Graham, Anniston, Ala., assignor to Adelaide Mills, Anniston, Ala., a corporation of Alabama Filed Mar. 4, 1969, Ser. No. 12,730 7 Claims. (Cl. 28-19) This invention relates to a centrifriction bobbin cleaner. It has for its main object to provide a machine to remove roving quickly from bobbins regardless of how many layers are left on them. In block creeling it is not possible to make the roving run olf all together. Some may have one layer or less and others may have ten or fifteen layers.
Further objects are to provide such a machine that will be highly satisfactory for the purpose intended, simple in structure, comparatively cheap to manufacture, easy to keep in working condition, and very durable.
Other objects and advantages will appear from the By referring generally to the drawings it will be observed that:
ing motor and other parts.
FIG. 7 shows the wiring and switch connections.
Similar reference numerals refer to similar parts throughout the several views.
Referring to the drawings in detail it will be seen that the machine comprises a main supporting frame I having a trough formed by one side 2 held in fixed condition on the frame with its other side 3 mounted swingably on the opposite side of the frame by means of ear portions 3' formed thereon to engage the frame as seen in FIG. 5. A metal roller 4 is supported by its ends 5 and 6 in bearings 7 and 8 and is revolved by a pulley 9, carried at the roller end 5 beyond the bearing 7, through a belt 10 leading to a pulley 11 of a drive motor 12. A second metal roller 13 is mounted by its ends 14 and 15 in bearings 16 and 17 that are supported slidably by spring means 18 adapted to press this second roller 13 for its entire length against the first roller 4. The second roller 13 is encased in rubber cots or sections 19 and, being pressed in contact tightly with the adjacent face of the other roller 4, revolves as a result of friction contact when the other roller 4 is driven. There are microswitches 2t} and 21 at the ends of the machine near the rubber covered roller 13 adapted to disconnect power from the motor 12, and thus stop the machine, if a choke occurs anywhere on the rollers 4 and 13 that tends to force them apart. The roilers 4 and 13 are suitably made of steel tubing and may be of any suitable diameter and length, but ZMt-inch diameter for the driving roller 4, 2-inch diameter for the driven roller 13, with seven sections of rubber 12 inches long, 2 inches inside diameter, and 2 /2 inches outside diameter would be highly satisfactory. A toggle switch 22 is in the supply wires 23.
In operation bobbins 24 are cleaned by being rotated at high speed in a direction to unwind the roving. This causes the roving to tend to sling off. The loose end is acted on by the centrifugal force and in turn caught between the metal roller 4 and the rubber covered roller 13 and pulled off. The roving passes through the rollers 4 and 13 with enough speed to sling it down and away from the rollers thus preventing it from lapping around the rollers; as each of these rollers 4 and 13 necessarily operates at a surface speed comparable to that at which the bobbins 24 are rotated and is of a diametric size, suitably as noted above, that is restricted so as to cause roving passing therethrough to be thrown free centrifugally from the roller surfaces. The machine is sufficiently high and wide to accommodate wheeled waste boxes beneath it to catch the roving taken off. The bobbins 24 to be cleaned are placed in the trough of the machine on the rollers 4 and 13 by hand one at a time until there are six in the machine. Being placed one at a time the first bobbin 24 must travel the entire length of the rollers 4 and 13 one bobbins length at a time as each successive bobbin is placed on the rollers. After the machine is full, as each additional bobbin 24 is placed in the machine to be cleaned, a cleaned one is forced ofi at the other end of the machine and falls into a box placed for this purpose.
The machine may be made of any material suitable for the purpose, but I prefer to use good grades of metal, rubber, and electrical equipment. Also it may be made in different sizes and capacities.
While I have shown and described the preferred embodiment of my invention, I do not wish to limit same to the exact and precise details of structure, and I reserve the right to make all modifications and changes so long as they remain within the scope of the invention and the following claims.
Having described my invention I claim:
