Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zum Einführen von mindestens zwei Fäden und dergleichen in eine Spulvorrichtung mit einer der Anzahl der Fäden entsprechenden Anzahl nebeneinander angeordneten Changiervorrichtungen und einer gleichen Anzahl sich auf einem Spulendorn befindlichen Spulenhülsen mit je einem Fandenfangmittel.The invention relates to a method and a device for inserting at least two threads and the like into a winding device with a number of traversing devices arranged next to one another corresponding to the number of threads and an equal number of bobbin tubes located on a bobbin mandrel, each with a trapping agent.

Das Verfahren beinhaltet weiter die Merkmale, dass die Fäden von einer Fadenabsaugvorrichtung übernommen und anschliessend an einzelne sich über der Spulvorrichtung befindliche Fadenführer gebracht, dann an eine sich oberhalb de Changiervorrichtungen befindliche Fadenführung und weiter an einzelne Fadenführer unterhalb der Changiervorrichtungen gelegt und dabei ausserhalb des Changierbereiches gehührt, anschliessend jeweils mittels des entsprechenden, sich unterhalb der Changiervorrichtungen befindlichen Fadenführers aus einer Ausgangslage am äusseren Ende des Spulendornes vor das entsprechende Fadenfangmittel gebracht und zum gleichzeitigen Erfassen gleichzeitig in die Fangmittel geführt werden.The method further includes the features that the threads are taken over by a thread suction device and then brought to individual thread guides located above the winding device, then to a thread guide located above the traversing devices and further to individual thread guides below the traversing devices and thereby being moved outside the traversing area , then in each case by means of the corresponding thread guide located below the traversing devices, brought from a starting position at the outer end of the spool in front of the corresponding thread catching means and simultaneously guided into the catching means for simultaneous detection.

Die Vorrichtung beinhaltet weiter die Merkmale, dass das Fadenfangmittel zum Beispiel ein Fangschlitz sein kann, sowie dass die Spulvorrichtung mit einer Fadenführungsleiste oberhalb der Changiervorrichtungen und pro Faden einem sich unterhalb der Changiervorrichtungen befindlichen Fadenführer, welcher aus einer Ausgangslage am äusseren Ende des Spulendorns in einer Bewegungsrichtung parallel zum Spulendorn in eine innere Lage verschiebbar ist, in welcher der Faden vor das entsprechende Fadenfangmittel gebracht wird, sowie mit Mitteln zum Versetzen der Fäden aus der Lage vor den Fadenfangmitteln in die Fadenfangmittel versehen ist.The device further includes the features that the thread catching means can be a catch slot, for example, and that the winding device with a thread guide bar above the traversing devices and per thread one thread guide located below the traversing devices, which from a starting position at the outer end of the spool in one direction of movement is parallel to the spool in an inner layer in which the thread is brought in front of the corresponding thread catcher, and is provided with means for moving the threads from the position in front of the thread catcher in the thread catcher.

Das Nebeneinanderreihen und doppelstöckige Aufeinanderstellen von Spulmaschinen einerseits und das mehrfädige Aufspulen andererseits sowie der Bedarf, alle Fäden gefahrlos und gleichzeitig allen Spulenhülsen zu übergeben, um gleichmässige Spulengewichte zu erhalten, verlangte einen Ersatz der manuellen EinzeIfadenübergabe.The side-by-side arrangement and double-tier stacking of winding machines on the one hand, and multi-thread winding on the other hand, as well as the need to hand over all threads safely and at the same time to all bobbin tubes in order to obtain uniform bobbin weights, required a replacement of the manual single-thread transfer.

Aus der deutschen Offenlegungsschrift 26 27 643 ist eine Vorrichtung gemäss dem Oberbegriff der Patentansprüche 1 und 2 bekannt.A device according to the preamble of claims 1 and 2 is known from German Offenlegungsschrift 26 27 643.

In dieser Vorrichtung werden die von einer Fadenführung oder einem Lieferwerk angelieferten Fäden mittels einer Fadenabsaugvorrichtung übernommen, anschliessend an einer Fadenleitstange stirnseitig vor der Spulvorrichtung mittels Führungskerben gemeinsam als Bündel, jedoch getrennt voneinander, gehührt. Anschliessend werden bei gleichzeitigem Bewegen der Fäden durch den Einführungsspalt der Spulvorrichtung diese Fäden mittels längs der Tragachse der Spulenhülsen bewegbarer, die Fäden übernehmender Fadenösen getrennt voneinander in einem der in einer Reihe angeordneten Spulenhülsen entsprechenden Abstand vor diese gebracht.In this device, the threads delivered by a thread guide or a delivery unit are taken over by means of a thread suction device, then, together with a thread guide rod on the end face in front of the winding device, by means of guide notches, as a bundle, but separately from one another. Subsequently, with simultaneous movement of the threads through the insertion gap of the winding device, these threads are moved separately from one another by means of thread eyelets movable along the supporting axis of the bobbin tubes, at a distance corresponding to the bobbin tubes arranged in a row.

Anschliessend wird ein die Fadenösen tragender Schwenkbalken für das gleichzeitige Einlegen der Fäden in die Fangschlitze der Hülsen gegen, respektive unter die Spulenhülsen geschwenkt.Subsequently, a swivel bar carrying the thread eyelets is pivoted against or under the bobbin sleeves for the simultaneous insertion of the threads into the catch slots of the sleeves.

Gleichzeitig mit dem Bewegen der Fadenösen werden die Fäden aus den Führungskerben der Fadenleitstange gehoben, damit sie sich frei der Fadenleitstange entlang in die der Fadenspannung entsprechende Lage bewegen können.Simultaneously with the movement of the thread eyelets, the threads are lifted out of the guide notches of the thread guide rod so that they can move freely along the thread guide rod into the position corresponding to the thread tension.

Das Bewegen der Fadenösen geschieht durch verschiebbare, die Fadenösen tragende Scheiben, die auf einer drehbaren Gewindespindel gelagert sind. Eine der Scheiben ist mit einem Innengewinde versehen und wird als Mutter (im weiteren Mutterscheibe genannt) von der sich drehenden Gewindespindel bewegt. Die übrigen Scheiben sind auf der Spindel gleitend verschiebbar angeordnet und untereinander durch Mitnehmerstangen verbunden.The thread eyelets are moved by displaceable disks which carry the thread eyelets and are mounted on a rotatable threaded spindle. One of the washers is provided with an internal thread and is moved as a nut (hereinafter referred to as the nut washer) by the rotating threaded spindle. The remaining disks are slidably arranged on the spindle and connected to one another by driver rods.

