Description
Technical field
The present invention relates to automatic classification method and system, especially but not exclusively relate to the automatic classification of fruits and vegetables.The field of the invention also extends to but the method and system that is not limited to use for, classification separated at rubbish and recirculation, and the method and system using in the separation of the solid granular raw material such as ore and classification.
Background technology
The automatic classification system based on optics at some for fruits and vegetables, product to be sorted is discharged from the end of horizontal conveying belt.Product to be sorted is scanned on conveyer belt time and/or while flying out from conveyor belt ends optically, and makes and accept/abandon decision based on described scanning.As fruit product will be dropped, make it depart from its normal flight track, and deflect into and abandon in slideway.As fruit product will be accepted, it enters and accepts slideway along its undisturbed normal flight track.This is the feature of basic two-way batch operation.
In practice, often need the sort operation of more complexity.Product may must be divided into more than two classes, for example " grade A ", " grade B " and " waste product ", or alternately " acceptance ", " again processing " and " waste product ".Originally these are realized through second sorter by one in two product streams that make to classify from the first two-way compared with complicated sort operation.This needs two different categorizing systems (two light scanning devices, two judgement electronic installations, two ejector devices, two cover transfer systems etc.).Except to product through the relevant cost of twice complete sort operation, this also causes the outer shortcoming of damaging of turnout.
In the prior art shown in Fig. 1, single ejector device 101 is for realizing afterwards three tunnels classification by making level of two ejector devices 102,103 (or this ejector device of two rows) be associated in another.By single optical scanner and judgment means 104, carry out three tunnel classification judgements.When product 110 is during through the first ejector device 102, carry out just subseries, the product of---for example " waste product "---is deflected downwards to dedicated path 107 to be wherein divided into the first kind, and all the other products continue to the second ejector device 103.When product 110 is during through the second ejector device, classify for the second time, the product that is wherein divided into Equations of The Second Kind (for example " grade B ") is deflected in the second dedicated path 108, and the 3rd class (for example " grade A ") not deflection of product advances to Third Road footpath 109.
Do not need two complete sorters, what quantity doubled is only ejector device.Yet this layout still has some shortcomings.Must allow product to fall by larger height so that it is one after the other through two ejector devices.This has increased the possibility of damaging product.And when product arrives the second ejector device, product has fallen more remote, make the control of its exact position and anticipation all more inaccurate.Owing to having increased the quantity of " missing classification " (be such product, this product has been selected as wanting deflection, is but in fact missed by ejector device because product arrives the regularly wrong of ejector device) and reduced the accuracy of the second sort operation.This (is also such product owing to having increased " unexpected classification ", this product is not selected as wanting deflection, truly have arrive the regularly wrong of ejector device with product and in fact by the deflection of ejector device) quantity and reduced the accuracy of the second sort operation.Except these problems, although the cost of this device lower than the equipment with two complete sorters, still has and has two costs that complete ejector device is relevant.And this layout is complicated and is therefore easy to that there was a mechanical failure.
United States Patent (USP) 7041926 relates to the method and system for the stone by the separated gravel aggregate of one or more predetermined characteristic.This is achieved in the following ways, and, gravel aggregate is passed extend through the drop pipe in a plurality of crosspoints that is, and each crosspoint is connected to three outlets: first distributes flexible pipe, second to distribute the extendible portion of flexible pipe and drop pipe.The hinged deflector means of a pair of independence is positioned at place, each crosspoint, and the every pair of deflector means is can co-operating ground hinged, so as to make to intersect in three outlets pointing out only one will open in any given time.Although this layout can be carried out in single position complexity classification, but still must bear cost and the mechanical complexity of two ejector devices.And except the complexity of whole system, this layout also requires the coordination of the motion of the hinged deflector means of two independence.
Therefore, need improved multi-class automatic classification method and system.

The specific embodiment
As mentioned above, Fig. 1 illustrates according to prior art systems San road categorizing system 101.This system for minute type objects 110 comprises conveyer 105, Optical devices 104,102,103 and three independent paths 107,108 and 109 of a pair of two-way ejector device.Object 110 to be sorted is along conveyer 105 carrieds and can drop from the end of conveyer 105, and its freedom of entry falls herein.Because the quality of all given objects to be sorted is followed known distribution conventionally, and because conveyer operates at a predetermined velocity, therefore can estimate the track 106 falling behind under object freedom of entry.Path 107,108 and 109 is arranged in conveyer below, and undeflected free-falling object will be along path 109 be advanced, and the deflection of free-falling object 107 or 108 is advanced by the degree being deflected according to it and along path.
There are the Optical devices 104 in the visual field 111 along track 106 location of estimating, make the object of free-falling will first pass the visual field 111.Optical devices 104 can scan the object through the visual field 111, and whether the object that real-time judge is scanned should be classified in path 107,108 or 109.Optical devices 104 can be passed to dependent instruction ejector device 102,103 then, with the object of guaranteeing to be scanned, are classified in definite path.Ejector device 102,103 guarantees that the object being scanned is correspondingly classified, as mentioned below.
