DURABLE ROLLER CHAINS MEET PACKAGING INDUSTRY APPLICATION DEMANDS
Tsubaki, the precision engineered roller chain specialist, offers a range of long life, durable, chains suitable for use in the packaging industry. Designed and manufactured for optimum durability and lifetime, the company provides roller chains to machine builders and users across sectors including packaging lines, industrial packaging, labelling and bottling, as well as logistics and automation. It offers, for example, a gripper chain range
for form, fill and vacuum seal operations. The chain’s durable springs have been developed to last for more than ten million high-speed cycles and the M-type attachment’s side-swivel design, which can be combined with Tsubaki sprockets, enables highly smooth
operation for optimal material feed-through. With
recessed riveted pins for easy chain length adjustment, the gripper chain is also easy to install with a spring clip fitting. In many food packaging applications, the risk of contamination
prevents roller chain lubrication, resulting in accelerated chain deterioration and productivity-stopping breakdowns. To resolve the issue, Tsubaki has developed its Lambda roller chain, impregnated with NSF-H1 food-grade lubrication to protect against friction. Special sintered bushes retain the lubricant, preventing contamination while prolonging chain life. Also available is the Neptune anti-corrosion roller chain. Suited to packaging lines that
require hygienic operation and undergo regular washdowns with aggressive detergents, the Neptune chain includes a two-layer surface treatment that prevents rust. The chain is tested to 700 hours of saltwater spray and 2,000 hours of sodium hypochlorite and sodium hydroxide exposure, both of which are used in the food industry to clean and disinfect. The Neptune is also offered in a lubrication-impregnated Lambda version. To ensure exacting chain measurements for pairs and multiples of chains used
together on packaging machinery, Tsubaki provides a Match & Tag service. This guarantees a maximum chain length difference of just 0.5mm that optimises chain synchronisation for new machines and facilitates a fast, duplicate replacement for retrofit. The company
showcased its chains for the packaging industry at the PPMA exhibition this September.

ARMOURING PROTECTS BELTS IN HEAVY DUTY APPLICATIONS
In heavy duty applications such as in mining, recycling, and biomass power plants, excessive belt wear often occurs. In fact the highest wear part on an Overband Magnet is the belt that transfers the separated metal away from the conveyor and into a collection area. To combat the excessive wear and extend the life of a self-cleaning belt, Bunting’s engineers designed a lightweight but heavy-duty armouring for the belt. This is said to provide unrivalled protection, significantly lengthening belt life. An Overband Magnet sits over a conveyor transporting
materials such as aggregate, waste, shredded wood or mined ore. The magnetic field of the Overband Magnet, generated by either a permanent magnet or an electromagnetic block, attracts ferrous metal from the conveyed material up and onto the revolving self-cleaning belt. Rubber upstands on the belt catch the lifted metal, transporting it away from the conveyed material into a separate collection area. The force of the ferrous metal striking against the self-
cleaning rubber belt is significant due to the magnetic attractive energy of the permanent or electromagnetic block increasing as the metal moves closer to the face. The moving belt becomes sandwiched between the lifted metal and the magnetic block momentarily, until the upstand catches and drags the item away and out of the magnetic field. The new armouring on the rubber belt is comprised of high- density polyethylene (HDPE) slats. Each slat is 100mm wide and 10mm thick, with a length to suit the model of overband magnet. The slats are fastened to the belt using special 304 stainless steel elevator bucket bolts and nyloc nuts.

PULLEY ADDED TO EMERGENCY PULL-WIRE SWITCH RANGE
With emergency pull-wire switches, often used along conveyor belts, one pull on the wire and the machine part comes to a safe halt. As long as the conveyor is running in a straight line, the wire can easily be tensioned within the maximum approved deflection over distances of up to 2 x 100 metres. So when a manufacturer of airport luggage
conveyors needed a solution suitable for conveyors which go round bends, or in other extensive and non-linear hazardous areas, it turned to Steute. To help, the developers in the steute business
division Controltec came up with a simple and effective solution: the Multiflex 4R pulley. This has now been added to the steute range of emergency pull-wire switches. The head of this pulley, guiding the wire, can be

rotated to any position. The Multiflex 4R thus provides a wire guide suited to conveyors which twist and turn in different directions. Even when the pulley is deflected multiple times, the friction is minimal, helped by the mobile rollers in the cavity of the pulley. The system complies with a maximum deflection force of 200N in conjunction with a maximum deflection of 400mm, as required by EN 60947-5-5. Pulling the ‘ripcord’ to actuate the emergency-stop function is comfortable, wear and tear is minimal, and even longer pull wires can be deflected multiple times without requiring a high actuation force. An M8 thread in the foot of the pulley facilitates
simple and universal mounting of the Multiflex 4R. Alternatively, it can be fixed to conventional profile
systems, e.g. conveyor systems, for transporting packages and luggage, using a slot nut. Following this application, there has also been
interest from many other areas of industry using conveyor technology, including in tunnelling.
