Description

用于接合轮胎组成构件的设备及用于制造轮胎组成构件的方法
技术领域
本发明涉及用于接合轮胎组成构件的设备，其被构造成使轮胎组成构件的端部彼此接触并且使端部接合到一起，本发明还涉及用于制造端部彼此接合的轮胎组成构件的方法。
背景技术
片状轮胎组成构件用于形成未硫化轮胎。例如，胎体帘布层围绕成型鼓卷绕并且形成为筒状。此外，在胎体帘布层围绕成型鼓卷绕后，胎体帘布层的前端部和后端部彼此接触并且被接合到一起。作为用于如上所述将轮胎组成构件的端部接合到一起的设备，已知通过成对的接合辊将端部彼此接合的设备。在现有技术的接合设备中，使成对的接合辊沿着轮胎组成构件的端部滚动。轮胎组成构件的端部通过成对的接合辊彼此接触并且被接合到一起（见专利文献1）。
而在用于机动车的子午线轮胎中，使用由有机纤维制成的胎体帘布层。通过利用橡胶覆盖由有机纤维（例如尼龙、人造纤维以及聚酯）制成的织物来形成胎体帘布层。由有机纤维帘线制成的胎体帘布层相对薄并且刚度相对低。因而，通过上述现有技术的接合设备不能够容易地接合胎体帘布层并且胎体帘布层可能被卷入到滚动的接合辊中。
图7是示出用于接合胎体帘布层的现有技术的接合设备的图。在图7中，以截面的形式示出胎体帘布层110的表面部。
在现有技术的接合设备100中，成对的接合辊101（在图7中示出一者的侧面）如图所示地滚动。胎体帘布层110的端部通过接合辊101接合到一起。此刻，在胎体帘布层110的表面，突出部111被强力地压到滚动的接合辊101上。结果，胎体帘布层110可能被卷入到成对的接合辊101中。还担心的是，胎体帘布层110被咬入到成对的接合辊101之间。
随着该运动，胎体帘布层110的橡胶破损并且织物可能松弛。结果，胎体帘布层110的有机纤维帘线可能绕接合辊101卷绕。在该情况下，需要手动地从接合辊101移除有机纤维帘线。根据用于移除有机纤维的劳动力或时间，接合工作的效率降低。此外，在现有技术的接合设备100中，还担心的是，当接合除胎体帘布层110以外的轮胎组成构件时，轮胎组成构件的端部可能被卷入到接合辊101中。因此，从提高工作效率和防止被卷入的观点出发，需要进行改进。

具体实施方式
将参照附图，在下文说明本发明的用于接合轮胎组成构件的设备（以下称为接合设备）和用于制造轮胎组成构件的方法的实施方式。
轮胎组成构件是用于形成轮胎的各部分的构件。本实施方式的接合设备使由橡胶制成的轮胎组成构件的端部彼此接触并且使端部接合到一起。结果，制成端部被接合的轮胎组成构件（接合的轮胎组成构件）。
待接合的轮胎组成构件可以是仅由未硫化橡胶制成的构件，也可以是由未硫化橡胶和帘线（例如胎体帘布层、带束层以及加强构件）制成的构件。轮胎组成构件由橡胶形成为片状。此外，通过切割等使轮胎组成构件形成为预定形状。接合设备使一个或多个轮胎组成构件的端部彼此接触并且通过压接过整个端部的方式使端部接合。下文中，在机动车用的子午线轮胎（PSR）中使用的胎体帘布层将作为轮胎组成构件的示例被加以说明。在该轮胎组成构件（胎体帘布层）中，设置有机纤维帘线。在未硫化轮胎的成型过程中，轮胎组成构件围绕成型鼓的外周卷绕。轮胎组成构件的两端部（前后端部）彼此接触且被接合到一起，并且轮胎组成构件形成为筒状。
图1是示出接合设备的轮廓构造的主视图。在图1中，示出了接合设备的主要部分。
如图所示，接合设备1包括成型鼓2和用于接合轮胎组成构件90的一对接合单元30。该一对接合单元30沿成型鼓2的轴向并置。接合设备1包括沿着成型鼓2的外周面配置的移动部件（移动机构）10。该移动部件10使该一对接合单元30在成型鼓2的轴向和径向（图1的左右方向和竖直方向）上移动。移动部件10配置在成型鼓2的上方。
