Description

Die Erfindung betrifft ein Werkzeug zum Binden von Gegenständen, insbesondere Kabelbäumen, mit einem Band und einem die Bandenden sichernden Schloß, gemäß dem Oberbegriff des Anspruchs 1. Es ist oftmals erforderlich, die Bandspannung innerhalb vorgegebener Grenzen einzustellen, damit einerseits eine hinreichende Spannung erreicht und andererseits der zu bindende Gegenstand und das Band nicht zu hoch belastet werden. Zu diesem Zweck rüstet man das Werkzeug mit einer Bandspannungsbegrenzungseinrichtung aus. Bei einem ersten Typ von Werkzeugen (EP-B 299 387) ist die Bandspannungsbegrenzungseinrichtung als Lastwaage ausgebildet, in der die in der Bandspanneinrichtung wirkende Kraft mit einer durch eine Feder vorgegebenen Bezugskraft verglichen wird. Übersteigt die in der Bandspanneinrichtung wirkenden Kraft die Bezugskraft, so wird die Verbindung zwischen der Bandspanneinrichtung und einem das Band erfassenden Greifer gelöst. Bei diesem Typ von Werkzeugen ist die Bandspannungsmeßeinrichtung mechanisch in die Bandspannungsbegrenzungseinrichtung integriert. Die Genauigkeit der Bandspannungsbegrenzung ist dadurch stark eingeschränkt. Auch ist es kaum möglich, eine betragsmäßig vorgegebene Bandspannung einzustellen. Bei einem anderen Typ von Werkzeug (EP-B 733 549) wird der Druck in einem pneumatischen Spannantrieb mit einer durch eine einstellbare Feder gebildeten Bezugskraft ebenfalls über eine Art Lastwaage verglichen. Der Spannvorgang wird beendet, sobald eine eingestellte Schwelle erreicht ist. Zwar wird hiermit eine höhere Genauigkeit erreicht als mit den rein mechanisch aufgebauten Bandspannungsbegrenzungseinrichtungen; dennoch ist sie verbesserungswürdig. Auch ist der Bauaufwand vergleichsweise groß. Will man den Betrag der erreichten Spannung ermitteln, so muß zusätzlich ein elektronischer Drucksensor mit Anzeigeeinrichtung vorgesehen werden.The invention relates to a tool for binding objects, especially wire harnesses, with a ribbon and a die Band-locking lock, according to the preamble of the claim 1. It is often necessary to keep the ligament tension within set predetermined limits, on the one hand reached a sufficient tension and on the other hand the to binding object and the tape are not too high. For this purpose, the tool is equipped with a belt tension limiting device out. In a first type of Tools (EP-B 299 387) is the belt tension limiting device designed as a load scale in which the Belt tensioning force with a spring predetermined reference force is compared. Exceeds that force acting in the belt tensioning device is the reference force, so the connection between the tape tensioner and released a gripper gripping the tape. With this type of The belt tension measuring device is mechanically in tools integrated the belt tension limiting device. The precision the band tension limitation is severely limited. It is also hardly possible to have a predetermined amount Adjust the belt tension. Another type of Tool (EP-B 733 549) is the pressure in a pneumatic Tension drive with an adjustable spring Reference force also compared using a kind of load scale. The clamping process is ended as soon as a set one is reached Threshold is reached. This does increase accuracy achieved than with the purely mechanical Belt tension limiters; nevertheless, there is room for improvement. The construction effort is also comparative large. If you want to determine the amount of voltage reached, so must also an electronic pressure sensor with a display device be provided.

Die Nachteile des Standes der Technik werden erfindungsgemäß durch die Mittel des Anspruchs 1 und vorzugsweise durch diejenigen der Unteransprüche vermieden.The disadvantages of the prior art are invented by the means of claim 1 and preferably by those of subclaims avoided.

