摘要： PROBLEM TO BE SOLVED: To improve the measuring speed by reducing measuring cycle time and also improve the measuring accuracy. SOLUTION: The weight measuring scale has a first charging means 1 for charging an object 7 to be measured of about 96% weight of measuring value to a first measuring hopper 5 and a first measuring means 2 for measuring the charged weight by the first charging means 1 and operating insufficient weight to the measuring value and also discharging the object to be measured from the first measuring hopper 5 and a second charging means 3 for charging the object to be measured to a second measuring hopper 19 and a second measuring means 4 for discharging insufficient object to be measured from the object to be measured charged to the second measuring hopper 19. The object to be corresponding to the insufficient weight is discharged from the second measuring hopper 19 before starting discharging of the object to be measured from the first measuring hopper 5 and discharging of the object to be measured corresponding to the insufficient weight from the second measuring hopper 19 finishes after the discharging of the object to be measured from the first measuring hopper 5 is started.

摘要： PURPOSE:To prevent the vibration of measuring signal and to improve accuracy by supplying according to the difference between the 2nd set up weight which is bigger than that in case of a measuring signal being less than the 1st set-up weight and by controlling the supply with a specific signal in case of more than 1st set-up weight. CONSTITUTION:The signal that the supply from a supplying unit 2 is measured at a measuring part 4 is compared by a comparative means 6 with the 1st set up weight and in case of less than 1st set-up weight the function signal of the difference from the 2nd set-up weight which is larger than the set-up weight thereof is transmitted to the unit 2 from the 1st controlling signal generating means 8. When the measuring signal is found bigger than the 1st set-up weight the prescribed signal is transmitted from the means 6 to 2nd controlling signal generating means 10 and the means 10 transmits to the unit 2 the signal that has the size less than the function signal at that time and the size is constant. The vibration of a measuring signal can be thus prevented with the continuous controlling of the flow by the signal from the means 8 and the measurement with good accuracy can be performed by the signal from the means 10.

摘要： PURPOSE:To shorten a measuring time and to improve accuracy by transmitting a feeding signal from a comparing part every time passing through numerous set weights set up in advance and by measuring with the control of the feed from a feeding device by the size of a signal. CONSTITUTION:A driving shaft 18 to open and close the lower end of a storage hopper 12 of a feeding device 10 is connected to a servomotor 22 and potentiometer 24 and the outputs of the potentiometer 24 and of D/A convertor are inputted to a servo amplifier 26. The motor 22 is also driven by the amplifier 26 so as to make the potential difference of both inputs zero and the quantity according to the output of the convertor 28 only is thrown into a measuring hopper 30 from a throwing-in gate 14. The measuring signal is then functioned as a comparing part by its being fed to a microcomputer 40 via A/D convertor 38 and also is made to control the opening and closing of the gate 14 and a discharging gate 42 as a controlling part. The vibration of a signal at the time of changing a throwing-in can be thus prevented.

摘要： PURPOSE: To provide a quantitative charging device that is able to charge a measured material being varied in bulk density in a quantitative manner accurately and speedily, and further making wide range and trace amount of weight adjustments achievable. CONSTITUTION: This charging device is provided with a large charging storage tank 1 and four adding storage tanks 4a to 4d of 1:2:4:8 in volume ratio, and measured materials are fully filled up in these storage tanks 1 and 4a to 4d. An extent of volume in the large storage tank 1 should be set to be smaller than the target weight and so as to make the measured materials in weight approximating to this target weight storable. The measured materials in the large charging storage tank 1 are measured as large charging weight by a load cell 7, and weight of the measured materials in these four adding storage tanks 4a to 4d is found out by calculation from bulk specific gravity is sought by large charging weight and volume, then a proper combination of these adding storage tanks 4a to 4d is selected so as to become nearest to insufficient weight. The selected materials in the adding storage tanks are charged into a vessel 10 via a chute 9 together with the measured materials in the large charging storage tank 1. In consequence, since this bulk specific gravity of the measured material is sought, the measured materials being varied in bulk density can be quantitatively filled up accurately and speedily.

摘要： PURPOSE: To provide a fixed quantity filling apparatus with which fine weight adjustment can be done in a wide range. CONSTITUTION: A large input storage tank 1 and four addition storage tanks 4a-4d in a capacity ratio of 1:2:4:8 are installed and these tanks are filled with a material to be measured. The material to be measured in the large input storage tank 1 is measured as a large input weight by a load cell 7 and to make up for the difference (a deficient weight) between an object weight and the large input weight, (n) times (n>=0) of additional input from all of the addition storage tanks 4a-4d and additional input only from selected addition storage tanks are carried out. Together with the material to be measured in the large input storage tank 1, the material to be measured which is inputted by (n) times of the additional input and the additional input from the selected addition storage tanks is inputted to a container 10 through a chute 9. Since the additional input from the additional storage tanks 4a-4b can be carried out repeatedly, weight adjustment in a wide range can be done and fine adjustment in which the capacity of the addition storage tank 4a becomes the minimum weight unit can be carried out.
