Abstract
The invention discloses the method and apparatus of weighing apparatus self-poise new technology, it is by the different imbalance action of uneven parts, connects different power supplys to motor, make it to produce different duties, and always scale thallium tuning balance weight position is realized.Its technical advantage is: avoided spring, the influence in hysteresis, creep, the temperature difference and acceleration of gravity four mistake sources that the spring balance of sensor production and electronic scales are intrinsic goes for various weighing apparatus, in order to improve precision and to become hundred times reduce cost.
Description
The present invention relates to a kind of weighing apparatus automatic balancing technology.Self-poise need not manually be adjusted after promptly referring to put into article, just can obtain its value.
General weighing utensil can not be finished self-poise, after putting article, after need people wage adjustment thallium makes it balance, just can get and read value.This title is not easy to raise the efficiency, and uses inconvenient.Present most weighing apparatus is can not self balancingly to claim like this, promptly common mechanical formula table scale, case claim, claim, huge title or the like.
People adopt spring or elastic body to make spring balance and sensor element in order to realize self-poise, and sensor can be assembled into electronic scale.Till now, can finish self balancing have only electronic scale and spring balance.But because the self-poise parts that spring and elastic body are done, natural, intrinsic, unavoidable existence four mistakes source, i.e. hysteresis, the temperature difference, creep and acceleration of gravity.Cause the inaccessible requirement of spring balance precision like this, market and government can not accept, and electronic scale still is being subjected to expensive, the highly difficult less sensor of foozle that goes, so that realize self-poise.Book number is 15210120, and title is " a counter scale platform balance on-ground weigher ", and the 61st page of 5,6 row introduced: the measuring accuracy of strain-type force sensor is generally about 0.2% of maximum capacity.186 pages of introductions of this book: the electronic scale general precision is the per mille of limit weighing.61 pages of this books are introduced the sensor error same spring of originating.58 pages of structure and principles of having introduced force cell of this book.184 pages have been introduced the spring balance general precision is one of three percentages.Sensor device cost height again, each unit up to ten thousand of ton utmost point position.2200 yuan of the electronics counter scale prices of 15 kilograms of maximum dose, prime cost also is sensor.
The object of the present invention is to provide a kind of new method, it not only can finish self-poise, and has avoided the four mistakes source of spring balance and electronic scales, possesses again that cost is low, the advantage of easy manufacturing.
The present invention is achieved in that (one) inventive method.It is independent claims one, characteristic.By on can not the basis of self-poise weighing apparatus, the imbalance action that utilization may produce uneven action component be signalizing activity, with motor connecting power, by the motor power effect, will claim that thallium is displaced to the thallium position of weighing apparatus balance.(2) invention equipment.It is independent claims two, characteristic, as shown in drawings, in this device, (1) is the uneven weighing apparatus parts of possible, (2) be the article quality point of force application, (3) be supporting-point, pulley 01,02 is assembled together with (one), on interlock string (four) is arranged, point (five) or point (six) are fixed string and thallium, (7) be motor, 02 is its driving wheel, and (eight) are the motor connector lug, and (nine) are thallium, power supply the end of a thread is contained on the weighing apparatus with motor the end of a thread is corresponding, and each the end of a thread contact point can be a plurality of.When imbalance, swing up and down as (one), just connect the power supply of a mode to motor, the just clockwise or reversing of motor, one may be thallium to be transferred cause the balance of plant outage, one may be to transfer more uneven and more uneven, and the point of fixity (five), (six) that at this moment change electric power polarity or exchange string and thallium get final product, so realized self-poise.
Because the present invention's spring of no use, so electronic scale that the sensor of doing than existing and only spring balance, with spring is made, hysteresis, creep have been avoided, the temperature difference, acceleration of gravity four mistakes source, (the spring balance general precision is 1/300th to have improved precision, the sensor general precision is 1/500th, and machinery claims generally 1/2000th, can reach 1/10000th, the present invention does not influence its precision after it is implemented), (electronic scale need get final product for 20 yuan and implement the present invention with the sensor about 1000 yuan with having reduced cost.）。
Claims (7)
1, weighing apparatus automatic balancing method, by on can not the basis of self-poise weighing apparatus, it is characterized in that: utilize weighing apparatus may produce the parts of uneven action, the different uneven action of being done, as signalizing activity, motor is connected different power supplys, will claim thallium to be transferred to by motor power and can make it the balance weight position.
2, by can not self-poise weighing apparatus parts (), article force (two), supporting-point (three), pulley 01,02, string (four), tie point (five), (six), motor (seven), connector lug (eight), thallium (nine) and corresponding power connection, in the weighing apparatus automatic balancing arrangement that is constituted, it is characterized in that:
