Then, the sharpening step of step S12 is executed to sharpen the sharpened portion 31 of the pencil 3 by the pen blade 2 provided in the pencil insertion portion 111.

Next, the control module 14 performs the determining step of step S13 to determine whether the pen knife 2 can complete the sharpening of the pencil 3 to be sharpened portion 31 within a reasonable sharpening time. When the sharpener 2 finishes the sharpening of the to-be-sharpened portion 31 within a reasonable sharpening time, the representative pencil sharpener 2 is still sharp and can continue to perform the sharpening of the pencil 3. In this case, the control module 14 counts the sharpener 2 The number of times of sharpening, and then the sharpened portion 31 to be sharpened by the pencil 3 is withdrawn from the pencil penetrating portion 111, and then the punching step of step S14 is performed to cut the punching module 12 from the pencil 3 to complete the sharpening. The sharpened portion 31 is to be re-executed, and then the first control program is re-executed to cause the pencil sharpener 2 to perform the sharpening procedure for the pencil 3 at the next stage, while sharpening the other sharpened portion 31 of the pencil 3.

In step S13, when the pen knife 2 cannot complete the sharpening of the to-be-sharpened portion 31 within a reasonable sharpening time, the state of the pen-knife 2 is not good and the sharpening cannot be performed. In this case, the control module 14 will Performing the definition step of step S15 in the second control program, stopping the pen knife 2 to perform the sharpening procedure of the next stage, and recording the total number of times the pencil sharpener 2 currently sharpens the pencil 3, and recording the total number of sharpening times It is defined as the number of torsion sharpening of the pen knife 2, and is used as the basis for judging the sharpening ability of the pen knife 2.

Alternatively, the pen knife detecting device 1 of the present invention has a warning module 15 , a length sensor 16 and a refueling module 18 . The length sensor 16 is for the control module 14 to sense whether the length of the pencil 3 provided by the feeding module 13 is sufficient. The refueling module 18 replaces the pencil 3 of insufficient length from the feeding module 13, and causes the feeding module 13 to obtain a pencil of sufficient length from the trough 17. The control module 14 can provide the warning module 15 with external warning when the pencil blade 2 cannot complete the sharpening of the pencil 3 within a reasonable sharpening time, or when the length of the pencil 3 provided by the feeding module 13 is insufficient. . Preferably, the control module 14 can execute the refueling module 18 when the length of the pencil 3 provided by the feeding module 13 is insufficient, so that the control module 14 can smoothly perform the feeding step S11 in the first control program.

In the present invention, the sharpening module 11 has a power source 112 for supplying power, and the power source 112 can drive the pen blade 2 of the sharpening module 11 to sharpen the sharpened portion 31. For the power source 112, the sharpening module 11 can also add a power consumption sensor 113 for sensing the energy consumption of the power source 112, and thus the control module 14 is transmitted through the energy consumption sensor. As a result of the sensing of 113, it is judged whether or not the pen blade 2 can sharpen the sharpened portion 31 to be in a reason of a sharpening time. In detail, during the process of sharpening the sharpened portion 31 of the pencil 3, the power consumption of the power source 112 can not be lowered to a predetermined value within a reasonable sharpening time, which represents the sharpness of the pen knife 2. The lowering of the portion to be sharpened 31 cannot be effectively removed, so that it can be judged that the sharpening of the to-be-sharpened portion 31 cannot be completed within a reasonable sharpening time.

However, in the present invention, the addition of the front energy sensor 113 is not necessary. For example, the sharpening module 11 may further add a resistance sensor 114, and the resistance sensor 114 is a pair of sensing pens. The resistance of the pencil 3 to be sharpened is corrected, and the control module 14 receives the sensing result of the resistance sensor 114. The sharpening resistance cannot be lowered to a predetermined value during a reasonable sharpening time, and also represents a pen. The sharpness of the knife 2 is lowered to effectively cut off the portion to be sharpened 31, so that it can be judged that the sharpening of the to-be-sharpened portion 31 cannot be completed within a reasonable sharpening time.

In summary, the pen-knife detecting device and the detecting method thereof of the present invention perform the sharpening of the to-be-sharpened portion of the pencil by repeated repetition until the pen-knife can not complete the sharpening of the pencil to be sharpened portion within a reasonable sharpening time. The invention can be used for detecting the sharpening ability of the pencil sharpener of various pencil sharpeners on the market, so as to ensure that the life of the pencil sharpener can meet the expectations.
