  • the coil carriages are locked in a middle binding position and the binding machine is adjusted relative to the locked coil carriage until the belt guide is aligned with the respective passage groove.

After strapping the respective bundle, the drive for the coil carriage is switched on again and is moved past the light barrier until the next alignment mark is reached.

Description

Die Erfindung bezieht sich auf eine Anlage zum Binden von Bunden mittels eines um den Bundumfang geführten Bindebandes, bestehend aus einer eine Führung für das Bindeband aufweisenden Bindemaschine und aus einem mittels eines Antriebes quer zur Binderichtung verfahrbaren Bundwagen, der einen Bundsattel mit Durchtrittsnuten für das Bindeband trägt.The invention relates to a system for tying bundles by means of a binding band guided around the circumference of the bundle, consisting of a binding machine having a guide for the binding band and a bundle carriage which can be moved transversely to the binding direction by means of a drive and which carries a bundle saddle with passage grooves for the binding band .

Bei bekannten Anlagen dieser Art werden üblicherweise die zu bindenden Bunde mit Hilfe eines Bundwagens von einem Haspel zur Bindemaschine gefördert und dort mit einem Stahlband od. dgl. umreift, wobei das Bindeband z. B. mit einem durch die Durchtrittsnuten des Bundsattels greifenden Binderüssel unter dem jeweiligen Bund durchgezogen wird. Dabei ist es notwendig, die durch den Binderüssel gegebene Bandführung gegenüber den Durchtrittsnuten des Bundsattels auszurichten, was insbesondere dann zu Schwierigkeiten führt, wenn Bunde unterschiedlicher Höhe gebunden werden sollen, weil bei Bunden mit unterschiedlicher Höhe die Verteilung der Durchtrittsnuten über die Bundhöhe verschieden ist. Um diesen Schwierigkeiten zu begegnen, werden bei den bekannten Anlagen die Bundwagen in einer mittleren Bindestellung verriegelt und die Bindemaschine gegenüber dem verriegelten Bundwagen verstellt, bis die Bandführung gegenüber der jeweiligen Durchtrittsnut ausgerichtet ist. Nachteilig bei dieser Anordnung ist vor allem, daß die Bindemaschine verfahrbar gelagert und mit einem genauen Fahrantrieb versehen werden muß, um das Bindeband durch die gewünschte Durchtrittsnut mittels der Bandführung hindurchführen zu können. Außerdem ist die Bindefolge vergleichsweise gering, weil zunächst der Bundwagen in seine Verriegelungsstellung gebracht und dann die Bindemaschine gegenüber dem Bundwagen verfahren werden muß, bis die Bandführung gegenüber der jeweiligen Durchtrittsnut ausgerichtet ist.In known systems of this type, the bundles to be bound are usually conveyed from a reel to the binding machine with the aid of a coil carriage and strapped there with a steel band or the like. B. is pulled through with a through the through grooves of the collar saddle trunk under the respective collar. It is necessary to align the band guide provided by the binding trunk with respect to the passage grooves of the federal saddle, which leads to difficulties in particular when bundles of different heights are to be tied, because in bundles of different heights the distribution of the passage grooves across the federal government height is different. In order to counter these difficulties, in the known systems the coil carriages are locked in a middle binding position and the binding machine is adjusted relative to the locked coil carriage until the belt guide is aligned with the respective passage groove. A disadvantage of this arrangement is above all that the binding machine must be movably supported and provided with an accurate travel drive in order to be able to guide the binding tape through the desired passage groove by means of the tape guide. In addition, the binding sequence is comparatively low because first the coil carriage must be brought into its locking position and then the binding machine must be moved relative to the coil carriage until the tape guide is aligned with the respective passage groove.

Der Erfindung liegt somit die Aufgabe zugrunde, diese Mängel zu vermeiden und eine Anlage zum Binden von Bunden der eingangs geschilderten Art so zu verbessern, daß die Bandführung der Bindemaschine einfach, schnell und ohne Handsteuerung gegenüber den Durchtrittsnuten des Bundsattels ausgerichtet werden kann.The invention is therefore based on the object to avoid these deficiencies and to improve a system for binding bundles of the type described above so that the tape guide of the binding machine can be aligned easily, quickly and without manual control with respect to the passage grooves of the collar saddle.

