It is thereby achieved that, when introducing the pair of angular cuts, the cutting of the pair of angular cuts which is closest to the pivot axis of the pivotable upper punching tool is started. After a partial incision of the first pair of incisions, the incision of the second pair of incisions is started.

For this notching, an additional large force is required shortly before the punching movement ends.
  • the upper punch In order to be able to apply these large forces, the upper punch must be operated with a relatively long actuating lever. Furthermore, the strapping device and in particular the base plate engaging under the strapping must also be made relatively strong in order to withstand the forces that occur.

Description

Die Erfindung betrifft eine Bandumreifungsvorrichtung mit einer ein Spannrad aufweisenden Spanneinrichtung zum Spannen eines von einer Vorratsrolle abziehbaren und um ein Packstück gelegten Stahlbandes mit einer ein feststehendes unteres Stanzwerkzeug und ein die Stanzbewegung ausführendes oberes Stanzwerkzeug aufweisenden Verschlußeinrichtung zum Verbinden der sich überlappenden Enden des Umreifungsstahlbandes mit mindestens zwei in Längsrichtung des Umreifungsstahlbandes hintereinanderliegenden Winkeleinschnittpaaren, wobei das die Stanzbewegung ausführende obere Stanzwerkzeug mit einem einen früheren Einschnittbeginn an einem Einschnittpaar als am benachbarten Einschnittpaar bewirkenden Schwenklager versehen ist.The invention relates to a strap strapping device with a tensioning device having a tensioning wheel for tensioning a steel strap that can be pulled off a supply roll and placed around a package with a fixed lower punching tool and a closing device that performs the punching movement and connects the overlapping ends of the strapping steel strap with at least two in the longitudinal direction of the strapping steel band, successive angular incision pairs, the upper punching tool performing the punching movement being provided with an earlier incision start on one incision pair than on the adjacent incision pair causing pivot bearing.

Bei dieser aus der GB-A-20 82 977 bekannten Bandumreifungsvorrichtung ist das Umreifungsband um das Packstück zu legen und dann die Bandumreifungsvorrichtung auf die sich überlappenden Bandenden aufzuschieben. Die Bandumreifungsvorrichtung weist hierzu eine seitlich offene Aufnahme auf, so daß die sich überlappenden Bandenden zwischen einer Grundplatte, die das untere Stanzwerkzeug aufweist, und dem die Stanzbewegung ausführenden oberen Stanzwerkzeug angeordnet wird. Das Spannrad der Spanneinrichtung ist ebenfalls oberhalb der sich überlappenden Bandenden des Umreifungsbandes angeordnet, so daß zunächst das Umreifungsband um das Packstück gespannt werden kann. Nach dem Spannen des Umreifungsbandes wird die Verschlußeinrichtung zum Verbinden der sich überlappenden Enden des Umreifungsstahlbandes betätigt. Als Verschluß werden dabei drei in Längsrichtung des Umreifungsbandes hintereinanderliegende Winkeleinschnittpaare in die sich überlappenden Bandenden des Umreifungsbandes eingebracht. Die miteinander in Wirkverbindung tretenden Stanzwerkzeuge weisen dabei jeweils in Einschnittrichtung bogenförmig verlaufende Schnittkanten auf, so daß beim Einbringen der Winkeleinschnittpaare jeweils die zwischen jedem Winkeleinschnittpaar liegenden mittleren Stege nach oben aus der Bandebene und die durch die Winkeleinschnittpaare gebildeten seitlichen Stege nach unten aus der Bandebene herausgewölbt werden. Nach dem Abschneiden des überschüssigen, zur Vorratsrolle führenden Umreifungsbandes wird dann die Spanneinrichtung gelöst, und die sich überlappenden Bandenden verschieben sich etwas gegeneinander, so daß die durch die Winkeleinschnitte gebildeten vorspringenden Ecken des oben liegenden Bandendes und des unten liegenden Bandendes sich hintergreifen und verhaken.In this strap strapping device known from GB-A-20 82 977, the strapping strap is to be placed around the package and then the strap strapping device is pushed onto the overlapping strap ends. For this purpose, the band strapping device has a laterally open receptacle, so that the overlapping tape ends are arranged between a base plate, which has the lower punch, and the upper punch, which performs the punching movement. The tensioning wheel of the tensioning device is also arranged above the overlapping strap ends of the strapping strap, so that the strapping strap can first be tensioned around the package. After the strapping has been tensioned, the closure device is actuated to connect the overlapping ends of the strapping steel strap. As a closure, three pairs of angular incisions lying one behind the other in the longitudinal direction of the strapping band are introduced into the overlapping band ends of the strapping band. The punching tools, which are in operative connection with one another, each have arcuate cutting edges in the direction of incision, so that when the pairs of angular incisions are introduced, the middle webs between each pair of angular incisions are arched upward out of the band plane and the lateral webs formed by the pair of angular incisions are arched downward out of the band plane . After the excess strapping leading to the supply roll has been cut off, the tensioning device is then released and the overlapping strap ends move somewhat against one another, so that the protruding corners of the top strap end and the bottom strap end formed by the angular cuts reach behind and hook.

