Technical field
The present invention relates to the rationed technical field of discrete type article is and in particular to a kind of distribution side of discrete type article
Method, rationed method and its distributor.
Background technology
Device to the quantitative counting of discrete articles among existing industry, it is common to use method has mechanical several
Machine, the counting grain machine of photo-electric, and counting grain machine of view-based access control model technology etc..
Mechanical counting grain machine just can hold a thing using a rotating disk with fixed qty recess, each recess central
Product, by rotating, shaking and scrape equality method, the article just filling up recess taken out of by rotating disk, then disengage packaging.This method is relatively
Simple and cheap, but production capacity is low, as filling out discontented article once in a while and causing error, and when blowing unnecessary article off to thing
Product damage.
Photo-electric counting grain machine uses multichannel mode, using one group of multi-orbit shake disk, article is fed forward, simultaneously
By the vibrations of multilayer, the distance between article are progressively pulled open, last article are arranged into a plurality of single queue and article
Be opened certain distance and article between, to shake disk end in the way of freely falling body under fall, article under fall when triggering correspond to
The photoelectric sensor of its affiliated passage counts, and collects afterwards in container.It is designed with one below the photoelectric sensor of every passage

Send out, the conveying mechanism of article becomes very huge, is that the arrangement of production environment brings a lot of inconvenience.In addition, photoelectric sensor due to
Easily to be polluted by the dust that article are taken out of, to cause counting error near article channels operation.
Several methods of view-based access control model technology use the mode that whole heap counts it is not necessary to separately only need to be article article
Being paved into individual layer makes each article can be obtained image, and by the image obtained by real-time analysis to article counting.In
State's patent of invention, number of patent application discloses a kind of distribution method of article and device, the method for " 201210509818.7 "
Mode using continuous capture counts to the article falling, and first distributes close and no more than target number article, so
Using a feed supplement mechanism, the number distributing first is supplied with the number that differs of target number afterwards, be finally reached target number
Rationed.In order to reach the purpose of accurate feed supplement, feed supplement mechanism must want can individually control exported article
Quantity, operating efficiency is relatively low, but, when conveyer stops, the number of articles continuing due to inertia reason to export is not
Controlled, on the premise of the quantity that will ensure to export first is not more than destination number, the number exporting first just needs and mesh
Mark number keeps a larger gap, then the time needed for feed supplement is also just more, causes one of overall throughput to limit.
Chinese invention patent of invention, number of patent application 201410109547.5 discloses a kind of article quantitatively point heap and counting
Method and device, belong to several methods of view-based access control model technology, periodically rise by a plurality of article passage and conveyer
Dynamic and stop, article are divided into multiple stack of articles outputs, and the continuous capture analyze gained image to the stack of articles falling
In the article number to draw stack of articles for the article image, and each stack of articles is stored among a temporary storing bin, to different
Article number in temporary storing bin is combined computing, finds the combination that summation is target number, and it is disengaged to obtain
The distribution of target number.This method breach in above-mentioned method of making up the difference due to feed supplement mechanism efficiency and first sendout with
The factors such as machine are to the impact caused by production capacity.But, due to the restriction of machinery and physical space, the number of temporary storing bin is limited
, then, just have an opportunity to can not find the situation of combination, and need the two heap article to be superimposed in same temporary storing bin and
The situation that temporary storing bin quantity is overflowed, this all can impact to production capacity.
Several methods of two kinds of above view-based access control model technology are all by conveyer being started and stopping coming article stream
Disjunction, thus reach effect article being divided heap.Make up the difference in method, each starting of conveyer and stopping, just corresponding to a pile
The article distribution of target number；And in combined method, conveyer starts every time and stops, just separating multiple stack of articles, then lead to
Cross combination articles heap and draw the article distribution of target number.So, no matter which method, the overall production capacity of system is all subject to
Actual the starting of conveyer and the cycle of stopping can be operated to be limited, and in practical operation, used due to conveyer itself
Measure the restriction to starting and the reaction stopping, and when conveyer stops, waiting article to stop the time delay needed for output completely, all account for
With relatively many cycle time, so that the startup of conveyer and dwelling period all become the bottle of system production capacity under many circumstances
Neck.

