其中，所述驱动组件150固定安装在所述支撑板或所述中间连接臂120上，所述驱动组件150包括驱动轮155，该驱动轮155的外周面用于在分拣台的底座上滚动，使得驱动轮155在转动的状态下驱动所述旋臂单元b以所述固定支撑座组件a为中心进行公转；在所述旋臂单元b进行公转的状态下，所述自转支撑座130由所述传动机构140带动进行自转。
在本发明中，该装置可通过一个驱动组件150和传动机构140实现公转与自转，既有利于降低成本，又有利于降低控制难度。

在上述实施例中，该装置的驱动组件150可设置一个，也可设置多个。若该装置设有多个旋臂单元b，各个悬臂单元都可配置对应的驱动组件150进行整体或单独的驱动，各个悬臂单元也可共用一个驱动组件150进行整体的驱动。单独驱动时需要各个旋臂单元b可均设置各自的轴承支撑座113与中间轴112连接。
轴承支撑座113的设置数量也与旋臂单元b的数量有关，例如多个旋臂单元b共用一个轴承支撑座113，则各个旋臂单元b需同步公转。例如，在所述轴承支撑座113的安装数量为1个的情况下，所述轴承支撑座113具有与所述旋臂单元b的数量相同的对接部， 所述对接部与所述旋臂单元b的中间连接臂120连接或通过中间件连接。或者，在所述轴承支撑座113的安装数量与所述旋臂单元b的数量相同的情况下，所述轴承支撑座113具有1个对接部，所述对接部与对应的所述旋臂单元b的中间连接臂120连接或通过中间件连接。

在一些实施例中，如图6和图8所示，所述从动组件160包括从动轮162和从动轮支架161等，所述从动轮162安装在从动轮支架161上，所述从动轮支架161与所述端部支架122固定连接。具体地，从动轮162的中部穿设有从动轮轴163，该从动轮轴163可安装在从动轮支架161上，从动轮162在从动轮轴163上的固定可通过螺母164实现。从动轮162的外表面可为光滑的外表面，以减小摩擦力，以便该悬臂单元或整个装置进行公转运动。
在一些实施例中，如图4和图5所示，所述传动机构140包括：安装在所述固定支撑座110的中间轴112上的第一传动件141；安装在所述自转支撑座130的传动轴132的底部的第二传动件142；以及将所述第一传动件141和第二传动件142连接的传动连接件143。优选地，所述传动连接件143为同步带，可增强同步性，防止打滑，所述第一传动件141和第二传动件142为同步带轮，但不限于此，也可采用平带传动或者链传动等。
上述的传动机构140主要用于实现公转带动自转的目的，使得一个电机驱动即可完成公转和自转。传动机构以采用带传动为例，进一步地，为便于调节传动带143的松紧程度，如图9所示，所述传动机构140还包括张紧组件170，张紧组件170可位于中间连接臂120的中间位置。所述张紧组件170包括张紧轮172和张紧轮支架171，所述张紧轮172安装在所述张紧轮支架171上，所述张紧轮支架171上设有位置调节槽，所述张紧轮支架171通过安装在所述位置调节槽的调节螺栓175固定在所述中间连接臂120上。具体地，张紧轮支架171可为折型板，其与中间连接臂120连接的位置调节槽可设置一对，并具有一定的长度，以便通过调节螺栓175调整张紧轮支架171的位置，从而使得张紧轮172调整压靠传动带143的程度。张紧轮172可通过转轴安装在张紧轮支架171上，外侧通过垫片173和螺母164进行固定。优选地，张紧轮支架171可具有至少一个加强筋。
在一些实施例中，电控组件180可包括电控箱子、驱动器和钣金等，其可固定在中间连接臂120上。
本发明的分拣台用公转自转装置中，驱动组件150提供动力，驱动轮155旋转，带动 整个旋臂单元b围绕固定在中间的固定支撑座110旋转，实现公转；旋臂单元b实现公转后，由于固定在中间固定支撑座110上的同步带轮固定不动，而与自转组件连接的同步带轮跟随着公转，从而导致同步带旋转，进而实现与自转支撑座130连接的同步带轮的旋转，最终实现自转支撑座130的自转台131围绕传动轴132的自转。
根据本发明中的分拣台用公转自转装置，可获得的有益效果至少包括：该装置可通过一个驱动组件和传动机构实现公转与自转，既有利于降低成本，又有利于降低控制难度。
