いう欠点があった。However, in the conventional method, the cutting length was actually measured and the result was reflected in the rotation speed, making continuous control impossible.
In addition, there is a drawback that the optimal rotation speed for obtaining a predetermined cutting length cannot be obtained unless la sampling of the cut object is repeated several times for actual measurement.

回転数を制御する方法を提供することにある。An object of the present invention is to provide a method of automatically measuring the cutting length and controlling the rotation speed of the rotary cutter in order to obtain the optimum rotation speed of the rotary cutter.

とを特徴とする。In order to measure the length of the cut object after cutting, the present invention disposes two photodiodes near the cutter, measures the incident light interruption time when the cut object passes through the detection hole, and measures the length of the cut object. The length is measured, and a comparator circuit determines whether the automatically measured cutting length is plus or minus the predetermined length.
Send it as a current signal to the rotary cutter motor,
It is characterized by controlling the rotation speed and automatically obtaining the maximum rotation speed.
以下、本発明の一実施例を図により説明する。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

程に送られる。That is, the object to be cut 3 is cut by a fixed blade l and a rotary blade 2 rotated by a motor 10, the object to be cut 3 is sent to the fixed blade l by a guide 6, and the object to be cut after cutting is The object 4 slides down the slide 5 and is sent to the next process on the conveyor 7.
本発明は、被切断物４の長さを切断直後に測定するため

被切断物４がその検出孔上な滑下できるような構造とし
ている。In the present invention, in order to measure the length of the workpiece 4 immediately after cutting, a photodiode 8°9 is arranged on the top of the slide 5,
The structure is such that the object to be cut 4 can slide down over the detection hole.

。FIG. 2 shows an enlarged view of the contact portion of the fixed blade l1 and the rotary blade 2. When the object 3 to be cut is cut by the fixed blade 19 and the rotary blade 2 and begins to fall on the slide 5, the detection hole of the photodiode 8 is first blocked to block the incident light. If it falls further, it blocks the detection hole of the second photodiode 9 and causes a detection current of O. Therefore, we measured the time t1 during this time,
The passing speed of the object 4 to be cut is measured. (See FIG. 3) When the object 4 to be cut falls further and passes through the detection hole of the photodiode 8, the light beam enters again, and the photodiode 8 outputs a signal current. Measure the time t2 so far, and
The length of the object to be cut 4 is measured together with the entangled passing speed.

れ、回転刃２の回転数制御に供される。The measured cutting length is compared with a predetermined length in a comparison circuit. After that, the difference signal of the cutting length is sent to the control circuit which sends a signal to the motor 10 to decrease the rotation speed if it is too short, and sends a signal to the motor 10 to increase the rotation speed if it is too long. Served for number control.
ロータリーカッターは、連続運転であるため上述の過程
が繰り返し行われ、常に回転刃の最適回転数制御が可能
となる。Since the rotary cutter operates continuously, the above-mentioned process is repeated, making it possible to always control the optimum rotational speed of the rotary blade.

Since the optimum rotation speed can be easily obtained, the life of the rotary cutter can be extended and its maintenance can be facilitated.
