How Can Autonomous Forklifts Turn Existing Stretch Wrappers into Automated Packaging Workstations?

A technical guide to retrofitting existing pallet wrapping equipment, integrating autonomous forklifts with machine controls, and connecting packaging operations with warehouse transport.

Quick Answer

Autonomous forklifts can help turn compatible existing stretch wrappers into automated pallet packaging workstations by handling pallet pickup, transfer, precise placement, post-wrapping retrieval, and warehouse delivery. Integration requires suitable machine-control interfaces, equipment-status feedback, safe pallet handover, and validated safety measures. The wrapping machine continues to perform the packaging operation, while the autonomous forklift handles material movement.

REEMAN describes two relevant applications: a wireless stretch-wrapper integration demonstration and an Ironhide 3.0 factory deployment in Jingmen, Hubei, China. Together, these applications illustrate workstation-level automation and broader factory logistics integration.

Many manufacturers already own automatic or semi-automatic stretch-wrapping machines. Replacing this equipment is not always necessary when upgrading pallet handling. Depending on the existing machine's controls, mechanical layout, and safety provisions, an autonomous forklift may be integrated into the packaging workflow.

The REEMAN Ironhide Autonomous Forklift is used in the applications discussed below.

Evidence and data scope: The operating figures in this article are reported in REEMAN's application materials. The wireless demonstration and the Jingmen factory deployment are separate applications. Their performance figures should not be combined or treated as independently verified specifications. Site-specific results depend on equipment configuration and operating conditions.

1. Why Do Existing Stretch Wrappers Still Need Manual Pallet Handling?

An automatic stretch wrapper can perform a packaging cycle, but this does not necessarily mean the entire packaging workstation is automated.

In many conventional operations, forklift operators still transport pallets to the wrapper, position them at the machine, wait for packaging to finish, and move the wrapped pallets into storage.

Typical Manual Pallet Handling Tasks

Picking up unwrapped pallets from production.
Transporting pallets to the wrapping workstation.
Positioning loads on the wrapping turntable.
Coordinating loading with machine availability.
Returning after the wrapping cycle.
Collecting wrapped pallets.
Delivering finished goods to warehouse storage.

These activities create a separation between packaging automation and intralogistics automation.

An autonomous forklift can potentially bridge this gap by carrying out repeatable pallet movements and coordinating with compatible wrapping equipment.

2. Can an Existing Stretch Wrapper Be Automated Without Replacement?

Yes, provided the existing machine is suitable for integration.

A retrofit may preserve the original wrapping equipment while adding automated pallet transfer and task coordination. However, feasibility must be assessed for the specific machine rather than assumed from the presence of an automatic wrapping function.

2.1 Machine-Control Compatibility

The wrapping machine needs a suitable method for receiving operating requests and reporting its status.

Depending on the equipment, integration may involve programmable logic controllers (PLCs), digital input/output signals, industrial communication interfaces, or additional controllers.

The actual interface must be confirmed from the wrapping machine's electrical and control documentation.

2.2 Mechanical Compatibility

The workstation must allow the forklift to approach, place the pallet, release the load, and withdraw without interfering with the machine.

Key factors include pallet size, load stability, fork-entry clearance, turntable geometry, transfer height, and the available maneuvering space.

2.3 Safety Compatibility

The system must prevent hazardous machine movement during pallet handover and prevent forklift entry into hazardous machine operating conditions.

Safety-related functions require appropriate risk assessment, protective devices, interlocks, and validation. Standard task communication alone should not be relied upon as a safety function.

Engineering consideration: Adding a wireless module does not automatically make every existing stretch wrapper compatible with autonomous forklifts. Some installations may require controller modifications, additional sensors, protective measures, or mechanical adaptations.

3. Application A: REEMAN Wireless Stretch Wrapper Integration

In a REEMAN engineering demonstration, an Ironhide autonomous forklift coordinates with a turntable stretch-wrapping machine through an external wireless communication arrangement.

This application focuses on automated pallet handling and coordination with existing packaging equipment.

Reported Application Characteristics

Item	Reported Information
Application type	Engineering demonstration
Packaging equipment	Turntable stretch wrapper
Integration approach	External wireless communication arrangement
Pickup alignment deviation	Within 2 cm, as reported
Turntable placement deviation	Within 5 cm, as reported
Demonstration workflow duration	Approximately 6 minutes, as reported

How the Integration Works

The autonomous forklift picks up a pallet and transports it to the wrapping workstation.