Die Nachteile der Vorrichtung liegen darin, dass die mögliche Ungenauigkeit der Scheiben respektive der Fadenpositionen vor dem Fangschlitz durch eine zusätzliche Bewegung parallel zur Achse des Spulendornes kompensiert werden muss, um sicher zu sein, dass jeder Faden auch wirklich vom Fangschlitz erfasst wird. Die mögliche Ungenauigkeit entsteht einerseits durch die ungenaue Positionierung der Mutterscheibe durch den Drehzahlauslauf der motorgetriebenen Spindel und andererseits durch die Möglichkeit, dass die Reibung zwischen Mitnehmerstange und Scheibe grösser sein kann als zwischen Spindel und Scheibe.The disadvantages of the device are that the possible inaccuracy of the disks or the thread positions in front of the catch slot has to be compensated for by an additional movement parallel to the axis of the bobbin mandrel, in order to be sure that each thread is actually caught by the catch slot. The possible inaccuracy arises on the one hand from the imprecise positioning of the nut washer due to the speed of the motor-driven spindle and on the other hand from the possibility that the friction between the drive rod and the washer can be greater than that between the spindle and the washer.

Durch diesen Umstand entsteht auch der nachteilige Verfahrensschritt, dass die Fäden über die Positionen der Fangschlitze in Achsrichtung hinausbewegt und gemeinsam wieder zurückgeführt werden müssen, um sicher zu sein, dass die Fäden von den Fangschlitzen erfasst werden.This circumstance also creates the disadvantageous process step that the threads have to be moved beyond the positions of the catch slots in the axial direction and must be returned together to be sure that the threads are caught by the catch slots.

Diese Nachteile zu beheben, ist Aufgabe der Erfindung. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe verfahrensmässig derart, dass beim Verschieben der Fäden vor die entsprechenden Fadenfangmittel diese zusätzlich oberhalb der Changiervorrichtungen durch in den Fadenlauf hineinbewegbare Fadenführer und andererseits, unterhalb des Spulendornes durch einzeln schwenkbare Fadenführer nacheinander übernommen und dadurch vor dem gleichzeitigen Erfassen aller Fäden durch die Fangmittel in einer Zwischenposition, in welcher die Fäden genau vor dem Fangmittel liegen, gehalten werden und, dass nach dem Erfassen der Fäden durch die Fangmittel, die sich oberhalb der Changiervorrichtungen befindlichen Fadenführer nicht mehr in den Fadenlauf hineinragen, so dass der einzelne Faden wieder von der entsprechenden Changiervorrichtung erfasst werden kann.The object of the invention is to remedy these disadvantages. The invention, as characterized in the claims, solves the task procedurally in such a way that when the threads are moved in front of the corresponding thread catching means, these are additionally taken up and above one another above the traversing devices by thread guides that can be moved into the thread path and, on the other hand, below the spool mandrel thereby, before the simultaneous grasping of the threads by the catching means, are held in an intermediate position, in which the threads lie exactly in front of the catching means, and that after the threads are grasped by the catching means, the thread guides located above the traversing devices are no longer in the thread path protrude so that the individual thread can be picked up again by the corresponding traversing device.

In einem Maschinengehäuse 1 einer Spulvorrichtung 2 ist eine Reibwalze und ein Spulendorn 4 drehbar gelagert (nicht gezeigt). Der Spulendorn 4 ist aus einer weggefahrenen Position (Ruheposition) (nicht gezeigt) in eine hochgefahrene Position (Arbeitsposition, Fig. und 2) und zurück bewegbar.In a machine housing 1 of a winding device 2, a friction roller and a winding mandrel 4 are rotatably mounted (not shown). The spool mandrel 4 can be moved from a moved away position (rest position) (not shown) to a raised position (working position, FIGS. 2 and 2) and back.

In der hochgefahrenen Position des Spulendornes 4 liegen auf diesem festklemmbare Spulenhülsen 5 an der Reibwalze 3 an und erhalten dadurch die gewünschte Drehzahl und Drehijchtung. An den Spulenhülsen 5 ist je ein Fangschlitz 6 zum Festklemmen eines darin gefangenen Fadens vorgesehen.In the raised position of the spool 4 rest on this clampable spool sleeves 5 on the friction roller 3 and receive thereby the desired speed and direction of rotation. A catch slot 6 is provided on the bobbin tubes 5 for clamping a thread caught therein.

In einem am Maschinengehäuse 1 befestigten Support 7 ist eine erste Fadenführungsleiste 8 verschiebbar gelagert. Die Verschieberichtungen 9a und 9b (Fig.4) sind durch das Zusammenwirken von im Support 7 befestigten Führungsbolzen 10 und in der Fadenführungsleiste 8 vorgesehenen Führungsschlitzen 71 gegeben. Die Verschiebung erfolgt in einer Richtung mittels eines Pneumatik-Kolbens 11, dessen Zylinder 12 am Support 7 befestigt (nicht gezeigt) ist, und in der anderen Richtung mittels einer Zugfeder 13. Die Zugfeder 13 ist zwischen einem Supportteil 7a und der Führungsleiste 8 eingespannt. Der Zylinderkopf 14 des Kolbens 11 liegt an der Stirnseite 15 der Führungsleiste 8 an.A first thread guide bar 8 is slidably mounted in a support 7 fastened to the machine housing 1. The displacement directions 9a and 9b (FIG. 4) are given by the interaction of guide bolts 10 fastened in the support 7 and guide slots 71 provided in the thread guide bar 8. The displacement takes place in one direction by means of a pneumatic piston 11, the cylinder 12 of which is attached to the support 7 (not shown), and in the other direction by means of a tension spring 13. The tension spring 13 is clamped between a support part 7a and the guide bar 8. The cylinder head 14 of the piston 11 bears against the end face 15 of the guide bar 8.

Unterhalb der Führungsleiste 8 ist eine zweite Führungsleiste 16 mittels eines an einem Spportteil 7b befestigten Lagerbocks 17 dreh- und verschiebbar gelagert.Below the guide bar 8, a second guide bar 16 is rotatably and displaceably mounted by means of a bearing block 17 fastened to a support part 7b.

