附图说明 附图组成本说明书的一部分, 用来帮助进一步理解本实用新型。 这些附 图图解了本实用新型的一些实施例, 并可与说明书一起用来说明本实用新型 的原理。 附图中: 图 1示出才艮据本发明的一个实施例的示意图; 图 2a示出根据本发明的一个实施例的局部视图, 图 2b示出沿线 A-A 截取的截面图; 图 3a至图 3f示出根据本发明的一个实施例的纸卷成型步骤顺序图; 图 4示出才艮据本发明的另一实施例的示意图; 图 5a和图 5b分别示出根据本发明另一实施例的装置的局部视图; 图 6a至图 6f示出才艮据本发明另一实施例的纸卷成型步骤顺序图。 具体实施方式 以下将参照本发明的优选实施例来描述本发明。 如图 1所示, 才艮据本发明的装置包括上部卷绕辊 (或第一卷绕辊) 1、 下部卷绕辊 (或第二卷绕辊) 3、 骑辊 (或第三卷绕辊) 2、 引导槽 5、 卷芯 导入单元 6、 供应辊 8、 以及粘结剂涂敷装置 (图 1未示出)。 根据本发明的 装置还包括 架 (未示出)。 其中, 上部卷绕 ¾ 1 和下部卷绕 ¾均可转动地 安装在该框架上。 本发明的上部卷绕辊 1、 下部卷绕辊 3以及骑辊 2与现有 技术相同, 在 it匕不再描述。 该上部卷绕 ¾ 1用于从供应 ¾ 8接收纸张 7b , 下部卷绕 ¾ 3以大约为 卷芯直径的 3巨离与上部卷绕 ¾间隔开。 上部卷绕 ¾ 1和下部卷绕辊 3可以如 图 1 箭头所示的方向旋转, 骑辊 2不仅自身可以转动而且可以相对于轴 21 转动。 预成型卷纸 7a 被容纳在上述三个辊形成的空间中, 随着卷芯上纸的 卷绕, 卷芯上纸张的直径增大, 骑辊 2 围绕轴 21 转动, 以便容纳增大的预 成型的卷筒纸。 才艮据本发明的卷芯导入单元 6 包括可转动地安装在上述 架上的按压 臂 61 , 其邻近上部卷绕辊设置, 并且位于引导槽 5的上游。 该按压臂 61的
一端设置有夹片 611 , 该夹片前端 (或顶端) 由诸如橡胶等摩擦材料制成, 从而在其与上部卷绕辊 1上传送的纸张接触时, 可以有效的按压纸张。 该卷 芯导入单元 6还设置有用于拾取并保持卷芯 (例如, 通过真空方式保持) 的 支撑件 (或支撑臂) 63 , 卷芯可以容纳在按压臂和支撑件之间 (如图 1所示 的卷芯 7 )„ 并且, 按压臂 61和支撑件 63可以整体围绕卷芯导入单元上 6的 轴 65转动, 该轴 65设置在上述的 架上。 引导槽 5围绕上部卷绕辊 1的一部分圓周间隔设置,用于将保持在卷芯 导入单元 6中的卷芯朝向上部、 下部卷绕辊 1、 3和骑辊 2形成的容纳空间 引导, 该引导槽 5设置于卷芯导入单元 6与下部卷绕辊 3之间, 并且以略小 于卷芯直径的 巨离与上部卷绕 ¾ 1间隔设置。 粘结剂涂敷装置设置在卷芯导入单元 6的上游,用于在将卷芯传送到卷 芯导入单元 6之前, 在卷芯上涂敷两条胶线。 该涂敷过程如图 2b所示, 卷 芯通过卷芯供应 昆 93 沿箭头方向朝向卷芯导入单元 6传送, 在朝向卷芯导 入单元 6的传送路径上设置有喷胶枪, 通过该喷胶枪的一对喷嘴 91对通过 卷芯供应 昆 93传送的卷芯涂敷两条胶线 GS ,该两条胶线平行于卷芯的轴线。 当然除了喷胶枪外, 还可以使用任何涂敷装置, 例如, 印刷辊。 图 2还示出了上部卷绕 ¾ 1、 卷芯导入单元 6、 机器的 架 10、 的平面 图以及沿线 A-A截取的截面图。如该截面图所示,卷芯 7上涂敷有两条胶线。 如图所示, 该上部卷绕 ¾ 1 包括粗糙区域 11和光滑区域 13 , 该两区域相互 交替设置。 如图 3a至 3f所示, 下面我们来描述如何通过该装置形成卷筒纸的。 如图 1所示, 经过虚切的纸张 7b (例如图 1所示的虚切部分 PI , P2, P3 ) 通过供应辊 8传送。 并且, 当卷芯通过卷芯传送辊 93朝向卷芯导入单 元 6传送时, 通过设置在卷芯导入单元 6的上游的喷胶枪上的一对喷嘴 91 , 沿该卷芯的轴线方向在卷芯上涂敷两条胶线 GS , 其中, 标号 71为粘附卷筒 纸最内层纸的胶线 (称为拾取胶线), 标号 73为用于封住卷筒纸最后一层纸 的胶线(称为封尾胶线)。 通常可以通过改变卷芯传送的速度、 或喷胶枪内的 压力或者改变喷嘴而 艮容易的调节所涂敷的粘结剂的量。 当然, 所涂敷的胶 线可以在任何合适的位置中断, 从而避免与将卷芯导入卷绕区域的卷芯 I导 单元 6相接触。
