Carton Lifter for Carton Sealing Machine Integration

Carton Lifter for Carton Sealing Machine Integration

A carton lifter is used when cartons need to be lowered for easier manual packing and then lifted to the infeed height of a carton sealing machine.

In packaging lines, cartons may come from a carton unpacking machine, manual packing station, or low-level roller conveyor. The discharge height of the carton unpacking machine is about 600 mm from the floor. For normal cartons, this height may be acceptable. However, when the carton is too tall, the top opening becomes higher than a comfortable manual packing height.

In this situation, operators may need to raise their arms too high when placing products into the carton. This can reduce packing efficiency and make daily operation less comfortable.

Fangshiheng’s carton lifter is designed to solve this handling problem. After the carton comes from the carton unpacking machine, the lifter can lower the carton to a more suitable manual packing height. After packing is completed, the cylinder lifting platform raises the carton back to the carton sealing machine infeed height and transfers it forward through powered rollers.

Product Overview

This carton lifter is designed for packaging lines that need height adjustment between carton unpacking, manual packing, and carton sealing.

The machine is a non-standard pneumatic lift-and-transfer conveyor. It connects carton unpacking, manual packing, height adjustment, and carton sealing in one practical workflow.

The equipment can work as part of an automatic packaging line, or it can be used independently according to the factory layout.

The system supports foot-pedal control, powered roller conveying, signal connection with upstream and downstream equipment, and safety protection around the operator position.

Why Carton Height Adjustment Is Needed

Carton height is an important detail in manual packing.

When the carton exits the carton unpacking machine at about 600 mm from the floor, the carton bottom is already at a fixed conveyor height. If the carton itself is tall, the opening of the carton may be too high for comfortable manual loading.

This creates several production issues:

• Operators need to lift products higher during packing.
• Manual packing becomes less comfortable for tall cartons.
• Packing speed may become unstable during long shifts.
• Tall cartons may be harder to control when products are loaded.
• The line may need extra height adjustment before carton sealing.

The purpose of the carton lifter is to lower the carton for manual packing, then lift it back to the correct height for sealing.

How the Carton Lifter Works

The carton first comes from the carton unpacking machine or front conveyor.

After the carton reaches the lifter, the lifting platform can move down to create a more suitable manual packing position. The operator can then place products into the carton at a more reasonable height.

When packing is finished, the operator steps on the foot pedal to start the lifting process.

The cylinder lifts the platform to the same height as the carton sealing machine infeed rollers. When the platform reaches the upper position, the powered rollers start and transfer the carton into the carton sealing machine.

After the carton leaves the lifting platform, the discharge sensor confirms that the carton has moved out. The cylinder then returns automatically and waits for the next carton.

If the carton sealing machine is blocked, it can send a signal to the carton lifter. The lifter then pauses carton feeding until the blockage is cleared.

Designed for Packaging Line Connection

This carton lifter is suitable for production lines where carton height adjustment is needed between carton unpacking, manual packing, and carton sealing.

It can connect with a carton unpacking machine, carton sealing machine, roller conveyor, or other packaging-line equipment. The machine can also exchange signals with upstream and downstream equipment to support automatic start, stop, pause, and recovery logic.

This helps reduce uncomfortable manual packing height and makes carton transfer more stable before sealing.

Safety Design and Operation

Safety is important for lifting and transfer equipment.

The carton lifter includes an operator-side guard plate and protective fence. During operation, operators should not place hands or tools under the lifting platform. Maintenance should only be carried out after power is cut off, air is shut off, and pressure is released.

Before production, the platform height should be checked against the carton sealing machine infeed height. After the platform rises, the roller height should be level with the sealing machine infeed rollers.

The height difference should not be more than 2-3 mm. If the height difference is too large, the carton may jam when entering the carton sealing machine.

What to Check Before Choosing a Carton Lifter

Before selecting a carton lifter, buyers should confirm the real production conditions.

Important points include:

• Carton length, width, and height
• Carton weight
• Carton bottom condition
• Carton unpacking machine discharge height
• Manual packing height requirement
• Carton sealing machine infeed height
• Required table height adjustment range
• Whether the machine connects with a carton unpacking machine
• Whether signal connection with the carton sealing machine is required
• Operator loading position
• Workshop layout and line direction
• Safety fence and guard requirements
• Whether the machine should work independently or online

The final design should match the packaging process and floor layout. For non-standard carton handling projects, sample cartons and layout drawings are recommended before final confirmation.

Fangshiheng Solution

Fangshiheng provides packaging automation equipment and custom production-line modules for carton handling, carton forming, carton unpacking, carton sealing, cork packaging, and related industrial automation applications.

For carton lifter and sealing-machine integration projects, Fangshiheng can review the customer’s carton size, carton height, carton unpacking machine discharge height, manual packing position, sealing machine height, and line layout before recommending the equipment configuration.

The carton lifter can be used as a standalone lifting conveyor or connected with a carton unpacking machine, carton sealing machine, and powered roller conveyor system.

For production lines that require more automation, Fangshiheng can also review whether carton forming, carton sealing, conveying, packaging, and downstream transfer should be connected into one complete workflow.

Contact Fangshiheng

If your packaging line needs to lower tall cartons for manual packing and then lift them to the carton sealing machine height, Fangshiheng can help evaluate a suitable carton lifter solution.
