Abstract

The invention relates to an apparatus for printing on receipt forms or the like with a one-line printing mechanism. In order also to be able to print the form with a number of lines, this is gripped firmly on a sliding carriage and the carriage is moved along into different line positions on the printing mechanism. A mechanical control mechanism with a cam plate serves for driving the sliding carriage. The closed cam plate makes possible a control in the retraction and extension direction with a corresponding rotation of the cam plate. The exact positioning of the sliding carriage is done by a ratchet in the control mechanism. An electronic control takes care of an automatic running of one printing operation.

Description

Die Erfindung betrifft eine Einrichtung der im Oberbegriff des Anspruches 1 genannten Art.The invention relates to a device of the type mentioned in the preamble of claim 1.

Eine derartige Einrichtung dient dazu, den zu bedruckenden Bogen aufzunehmen, ihn zeilengenau dem Druckwerk zuzuführen und ihn wieder in eine Entnahmeposition zu bringen.Such a device is used to receive the sheet to be printed, to feed it to the printing unit line by line and to bring it back into a removal position.

Es ist bereits eine Einrichtung der gattungsgemässen Art bekannt, bei welcher der Schlitten mittels eines handbetätigten Drehknopfes bewegt wird; zum Einziehen des Schlittens muss der Drehknopf in einer Richtung, zum Ausschieben in der Gegenrichtung betätigt werden (US-PS 3 426 356). Eine derartige manuelle Handhabung ist jedoch umständlich und langsam und deshalb für viele Bereiche der modernen Datenverarbeitung nicht mehr zeitgemäss. Auch die Klemmung des Bogens wird über einen gesonderten Hebel von Hand betätigt, was die Handhabung der Einrichtung weiterhin erschwert. Auch für eine Automatisierung durch Verwendung von motorischen Antrieben für die Schlittenbewegung und die Klemmeinrichtung ist die bekannte Konstruktion weitgehend ungeeignet, weil dazu ein zwei Drehrichtungen aufweisender, äusserst genau positionierbarer Antriebsmotor sowie ein gesonderter Stellmotor für die Betätigung der Klemmung erforderlich wären, was sowohl mechanisch als auch bezüglich der Steuerung einen erheblichen Aufwand bedeuten würde.A device of the generic type is already known, in which the slide is moved by means of a manually operated rotary knob; to retract the slide, the rotary knob must be operated in one direction, to push it out in the opposite direction (US Pat. No. 3,426,356). However, such manual handling is cumbersome and slow and is therefore no longer appropriate for many areas of modern data processing. The sheet is also clamped manually using a separate lever, which further complicates the handling of the device. The known construction is also largely unsuitable for automation by using motorized drives for the slide movement and the clamping device, because a drive motor with two directions of rotation, which can be positioned very precisely, and a separate servomotor for actuating the clamp would be required, both mechanically and would mean a considerable effort in terms of control.

Es ist die Aufgabe der Erfindung, eine Einrichtung der gattungsgemässen Art zu schaffen, welche einen vollautomatischen Betrieb bei einfachem Aufbau, insbesondere unter Verwendung nur eines Antriebes, ermöglicht.It is the object of the invention to provide a device of the generic type which enables fully automatic operation with a simple structure, in particular using only one drive.

Diese Aufgabe ist erfindungsgemäss durch die im Kennzeichen des Anspruches 1 enthaltenen Merkmale gelöst.This object is achieved according to the invention by the features contained in the characterizing part of claim 1.

Schwingantriebe stellen sehr einfache mechanische Baugruppen dar, die es ermöglichen, die gegenläufigen Bewegungen des Schlittens mit einem in einer Drehrichtung umlaufenden Antriebsmotor zu bewerkstelligen, wie weiter hinten genauer ausgeführt wird. Ausserdem wird der Antriebsmotor auch noch dazu verwendet, die Betätigungsmittel zum Lösen der Klemmung dann zu betätigen, wenn sich der Schlitten in seiner Anfangsposition befindet, in der der Bogen eingelegt oder entnommen werden kann. Die erfindungsgemässe Konstruktion ermöglicht demnach ein vollautomatisches Klemmen, Einziehen und Ausschieben des Bogens für den Druckvorgang mit einem einzigen Antriebsmotor, welcher gleichzeitig der Antrieb für die eigentliche Druckeinrichtung sein kann, wie ebenfalls noch genauer ausgeführt wird.Vibratory drives represent very simple mechanical assemblies which make it possible to achieve the opposite movements of the slide with a drive motor rotating in one direction of rotation, as will be explained in more detail further on. In addition, the drive motor is also used to actuate the actuating means for releasing the clamping when the carriage is in its initial position in which the sheet can be inserted or removed. The construction according to the invention accordingly enables a fully automatic clamping, drawing in and pushing out of the sheet for the printing process with a single drive motor, which can also be the drive for the actual printing device, as is also explained in more detail.

