Description

Die Erfindung betrifft einen Sammelhefter für Broschuren mit einer Heftmaschine, einer betriebsmäßig schrittweise mit den Broschuren beschickten Ausgabestation, einer eine Schnittebene definierenden Vorderschnittmesseranordnung zum Beschnitt der Broschuren entlang einer jeweiligen Soll-Schnittlinie und mit Transportmittelkomponenten, welche die Broschuren betriebsmäßig von der Ausgabestation zur Vorderschnittmesseranordnung transportieren.The invention relates to a saddle stitcher stapler having a stapling machine, an output stage progressively loaded with the leaflets, a cutting plane defining front cutting blade assembly for trimming the booklets along a respective desired cutting line and transporting components which operatively transport the booklets from the dispensing station to the front cutting blade assembly.

Derartige Sammelhefter wurden von der Brehmer Buchbindereimaschinen GmbH, Leipzig unter der Typenbezeichnung ST300 vertrieben und sind so konzipiert, dass die Broschuren bis zur erfolgten Heftung und anschließenden Bereitstellung in der Ausgabestation in Längsrichtung der Rücken der Broschuren transportiert und in der Ausgabestation mittels eines Auswerfers an Auslagebänder übergeben werden, welche die Broschuren sodann quer zu ihrer bisherigen Transportrichtung weiterbefördern, und zwar in Richtung auf einen Trimmer, in welchem zunächst ein Vorderkantenschnitt und anschließend ein Kopfschnitt und ein Fußschnitt erfolgt.Such saddle stitchers were sold by Brehmer Buchbindereimaschinen GmbH, Leipzig under the type designation ST300 and are designed so that the brochures transported to the stapling and subsequent provision in the output station in the longitudinal direction of the backs of the brochures and handed over in the output station by means of an ejector to delivery belts which convey the brochures then transversely to their previous direction of transport, in the direction of a trimmer, in which there is first a leading edge cut and then a head cut and a foot cut.

Ein derartiger Sammelhefter ist auch in der EP 0 962 334 A1 offenbart.Such a saddle stitcher is also in the EP 0 962 334 A1 disclosed.

Durch diese Änderung der Transportrichtung wird die Breite der Broschuren zu einem prozessrelevanten geometrischen Parameter, der durch entsprechende Verstellungen der Phasenlagen der von diesem Parameter betroffenen Maschinenkomponenten berücksichtigt wird. Hierdurch entsteht ein nicht unerheblicher Aufwand zur Umrüstung eines Sammelhefters für einen Auftragswechsel, bei dem sich insbesondere auch die Breite der Broschuren ändert.As a result of this change in the transport direction, the width of the brochures becomes a process-relevant geometric parameter, which is taken into account by corresponding adjustments of the phase positions of the machine components affected by this parameter. This results in a considerable effort to convert a saddle stitcher for a job change, in which in particular also changes the width of the brochures.

Der Erfindung liegt daher die Aufgabe zugrunde, einen eingangs genannten Sammelhefter so auszubilden, dass sich der Umrüstaufwand bei einem Auftragswechsel reduziert, bei welchem sich die Breite der Broschuren verändert.The invention is therefore based on the object, a saddle stitcher mentioned above in such a way that the conversion costs reduced in a job change, in which the width of the brochures changed.

Zur Lösung dieser Aufgabe sind Sensoren vorgesehen, welche die Phasenlagen der Heftmaschine und einer der Transportmittelkomponenten definierende Signale abgeben, und eine diese Signale verarbeitende Steuerung, welche die eine der Transportmittelkomponenten derart ansteuert, dass sich bei einem vorbestimmten Phasenwinkel der Heftmaschine die jeweilige Soll-Schnittlinie unabhängig von der Breite der jeweiligen Broschur in der Schnittebene befindet.To solve this problem, sensors are provided which emit the phase positions of the stapler and one of the means of transport components defining signals, and a control processing these signals, which controls one of the transport components such that at a predetermined phase angle of the stapler, the respective target cutting line independently from the width of each brochure in the cutting plane.

