In this case, the yarn wound around the drum is loosened, and the yarn wound around the drum may bulge out to an outer side of the drum. When such a phenomenon occurs, the operator needs to carry out the task of removing the yarn from the drum.
- a yarn winding device with a tension measuring device adapted to measure a tension of the yarn pulled out from the yarn storage roller by the package forming section and a control section adapted to feedback control the second driving section based on a measurement result of the tension measuring device to adjust an amount of tension applied to the tension applying section is known.

- the control section is adapted to feedback control the second driving section based on a measurement result of the tension measuring device to adjust an amount of tension applied by the tension applying section.
- the tension on the downstream of the yarn storage roller is measured and the second driving section is controlled based on such a measurement result, and hence a desired tension can be applied to the yarn to be wound into the package.

- the gate type tension applying device 12 of the present embodiment is configured as a gate type in which movable comb teeth are arranged with respect to fixed comb teeth.
- the comb teeth on the movable side are configured to be swingable by a rotary solenoid so that the comb teeth can be in the meshed state or the released state.
- the configuration of the gate type tension applying device 12 is not limited thereto, and may be a disc type tension applying device, for example.
- the upper yarn catching section 13 is arranged between the yarn joining device 14 and the bobbin supporting section 7.
- the upper yarn catching section 13 is connected to a negative pressure source (not illustrated), and can generate a suction airflow during the yarn joining operation.
- the yarn trap 15 is arranged between the yarn joining device 14 and the yarn storage device 18.
- the distal end of the yarn trap 15 is formed as a tubular member and is arranged close to the travelling path of the yarn 20, and is connected to the negative pressure source (not illustrated). According to such a configuration, the suction airflow can be generated at the distal end of the yarn trap 15 to suck and remove contaminants such as fluffs attached to the travelling yarn 20.
- the clearer 17 is configured to detect the yarn defect such as slub by monitoring a yarn thickness of the yarn 20.

A cutter 16 for immediately cutting the yarn 20 according to the disconnecting signal is arranged in proximity to the clearer 17.
- the yarn joining device 14 joins the lower yarn from the yarn supplying bobbin 21, and the upper yarn from the yarn storage device 18, when the yarn 20 between the yarn supplying bobbin 21 and the package 30 is in the disconnected state after yarn breakage in which the clearer 17 detects the yarn defect and the cutter 16 cuts the yarn 20, after yarn breakage during unwinding of the yarn 20 from the yarn supplying bobbin 21, or at the time of replacing the yarn supplying bobbin 21.
- the yarn joining device 14 may be a type that uses a fluid such as compressed air, or may be a mechanical type.
- the upper yarn pull-out section 35 is an air sucker device, and pulls out the upper yarn from the yarn storage device 18 and feeds the upper yarn towards a deflection guide member 36.

- the deflection guide member 36 discharges the fed upper yarn from the lower end portion.
- the yarn discharged by the deflection guide member 36 is sucked by the upper yarn catching section 13.
- the upper yarn can be taken out from a slit (not illustrated) formed in the deflection guide member 36 as the upper yarn catching section 13 sucks the upper yarn, so that the upper yarn can be guided to the yarn joining device 14.
- the lower yarn fed by the lower yarn blow-up section 11 is sucked by the yarn trap 15.
- the lower yarn is thereby guided to the yarn joining device 14.
- the yarn joining operation is carried out in such a manner.
- the yarn defect is removed mainly by the clearer 17, the upper yarn catching section 13, the yarn trap 15, and the yarn joining device 14, and hence such devices correspond to "yarn defect removing device".
- the yarn storage device 18 is configured to be able to temporarily store the yarn 20 unwound from the yarn supplying bobbin 21. Since the yarn storage device 18 is interposed between the bobbin supporting section 7 and the winding section 8, and a prescribed amount of the yarn 20 is stored on the yarn storage device 18, the winding section 8 can wind the yarn 20 stored on the yarn storage device 18 even if the unwinding of the yarn from the yarn supplying bobbin 21 is interrupted (e.g., during yarn joining operation) for some reason. Thus, the winding of the yarn 20 into the package 30 can be continued.
- the package 30 can be produced stably at high speed. Furthermore, since the yarn 20 is not sucked and caught from the package 30 for each yarn joining operation as in the conventional yarn winding device, disturbance can be prevented from occurring at the surface of the package 30. Moreover, since the occurrence of yarn breakage in the winding section 8 is reduced, falling of the yarn 20 onto the end face of the package 30 or occurrence of a failure in the winding shape can be prevented.
- a first guide section 41, a second guide section 42, and a tension measuring device 43 are arranged on the downstream of the yarn storage device 18.
- the first guide section 41 converges the yarn 20 pulled out from the yarn storage device 18 so as to guide the yarn 20 to one area.
- the second guide section 42 is arranged downstream of the first guide section 41.
- the second guide section 42 forms a traverse supporting point of the yarn 20 to be wound in the winding section 8.
- the tension measuring device 43 is arranged between the first guide section 41 and the second guide section 42.
- the tension measuring device 43 is configured as a load cell type sensor.

- the roller driving section 52 rotatably drives the yarn storage roller 51 with a center axis line thereof as a center. Specifically, a belt 70 is wound around an output shaft 52a of the roller driving section 52 and a coupling member 51a fixed to the inner surface of the yarn storage roller 51, and the yarn storage roller 51 can be rotated by rotating the output shaft 52a.

