Packaging Newsletter: sandi test

September 13, 2007

In this June issue of the Packaging Newsletter from Machine Design there are articles on the importance of vents in containers and on a new packaging machine that doesn't use filler material.

The highlighted products are ironless linear positioners and a motion control ICS.

Be sure to check out the industry update to find out about a packaging safety conference next month. Thanks for reading and have a great day!

Even containers gotta vent

The right kind of packaging vents can eliminate expensive maintenance and regulatory issues by letting off a little pressure. Collapsed or bloated containers, condensation, damaged labels, and containers that simply refuse to open have one thing in common: They're bad for business. Package redesign may seem the obvious solution. But many engineers do not realize these problems stem from pressure difference that create vacuums in sealed containers. For over 25 years, thermally stable ePTFE membranes have satisfied a wide variety of airflow and liquid-resistance needs in the packaging industry.

Say Goodbye to Styrofoam Peanuts

B+ Equipment, France, created Ultipack, a machine that wedges a corrugated cardboard blank over articles in boxes for shipment. Ultipack glues a distortable corrugated blank inside the box with hot-melt to secure the items for shipping and offers the same protection despite machine throughput, box-filling ratio, articles weight, or storage time after shipping. The corrugated wedges cost, on average, four times less than void fill material such as Styrofoam peanuts or inflated bags. The tray and lid combinations also cost an average of 20% less than standard RSC boxes.

New Products

Ironless Linear Positioner

Built around the 110 model of the Trilogy I-Force ironless motor, the T1D and T1S are ready-to-run positioners with selectable single or dual-square rail bearings. The four main elements of the positioners are the linear motor, linear bearings, linear encoder, and mechanics (base, carriage plates, bumpers, brackets, and cable track). In addition, they are designed to connect together using transition plates for XY or multiaxis configurations. Options include a variety of cable-management systems, optical or magnetic encoders and drive connectorization. Typical applications are in lab automation, small vertical axes, medical devices, printing, lightweight scanning/sorting, microscopy, and light assembly. Key standard features include 110 Series motor, aluminum base, selectable thickness for rigidity and stiffness, peak forces in two sizes to 46 lb (203 N), continuous forces to 10 lb (45 N), travel lengths to 33.6 in. (853.44 mm) in 2.4 in. (60.96 mm); speeds to 180 ips (4.5 m/sec), and accelerations to 6 g.

Motion-Control ICS

The Magellan family of motion-control ICs with seven-segment S-curve profile generation come in one, two, three, and four-axis versions. The programmable chips eliminate oscillation, reduce vibration, and reduce the change in acceleration for less wear and tear on the system and faster transfer times. The ICs accept position, velocity, and acceleration from the host to generate a corresponding trajectory. Communication is through a host microprocessor with an 8 or 16-bit parallel bus, CANbus 2.0B, or asynchronous serial port. Features include programmable PID filter with velocity and acceleration, feed-forward, 32-bit position error, dual biquad filters, 50-µsec loop time, and multichip synchronization. Trace capabilities give designers on-the-fly data storage for analyzing system performance, tuning servo-filters, and performing maintenance and diagnostics. Available in a single-IC/single-axis version or a two-IC/multiaxis version, the ICs are packaged in a 144 and 100-pin TQFP.