成型鼓2具有筒状形状并且围绕轴线转动。成型鼓2的外周通过设置于外周的囊状物等扩大和缩小。成型鼓2是在未硫化轮胎成型期间用于支撑待接合的轮胎组成构件90的支撑体。当轮胎组成构件90位于成型鼓2的外周的预定位置时，对轮胎组成构件90进行卷绕。成型鼓2同轴地保持筒状的轮胎组成构件90。此外，成型鼓2以轴线变成水平的方式由驱动装置（未示出）支撑。驱动装置包括驱动源（例如马达）和用于将驱动源的转动动力传递到成型鼓2的传递机构。成型鼓2由驱动装置驱动而转动并且使轮胎组成构件90以预定转动速度转动。成型鼓2使轮胎组成构件90在任意的转动角度停止。
从供给装置（未示出）供给轮胎组成构件90。轮胎组成构件90围绕成型鼓2的外周卷绕或围绕配置有其他构件的成型鼓2卷绕。这里，在卷绕轮胎组成构件90之前，在成型鼓2的外周配置内衬层5。以预定间隔并且彼此相邻地配置轮胎组成构件90的前端部和后端部。轮胎组成构件90的前端部和后端部是如下所述的部分：当卷绕轮胎组成构件90时变成前端和后端，并且前端部和后端部以在它们之间开口有微小间隙的方式以平行的状态彼此相对。通过利用未硫化橡胶覆盖有机纤维帘线（未示出）来形成轮胎组成构件90。在轮胎组成构件90的表面的橡胶中，多个有机纤维帘线沿成型鼓2的轴向配置。接合设备1通过成型鼓2支撑轮胎组成构件90的彼此相对的待接合的两端部。接合设备1通过在成型鼓2上沿着轮胎组成构件90的端部移动接合单元30来使端部彼此接合。接合设备1被构造成关于成型鼓2的轴向上的中央部CL左右对称。接下来，将主要地说明接合设备1的中央部CL的一侧（图1中的左侧）。
移动部件10具有导轨11、螺杆轴12、马达13以及安装导轨11、螺杆轴12、马达13的框架（未示出）。导轨11配置为与成型鼓2的轴线平行。螺杆轴12配置在导轨11的上方并且与导轨11平行。马达13的转动轴13A配置为与螺杆轴12平行。螺杆轴12由框架可转动地支撑。驱动滑轮14被固定到螺杆轴12。驱动滑轮15被固定到马达13的转动轴13A。环带16围绕驱动滑轮14和驱动滑轮15张紧。移动部件10通过驱动滑轮15、带16和驱动滑轮14将马达13的转动动力传递到螺杆轴12。结果，螺杆轴12围绕轴线在两个方向上均以预定速度转动。
移动部件10具有可动构件17、活塞缸体机构18以及振动机构19。可动构件17被安装到螺杆轴12。活塞缸体机构18被固定到可动构件17的侧面。振动机构19安装到活塞杆18P的前端（下端）。接合单元30被安装到振动机构19。可动构件17具有螺纹孔和引导孔，螺杆轴12贯通通过螺纹孔并且导轨11贯通通过引导孔。通过上述螺杆轴12的转动由导轨11引导可动构件17并且可动构件17以预定速度在成型鼓2的轴向上移动。活塞缸体机构18的活塞杆18P配置为沿成型鼓2的径向并且朝向成型鼓2的轴线。活塞缸体机构18通过移动活塞杆18P进出缸体18S而移动振动机构19。结果，接合单元30靠近轮胎组成构件90或远离轮胎组成构件90。此外，移动部件10以预定压力将接合单元30压向轮胎组成构件90的待接合的端部。移动部件10通过马达13来转动螺杆轴12并且沿着轮胎组成构件90的端部移动接合单元30。
接合单元30包括如后文将说明的加压辊32、加强辊50、防止卷入构件70以及成对的接合辊40。移动部件10使辊32、40和50以及防止卷入构件70与接合单元30一起压向轮胎组成构件90的端部并且使辊32、40和50以及防止卷入构件70沿着端部移动。辊32、40和50沿着轮胎组成构件90的端部滚动。接合单元30具有固定构件60和框体31。固定构件60被固定到振动机构19。框体31被安装到固定构件60的下面并且沿着轮胎组成构件90的外周配置。固定构件60和框体31通过移动部件10一体地移动。接合单元30通过设置于框体31的辊32、40和50以及防止卷入构件70来接合轮胎组成构件90的端部。借助于振动机构19的微小角度的振动来改变接合单元30的配置角度。结果，接合单元30沿法线方向对轮胎组成构件90加压。
