本发明的实施方式
[0034] 本专利包装机的自动换模具装置具有相同的两套， 第一套自动换模具装置用于 换封合 （热合） 模并位于包装机的后部， 第二套自动换模具装置用于换成型 （ 吸塑） 模并位于包装机的前部， 所述前部和后部是相对于包装机的产品移动方 向而言的， 产品移动方向如图 1中的箭头所示。
[0035] 实施例 1 :
[0036] 所述的模具组设有四个模具， 分别是第一模具 9、 第二模具 10、 第三模具 11、 第四模具 12， 第一模具 9、 第二模具 10、 第三模具 11、 第四模具 12分别径向均匀 安装在模具安装架 8上， 相邻的两个模具之间径向相差 90度。 预先将四个模具的 位置编号输入电气控制系统 4内储存； 当更换包装物料吋， 将对应的模具编号告 知电气控制系统 4， 电气控制系统 4自动寻找该模具的位置， 并发出指令给数控 分度驱动机构 13进行分度旋转， 带动分度轴 7和模具安装架 8将所对应的模具转 至工作位 （朝上） 并锁住； 从而完成了自动换模的工作， 模具升降机构 5带动模 具支架 6和模具等运动完成包装工作 （参见图 7) 。 该自动换模具装置在包装机 生产线上的成型部分和封合部分同理通用。
[0037] 实施例 2:
[0038] 参见图 8， 本实施例与实施例的区别点仅为模具组为三个模具， 三个模具径向 均匀安装在模具安装架 8上， 此吋可以减小包装机高度， 减小回转空间， 其余设 计与实施例 1完全相同。
[0039] 本专利还可以将模具组设计为分别具有五个或六个模具， 工作原理同上。 本专 利模具组为一个模具库， 可根据需要随吋调用其中的一套模具。
[0040] 本专利通过模具升降机构 5驱动模具支架 6上下移动， 模具组具有多个模具， 每 个模具径向均匀安装在模具安装架 8上， 最上面的那个模具处于工作位， 其他模 具处于循环等待位置。 向上吋合模， 此吋工作位的模具幵始工作； 向下吋脱模 ， 此吋工作位的那个模具完成工作幵始脱离， 周而复始直至停机或达到了该产 品包装数量。 当需换模具吋， 由数控分度驱动机构 13驱动分度轴 7旋转， 将对应 的模具旋至工作位进行下一品种的产品包装， 原工作位的模具转到等待位置。 由于模具安装架 8上安装有若干个模具， 使得本实施例可以任意选择其中的一种 模具。 当需要换一种模具吋， 只需要通过数控分度驱动机构 13驱动分度轴 7将对 应的模具旋转至工作位即可， 节约了换模具的人力和吋间。
[0041] 本专利在原包装机基础上进行改进， 使其更智能化， 结构简洁可靠稳当。 凡是 上述构造、 特征及原理所做的等效或简单变化， 将落入本专利的保护范畴。
