Description

Die vorliegende Erfindung betrifft eine Vorrichtung nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren nach dem Oberbegriff des Anspruchs 8.The present invention relates to a device according to the preamble of claim 1 and a method according to the preamble of claim 8.

In einer Buchdeckenmaschine mit horizontalem Verarbeitungsprinzip [ Liebau, Heinze; Industrielle Buchbinderei; Verlag Beruf und Schule, 1997; S.: 399ff ] werden Deckelpappen und eine Rückeneinlage aus Karton oder Pappe passgerecht mit den mit Klebstoff versehenen Bezugsnutzen in einer Anrolleinrichtung vereinigt. Eine gattungsgemäße Buchdeckenmaschine ist außerdem in der DE 100 57 599 A1 dargestellt und beschrieben. Die Deckelpappen werden aus einem Pappenmagazin ausgeschoben und gemeinsam mit der Rückeneinlage an Führungsschienen seitlich ausgerichtet der Anrolleinrichtung zugeführt. Synchron zur Pappenzuführung wird der Bezugsnutzen über einen Nutzenzylinder in die Anrollebene gebracht. Die überstehenden Kanten der Buchdecke werden anschließend in hintereinander liegenden Arbeitsstationen entweder im fließenden Durchlauf oder jeweils im Stillstand eingeschlagen, i.d.R. erst die an Kopf und Fuß überstehenden Kanten, und nach dem Eckeneinziehen an den Seiten. Abschließend werden die Buchdecken zwischen Presswalzen einer Andrückvorrichtung geführt zum Anreiben der Pappenteile auf den Bezugsnutzen. In einer Auslage gelangen die fertigen Buchdecken als Stapel über einen Rollentisch zur manuellen Abnahme.In a case machine with a horizontal processing principle [ Liebau, Heinze; industrial bookbinding; Verlag Berufs und Schule, 1997; p.: 399ff ] Cardboard covers and a spine insert made of cardboard or paperboard are combined with the cover blanks provided with adhesive in a rolling device. A generic case machine is also in the DE 100 57 599 A1 shown and described. The cardboard covers are ejected from a cardboard magazine and, together with the spine insert, aligned laterally on guide rails and fed to the rolling device. Synchronously to the cardboard feed, the reference blank is brought into the roll-on level via a blank cylinder. The protruding edges of the book cover are then folded in consecutive workstations either continuously or at a standstill, usually first the protruding edges at the top and bottom, and after the corners have been folded in on the sides. Finally, the book covers are guided between the press rollers of a pressing device to rub the cardboard parts onto the reference panel. In a delivery, the finished book covers are stacked on a roller table for manual removal.

Derartige Buchdeckenmaschinen dienen der Massenproduktion von identischen Buchdecken bzw. Schachteldecken in hoher Produktionsleistung. Die ununterbrochene Herstellung von verschiedenen Buch- oder Schachteldecken ist möglich, wenn diese das gleiche Format, d.h. die gleichen Abmessungen hinsichtlich aufgeschlagene Breite, Höhe, Deckelbreite und Rückeneinlagenbreite aufweisen und die zugeführten Bezugsnuten von gleichem Format aber lediglich unterschiedlichem Druckinhalt sind. Die bekannten Buchdeckenmaschinen werden also stets für ein bestimmtes Deckenformat fest eingerichtet.Such book cover machines are used for the mass production of identical book covers or box covers in high production output. The uninterrupted production of different book or box covers is possible if they have the same format, ie the same dimensions in terms of open width, height, cover width and spine width and the supplied reference grooves of the same format but only different print content. The known book cover machines are always set up for a specific cover format.

