Abstract

The invention relates to an apparatus for cutting lengths of a backlining running off from a stock roll and for assembling it in an exact position together with supplied cover boards in a roll-on device for the mechanical production of book covers, having a pair of cut-length transport rollers for drawing the backlining forwards and positioning it in a cutting device, and having a series of pairs of lead-in rollers for conveying the backlining cut-to-length through a transport channel into the roll-on device. To achieve very high cutting accuracy and for assembling the backlining and cover board in an exact position, provision is made for the pair of cut-length transport rollers (3) and the pairs of lead-in rollers (4-6) to be drivable intermittently by a common regulating servomotor (12) and, after a specific draw-off length of the backlining (1) has been obtained, for the cut-length transport rollers (3a, 3b) to be capable of being brought into an ineffective state, and for the cutting device (9) to be assigned a clamping device holding the backlining (1). Arranged in the apparatus are, furthermore, control means (14, 17) for positioning the cut-to-length backlining (1) in a stand-by position in the transport channel (2) and for releasing the cut-to-length backlining (1) in time synchronism with the intermittently supplied cover boards (1a). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Ablängen von Abschnitten einer von einer Vorratsrolle ablaufenden Rückeneinlage und zum positionsgenauen Zusammenführen mit zugeführten Deckenpappen in einer Anrolleinrichtung für das maschinelle Herstellen von Buchdecken mit einem Schnittlängentransportwalzenpaar zum Vorziehen der Rückeneinlage und Positionieren in einer Schneideinrichtung und mit einer Reihe von Einfuhrwalzenpaaren zum Fördern der abgelängten Rückeneinlage durch einen Transportkanal in die Anrolleinrichtung.The invention relates to a device for cutting sections of a back inlay running from a supply reel and for bringing them together in position with supplied blankets in a rolling device for the mechanical production of book covers with a pair of cut length transport rollers for pulling the back inlay and positioning in a cutting device and with a number of pairs of infeed rollers Conveying the cut back insert through a transport channel into the rolling device.

In der industriellen Herstellung von Buchdecken gelangen Buchdeckenmaschinen zum Einsatz mit diskontinuierlich oder kontinuierlich arbeitenden Vorrichtungen zum Ablängen der Rückeneinlage, auch Schrenz genannt.In the industrial production of book covers, book cover machines are used with discontinuously or continuously working devices for cutting the back insert, also called Schrenz.

Bei im Schrittbetrieb laufenden bekannten Abzugsvorrichtungen findet ein auf die jeweilige Abschnittlänge einstellbares Kulissenantriebssystem zum Steuern der Transportmittel unter Zwischenschaltung eines Freilaufs Verwendung. Hierbei wirkt die Zugkraft für das Ablängen unmittelbar auf die Vorratsrolle, mit der Folge, daß stets ihr Trägheitsmoment zu überwinden ist, um nach erfolgtem Stillstand die Rolle wieder in Drehbewegung zu versetzen. Aufgrund des sich verändernden Durchmessers ergeben sich unterschiedliche Zugkräfte, was zu Schlupf und somit zu Ungenauigkeiten in der Abschnittslänge führt. Zur Überwindung des Trägheitsmomentes bei Vorratsrollen mit großem Durchmesser besteht zudem die Gefahr des Abrisses bei schmalem, dünnem Schrenzmaterial.In the case of known trigger devices running in stepping mode, a link drive system which can be adjusted to the respective section length is used to control the transport means with the interposition of a freewheel. The tensile force for cutting to length acts directly on the supply reel, with the result that its moment of inertia must always be overcome in order to set the reel in rotary motion once it has come to a standstill. Due to the changing diameter, there are different tensile forces, which leads to slippage and thus to inaccuracies in the section length. In order to overcome the moment of inertia with supply rolls with a large diameter, there is also the danger of tearing off with narrow, thin barrier material.

Den mit Kulissenantriebssystem und Frei lauf arbeitenden Abzugsvorrichtungen sind hinsichtlich einer Taktzahlerhöhung aufgrund der ständig wechselnden Bewegungsrichtung Grenzen gesetzt.The trigger devices, which operate with a link drive system and free-running mechanism, are subject to limits with regard to increasing the number of cycles due to the constantly changing direction of movement.