Zum Einbringen eines Winkeleinschnittpaares in die sich überlappenden Bandenden ist an dem die Stanzbewegung ausführenden oberen Stanzwerkzeug eine Kraft aufzubringen, die jedoch über die gesamte Einschneidbewegung nicht gleich groß ist. Die größte Kraft ist zu Beginn des Einschneidens eines Einschnittpaares erforderlich, da dann die flaschen Rücken der in Einschnittrichtung bogenförmig verlaufenden Schnittkanten zugleich über eine größere Länge in die sich überlappenden Bandenden einzubringen sind. Bei der weiteren Einschnittbewegung eines jeden Einschnittpaares erfolgt dann ein einfaches Scheren, wozu weniger Kraft erforderlich ist. Damit beim Einbringen von drei Einschnittpaaren, die in Umfangsrichtung des Umreifungsbandes hintereinander liegen, die Höchstwerte der erforderlichen Kräfte nicht zusammenfallen, ist bei der bekannten Bandumreifungsvorrichtung, das die Stanzbewegung ausführende obere Stanzwerkzeug an einem Schwenkhebel angeordnet, wobei die Schwenkachse des Schwenkhebels quer zur Bandrichtung verläuft und mindestens angenähert in der Wirkebene der Werkzeugteile angeordnet ist und zwar an der der Spanneinrichtung abgekehrten Seite der Stanzwerkzeuge. Dadurch wird erreicht, daß beim Einbringen der Winkeleinschnittpaare zunächst mit dem Einschneiden des Winkeleinschnittpaares begonnen wird, welches der Schwenkachse des schwenkbaren oberen Stanzwerkzeuges am nächsten liegt. Nach einem teilweisen Einschneiden des ersten Einschnittpaares wird mit dem Einschneiden des zweiten Einschnittpaares begonnen. Nach einem teilweisen Einschneiden des zweiten Einschnittpaares wird mit dem Einschneiden des dritten Einschnittpaares begonnen. Bis zum Ende der Schwenkbewegung des schwenkbar gelagerten oberen Stanzwerkzeuges wird dann jedoch an allen Einschnittpaaren weiter geschnitten, so daß auch hierzu eine verhältnismäßig große Kraft erforderlich ist. Hinzu kommt auch noch, daß kurz vor Beendigung der Schwenkbewegung des schwenkbar gelagerten oberen Stanzwerkzeuges ein an dem schwenkbar gelagerten oberen Stanzwerkzeug angebrachtes Kerbmesser wirksam wird. Das Kerbmesser muß sich dabei in das oben liegende Bandende einpressen, da das darunter liegende Bandende von der die sich überlappenden Bandenden untergreifenden Grundplatte der Bandumreifungsvorrichtung abgestützt wird. Für dieses Abkerben ist kurz vor Beendigung der Stanzbewegung nochmals eine zusätzliche große Kraft erforderlich. Um diese großen Kräfte aufbringen zu können, muß das obere Stanzwerkzeug mit einem verhältnismäßig langen Betätigungshebel betätigt werden. Weiterhin muß auch die Bandumreifungsvorrichtung und insbesondere die die Umreifungsbänder untergreifende Grundplatte verhältnismäßig kräftig ausgebildet werden, um den auftretenden Kräften standzuhalten. Durch die Anordnung des oberen Stanzwerkzeuges an einem Schwenkhebel, dessen Schwenkachse quer zur Bandrichtung verläuft und mindestens angenähert in der Winkelebene der Werkzeugteile angeordnet ist, ergibt sich zwangsläufig auch noch der Nachteil, daß die Stanzbewegung des oberen Stanzwerkzeuges in einem festen Anschlag begrenzt werden muß, damit sichergestellt ist, daß alle Einschnittpaare gleich tief und gleich lang ausgebildet werden, um die Zugbelastung auf alle Einschnitte gleichmäßig zu verteilen. Diese genau festgelegte Begrenzung der Stanzbewegung des oberen Stanzwerkzeuges erfordert jedoch eine genaue Dimensionierung und Anordnung des Kerbmessers, damit das obere Bandende bei dem begrenzten Stanzhub abgetrennt wird.To introduce a pair of angular incisions into the overlapping ends of the tape, a force must be applied to the upper punching tool that performs the punching movement, but this force is not the same over the entire cutting movement. The greatest force is required at the beginning of the incision of a pair of incisions, since then the flanky backs of the cutting edges which are curved in the incision direction are at the same time to be introduced into the overlapping band ends over a greater length. With the further incision movement of each incision pair, simple shearing then takes place, for which less force is required. So that the maximum values of the required forces do not coincide when three pairs of incisions are made in the circumferential direction of the strapping, the upper punching tool performing the punching movement is arranged on a pivot lever in the known strap strapping device, the pivot axis of the pivot lever extending transversely to the strap direction and is arranged at least approximately in the active plane of the tool parts, specifically on the side of the punching tools facing away from the clamping device. It is thereby achieved that, when introducing the pair of angular cuts, the cutting of the pair of angular cuts which is closest to the pivot axis of the pivotable upper punching tool is started. After a partial incision of the first pair of incisions, the incision of the second pair of incisions is started. After the second incision pair has been partially incised, the incision of the third incision pair is started. Until the end of the pivoting movement of the pivotably mounted upper punching tool, however, all pairs of cuts are cut further, so that a relatively large force is also required for this. In addition, there is also the fact that shortly before the end of the pivoting movement of the pivotably mounted upper punch a notch knife attached to the pivotably mounted upper punching tool takes effect. The notch knife must press into the upper end of the band, since the end of the band underneath is supported by the base plate of the strapping device, which engages under the overlapping ends of the band. For this notching, an additional large force is required shortly before the punching movement ends. In order to be able to apply these large forces, the upper punch must be operated with a relatively long actuating lever. Furthermore, the strapping device and in particular the base plate engaging under the strapping must also be made relatively strong in order to withstand the forces that occur. The arrangement of the upper punch on a pivot lever, the pivot axis of which extends transversely to the belt direction and is arranged at least approximately in the angular plane of the tool parts, inevitably also has the disadvantage that the punching movement of the upper punch must be limited in a fixed stop so that It is ensured that all pairs of cuts are of the same depth and length in order to distribute the tensile load evenly over all cuts. However, this precisely defined limitation of the punching movement of the upper punching tool requires precise dimensioning and arrangement of the notch knife so that the upper band end is cut off during the limited punching stroke.

Der Erfindung liegt die Aufgabe zugrunde, eine Bandumreifungsvorrichtung der eingangs erläuterten Art weiter zu verbessern, und insbesondere die am oberen, die Stanzbewegung ausführenden Stanzwerkzeug aufzubringende Gesamtkraft klein zu halten.The invention has for its object to further improve a strapping device of the type described in the introduction, and in particular to keep the total force to be exerted on the upper punching tool performing the punching movement small.

Diese Aufgabe ist mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.

Die dem unteren Stanzwerkzeug zugekehrte Arbeitsfläche des oberen Stanzwerkzeuges kann in Anpassung an seine abrollende Bewegung bogenförmig ausgebildet sein. Dadurch wird in einfacher Weise erreicht, daß trotz der abrollenden Stanzbewegung des oberen Stanzwerkzeuges die Auswölbungen des Mittelsteges und der Seitenstege an jedem Einschnittpaar gleich groß erfolgen und die Einschnittlängen an jedem Einschnittpaar gleich lang sind.The working surface of the upper punching tool facing the lower punching tool can be designed to be curved in adaptation to its rolling motion. It is thereby achieved in a simple manner that, despite the rolling punch movement of the upper punch, the bulges of the central web and the side webs are the same on each pair of cuts large and the incision lengths are the same length on each incision pair.

