Abstract

The gauge (8) is integrated in the carrier frame (28) of the press tongs (5) for the parcels (51), above the arms (25,26) of the tongs. The gauge consists of two conveyor belts (15,16) for the covers (13). These are in active contact with a device to advance the cover parcels (11,12) to the side walls (9,10). Slide and holder guides (47) for the covers are located between the side walls and the tong arms. Traction elements (29,30) outside the side walls move the covers along the guides onto the arms of the tongs.

Description

Die Erfindung betrifft einen waagerechten Heftlagenstapler mit Klappenanleger.The invention relates to a horizontal stapler with flap feeder.

Bei den bekannten Heftlagenstaplern ist der Klappenanleger im engen Raum oberhalb des Paketbildungsbereiches, zwischen der senkrechten Zuührungsstrecke der Heftlagen und der Presszange des fertigen Pakets angeordnet.In the known staple stacker, the flap feeder is arranged in the narrow space above the package formation area, between the vertical feed path of the staple layers and the pressing tongs of the finished package.

Dadurch wird die Leistung der bekannten Klappenanleger beschänkt und die Bedienungsperson ist gezwungen, die Klappenanleger häufig, d.h. ungefähr alle Viertelstunden, mit neuen Klappen zu beschicken.This limits the performance of the known flap feeders and forces the operator to use the flap feeders frequently, i.e. to load new flaps approximately every quarter of an hour.

Diese häufigen Eingriffe der Bedienungsperson sind nachteilig, weil dadurch die Bedienungsperson viel Zeit verliert, die für andere, eventuell erforderliche Eingriffe benutzt werden könnte. Ein weiterer Nachteil besteht darin, dass einer Bedienungsperson immer nur ein Stapler zugeteilt werden kann und nicht zwei, wie es erwünscht wäre.These frequent operator interventions are disadvantageous because they lose the operator a lot of time that could be used for other interventions that may be required. Another disadvantage is that one Only one stacker can be assigned to the operator, not two, as would be desired.

Das Erfordernis, die Häufigkeit zu beschränken, mit der die Bedienungspersonen zum Beschicken der Klappenanleger eingreifen müssen, ist daher allgemein bekannt und als Nachteil empfunden.The need to limit the frequency with which operators must intervene to load the flap feeders is therefore well known and perceived as a disadvantage.

Der Erfindung liegt die Aufgabe zugrunde, einen waagerechten Stapler mit einem sehr leistungsfähigen Klappenanleger zu schaffen, der in der Lage ist, die Zeit, die die Bedienungsperson für die aufeinanderfolgenden Vorgänge zum Beschicken des Klappenanlegers braucht, entschieden kürzer zu gestalten.The invention has for its object to provide a horizontal stacker with a very powerful flap feeder, which is able to make the time that the operator needs for the successive processes for loading the flap feeder decidedly shorter.

Bei einem gewöhnlichen waagerechten Stapler wird diese Aufgabe erfindungsgemäss durch die Merkmale des Patentanspruches 1 gelöst. Der wesentliche, mit der Erfindung erzielbare Vorteil besteht darin, dass die beträchtliche Länge der Paket-Presszange ausgenutzt wird, um die Leistung des Klappenanlegers zu erhöhen.In a conventional horizontal stacker, this object is achieved according to the invention by the features of patent claim 1. The main advantage that can be achieved with the invention is that the considerable length of the package pressing tongs is used to increase the performance of the flap feeder.

Dadurch kann die Zeitspanne zwischen zwei aufeinanderfolgenden Beschickungsvorgängen von etwa einer Viertelstunde auf über eine Stunde verlängert werden.As a result, the time span between two successive loading processes can be extended from about a quarter of an hour to over an hour.

