Description

包装和充填机器
技术领域
本发明涉及一种用来将某物充填并包装成容器内的饮料的包装和充填机器。
背景技术
在制造充填例如牛奶、矿泉水、茶、果汁、汤、酒等液体食品的包装容器时，使用幅材状层压包装材料。幅材状包装层压材料被叠接成随后的包装层压材料的接片。包装的容器因此经由热密封、超声密封或类似方式而连续密封包装层压材料来形成。例如在包装和充填机器内，包装层压材料被叠接成随后的包装层压材料的接片。条带在包装层压材料的边缘上连续结合。包装层压材料形成管状形状。包装材料的两个端侧彼此重叠以便形成重叠部。重叠部通过覆盖纵向密封的内边缘部分表面的条带压靠，并且重叠部沿着纵向通过纵向密封元件密封。在无菌室内的无菌覆盖气氛中，在管状包装成材料内充填液体食品并切割包装层压材料的同时，包装层压材料在横向上通过横向密封装置密封。形成枕形的初步容器。初步容器进一步被形成预定形状，并且包装容器得以完成。
图4是表示包装和充填机器的实例的外观透视图。卷筒状幅材状包装层压材料1被装载到包装和充填机器中。包装层压材料1包括层压纸基底以及位于纸基底的两侧上的聚乙烯树脂层的柔性层压制品。如果需要的话，包括铝箔、气体阻挡树脂和类似物的阻挡层形成在纸基底和薄膜层之间。装饰物被印刷在与包装容器14的表面相对应的部分上。
展开的包装层压材料1通过输送装置的供应器连续输送，并且经由弯曲滚子和缓冲滚子输送到条带施加器3。通过随后条带的叠接，条带2通过条带施加器被连续施加到包装层压材料1的一个边缘上。
如果需要的话，拉片通过拉片施加器被施加到包装层压材料1。包装层压材料1被输送到消毒罐4，并且在消毒罐4内通过过氧化氢和类似物的消毒液体进行消毒。包装层压材料1被承载到气刀5以便通过气刀5进行干燥。包装层压材料1被承载到无菌室40中，确保液体食品在无菌的气氛中充填管状包装材料。包装层压材料1通过成形环6和其它成形环逐渐变形，以便形成管状形状。管状包装层压材料1通过来自纵向密封装置的预热装置8的热空气预热以便纵向密封。液体食品从充填管7的出口的底端充填到管状包装层压材料1中。
将液体食品从充填管充填到管状包装材料内的预定液位的实例在图5中表示。充填管7的垂直部分被插入管状包装材料1的内部下部。上游部分被连接到控制阀32。圆柱形浮体34围绕充填管7的垂直部分的周边布置。在液体食品中浮动并位于管状包装材料1和充填管7之间的浮体34以能够上下自由运动的方式围绕充填管7的垂直部分的外表面放置。待检测装置35(磁体、发送器、标签和类似物)被安装到浮体34上。检测器31被配置在管1的外侧。检测器31将来自待检测装置的信号的强弱变化转换成电流，并且检测器作为电信号进行输出。检测器分别在大于预定液位时向控制装置33输出停止信号，并且在小于预定液位时向控制装置33输出打开信号。流动控制阀32被装备在充填管7的上游部分内，并且流动控制阀32通过控制装置33进行控制。液体的液位被调节到预定液位(对比专利文件1)。
管状包装层压材料1被向下引导并且被承载到横向密封装置10，如图4所示。管状包装层压材料1通过压力机沿着横向热密封，并且形成容器形状。横向密封的包装层压材料通过刀切割，并且形成枕形的初步容器(预成形主体)13。
横向密封装置10的详细局部截面图在图6中表示。首先，在此实施例中，具有充填食品的管状包装材料1通过上部一对密封爪10a和相对爪11得到保持。在管状包装材料1被向下承载与唯一一个包装容器相对应的长度距离的同时，它通过一对上部成形翼片41和41得到保持，并且它被形成大致容器形状。两个横向密封区域通过横向密封横向地形成。被连接的枕形预成形主体的密封区域的中部通过刀42进行切割，并且形成分离的枕形预成形主体13。在图6所示的实施例中，为了高速横向密封、预成形和切割，装备两对密封爪和相对爪以及成形翼片，并且完成横向密封、预成形和切割步骤的第一对被撤离到一旁，并且它向上返回，重复下一个横向密封、预成形和切割步骤。
初步容器13被输送并通过最终成形装置15成形为最终形状，如图4所示，并且生产出充填液体食品的包装容器14。

发明内容
本发明所要解决的问题
