Kuka releases Mixed Case Row Palletizing (MXRP) cell

December 072012
December 7, 2012 - Kuka releases Mixed Case Row Palletizing (MXRP) cell  that can deliver efficiency gains of 40% or more in building same-store pallets.
MXRP combines RSW’s  adjustable-finger grippers and robotics to streamline the building of pallets with mixed products and/or packaging at distribution centers. True mixed pallets usually are comprised of uneven layers. Conventional mixed case palletizing cells can load no more than one or two cases at a time, whereas an MXRP with four adjustable fingers, or forks, can stack up to four cases at a time with great accuracy. Such an MXRP cell with its single robot can handle up to 1,400 cases per hour, depending on package type and size. Conventional cells employ two robots and yet still can only manage 1,000 cases per hour at most. 
The MXRP gripper with Flex Strap technology makes it possible to position adjustable fingers at different levels to grip stock and load it on top of uneven layers.  Responding to the geometry of each layer, the MXRP cell’s control system can adjust each finger independently, horizontally or vertically, and move forks left or right for optimal spacing. While the gripper can accommodate up to six forks (and load up to six cases at a time if so equipped), four-fork installations will suit most situations. 
By switching to MXRP, warehouse operators will realize substantial capital and operating economies as well as significant space savings. A recent beverage plant evaluation determined a six-cell MXRP layout would have the same throughput as a nine-cell layout employing conventional technology, but with a footprint at least 3,000 sq. ft. smaller than the latter. MXRP also produces a denser, more store-friendly mixed pallet. Often, store pallets are wheeled right off the truck into store aisles for overnight re-shelving. Fewer but denser pallets means faster unloading and positioning, and fewer obstacles in the aisles for late-night shoppers.