Das obere Stanzwerkzeug kann an seinem der Arbeitsfläche abgekehrten Ende einen Durchbruch zur formschlüssigen Aufnahme eines mit einer Welle antreibbaren Exzenters aufweisen und an seinem die Arbeitsfläche aufweisenden Ende mit einem seitlichen Ansatz in einer Nut geführt sein, die lotrecht zu Arbeitsfläche des unteren Stanzwerkzeuges verläuft, wobei die von dem seitlichen Ansatz gebildete Schwenkachse etwa in der Ebene der Arbeitsfläche des oberen Stanzwerkzeuges angeordnet ist. Das die Stanzbewegung aus führende obere Stanzwerkzeug ist somit in einfacher Weise nach Art einer Schubschwinge ausgebildet und kann somit in einfacher Weise die gewünschte Zustellbewegung und die Abrollbewegung ausführen. Da das obere Stanzwerkzeug formschlüssig mit einem Durchbruch einen Exzenter der antreibbaren Welle aufnimmt, erfolgt formschlüssig nicht nur die Zustellbewegung des oberen Stanzwerkzeuges zu dem unteren Stanzwerkzeug, sondern auch die Rückstellung des oberen Stanzwerkzeuges in die Grundstellung, in der das obere Stanzwerkzeug mit einem Abstand zum unteren Stanzwerkzeug angeordnet ist, damit die sich überlappenden Bandenden zwischen die Stanzwerkzeuge eingeführt und nach dem Einstanzen der Winkeleinschnittpaare wieder von den Stanzwerkzeugen entfernt werden können. Das die Arbeitsfläche aufweisende Ende des oberen Stanzwerkzeuges ist mit einem seitlichen Ansatz in einer Nut des Gehäuses geführt, die lotrecht zur Arbeitsfläche des unteren Stanzwerkzeuges verläuft. Dadurch wird in einfacher Weise das die Arbeitsfläche aufweisende Ende des oberen Stanzwerkzeuges derart geführt, daß die beiden Stanzwerkzeuge zuverlässig zusammenwirken können. Die von dem seitlichen Ansatz des oberen Stanzwerkzeuges gebildeten Schwenkachse ist etwa in der Ebene der Arbeitsfläche des oberen Stanzwerkzeuges angeordnet, so daß beim bestimmungsgemäßen Eingriff der Arbeitsfläche des oberen Stanzwerkzeuges in die Oberfläche der sich überlappenden Bandenden keine Verschiebung in Längsrichtung des Bandes erfolgt.The upper punch can have an opening at its end facing away from the work surface for the positive reception of an eccentric that can be driven with a shaft and can be guided at its end having the work surface with a lateral attachment in a groove that runs perpendicular to the work surface of the lower punch tool, the pivot axis formed by the lateral extension is arranged approximately in the plane of the working surface of the upper punch. The upper punching tool guiding the punching movement is thus designed in a simple manner in the manner of a thrust arm and can thus carry out the desired infeed movement and the rolling movement in a simple manner. Since the upper punching tool receives an eccentric of the drivable shaft in a form-fitting manner, not only does the upper punching tool move towards the lower punching tool in a form-fitting manner, but also the upper punching tool is returned to the basic position in which the upper punching tool is at a distance from the lower one Punching tool is arranged so that the overlapping tape ends can be inserted between the punching tools and removed from the punching tools again after the pairs of angular cuts have been punched in. The end of the upper punch that has the work surface is guided with a lateral shoulder in a groove in the housing that runs perpendicular to the work surface of the lower punch. As a result, the end of the upper punching tool which has the working surface is guided in a simple manner in such a way that the two punching tools can cooperate reliably. The pivot axis formed by the lateral attachment of the upper punch is approximately in the plane of the working surface of the upper punch arranged so that when the working surface of the upper punching tool engages as intended in the surface of the overlapping tape ends, there is no displacement in the longitudinal direction of the tape.

Die den Antriebsexzenter für das obere Stanzwerkzeug aufweisende Welle kann lotrecht über der Längsmitte des unteren Stanzwerkzeuges angeordnet sein und die den seitlichen Ansatz des oberen Stanzwerkzeuges führende Nut kann ebenfalls inder Längsmitte des unteren Stanzwerkzeuges lotrecht verlaufen. Dadurch ist in einfacher Weise das als Schubschwinge wirkende obere Stanzwerkzeug zentrisch zur Längsmitte des aus mehreren Einschnittpaaren bestehenden Verschlusses angeordnet.The shaft having the drive eccentric for the upper punch can be arranged perpendicularly over the longitudinal center of the lower punch and the groove leading the lateral attachment of the upper punch can also run perpendicularly in the longitudinal center of the lower punch. As a result, the upper punching tool, which acts as a thrust arm, is arranged in a simple manner centered on the longitudinal center of the closure consisting of several pairs of cuts.

Die zum bestimmungsgemäßen Stanzvorgang des oberen Stanzwerkzeuges erforderliche Schwenkbewegung des an der Antriebswelle vorgesehenen Exzenters kann auf Teilbereiche zu beiden Seiten der unteren Totpunktstellung begrenzt sein. Zum bestimmungsgemäßen Gebrauch der Bandumreifungsvorrichtung muß somit die den Exzenter aufweisende Antriebswelle nicht um 360 Grad gedreht werden, was mit einem an der Welle angebrachten Betätigungshebel ohnehin nicht erzielt werden kann. Um mit dem oberen Stanzwerkzeug die erforderliche Stanzbewegung durchführen zu können, ist der Exzenter mit der Antriebswelle lediglich im Bereich seiner unteren Totpunktstellung zu bewegen und zwar zu beiden Seiten der unteren Totpunktstellung. Im unmittelbaren Nahbereich der unteren Totpunktstellung erfolgt dabei insbesondere die Abrollbewegung, während mit einem größer werdenden Abstand zur unteren Totpunktstellung auch die erforderliche Zustellbewegung bzw. Abzugsbewegung des oberen Stanzwerkzeuges zum unteren Stanzwerkzeug bewirkt wird.The swiveling movement of the eccentric provided on the drive shaft for the intended punching operation of the upper punching tool can be limited to partial areas on both sides of the bottom dead center position. For the intended use of the strapping device, the drive shaft having the eccentric does not have to be rotated through 360 degrees, which cannot be achieved with an actuating lever attached to the shaft anyway. In order to be able to carry out the required punching movement with the upper punching tool, the eccentric with the drive shaft is only to be moved in the area of its bottom dead center position, namely on both sides of the bottom dead center position. In the immediate vicinity of the lower dead center position, the rolling movement takes place in particular, while the required infeed movement or pull-off movement of the upper punching tool to the lower punching tool is also effected with an increasing distance from the bottom dead center position.