Es sind ferner Abzugsvorrichtungen in Buchdeckenmaschinen mit einer kontinuierlich laufenden Schrenzabrollung mit einem Schrenzmaterial von einer Vorratsrolle vortransportierenden Saugrad bekannt. Zur Durchtrennung des Schrenzmaterials steht eine Querschneideeinrichtung mit einem Paar umlaufend angetriebenen schräggestellten Querschneidemessern zur Verfügung.Extraction devices in book cover machines with a continuously running Schrenzollollung with a Schrenzmaterial from a supply roll pre-transporting suction wheel are also known. A cross-cutting device with a pair of circularly driven, inclined cross-cutting knives is available for cutting through the barrier material.

Die rotierenden Querschneidemesser verlangen eine stets exakte Abstimmung ihres Antriebs in Abhängigkeit von der jeweiligen Abzugsgeschwindigkeit und Abzugslänge, was sich nur mit einem großen baulichen Aufwand realisieren läßt. Grundsätzlich bleibt dabei die Gefahr der Schrenzlängenungenauigkeit und einer nicht rechtwinkligen Durchtrennung des Schrenzmaterials. Nicht zuletzt kann Längenungenauigkeit aufgrund des nicht schlupffreien Transportes des Saugrads auftreten.The rotating cross-cutting knives always require exact adjustment of their drive depending on the respective take-off speed and take-off length, which can only be achieved with a great deal of construction. Basically, there remains the danger of the string length inaccuracy and a non-rectangular cutting of the string material. Last but not least, length inaccuracy can occur due to the non-slip-free transport of the suction wheel.

Die kontinuierlich arbeitenden Abzugseinrichtungen mit umlaufenden Schneideinrichtungen erfordern zudem einen nicht unerheblichen Umrüstaufwand, was nur von geschultem Personal durchzuführen ist.The continuously operating extraction devices with rotating cutting devices also require a considerable amount of retrofitting work, which can only be carried out by trained personnel.

Aus der DE-OS 36 14 167 ist eine Vorrichtung bekannt, in der für das maschinelle Herstellen von Buchdecken die Rückeneinlage von einer Vorratsrolle abgezogen, von einer Quermesserschneideeinrichtung auf Länge geschnitten und einem Nutzenzylinder der Buchdeckenmaschine zugeführt wird. Zum Erreichen hoher Schnittlängengenauigkeit erfolgt der Schneidvorgang zwischen zwei Transportschritten, wozu ein Schnittlängengetriebe zum Antrieb eines vor der Schneideinrichtung installierten Transportwalzensystems vorgesehen ist, dessen Bereich konstanter Drehbewegung durch zueinander verdrehbar angeordnete Kurvenscheiben der Abschnittslänge des Materials entsprechend einstellbar ist.From DE-OS 36 14 167 a device is known in which the back insert is pulled from a supply roll for the mechanical production of book covers, cut to length by a transverse knife cutting device and fed to a blanket cylinder of the book cover machine. To achieve high cutting length accuracy, the cutting process takes place between two transport steps, for which purpose a cutting length gear for driving one in front of the Cutting device installed transport roller system is provided, the range of constant rotary movement can be adjusted according to the section length of the material by cam disks rotatably arranged relative to each other.

Die Zufuhr des abgelängten Schrenzes zum Nutzenzylinder erfolgt bekanntlich in einem Förderkanal mittels eines Transportwalzensystems, bestehend aus abständig zueinander angeordneten Walzenpaaren, die von einem Schrenztransportgetriebe in Umlauf versetzt werden.As is known, the cut-to-length cut is fed to the utility cylinder in a conveying channel by means of a transport roller system consisting of pairs of rolls which are arranged at a distance from one another and which are set in circulation by a cut-off transport gear.

