The distribution method of discrete type article, distribution method of making up the difference and distributor
Technical field
The present invention relates to the rationed technical field of discrete type article, and in particular to a kind of distribution side of discrete type article
Method, make up the difference rationed method and its distributor.
Background technology
To the device of the quantitative counting of discrete articles among existing industry, it is common to use method has mechanical several
Counting grain machine of machine, the counting grain machine of photo-electric, and view-based access control model technology etc..
Mechanical counting grain machine can just hold a thing using a rotating disk with fixed qty recess, central each recess
Product, by rotating, shaking and scrape equality method, rotating disk takes the article for just filling up recess out of, then disengages packaging.This method compared with
It is simple and cheap, but production capacity is low, as fill out discontented article once in a while and cause error, and when unnecessary article is blown off to thing
Product are damaged.
Photo-electric counting grain machine is fed forward article using the shake disk of one group of multi-track using the mode of multichannel, while
By the vibrations of multilayer, the distance between article is progressively pulled open, last article is arranged into a plurality of single queue and article
Certain distance is opened between article, is fallen under shaking disk end in the way of freely falling body, correspondence is triggered when article falls under
The photoelectric sensor of its affiliated passage is counted, and is collected into container afterwards.One is designed with below the every photoelectric sensor of passage
Individual self-shooter, closes when destination number is reached, and is used to distinguish every heap article.But, the counting grain machine of multi-channel type due to
Need article to be divided into course of conveying between different single-row passages and article and separate, photoelectric sensor is effectively touched
Hair, the conveying mechanism of article becomes very huge, is that the arrangement of production environment brings many inconvenience.In addition, photoelectric sensor due to
Article channels operation is close to, is easily polluted by the dust that article is taken out of, cause counting error.
The mode that several methods of view-based access control model technology are counted using whole heap, it is not necessary to separately only need to be article article
Being paved into individual layer makes each article to be obtained image, and by the image obtained by analysis in real time to article counting.In
State's patent of invention, number of patent application is the distribution method and device that " 201210509818.7 " disclose a kind of article, the method
The article for falling is counted using the mode of continuous capture, first distribute close to and the no more than article of target number, so
The number for distributing first is supplied with the number that differs of target number using a feed supplement mechanism afterwards, target number is finally reached
It is rationed.In order to reach the purpose of accurate feed supplement, feed supplement mechanism must want individually control exported article
Quantity, operating efficiency is relatively low, but, when conveyer stops, the number of articles that output is continued due to inertia reason is not
Controllable, on the premise of the quantity that ensure to export first no more than destination number, the number for 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 and quantitatively divides heap and counting
Method and device, belong to several methods of view-based access control model technology, periodically risen by a plurality of article passage and conveyer
It is dynamic and stop, article is divided into multiple stack of articles outputs, and the continuous capture of stack of articles to falling and analyze gained image
In article image to draw the article number of stack of articles, and each stack of articles is stored among a temporary storing bin, to different
Article number in temporary storing bin is combined computing, and it is a combination of target number to find summation, 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 influence caused by production capacity.But, due to the limitation of machinery and physical space, the number of temporary storing bin is limited
, then, just have an opportunity the situation that can not find combination, and need the two heap articles to be superimposed in same temporary storing bin and
The situation that temporary storing bin quantity is overflowed, this can all be impacted to production capacity.
Several methods of two kinds of view-based access control model technologies above are started and stopped come article stream by conveyer
Disjunction, so as to reach the effect article point heap.In method of making up the difference, each starting and stopping of conveyer just correspond to a pile
The article distribution of target number;And in combined method, conveyer is started and stopped every time, multiple stack of articles are just separated, then lead to
Cross combination articles heap and draw the article of target number and distribute.So, no matter which method, the overall production capacity of system is all subject to
The cycle of starting and the stopping of conveyer can be actually operated to be limited, and in practical operation, due to conveyer being used in itself
The limitation of reaction of the amount to starting and stopping, and wait article to stop the time delay needed for exporting completely during conveyer stopping, all accounting 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.

Beneficial effects of the present invention are as follows:
The present invention divides heap and counting in conveyor surface article, and chooses suitable stack of articles combination simultaneously, in article
Heap is just sent directly into container when being exported from conveyer, central without the use of temporary storing bin.
Temporary storing bin is one group of mechanism being located between conveyer and container, in order to reach temporary article and disengage the mesh of article
, each temporary storing bin has to be provided with the gate that can be switched with independent control, in practical situations both due to physical space and transmission
The limitation in path, temporary storing bin is more, mechanical structure will huger and drive path it is also more complicated, so the number of temporary storing bin is just
It has been limited that, but to set cause if temporary storing bin very little and can not find appropriate combination and increase situations such as quantity is overflowed.And
Due to that need not use temporary storing bin, article just can be directly entered container to the present invention after conveyer is left, road through greatly shortening,
Space is not only saved, and also simplify mechanism.
