Higher.Weighing-appliance is mainly by load bearing system (such as scale pan, scale body), power transmission converting system (such as lever transmission system, sensor)
It is formed with indicating value system (such as dial, electronic display meter) 3 parts.It weighs in producing and selling are combined, weighs now
Equipment has been a great concern, and the demand of weighing-appliance is also increasing.
Tradition is weighed single usually using sensor-based system, and weighing results float big, affect the stability weighed and accurate
Degree.
Invention content
It is an object of the invention to：It weighs for tradition single usually using sensor-based system, weighing results float greatly, influence
The problem of stability weighed and accuracy, provide a kind of reinspection method of weighing having error compensation.
The present invention specifically uses following technical scheme to achieve the goals above：
A kind of reinspection method of weighing having error compensation comprising following steps：
Step 1：The desired value of the quality of material of external setting-up is deposited into the control system；
Step 2：The given desired value is inputted PLC by the control system, and the PLC, which provides charging signal, makes institute
It states batch charging mechanism to start to feed intake, the motor-driven valve and the vibrating motor are closed at this time；Obtain the first weighing unit
The the first weighing-up wave F1=nqLgcos θ+2TKD1/L sent；Wherein, n is weighing carrier roller group number, and q is close for loaded line of weighing
Degree, L are carrying roller spacing, and g is acceleration of gravity, and θ is Inclination of the conveyer, and T is belt tension, and K is belt stiffness coefficient, D1 the
The non-collimated degree of weighing carrier roller of one weighing unit；
Step 3：The material is accumulated in the hopper, and the pressure that the material generates the hopper is in the title
It retransmits and is changed into the incoming instrument of electric signal in sensor；Obtain the second weighing-up wave F2=nqLgcos θ of the second weighing unit transmission
+2TKD2/L；Wherein, D2 is the non-collimated degree of weighing carrier roller of the second weighing unit；
Step 4：Obtain compensation weighing signal F3=(F1 × D2-F2 × D1)/(D2-D1)；Wherein, D2 ≠ D1；
Step 5：The measured value of the weighing sensor is uploaded to the PLC by the instrument immediately, and the measured value exists
The desired value given with the control system in the PLC is compared, described when the measured value reaches the desired value
PLC, which provides stop signal, makes the batch charging mechanism stopping feed intake；
Step 6：The PLC provides open signal and opens the motor-driven valve, after the motor-driven valve fully opens, institute
Vibrating motor startup is stated, the material of the aimed quality is discharged from hopper.
Further, during the batch charging mechanism adds material to the hopper, when the matter of the material in hopper
When amount is close to required desired value, the control system reduces the rate of feeding of the batch charging mechanism, makes the material in the hopper
Amount accurately reaches required aim parameter.
Further, after the material metage process, the control system automatically turns on the motor-driven valve, waits for institute
It states after motor-driven valve fully opens, starts the vibrating motor automatically.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
Caused result is fluid during the reinspection method elimination of weighing provided by the invention for having error compensation is weighed
Non-linear effects improve weigh accuracy and durability, repeatability.
Specific implementation mode
A kind of reinspection method of weighing having error compensation provided by the invention comprising following steps：
Step 1：The desired value of the quality of material of external setting-up is deposited into control system；
Step 2：Given desired value is inputted PLC by control system, and PLC, which provides charging signal, makes batch charging mechanism start to throw
Material, motor-driven valve and vibrating motor are closed at this time；Obtain the first weighing-up wave F1=of the first weighing unit transmission
nqLgcosθ+2TKD1/L；Wherein, n is weighing carrier roller group number, and q is load line density of weighing, and L is carrying roller spacing, and g adds for gravity
Speed, θ are Inclination of the conveyer, and T is belt tension, and K is belt stiffness coefficient, and D1 is the non-standard of weighing carrier roller of the first weighing unit
Straight degree；
Step 3：Material is accumulated in hopper, and the pressure that material generates hopper is changed into telecommunications in weighing sensor
Number incoming instrument；Obtain the second weighing-up wave F2=nqLgcos θ+2TKD2/L of the second weighing unit transmission；Wherein, D2
The non-collimated degree of weighing carrier roller of two weighing units；
Step 4：Obtain compensation weighing signal F3=(F1 × D2-F2 × D1)/(D2-D1)；Wherein, D2 ≠ D1；
Step 5：The measured value of weighing sensor is uploaded to PLC by instrument immediately, measured value in PLC with control system
Given desired value is compared, and when measured value reaches desired value, PLC, which provides stop signal, makes batch charging mechanism stopping feed intake；
Step 6：PLC provides open signal and opens motor-driven valve, and after motor-driven valve fully opens, vibrating motor starts, will
The material of aimed quality is discharged from hopper.
It should be noted that during batch charging mechanism adds material to hopper, when the quality of material in hopper is close to institute
When needing desired value, control system reduces the rate of feeding of batch charging mechanism, and the inventory in hopper is made accurately to reach required aim parameter.
In addition, after material metage process, control system automatically turns on motor-driven valve, after motor-driven valve fully opens,