Die Erfindung löst die gestellte Aufgabe dadurch, daß am Bundwagen wenigstens eine der Anzahl der benötigten Durchtrittsnuten gleiche Anzahl von im Abstand dieser Durchtrittsnuten voneinander angeordneten Richtmarken vorgesehen ist und daß der ortsfesten Bindemaschine eine den Antrieb des Bundwagens steuernde Abtasteinrichtung für die Richtmarken zugeordnet ist.The invention solves this problem in that at least one of the number of required through-grooves is provided on the coil carriage, the number of alignment marks arranged at a distance from one another and that the stationary binding machine is assigned a scanning device controlling the drive of the coil carriage for the alignment marks.

Durch das Vorsehen von Richtmarken in der Reihenfolge und im Abstand der benötigten Durchtrittsnuten wird mit einfachen Mitteln ein entsprechendes Ausrichten der Durchtrittsnuten gegenüber der Bindemaschine sichergestellt. weil die auf dem Bundwagen angeordneten Richtmarken lediglich von einer der ortsfesten Bindemaschine zugeordneten Abtasteinrichtung erfaßt zu werden brauchen, um über diese Abtasteinrichtung den Antrieb für den Bundwagen anzuhalten. Da bei der Anordnung der Abtasteinrichtung der Anhalteweg des Bundwagens ausreichend genau berücksichtigt werden kann, lassen sich die einzelnen Durchtrittsnuten über die ihnen zugeordneten Richtmarken nacheinander gegenüber der Bandführung der Bindemaschine ausrichten, ohne den Antrieb für den Bundwagen diesbezüglich besonders ausbilden zu müssen. Die Steuerung des Bundwagens erfolgt ja nicht über den Antrieb, sondern über eine Lageerfassung des Bundwagens, was nur einen entsprechenden Toleranzbereich für den Anhalteweg des Bundwagens erfordert. Ungenauigkeiten hinsichtlich der Spurführung des Bundwagens und des Antriebes können dabei ebenso unberücksichtigt bleiben, wie ein auftretender Schlupf beim Bundwagenantrieb. Da außerdem ein Verfahren der Bindemaschine unnötig wird, bleibt der Konstruktionsaufwand gering, obwohl die Bindefolge erhöht werden kann.The provision of alignment marks in the order and at a distance from the required through-grooves ensures simple alignment of the through-grooves with the binding machine with simple means. because the alignment marks arranged on the coil carriage need only be detected by a scanning device assigned to the stationary binding machine in order to stop the drive for the coil carriage via this scanning device. Since the stopping distance of the trolley can be taken into account with sufficient accuracy in the arrangement of the scanning device, the individual pass-through grooves can be aligned one after the other with respect to the band guide of the binding machine via the alignment marks assigned to them, without having to specially design the drive for the trolley in this regard. The bundle carriage is not controlled via the drive, but via a position detection of the bundle carriage, which only requires a corresponding tolerance range for the stopover path of the bundle carriage. Inaccuracies regarding the tracking of the coil carriage and the drive can also be disregarded, as can any slip that occurs with the coil carriage drive. In addition, since a binding machine process is unnecessary, the construction effort remains small, although the binding sequence can be increased.

