Definitions

  • the present invention relates to an unwinding tension applying device for applying a predetermined unwinding tension to yarn when the yarn is unwound axially from a package (so-called a yarn supply pakage) formed by winding the yarn in a predetermind shape.
  • yarn is wound round a bobbin into a predetermined shape and is handled as a package.
  • an endless cloth-like friction member F As an unwinding tension applying device used for such purpose it is known to use an endless cloth-like friction member F, as shown in Fig. 9.
  • a package P is mounted substantially horizontally on a creel frame (not shown) through a spindle SP, and sideways of the package P there is disposed a fixed rod RD in parallel with an axis Pc of the package P.
  • a fixed rod RD Inside the friction member F is inserted the package F so that the friction member is entrained about the package.
  • An intermediate part of the friction member F is passed round the fixed rod RD, and a weight W is inserted into an opposite end side of the friction member which side is hanging down.
  • a tension according to the weight of the weight W is created in the friction member F, which in turn exerts a pushing force against the outer peripheral surface of the package P, so that a predetermined unwinding tension can be applied to the yarn Y being unwound from the surface of the package. This is because the yarn Y is drawn out in the direction of the axis Pc while being sandwiched in between the package P and the friction member F.
  • FIG. 1 there is illustrated an unwinding tension applying device for a package according to a typical embodiment of the present invention.
  • This unwinding tension applying device includes a pair of friction members 11, 11 disposed in a suspended fashion on both sides of a package 1, and operating members 21, 21, 22, 22 which are disposed exteriorly on both sides of the friction members.
  • the package 1 is formed by winding yarn in a predetermined winding shape around a bobbin 1 a.
  • Its winding shape is usually a parallel cheese shape having parallel both ends as shown in Fig. 2-(A), or it may have a tapered portion 1 b at one end thereof as shown in Fig. 2(B), or it may have tapered portions 1 b, 1 at both ends.
  • a spindle 2a is projecting substantially horizontally from a creel frame 2, and the bobbin 1 a of the package 1 is fitted on the spindle 2a, whereby the package 1 is mounted substantially horizontally on the creel frame 2.
  • the friction members 11, 11 are each constituted by a band-like member having a predetermined width d so as to cover at least an end portion on a yarn Y draw-out side of the package 1, with their upper ends being fixed to the creel frame 2. Weights 11 a, 11 a are connected to the lower ends of the friction members 11, 11. It is here assumed that the spacing D between the friction members 11, 11 in a naturally suspended state is larger than a maximum diameter of the package 1.
  • the friction members 11, 11 are each constituted by a sheet-like member such as, for example, cloth, plastic sheet, or rubber sheet, and can bend freely.
  • the operating members 21, 21, 22, 22 are disposed outside the friction members 11, 11 and above and below the package 1, each in parallel with an axis 1 of the package 1.
  • the operating members 21, 21, 22, 22 are each constituted by a rod which is longer than the width d of each friction member 11.
  • Each pair of such operating members located on both sides of the friction members 11, 11 move toward each other and assume operating positions (indicated by dash-double dot lines in Fig. 1) and can also move away from each other and assume retracted positions (indicated by solid lines in Fig. 1).
  • a friction member 11 is disposed on only one side and as an operating member corresponding thereto there is disposed only a lower operating member 22.
  • the operating member 22 is fixed to a front end of a downwardly curved rocking arm 22a, which arm is constructed to pivot about a shaft 22b.
  • the rocking arm 22a is moved pivotally in the direction of arrow in the same figure, the operating member 22 moves to an operating position 22', whereby the friction member 11 can be contacted with about a lower half of the peripheral surface of the package 1.
  • a friction member 11 (see Fig. 6) also on the other side with respect to the package 1.
  • the friction member 11 on the other side can be contacted with the package 1 from above by means of an operating member 21 which can largely move obliquely downwards.
  • an auxiliary operating member 23 is disposed for the friction member 11 in question.
  • the auxiliary operating member 23 slightly moves horizontally in synchronism with the operating member 21 to avoid mechanical interference with the friction member 11 associated with the operating member 22. It is desirable to constitute the auxiliary operating member 23 so that it moves back to its retracted position together with the operating member 21, thereby separating the friction member 11 farther from the package 1.
  • FIG. 7 there is illustrated a further embodiment of the present invention, in which friction members 11 opposed to each other can be brought into contact with all of plural packages 1, 1 which are arranged vertically in parallel.
  • upper ends of the friction members 11, 11 are connected to auxiliary operating members 24, 24 which can move horizontally in synchronism with operating members 21, 21, 22, 22, and lower ends of the friction members 11, 11 are interconnected while carrying a common weight 11 a thereon.
  • the friction members 11, 11 are pressed at three points - upper, middle and lower points - with respect to the packages 1, 1 by the auxiliary operating members 24, 24 and the operating members 21, 21, 22, 22, whereby the frictions members can be contacted with the packages simultaneously.
  • packages 1, 1 arranged vertically in parallel can be increased optionally.
  • packages 1, 1, ... may be arranged in plural parallel rows, and the auxiliary operating members 24, 24 and the operating members 21, 21, 22, 22 for each those rows may be driven between their operating positions and retracted positions simultaneously by means of a common driving mechanism.
  • friction members 11, 11 are contacted in common with plural packages 1, 1, ... which are arranged laterally side by side.
  • Operating members 21, 21, 22, 22, ... are disposed on both right and left sides of the packages 1, 1, ... and also in intermediate positions between adjacent packages in a vertically sandwiching relation to the friction members 11, 11.
  • One ends of the friction members 11, 11 are fixed to a creel frame 2, while the other ends thereof are allowed to hang down and then connected together, with a weight 11 a carried thereon.
  • connection between the friction members 11, 11 may be rendered disengageable using such a connecting member as a zipper for example. This is convenient for changing the weight 11 a to adjust the tension to be applied to the friction members 11, 11.
  • each friction member 11 may be almost equal to or somewhat longer than the overall length of the package 1. Or the width d of the friction member 11 may be made extremely small into a thick string not permitting the engagement of the yarn Y therewith. Further, since the weight 11 a is for applying an appropriate tension to the friction member 11, it may be substituted by a suitable spring member.
  • friction members capable of being bent and operating members for bending the friction members into contact with a package are combined together, whereby upon movement of the operating members to their operating positions, an unwinding tension can be applied to yarn through the friction members, while upon movement of the operating members to their retracted positions, the friction members can be moved out of contact with the package.
  • package replacement therefore, it is not necessary to pass the friction members round the package and disengage them from the package, whereby the working efficiency can be greatly improved. Further, the package replacement and a series of creel operations associated therewith can be automated easily.
  • the present invention relates to an unwinding tension applying device for applying tension to yarn being unwound from a package formed by winding of the yarn thereon.
  • this unwinding tension applying device friction members on which is exerted the gravity of weight or the tenseness of spring member are brought into contact with the outer periphery of the package by moving operating members close the package, whereby not only the occurrence of kinky thread (snarl) and the entanglement of yarn can be prevented, but also since the operating members and the friction members can be moved away from the package, it is possible to effect the package replacement easily.
