Here, when the mesh plate 610 is coupled to the mesh support rod 630 of the mesh drum 600, the mesh plate 610 may be bundled and coupled, but it is preferable to simply combine the spot plate by spot welding for durability.

In addition, as described above, in the present invention, the coolant and the microchip fall from the input unit 110 of the frame 100 so that the coolant is stored and recovered in the coolant tank 400. ) Rotates continuously and collects only the microchips included in the cleats by the mesh play 610 of the gear shape, and transfers the same to the transfer belt 300. Therefore, since the coolant of the coolant tank 400 is discharged without staying for a long time, the contamination of the clant is reduced and the correction is possible, so that the coolant can be used for a long time, and the contamination of the coolant and the coolant is included in the coolant. It is possible to prevent malfunction or failure of the chip conveyor device due to the circulation of fine chips.

On the other hand, when the mesh drum 600 is rotated to transfer the microchips to the upper surface of the conveyance belt 300, most of them fall by their own weight, but the extremely fine powder chips are trapped and trapped in the mesh plate 610 Emissions can be difficult. To solve this problem, as shown in FIGS. 10 and 11, the injection nozzle 800 is installed.

The injection nozzle 800 is installed above the mesh drum 600, and the microchips collected from the coolant tank 400 fall on the inner circumferential surface of the mesh plate 600 of the mesh drum 600 to drop the transfer belt. Compressed air is injected toward the inside from the outer peripheral surface of the mesh plate 610 of the mesh drum 600 to be transmitted to.

Second, a plurality of spray nozzles 800 are installed above the mesh drum 600 in a line along the front and rear longitudinal directions to spray compressed air through the respective spray nozzles 800.

Therefore, the injection nozzle 800 injects compressed air toward the inside from the outer circumferential surface of the mesh plate 610 installed in the mesh drum 600, the fine chips collected in the mesh plate 610 is the injection nozzle 800 Compressed air is injected into the falling to the upper surface of the conveyance belt 300 is transmitted and is discharged to the lower portion of the open discharge portion 130 of the frame 100.

The present invention can be applied not only to the hinge type and apron transfer belt 300, but also to a scraper type belt.

As shown in FIGS. 20 to 22, the frame 100 further includes a scraper plate 900 installed between upper and lower portions on the track of the transport belt running in an endless track therein. In addition, the conveying belts are spaced apart from each other, and are supplied from the top of the inlet of the frame 100 to scratch the chips accumulated on the upper surface of the scraper plate 900 to the lower portion of the discharge portion 130 of the frame 100 A scraper belt 910 to which a plurality of scrapers 920 to be discharged are coupled may be applied.

That is, a plurality of the scraper 920 is installed on the scraper belt 910, each of which is formed spaced apart from each other at regular intervals so that the chip supplied from the top of the inlet of the frame 100 of the scraper plate 900 Stacked on the upper surface, the scraper 920 scrapes the chips stacked on the scraper plate 900 and discharges the chips to the lower portion of the discharge unit 130 of the frame 100.

In addition, when discharging the chip into the scraper belt 910, the coolant is a coolant dropping hole 930 vertically penetrating the front of the scraper plate 900, that is, below the input portion 110 of the frame 100. It is installed to drop the coolant supplied to the input unit 110 of the frame 100 to be stored and recovered in the coolant tank 400.

 In addition, the coolant falling through the coolant dropping hole 930 of the scraper plate 900 is also dropped in order to be stored and recovered in the coolant tank 400 because the fine chips of the powder are joined and dropped as described above. The microchips contained in the coolant must be discharged.

The scraper belt (910) type of the chip conveyor device for discharging the fine chips contained in the coolant, as described above, when the mesh drum 600 is rotated in accordance with the drive of the motor 520 the mesh drum The coolant, which is fluid, remains in the coolant tank 400 as it is by the mesh plate 610 of the mesh provided in the shape of a gear, and only the fine chips are collected in the mesh plate 610. The microchips collected in the mesh plate 610 are rotated and moved to an upper portion of the scraper belt 910 according to the rotation of the mesh drum 600 to fall on an upper surface of the scraper belt 910 and the scraper belt 910. ) Is discharged below the discharge unit 130 of the frame 100 to discharge the fine chips. Other advantages are the same as described in the hinge type transfer belt.

In addition, as described above, the chip conveyor apparatus according to the present invention can rotate the direction of rotation of the conveyance belt from the inlet of the frame to the discharge direction, that is, in the same rotational direction as the general hinge type chip conveyor. It can be applied regardless.

As described above, the chip conveyor apparatus according to the present invention is moved to the coolant tank by mixing with the coolant moved to the coolant tank to recover the coolant tank as well as the linear chips or the massive chips regardless of the type of the conveying belt. The fine chips are introduced into the coolant tank and are collected in the mesh plate of the mesh drum provided to be submerged in the coolant tank, and are fined from the coolant through the rotating mesh drum and mesh plate. After the chip is filtered and transferred to the upper surface of the conveying belt, it can be easily transported and discharged to the rear of the frame, thereby greatly reducing the amount of chips lost, preventing failure, and achieving coolant integrity.

Furthermore, the fine chips accumulated in the mesh plate are transferred to the upper surface of the conveyance belt through the injection nozzle for injecting compressed air, so that the chips can be easily discharged to the rear lower part of the frame, thereby achieving more efficient chip discharge.