图2是在接合期间的接合单元30的平面图。在图2中示出当从图1中的箭头X方向观察时的、接合单元30的主要部分。在图2中示出的接合单元30中，示出透过固定构件60（在图2中以虚线表示）观察到的、框体31侧的构造。图2还示出接合单元30附近的轮胎组成构件90。在图2中，轮胎组成构件90的接合前的两个端部91和92被示出在左侧。微小的间隙R设置于两个端部91和92之间。在图2中，轮胎组成构件90的接合部93被示出在右侧。接合部93是通过接合单元30的运动而被接合的部分。
如图所示，接合单元30具有防止卷入构件70、加压辊32、加强辊50以及成对的接合辊40（40A和40B）。在接合单元30中设置至少一对接合辊40。防止卷入构件70防止轮胎组成构件90被卷入到成对的接合辊40中。
加压辊32、成对的接合辊40以及加强辊50沿接合单元30的移动方向（接合方向）S配置。移动方向S是在轮胎组成构件90接合期间接合单元30移动的方向。加压辊32、成对的接合辊40以及加强辊50在移动方向S上从前往后依次配置。加压辊32和加强辊50相对于接合辊40配置在移动方向S上的前方和后方。接合辊40夹在加压辊32和加强辊50之间。辊32、40和50配置于框体31中并且分别由轴构件33、34和35支撑为可围绕轴线转动。轴构件33、34和35被安装到框体31并且通过轴承（未示出）支撑辊32、40和50。接合单元30在移动方向S上具有多对（这里为两对）接合辊40。此外，在每对接合辊40的移动方向S的前方，分别设置防止卷入构件70。防止卷入构件70配置在接合辊40和加压辊32之间并且还配置在前后接合辊40之间。
加压辊32的外周面形成为带凹曲面的鼓形状。加压辊32的轴向配置成与成型鼓2的轴向垂直的方向。在此状态中，加压辊32由轴构件33支撑。加压辊32和接合辊40一起被压到轮胎组成构件90的两个端部91和92上。在加压辊32的接触范围中，端部91和92被夹在加压辊32和成型鼓2之间。加压辊32对端部91和92加压。此刻，加压辊32以相对低的压力来压轮胎组成构件90。结果，防止端部91和92向上浮起。加压辊32和接合辊40在轮胎组成构件90的端部91和92上滚动。接合单元30通过加压辊32来压两个端部91和92并且接着通过成对的接合辊40来接合端部91和92。
成对的接合辊40中的每个接合辊均形成为筒状形状。成对的接合辊40的一端部由相应的轴构件34（34A和34B）支撑。成对的接合辊40被配置成关于轮胎组成构件90的接合部93对称。以分别从接合部93侧（内侧）朝向外侧地向移动方向S的后侧（图2中右侧）倾斜的方式配置成对的接合辊40的轴线。在该接合辊40中，轴线的角度Y形成相对小的预定角度（例如5°到30°的角度）。角度Y是轴线相对于与接合部93垂直的方向的角度。在成对的接合辊40中，两个轴线的交叉点位于接合部93上。成对的接合辊40具有多个突起41（41A和41B），该多个突起分别在彼此相对的边缘部沿轴向突出。沿着成对的接合辊40的边缘部以相等的间隔形成突起41。在成对的接合辊40中，突起41和在突起41之间的凹部以相同的节距在周向上交替地设置。突起41和凹部在成对的接合辊40的周向上交替地配置。在成对的接合辊40中的一个接合辊40上的突起41进入另一个接合辊40的突起41之间（凹部）。成对的接合辊40通过突起41彼此间的咬合而以相等的速度同步转动。
图3是一个接合辊40的当从径向外侧观察时的主视图。在图3中，以截面的形式示出接合辊40的一部分（图中的上部）。
如图所示，突条T形成于接合辊40。突条T形成为在接合辊40的周向上环状地（或螺旋状地）地延伸。突条T形成为以多个的形式并置在接合辊40的外周。接合辊40的截面形状形成为并置多个突出部的锯齿形状。在该突条T中，突起41侧的侧面与接合辊40的轴向垂直，而另一侧的侧面以预定角度倾斜。突条T形成有三角形截面并且配置在接合辊40的包括突起41的整个外周。突条T被压到轮胎组成构件90的端部91和92上。接合辊40通过突条T对端部91和92的预定范围加压。
