Description

  The present invention relates to a thread winder for winding a handicraft thread such as an embroidery thread around a thread spool, and a thread winder set including the thread winder.

  Embroidery threads used in the field of handicrafts are sold, for example, in a so-called “skein” state that is folded back and bundled at a predetermined length. The embroidery thread in the skein state has the disadvantage that the thread is easily broken and entangled during embroidery work. For this reason, a method may be employed in which an embroidery thread is wound around a spool made of a rectangular flat board and the embroidery work is performed using the embroidery thread wound around the spool.

  A spool made of the above-mentioned mount or the like is generally a simple one for winding up the embroidery thread by hand, so that the embroidery thread wound around the spool is likely to be uneven and has a poor appearance. Tend to be. In the field of handicrafts with high hobbies, there are cases in which good looks such as beauty and cuteness are required even with such handicrafts such as spools. However, the above-described spool made of a mount cannot meet such a demand for good appearance.

  The present invention has been conceived under such circumstances, and a thread winder capable of winding a handicraft thread such as an embroidery thread into a bobbin with good appearance and efficiency. It is an issue to provide.

  In order to solve the above problems, the present invention takes the following technical means.

  The yarn winder provided by the first aspect of the present invention is a yarn winder for winding a yarn around a disk-shaped bobbin, which rotates around a frame and a first axis with respect to the frame. A rotating member supported in a possible manner, an operating portion for rotating the rotating member, a threading hole formed in a portion of the rotating member spaced from the first axis by a predetermined distance, and the frame. On the other hand, a rotating shaft supported rotatably around a second axis different from the first axis, and interlocking means for rotating the rotating shaft at a predetermined pitch in conjunction with the rotating operation of the rotating member. A fixing means for fixing the bobbin to the rotary shaft, and when the bobbin is fixed to the rotary shaft, the bobbin is threaded through the rotating member. Inside the rotation trajectory of It is characterized by being configured to rolling intersect the plane containing the orbit.

  According to the bobbin winder having such a configuration, the embroidery thread or the like can be efficiently wound on the bobbin by fixing the disc-shaped bobbin to the rotating shaft and operating the operation unit. Specifically, the thread end of the thread that has passed through the threading hole of the rotating member is hooked on a disk-shaped bobbin having a predetermined shape, and the disk-shaped bobbin is fixed to the rotating shaft, and the operation unit is operated to rotate. Rotate the member. Since the disk-shaped bobbin fixed to the rotating shaft intersects the plane including the rotating track inside the rotating track of the threading hole associated with the rotating operation of the rotating member, the rotating member rotates when the rotating member rotates. The yarn led out from the threading hole to the bobbin side is wound up by a disk-shaped bobbin. At this time, the yarn continues to be supplied to the bobbin side through the threading hole. Further, since the rotating shaft rotates at a predetermined pitch in conjunction with the rotating operation of the rotating member, the portions of the bobbin wound with the yarn are sequentially shifted at a constant pitch. As the disk-shaped bobbin, for example, one having a plurality of concave portions formed in a gear shape at a constant pitch on the outer peripheral edge can be suitably used. If a bobbin having a gear-shaped concave portion is used, the portion around which the yarn is wound moves regularly. Accordingly, the appearance of the yarn wound around the bobbin has a good appearance.

Accordingly, the rotating body is rotated by a predetermined amount, and the rotation shaft is rotated at the predetermined pitch by the engagement between the gear formed on the rotating body and the gear formed on the rotating shaft. ing.

  According to such a configuration, the rotational force applied to the rotating member by rotating the operation unit is accurately transmitted to the rotating shaft by the gear mechanism interposed in the rotating member or the rotating shaft. Therefore, the configuration employing such a gear mechanism is suitable for appropriately rotating the rotating shaft at a predetermined pitch.

  In a preferred embodiment of the present invention, the rotation of the rotating shaft is allowed only when the rotating shaft is rotated by the interlocking means, and the rotation of the rotating shaft is restricted except when the rotating shaft is rotated. A lock mechanism capable of

  In a preferred embodiment of the present invention, the lock mechanism includes a locking member that engages with a gear of the rotation shaft to restrict rotation of the rotation shaft, and a guide portion formed on the rotation member. Accordingly, the engagement state between the gear of the rotation shaft and the locking member is released only when the rotation shaft is rotated, and the engagement state is maintained except when the rotation shaft is rotated. Has been.

