Definitions
- the invention has for its object to accomplish this with less effort.
- the solution according to the invention is that the tensioning element acting on the strap is set up to slip on the strap to be tensioned when a predetermined strap tension is reached.
- slip clutches are known to generally not allow the slip force limit to be set precisely and constantly if the number the work cycles are large and the size of the coupling must be kept small, measured by the force to be transmitted. This is due to the fact that wear must be expected with slip clutches, which changes the interacting clutch surfaces so that a predictable function is not guaranteed in the long run.
- the tensioning element is expediently formed by a tensioning roller.
- the limit tension at which the tension member slips is determined by the fact that the distance between the tension member and an abutment supporting the belt on the side facing away from the tension member is adjustable. However, it should also not be excluded that the force with which the band is pressed against the tensioning element by the abutment can instead be adjusted.
- the abutment is expediently a role, especially when the tensioning member is also a role.
- the surface of the tensioning member can indeed be smooth, the friction force acting between this surface and that of the belt being determined by the contact pressure; however, since the random surface condition of the strip can lead to deviating results, the design of the tensioning element with protrusions penetrating into the strip surface is preferred.
- these projections cause a deformation of the band material, which can be different depending on the type of the projections. If the protrusions are sharp, the strip may be scraped or even machined. This solution is generally preferred because it is the most easily reproducible result as long as the tape material remains the same. However, it is also possible that Form protrusions bluntly, whereby the plastic material displacement (in addition to any material abrasion) can be decisive.
- the tool 1 shows a tool 1 for tensioning a cable tie 2 around a wire harness 3.
- the tool has a tensioning roller 4 provided with a drive (not shown) and a counter roller 5, between which the end 6 of the cable strap 2 to be tensioned is passed.
- the tool has a blade 7, with which the protruding and subjected to the action of the tension roller 4 band end 6 is cut after tensioning.
- the tool 1 can have a substantially different shape than that shown in FIG. 1.
- it can be a so-called automatic tool, which has guides around the wire harness 3 for automatic wrapping of the wire harness through the band 2.
- the band 2 is preferably a plastic band, for example made of polyamide, the thickness of which is typically between 1 and 2 mm.
- an adjusting screw 8 or the like is provided in order to be able to adjust the distance or the contact pressure between the tensioning roller 4 and the counter roller 5 of the strip thickness used in each case and to be able to adjust the strip tension.
- the tensioning roller 4 is provided on the circumference with axially parallel, rib-like projections or teeth 9, the radial height of which above the other roller circumference is substantially less than the thickness of the band section 6 interacting with the tensioning roller 4.
- the projections 9 cannot slide over the surface of the belt, but rather penetrate into it with preferably plastic deformation, the penetration depth being determined by the setting of the distance or the contact pressure between the rollers 4 and 5 .
- the tracks 10 remaining on the tape do not impair its strength because they lie in the tape section 6 to be cut.
- the cross-sectional area of the band material which is acted upon by the projections 9, and thus the force which can be transmitted to the band 6 by the projections, depends on the depth of engagement of the projections, and that therefore the band tension at which the band tension is adjustable can also be adjusted the tensioning process is ended by the tensioning roller 4 slipping relative to the belt section 6.
- the arrangement is extremely simple and effective and allows a considerable reduction in the effort compared to conventional belt tension limiters.
- the device is also not threatened by wear, because the tensioning roller 4 can easily be manufactured from a material which is so hard in comparison with the strip material that it is practically not exposed to wear.

