FIG. The invention relates to the building materials industry, in particular glass technology and glass manufacturing. The purpose of the invention is to increase reliability and increase the yield of products. FIG. 1 shows the device, the general scheme; in fig. 2 - section A-A, in FIG. one; in fig. 3 - pneumatic pulsator circuit. The device includes channel 1, point 2, element 3, cylinder 4 with protrusions 5 located at the level of slots 6 with an area slightly larger than the area of the slots, cylinder actuator 7, control device 8, pulveriser 9 consisting of salt track 10, bellows 11, the hard center of which is connected to the plunger of the solenoid 10 and with the spring 12, at the end of which a valve 13 is placed a glass 14, divided by a partition 15 into two cavities, one of which (upper) is connected to the atmosphere 16 and the other (lower) - with bellows cavity and with pneumatic outlet 17 indented to the hollow element 3. The device operates as follows .. When the cylinder 4 rotates, the slots 6 in the hollow element 3 periodically overlap the projections 5. At the moment when the slots 6 overlap with the hollows 5, from the control device 6 mechanically connected with the drive 7 cylinder, supplied by electric,. Combined pulse of pneumatic pulse 9 input (solenoid 10). As a result, the bellows 11 is compressed and the valve 1 closes the cup 14 (the connection between the cavity plug and the atmosphere 16 is closed). With further compression of the sylphs to the valve 13, it remains closed (spring 12 is compressed) and the pressure in the cavity of the background forces increases. Through the bottom of the glass 14-septum 15p, the pneumatic output 17 of the pressure pulse from the bellows cavity is transferred to the hollow element 3 and under its action the glass mass is pushed through point 2 to form a drop of glass. The gap between the slot and the protrusion is chosen so that the resistance to the flow of the glass mass through the gap is many times greater than the resistance to the flow through the point (the gap is approximately 2-3 mm). A drop of glass is cut off by a scissors 5I and fed to forms (not shown). Upon further rotation of the cylinder, the pilot switches off the pneumatic pulsator solenoid, the bellows and the associated valve returns to its original position, the hollow element 3 through the pneumatic outlet 17, the bellows cavity 11 and the upper part of the cup 14 is in communication with the atmosphere. The glass mass through the free slots 6 enters the inside of the hollow element 3. After the slits overlap, the cycle of feeding the glass mass to the forms repeats. The adjustment of the feed rate is made by changing the cylinder speed. In order to get the most homogeneous glass melt inside the hollow element, the slots 6 are located at a distance equal to 1/2 to 3/4 of the glass melt flow depth, i.e. in the zone of greatest flow rates. At a distance greater than 3/4 of the depth of the stream is captured in the slot of the glass melt with a lower temperature. The proposed device, in comparison with the known, is characterized by a higher quality glass at the outlet of the feeder, since the glass mass is supplied from the flow layers with higher homogeneity as well as higher reliability, since there are no moving parts to push portions through the glass through in the known devices there is a reciprocating} the first setting of the plunger or hollow element and the rotation of the cylinder (bush nga) for averaging the glass mass). In addition, due to the presence of protrusions on the cylinder at the level of the slots of the hollow element, more intensive mixing of the glass mass is performed before it enters the formation of a drop, which also improves the homogeneity of the glass mass.
