The wheel is provided with a tape roll support (13) which revolves together with the wheel. The feed mechanism (7) has a feed carriage (8) which moves parallel to the axis of rotation of the winding wheel or to the longitudinal axis of the objects (20) and a holding device (9) on side nearest the winding wheel for the start of the objects (20). The feed mechanism (7) has two rollers (10, 11), one above the other, which can be displaced vertically and whose axes of rotation are perpendicular to the longitudinal axis of the objects (2). One roll (10) acts as a feed length receiver (10'), the other roll (11) as a feed drive (11'). The feed carriage (18) is partially or fully synchronized with the feed drive (11') and the feed length is controlled by comparison of the reference and actual values in an electrical control programme unit (2).

Description

Die Erfindung betrifft eine Vorrichtung nach der Gattung des Oberbegriffs des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Eine solche bekannte Vorrichtung weist eine Einrichtung für einen Vorschub der Dinge auf, wobei diese aus einer umlaufenden Kette für den Vorschub der Dinge besteht und die Kette mit gleichmäßig angeordneten Greifklemmen für die zu bandagierenden Dinge versehen ist. Zum Pro­grammieren von Bandagierschritten sind entsprechende Reiter vorgesehen Durch die endliche räumliche Ausdehnung dieser Reiter sind die Bandagierschritte in ihrer Wahl eingeschränkt Ein automatisches Bandagieren vom nahen Anfang der Dinge ist hierbei nicht möglich.Such a known device has a device for feeding things, which consists of a revolving chain for feeding things and the chain is provided with uniformly arranged gripping clamps for the things to be bandaged. Corresponding tabs are provided for programming bandaging steps. Due to the finite spatial extent of these tabs, the bandaging steps are restricted in their choice. Automatic bandaging from the near beginning of things is not possible here.

Aufgabe der Erfindung ist es, eine Vorrichtung nach der Gattung des Oberbegriffs des Anspruchs 1 zu schaffen, die die oben genannten Nachteile nicht aufweist, die ein einfaches Bandagieren in beliebigen Bandagierschritten und Bandagierlängen ermöglicht, geringere Rüstzeiten benötigt und eine hohe Reproduziergenauigkeit im Banda­gieren aufweist.The object of the invention is to provide a device according to the preamble of claim 1, which does not have the disadvantages mentioned above, which enables simple bandaging in any bandaging steps and bandaging lengths, requires shorter set-up times and has a high reproducibility in bandaging.

Diese Aufgabe wird durch den kennzeichnenden Teil des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen gehen aus den Unteransprüchen hervor.This object is solved by the characterizing part of claim 1. Further advantageous embodiments emerge from the subclaims.

Ein besonders vorteilhaftes Anwendungsgebiet der Erfindung ist das programmierte Bandagieren von flexiblen Kabel­ strängen zu Kabelbäumen. Gemäß dem kennzeichnenden Teil des Anspruchs 1 wird durch einfache Handhabung an der Vorrichtung ein programmierbares Bandagieren ermöglicht.A particularly advantageous field of application of the invention is the programmed bandaging of flexible cables strands to wire harnesses. According to the characterizing part of claim 1, programmable bandaging is made possible by simple handling on the device.

Durch die in Nähe des Wickelrades angeordneten senkrecht übereinander angeordneten Rollen, wobei eine als Vorschub­längenmeßwertaufnehmer und die andere als Vorschubantrieb ausgebildet ist, wird ein Verdrehen der Dinge beim Bandagieren vorteilhafterweise verhindert.By means of the rollers arranged vertically one above the other in the vicinity of the winding wheel, one being designed as a feed length measuring transducer and the other as a feed drive, twisting of things during bandaging is advantageously prevented.

Zwecks Überwindung des endlichen Vorschubbereichs des Vorschubschlittens übernimmt kurz vor Erreichen des Vorschubschlittenwegendes der Rollenvorschubantrieb den weiteren Vorschub der Dinge, wobei der Anfang der Dinge von der Halteeinrichtung über eine Steuerung gelöst wird.In order to overcome the finite feed area of the feed slide, the roller feed drive takes over the further feed of things shortly before reaching the feed slide path end, the beginning of things being released by the holding device via a control.

