(54) DEVICE FOR COUNTING THE NUMBER OF DETAILS IN TARE

The invention relates to automation and can be used in industries of heavy industry, in particular in mechanical engineering, where it is necessary to take into account the details associated with the same unknown number of details.

And there is a device for determining the number of items of equal weight, which contains QI (scale, dividing unit, the input of which is connected to the output of the scale memory block of parts, and the output is at the input of the digital scoreboard, keyboard outputs are connected to the inputs of the scale memory block of parts Cl3

This device allows you to determine the number of items of equal weight, but it does not allow for the counting of parts in a container, and to recognize the type of part, so information about the weight of the part is entered at each weighing.

The closest to the proposed technical solution is a device for counting the number of items of equal weight, containing digital scales, a digital scoreboard, an information input unit, a comparison unit, the first output of which is connected to the first input of the first memory block, counters, and OR C2 elements.

The device allows you to determine the number of objects equal to the mass, but does not determine the number of objects in the container, it does not just allow automatic recognition of the type of object, so the weight of the object is inserted into the device each time it is hung.

The purpose of the invention is to expand the scope of application of the device. The goal is achieved by the fact that the device for counting the number of parts in a container containing digital scales, digital display board, information input unit {comparison unit, the first output unit of which is connected to the first input of the first memory unit , a subtraction unit, a dividing unit and a second memory unit are inputted, the input of which is connected to the first output of a digital scale, the second output of which is connected to the first input of the deduction unit, the output of which is connected to the first input of a division unit, output The ports of which are connected to the first input of the pyramid board and to the input of the comparison block ;, the second output of which is connected to the second digital board, the output of the second memory block is connected to the second input of the subtractor, the outputs of the first memory block are connected to the third input of the digital board and with the second input of the division unit, the third input of which is connected to the first output of the information input unit, the second and third outputs of which are connected respectively to the second and third inputs of the first frame unit. In addition, the comparison block contains the AND elements, the OR element, the summation and the registers, the first inputs of which are connected to the input of the comparison block, the first and second outputs of the first register, respectively, through the first and second elements AND, connected to the inputs of the OR element, the output of which is connected to the output of the comparison unit and the second input of the second register, the output of which is connected to the first input of the adder, the second input of which is connected to the output of the first element AND the output of the adder is connected to the second output of the comparison unit. FIG. 1 shows a block diagram of the device; in fig. 2 - functional diagram of the execution unit comparisons. The device contains digital scales 1, subtraction unit 2, dividing unit 3, digital display 4, information input unit 5, first memory unit 6, comparison unit 7, second memory unit 8. Comparison unit 7 contains the first and second registers 9 and 1O, the first and second electrons of AND 11 and 12, the OR element 13 and the adder 14. The execution of block 7 of the amp & n comparison provides a comparison with the integer / number. Block 2 subtraction implemented by the standard subtraction scheme. The second memory block 8 is executed in the form of a register. The device works as follows. Tara with parts installed on digital scales. 1. Parts are linked. The number of links is known, and the number of parts in each link is the same in and unknown. The digital code corresponding to the weight of the P parts in the container is output from the digital balance 1 to the course of the first memory block 8 and is memorized. A certain number of bindings are removed from the container, for example one. The new value of parts weight in tare P is measured. This value from the output of digital scales 1 is fed to the first input of block 2 of the subtraction, the second turn of which receives information about EU P from the new block 8 of memory, the variability (P.) goes to the first the stroke of the 3 dividing unit, the second input of the coordinate of the successively, is yn) c a tion about the weight of the parts, stored with the first memory block 6. The result of the division is analyzed by the first comparison unit 7 and is rounded up to the whole as follows. The fractional part of the result of the division is fed through the first register 9 to the first element 11, and also inverted to the second element 12. In that case. when the result of dividing with the inaccurate precision corresponds to an integer, the signal corresponding to a logical unit is generated at the output of the OR 13 element. By this signal, the information corresponding to the tsegae part of the result of the division is recorded in the second register 10. If the result of the division approaches the whole number to the left with the selected accuracy, then as a result of rounding the value stored by the second register 1O must be increased by one. For this, information from the second register 10 is fed to the first input of the adder 14, the second input of which receives information from the first And 11 element. Comparison unit 7 generates a control at the first input when the result of the divisions corresponds to an integer. This occurs when the difference (P-j-Pg) is divided by the weight of the part of the type that is in the container. In this way, the recognition of the type of part is carried out. At the information input of the comparator unit 7, a digital code is generated corresponding to the number of parts in conjunction. This information is fed to the second input of the digital tabo 4. By the signal from the comparison block 7, the first memory block b generates information. The information about the type of parts, which goes to the third input of the digital scoreboard 4. Information about the number of links is entered from the information input block 5 and goes to the third input of the 3 division block, which determines the value 4 - and divides this value by the number of parts in the link . it

The part corresponds to the number of parts in the container and is fed to the first input of the digital display 4. Information about the weight and type of the part is written to the first memory block 6 for all the parts before the device operates. This is a formation. is entered from the block 5 input information and can be changed by changing the nomenclature of parts.

In the proposed device, recognition is performed automatically by comparing the result of dividing the difference (P -Pj) by the weight of all the possible parts,: fanned by the first memory block with an integer. This eliminates the error in the identification.

The proposed device allows one to take into account parts in any container, and the tare weight is unknown. The consideration of parts in a container is based on the fact that the link between parts makes up a certain proportion of the total number of parts.

The economic effect of using the proposed device is to expand the field of application of the device, which allows its use in places where previously the process was not automated.
