运动方程

The dissertation investigates the multilane-to-uniline problem in order to solve the theory problem and technique problem of feeding high speed palletizer with several production lines. The harmony equation of the problem is established with the method of movement tracing according to the thought of unit accumulation and free bumping of materials from different lines. For the random of unit materials forming, a strategy of key assignment is put forward to avoid the bump of materials from different lines.

为了解决采用多条供料线向高速码垛机供料以充分利用高速码垛机的处理能力的理论问题和技术问题，本文从一般的角度研究了多线合一问题，根据料股缓冲的思想和无供料干涉的原则，利用运动追踪的方法建立了多线合一问题的协调方程，由此建立了结构参数之间的相互制约关系，为结构参数的制定提供了理论依据，在随机供料的情况下，由于各线料股的形成具有随机性，为了避免各线之间的干涉，本文提出了一种钥匙分配策略很好地解决了这一问题。
