Die Erfindung betrifft eine Vorrichtung zur Herstellung von fadengehefteten Buchblöcken aus einem Stapel flach aneinandergereihter Druckbogen, die zur Bildung von Stichen jeweils durch einen die Falze der Druckbogen von aussen durchsetzenden, entlang der Innenkante der Falze verlaufenden und an einer Austrittsstelle aus den Falzen heraustretenden, doppelsträngig geführten, rechtwinklig zu den Falzen der Druckbogen parallel verlaufende Nähte bildenden Bindefaden aneinandergeheftet sind, und dass zur Bildung einer Naht eine Bindeeinheit vorgesehen ist, welcher jeweils eine den Falz der Druckbogen mit dem Bindefaden von aussen nach innen durchsetzende erste Nähnadel und eine den Bindefaden an der Austrittsstelle aus dem Falz herausziehende zweite Nähnadel zugeordnet sind, wobei der durch die erste Nähnadel zwischen die den Falz bildenden Schenkel eines Druckbogens eingezogene Abschnitt des doppelsträngig geführten Bindefadens von einem die Bindeeinheit durchströmenden Gasstrom erfasst und von der ersten Nähnadel an die zweite Nähnadel transportiert wird.The invention relates to a device for the production of thread-stitched book blocks from a stack of flat printed sheets, each passing through a the folds of the sheet passing through from outside, along the inner edge of the folds extending and emerging at an exit point from the folds, double-stranded out are stitched together at right angles to the folds of the sheet parallel seams forming binder threads, and that for forming a seam, a binding unit is provided, which in each case one of the fold of the sheet with the binding thread from the outside to inside penetrating first sewing needle and the binding thread at the exit point from the fold pulling out second sewing needle are assigned, wherein the drawn through the first sewing needle between the forming the fold legs of a sheet section of the double-stranded binder thread from a binding unit flowing through the gas stream e rfasst and transported from the first sewing needle to the second sewing needle.

Eine Vorrichtung der oben beschriebenen Art offenbart die EP 0 832 758 A1 . Dort sind die in Reihe nebeneinander angeordneten Bindeeinheiten als sog. Blasschiene ausgebildet, deren Herstellung eine hohe Präzision erfordert und nur mit entsprechendem hohem Aufwand durchführbar ist. Insbesondere das Wenden des Werkstückes in die verschiedenen Bearbeitungsstellungen und die schwierige Zugänglichkeit der zur Umformung notwendigen Werkzeuge ist anspruchsvoll.
Darüberhinaus besteht die Blasschiene aus einer Vielzahl sich bei der Herstellung wiederholender Fertigungsschritte.
Wird eine Bindeeinheit der Blasschiene unreparierbar beschädigt, ist die ganze Blasschiene gegen einen hohen Preis auszutauschen.A device of the type described above discloses the EP 0 832 758 A1 , There, the binding units arranged in series next to each other are designed as so-called. Blasschiene, the production of which requires high precision and can only be carried out with a corresponding high expenditure. In particular, the turning of the workpiece in the various processing positions and the difficult accessibility of the necessary tools for forming is demanding.
In addition, the blower rail consists of a variety in the production of repetitive manufacturing steps.
If a binding unit of the blower rail is irreparably damaged, the entire blower rail must be exchanged for a high price.

Daraus hat sich die Aufgabe gestellt, die bei der einstückigen Blasschiene erkannten Nachteile zu eliminieren und eine Vorrichtung zu schaffen, die hinsichtlich Herstellung und Unterhalt bei der Anwendung eines geringeren Aufwandes bedarf.It has the object to eliminate the disadvantages recognized in the one-piece blower rail and to provide a device that requires less production and maintenance in the application of a lower cost.

Erfindungsgemäss wird die Aufgabe dadurch gelöst, dass die die entlang eines Falzes eines Druckbogens in Reihe angeordneten, Stiche bildenden Bindeeinheiten an einer Sockelleiste lösbar befestigt sind.According to the invention the object is achieved in that the arranged along a fold of a sheet in a row, stitches forming binding units are releasably secured to a skirting.