Das Verschieben in der Vorwärtsrichtung geschieht mittels eines Pneumatik-Kolbens 18, dessen Zylinder 19 am Support 7 befestigt (nicht gezeigt) ist, und in der Rückwärtsrichtung mittels einer zwischen Lagerbock 17 und einer Nutenwalze 20 angeordneten Druckfeder 21. Die Nutenwalze 20 ihrerseits ist am einen Ende mit einer Welle 22 verbunden, an welcher am anderen Ende die Fadenführungsleiste 16 befestigt ist.The displacement in the forward direction takes place by means of a pneumatic piston 18, the cylinder 19 of which is fastened to the support 7 (not shown), and in the rearward direction by means of a compression spring 21 arranged between the bearing block 17 and a grooved roller 20. The grooved roller 20 in turn is at one End connected to a shaft 22 to which the thread guide bar 16 is attached at the other end.

Die Nutenwalze 20 hat eine Nute 23, die im Eingriff mit einem an einem Suportteil 7c befestigten Nutenstein 24 steht. Der Kolbenkopf 26 des Kolbens 18 liegt an der Stirnseite 25 (Fig. 4) der Nutenwalze 20 an.The grooved roller 20 has a groove 23 which is in engagement with a sliding block 24 fastened to a support part 7c. The piston head 26 of the piston 18 bears against the end face 25 (FIG. 4) of the grooved roller 20.

Die zweite Fadenführungsleiste 16 hat in gleichen Abständen A vier Führungskerben 27a, 27b, 27c und 27d. Diese Abstände entsprechen den gegenseitigen Abständen der Fängschlitze 6, der auf dem Spulendorn festgeklemmten Hülsen 5.The second thread guide strip 16 has four guide notches 27a, 27b, 27c and 27d at equal intervals A. These distances correspond to the mutual distances between the catch slots 6 and the sleeves 5 clamped on the spool mandrel.

Unterhalb der beiden Führungsleisten sind die an sich im allgemeinen bekannten Changiervorrichtungen 28 (Fig. 11, in Fig.2 2 andeutungsweise gezeigt) mit den Changierfadenführern 29 (Fig. 11) angeordnet, die in ihrem Changierbereich C (Fig. 3), in an sich bekannter Weise, den Faden für die Wickelbildung auf der Spulenhülse hin- und herführen.Beneath the two guide strips are the generally known traversing devices 28 (FIG. 11, shown in FIG. 2 as a hint) with the traversing thread guides 29 (FIG. 11) in their traversing area C (FIG. 3) known way, the thread for winding formation on the bobbin back and forth.

Unterhalb dieser Changiervorrichtung 28 ist im weiteren eine Fadenführer-Schwenkvorrichtung 30 (Fig. 5 und 11) vorgesehen. Diese Vorrichtung 30 umfasst eine Welle 31, die innerhalb einer. Hohlwelle 32 drehbar gelagert ist.Below this traversing device 28, a thread guide swiveling device 30 (FIGS. 5 and 11) is also provided. This device 30 comprises a shaft 31 which is within a. Hollow shaft 32 is rotatably mounted.

Die Hohlwelle 32 ihrerseits ist in einem im Gehäuseteil la (Fig. 5) eingelassenen Lager 33 und in einem in Supportteil 7d eingelassenen Lager 34 drehbar gelagert. Die axiale Fixierung der Hohlwelle 32 geschieht einerseits mittels eines Wellenbundes 37, der stirnseitig am Lager 33 anliegt und andererseits mittels eines im Supportteil 7d befestigten Lagerdeckels 38, der stirnseitig an der Hohlwelle 32 anliegt.The hollow shaft 32 in turn is rotatably supported in a bearing 33 embedded in the housing part la (FIG. 5) and in a bearing 34 recessed in the support part 7d. The axial fixation of the hollow shaft 32 takes place on the one hand by means of a shaft collar 37 which abuts the bearing 33 on the end face and on the other hand by means of a bearing cover 38 fastened in the support part 7d which abuts the hollow shaft 32 on the end face.

Auf der Hohlwelle 32 sind Fadenführerelemente 39a-d schwenkbar angeordnet, bestehend je aus einer auf der Hohlwelle 32 drehbar gelagerten Büchse 35 und einer daran befestigten Stange 40 sowie an der Stange 40 befestigten Fadenführern 41. An einem zur Stange 40 gehörenden und zu dieser leicht abgewinkelten (aus Fig. 8 ersichtlich) Stangenfortsatz 42 ist das freie Ende als Gleitschuch 43 ausgebildet.Thread guide elements 39a-d are pivotally arranged on the hollow shaft 32, each consisting of a bush 35 rotatably mounted on the hollow shaft 32 and a rod 40 fastened to it and thread guides 41 fastened to the rod 40. On a rod 40 belonging to the rod 40 and slightly angled to it (apparent from FIG. 8) rod extension 42, the free end is designed as a sliding block 43.

Eine einerseits an der Büchse 35 und andererseits an der Hohlwelle 32 befestigte Schraubenfeder 36 hat die Funktion, die Büchse 35 in Richtung B (Fig. 7 und 11), d. h. im Gegenuhrzeigersinn, vom freien Ende des Spulendornes her gesehen, zu drehen, um damit die Fadenführelemente 39a-d in dieser Richtung zu schwenken.A helical spring 36 fastened on the one hand to the bush 35 and on the other hand to the hollow shaft 32 has the function of the bush 35 in the direction B (FIGS. 7 and 11), i. H. counterclockwise, seen from the free end of the bobbin mandrel, to thereby pivot the thread guide elements 39a-d in this direction.

Ein in der Welle 31 verankerter und in Führungsschlitzen 71 und 72 (Fig.7) der Hohlwelle 32 resp. Büchse 35 geführter Mitnehmerdorn 47 verhindert einerseits axiale Bewegungen der Welle 31 und der Büchse 35 und beschränkt andererseits durch die Länge des Führungsschlitzes 72 der Hohlwelle 32 die Schwenkbewegung der Stangen 40 (genaue Funktion wird später beschrieben). Die Breite der Führungsschlitze 71 und 72 ist so gewählt, dass der Dorn 47 reibschlüssig darin geführt ist.An anchored in the shaft 31 and in guide slots 71 and 72 (Fig.7) of the hollow shaft 32 and Bush 35 guided driving mandrel 47 prevents axial movements of the shaft 31 and the bush 35 on the one hand and on the other hand limits the pivoting movement of the rods 40 by the length of the guide slot 72 of the hollow shaft 32 (exact function will be described later). The width of the guide slots 71 and 72 is selected so that the mandrel 47 is guided in it by friction.

