Description

[Detailed description of the invention]

[0001]

The present invention separates chips and cutting water or cutting oil generated during cutting by a cutting machine such as a lathe using cutting water, and returns the cutting water or cutting oil to a cutting tank. The present invention relates to a chip conveyor for discharging chips outside the facility.

[0002]

2. Description of the Related Art First, a conventional chip conveyor 101 will be described with reference to FIG.

A cubic cutting tank 110 having a hollow inside and a chip conveyor 101 placed above the cutting tank 110 are housed inside cutting equipment 120 such as a lathe, and are provided with an endless load transport belt 103 driven by a drive motor 115. Frames 117 are installed along the rotating path of the endless load transport belt 103 in both end directions. Then, the frame 117 along the driven endless load transport belt 103 located on the opposite side to the drive side of the endless load transport belt 103.
The three cutting water discharge ports 109 are opened at the center position of the vertical width of the driven portion 121 along the traveling direction of the endless load transport zone 103. In its normal state, when performing cutting using cutting water or cutting oil in the cutting equipment 120, on the other hand, chips of a certain size or more generated by cutting,
It is dropped and transported on the rotating endless load transport belt 103, and is discharged from the chip discharge port 106 to the chip box 113.
On the other hand, cutting water or cutting oil that is used in the cutting equipment 120 and contains small chips at the time of cutting falls from the endless load transport zone 103 onto the upper surface of the front cover, and the frame 1
From 17, the cutting water is returned from the cutting water discharge port 109 to the cutting tank 110, and the cutting water or cutting oil in the cutting tank 110 is used again for cutting by a cutting pump or the like.

[0004]

In using the chip conveyor 101 as described above, the chip conveyor 10 is used.
Since the first cutting water discharge port 109 is opened without providing a chip filter, cutting water or cutting oil containing chips is directly discharged from the cutting water discharge port 109 to the cutting tank 110. Chips settle. Since the settling of the chips continues during the processing by the cutting equipment 120, if the chips are not removed, the settled chips will be removed from the cutting tank 1.
10, reducing the actual tank capacity of the cutting tank 110
Reduce the amount of cutting water or cutting oil that can enter. Then, there is a possibility that dimensional defects may occur due to an increase in the temperature of the cutting water or cutting oil, and processing defects may occur due to a decrease in the amount of cutting water or cutting oil discharged. Alternatively, the settled chips hinder the smooth flow of the cutting water or cutting oil in the cutting tank 110, and the cutting water or the cutting oil overflows from the cutting tank 110 to stain the floor.

[0005] For this reason, it is necessary to carry out a chip removal operation on a daily basis. However, in order to remove chips, first, the chip conveyor 101 is pulled out of the cutting equipment 120,
Next, a chip removing operation of the cutting tank 110 is performed in a space regulated by the cutting equipment 120, and after the operation is completed, the chip conveyor 101 is stored in the cutting equipment 120 again. Thus, there is a drawback that the periodic chip removing operation is complicated and requires a long time.

Accordingly, an object of the present invention is to provide a chip conveyor which solves the above-mentioned drawbacks, simplifies daily chip removing work, and has a high chip removing workability.

[0007]

SUMMARY OF THE INVENTION An endless load transport belt comprising an annular belt driven and curved by a drive motor, and a curved portion at a lower end along the endless load transport belt, the lower side of the endless load transport belt. In the chip conveyor equipped with the front cover attached to the above, a cutting water discharge port is opened at an appropriate position near the curved portion of the front cover, and outside the cutting water discharge port, separate from the front cover from cutting water or cutting oil. A removable chip filter was installed to remove the chips.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a configuration of a chip conveyor 1 according to an embodiment of the present invention, in which a chip conveyor 1 and a cutting tank 10 are housed in a cutting equipment 20, and the chip conveyor 1 is composed of two left and right connected chips. It is supported by the legs 16 and the cutting tank 10. Then, as shown in FIG. 2, a chip box 13 having an upper opening is provided below the chip discharge port 6 of the chip conveyor 1. Further, the chip conveyor 1 is curved along an endless load transporting belt 3 composed of an annular belt 2 driven by a drive motor 15 and a lower side of the endless load transporting belt 3, and is installed at both ends of the endless load transporting belt 3. Front cover 4 connected to S-shaped frame 17
Then, the upper part of the endless load transporting belt 3 in the range accommodated in the cutting equipment 20 is exposed, and the upper part of the endless load transporting belt 3 is covered in a V-shape in a range not accommodated in the cutting equipment 20 and connected to the frame 17. And the driven endless load transporting belt 3 located opposite to the driving side of the endless load transporting belt 3 driven by the drive motor 15.
And a tail cover 8 connected to the frame 17 in a semicircular shape. A cutting water discharge port 9 is opened near the curved portion 11 located at the lower end of the above-described front cover 4,
A detachable chip filter 5 in which a mesh 24 is adhered to a frame 23 provided with a semicircular handle 22 as shown in FIG. 3 outside the cutting water discharge port 9 is installed separately from the front cover 4.

[0010] The chip conveyor 1 configured as described above
Will be described with reference to FIGS. 1 to 3. When cutting is performed by the cutting equipment 20, the chips generated by the cutting and the cutting water or cutting oil used at the time of the cutting directly fall onto the endless load carrying belt 3 during rotation. Then, chips of a certain size or more are discharged from the chip discharge port 6 to the chip box 13 by the endless load transporting belt 3 rotating in the transport direction indicated by the arrow A in FIG. 2, but as shown in FIG. Cutting water or cutting oil containing small chips falls from the endless load transport zone 3 onto the upper surface of the front cover 4, flows on the upper surface of the front cover 4, and is discharged from the cutting water discharge port 9. The cutting water discharged from the cutting water discharge port 9 and containing the chips, the chips are removed by the chip filter 5 and returned to the cutting tank 10. If the cutting process is continued, the chips are piled up on the chip filter 5, and after the chip filter 5 is removed and cleaned in a normal state where the chips are accumulated to some extent, the chip filter 5 is removed from the cutting tank outside the cutting water discharge port 9. The periodic chip removal operation is completed by mounting the chip on the chip 10.

According to the above embodiment, chips of cutting water or cutting oil discharged from the chip conveyor can be removed, and the removed chips can be entirely deposited on the chip filter.

[0012]

[Effect of the Invention] As described above, according to the present invention, a cutting water discharge port is opened at an appropriate position near the curved portion of the front cover of the chip conveyor, and a chip filter that can be detached separately from the front cover is installed. In addition, the periodic chip removal operation does not require a complicated operation such as taking out the chip conveyor from the cutting equipment. Therefore, after removing and cleaning the chip filter, the periodic chip removal operation is completed only by mounting the chip filter on the cutting tank. Therefore, it is possible to improve work efficiency.
