Description

Die Erfindung betrifft eine Taschenfalzeinrichtung für ein Taschenfalzwerk zum Falzen von Bogen, das seitliche Rahmenelemente aufweist, mit einer Falztasche, der wenigstens drei rahmenseitig gelagerte Falzwalzen in Bogeneinlaufrichtung vorgeordnet sind, mit zwei an den seitlichen Rahmenelementen gegenüberliegend festgelegten Tragleisten für die Falztasche und mit Fixierungseinrichtungen zum lösbaren Festlegen der Falztasche an den Tragleisten in der eingestellten Position der Falztasche.The invention relates to a pocket folding device for a Pocket folding unit for folding sheets, the side frame elements has, with a folding pocket, the at least three folding rollers mounted on the frame side in the direction of sheet entry are arranged with two on the side frame elements opposite support strips for the folding pocket and with fixation devices for releasably fixing the Folding pocket on the support strips in the set position the folding pocket.

Die Fixierung der Falztaschen an den Tragleisten erfolgt gewöhnlich durch Klemmexzenter, die mittels eines Hebels von Hand betätigt werden. Wenn aufgrund eines Stoppers ein Papierstau beseitigt werden muß oder wenn bei auftretenden Falzdifferenzen der Falzwalzenabstand überprüft und neu eingestellt werden muß oder wenn eine Reinigung der Falzwalzen erforderlich wird, muß der Falzraum durch Verschieben der Falztasche auf den Tragleisten freigelegt werden. Dazu müssen zunächst die Klemmexzenter auf beiden Seiten der Falztasche geöffnet werden. Danach muß die Falztasche auf den Tragleisten so weit vom Falzraum weg verschoben werden, daß ausreichend Zugang zu diesem möglich ist. Eine obere Falztasche muß dabei gehoben, eine untere Falztasche gehalten werden. In dieser neuen Position muß dann die Falztasche mit Hilfe der Klemmexzenter wieder festgelegt werden. Diese Arbeitsgänge erfordern zeitaufwendige Handarbeit.The folding pockets are fixed to the support strips usually by means of clamping eccentrics, which are operated by means of a lever Be operated by hand. If a paper jam due to a stopper must be eliminated or if fold differences occur the folding roller distance checked and reset or if cleaning of the folding rollers is required the folder must be moved by moving the folder be exposed on the support strips. To do this, first of all the clamping eccentrics open on both sides of the folding pocket become. Then the folding pocket on the support strips must go so far be moved away from the rebate space that sufficient access to this is possible. An upper fold pocket must be lifted a lower fold pocket can be held. In this new position must then the folding pocket with the help of the clamping eccentric be fixed again. These operations require time consuming Manual work.

Wenn eine bestimmte Falzwerksbreite überschritten wird, kann die Bedienungsperson den Klemmexzenter auf der gegenüberliegenden Seite von der Bedienerseite aus, auf der alle relevanten Bedienelemente angeordnet sind, nicht mehr erreichen. Die Bedienungsperson muß deshalb zur anderen Seite des Taschenfalzwerks gehen, was sehr zeitaufwendig ist. Außerdem lassen sich Falztaschen ab einer bestimmten Größe aufgrund ihres beträchtlichen Gewichts und der ungünstigen Kraftangriffsverhältnisse nicht mehr von einer Bedienungsperson allein positionieren und fixieren.If a certain folder width is exceeded, the operator the clamping eccentric on the opposite Side from the operator side on which all relevant Controls are arranged, no longer reach. The Operator must therefore to the other side of the pocket folder go, which is very time consuming. Let also fold pockets from a certain size due to their considerable weight and the unfavorable force attack conditions no longer by one operator alone position and fix.

Die der Erfindung zugrundeliegende Aufgabe besteht deshalb darin, die Taschenfalzeinrichtung der eingangs genannten Art so auszugestalten, daß alle die Falztasche betreffenden Aktivitäten unabhängig von ihrer Breite, ihrer Größe und ihrem Gewicht von einer Seite des Taschenfalzwerks aus durch eine Person ohne wesentlichen Kraftaufwand bedienbar ist.The object underlying the invention is therefore therein, the pocket folding device of the type mentioned To be designed so that all activities related to the folding pocket regardless of their width, size and size Weight from one side of the pocket folder through one Person can be operated without significant effort.

