Description

在定量输出通道之前检测并剔除缺陷烟支的方法和装置 技术领域
本发明属于卷烟包装机械， 特别是涉及一种在定量输出通道之前检测并剔除缺陷 烟支的方法和装置。
背景技术
现有卷烟小包包装机的烟支定量排列整理箱包括以下主要结构： 连接烟支输送通 道的料斗、 料斗底部由两个分流块相隔形成的三个烟支分流槽、 分别衔接于各烟支分 流槽的三个烟支定量输出通道， 通常三个烟支定量输出通道按 7-6-7或 7-7-6烟支数 量设置下烟道， 烟支定量输出通道与间歇步进的模盒输送装置相衔接， 模盒输送装置 的后段设置烟支质量检测器。
上述小包包装机明显存在以下主要缺陷， 对于模盒中存在空头缺陷烟支的烟支组 采取整组剔除的处理方式， 既浪费了大量的包装材料和工时， 也大幅度降低了回收烟 丝的品质， 因此浪费巨大。
为解决上述技术问题，公开号 CN1545948的发明申请《一种烟支剔除方法和装置 》 公开了一种用于剔除缺陷烟支的方法， 包括： 在包装机下烟通道即烟支定量输出通道 上设置检测位置和剔除位置， 通过检测器在检测位置检测烟支； 每检测到一个有缺陷 的烟支单支， 都向一控制器发送一缺陷信号； 控制器计算缺陷烟支到达剔除位置的时 亥 |J， 并在该时刻发送剔除信号给剔除执行器； 剔除执行器在剔除位置剔除缺陷信号对 应的缺陷烟支。 其装置包括检测器、 控制器和剔除执行器； 检测器和剔除执行器安装 于下烟通道上， 检测器检测到缺陷烟支后， 发送缺陷信号给控制器， 控制器发送剔除 信号给剔除执行器， 剔除执行器剔除缺陷烟支。
上述发明申请是在下烟通道采取单支烟支检测并剔除的方法， 由于剔除过程将造 成烟支流的中断， 因此不能避免因剔除使模盒中出现缺支的现象。
发明内容
本发明的目的是公开一种在定量输出通道之前检测并剔除缺陷烟支的方法和装 置， 所述方法和装置首先克服了在模盒中检测缺陷烟支并整组剔除存在的巨大浪费现 象， 也克服了在烟支定量输出通道设置检测和剔除位带来的缺支现象。
本发明为实现上述目的的方法是： 在各烟支分流槽的输出口分别衔接烟支检测通 道， 各烟支检测通道使烟支排列成为相互平行的垂直烟支流， 垂直烟支流的数量与所 对应的烟支定量输出通道的下烟道数量相等， 各垂直烟支流的流道中均设置烟支质量 检测器和气动剔除机构， 被检测的烟支是在合适的停顿时间内完成检测和剔除， 检测 合格的烟支经由逐支横向推移机构直接进入相应的烟支定量输出通道的相应下烟道。
所述各垂直烟支流的逐支横向推移机构同步动作， 任一垂直烟支流的气动剔除机 构动作或连续动作时，各垂直烟支流的逐支横向推移机构均延迟相应的横向推移周期。
本发明的装置包括料斗、 料斗底部的三个烟支分流槽、 三个烟支定量输出通道、 烟支质量检测器、 计数剔除控制器和气动剔除机构， 特征是， 各烟支分流槽与所对应 的烟支定量输出通道之间分别设有烟支检测通道， 所述各烟支检测通道设有由平行且 均布的隔板构成的各烟支检测流道， 各烟支检测通道的烟支检测流道的数量与所对应 的烟支定量输出通道的下烟道数量相等， 所述各烟支检测流道的一侧隔板与所对应的 下烟道上端口上下位置重合或部分重合， 所述各烟支检测流道的后侧板分别设有一烟 支质量检测器和位于该检测器下方的烟支剔除口， 所述各烟支检测流道的底端口分别 设有由横向移动的推板和固定的托板构成的逐支横向推移机构， 所述推板位于烟支检 测流道另一侧隔板的底面， 横向移动的推板封堵该烟支检测流道底端口， 三个烟支检 测通道的所有推板均连接于一横向往复运动的传动杆， 所述托板位于下烟道上端口对 应推板的一侧， 下烟道该侧侧边与对应的托板侧边上下重合， 托板表面与烟支检测流 道底端口的距离等于烟支直径。
