Peculiarities of organization of aggregate-group flow

The tabulation of the LABOUR FORCE AND EQUIPMENT 

Summary tables of labour force and equipment are the same forms that were given in the calculation odnorotornyj flows. For the sectional flows sequential run, these tables are separately for each model, for the sectional flows with the cyclical start - one summary table of number of workers.

In the calculation of technical and economic parameters for flows with cyclical starting of the products is determined average consumption wage per unit of product at a price that calculates by multiplying the daily rate of the first category in the amount of the tariff coefficients and dividing this product for release of flow in change. 

The amount of wages at the rates individual models of products in mnogofotonnykh flows is determined by dividing the time of manufacture this product model by the average processing time and multiplying by the average consumption wage per unit of product.

Peculiarities of ORGANIZATION of AGGREGATE-GROUP FLOW 

Aggregate-flow group (synchromatic) is one of the organizational forms of production lines and mainly used for streams of high power. 

Conditions of organization of aggregate-group flow the following. 

1. The selection of the manufacturing processes of each part of the product independent technological group or area.

The calculation flow is performed in accordance with standard conditions of approval for mass production, moreover, is calculated for each technological group or section for processing individual components that should be subject to the uniform measure. The coefficients of permissible deviations from the tact taken to be +-10%. Technical and economic indicators are defined in the whole flow and each process group, or phase.

2. An arbitrary location in the stream of jobs each technological group or phase in a mandatory reduction of the maximum path of movement of semifinished products and the creation of facilities performing each work major and the commutative methods. 

3. Parallel fabrication of all components and their simultaneous arrival on installation site. 

4. Application packaway (batch) system running in the flow and transfer from site to site.

End-to-end flow (factory flow) is a kind of group flow and is characterized as a system of interrelated production lines of production throughout the manufacturing process one type of product. Therefore, an aggregate-group flow is comprised of several groups of workers or sections: rolling the billet parts (collar, front, back, sleeves, etc.), installation and finish of the product. The stream is divided into groups with respect between strict contingency work.

In such flows indivisible operations are completed in the organizational taking into account the technological feasibility of combinations of operations, the possibility of a more rational use of equipment and specialty workers, and not according to a predetermined cycle. The average settlement cycle, the number of workers and rate of flow set after the most successful acquisition transactions. 

The separation of stream processing nodes has a great advantage, as it allows simultaneously (in parallel) to perform a significant number of nodes and operations, thereby reducing cycle time.

When calculating the stream provide the most complete use of performance machines, high specialization of works for each workplace and the maximum reduction of time for the performance of auxiliary techniques. 

The layout and flow of individual jobs performed, taking into account the continuity and uniformity of motion of the parts and the principle of straightness (Fig. 134). It is necessary that the working areas directly adjacent to each other and the performers engaged in the processing of individual parts and components, took them from the workplace the previous operation.

In the organization of aggregate-group flow for the transfer of semi-finished product from one business location to another provided 
various production equipment: single and dvupolnye racks, flat majuscula various sizes, stingrays, sliding brackets, chutes, etc.

The organization is run in the following thread. In accordance with the schedule of bundles cut comes to the place of disassembly and storage (table prepare parts for run). Sausalito procurement section brings (brings up) fit to jobs, workers, and komplektatsia assembles machined parts. When using the conveyor the bundles are sent to cut jobs, and machined parts are served to the table running along the conveyor. In both cases, after processing the details of the packs comes picking, where they are subject to control and are sent to the mounting section.

The workplace of komplektatsii set trenbolone racks for storage of parts before and after picking. 

Picked items as needed serves on appropriate jobs the mounting section. Then the manufactured products are passed to the finishing section to employees of TCI and on the packaging.

This organization of threads reduces the need for special equipment due to the high rate of its use, allows to produce a variety of models without restructuring and losses, enhances agility performance when absenteeism of workers, increase the labor productivity through better use of individual abilities working.

In Fig. 135 given the layout of the shop of the Magnitogorsk garment factories with an aggregate-group flow for the manufacture of coats for boys, designed TSNIISHP. 

The technological process is performed in three sections: the procurement, installation and finishing. 

The blank section is organized in seven groups of jobs on the processing of the following components: procurement of shelves, backs, linings, collars, podborov, sleeveless and side strip. The launch of this section pachkovo. 

The installation of the product is carried out on two double-row belt conveyor systems.

Installed products come to the finishing section. 

In all the sections starting models in the flow consistent. 

The introduction of this stream gave the factory the option to increase the annual production of coat is 26%.