Das Vorsehen von in ihrer Anordnung der Anordnung der Durchtrittsnuten entsprechenden Richtmarken bietet darüber hinaus die einfache Möglichkeit, die Steuerung an unterschiedliche Bundfolgen anzupassen. Zu diesem Zweck kann nämlich der Bundsattel austauschbar am Bundwagen angeordnet werden und die Richtmarken tragen. Mit dem Austausch eines Bundsattels wird somit eine unterschiedliche Aufeinanderfolge der Durchtrittsnuten und damit eine Anpassung an eine unterschiedliche Bundfolge möglich, ohne eine Umstellung der Steuerung vornehmen zu müssen. Die die Lage der Durchtrittsnuten angebenden Richtmarken sind ja am Bundsattel vorgesehen und werden mit diesen ausgetauscht. Die Austauschbarkeit der Bundsattel gewährleistet somit ein mittiges Binden auch von Schmalbunden, weil es nicht mehr dem Zufall überlassen bleiben muß, ob sich eine Durchtrittsnut im Endbereich oder im Mittenbereich eines Schmalbundes befindet, wie dies bei einer gleichmäßigen Verteilung der Durchtrittsnuten über die Sattellänge der Fall sein kann.The provision of alignment marks corresponding in their arrangement to the arrangement of the passage grooves also offers the simple possibility of adapting the control to different bundle sequences. For this purpose, the collar saddle can namely be arranged interchangeably on the coil carriage and carry the alignment marks. With the exchange of a fret saddle, a different sequence of the passage grooves and thus an adaptation to a different fret sequence is possible without having to change the control. The alignment marks indicating the position of the through grooves are provided on the collar saddle and are exchanged with them. The interchangeability of the collar saddle thus ensures that even narrow bundles are tied in the center, because it no longer has to be left to chance whether there is a passage groove in the end region or in the middle region of a narrow bundle, as is the case with a uniform distribution of the passage grooves over the saddle length can.

Eine Anpassung der möglichen Bindestellen an die jeweils auf dem Bundsattel aufgelegten Bunde braucht aber nicht über einen Austausch des Bundsattels zu erfolgen. Es kann auch der Bundsattel austauschbare bzw. verstellbare Bundauflagen aufweisen, zwischen denen sich die Durchtrittsnuten für das Bindeband ergeben. Werden die Bundauflagen verstellt, so müssen selbstverständlich auch die Richtmarken entsprechend verstellt werden können. Liegen vorgegebene Programme für die Bundfolge vor, so können die Richtmarken hinsichtlich ihrer Anzahl und ihrer Verteilung auf Tragleisten vorgegeben angeordnet sein, was das satzweise Austauschen der Richtmarken ermöglicht. Die für ein bestimmtes Programm vorbereiteten Tragleisten mit den Richtmarken brauchen nur .am Bundsattel befestigt zu werden, um eine programmgemäße Bindefolge sicherzustellen.However, it is not necessary to adapt the possible binding points to the bundles placed on the bund saddle by exchanging the bund saddle. The collar saddle can also have exchangeable or adjustable collar supports, between which the passage grooves for the binding band result. If the bundle supports are adjusted, it must of course also be possible to adjust the alignment marks accordingly. If there are predefined programs for the bundle sequence, the reference marks can be predefined in terms of their number and their distribution on support strips be arranged, which enables the exchange of the alignment marks in sets. The support strips with the alignment marks prepared for a specific program only need to be attached to the saddle to ensure a binding sequence in accordance with the program.

Als Abtasteinrichtung bieten sich zwar verschiedene Konstruktionen an, doch werden besonders einfache und störungsunanfällige Bedingungen erhalten, wenn die Abtasteinrichtung aus einer Lichtschranke besteht und die Richtmarken vor einem Spiegelband angeordnet sind, das das Licht der Lichtschranke zum lichtempfindlichen Empfänger reflektiert. Wird der Lichtstrahl durch eine Richtmarke vor dem Spiegelband unterbrochen, so erhält man über den Empfänger der Lichtschranke ein Steuersignal, das zum Anhalten des Bundwagenantriebes ausgenützt werden kann. Nach dem Umreifen des jeweiligen Bundes wird der Antrieb für den Bundwagen wieder eingeschaltet, der bis zum Erreichen der nächsten Richtmarke an der Lichtschranke vorbeibewegt wird. In Umkehrung der Verhältnissse können selbstverständlich auch die nicht abgedeckten Spiegelfelder als Richtmarken Verwendung finden, was an der Steuerung jedoch grundsätzlich nichts ändert.Although different constructions are available as the scanning device, particularly simple and fault-prone conditions are obtained if the scanning device consists of a light barrier and the alignment marks are arranged in front of a reflective tape that reflects the light from the light barrier to the light-sensitive receiver. If the light beam is interrupted by an alignment mark in front of the mirror band, a control signal is received via the receiver of the light barrier, which can be used to stop the coil carriage drive. After strapping the respective bundle, the drive for the coil carriage is switched on again and is moved past the light barrier until the next alignment mark is reached. In reverse of the conditions, the uncovered mirror fields can of course also be used as reference marks, but this does not fundamentally change the control.

