Description

熔融树脂供给设备
技术领域
本发明涉及一种熔融树脂供给设备，该熔融树脂供给设备被设计成用于使从挤出机挤出的预定量的熔融树脂落入到压缩成型机中的阴模。
背景技术
作为饮料用容器，由诸如聚酯或聚对苯二甲酸乙二醇酯(PET)等合成树脂制成的合成树脂容器已经被广泛地投入实际使用。可以使用压缩成型机通过压缩成型一体地形成将通过吹塑成型形成为合成树脂容器的预成型体。在执行压缩成型时，熔融状态的合成树脂经由挤出喷嘴的开口被挤出，并且被树脂供给器供给到压缩成型机。
挤出机加热和熔融树脂材料并且从模头连续地挤出熔融树脂。熔融树脂根据加热温度产生乙醛或低聚物。沉积在PET瓶上的乙醛或低聚物对味道产生不利的影响。因此，挤出机在低温下挤出熔融树脂以抑制乙醛或低聚物的产生。
然而，即使在低温下挤出熔融树脂，也产生痕量(traceamount)的蒸汽状的乙醛或低聚物，并且蒸汽状的乙醛或低聚物在与保持单元接触时沉积在保持单元上。此外，熔融树脂(例如，树脂泡沫等)本身也可能经常粘附和沉积。
专利文献1：WO2005/102641
发明内容
发明要解决的问题
如果形成预定量的乙醛、低聚物和树脂泡沫(下文简称为低聚物)，则由于熔融树脂和保持单元的内表面之间的摩擦阻力，当熔融树脂落入压缩成型机的阴模中时，滑动性能降低，或由于导热性的降低而导致冷却不良。由于冷却不良而保持被高温加热的熔融树脂容易粘附到保持单元。因此，即使打开保持部件，熔融树脂也不会落下并且不能被供给到压缩成型机的金属模具中。为了避免这种不便，工人每隔几个小时就要清洁保持单元。然而，清洁沉积在保持单元上的物质的频率的增加影响缩短操作时间的极限并且使得难以提高生产率。
此外，即使在清洁操作过程中也从模头连续地挤出熔融树脂。因此，清洁操作时间的增加造成了熔融树脂的损失的增加。
上述专利文献1公开了作为用于防止物质沉积在保持单元(保持配件)上的对策的技术。该技术使用多孔材料并且允许来自外部的压缩气体经由多孔材料与熔融树脂接触。此外，根据需要，通过压缩气体使熔融树脂表面或熔融树脂保持部的内表面冷却，由此冷却保持单元中的熔融树脂保持部的内表面并且在冷却熔融树脂保持部的内表面时抑制粘附，然而，因为处理在密封的保持单元中完成，所以仍然不能充分地避免低聚物粘附到保持单元。
考虑到上述情况完成了本发明，本发明的目的是提供一种熔融树脂供给设备，该熔融树脂供给设备能够防止诸如低聚物等物质粘附到用于保持熔融树脂的保持单元上，并且能够缩短清洁保持单元的周期。
用于解决问题的方案
为了实现上述目的，本发明的熔融树脂供给设备包括保持单元，所述保持单元具有保持部，所述保持部能够开闭以保持从挤出机排出并且被刀具切断的熔融树脂，其中，所述保持部被打开以将所述熔融树脂投入到压缩成型机的阴模中，其中，保持所述熔融树脂的所述保持部的内周面有形成上下延伸的多个槽。
在该熔融树脂供给设备中，所述保持部设置有用于将气体吹到所述保持部的内周面和/或所述熔融树脂的表面的吹气部件。
在该熔融树脂供给设备中，形成于所述保持部的内周面的所述槽的截面为波形状。
在该熔融树脂供给设备中，在所述保持部保持所述熔融树脂的状态下，所述吹气部件将气体吹到所述保持部的内周面和所述熔融树脂。
在该熔融树脂供给设备中，所述保持部的内周面被处理过。
发明的效果
根据本发明，熔融树脂供给设备包括保持单元，保持单元具有保持部，所述保持部能够开闭以保持从挤出机排出并且被刀具切断的熔融树脂，其中，保持部被打开以将熔融树脂投入到压缩成型机的阴模中，其中，上下延伸的多个槽形成于保持熔融树脂的保持部的内周面。因此，在将熔融树脂投入到压缩成型机的阴模中时，熔融树脂保持面和熔融树脂之间的接触面积减小，并且改进了滑动性能。因为产生摩擦阻力的低聚物几乎不残留在保持单元上，所以熔融树脂能够平滑地落入阴模中。此外，还可以防止低聚物粘附和沉积在保持单元的熔融树脂保持面上，并且可以降低清洁频率。

图1是示意性示出用于形成被称为预成型体的诸如PET瓶或类似瓶等预成型物品的压缩成型设备的俯视图。