在上述包装和充填系统中，管内充填的液体食品的压力是与液体离开液位的深度相对应的正压。在包装材料通过成形翼片成形时，管内的液体食品的正压与成形翼片的外部压力结合，以便形成包装材料井池。另外，保持这种正压也保持了充填食品的良好卫生状态。即，即使包装材料具有微小的裂纹、裂缝和小孔，液体食品只从这些点泄漏到外侧，而没有任何外部环境物质侵入管，并且不会污染管内的液体食品。
本发明的目的在于提供一种包装和充填机器，该机器能够通过将管内的液体食品的压力保持正压而方便地通过成形翼片进行预成形，即使液体食品的压力由于液体食品压力的变化而降低也能够防止液体食品的压力降低到负压，并且能够防止外部环境材料侵入管。
解决问题的措施
在本发明的包装和充填机器中，幅材状包装层压材料被叠接成随后的幅材状包装层压材料的接片，幅材状包装材料被连续供应并成形为管状形状，在包装材料的两个端部重叠的管沿着纵向纵向密封，液体食品从充填管充填到连续和垂直向下输送的管状包装材料内，直到充填管的出口以上的预定位置的液位，同时管通过密封爪和相对爪沿着横向保持在该液位以下，并且被向下拉动，管被横向密封，同时管通过密封爪和相对爪沿着横向保持在该液位以下，并且管在通过成形翼片进行预成形的同时得到保持，管在横向密封区域内被切割，并且制成该包装容器，其特征在于：该包装和充填机器包括压力凸缘和正压保持装置，所述压力凸缘在管状包装材料内该液位以下围绕充填管的周边配置，所述压力凸缘控制管内充填的液体食品从下部到上部的自由流动，以便将压力凸缘以下的管内的液体食品的压力保持在正压，并且方便地通过成形翼片进行预成形，正压保持装置吸收压力凸缘以下的管内的液体食品的压力的波动，并且防止液体食品压力降低到负压，以便将压力凸缘以下的管内液体食品的压力保持在正压。
在本发明的优选实施例中，正压保持装置在充填管的周边上上下自由运动，并且是通过由凸缘的本身重量向下运动的第一力和通过从下部到上部流动的液体食品的上游向上运动的第二力的平衡而定位在预定位置及其附近的压力凸缘。
在本发明的优选实施例中，正压保持装置在充填管的周边上上下自由运动，并且是通过由管内的内外磁极之间的磁力向下运动的第一力和通过从下部到上部流动的液体食品的上游向上运动的第二力的平衡而定位在预定位置及其附近的压力凸缘。
在本发明的优选实施例中，正压保持装置是固定在充填管的周边上的压力凸缘，具有穿过孔，并具有位于穿过孔内的单向阀，以便在液体食品压力降低的步骤中使得液体食品从上部向下流动，并且在其它步骤控制从液体食品的下部向上流动。
在本发明的优选实施例中，装备了正压保持装置的添加调节装置，该装置在压力凸缘周围的下部位置或者上部和下部位置处将液体食品从充填管添加到管内，添加调节装置通过液体食品压力的周期波动而对液体食品压力降低到负压进行吸收，并且防止任何外部环境物质侵入管。
在本发明的优选实施例中，通过液体食品压力的波动来降低液体食品压力的部分是密封爪、相对爪和成形翼片之上以及至少在压力凸缘之下的第一降低部分，正压保持装置的添加调节装置是穿过充填管的管壁以接收至少第一降低部分的液体食品压力的周期波动的孔或单向阀。
在本发明的优选实施例中，正压保持装置的流动控制装置装备在压力凸缘内，流动控制装置通过压力凸缘控制液体食品从下部到上部的流动，打开液体食品在压力凸缘周围从上部到下部的流动，并且对液体食品的压力降低到负压进行吸收，以便防止外部环境物质侵入管。
在本发明的优选实施例中，正压保持装置的流动控制装置是围绕充填管的周边配置在压力凸缘以下的环状浮动阀，其具有根据液体食品的流动上下自由运动的能力，压力凸缘具有上下穿过凸缘的穿过孔，环状浮动阀根据液体食品的流动局部或完全地打开或堵塞穿过孔。
在本发明的优选实施例中，正压保持装置升高无菌室内的气氛的压力，并将液体食品压力升高经过该液位，并对液体食品压力降低到负压进行吸收，以便防止外部环境物质侵入管。
本发明的效果
根据本发明，显示出以下的有益功能，并且提供有利效果。在本发明的包装和充填机器中，幅材状包装层压材料形成管状形状，在包装材料的两个端部重叠的管沿着纵向纵向密封，液体食品从充填管充填到连续和垂直向下输送的管状包装材料内，直到充填管的出口以上的预定位置的液位，同时管通过密封爪和相对爪沿着横向保持在该液位以下，并且被向下拉动，管被横向密封，同时管通过密封爪和相对爪沿着横向保持在该液位以下，并且管在通过成形翼片进行预成形的同时保持，管在横向密封区域内被切割，并且制成该包装容器。
