。Next, a mode of using the present invention shown in FIG. 1 will be explained with reference to FIG.
Based on the relationship between the amount of magnetic flux and the amount of steel plates to be lifted, the device 6 calculates the required amount of magnetic flux corresponding to the required amount of steel plates to be lifted, and the required amount of magnetic flux is calculated! 8 (a). Next, the lifting electromagnet 2 is lifted (port), and the amount of steel plate lifted is determined based on the plate thickness determination result of the device 5 (c).First, the device 7 determines the status of the lifted amount (excess, success, shortage). (2) If the suspension is insufficient, the device 7 changes the magnetic flux command value to the device 8. If the suspension is insufficient, the suspension electromagnet 2 is placed on the floor (e). If the hanging is done correctly, strong excitation is applied to make it difficult for the attracted boards to fall (see below). In case of excessive lifting, use some means to separate the plates. (G) Fig. 3 shows a method of calculating the magnetic flux command value for separating unnecessary plates when lifting the plates.
吊り上げたい板の総板厚をｔｎ、総重量をＷｎ、吊り上
げたくない板の総板厚をｔｎヤ１．総重量をＷｎや１と
する。それぞれに働く吸着力をＦｎ。The total thickness of the boards you want to lift is tn, the total weight is Wn, and the total thickness of the boards you don't want to lift is tn. Let the total weight be Wn or 1. The adsorption force acting on each is Fn.
Ｆｎゆ１とすると、電磁石の総磁束Φに対して、Ｆｎ＜
Φ２
Ｆｎ＋１にΦ３
であり、第３図のような放物線の特性曲線を描く。If FnY1, then Fn<
Φ2 Fn+1 and Φ3, and a parabolic characteristic curve as shown in FIG. 3 is drawn.
いま、吊り上げたい板の吸着力Ｆｎが総重量Ｗｎと等し

量Ｗｎ＋１に等しくなる磁束値をΦＬとする。ΦくΦＳ
の範囲では、吊り上げたい板に働く吸着力Ｆｎが重量を
下まわるので、必要な板を吸着できない、またΦしくΦ
では、吊り上げたくない板に働く吸着力Ｆｎゆ１が重量
Ｗｎや１を上まわるため不必要な板も吸着する。Let ΦS be the magnetic flux value at which the attraction force Fn of the board to be lifted is equal to the total weight Wn, and ΦL be the magnetic flux value at which the attraction force of the board not to be lifted is equal to the weight Wn+1. ΦkuΦS
In the range of
In this case, since the suction force FnY1 acting on the board that is not desired to be lifted exceeds the weight WnY1, unnecessary boards are also attracted.
ΦｓくΦくΦの範囲では、Ｆｎ＞Ｗｎ、Ｆｎ＋ｔ ＜Ｗ
ｎ４．１となり、必要な板だけを吊り上げることが可能
である。In the range of Φs×Φ×Φ, Fn>Wn, Fn+t<W
n4.1, and it is possible to lift only the necessary boards.
磁束の設定方法としては、設定初期値としてΦＬを与え
、分離できなかった場合には、ΦｓくΦくΦ、の範囲を
いくつかに分離し、ΦＳに至るまで順次磁束指令値とす
る。これを装置７が行なう。As for the magnetic flux setting method, ΦL is given as the initial setting value, and if separation is not possible, the range of Φs, Φ, and Φ is divided into several parts, and the magnetic flux command values are set sequentially until ΦS is reached. This is done by device 7.
以上の通り本発明によれば、吊り上げ枚数を所定量に調