Diese Aufgabe wird bei der Taschenfalzeinrichtung der eingangs genannten Art dadurch gelöst, daß die Falztasche zumindest im Kontaktbereich mit den Tragleisten aus einem magnetisch wechselwirkenden Material besteht, daß die Tragleisten Elektrohaftmagnete aufweisen, daß die Fixierungseinrichtungen eine Spannungsquelle und einen Schalter für das Erregen und Entregen der Elektrohaftmagnete aufweisen, und daß ein zwischen der Falztasche und wenigsten einem seitlichen Rahmenelement wirkender und an ihnen festgelegter Gewichtskompensator für die Falztasche vorgesehen ist.This task is at the beginning of the pocket folding device mentioned type in that the folding pocket at least in Contact area with the support strips from a magnetically interacting Material is that the support strips electro holding magnets have that the fixing devices a Power source and a switch for excitation and de-excitation have the electromagnet, and that a between the Folding pocket and at least one side frame element and weight compensator attached to them for the Folding pocket is provided.

Mit der so gebauten Taschenfalzeinrichtung ist es möglich, daß eine Person allein von der Bedienerseite aus die magnetische Haltekraft zwischen den Tragleisten und der Falztasche durch Betätigung des Schalters ausschaltet, die Falztasche in die gewünschte Position längs der Tragleiste mit äußerst geringem Kraftaufwand aufgrund der Gewichtskompensation verschiebt, durch Betätigung des Schalters die Elektrohaftmagnete wieder erregt, so daß durch die magnetische Wechselwirkung die Falztasche in der eingestellten Position an den Tragleisten fixiert ist, dann die erforderlichen Maßnahmen in dem nun freien Falzraum ausgeführt werden und anschließend durch Ausschalten der magnetischen Haltekraft die Falztasche wieder mit geringem Kraftaufwand aufgrund der Wirkung des Gewichtskompensators in die Falzstellung zurückbewegt und dort erneut durch Einschalten der magnetischen Haltekraft mit Hilfe des Schalters festgelegt wird.With the pocket folding device built in this way, it is possible that one person alone from the operator side the magnetic Holding force between the support strips and the folding pocket Actuation of the switch turns off, the folding pocket in the desired position along the support bar with extremely little Shifted effort due to weight compensation, by pressing the switch, the electro holding magnets again excited so that the folding pocket by the magnetic interaction fixed to the support strips in the set position is then the necessary measures in the now free Folding space are executed and then by switching off the magnetic holding force the folding pocket again with little Effort due to the effect of the weight compensator in the fold position is moved back and there again by switching on the magnetic holding force with the help of the switch becomes.

Die Lastkraft einer Falztasche wird durch ihr Gewicht, ihren Lagewinkel und ihre Reibung auf den Tragleisten bestimmt. Der Gewichtskompensator, der aus Gas- oder Schraubendruckfedern, aus Gas- oder Schraubenzugfedern, aus pneumatischen Arbeitszylindern oder aus entsprechend vorgesehenen Ausgleichsgewichten bestehen kann, ist so ausgelegt, daß er über einen bestimmten Weg im wesentlichen für eine Gleichsgewichtssituation sorgt. Bei einer oberen Falztasche führt die Lastkraft in Richtung der Falzwalzen, bei einer unteren Falztasche von den Falzwalzen weg. Der Gewichtskompensator bzw. die Gewichtskompensatoren sind jeweils am Rahmenelement und an der Falztasche festgelegt und unter Berücksichtigung des Gewichts der Falztasche, ihrer Neigung und ihrer Reibung ausgelegt.The load capacity of a folding pocket is determined by its weight Position angle and their friction on the support strips determined. The Weight compensator made of gas or helical compression springs, from gas or helical tension springs, from pneumatic working cylinders or from correspondingly provided counterweights can exist, is designed so that it has a certain Path essentially for an equilibrium situation worries. With an upper folding pocket, the load force leads to Direction of the folding rollers, with a lower folding pocket from the Folding rollers gone. The weight compensator or the weight compensators are on the frame element and on the folding pocket fixed and taking into account the weight of the folding pocket, their inclination and their friction.

