Therefore, the inner diameter of the winding drum 3 does not have to be long enough to accommodate the mouthpiece at the end of the hose, and can be as short as possible within a range in which the core portion described later can be accommodated. A method for winding the hose will be described later.

<Fire hose winding method>
The winding method using the hose winder according to each embodiment will be described in detail.

≪Winding method with fire hose winder according to Example 1≫
When winding a single hose using the hose winder according to the first embodiment, first lay the hose straight on the ground over the entire length, and then attach a base (either male or female) at one end of the hose. It arrange | positions inside the winding drum 3 through the slit 3a.

  Next, as shown in FIG. 7, if the gripping portion 8 of the operating rod 1 is grasped and the winding drum 3 is rotated on the hose H laid on the ground, the edge of the slit 3a becomes the winding start point. The hose H can be wound up over the entire length easily and appropriately. At this time, since the spacer portion 3B of the winding drum 3 provides a space between the operation rod 1 and the winding portion 3A, the hose does not enter between the operation rod 1 and the winding drum 3. Even if the hose is displaced and wound to the operation rod 1 side, the spacer portion 3B corresponds to this.

  Further, as shown in FIG. 8, when the guide unit 10 is provided in the winder according to the first embodiment, the hose before being wound is temporarily lifted by the first roller unit 12 while the winding drum 3 is wound. Positioning is performed so as to be taken up by the take-up unit 3A, and it is returned to the ground by the second roller unit 13 and waits for being taken up by the take-up unit 3A of the take-up drum 3. Therefore, the hose can be reliably guided to the winding portion 3 </ b> A of the winding drum 3. In addition, since the cap of the hose cannot pass through the guide portion 10, the hose is of course removed from the guide portion 10 when the cap at the other end of the hose (the cap on the winding end point side) reaches the front of the guide portion 10. It is.

≪Method of winding with a fire hose winder according to Example 2≫
When the hose is wound twice using the hose winder according to the second embodiment, first, the middle portion of the hose is folded to form a double end portion, and the double end portion is wound around the core portion. As shown in FIG. 15, the winding core is disposed in the winding drum 3 through the slit 3a.

  Preferably, the double end portion described above is formed so as to be shifted from the center in the length direction of the hose, and the hose is divided into a short winding target portion H1 and a long winding target portion H2. As shown in FIG. 4, the short winding target portion H1 is wound from the lower side of the winding drum 3, and the long winding target portion H2 is wound from the upper side of the winding drum 3, whereby the hose is wound on the winding drum 3. Can be reliably double wound.

  In addition, in the winding tool according to the second embodiment, since the guide portion 20 is provided above the winding drum 3, the winding portion of the winding drum 3 while the long winding target portion H2 is once lifted. It is aligned so as to be wound around 3A, falls to the winding portion 3A side of the winding drum 3 by its own weight, and is wound up.

  In addition, since the long winding target portion H2 passes through the guide portion 20 above the winding drum 3 as described above, the distance between the long winding target portion H2 and the short winding target portion H1 is adjusted. The difference in length can be absorbed, and the take-up drum 3 can be made to reach the bases that are the ends of both portions H1 and H2 almost simultaneously. Therefore, since it is sufficient to arrange the two bases from the beginning and place them on the ground, it is not possible to make the work complicated such as which base is placed far away.

  In the winder according to the second embodiment, the winding drum 3 is configured such that the stepped portion is formed by setting the outer diameter of the spacer portion 3B to be larger than the outer diameter of the winding portion 3A. The hose can be reliably wound up by the winding portion 3A. Also in the winder according to the second embodiment, the role of the spacer portion 3B of the wind drum 3 is the same as that in the first embodiment, and the hose is prevented from entering between the operation rod 1 and the wind drum 3. And even if the hose is shifted and wound to the operation rod 1 side, the shifted hose is received and dealt with.

  In addition, it is also arbitrary to implement the double winding winding method according to the present invention by omitting the guide portion 20 of the winding device according to the second embodiment. In this case, the operator may lift the long winding target portion H2 with one hand and operate the operation rod 1 with the other hand. Further, in the first embodiment, the guide portion 10 shown in FIG. 8 is provided on the front side in the traveling direction of the winding drum 3, and a short winding target portion H 1 is provided to the winding portion 3 A of the winding drum 3 by the guide portion 10.