接合设备1通过移动部件10（见图1）来移动接合单元30。此外，该设备通过移动部件10将加压辊32压向轮胎组成构件90的两个端部91和92（见图2）。接合设备1将接合辊40A和40B分别压向端部91和92。关于间隙R对称地压接合辊40A和40B。在此状态中，接合单元30沿着端部91和92在移动方向S上移动。结果，使得以相反的方向倾斜的接合辊40A和40B在各端部91和92上同步滚动。
随着接合辊40A和40B的滚动，力从接合辊40A和40B的突条T被施加到轮胎组成构件90。例如在与突条T垂直的方向上的力被施加到轮胎组成构件90。如上所述，在轮胎组成构件90的端部91和92上作用有在使得端部91、92彼此接近的方向上的力。利用该力，两端部91和92被拉向彼此并且在消除间隙R的同时使得彼此接触。通过从接合辊40A和40B施加的压力来压接端部91和92的端面。同时，力从接合辊40A和40B的彼此咬合的突起41A和41B交替地作用于端部91和92。端部91和92的表面交替地变形到另一侧并且接合。结果，端部91和92被接合到一起。
图4是示出接合后的轮胎组成构件90的接合部93附近的示意图。图4的A是接合部93的立体图，并且图4的B是图4的A的V-V箭头线上的截面图。
如图所示，轮胎组成构件90具有多个有机纤维帘线C。通过端部91和92的接合，在表面侧（图4的A和B中的上侧）的橡胶93W由突起41A和41B部分地拉伸。橡胶93W被交替地拉伸到端部91和92的表面。接合部93在内侧（图4的AB的下侧）被直线地压接。另一方面，接合部93在表面侧以波浪状态接合。端部91和92在表面侧交替地与另一侧的表面重叠。
如上所述，接合设备1将成对的接合辊40（见图2）压向轮胎组成构件90的待接合的、夹有间隙R的各端部91和92。此外，使成对的接合辊40分别在轮胎组成构件90的相对的各端部91和92上滚动。随着滚动，成对的接合辊40在将两个端部91和92拉向彼此的情况下使端部91和92（两端面）彼此接触并且使它们接合到一起。轮胎组成构件90被连续地接合并且形成为筒状。此刻，通过移动部件10，接合设备1使前后这两对接合辊40一起滚动。由于两对接合辊40连续地进行相似的接合操作，因此端部91和92被强力地接合。
在通过接合辊40接合之后，接合设备1通过加强辊50（见图2）压轮胎组成构件90的接合部93。加强辊50形成为柱状并且由轴构件35支撑。加强辊50与加压辊32和成对的接合辊40一起被压到轮胎组成构件90的两个端部91和92上。随着接合单元30的移动，加强辊50在移动方向S上向成对的接合辊40的后方连续地滚动。加强辊50通过压被接合到一起的两个端部91和92来强化端部91和92之间的接合。
在加强辊50的外周面51，通过滚花交叉地设置多个倾斜的凹槽。加强辊50的外周面51由多个凹槽形成为与橡胶具有较大摩擦力的粗糙表面（凹凸面）。加强辊50在滚动期间利用外周面51对被接合的轮胎组成构件90的两端部91和92（接合部93）加压。同时，加强辊50通过外周面51摩擦彼此接触的两个端部91和92。利用加强辊50的压力，轮胎组成构件90的两个端部91和92以相互朝向另一侧膨出的方式变形。结果，两端部91和92被更强力地压接。同时，加强辊50通过利用外周面51碾过两个端部91和92之间的接合界面来顺次强化端部91和92之间的接合。结果，端部91和92牢固地接合到一起。
接合设备1包括用于从内侧（或外侧）加热加强辊50的加热部件（未示出）。接合设备1通过加热部件将加强辊50的外周面51加热到预定温度（这里为70°C到100°C）。加强辊50加热轮胎组成构件90的两个端部91和92。结果，通过加强辊50来强化接合的效果得到提高。端部91和92以高接合强度更牢固地接合到一起。
随后，将说明设置于接合单元30的侧部的构造。此外，还将说明设置于固定构件60的构造。然而，接合单元30在辊32、40和50的两侧的构造相似。因而，接下来，将作为示例说明接合单元30的仅一侧的侧部（图2中的下部）。
