<p>PROBLEM TO BE SOLVED: To provide a hose take-up device that can accurately detect a pull-out amount of a hose without effect on a state of dirt of the hose and a state of stretching force of the hose, by detecting the pull-out amount of the hose from rotation of a hose reel.SOLUTION: A hose take-up device comprises: rotation amount detecting means 20 that detects a rotation amount and a rotation direction of a hose reel 10; memorizing means 30 that memorizes association data between a rotation amount of a hose 1 from an origin position relative to a hose reel 10 and a pull-out amount of the hose 1 from the origin position relative to the hose reel 10, according to a hose length and a hose diameter; inputting means 40 that inputs hose-specification information that specifies the hose length and the hose diameter; calculating means 50 that calculates the pull-out amount from the rotation amount detected by the rotation amount detecting means 20 by using the association data to be determined by the hose specification information inputted by the inputting means 40; and displaying means 60 that displays the pull-out amount calculated by the calculating means 50.</p> |