Schnittlängengetriebe und Schrenztransportgetriebe sind durch eine Vielzahl von Antriebselementen untereinander verbunden. Eine solche Zwangskopplung zweier Bewegungsabläufe mit mechanischen Bauelementen kann mit Toleranzfehlern behaftet sein, die aus Fertigungsungenauigkeiten resultieren, was insbesondere die Schnittlängengenauigkeit und die Genauigkeit beim Zusammenführen des Schrenzes mit den Deckenpappen bei hoher Taktfolge beeinträchtigt.Cut length gear and cross-feed gear are connected to each other by a large number of drive elements. Such a forced coupling of two motion sequences with mechanical components can be subject to tolerance errors which result from manufacturing inaccuracies, which in particular impairs the cutting length accuracy and the accuracy when merging the fence with the cardboard sheets with a high cycle rate.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung der gattungsgemäßen Art für Hochleistungs-Deckenmaschinen zu schaffen, mit der sich höchste Schnittlängengenauigkeit und ein positionsgenaues Zusammenführen von Rückeneinlage und Deckenpappe bei hoher Funktionssicherheit erzielen lassen.The object of the invention is to provide a device of the generic type for high-performance ceiling machines, with which the highest cutting length accuracy and a positionally accurate merging of the back insert and the cardboard can be achieved with high functional reliability.

Zur Lösung dieser Aufgabe ist die erfindungsgemäße Vorrichtung dadurch gekennzeichnet, daß das Schnittlängentransportwalzenpaar und die Einfuhrwalzenpaare taktweise von einem gemeinsamen geregelten Servomotor antreibbar und die Schnittlängentransportwalzen nach Erreichen einer definierten Abzugslänge der Rückeneinlage in einen wirkungslosen Zustand bringbar sind, daß der Schneideinrichtung eine die Rückeneinlage haltende Klemmeinrichtung zugeordnet ist und daß Steuermittel zum Positionieren der abgelängten Rückeneinlage in einer Warteposition im Transportkanal und zum Freigeben der abgelängten Rückeneinlage in zeitlicher Abstimmung mit den taktweise zugeführten Deckenpappen vorgesehen sind.To achieve this object, the device according to the invention is characterized in that the pair of cut length transport rollers and the pair of feed rollers are cyclically driven by a common, controlled servo motor and the cut length transport rollers can be brought into an ineffective state after a defined pull-off length of the back insert has been achieved, that the cutting device is assigned a clamping device holding the back insert is and that control means for positioning the cut back insert in a waiting position in the transport channel and for releasing the cut back insert are provided in timing with the cyclically fed cardboard.

Ein Ausführungsbeispiel der Erfindung wird anhand schematischer Darstellungen des konstruktiven Aufbaus der Vorrichtung in verschiedene Ablaufphasen in den Figuren 1 bis 3 erläutert.An exemplary embodiment of the invention is explained on the basis of schematic representations of the constructive structure of the device in different operational phases in FIGS. 1 to 3.

Ein Fördersystem für die Rückeneinlage 1, auch als Schrenz bezeichnet, wird von einem Transportkanal 2 und einer Reihe von abständig zueinander angeordneten Transportwalzenpaaren 3-6 gebildet, mit der Aufgabe, die Rückeneinlage 1 in eine Anrolleinrichtung, bestehend aus einem sogenannten Nutzenzylinder 7 und mit einer Oberwalze 8, zu fördern, in der die Rückeneinlage 1 positionsgenau mit zugeführten Deckenpappen 1a zusammengebracht wird.A conveyor system for the back insert 1, also referred to as Schrenz, is formed by a transport channel 2 and a number of spaced-apart pairs of transport rollers 3-6, with the task of inserting the back insert 1 into a rolling device consisting of a so-called utility cylinder 7 and with a To promote top roller 8, in which the back insert 1 is brought into position with the supplied cardboard sheets 1a.

Dem ersten Transportwalzenpaar 3 nachgeordnet ist eine Schneideinrichtung 9 sowie eine zwischen dieser und dem Walzenpaar 3 installierte, die abzulängende Rückeneinlage 1 haltende Klemmeinrichtung 10. Schneid- und Klemmeinrichtung 9 bzw. 10sind miteinander gekoppelt und werden durch bekannte pneumatische Antriebsmittel 11 betätigt.Downstream of the first pair of transport rollers 3 is a cutting device 9 and a clamping device 10 installed between the latter and the pair of rollers 3 and holding the back insert 1 to be cut. Cutting and clamping devices 9 and 10 are coupled to one another and are actuated by known pneumatic drive means 11.

