Application of automatic weight sorting in packaging logistics quality inspection (III)

3.3.2 non automatic operation (static)

(1 production line for 1000 tons of energy storage, 1 production line for power lithium manganate and 1 production line for 800 tons of water battery cathode material) maximum allowable error of non automatic operation (static)

for loads greater than or equal to the minimum weighing (min) and less than or equal to the maximum weighing (max) when X-type and Y-type weighing instruments are not automatic (static) operation, The maximum allowable error of rapid adjustment for the convenience of the experimental space is as follows:

Table 8

(2) non automatic operation (static) test load

in the influence factor test, the selection principle of non automatic operation (static) test load is as follows:

test load is added from zero to max, and unloaded to zero by similar methods. When determining the initial essential error, at least ten different load points should be selected, and at least five different load points should be selected for other weighing tests. The selection of test load shall include the load of Max, min and the turning point of maximum allowable error (but not above the turning point)

4. Selection principle of sorting scales

the following is a discussion on how to accurately select and use sorting scales in combination with some of the latest sorting scale products launched by Yamato Daiwa checks and balances Co., Ltd. Firstly, the parameters of some series of Yamato products are listed as follows:

when selecting the sorting scale, the most important of the above parameters is:

(1) the relationship between weighing range and accuracy:

from the above table, it can be seen that the larger the weighing specification is (K has a small performance improvement g) the worse the accuracy is (± 10 g) the smaller the weighing specification is (0.g) the higher the accuracy is (± 0.02 g)

(2) the relationship between the measurement speed, length and accuracy of the measured object:

now take csh06l sorting scale as an example, the relationship between speed, length and accuracy is shown in the following chart:

(3) the length and width of the measuring belt are related to the weighing range and sorting accuracy

it can be seen from the above table that when the weighing specification is large (kg), the metering belt is 1.1m long and 0.6m wide, and the sorting accuracy is low (± 10 g); The weighing specification is hour (0.g), the measuring belt is 0.65M long and 0.22m wide, and the sorting accuracy is high (± 0.02 g)
