Object or the article of this green tape flaw etc., it is all in need to be detected in counting process.
In some distribution tasks, completing container must not be comprising the article less than predetermined quantity.For example, when distributing certain medicines
When ball, it may be necessary to which complete treatment cycle is provided, it is therefore necessary to which the article of at least predetermined quantity is provided in each container.
On the other hand, assigned article may be expensive, so if too many container includes to be more than predetermined quantity
Article, then it increases supplier or the production cost of package mechanism of article.
In many dispensation machines, article is conveyed along conveyer, and is divided into multiple single-row ends in conveyer
It falls and collects in a reservoir, during the falling process, object each column article is counted one by one by photoelectric sensor, it is pre- when reaching
When fixed number amount, with physical separation in preventing article from falling into container on the channel of each column, inherently efficiency is lower for such mechanism, because
It is divided on a conveyor for, article multiple single-row, the article that can be conveyed in centainly conveying area must be than not needing handle
Article be divided into it is single-row lack, meanwhile, be also required between the column and the column keep certain distance to install mentioned-above photoelectric sensor

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further described into column.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 1
A kind of efficient distribution method of discrete articles, as shown in Fig. 1~Figure 15, including
Conveyer cycle movement is driven, article is conveyed with the state of single layer to the end of conveyer；Each conveyer
Starting, conveyer stop being a start-up period；
Conveyer forms at least one individual stack of articles, the object of each stack of articles in the article that a start-up period exports
Product quantity is by accurate metering；
Continuous capture is carried out to a capture region for being located at conveyer latter end, the capture region is set in conveyer end
Before end, across the conveying direction of conveyer, each article is before being exported, by capture region and at least by capture one
Secondary, article also leaves conveyer when leaving capture region；
The image got is handled, in real time to determine the number of articles of output.
The stack of articles of a combination is found, the number of articles of each combined stack of articles is identical as destination number, by one
Combined article Heap Allocation is to container.
Conveyer cycle movement of the invention refers to that conveyer stops two movements with conveyer starting and conveyer and is
A cycle drives the article of conveyer to convey, and article stream can be carried out disjunction by cycle movement, form stack of articles.
Capture method of counting of the invention, when each article passes through capture region, image is in acquired image
Occur, position of the article in the every frame image continuously obtained is tracked, when the image of the article disappears in the image of acquirement
When, it counts and adds one.It is assumed that the length of article is L, the length in capture region is W, and capture frequency is f, goods speed V, then object
When product lead to capture region, at least it is by the primary condition of capture,
W>V/f
And article is at least by the primary condition of complete capture,
W>(V/f)+L
One is left the article in capture region completely, sufficient at a distance from the outlet end of conveyer in the outlet end in capture region
It is enough it is small in the case where (less than the center of gravity of article and the minimum range at article edge), the center of gravity of article, which will be, leaves conveyer table
Face, gravity will enable the article leave conveyer automatically, so, no matter conveyer be drive or stop state, it is complete
The quantity for leaving the article in capture region entirely, is equal with the number of articles that conveyer is exported.
During conveyer exports stack of articles, it can be not required to accurately control the quantity of output article, only need to accurately count
Number, in this way, the efficiency of output can be faster.The number of articles of stack of articles be it is random, pass through find one combination article
The method of heap, makes randomness cancel out each other, and finds out the total number of items stack of articles that combines equal with destination number.And it is seeking
During the stack of articles for looking for a combination, it is known that the number of the stack of articles of number of articles is more, obtains the probability of a combination
Just bigger.
Article is single layer tiling state motion always during transportation, each period of conveyer exports at least one object
Product heap is realized when to export more than one stack of articles by following methods:
As shown in Fig. 5 to Fig. 8, one) for using multiple conveyer transporting articles side by side, corresponding one group of each conveyer is temporary
Storage, each conveyer is in the article that each the start-up period is exported by a reception in corresponding buffer, Mei Gerong
It receives the buffer for having article, can all be labeled number of articles, i.e., the number of articles of the stack of articles stored in it, controller is according to mesh
Mark number of articles finds the buffer of one or more than one for meeting the destination number just, by manifold, by buffer
Interior stack of articles, which releases to be pooled to container and can be completed, to share out the work.The number of articles for releasing the buffer of stack of articles is reset, and
Continue to new stack of articles.
Multiple conveyers side by side independently control the start-up period of each conveyer, the start-up period of a conveyer with
The conveyer it is not identical to last the start-up period.Every time when one conveyer of driving, by the starting for changing the conveyer
The length of time and probably control the magnitude range to exported stack of articles, can be in response to the article number of all buffers at that time
The size distribution of amount controls the magnitude range of the stack of articles newly exported complementaryly, finds combination probability to increase, improves and divide
With efficiency.
Under the conditions of the buffer corresponding to each conveyer is limited, buffer for being loaded with stack of articles can be after
New stack of articles is received in continued access, with improve transfer efficiency and find a combination stack of articles probability, existing article it is temporary
Storage is after receiving a new stack of articles, number of articles and new received object that the number of articles of label marks before being
The superposition of the number of articles of product heap, and when the number of articles of label is greater than destination number, which is just considered as quantity and overflows
Out, it needs to be removed.It is that one of the allocative efficiency of whole system is lost that quantity, which is overflowed,.It can opened with independent control conveyer
In the case where stopping, article can be exported by one conveyer of pause, it is vacant until having in its corresponding one group of buffer
The case where just starting when buffer, being overflowed to avoid quantity.
