The device has measuring channels, each of which contains a sensor 1, a trigger .2, the first element And 3, the second element And 4, the first delay element 5, the second delay element 6, the imaging unit 7 pulses, the element SXHRET 8 and the counter 9. In the device it is possible control the sequence of the passage of products on processing operations. 1 il.

Description

A alarm

The invention relates to a computing and information technology and can be used as peripheral sensors of an automated process control system of discrete production.

The purpose of the picture is to increase the accuracy of the account,

The drawing shows a block diagram of the device.

The device contains measuring channels, made on the sensors t, -1 | product availability, triggers 2 {-2 ", | first elements I, second elements I, first delay elements, second elements 6, -6" delays, drivers 7, - 7 (, pulses and elements of B (-8, prohibition, as well as counter 9.

The device works as follows.

When the product appears at its first processing position, the first sensor 1 generates a signal that cocks the first of the triggers 2 (-2, which are preset to the initial state. If after the transition to the second processing position of the product from the second code) Sensor 1 appears on the registration of the product, it passes the output of the first element I 3j, and triggering the trigger trigger 2. 5 and through the second element 6, the delay resets the trigger 2, to the initial state. or subsequent) of the sensors 1, -1 not ow impulse about the presence of the product, the signal from the trigger trigger delayed by the first element 5, the delay time equal to the processing time and moving the product from position to position, and formed by the array 7, so that it is reliably blocked by the signal from the subsequent sensor 1 - 1 ,, arrives at the first output of the first measuring channel of the city of Zlamenta 8, the prohibition.

If a signal about the presence of a product comes from the output of sensor 1, provided that the previous sensor 1 did not receive a signal about the presence of a product, then a signal is generated that the process is disturbed on the second output of the first measuring channel from the second element AND.

if the signals about the presence of the product come from all sensors, then the input of the counter 9 receives a counting signal about the registration of products.

Claims (1)

The device allows to control and take into account the product not only by the fact of the product appearance, but also by moving the product through all positions of its processing. Invention Formula A device for counting piece goods transported along a conveyor, containing a counter, in each measuring channel an item presence sensor and elements AND, characterized in that, in order to increase the accuracy of counting, a trigger, a pulse shaper, delay elements and a prohibition element are inserted into each measuring channel , the output of the sensor of the presence of the product of the first measuring channel is connected to the first input of the trigger of its measuring channel, the first input of the trigger of each measuring channel, starting from the second is connected to the output of the first element I of the previous measuring channel, in each measuring channel the direct output of the trigger is connected to the first input of the first element I and through the serially connected pulse generator and the first delay element to the first input of the prohibition element whose output is fc the first output of the measuring channel The first element And through the second delay element is connected to the second trigger input, the inverse output - which is connected to the first input of the second element And, the output of which is the second output The output channel of the sensor for the presence of the product of each measuring channel, except the first and last, is connected to the second inputs of the elements AND and the prohibition element of the previous measuring channel, the output of the first element And the last measuring channel is connected to the counter; to the second inputs of the first element And and the element of the prohibition of its measuring channel.
