Abstract

The method uses a lower transport chain and an upper plate chain (14) between which folded sheets (11) are conveyed with their leading edges (12) protruding in the direction of movement (10). Needles (17) are deployed through holes (16) in the links (15) of the plate chain at a stitching station (6). An optical barrier (1) detects the passage of the leading edge and triggers a control unit (4) in which the distribution of stitches is stored. Another detector (2) produces a pulse for each unit of angular rotation of the chain drive shaft (3). The length of the sheets is calculated from the number of pulses counted.

Description

Die Erfindung betrifft ein Verfahren zum Einrichten und Steuern einer Bogen verarbeitenden Maschine mit einem Ausrichtetisch und gegebenenfalls einem Falzwerk, bei welchem mittels eines ersten Gebers und eines mit einem Antriebselement der Maschine gekoppelten zweiten Gebers die Länge eines Bogens ausgemessen wird, die gemessene Bogenlänge abgespeichert und zur Überwachung und Steuerung als Soll-Bogenlänge herangezogen wird.The invention relates to a method for setting up and controlling a sheet-processing machine with an alignment table and optionally a folder, in which the length of a sheet is measured by means of a first transmitter and a second transmitter coupled to a drive element of the machine, the measured sheet length is stored and stored Monitoring and control is used as the target arc length.

Ein solches Verfahren ist aus der DE 40 13 401 A1 bekannt, die hier voll als Offenbarung einzubeziehen ist. Dabei ist der mit dem Antriebselement der Maschine gekoppelte zweite Geber ein Wegfühler, der je Einheitsdrehwinkel eine bestimmte Impulszahl abgibt, so daß die Impulszahl der Einheits-Wegstrecke der Länge der Bögen entspricht. Wenn nach dem bekannten Verfahren der Bogen an einem Geber vorbeigelaufen ist, ist seine Länge bekannt. Über eine Steuereinheit wird dann die bekannte Bogenlänge als Steuergröße verwertet, beispielsweise zur Überwachung des Einlaufs der Bogen von einem Stapel auf den Ausrichtetisch.Such a method is known from DE 40 13 401 A1, which is to be fully incorporated here as a disclosure. The second encoder, which is coupled to the drive element of the machine, is a displacement sensor which emits a specific number of pulses per unit rotation angle, so that the number of pulses of the unit distance corresponds to the length of the arches. If the sheet has passed a sensor using the known method, its length is known. The known sheet length is then used as a control variable via a control unit, for example for monitoring the entry of the sheets from a stack onto the alignment table.

Die der Erfindung zugrunde liegende Aufgabe besteht nun darin, das Verfahren der eingangs genannten Art so auszugestalten, daß sich die Bedienungsvereinfachung aufgrund der Automatisierung auch auf dem Gebiet der Fadensiegelmaschinen verwerten läßt.The object on which the invention is based is to design the method of the type mentioned at the outset in such a way that the simplification of operation can also be exploited in the field of thread sealing machines due to the automation.

Diese Aufgabe wird ausgehend von dem Verfahren der eingangs genannten Art dadurch gelöst, daß auf einer Fadensiegelmaschine abhängig von der gemessenen Länge eines Falzbogens und der feststehenden Fadenstichteilung die Anzahl der maximal möglichen Fadenklammern ermittelt und eingestellt wird.This object is achieved on the basis of the method of the type mentioned at the outset in that the number of the maximum possible thread staples is determined and set on a thread sealing machine depending on the measured length of a folding sheet and the fixed thread stitch division.

Mit dem erfindungsgemäßen Verfahren läßt sich die Bedienung von Fadensiegelmaschinen vereinfachen, da die Anzahl der maximal möglichen Fadenklammern automatisch ermittelt und eingestellt wird.With the method according to the invention, the operation of thread sealing machines can be simplified since the number of the maximum possible thread clips is automatically determined and set.

Wenn längs des Transportwegs des Falzbogens in der Fadensiegelmaschine und gegebenenfalls längs dieses Weges verstellbare weitere Geber vorgesehen werden, ist es möglich, unter Vergleich mit dem ermittelten Längenmaß des Falzbogens den Abstand zwischen den Gebern zu messen, abzuspeichern und zur Überwachung und Steuerung der Maschine heranzuziehen, so daß sich der Durchlauf des Falzbogens durch die Fadensiegelmaschine nach dem Verfolgungsprinzip überwachen läßt. Es läßt sich feststellen, wieviele Falzbogen sich zwischen zwei bestimmten Punkten befinden, was wiederum zu verschiedenen Überwachungszwecken ausgenutzt werden kann. Bleibt beispielsweise ein Falzbogen hängen und dadurch länger unter dem ersten Geber, als es seiner Länge entspricht, wird dadurch ein längerer Falzbogen simuliert, was eine Fehlermeldung ergibt und zum Abschalten der Fadensiegelmaschine führt.If additional sensors are provided along the transport path of the folded sheet in the thread sealing machine and possibly along this path, it is possible to measure, save and use the distance between the transmitters in comparison with the determined length of the folded sheet and use them for monitoring and controlling the machine. so that the passage of the folded sheet through the thread sealing machine can be monitored according to the principle of tracking. It can be determined how many folded sheets are between two specific points, which in turn can be used for various monitoring purposes. If, for example, a folded sheet gets stuck and is therefore longer under the first encoder than its length, a longer folded sheet is simulated, which results in an error message and leads to the thread sealing machine being switched off.

