Schußspulenauswechselvorrichtung für Webstühle.Weft bobbin changing device for looms.

Patentiert im Deutschen Reiche vom 29. Juni 1906 ab.Patented in the German Empire on June 29, 1906.

. Vorliegende Erfindung betrifft die Art von Schußspulenauswechselvorrichtungen für Webstühle, bei welchen im Falle eines Schuß-. fadenbruches eine Ersatzspule bei Anschlag des Stuhles in den Schützen ein- und die verbrauchte Spule hinausgeschoben wird.. The present invention relates to the type of weft bobbin changing devices for looms, in which in the event of a weft. thread break a spare bobbin when the chair hits the shooter and the used bobbin is pushed out.

Die Erfindung besteht in der eigenartigen Anordnung des die Ersatzspulen enthaltenden Behälters.The invention consists in the peculiar arrangement of the one containing the replacement coils Container.

ίο Die Neuerung besteht darin, daß die Spulenhalter unabhängig oder unverbunden miteinander angeordnet sind, einzeln eingelegt und bei Beschädigung leicht herausgenommen und durch andere ersetzt werden können.ίο The innovation is that the bobbin holder are arranged independently or unconnected to each other, individually inserted and if damaged, they can easily be removed and replaced with others.

Auf den Zeichnungen ist die Anwendung des neuen Spulenbehälters bei einer Auswechselvorrichtung beispielsweise dargestellt, bei welcher die Ersatzkötzerspindeln in einen Greifer eingeschoben werden, der bei Schußfadenbruch aus seiner senkrechten in eine horizontale Lage gedreht wird, und beim Anschlag der Lade die Ersatzspule in den Schützen von vorn ein- und die verbrauchte Spule ausschiebt. Die Anwendung der Erfindung ist auf diese Art von Auswechsel-. vorrichtung nicht zu beschränken.The drawings show the application of the new bobbin case to a replacement device for example shown, in which the replacement Kötzerspindeln are inserted into a gripper, which in the event of a weft thread breakage is rotated from its vertical to a horizontal position, and when the drawer stops, the spare reel is in the Protect from the front and push out the used bobbin. Application of the invention is on this type of substitute. device not to be restricted.

Fig. ι ist eine Seitenansicht des Behälters von der Außenseite und Fig. 2 eine Seitenansicht von der Innenseite des Webstuhles, Fig. 3 eine Vorderansicht des Behälters, Fig. 4 ein Spulenträger in verschiedenen Ansichten; Fig. 5 zeigt den Greifer.Fig. 1 is a side view of the container from the outside and Fig. 2 is a side view from the inside of the loom, FIG. 3 is a front view of the container, FIG. 4 a coil carrier in different views; Fig. 5 shows the gripper.

Bei der Auswechselvorrichtung werden die Spulen 1 in bekannter Weise von den Spindein 2 getragen, die mit dem einen Ende in rechteckigen Köpfen 3 befestigt sind.In the case of the replacement device, the reels 1 are removed from the spindles in a known manner 2, which are fastened at one end in rectangular heads 3.

In dem Behälter werden diese Spindeln einzeln in Haltern getragen und verschoben, welche auf Schienen 4. (Fig. 3) befestigt sind und aus je einem' federnden Backenpaar 5 für den Kopf 3, einem eingekerbten Träger 6 für die Spitze der Spindel und einem Stift oder Haken 7 zur Befestigung" des Fadenendes bestehen. Die Enden der Schienen 4 sind mit Stiften oder Zinken 8 versehen, die in gekrümmten Nuten gleiten können, zweckmäßig rund sind und mit Rollen versehen werden können. Der Behälter wird durch die beiden Seitenwände 9, 10 gebildet, die an den einander zugekehrten Seiten mit umlaufenden Nuten 11 versehen sind, in die die Zinken 8 der nebeneinander liegenden Schienen 4 eingreifen und derart gleiten können, daß die nebeneinander gereihten Schienen 4 · eine umlaufende Transportfläche bilden. Die Stifte 8 greifen hierbei nur so weit in die Nuten 11 der Seitenwände 9, 10 ein, daß an den Schienen 4 noch genügend Raum für das Eingreifen der sie fortschiebenden Stifträder 21 verbleibt. Die Seitenwände werden zweckmäßig aus dem rechteckigen Mittel- , stück 13 und den dieses abrundenden Endstücken 12 gebildet, welche mit dem Mittelstück durch Flanschen 14 und Bolzen 15 zusammengefügt sind. Jede Seitenwand ist mit einem Fuß 16 versehen, der zum Anbolzen auf die an der Stuhlseite befestigte Tragplatte 17 dient.In the container, these spindles are carried and moved individually in holders, which are fastened on rails 4. (Fig. 3) and each consist of a pair of resilient jaws 5 for the head 3, a notched support 6 for the tip of the spindle and a pin or hooks 7 for fastening "the thread end. The ends of the rails 4 are provided with pins or prongs 8 which can slide in curved grooves, are suitably round and provided with rollers can be. The container is formed by the two side walls 9, 10 that are attached to the mutually facing sides are provided with circumferential grooves 11 into which the Tines 8 of the rails 4 lying next to one another engage and slide in such a way that that the rails 4, which are lined up next to one another, form a circumferential transport surface. the Pins 8 only engage so far into the grooves 11 of the side walls 9, 10 that the rails 4 still have enough space for the engagement of the pin wheels pushing them away 21 remains. The side walls are expediently made of the rectangular central, piece 13 and this rounded end pieces 12 formed, which with the middle piece are joined together by flanges 14 and bolts 15. Every sidewall is provided with a foot 16 which is attached to the side of the chair for bolting Support plate 17 is used.

