Description

Die Erfindung bezieht sich auf eine Spulenwechseleinrichtung an einer Spinnvorrichtung, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a bobbin changing device on a spinning device, according to the preamble of claim 1.

Eine Spinnvorrichtung der angegebenen Art ist beispielsweise aus dem Dokument CH-A-643 308 bekannt. Der auf dem freien Ende der Spindel bzw. der Spule anbringbare Fortsatz dient zum Aufwickeln eines kurzen Garnstücks neben der Spule, bevor diese von der Spindel abgenommen wird. Der Fortsatz wird insbesondere dann benötigt, wenn es nicht möglich ist, das kurze Garnstück neben dem anderen Ende der Spule z.B. auf die Spindel zu wickeln, beispielsweise weil die volle Spule wegen begrenzter Abmessungen des glockenförmigen Fadenführungsorgans nicht mehr in demselben Platz findet.A spinning device of the type specified is known, for example, from document CH-A-643 308. The extension which can be attached to the free end of the spindle or the bobbin serves to wind up a short piece of yarn next to the bobbin before it is removed from the spindle. The extension is needed especially when it is not possible to place the short piece of yarn next to the other end of the spool e.g. to wind on the spindle, for example because the full bobbin no longer fits in the same place due to the limited dimensions of the bell-shaped thread guide member.

Die Aufgabe der Erfindung besteht darin, eine Spulenwechseleinrichtung zur Verfügung zu stellen, die einen Spulenwechsel an einer Spinnvorrichtung der angegebenen Art vollkommen selbsttätig und in einfacher Weise durchführen kann.The object of the invention is to provide a bobbin changing device which can carry out a bobbin change on a spinning device of the type specified completely automatically and in a simple manner.

Die erfindungsgemässe Spulenwechseleinrichtung, mit der die Aufgabe gelöst wird, ist im kennzeichnenden Teil des Patentanspruchs 1 definiert.The bobbin changing device according to the invention, with which the object is achieved, is defined in the characterizing part of patent claim 1.

Ein Ausführungsbeispiel des Erfindungsgegenstandes wird nachstehend anhand der Zeichnungen näher erläutert. In diesen zeigen:

  • Fig. 1 schematisch eine Seitenansicht einer Spinnvorrichtung mit Elementen der Spulenwechseleinrichtung,
  • Fig. 2 in grösserem Massstab und teilweise im Schnitt das obere Ende der Spule in der Spinnvorrichtung, mit dem darauf angebrachten Fortsatz,
  • Fig. 3 eine Draufsicht zu Fig. 2 und
  • Fig. 4 bis 21 die Spinnvorrichtung in kleinerem Massstab bei verschiedenen Stellungen der Teile während eines Spulenwechselvorgangs.
An embodiment of the subject matter of the invention is explained below with reference to the drawings. In these show:
  • 1 schematically shows a side view of a spinning device with elements of the bobbin changing device,
  • 2 on a larger scale and partly in section, the upper end of the spool in the spinning device, with the extension attached to it,
  • Fig. 3 is a plan view of Fig. 2 and
  • 4 to 21 the spinning device on a smaller scale with different positions of the parts during a bobbin changing process.

Die dargestellte Spinnvorrichtung besitzt in üblicher Weise eine um ihre Achse drehbare Spindel 1, die auf einer Spindelbank 2 getragen ist. In der Spindelbank 2 ist der nicht dargestellte Drehantrieb für die Spindel 1, in der Regel ein Riemen, untergebracht. Die Spindelbank 2 ist an auf einem Fuss 3 stehenden Säulen 4 vertikal verschiebbar geführt. Der Verschiebeantrieb für die Spindelbank 2, z.B. über antreibbare Kettenräder laufende Ketten, ist ebenfalls nicht dargestellt. Auf dem oberen Ende der Säulen 4 ist eine Konsole 5 angeordnet, in der ein zur Spindel 1 koaxiales, glockenförmiges Fadenführungsorgan 6 drehbar gelagert ist. Die Konsole 5 enthält auch eine nicht dargestellte Antriebs- und/oder Bremseinrichtung für das Fadenführungsorgan 6. Der von einem Streckwerk kommende Faden 7 tritt oben in der Achse des Fadenführungsorgans 6 in dasselbe ein und verläuft dann im Inneren des Fadenführungsorgans 6 bis zu dessen unterem Rand. Bei diesem unteren Rand tritt der Faden durch eine Führungsöffnung 6.1 (nur in Fig. 2 dargestellt) und wird dann auf eine auf der Spindel 1 angeordnete Spulenhülse 8 gewickelt.The spinning device shown has in the usual way a spindle 1 which is rotatable about its axis and which is carried on a spindle bench 2. The spindle drive (not shown) for the spindle 1, usually a belt, is accommodated in the spindle bank 2. The spindle bench 2 is guided vertically displaceably on columns 4 standing on a base 3. The sliding drive for the spindle bench 2, e.g. Chains running over drivable sprockets are also not shown. On the upper end of the columns 4, a console 5 is arranged, in which a bell-shaped thread guide member 6 coaxial with the spindle 1 is rotatably mounted. The console 5 also contains a drive and / or braking device (not shown) for the thread guide element 6. The thread 7 coming from a drafting system enters the same at the top in the axis of the thread guide element 6 and then runs inside the thread guide element 6 up to its lower edge . At this lower edge, the thread passes through a guide opening 6.1 (only shown in FIG. 2) and is then wound onto a bobbin tube 8 arranged on the spindle 1.

