the platen roller 12 to the drive shaft 21 of the transport chains 16.

Die lösbare Halterung der Transporteinrichtung auf dem Druckwerk kann auch auf andere Weise erfolgen. Es ist dabei nur zu beachten, dass die Transporteinrichtung durch den Betätigungshebel 15 auf dem Druckwerk verschoben werden kann.The transport device can also be detachably held on the printing unit in another way. It should only be noted that the transport device can be moved on the printing unit by the actuating lever 15.

Wird ein Endlosformular mittels der Transportketten 16 der Schreibwalze zugeführt und hinter der Druckposition wieder abgeführt, muss der Abstand A je nach Formulardicke bzw. je nach Anzahl der Formularlagen variabel sein. Eine besonders günstige Lösung ist die fixe Zuordnung des Abstandes A zur Formulardicke bzw. zu den Formularlagen. Dazu wird der Abstand zwischen Transportketten 16, insbesondere deren Antriebswelle 21, und der Schreibwalze 12, insbesondere deren Lagerwelle 22, einstellbar ausgeführt. Hierzu dient der Betätigungshebel 15, der gleichzeitig die lösbare Befestigung der Transporteinrichtung auf dem Druckwerk bewirkt.If an endless form is fed to the platen by means of the transport chains 16 and removed again after the printing position, the distance A must be variable depending on the form thickness or depending on the number of form layers. A particularly favorable solution is the fixed assignment of the distance A to the form thickness or to the form layers. For this purpose, the distance between transport chains 16, in particular their drive shaft 21, and the platen roller 12, in particular their bearing shaft 22, is made adjustable. For this purpose, the actuating lever 15, which at the same time effects the releasable fastening of the transport device on the printing unit.

Der Betätigungshebel 15 ist im Drehlager 17 an den Seitenwänden 1 und 2 der Transporteinrichtung befestigt. Er besitzt im oberen Teil einen angeformten Arm 18, der als Fixierfeder wirkt. Dieser rastet in vier Stellungen ein, die als Langlöcher 19 in die Seitenwände 1 und 2 gestanzt sind. Am Handgriff 20, der ebenfalls Bestandteil des Betätigungshebels 15 ist und zweifach abgewinkelt ist, so dass er durch eine Öffnung 23 der Seitenwände 1 und 2 hindurchgeführt werden kann, wird die Verstellung des Abstandes A vorgenommen, wobei die Zahl 1 den maximalen Abstand A1 für die Einstellung für Ein- oder Zweifach-Formulare und die Zahl 4 den minimalen Abstand A4 für die Einstellung für Sechs- oder Achtfach-Formulare angibt. Beim Verstellen vom Rastpunkt 1 zum Rastpunkt 4 dreht der Betätigungshebel 15 um den Bolzen 5. Dadurch wird das Drehlager 17 in Pfeilrichtung nach links verlagert, wodurch die Seitenwände 1 und 2 im Langloch 3 ebenfalls nach links gleiten. Durch diese Verschiebung wird der Abstand A bis auf den Minimalwert A4 verringert. Beim Verschwenken des Betätigungshebels 15 von der Rasterung 4 zurück nach der Rasterung 1 erfolgt der Vorgang in umgekehrter Richtung in Pfeilrichtung nach rechts.The actuating lever 15 is fastened in the pivot bearing 17 on the side walls 1 and 2 of the transport device. It has an integrally formed arm 18 in the upper part, which acts as a fixing spring. This engages in four positions, which are punched as elongated holes 19 in the side walls 1 and 2. On the handle 20, which is also part of the actuating lever 15 and is angled twice so that it can be passed through an opening 23 of the side walls 1 and 2, the adjustment of the distance A is carried out, the number 1 being the maximum distance A1 for the Setting for single or double forms and the number 4 indicates the minimum distance A4 for the setting for six or eight forms. When moving from the locking point 1 to the locking point 4, the actuating lever 15 rotates about the bolt 5. As a result, the pivot bearing 17 is shifted to the left in the direction of the arrow, as a result of which the side walls 1 and 2 in the slot 3 also slide to the left. This shift reduces the distance A to the minimum value A4. When pivoting the actuating lever 15 from the grid 4 back to the grid 1, the process takes place in the opposite direction in the direction of the arrow to the right.

Das Verschieben der Transporteinrichtung ist nur möglich, wenn die beiden Zahnräder 13 und 14 so angeordnet sind, dass in der Mittelstellung der Transporteinrichtung, d.h. bei den Rastungen 2 bzw. 3, das Zahnrad 14 annähernd senkrecht über dem Zahnrad 13 steht. Ein Verschieben des Zahnrades 14 innerhalb eines bestimmten Bereiches nach vorn und hinten beeinflusst dann die Verzahnungsverhältnisse im Eingriffbereich nur unwesentlich und ist akzeptabel.Moving the transport device is only possible if the two gear wheels 13 and 14 are arranged so that in the central position of the transport device, i.e. in the detents 2 and 3, the gear 14 is approximately perpendicular to the gear 13. Moving the gearwheel 14 forward and backward within a certain range then has only an insignificant effect on the toothing conditions in the engagement area and is acceptable.

In dem beschriebenen Beispiel ist die Transporteinrichtung so beschrieben und dargestellt, dass sie auf das Gestell des Druckwerkes bedarfsweise aufsetzbar und wieder abnehmbar ist. Aus diesem Grunde sind die Langlöcher und die Lagerösen 9, 10 jeweils nach aussen offen. Es ist aber auch möglich, sofern die Transporteinrichtung fest mit dem Gestell verbunden werden kann und nicht abnehmbar ausgeführt werden muss, die Langlöcher und die Lagerösen geschlossen auszuführen. In diesem Falle sind dann die Lagerbolzen 4, 5 in die zugeordneten Löcher entweder während der Montage des Druckers einzustecken oder durch federndes Ausbiegen der Seitenwände 1, einzurasten.In the example described, the transport device is described and illustrated in such a way that it can, if necessary, be placed on and removed from the frame of the printing unit. For this reason, the elongated holes and the bearing eyelets 9, 10 are each open to the outside. However, if the transport device can be firmly connected to the frame and does not have to be removable, it is also possible to make the elongated holes and the eyelets closed. In this case, the bearing bolts 4, 5 are then to be inserted into the assigned holes either during assembly of the printer or by resilient bending of the side walls 1.