Find the combination of at least one stack of articles in the stack of articles that contained article number has been learnt on face, and output it.
The present invention divides heap and counting in conveyor surface article, and extracts suitable stack of articles combination, in article simultaneously
Heap is just sent directly into container when conveyer exports, and central does not require the use of temporary storing bin.
Temporary storing bin is in one group of mechanism between conveyer and container, in order to reach temporary article and the mesh disengaging article
, each temporary storing bin has to be provided with the gate that can switch with independent control, in practical situations both due to physical space and transmission
The restriction in path, temporary storing bin is more, frame for movement will huger and drive path also more complicated, so the number of temporary storing bin is just
Limit, but will cause if setting temporary storing bin very little to can not find appropriate combination and quantity increases situations such as spilling.And
Due to not needing to use temporary storing bin, article just can be directly entered container after leaving conveyer to the present invention, road through greatly shortening,
Also save space, and simplify mechanism.
In described step one, article are divided into by stack of articles by the form that the feed surface in conveyer arranges lattice,
Described article enter in lattice, and article are formed a stack of articles by each lattice, and the stack of articles of different lattices is not mutually reported to the leadship after accomplishing a task.
Article divide heap in conveyor surface, can be realized by arranging lattice in feed surface, article fall in conveyer
When just naturally fall into lattice, be just counted afterwards, and by being to have been limited by lattice when stack of articles is counted, different points
The stack of articles of lattice is not mutually reported to the leadship after accomplishing a task, thus it is guaranteed that until when exporting, the article number being drawn is in conveyer course of conveying
The most real, it is just to be kept in after counting with respect to article in prior art, just it may happen that article road after counting in the middle of that
Malfunction and make real temporary article number and count situation about not being inconsistent in footpath, the present invention significantly provides more superior reliability.
Meanwhile, article naturally fall into lattice, and reach an accurate number using the method for the different stack of articles of combination, thing
The stool and urine of product heap can be random, fall into the article number of lattice without precise control, and then conveyer also just can connect
Move, the supply of article also just can be continuous continuously.Lattice is distributed in row and column fashion, makes each stack of articles defeated
Send the time of device output and position can be determined in advance, the stack of articles in same stack of articles combination is just permissible in output
Easily collected.With respect in prior art by conveyer periodically being started and stopping realizing article to divide
Heap, and overall throughput is just limited in startup and the cycle restriction itself stopping, the present invention clearly can make article stream more smoothly
And bigger production capacity room for promotion is provided.
Stack of articles is arranged in feed surface in terms of rows and columns, and row's stack of articles of the horizontal arrangement of conveyer is one
Row, row's stack of articles of the conveying direction arrangement of conveyer is a line, and stack of articles is in the form of arranging more than one and/or being more than a line
Feed surface distribution in conveyer.The present invention allows that the mode scanning including line and two kinds of forms of taking pictures realize the number of article
Calculate.
Described pave as individual layer, can be by adding the form such as vibrating mechanism or scraper plate to realize in conveyer, article

Compare assess article number using the mode weighed and with known article average weight, then carry out group than in prior art
Close computing, the present invention can obtain the stack of articles combination of accurate number, and allocative efficiency is high.
Embodiment 2
A kind of rationed method of discrete type article, including
Step one, to conveyer article without interruption, article are paved as individual layer and are divided in the feed surface of conveyer
It is divided into stack of articles, stack of articles is to the output end conveying of conveyer；
Step 2, the number to the article that each stack of articles is comprised count, and obtain the article in each stack of articles
Number；
Step 3, learn on the transport surface in the stack of articles of contained article number and found at least one stack of articles group
Close；The summation of article number of the comprised stack of articles of described stack of articles combination is identical with target item number；To belong to same
The stack of articles of individual stack of articles combination is labeled as belonging to the combination of this stack of articles, and each the stack of articles group searching out is combined in conveying
During device output, using the one stack of articles combination of a container reception；Any one stack of articles is when leaving the output end of conveyer
Not yet during selected to one stack of articles combination, reject this stack of articles in output.
