Application Notes
-
-
Shrink Sleeve Labeling at High Speeds
A leading manufacturer of labeling equipment offers high-speed shrink sleeve label applicators designed to process 800 bottles per minute. To maximize the machine’s performance potential, the company wanted to install sensors capable of consistent detection and output for high-speed bottling.
-
Box Sealer Status Indication
A solution was needed to better indicate a variety of complex statuses coming from a labeling machine. Banner's CL50 Pro column lights are an effective way to provide at-a-glance status indication.
-
Detecting Items On an AC-Powered Conveyor
WORLD-BEAM QS18 Universal Voltage sensors can be connected to either AC or DC power, allowing them to operate in large conveyor applications already using AC power without requiring a separate power supply. The robust, compact housing and multiple mounting options add to the versatility of WORLD-BEAM QS18 Universal Voltage sensors.
-
Carton Trigger For Date/Lot Code Printing
With a narrow beam that projects a small bright spot, the QS18LLP laser, polarized, retro-reflective sensors provide precise position control when triggering various devices. In this application, the QS18LLP is able to correctly detect the glossy carton as it travels down the conveyor—without proxing—and trigger the ink jet printer to print the date/lot code on the carton. The second sensor triggers the P4 OMNI to inspect the date/lot code and verify it is legible and correct.
-
Inspecting for Missing Chocolates on a Packaging Line
Banner sensors are positioned above a conveyor inspecting each passing box for missing chocolates. When a passing box breaks the trigger beam created by a pair of Q12 opposed-mode sensors, an array of QS18AF sensors mounted above the box inspect each location for missing chocolates. When a box containing the wrong amount of chocolates is detected, an output signal is relayed to a main controller at the packaging line warning of the failed condition.
-
Counting Food Cartons for Correct Packaging
Banner’s WORLD-BEAM QS18LP laser sensor accurately inspects every carton that passes on the conveyor, ensuring the robot is triggered to load cartons into the package. With a visible laser sensing beam, the QS18LP provides precise position control, which is ideal to ensure accurate counting of cartons at a close range. The rugged QS18LP is also ideal for confined spaces and is easily set up along a conveyor for accurate sensing. With highly bright LEDs, operating status is visible from 360⁰.

Parts Inspection on a Feeder Bowl Rail
In this illustration, precision machined bolts have just come out of the feeder bowl and are moving down the feeder bowl rail, conveying to the next automated step. As they move down the rail, a WORLD-BEAM QS18 detects the bolt and sends a triggering signal to an inspection sensor, the iVu Image Sensor. The iVu is configured to detect a flaw in the flange, irregular shape of the bolt head, or other flaws that might be present.
-
Part-in-Place Verification
The WORLD-BEAM QS18 adjustable field background suppression sensor is an excellent choice for this part-in-place application, requiring a three-inch scanning distance. With the combination of high-gain characteristics, sharp adjustable cutoff and a forgiving visible red light beam this sensor ensures longevity in this harsh environment.

Detecting PET Bottles to Regulate Product Flow
Sensor solutions to detect translucent bottles in a range of shapes, sizes, colors and contours in a high-speed air conveyance system, identifying gaps.
-
Counting Syringes Using Background Suppression
As syringes pass on a conveyor, a WORLD-BEAM QS18 with background suppression detects the individual barrels, passing the information to a counting device.
-
Clear and Reflective Targets
Detecting clear and reflective objects are some of the most challenging sensor applications. Light can burn through a target or be reflected away erratically, making accurate detection difficult.
