Embodiment:
The object of the present invention is achieved like this: novel calibration equipment, be transmitted the weight of material by set up standard measurement bay and belt conveyer scale weighing frame synchronous detection, obtain two equal-sized check weighing signals, set up the dynamic zero point of check system after signal is synthetic; By the weight code block circle that sets up standard the canonical measure frame is applied the weight of a standard, carry out the standard transmission, set up the verification standard and judgment of check system; To come signal is synthesized by signalization compositor and instrument display, measure and show the standard value of checking data. the standard value that the belt conveyer scale instrument is compared checking data is adjusted, and carries out and finishes physical goods inspection work.
Specific as follows:
One measuring unit is set,, produces two equal-sized check weighing signals with belt conveyer scale weighing frame synchronous detection:
Measuring unit is made up of the canonical measure frame. high-precision sensor is housed above the measurement bay, therefore can check weighing and export the mv electric signal. the weighing frame of belt-like scale. measurement bay is installed in the adjacent place of belt conveyer scale weighing frame to form the mode of connecting with belt conveyer scale weighing frame.
Like this, when belt transmission of rotation material, belt conveyer scale weighing frame can check weighing and output signal, measurement bay also can check weighing and output signal. because material is to pass through belt conveyer scale weighing frame and canonical measure frame simultaneously with the same weight of same state. therefore, the situation of their experience is identical, can make under the identical situation of carrying by adjusting, measurement bay equates with the check weighing signal magnitude of belt conveyer scale weighing frame output. and the output signal of measurement bay directly sends a signal synthesizer to. and the check weighing signal of belt conveyer scale weighing frame had both sent the belt conveyer scale Displaying Meter to and had normally measured, and also sent signal synthesizer simultaneously to. and two signals synthesize at signal synthesizer.
By such setting, neither influencing belt ordinary production transmission material and belt conveyer scale normally measures, simultaneously when belt transmission material, two equal-sized check weighing signals that obtained to produce by being transmitted weight in kind. and irrelevant with factors such as mass flow size variation and belt tension variations.
The signalization synthesis unit synthesizes the check weighing signal of canonical measure frame and belt conveyer scale weighing frame output, sets up the dynamic zero point and the outputting standard signal of check system:
Signal synthesis unit is made up of signal synthesizer. receives from the check weighing signal of canonical measure frame output and the check weighing signal of belt conveyer scale weighing frame output. and compositor adopts subtraction process, two signals are synthesized, form composite signal output. composite signal=measurement bay signal-belt conveyer scale weighing frame signal.
Like this, when belt transmission material, belt conveyer scale can normally measure and carry out work. simultaneously, because material is simultaneously by canonical measure frame and belt conveyer scale weighing frame with the same weight of same state, therefore their carrying is identical, the check weighing signal magnitude equates, so the dynamic zero point of check system has just been set up in their composite signal=canonical measure frame check weighing signal-belt conveyer scale weighing frame check weighing signal=0.. and it has nothing to do with the variation of mass flow size and the factors such as variation of belt tension. be a stable online dynamic zero point therefore, rationally true.
At this moment, if on the canonical measure frame, add a weight in addition, then composite signal is non-vanishing. composite signal=canonical measure frame check weighing signal-belt conveyer scale weighing frame check weighing signal=weight of material+add in addition weight-weight of material=add in addition weight. like this, by the canonical measure frame being applied the weight of standard, signal synthesizer will produce a dynamic standard signal. and same, the size of this dynamic standard signal is only relevant with the weight size that the canonical measure frame is applied, and has nothing to do with the size variation of mass flow and the factors such as variation of belt tension.
Signal synthesizer synthesizes the check weighing signal of canonical measure frame and the output of belt conveyer scale weighing frame on the one hand, forms composite signal output. and simultaneously the check weighing signal of canonical measure frame is independently exported and the check weighing signal of belt conveyer scale weighing frame is independently exported on the other hand. so compositor has three signal outputs. and three signals all send a selector switch to. and selector switch can be selected signal as required for use.
By such setting, neither influence belt ordinary production transmission material and belt conveyer scale and normally measure, can determine online dynamic zero point simultaneously and obtain the dynamic standard signal by the canonical measure frame being applied standard weights. and irrelevant with factors such as mass flow size variation and belt tension variations.
The unit that sets up standard applies standard weights to the canonical measure frame and carries out the standard transmission, sets up the verification standard and judgment of check system:
Standard block is by standard weights code block circle, equipment supporter, compositions such as clearer and standard code block circle lifting control mechanism.
One standard weights code block circle is arranged, weight can be provided with according to the belt conveyer scale specification. and accurately determine by the transmission of balance standard. on hang on the equipment supporter. but pressure is on the material that is transmitted by belt after lowering. when belt rotates, can be with material with belt advanced in unison cycle rotation. the standard weights of oneself is acted on the canonical measure frame, carry out the standard transmission.
The girth of standard weights code block circle is determined, also can determine after as 10m weight by the transmission of balance standard, the average weight of unit length has also just been determined as 123.45kg., average weight as every m is that the concrete parameter of 12.345kg/m can be according to the situation setting of belt conveyer scale. when like this carrying out verification, the verification standard and judgment has just been arranged.
One equipment supporter is arranged, be seated in canonical measure frame position, fixed installation is on the ground. carrying roller is arranged on the support. and can support standard weights code block circle.
One lifting control mechanism is arranged, be fixedly mounted on the equipment supporter. lifting that can control criterion weight code block circle. when carrying out verification work, the code block circle is lowered. at ordinary times, the code block circle gone up accept. do not influence belt transmission material.
