Wherein, the benchmark scale needs periodic calibrating to guarantee to check precision, concrete can be for passing through " conveying in kind, static weighing " method, " conveying in kind, static weighing ", refer to actual material and carry a time period by the belted electronic balance of being checked, again this time period is carried to material static scale weighing in the past, the numerical value that the static scale weighing of take draws is standard value, and the belted electronic balance of being checked is carried out to the correlation parameter adjustment.Regularly Fast Calibration benchmark scale, demarcate once in general every 24 hours, and benchmark scale feed stream can be recognized people for fixed, and the actual accumulative total of benchmark scale inventory is that benchmark claims the accumulative total recorded inventory.
Belted electronic balance check method provided by the present invention while specifically implementing is after each belted electronic balance of mass transport production line, if the benchmark scale of a periodic calibrating, at belted electronic balance, move on metastable basis, adopt the on-line fine of fixed intervals, the single-candidate compensation method, check successively each belted electronic balance, can realize that belted electronic balance is to realize online check, guaranteed efficiency material conveying production, and to accidental restraining factors, (belt moves by " the online check " and " N circulation ", the discharging fluctuation, material loss etc.) carry out suitable defect elimination processing, improved the check precision.
Wherein, check time T
3=belted electronic balance gauge length/belt travelling speed.The belted electronic balance gauge length refers to the length that belted electronic balance can measure, due to belted electronic balance, be that a weighing face carries out weighing when the weighing, therefore, during belt movement, be process from a weighing face, therefore, have a belted electronic balance gauge length, the belted electronic balance gauge length is belt elapsed time on belted electronic balance divided by the belt travelling speed, and this time is decided to be to the check time T
3, be very rational, can meet more easily the single-candidate compensation, more easily operation, and be minimum check time T
3chronomere, can further improve the check precision.
Check precision in order further to improve, fine setting allowance M
1be not more than error amount, the material stream * technique permissible error of described error amount=Belt Conveying material.The technique permissible error refers to the technique permissible error of the material stream of Belt Conveying material, if fine setting allowance M
1surpass this error amount, can affect the batching quality because of the school scale.Any automatic blending production line has certain allowable fluctuation range, exceeds allowable fluctuation range off quality for batching.
In order further to improve and to check precision, total degree N is not less than the standard number of times of setting, described standard number of times=belt total length/belt travelling speed/check time T
3.The belt total length divided by the belt travelling speed after again divided by checking time T
3what obtain is the number of times of belt while rotating a circle, this number of times is decided to be to the standard number of times, total degree N is not less than the standard number of times of setting, namely whole check process belt at least will rotate a circle, the result drawn like this is just more accurate, otherwise belt rotates the words that are less than a circle, check process so is incomplete, and consider that whole check process belt rotates the words of multi-turn, be not easy to accomplish the single-candidate compensation, and the degree of accuracy of checking can reduce, therefore, recommend total degree N=belt total length/belt travelling speed/check time T
3, whole check process belt only rotates a circle.
Wherein, check value B can be 0.3%, and certainly, check value B can also be other numerical value, and the actual conditions such as check precision that the error that need to allow according to the material of actual belt delivery and the belted electronic balance of being checked need are determined.
