Title: Paper feed cylinder apparatus of sheet-fed press
Inventor: URAKAWA HIDEKI
IPC: B65H5/12
Filed: 1983-07-25
Abstract: PURPOSE:To enable positive paper (sheet) feed even at a high speed, by making it possible to perform speed reduction at a paper gripping position and speed acceleration at a paper release position by providing a cam mechanism for increasing and decreasing the rotation of a paper feed cylinder during one rotation. CONSTITUTION:When a paper gripping pawl reaches this side of a differential plate by rotating the shaft 7 of a paper feed cylinder 7, the main roller 56 running in slide contact relation to the inner cam surface of the main speed accelerating and reducing cam 52 fixed to a cam stand 49 moves from the small diameter part 52b of the cam surface to the large diameter part 52a thereof to revolve a cam lever 43 to left around a shaft 42 while revolving the shaft 7 of the paper feed cylinder to right by the meshing of a segment gear 47 and a segment pinion 38. Because the revolving direction of the lever 43 is opposite to the rotary direction inherent to the shaft 7 of the paper feed cylinder rotating along with a paper feed gear 5, rotation is cancelled to reduce the speed of the paper feed cylinder.
