目前我国中小型型钢车间所生产的型钢(如角钢、槽钢和工字钢等),通常都是经过矫直后,被送到收集槽内,再经人工排列成束,打捆后吊车运走。因此工人劳动强度大,生产率低,包装质量差,而且在运输过程中经常发生松捆和散捆现象,以致产生扭曲变形,影响了产品使用率。据有关方面统计资料表明,由于捆扎质量差,不仅造成经济损失,而且影响我国产品在世界市场上的信誉和竞争能力。因此改善包装质量就显得更为迫切和重要了。 At present, the section steel (such as angle steel, channel steel and I-beam) produced by the small and medium-sized steel workshops in our country are usually straightened and then sent to the collecting trough, and then arranged in bundles manually, go. Therefore, workers are labor-intensive, have low productivity, and have poor packaging quality. In addition, loose bales and loose bales often occur during transportation, resulting in distortion and affecting product usage. Statistics from the relevant authorities show that the poor quality of the bundling not only causes economic losses but also affects the credibility and competitiveness of our products in the world market. Therefore, improving the quality of packaging becomes more urgent and important.
