Description

未硫化带状橡胶构件的带分隔物的卷取衬垫的制造方法及其装置、以及该卷取衬垫的分隔物构件的制造方法及其装置
技术领域
本发明涉及未硫化带状橡胶构件的带分隔物(spacer)的卷取衬垫(liner)的制造方法及其装置、以及该卷取衬垫的分隔物构件的制造方法及其装置，更详细地说，涉及例如能够将到成形时为止需要保持一定的挤压形状的轮胎胎面或胎侧橡胶构件等未硫化带状橡胶构件不变形地卷取成卷状进行保持、保管的、未硫化带状橡胶构件的带分隔物的卷取衬垫的制造方法及其装置、以及该卷取衬垫的分隔物构件的制造方法及其装置。
背景技术
以往，在轮胎成形工序等中，如图12所示，进行下述的方法:通过切断装置2，将通过挤压机1挤压成形并赋形(型付，赋予形状等、成形、轧花)的包括轮胎胎面、胎侧橡胶构件等轮胎结构构件的未硫化带状橡胶构件W定长切断成规定的长度，然后出于直到轮胎成形时为止保持形状等的目的，将该定长切断的未硫化带状橡胶构件Wa多层状地载置在货车(ケリ—トラック)等台车3上进行保管。
但是，被定长切断的未硫化状态的轮胎胎面、胎侧橡胶构件等未硫化带状橡胶构件Wa在放置到之后的轮胎成形时使用为止的期间内，由于冷却等而产生形状尺寸的收缩，轮胎成形时材料的尺寸精度变得不稳定，成为使轮胎成形后的轮胎均匀性恶化的原因。
因此，近年来如图13所示，将由挤压机1挤压成形并赋形的未硫化带状橡胶构件W并不预先定长切断，而夹着卷取衬垫R地以长条状态卷取成卷状(筒状)，在即将成形使用之前开卷(卷出)并定长切断，由此抑制材料的形状尺寸的收缩，保证尺寸精度(例如，参照专利文献1)。
但是，以往的卷取衬垫，包括:具有未硫化带状橡胶构件的至少宽度以上的横向宽度的树脂制的不伸缩性的带状的载置件，和在该载置件表面的宽度方向两侧缘部由橡胶材料形成为具有未硫化带状橡胶构件的至少厚度以上的高度的凹凸状的、实心的分隔物部；将未硫化带状橡胶构件夹在该实心的分隔物部之间地卷取成卷状而保管。然而，存在由于卷取衬垫的自重和未硫化带状橡胶构件的自重而下垂的问题，并且存在未硫化带状橡胶构件的赋形的形态损坏、崩塌的问题。
而且，由于将由橡胶材料构成的实心的分隔物部固定在载置件表面的宽度方向两侧缘部，所以相对于长度方向的伸缩性较小并且重量增大，而且在弯曲成卷状使用的情况下，分隔物部的弯曲阻力较大，存在棒条(栈，棂条，梃)的形状变形或损伤而不能再使用等问题。另外，由于使用实心的分隔物部，所以即使赋形的未硫化带状橡胶构件的形状得到保持，也存在分隔物部之间的空气的流通较差、保管时的加温·冷却效率极差的问题。
因此，本申请的发明者等申请了能够使卷取衬垫的重量轻型化、并且能够不引起分隔物构件的损伤地反复使用、能够保持未硫化带状橡胶构件的形状、提高保管时的加温·冷却效率的未硫化带状橡胶构件的卷取衬垫以及该卷取衬垫的制造方法(例如，参照专利文献2)。
但是，在上述的申请中，并没有提出连续高效地进行未硫化带状橡胶构件卷取衬垫的的分隔物构件的制造以及带分隔物的卷取衬垫的制造的方法和装置。

本发明着眼于该以往的问题点，其目的在于提供一种能够高效且连续地制造带分隔物的卷取衬垫以及该卷取衬垫的分隔物构件的、未硫化带状橡胶构件的带分隔物的卷取衬垫的制造方法及其装置，以及该卷取衬垫的分隔物构件的制造方法及其装置。
为了达成上述目的，本发明的未硫化带状橡胶构件的带分隔物的卷取衬垫的制造方法，其主旨在于:使从材料的开卷辊开卷的板状的带状材料通过赋形装置而连续成形为凹凸状，在该成形为凹凸状的带状的分隔物构件的单面上贴附粘接构件，沿着板状的基础构件的长度方向的侧缘部贴附这样构成的分隔物构件的粘接面。
