Ring Type Wrapping Machine

1. Product Overview

Automatic Ring-Type Pallet Stretch Wrapping Machine

The HD SYSTEM Automatic Ring-Type Pallet Stretch Wrapping Machine is a high-speed automatic wrapping system designed for continuous pallet packaging lines.

The ring-type wrapping structure allows the stretch film carriage to rotate around the palletized load while the pallet remains stationary. This enables fast and stable wrapping without rotating the product itself.

The system is particularly suitable for high-speed production environments where consistent wrapping quality, short cycle time, and continuous automatic operation are required.

The machine can be integrated with pallet conveyors, top sheet applicators, centering systems, pallet positioning units, automatic film replacement systems, and other packaging automation equipment.

3. Machine Specifications

* Actual performance and specifications depend on pallet size, product characteristics, film specifications, wrapping pattern, and complete line configuration.

4. Ring Wrapping Principle

The Ring-Type Stretch Wrapping Machine wraps the palletized product while keeping the pallet stationary.

The wrapping ring rotates around the load and the film carriage moves vertically to cover the required wrapping height.

The wrapping process generally consists of:

1. Pallet enters the wrapping station.

2. Pallet position is detected.

3. Pallet is automatically positioned.

4. Product height and wrapping parameters are confirmed.

5. Stretch film is supplied to the film carriage.

6. Ring starts rotating around the load.

7. Film carriage moves vertically according to the selected wrapping recipe.

8. Film tension and pre-stretch are controlled during wrapping.

9. Top and bottom wrapping cycles are completed.

10. Film is automatically cut and secured.

11. Ring returns to the home position.

12. Wrapped pallet is transferred to the next process.

5. High-Speed Wrapping Performance

The ring wrapping structure is designed for high-speed pallet packaging applications.

A dual film carriage configuration can be applied to reduce the wrapping time while maintaining stable film coverage.

The system can be configured for a target capacity of:

Up to 60 pallets/hour

with a target cycle time of:

≤ 60 seconds/pallet

Actual production capacity depends on pallet dimensions, product height, wrapping turns, film characteristics, conveyor transfer time, and upstream/downstream equipment.

6. Dual Film Carriage System

The machine can be equipped with two independent film carriages.

The dual carriage configuration provides:

• Reduced wrapping cycle time

• Increased production capacity

• Simultaneous film application

• Improved wrapping efficiency

• Independent film tension control

• Independent film pre-stretch control

The film stretch ratio can be configured according to the selected film specification.

Typical selectable pre-stretch ratios include:

• 250%

• 300%

• 350%

7. Wrapping Parameters

The HMI allows the operator to configure and manage wrapping parameters.

Typical parameters include:

• Ring rotation speed

• Film carriage speed

• Film tension

• Film pre-stretch ratio

• Bottom wrapping turns

• Top wrapping turns

• Total wrapping turns

• Film overlap

• Wrapping height

• Reinforcement wrapping

• Wrapping start position

• Wrapping end position

Multiple recipes can be stored for different pallet and product sizes.

8. Automatic Film Replacement

An automatic film replacement system can be incorporated into the ring wrapper.

When the film roll is depleted, the system can automatically perform the programmed film replacement sequence, minimizing operator intervention and reducing production downtime.

The automatic film replacement function can include:

• Film end detection

• Empty roll detection

• New film roll positioning

• Automatic film attachment

• Film cutting

• Film tension recovery

• Automatic restart

9. Product Size Management

The system can manage different product sizes through recipe-based control.

Different product size groups can be assigned individual wrapping parameters, including:

• Product length

• Product width

• Product height

• Film stretch ratio

• Wrapping turns

• Film overlap

• Wrapping speed

Optional laser measurement sensors or additional photoelectric sensors can be installed when automatic product size detection is required.

10. Production Line Integration

The Ring-Type Stretch Wrapping Machine can be integrated into a complete automated pallet packaging line.

Typical Configuration

Infeed Conveyor → Top Sheet Applicator → Centering / Positioning Conveyor → Ring Wrapper → Outfeed Conveyor

Additional equipment can include:

• Automatic Palletizer

• Pallet Dispenser

• Top Sheet Applicator

• Centering Device

• Pallet Positioning System

• Automatic Film Replacement System

• Corner Protection Applicator

• Labeling System

• Pallet Warehouse

• AGV / AMR System

The main PLC can exchange pallet position, product size group, wrapping completion, alarm, and production status signals with the customer's automation system.

13. Advantages

High-Speed Automatic Wrapping

The ring-type wrapping mechanism is designed for high-speed operation and continuous pallet packaging.

Stationary Pallet

The pallet and load remain stationary while the wrapping ring rotates around the product, making the system suitable for loads that should not be rotated.

Dual Film Wrapping

The optional dual film carriage configuration can significantly improve wrapping throughput compared with a single film carriage system.

Consistent Wrapping Quality

Controlled film tension, pre-stretch ratio, wrapping speed, and wrapping cycles provide consistent packaging performance.

Flexible Product Management

Different product sizes and wrapping specifications can be managed using HMI recipes and automatic detection systems.

Complete Line Automation

The machine can be integrated with conveyors, top sheet systems, pallet positioning systems, automatic film replacement, warehouse systems, and factory automation systems.
