    In a method of controlling the operation of filling elements (10) of a bottle filling machine, each of the filling elements includes an electrically actuable valve (19) for controlling the flow of liquid into a bottle placed below the filling element. The commencement of flow of liquid into each bottle after opening of the respective valve (19) is detected by means of a pick-up (46), and the instant for closure of each valve is determined by a computer operation in dependence on a desired quantity of liquid to be filled into the respective bottle. The pick-up (46) may also detect the flow rate. Control may be enhanced by a feedback system comprising a level detector (57) or a weighing machine (not shown). <IMAGE>

    The invention relates to a control system and can be used in filling machines to control the valves of the filling elements. A known method and a device based on it for controlling the valves of the filling elements of the filling machines fl. The method consists in determining the level of the liquid in the tank with the following its correction The device for carrying out this method contains an electric control unit for liquid valves, with the disadvantage of the known method is that it does not provide correction of the dose depending on the temperature and / or specific gravity and / or weight of the filled container, which affects the accuracy of the dosage. A disadvantage of the known device is that the electric control unit regulates the level of the filled fluid only by moving the height of the replacement tire, and this makes it impossible to obtain high dosing accuracy. The purpose of the invention is to improve the accuracy of dosing
    .. The goal is achieved due to the fact that, according to the valve control method of filling elements of filling machines, which involves determining the level of liquid in the tank, after each valve element is opened, the beginning of the outflow of fluid flow is recorded at each filling element, and the moment of closing the valve for liquid is determined during adjustment depending on the amount of liquid, (fed to the filling.
    In this case, the amount of liquid to be filled can be adjusted depending on the temperature and / or the specific gravity of the liquid and / or the weight of the filled container.
    The beginning of the outflow of fluid flow and its value is recorded after the fluid valve at the outlet of each filling element.
    The measurement of the filling level or the weight of the filled container to form averages is recorded during or after the filled container leaves the filling machine.
    A device for controlling the valves of filling elements of filling machines is equipped with a 5-D computing system having for each filling element a data input and output unit and elements
    fill level.
    The device consists of a filling element 5 that is mounted on an annular chamber 1 with a 9, comprising a housing 3, a liquid valve 4 mounted therein, connected by a pusher 5 to an electromagnetic control mechanism b, a filling tube 7, at the lower end of which the centering a head 8 with a gasket, a block of valve 9 of pressure gas, in the casing of which a disk 10 is mounted and a control lever 11, which interacts with the control cam 12, at. This disk 10 has a radial channel 13 with holes 14 and 15 and from a computer system 16 having
    0 of each filling element block 17 input and output data connected to the receiver 18 measured values, which can be made in the form of a photovoltaic block
    5 and the elements of the regulator 19, containing one common setpoint adjuster 20 of a given size and memory 21 connected to the computer system an additional data input and output unit 22 connected to the control unit 23 by means of a level control device 24 for measuring the height of the filling level of bottles photovoltaic
    A block made in the form of a regulator breaker 8, in this case for all regulators there is one common setpoint adjuster, and on each filling element after the liquid valve a measured value receiver is installed to register the beginning of the fluid flow connected to the data input and output unit . In this case, the receiver of measured values can be made in the form of a photoelectric block or a thermal block. The computing system has a data input and output unit that is common to all elements and is connected to a device that controls the height of the filling level or weights for Continuous Weighing. The level control device has a measuring photovoltaic block installed at the height of the monitored filling level. The photovoltaic unit is designed as a light beam interrupter. Figure 1 shows a filling element for dispensing liquids with backpressure; 2 a filling element with a block diagram for controlling the operation of the machine and 30 a device for controlling height
    the light flux containing the sensor 25 and the receiver 26.
    The device works as follows.
    From the setpoint adjuster 20, a predetermined volume of liquid is introduced into the elements of the regulator 19 and stored in the memory 21. The Start-® that bottle on the table 27 is fed to the filling element 2, centered by the head 8 with a sealing gasket and the filling tube 7 is inserted into it After this, the bottle is pre-filled with gas, and the disc 10 of the valve 9 is rotated from the rest to the working position by the action of the control lever 11, which interacts with the cam 12, and the opening 15 of the channel 13 is in this position communicates with channel 28 for supplying gas, and opening 14 with channel 29 for discharging gas, while gas from channel 28 enters channel 29 and through chamber 30 enters the bottle. Due to the tangential gas injection into the chamber 30, the remaining liquid remains are removed from the chamber walls and from the filling tube 7, which enter through the discharge duct 31, the jet 32, the duct 33 and the air inlet 34. In this position, open to the atmosphere by gas release, the lever 11 is opposite the switch 35 and acts on it so that
    the contact of the switch 36 and the circuit of the electromagnetic control mechanism 6 are closed, while the liquid valve 4 is in the closed position.