Dadurch lässt sich eine Serienfertigung in kleinen Losgrössen durchführen, die weniger anspruchsvoll ist und hinsichtlich Verwendung der Blasschiene einen einfachen Austausch von Teilen erlaubt.This allows mass production to be carried out in small batch sizes, which is less demanding and allows easy replacement of parts with regard to the use of the blower rail.

Der Verschleissanfälligkeit von betroffenen Teilen der Vorrichtung kann damit gezielt begegnet werden und sie lässt sich reduzieren und kontrollieren.The susceptibility to wear of affected parts of the device can thus be targeted and it can be reduced and controlled.

Vorteilhaft ist die Tragvorrichtung zur gemeinsamen Befestigung der Bindeeinheiten leistenförmig ausgebildet und bietet eine einfache Zugänglichkeit für das Montage- und Servicepersonal.Advantageously, the support device for joint attachment of the binding units is strip-shaped and provides easy accessibility for assembly and service personnel.

Selbstverständlich könnte die zwischen den Bindeeinheiten angeordneten Nadelführungen jeweils mit einer Bindeeinheit fest verbunden sein, jedoch ist es vorteilhaft, dass zwischen den Bindeeinheiten ein Abstand vorgesehen ist, in den die Nadelführung eingelegt wird, sodass sie sich bezüglich ihrer Lage einstellen lässt.Of course, the needle guides arranged between the binding units could each be fixedly connected to a binding unit, but it is advantageous that a distance is provided between the binding units in which the needle guide is inserted so that it can be adjusted with respect to its position.

Vorzugsweise ist die Nadelführung durch jeweils zwei benachbarte Bindeeinheiten auf eine Sockelleiste aufgespannt, die einen Teil der Tragvorrichtung bildet und dieser Stabilität vermittelt.Preferably, the needle guide is clamped by two adjacent binding units on a baseboard, which forms part of the support device and this stability mediates.

Die Sockelleiste wiederum ist zweckmässig mit einer Sattelplatte verbunden, die der rittlingsweisen Auflage eines Druckbogens dient.The skirting in turn is suitably connected to a saddle plate, which serves the rittlingsweise edition of a printed sheet.

Im Sinne einer günstigen Bauweise weist die Sockelleiste eine keilige Aufspannfläche für die Bindeeinheiten auf, die parallel zur Richtung der Nahnadelbewegungen verläuft.In terms of a low cost construction, the baseboard has a wedge-shaped clamping surface for the binding units, which runs parallel to the direction of Nahnadelbewegungen.

Durch eine bis zur Sattelplatte sich erstreckende Nadelführung kann die Abstützung der Nähnadel begünstigt und verlängert werden.By a needle guide extending to the saddle plate, the support of the sewing needle can be favored and extended.

Ein Teilungsfehler zwischen Nähnadeln und verwendeten Vorstechnadeln kann durch eine Verstellmöglichkeit der Nadelführung ausgeglichen werden.A pitch error between sewing needles and Vorstechnadeln used can be compensated by an adjustment of the needle guide.

Anschliessend wird die Erfindung unter Bezugnahme auf die Zeichnung, auf die bezüglich aller in der Beschreibung nicht näher erwähnten Einzelheiten ausdrücklich verwiesen wird, anhand eines Ausführungsbeispiels erläutert. In der Zeichnung zeigen:

