they are adjusted to the rail, enabling the running properties of each carriage to be individually adjusted and controlled. In this application, the GV3 must

withstand high external forces due to the high moment loads acting on the guidance system. At a weight of just under 6kg per tool, these machines operate with rapidly changing velocities; and, in order for the tools to work precisely and remain rigid, the guidance system must operate very smoothly. The GV3 system allows this, with load capacities up to 10,000N. During cardboard processing, dust can

contaminate the guide rail. The design of the V-rail, however, clears dust and debris as the bearings pass across the guide rail. However, since the cutting tools are about 340mm from the guidance system, in reality there is very little contamination on the guide system. The lubrication blocks also help to improve system life.

UNSCRAMBLING BOTTLES HepcoMotion has also helped Packfeeder’s new Pickfeeder Twin 200 unscrambler system to achieve a cycle of 200 containers per minute, while ensuring high reliability and low maintenance. Packfeeder specialises in the design

and manufacture of positioning and sorting systems for plastic containers and bottles, serving industries ranging from pharmaceutical to cosmetics and personal care. Its unscramblers, which are adaptable to a multitude of bottle sizes, geometries and speeds, feature a simple and intuitive design which allows

users to transform the most complex tasks into extremely simple procedures. The first version of the machine offered

160 handlings per minute, but the company needed to increase the machine’s positioning cycles to address the high production and greater flexibility demanded by the market. The new version required a load of 0.5kg for the weight of the product, plus the special design clamp and its relative position with respect to moving the different sections of the circuit. The total perimeter of the circuit is 3m, including the straight sections for five x Beckhoff motors, plus two x 180˚ curves. The circuit is mounted at 45˚ to overcome the forces of gravity in the return of the movers. With a cycle time of 2.4 seconds in an anti-clockwise direction, the system needs to work 16 hours a day, seven days a week, with a guaranteed life of two years. Given the high kinematics of the

application, with speeds of 3m/s, accelerations of up to 30m/s2

, as well as

the 45˚ mounting orientation, Packfeeder required HepcoMotion to design and manufacture a new circuit with reduced weight movers and low friction, without compromising the load capacity, rigidity and precision of the system. In order to reduce the weight of the

movers it was necessary to design and manufacture a lightened aluminium body without compromising its rigidity, and special bearings that provide sufficient load capacity to withstand the demanding requirements of the application. So,


When developing a new inhaler, a healthcare research and development company turned to CME, a designer and manufacturer of packaging solutions. For the project, the company briefed CME on the product, its specification, process requirements and the need for the system to be pharmaceutically compliant for operation within a clean room. To meet requirements, an automated packaging solution that conforms to medical and pharmaceutical standard 21 CFR Part 11 was developed. Here, a suite of two machines, capable of producing a total of 120 parts per minute, accept finished

assembled product from their respective input conveyors. The individual technologies were designed specifically to suit the process and integrate within the machines. Features of the line include hot melt glue applicators, labelling systems, laser coding systems and machine vision systems. These check, inspect and verify 2D matrix codes, colours and alphanumeric text, in the form of a batch code and expiry date, in addition to checking product integrity of the outer card sleeve alignment to the inner product body. The line continues by merging the products onto a single conveyor, prior to passing through a single pack wrapper, and then on to a 10 pack collation system and bundle overwrap for transport. The machines, which feature dual logon digital signatures,

password management and audit trails, check that the correct product is being produced, prior to verifying, reconciling and recording data at each stage. Any rejected items pass through the system with no further added value operations, before being subsequently segregated. The systems also undergo ‘challenge checks’ prior to each production batch to ensure that defects are positively identified.

HepcoMotion worked with Beckhoff to develop a new version of its 1-Trak system to work with the Beckhoff XTS eXtended Transport System. This option meets the high-cycle needs of XTS applications where the requirements of long-term motion profiles and durability are particularly demanding.

GUIDANCE The GFX guidance system for the XTS Transport System provides a good load capacity with precision movement, ideal for processes with high speeds and accelerations. Its low maintenance circuit, comprising straight and circular arc sections and a clothoid curved transition, gives a gentler motion for the movers and allows the machine to run faster and more smoothly than would be possible for a ‘running track’ oval shape. The high- performance load-bearing bearings mounted on the rigid bodies of the movers, along with the magnetic blocks and the encoder vane, ensure good positional accuracy and allow working on curves, optimising the transport system. The XTS eXtended Transport System

uses linear servo motor technology to drive independently controlled ‘movers’ around the circuit. The system offers a solution for complex systems, with high speed movement of up to 4m/s, without compromising on positional accuracy. With its modular architecture it allows the dimensions of the machine to be reduced. Thanks to the total freedom of movement and the high dynamism of the movers, it allows the movers to be synchronised and grouped, giving the system the ideal flexibility for continuous processes. The automatic format change allows the equipment to be adapted easily to the different needs of each product. The Pickfeeder series for robotised

sorting and unscrambling of plastic bottles has been conceived as a modular series configurable for one or more robots, and is compatible with a wide range of applications. The combination of Delta robots with the GFX Guidance System and XTS allows a highly versatile automatic format change machine.
