Description

橡胶构件接合装置
技术领域
本发明涉及用于将片状橡胶构件的端部彼此抵接以使端部接合的橡胶构件接合装置。
背景技术
轮胎由作为片状橡胶构件的各种轮胎构成构件制造。在轮胎制造过程中，例如，胎体帘布层围绕成形鼓缠绕。在这之后，通过接合装置使胎体帘布层的前端部和后端部彼此抵接并接合到一起以形成筒状胎体帘布层。作为这种接合装置，已知用于通过一对接合辊自动地将橡胶构件的端部接合到一起的装置（参见专利文献1）。
在现有技术的接合装置中，一对接合辊沿着橡胶构件的端部移动。橡胶构件的两端部由一对接合辊接合在一起。然而，利用该接合装置，由于两端部是在橡胶构件的表面中的一个表面上接合，因此两端部不能从两个表面接合到一起。结果，橡胶构件的两端部在一个表面上接合强度和另一个表面上的接合强度可能存在差异。因此，鉴于更牢固地接合端部，仍有提高的余地。特别地，近年来，需要确保橡胶构件的强度以响应轮胎轻质化的趋势。随着这种趋势，要求提高端部的接合强度。
另外，利用现有技术的接合装置，整个装置的尺寸大并且控制复杂。因而增加了装置成本。并且还需要用于安装装置的大空间。对应于布置接合装置作业所需的时间，接合作业的周期变长。还有一个问题就是，即使在没有使用接合装置的时候，由于接合装置仍留在轮胎成形装置中，因此接合装置占用空间。此外，由于接合装置的移动需要大量人力，因此难以在多个轮胎成形装置中共享接合装置。为了处理上述各问题，要求使橡胶构件的端部容易并且可靠地接合。
作为橡胶构件接合装置，还已知用于从橡胶构件的两个表面来接合端部 的装置（参见专利文献2和3）。
而且，这些现有技术的接合装置使用移动接合辊用的大尺寸机构。因此使得整个装置的尺寸大并且控制复杂。也就是，不能实现端部的简单接合，并且难以解决上述问题。
可通过使用多个接合装置而在橡胶构件的两个表面上接合端部。多个装置设置在成形鼓的外部和内部并且使多个装置同时运转。然而，这种类型的接合装置还是大。需要用于安装装置的大空间。此外，成形鼓的构造也变得复杂。结果，接合装置的成本变高。

具体实施方式
将参照附图说明本发明的橡胶构件接合装置（以下被称作接合装置）的实施方式。
本实施方式的接合装置是手动装置。接合装置使由橡胶形成的片状橡胶构件的端部抵接并且将抵接的端部接合到一起。通过手动地移动接合装置将橡胶构件的端部接合到一起。结果，制造出端部被接合到一起的橡胶构件（已接合的橡胶构件）。
待接合的橡胶构件是仅由未硫化橡胶制成的构件或由未硫化橡胶和其他构件制成的构件。橡胶构件由橡胶形成为片状。通过切割橡胶构件而形成 具有预定形状的橡胶构件。接合装置使橡胶构件的端部抵接并将抵接的端部接合到一起。使一片橡胶构件的端部或多片橡胶构件的端部彼此抵接。通过压接橡胶构件的端部将端部接合到一起。如果橡胶构件是轮胎构成构件（例如胎体帘布层或带束层），通过接合装置使橡胶构件接合。胎体帘布层和带束层由未硫化橡胶和帘线制成。以下，将以作为轮胎构成构件的胎体帘布层作为橡胶构件的示例来说明。前述胎体帘布层被用于机动车用的子午线帘布层轮胎（PSR）。轮胎构成构件（胎体帘布层）在未硫化轮胎的成型处理中围绕成形鼓的外周缠绕。通过使轮胎构成构件的两端部（前端部和后端部）接合，轮胎构成构件形成为筒状。
图1是示出用于形成未硫化轮胎的轮胎成形装置的立体图。
如图所示，轮胎成形装置1设置有圆筒状成形鼓2和用于接合轮胎构成构件90的接合装置10。接合装置10用在轮胎成形装置1中。接合装置10使轮胎构成构件90的端部91和92抵接并且将端部91和92接合到一起。通过在成形鼓2上使轮胎构成构件90接合，来形成未硫化轮胎。
成形鼓2被配置成轴心水平放置的状态。成形鼓2围绕轴心转动。成形鼓2的外周通过气囊等而扩大和缩小。成形鼓2是在未硫化轮胎的成形过程中支撑待接合的轮胎构成构件90的支撑体。轮胎构成构件90围绕成形鼓2的外周缠绕一周。轮胎构成构件90通过成形鼓2形成为圆筒状。圆筒状轮胎构成构件90被保持在成形鼓2的外周。成形鼓2由驱动装置（未示出）驱动。驱动装置通过马达使成形鼓2转动。成形鼓2使轮胎构成构件90转动。轮胎构成构件90转动任意转动角度和停止。