  According to such a configuration, it is possible to appropriately prevent a problem such that the rotating shaft rotates inappropriately except during a predetermined rotation.

  In a preferred embodiment of the present invention, the fixing means attaches the bobbin to the tip of the rotating shaft so as not to be relatively rotatable, and the pinning member sandwiches the bobbin between the rotating shaft and the thickness of the bobbin. It is configured to restrict movement in the direction.

  According to such a structure, the fixed state with respect to the rotating shaft of a bobbin can be maintained appropriately.

  In a preferred embodiment of the present invention, the first axis and the second axis are perpendicular to each other.

  According to a second aspect of the present invention, there is provided a yarn winder set comprising the yarn winder described in the first aspect of the present invention described above and a disk-shaped thread winder attached to the yarn winder. .

When the step portion 24 is fitted to the support portions 112 and 122 of the frame 1, the rotating member 2 is supported so as to be rotatable around a predetermined axis C <b> 1 with respect to the frame 1. Further, a threading hole 25 is formed in the rotary member 2 on the inner surface of the cylindrical portion 21 so as to extend from the vicinity of the outer periphery of the lid portion 22 substantially in parallel with the axis C1. In the present embodiment, as shown in FIG. 3, the threading holes 25 are provided at two locations facing each other across the axis C1. The operation portion 23 is formed so as to extend from the cylindrical portion 21 or the lid portion 22 of the rotating member 2 so as to extend outward in the radial direction of the cylindrical portion 21. A grip portion that extends substantially parallel to the axis C <b> 1 is formed at the tip of the operation portion 23, so that the user can easily rotate the rotating member 2 by grasping it with the hand. Further, threading holes 26 and 27 are provided at appropriate positions of the operation unit 23.

  The rotating shaft 3 includes a shaft portion 31 that has a tubular shape as a whole, and a gear 32 (having 16 teeth) formed on the outer surface of the lower end portion of the shaft portion 31. The rotary shaft 3 is mounted such that the lower end portion of the shaft portion 31 is fitted on the shaft portion 113 of the lower frame 11 and the center portion of the shaft portion 31 is fitted on the tube portion 123 of the upper frame 12. Has been. Thereby, the rotating shaft 3 is supported so as to be rotatable around a predetermined axis C <b> 2 with respect to the frame 1. A step portion 33 is formed on the outer surface of the rotating shaft 3. The stepped portion 33 abuts on the flange portion 124 formed to protrude from the inner surface of the base portion of the cylindrical portion 123 of the upper frame 12, so that the rotation shaft 3 is prevented from moving in the direction along the axis C <b> 2. In the yarn winder A of the present embodiment, the axis C1 that is the rotation center of the rotating member 2 and the axis C2 that is the rotation center of the rotating shaft 3 are configured to be orthogonal to each other.

  The interlocking mechanism 4 is for rotating the rotating shaft 3 at a predetermined pitch in conjunction with the rotating operation of the rotating member 2, and as shown in FIG. 2 or FIG. 4, the step portion 24 of the rotating member 2. A protrusion 241 formed on the outer peripheral surface of the rotating member 2, a rotating body 41 provided on the side of the rotating path of the rotating member 2, and a gear 32 of the rotating shaft 3. The protrusion 241 is provided at a position (one place) corresponding to the operation unit 23 of the rotating member 2. The rotating body 41 is pivotally supported by a pin 114 erected from the base portion 111 of the lower frame 11, and is rotatable about an axis parallel to the axis C2. The rotating body 41 is configured such that two small gears 411 and 412 arranged vertically are rotated together. The small gear 411 is a portion that engages with the protrusion 241 provided on the rotating member 2 by the rotating operation of the rotating member 2, and the small gear 412 is a portion that engages with the gear 32 of the rotating shaft 3. As can be understood from such a configuration, when the rotating member 2 rotates once, the rotating body 41 rotates by one pitch of the small gear 411 due to the engagement between the protrusion 241 and the small gear 411, and the rotating shaft 3 The gear 32 rotates by one pitch by the engagement between the small gear 412 and the gear 32.