Auf dem oberen Ende der Spindel 1 bzw. der Spulenhülse 8 ist lösbar ein Fortsatz 9 aufgesteckt, auf den vor einem Spulenwechsel ein Garnstück begrenzter Länge aufgewickelt wird.On the upper end of the spindle 1 or the bobbin tube 8, an extension 9 is detachably plugged onto which a piece of yarn of limited length is wound before a bobbin change.

Der Spulenwechsel wird von einer selbsttätig arbeitenden Spulenwechseleinrichtung durchgeführt, deren wesentliche Elemente die folgenden sind: Ein Spulenhalteelement 10, ein erstes Stützelement 11 und ein zweites Stützelement 12. Das Spulenhalteelement 10 und die Stützelemente 11 und 12 sind jeweils von einem nicht dargestellten Antrieb quer zur Achse der Spindel 1 bewegbar. Das Spulenhalteelement 10 kann beispielsweise die Form eines elastischen Zapfens haben, der in das obere Ende einer Spulenhülse 8 einsteckbar ist, um die Spulenhülse bzw. Spule zu halten. Das erste Stützelement 11 kann wie in Fig. 3 gezeigt ein gabelförmiges Element sein, das zwischen Flansche 9.1 und 9.2 (Fig. 2) des Fortsatzes 9 schiebbar ist, um den Fortsatz 9 gegen axiale Verschiebung zu halten. Das zweite Stützelement 12 kann ebenfalls ein gabelförmiges Element sein, das unter einen Spulenkörper schiebbar ist, um diesen gegen axiale Verschiebung zu halten.The bobbin change is carried out by an automatically operating bobbin changing device, the essential elements of which are the following: a bobbin holding element 10, a first supporting element 11 and a second supporting element 12. The bobbin holding element 10 and the supporting elements 11 and 12 are each driven transversely to the axis, not shown the spindle 1 is movable. The coil holding element 10 can for example have the shape of an elastic pin which can be inserted into the upper end of a coil sleeve 8 in order to hold the coil sleeve or coil. As shown in FIG. 3, the first support element 11 can be a fork-shaped element which can be pushed between flanges 9.1 and 9.2 (FIG. 2) of the extension 9 in order to hold the extension 9 against axial displacement. The second support element 12 can also be a fork-shaped element which can be pushed under a coil former to hold it against axial displacement.

Ferner ist auf dem Fuss 3 eine Transportvorrichtung für leere Spulenhülsen 8 und volle Spulen angeordnet, beispielsweise in Form eines in einer Schiene 13 senkrecht zur Zeichenebene laufenden Bandes 14, auf welchem Zapfen 15 zum Aufstecken jeweils einer Spule oder einer Spulenhülse getragen sind.Furthermore, a transport device for empty bobbin tubes 8 and full bobbins is arranged on the base 3, for example in the form of a band 14 running in a rail 13 perpendicular to the plane of the drawing, on which pins 15 are each carried for fitting a bobbin or a bobbin tube.

Für die Steuerung der Antriebe des Spulenhalteelementes 10 und der Stützelemente 11 und 12 sowie des Antriebes zum vertikalen Verschieben der Spindelbank 2 und des Antriebes des Transportbandes 14 während eines Spulenwechselvorganges ist eine selbsttätig arbeitende Steuereinrichtung (nicht dargestellt) vorhanden, welche die nachstehend anhand der Fig. 4 bis 21 beschriebenen Bewegungen der beschriebenen Teile bewirkt.For the control of the drives of the bobbin holding element 10 and the support elements 11 and 12 as well as the drive for the vertical displacement of the spindle bench 2 and the drive of the conveyor belt 14 during a bobbin changing process, an automatically operating control device (not shown) is available, which controls the following with reference to FIG. 4 to 21 described movements of the parts described causes.

