GEAR-CAM SHEET DELIVERY MECHANISM

Pinche para ampliarPinche para ampliar Description

Gear 2 rotates about fixed axis A and meshes with gear 1 which rotates about fixed axis B. Face cam 7 rotates about fixed axis C and has profiled groove a. Follower 14 turns about fixed axis D and carries roller 13 which rolls and slides along groove a. Follower 14 has segment gear 8 which meshes with pinion 9, rotating about fixed axis E. Conveying bands 11 run over impression cylinder 15, rigidly attached to gear 2, and over roll 16, rigidly attached to gear 1. The mechanism is intended for delivering the printed sheets. When a sheet has been printed and its leading edge reaches wooden delivery roll 16, the grips open and the sheet is transferred from cylinder 15 to roll 16, over which conveying strings 3 run. Strings 3 carry the sheet onto fingers 4. Fingers 4 are mounted on shaft 5 which is rigidly attached to gear 9. As soon as a sheet reaches stops a on fingers 4, the fingers turn over the sheet and place it on delivery table 6. The motion of fingers 4 is controlled by cam 7 which is keyed to the main shaft of the press. Link 10 with weight 12 serves to maintain the tension of bands 11.
