DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an article distribution control device that controls a large number of articles so that they are distributed in a predetermined manner.

製品の場合、個々の製品が規定重量以上が詰つて

For example, in the case of a product that is packed with a certain amount of granules in a bag and shipped, if each product weighs more than a specified weight, it will be shipped as a good product and there will be no problem. but,
Depending on the product, up to a specified percentage of the total weight may be considered acceptable even if the weight is below the specified weight.

これを第1図、第2図によつて説明する。 This will be explained with reference to FIGS. 1 and 2.

Figure 1 shows the distribution of the number of pieces with respect to weight, M 1 and M 3 are defective weight values, and anything below or above this, that is, belonging to the area, should be considered good for any reason. is an impossible value. M2 is a good weight value, and anything greater than this and less than a bad weight value M3 , that is, a product belonging to the area, is considered a good product and has no problem. Now,
The problem is how to handle products of weight x that belong to the range M 1 <x < M 2 , that is, the range. As mentioned above, instead of treating all products in the range of M 1 < x < M 2 as defective, if you want to treat the number of products within a specified percentage of the total number of accepted products as non-defective products, in a continuous series of operations, The problem with this invention is how to process it. As a result, as shown in Figure 2, among the products in the range of M 1 < x < M 2 , the shaded area A is considered defective, and the non-shaded area B is considered good. The number of portions B that has been removed may be within a specified percentage of the total amount.
However, since the continuous flow of products must be automatically weighed and immediately determined as good or bad, the total amount cannot be unambiguously determined in the middle of the process.

FIG. 3 shows an embodiment of the invention. In this figure, V is a belt conveyor, which is configured so that products W are sequentially conveyed. 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 acceptable products W1 and rejected products W2 . 3 is a region classifier, 4 is an AND gate, 5 is an OR gate, 6 and 7 are cumulative counters, 8 and 9 are adders, 1
0 is a divider and 11 is a comparator.

次に動作について説明する。 Next, the operation will be explained.

領域分類器3では、重量測定器1の出力に応じ

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 shown in FIGS. 1 and 2. Because products in this area are of good quality,
The good product command P passes through the OR gate 5, and the sorting machine 2 is operated at a predetermined timing to determine a passing product W1 . Since the product in area 1 is a rejected product W2 , the non-defective product command P is not issued, and therefore, the sorting machine 2 sorts the rejected product W2 at that timing.

次に領域の場合は、判断して合格、不合格を

Next, in the case of areas, it is necessary to judge and decide whether to pass or fail. Therefore, the number N of products that have been determined to be acceptable products W 1 in the area so far is entered in the cumulative counter 6, and 1 is added to this to obtain "N+1".
The adder 8 outputs as . On the other hand, the cumulative counter 7 contains a cumulative total M of the number of products W1 that have been determined to be acceptable up to that point, and the adder 9 adds 1 to this and outputs it as "M+1". Divider 10 divides the outputs of adders 8 and 9 to give (N+1)/(M+1)
make. The comparator 11 compares the preset tolerance α with the above (N+1)/(M+1), and when N+1/M+1≦α, outputs (deems a good product), opens the AND gate 4, and the output is It is added to the sorting machine 2 from the OR gate 5 as a non-defective product command P.

このようにして、順次送られてくる製品Wを、
順次、合格品、不合格品に選別する。
In this way, the products W that are sent sequentially are
The products are sequentially sorted into acceptable products and rejected products.

FIG. 4 shows another embodiment of this invention.
This embodiment is an example in which each of the allowable rates α 1 to α 3 is further determined within the range according to the weight of the product W and the products are selected. 20A, 20B, and 20C all represent selection circuits, which are composed of 4, 6, 8 to 11 shown in FIG. And or gate 5 and cumulative counter 7
is commonly used for each selection circuit 20A to 20C. Furthermore, three types of sorting machines, 2A to 2C, are provided. According to this configuration, each of the sorters 2A to 2C can sequentially classify the products into acceptable products W 1 and rejection products W 2 within the range of allowable rates α 1 , α 2 , α 3 .

FIG. 5 is a diagram illustrating another example of the application of the present invention. For example, when making cheap particles into a large lump using an expensive adhesive, determining the ratio of each particle size to be mixed in will make the strength more efficient for the amount of adhesive. , the above ratios must be determined continuously, but the present invention is effective in such cases.

That is, in FIG. 5, 21 is a large particle, 22
is a medium particle, 23 is a small particle, and the ratio of each particle is 1:1:4. In such a case,
Particles 21, 22, and 23 of each size must be sorted and mixed. One method is to sort the materials and then store them, then sample and mix the materials in each proportion, but this requires a large amount of storage space. For this reason, the article distribution control device of the present invention is extremely advantageous, since sorting and mixing are already performed no matter what time the sorting is stopped after the start of the sorting.

In addition, although the case of weight sorting was explained in the above embodiment, the present invention may also be applied to other measured quantities, such as length, temperature, etc. Furthermore, the terms "acceptable products" and "rejected products" are used as a standard, and basically it is sufficient if a predetermined classification can be performed.

As described above, the present invention is equipped with two cumulative counters, one of which counts the number of pieces that fall into a predetermined area out of the total number of pieces, and the number of pieces that are in the judgment area but are determined to belong to the predetermined area. The number of pieces judged to belong to a predetermined area in a certain output is accumulated, and when an output corresponding to the judgment area comes out, an adder is provided that adds 1 to both accumulation counters, and the outputs of both adders are added to a divider. After dividing the ratio by It has the advantage that it can be done accurately and can be completely automatically classified into a predetermined distribution.
