Horizontal vs. Vertical Case Packers
Overview
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. |
