Description
Technical field
The present invention relates to the rationed technical fields 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 technique
To the device of the quantitative counting of discrete articles among existing industry, it is common to use method has mechanical several
Machine, counting grain machine and the counting grain machine of view-based access control model technology of photo-electric etc..
Mechanical counting grain machine uses a turntable with fixed quantity recess, and each recess can just hold an object in the middle
Product by rotation, vibration and the methods of strike off, and turntable takes the article for just filling up recess out of, then releases packaging.This method compared with
It is simple and cheap, but production capacity is low, as filling out discontented article once in a while and causing error, and when blowing extra article off to object
Product damage.
Photo-electric counting grain machine uses the mode of multichannel, article is fed forward using the shake disk of one group of multi-track, simultaneously
By the vibration of multilayer, the distance between article is gradually pulled open, last article is arranged into a plurality of single queue and article
It is opened certain distance between article, until falling under shaking disk end in a manner of freely falling body, triggers and corresponds to when article falls under
The photoelectric sensor in its affiliated channel counts, and is collected into container later.One is designed with below the photoelectric sensor in every channel
A self-shooter, the closing when reaching destination number, to distinguish every heap article.But the counting grain machine of multi-channel type due to
It needs article to be divided into during transportation and is separated between different single-row channels and article, touch photoelectric sensor effectively
Hair, the conveying mechanism of article become very huge, bring many inconvenience for the arrangement of production environment.In addition, photoelectric sensor due to
Will be close to article channels operation, the dust for being easy to be taken out of by article pollutes, and causes counting error.
The mode that several methods of view-based access control model technology are counted using whole heap, not needing separately only need to be article article
Being paved into single layer makes each article that can be obtained image, and by analyzing obtained image in real time to article counting.In
State's patent of invention, number of patent application are that " 201210509818.7 " disclose the distribution method and device of a kind of article, this method
The article fallen is counted using the mode of continuous capture, first distributes article that is close and being not more than target number, so
The number distributed for the first time is supplied using a feed supplement mechanism with the number that differs of target number afterwards, is finally reached target number
It is rationed.In order to achieve the purpose that accurate feed supplement, feed supplement mechanism must want individually control exported article
Quantity, working efficiency is lower, and still, when conveyer stops, the number of articles that output is continued due to inertia is not
Controllable, under the premise of the quantity that guarantee to export for the first time is not more than destination number, the number exported for the first time just needs and mesh
It marks number and keeps a biggish gap, then the time needed for feed supplement is also just more, one of overall throughput is caused to limit.
Chinese invention patent of invention, number of patent application 201410109547.5 disclose a kind of article and quantify stacking and counting
Method and device, belong to several methods of view-based access control model technology, periodically risen by a plurality of article channel and conveyer
Article is divided into multiple stack of articles and exported by dynamic and stopping, and to the continuous capture of the stack of articles fallen and analyzes gained image
In article image to obtain 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 operation, finds the combination that summation is target number, and it is released to obtain
The distribution of target number.This method breach in above-mentioned method of making up the difference due to the efficiency of feed supplement mechanism and for the first time sendout with
The factors such as machine are to influence caused by production capacity.But due to mechanical and physical space limitation, the number of temporary storing bin is limited
, then, just have an opportunity there is a situation where can not find combination, and need two heap articles to be superimposed in the same temporary storing bin and
The case where temporary storing bin quantity is overflowed, this can all impact production capacity.
Several methods of the two kinds of above view-based access control model technologies are all by the way that conveyer is started and is stopped come article stream
Disjunction, to achieve the effect that article stacking.In method of making up the difference, each starting and stopping of conveyer just correspond to a pile
The article of target number distributes；And in combined method, conveyer starts and stops every time, just separates multiple stack of articles, then lead to
It crosses combination articles heap and obtains the article of target number and distribute.So, no matter which method, the overall production capacity of system all by
The period that starting and the stopping of conveyer can actually be operated is limited, and in actual operation, due to being used to for conveyer itself
Delay needed for waiting article to stop output completely when stopping to the limitation for the reaction for starting and stopping and conveyer is measured, is all accounted for
With relatively more cycle time, so that the starting of conveyer and dwelling period all become the bottle of system production capacity in many cases
Neck.
