Description

Die Erfindung betrifft eine Einrichtung zum Steuern einer kontinuierlich arbeitenden Stapelhebevorrichtung einer bogenverarbeitenden Maschine, bei welcher die Stapelhebevorrichtung einen regelbaren Antrieb aufweist, der durch eine die Höhenlage der Oberseite des Bogenstapels erfassenden Einrichtung beeinflussbar ist, wobei der Antrieb der Stapelhebevorrichtung mittels eines eine elektrische Getriebefaktorverstellung aufweisenden Servomotors erfolgt.The invention relates to a device for controlling a continuously operating stack lifting device a sheet-processing machine, in which the stack lifting device an adjustable Has drive, which by the height of the top of the sheet stack Device can be influenced, the drive of the stack lifting device using an electrical one Servo motor having gear ratio adjustment.

Derartige Stapelhebevorrichtungen bestehen aus einem einen Bogenstapel tragenden Stapelhubtisch, der durch eine Elektromotor heb- und senkbar antreibbar ist. Vom Bogenstapel wird der jeweils oberste Bogen im Takt einer nachgeordneten bogenverarbeitenden Maschine vereinzelt und dieser zugeführt. Das Höhenniveau der Oberseite des Stapels wird von einer Einrichtung erfasst und sowohl beim Erreichen eines oberen als auch unteren Niveaus ein entsprechendes Signal einer Steuereinheit zugeführt, durch die ein Zu- oder Abschalten des Elektromotors erfolgt.Such stack lifting devices consist of a stack lifting table carrying a sheet stack, which can be driven and raised by an electric motor. Each of the sheet stacks the uppermost sheet in time with a subordinate sheet processing machine and this fed. The height level of the top of the stack is detected by one device and both a corresponding signal from a control unit when an upper and lower level is reached supplied, by which the electric motor is switched on or off.

Aus der DE 44 10 384 C1 ist es bekannt, nach Einschalten der Stapelvorrichtung den Stapelhubtisch bis zum Auslösen eines oberen Niveausignals anzuheben und in dieser Position zu halten. Nach dem Auslösen des oberen Niveausignals werden von einem Zähler die Anzahl der vom Bogenstapel entnommenen Bogen bis zum Auslösen des unteren Niveausignals erfasst und ein entsprechendes Signal der Steuereinheit zugeleitet Nach dem Auslösen des unteren Niveausignals wird durch den eine elektrische Getriebefaktorverstellung aufweisenden Elektromotor der Stapelhubtisch wieder angehoben bis zum zweiten Auslösen des oberen Niveausignals. Von der Steuereinheit wird dann aus der Höhendifferenz zwischen dem oberen und unteren Niveau und der Anzahl der gezählten Bogen die Bogenstärke sowie aus der Bogenstärke und der Taktzeit eine Hubgeschwindigkeit ermittelt, die als Ansteuergröße für den Elektromotor nach dem zweiten Auslösen des oberen Niveausignals zum zumindest annähernd kontinuierlichen Antrieb dient. Diese Steuerung ist aufwendig sowie kompliziert und hat den Nachteil, dass zur Ermittlung einer den Stapelhubtisch kontinuierlich nachführenden Geschwindigkeit u. a. die Bogenstärke herangezogen wird, wodurch aufgrund der Tatsache, dass Bogen gleicher Stärke unterschiedliche Eigenschaften aufweisen, die ein messtechnisches Erfassen verfälschen, es zu Fehlmessungen und damit zur Realisierung einer fehlerhaften Hubgeschwindigkeit kommen kann. Außerdem ist es nachteilig, dass durch diese Steuerung jeweils nur eine Hubgeschwindigkeit für eine konkrete Verarbeitungsgeschwindigkeit ermittelt werden kann, so dass bei jeder Abweichung von dieser Verarbeitungsgeschwindigkeit eine neue, eine kontinuierliche Nachführung des Stapelhubtisch sichernde Geschwindigkeit ermittelt werden muss. Damit ist letztlich eine kontinuierliche Nachführung des Stapelhubtischs und damit kontinuierliche Arbeitsweise des Elektomotors nur in Ausnahmefällen möglich.From DE 44 10 384 C1 it is known to switch the stack lifting table after switching on the stacking device until an upper level signal is triggered and hold in this position. To The triggering of the upper level signal shows the number of sheets from the stack removed sheet until the lower level signal is triggered and a corresponding one Signal sent to the control unit After the lower level signal has been triggered, the an electric gear factor adjustment electric motor of the stack lifting table raised again until the upper level signal is triggered a second time. Then from the control unit the difference in height between the upper and lower levels and the number of sheets counted the bow thickness and a stroke speed determined from the bow thickness and the cycle time as a control variable for the electric motor after the second triggering of the upper level signal serves at least approximately continuous drive. This control is complex and complicated and has the disadvantage that in order to determine a continuously tracking the stacking lifting table Speed u. a. the sheet thickness is used, which due to the fact that arches of the same thickness have different properties that a metrological Falsify detection, it leads to incorrect measurements and thus to the realization of an incorrect lifting speed can come. It is also disadvantageous that only one at a time by this control Lifting speed can be determined for a specific processing speed, so that with every deviation from this processing speed, a new one, a continuous one Tracking of the stack lifting table securing speed must be determined. So that is ultimately a continuous tracking of the stacking lifting table and thus continuous operation of the electric motor only possible in exceptional cases.