所述一烟支检测通道的各推板之间的距离等于烟支直径。
所述托板落烟侧的侧边设有导烟斜面。
本发明的有益效果和优点在于： 本发明的经烟支检测通道的各烟支检测流道将烟 支排列为与烟支定量输出通道的各下烟道数量对应的烟支流， 为在烟支定量输出通道 之前逐支进行质量检验提供了基础条件。 本发明的各烟支流分别由其托板支撑， 能够 为逐支进行质量检验或剔除提供必需的停顿时间。 本发明的与各托板分别组合构成烟 支逐支横向推移机构的推板其横移时间与卷烟包装***运行速度相匹配， 横移区间以 封堵烟支流并将直接支撑于托板的无缺陷一烟支推离托板为准。 由于被推离托板的无 缺陷烟支其运动方向无障碍， 并依靠其自重落入下烟道， 因此经检测的烟支横向移动 和下行是在轻柔的过程中完成的， 对烟支无损伤。 本发明的横向往复运动传动杆可以 采用成熟的现有技术予以驱动， 如凸轮连杆机构、 气动或液压机构等。 本发明的烟支 质量检测器、 计数剔除控制器和气动剔除机构均采用成熟的现有技术， 能够准确实现 缺陷烟支的剔除。 经实验证明， 本发明的样机在每分钟 400包包装速度下对人为设定 的空头 （烟丝不饱满） 缺陷烟支的检测和剔除率达到 100%。 总之， 本发明使得有质量 问题的烟支在未进入烟支定量输出通道之前被剔除， 从而彻底避免了整组剔除烟支组 造成的巨大浪费。 经实验还可以证明， 对于缺少滤嘴缺的陷烟支在烟支检测流道中其 一端相对于烟支质量检测器的距离具有随机性， 烟支质量检测器同样将其视为空头缺 陷烟支予以识别。

具体实施方式
下面结合实施例及其附图进一步说明本发明。
如图 1、 2所示实施例 1， 本烟支整理箱包括现有料斗 2、 由分流块 3分隔出的三 个烟支分流槽 4和三个烟支定量输出通道 8， 料斗 2连接烟支输送通道 1。三个烟支定 量输出通道 8的下烟道 8-1数量分别按 7-6-7烟支数量设置。
各烟支分流槽 4与所对应的烟支定量输出通道 8之间分别设有烟支检测通道 5， 各烟支检测通道 5设有由平行且均布的隔板 5-2构成的各烟支检测流道 5-1。 各烟支 检测通道 5的烟支检测流道 5-1的数量与所对应的烟支定量输出通道 8的下烟道 8-1 数量相等。
图示各烟支检测流道 5- 1的右侧隔板与所对应的下烟道 8-1上端口上下位置部分 重合， 各烟支检测流道的后侧板 13分别设有一烟支质量检测器 10和位于该检测器下 方的烟支剔除口 9， 本实施例的烟支质量检测器与烟支剔除口的轴心距为两倍烟支直 径。 图 1中， 各烟支检测流道 5- 1的底端口均设有由横向移动的推板 6和固定的托板 7构成的逐支横向推移机构， 推板 6位于图示烟支检测流道另一侧即左侧隔板的底面， 横向移动的推板 6封堵该烟支检测流道底端口。 一烟支检测通道 5的各推板 6之间的 距离等于烟支直径， 该距离便于托板 7支撑的检测后烟支的定位。
图 1中， 三个烟支检测通道 5的所有推板 6均连接于图 2所示的一横向往复运动 的传动杆 1 1。 本实施例的传动杆 1 1连接于凸轮连杆机构， 其动力源采用伺服电机。
如图 1所示， 托板 7位于下烟道 8- 1上端口对应推板 6的一侧， 下烟道该侧侧边 与对应的托板侧边上下重合， 托板 7表面与烟支检测流道底 5- 1端口的距离等于烟支 直径。
