Embodiment:
The object of the present invention is achieved like this: the belt conveyer scale of auto verifying true object, by being set, main weighing frame and secondary measurement bay detect by the weight of belt transport material synchronously, obtain two equal-sized check weighing signals, these two check weighing signals both can independently be exported, by independent measurement, it is measured that the mode that can subtract each other again forms composite signal; The belt conveyer scale instrument is by measuring the signal of main weighing frame, and metering and demonstration are by the flow of belt transport material and cumulant; By standard weights counterweight and automatic weight-hoist device are set, come secondary measurement bay is applied the weight of a standard, carry out the standard transmission; Whether the belt conveyer scale instrument meets standard by the weight of measuring on this secondary measurement bay, comes automatic monitoring whether to measure misalignment, and in case find the metering misalignment, just automatic alarm and send checking signal; The belt conveyer scale instrument standard test weight weight of bearing on the secondary measurement bay again is as according to carrying out automatic Verification then, thereby revises the misalignment situation, guarantees the metering accuracy of belt conveyer scale.
Specific as follows:
One main weighing frame and a secondary measurement bay are set, install in the mode of series connection, detect by the weight of belt transport material synchronously, realize obtaining two equal-sized check weighing signals.
When belt transmission of rotation material.Main weighing frame can pass through sensor check weighing and output signal, and secondary measurement bay also can pass through sensor check weighing and output signal.And since material be with the same weight of same state simultaneously by main weighing frame and secondary measurement bay, so the situation that their experience is identical.Can make in the identical situation of carrying by adjusting, their check weighing signal magnitude equates, and has nothing to do with factors such as mass flow size variation and belt tension variations.
These two check weighing signals both can independently be exported, and by independent measurement, it is measured that the mode that can subtract each other again forms composite signal.Composite signal=secondary measurement bay signal-main weighing frame signal.
One metering and circuit plate is set, when belt transmission of rotation material, by measuring the output signal of main weighing frame load cell, measures and show by the flow of belt transport material and cumulant.So just realized the metering of belt conveyer scale.
One standard round bar counterweight is set, transmits through the balance standard, can determine its standard weights.When standard round bar counterweight is loaded on the secondary measurement bay, just makes secondary measurement bay bear one and stablize constant standard weights like this.
Arrange one by electric pushrod, counterweight is placed the automatic weight-hoist device of framework and counterweight support bracket composition, so just standard round bar counterweight can be loaded on the secondary measurement bay automatically, secondary measurement bay is applied the weight of standard test weight.So also just realized standard transmission to secondary measurement bay.The standard foundation has been arranged when carrying out automatic verification.
One standard weights detection display and automatic monitoring control circuit board are set, realize by measuring composite signal whether the automatic monitoring belt scale metering is accurate.
Wiring board has a control module, can send signal and make electric pushrod work, carries out automatic link code or unloads code.
Wiring board has a signal synthesis unit, when belt transmission of rotation material, the output signal of main weighing frame load cell and the output signal of secondary measurement bay sensor is synthesized.Because at this moment material is simultaneously by main weighing frame and secondary measurement bay with the same weight of same state, therefore their check weighing signal magnitude equates, and irrelevant with factors such as mass flow size variation and belt tension variations, so composite signal=secondary measurement bay check weighing signal-main weighing frame check weighing signal=0.This has just set up a stable online dynamically zero point.If add in addition a weight this moment on secondary measurement bay, then composite signal is non-vanishing.At this moment composite signal=secondary measurement bay check weighing signal-main weighing frame check weighing signal=belt weight of material+add in addition weight-belt weight of material=add in addition weight.Like this, by secondary measurement bay being applied the weight of standard, composite signal is exactly the dynamic standard signal of a corresponding standard round bar counterweight standard weights.Equally, the size of this dynamic standard signal is only relevant with the weight size that secondary measurement bay is applied, and has nothing to do with the size variation of mass flow and the factors such as variation of belt tension.
Therefore, when belt transmission of rotation material, composite signal is zero.When standard round bar counterweight is loaded on the secondary measurement bay, the composite signal correspondence be exactly the standard weights of standard round bar counterweight.So at this moment whether meet standard as long as detect in real time composite signal, whether the weight that just detects on the secondary measurement bay meets standard, just can judge whether belt scale metering is accurate.
Like this, show and the automatic control circuit board that monitors,, just realized whether automatic supervision belt conveyer scale metering is accurate by measuring composite signal by the weight detecting that sets up standard.