压缩成型设备1包括挤出机2、树脂供给器3、压缩成型机4、出口轮6和取出输送器7。
挤出机2具有大致筒状的外形，并且对诸如PET等合成树脂材料进行加热、熔融和捏和，并且将熔融树脂输送到齿轮泵8。齿轮泵8依靠齿轮的啮合而喷出保持稳定性的熔融树脂。齿轮泵8的喷出口经由到管道2a被连接到向下取向的模头10。模头10的截面为筒状，并且从大致筒状的模头10连续地向下挤出熔融状态的合成树脂。
图2是根据本发明的实施方式的树脂供给设备的放大俯视图，图3是树脂供给设备的主要部分的放大侧视图。
树脂供给设备3设置有刀具轮11。刀具轮11包括转动板12、摆动凸轮14、摆动单元15、伸缩单元(expansion unit)16和保持单元17。转动板12是盘状构件，并且具有在图中沿周缘保持相等角度间隔的6个摆动单元15，使得摆动单元15与转动板12一起转动。转动板12具有作为驱动部件的马达(未示出)，当从上侧观察时，转动板12沿顺时针方向转动。
摆动单元15在其下部具有凸轮从动件。当转动板12转动时，凸轮从动件摆动并且沿形成于摆动凸轮14的槽18移动。
伸缩单元16是基本上沿转动板12的径向延伸的棒状构件，并且伸缩单元16在其外周侧的末端部具有保持单元17。伸缩单元16以沿摆动单元15的长度方向往复移动的方式经由直线轴承等被设置于摆动单元15的上部。例如，由于气缸、凸轮、弹簧或马达或它们的组合(未示出)，伸缩单元16基本上沿转动板12的径向往复移动。
由于摆动单元15的摆动运动和伸缩单元16的往复运动，在操作时，保持单元17沿轨迹19转动，并且在将熔融树脂移交到压缩成型机4的金属模具51之前和之后，保持单元17沿金属模具51的转动轨迹20移动。因此，即使在高速操作时，也能够可靠地移交熔融树脂。
图4示出了保持单元的主要部分，其中，A是保持单元被闭合的状态的俯视图，B是保持单元的右侧视图，C是保持单元的后视图，D是保持单元被打开的状态的俯视图。
保持单元17包括基部21、一对保持件22和23以及刀具28。更具体地，基部21具有形成于其中的半圆形收纳凹部24以及形成于基部21的上部的沿转动方向向上倾斜突出的刀具28。基部21具有保持件22和23，其中，保持件22和23被可自由转动地被安装，因此，能够自由地开闭保持件22和23。保持件22和23能够被诸如转动致动器或凸轮机构等转动装置致动，并且在模头10的上游被打开，并且在刚经过模头10之后被闭合。在保持件22和23的闭合状态下，保持件22和23收纳凹部25，收纳凹部25与基部21中的收纳凹部24一起保持被刀具28切断的熔融树脂。保持单元17在保持件22和23被闭合的状态下输送被切断的熔融树脂。当保持单元17到达金属模具51的上方时，保持单元17打开保持件22和23以使熔融树脂落入下方的金属模具51中。
图5是沿基部21和一对保持件22和23中的槽31的水平方向的剖视图。
如图所示，横截面为波形状并且由凹部31a和凸部31b构成的纵向槽31形成在包括基部21的内周面的收纳凹部24和包括保持件22和23的内周面的收纳凹部25中。
这里，如果用于保持熔融树脂9的收纳凹部24和25具有图5所示的基圆30的尺寸，则凹部31a和凸部31b中的凸部31b以其端部沿如图5C所示的基圆30配置的方式定位。期望的是凸部31b与熔融树脂9接触的宽度(周长)L1为0.1mm至3mm。期望的是凸部31b被设置成超过收纳凹部24的周长或超过收纳凹部25的周长的10％至50％，或更优选地，期望的是凸部31b被设置成超过收纳凹部25的周长的10％至30％。
此外，期望的是凹部31a从基圆30开始的最大深度d为0.3mm至3mm。在凹部31a和凸部31b中，期望的是不与熔融树脂9接触的部分的宽度(部分的周向宽度)L2是1mm至5mm。
此外，期望的是凹部31a至另一凹部31a(或凸部31b至另一凸部31b)的配置具有1mm至15mm的节距P。