Dies erspart bei einem Auftragswechsel, bei dem sich die Breite der Broschuren ändert, eine Verstellung der Phasenlage des Antriebs für die Vorderschnittmesseranordnung und erbringt darüber hinaus den Vorteil, dass sich im Falle eines gemeinsamen Antriebes für die Heftmaschine und die Vorderschnittmesseranordnung ein stets gleichbleibendes Belastungsprofil dieses Antriebes ergibt und dass dieser Antrieb für das spezielle Belastungsprofil ausgelegt werden kann. Damit wird möglichen Funktionsstörungen vorgebeugt und Leistungseinschränkungen entgegengewirkt.This saves on a job change in which changes the width of the brochures, an adjustment of the phase angle of the drive for the front cutting blade assembly and also provides the advantage that in the case of a common drive for the stapler and the Vorderschnittmesseranordnung always consistent load profile of this drive results and that this drive can be designed for the special load profile. This prevents possible malfunctions and counteracts performance restrictions.

Die Merkmale der Erfindung sind nachfolgend unter Bezugnahme auf die beigefügten Zeichnungen dargelegt. Dabei ist ein bevorzugtes Ausführungsbeispiel zugrundegelegt, bei welchem als angesteuerte Transportmittelkomponente ein Auswurfantrieb eines in der Ausgabestation vorgesehenen Broschurenauswerfers vorgesehen ist.The features of the invention are set forth below with reference to the accompanying drawings. In this case, a preferred embodiment is used, in which as the driven transport component, an ejector drive provided in the output station Broschurenauswerfers is provided.

The stitching station 24 in the present exemplary embodiment comprises two stitching heads 26 and a respective one assigned to them, in FIG Fig. 1 unrecognizable Umbieger which bend by means of the stitching heads 26 in the booklets to be stapled 30 staples 27 and that the legs of the wire clamps 27, which have penetrated the brochures 30.

Die nicht dargestellten Umbieger bilden gemeinsam mit den Heftköpfen 26 und nicht dargestellten Vorrichtungen zur Herstellung der Drahtklammern 27 eine Maschinenkomponente in Form einer Heftmaschine 28 (siehe Fig. 2b).The Umbieger not shown together with the stitching heads 26 and not shown devices for producing the wire staples 27, a machine component in the form of a stapler 28 (see Fig. 2b).

Die Ausgabestation 29 umfasst einen in Fig. 2a angedeuteten Broschurenauswerfer 29.2 mit einem Auswerferschwert 29.3 und Auslegebänder 29.1. Das Auswerferschwert 29.3 greift periodisch in den jeweiligen Falzbruch der gehefteten Exemplare 32 ein, hebt diese aus der Transport- und Heftlinie 22 aus und übergibt sie an die Auslegebänder 29.1, mittels welcher die gehefteten Exemplare 32 in Richtung des Pfeils T weiter transportiert werden, und zwar in Richtung auf eine Beschnittvorrichtung 31, in welcher die gehefteten Exemplare 32 zunächst einer in den Figuren 3a und 3b angedeuteten Vorderschnittmesseranordnung 31.1 zugeführt werden, welche eine Schnittebene 31.2 definiert und zum Beschnitt der nachlaufenden Enden der Broschuren 30 entlang einer Soll-Schnittlinie 31.5 vorgesehen ist.The delivery station 29 comprises a brochure ejector 29.2, indicated in FIG. 2a, with an ejector blade 29.3 and delivery belts 29.1. The ejector blade 29.3 periodically intervenes in the respective fold break of the stapled copies 32, lifts them out of the transport and stapling line 22 and transfers them to the delivery slips 29.1, by means of which the stapled copies 32 are transported further in the direction of the arrow T, namely in the direction of a trimming device 31, in which the stapled copies 32 first one in the FIGS. 3a and 3b indicated front cutting blade assembly 31.1 are supplied, which defines a cutting plane 31.2 and is provided for trimming the trailing ends of the brochures 30 along a desired cutting line 31.5.

Zum Betrieb des Borschurenauswerfers 29.2 ist ein reversierender Auswurfantrieb 29.4 vorgesehen, der dem Broschurenauswerfer 29.2, genauer dem Auswerferschwert 29.3, eine periodische Auswurfbewegung einprägt.For the operation of Borschurenauswerfers 29.2 a reversing ejector 29.4 is provided which impresses the Broschurenauswerfer 29.2, more precisely the ejector blade 29.3, a periodic ejection movement.

