Die Erfindung betrifft eine Hefteinrichtung zur Herstellung von Druckerzeugnissen aus heftklammergebundenen Druckprodukten, bestehend aus einer Fördervorrichtung, auf der gefalzte Druckprodukte rittlings einem über der Fördervorrichtung an einem oszillierend angetriebenen Heftschlitten befestigten, zur Bildung von Klammerschenkeln einen Bieger und zum Durchsetzen der Klammerschenkel durch den Falz der Druckprodukte einen Treiber aufweisenden Heftaggregat und einer mit einer an der Fördervorrichtung mit einstellbarem Abstand dem Heftaggregate gegenüberstehenden Umbiegevorrichtung ausgebildeten Heftmaschine zugeführt werden, und einer die Heftdrahtlänge bestimmenden Drahtzuführvorrichtung sowie einer Drahtschneidvorrichtung, die der Heftmaschine zugeordnet sind.The invention relates to a stapling device for the production of printed products from staple-bound printed products, consisting of a conveyor on the folded printed products astride a mounted on the conveyor to an oscillating driven stapling carriage to form staple legs a bender and to enforce the staple legs through the fold of the printed products a stapling unit having a driver and a stapling machine formed with a clinching device at an adjustable distance from the stapling unit, and a stapling wire length-determining wire feeding device and a wire cutting device associated with the stapling machine.

Hefteinrichtungen dieser Art sind bei Sammelheftern bekannt, mit denen unterschiedliche Druckprodukte an einer Sammelstrecke zu einem Druckerzeugnis zusammengeführt und anschliessend am Falz geheftet werden.Staplers of this type are known in saddle stitchers with which different printed products are brought together on a collection line to a printed product and then stapled at the fold.

Beim Sammelhefter "Tempo" von Müller Martini -Prospekt 410/9708- werden die auf einer Fördervorrichtung gesammelten Druckprodukte während dem Transport durch die mitlaufende Heftmaschine geheftet.With the saddle stitcher "Tempo" by Muller Martini -Prospect 410 / 9708-, the printed products collected on a conveyor are stapled during transport by the revolving stapler.

Die vorveröffentlichte DE - A - 197 12 863 offenbart ein Verfahren und eine Vorrichtung zum Bereitstellen, Bearbeiten und Verarbeiten eines Heftdrahtes zum Heften von zu Stapeln aufeinander abgelegten Einzelblättern im flachseitigen Randbereich mittels Haftgerät.The pre-published DE - A - 197 12 863 discloses a method and apparatus for providing, processing and processing a stitching wire for stapling stacked individual sheets in the flat side edge area by means of an adhesive device.

Die vorbekannte US - A - 6 142 353 vermittelt eine Hefteinrichtung eines Sammelhefters für das Heften von rittlings auf einer Sammelkette transportierten mehrblättrigen Druckprodukten.The previously known US Pat. No. 6,142,353 provides a stapler for a saddle stitcher for stapling multi-bladed printed products transported astride a saddlery.

Bei einem anderen, unter das gleiche Heftprinzip fallenden Sammelhefter werden die durch die Fördervorrichtung transportierten Druckprodukte am Förderende von einem anschliessenden Fördersystem übernommen und beschleunigt in die Heftposition versetzt, wo sie im Stillstand geheftet und danach weitertransportiert werden.In another, under the same stapling principle covered saddle stitcher transported by the conveyor printing products are taken over at the end of delivery by a subsequent conveyor system and accelerated in the stapling position, where they stapled at a standstill and then transported on.

Bei einem Trommelsammelhefter werden die Druckprodukte entlang einer Mantellinie einer um eine horizontale Achse drehenden Trommel gefördert und anschliessend im Stillstand an der drehenden Trommel durch eine mitlaufende Heftmaschine geheftet.In a drum collection stapler, the printed products are conveyed along a surface line of a drum rotating about a horizontal axis and then stapled to the rotating drum by a follower stapling machine at standstill.