According to such a configuration, the yarn hooking arm 53 can be rotatably driven around the same rotation axis as the yarn storage roller 51.
- the operation of the arm driving section 55 is controlled independently from the roller driving section 52 by the control section 60. Therefore, in the present embodiment, the rotation speeds of the yarn storage roller 51 and the yarn hooking arm 53 can be differed.
- the arm driving section 55 is a servo motor, a stepping motor, or the like.
- Each winding unit 2 includes the control section 60.
- the control section 60 is configured by hardware such as a CPU, a ROM, and a RAM (not illustrated), and software such as the control program stored in the RAM. The hardware and the software cooperatively operate to control each configuration of the winding unit 2.
- the control section 60 includes, as a configuration for controlling the arm driving section 55, a deviation calculating section 61, a PID control value determining section 62, and a limiter 63.
- the deviation calculating section 61 of the control section 60 is input with a tension measurement value measured by the tension measuring device 43. Furthermore, a tension target value derived from the winding conditions such as the type of yarn 20 and the yarn travelling speed is input to the deviation calculating section 61. The deviation calculating section 61 calculates the deviation of the two input values, and outputs the calculated deviation to the PID control value determining section 62.
- the PID control value determining section 62 calculates a control value for controlling the torque of the arm driving section 55 by a known PID control based on a deviation, time integral of the deviation, and time derivative of the deviation.
- the control value may be calculated based only on the deviation, and the control value may be calculated based only on the deviation and the time integral thereof.
- the feedback control other than the PID may be used.
- the PID control value determining section 62 outputs the control value calculated as above to the limiter 63.
- the limiter 63 defines an upper limit of the control value of the arm driving section 55.
- the limiter 63 outputs the relevant threshold to the arm driving section 55 as the control value.
- the limiter 63 outputs the input value as it is.
- the control value calculated as above is input to the arm driving section 55, and the torque of the arm driving section 55 is adjusted based on the control value.
- the control section 60 carries out the feedback control as necessary, so that even if the travelling speed of the yarn is high, the yarn hooking arm 53 can apply a desired tension to the yarn 20.
- the yarn winding device of the present embodiment includes the bobbin supporting section 7, the yarn storage roller 51, the winding section 8, the tension measuring device 43, the yarn hooking arm 53, the arm driving section 55, and the control section 60.
- the bobbin supporting section 7 can supply the yarn 20.
- the yarn storage roller 51 is rotatably driven by the roller driving section 52, so that the yarn 20 is pulled out from the yarn supplying bobbin 21 of the bobbin supporting section 7 and the yarn 20 is stored on the surface.
- the winding section 8 pulls out the yarn 20 stored on the yarn storage roller 51 to form the package 30.

- the arm driving section 55 rotatably drives the yarn hooking arm 53.
- the control section 60 feedback controls the arm driving section 55 based on the measurement result of the tension measuring device 43 to adjust the amount of tension applied by the yarn hooking arm 53.
- the yarn travelling direction of the yarn storage roller 51 in the present invention is a direction in which the yarn wound around the outer circumferential surface of the yarn storage roller 51 advances by being pushed by the newly wound yarn, and is the same direction as the axial direction of the shaft 54a.
- the tension on the downstream of the yarn storage roller 51 is measured, and the arm driving section 55 is controlled based on such a measurement result, the tension of the yarn 20 to be wound into the package 30 becomes the desired tension.
- the quality of the package 30 can be improved while the interruption of the winding of the yarn 20 is prevented.
- a yarn storage device 18a of the first alternative embodiment includes a resistance torque generating section 56.
- the resistance torque generating section 56 is a load such as a torque limiter attached between a shaft 54a and at least an inner surface of the yarn storage roller 51.
- the resistance torque generating section 56 thereby generates a torque against the relative rotation of the yarn storage roller 51 and the yarn hooking arm 53, and integrally rotates.
- the yarn hooking arm 53 can be relatively rotated with respect to the yarn storage roller 51 by driving the arm driving section 55 at greater than or equal to the above torque.
- the operation of the arm driving section 55 is stopped and the yarn storage roller 51 and the yarn hooking arm 53 are integrally rotated by the torque of the resistance torque generating section 56.
- the fluctuation of the tension is large, the fluctuation of the tension can be prevented by driving the arm driving section 55 and relatively rotating the yarn hooking arm 53.

- the transmission mechanism 54 includes a clutch 54b in addition to the shaft 54a.
- the clutch 54b is a constituent element of the transmission mechanism 54.
- the clutch 54b switches the transmission or cutting of the driving force from the arm driving section 55 to the yarn hooking arm 53.
- the yarn storage roller 51 and the yarn hooking arm 53 can be integrally rotated without stopping the drive of the arm driving section 55 as in the first alternative embodiment. Therefore, for example, the yarn hooking arm 53 can be immediately decelerated by rotating the shaft 54a at a rotation speed slightly lower than the yarn storage roller 51 and connecting the clutch 54b when desiring to decelerate the yarn hooking arm 53.
- the transmission mechanism 54 of the yarn storage device 18c of the third alternative embodiment includes a torque limiter 54c in addition to the shaft 54a.
- the torque limiter 54c is attached to connect the shaft 54a divided in half.
- the two shafts 54a integrally rotate when a torque smaller than a predetermined value is applied by the torque limiter 54c, and the two shafts 54a relatively rotate when a torque greater than or equal to the predetermined value is applied.
- roller driving section 52 and the arm driving section 55 have at least one part arranged inside the yarn storage roller 51, but the roller driving section 52 and the arm driving section 55 may be arranged outside the yarn storage roller 51.
- the yarn hooking arm 53 may be arranged outside the yarn storage device 18.
- the tension measuring device 43 may be, for example, a tension sensor using a spring and/or a piezoelectric element, instead of a load cell type.
- control section 60 adjusts the torque of the arm driving section 55 based on the measured tension, but the position (rotation angle) and the speed (rotation speed) may be adjusted instead of the torque.
- the present invention may be applied to other yarn winding devices such as a spinning machine.
- a spinning section adapted to spin the spun yarn from the sliver corresponds to the yarn supplying section.
