Description

United States Patent "ice COLLECTOR FOR YARN BOBBINS Walter Schweiter, Horgen, Switzerland, assignor to Maschinenfabrik Schweiter A. G., Horgen, Switzerland, :1 Swiss company The present invention relates to a collector device for yarn bobbins.

In the case of known collectors of this type the bobbins ejected from the winding frame fall from above into the collector, whereby the yarn coils are often damaged owing to the fact that the bobbins fall on top of one another.

The present invention has as one of its objects to provide means aifording elimination of this drawback. The invention therefore contemplates means disposed at the lower part of the collector or its bottom constituting a bobbin filling hole which closes automatically. In this way the number of bobbins in the collector can be easily ascertained and the bobbins can be taken out of the said collector from the side. The collectors can be secured to a loom so that the weaver can remove the bobbins from the collector, when filled, and charge the drum magazine of an automatic loom,

A typical example of the invention is illustrated in the attached drawing. In the drawing:

Fig. 1 shows the collector seen from the open side;

Fig. 2 is a side view of Fig. 1;

Fig. 3 is a top view of Fig. 1;

Fig. 4 is a fragmentary section, on an enlarged scale, through a portion of the bottom of the collector along the line II in Fig. 3;

Fig. 5 is a view of the shut-off fiaps along the line IL-II in Fig. 4;

Fig. 6 is an alternative example of the invention in whichthe bobbin filling hole is arranged above the bottom plate in a side wall.

The collector consists of three

perpendicular side walls

1, 2 and 3, a top 4 and a bottom plate or wall 5, together defining an open space for storage of bobbins. To the bottom plate 5 is secured an upwardly directed sheet metal stirrup or arcuate guide 8 which possesses cut-out portions 8a. A pivot forming rod 9 is enveloped by the remaining free sheet metal ends 8b and secured with a cotter pin. Tongues 10a of a stop plate 10, which tongues are also rolled about rod or pivot 9 and secured to the said rod with a pin, engage into the cut-out portions 8a. The stirrup 8 and the stop plate 10 can also be made from one piece. Furthermore, the stirrup 8 possesses cut-out portions 80 in which shut-off flaps 12 engage which are swivelly located on the rod 9. These shut-off flaps possess a recess 13 in which a torsion spring 14 is located on the rod 9. One end of the said spring thrusts against the wall 12a of the shut-off flap 12' and the other against the stop plate 10. The shut-off flaps 12 are pressed by these torsion springs into the position illustrated in Fig. 4. Adjacent to the opening or aperture 5a in the bottom plate 5 there is a perpendicular web 7 which is bent over y, 2,873,063 Patented Feb. 10, 1959 from falling out by the shut-off flap 12 which at least partly obstructs aperture 5a.

It will be noted that the stirrup 8, the web 7 and the flaps 12, at their portions facing toward the storage space, form object deflecting means, i. e. means which facilitate the removal of bobbins out of the feeding path and into the storage space. Moreover, they prevent that an object fed along said path jams the flaps 12 in closed position thereof by preventing said object from contacting the upper or inner side of walls 12a of the flaps 12. The defleeting means, provided by the stirrup 8 and the web 7 extend into the storage space laterally of said guide channel.

The hole through which the bobbins pass into the collector is arranged at right angles to the rear wall 3 so that the number of bobbins in the collector can be seen from the front and the bobbins can be easily taken out of the collector. The bobbin collector is conveniently provided with two

handles

17 and 18 one of which is arranged in the extension of the bottom plate 5 on the open side of the collector and the other on the collector at its top and, for the purpose of stiffening it, is secured top 4. Owing to this arrangement of the handles the bobbins lie up against the rear wall of the collector so that the latter cannot be carried in such a way that the bobbins fall out, since the open side of the collector always faces upwards. The collector top 4 is, in addition, provided with an opening 19 which is designed for the purpose of enabling a feeler from the winding frame to penetrate into the box, which feeler stops the delivery of bobbins when the box is full.

As Fig. 6 shows, the bobbins, in an alternative arrangement, can also be fed into the collector immediately above the bottom plate through an opening in a side wall 20!, inside which shut-off flaps 12b are arranged. The bobbins 15 can be pressed into the collector by a swivel arm 16. This arrangement can be used when it is impossible, owing to lack of space, to charge the bobbins through the bottom plate.

Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes andmodifications be embraced by the annexed claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

l. A collector device for bobbins comprising a pair of spaced parallel side walls, a further side wall extending between said pair of side walls, a top wall on said side walls, a bottom wall on said side walls and provided with an aperture extending in substantially parallel direction to said pair of side walls, said top wall, bottom wall and said side walls defining a container having an opening extending between said bottom wall and said top wall for receiving and affording access to said bobbins, arcuate guide means on said bottom wall and adjacent said aperture, pivot means operatively connected with said guide means and disposed longitudinally of said aperture, flap means mounted about said pivot means for swinging movement relative to said guide means, and spring means arranged to normally urge said flap means into a position at least partially obstructing said aperture, whereby a bobbin may be inserted into said container by swinging said flap means about said pivot means against the action of said spring means, said flap means thereafter automatically returning to said obstructing position by said spring means for retention of said inserted bobbin in said container, in which said bobbin is accessible from without said container at said opening.

2. In a collector device having side walls and a bottom wall defining a storage space for objects and having an opening in one of said walls for feeding said objects into said storage space; displaceable flap means located adjacent said opening and arranged for movement relative to the latter to at least partially obstruct the same in closed position of said flap means, guide channel means extending interiorly of said storage space from said one wall thereinto, said channel means being arranged to terminate in said opening, and object deflecting means adjacent said guide channel means and-extending laterally thereof into said storage space, said guide channel means defining a path of feed for said objects through said opening into said storage space, said flap means projecting into said path intermediate said opening and said storage space, and said object deflecting means being so constructed as to remove an object fed along said path away from said flap means into said storage space upon feeding of another object along said path, and to permit free displacement of said flap means from said closed position for passage of said other object into said storage space subsequently to the removal of said one object from said path.

3.