Die Aufgabe der Erfindung besteht darin, eine Hefteinrichtung zu schaffen, die geeignet ist, Druckerzeugnisse unterschiedlicher Dicke mit hoher Zuverlässigkeit, ohne manuelle Betätigung der Einstellmittel der betroffenen Vorrichtungen einer Hefteinrichtung und ohne Beeinträchtigung der hohen Produktionsleistung herzustellen, auch dann, wenn die Druckprodukte in einer Reihenfolge unregelmässiger Dicke zugeführt werdenThe object of the invention is to provide a stapling device which is capable of printed products of different thickness with high reliability, without manual operation the setting means of the concerned devices of a stapler and without affecting the high production efficiency, even if the printed products are fed in an irregular thickness order

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass die Drahtschneidvorrichtung verstellbar ist und dass die zur Anpassung einer Heftklammer an die Dicke der gebundenen Druckprodukte einstellbare Heftmaschine durch Einstellmittel mit einer eine zur Dickenmessung der Druckprodukte vor der Heftmaschine an der Fördervorrichtung angeordneten Messvorrichtung ausgebildeten Steuerung oder mit einer gespeicherte Daten der Dicke der Druckprodukte verarbeitenden Steuerung verbunden ist.According to the invention the object is achieved in that the wire cutting device is adjustable and that the adjustable stapling to adapt a staple to the thickness of the bound printed products stapler by adjusting means with a arranged to measure the thickness of the printed products in front of the stapler on the conveyor measuring device trained control or with a stored data of the thickness of the printed products processing control is connected.

Es ist vorteilhaft, wenn die Einstellmittel der Heftmaschine und der ihr zugeordneten Vorrichtungen gemeinsam durch eigene, mit der Steuerung verbundene, ortsfeste Antriebsmittel einstell- und verstellbar sind, damit zuverlässig und schnell eine Verstellung vorgenommen werden kann, ohne dass dadurch ein Unterbruch der Produktion entsteht.
Hiervon sind funktionsbezogen gesteuerte Einzelantriebe der Heftmaschine für einen Sammelhefter betroffen.It is advantageous if the setting means of the stapler and its associated devices together by their own, connected to the controller, stationary drive means are adjustable and adjustable so that reliable and fast adjustment can be made without thereby interrupting production.
Of these, functionally controlled individual drives of the stapler for a saddle stitcher are affected.

Es ist zweckmässig, wenn bei einer in der Höhe verstellbaren Fördervorrichtung die Einstellmittel zur Höhenverstellung der Fördervorrichtung mit einem steuerbaren, ortsfesten Antriebsmittel verbunden sind, damit dieser Verstellvorgang gleichzeitig mit anderen gesteuerten Umstellungen vorgenommen werden kann.It is expedient if, in the case of a height-adjustable conveying device, the adjusting means for adjusting the height of the conveying device are connected to a controllable, stationary drive means, so that this adjusting process can be carried out simultaneously with other controlled changes.

Die Einstellungen oder Verstellungen der Einstellmittel sollen vorteilhaft während dem Lauf der Hefteinrichtung bzw. eines Sammelhefters, vorzugsweise vor oder nach einem Heftzyklus erfolgen.The adjustments or adjustments of the adjusting means should advantageously take place during the run of the stapling device or a saddle stitcher, preferably before or after a stapling cycle.

Bei einer Einrichtung mit einer nach der Dicke der Druckerzeugnisse einstellbaren Drahtzuführvorrichtung können Einstellmittel der Drahtzuführvorrichtung durch eine den Heftschlitten parallel zu dessen Bewegungsrichtung durchsetzende Antriebswelle eines Antriebsmittels und jeweils ein einem Heftaggregat zugeordneten, auf der Antriebswelle verschiebbar befestigten Antriebsrad eines Getriebes ausgebildet sein, sodass u.a. flexible Leitungen für die elektrische Energiezufuhr von rasch wechselnden Bewegungen des Heftschlittens verschont bleiben.In a device with a wire feed device which can be adjusted according to the thickness of the printed products, adjusting means of the wire feed device can be formed by a drive shaft of a drive means passing through the stapling carriage parallel to its direction of movement and in each case by a drive wheel of a gearbox which is displaceably mounted on the drive shaft and assigned to a stapling unit Among other things, flexible cables for the electrical energy supply of rapidly changing movements of the stitching carriage are spared.