  • Figur 2 den Bundwagen im Bereich der Bindemaschine in einer Stirnansicht in einem größeren Maßstab,
  • Figur 3 eine Draufsicht auf den Bundwagen und
  • Figur 4 den Bundwagensattel im Querschnitt.
The subject matter of the invention is shown in the drawing, for example. Show it
  • FIG. 1 shows a system according to the invention for tying bundles in a schematic top view,
  • FIG. 2 shows the coil carriage in the area of the binding machine in a front view on a larger scale,
  • Figure 3 is a plan view of the coil carriage and
  • Figure 4 shows the trolley saddle in cross section.

Wie der Zeichnung, insbesondere der Fig. 1, entnommen werden kann, besteht die dargestellte Anlage zum Binden von Bunden im wesentlichen aus einem Bundwagen 1, der auf Schienen 2 zwischen einem Aufwickelhaspel 3 und einer Bindestation 4 hin und her verfahren werden kann. Die Bindestation 4 weist dabei eine Bindemaschine 5 mit einer Führung 6 für das Bindeband, beispielsweise einen Binderüssel, auf, um das zum Umreifen der vom Haspel 3 abgenommenen Bunde dienende Bindeband unter dem Bund hindurchziehen zu können. Zu diesem Zweck ist der Bundsattel 7 des Bundwagens mit Durchtrittsnuten 8 zwischen den Bundauflagen 9 versehen, so daß die Bandführung 6 zwischen den Bundauflagen 9 durch die Durchtrittsnuten 8 hindurch unterhalb der aufliegenden Bunde durchgeführt werden kann.As can be seen from the drawing, in particular FIG. 1, the illustrated system for binding bundles essentially consists of a coil carriage 1 which can be moved back and forth on rails 2 between a take-up reel 3 and a binding station 4. The binding station 4 has a binding machine 5 with a guide 6 for the binding band, for example a binding trunk, in order to be able to pull the binding band used for strapping the bundles removed from the reel 3 under the bundle. For this purpose, the collar saddle 7 of the trolley is provided with passage grooves 8 between the collar supports 9, so that the band guide 6 between the collar supports 9 can be carried out through the passage grooves 8 below the overlying collars.

Der Bundsattel 7 ist in üblicher Weise auf einem Hubtisch 10 des Bundwagens 1 gelagert, der zur Führung des Hubtisches 10 eine mittige Säule 11 und zum Betätigen des Hubtisches zwei neben der Führungssäule 11 vorgesehene Hubzylinder 12 aufweist.The collar saddle 7 is mounted in a conventional manner on a lifting table 10 of the coil carriage 1, which has a central column 11 for guiding the lifting table 10 and two lifting cylinders 12 provided next to the guide column 11 for actuating the lifting table.