In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass der Schwingantrieb wenigstens ein schwingendes Zahnsegment aufweist, welches in wenigstens eine am Schlitten ausgebildete Zahnstange eingreift. Um ein Verkanten des Schlittens auszuschliessen und eine absolute Parallelführung zu gewährleisten, sind vorzugsweise zwei parallel zueinander verlaufende Zahnstangen vorgesehen, denen jeweils ein Zahnsegment zugeordnet ist. In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Schlitten mit wenigstens einer gegen eine Anlagefläche des Schlittens anliegenden Blattfeder als Klemmung für das Formular versehen ist und dass an der Blattfeder ein Abhebestift angeordnet ist, welcher durch eine von der Zahnstangenrückseite her in den Verzahnungsbereich verlaufende Bohrung in eine Zahnlücke ragt und durch einen Zahn des Zahnsegmentes in der der Anfangsstellung des Schlittens entsprechenden Stellung im Sinne eines Abhebens der Feder verschoben wird. Wenn das Formular nach dem Druckvorgang wieder in seine Anfangsstellung ausgeschoben wird, wird auf diese Weise die Klemmung gelöst und das Formular zur Entnahme freigegeben.In a preferred embodiment of the invention it is provided that the oscillating drive has at least one oscillating toothed segment which engages in at least one toothed rack formed on the slide. In order to rule out tilting of the slide and to ensure absolute parallel guidance, two toothed racks running parallel to one another are preferably provided, each of which is assigned a toothed segment. In a further embodiment of the invention, it is provided that the slide is provided with at least one leaf spring bearing against a bearing surface of the slide as a clamp for the form and that a lifting pin is arranged on the leaf spring, which extends through a hole running from the rear of the rack into the toothing area protrudes into a tooth space and is displaced by a tooth of the toothed segment in the position corresponding to the initial position of the slide in the sense of lifting the spring. If the form is pushed out to its initial position after printing, the clamp is released in this way and the form is released for removal.

Der Schwingantrieb ist erfindungsgemäss über ein Steuergetriebe mit einem in einer Drehrichtung umlaufenden Antriebsmotor gekoppelt. Das Steuergetriebe umfasst eine Kurvenscheibe mit einer geschlossenen, etwa herzkurvenförmigen Steuerkurve, wobei in die Steuerkurve ein mit einem Schwinghebel verbundener Steuerstift eingreift und der Schwinghebel auf einer Schwingachse befestigt ist, die mit dem Schwingantrieb der Vorschubeinrichtung verbunden ist. Die Steuerkurve weist erfindungsgemäss zwei getrennte Bereiche auf, nämlich einen ersten, der Einzugsbewegung des Schlittens entsprechenden Bereich sowie einen zweiten, der Ausschiebebewegung des Schlittens entsprechenden Bereich, die bei jedem Druckvorgang nacheinander durchlaufen werden. Während der Einzugsbewegung dreht sich die Kurvenscheibe kontinuierlich, bis der Schlitten seine untere, vollständige eingezogene Stellung inne hat. Die Ausschiebebewegung erfolgt dagegen diskontinuierlich von Zeile zu Zeile und zurück bis in die Anfangsstellung. Wie weiter vorne schon erwähnt wurde, drückt in dieser Stellung ein Zahn des Zahnsegmentes auf den Anhebestift und löst auf diese Weise die Klemmung, so dass das Formular entnommen und ein neues eingelegt werden kann.According to the invention, the oscillating drive is coupled via a control gear to a drive motor rotating in one direction of rotation. The control gear comprises a cam disc with a closed, approximately heart-shaped control cam, wherein a control pin connected to a rocker arm engages in the cam and the rocker arm is fastened to a rocker shaft which is connected to the rocker drive of the feed device. According to the invention, the control curve has two separate areas, namely a first area corresponding to the retraction movement of the slide and a second area corresponding to the pushing-out movement of the slide, which are run through in succession during each printing process. During the retraction movement, the cam disc rotates continuously until the carriage is in its lower, fully retracted position. The push-out movement, on the other hand, takes place discontinuously from line to line and back to the starting position. As already mentioned above, in this position a tooth of the toothed segment presses on the lifting pin and in this way releases the clamp so that the form can be removed and a new one inserted.

