Realizing method for quantitative grain counting and device thereof

Abstract

The invention discloses a realizing method for quantitative grain counting and device thereof, comprising a control system, a feeder, a conveyor, a camera, a memory hopper and a retainer, wherein said control system comprises an image processor, a combined calculation processor and PLC (programmable logic controller); said feeder feeds material to the conveyor in scattered way; at least one layer of memory hopper is set below the conveyor; the camera and the image processor performs image data collection and analysis and grain calculation on material on the conveyor, and delivers the material to the corresponding memory hopper, wherein the material grain number is corresponding to the memory hopper; the combined calculation processor performs combined calculation on the material amount in the memory hopper and compares it with the preset target grain number, and selects the memory combination with a grain number which is closest to the target grain number within allowed deviation range, and discharges the material in the memory hopper. The invention combines the batch CCD grain counting technology with uncontrollable grain number with combined calculation technology to largely raise the precision and speed on quantitative grain calculation.

Description

technical field [0001] The invention relates to a grain counting machine, in particular to a quantitative grain counting method and device combining CCD grain counting technology and combined technology. Background technique [0002] The counting machine is a kind of counting device, usually for food, medicine, seeds, electronic components, plastic parts, metal parts and other granular items, counts the corresponding packaged objects according to the packaging requirements of the set number of grains, this kind of equipment Widely used in various fields such as production and commerce. In order to realize quantitative packaging with the number of particles as the unit (such as 100 pills, 1000 seeds, etc.), counting method, volume method, and weighing method can be adopted. [0003] The counting method is the most direct method, the most accurate, but the slowest and the largest investment. [0004] The traditional counting equipment adopts infrared sensing method, which is...

Problems solved by technology

The advantage of this kind of equipment is that the precision of quantitative counting is high, but the disadvantage is that the speed is slow, and only one material can pass through the infrared light curtain at a time, otherwise even if more than two materials pass through at the same time, only one ON will be issued. / OFF signal, resulting in inaccurate final counting results, especially when the cost of a single material is high, it will cause a large loss to the manufacturer

However, in actual operation, the uniformity of individual weight of many materials varies greatly. For example, the individual weight of corn seeds may be doubled due to moisture content, particle size differences, and different shapes. Plastic parts may vary due to moisture content changes, shape errors, and material densities. Its individual weight may also vary by 20%

When such materials are counted by weighing technology, the accuracy will be greatly reduced
