UrioOpereHne refers to the automatic addressing of goods on the conveyor, in particular, to consider addressing devices,

The purpose of the invention is to simplify the device by reducing the electromechanical connections of the sensors with the control panel.

The drawing shows a reading pattern for addressing loads on a conveyor.

The reader contains output contacts 1 and 2 pairs of sensitive elements, for example, reed switches, through counter-switched diodes 3 and 4 connected to a resistor 5 with a corresponding nominal value, a trigger device 6, whose input is connected to the synchronous output of the analog-digital converter (ADC) 7 The outputs of which are connected to the corresponding inputs of the decoder 8, the second outputs of the pairs of contacts 1 and 2 are combined and connected through the corresponding variable resistor 9 to the first output of the trigger device 6, and through The contact contact of the resistor 9 is connected to the first input of the ADC 7. The second terminals of the resistors 5 are connected and connected via the corresponding variable resistor 9 to the second input of the ADC 7. The power source 10 is connected to the corresponding input of the device 6.

The trigger device 6 contains a trigger 11 with a counting input connected to the input of the device 6, the outputs of the trigger 11 through the corresponding transistor switches 12 are connected to the outputs of the device 6. The corresponding outputs of the transistor switches 12 are connected to the power supply 10

The device works as follows.

When the address with the control element passes through the interaction zone with the corresponding sensitive element, its contact, for example 2, closes and through the corresponding diode 4 and resistor 5 the current of the power supply 10 from the second output of the device 6 flows to the first, the value of which is proportional to the nominal value resistor 5. The voltage removed from the moving contact of the resistor 9 is converted by the ADC 7 into a code corresponding to the magnitude of the voltage and polarity. Code

is decoded by the decoder 8 and a signal appears at the corresponding output, which unambiguously informs, for example, the location of the addressee.

The next trigger clock from ADC 7 triggers trigger 6, and if one of the contacts 1 is closed, a current flows from the first output of the device 6 to the second through the corresponding resistor 5 and diode 3. A signal appears at the corresponding output of the decoder 8, which takes into account, besides the magnitude and polarity of the voltage, respectively, and informs the location of the addressee in the zone of the corresponding sensing element with the output contact 1.

Thus, the use of resistors 5 of different ratings allows you to determine a pair of sensitive elements that have an addressing device, and counter-switching on diodes 3 and 4 allows you to select from a pair of specific elements that the addressing device has reached in the current direction. Resistor 9 selects the value of the voltage range converted by the ADC 7.
