Description

(54) CONTROL AND MEASURING DEVICE TO SORTING AUTOLITES AC alternator 1 that feeds two eddy current probes 2 and 3, of which (operating) 2 contain contr. product 4, on which the loading unit 5 is incident, and the other (offset) 3 contains the reference (compensating) product 6 differential element 7, the normal elements 8 and 9, which control the electromagnetic interlocks 10 and 11 of the sorting device 12, and the program block 13, controlling the operation of the keys 14-18 and the loading unit 5. The monitoring device is also equipped with units 19 and 20 for the first and second measurements, respectively, and a comparison unit 21. Moreover, erasing of the used information stored in memory blocks 19, 20, is performed, for example, at the beginning of each measurement cycle, at the command of the program unit 13. The monitoring device operates as follows. I Alternator excitation-. gives converters 2 and 3. Differential element 7 from the EMF of the measuring windings of converters 2 and 3 forms a DC voltage, the magnitude of which is proportional. on the difference of these emfs. In the initial state, all the keys 14-18, controlled from the program unit 13, are in the unlocked state. The entire measurement cycle consists of two cycles. At the beginning of the first clock cycle, for example, the time of the feed to the control of the next monitored item 4, the reset inputs of the blocks 19,20 from the program block 13 are given a signal that sets the memory blocks 19,20 to the initial state (reset, t. e. erasing, stored information). Then load the node 5 by the command of the program block 13 creates in the product 4 a predetermined initial elastic de-. a formation that, in particular, may be zero. This deformation closes the key 14 and the output of the differential element 7 is connected to the input / record dock of memory unit 19: the first measurement result is stored (recorded). Then k; 14 opens. In the second stroke, in the product 4, the elastic node is created by the loading unit 5. deformation. different from the initial. After the installation of the foam in item 4 of this deformity. The Research Institute closes the key 15 and now the output voltage di4 "| Element 7 is fed to 6JJOK of memory 20 — nodal of 1; VYG I -.lil: nOi HSllO (;; L; G :.
