The winding tightness is adjusted. For example, when the operating member 61 is strongly pressed down, the winding adjustment pressing plate 6 causes the seedling collector to be wound while being strongly pressed. Therefore, the seedling collector becomes a compact roll shape, and the storage space is saved. On the other hand, when the operating member 61 is pushed down weakly or is not operated at all, the winding adjustment pressing plate 6 causes the seedling collector to be wound while being softly pressed. For this reason, the seedling collector becomes a fluffy roll shape and easily spreads in the sea at the next use. These can be easily adjusted to suit the fisherman's tastes.

Further, in the present embodiment, while the seedling collector is being wound, as shown in FIG. 6D, the vertical roller 4 regulates the positions of both ends of the seedling collector, which is an abbreviation for the winding mandrel 3. Send to the center position. For this reason, the seedling collector is wound up without shaking from side to side, and becomes a beautiful roll. On the other hand, the horizontal roller 5 abuts on the upper and lower surfaces of the seedling collector and is flattened before being sent to the winding mandrel 3. Therefore, the seedling collector is wound without being bulky, and the volume after winding is suppressed.

As shown in FIG. 6E, by the time the winding of the seedling collector is completed, the wound seedling collector strongly presses the main winding rod 31 and the secondary winding rod 32 in the direction of bringing them closer to each other. To do. Further, after the winding is completed, as shown in FIG. 6 (f), when the winding adjustment pressing plate 6 is lifted and the seedling collector is tightly tied with a rope, the main winding rod 31 and the secondary winding rod 32 are obtained. Is further squeezed. However, in the present embodiment, the spacing member 33 suppresses the deformation of the main winding rod 31 and the secondary winding rod 32, and maintains the distance between the two. Therefore, the main winding rod 31 and the secondary winding rod 32 maintain a state of being substantially parallel to each other, so that the seedling collector after winding can be easily pulled out.

After tying the wound seedling collector with a rope, as shown in FIG. 6 (g), when the seedling collector is pulled toward the open end side of the main winding rod 31 and the secondary winding rod 32, seedlings are collected. The vessel slides along the main take-up rod 31 and the follow-up take-up rod 32 and is easily and quickly pulled out. As a result, as shown in FIG. 6H, the seedling collector is fixed in a compact and neatly rolled state, and can be stored.