In addition, wiring board has the automatic controlling alarm of metering misalignment unit.When by measuring composite signal, when finding belt conveyer scale metering misalignment, can report to the police automatically and send checking signal.
One automatic verification control and standard semi-invariant are set detect the circuit plate, realize carrying out automatically verification by measuring composite signal.
Wiring board has a standard block.By the standard weights of prior input standard round bar counterweight, but corresponding standard accumulation of internal memory unit interval value.As the standard weights of importing standard round bar counterweight is 100kg, standard block with regard to internal memory a time be 20 minutes, standard accumulation value is the standard figures of 300.000t.Other are analogized.Unit interval also can be provided with in advance.
Wiring board has an automatic verification control module.After receiving checking signal, just start-up routine carries out verification.What at this moment wiring board was measured is composite signal, because of standard round bar counterweight is carried on the secondary measurement bay, so the composite signal correspondence is exactly the standard weights of standard round bar counterweight.Wiring board is take this standard weights as detecting according to the verification of accumulating value.
Wiring board has one to compare adjustment unit.The accumulation value of wiring board detection is accumulated value with the standard of prior internal memory compare, and automatically the accumulated value of wiring board detection is adjusted to identical with standard accumulation value.And definite corresponding correction factor.
Then, wiring board sends corresponding control signal starts electric pushrod, standard round bar counterweight is risen secondary measurement bay unloading.At this moment secondary measurement bay is identical with main weighing frame carrying situation again, just carries the belt material.Wiring board sends corresponding control signal again, makes wiring board become the secondary measurement bay signal of detection by measuring composite signal.Wiring board is by detecting, metering and show through secondary measurement bay by the flow of belt transport material and cumulant.
Like this, belt material in transmission of rotation, and metering and circuit plate are measuring and showing through main weighing frame by the flow of belt transport material and cumulant by measuring the output signal of main weighing frame load cell.Automatically verification control and standard semi-invariant detection circuit plate is measuring and is showing through secondary measurement bay by the flow and the semi-invariant of belt transmission material.Because their carrying situation is identical, therefore measurement result should be identical in same time.At this moment, automatic Verification control and standard cumulant detection display wiring board, when metering on one side and showing that the secondary measurement bay of process is by the flow of belt transport material and cumulant, transmit corresponding signal on one side and give metering and the circuit plate of measuring main weighing frame, make it revise measured value, until with own identical.So just revise metering misalignment situation, reached the verification purpose.Whether send signal after complete, make standard weights detection display and automatic monitoring control circuit board start electric pushrod standard round bar counterweight is fallen on the secondary measurement bay of loading, it is accurate to recover the automatic monitoring belt scale metering.
The course of work:
Belt transmission of rotation material, metering and circuit plate are by measuring the output signal of main weighing frame load cell, and metering and demonstration are by the flow of the material of belt transport and cumulant.
Standard weights detection display and automatic monitoring control circuit board are determined dynamic zero point by measuring composite signal.Send signal then and make electric pushrod work, standard round bar counterweight is fallen on the secondary measurement bay of loading.Detect weight conformance with standard whether on the secondary measurement bay in real time by composite signal, monitor automatically whether the belt conveyer scale metering is accurate.In case the metering misalignment is sent checking signal.
Receive checking signal, verification control and standard semi-invariant detection circuit plate start-up routine carries out verification automatically.Carry out the measured value adjustment according to standard accumulation value, until consistent with it.Send signal after complete, make electric pushrod work, standard round bar counterweight is risen, secondary measurement bay unloading, metering and show through secondary measurement bay by the flow of belt transport material and cumulant.Transmit simultaneously corresponding signal and give metering and the circuit plate of measuring main weighing frame, make it revise measured value correction misalignment situation.
After complete, standard weights detection display and automatic monitoring control circuit board start electric pushrod work, and standard round bar counterweight is fallen, and reload on the secondary measurement bay, and whether recover the automatic monitoring belt scale metering accurate.
Owing to implemented such scheme, the physical goods inspection work of belt conveyer scale changed into automatically by the manual type of trouble carried out; Having solved to stop production just can carry out physical goods inspection, does not influence the problem of ordinary production; Make the physical goods inspection resource of having saved energy conservation; Solved in the past physical goods inspection owing to be the not high problem of verification accuracy that factors such as off-line carries out cause; Improved belt conveyer scale accurate measurement reliability.