Description
Bei Vorrichtungen zum Binden von Kabelbäumen oder anderen Gegenständen mittels eines flexiblen Bandes, das in der gespannten Bindestellung mittels einer Verschlußeinrichtung zu sichern ist, spielt die Begrenzung der Bandspannung auf einen vorherbestimmten Wert eine bedeutende Rolle, da durch zu hohe Bandspannung der zu bindende Gegenstand oder das Band selbst beschädigt werden könnte. Im Stand der Technik werden dafür unterschiedliche Formen sogenannter Lastwaagen verwendet. Dabei ist in den Kraftübertragungsweg eine Kupplung eingeschaltet, die die Spannkraft über eine schiefe Ebene überträgt, die sich dann löst, wenn die durch die schiefe Ebene quer zum normalen Kraftübertragungsweg wirkende Kraftkomponente eine bestimmte Kraftschwelle übersteigt, die durch eine einstellbare Federkraft bestimmt wird. Die Ausführung dieses Prinzips kann sehr unterschiedlich sein (DE-OS 25 10 575, GB-OS 83 25 128, WO 82/02867, DE-OS 19 07 306), ist aber in jedem Fall sehr aufwendig. Jedoch wurde es bislang für unabdingbar gehalten, weil die Grenzspannung auch nach vielen Arbeitsspielen noch zuverlässig einstellbar sein muß.In devices for tying cable harnesses or other objects by means of a flexible band, which is to be secured in the tensioned binding position by means of a locking device, the limitation of the band tension to a predetermined value plays an important role, since the object to be tied by the band tension being too high Tape itself could be damaged. In the prior art, different forms of so-called load scales are used for this. In this case, a clutch is switched on in the power transmission path, which transmits the clamping force over an inclined plane, which is released when the force component acting through the inclined plane transversely to the normal force transmission path exceeds a certain force threshold, which is determined by an adjustable spring force. The execution of this principle can be very different (DE-OS 25 10 575, GB-OS 83 25 128, WO 82/02867, DE-OS 19 07 306), but is very expensive in any case. However, it has so far been considered essential because the limit voltage must still be reliably adjustable even after many work cycles.
Der Erfindung liegt die Aufgabe zugrunde, dies mit geringerem Aufwand zu bewerkstelligen.The invention has for its object to accomplish this with less effort.
Die erfindungsgemäße Lösung besteht darin, daß das auf das Band einwirkende Spannorgan zum Durchrutschen an dem zu spannenden Band beim Erreichen einer vorbestimmten Bandspannung eingerichtet ist.The solution according to the invention is that the tensioning element acting on the strap is set up to slip on the strap to be tensioned when a predetermined strap tension is reached.
Diese Lösung ist insofern erstaunlich, als sie darauf hinausläuft, eine Rutschkupplung zwischen dem Spannorgan und dem zu spannenden Band zu bilden, wobei aber Rutschkupplungen dafür bekannt sind, daß sie in der Regel eine genaue und konstant bleibende Einstellung der Rutschkraftgrenze nicht gestatten, wenn die Zahl der Arbeitsspiele groß ist und die Baugröße der Kupplung klein gehalten werden muß, gemessen an der zu übertragenden Kraft. Das liegt daran, daß bei Rutschkupplungen mit Verschleiß gerechnet werden muß, der die zusammenwirkenden Kupplungsflächen so verändert, daß eine berechenbare Funktion nicht auf Dauer gewährleistet ist.This solution is surprising in that it boils down to forming a slip clutch between the tensioning element and the band to be tensioned, but slip clutches are known to generally not allow the slip force limit to be set precisely and constantly if the number the work cycles are large and the size of the coupling must be kept small, measured by the force to be transmitted. This is due to the fact that wear must be expected with slip clutches, which changes the interacting clutch surfaces so that a predictable function is not guaranteed in the long run.
