<p>PROBLEM TO BE SOLVED: To enable measurement without using a load cell, and to accurately measure the weight of a roll bale even if an angle of a hydraulic cylinder changes according to the lifting of the roll bale.SOLUTION: A wrapping machine with a weight measuring function is provided with a bale supporting base on which a roll bale is placed; a lift-up mechanism 5 for lifting up the bale supporting base by a hydraulic cylinder 52 while raising a link member 51 intersecting in an X-shape; and weight measuring means for measuring the weight by measuring hydraulic pressure within a range in which an axial tilting angle of the hydraulic cylinder 52 is 45 degrees or less. In the case of measuring hydraulic pressure, lift-up is stopped within a range in which a tilting angle of the hydraulic cylinder 52 is 45 degrees or less, a bottom side hydraulic chamber is shut off by a shutoff valve, a rod side hydraulic chamber is opened, the hydraulic pressure is measured after a lapse of a certain time, and the weight is measured by the measured value.</p> |