卷芯导入单元 6拾取和支撑涂敷有两条胶线 GS的卷芯, 并将其导入引 导槽 5 中。 如图 3e、 3f, 卷芯导入单元 6围绕轴 65转动, 并通过, 诸如, 真空装置,拾取涂敷有两条胶线 GS的卷芯 7并将其容纳在按压臂 61与支撑 件 63之间, 其中, 如图 3f所示放置涂敷有胶线 GS的卷芯 7。 卷芯导入单元 6继续转动, 使得卷芯 7位于引导槽 5的上游, 如图 3a所示。 当正在成型的卷纸筒 7a卷绕了预定长度的纸张时, 卷芯导入单元 6的 按压臂 61 和支撑件 63 围绕轴 65转动, 涂敷有胶线 GS的卷芯以及按压臂 61在传送纸张与上部卷绕昆 1相切的位置与该纸张接触(如图 3b所示)。 此 时, 上部卷绕辊 1继续转动, 而卷芯导入单元 6并未释放卷芯, 该卷芯上的 一条胶线 73粘附到正在卷绕成型的卷筒纸 7a预定长度的最后一页纸上,即, 图 3b所示的虚切 P2与 P1之间。 按压臂 61的夹片 611按压在上部卷绕辊 1 的摩擦相对较小的平滑区域 13。 由于该夹片 611按压在上部卷绕辊 1的光滑 区域 13上的纸张, 该纸张在该辊的粗糙区域 11上容易翘起, 而上部卷绕辊 1 仍然原速转动, 从而, 纸张在靠近夹片 611 的虚切位置 P1 处断开, 如图 3c所示。 正在成型的卷纸筒继续卷绕断开的纸张, 由于, 在虚切位置 P1 与 P2 之间粘附有粘结剂 (即其中一条胶线), 通过上部卷绕辊 1、 下部卷绕辊 3以 及骑辊 2的转动挤压, 使得纸张粘附卷绕在卷纸筒上, 从而进行了封边。 并 且, 下部卷绕辊 3的线速度相对于上部卷绕辊 1和骑辊 2降低, 从而使得成 型的卷筒纸 7a从该辊的表面离开, 掉落到工作台 4上。 同时, 卷芯导入单元 6转动, 将卷芯 7放到引导槽 5中, 如图 3d所示。 卷芯 7在上部卷绕辊 1的带动下沿着引导槽 5运动,由于其上涂敷有胶线 GS , 被切断的纸张, 即, 位于虚切部分 P1下游 (如图 3c所示的虚切部分 P1的 左侧) 的纸张, 粘附在卷芯 7上, 随着卷芯 7在引导槽 5的运动, 并且纸张 被不断卷绕在卷芯 7上。 随着上部卷绕昆 1的转动, 卷芯 7被传送到上部卷 绕辊 1、 下部卷绕辊 3以及骑辊 2之间的空间内, 在该空间内, 卷芯 7在该 三个 ¾的转动下卷绕纸张。 在卷芯 7卷绕纸张时, 卷芯导入单元 6拾取新的 卷芯准备进行卷纸成型。 根据本发明,通过将例如喷胶枪和印刷辊等粘结剂涂敷装置设置在卷芯 导入单元的上游, 在卷芯进行卷绕纸张之前, 在该卷芯上涂敷两条胶线, 从 而, 简化了流程, 并且节省了成本, 提高了效率。
图 4示出了根据本发明另一实施例的示意图。 与上述实施例不同的是, 才艮据本实施例的装置设置有与上部卷绕辊 1 的粗糙表面同心的固定指状件 15 , 该固定指状件 15 设置在支架上, 该支架可被固定或在进行打断时可移 动。 并且该固定指状件 15容纳在上部卷绕 ¾ 1 环形凹槽中, 该环形凹槽在 外圓周的光滑区域上沿圓周方向设置, 并且固定指状件 15 在环形凹槽内设 置成与上部卷绕辊 1隔开。 除此之外, 该实施例的其它设置与上述实施例相 同, 因 it匕, iH处省略相同部分的说明。 如图 5a和图 5b所示, 上部卷绕 ¾ 1在光滑区域处设置有环形凹槽。 该 凹槽两侧为上部卷绕辊的粗糙区域, 该粗糙用以提供足够的卷绕牵引力。 卷 芯导入单元 6的夹片 611在传送的纸张与上部卷绕 ¾相切位置附近, 将传送 的纸张按压在固定指状件 15上 (如图 4所示)。 图 6a到图 6f示出了设置有固定指状件 15的该装置的纸卷成型步骤顺 序图。 除了在传送的纸张与上部卷绕 ¾相切的位置附近, 卷芯导入单元 6的 夹片 611将传送的纸张按压在固定指状件 15上外,其它步骤与上述实施例相 同, 在 匕省略对其的详细描述。 根据该实施例的本装置, 由于设置了固定的指状件, 从而, 能够緩解当 卷芯导入单元的夹片将纸张按压在上部卷绕辊时, 由于它们之间的速度差异 产生的冲击。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本 领域的技术人员来说, 本发明可以有各种更改和变^^ 凡在本发明的 4青申和 原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的权利 要求范围之内。
