Description

折合包装容器的底封装置及工艺 技术领域
本发明涉及饮品的折合包装容器的底封装置及工艺，以涉及液体饮品为佳。
背景技术
折合包装容器例如复合纸(纸浆、铝或锡纸)包装容器等，被广泛应用于液体(水、奶、果汁、药液等)等包装，其包括至少两层，一般采用多层复合而成，其内壁层具有防渗漏材料(例如食品级塑料)，同时具有受热后可以自行热熔粘接为一体，而中层或外侧的复合纸材具有折合后良好定型效果。
但是现有技术在灌装之后，需要一端封口(一般是底部，如果侧部为等同)，现有技术的侧封部进行粘接，侧向折合后粘接；然后，将其位于另一面(例如底封或顶封)进行对合粘接为一体，折耳并粘接，由于底部与侧部对合部(也叫缝合线、封合线、密封线)均在一条竖直面上，由此会造成之后对其进行侧向翻转90°，会出现因为应力集中、存在折角等，使得容器产生形变，密封不严实，废品率高，同时，因为存在中间侧边封，使得容器站立不平稳，需要将底部进行定型，使得底部中心上凹，工艺复杂。
目前，底封工艺不合理，容易产生渗漏或变形，薄厚不均匀现象。
为了解决上述技术问题，目前也有将底部进行内外面搭接后采用PP/PE条或胶条粘接，从而影响饮品的卫生与健康。