Anhand einer Zeichnung, die einen Ausschnitt einer Fadensiegelmaschine zeigt, wird die Erfindung näher erläutert.The invention is explained in more detail with the aid of a drawing which shows a section of a thread sealing machine.

Die in der Zeichnung gezeigte Fadensiegelmaschine hat eine nicht gezeigte untere Transportkette und eine obere Plattenkette 14, zwischen denen Falzbogen 11 durch die Fadensiegelmaschine transportiert werden, und zwar mit der Vorderkante 12 voraus in der Transportrichtung, die durch den Pfeil 10 gekennzeichnet ist. Die Plattenkette 14 hat Plattenelemente 15 mit Öffnungen 16, durch die an einer Einstichstelle 6 Nadeln 17 hindurch und durch den Falzbogen 11 hindurch stechen und dabei einen nicht gezeigten, vorher abgelängten Faden zur Bildung einer nachfolgend zu siegelnden Fadenklammer anzubringen.The thread sealing machine shown in the drawing has a lower transport chain, not shown, and an upper plate chain 14, between which folded sheets 11 are transported by the thread sealing machine, with the leading edge 12 ahead in the transport direction, which is indicated by the arrow 10. The plate chain 14 has plate elements 15 with openings 16 through which needles 17 pierce at a puncture point 6 and through the folded sheet 11 and thereby attach a thread, not shown, which has been cut to length in order to form a thread clip to be subsequently sealed.

In der Fadensiegelmaschine ist ein erster Geber 1, beispielsweise eine Lichtschranke, angeordnet, die den Durchgang der Falzbogenvorderkante 12 feststellt. Der erste Geber 1 ist über eine Steuerleitung 22 mit einer Steuereinheit 4 verbunden.A first sensor 1, for example a light barrier, is arranged in the thread sealing machine and determines the passage of the leading edge 12 of the folded sheet. The first transmitter 1 is connected to a control unit 4 via a control line 22.

Die Plattenkette 14 wird durch ein Kettenrad 13 angetrieben, das auf der Welle eines Antriebselements 3 sitzt. Dem Antriebselement 3 ist ein zweiter Geber 2 zugeordnet, der über eine Steuerleitung 23 mit der Steuereinheit 4 verbunden ist. Die Umfangsgeschwindigkeit des Antriebselements 3 ist proportional zur Bewegungsgeschwindigkeit der Plattenkette 14 und damit des Falzbogens 11. Wenn der Geber 2 von einem Wegfühler gebildet wird, gibt dieser je Einheits-Drehwinkel eine bestimmte Impulszahl ab, so daß die Impulszahl der Einheits-Wegstrecke des Falzbogens entspricht.The plate chain 14 is driven by a chain wheel 13, which sits on the shaft of a drive element 3. A second transmitter 2 is assigned to the drive element 3 and is connected to the control unit 4 via a control line 23. The peripheral speed of the drive element 3 is proportional to the speed of movement of the plate chain 14 and thus of the folding sheet 11. If the encoder 2 is formed by a displacement sensor, this emits a certain number of pulses per unit angle of rotation, so that the number of pulses corresponds to the unit distance of the folding sheet .

Der erste Geber 1 stellt die Ankunft der Vorderkante 12 eines Falzbogens 11 fest, meldet dies über die Steuerleitung 22 an die Steuereinheit 4 und aktiviert gleichzeitig über die Steuereinheit 4 den zweiten Geber 2, der so lange Impulszahlen der Einheits-Wegstrecken an die Einheit 4 meldet, bis die nicht gezeigte Hinterkante des Falzbogens 11 am ersten Geber 1 vorbeigelaufen ist. Aus den gezählten Impulsen ermittelt dann die Steuereinheit 4 die Länge des Falzbogens 11.The first transmitter 1 detects the arrival of the leading edge 12 of a folded sheet 11, reports this to the control unit 4 via the control line 22 and simultaneously activates the second transmitter 2 via the control unit 4, which reports the number of pulses of the unit distances to the unit 4 until the rear edge, not shown, of the folded sheet 11 has passed the first transmitter 1. The control unit 4 then determines the length of the folded sheet 11 from the counted pulses.

In der Steuereinheit 4 ist die feststehende Fadenstichteilung der Plattenkette 11 gespeichert.The fixed thread stitch division of the plate chain 11 is stored in the control unit 4.

Die mit einer speziell entwickelten Software arbeitende, von einem Mikroprozessor gebildete Steuereinheit 4 ermittelt dann abhängig von der in der beschriebenen Weise gemessenen Länge des Falzbogens 11 und der durch die Fadensiegelmaschine vorgegebenen Fadenstichteilung die Anzahl der maximal möglichen Fadenklammern, die längs des durch die Fadensiegelmaschine durchlaufenden Falzbogens angebracht werden kann, ohne daß Fäden der Fadenklammern an der Falzbogenvorderkante oder Falzbogenhinterkante nach der Siegelung überstehen.The control unit 4, which uses a specially developed software and is formed by a microprocessor, then determines, depending on the length of the folding sheet 11 measured in the manner described and the thread stitch division specified by the thread sealing machine, the number of maximum possible thread clips which are along the folding sheet passing through the thread sealing machine can be attached without the threads of the thread clips protruding from the leading edge or trailing edge of the folded sheet after sealing.
