Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Abnehmen von Textilhülsen, bzw. Textilspulen, welche an ihrem einen Ende von an einem bewegbaren Fördermittel angebrachten Zapfen gehalten sind und bei welcher die von den Zapfen getragenen Hülsen durch Schieben derselben gegen die Zapfen hin von diesen frei werden.The present invention relates to a device for removing textile sleeves or textile bobbins, which are held at one end by pins attached to a movable conveying means and in which the sleeves carried by the pins are free of them by pushing them against the pins will.

Es ist, insbesondere auf dem Gebiet der Spinnerei, z. B. aus der PCT-Veröffentlichung WO 81/00264, bekannt, Hülsen mit aus Fäden oder Vorgarn bestehenden Wicklungen an Zapfen, welche von einem umlaufenden Fördermittel getragen werden, aufzuhängen und wieder von diesen zu lösen. Zu diesem Zweck sind im allgemeinen sogenannte « Casablancazapfen » vorgesehen. Die Zapfen sind von solcher Art, dass beim Ueberschieben einer Hülse über den Zapfen die Hülse automatisch gehalten ist. Zur Freigabe der Hülse wird diese nochmals gegen den Zapfen gestossen, wodurch sie automatisch wieder vom Zapfen freigegeben wird. Ein Casablancazapfen ist in der britischen Patentschrift Nr. 1 093 949 beschrieben.It is, particularly in the field of spinning, e.g. B. from PCT publication WO 81/00264, known to hang sleeves with windings consisting of threads or roving on pegs, which are carried by a rotating conveyor, and to release them again. So-called "casablanca cones" are generally provided for this purpose. The pins are of such a type that the sleeve is automatically held when a sleeve is pushed over the pin. To release the sleeve, it is pushed against the pin again, whereby it is automatically released again by the pin. A casablanca cone is described in British Patent No. 1,093,949.

Es ist heute üblich, die auf die Zapfen aufgesteckten Hülsen, auch wenn sie bespult sind, von Hand von den Zapfen wegzunehmen. Die Entwicklung auf dem Textilgebiet bewegt sich heutzutage im Sinne der Herstellung immer grösserer und damit immer schwererer Spulen. Damit wird das manuelle Wegnehmen der Spulen immer mühsamer, besonders wenn diese sich noch in einer für das Bedienungspersonal unbequemen Höhe befinden.It is common today to remove the sleeves that have been attached to the pins, even if they are wound, by hand from the pins. The development in the textile field today moves in the sense of the production of ever larger and thus ever heavier bobbins. This makes manual removal of the coils more and more tedious, especially if they are still at an uncomfortable height for the operating personnel.

Dieser Nachteil soll gemäss der Erfindung behoben werden. Diese ist dadurch gekennzeichnet, dass zum Freigeben der Hülsen von den Zapfen ein Auflagekörper für die freien Enden der Hülsen vorhanden ist, welcher sich in der Bewegungsbahn der freien Enden der vom Fördermittel bewegten Hülsen befindet, und dass eine Anordnung vorgesehen ist, um jeweils bei einem auf dem Auflagekörper aufgesetzten, freien Ende je einer Hülse eine Verkleinerung des Abstandes zwischen dem die Hülse haltenden Zapfen und dem Auflagekörper herbeizuführen.This disadvantage is to be eliminated according to the invention. This is characterized in that for releasing the sleeves from the pins there is a support body for the free ends of the sleeves, which is in the path of movement of the free ends of the sleeves moved by the conveying means, and in that an arrangement is provided for each on the support body, the free end of each sleeve to bring about a reduction in the distance between the pin holding the sleeve and the support body.

Die Erfindung weist somit den Vorteil auf, dass sie einen weiteren Schritt in der Automatisierung und damit in der Reduzierung von Herstellungskosten auf dem Textilgebiet bildet.The invention thus has the advantage that it forms a further step in automation and thus in reducing manufacturing costs in the textile field.

Im folgenden sei die Erfindung anhand von Ausführungsbeispielen und der Zeichnung näher erläutert. In der letzteren sind die Figuren 1 und 2 schematische Darstellungen verschiedener Ausführungsformen der erfindungsgemässen Vorrichtung.The invention is explained in more detail below with the aid of exemplary embodiments and the drawing. In the latter, FIGS. 1 and 2 are schematic representations of various embodiments of the device according to the invention.

