Description
本申请要求2013年10月31日提交中国专利局、申请号为201310533618.X、发明名称为“驱动传送带的驱动装置、传送装置、导纱器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本发明涉及纺织机械领域，特别涉及一种驱动传送带的驱动装置、传送装置、导纱器。
由纺织机械生产或加工得到的纱线，通过纱线卷绕机卷绕形成卷装。通常，一根纱线是横动地卷绕在旋转中的络纱筒管上，以形成具有交叉卷绕纱线的卷装。
一方面，络纱筒管由驱动电机驱动而实现旋转，在旋转过程中，纱线随之往复卷绕在络纱筒管上。另一方面，在络纱筒管下方设置有导纱器，导纱器可沿络纱筒管的轴向方向横动，纱线穿过导纱器后卷绕在络纱筒管上。也就是，在络纱筒管旋转的同时，导纱器牵引纱线横向移动，纱线以与络纱筒管轴向方向呈钝角的方向卷绕在络纱筒管上。
导纱器的横向移动为一个往复移动过程。在一个周期中，导纱器在络纱筒管轴向方向的第一端得到一个加速度后，基本可以匀速横动，至络纱筒管轴向方向的第二端变向并得到一个反向加速度，反向匀速横动，朝向络纱筒管第一端移动，之后，在第一端反向。
参照图1，现有的一种导纱器包括直线导轨1、位于直线导轨1上的滑动件2，在所述滑动件2上设置有导纱指3，滑动件2接入一传送带4中。一驱动轮5与旋转电机(未示出)的转子连接，传送带4环套驱动轮5，旋转电机驱动驱动轮5带动传送带4转动，传送带
4牵引滑动件2在直线导轨1上移动。在滑动件2到达直线导轨1一端，通过切换旋转电机的旋转方向，实现滑动件2移动方向反向，进而实现滑动件2在直线导轨1上往复移动，纱线穿过导纱指3横向移动着卷绕在落纱筒管6上。
但是，在滑动件2到达直线导轨1的任意一端，切换旋转电机的旋转方向时，旋转电机的速度有一个从零逐渐增大直到匀速旋转的过程，相应的滑动件的移动速度也有一个从零逐渐增大到匀速移动的过程，因此滑动件2在直线导轨1两端的移动速度较小，这样纱线会在落纱筒管两端形成密集卷绕，卷绕质量较差。

图2是本发明具体实施例的驱动装置的剖面结构示意图。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
参照图2，驱动传送带转动的驱动装置包括：
杆状件10；
套设于杆状件10上的驱动轮11，在驱动轮11与杆状件10之间为滚动连接，如轴承连接，使得驱动轮11可环绕杆状件10转动，而且驱动轮11与杆状件10沿轴线方向亦可同步移动；
分别位于驱动轮11两侧的第一旋转电机21和第二旋转电机22，
所述杆状件穿过所述第一旋转电机21和第二旋转电机22；
位于第一旋转电机21和驱动轮11之间的第一接合盘31，所述第一接合盘31和第一旋转电机21的转子固定连接并且沿第一方向转动；
位于第二旋转电机22和驱动轮11之间的第二接合盘32，所述第二接合盘32和第二旋转电机22的转子固定连接并且沿与第一方向相反的第二方向转动，及
离合件12，离合件12位于杆状件10的中轴线上，用于驱动杆状件10沿轴向方向往复移动。
在具体实施例中，参照图2，离合件12驱动杆状件10沿轴向方向朝向第一旋转电机21移动时，使驱动轮11随杆状件10朝向第一旋转电机21移动，至驱动轮11与第一接合盘31紧密接合，由于第一接合盘31与第一旋转电机21的转子固定连接，则驱动轮11和第一接合盘31第一旋转电机21的转子沿第一方向转动；之后，离合件12再驱动杆状件10沿轴向方向朝向第二旋转电机22移动时，驱动轮11与第一接合盘31即时分离，之后随杆状件10朝向第二旋转电机22移动，至驱动轮11与第二接合盘32紧密接合，由于第二接合盘32与第二旋转电机22的转子固定连接，则驱动轮11和第二接合盘32随第二旋转电机22的转子沿第二方向转动转动，实现驱动轮11旋转方向的切换。而且，在切换驱动轮11的旋转方向，如由第一方向切换至第二旋转方向时，第二旋转电机已经处于旋转状态，驱动轮11能立即获得一个反向速度，在较短时间内实现移动方向的切换。
在具体实施例中，将该驱动装置应用到传送装置，传送装置的传送带环套在该驱动装置的驱动轮11上，具体地环套在驱动轮11的轮槽17中，在切换驱动轮11的旋转方向时，亦可实现传送带转动方向的切换。而且，传送带在切换转动方向时，可立时获得一个反向速度，在较短时间内实现移动方向的切换。
在本实施例中，参照图2，离合件12位于杆状件10的一端，离合件12包括电磁铁121、位于电磁铁121与杆状件10的一端之间的弹簧122，其中，电磁铁121与电源连接，与电磁铁121相邻的杆状件一端为软磁性材料。在其他实施例中，电磁铁121与杆状件10的一端之间也可为其他弹性装置。

