当单位粒重获取单元数出的粒数达到设定的粒数值时, 数粒停止; 数粒 计量斗称出已数粒的物料重量; PLC计算单位粒重并根据设定的包装规格求 出包装重量, 写入包装秤的称重控制器;
包装秤开始称量;
在包装秤工作期间, 单位粒重获取单元连续不断的给出单位粒重, 修正 包装重量。
4、 根据权利要求 3所述的方法, 其特征在于: 在保证每次数粒的粒数能 充分代表正在包装物料的前提下, 每隔几十秒就可以调整一次包装重量。
5、 根据权利要求 3所述的方法, 其特征在于: 设定包装秤的包装规格和 单位粒重获取单元每次数粒的粒数时, 各种不同的情况下的操作方式如下: 当单位粒重获取单元设定的每次数粒粒数等于包装规格时, 每次数出的 粒数, 经包装秤的计量斗称重, 获取单位粒重后, 将物料排出到包装容器中; 单位粒重获取单元设定的每次数粒粒数小于包装规格时, 每次数出的粒 数, 经包装秤的计量斗称重, 获取单位粒重后, 缺少的粒数由包装秤的加料 装置补足后, 再将物料排出到包装容器中;
单位粒重获取单元设定的每次数粒粒数大于包装规格时, 单位粒重获取 单元将按包装的目标粒数的倍数, 分成几次数粒。 再将几次的结果累加起来, 计算单位粒重; 每次数粒粒数达到目标粒数时, 将其排入包装秤的计量斗进 行称重并记忆, 计量斗将物料排出到包装容器中; 最后一次的数粒粒数如果 小于包装的目标粒数, 缺少的粒数由包装秤的加料装置补足。
6、 根据权利要求 3所述的方法, 其特征在于: 所述的单位粒重的计算方 法是: 每次以小样本数粒, 采用移动平均或移动加权平均, 计算出单位粒重。
7、 根据权利要求 3所述的方法, 其特征在于: 所述的单位粒重的计算方 法是: 以单次的大样本数粒结果, 计算出单位粒重。
8、 根据权利要求 3所述的方法, 其特征在于: 所述的单位粒重的计算方 法是: 每次以大样本数粒, 采用移动平均或移动加权平均, 计算出单位粒重。
