Article

This document details the proper installation procedure for the NexBot Robotics 841-009 Vibratory Parts Feeder (SKU: NXB-GEN-841-009). Following these steps ensures safe and efficient integration into your automated workcell.

Prerequisites

Before beginning the installation, ensure the following conditions are met.

Safety Precautions:

• All personnel involved must be qualified to perform mechanical and electrical work.
• Disconnect and lock-out/tag-out (LOTO) all power sources to the workcell before beginning installation.
• Always wear appropriate Personal Protective Equipment (PPE), including safety glasses and gloves.

Tools & Equipment:

• Torque wrench (rated for at least 100 Nm)
• Metric socket set
• Precision level or machinist's level
• Digital Multimeter (DMM)
• Wire strippers and crimpers
• Screwdriver set (flathead and Phillips)
• Lifting equipment rated for the weight of the feeder

Workstation Preparation:

• The mounting surface must be rigid, flat, and perfectly level to ensure proper feeder performance.
• Verify the surface can support the operational weight and vibrations of the feeder.
• Ensure the installation area meets the feeder's footprint requirements (600 mm x 600 mm) with adequate clearance for maintenance access.
• Confirm the availability of a suitable power source (110VAC or 220VAC) near the installation point.

Step-by-Step Instructions

Step 1: Unpacking and Inspection

1. Carefully unpack the NXB-GEN-841-009 feeder from its shipping container.
2. Inspect the unit for any signs of damage that may have occurred during transit. Check the stainless steel bowl for dents and the drive unit housing for cracks.
3. Verify that all components, including the feeder base, bowl, and any included controller or documentation, are present.
4. Report any damage or missing components to your NexBot Robotics representative immediately.

Step 2: Mechanical Mounting

1. Using appropriate lifting equipment, carefully position the feeder base onto the prepared mounting surface.
2. Align the mounting holes on the feeder's base with the corresponding holes on your workstation frame or stand.
3. Loosely install the required mounting hardware (typically four M12 bolts, not included).
4. Place a precision level across the top flange of the bowl. Adjust the position and use shims if necessary until the unit is perfectly level in both X and Y axes. A level installation is critical for consistent part feeding.
5. Once level, tighten the mounting bolts in a star pattern to a final torque of 80 Nm.

Step 3: Electrical Connection

> WARNING: Risk of electric shock. Ensure all power is disconnected and verified with a multimeter before opening the terminal box. All wiring must be performed by a qualified electrician and comply with local electrical codes.

1. Locate the electrical terminal box on the side of the feeder's electromagnetic drive unit.
2. Remove the cover plate.
3. Before connecting power, locate the voltage selection switch inside the unit. Set it to the correct voltage for your facility (110VAC or 220VAC).
4. Route your power supply cable through a suitable liquid-tight conduit fitting to maintain the unit's IP54 rating.
5. Connect the power supply wires to the appropriate terminals (L - Line, N - Neutral, G - Ground).
6. Connect any control wiring between the feeder's vibration controller and the robot controller's I/O module. This typically includes signals for Feeder On/Off and a Part Present sensor output. Refer to the electrical schematic for your specific robot model (e.g., NexBot C-10 or S-5 series) for I/O integration details.
7. Securely replace the terminal box cover.

Step 4: Initial Tuning

1. Ensure the bowl is empty before initial power-on.
2. With the workcell clear of personnel, re-engage the main power source.
3. Using the feeder's dedicated controller, set the vibration amplitude to its lowest setting.
4. Turn the feeder on. You should hear a low hum and feel a slight vibration.
5. Gradually increase the vibration amplitude until you observe a smooth, consistent flow of parts along the track. Avoid excessive vibration, which can cause parts to jump off the track or damage the feeder.
6. The goal is to find the lowest effective amplitude that provides the required feed rate for your application.

Verification

1. Functional Test: Load a small quantity of the actual production parts into the feeder bowl.
2. Observe Part Flow: Run the feeder and observe how the parts move up the track. Ensure they are being correctly oriented by the bowl's internal tooling.
3. Check Feed Rate: Time the output to ensure the feed rate meets the cycle time requirements of your robotic application.
4. Sensor Check: Verify that the part-present sensor at the end of the track is reliably detecting parts and sending the correct signal to the robot controller.
5. Long-Duration Test: Run the feeder for an extended period (e.g., 30 minutes) to check for consistency and ensure the drive unit does not overheat.
6. Once verified, the NXB-GEN-841-009 is ready for integration into your production sequence.
