Description

真空分选系统及出瓶装置
【技术领域】
本发明主要涉及到容器类物料的分选设备领域, 特指一种主要适用于瓶类容器分类传送 的真空分选系统及出瓶装置。
【背景技术】
目前, 在医药、 食品等包装设备领域中, 引入了实时检测部件, 用来区分灌装前或灌装 后容器的好、 坏状态; 经过实时检测部件的分析、 判断、 筛选后, 再通过分选部件将好瓶和 坏瓶分开, 利用各自独立的好瓶输送部件、 坏瓶输送部件将其分别输出。 例如, 在之前申请 CN201020276998. 5所公开的出瓶机构中, 就是通过安装于真空泵管路上的电磁阀的通断来控 制瓶体是进入出瓶拨轮还是剔瓶拨轮。
但是, 上述分选部件的结构形式存在以下不足:
1. 分选部件往往采用真空泵、 或其他类型的泵, 噪音十分大, 造成生产的环境较差;
2. 采用上述真空控制方式, 即使在连接电磁阀的前端管路装入过滤器, 也会因较小的渣 屑进入电磁阀而损坏阀芯, 进而降低真空分选的质量, 也缩短了分选设备的在线工作时长和 整体使用寿命。 渣屑还会掉落在真空泵与真空吸附口之间的管路上, 久而久之, 就会影响到 真空负压产生的效果;
3. 分选部件在使用时, 往往是对称布置, 即好瓶输送部件、 坏瓶输送部件呈相对设置, 好瓶通过分选部件进入好瓶输送部件, 坏瓶通过分选部件进入坏瓶输送部件中, 但是输瓶设 备在高速运转时, 往往靠真空吸附也不能保证万无一失的实现瓶体的分选进入, 从而始终无 法提高输瓶装置自身的生产效率。
【发明内容】
本发明要解决的技术问题就在于: 针对现有技术存在的技术问题, 本发明提供一种结构 更加简单紧凑、 能够降低工作噪声、 传送效率更高、 更利于分选控制的真空分选系统及出瓶 装置。
为解决上述技术问题, 本发明采用以下技术方案:
一种真空分选系统, 包括至少一组真空分选组件, 每组所述真空分选组件包括至少一个 真空发生器和至少一个真空用压缩气源, 所述真空发生器上的真空负压端通过气管与真空吸 附口连通, 所述真空用压缩气源供给压缩气体至真空发生器的进气端以在气管中产生真空。
作为本发明真空分选系统的进一步改进: 所述真空用压缩气源与真空发生器之间通过真空控制阀以控制压缩气体的通断。
本发明还包括一反吹用压缩气源, 所述反吹用压缩气源与真空发生器和 /或气管相连通, 所述反吹用压缩气源通过反吹控制阀控制压缩气体的通断。
所述真空发生器和气管安装于阀岛上, 所述阀岛上开设有用来与真空用压缩气源相连通 的真空用压缩气体入口、 用来与反吹用压缩气源相连通的反吹用压缩气体入口。
所述真空发生器的阀芯置于阀岛内, 所述真空用压缩气体入口通过阀岛与阀芯连通, 所 述反吹用压缩气体入口通过阀岛连通于阀芯与气管之间。
所述气管通过快装接头连接于阀岛上。
所述真空发生器上安装有消声器。
本发明进一步提供一种出瓶装置, 包括好瓶输送部件、 坏瓶输送部件、 控制部件以及真 空分选系统; 所述真空分选系统包括两组真空分选组件, 所述两组真空分选组件中的一个与 好瓶输送部件对应配合, 另一个与坏瓶输送部件对应; 每组所述真空分选组件包括至少一个 真空发生器、 至少一个真空用压缩气源以及至少一个反吹用压缩气源, 所述真空发生器上的 真空负压端通过气管与真空吸附口连通, 所述真空用压缩气源供给压缩气体至真空发生器的 进气端以在气管中产生真空, 所述真空用压缩气源与真空发生器之间通过真空控制阀控制压 缩气体的通断; 所述反吹用压缩气源与真空发生器和 /或气管相连通, 所述反吹用压缩气源通 过反吹控制阀控制压缩气体的通断。
作为本发明出瓶装置的进一步改进: 通过控制部件的控制, 当所述好瓶输送部件中的真 空分选组件处于真空吸附作业状态时, 所述坏瓶输送部件中的真空分选组件处于反吹作业状 态; 当所述好瓶输送部件中的真空分选组件处于反吹作业状态时, 所述坏瓶输送部件中的真 空分选组件处于真空吸附作业状。
所述真空控制阀和反吹控制阀均为常闭电磁控制阀, 在无瓶输入时真空分选组件处于非 工作状态。
与现有技术相比, 本发明的优点在于:
