The material counting device 100 shown in fig. 1 includes a material distributing device 101, a material detecting device 103 and a control device 104, wherein the material detecting device 103 is arranged at the end of the material distributing device, and the control device 104 and the material detecting device 103 have the following specific functions:

the material distributing device 101 is used for transporting materials;

The material arranging device 102 is arranged below the material distributing device 101 and is used for arranging the materials into materials with certain orientation;

the material detection device 103 is arranged at the tail end of the material sorting device 102 and used for scanning the materials to obtain projections of the materials;

The control device 104 is used for carrying out corrosion treatment and calibration on the projection of the material to obtain a projection parameter value of the material; determining whether the material is qualified according to the relation between the projection parameter value of the material and a preset standard parameter range; and counting the materials under the condition that the materials are qualified materials.

This application can carry out the analysis through the projection to the material and confirm whether the material is qualified material, and then whether the definite count that whether can realize the count to irregular material.

The materials may overlap due to the materials themselves (for example, materials with viscosity may stick together), or during the transportation of the materials, the overlapping of the materials may occur, which may result in that when the projection of the materials is obtained, the crossed projection may be obtained, and how to perform accurate counting is a concern.

therefore, the projection of the materials is determined whether to be a single continuous projection or not after the projection of the materials is obtained, the projection of the materials is judged to be a single continuous projection or a cross projection, and then whether the materials are qualified materials or not is judged according to the two conditions.

specifically, the control device 104 determines whether the material is a qualified material, and the specific process of counting the material when the material is a qualified material is as follows:

(1) determining whether the projection of the material is continuous;

(2) Determining whether the projection parameter value of the material is in the standard parameter range or not under the condition that the projection of the material is a single continuous projection;

(3) And under the condition that the projection parameter value of the material is within the standard parameter range, determining that the material is qualified, and counting the material, wherein the counting value is the number of projections of the material.

(5) connecting the centers of all inscribed circles in each of the M cross projections into a straight line to obtain M straight lines;

(6) and under the condition that N straight lines are intersected in the M straight lines, determining that N qualified materials exist in the materials, and counting the materials, wherein the counting value is N, and N is an integer which is larger than 1 and smaller than M.

wherein, the processes (1) to (3) are the processing processes of the control device when the projection of the material is a single continuous projection, and the processes (4) to (6) are the processing processes of the control device when the projection of the material is a single continuous projection.

For example, the projection of the material is recorded by the material detection device 103 and transmitted to the host computer of the control device; the method comprises the following steps that a host automatically reads projection parameters of materials, corrosion treatment is carried out on the projections by using a function, if single continuous projections are obtained, the host enters the next step of function operation, the length value, the width value, the minimum and maximum external rectangular values of the projections of the materials are calibrated, and finally related parameters are given to the projections of each material; if two or more crossed projections are obtained after corrosion treatment, the host machine calibrates all inscribed circles in each crossed projection by using a set standard width range value as a diameter through function operation, then connects the circle centers of the inscribed circles into a straight line, and if the two straight lines are crossed, the host machine judges that the crossed projections are two qualified materials, so that the materials which are bonded and overlapped are selected and counted.

In this application, when the projection is single continuous projection, can confirm whether the material is qualified material through the relation of comparing this projection parameter value and standard parameter, and then decide whether to count. When the projection is a plurality of crossed projections, the inscribed circle is arranged in each crossed projection, and the actual number of the materials is judged according to the intersection condition of the straight lines of the inscribed circle, so that the materials which are bonded and overlapped can be selected and counted.

For example, the materials having the first projection feature value, the materials having the second projection feature value, and the materials having the third projection feature value may be classified separately, or the materials having the first projection feature value and the materials having the second projection feature value may be classified into one type, and the materials having the third projection feature value may be classified into another type. Or classifying the materials with the first projection characteristic value into a first class of materials, classifying the materials with the second projection characteristic value into a second class of materials, and classifying the materials with the first projection characteristic value into a third class of materials.

specifically, materials with large projection characteristic values can be classified into one type, materials with moderate projection characteristic values can be classified into one type, and materials with small projection characteristic values can be classified into one type. It should be understood that the materials can be classified into three categories, and a finer classification level can be set according to the projection characteristic value of the materials, so as to classify the materials more finely and/or more variously.
