Automatic plate change raises new height of offset printing preparation time

This year's drupa set off a new wave of full-automatic version change. The synchronous automatic version change device can increase the rapid boot preparation time, which is a testimony to the direction of equipment automation control. Here are a few of the latest typical automatic plate changing devices on display.

Heidelberg: AutoPlate XL automatic synchronization version system

Heidelberg's fully automatic synchronous plate change system AutoPlate XL can automatically complete the operations including the exit of the old version, the entry of the new version, the alignment, the closing pressure and the tension under the control of the operating navigation system of the printing press. At the same time, the plate cylinders of all units will be transferred to the same phase during plate installation for simultaneous plate installation, so the overall plate change time can be shortened to about 1.5 minutes.
KBA: Drive Tronic SPC synchronous version change drive device

KBA's DriveTronic SPC system allows all printing plates to be replaced at the same time in less than a minute. It can synchronize parameter settings and blanket cleaning, etc. At the same time, DriveTronic's independent drive mechanism can replace the easy Components that are subject to wear and vibration, such as intermediate drive elements such as gears and clutches. According to KBA's tests, the system preparation time of equipment equipped with DriveTronic SPC devices can be reduced by 14%. On Drubba, during the live demonstration of KBA 106, 15 jobs were printed in 59 minutes and 36 seconds, and each job included a new record of 520 qualified sheets.

Gauss: Autoplate automatic plate changing device

Gaussian Autoplate automatic plate changing device can put the next live printing plate in the printing box on the printing unit when the printing machine is running or in standby. After the job is printed, the operator can start the plate-changing operation by pressing a button. It can change plates simultaneously on all printing units or several of them. The time for changing the version and the labor intensity of the operator are significantly reduced, and the registration is more accurate. The operator was liberated to complete other start-up preparation operations. It takes less than 3 minutes to replace the 8 printing plates on a four-unit M-600 web offset press without cutting the web.

Manroland: APL robot automatic plate changing system

APL (automatic version) is an innovative system launched by Manroland. It uses a 4-axis robotic arm manufactured by KUKA Robot Group. The positioning error is accurate to 0.01mm. The robot is installed on the paper guide of the ordinary printing machine. The robot arm of the automatic plate loading device holds a set of printing plates that have been placed in advance. Two vacuum nozzles take the printing plate out of the plate warehouse. Stretch out and place the printing plate where the plate clamping system takes over. The printing plate automatic positioning mechanism fixes the printing plate.

 Hand Stretch Film

Hand Stretch Film is used for manual pallet wrapping, auto part, wire and cable industries. Mini packing plastic wrap use for bandding, wrapping, protect items. It is waterproof, dustproof, moistureproof. The width of shrink wrap is from 40-500mm, the thickness is 10-25 micron, tensile force is 0.6 to 1.8 kg, elongation is 300% to 450%. Could make customized hand mini Stretch Wrap
