可拆卸转椅的物流包装尺寸标准化及堆码研究

目的研究可拆卸转椅的物流包装尺寸标准化范围和堆码选择。方法以宜家可拆卸转椅为例．结合其具体的实际尺寸。按照平放、立放、侧放的放置方式，模数、组合及装柜软件的分割方法，分别进行堆码数目计算。最后对比总结规律。结果可拆卸转椅一般采用1200mm×1000mm的标准托盘。通常单个包装的范围为L500～1000mm，B400～700mm，H80—300mm。结论标准范围有5类．600mm〈L〈1000mm时．400mm〈B≤500mm，500mm〈B≤600mm，600mm〈B≤700mm；500mm〈L≤600mm时．400mm〈B≤500mm．500mm〈B≤600mm；堆码最优数目为模数分割和组合分割比较的最大值：600mm〈L〈1000mm时．以侧放堆码为主，堆码数目较多；500mm〈L≤600mm时，以立放堆码为主。堆码数目较多；稳定性以平放为主，立放次之，侧放最后。