1、 本发明的真空分选系统及出瓶装置, 结构更加简单紧凑, 通过采用多级真空发生器, 从而避免了真空泵或其他类型气泵所产生的噪声污染, 能耗也将大大降低。 由于真空发生器 采用的是清洁干燥的正压压缩空气, 即使存在较小的渣屑进入真空发生器的阀芯, 也会被从 真空发生器的出气口吹出, 而不会损坏阀芯, 且真空控制阀均只控制正压的清洁干燥的压缩 空气进入, 因此都不会有任何玻屑等异物进入阀门而造成堵塞、 磨损等不良情况。
2、 本发明的真空分选系统及出瓶装置, 通过增设反吹功能, 增强了吸瓶的有效性, 降低 了对单路气道的真空度和气流量要求, 同时还能清理挂在气管入口的玻璃碎片等, 进而延长 了分选设备的在线有效工作时长和整体使用寿命。
3、 本发明的出瓶装置, 利用独特的真空分选系统, 使整个控制方式得以优化, 可控性更 强, 还可大大节约气源。 通过控制部件的控制, 当好瓶输送部件中的真空分选组件处于真空 吸附作业状态时, 坏瓶输送部件中的真空分选组件处于反吹作业状态; 当好瓶输送部件中的 真空分选组件处于反吹作业状态时, 坏瓶输送部件中的真空分选组件处于真空吸附作业状。 这样交替运行, 能够通过反吹将瓶体吹向相对布置的另一个输送部件中, 保证瓶体分选进入 的可靠性, 最终为提高整体输瓶速度提供了有力保证。

【具体实施方式】
以下将结合说明书附图和具体实施例对本发明做进一步详细说明。
如图 1和图 2所示, 本发明的真空分选系统, 包括至少一组真空分选组件, 每组真空分 选组件包括至少一个真空发生器 4和至少一个真空用压缩气源 15,真空发生器 4包括进气口、 出气口以及真空负压端, 真空发生器 4的真空负压端通过气管 8与真空吸附口 9连通, 真空 用压缩气源 15供给压缩气体至真空发生器 4的进气口, 从出气口高速流出, 从而在气管 8内 和真空吸附口 9处产生真空, 利用真空对所需要输送的物料进行吸附, 配合物料的输送。
真空发生器 4可以根据需要采用多级真空发生器, 从而避免了真空泵或其他类型气泵所 产生的噪声污染, 能耗也将大大降低。 每个真空发生器 4上均安装有消声器 5, 用来进一步 降低噪声污染。 气管 8上设置至少一个过滤器 7, 用来对气体中夹杂的渣屑进行过滤, 保证 气路通畅。
一组真空分选组件中的真空发生器 4可以为多个, 用来对与该组真空分选组件对应的同 一个输送部件上的多个物料进行同时吸附, 提高物料的输送效率。 每一个真空发生器 4至少 对应一个真空用压缩气源 15, 即可以根据实际需要对应使用多个真空用压缩气源 15。
真空用压缩气源 15与真空发生器 4之间通过真空控制阀 1以控制压缩气体的通断,真空 控制阀 1可以根据实际需要采用多种类型的电磁阀, 例如常闭型电磁阀。 真空控制阀 1正压 压缩空气, 即使存在较小的渣屑进入真空发生器 4的阀芯, 也会被从真空发生器 4的出气口 吹出, 而不会损坏阀芯, 且真空控制阀 1均只控制正压的清洁干燥的压缩空气进入, 因此都 不会有任何玻屑等异物进入阀门而造成堵塞、 磨损等不良情况。
本实施例中, 进一步令气管 8和 /或真空发生器 4与一反吹用压缩气源 16相连通, 反吹 用压缩气源 16供给压缩气体至气管 8中, 用以将气管 8中的渣屑从真空吸附口 9处吹出、并 将真空发生器 4中的渣屑从其出气口吹出。反吹用压缩气源 16通过反吹控制阀 2控制压缩气 体的通断, 反吹控制阀 2可以根据实际需要采用多种类型的电磁阀, 例如常闭型电磁阀。 这 样, 在真空发生器 4处于工作状态时, 反吹用压缩气源 16通过反吹控制阀 2控制停止供入压 缩空气, 令分选系统完成对物料的吸附。 当真空发生器 4处于非工作状态时, 可以通过反吹 控制阀 2控制启动供入压缩空气, 完成对气管 8中尘屑的反吹清除。 这样, 通过增设反吹功 能, 可增强吸瓶的有效性, 降低对单路气道的真空度和气流量要求, 同时还能清理挂在气管 8入口或阀芯处的玻璃碎片等。
