(54) DEVICE FOR ACCOUNTING AND CONTROL

ITEMS MOVED BY CONVEYOR

The invention relates to automation means that can be used in the creation of automated accounting systems, control and management produced by 1 and processes in various industries, to account for and control items transferred by the conveyor. A device is known for counting articles mixed by a conveyor consisting of photo sensors, installed at the input and output of a controlled section of a reversible counter connected to these photosensors, and an indication of the load of the controlled section connected to a reversible counter. This device allows you to determine the number of lost products after the termination of the supply of the new pairs of goods and the controlled area and care beyond the last product of the previous batch. The closest to the technical drying of the nose is a device for metering and moving along a conveyor, containing an input sensor, an output sensor connected to the subtractive input of the reversible counter, the output of which is connected to the display unit, and the control unit 23. This device is not accurate and reliable. The chain of the invention is to improve the accuracy and reliability of the device. This is achieved by the fact that position sensors are inserted into the device, the first of which is installed on the conveyor, the element I, 1 switch and the counter; The input sensor is connected to the left of the counter inputs and to one of the inputs of the And element, the other input of which is connected to the output of the control unit, which is connected to the output of the control unit, which is connected to the other inputs of the counter, to one of the key inputs and to the control input reversible counter, the summing input of which is connected to the output of the element And, the second and third position sensors.

connected to the inputs of the control unit to the output of the counter connected to another key in the output of which is connected to the information input of the reversible counter.

The drawing is represented. structural electrical circuit of the proposed device.

The first position sensor 3 is fixed on the transport line 1, pj of which the processed padeps are moved. This sensor passes the beginning and end of the LRRT and is fixed by the second and third position sensors 4 and 5, the outputs of which are connected to the inputs of the control unit 6.

Products entering the conveyor are fixed at the beginning of the transport line by an input sensor 7 connected to the input of the additional counter 10, and also through element 8 of the summing input of the reversing counter 9. The products leaving the conveyor are fixed at the end of the transport line. output sensor 11 connected to the subtracting input of the reversible counter 9.

The device also includes a display unit 12 connected to the reversing counter 9, and a key 13, with which the information from the counter 10 is rewritten into the reversible counter 9.

The corresponding outputs of the control unit 6 are connected to the coincidence circuit 8, the reversible counter 9, the counter 10 and the key 13.

The device works as follows. In the initial state at ot-. In the presence of article 2 in the monitored area 1 and at the position of the first sensor 3, as shown in the drawing, counters 9 and 10 are set to zero, and resolving potential from control unit 6 is applied to element 8.

When products 2 arrive at the conveyor 1, sensor 7 generates pulses that push into the input of the additional counter 10 through the element 8 at the summing input of the reversible counter 9.

When the transport line is moved, the first sensor of field 3 of a hornet 3 passes, first past the second sensor of the position of the mark 4, which at this moment generates a command signal for counting a new group of products according to which the unit

Control 6 issues a ban on the passage of pulses from the input sensor 7 through the element 8 and zeroed down on the optional counter 10.

From this point on, the products of the new group, which continue to arrive on the conveyor, are counted only by the counter 10, and in the reverse counter 9 the information on the number of products that arrived earlier is memorized.

After some time, the products 2 begin to leave the limits of the monitored section 1.JHx the quantity is fixed by the output sensor 11, the pulses from which are fed to the subtracting input of the reversible counter 9,

The subtraction lasts until the first position sensor 3 passes by the second position sensor 5, according to the signal from which the control unit 6 generates the following commands:

1) rewrites the contents of the reversible counter 9 in the display unit 12}

2) reset the reversible counter 9;

3) rewrites the contents of the additional counter 10 through the key 13 in the reversible counter 9,

4) delivers the resolving potential on the element And 8,

those. the difference between the numbers of the items 2 coming out of the monitored area 1, 2 calculated by the time the first position sensor 3 passes the position sensor 5, is stored and displayed by the display unit 12, and the number of newly received products recorded in the additional counter 10 is rewritten into the reversible counter 9, which, from this moment, begins to calculate the difference between the number of items entered and left for the new group on the conveyor.

If at least one product is lost in the reversible counter 9 by the time the first and the third position passes by the position sensor 5, a difference is calculated that is distinct from O. This difference is stored in i and displayed by the display unit 12,

Further, the cycle of operation of the device is repeated.

With the help of the label of the first sensor of position 3, we were able to compare the number of products 1 that entered the monitored area 1 to those that left it for each revolution of the conveyor.

Installing the counter 10 allowed to accumulate information on the number of ideals from the new group entering the conveyor, while the reversing one, the counter 9 continues to compare the number of entered and exited products in the previous group.

Increased responsiveness to control

Claims (1)

the passage of products through the process section is achieved by eliminating the time required for the last product from the previous batch to leave the controlled area, i.e. now there is no need for artificial rupture of the flow of processed products.
