Description

本发明涉及一种在管件绝缘层中铺设金属箔衬的方法,绝缘层的主要含有矿物纤维,而金属箔有粘合剂涂层,可受热活化,管绝缘层和一个被驱动的轴向平行加热辊配合,而金属箔在加热辊的横向上,向管绝缘层和加热辊之间供给。还涉及一种生态环境实现这方法的设备,该设备包括有管绝缘层装载工位;卷绕绝缘层的装置;加衬工位其中有可的加热辊,使金属箔上的粘合剂活化;横向放置在加衬工们下的供箔装置。
以上前言中所述的方法,已刷专利第DAS2,  416,  471号公布。所涉及的这已知方法,是用一个设备铺设管绝缘层,设备有两个相邻平行放置的可驱动辊,支持管绝缘层并使之旋转。与这些辊迳直相对的,在本设备还有一个加压装置,按照辊的圆周速度被驱动,可在工作位置和后退的装卸料位置之间移动,用于把管绝缘层向辊压紧,金属箔由进料装置在辊件的横向上供料。为了使金属箔粘合剂活化,还要求把邻近金属箔供料装置的辊制造成为加热辊。
所涉的这已知设备,运转时把一个无缝裸管绝缘层,用链式输送器在两个辊和后退的加压装置之间轴向推送,然后加压装置向下移动,直到贴靠绝缘层。然后,具有两个旋转加压带的加压装置,和两个辊被分别驱动,使浮置的管绝缘层旋转。同时,把预先准备好的一段金属箔横向引入,放在加热辊和管绝缘层之间。当金属箔向加热辊上送去,加热辊受热,直到粘合剂可作粘合。同时,金属箔被加热辊向绝热层加压,在绝缘上面缠绕,实际上直到管绝缘层旋转1.25周。按这方法加衬,于是一旦加压装置又离开,便把管绝缘层用上文已提到的链式输送器,从加衬工位上轴向撤去。
但是,这种已知的加衬方法,仅适用于无缝管绝缘层,因为这种绝缘层有基本无尽头的外表面,仅需把它在金属箔上缠绕。在这种情况下,毋需为了使金属箔和绝缘层纵向槽孔边边缘准确比齐,而把管绝缘层精确定位。即使放在加热辊和管绝缘层之间的金属箔没有能被正确牵引,也就是没有放在准确的平行位置上,或者,开始粘合时有缺陷,那么仍然可以取得外观完善的产品,因为在金属箔的起点端部耻被一个金属箔部分搭接,其长度相当于管绝缘层旋转的四分之一周。而且,这设备有一个相当长的步进运转时间,因为,直到能把未加衬的管绝缘层再推到辊件上面作加衬以后,才能把已加衬的绝缘层从设备中取出。
相比之下,本发明课题是以改进上述前言中的方法,并以改进适合于实现这方法的设备为基础,可以在全部纵向切缝管绝缘层上,在尽可能高的产速下,全自动地精确加金属箔衬,也就是配合绝缘衬的制造过程,保证在管绝缘层纵向切缝的两侧,同时准确固定金属箔,箔绝缘层的纵向切缝,最好是在紧接实际铺衬过程前产生。
本课题的解决是通过以下方法来获得的:
为了在开始时管绝缘层把金属箔精确引导,把金属箔放到预定位置上去,在这位置上很容易用一个相似轴向平行的导轨,把金属箔的自由端部向下弯折,处在准备的位置上,使箔的弯折端部放到可垂直调节的加热辊上,加热辊在起动位置上时,可以与管绝缘层的外表有一个小距离,这时箔上的粘合剂已开始活化,然后加热辊向管绝缘层(3)移动,在箔外缘接触管绝缘层外缘后,在一个短时间内保持该贴合位置,然后,加热辊和管绝缘层都被分别向相反方向驱动,并有相同的圆周速度,实际的加衬操作使开始。
为制作为切缝的管绝缘层,把一根未切缝的管绝缘层,有一根输送臂,连续向一根与卷轴同心放置的接受轴上推送,管绝缘层纵向切缝用切割装置形成,然后随着输送臂的连续向前的移动,把切缝后管绝缘层完全推到与接受轴同心放置的卷轴上去。
本发明优点之所以取得,具体在于因为金属箔粘合剂活化开始时,和最后的粘合阶段,放置中的管绝缘层可以保证把金属箔的头端精准引导,因此,一方面可能有相当高的铺衬速度,减短驻留时间,例如减至7秒钟,而另一方面,金属箔在纵向切缝的边缘区域牢固粘结,在安放管绝缘层时不会脱胶。
