The invention relates to the glass industry.

The purpose of the invention is to improve the accuracy of the controller.

Figure 1 shows the block diagram of the controller; Fig. 2 is a graph of the operation of the elements of the glass mass level regulator;

The regulator of the glass melt level contains an electrode 1 located above the glass melt 2, a level sensor 3, an inertor 4, a loader drive control unit 5, the first 7, the second 8 and the third 9 time relays, the OR element 10 and the AND 11 element.

The regulator works as follows.

In the absence of contact by the electrode 1 of the glass melt 2, a high potential is supplied from the level 3 sensor, while 1 is present at the input and output of the OR 10 element, time relay 8, time relay 7, And 11 element, and input 9 of the relay through time inverter O. From the output of the element 11 to the control block 5 is fed 1 - the drive 6 of the loader is turned on. When the glass touches the electrode, O appears at the input and output of element 10, and therefore, at the second input of element 11 and at its output, the loader is turned off. After a predetermined time delay T2 (fmg.2), a high potential from the output of relay 8 disappears and appears at the output of turn-off time 9 and then at the outputs of the element OR 10, the input and output of time relay 8 and the element 11, the loader starts up. After time Ti, the time delay set on relay 9 ends, and O is input at its output, and therefore O is present at the output of the OR 10 and AND 11 elements — the loader disconnects. After a while Ta ends the time delay on the relay 8 and O appears at its output, which leads to the operation of the relay 9 of time and the presence of 1 at its output and then on the elements OR 10 and I 11 - the loader turns on and the cycle repeats . Such a cyclic supply of the charge to the furnace is carried out until either the time delay T3 expires. Installed on the relay 7, and at its output O, the obstacle

switching on the loader from time relays 9 and 8, or the circuit between the electrode and the glass melt and the input of the element OR 10 is turned 1, which will turn on the loader for a time until the glass rotor again touches the electrode.

This device allows ensuring stable distribution of the charge over the glass mass mirror, improving the temperature uniformity of the glass mass and increasing

yield of products.

Formula of the invention The regulator of the level of a glass melt containing the sensor of the level of a glass melt, the first time relay and the control unit of the drive

the loader, which is based on the fact that, in order to increase the accuracy of the regulator, it introduces a second and third time relay, an inverter, and AND and OR elements, with the level sensor connected to the first

the input element OR and through the first time relay to the first input of the element I. the output of the element OR is connected to the input of the third time relay and the second input of the element AND, the output of the second time relay is connected to

the third input of the element I and through the inverter is connected to the input of the third time relay, the output of which is connected to the second input of the element OR, and the output of the element AND is connected to the input of the drive control unit loader.
