Abstract

1. Closure-less secured metal band for packages, the overlapping ends (10, 11) of which are provided with cooperating pairs of angled notches, which divide the band in the longitudinal direction into sectional lengths in the web portion, which bend out from the plane of the band in opposite directions, form slits (16) and are arranged in sequence in the longitudinal direction of the band and are spaced from each other, whereby under the action of the circumferential tension in the band, the corner regions (17) of the angled notches mutually interengage and become held in the finally engaged positions at the ends of the slits (16) and the thus-completed band is secured against coming open, characterised in that the angled notches known per se are so formed with their portions pressed out of the plane of the band in opposite directions to the slits (16), that the interengaging corner regions (17) of the locking elements (15) are curved towards the slits (16) at both ends (10, 11) of the band.

Description

Die Erfindung betrifft eine hülsenlos verschlossene Metallbandumreifung mit Verschlußsicherung für die Umreifung von Packstücken. Der Verschluß ist mit einer Verschließvorrichtung, wie z. B. mit einem Spann- und Verschlißgerät, her gestellt und er ist in den sich überlappenden Bandenden mit paarweise zusammengehörenden Verschlußelementen versehen, die in Längsausdehnung des Bandes winkelförmig eingestanzt sind, wodurch das Band auf der Einschnittlänge in Stege geteilt wird, die gegeneinander aus der Ebene des Bundes herausgedrückt sind und schlitzförmige Öffnungen bilden. Durch Freiwerden der vorher eingebrachten Bandspannung mittels besagter Spann- und Verschlußvorrichtung in der so gebildeten Umreifung bewirken die Rücksellkräfte im Überlappungsbereich des Verschlusses über den Verhakweg das Hintergreifen der Eckenbereiche an den winkelförmigen Einschnitten und damit die Verschlußbildung.The invention relates to a sleeveless closed metal strapping with locking device for strapping packages. The closure is with a closing device, such as. B. with a tensioning and capping device, and it is provided in the overlapping band ends with paired closure elements that are angularly punched in the longitudinal extent of the band, whereby the band is divided into the incision length in webs, which are mutually out of the plane of the federal government are pressed out and form slit-shaped openings. By releasing the previously introduced strap tension by means of said tensioning and closure device in the strapping thus formed, the resetting forces in the overlap region of the closure over the interlocking path cause the corner regions to engage behind the angular incisions and with it the formation of closures.

Die Sicherung der hülsenlos verschlossenen Packstückumreifungen gegen Wiederöffnen ist notwendig z. B. bei schrumpfenden Packstücken, wie Kisten, Paletten etc., bei denen durch Schrumpfen die Umreifung locker wird. Ein nicht gesicherter Verschluß wäre dann schon durch geringe Kräfte in der der Umreifungsspannung entgegenwirkenden Richtung lösbar.It is necessary to secure the package-tight strapping against reopening, e.g. B. with shrinking packages, such as boxes, pallets, etc., in which the strapping is loosened by shrinking. An unsecured closure would then be detachable even by small forces in the direction counteracting the strapping tension.

Es sind Verschlußsicherungen bekannt, die gemäß DE-PS 12 55 568 ein Wiederöffnen dadurch verhindern, daß der Stanzvorgang für die Verschlußelemente so vorgenommen wird, daß nach dem Stanzvorgang für die eigentliche Verschlußbildung nach dem Verhaken eine zusätzliche, sperrende Verschlußeinstanzung vorgenommen wird. Der Vorrichtungsaufwand hierfür ist vergleichsweise groß und ein zusätzlicher Arbeitsgang zum Einbringen der zusätzlichen Verschlußsicherung notwendig.Closure locks are known which, according to DE-PS 12 55 568, prevent reopening in that the punching process for the closure elements is carried out in such a way that, after the punching process for the actual closure formation after hooking, an additional, blocking closure punching is carried out. The outlay on devices for this is comparatively large and an additional work step is necessary to introduce the additional locking device.

