Technical field
The present invention relates to automatic classification methods and system, are especially, but not exclusively related to the automatic classification of fruits and vegetables.
The field of the invention also extends into but is not limited to use in the method and system used in rubbish separation, classification and recycling, with
And the method and system used in the separation and classification of the solid granular raw material of such as ore.
Background technique
It is certain for fruits and vegetables based in optical automatic classification system, product to be sorted is from horizontal transmission
The end of band is discharged.Product to be sorted on a moving belt when and/or be scanned optically when flying out from conveyor belt ends, and
Receiving/discarding is made based on the scanning to determine.If fruit product is to be discarded, then its normal flight track is caused a deviation from, and
It deflects into and abandons in slideway.If fruit product will be received, then it enters receiving cunning along its undisturbed normal flight track
Road.This is the feature of basic two-way batch operation.
In practice, it is often necessary to more complicated sort operations.Product may must be broken into more than two classes, such as " etc.
Grade A ", " grade B " and " waste product ", or alternatively " receiving ", " re-working " and " waste product ".Originally these more complex points
Generic operation is realized and making one in two product streams that the first two-way is classified to pass through second sorter.This is needed
Want two different categorizing system (two light scanners, two judgement electronic devices, two ejector devices, two sets of transmission
System etc.).In addition to product by the relevant cost of complete sort operation twice other than, this is also resulted in product excessive wear
Disadvantage.
It is shown in Fig. 1 in the prior art, single ejector device 101 be used for by make two ejector devices 102,
103 (or two rows of this ejector devices) one cascades realize the classification of three tunnels after the other.It is swept using single optics
Device and judgment means 104 are retouched to carry out the classification judgement of three tunnels.When product 110 is by the first ejector device 102, carry out first
Classification, wherein being divided into the first kind, the product of --- such as " waste product " --- is deflected downwards to dedicated path 107, remaining product
Continue to the second ejector device 103.When product 110 is by the second ejector device, the second subseries is carried out, wherein
The product for being divided into the second class (such as " grade B ") is deflected by the second dedicated path 108, and third class (such as " grade
A ") product do not deflect and proceeds to third path 109.
Two complete sorters are not needed, doubles are only ejector devices.However, this arrangement still has one
A little disadvantages.Product must be allowed for fall through compared with big height so that it successively passes through two ejector devices.Which increase damages
A possibility that bad product.Moreover, product has fallen relatively at a distance when product reaches the second ejector device, so that its
The control of exact position and anticipation property are all more inaccurate.Due to increasing " missing classification ", (i.e. such product, the product is
It is selected as deflecting, is but actually missed by ejector device since product reaches the mistake timing of ejector device)
Quantity and the accuracy for reducing the second sort operation.This is due also to increase " unexpected classification " (i.e. such product, product
It is not selected for deflecting, truly has and reach the mistake timing of ejector device with product and actually deflected by ejector device)
Quantity and reduce the accuracy of the second sort operation.In addition to these problems, although the cost of this device, which is lower than, has two
The equipment of a complete sorter, but still have that there are two the relevant costs of complete ejector device to tool.Moreover, the arrangement is multiple
It is miscellaneous and be therefore easy to that there was a mechanical failure.
United States Patent (USP) 7041926 is related to the method for the stone for separating gravel aggregate by one or more predetermined characteristics
And system.This is achieved in the following ways, that is, so that gravel aggregate is extended through the drop pipe by multiple crosspoints, often
A crosspoint is connected to three outlets: the extendible portion of the first distribution flexible pipe, the second distribution flexible pipe and drop pipe.It is a pair of independent
Hinged deflector means are located at each intersection, and each pair of deflector means can cooperating it is hinged, to make
The only one intersected in three outlets pointed out will be opened in any given time.Although the arrangement can be in single location
Complicated classification is carried out, but still must endure as the cost and mechanical complexity of two ejector devices.Moreover, in addition to whole system
Except complexity, the coordination of the movement for the deflector means which also requires two independences hinged.
Therefore, it is necessary to improved multi-class automatic classification method and systems.

As described above, Fig. 1 shows the three tunnel categorizing systems 101 according to prior art systems.For being somebody's turn to do for object 110 of classifying
System include conveyer 105, Optical devices 104, a pair of of two-way ejector device 102,103 and three individual paths 107,
108 and 109.Object 110 to be sorted is along 105 carried of conveyer and can fall from the end of conveyer 105, herein
Locate its freedom of entry whereabouts.Since the quality of all given objects to be sorted usually follows known distribution, and due to passing
It send device to operate at a predetermined velocity, therefore can estimate the track 106 fallen behind under object freedom of entry.Path 107,108 and 109 cloth
It sets below conveyer, so that undeflected free-falling object will advance along path 109, and the deflection of free-falling object
It will be advanced according to its deflected degree along path 107 or 108.
Optical devices 104 with the visual field 111 are positioned along the track 106 of estimation, so that the object of free-falling will be first
Initially pass through the visual field 111.Optical devices 104 can scan across the object in the visual field 111, and the scanned object of real-time judge is
It is no to be classified into path 107,108 or 109.Dependent instruction then can be transferred to ejector device by Optical devices 104
102,103, to ensure that scanned object is classified into determining path.Ejector device 102,103 ensures scanned
Object is correspondingly classified, as described below.
Further along the track 106 (that is, after Optical devices) of estimation, the positioning of the first two-way ejector device 102

Advance in 109 direction.When during object fall in due course between stretch out when, ejector device 102 will make the track of object
Deflection makes it advance along path 107.From Optical devices 104, earnest body will will make along the instruction that path 107 is classified really
Ejector device is obtained to stretch out in reasonable time to ensure that object will advance along path 107.If Optical devices determine object
To advance along path 108 or 109, then this will make ejector device keep withdrawing.Formally due to the path of object free-falling
It is estimated that therefore can also estimate in given point in time object along the position of its estimated path.In this way, can estimate first pair
When road ejector device should stretch out, to ensure that object is deflected along path 107.
Further (that is, after Optical devices and the first ejector device) second pair is located along estimated path 106
Road ejector device 103.Only have already been through the first ejector device and it is non deflected (that is, still along the direction in path 109 before
Into and do not deflected along path 107) the track of object could be deflected by the second ejector device.When the second ejector fills
When setting in retrieving position, it will be passed through and with its undeflected track along path by the deflectable object of device 103
109 advance.When, when reasonable time stretches out, ejector device 103 will make the rail of object in the dropping process in this object
Mark deflection, makes it advance along path 108.Such as the case where the first ejector device 102, if free-falling object will edge
Path 108 deflect, then Optical devices 104 will send instruction, in this case catapult-launching gear 103 to ejector device 103
It will be stretched out in reasonable time.
