Drop packers

A case is erected (usually in a separate machine), and the bottom flaps are sealed.  Bottles are collated, then dropped into the case.  The case exits the packer into a separate case sealer, where the top flaps are closed.   As you might expect, there can be issues with bottle breakage, especially with thinner glass.  A separate case sealer (and often case erector) is required, taking up valuable floor space.  


Wrap-around packers

The case is formed around the bottles as they flow through the packer. They are usually quite large machines that are best suited for dedicated product lines.


Pick & place packers

Similar to a drop packer, but the bottles are gripped by a robotic head, and lowered into the erected case.  To achieve the desired speeds, multiple heads are used to load two or more cases at a time.  A separate case erector and case sealer is usually required. Change parts can be expensive.




Case-over packer

At Hamson, we believe it makes more sense to move the case rather than the product during the packing sequence.  The case is pulled down (with mechanical grippers on the bottom major flaps) over the bottles, with the necks of the bottles providing a lead-in. This allows for tight packs, often eliminating the need for divisions.

The Hamson is totally self contained, with an integral case erector and sealer, making for a very compact machine - about 1 metre wide by 4 metres long.  





Labor reduction is usually the primary justification for going to automated  case packing; however, there are other factors beyond the simple return-on-investment calculations:



The Hamson Overpacker ST is best suited for packing bottles or cans, at speeds of up to 20 - 25 cases per minute.  In this market, there are several competing options, including:
