Description

[Detailed description of the invention] The present invention relates to a magnetic material conveying device, in which an inner cylinder in which a magnet is spirally wound is disposed inside an outer cylinder made of a non-magnetic material,
Due to the relative rotational movement between the outer cylinder and the inner cylinder, magnetic substances such as cutting chips and iron powder mixed in the machining cutting oil are adsorbed and separated on the outer periphery of the outer cylinder, and The present invention relates to a magnetic material conveying device that transports and removes magnetic materials along the same direction.

Conventionally, this type of magnetic material conveying device was disclosed in Japanese Patent Application Laid-Open No. 47-217
No. 50 and Japanese Patent Application Laid-Open No. 48-50482, the method directly scrapes off magnetic materials such as cutting chips and iron powder that are transferred along the outer circumference of the outer cylinder, so that they are transferred along with the magnetic materials and removed from the outer cylinder. The cutting oil that adhered to the outer periphery of the cylinder is also scraped off together with the magnetic material, resulting in a drawback that sufficient cutting oil cannot be recovered.

Furthermore, a centrifuge or the like must be used to separate the cutting oil scraped off together with the magnetic material from the magnetic material.

An object of the present invention is to eliminate the drawbacks of the above-mentioned prior art and to provide a magnetic material conveying device that can efficiently recover cutting oil.

In order to achieve the above object, the present invention does not directly scrape off magnetic materials such as cutting chips and iron powder from the outer cylinder that attracts and transfers them, but instead scrapes them off after they are transferred to a magnetized drum. .

An embodiment of the present invention will be described below with reference to the drawings.

As shown in Figure 1 and Figure 3, an outer cylinder 1 made of non-magnetic material
Both openings are provided with side plates 2 and 3.

An inner cylinder 4 is disposed inside the outer cylinder 1, and N and S magnets 5 and 6 having different polarities are alternately wound helically around the outer periphery of the inner cylinder 4.

The shaft 8 (8A) passes through the side plates 7, 7 of the inner cylinder 4.

8B), and one end 8A of the shaft 8 is fixed to the side plate 2r/
A gear 9 is mounted on the c-axis, and the other end 8B passes through the side plate 3 and is rotated by a drive mechanism such as a motor (not shown).

Therefore, the inner cylinder 4 around which the N and S magnets 5 and 6 are wound is rotated at a constant speed in the direction of the arrow in FIG. 2 via gears 9 and the like.

The left end side of the outer cylinder 1 (the side opposite to the side where the gear 9 is attached) is immersed in cutting oil 11 collected in a cutting oil tank 10 for a machine tool.

The right end side plate 3 is detachably fixed to a suitable fixing point 12π such as the base of a machine tool.

Figure 4 is a top view of the right end of Figure 1, and Figure 5 is a top view of the right end of Figure 1.
It is a sectional view along the Vv line of a figure.

As shown in FIGS. 4 and 5, a transfer outer cylinder 14 made of a non-magnetic material is provided adjacent to the outer cylinder 1VC corresponding to the magnet 5vc at the right end of the inner cylinder 4. 14 is additionally provided with a gear 15 that is rotated by a drive mechanism such as a motor (not shown).

Inside the outer cylinder 14, there is provided an inner cylinder 18 for transfer in which N and S magnets 16 and 17 are alternately arranged.

The axis of the inner cylinder 18 is parallel to the axis of the inner cylinder 4, and the axis 19 of the inner cylinder 18 is fixed to a fixed plate 20 fixed to the side plate 3.

21 is a raking board.

Next, the operation of the apparatus configured as described above will be explained.

The cutting oil is collected in the tank 10 with magnetic substances 13 such as cutting waste and iron powder generated by machining of machine tools mixed therein, but the recovered cutting oil 11 is cleaned by removing the magnetic substances 13 and reused. It is something that will be done.

The magnetic body 13 in the cutting oil 11 is attracted to and separated from the outer periphery of the non-magnetic outer cylinder 1 by the magnetic force of the magnets 6, 6 wound around the inner cylinder 4, and in this state, the inner cylinder 4 is rotated in the direction of the arrow shown in the figure. When driven, the magnet bodies 5 and 6 change their position in the circumferential direction due to the rotation of the inner cylinder 4, and since the magnet bodies 5 and 6 of different polarities are arranged in an alternate spiral in the inner cylinder 4, the above-mentioned Due to the circumferential positional fluctuations of the magnets 5 and 6 and the axial component of the magnetic lines of force along the spiral, the attracted magnetic body 13 moves around the outer circumference of the outer cylinder 1 as shown in FIG. The right end (diagonally upward) K of the outer cylinder 1 as seen in FIG.
Can be collected.

Since the magnetic force of the magnet bodies 16 and 1γ is stronger than the magnetic force of the magnet body 5, the magnetic body 13 gathered on the outer circumference of the right end is transferred to the transfer outer cylinder 14 which is rotating adjacently due to the magnetic force of the magnet bodies 16 and 17. Jump.

The magnetic body 13 that has been transferred to the outer cylinder 14 is transferred to the scraping plate 21 due to the rotation of the outer cylinder 14 and the magnetic force of the magnet bodies 16 and 17.

It is scraped off by the scraping board 21.

In this way, the magnetic material 13 is removed from the outer cylinder 1, and the cutting oil 11 is cleaned.

Note that the transfer outer cylinder 14 may rotate in the same direction as the inner cylinder 4 or may rotate in the opposite direction.

Alternatively, the outer transfer tube 14 may be fixed and the inner transfer tube 18 may be rotated, or both the outer transfer tube 14 and the inner transfer tube 18 may be rotated.

In this case, it is necessary to synchronize the inner tube 4 and the transfer inner tube 18 so that the magnet body 5 and the magnet body 16, 17 correspond to each other.

In addition, in the embodiment, the case where the axis of the transfer outer cylinder 14 is parallel to the axis of the transfer outer cylinder 1 is illustrated, but even if the axis is perpendicular to the outer cylinder 1, the transfer outer cylinder 14 may have magnetic properties. The body 13 may be attached at an angle that facilitates transfer.

As is clear from the above description, in this invention, magnetic substances such as cutting chips and iron powder are transferred from the outer cylinder that attracts and transfers them to the magnetized outer cylinder for transfer, and then scraped off, so that they are transferred together with the magnetic substances. The cutting oil that has adhered to the surface of the outer cylinder is left behind on the outer cylinder, and only the magnetic material is transferred to the transfer outer cylinder and removed.

Therefore, the magnetic material and the cutting oil are almost completely separated, and the dominant cutting oil is recovered.