Gemäss der Ausführungsform nach Fig. 1 ist ein als Fördermittel dienendes endloses Band 11 vorgesehen. An diesem sind Halter 12 befestigt. Jeder Halter 12 umfasst, schwenkbar angeordnet, einen Zapfen 13, welcher zum Tragen je einer Spule 14 dient. Wie auch aus der erwähnten britischen Patentschrift ersichtlich, sind die Zapfen 13 in der Weise ausgeführt, dass beim Stülpen eines Endes der Hülse 15 über den Zapfen 13, die Hülse 15 durch den Zapfen 13 gehalten wird und durch ein darauffolgendes nochmaliges Stossen oder Schieben der Spule 14, bzw. Hülse 15 gegen den Zapfen 13 dieser die Hülse 15 wieder frei gibt. Ein typisches Beispiel eines solchen Zapfens 13 ist der bereits eingangs erwähnte « Casablancazapfen • : In Fig. 1 sind nur die eine halbkreisförmige Umkehrstelle und die anliegenden Teile des oberen und unteren Trums des endlosen Bandes 11 gezeigt. An dieser Umkehrstelle bewegen sich die Halter 12 vom oberen zum unteren Trum des Bandes 11.According to the embodiment according to FIG. 1, an endless belt 11 serving as a conveying means is provided. Holders 12 are attached to this. Each holder 12 comprises, pivotably arranged, a pin 13, which is used to carry one coil 14 each. As can also be seen from the aforementioned British patent, the pins 13 are designed in such a way that when one end of the sleeve 15 is placed over the pin 13, the sleeve 15 is held by the pin 13 and by a subsequent pushing or pushing of the coil again 14, or sleeve 15 against the pin 13, this releases the sleeve 15 again. A typical example of such a pin 13 is the "Casablanca pin" already mentioned at the beginning: in FIG. 1 only the one semicircular reversal point and the adjacent parts of the upper and lower run of the endless belt 11 are shown. At this reversal point, the holders 12 move from the upper to the lower run of the belt 11.

Unterhalb der halbkreisförmigen Ulkehrstelle befindet sich ein am Maschinengestell befestigter Auflagekörper 16, welcher einen Anschlag 17 umfasst. Der letztere befindet sich in der durch die freien, unteren Enden der Hülsen 15 im Betrieb der Vorrichtung gegebenen Bewegungsbahn 18, wobei diese freien unteren Enden der Hülsen 15 im Betrieb des Bandes 11 nacheinander auf dem Anschlag 17 auftreffen.Below the semicircular turning point there is a support body 16 fastened to the machine frame and comprising a stop 17. The latter is located in the movement path 18 given by the free, lower ends of the sleeves 15 during operation of the device, these free lower ends of the sleeves 15 hitting the stop 17 one after the other during operation of the band 11.

Die Freigabe der Hülsen 15 erfolgt mit dem Aufsetzen derselben auf den Anschlag 17, so dass der Ort, an dem sich die aufgesetzten Hülsen befinden, d. h. an dem sich die untere der zwei gezeichneten Spulen 14 befindet, im folgenden als Freigabestelle bezeichnet ist. Unmittelbar am Anlagekörper 16 befindet sich eine Rutsche 21. Diese dient zum Abfangen und Weiterbewegen der von den Haltern 12 frei werdenden Hülsen 15, bzw. Spulen 14. Zum Vermindern der Geschwindigkeit der in die Rutsche 21 gelangenden Spulen 14 ist eine mit diesen zusammenwirkende Bremsfeder 22 vorgesehen. Die Rutsche 21 kann auch als unter dem Gewicht der Spulen 14 kippbar ausgeführt sein. Eine solche Ausführungsform wird beispielsweise erhalten, indem die Rutsche 21, wie in Fig. 1 gezeigt, als um eine Achse 23 kippbar ist.The release of the sleeves 15 takes place when the same is placed on the stop 17, so that the location at which the sleeves are located, i. H. where the lower of the two drawn coils 14 is located, hereinafter referred to as the release point. A slide 21 is located directly on the contact body 16. This slide serves to intercept and move the sleeves 15 or coils 14 that are released from the holders 12 intended. The slide 21 can also be designed to be tiltable under the weight of the coils 14. Such an embodiment is obtained, for example, by the chute 21, as shown in FIG. 1, being tiltable about an axis 23.

