During work, the lateral surface lower end of stopping means, microswitch, the second outer toroid is all placed on the ground, and the upper end of spring is hung up, make thus to reserve gap between the lateral surface lower end of the first outer toroid and microswitch.Then, at each side placement collecting box of semicircle feeder, being positioned at collecting box on the left of semicircle feeder for collecting recyclable goods and materials, being positioned at collecting box on the right side of semicircle feeder for collecting not Recyclable money.Then, opened by each ultrasonic sensor, each ultrasonic sensor starts to find range thus.Specific works process is as follows: when not having waste and old material to put in semicircle feeder, and the initial distance recorded (namely this initial distance equals the distance between the medial surface lower end of ultrasonic sensor and semicircle feeder) is sent to microprocessor by each ultrasonic sensor separately in real time.Now, microswitch is in off-state, and microprocessor reads the state of microswitch in real time.When there being waste and old material to put in semicircle feeder, be positioned at the distance that the multiple ultrasonic sensors directly over waste and old material record all to change, the distance recorded is sent to microprocessor by above-mentioned multiple ultrasonic sensor separately in real time, microprocessor calculates the difference between the distance after change and initial distance thus, and the diameter (namely this difference equals the diameter of waste and old material) of waste and old material is judged according to this difference, then the diameter of waste and old material and setting value are compared, judge whether the diameter of waste and old material transfinites according to comparative result thus.Meanwhile, microprocessor is according to the length (namely the distance between the ultrasonic sensor that in above-mentioned multiple ultrasonic sensor, position is the most forward and position ultrasonic sensor the most rearward equals the length of waste and old material) of the range estimation waste and old material between the most forward ultrasonic sensor in position in above-mentioned multiple ultrasonic sensor and position ultrasonic sensor the most rearward, and the length of waste and old material and setting value are compared, judge whether the length of waste and old material transfinites according to comparative result thus.Now, under the weight effect of waste and old material, the front end of semicircle feeder moves down, and is moved down by dynamic first outer toroid of ring belt in first, the first outer toroid and then drive spring to extend downwards by bracing wire.If the lateral surface lower end of the first outer toroid does not touch microswitch, then microswitch is still in off-state, according to the state of microswitch, microprocessor judges that the weight of waste and old material does not transfinite.Otherwise if the lateral surface lower end of the first outer toroid touches microswitch, then microswitch closes, according to the state of microswitch, microprocessor judges that the weight of waste and old material transfinites.When the diameter of waste and old material, length, weight all do not transfinite, namely microprocessor judges that waste and old material is as recyclable goods and materials.Now, microprocessor sends left rotaring signal to motor driver, motor driver controls motor according to left rotaring signal and turns left, motor drives semicircle feeder to overturn left by annulus in annulus, inner screw, second in driving disk, first successively, and waste and old material is poured into the collecting box be positioned on the left of semicircle feeder by semicircle feeder thus.When any one in the diameter of waste and old material, length, weight transfinites, namely microprocessor judges that waste and old material is as not Recyclable money.Now, microprocessor sends right turn signal to motor driver, motor driver controls motor according to right turn signal and turns right, motor drives semicircle feeder to overturn to the right by annulus in annulus, inner screw, second in driving disk, first successively, and waste and old material is poured into the collecting box be positioned on the right side of semicircle feeder by semicircle feeder thus.Based on said process, a kind of goods and materials recognition device based on ultrasonic listening of the present invention, by adopting ultrasonic listening principle, achieves and identifies waste and old material.Compared with radio frequency identification technology, radio frequency+recognition technology of weighing, a kind of goods and materials recognition device based on ultrasonic listening of the present invention is without the need to waste and old material with bar code, and can carry out the identification of waste and old material, therefore its scope of application is no longer limited.Compared with Material Identification technology, a kind of goods and materials recognition device based on ultrasonic listening of the present invention realizes that cost is lower, technical difficulty is less, recognition efficiency is higher.
The present invention is rational in infrastructure, it is ingenious to design, efficiently solve the existing waste and old material recognition technology scope of application limited, realize the problem that cost is high, technical difficulty is large, recognition efficiency is low, be applicable to waste and old material and reclaim.