Es erweist sich als einfache und zuverlässige Bauform, wenn das Getriebe als Winkelgetriebe ausgebildet ist.It proves to be a simple and reliable design when the transmission is designed as an angle gear.

Vorteilhaft ist eine Einrichtung mit einer einen nach der Dicke der Druckerzeugnisse einstellbaren Messerhalter aufweisenden Drahtschneidvorrichtung durch Einstellmittel ausgebildet, die einen an dem Messerhalter in eine schräg zur Bewegungsrichtung des Heftschlittens verlaufende Führungsbahn eingreifenden Mitnehmerstift aufweisen, der durch eine höhenverstellbare Führungsleiste mit einem aus wenigstens einem drehwinkelgesteuerten Elektromotor bestehenden Antriebsmittel verbunden ist.Advantageously, a device comprising a wire cutting device having a knife holder having adjustable thickness according to the printed products is formed by adjusting means having a driving pin engaging the blade holder in a guideway extending obliquely to the direction of movement of the stitching carriage, which by a height adjustable guide bar with one of at least one rotational angle controlled electric motor existing drive means is connected.

Dadurch wird ermöglicht, dass eine auf Antriebsnocken der Messerhalter mehrerer Heftaggregate einwirkende, an dem Heftschlitten befestigte Nockenleiste in einer Führungskulisse der Führungsleiste oszillierend antreibbar ist.This makes it possible for a cam strip, which acts on drive cams of the knife holders of a plurality of stitching units and is fastened to the stitching carriage, to be driven to oscillate in a guide slot of the guide strip.

Alternativ kann bei einer Einrichtung mit einer einen nach der Dicke der Druckerzeugnisse einstellbaren Messerhalter aufweisenden Drahtschneidvorrichtung, ein an dem Messerhalter in eine schräg zur Bewegungsrichtung des Heftschlittens verlaufende Führungsbahn eingreifender Mitnehmerstift über ein Hebelvorgelege mit einem Antriebsmittel verbunden sein.Alternatively, in the case of a device having a wire cutting device having a knife holder which is adjustable according to the thickness of the printed products, a driving pin engaging the blade holder in a guide track running obliquely to the direction of movement of the stitching carriage can be connected to a drive means via a lever countershaft.

Zweckmässig kann das als drehwinkelgesteuerter Elektromotor ausgebildete Antriebsmittel mit einer den Heftschlitten parallel zu dessen Bewegungsrichtung durchsetzenden Welle antriebsverbunden und an der Welle jeweils ein mit einem eine Nockenleiste betätigenden Lenker verbundener Hebel befestigt sein.Appropriately, designed as a rotation angle controlled electric motor drive means with a stapling carriage in parallel drivingly connected to the shaft passing through its direction of movement and to be attached to the shaft in each case a lever connected to a handlebar which actuates a cam bar.

Bei einer erfindungsgemässen Einrichtung, mit einer nach der Dicke der Druckerzeugnisse einstellbaren Umbiegevorrichtung, die an einem verstellbaren Umbiegerträger wenigstens einen befestigten Umbiegerblock aufweist, können die Einstellmittel für die Umbiegevorrichtung der Einfachheit halber durch ein Getriebe mit einer Antriebswelle eines ortsfesten, drehwinkelgesteuerten Elektromotors verbunden sein.In an inventive device, with an adjustable according to the thickness of the printed products Umbiegevorrichtung having an adjustable Umbiegerträger at least one fixed Umbiegerblock, the adjustment means for Umbiegevorrichtung can be connected for simplicity by a gear with a drive shaft of a stationary, rotational angle controlled electric motor.

Der Elektromotor kann über einen Antriebsregler mit einem bestimmbaren begrenzten Drehmoment angesteuert werden. Entsteht durch ein zu dickes Druckerzeugnis eine Ueberlast, die zu Schäden führen würde, so wirkt der Elektromotor wie eine Feder und gibt der Ueberlast nach.The electric motor can be controlled via a drive controller with a determinable limited torque. If too much pressure builds up an overload that would cause damage, the electric motor acts as a spring and releases the overload.