Um das neue Formular wieder zu klemmen, muss der Abhebestift wieder freigegeben werden. Dazu ist erfindungsgemäss vorgesehen, dass die Schwingachse, die das Zahnsegment trägt, längsverschieblich gelagert ist und dass die Kurvenscheibe einen mit dem kurvenseitigen Ende der Schwingachse zusammenwirkenden Nocken trägt, welcher diese wenigstens zu Beginn des ersten Bereiches der Steuerkurve verschiebt derart, dass das Zahnsegment den Abhebestift der Blattfeder freigibt. Erst nach der Freigabe des Abhebestiftes erfolgt die Einzugsbewegung des Schlittens.In order to clamp the new form again, the lifting pin must be released again. For this purpose, it is provided according to the invention that the oscillation axis, which carries the toothed segment, is mounted so as to be longitudinally displaceable and that the cam disc carries a cam which interacts with the end of the oscillation axis on the curve side and which displaces it at least at the beginning of the first region of the control curve in such a way that the toothed segment provides the lifting pin the leaf spring releases. Only after the lifting pin has been released does the slide move in.

Das Steuergetriebe umfasst nach einem Merkmal der Erfindung eine Kupplungseinrichtung, über die das Steuergetriebe mit dem vorhandenen motorischen Antrieb der Druckeinrichtung kuppelbar ist. Auf diese Weise kann ein gesonderter Antrieb für den Schlitten entfallen. Die Kupplungseinrichtung ist vorzugsweise als Schlingfederkupplung ausgebildet. Diese ist konstruktiv sehr einfach und deshalb preiswert. Zur Betätigung der Kupplungseinrichtung dient erfindungsgemäss ein Magnetschalter oder dergleichen.According to one feature of the invention, the control gear comprises a coupling device, via which the control gear can be coupled to the existing motor drive of the pressure device. In this way, a separate drive for the carriage can be omitted. The Coupling device is preferably designed as a wrap spring clutch. This is structurally very simple and therefore inexpensive. According to the invention, a magnetic switch or the like is used to actuate the coupling device.

Nach einem weiteren Merkmal der Erfindung weist das Steuergetriebe ein Rastgesperre auf, wobei die Rastungen jeweils bestimmten Zeilenstellungen der Vorschubeinrichtung bzw. des Formulars entsprechen. Die Rastklinke des Rastgesperres ist ebenfalls von dem Magnetschalter betätigbar in der Weise, dass bei Einrücken der Kupplungseinrichtung die Rastklinke ausrastet. Durch Betätigung des Magnetschalters wird also gleichzeitig das Rastgesperre freigegeben und die Kupplung eingerückt, so dass das Steuergetriebe und der damit antriebsverbundene Schlitten die vorgesehene Bewegung ausführt. Durch Inaktivieren des Magnetschalters wird die Kupplung gelöst und das Steuergetriebe durch Einrasten der Rastklinke in einer der vorgesehenen Zeilenstellungen präzise abgestoppt.According to a further feature of the invention, the control gear has a locking mechanism, the locking mechanisms in each case corresponding to certain line positions of the feed device or of the form. The locking pawl of the locking mechanism can also be actuated by the magnetic switch in such a way that the locking pawl disengages when the coupling device is engaged. By actuating the magnetic switch, the locking mechanism is released at the same time and the clutch is engaged, so that the control gear and the carriage connected to it perform the intended movement. By deactivating the magnetic switch, the clutch is released and the control gear is stopped precisely by engaging the pawl in one of the line positions provided.

