Delivery Vehicle Detection with Indication in Warehouse
Suitable for outdoor environments – QT50U ultrasonic sensors are completely sealed and leakproof for outdoor use while LED indicators are available with washdown-rated models as well
Real-time alerts – Real-time monitoring with wireless products keeps deliveries moving efficiently
High Traffic at Loading Dock Doors Influences Efficiency
Loading docks are key access points inside a global electronics manufacturing company and can directly influence the general workflow of a warehouse. Inventory is frequently shipped in and out of docks and creates a very busy setting. Maintaining a steady flow of traffic at dock doors keeps processes efficient, productive, and reduces the number of shipping errors. An automatic system that alerts employees of vehicles waiting to be serviced works well for large facilities where employees are not always near the service doors.
Detection Challenges at Outdoor Dock Doors
Detecting vehicles at a loading dock can be difficult because of unpredictable weather and environmental changes. Sensors installed here will likely be exposed to the elements and need to withstand fluctuations in weather and ambient light.
Truck surfaces are made of a variety of materials and come in a wide range of colors. This can prove challenging for traditional sensors. A solution is needed that can reliably detect surfaces regardless of color, reflectivity, or texture. The range can also present some challenges for sensing because vehicles vary in size and distance away from the sensor.
Electronics manufacturing facilities are also loud environments where standard doorbells may go unnoticed. Indication lights may also be missed due to the prevalence of overhead and machine lighting throughout a warehouse setting.
Proximity Sensing with Wireless Indication Capabilities
Banner Engineering’s QT50U series ultrasonic sensor uses sound waves to detect a truck’s arrival. The ultrasonic waves bounce off the surface of the vehicle and back to the sensor, recognizing if a delivery vehicle is at the dock door for service. It can be taught a reliable background and therefore recognize when vehicles are present. The QT50U is paired with a DX80 wireless node to send an output to trigger an alarm to employees, informing them of vehicles that are waiting to be serviced.
The QT50U works well for outdoor loading docks because they are rugged and built to withstand harsh environments. They are made with completely sealed, shock-resistant housing. Chemical-resistant, Teflon-coated models are also available for purchase. The QT50U ultrasonic sensors are easy to set up with push-button and remote TEACH-mode programming.
TL70 tower lights with audible alarms were installed in the warehouse to alert employees of waiting trucks. The TL70 can be heard and seen throughout the warehouse floor to ensure that deliveries get tended to quickly. Delivery dock applications also have other opportunities to install bright LED indicator lights for unmistakable operator guidance. K50 touch buttons can be installed as doorbells and connected to K80L segmented indicators to show which dock is in use. Banner LED technology provides low-power and long-life lighting products for bright visibility in a wide variety of settings.
Loading docks can become chaotic if trucks and other deliveries are neglected for extended periods of time. Using Banner’s QT50U for vehicle detection creates optimum workflow and traffic management. These rugged ultrasonic sensors use sound waves to detect almost any surface, regardless of color, texture, and reflectivity. They can withstand outdoor environments without sacrificing sensing capabilities. With a sensing range up to 8 m, the QT50U can detect many different sized vehicles. A DX80 wireless node allows for indication and alerts to be broadcast throughout the warehouse floor with LED tower lights and indicators.
Features a completely sealed, shock-resistant housing that is ideal for tank level monitoring of liquids as well as solids.
Create point-to-multi point networks that distribute I/O over large areas. Input and output types include discrete (dry contact, PNP/NPN), analog (0 to 10 V dc, 0 to 20 mA), temperature (thermocouple and RTD), and pulse counter.
K50 Series touch buttons combine a large, bright indicator with solid-state, touch-activated switching capability, ideal for lean manufacturing and bin-picking operations.
Big, bright tower lights come preassembled or as modular segments for customized indication. Lights are gray when off to eliminate false indication.
