Description

[Detailed Description of the Invention] The present invention relates to a winder for a cloth water supply hose used for firefighting or watering.

When storing this type of hose, especially long hoses such as fire hoses, after being used for water supply, drain and dry the hoses, then fold them back at the center of their length and stack them in double layers. While compressing the hoses in a flat state, the hoses are sequentially rolled up by a hose winder starting from the center folded portion to form a bundle having a predetermined diameter. By the way, when two layers of flattened hose are rolled into a bundle, the inner hose being wound will be compressed and the outer hose will be under tension, so it is difficult to use the winder. If the bundle is wound continuously as it is, the problem arises that the contact surfaces between the inner hose and the outer hose are not properly brought into close contact with each other, resulting in a bundle that is large in diameter and lacks tightness. Therefore, in conventional hose winding, instead of winding the hose continuously, the winding is temporarily stopped midway and corrections are made, or the worker continuously pulls on the inner hose while separately winding the hose. The winding must be done by several workers rotating the winder, which requires time and skill to wind the entire length of the hose, and it is difficult for one worker to wind the hose. The problem was that it could not be done efficiently.

The purpose of this project is to solve these problems in hose winding work, and to provide a hose winder that allows winding to be carried out easily, properly, and efficiently without requiring any skill. It is something.
In addition, in order to achieve the above-mentioned purpose, the winder according to the present invention has a winding frame at one end of the pedestal, and a pressure roller at the other end for compressing the hose flat with spring pressure. A roller-shaped hose is provided between the take-up frame and the pressure roller at a position approximately at the same height as the winding shaft of the take-up frame to give a bending angle to the hose transitioning from the pressure roller to the take-up frame. It is characterized by:

Next, the present invention will be explained with reference to the illustrated embodiment.
As shown in FIG. 1, this winder consists of a winding frame 2 provided at one end of a long and narrow base 1, a pressure roller 3 for overlapping hoses provided at the other end of the base 1, and a It consists of a hose guide 4 provided in the center.

As shown in FIGS. 2 and 3, the winding frame 2 has a support 5 erected on one edge of one end of the pedestal 1.
A rotating shaft 6 bearing at the upper end and supported for rotation by a handle 7 located outside the pedestal 1 is aligned with one side edge of the hose 10 provided on the rotating shaft 6 above the pedestal 1. It consists of a cross-shaped frame piece 8 for the rotational shaft 6, and two parallel winding shafts 9 provided at the center of the frame piece 8 so as to sandwich both sides of the extension line P of the rotating shaft 6. As shown in FIG. 3, this winding shaft 9 is a cylindrical fitting portion supported parallel to a pair of shafts 9b projecting from the frame piece 8 by a connecting rod 9c parallel to the frame piece 8. 9a is removably fitted.

The pinching roller 3 provided at the other end of the pedestal 1 is provided at a portion of the winding frame 2 that is separated by a length L that is approximately twice the height H of the winding frame 9, and is located at a portion of the periphery. It consists of a lower roller 3b which is pivotally supported within the pedestal 1 so as to be exposed on the pedestal 1, and an upper roller 3a which is placed above the lower roller 3b and is in pressure contact with the roller. This upper roller 3a is the arm 12
The other end of the arm 12 is pivotally supported by the upper end of a column 11 erected on one side edge of the base 1. Further, this arm 12 is configured such that an intermediate connecting portion 13 is pulled by a spring 14 provided on the pedestal 1 near the winding frame support 5, so that the upper roller 3a is connected to the lower roller via the arm 12. It is adapted to come into pressure contact with spring pressure being applied to 3b. A lever 15 is provided at the tip of the arm 12, and this lever 15 allows the spring 14 to be
Pull up the arm 12 against the elasticity of the hose 10.
After placing the hose between the upper and lower rollers 3a and 3b, if the lever 15 is returned, the hose 10 will be flattened and compressed between both rollers. Further, a pair of left and right guide plates 16 are provided on the pedestal 1 in front of the pinching roller 3 for regulating both side lines of the hose 10 to a fixed position. On the other hand, hose guide 4
is provided on a support 17 erected at an intermediate portion between the pinching roller 3 and the winding frame 2. The hose guide 4 consists of a pair of guide plates 18 similar to the guide plates 16 fixed on the support column 17, and a roller 19 provided between the guide plates 18. Further, the position where this hose guide 4 is provided is preferably a little more than about half of the distance L between the winding frame 2 and the pinch roller 3, and the pinch roller 3
The height h is located at a portion of the winding frame 2 that is approximately at the same height as the winding shaft 9.