  The lock mechanism 5 allows the rotation of the rotary shaft 3 only when the rotary shaft 3 is rotated by the interlock mechanism 4 and restricts the rotation of the rotary shaft 3 except when the rotary shaft 3 is rotated by the interlock mechanism 4. Yes, as shown in FIG. 4 or FIG. 5, the guide member 242 provided on the rotating member 2 and the locking lever 51 are provided. The locking lever 51 has a substantially U-shape as a whole, and an engaging recess 511 for engaging with a part of teeth of the gear 32 of the rotating shaft 3 is formed at one end thereof, and the other end. A protrusion 512 extending upward is formed on the part. The locking lever 51 is disengaged from the gear 32 when the engaging recess 511 is close to the gear 32 of the rotating shaft 3 and engaged with the gear 32, and the engaging recess 511 is separated from the gear 32. In a predetermined storage portion of the lower frame 11, it is slidably mounted (slids in the left-right direction in FIG. 4).

  As shown in FIG. 5, the guide portion 242 includes a first guide portion 243 that protrudes in a hook shape along the rotation direction of the rotating member 2 on the outer periphery of the step portion 24 of the rotating member 2, and a protrusion. And a second guide portion 244 having a shape. The first guide portion 243 has a notch 245 at a position corresponding to the protrusion 241, and inclined surfaces 243 a toward the protrusion 241 are provided at both ends sandwiching the notch 245. The second guide portion 244 is formed at a position facing the protrusion 241 with the notch 245 interposed therebetween, and inclined surfaces facing the inclined surface 243a of the first guide portion 243 at both ends in the rotation direction of the rotating member 2. 244a is provided.

  The protrusion 512 of the locking lever 51 is located on the right side of the first guide portion 243 as shown in FIGS. 2 and 4 except when the rotary shaft 3 is rotated. Thereby, the engagement recessed part 511 of the latch lever 51 and the gearwheel 32 of the rotating shaft 3 engage. When the rotating member 2 is rotated, the protrusion 512 of the locking lever 51 is guided by the inclined surfaces 243a and 244a and passes through the notch 245 when the rotating shaft 3 on which the interlock mechanism 4 acts is rotated toward the protrusion 241 side. Displace. At this time, the engagement state between the engagement recess 511 of the locking lever 51 and the gear 32 of the rotating shaft 3 is released. In FIG. 5, a state in which the protrusion 512 is displaced relative to the rotating member 2 as the rotating member 2 rotates is indicated by a virtual line. As can be understood from this, the engagement state between the gear 32 of the rotating shaft 3 and the engaging recess 511 of the locking lever 51 is released only when the rotating shaft 3 is rotated by the interlocking mechanism 4. The engagement state is maintained when the rotation shaft 3 is not rotating.

  A stopper member 7 is mounted at an appropriate position on the lower frame 11. The stopper member 7 presses the small gear 411 of the rotating body 41 and the gear 32 of the rotating shaft 3 toward each inward in the radial direction with an appropriate elastic force. Thereby, in the rotation operation of the rotating member 2, rattling due to play of the interlocking mechanism 4 can be prevented, and an appropriate moderation feeling can be given when the rotating shaft 3 rotates by one pitch.

  The fixing unit 6 is for fixing the disc-shaped bobbin S to the rotating shaft 3 in a predetermined posture. The bobbin winding unit 34 formed on the outer surface of the upper end of the shaft 31 of the rotating shaft 3 and the bobbin S And a cylindrical locking pin mounting portion 35 formed on the inner side of the upper end portion of the shaft portion 31. The bobbin mount 34 has a polygonal outer peripheral surface, and when the bobbin thread S is fitted into a polygonal hole (not shown) formed at the center of the bobbin S, the bobbin S cannot be rotated in a horizontal position. It is a part to be attached to. The locking pin 61 has a gripping portion 611, a locking portion 612 that comes into contact with the bobbin winding S, and a shaft portion 613 that is inserted into the locking pin mounting portion 35. A stopper portion is provided at the tip of the shaft portion 613. The step portion 614 is formed to protrude. The locking pin attachment portion 35 has a hole 351 into which the shaft portion 613 of the locking pin 61 is inserted, and a groove portion 352 through which the step portion 614 is passed. When the locking pin 61 is mounted, if the positions of the step 614 of the locking pin 61 and the groove 352 of the locking pin mounting portion 35 are shifted, the step is not affected even if a pulling force acts on the locking pin 61. The portion 614 contacts the lower end of the locking pin mounting portion 35 so that the locking pin 61 does not come out carelessly, and the fixed state in which the pincushion S is sandwiched between the rotary shaft 3 and the locking pin 61 is appropriately maintained. Is done.

