Box Folding Robot

As time goes by, the box folding robot has become more and more popular in various industries, especially packaging.


Two types of such robots are optional on the market: programmable collaborative robots & preprogrammed robotic arms.

Cobot carton erector speed is slower than the conventional box former, but it erects multiple boxes of different sizes without changeover.

It uses three-dimensional coordinates to locate different carton blank magazines, thus erecting several cartons of different sizes in one cycle.


A preprogrammed robotic box folding machine can work 30 cases per minute, such a speed is even faster than a conventional carton box erector.

Conventional carton box erector, regardless of vertical or horizontal types, only folds and erects a single-specific carton, and needs to shut down for carton size changeover.


Conventional Carton Box Erector

For customers with a wide range of carton sizes, traditional box folding machines cannot fully release their speed advantages due to frequent size changeovers, increasing manpower input & downtime.

So whether you have a wide range of carton sizes or focus on the fastest folding speed, different box erecting robots can meet your requirements.

In case you have a wide range of carton sizes and can compromise on speed, go for a cobot carton erector;


If your cartons have a single size suitable for high-speed erecting, choose a preprogrammed robotic box erector like P&G Japan.

Sirosilo can customize both of them as your request, you are welcome to contact us by Email or WhatsApp.

What is a Box Erector?

The box erector converts the flat cardboard box blank into a formed carton with a sealed bottom & open top.


It completes the box blank pre-breaking, box forming & shaping, bottom flaps folding, and bottom sealing in one stop.

As a popular packaging machine, it is linkable to the upstream primary packaging machine, such as cartoner and FFS machine;

It can also connect with a downstream case packer, automatic carton sealing machine, and palletizing machine.

How Does a Case Erector Work?

The following five steps outline how a case erector works.

  1. Place a certain number of carton blanks into the blank magazine;
  2. Press the Start button, the machine first adsorbs and pre-breaks a carton blank;
  3. Unfolds the carton blank into a rectangular shape;
  4. Automatically fold the bottom inner & outer flaps, and seal the middle seam between two outer flaps with tape or apply hotmelt glue between the inner & outer flaps;
  5. The formed & bottom-sealed carton then forwards to the downstream equipment.


What is the Use of Case Erector?

Food, pharmaceutical, beverage, tobacco, daily chemical, electronic, and other industries often use cartons to package products.

Manual carton folding is not only time-consuming but also increases labor costs, the corrugated box erector can replace the human being to fold and erect cartons.


No Manual Box Folding Anymore

After introducing corrugated box erectors to these industries, large quantities of cardboard boxes are foldable each shift.

On the conveyor belt, these erected cartons go ahead to the downstream case packer, case sealer, case edge sealer, etc, which greatly improves the packaging speed and efficiency, and significantly cuts labor costs.

30CPM Non-programmable Robotic Arm Case Erector

If your daily demand for cartons is large and the speed requirement is high, we recommend you purchase a non-programmable robotic box erector, with a speed of up to 30 CPM and a carton size changeover time of 2.5-3 minutes.

3 types of such erectors are optional:

Best Selling 5 Servo Drive (30CPM)

With a full carbon steel frame (abrasive blasting surface treatment), and a net weight of 620 kg, solid enough.


Tilting non-powered carton blank magazine, which can add carton blanks at any time.


5 suction cups grab carton blanks at the same time, ensuring that the carton does not fall off.


5 servo motors with mature and stable performance, 3 servo motors control the robotic arm, clean and sharp blank erecting;

2 servo motors control the drive belts, stable and reliable carton conveying.


High-quality pressure sensitive tape applicator, the tape fits better on the surface of the carton, a more flat & beautiful bottom seal.


Simple operation and fast speed, erecting 25-30 cartons per minute.

Fast carton size changeover, averaging 2.5-3 mins, and with one-touch control on the HMI.

The touchscreen menu includes Home, Manual Operation, Parameter Setting, Fault Record, Products Setting, Switch Products, etc., which is very convenient to control.


Most Economical 2 Servo Drive (10-15CPM)

This most economical robot arm carton erector introduces two servo motors.

One unit completes box absorbing, pre-breaking, and forming;

The other one pushes the erected box through drive belts for bottom sealing.


Components controlled by pneumatic cylinders fold minor & major flaps.

30s Size Changeover 9 Servo Drive (30CPM)

Compared with the 5-servo model, it adds 4 servos for automatic adjusting:

  • Pressure Plate Height
  • Box Blank Magazine Height
  • Width between Two Side Drive Belts


When changing carton sizes, all you need to do is:

  1. Carton size input on the touchscreen
  2. Box blank magazine width adjustment
  3. Adjust the limit block & limit nail against the box blank top
  4. Push-down plate placement


Then you can click Start on the touch screen, the entire size changeover process only takes 30-60 seconds.

Conventional Carton Box Erector

The conventional carton box erector consists of:

  • Frame
  • Box Blank Magazine
  • Blank Pre-breaker
  • Bottom Flaps Folder
  • Guide Rail
  • Internal Tape Applicator/External Hot Melt Glue Applicator
  • Touchscreen
  • Pneumatic Control System
  • Electrical Control System
  • ……


With a more complicated structure, it is more time-consuming and labor-intensive to maintain compared to the erector robot.

Its bottom sealing media includes BOPP tape, water activated tape, and hot melt glue.

  • BOPP Tape

Most common, there are as many suppliers as human hair, spread all over the world.

  • Water Activated Tape

Few suppliers in China provide this type, and the American company Intertape Polymer Group is the leading supplier of such erectors (10 CPM).

2-4 CPM Chinese WAT corrugated box erector drives away many customers.

  • Hot Melt Glue

Case erector glue is becoming increasingly popular among customers because hot melt glue is environmentally friendly, anti-theft, and has a strong seal.

Some potential customers also dive deep into the conventional cardboard erector by searching for box styles:

  • Regular Slotted Container (RSC)


  • Half Slotted Container (HSC)


  • Overlap Slotted Container (OSC)


Pros and Cons of Cobot Box Erector

No machine is flawless, and the cobot box erector is no exception.

What are its advantages and disadvantages respectively?


Case erecting robots have the following 7 advantages.

Small Footprint

Machine footprint is a frequent concern for consumer goods manufacturers, who plan the layout based on the floor space of each machine on the packaging line.

A robotic random carton erector takes up less space than a traditional box folding machine.


Stronger Compatibility for Blank Quality

While traditional carton erectors require high-quality cartons, case erecting robots easily handle slightly deformed cartons in high humidity because they use soft, high-suction vacuums to unfold box blanks.



Carton size changeover requires conventional cardboard box erectors to stop for several minutes, while box erecting robots can continuously absorb and erect many different sizes.


The case forming robot supports a wide range of carton sizes, it is transferable on a forklift to different packaging lines.

Easy Operation

You may think that a programmable robotic box erector requires programming expertise to operate, but that is a misconception.

It introduces simple and efficient visual programming, you can master programming in half an hour.



With a simple structure and fewer mechanical parts, the erecting process of box erector robots is almost in the air, only the bottom sealing is in contact with the tape applicator, resulting in a low noise level.

No Changeovers

No changeover is a particularly significant advantage of the box erector robot, which avoids downtime.

Less Maintenance

The collaborative robot consists of fewer parts, which reduces the component failure probability and machine maintenance time.


The slow speed is the most significant disadvantage of case erecting robots, only 4-8 cartons are foldable in a minute.