Ferner werden aus tribologischer Sicht hohe Anforderungen an die Eigenschaften der die Rutschkupplung bildenden Werkstoffe gestellt. Hingegen können solche Werkstoffe, aus denen typischerweise elastische Bänder zum Binden von Kabelbäumen bestehen, solche Anforderungen an die Materialeigenschaften bei weitem nicht erfüllen, da sie nach gänzlich anderen Gesichtspunkten gewählt sind. Um so überraschender ist es, daß die bekannten Nachteile von Rutschkupplungen in dem erfindungsgemäßen Zusammenhang nicht auftreten. Das hat zwei Gründe. Zum einen wird der Kupplung für jedes Arbeitsspiel in Gestalt eines neuen Bandes ein neuer Reibpartner zur Verfügung gestellt, dessen Eigenschaften noch nicht durch vorangegangene Arbeitsspiele verändert sind. Zum anderen tritt zwar beim Durchrutschen der Kupplung an dem durch das Band gebildeten Reibpartner eine wesentliche, verschleißbedingte Änderung ein, weil infolge des Verschleißes die Reibpartner der Kupplung mit nur noch verringerter Kraft zusammengepreßt sind. Dies wirkt sich aber nicht negativ aus, weil leicht dafür gesorgt werden kann, daß die Verschlußeinrichtung für das Band unverzüglich geschlossen wird, sobald die vorbestimmte Bandspannung erreicht ist. Dies ist ohne weiteres gewährleistet, wenn ein Band mit selbstrastender Verschlußeinrichtung (EP-A 35367, Fig. 2) verwendet wird, bei dem also die Verschlußstellung des Bandes durch die höchste während des Spannvorgangs erreichte Bandspannung bestimmt wird, während ein nachfolgendes Absenken dieser Spannung ohne Einfluß bleibt. Ferner ist es vorteilhaft, wenn im Zusammenhang der Erfindung Bänder aus Kunststoff oder wenigstens aus einem im Vergleich mit dem Material des anderen Kupplungsteils weichen Werkstoff verwendet wird, der diesem anderen Teil der Kupplung keinen wesentlichen Verschleiß zufügt.Furthermore, from a tribological point of view, high demands are made on the properties of the materials forming the slip clutch. On the other hand, such materials, which typically consist of elastic bands for binding cable harnesses, cannot meet such requirements for the material properties by far, since they are chosen from completely different points of view. It is all the more surprising that the known disadvantages of slip clutches do not occur in the context according to the invention. There are two reasons for this. On the one hand, the clutch is provided with a new friction partner for each work cycle in the form of a new belt, the properties of which have not yet been changed by previous work cycles. On the other hand, when the clutch slips on the friction partner formed by the belt, a significant change due to wear occurs because, due to wear, the friction partners of the clutch are compressed with only a reduced force. This does not have a negative effect, however, because it can easily be ensured that the closure device for the band is closed immediately as soon as the predetermined band tension is reached. This is easily ensured if a belt with a self-locking closure device (EP-A 35367, Fig. 2) is used, in which the closure position of the belt is determined by the highest belt tension reached during the tensioning process, while a subsequent lowering of this tension without Influence remains. It is also advantageous if, in the context of the invention, strips made of plastic or at least of a material which is soft in comparison with the material of the other coupling part and which do not cause any significant wear to this other part of the coupling are used.
Zweckmäßigerweise wird das Spannorgan von einer Spannrolle gebildet. Die Grenzspannung, bei welcher das Spannorgan durchrutscht, wird dadurch bestimmt, daß der Abstand zwischen dem Spannorgan und einem das Band auf der dem Spannorgan abgewandten Seite abstützenden Widerlager einstellbar ist. Jedoch soll auch nicht ausgeschlossen werden, daß stattdessen die Kraft einstellbar ist, mit der das Band durch das Widerlager gegen das Spannorgan gepreßt wird. Das Widerlager ist zweckmäßigerweise eine Rolle, insbesondere dann, wenn auch das Spannorgan eine Rolle ist.The tensioning element is expediently formed by a tensioning roller. The limit tension at which the tension member slips is determined by the fact that the distance between the tension member and an abutment supporting the belt on the side facing away from the tension member is adjustable. However, it should also not be excluded that the force with which the band is pressed against the tensioning element by the abutment can instead be adjusted. The abutment is expediently a role, especially when the tensioning member is also a role.
Zwar kann die Oberfläche des Spannorgans glatt ausgebildet sein, wobei die zwischen dieser Oberfläche und derjenigen des Bands wirkende Reibkraft durch die Anpreßkraft bestimmt wird; da aber dabei der zufällige Oberflächenzustand des Bands zu abweichenden Ergebnissen führen kann, wird die Ausbildung des Spannorgans mit in die Bandoberfläche eindringenden Vorsprüngen bevorzugt. Diese Vorsprünge bewirken beim Durchrutschen des Spannorgans gegenüber dem Band eine Verformung des Bandmaterials, die je nach Art der Vorsprünge unterschiedlicher Art sein kann. Wenn die Vorsprünge scharf sind, kann sich eine schabende oder gar spanhebende Verformung des Bands ergeben. Diese Lösung wird im allgemeinen bevorzugt, weil sich dabei am leichtesten reproduzierbare Resultate ergeben, solange das Bandmaterial gleich bleibt. Jedoch ist es auch möglich, die Vorsprünge stumpf auszubilden, wobei die plastische Materialverdrängung (neben etwaigem Materialabrieb) maßgeblich sein kann.The surface of the tensioning member can indeed be smooth, the friction force acting between this surface and that of the belt being determined by the contact pressure; however, since the random surface condition of the strip can lead to deviating results, the design of the tensioning element with protrusions penetrating into the strip surface is preferred. When the tensioning member slips against the band, these projections cause a deformation of the band material, which can be different depending on the type of the projections. If the protrusions are sharp, the strip may be scraped or even machined. This solution is generally preferred because it is the most easily reproducible result as long as the tape material remains the same. However, it is also possible that Form protrusions bluntly, whereby the plastic material displacement (in addition to any material abrasion) can be decisive.