Zur Steuerung des motorischen Antriebes sowie des Magnetschalters ist erfindungsgemäss eine elektronische Steuereinrichtung vorgesehen, die ihrerseits durch den Signalgeber ansteuerbar ist.To control the motor drive and the magnetic switch, an electronic control device is provided according to the invention, which in turn can be controlled by the signal transmitter.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 eine Explosionsdarstellung einer Druckeinrichtung mit Vorschubeinheit und Steuergetriebe;
  • Fig. 2 eine Seitenansicht der Vorschubeinrichtung in Richtung des Pfeiles 11 in Fig. 1;
  • Fig. 3 eine teilweise geschnittene Ansicht des Steuergetriebes in Richtung des Pfeiles 111 Fig. 1;
  • Fig. 4 das Steuergetriebe gemäss Fig. 3 in einer Seitenansicht in Richtung des Pfeiles IV in Fig.1.
An embodiment of the invention is shown in the drawing and described in more detail below. Show it:
  • Figure 1 is an exploded view of a printing device with feed unit and control gear.
  • FIG. 2 shows a side view of the feed device in the direction of arrow 11 in FIG. 1;
  • Fig. 3 is a partially sectioned view of the control gear in the direction of arrow 111 Fig. 1;
  • 4 shows the control gear according to FIG. 3 in a side view in the direction of arrow IV in FIG. 1.

Die in Fig. 1 dargestellte Druckeinrichtung hat einen im wesentlichen konventionellen Grundaufbau. Zwischen zwei seitlichen Chassiswänden 2 und 4 befindet sich die Formular-Aufnahme 6. Diese wird im vorliegenden Fall im wesentlichen von einer Rückwand 8 sowie der Schreibwalze 10 gebildet. Das Formular liegt mit der zu bedrukkenden Seite gegen die Rückwand 8, die im Bereich der Schreibwalze 10 für den Durchtritt des hier nicht näher dargestellten Druckwerkes durchbrochen ist. Zur genauen Zeilenjustierung des Formulares dient ein Anschlag 12, auf welchem das Formular aufliegt. Dieser Anschlag 12 kann über eine Rasteinrichtung 14 in seiner Höhe verstellt werden, so dass unterschiedliche Zeilenhöhen einstellbar sind. Diese Verstellung des Anschlages 12 braucht hier nicht näher beschrieben zu werden; es lässt sich jedoch erkennen, dass der Vorgang umständlich ist, da jeweils die hier nicht näher dargestellte Abdeckung der Einrichtung entfernt werden muss. Leitbleche 16 dienen zur Erleichterung der Einführung des Formulares in die Aufnahme 6. An den Seitenflächen 2 bzw. 4 können schwenkbare Anschläge 18 befestigt werden, von denen nur einer dargestellt ist. Diese umfassen jeweils um eine Achse 20 schwenkbare Führungsbleche 22, welche in einer eingeschwenkten Lage die Aufnahme 6 seitlich verschliessen, in der dargestellten Lage diese jedoch zur Aufnahme breiterer Formulare offen lassen.The printing device shown in Fig. 1 has an essentially conventional basic structure. The form receptacle 6 is located between two side chassis walls 2 and 4. In the present case, this is essentially formed by a rear wall 8 and the platen roller 10. The form lies with the side to be printed against the rear wall 8, which is broken through in the area of the platen roller 10 for the passage of the printing unit, not shown here. A stop 12 on which the form rests is used for precise line adjustment of the form. The height of this stop 12 can be adjusted via a latching device 14, so that different row heights can be set. This adjustment of the stop 12 need not be described in more detail here; However, it can be seen that the process is cumbersome, since the cover of the device, which is not shown in more detail here, has to be removed. Baffles 16 serve to facilitate the introduction of the form into the receptacle 6. Swiveling stops 18 can be attached to the side surfaces 2 and 4, only one of which is shown. These each comprise guide plates 22 which can be pivoted about an axis 20 and which laterally close the receptacle 6 in a pivoted-in position, but in the position shown leave them open for accommodating wider forms.

