Description

带束层传递环及其传递方法 技术领域
本发明涉及一种用于制造轮胎胎胚的带束层传递环、 以及应用此类带束层传递 环针对带束层夹持与输送方法进行的改进， 属于橡胶机械领域。
背景技术
目前使用的橡胶轮胎主要是由钢丝胎圈、 胎体组件和带束层一胎面组件构成。 在胎胚制备过程中， 通常采用带束层传递环实现带束层一胎面组件的制备与输送、 还包括将成型后的胎胚输送至卸胎工位以完成整个制造工艺流程。
如以下在先公开的专利， 申请号为 ZL02214652. 0 , 名称为带束层胎面传递环， 其包括有设置在传递环体上的 12组夹持爪， 驱动夹持爪的 12个气缸座均匀地分布 于传递环体上， 传递环体通过螺钉与床鞍相连接， 床鞍通过螺钉固定于底部的直线 导轨。
在上述带束层胎面传递环上， 全部夹持爪均匀地分布于夹持环体内径并通过气 缸驱动以沿径向伸出， 借助施加于带束层与胎面组件表面的抓取力加以固定。 下部 夹持爪在提供抓取力的同时， 还可提供向上的托力， 但是上部夹持爪仅能提供抓取 力， 由于带束层与胎面组件较重、 幅宽较大， 上部带束层与胎面组件不同程度地存 在着下垂现象。
而且， 受到现有表面结构与造型的局限， 夹持爪难以完全地贴合于带束层与胎 面组件外表面。 在输送过程中， 带束层与胎面组件断面并不是一个圆， 而是呈现不 规则的弯曲状， 当将带束层与胎面组件套设于成型鼓外周后， 就会局部层叠于成型 鼓表面、 整体组件的平整度不高， 进而影响到后续胎胚制造质量。
有鉴于此特提出本专利申请。
发明内容
本发明所述带束层传递环及其传递方法， 其目的在于解决上述现有技术存在的 问题而沿环体内径均匀地分布夹持爪的同时， 将上部夹持爪设置地多于下部的， 从 而增加上部夹持爪针对带束层-胎面组件的夹持力， 以实现长时间地保证所夹持胎冠 部位的真圆度， 进而保证所输送的带束层-胎面组件与成型鼓之间的同轴度， 提高后 续胎胚制造质量。
另一发明目的是， 提高按上、 下分组分布的夹持爪， 设置两组控制进气状态与 进气量的电磁阀， 从而实现控制同组夹持爪的同步性， 以保证夹持与输送状态的稳 定性。 发明目的还在于， 改进夹持爪的仿形设计， 通过增设端面的抓钉以增强与所夹 持的胎冠部位的抓取力量， 进一步地提高夹持与输送状态的稳定性， 并且能够适用 不同花纹、 规格的带束层 -胎面组件。
为实现上述发明目的， 所述的带束层传递环主要包括有：
连接于底部滑轨并可沿轴向往复滑动的环座， 在环座上承载有环体， 环体上安 装有数组由锁紧气缸驱动并可沿径向伸縮以夹持带束层的夹持爪。
与现有技术的区别之处在于， 夹持爪的夹持端面为弧形， 数组夹持爪的夹持端 面处于同一圆周上；
每一夹持爪的夹持端面的弧形长度相同， 并且均匀地分布于所构成的圆周上； 沿环体的水平中心线划分， 上部夹持爪的数量多于下部的。
如上述基本方案， 数组夹持爪的夹持端面为弧形， 能够更好地贴合于带束层-胎 面组件的胎冠部位， 使之断面形状接近于一个完成的圆， 即胎冠部位的真圆度较高。
在全部夹持爪的夹持端面均匀地分布于同一圆周的基础上， 相邻两组夹持爪的 间隙均相同， 且每组夹持爪施加于胎冠部位表面的抓取力更加均衡。
更为重要的是， 将上部夹持爪设置地较多， 能够提供给上部胎冠更多的抓取力， 从而减小上部胎冠因自重发生下垂而形成的弯曲度， 使得上部胎冠更加贴合于夹持 爪的弧形夹持端面、 有利于整体胎冠更接近于圆形。
因此， 当将带束层与胎面组件套设于成型鼓外周过程中， 组件与鼓的同轴度更 高、 而且组件不易于发生层叠现象、 组件表面的平整度更高。