Im Betrieb der Vorrichtung werden die Spulen 14, bzw. Hülsen 15, vom Band 11 mitgenommen. Dabei hangen sie als Folge ihres Gewichtes und der schwenkbaren Befestigung der Zapfen 13, nach unten. Ihre freien Enden bewegen sich längs der strichpunktiert gezeichneten Bewegungsbahn 18. Mit ihrem Eintreffen in die Freigabestellung gelangt das untere freie Ende der Hülsen 15 in Anlage mit dem Anschlag 17 des Auflagekörpers 16. Dadurch kann sich die Hülse 15 nicht mehr weiter nach unten bewegen. Dies kommt einem Vorgang gleich, bei welchem die Hülse 15 gegen den Zapfen 13 gestossen wird, wobei das obere Ende der Hülse 15 noch weiter über den Zapfen 13 gestülpt wird. Damit löst sich die durch den Zapfen 13 vermittelte Halterung, und unter gleichzeitigem Verschwenken des Zapfens 13 wird die Hülse 15 freigegeben. Bei der Weiterbewegung des Halters 12 wird der Zapfen 13 aus der Hülse 15 herausbewegt. Durch die strichpunktiert gezeichneten Spulenlagen ist gezeigt, wie die Spulen 14 in die Rutsche 21 hineinfallen. Es ist ein Merkmal dieser Ausführungsform, dass für einen einwandfreien Ablauf des Freigabevorganges die Zapfen 13 eine Bewegungsbahn definieren, deren Abstand vom Auflagekörper 16 in der Richtung gegen die Freigabestelle hin abnehmend ist.During operation of the device, the coils 14 or sleeves 15 are carried along by the belt 11. They hang down due to their weight and the pivotable attachment of the pin 13. Their free ends move along the dash-dotted line of motion 18. When they arrive in the release position, the lower free end of the sleeves 15 comes into contact with the stop 17 of the support body 16. As a result, the sleeve 15 can no longer move downward. This is equivalent to a process in which the sleeve 15 is pushed against the pin 13, the upper end of the sleeve 15 being pushed even further over the pin 13. This releases the bracket provided by the pin 13, and the sleeve 15 is released while simultaneously pivoting the pin 13. When the holder 12 moves further, the pin 13 is moved out of the sleeve 15. Through the Dash-dot drawn coil layers show how the coils 14 fall into the slide 21. It is a feature of this embodiment that, for the release process to run smoothly, the pins 13 define a movement path, the distance from the support body 16 decreasing in the direction towards the release point.

Die freie Spule 14 wird von einer sich unmittelbar am Auflagekörper 16 befindlichen Transporteinrichtung aufgenommen und durch diese weiterbewegt. Im vorliegenden Beispiel besteht diese Transporteinrichtung aus der Rutsche 21. Um zu vermeiden, dass schwere Spulen 14 mit zu grosser Wucht nach unten gleiten, werden diese mittels der Bremsfeder 22 gebremst. Anderseits wird eine sanfte Uebergabe der Spulen 14 an die Rutsche 21 erhalten, wenn man diese, z. B. in der bereits erwähnten Weise, um die Achse 23 kippbar ausführt. Für die weitere Behandlung der Spulen 14 können an sich auch irgendwelche andere Transporteinrichtungen vorgesehen sein.The free coil 14 is picked up by a transport device located directly on the support body 16 and is moved further by this. In the present example, this transport device consists of the chute 21. In order to prevent heavy coils 14 from sliding downward with excessive force, they are braked by means of the brake spring 22. On the other hand, a gentle transfer of the coils 14 to the chute 21 is obtained if one z. B. in the manner already mentioned, about the axis 23 tiltable. For the further treatment of the coils 14, any other transport devices can be provided.

In Fig. 2 ist eine weitere Ausführungsform der Erfindung gezeigt. Gemäss dieser dient eine Kette 31, welche sich im Betrieb der Vorrichtung in der Richtung des Pfeiles 36 von rechts nach links bewegt, als Fördermittel. Die Kette 31 ist mit Haltern 12 versehen, welche wiederum je einen schwenkbaren Zapfen 13 der im vorherigen beschriebenen Art umfassen.A further embodiment of the invention is shown in FIG. According to this, a chain 31, which moves from right to left in the direction of arrow 36 during operation of the device, serves as a conveying means. The chain 31 is provided with holders 12, which in turn each comprise a pivotable pin 13 of the type described above.