Ein in Richtung des Pfeiles 24 verschiebbar gelagerter Schlitten 26 ragt mit seinem oberen Ende in den Bereich der Aufnahme 6. Eine weiter unten genauer beschriebene Klemmung erfasst das Formular, so dass sich dieses mit dem Schlitten 26 verschiebt. Der Antrieb des Schlittens 26 erfolgt über zwei an diesem ausgebildete Zahnstangen 28, 30, in welche jeweils schwingend gelagerte Zahnsegmente 32, 34 eingreifen. Diese Zahnsegmente sind auf einer Schwingachse 36 befestigt, welche in den Seitenwänden 2 und 4 drehbar gelagert und über einen Schwinghebel 38 entsprechend dem Pfeil 40 schwingend angetrieben wird. Die Schwingachse 36 ist ausserdem in Richtung des Pfeiles 42 längs verschiebbar, so dass die Zahnsegmente 32, 34 in den zugeordneten Zahnstangen 28, 30 seitlich verschoben werden, mit diesen aber stets im Eingriff bleiben. Der Antrieb des Schwinghebels 38 erfolgt über das mechanische Steuergetriebe 44, welches seinerseits über die Antriebswelle 46 mit dem Antrieb 48 in Verbindung steht.A carriage 26, which is displaceably mounted in the direction of arrow 24, projects with its upper end into the region of the receptacle 6. A clamp described in more detail below detects the form, so that it moves with the carriage 26. The carriage 26 is driven by two toothed racks 28, 30 formed thereon, in which toothed toothed segments 32, 34 each engage in a swinging manner. These toothed segments are fastened on an oscillation axis 36, which is rotatably mounted in the side walls 2 and 4 and is oscillatingly driven via an oscillation lever 38 in accordance with the arrow 40. The oscillation axis 36 is also longitudinally displaceable in the direction of the arrow 42, so that the toothed segments 32, 34 are laterally displaced in the associated toothed racks 28, 30, but always remain in engagement therewith. The rocker arm 38 is driven via the mechanical control gear 44, which in turn is connected to the drive 48 via the drive shaft 46.

Fig. 2 zeigt in vergrösserter Darstellung den Schlitten 26, welcher auf eine herkömmliche und deshalb nicht näher dargestellte Weise in Richtung des Pfeiles 24 verschiebbar gelagert ist. Die Gabeln 50, von denen in Fig. 2 nur eine dargestellt ist, werden auf einer Verbindungsstange 52 geführt. Der Schlitten 26 nimmt in Fig. 2 seine untere Lage ein, bei der das durch eine gestrichelte Linie dargestellte Formular 54 ganz in die Aufnahme eingezogen ist, so dass das Druckwerk 56 die oberste Zeile drucken kann (Das Formular hat Standardabmessungen, so dass das Führungsblech 22 in seine heruntergeklappte, die Aufnahme 6 seitlich verschliessende Lage geschwenkt sein kann). Beim Zurückschwenken der Zahnsegmente 32 und 34 wird der Schlitten 26 nach oben verschoben, wobei er das Formular 54 mitnimmt. Es ist gründsätzlich möglich, dass das Formular zuerst ganz in die Aufnahme eingezogen wird und beim Ausschieben zeilenweise bedruckt wird.Fig. 2 shows an enlarged view of the carriage 26, which is mounted in a conventional and therefore not shown manner in the direction of arrow 24. The forks 50, only one of which is shown in FIG. 2, are guided on a connecting rod 52. The carriage 26 assumes its lower position in FIG. 2, in which the form 54 represented by a dashed line is completely drawn into the receptacle, so that the printing unit 56 can print the top line (the form has standard dimensions, so that the guide plate 22 can be pivoted into its folded down position 6 which laterally closes the receptacle). When the toothed segments 32 and 34 are pivoted back, the slide 26 is moved upwards, taking the form 54 with it. It is fundamentally possible for the form to be completely drawn into the receptacle first and printed line by line when it is pushed out.

