Description

超声波发生器
技术领域
本发明涉及一种超声波发生器，特别是涉及一种用于将开口装置密封到用于形成密封包装的套筒的包装材料的孔上的超声波发生器。
背景技术
许多可倾倒的食品产品，例如果汁、巴氏灭菌或UHT(超高温加工)牛奶、酒、番茄酱等等都是在无菌包装材料制成的包装中商售。
该类型包装的典型例子是被称为Tetra Rex Aseptic(注册商标)的用于液体或可倾倒食品产品的包装，其是通过折叠和密封层压带包装材料而制成。
该包装材料具有基本上包括用于刚度和强度的基体层的多层结构，该多层结构可以包括纤维材料(例如纸)层，或矿物填充聚丙烯材料层；和多个热密封塑料材料层，例如聚乙烯膜，其覆盖基体层的两侧。
在用于如UHT牛奶之类的长期储存产品的无菌包装的情况下，包装材料还包括气体屏障和光屏障材料(例如铝箔或乙基乙烯醇(EVOH))层，其叠置在热密封塑料材料层上，该气体屏障和光屏障材料层进而覆盖有形成包装的最终接触食品产品的内表面的另一热密封塑料材料层。
根据已知的成形技术，将包装材料切割成坯料。坯料首先竖立以形成相应的开口套筒，所述开口套筒在其底端处被密封。然后，开口套筒通过其开口的顶端填充有可倾倒产品，然后密封顶端，以完成包装的形成。
还已知在用可倾倒产品填充套筒之前将开口装置施加到根据前述技术形成的相应开口套筒上。
特别地，所述开口装置包括：
-凸缘，其将被密封到所述套筒的在围绕其孔的区域中的包装材料上；
-颈部，其从所述凸缘突出；和
-盖，其被拧到颈部上。
为了将每个开口装置施加到相应套筒上，已知使用一种密封系统，该密封系统包括：
-砧座；和
-超声波发生器。
砧座可通过套筒的开放的顶端在以下位置之间移动：
-静止位置，在该静止位置处所述砧座设置在套筒的外部；和
-操作位置，在该操作位置处所述砧座设置在套筒内。
所述超声波发生器基本上包括：
-头部，其限定所述超声波发生器的密封表面，其接收所述开口装置的颈部和盖；和
-一个或多个驱动装置，其包括交替的压电陶瓷板和导电金属片的叠堆。
驱动装置耦合到交流发电机。以这种方式，压电陶瓷板将供电电压转换成机械应力，这导致头部的振荡，并且因此导致开口装置密封到包装的包装材料上。
此外，超声波发生器可通过包装的孔在以下位置之间移动：
-静止位置，在该静止位置，所述超声波发生器设置在套筒的外部；和
-操作位置，在该操作位置，开口装置接合套筒的孔。
超声波发生器和砧座的运动与开口套筒的运动同步。
特别地，当超声波发生器和砧座都处于相应的操作位置时，超声波发生器的头部被压靠在砧座上，以便将开口装置保持在相对于套筒的围绕孔的包装材料的固定密封位置。
在该阶段，发电机被启动，以便将开口装置密封到套筒的围绕孔的包装材料。
申请人已经发现，开口装置在超声波发生器内部的正确定位对于将开口装置有效地密封到相应的开口套筒是非常关键的。
更详细地，申请人已经发现，如果开口装置没有正确地定位在超声波发生器内部，则存在超声波振动被传递到开口装置的盖而不是凸缘的风险，从而损害了开口装置的密封。
在工业中有确保开口装置在超声波发生器内部的适当定位的需求。
发明内容
本发明的一个目的是提供一种超声波发生器，其设计成满足上述要求中的至少一个。
根据本发明，如权利要求1所述的，提供了一种超声波发生器，其被设计为满足上述要求中的至少一个。
附图说明
将参照附图通过示例来描述本发明的优选的、非限制性的实施方式，其中：
图1是通过使用根据本发明的超声波发生器获得的密封包装的透视图；
图2至图6示出了根据本发明的包括超声波发生器的密封装置的操作循环的各个连续步骤；
图7是图6的步骤的放大图；
图8是图6和图7的另一放大图；和
图9和图10示出了图2至图6的密封装置的另外的部件，为了清楚起见移除了一些部件。
具体实施方式
图2至图6中的附图标记1总体上表示用于将多个开口装置4,4a施加到用于形成相应包装2的相应开口套筒6上的装置。
更详细地，每个开口装置4,4a被施加到在相应包装2的包装材料5中制成的孔3(图7和8)上。
包装材料5由热密封片材制成，其包括在两侧上覆盖有热密封塑料材料(例如，聚乙烯)层的纸材料层。在用于长期储存产品(例如UHT牛奶)的无菌包装2的情况下，包装材料包括阻氧材料层，例如铝箔，其叠加在最终形成包装2的与食品产品接触的内表面的一层或多层热密封塑性材料上。
