Abstract

红外线熔敷机具有用于通过红外线来将树脂制的第一构件的端面和树脂制的第二构件的端面中的至少任一方(称为加热对象面)加热、熔融的加热装置。加热装置具备:截面圆形的灯,被配置为与所述加热对象面非接触地对置且向径向朝外的全方位辐射红外线;上侧反射构件,以使从灯向所述加热对象面的上侧辐射的红外线趋向所述加热对象面的方式进行反射;以及下侧反射构件,以使从灯向所述加热对象面的下侧辐射的红外线趋向所述加热对象面的方式进行反射。

Description

红外线熔敷机
技术领域
本发明涉及用于将树脂制的第一构件、第二构件的端面彼此接合的红外线熔敷机。
背景技术
例如日本特表平09-502405所示的对接焊接装置配置为:通过分别用加热装置将两个塑料管的各端面加热熔融并且将所述端面彼此对接并加压来进行接合。
所述加热装置具有:由具有耐热性和电绝缘性的圆板构成的固定板;装配于该固定板的两面的螺旋状或环状的电阻加热元件;以及包覆所述固定板和所述电阻加热元件的筒状壳体元件和防护板。
所述电阻加热元件平坦地形成,此外,所述防护板由红外线透过性的玻璃陶瓷形成。
此外,日本专利第5768469所示的塑料容器的密封方法如下:通过红外线加热器将容器主体的接合面或盖构件的接合面加热熔融,通过将所述盖构件的接合面载置于所述容器主体的接合面来使其相熔而进行接合。
并且,记载了用反射构件使从所述红外线加热器辐射的红外线聚光于加热对象面的一点,此外,记载了用反射构件将从所述红外线加热器辐射的红外线调整为平行从而使其呈均匀面状照射至加热对象面。
在上述日本特表平09-502405中,仅有从所述电阻加热元件与所述各端面正对的区域辐射的红外线照射至所述各端面,在从所述电阻加热元件辐射的红外线中存在未照射至各端面的红外线,因此,加热效率差,使所述各端面的整个区域加热熔融所需的时间恐怕会变长。
另一方面,在上述日本专利第5768469中使所述红外线聚光于一点的情况下,使红外线照射至所述接合面的整个区域所需的时间恐怕会变长。
此外,在上述日本专利第5768469中使所述红外线平行照射的情况下,每单位面积的加热能量变低,因此将所述接合面的整个区域加热熔融所需的时间恐怕会变长。
发明内容
鉴于这样的情形,本发明的目的在于提供一种能均匀且迅速地将加热对象面的整个区域熔融的红外线熔敷机。