Bei einem Formatwechsel wird im Stillstand der Buchdeckenmaschine auf die neuen Abmessungen umgestellt. Obwohl mittlerweile in den gattungsgemäßen Buchdeckenmaschinen die wesentlichen Umstellvorgänge durch motorische Verstellachssysteme über eine zentrale Steuerungseinrichtung automatisiert sind und im Wesentlichen parallel erfolgen, ist dennoch mit jedem Formatwechsel ein zeitaufwendiger Rüstvorgang verbunden, der insbesondere bei kleinen Auflagen von nur wenigen Buchdecken desselben Formats im wirtschaftlichen Missverhältnis zur eigentlichen Produktionszeit steht.In the event of a format change, the case machine is converted to the new dimensions while the case machine is at a standstill. Although in the meantime in the book cover machines of the generic type, the essential changeover processes are automated by motorized adjustment axis systems via a central control device and essentially take place in parallel, each format change is associated with a time-consuming set-up process, which is economically disproportionate to the actual format, especially in the case of small runs of only a few book covers production time stands.

Die DE102010024232A1 schlägt vor, Leitelemente bei andauernder Produktion und in zeitlicher Abstimmung entsprechend einer jeweils zu fertigenden Buchdecke zu positionieren. Dabei wird eine jeweilige Verstellung durchgeführt, sobald die jeweilige Bearbeitung der vorangegangenen Decke bzw. Deckenteile abgeschlossen ist. Durch eine derartige Umstellung der die Deckelpappen und Rückeneinlagen ausrichtenden Führungen der Pappenzuführung sowie der Einschlageinrichtungen der Seiteneinschlagstation wird die Herstellung von Buchdecken unterschiedlicher aufgeschlagener Breiten ohne Unterbrechung ermöglicht. Das Format der Deckelpappen ist dabei weder in ihrer Höhe noch in ihrer Breite bei andauernder Produktion veränderbar. Die unterschiedlichen aufgeschlagenen Breiten werden lediglich durch die Veränderung der Position der Deckelpappen zueinander erreicht.The DE102010024232A1 suggests positioning guide elements during ongoing production and in a timely manner according to a book cover to be produced. A respective adjustment is carried out as soon as the respective processing of the preceding ceiling or ceiling parts has been completed. Such a conversion of the guides of the cardboard feed, which align the cover boards and spine inserts, as well as the folding devices of the side folding station, makes it possible to produce book covers of different opened widths without interruption. The format of the cover board cannot be changed either in terms of height or width during ongoing production. The different open widths are only achieved by changing the position of the cover boards in relation to one another.

This cardboard magazine 10 stores a stack of raw cardboard sheets 900 of the same format. A first separating device 11 separates the cardboard base sheet 900 lying at the bottom from the supply stack. First transport elements 101 push this bottommost unprocessed cardboard sheet 900 under the stack in a first cardboard transport direction A. The cardboard transport device 12, which is connected to the cardboard magazine 10, takes over the separated unprocessed cardboard sheet 900 and transfers it to the joining device 4.

Die Pappentransporteinrichtung 12 weist stromab aufeinander folgend einen ersten Transportabschnitt 13 und einen zweiten Transportabschnitt 14 mit einer zweiten Transportrichtung B der Pappen 900, 901, 902, 903 auf. Diese zweite Transportrichtung B ist zu der Ausschubrichtung A der ersten Vereinzelungseinrichtung 11 kollinear.The board transport device 12 has a first transport section 13 and a second transport section 14 with a second transport direction B of the boards 900, 901, 902, 903 in succession downstream. This second transport direction B is collinear with the ejection direction A of the first separating device 11 .