Ein weiterer Vorteil besteht darin, dass die Lagerung der Zange gleichzeitig als Halterung für den Klappenanleger dient, so dass sich eine einfachere Bauweise des Klappenanlegers ergibt. Ausserdem bietet die erfindungsgemässe Lösung den Vorteil, dass der Klappenanleger in die Zange von bereits bestehenden Staplern auch nachträglich integriert werden kann.Another advantage is that the storage of the pliers also serves as a holder for the flap feeder, resulting in a simpler construction of the flap feeder. In addition, the solution according to the invention offers the advantage that the flap feeder can also be retrofitted into the tongs of existing forklifts.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Merkmalen der abhängigen Patentansprüche.Further refinements of the invention result from the features of the dependent claims.

In Patentanspruch 2 ist eine Ausgestaltung des Klappenanlegers angegeben, bei der sich praktisch die ganze zwischen den Zangenschenkeln vorgesehene Breite zur Aufnahme der Klappen anwenden lässt.In claim 2, an embodiment of the flap feeder is specified, in which practically the entire width provided between the tong legs can be used for receiving the flaps.

In Patentanspruch 3 ist eine einfache und zuverlässig arbeitende Konstruktion zur Halterung und zur Zuführung der Klappen angegeben.In claim 3, a simple and reliable working construction for holding and feeding the flaps is specified.

In Patentanspruch 4 ist eine Ausführungsform der Gleit- und Halteführungen der Klappen angegeben, die eine einfache und zuverlässige Überführung der Klappen auf die Zangenschenkel gewährleistet.In claim 4 an embodiment of the slide and holding guides of the flaps is specified, which ensures a simple and reliable transfer of the flaps to the pliers legs.

Die Merkmale der Patentansprüche 5 und 6 beziehen sich auf eine einfache und zuverlässig arbeitende Ausführungsform der Ausziehmittel der in die Zangenschenkel zu überführenden Klappen.The features of claims 5 and 6 relate to a simple and reliable working embodiment of the pull-out means of the flaps to be transferred into the tong legs.

Die Erfindung wird im Anschluss anhand eines schematisch in den beiliegenden Zeichnungen dargestellten Beispiels näher beschrieben. Es zeigen:

  • Figur 1 einen waagerechten Staplers in einer Seitensicht;
  • Figur 2 im Detail eine Seitenansicht der Paket-Presszange mit sich in Ruhestellung befindlichem integriertem Klappenanleger;
  • Figur 3 als Detail gemäss Figur 2 die in den offenen Schenkeln der Zange herabgelassenen endseitigen Klappen;
  • Figur 4 als Detail gemäss Figur 2 und 3 die geschlossene Zange; und
  • Figur 5 einen Querschnitt durch eine Backe der Zange.
The invention is described in more detail below with reference to an example schematically shown in the accompanying drawings. Show it:
  • Figure 1 shows a horizontal stacker in a side view;
  • FIG. 2 shows in detail a side view of the package pressing tongs with the integrated flap feeder in the rest position;
  • 3 shows, as a detail according to FIG. 2, the end flaps lowered in the open legs of the pliers;
  • Figure 4 as a detail according to Figures 2 and 3, the closed pliers; and
  • Figure 5 shows a cross section through a jaw of the pliers.

In Figur 1 ist ein bekannter waagerechter Stapler 1 mit einem Förderweg 2 eines nicht gezeigten Stromes von schuppenartig angeordneten Heftlagen schematisch dargestellt.In Figure 1, a known horizontal stacker 1 is schematically shown with a conveyor path 2 of a stream, not shown, of stapled layers arranged in a scale.

Mit dem Bezugszeichen 3 ist ein Schwingteppich zum Einführen des Heftlagenstromes in den Paketbildungsbereich 4 bezeichnet. Die Zange, mit der die fertigen Pakete gepresst werden, um die Luft aus den Heftlagen vor dem anschliessenden Bindevorgang zu entfernen, ist insgesamt mit 5 bezeichnet.Reference number 3 denotes an oscillating carpet for introducing the booklet stream into the package formation area 4. The pliers with which the finished packages are pressed in order to remove the air from the booklet layers before the subsequent binding process are designated by 5 in total.