假如打算对已有切缝的管绝缘层进行加衬,那么,有利的做法是把绝缘层推送到一个卷轴上,卷轴与加热辊轴有平行的轴线,有在垂直下方的径向外伸导杆,并有驱动条插在管绝缘导以纵向切缝里,而同时,金属箔翻折的端部已处在备用位置上,其外级接近管绝缘层纵向切缝附近表面的一个想象伸展平面。金属箔处于这种备用位置,可保证在实际加衬过程开始前不久,已金属箔准确靠在纵向切缝的边缘上。
假如,为了实现完全连续的运转,可以把管绝缘层加衬过程配合其制造过程进行,然后,为了准备好切缝管绝缘层,采用一种方法,把一种所谓的绝缘层制造机制造的无缝管绝缘层,用一根输送臂连续推到与卷轴同心放置的一个接受轴上去,从而可用一个切割装置,在管绝缘层上形成纵向切缝。然后随着输送臂的连续向前的移动,把切缝后的绝缘层,完全扒送到与接受轴同心放置卷轴上去。
假如使用带自粘条的所谓悬垂口片,在实际加衬过程中,驱动加热辊和卷轴,直到加衬管绝缘层放置约340度到350度是有利的,然后加热辊在这位置上稍作停留,粘合封口,继而下降到起点位置上。加衬过程的这种中断,可保证悬垂封口不会粘在已经附在绝缘层上的金属箔上。
为实现上述方法,在本发明的设备中,装载工位有一个中心开缝的接受轴,用一个向接受轴移动的输送臂,把管绝缘层推向接受轴。设有切割装置,可在管绝缘层上切出一条连续的纵向切缝,切适到有中缝的接受轴中去。卷绕装置有可驱动的卷轴,可以用上述输送臂,把切编管绝缘层向卷轴上进一步推送,卷轴和接受轴同轴相邻,其端面和接受轴可用旋转的插头连接,并有径向伸出的引导件和驱动条,插入管绝缘层的纵向切缝中。加衬工位的可驱动加热辊,可调节其高度,旋转在卷轴的下方,与卷轴有平行的轴线。共箔装置有平行于加热辊轴向延伸的杆,围绕其轴旋转。
本发明的设备,一方面解决了提出的问题,而另一方面则可能操纵一条完全连续的生产线,利用这生产线还可能对任意批量的各种不同截面尺寸的管绝缘层加衬。适合不同截面尺寸是易于做到的,因为对不同内径范围的管绝缘层,可在料库中储备各种与相关尺寸一致的各种接受轴和卷轴,而管绝缘层的不同外径,可因加热辊高度可调而作补偿。
最后,为了达到生产线的全自动化,在加衬工位的区域中,采用一个加衬绝缘层转移装置是有利的,而为了散发完成的管绝缘层表面热,在下游侧设一冷却器,否则,当把绝缘层包装时会引起悬垂封口片粘连。
本发明的其他细节,特点和优点,从下文对一个实施方案举例的叙述,便可了解无遗,该举例如附图所示,附图内容如下:
图1为本发明的设备的简略侧视图。其中未表示出金属箔供给装置和带冷却器的转移器;
图2为加被工位的简略侧视图,带有金属箔供给装置和带冷却器的转移器;
图3表示加衬过程的原理图(3a至3d)
图1之左侧为装载工位10之简示图,其中有一个接受轴11,一个向接受轴11移动的输送臂12,并有一个切割装置14由电动机13驱动。接受轴11由一个砍刀形板15保持其固定位置。接受轴11的左端面16有圆锥形结构,较利于受待加衬的无缝的管绝缘层1,绝缘层在这里用玻璃棉制成。接受轴11的右端面有一个圆锥形凹陷17。为了在管绝缘层1上制作连续的纵向裂缝2,布置一个切割装置14(本例中为圆形刀片),向接受轴11中插进,接受轴11在18处有一条在中线上的槽缝。运输臂12固定在一个液压或气压活塞-缸组合件19上,活塞-缸在两个方向上移动,可以移动到位置12‘上去,如图中虚线所示。
在图1的中部有一个卷绕装置20,有一个与接受轴11同心的卷轴21,上面有径向伸出的引导件和驱动条22,和一个齿轮变速机构24连接,齿轮变速机构由电机23驱动,电机23又可以由双向移动的液压或气压活塞缸组合件25推动(图中表示为23′)。对引导条22厚度的选择,使之略小于图3所示纵向槽2的内部宽度,放在有裂缝的绝缘层3内。卷轴21的自由端26处,也是锥形,为的是在17处和接受由11作圆心上的旋转推入连接。
在卷绕装置20的下面有加衬工位30,其中有加热辊31和对加热辊加热的燃气道32。加热辊31由电机34带动齿轮变速机构35,再通过伸缩式万向连接件33驱动。并且,加热辊31和燃气道32的高度可以调节,在本实例中,实际上用两个有螺纹的心轴36,37来调节。心轴用轴38连接到齿轮助动的电动组合件39上。
