TitleHigh-speed inspection machine - Failed paper rejection system - (Actual speed)
Frame rate25fps
Resolution640x480
Results

Actual speed movie using camcorder.

TitleHigh-speed inspection machine -Failed paper rejection system-
Frame rate250fps
Shutter speed1/2000
Resolution640x480
Obtained waveforms

CH1: Result of inspection judgement - passed
CH2: Result of inspection judgement - failed

Results

NG rejection bar rises when CH2 signal dropping down and downs when CH1 signal dropping down synchronously.

TitleHigh-speed inspection machine -deliver and sort system- (actual speed)
Frame rate25fps
Resolution640x480
Results

Actual speed movie using camcorder.

TitleHigh-speed inspection machine -deliver and sort system- (After adjustment timing)
Frame rate250fps
Shutter speedOpen
Resolution640x480
Obtained waveforms

CH1: Driving motor voltage of a sorting system (モータ駆動電圧)
CH2: Optical sensor on the conveyor exit (出口センサー)

Results

Waveform of CH2 seems stable, it means feeder of inspection machine can feed well. Also delivery machine form finely.
After adjustment timing, the sorting system can sort set value.

TitleHigh-speed inspection machine -deliver and sort system- (Before adjust timing)
Frame rate250fps
Shutter speedOpen
Resolution640x480
Obtained waveforms

CH1: Driving motor voltage of a sorting system (モータ駆動電圧)
CH2: Optical sensor on the conveyor exit (出口センサー)

Results

A waveform of CH2 is unstable. This means feeder of inspection machine does not feed uniformly. Also delivery machine cannot form well.
Sorting system work slower than designed, therefore system cannot sort number of setting.

TitleCard feeding failure
Frame rate250 fps
Shutter speedOpen
Resolution640 × 480 (pixels)
Obtained waveforms

CH1: Sound data from the sound collector (microphone)
CH2: Speed data from the acceleration sensor

Results

The behavior of the machine, including sounds and vibrations, can be confirmed in the event of card feeding failure.

TitleGear behavior
Frame rate500 fps
Shutter speedOpen
Resolution512 × 292 (pixels)
Obtained waveforms

CH1: Sound data from the sound collector (microphone)

Results

Specification of noise generation points during gear rotation

TitlePunching robot
Frame rate250 fps
Shutter speed1/2,000
Resolution640 × 480 (pixels)
Obtained waveforms

CH2: Control signal from the remote controller block to the motor.

Results

Demonstration of triggering of recording by the control signal. Robot behavior when the control signal is switched can be confirmed.

TitleDrill
Frame rate1,000 fps
Shutter speed1/2,000
Resolution384 × 188 (pixels)
Obtained waveforms

CH1: Sound data from the sound collector (microphone)

Results

Correlation between the movement of the blade or the cutting powder and sound generated during cutting can be confirmed.

TitleMilling cutter
Frame rate1,000 fps
Shutter speed1/5,000
Resolution384 × 188 (pixels)
Obtained waveforms

CH1: Sound data from the sound collector (microphone)

Results

Correlation between the movement of the blade or the cutting powder and sound generated during cutting can be confirmed.

TitleLathe
Frame rate1,000 fps
Shutter speed1/5,000
Resolution384 × 188 (pixels)
Obtained waveforms

CH1: Sound data from the sound collector (microphone)

Results

Correlation between the movement of the blade or the cutting powder and sound generated during cutting can be confirmed.