Die Zapfen 13 dienen wiederum zum Tragen von an diesen aufgehängten Spulen 14, welche wiederum auf Hülsen 15 aufgespult sind. Die freien unteren Enden der Hülsen 15 bewegen sich dabei längs der horizontalen Bewegungsbahn 19. Unterhalb der Kette 31 ist ein Körper 32 vorgesehen. Dieser umfasst drei Rollen 33, 34 und ein in der Richtung des Pfeiles 35 umlaufendes Band 37. Wie aus Fig. 2 ersichtlich ist, ist der gegenseitige Abstand der Kette 31 und des oberen Trums des Bandes 37 im gemäss Fig. 2 auf der rechten Seite der Rolle 34 befindlichen Teil des Körpers 32 gegen die Rolle 34 hin abnehmend.The pins 13 in turn serve to carry coils 14 suspended from them, which in turn are wound on sleeves 15. The free lower ends of the sleeves 15 move along the horizontal movement path 19. A body 32 is provided below the chain 31. This comprises three rollers 33, 34 and a belt 37 rotating in the direction of the arrow 35. As can be seen from FIG. 2, the mutual distance between the chain 31 and the upper run of the belt 37 in FIG. 2 is on the right side the part of the body 32 located on the roller 34 decreasing towards the roller 34.

Im Betrieb der Vorrichtung der Fig. 2 kommen die freien unteren Enden der Hülsen 15 im Bereich abnehmenden Abstandes der sich bewegenden Teile 31 und 37 in Auflage auf das umlaufende Band 36. Bei der Weiterbewegung ergibt sich somit ein Anheben der Hülsen 15, wodurch diese vom Halter 12, bzw. vom Zapfen 13, in der anhand der Fig. 1 beschriebenen Weise frei werden. Die Freigabestelle befindet sich bei dieser Ausführungsform am Ort des Auflaufens der Spulen 14, bzw. Hülsen 15 gegen die Rolle 34. Die freigewordenen Spulen 14 kommen auf der bezüglich der Rolle 34 linken Seite des Körpers 32 auf das Band 37 zu liegen und werden von diesem weiterbefördert, so dass der in der Fig. 2 links der Rolle 34 befindliche Teil des Körpers 32 eine Transporteinrichtung zur Aufnahme und zum Weiterbewegen der Hülsen 15 bzw. Spulen 14 bildet, während der rechts der Rolle 34 befindliche Teil des Körpers 32 einen Auflagekörper zum Freigeben der Hülsen 15 von den Zapfen 13 bildet. Auch dieses Beispiel weist das Merkmal auf, dass der Abstand der Bewegungsbahn der Zapfen 13 vom Auflagekörper 32 in der Richtung gegen die Freigabestelle hin abnehmend ist.2, the free lower ends of the sleeves 15 come into contact with the circumferential belt 36 in the region of decreasing distance between the moving parts 31 and 37. During further movement, the sleeves 15 are thus lifted, causing them to move away from one another Holder 12, or from the pin 13, in the manner described with reference to FIG. 1. In this embodiment, the release point is located at the point where the bobbins 14 or sleeves 15 run against the roller 34. The bobbins 14 that are released come to rest on the belt 37 on the left side of the body 32 with respect to the roller 34 and are thereby removed conveyed so that the part of the body 32 located on the left of the roller 34 in FIG. 2 forms a transport device for receiving and moving the sleeves 15 or coils 14, while the part of the body 32 located on the right of the roller 34 forms a support body for releasing the sleeves 15 of the pin 13 forms. This example also has the feature that the distance of the movement path of the pins 13 from the support body 32 decreases in the direction towards the release point.

Dem Band 37 wird im allgemeinen eine etwas grössere Geschwindigkeit erteilt als der Kette 31. In diesem Fall gelangen an der Freigabestelle die Spulen 14, bzw. Hülsen 15, in die in Fig. 2 gezeigte Positionierung, in welcher beim Umkippen der Spulen 14 sich der Spulenfuss bezüglich der Richtung des Pfeiles 35 vorne befindet.The belt 37 is generally given a somewhat higher speed than the chain 31. In this case, the spools 14 or sleeves 15 arrive at the release point in the position shown in FIG. 2, in which the spools 14 tip over when the spools 14 tip over Coil foot is located in front of the direction of arrow 35.

Der Vollständigkeit halber sei noch erwähnt, dass die gezeigten Bewegungsabläufe und Vorrichtungen mit entsprechenden Aenderungen zum automatischen Aufstecken von Hülsen 15 auf die Halter 12 verwendet werden können. Dies kann z. B. unter Zusammenwirken mit einem Verfahren gemäss der eingangs erwähnten PCT-Veröffentlichung durchgeführt werden.For the sake of completeness, it should also be mentioned that the movement sequences and devices shown with corresponding changes can be used for automatically fitting sleeves 15 onto the holders 12. This can e.g. B. be carried out in cooperation with a method according to the aforementioned PCT publication.
