具体实施方式
下面参照附图描述本发明的实施方式，其中相同的部件用相同的附图标记表示。在不冲突的情况下，下述的实施例及实施例中的技术特征可以相互组合。
本发明的转移织物线圈的方法中，使用到了3个零部件，如图1-图4所示的转移针，如图5所示的护针片，图6-11所示的缝口齿。
图1显示了本发明的转移针4a的立体图，转移针具有转移针主体41，在转移针主体41的头部(接触织物线圈的一端)具有转移部42。转移针主体41为细长薄片状，转移部42为弯曲状且偏离转移针主体41的轴线，优选地，转移部42为弧形，从转移针主体41端部逐渐变细，末端呈尖状。转移针主体41的尾部(远离织物线圈的一端)具有转移针凸起411，该转移针凸起411卡合到织物转移装置的转移盘上，推动和拉动该转移针凸起411，能够将转移针在径向上向内和向往移动，而且还能够上下移动，以进行织物线圈的转移。
图2显示了本发明的转移针4b的立体图，与转移针4a的区别是，其形状与转移针4a对称。在使用时，需要一对转移针4a、4b配合使用。具体地说，是转移针4a、4b贴合在一起。转移针主体41做成薄片状，也是为了两个贴合在一起时减少体积，更加环保。
图3显示了使用时的转移针4a、4b的状态图。转移针4a、4b各自的转移针主体41贴合在一起，而各自的转移部42形成一个凹槽，转移针凹槽43，该转移针凹槽43用于容纳织物缝合装置的缝口齿，缝口齿的作用和一般结构是本领域技术人员公知的，在此不再描述。
图4显示了本发明的转移针的另一个实施方式，与第一实施方式不同的是，转移针主体41具有一定厚度，从而在转移针主体41的头部能够开一个凹槽，即转移针凹槽43。转移针凹槽43同样用于容纳缝口齿。优选地，转移针凹槽43是不对称的，在凹槽的末端具有缺口，使得织袜针1的针头能更顺滑的滑入转移针凹槽43内(见图6)。转移针主体41的尾部(远离织物线圈的一端)具有转移针凸起411，该转移针凸起411卡合到织物转移装置的转移盘上，推动和拉动该转移针凸起411，能够将转移针在径向上向内和向往移动，而且还能够上下移动，以进行织物线圈的转移。
图5显示了护针片4c的结构。护针片4c用于与转移针4a、4b配合使用。护针片4c具有护针片主体45，护针片主体45前端(接触织物的线圈的一端)向下延伸有护针片夹持部46。夹持部46具有第一凸起461和第二凸起462，两者之间形成了凹陷463。护针片主体45和护针片夹持部46之间的结合处形成有护针片斜切部47。护针片夹持部从护针片斜切部(47)垂直向下延伸。
护针片主体45的后端(远离织物的线圈的一端)的下侧具有护针片凸起451。该护针片凸起451卡合到织物转移装置的转移盘上，推动和拉动护针片凸起451能够将转移针在径向上向内和向往移动，而且还能够上下移动，以进行织物线圈的转移。
护针片主体45下侧具有多个护针片凹槽452，以与织物转移装置的转移盘相结合。使用时，缝合针4a、4b插入两片护针片4c之间，位于两个护针片的护针片夹持部46形成的间隙内。
如图6所示，缝口齿6a具有细长主体61和卡合部62，卡合部62从细长主体61的上端延伸出，两者结合起来整体呈近似的7字形。细长主体61包括位于下端的针状部611和位于上端的支撑部612。
图7显示了缝口齿6a安装在齿座6e上的示意图。图8显示了缝口齿6a安装在齿座6d上的示意图。齿座6e和6d组成一个完整的圆形齿座。其中图3中的半个齿座6d是可以向下翻转180度，从而两个半圆形齿座整对齐。整体呈7字形的缝口齿6a安装在织物转移装置的齿座6e上，具体地说，通过卡合部62挂在齿座6e的槽上，细长主体61装在齿座6e的槽内，其中，支撑部612完全嵌入在齿座6e的槽中，仅仅针状部611暴露出来。相似地，缝口齿6b(在下面描述)安装在织物转移装置的齿座6d上。
要使得缝转移口齿6a、缝口齿6b更贴合的安装在齿座6e上，缝口齿6a的进一步的细节结构保证了该技术效果，下面参照图1和图4来描述。
如图9所示，支撑部612的高度H与齿座6e的高度相匹配，使得安装后支撑部612不暴露出齿座6e，仅仅针状部611暴露于齿座6e外。支撑部612的宽度W与齿座6e的槽的径向上的深度相匹配，使得安装后支撑部612的外表面与齿座6e的径向外表面相平齐，不内陷也不外凸，安装后的效果见图7。
卡合部62的下侧具有卡合凸起621，卡合凸起621和支撑部612之间就形成了一个槽，从而使得缝口齿6a能紧固地挂在齿座6e的槽上。卡合部62的上表面具有固定槽623，以与齿座6e相配合，使得缝口齿6a能紧固地连接在齿座6e的槽上。卡合部62的末端具有上翘部622，用于与齿座6e相卡合，从而使得两者接触地更加紧密。
