A Beginner’s Guide to Operating Granule Vertical Packing Machines

In the realm of packaging, vertical packing machines reign supreme for their efficiency and versatility in handling granule-based products. For those new to operating these machines, this beginner’s guide will provide a comprehensive overview of their functions and operation.

Machine Overview

Granule vertical packing machines are designed to automatically package free-flowing granules into preformed bags or pouches. They typically consist of a film unwinder, a forming tube, a filling system, a sealing unit, and a conveyor system.

Film Handling

The film unwinder plays a crucial role in supplying the packaging material to the machine. It holds a roll of film and controls its tension and speed to ensure proper bag formation. The forming tube, located after the film unwinder, shapes the film into a vertical tube, creating the bag’s side walls.

Filling System

The filling system accurately dispenses the granules into the formed bag. It can be either volumetric or auger-based. Volumetric fillers measure the volume of granules, while auger fillers use a rotating screw to convey the granules into the bag.

Sealing Unit

Once the bag is filled, the sealing unit secures it by applying heat and pressure. The most common sealing methods are hot-jaw sealing for plastic films and cold sealing for paper-based bags. The sealing unit ensures that the bag is airtight and tamper-evident.

Conveyor System

The conveyor system transports the filled and sealed bags out of the machine. It can be a simple conveyor belt or a more complex system with multiple belts and sensors to ensure smooth and efficient bag handling.

Operation Sequence

1. Power Up: Turn on the main power supply and initialize the machine.

2. Film Loading: Load the film roll onto the unwinder and adjust its tension.

3. Set Parameters: Configure the machine settings, such as bag size, fill volume, and sealing temperature.

4. Start Filling: Start the filling system to dispense granules into the formed bag.

5. Seal and Cut: The sealing unit seals the bag and cuts it to the desired length.

6. Discharge: The conveyor system discharges the filled and sealed bags from the machine.

Troubleshooting

Like any machine, granule vertical packing machines can experience occasional issues. Common problems include:

1. Bag Jamming: Ensure the film is properly tensioned and the forming tube is clean.

2. Granule Leakage: Check the sealing unit for proper alignment and temperature settings.

3. Incorrect Fill: Calibrate the filling system or inspect the measuring system.

4. Electrical Faults: Consult a qualified electrician to diagnose and repair electrical issues.

By understanding the operation and potential issues of granule vertical packing machines, beginners can effectively operate these machines and ensure efficient and reliable packaging.
