Patent No. 3641198

  According to the technique of Patent Document 1, the fishing line can be wound around the spool in a tension-free state. However, depending on the type of yarn, there are some which are better wound on the spool in a tensioned state, and it is desirable that the tension be different depending on the type of yarn.

  An object of this invention is to provide the yarn winding apparatus which can wind up a thread | yarn in the state which applied desired tension among various tension | tensile_strength.

  The yarn winding device according to one aspect of the present invention includes a yarn supply unit. In the thread supply means, a long thread, for example, a fishing line is accommodated around the axis of the thread accommodating part, the axis of the thread accommodating part is rotated by the thread accommodating part drive means, and the thread is removed from the thread accommodating part. It is paid out. The spool driving means rotates the spool at a predetermined spool rotation speed around the spool axis so that the thread fed from the thread supply means is wound substantially perpendicularly to the spool, that is, the spool axis. A yarn moving means is provided between the yarn supplying means and the spool driving means. The yarn moving means moves the yarn fed from the yarn supplying means at a constant speed along the axial direction of the spool. A tension detecting means is provided between the yarn supplying means and the yarn moving means, and detects the tension of the yarn. The control means controls the speed of the thread accommodating portion driving means to be slower than the speed of the spool driving means so that the tension detected by the tension detecting means becomes a tension selected from a plurality of predetermined tensions. To do.

  In the yarn winding device configured as described above, the tension detecting means detects the tension, and the yarn accommodating unit driving means is set so that the detected value becomes a tension selected from a plurality of predetermined tensions. Since the control means controls, the yarn can be wound with a desired tension. In addition, since the yarn supply means is configured so that the yarn accommodation section driving means rotates the shaft of the yarn accommodation section to feed out the yarn, the speed of the yarn accommodation section can be easily controlled to a desired value. it can. For example, if the feeding unit configured separately from the yarn storage unit forcibly feeds the yarn, the feeding unit may slip the yarn, and the yarn is fed at a desired speed. In order to feed out, it is necessary to frequently control the feeding speed in the feeding unit, and it is difficult to perform stable control. However, as in the present invention, when the yarn accommodating portion driving means directly rotates the yarn accommodating portion, slip or the like hardly occurs and the yarn accommodating portion can be easily fed out at a desired speed.

  As the tension detection means, for example, a roller that contacts the yarn is provided, and a rotation detection means is provided on a bar to which the roller is coupled, and the bar rotates from a reference position in accordance with the tension of the yarn. . If comprised in this way, the rotation angle of a bar will change according to the tension | tensile_strength of a thread | yarn, and tension | tensile_strength will be converted into a rotation angle and it will be output.

  The yarn supply means may be a skein wound around the yarn holding part. When skein is used, the thread held by the thread supply means is not twisted.

  As described above, according to the present invention, the yarn can be wound on the spool in a state where a desired tension is applied among various tensions, and the yarn supply unit used at that time is used for tension control. Since the rotational speed of the driving means of the yarn accommodating portion is adjusted, the yarn does not slip easily and the tension can be accurately controlled.

It is a top view of the yarn winding device of one embodiment of the present invention. It is a front view of the yarn winding device of FIG. FIG. 2 is a perspective view of a tension detector used in the yarn winding device of FIG. 1. It is a block diagram of the yarn winding device of FIG.

  A yarn winding device according to an embodiment of the present invention uses, for example, a fishing line as a yarn to be wound. As shown in FIG. 1, a yarn supplying unit disposed on a base 2, for example, a raw yarn supplying unit 4 is used. have. The raw yarn supply unit 4 has a rotating shaft 6. A bearing 8 is attached to one end of the rotating shaft 6, and a driving means for yarn supplying means, for example, a motor 10 is attached to the other end. As the motor 10, it is desirable to use a step motor. Accordingly, when the motor 10 is rotated, the rotating shaft 6 is also rotated. One end of a pair of cross arms 12, 12 linked in an X shape is linked to the rotary shaft 6, and the outer end, which is the other end of the cross arms 12, 12, is connected to the rotary shaft 6. A horizontal arm 14 is attached in parallel. As shown in FIG. 2, a plurality of these are attached around the rotating shaft 6 at predetermined angles. A thread, for example a skein fishing line 16, is hung around each horizontal arm 14. These arms 12, 12, and 14 form a yarn accommodating portion. By rotating the motor 10, the fishing line 16 can be fed out from the raw yarn supply unit 4.

  As shown in FIG. 2, the fishing line 16 of the raw yarn supply unit 4 is drawn out from a window 18 formed in the base 2 to the lower side of the base 2 and is provided on a side of the window 18, for example, tension detection means. It comes into contact with the roller 22 of the container 20 and is led out from the window 18 above the base 2 again. Details of the tension detector 20 will be described later.

  The fishing line 16 that has passed through the tension detector 20 is supplied to a line moving means, for example, a slide mechanism 26 via a roller 24. The slide mechanism 26 has a shaft, for example, a screw rod 28, which is arranged in parallel with the rotation shaft 6 of the raw yarn supply unit 4, one end of which is rotatable to the bearing 30 and is prevented from moving in the length direction. At the other end, a driving means for moving means, for example, a motor 32 is attached. A screwing member 32 is screwed onto the screw rod 28, and a support base 34 is attached on the horizontal upper surface thereof. Accordingly, when the motor 32 is rotated forward and backward, the support base 34 reciprocates along the screw rod 28. The support base 34 is a rectangular plate having a length direction arranged at right angles to the screw rod 28 and the rotary shaft 6, and a roller 36 is rotatably attached to an end of the raw yarn supply unit 4. A roller 38 is also attached to the opposite end. The roller 38 has a diameter larger than that of the roller 36, and these rotation shafts are arranged in parallel to the length direction of the screw rod 28. The fishing line 12 that has passed through the roller 24 is looped over the roller 38 and folded back, is looped back over the roller 36, and is led out to the side opposite to the raw thread supply unit 4.