Aufgabe der Erfindung ist es, eine gattungsgemäße Stapelhebevorrichtung zu schaffen, mit der auf einfache Weise eine kontinuierliche, den jeweiligen Bedingungen angepaßte Hubgeschwindigkeit des Stapelhubtischs realisiert werden kann.The object of the invention is to provide a generic stack lifting device with a simple, continuous lifting speed that is adapted to the respective conditions of the stacking lift table can be realized.

Erfindungsgemäß wird die Aufgabe durch die Patentansprüche gelöst.According to the invention the object is solved by the claims.

Durch die erfindungsgemäße Lösung ist es möglich, eine mit einfachen Mitteln umsetzbare kontinuierlich arbeitende Stapelhebevorrichtung zu schaffen, die es ermöglicht, eine von den jeweiligen Höhenniveaus der Oberseite des Bogenstapels abhängige Stapelhubgeschwindigkeit zu realisieren.The solution according to the invention makes it possible to implement a solution that can be implemented using simple means to provide a continuously operating stacking device that enables one of the stacking speed depending on the respective height levels of the top of the sheet stack to realize.

Die Erfindung wird nachstehend an einem Ausführungsbeispiel näher erläutert. In der zugehörigen Zeichnung ist eine als Bogenanleger 1 ausgebildete Vorrichtung zum Vereinzeln und Fördern von Bogen 6 dargestellt. Dem Bogenanleger 1 ist ein Transportbänder 2 aufweisender Bändertisch 3 nachgeordnet. Die Transportbänder 2 werden durch eine Bänderwalze 4 angetrieben, mit der eine Taktwalze 5 korrespondiert, die im Maschinentakt gegen die Bänderwalze 4 gesteuert wird.
Im Bogenanleger 1 ist ein Stapelhubtisch 8 angeordnet, der durch Hubketten 9 geführt wird. Die Hubketten 9 sind über nicht dargestellte Kettenräder mit einem Elektromotor 10 verbunden. Der Stapelhubtisch 8 wird durch den Elektromotor 10 angehoben oder abgesenkt. Auf dem Stapelhubtisch 8 ist ein aus den Bogen 6 bestehender Bogenstapel 7 angeordnet. Über dem Bogenstapel 7 ist ein gestellfest mit dem Bogenanleger 1 verbundener Saugkopf 11 zum Vereinzeln und Fördern der Bogen 6 vorgesehen. Dazu weist der Saugkopf 11 Trennsauger 12 auf, die den jeweils obersten Bogen 6 des Bogenstapels 7 erfassen, vom Bogenstapel 7 trennen und an ebenfalls im Saugkopf 11 vorgesehene Transportsauger 13 übergeben, die die Bogen 6 in Förderrichtung 14 transportieren, bis der in Förderrichtung 14 vorn liegende Teil der Bogen 6 jeweils von der Wirkpaarung Taktwalze 5/Bänderwalze 4 erfaßt und durch diese bzw. den nachgeordneten Bändertisch 3 zu einer bogenverarbeitenden Maschine transportiert wird. Weiterhin ist im Bogenanleger 1 eine die Höhenlage der Oberseite des Bogenstapels 7 erfassende Einrichtung 15 vorgesehen, die im Ausführungsbeispiel als an sich bekannter Tasterfuß 16 ausgebildet ist, der taktweise gegen die Oberseite des Bogenstapels 7 geführt wird. Die Einrichtung 15 erfaßt die Höhenlage der Oberseite des Bogenstapels 7 in einem Bereich zwischen einer Ober- und einer Untergrenze, wobei zusätzlich eine zwischen diesen Positionen vorgesehene Nullposition erfaßt wird.
