Node 7 controls the capacity and height of the product contains a lower chamber 39, which is at the base. The bottom wall of the chamber is a membrane 40 on which is fixed; pin rod 4i. Under the action of the spring 42, the membrane 1 and 40 and the rod 41 retrace downward. Coaxially with the lower chamber 39 there is a chamber 43 with a membrane 44, a contact rod 45 and a spring 46. The chambers 39 and 43 are connected to the ejector 47 and the jet sensor 4-8 on the volume of the product. Above the chamber 43 there is a housing 49 with a measuring nozzle 50 of a pneumatic converter of lens dimensions.

The device works as follows.

The controlled products are delivered by the feed mechanism to the channel 2. At the command of AIR, the control unit is located in the sonlo 3 and the product is no longer air-jetted to the control unit 4. In this case, an overpressure will be created in channel 2. Preferred to the arrival of the next day of its products from the boot device. Pr1 1 relieving the pressure from the nozzle 3, the next product is placed on the charging point. A product that has fallen on a knot; trol; 4, covers a hole 36, which irides out, to an increased discharge created by an ejector 37.

By blowing air in the rod end, the poreplate 15 moves up quickly. At the moment of removal of the load, the charge is measured and compared with a predetermined value. Depending on the measurement result, a command is sent to the co-ordinate of the nozzle SI and 12 of the sorting mechanism.

After approx (; the measurement unit is switched off, the ejector 37 is turned off and air is supplied to the nozzle 5. Pzde, these are a jet of air but channel 6 receives capacity control unit 7, and in its place a node ;:;., Г1,; rela. Izd. 2 downloads.

The upper end of the contact rod 45 performs}) the gate of the sensor valve 50 of the measuring converter. Depending on the size of the product being controlled, the .lariop between the torus rod 45 and the nozzle m. 50 varies. This leads to a change in the gauge, first and foremost, for which iio is judged on the size of the product. The measure of measurement is equal to the set and formatting, but on the corresponding-le nozzles 11 and 12 of the sort-a. After the measurements are finished, the ejector 47 is supplied from the ejector and the air is pushed through the transport channel 9. Achievement of the product complies with the required data, the tray 10 of the node by the action of air from the air flowing out of the nozzles 11 and 12, the product is moved to this tray. When moving the product on the tray 10 sensors 13 fix its passage and give a command to start a new cycle.

The proposed device allows monitoring and sorting the piezoelement by three parameters: the piezoelectric module, capacitance and linear size. Known devices are designed to control only one parameter. Consequently, the proposed device replaces three devices at once.