由于幅材状包装层压材料被叠接成随后的幅材状包装层压材料的接片，在幅材状包装材料的剩余量低时，包装可以连续充填而不停止。
由于在充填液体食品的幅材状包装材料的液位以下横向密封，不需要的空气不停留在容器内，并且保持良好的质量。在包装和充填过程中，管内充填的液体食品的压力是与液体离开液位的深度相对应的正压。在包装材料形成成形翼片时，该材料可以在这种正压以下良好形成。
在本发明的特征中，压力凸缘在管状包装材料中在液位以下配置在充填管的周边上。在管状包装材料向下承载的同时，材料通过密封爪和相对爪快速夹持，并且另外材料通过一对成形翼片快速夹持。管状包装材料内的液体被推动，并且管内的液体食品的压力突然升高，并且正压可以是过压。过大的正压使得液位快速升高，并且形成不稳定的振动，并造成液位控制困难。即这种过大正压使得液位快速升高，使得液位不确定地振动。例如图5所示的浮体34大幅上下振动，因此控制装置33难以控制液位。
在本发明中，压力凸缘控制管内充填的液体食品从下部到上部的自由流动，以便将压力凸缘以下的管内的液体食品的压力保持在适当的正压，并且容易地通过成形翼片进行预成形。另外，即使液体食品从下部到上部反向流动，可以控制反向流动，并且可以控制液位的快速升高。由于液体食品压力不降低到负压，可以防止外部环境物质侵入管。例如压力凸缘36在管状包装材料1内在液体以下配置在充填管1的周边上，如图5所示。即使通过密封爪和相对爪快速保持在压力凸缘以下，并且通过一对成形翼片快速保持，液体食品从下部到上部反向流动，压力凸缘36可控制反向流动，并且控制液位的快速升高，并且将液体食品的压力保持在足够的正压。
由于液体食品压力的波动，管内充填的液体食品在围绕压力凸缘的管内的压力处于极低的正压或负压的危险中。图2表示液体食品从充填管7供应的总体实例以及液体食品在通过密封爪、相对爪和成形翼片进行横向密封的过程中的流动和运动。如图2(A)所示，在管状包装材料在箭头c的方向上被承载到下部时，管通过成形翼片、密封爪10a和相对爪11快速夹持，管状包装材料内的液体被推动，并且管内的液体食品的压力升高，并且液体在箭头(a)的方向上反向流动。压力凸缘36控制反向流动，并且保持成形所需的正压。
由于管内的液体食品的压力经过管内的整个液体食品，而不考虑压力凸缘36的存在，如图2(B)所示，管内的液体由于惯性在箭头(e)的方向上反向流动。但是，液体从凸缘下部到上部的运动由于压力凸缘36的存在而得到分布，并且在凸缘以上缺乏液体(在第二降低部分)，并且形成短缺(d)。短缺(d)在图2(B)中表示成虚拟泡沫(virtual foam)。因此，管内充填的液体食品的压力处于极低正压或负压的危险中。升高的液体由于短缺而快速降低，并且因此液体食品的压力再次增加。以此方式，液位由于振动而重复。
在包装和充填机器的实例中，图3是其竖轴表示压力凸缘以上(第二降低部分)的液体食品的压力以及其横轴表示横向密封(通过密封爪和相对抓保持)、预成形和切割步骤的一个循环的时间的图表。管内的液体食品的压力在通过成形翼片、密封爪和相对爪快速保持时(在箭头指出的时间周期(j))快速升高。它们与图3的峰值(h)和(i)相对应。管内的液体食品的压力经过管内的整个液体食品，并且管内的液体由于惯性反向流动到上部。液体从凸缘下部到上部的运动由于压力凸缘36的存在而得到分布，并且凸缘以上(在第二降低部分)缺乏液体，压力凸缘以上(在第二降低部分)的液体食品的压力降低。它们对应于短缺的底部(g)，因此，液体食品的压力再次升高。以此方式，液位由于振动而重复。
随后，如图2(C)所示，管状包装材料1在箭头(c)的方向上向下承载，并且压力凸缘36以下位置处(第一降低部分)的管状包装材料内的容积增加。压力凸缘36以上的液体在箭头(b)的方向上供应(图2(C))，除非与容积增加相对应的液体食品通过充填管出口7a供应。但是，压力凸缘36使得该供应得以分布。如图2(C)所示，压力凸缘36以下位置处(第一降低部分)的管状包装材料的容积在管状包装材料通过密封爪10a和相对爪11向下拉动时快速增加。缺乏液体食品的供应量，并形成短缺(d)。短缺在图2(C)中以虚拟泡沫表示。因此，管内充填的液体食品的压力处于极低正压或负压的危险中。