As shown in Fig. 9~Figure 11, two) separation conveyer deferent segment, formation article output channel, each the start-up period, often
Channel exports a stack of articles, and the stack of articles of adjacent channel output is non-interference.Each output channel is one group corresponding
Buffer, the stack of articles that every channel of each the start-up period is exported is by a reception in one group of corresponding buffer.
Using the form for being separated out article output channel on a conveyer, multiple stack of articles can be exported, find group to improve
The efficiency of conjunction.
The present invention can also be further, makes the output channel of the single-row article of article output channel, can easily make
Article improves the accuracy of identification and detection in image saliency.
Capture region: each primary by least complete capture by the article in capture region.
By in image article image and the image of preset article compare, judge comparing result, work as comparing result
When inconsistent, record the article and reject.
Article of the invention is rejected, and can be used and directly be rejected the underproof article, or in conveyer output
The article is rejected using an eliminating passage, or the container that stack of articles belonging to the article is finally collected to entirely is picked
It removes.
Article image in image and the shape of the image of preset article, color, size is any when requiring different, determines
It is inconsistent for comparing result.
Each stack of articles is received by an independent buffer, when searching out the stack of articles of a combination, collects the group
The article of the stack of articles of conjunction is exported to a container, and continuously supply container is to station is distributed, to receive the article for collecting output.
When previous container leaves distribution station, the latter container does not reach distribution station also, the temporary article collected.
Continuous container will appear during transportation, be assigned, but container does not reach asking for output bit also
Topic, can use temporary function at this time, keep in the article collected, that is, when container is also not up to output bit, system
The article for continuing the destination number of distribution next time is avoided by until container is just allocated the wasted time in place.
The present invention distribution method that there are also different when can not find combination, specifically:
1. when can not find the stack of articles of a combination, by empty buffer one new stack of articles of reception, and after
Continue the stack of articles that a combination is found in the buffer of all existing articles.By increasing the quantity of stack of articles, raising is found
The probability of the stack of articles of one combination.
2. when can not find the stack of articles of a combination, the buffer of one existing article receives a new stack of articles,
Number of articles in the buffer be original article and new stack of articles and, and continuation is in all buffers for being loaded with article
Find the stack of articles of a combination.The number of articles of stack of articles in buffer is obtained using superposition quantity, and then obtains new group
It closes.
3. all items in one buffer are transferred to another and are kept in when can not find the stack of articles of a combination
Device, the buffer being emptied receive a new stack of articles, and the new number of articles for receiving the buffer of transfer article is it
The summation of the quantity of original article and the number of articles being transferred continues to find a group in all buffers for being loaded with article
The stack of articles of conjunction.
4. selecting a total number of items to be less than a combination of destination number when can not find the stack of articles of a combination
Stack of articles releases all items in the buffer of the combination to container, and differs article to container allocation and number of targets.
The total number of items of selection and the difference of destination number are between the 1%~10% of destination number, certainly other ratios
It can also be with generally between 1~10 article.
It is described to container allocation and target when finding the stack of articles of this combination with destination number when differing article number
Several difference articles is realized by following two methods:
The conveyer 1. setting is made up the difference, conveyer of making up the difference can export single article, supply difference article.
2. the number of articles of difference is set as new destination number, new destination number subtracts for former destination number has divided
The number of articles matched is found the stack of articles of a combination in the temporary storing bin of existing article, is sought based on new destination number
When finding the stack of articles of a combination, the stack of articles of the combination being distributed, when can not find the stack of articles of a combination, can will be differed
Number of articles be set as new destination number, continually look for combining, until to the complete original destination number of the container allocation
Article.
As shown in figure 12, capture region of the invention includes that following methods realize counting；The length side in the capture region
To including input lateral boundaries and output lateral boundaries, inputs lateral boundaries and be set on conveyer, output lateral boundaries are set to conveying
Before the line of device end, center of gravity of the lateral boundaries at a distance from conveyor end line less than article is exported at a distance from its most short outer diameter,
It inputs lateral boundaries and passes through capture before being exported with the maximum length for being greater than article at a distance from lateral boundaries, each article is exported
Region is simultaneously at least primary by capture, and article also leaves conveyer when leaving capture region.
Capture region is located at conveyor surface, can completely realize tally function, and detects picture images conveniently, identification
Rate is high.
As shown in figure 13, capture region of the invention be also designed to input lateral boundaries be set on conveyer, export
The boundary of side is overlapped with conveyor end line, and input lateral boundaries are greater than the maximum length of article at a distance from output lateral boundaries,
Each article, by capture region and at least primary by capture, also leaves defeated before being exported when article leaves capture region
Send device.
As shown in figure 14, capture region of the invention be also designed to input lateral boundaries be set on conveyer, export
The boundary of side is set on the outside of conveyor end line, and input lateral boundaries are greater than the maximum length of article with exporting at a distance from lateral boundaries
, each article is before being exported, and by capture region and at least primary by capture, article also leaves when leaving capture region
Conveyer.
When using the above method, the setting process that capture region is set can be made to greatly simplify, and reduce machine operation
Interference, the present invention input the distance between lateral boundaries and conveyor end line greater than article maximum length, to distinguish two
A article image continued through, and allow a complete article image that can present, so as to realize contoured article and
The detection of size.
The present invention also provides a kind of methods using inertia deferent segment to improve allocative efficiency:
Outlet section in the capture region of each conveyer is provided with inertia deferent segment, and the article of inertia deferent segment is conveying
Device can be exported after stopping, when the number of articles exported plus in inertia deferent segment number of articles and one or more it is temporary
When the sum of number of articles in storage is identical as destination number, stop the conveyer.
Inertia deferent segment is a part, that is, inertia output area in capture region, is referred in each the start-up period, when