图5是示出接合单元30的主要部分的侧视图。在图5中，示出当从图2中的箭头Z方向观察时的接合单元30。在图5中示出的接合单元30处于辊32、40和50与轮胎组成构件90间隔开的状态。
辊32、40和50的轴构件33、34和35如图所示具有截面为矩形的方杆形状并且贯通框体31的侧面。轴构件33、34和35从框体31的内侧朝向外侧（图5中的垂直于纸面向外侧）突出。在位于沿移动方向S的后侧的成对的接合辊40（以下称为固定接合辊40F）中，轴构件34被固定在框体31的通孔中。因而，固定接合辊40F与框体31一体地移动。
在位于前侧的接合辊40（以下称为移位接合辊40D）、加压辊32和加强辊50中，轴构件33、34和35被插入到引导孔36、37和38中。引导孔36、37和38具有矩形形状并且贯通框体31的侧面。轴构件33、34和35由引导孔36、37和38引导并且在引导孔36、37和38中沿长度方向（图5中的上下方向）移位。此外，轴构件33、34和35在引导孔36、37和38中被锁定。在不改变姿势并且不改变从框体31突出的长度的情况下，轴构件33、34和35在引导孔36、37和38中移位。通过加压部件61、62和63在移位方向上的一个方向（图5中的向下方向）上压轴构件33、34和35。加压部件61、62和63被固定到固定构件60的侧部并且压轴构件33、34和35的从框体31突出的部分。
各加压部件61、62和63由例如柱塞或弹性构件（弹簧等）形成。柱塞通过内侧的弹簧朝向外侧对销状加压构件加压。这里，各加压部件61、62和63由柱塞制成并且以朝下的方式配置于固定构件60。加压部件61、62和63通过加压构件61A、62A和63A一直向轴构件33、34和35施加向下的压力。结果，轴构件33、34和35位于引导孔36、37和38的最下侧。加压部件61、62和63以比移动部件10将辊32、40和50压到轮胎组成构件90上的力小的力压轴构件33、34和35。如果辊32、40D和50被压到轮胎组成构件90上，则加压部件61、62和63使轴构件33、34和35在引导孔36、37和38中向上移位。加压部件61、62和63使轴构件33、34和35在引导孔36、37和38中移位并且使辊32、40D和50移位。辊32、40D和50基于由移动部件10压到轮胎组成构件90上的固定接合辊40F而移位。加压部件61、62和63基于固定接合辊40F根据轮胎组成构件90的表面上的凹凸而使辊32、40D和50移位。
如上所述，加压部件61、62和63在将滚动辊32、40D和50压到轮胎组成构件90的端部91和92上的期间，使滚动辊32、40D和50移位。加压部件61、62和63以跟随端部91和92的凹凸的方式使辊32、40D和50移位。因此，加压部件61、62和63构成用于使辊32、40D和50移位的移位部件64、65和66。利用移位部件64、65和66，除固定接合辊40F以外的辊32、40D和50在与框体31一体地移动时移位。辊32、40D和50彼此独立地移位并且独立于固定接合辊40F地移位。接合设备1通过移位部件64、65和66根据轮胎组成构件90的各按压位置处的凹凸而使加压辊32、移位接合辊40D以及加强辊50移位。结果，使得辊32、40D和50跟随端部91和92的凹凸。此外，接合设备1使得辊32、40D和50以与端部91和92接触的状态（受压状态）滚动。
成对的固定接合辊40F被配置成与轮胎组成构件90的端部91和92隔开并且从其他辊32、40D和50移位的状态。该成对的固定接合辊40F被配置成通过移动部件10在加压方向上移位到相反侧（图5中的上侧）。因而，在通过移动部件10的加压使其他与端部91和92接触的辊32、40D和50移位之后，固定接合辊40F与端部91和92接触。此外，利用移动部件10的压力，以相对强的力将固定接合辊40F压到端部91和92上。