Article can realize that article falls in the feed surface point heap of conveyer by setting lattice in feed surface
Just lattice is naturally fallen into during conveyer, is just counted afterwards, and by being to be limited by lattice when stack of articles is counted,
The stack of articles of different lattices is not reported to the leadship after accomplishing a task mutually, thus it is guaranteed that in conveyer course of conveying when output, the article for being drawn
Number is most real, is just to be kept in after counting relative to article in the prior art, after just may being counted in the middle of that
Article path is malfunctioned and makes real temporary article number and count situation about not being inconsistent, the present invention significantly provide it is more superior can
By property.Meanwhile, article naturally falls into lattice, and reaches an accurate thing using the method for combining different stack of articles
Product number, the stool and urine of stack of articles can be random, and the article number of lattice is fallen into without precise control, and then conveyer is just
Can continuously move, the supply of article also just can be continuous.Lattice is distributed in row and column fashion, makes each article
The time and position for piling up conveyer output can be determined in advance, and the stack of articles in same stack of articles combination is in output
Just can easily be collected.Relative to realizing handle by conveyer periodically being started and being stopped in the prior art
Article point heap, and overall throughput is just limited in the cycle limitation of startup and stopping in itself, the present invention can clearly make article stream
More smoothly and provide bigger production capacity room for promotion.
It is an object of the present invention to export an article for accurate number, each stack of articles is to take in the present invention
The method of picture is by accurate metering, and the article number of each stack of articles combination being selected in conveyor surface is its contents
The summation of the article number of product heap, so the number of the stack of articles combination for being exported is also accurate.In the thing of conveyor surface
Product heap is more, and the probable value of the article number that can be drawn by combination articles heap is just more, then conveyer can meet
The applicability for exporting article the need for different output numbers is just stronger.The number of the stack of articles of conveyor surface can be logical
The number of the lattice for increasing conveyor surface is crossed to reach, and this is also easily to pass through some simple configuration changes just
It is capable of achieving, this includes reducing the size of each lattice, lengthens or widen conveyer etc..Relative in the prior art using temporary storing bin
Method, it is necessary to just need correspondingly to add new gate and transmission mechanism, convenience of the invention when increasing the number of temporary storing bin
Property and flexibility are fairly obvious.
Another usefulness of the invention can be that profile while being allowed in counting to article is detected, due to
Article is laid in feed surface by capture, and under the support of transporting flat, and the direction of article is stable, is also thing
The shape size of the image of product should be also fixed, while so just allowing that capture is counted, to each article image with it is pre-
If image and parameter compare, the article damaged to find out profile.In the article for finding to have profile damaged, as long as not
Stack of articles belonging to it is used as selection combination to be used, the stack of articles will be by automatic rejection in output.Relative to existing skill
In art, article is that, by capture in the state of freely falling body, the direction that article is not fixed, SHAPE DETECTION just can not possibly be entered
OK.

Specific embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Embodiment one
A kind of distribution method of discrete type article, including step one, to conveyer article without interruption, article is in conveyer
Feed surface paved as individual layer and be separated into stack of articles, output end from stack of articles to conveyer convey;Step 2, to every
The number of the article that individual stack of articles is included is counted, and obtains the article number in each stack of articles;Step 3, conveying table
The combination of at least one stack of articles is found in the stack of articles that contained article number has been learnt on face, and is output it.
The present invention divides heap and counting in conveyor surface article, and extracts suitable stack of articles combination simultaneously, in article
Heap is just sent directly into container when being exported from conveyer, central without the use of temporary storing bin.
Temporary storing bin is one group of mechanism being located between conveyer and container, in order to reach temporary article and disengage the mesh of article
, each temporary storing bin has to be provided with the gate that can be switched with independent control, in practical situations both due to physical space and transmission
The limitation in path, temporary storing bin is more, mechanical structure will huger and drive path it is also more complicated, so the number of temporary storing bin is just
It has been limited that, but to set cause if temporary storing bin very little and can not find appropriate combination and increase situations such as quantity is overflowed.And
Due to that need not use temporary storing bin, article just can be directly entered container to the present invention after conveyer is left, road through greatly shortening,
Space is also saved, and simplifies mechanism.
In the step one, article is divided into by stack of articles by the form that lattice is set in the feed surface of conveyer,
The article enters in lattice, and article is formed a stack of articles by each lattice, and the stack of articles of different lattices is not reported to the leadship after accomplishing a task mutually.