Entlang der Pappentransporteinrichtung 12 ist der ersten Vereinzelungseinrichtung 11 in der ersten Pappentransportrichtung A nachfolgend eine Pappenschneidvorrichtung 15 mit einer ersten Längsschneideinrichtung 16 angeordnet. Diese erste Längsschneideinrichtung 16 ist im Bereich des zweiten Transportabschnittes 14 angeordnet und umfasst zwei erste Kreisscheren 106. Die oberen Rundmesser 115 bzw. die unteren Rundmesser der beiden ersten Kreisscheren 106 weisen dieselbe Drehachse auf. Die Drehachse der oberen Rundmesser 115 und die Drehachse der unteren Rundmesser verlaufen parallel zu der Pappentransportebene und quer zu der Pappentransportrichtung A, B.A cardboard cutting device 15 with a first longitudinal cutting device 16 is arranged downstream of the first separating device 11 in the first cardboard transport direction A along the cardboard transport device 12 . This first longitudinal cutting device 16 is arranged in the area of the second transport section 14 and comprises two first circular shears 106. The upper circular blade 115 and the lower circular blade of the two first circular shears 106 have the same axis of rotation. The axis of rotation of the upper circular blade 115 and the axis of rotation of the lower circular blade run parallel to the cardboard transport plane and transverse to the cardboard transport direction A, B.

Entlang der gemeinsamen Drehachsen sind die beiden ersten Kreisscheren 106 mit einem Abstand zueinander derart im Pappentransportpfad angeordnet, dass die zugeführten Pappenbogen im Durchlauf jeweils in drei Pappenelemente 901, 902, 903 getrennt werden.The two first rotary shears 106 are arranged at a distance from one another in the cardboard transport path along the common axes of rotation in such a way that the supplied cardboard sheets are each separated into three cardboard elements 901, 902, 903 as they pass through.

Jede der ersten Kreisscheren 106 ist mit jeweils einer Zustelleinrichtung 107 antriebsverbunden. Die Zustelleinrichtungen 107 sind steuerbar über eine erste Datenleitung 801 mit der Steuerungsvorrichtung 8 der Deckenmaschine verbunden. Sie weisen jeweils Zustellelemente bekannter Art auf, wie bspw. Spindeltriebe, mit Zustellrichtungen quer zu der zweiten Pappentransportrichtung B der Pappen 900 im zweiten Transportabschnitt 14.Each of the first rotary shears 106 is drive-connected to an infeed device 107 in each case. The infeed devices 107 are controllably connected to the control device 8 of the ceiling machine via a first data line 801 . They each have infeed elements of a known type, such as spindle drives, with infeed directions transverse to the second board transport direction B of the boards 900 in the second transport section 14.

Der ersten Längsschneideinrichtung 16 nachfolgend angeordnet ist eine in Fig. 2 gezeigte Spreizeinrichtung 18. Diese Spreizeinrichtung 18 positioniert Pappenelemente 901, 902, 903 derselben Decke quer zu der zweiten Transportrichtung B zueinander.Arranged downstream of the first longitudinal cutting device 16 is an in 2 shown spreading device 18. This spreading device 18 positions cardboard elements 901, 902, 903 of the same cover transversely to the second transport direction B to one another.

Dazu erzeugt sie unterschiedliche Transportrichtungen D, E der äußeren Pappenelemente 901, 902, welche mit der zweiten Transportrichtung B in einer gemeinsamen Ebene orientiert sind. Die vierte Transportrichtung D und die fünfte Transportrichtung E sind also zueinander nicht parallel, vielmehr schließen sie einen Spreizungswinkel α ein.For this purpose, it generates different transport directions D, E of the outer cardboard elements 901, 902, which are oriented with the second transport direction B in a common plane. The fourth transport direction D and the fifth transport direction E are therefore not parallel to one another, rather they enclose an angle of separation α.