Der Aufbau des Steuergetriebes 44 ist aus den Figuren 3 und 4 zu erkennen. Das gesamte, zwischen zwei Stegwänden 58, 60 aufgenommene Getriebe ist mittels Abstandsbolzen 62, 64 an der Seitenwand 4 befestigt. In das mit der Antriebswelle 46 verbundene Zahnritzel 66 greift ein mit einer Kupplungswelle 68 verbundenes Zahnrad 70 ein. Auf der Kupplungswelle 68 ist eine Schlingfederkupplung 72 angeordnet, welche durch einen Magnetschalter 74 betätigbar ist. Durch die Schlingfederkupplung 72 kann die Kupplungswelle 68 mit dem Zahnrad 76 gekuppelt werden, welches seine Drehbewegung über ein Zwischenzahnrad 78 auf ein weiteres Zahnrad 80 überträgt, welches seinerseits auf der Kurvenscheibenwelle 84 befestigt ist. Die Kurvenscheibenwelle 82 trägt die Kurvenscheibe 84, die mit einer geschlossenen, etwa herzförmigen Steuerkurve 86 versehen ist. In die Steuerkurve 86 greift ein mit dem Schwinghebel 38 verbundener Steuerstift 88 ein. Wie insbesondere Fig. 4 zeigt, weist die Steuerkurve 86 einen ersten Bereich 90 auf, welcher der kontinuierlichen Einzugsbewegung des Schlittens 26 entspricht, sowie einen zweiten Bereich 92, welcher der zeilenweisen Ausschiebebewegung des Schlittens sowie des damit verbundenen Formulars entspricht. Wenn sich die Kurvenscheibe 84 in Fig. 4 in Richtung des Pfeiles 95 dreht, durchläuft der Steuerstift 88 den Bereich 92. Er nimmt dabei nacheinander, ausgehend von der Pos. a die Positionen b, c, d und e ein. Jede dieser Positionen entspricht einer Druckzeile. Position e entspricht gleichzeitig der Anfangsstellung des Schlittens, bei der das Formular entnommen und ein neues eingelegt werden kann. Beim Weiterdrehen der Kurvenscheibe 84 in der gleichen Drehrichtung durchläuft der Steuerstift den Bereich 90, wobei der Schwinghebel 38 wieder in die Pos. a zurückgeschwenkt, das Formular also vollständig eingezogen wird.The structure of the control gear 44 can be seen from Figures 3 and 4. The entire transmission accommodated between two web walls 58, 60 is fastened to the side wall 4 by means of spacer bolts 62, 64. A gearwheel 70 connected to a coupling shaft 68 engages in the pinion 66 connected to the drive shaft 46. A wrap spring clutch 72, which can be actuated by a magnetic switch 74, is arranged on the coupling shaft 68. Through the wrap spring clutch 72, the clutch shaft 68 can be coupled to the gear 76, which rotates about an intermediate gear 78 transmits to another gear 80, which in turn is attached to the cam shaft 84. The cam disk shaft 82 carries the cam disk 84, which is provided with a closed, approximately heart-shaped control cam 86. A control pin 88 connected to the rocker arm 38 engages in the control cam 86. As shown in FIG. 4 in particular, the control cam 86 has a first region 90 which corresponds to the continuous retraction movement of the carriage 26, and a second region 92 which corresponds to the row-by-row push-out movement of the carriage and the associated form. If the cam disk 84 in FIG. 4 rotates in the direction of the arrow 95, the control pin 88 passes through the area 92. It takes the positions b, c, d and e one after the other, starting from the position a. Each of these positions corresponds to a print line. Position e also corresponds to the starting position of the carriage, at which the form can be removed and a new one inserted. When the cam 84 continues to rotate in the same direction of rotation, the control pin passes through the area 90, the rocking lever 38 being pivoted back into position a, that is to say the form is drawn in completely.