Demnach ist eine Bandspannungsmeßeinrichtung vorgesehen, die die Beziehung zwischen einer seitlichen Auslenkung des Bands und der dafür erforderlichen Kraft feststellt. Ein wesentlicher Vorteil der Erfindung besteht somit darin, daß die Genauigkeit der Messung nicht durch konstruktive Bedingungen beeinträchtigt wird, die im Hinblick auf die Begrenzung der Bandspannung vorgegeben sind. Ein weiterer wichtiger Vorteil besteht darin, daß die Bandspannung unmittelbar am Band selbst gemessen wird. Wenn die Messung elektronisch stattfindet, fällt auch unmittelbar ein Anzeigesignal an, das die Kontrolle der Einstellung ermöglicht.Accordingly, a belt tension measuring device is provided which the relationship between a lateral deflection of the band and determines the force required for this. An essential one The advantage of the invention is therefore that the accuracy the measurement not by design conditions is affected in terms of limiting the Band tension are specified. Another important advantage is that the tape tension directly on the tape is measured itself. If the measurement takes place electronically, there is also an immediate display signal indicating the Control of the setting enables.

Unter Auslenkung ist zu verstehen, daß das Band zwischen einem Paar von auf einer Seite desselben angeordneten Bandführungen über eine auf seiner anderen Seite befindliche Auslenkungsführung geführt ist, die das Band zu der Seite des Bandführungspaars hin auslenkt. Das Bandführungspaar kann von ohnehin im Werkzeug vorhandenen Führungsteilen gebildet sein, beispielsweise von der Schloßhalterung einerseits und der Bandspanneinrichtung andererseits. Zweckmäßiger ist es jedoch, daß das Bandführungspaar gesondert vorgesehen ist, und zwar in Baueinheit mit der Auslenkungsführung und vorzugsweise auch der Bandspannungsmeßeinrichtung, damit die geometrischen Verhältnisse, die das Ausmaß der Auslenkung bestimmen, durch diese Baueinheit selbst festgelegt werden, unabhängig von sonstigen Bautoleranzen des Werkzeugs. Dabei ist es ein großer Vorteil, daß die Größe der Auslenkung sehr gering sein kann, nämlich vorzugsweise kleiner als ein Fünftel, weiter vorzugsweise kleiner als ein Zehntel und weiter vorzugsweise kleiner als ein Zwanzigstel des Abstands zwischen den Bandführungen. Dies setzt voraus, daß die Auslenkungsführung etwa mittig zwischen den Bandführungen sitzt. Wenn sie wesentlich näher einer Bandführung als der anderen angeordnet ist, sollte die Auslenkung entsprechend kleiner sein. Der Vorteil der kleinen Auslenkung besteht darin, daß das Band nahezu geradlinig hindurchgeschoben werden kann und daher der Bandvorschub davor (d.h., auf der Seite, auf der sich auch die Bandspanneinrichtung befindet) angeordnet sein kann. Dies gestattet es, für den Bandvorschub und die Bandspanneinrichtung dieselben Antriebsorgane zu verwenden.Under deflection is to be understood that the band between one Pair of tape guides arranged on one side thereof via a deflection guide located on its other side which is the tape to the side of the tape guide pair deflects out. The pair of tape guides can anyway guide parts present in the tool must be formed, for example from the lock holder on the one hand and the Belt tensioner on the other hand. However, it is more convenient that the pair of tape guides is provided separately, and although in a unit with the deflection guide and preferably also the belt tension measuring device, so that the geometric Conditions that determine the extent of the deflection, be determined independently by this unit of other construction tolerances of the tool. It is a great advantage that the size of the deflection can be very small can, namely preferably less than a fifth, further preferably less than a tenth, and more preferably less than a twentieth of the distance between the tape guides. This presupposes that the deflection guidance is about sits in the middle between the belt guides. If it is essential is closer to one tape guide than the other the deflection should be correspondingly smaller. The advantage of small deflection is that the tape is almost straight can be pushed through and therefore the tape feed before (i.e. on the side on which the Belt tensioning device is located) can be arranged. This allows it, for the tape feed and the tape tensioning device to use the same drive elements.