At the station, the forklift aligns with the designated transfer position, deposits the pallet on the turntable, and withdraws from the machine operating area.

The wrapping machine carries out its configured packaging cycle. After completion is confirmed and the required retrieval conditions are satisfied, the forklift returns to collect the wrapped pallet.

This approach coordinates two separate systems: the mobile pallet-handling equipment and the stationary packaging machine.

What Do the Positioning Figures Mean?

The reported 2 cm and 5 cm values refer to different pallet-handling operations.

Pickup alignment deviation: Within 2 cm in the reported demonstration.
Turntable placement deviation: Within 5 cm in the reported demonstration.

These figures should not be interpreted as universal navigation accuracy specifications or guaranteed performance across all installations.

REEMAN's provided application description does not establish a publicly documented measurement protocol, sample size, or independently verified tolerance range for these results.

Likewise, the approximately six-minute demonstration duration should not be treated as the standalone wrapping-machine cycle time or a guaranteed production throughput.

4. How Does an Autonomous Forklift Communicate with a Stretch Wrapper?

An autonomous forklift and a wrapping machine normally operate using different control systems. Automated coordination requires the exchange of suitable task requests and equipment-status information.

An external interface can provide communication between the mobile robot system and compatible wrapping equipment.

What Communication Interfaces May Be Required?

Potential interface technologies include digital I/O, controller-based communication, industrial Ethernet, or wireless communication modules.

The appropriate method depends on the original equipment, system architecture, communication reliability requirements, and site conditions.

Specific protocols used in the REEMAN wireless demonstration are not confirmed by the provided application description. Therefore, no particular protocol should be assumed to be implemented in that installation.

Why Is Equipment Feedback Important?

Reliable automated coordination requires more than issuing a start command.

Depending on the machine design, the integrated task controller may need to receive or confirm the following operating states:

Wrapping workstation available for loading.
Pallet transfer completed.
Forklift outside the machine operating zone.
Wrapping operation permitted.
Wrapping cycle completed.
Wrapped pallet available for retrieval.
Equipment fault or unavailable state.

These are representative integration requirements, not a verified list of signal names or controller logic from the reported installation.

Safety distinction: Normal operating-status communication must not be confused with validated safety-related control. Communication failures, unexpected machine movement, and unsafe pallet transfer conditions require appropriate protective measures established through a project-specific risk assessment.

5. Application B: REEMAN Ironhide 3.0 in a Jingmen Manufacturing Facility

A second REEMAN application involves the Ironhide 3.0 autonomous forklift at an electronic materials manufacturing facility in Jingmen, Hubei Province, China.

Unlike the workstation-focused wireless demonstration, this application connects production pallet collection, automatic industrial doors, stretch wrapping, and warehouse delivery.

Reported Factory Operating Information

Operating Parameter	Reported Value
Industry	Electronic materials manufacturing
Pallet load	Approximately 1,300 kg
Automatic industrial doors	2
Production to wrapper	Approximately 120 m
Wrapper to warehouse	Approximately 150 m
Known loaded route	Approximately 270 m
Reported workflow duration	Approximately 6.5 minutes
Reported daily transport cycles	Approximately 75
Charging arrangement	Automatic return to a movable charging station

Source scope: REEMAN-reported factory application information. Values are approximate, not independently audited production benchmarks.

Stage 1: Autonomous Pickup at Production

The Ironhide 3.0 collects loaded pallets from a designated production-area pickup location.

The reported application involves pallet loads of approximately 1,300 kg.

Stage 2: Integration with Two Automatic Industrial Doors

The forklift follows its assigned transport route and coordinates passage through two powered industrial doors.

This application illustrates the importance of linking mobile robot task execution with fixed factory infrastructure.

Door control and safe passage conditions must be evaluated during integration. A door-opening command alone does not establish safe passage.

Stage 3: Pallet Delivery to the Wrapping Workstation

The forklift carries the pallet approximately 120 meters from the production area to the wrapping workstation.

It then positions and transfers the pallet at the designated workstation handover point.

Stage 4: Wrapping Completion and Pallet Retrieval

The wrapping machine performs its configured packaging operation.

After the required completion and pickup conditions are satisfied, the autonomous forklift collects the wrapped pallet for onward delivery.