Der Fadenführer 41 hat eine Fadenleitkerbe 44 (Fig. 9), gebildet aus den Fadenleitkanten 45 und 46. Die Fadenleitkanten 45 und 46 bilden einen Oeffnungswinkel a von weniger als 90°, z. B. einen Winkel von 60°.The thread guide 41 has a thread guide notch 44 (FIG. 9), formed from the thread guide edges 45 and 46. The thread guide edges 45 and 46 form an opening angle a of less than 90 °, e.g. B. an angle of 60 °.

Ebenfalls unterhalb der Changiervorrichtung 28 ist eine im wesentlichen parallel zur Spulendornachse verschiebbare Führungsschiene 48 (Fig. 1, 3 und 10) vorgesehen. Diese Schiene 48 dient zum Führen der Fadenführerelemente 39a-d (Fig. 5) mittels der Gleitschube 43 sowie der Fäden 49a, 49b, 49c und 49d während des Einführens der Fäden in die Spulmaschine.Also below the traversing device 28 is a guide rail 48 (FIGS. 1, 3 and 10) which can be displaced essentially parallel to the coil mandrel axis. This rail 48 is used to guide the thread guide elements 39a-d (FIG. 5) by means of the sliding block 43 and the threads 49a, 49b, 49c and 49d during the insertion of the threads into the winding machine.

Zu diesem Zweck ist die Schiene 48 auf der dem Spulendorn zugekehrten Innenseite 50 mit Fadenführungsstiften 51 versehen, während die gegenüberliegende Aussenseite 52 zur Führung der Gleitschuhe 43 dient.For this purpose, the rail 48 is provided on the inside 50 facing the spool with thread guide pins 51, while the opposite outside 52 serves to guide the sliding shoes 43.

Im weiteren ist die Schiene an der oberen Schmalseite 53 (Fig. 3) derart mit Stufen 54 versehen, dass der Abstand a zwischen der Stufenstirnseite 54a und dem Führungsstift 51 (Fig. 10a) gleich gross oder kleiner als die Gleitschuhbreite b (Fig. 9) ist.Furthermore, the rail on the upper narrow side 53 (FIG. 3) is provided with steps 54 such that the distance a between the step end face 54a and the guide pin 51 (FIG. 10a) is equal to or less than the sliding shoe width b (FIG. 9 ) is.

Die Teilung c (Fig. 10a), d. h. der Abstand von Stift zu Stift 51, was dem Abstand zwischen den Stirnseiten 54a entspricht, ist so gewählt, dass beim Einführen der Fäden 49a-d in die Spulmaschine mittels der Schiene 48, im Moment der Uebergabe der Fäden 49a-d von der ersten Führungsleiste 8 an die zweite Führungsleiste 16, die Fäden an der Führungsleiste 16 derart geführt sind, dass jeder Faden beim Weitergleiten an der Führungsleiste 16 in seine entsprechende Führungskerbe 27a-d gelangt. Die entsprechende Position der Schiene 48 ist in Fig. 1 mit der Strichpunktierten Darstellung der Fäden 49a-d angedeutet.The division c (Fig. 10a), d. H. the distance from pin to pin 51, which corresponds to the distance between the end faces 54a, is selected such that when the threads 49a-d are introduced into the winding machine by means of the rail 48, at the moment the threads 49a-d are transferred from the first guide bar 8 to the second guide bar 16, the threads are guided on the guide bar 16 in such a way that each thread passes into its corresponding guide notch 27a-d when it continues to slide on the guide bar 16. The corresponding position of the rail 48 is indicated in FIG. 1 with the dash-dotted representation of the threads 49a-d.

An der unteren Schmalseite ist die Schiene 48 durch einen Mitnehmer 55 mit dem Kolben 56 eines Pneumatik-Zylinders 57 verbunden, der seinerseits am Maschinengehäuse 1 befestigt ist.On the lower narrow side, the rail 48 is connected by a driver 55 to the piston 56 of a pneumatic cylinder 57, which in turn is attached to the machine housing 1.

Zum Drehen der Welle 31 dient ein Kurbeltrieb 58 (Fig. 5 und 6) bestehend aus einem Pneumatik-Zylinder 59, dessen Zylinderrückseite schwenkbar mit einem Gehäuseteil 1 b verbunden ist sowie einem Gelenkbolzen 60 für die Kraftübertragung zwischen einem am Kolbenende befestigten Gelenkteil 61 und einem am Wellenende 62 der Welle 31 befestigten Gelenkteil 63.A crank mechanism 58 (FIGS. 5 and 6) consisting of a pneumatic cylinder 59, the cylinder rear side of which is pivotally connected to a housing part 1 b and a hinge pin 60 for the transmission of force between a hinge part 61 fastened to the piston end and a articulated part 63 fastened to shaft end 62 of shaft 31.

Zum Drehen der Hohlwelle 32 wird in analoger Weise ein Kurbeltrieb 64 verwendet, bestehend aus einem mit dem Gehäuseteil 1 schwenkbar verbundenen Pneumatik-Zylinder 65, einem am Kolbenende befestigten Gelenkteil 66, einem am Wellenende 68 befestigten Gelenkteilpaar 67 und einem Gelenkbolzen 69 zur Kraftübertragung zwischen den Gelenkteilen 66 und 67.To rotate the hollow shaft 32, a crank mechanism 64 is used in an analogous manner, consisting of a pneumatic cylinder 65 pivotally connected to the housing part 1, a joint part 66 fastened to the piston end, a pair of joint parts 67 fastened to the shaft end 68 and a joint bolt 69 for power transmission between the Hinge parts 66 and 67.