Eine Bandvorratskontrollvorrichtung sorgt dafür, daß bei Erreichen eines bestimmten Bandrollenmindestdurch­messers der Bandagiervorgang gestoppt wird, damit durch Aufsetzen einer neuen Bandrolle das Bandagieren lückenlos fortgesetzt werden kann.A tape supply control device ensures that the taping process is stopped when a certain minimum tape roll diameter is reached, so that the taping can be continued without interruption by fitting a new tape roll.

Der Mindestdurchmesser der Bandrolle kann sowohl über eine Hebelmechnik wie auch über eine Lichtschranke kontrolliert werden.The minimum diameter of the belt reel can be checked using a lever technology as well as a light barrier.

Ein weiterer Vorteil ist darin zu sehen, daß die Vorrich­tung eine Bandabschneidvorrichtung aufweist, die nach Programmende eines Bandagiervorgangs oder bei Erreichen eines Bandrollenmindestdurchmessers das Band automatisch abschneidet.Another advantage is that the device has a tape cutting device that automatically cuts the tape after the end of a taping program or when a minimum tape roll diameter is reached.

Besonders präzises Bandabschneiden ergibt sich dadurch, daß die Bandabschneidvorrichtung mit einem senkrecht zum Band orientiertes, drehbares Messer versehen ist.Particularly precise tape cutting results from the fact that the tape cutting device with a vertical rotatable knife oriented to the band.

Durch eine elektrische Programmsteuerung ist die Vorrich­tung über entsprechende Software in kürzester Zeit für ein anderes Bandagierprogramm umrüstbar Auch lassen sich damit in kürzester Zeit sämtliche Bewegungsorgane der Vorrichtung gezielt umprogrammieren und logisch miteinander verknüpfen.By means of an electrical program control, the device can be converted to another bandaging program in the shortest possible time using appropriate software. All movement elements of the device can also be specifically reprogrammed and logically linked with one another in the shortest possible time.

Fig. 2 zeigt in einer Seitenansicht die Vorschubeinrich­tung 7 in einer Bandagieranfangsposition. Hierzu ist der Vorschubschlitten 8 von seiner linken, gestrichelten Ruheposition 19 mit der Halteeinrichtung 9 in das Wickel­rad 12 eingefahren, wobei mittels der Halteeinrichtung 9 der Anfang der zu bandgierenden Dinge 20 verbunden ist. Vorzugsweise eignet sich zum Bandagieren ein ein­seitig klebendes Band 21. In dieser Startposition liegen die Rollen 10, 11 soweit auseinander, daß der Vorschub­schlitten 8 ungehindert durch diese sich in die Start­position bewegen kann. Eine Draufsicht auf die Vorschub­einrichtung 7 nach Fig. 2 zeigt die Fig. 3. Für ein programmiertes Halten der Dinge 20 mittels der Halteein­richtung 9 steht diese in Wirkverbindung mit einem steuerbaren Hubzylinder 22, womit die Halteeinrichtung 9 steuerbar ist. Wie gestrichtelt angedeutet, ist einer­seits die Rolle 11 mit einem Motor 23 verbunden und andererseits ist der Vorschubschlitten 8 über eine steuerbare Kupplung 24 mit dem Motor 23 verbunden, der zugleich als Weggeberantrieb 23ʹ dienen kann. Zur Kontrolle bzw. Messung des vorgegebenen Weges kann der Vorschubschlitten 8 mit einer digitalisierten Weg­längenskala 25 versehen werden, die mittels des optischen Sensors mit der Steuerung 2 korrespondiert.Fig. 2 shows a side view of the feed device 7 in a bandaging start position. For this purpose, the feed carriage 8 is moved from its left, dashed rest position 19 with the holding device 9 into the winding wheel 12, the beginning of the things 20 to be taped being connected by means of the holding device 9. A tape 21 that is adhesive on one side is preferably suitable for bandaging. In this starting position, the rollers 10, 11 are so far apart that the feed carriage 8 can move unhindered into the starting position. 2 shows a plan view of the feed device 7 according to FIG. 3. For a programmed holding of the things 20 by means of the holding device 9, this is in operative connection with a controllable lifting cylinder 22, with which the holding device 9 can be controlled. As indicated by dashed lines, on the one hand the roller 11 is connected to a motor 23 and on the other hand the feed carriage 8 is connected to the motor 23 via a controllable coupling 24, which can also serve as a displacement drive 23ʹ. To check or measure the predetermined path, the feed carriage 8 can be provided with a digitized path length scale 25, which corresponds to the controller 2 by means of the optical sensor.