    When moving around the circumference of the filling element 2, the lever 11 under the action of the cam 12 rotates the disk 10 back to the rest position, as a result of which the gas supply stops. In this case, the contact of the switch 36 is opened so that the circuit of the electromagnetic control mechanism 6 is interrupted and removes the excitation of the magnets. The fluid valve 4 is lifted up by the action of the spring 37, and the fluid through the chamber 38 and the filling tube 7 enters the bottle. Through the channel 31, the jet 32 and the channel 33, the gas is expelled by the incoming liquid into the annular channel 13 of the air outlet and from there through the opening 39 to the atmosphere. During the outflow of fluid through the valve 4, it overlaps the receiver 18 of measured values, which senses and registers the beginning of the flow. The measured value indicating the beginning of the flow of fluid through the data input and output unit 17 enters the computer system 16,
    which starts the regulating process to determine when the liquid valve 4 is closing.
    The actual value required for the adjustment process, which depends on the flow rate of the liquid, is continuously perceived and recorded by the receiver 18 of measured values from the beginning of the flow and is processed
    0 through input and output unit 17 to the computing system 16. It calculates the instant of time that valve 4 is closed, and at this instant, through input and output unit 17, it sends a signal to the magnets of the control mechanism of the 6-valve 4, as a result of which the magnet is energized and valve 4 g moves to the closed position. With a signal, the adjustment process ends. Upon further movement of the filling element 2, the lever 11 interacts with the next control cam 12, the disk 10 rotates to the leveling position, in which the opening 14 of the channel 13 communicates with the output of the channel 29 of the gas sub-gap, and the opening 15 - with the output of the channel 40. As a result height leveling occurs
    0 levels of fluid inside tube 7 and in the bottle.
    At the same time, the excess pressure, still present in the gas space of the bottle, through channels 40 and 29
    5 is vented through the exhaust duct 31, the jet 32, the duct 33 and the air exhaust duct 34. After the reduction in pressure has been reached, the locking signal is suppressed by means of a data input and output unit 17, as a result of which the excitation of the magnet of the control mechanism 6 stops and the liquid valve 4 is kept in the closed position. Upon further movement of the filling element 2, the filled bottle is removed from the device.
    With or after the release of the filled bottle, its contents are monitored with a level control device 24. The device operates primarily with gamma radiation, which is from a measuring radiation source made in the form
    5 of the sensor 25 with a low dose of radiation, is directed to the receiver 26, which receives weak radiation, since, in addition to the bottle walls, it must pass through its contents, and converts the incoming radiation into electrical impulses in accordance with the degree of sorption. The latter, for each bottle filled with the same filling element, is separately supplied to the GR number 16 through a data input and output unit 17.
    From several separate measurements for each filling element, an average value is formed which is taken into account as correction values in the adjustment process for the corresponding flooded element 2, as a result of which inaccuracies in filling the bottles with liquid are excluded. If the filling changes (for example, the temperature or specific gravity of the liquid, and if these changes are not taken into account in the acting average values as corrective values, then C1 $ the same values or correction values should be corrected accordingly by this change, for example, by changing the setting of the degree of absorption . If there is no need to correct the adjustment process due to the presence of mixing quantities that do not affect the accuracy of the filled amount of liquid, the control of the height of the filling level of bottles using the -f tool 24 to control the level of measurement can disappear and the filling process can be performed as described previously without control 24.
    Receiver 18. The measured values serve only to register. The beginning of the flow of the current and the actual value is formed from many average values, which
    the queue is composed of several, for example, three measured values on bottles filled with the same filling element 2, of-. Measured and recorded at O by method 24 to control the level in computer system 16 as the total real value. In this case, the filling process proceeds as described,
    5 only with the difference that the values measured by the device must be used for the corresponding adjustment to form the actual value.
    24 to control the level before the first total valid value is obtained. The actual average value should be adjusted accordingly with changes in temperature and specific gravity of the fluid.
    The use of the proposed device will allow to obtain an economic effect by increasing the accuracy of dosing.
