S1) (the first space S1).

Here, the first position detecting sensor 100 is a sensor that can confirm whether or not the material M is inserted into the receiving groove H1, and it can be any one of mechanical, electric, magnetic, and optical position sensors . Also, the second position sensing sensor 200 and the third position sensing sensor 300, which will be described below, may be the same position sensor as the first position sensing sensor 100.

When the controller 500 determines that the workpiece M is positioned in the grip space S1 as a result of the detection by the third position sensor 300, the controller 500 controls the contact portion 52 to contact the workpiece M 52).

The control unit 500 controls the position of the contact unit 52 based on a result sensed by the second position sensor 200 before the contact unit 52 is controlled so that the contact unit 52 and the workpiece M are in contact with each other. The contact portion 54 is controlled so that the contact portion 52 is moved from the second position to the first position.

The material M accommodated in the accommodating portion 42 is first moved through the material moving portion 44 and the moved material (M) is gripped by the grip portion (50) and moved to be seated on the fixing portion (10).

Specifically, the control unit 500 causes the first rotary unit 62 and the second rotary unit 64 to sequentially rotate while the workpiece M is being machined by the processing unit 30, Is positioned on the lower side of the fixing part (10).

If the contact between the processing portion 30 and the workpiece M is not maintained for a predetermined time as a result of the detection by the first vibration sensing portion 400, M is completed and the radial moving part 14 is returned from the fourth position to the third position so that the material M that has been brought into contact with the radial moving part 14 is dropped to the material collecting part 60 .

When the material M processed by the machining unit 30 is returned to the material collecting unit 60, the control unit 500 determines whether the resultant receiving groove H1 sensed by the first position detecting sensor 100, It is determined that the material M is not inserted into the gripping space S1 and the material M accommodated in the accommodating portion 42 is moved to the gripping space S1.

In other words, the series of processes described above are repeatedly performed so that the plurality of workpieces M accommodated in the accommodating portion 42 are processed by the processing portion 30, respectively.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent to those skilled in the art that changes or modifications may fall within the scope of the appended claims.