Further along the track 106 of estimating (, after Optical devices), the first two-way ejector device 102 is located so that when in retrieving position, and the object of free-falling will be through device 102, its track not deflection and along path 109 direction advance.When stretching out between in due course in object fall process, ejector device 102 will make the trajectory deflection of object, and it 107 is advanced along path.From Optical devices 104 really earnest body will be along path the instructions of 107 classification will make ejector device stretch out to guarantee that at reasonable time object will be along path 107 advances.If Optical devices determine object and will be along path 108 or 109 advance, this will make ejector device keep regaining.Formal because the path of object free-falling can be estimated, therefore also can estimate to put object along the position of its estimated path in preset time.Like this, can estimate when the first two-way ejector device should stretch out, to guarantee that object is by 107 deflections along path.
Along estimated path 106 further (that is, after Optical devices and the first ejector device) be positioned with the second two-way ejector device 103.Only passed through the first ejector device and the track of the object of not deflection (that is, still 109 direction is advanced and not 107 deflections along path along path) could be by the second ejector device deflection.When the second ejector device is during in retrieving position, through the deflectable object of device 103 will with its undeflected track through and along path, 109 advance.In the dropping process at this object, when reasonable time stretches out, ejector device 103 will make the trajectory deflection of object, and it 108 is advanced along path.As the situation of the first ejector device 102, if free-falling object will 108 deflections along path, Optical devices 104 will send instructions to ejector device 103, and catapult-launching gear 103 will stretch out at reasonable time in this case.
Like this, the free-falling path of the object 110 falling by the end along from conveyer 105 is arranged a pair of two-way ejector device 102,103 of cascade, and the prior art three tunnel categorizing systems realize Liao San road classification capacity.
Referring now to embodiments of the invention, Fig. 2 illustrates for minute type objects 210 tri-tunnel categorizing systems 201, and it comprises conveyer 205, Optical devices 204, single No. three ejector devices 212 and three separate paths 207,208 and 209.As the situation of the system of Fig. 1, object 210 to be sorted is along conveyer 205 carrieds and can drop from the end of conveyer 205, and its freedom of entry falls herein.As mentioned above, can estimate the free-falling path 206 of object.Path 207,208 and 209 is arranged in conveyer below, and undeflected free-falling object will be along path 209 be advanced, and the deflection of free-falling object 207 or 208 is advanced by the degree being deflected according to it and along path.
Optical devices 204 are located and construct in the similar mode of Optical devices 104 with system 101 along the track 206 of estimating, make the object of free-falling by first passing the visual field 211 of Optical devices 204, this its, can be scanned.Whether the object can real-time judge being scanned should be classified in path 207,208 or 209, and can then dependent instruction be passed to No. three ejector devices 212, with the object of guaranteeing to be scanned, is classified in definite path.During No. three ejector devices 212 can remain on retrieving position or reach two different extended positions---" centre " extended position and " completely " extended position---one.No. three ejector devices 212 guarantee that the object being scanned is correspondingly classified, referring below to Fig. 3,4,5 and 6 explanations in more detail.
No. three ejector devices 212, along track 206 location of estimating, make it along track, be positioned to far away than Optical devices 204.Device 212 is located so that, when device 212 is during in retrieving position, the object of free-falling will pass through device 212 along undeflected track.In addition, device 212 is located so that the object of free-falling will be deflected and leave its normal trace when device 212 is during in " centre " or " completely " extended position.While reaching " centre " position at reasonable time in the free-falling process at object, No. three ejector devices 212 will make the trajectory deflection of object, and it 208 is advanced along path.While reaching " completely " position at reasonable time in the free-falling process at object, No. three ejector devices 212 will make the trajectory deflection of object, and it 207 is advanced along path.Determine that object will 208 or 207 instructions from Optical devices 204 that are classified will make ejector device at reasonable time, reach respectively " centre " and " completely " position along path, to guarantee that object is by 208 or 207 advancing along path like that by appointment.If Optical devices determine object and will be along path 209 advance, this will make catapult-launching gear 212 keep regaining.
Fig. 3 illustrates ejector device 301 according to an embodiment of the invention.Ejector device 301 comprises oar mounting portion 304, deflection oar 302, three position pneumatic linear actuators 303 and main body (not shown).Deflection oar 302 is attached to oar mounting portion 304 pivotly along one end thereof.Oar mounting portion 304 keeps static by main body (not shown), makes the deflection oar 302 can be around its pivotal point 311 with respect to oar mounting portion 304 and main body pivotable.Oar mounting portion 304 can be attached to the main body of ejector device or can be the integral part of this main body.
Three position pneumatic linear actuators 303 comprise cylinder shell 317, front end 316 and rear end 315.Cylinder shell 317 is mounted to the main body of ejector device 301.Pneumatic linear actuator also comprises the back cavity 305 adjacent with rear end 316 and the ante-chamber 308 adjacent with front end 316, by the partition wall 313 in cylinder 303, forms independently chamber 305,308.
