Abstract
On many industrial objects regulators of pressure are used. Following initial data are necessary for proper selection of a regulator and calculation of throughput: a working environment, entrance and target pressure, expense, temperature of a working environment, accuracy of regulation, a class of tightness, diameter of the pipeline, type of accession, constructional materials, external or internal registration of target pressure, protection against excess of pressure.The decision of this problem is closely connected with the proved choice of types of the process equipment, wide automation of technological processes, introduction of new technical decisions, use of necessary means of the control over realization of problems of complex mechanization of technological operations. In article the analysis of work of the functional module of a vertical multiline automatic packing machine on the basis of a proportional regulator of pressure «CAMOZZI» with realization of a feedback by means of an analog signal of regulator МХ-PRO [1-3] is lead. The drive of the holder for a rolled material has been tested on proportional management of position of the directing rollers used on a technological site of supply and regulation of a tension of a tape of a roll of a packing material at formation of packing.Results on use as the operating module of regulator МХ-PRO for management of a drive of the holder for a roll of a material in view of a course and pressure in a pneumatic system are received. Carried out researches provide the way to raise operational properties of a transportation system of supply of a packing material for technological processes of packing modules at the food enterprises.
Highlights
The vertical multiline automatic packing machines working from two rolls, are applied usually to fine packing for portions of loose, liquid, viscous and fine piece production in flat packages for the packing, produced of various thermal welded or thermal stuck together film materials, as well as the filtrational paper laminated by polythene of a paper and an aluminium foil
The model of system of positioning considered in the given work, allows to specify parameters of the functional module of a packing machine, and to change them by means of a feedback between a proportional regulator of pressure and the executive mechanism
At variation of expense of gas through a regulator, for example, an increase due to the consumer, pressure upon its output Pout will decrease, owing to what the balance of forces on a sensitive element of a regulator – the piston that will lead to an increase of the area of section of a throttle between the piston 6 and the piston of a rod 3 will be broken
Summary
In recent years the government pays great attention to new approaches to solve environmental and food problems. Scientists have suggested the technologies arranged for the protection of the health with the use of new elements of structure possessing both technological and physiological properties They have aptitude to form a proper structure of the food and remove from it agents which are not recommended by medical demands and maintain competition ability of a producer. The goal of the search is to optimize recipes for muffins according to the main indicators of chemical composition, to meet the needs of a particular group of consumers (under physiological nutrition standards for different groups). According to this goal optimality criterion has been defined. As an optimality criterion or objective function of the mathematical model we selected ratio of carbohydrates and proteins, which is set for a proper group of work intensity [4]