Um eine genaue Zeilenpositionierung der Kurvenscheibe 84 sowie des damit verbundenen Schlittens 26 zu gewährleisten, ist ein Klinkengesperre 94 vorgesehen. Auf einem mit dem angetriebenen Teil der Schlingfederkupplung 72 verbundenen Teil 96 ist eine Sperrverzahnung 98 ausgebildet, in die eine Sperrklinke 100 eingreifen kann. Die Sperrklinke 100 ist über einen Hebel 102 um eine Achse 104 drehbar gelagert und wird durch eine Feder 106, welche auf einen mit dem Hebel 102 in Verbindung stehenden Hebel 108 wirkt, in eingerasteter Stellung gehalten (Fig. 4). Die Sperrklinke 100 kann durch den Magnetschalter 74 entgegen der Kraft der Feder 106 ausgerastet werden, so dass das Teil 96 eine Drehbewegung ausführen kann. Die Schlingfederkupplung 72 sowie die Sperrklinke 100 werden gleichzeitig durch den Magnetschalter 74 betätigt derart, dass beim Einkuppeln die Sperrklinke ausgerastet wird. Die Schlingfederkupplung hat eine 4x90° Rastteilung; ein Weiterschalten um 90° entspricht jeweils einer Bewegung des Schwinghebels 38 von einer Position (a, b usw.) zur nächsten, so dass nach einem Umlauf des Teils 96 die Positionen von a bis e durchlaufen werden. Zum Einziehen des Schlittens ist entsprechend eine weitere 90°-Schaltbewegung des Teils 96 erforderlich.To ensure precise line positioning of the cam plate 84 and the slide 26 connected to it, a ratchet mechanism 94 is provided. On a part 96 connected to the driven part of the wrap spring clutch 72, a locking toothing 98 is formed, in which a pawl 100 can engage. The pawl 100 is rotatably mounted about an axis 104 via a lever 102 and is held in the locked position by a spring 106, which acts on a lever 108 connected to the lever 102 (FIG. 4). The pawl 100 can be disengaged by the magnetic switch 74 against the force of the spring 106, so that the part 96 can perform a rotary movement. The wrap spring clutch 72 and the pawl 100 are actuated simultaneously by the magnetic switch 74 such that the pawl is disengaged when the clutch is engaged. The wrap spring clutch has a 4x90 ° locking pitch; switching through 90 ° corresponds in each case to a movement of the rocker arm 38 from one position (a, b, etc.) to the next, so that after a revolution of the part 96, the positions from a to e are run through. Accordingly, a further 90 ° switching movement of the part 96 is required to pull in the slide.