Da viele Kunststoffbänder, die für die erfindungsgemäßen Zwecke verwendbar sind, einseitig gezahnt sind, erscheint es auf den ersten Blick naheliegend, das Spannorgan auf die gezahnte Seite des Bandes einwirken zu lassen, um den durch die Zahnung möglichen, formschlüssigen Eingriff für den Spannvorgang zu nutzen. Dies soll im Rahmen der Erfindung zwar nicht ausgeschlossen werden. Vorteilhafter ist aber in der Regel das Einwirken des Spannorgans auf eine ungezahnte Fläche des Bandes, weil sich gezeigt hat, daß dann leichter reproduzierbare Ergebnisse erzielbar sind.Since many plastic straps that can be used for the purposes of the invention are serrated on one side, it seems obvious at first glance to allow the tensioning element to act on the serrated side of the strap in order to use the positive engagement possible by the serration for the tensioning process . This should not be excluded within the scope of the invention. However, the action of the tensioning element on an toothless surface of the belt is generally more advantageous because it has been shown that results which are more easily reproducible can then be achieved.
Die Erfindung wird im folgenden näher unter Bezugnahme auf die Zeichnung erläutert, die in schematischer Darstellung ein vorteilhaftes Ausführungsbeispiel veranschaulicht. Darin zeigen:
- Fig. 1 die Teildarstellung eines Werkzeugs mit einem zu spannenden Kabelband,
- Fig. 2 eine Spannrolle im Eingriff mit einem zu spannenden Kabelband ohne Relativbewegung dieser beiden Teile zueinander und
- Fig. 3 eine der Fig. 2 entsprechende Darstellung beim Durchrutschen der Spannrolle.
- 1 is a partial representation of a tool with a cable band to be tensioned,
- Fig. 2 is a tension roller in engagement with a cable strap to be tensioned without relative movement of these two parts to each other and
- Fig. 3 is a representation corresponding to FIG. 2 when the tensioning roller slips.
Fig. 1 zeigt ein Werkzeug 1 zum Spannen eines Kabelbands 2 um einen Kabelbaum 3. Zu diesem Zweck besitzt das Werkzeug eine mit einem nicht gezeigten Antrieb versehene Spannrolle 4 und eine Gegenrolle 5, zwischen denen das zu spannende Ende 6 des Kabelbands 2 hindurchgeführt ist. Ferner besitzt das Werkzeug eine Klinge 7, mit der das überstehende und der Einwirkung der Spannrolle 4 unterworfene Bandende 6 nach dem Spannen abgeschnitten wird. Selbstverständlich kann das Werkzeug 1 eine wesentlich andere Gestalt als in Fig. 1 gezeigt annehmen.1 shows a tool 1 for tensioning a cable tie 2 around a wire harness 3. For this purpose, the tool has a tensioning roller 4 provided with a drive (not shown) and a
Insbesondere kann es sich um ein sogenanntes automatisches Werkzeug handeln, das den Kabelbaum 3 umgreifende Führungen für eine automatische Umschlingung des Kabelbaums durch das Band 2 aufweist.In particular, it can be a so-called automatic tool, which has guides around the wire harness 3 for automatic wrapping of the wire harness through the band 2.