在包装和充填机器的实例中，图7是其竖轴表示压力凸缘(以下第一降低部分)的液体食品的压力以及其横轴表示横向密封(通过密封爪和相对抓保持)、预成形和切割步骤的一个循环的时间的图表。管内的液体食品的压力在通过成形翼片、密封爪和相对爪快速保持时(在箭头指出的时间周期(j))快速升高(见图7的峰值(h))。压力凸缘以下的位置处(第一降低部分)的管状包装材料的容积在管状包装材料通过密封爪和相对爪向下拉动时快速增加。缺乏液体食品的供应量。管内充填的液体食品的压力处于极低正压或负压的危险中(见图7的底部(g))。
在本发明的特征中，正压保持装置对压力凸缘以下的管内液体食品的压力的波动进行吸收，并且防止液体食品压力降低到负压，以便将压力凸缘以下的管内的液体食品的压力保持在正压。由于正压保持装置对液体食品的压力的波动进行吸收，并且防止液体食品压力降低到负压以便将液体食品压力保持在正压，成形翼片可容易地进行预成形，由于液体食品压力不降低到负压，可以防止外部环境物质侵入管。即，由于正压保持装置将液体食品的压力保持在正压，即使包装材料具有微小裂纹、裂缝和小孔，液体食品只从这些点泄漏到外侧，但是没有任何污染物污染管内的液体食品。被充填的食品保持在良好的卫生状态。
在本发明的优选实施例中，正压保持装置在充填管的周边上上下自由运动，并且是通过由凸缘的本身重量向下运动的第一力和通过从下部到上部流动的液体食品的上游向上运动的第二力的平衡而定位在预定位置及其附近的压力凸缘。在管通过密封爪和相对爪快速保持并且管通过一对成形翼片快速夹持时，管状包装材料的容积由于该快速保持而减小。管内的液体食品即将快速升高，但是控制管内充填的液体食品从上部自由流动到下部的压力凸缘可以控制液体食品的向上反向流动。另一方面，在管状包装材料以高速向下拉动时，管状包装材料的压力凸缘以下的容积快速增加，并且待供应的液体食品量缺乏，并且管内的液体食品的压力降低。但是，通过由于不锈钢和类似材料的主体的压力凸缘的本身重量而向下运动的第一力，压力凸缘以下的容积减小，并且可以防止负压。
在本发明的优选实施例中，正压保持装置在充填管的周边上上下自由运动，并且是通过由管内的内外磁极之间的磁力向下运动的第一力和通过从下部到上部流动的液体食品的上游向上运动的第二力的平衡而定位在预定位置及其附近的压力凸缘。在管通过成对爪快速保持并且管通过一对成形翼片快速夹持时，管的容积由于快速保持而减小。管内的液体食品即将快速升高，但是控制液体食品从下部到上部流动的压力凸缘控制液体食品的向上反向流动。另一方面，在管状包装材料以高速向下拉动时，管状包装材料的压力凸缘以下的容积快速增加，并且待供应的液体食品量缺乏，并且管内的液体食品的压力降低。但是通过磁力产生的向下运动的第一力，压力凸缘以下的容积减小，并且可以防止负压。
在本发明的优选实施例中，正压保持装置是固定在充填管的周边上的压力凸缘，具有穿过孔，并具有位于穿过孔内的单向阀，以便在液体食品压力降低的步骤中使得液体食品从上部向下流动，并且在其它步骤控制从液体食品的下部向上流动。在管通过成对爪快速保持并且管通过一对成形翼片快速夹持时，管的容积由于快速保持而减小。管内的液体食品即将快速升高。但是具有控制液体食品从下部到上部流动的单向阀的压力凸缘控制液体食品的向上反向流动。另一方面，在管状包装材料以高速向下拉动时，管状包装材料的压力凸缘以下的容积快速增加，并且待供应的液体食品量缺乏，并且管内的液体食品的压力降低。但是由于将液体食品从上部向下流动的穿过孔内的单向阀，压力凸缘以下的容积减小，并且可以防止负压。
在本发明的优选实施例中，在本发明的优选实施例中，正压保持装置是添加调节装置，该装置在压力凸缘的下部位置(第一降低部分)或者在上部(第二降低部分)和下部位置(第一降低部分)处将液体食品从充填管添加到管内，添加调节装置通过液体食品压力的周期更大波动而防止液体食品压力降低到负压，并且防止任何外部环境物质侵入管。在本发明中，通过液体食品压力的波动来降低液体食品压力的部分包括所述的密封爪、相对爪和成形翼片、压力凸缘以上的第二降低部分以及压力凸缘以下的第一降低部分。在本发明中，至少压力凸缘以下的部分是所需要的。由于液体食品压力的降低，液体食品根据来自充填管的不同压力流到第二降低部分和第一降低部分。在本发明的优选实施例中，添加调节装置是防止反向流动的单向阀或者具有穿过充填管的壁的简单结构的孔。