Von der Heftstation 24 aus stromaufwärts bezüglich der Transportrichtung gemäß Pfeil P ist eine Mess-Station 33 vorgesehen, in welcher die Dicke der zu heftenden Broschuren 30 ermittelt wird.From the stitching station 24 upstream with respect to the transport direction according to the arrow P, a measuring station 33 is provided, in which the thickness of the brochures 30 to be stapled is determined.

Der Stetigförderer 34 ist in vorliegendem Ausführungsbeispiel als endlose betriebsmäßig umlaufende Sammelkette ausgebildet, an welcher Mitnehmer 34.2 angeordnet sind, welche die hierbei rittlings an die Sammelkette übergebenen Signaturen 16, 18, 20 und schließlich die zu heftenden Broschuren 30 vor sich herschieben.The continuous conveyor 34 is formed in the present embodiment as an endless operationally circulating collecting chain, are arranged on which driver 34.2, which in this case astride the collecting chain passed signatures 16, 18, 20 and finally push the books to be stapled 30 in front of him.

Die Fig. 2a gibt ein Schema eines die Heftstation 24 umfassenden Abschnittes des Sammelhefters wieder. In diesem Abschnitt endet ein Transporttrum 34.1 des als Sammelkette ausgebildeten Stetigförderers 34 und der weitere Transport der Broschuren 30 erfolgt schrittweise mittels eines betriebsmäßig oszillierenden Fingerleistensystems 36. Dieses ist in Fig. 2a lediglich schematisch wiedergegeben. Es umfasst eine Ambossleiste 36.1 zum Unterfangen der zu heftenden Broschuren 30 und eine gemeinsam mit der Ambossleiste 36.1 oszillierende Fingerleiste 36.2. An der Fingerleiste 36.2 sind ansteuerbare Finger 36.3 angeordnet. Die Finger 36.3 sind insofern ansteuerbar, als sie in Richtung auf die Ambossleiste 36.1 und in die entgegengesetzte Richtung schwenkbar mittels einer gelenkigen Verbindung 36.6 an der Fingerleiste 36.2 angelenkt, in Schwenkrichtung auf die Ambossleiste 36.1 vorgespannt und unter der Wirkung einer betriebsmäßig mit dem Doppelpfeil in Fig. 2a angedeutete Hubbewegung ausführenden Steuerleiste 36.4 insbesondere von der Ambossleiste 36.1 weg schwenkbar sind. Die Finger 36.3 sind an ihren der Steuerleiste 36.4 zugewandten Enden bevorzugt mit frei drehbaren Rollen 36.5 versehen, welche bei einer Verstellung der Steuerleiste 36.4 in Richtung auf die Fingerleiste 36.2 oder in die entgegengesetzte Richtung an der Steuerleiste 36.4 abrollen.FIG. 2 a shows a diagram of a section of the saddle stitcher comprising the stitching station 24. In this section ends a Transporttrum 34.1 designed as a gathering chain continuous conveyor 34 and the further transport of the brochures 30 is carried out stepwise by means of a operationally oscillating Fingerleistensystems 36. This is shown in Fig. 2a only schematically. It comprises an anvil strip 36.1 for undertaking the brochures 30 to be stapled and a finger bar 36.2 oscillating together with the anvil strip 36.1. At the finger bar 36.2 controllable fingers 36.3 are arranged. The fingers 36.3 are controllable insofar as they are pivoted in the direction of the anvil strip 36.1 and in the opposite direction by means of an articulated connection 36.6 on the finger bar 36.2, biased in the pivoting direction on the anvil strip 36.1 and under the action of a operationally with the double arrow in FIG 2a indicated lifting movement exporting control bar 36.4 in particular from the anvil bar 36.1 pivotally away are. The fingers 36.3 are at their control bar 36.4 facing ends preferably provided with freely rotatable rollers 36.5, which roll in an adjustment of the control bar 36.4 in the direction of the finger bar 36.2 or in the opposite direction on the control bar 36.4.