Um die gewünschte Magnethaftung zu ermöglichen, besteht die Falztasche zumindest im Kontaktbereich mit den Tragleisten, gewöhnlich jedoch insgesamt, aus einem ferromagnetischen Material.To enable the desired magnetic adhesion, there is the Folding pocket at least in the contact area with the support strips, usually, however, all of a ferromagnetic Material.

Die Tragleisten können nur Elektrohaftmagnete, bevorzugt wenigstens einen Elektrohaftmagnet und wenigstens einen Permanent-Elektrohaftmagnet aufweisen.The support strips can only use electro holding magnets, preferred at least one electromagnet and at least one permanent electromagnet exhibit.

Elektrohaftmagnete bestehen aus einem Eisenrückschluß mit Innenpol und Außenpol und einer gleichspannungserregten Spule. Der im eingeschalteten Zustand offene magnmetische Kreis ermöglicht ein Festhalten ferromagnetischer Teile. Beim Abschalten der anliegenden Spannung fällt das zu haltende Teil sofort ab.Electric holding magnets consist of an iron yoke with Inner pole and outer pole and a DC-excited coil. The open magnetic circuit when switched on enables ferromagnetic parts to be retained. When switching off the part to be held falls under the applied voltage immediately.

Permanent-Elektrohaftmagnete sind elektrisch abschaltbare Dauermagnetsysteme und unterscheiden sich von den Elektrohaftmagneten dadurch, daß die Haftkraft ohne Zufuhr elektrischer Energie zur Verfügung steht. Damit ist ein Festhalten ferromagnetischer Teile auch bei Stromausfall möglich. Permanent-Elektrohaftmagnete sind bei gleicher Haftkraft wesentlich größer als Elektrohaftmagnete.Permanent electro holding magnets can be switched off electrically Permanent magnet systems and differ from the electromagnets in that the adhesive force without the supply of electrical Energy is available. This is a hold on Ferromagnetic parts also possible in the event of a power failure. Permanent electro holding magnets are essential with the same adhesive force larger than electro holding magnets.

Handelsüblich sind zylinderförmige oder vierkantstabförmige Haftmagnete in verschiedenen Größen für unterschiedlich große Haftkräfte, wobei entsprechende Gewindebohrungen für ihre Befestigung sowie elektrische Anschlüsse vorgesehen sind. Sie können also direkt als Falztaschentragleisten an den rahmenseitigen Elemente festgelegt werden.Cylindrical or square rod-shaped ones are commercially available Holding magnets in different sizes for different sizes Holding forces, with appropriate threaded holes for their Attachment and electrical connections are provided. she can be used directly as folding pocket support strips on the frame side Elements to be set.

Die Haftkraft, die eine solche Tragleiste bei entsprechender Erregung bereitstellen kann, ist die zum Abreißen eines Werkstücks senkrecht zur Haftfläche erforderliche Kraft, die u.a. von der Größe der Auflagefläche, den Werkstoffeigenschaften, der Materialdicke des Auflageteils, der Rauhheit der Auflagefläche, dem Luftspalt zwischen Tragleiste und Falztasche und der prozentualen Belegung der Haftfläche abhängt. Das Gewicht der Falztasche wirkt parallel zur Haftfläche als Verschiebekraft. Die Verschiebekraft beträgt etwa 20 bis 30% der magnetischen Haftkraft. Dadurch, daß ein Gewichtskompensator vorgesehen ist, der das Gewicht der Falztasche bei ihrer Positionsveränderung auf nahezu Null neutralisiert, wird die gesamte Haftkraft der Tragleisten hundertprozentig wirksam, da das Gewicht der Falztasche als Verschiebekraft keine Rolle spielt. Dadurch können Tragleisten zum Einsatz kommen, deren magnetische Haftkraft relativ klein ist, so daß auch die baulichen Abmessungen kleingehalten werden können. Erst durch die Wechselwirkung zwischen der Gewichtsneutralisierung aufgrund des Gewichtskompensators bzw. der Gewichtskompensatoren und der elektromagnetischen Fixierung aufgrund der Einschaltung oder Ausschaltung der Magnetkraft der Tragleisten ist es möglich, daß eine Bedienungsperson von der Bedienerseite aus mit geringem Zeit- und Kraftaufwand auch große schwere Falztaschen, deren Gewicht 50 Kilogramm überschreiten kann, problemlos handhaben kann. The adhesive force that such a support strip with appropriate Excitation that can provide is that of tearing off a workpiece force required perpendicular to the adhesive surface, which among other things on the size of the contact surface, the material properties, the material thickness of the support part, the roughness of the support surface, the air gap between the support bar and folding pocket and depends on the percentage occupancy of the adhesive area. The weight the folding pocket acts as a displacement force parallel to the adhesive surface. The displacement force is about 20 to 30% of the magnetic Adhesive force. In that a weight compensator is provided is the weight of the folding pocket when changing its position neutralized to almost zero, the total adhesive force of the support strips 100 percent effective because the weight of the folding pocket does not matter as a displacement force plays. As a result, support strips can be used, whose magnetic adhesive force is relatively small, so that the structural dimensions can be kept small. Only by the interaction between weight neutralization due to the weight compensator or the weight compensators and the electromagnetic fixation due to the activation or switching off the magnetic force of the support strips it is possible that an operator from the operator side even large, heavy folding pockets with little effort and time, whose weight can exceed 50 kilograms, easily can handle.