Damit nun die Durchtrittsnuten 8 gegenüber der Bandführung 6 ausgerichtet werden können, sind am Bundsattel 7 Richtmarken 13 angeordnet, und zwar in einer der Anzahl der Durchtrittsnuten 8 entsprechenden Anzahl und in einem dem Abstand der Durchtrittsnuten 8 voneinander entsprechenden gegenseitigen Abstand, wie dies der Fig. 3 entnommen werden kann. Diesen Richtmarken 13 ist eine Abtasteinrichtung 14 in der Bindestation 4 zugeordnet, die in ihrer Lage gegenüber der Bindemaschine 5 bzw. der Bandführung 6 festgelegt ist. Diese Abtasteinrichtung 14 ist über eine in Fig. 1 angedeutete Steuerleitung 15 und eine nicht näher dargestellte Steuereinrichtung mit dem Antrieb 16 des Bundwagens 1 verbunden, so daß beim Abtasten einer an der Abtasteinrichtung 14 vorbeibewegten Richtmarke das Abtastsignal zur Steuerung des Antriebes 16 ausgenützt werden kann. Der Antrieb 16 wird beim Ansprechen der Abtasteinrichtung 14 abgeschaltet und der Bundwagen entsprechend angehalten, wobei wegen des vorgegebenen Anhalteweges die Lage der das Ansprechen der Abtasteinrichtung auslösenden Richtmarke 13 und damit die Lage der dieser Richtmarke 13 zugehörigen Durchtrittsnut 8 vorbestimmt ist. Der Bundsattel 7 kann folglich hinsichtlich seiner Durchtrittsnuten 8 in einfacher Weise ausreichend genau gegenüber der Bandführung 6 ausgerichtet werden, so daß einer Umreifung des jeweiligen Bundes auf dem Bundwagen nichts im Wege steht.So that the passage grooves 8 can now be aligned with respect to the belt guide 6, 7 alignment marks 13 are arranged on the collar saddle, namely in a number corresponding to the number of passage grooves 8 and in a mutual distance corresponding to the distance of the passage grooves 8, as shown in FIG. 3 can be removed. These alignment marks 13 are assigned a scanning device 14 in the binding station 4, which is fixed in its position in relation to the binding machine 5 or the tape guide 6. This scanning device 14 is connected via a control line 15 indicated in FIG. 1 and a control device (not shown in more detail) to the drive 16 of the carriage 1, so that the scanning signal can be used to control the drive 16 when scanning an alignment mark moving past the scanning device 14. The drive 16 is switched off when the scanning device 14 responds and the coil carriage is stopped accordingly, the position of the alignment mark 13 triggering the actuation of the scanning device and thus the position of the passage groove 8 associated with this alignment mark 13 being predetermined due to the predetermined stopping distance. The collar saddle 7 can consequently be aligned with regard to its passage grooves 8 in a simple manner sufficiently precisely with respect to the belt guide 6, so that nothing stands in the way of strapping the respective collar on the coil carriage.

Aus Fig. 1 ist ersichtlich, daß auf dem Haspel 3 Schmalbänder 17 unterschiedlicher Breite aufgewickelt werden können, so daß die vom Bundwagen 1 aufzunehmende Bundfolge bezüglich der einzelnen Bundhöhen sehr unterschiedlich sein kann. Unterschiedlich breite Bänder 17 und damit unterschiedlich hohe Bunde verlangen jedoch eine Anpassung der Durchtrittsnuten 8 an die jeweilige Bundlage auf dem Bundsattel 7, wenn beispielsweise mittige oder endseitige Umreifungen der Bunde verlangt werden. Um eine solche Anpassung des Bundsattels 7 sicherzustellen, kann der Bundsattel 7 austauschbar am Hubtisch 10 des Bundwagens 1 gelagert sein. Durch einen Austausch des Bundsattels 7 können jeweils an die Bundfolge angepaßte Verhältnisse hinsichtlich der Lage der Durchtrittsnuten 8 gewährleistet werden. Da die Richtmarken 13 am Bundsattel 7 angeordnet sind und mit dem Bundsattel ausgetauscht werden, ergeben sich keinerlei Schwierigkeiten hinsichtlich einer Umrüstung der Steuerung.From Fig. 1 it can be seen that 3 narrow strips 17 of different widths can be wound on the reel, so that the bundle sequence to be picked up by the coil carriage 1 can be very different with respect to the individual coil heights. Bands 17 of different widths and thus bundles of different heights, however, require the passage grooves 8 to be adapted to the respective bundle position on the bund saddle 7 if, for example, central or end-side strapping of the bundles is required. In order to ensure such an adjustment of the collar saddle 7, the collar saddle 7 can be mounted interchangeably on the lifting table 10 of the collar carriage 1. By exchanging the collar saddle 7, conditions with respect to the position of the passage grooves 8 can be ensured which are adapted to the sequence of the collar. Since the alignment marks 13 are arranged on the collar saddle 7 and are exchanged with the collar saddle, there are no difficulties in converting the control.