Therefore, it is in the prior art there are aiming at the problem that, that it is urgent to provide a kind of allocative efficiencies is higher, it is reliable and manufacture at

Embodiment one
A kind of distribution method of discrete type article, including Step 1: article is in conveyer to conveyer article without interruption
Feed surface paved as single layer and be separated into stack of articles, stack of articles to the output end of conveyer convey；Step 2: to every
The number for the article that a stack of articles is included is counted, and the article number in each stack of articles is obtained；Step 3: in conveying table
It has been learnt on face and has found the combination of at least one stack of articles in the stack of articles of contained article number, and output it.
The present invention, article stacking and counting, and extracts the combination of suitable stack of articles in conveyor surface simultaneously, in article
Heap is just sent directly into container when exporting from conveyer, is without the use of temporary storing bin in the middle.
Temporary storing bin is one group of mechanism between conveyer and container, in order to reach temporary article and release the mesh of article
, each temporary storing bin has to be equipped with the gate that can be switched with independent control, in practical situations 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 is limited, but situations such as can not find appropriate combination and quantity spilling increase will be caused if very little temporary storing bin is set.And
For the present invention due to not needing using temporary storing bin, article can be directly entered container after leaving conveyer, road through greatly shortening,
Space is also saved, and simplifies mechanism.
In the step 1, by the way that article is divided into stack of articles by way of lattice is arranged 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 be realized, article falls in conveyer in conveyor surface stacking by the way that lattice is arranged in feed surface
When just naturally fall into lattice, be just counted later, and by being to have been 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 the article number obtained is when exporting in conveyer transmission process
Most true, middle article is just to be kept in after counting compared with the existing technology, article road after that can be counted in the middle
Diameter malfunctions and makes really to keep in the case where article number is not inconsistent with counting, and the present invention significantly provides more superior reliability.
Meanwhile article naturally falls into lattice, and reach an accurate number using the method for combining different stack of articles, object
The stool and urine of product heap can be random, the article number of lattice be fallen into without accurately controlling, then conveyer can also connect
It moves continuously, the supply of article also can be continuous.Lattice is distributed in row and column fashion, makes each stack of articles defeated
The time and position for sending device to export can be determined in advance, and the stack of articles in the same stack of articles combination can in output
Easily collected.It is realized by the way that conveyer is periodically started and is stopped in compared with the existing technology article point
Heap, and the period limitation for starting and stopping itself just limiting to overall throughput, the present invention clearly can make article stream more smoothly
And provide bigger production capacity room for promotion.
Stack of articles is arranged in feed surface in terms of rows and columns, and the row's stack of articles of conveyer laterally arranged is one
Column, row's stack of articles of the conveying direction arrangement of conveyer are a line, and stack of articles is in the form of more than a column and/or more than a line
It is distributed in the feed surface of conveyer.The present invention allows to include that the mode of line scanning realizes the number of article with two kinds of forms of taking pictures
It calculates.
It is described to pave as single layer, it can be realized by the way that the forms such as vibrating mechanism or scraper plate are added in conveyer, article
What single layer can be convenient carries out capture to stack of articles by way of line is scanned or taken pictures, and then can be clear by analysis image
The number for knowing article of Chu.
Discrete type article distribution method of the invention can be learnt the accurate article number of stack of articles with view finding method and be led to again
The form for crossing combination obtains the stack of articles combination of different numbers, can be widely used in discrete type article distribution field, and phase
To assess article number compared with coming than in the prior art using the mode of weighing and with known article average weight, then carry out group
Operation is closed, the present invention can obtain the stack of articles combination of accurate number, and allocative efficiency is high.
