Soft cartons have low stiffness and are easy to collapse or tear during opening. We customise a vacuum-assisted suction cup system with a uniformly distributed adsorption force to avoid tearing the soft carton. At the same time, we add longer forming guide rails to extend the guiding stroke of the carton, which reduces deformation caused by excessive instantaneous tension, and improves the opening success rate.
The core components of our machines are all from top international brands, with a failure rate of less than 0.5%, so the daily maintenance is very simple. It only requires cleaning the suction cups, lubricating the components, and inspecting the air path filter cup every two weeks without the need for professional engineers to operate.
We offer a remote module for complexly designed machines. When the machine alarms or parameters are abnormal, engineers will diagnose program or parameter issues online and solve 90% common faults within 2 hours. This avoids the time for waiting for engineers, ensuring continuous production.
We offer standard-type and compact-type machines. Compact ones occupy only about 2-3 square meters and are suitable for workshops with limited space. If you need a more compact machine, our engineering team will assess your workshop and customise a modular transformation. We adjust the feeding device, the height of the carton outlet, and the position of the conveyor line interface to easily integrate the machine into existing production lines.
Our corrugated box erector can handle different types of cardboard cartons and supports adjusting carton size within a certain range.Â
Due to different densities and shapes, cardboards of different corrugation types have different cushioning and compressive resistance. The machine adjusts the friction wheel and controls the pressure of the suction cup to automatically adapt to the suction force and feed pressure. Whether it is the harder A flute or the softer E flute, it can be stably formed without crushing the cardboard.
The automatic case erector equips multiple safety protection devices. All the moving areas are installed with transparent protective doors to protect operator safety. Key areas install photoelectric sensors, and the machine will stop immediately and sound an alarm when detecting a fault. All safety designs comply with CE standards, helping your factory pass the safety inspection.
What Is An Automatic Case Erector?Â
The automatic case erector puts flat carton blanks into the machine and unfolds, shapes, and seals them through various devices. During this process, each carton maintains square, preventing downstream jams and downtime and increasing packaging efficiency. The automatic production method simplifies the packaging process, replaces the repetitive labor movement, and ensures high consistency of case erecting.Â
Main Components of Automatic Case Erector
Delivery SystemÂ
The carton blanks are continuously supplied to the separation station through a large-capacity horizontal silo. The silo replenishes cartons during operation without stop.
SeparatorÂ
The multiple separation retaining system enables carton blanks to enter the machine one by one and keeps the blank spacing correct. This prevents two or more caton blanks from entering at the same time, avoiding machine jamming.
Distribution SystemÂ
The vacuum suction cups of storage rack firmly grasp the two panels of the carton, ensuring the carton remains square to facilitate subsequent bottom sealing. Â
Fixed Page Turner and Push RodÂ
All the folding sheets fold when the carton stops to ensure the precise position and consistent angle of the folding cover. The push rod slides the carton into the exit side belt, minimizing the resistance and preserving the integrity of the carton structure.
Spring-type Side Safety BeltÂ
The synchronous motor with bilateral drive belts and the spring-loaded function adapts to width changes of the carton, maintaining a square base without flattening the carton when the bottom closing device is pulled.
How to Choose Automatic Case Erector?
Manufacture Requirement Â
The erecting speed of the automatic case erector needs to be compatible with the speed of the back-end boxing machine and sealing machine. If back-end machines have low speed, the high-speed case erector will cause box blockage and line downtime. If the backend machine is fast, the standard case erector can not meet the production demand.
Medium and low speed (≤ 15 cases/minute): Standard vertical automatic case erector has a basic structure and low cost, which can meet medium production scale of medium and small companies.Â
High speed (≥ 25 boxes per minute): Rotary or horizontal automatic case erector has multiple workstations to operate in rotation, suitable for large-scale production of beverages, dairy product industries and it replace 3-4 operators.
24-hour continuous production: The continuous production requires high durability of the machine.Our machine is equipped with high-temperature grade bearings and wear-resistant components, and the machine operates under heavy loads around the clock. The annual downtime due to failures is kept within 8 hours.
Carton CharacteristicsÂ
The material hardness, sizes, and flute types determine the suction device and forming path of the automatic case erector. Correctly matching the carton and machine ensures an opening box success rate of ≥99.5%, increasing the overall efficiency of the production line by more than 20%. We offer proofreading test for your carton before purchasing.Â
Thin and lightweight cartons: The vertical type carton opener can adjust the air flow of the vacuum suction cups to achieve soft movement, preventing Elastic, single corrugation carton from being crushed or torn, reducing the loss rate of packaging materials.
Heavy Cartons: for double corrugated and heavy-duty cartons, we recommend a horizontal automatic case erector with strong adhesive force and a more robust mechanical structure. It replaces the heavy physical labor of manual erecting and reduces the work-related injury risk.
Moisture-absorbing and deforming cartons: Machines with powerful vacuum system and thickened suction cups better fit the irregular surface of the deformed carton to achieve stable opening. Even during the rainy season, your production line can operate normally.
Production Line ConnectionÂ
Physical connection: The automatic case erector works cooperates with downstream packing, sealing and palletizing machine. When purchasing, the case exit height, direction and the rear conveying line should match the back-end conveying line.Â
Our technical team will assess your workshop layout and customize the box exit height and conveying direction, ensuring the equipment can be connected upon arrival and without renovating your production line.
Communication connection: The communication interface of the machine should support common industrial protocols and achieve interlock control with downstream machines. We customize the control plan according to your communication protocol requirements. This avoids modifying the modules and ading additional costs.
How Our Automatic Case Erectors Prevent Jamming?
Jamming is the most common issue in case erectors and directly affects the working efficiency of automatic case erectors. According to statistics, machine downtime caused by jamming accounts for over 40% of the total downtime, resulting in production loss and labor waste. We optimize the machine for the following four causes of jamming to help you improve production line efficiency.
Disorganized Stacks of Cardboard Blanks
The self-aligning guiding track at the entrance of the silo precisely aligns the cardboard blanks, ensuring each cardboard blank is in the correct position before being sucked in. This prevents empty suction during high-speed suction, which could lead to machine downtime.Â
Irregular Cardboard Blanks from SupplierÂ
The cardboard blanks provided by suppliers may have issues such as inconsistent indentation depth, edge burrs, warping, and adhesion. The highly flexible vacuum suction cups automatically compensate for the unevenness of the paperboard surface. This enhances the machine’s compatibility with cardboard and you don’t spend extra time screening cartons.
Excessive Mechanical Force
If the mechanical force is too strong when opening and folding the cover, the cardboard may tear. The machine uses a rotary folding mechanism and precisely controls the folding trajectory through a servo motor, avoiding the traditional linear impact. This eliminates the jamming during erecting and protects surface printings from being scratched and damaged.
Carton Deviation during ConveyingÂ
The conveying section equips a self-centering drive belt system. The movement trail of the mechanical linkage is consistent with the synchronized speed, ensuring cartons do not tilt or tip when entering the bottom sealing area and avoiding machine jams.