The present invention be article are made rationed, can be more effectively and more simply and easily with the stack of articles group of feed surface
The output to realize the article of different numbers for the mode closed, and it is more to work as the stack of articles number being available for choosing on feed surface, when
In the chance that is capable of exporting article according to a desired value also just higher.In the method, stack of articles is on a conveyor
It is continuous flowing, new article can constantly fall in conveyor surface and form stack of articles, also constantly exported, are also
Say, can although with selected stack of articles number be limited, but be available for the numerical value of the article number used by combinatorial operation
It is continually changing, suitable combination just also can constantly occur, and carrys out storing products with respect in prior art using temporary storing bin
Heap, when will new individual numerical value to make combinatorial operation, just needs to put into new article to temporary storing bin, and central part has carried
The temporary storing bin having article will occur quantity to be superimposed, and (i.e. the article number in a temporary storing bin is big finally to occur quantity to overflow
In target number) situation.This method clearly avoids and asking of quantity spilling occurs when making rationed in prior art
Topic.
Certainly, disallowable (disallowable stack of articles can be cycled back in output not to have selected stack of articles
Loader use), be a discount to production capacity, but as long as make to need disallowable stack of articles ratio sufficiently small, in conjunction with
Upper described usefulness in terms of production capacity, is that the present invention just can provide more superior comprehensive production capacity.And it is obvious that in quantitation
On the premise of distribution, must have some in the stack of articles of conveyor surface is to be used in selected stack of articles combination
In, but the ratio lowering the stack of articles needing to reject can be reached by following arrangement：
Receive stack of articles using more containers simultaneously.Following example illustrates the impact of this factor：
Figure one shows the stack of articles having single file to arrange on a conveyer, and during output, the same time is only by a container
Receive, so next stack of articles combination just must can be exported after a stack of articles combination exports completely, according to 50 mesh
Mark number distribution, occurs in that 4 need disallowable stack of articles.
Figure two shows the stack of articles of same a line, but output when the same time can be received by most two containers, do not have
Stack of articles is had to need disallowable.
Using less stack of articles.Following example illustrates the impact of this factor：
Figure three shows the stack of articles having 4 row on a conveyer, and the article number of each stack of articles is random between 5～12
Change, during output the same time by can be received by two containers, according to 50 target number distribution, the 17 of output first
4 stack of articles are had to need in row stack of articles disallowable.
Figure four shows 4 same row stack of articles, and most two containers receive simultaneously, and divide according to 50 target number
Join, but the size reduction of stack of articles be change at random between 1～9, do not need in 17 row stack of articles of output first by
The stack of articles rejected.
Allow the stack of articles combination of output is carried out making up the difference reaching target number.Following example illustrates this factor
Impact：
Figure five shows the size distribution of same with figure three stack of articles, equally can be by most two with the same time
Individual container receiving stack of articles and using 50 as target number, due to can allow to make up the difference, the article of each stack of articles combination
As long as number be no more than 50 just can, do not need disallowable stack of articles in 17 row stack of articles of output first.
In described step 3, when the new stack of articles being counted in feed surface, new add be counted
Stack of articles and the/original stack of articles being counted of former feed surface in find combination, being counted of described former feed surface

Wherein, in described step 3, when finding the combination of product heap, the priority leaving the output end of conveyer with stack of articles is suitable
Sequence enters row operation, preferentially formerly leaves in the stack of articles of conveyer output end and finds.
Wherein, in described step 2, described be counted as by stack of articles capture, and obtained image is carried out point
Analysis is to obtain the article number in stack of articles.
Wherein, described target item number is the individual numerical value of numerical value or a scope one by one.