Dieser Spreizungswinkel α zwischen der vierten Transportrichtung D und der fünften Transportrichtung E ist größer 0°. Er wird durch linke Führungsrollen 112 und durch rechte Führungsrollen 113 erzeugt. Die linken Führungsrollen 112 und die rechten Führungsrollen 113 sind jeweils derart in einer Leiste oberhalb der Pappentransportebene gelagert, dass sie auf die zu transportierenden äußeren Pappenelemente 901, 902 eine Normalkraft aufbringen. Die Drehachsen K der Führungsrollen 112, 113 weisen zu der zweiten Transportrichtung B einen Vorlaufwinkel β auf. Dieser Vorlaufwinkel β ist veränderbar, indem die jeweilige Leiste mit den Führungsrollen 112, 113 um eine zu der Pappenebene senkrecht orientierte Achse um einen Drehwinkel γ, δ geschwenkt wird. Für diese Einstellung des Vorlaufwinkels β sind in den Figuren nicht dargestellte Zustelleinrichtungen bekannter Art vorgesehen.This angle of spread α between the fourth transport direction D and the fifth transport direction E is greater than 0°. It is guided by left guide rollers 112 and generated by right guide rollers 113. The left-hand guide rollers 112 and the right-hand guide rollers 113 are each mounted in a bar above the cardboard transport plane in such a way that they apply a normal force to the outer cardboard elements 901, 902 to be transported. The axes of rotation K of the guide rollers 112, 113 have a lead angle β to the second transport direction B. This advance angle β can be changed in that the respective bar with the guide rollers 112, 113 is pivoted about an axis oriented perpendicularly to the plane of the cardboard by an angle of rotation γ, δ. Feeding devices of a known type, not shown in the figures, are provided for this setting of the lead angle β.

Die durch die Spreizeinrichtung 18 hervorgerufene Verschiebung der Pappenelemente 901, 902 quer zu der zweiten Transportrichtung B wird durch eine zweite Führungsschiene 104 und durch eine dritte Führungsschiene 120 begrenzt. Die Führungsrollen 112, 113 schieben das jeweilige Pappenelement 901, 902 seitlich gegen die zweite Führungsschiene 104 bzw. gegen die dritte Führungsschiene 120, welche die seitliche Position und die Winkellage des jeweiligen Pappenelementes 901, 902 bestimmen. Für die Anpassung an unterschiedliche Formate und unterschiedliche seitlichen Abstände der Pappenelemente 901, 902, 903 einer Decke zueinander, sind die zweite Führungsschiene 104 durch eine sechste steuerbare Zustelleinrichtung 119 und die dritte Führungsschiene 120 durch eine siebte steuerbare Zustelleinrichtung 121 quer zu der zweiten Transportrichtung B positionierbar. Diese sechste steuerbare Zustelleinrichtungen 119 und siebte steuerbare Zustelleinrichtung 121 sind durch Datenleitungen 801 mit der Steuerung 8 der Deckenmaschine verbunden.The displacement of the cardboard elements 901 , 902 transverse to the second transport direction B caused by the spreading device 18 is limited by a second guide rail 104 and by a third guide rail 120 . The guide rollers 112, 113 push the respective cardboard element 901, 902 laterally against the second guide rail 104 or against the third guide rail 120, which determine the lateral position and the angular position of the respective cardboard element 901, 902. To adapt to different formats and different lateral distances between the cardboard elements 901, 902, 903 of a blanket, the second guide rail 104 can be positioned transversely to the second transport direction B by a sixth controllable infeed device 119 and the third guide rail 120 by a seventh controllable infeed device 121 . This sixth controllable infeed device 119 and seventh controllable infeed device 121 are connected by data lines 801 to the controller 8 of the blanket machine.

Eine zweite Längsschneideinrichtung 17 ist entlang des Pappentransportpfades zwischen der ersten Vereinzelungseinrichtung 11 und der ersten Längsschneideinrichtung 16 angeordnet. Sie umfasst als zweites Schneidwerkzeug 108 eine Kreisschere. Das zweite Schneidwerkzeug 108 ist quer zu der zweiten Transportrichtung B positionierbar. Dazu verfügt es über eine dritte steuerbare Zustelleinrichtung 109. Auch diese dritte steuerbare Zustelleinrichtung 109 ist durch eine erste Datenleitung 801 mit der Steuerungseinrichtung 8 der Deckenmaschine verbunden. Eine automatische Verstellung des zweiten Schneidwerkzeuges 108 auf ein gewünschtes Pappenformat auch bei laufender Produktion ist damit ermöglicht.A second longitudinal cutting device 17 is arranged along the cardboard transport path between the first separating device 11 and the first longitudinal cutting device 16 . It comprises circular shears as the second cutting tool 108 . The second cutting tool 108 can be positioned transversely to the second transport direction B. For this purpose, it has a third controllable infeed device 109. This third controllable infeed device 109 is also connected by a first data line 801 to the control device 8 of the blanket machine. An automatic adjustment of the second cutting tool 108 to a desired cardboard format, even during ongoing production, is thus possible.

