  Next, mainly with reference to FIG. 1 and FIGS. 3 to 7, a hose winding operation by the above-described hose winding device will be described. When winding up the fire hose 64, the hose 64 is folded in two near the longitudinal center and stacked vertically. At this time, the female fitting 95 and the male fitting 97 of the fire hose 64 folded in half are in a somewhat shifted state. In the case where a metal fitting is provided at both ends, such as the fire hose 64, it is folded in half at a substantially central portion in the longitudinal direction, but in the case where there is no such metal fitting, the winding start portion is folded in two. .

Subsequently, the center part of the fire hose 64 folded in half passes between the pair of second guide rollers 36 and 38, passes over the pair of first guide rollers 26 and 28, and further pairs of fourth guide rollers 54, 56, passes through the third guide roller 44 and is guided to the hose take-up portion 66, and the half-folded central portion is inserted into the auxiliary take-up shaft 86 from above the hose take-up portion 66. When this is inserted, the state shown in FIG. 4 is obtained, and the hose 64 to be wound is wound around the main winding shaft 76 and the sub winding shaft 86 in a folded state.

In this state, the fire control hose 64 is folded in half as shown in FIG. 5 by rotating the rotary operation handle 90 in a predetermined direction while lightly pressing the pressing portion 98 of the pressing arm 96 . wound to the Installing section 66. In early this winding, the load applied hose 64 to the sub-winding shaft 86 is acting, the main winding shaft 78 to the sub-winding shaft 86 (second rotational axis 74) (first The rotation shaft 72 ) is relatively rotated, and the first contact portion 80 of the contact member 76 that rotates integrally with the main winding shaft 78 is brought into a first state in which it contacts the sub winding shaft 86 ( After that, the main take-up shaft 78 and the sub take-up shaft 86 rotate integrally to wind up the hose 64. At the time of winding, both sides of the fire hose 64 are guided by the pair of second guide rollers 36 and 38 and the pair of fourth guide rollers 54 and 56, so that the fire hose 64 can be wound up neatly. it can. Further, since the pressing arm 96 is lightly pressed downward, the hose 64 wound around the hose winding portion 66 contacts or presses a predetermined portion of the hose 64 moving on the third guide roller 44, thereby The hose 64 to be wound can be wound while being pulled, and thus the folded hose 64 can be tightly wound. The winding strength of the hose can be adjusted by the pressing force of the pressing arm 96. In the case of winding tightly, the pressing force of the pressing arm 96 is increased to increase the tensile force applied to the hose 64. Good. Thus, the fire hose 64 folded in half can be wound around the hose winding portion 66 as required. When the winding is completed, for example, the state shown in FIG. 6 is obtained.

  In order to remove the fire hose 64 wound up in this way from the hose winder 66, the rotary operation handle 90 is rotated halfway in the direction opposite to the predetermined direction (rotated 180 degrees) and wound in this state. The hose 64 may be pulled and removed. When the rotation operation handle 90 is rotated in this way, the central portion of the hose 64 is hung on the auxiliary winding shaft 86 and a load is applied, so that the auxiliary winding shaft 86 (second rotating shaft 74) is applied. Thus, the main winding shaft 78 (first rotating shaft 72) and the contact member 76 are rotated relative to each other, and the second contact portion 82 of the contact member 76 becomes the secondary winding shaft 86 as shown in FIG. It will be in the 2nd state which contacts. In this second state, as easily understood by comparison with FIG. 6, the outer circumference circles of the main winding shaft 78 and the sub winding shaft 86 are smaller than those in the first state. A gap is created in the central portion of the wound hose 64 and is somewhat loosened, so that the wound hose 64 can be easily detached from the main winding shaft 78 and the secondary winding shaft 86.
