Hershey Creamery's High Density AS/RS 10 Years and Zero Days Downtime
In more than 10 years the automated storage and retrieval system
installed at Hershey Creamery Co. has not had a single down day.
In more than 10 years the automated storage and retrieval system installed at Hershey Creamery Co. has not had a single down day. Back in 1997, Pennsylvania-based Hershey Creamery Co., manufacturer of Hershey’s Ice Cream, sought Westfalia Technologies, Inc. (www.WestfaliaUSA.com) to design and build an automated warehousing system for their new ice cream distribution center in Middletown. The company was expanding its distribution as its original offices located downtown in Harrisburg were becoming too crowded, and couldn’t keep up with the company’s growth strategy.
Since 1894, family founded and owned Hershey Creamery has specialized in bulk ice cream novelties. The company distributes to more than 22,000 retail outlets such as grocery and convenience stores, but focuses mainly on direct-store delivery.
In 1997, in order to optimize material flow, reduce logistics costs and labor requirements, Hershey Creamery sought Westfalia Technologies Inc. to design and build a warehousing system for their new ice cream distribution center located in Middletown. The distribution center needed to handle the volume of smaller direct-store deliveries and larger orders for Hershey’s regional warehouses, while maintaining selectivity for numerous stock keeping units.
To accomplish the goals of optimizing material flow, reducing logistics costs and labor requirements, Westfalia designed and built a 5,000-pallet position, eight storage level automated warehouse system. The two-aisle system has a combination of seven- and five-deep storage lanes. Each aisle contains one S/RM capable of handling approximately 70 pallets per hour. All pallets are triple supported within the rack structure, thus eliminating pallet damage.
Parameters for the AS/RS design included: maintaining FIFO inventory management, one SKU stored in each storage lane, and the fastest moving SKU’s are placed in storage lanes as close to the input / output conveyors as possible. By storing the pallets in two different lane depths, the warehouse is able to meet the throughputs of the fast moving “A” products in the longer lanes, and the slower moving “B” products in the shorter lanes. This mix of lane depth also increases rack utilization. Westfalia’s design also enables pallets to flow directly from stretch-wrapping to the order selection area or shipping dock, as needed, especially during peak throughput conditions.
About five years later, to meet their growing distribution demands, the AS/RS was expanded -- aisle lengths were increased 50% and a 3rd level of pick lanes were added within the rack structure. At that time Westfalia’s Warehouse Control Software (WCS) was installed too. With these additions Hershey Creamery has been able to deliver its products faster and more efficiently.
Westfalia’s WCS manages and reports on the movement of all pallets and their cases throughout its journey in the warehouse. It issues a broad range of standard reports to keep track instantly of inventory and product flows.
Among the information gathered by the WCS at the pallet’s point of entry into the AS/RS is the SKU the pallet is carrying, height, weight, description, special storage classifications, shelf life, and the number of days a product can bypass FIFO delivery. An operator can easily add, change or delete this information.
Westfalia’s WCS has proven amazingly user friendly. With tab-style screens, in intuitive, an easy-to-read format operators quickly and easily learn how to use the system. And of course, Westfalia provided a full training package with the system installation.
As Mike Dubesky, control room operator, explains: ”While it’s a little overwhelming at first converting to automation, it doesn’t take long until you get used to it -- within a few weeks we were really comfortable.”
Ten years on, Hershey Creamery is extremely satisfied with its automated warehouse. “In all that time not a single day has been lost to down time,” states Tom Leonard, control room supervisor, “and we move 500 pallets a day in and out of here.”
In fact, Hershey Creamery is planning further upgrades to improve the efficiency of the S/RM’s now that their controls are 10 years old. With their continuous improvement efforts ice cream lovers everywhere can be assured their sweet treats will be ready and available when needed for years to come.