Der zweiten Längsschneideinrichtung 17 nachfolgend verfügt die Pappenzufuhr 1 über eine erste Abführeinrichtung 19. Die erste Abführeinrichtung 19 schleust den in der zweiten Längsschneideinrichtung 17 von der Pappe abgetrennten Abschnitt 904 aus der ersten Pappentransportbahn 100. Dazu ist eine Schiene als Ableitelement 117 die erste Pappentransportbahn 100 von oben nach unten durchdringend angebracht. Hinsichtlich des einzelnen Schnittes ist das Ableitelement 117 ortsfest aber für eine Formateinstellung quer verschiebbar.Downstream of the second longitudinal cutting device 17, the cardboard feed 1 has a first discharge device 19. The first discharge device 19 discharges the section 904 separated from the cardboard in the second longitudinal cutting device 17 from the first cardboard transport line 100 attached penetrating top to bottom. With regard to the individual cut, the diverting element 117 is stationary but can be moved transversely for a format setting.

Darüber hinaus weist die Pappenzufuhr 1 eine erste Querschneideinrichtung 45 innerhalb der ersten Pappentransportbahn 100 auf. Die Querschneideinrichtung 45 ermöglicht es, die Pappenrohbogen 900 auf eine gewünschte kleinere Bogenhöhe zu schneiden. Die Querschneideinrichtung wird aus einem Paar zusammenwirkender Schneidzylinder mit jeweils an dessen Umfang angebrachten Messer 114 gebildet. Die Schneidzylinder erstrecken sich quer zu der ersten Transportrichtung A über die erste Pappentransportbahn 100. Ihnen ist ein steuerbarer Antrieb zugeordnet. Ein veränderbares, ungleichförmiges Bewegungsprofil der Rotation erlaubt es auf einfache Weise die Pappen auf taktweise aufeinanderfolgend unterschiedliche Höhen zu schneiden. Eine aus Gründen der Übersichtlichkeit nicht dargestellte weitere Abführeinrichtung leitet den Abschnitt aus der ersten Pappentransportbahn 100.In addition, the cardboard supply 1 has a first cross cutting device 45 within the first cardboard transport path 100 . The cross cutting device 45 makes it possible to cut the raw cardboard sheets 900 to a desired smaller sheet height. The transverse cutter is formed from a pair of cooperating cutting cylinders each having knives 114 mounted on the periphery thereof. The cutting cylinders extend transversely to the first transport direction A over the first cardboard transport track 100. A controllable drive is assigned to them. A changeable, non-uniform movement profile of the rotation allows the cardboard to be cut to different heights in cycles in a simple manner. Another removal device, not shown for reasons of clarity, guides the section out of the first cardboard transport line 100.

Die Schneideinrichtungen 16, 17, 45 ermöglichen es der Deckenmaschine, aus einem einheitlichen Format der Pappenrohbogen 900 Decken 908 unterschiedlicher Formate zu erzeugen. Damit entfällt die Bevorratung verschiedener Pappenrohformate. Außerdem ist eine formatbedingte Einstellung des Pappenmagazins 10 nicht erforderlich.The cutting devices 16, 17, 45 enable the cover machine to produce covers 908 of different formats from a uniform format of the raw cardboard sheets 900. This means there is no need to stock different raw cardboard formats. In addition, a format-related setting of the cardboard magazine 10 is not required.