Embodiment 2
A kind of distribution method of the discrete type article based on the mode of making up the difference, including
Step 1: article is paved as single layer and is divided in the feed surface of conveyer to conveyer article without interruption
It is divided into stack of articles, stack of articles is conveyed to the output end of conveyer；
Step 2: counting to the number for the article that each stack of articles is included, the article in each stack of articles is obtained
Number；
It is not more than Step 3: finding at least one included article number in the stack of articles being counted on the transport surface
The stack of articles of target item number combines, and by each stack of articles searched out combination when conveyer exports, is held using one
Device receives a stack of articles combination；And calculate the article number of the stack of articles of the combination and differing for target item number
Number,
Step 4: can accurately export the feed supplement mechanism of the article of any number by one, divide in Xiang Suoshu container
Article with the difference number
It is described to be counted as by stack of articles capture in the step 2, and to obtained image analyzed with
Obtain the article number in stack of articles.
In the step 3, any one stack of articles is not selected yet to an article in the output end for leaving conveyer
When heap combines, the stack of articles is rejected in output.
In the step 3, when the stack of articles being counted newly is added in feed surface, the object being 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
The stack of articles for being selected and having combined to a stack of articles is free of in the stack of articles of counting.
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 be counted in stack of articles of feed surface find stack of articles combination.
In the step 3, when finding stack of articles combination, the sequencing of the output end of conveyer is left with stack of articles
Operation is carried out, preferentially formerly leaves in the stack of articles of conveyer output end and finds.
The present invention be article is made it is rationed, can be more effective 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 when more for the stack of articles number of selection on feed surface, when
In can be realized according to a target value export article chance it is also just higher.In the method, stack of articles is on a conveyor
Constantly flowing, new article can constantly fall in conveyor surface and form stack of articles, also constantly exported, and
It says, although the number for the stack of articles that can be selected is limited, but for the numerical value of article number used in combinatorial operation
Be it is continually changing, suitable combination just also can constantly occur, compared with the existing technology in using temporary storing bin carry out storing products
Heap new a numerical value will occur when making combinatorial operation, just to need to put into new article to temporary storing bin, and part has carried in the middle
Have the temporary storing bin of article will occur quantity superposition, and finally occur quantity overflow (i.e. article number in a temporary storing bin is big
In target number) the case where.This method, which clearly avoids, occurs asking for quantity spilling when making rationed in the prior art
Topic.
Certainly, the stack of articles not being selected will be removed that (stack of articles being removed can be cycled back in output
Loader use), be a discount to production capacity, but as long as keeping the ratio of stack of articles for needing to be removed sufficiently small, in conjunction with
The upper usefulness in terms of production capacity, is that the present invention can provide more superior comprehensive production capacity.And it is obvious that quantitative
Under the premise of distribution, must have some in the stack of articles of conveyor surface is that cannot be used in selected stack of articles combination
In, but can be reached by arrangement below and lower the ratio for needing the stack of articles rejected:
Stack of articles is received simultaneously using more containers.Following example illustrates the influence of this factor:
Figure one shows the stack of articles for having uniline to arrange on a conveyer, and when output same time is only by a container
It receives, so next stack of articles combination must can just be exported after stack of articles combination output completely, according to 50 mesh
Number distribution is marked, 4 stack of articles for needing to be removed occurs.
Figure two shows the stack of articles of same a line, but while exporting same time can be received by most two containers, not had
There are stack of articles needs to be removed.
Use lesser stack of articles.Following example illustrates the influence of this factor:
Figure three shows that the stack of articles for having 4 rows on a conveyer, the article number of each stack of articles are random between 5~12
Variation, when output same time by that can be received by two containers, distribute, in 17 exported first according to 50 target number
There are 4 stack of articles needs to be removed in column stack of articles.