包装2优选含有可倾倒食品产品，例如巴氏杀菌或UHT牛奶、果汁、酒等。
在施加开口装置4,4a之前，将包装材料5切割成坯料。坯料首先竖立以形成在其底端(未示出)处被密封的套筒6(图4至图6)，而顶端7仍然是开放的并且孔3(图7和图8)仍然是开放的。
在施加开口装置4,4a之后，通过其打开的顶端7用可倾倒产品填充套筒6，并且相应的顶端7被密封，以便完成相应的包装2的形成。
在所示的实施方式中，开口装置4,4a(图7和8)具有轴线A，并且基本上包括：
-凸缘8，以及
-沿着轴线A从凸缘8突出的颈部9；以及
-拧在颈部9上的盖10。
特别地，凸缘8的直径大于颈部9的直径。
开口装置4优选由聚乙烯制成。
孔3的直径小于凸缘8的直径并且大于颈部9的直径。
在通过装置1进行施加时，凸缘8(图7和图8)接触包装材料5的侧面5a，颈部9穿过孔3，并且盖10设置在包装材料5的与侧面5a相对的侧面5b上。
包装材料5的侧面5a限定包装2和套筒6的内侧，而侧面5b限定包装2和套筒6的外侧。
装置1包括(图2至6和9，10)：
-包含开口装置4,4a的箱(未示出)；
-进给装置25，其供给有开口装置4,4a，并且形成多个柱24(在所示的实施方式中为两个)，开口装置4,4a被施加在相应的套筒6上；
-框架26，其支撑多个(在所示的实施方式中为两个)砧座27；
-框架30，其支撑多个(在所示的实施方式中为两个)超声波发生器81；和
-另一进给装置40(仅部分地在图4至图6中示出)，其用于在施加开口装置4,4a之前将包装2朝向砧座27和超声波发生器81推进，并且用于在施加开口装置4,4a之后将已经被施加了开口装置4,4a到其上的包装2从砧座27和超声波发生器81移离。
参考图2至8，可以定义：
-方向Y，在所示的实施方式中是竖直的；
-方向X，其在所示的实施方式中与方向Y正交并且是水平的；以及
-方向Z，其与方向X，Y正交。
在所示的实施方式中，柱24平行于方向Y延伸。
框架26设置在进给装置25的一侧，超声波发生器81设置在进给装置25的下方。
更详细地，对于每个柱24，进给装置25包括：
-在所示实施方式中平行于方向Y且竖直地延伸的滑槽36；和
-排出装置37，其可平行于方向X朝向和远离相应的砧座27移动。
每个滑槽36包括框架，该框架被成形为使得每个柱24的最下面的开口装置4a在一侧并且沿着方向X面朝沿着方向X的相应的排出装置37。
此外，每个滑槽36的框架被成形，以便沿着方向X，Z牢固地容纳相应的柱24的其它开口装置4，并且允许开口装置4在重力作用下沿着方向Y下落。
每个排出装置37包括活塞38，活塞38可在缩回位置(图2和图4至图6)和伸出位置(图3)之间平行于方向X移动，在伸出位置，活塞38在框架26的相对侧并朝向相应的砧座27推动最下面的开口装置4a。
进给装置40平行于方向Y在以下位置之间往复运动：
-静止位置(未示出)，在该静止位置处套筒6从装置1分离；和
-施加位置(如图4至图7所示)，在该施加位置处，进给装置40进给套筒6(仅示出一个)给砧座27和超声波发生器81，该套筒6具有开放的相应的顶端7并且开口装置4,4a仍必须已在相应的孔3处被施加到该套筒6。
在所示的实施方式中，静止位置是沿方向Y的降低位置，施加位置是沿方向Y的升高位置。
砧座27可相对于框架26沿着方向X、Y移动。
每个砧座27特别地能够相对于框架26平行于方向X在以下位置之间移动：
-静止位置(图2和图4)，在该静止位置处，砧座27在相应的套筒6的外部，并且沿着方向X与相应的滑槽36和对应的最下面的开口装置4a间隔开；和
-装载位置(图3)，在该装载位置处，砧座27邻近滑槽36并且通过设置在伸出位置的相应的排出装置37接收最下面的开口装置4a。
此外，每个砧座27可相对于框架26平行于方向Y并且通过相应套筒6的顶端7在以下位置之间移动：
-静止位置(图4)；和
-(在图5所示的实施方式中下降了的)中间位置，在该中间位置处，砧座27在相应的套筒6内部并且沿着方向X与孔3分离。
每个砧座27可相对于框架26并平行于方向X在以下位置之间移动：
