- the present invention relates to a magnet type chip conveyor. More specifically, the present invention relates to a magnetic chip conveyor that prevents long chips such as a lathe from staying.
- Magnet type chip conveyors are known that allow chips to fall out (Patent Document 1, Patent Document 2, Patent Document 3). Such a magnetic chip conveyor is preferable because chips generated during processing can be separated and discharged from the coolant, so that the coolant is not taken out to the outside.
- the conventional magnetic chip conveyor when long chips such as lathe chips are generated, attracts both ends of the endless chain at the same time by the magnets on the upstream and downstream sides of the endless chain.
- the frictional force between the surface and the chip, the gravity of the chip, etc. may be balanced with a certain probability. In such a case, there is a problem that long chips do not move on the surface of the nonmagnetic plate and long chips stay on the surface of the nonmagnetic plate.

- the plate 4 is a chip discharge path and a cover for the endless chain 5.
- the magnetic chips that fall along with the machining liquid on the surface of the horizontal portion 41 of the plate 4 are attracted by the permanent magnets 61, 62, and 63 of the endless chain 5 disposed on the back surface of the plate 4.
- the chips move to the left shown in FIG. 1 and are separated by causing the coolant to flow down by gravity at the inclined portion 42.