Diesbezüglich ist es zweckdienlich, wenn die Einstellmittel für die Umbiegevorrichtung ein an einer stationären Zahnstange bewegliches, mit dem Umbiegeträger antriebsverbundenes Zahnsegment aufweisen, das mit einem an der Antriebswelle eines ortsfesten, drehwinkelgesteuerten Elektromotors angeordneten Hebelarm gekuppelt ist.In this regard, it is expedient if the adjustment means for the clincher device comprise a toothed rack movable on a stationary rack and drivingly connected to the clincher, which is coupled to a lever arm arranged on the drive shaft of a fixed rotary-angle-controlled electric motor.

Bewährterweise kann die Antriebswelle durch eine den Heftschlitten in Bewegungsrichtung durchsetzende, verschiebbare und drehmomentübertragende Wellen-Nabenverbindung mit dem Hebelarm verbunden sein.Tried-and-tested, the drive shaft can be connected to the lever arm by a sliding and torque-transmitting shaft-hub connection which passes through the stitching carriage in the direction of movement.

Bei einer bezüglich Höhe an die Dicke der zu heftenden Druckerzeugnisse anpassbaren Fördervorrichtung, die eine Kettenführung für wenigstens eine umlaufende Gliederkette aufweist, an welcher Einzelteile einer dachförmigen Auflage befestigt sind, ist es vorteilhaft, wenn die Kettenführung nach unten sich erstreckende Heber aufweist, die durch Hebelgetriebe mit der Antriebswelle verbunden sind.In terms of height to the thickness of the printing products to be stapled customizable conveyor, the chain guide for at least one circumferential link chain, to which individual parts of a roof-shaped support are attached, it is advantageous if the chain guide downwardly extending lifter has, which are connected by lever gear to the drive shaft.

Als Antriebsmittel der einzelnen Vorrichtungen sind drehwinkelgesteuerte Elektromotoren, auch Servomotoren bezeichnet, vorgesehen.As drive means of the individual devices are rotational angle controlled electric motors, also called servomotors provided.

