作業は、作業者にとつて大きな負担であり、作業
能率が悪いものであつた。 In order to reduce the size and weight of conventional small automatic plane machines, a single AC commutator motor is used as a power source to drive the material feeding member and rotary plane blade to cut the material. In order to improve the efficiency of cutting work, efforts have been made to improve the output, power factor, and efficiency of AC commutator motors, and to improve the sharpness of plane blades. However, when a single-phase 100V specification AC commutator motor is used as the power source, there is a limit to its output, and there is a problem that it is not possible to cut the maximum cutting width of the material to the maximum cutting depth in one cutting operation. In order to alleviate this problem, small automatic planing machines have been commercialized in which a gear transmission section is provided in the power transmission mechanism between the AC commutator motor and the material feeding member in order to reduce the material feeding speed. However, due to the structure of automatic planing machines, multi-speed gearing was not possible due to work efficiency, weight, and cost considerations, so only two-speed gearing was possible. Even if the material feeding speed is set to a low speed with two speeds, when cutting a material with the maximum cutting width, it will only be possible to cut up to about 60% of the maximum depth of cut, and it will take several cuts until the target thickness is achieved. The work was repeated. This repeated cutting work was a heavy burden on the worker and resulted in poor work efficiency.

To inexpensively realize and provide a small automatic plane machine capable of finishing processing by cutting work.

御回路、速度設定回路を工夫したものである。 This invention focuses on improving the material cutting ability of the rotary planer blade of a small automatic planer and compensating for the output limit of the electric motor by regulating the material feeding speed. By using it as a machine, the cutting capacity is improved by 20 to 30%, and a small output AC commutator motor is installed to drive the material feeding member.
A semiconductor switching element is connected in series to the power circuit of the electric motor for driving the material feeding member, and the speed control circuit and speed setting circuit are devised so that the material feeding speed can be varied steplessly over a wide range by power control.

ものである。 An embodiment of the present invention will be described with reference to the schematic configuration diagram of a small automatic plane machine shown in FIGS. 1 and 2. Figure 1 shows the front view of the automatic plane machine, with base 1
A head 2 is disposed on top, and these members are connected and fixed by a plurality of columns 3. Material feeding table 4
is attached to the column 3 so as to be slidable in the vertical direction, and is supported by the base 1 via a screw shaft 5. The material feeding table 4 is moved in the vertical direction by operating a lifting handle or an electric motor (not shown).

子電動機を備えているものである。 FIG. 2 shows a left side view and an elevation view of the head 2 shown in FIG. A plane barrel 7 with a plane blade 6 tightened thereon is rotatably supported in the head 2 and is incorporated so as to be rotationally driven by an AC commutator motor 9. Further, a material feeding roller 8 is rotatably supported at the front and rear of the planer body 7, and an AC commutator motor 1
It is installed so that it is rotationally driven by 0.
Therefore, it is equipped with two AC commutator motors: an electric motor 9 that rotationally drives a rotary planer blade composed of a planer blade 6 and a planer body 7, and an electric motor 10 that rotationally drives a material feeding roller 8 serving as a material feeding member. It is something.

る。 The dimension between the upper surface of the material feeding table 4 and the planer blade 6 is the material feeding interval, and is the finished cutting dimension when the material is cut by the planer blade 6. When finishing the material to a predetermined thickness, set the feed interval so that the cutting depth is equal to the difference between the material thickness and the finished thickness, turn on the switch, and start the electric motors 9 and 10.
The material is cut by the rotating planer blade 6 while the material is fed by the feed roller 8.

は、有効な手段となるものである。 The work of an automatic plane machine is to perform one cutting operation at a slow material feeding speed, rather than repeating the cutting operation several times while adjusting the feeding interval until the material is finished to the specified dimensions. Machining to the finished dimensions is much more efficient, takes less time, and reduces work effort. This is particularly effective for small automatic planing machines that do not have a mechanism for automatically reciprocating the material.

回路を設けている。 In the present invention, by using one electric motor that conventionally drives the material feed roller 8 and the planer barrel 7 as a power source for driving the planer barrel 7, the material cutting capacity can be increased from 2 to 2.
In order to improve the output by 30% and compensate for the output limit of the electric motor 9 that drives the planer barrel 7, the rotational speed of the electric motor that rotationally drives the material feeding roller 8 is directly controlled, and the material feeding speed is variable steplessly over a wide range. A speed control circuit is provided to allow this.
以下第3図に示す制御回路図を用い、電動機1
0の速度制御について説明する。 Using the control circuit diagram shown in Figure 3 below, the electric motor 1
0 speed control will be explained.

続して接続されている。 A power switch 11 is connected in series to the single-phase power lines L1 and L2 , a motor 9 is directly connected to the load side of the switch 11, and a triac 13 as a semiconductor switching element is connected in series with the motor 10. connected.

し、電圧値の大小により、トリガパルスの位相角
を変え、トライアツク13の導通角を制御する。 The trigger operation of the triac 13 is performed by outputting a trigger pulse from a phase control circuit 15 which receives a power synchronization signal from a power synchronization circuit 14 that detects the period of the power supply voltage applied to both ends of the triac 13. A predetermined material feeding speed set by the operator is converted into a voltage signal V1 by the material feeding speed setting circuit 12, and the phase angle of the trigger pulse is changed depending on the magnitude of the voltage value to control the conduction angle of the triac 13.

角を制御するようにしている。 However, when cutting materials using an automatic plane machine,
The material pressing force of the material feed roller 8 increases or decreases depending on the uneven thickness of the material or the amount of cutting depth, so the material feeding load fluctuates and the material feeding speed deviates significantly from the material feeding speed set by the operator. . In order to eliminate this problem, the rotation speed of the electric motor 10 for material feeding is detected by the speed detector 1.
6, and converts it into a periodic signal according to the rotation speed, and further converts the synchronizing signal into a speed voltage V 2 by an FV conversion circuit 17, and outputs the voltage V 1 from the material feeding speed setting circuit 12 and the speed voltage. Compare circuit 1 with V 2
8 performs a magnitude comparison, and the output signal of the comparison circuit 18 controls the phase angle of the output trigger pulse of the phase control circuit 15.

It is determined that the material feeding speed has decreased, and the conduction angle of the triax 13 is advanced, the power supplied to the electric motor 10 is increased, and the rotational speed is increased. Conversely, if V 1 <V 2 , it is determined that the material feeding load is reduced and the material feeding speed is too fast, and the conduction angle of the triax 13 is delayed, the power supplied to the electric motor 10 is reduced, and the rotation speed is lowered. The speed is controlled so that the material feeding speed matches the speed set by the operator.

V 2 is compared by the comparator circuit 18 and synchronized with the power supply cycle, and the phase angle of the output trigger pulse of the phase control circuit 15 is controlled to increase or decrease the conduction angle of the triax 13, so that the rotation of the motor 10 It is possible to set the feeding speed steplessly over a wide range and stably.
