SiroSilo Pre-programmed Robotic Case Erector
This pre-programmed robotic case erector capable of erecting, folding, and forming 30 cardboard boxes per minute, is taking China by storm.
8 sets of such box folding machines a Chinese domestic customer ordered were tested and packed on November 16, 2023.
These machines then took an extra-long trailer to the customer’s location.

Selling Points
Frame
Full carbon steel frame (surface sandblasted), net weight 620 kg, strong enough;
Safety door screw fastening holes are reserved on the frame, thus safety doors and interlock switches are optional for you to protect operators.
Box Blank Supply Storage
Tilt box blank magazine, blank traction relies on gravity and a push-down plate, without consuming electricity;
Proximity switch for box blank supply shortage detection.
Case Forming & Bottom Flap Folding
Frosted solid aluminum robotic arm with a strong aura;
Five powerful vacuum suction cups pick up and pre-break the carton blank at the same time, ensuring that the carton is square enough and does not fall off;
3 Inovance servo motors drive the robotic arm, clean and sharp box blank opening & shaping;
Fixed front minor flap folder and Taiwan AirTAC cylinder controlled rear minor flap folder leads to quick flap folding.
Box Bottom Sealing & Erected Box Outputting
As shown in the photo below, 2 Inovance servo motors drive the side belts, stable and reliable carton conveying;
High-quality pressure sensitive tape applicator, the tape fits the carton more compactly and without wrinkles;
Two Sick photoelectric sensors at the side belt entrance and center detect carton conveying, the erector automatically shuts down if no carton passes.
Control System
A simple & intuitive touchscreen control panel.
Specifications
Max. 30 cartons erecting in one minute;
Fast size changeover, averaging 2.5-3 mins.
9 Servo (30CPM/30s Size Changeover)
Overview
This carton box erector uses four more servo motors for automatic adjusting:
- Box Pressure Plate Height
- Blank Magazine Height
- Exit Conveyor Width
For carton size changeover, all you need to do is:
- Input carton dimension on the touchscreen
- Adjust the blank magazine width
- Place the limit block & limit nail against the box blank top
- Fix the push-down plate
The whole size changeover just needs 30-60 seconds.

Case Erector Manufacturer
Conventional carton erector manufacturers listed below are the top players in this niche.
When it comes to cobot case erector manufacturers, the top suppliers are:
Pre-programmed robotic box erectors released by SiroSilo are rare in the market, they abandon flexible programming and pursue high-speed carton erecting & forming.
They have captured the hearts of many well-known customers, including CJ Rokin Logistics, ZTO Express, GLP, Cainiao, China Post, JD.com, L’Oreal, P & G, etc.
Please enjoy the P&G carton erecting test on a SiroSilo pre-programmed robotic box erector.
Box Erector Machine Cost
The box erector machine cost depends on the following factors:
- Type (conventional/cobot/pre-programmed robot)
- Sealing media (tape/glue)
- Automation (semi-automatic/full-automatic)
- Carton size range (standard/customized)
Confirming the above factors is the 1st step in quoting the carton erector machine.
An automatic conventional corrugated box erector from an American manufacturer costs you $26,117.86.
This price is higher than any type of cardboard box folding machine you can find in China.
