Control via the Cockpit touch-screen

Via the user friendly touch-screen the operator controls the sheet handling based on his knowledge and experience. Yaskawa Levanto’s basic movement pattern is pre-programmed, but the skilled and experienced operator decides parameters like stack thickness, twisting angle, airing intensity etc from the Yaskawa Cockpit touch-screen.

The pallet is supplied to Yaskawa Levanto via a dual-level conveyor, which also removes the empty pallets.

The pile surface topography is scanned digitally with a new patented measuring process 

The scanner reads the pile surface topography with an optical reader. The registration is made, when the pallet is positioned correctly in the lifting table and controls the grippers’ moving pattern, when they separate the ream from the pile.

Twisting airing and separating

The grippers perform a patented diagonal twisting of both corners in the stack. The patented diagonal twisting copies the operators manual twisting, airing and separating working sequence.

The stack is lifted away from the top of the pile

After airing and separating the sheets, the stack is moved smoothly to the vibration table. Taps can also be used to separate different jobs on the same pallet.

Removal of waste sheets

Assuming that taps have been inserted to indicate areas with waste Yaskawa Levanto can remove waste to a waste container.

Back-plate with air-nozzles

Air can be blown between the sheets with a specially designed back-plate with segmented air-nozzles. The blowing capacity can be adjusted by the operator.

Vibration table with vibrating “clap-trees”

The vibration intensity and frequency can be adjusted from the touch-screen. The vibrating clap-trees secure that all sheets are pushed correctly into register.

Conventional ream-feeding

The vibration table is turned 180° so the robot, positioned behind the table, can feed the stack in the same way the operator does. 

ream feeding/integrated turning

The stack is turned by the robot in the feeding process and eliminates the need for pile-turning. A great advantage for cover printers. 

After being vibrated into perfect register the stack is transported automatically to a position next to the operator