Das Einführen von Fäden 49a, 49b, 49c und 49d in die Spulvorrichtung 2 geschieht folgendermassen :Threads 49a, 49b, 49c and 49d are introduced into the winding device 2 as follows:

1. Phase1st phase

Von Fadenführern 70a, 70b, 70c und 70d (Fig.1) oder einem Lieferwerk (nicht gezeigt) herkommende Fäden werden mittels einer sogenannten Saugpistole 74 oder einer äquivalenten Saugvorrichtung (nicht gezeigt) angesaugt, an die in Arbeitsposition gebrachte erste Fadenführungsleiste 8 (Fig. 11) und an die Fadenführungsstifte 51 geführt. Diese Lage der Fäden ist in Fig. 11 mit ausgezogener Linie dargestellt.Threads coming from thread guides 70a, 70b, 70c and 70d (FIG. 1) or from a delivery plant (not shown) are sucked in by means of a so-called suction gun 74 or an equivalent suction device (not shown), onto the first thread guide strip 8 brought into the working position (FIG. 11) and guided to the thread guide pins 51. This position of the threads is shown in Fig. 11 with a solid line.

Die Fäden sind in dieser Position von den Changierfadenführern 29 nicht mehr erfassbar und liegen im Raum zwischen der Fadenführungsleiste 8 und den Fadenführungsstiften 51 frei gespannt.In this position, the threads are no longer detectable by the traversing thread guides 29 and are freely tensioned in the space between the thread guide bar 8 and the thread guide pins 51.

Die Fadenführer 70a bis 70d bilden den Scheitelpunkt des Changierdreieckes und befinden sich in an sich bekannter Weise im wesentlichen senkrecht über der Mitte des Changierbereiches jeder Spulenhülse 5, in Fig. 3 andeutungsweise mit dem Bereich C gezeigt.The thread guides 70a to 70d form the apex of the traversing triangle and, in a manner known per se, are located essentially perpendicularly above the center of the traversing region of each bobbin tube 5, shown in FIG. 3 with region C.

Vor dem Führen der Fäden 49a bis 49d an die entsprechenden Fadenführungsstifte 51 wurde die Führungsschiene aus der in Fig. 3 gezeigten Ausgangsposition mittels Betätigung des Zylinders 57 (nicht beschrieben) in die in Fig. 1 gezeigte Arbeitsposition gebracht. Anschliessend wird durch Betätigung des Zylinders 59 die Welle 31 (Fig. 5) derart gedreht, dass die Fadenführerelemente 39a-d aus der in Fig. 11 mit punktierter Linie darsgestellten Ausgangsposition D in die mit gestrichelter Linie gezeigte Position Di geschwenkt werden. Dies geschieht indem der Mitnehmerdorn 47 durch diese Drehung aus der in Fig. 7 gezeigten Anlage im Führungsschlitz 72 in die in Fig. 11 gezeigte Position, d. h. in Anlage am anderen Ende des Führungsschlitzes 72 gelangt, so dass die Schraubenfeder 36 (Fig. 5) die Büchse 35 in Drehrichtung B (Fig. 11) so lange dreht, bis die Gleitschuhe 43 an der Schienenaussenseite 52 anliegen.Before the threads 49a to 49d were guided to the corresponding thread guide pins 51, the guide rail was brought from the starting position shown in FIG. 3 into the working position shown in FIG. 1 by actuating the cylinder 57 (not described). The shaft 31 (FIG. 5) is then rotated by actuating the cylinder 59 in such a way that the thread guide elements 39a-d are pivoted from the initial position D shown in FIG. 11 with a dotted line into the position Di shown with a broken line. This takes place in that the driving mandrel 47 by this rotation from the system shown in FIG. 7 in the guide slot 72 into the position shown in FIG. H. comes into contact with the other end of the guide slot 72, so that the helical spring 36 (FIG. 5) rotates the sleeve 35 in the direction of rotation B (FIG. 11) until the sliding shoes 43 rest against the rail outside 52.

Die Fäden liegen in dieser ersten Einführphase, wie in den Fig. 2 und 4 gezeigt, an der Führungsleiste 8 an, jedoch noch nicht an der ebenfalls bereits in die Arbeitsposition gebrachten zweiten Fadenführungsleiste 16.In this first insertion phase, as shown in FIGS. 2 and 4, the threads rest on the guide bar 8, but not yet on the second thread guide bar 16, which has also already been brought into the working position.

Aus Fig. 1 ist ersichtlich, dass die Fäden 49a und 49b, beim Verteilen vor die entsprechenden Fangschlitze 6 der Hülsen 5 erst dann der zweiten Fadenführungsleiste 16 übergeben werden können, wenn sie sich in den Positionen zwischen den Führungskerben 27b und 27a (Fig. 4) respektive 27b und 27c befinden. Aus diesem Grunde ist die zweite Phase, nämlich das Verteilen der Fäden 49a bis 49d vor die Fangschlitze 6 wie folgt gesteuert :It can be seen from FIG. 1 that the threads 49a and 49b, when distributed in front of the corresponding catch slots 6 of the sleeves 5, can only be transferred to the second thread guide strip 16 when they are in the positions between the guide notches 27b and 27a (FIG. 4 ) respectively 27b and 27c. For this reason, the second phase, namely the distribution of the threads 49a to 49d in front of the catch slots 6, is controlled as follows:

2. Phase2nd phase

Auf weiteren manuellen Knopfdruck (nicht gezeigt) beginnt der Pneumatik-Zylinder 57 den Kolben 56 und damit die Führungsschiene 48 aus der in Fig. 1 gezeigten in die in Fig. gezeigte Position zu verschieben. Etwas verzögert dazu, nämlich dann, wenn die Scheine 48 die in Fig. 1 mit strichpunktierten Linien dargestellte Position der Fäden erreicht hat, wird durch Entlastung des Zylinders 12 (Fig.4) die erste Fadenführungsleiste 8 mittels der Zugfeder 13 derart in Richtung 9b schräg zurück in die in Fig. 11 mit gestrichelter Linie dargestellte Ausgangsposition versetzt, dass die Fäden 49a bis 49d auf der zweiten Führungsleiste 16 jedoch noch nicht in den Führungskerben 27a-d zur Anlage kommen und daran weitergleiten, bis jeder Faden auf dem noch auf der Führungsleiste 16 zurückzulegenden Weg in der entsprechenden Führungskerbe 27a bis 27d angehalten wird, d. h. der Faden 49a in der Kerbe 27a, de Faden 49b in der Kerbe 27b, etc.Upon a further manual push of a button (not shown), the pneumatic cylinder 57 begins to move the piston 56 and thus the guide rail 48 from the position shown in FIG. 1 to the position shown in FIG. Slightly delayed, namely when the bills 48 have reached the position of the threads shown in dash-dotted lines in FIG. 1, by relieving the cylinder 12 (FIG. 4), the first thread guide strip 8 is inclined in the direction 9b in the direction 9b by means of the tension spring 13 11, that the threads 49a to 49d on the second guide bar 16 do not yet come into contact with the guide notches 27a-d and continue to slide until each thread on the one still on the guide bar 16 path to be covered is stopped in the corresponding guide notch 27a to 27d, d. H. the thread 49a in the notch 27a, the thread 49b in the notch 27b, etc.

