SPS IPC Drives 2013 exclusive show report

06 January, 2014
has extended its VLT OneGearDrive ExtensionBox for geared motor applications such as conveyors with torque requirements of up to 1kNm. A simple 3:1 torque arm connection between the gearbox and OGD (shown below) allows higher torque levels to be achieved using the same number of motor variants, thus reducing parts inventories and manual conversion work. The oil-free system is said to be almost maintenance-free. Torque is transferred by a Kevlar toothed belt thus avoiding the drawbacks of gear stages.

The Swiss linear motion specialist Linmot was previewing a new series of linear motors that incorporate an encoder and servodrive, thus minimising wiring, and saving time, space and labour costs. The PSC01 motors will be able to deliver peak forces of up to 255N.

Linmot also has a new linear rotary motor with gearbox for torque requirements up to 80Nm. The gearbox allows precise, dynamic positioning, even for loads with high moments of inertia. Linear and rotary movements can be actuated independently of each other or synchronised using a higher-level controller.

SENSORS AND MEASUREMENT

Balluff has a rugged new magnetic linear measuring system which, it claims, can be used where optical systems would previously have been needed. The IP67-protected BML-S1G system consists of a magnetically encoded tape and sensor head. It offers resolution ranges of up to 1µm at system accuracies up to ±20µm and travel speeds up to 10m/s, over distances of up to 48m. The sensor has a BISS-C or SSI interface and can produce real-time analogue or digital signals.

Also new from Balluff is a vision sensor claimed to handle almost any inspection task. The BVS-E Universal sensor (above) has built-in processing electronics, lighting and two digital outputs, and can inspect many characteristics in one pass. It can simultaneously gauge brightness, compare contrasts, count edges, check positions, detect patterns and read codes. It can locate, read and verify up to 40 codes per second.

Baumer has expanded its NextGen portfolio of sensors to include ultrasonic types that are that are identical in shape and size to its O500 photoelectric devices, allowing them to be interchanged easily. The U500 ultrasonic sensors – available in proximity, distance measuring and reflective light barrier versions – have a 1m range, claimed to be the longest in its class. They can detect almost any object and have a narrow beam, allowing them to be used in cramped spaces.

Baumer also has a new range of inductive sensors that have the same sensing distance for all metals, simplifying adjustments and minimising the risk of damage. The Factor 1 sensors come in four cylindrical sizes from 6–18mm and have switching speeds of 0.5–3kHz. Finally, Baumer has a new range of programmable encoders (EIL580P) that can provide any pulse number from 1–65,536.

Belden has extended its Lumberg family to include IP67-protected machine-mounting distribution boxes that provide connections to sensors and actuators in demanding environments. There are more than 20 versions of the boxes, with four or eight vibration-proof M12 ports.

At SPS, Datalogic launched a family of photoelectric sensors for diffuse proximity detection of transparent objects without needing a prismatic reflector, even for reflective materials such as glass. The S8 sensors, which include a patented background-suppression technology that can handle moving backgrounds, are available in laser versions with a range of 50–150mm or LED versions with a range of 100­–300mm.  

Datalogic also has a new generation of IP67-protected smart cameras for food, beverage and pharmaceutical applications. There are two families: the general-purpose A30 version with