Fig. 1 vermittelt auszugsweise einen Sammelhefter im Heftbereich, wo eine Hefteinrichtung 1 an einer Fördervorrichtung 2 angeordnet ist. Auf der Fördervorrichtung 2 werden durch an einem Zugmittel mit sattelförmiger Auflage 3 befestigten Mitnehmern 4 rittlings aufliegende Druckprodukte bzw. zu Druckerzeugnissen 5 gesammelte Druckprodukte in Förderrichtung F der Hefteinrichtung 1 zugeführt, wo sie durch die mitlaufende Heftmaschine am Falz geheftet werden. Die Heftmaschine besteht aus zwei Heftaggregaten 6, 7 und jeweils einem letzteren zugeordneten Umbiegeblock 8, 9 einer Umbiegevorrichtung 10, die alle an einem entlang der Fördervorrichtung 2 oszillierend angetriebenen Heftschlitten 11 befestigt sind. Die Hefteinrichtung 1 arbeitet nach dem Maschinentakt des Sammelhefters. Der Heftschlitten 11 ist an zwei mit einem Maschinengestell 12 verbundenen Stangen 13, 14 geführt.
Die Funktionsweise der Heftaggregate 6, 7 ist in der CH - A - 549 443 beschrieben und wird hier im Rahmen des von der vorliegenden Erfindung betroffenen Umfangs erläutert. Der Heftdraht 15 wird den Heftaggregaten 6, 7, eingespannt zwischen zwei Reibrädern 16, 17 über eine Drahtführung 18 der verlangten Drahtabschnittslänge entsprechend einer Heftklammergrösse zugeführt. Den Antrieb der Reibräder 16, 17 übernehmen zwei kämmende Zahnräder 19, 20, die mit den Reibrädern 16, 17 fest verbunden sind (siehe Fig. 7).
Um die Drahtabschnittslänge für die Heftklammern, die in Fig. 5 dargestellt sind, variieren zu können, bedarf es eines drehwinkelsteuerbaren, ortsfest angeordneten Elektromotors 21 (ersichtlich in Fig. 2), der einerseits mit einem der Reibräder 19, 20 und andererseits mit einer Steuerung 22 zur Einstellung des Elektromotors 21 verbunden ist. Mit einer solchen Lösung kann auch noch vermieden werden, dass die Kabel für die dem Elektromotor 21 zugeführte Energie keinen verschleissfördernden Bewegungen der Hefteinrichtung 1 ausgesetzt sind. Betroffen davon sind die konstruktive Ausführung des Heftschlittens 11 und die erforderlichen Einstellmittel. Hierzu ist im Folgenden vorgeschlagen, dass der Elektromotor 21 mit dem Maschinengestell 12 verbunden ist und an der Antriebswelle 23, die den Heftschlitten 11 parallel zu dessen Bewegung durchsetzt, ein jedem Heftaggregat 6, 7 zugeordnetes Kegelrad 24, 25 aufweist, welches mit einem Antriebskegelrad 26, 27 des Heftaggregats 6, 7 ein Kegelradgetriebe 28, 29 bildet, wobei sich das Antriebskegelrad 26, 27 jeweils auf der Welle 30 des Reibrades 17 befindet (siehe Fig. 3). Die Welle 30, beispielsweise eine Vielkeil- oder Polygonwelle, weist für den Antrieb der Kegelräder 24, 25 einen formschlüssigen Querschnitt auf, sodass die Kegelräder 24, 25 darauf verschiebbar sind. Die Welle 30 ist in Lagerböcken 31, 32 der mit dem Heftschlitten 11 fest verbundenen Heftaggregate 6, 7 abgestützt und die Kegelräder 24, 25 sind in den Lagerböcken 31, 32 wälzgelagert. Der Heftschlitten 11 weist Seitenwände auf, von denen die dem Elektromotor 21 zugewandte von der Welle 30 mit Spiel durchsetzt wird. Alternativ könnten die Lagerböcke 31, 32 auch am Heftschlitten 11 befestigt sein. Fig. 1 extracts extracts a saddle stitcher in the stapling area, where a stapler 1 is arranged on a conveyor device 2. On the conveyor 2 are mounted on a traction device with saddle-shaped support 3 drivers 4 astride printed products or printed products 5 collected printed products in the conveying direction F of the stapler 1 fed where they are stapled by the follower stapler at the fold. The stapling machine consists of two stapling units 6, 7 and each associated with a latter Umbiegeblock 8, 9 a Umbiegevorrichtung 10, which are all attached to a driven along the conveyor 2 oscillating stapling carriage 11. The stapler 1 operates after the machine cycle of the saddle stitcher. The stitching carriage 11 is guided on two rods 13, 14 connected to a machine frame 12.
The operation of the stitching units 6, 7 is in the CH - A - 549 443 and is explained here within the scope of the present invention. The stapling wire 15 is the stapling units 6, 7, clamped between two friction wheels 16, 17 fed via a wire guide 18 of the required wire section length corresponding to a staple size. The drive of the friction wheels 16, 17 take two meshing gears 19, 20 which are fixedly connected to the friction wheels 16, 17 (see Fig. 7 ).
To adjust the wire section length for the staples used in Fig. 5 are shown, to vary, it requires a drehwinkelsteuerbaren, stationarily arranged electric motor 21 (see in FIG Fig. 2 ), which is connected on the one hand with one of the friction wheels 19, 20 and on the other hand with a controller 22 for adjusting the electric motor 21. With such a solution it can also be avoided that the cables for the energy supplied to the electric motor 21 are not exposed to any wear-promoting movements of the stapler 1. Affected by this are the structural design of the stitching carriage 11 and the required adjustment. For this purpose, it is proposed below that the electric motor 21 is connected to the machine frame 12 and on the drive shaft 23, which passes through the stapling carriage 11 parallel to the movement, a each stitching unit 6, 7 associated bevel gear 24, 25, which with a drive bevel gear 26th , 27 of the stitching unit 6, 7, a bevel gear 28, 29 forms, wherein the drive bevel gear 26, 27 respectively on the shaft 30 of the friction wheel 17 is located (see Fig. 3 ). The shaft 30, for example a splined or polygonal shaft, has a form-fitting cross-section for driving the bevel gears 24, 25, so that the bevel gears 24, 25 are displaceable thereon. The shaft 30 is supported in bearing blocks 31, 32 of the stapling carriage 11 firmly connected stitching units 6, 7 and the bevel gears 24, 25 are roller bearings in the bearing blocks 31, 32. The stapling carriage 11 has side walls, of which the electric motor 21 facing the shaft 30 is interspersed with clearance. Alternatively, the bearing blocks 31, 32 could also be fastened to the stapling carriage 11.