Beim weiteren Zurückverschieben der Schiene 48 in die Ausgangsposition geben die Stufen 54 (Fig.3) den weiteren Schwenkweg der Fadenführer 41 (Fig. 11) frei, indem die Gleitschuhe 43 an den Stirnseiten 54a vorbei über die Stufen 54 schwenken. Diese Schwenkbewegung dauert so lange, bis die Büchse 35 (Fig. 7) mittels Führungsschlitz 71 am Mitnehmerdorn 47 anliegt (in Fig. 11 mit ausgezogenen Linien dargestellt). Bei diesem Vorgang werden die Fäden 49a-d von den Fadenführern 41 übernommen. Diese Lage der Fäden zwischen Fadenführer 41 und Kerbe 27a-d ist in Fig. 11 mit gestrichelter Linie dargestellt. Die räumlichen Relationen zwischen Gleitschuh 43 und Fadenführer 41 sind, um diese Fadenübernahme zu gewährleisten, derart, dass beim Durchschwenken des Gleitschuhs 43 über der entsprechenden Stufe die Leitkante 46 (Fig. 9) bereits dem Faden vorgelagert ist, in Blickrichtung der Spulendornachse und vom freien Ende des Spulendornes her gesehen, bevor der Gleitschuh 43 (Fig. 11) den Faden vom Führungsstift 51 wegschiebt. Der Abstand zwischen der Stirnseite 43a (Fig. 8) des Gleitschuhs und dem Faden ist deshalb grösser als der Abstand zwischen dem Faden und der Fingerspitze 46a. Um dies zu garantieren, muss bei gleicher Länge aller Gleitschuhe 43 der Stangenfortasatz 42 im wesentlichen parallel zur Aussenseite 52 der Schiene 48 sein. Ausserdem muss der in Fig. 9 gezeigte Abstand m grösser sein, als der in Fig. 10a gezeigte Abstand a.When the rail 48 is pushed back further into the starting position, the steps 54 (FIG. 3) release the further pivoting path of the thread guides 41 (FIG. 11) by the sliding shoes 43 pivoting past the end faces 54a over the steps 54. This pivoting movement lasts until the sleeve 35 (FIG. 7) lies against the driving mandrel 47 by means of a guide slot 71 (shown in solid lines in FIG. 11). In this process, the threads 49a-d are taken over by the thread guides 41. This position of the threads between thread guide 41 and notch 27a-d is shown in FIG. 11 with a broken line. In order to ensure this thread takeover, the spatial relationships between the sliding shoe 43 and the thread guide 41 are such that when the sliding shoe 43 swivels over the corresponding step, the leading edge 46 (FIG. 9) is already in front of the thread, in the direction of view of the spool axis and from the free End of the bobbin seen here before the shoe 43 (Fig. 11) pushes the thread away from the guide pin 51. The distance between the end face 43a (Fig. 8) of the sliding block and the thread is therefore larger than the distance between the thread and the fingertip 46a. To guarantee this, the rod extension 42 must be essentially parallel to the outside 52 of the rail 48 with the same length of all sliding shoes 43. In addition, the distance m shown in FIG. 9 must be greater than the distance a shown in FIG. 10a.

Am Ende dieser zweiten Phase liegen die Fäden 49a-d, wie in Fig.3 gezeigt und in Fig. 11 gestrichelt dargestellt, innerhalb der Spulvorrichtung zwischen den Kerben 27a-d und den Fadenführern 41 frei gespannt neben dem Changierbereich C sowie genau vor dem entsprechenden Fangmittel und im wesentlichen parallel zu diesem. Ausserdem bleibt der Zylinder 59 weiterhin im gleichen Sinn mit Druck beaufschlagt, wird jedoch am sich Weiterbewegen durch die genannte Anlage des Mitnehmerdornes 47 im Führungsschlitz 72 verhindert.At the end of this second phase, the threads 49a-d, as shown in FIG. 3 and shown in broken lines in FIG. 11, lie freely tensioned within the winding device between the notches 27a-d and the thread guides 41 next to the traversing area C and exactly in front of the corresponding one Fishing gear and essentially parallel to it. In addition, the cylinder 59 continues to be pressurized in the same sense, but is prevented from moving further by said abutment of the driving mandrel 47 in the guide slot 72.

3. Phase3rd phase

In dieser Phase wird der Pneumatik-Zylinder 65 (Fig. 5) betätigt und dadurch die Hohlwelle 32 in Richtung B (Fig. 7) gedreht. Damit wird das Weiterdrehen der Welle 31 ermöglicht, so dass die Fadenführerelemente 39a-d gemeinsam in die in Fig. 11 mit strichpunktierter Linie gezeigte Position F schwenken. Dadurch gelangen die Fäden 49a-d in die entsprechenden Fangschlitze 6 und werden von der Saugpistole 74 abgerissen, so dass die Windungen an der Hülse sich zu bilden beginnen.In this phase, the pneumatic cylinder 65 (FIG. 5) is actuated and the hollow shaft 32 is thereby rotated in the direction B (FIG. 7). This enables the shaft 31 to be rotated further, so that the thread guide elements 39a-d jointly pivot into the position F shown in broken lines in FIG. 11. As a result, the threads 49a-d get into the corresponding catch slots 6 and are torn off by the suction gun 74, so that the turns on the sleeve begin to form.

Der Hub des Zylinders 65 ist der Schwenkbewegung der Fadenführer 41 zwischen den Positionen E und F angepasst. Der Hub des Zylinders 59 ist derart, dass die Fadenführer zwischen Positionen D und F schwenkbar sind. Die Kraft des Zylinders 59 ist so bemessen, dass die Positionen, D, E und F von Hub und Kraft des Zylinders 65 gegeben sind.The stroke of the cylinder 65 is adapted to the pivoting movement of the thread guides 41 between the positions E and F. The stroke of the cylinder 59 is such that the thread guides can be pivoted between positions D and F. The force of the cylinder 59 is dimensioned such that the positions, D, E and F of the stroke and force of the cylinder 65 are given.