The ante-chamber 308 of three position cylinders 303 holds first piston 309, and the first end of secondary piston bar 310 extends from this first piston.The second end of secondary piston bar 310 extends through the hole in cylinder shell 317 and is connected to rotationally deflection oar 302 at tie point 312 places.Secondary piston 310 is towards motion thereby 302 motions away from cylinder end 316 of realization slurry of cylinder end 316.Secondary piston 309 is positioned at ante-chamber 308, makes it limit the first ante-chamber section 318 and the second ante-chamber section 314.The first ante-chamber section 318 is connected to by the air pressure source of the first valve (not shown) operation.In the second ante-chamber section 314, keep constant return force, with by secondary piston 309 against on partition wall 313.This return force applies by being connected to the constant air pressure of the second ante-chamber section 314.When the first valve is when in an open position, the air pressure that is supplied to the second ante-chamber section 314 is less than 318 the air pressure being applied to silently.When secondary piston 309 is during near partition wall 313, secondary piston 309 is in complete retracted state.
The back cavity 305 of three position cylinders 303 holds back piston 306 and back piston bar 307 devices.The stroke ratio of back cavity 305 and back piston 306 is to ante-chamber 308 and short to the stroke of secondary piston 309.Partition wall 313 comprises hole, and back piston bar 307 can extend through this hole.By the hole in partition wall 313, provide gas-tight seal around back piston bar 307.Back piston 306 is positioned at back cavity 305, makes it limit the first back cavity section 319 and the second back cavity section 320.The first back cavity section 319 is connected to the air pressure source operating by second valve (not shown).
By control silently 314 and 318 in pressure, can make secondary piston 309 retracted state, centre are stretched out state and completely stretch out between state and move completely.When being positioned to be resisted against on antetheca 316, secondary piston 309 is in stretching out state completely.When being positioned to be resisted against on partition wall 313, back piston is in stretching out state completely.Should be understood that when back piston stretches out completely, the free end of back piston bar 307 reaches in the first ante-chamber section 318.The length of back piston bar 307 makes when back piston 306 is when stretching out state completely, and back piston bar 307 can act on secondary piston 309, has pushed it to the front end of cylinder 316 and the intermediate point between partition wall 313.In this case, secondary piston 309 base portions are completely regained also and are not exclusively stretched out, but stretch out state in " centre ".When the first valve prevents that air pressure is applied to the first ante-chamber section 318, the return force of the constant air pressure in the second ante-chamber section 318 buffering opposing secondary piston 309 further moves to it and stretches out state completely.
As shown in Figure 3, ejector device 301 is in retrieving position.Second valve is operated to avoid air pressure to be applied to the first back cavity section 319, and air there is discharged from cylinder 303.The first valve is operated to avoid air pressure to be applied to the first ante-chamber section 318, and the Bas Discharged cylinder 303 there.Return force in the second ante-chamber section 314 is shifted secondary piston 309 and back piston 306 onto its retracted state.As a result, secondary piston bar 310 makes oar 302 move to complete retracted state.Like this, ejector device 301 is in complete retracted state.The ejector device of regaining completely that is positioned at the road of San shown in Fig. 2 categorizing system 209 freely falls permission object 110 from conveyer along path, and is not subject to the impact of oar.
As shown in Figure 4, ejector device 301 extended position that mediates.Second valve is operated air pressure to be applied to the first back cavity section 319, makes back piston 306 move to its extended position.The first valve is operated to prevent, and air pressure is applied to the first ante-chamber section 318, and the Bas Discharged firm 303 there.Return force in the second ante-chamber section 314 promotes secondary piston 309 towards partition wall 313, until it is resisted against on back piston bar 307.The power that is applied to the first back cavity section 319 by air pressure is greater than the return force in the second ante-chamber section 314.Therefore, back piston 306 remains on it and stretches out state completely, and therefore secondary piston 309 remains on middle extension state.As a result, secondary piston bar 310 makes oar 302 move to the middle state that stretches out.Like this, ejector device 301 extended position that mediates.When being positioned at that the ejector device 301 of San road categorizing system mediates extended position as shown in Figure 2, the object 110 dropping from conveyer 205 will roll down or slide oar 302 and along path 208.In a preferred embodiment of the invention, middle extended position is the default location of ejector device.
As shown in Figure 5, ejector device 301 is in complete extended position.The first valve is operated air pressure to be applied to the first ante-chamber section 318.The power that is applied to the first ante-chamber section 318 by air pressure is greater than the return force in the second ante-chamber section 314.Therefore secondary piston 309 moves to it and stretches out state.As a result, secondary piston bar 310 makes oar 302 move to the state that stretches out completely.Like this, ejector device 301 is in complete extended position.In the categorizing system shown in Fig. 2, if ejector device now moves to complete extended position, the object 110 sliding from the surface of the deflection oar 302 of the extended position that mediates will be along path 207 be dished out.
It should be noted that in Fig. 5, second valve is operated to prevent, and air pressure is applied to the first back cavity section 319, and back piston 306 does not stretch out state at it.When secondary piston 309 is when it stretches out state completely, this position to ejector device 301 does not have substantial effect.
