タの２次側は折曲加工される板材自体である。Means for Solving the d0 Problem In order to achieve the above object, the plate material transfer device of the present invention comprises a primary side of a linear induction motor which is fixed to a table and moves the plate in a straight line or turns the plate, and which is disposed on the table. , a plurality of ball bearings that hold the plate material at a constant gap from the primary side iron core surface of the linear induction motor and support the plate material in a movable manner; and a turning device that includes a pivot shaft that comes into close contact with the plate material when the plate material is turned. This is what I composed. The secondary side of this linear induction motor is the plate itself to be bent.
０１作用
このリニア誘導モータ（以下ＬＩＭという）はデープル
に固定されたＬＩＭの１次側に対して、複数の球軸受に
よって、１次側と一定間隙に保持された板材が、２次側
となり、所謂平板状片側式１１Ｍを構成したものである
。したがって、このＬＩＭの１次側を、その移ｖＪ磁界
の方向が、板材の移送方向に一致するようにテーブルに
固定し、多相交流を供給すれば、板材は移！ＩＩＪ磁界
に追従して移送される。01 Effect In this linear induction motor (hereinafter referred to as LIM), the secondary side is a plate material held at a constant gap from the primary side by a plurality of ball bearings, with respect to the primary side of the LIM fixed to the dimple. This is a so-called flat plate-like one-sided type 11M. Therefore, if the primary side of this LIM is fixed to a table so that the direction of the moving vJ magnetic field matches the direction in which the plate is transported, and multiphase alternating current is supplied, the plate will move! It is transported following the IIJ magnetic field.
また、板材をＬＴＭの１次側の移動磁界の外側で旋回装
置の旋回軸に密着さゼ、ＬＩＭの１次側に多相交流を供
給すれば、板材は旋回軸を中心として旋回する。したが
って板材の折曲げ端部を変更することができる。In addition, if the plate material is brought into close contact with the rotation axis of the rotation device outside the moving magnetic field on the primary side of the LTM and a multiphase alternating current is supplied to the primary side of the LIM, the plate material will rotate around the rotation axis. Therefore, the bent end portion of the plate material can be changed.
板材が鉄等の磁性体の場合には、ＬＩＭの１次側鉄心と
板材の間に大きな吸引力が動くが、テーブルに適宜配設
された複数の球軸受により間隙が保持されるので、板材
が１次側鉄心と接触するようなことはない。When the plate material is a magnetic material such as iron, a large attraction force moves between the primary core of the LIM and the plate material, but since the gap is maintained by multiple ball bearings appropriately arranged on the table, the plate material There is no possibility that the steel will come into contact with the primary iron core.
一般にＬＩＭは自己冷ｆＪ１機能を持たないのでＤＦ（
使用時間率）が小さいが、このＬＩｆｖｌは板材に発生
する熱が、板材と共に持ち去られるので、ＤＦを大きく
することができる。Generally, LIM does not have self-cooling fJ1 function, so DF(
Although the usage time rate) is small, this LIfvl allows the heat generated in the plate material to be carried away with the plate material, so the DF can be increased.
また、この形式のしｉＭの推力は、スリップ１付近に最
大値があり、速度が大きくなると推力が小さくなるので
、制御が容易で板材を迅速に移送することができる。In addition, the thrust of this type of iM has a maximum value near slip 1, and as the speed increases, the thrust decreases, so it is easy to control and the plate material can be transported quickly.
