In response to its drive to reduce the amount of cabling in servo motion systems, Kollmorgen has introduced the SFD3 digital resolver. Supplied as scalable motion

control packages, the single cable solutions are available with high-resolution Hiperface DSL absolute encoders or a digital resolver (SFD) feedback option. The range includes standard servo drives and those with integrated motion control, so that hardware and wiring requirements can be reduced. As a result, the company can implement single-cable technology

with an eight-pole standard motor cable – three phases, one PE, two for the brakes and two for the feedback system. Due to the high interference resistance, data can be transferred safely within the cable without EMC interference problems. The company has created a system in which motors with digital resolvers or Hiperface DSL encoders and drives can be connected with one single cable type. The range is available in a number of packages including: ones

with the AKD-N model servo drive, and the AKMH fully hygienic stainless steel servo motor, the AKD drive and AKM washdown gear motor for food industry applications; the low-cost AKD drive and AKM motor package; a package including the AKD Basic drive, and a package with the AKD PDMM servo drives with integrated multi-axis motion control and built-in PLC. The solutions are available from Inmoco.




As a manufacturer of drive and attachment chain, Tsubaki offers solutions for drive, conveyor or attachment applications which meet pharmaceutical as well as food and beverage industry standards. One example is lube-free, oil

A new size 8 range of miniature hybrid stepper motors has been introduced by Astrosyn International Technology. There are two models in the range which can be configured for unipolar or bipolar drives – the smallest has a body length of only 30mm, while delivering a holding torque of 1.7N cm. The 47mm version provides a 3.2N cm holding torque. All the models offer high accuracy with a step angle of 1.8deg. Applications for the motors

include modelling, gaming equipment, robotics, laboratory sampling and medical instrumentation, as well as controlling CCTV cameras in security applications.

impregnated, sintered roller chains. With these, there is no need for external lubricant and they can extend the wear-life of conveyor equipment dramatically, the company claims. Such conveyor chains also protect food products and packaging, as well as equipment, from marking and contamination. In packaging machinery, lube-free or ‘internally lubricated’ chain will retrofit directly into standard ANSI, BS and DIN sizes. An alternative is Plastic

Combination (PC) chain. Constructed from engineering plastic, this has solid extruded plastic inner links with stainless steel bearing pins and outer link plates, ensuring strength. Being a bush chain, debris can be cleaned off easily. It is also quiet and requires no lubrication. In facilities using

thermoforming machinery – including food and medical

product manufacturers – gripper chain is used to feed the film over the semi-packed product before it is sealed. Tsubaki’s gripper chain uses an advanced spring design with increased fatigue resistance as well as a side-swivel gripper design which creates a wider opening and improves the plastic film feed. The company has recently

introduced a food grade lubricant for its NP series of Gripper chain which has been proven to provide the same wear resistance properties as the rust preventative agent used previously. Also available is N.E.P. chain,

which is suitable for use on systems that operate in applications involving corrosive

chemicals, temperature extremes, excessive moisture or saltwater, resulting in excessive corrosion, wear and reduced performance if they are not suitably protected. The N.E.P. chain undergoes a special surface treatment to ensure that all the components in the chain have the maximum protection for operating in corrosive environments. The N.E.P. chain is available in both BS and ANSI specifications and in the Lambda Lube-Free design. The chain does not contain any chemically hazardous substances and has a working temperature range from -10˚C to +150˚C. To ensure reliable performance above +60˚C, a special high temperature lubricant can be applied. When chains are running in parallel for conveyance purposes, for example on packaging machinery, it is essential that they are exactly the same length. To help, Tsubaki offers a Match & Tag Service, which guarantees a maximum chain length difference of just 0.50mm - independent of the overall chain length.

SHOOTING MACHINE DESIGN Laempe & Mössner is now equipping its core shooting machines with Rittal’s support arm and housing systems. The system features a programmable logic controller which manages all processes

within the system, while the human-machine interface comprises a panel PC with a touch screen. This enables the user to operate the equipment and to monitor current status. Other elements – such as an emergency off switch, signal pillars, valves and a pressure indicator – are also required, and these are contained in compact housings from Rittal’s Comfort Panel range. Each housing is divided into three sections – the panel PC is mounted in the

centre, while the lower third accommodates the switches, signal pillars and other control and display elements. The top part contains pressure and vacuum indicators, plus valves to control the pneumatic and vacuum systems. This logical arrangement, coupled with a spacious housing layout, enables a significant degree of standardisation. A solution based on Rittal’s CP 120 support arm system is used to mount the housing securely on the machine. The support arm system is said to be both robust and reliable.
