Description

Die Erfindung betrifft ein Fahrgestell für einen Heftlagenstapler, wobei das Fahrgestell an einem Förderweg des Staplers entlang verfahrbar ist und mit einer Stützgabel sowie einer Anschlaggabel ausgerüstet ist.The invention relates to a chassis for a staple stacker, the chassis being movable along a conveyor path of the truck and equipped with a support fork and a stop fork.

Es sind verschiedene Fahrgestellarten für Heftlagenstapler, zum Beispiel für waagerechte Stapler, bekannt, die den Nachteil aufweisen, dass das gebildete Paket stets eine bestimmte, nicht veränderbare Länge haben muss, die zwangsläufig dem festen Abstand zwischen den Gabeln entspricht. Deshalb ist die Anzahl von Heftlagen einer bestimmten Art für das entsprechend gebildete Paket unveränderlich und nicht beeinflussbar.There are various types of chassis for staple stackers, for example for horizontal stackers, which have the disadvantage that the package formed must always have a certain, unchangeable length which inevitably corresponds to the fixed distance between the forks. For this reason, the number of stapling layers of a certain type cannot be changed for the correspondingly formed package and cannot be influenced.

Ein weiterer Nachteil besteht darin, dass bei unterschiedlichen Heftlagenarten die Anzahl der Heftlagen eines jeden gebildeten Pakets aufgrund ihres jeweiligen Raumbedarfes in Längsrichtung des gebildeten Pakets nicht gleichbleibend ist.Another disadvantage is that, with different types of booklet layers, the number of booklet layers of each package formed is not constant in the longitudinal direction of the package formed due to their respective space requirements.

Der Erfindung liegt die Aufgabe zugrunde, ein Fahrgestell für einen Stapler zu schaffen, das die Nachteile des Standes der Technik nicht aufweist und in der Lage ist, unterschiedliche Länge aufweisende Pakete herzustellen.The invention has for its object to provide a chassis for a forklift that does not have the disadvantages of the prior art and is able to produce packages of different lengths.

Diese Aufgabe wird mit einem Fahrgestell für einen Heftlagenstapler gelöst, wobei das Fahrgestell an einem Förderweg des Staplers entlang verfahrbar ist und mit einer Stützgabel sowie einer Anschlaggabel ausgerüstet ist, dadurch gekennzeichnet, dass das Fahrgestell ein Teleskop aufweist, das dazu geeignet ist, die Fahrgestellänge zu verändern.This object is achieved with a chassis for a staple stacker, the chassis being movable along a conveying path of the truck and equipped with a support fork and a stop fork, characterized in that the chassis has a telescope which is suitable for the length of the chassis change.

Das erfindungsgemässe Fahrgestell weist den Vorteil auf, dass sich innerhalb der durch das Teleskop der kleinsten und der grössten Fahrgestelllänge gegebenen Grenzen Pakete unterschiedlicher Längen einfach und nach Bedarf bilden lassen.The chassis according to the invention has the advantage that within the limits given by the telescope of the smallest and the largest chassis length, packages of different lengths can be formed easily and as required.

Bei einer bevorzugten Ausführungsform weist das Fahrgestell zwei Teile auf, die über das aus einem Zylinder und einem Kolben bestehende Teleskop miteinander verbunden sind.In a preferred embodiment, the chassis has two parts which are connected to one another via the telescope consisting of a cylinder and a piston.

Zweckmässig weist das Teleskop des Fahrgestells ein Sperrgetriebe auf, mit dem der Kolben gegenüber dem Zylinder arretierbar ist.The telescope of the chassis expediently has a locking mechanism with which the piston can be locked in relation to the cylinder.

Das Sperrgetriebe ist vorzugsweise automatisch steuerbar.The locking mechanism is preferably automatically controllable.

Das Teleskop wird zweckmässig durch ein Fluidsystem angetrieben.The telescope is expediently driven by a fluid system.

