Box Folding Robot
As time passes, the box folding robot has become increasingly popular in various industries, particularly in packaging.
Two types of such robots are available on the market: programmable collaborative robots & preprogrammed robotic arms.
Cobot case erector speed is slower, but it erects multiple boxes of different sizes without a changeover.
It uses three-dimensional coordinates to locate different carton blank magazines, thus erecting several cartons of various sizes in one cycle.
A preprogrammed robotic case erector can work 30 cases per minute.
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 case erector.
Conventional cardboard box erectors cannot fully release their speed advantages due to frequent size changeovers, increasing manpower input & downtime.
Conventional Carton Box Erector
If your cartons have a single size suitable for high-speed erecting, choose a preprogrammed robot box erector like P&G Japan.
Sirosilo can customize both of them as per your request.

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 a 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.
- Place a certain number of carton blanks into the blank magazine;
- Press the Start button, the machine first adsorbs and pre-breaks a carton blank;
- Unfolds the carton blank into a rectangular shape;
- Automatically fold the bottom inner & outer flaps, and seal the middle seam between the two outer flaps with tape or apply hotmelt glue between the inner & outer flaps;
- The formed & bottom-sealed carton is then forwarded 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 human beings 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 case 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.
Tilted non-powered carton blank magazine, which can add carton blanks at any time.
5 suction cups grab carton blanks simultaneously, 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, with a flatter & 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 menus include Home, Manual Operation, Parameter Setting, Fault Record, Product Settings, and Switch Products, which are easy to operate.
Most Economical 2 Servo Drive (10-15CPM)
This most economical case erector equipment introduces two servo motors.
One unit completes box absorbing, pre-breaking, and forming;
The other one pushes the erected box through the 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:
- Carton size input on the touchscreen
- Box blank magazine width adjustment
- Adjust the limit block & limit nail against the box blank top
- Push-down plate placement
Then you can press the Start button; the entire size changeover process 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.

- BOPP Tape
Most commonly, there are as many suppliers of 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 popular among customers because of its environmental protection, anti-theft, and strong sealing properties.
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 Case Erector
No machine is flawless, and the cobot case erector is no exception.
What are its advantages and disadvantages, respectively?
Pros
Box folding 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 case erector takes up less space than a traditional carton erecting machine.
Stronger Compatibility for Blank Quality
While traditional carton box erectors require high-quality cartons, box folding robots easily handle slightly deformed cartons in high humidity because they use soft, high-suction vacuums to unfold box blanks.
Flexibility
Carton size changeover requires conventional corrugated box erectors to stop for several minutes, while cobot case erectors can continuously absorb and erect many different sizes.
It supports a wide range of carton sizes, and it is transferable on a forklift to different packaging lines.
Easy Operation
You may think that a programmable robotic case erector requires programming expertise to operate, but that is a misconception.
It introduces simple and efficient visual programming, and you can master programming in half an hour.
Quilter
With a simple structure and fewer mechanical parts, the erecting process of box erector robots is almost in the air, with only the bottom sealing in contact with the tape applicator, resulting in a low noise level.
No Changeovers
No changeover is a particularly significant advantage of the robot box erector, which avoids downtime.
Less Maintenance
The collaborative robot consists of fewer parts, which reduces the component failure probability and machine maintenance time.
Cons
The slow speed is the most significant disadvantage of the collaborative robot box erector; only 4-8 cartons are foldable in a minute.
