Title:
CUTTER MOUNT SETTING DEVICE FOR ROTARY DIE CUTTER
Document Type and Number:
WIPO Patent Application WO/2011/016374
Kind Code:
A1
Abstract:
The object is to make it possible to rapidly position and secure a cutter mount relative to a knife cylinder of a rotary die cutter and to reduce wear of an inner end of an ejection member which contacts an ejector. Wooden patterns (22) in which punching dies (20) are embedded are attached to cutter mounts (18). First through holes (76) are formed in a knife cylinder (16), and first ejection bars (74) are attached in the first through holes (76). Second through holes (80) are formed in the cutter mounts (18) and second ejection bars (82) are attached in the second through holes (80). The first ejection bars (74) and the second ejection bars (82) are capable of abutting against each other. By pushing out the first ejection bars (74) by an eccentric cylinder (72), punched chips (a) held in the punching dies (20) can be ejected. Recesses (98) extending in the axial direction of the knife cylinder are provided in the inner openings of the second through holes (80). Even if the cutter mounts (18) move in the axial direction of the knife cylinder when the cutter mounts (18) are set, the first ejection bars (74) do not abut against the cutter mounts (18).