-中间位置；和
-操作位置(图6至图8)，在该操作位置处，砧座27在相应的套筒6内部并且将开口装置4a放置在孔3内。
框架26包括载体31，载体31可沿着方向Y移动到框架26的引导件上。
特别地，每个砧座27包括：
-臂28，在所示的实施方式中为L形，其可相对于载体31平行于方向X移动；和
-接收元件29，其由臂28承载并且在所示实施方式中适于通过抽吸动作来夹持相应柱24的最下面的开口装置4a并且将其沿着方向X、Y相对于框架26传送。
特别地，当每个砧座27(图3)处于静止位置时，接收元件29的轴线沿着方向Y与相应柱24的最下面的开口装置4a的轴线A对齐，并且在相对侧沿着方向X与排出装置37的活塞38的轴线对齐。
此外，每个砧座27从相应的静止位置到相应的装载位置(反之亦然)的运动与相应的进给装置37的活塞38在相应的缩回位置和相应的伸出位置之间的运动同步(反之亦然)。
特别地，当每个砧座27(图5)处于相应的装载位置时，相应的接收元件29从相应的排出装置37的设置在伸出位置的活塞38接收相应的柱24的最下面的开口装置4a。
不同的是，当每个砧座27(图4)处于相应的静止位置时，相应的接收元件29沿着方向X与最下面的开口装置4a和设置在缩回位置的活塞38的轴线A间隔开。
每个超声波发生器81可平行于方向X并相对于框架30在以下位置之间移动：
-静止位置(图2至5)，在该静止位置处，超声波发生器81与套筒7间隔开；和
-操作位置(图6和7)，在该操作位置处，超声波发生器81从相应的砧座27的接收元件29接收相应的最下面的开口装置4a，并且被操作以将接合孔3的开口装置4a密封到相应套筒6的在孔3处的包装材料5。
特别地，平行于方向Y、X的每个砧座27和平行于方向X的相应的超声波发生器81的运动与进给装置40平行于方向Y的运动同步。
更精确地，当每个砧座27从相应的静止位置移动到相应的装载位置(反之亦然)并且从相应的静止位置移动到相应的中间位置时，相应的超声波发生器81处于相应的静止位置，而进给装置40处于静止位置。
然后，当进给装置40处于施加位置(图6至图8)时，每个砧座27和相应的超声波发生器81同时到达相应的操作位置。
在该构造中，在将开口装置4a密封到围绕相应套筒6的孔3的包装材料5的期间，每个砧座27在插入孔3内的相应开口装置4a的凸缘8上施加反压力。
更详细地，每个超声波发生器81包括(图7至9)：
-主体84；
-相对于方向Y与主体84相对并且围绕轴线B平行于方向Y延伸的头部86；和
-插入头部86和主体84之间的连接件87。
参考图8和9，头部86在本体84的相对侧上并且朝向包装材料5的侧面5b限定密封表面89和开口88。
当相应的超声波发生器81和相应的砧座27处于相应的操作位置时，每个密封表面89接触包装材料5的侧面5b，以便将其密封在相应的开口装置4a的凸缘8上。
超声波发生器81包括围绕轴线B延伸的腔90，当开口装置4a插入腔90中时，轴线B与轴线A重合。
头部86根据已知的解决方案连接到驱动装置(未示出)。
超声波发生器81的驱动装置由交替的压电陶瓷板和导电金属片的叠层形成，并且耦合到交流发电机。以这种方式，压电陶瓷板将由交流发电机提供的电功率转换成机械应力，这导致头部86的振荡，并且因此将凸缘8密封到包装材料5的围绕相应套筒6的孔3的侧面5a。
当开口装置4通过相应砧座27的接收元件29插入孔3中时，腔90接收开口装置4。
特别地，腔90相对于轴线B由壁92环形地界定，并且相对于轴线B且在表面89的侧面上由开口88轴向地界定。
有利地，超声波发生器81包括由弹性体材料制成的环91，其在腔90内部分地突出并且适于使开口装置4a的中心轴线A居中在超声波发生器81的轴线B。
更详细地，环91装配到壁92并且在腔90内从壁92突出。
特别地，开口装置4的壁92和颈部9通过间隙100与轴线B径向分离(图7和图8)。
间隙100在开口89和环91之间轴向界定。
环91在轴线B的侧部通过壁95径向地界定，当环91不变形时，壁95从开口88朝向卷材3的侧面3b的相对侧延伸，呈锥形。
特别地，壁95朝向轴线B会聚，从开口88朝向表面89的相对侧延伸。