Der Pappenzufuhr 1 bzgl. der Fügevorrichtung gegenüberliegend verfügt die Deckenmaschine über eine Nutzenzufuhr 2. Die Nutzenrohbogen 905 werden als Stapel im Nutzenmagazin 20 bevorratet. Oberhalb des Nutzenmagazins 20 befindet sich eine zweite Vereinzelungseinrichtung 21. Diese trennt den jeweils obersten Bogen von dem restlichen Nutzenstapel und führt ihn einer Transporteinrichtung 22 zu.Opposite the cardboard feed 1 or the joining device, the cover machine has a blank feed 2. The blank blanks 905 are stored as a stack in the blank magazine 20. Above the benefit magazine 20 is a second separating device 21. This separates the respective top sheet of the remaining blank stack and feeds it to a transport device 22.

Entlang deren Transportrichtung C ist der Nutzenvereinzelung 21 nachfolgend eine dritte Längsschneideinrichtung 23 vorgesehen. Wie die zweite Längsschneideinrichtung 17 verfügt sie über eine Kreisschere 202, welche quer zu der Nutzentransportrichtung C positionierbar ist. Dazu ist der Kreisschere 202 eine weitere steuerbare Zustelleinrichtung zugeordnet. Diese dritte Längsschneideinrichtung 23 ermöglicht es der Deckenmaschine, einen zugeführten Nutzenrohbogen 905 auf die erforderliche Nutzenbreite zu schneiden.A third longitudinal cutting device 23 is provided following the panel separation 21 along its transport direction C. Like the second longitudinal cutting device 17, it has circular shears 202, which can be positioned transversely to the panel transport direction C. For this purpose, a further controllable infeed device is assigned to the circular shears 202 . This third longitudinal cutting device 23 enables the cover machine to cut a blank blank sheet 905 that has been fed in to the required blank width.

Eine in Transportrichtung C der dritten Längsschneideinrichtung 23 nachgeordnete zweite Querschneideinrichtung 24 erlaubt das Zuschneiden des Nutzenrohbogens 905 auf die erforderliche Nutzenhöhe. Die zweite Querschneideinrichtung 24 wird aus einem gegen eine ortsfeste Schneidleiste schneidendes Messer 203 gebildet. Gemeinsam mit der dritten Längsschneideinrichtung 23 können so aus einem Nutzenrohformat beliebige kleinere Nutzenformate zugeschnitten werden.A second transverse cutting device 24 downstream of the third longitudinal cutting device 23 in the transport direction C allows the blank blank sheet 905 to be cut to the required blank height. The second transverse cutting device 24 is formed from a knife 203 cutting against a stationary cutting bar. Together with the third longitudinal cutting device 23, any smaller panel formats can be cut from a raw panel panel.

Im Produktfluss nachfolgend ist eine Eckenabstoßeinrichtung 25 angeordnet. Sie umfasst zwei Paar zueinander koaxial und veränderbar beabstandete Schneidzylinder mit jeweils zwei spiralförmig gestalteten Schneiden. Die beiden spiralförmigen Schneiden eines Zylinders sind einander gegenüberliegend angeordnet und weisen zueinander gegenläufige Steigungen auf. Auch die Eckenabstoßeinrichtung 25 weist einen steuerbaren Einzelantrieb auf. Somit können die Ecken der vorlaufenden sowie der nachlaufenden Kanten des Nutzenbogens im Durchlauf durch diagonal verlaufende Schnitte abgestoßen werden.A corner kick-off device 25 is arranged downstream in the product flow. It comprises two pairs of cutting cylinders spaced coaxially and variably with respect to one another, each with two spiral-shaped cutting edges. The two spiral cutting edges of a cylinder are arranged opposite one another and have opposite gradients. The corner kicking device 25 also has a controllable individual drive. In this way, the corners of the leading and trailing edges of the blank sheet can be pushed off in the run by diagonally running cuts.

