Claims (1)

[Scope of utility model registration request] 1. A take-out device for taking out a sample part from a probe having a sample case composed of a sample case and a sprue case for collecting a sample of molten metal near the tip closed part, in a vertical direction and at the tip closed part. The probe cutting device that cuts the lower and upper positions of the sample case of the probe held so that it is on the lower side, and the cut probe is rotated 90 degrees to a horizontal position and the sample is passed from inside the probe through the cut surface of the probe. A sample case ejecting device that pushes out the case and transfers it horizontally, and by inserting the sample case into the fixed blade body and the movable blade body and horizontally moving the movable blade body corresponding to the sample case, A sprue cutting device for shearing and separating the sample case from the case, and a horizontal direction from the movable blade body. A sample rotation separation device that holds the ejected sample part case and rotates it by 90 degrees and drops the sample part from inside the sample part case through the shear surface of the sample part case. A sample turning device with the shear surface facing upward, a sample moving device that grips the sample part and moves it in the horizontal direction, and rotates the sample part 90 degrees after moving, and a sample moving device that can move up and down above the moving path of the sample moving device. The deburring device for deburring the sheared surface of the sample portion by the rotary polishing brush arranged in the above position, and the deburring device for horizontally moving the sample portion in a horizontal position from the sample moving device are arranged so as to be able to move up and down. And a marking device for marking on the side surface of the sample part.