  Spool driving means, for example, a yarn winding unit 40 is provided on the opposite side of the raw yarn supply unit 4 with the slide mechanism 26 interposed therebetween. The yarn winding unit 40 has a shaft 42 arranged in parallel with the screw rod 28, one end of the shaft 40 is rotatably supported by a bearing 42, and the other end of the yarn winding unit driving means, for example, a motor 44. Is attached. A plurality of spools 48 are attached to the shaft 42. The spool 48 is provided with a flange 48b having a diameter larger than the diameter of the body 48a at both ends of the cylindrical body 48a. The center of the body 48a is inserted into the shaft 42, and the spools 48 are separated from each other. It is attached to the shaft 42 as possible. Of these spools 48, the tip of the fishing line 16 is fixed to the spool 48 closest to the motor 44. By rotating the motor 44, the fishing line 16 is wound around one spool 48, and when a predetermined amount is wound, the adjacent spools are wound. A fishing line is wound around each spool 48 in the same manner.

  When the motor 44 rotates each spool 48 at a constant speed set based on the diameter and length of the body 48a of the spool 48, the diameter of the fishing line 16, and the length of the fishing line 16 wound around the spool 48. The fishing line 16 is wound on the spool 48. During this winding, every time the fishing line 16 is wound around the spool 48, the slide mechanism 26 moves in the length direction of the screw rod 28 by the diameter of the fishing line 16. By repeating this, the fishing line 16 is wound around the spool 48 in parallel. When the fishing line 16 is wound from one end of the spool 48 to the other end, the slide mechanism 26 starts moving in the opposite direction, and the fishing line 16 is wound in multiple layers. When the fishing line of a predetermined length is wound in this way, the fishing line 16 is wound on the adjacent spool 48 in the same manner.

  As shown in FIG. 3, the tension detector 20 has a rotation detector, for example, a rotary encoder 50 on the lower surface of the side of the window 18 of the base 2, and an L-shaped rotation shaft of the rotary encoder 50. The tip of the vertical portion of the lever 52 is attached, the horizontal portion of the lever 52 advances below the window 18, and the roller 22 described above is rotatably attached to the tip of the horizontal portion. When the fishing line fed from the raw yarn supply unit 4 is applied to the roller 22 and the tension of the fishing line is zero, the vertical portion of the lever 52 is vertical, and when the fishing line 12 is tensioned, the lever 52 Rotates, and the rotary encoder 50 also rotates. This rotation is rotated to an angle at which one end of the lever 52 is coupled to the joint with the rotary encoder 52 and the other end is attached to the base 2 so that the extension of the spring 54 balances with the tension of the fishing line 16. Thereby, the tension of the fishing line 16 is converted into a rotation angle and detected.

  The tension applied to the fishing line 16 is adjusted by making the speed of the motor 10 slower than the rotational speed of the motor 46. Therefore, as shown in FIG. 4, the detection signal of the tension detector 20 is supplied to the control unit 56. The control unit 56 is supplied with a setting signal indicating a tension selected from a plurality of predetermined tensions from the tension setting unit 58. In response to the setting signal, a reference signal corresponding to the selected tension is generated by the reference signal source 60 and supplied to the control unit 56. The control unit 56 controls the speed of the motor 10 so that the detection signal of the tension detector 20 matches the reference signal from the reference signal source 60.

  When a small tension is applied, the speed of the motor 10 is slightly lower than the speed of the motor 46. In this case, the lever 52 is slightly inclined. When a large tension is applied, the speed of the motor 10 is made slower than the speed of the motor 46. In this case, the lever 52 of the tension detector 20 is greatly inclined. When an intermediate tension is applied, the speed of the motor 10 is set to an intermediate speed between the two speeds. In this case, the inclination of the lever 52 is also an intermediate inclination between the two cases.

  In the fishing line winding device configured as described above, the fishing line 16 wound on the spool 48 by the line winding unit 40 is set by making the rotational speed of the motor 10 of the raw line supply unit 4 slower than the rotational speed of the line winding unit 40. The tension is being applied. Moreover, the rotational speed of the raw yarn supply unit 4 can be arbitrarily selected from a plurality of speeds so that a desired tension is applied among a plurality of different tensions set in advance. Further, the tension detector 20 detects the tension of the fishing line 16 and controls the rotational speed of the motor 10 of the raw thread supply unit 4 so that the detected tension matches the desired tension. The tension of the fishing line 16 wound around can always be maintained at a desired tension. Furthermore, since the raw yarn supply unit 4 directly drives the yarn storage unit by the motor 10, the fishing line 16 can be fed out without slipping from the yarn storage unit.

  In the above embodiment, the raw yarn supply unit 4 wound with skein of fishing line is used as the yarn supply means, but instead of this, the raw yarn is supplied by winding the fishing line around a spool larger than the spool 48. It can also be used as a part. In the above embodiment, a fishing line is used as the thread. However, the present invention is not limited to this, and for example, a surgical thread can be wound.
