In detail, at least one photographing unit 30 is provided and is located on the outer circumferential surface of the cutting member c. That is, the photographing unit 30 is located on a portion facing the outer direction of the cutting member c provided in the form of a tooth. Accordingly, the photographing unit 30 does not come into contact with the object (m) because it does not come into contact with the object (m) and does not come into contact with the surface (which is formed in the tangential direction of the cutting member (c) and is provided with a step). Friction and collision can be minimized. As a more preferred embodiment, the photographing unit 30 is provided as an imaging means such as a camera, but may further include a separate filter unit to easily photograph the object m from the aforementioned cutting debris t. The photographing unit 30 as described above is connected to the comparison unit 40 to be described later and transmits the brightness b1 of the measured object m to the comparison unit 40.

The comparator 40 serves to determine whether or not the object m is properly cut. In detail, the comparator 40 determines the continuous progression or stoppage of the cutting process of the object m based on the brightness b1 of the surface of the object m to be cut by the contact of the cutting member c. do. To this end, the comparator 40 includes a preset reference brightness b0. The reference brightness b0 is the brightness b1 measured by the photographing unit 30 when the object m is properly cut, and serves as a reference for the determination of the comparison unit 40. The comparator 40 compares the reference brightness b0 and the measured brightness m1 of the object m.

When the reference brightness (b0) is less than the brightness (b1) of the object (m), when the object (m) and the cutting member (c) photographed through the photographing unit 30 are spaced apart, the object (m) It means the case where it has been sufficiently processed by this cutting member (c). In detail, when the object (m) is located between the cutting member (c) of the primary processing unit 10 or between the cutting member (c) of the secondary processing unit 20, the imaging unit 30 When the object m is photographed in the upper and lower directions of the object m, or in one direction and the other direction, shading occurs by the cutting member c close to the object m, which is the object m ) Affects the brightness (b1). That is, when the object m is sufficiently cut by the cutting member c, and the separation occurs, the lightness (b1) of the object (m) is measured to be greater than the reference brightness (b0) because the shading becomes relatively light. Accordingly, the comparator 40 stops driving the cutting member c.

On the other hand, when the reference lightness (b0) is greater than the lightness (b1) of the object (m), the object (m) and the cutting member (c) are in constant contact and the cutting process of the object (m) accordingly Means Therefore, since there is no gap between the object m and the cutting member c, the lightness measured b1 is measured to be small. Therefore, the comparator 40 continuously maintains the rotational movement of the cutting member c.

Through the configuration of the photographing unit 30 and the comparator 40 as described above, it is possible to automatically control the cutting and stopping of cutting of the object m, thereby increasing convenience. In addition, when compared to measuring the thickness of the object (m) through a conventional mechanical configuration, it is not surprising that the accuracy of "whether the object (m) is finished cutting" due to wear of the mechanical configuration is significantly reduced. Can be prevented.