Die von der Einrichtung 15 erfaßten Steuersignale werden einer Auswert/Steuereinheit 17 zugeführt. Die von der Auswert/Steuereinheit 17 erzeugten Steuersignale, die dem Regler 18 eines als Servomotor 19 ausgebildeten Elektromotors 10 zugeführt werden, beeinflussen den Getriebefaktor des Servomotors 19 derart, daß dieser schrittweise vergrößert oder verkleinert wird. Dabei wird bei einem großen Getriebefaktor eine höhere Geschwindigkeit des Servomotors 19 und damit eine höhere Stapelhubgeschwindigkeit realisiert, während bei einer Verringerung des Getriebefaktors die Stapelhubgeschwindigkeit reduziert wird, wobei es möglich ist, die Änderung des Getriebefaktors in unterschiedlichen Schrittweiten vorzunehmen.
Das Vereinzeln des jeweils obersten Bogen 6 vom Bogenstapel 7 durch die Trennsauger 12 erfolgt üblicherweise in einer Position, in der sich die Oberseite des Bogenstapels 7 in einer Nullposition befindet, wobei der Bogenstapel 7 kontinuierlich in dem Maß nachgeführt wird, wie die Bogen 6 abgefördert werden. Ist die Stapelhubgeschwindigkeit zu groß, wird also die Oberseite des Bogenstapels 7 durch die Einrichtung 15 in dem Bereich zwischen der Nullposition und einer Obergrenze erfaßt, erfolgt über die Auswert/Steuereinheit 17 und den Regler 18 eine Reduzierung des Getriebefaktors des Servomotors 19 in kleinen Schritten, bis durch die Einrichtung 15 die Oberseite des Bogenstapels 7 als in der Nullposition befindlich dedektiert wird. Wird aber durch die Einrichtung 15 die Oberseite des Bogenstapels 7 an der Obergrenze erfaßt, erfolgt über die Auswert/Steuereinheit 17 und den Regler 18 eine Reduzierung des Getriebefaktors des Servomotors in großen Schritten solange, bis durch die Einrichtung 15 die Oberseite des Bogenstapels 7 in der Nullposition erfaßt wird. Sinkt die Oberseite des Bogenstapels 7 unter die Nullposition ab, so daß sie durch die Einrichtung 15 als im Bereich zwischen der Nullposition und der Untergrenze befindlich erfaßt wird, erfolgt über die Auswert/Steuereinheit 17 und den Regler 18 eine Erhöhung des Getriebefaktors des Servomotors 19 und damit die Nachführgeschwindigkeit des Bogenstapels 7 in kleinen Schritten, bis die Oberfläche des Bogenstapels 7 durch die Einrichtung 15 in der Nullposition erfaßt wird. Erreicht die Oberfläche des Bogenstapels 7 die Untergrenze, wird über die Einrichtung 15, die Auswert/Steuereinheit 17 und den Regler 18 der Getriebefaktor des Servomotors 19 in großen Schritten erhöht und damit ebenso die Nachführgeschwindigkeit des Stapelhubtischs 8 mit dem darauf befindlichen Bogenstapel 7 vergrößert. The invention is explained in more detail below using an exemplary embodiment. In the accompanying drawing, a device designed as a sheet feeder 1 for separating and conveying sheets 6 is shown. The sheet feeder 1 is followed by a belt table 3 having conveyor belts 2. The conveyor belts 2 are driven by a belt roller 4, with which a clock roller 5 corresponds, which is controlled against the belt roller 4 in the machine cycle.
A stack lifting table 8 is arranged in the sheet feeder 1 and is guided by lifting chains 9. The lifting chains 9 are connected to an electric motor 10 via chain wheels (not shown). The stacking lifting table 8 is raised or lowered by the electric motor 10. A sheet stack 7 consisting of the sheets 6 is arranged on the stack lifting table 8. Above the sheet stack 7 there is a suction head 11 connected to the sheet feeder 1 for separating and conveying the sheets 6. For this purpose, the suction head 11 has separating suction