  As the bobbin S attached to the bobbin winder A, a gear-like member having a plurality of concave portions formed at equal intervals on the outer peripheral edge is suitably used. The number of recesses formed in the spool S is 16 which is the same as the number of teeth of the gear 32 of the rotary shaft 3.

  Next, usage examples and operations of the yarn winder A configured as described above will be described with reference to the drawings.

  First, a yarn Y to be wound around the spool S is prepared, and the yarn ends are passed through the threading holes 27, 26, 25 of the rotating member 2 in this order as shown in FIG. Then, the thread end led out from the end portion 25 a of the threading hole 25 on the rotating shaft 3 side is hooked on a hook (not shown) provided on the thread winding S, and the thread winding S is fixed to the rotating shaft 3. Here, the spool S fixed to the rotating shaft 3 is in a posture in which a part thereof enters the inner space of the cylindrical portion 21 of the rotating member 2.

  The operation of winding the yarn Y around the spool S is performed by rotating the rotating member 2 around the axis C1. The rotation operation of the rotating member 2 is performed by holding the frame 1 with one hand and holding the operation portion 23 of the rotating member 2 with the finger of the other hand in one direction (for example, clockwise in the right side view of FIG. 6: FIG. This can be done easily by turning in the direction of arrow N1. When the rotating member 2 rotates, the trajectory through which the end portion 25a of the threading hole 25 passes becomes a rotating trajectory that follows a constant circle centered on the axis C1. Here, as can be understood from FIG. 2 and FIG. 6, the bobbin winding S has a posture that intersects the plane including the rotation track perpendicularly inside the rotation track of the end 25 a of the threading hole 25. For this reason, when the rotating member 2 is rotated, the yarn Y led out from the end portion 25a of the threading hole 25 to the spool S side is wound around a portion of the spool S that intersects the plane including the rotation trajectory. The At this time, the yarn Y continues to be supplied to the spool S side through the threading hole 25. In this embodiment, if it is assumed that the spool S does not move at all, the yarn Y is wound up at two recessed portions separated by six. Here, the tension of the yarn when the yarn Y is wound around the spool S can be appropriately adjusted by lightly picking a portion extending from the threading hole 27 of the operation portion 23 with a finger.

  When the rotating member 2 is rotated, the rotating shaft 3 rotates by a predetermined pitch by the action of the interlocking mechanism 4 every time the rotating member 2 rotates once. Specifically, when the operation unit 23 passes through the vertically downward position, the rotation shaft 3 rotates by one pitch counterclockwise in plan view by the gear mechanism interposed in the rotation member 2 or the rotation shaft 3 ( (See FIG. 7). If it does so, the site | part where the thread | yarn Y in the bobbin winding S will move regularly 1 pitch at a time sequentially, and the thread | yarn Y will be wound up in the recessed part which separated 5 on the upper surface of the bobbin winding S (refer FIG. 7). ), The lower surface of the bobbin S is wound up in six recesses. Accordingly, the yarn Y wound around the spool S in this way has a regular appearance, and the appearance is good. Further, if the yarn winder A is used, the yarn Y is automatically wound around the spool S simply by rotating the rotating member 2, so that the yarn winding operation can be performed easily and efficiently. . Since the rotating member 2 can be rotated not only in the direction of the arrow N1 in FIG. 6 but also in the opposite direction, the rotating direction of the rotating member 2 is a direction that is easy for the user to operate. What is necessary is just to be convenient regardless of whether the user is right-handed or left-handed.

  In the yarn winder A, since the lock mechanism 5 is provided, the rotation of the rotation shaft 3 is allowed only when the rotation shaft 3 is rotated by the interlock mechanism 4, and the rotation of the rotation shaft 3 is restricted at other times. . For this reason, it is prevented that the rotating shaft 3 rotates unfairly except at the time of predetermined rotation.

  Further, in the yarn winder A, the stopper member 7 is provided, so that a malfunction such as a rotation of two pitches or more when the rotating shaft 3 rotates is prevented, and the rotating member 2 rotates each time it rotates. It is guaranteed that the shaft 3 rotates by one pitch. Therefore, the stopper member 7 plays a role of causing the interlocking mechanism 4 to function properly in addition to the advantages of preventing the interlocking mechanism 4 from rattling and feeling moderation during operation.

  While specific embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.