图10显示了针状部611的结构。针状部611的外侧(安装到齿座6e上后径向朝外的一侧)具有针状部凹槽6111，该针状部凹槽6111用于在齿座翻转180度后对齐后，下方齿座上的缝口齿的针状部611能够搭接在上方齿座的缝口齿的针状部611的凹槽6111内，从而使得接下来的线圈转移更顺畅。
图11显示了另一个实施例缝口齿6b的结构，该缝口齿6b的细长主体61的外侧(安装到齿座6e上后径向朝外的一侧)具有缝合槽613，缝合槽613用于容纳缝头机的缝合针，两个缝合针交替缝合，从而将袜子的袜头缝在一起。
如图12所示，在使用时，缝口齿6a、转移针4a、转移针4b和两个护针片4c之间的位置关系。缝口齿6a插入转移针4a和转移针4b并在一起形成的转移针凹槽43内，转移针4a、转移针4b插入两片护针片4c之间的间隙内。
下面参照图13-图29来描述本发明的转移针的工作过程的示意图。如下以袜子为例来描述本发明，但是本发明也可以应用于其他织物。
图13-图16显示了本发明的方法的步骤S1的示意图：利用护针片将织物的织袜针上的织物的线圈下压一定距离，其中织袜针穿过两个相邻的护针片形成的间隙内。如图13所示，在织袜机织到最后一圈，织物3在织袜机的翻袜管2内，织物3的最后一圈线圈在织袜针1的针舌下。将护针片4c径向向内移动以位于织袜针1上方，使得织袜针1位于两个成对使用的护针片4c形成的间隙内的下方。
如图14所示，翻袜管2向上运动，同时，织袜针1也向上运动，织物3离开生克片201，靠近护针片4c。移动的距离为使得织袜针1位于两个护针片4c下方，其中转移针4a、4b位于位于两个护针片4上方。
如图15所示，将护针片4c径向向内移动，将转移针4a、4b径向朝外移动，目的是使护针片4c在线圈的上面，护针片4c往下移动时能使织袜针1上的线圈压到针舌下方。同时，将护针片4c上方的转移针4a、4b径向向外移动以不影响转移针1的上下行程。
如图16所示，将护针片4c、转移针4a、4b一起向下移动，令织袜针1穿过两个护针片4c之间形成的间隙。利用护针片4c压着织物3的线圈向下移动一段距离。
图17-图19显示了本发明的方法的步骤S2的示意图：将护针片移动到织物的线圈处，使得线圈卡在护针片的凹陷内。
在图17中，将护针片4c径向朝外移动，脱离织袜针1以不影响转移针的上下行程。可以使得转移针4a、4b之间的间隙和两个护针片4c之间形成的间隙上下对齐。
在图18中，将护针片4c、转移针4a、4b一起向下移动，使得护针片4c的凹陷463对准线圈。
在图19中，将护针片4c径向朝内移动，使得织袜针1位于两个护针片4c形成的间隙内，而且线圈位于护针片4c的凹陷463内。
图20-图22显示了本发明的方法的步骤S3的示意图：将护针片上移，带动线圈上移，线圈带动织袜针的针舌上翻，直至织袜针的针舌抵靠到转移针下缘。
在图20中，将护针片4c、转移针4a、4b一起向上移动，织物3的线圈被护针片4c向上移动，最后织袜针1的针舌也被护针片4c抬起，最终抵靠在转移针4a、4b下缘。
在图21中，将护针片4c径向朝外移开，可以移动到护针片4c的初始位置，以不影响转移针1的上下行程。
在图22中，将护针片4c、转移针4a、4b一起向上移动，此时织袜针的针舌翘起。
图23显示本发明的方法的步骤S4的示意图：移动转移针，使得织袜针的针头位于转移针的转移凹槽内。
在图23中，将转移针4a、4b一起径向朝内移动，使得织袜针1的针头部搭在在转移针4a、4b形成的转移针凹槽43内。
图24-图26显示本发明的方法的步骤S5的示意图：移动护针片到线圈下方，带动线圈上移，使得针舌合拢，线圈被转移到转移针上
在图24中，将护针片4c向下移动到织物3的线圈位置之下。
在图25中，将护针片4c径向朝内移动，使得织袜针位于两个护针片4c形成的间隙内，优选地，护针片4c的上缘抵靠在织物3的线圈上。
在图26中，将护针片4c向上移动，带动织物3的线圈向上移动，带动织袜针1的针舌向上合拢，从而织袜针1的开口合上。继续移动护针片4c，使得线圈转移到转移针4a、4b上。
在图27中，将护针片4c、转移针4a、4b一起向上移动，脱离织袜针1，这时，织物3的线圈套在转移针4a、4b上，而且下面有护针片4c托着，因此能牢固的套在转移针4a、4b上，从而方便后续的操作，例如织物的转移和翻转。
在图28中，织袜针1向下移动。
在图29中，将织袜针和生克片201移开，进行后续的操作。
以上所述的实施例，只是本发明较优选的具体实施方式，本领域的技术人员在本发明技术方案范围内进行的通常变化和替换都应包含在本发明的保护范围内。