如上所述，添加调节装置通过液体食品压力的周期波动，防止液体食品的压力降低到负压，并且防止外部环境物质侵入管。即使在纵向密封区域内在接片内出现裂纹或可能的间隙，外部环境物质或任何污染物也不从裂纹和间隙侵入管，并且不污染液体食品。保持食品的良好卫生状态。
在本发明的优选实施例中，流动控制装置装备在压力凸缘内，流动控制装置通过压力凸缘控制液体食品从下部到上部的流动，打开液体食品从压力凸缘的上部到下部的流动，并且对液体食品的压力降低到负压进行吸收，以便防止外部环境物质侵入管。在本发明的优选实施例中，流动控制装置是围绕充填管的周边配置在压力凸缘以下的环状浮动阀，其具有根据液体食品的流动上下自由运动的能力。压力凸缘具有上下穿过凸缘的穿过孔。环状浮动阀根据液体食品的流动局部或完全地打开或堵塞穿过孔。环状浮动阀部分或完全堵塞穿过孔，但是在包装材料的内表面和压力凸缘的最外面的周边之间具有间隙。一些液体食品穿过间隙流动。环状浮动阀的截面形状包括容易制造的截面圆形、截面矩形、驱动从上部流动的上升的流线形(弧形形状)以及控制从下部流动的向下凹入形状，优选的是流线形和向下凹入形状。
参考图12，说明本发明的特征的流动控制装置的操作和动作。在图12所示的实施例中，流动控制装置39设置在压力凸缘36以下。流动控制装置39是污染充填管7的周边配置的环状浮动阀39，根据液体食品的流动(x、y、z)具有上下自由运动的能力。压力凸缘36具有上下穿过凸缘的穿过孔36a，环状浮动阀39打开穿过孔36a(见图12(B))，并且部分堵塞穿过孔36a(见图12(A))。如图12(A)所示，在管通过成形翼片、密封爪10a和相对爪11快速夹持时，管状包装材料内的液体被推动，管内的液体食品的压力快速升高，并且液体在向上方向上反向流动(流动x)，经过压力凸缘36的穿过孔。环状浮动阀39根据流动(流动x)升高，并且接着部分堵塞压力凸缘36的穿过孔。因此，环状浮动阀39控制反向流动(流动x)，并且压力被保持在足以成形的正压。如图12(B)所示，在管状包装材料1被向下承载时，压力凸缘36以下位置处的管状包装材料的容积增加。液体食品通过充填管的出口7a供应(流动(z))。液体食品从压力凸缘36以上的上部供应(流动(y))，除非与增加容积相对应的液体食品通过充填管的出口7a供应。在液体食品不足时，液体食品的压力会是非常低的正压或负压。环状浮动阀39根据流动(y)向下运动，并且压力凸缘36的穿过孔36a被全部打开，见(图12(B))。因此，供应变得足够，并且液体食品的压力上岗，并且可以事先防止低的正压和负压。
如上所述，流动控制装置通过液体食品压力的周期波动来防止液体食品压力降低到负压，并且防止外部环境物质侵入管。即使在纵向密封区域内在接片内出现裂纹或可能的间隙，外部环境物质或任何污染物也不从裂纹和间隙侵入管，并且不污染液体食品。保持食品的良好卫生状态。
在本发明的优选实施例中，正压保持装置升高无菌室内的气氛的压力，并将液体食品压力升高经过该液位，并对液体食品压力降低到负压进行吸收，以便防止外部环境物质侵入管。为了确保无菌室内无菌，对于无菌室内的气氛压力来说，正常压力、低于正常压力的压力以及高于正常压力的压力在包装和充填机器的功能中并不繁琐。通常，无菌室内的压力针对高于正常压力的某些压力进行设定，并且无菌室通过将无菌空气从无菌室经由间隙连续排出来保持无菌。在本发明中，无菌室内气氛的压力被进一步升高，以便升高液体食品的压力。无菌室内的气氛的压力经由管上部的开口和该液位施加。压力大小根据例如无菌室的气密性、液体食品的类型以及液体食品的温度的多种参数来适当调节。
参考图13，说明提供无菌室内的气氛压力的本发明的特征。所示包装和充填机器的无菌室40覆盖正在输送的被消毒的幅材状包装材1、管状包装材料1、管状包装材料1的上部开口以及充填管7。无菌室通过从与消毒空气供应器39连接的排气开口38流动的消毒空气充填。从与消毒空气供应器39的通风压力的关系以及与管状包装材料1向下离开无菌室的各点的间隙40a的关系，固定无菌室内的气氛的压力。即，通过使得间隙40a气密，并且通过加强通风压力，升高并调节无菌室内的气氛的压力。