Erfindungsgemäß wird das der Schneideinrichtung 9 und der Klemmeinrichtung 10 vorgeordnete erste Transportwalzenpaar 3 zum Ablängen der Rückeneinlage 1 von einer nicht dargestellten Vorratsrolle, nachfolgend als Schnittlängentransportwalzen bezeichnet, und die nachgeordneten Transportwalzenpaare 4-6, nachfolgend Zufuhrtransportwalzen genannt, taktweise von einem gemeinsamen geregelten Servomotor 12 über eine Kette 13 angetrieben, wobei jeweils eine Walze direkt mit dem Servomotor 12 über die Kette 13 antriebsmäßig gekoppelt und die gegenüberliegende Walze durch Reibschluß mitgenommen wird.According to the invention, the first pair of transport rollers 3 arranged in front of the cutting device 9 and the clamping device 10 for cutting the back insert 1 to length from a storage roll (not shown), hereinafter referred to as cut length transport rollers, and the downstream transport roller pairs 4-6, hereinafter referred to as feed transport rollers, are clocked by a common, controlled servo motor 12 a chain 13 driven, each roller directly coupled to the servo motor 12 via the chain 13 and the opposite roller is carried by friction.

Während die gegenüberliegenden Walzen der Zufuhrtransportwalzen 4-6 permanent mitangetrieben werden, findet bei dem Schnittlängentransportwalzenpaar 3 eine Unterbrechung der Förderbewegung der Rückeneinlage 1 statt, was durch Abstandsveränderung erfolgt, indem die gegenüberliegende Walze 3b von der direkt angetriebenen weiterlaufenden Walze 3a, betätigt durch die pneumatischen Antriebsmittel 11, getrennt wird. Das Ansteuern der Walze 3b zur Unterbrechung der Rückeneinlagenzufuhr erfolgt nach Erreichen einer definierten Abzugslänge in zeitlicher Abstimmung mit der Zufuhr der Rückeneinlage 1 und den zugeführten Deckenpappen 1a in die Anrolleinrichtung 7, 8.While the opposite rollers of the feed transport rollers 4-6 are permanently driven, in the cut length transport roller pair 3 there is an interruption in the conveying movement of the back insert 1, which is done by changing the distance, in that the opposite roller 3b is actuated by the pneumatic drive means by the directly driven further roller 3a 11, is separated. Driving the roller 3b for interruption the back insert is supplied after reaching a defined withdrawal length in time with the supply of the back insert 1 and the supplied cardboard sheets 1a into the curling device 7, 8.

Ein Synchronlauf der Rückeneinlage 1 zu den Deckenpappen 1a im Hinblick auf ein positionsgenaues Zusammenführen wird über eine Regeleinrichtung durch permanentes Abgleichen erreicht, indem die Bewegung der Deckenpappen 1a als Leitantrieb über eine Meßeinrichtung, bestehend aus einem Mitnehmer 15 und einem Inkrementalgeber 16, erfaßt und das Ergebnis einem elektronischen Antriebsregler 17 zur Steuerung des Servomotors 12 zugeführt wird.A synchronous movement of the back insert 1 to the blankets 1a with a view to a precise merging is achieved via a control device by permanent adjustment, in that the movement of the blankets 1a as a master drive via a measuring device, consisting of a driver 15 and an incremental encoder 16, is detected and the result an electronic drive controller 17 for controlling the servo motor 12 is supplied.

Der Bewegungsablauf der erfindungsgemäßen Vorrichtung zum Ablängen von Abschnitten einer Rückeneinlage und zum positionsgenauen Zusammenführen mit den Deckenpappen ergibt sich wie folgt:The sequence of movements of the device according to the invention for cutting sections of a back insert to length and for bringing them together with the cover cardboard results in the following way:
