Installation Guide for Metal Detector
The installation of metal detectors is not only a physical process of fixing the equipment on the production line, but also a system engineering involving environmental assessment, mechanical integration, and electrical connection. Please be sure to follow the following steps and strictly adhere to the specific regulations in the equipment manual.
1、 Preparation work before installation
safety first:
Ensure that the installation area is completely powered off (equipment power supply and upstream and downstream associated equipment power supply).
Clean the installation area to ensure there are no debris or water stains.
Environmental assessment and location selection (crucial!):
Stay away from metal interference sources: The installation location must be away from large moving metal objects such as forklifts, metal doors and windows, large motors, frequency converters, etc. It is recommended to keep a distance of at least 1.5 meters.
Avoid electromagnetic interference: Keep away from high-power electrical equipment such as welding machines, variable frequency drives, and radio transmitters.
Ground stability: Choose the location with the least vibration, as excessive vibration can cause false alarms.
Adequate space: Ensure that there is enough space in front and behind the device to facilitate:
Connect the conveyor belt.
Perform maintenance and cleaning.
Set up a product collection box after removing the device.
Check equipment and accessories:
Check if the equipment model and caliber match the product size.
Check if all accessories are complete, such as brackets, screws, tool kits, calibration blocks, etc.
2、 Mechanical installation steps
Step 1: Install the bracket and main body
According to the height of the production line, use the provided bracket to firmly fix the main body of the metal detector on the ground or bracket.
Use a spirit level to ensure that the equipment is completely level. Any tilt may cause the product to roll or slide within the detection area, resulting in false alarms.
Step 2: Integrated Conveyor System (if applicable)
If the metal detector comes with a conveyor belt, it needs to be accurately aligned with the front and rear conveyor belts on the production line.
Ensure that the centerline of the conveyor belt is aligned with the centerline of the inspection hole.
Adjust the equipment legs to ensure that the height of the conveyor belt is level with the height of the conveyor belts on the front and rear production lines, ensuring that the products pass smoothly and without bumps.
Step 3: Install the removal device
Install it at the outlet end of the detector according to the removal method you have chosen (such as push rod, flip plate, air blowing, etc.).
Ensure a secure installation and adjust the force and timing of the removal action to effectively remove products containing metal impurities without excessive force causing damage or splashing.
Connect the power source of the removal device (such as compressed air for air blowing).
3、 Electrical installation and connection
Power connection:
Connect the correct power source (AC 220V/380V, etc.) according to the instructions.
Ensuring good grounding of the equipment is the foundation for ensuring detection accuracy and equipment safety.
Signal connection:
Connecting with upstream equipment: It is usually necessary to receive "synchronization signals" or "rejection delay signals" from upstream equipment (such as filling machines, packaging machines) to ensure accurate timing of detection and rejection.
Connect to the removal device: Connect the control output signal line of the metal detector to the control unit of the removal device.
Connecting with downstream devices: It can output signals to downstream devices (such as labeling machines, robots) to notify them that defective products have been removed.
Shielding and wiring:
All signal lines should use shielded cables and the shielding layer should be grounded at one end to prevent external electromagnetic interference.
4、 Debugging and calibration after installation
This is the most technical part of the installation process, which directly determines the detection effect.
