FEATURES of the CALCULATION MNOGOSERIJNYJ AND MNOGOFOTONNYKH SECTIONAL FLOW 

IN high demand for garments of various types and models, and the need in this regard ensure the delivery of selling organizations products a wide range odnofaznye flows are unprofitable. Frequent refilling cause a significant loss of working time, and hence the decrease in productivity and deterioration in quality.

It is established that in the manufacture of uniform garments are technologically similar operations accounted for 80%, due to the appearance and design features of the product model. Coincidence processing a variety of garments provides the ability to group homogeneous technologically indivisible operations and to perform them to allocate jobs in a separate, specialized sections. This principle became the basis of the developed calculation method CNIISHP mnogoserijnyj, mnogofotonnykh sectional flows. 

The principle of organization mnogostoronnego mnogorazovogo sectional flow


 Mnogobashenniye flows provide the output of products of several kinds due to the sequential or cyclic start models into the cells of the conveyor. 

 Mnogobashenniye threads allow one thread during a given shift to produce products of the same species, but several styles. 

 Breakout flows are characterized by the fact that in them the process of manufacturing the product is divided into several separate production areas, or sections, specialized on the processing of individual parts and components of products.

Schematic diagram of the organization mnogorazovogo three-piece flow is that the product is made of three separate sections: the first performing the procurement of parts and individual components associated with raznovydnostey on the second Assembly of parts and components of products; on the third, final stage - finishing and acceptance of finished products. 

In the preparation of production and calculation odnorotornyj and mnogofotonnykh threads -there is a lot in common. Stages of the calculation mnogorazovogo flow are:

determining the number of models for the simultaneous production flow with a given substitution models, selection of the starting products into the stream; 

selection of models to run for 2 - 3 models in the group (on the same constructive basis) and prepare them for launch; the choice of methods of processing of products;

preparation of technological sequence of processing of products; 

a preliminary calculation of the stream; the division of the flow into sections; the calculation of the number of workers in each section; 

coordination of organizational operations, and analysis coordination of the operations of the flow; 

preparation of process flow diagram;

the tabulation of the labour force and equipment; 

planning flow; 

process design of the conveyor. 

Different types of garments that can be simultaneously manufactured in a single thread, specify the following main features: group of fabrics (Drapes, suiting wool, silk, etc.), the uniformity of the applied fixtures and equipment, the similarity of technological processing of parts and components products. 

The following is the distribution of the main types of garments homogeneous groups, whose manufacture is possible in one thread.

Form of organization of production flows depend on the level of mechanization of production of goods, performance of machines and devices. With increasing power flows, increased utilization of equipment. Experience of advanced garment factories showed significant benefits mnogofotonnykh sectional flows with rational power before streams of other types.

Such flows depending on the power and range of manufactured products may consist of two to four sections. Each section, consisting of one or more lines may have a different form of organization of the flow (aggregate-group, conveyor, non-conveyor and small series). 

The construction of production lines of the first section should provide for the movement of workpieces to the Assembly flow in the prescribed rhythm and the shortest path.

In the first section, in the manufacture of clothing, tend to produce the initial processing of details (pockets, collars, sleeves, lining, side strip), connecting the side strips with shelves, handling various relief lines on the shelves and the back coat, etc.; in the manufacture of women's dresses - processing of sleeves, collars, bodice, and belt; in the manufacture of men's shirts - treatment of collars, cuffs, sleeves.

Second, the Assembly, the sections treated with the sides of the shelves, connect the back with shelves, stachivaya sleeves; in the manufacture of women's dresses connect the bodice to the skirt, treated with a filler, stachivaya sleeves; in the manufacture of men's shirts work the clasp of the front, connect the collar and sleeves.
 

 
On the third section to produce a wet-heat treatment products and finishing work. 

If production flows are made up of four sections, the first manufacture individual parts and assemblies, the second performs the initial processing of main parts (shelves, backs, sides), the third builds of the product details on the fourth and final wet-heat processing and finishing of products.

In streams consisting of two sections, the first machining small parts, and the second carry out installation and finishing work.

In process streams with two and three sections each section can have a number of production lines or groups of jobs. 

In the manufacture of women's easy dresses first, second and third sections can be placed on separate lines or all three - on one, but each section should be separated into an independent group on technological grounds.