Ferner sind Verschlußsicherungen für "hülsenlos"-Verschlüsse bekannt, wobei die Seitenstege nach dem Einstanzen nach innen zur Bandmitte hin gedrückt und verformt werden, so daß die überlappenden Eckenbereiche gegen Wiederöffan verriegelt sind. Diese Art der Yerschlußscherung ist nur dann technisch sinnvoll einzusetzen, wenn der Einstanzvorgang über Zangenbewegungen bewerkstelligt wird, wobei die einschwenkenden Zangenbacken zusätzlich zu der Funktion Verschlußeinschneiden die so entstehenden Seitenstege zur Bandmitte eindrücken. Der Vorrichtungsaufwand ist auch hier groß und die Verformungskräfte bei dicken und hochfesten Bändern verhindern oft eine ausreichende Verformung einer solchen Verschluß- .sicherung.Furthermore, locking devices for "sleeve-free" closures are known, the side webs being pressed inwards towards the middle of the band and deformed after being punched in, so that the overlapping corner regions are locked against reopening. This type of closing shear is only technically useful if the punching process is carried out by means of pliers movements, the pivoting pliers jaws pressing in on the function of cutting the closure and pressing the side webs thus created towards the center of the band. The outlay on the device is also great here and the deformation forces in the case of thick and high-strength tapes often prevent such a closure lock from being sufficiently deformed.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen gegen Wiederöffnen sicheren und in der Bauart einfachen Verschluß zu schaffen, der gleichzeitig mit dem Stanzvorgang die verschlußsichernden Elemente mit einbringt und für jede Stanzvorrichtung universell mit geringem apparativem Aufwand für die Sicherung einsetzbar ist.The present invention has for its object to provide a secure against reopening and simple in design closure, which brings the locking elements with the punching process at the same time and can be used universally for each punching device with little equipment for securing.

Diese Aufgabevird dadurch gelöst, daß die an sich bekannten winkelförmigen Einschnitte mit ihren dadurch gebildeten, aus der Bandebene gegenläufig zu Schlitzen herausgedrückten Stegteile so ausgebildet sind, daß die sich hintergreifenden Eckenbereiche des Verschlusses in beiden Bandenden zur Schlitzöffnung hin gebogen sind. Besonders einfach ist dies durch Verbiegen der Eckenbereiche am mittleren Steg zu erreichen.This object is achieved in that the known angular incisions with their thus formed web parts, which are pressed out of the band plane in the opposite direction to slots, are designed in such a way that the corner regions of the closure which engage behind one another are bent towards the slot opening in both ends of the band. This is particularly easy to achieve by bending the corner areas on the central web.

Der Vorteil der Erfindung besteht darin, daß beim Zusammenziehen des Verschlusses die sich verhak enden gebogenen Eckenbereiche sich übereinanderschieben und dabei zurückfedern und sich breiten. Sie bleiben unterstarkem, federnden Druck verhakt und gegeneinander verspannt.The advantage of the invention is that when the closure is pulled together, the interlocking curved corner regions slide over one another and spring back and widen. They remain under strong, springy pressure and are braced against each other.

Wenn nun z. B. bei schrumpfenden Packstücken das Band locker wird, so sorgt der federnde Druck in den Eckenbereichen für soviel Reibung, daß sich die verhaktenden Eckbereiche nicht mehr voneinander lösen.If now z. B. with shrinking packages, the tape is loose, the resilient pressure in the corner areas ensures so much friction that the hooked corner areas can no longer separate.

Diese Eckbereiche sind aber nicht nur durch den federnden Druck und die Reibung gesichert. Die schräg gebogenen Eckbereiche werden beim Zusammenziehen des Verschlusses auch plastisch etwas gerader gebogen. Durch diese plastische Verbiegung weitet sich das Material geringfügig um etwa 1/10 mm. Durch diese zwar geringe Weitung sind die Teile auch formschlüssig gegeneinander verhakt.These corner areas are not only secured by the resilient pressure and friction. The obliquely curved corner areas are also plastically bent somewhat straighter when the lock is pulled together. Due to this plastic bending, the material widens slightly by about 1/10 mm. Because of this slight expansion, the parts are also positively hooked against one another.