Aufgrund der vorstehend beschriebenen Eigenschaften hat sich eine Kombination aus Elektrohaftmagneten und Permanent-Elektrohaftmagneten an den Tragleisten als zweckmäßig erwiesen.Due to the properties described above a combination of electromagnets and permanent electromagnets on the support strips proved to be useful.

Die Tragleisten können um ihre Längsachsen drehbar gehalten sein. Durch diese pendelnde Aufhängung der Tragleisten ist ein Ausgleich der Durchbiegungen von beispielsweise sehr breiten Falztaschen möglich, so daß das Niveau der Falztasche bezüglich der Falzwalzen nicht verändert wird und sich die magnetische Haftfläche immer dem jeweiligen Gegenstück anpassen kann.The support strips can be rotated about their longitudinal axes his. Due to this swinging suspension of the support strips is a Compensation for the deflections of, for example, very wide ones Folding pockets possible, so that the level of the folding pocket with respect the folding roller is not changed and the magnetic Can always adapt the adhesive surface to the respective counterpart.

a circuit diagram for the magnetic circuit of a support bar.

Das in Fig. 1 gezeigte Taschenfalzwerk hat zwei seitliche Rahmenelemente 11, von denen nur eines gezeigt ist. Zwischen den Rahmenelementen 11 sind die Falzwalzen 23 in paarweiser Zuordnung zwei obere Falztaschen 12 in Bogeneinlaufrichtung 24 vorgeordnet, von denen sich die obere in einer vom Falzraum weg nach oben verschobenen Position und die untere in der Falzposition befindet. Die beiden schematisch gezeigten unteren Falztaschen 22 sind durch Bogenablenker geschlossen.The pocket folder shown in Fig. 1 has two lateral Frame elements 11, only one of which is shown. Between the frame elements 11 are the folding rollers 23 in pairs Assignment of two upper folding pockets 12 in the direction of sheet entry 24 upstream, of which the upper is in one of the rebate moved upward position and the lower one in the Folding position is. The two lower ones shown schematically Folding pockets 22 are closed by sheet deflectors.

Jede der beiden oberen Falztaschen 12 hat einen verstellbaren Bogenanschlag 29 und sitzt auf Tragleisten 13, die entsprechend der gewünschten Neigung der Falztaschen 12 gegenüberliegend an den seitlichen Rahmenelementen 11 festgelegt sind. Die Trag-leiste 13 sitzt in Lagern 15 so, daß sie um ihre Achse 14 drehbar ist. Each of the two upper folding pockets 12 has an adjustable one Bow stop 29 and sits on support strips 13, the corresponding the desired inclination of the folding pockets 12 opposite are fixed to the side frame elements 11. The support bar 13 is seated in bearings 15 so that they are around their Axis 14 is rotatable.

