In daily production on Akiyama series presses, delivery faults are among the most common problems encountered by press operators and maintenance personnel. These Japanese machines feature a compact structure and high cost-performance ratio, with a special cylinder arrangement. During maintenance, attention must be paid to the bridge gear clearance; if not addressed in time, the consequences can range from impaired registration accuracy and print quality in minor cases, to prolonged downtime in severe ones.
I. Fault Symptoms: Incomplete stacking, sheets falling, skewed pile on the delivery table, and uneven powder spraying causing back-side smearing.
II. Cause Analysis: Deviation in the timing of the delivery chain and gripper opening/closing; improper powder spray volume or clogged nozzles; incorrect adjustment of the jogger mechanism; failure of the braking roller/suction wheel. Given the compact structure, high cost-performance ratio, special cylinder arrangement, and the need to pay attention to bridge gear clearance during maintenance, priority should be given to checking key components and standard parameters when troubleshooting.
III. Maintenance Guide: Calibrate the delivery gripper opening/closing and chain phase; clean nozzles and set powder spray volume according to paper weight; adjust the front and side joggers; inspect the suction wheel and braking roller.
IV. Daily Maintenance: Regularly clean the powder spray system; check delivery chain lubrication; set delivery parameters according to paper type.
The above methods also apply to models such as Bestech 428, Bestech 629, and Jprint. For practical operation, refer to the AKIYAMA console / automatic plate-changing system and on-site conditions. In complex cases, it is recommended to contact professional maintenance support via the printm.cn platform.