Die Nutzentransporteinrichtung 22 führt die vereinzelten Nutzen durch die Schneideinrichtungen 23, 24, 25 der Klebstoffauftragvorrichtung 3 zu. Dazu fixiert ein Nutzenzylinder 400 mit Greifern 401 jeweils die vorlaufende Kante des Nutzenzuschnittes und führt diesen auf seiner Mantelfläche an der Klebstoffauftragvorrichtung 3 entlang. Diese ist aus zu einem Balken zusammengesetzten Düsen 300 gebildet. Es kann jedoch auch ein Walzenleimwerk bekannter Art eingesetzt werden.The panel transport device 22 feeds the individual panels through the cutting devices 23, 24, 25 to the adhesive application device 3. For this purpose, a blank cylinder 400 with grippers 401 fixes the leading edge of the blank blank and guides it along the adhesive application device 3 on its lateral surface. This is composed of a beam Nozzles 300 formed. However, a roller gluing unit of a known type can also be used.

Die Pappenzufuhrrichtung a, B, tangiert den Nutzenzylinder 400 derart, dass im Durchlauf der beleimte Nutzenzuschnitt an die Pappenelemente angerollt wird. Eine im Fügebereich angeordnete Gegendruckwelle 403 erzeugt dabei einen zusätzlichen Druck auf die Kleblinge.The cardboard feed direction a, B affects the blank cylinder 400 in such a way that the glued blank blank is rolled onto the cardboard elements as it passes through. A counter-pressure wave 403 arranged in the joining area generates additional pressure on the bonded parts.

Das so erzeugte Werkstück durchläuft die Einschlagvorrichtung 5 der Deckenmaschine. Diese umfasst zwei Einschlageinrichtungen 50, 51 bekannter Art. Auf die Fügevorrichtung 4 folgt die Kopf- und Fußeinschlagvorrichtung. Sich quer zu der Transportrichtung B der Pappenelemente 901, 902, 903 erstreckende Leisten 501 richten die vor- und die nachlaufenden Überstände des beleimten Nutzens durch eine im wesentlichen vertikale Relativbewegung zu den Pappenelementen 901, 902, 903 entlang der durch Pappenkanten gebildeten ersten Biegelinien 500 auf. Einschlagschienen 502 schlagen die aufgerichteten Überstände durch lineare Bewegungen parallel u der Transportrichtung B der Pappenelemente 901, 902, 903 auf die Deckeninnenseite um und reiben sie an den Pappenelementen 901, 902, 903 an.The workpiece produced in this way runs through the wrapping device 5 of the ceiling machine. This includes two impact devices 50, 51 of a known type. The head and foot impact device follows the joining device 4 . Strips 501 extending transversely to the transport direction B of the cardboard elements 901, 902, 903 straighten up the preceding and following projections of the glued copy by a substantially vertical relative movement to the cardboard elements 901, 902, 903 along the first bending lines 500 formed by cardboard edges . Wrap-in rails 502 turn the erected supernatants by linear movements parallel u to the transport direction B of the cardboard elements 901, 902, 903 onto the inside of the ceiling and rub them against the cardboard elements 901, 902, 903.

Allen Einschlagelementen 501, 502, 505, 506 sind steuerbare Zustelleinrichtungen 503, 507 zugeordnet, durch welche sie passend zum zu fertigenden Deckenformat positioniert werden.All wrapping elements 501, 502, 505, 506 are assigned controllable infeed devices 503, 507, through which they are positioned to match the ceiling format to be manufactured.

Anschließend wird der Teilekomplex in die Seiteneinschlageinrichtung verbracht und auf Auflageschienen 505 abgelegt. Zweite Einschlagschienen 506 schwenken aus einer Startposition unterhalb der seitlichen Pappenüberstände auf die Deckel 901, 902. Dabei erfassen sie die seitlichen Nutzenüberstände und schlagen sie entlang seitlicher Biegelinien 504 auf die Pappen 901, 902 ein.The complex of parts is then brought into the side wrapping device and placed on support rails 505. Second wrapping rails 506 pivot from a starting position below the lateral cardboard overhangs onto the covers 901, 902. In doing so, they grasp the lateral blank overhangs and fold them along lateral bending lines 504 onto the cardboard 901, 902.

