Abstract
The utility model relates to a self-checking electronic belt conveyor scale, and relates to the field of the design and manufacturing technology of the electronic belt conveyor scale. A conveyer is provided with a measuring unit and a check unit. A weighting instrument is arranged on a weighting signal transmission lead which is between an A weighting sensor and a B weighting sensor. A check instrument is arranged on a check signal transmission lead which is between a C weighting sensor and a D weighting sensor. A comparison correction machine is arranged between the weighting instrument and the check instrument. The operating principle of the self-checking electronic belt conveyor scale is that the measuring unit is a daily measurement data acquisition zone of the electronic belt conveyor scale, and the check unit corrects the data acquired by the measuring unit through the data acquisition of a weighting section. The data of the electronic belt conveyor scale are displayed after basic data acquisition, transmission, analysis, and calculation. The utility model has a simple structure and a reasonable design. Because of the check unit, the belt conveyor scale can complete the automatic check and correction in a normal operation mode, thus saving troubles, like a parking check, guaranteeing normal production and maintaining measuring precision. The utility model is an ideal self-checking electronic belt conveyor scale.
Description
Technical field
The utility model relates to the design and the manufacturing technology field of belted electronic balance.
Background technology
Belted electronic balance is a kind of dynamic weighing equipment, and its structure is to have measuring apparatus and LOAD CELLS in band conveyor inside.Material can be noted the weight of material automatically during work when this section of process is regional.And have belted electronic balance now in actual motion, and the factor that influences the weighing degree of accuracy is a lot, and drift in various degree in use can take place in the zero point of belted electronic balance and range, so need daily frequent maintenance, could guarantee the normal operation of belt conveyer scale.The cycle of verification decides according to different field requirement, checks one time zero point general every day, range of adjustment in every month.But a lot of industry spot all are whole year productions in 24 hours, can not shut down the verification work of doing a series of complexity; so not only increase user's labor capacity greatly; output also seriously influences production, so if just cause and want to guarantee measuring accuracy in the reality, just can not get guaranteeing so.If guarantee that measuring accuracy of output just can not get guaranteeing.
Summary of the invention
At above-mentioned situation, but the purpose of this utility model provides a kind of belted electronic balance of self-checking, to guarantee production output and measuring accuracy.
Structure of the present utility model is as shown in drawings: have the mass transport belt on belt roller.Have the A LOAD CELLS in the bottom of inboard weighing carrier roller.At the bottom of outside weighing carrier roller band B weighing carrier roller.A, B LOAD CELLS constitute metering units of the present utility model.At a distance of 2~3 groups of carrying roller positions of metering units, have the C LOAD CELLS in inboard verification carrying roller bottom, have the D LOAD CELLS in the bottom of outside verification carrying roller.One standard test weight is respectively arranged on the roller rack both sides.Constitute verification unit of the present utility model by C LOAD CELLS, D LOAD CELLS and standard test weight.Between A LOAD CELLS and B LOAD CELLS, have the weighing-up wave transfer wire, a weighing instrument is arranged on the lead.Between C LOAD CELLS and D LOAD CELLS, have the checking signal transfer wire, a check meter is arranged on the lead.One contrast straightener is arranged between weighing instrument and the check meter.On the rate signal incoming line of weighing instrument and check meter a tachogenerator is arranged.The utility model is made of metering units and verification unit and belt conveyor, and two unit have weighing section separately.Its principle of work is: metering units is the daily measurement data acquisition of belted electronic balance district, and verification unit is revised the data that metering units is gathered by gathering the data on its weighing section.Metering units and verification unit are worked simultaneously under the regular situation, all be to gather baseband signal, deliver to simultaneously in weighing instrument and the check meter gathering the weight signal and the rate signal that come, instrument is calculated data, show the belt conveyer scale data, and with data deliver to that the comparison straightener is stored, printing etc.In such cases two covers weigh part can be standby each other, a cover when fault occurring wherein another set ofly still can carry out weighing to material, stays with adequate time another set of device is overhauled, and can not influence ordinary production.When finding the belt conveyer scale precise decreasing, in the time of need carrying out verification to it, metering units remains the work of weighing normally, and verification unit then is that metering units is carried out verification.On the extension counterweight frame of verification unit, apply the standard test weight of constant weight, at this moment the weight that detects of verification unit then is normal weight of material and the weight sum of the counterweight that is applied, check meter is given the comparison straightener with this signal, the comparison straightener by to the collection of weighing instrument and check meter signal, analyze, calculate added value with respect to the actual detected material.This added value is the foundation that symmetrical tuple certificate is made amendment, and by the increase and the minimizing of criterion value, then the data in the weighing instrument is revised.Reach on-line automatic verification of belted electronic balance and correction.The utility model is simple in structure, and is reasonable in design.Owing to have verification unit, make belt conveyer scale can under normal operation, finish automatic verification, revise automatically, saved many troubles such as parking verification, can guarantee ordinary production, can keep measuring accuracy again.It is a kind of desirable self checking belted electronic balance.