下面结合图 3、 4简要说明图 1实施例 1的烟支检测和剔除过程。
如图 3所示， 推板 6位于烟支检测流道各隔板 5-2的底面， 此时各烟支检测流道 的烟支流 15在托板 7作用下为停顿状态， 该状态下进行烟支检测或剔除动作。剔除动 作是烟支质量检测器 10发出缺陷烟支信号给 PLC , PLC令伺服电机停止转动并使推板 6位于烟支检测流道各隔板 5-2 的底面、 同时启动计数剔除控制器， 计数时间等于缺 陷烟支从检测位下落至烟支剔除口的时间。 计数时间到， PLC 发出剔除指令启动气动 剔除机构， 图 2中的气流喷嘴 12喷射的气流使缺陷烟支从烟支剔除口 9射出。与此同 时 PLC还发出检测指令， 使暂时停留在检测位的烟支及时受检。 如果烟支质量检测器 10发出连续缺陷烟支信号给 PLC , 说明烟支流 15中出现连续的例如两只缺陷烟支， 此 时 PLC令伺服电机停止转动并使推板 6位于烟支检测流道各隔板 5-2的底面的同时将 连续两次启动计数剔除控制器， 每次均包括剔除指令。
如图 4所示， 当烟支质量检测器未检出缺陷烟支时， 各推板 6在传动杆带动下按 图 4箭头 a所示方向横移至封堵烟支检测流道位置， 与此同时将直接支撑于托板的无 缺陷一烟支推离托板并按图 4箭头 b所示方向依靠其自重落入下烟道 8- 1。 从图 3、 4 可以看出本发明实现了在定量输出通道之前检测并剔除缺陷烟支的目的。
如图 5所示实施例 2， 本实施例的包括烟支输送通道 1、 料斗 2、 分流块 3、 烟支 分流槽 4、三个烟支定量输出通道 8以及下烟道 8- 1数量的烟支整理箱基本结构与图 1 实施例 1相同。 同时， 与实施例 1一样， 各烟支分流槽 4与所对应的烟支定量输出通 道 8之间分别设有烟支检测通道 5， 各烟支检测通道 5设有由平行且均布的隔板 5-2 构成的各烟支检测流道 5- 1。 各烟支检测通道 5的烟支检测流道 5- 1 的数量与所对应 的烟支定量输出通道 8的下烟道 8- 1数量相等。 本实施例 2与实施例 1的区别在于， 烟支检测流道 5-1的右侧隔板与所对应的下 烟道 8-1上端口上下位置相重合，各烟支检测流道设置的烟支质量检测器 10和烟支剔 除口 9以及两者的轴心距与实施例 1相同。
如图 5、 6、 7所示， 各烟支检测流道 5-1的底端口均设有由横向移动的推板 6和 固定的托板 7构成的逐支横向推移机构， 推板 6位于图示烟支检测流道左侧隔板的底 面， 横向移动的推板 6封堵该烟支检测流道底端口。 一烟支检测通道 5的各推板 6之 间的距离等于烟支直径， 该距离便于托板 7支撑的检测后烟支的定位。
图 5中， 三个烟支检测通道 5的所有推板 6与实施例 1一样均连接于一横向往复 运动的传动杆。
如图 5、 6、 7所示， 托板 7位于下烟道 8-1上端口对应推板 6的一侧， 下烟道该 侧侧边与对应的托板侧边上下重合， 托板的落烟侧的侧边设有导烟斜面 7-1， 托板 Ί 表面与烟支检测流道底 5-1端口的距离等于烟支直径。
实施例 2的烟支检测和剔除过程与实施例 1相同， 但由于烟支检测流道 5-1的右 侧隔板与所对应的下烟道 8-1上端口上下位置相重合， 因此推板 6横移范围要大于实 施例 1。 当推板 6按图 7箭头 a方向横移时， 直接支撑于托板 7的无缺陷烟支将沿托 板的落烟侧侧边的导烟斜面 7-1按图 7箭头 b所示方向依靠其自重落入下烟道 8-1。