Bei dem Band 2 handelt es sich vorzugsweise um ein Kunststoffband, beispielsweise aus Polyamid, dessen Dicke typischerweise zwischen 1 und 2 mm liegt. Um den Abstand oder die Anpreßkraft zwischen der Spannrolle 4 und der Gegenrolle 5 der jeweils verwendeten Banddicke anpassen und die Bandspannung einstellen zu können, ist eine Stellschraube 8 oder dergleichen vorgesehen.The band 2 is preferably a plastic band, for example made of polyamide, the thickness of which is typically between 1 and 2 mm. In order to be able to adjust the distance or the contact pressure between the tensioning roller 4 and the
Die Spannrolle 4 ist, wie in Fig. 2 und 3 gezeigt, am Umfang mit achsparallel verlaufenden, rippenartigen Vorsprüngen oder Zähnen 9 versehen, deren radiale Höhe über dem sonstigen Rollenumfang wesentlich geringer als die Dicke des mit der Spannrolle 4 zusammenwirkenden Bandabschnitts 6 ist. Andererseits ist sie so groß, daß die Vorsprünge 9 nicht über die Oberfläche des Bands hinweggleiten können, sondern unter vorzugsweise plastischer Verformung der Bandoberfläche in diese eindringen, wobei die Eindringtiefe durch die Einstellung des Abstands bzw. der Anpreßkraft zwischen den Rollen 4 und 5 bestimmt ist. Die am Band verbleibenden Spuren 10 beeinträchtigen dessen Festigkeit nicht, weil sie in dem abzuschneidenden Bandabschnitt 6 liegen.As shown in FIGS. 2 and 3, the tensioning roller 4 is provided on the circumference with axially parallel, rib-like projections or teeth 9, the radial height of which above the other roller circumference is substantially less than the thickness of the
Der Antrieb der Spannrolle 4 in Pfeilrichtung führt dazu, daß das Band in der Spannrichtung bewegt wird. Dabei steigt dessen Spannung, bis eine Grenze erreicht ist, bei welcher die Festigkeit des von dem Eingriff der Vorsprünge 9 erfaßten Bandmaterials gegenüber der von den Vorsprüngen 9 darauf ausgeübten Kraft nicht mehr standzuhalten vermag. In diesem, in Fig. 3 dargestellten Zustand bleibt das Band 6 gegenüber der sich weiter drehenden Spannrolle 4 stehen, wobei die Vorsprünge 9 der Spannrolle die Oberfläche des Bands entsprechend deformieren. Sind sie - wie gezeigt - verhältnismäßig scharf ausgebildet, so führt dies zum Abschälen von Spänen 11 und der Bildung einer Auskehlung 12 in der Bandoberfläche. Da demzufolge die zwischen der Spannrolle 4 und der Gegenrolle 5 wirksame Banddicke reduziert wird, wird auch die übertragbare Bandspannung reduziert. Dies schadet aber nicht, weil bis dahin der Bandverschluß im Kopf 13 des Bands 2 geschlossen ist, beispielsweise durch Verwendung eines selbstrastenden Verschlusses.The drive of the tension roller 4 in the direction of the arrow causes the belt to be moved in the tension direction. In the process, its tension increases until a limit is reached at which the strength of the strip material gripped by the engagement of the projections 9 can no longer withstand the force exerted thereon by the projections 9. In this state, shown in FIG. 3, the
Man erkennt, daß die Querschnittsfläche des Bandmaterials, die von den Vorsprüngen 9 beaufschlagt ist, und damit die durch die Vorsprünge auf das Band 6 übertragbare Kraft von der Eingriffstiefe der Vorsprünge abhängt, und daß daher durch die Eingriffstiefe auch diejenige Bandspannung einstellbar ist, bei der der Spannvorgang durch Durchrutschen der Spannrolle 4 gegenüber dem Bandabschnitt 6 beendet wird. Die Anordnung ist äußerst einfach und wirkungsvoll und gestattet eine beträchtliche Verringerung des Aufwands gegenüber herkömmlichen Bandspannungsbegrenzern. Die Vorrichtung ist auch nicht verschleißbedroht, weil die Spannrolle 4 leicht aus einem Werkstoff hergestellt werden kann, der im Vergleich mit dem Bandmaterial so hart ist, daß er praktisch keinem Verschleiß ausgesetzt ist.It can be seen that the cross-sectional area of the band material, which is acted upon by the projections 9, and thus the force which can be transmitted to the