如上所述，无菌室内的气氛的升高压力通过液体食品压力的周期波动来防止液体食品的压力降低到负压，并且防止外部环境物质侵入管。即使在纵向密封区域内在接片内出现裂纹或可能的间隙，外部环境物质或任何污染物也不从裂纹和间隙侵入管，并且不污染液体食品。保持食品的良好卫生状态。
如上所述，本发明的包装和充填机器能够通过将管内的充填液体食品的压力保持在正压而容易地通过成形翼片进行预成形，并且即使液体食品的压力由于液体食品压力的上下波动，也能够防止液体食品的压力降低到负压，并且能够防止外部环境物质侵入管。

具体实施方式
下面参考附图详细说明本发明的工作模式。在此模式的包装和充填机器中，如图4所示，幅材状包装层压材料1被成形为管状形状，在包装材料的两端处重叠的管沿着纵向纵向密封，如图5所示，液体食品从充填管7充填到在无菌室40内垂直向下输送的管状包装材料内，直到充填管7的出口以上的预定位置的液位，同时该管通过密封爪10和相对爪11沿着横向得到保持，如图6所示，管1被横向密封，管通过成形翼片41、41在预成形的同时保持，管在横向密封区域内通过刀42切割，并且制成预成形的容器13。
[实例]
本发明的包装和充填机器的实例1的包装和充填机器的压力凸缘的截面在图1中表示。在此实施例中，正压保持装置在充填管7的周边上下自由运动，并且是通过由凸缘的本身重量向下运动的第一力和通过从下部到上部流动的液体食品的上游向上运动的第二力的平衡而定位在预定位置及其附近的压力凸缘。此实施例的压力凸缘36具有在充填管7的周边上下自由运动的凸缘主体36a、在下部具有开口部分的凸缘翼部36b以及在上部具有穿过孔36c。在管通过密封爪和相对爪快速保持并且管通过一对成形翼片快速夹持时，管状包装材料的容积由于快速保持而减小。管内的液体食品即将快速升高，但是凸缘翼部36b可以控制液体食品的反向流动。另一方面，在管状包装材料以高速向下拉动时，压力凸缘以下的管状包装材料的容积快速增加，并且管内的液体食品的压力降低。但是，由于液体食品通过不锈钢和类似材料的主体的凸缘本身重量而从上部到下部经过穿过孔36c，压力凸缘以下的容积减小，并且可以防止负压。
根据本发明的第二实例的包装和充填机器的压力凸缘的截面在图8中表示。在此实施例中，正压保持装置在充填管7的周边上上下自由运动，并且是通过由管内的内外磁极(36d、36e和36f)之间的磁力向下运动的第一力和通过从下部到上部流动的液体食品的上游向上运动的第二力的平衡而定位在预定位置及其附近的压力凸缘。此实施例的压力凸缘36具有在充填管7的周边上下自由运动的凸缘主体36a、具有下部内的开口部分的凸缘翼部36b、上部内的穿过孔36c以及嵌入下部的磁体。另外在管1的外侧，设置位于内部磁极36d外部的同极性磁极36e以及相反极性的磁极36f。在管通过成对爪快速保持并且管通过一对成形翼片快速夹持时，管状包装材料的容积由于快速保持而减小。管内的液体食品即将快速升高，但是凸缘翼部36b可以控制液体食品的向上反向流动。另一方面，在管状包装材料以高速向下拉动时，压力凸缘以下的管状包装材料的容积快速增加，并且管内的液体食品的压力降低。但是，由于液体食品从上部到下部经过穿过孔36c，凸缘通过磁极(36d和36f)的磁力向下运动，压力凸缘以下的容积减小，并且可以防止负压。
根据本发明的第三实例的包装和充填机器的压力凸缘的截面在图9中表示。在此实施例中，正压保持装置在充填管7的周边上上下自由运动，并且是通过由管内的内外磁极(36d、36g)之间的磁力向下运动的第一力和通过从下部到上部流动的液体食品的上游向上运动的第二力的平衡而定位在预定位置及其附近的压力凸缘。此实施例的压力凸缘36具有在充填管7的周边上下自由运动的凸缘主体36a、具有下部内的开口部分的凸缘翼部36b、上部内的穿过孔36c以及嵌入下部的磁体36d。另外设置管1外侧的电子磁体36g。在管通过成对爪快速保持并且管通过一对成形翼片快速夹持时，管状包装材料的容积由于快速保持而减小。管内的液体食品即将快速升高，但是凸缘翼部36b可以控制液体食品的向上反向流动。另一方面，在管状包装材料以高速向下拉动时，压力凸缘以下的管状包装材料的容积快速增加，并且管内的液体食品的压力降低。但是，由于液体食品从上部到下部经过穿过孔36c，凸缘通过磁极(36d和36g)的磁力向下运动，压力凸缘以下的容积减小，并且可以防止负压。