通过用未硫化橡胶覆盖帘线（未示出），形成轮胎构成构件90。轮胎构成构件90在表面的橡胶中上具有多个帘线。轮胎构成构件90由供给装置（未示出）供给并且围绕在成形鼓2的外周缠绕。在缠绕轮胎构成构件90前，预先在成形鼓2的外周配置内衬层。轮胎构成构件90的帘线沿着成形鼓2的轴心方向配置。轮胎构成构件90的端部91和92两者以没有彼此重叠但是彼此相对的方式配置。端部91和92以彼此平行的方式配置。具有预定间隔的间隙设置 在端部91和92之间。
接合装置10沿着成形鼓2上的轮胎构成构件90的端部91和92手动地移动。端部91和92通过使接合装置10移动而被接合到一起。此时，操作者通过手来保持接合装置10并且操作接合装置10。操作者通过使接合装置10移动来执行端部91和92的接合作业。
图2和图3是示出本实施方式的接合装置10的侧视图。图2示出当轮胎构成构件90待接合时的接合装置10。图3示出当轮胎构成构件90未处于待接合状态时的接合装置10。在图2和图3中，轮胎构成构件90以虚线表示。
如图所示，接合装置10设置有一对开/闭构件11和12、开/闭机构20、多个辊30、31、32和40以及卷入防止构件60。开/闭机构20使一对开/闭机构11和12打开和闭合。多个辊30、31、32和40被设置于开/闭构件11和12。接合装置10在通过使多个辊30、31、32和40在成形鼓2的外周上移动的情况下将轮胎构成构件90的端部91和92接合。此时，成对接合辊40在片状轮胎构成构件90的各相对端部91和92上滚动。伴随滚动，成对接合辊40使端部91和92彼此抵接并且将端部91和92接合到一起。卷入防止构件60压端部91和92两者并且防止端部91和92两者被接合辊40卷入。
一对开/闭构件11和12由框架形成，所述框架上安装辊30、31、32和40。一对开/闭构件11和12以可打开/可闭合的方式彼此连接。辊30、31、32和40由开/闭构件11和12可转动地支撑。在此，一对开/闭构件11和12由下开/闭构件11和上开/闭构件12形成。下开/闭构件11配置在成形鼓2和轮胎构成构件90之间。上开/闭构件12配置在轮胎构成构件90的外周侧。一对开/闭构件11和12以夹着轮胎构成构件90的端部91和92的方式配置。一对开/闭构件11和12配置在端部91和92的两个表面上并且沿着端部91和92手动地移动。
一对开/闭构件11和12在打开位置（图3所示位置）和闭合位置（图2所示位置）之间手动地移动。结果，一对开/闭构件11和12被打开/闭合。闭合位置是轮胎构成构件90的端部91和92接合到一起的位置。在闭合位置处，使一对开/闭构件11和12彼此靠近。辊31、32和40夹持轮胎构成构件90。打开位置 是当端部91和92被配置在一对开/闭构件11和12之间时的位置。在打开位置处，一对开/闭构件11和12分离开。在打开位置处，辊31、32和40对轮胎构成构件90的夹持被解除。
开/闭机构20具有一对操作构件21和22、施力构件23以及连动机构24。一对操作构件21和22被分别连接到一对开/闭构件11和12。通过将开/闭构件11和12侧的端部中的一个端部用作支点来使一对操作构件21和22打开和闭合。一对操作构件21和22是用于使一对开/闭构件11和12打开和闭合的操作的把手。一对操作构件21和22由操作者手动地操作并被打开/闭合。一对开/闭构件11和12根据一对操作构件21和22的打开/闭合而被打开/闭合。一对操作构件21和22分别具有柄21A和22A。操作者抓握柄21A和22A以打开/闭合一对操作构件21和22。此外，操作者抓握柄21A和22A以使接合装置10移动。
施力构件23由弹性构件（弹簧、橡胶等）制成（在此为螺旋弹簧）。施力构件23被设置在一对操作构件21和22之间并且被安装在操作构件21和22上。施力构件23以从闭合位置朝向打开位置的方式对一对操作构件21和22施力。一对操作构件21和22总是以朝向打开位置（见图3）的方式由施力构件23施力。当使一对操作构件21和22彼此靠近时，施力构件23将力作用于操作构件21和22。使操作构件21和22彼此分离的力作用在操作构件21和22上。借助于这个力，一对操作构件21和22被移动。当操作者把持柄21A和22A时，施力构件23收缩。一对操作构件21和22闭合。当操作者释放柄21A和22A时，施力构件23伸长。一对操作构件21和22打开。