具体实施方式
如图1-9所示，本实施例的折合包装容器的底封装置，用于对折合包装体1底部进行折合的底封组件90，其可以安装在地面上，载台上或其他位置。底封组件90包括底封机架91，其形状不附图限制，可以是L型，笼体，龙门型等常规件；在底封机架91上设置有工位更换架92，可以为整体由推杆或机械手等操控，方便更换，提高效率，也可以采用人工更换；本发明可以多列操作。
在工位更换架92上设置有若干仿形套体93，优选为四方内孔，从而方便更 换；
在底封机架91中设置有第一侧推夹持臂98及第二侧推夹持臂99，其模拟人手实现底部折合，可以是两臂活动设置或一臂固定一臂活动，优选采用直角结构，从而方便一次成型；
在底封机架91中设置有底封工位100；在底封工位100，第一侧推夹持臂98及第二侧推夹持臂99对合夹持折合包装体1的底部密封部成形；从而实现了折合成型。
在底封工位100上方升降有第七下插板107，第七下插板107用于下压折合包装体1内侧壁，使得折合包装体1底部开口变扁，作为一个创新点，解决了现在折合时，其出现反向折合而产生废品的问题。
作为下插板驱动方式，可以曲轴连杆或推杆等，作为优选，本发明采用了连杆机构，在底封机架91上方设置有动力驱动的第一驱动摆动臂101，在底封机架91上设置有第二转动杆102，第一驱动摆动臂101端部与第二转动杆102铰接，在第二转动杆102上键连接有第三联动臂103的根部，在底封机架91中设置有第五直立杆104，在第三联动臂103端部通过第四铰接臂105铰接有第六压板106，第七下插板107设置在第六压板106下表面上；第六压板106具有穿过第五直立杆104的导向孔，从而实现连续导向驱动。
仿形套体93横截面为四方孔、六方孔或八方孔等方式或其变形；
仿形套体93的上端进口具有上导向喇叭口94，方便导入，同时方便折合定型；
仿形套体93的下部侧面具有下工艺豁口95，从而取出，减少行程中的摩擦力。
在底封机架91侧壁上设置有对合气缸96，对合气缸96牵动有往复推动杆97，其为优选，可以采用其他直线往复方式。
作为实施例，第一侧推夹持臂98与第二侧推夹持臂99分别连接对应的往复推动杆97或第一侧推夹持臂98连接有对应的往复推动杆97且第二侧推夹持臂99固定设置。
第七下插板107前端具有倒角，从而实现仿形，从而使得底部开口更好的向两侧张开变成鸭嘴状，同时，利用倒角压在斜面上，从而更好的张开与定型。
在底封工位100设置有焊接机或第一侧推夹持臂98及第二侧推夹持臂99 作为热合头；
第一侧推夹持臂98及第二侧推夹持臂99分别具有呈直角的竖直面及水平面，竖直面与底部密封处外侧壁接触，用于下压底面成形。
工位更换架92可拆卸或固定设置；仿形套体93可拆卸或固定设置，从而配套自动化控制，针对不同规格包装容器，更换不同的模具工装套体。
作为针对附图配套描述，针对折合包装体1，其与第七下插板107对应接触的折合包装体1内侧壁对应第一底折耳折合面18及第二底折耳折合面19；
底部密封处对应第一底封部I26、第二底封部I27、第一底封部II28及第二底封部II29形成的底封部10，底面对应底部5，从而便于理解本发明装置的作用。
本实施例的折合包装容器的底封工艺，执行以下步骤；首先，待底部折合的折合包装体1放入到仿形套体93；然后，在底封工位100，第七下插板107下压折合包装体1内侧壁，使得折合包装体1底部开口变扁；其次，第一侧推夹持臂98与第二侧推夹持臂99对压折合包装体1，使得折合包装体1底部密封处贴合成形及底面下压成形，从而完成自动化底封折合，实现侧封部与底封部错开，从而密封性好。
如图1-9所示，本实施例的折合包装容器结构，包括折合包装体1，当折合后形成用于容纳载物的空腔；载物一般为液体，但包装颗粒物或固体也是本发明的保护范围。其中，
上部开口，如图4、5，位于折合包装体1之上，且至少在空腔载物(例如灌装液体或存放固体)之后在上部开口具有瓶盖4；一般在灌装液体之前安装为佳，避免二次污染，对应上部开口的容器，例如纸杯，瓶盖4可以不需要或根据需求选择是否安装。如果将上部开口变为侧部或底部也是本发明的保护范围。如果将上部开口采用其他方式(例如贴膜、糊盒或折合)进行密封，但是在通过对载物空腔上部进行切割后，仍然会露出上部开口的，同样是保护范围。作为本发明的保护范围，如果将在侧面或正面(背面)开口作为侧开口来规避上开口，同样是本发明的等同。将本发明的底部与上部调换，或将放置方式进行调换均是保护范围。再者，将任表面进行改为平面或立体形状均是保护范围。
底部5，与上部开口相对；作为底部，实现支撑容器的作用。
对折部A2与对折部B3，其对接折合；对折部A2的正表面部13与对折部B3 的正表面部13作为折合包装体1的对应正面(也可以认为一个正面，一个背面)且位于底部5与上部开口之间；在正面之间至少设置有位于底部5与上部开口之间的第一侧面与第二侧面；
空腔位于底部5、上部开口、对折部A2、对折部B3、第一侧面及第二侧面之中；即优选为四棱柱结构，但不限于四棱柱结构，例如多棱柱或其他至少具有上下部及四个侧面的容器结构。
本发明至少包括以下方案之一或其合理组合；
a)，如图4、5，第一侧封部6与第二侧封部7，作为对折部A2与对折部B3对合后的侧面密封部，第一侧封部6与第一侧面外侧粘接方向相反于第二侧封部7与第二侧面外侧粘接方向，这是本发明的重要发明点，其解决了传统如图1折合方式及本发明改进前图2存在的技术问题，例如底部密封不严实，交叉处焊接工艺性差，受力不均衡，使得容器形状容易产生形变，如图1这个均在一个平面上，容易产生泄露，而且放置与码垛不方便，不稳定，省去了粘接条30，更加安全卫生，实现直接封合，减少了容器的外形尺寸，使得容器更加规整。但是，如果为了规避本发明而增加粘接条30，是本发明的保护范围。
b)，当第一侧封部6与对折部A2外侧壁粘接时，第二侧封部7与对折部B3外侧壁粘接；其为方案a)的说明。
c)，底折耳A8，其根部与对折部A2的正表面部13下部连接且在连接处具有折痕线CD；底折耳B9，其根部与对折部B3的正表面部13下部连接且在连接处具有与折痕线CD平行的第一折痕线；从而实现底部的折合。
d)，底封部10，作为对折部A2与对折部B3对合后的底面密封部；底封部10与第一侧封部6不共面和/或底封部10与第二侧封部7不共面；作为本发明又一个主要发明点，从而解决了如图1方案存在的底部折耳对合相互干涉的问题，受力更加合理，成形更加稳定。
e)，在第一侧面处，在对折部A2内侧壁与对折部B3之间存在成形内凹A68，在第二侧面处，在对折部A2内侧壁与对折部B3之间存在与成形内凹A68相交错的成形内凹B69；作为本发明又一个主要发明点，从而实现底部封合的时候，相互适配，从而具有更好的密封性，工艺性好，厚度均匀，外形规整。
f)，底封部10对合面垂直于第一侧封部6对合面和/或第二侧封部7对合面；
g)，上部开口至少在空腔载物之后在上部开口具有瓶盖；
h)，第一侧封部的密封处理与第二侧封部的密封同时或分别进行。
折痕线CD与第一折痕线为底部5的边缘线；
本发明中的折合线，折痕线是同一意思，可以连续线，断线，折合线可以对应的面的延伸虚拟线，肉眼可看见可看不见，线可以具有共同端点的多分支的多线段，可以是合理变形的曲线等。
第一上折耳12，位于第一侧面上部，第二顶折耳11，位于第二侧面上部；在折合包装体1的展开状态上，折痕线CD分别与第一上折耳12根部折痕线VW或第二顶折耳11根部折痕线XY垂直或斜交(优选为垂直)，第一折痕线分别与第一上折耳12根部折痕线VW或第二顶折耳11根部折痕线XY垂直或斜交。作为本发明又一个主要发明点，从而实现底部封合的时候，相互适配，从而具有更好的密封性，工艺性好，厚度均匀，外形规整。

第二变向侧封I23，通过折痕线EF与第二侧封部17连接且通过折痕线EL与第二底部表面21连接并折合后到底部5，折合后，对折部A2的第二变向侧封I23与对折部B3的第二变向侧封I23粘接形成底封部10的一部分；
第一再向侧封II24，通过折痕线GH与第一变向侧封I22，折合后，对折部A2的第一再向侧封II24与对折部B3的第一再向侧封II24粘接形成底封部10与第一侧封部6的第一连接部；