Für die oszillierende Bewegung des Fingerleistensystems 36 ist dieses an eine Koppel eines Koppelgetriebes 38 angelenkt, welches seinerseits mittels eines Kurbeltriebes 40 angetrieben wird. Die zur Betätigung des Kurbeltriebs 40 und damit für die oszillierende Bewegung des Fingerleistensystems 36 vorgesehenen Antriebsmittel werden beim vorliegenden Ausführungsbeispiel von einem auch zur Betätigung der Heftköpfe 26 vorgesehenen Heftmaschinenantrieb 42 dargestellt (siehe Fig. 2b).For the oscillating movement of the finger strip system 36 this is hinged to a coupling of a linkage 38, which in turn is driven by means of a crank mechanism 40. The drive means provided for actuating the crank mechanism 40 and thus for the oscillating movement of the finger strip system 36 are represented in the present embodiment by a stapler drive 42 which is also provided for actuating the stitching heads 26 (see FIG. 2b).

Der Heftmaschinenantrieb 42 dient darüber hinaus auch dem Antrieb der Anleger 10, 12, 14 über eine diesen gemeinsame Antriebswelle 15 sowie der Beschnittvorrichtung 31 (siehe Fig. 2b).The stapler drive 42 also serves to drive the investors 10, 12, 14 via a common drive shaft 15 and the trimming device 31 (see Fig. 2b).

Jedenfalls in der Strecklage des Kurbeltriebes 40 und wenigstens bis zu einem bestimmten Kurbelwinkel - beim vorliegenden Ausführungsbeispiel von 16 Grad - sind die Ambossleiste 36.1 und die Fingerleiste 36.2 einerseits und das Transporttrum 34.1 des Stetigförderers 34 überlappt, so dass die Ambossleiste 36.1 eine lagegerecht auf dem Transporttrum 34.1 befindliche Broschur 30 unterfangen und die Finger 36.3 der Fingerleiste 36.2 bei abgestellter Steuerleiste 36.4 die Broschur 30 gegen die Ambossleiste 36.1 pressen können. Dies erfolgt bei übereinstimmenden Geschwindigkeiten des Fingerleistensystems 36 und des Stetigförderers 34 - im vorliegenden Ausführungsbeispiel bei einem Kurbelwinkel von 16 Grad, der somit einen Greifpunkt definiert. Die Finger 36.3 bleiben bis zum Erreichen der Decklage des Kurbeltriebes 40 an die übernommene Broschur 30 angepresst. Beim hier erfolgenden Nulldurchgang der Geschwindigkeit des Fingerleistensystems 36 erfolgt sodann eine Ablage der Broschur 30 auf der Transport- und Heftlinie 22 in einem Ablagepunkt.In any case, in the extended position of the crank mechanism 40 and at least up to a certain crank angle - 16 degrees in the present embodiment - the anvil strip 36.1 and the finger bar 36.2 on the one hand and the Transporttrum 34.1 of the continuous conveyor 34 overlaps, so that the anvil strip 36.1 a correct position on the Transporttrum 34.1 located booklet 30 and fingers 36.3 of the finger strip 36.2 can be pressed with the control bar 36.4 off the brochure 30 against the anvil strip 36.1. This is done at matching speeds of the finger strip system 36 and the continuous conveyor 34 - in the present embodiment at a crank angle of 16 degrees, thus defining a gripping point. The fingers 36.3 remain pressed until reaching the top layer of the crank mechanism 40 to the acquired brochure 30. Here then zero crossing of the speed of the finger strip system 36 is then a storage of the brochure 30 on the transport and stitching line 22 in a storage point.

Nach erfolgtem Null-Durchgang der Geschwindigkeit des Fingerleistensystems 36 in der Decklage des Kurbeltriebes 40 kehrt das Fingerleistensystem 36 seine Bewegungsrichtung um und nimmt schließlich wieder eine dem Kurbelwinkel 0 Grad entsprechende überlappte Lage mit dem Transporttrum 34.1 des Stetigförderers 34 ein, das heißt den Startpunkt für einen weiteren Zyklus der oben beschriebenen Art.After zero crossing of the speed of the finger strip system 36 in the top layer of the crank mechanism 40, the finger strip system 36 reverses its direction of movement and finally takes a crank angle 0 degrees corresponding overlapped position with the Transporttrum 34.1 of the continuous conveyor 34, that is the starting point for a another cycle of the type described above.