Fig. 1 zeigt ausschnittweise eine Ansicht einer Heftvorrichtung 1 einer zur Herstellung von fadengehefteten Buchblöcken verwendeten Vorrichtung (nicht ersichtlich), auch Fadenheftmaschine bezeichnet. In dieser Darstellung ist ein von einer Zuführstation (nicht ersichtlich) in eine Heftstation taktweise angetriebener Heftsattel 2 erkennbar, auf dem ein Druckbogen 3 rittlings aufliegt. Weiterhin ist in Fig. 1 jeweils ein aus einer ersten Nähnadel 4 und einer zweiten Nähnadel 5 gebildetes Nähnadelpaar erkennbar, das zur Bildung von Stichen angeordnet ist, wobei es sich bei der ersten Nähnadel 4 um diejenige handelt, mit der der Faden doppelsträngig durch den üblicherweise vorgestochenen Falz 12 von aussen durchgezogen wird, wozu die Nadelspitze 7 eine Oese 6 aufweist (siehe Fig. 3). Nach dem Einziehen des Fadens 8 wird die erste Nähnadel 4 vorerst soweit zurückgezogen, dass ein seitlich durch eine Bindeeinheit zugeführter Gasstrom eine Schlaufe 9 bildet, die sich über die Position der zweiten Nähnadel 5 erstreckt. Die zweite Nähnadel 5, die über dem Falz 12 des zuvor fadengehefteten Druckbogens 3 von der Schlaufe 9 umgeben ist, zieht den doppelstrangigen Faden 8 durch einen Arbeitshub aus dem Falz 12 hinaus und der bestehende geheftete Buchblock wird um die Dicke eines Druckbogens 3 abgestossen, sodass der nächste Druckbogen 3 geheftet werden kann. Bei diesem Prozedere verlässt auch die erste Nähnadel 4 den Druckbogen 3 und die von der zweiten Nähnadel 5 für einen Stich zuvor gebildete Schlaufe 9 wird durch die letzte Schlaufe 13 hindurchgezogen, sodass sich ein neuer Schlaufenabschnitt an der bestehenden gehefteten Naht 14 bildet. Diese Vorgehensweise wiederholt sich mit jedem, einem Buchblock zum Heften zugeführten Druckbogen 3. Die dazu verwendete Heftvorrichtung 1 besteht aus einem Heftsattel 2 auf den die Druckbogen 3 am Ende eines Zuführweges aufgelegt und durch den Heftsattel 2 in eine Heftstation 16 überführt werden. Der übernächsten Verarbeitungsschritt, nachdem der Falz 12 von innen nach aussen vorgestochen ist, zeigen die Fig. 1 und 2. Die ersten 4 und die zweiten 5 Nähnadeln sind durch den Falz 12 zwischen die Schenkel 17, 18 eines mit den vernähten Druckbogen 3 zu vernähenden Druckbogens 3 eingefahren, wo die Fadenübertragung per Gasstrom von der ersten Nähnadel 4 an die zweite Nähnadel 5 erfolgt. Gut erkennbar ist in Fig. 1 die über den Buchblock sich erstreckende, durch die erste Nähnadel 4 gefertigte Naht 19 und die von der zweiten Nähnadel 5 erzeugte Naht 14, deren zuletzt gebildete Schlaufe 13 von der zweiten Nähnadel 5 durchsetzt ist. Der Heftsattel 2 weist eine vordere 20 und eine hintere Sattelplatte 21 auf, die spitzwinklig angeordnet sind und an denen die Schenkel 17, 18 des Druckbogens 3 anliegen. Die Breite des Heftsattels 2 entspricht wenigstens der Rückenlänge des grössten zu verarbeitenden Druckbogenformats. Der auch als Blasschiene 22 bezeichnete Teil des Heftsattels 2 dient der Nähnadel-, Faden- und Gasstromführung und ist in Fig. 3 in Längserstreckung auszugsweise so dargestellt, dass die Nähnadeln 4, 5 parallel zur Zeichnungsebene erscheinen. Die Blasschiene 22 besteht aus einer Vielzahl von Bindeeinheiten 23, die an einer mit der Sattelplatte 21 fest verschraubten Sockelleiste 24 in Reihe nebeneinander lösbar befestigt sind. Gemäss Fig. 3 werden die Stiche eines Nähzyklusses jeweils von links nach rechts gebildet, wozu jeweils ein Leitungsstutzen 25 auf der rechten Seite der Bindeeinheit 23 zuständig ist. Der Leitungsstutzen 25 ist an eine Gasstromquelle (nicht dargestellt) angeschlossen. Der lose geführte Fadenabschnitt wird in der Bindeeinheit 23 vom durchfliessenden Gasstrom erfasst, wodurch eine nach der rechten Seite sich erstreckende Schlaufe 