Nachdem der Vorschubschlitten 8 mit den Dingen 20 aus dem Bereich der beiden Rollen 10, 11 und dem Wickelrad 12 herausgefahren ist, fahren die beiden Rollen 10, 11 derart zusammen, daß sie in Kontakt mit den länglichen Dingen 20 stehen, daß einerseits die Rolle 10 als Meßwert­aufnehmer 10ʹ und andererseits die Rolle 11 als Vorschub­antrieb 11ʹ wirkt. Diese Position zeigt die Fig. 4, wobei die beiden Rollen 10, 11 bzw. der Vorschubantrieb 11ʹ von der Vorschubgeschwindigkeit synchron mit dem Vorschubschlitten 8 nach links in Richtung des Pfeiles 26 verläuft.After the feed carriage 8 with the objects 20 has moved out of the area of the two rollers 10, 11 and the winding wheel 12, the two rollers 10, 11 move together in such a way that they are in contact with the elongated objects 20 such that the roller 10 as a transducer 10ʹ and on the other hand, the roller 11 acts as a feed drive 11ʹ. This position is shown in FIG. 4, the two rollers 10, 11 and the feed drive 11ʹ of the feed speed runs synchronously with the feed carriage 8 to the left in the direction of arrow 26.

Eine Draufsicht auf die Vorschubeinrichtung 7 gemäß der Fig. 4 ist in der Fig. 5 dargestellt.A top view of the feed device 7 according to FIG. 4 is shown in FIG. 5.

Wird die maximale Weglänge des Vorschubschlittens 8 erreicht, ohne daß die Bandagierlänge der Dinge 20 ereicht ist, wird programmgemäß die Haltevorrichtung 9 vom Hubzylinder 22 gelöst, wodurch die Dinge 20 nach unten fallen und nun allein der Vorschubantrieb 11ʹ den Vorschub der Dinge 20 übernimmt. Diese Position ist in der Fig. 6 dargestellt.If the maximum path length of the feed carriage 8 is reached without the bandaging length of things 20 having been reached, the holding device 9 is released from the lifting cylinder 22 according to the program, as a result of which things 20 fall down and now the feed drive 11ʹ takes over the feeding of things 20. This position is shown in FIG. 6.

Eine Draufsicht auf die Vorschubeinrichtung 7 gemäß der Fig. 6 ist in der Fig. 7 dargestellt.A top view of the feed device 7 according to FIG. 6 is shown in FIG. 7.

Die Figuren 8 und 9 zeigen eine pneumatisch betriebene Bandabschneidvorrichtung 16, die sich in der passiven Position (Fig. 9) außerhalb des Wickelrades 12 befindet Diese Position 27 ist in der Fig. 8 dargestellt. Zum Abschneiden des Bandagierbandes 21 wird die Bandabschneid­vorrichtung 16 durch den Kolbenzylinder 28 in die ge­strichelte Position gebracht. Eine Draufsicht auf diese Position ist in der Fig. 9 dargestellt. Dann wird die Bandabschneidvorrichtung 16 weiter in die gestrichelte Position über den Kolbenzylinder 29 gebracht. Das Band 21 befindet sich in einem Schlitz 30, wobei ein senkrecht zum Band 21 orieniertes, über eine Achse 31 drehbares Messer 32 angeordnet ist und von einem Kolbenzylinder 33 antreibbar ist. Durch diesen Schnitt des Messers 32 um die Achse 31 wird ein sicherer Schnitt des Bandes 21 erreicht. Nach Beendigung des Schnitts wird die Bandabschneidvorrichtung 16 in umgekehrter Reihenfolge in die passive Position 27 (Fig. 8) von der Steuerung 2 gebracht.FIGS. 8 and 9 show a pneumatically operated tape cutting device 16, which is in the passive position (FIG. 9) outside the winding wheel 12. This position 27 is shown in FIG. 8. To cut the taping tape 21, the tape cutting device 16 is brought into the dashed position by the piston cylinder 28. A top view of this position is shown in FIG. 9. Then the band cutting device 16 is brought further into the dashed position via the piston cylinder 29. The band 21 is located in a slot 30, wherein a knife 32 oriented perpendicular to the band 21 and rotatable about an axis 31 is arranged and can be driven by a piston cylinder 33. This cut of the knife 32 about the axis 31 ensures a safe cut of the band 21. After completion of the cut, the tape cutting device 16 is brought into the passive position 27 (FIG. 8) by the controller 2 in the reverse order.