Die Bandspannungsmeßeinrichtung ist zweckmäßigerweise so ausgebildet, daß die Kraft an der Umlenkungsführung bei gegebener Größe der Auslenkung gemessen wird. Jedoch kann auch umgekehrt die Größe der Auslenkung bei gegebener Umlenkungskraft gemessen werden, wobei letztere beispielsweise durch eine Feder bestimmt wird. Wenn als Bandspannungsmeßeinrichtung ein elektronisches Meßglied verwendet wird, ist der Meßweg so gering, daß er praktisch vernachlässigbar ist. Außerdem hat dies in Verbindung mit der Ausbildung der Bandspannungsmeßeinrichtung samt Bandführung und Auslenkungsführung als selbständige Baueinheit den Vorteil, daß diese Baueinheit zum Ersatz oder zur Wartung in ihrer Gesamtheit ausgetauscht werden kann. Sie kann auch als optional einsetzbares Element behandelt werden, wobei ein und derselbe Werkzeugtyp sowohl mit als auch ohne Bandspannungsmeßeinrichtung angeboten werden kann oder daß ein ohne Bandspannungsmeßeinrichtung geliefertes Werkzeug leicht mit einer solchen nachgerüstet werden kann.The belt tension measuring device is expediently designed such that that the force on the deflection guide given Size of the deflection is measured. However, the other way around the size of the deflection for a given deflection force are measured, the latter for example by a spring is determined. If as a tape tension measuring device An electronic measuring element is used is the measuring path so small that it is practically negligible. Moreover has this in connection with the formation of the belt tension measuring device including tape guide and deflection guide as an independent unit the advantage that this unit exchanged for replacement or maintenance in its entirety can be. It can also be used as an optional element are treated, with one and the same type of tool both be offered with or without a belt tension measuring device can or that delivered without a tape tension measuring device Tool can be easily retrofitted with one can.

In einer Ausführungsform des Werkzeugs ist die Bandspanneinrichtung mit einer einstellbaren Bandspannungsbegrenzungseinrichtung versehen und ist eine Einrichtung zum Einstellen der Bandspannung vorgesehen, die ihrerseits von der Bandspannungsmeßeinrichtung beeinflußt wird. Die Anordnung kann so getroffen sein, daß bei jedem Abbindevorgang die tatsächlich erreichte und von der Bandspannungsmeßeinrichtung festgestellte Bandspannung mit einem gespeicherten Sollwert verglichen wird. Wenn Abweichungen außerhalb eines bestimmten Toleranzbereichs festgestellt werden, wird die Bandspannungsbegrenzungseinrichtung entsprechend nachgestellt.In one embodiment of the tool, the belt tensioning device is with an adjustable band tension limiting device provided and is a device for adjusting the Belt tension provided, which in turn from the belt tension measuring device being affected. The arrangement can be so be taken that with each setting process the actually reached and determined by the tape tension measuring device Band tension compared with a stored setpoint becomes. If there are deviations outside a certain tolerance range are determined, the band tension limiting device adjusted accordingly.

Bei einer anderen Ausführungsform des erfindungsgemäßen Werkzeugs enthält die Bandspanneinrichtung eine Einrichtung zum Beenden des Spannvorgangs, die unmittelbar von der Bandspannungsmeßeinrichtung gesteuert wird. Beispielsweise kann eine elektrische Schaltkupplung vorgesehen sein, die jeweils dann, wenn die Bandspannungsmeßeinrichtung das Erreichen einer vorbestimmten Bandspannung signalisiert, geöffnet wird. In another embodiment of the tool according to the invention the belt tensioning device contains a device for End the tensioning process immediately from the tape tension measuring device is controlled. For example, a electrical switching clutch can be provided, which when the belt tension measuring device reaches a predetermined Belt tension signals, is opened.

