Abstract

PURPOSE:To make possible the detection of the faulty rotations of a magnetic rotor by allowing a detection coil to come in contact with a magnetic rotation- type mixer and ensuring the detection of the movement state of the magnetic rotor of the mixer using an amplifier and a rotary speed detector. CONSTITUTION:A rotor 12 having a built-in permanent magnet is placed in a mixing chamber 10 of a mixer of more than two different liquids. Then a detection coil 1 is allowed to come in contact with the external wall surface P of the mixing chamber of the mixer with magnetic rotation mechanisms 14 to 16 which rotate the rotor 12, at the bottom of an area outside the mixing chamber 10. After this, an electromotive voltage generated by a magnetic induction effect due to the rotation of the rotor 12 is detected with an amplifier 4 and a rotary speed detector 6. Thus the rotating state of the rotor 12 can be detected. Consequently, failure to attach the magnetic rotor, incorrect attachment of the rotor and all other faulty rotations of the rotor due to the failure of a rotary magnet drive mechanism can be detected and an alarm is sounded to prevent the generation of rejects in advance and also minimize the frequency of such reject generations.

Conventional methods to avoid these situations include using a device that monitors the power supply voltage or current status supplied to the magnetic rotating mixer, or installing a magnetic sensor etc. near the rotating magnet. There are methods of detecting rotation by using a magnetic rotor, but since these methods do not directly detect the movement of the magnetic rotor itself, they are not an effective measure against forgetting to attach the magnetic rotor.