Article can realize that article falls in conveyer in conveyor surface point heap by setting lattice in feed surface
When just naturally fall into lattice, be just counted afterwards, and by being to be limited by lattice when stack of articles is counted, difference point
The stack of articles of lattice is not reported to the leadship after accomplishing a task mutually, thus it is guaranteed that until when exporting, the article number for being drawn is in conveyer course of conveying
It is most real, it is just to be kept in after counting relative to article in the prior art, article road after just may being counted in the middle of that
The situation that footpath is malfunctioned and makes real temporary article number not be inconsistent with counting, the present invention significantly provides more superior reliability.
Meanwhile, article naturally falls into lattice, and reaches an accurate number using the method for combining different stack of articles, thing
The stool and urine of product heap can be random, and the article number of lattice is fallen into without precise control, and then conveyer also just can be even
Move continuously, the supply of article also just can be continuous.Lattice is distributed in row and column fashion, makes each stack of articles defeated
Sending time that device is exported and position can be determined in advance, and the stack of articles in the combination of same stack of articles just can be with output
Easily collected.Relative to being realized article point by conveyer periodically being started and being stopped in the prior art
Heap, and overall throughput is just limited in the cycle limitation of startup and stopping in itself, 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 more than a row and/or more than a line
It is distributed in the feed surface of conveyer.The present invention allows that the mode and two kinds of forms of taking pictures that include line scanning realize the number of article
Calculate.
Described paving is individual layer, by conveyer the forms such as vibrating mechanism or scraper plate can be added to realize, article
Individual layer can be scanned easily by line or the form taken pictures carries out capture to stack of articles, and then can be clearly by analyzing image
The number for knowing article of Chu.

Embodiment 2
A kind of distribution method of the discrete type article based on the mode of making up the difference, including
Step one, to conveyer article without interruption, article is paved as individual layer and divided in the feed surface of conveyer
Stack of articles is divided into, stack of articles is conveyed to the output end of conveyer;
Step 2, the number of the article included to each stack of articles are counted, and obtain the article in each stack of articles
Number;
At least one institute is found in step 3, the stack of articles being counted on the transport surface to be not more than comprising article number
The stack of articles combination of target item number, each stack of articles that will be searched out is combined when conveyer is exported, and uses an appearance
Device receives a stack of articles combination;And it is individual with differing for target item number to calculate the article number of the stack of articles of the combination
Number,
Step 4, by a feed supplement mechanism for the article that can accurately export any number, in the container points
Article with the difference number
It is described to be counted as by stack of articles capture in the step 2, and resulting image is analyzed with
Obtain the article number in stack of articles.
In the step 3, any one stack of articles is not selected to an article yet when the output end of conveyer is left
When heap is combined, the stack of articles is rejected in output.
In the step 3, when feed surface newly adds the stack of articles being counted, the thing that has been counted newly is being added
Product heap and/the original stack of articles being counted of feed surface in find stack of articles combination, the feed surface it is original by
Be free of in the stack of articles of counting and be selected to a stack of articles for stack of articles combination.
In the step 3, when the stack of articles being counted that feed surface is newly added, it has been counted in new addition
Stack of articles and original all being counted in stack of articles of feed surface find stack of articles combination.
In the step 3, when stack of articles combination is found, the sequencing of the output end of conveyer is left with stack of articles
Computing is carried out, searching in the stack of articles of conveyer output end is preferentially formerly left.
The present invention is that article is made rationed, can be more effectively and more simply and easily with the stack of articles group of feed surface
The mode of conjunction realizes the output of the article of different numbers, and works as and be available for the stack of articles number chosen more on feed surface, when
In can realize that the chance that article is exported according to a desired value is also just higher.In the method, stack of articles is on a conveyor
It is constantly flowing, new article can constantly fall in conveyor surface and form stack of articles, also constantly be exported, and be also
Say, although can be limited with the number of selected stack of articles, 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, relative to carrying out storing products using temporary storing bin in the prior art
Making during combinatorial operation, will occur new individual numerical value in heap, just need to put into new article to temporary storing bin, and central part has carried
The temporary storing bin for having article will occur quantity superposition, and quantity spilling finally occurs, and (the article number in i.e. one temporary storing bin is big
In target number) situation.This method is clearly avoided there is asking for quantity spilling when making rationed in the prior art
Topic.
