Embodiment Construction
[0034] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0035] An embodiment of a sub-packaging production method of a multi-variety and small-batch mixed-flow assembly line:
[0036] In tractor mixed-flow assembly production, the optimization goal of sub-assembly production is to meet the needs of final assembly on time and quantity. Tractor sub-assembly production includes the assembly of key components such as engine, transmission system, braking system, cab, etc. The present invention is based on the manufacturing execution system MES (Manufacturing Execution Syetem), using BS (Bubble Sort) automatic sorting algorithm, through computer programming to design the automatic sorting heuristic algorithm (Final assembly-automatic sequencing heuristic algorithm, FA-ASHA) of mixed-flow assembly production to realize the lean and informatization of tractor mixed-flow assembly production planning and automat...

The invention provides a subpackage production method and device for a multi-variety small-batch mixed flow assembly line, and the method comprises the steps: firstly setting a production sequence that an assembly produces various types of products, meeting the assembly demands of the assembly on time in a manner of accurate quantity according to the production sequence, and building a subpackage production target function; secondly calculating the subpackage start time Tsj according to the lead time Tj of each subpackage line and the assembly start time T0, wherein Tsj=T0-Tj; finally calculating the daily output of subpackaged parts according to the subpackage start time Tsj, the lead time Tj of subpackage, the assembly sequence requirement and machine configuration information, enabling the subpackage production of tractors to be ordered, guaranteeing that the assembly demands are met on time in a way of accurate quantity, shortening the production cycle, and improving assembly production efficiency.
Description
technical field [0001] The invention belongs to the field of mixed-flow assembly production of tractors, and in particular relates to a sub-package production method and device of a multi-variety and small-batch mixed-flow assembly line. Background technique [0002] Tractor is a kind of non-road working machinery under complex working conditions. Tractor is a typical product of agricultural machinery equipment, and its advanced production technology is directly related to the international competitiveness of my country's agricultural machinery and even agricultural products. Tractor mixed-flow assembly production is to meet the individual needs of customers. Products with similar assembly processes but different models are assembled on one production line to achieve low-cost, high-quality and high-efficiency flexible production methods, usually including Parts sub-assembly and product assembly are two-stage production. Among them, the sub-assembly production of tractors i...