Der Falztasche 12 ist auf der Unterseite ein Gewichtskompensator in Form einer Gasdruckfeder 17 zugeordnet, die, wie in Fig. 1 gezeigt ist, mit dem Ende einer Stange 19 über einen Bügel 20 an der Falztasche 12 festgelegt ist, während das freie Ende ihres Zylinders 17 über einen Bolzen 21 zumindest mit einem seitlichen Rahmenelement 11 verbunden ist. Die Gasdruckfeder 17 ist so ausgelegt, daß sich die Falztasche 12 auf den Tragleisten 13 im wesentlichen ohne Kraftaufwand von Hand zwischen den beiden in Fig. 1 gezeigten Stellungen verschieben läßt.The folding pocket 12 is a weight compensator on the underside assigned in the form of a gas pressure spring 17 which, as in Fig. 1 is shown with the end of a rod 19 over a Bracket 20 is fixed to the folding pocket 12 while that free end of their cylinder 17 via a bolt 21 at least is connected to a side frame element 11. The Gas pressure spring 17 is designed so that the folding pocket 12th on the support strips 13 substantially without effort by Move your hand between the two positions shown in Fig. 1 leaves.

Jede der Tragleisten 13 weist beispielsweise, wie in Fig. 2 gezeigt ist, drei Elektrohaftmagnete und einen Permant-Elektrohaftmagneten auf, die über Leitungen 16 und einen Schalter 26 mit einer Spannungsquelle 25 verbunden sind. Der Spannungsquelle 25 ist ein Hauptschalter 30 vorgeordnet. Die Klemmen 31 und 41 des Schalters 26 sind dem Permanent-Elektrohaftmagneten 27, die Klemmen 51 und 52 des Schalters 26 den Elektrohaftmagneten 28 zugeordnet.Each of the support strips 13 has, for example, as in FIG. 2 is shown, three electromagnets and a permanent magnet electromagnet on that via lines 16 and a switch 26 are connected to a voltage source 25. The voltage source 25 is a main switch 30 upstream. The terminals 31 and 41 of the switch 26 are the permanent electromagnet 27, the terminals 51 and 52 of the switch 26 the electromagnet 28 assigned.

In der gezeigten Aus-Stellung des Hauptschalters 30 fließt kein Strom zur Spannungsquelle 25, so daß nur die Haftwirkung des Permanent-Elektrohaftmagneten vorhanden ist.In the shown off position of the main switch 30 flows no current to the voltage source 25, so that only the adhesive effect of the permanent electro holding magnet is present.

In der Ein-Stellung des Hauptschalters 30, in welcher über den Schalter 26 keine Verbindung zwischen seinen Klemmen 31 und 41 jedoch eine Verbindung zwischen seinen Klemmen 51 und 52 besteht, wirkt an den Tragleisten 13 die volle Haftwirkung des Permanent-Elektrohaftmagneten 27 und der Elektrohaftmagneten 28.In the on position of the main switch 30, in which the Switch 26 has no connection between its terminals 31 and 41 however, a connection between its terminals 51 and 52 exists, acts on the support strips 13, the full adhesive effect of Permanent electro holding magnet 27 and the electric holding magnet 28

Wenn in der Ein-Stellung des Hauptschalters 30 durch entsprechende Betätigung des Schalters 26 die Klemmen 31 und 41 verbunden sind und zwischen den Klemmen 51 und 52 keine Verbindung besteht, was in Fig. 2 nicht gezeigt ist, ist die Tragleiste 13 nicht magnetisch, da die Haftwirkung des Permanent-Elektrohaftmagneten 27 aufgehoben ist und Elektrohaftmagneten 28 nicht erregt sind.When in the on position of the main switch 30 by appropriate Actuation of the switch 26, the terminals 31 and 41 are connected and no connection between terminals 51 and 52 what is not shown in Fig. 2 is Support strip 13 is not magnetic, since the adhesive effect of the permanent electromagnet 27 is canceled and electromagnet 28 not are excited.

Auf diese Weise kann mit Hilfe des Hauptschalters 30 und des Schalters 26 die Haftkraft auf Null, lediglich auf den Wert des Permanent-Elektrohaftmagneten 27 und auf die Haftkraft aller Magnete eingestellt werden. In this way, with the help of the main switch 30 and Switch 26 the adhesive force to zero, only to the value of the permanent electromagnet 27 and the adhesive force of all magnets can be set.