The hose winder according to the present invention has the above-mentioned structure, and when winding the hose, the upper roller 3a of the pressure roller 3 is separated from the lower roller 3b by pulling up the arm 12, and the hose is folded back at the center of the entire length to form two layers. Place the tip of the hose 10 on both rollers 3.
After properly arranging the hose 10 between the hoses 10a and 3b via the guide plate 16, the upper roller 3a is returned and the elasticity of the spring 14 compresses and compresses the hose 10 into a flat shape. In this state, pull the tip of the hose 10 at the folded part,
It is connected to the winding shaft 9 of the winding frame 2 via the hose guide 10. To connect to the winding shaft 9, as shown in FIG. 4, the tip of the hose 10 is introduced from the underside of the shaft 9 and entwined with the cylindrical fitting portion 9a. After the hose 10 is set in this manner, the winding frame 2 is rotated by the handle 7, and winding is continued as shown in FIG. After winding is completed,
The cylindrical fitting part 9a of the winding shaft 9 is fixed to the fixed shaft 9.
b to remove the hose bundle 10A from the winding frame 2.

The winder according to the present invention includes a pressure roller 3 provided on the other end surface of the pedestal 1 separated by a length L that is approximately twice the height H of the winding shaft 9 in the winding frame 2, and Since the hose guide 4 is provided between the frame 2 and the pressure roller 3 and has a height h that is approximately the same as the winding frame winding shaft 9,
The two-ply hose 10 that has been flattened by the pressure roller 3 is tightened at three points: the pressure roller 3, the hose guide 4, and the winding shaft 9, and the hose 10
is supported at a bending angle B by the upper end roller 19 of the hose guide 4 above the line connecting the pinching roller 3 and the winding shaft 9. This bending angle B is the direction in which the folded end of the hose 10 is bent when the folded end of the hose 10 is wrapped from below the winding shaft 9 as shown in FIG. 4 (the direction of the counterclockwise hand in the drawing in FIG. 4).
Since the direction is opposite to that of the outer hose 10, the two-ply hose 10 at the winding shaft 9 is
A is pulled and the inner hose 10b is compressed, whereas in the hose guide 4, the outer hose 10a is on the lower side and is compressed, and the inner hose 10b is on the upper side and is subjected to tension. It happens. In other words, while the two-ply hose 10 is moved from the pinch roller 3 to the take-up frame 2, one hose 10a is compressed and the other hose 10b is tensioned at the hose guide 4, and the next hose 10a is moved to the take-up frame 2. At this section, each hose 10a, 10b is subjected to tension and compression in a direction opposite to that at the hose guide 4 section. Therefore, a double layered hose 10
When hoses a and 10b are simultaneously wound up by the take-up frame 2, the hose guide 4, which is a preliminary step, applies the compression previously applied to one hose 10a and the compression applied to the other hose 10b. The applied tension is canceled out by the tension generated in one hose 10a and the compression generated in the other hose 10b at the next stage of the winding frame 2, and each hose 10a, 10b is wound up. It is wound up with a degree of tension that does not loosen against the frame 2.

In addition, each hose 10a, 10b is connected to a pinch roller 3 and a hose guide 4 before being wound onto the winding frame 2.
It is polymerized flatly at two points, and the tension associated with the predetermined bending angle is applied at these two points, so
The tension of the hose 10 does not loosen before being wound onto the winding frame 2, and therefore winding can be performed with an appropriate bundle tension being applied. Note that the bending angle b of the hose 10 by the hose guide 4 slightly changes between the initial stage of winding as shown in FIG. 4 and the final stage of winding as shown in FIG. Since there is no change, winding can be performed without any problem.

In addition, in the pinching roller 3, the upper roller 3a is connected to the support 11.
The lower roller 3 is supported by the arm 12 which is pivotally supported by
Since it can be opened and closed in the vertical direction in parallel to b, the hose 10 can be easily compressed and released. Furthermore, since the winding frame 2 has a winding shaft 9 consisting of a pair of parallel shafts 9b detachably attached to the winding shaft 2, the bundle can be removed extremely easily after winding is completed. be able to. Therefore, this winder has the effect that tight winding, which conventionally could not be done by one operator, can be done appropriately and efficiently.