Beim bestimmungsgemäßen Stanzvorgang können die Stanzwerkzeuge zuerst an dem einzuschneidenden Einschnittpaar wirksam werden, welches in Umfangsrichtung am weitesten von der Spanneinrichtung entfernt ist und zuletzt an dem einzuschneidenden Einschnittpaar, welches in Umfangsrichtung am wenigsten von der Spanneinrichtung entfernt ist. Die Spanneinrichtung übt insbesondere in seiner Spannstellung eine Kraft auf die Grundplatte aus, da das Spannrad von oben auf die sich überlappenden unterseitig von der Grundplatte abgestützten Bandenden drücktt. Die auf die Grundplatte ausgeübte Kraft ist dabei abhängig von der Bandspannung. Durch den Beginn des Einschneidvorganges an dem Einschnittpaar, welches am weitesten von der Spanneinrichtung entfernt ist, erfolgt die durch den Einstanzvorgang an der Grundplatte bewirkte Belastung in großer Entfernung zu den vom Spannrad erzeugten Belastung, so daß diese Belastungen leicht von der Grundplatte aufgenommen werden können. Beim weiteren Einschneidvorgang wandert die durch den Einschneidvorgang bewirkte Belastung der Grundplatte immer näher zu der belasteten Stelle, deren Belastung vom Spannrad verursacht wird. Durch das weitere Einbringen der Einschnitte wird jedoch die im Umreifungsband herrschende Bandspannung bereits etwas von den Einschnitten und den in den Einschnitten hineinragenden Stanzwerkzeuge aufgenommen, so daß die Spanneinrichtung nicht mehr die gesamte Bandspannung aufnehmen muß. Dadurch wird jedoch die von der Spanneinrichtung auf die Grundplatte bewirkte Belastung kleiner, so daß dann auch beim Einbringen des Einschnittpaares, welches der Spannvorrichtung benachbart ist, keine sehr große Gesamtbelastung mehr auf die Grundplatte ausgeübt wird.During the intended punching process, the punching tools can first be effective on the pair of incisions to be cut, which is furthest from the clamping device in the circumferential direction, and lastly on the pair of incisions to be cut, which is the least distant from the clamping device. The tensioning device exerts a force on the base plate, in particular in its tensioned position, since the tensioning wheel presses from above onto the overlapping belt ends supported on the underside by the base plate. The force exerted on the base plate depends on the belt tension. By the beginning of the cutting process on the pair of cuts, which is furthest away from the clamping device, the stress caused by the punching process on the base plate occurs at a great distance from the load generated by the tensioning wheel, so that these loads can be easily absorbed by the base plate. During the further cutting process, the load on the base plate caused by the cutting process moves ever closer to the stressed point, the load of which is caused by the tensioning wheel. By further making the incisions, however, the band tension prevailing in the strapping band is already somewhat absorbed by the incisions and the punching tools protruding into the incisions, so that the tensioning device no longer has to absorb the entire band tension. As a result, however, the load caused by the tensioning device on the base plate becomes smaller, so that even when the pair of incisions, which is adjacent to the tensioning device, is introduced, no very large total load is exerted on the base plate.

Der seitliche Ansatz des oberen Stanzwerkzeuges kann eine runde Querschnittsfläche aufweisen und in eine Bohrung eines in der Nut geführten Gleitsteines eingreifen. Mit dem Eingriff des zylindrischen Ansatzes in die Bohrung des Gleitsteines und der Führung des Gleitsteines in der Nut wird somit in einfacher und zuverlässiger Weise eine verschleißarme Führung für das die Arbeitsfläche aufweisende Ende des oberen Stanzwerkzeuges geschaffen.The lateral attachment of the upper punching tool can have a round cross-sectional area and engage in a bore of a sliding block guided in the groove. With the intervention of the cylindrical extension into the bore of the sliding block and the guide of the sliding block in the groove, a low-wear guide for the end of the upper punching tool having the working surface is thus created in a simple and reliable manner.

Der den zylindrischen seitlichen Ansatz des oberen Stanzwerkzeuges aufnehmende Gleitstein kann an seinem zum unteren Stanzwerkzeug gerichteten Ende mindestens einen die zwischen den beiden Stanzwerkzeugen angeordneten Umreifungsbandenden im Randbereich untergreifenden Aushebeansatz aufweisen. Mit diesen am Gleitstein vorgesehenen Aushebeansatz kann in einfacher Weise beim Rückführen des oberen Stanzwerkzeuges in die Grundstellung, in der das obere Stanzwerkzeug im Abstand zum unteren Stanzwerkzeug angeordnet ist, die sich überlappenden Bandenden nach dem Einbringen der Winkeleinschnitte aus dem unteren Stanzwerkzeug herausgezogen werden.The sliding block receiving the cylindrical lateral attachment of the upper punching tool can have at least one lifting lug, which straddles the strapping strap ends arranged between the two punching tools in the edge area, at its end facing the lower punching tool. With these lifting lugs provided on the sliding block, the overlapping tape ends can be pulled out of the lower punching tool after the upper punching tool has been arranged at a distance from the lower punching tool when the upper punching tool is returned to the basic position.

