The take-up roll has a holding shaft 34 and a plurality of winding rolls provided at equal intervals around the holding shaft 33. Has a thin steel pipe 35. As shown in FIGS. 4 and 5, a holding frame 36 extends from the end of the boom 7 in the extending direction thereof.
A suspension frame 24 for detachably holding the take-up core 23 is attached to a distal end portion of the holding frame 36. The suspension frame 24 has a central portion in the longitudinal direction detachably attached to a distal end portion of the holding frame 36 via a pin 37 or the like. The suspension frame 24 is formed with clamp portions 38 and 39 that are suspended downward from both ends.
These clamp portions 38 and 39 move in the longitudinal direction along the suspension frame 24 and engage with the winding core 23 in a detachable manner. For example, the moving parts 24a such as a chain and a sprocket, a rack and pinion, or a hydraulic cylinder move the clans 38 and 39 by an equal distance. One of the clamps 38, 39 is provided with sheet winding means 25 for driving the winding core 23 to rotate. The sheet winding means 25 is constituted by a drive motor for rotating the winding core 23 forward and reverse. On the suspension frame 24, there is provided a turning means 26 for turning the suspension frame 24 in the horizontal direction. The turning means 26 is provided with a turning shaft 41 extending upward from an intermediate portion of the suspension frame 24. Is constituted by a turning drive motor for turning the motor horizontally. In this embodiment, since the sheet is hung in the direction crossing the pile 8, the suspension frame 24 is turned according to the turning angle of the boom 7 so that the winding core 23 is always kept parallel to the longitudinal direction of the pile 8. Will be adjusted. Similarly, as shown in FIG. 5, at the tip of the boom 7, an up-and-down means 27 is provided to horizontally hold the take-up core 23 which tilts up and down due to the up and down movement of the boom 7. The undulating means 27 is constituted by a hoisting device or a hydraulic cylinder for raising and lowering the holding frame 36 in the vertical direction. In FIG. 1, reference numeral 22c denotes a take-up sheet stored on or beside the track bed 42 of the stacker 2.
