EXAMPLE APPLICATIONS

TO ILLUSTRATE THE WIDE-VARIETY OF APPLICATIONS SOLVED USING CONTRINEX SENSORS, WE HAVE POSTED A LARGE SELECTION OF EXAMPLE APPLICATIONS WHICH CAN BE SEEN BY CLICKING ON AN IMAGE. BELOW ARE A SELECTION OF SOME OF THESE APPLICATIONS:
A sensing range up to 1200 mm, adjustable via a teach button or via IO-Link, accommodates a wide range of machine geometries. Sensitivity parameters are stored on the sensor’s inbuilt memory and may be retrieved or updated remotely via IO-Link, eliminating the need for manual adjustment. These rugged miniature sensors meet the customer’s need for reliable operation with little or no manual intervention. The solution is highly cost-effective with minimal non- productive time; throughput is maintained at or above target levels.

CUSTOMER VALUES Safe detection of the thinnest transparent materials Maximum operating reserve owing to high absorption factor of UV light by transparent plastics Elimination of multiple switching on a single target Reliable operation without the need for manual intervention Very low sensitivity to dust, liquid droplets and splashes PRODUCT ADVANTAGES Remote sensitivity retrieval or update via IO-Link IO-Link serial-connection protocol enabled on PNP versions at no additional cost Pre-taught sensitivity parameters stored on inbuilt sensor memory Highly tolerant of contamination by dust, liquid droplets or splashes
During the automated packaging of fast-moving products, thermoformed transparent plastic tray bases are common. Contrinex’s small C23 transparent-object sensor with patented UV technology detects the presence of each set of transparent trays after it is formed, initiating a subsequent operation and, optionally, triggering a counting circuit. The Ecolab-certification of these sensors make them suitable for the packaging of food and medical products. CUSTOMER APPLICATION A manufacturer of packaging machines for the medical industry produces automated blister-packaging lines for pharmaceutical and surgical products. Medical blister-packs comprise a recessed, semi-rigid tray base, vacuum-formed in- line from a clear thermoplastic material and sealed with a metal or plastic film after the desired products are loaded. Typically, blister-packaging lines for surgical products operate in sterile conditions; minimal manual intervention is permitted, as contamination may enter the environment. If defective bases are identified and rejected after forming, the flow of tray bases to the loading station is not continuous. In this event, a sensor system must inhibit the loading cycle until a base is in position. Sensors must detect the presence of transparent tray bases swiftly and reliably, enabling the loading cycle to proceed with minimal delay as soon as a tray is present at the loading station. Standard photoelectric sensors, which use visible red- light sources, proved unreliable as they are unable to differentiate reliably between ‘tray present’ and ‘tray not present’ conditions. An alternative sensor is required which will detect the presence of a transparent plastic target under normal operating conditions
CUSTOMER SOLUTION Transparent-object sensors with ultraviolet LED-light sources from the Contrinex C23 product series are ideally suited to this application. These miniature cubic devices, mounted above product conveyors, detect the presence of transparent tray bases as they arrive at the loading station. Positioning sensors is simple thanks to a range of adjustable mounting brackets, and auto-collimated optics ensure there are no blind zones. Contrinex transparent-object sensors utilize a patented reflex operating principle with polarized ultraviolet light at 275 nm. At this wavelength, absorption of the polarized UV light by a range of commonly used plastics is maximized. Custom- designed UV reflectors, using high-tech plastic materials with excellent reflective properties in the ultraviolet range, provide a range of sizes and geometries that simplify installation. An industry-standard PNP normally open output ensures optimum flexibility. Additionally, IO-Link, a standardized point-to-point serial connection protocol for sensors and actuators, is enabled on PNP versions at no additional cost. An additional option is to have a second output to provide the stability alarm in the event of reduced sensitivity, flagging the need for preventative maintenance before any performance degradation occurs. The robust sensors which are only 20mm x 30mm x 10mm feature Ecolab-certified plastic housings. A sensing range up to 1200 mm, adjustable via a teach button or via IO-Link, accommodates a wide range of machine geometries. Sensitivity parameters are stored on the sensor’s inbuilt memory and may be retrieved or updated remotely via IO- Link, eliminating the need for manual adjustment. The robust sensors which are only 20mm x 30mm x 10mm feature Ecolab-certified plastic housings, are corrosion- resistant and impervious to water ingress and has the additional benefit of offering a range of low-cost stainless- steel mounting and protection bracketry.