连动机构24以与一对操作构件21和22的打开/闭合连动的方式使一对开/闭构件11和12打开/闭合。连动机构24具有柱状固定构件25、板状可动构件26和多个转动轴27、28、29A和29B。下开/闭构件11被固定到固定构件25的一端。一个操作构件（下操作构件）21固定到固定构件25的另一端。第一转动轴27使另一个操作构件（上操作构件）22的端部与上开/闭构件12的端部可转动地连接。上操作构件22和上开/闭构件12围绕第一转动轴27屈曲。上开/闭构件12安装在设置于固定构件25的第二转动轴28上。上开/闭构件12围绕第二 转动轴28转动。结果，使得上开/闭构件12靠近下开/闭构件11。此外，上开/闭构件12与下开/闭构件11分离开。
可动构件26通过第三转动轴29A和第四转动轴29B安装在一对操作构件21和22上。一对操作构件21和22由可动构件26连接。一对操作构件21和22通过围绕转动轴29A和29B转动而打开/闭合。当一对操作构件21和22被打开/闭合时，第一转动轴27移位。上开/闭构件12根据第一转动轴27的移位而围绕第二转动轴28转动。如上所述，当操作一对操作构件21和22时，连动机构24使一对开/闭构件11和12打开/闭合。
当一对操作构件21和22被打开/闭合时，上操作构件22的位置相对于下操作构件21改变。连动机构24以该述一对操作构件21和22的打开/闭合连动的方式改变上开/闭构件12相对于下开/闭构件11的位置。借助于连动机构24，一对开/闭构件11和12被配置在打开位置和闭合位置。
手动地操作开/闭机构20。开/闭机构20使一对开/闭构件11和12移动。开/闭机构20使一对开/闭构件11和12在打开位置和闭合位置之间打开/闭合。闭合位置是轮胎构成构件90的端部91和92所接合的位置。借助于开/闭机构20，一对开/闭构件11和12移动到打开位置。辊30、31、32和40分离开。在这种状态下，轮胎构成构件90的端部91和92被插入在一对开/闭构件11和12（辊30、31、32和40）之间。借助于开/闭机构20，一对开/闭机构11和12移动到闭合位置。使辊31、32和40与轮胎构成构件90接触。辊31、32和40夹持轮胎构成构件90的端部91和92。开/闭机构20具有锁定功能（latch function）。开/闭机构20使处于闭合位置的一对开/闭机构11和12固定在预定位置。
接着，将详细说明一对开/闭构件11和12以及辊30、31、32和40。
图4是下开/闭构件11的平面图。在图4中，示出从图2的箭头X方向观察的下开/闭构件11。在接合装置10附近的轮胎构成构件90用虚线表示。
如图所示，在轮胎构成构件90的端部91和92之间设置间隙。接合装置10沿着端部91和92在移动方向S（接合方向）上移动并且将端部91和92接合到一起。移动方向S是接合装置10（一对开/闭构件11和12）在接合端部91和92 的过程中移动的方向。轮胎构成构件90在接合部93处接合。
接合装置10在下开/闭构件11上具有移动辊30（30A、30B）、引导辊31（31A、31B）、接合辊40（40A、40B）以及引导构件13。一对移动辊30A和30B、一对引导辊31A和31B、两对接合辊40A和40B以及一对移动辊30A和30B在移动方向S上从前向后（图4中从右向左）依次配置。成对的辊30、31以及40以平行的方式配置或者以相对于与移动方向S垂直的方向倾斜的方式配置。辊30、31和40分别与轮胎构成构件90的端部91和92相对。辊30、31和40由轴构件33、34和35可转动地支撑。轴构件33、34和35安装在下开/闭构件11上。
在轮胎构成构件90待接合的过程中，多个辊30、31和40被配置在成形鼓2与端部91和92之间。辊30、31和40与下开/闭构件11一体地移动。辊30、31和40在端部91和92的表面上或者在成形鼓2的表面上滚动。此时，使圆筒状移动辊30与成形鼓2的外周接触。移动辊30在成形鼓2的外周上滚动。通过在移动方向S上的移动辊30而使接合装置10平滑地移动。
一对引导辊31具有圆筒状。一对引导辊31相对于引导辊31之间的中心线对称地配置。一对引导辊31的各轴心从中心线侧（内侧）向外侧、朝向移动方向S上的后侧（图4的左侧）倾斜。在端部91和92接合前，一对引导辊31在与端部91和92接触的状态下在各端部91和92上滚动。从滚动的引导辊31向轮胎构成构件90的端部91和92施加力。用于使端部91和92彼此靠近的力被施加于端部91和92。
