More specifically, the thread delivery frame 214 reciprocates the guide plate 2113 once along the guide groove 2113a, so that the thread delivery element A reciprocates the case 400 in the left-right direction. Guide the reciprocating motion of Here, the guide groove 2113a has a shape in which the central portion in the longitudinal direction is gently inclined upward as described above. Therefore, as shown in FIG. 3, the yarn delivery frame 214 is lifted in a direction perpendicular to the direction in which the yarn delivery frame 214 reciprocates at the center in the longitudinal direction of the guide plate 2113, so that the rotatable movable connecting rod 2141 a By providing the fixed connecting rod 2141b having the guide portion 2150, the yarn feeding frame 214 can be smoothly lifted in the vertical direction.

The case holding part 220 is for holding the case 400 in order to wind the yarn 10 fed out by the yarn feeding part 210 around the case 400.
As shown in FIGS. 2 and 4, the case holding unit 220 includes a base 221, a power shaft 222, and a slide base 223.

  The base 221 is a base of the case holding part 220, and is made of a substantially U-shaped plate-like member in plan view, as shown in FIGS. 2211. The slide rail 2211 is a rail that guides the reciprocating motion of the slide base 223 in the front-rear direction, and is arranged in a direction orthogonal to the slide rail 2112 and is opposed to the pair of slide rails 2211 as shown in FIG. It is attached to the base 221 so as to.

The power shaft 222 is a power shaft that makes a rotational motion, and is disposed at the approximate center of the case holding portion 220 as shown in FIG.
As shown in FIGS. 1, 2, and 6, the power shaft 222 is connected to the power shaft 212 via a belt 2121 a serving as power transmission means, and is driven by the power of the power shaft 212 of the yarn feeding unit 210. Is done.
With such a configuration, the yarn feeding device 210 and the case holding unit 220 can be driven in an easily interlocked manner, and the energy-saving thread winding device 1 can be obtained.

  The slide table 223 is a table that holds the case 400 and reciprocates on the base 221 in the front-rear direction. As shown in FIGS. 2 and 4, the slide base 223 is made of a plate-like member having a substantially rectangular shape in plan view, and has a case holding base 2231 that holds the case 400 on the upper surface and a slide rail 2211 that is connected to the lower surface. A pair of connecting portions 2232 are provided.

  The case holding base 2231 is a base for holding the case 400, and has a convex portion 2231a as shown in FIG. Here, as shown in FIG. 5, the case 400 includes a main body portion 410 formed of a pair of winding cores and a flange portion 420 formed of flanges 421 and 422 provided in parallel to both ends of the main body portion 410. The case 400 is held on the case holding base 2231 by fitting a concave portion (not shown) provided in the case 400 with the convex portion 2231a.

  The connecting portion 2232 is used to connect the slide base 223 to the slide rail 2211. As shown in FIGS. 2 and 4, the connecting portion 2232 is formed of a substantially U-shaped member in a side view, and the connecting portion 2232 is connected to the slide rail 2211. The slide base 223 is coupled to the slide rail 2211 by being fitted to each other.

Although not shown in detail, the power shaft 222, the slide rail 2211, and the slide base 223 constitute a crank mechanism of the case holding portion 220. As described above, the power shaft 222 is connected to the power shaft 212 via the belt 2121a. With such a configuration, the crank mechanism in the case holding unit 220 can be driven through the power transmission means that follows the power of the crank mechanism in the yarn feeding unit 210.
That is, the rotational motion of the power shaft 222 driven by the power shaft 212 can be converted into the reciprocating linear motion of the slide base 223 in the front-rear direction, and the case 400 can be reciprocated linearly in the front-rear direction. Further, since the slide rail 2211 is disposed in a direction orthogonal to the slide rail 2112, the yarn feeding portion 210 and the case holding portion 220 can reciprocate in a direction orthogonal to each other by a crank mechanism provided therein. .

  In the present embodiment, the configuration is such that the crank mechanism in the case holding portion 220 is driven via the power transmission means that follows the power of the crank mechanism in the yarn unwinding portion 210, but the present invention is not necessarily limited to such a configuration. The crank mechanism in the yarn take-out part 210 may be driven via power transmission means that follows the power of the crank mechanism in the case holding part 220.

