MECHANICAL COMPONENTS APPLIED TECHNOLOGY NEW TABLET COUNTING MACHINE SLIDES INTO ACTION
PRT2 precision rings and GV3 linear slides from HepcoMotion have been selected by Pharma Packaging Systems for a new counting machine with tare gross weighing system. The demand for the new PC180 counting
machine arrived at Pharma Packaging via an application based on substitute narcotic tablets for a pharmaceutical customer in the USA. The system, however, had to be quick and accurate. The PC180 system indexes empty containers
three at a time, weighs them and records the weight (tare). The containers are then indexed again and filled with a counted number of tablets. Another index sees the containers being weighed once more. Finally, the tare weight is subtracted from the product weight and the system identifies containers that either comply with the target weight or fail. Good product advances to an out-feed conveyer, while failing product is diverted down a chute to a reject area.
The PRT2 precision ring system is
based on HepcoMotion’s V guide technology and features an integral rack and pinion drive, which facilitates the precise indexing mechanism thanks to its friction-free, zero-play motion. The company has found this to be very easy to design around. Ian Barnes, technical director, explains: “It has allowed us to do away with the centre bearing mounting. This means we can run the conveyor through the centre – it doesn’t need to be offset – thus enhancing accuracy because containers that are not at 90˚ to the centreline can sometimes be a problem. We also like the fact that the PRT2 can run dry, without any need for lubrication, which is very important for pharmaceutical applications.” GV3 linear motion V guide and actuator systems
are also used for two different applications in the machine: in a vertical configuration to raise and
lower the filling nozzles, thus accommodating different container sizes; and in a horizontal configuration to guide pneumatic cylinders which actuate gates that allow tablets through before closing-off for the next batch. All Pharma Packaging Systems equipment
complies with the latest cGMP requirements and is fully validated including 21CFR Part 11 compliance (where applicable).

Enter 201 A LATCHING SOLUTION FOR THE SELF-SERVICE POSTAL SECTOR
As a provider of self-service solutions for the postal sector, Denmark-based aCon’s offerings include the Self Post Unit, designed to supplement or replace personal post office services; and the Self-Service Post Office, which combines a Self post Unit and a Self Post Locker. In the Spring of 2013, the company introduced Swipbox, which consists of a network of indoor parcelterminals, designed to offer an enhanced delivery wh ich would bring e-retailers and their customers closer together and make delivery a value-added part of the buying experience.With this, however, the company wanted to offer retailers a completely secure delivery concept wherethey could be confident that high value items purchased by their customers were not at risk of theft or vandalism. To help, Southco provided the R4 EM electronic rotary latch. Easy to install and maintain, the R4 EM delivers the convenience of electronic access control with the security of
proven, metal rotary latch design in a compact, integrated package. Its electric gear motor delivers major advantages over solenoid driven latches in terms of efficiency, through low electrical power consumption and high working and ultimate load capabilities, the company explains. A mechanical override feature also enables manual or emergency release in the
event of a power failure. Offering vandal resistance, durability and reliability, the R4 EM has an embedded microprocessor which enables signal conditioning for added security. Furthermore, it will accept signals from access control devices, such as numeric keypads or swipe-card readers, smart card reader devices, biometric devices and remote computers. Swipbox is already enjoying success across Denmark, with popularity at major public areas such as universities and supermarkets.
