Selecting a Case Packer

Quick Links

Overview

Model V 30 Vertical Robotic Case Packer from ESS Technologies, Inc.ESS Technologies, Inc. case packers provide a high performance solution for collating and placing packaged products into secondary cases. The Model K 15 Automatic Horizontal Case Packer and Model V 30 Vertical Robotic Case Packer both offer high performance, a very small footprint, fast changeover, and ease of maintenance. But selecting the best solution for a given application depends on the type of product and the required speed. This application note compares the configuration and performance of horizontal and vertical case packers to aid in the selection of the highest performing solution.

Horizontal vs. Vertical

Case packers may be configured as horizontal case packers or vertical case packers, referring to how the product is placed in the case. As the names suggest, horizontal case packers collate product and then push the collated grouping into the open case, which is oriented on its side, while vertical case packers lower product into the open top of the case. Each method works equally well, but they are each suited to different primary product packages.

Application Notes

For example, vertical case packing is the best choice for products that may tip over easily if pushed, such as irregularly shaped bottles and loose tubes. Vertical case packers are also more effective on products that do not push easily, such as foil sachets. Horizontal case packers are ideal for rigid products that can be easily stacked and pushed, such as cartons or carton bundles, soaps, etc.
Other factors to consider when selecting a case packer include equipment footprint, speed, and equipment flexibility. Horizontal case packers tend to have a slightly smaller footprint than vertical solutions, but the robotic system offers more choices as to what shape the equipment footprint can take. This is an advantage for placing equipment into facilities with very narrow space or a space that is not symmetrical (such as L-shaped). Vertical robotic case packers tend to have an advantage of speed over horizontal case packers. Robotic solutions also offer increased flexibility in the size and configuration of products being case packed as robotic solutions require less tooling to change from one product size to another.
Operational considerations are also important. Both the K 15 and the V 30 offer fast, tool-less changeover, and both have a balcony design that provides easy access for machine maintenance or cleaning. Either solution requires only one person to operate the equipment, and in fact, one person could easily operate several identical lines or share time with other duties on the line. A touch screen interface allows the operator to quickly access information about the production speeds and overall system performance.
