Fig. 4 is a perspective view showing the screen filter of Fig. 1; The direction indicated by the arrows and the direction opposite thereto are all considered to be in the same direction on the drawings.

Referring to Figs. 1 to 4, a chip processing apparatus 10 for a machine tool may include a conveyor 100, a screen filter 200, a chip collection box 300, and a coolant tank 400.

The conveyor 100 is installed on the chip belt 110 and the chip belt 110 for discharging a plurality of chips generated in the machine tool and protrudes in one direction. The conveyor 100 moves apart with the chip belt 110, And a plurality of chip scrapers 120 scraping off the chips on the bottom surface. The conveyor 100 may extend in a second direction D2 that intersects the first direction D1.

The chip belt 110 can be rotated endlessly by the belt motor 102. The chip belt 110 may receive the chips generated in the machine tool and discharge the chips to the chip outlet 106.

For example, the chip belt 110 may move along the second direction D2 to move the chips to the chip outlet 106. [ In addition, the chip belt 110 can be supported and moved by the chip roller 130.

In addition, each chip scraper 120 can extend in a first direction D1 and can scrape the chips to transport the chips to the chip outlet 106.

A chip collection box (not shown) for collecting the chips may be disposed below the chip outlet 106.

The screen filter 200 is installed at a discharge port 102 formed on the bottom surface of the conveyor 100 to constitute a part of the bottom surface of the conveyor 100 and to filter the coolant discharged from the discharge port 102 of the conveyor 100, can do.

As shown in FIG. 4, in the exemplary embodiments, the screen filter 200 may be a straight screen filter. For example, the screen filter 200 may include a plurality of filter columns 210 that define discharge slits 220.

Each of the filter columns 210 extends in a second direction D2, which is the direction of extension of the conveyor 100, and has an inverted triangular column shape, and may be spaced apart to define discharge slits 220. In addition, each exit slit 220 may be formed between adjacent filter columns 210.

The chip scraper 120 may move in a second direction D2 with one end adjacent to the inverted triangular columnar flat surface of the filter columns 210, (Not shown).

Accordingly, filter cleaning is automatically performed by the chip scrapers 120, which eliminates the need for frequent filter cleaning of the machine tool operator at the time of cutting.

Further, the discharge slits 220 are disposed on the bottom surface of the conveyor 100, not on the side of the conveyor 100, and the coolant can be discharged downward through the discharge slits 220 of the screen filter 200. Therefore, the chips are swept to the side of the conveyor by the flow of the cutting oil discharged through the discharge port formed on the side of the conventional conveyor, thereby blocking the filter formed at the discharge port on the side of the conveyor to prevent the cutting oil from overflowing from the conveyor.

The chip collection box 300 can temporarily collect chips in the form of powder that are disposed under the screen filter 200 and passed through the screen filter 200.

In the exemplary embodiments, the chip collection box 300 may have a box-shaped top open. For example, the chip collection box 300 includes a bottom 310 and a bottom 310 disposed below the outlet 102 of the conveyor 100 and extending laterally (in the direction Dl) of the conveyor 100 A sidewall portion 320 extending upward from the one side wall of the conveyor 100 and a discharge port 330 for discharging the cutting oil, which is disposed on the sidewall portion 320 and removed from the chips, to the coolant tank 400 ).

The discharge port 330 is disposed at an upper portion of the side wall portion 310 of the chip disposal box 300 to prevent the chips from being swept and flowed into the coolant pump by the flow of the coolant.

In the exemplary embodiments, the chip collection box 300 is detachably mounted on a coolant discharge tray (coolant discharge tray) disposed below the discharge port 102 of the conveyor 100 and communicated with the coolant tank 400 . The coolant discharge outlet may be installed on the lower surface of the conveyor 100 so as to surround the discharge port 102. The coolant discharge port can be formed integrally with the coolant tank 400. In this case, a part of the coolant tank 400 may be formed to extend to a lower portion of the discharge port 102 of the conveyor 100, thereby performing the function of the coolant discharge unit. Alternatively, the coolant discharge port may be formed in a tray structure separate from the coolant tank 400. In this case, the coolant discharge receiver may be welded to the lower surface of the conveyor 100 or fixedly installed by a coupling member.

Accordingly, in a state where the chip disposal box 300 is removed, the coolant discharged through the screen filter 200 formed in the discharge port 102 of the conveyor 100 is immediately introduced into the coolant discharge outlet, To the coolant tank 400 toward the side (D1 direction) of the coolant tank 400.

In addition, a bottom portion 310 and a side wall portion 320 of the chip disposal box 300 may be provided with a mesh (not shown) for filtering chips in the form of powder.

The coolant tank 400 may be disposed under the conveyor 100. That is, the bottom surface of the coolant tank 400 may be located lower than the conveyor 100. And can store the coolant that has been cut and discharged through the outlet 330 of the screen filter 200 and the chip collection box 300. For example, the coolant may be recirculated by the coolant pump 410 to the machine tool.

In the exemplary embodiments, the machine tool chip processing apparatus 10 is disposed below the collection box 300, and the chips in the form of a powder are stacked on the chip collection box 300, And may further include a magnet 500 that magnetically precipitates. For example, the magnet may include an electromagnet, a permanent magnet, and the like. When the magnet 500 is an electromagnet, when depositing the chips, a magnetic force is generated to easily precipitate the chips on the bottom surface of the chip collection box 300, and chips are formed on the bottom surface of the chip collection box 300 When a lot of chips are stacked and cleaned, it is possible to adjust the chip to reduce or eliminate the magnetic force so that stacked chips can be easily removed.

In addition, the chip collection box 300 may include a magnetic body or a non-magnetic body. For example, the chip collection box 300 may include a non-magnetic material such as plastic.

In addition, each discharge vessel 220 may be provided between adjacent filter columns 210.

One end of the chip scraper 120 may be in contact with the inverted triangular columnar flat surface of the filter columns 210 and a portion 610 of the chips accumulated on the flat surface may be scraped by the chip scrapers 120 I can get out. For example, a portion 610 of the chips may be chips having a relatively large size. A portion 610 of the scraped chips may be transported by the chip belt 110 to the chip outlet 106.

Accordingly, since the filter cleaning is automatically performed on the screen filter 200 by the chip scrapers 120, there is an advantage that frequent filter cleaning of the machine tool driver is not required at the time of processing the cutting water.

In addition, since the discharge slits 220 are provided on the bottom surface of the conveyor 100, a part of the chips 610 is swept by the flow of the cutting oil so that the chips 610 enter the chip collection box 300 without passing through the filter column 210 Can be prevented.

The chip collection box 300 may filter other portions 620 of the chips that are disposed under the screen filter 200 and that are not filtered in the screen filter 200. For example, another portion 620 of the chips may be chips in powder form.

The chip disposal box 300 has the discharge port 330 formed at the upper position of the side wall portion 320 so that the flow of the cutting fluid prevents the other portion 620 of the chips from being swept away into the coolant pump .

Further, the magnet 500 can effectively deposit another portion 620 of the chips on the chip disposal box 300, thereby separating the chip disposal box 300 and collecting the deposited chips simply.

Accordingly, the chips can be efficiently collected, the possibility of failure of the coolant pump 410 can be reduced, the number of filter cleaning operations can be reduced, and the work efficiency can be improved.