Um eine symmetrische Heftklammer 33 bilden zu können, wie in Fig. 5 dargestellt, bedarf es einer regelmässigen Verteilung des dazu benötigten Drahtabschnittes, dessen Länge durch den Drahtvorschub der Drahtzuführvorrichtung bestimmt wird.
Der für eine Heftklammer 33 dem aus Bieger 35 und Treiber 36 gebildeten Heftkopf 34 zugeführte Drahtabschnitt endet an einer in Drahtzuführrichtung vor dem Heftkopf 34 angeordneten Drahtschneidvorrichtung 38. Der zu einer Heftklammer 33 zu verformende Drahtabschnitt ist auf den Bieger 35 gleichmässig verteilt, so dass eine Heftklammer 33 mit gleich langen Schenkeln 39 entsteht. Aufgrund der unterschiedlichen Grössen einer Heftklammer 33 ist die Drahtschneidvorrichtung 38 an die Heftklammergrösse anzupassen, derart, dass der Drahtabschnitt gleichmässig verteilt unter dem Bieger zu liegen kommt. Daran ist auch ein beweglicher Greifer 40 am Heftkopf 34 des Heftaggregates 6, 7 beteiligt, der den Drahtabschnitt festhält und für das Biegen positioniert. Die Drahtschneidvorrichtung 38 besteht aus einem Messerhalter 41 mit einer Drahtdurchführung 42, an deren hinteren Ende ein mit der Rückzugbewegung des Treibers 36 antriebsverbundenes Messer 43 vorgesehen ist, welches den Drahtabschnitt mit Hilfe der Drahtdurchführung 42 als Gegenmesser trennt.In order to form a symmetrical staple 33, as in Fig. 5 shown, it requires a regular distribution of the required wire section whose length is determined by the wire feed of the wire feeder.
The for a staple 33 to the stapling head 34 formed from bender 35 and driver 36 supplied wire ends at a Drahtzuführrichtung before the stapling head 34 arranged wire cutting device 38. The staple to be deformed 33 a wire section is evenly distributed on the bender 35, so that a staple 33 with equal legs 39 is formed. Due to the different sizes of a staple 33, the wire cutting device 38 is adapted to the staple size, such that the wire section comes to lie evenly distributed under the bender. This is also a movable gripper 40 on the stapling head 34 of the stitching unit 6, 7 involved, which holds the wire section and positioned for bending. The wire cutting device 38 consists of a knife holder 41 with a wire feedthrough 42, at the rear end of which a drive 43 connected to the retraction movement of the driver 36 is provided, which separates the wire section with the aid of the wire feedthrough 42 as counter knife.