In particular, in the present invention, a ratio of one reciprocation time in which the yarn delivery frame 214 in the yarn delivery unit 210 makes one reciprocation in the left-right direction and one reciprocation time in which the case 400 held by the case holding unit 220 makes one reciprocation in the front-rear direction is set. 2 to 1 is set. By adopting such a configuration, the case 400 held by the case holding unit 220 can be reciprocated twice in the front-rear direction while the yarn unwinding frame 214 in the yarn unwinding unit 210 reciprocates once in the left-right direction. Therefore, the thread 10 can be wound around the case 400 in an 8-shape.
The shape of the figure 8 is adjusted by adjusting the stroke length in the left-right direction of the yarn delivery frame 214 of the yarn delivery unit 210 and the stroke length in the front-rear direction of the slide base 223 (case 400) of the case holding unit 220. The shape of figure 8 can be elongated, shortened, or adjusted.

The yarn delivery frame 214 is guided by the guide mechanism so that the yarn delivery element A reciprocates once in the left-right direction by reciprocating once along the guide groove 2113a.
The guide groove 2113a has a shape in which the central portion in the longitudinal direction is gently inclined upward.
Further, the slide base 213 (yarn take-out frame 214, thread take-up element A) of the yarn take-out part 210 and the slide base 223 (case 400) of the case holding part 220 are reciprocated in directions orthogonal to each other by a crank mechanism provided therein. Do.
The ratio of the left and right reciprocation time on the yarn unwinding portion 210 side and the front and rear reciprocation time on the case holding portion 220 side is set to 2: 1.
By configuring the mechanism as described above, it is possible to wind the yarn 10 around the case 400 in an 8-shape, and at the position where the yarn 10 wound around the case 400 intersects, the yarn feeding frame 214 is reciprocated. Can be lifted perpendicular to the direction. For this reason, the thread | yarn 10 wound around the position where the thread | yarn 10 cross | intersects can be made into a position higher in the perpendicular direction than the thread | yarn 10 wound around other positions.
More specifically, as shown in FIG. 5B, the yarn 10 can be wound around the upper surface of the upper flange 421 at the center of the case 400 where the yarn 10 intersects. Therefore, it is possible to easily maintain the tension of the yarn 10 when the yarn 10 is wound around the case 400, and the yarn 10 can be wound around the case 400 more reliably and easily. Therefore, the bobbin winding device 1 with high manufacturing efficiency can be obtained.

  The thickness adjusting means 300 is a means for adjusting the thickness of the yarn 10 wound around the case 400. As shown in FIGS. 1 and 8, the thickness adjusting unit 300 includes a base 310, an extendable arm 320, and a pressing piece 330.

The base 310 forms the foundation of the thickness adjusting means 300.
The telescopic arm 320 is an arm having a pressing piece 330 at the tip and extending and contracting in the vertical direction by a power source such as hydraulic pressure.
The pressing piece 330 is a pressing piece that presses the yarn 10 wound around the case 400 from above. More specifically, the position where the yarn 10 wound around the case 400 intersects is pressed from above.
As shown in FIGS. 1 and 8, the pressing piece 330 has a substantially dice shape, and the position where the yarn 10 wound around the case 400 that reciprocates linearly in the front-rear direction via the power shaft 222 intersects the pressing piece. A sensor (not shown) senses the timing immediately below 330 at a predetermined interval, the extendable arm 320 is extended, and the pressing piece 330 presses the position where the yarn 10 intersects. By adopting such a configuration, an increase in thickness due to the overlap of the yarns 10 at the intersecting position is prevented, thereby preventing the yarn payout A from being caught at the intersecting position of the yarn 10 and smoothing of the yarn payout A. Reciprocal movement can be ensured. Therefore, smooth 8-shaped winding around the case 400 can also be achieved.

  The case 400 is for winding the yarn 10 and is provided in a pair in this embodiment. As shown in FIG. 5, the case 400 includes a main body portion 410 composed of a pair of cores, and a flange portion 420 composed of an upper flange 421 and a lower flange 422 provided in parallel to both ends of the main body portion. Is done. By adopting such a configuration, it is possible to reliably prevent the wound yarn 10 from coming off, and the thread winding device 1 with high work efficiency can be obtained.

Next, the operation of the thread winding device 1 according to the present invention will be described.
First, the case 400 is set in the case holding part 220. In this state, the starting yarn 10 is supplied from the yarn supplying means 100. The yarn 10 supplied from the yarn supply / supply unit 100 is passed through the through hole of the yarn payout A via the guide roller B and set at the winding start position of the case 400. The standby of the thread winding device 1 is completed through the above steps.
After the standby is completed, the bobbin winding device 1 is driven to manufacture the bobbin in which the yarn 10 is wound around the case 400 in an 8-shape.

  The shape, size, number, arrangement position, etc. of the yarn supplying means 100, the yarn winding means 200, the thickness adjusting means 300, and the case 400 constituting the yarn winding device in the present invention are not limited to those of the present embodiment, and are appropriately determined.
