【考案が解決しようとする課題】[Problem that the idea aims to solve]

上記の従来構成では主磁路dの他に、矢印d3 で示されるように、主磁路dの 側部から分岐して上端の被搬送物aにまで達することなしに、磁石cへ流れ込む バイパス磁路が多数発生し、主磁路dにおいて大きい磁力のロスを生じる。また 磁石cの磁力が強過ぎると、被搬送物aが下方に引っ張られ過ぎて反りを生じ、 または弱過ぎると、被搬送物aがベルトb上で安定せず変位したりする。そこで 磁力の微調整が必要となるが、これは通常磁石cの大きさや種類を変えるなどし て行なっている。磁石cはセラミックで作られることが多いので、作成に手間が かかり煩雑な作業である。 In the above conventional configuration, in addition to the main magnetic path d, as shown by the arrow d3, the main magnetic path d is It branches from the side and flows into the magnet c without reaching the conveyed object a at the upper end. A large number of bypass magnetic paths are generated, resulting in a large loss of magnetic force in the main magnetic path d. Also If the magnetic force of magnet c is too strong, the transported object a will be pulled downward too much, causing warping. Alternatively, if it is too weak, the conveyed object a will become unstable on the belt b and may be displaced. Therefore Fine adjustment of the magnetic force is required, but this is usually done by changing the size or type of magnet c. is being carried out. Magnet c is often made of ceramic, so it takes time and effort to create. This is a time-consuming and complicated task.

【0004】 そこで本考案の目的は、被搬送物に及ぶ磁力の微調整を容易にし、しかも安価 に提供することにある。0004 Therefore, the purpose of this invention is to make it easy to fine-tune the magnetic force exerted on the conveyed object, and to make it inexpensive. The aim is to provide the following.
