Procedure: Replacing, Relocating, or Bypassing the Pallet Sensor on the Robotiq Palletizing Solution AX10

Introduction:

This article explains how to replace, relocate, or bypass the pallet sensor on the Robotiq Palletizing Solution. These adjustments may be necessary when pallet overhangs interfere with detection, or when pallets are delivered using AGVs((Automated Guided Vehicle) that alter their height relative to the standard sensor setup.

Common Scenarios

• Overhanging pallets: If the pallet overhangs on the front, sides, or all around, the sensor may be unable to detect it properly.

• AGV integration: When pallets are placed by an AGV, they may sit higher than expected, putting them outside the detection range.

Instructions Overview

The instructions include step-by-step procedures for physical installation. Additionally, guidelines for documentation, safety precautions, testing, and validation are provided to ensure the successful implementation of modified pallet sensor configurations. Consult our coaches (support@robotiq.com) for further information.

Note: These instructions serve as a general guide. Always refer to the specific documentation and guidelines for your Robotiq Palletizing Solution model to ensure compatibility and adherence to safety protocols.

By following these instructions, you can modify the pallet sensor configuration to accommodate overhangs or integrate the solution with AGVs, enabling efficient pallet detection and improving the overall performance of the Robotiq Palletizing Solution.

Before performing any modifications, ensure the Robotiq Palletizing Solution is powered off and disconnected from its power source. Familiarize yourself with the system's components and safety precautions by reviewing the provided documentation for your specific model.

Bypassing the Sensor

If only one sensor is obstructed due to a partial overhang (front or side), you can bypass it.

Steps:

1. 1. Identify the obstructed sensor.

   2. Disconnect its cable from the I/O.

   3. Connect a bypass wire at the I/O to simulate the sensor's signal.

   4. Confirm that the system receives the expected signal during operation.

Replacing with a Proximity Sensor

For cases where overhangs are present on all sides or more precise detection is needed, replace the existing sensor with a proximity sensor.

Steps:

1. Remove the original sensor and bracket.

2. Mount the proximity sensor in a position that avoids obstruction.

3. Route the new cable cleanly to the control cabinet.

4. Update the wiring at the I/O accordingly

5. Test detection with standard pallet placement.

Relocating the Sensor for AGV Applications

When using AGVs, the pallet height may differ from standard. Sensor placement should match the AGV’s delivery height.

Steps:

1. Determine the average height of AGV-delivered pallets.

2. Mount the proximity sensor at that elevation on a suitable bracket.

3. Route wiring and secure the sensor.

4. Connect the sensor to the same I/O point as the original.

5. Validate detection using several pallet types and delivery positions.

Safety and Documentation

• Always power down the robot and control box before modifying wiring.

• Clearly document all changes:

  • Sensor model and location

  • Wiring modifications

  • Updated schematics (if applicable)

 Final Testing

• Power the system back on.

• Run a test cycle with a variety of pallet types.

• Observe whether the sensor reliably detects pallet presence.

• Adjust placement or settings if needed.

Conclusion Replacing, relocating, or bypassing the pallet sensor ensures continued reliability in scenarios where the standard configuration is no longer effective. Proper documentation and testing are essential to maintain system safety and performance.
