The process of controlling the mass of piece products on pneumatic devices

Abstract

The principle of recognition based on the use of the properties of a thin gas layer and the supporting surface of equipment, which provided the creation of a number of universal devices capable of solving the problem of sorting and culling piece parts by weight. A promising method of recognition by the generalized criterion (specific load) is presented on the basis of which two new orientation criteria were obtained (the area of the support surface of the product and its mass) are obtained on the basis of this method. It is proved that the gas layer has a high sensitivity to changes in the characteristic parameters of products, i. e. is able to recognize them. There is a need to develop automatic sorting and rejection devices for a class of small piece products with implicit design features and having understated physical and mechanical properties, as they can not apply to traditional means of automation, loading and orientation operations with mechanical grips, weighing in the stream. There are significant difficulties in the culling of piece products with bevels, shells, etc., which led to the creation of devices that provide manipulation of a wide variety of sizes of specific products with a decrease in dry mechanical friction between the product and the bearing parts of the equipment. Classification of specific product types and configurations of circuits pneumatic devices that use the effects in the thin gas bearing strata (the working surfaces and air chambers, view their movements, technological capabilities). The bases of recognition of products by mass on a gas layer with the use of various working surfaces, which formed the basis for the creation of a number of new sorting devices with a high level of flexibility, are proposed..

“…В приборостроении, разработке медицинской техники, химической многоассортиментной промышленности (фармацевтической, парфюмерно-косметической), пищевой и других возникают значительные сложности в манипулировании специфическими деталями и готовой продукцией, например, при сборке изделий, узлов и агрегатов [1][2][3][4][5]. Зачастую это связано со спецификой деталей, к которой можно отнести: 1) свойства материала (например, заниженные физико-механические характеристики: хрупкость, ломкость и т.…”
