LFS Accumulating belt conveyor Accumulating conveyor transporting the pallets via a belt instead of a chain. LFS-LAT Conveying System 2

LFS Accumulating belt conveyor Construction principle of complete system Pallets Redirecting head Drive head with motor Aluminium profile system for top and bottom strand Frame in steel construction LFS-LAT Conveying System 3

Advantage 1: Serial operator protection due to belt principle • • • • Contrary to standard accumulating conveyors, the pallets are transported via a belt frictional connection not form closure The frinctional connection is precisely adjusted to the pallet and workpiece carrier weight during directional change That is why the pallet can be stopped by the operator in any given position Special safety devices such as housings, light grids or pressure mats are rendered obsolete LFS-LAT Conveying System 4

Frontal loading due to omitted protective housing • Loading from the side as is the case with standard accumulating conveyors which require a lot of space and cause a loss in conveying distance • Loading from the front of TÜNKERS belt conveyors in spacesaving and battery-like design LFS-LAT Conveying System 5

Advantage 2: Minimal energy needs • Standard accumulating conveyors: Energy dissipators! Each pallet is equipped with an independent friction unit. The motor output must be designed to correspond to the total friction of the pallets accumulated in front of the stopping points Workpiece carrier (5) (1) • Stopper Return transport of empty pallet (4) • As to the TÜNKERS belt conveyor, the pallets are mechanically decoupled from the belt when accumulating, only one remains in frinctional connection per stopping point • • • Motor design for = 1 + 5 + 4 pallets = 10 friction units Limitation of...

Patented pallet decoupling system* Functional principle: The pallet interlocks with the belt via a spring-loaded mechanism No positive fit but a frictional connection The retention mechanism can be unlocked with the release button Transport pallet with retention mechanism Guide profile Belt *) Patent: Leiritz Automation Tools Release button for retention mechanism LFS-LAT Conveying System 7

Detail: Unlocking function • When the pallets accumulate, the retention mechanism of the first pallet is unlocked. Only the last of the accumulated pallets is in frictional connection with the conveyor belt • The motor output only needs to be designed for the work of the frictional force of one pallet, even if there are several accumulating pallets STOP Accumulated Mechanism unlocked Mechanism in frictional connection Direction of conveyance LFS-LAT Conveying System 8