In der Fig. 10 und 11 ist eine Bandvorratskontrollvor­richtung 18 mit einer den Bandrollenmindestdurchmesser messenden Einrichtung 34 dargestellt, die bei Erreichen eines vorgegebenen Mindestdurchmessers den Bandagiervor­gang über eine Hebelmechanik 35 stoppt. Der Bandrollen­durchmesser wird von einer Rolle 36 abgetastet und je nach Bandrollendurchmesser den Hebel 37 über die ortsfeste Achse 38 bewegt, wodurch über die Achse 39 der Hebel 40 über die ortsfeste Achse 41 gemäß der Fig. 11 verschwenkt wird, wodurch ein Tasthebel 42 bei einem vorgegebenen Mindestdurchmesser in eine Ausneh­mung 43 fährt und mit einem anderen Ende ein Näherungs­schalter 44 aktiviert, der seinerseits über die Steuerung 2 den Bandagiervorgang beendet. Eine kontaktlose Bandvor­ratskontrollvorrichtung 18 wird mittels einer Licht­schranke 45 erreicht, wobei einerseits der Bandroller 46 ein Lichtsender 47 und andererseits ein Lichtempfänger 48 angeordnet ist, der die Funktion eines Näherungsschal­ters 44 aufweist.10 and 11, a tape supply control device 18 is shown with a device 34 measuring the minimum tape roll diameter, which stops the taping process by means of a lever mechanism 35 when a predetermined minimum diameter is reached.

Gemäß Fig. 15 wird in einem ersten Arbeitsschritt 1 der Anfang eines einseitig klebendes Bandes 21 an den Anfang des Kabelbaumes 55 angelegt. Nachdem die Schutzhaube (nicht dargestellt) das Wickelrad 12 abgesichert hat, beginnt der Bandagiervorgang bei einer Anzeige von 0 mm und endet nach einer Bandagierlänge von 1190 mm (= x₁). Danach wird das Band 21 automatisch von einer Bandabschneideinrichtung 16 abgeschnitten. In einem zweiten Schritt 2 wird der Kabelbaum 55 in Pfeilrich­tung mit einem Vorschub von 180 mm Länge (= y₁) bewegt. Dann öffnet sich automatisch die Schutzhaube zum manuellen Anlegen des Bandanfangs an den Kabelbaum 55 (Fig. 16), womit nach Schließen der Schutzhaube in einem dritten Schritt 3 der Kabelbaum 55 mit einer Wickellänge von 210 mm (= x₂) versehen wird. Nach dem automatischen Abschneiden des Bandes 21 öffnet sich automatisch die Schutzhaube. Eine Mitnehmerzange (Halteeinrichtung 9) wird in eine Anfangsposition gebracht, um das Kabelbaum­ende bzw. den Anfang mit der Mitnehmerzange zu verbinden (Fig. 17). Daran schließen sich die Arbeitsschritte 6 bis 8 gemäß der Fig. 17 bis 20 an.15, in a first step 1, the beginning of a tape 21 which is adhesive on one side is placed at the beginning of the wiring harness 55. After the protective cover (not shown) has secured the winding wheel 12, the bandaging process begins with a display of 0 mm and ends after a bandaging length of 1190 mm (= x₁). The tape 21 is then cut off automatically by a tape cutting device 16. In a second step 2, the wiring harness 55 is moved in the direction of the arrow with a feed of 180 mm in length (= y 1). Then the protective hood opens automatically for manual application of the beginning of the tape to the cable harness 55 (FIG. 16), so that after the protective hood is closed in a third step 3 the cable harness 55 is provided with a winding length of 210 mm (= x₂). After the automatic cutting of the tape 21, the protective hood opens automatically. A driver pliers (holding device 9) is brought into an initial position in order to connect the end of the wire harness or the beginning to the driver pliers (FIG. 17). This is followed by work steps 6 to 8 according to FIGS. 17 to 20.