Es lassen sich die für die Verschlußsicherung notwendigen Verbiegungen der Eckenbereiche leicht durch eine Abschrägung der Schneidkanten der Stanzmesser herstellen.The bends in the corner areas necessary for securing the closure can easily be produced by chamfering the cutting edges of the punching knives.

Als weiterer Vorteil hat sich herausgestellt, daß durch die Abschrägung der Messerkanten die Schnittkraft beim Stanzen günstiger wird, und die Stanzwerkzeuge länger halten. Eine weitere Verbesserung wird dadurch erreicht, daß auch der am Seitensteg sich befindende komplementäre Eckenbereich in gleicher Weise zur Schlitzöffnung hin weggebogen ist.Another advantage has been found to be that the beveling of the knife edges makes the cutting force more favorable when punching, and keep the punching tools longer. A further improvement is achieved in that the complementary corner area located on the side web is bent away in the same way towards the slot opening.

Wird z. B. der Verschluß wider Erwarten nach dem Verhakten gewaltsam zurückgeschoben, so bewirkt die Breitung der zurückgefederten Eckenbereiche eine Überlappung in der Art einer Verriegelung dadurch, daß die Breite des jeweils eingefügten gebreiteten Stegteils größer ist als die zugehörige Öffnung im anderen Bandende. Vorteilhaft ist in diesem Fall, wenn der Bereich der winkelförmigen Einschnittkante, welcher am nächsten zur äußeren Bandkante liegt, etwas schräg aus einer vom Bandinneren zur Bandaussenkante verlaufenden Form gestaltet wird.Is z. B. the closure, contrary to expectations, forcibly pushed back after the hooking, the spreading of the spring-back corner regions causes an overlap in the manner of a lock in that the width of the respectively inserted web part is greater than the associated opening in the other end of the band. In this case, it is advantageous if the area of the angular incision edge, which is closest to the outer band edge, is designed somewhat obliquely from a shape running from the inside of the band to the outer edge of the band.

Die Schrägform ermöglicht eine hintere Anschlagstellung in der auch dann die quer zum Band verlaufenden Einschnittbereiche der Winkeleinschnitte überlappt und verriegelt bleiben.The oblique shape enables a rear stop position in which the incision areas of the angular incisions, which extend transversely to the band, remain overlapped and locked.

Es ist von Vorteil, wenn der Verbiegungswinkel Alpha des Eckenbereiches zwischen 10° und 400 liegt.It is advantageous if the deflection angles Alpha is the corner region between 10 ° and 40 the 0th

An embodiment of the invention is shown in drawings and will be described below.
  • FIG. 1 shows the perspective view of the secured closure with the bent corner regions 17
  • Figure 2
    and
  • 3 shows the schematic cross-sectional representation of a closure incision after stamping (FIG. 2) and after hooking (FIG. 3) with the bent corner regions 17
  • Figure 4
    and
  • FIG. 5 shows the schematic cross-sectional illustration of a closure incision after punching (FIG. 4) and after hooking (FIG. 5) with the complementary corner regions 18 bent
  • FIG. 6 shows the top view of a fastener secured in this way, with the inclined region of the incision region 12 in the overlap of the corner regions 13 running transversely to the band in the pushed-back stop position.