Certainly, to be removed that (stack of articles being removed can be cycled back in output without selected stack of articles
Loader is used), be a discount to production capacity, but as long as making the ratio of the stack of articles that needs are removed sufficiently small, with reference to
The upper usefulness in terms of production capacity, is that the present invention just can provide more superior comprehensive production capacity.And it is obvious that quantitative
On the premise of distribution, it is that can not be used in selected stack of articles combination that must have some in the stack of articles of conveyor surface
In, but the ratio of the stack of articles for needing to reject can be lowered to reach by following arrangement:
Stack of articles is received using more containers simultaneously.Following example illustrates the influence of this factor:
Figure one shows the stack of articles for having single file to arrange on a conveyer, and the same time is only by a container during output
Receive, so next stack of articles combination must can be just exported after a stack of articles combination is exported completely, according to 50 mesh
Mark number distribution, occurs in that 4 stack of articles for needing to be removed.
Figure two shows the stack of articles of same a line, but during output the same time can be received by most two containers, do not have
Having stack of articles needs to be removed.
Use less stack of articles.Following example illustrates the influence of this factor:
Figure three shows the stack of articles for having 4 rows on a conveyer, and the article number of each stack of articles is random between 5~12
Change, the same time, by that can be received by two containers, distributes, in 17 for exporting first according to 50 target number during output
Having 4 stack of articles in row stack of articles needs to be removed.
Figure four shows 4 same row stack of articles, and most two containers are received simultaneously, and according to 50 target number point
Match somebody with somebody, but the size reduction of stack of articles is the change at random between 1~9, do not needed in the 17 row stack of articles for exporting first by
The stack of articles of rejecting.
Allow the stack of articles combination for exporting is made up the difference to reach target number.Following example illustrates this factor
Influence:
Figure five shows the size distribution of stack of articles same with figure three, equally can be by most two with the same time
Individual container receives stack of articles and using 50 as target number, due to that 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, the stack of articles being removed is not needed in the 17 row stack of articles for exporting first.
Combine the method made up the difference to reach the rationed of article using the stack of articles to exporting, the explanation more than it
In, hence it is evident that find out that it is relative to allow to make up the difference with rejection of commodities heap the need for allowing to make up the difference and can greatly reducing rejection of commodities heap
, allow to make up the difference that number is more to stack of articles combination, it is necessary to the chance of rejection of commodities heap is just smaller, vice versa.So, one
Determine the permissible of degree to make up the difference in number, the need for being possible to be completely eliminated 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, by using above-mentioned carried different arrangement to lower rejection of commodities heap the need for, and
Allow a number of making up the difference that can be reasonably easily reached by prior art, just can accomplish that rejection of commodities heap is completely eliminated
Need.And relative in the 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, number is distributed first can be closer to target number, while being also not in the situation that quantity is overflowed.
In the prior art, distribution number has been to deposit random, it is necessary to ensure not to be more than target number, just with differing for target number first
Need to receive larger number of making up the difference.In the present invention, although the article number of stack of articles is random, but pass through after combination,
Randomness between stack of articles and stack of articles is just cancelled out each other, just can finally draw one can controllably closer to target
Several combinations.Following example illustrates this point:It is assumed that the number of stack of articles is changed between 5~15, then stack of articles is combined
Article number and the difference of target number just should not be more than 15 (if an article number for combining just should more than 15
A stack of articles can be taken more and make result closer to without being 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, can be to select consciously due to extracting during combination, and
Alternative combination it is enough number of when, this phase difference just should averagely in a lower scope.And it is true
On, it is easy to as can be seen that in the method, because the selection of combination is conscious, can be obtained and mesh when extracting combination
Mark number identical chance exists significantly, and the situation that quantity is overflowed simultaneously will not also occur.Conversely, in prior art
In, it is fundamentally that can not allow that sendout first just draws the situation of target number, because of this situation once occurring, just mean number
Measuring situation about overflowing must also occur.
In the present invention, sendout is output and learnt before distributing article is actual first, and feed supplement mechanism just has
The sufficient time prepares, and in fact, there are on a conveyor it is multiple be selected stack of articles combination when, feeding machine
Small number just can be made up the difference the saved time with the stack of articles combination made up the difference in many numbers by structure, make the work of feed supplement mechanism
More efficiently.Conversely, in the prior art, number of making up the difference just is drawn after the stack of articles output for distributing first, feeding machine
Structure needs the short time to react and completes output of making up the difference, to avoid influenceing next cycle.Meanwhile, making up the difference the time in different cycles
Also cannot be complementary, even if be also in once small 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 is just needed by maximum number of making up the difference
To realize, machinery and control to feed supplement mechanism require it is 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, relative to the stack of articles distributed first in the prior art
Realized by starting and stopping conveyer, the present invention provides more excellent production capacity and more smooth running.
