FIG. 5 is a schematic view showing in sequence the state in which the wire 3 is wound around the winding drum 2 having the wire guide member 1 mounted thereon. FIG. 5A shows a state in which the wire 3 is wound around the winding drum 2 only once. As shown in FIG. 5A, the first winding is wound from the end of the winding drum 1. Then, as shown in FIG. 5B, the second and third winding wires 3 are sequentially wound. At this time, since the wire guide member 1 is attached to the winding drum 2 in advance, the second wire 3 is inserted into the recess 1b closest to the first wire 3, and the third wire 3 is wound twice. The recess 1 closest to the eye wire 3
inserted in b.

As a result, the wire 3 is wound in sequence.
There will be no more gaps than necessary. In particular, when the winding of the wire 3 is once stopped and the winding of the wire 3 is performed again after the tension of the wire 3 is removed, the gap between the wound wires 3 is likely to widen. By providing the member 1, it is possible to wind the wire 3 wound around each winding around the winding drum 2 in a state where the wire 3 is always kept close to each other.

FIG. 6 shows an example in which the eaves 2b is provided on the flange portion 2a of the winding drum 2 in order to securely fix the wire guide member 1 to the winding drum 2. Thus, by sandwiching the wire guide member 1 between the eaves 2b and the cylindrical surface of the winding drum 2, the wire guide member 1 can be securely fixed.

After the wire 3 of the first layer is wound around the winding drum 2 without any gap, the surface on which the wire 3 of the second layer is wound is 1
By the wire 3 of the layer, it becomes uneven. Therefore, if the wire 3 of the second layer is continuously wound in a state where tension is applied to the wire 3, the wire 3 of the second layer can be wound without a gap. However, if the first layer is discarded and the wire 3 is always wound and the wire 3 is actually wound from the middle of the second layer,
The wire 3 is not tensioned. If you start winding from this state, 2
The wire 3 of the layer is wound around. Embodiment 2
In this case, the wire 3 is prevented from having a gap even in such a case.

FIG. 7A shows a state in which the wire 3 of the first layer has been wound. Since the wire guide member 1 described in the first embodiment is used when winding the wire 3 of the first layer, the wire 3 of the first layer can be wound up without a gap. In this state, the second embodiment is placed on the wire 3 of the first layer.
The wire guide member 4 is mounted. The basic shape of the wire guide member 4 is the same as that of the wire guide member 1.
By further winding the wire 3, the wire 3 of the second layer is sequentially wound on the wire guide member 4. Since the wire guide member 4 is provided with the convex portion 4a and the concave portion 4b, the wire 3 is sequentially accommodated in the concave portion 4b,

In the second embodiment, the wire 3 can be wound up without any gap even when further winding is performed with reference to the state shown in FIG. 7B. Figure 7
When the winding is further performed with reference to the state of (b), the wire 3 is not tensioned until the start of winding, and therefore, if the wire guide member 4 is not provided, a gap is generated in the wire 3 at the start of winding. However, by providing the wire guide member 4, the concave portion 4 closest to the last wound wire 3 even at the start of winding.
The newly wound wire 3 can be accommodated in b. This prevents a gap from being formed in the wire 3 of the second layer, prevents the wire 3 of the third layer from entering the gap of the wire 3 of the second layer, and prevents the wire 3 from being damaged. You can Then, it is possible to design a winch in which winding is started in the middle of the second layer, and it is possible to increase the degree of freedom in the specification of the winch.

If a step or uneven shape is formed at the end of the wire guide member 4, the wire 3 may hit the step or uneven shape and damage the wire 3. However, as shown in FIG. 7, the end 4c has a smooth curved surface. By setting the shape, the wire 3 of the second layer can be wound at a predetermined position without damaging the wire 3.

FIG. 8 shows an example in which a convex portion 4d and a concave portion 4e for engaging with the wire 3 of the first layer are provided on the back surface of the wire guide member 4. Thus, by providing the convex portion 4d and the concave portion 4e on the back surface, the wire guide member 4 can be reliably positioned. Further, by providing the convex portion 4d and the concave portion 4e, the strength of the wire guide member 4 can be increased, and the deformation of the wire guide member 4 due to the tension of the wire 3 can be suppressed.

Moreover, since the wire guide member is separate from the winding cylinder, a normal winding cylinder can be used. Therefore, it is possible to minimize an increase in cost and accurately position the wire.

Further, since the width of the wire guide member is set to a width corresponding to an angle of 20 ° or more about the axis of the winding cylinder,
The wire can be reliably positioned without being restricted by the diameter of the winding drum.

Further, since the length in the longitudinal direction is substantially the same as the distance between the flanges on both sides of the body separate from the winding cylinder, the wire guide member can be reliably fixed by being sandwiched between both flanges. Therefore, it is possible to prevent the wire guide member from coming off the winding drum during winding.
