Abstract: A system includes a mounting machine, a first transferring device, a second transferring device, a third transferring device, a sensor, a control device electronically connected to the second transferring device, and a catching device. The first, second, and third transferring devices are arranged in sequence along the flow line to transmit a plurality of products. The first sensor detects the plurality of products at a predefined location. The first control device controls the second transferring device to go from a flow direction of the flow line. The catching device is movable relative to the mounting machine and catches the plurality of products at the predefined location. The first transferring device transmits the plurality of products to the second transferring device along the flow direction, and the third transferring device receives the plurality of products caught by the catching device. The invention further offers a method for processing products.