9 gebildet wird, in die die zweite Nähnadel 5 anschliessend eintaucht. Danach wird die zweite Nähnadel 5 mit dem Faden 8 am Haken 11 aus der Bindeeinheit 23 herausgezogen und weiter vernäht. Der gleiche Nähvorgang kann mit der gleichen Bindeeinheit auch von rechts nach links zur Bildung von Stichen verwendet werden, wozu der benachbarte Leitungsstutzen 26 an der gleichen Bindeeinheit 23 verwendet wird (siehe auch Fig. 6). In Fig. 4 ist mit einem Querschnitt die Blasschiene 22 mit der Sockelleiste 24 sowie eine an dieser angeschraubte Bindeeinheit 23 veranschaulicht. Gleichzeitig ist die Position der ersten Nähnadel 4 in der Bindeeinheit 23 erkennbar. In Fig. 3 ist weiterhin die gemeinsame Befestigung der Bindeeinheiten 23 an der Sockelleiste 24 ersichtlich, wobei zwischen den Bindeeinheiten 23 jeweils ein Spalt bzw. ein Abstand zur Anordnung einer Nadelführung 27 für die erste Nähnadel 4 vorgesehen ist. Die Nadelführung 27 ist auch in den Fig. 4, 5 und 5a veranschaulicht und aufgrund ihrer geringen Ausmasse durch jeweils zwei benachbarte Bindeeinheiten 23 auf die Sockelleiste 24 aufgespannt. Das Aufspannen der Nadelführung 27 und das Befestigen der Bindeeinheiten 23 erfolgt durch jeweils zwei die Sockelleiste 24 durchsetzende Schrauben 28. Die Fig. 5a lässt einen seitlichen Zwischenraum X der Nadelführung 27 in der dafür vorgesehenen Nut zwischen zwei Bindeeinheiten 23 erkennen. Dadurch wird es möglich sein, nach dem Lösen zweier benachbarter Bindeeinheiten 23 die Nadelführung/en zwischen jeweils zwei Bindeeinheiten 23 in Falzrichtung eines Druckbogens 3 zu verstellen. Die Nadelführungen 27 sind an der Führungsoberfläche jeweils mit den Verschleiss mindernden Massnahmen versehen, beispielsweise gehärtet. Die eine Führungsnut 31 aufweisende Nähnadelführung 27 erstreckt sich quer zur Längserstreckung bis an die hintere Sattelplatte 21, in der eine Aussparung 29 für die zweite Nähnadel 5, auch Hakennadel genannt, vorgesehen ist. Die zweite Nähnadel 5 durchsetzt die Bindeeinheit 23 jeweils parallel zur ersten Nähnadel 4, wobei die in einer Reihe angeordneten Nähnadeln 4, 5 eine spitzwinklig zur Senkrechten verlaufende Ebene bilden. Die in Fig. 3 ohne aufgelegten Druckbogen 3 gezeigte Blasschiene 22 stellt die Eingangsöffnung einer Durchtrittsbohrung 30 für die zweite Nähnadel 5 dar, die auch in Fig. 2 gezeigt ist. Fig. 1 shows a detail of a view of a stapling device 1 of a device used for the production of thread-stitched book blocks (not shown), also called thread stitching machine. In this illustration, a stitching saddle 2 cyclically driven by a feed station (not shown) into a stitching station can be seen on which a printing sheet 3 rests astride. Furthermore, in Fig. 1 each one of a first sewing needle 4 and a second sewing needle 5 formed Nähnadelpaar recognizable, which is arranged to form stitches, wherein it is the first sewing needle 4 to that, with the thread through the usually pre-punched seam 12 pulled through the outside double-stranded becomes, for which the needle point 7 an eyelet 6 has (see Fig. 3 ). After the thread 8 has been drawn in, the first sewing needle 4 is initially retracted to such an extent that a gas flow supplied laterally by a binding unit forms a loop 9 which extends beyond the position of the second sewing needle 5. The second sewing needle 5, which is surrounded by the fold 9 over the fold 12 of the previously thread-stitched signature 3, pulls the double-stranded thread 8 out of the fold 12 by a working stroke and the existing stitched book block is repelled by the thickness of a signature 3, so the next sheet 3 can be stapled. In this procedure, also the first sewing needle 4 leaves the printing sheet 3 and the loop 9 previously formed by the