Description

Packing machines are sold and sold, and liquids, liquid-filled feed tank, weight tank and electro-hydraulic Fifth scales, which control the relay through the cycle of the machine.

The described automaton is distinguished by the fact that it allows pasteurizing it for the release of two different weight doses. To do this, it used two parallel installed between the consumables. tank and weight tank intermediate vessel, equipped with level tubes. At the bottom of these vessels, exhaust fittings with electromagnetic 1C-pans are mounted, which have spring-loaded plungers in the shape of a stepped cup equipped with side plates: openings.

In order to improve the accuracy of discharging a smaller dose from a weighing tank, the latter is equipped at the bottom with two discharge fittings with solenoid valves, one of the fittings having a height-adjustable tip with side openings.

FIG. 1 shows an automaton; in fig. 2 - intermediate vessels with solenoid valves; in fig. 3 - weight tank.

Auto.mat includes a supply tank, two intermediate vessels 2 and 3, a weight vessel, a tank 4, electrophociated scales, o. The supply of liquid to the supply tank / occurs automatically from the tank 6 by means of the pump 7 through the pipe 8. To automatically turn on and turn off the pump 7 when the tank 7 is released and filled with liquid, there is a float 9 mounted in the supply tank and interacting with the microswitches 10,

From the supply tank 1 liquid nocTjnaeT through the pipe L through the valve 12 through passage to the intermediate vessels 2 and 5, equipped with the tube No. 126540

MP ypoiiiKii /. and //; the lower parts of the tubes are located in the vessels, - pa iiioii iu.coTc so that the liquid, up to the lower part of the tubes, is hidden in their holes and rises along them to the height of the liquid level i; X .-- srpuars. The remaining air of the HC from the top of the vessels 2 3 will enable the vessels to be completely filled. Tubes of levels 13 and / - / are installed on vessels 2 3 so that the volumes of the vessels between the lower parts of the tubes and the bottom of the vessels are somewhat less than each of the two doses of dispensed liquid. Therefore, a pre-dosage of the liquid is made there. The final dosage is produced by weighing cistern 4 and electrified weights 5; the latter control the operation of the machine.

At the bottom of each of the two vessels 2 and 5, there is one outlet fitting 15 and 16 fitted with solenoid valves, which are a plunger 18 mounted under the choke 17 and equipped with a spring 19. The plunger 18 is made in the form of a stepped glass, i.e. Its side drain holes 20. After releasing the weight tank 4 from the liquid, the arrow of the balance 5, being at zero, breaks the contacts of the magneto-mercury switch (not shown in Fig.). This opens the solenoid valve 25 of the vessel 2, and the previously metered liquid in this vessel is drained through the raised plunger 18 and the holes 20 in the weight tank 4. Since the dose of liquid in vessel 2 was slightly less than the specified amount, then the water is added to the weight tank given dose through the vessel 2 thin stream.

When the weigh tank 4 is filled with liquid and the balance arrow approaches to the specified weight (dose), the balance arrow opens the contacts of the magnetic-mercury switch. This closes the solenoid valve 25 of the vessel 2 and the filling of the vessel begins with the next dose of liquid.

The weighing tank 4 has in its bottom part two fittings 2} and 22 drains with solenoid valves 23 and 24; the latter are identical to the electromagnetic “panaman.m 25 and 26 vessels 2 -and 3. The fitting 22 has a tip 27, which can be adjusted in height. This tip is the same as -the fitting 21, has side holes 28. The bulk of the dose of fluid is discharged from the weight tank 4 through the main holes, and the end of the dose is discharged through side holes 28 with a slow jet, which ensures a smooth approach to the balance weight (dose).

When a single token is lowered into the machine, the solenoid valve 24 is turned on, the smaller of two doses is drained from the weight tank 4. When the arrow of the scale approaches 5 to the weight of the lower dose, the relay triggers and the solenoid valve 24 closes. At the same time, the solenoid valve 26 opens, - and the HanOvTHemie-weight tank 4 opens again to a higher dose.

When two tokens are lowered into the machine, the solenoid valve 23 is turned on, and the larger of the two doses is drained from the weight tank 4. When the scale arrow 5 approaches zero division, the contact of the magnetic-mercury switch is dimmed, causing the valve 23 to close and open the valve 25

The weight reservoir is again filled with a higher dose fluid.
