This invention relates to weighing and dosing technology and can be used in the chemical, metallurgical and other industries. The invention allows the dosing of four components of the mixture in three grades for each component. The required weight values of the components of the mixture for a given brand are preset on the typing field. The dosing materials from the supply tanks enter the weighing container, the weight meter of which sequentially issues commands to control the drives of the supply tanks 18 to start and stop the supply of the dosing material in accordance with the weight of each material in a mixture of this brand. 1 il.

Description

The invention relates to weighing and dosing technology,

The aim of the invention is to enhance the functionality by providing the dosage of the four components of the mixture in three grades for each component.

The dispenser works as follows.

Before starting the dosing, the required sequence of reed sensors 1, –C, 2, –2, 3, –3,, 4, –4 for the first, second, third, and fourth components, depending on the installed on each brand of recipe mix. So, for example, according to the prescribed recipe for a mixture of four components, sensors 1 ,, 2, 3, and A can be selected for the first brand.

To implement this choice of sensors for the first brand, it is necessary to connect the first longitudinal tire on the dial field 7 with the corresponding transverse tires of said sensors. Similarly, the sensors for the second and third brands of the mixture can be selected according to the required formulation. In this case, when on one of the different brands of the mixture one of the components does not change its size, the corresponding sensor can be selected on several brands at the same time, for which each of the longitudinal tires of the composing field corresponding to these brands is connected to the transverse tire of the specified sensor.

The choice of mark is made with the help of a switch of 8 marks. Thus, preliminary on the dial: field 7. the selection of the corresponding recipe sensors I / -, 2, - -2, 3 {- 3 is carried out. They are also set on the scale of the weight dial indicator 20. The use of dial pad 7 allows each of the three brands to install any given recipe, and the switch 8 brands - choose any desired brand.

After installing the reed 1, -C 3, -3з, A, -AE sensors and dial-up floor 7, the required poppy is selected according to the specified recipe using the switch 8 of the mixture marks, and the dispenser is started up using the start button 12. When you press this button logical 1 from the second power supply unit 10 is fed to the input of a logical element OR, 14 A logical J also appears at the output of this element, arriving at one of the inputs of the logical element

ment I 15-, the second input of which also supplies logical 1 from the output of the inverter 16, to the input of which logical O from the output of the logic element -15 is fed. In the initial state, the output of the logical element 15 is a logical O. Thus, two units are collected at the inputs of the logical element 15a, and as a result a logical one appears at the output

inverting on inverter 1o gives a logical unit. As a result, a logical unit appears at the 5th output of the element 15, which, by means of the first executive amplifier 17, the drive, opens the shutter of the supply tank 18, the first component. When the material is postponed into the weight container 19, the arrow 5 with the magnet 6 begins to move along the weight dial indicator 20. When the magnet 6 reaches the reed sensor of the first component (for example, 1), relay 11 is activated and its contact 13 is closed. In this case, a logical 1 is fed to the input of the OR 14 element (and then appears at the output of the latter. As a result, two logical 1 are collected at the inputs of the AND 15 element and a logical 1 appears at the output of the AND 15 element, which introduces elements 14 and 15, in self-pickup mode and, inverted on inverter 16,, resets the logical unit from AND 155. As a result, the shutter of capacitance 18, is closed and the dosing of the first component is stopped. At the same time, logical 1 from the output of AND 15 is fed to the inputs of AND 152 and 15b. As a result, the ale output The supply And 15g appears logical 1, the shutter of the supply tank 18 of the second component opens. The supply of the second component continues until the arrow with the magnet reaches the selected 5

 : oro on this mark of the reed sensor of the second component (for example, 2). Then the relay JL is activated, the contact is closed. The occurrence of a logical 1 at the output of the OR 142 element results in the appearance of a logical 1 at the output of the OR .14 and accordingly at the output element And 15, which leads to self-grip elements Hj and IS and the closure of the container capacity IS. At the same time, the closure of the container 18j ,, opens, which closes when the arrow with the magnet reaches the corresponding reed sensor (for example, 3) and so on.

Similarly, the control circuit of the fourth component operates (shutter of the supply tank 18). When this circuit is triggered, the appearance of a logical unit on the element And 15 leads to its appearance at the input of the inverter 16J, and accordingly a logical zero at the output of the inverter 16 and at the input of the element 15 ,. Then at the output of the latter also a logical O appears, which successively passes through the logic elements 15, -15, resetting them to the initial state when the logical O appears at their output. The appearance of a logical O at the output of the element 15 leads to unit on inverter 16,., which prepares the circuit for operation in the next cycle.
