Embodiment Construction

[0048] see figure 1 , through the daily operation plan to obtain all the parts information required for the day's production, and use the real-time material distribution method to calculate and obtain the daily distribution result set, and the warehousing and distribution department will distribute the materials required for production to the production line in a timely manner and in small batches according to the distribution list. At the same time, the MES system monitors the production line in real time, regularly judges whether the next batch of materials to be delivered is reasonable according to the actual production situation, and adjusts the delivery plan in time. In addition, if the production plan changes, the distribution plan will also change.

[0049] see figure 2 , the specific algorithm structure is as follows: use the product BOM model to calculate the parts information required by each station for production on the day, and comprehensively consider the start...

Abstract

The invention discloses a real-time material distribution method in a mechanical product assembling process, which is characterized in that: according to the production plan on the same day, calculating to obtain all required parts; by considering the storage capability, the existing amount, the material lead time and the product cycle time of each part on each station, calculating a material distribution scheme; distributing the parts in time on small batches according to the obtained distribution scheme; simultaneously, tracking the on-site production situation by an MES system in real time; recording manufacturing product situation and the material consumption situation of each station; and timely feeding back production plan information and station inventory information. The method of the invention can realize on-time material distribution, feeds back and adjusts the distribution scheme in time according to real-time working condition, can improve production efficiency and lowers product cost.

Description

technical field [0001] The invention relates to the field of automation control, in particular to the field of mechanical product assembly, and specifically relates to a real-time material distribution method in the mechanical product assembly process. Background technique [0002] Under the Just In Time (JIT) mode of production, most of the existing material distribution methods are on-site pulling, that is, when a certain station is short of materials on site, a delivery reminder is given by a kanban or a material pulling system; Or set a safety stock. Whenever the consumption of materials reaches the safety stock, the workshop staff will send a reminder signal to the warehousing department, and then the warehousing department will arrange delivery workers to deliver. This passive distribution mode has a complex way of handling material pull and slow response speed, which is likely to cause material shortage or accumulation, affect production progress, lead to confusion in...