根据本发明的第四实例的包装和充填机器的压力凸缘的截面在图10中表示。在本发明的此优选实施例中，正压保持装置是固定在充填管7上的压力凸缘，具有穿过孔36h并具有位于穿过孔36h内的单向阀36j，在液体食品压力降低的步骤中，使得液体食品从上部向下流动上下运动，并且在其它步骤控制从液体食品的下部向上流动。在管通过成对爪快速保持并且管通过一对成形翼片快速夹持时，管状包装材料的容积由于快速保持而减小。管内的液体食品即将快速升高，但是具有控制液体食品从下部流动到上部的单向阀36j的压力凸缘控制液体食品的向上反向流动。另一方面，在管状包装材料以高速向下拉动时，压力凸缘以下的管状包装材料的容积快速增加，并且待供应的液体食品量缺乏，管内的液体食品的压力降低。但是，由于位于穿过孔内且使得液体食品从上部向下流动的单向阀36j，液体食品在压力凸缘36以下供应，并且可以防止负压。
如上所述，压力凸缘控制管内充填的液体食品从下部到上部的自由流动以便将压力凸缘以下的管内的液体食品的压力保持在适当的正压，并且通过成形翼片容易地进行预成形。另外，即使液体食品从下部到上部反向流动，也可以控制反向流动，并且可以控制液位的快速上升。
此外，由于正压保持装置将液体食品的压力保持在正压，即使包装材料具有微小的裂纹、裂缝和小孔，液体食品只从这些点泄漏到外侧，而没有任何外部环境物质侵入管，并且不会污染管内的液体食品。被充填的食品被保持在卫生状态。如上所述，本发明的包装和充填机器能够通过将管内的充填液体食品的压力保持在正压而容易地通过成形翼片进行预成形，能够防止液位的快速升高。
根据本发明的包装和充填机器的第五实例的添加调节装置的外观在图11(A)中表示。充填管7被插入管状包装材料1内。圆柱形浮体34被配置到充填管7的外侧的环绕部。在液体食品内浮动的浮体34位于管状包装材料1和充填管7之间，并且被放入充填管7内，且具有上下自由运动能力。管1外侧的检测器31检测浮体34的位置。在此实例中，截面梯形的压力凸缘36在管状包装材料1内被装备在液位以下，并且配置在充填管7上。压力凸缘可将压力凸缘以下的管内的液体食品的压力保持在适当的正压，并且通过成形翼片容易地进行预成形。另外，即使液体食品从下部到上部反向流动，也可以控制反向流动，并且可以控制液位的快速上升。
在此实例中，添加调节装置39a另外在压力凸缘36以上的位置(在第二降低点)将充填管7内的液体食品供应到充填管7的外侧以及管1的内侧。添加调节装置通过液体食品压力的周期波动防止液体食品压力降低到负压，并且防止外部环境物质侵入管。在此实例中，添加调节装置39a具有两个孔39a，该孔具有穿过充填管7的管壁的简单结构。
根据本发明的包装和充填机器的第六实例的添加调节装置的外观在图11(B)中表示。充填管7被插入管状包装材料1内。圆柱形浮体34被配置到充填管7的外侧的环绕部。在液体食品内浮动的浮体34位于管状包装材料1和充填管7之间，并且被放入充填管7内，且具有上下自由运动能力。管1外侧的检测器31检测浮体34的位置。在此实例中，截面梯形的压力凸缘36在管状包装材料1内被装备在液位以下，并且配置在充填管7上。压力凸缘可将压力凸缘以下的管内的液体食品的压力保持在适当的正压，并且通过成形翼片容易地进行预成形。另外，即使液体食品从下部到上部反向流动，也可以控制反向流动，并且可以控制液位的快速上升。
在此实例中，添加调节装置39a另外在压力凸缘36以下的位置(在第一降低点)将充填管7内的液体食品供应到充填管7的外侧以及管1的内侧。添加调节装置通过液体食品压力的周期波动防止液体食品压力降低到负压，并且防止外部环境物质侵入管。在此实例中，添加调节装置39a具有两个单向阀39a，该单向阀具有穿过充填管7的管壁的简单结构。