One clearer is arranged, be fixedly mounted on the equipment supporter. when carrying out verification work, when the code block circle lowers cycle rotation, clean the code block circle. make the code block circle keep clean, weight standard is unaffected.
By such setting, when carrying out physical goods inspection work, when belt transmission of rotation material, the code block circle lowers pressure on material, with material during with belt advanced in unison cycle rotation, just can apply a standard weights to the canonical measure frame. the check weighing signal that the canonical measure frame is produced is bigger than the signal that belt conveyer scale weighing frame produces. and the ECDC achievement forms the weight signal of a standard. and signal sends instrument to, instrument just can be on this basis, adjust corresponding indicating value. and the weight signal of this standard size is only relevant with the weight of code block circle, and irrelevant with factors such as flow size variation that is transmitted material and belt tension variations. and easy to operate, do not influence the normal metering of production and belt conveyer scale.
Such setting, the standard transmission of making tallies with the actual situation. have authenticity and reliability. and can be under the situation of belt ordinary production transmission material, at various factorss such as mass flow size variation and belt tension variations all is under the actual conditions at scene, carries out verification work. realized real online physical goods inspection.
The signalization selected cell, according to different needs, select corresponding signal output:
The signal selected cell is made up of selector switch. is fixedly mounted on the signal synthesizer. and three signals that the received signal compositor sends. by switch transition, can select, select one of them signal to send instrument to and detect and show three signals.
When carrying out verification work, the instrument that the selection composite signal sends to detects and shows. during tread belt scale weighing frame performance, select the check weighing signal of belt conveyer scale weighing frame output to send instrument to. when calibration equipment used as belt conveyer scale, the check weighing signal of choice criteria measurement bay output sent instrument to.
By such setting, not only make calibration equipment carry out online physical goods inspection work, and can realize using to the test of belt conveyer scale weighing frame performance with as belt conveyer scale to belt conveyer scale.
Be provided with and detect and display unit, signal is detected, and show the standard value of checking data with digital form:
Detect and display unit, to form by instrument display. instrument display is similar to the belt conveyer scale Displaying Meter. accepts from the signal of selector switch and the signal of belt conveyer scale speed pickup. after receiving signal, detect, show the standard value of checking data then with digital form.
When carrying out verification work, instrument display receives that the signal of selector switch is a composite signal. when belt feeder starts, when belt rotates ordinary production transmission material, the instrument display content displayed is dynamic zero point. standard weights code block circle is fallen then, pressure is on material, rotate synchronously with belt with material, the canonical measure frame is applied standard weights, at this moment the instrument display content displayed is that standard weights code block circle rotates flow weight and the semi-invariant that is acted on synchronously with belt.
Instrument display is the same with the belt conveyer scale Displaying Meter, can be provided with. as carry out verification when work, as long as according to the standard weights input respective standard value of belt speed and code block circle, along with the cycle rotation of code block circle, just can adjust the indicating value of semi-invariant according to standard value automatically, until meeting the requirements.
If the check weighing signal of selector switch choice criteria measurement bay sends instrument display to, the code block circle is packed up and is not worked, and at this moment instrument display just can be equivalent to the belt conveyer scale instrument and carries out work. the flow and the semi-invariant of the material that content displayed is transmitted by belt.
So far, owing to be provided with said units, when belt feeder starts the belt running, can ordinary production transmit material, belt conveyer scale can operate as normal measure. and calibration equipment can onlinely carry out physical goods inspection to belt conveyer scale.
The physical goods inspection course of work:
Belt feeder starts, belt works well and produces the transmission material. and the belt conveyer scale operate as normal is measured. open the calibration equipment instrument display, weight according to belt speed and code block circle, standard semi-invariant input instrument display with the unit interval. the code block circle is lowered allows its pressure on material after a while, rotate with the belt synchronous circulation. the semi-invariant indicating value of scope table display. because the calibration equipment instrument display can be adjusted indicating value automatically according to the standard value of input, therefore along with the cycle rotation of code block circle, the indicating value of instrument display is adjusted automatically, make with standard value and conform to. rise the code block circle subsequently. the check weighing signal by selector switch choice criteria measurement bay sends instrument display to, at this moment instrument display is as the belt conveyer scale instrument, the flow and the semi-invariant of the material that demonstration is transmitted by belt. therefore, whether observe the belt conveyer scale instrument indication value conforms to calibration equipment instrument display indicating value. adjust if any difference, until conforming to. and verification work has just been finished like this.
Owing to implemented such scheme, novel calibration equipment can solve present belt conveyer scale and carry out the physical goods inspection existing questions. specifically: all had ready conditions in general production scene belt conveyer scale is carried out physical goods inspection; Can transmit under the situation of material ordinary production and the normal metering of belt conveyer scale at belt, belt conveyer scale is carried out physical goods inspection; Can onlinely carry out physical goods inspection, improve the accuracy of verification belt conveyer scale; Can make the work of belt conveyer scale physical goods inspection convenient and simple, carry out at any time. in addition, because need not be such as vehicle, large-scale weighing machine or lid factory building be built feed bin, and therefore other auxiliary facility such as bunker scale can significantly reduce the expense of physical goods inspection; Owing to be in belt normal transmission material, to carry out verification, do not need the belt feeder free-runing operation, but therefore using electricity wisely more than 90% and devices consume; Also can save time manpower and other social resources.
The online material calibration apparatus for belt scales feature is: one can be in the situation of belt normal transmission material and belt conveyer scale normal operation metering, belt conveyer scale is carried out the device of online physical goods inspection, by equipment supporter, the canonical measure frame, standard weights code block circle, cleaner, standard weights code block circle lifting control mechanism, signal synthesizer, the compositions such as instrument display and selector switch.