Damit der Drahtabschnitt gleichmässig auf den Heftkopf 34 verteilt wird, wird entsprechend dem vor- resp. nachgeschobenen Drahtende das Messergehäuse 41 so versetzt, dass nach dem Trennschnitt durch das Messer 43 der vom Greifer 40 erfasste abgeschnittene Drahtabschnitt die Heftposition im Heftkopf einnimmt. Zur Durchführung des Trennvorgangs für Heftklammern mit unterschiedlicher Drahtabschnittslänge ist der Messerhalter 41 durch eine schräg nach oben verlaufende Führungsbahn 44 ausgebildet, in die ein Mitnehmerstift 45 eingreift, der an einem Schieber 46 befestigt ist. Gemäss den Fig. 4 und 7 befindet sich der Messerhalter 41 in der Stellung für kürzeste Drahtabschnitte. Der Schieber 46 wiederum ist als Platte ausgebildet und allseitig geführt. An der Rückseite weist der Schieber 46 einen Antriebsnocken 47 auf, der in eine Nockenleiste 48 eingreift, welche die Schieber 46 zweier Messerhalter 41 verbindet. Die Enden der Nockenleiste 48 bilden Arme 49, die an den freien Enden in eine schlitzartige Führungskulisse 51 einer Führungsleiste 52 ragende frei drehbare Führungsrollen 50 aufweisen. Die Führungsleiste 52 erstreckt sich unterhalb der Heftaggregate 6, 7 und die Führungskulisse 51 weist eine Länge von wenigstens der Weglänge des Heftschlittens 11 auf. An den Enden ist die Führungsleiste 52 an jeweils einem Support 53 befestigt, der ein Innengewinde für eine Gewindespindel 54 aufweist. Die zur Höhenverstellung der Führungsleiste 52 vorgesehenen Gewindespindeln 54 lagern in einem am Maschinengestell 12 befestigten Lagerbock 55 und sind mit einem ortsfest angeordneten Elektromotor 56 antriebsverbunden. Je nach Dicke der zu heftenden Druckerzeugnisse 5 werden die Messerhalter 41 der Heftaggregate 6, 7 über die Elektromotoren 56 durch die Steuerung 22 verstellt bzw. an die Dicke des zu heftenden Druckerzeugnisses 5 angepasst. Eine Aenderung der Höhe der Führungsleiste 52 erfolgt vor oder nach dem Heftvorgang eines Druckerzeugnisses ohne dass dadurch am Maschinentakt eine Verzögerung eintritt. Mit 5' ist übrigens in Fig. 1 ein geheftetes Druckerzeugnis dargestellt, das anschliessend von der Auflage 3 genommen wird.So that the wire section is uniformly distributed on the stapling head 34, is corresponding to the pre resp. nachgeschobenen wire end the knife housing 41 so offset that after the separation cut by the knife 43 of the gripper 40 detected cut wire section occupies the stapling position in the stapling head. To carry out the separation process for staples with different wire section length of the knife holder 41 is formed by an obliquely upwardly extending guide rail 44, in which a driving pin 45 engages, which is fixed to a slider 46. According to the Fig. 4 and 7 the knife holder 41 is in the position for shortest wire sections. The slider 46 in turn is formed as a plate and guided on all sides. At the back of the slider 46 has a drive cam 47 which engages in a cam bar 48 which connects the slide 46 of two knife holder 41. The ends of the cam bar 48 form arms 49, which at the free ends in a slot-like guide slot 51 of a guide rail 52 projecting freely rotatable guide rollers 50 have. The guide strip 52 extends below the stitching units 6, 7 and the guide slot 51 has a length of at least the path length of the stitching carriage 11. At the ends of the guide rail 52 is attached to a respective support 53 having an internal thread for a threaded spindle 54. The provided for height adjustment of the guide rail 52 threaded spindles 54 store in one attached to the machine frame 12 bearing block 55 and are drivingly connected to a fixedly arranged electric motor 56. Depending on the thickness of the printed products 5 to be stapled, the knife holders 41 of the stapling units 6, 7 are adjusted by the electric motors 56 by the controller 22 or adapted to the thickness of the printed product 5 to be stapled. A change in the height of the guide rail 52 is carried out before or after the stapling process of a printed product without causing a delay on the machine cycle. By the way, with 5 'is in Fig. 1 a stapled printed product shown, which is then taken from the support 3.

