Description

胶囊填充线的改进或与之相关的改进
本公开涉及胶囊填充线的改进或与之相关的改进。本公开包括操作和清洁胶囊填充线的方法以及用于胶囊填充线的消融单元。
背景技术
胶囊填充线需要对其机器进行定期清洁和维护,以便确保令人满意的性能。通常,清洁和维护程序需要在执行这些程序时停止胶囊填充线。这会影响胶囊填充线的生产率和产量。因此,需要使执行清洁和维护程序所花费的时间最小化。
一些胶囊填充线包括用于将胶囊盖密封到胶囊体上的密封头。密封头可以是热密封头。密封头可在操作期间被填充操作中的残留物污染。此类残留物可影响密封头的性能,并且因此必须定期去除。目前,残留物常常通过使用金属丝清洁刷来去除。该程序会导致胶囊填充线的停机时间。另外,该程序是劳动密集型的,并且可能导致密封头损坏。因此,需要用于清洁和维护包括密封头的胶囊填充线的改进方法。
发明内容
在第一方面,本公开提供了一种清洁胶囊填充线的密封头的方法,该方法包括操作消融单元以照射密封头以消融掉密封头上的残留物。
在第二方面,本公开提供了一种操作胶囊填充线的方法,该方法包括:
i)向胶囊填充线供应一批胶囊体和一批可食用产品;
ii)操作胶囊填充线使得通过用可食用产品至少部分地填充每个胶囊体并操作胶囊填充线的密封头以用胶囊盖密封每个胶囊体来生产多个填充胶囊;以及
iii)间歇地清洁胶囊填充线的密封头;
其中清洁密封头包括操作胶囊填充线的消融单元以照射密封头以消融掉密封头上的残留物。
有利地,本申请人已经发现使用消融单元来照射密封头以消融掉密封头上的残留物会使得胶囊填充线的停机时间减少。另外,就算没有完全消除也可能非常显著地减少清洁和维护程序对密封头的损坏。
已经发现,在可食用产品是粉末或颗粒的情况下,这些优点尤其明显。已经发现,粉末和颗粒(例如咖啡颗粒、咖啡粉、糖和巧克力粉)特别容易堆积在密封头上。这被认为至少部分地是由于粉末和颗粒具有低粒度和重量,这导致它们易于雾化并悬浮在密封头附近的空气中。因此,在实践中,通常不可能防止一部分粒子与密封头接触。在密封头是热密封头的情况下,该问题会更加严重。热密封头的高温致使粉末和颗粒部分地熔化并在接触时粘在热密封头上。此外,在胶囊填充线上,密封头可能具有复杂的特征,例如脊和凹槽,它们具有期望公差小至0.1mm至0.2mm的小尺寸。残留物的堆积
已经发现,本公开的方法和设备在从密封头(包括热密封头)去除粉末和颗粒残留物方面是有效的,同时维持密封头的状况(包括其复杂特征)。
来自胶囊的残留物也可能堆积在密封头上,特别是在使用热密封头的情况下。与粉末状和颗粒状的可食用产品一样,已经证明难以在不损坏密封头的情况下有效地清洁掉密封头上的此类残留物。
还发现,本公开的方法和设备在从密封头(包括热密封头)去除胶囊残留物(包括其复杂特征)方面是有效的。

在以下描述中,仅以举例的方式,将针对胶囊的填充来说明胶囊填充线,其中每个胶囊由如图2所示的胶囊体11和如图3所示的胶囊盖12形成。胶囊体11和胶囊盖12是以商标名称

胶囊体11可各自在填充站1处定向成使碗形体的嘴部面朝上,并且可食用产品然后可被沉积到胶囊体11的内部空隙中。
通常,填充站1将同时填充多个胶囊体11。例如,可同时填充2个、4个、20个、24个、32个、40个或更多个胶囊体11。
然后可通过输送机8将含有可食用产品的胶囊体11移动到封盖站2。封盖站2可提供用于从该批胶囊盖7拾取胶囊盖12并将它们放置在胶囊体11上的装置。另选地,如上所述,此类装置可作为密封站3的一部分或在胶囊填充线的另一个站处提供。

