Among the figure: frame 1, arrangement arrangement belt conveyor 2, leading portion arrangement collating unit 3, detection sorting belt conveyor 4, photoelectric detection system are correlation photoelectric sensor 5, selecting device is jet thrust 6, transmitter 51, light receiving device 52, bent frame 7, connection seat 8, turning knob 9, screw rod 10, guide rod 11, fruit 12 automatically.
The specific embodiment
The fruit grader of present embodiment is mainly by frame and dress two sections orthoscopic flat belt conveyers thereon, and photoelectric detection system is with selecting device, leading portion arrangement collating unit three parts are formed automatically.
The fruit grader of present embodiment as can be seen from FIG., by frame, arrangement arrange thereon leading portion arrangement collating unit of belt conveyor and dress, detect sorting belt conveyor and dress thereon, totally two covers photoelectric detection systems and automatically selecting device form; There is control line to be electrically connected between photoelectric detection system and the automatic selecting device; The discharging termination that belt conveyor is arranged in arrangement detects sorting belt conveyor feed end.
The leading portion arrangement collating unit of this machine is the shaped as frame structure at the no end, and fruit directly is deposited on the belt.The preceding deckle board of shaped as frame structure is designed to the oscillatory type guide plate, and tilt to make and narrow the exit passageway of single fruit of to advance below the frame front, arrangement is arranged belt conveyor and is designed to low early and high after tilting layout, and during work, the relative feedstock direction of control conveyer belt drives in the wrong direction.When making fruit enter conveyer, gravitate is rolled forward along the inclined-plane, meanwhile be subjected to the active force of the retrograde direction of belt, under the comprehensive function of these two power, rolled the motion that moves after doing again before one of fruit formation has both been done.
Photoelectric detection system such as Fig. 2 of this machine show, the design classification levels is a secondary, the outer product (fruit that diameter is too little) of level are by blowpit output, so photoelectric detection system adopted two to overlap the correlation photoelectric sensors, set gradually first rank and second level along throughput direction.The correlation photoelectric sensor comprises optical system, amplifier and switching value output device, and its main body comprises and being separated from each other and transmitter and light receiving device two parts staggered relatively, is assemblied in the both sides (showing as Fig. 3) of lining up passage.During work, produce a branch of light modulated that detects light of serving as by transmitter, in the time of between object to be detected is through transmitter and light receiving device, its diameter greater than the light beam height then can moment break beam, thereby the light intensity that causes light receiving device to receive changes, its changing value trigger switch signal output realizes measuring ability.Because this eedle detects classification to the fruitlet product, the inter-stage difference generally has only 2～3mm, and it is as far as possible little therefore must to control the diameter that detects light, to guarantee accuracy of detection.For this reason, disposed special-purpose hole plate behind the lens of correlation photoelectric sensor, the diameter of control emission light beam only is 0.5mm.As shown in Figure 3, the vertical paper of the direction of motion of conveyer belt, transmitter and light receiving device opposition are installed on the bent frame 7, and bent frame and connection seat 8 are fastening.Turning knob 9 can make connection seat and bent frame move up and down by screw rod 10, thereby regulate to detect light beam from the distance of carrying zone face, i.e. the rank size of She Dinging, and the effect of guide rod 11 is that the bent frame of assurance always is in parastate when moving.This machine is provided with two ranks, must guarantee the first order set detect light beam from the distance of carrying zone face greater than the second level.
The automatic selecting device of this machine is because at the fruitlet classification, therefore employing is that the jet thrust of power is automatic selecting device (also can adopt modes such as pneumatic or electronic plectrum certainly) with compressed air.As shown in Figures 2 and 3, jet thrust is right after photoelectric detection system and installs, and accepts detection signal and moves, and source of the gas is connected or closed to two jet thrusts according to the classification instruction.When tested lichee passes through to measure ray, trigger photosignal, start corresponding shower nozzle action, fruit is blown into suitable rank ranks.When the fruit measured value was the outer product of level, two jet thrusts were disconnected source of the gas, and the fruit craspedodrome draws off.
The course of work of present embodiment is: arrange on the belt conveyor in arrangement, at first fruit is arranged by arrangement and is formed the single operation of lining up, and forms certain intervals between each fruit of fast official post by two belt conveyors when entering measurement zone.Line up at fruit on the passage of process, by minute progression the correlation photoelectric sensor of respective numbers is set along traffic direction, the tiny light beam of control sensor level emission, light beam is from the height-adjustable of plane conveyer belt,, be provided with from high to low as " railing " with light beam.When fruit operation during by first order light beam, diameter will block light beam and excitation signal greater than the fruit of light beam height, make the action of first order jet thrust, the formation and send into other output channel of the first order of rapidly it being blown off; The fruit of minor diameter then passes under first order light beam, enters second level beam detection then, can reach the purpose that detects fruit appearance and size and realize classification according to this.
This equipment adopts Photoelectric Detection and the jet technology that sorts to have obvious advantage, and is widely applicable, adjust flexibly, Both can stop mechanical classification and easily cause the generation of hindering the fruit phenomenon, and can realize again at a high speed dynamic on-line measurement and choosing Not.
