According to the prior art, an untwisted bundle of yarns formed in the shape of a cheese has been drawn through stationary yarn separatingmeans and separated into individual yarns, andrthe yarns have been passed through a plurality of movable yarn guiding means disposed opposite to a plurality of bobbins and wound on the bobbinsas the yarn guiding means are reciprocally moved along the distance equal to the effective length of the bobbins. But because the yarn separating means is stationary and the yarn guiding means are movable, the length of the yarn running between the yarn separating means and the bobbin always changes with the reciprocal movement of the yarn guiding means, resulting in a change in the tension of the yarn being wound on the bobbin. This phenomenon has been found not only to lower the quality of the yarn wound on a bobbin and put the shape of the bobbin into disorder, but also cause unevenness in a cloth during the weaving or knitting process.
It is, therefore, an object of this invention to provide an improved method of, and apparatus for separating an untwisted bundle of yarns into individual yarns, wherein the above mentioned drawbacks of the prior art are eliminated.
The present invention will be more fully understood from the following detailed description of a preferred embodiment thereof made with reference to the accompanying drawings, in which:
FIG. 1 is a schematic view showing the front elevation of a preferred embodiment of the apparatus according to this invention;
FIG. 2 is a schematic view showing the side elevation of the apparatus shown in FIG. 1; and
FIGS. 3 and 4 are views schematically showing an example of the driving mechanism for the apparatus according to this invention.
Referring first to FIG. 4, a driving device 1 includes a driving bevel gear 3 provided at the end of a main shaft 2 adapted to be rotated by a motor (not shown), and a pair of opposingly disposed driven bevel gears 4 and 4 engaged with the driving bevel gear 3. The driven bevel gears 4 and 4 are loosely mounted on a driven shaft 5, and adapted to be brought into a fixed relation to the shaft 5 by magnetic clutches 6 and 6' respectively when the clutches 6 and 6' attached to the shaft 5 are actuated. The clutches 6 and 6 are so designed that when one of them is in an engaged position with the corresponding driven bevel gear, the other is in a disengaged position. When the clutch 6 is actuated and engaged with the first driven bevel gear 4, the rotation of the driving bevel gear 3 is transmitted to the driven shaft 5 via driven bevel gear 4 to cause the shaft 5 to rotate in a given direction. On the other hand, when the other clutch 6' is actuated and engaged with the second driven bevel gear 4, the rotation of the driving bevel gear 3 is transmitted to the driven shaft 5 via driven bevel gear 4' to cause the driven shaft 5 to rotate in the opposite direction. Shaft 5 provides an appropriate transmitting means for transmitting rotation from the driving device 1 to a pinion 8 (see FIG. 3).
Referring now to FIGS. 1-3, means 9 is provided for separating an untwisted bundle of yarns into individual yarns. As shown in FIG. 3, yarn separating means 9 may include an apertured bar 9A extending diametrically across and affixed at its ends to a ring 913. A plurality of individual yarn guiding means 10 are provided at equal intervals along the circumference of a circle having a center aligned with the center of the means 9. As shown in FIGS. 2 and 3, individual yarn guiding means 10 may include a radially apertured ring 10A. The yarn guiding means 10 are spaced a suitable distance from the yarn separating means 9, and operably associated with the means 9. For example, means 9 and 10 may be associated by means of rods 11A and 11B connecting rings 9B and 10A to form a cylindrical frame. The means 9 and 10 areadapted to be reciprocally moved by a rack 11 formed on rod 11B, and the rack 11 is engaged with the pinion 8. A dog 12 mounted on rod 11A is provided for abutment against limit switches 13 and 13' for actuation of the same. The limit switches 13 and 13 are adapted to govern the actuation of the magnetic clutches 6 and 6' respectively. The same number of bobbins 14 as that of the yarn guiding means 10 are provided close to the means 10 at equal intervals for winding yarns thereon. The bobbins 14 are adapted to be positively rotated, and. the yarn guiding means 10 are reciprocally movable along the effective length of the bobbins 14.
The numeral 15 designates a cheese of untwisted yarns. Yarns 16 are released from the cheese 15, and separated from one another as they are passed through the means 9. Then, the yarns 16 are passed through the yarn guiding means 10, and wound on the bobbins 14. When the dog 12 abuts against the limit switch 13 and consequently the magnetic clutch 6 is actuated and engaged with the driven bevel gear 4, the driven shaft 5 is caused to rotate, and the pinion 8 is caused to rotate as the rotation of the driven shaft 5 is transmitted to the pinion 8, so that the rack 11 engaged with the pinion 8 causes both the means 9 and 10 to move forward. As the means 9 and 10 move forward, the dog 12 reaches the position where it abuts against the other limit switch 13, whereupon the magnetic clutch 6' is actuated and engaged with the driven bevel gear 4' and the driven shaft 5 is caused to rotate in the opposite direction. Thus, the pinion 8 also rotates in the opposite direction, and both the means 9 and 10 are caused via rack 11 to move backward. A forward position of the yarns and means 9 and 10 is shown in solid lines in FIG. 2, a back position thereof being shown in broken lines.
Accordingly, both the yarn separating means 9 and the yarn guiding means 10 repeat reciprocal movement at a constant speed for separating an untwisted bundle of yarns released from the cheese 15 and winding them on the bobbins 14. As shown in FIG. 2, the cheese 15, which provides a source of untwisted bundled yarn, is disposed to one side of the path of reciprocation of the yarn separating means 9, lying in a plane perpendicular to the path of reciprocation of the yarn separating means cutting said path near to the yarn separating means, whereby as the yarn separating means reciprocates the distance from the yarn separating means to the source of untwisted bundled yarn remains substantially constant. Specifically, as shown in FIG. 2, the mean position of the yarn bundle betweensource l5 and separating means 9 is perpendicular to the axis passing through separating means 9 and the center of the circular array of traverse guide means 10. Therefore, the length of the yarns running between the separating means 9 and the bobbins 14 is kept constant, so that no change can occur to the tension of the yarns being wound on the bobbins.
It will be apparent from'the foregoing description that this invention provides a markedly improved method and apparatus for yarn separation in which an untwisted bundle of yarns is separated into individual yarns, guided and wound on bobbins as both the yarn separating and guiding means are reciprocally moved at a uniform speed, whereby the length of yarns running between the yarn separating means and the bobbins is kept constant and any change in the tension of the yarns being wound on the bobbins is prevented. Thus, this invention provides a very effective solution to any problems that have been encountered in the process of yarn separation according to the prior art in which variation in the tension of the yarns being wound on bobbins has been unavoidable.
