Width Measurement of Profiles with Glass Fiber Optic Light Curtains and Fiber-Optic Amplifiers
Width Measurement of Profiles with Glass Fiber Optic Light Curtains and Fiber-Optic Amplifiers
In the production of metal profiles, the presence and dimensions of the objects must be detected before a clamping device secures them in place. Profiles can be black, white, chrome, glossy or matt. Glass fiber optic light curtains based on the transmitter-receiver principle are used in confined spaces, together with a universal reflex sensor. The optical fibers are arranged in a single line to create a light band. The width is measured, the linear signal is output proportional to the glass fiber cover and the correct position is determined.

Detection of the Foil End via Contrast Sensors
Detection of the Foil End via Contrast Sensors
In the pharmaceutical industry, pills and tablets are packaged in blister packs to protect them from environmental influences, atmospheric oxygen or moisture. The packaging consists of foils that are unwound from the rolls during the production process. The end of the foil is marked with a marking adhesive strip. To ensure a continuous flow of material, contrast sensors detect this marking and can thus initiate a roll change. Thanks to the integrated jump detection, markings of different colors on different materials are reliably detected.

Slack Monitoring on Sheet Metal Belts with Ultrasonic Distance Sensor
Slack Monitoring on Sheet Metal Belts with Ultrasonic Distance Sensor
Continuous material supply must be ensured in punching machines. As a material buffer, the supplied metal sheets are guided through the system in the form of a hanging loop. This compensates for the time delay between replenishment and the production processes. To monitor this process, an ultrasonic distance sensor is installed above the loop. It checks whether the sag falls below the minimum value or touches the ground. Ultrasonic measurement is not affected by even very shiny plates and dirt such as oil mist or dust.

End Position Check of Panels in Buffer Storage with Ultrasonic Sensors
End Position Check of Panels in Buffer Storage with Ultrasonic Sensors
In the furniture industry, wood or plastic is processed in panels. Before processes such as sawing, they are temporarily stored in an automated buffer storage facility. Ultrasonic sensors are installed between the narrow conveyor rollers to detect the presence and end positions of the panels in the storage racks. In a compact 1K housing, the sensor detects objects precisely from close proximity even in dusty environments and with irregular surfaces, thus preventing multiple storage of panels. The sensors can be parameterized and process data read out via IO-Link before installation.

Production Monitoring of Parquet Tongues and Grooves via Laser Distance Sensor Triangulation with Analog Output
Production Monitoring of Parquet Tongues and Grooves via Laser Distance Sensor Triangulation with Analog Output
When manufacturing parquet flooring with tongues, it is important to ensure that the tongue is securely inserted into the groove in the parquet once pressed in. This is precisely monitored via laser distance sensors triangulation. Ideal for the wood industry: The sensors also work reliably in the event of flying chips and soiling. Since different parquet heights are produced on a single system, the respective distance to the background is detected via an analog output on the sensor. The sensors measure all relevant heights with their analog output: the distance to the conveyor belt, to the spring and to parquet.

Monitoring Empty Trays at the Airport with Laser Distance Sensor Time-of-Flight
Monitoring Empty Trays at the Airport with Laser Distance Sensor Time-of-Flight
After being handed in at the airport luggage check-in counter, suitcases and bags are placed in plastic trays for further transport and transported via conveyor technology. This makes handling and identification of the objects easier. Before the suitcases are placed in the containers, it is important to ensure that the trays are properly emptied. To do this, a robot gripper turns the tray over. The laser distance sensor time-of-flight installed above it measures the distance to the underside of the objects. If the distance to the bottom of the tray is within the tolerance, the tray is released for refilling. Related applications can be found here.

2D Code
A 2D code, also known as a two-dimensional code, consists of a pattern of dark and light elements (bars, rectangles and squares with corresponding spaces in between) which are arranged in a 2D fashion. 2D codes have a more complex layout than 1D codes, and the technology required for acquiring and deciphering them is more complex as well as the scanner must always read the entire pattern depicted by the barcode in order to acquire and decipher 2D codes, and not just a horizontal line as is the case with 1D Codes. Two-dimensional codes contain more diverse information than one-dimensional codes, for example information for the identification of products, texts such as addresses, and delivery note numbers. In general, we differentiate within the 2D codes between the stacked codes (stacked code) and the matrix codes (DataMatrix code).