另外，本发明的其它的未硫化带状橡胶构件的带分隔物的卷取衬垫的制造方法，其主旨在于:使从材料的开卷辊开卷的板状的带状材料通过赋形装置而连续成形为凹凸状，在该成形为凹凸状的带状的分隔物构件的单面上贴附粘接构件，沿着从开卷装置开卷的板状的基础构件的长度方向的侧缘部连续地贴附该分隔物构件的粘接面。
在这里，也可以:在将所述分隔物构件贴附在板状的基础构件上的工序中，通过紧固连接构件将规定长度的分隔物构件的末端部固定。

具体实施方式
下面，基于附图，对本发明的实施方式进行说明。另外，在下面的说明中对于与以往例相同的结构要素标注相同符号而省略说明。
图1是表示实施本发明时的通过卷取衬垫R将未硫化带状橡胶构件W卷取在芯材10上的状态的立体图，本发明的卷取衬垫R，包括:由铝合金(JIS A3000系、A5000系、A6000系的合金等)制的板材形成的带状的基础构件11，和安装在该基础构件11的表面的宽度方向两侧缘部的形成为凹凸状的带状的分隔物构件12a、12b。
具体地说，所述带状的基础构件11是对厚度0.6mm～1.0mm的铝合金(JIS A5052P)制的板材的表面进行铝表面钝化处理加工而成的，该基础构件11具有卷取保管的未硫化带状橡胶构件W的至少宽度h以上的横向宽度H。
另外，所述形成为凹凸状的带状的分隔物构件12a、12b如图2所示，由厚度0.5mm～0.8mm的铝合金(A5052P)制的窄幅板材形成，为了相对于长度方向具有伸缩性，沿着长度方向以规定间距P形成剖面大致梯形形状的凹凸部13，沿着长度方向通过粘接构件14(在该实施方式中使用双面胶带，但不限定于双面胶带，也能够使用通常的粘接剂)平行地安装在所述基础构件11表面的宽度方向两侧缘部。
即，剖面大致梯形形状的凹凸部13具有至少未硫化带状橡胶构件W的厚度t以上的高度T，凹凸部13的宽度、高度T以及间距P根据保管的未硫化带状橡胶构件W的剖面形状等的大小任意地设定。
作为上述那样的卷取衬垫R的制造方法有:分别制造带状的基础构件11和形成为凹凸状的带状的分隔物构件12a、12b、然后通过粘接构件14组装而制造的方法，和连续地制造带状的分隔物构件12a、12b、同时一边通过粘接构件14将该分隔物构件12a、12b贴附在带状的基础构件11上一边连续地制造的方法。
作为单独地制造所述带状的分隔物构件12a或12b的方法，如图3～图5所示，从能够旋转驱动地架设在支撑台15上的材料开卷辊16将板状的带状材料Rw开卷，使该开卷的带状材料Rw通过导向滚筒17a、17b和导向构件18，然后通过图6所示的赋形装置19的一对赋形齿轮19a、19b之间而连续成形为凹凸状，在该成形为凹凸状的带状的分隔物构件12a或12b的单面上通过粘接构件贴附装置20贴附粘接构件14，这样进行制造。
另外，在上述的说明中，说明了从材料开卷辊16使卷取的一张板状的带状材料Rw通过赋形装置19的一对赋形齿轮19a、19b之间而连续成形为凹凸状的方法，但也能够并列设置多台赋形装置19、将多张板状的带状材料Rw同时赋形成凹凸状。
能够旋转驱动地架设在所述支撑台15上的材料开卷辊16，如图4以及图5所示，经由设置在支撑台15上的轴承构件21a、21b旋转自如地支持有辊轴22，在该辊轴22的一端侧，设有带式制动器23和手动式操作柄24，另外在另一端侧设有经由轴承构件21b使辊轴22在轴的长度方向上移动的移动用操作柄25。
另外，在材料开卷辊16的侧面上，朝向径方向地配设有用于防止板状的带状材料Rw在开卷时蛇行的蛇行防止用的导辊26。