一对引导辊31使端部91和92移位。端部91和92朝向一对引导辊31之间的中央移位。一对引导辊31使端部91和92彼此靠近。一对引导辊31在端部91和92接合之前牵引端部91和92靠近接合位置并且将各端部91和92引导至接合位置。此时，由通过借助于一对引导辊31产生的相对弱的力使端部91和92靠近。一对引导辊31对端部91和92进行定位并且通过引导接合前的端部91和92而准备使端部91和92接合。
下开/闭构件11具有引导构件13。引导构件13配置在轮胎构成构件90的接合前的端部91和92之间。这两端部91和92由引导构件13引导。引导构件13(参见图3)固定在下开/闭构件11和固定构件25之间。引导构件13与下开/闭构件11一体地移动。此外，引导构件13具有板状并且设置在下开/闭构件11的宽度方向(图4中的上下方向)上的中心线上。引导构件13在下开/闭构件11的移动方向S上从前向后直线地延伸并且被配置成在一对引导辊31之间通过。引导构件13的一端(后端)位于相邻的一对引导辊31和一对接合辊40之间。也就是，引导构件13的一端位于一对引导辊31和最靠近一对引导辊31的一对接合辊40之间。在此，引导构件13配置在超出一对引导辊31的、在一对接合辊40附近的位置。
引导构件13具有逐渐变薄的倾斜部13A。倾斜部13A形成在引导构件13的移动方向S上的后端。轮胎构成构件90的端部91和92在与引导构件13的侧表面接触的状态下相对于引导构件13移动。此外，端部91和92通过沿着倾斜部13A的移位而逐渐靠近。结果，引导构件13引导端部91和92。引导构件13还是用于定位轮胎构成构件90的两端部91和92的定位构件。端部91和92在接合之前由引导构件13定位并且被引导至预定位置(接合位置)。端部91和92在由一对引导辊31引导的情况下沿着引导构件13相对地移动。在这之后，端部91和92靠近接合辊40。
接合装置10利用接合辊40将轮胎构成构件90的端部91和92顺次地接合到一起。接合装置10在下开/闭构件11上具有两对或多对(在此为两对)接合辊40。这两对接合辊40的构造相似并且被并排配置在移动方向S上。接合装置10通过位于在移动方向S上的前后方的成对接合辊40使端部91和92连续地接合。
图5是成对接合辊40的平面图。在图5中，与图4相对应，轮胎构成构件90以虚线表示。
成对接合辊40中的每一个接合辊具有如图所示为的圆筒状。成对接合辊40中的每一个接合辊的一端分别由轴构件35支撑。成对接合辊40相对于轮胎构成构件90的接合部93(辊40之间的中央线)对称地配置。成对接合辊40的各轴心从接合部93侧（内侧）向外侧、朝向移动方向S的后侧（图5中的左侧）倾斜。接合辊40的轴心的角度Y形成预定角度（例如，5°到30°的角度）。角度Y是由接合辊40的轴心与垂直于接合部93（移动方向S）的方向所形成的角度。成对接合辊40被配置成使得其轴心的交点位于接合部93。
成对接合辊40具有在轴心方向上突出的多个突起41（41A、41B）。突起41被设置到成对接合辊40的相对的边缘部。多个突起41沿着接合辊40的边缘部以相等间隔形成。在成对接合辊40上设置相同数量的突起41。在成对接合辊40的接合部93侧，在周向上交替地设置突起41和凹部。凹部是突起41之间的部分。突起41和凹部以相同的节距设置于成对接合辊40。在成对接合辊40中，突起41和凹部交替地配置。一个接合辊40的突起41进入另一个接合辊40的突起41之间（凹部）。结果，这些突起41彼此啮合。成对接合辊40中的每一个接合辊通过啮合的突起41以相同的速度同步转动。
图6是接合辊40中的一个接合辊的平面图。在图6中，示出接合辊40的一部分（图6中的上部）的截面。
如图所示，突条T形成于接合辊40的外周。突条T形成为环状或者螺旋状。突条T在接合辊40的周向上延伸。突条T被配置在接合辊40（包括突起41）的整个外周。多个突条T并置在接合辊40的外周上。由于突条T的原因，接合辊40的截面形状形成为多个突出部并置的锯齿状。突条T形成为三角形截面。突条T的侧面在突起41侧的角度比在相反侧的角度大。突条T的侧面的角度是突条T的侧面和接合辊40的轴心之间的角度。接合辊40的各突条T被压向轮胎构成构件90的端部91和92。通过接合辊40的突条T来压端部91和92的预定范围。
