CONSTITUTION:When a drum 20 is rotated in the arrow A direction by a handle 25, a hose 5 is wound on a cylinder body 22 from one end to the other end in the single layer spiral state, and a guiding means 30 is moved toward the other end and as it comes near to the other end, it extends a coil spring 44 and increases returning force. And when it reaches the other end and forms the first streak of the second layer, it eliminates resistance to the returning force working in the inward direction of the cylinder body 22, shifts a guiding cylinder in the same direction and surely executes returning. In this way, winding the hose along a flange 21b several times is prevented, and the hose can be wound easily only by rotating the cylinder body 22.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application IF) The present invention relates to a device for winding and unwinding flexible long materials such as vinyl hoses, electric cords, ropes, etc. This invention relates to a winding device for a flexible long object which prevents multiple windings at the terminal end and allows smooth winding.

(Prior Art) As a conventional winding device for flexible long objects, a watering device that winds up a vinyl hose used for watering trees and lawns around a drum is well known. Some types have spiral grooves formed on the winding surface of the drum in order to spirally wind the drum onto the drum.

(Problems to be Solved by the Invention) However, in a winding device in which a spiral groove is formed on the winding surface, the first layer is wound neatly along the spiral groove, but the second and third layers... At the turn-back point at the end of the drum, if the drum is not guided by hand, it will often wind around the flange in multiple layers. especially,
When winding is carried out by one person, it is very tedious to rotate the drum with one hand and use the other hand to successfully guide the next spiral winding at the turning point.

The present invention has been made in view of the above, and has a flexible length that allows long flexible objects such as vinyl hoses to be neatly arranged on a drum and wound up in many layers by simply rotating the drum. The purpose of the present invention is to provide a winding device for shaku articles.
