31、hong, mechanical and electrical drive control M.Wuhan: Huazhong University of Science and Technology press, 20009型钢堆垛机是一种用于对成型钢材自动打捆的设备。机械部分由单传辊道、拨钢机构、移钢机构、分组机构、定位机构、平移机构、翻转机构和垛台升降及压紧机构等 8 个子机构，和 PLC控制部分组成的成型钢材自动打捆生产线。它的主要优点在于实现了整个生产线的自动控制，从而提高堆垛机的堆垛效率，这也是现今钢材堆垛打捆和以后发展的趋势。它不仅仅克服了过去人工堆垛的生产效率低、打捆质量差、成

32、本高、工作环境危险等缺点，更重要的是型钢的堆垛打捆成为了整个轧钢生产线发展的阻碍，在很大程度上阻碍了钢材生产线的效率的提高，对整个生产效率的提高有很大的影响。在一定程度上实现了自动化，很好的消除了这个障碍，对型钢生产线技术的进一步发展做了铺垫。型钢堆垛机能够实现自动堆垛打捆，对改善工人的劳动状况尤其是减轻工人的劳动强度、提高型钢的包装质量、提高轧钢生产线的生产效率、增强钢材市场的竞争能力、提高经济效益和社会效益创造了良好的条件。型钢堆垛机的制造成本较低，这对任何企业来说都是一个很重要的参考依据。目前，世界上堆垛机的发展已经很成熟了。已发展形成了各种类型的小型车间用的标准堆垛机主要有两大类，磁性

33、和非磁性堆垛机。一类是磁性堆垛机。轧件由装有可调磁性的翻转臂和输送小车进行一车堆垛，并且层与层之间是面对面或背对背交替放钢材堆垛后，由平立辊道输送到打捆区，平立辊道的宽度是可调的，以避免料垛散落。另一类是非磁性堆垛机。轧制由两套液压一机械机构控制的机械手进层层堆垛其动作类似于人手。可夹持并移送钢材，将钢材层面对面或背对背的进行堆放，主要适用于中小断面型钢，可避免料层中钢材在堆垛臂失磁时散落。形成不正确的料捆成形状非磁性堆垛机即纯机械堆垛机的显著特点就是无故障的处理双层型钢的能力，故其机械效率可提高一倍。传动机构通常分为机械传动、电器传动和流体传动。机械传动是最初的传动方式也是最重要的传动方式之一，它是在电动机等动力源的驱动下通过一定的机械式传动机构（齿轮机构、带传动和链传动等）得到期望的运动参数。流体传动是以流体为工作介质进行能量替换、传递和控制的传动。它包括液体传动和气体传动，液体传动是以液体为工作介质的流体传动，它包括液力传动和液压传动。 其中机电传动和液压传动是最常用的两类传动。电动机分为交流电动机和直流电动机两大类，交流电动机又分为交流电动机和直流电动机两类。在强电系统中三相交流异步电动机结构简单，运行可靠，成本低廉等优点，广泛应用于工农业生