Die fertig eingeschlagenen Decken 908 durchlaufen eine der Einschlagvorrichtung 5 nachgeordnete Anrolleinrichtung, welche die Kleblinge 901, 902, 903, 909 im Durchlauf miteinander verpresst. Eine nachfolgend angeordnete Ausfuhrvorrichtung 6 transportiert die Decken 908 aus der Deckenmaschine, um sie der weiteren Verarbeitung oder einer Zwischenlagerung verfügbar zu machen.The finished folded blankets 908 pass through a rolling device which is arranged downstream of the wrapping device 5 and which presses the adhesive sheets 901, 902, 903, 909 together as they pass through. A subsequently arranged discharge device 6 transports the covers 908 out of the cover machine in order to make them available for further processing or intermediate storage.

Für eine gute Bedienbarkeit der Magazine 10, 20 sind diese wie die Ausfuhr 6 in etwa derselben ergonomischen Höhe angeordnet. Dazu sind die Transportrichtungen A, B, C, D, E der Pappenzufuhr 1 von dem Pappenmagazin 10 zu der Fügevorrichtung 4 ansteigend orientiert.For good usability of the magazines 10, 20, these are arranged at approximately the same ergonomic height as the outlet 6. For this purpose, the transport directions A, B, C, D, E of the cardboard feed 1 are oriented upwards from the cardboard magazine 10 to the joining device 4 .

Die Deckenmaschine umfasst auch eine Steuerung 8 mit einem Datenspeicher 800, in welchem Produktionsparameter und den Fertigungsaufträgen zugeordnete Formatdaten der gefertigten und der zu fertigenden Decken 908 sowie deren Einzelteile 901, 902, 903, 909 und Ausgangsmaterialien 900, 905 abgelegt sind.The ceiling machine also includes a controller 8 with a data memory 800, in which production parameters and the production orders assigned format data of the finished and to be produced ceilings 908 and their individual parts 901, 902, 903, 909 and starting materials 900, 905 are stored.

Sämtliche steuerbare Zustelleinrichtungen 105, 107, 109, 503, 507 sind durch erste Datenleitungen 801 und sämtliche steuerbare Antriebe 118, 205, 206, 207 durch weitere Datenleitungen 803 mit der Steuerung 8 verbunden. Über diese versorgt die Steuerung 8 anhand der in dem Datenspeicher 800 hinterlegten Daten die Antriebe 118, 205, 206, 207 und Zustelleinrichtungen 105, 107, 109, 503, 507 mit produkt- und produktionsabhängigen Sollwerten. Istwerte werden an die Steuerung 8 geleitet.All controllable delivery devices 105, 107, 109, 503, 507 are connected to controller 8 by first data lines 801 and all controllable drives 118, 205, 206, 207 by further data lines 803. The controller 8 uses this to supply the drives 118, 205, 206, 207 and delivery devices 105, 107, 109, 503, 507 with product- and production-dependent target values using the data stored in the data memory 800. Actual values are sent to the controller 8.

Im Bereich der Nutzenzufuhr 2 ist eine Erfassungseinrichtung 700 vorhanden. Diese erfasst eine auf dem Nutzen 905 vorhandene Kennzeichnung, sobald ein Nutzen 905 deren Erfassungsbereich 701 durchläuft. Als Erfassungseinrichtung 700 wird beispielhaft eine Kamera eingesetzt, welche den jeweils auf den Nutzen gedruckten Datamatrix-Code liest und die erfassten Informationen über eine Datenleitung 802 der Steuerung 8 übermittelt. Aus dem Kennzeichen werden die Sollwertvorgaben der Antriebe 118, 205, 206, 207 und Zustelleinrichtungen 105, 107, 109, 503, 507 ermittelt und an diese übertragen.
