Embodiment Construction

[0020] Now take the hot rolling production line as an example to further illustrate the present invention.

[0021] Such as figure 1 Shown: rhythm control method of the present invention comprises the steps:

[0022] 1. The operation mode of the material provided by the production line setting calculation module to the system, namely: the speed, acceleration and other parameters in each process;

[0023] 2. The material movement calculation module of this system calculates the flow time of each process in combination with the parameters provided by the setting calculation module;

[0024] 3. The rhythm calculation module determines the bottleneck point and rhythm time according to the operation diagram of the front and rear materials, and sends the time to the previous process and screen display;

[0025] 4. When the material is moving on the production line, the data acquisition module provides the determined time of the material in this system at each point on the producti...

Abstract

This invention provides a streamline process rhythm control method, which comprises the following steps: a, streamline design computation module providing the system material operation mode; the materials moving and computation module with the design module providing the flow time to each program; the rhythm computation module determining the neck point and rhythm according to material operation pattern; the data collection module providing the each point determined time to the self-adapting module and rhythm correction module; the self-adapting module providing the time difference value to the next material operation computation.

Description

technical field [0001] The invention relates to a production scheduling control method of a flow-type production line, in particular to a production line rhythm control method. Background technique [0002] Process-type production line rhythm control method is generally used in continuous production-type factories such as hot-rolling steel mills, steel pipe and bar factories, etc. It can coordinate the entire production stably and safely, and plays a very important role in increasing production output and coordinating the orderly operation of the entire production role. [0003] Most of the existing rhythm control methods are customized according to specific production processes and objects. Once the production equipment or production process changes, the corresponding rhythm control methods must be changed accordingly, and their reusability is poor. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a production l...