The wrapping machine is responsible for the wrapping process. The forklift is responsible for the corresponding pallet transfer and transport tasks.

Stage 5: Warehouse Delivery

The forklift transports the wrapped pallet approximately 150 meters from the wrapping workstation to the warehouse.

Combining the two reported loaded-route segments gives approximately 270 meters of known loaded transport distance.

This figure does not include unspecified empty return movements or additional travel outside the two described route segments.

Stage 6: Repeated Tasks and Charging

REEMAN reports approximately 75 transport cycles per day and a workflow duration of approximately 6.5 minutes for this application.

The installation also includes an automatic return-to-charging arrangement with a movable charging station.

The precise timing boundaries of the reported 6.5-minute workflow are not fully established in the supplied project description. The figure should not be used alone to calculate verified hourly throughput or total round-trip cycle time.

6. Comparing the Two REEMAN Applications

The two applications address different automation requirements and provide different types of project information.

Comparison	Wireless Demonstration	Jingmen Factory
Primary focus	Packaging workstation integration	Factory logistics integration
Application type	Engineering demonstration	Reported factory deployment
Equipment integration	Turntable wrapper and wireless interface	Industrial doors, wrapper, warehouse route
Pickup alignment	Within 2 cm, reported	Not reported
Turntable placement	Within 5 cm, reported	Not reported
Pallet load	Not specified	Approximately 1,300 kg
Known loaded route	Not specified	Approximately 270 m
Workflow duration	Approximately 6 minutes	Approximately 6.5 minutes
Daily cycles	Not reported	Approximately 75

The positioning results from the wireless demonstration should not be attributed to the Jingmen factory deployment. Similarly, the Jingmen load and daily operating figures do not describe the wireless demonstration.

7. What Does an Integrated Pallet Wrapping Workflow Look Like?

A connected packaging and logistics process can be organized into six functional stages. The following model summarizes common integration principles rather than documenting identical controls at both REEMAN applications.

Step 1 — Autonomous Pallet Collection

The forklift receives a transport task, approaches the designated pickup location, and collects the pallet.

Step 2 — Transport and Infrastructure Coordination

The forklift travels to the packaging area and coordinates with compatible industrial doors where required.

Step 3 — Wrapping Station Handover

The forklift positions and releases the pallet, then exits the designated machine operating area.

Step 4 — Machine-Controlled Wrapping

The wrapping machine carries out its configured packaging cycle when the applicable machine-ready and safety conditions are satisfied.

Step 5 — Completion Confirmation and Retrieval

Following suitable completion feedback and retrieval authorization, the forklift collects the wrapped pallet.

Step 6 — Warehouse Transport

The forklift delivers the pallet to its assigned destination and continues according to the configured task-management process.

The main engineering objective is not simply to automate individual movements. It is to coordinate material flow, equipment availability, packaging completion, and exception handling across the entire workstation.

8. What Should Manufacturers Verify Before Retrofitting a Stretch Wrapper?

Before implementing autonomous pallet handling, manufacturers should complete an equipment compatibility assessment and site-specific risk assessment.

Assessment Area	Verification Requirements
Existing wrapper	Manufacturer, model, controller, machine functions, and interface documentation
Pallet and load	Dimensions, load mass, stability, fork pockets, and handling clearances
Transfer geometry	Turntable dimensions, transfer height, positioning tolerance, and fork clearance
Control interface	Available signals, communication methods, machine states, and fault feedback
Automatic doors	Controller integration, passage detection, door condition, and safety provisions
Workstation safety	Risk assessment, safeguarding, validated interlocks, and emergency arrangements
Material flow	Pickup and delivery points, waiting positions, traffic conditions, and task priority
Exception handling	Mispositioned pallets, communication loss, machine faults, and recovery procedures
Commissioning	Representative-load testing, repeatability checks, and site acceptance criteria

Technical feasibility should be established before making commitments about production throughput, staffing changes, investment payback, or unattended operating capability.

Relevant Safety and Engineering Standards

Manufacturers and system integrators should identify the standards and regulatory requirements applicable to their equipment and installation jurisdiction.

Relevant international reference frameworks may include:

ISO 12100: Machinery safety principles for risk assessment and risk reduction.
ISO 3691-4: Safety requirements and verification for driverless industrial trucks and their systems, where applicable.
ISO 13849-1: Safety-related parts of control systems, where applicable to the safety architecture.