在以上实例中，图3和图7所示的液体食品压力的底部(g)在箭头方向上得到改进，并且压力凸缘36以上(第二降低点)的液体食品压力升高30％。另外，除了以上实例之外，单个或多个添加调节装置可以配置在第一降低点和第二降低点两者上。
根据本发明的包装和充填机器的第七实例的流动控制装置的外观在图12(A)、图12(A)和图5中表示。充填管7被插入管状包装材料1内。圆柱形浮体34被配置到充填管7的外侧的环绕部。在液体食品内浮动的浮体34位于管状包装材料1和充填管7之间，并且被放入充填管7内，且具有上下自由运动能力。管1外侧的检测器31检测浮体34的位置。
在此实例中，截面梯形的压力凸缘36在管状包装材料1内被装备在液位以下，并且配置在充填管7上。压力凸缘36具有上下穿过的穿过孔36x。压力凸缘可将压力凸缘以下的管内的液体食品的压力保持在适当的正压，并且通过成形翼片容易地进行预成形。另外，即使液体食品从下部到上部反向流动，也可以控制反向流动，并且可以控制液位的快速上升。
在此实例中，环状浮动阀39被装备在压力凸缘36以下。根据液体食品的流动(x、y、z)，环状浮动阀39围绕充填管7的周边配置，且具有上下自由运动的能力。压力凸缘36具有上下穿过凸缘的穿过孔36a，并且环状浮动阀39打开穿过孔36a，并且部分堵塞穿过孔36a。如图12(A)所示，在横向密封过程中管被快速夹持时，液体被推动，并且管内的液体食品的压力快速升高，并且液体在向上方向(流动(x))上反向流动经过压力凸缘36的穿过孔36a。环状浮动阀39根据流动(流动(x))升高，并且接着压力凸缘36的穿过孔36a被部分堵塞。因此，环状浮动阀39控制反向流动(流动(x))，并且压力保持在足以成形的正压。
如图12(B)所示，在管状包装材料1向下承载时，压力凸缘36以下位置处的管状包装材料的容积增加。环状浮动阀39根据流动(y)向下运动，并且压力凸缘36的穿过孔36a完全打开。因此，供应变得足够，并且液体食品的压力升高，并且可以事先防止低的正压和负压。
在以上实例中，图7所示的底部(g)在箭头的方向上得到改进，压力凸缘36以下(第一降低点)的液体食品压力升高16％。另外除了以上环状浮动阀之外，可以将单向阀配置在穿过孔内。
根据本发明的包装和充填机器的实例的流动控制装置的外观在图13和图5中表示。充填管7被插入管状包装材料1内。圆柱形浮体34被配置到充填管7的外侧的环绕部。在液体食品内浮动的浮体34位于管状包装材料1和充填管7之间，并且被放入充填管7内，且具有上下自由运动能力。管1外侧的检测器31检测浮体34的位置。
在此实例中，截面板形的压力凸缘36在管状包装材料1内被装备在液位以下，并且配置在充填管7上。另外，它可以是截面梯形的压力凸缘。压力凸缘可将压力凸缘以下的管内的液体食品的压力保持在适当的正压，并且通过成形翼片容易地进行预成形。另外，即使液体食品从下部到上部反向流动，也可以控制反向流动，并且可以控制液位的快速上升。
在该实施例中，正压保持装置升高无菌室内的气氛的压力，并且将液体食品的压力升高经过液位，并且对液体食品压力降低到负压进行吸收，从而防止外部环境物质侵入管。无菌室内的气氛的压力升高以便升高液体食品的压力。无菌室内的气氛的压力经由管上部的开口和液位施加。压力大小根据例如无菌室的气密性、液体食品的类型、液体食品的温度的多种参数来适当调节。
图1所示的包装和充填机器的无菌室40包括通过腔室覆盖的空气空间，并且充填消毒空气。被消毒的幅材状包装材料1被输送到无菌室40，并且包装材料1被成形为管状形状，管状包装材料1经由桑巴开口，另外充填管7被插入无菌室。消毒空气从连接到消毒空气供应器39c的排气开口38供应。为了将消毒空气工业区39的通风压力与管状包装材料1向下离开无菌室的点的间隙40a平衡，无菌室内的气氛的压力被固定。即通过使得间隙40a气密，并通过加强通风压力，无菌室内的气氛的压力升高，并且被调节。因此，无菌室内的升高的压力通过液体食品压力的周期波动来防止液体食品压力降低到负压，并且防止外部环境物质侵入管。在以上实例中，图3和图7所示的底部(g)在箭头方向上得到改善。
出于示例和说明的目的进行以上描述，所述描述并不是旨在将本发明穷尽地局限于被披露的特定实施例。在以上的教导之下可以进行明显的变型或改型。