Mit dem Bezugszeichen 6 ist der Bereich bezeichnet, in dem gewöhnlich ein nicht dargestellter Klappenanleger angeordnet ist.Reference number 6 denotes the area in which a flap feeder (not shown) is usually arranged.

Wie aus Figur 1 ersichtlich, ist der Bereich 6 oberhalb des Paketbildungsbereich 4 ziemlich kurz. Die hier angeordneten Klappenanleger weisen daher die einleitend geschilderten Nachteile auf.As can be seen from FIG. 1, the area 6 above the packet formation area 4 is quite short. The flap feeders arranged here therefore have the disadvantages described in the introduction.

Die Erfindung sieht nun vor, den Klappenanleger in die Zange 5 zu integrieren, ohne die Konstruktion des betreffenden Staplers im wesentlichen verändern zu müssen.The invention now provides for the flap feeder to be integrated into the pliers 5 without having to essentially change the construction of the stacker in question.

Die Figuren 2 bis 4 zeigen, dass im dargestellten Beispiel der Klappenanleger 8 zwei Seitenwände 9, 10 zur Auflage der aus einem entsprechenden Klappenpaket 11, 12 herauszunehmenden Klappen 13 aufweist. Die beiden Pakete 11 und 12 sind auf Trag-und Förderbahnen 15 und 16 angeordnet, die zum Beispiel aus Umlenkrollen 17, 18 und 19, 20 umgelenkten Riemen bestehen. Die Rollen 17, 19 an der Seite der Seitenwände 9, 10 sind als Walzen ausgeführt, die einen nicht dargestellten Freilauf aufnehmen.FIGS. 2 to 4 show that in the example shown the flap feeder 8 has two side walls 9, 10 for supporting the flaps 13 to be removed from a corresponding flap package 11, 12. The two packages 11 and 12 are open Carrier and conveyor tracks 15 and 16 are arranged, which consist for example of deflection rollers 17, 18 and 19, 20 deflected belts. The rollers 17, 19 on the side of the side walls 9, 10 are designed as rollers that receive a freewheel, not shown.

Der Freilauf steht auf der einen Seite mit der Walze 17, 19 und auf der anderen Seite mit einem Hebel 21, 22 in Wirkverbindung.The freewheel is operatively connected on one side to the roller 17, 19 and on the other side to a lever 21, 22.

Die Hebel 21, 22 sind über eine Zugstange 23 miteinander verbunden, die wenigstens eine bzw. - wie im dargestellten Fall - zwei Antriebs- oder Schubvorrichtungen 24 enthält, wobei in diesem Beispiel eine Kolben-Zylinder-Einheit gewählt wurde. Beim Ausschwenken der Hebel 21, 22 findet ein Vorschub der Pakete 11, 12 nach der jeweiligen Seitenwand 9, 10 hin statt.The levers 21, 22 are connected to one another via a pull rod 23 which contains at least one or — as in the case shown — two drive or push devices 24, a piston-cylinder unit being selected in this example. When the levers 21, 22 are pivoted out, the packets 11, 12 are advanced towards the respective side wall 9, 10.

Um die Endklappen auf die Schenkel 25, 26 der Zange 5 abzusenken, sind ausserhalb der Seitenwände 9, 10 ähnlich ausgebildete Ausziehmittel 29, 30 am Tragwerk oder Gestell 28 der Zange befestigt. Die Ausziehmittel 29, 30 weisen jeweils einen Zahn 31, 32 auf, der an einer an der nicht dargestellten Kolbenstange der Kolben-Zylinder-Einheiten 34, 35 befestigten Platte 33, 34, angeordnet ist.In order to lower the end flaps onto the legs 25, 26 of the pliers 5, similarly designed pull-out means 29, 30 are fastened to the supporting structure or frame 28 of the pliers outside the side walls 9, 10. The pull-out means 29, 30 each have a tooth 31, 32 which is arranged on a plate 33, 34 attached to the piston rod of the piston-cylinder units 34, 35, not shown.