Vor dem Abstellen der Spinnvorrichtung (d.h. der Drehantriebe der Spindel 1 und des glockenförmigen Fadenführungsorganes 6) wird die Spindelbank 2 auf die in Fig. 4 gezeigte Höhe eingestellt, so dass der Fortsatz 9 auf dem oberen Ende der vollen Spule 8.1 auf den unteren Rand des Fadenführungsorgans 6 ausgerichtet ist. Auf den Fortsatz 9 wird ein Garnstück begrenzter Länge aufgewickelt. Dann wird die Spinnvorrichtung abgestellt.Before switching off the spinning device (ie the rotary drives of the spindle 1 and the bell-shaped thread guide member 6), the spindle bank 2 is set to the height shown in FIG. 4, so that the extension 9 on the upper end of the full bobbin 8.1 on the lower edge of the Thread guide member 6 is aligned. A piece of yarn of limited length is wound onto the extension 9. Then the spinning device is turned off.

Anschliessend wird die Spindelbank 2 auf die in Fig. 5 gezeigte Höhe gesenkt, um den Fortsatz 9 auf die Höhe des ersten Stützelementes 11 auszurichten. In dieser Stellung sind die Teile auch in Fig. 2 dargestellt.The spindle bench 2 is then lowered to the height shown in FIG. 5 in order to align the extension 9 to the height of the first support element 11. In this position, the parts are also shown in Fig. 2.

Dann wird gemäss Fig. 6 das erste Stützelement 11 an eine Stelle in der Fortsetzung der Spindelachse bewegt, so dass nun das erste Stützelement 11 den Fortsatz 9 trägt und gegen weitere axiale Verschiebung festhält.6, the first support element 11 is then moved to a location in the continuation of the spindle axis, so that the first support element 11 now carries the extension 9 and holds it against further axial displacement.

Dann wird die Spindelbank 2 mit der auf der Spindel befindlichen Spule 8.1 in die Stellung gemäss Fig. 7 gesenkt, wobei der Fortsatz 9 vom Stützelement 11 zurückgehalten wird und der Faden zwischen dem Fortsatz 9 und der Spule 8.1 bricht, z.B. an einer scharfen Kante und/oder in einer Kerbe des unteren Flansches 9.1 des Fortsatzes 9.Then the spindle bench 2 with the bobbin 8.1 located on the spindle is lowered into the position according to FIG. 7, the extension 9 being held back by the support element 11 and the thread breaking between the extension 9 and the bobbin 8.1, e.g. on a sharp edge and / or in a notch of the lower flange 9.1 of the extension 9.

Danach wird wie in Fig. 8 gezeigt das Spulenhalteelement 10 an eine Stelle über der Spule 8.1 in der Fortsetzung der Spindelachse bewegt.Then, as shown in FIG. 8, the coil holding element 10 is moved to a location above the coil 8.1 in the continuation of the spindle axis.

Anschliessend wird die Spindelbank 2 wieder etwas gehoben, so dass das Spulenhalteelement 10 wie in Fig. 9 gezeigt in das obere Ende der Spule 8.1 eintritt, um diese festzuhalten.The spindle bench 2 is then raised again somewhat, so that the coil holding element 10, as shown in FIG. 9, enters the upper end of the coil 8.1 in order to hold it in place.

Dann wird wie in Fig. 10 gezeigt, das zweite Stützelement 12 unter die Spule 8.1 geschoben, um diese gegen axiale Verschiebung nach unten festzuhalten. Das zweite Stützelement 12 ist insbesondere dann erforderlich, wenn die Spindel 1 und die Spulenhülse 8 etwas konisch sind und daher fest aneinander haften.Then, as shown in FIG. 10, the second support element 12 is pushed under the coil 8.1 in order to hold it against axial displacement downwards. The second support element 12 is particularly necessary when the spindle 1 and the coil sleeve 8 are somewhat conical and therefore adhere firmly to one another.

Die Spindelbank 2 wird dann ganz nach unten in die in Fig. 11 gezeigte Stellung gesenkt, um die Spindel 1 aus der vom Spulenhalteelement 10 und vom zweiten Stützelement 12 gehaltenen Spule 8.1 herauszuziehen. Das zweite Stützelement 12 wird anschliessend wieder in seine Ausgangsstellung neben der Spindel zurückgezogen.The spindle bank 2 is then lowered all the way down to the position shown in FIG. 11 in order to pull the spindle 1 out of the coil 8.1 held by the coil holding element 10 and by the second support element 12. The second support element 12 is then pulled back into its starting position next to the spindle.