考虑到带束层传递环内径尺寸的限制， 若将上部夹持爪设置地比下部的过多， 反而会形成上部与下部胎冠之间夹持作用力差别过大， 导致胎冠整体发生较大的变 形、 更不易于保持与成型鼓的同轴度， 因此可采取以下更为细化的改进措施，
即全部夹持爪的数量为奇数， 沿环体的水平中心线划分， 上部夹持爪比下部的 多 1个。
更为优选和更具实施性的方案是， 全部夹持爪的数量为 11个， 即上部夹持爪为
6个， 下部夹持爪为 5个。
为保证数组夹持爪在径向伸縮往复动作上的一致性， 应当尽量减少控制进气状 态与进气量的电磁阀的数量。 但是电磁阀的数量过少， 又会因输送距离远近的不同 而导致管路中气压的不均衡性过大， 从而影响到作用于胎冠表面夹持力的分布均匀 性， 因此本发明提出采取分组控制的相应结构， 即沿环体的水平中心线划分， 控制 上部夹持爪的数个锁紧气缸连接并受控于一个电磁阀， 控制下部夹持爪的数个锁紧 气缸连接并受控于另一个电磁阀。 上部与下部的锁紧气缸进行分组控制， 可有效地 保证锁紧气缸驱动夹持爪动作的同步性。
为辅助地提高作用于胎冠表面的夹持作用力， 以使得胎冠更贴合于夹持端面， 可在每一组夹持爪的夹持端面上， 设置有数个外凸的、 用于插入所夹持带束层表面 内的抓钉。
采用上述抓钉设计结构， 同时也能够适用不同花纹、 不同尺寸与重量的胎冠组 件对于夹持作用力的要求， 本发明所述的带束层传递环可用于更多规格胎冠的生产。
现有带束层传递环较普遍地采取整体式的铸件结构， 因此其自重较大、 加工精 度难以保证， 因部分部件的损坏即需整体地更换环体而造成生产与维护成本的提高， 对此本发明采取如下改进结构，
所述的环体包括有一对分别安装于环座两侧、 单独制造成型的左侧板和右侧板; 所述的锁紧气缸， 分别安装于连接在左侧板与右侧板之间的连接板上。
通过分别加工左侧板、 右侧板和连接板， 更易于控制部件加工精度。 并且在长 时间使用后， 某个部件发生损坏时可直接拆卸、 进行维修和更换。 基于上述带束层传递环结构的改进与应用， 从本专利设计构思出发还可实现如 下内容的带束层传递方法：
在制造轮胎胎冠的过程中带束层传递环沿底部滑轨轴向地往复滑动， 以实现带 束层一胎面组件的制备、 以及将带束层一胎面组件输送至成型鼓上。
与现有技术的区别之处在于， 沿环体的内径均匀地分布数组夹持爪， 由锁紧气 缸驱动并沿径向伸出夹持爪以夹持并完成带束层的输送；
夹持爪的夹持端面为弧形， 数组夹持爪的夹持端面处于同一圆周上；
沿环体的水平中心线划分， 上部夹持爪的数量多于下部的。
数组夹持爪均匀分布且以上部的多于下部的， 能够长时间地保证所夹持胎冠的 真圆度、 保证带束层与胎面组件与成型鼓的同轴度与表面贴合平整度。
更具显著优点与特点的改进方案是， 沿环体的水平中心线划分， 由一个电磁阀 控制连接上部夹持爪的数个锁紧气缸， 由另一个电磁阀控制连接下部夹持爪的数个 锁紧气缸， 锁紧气缸分组控制而可提高数组夹持爪动作的同步性。 其中， 在每一组夹持爪的夹持端面上设置数个抓钉， 在夹持并输送带束层的过 程中抓钉插入到带束层与胎面组件的胎冠表面内， 以提高夹持不同花纹、 不同规格 胎冠的牢固性。
综上内容， 所述带束层传递环及其传递方法具有以下优点：
1、 上部、下部夹持爪分组设置与控制，能够长时间地保证所夹持胎冠部位的真圆度， 进而提高后续胎胚制造工艺的控制精度与加工质量。
2、 分组控制的夹持爪有利于提高夹持动作的同步性、 保证夹持与输送状态的稳定。
3、 改进夹持爪的仿形设计， 通过增设的抓钉以增强夹持、 抓取力量， 进一步地适用 于不同花纹、 规格的带束层 -胎面组件。
4、 构成环体的主要部件可单独地制备加工，从而有效地降低装置更换、检修的成本。 附图说明