成对接合辊40A和40B（参见图5）沿相反方向在倾斜的状态下被分别压向轮胎构成构件90的端部91和92。成对接合辊40A和40B对称地配置。此外，成对接合辊40A和40B在移动方向S上沿着端部91和92移动。成对接合辊40A和40B分别在端部91和92上滚动。随着接合辊40A和40B的滚动，端部91和92利用接合辊40A和40B的突条T而移位。同时，通过突条T压端部91和92。用 于使端部91和92彼此靠近的力作用在端部91和92上。结果，两端部91和92被牵引到一起。端部91和92在消除在端部91和92之间的间隙的状态下彼此抵接。同时，通过从接合辊40A和40B施加的压力对端部91和92的端面进行压接。来自接合辊40A和40B的啮合的突起41A和41B的力交替地作用于端部91和92。端部91和92的表面通过朝向另一端部交替地变形而拼接到一起。结果，端部91和92接合到一起。
图7包括示出轮胎构成构件90在接合之后的接合部93的图。图7A是接合部93的立体图。图7B是从图7A的V-V线箭头截取的截面图。
如图所示，轮胎构成构件90具有设置在橡胶中的多个帘线C。在端部91和92接合到一起的过程中，表面橡胶93W由突起41A和41B交替地拉伸。橡胶93W在端部91和92的表面上被局部地拉伸。结果，表面处的端部91和92与相对端部的表面交替重叠。接合部93以形成波形的方式接合。
如上所述，成对接合辊40（参见图4）使端部91和92（两端面）彼此抵接并且在将两端部91和92牵引到一起的状态下使两端部91和92接合。接合装置10通过下开/闭构件11的两对接合辊40使端部91和92的相同范围接合到一起。结果，端部91和92牢固地接合。接合装置10将端部91和92连续地接合到一起。轮胎构成构件90形成为筒状。此时，接合装置10还通过上开/闭构件12（参见图2）的接合辊40将端部91和92接合到一起。
图8是示出设置到上开/闭构件12的辊32和40的平面图。在图8中，上开/闭构件12以及接合装置10的一部分被省略。示出从图2的箭头X方向观察的辊32和40。在图8中，在接合装置10附近的轮胎构成构件90以虚线表示。
如图所示，接合装置10在上开/闭构件12上具有接合辊40（40A、40B）、加压辊32（32A、32B）、保持件50和51以及卷入防止构件60。一对加压辊32A和32B以及一对接合辊40A和40B在移动方向S上从前向后（图8中为从右向左）依次设置。成对的辊40和32被配置成相对于与移动方向S垂直的方向倾斜。辊40和32分别与轮胎构成构件90的端部91和92相对。
保持件50被配置在一对辊40的两外侧，保持件51被配置在一对辊32的两 外侧。保持件50和51各自的一端连接到上开/闭构件12。保持件50和51被配置成从上开/闭构件12朝向下开/闭构件11。轴构件35和36被安装在保持件50和51的另一端。接合辊40和加压辊32分别由轴构件35和36可转动地支撑。保持件50和51保持辊40和32。辊40和32与上开/闭构件12一体化地移动。在轮胎构成构件90待接合的过程中，多个辊40和32通过保持件50和51被配置在端部91和92的外周。在这种状态下，辊40和32在端部91和92的表面上滚动。
一对加压辊32中的每一个加压辊具有圆筒状。一对加压辊32被配置成关于辊32之间的中心线对称。一对加压辊32中的每一个轴心从中心线侧（内侧）向外侧朝向移动方向S的后侧（图8中的左侧）倾斜。一对加压辊32被平行地配置并且还与前述一对引导辊31相对（参见图2）。一对加压辊32在与接合前的端部91和92接触的状态下在各端部91和92上滚动。此时，加压辊32和引导辊31夹持轮胎构成构件90的端部91和92。一对加压辊32对与一对引导辊31接触的端部91和92施压。一对加压辊32将各端部91和92压向引导辊31。这种状态下，引导辊31如上所述地引导端部91和92。
与下开/闭构件11的接合辊40相似地构造成对接合辊40。然而，上开/闭构件12的接合辊40的直径比下开/闭构件11的接合辊40的直径大（参见图2）。关于突起41的长度，上开/闭构件12的接合辊40的突起41的长度比下开/闭构件11的接合辊40的突起41的长度长。上开/闭构件12的一对接合辊40被配置在下开/闭构件11的两对接合辊40之间。此外，上开/闭构件12的一对接合辊40被平行地配置并且还与下开/闭构件11的两对接合辊40相对。轮胎构成构件90的各端部91和92被分别夹持在上开/闭构件12的一个接合辊40和下开/闭构件11的两个接合辊40之间。
