Higher Quality, Higher Productivity, From The Most Advanced Technology.
Today’s market requires that you offer your customers more while keeping production costs at a minimum. With the Bestech Series, Akiyama is meeting your need for efficiency in short-run production, and combines it with the value-added enhancements that provide speed, quality, and flexibility.
Stable high-speed feeding, accurate registration, and smooth infeed on the widest range of stock
The pickup sucker is a piston type that is mechanically actuated, ensuring stabilized sheet feeding at operating speeds up to 13,000 iph. Height adjustments can be safely and easily made during the run.
Unique air separation feature lets you run virtually any stock – from lightweight stock to cardboard – at maximum speed.
The forwarding suckers can also be adjusted up or down, left or right, independently, providing positive and scratch-free feeding of sheets from lightweight stock to cardboard.
Non-stop feeder is standard
A tape slowdown mechanism reduces sheet speed by 40% to ease sheets into the front steps.
Venturi air gently assists sheet into the front headstops.
The swing mechanism has an upward motion allowing the swing to return to the front stops quickly after sheet transfer.
The result is longer lay time for sheet stabilization.
For special applications, optional features include static bars, air bars, and double sheet detector.
The Akiyama original cylinder configuration provides the following features:
Plate and blanket cylinders are normal size while the impression cylinder, which services two units has three working surfaces. The transfer cylinder has four working surfaces.
Sheet transport is enhanced by the large cylinders which subjects the sheet to less bending. By reducing bending, a wider range of stock thickness can be transported better than on smaller cylinders.
Large cylinders also permit printing four colors with only two transfers during the printing process, greatly reducing the possibility of distortion and marking.
The three-surface impression cylinder is large enough that the sheet is never in contact with two blankets at one time, further reducing distortion potential.
Delivery from the impression cylinder is made after the sheet is released from the last unit blanket. This feature eliminates distortion at the last unit and allows for Akiyama’s “drumless” delivery.
Grippers and gripper bases are of ultra hardened steel for durability and accuracy of registration.
Needle bearings are used in the grippers on the impression and transfer cylinders, reducing friction between the gripper shaft and gripper holder.
The cylinder gripper tips are covered with a special material to prevent the possibility of a sheet slipping.
Control of ink/water balance
The field tested and proven Akiyama Inker System is configured to provide optimum control of ink and water to the plate using an integrated continuous dampening system.
Large diameter form rollers are a key element in the success of the Akiyama system.
Improved ink distribution on the plate is achieved with the application of three oscillator rollers in contact with the super large form roller.
Dampening solution feed to the plate is controlled by the operator at the delivery.
Individual unit ink ductor roller controls are located on the delivery.
Temperture Controlled Inker
Ink train and plate temperature can be critical in some applications, especially when running waterless plates. In response, Akiyama offers a system that maintains proper temperature by circulating water through the ink oscillating rollers.
Automatic Ink Roller Wash-Up
Remotely Controlled by the Operator from the delivery panel, the Akiyama wash-up system is simple and saves time with control of solution application and wash-up tray.
Controls and functions for the operator’s convenience
Akiyama Color Control(ACC)
The ACC console provides the operator with precise ink controls, lateral/circumferential register, storage of job information, and interface with other systems.
The Delivery Control Panel, In Addition to normal drive controls, includes as standard:
Unit selection of ink and water operation
Water feed controls and Water Flood Button
Feeder and impression off controls
Control of he variable speed delivery sheet slowdown roller
Volume controls for the delivery blowdown fans
Safety monitor for observation of press conditions
Ink ductor controls
Monitor for infeed, feedboard, and feeder
Versatility and efficiency with increased productivity
Bestech also offers the versatility and efficiency of aqueous or UV in-line coating.
Combined with Bestech’s unique cylinder configuration, a sheet can be coated with no additional transfer points. Extended delivery is standard with the system, providing ample space for IR or UV drying equipment.
The patented doctor blade continually removes all unused coating from the form roller, while fresh coating is supplied from the pan roller. The result is consistently smoother laydown.
Plus, Bestech offers a coating unit that can be off line without requiring clean-up.
It allows you to run coated and uncoated jobs in any sequence.
Fine lateral adjustment is made from a control on the operator’s side of the press, circumferential adjustment by a gear on the blanket cylinder. The nip adjustment between blanket and impression cylinders is easily regulated with Akiyama’s unique worm gear mechanism.
The benefits provided by these system features include:
Increased product value with the ability to furnish higher gloss and additional scuff resistance.
Faster turn-around time due to the drying characteristics of aqueous coatings.
Increased productivity with the elimination of racking and obtaining a coating in the same pass with printing.
Environmental improvement with the reduction or elimination of offset powder.
One-touch removal of the coating pan for easy cleaning.
Meeting the industry need for short runs and high productivity
The auxiliary sheet holder facilitates continuous sheet feeding during the print run.
Sucker Air-Speed Follow-Up Mechanism
Feeder Static Eliminator System
This system removes static electricity from the sheets as they are delivered from the feeder.
Suction-Tape Feeder Table
Anti-Curl System in the Infeed Section
Air is supplied via the opening of the infeed section to prevent the sheet from traveling beyond the specified position, while at the same time the gripper side of the sheet is flattened.
Remote Plate Cocking
Plate cocking for registration is precisely controlled from the console by digital electronics. This system cocks only the plate, not the plate cylinder – the same way an operator would.
U-cut Registration system
Register pins used in conjunction with aligned plate indents make the Akiyama registration system easy and extremely accurate.
Automatic Racking Board Inserter
Racking board insertion at high speeds by one operator is made easy with the automatic inserter.
Automatic Blanket Washer
The optional blanket washers, which are controlled from the delivery, position the cloth web and then wash the blanket.
Labor Saving Configurations
To better meet the needs of printers today, Akiyama offers different levels of automation. Regardless of the configuration chosen, the benefit is reduced makeready time, enhanced productivity, and higher quality.
Akiyama Color Control (ACC)
The ACC console provides the operator with the capability of adjusting ink and water balance and precise control of lateral/circumferential running register. The ACC computer uses plate scanner output and its own internal programs for refined color control.
Paper Size Preset System
Sheet size adjustments for the feeder separator, feedboard tail wheels, side guide, and delivery tail and side joggers are made from the console.
Impression preset system
Paper caliper input adjustments are controlled from the console.
