Description
Technical field
This utility model relates to batching weighing systems technology field, is specifically related to a kind of batching weighing control system by traffic monitoring.
Background technology
In automatic blending material and weighing system, the control for proportioning accuracy is mainly from various automatic feeders, and system requirements batcher starts feeding operation according to the requirement of program, when reaching formula numerical value, stops reinforced in time, accomplishes that every order is executed without fail.Desirably controlling effect is that feeding operation stops at formula numerical value, but, actual situation is when the material weighed arrives formula value, although after stopped the feeding operation of batcher, effect due to inertia, air suspension material still can fall into weighing station, dispensing will be caused overproof if magnitude is excessive, it is possible to produce waste material.In the art, during reinforced stopping, aerial suspended material is normally referred to as PR value in dispensing operation, by above-mentioned analysis it can be seen that Aggregate Feeding Error comes from PR value.
Dynamic accuracy comes from the Coordination Treatment mode stopping feeding in raw material.Obviously, system exceeds range of error, will imply that this dispensing is waste material.When stopping reinforced, can there is PR value in the air, it is desirable to method exactly when weighing station distance formula value also has PR to measure, it is reinforced that system stops batcher in advance, if we determined that formula value is W, weighing process values is R1, when stopping reinforced, the air suspension material of overshoot is PR, and stopping reinforced rear final weighing value is R2, i.e. R2=PR+R1, perfect condition is, R2=W, or R2Within the W range of error allowed, it will be so a high-quality batching weighing system.
Feed proportioning system of the prior art adopts double speed or multi-speed charging control mode mostly, and fast reinforced and slow feeding in raw material combines, and its starting point is: when close to formula setting value, by changing charging rate, to reduce the impact to terminating dispensing of the excessive flow.Generally adopting the setting means of PR value, its method is: by experience or by, after the overproof results contrast of the setting of last time suspension amount and dispensing, being automatically modified, PR value be input in system as a fixing setting value.But there is problems of, PR value is an entire variable, the extrinsic factor such as PR value can be pressed along with the outlet storehouse of material, material property and batcher driving voltage and change.If PR value is processed as setting value, will be unable to adapt to the environment of change and all kinds of interference factors, cause the fluctuation of dispensing result, thus dynamic accuracy cannot quantify to ensure, if adopting the automatic correcting mode of overproof generation, owing to the purely retarded of this correction operates (after error generation, be just adjusted) according to error, proportioning accuracy is then in concussion state, and system will be a time-dependent system.
Utility model content
This utility model is in order to solve above-mentioned technical problem, provide a kind of batching weighing that ensure that dynamic accuracy and control system, suspended material can be carried out quantification treatment exactly by this system, after ensureing that suspended material falls into, will accurately and strictly by weighed amount control within range of error, reach the purpose of non differential regulation.
This utility model is the technical scheme that solution the problems referred to above adopt: a kind of batching weighing control system by traffic monitoring, including controller, feed bin, it is positioned at the activation funnel of bin bottom, it is correspondingly arranged at the batcher below activation funnel and the weighing station of accepting setting corresponding to batcher discharge end, described weighing station includes material-compound tank and Weighing control instrument, the centrage to material-compound tank is rectified in the discharging of batcher, and material-compound tank outer wall is provided with Weighing module, material-compound tank is provided with for measuring in batcher discharge end and material-compound tank the range finder module of vertical dimension between material upper surface, Weighing module is connected with Weighing control instrument by same rosette with range finder module, Weighing control instrument is electrically connected with described controller by fieldbus, controller controls the feeding coal of batcher according to the real time data that Weighing module and range finder module transmit.
In this utility model, material-compound tank outer wall is provided with three bearings along its circumference uniform intervals, and each bearing is correspondingly provided with a Weighing module.
In this utility model, described batcher is electro-vibrating feeder.
In batching weighing field, the error of dispensing operation mostlys come from the selection of correct suspension numerical quantity, in other words, be exactly in advance stop feed/discharge time, after the material of air suspension adds, it should accurately within error institute allowed band, and it is also more high to nearer it is to formula setting value proportioning accuracy.In this utility model, controller controls the feeding coal of batcher according to the real time data that Weighing module and range finder module transmit, it is achieved that the purpose of definite value auto feed and definite value automatic discharge.
Beneficial effect: this utility model changes the control structure of the reinforced dual-speed control pattern of tradition, Weighing module and range finder module is adopted to match, vertical dimension between material upper surface in batcher discharge end that controller is measured according to range finder module and material-compound tank, calculate the blanking time, according to blanking speed and blanking time, calculate suspension amount weight, when Weighing module monitor the weighing value of material in material-compound tank deduct suspension amount gravimetric value equal to formula value or within range of error when, controller sends halt instruction, stop batcher immediately to feed in raw material, that is give the weight turned off in advance automatically, owing to flow accurately calculates, enable the system to obtain real-time suspension amount weight data accurately, suspended material can be carried out quantification treatment accurately, with ensure suspended material fall into after will accurately and strictly by Weighting and Controlling within range of error, reach the purpose of non differential regulation, control accuracy is improve 2 ~ 3 times.