Das Fingerleistensystem 36 transportiert somit eine vom Stetigförderer 34 übernommene Broschur schrittweise mit einer Schrittlänge, die einer Strecke entspricht, die im Greifpunkt beginnend bis zum Erreichen des Ablagepunktes zurückgelegt wird.The finger strip system 36 thus transports a taken over by the continuous conveyor 34 brochure step by step with a step length corresponding to a distance that is covered in the gripping point beginning to reach the storage point.

Eine in einem Zyklus des Fingerleistensystems 36 vom Stetigförderer 34 übernommene und nach einem ersten Schritt auf der Transport- und Heftlinie 22 abgelegte Broschur 30 wird im nachfolgenden Zyklus erneut vom Fingerleistensystem 36 erfasst und ein weiteres Mal um die genannte Schrittlänge weiter transportiert. Für eine jeweilige Broschur 30 wiederholt sich dieser Vorgang so lange, bis sie nach erfolgter Heftung die Ausgabestation 29 erreicht hat. Hiervon ausgehend werden die Broschuren mittels Transportmitteln der Beschnittvorrichtung 31 zugeführt. Die Transportmittel umfassen jedenfalls den Broschurenauswerfer 29.2 mit einem Aufwurfantrieb 29.4 und eine Trimmerzuführung 31.3.A leaflet 30 taken over by the continuous conveyor 34 in one cycle of the finger strip system 36 and deposited on the transport and stapling line 22 after a first step is again grasped by the finger strip system 36 in the following cycle and transported a further time by the mentioned step length. For a particular brochure 30, this process is repeated until it has reached the output station 29 after stapling. On this basis, the brochures are fed by means of transport of the trimming device 31. In any case, the means of transport comprise the booklet ejector 29.2 with a discharge drive 29.4 and a trimmer feed 31.3.

Nach erfolgtem Ausheben der Broschuren 30 aus der Transport- und Heftlinie 22 erfolgt der weitere Transport der Broschuren 30 zunächst mittels der Auslegebänder 29.1, und zwar quer zur bis dahin durch den Stetigförderer 34 und das Fingerleistensystem 36 festgelegten Transportrichtung. Die Auslegebänder 29.1 übergeben eine jeweilige Broschur der Trimmerzuführung 31.3 (siehe Fig. 2b) welche die Broschuren 30 mit gleichförmiger Geschwindigkeit an der Beschnittvorrichtung 31 vorgesehenen - hier nicht dargestellten - Transport- und Ausrichtbändern übergibt, welche getaktet und mit einer Geschwindigkeit umlaufen, die größer ist als jene der Broschuren 30 in der Trimmerzuführung 31.3 und welche den Rücken einer jeweiligen Broschur 30 so an einem Anschlag 31.4 ausrichten, dass die Soll-Schnittlinie 31.5 in der Schnittebene 31.2 liegt (siehe Fig. 3a, 3b).After completing the lifting of the brochures 30 from the transport and stitching line 22, the further transport of the brochures 30 is first carried out by means of the Auslegebänder 29.1, and that across the previously determined by the continuous conveyor 34 and the finger strip system 36 transport direction. The delivery belts 29.1 hand over a respective brochure of the trimmer supply 31.3 (see FIG. 2b) which delivers the brochures 30 at uniform speed to the trimming device 31 -not shown here-transport and alignment belts which clock and rotate at a speed which is greater than those of the brochures 30 in the trimmer feeder 31.3 and which align the spine of a respective brochure 30 with a stop 31.4 such that the desired cutting line 31.5 lies in the cutting plane 31.2 (see FIG Fig. 3a . 3b ).

Dieser Zustand wird beim Erfindungsgegenstand sowohl beim Beschnitt breiter Broschuren 30 als auch beim Beschnitt schmaler Broschuren 30', d. h. unabhängig von der Broschurenbreite stets bei ein und demselben Phasenwinkel der Heftmaschine 28 erreicht.This state is the subject of the invention both in the trimming of wide brochures 30 as well as the trimming of narrow brochures 30 ', d. H. regardless of the width of the booklet is always achieved at one and the same phase angle of the stapler 28.