Figure four shows same 4 row stack of articles, and most two containers receive simultaneously, and according to 50 target number point
Match, but the size reduction of stack of articles be change at random between 1~9, do not needed in the 17 column stack of articles exported first by
The stack of articles of rejecting.
Allow to make up the difference to the stack of articles combination of output to reach target number.Following example illustrates this factor
It influences:
Figure five shows the size distribution of a stack of articles same as figure three, equally can be by most two with the same time
A container is to receive 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 is not more than 50, there is no the stack of articles for needing to be removed in the 17 column stack of articles exported first.
Reach the rationed of article using the method made up the difference to the combination of the stack of articles of output, above explanation it
In, hence it is evident that the needs of rejection of commodities heap can greatly be reduced by finding out to allow to make up the difference, and it is opposite for allowing to make up the difference with rejection of commodities heap
, it is more to allow to combine stack of articles number of making up the difference, and needs the chance of rejection of commodities heap just smaller, vice versa.So one
Determine the permissible of degree to make up the difference in number, is possible to completely eliminate to the needs of rejection of commodities heap.Make up the difference is to need
The working time is wanted, in ideal conditions, number of making up the difference should be the smaller the better, so just for the duty requirements of feed supplement mechanism
Can be lower, and in practical applications, lower the needs of rejection of commodities heap by using above-mentioned mentioned different arrangements, and
Allow the number of making up the difference that can be reasonably easily reached by the prior art, can accomplish to completely eliminate rejection of commodities heap
It needs.And compared with the existing technology in, Chinese invention patent, a kind of article disclosed in number of patent application " 201210509818.7 "
Distribution method and device, be used in the same manner the mode made up the difference to reach target number, the present invention significantly provides following technology
Advantage:
In the present invention, distributing number for the first time can be closer to target number, while the case where quantity spilling will not occurs.
In the prior art, differing for distribution number and target number has been to deposit random for the first time, needs guarantee not to be more than target number, just
Need to receive biggish number of making up the difference.In the present invention, although the article number of stack of articles be it is random, by combination after,
Randomness between stack of articles and stack of articles is just cancelled out each other, can finally obtain one can be 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 combines
Article number just should not be more than 15 with the difference of target number and (if an article number combined is greater than 15, just should
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
Generally the centre of the variation range of stack of articles (i.e. 10).But due to that can be selected consciously when extracting combination, and
Alternative combination it is enough number of when, this phase difference just should be averaged in a lower range.And it is true
On, it is easy to as can be seen that in the method because combined selection be it is conscious, can be obtained when extracting combination and mesh
The case where identical chance of mark number is significantly existing, and quantity is overflowed simultaneously will not occur.On the contrary, in the prior art
In, it is fundamentally that cannot allow the case where sendout just obtains target number for the first time, because of this situation once occurring, just means to count
The case where amount is overflowed must also will appear.
In the present invention, sendout has learnt that feed supplement mechanism just has before article is actually exported and distributed for the first time
The sufficient time prepares, and in fact, when having existed multiple stack of articles be selected on a conveyor and combining, feeding machine
The structure stack of articles group that the saved time makes up the difference used in multiple numbers that small number can be made up the difference is closed, and the work of feed supplement mechanism is made
More efficiently.On the contrary, in the prior art, number of making up the difference just is obtained after the stack of articles output distributed for the first time, feeding machine
Structure needs the short time to react and completes output of making up the difference, to avoid next cycle is influenced.Meanwhile making up the difference the time in different cycles
Also cannot be complementary, even and if says that feed supplement mechanism fulfils output of making up the difference ahead of schedule in once small number is made up the difference, saved when
Between be also not used in the making up the difference in work of another period.In this way, the speed of feed supplement mechanism is just needed by maximum number of making up the difference
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 previously mentioned, in the present invention supply of article be it is continuous, compared with the existing technology in the stack of articles distributed for the first time
It is to be realized by starting and stopping conveyer, the present invention provides more preferably production capacity and more smooth running.