如上所述，在一对开/闭构件11和12中的每一个开/闭构件上设置成对接合辊40并且成对接合辊40被配置成彼此相对。此外，多对接合辊40夹持轮胎构成构件90的由一对引导辊31引导的各端部91和92。接合辊40在夹持各端部91和92的两个表面的状态下在各端部91和92上滚动。在此，接合装置10设置有与轮胎构成构件90的一个表面接触的两对接合辊40和配置在该两对接合 辊40之间且与轮胎构成构件90的另一个表面接触的一对接合辊40。也就是，接合装置10将所述两对接合辊40和一所述对接合辊40设置于一对开/闭构件11和12。接合装置10使端部91和92彼此抵接并且通过多对接合辊40使端部91和92彼此接合。端部91和92从轮胎构成构件90的两个表面同时接合。此时，成对接合辊40通过保持件50压向端部91和92。
图9是示出保持件50和上开/闭构件12的截面图。在图9中，图2中所示的保持件50的一部分和上开/闭构件12的一部分被放大地示出。
如图所示，接合装置10在上开/闭构件12上具有圆柱状连接构件52和弹性构件53。连接构件52将保持件50连接到上开/闭构件12。在保持件50和上开/闭构件12之间设置间隙。保持件50通过被连接构件52引导而移动。结果，使保持件50靠近上开/闭构件12。此外，保持件50与上开/闭构件12分离开。连接构件52例如由螺栓和螺母构成。螺栓被插入到设置于保持件50和上开/闭构件12的通孔中。通过将螺母旋拧至螺栓的前端而使保持件50以位移量可变的方式连接到上开/闭构件12。
弹性构件53由弹簧或橡胶（在此为螺旋弹簧构成）并且被配置成围绕连接构件52。弹性构件53设置在保持件50和上开/闭构件12之间。弹性构件53总是对保持件50施力。从上开/闭构件12朝向下开/闭构件11对保持件50施力。当轮胎构成构件90的端部91和92待接合时，通过接合辊40使保持件50朝向上开/闭构件12移位。此时，由于保持件50被弹性构件53往回推，接合辊40被压向端部91和92。结果，将端部91和92保持在被夹持在接合辊40之间的状态中。端部91和92从两个表面被可靠地接合。
一对加压辊32（参见图2）被保持件51压向端部91和92。与接合辊40的保持件50类似，也通过连接构件和弹性构件（未示出）对保持件51施力。由于加压辊32将端部91和92压向引导辊31，引导辊31可靠地引导端部91和92。
卷入防止构件60（参见图2、图3和图8）具有安装部61（在图8中省略）。安装部61被设置到卷入防止构件60的两端并且被安装到保持件50。卷入防止构件60通过安装部61被固定到保持件50。卷入防止构件60被设置于一对开/ 闭构件11和12（在此为上开/闭构件12）并且与保持件50和成对接合辊40一起移动。当成对接合辊40被压向轮胎构成构件90的端部91和92时，卷入防止构件60被压向端部91和92。卷入防止构件60被配置在一对引导辊40的移动方向S上的前方。卷入防止构件60与成对接合辊40一起移动并且压位于接合辊40的移动方向S上的前方的端部91和92。卷入防止构件60防止轮胎构成构件90的待由成对接合辊40接合的端部91和92被成对接合辊40卷入。
卷入防止构件60沿着成对接合辊40的外周配置。卷入防止构件60形成为与成对接合辊40的外周形状相适应的预定形状。卷入防止构件60形成为在中央部处弯曲的形状（例如，在平面图中为V字状或U字状）。卷入防止构件60的中央部被配置在成对接合辊40之间的中央线上。卷入防止构件60封闭了成对接合辊40之间的空间。卷入防止构件60的下端和成对接合辊40的下端位于相同的平面。
当成对接合辊40使轮胎构成构件90的端部91和92接合时，卷入防止构件60压位于成对接合辊40的移动方向S上的前方的端部91和92整体。卷入防止构件60压成对接合辊40的移动方向S上的前方附近的两端部91和92。结果，防止了接合前的端部91和92被滚动的成对接合辊40卷入。卷入防止构件60防止端部91和92被成对接合辊40之间的部分或被各接合辊40卷入。同时，防止端部91和92在成对接合辊40之间的空间中与突起41啮合。
接下来，将说明接合装置10使轮胎构成构件90的端部91和92彼此接合的过程。此外，将说明用于制造端部91和92被接合的轮胎构成构件90的过程。