CUSTOMER VALUES UV sensors ensure reliable detection of transparent, irregularly shaped plastic targets Elimination of multiple switching on a single target Wide operating range accommodates full range of machine geometries Simple one- or two-step teach procedure optimiSes initial set-up Sensitivity parameters are retrieved or updated remotely via IO-Link Stability alarm highlights reduced sensitivity for example for Preventative Maintenance PRODUCT ADVANTAGES Ultraviolet reflex photoelectric sensors for transparent object detection Very low sensitivity to target shape Robust, Ecolab approved sensors with IP67-rated small plastic housings
Thermoforming lines produce transparent plastic trays from continuous reels of material. Contrinex’s transparent-object sensors with patented UV technology are used to detect the presence of the transparent plastic sheet as it is unwound from the reel, ensuring the material is correctly tensioned as it enters the loading station. False detection is avoided, ensuring reliable operation with little or no downtime. CUSTOMER APPLICATION Thermoforming equipment is often used in the production of plastic packaging and is particularly suitable for the continuous production of blister-packs. The process involves the in-line vacuum-forming of clear thermoplastic material into semi-rigid blister-trays which, after insertion of the desired products, are sealed with film. Configurable thermoforming lines are ideal for the high-speed production of such blister-trays from continuous reel-stock material. Coupling a standalone reel-feeder to the loading station of a modular line is quick and simple. In operation, a set of drive rollers draws thermoplastic sheet from the stock reel, creating a continuous loop of material between the feeder and the loading station. Maintaining the size of the loop between defined limits ensures the material is correctly tensioned as it enters the loading station. Sensors detect the presence of the transparent material as the loop size varies, initiating or inhibiting operation of the feeder if the loop becomes too small or too large, respectively. Photoelectric sensors using visible-light sources are unreliable in such an application as they cannot reliably differentiate between ‘material present’ and ‘material not present’ under normal operating conditions.
CUSTOMER SOLUTION Contrinex C23 transparent-object reflex sensors with ultraviolet LED-light sources are ideally suited to this application. These miniature cubic devices, mounted between the reel feeder and the loading station, detect the presence of the transparent material loop as its size varies. Positioning the sensors and reflectors is simple using a range of adjustable mounting brackets, and auto-collimated optics which ensure there are no blind zones. Contrinex transparent-object sensors utilise a patented reflex operating principle with polarised ultraviolet light at 275 nm. At this wavelength, absorption of the polarised UV light by a range of commonly used plastics is maximised. Custom- designed UV reflectors, using high-tech plastic materials with excellent reflective properties in the ultraviolet range, are available in a range of sizes and geometries which simplify installation. An industry-standard PNP normally open output ensures optimum flexibility. Additionally, IO-Link, a standardized point-to-point serial connection protocol for sensors and actuators, is enabled on PNP versions at no additional cost. An additional option is to have a second output to provide the stability alarm in the event of reduced sensitivity, flagging the need for preventative maintenance before any performance degradation occurs. The robust sensors which are only 20mm x 30mm x 10mm feature Ecolab-certified plastic housings, are corrosion- resistant and impervious to water ingress and has the additional benefit of offering a range of low-cost stainless- steel mounting and protection bracketry.
The Contrinex TRU-C23 photoelectric sensor is ideally suited for the presence control of transparent objects. Its patented technology uses UV light. Since transparent materials like plastic or glass absorb large amounts of polarized UV light, it is very easy to set the threshold at which the sensor switches. This makes commissioning much easier. The shape or thickness of the target has no influence on detection. In addition, sensor performance is unaffected by dirt, water drops or aging. Multiple switching for the same object is eliminated. The sensor system comprises an LED that emits polarized UV light and a reflector made of special materials suitable for UV. Overall, the sensor’s operating range is around 1200 mm. Special optics with auto-collimation ensure reliable detection and no blind zone, even close to the sensor or through a small notch. For applications requiring the detection of thicker or larger transparent objects, the C23 Transparent Standard can be the ideal solution. It operates with polarized, red light and has a maximum operating range up to 5000 mm. This sensor provides a highly favourable price-performance ratio. Typical fields of application can be found in the food, pharmaceutical and packaging industries, for example when filling glass or plastic bottles, packing in plastic or when the detection of clear packaging film is required. The housing, which for both types measures only 30 x 20 x 10 mm, is compatible with the entire C23 series as well as comparable devices. The IO-Link interface also provides the important additional benefit of remote commissioning, diagnostics and parameterisation as standard and at no extra cost. Sensors are Ecolab tested and approved, rated to IP67 and reliably withstand common industrial cleaning processes.