在此,例如如图3所示,在第二单元7c、8c中,第二外径侧反射构件76、86与第二灯75、85的外径侧间隔规定尺寸a地配置,第二内径侧反射构件77、87与第二灯75、85的内径侧间隔规定尺寸b地配置。在此,所述间隔尺寸a、b被设为相同。
虽然未进行图示,但与上述同样地,在第一单元7b、8b中,第一外径侧反射构件72、82与第一灯71、81的外径侧间隔规定尺寸地配置,第一内径侧反射构件73、83与第一灯71、81的内径侧间隔规定尺寸地配置。在此,所述间隔尺寸也与所述间隔尺寸a、b同样地被设为相同。
接着,对使用上述的红外线熔敷机1来将第一套管2b和第二套管2c接合于中央管2a时的顺序和动作进行说明。
首先,如图1所示,使中央管2a、第一套管2b、第二套管2c以配置于同一轴线上的方式支承于夹紧件3a~3f,使中央管2a的左侧(一端侧)的环状端面与第一套管2b的环状端面分离规定尺寸地相对,并且使中央管2a的右侧(另一端侧)的环状端面与第二套管2c的环状端面分离规定尺寸地相对。
然后,通过左侧的升降单元9来使左侧的加热装置7配置于中央管2a的左侧的环状端面与第一套管2b的环状端面的对置空间(照射位置),并且通过右侧的升降单元10来使右侧的加热装置8配置于中央管2a的右侧的环状端面与第二套管2c的环状端面的对置空间(照射位置)。
此时,第一单元7b、8b的各元件(71~73、81~83)与接合对象(2b、2a)的加热对象面的相对位置关系以及第二单元7c、8c的各元件(75~77、85~87)与接合对象(2a、2c)的加热对象面的相对位置关系被如图2和图3所示的那样设定。
在这样进行了准备之后,使红外线从两个加热装置7、8的第一灯71、81和第二灯75、85辐射。
此时,除了从第一灯71、81向径向朝外的全方位辐射的红外线中的朝向右半圆区域辐射的红外线被反射膜71a、81a朝向左半圆区域反射之外,从第一灯71、81朝向外径侧辐射的红外线被第一外径侧反射构件72、82朝向加热对象面反射,并且从第一灯71、81朝向内径侧辐射的红外线被第一内径侧反射构件73、83朝向加热对象面反射,因此从第一灯71、81辐射的红外线几乎全部被高效地聚集并呈均匀面状照射至加热对象面(第一套管2b的环状端面、中央管2a的右侧的环状端面)。
另一方面,除了从第二灯75、85向径向朝外的全方位辐射的红外线中的朝向左半圆区域辐射的红外线被反射膜75a、85a朝向右半圆区域反射之外,从第二灯75、85朝向外径侧辐射的红外线被第二外径侧反射构件76、86朝向加热对象面反射,并且从第二灯75、85朝向内径侧辐射的红外线被第二内径侧反射构件77、87朝向加热对象面反射,因此从第二灯75、85辐射的红外线几乎全部被高效地聚集并呈均匀面状照射至加热对象面(中央管2a的左侧的环状端面、第二套管2c的环状端面)。
若执行规定时间这样的加热、熔融,则能抑制所述各环状端面中的径向的中间区域的熔融深度与径向的一端侧区域和另一端侧区域的熔融深度的偏差。
在经过所述规定时间后,通过升降单元9、10来使加热装置7、8下降,由此使加热装置7、8配置于退避位置。
接着,在通过滑动件4来使第一套管2b、中央管2a、第二套管2c移动从而推压至承接台5之后,通过加压源6来将第一套管2b的环状端面按压至中央管2a的左侧的环状端面,并且将中央管2a的右侧的环状端面按压至第二套管2c的环状端面。
由此,成为第一套管2b的环状端面被接合于中央管2a的左侧(一端侧)的环状端面,并且第二套管2c的环状端面被接合于中央管2a的右侧(另一端侧)的环状端面,得到中空容器2。
以上那样的操作中的各条件(抵接速度、加压压力、加压时间等)优选适当调整为在经验上掌握的最佳值。
如以上说明的那样,根据应用了本发明的实施方式,能通过第一灯71、81的反射膜71a、81a、第一外径侧反射构件72、82以及第一内径侧反射构件73、83来将从第一灯71、81向径向朝外的全方位辐射的红外线高效地聚集并使其呈均匀面状照射至接合对象(中央管2a、第一套管2b、第二套管2c)的加热对象面(各环状端面)。
另一方面,能通过第二灯75、85的反射膜75a、85a、第二外径侧反射构件76、86以及第二内径侧反射构件77、87来将从第二灯75、85向径向朝外的全方位辐射的红外线高效地聚集并使其呈均匀面状照射至所述接合对象的加热对象面。
由此,能抑制所述加热对象面中的中间区域的熔融深度与一端侧区域和另一端侧区域的熔融深度的偏差,因此,当在所述熔融后将所述接合对象的加热对象面彼此对接并加压时,所述加热对象面的整个区域会被均匀地接合。
因此,能提高所述接合对象(中央管2a、第一套管2b、第二套管2c)的接合强度,并且能缩短所述加热熔融所需的时间。与此相伴,能缩短接合所需的时间。
需要说明的是,本发明并不限定于上述实施方式,可以在权利要求书的范围内以及与该范围等同的范围内适当地进行变更。
