摘要： A rotary diverter can be operated at high speed to divert selected products from one conveyor to a vertically displaced second conveyor. The rotary diverter can have at least one rotary member with a plurality of radial arms. Each radial arm can have an end effector with a lifting platform. A timing belt may be coupled to each end effector to the rotary member in order to keep the lifting platform substantially horizontal. A control system is provided to control a drive mechanism for rotating the rotary member. As the rotary member rotates, the lifting platform of the end effector rises through the first conveyor to lift a selected product over the second conveyor. As the rotary member continues to rotate the lifting platform can then descend through the second conveyor to deliver the selected product upon the second conveyor. During operation, the control system can ensure that the lifting platform of the end effectors: (i) substantially matches the horizontal velocity of the first conveyor when they lift a selected product from the first conveyor; and (ii) substantially matches the horizontal velocity of the second conveyor when they deliver a selected product upon the second conveyor. This arrangement diminishes the amount of acceleration, deceleration and knocking that the selected products are subjected to during the diverting process, which reduces the risk of product misalignment.
摘要翻译： 旋转分流器可以高速运转，将所选产品从一个输送机转移到垂直移动的第二输送机。 旋转分流器可以具有至少一个具有多个径向臂的旋转构件。 每个径向臂可以具有带升降平台的末端执行器。 同步带可以联接到旋转构件的每个端部执行器，以便使升降平台基本保持水平。 提供控制系统来控制用于旋转旋转构件的驱动机构。 当旋转构件旋转时，端部执行器的提升平台通过第一输送器上升，以将选定的产品提升到第二输送机上。 当旋转构件继续旋转时，提升平台然后可以下降通过第二输送器，以将选定的产品输送到第二输送机上。 在操作期间，控制系统可以确保末端执行器的提升平台：（i）当它们从第一输送机提起所选择的产品时，基本匹配第一输送机的水平速度; 和（ii）当第二输送机在第二输送机上输送所选产品时，基本匹配第二输送机的水平速度。 这种布置减少了在转向过程中所选产品受到的加速，减速和敲击的量，这降低了产品不对准的风险。
