Abstract
The invention discloses an error control method of a weighing machine. The weighing machine comprises a feeding pipe, a weighing hopper and a master controller. Materials are discharged from the feeding pipe to the weighing hopper, and height fall exists. After feeding is completed, residual materials still exist in the air and do not fall into the weighing hopper, and errors are caused by excessive material discharging. Before the electronic weighing machine is started, a fall correction value is input through the master controller, the weight obtained through weighing of the weighing hopper is equal to a value obtained by subtracting the fall correction value from a final target weight value, a feeding valve of the feeding pipe is closed through the controller, feeding is stopped, the remaining weight is supplemented through the materials in the fall air, and accuracy is guaranteed.
Description
Technical field
The present invention relates to material metage packaging field, specifically a kind of error control method of weighing machine.
Background technology
At packaging field, material needs, first through weighing, then to enter in packaging bag and carrying out package encapsulation.But current weighing-appliance, major part is all adopt simple scale hooper to weigh, and structure is simple, easy to use, but weighing precision is not high, and cause weighting error comparatively large, qualification rate is lower.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of error control method of weighing machine, before weighing, arranges drop correction, ensures the precision weighed.
Technical scheme of the present invention is:
An error control method for weighing machine, weighing machine includes feeding pipeline, weighing bucket and master controller; Feeder channel has height fall to weighing bucket blanking, after feed terminates, still have salvage stores also not fall into weighing bucket in the air, then can form many blankings and cause error, before projection electronic weighing machine starts, by master controller input drop correction, when the weight that scale hooper claims reach ultimate aim gravimetric value deduct drop correction time, controller cuts out the feed valve of feeding pipeline, stops feed, remaining weight is filled by the material that drop is aerial, ensures precision.
Described master controller is connected with annunciator; Before projection electronic weighing machine starts, operating personal is reported to the police upper partially value and lower value partially of reporting to the police by master controller input, partially be worth under the warning that the weight that the weight claimed when scale hooper claims is greater than setting is worth or is less than the warning of setting partially, master controller drives annunciator Realtime Alerts, reminds nonconformity of weighing.
Advantage of the present invention:
The present invention is provided with drop correction, when the weight that scale hooper claims reach ultimate aim gravimetric value deduct drop correction time, controller cuts out the feed valve of feeding pipeline, and stop feed, remaining weight is filled by the material that drop is aerial, ensures precision.The present invention is also provided with warning function, once weighing results does not meet setting range, nonconformity of namely weighing, realizes warning function, reminds staff again to weigh, improves the qualification rate of product.
Detailed description of the invention
An error control method for weighing machine, weighing machine includes feeding pipeline, weighing bucket, master controller, the annunciator that is connected with master controller; Feeder channel has height fall to weighing bucket blanking, after feed terminates, still have salvage stores also not fall into weighing bucket in the air, then can form many blankings and cause error, before projection electronic weighing machine starts, by master controller input drop correction, warning being worth partially and lower value partially of reporting to the police, when the weight that scale hooper claims reach ultimate aim gravimetric value deduct drop correction time, controller cuts out the feed valve of feeding pipeline, stops feed, remaining weight is filled by the material that drop is aerial, ensures precision; Partially be worth under the warning that the weight that the weight claimed when scale hooper claims is greater than setting is worth or is less than the warning of setting partially, master controller drives annunciator Realtime Alerts, reminds nonconformity of weighing.
Claims (2)
1. an error control method for weighing machine, weighing machine includes feeding pipeline, weighing bucket and master controller; It is characterized in that: feeder channel has height fall to weighing bucket blanking, after feed terminates, still have salvage stores also not fall into weighing bucket in the air, then can form many blankings and cause error, before projection electronic weighing machine starts, by master controller input drop correction, when the weight that scale hooper claims reach ultimate aim gravimetric value deduct drop correction time, controller cuts out the feed valve of feeding pipeline, stops feed, remaining weight is filled by the material that drop is aerial, ensures precision.
2. the error control method of a kind of weighing machine according to claim 1, is characterized in that: described master controller is connected with annunciator; Before projection electronic weighing machine starts, operating personal is reported to the police upper partially value and lower value partially of reporting to the police by master controller input, partially be worth under the warning that the weight that the weight claimed when scale hooper claims is greater than setting is worth or is less than the warning of setting partially, master controller drives annunciator Realtime Alerts, reminds nonconformity of weighing.