Die den Antriebsexzenter für das obere Stanzwerkzeug aufweisende Welle kann mit einem Handhebel verschwenkbar sein. Durch einfache Betätigung der Antriebswelle mit dem Handhebel kann somit das obere Stanzwerkzeug aus der Grundstellung in die Stanzstellung und aus der Stanzstellung wieder zurück in die Grundstellung überführt werden.The shaft having the drive eccentric for the upper punching tool can be pivoted with a hand lever. By simply actuating the drive shaft with the hand lever, the upper punching tool can thus be transferred from the basic position to the punching position and from the punching position back to the basic position.

Die mit dem unteren Stanzwerkzeug zusammenwirkende Arbeitsfläche des oberen Stanzwerkzeuges kann in Umreifungsrichtung zur Spanneinrichtung hin etwas verlängert sein und ein an sich bekanntes Kerbmesser zum Abtrennen des gespannten, zu einer Vorratsrolle führenden Umreifungsbandes aufweisen. Mit der Stanzbewegung des oberen Stanzwerkzeuges kann somit in einfacher Weise das überschüssige Umreifungsband, welches zur Vorratsrolle führt, von der Umreifung abgetrennt werden.The working surface of the upper punch, which interacts with the lower punch, can be somewhat extended in the strapping direction towards the tensioning device and can have a notch knife known per se for severing the tensioned strapping leading to a supply roll. With the punching movement of the upper punching tool, the excess strapping that leads to the supply roll can thus be separated from the strapping in a simple manner.

Das Kerbmesser ist dabei derart angeordnet, daß durch die Abrollbewegung der Arbeitsfläche des oberen Stanzwerkzeuges auf der Arbeitsfläche des unteren Stanzwerkzeuges das eigentliche Abkerben bewirkt wird, nachdem auch das letzte Einschnittpaar vollständig eingebracht ist.The notch knife is arranged in such a way that the actual notching is effected by the rolling movement of the working surface of the upper punching tool on the working surface of the lower punching tool after the last pair of cuts has also been made completely.

Die auf der Zeichnung dargestellte Bandumreifungsvorrichtung besteht aus einem Gehäuse 10 mit Handgriff 15 und mit einer Grundplatte 11 . Zwischen dem Gehäuse 10 und der Grundplatte 11 ist dabei ein seitlich offener Aufnahmeschlitz 12 für die sich überlappenden Bandenden eines Umreifungsbandes angeordnet. Das Umreifungsband ist um ein nicht näher dargestelltes Packstück zu legen und danach die Bandumreifungsvorrichtung mit dem Aufnahmeschlitz 12 auf die sich überlappenden Bandenden 13 aufzuschieben. Zu diesem Aufschieben der Bandumreifungsvorrichtung auf die sich überlappenden Bandenden ist eine am Gehäuse 10 schwenkbar gelagerte Spanneinrichtung 14 mit dem Hebel 17 durch Schwenken entgegen der Spannrichtung anzuheben, so daß das Spannrad 16 der Spanneinrichtung von der Grundplatte 11 frei kommt und das Einführen der sich überlappenden Bandenden 13 des Umreifungsbandes in den Aufnahmeschlitz 12 ermöglicht. Nach dem Aufsetzen der Bandumreifungsvorrichtung auf die sich überlappenden Bandenden 13 ist der Hebel 17 der Spanneinrichtung 14 loszulassen, so daß die Spanneinrichtung 14 unter der Wirkung eines nicht näher dargestellten Kraftspeichers ihre Wirkstellung einnimmt, in der das Spannrad 16 der Spanneinrichtung 14 kraftschlüssig gegen die Oberseite der sich überlappenden Bandenden 13 anlegt. Durch Drehen des Spannrades 16 mit dem Betätigungshebel 17 ist dann das Umreifungsband um das nicht näher dargestellte Packstück zu spannen. Nachdem das Umreifungsband mit der erforderlichen Spannung versehen worden ist, kann dann in die sich überlappenden Bandenden 13 des Umreifungsbandes ein Verschluß eingebracht werden.The strapping device shown in the drawing consists of a housing 10 with a handle 15 and with a base plate 11. Between the housing 10 and the base plate 11 there is a laterally open receiving slot 12 for the overlapping strap ends of a strapping strap. The strapping band is to be placed around a package (not shown in more detail) and then the band strapping device with the receiving slot 12 is pushed onto the overlapping band ends 13. For this pushing of the strap strapping device onto the overlapping strap ends is a tensioning device 14 pivotably mounted on the housing 10 with the lever 17 by pivoting against the tensioning direction to be lifted so that the tensioning wheel 16 of the tensioning device comes free from the base plate 11 and enables the overlapping strap ends 13 of the strapping strap to be inserted into the receiving slot 12. After the strap strapping device has been placed on the overlapping strap ends 13, the lever 17 of the tensioning device 14 is to be released so that the tensioning device 14 assumes its active position under the action of a force accumulator (not shown), in which the tensioning wheel 16 of the tensioning device 14 is non-positively against the top of the overlapping tape ends 13 creates. By turning the tensioning wheel 16 with the actuating lever 17, the strapping is then to be tightened around the package (not shown). After the strapping has been provided with the required tension, a closure can then be introduced into the overlapping ends 13 of the strapping.

Beim dargestellten Ausführungsbeispiel werden als Verschluß drei an sich bekannte Winkeleinschnittpaare in die sich überlappenden Bandenden 13 des Umreifungsbandes eingebracht. Die nicht näher dargestellten Winkeleinschnittpaare sind dabei in Längsrichtung des Umreifungsbandes hintereinander angeordnet. Beim Einbringen der Winkeleinschnittpaare werden zugleich mit dem Einschneiden der Einschnitte jeweils die zwischend den Einschnittpaaren liegenden mittleren Stege 18 nach oben aus der Bandebene herausgewölbt, während die durch die Einschnitte gebildeten Seitenstege 19 nach unten aus der Bandebene herausgewölbt werden. Dadurch können nach dem Lösen der Spanneinrichtung 14 die durch die Winkeleinschnitte gebildeten vorspringenden Ecken des einen Bandendes die durch die Winkeleinschnitte gebildeten vorspringenden Ecken des anderen Bandendes sich hintergreifen und verhaken.In the illustrated embodiment, three known pairs of angular incisions are introduced into the overlapping ends 13 of the strapping as a closure. The pairs of angular incisions, not shown, are arranged one behind the other in the longitudinal direction of the strapping. When the pairs of angular incisions are introduced, the central webs 18 between the pairs of incisions are simultaneously arched upwards out of the band plane while the incisions are being cut, while the side webs 19 formed by the incisions are arched downwards out of the band plane. As a result, after the tensioning device 14 has been released, the projecting corners of one band end formed by the angular incisions can engage behind and catch the projecting corners formed by the angular incisions of the other band end.