The invention is explained in more detail below with reference to the drawing, which schematically illustrates an embodiment of the invention. Show it:

Das Gehäuse 1 des Werkzeugs enthält in seiner Stirn eine Schloßhalterung 2, in der ein Bandkanal 3 mündet, der das strichpunktiert angedeutete Band 4 zu einem in der Schloßhalterung 2 befindlichen Schloß führt, um zusammen mit diesem in bekannter Weise verarbeitet zu werden. Während der Verarbeitung wird das Band 4 vorgeschoben, um um den zu bindenden Gegenstand geschlungen zu werden. Wenn sein freies Ende in dem in der Schloßhalterung 2 befindlichen Schloß gebunden ist, wird das Band 4 zurückgezogen, um die um das Band geschlungene Schlaufe zu spannen. Für den Vorschub und den Rückzug des Bandes dient eine aus der Antriebsrolle 5 und Gegendruckrollen 6 bestehende Antriebseinheit. Wenn die Antriebsrolle 5 in Pfeilrichtung 7 angetrieben wird, wird das Band 4 vorgeschoben. Die Antriebseinheit bildet dann eine Vorschubeinrichtung. Wenn sie in Pfeilrichtung 8 angetrieben wird, bildet sie die Spanneinrichtung. Insoweit kann die Anordnung als bekannt betrachtet werden (EP-B-297 337).The housing 1 of the tool contains one in its forehead Lock holder 2, in which a band channel 3 opens, which dash-dotted band 4 to one in the lock holder 2 located lock leads to in together with this to be processed in a known manner. During processing the tape 4 is advanced around the object to be bound to be looped. If its free end in that lock located in the lock holder 2 is bound, the tape 4 is pulled back around the looped around the tape Tension loop. For feeding and withdrawing the Tape serves one from the drive roller 5 and counter pressure rollers 6 existing drive unit. If the drive roller 5 in Direction of arrow 7 is driven, the tape 4 is advanced. The drive unit then forms a feed device. If it is driven in the direction of arrow 8, forms the tensioning device. In this respect, the arrangement can be known are considered (EP-B-297 337).

Zwischen der Schloßhalterung 2 und der Antriebseinrichtung 5, 6 ist die Bandspannungsmeßeinrichtung 10 angeordnet, die in einer dafür speziell vorgesehenen Halterung 11 des Gehäuses 1 leicht wechselbar untergebracht sind. Sie wird ebenso wie der Bandführungskanal 3 von dem Band 4 im wesentlichen geradlinig durchlaufen. Sie enthält ein Paar von Führungsrollen 12, die die oben erwähnten Bandführungen bilden. Ihnen mittig gegenüber ist eine Auslenkungsrolle 13 angeordnet, die die oben erwähnte Auslenkungsführung bildet. Die Auslenkungsrolle 13 ist an einer elektronischen Kraftmeßeinrichtung 14 angeordnet, die den in Pfeilrichtung 15 auf die Auslenkungsrolle 13 durch das Band 4 ausgeübte Kraft mißt. Die Rollen 12, 13 sind so angeordnet, daß der Berührungspunkt der Auslenkungsrolle 13 mit dem Band 4 wenig tiefer liegt als die geradlinige Verbindungslinie der Berührungspunkte der Bandführungsrollen 12 mit dem Band.Between the lock bracket 2 and the drive device 5, 6, the belt tension measuring device 10 is arranged, which in a holder 11 of the housing 1 provided for this purpose are easily exchangeable. It becomes just like that Belt guide channel 3 of the belt 4 is essentially straight run through. It contains a pair of guide rollers 12 which form the tape guides mentioned above. Opposite you in the middle a deflection roller 13 is arranged, which the above mentioned deflection guide forms. The deflection roller 13 is arranged on an electronic force measuring device 14, which in the direction of arrow 15 on the deflection roller 13 force exerted by the band 4 is measured. The rollers 12, 13 are so arranged that the point of contact of the deflection roller 13 with the band 4 is slightly lower than the straight connecting line the points of contact of the tape guide rollers 12 with the tape.