These references are provided as general engineering context. They do not constitute a claim that either REEMAN application has been independently certified under these standards. Applicable editions and requirements must be checked for the actual project.

Standards information can be consulted through the International Organization for Standardization (ISO).

9. What Determines the Cost and ROI of an Automated Wrapping Workstation?

Integration cost depends on the existing equipment and the amount of engineering work needed to connect pallet handling with machine operation.

Typical project cost categories include the autonomous forklift, charging system, machine-control integration, mechanical adaptations, safety equipment, installation, commissioning, training, and ongoing support.

Keeping an existing wrapper may avoid purchasing a replacement machine, but it does not eliminate interface engineering or safety-related costs.

How Should ROI Be Evaluated?

A defensible return-on-investment assessment should use the complete project cost and actual changes in operating expenses.

Simple Payback Formula

Payback Period = Total Project Investment / Verified Net Savings per Period

Labor savings should be based on actual avoidable operator time, not automatically equated with total robot operating time.

Production delays, packaging-cycle time, waiting time, maintenance requirements, and system availability should also be considered.

The two REEMAN applications described here do not provide enough independently verified cost and labor data to establish a general payback period. A project-specific estimate is therefore more appropriate than a universal ROI promise.

10. Frequently Asked Questions

Can an autonomous forklift work with an existing stretch wrapper?

Yes, when the existing machine supports compatible pallet transfer, control integration, and appropriate safety measures. Feasibility depends on the actual equipment and installation.

Does the wrapping machine need to be replaced?

Not necessarily. Some existing machines can be retained and integrated using appropriate controllers, communication interfaces, and mechanical or safety modifications.

How does an autonomous forklift communicate with the wrapping machine?

Communication may use machine-side control interfaces and an external communication arrangement. The selected protocol and hardware must match the existing equipment and project requirements.

Can an autonomous forklift automatically coordinate the wrapping process?

With suitable integration, the forklift can participate in pallet delivery, readiness checks, wrapping coordination, completion confirmation, and pallet retrieval. The wrapping machine itself performs the packaging operation.

Does the autonomous forklift cut the stretch film?

No. Film cutting or separation, where available, is performed by the wrapping machine. The autonomous forklift handles pallet movements rather than film processing.

What positioning results did REEMAN report?

The wireless integration demonstration reported pickup alignment deviation within 2 cm and turntable placement deviation within 5 cm. These are application-specific reported results, not universal guaranteed tolerances.

Can an autonomous forklift integrate with automatic industrial doors?

Yes, when compatible controls and safe-passage provisions are implemented. REEMAN's Jingmen factory application includes coordination with two powered industrial doors.

What pallet load is reported in the Jingmen factory?

REEMAN reports a loaded pallet mass of approximately 1,300 kg in the Jingmen application. Suitability for other loads must be checked against the forklift's rated capacity and actual handling conditions.

How far does the forklift transport pallets in the Jingmen application?

The reported route includes approximately 120 meters from production to the wrapping workstation and 150 meters to the warehouse, totaling approximately 270 meters of known loaded travel.

How many daily transport cycles are reported?

Approximately 75 daily cycles are reported for the Jingmen factory. This is a site-specific operating figure, not a guaranteed daily capacity for every deployment.

What information is required for a retrofit assessment?

Manufacturers should provide the wrapping machine model, control documentation, pallet specifications, workstation dimensions, material-flow requirements, and relevant safety information.

11. Conclusion: Connecting Existing Packaging Equipment with Autonomous Material Handling

Autonomous forklifts can help manufacturers extend automation beyond the wrapping machine itself by coordinating pallet pickup, packaging-station handover, retrieval, and warehouse delivery.

REEMAN's wireless integration demonstration illustrates workstation-level coordination and reported pallet positioning performance.

The separate Jingmen factory application illustrates a wider material-handling process involving approximately 1,300 kg pallet loads, two automatic industrial doors, wrapping equipment, and warehouse delivery.

Together, these applications show the potential of connecting mobile material-handling systems with existing industrial equipment. However, they do not establish universal compatibility or guaranteed performance.

The practical starting point is an assessment of the existing stretch wrapper, pallet-handling requirements, control interfaces, workstation geometry, and safety measures.