Der Zylinder des Teleskops ist vorzugsweise im Rahmen des Fahrgestells integriert.The cylinder of the telescope is preferably integrated in the frame of the chassis.

Der Zinken der Anschlaggabel ist zweckmässig zurückziehbar.The tine of the stop fork is conveniently retractable.

Der Fahrgestellteil, der die Anschlaggabel aufweist, kann mittels einer Klemmvorrichtung des Staplers festgeklemmt werden.The chassis part, which has the stop fork, can be clamped by means of a clamping device of the truck.

Die Erfindung wird nachstehend an Hand einiger beispielsweise dargestellter Ausführungsformen näher beschrieben.The invention is described in more detail below with the aid of a number of exemplary embodiments shown.

  • Figure 9 shows the complete stacker.

Figur 1 und 2 zeigen einen Teil des insgesamt mit 1 bezeichneten Staplers, mit einem Fahrgestell 2 im Bildungsbereich 15 eines Pakets 3. Das Fahrgestell 2 ist entlang einem Förderweg 4 des Staplers 1 verfahrbar, und zwar auf bereits bekannte und daher hier nicht näher beschriebene Art und Weise.Figures 1 and 2 show a part of the stacker, generally designated 1, with a chassis 2 in the formation area 15 of a package 3. The chassis 2 can be moved along a conveying path 4 of the stacker 1, in a manner already known and therefore not described in more detail here and way.

Erfindungsgemäss besteht das Fahrgestell 2 aus zwei Teilen 6 und 7, die über ein Teleskop 5 miteinander verbunden sind, das die Veränderung der Länge des Fahrgestells 2 in Abhängigkeit von der für das Paket 3 gewünschten Länge gestattet. Das Teleskop 5 weist einen Zylinder 8 auf, der im Rahmen des Fahrgestells 2 integriert ist, und mit einem Kolben 9 vershen ist.According to the invention, the chassis 2 consists of two parts 6 and 7, which are connected to each other via a telescope 5, which allows the length of the chassis 2 to be changed as a function of the length desired for the package 3. The telescope 5 has a cylinder 8 which is integrated in the frame of the chassis 2 and is provided with a piston 9.

Das Fahrgestell 2 ist mit einer Stützgabel 10 und einer Anschlaggabel 11 ausgerüstet. Die Gabeln 10, 11 sind jeweils mit Zinken 12, 13 versehen, die zur Bildung des Pakets 3 erforderlich sind. Die Zinken 13 sind in das Innere der Anschlaggabel 11 zurückziehbar. Ausserdem weist der Stapler 1 zwei Trennschaufeln 14 zum Trennen des Pakets 3 im Bildungsbereich 15 auf.The chassis 2 is equipped with a support fork 10 and a stop fork 11. The forks 10, 11 are each provided with prongs 12, 13, which are required to form the package 3. The tines 13 are retractable into the interior of the stop fork 11. In addition, the stacker 1 has two separating blades 14 for separating the package 3 in the education area 15.

Die Figuren 3, 4 und 5 stellen den Bildungsbereich 15 während des Trennvorganges des Pakets 3 dar.Figures 3, 4 and 5 show the educational area 15 during the separation process of the package 3.

In Figur 3 sieht man das aus fluchtenden Heftlagen bestehende Paket 3, das durch die Zinken 12 gestützt wird.In Figure 3 you can see the package 3 consisting of aligned stapling, which is supported by the tines 12.

Die Schaufel 14 befindet sich zusammen mit den Zinken 13 der Anschlaggabel 11 in Wartestellung neben dem Bildungsbereich 15 des Pakets 3, wobei die Schaufel 14 und die Zinken 13 miteinander fluchten und zurückgezogen sind.The blade 14 together with the tines 13 of the stop fork 11 is in the waiting position next to the formation area 15 of the package 3, the blade 14 and the tines 13 being aligned with one another and being withdrawn.