首先，轮胎构成构件90（参见图1）围绕成形鼓2的外周卷绕一周。轮胎构成构件90的端部91和92以在成形鼓2的外周上彼此相对的方式配置。接下来，在轮胎构成构件90的边缘部94中的一个边缘部处端部91和92升高。边缘部94是轮胎构成构件90的位于成形鼓2的轴心方向外侧的侧部。结果，打开端部91和92并且将接合装置10设于端部91和92。
此时，一对操作机构21和22打开（参见图3）。利用该动作，一对开/闭构件11和12由开/闭机构20（连动机构24）打开。在使下开/闭构件11与成形 鼓2的外周接触之后，端部91和92下降到一对开/闭构件11和12之间。接下来，端部91和92配置在位于轮胎构成构件90的边缘部94处的引导构件13的两侧。依照引导构件13的侧表面来配置端部91和92。端部91和92分别与引导构件13的侧表面接触。接下来，通过闭合一对操作构件21和22，一对开/闭构件11和12由开/闭机构20闭合（参见图2）。结果，端部91和92被配置在一对开/闭构件11和12之间。此外，引导构件13配置在接合前的端部91和92之间。
接下来，使一对开/闭构件11和12沿着轮胎构成构件90的端部91和92手动地移动。端部91和92被夹持在引导辊31和加压辊32之间。此外，端部91和92被夹持在一对开/闭构件11和12的成对接合辊40之间。随着开/闭构件11和12的运动，辊31、32和40在端部91和92上滚动。此时，加压辊32将端部91和92压向一对引导辊31。端部91和92在被引导构件13引导的同时由一对引导辊31引导至通过接合辊40接合的接合位置。被引导的端部91和92彼此抵接并且通过一对开/闭构件11和12的成对接合辊40接合。这里，端部91和92被夹持在两对接合辊40和一对接合辊40之间。端部91和92从两个表面同时彼此接合。在上开/闭构件12的一对接合辊40即将使端部91和92接合之前，通过卷入防止构件60来压端部91和92。
接下来，接合装置10（参见图1）朝向轮胎构成构件90的另一个边缘部95移动。通过将接合装置10移动到超出边缘部95的位置而使整个端部91和92接合。在完成接合之后，端部91和92的与成形鼓2分离开的部分被压向成形鼓2。结果，使接合部93的形状平整。轮胎构成构件90形成为筒状。在此之后，另一轮胎构成构件被配置于接合后的轮胎构成构件90。未硫化轮胎形成于成形鼓2。对未硫化轮胎进行硫化以制造轮胎。
在上述接合装置10中，接合作业不需要复杂的控制，而是能够手动地接合轮胎构成构件90的端部91和92。此外，与现有技术的自动接合装置相比，接合装置10的构造变得简单。能够实现接合装置10的大幅小型化。结果，降低了接合装置10的成本，而且不需要用于安装接合装置10的空间。由于不再需要布置接合装置10作业所需时间，因此接合装置10能够立即开始接合。因 此能够减少接合作业的周期。当不使用接合装置10时，接合装置10不被保留在轮胎成形装置1上。因此接合装置10也不占空间。由于能够容易地移动接合装置10，因此接合装置10能够被多个轮胎成形装置1使用。通过使用上述接合装置10，能够容易地接合端部91和92。
端部91和92被夹持在成对接合辊40之间并且由成对接合辊40接合，在一对开/闭构件11和12中的每一个开/闭构件上均设置有成对接合辊40。因此，端部91和92能够从轮胎构成构件90的两个表面牢固且可靠地接合。而且还提高了接合后的轮胎构成构件90的强度以及端部91和92的接合强度。通过借助于开/闭机构20来开/闭一对开/闭构件11和12，端部91和92能够容易地配置在一对开/闭构件11和12之间。此外，辊31、32和40能够被精确地配置在用于接合端部91和92的位置。利用这种配置，端部91和92能够被辊31、32和40可靠地夹持。还能够精确地执行端部91和92的接合。
由于端部91和92被一对引导辊31引导到接合位置，端部91和92可被接合辊40平滑地接合。即使接合前的端部91和92的位置被改变，端部91和92也可由引导辊31引导到预定位置。因此，可减少端部91和92的配置精度的影响。此外，端部91和92可由接合辊40可靠地接合。通过借助于加压辊32将端部91和92压向引导辊31，能够更可靠地引导端部91和92。