An Stelle eines austauschbaren Bundsattels können aber auch die Bundauflagen 9 austauschbar bzw. verstellbar auf dem Bundsattel gelagert werden. Zu diesem Zweck sind nach den Fig. 3 und 4 im Bundsattel 7 zwei im Querschnitt T-förmige Längsnuten 18 vorgesehen, in die entsprechend geformte Klemmstücke 19 zur Befestigung der Bundauflagen 9 eingreifen. Gemäß dem dargestellten Ausführungsbeispiel sind jeweils zwei Bundauflagen 9 durch einen Verbindungssteg 20 miteinander zu einer Baueinheit verbunden, an dem die in die Klemmstücke 19 eingreifenden Klemmschrauben 21 angreifen. Die jeweils durch einen Verbindungssteg 20 verbundenen Bundauflagen 9 lassen sich durch diese Maßnahmen nicht nur einfach auf dem Bundsattel 7 verstellen, sondern bilden auch zwischen sich die Durchtrittsnut 8 für die Bandführung 6, so daß unabhängig von der jeweiligen Lage der Bundauflagen 9 der Durchtritt der Bandführung 6 sichergestellt ist.Instead of an interchangeable collar saddle, the collar supports 9 can also be interchangeably or adjustably mounted on the collar saddle. For this purpose, according to FIGS. 3 and 4, two longitudinal grooves 18 with a T-shaped cross section are provided in the collar saddle 7, into which correspondingly shaped clamping pieces 19 engage for fastening the collar supports 9. According to the exemplary embodiment shown, two collar supports 9 are connected to one another by a connecting web 20 to form a structural unit on which the clamping screws 21 engaging in the clamping pieces 19 engage. Each ver by a connecting web 20 bound collar supports 9 can not only be easily adjusted on the collar saddle 7 by these measures, but also form the passage groove 8 between them for the belt guide 6, so that the passage of the belt guide 6 is ensured regardless of the respective position of the collar supports 9.

Wird die Anzahl der Auflagen 9 oder deren Lage verändert, so muß zwangsläufig auch die Lage und Anzahl der Richtmarken 13 geändert werden. Dies kann durch eine Verstellung der Richtmarken 13 erfolgen, was allerdings eine verstellbare Lagerung der Richtmarken voraussetzt und eine Abhängigkeit von der richtigen Verstellung der Richtmarken mit sich bringt. Zur Vermeidung einer Richtmarkenverstellung können die Richtmarken 13 in vorgegebenen Abständen entsprechend den jeweiligen Bundfolgen auf Tragleisten 22 angeordnet werden, so daß bei einer geänderten Bundfolge lediglich die Tragleiste durch eine neue Tragleiste 22 mit einer an die neue Bundfolge angepaßten Richtmarkenanordnung ersetzt zu werden braucht. Damit sichergestellt ist, daß mit einer Verstellung der Bundauflagen 9 auch die Richtmarken 13 verstellt werden, könnten die Richtmarken 13 selbstverständlich auch mit den jeweils eine Durchtrittsnut 8 für die Bandführung 6 bildenden Bundauflagen 9 verbunden sein.If the number of pads 9 or their position is changed, then the position and number of alignment marks 13 must also be changed. This can be done by adjusting the alignment marks 13, which however presupposes an adjustable storage of the alignment marks and involves a dependence on the correct adjustment of the alignment marks. In order to avoid adjustment of the alignment marks, the alignment marks 13 can be arranged at predetermined intervals in accordance with the respective bundle sequences on support strips 22, so that in the case of a changed collar sequence, only the support strip needs to be replaced by a new support strip 22 with a alignment mark arrangement adapted to the new collar sequence. To ensure that the alignment marks 13 are also adjusted with an adjustment of the collar supports 9, the alignment marks 13 could of course also be connected to the collar supports 9 each forming a passage groove 8 for the band guide 6.

