Start-stop of the electronic belt scale can be controlled through information of the high-material-position phototubes and the low-material-position phototubes and the control system, flow of a lower machine can be controlled by adjusting the height of the moving door, intermittent and dynamic weighting and measuring can be realized, and accurate measuring and accurate mixing can be realized without influencing preset flow of front and rear equipment, so that the problem of inaccuracy in measuring by the electronic belt scale under the condition of small flow is solved.
Description
Technical field
The present invention relates to material Dynamic Weighing Technology field, in particular for the Dynamic Weighing Technology field under the low discharge situation.
Background technology
Along with each opium factory cigarette producing process is more and more paid attention to the loss of raw material, more and more accurate to the statistical requirements of rejecting thing, the increase of small-scale test line in addition, the flow that is small-scale test line or conventional throwing line rejecting thing is all very little, if come Weighing with the conventional electrical belt conveyer scale, because the mass flow that will measure is too little, the load on the metering section is too light, so metering is inaccurate.So under the low discharge situation, how realizing accurate metering, precisely mixing and just become a difficult problem, be badly in need of a kind of Weighing method that can head it off.
Summary of the invention
The objective of the invention is to solve that mass flow owing to metering is too little, the load on the metering section is too light, provide a kind of for the batch (-type) dynamic weighting system and method under the low discharge situation with the unmeasurable problem of conventional electrical belt conveyer scale.
Purpose of the present invention is achieved through the following technical solutions:
The batch (-type) dynamic weighting system that is used for low discharge, metering system includes feed end buffer memory bucket and the discharge end buffer memory bucket that lays respectively at belted electronic balance feed end and discharge end, differing heights at feed end buffer memory bucket is respectively equipped with high charge level photoelectric tube and low material level photoelectric tube, belted electronic balance has weighing device and control system, the discharging opening of discharge end buffer memory bucket has adjustable for height vertical dodge gate, and high charge level photoelectric tube, low material level photoelectric tube, belted electronic balance, vertical dodge gate are controlled by the control system of belted electronic balance.
The batch (-type) dynamic weighting method that is used for low discharge, when mass flow hour, utilize feed end buffer memory bucket with the supplied materials buffer memory, when material level increases when covering the high charge level photoelectric tube, belted electronic balance starts and carries out dynamic weighting; When material level is reduced to low material level photoelectric tube when exposing, belted electronic balance stops, and so circulation realizes the batch (-type) dynamic weighting; Simultaneously the size of the dodge gate height control discharging opening of control system by adjusting discharge end buffer memory bucket guarantees that the mass flow of slave computer is stable, avoids slave computer fracture to occur or the bed of material is blocked up.
The present invention can be by the start-stop of high charge level photoelectric tube and low material level photoelectric tube information and control system control belted electronic balance, control the flow of slave computer by the height control of dodge gate, realize the batch (-type) dynamic weighting, can not only realize accurate metering, precisely mix, and can not influence the setting flow of front and back equipment.
Adopt the present invention, can when mass flow is big, adopt dynamic conveyor scale metering method; And at mass flow hour, adopt batch (-type) dynamic weighting method, equal substantially to guarantee the load on metering section under the situation of big flow or low discharge, be conducive to improve measuring accuracy, solved under the low discharge situation with the inaccurate problem of belted electronic balance metering.

Embodiment
Further set forth content of the present invention below in conjunction with Figure of description.
As Fig. 1-shown in Figure 4, the present invention is used for the batch (-type) dynamic weighting system of low discharge, by feed end buffer memory bucket 1, belted electronic balance 2,3 three unit of discharge end buffer memory bucket are formed, include the feed end buffer memory bucket 1 and the discharge end buffer memory bucket 3 that lay respectively at belted electronic balance 2 feed ends and discharge end, differing heights at feed end buffer memory bucket 1 is respectively equipped with high charge level photoelectric tube 4 and low material level photoelectric tube 5, the discharging opening of discharge end buffer memory bucket 3 has adjustable for height vertical dodge gate 6, high charge level photoelectric tube 4 and low material level photoelectric tube 5 are a pair of, are arranged at the relative both sides of feed end buffer memory bucket 1 respectively.High charge level photoelectric tube, low material level photoelectric tube, belted electronic balance, vertical dodge gate are controlled by the control system of belted electronic balance.
The batch (-type) dynamic weighting method of system of the present invention is as follows: when mass flow hour, utilize feed end buffer memory bucket 1 with the advanced row cache of supplied materials, when being accumulated to material level gradually, material is increased to when covering high charge level photoelectric tube 4, belted electronic balance 2 starts, and the material in the feed end buffer memory bucket enters belted electronic balance continuously and carries out dynamic weighting; When the material level in the feed end buffer memory bucket is reduced to low material level photoelectric tube 5 when exposing gradually, belted electronic balance 2 stops, and so circulation realizes the batch (-type) dynamic weighting.Simultaneously fracture occurs or the bed of material is blocked up for fear of slave computer, the size of the dodge gate height control discharging opening of control system by adjusting discharge end buffer memory bucket 3 guarantees that the mass flow of slave computer is basicly stable, avoids slave computer fracture to occur or the bed of material is blocked up.Adopt the present invention, when mass flow is big, can realize dynamic continuous weighing metering; And at mass flow hour, can realize the batch (-type) dynamic weighting again.So just can guarantee that the load on metering section under the situation of big flow or low discharge is equal substantially, be conducive to improve measuring accuracy, solve under the low discharge situation with the inaccurate problem of belted electronic balance metering.