因此，根据本实施方式的接合装置10，片状轮胎构成构件90的端部91和92可被手动地且牢固地接合。此外，轮胎构成构件90可被简单可靠地抵接和接合。由于各种轮胎的轮胎构成构件90可由一个接合装置10接合，因此接合装置10的多功能性变高。
通过借助于引导构件13引导接合前的端部91和92，可提高端部91和92的位置精度。结果，端部91和92可精确地彼此抵接。此外，端部91和92可精确地接合。引导构件13优选地配置通过一对引导辊31之间。另外，引导构件13的一端优选地位于引导辊31和接合辊40之间。在这种情况下，端部91和92能够通过引导构件13被精确地引导靠近接合辊40。因此，可进一步提高端部91和92的位置精度。
由于用于开/闭一对开/闭构件11和12的一对操作构件21和22设置于开/闭机构20，因此可容易地操作开/闭机构20。由于可通过一对操作构件21和22容易地开/闭一对开/闭构件11和12，因此还便于接合装置10的把持。在此，施力构件23设置于一对操作构件21和22。此外，一对开/闭构件11和12通过连动机构24以与一对操作构件21和22的开/闭连动的方式打开/闭合。因此，仅通过打开/闭合一对操作构件21和22就能够打开/闭合一对开/闭构件11和12。简化了一对开/闭构件11和12的打开/闭合操作（特别地，打开操作）。还提高了接合时的作业性。
可以在一对开/闭构件11和12的各开/闭构件上设置成对接合辊40。在这种情况下，轮胎构成构件90的端部91和92被夹持在两对接合辊40之间。即使这样，端部91和92也可从轮胎构成构件90的两个表面牢固地接合。然而，当两对接合辊40和一对接合辊40被如上所述地配置在轮胎构成构件90的各表面上时，可进一步提高端部91和92的接合强度。与本实施方式相反，可以将两对接合辊40设置于上开/闭构件12并且将一对接合辊40设置于下开/闭构件11。此外，两对或多对接合辊40可以设置于一对开/闭构件11和12中的每一个开/闭构件。可选地，一对接合辊40可以设置于开/闭构件11和12中的一个开/闭构件，并且三对或多对接合辊40可设置于开/闭构件11和12中的另一个开/闭构件。
成对接合辊40以使两外端部均位于移动方向S上的后方的方式相对于与一对开/闭构件11和12的移动方向S垂直的方向（下文称为正交方向）倾斜。成对接合辊40的外端部是位于成对接合辊40的正交方向外侧的端部。成对接合辊40以正交方向上的内侧部分比两外端部靠近移动方向S的前方的方式倾斜。与接合辊40类似地，一对引导辊31以两外端部位于移动方向S上的后方的方式相对于正交方向倾斜。一对引导辊31的外端部是位于一对引导辊31的正交方向上的外侧的端部。一对引导辊31以正交方向上的内侧部分比两外端部靠近移动方向S上的前方的方式倾斜。如上所述，成对接合辊40和一对引导辊31优选地相对于正交方向倾斜。此时，成对接合辊40相对于正交方向的 倾斜角优选地设置为比一对引导辊31相对于正交方向的倾斜角大。
引导辊31可以设置于上开/闭构件12而不是设置于下开/闭构件11。在这种情况下，加压辊32设置于下开/闭构件11。引导构件13可以设置于上开/闭构件12。上开/闭构件12的引导构件13被配置在接合前的端部91和92之间。
卷入防止构件60可以配置在多对接合辊40的全部（或任意部分）的移动方向S的前方。也就是，卷入防止构件60可以设置于下开/闭构件11。卷入防止构件60可以设置于下开/闭构件11和上开/闭构件12。然而，接合辊40的直径越大，端部91和92被成对接合辊40卷入的担忧就越大。仅需要将卷入防止构件60配置成靠近容易发生卷入端部91和92的成对接合辊40。如上所述，上开/闭构件12的接合辊40的直径比下开/闭构件11的接合辊40的直径大。在下开/闭构件11的接合辊40中不容易发生端部91和92的卷入。因此，卷入防止构件60优选地设置于上开/闭构件12的一对接合辊40。
在本实施方式中，通过使上开/闭构件12围绕第二转动轴28转动来打开/闭合一对开/闭构件11和12。另一方面，例如通过在与下开/闭构件11平行的状态下使上开/闭构件12移动，可以改变一对开/闭构件11和12之间的距离。如上所述，一对开/闭构件11和12可以通过彼此相对靠近或分离来打开/闭合。
通过接合装置10，轮胎构成构件90能够在除成形鼓2以外的支撑体上接合。例如，配置在平面支撑构件或运送装置上的轮胎构成构件可由接合装置10接合。此外，除胎体帘布层以外的轮胎构成构件可由接合装置10接合。
