Case Packer

Case packer coordinates multiple functional modules to complete complex packing tasks. It includes the following key units:

Carton Forming Unit: Opens flat cardboard and forms it into cartons.

Arranging Unit: Organizes and groups the products to be packed according to a preset arrangement (e.g., 3×4) and quantity.

Filling (Carton Packing) Unit: Assembles the arranged products into the cartons.

Sealing Unit: Seals the cartons filled with products, for example, using self-adhesive or hot melt adhesive.

case packer is a piece of equipment used for automated packaging. Its main function is to automatically or semi-automatically pack unpackaged products or products already in small packages into cartons, plastic boxes, or pallets for transport, according to a predetermined arrangement and quantity, and complete the sealing process.

Types and Applicable Products of Case Packer

Grip-Type (Robot/Suction Cup Case Packer)

Suitable for: Bottled, boxed, bagged, fragile items, and products with high appearance requirements (medicine boxes, cosmetic bottles, snack bags); the most flexible option, preferred for non-standard export orders.

Side-Push Type (Horizontal Push Case Packer)

Suitable for: Rows of bottles and cartons; low impact force, does not scratch the outer packaging.

Drop Type (Gravity Case Packer)

Suitable for: Impact-resistant products, mineral water bottles, aluminum cans; simple structure, high speed; not suitable for fragile or soft packaging.

Case Packer Features & Benefits

Stable operation: Equipped with photoelectric detection and anti-leakage mechanism, products are neatly arranged, reducing problems such as misalignment and missing parts in packing.

Safety protection features: Equipped with safety railings, emergency stop, and fault alarms. Automatic shutdown is triggered in case of material jamming, reducing the risk of equipment and material damage.

Saves labor: Replaces manual packing by multiple people, reduces labor costs in the long term, and solves the problems of difficulty in recruiting workers and insufficient manpower for night shifts.

Improve packaging efficiency: Stable and continuous operation, with production capacity unaffected by human fatigue, effectively increasing the throughput speed of the entire production line.

Reduce breakage and damage: The flexible gripping and smooth pushing design reduces product scratches and collision damage.

Compatible with smart production lines: Supports signal connection to host systems and can be integrated into automated factories.

FAQ

What types of case packers are there?

case packers mainly fall into three categories: drop packers, side-push packers, and gripper packers.
Drop packers accumulate products and then release a load-bearing plate, allowing the products to fall freely into the carton. They are fast, easy to maintain, and suitable for regular, durable PET containers such as mineral water bottles and laundry detergent bottles.

Side-push packers use a flat-push method to push products in layers and groups into the side opening of the carton, providing better product protection. They are commonly used for packing regularly shaped products such as cigarette boxes, medicine boxes, and cosmetic boxes.

Gripper packers use robotic arms or suction cups to grasp products. They are highly flexible and can handle various shapes such as bottles, cans, boxes, and bags, and can even handle mixed packing of multiple products. They are suitable for irregularly shaped or high-end products.

How to solve the problem of poor carton forming in a case packers?

Poor carton forming is primarily caused by inadequate crease pressing or incorrect paper feeding. First, check if the crease rollers are pressing deeply and straight enough, then confirm that the cardboard is aligned correctly during paper feeding.

Creasing issues are the most common. Inadequate crease pressing or vibration of the crease rollers can cause misalignment of the flaps and scissor errors during carton forming. The solution is to adjust the crease depth to ensure clear and straight lines. If the carton flaps are misaligned, you can add a retaining line or reverse crease to the die-cutting base plate to assist forming.

Incorrect paper feeding can also cause crease tilting. Check if the guide rollers are vibrating and whether the speeds of the two conveyor belts are synchronized. A belt surface that is too smooth will not grip the cardboard tightly and requires regular inspection and replacement.

How to adjust the pressure rollers of a case packer?

Specific Adjustment Steps:

Inspection and Cleaning: First, turn off the power and remove paper scraps and oil stains from the crease rollers and surrounding area.

Pre-crease Roller Adjustment: Adjust the pre-crease roller gap to half the thickness of the cardboard. For example, set the pre-crease roller gap to 3mm for 6mm cardboard.

Creasing Roller Adjustment: Adjust the crease roller gap to 2-2.5mm to avoid excessive depth that could cause cracking.

Equipment Parallelism: Ensure the crease and pre-crease data of the printing press are parallel to avoid numerical deviations caused by long-term use.

Testing and Fine-tuning: Start the machine for a trial run and observe the crease effect. If cracking or poor forming occurs, gradually fine-tune the gap, retesting after each adjustment.

Common Problem Handling:

Carton Cracking: Check the cardboard moisture content (maintain 8%-10%), the folding endurance of the base paper, and adjust the crease depth.

Poor carton forming: Check the correction wheel pattern (slanted wheel + belt assembly or belt + straight wheel), and adjust the belt angle and creasing wheel pressure.

Equipment malfunction: Regularly check the wear of the creasing wheels and pre-pressing wheels, and replace damaged parts promptly.

Maintenance recommendations:
Clean the equipment regularly, avoiding the use of chemical cleaners.
Regularly lubricate critical parts, such as bearings and chains.
Regularly check and tighten screws to ensure stable equipment operation.

What are some precautions for the daily maintenance of a case packer?

The core of daily maintenance for a case packing machine is proper cleaning, lubrication, inspection, and tightening. For cleaning, wipe the surface with a damp cloth and clean critical internal parts regularly, but avoid using corrosive cleaning agents. For lubrication, apply appropriate lubricating oil to transmission components regularly according to equipment requirements. Inspection and tightening include checking all connections, electrical, pneumatic, and transmission components before starting the machine each day, and adjusting or replacing worn or loose parts promptly. In addition, regularly inspect the drive system and electrical system to ensure secure connections, undamaged wiring, and that they are kept dry. Operators must receive professional training and maintain proper maintenance records.

Sensor malfunction or false triggering

Symptoms: Inaccurate packing position, missing items, repetitive actions.
Causes: Dirty photoelectric/proximity switch; Misaligned installation position; Poor signal cable contact.
Solutions: Regularly clean the sensor lens; Calibrate the installation angle and distance; Check the wiring terminals for secure connection.