Eine alternative Ausführung der Einstellmittel bei einem Messerhalter 41 besteht darin, dass der in eine schräg nach oben verlaufende Führungsbahn 44 eingreifende Mitnehmerstift 45 über ein Hebelvorgelege 56 mit einem ortsfesten Elektromotor 57 antriebsverbunden ist (siehe Fig. 12 und 13), wobei die Antriebswelle 58 des Hebelvorgeleges 56 wiederum formschlüssig ausgebildet sein kann und darauf am Ende des Heftschlittens 11 jeweils ein einarmiger Hebel 59 verschiebbar festsitzen kann. Mit dem einarmigen Hebel 59 ist ein Lenker 60 verbunden, der anderenends -wie schon gemäss Fig. 4- an einer Nockenleiste 48 angelenkt ist. Die Nockenleiste 48 ist ihrerseits höhenverstellbar in einer Führung 93 angeordnet.An alternative embodiment of the adjustment means in a knife holder 41 is that the driving pin 45 engaging in an obliquely upward guide track 44 is drive-connected via a lever countershaft 56 to a fixed electric motor 57 (see FIG FIGS. 12 and 13 ), wherein the drive shaft 58 of the Hebelvorgeleges 56 may in turn be formed positively and thereon at the end of the stitching carriage 11 each have a one-armed lever 59 slidably stuck. With the one-armed lever 59, a handlebar 60 is connected, the other end - as already described Fig. 4 - Is hinged to a cam bar 48. The cam bar 48 is in turn arranged vertically adjustable in a guide 93.

Die Umbiegevorrichtung 10 besteht aus zwei Umbiegeblöcken 8, 9, die gemeinsam am Heftschlitten 11 entsprechend dem vorkommenden Dickenunterschied der Druckerzeugnisse 5 gegenüber einem Heftkopf 34 durch einen Umbiegeträger 61 in der Höhe einstell- und verstellbar sind. Der Umbiegeträger 61 ist beispielsweise an einem am Heftschlitten 11 befestigten Keil 62 senkrecht geführt und mittels Schrauben 63, die jeweils einen senkrechten Schlitz durchsetzen, am Heftschlitten 11 gehalten.
Die Einstellung der Höhe der Umbiegerblöcke 8, 9 erfolgt von einem drehwinkelgesteuerten Elektromotor 64 aus, der ortsfest am Maschinengestell 12 befestigt ist. Dieser Elektromotor 64 besitzt eine Antriebswelle 65, die etwa die Breite des Heftschlittens 11 und dessen Hub zum Heften aufweist. Die Antriebswelle 65 ist im Heftschlitten 11 an zwei beabstandeten Versteifungsrippen 66 gelagert. Zwischen den Versteifungsrippen 66 sitzt eine als verschiebbare und drehmomentübertragende Wellen-Nabenverbindung ausgebildete Drehmoment-Kugelbüchse 67, die die Drehbewegung der Antriebswelle 65 auf eine an der Antriebswelle 65 gelagerte, sich mit dem Heftschlitten 11 bewegende Muffe 68 überträgt. Die Muffe 68 und die Antriebswelle 65 sind gemeinsam durch Kugellager in den Versteifungsrippen 66 gelagert. An den Enden der Muffe 66 ist jeweils ein Klemmhebel 69 befestigt. Dieser durch den Elektromotor 64 und die Antriebswelle 65 schwenkbare Klemmhebel 69 verbindet durch eine Stange 70 ein an einer parallelen Welle 71 lagerndes Zahnsegment 72, das mit einer am Heftschlitten 11 befestigten Zahnstange 73 kämmt. Durch die Bewegungen der Antriebswelle 65 wird die Welle 71, die durch Lagerböcke 74 mit dem Umbiegerträger 61 verbunden ist, und der Umbiegerträger 61 auf ein gewähltes Mass, das etwa einem Dickenunterschied zweier Druckerzeugnisse 5 entspricht, angehoben oder abgesenkt. Weiterhin weisen die Fig. 8 bis 10 auf eine Umbiegevorrichtung 10 hin, mit der das Schliessen des Heftdrahtes zur Heftklammer über schwenkbare Flügel (nicht ersichtlich) erfolgt.The adjusting means of arranged on the stitching carriage 11 Umbiegevorrichtung 10 show the Fig. 2 . 8, 9 and 10 , The Umbiegevorrichtung 10 consists of two Umbiegeblöcken 8, 9, together on the stitching carriage 11 in accordance with the occurring thickness difference of the printed products 5 with respect to a stapling head 34 by a Umbiegeträger 61 in the height adjustable and are adjustable. The Umbiegeträger 61 is guided vertically, for example, on a fixed to the stitching carriage 11 wedge 62 and held by screws 63, each passing through a vertical slot on the stitching carriage 11.
