具体实施方式
为了提高生产线的效率，最为直接的方式就是通过自动装置来取代手动人工，如图1所示为现有的工艺示意图，可以看出两个侧鼓之间区域的胶料是悬空的，没有支撑，无法进行自动贴合的，因此，针对这种状况，可以在侧鼓之间的主轴上设置一辅助装置来撑起胶料，使其满足自动贴合的要求，同时，由于在加工过程中，两个侧鼓需要相互靠近，因此该辅助装置也要满足不干涉侧鼓运动的要求，基于此，形成了本发明的技术方案。
以下结合附图对本发明做进一步详述：
如图2及图3和图4所示，本发明提出了一种成型鼓胎肩垫胶贴合辅助装置，该装置包括中间支架1、活塞杆2、支撑板3、驱动结构和翻起机构，其中，中间支架1用于套设在侧鼓之间的主轴上，同时，中间支架1上呈圆周状开设有若干滑槽4，活塞杆2则滑动插装在滑槽4中，驱动结构用于驱动活塞杆2沿着滑槽4进行滑动，支撑板3则能跟随活塞杆2同步运动，因此，当活塞杆2滑动的时候，能够带动支撑板3呈圆周状相对于中间支架1向外扩张延伸，从而对侧鼓之间区域的胶料进行支撑，而翻起机构则用于带动支撑板3相对于活塞杆2进行翻起，使得支撑板3在两个侧鼓相互靠近时可以翻转并拢，从而不干涉侧鼓的运动，避免影响生产线的正常生产。
在一些示例中，中间支架1上的滑槽4中安装有挡环5，活塞杆2上则套装有压簧6，并且压簧6的一端与活塞杆2的底部相接且其另一端与挡环5相接，当活塞杆2在滑槽4中没有滑动时，压簧6处于未形变的状态，一旦活塞杆2在驱动结构的驱动下，在滑槽4中发生滑动，压簧6变回发生形变，并且随着活塞杆2运动距离的正常，压簧6的形变越大，当驱动结构对活塞杆2的驱动力消除时，压簧6会恢复形变，与此同时，活塞杆2也会在压簧6的作用力下退回到滑槽4中，实现自动收回。
在一些示例中，驱动结构包括开设在中间支架1上的气路7，气路7与滑槽4相接中，并且气路7能够外接充气设备，从而通过外部的充气设备向活塞杆2的底面和滑槽4的内端面之间充气，通过气压顶起活塞杆2，使得活塞杆2在滑槽4中发生滑动，带动支撑板3相对于中间支架1向外扩张，支撑胶料。
在一些示例中，于活塞杆2的顶端固定安装驱动架8来承载支撑板3，同时，支撑板3的数量和活塞杆2的数量优选为2比1，即一根活塞杆2能够同时带动两个支撑板3运动，两个支撑板3能够更为充分的支撑胶料。
在一些示例中，于中间支架1上位于滑槽4两侧的位置处开设有导向槽9，同时在驱动架8的两侧固定接设有导向柱10，并且导向柱10滑动插装在导向槽9中，当活塞杆2沿着滑槽4运动时，导向柱10也能够在导向槽9中滑动，可以起到稳固结构以及运动导 向的作用。
在一些示例中，为了使支撑板3能够相对于活塞杆2进行转动，于驱动架8上转动安装有翻转支架11，同时进一步的将支撑板3固定在翻转支架11，此时，驱动架8与活塞杆2相对固定，、翻转支架11与支撑板3相对固定，因此，只需要带动翻转支架11相对于驱动架8翻转即可实现支撑板3相对于活塞杆2的翻转。
在一些示例中，翻起机构包括翻起气缸12和连接杆13，其中连接杆13与驱动架8相对固定，翻起气缸12的缸体转动接设在连接杆13上，翻起气缸12的伸缩杆则转动接设在翻转支架11上，因此当翻起气缸12的伸缩杆发生伸缩时，便能带动翻起支架相对于驱动架8进行转动从而翻起。
在一些示例中，于固定架上固定安装有销轴14，翻转支架11则转动接设在销轴14上，而连接杆13则固定在销轴14上，进一步的，在一些示例中，于销轴14上套装有扭簧15，并且扭簧15的一端接设在翻转支架11上且其另一端接设在连接杆13上，因此当翻起气缸12伸缩杆伸长带动翻转支架11相对于驱动架8进行转动时，扭簧15发生弹性形变，当翻起气缸12伸缩端回缩时，扭簧15也会逐渐恢复形变，翻转支架11也能随之回到原位，即使得支撑板3相对于活塞杆2回到原位。
在一些示例中，支撑板3为弧形板，可以更好的契合胎体复合件，提高支撑的效果。
综上所述，本发明的整体工作流程为：在胎体传递环将胎体复合件传递到成型鼓工位之间，该辅助装置的活塞杆2处于未伸出状态、支撑板3出去未翻起状态，当胎体传递环移动到成型鼓工位的时候，通过气路7向滑槽4中充气，使得活塞杆2向外滑动，支撑板3则仍不翻起，从而通过支撑板3对胶料进行支撑，贴合胎肩垫胶，胎胚定型之后，两个侧鼓会进行收缩，相互靠近，此时翻起气缸12启动，其伸缩杆伸长，推动翻转支架11相对于驱动架8进行转动，从而带动支撑板3翻起，避免支撑板3与侧鼓发生碰撞，然后等到胎胚所有工艺步骤完成之后，传递环接取胎胚，此时翻起气缸12放气，扭簧15提供复位扭力，使得翻转支架11和支撑板3一起回到原位，此后，放出滑槽4内的气体，利用压簧6带动活塞杆2复位，使得支撑板3收缩，等待下一个工作循环。
需要强调的是，本发明所述的实施例是说明性的，而不是限定性的，因此本发明包括并不限于具体实施方式中所述的实施例，凡是由本领域技术人员根据本发明的技术方案得出的其他实施方式，同样属于本发明保护的范围。