辐射发射器60可在壳体40内移动。例如,辐射发射器60可被配置为沿着壳体40的至少一个轴线横穿以将辐射扫过该密封头或每个密封头23。在所示示例中,辐射发射器60可包括激光头单元61和激光发射窗口62。激光头单元61可在线性驱动机构上安装在壳体40的后部部分41内。激光头单元61可通过幕帘机构56延伸到壳体40的前部部分42中,并且激光发射窗口62可被定向成指向开口47。
激光头单元61可通过线性驱动机构沿着前部部分42移动以便横穿前部部分42的长度,以便通过激光发射窗口62发射的激光辐射可扫过密封头单元9的密封头23。
激光头单元61可被配置为沿着前部部分42以固定速度扫掠。另选地,线性驱动机构可被配置为顺序地将激光头单元61定位在多个离散位置。例如,可配置备用位置以及两个、三个、四个、五个或更多个消融位置。在每个消融位置处,激光头单元61可被配置为照射密封头单元9的一个或多个密封头23。激光头单元61可包括2D光学器件,以允许从每个消融位置将线性辐射束(例如激光)扫过密封头23中的一个或多个密封头。在所示示例中,配置了备用位置和五个消融位置,并且在每个消融位置处,2D光学器件允许照射上部阵列21的两个密封头23和下部阵列22的两个密封头。
消融单元10还可包括排气系统70,如图6所示,该排气系统用于从密封头23的附近排出气体。排气系统70可包括壳体40中的多个排气孔74,该多个排气孔通过排气歧管72连接到排气管线71。多个排气孔74可位于壳体40的前部部分42的上表面45中。排气孔74可通过软管73或类似导管连接到排气歧管72。每个软管可包括控制阀75,该控制阀允许单独地控制通过每个软管73的流动。
如图5以及图8至图10所示,消融单元10还可包括传动装置31、32,该传动装置用于使壳体40(包括辐射发射器60)在缩回位置与接合位置之间移动。传动装置31、32可被配置为通过使消融单元10在一个或多个轴线上相对于支撑框架30平移来将消融单元10移动到接合位置。传动装置31、32可使消融单元10相对于支撑框架30移动。传动装置31、32可包括用于使消融单元10沿着x轴移动的第一部分31,其中x轴可平行于输送机8的移动方向。沿着x轴的移动可以是平移的。传动装置31、32的第二部分32可使得消融单元10能够沿着z轴移动,其中z轴可垂直于输送机8的移动方向。沿着z轴的移动可以是竖直的。

如图10所示,当壳体40处于接合位置时,壳体40的开口47可能够接合在密封头单元9上或抵靠该密封头单元,以限定含有密封头23和辐射发射器60的基本上封闭的容积。有益地,这有助于抑制辐射并防止激光散射到消融单元10外部。应注意,密封头单元9已经旋转到其清洁取向以使得能够实现这一点。在接合位置中,壳体40的开口47和辐射发射器60可被向侧面引导。
如图8所示,在缩回位置中,消融单元10可缩回并且远离输送机8升高,以便在填充、封盖和密封操作期间不会妨碍胶囊填充线的操作。在图8中,密封头单元9仍被示出为处于其清洁取向,但能自由旋转回到其密封取向(以虚线示出)。

将消融单元10与密封头23或密封头单元9接合优选地包括将消融单元10的壳体40接合在密封头23上或抵靠该密封头。
在该方法期间,密封头单元9可从其密封取向移动到其清洁取向。该移动可包括将密封头单元9旋转大于30度、任选地大于45度、任选地大于60度、优选地90度、任选地至多120度。
在密封取向上,密封头单元9和密封头23可面朝下。在清洁取向上,密封头23可面朝侧面。在将消融单元10与密封头单元9脱离之后,该方法还可包括将密封头单元9旋转回到密封取向。
清洁操作可包括使用从消融单元10的激光头单元61发射出的辐射来照射密封头23。
图12是经历激光照射的密封头23的一部分的示意图。线性激光束90由激光头单元61的2D光学器件产生。在该示例中,线性激光束90正从右向左转向,如由箭头示意性地指示,以扫过整个密封头23。来自可食用产品和/或胶囊体和/或胶囊盖的残留物91存在于密封头23的左手侧。密封头23的右手侧的残留物已经通过线性激光束90的消融效应去除。
在消融期间,残留物的消融可能会产生气体。因此,优选的是在消融期间通过使用排气系统70从密封头23的附近排出气体。通过例如真空泵或风扇向排气管线71施加负压。这导致可能从密封头23移出的消融气体和残留物粒子通过排气孔74、软管73和排气歧管72被吸入排气管线71中。可选择性地操作控制阀75以使得排气能够一次流过一个或多个软管73。优选地,排气孔74布置在辐射发射器60的各个消融位置上方。可控制控制阀75以建立仅流过与辐射发射器60当前占据的消融位置相关联的排气孔74和软管73的排气流。这可有益地减小排气系统70所需的真空泵或风扇的大小。
可在消融期间移出的较大残留物粒子(其可能太大而不能通过排气系统70排出)可在壳体40的前部部分42内落下。这些粒子可被捕获在料斗53中,该料斗可设在前部部分42的基部处。料斗53可包括在前部部分42的下表面44中的盘、碗或凹陷,或者可简单地包括下表面44本身。可在与前开口47毗邻的下表面的前部提供升高的唇缘。可经由前开口47定期从壳体40清除移出的粒子。
有益地,本公开提供了用于维持密封头23的状况的改进设备和方法。举例来说,图13示出了通过现有技术过程清洁的密封头的图片。在该现有技术过程中,密封头23已通过应用旋转金属丝刷移出残留物而被清洁。在3000次清洁循环之后,对密封头的点蚀和损坏92清晰可见。相比之下,图14示出了使用根据本公开的消融进行17000次清洁循环之后相同类型的密封头23。密封头23的状况明显优于图13中所示的状况。