Nach dem Erreichen der Position F durch die Fadenführerelemente 39a-d wird der Pneumatik-Zylinder 19 (Fig. 5) entlastet. Dadurch versetzt die Feder 21 die Nutenwalze 20 und damit die zweite Fadenführungsleiste 16 zurück in die Ausgangsposition. Durch die dabei entstehende Drallbewegung wird die Führungsleiste 16 gleichzeitig gedreht und schwenkt die Kerben 27a-d aus dem Fadenlauf. Die Fäden 49a-d sind nun frei zwischen den Fadenführern 70a-d und den Hülsen 5 gespannt und streben infolge dieser Fadenspannung in den Changierbereich C, in dem sie durch die Changierfadenführer 29 erfasst werden. Während dieser Drallbewegung werden die Fäden durch die Kerben 27a-d derart geführt, dass zwischen Fangschlitz 6 und Changierbereich C einige Reservewindungen gelegt werden. Mit dem Erfassen der Fäden 49a-d durch die Changierfadenführer 29 beginnt der normale Aufwindvorgang.After the position F has been reached by the thread guide elements 39a-d, the pneumatic cylinder 19 (FIG. 5) is relieved. As a result, the spring 21 displaces the grooved roller 20 and thus the second thread guide strip 16 back into the starting position. As a result of the swirl movement that occurs, the guide bar 16 is rotated at the same time and pivots the notches 27a-d out of the thread path. The threads 49a-d are now freely stretched between the thread guides 70a-d and the sleeves 5 and, as a result of this thread tension, strive in the traversing area C, in which they are gripped by the traversing thread guides 29. During this twisting movement, the threads are guided through the notches 27a-d in such a way that some reserve turns are placed between the catch slot 6 and the traversing area C. The normal winding process begins when the threads 49a-d are gripped by the traversing thread guides 29.

4. Phase4th phase

Schliesslich werden die Zylinder 59 und 65 umgesteuert (nicht gezeigt), so dass die Fadenführerelemente 39a-d in die in Fig. 11 mit punktierter Linie dargestellte Position D zurückschwenken. Diese Ausgangsposition wird in Fig. 7 gezeigt.Finally, the cylinders 59 and 65 are reversed (not shown), so that the thread guide elements 39a-d pivot back into the position D shown in FIG. 11 with a dotted line. This starting position is shown in Fig. 7.

Eine Variante A der Erfindung ist in den Fig. 12 bis 15 dargestellt.A variant A of the invention is shown in FIGS. 12 to 15.

Diese Variante besteht darin, dass an Stelle der Büchse 35 (Fig. 5) und der Schraubenfeder 36 eine Schraubenfeder 75 einerseits mit der Stange 40 und andererseits mit einem in der Welle 31 verankerten Bolzen 76 verbunden ist. Die übrigen in Verbindung mit der Stange 40 stehenden Elemente sind die bereits beschriebenen und haben entsprechend dieselben Bezeichnungen. Zusätzlich verhindert ein zur Aufnahme der Elemente 75, 76 und 40 dienender muldenförmiger Anschlag 77 das Durchbiegen der Schraubenfeder 75 in dieser Richtung. Der Anschlag 77 ist mit seinem an die Welle 31 grenzenden Ende im Führungsschlitz 73 derart reibschlüssig geführt, dass dadurch axiale Verschiebungen der Welle 31 verhindert werden.This variant consists in that instead of the bush 35 (FIG. 5) and the coil spring 36, a coil spring 75 is connected on the one hand to the rod 40 and on the other hand to a bolt 76 anchored in the shaft 31. The remaining elements in connection with the rod 40 are those already described and accordingly have the same designations. In addition, a trough-shaped stop 77 serving to receive the elements 75, 76 and 40 prevents the coil spring 75 from bending in this direction. The stop 77, with its end adjoining the shaft 31, is guided in the guide slot 73 in such a frictional manner that axial displacements of the shaft 31 are thereby prevented.

Das Einführen der Fäden 49a-d in die Spulvorrichtung 2 geschieht wie früher beschrieben im wesentlichen mit der Ausnahme, dass das Durchschwenken der Fadenführer 41 über die Stufen 54 mittels Spannkraft der Schraubenfeder 75 erfolgt. Der folgende Beschreibungsteil ist deshalb auf die Funktion der neuen Elemente beschränkt :

  • In der 1. Phase wird, nachdem die Schiene 48 in die Arbeitsposition (Fig.1) gebracht wurde, die Welle 31 in Richtung B (Fig. 15) gedreht, bis der Anschlag 77 (Fig. 14) am Schlitzende 78 des Schlitzes 73 anliegt. In dieser Stellung liegen die Gleitschuhe 43 (vgl. Fig. 11) an der Schienenaussenseite 52 an, d. h. die Fadenführerelemente 39a-d sind in der in Fig. 15 mit gestrichelter Linie gezeigten Lage. In dieser Lage DI der Fadenführerelemente 39a-d ist die Schraubenfeder 75 entsprechend der Lage des Bolzens 76 und der Stange 40 gebogen (nicht gezeigt), d. h. sie liegt nicht am Anschlag 77 an.
The insertion of the threads 49a-d into the winding device 2 essentially takes place, as described earlier, with the exception that the thread guides 41 are pivoted through the steps 54 by means of the tensioning force of the helical spring 75. The following description section is therefore limited to the function of the new elements:
  • In the 1st phase, after the rail 48 has been brought into the working position (FIG. 1), the shaft 31 is rotated in the direction B (FIG. 15) until the stop 77 (FIG. 14) at the slot end 78 of the slot 73 is present. In this position, the sliding shoes 43 (see FIG. 11) rest against the rail outer side 52, ie the thread guide elements 39a-d are in the position shown in dashed lines in FIG. 15. In this position DI of the thread guide elements 39a-d, the coil spring 75 is bent in accordance with the position of the bolt 76 and the rod 40 (not shown), ie it does not abut the stop 77.