second sewing needle 5 for a stitch is pulled through the last loop 13 so that a new loop portion forms on the existing stitched seam 14. This procedure is repeated with each printed sheet 3 fed to a book block for stapling. The stapling device 1 used for this purpose consists of a saddle 2 on which the printed sheets 3 are placed at the end of a feed path and transferred by the saddle 2 into a stapling station 16. The next processing step, after the fold 12 is prepelled from inside to outside, show the Fig. 1 and 2 , The first 4 and the second 5 sewing needles are retracted by the fold 12 between the legs 17, 18 of a printed sheet 3 to be sewn with the sewn printed sheet 3, where the yarn transfer takes place by gas flow from the first sewing needle 4 to the second sewing needle 5. Well recognizable in Fig. 1 the over the book block extending, made by the first sewing needle 4 seam 19 and the seam 14 produced by the second sewing needle 5, the last formed loop 13 is penetrated by the second sewing needle 5. The saddle 2 has a front 20 and a rear saddle plate 21 which are arranged at an acute angle and against which the legs 17, 18 of the printing sheet 3. The width of the binding saddle 2 corresponds at least to the back length of the largest printed sheet format to be processed. The designated as a blow bar 22 part of the saddle 2 is used Nähnadel-, thread and gas flow guide and is in Fig. 3 in the form of longitudinal excerpts, in such a way that the sewing needles 4, 5 appear parallel to the plane of the drawing. The blow bar 22 consists of a plurality of binding units 23, which at one with the fifth wheel plate 21 firmly screwed skirting 24 are secured in series next to each other releasably. According to Fig. 3 The stitches of a Nähzyklusses are each formed from left to right, for which a respective pipe socket 25 on the right side of the binding unit 23 is responsible. The pipe socket 25 is connected to a gas flow source (not shown). The loosely guided thread portion is detected in the binding unit 23 by the flowing gas stream, whereby a to the right side extending loop 9 is formed, in which the second sewing needle 5 is then immersed. Thereafter, the second sewing needle 5 is pulled out with the thread 8 on the hook 11 from the binding unit 23 and further sewn. The same sewing operation can be used with the same binding unit also from right to left to form stitches, to which the adjacent pipe socket 26 is used on the same binding unit 23 (see also Fig. 6 ). In Fig. 4 is with a cross section, the blow bar 22 with the skirting board 24 and a bolted to this binding unit 23 illustrates. At the same time, the position of the first sewing needle 4 in the binding unit 23 can be seen. In Fig. 3 Furthermore, the common attachment of the binding units 23 on the skirting board 24 can be seen, wherein between the binding units 23 each have a gap or a distance to the arrangement of a needle guide 27 is provided for the first sewing needle 4. The needle guide 27 is also in the Fig. 4, 5 and 5a illustrated and spanned due to their small dimensions by two adjacent binding units 23 on the skirting board 24. The clamping of the needle guide 27 and the fastening of the binding units 23 is carried out by two respective the skirting board 24 passing through screws 28. Die Fig. 5a leaves a lateral space X of the needle guide 27 in the space provided between recognize two binding units 23. This will make it possible, after loosening two adjacent binding units 23, to adjust the needle guide (s) between each two binding units 23 in the folding direction of a printed sheet 3. The needle guides 27 are provided on the guide surface in each case with the wear-reducing measures, for example hardened.