根据加压部件61、62和63的压力，其他辊32、40D和50被以相对弱的力压到轮胎组成构件90的端部91和92上。此刻，由于加压辊32仅需要压端部91和92并且防止端部91和92向上浮起，因此以相对弱的力压加压辊32。以相对弱的力压移位接合辊40D，使得端部91和92能够靠近而不会与下侧的构件紧密接触。以相对强的力压加强辊50，以便可靠地强化端部91和92之间的接合。根据相应的压力，设定各加压部件61、62和63的压力。
本实施方式的接合设备1在接合单元30中包括上述防止卷入构件70。防止卷入构件70配置在各对接合辊40的移动方向S上的前方。防止卷入构件70与接合单元30一体地移动，同时对轮胎组成构件90的端部91和92加压。防止卷入构件70防止端部91和92被卷入到滚动着的成对的接合辊40之间或防止端部91和92被卷入到接合辊40中。此外，防止卷入构件70还防止轮胎组成构件90被成对的接合辊40之间的突起41咬入。
防止卷入构件70由被形成为预定形状的板状构件形成并且从框体31以朝向下方的状态配置。防止卷入构件70具有在框体31侧的基部71和用于压轮胎组成构件90的两端部91和92的加压部72。加压部72具有三角形截面并且从基部71的下端朝向移动方向S上的后方配置。此外，加压部72沿着接合辊40的外周配置。加压部72的下端面（加压面）被压到轮胎组成构件90上。加压部72的下端面形成为平滑的平面状并且配置为与接合辊40的下端相适应。
防止卷入构件70在沿长度方向（见图2）的中央部处沿相反的方向弯曲并且防止卷入构件70被配置为与成对的接合辊40平行。防止卷入构件70整体上配置在接合辊40的移动方向S上的前方。加压部72（见图5）形成于防止卷入构件70的下端的全体。加压部72配置在成对的接合辊40的在移动方向S上的前方并且还配置为靠近成对的接合辊40。在接合辊40的外周和加压部72之间，开设具有预定间隔的间隙。在该状态下，沿着接合辊40的外周配置加压部72。加压部72与成对的接合辊40一起被压到轮胎组成构件90上。防止卷入构件70通过加压部72沿着成对的接合辊40的外周压轮胎组成构件90的两个端部91和92。
这里，一个防止卷入构件70（移位接合辊40D前方的防止卷入构件70）具有连续到基部71的连接件73。连接件73在框体31侧被安装到移位接合辊40D的轴构件34。因而，该防止卷入构件70与移位接合辊40D一体地移位。另一个防止卷入构件70（固定接合辊40F前方的防止卷入构件70）具有被固定到框体31的基部71。因而，该另一个防止卷入构件70与固定接合辊40F相似地在接合单元30中具有固定位置。如上所述，关于防止卷入构件70，彼此组合的成对的接合辊40的位置关系被保持。防止卷入构件70在接合辊40的移动方向S上的前方与接合辊40一起与轮胎组成构件90接触。
以与成对的接合辊40上的、和轮胎组成构件90相对的部分（图5中的下部）重叠的方式配置防止卷入构件70的加压部72。也就是，加压部72配置在成对的接合辊40和轮胎组成构件90之间并且进入成对的接合辊40和轮胎组成构件90之间的间隙。当从轮胎组成构件90的法线方向（图5中的箭头N方向）观察时，加压部72隐藏在成对的接合辊40中。此外，防止卷入构件70的加压部72配置在成对的接合辊40的在移动方向S上的前方附近。假定在移动方向S上从接合辊40的外周到加压部72的距离为K。在前方附近的附近是指K在5mm内并且是加压部72不与接合辊40接触的位置。这里，配置加压部72使得加压部72和接合辊40之间的间隙（距离K）约为1mm。
图6是示出轮胎组成构件90的端部91和92由成对的接合辊40接合到一起的状态的图。在图6中，以侧视图的形式示意性地示出一个接合辊40和防止卷入构件70的加压部72。以截面图的形式示出轮胎组成构件90的表面部。
如上所述，防止卷入构件70具有加压部72，该加压部72用于在成对的接合辊40的沿移动方向S的前方附近压轮胎组成构件90的两个端部91和92。在两个端部91和92与接合辊40接触之前，防止卷入构件70通过加压部72压轮胎组成构件90的待由接合辊40接合的两个端部91和92。防止卷入构件70对端部91和92的浮起状态或表面的突出部95加压而使端部91和92平坦。防止卷入构件70使两端部91和92以相对平坦的状态与成对的接合辊40接触。