接下来，图6所示的赋形装置19由具有规定间距的凹凸刃的能够旋转驱动的一对赋形齿轮19a、19b构成，该赋形齿轮19a构成为由驱动马达27经由链条或带等驱动传递装置28以规定的速度旋转驱动。
所述粘接构件贴附装置20，如图7以及图8所示，包括将粘接构件14转印到分隔物构件12a或12b的单面上的转印辊29，和将粘接构件14贴附到该转印辊29的表面的贴附装置30。该贴附装置30构成为:经由压接辊33将从双面胶带开卷辊31开卷的双面胶带32的粘接剂涂覆面压接，并且将粘接构件14转印到转印辊29的外周面上，双面胶带32的剥落纸34由纸卷取辊35卷取。
涂覆有所述粘接构件14的分隔物构件12a或12b在导向齿轮44a、44b之间通过而向衬垫卷取装置36等的下一工序搬运。另外所述转印辊29的辊轴38如图8所示，经由轴承构件40a、40b能够旋转驱动地架设在支撑台39上，在材料开卷辊30的一端侧，设有带式制动器41和手动式操作柄42，另外在另一端侧设有经由轴承构件40b使辊轴38在轴的长度方向上移动的移动用操作柄43。
这样，在预先以规定的长度制造出规定的大小的分隔物构件12a、12b后制造卷取衬垫R时，经由粘接构件14将分隔物构件12a、12b贴附在基础构件11的表面的宽度方向两侧缘部而制造。另外，规定长度的分隔物构件12a、12b，以经由铆钉等紧固连接构件连接末端部的状态贴附在基础构件11的表面上。
接下来，一边经由粘接构件14将分隔物构件12a、12b贴附在带状的基础构件11上一边连续地制造的方法如图9～图11所示，从能够旋转驱动地架设在支撑台15上的材料开卷辊16将板状的带状材料Rw开卷，使该开卷的带状材料Rw经由导向滚筒17a、17b和导向构件18通过赋形装置19而连续成形为凹凸状，在该成形为凹凸状的带状的分隔物构件12a或12b的单面上经由粘接构件贴附装置20贴附粘接构件14，这样进行制造。
此时，将贴附有粘接构件14的带状的分隔物构件12a或12b的单面(粘接面)，沿着从开卷装置45开卷的板状的基础构件11的长度方向的侧缘部连续地贴附。然后，贴附有分隔物构件12a、12b的基础构件11在导向齿轮44a、44b之间通过而向衬垫卷取装置36搬运，并且一边在该过程中将规定的长度的分隔物构件12a、12b的末端部经由铆钉等紧固连接构件46连接固定在基础构件11上一边通过衬垫卷取装置36卷取。
衬垫卷取装置36，如图10以及图11所示，经由设置于支撑台49上的轴承部件50a、50b能够旋转驱动地架设卷取辊47的辊轴48，在辊轴48的一端侧设置有棘轮51、链轮(sprocket)52a，经由链条52b连接于图未示的驱动马达，在另一端侧设置有经由轴承部件50b使辊轴48在轴的长度方向上移动的移动用操作柄53。
在该实施方式中，连续地制造规定的大小的分隔物构件12a、12b，并且在制造后经由粘接构件14将分隔物构件12a、12b贴附在基础构件11的表面的宽度方向两侧缘部上，由此能够不经由人手地连续地制造卷取衬垫R，另外制造出的规定长度的卷取衬垫R卷状地卷取在衬垫卷取装置36的卷取辊47上来进行保管。
另外，其它的结构以及作用与上述实施方式同样所以标注相同符号而省略说明。如上所述，通过铝合金制的板材形成带状的基础构件11和具备凹凸部13的分隔物构件12a、12b后、将其组合来制作，所以制作容易且廉价，另外能够使卷取衬垫R整体的重量轻型化。另外，对于分隔物构件12a、12b，将板材加工成凹凸状后经由双面胶带等粘接构件14以及铆钉等紧固连接构件46相对于长度方向连接固定，能够安装成可进行伸缩，所以在将卷取衬垫R卷起来时阻力较小，能够容易地弯曲。