Figur 4 zeigt den Anfang des Trennvorganges des Pakets 3, wobei nun die zurückgezogenen Zinken 13 und die Schaufel 14 im Bildungsbereich 15 des Pakets 3 positioniert sind.FIG. 4 shows the beginning of the separation process of the package 3, with the retracted tines 13 and the blade 14 now being positioned in the formation area 15 of the package 3.

Aus Figur 5 ist das Paket 3 ersichtlich, das durch die Schaufel 14 und die ausgezogenen und in den Bildungsbereich 5 ragenden Zinken 13 getrennt worden ist. Die Zinken 13 und die Schaufel 14 fluchten noch miteinander und berühren das gebildete Paket 3.From Figure 5, the package 3 can be seen, which by the Bucket 14 and the extended tines 13 projecting into the area of education 5 have been separated. The tines 13 and the blade 14 are still in alignment with one another and touch the package 3 formed.

Figur 6 zeigt, wie das zwischen den Gabeln 10 und 11 mit ausgezogenen Zinken 12 und 13 festgehaltene Paket 3 durch das Fahrgestell 2 am Förderweg 4 des Staplers 1 entlang transportiert wird. Die ausgezogene Schaufel 14 stützt die Heftlagen des neu zu bildenden Pakets, bis das leere Fahrgestell 2 mit den zurückgezogenen Zinken 13 in die in Figur 2 dargestellte Lage zurückgekehrt ist.FIG. 6 shows how the package 3 held between the forks 10 and 11 with the tines 12 and 13 pulled out is transported along by the chassis 2 along the conveyor path 4 of the stacker 1. The extended blade 14 supports the tack positions of the package to be newly formed until the empty chassis 2 with the retracted tines 13 has returned to the position shown in FIG. 2.

Das Fahrgestell 2 ist in den Figuren 1, 2 und 6 in seiner kleinsten Länge dargestellt. Figur 7 zeigt dasselbe Fahrgestell 2 während des dem in Figur 6 dargestellten Vorganges, aber in seiner grössten Länge. Das vollständig ausgezogenene Teleskop 5 verbindet die Teile 6 und 7 des Fahrgestells 2 miteinander.The chassis 2 is shown in its smallest length in Figures 1, 2 and 6. Figure 7 shows the same chassis 2 during the process shown in Figure 6, but in its greatest length. The fully extended telescope 5 connects the parts 6 and 7 of the chassis 2 with each other.

In Figur 8 ist das das gebildetes Paket 3 tragende Fahrgestell 2 im Festbindebereich 16 des Staplers 1 dargestellt. Es ist ersichtlich, dass das Fahrgestell 2 hier von mittlerer Länge ist, d.h., eine zwischen der kleinst- und der grösstmöglichen Länge liegende Abmessung hat.FIG. 8 shows the chassis 2 carrying the package 3 formed in the binding region 16 of the truck 1. It can be seen that the chassis 2 here is of medium length, i.e. has a dimension lying between the smallest and the greatest possible length.

Figur 9 zeigt den vollständigen Stapler 1, wobei sich das seine kleinste Länge aufweisende Fahrgestell 2 in dem Bildungsbereich 15 des nicht dargestellten Pakets befindet.FIG. 9 shows the complete stacker 1, the chassis 2, which has its smallest length, being located in the Education area 15 of the package, not shown.

Ausserdem ist das Fahrgestell 2 im Festbindebereich 16 mit den Presszangen des Staplers 1 in seiner grössten Länge dargestellt. Die beiden Bereiche 15 und 16 des Staplers 1 sind über den Förderweg 4 miteiander verbunden, an dem das Fahrgestell 2 verfahrbar ist.In addition, the chassis 2 is shown in the binding region 16 with the pressing tongs of the stacker 1 in its greatest length. The two areas 15 and 16 of the truck 1 are connected to one another via the conveyor path 4, on which the chassis 2 can be moved.

