基于建立的行李系统单条输送线处理能力数学模型,分析了行李输送过程中行李渐停等流量不平衡因素对行李系统处理能力的影响,提出了间距控制和间隙控制等两种流量控制的方法并论述了其控制原理,基于间距控制方法建立系统处理能力、运输物体特性及皮带运行速度等数学模型,设计缓冲输送机并进行系统输送能力模拟仿真,结果表明:该控制方法具备良好的缓冲能力,能有效提升系统稳定性和处理量。

In this paper,we first built a mathematical model of the handling capacity of a single conveyor line in a baggage transport system,analyzed the influence of unbalance factors such as slowdown of baggage movement in transit on the baggage handling capacity,proposed two flow control methods,namely spaced control and clearance-based control,and discussed their working principles.Then,based on the spaced control method,we built the mathematical models of the processing capacity,transport object characteristics and belt running velocity of the system,and designed a buffer conveyor to simulate the conveying capacity of the system.The result showed that this control method has good buffering ability and can effectively improve the stability and handling capacity of the system.