Um Platz zu sparen, werden vorteilhafterweise bekannte Kolben-Zylinder-Einheiten ohne Schaft benutzt. Der bewegliche Kolben der Kolben-Zylinder-Einheiten 29, 30 ist zweckmässig an einer nicht weiter geschilderten Gewindespindel angeschraubt, die durch einen Motor oder eine Kurbel 37, 38 zum Positionieren des Zahnes 31, 32 in Abhängigkeit von der Höhe der zu überführenden Klappen 13 angetrieben wird.In order to save space, known piston-cylinder units without a shaft are advantageously used. The movable piston of the piston-cylinder units 29, 30 is expediently screwed to a threaded spindle, not further described, which is driven by a motor or a crank 37, 38 for positioning the tooth 31, 32 depending on the height of the transferring flaps 13 is driven.

Damit die Klappen 13 richtig überführt und an den Schenkeln 25, 26 der Zange festgehalten werden, sind Führungen 47 vorgesehen, wie es zum Beispiel in der Schnittansicht von Figur 5 schematisch dargestellt ist.So that the flaps 13 are transferred correctly and held on the legs 25, 26 of the pliers, guides 47 are provided, as is shown schematically, for example, in the sectional view in FIG.

Die Klappen 13 gleiten in eine Aufnahme 39, die durch an der Stelle 42, 43 angelenkte Seitenflügel 40, 41 gebildet ist, die frei drehbar sind und durch Federn 44, 45 in Schließstellung vorsgespannt sind. Die erwähnten, insgesamt mit 47 bezeichneten Führungen estrecken sich vom unteren Rand der Seitenwände 9, 10 bis zu den Schenkeln 25, 26, wobei diese Führungen im Bereich des oberen Randes des beweglichen Schenkels 25 unterbrochen sind. Die Gelenkflügel 40, 41 sind wenigstens auf Höhe der Schenkel 25, 26 vorgesehen, um das Ausziehen der Klappen nach erfolgtem Festbinden zu gestatten.The flaps 13 slide into a receptacle 39, which is formed by side wings 40, 41 articulated at the point 42, 43, which can be freely rotated and are prestressed in the closed position by springs 44, 45. The mentioned guides, designated overall by 47, extend from the lower edge of the side walls 9, 10 to the legs 25, 26, these guides being interrupted in the region of the upper edge of the movable leg 25. The articulated wings 40, 41 are provided at least at the level of the legs 25, 26 in order to allow the flaps to be pulled out after the binding has taken place.

Mit dem Bezugszeichen 50 ist der Raum für die aufeinander-folgenden Beschickunsvorgänge der Klappen bezeichnet.The reference numeral 50 designates the space for the successive loading processes of the flaps.

Dieser Raum ist vorteilhafterweise für die Bedienungsperson leicht zugänglich. Bekannte, nicht dargestellte Mittel stehen zum richtigen senkrechten Positionieren der diesem Beschickungsraum 50 zugekehrten Klappen zur Verfügung.This space is advantageously easily accessible to the operator. Known means, not shown, are available for the correct vertical positioning of the flaps facing this loading space 50.

Die Ausziehzähne 31, 32 sind als Sperrnocken ausgebildet, und zwar so, dass sie bei der Abwärtsbewegung bzw. beim Ausziehen der Klappenlage fest angeordnet sind, während sie beim Rücklauf mit nach unten gerichteter Spitze schwingen, um die Seitenwände 9, 10 überschreiten zu können. Das Positionieren der Zähne erfolgt selbsttätig durch ihr eigenes Gewicht.The extraction teeth 31, 32 are designed as locking cams, in such a way that they are fixedly arranged during the downward movement or when the valve position is extracted, while they are in return swing with the tip pointing downwards in order to be able to cross the side walls 9, 10. The teeth are positioned automatically by their own weight.

