A Japanese manufacturer of canned products uses inductive sensors with analogue outputs in the packaging department to check that closed cartons have the required number of cans inside. The sensor’s analogue output enables it to process different can sizes and materials in a final pre-shipment quality check for a range of product types. CUSTOMER APPLICATION Canned products are fragile, easily crushed or pierced. They are protected during delivery by being tightly packed into sturdy cardboard boxes. However, this packaging process may itself damage the cans if a fault occurs and, once the box is closed, there is no longer any possibility of a final visual check. To eliminate product faults that may have occurred during upstream processes, the customer seeks a means of verifying product quality inside the box. The solution chosen must be able to deal with all canned products in the manufacturer’s delivery range, comprising cans in different sizes and materials. This is not possible with an ordinary on-off switching sensor output. The verification process must also be integrated into a fast-moving automated packaging and pre- shipment line, accepting or rejecting each carton instantly. Customer Solution Analogue inductive sensors from the 509 Series are ideal for this application. Their Condist® oscillator technology ensures excellent environmental stability – especially to temperature – and so allows operating distances up to 3 times the standard (in this case 40 mm). The extra distance enables them to obtain a good signal not only through multiple layers of cardboard, but also from different conductive metals at varying distances, depending on can type. The customer has mounted inductive analogue sensors on two conveyor lines. By mounting them both above and below the passing lanes of cans, the double layer of cans in each carton can be checked through the box. Size M30 was chosen to yield the greatest sensing distance for the project parameters. The continuous output from these sensors is connected directly to a PLC with a high-speed analogue input card. Resolution is in the µm range and repeat accuracy is very good. The solution is durable, adaptable, reliable and simple to install.
Busy container seaports rely upon the ‘24/7’ operation of specialist container-handling vehicles called Straddle Carriers for loading, unloading and stacking containers. Often located at ports, being beside the sea can mean that they have to work in an aggressive and corrosive environment, requiring frequent maintenance. Because traditional, interval-based maintenance schedules are not optimally efficient, condition-based intervention systems which minimise the risk of breakdown, are popular. European port operators therefore frequently rely upon Contrinex’s rugged, analogue-output inductive sensors to monitor components with a high risk of premature failure, maximising vehicle utilisation and reducing maintenance costs. CUSTOMER APPLICATION A fleet of straddle carriers services a busy German container port, operating round the clock in a highly aggressive environment. Frequent maintenance is necessary, but traditional, interval-based maintenance schedules are not always optimal. Condition-based intervention minimises the risk of breakdowns, while imposing fewer constraints on day-to-day operation; it also incurs cost only when necessary. As a carrier moves over a container, a central spreader beam lowers and locks onto the four corner fittings of the container. Plain plastic bearings on the carrier legs guide the container as it is raised; there is significant contamination from dirt and other debris. Bearings wear rapidly in the all-weather operating conditions. A condition-monitoring system must measure bearing thickness, repeatably and accurately, in realtime and with µm resolution. Sensors must operate reliably in the harsh environment with a minimum rating of IP67. Sensor length must not exceed 70mm and a minimum sensing range of 30mm is mandatory.
Customer Solution Contrinex’s Analogue Inductive sensors, which feature ‘Extra Distance’ technology are ideal for this demanding application. These M30- diameter metal-bodied devices are IP67-rated and provide an analogue voltage (0 to 10 volt) or current (4 to 20mA) output. The sensors are less than 50mm long with a 40mm sensing range, comfortably exceeding the specified requirement. A mild steel mounting plate, fixed immediately behind the plastic bearing, locates each sensor with its sensing face in contact with the rear surface of the bearing. As a container passes over the front face of the bearing, the sensor measures the distance to the metal container wall, and thus the bearing thickness. Data is collected in real time with exceptional accuracy and resolution in the micron range. Data passes to on-board computers mounted on each carrier; connection is via a flexible cable with an easily detachable M12 connector. At intervals, carriers transmit data wirelessly to a central processor for detailed analysis. The output gives a clear indication of the condition and wear rate of each bearing, identifying any carrier requiring maintenance. Consequently, the port operator has the means to develop a genuine commercial advantage by eliminating compromise from day-to-day operating processes.
