OEMs, Robotic Suppliers Team Up to Streamline Changeovers, Cut Labor Costs for End Users
A market study paints a positive picture for the future of robots in the packaging plant, in particular food and beverage and pharmaceutical applications. See how companies like Delkor are implementing robotics into their packaging systems.
Delkor Systems takes robotic case packing path to quick changeovers
When John B. Sanfilippo & Son, Inc. (JBSS)/Fisher Nuts decided to move toward greater automation of case packing for its pouched nut products, it not only realized a savings in labor, but it also saved significantly on its material costs. The company was originally looking just for automated solutions to replace the manual case forming, packing, and sealing of both shelf-ready packaging (SRP) and standard RSCs at two of its plants. What it got were automated systems from Delkor Systems Inc. (See them at PACK EXPO Las Vegas, booth #C-4340) that provided the desired flexibility, along with a new SRP format with greater shelf appeal and less packaging material.
“Fisher Nuts was initially against changing the appearance of their packaging [a two-piece SRP], until they saw the Delkor Cabrio Case, which alleviated their concerns with its clean, pre-cut front and wrapped corners,” says Rick Gessler, director of marketing & strategic account management for Delkor.
The patented and patents-pending Cabrio Case® is a single-piece tray-hood SRP that has a lift-off hood and machine-cut front and side edges that ensure a clean edge when the hood is removed. According to Delkor, the case saves from 10 percent to 20 percent in corrugated materials compared to a typical tear-away case, and 10 percent to 50 percent compared to a two-piece tray-and-hood combo. Primary packages are loaded and shipped flat in the case to reduce shifting and settling of the products inside, but are displayed vertically. Primary packages can also be shipped vertically, if required, using another variant of the Cabrio Case. Fisher Nuts is using bleached linerboard for the case to achieve high-impact, wraparound graphics.
According to Mike Cannon, senior vice president of corporate operations for JBSS, the most appealing aspects of the Cabrio were customer acceptance of the format and cost reduction.
In the area of equipment, Delkor recommended a fully automatic robotic case packer, the MSP Series, for JBSS’ Elgin, Ill., facility. For its Elgin and Selma, Texas, plants, Delkor specified four semi-automated hand-pack systems, each equipped with one Trayfecta S Series dual-head case former and two Capstone F Series case closers, both from Delkor.
At the Elgin plant, the fully automated line begins with a KHS Innopouch K-400 horizontal pouch machine that fills bag sizes from 2 to 24 oz. at speeds to 125/min. From there, pouches are conveyed lying flat, single file, to the MSP Series case packer. Upon entering the cell, a Fanuc M-2iA delta-style robot uses a vision system to detect pouch orientation. It then realigns skewed and random-pitched pouches (up to approximately ±20 deg) and places them in groups of two or three—depending on final pack configuration—onto a continuous-motion conveyor. From there, the pouches are conveyed to a Fanuc M-710iC Series six-axis robot that picks up from four to six pouches at a time, and packs them into the Cabrio Case. When required, the robot can also rotate layers or individual pouches to interleave them in standard RSCs or FSCs (flange-seal wraparound cases).
End-of-arm tooling for the Fanuc M-2iA comprises a lightweight vacuum head that picks a full pattern by collecting pouches one at a time. Tool changeover for this robot is a simple, tool-less operation.