该实施方式中的凹部31a和凸部31b具有曲线形状的波形状，但是也可以形成为矩形或三角形。凹部31a和凸部31b形成为在圆周方向上维持相等的角度间隔。然而，凹部31a和凸部31b不是必须形成为维持相等的角度间隔，基部21中的凹部31a和凸部31b之间的间隔可以与保持件22和23中的凹部31a和凸部31b之间的间隔不同。
期望的是以使低聚物不粘附在收纳凹部24和25的表面上的方式处理用于保持熔融树脂9的收纳凹部24和25的表面。在该实施方式中，已经实施了iepco处理或氟涂覆(fluorinecoating)。
图6A至图6C示出了纵向槽31的形成位置。图6A至图6C示出了基部21中的收纳凹部24。对于一对保持件22和23，纵向槽31的形成位置与基部21的纵向槽31的形成位置相同，或者与如下所述的不同模式的纵向槽的配置组合来形成纵向槽31。
在图6A中，在基部21的收纳凹部24的上部至中部没有形成纵向槽31，而是在收纳凹部24的下部形成纵向槽31。在图6B中，在收纳凹部24的下部没有形成纵向槽31，而是在收纳凹部24的上端经过中部向下至下部形成纵向槽31。图6C是在从上端至下端的整个收纳凹部24中形成纵向槽31的情况。此外，虽然未示出，但是纵向槽31可以只形成于收纳凹部24的沿上下方向的中部。在该情况下，如果纵向槽31形成为比熔融树脂9的整个高度长，则使得低聚物经由纵向槽31的下侧(或取决于保持熔融树脂9的位置经由纵向槽31的上侧)溢出保持单元17，这是期望的。此外，纵向槽31可被形成于收纳凹部24的除了中部之外的上部和下部。
参考图6A和其它附图，期望未形成纵向槽31的区域被选定为熔融树脂9的整个高度+熔融树脂9的整个高度的10％。这是因为，即使在高速操作熔融树脂供给设备1之后通过刀具切断从模头10挤出的树脂并且之后熔融树脂9由基部21支撑，由于熔融树脂9与纵向槽31压力接触(press-contact)，在熔融树脂9上没有留下槽痕。
在图6D中，纵向槽31形成在与图6A所示的纵向槽31的位置相同的位置。在收纳凹部24的没有形成纵向槽31的上部和中部中，形成气体喷出孔34。喷出孔34与贯通基部21的内壁的流路36连通，其中，流路36经由管路38被连接到未示出的气体喷出部件37(参见图5A)。气体喷出部件37使用诸如氮气等惰性气体或压缩惰性气体以及诸如空气等气体或压缩气体。
可以以多种方式设定喷出孔34的方向(气体喷出方向)，诸如与收纳凹部24垂直或与收纳凹部24成预定角度等。然而，如果试图使气体沿如图5A所示的熔融树脂9的周向流动，则期望气体流经熔融树脂9的整个圆周。
在图6E中，纵向槽31形成于与图6C所示的纵向槽31的的位置相同的位置。气体喷出孔34也可以形成于形成纵向槽31的部分。此时，气体喷出孔34可以形成在收纳凹部24的凸部31b侧。然而，因为熔融树脂9几乎不妨碍气体的流动并且气体容易沿基部21的上下方向流动，因此，如图5A所示，气体喷出孔34形成于凹部31a是更好的。此外，纵向槽31可以具有配置于基部21的上部或基部21的下部的喷嘴。此外，可以适当地增加喷嘴的数量。喷嘴还可以被设置于保持件22和23。
图7A示出了保持单元17被输送到腔模52的正上方的状态。
压缩成型机4被设置成以使多个腔模52连续地在圆形轨迹上移动的方式转动(参见图1)。如图7所示，腔模52在其上部开口，在腔模52的上方，以可相对于腔模52上下移动的方式设置作为上模的颈部半模(neck halves)53。
在熔融树脂9的移交位置，保持单元17被配置于颈部半模53和腔模52之间，使得在打开保持件22和23时，熔融树脂9能够被供给到腔模52的内孔54中。参考图7B，在熔融树脂9被供给到腔模52之后，保持单元17离开压缩成型机4的转动轨迹20(参见图2)。
颈部半模53由在水平方向上开闭的左右一对模具形成，并且上下移动的芯轴55被配置于腔模52的上侧。芯轴55被推入到颈部半模53的通孔53a和腔模52的内孔54中，从而将熔融树脂9压缩成型为预成型体。