Dies ist in Fig. 2 in größerem Maßstab schematisch dargestellt. Die Kraft 15, die von dem Band 4 auf die Bandspannungsmeßeinrichtung 14 ausgeübt wird, hängt nur von der Bandspannung ab. Das Verhältnis, in welchem diese Kraft zur Bandspannung steht, wird bestimmt durch die geometrische Beziehung zwischen den Punkten 12 und 13, die mit großer Genauigkeit und Konstanz durch die Bauart der Bandspannungsmeßeinheit festgelegt ist. Das von der Bandspannungsmeßeinrichtung 14 erzeugte und im Display 19 angezeigte Signal kann daher unmittelbar als Bandspannung geeicht werden.This is shown schematically in Fig. 2 on a larger scale. The force 15 exerted by the belt 4 on the belt tension measuring device 14 exercised depends only on the Belt tension off. The ratio in which this force to Band tension is determined by the geometric relationship between points 12 and 13 with great accuracy and constancy through the design of the belt tension measuring unit is set. That from the tape tension measuring device 14 signal generated and shown in the display 19 can therefore are immediately calibrated as belt tension.

Es sei angenommen , daß die Antriebsrolle 5 über eine Rutschkupplung angetrieben ist, die derart einstellbar ist, daß das Rutschmoment der gewünschten maximalen Bandspannung entspricht. Wenn man während einiger Probeabbindungen am Display 19 die erzielte Bandspannung abliest, kann man manuell die Rutschkupplung auf die gewünschte Bandspannung einstellen. It is assumed that the drive roller 5 has a Slip clutch is driven, which is adjustable such that the slip torque of the desired maximum belt tension equivalent. If you look at the display during a few test sets 19 reads the tape tension achieved, you can manually adjust the slip clutch to the desired belt tension.

Dies kann auch selbsttätig geschehen, wenn man annimmt, daß die Einheit 18 eine motorische Verstelleinrichtung für die Rutschkupplung ist. Es sei weiter vorausgesetzt, daß die Einheit 18 eine Steuereinrichtung umfaßt, in der die gewünschte Bandspannung gespeichert ist und die im Falle einer Abweichung des über Leitung 20 herangeführten Signals von der gespeicherten Bandspannung eine entsprechende Verstellung der Rutschkupplung vornimmt. Diese Einrichtung wird stelbsttätig dafür sorgen, daß der durch die Rutschkupplung bestimmte Wert der Bandspannung stets mit geringer Toleranz der gewünschten Bandspannung gleicht.This can also happen automatically if one assumes that the unit 18 is a motorized adjustment device for the Slip clutch is. It is further assumed that the unity 18 comprises a control device in which the desired Belt tension is stored and in the event of a deviation of the signal brought in via line 20 from the stored one Band tension a corresponding adjustment of the Makes slip clutch. This facility becomes self-employed ensure that the value determined by the slip clutch the belt tension always with low tolerance of the desired Band tension equals.

Statt dessen kann auch angenommen werden, daß die Einheit 18 eine Schaltkupplung ist, die die Antriebsrolle 5 mit einem zugehörigen Motor verbindet oder davon löst. Ferner sei angenommen, daß die Einheit 18 eine Steuereinrichtung enthält, die einen eingestellten Sollwert der Bandspannung mit dem über Leitung 20 von der Bandspannungsmeßeinrichtung 14 herangeführten Signal vergleicht. Die Schaltkupplung ist geschlossen, wenn das von der Bandspannungsmeßeinrichtung stammende Signal geringer ist als die eingestellte Bandspannung. Erreicht des Signal diesen Wert, so wird die Schaltkupplung gelöst und der Spannvorgang abgebrochen.Instead, it can also be assumed that unit 18 is a clutch that the drive roller 5 with a connecting or detaching the associated motor. It is also assumed that the unit 18 contains a control device, a set setpoint of the belt tension with the via line 20 from the band tension measuring device 14 Signal compares. The clutch is closed, if that comes from the tape tension measuring device Signal is less than the set belt tension. Reached of the signal this value, the clutch is released and the tensioning process stopped.