成对的接合辊40继防止卷入构件70之后在端部91和92上滚动，并且随后使端部91和92接合到一起。此刻，成对接合辊40滚动而不咬入轮胎组成构件90。突出部95也未被咬入到成对的接合辊40的突起41之间。如上所述，在防止卷入构件70与成对的接合辊40一起移动的情况下，防止卷入构件70在接合辊40的沿移动方向S（行进方向）的前方对轮胎组成构件90的两个端部91和92加压。结果，防止卷入构件70在轮胎组成构件90的接合期间防止两个端部91和92卷入到成对的接合辊40中。
随后，将说明通过接合设备1使由橡胶形成的轮胎组成构件90的两个端部91和92接合到一起的步骤。此外，将说明通过将端部91和92接合到一起而制造接合的轮胎组成构件90的制造方法。在设置于接合设备1的控制器（未示出）的控制下，执行以下步骤和操作。控制器由例如计算机组成。控制器通过连接部件而被连接到设备中的各部分。控制器控制设备中的各部分，从而进行用于接合的操作。
如果轮胎组成构件90（见图1）待接合，则首先将筒状构件（内衬层5等）配置在成型鼓2的外周。在这之后，使轮胎组成构件90围绕转动成型鼓2的外周卷绕一周。通过移动部件10使轮胎组成构件90的两个端部91和92配置在接合单元30的加压位置。成型鼓2以使端部91和92彼此相对的方式支撑端部91和92。随后，接合设备1通过移动部件10在成型鼓2的中央部CL使接合辊30中的一者（图1中左侧的一者）降低。此外，接合设备1以预定的压力将辊32、40和50以及防止卷入构件70压到端部91和92上（见图2）。
随后，接合单元30向成型鼓2的轴向外侧移动。辊32、40和50以及防止卷入构件70沿着轮胎组成构件90的端部91和92一体地移动。结果，使得加压辊32和成对的接合辊40在轮胎组成构件90的待接合的相对的各端部91和92上沿移动方向S滚动。利用成对的接合辊40，两端部91和92彼此靠近并且端部91和92彼此接触且接合到一起。同时，利用防止卷入构件70，在成对的接合辊40的移动方向S上的前方的、轮胎组成构件90的两个端部91和92受压并且防止两个端部91和92被卷入到成对的接合辊40中。此刻，防止卷入构件70通过加压部72对位于成对的接合辊40的移动方向S上的前方附近的轮胎组成构件90加压。此外，加压部72沿着成对的接合辊40的外周对轮胎组成构件90的两个端部91和92加压。
接合设备1还使得被加热的加强辊50滚动。通过加强辊50来加热和加压彼此接触的两个端部91和92，并且端部91和92之间的接合如上所述地被加强。随后，当接合单元30中的一者已移动预定距离时，接合设备1在成型鼓2的中央部CL使另一（图1中右侧的一者）接合单元30降低。接合设备1将辊32、40和50压到接合的端部91和92上。随后，一对接合单元30在相反方向上移动。一对接合单元30以相同的速度朝成型鼓2的轴向外侧移动。结果，使得辊32、40和50沿着端部91和92滚动，并且端部91和92彼此全面地接合。此后，将另一个轮胎组成构件配置在接合的轮胎组成构件90上，从而形成具有预定形状和结构的未硫化轮胎。使未硫化轮胎硫化并且成型，从而制造各种类型的轮胎。
如上所述，在该接合设备1中，通过防止卷入构件70压轮胎组成构件90的两个端部91和92。利用防止卷入构件70，防止端部91和92被成对的接合辊40卷入。特别地，甚至相对薄并且刚度相对低的轮胎组成构件90（例如具有有机纤维帘线C的胎体帘布层）也能够被可靠地防止围绕接合辊40卷绕并且被可靠地防止卷入到成对的接合辊40之间。因而，轮胎组成构件90的橡胶不破损并且织物不会松开。有机纤维帘线C不会围绕接合辊40卷绕。结果，对于被接合后的轮胎组成构件90，能够确保高质量。由于不再需要从接合辊40移除有机纤维帘线C的工作，所以能够连续地进行轮胎组成构件90的接合。结果，减少了接合期间的劳动力和时间，并且能够提高接合工作的效率。
