Simple. Reliable. Remarkable.

Case Erectors

Case erectors are simple relative to other packaging equipment. Automatic case erectors convert case blanks into fully erected, bottom-sealed cases. Simple as that.

But if you’ve ever struggled with opening a case, getting a case square or removing a jammed case, you know making a case erector is easy to do but hard to do well. When you step up to an INSITE case erector—also occasionally referred to as a box erector or carton erector—you’ll notice how our work can make your work very easy and very fast.

Key Features of INSITE’s Case Erector

Your case erectors should produce more than just a bottom-sealed case. Cases should be reliably square and come at a reliable speed on a machine that is easy and safe to operate as well as unfailingly automatic. In other words, you should have a case erector you can trust. INSITE Packaging Automation’s box erector machines have been designed from the ground up with features designed to inspire trust.

Automated LxWxD path generation

INSITE’s proprietary, advanced motion control software makes it possible to automatically generate a robot’s path using only the outside dimensions of a case. Replace the mechanical mass found in other erectors with INSITE’s single, simple and reliable SCARA robot.

Opposing-cup case opening

A case erector’s first task is to open a case. Many box erector machines struggle to account for glue over-spray along the manufacturer's joint or the dreaded L-shaped case. In both situations, the opposing-cup effector on INSITE Packaging Automation’s case erector takes care of business.

Robotic pick and pass

Smart use of robotics on INSITE’s auto case erectors enables us to get rid of many of the parts and mechanisms in run-of-the-mill case erectors. We replace these parts and mechanisms with a reliable SCARA robot controlled via the Rockwell brand you know and trust. Goodbye to clunking, clattering, knocking, slamming, fiddling, fixing and finessing. Hello, simple!

Safety and ergonomics

We’ve gone out of our way to ensure your operators' safety and health when using INSITE’s case erecting equipment. The magazine infeed is easy to access and limits loading strain. The open-frame structure puts changeover points and sealing modules within easy reach. Governing bodies agree: INSITE Packaging Automation’s case erectors are ANSI/PMMI B155.1, ISO 13849 Category 3, and UL certified.

Active case squaring

INSITE Packaging Automation’s active case squaring feature means that photo eyes ensure all cases are squared before they are sealed. If a case is skewed, our case erectors’ independently driven side belts respond with a microburst of speed to adjust the case, making it square every time.

Durable & sanitary frame design

INSITE's box erector frames are robust, reliable and hygienic. Made from over-engineered tube- and plate-steel and designed with sanitary standards in mind, these frames are built to withstand a 20+ year packaging equipment asset life.

FAQ: Case Erectors

  • What is a case erector?

    A case erector is a case-forming machine that automatically forms, folds and seals cases from flat, or knock-down, corrugated blank. These efficient machines enable teams to save valuable time from having to construct cases during the product-packing process.

    Case erectors are known by many similar names such as case erector machines, automatic case erectors, automatic cardboard box case erectors, fully automatic case erectors, auto case erectors, robotic case erectors, case erectors and packers, case formers, case former machines, base case erectors and case erecting equipment.

    Additionally, some refer to these machines as box erectors and related terms, including box erector machines, box erector robots, automatic cardboard box case erectors, automatic box erectors, cardboard box erectors, cardboard box erector machines, carton box erectors and carton box erector machines. These machines are also known by the name carton erectors and related terms such as carton erector machines, automatic carton erectors, automatic carton erector machines, auto carton erectors, carton box erectors and carton box erector machines.

    Simply put, case erectors go by numerous names, with some favored in various geographical locations over others. We believe, however, that there is one brand name in the case erector industry that should truly matter to customers seeking out the best case erector: INSITE Packaging Automation.

  • Are INSITE’s case erectors fully automatic case erectors?

    Yes, INSITE’s case erectors are indeed fully automatic case erectors. Our automatic case erectors also utilize SCARA robot technology and may also be referred to as robotic case erectors. Additionally, because of the speed ranges they’re capable of, our auto case erectors may be referred to as high-speed case erectors or high-speed carton erectors.

  • How do I determine “machine hand”?

    INSITE determines machine hand by standing on the operator/HMI side of the box erector machine and observing the direction the cases travel. If the case blank moves from right to left as it’s erected and sealed, you are looking at a left-hand machine. If the case blank moves from left to right as it’s erected and sealed, you are looking at a right-hand machine. (See diagram.)

  • How do I determine “case hand”?

    6. Polycarbonate debris cover
    7. Operator side disconnect. (This is required by few customers for entry into the machine in jam clearing and removes power to the motor but not the drive. Removing power from the drive lengthens recovery time.) Our standard is a main disconnect that removes all power and is located on the enclosure over the magazine.
  • What makes INSITE’s case erector different from competing products?

    INSITE Packaging Automation’s case erectors offer a number of notable differences compared with competing products. The biggest difference is our machine’s simplicity. By replacing traditional mechanical movement with a SCARA robot, we’re able to drastically reduce the number of components that each machine requires.

    With fewer components comes improvements in usability, reliability, maintainability and other areas.

  • Why are case erectors sometimes referred to as carton erectors?

    As stated previously, case erectors are often referenced by a number of different names. For industry professionals with a lot of experience in secondary packaging, the most perplexing names have to do with the use of the term “carton” and related terms such as carton erectors, carton erector machine, carton erector and sealer, carton box erector and carton box erector machine.

    Let’s briefly explore the differences between boxes and cartons. Boxes are made from corrugated fiberboard, also known as corrugated cardboard or corrugated board. This material runs thicker than the material used to make cartons, as it comprises multiple layers of paper along with a fluted interior layer. Cartons are made from paperboard, which is usually a thin, single-ply construction and thicker than paper.

    In less-technical terms, you could consider boxes to be shipping-friendly whereas cartons are suitable for store-self products such as cereal or plastic wrap.

    Technically speaking, carton erector machine manufacturers are actually erecting paperboard carton material. For this reason, INSITE case erectors are technically not carton erector machines. Instead, INSITE box formers (another name for case erectors) form corrugated material into sealed cases.