Das Einbringen der Winkeleinschnitte erfolgt mit einem unteren Stanzwerkzeug 20 und einem oberen Stanzwerkzeug 21. Das untere Stanzwerkzeug 20 ist fest an der Grundplatte 11 gehaltert, während das obere Stanzwerkzeug 21 im Gehäuse 10 angeordnet ist und die Stanzbewegung ausführt.The angle cuts are made with a lower one Punching tool 20 and an upper punching tool 21. The lower punching tool 20 is fixedly held on the base plate 11, while the upper punching tool 21 is arranged in the housing 10 and carries out the punching movement.

Das obere Stanzwerkzeug weist an seinem seiner Arbeitsfläche 22 abgekehrten Ende einen Durchbruch 23 zur formschlüssigen Aufnahme eines mit einer Welle 24 antreibbaren Exzenters 25 auf. Wie insbesondere aus der Fig. 1 ersichtlich kann die den Exzenter 25 antreibende Welle 24 mit einem Betätigungshebel 26 gedreht werden. An seinem die Arbeitsfläche 22 aufweisenden Ende ist das obere Stanzwerkzeug 21 mit einem seitlichen Ansatz 27 in einer Nut 28 geführt, die lotrecht zur Arbeitsfläche 29 des unteren Stanzwerkzeuges 20 verläuft, wobei die von dem seitlichen Ansatz 27 gebildete Schwenkachse 30 etwa in der Ebene der Arbeitsfläche 22 des oberen Stanzwerkzeuges 21 angeordnet ist. Die den Antriebsexzenter 25 für das obere Stanzwerkzeug 21 aufweisende Welle 24 ist lotrecht über der Längsmitte des unteren Stanzwerkzeuges 2o angeordnet. Die den seitlichen Ansatz 27 des oberen Stanzwerkzeuges 21 führende Nut 28 verläuft lotrecht in der Längsmitte des unteren Stanzwerkzeuges 20. Die zum bestimmungsgemäßen Stanzvorgang des oberen Stanzwerkzeuges 21 erforderliche Schwenkbewegung des an der Antriebswelle 24 vorgesehenen Exzenters 25 ist dabei auf Teilbereiche zu beiden Seiten der unteren Totpunktstellung begrenzt.At its end facing away from its working surface 22, the upper punching tool has an opening 23 for the positive reception of an eccentric 25 which can be driven by a shaft 24. As can be seen in particular from FIG. 1, the shaft 24 driving the eccentric 25 can be rotated with an actuating lever 26. At its end having the working surface 22, the upper punch 21 is guided with a lateral extension 27 in a groove 28 which runs perpendicular to the working surface 29 of the lower punch 20, the pivot axis 30 formed by the lateral extension 27 approximately in the plane of the working surface 22 of the upper punch 21 is arranged. The shaft 24 having the drive eccentric 25 for the upper punch 21 is arranged vertically above the longitudinal center of the lower punch 2o. The groove 28 which leads the lateral shoulder 27 of the upper punch 21 extends perpendicularly in the longitudinal center of the lower punch 20. The swiveling movement of the eccentric 25 provided on the drive shaft 24 for the intended punching operation of the upper punch 21 is on partial areas on both sides of the bottom dead center position limited.

Beim bestimmungsgemäßen Stanzvorgang werden die Stanzwerkzeuge 20, 21 zuerst an dem einzuschneidenden Einschnittpaar wirksam, welches in Umreifungsrichtung am weitesten von der Spanneinrichtung 14 entfernt ist. Danach wird das mittlere Einschnittpaar eingeschnitten und zuletzt das Einschnittpaar, welches in Umreifungsrichtung am wenigsten von der Spanneinrichtung 14 entfernt ist.During the intended punching process, the punching tools 20, 21 are first effective on the pair of incisions to be cut, which is furthest from the tensioning device 14 in the strapping direction. Then the middle pair of cuts is cut and finally the pair of cuts which is least of the strapping direction Clamping device 14 is removed.

Durch den Antrieb des oberen Stanzwerkzeuges 21 mit dem Exzenter 25 und der Lagerung des seitlichen Ansatzes 27 in einer senkrecht verlaufenden Nut 28 führt das obere Stanzwerkzeug 21 eine Bewegung nach Art einer Schubschwinge aus. Verschiedene beim Stanzvorgang auftretende Stellungen des oberen Stanzwerkzeuges 21 sind in den Fig. 2 bis 8 dargestellt. In der Fig. 2 ist das obere Stanzwerkzeug 21 in der Grundstellung dargestellt. Die Arbeitsfläche 22 des oberen Stanzwerkzeuges 21 ist dabei in einem solchen Abstand zur Arbeitsfläche 29 des unteren Stanzwerkzeuges 20 angeordnet, daß die sich überlappenden Bandenden zwischen die Stanzwerkzeuge 20 und 21 einführbar und nach Beendigung des Umreifungsvorganges ein Abziehen der Bandumreifungsvorrichtung von dem Umreifungsband möglich ist. Durch Betätigung des Betätigungshebels 26, der in den Fig. 2 bis 7 nicht näher dargestellt ist, wird die Welle 24 und damit auch der Exzenter 25 gedreht, wodurch das obere Stanzwerkzeug 21 eine Verschiebebewegung durchführt und dabei jedoch mit dem seitlichen Ansatz 27 in der Nut 28 des Gehäuses 10 geführt ist. In den Fig. 2 bis 7 ist der seitliche Ansatz 27 als zylindrischer Zapfen dargestellt, wobei die Längsmittellinie des zylindrischen Zapfens 27 die Schwenkachse 3o für das obere Stanzwerkzeug 21 bei dessen Bewegung bildet. Wie aus der Fig. 1 ersichtlich, kann der zylindrische seitliche Ansatz 27 des oberen Stanzwerkzeuges 21 auch in eine Bohrung 31 eines in der Nut 28 geführten Gleitsteines 32 eingreifen. Dadurch wird eine zuverlässige, verschleißarme Führung in der Nut 28 erzielt.By driving the upper punch 21 with the eccentric 25 and the mounting of the side extension 27 in a vertical groove 28, the upper punch 21 executes a movement in the manner of a thrust arm. Various positions of the upper punch 21 that occur during the punching process are shown in FIGS. 2 to 8. 2, the upper punch 21 is shown in the basic position. The working surface 22 of the upper punch 21 is arranged at such a distance from the working surface 29 of the lower punch 20 that the overlapping strap ends can be inserted between the punching dies 20 and 21 and after the strapping process the strapping device can be removed from the strapping. By actuating the actuating lever 26, which is not shown in FIGS. 2 to 7, the shaft 24 and thus also the eccentric 25 is rotated, as a result of which the upper punching tool 21 performs a displacement movement, but with the lateral extension 27 in the groove 28 of the housing 10 is guided. 2 to 7, the side extension 27 is shown as a cylindrical pin, the longitudinal center line of the cylindrical pin 27 forming the pivot axis 3o for the upper punch 21 when it is moving. As can be seen from FIG. 1, the cylindrical lateral extension 27 of the upper punch 21 can also engage in a bore 31 of a sliding block 32 guided in the groove 28. A reliable, low-wear guidance in the groove 28 is thereby achieved.

