Abstract

PURPOSE:To ensure the automatic sorting of articles with a prescribed distribution, by adding 1 to the value of each cumulative counter, dividing the output of both adders and comparing the quotient with the set allowable value in case when an output is equivalent to a region of decision. CONSTITUTION:An article W is carried on a belt convayor V, and the weight of the W is measured by a weight measuring instrument 1. A selector 2 selects the articles W into nondefective articles W1 and defective articles W2. Here a region sorter 3 sorts the weight of the W in accordance with regionsI-IV as well as to the output of the instrument 1. The articles in the region III are selected 2 to the articles W1, while the articles in the regionsIand IV are selected 2 to the articles W2 respectively. In the case of the region II, the adders 8 and 9 are provided to add 1 to the value of each of cumulative counters 6 and 7. The outputs of both adders 8 and 9 are divided by a divider 10, and the output of the divider 10 is compared with the allowance factor which is previously set. Then an article W is decided nondefective and delivered from a comparator 11 when the output of the divider 10 is less than the allowance factor.

Description

【発明の詳細な説明】 この発明は、多数の物品を所定分布になるように制御す
る物品分布制御装置Ｋｌｌするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an article distribution control device Kll that controls a large number of articles so that they are distributed in a predetermined manner.

例えば、ある粒体な一定量袋に詰めて出荷する製品の場
合、個々の製品が規定重量以上が詰っていれば良品とし
て出荷され問題はない、しかし、製品によっては全量の
うち規定％までは規定重量以下でも合格として堆扱って
よいものもある。For example, in the case of a product that is packed in a bag containing a certain amount of granules and shipped, if each individual product is filled with a specified weight or more, it will be shipped as a good product and there will be no problem. However, depending on the product, up to a specified percentage of the total amount Some items may be considered acceptable and can be treated as compost even if their weight is less than the specified weight.

これを第１ＩＩ、第２図によって説明する。This will be explained with reference to FIG. 1II and FIG.

第１ＩＩは重量に対する個数の分布な示すもので、Ｍ、
、Ｍ、は不良重量値で、これ以下２以上のもの。The first II shows the distribution of the number of pieces with respect to the weight, M,
, M is the defective weight value, which is less than or equal to 2 or more.

重量値で、これ以上で不良重量値Ｍ。That is, area 1. Items belonging to IVK have values that cannot be considered good for any reason. M is the storm weight value, and anything greater than this is a bad weight value M.

においては全量は一義的に定まらない。Those below, that is, those belonging to the area IK, are considered to be good and have no problem. Now, the problem is how to deal with the range of Ml < x < y, that is, the weight 1 discipline item belonging to region I. As mentioned above, M%<s<
Rather than eliminating all products in the range of M@, if you want to treat the number of products within a specified percentage of the total number of passed products as non-defective products, it is important to consider how to circle them in a continuous series of operations. This is a problem with this invention. As a result, as shown in Figure 2, among the products in the range M, (z < y,
The shaded part ^ should be considered defective, the non-hatched part B should be considered good, and the number of parts B should be within a specified percentage of the total quantity. It is necessary to automatically weigh the products that are continuously flowing in and immediately determine whether the product is defective or defective.
In this case, the total amount is not uniquely determined.

装置を提供することを目的とする。This invention was conceived in consideration of Kamimachi's point, and an object of the present invention is to provide an article distribution control device that can automatically perform control to achieve a predetermined distribution.

以下この発明について説明する。This invention will be explained below.

器、１０は割算器、１１は比較器である。FIG. 3 shows one embodiment of the invention. In this figure, ■ is a belt conveyor pair, and the products W are conveyed sequentially.
It is composed of Reference numeral 1 denotes a weight measuring device that sequentially measures the weight of the product W. 2 is a sorting machine that sorts the products into 1 acceptable product W and 1 rejected product W. 3 is region-classifier, 4 is AND gate, 5
is off-gate, 6. 7 is a cumulative counter; 3. s is an adder, 10 is a divider, and 11 is a comparator.

。Next, the operation will be explained.The region classifier 3 classifies the weight of the product W according to the output of the weight measuring device 1 according to the regions I to 1■ of the irises 1 and 82. Since the products in the region are good products, they pass through the OR gate 5v and become a good product command P, which causes the sorting machine 2 to operate at a predetermined timing and makes them passable products W. Area 1. Since the item IV is a rejected item Wt, a non-defective item command P is issued, and therefore, at that timing, the sorter-2 sorts out the rejected item W.

The adder 8 adds 1v to this and outputs "N+IJ".

The adder 9 outputs +IJ. In the divider 10,
Divide the output of adder - and 9, (N+1)/(N+1)

・When N+1, it is determined that the product is good and outputs an output), AND gate 4 is opened, and the output is added to sorter-2VC from OR gate 5 as good product command P. 'In this way, the products Wv are sent one after another.

順次２合格品、不合格品に選別する。The products are sequentially sorted into 2 passing products and 2 rejected products.

が書わめて有利、である。FIG. 5 is a diagram illustrating another example of the application of this invention.
For example, when using expensive adhesive in the form of cheap particles and making it into a large lump, determining the ratio of each particle size to be mixed in will effectively increase the strength relative to the amount of adhesive. In such a case, the above ratio must be determined continuously, but the present invention is effective in such a case.
・In other words, in Figure 5, 21 are large particles, 22 are medium particles, and 23 are small particles, and the proportion of each particle is:
The ratio will be 1:1:4. , in such a case, particles of each size 2 j, 2. ．． 2. 2.3 must be sorted and mixed. There is a way to stock the traps after sorting and then sample and mix them in each proportion, but this requires a large stocking area. child? )For,
The article distribution control device of the present invention is extremely advantageous in that sorting and mixing are already performed no matter what time the sorting operation is stopped after the sorting operation is started.

点がある。As described above, the present invention is provided with two cumulative counters, one for accumulating the number t of the total number of pieces that fall into a predetermined area, and the other for accumulating the number of pieces judged to belong to a predetermined area based on the output in the judgment area. Then, when an output corresponding to the judgment area is obtained, an adder is provided that adds 1v to each product counter of both systems, and the output of both adders is divided by a divider, and then the comparator is used to set the value in advance. By comparing with the tolerance rate, it is determined whether the output corresponding to the judgment area belongs to the predetermined area, so even if the products are flowing sequentially, the judgment can be made accurately, and all (automatically in the predetermined distribution) It has the advantage of being able to be classified.
