00:28 Speaker 1: This is a dual, full layer robotic palletizer in which it takes two product lines, moves ’em both, then creates full layers on each product, and then the robot will actually take full layers and drop ’em off onto the pallets.
00:46 Speaker 2: The customer came to us. The issue is needing to palletize in a small area with multiple products. So this solution provides the ability to palletize two different products and two different lines in a very small footprint.
01:01 Speaker 1: Cases come into the system on an existing conveyor system. We immediately gap them with a meter-spacer conveyor. And once the cases are gapped, we use an interlock selective turner to orient the cases, either narrow-side leading or wide-side leading. At that point we form rows, we push individual rows onto a intermediate layer table. Once we form an entire layer, we push the entire layer onto a full layer end of arm tool. The end of arm tool is a roller bed that retracts out to strip the layer onto the pallet. We build full layers on CDLR conveyor and discharged onto a shuttle car, which takes it to an existing stretch wrapper. The overall system output of this one is 45 cases per minute.
01:40 Speaker 1: One of the key technologies in this is the very complicated control system on this one here, this system uses a lot of photo eyes to monitor the position of all the boxes and the placement of the boxes as they move through the dual layer palletizer. The controls will actually help to create the full layer and then let the robot know that it’s ready to pick up a layer to move it onto the pallet.
02:01 Speaker 2: Because we’ve integrated all this stuff into a single GuardLogix platform, the customer needs one software package to maintain this system from a controls perspective, and because it’s on Ethernet, they can access the controller within their plant network, they can see the status of the devices because they’re on Ethernet also. So they have a high-level of visibility into the system.
02:22 Speaker 1: The key technologies in this project were the FANUC M-410 450-kg robot. We needed to go to the 450-kg robot due to the layer weights and the tool size. The end of arm tool is the most important part of this project. It is a full layer design that accommodates either narrow-side layers or wide-side layers due to spacing requirements, gathering requirements on the layer. Additionally, we have two-layer formers that are mounted on top of each other. That was a key design part of this project to minimize the amount of floor space required to palletize these cases.