In der Fig. 3 ist das obere Stanzwerkzeug 21 in der Stellung dargestellt, in der seine Arbeitsfläche 22 gerade gegen die Oberseite der sich überlappenden Bandenden 13 zur Anlage gekommen ist, wobei die sich überlappenden Bandenden 13 auf der Arbeitsfläche 29 des unteren Stanzwerkzeuges 20 aufliegen. Dies ist die Stellung unmittelbar vor dem Beginn des eigentlichen Einstanzvorganges. Dabei ist jedoch schon ersichtlich, daß zuerst mit dem Einschneiden des Einschnittpaares begonnen wird, welches am weitesten von der Einspannvorrichtung entfernt ist.In Fig. 3, the upper punch 21 is shown in the position in which its working surface 22 just came to rest against the top of the overlapping tape ends 13 is, the overlapping tape ends 13 lie on the work surface 29 of the lower punch 20. This is the position immediately before the actual punching process begins. However, it can already be seen that the first step is to cut the incision pair which is the furthest away from the clamping device.

In der Fig. 4 ist das obere Stanzwerkzeug 21 in der Stellung dargestellt, in der noch nicht mit dem Einschneiden des mittleren Einschnittpaares begonnen wurde. Die entsprechenden bogenförmigen Vorsprünge 33,34 sind dabei gerade gegen die Oberseite und die Unterseite der sich überlappenden Bandenden 13 zur Anlage gekommen. Das erste Einschnittpaar ist dabei nahezu schon vollständig in die sich überlappenden Bandenden 13 eingebracht worden.4 shows the upper punching tool 21 in the position in which the middle pair of cuts has not yet been cut. The corresponding arcuate projections 33, 34 have just come to bear against the top and bottom of the overlapping band ends 13. The first pair of incisions has almost completely been made in the overlapping band ends 13.

In der Fig. 5 ist das obere Stanzwerkzeug 21 in der Stellung dargestellt, in der mit dem Einschneiden des dritten Einschnittpaares, welches am wenigsten von der Spanneinrichtung 14 entfernt ist, begonnen wird. Das erste Einschnittpaar ist bereits vollständig eingebracht. Das zweite Einschnittpaar ist ebenfalls fast vollständig eingebracht.5 shows the upper punching tool 21 in the position in which the cutting of the third pair of cuts, which is the least distant from the clamping device 14, is started. The first pair of incisions has already been made completely. The second pair of incisions is also almost completely inserted.

In der Fig. 6 ist das obere Stanzwerkzeug in der Stellung dargestellt, in der das dritte Einschnittpaar erst zum Teil eingeschnitten ist. Das Einschneiden des ersten und des zweiten Einschnittpaares ist dabei jedoch schon vollständig beendet. In der Fig. 7 ist das obere Stanzwerkzeug 21 in der Stellung dargestellt, in der das dritte Einschnittpaar vollständig in die sich überlappenden Bandenden eingebracht ist. Der Einschneidvorgang am ersten, zweiten und am dritten Einschnittpaar wird somit in einfacher Weise nacheinander begonnen und die Einschnittvorgänge werden auch nacheinander beendet. Dadurch sind in einfacher Weise hohe Belastungen vermieden.6 shows the upper punching tool in the position in which the third pair of incisions is only partially cut. The incision of the first and the second pair of incisions is, however, completely finished. 7 shows the upper punching tool 21 in the position in which the third pair of cuts has been made completely in the overlapping band ends. The cutting process on the first, second and third pair of cuts is thus started in a simple manner one after the other and the cutting processes are also carried out one after the other completed. As a result, high loads are avoided in a simple manner.