环91与开口装置4的盖10配合，并且适于使开口装置4相对于头部86居中。
当每个超声波发生器81的环91变形时(参见图8)，从开口88朝包装材料5的围绕孔3的侧面5b的相对侧延伸，壁95限定：
-相对于轴线B以第一角度成角度的部分93；和
-相对于轴线B以小于第一角度的第二角度成角度的部分94。
在所示的实施方式中，环91由弹性体材料制成，优选由热固性材料制成。
还更优选地，环91由商业上称为Cellasto的蜂窝状聚氨酯弹性体制成。
因此，环91有效地使开口装置4,4a的轴线A相对于超声波发生器81的开口88的轴线B居中，而不将超声波振动传递到盖10。
下面参考仅一个砧座27、仅一个对应的超声波发生器81、仅一个对应的开口装置4a以及仅一个相应的套筒6和包装2来描述装置1的操作。
此外，下文描述装置1的操作，其中砧座27和超声波发生器81处于相应的静止位置，并且进给装置40处于静止位置，如图2所示。
从该状态开始，排出装置37的活塞38平行于方向X并朝向伸出位置移动，同时砧座27平行于方向X并朝向斜槽36(即，图3中的右侧)从静止位置移动到装载位置。
因此，在所示的实施方式中，最下面的开口装置4a从滑槽36移动到砧座27的接收元件29内部，砧座27的接收元件29通过真空动作夹紧开口装置4a。
在此处，砧座27平行于方向X朝向框架26向回移动，以再次到达静止位置(图4)，同时进给装置40到达施加位置并且向超声波发生器81和砧座27馈送具有打开的顶端7的套筒6。
在该阶段(图5)，砧座27平行于方向Y在所示实施方式中向下在中间位置移动。当砧座27平行于方向Y移动时，砧座27穿过套筒6的开口顶端7并沿着方向Y到达一位置，在该位置，接收元件29沿着方向X与孔3的轴线对准。
之后(图6)，砧座27平行于方向Y并朝向孔3(即在图6中的右侧)从中间位置移动到操作位置移动，而超声波发生器81平行于方向X从静止位置移动到操作位置。
当砧座27和超声波发生器81都处于相应的操作位置(图6至图8)时，开口装置4a接合孔3并且部分地容纳在超声波发生器81的腔90内。
更精确地，当砧座27和超声波发生器81都处于相应的操作位置时，开口装置4的颈部9和盖10进入腔90，盖10与环91的壁95协作，凸缘8接触包装材料5的围绕孔3的侧面5a，并且密封表面89接触包装2的包装材料5的侧面5a(图9)。
此外，盖10使环91的壁92变形，以便产生相对于超声波发生器81的头部86的轴线B不同地成角度的部分93,94(图9)。
以这种方式，环91有效地使开口装置4的轴线A居中在头部86的轴线B。
最终，当开口装置4的颈部9和盖10被容纳在超声波发生器81的腔90内时，在壁92和盖10之间产生间隙100(图7和8)。
在该阶段，超声波发生器81被激活并且头部86振荡，以便将开口装置4密封到套筒6的在孔3周围的包装材料5上。
一旦密封完成，超声波发生器81和砧座27回到相应的静止位置，并且供给装置40回到静止位置。
随后，以未示出的方式，密封套筒6的顶端7(已经对其施加了开口装置4a)，以便完成包装2的形成。
在该阶段，超声波发生器81沿方向X回到静止位置，砧座27沿方向X回到中间位置并且沿方向Y回到静止位置，并且循环再次重新开始。
根据本发明的装置1的优点从前面的描述将是清楚的。
特别地，由弹性体材料制成的环91在使开口装置4a居中在相应的声波发生器81的腔90内部时是有效率的，而不将超声波振动传递到盖10，因此不影响开口装置4a密封到孔3周围的包装材料5上。
环91是锥形的并且在开口88和表面89的相对侧上具有锥度(taper)。
以这种方式，环91和相应的盖10之间的接触面积特别小。
最后，由于间隙100的存在，仅超声波发生器81的表面89接触开口装置4a。因此，由于间隙100的存在，超声波发生器81的机械振荡被正确地传递到开口装置4a的凸缘8，而没有无用的传递到开口装置4a的颈部7和盖10。
显然，可以对超声波发生器81进行改变，而不脱离所附权利要求中限定的保护范围。
特别地，超声波发生器81可以用于将预成形的开口装置4施加到包装材料卷材上，该卷材将被折叠成管，横向热密封和横向切割以形成多个密封包装。
