V. Detailed Packaging Process: From Carton Unpacking to Palletizing
Taking a typical production line equipped with Marchi automatic carton unpacker as an example, the complete process is described as follows:
Step 1: Automatic Carton Unpacking and Forming
The operator stacks flat cartons into the vertical carton storage warehouse. After the equipment is started, the suction cup grabs a single carton, and the cylinder synchronously completes unfolding, folding four bottom flaps and pasting tape for bottom sealing. MCKX-50X stably outputs 8 to 10 formed cartons per minute in this process.
Step 2: Material Filling
Formed and bottom-sealed cartons are conveyed to the filling station. According to material characteristics, it can be connected with granule packaging machine, bag-given packaging machine, liquid filling machine and other equipment. For example, powder materials adopt screw metering filling, granule materials adopt measuring cup or electronic weighing, and liquid materials adopt piston filling machine.
Step 3: Automatic Carton Sealing and Strapping
Filled cartons enter the automatic flap folding and carton sealing machine to seal the upper flaps and paste tape. Then the strapping machine carries out tic-tac-toe or parallel strapping to enhance carton stacking stability.
Step 4: Palletizing System
Sealed and strapped cartons are sent to the palletizing station through the conveying roller table. The optional palletizer of Marchi adopts servo control, which can automatically arrange according to carton specifications and stacking types, and set the number of layers per layer, staggered mode and total layers. The whole process requires no manual intervention, realizing full automation from carton unpacking to palletizing.
VI. Customer Pain Points and Solutions
In practical application, users often encounter the following problems when choosing automatic carton unpackers, and Guangzhou Marchi provides corresponding solutions:
Pain Point 1: Production line shutdown caused by frequent material shortage or tape exhaustion
Solution: MCKX-50X automatic carton unpacker is equipped with dual alarm lights for carton shortage and tape exhaustion. Operators can supplement materials in advance without shutdown waiting, ensuring continuous operation of the whole line.
Pain Point 2: Too long adjustment time when switching cartons of different specifications
Solution: This model adopts a manual adjustment mechanism, rotating the handwheel to change the width and height limit, and the switching is generally completed within 3 to 5 minutes. If the production line needs to frequently change multiple carton specifications, it can be upgraded to a customized model with automatic servo adjustment.
Pain Point 3: Standard machines cannot be used for special proportion cartons (narrow-long, low-wide, short-high)
Solution: Guangzhou Marchi provides non-standard customization services. After users provide a specific list of carton specifications, the technical team designs special grabbing suction cups and forming tracks to ensure smooth unpacking of special proportion cartons.
Pain Point 4: Unstable air source pressure in the factory affecting forming effect
Solution: The equipment is preset with an air source adaptation range of 6kgf/cm². Meanwhile, a pressure stabilizing valve and air storage tank can be installed at the air inlet as optional configuration, maintaining stable unpacking actions even with fluctuating factory air source.