Wie insbesondere Fig. 3 zeigt, ist auf der der Schwingachse 36 zugewandten Seite der Kurvenscheibe 84 ein Nocken 110 angeordnet, welcher mit dem Ende der Schwingachse 36 bzw. dem darauf befestigten, kuppenförmigen ausgebildeten Schwinghebel 38 zusammenwirkt. Dadurch wird die Schwingachse 36 jeweils dann, wenn der Steuerstift 88 den in Fig. 4 mit a bezeichneten Bereich durchläuft, gegen die Kraft der Druckfeder 112 verschoben. Der Bereich a zeichnet sich dadurch aus, dass hier die Steuerkurve konzentrisch zur Kurvenscheibenachse 82 verläuft, so dass der Schwinghebel 38 keine Bewegung macht, sondern in seiner der Pos. e entsprechenden Lage verbleibt. Wie aus Fig. 2 zu erkennen ist, ist am Schlitten 26 eine durch oder mehrere gekröpfte Blattfedern 114 gebildete Klemmung angeordnet. Diese liegen federnd gegen den Schlitten an und dienen zum Festhalten des Formulars 54. Auf jeder Blattfeder ist ein Abhebestift 116 befestigt, welcher durch eine durch die Zahnstangen 28, 30 verlaufende Bohrung bis in eine Zahnlücke 118 ragt. Wenn die Zahnsegmente 32, 34 den Schlitten 26 aus der in Fig. 2 dargestellten unteren Lage nach oben verschieben, gelangt jeweils ein Zahn der Zahnsegmente in die entsprechende Zahnlücke 118 und drückt den Abhebestift 116 nach unten, so dass die Blattfedern 114 in die gestrichelt dargestellte, abgehobene Lage verschoben werden. In dieser Lage ist die Klemmung freigegeben, so dass ein Formular 54 entnommen oder eingelegt werden kann. Durch die anschliessende, vorne beschriebene Verschiebebewegung der Schwingachse 36 werden die Zahnsegmente so weit seitlich verschoben, dass sie die Abhebestifte 116 freigeben und die Blattfedern 114 infolge ihrer eigenen Federkraft wieder ihre Klemmstellung einnehmen, so dass das Formular 54 festgehalten wird. Bei dieser Verschiebebewegung der Zahnsegmente 32, 34 macht der Schlitten 26 noch keine Bewegung, da der Steuerstift 88 den konzentrischen Steuerkurvenbereich a durchläuft, wie vorne beschrieben wurde. Am Ende des Bereiches a gelangt der Nocken 110 wieder ausser Eingriff mit dem Schwinghebel 38, die Schwingachse 36 sowie die darauf angeordneten Zahnsegmente 32, 34 nehmen unter der Wirkung der Druckfeder 112 wieder ihre normale Lage ein. Beim Weiterdrehen der Kurvenscheibe 84 durchläuft der Steuerstift 88 dann den an den Bereich a anschliessenden Bereich 90 der Steuerkurve, so dass der Schwinghebel 38 in Fig. 4 nach rechts schwingt und der Schlitten 26 seine Einzugsbewegung von der Pos. e in die Pos. a durchführt. Anschliessend erfolgt wiederum die dem Bereich 92 der Steuerkurve 86 entsprechende, zeilenweise Ausschiebebewegung des Schlittens mit einem Lösen der Klemmung am Ende dieser Bewegung, wie weiter oben beschrieben, so dass die Einrichtung für eine weitere Druckfolge bereit ist.As shown in FIG. 3 in particular, a cam 110 is arranged on the side of the cam plate 84 which faces the oscillation axis 36 and which cooperates with the end of the oscillation axis 36 or the dome-shaped oscillating lever 38 fastened thereon. As a result, the oscillation axis 36 is displaced against the force of the compression spring 112 each time the control pin 88 passes through the region designated by a in FIG. 4. The area a is characterized in that here the control cam runs concentrically to the cam disk axis 82, so that the rocking lever 38 does not move, but remains in its position corresponding to item e. As can be seen from FIG. 2, a clamp formed by one or more cranked leaf springs 114 is arranged on the slide 26. These rest resiliently against the slide and serve to hold the form 54 in place. A lifting pin 116 is fastened to each leaf spring and projects through a hole running through the toothed racks 28, 30 into a tooth gap 118. When the toothed segments 32, 34 move the slide 26 upward from the lower position shown in FIG. 2, one tooth of each toothed segment reaches the corresponding tooth gap 118 and presses the lifting pin 116 downward, so that the leaf springs 114 are shown in dashed lines , off-the-shelf position. In this position, the clamping is released so that a form 54 can be removed or inserted. As a result of the subsequent displacement movement of the oscillation axis 36 described above, the toothed segments are displaced laterally to such an extent that they release the lifting pins 116 and the leaf springs 114 return to their clamping position due to their own spring force, so that the form 54 is retained. With this sliding movement of the toothed segments 32, 34, the slide 26 does not yet move, since the control pin 88 passes through the concentric control cam region a, as described above. At the end of area a, the cam 110 again disengages from the rocker arm 38, the rocker shaft 36 and the toothed segments 32, 34 arranged thereon return to their normal position under the action of the compression spring 112. When the cam disk 84 continues to rotate, the control pin 88 then passes through the area 90 of the control cam adjoining area a, so that the rocking lever 38 swings to the right in FIG. 4 and the slide 26 carries out its retraction movement from item e to item a . This is then followed in turn by the line-by-line push-out movement of the slide corresponding to the region 92 of the control cam 86 with a release of the clamping at the end of this movement, as described above, so that the device is ready for a further print sequence.

Die Steuerung der gesamten Einrichtung erfolgt in der Weise, dass ein Signalgeber 120, beispielsweise ein mechanischer Fühler oder eine Lichtschranke, meldet, dass ein Formular eingelegt wurde, und ein entsprechendes Startsignal abgibt. Eine elektronische Steuereinrichtung 122 steuert den Druckzyklus durch mehrmalige Bestromung des Antriebes 48 sowie des Magnetschalters 74, der seinerseits die Schlingfederkupplung 72 sowie das Klinkengesperre 94 betätigt. Wie Fig. 1 zeigt, kann der Signalgeber 120 an einem der Leitbleche 16 angeordnet und z.B. als Lichtschranke ausgebildet sein.The entire device is controlled in such a way that a signal generator 120, for example a mechanical sensor or a light barrier, reports that a form has been inserted and emits a corresponding start signal. An electronic control device 122 controls the pressure cycle by repeatedly energizing the drive 48 and the magnetic switch 74, which in turn actuates the wrap spring clutch 72 and the ratchet mechanism 94. As shown in Fig. 1, the signal generator 120 can be arranged on one of the guide plates 16 and e.g. be designed as a light barrier.