Beim Zurückverschieben der Schiene 48 in die Ausgangsposition geschieht der Schwenkvorgang in die mit ausgezogenen Linien dargestellte Position E der Fadenführerelemente 39a-d mittels der Spannkraft der Feder 75, und zwar bis die Feder 75 sowie das federseitige Ende der Stange 40 am Anschlag 77 anliegen. Der weitere Vorgang, d. h. das Drehen der Hohlwelle 32 und der Welle 31 zum Schwenken der Fadenführerelemente 39a-d in die Position F, etc., geschieht wie früher beschrieben.When the rail 48 is pushed back into the starting position, the pivoting operation into the position E of the thread guide elements 39a-d shown in solid lines takes place by means of the tensioning force of the spring 75, namely until the spring 75 and the spring-side end of the rod 40 bear against the stop 77. The further process, d. H. the turning of the hollow shaft 32 and the shaft 31 for pivoting the thread guide elements 39a-d into the position F, etc., takes place as described earlier.

Eine weitere Anwendungsmöglichkeit der Erfindung zeigt eine Variante B mit den Figuren 16-20. In dieser Variante besteht das Fadenführerelement 79 (Fig. 20) aus einem an einer Stange 40a befestigten Fadenführer 80 mit einer Fadenleitkerbe 81, gebildet aus einem langen Finger 82 und einem kurzen Finger 83.Another possible application of the invention is shown by variant B with FIGS. 16-20. In this variant, the thread guide element 79 (FIG. 20) consists of a thread guide 80 fastened to a rod 40a with a thread guide notch 81, formed from a long finger 82 and a short finger 83.

Die Stange 40a ist analog der Stange 40 an derselben Stelle der Büchse 35 befestigbar.The rod 40a can be fastened analogously to the rod 40 at the same location on the bush 35.

Die Funktionen beim Einführen der Fäden 49a-d in die Spulvorrichtung 2 entsprechen den für die Phasen 1-4 beschriebenen Funktionen mit der Ausnahme, dass die Fadenführer 80 direkt mittels der Stirnseiten 84 und 85 an der Aussenseite 52 der Führungsschiene 48 gleiten. Dies geschieht z. B. für den Faden 49d folgendermassen :The functions when inserting the threads 49a d in the winding device 2 correspond to the functions described for phases 1-4, with the exception that the thread guides 80 slide directly by means of the end faces 84 and 85 on the outside 52 of the guide rail 48. This happens e.g. B. for thread 49d as follows:

Beim Zurückfahren der Schiene 48 in die Ausgangsposition gleitet zuerst die Stirnseite 84 an der Aussenseite 52 und übergibt anschliessend beim Schwenken über die entsprechende Stufe 54 die Führung an den kurzen Finger 83.When the rail 48 moves back into the starting position, the end face 84 first slides on the outside 52 and then transfers the guidance to the short finger 83 when pivoting via the corresponding step 54.

Die Längen der beiden Finger 82 und 83 sind so gewählt, dass, nachdem der lange Finger 82 über der Stufe 54 liegt, die Stirnseite 84 die Innenseite 50 noch nicht erreicht hat, d. h. der Faden 49d am Finger 82 vorbeifährt.The lengths of the two fingers 82 and 83 are selected such that, after the long finger 82 lies above the step 54, the end face 84 has not yet reached the inside 50, i. H. the thread 49d passes the finger 82.

Erst nachdem auch der Finger 83 nicht mehr an der Aussenseite 52 geführt wird, d. h. dadurch das vollständige Schwenken des Fadenführers 80 über die Stufe 54 freigibt, wird der Faben 49d von der Fadenleitkerbe 81 erfasst und schwenkt weiter, bis die Stange 40a in der Position E zum Stillstand kommt. Dies geschieht unter der Voraussetzung, dass der Abstand k (Fig. 20) zwischen den Stirnseiten 84 und 85 grösser ist als der Abstand n zwischen der Stirnseite 54a der Stufe 54 und dem Führungsstift 51. Für die Abstände zwischen den Stirnseiten 54a der anderen Stufen und den weiteren Stiften 51 gilt dasselbe.Only after the finger 83 is no longer guided on the outside 52, i. H. thereby releasing the complete pivoting of the thread guide 80 via the step 54, the color 49d is gripped by the thread guide notch 81 and continues to pivot until the rod 40a comes to a standstill in position E. This takes place on the condition that the distance k (FIG. 20) between the end faces 84 and 85 is greater than the distance n between the end face 54a of the step 54 and the guide pin 51. For the distances between the end faces 54a of the other steps and the same applies to the other pins 51.

Nachdem alle Fäden 49a-d auf diese Weise erfasst wurden, erfolgt das weitere Vorgehen wie in den Phasen 3 und 4 beschrieben.After all threads 49a-d have been detected in this way, the further procedure is as described in phases 3 and 4.

Die Variante B kann auch mit der Variante A kombiniert werden.Variant B can also be combined with variant A.

Das beschriebene Verfahren sowie die Vorrichtung ist ebenfalls für andere Fadenfangvorrichtungen anwendbar, die neben den Hülsen z. B. am Spulendorn selbst vorgesehen sind. Solche Vorrichtung ersetzen die genannten Fangschlitze 6.The method described and the device can also be used for other thread catching devices, which in addition to the sleeves z. B. are provided on the mandrel itself. Such devices replace the aforementioned catch slots 6.

Ein solcher Spulendorn ist z. B. aus der US-PS 4106 711 und der GB-PS 1562 548 bekannt.Such a mandrel is z. B. from US-PS 4106 711 and GB-PS 1562 548 known.

Die dritte Phase geht mit dem in den genannten Patentschriften gezeigten Spulendorn mit der konischen Fadenleitfläche 11 und den Zähnen 12 wie folgt vor sich :

  • Die Fadenführerelemente 39a-d respektive 79 bringen den entsprechenden Faden 49a-d beim Schwenken in die Position F an die entsprechende Fläche 11. Durch die bestehende, von der Saugpistole erzeugte Fadenspannung gleitet der Faden auf der Fläche 11 in den Bereich der Zähne 12 und wird, wie in den Patentschriften beschrieben erfasst und abgeschnitten.
The third phase proceeds as follows with the bobbin mandrel with the conical thread guiding surface 11 and the teeth 12 shown in the aforementioned patents:
  • The thread guide elements 39a-d and 79, respectively, bring the corresponding thread 49a-d to the corresponding surface 11 when pivoting into the position F. Due to the existing thread tension generated by the suction gun, the thread slides on the surface 11 into the area of the teeth 12 and becomes as recorded and cut off as described in the patent specifications.

Die Lage einer Fläche 11 entlang des Spulendornes entspricht im wesentlichen der Lage eines Fangschlitzes 6.The position of a surface 11 along the coil mandrel essentially corresponds to the position of a catch slot 6.
