Abstract
The invention provides a conveying device and a conveying method. The conveying device comprises a plurality of conveying units (5), a plurality of detection units (6), and a control unit. The plurality of conveying units (5) are continuously arranged along a transportation direction of transportation objects (W), and the plurality of conveying units (5) are respectively driven independently. The plurality of detection units (6) are respectively arranged corresponding to the plurality of conveying units (5), and detect whether the transportation objects (W) exist on the corresponding conveying units. When the detection units detect that the transportation objects exist in the upstream sides of the transportation direction of the two adjacent conveying units and the transportation objects do not exist in the conveying units on the downstream side of the transportation direction, the control unit makes the two conveying units operate, and conveys the transportation objects on the conveying units on the upstream side of the transportation direction to the conveying units on the downstream side of the transportation direction. The above scheme can effectively prevent collision among transportation objects.