Embodiment 3
Embodiment 3 is with the difference of embodiment 2：The present embodiment is proposed and is allocated by the form made up the difference, described
In step 3, do not have in labeled stack of articles that to there is not an article number identical with target item number when feed surface
Stack of articles combination when, find out comprised an article number be less than target item number stack of articles combine, calculate this thing
The contained article number of product heap combination differs number with target number；And supply difference to the container receiving the combination of this stack of articles
Number.
In described step 3, by the feed supplement mechanism of the article that can accurately export any number, to described appearance
The article of distribution described difference number in device.
Reach the rationed of article using to the method made up the difference of stack of articles combination of output, above explanation it
In can greatly reduce the needs of rejection of commodities heap hence it is evident that finding out and allowing to make up the difference, it is relative for allowing to make up the difference with rejection of commodities heap
, allow more to stack of articles combination number of making up the difference, need the chance of rejection of commodities heap just less, vice versa.So, one
Determine the permissible of degree to make up the difference in number, be possible to be completely eliminated the needs to rejection of commodities heap.Make up the difference is to need
Want the working time, in ideal conditions, number of making up the difference should be the smaller the better, so for feed supplement mechanism duty requirements just
Can be relatively low, and in actual applications, to lower the needs of rejection of commodities heap by using above-mentioned carried different arrangement, and
Allow a number of making up the difference that reasonably can be easily reached by prior art, just can accomplish rejection of commodities heap is completely eliminated
Need.And with respect in prior art, Chinese invention patent, a kind of article disclosed in number of patent application " 201210509818.7 "
Distribution method and device, similarly reach target number using the mode made up the difference, the present invention significantly provides following technology
Advantage：
In the present invention, distribution number also can be not in the situation that quantity is overflowed closer to target number simultaneously first.
In prior art, differing of distribution number and target number has been to deposit random first, needs guarantee not to be more than target number, just
Need to accept larger number of making up the difference.Although the article number of stack of articles is random in the present invention, but after combination,
Randomness between stack of articles and stack of articles is just cancelled out each other, finally just can draw one can be controllably closer to target
The combination of number.Following example illustrates this point：It is assumed that the number of stack of articles is change between 5～15, then stack of articles combines
Article number and the difference of target number just should not be more than 15 and (if an article number combining is more than 15, just should
Can take a stack of articles more and make result closer to and be not more than target number), and this difference number just should be averagely big
The centre (i.e. 10) of the general excursion in stack of articles.But, due to can select consciously when extracting combination, and
Alternative combination enough number of when, this phase difference just should be averagely in a lower scope.And it is true
Above it is easy to as can be seen that in the method, because the selection of combination is conscious, can obtain and mesh when extracting combination
Mark number identical chance is presence significantly, and the situation that quantity is overflowed simultaneously also will not occur.On the contrary, in prior art
In, being fundamentally to allow that sendout first just draws the situation of target number, because of this situation once occurring, just meaning to count
The situation that amount is overflowed also must occur.
In the present invention, sendout is output and has learnt before distributing article are actual first, and feed supplement mechanism just has
Sufficiently the time prepares, and in fact, when there are multiple selected stack of articles combination on a conveyor, feeding machine
Structure just can close the little number stack of articles group that the saved time makes up the difference of making up the difference used in many numbers, makes the work of feed supplement mechanism
More efficiently.On the contrary, in the prior art, number of making up the difference is just to draw after the stack of articles output distributing first, feeding machine
Structure needs the short time to react and completes output of making up the difference, to avoid affecting next cycle.Meanwhile, making up the difference the time in different cycles
Also cannot be complementary, even if be also in once little number is made up the difference feed supplement mechanism fulfil output of making up the difference ahead of schedule, saved when
Between be also not used in the making up the difference in work of another cycle.So, the speed of feed supplement mechanism just needs by maximum number of making up the difference
To realize, the machinery to feed supplement mechanism and controlling requires high, and or feed supplement mechanism may become the bottleneck of overall throughput.
As it was previously stated, the supply of article is continuous in the present invention, with respect to the stack of articles distributed first in prior art
By starting and stopping conveyer realizing, the present invention provides more excellent production capacity and more smooth running.