Um dies zu erreichen, ist bei der hier zugrundegelegten Ausgestaltung mittels einer Steuerung 48 (siehe Fig. 4) dafür gesorgt, dass die Broschuren 30, 30' abhängig von deren Breite bei unterschiedlichen Phasenwinkeln der Heftmaschine 28 seitens des Auswerferschwertes 29.3 aus der Transport- und Heftlinie 22 ausgehoben werden. Dabei ist der Phasenwinkel der Heftmaschine 28 zum Zeitpunkt des Aushebens einer Broschur 30, 30' aus der Transport - und Heftlinie 22 um so größer je kleiner die Breite der Broschur 30, 30' ist und er wird so gewählt, dass sich bei Erreichen eines bestimmten ersten Phasenwinkels ϕB nach erfolgtem Ausheben der Broschur 30, 30' aus der Transport- und Heftlinie 22 die nachlaufenden Kanten der Broschuren 30, 30' lediglich abhängig von der Breite der von den Broschuren 30, 30' abzutrennenden Streifen 31.6 und von den Geschwindigkeitsverhältnissen der Trimmerzuführung 31.3 und der an der Beschnittvorrichtung 31 vorgesehenen Transport- und Ausrichtbänder im Wesentlichen an ein und demselben Ort befinden, und dass nach Erreichen eines gegenüber dem ersten größeren zweiten Phasenwinkels ϕC die Soll-Schnittlinie 31.5 unabhängig von der Breite der Broschur 30, 30' in der Schnittebene 31.2 liegt (siehe Figuren 3a und 3b).In order to achieve this, in the case of the embodiment based here, by means of a controller 48 (see FIG Fig. 4 ) ensured that the brochures 30, 30 'depending on their width at different phase angles of the stapler 28 on the part of the ejector blade 29.3 from the transport and stapling line 22 are excavated. In this case, the phase angle of the stapler 28 at the time of lifting a brochure 30, 30 'from the transport and stapling line 22 is the larger the smaller the width of the brochure 30, 30' and it is chosen so that upon reaching a certain first phase angle φB after lifting the booklet 30, 30 'from the transport and stapling line 22, the trailing edges of the brochures 30, 30' only depending on the width of the strip 31.6 to be separated from the brochures 30, 30 'and the speed ratios of the trimmer feed 31.3 and provided on the trimming device 31 Transport and Ausrichtbänder are substantially in one and the same location, and that after reaching a relation to the first larger second phase angle φC, the desired cutting line 31.5 regardless of the width of the brochure 30, 30 'in the cutting plane 31.2 (see FIGS. 3a and 3b ).

Zur Realisierung dessen erfolgt eine entsprechende Ansteuerung des Auswurfantriebes 29.4 seitens der Steuerung 48, die zur Abgabe eines entsprechenden Ansteuersignals die von Sensoren 46 abgegebenen Signale verarbeitet, welche die Phasenlagen der Heftmaschine 28, genauer des Heftmaschinenantriebs 42, und des Auswurfantriebs definieren (siehe Fig. 4).To implement this, a corresponding control of the ejector 29.4 takes place by the controller 48, which processes the signals emitted by sensors 46 for outputting a corresponding drive signal, which define the phase positions of the stapler 28, more precisely the stapler drive 42, and the ejector drive (see Fig. 4 ).

Den obigen Darlegungen ist zwar als angesteuerte Transportmittelkomponente der Broschurenauswerfer 29.2 bzw. dessen Auswurfantrieb 29.4 zugrundegelegt, es liegt jedoch im Rahmen der Erfindung, beispielsweise die Trimmerzuführung 31.3 so anzusteuern, dass bei einem vorbestimmten Phasenwinkel der Heftmaschine 28 die Soll-Schnittlinie 31.5 einer jeweiligen Broschur 30, 30' unabhängig von der Breite der Broschüren 30, 30' in der Schnittebene 31.2 liegt.Although the above explanations are taken as the driven transport component of the booklet ejector 29.2 or its ejector drive 29.4, it is within the scope of the invention, for example, to control the trimmer feed 31.3 so that at a predetermined phase angle of the stapler 28 the desired cutting line 31.5 of a respective brochure 30 , 30 'is independent of the width of the leaflets 30, 30' in the cutting plane 31.2.
