PURPOSE:To moor a can body at predetermined laying depth, by converting the hydraulic pressure through a piston into the axial movement of a stopper chip then regulating the movement of the stopper chip and a rolling chip. CONSTITUTION:The hydraulic pressure variation due to the sinking of an engaging device 2 is converted into the axial movement of a piston 9. While the feeding amount of a mooring rope 4 due to the floating of a can body is inverted through the locus of a reduction gear mechanism 21 and a groove 17' into the axial movement of a rolling chip 17a to be engaged in said groove. A stopper chip 13 will move on a fixed shaft 27 and a movable shaft 26 where the length between the starting position of the stopper chip 13 on the fixed shaft 27 and the movable shaft 26 is set to correspond with the laying depth. Since the length of the movable shaft 26 is shorter by the regulating depth of the fixed shaft 27, the can body will float. Consequently the can body is moored at predetermined laying depth. |
