PURPOSE:To change-over the carrying stroke of material at will by providing plural feed cams of different shapes to the cam shaft of a transfer feeder allowing free sliding and making it opposed to the cam roller of a feed lever. CONSTITUTION:Plural cams 61-64 of different shapes are installed to the cam shaft 4 of a transfer feeder and a cam roller 11a of a feed lever 11 provided on the shaft 30 is made abutted to, for instance, the first feed cam 61. The piston rod 32 of a cylinder 31 is connected to the other end of the feed lever 11, and the cam roller 34a of an auxiliary feed lever 34 that supports the cylinder 31 is brought to abut to the first feed cam opposed to the cam roller 11a. Changing the third and fourth solenoid valves, cam rollers 11a, 34a are disconnected from the first feed cam 61 by operation of hydraulic cylinders 37, 40. Feed cams 61-64 are shifted by switching the first solenoid valve 74 and cam rollers 11a, 34a are made opposed to desired feed cams 61-64. By this way, carrying stroke of material can be adjusted at will. |