本实施例中, 真空发生器 4和气管 8均安装于阀岛 3上, 阀岛 3为一集成式阀岛, 阀岛 3固定于阀岛安装板 (图中未示) 上。 真空发生器 4通过螺纹连接固定于阀岛 3上, 且真空 发生器 4的阀芯直接置于阀岛 3内, 气管 8通过快装接头 6连接于阀岛 3上。 整个阀岛 3上 至少共用两路气源,即阀岛 3上开设有用来与真空用压缩气源 15相连通的真空用压缩气体入 口 10、 用来与反吹用压缩气源 16相连通的反吹用压缩气体入口 11。 这样, 真空用压缩气体 入口 10将作为用于真空控制的压缩空气的总入口, 将其引入真空发生器 4中。反吹用压缩气 体入口 11将作为用于反吹控制的压缩空气的总入口,即使存在较小的渣屑进入了真空发生器 4的阀芯或气管 8中, 通过反吹用压缩气体入口 11引入压缩空气后, 也会被从与真空用压缩 气体入口 10相对的另一端 (即真空吸附口 9处) 吹出, 而不会损坏阀芯。 本实例中, 真空用 压缩气体入口 10通过阀岛 3与阀芯连通, 反吹用压缩气体入口 11通过阀岛 3连通于阀芯与 气管 8之间。
一个阀岛 3上可以根据实际需要集成多组真空分选组件, 即安装多个真空发生器 4、 开 设多组真空用压缩气体入口 10和反吹用压缩气体入口 11。 参见图 2的实例中, 实际上就集 成了两组真空分选组件。
如图 2和图 3所示, 本发明进一步提供一种出瓶装置, 包括检测部件(图中未示)、 好瓶 输送部件 12、坏瓶输送部件 13和控制部件 14, 检测部件包括图像采集单元和图像处理单元, 利用图像采集单元采集出瓶时的瓶体图像, 然后经过图像处理单元分析处理后判断是否为合 格瓶体, 即好瓶或坏瓶。 好瓶输送部件 12和坏瓶输送部件 13均为拨轮式输瓶机构, 控制部 件 14为工控机或电气柜, 用来对整个出瓶装置的工作过程进行实时控制。
本发明的出瓶装置还包括一个真空分选系统, 该真空分选系统包括采用上述结构的两个 真空分选组件, 即好瓶输送部件 12处对应设置一个真空分选组件, 坏瓶输送部件 13处也对 应设置一个真空分选组件。 两个真空分选组件中所有控制阀均由控制部件 14来控制。
当出瓶装置无瓶输出时, 好瓶输送部件 12和坏瓶输送部件 13下方的真空分选组件的所 有控制阀均不动作。 由于控制阀均为常闭阀, 所以真空吸附作业和反吹作业均不执行, 可减 少噪音, 节约气源。
当经检测部件的判断, 出瓶装置输出端的输出为好瓶时, 好瓶输送部件 12下方真空分选 组件的真空控制阀 1打开, 使压缩空气由真空用压缩气体入口 10进入, 真空发生器 4开始工 作, 使当前的气管 8 (气流通道) 中产生真空, 从而吸住好瓶输送部件 12上的瓶子; 同时, 与之对应的坏瓶输送部件 13下方真空分选组件的反吹控制阀 2打开,使压缩空气由其上的反 吹用压缩气体入口 11进入进行反吹作业。
当经检测部件的判断, 出瓶装置输出端的输出为坏瓶时, 坏瓶输送部件 13下方真空分选 组件的真空控制阀 1打开, 使压缩空气由真空用压缩气体入口 10进入, 真空发生器 4开始工 作, 使当前的气管 8 (气流通道) 中产生真空, 从而吸住坏瓶输送部件 13上的瓶子; 同时, 与之对应的好瓶输送部件 12下方真空分选组件的反吹控制阀 2打开,使压缩空气由其上的反 吹用压缩气体入口 11进入进行反吹作业。
通过上述优化后的控制系统及控制方式, 利用真空吸附与反吹作业的交替, 可以大大节 约气源; 在无瓶输出时, 还能使整个分选系统处于停止工作状态, 降低能耗和噪声。 同时, 这样交替运行, 能够通过反吹将瓶体吹向相对布置的另一个输送部件中, 保证瓶体分选进入 的可靠性, 最终为提高整体输瓶速度提供了有力保证。
以上仅是本发明的优选实施方式, 本发明的保护范围并不仅局限于上述实施例, 凡属于 本发明思路下的技术方案均属于本发明的保护范围。 应当指出, 对于本技术领域的普通技术 人员来说, 在不脱离本发明原理前提下的若干改进和润饰, 例如采用与真空发生器 4原理等 同的真空发生设备, 均应视为本发明的保护范围。
