That is, when the workpiece P is input to the deoiling member 300, the opening / closing door 320 is opened, and when the deoiling member 300 is deoiled, the opening of the deoiling member 302 is opened. The opening / closing door 320 may be closed to prevent the processing oil and foreign substances generated during the de-oiling operation from flowing out.

Hereinafter, an operation of the method for deoiling a workpiece having the above-described configuration will be described with reference to FIGS. 1 to 18.

First, the operator supplies the workpiece P, which has been machined, to the workpiece transport conveyor 100 through a manual or automated machine. A workpiece conveying step (S100) in which a workpiece P continuously containing processing oil and foreign substances is moved from the top to the bottom as shown in FIG. 3 along the upper surface of the conveyor belt 110 of the workpiece conveying conveyor 100 Conduct.

When the workpiece P moves a certain distance according to the rotational movement of the conveying conveyor belt 110, the stop body 124 of the stop member 120 protrudes from the left to the right to move the conveying conveyor belt 110. A workpiece supply step (S110) of temporarily stopping the workpiece (P) moved by is performed.

In the step of supplying the workpiece (S110), the supply body 134 of the workpiece supply member 130 protrudes in the right direction while the workpiece P is stopped in the stop member 120.

After the stop body 124 returns to its original position, when a single workpiece P is located between the stop body 124 and the supply body 134, the stop body 124 protrudes to the left and the stop body 124 and the A single workpiece P is positioned between the supply bodies 134.

By the repetitive movement of the stop body 124 and the supply body 134, different workpieces P are supplied along the transport conveyor belt 110 at a predetermined interval.

In addition, if a problem occurs in the process of supplying and processing the continuous workpiece P of the deoiling device by the workpiece supplying step S110, the supply of the workpiece P is stopped to damage the additional device and the workpiece P It can prevent the damage.

When the workpiece supply step (S110) is completed, the next step is to fix the workpiece position (S120).

In the step of fixing the workpiece (S120), a position fixing member 140 is installed on one side of the conveyor belt 110 to temporarily move the workpiece P on the upper surface of the conveyor belt 110. This is the step of stopping the workpiece P at the input position by limiting.

Looking closely at the workpiece positioning step (S120), in the state where the workpiece (P) is located on the upper side of the supply body (134), the supply body (134) is moved to the right to move the single workpiece (P) downward To move.

A plurality of position fixing members 140 are installed under the supply body 134. The position fixing body 144 of the position fixing member 140 installed on the lower side of the position fixing member protrudes to the left and the workpiece P is positioned first.

After the workpiece P is positioned on the lower position fixing member 140, the position fixing body 144 of the position fixing member 140 positioned on the upper side protrudes in the left direction to be positioned on the workpiece P.

The workpiece P is precisely positioned at a position gripped by the workpiece input member 200 by the above-described workpiece positioning step (S120).

When the workpiece positioning step (S120) is completed, the workpiece flipping step 130 is performed.

In the step of flipping the workpiece 130, a flip member 150 is installed on the upper side of the transport conveyor belt 110 to grip the workpiece P that is moved in one direction and flip the workpiece P to 180 °. to be.

Looking in detail at the step of flipping the workpiece 130, a plurality of the positioning member 140 in the state where the workpiece (P) is located in the state of the plurality of positioning member 140, the flip member 150 is installed opposite the It works.

The flip member 150 is a lifting cylinder 156 is operated in a state in which the workpiece P is gripped, and the rotating cylinder 154 is operated in a state in which the workpiece P is raised by a predetermined height to operate the workpiece P ) Is rotated 180 degrees as shown in FIG. 6.

When the 180 ° rotation of the workpiece P is completed, the lifting cylinder 156 positions the rotating clamp 152 downward, thereby positioning the workpiece P on the transport conveyor belt 110.

The operation of the flip member 150 as described above is a pre-preparing operation for smoothly discharging the processing oil and foreign substances during the de-oiling process by inverting the processing oil and the foreign material residual space 10 of the workpiece P upside down.

When the workpiece flipping step 130 is completed, a workpiece input step 140 is performed. The workpiece input step 140, the workpiece input member 200 is moved to the conveying conveyor belt 110 side, the workpiece (P) turned over 180 degrees by the flip member 150, the workpiece input member 200 Is a step in which the workpiece input member 200 is moved up, down, left, and right to input the workpiece P into the deoiling drum 304.

Looking closely at the workpiece input step 140, the gripping portion 230 of the workpiece input member 200 moves up, down, left, and right while the opening / closing door 320 of the deoiling member 300 is opened. Then, the processed object P is inserted into the deoiling drum 304 as shown in FIG. 14.

When the input of the workpiece P to the deoiling member 300 is completed by the workpiece input step 140, the workpiece deoiling step 150 is performed.

The deoiling step 150 is a step in which the deoiling drum 304 is rotated at a high speed to remove the processing oil and foreign substances on the work piece P.

Looking at the deoiling step 150 in detail, when the inserting of the work P into the deoiling drum 304 is completed, the door opening / closing cylinder 326 is operated to open and close the door 320 to the deoiling body 302. To close the opening.

When the closing operation of the opening / closing door 320 is completed, the deoiling drum 304 is rotated at a high speed to remove the processing oil and foreign substances of the workpiece using a centrifugal effect.

When the deoiling step 150 of the workpiece is completed, a workpiece discharge step 160 is performed. In the step of discharging the workpiece 160, the opening / closing door 320 is operated to open the upper end of the de-oiling body 302, and the workpiece-input member 200 moves toward the de-oiling member 300 to de-oil. This is a step of discharging the finished workpiece to the outside of the de-distributing body (302).

When the discharging step 160 of the workpiece is completed, the discharging position switching step 170 is provided. The discharge position switching step 170, as shown in FIG. 13, after the workpiece input member 200 is moved to the deoiling member 300 to discharge the workpiece P, the workpiece is transferred to the conveyor belt 110. This is a step of changing the discharge position of the workpiece P of the transport conveyor belt 110 by rotating the rotation plate 232 of the gripping part 230 by 180 degrees from the left to the right before seating (P).

That is, the workpiece input member 200 stops the workpiece P having the de-oiling process completed at a predetermined height of the transport conveyor belt 110.

Then, the rotating conveyor plate 232 of the workpiece input member 200 is rotated 180 degrees, as shown in Figure 13, the transfer conveyor in a state where the deoiling process completed workpiece (P) to the right of the lifting body 222 Seated on the upper surface of the belt (110).

When the discharge position switching step 170 is completed, the home position return step 180 is performed. The return to the original position 180, the flip member 150 is installed on one side of the conveyer conveyor belt 110 to grip the discharged workpiece (P) and flips the workpiece (P) 180 degrees so that it is converted to the original position It is a step.

Looking closely at the return to the original position (180), when the deoiling process complete work piece (P) is seated on the upper surface of the conveyer conveyor belt (110), the reversing member (150) installed on one side of the conveyer conveyor belt (110) Is operated to return the original state by rotating the workpiece (P), which has been de-oiled, by 180 °.

When the return to the original state of the workpiece P is completed by the return to the original position 180, the workpiece P is moved along the transport conveyor belt 110 to complete the deoiling process for the workpiece P.
