METHOD AND APPARATUS FOR REMOVING DRIVE PLAY IN DRIVING GEAROF MULTICOLOR PRINTING SHEET ROTARY PRESS

摘要

PROBLEM TO BE SOLVED: To consider an arbitrary operation state by eliminating a play in the drive device of a multicolor sheet-fed rotary printing press selectively performing sheet turning. SOLUTION: A prescribed drive position for changing over an operation mode is set and the connection of the clutch arranged in a vertical shaft is cut off between the input branch transmission devices 4, 5 from the vertical shaft in order to eliminate drive coupling and one region of a sheet-fed rotary printing press is fixed and a drive gear train 1 is cut off. The unifixed region of the sheet-fed rotary printing press is revolved corresponding to the plate mold or surface printing position of paper to connect the drive gear train 1 and the fixing of the fixed region of the sheet-fed rotary printing press is loosened and the shaft parts of the vertical shaft 3 are mutually located to connect the clutch 8 of the vertical shaft 3.
