20080210527 | POWER CONVEYOR WITH CORNER ASSEMBLY AND PALLET THEREFOR - A twin strand conveyor uses roller chains to move pallets along straight conveyor sections and an unpowered corner assembly that enables the pallets to glide around corners of the conveyor. The pallets are transferred from an upstream conveyor section into the corner assembly using a corner injection unit that includes powered rollers that lift the pallets off the roller chains an onto a set of ball transfers that support the pallets as they glide through the corner assembly. Side guides are used to direct the pallets around the turn and onto the downstream conveyor section. A pickup unit having powered rollers draws the pallets off the ball transfers and onto the roller chains of the downstream conveyor section. The rollers of the corner injection unit and pickup unit can be powered by the same motor used to drive the chains of the respective conveyor sections. | 09-04-2008 |
20090020397 | CONTAINED DRIVE SYSTEM FOR CHAIN CONVEYOR BELT TO REDUCE CATENARY SAG - A conveyor frame assembly for use with a conveyor belt formed from individual links each joined together at pivot points.
