Definitions

  • This novel yarn transfer method consists of the steps of driving said first and second bobbins with independent electric motors, lowering a traverse speed of the yarn to a speed that is most suitable for formation of a transfer tail, displacing a traverse cam roll with a pneumatic cylinder or other known means so as to make the yarn contact with a yarn grasping device provided at an end of the bobbins or on a bobbin holder and to make the yarn grasping device grasp said yarn, cutting off the yarn between said yarn grasping device and the fully wound first take-up bobbin by means of a cutter associated with said yarn grasping device to take-up the yarn on the second unwound bobbin, restoring the traverse cam roll to its normal position simultaneously with the formation of the transfer tail, accelerating the traverse speed up to a speed upon normal take-up operation, pressing the unwound second bobbin against
  • This invention relates in general to improvements in an automatic take-up motion, and more particularly to improvement in a method of automatically transferring a yarn from a first bobbin on which said yarn has been being taken-upto a second unwound bobbin on which said yarn is to be wound subsequently in said automatic take-up motion.
  • the formation of the transfer tail was possible according to the method of transferring a yarn in which after the yarn has been taken-up on a fully wound bobbin the yarn is disengaged from a traverse guide and then the yarn is engaged to a yarn grasping device provided at an end of an unwound bobbin or on a bobbin holder, there was a fear that a yarn may be taken-up on the fully wound bobbin without being traversed and thus a fully wound package may possibly get out of shape upon high speed taken-up operation, because the yarn was disengaged from the traverse guide.
  • the present invention has been worked out in order to obviate the aforementioned disadvantages in the prior art, and it is a principal object of the present invention to provide a novel yarn transfer method in an automatic take-up motion, in which a transfer tail can be formed and also transfer of a yarn can be achieved reliably by continuing traverse of the yarn without disengaging the yam from a traverse guide and by carrying out transfer of the yarn while it is being taken-up on a fully wound bobbin.

  • Numeral 6 designates a pneumatic cylinder (having a stroke of about mm) for displacing the traverse cam roll 2 and is coupled to the bearing 4.
  • Numeral 7 designates an electric motor for driving the traverse cam roll 2, which is telescopically coupled to the traverse cam roll 2 through a coupling mechanism 8.
  • Numeral 9 designates another electric motor for the drive roll 1. It is to be noted that the aforementioned drive roll 1 is adapted to be pressed against a bobbin by any appropriate butting means (not shown).
  • Reference numerals 10, 10 designate bobbin,
  • Numerals 12, 12 designate electric motors for accelerating the bobbins, which are contained within the bobbin holders l0 and 10, respectively, and which are connected to an external power supply (not shown) through wires 13 and slip rings 14.
  • Numeral 15 designates an unwound bobbin
  • numeral 15 designates a fully wound bobbin
  • numerals l6 and 16' designate yarn grasping devices provided on the respective bobbins l5 and 15.
  • Numeral l7 designates yarns at the opposite traverse end positions during the period when the yarn is traversed in a normal take-up operation
  • numeral 18 designates yarns at the opposite traverse end positions during the period when the traverse cam roll 2 has been displaced by actuating the pneumatic cylinder 6 so that the yarn may contact with the yarn grasping device 16, numeral 19 v 15 has become fully wound, the electric motor 12 contained within the bobbin holder for the unwound.
  • the bobbin is automatically switched on to accelerate the unwound bobbin 15 until it acquires such r.p.m. that its peripheral velocity becomes equal to or higher than the linear velocity of the yarn that is being wound on the fully woundbobbin 15' (FIG. 2). Subsequently, after the rpm. of the unwound bobbin has been completely raised, the turret arm 11 is rotated to separate the fully wound bobbin 15 from the drive roll 1 and to bring the unwound bobbin 15 to a position just in front of the position where it contacts with the drive roll 1 (FIG. 3).
  • the traverse speed control device 19 is actuated to lower the traverse speed to a speed most suitable for formation of a transfer tail (30 100 rpm). Since the fully wound bobbin 15 becomes not to be applied with a driving force as it leaves the drive roll 1 at this moment, in order to prevent the yarn from slackening the electric motor 12 contained within the bobbin holder 10 for the fully wound bobbin 15 is switched on simultaneously with the rotation of the turret arm 11 and thereby a tension in the yarn can be maintained.
  • the yarn is taken-up on the fully wound bobbin l5" and traversed at a reduced traverse speed, while it is slipping on the surface of the unwound bobbin 15 that is being rotated at a high speed.
  • the pneumatic cylinder 6 is actuated to displace the traverse cam roll 2 by about mm so that the traverse motion may be performed up to the position where the yarn makes contact withthe yarn grasping device 16 provided at one end of the bobbin. In this way, the yarn l8 traversed up to the position above the yarn grasping device 16 is at once en-.
  • the commencement of the take-up operation is detected by means of the photoelectric tube means 20, and in response to the detected signal, the pneumatic cylinder 6 is again actuated to restore the traverse cam roll 2 to its normal position, the traverse speed control device 19 is actuated to realize a normal traverse speed, the unwound bobbin 15 is pressed against the drive roll 1, and simultaneously therewith the electric motors 12 and 12 contained within the respective bobbin holders 10 and 10 are switched off.
  • the unwound bobbin 15 is frictionally driven by the drive roll I to achieve the conventional surface drive type of take-up operation.

  • a speed control sys U tem is employed, in which inverter power supplies for high speed operation and for low speed operation are I individually provided and upon yarn transfer-these, power supplies are switched from one to another to achieve speed control.
  • the unwound bobbin is made to contact with the yarn that is being taken-up on a fully wound bobbin, then the yarn travelling towards the fully wound bobbin is transferred to the unwound bobbin by actuation of a yarn grasping device at an end vice provided at an end of the bobbin or on the bobbin f holder, to thereby achieved yarn grasping and cutting a of the yarn. Since the yarn is being traversed at a reduced speed, it is taken-up in a spiral form having a small pitch angle from the end of the bobbin towards its central portion to form a transfer .tail. This commencement of the take-up operation is detected by means of a photoelectric tube or other known means,
  • the traverse means is restored to the position upon normal take-up operation and also the traverse frequency is also restored to the frequency upon normal take-up operai tion. ln addition, simultaneously with the commencement of take-up operation of the yarn, the power supply for the accelerating electric motor is switched off, and the take-up operation is achieved according to a.
  • the yarn transfer operation can be carried out in a reliable manner.
  • a transfer tail can be formed simultaneously with the winding of the yarn itself round the bobbin, and by restoring the traverse means to the position for normal take-up operation after the formation of the transfer tail has been confirmed, the yarn wound not be taken-up as overlapped on the initially formed transfer tail, and so a perfect transfer tail can be obtained.
  • the fully wound bobbin is rotating due to its own inertia, as it is separated from and not driven by the drive roll.