图2所示为本发明设备的简略侧视图,在50处表示金属箔51的供料装置,在本例中金属箔为铝箔,其中用斜置的玻璃线嵌层增强,嵌层侧涂敷聚乙烯,作为活性的粘合剂。供料配置50主要有本身为已知的所谓片材自动供给器,用一个输送带53和真空吸持器52,供给已经切断的金属箔51。
并且,图2概示真空操作的转移器60,运走已恛衬完毕的管绝缘层4。最后,图2还简示一个冷却器70,把刚加衬的管绝缘层4用空气冷却,以便在加衬过程后,不经中间储藏,而直接用诸如纸箱之类进行包装。
以本发明的设备为基础的管绝缘层1的加衬方法,例如,驻留时间仅需7秒钟,进行此方法的步骤如下:把未切缝的管绝缘层1,通过图中未示的侧向滑道,同心供给装载工位10的接受轴11。然后输送臂12把管绝缘层1,连续推送到接受轴11上,如图1中箭头80所示,同时用旋转圆形刀片14,在管绝缘层1切割或铣削(图1点划线所示)出纵向切缝2(图3)。接受轴11的圆锥形端部16,有把绝缘层1在接受轴11上定中的作用,接受轴11的截面,略小于管绝缘层1内孔的内截面。于是,在输送臂12的连续向前的动作下,把切缝管绝缘层3,推送到与接受轴11同心放置的卷轴21上去,直到输送臂12达到虚线所示的位置12’为止。在这推上的过程中,管绝缘层3一方面由插入纵向切缝2里的砍刀形板15固定位置,然后鼍一方面由同样插入纵向切缝2中的引导条22定位,使之在实际加衬过程中所要求的位置不致旋转。在把管绝缘层1(3)向接受轴11和卷轴21上推送到操作中,由于供料装置50,一条金属箔51被输送带53送到一个预定的位置上(图3a),金属箔51的自由端部54,被一个作轴线平行于加热辊31的旋转的导轨56略微向上弯折,使金属箔51进入准备位置(图3b),  其弯折部分54的外缘接触加热辊31,加热辊31在开始时和管绝缘层3的外表面有一个小间距57,因而弯折部分54的外缘,和管绝层3纵向切缝邻近表面的想象延长平面连接。作为举例,间距57可以是10毫米。由于金属箔51端部54,和用燃气坡面32加热到约280℃的加热辊31接触,箔51的粘合剂已开始活化。然后利用电机驱动的螺纹心轴36,37,把加热辊31升高,直到带金属箔51的加热辊与管绝缘层3的外表面接触。在金属箔51外缘和管绝缘层3接触时,加热辊31在这粘合位置(图3c)上,在实际加衬过程开始前,保持约0.2至0.3秒种。在这短驻留时间内,加热辊31由电机34,通过齿轮变速机构35及成向连接器33所驱动,管绝缘层3也由通过电机23及齿轮变速机构24所带动的卷轴21所驱动,两者的驱动有相同的圆周速度而方向相反,直至加衬管绝缘层4旋转约340到350°(图3d)。这时为了完成封口粘合,加热辊31又在位置上短时停留(0.2至0.3秒钟),然后下降,回到原始位置上。在加热辊31下降的同时,活塞-缸组合件25把卷轴21,按图1中箭头81的方向,从加衬管绝缘层4中外伸(图示23‘的位置)。同时有本身为已知的真空吸持器的转移器60,向管绝缘层旋转,把绝缘层提起,转移到冷却器70的输送带71上,使管绝缘层接触冷却空气,然后落入槽道72,以备用纸箱之类进行包装。
在实际加衬过程中,输送臂按箭头82的方向,从位置12’回到原始位置上,为的是把一根新的管绝缘层1推到接受轴11上。此外,一旦转移器60转开,卷轴21便立刻从位置23’回到其原始位置,如箭头83所示,并同时旋转,使它的引导条22又垂直向下。然后,上文叙述的管绝缘层1的加衬方法,又完全自动进行。
图3中的金属箔51还可以有一个端部58,在箔全部的宽度上有一个粘合剂条,上面盖一个撕揭条,因此当把管绝缘层4(举例而言),放在待加绝缘层的管件上以后,可以把撕揭条揭去,把留下的粘合剂条粘在绝缘层4上,把纵向裂缝2封口。