Als Abtasteinrichtung 14 eignet sich in besonders vorteilhafter Weise eine Lichtschranke, die mit einem Spiegelband 23 am Hubtisch 10 zusammenwirkt. Die Richtmarken 13 müssen dabei vor das Spiegelband 23 ragen, um eine Unterbrechung des Lichtstrahles der Lichtschranke zu gewährleisten. Als Steuersignal kann bei einer solchen Anordnung sowohl die Lichtunterbrechung als auch das Auftreten eines Lichtstrahles im Bereich des Empfängers ausgewertet werden. Da das Lichtband 23 am Hubtisch 10 angeordnet ist, braucht es nicht mit den Richtmarken 13 ausgetauscht zu werden.A light barrier which interacts with a mirror band 23 on the lifting table 10 is particularly suitable as the scanning device 14. The alignment marks 13 must protrude in front of the mirror band 23 in order to ensure an interruption of the light beam from the light barrier. With such an arrangement, both the light interruption and the occurrence of a light beam in the region of the receiver can be evaluated as the control signal. Since the light strip 23 is arranged on the lifting table 10, it does not need to be exchanged with the alignment marks 13.

Damit die vom Bundwagen 1 aufgenommenen Bunde in der gewünschten Weise umreift werden können, ist nicht nur eine entsprechende Lage der Durchtrittsnuten 8 auf dem Bundsattel 7, sondern auch eine axiale Ausrichtung der Bunde gegenüber dem Bundsattel erforderlich. Zu diesem Zweck trägt der Hubtisch 10 des Bundwagens 1 zwei Richtanschläge 24, die in Längsrichtung des Bundsattels 7 verschiebbar gelagert sind und über zwei gegensinnige Spindeln 25a und 25b gegengleich bezüglich der Längsmitte des Bundsattels 7 angetrieben werden können. Mit Hilfe der sich stirnseitig an die Bunde anlegenden Richtanschläge 24 können die Bunde in einfacher Weise in axialer Richtung gegenüber dem Bundsattel 7 ausgerichtet werden. Diese Ausrichtung der zu umreifenden Bunde gegenüber der Längsmitte des Bundsattels 7 stellt die richtige Lage der auf die Bandbreite der einzelnen Bunde abgestellten Anordnung der Durchtrittsnuten 8 bezüglich der einzelnen Bunde sicher.So that the bundles picked up by the coil carriage 1 can be strapped in the desired manner, not only is a corresponding position of the passage grooves 8 on the collar saddle 7, but also an axial alignment of the bundles with respect to the collar saddle necessary. For this purpose, the lifting table 10 of the coil carriage 1 carries two directional stops 24, which are mounted displaceably in the longitudinal direction of the coil saddle 7 and can be driven in opposite directions with respect to the longitudinal center of the coil saddle 7 by means of two opposing spindles 25a and 25b. With the help of the directional stops 24 resting against the end of the bundles, the bundles can be aligned in a simple manner in the axial direction relative to the collar saddle 7. This alignment of the bundles to be strapped relative to the longitudinal center of the collar saddle 7 ensures the correct position of the arrangement of the passage grooves 8, which is based on the bandwidth of the individual bundles, with respect to the individual bundles.

Werden bei einem Bundsattel 7 nicht alle vorgesehenen Durchtrittsnuten 8 zum Binden eines Bundes benötigt, so brauchen selbstverständlich nur jenen Durchtrittsnuten 8 Richtmarken 13 zugeordnet zu werden, die zum Durchziehen eines Bindebandes tatsächlich gebraucht werden. Wird die Richtmarkenanordnung nicht auf die tatsächlich benötigten Durchtrittsnuten abgestimmt, so müssen bei der Steuerung die den nicht benötigten Durchtrittsnuten zugehörigen Richtmarken übersprungen werden.If all of the passage grooves 8 provided for binding a bundle are not required for a collar saddle 7, then of course only 8 guide marks 13 need be assigned to those passage grooves that are actually needed for pulling a binding band. If the alignment mark arrangement is not matched to the passage grooves actually required, the control marks associated with the passage grooves not required must be skipped.

Auf Grund der Steuerung des Bundwagens über Richtmarken ist es möglich, in bestimmten Anwendungsfällen eine zweite Bindemaschine, die vorzugsweise auf der gegenüberliegenden Bundseite aufzustellen ist, der bestehenden Steuerung unterzuordnen.Due to the control of the coil carriage via alignment marks, it is possible in certain applications to subordinate a second binding machine, which should preferably be set up on the opposite side of the coil, to the existing control.