因此，根据本实施方式，当轮胎组成构件90的端部91和92待彼此接触并且待接合到一起时，能够防止待接合的端部91和92被成对的接合辊40卷入。此外，能够提高接合工作的效率。通过防止卷入构件70压两个端部91和92并且通过成对的接合辊40将端部91和92接合到一起。因而，端部91和92能够均匀地、准确地接合到一起。即使在薄的轮胎组成构件90中，也能够以足够的强度将端部91和92接合到一起。通过利用防止卷入构件70的加压部72在接合辊40的移动方向S上的前方附近压两个端部91和92，能够在接合操作期间相对于接合辊40在适当的和靠近的位置压两个端部91和92。结果，能够更加可靠地防止端部91和92被成对的接合辊40卷入。还能够进一步提高端部91和92之间的接合准确性。
这里，如果轮胎组成构件90的刚度低，则难以在成型鼓2的外周直线地配置轮胎组成构件90的端部91和92。即使端部91和92不能够如上地准确地配置，也能通过防止卷入构件70预先压两个端部91和92从而使端部91和92在位置和形状均等的状态下与成对的接合辊40接触。因而，待接合的端部91和92被维持成相同的状态，并且能够通过成对的接合辊40将端部91和92可靠地接合到一起。此外，由于能够充分地确保成对的接合辊40与轮胎组成构件90接触的面积，因此端部91和92的波动的影响变得难以发生作用。因此，能够适当地接合轮胎组成构件90。
在该接合设备1中，通过接合单元30即使在成型鼓2上也能够可靠地接合轮胎组成构件90的端部91和92。因而，接合设备1适于对围绕成型鼓2卷绕的轮胎组成构件90进行接合。当接合设备1被用在成型鼓2上时，能够获得很好的效果。即使轮胎组成构件90是除以上类型以外类型的胎体帘布层或是除胎体帘布层以外的构件，通过使用接合设备1，端部91和92也能够被可靠地接合到一起而不会被成对的接合辊40卷入。
如果通过防止卷入构件70沿着成对的接合辊40的外周对轮胎组成构件90的两个端部91和92加压，则端部91和92在与接合辊40接触之前能够可靠地受压。此外，由于能够在防止卷入构件70加压的整个范围内获得相同程度的防止卷入效果，所以能够更加可靠地防止端部91和92被卷入到接合辊40中。此刻，防止卷入构件70优选地配置为与接合辊40平行。然而，如果能够在防止卷入构件70和接合辊40之间确保具有预定间隔的间隙，则无需使得防止卷入构件70与接合辊40平行。
在本实施方式中，在前后方配置了两对接合辊40，也可以设置一对或三对或更多对接合辊40。如果将在移动方向S上组装多对接合辊40，则能够可靠地并且牢固地接合轮胎组成构件90的端部91和92。此外，如果将设置多对接合辊40，则优选地在各对接合辊40的移动方向S上的前方均设置防止卷入构件70。通过如上构造，能够在各对接合构件40的前方压端部91和92，并且能够更加可靠地防止端部91和92的卷入。同时，各对接合辊40均能够获得防止卷入构件70的各上述效果。然而，由于位于移动方向S上的最前方的一对接合辊40首先进行端部91和92的接合操作，因此通过防止卷入构件70对两个端部91和92加压的必要性最大。因而，对于多对接合辊40，可以至少在位于移动方向S上的最前方的一对接合辊40处设置防止卷入构件70。
通过利用板状构件来构造防止卷入构件70，便于防止卷入构件70的加工。利用板状防止卷入构件70，能够可靠地压两端部91和92，并且还能够抑制表面橡胶的损伤。另一方面，防止卷入构件70还能够由能够防止端部91和92被卷入到接合辊40中的其他构件形成。防止卷入构件70还能够由除板状构件以外的梳形状构件、小径辊或厚直线构件形成。
已说明了在成型鼓2上接合轮胎组成构件90的示例。另一方面，通过使用接合设备1，轮胎组成构件90能够类似地接合到除成型鼓2以外的支撑体。例如，利用接合设备1，轮胎组成构件90还能够在例如平面状支撑构件或输送器上被接合。