使用本实施例的离合件12，通过切换电磁铁121通电、断电，能较好切换驱动轮11与第一接合盘31、第二接合盘32的接合、断开，进一步实现驱动轮11切换旋转方向。
在具体实施例中，电磁铁121固定在第一支撑件13上。弹簧122可以是与杆状件10的端面和/或电磁铁121连接，起到固定弹簧122的作用，避免电磁铁断电，弹簧122对杆状件10施加弹力时发生晃动而脱落。
在其他实施例中，离合件包括：位于杆状件一端的电磁铁，与电磁铁相邻的杆状件的一端为软磁性材料；与杆状件另一端面连接的弹性装置，该弹性装置可以是弹簧。弹性装置沿其形变方向的一端与杆状件的端面连接，另一端固定。
这样，当电磁铁通电时，杆状件受沿轴向方向的电磁力，弹性装置被拉伸而对杆状件产生与电磁力方向相反的弹力，电磁力大于弹
力，杆状件朝向电磁铁移动，至驱动轮与第一接合盘接合，电磁力保持两者的接合更加紧密；当电磁铁断电，杆状件受弹性装置的弹力作用，而背向电磁铁沿轴向方向移动，至驱动轮与第一接合盘分离，与第二接合盘接合，弹力维持两者的接合更加紧密。
在另一实施例中，还可以是，离合件包括：位于杆状件两端的电磁铁，杆状件的两端均为软磁性材料。两个电磁铁分别吸引杆状件朝向各自移动，对其中一个电磁铁通电，杆状件受吸引朝向通电电磁铁移动；对通电电磁铁断电，对另一个电磁铁通电，杆状件反向朝向另一通电电磁铁移动。交替对两个电磁铁通电、断电，实现驱动轮与通电电磁铁一侧的第一接合盘或第二接合盘接合。
在具体实施例中，驱动轮11的外圆周面具有轮槽17，传送带环套在轮槽17中。驱动轮11与第一接合盘31相对的侧面具有第一离合器盘，第一接合盘31与驱动轮11相对的盘面具有第二离合器盘，第一接合盘31与驱动轮11之间的接合为第一离合器盘与第二离合器盘之间的啮合。
相应地，驱动轮11与第二接合盘32相对的侧面具有第一离合器盘，第二接合盘32与驱动轮11相对的盘面具有第二离合器盘，第二接合盘32与驱动轮11之间的接合为第一离合器盘与第二离合器盘之间的啮合。
在具体实施例中，参照图2，驱动装置还包括：支撑第一旋转电机21的第二支撑件14，和支撑第二旋转电机22的第三支撑件15，杆状件10穿过第二支撑件14和第三支撑件15。
具体地，第一旋转电机21的定子212环绕转子211，转子211环绕杆状件10，定子212与第二支撑架14连接，杆状件10穿过第二支撑架14且与第二支撑架14之间为轴承连接，转子211相对该定子212环绕杆状件10旋转。第二旋转电机22的定子221环绕转子222，转子222环绕杆状件10，定子221与第三支撑架15连接，杆状件10穿过第三支撑架15且与第三支撑架15之间为轴承连接，转
子222相对该定子221环绕杆状件10旋转。第一支撑件13、第二支撑架14和第三支撑架15可固定在底座16上。在其他实施例中，还可以是：在第一旋转电机、第二旋转电机旋转时，杆状件可作为第一旋转电机、第二旋转电机的定子。
本发明还提供一种传送装置，所述传送装置包括上述驱动装置、套设于上述驱动装置的驱动轮上的传送带，传送装置还包括为传送带所套设的另一驱动轮，驱动装置驱动它的驱动轮带动传送带环绕两个驱动轮转动。当上述驱动装置的第一旋转电机和第二旋转电机的旋转方向不同时，通过切换驱动装置的驱动轮与第一接合盘、第二接合盘交替接合、断开，驱动轮的旋转方向在第一旋转电机的旋转方向、第二旋转电机的旋转方向之间切换，实现传送带传送方向切换。
本发明还提供一种导纱器，导纱器包括：直线导轨、位于直线导轨上的滑动件，滑动件可沿直线导轨移动；上述传送装置，滑动件接入到传送带中。
在具体实施例中，设置第一旋转电机的转子的第一方向与第二旋转电机的转子的第二方向相反。当离合件驱动杆状件沿轴向方向朝向第一接合盘移动，驱动装置的驱动轮移动至与第一接合盘接合，驱动轮受第一旋转电机驱动并按照第一方向旋转，传送带以第一方向转动，滑动件沿直线导轨基本匀速移动；当滑动件到达直线导轨两端，离合件驱动杆状件沿轴向方向朝向第二接合盘移动，驱动装置的驱动轮移动至与第一接合盘断开，与第二接合盘接合，驱动轮旋转方向反向而以第二方向旋转，传送带反向而以第二方向转动，进一步滑动件移动方向反向。如此施行，可实现滑动件沿直线导轨往复横向移动，穿过滑动件的纱线横向移动着卷绕在纱线筒管上。
与现有技术相比，使用本实施例的导纱器，滑动件在直线导轨两端反向时，第一旋转电机或第二旋转电机正以一定速度旋转，滑动件能立即获得一个反向速度，在较短时间内实现反向移动，避免纱线在落纱筒管两端形成密集堆积，提升纱线卷绕质量。
本发明还提供一种纱线卷绕机，包括上述导纱器。
虽然本发明披露如上，但本发明并非限定于此。任何本领域技术人员，在不脱离本发明的精神和范围内，均可作各种更动与修改，因此本发明的保护范围应当以权利要求所限定的范围为准。