Das Spulenhalteelement 10 mit der Spule 8.1 wird dann in die in Fig. 12 gezeigte Stellung über einem leeren Zapfen 15 des Transportbandes 14 bewegt.The coil holding element 10 with the coil 8.1 is then moved into the position shown in FIG. 12 over an empty pin 15 of the conveyor belt 14.

Anschliessend setzt das Spulenhalteelement 10 die Spule 8.1 auf den genannten Zapfen 15 des Transportbandes 14 und zieht sich dann nach oben aus der Spule 8.1 zurück, wie in Fig. 13 gezeigt. (Der Zapfen 15 des Transportbandes hält die Spule 8.1 mit einer grösseren Kraft fest als das Spulenhalteelement 10.)Subsequently, the bobbin holding element 10 places the bobbin 8.1 on the mentioned pin 15 of the conveyor belt 14 and then withdraws upward out of the bobbin 8.1, as shown in FIG. 13. (The pin 15 of the conveyor belt holds the spool 8.1 with a greater force than the spool holding element 10.)

Das Transportband 14 wird dann um einen Schritt (= halbe Spindelteilung) senkrecht zur Zeichenebene weiterbewegt, um die volle Spule 8.1 wegzubringen und eine leere Spulenhülse 8 an deren Stelle zu verbringen (Fig. 14).The conveyor belt 14 is then moved one step (= half a spindle pitch) perpendicular to the plane of the drawing in order to remove the full bobbin 8.1 and to spend an empty bobbin tube 8 in its place (FIG. 14).

Das Spulenhalteelement 10 tritt dann oben in die Spulenhülse 8 ein und zieht diese von ihrem Transportbandzapfen 15.1 ab, siehe Fig. 15. (Der Zapfen 15.1 hält die Spulenhülse 8 weniger stark als das Spulenhalteelement 10.)The bobbin holding element 10 then enters the bobbin tube 8 at the top and pulls it off its conveyor pin 15.1, see FIG. 15. (The pin 15.1 holds the bobbin tube 8 less strongly than the bobbin holding element 10.)

Dann wird das Spulenhalteelement 10 mit der Spulenhülse 8 wieder an die Stelle in der Fortsetzung der Spindelachse bewegt, wie in Fig. 16 gezeigt.Then, the coil holding member 10 with the coil sleeve 8 is moved back to the position in the continuation of the spindle axis, as shown in FIG. 16.

Anschliessend wird die Spindelbank 2 gehoben, so dass die Spindel 1 wie in Fig. 17 gezeigt in die Spulenhülse 8 eintritt und sich in dieser festklemmt.The spindle bench 2 is then raised, so that the spindle 1 enters the coil sleeve 8 as shown in FIG. 17 and is clamped in it.

Die Spindelbank 2 wird dann gemäss Fig. 18 mit der Spulenhülse 8 wieder etwas gesenkt, um die Spulenhülse vom Spulenhalteelement 10 zu lösen.The spindle bank 2 is then lowered again somewhat with the coil sleeve 8 according to FIG. 18 in order to detach the coil sleeve from the coil holding element 10.

Das Spulenhalteelement 10 wird anschliessend wie in Fig. 19 gezeigt in seine Stellung neben der Spindel zurückgezogen, und die Spindelbank 2 wird mit der Spulenhülse 8 gehoben, bis der vom ersten Stützelement 11 getragene Fortsatz 9 in das obere Ende der Spulenhülse 8 eintritt.19 is then retracted into its position next to the spindle, as shown in FIG. 19, and the spindle bank 2 is raised with the coil sleeve 8 until the extension 9 carried by the first support element 11 enters the upper end of the coil sleeve 8.

Nun kann das erste Stützelement 11 wieder vom Fortsatz 9 zurückgezogen werden, Fig. 20.The first support element 11 can now be pulled back from the extension 9, FIG. 20.

Die Spindelbank 2 wird dann weiter gehoben, und die Spinnvorrichtung läuft wieder an, sobald der Fortsatz 9 mit dem daraufgewickelten kurzen Garnstück in das glockenförmige Fadenführungsorgan 6 eintritt. Fig. 21 zeigt die Stellung mit ganz angehobener Spindelbank 2, in welcher mit dem Bilden der neuen Wicklung auf dem unteren Ende der Spulenhülse 8 begonnen wird.The spindle bench 2 is then raised further, and the spinning device starts again as soon as the extension 9 with the short piece of yarn wound thereon enters the bell-shaped thread guide member 6. 21 shows the position with the spindle bank 2 fully raised, in which the formation of the new winding on the lower end of the bobbin tube 8 is started.