Um das aufeinanderfolgende Einschneiden und das aufeinanderfolgende Beenden der einzelnen Einschnittvorgänge zu erzielen, hat die Arbeitsfläche 22 des oberen Stanzwerkzeuges 21 eine im wesentlichen abrollende Bewegung auf der Arbeitsfläche 29 des unteren Stanzwerkzeuges 2o durchgeführt. Die dem unteren Stanzwerkzeug 20 zugekehrte Arbeitsfläche 22 des oberen Stanzwerkzeuges 21 ist dabei in Anpassung an seine abrollende Bewegung bogenförmige ausgebildet. Die mit dem unteren Stanzwerkzeug 20 zusammenwirkende Arbeitsfläche 22 des oberen Stanzwerkzeuges 21 ist in Umfangsrichtung zur Spanneinrichtung 14 hin etwas verlängert und weist ein an sich bekanntes Kerbmesser 36 zum Abtrennen des überschüssigen, zur Vorratsrolle führenden Umreifungsbandes auf. Das obere Stanzwerkzeug 21 weist somit in einfacher Weise zugleich auch ein Kerbmesser 36 auf, um bei der Stanzbewegung zugleich das überschüssige Umreifungsband von der Umreifung abtrennt. Durch die abrollende Bewegung des oberen Stanzwerkzeuges kann dabei, wie insbesondere auf Fig. 8 ersichtlich, der Abkerbvorgang zeitlich nach dem vollständigen Einbringen der Einschnittpaare durchgeführt werden. Der Abkerbvorgang ist somit zeitlich vor dem Einstanzen der Einschnittpaare getrennt, so daß die Einschnittpaare jeweils unabhängig vom Abkerben mit der gewünschten gleichen Einschnittlänge und Tiefe gefertigt werden können, was sich positiv auf die Verschlußfestigkeit auswirkt. Nach dem vollständigen Einstanzen der drei Einschnittpaare in die sich überlappenden Bandenden 13 und dem nachfolgenden Abkerben des überschüssigen Umreifungsbandes wird durch entsprechende Betätigung des Betätigungshebels 26 das obere Stanzwerkzeug 21 in die Grundstellung zurückgeführt, die in der Fig. 2 näher dargestellt ist.In order to achieve the successive incision and the consecutive termination of the individual incision processes, the working surface 22 of the upper punch 21 has performed an essentially rolling movement on the working surface 29 of the lower punch 2o. The working surface 22 of the upper punching tool 21 facing the lower punching tool 20 is designed to be arcuate in adaptation to its rolling movement. The working surface 22 of the upper punch 21, which cooperates with the lower punch 20, is somewhat extended in the circumferential direction towards the tensioning device 14 and has a notch knife 36 known per se for severing the excess strapping band leading to the supply roll. The upper punch 21 thus also has a notch knife 36 in a simple manner, in order to simultaneously cut off the excess strapping from the strapping during the punching movement. As a result of the rolling movement of the upper punching tool, as can be seen particularly in FIG. 8, the notching process can be carried out in time after the pairs of cuts have been completely inserted. The notching process is thus separated before the punching of the incision pairs, so that the incision pairs can be made with the same incision length and depth regardless of the notching, which has a positive effect on the closure strength. After the three pairs of cuts have been completely punched into the overlapping strap ends 13 and the subsequent notching of the excess strapping strap, the upper punch 21 is returned to the basic position by corresponding actuation of the actuating lever 26, which is shown in more detail in FIG. 2.

Wie insbesondere aus der Fig. 1 ersichtlich, kann der den zylindrischen seitlichen Ansatz 27 des oberen Stanzwerkzeuges 21 aufnehmende Gleitstein 32 an seinem zum unteren Stanzwerkzeug 20 gerichteten Ende zwei die zwischen den beiden Stanzwerkzeugen 20,21 angeordneten Umreifungsbandende 13 im Randbereich untergreifende Aushebeansätze 35 aufweisen. Dadurch wird in einfacher Weise erreicht, daß beim Rückführen des Betätigungshebels 26 zwangsläufig das obere Stanzwerkzeug 21 in die Grundstellung zurückgeführt wird und bei dieser Rückführung zwangsläufig die sich überlappenden Bandenden 13 von dem unteren Stanzwerkzeug 2o abgehoben werden.As can be seen in particular from FIG. 1, the sliding block 32 receiving the cylindrical side extension 27 of the upper punch 21 can have at its end facing the lower punch 20 two strapping ends 13 arranged between the two punching tools 20, 21 in the edge area and under the lifting portions 35. It is thereby achieved in a simple manner that when the actuating lever 26 is returned, the upper punch 21 is inevitably returned to the basic position and the overlapping tape ends 13 are inevitably lifted off the lower punch 20 during this return.

Wie bereits erwähnt, ist die dargestellte Ausführung lediglich eine beispielsweise Verwirklichung der Erfindung und diese nicht darauf beschränkt. Vielmehr sind noch mancherlei andere Ausführungen und Abänderungen möglich. So könnte das einstückig dargestellte obere Stanzwerkzeug auch zweiteilig ausgebildet sein, wobei das eigentliche Stanzwerkzeug aus einer flachen Platte besteht und an einem Träger befestigt ist.As already mentioned, the embodiment shown is merely an example of realizing the invention and it is not restricted thereto. Rather, various other designs and modifications are possible. For example, the upper punching tool shown in one piece could also be formed in two parts, the actual punching tool consisting of a flat plate and being fastened to a carrier.

  2. A strapping device according to claim 1,
    characterised in that the upper cutting tool (21) comprises at its end remote from the curved working surface (22), an opening (23) for the purpose of receiving in a form-locking manner an eccentric (25) driven by a drive shaft (24) and is guided at its end comprising the curved working surface (22) with a lateral projection (27) in a groove (28) which extends perpendicular to the working surface (29) of the lower cutting tool (20), wherein the pivot axis (30) formed by the lateral projection (27) is disposed approximately in the plane of the curved working surface (22) of the upper cutting tool (21).
  3. A strapping device according to claim 2,
    characterised in that the shaft (24) comprising the drive eccentric (25) for the upper cutting tool (21) is disposed perpendicular over the longitudinal centre of the lower cutting tool (20) and the groove (28) guiding the lateral projection (27) of the upper cutting tool (21) likewise extends perpendicular in the longitudinal centre of the lower cutting tool (20).
  4. A strapping device according to one of claims 2 or 3,
    characterised in that the lateral projection (27) of the upper cutting tool (21) engages a round cross-sectional surface and engages in a bore (31) of a sliding block (32) guided in the groove (28).
  5. A strapping device according to claim 4,
    characterised in that the sliding block (32) receiving the cylindrical lateral projection (27) of the upper cutting tool (21) comprises at its end directed towards the lower cutting tool (20) at least one lifting projection (35) which is known per se and engages below the hooping strip ends (13) disposed between the two cutting tools (20, 21) in the edge region.
  6. A strapping device according to claims 1 to 5
    characterised in that the rotational movement of the drive shaft (24) with the eccentric (25) engaging in a form-locking manner in an opening (23) of the upper cutting tool (21) is delimited by a hand lever (26).
  7. A strapping device according to one of claims 1 to 6,
    characterised in that the curved working surface (22) of the upper cutting tool (21), which cooperates with the lower cutting tool (20), is slightly extended in the hooping direction at its end which finally becomes effectively connected to the lower cutting tool (20) by virtue of the roll-off movement and comprises in the extended region a cutting knife (36) known per se for the purpose of separating the excess hooping strip leading to a supply roll.