参考图1，出口轮6被布置于压缩成型机4的下游，以取出预成型体。出口轮6具有用于将预成型体输送到下一个步骤的取出输送器7。
接着，以下将说明根据本发明的实施方式的树脂供给设备的作用。
挤出机2对诸如聚对苯二甲酸乙二醇酯等合成树脂材料进行加热、熔融和捏和，并且将熔融树脂9输送到齿轮泵8。为了稳定地供给熔融树脂9，齿轮泵8被构造成通过齿轮的啮合喷出熔融树脂9。齿轮泵8经由管道2a将熔融树脂输送到图2所示的向下取向的模头10。模头10通过形成于其下端部的挤出口连续地向下挤出形成为大致柱状的熔融树脂9。
通过刀具28切断被挤出的熔融树脂9，并且从挤出口切离熔融树脂9。在闭合保持单元17的保持件22和23时，被切离的熔融树脂9被保持在收纳凹部24和25中。在从模头10喷出熔融树脂9时，熔融树脂9产生蒸汽状的乙醛或低聚物。因此，在闭合保持件22和23之前，气体被从喷出孔34喷出。在喷出气体时，能够将低聚物从保持单元17吹出，同时，冷却用于保持熔融树脂9的收纳凹部24和25，因此，冷却熔融树脂9的表面。
在如上所述地冷却收纳凹部24和25的内表面以及熔融树脂的表面时，熔融树脂9几乎不粘附到收纳凹部24和25的内表面。
因为由凹部31a和凸部31b在熔融树脂9以及收纳凹部24和25之间形成间隙，因此，由保持单元17保持的熔融树脂9允许低聚物从间隙的上端或下端溢出。此外，在凹部31a中形成喷出孔34时，从喷出孔34中喷出的气体流过纵向槽31和熔融树脂9之间的间隙。经由所述间隙，能够将熔融树脂9被输送时保持单元17中产生的低聚物被排出到外部。
保持单元17在保持熔融树脂9的同时在圆形轨迹上移动。在保持单元17刚好移动到压缩成型机4的腔模52的正上方之后，如图7A所示，保持单元17进入腔模52和颈部半模53之间。也就是，当保持单元17、腔模52和颈部半模53的轨迹刚好移动到同一轨迹32(参见图2)时，保持单元17的保持件22和23被打开，并且熔融树脂9从保持单元17被供给到模腔52的内孔54中。
这里，因为保持单元17的收纳凹部24和25中形成纵向槽31，因此，收纳凹部24、25的内表面与熔融树脂之间的接触面积减小。因此，熔融树脂9呈现出改进的滑动性能并且能够有效地落入内孔54中。具有粘附在收纳凹部24和25的内表面上的性能的蒸汽状的低聚物经由纵向槽31的间隙被排出到外部，并且几乎不粘附在收纳凹部24和25上。
在如上所述地防止上述低聚物的粘附时，可以避免以下不便：不管保持单元17是否打开，熔融树脂均不落下；以及熔融树脂没有被供给到压缩成型机的金属模具中。此外，即使低聚物已经粘附，也可以减少低聚物的粘附量并且可以延长需要实施清洁之前的时间，提供减少熔融树脂的损失的效果。
参考图7C，颈部半模53向下移动并且被配置在腔模52上。其后，芯轴55向下移动并且进入通孔53a和内孔54中。
参考图7D，形成具有与待形成的预成型体27的形状相同形状的间隙，并且熔融树脂9填充内孔54和颈部半模53侧的间隙。由于熔融树脂9被芯轴55压缩，因此，熔融树脂9形成预成型体27。
在已经形成预成型体27之后，在预成型体27被冷却的同时，如图1所示，由于腔模52的运动，预成型体27接近出口轮6的把手35的圆形轨迹。其后，颈部半模53和芯轴55在支撑预成型体27的状态下向上移动，预成型体27被从腔模52取出，被传输到取出输送器7并且在下一个步骤中被输送到吹塑成型生产线(forming line)上。
当通过吹塑成型形成容器时，预成型体27不产生乙醛或低聚物，并且不对饮料的味道产生不利影响。
虽然上面已经借助于实施方式说明了本发明，但是应该注意的是当然可以基于本发明的技术构思以各种方式对本发明进行进一步地变型或修改。
例如，纵向槽31可以是倾斜到不妨碍熔融树脂9落下的程度的螺旋形状。
此外，刀具28可以不被设置在保持单元17上，而是可以分开设置，例如，刀具28可被设置于挤出机2的模头10的下方。
此外，设备不限于连续地转动多个保持单元17和金属模具的情况，也可以是使用单个保持单元17和单个金属模具的情况或直线输送类型的情况。