Die Arbeitsweise des erfindungsgemässen in der Zange integrierten Klappenanlegers 8 wird nachstehend beschrieben:The operation of the flap feeder 8 integrated in the pliers according to the invention is described below:

Nach der bekannten Überführung eines fertigen Pakets 51 in die aus der Zange 5 bestehende Presstation, werden die Kolben-Zylinder-Einheiten 34, 35 zum Absenken der Ausziehzähne 31, 32 angetrieben. Bei ihrer Abwärtsbewegung kommen die Zähne 31 mit dem oberen Rand der an der Seitenwand 9, 10 anliegenden Klappe 13 in Eingriff und nehmen sie an den Führungen 47 entlang nach unten mit, bis die Klappen 13 auf die Zangenschenkel 25, 26 positioniert werden, sieh Figur 3.After the known transfer of a finished package 51 into the pressing station consisting of the pliers 5, the piston-cylinder units 34, 35 are driven to lower the extraction teeth 31, 32. During their downward movement, the teeth 31 come into engagement with the upper edge of the flap 13 lying against the side wall 9, 10 and take them along along the guides 47 until the flaps 13 are positioned on the pliers legs 25, 26, see FIG 3rd

Anschliessend laufen die Zähne 31 während der Aufwärtsbewegung an den Seitenwänden 9, 10 entlang nach unten schwingender Spitze zurück und nehmen dann aufgrund ihres Eigengewichtes die ursprüngliche, waagerechte Lage selbsttätig wieder ein. Der von den herausgezogenen Klappen frei gelassene Raum wird prompt durch die vorgeschobenen Pakete 11, 12 wieder gefällt. Der Vorschub erfolgt durch die Bewegung, mit der sich die Kolben-Zylinder-Einheiten 24 ausbreiten. Diese Bewegung löst das Ausschwenken der den Freiläufen der Walzen 17, 19 zugeordneten Hebel 21 aus, wodurch sich die Riemen der Tragbahnen 15, 16 in Pfeilrichtung verschieben, siehe Figur 2.Subsequently, the teeth 31 run backwards along the downwardly swinging tip during the upward movement and then automatically assume the original, horizontal position again due to their own weight. The space left free of the flaps pulled out is promptly felled again by the advanced packets 11, 12. The feed takes place through the movement with which the piston-cylinder units 24 spread. This movement triggers the pivoting out of the levers 21 assigned to the freewheels of the rollers 17, 19, as a result of which the belts of the support tracks 15, 16 shift in the direction of the arrow, see FIG. 2.

Nach diesem Vorschub werden die Kolben-Zylinder-Einheiten 24 eingezogen und die Hebel 21, 22 der Freiläufe werden nach innen geschwenkt. Nach dieser Schwenkbewegung, die folglich im Leerlauf stattfindet, sind die Kolben-Zylinder-Einheiten 24 wieder für den nächsten Vorschub bereit. Nach dem Schliessen des beweglichen Schenkels 25 und dem Verschieben des Pakets 51 gegen den festen Schenkel 26, werden die bekannten Gabeln zur Überführung des Pakets zurückgezogen und die Zange 5 wird mit dem Paket 51 auf bekannte Weise zur Festbindestation überführt.After this feed, the piston-cylinder units 24 retracted and the levers 21, 22 of the freewheels are pivoted inwards. After this swiveling movement, which consequently takes place in idle mode, the piston-cylinder units 24 are again ready for the next feed. After the movable leg 25 has been closed and the package 51 has been moved against the fixed leg 26, the known forks for transferring the package are withdrawn and the pliers 5 are transferred with the package 51 to the binding station in a known manner.

Nach erfolgtem Festbinden wird die Zange geöffnet und die Zangenschenkel lassen die nunmehr am Paket gebundenen Endklappen 13 frei.After tying has been done, the pliers are opened and the pliers legs release the end flaps 13 now bound to the package.
