説明
The purpose of bale opener is to open the bale to fine and uniform tufts.Therefore, the way how to open the bale influences strongly the mean value and the distribution of tuft weight.<BR>In the present paper, the difference between theoretical and practical tuft weight is investigated, and one theoretical and two experimental models to simulate real bale opening process are presented.Finally the effectivity of a locus analysis and two models to explain the opening mechanism are examined.<BR>The results can be summarized as follows : <BR>1. Mean tuft weight investigated at a opening process in commercial mills depends on a production rate of tuft and increases proportionally with the production rate.<BR>2. There is a big difference between theoretical mean tuft weight calculated from opening conditions including production rate and practical mean tuft weight collected from actual opening process in the mills.It means that the opener spike plucks only one tuft approximately at its 15∼30 times strikes.<BR>3. Ideal opening curve of opener's spike tip for bales is theoretically indicated as a trochoid curve and it can be classified into down-cut opening (D.C.O.) curve and up-cut opening (U.C.O.) curve.<BR>4. It is suggested by the two experimental models that the size of tufts opened with D.C.O.are smaller and more uniform because of the smoother surface of bale formed by the strike of D.C.O.than those of U.C.O..<BR>5. The mechanism to cause the miss swing can be qualitatively explained by experimental observations by the two experimental models.
