What is a Case Erector?

A case erector is a case former machine, that converts the case blanks into fully erected, bottom-sealed cardboard boxes or folding cartons.

It is a kind of packaging equipment widely used in logistics, e-commerce, and distribution industries.

Corrugated Box Erector

This machine picks up a case blank from the blank magazine, then completes a series of processes such as case forming, bottom flaps folding, and bottom sealing, and then outputs an erected cardboard box or folding carton.

The outfeed corrugated box/folding carton is open at the top, and the other sides are sealed, they are ready for product loading by case packing machines or human hands.

case-erector-2

Two types of case erecting equipment are available:

  • Corrugated Box Erector
  • Folding Carton Erector

This page focuses on cardboard erectors.

Types of Cardboard Box Erector

There are many ways to classify cardboard erectors, SiroSilo supplies three kinds:

Conventional

According to the degree of automation, conventional cardboard erectors can be divided into:

Automatic

For the automatic case erector, you just need to place the cardboard box or folding carton blanks in the magazine in advance, no need for other manual intervention.

Regarding the above video, we summarize its workflow as follows:

  1. Case Blank Pickup
  2. Case Opening & Erecting
  3. Case Conveying
  4. Case Bottom Sealing
  5. Erected Case Outputting

Semi-automatic

Please watch the following semi-automatic carton erector’s demo video for reference first.

A worker picks up a box blank and shapes the blank to fully erected status.

Then, he places the erected case on the KDF (Knocked Down Flat) stand for bottom flaps folding, and pushes it to the top & bottom sealing station.

After the photoelectric eye detects the carton, the pressure sensitive tape head automatically seals the top and bottom of the carton.

pressure-sensitive-tape-head

Based on case erecting orientation, corrugated box erectors have the following two types: vertical & horizontal.

Horizontal

The horizontal case former integrates cams and con rods to control box blank picking up, flap folding, and carton conveying, its mechanical movements are fast, precise, and stable.

cam-and-con-rods-0

Its fastest speed can reach 50CPM, which is especially suitable for beverage and mineral water factories.

Vertical

As for the vertical case formers, air-driven cylinders perform their carton blank picking and flap folding, and their case erecting speed is relatively slow.

However, its various mechanical movements are gentle and the requirements for carton hardness are lower.

Horizontal vs. Vertical

Horizontal cardboard erectors’ initial investment is higher, but they have one advantage: they work stably at any speed;

Vertical carton box erectors vibrate during the box blank pickup process, vibration may lead to suction cup damage or loose parts, ultimately leading to more frequent maintenance.

However, many small and medium-sized enterprises still buy vertical ones because of the price.

Horizontal-VS-Vertical-Case-Erector-1

If divided according to sealing media, conventional cardboard box erectors include the 3 types listed below:

BOPP Tape

BOPP tape is the most common cardboard box bottom sealing media during the erection process.

Gum Tape

Carton box erectors that use gum tape for corrugated box bottom sealing are rare in the Chinese market.

The CE-10P WAT model released by the American company Intertape Polymer Group (IPG) adopts water activated tape for corrugated box bottom sealing.

Hot Melt Glue

Hot melt glue corrugated box bottom sealing is more environmentally friendly than BOPP tape, but the initial investment in the erector is higher because an additional hot melt glue applicator is essential.

Some potential customers also dive deep into the conventional cardboard erector by searching for box styles, let’s briefly introduce the corrugated cartons and their styles.

Cardboard boxes are usually made from a single piece of corrugated fiberboard by scoring & slotting the blank, allowing for folding.

industrial-corrugated-boxes

Industrial Corrugated Box

The cartons for the erector machine are slotted boxes, and the following types of slotted boxes are common on the market:

  • Regular Slotted Container (RSC)
  • Half Slotted Container (HSC)
  • Overlap Slotted Container (OSC)

Among them, RSC is the most popular.

RSC-Regular-Slotted-Case

RSC

The width of Regular Slotted Containers’ outer flaps is exactly half the width of the box, and the two outer flaps meet at the container center line.

regular-slotted-container-(rsc)-0

RSC is the world’s most common slotted box style due to its efficient and versatile design that minimizes waste.

HSC

Compared to the RSC containers, the Half Slotted Container (HSC) box lacks a set of top flaps.

half-slotted-container-(hsc)-0

After folding & sealing the HSC containers, its top is completely open, making it easy to load products and suitable for displaying loaded products to customers.

OSC

Its one-side outer flap overlaps on the other side outer flap by a width less than or equal to the container width.

When the overlapping width is less than the container width, we call it an Overlap Slotted Container (OSC);

overlap-slotted-container-(osc)-0

If the overlapping width is equal to the container width, we call it a Full Overlap Slotted Container (FOL).

Case Corrugating Quality

According to our previous experience, the quality of case corrugating affects the corrugated box erector’ effect.

Case-Corrugating-Quality-1

Some customers also found this problem, and after replacing the poor corrugating cases with better ones, they successfully solved the problem.

Because of this, we suggest you communicate with your corrugated box suppliers and remind them to take care of corrugating quality.

If possible, inspect large-scale production.

Erecting Speed

Generally speaking, a standard vertical carton erector forms 7-10 cases/min, and a standard horizontal corrugated box erector forms 15-20 cases/min.

If you have higher requirements for speed, we suggest you purchase a horizontal high speed case erector, its speed could reach 40-50 cases/min.

Sealing Types

Tape sealing & hot melt glue closure have their advantages & disadvantages.

  • Pros & Cons of Tape Sealing
  1. Lower price;
  2. Less power consumption;
  3. Easier maintenance;
  4. Tape quality affects sealing quality;
  5. Tape sealing can’t keep up with high-speed case forming;
  6. A roll of tape runs out faster than a tank of glue, more frequent tape replacement.
  • Pros & Cons of Hot Melt Glue Closure
  1. Higher efficiency;
  2. Glue replacement frequency is lower than tape replacement;
  3. Glue may block the hoses & nozzles;
  4. Over-spraying may occur, and more cleanup efforts.

You can decide which type to choose based on the above comparisons.

Automation Degree

As mentioned, there are 3 types of case former machines according to the degree of automation, manual, semi-automatic, and automatic.

Manual case former machines are rare on the market now, semi-automatic & automatic case former machines are common.

If your budget is sufficient, in favor of fast case forming speed, and your local labor cost is high, it’s better to choose a fully automatic cardboard box case erector without any hesitation;

If your budget is limited, no special requirement for case forming speed, and your local labor cost is within an acceptable range, then you can choose a semi-automatic carton erector.

Folding Carton Erector

A folding carton erector is a common packaging machine.

After picking up the folding carton blank from the blank magazine, it then separates & shapes the carton blank, folds the bottom flaps, closes the bottom, and finally outfeeds the folding carton.

The folding carton is open at the top after coming out from the erector, and then a downstream packaging machine or human hand can load the product into it easily.