Das seine kleinste Länge aufweisende, leere Fahrgestell 2 kehrt mit zurückgezogenen Zinken 13 am Förderweg 4 entlang in den Bildungsbereich 15 des Pakets 3 zurück (siehe Figur 1).The empty chassis 2, which has its smallest length, returns with the tines 13 retracted along the conveyor path 4 into the formation area 15 of the package 3 (see FIG. 1).

Im Bereich 15 wird ein von der ausgezogenen Schaufel 14 gestütztes Paket 3 bereits vorgeformt. Wenn die Zinken 12 des Fahrgestells 2, die ausgezogen bleiben, mit dem Paket 3 in Berührung kommen (siehe Figur 2), wird die Schaufel 14 zurückgezogen und neben den Bildungsbereich 15 des Pakets 3 in Wartestellung gebracht (siehe Figur 3).In the area 15, a package 3 supported by the extended blade 14 is already preformed. When the tines 12 of the chassis 2, which remain extended, come into contact with the package 3 (see FIG. 2), the shovel 14 is withdrawn and placed next to the formation area 15 of the package 3 (see FIG. 3).

In dem Augenblick, in dem die zurückgezogenen Zinken 13 der Anschlaggabel 11 mit der Schaufel 14 fluchten, wird der Teil 6 des Fahrgestells 2, d.h. der Teil mit der Anschlaggabel 11, durch den Stapler 1, zum Beispiel über die Stange eines nicht dargestellten Kolbens, solange zurückgehalten, bis das Paket 3 die gewünschte Länge erreicht hat. In diesem Augeblick fängt der Trennvorgang des Pakets 3 an (siehe Figur 3 bis 5), wobei der Teil 6 des Fahrgestells 2 durch den Stapler 1 freigegeben wird, zum Beispiel in Abhängigkeit von einem Signal, das einer bestimmten Anzahl Heftlagen entspricht.At the moment when the retracted tines 13 of the stop fork 11 are aligned with the shovel 14, the part 6 of the chassis 2, ie the part with the stop fork 11, is moved by the stacker 1, for example over the rod of a piston, not shown, held back until package 3 has reached the desired length. At this moment the separation process of the package 3 begins (see FIGS. 3 to 5), the part 6 of the chassis 2 being released by the stacker 1 for Example depending on a signal that corresponds to a certain number of booklets.

Gleichzeitig wirkt ein nicht dargestelltes Sperrgetriebe, um das Teleskop 5 zu arretieren, d.h., den Kolben 9 gegenüber dem Zylinder 8 zu arretieren. Am Förderweg 4 entlang fördert das Fahrgestell 2 das gebildete Paket 3, das zwischen den ausgezogenen Zinken 12 und den 13 festgehalten wird, bis zum Festbindebereich 16 des Staplers 1 (siehe Figuren 6 bis 8). Wenn das gebildete Paket 3 durch die Presszangen des Staplers 1 angehoben wird, nimmt das Fahrgestell 2 wieder seine kleinste Länge ein, und zwar vorzugsweise automatisch über das nicht dargestellte Fluidsystem. Anschliessend kann das Fahrgestell 2 zum Erstellungsbereich 15 des Pakets 3 zurückfahren.At the same time, a locking mechanism (not shown) acts to lock the telescope 5, i.e. to lock the piston 9 in relation to the cylinder 8. Along the conveyor path 4, the chassis 2 conveys the package 3 formed, which is held between the extended tines 12 and 13, up to the binding region 16 of the stacker 1 (see FIGS. 6 to 8). When the package 3 formed is lifted by the pressing tongs of the stacker 1, the chassis 2 resumes its smallest length, preferably automatically via the fluid system, not shown. The chassis 2 can then move back to the creation area 15 of the package 3.

Das Teleskop 5 kann erfindungsgemäss zum Beispiel auch aus einem Zahnstangensystem zur Veränderung der Länge des Fahrgestells 2 bestehen.According to the invention, the telescope 5 can also consist, for example, of a toothed rack system for changing the length of the chassis 2.