Die beiden Seitenwände 9, 10 tragen die in Büchsen 19 ruhende Welle 20, auf weleher die Stifträder 21 befestigt sind, deren Zähne so geformt sind und eine solche Tei-The two side walls 9, 10 carry the shaft 20 resting in bushes 19, on which the pin wheels 21 are attached, the teeth of which are shaped and such a part

Claims

ment have that they can engage between the prongs 8 of the rails 4. Outside of of the walls 9, 10 is on one end of the shaft 20 carrying the wheels 21 the gear 24 cooperating with the ratchet tooth 23 and on the other side the wave-shaped fluted disk 22 is attached. The angular position of the groove is the same as that of the teeth of the pin wheels 21, and in the groove of the Disc 22 is an escapement spring.

At the ends of the side walls 9, 10 tabs 25, 26 are also provided in which the shaft 27 is mounted. This shaft carries a plate with grippers for receiving the Spool from the container, which in the event of a thread breakage from the vertical to the horizontal Position are rotated and bring the coil in the path of the shooter, so that when Stop of the drawer, the used bobbin pushed out by the spare bobbin and the spare bobbin is withheld in the shooter when the drawer falls.

The spool carriers are advanced by one pitch after each replacement and thereby insert a replacement spool into the grippers on shaft 27.

These grippers consist of the one attached to shaft 27 in a known arrangement Bearing block 28 (Fig. 5), in one arm of which is arranged at the outer end of the spindle head Projection 29, and in the other arm of which the coil itself rests, a spring pressing against the head to keep it in the correct position.

In case of breakage or absence of the weft yarn in a known manner, a device in operation is set that 28 to 90 ⁰ rotates the shaft 27 is seated on the arms and thereby brings the gripper in its horizontal position. In order to rotate or advance the pin wheels 21 and the rails 4 by one pitch after each replacement, the ratchet wheel 24 provided with the corresponding pitch is rotated by one tooth by the three-armed angle lever 30, 31, 32. This angle lever sits loosely on the shaft 20, and its arm 30 carries the switching pawl 23 which engages in the ratchet wheel 24.

· When the rod 29 ^{1 is} raised, its upper end strikes against the second arm 31 of the angle lever and rotates it backwards. The third arm 32 of the angle lever supports a pin 34 fastened to the rail 33 in an elongated hole, while the rail itself engages with an elongated hole via a pin 35 which is fastened to the tab 36.

If the angle lever is rotated as described, its arm 32 pushes the rail 33 forward, and at the same time it lifts a projection 37 of the rod 29 'so that the rail 33 passes through a slot in the plate attached to the drawer and the drawer strikes when changing without moving the rail.

Before the next stop, the rod 29 'is pulled down and the rail 33 in the Has fallen back in the position in which it is hit by the plate when the drawer hits it, thereby turning the angle lever forward, so that the pawl moves the ratchet wheel and the rails 4 by one pitch, one brings new spare set reel in front of the gripper, which is now in its vertical position has returned and the device is ready for the next replacement: If one of the rails 4 is damaged, the adjacent ones are seldom disturbed, and can remove the damaged rail after removing the upper end pieces 12 of the container wall easily removed and replaced with another. Furthermore, the number of rails becomes twice that number If the pins of the feed wheels 21 are made, the same pins of the wheels always come engaged with the same two rails.

Patent-A ν saying:

Weft bobbin changing device for looms, characterized in that each weft reel is arranged on a rail (4), which jaws (5) for the spindle head, a fork (6) for the Has a spindle tip and a pin for tying up the weft thread and is provided with pins (8) at each end, which are guided in endless grooves in the fixed container walls (9, 10) and at the same time for the engagement of the pin wheels to switch the rails after each reel change to serve.