In Figur 1 ist der gestanzte Verschluß kurz vor dem endgültigen Verhaken nach dem Einstanzen dargestellt. Die Eckenbereiche 17 beider Bandenden 10 und 11 der mittleren Stegteile sind zur Schlitzöffnung 16 hingebogen. Ebenso ist in der Darstellung der Verhakvorgang gezeigt, bei dem sich die Eckenbereiche 17 im Bandende 11 mit den komplementären Eckenbereichen des Bandendes 10 gegenseitig hintergreifen.In Figure 1, the punched closure is shown shortly before final hooking after punching. The corner regions 17 of both band ends 10 and 11 of the middle web parts are bent towards the slot opening 16. Likewise, the interlocking process is shown in the illustration, in which the corner regions 17 in the band end 11 engage behind one another with the complementary corner regions of the band end 10.

In Figur 2 ist der Querschnitt eines Verschlußelementes 15 in der Seitenansicht von Figur 1 dargestellt unmittelbar nach dem Stanzen, vor dem Verhaken. Die angebogenen Eckenbereiche 17 haben in beiden Bandenden 10 und 11 noch den gleichen Biegewinkel Alpha.In Figure 2, the cross section of a closure element 15 is shown in the side view of Figure 1 immediately after punching, before snagging. The bent corner regions 17 still have the same bending angle alpha in both band ends 10 and 11.

Im Verlaufe des Verhakweges streckt sich gemäß Figur 3 der Eckenbereich 17 des Bandendes 11 federnd und unter Reibungsdruck gleitend über den komplementären Eckenbereich 18 und erfährt so durch den flacher werdenden Winkel Alpha eine Breitung so daß die Stegbreite 19 größer als die zugehörige Öffnung 14 _ im anderen Bandende wird.3, the corner region 17 of the band end 11 extends resiliently and under frictional pressure, sliding over the complementary corner region 18 and is thus widened by the flattening angle alpha, so that the web width 19 is larger than the associated opening 14 _ in the other Band ends.

In Figur 4 und 5 ist gemäß Anspruch 2 verdeutlicht, daß die komplementären Eckenbereiche 18 an den durch die Schlitzöffnung entstehenden wellenförmigen Stegteile der Bandenden 10 und 11 zur Schlitzöffnung hin verformt sein können mit dem gleichen Effekt der Verschlußsicherung nach dem Verhaken.In FIGS. 4 and 5 it is clarified according to claim 2 that the complementary corner regions 18 on the undulating web parts of the band ends 10 and 11 which arise through the slot opening point towards the slot opening can be deformed with the same effect of locking the lock after snagging.

In vorteilhafter Weise kann gemäß Figur 6 - der Winkeleinschnitt mit seinem Einschnittbereich 12 der der äußeren Bandkante am nächsten liegt, schräg gestaltet werden. Hierdurch ist bewirkt, daß bei evtl. ge- . waltsamer Rückverschiebung durch die Stegweitung in rückwärtiger Stellung eine Anschlagstellung erreicht wird, die auch eine Überlappung der quer verlaufenden Einschnittbereiche 13 der Winkeleinschnitte aufrecht erhält.According to FIG. 6, the angular incision with its incision area 12 that is closest to the outer band edge can advantageously be made oblique. This has the effect that at possibly. violent backward displacement is achieved by the web widening in the rearward position a stop position which also maintains an overlap of the transverse incision areas 13 of the angular incisions.

Der hier beschriebene gesicherte Verschluß gegen Wiederöffnen läßt in der Hintereinanderanordnung der Verschlußelemente verschiedene Kombinationen von Verschlußelementen zu. So ist es möglich, daß nicht sichernde Verschlußbügel als einzelne Verschlußelemente mit einem oder mehreren sichernden Verschlußelementen in der Hintereinanderanordnung kombiniert werden. Ferner ist es möglich, daß alle Verschlußbügel bildende Verschlußelemente durch Abwinkeln der sich verhakenden Eckenbereiche gekennzeichnet ist.The secured closure against reopening described here permits various combinations of closure elements in the arrangement of the closure elements one behind the other. It is thus possible for non-securing closure brackets to be combined as individual closure elements with one or more securing closure elements in the row arrangement. Furthermore, it is possible for all the closure elements forming the closure bracket to be characterized by angling the interlocking corner regions.