devices 12 which capture the uppermost sheet 6 of the sheet stack 7, separate them from the sheet stack 7 and transfer them to transport suction devices 13 which are also provided in the suction head 11 and which transport the sheets 6 in the conveying direction 14 until the front in the conveying direction 14 lying part of the sheet 6 each of the active pairing of the clock roller 5 / belt roller 4 and is transported through this or the downstream belt table 3 to a sheet-processing machine. Furthermore, a device 15 is provided in the sheet feeder 1 which detects the height of the upper side of the sheet stack 7 and which, in the exemplary embodiment, is designed as a feeler foot 16 which is known per se and which is guided in cycles against the upper side of the sheet stack 7. The device 15 detects the height of the top of the sheet stack 7 in a range between an upper and a lower limit, with a zero position provided between these positions also being detected.
The control signals detected by the device 15 are fed to an evaluation / control unit 17. The control signals generated by the evaluation / control unit 17, which are fed to the controller 18 of an electric motor 10 designed as a servo motor 19, influence the gear factor of the servo motor 19 in such a way that it is gradually increased or decreased. In the case of a large gear factor, a higher speed of the servo motor 19 and thus a higher stacking stroke speed is realized, while the stacking speed is reduced when the gear factor is reduced, it being possible to change the gear factor in different increments.
The separation of the uppermost sheet 6 from the sheet stack 7 by the separating suction device 12 is usually carried out in a position in which the upper side of the sheet stack 7 is in a zero position, the sheet stack 7 being continuously tracked to the extent that the sheets 6 are conveyed away , If the stacking stroke speed is too high, ie the top of the sheet stack 7 is detected by the device 15 in the area between the zero position and an upper limit, the transmission / control unit 17 and the controller 18 reduce the gear ratio of the servo motor 19 in small steps, until the device 15 detects the top of the sheet stack 7 as being in the zero position. However, if the upper side of the sheet stack 7 is detected by the device 15 at the upper limit, the evaluation / control unit 17 and the controller 18 reduce the gear ratio of the servo motor in large steps until the upper side of the sheet stack 7 in the device 15 Zero position is detected. If the top of the sheet stack 7 drops below the zero position, so that it is detected by the device 15 as being in the area between the zero position and the lower limit, an increase in the gear ratio of the servo motor 19 and takes place via the evaluation / control unit 17 and the controller 18 thus the tracking speed of the sheet stack 7 in small steps until the surface of the sheet stack 7 is detected by the device 15 in the zero position. If the surface of the sheet stack 7 reaches the lower limit, the gear factor of the servo motor 19 is increased in large steps via the device 15, the evaluation / control unit 17 and the controller 18, and the tracking speed of the stacking lifting table 8 with the sheet stack 7 located thereon is also increased.
