A micro-weight measuring system using a guide unit for measurement, comprising:
- an indicator which produces a weight setting signal, a small-feed setting signal and a dropping signal;
- a client which produces a first control signal for performing a control by reception of the weight setting signal in such a manner that the fine grains are fed by a first weight corresponding to the weight setting signal, produces a second control signal for performing a control in such a manner that the fine grains are fed by a second weight corresponding to the small-feed setting signal if the small-feed setting signal is received during the discharge of the fine grains by the first weight, and produces a third control signal for performing a control in such a manner that the fine grains are fed by a third weight corresponding to the dropping signal if the dropping signal is received during the discharge of the fine grains by the second weight;
- and
- a device for measurement which comprises a hopper for storing the fine grains;
- a guide unit for measurement which constantly discharges the stored fine grains from the hopper;
- a vibrator which vibrates such that the fine grains discharged through the guide unit for measurement are discharged by the first weight by the first control signal and vibrates such that the fine grains are discharged by the second weight by the second control signal, wherein the vibration is stopped so that the fine grains are discharged by the third weight through the dropping by the third control signal;
- a container which stores the fine grains discharged through the guide unit for measurement by the first, second and third control signals of the vibrator in order to measure the fine grains;
- and a balance which measures the fine grains stored in the container,
- wherein the guide unit for measurement comprises:
- a body part temporarily storing fine grains such as powders, granules, seeds and pills;
- a first adjusting part which has a first handle rod for adjusting an adjustment plate movable in an up-and-down direction from a bottom of the body part to a certain level, the fine grains being constantly fed through a gap created by adjustment of the first handle rod;
- a guide part wherein a first guide fixing member is provided on a wall surface of the body part and a second guide fixing member is provided on a wall surface opposite to the first guide fixing member and wherein a first elastic guide plate is coupled at its one side with the first guide fixing member and a second elastic guide plate is coupled at its one side with the second guide fixing member, therefore, the fine grains which have passed through the first adjusting part are guided and moved to between the other side of the first elastic guide plate and the other side of the second elastic guide plate;
- and
- a second adjusting part wherein a first plate and a second plate are provided and a first fixing frame coupled with the first plate and a second fixing frame coupled with the second plate are provided and wherein the other side of the first elastic guide plate coupled at its one side with the first guide fixing member is fixed to the first fixing frame and the other side of the second elastic guide plate is fixed to the second fixing frame and wherein a second handle rod is provided which adjusts a gap between the first plate and the second plate depending on the adjustment of a gap between the first fixing frame and the second fixing frame, the fine grains passing through the guide part being discharged between the first plate and the second plate.
