Herrmann introduces Ultrarobot, welder
Herrmann Ultrasonics Inc. of Schaumburg, Ill., said its Ultrarobot is a flexible cell for ultrasonic welding of plastic components - using a six-axis robot.
The robot can be supplied by any robot maker, as long as the end-of-arm load and welding forces are taken into consideration when picking the robot.
Herrmann Ultrasonics has developed an end-of-arm weld head that uses two different weld horns to accommodate different welding applications without the need for a tool change.
The company's Windows-based controller, Dialog, touch-controls all welding and interfaces with the robot, without the need for a programmable logic controller.
Herrmann Ultrasonics also started offering its Ultracell mobile workstation to the North American market.
The self-contained unit integrates any of Herrmann's ultrasonic plastic welders. A Dialog touch controller or MPC generator may be mounted on the outside of the Ultracell, eliminating the need to make manual adjustments of welding parameters inside the enclosure.
The company introduced the Ultracell in January at the Medical Design & Manufacturing West show in Anaheim, Calif.
The company also introduced the HSG hand-held welder in North America. Two different grip options allow the operator to pick the most comfortable angle.
This year, Herrmann Ultrasonics is celebrating its 15th anniversary in the United States. It is a unit of Herrmann Ultraschalltechnik GmbH & Co. KG in Karlsbad, Germany.

Process Control Corp. unveils loader, feeder
Atlanta-based Process Control Corp. has introduced a vacuum loader and a regrind feeder.
The CA-series vacuum loader is a small, self-contained unit that conveys up to 800 pounds per hour of material.
The economically priced CA can be used to load pellets, regrind and granular materials.
The loader features a high-efficiency cyclone mounted on a clear-view tube with a mounting flange, an air-flow amplifier, an exhaust-air filter and a control box.
Loading is controlled by a proximity sensor mounted in the view tube. The direct-mount design is ideal for machine-side loading, and eliminates the need for bulky, machine-mounted surge hoppers.
The regrind feeder works with Process Control's Guardian line of gravimetric batch blenders. The auger-type feeder moves hard-to-flow sheet regrind in in-line thermoforming of ground-up scrap from sprues and bad injection molded parts.

Vecoplan shredder garners U.S. patent
Vecoplan LLC of High Point, N.C., received a U.S. patent Jan. 4 for its FF series of rotary shredders, designed for film and fiber.
Vecoplan said the FF machines are the first shredders capable of one-pass size reduction of film and synthetic fibers to a desired consistency. Those materials tend to wrap around cutting rotors.
The patents cover the ``SureCut'' cutting technology, which uses a double row of primary cutters augmented by auxiliary nip cutters that prevent wrapping, a wedge bed knife, a close-tolerance robot and a reinforced screen.

Comet drying system uses honeycomb rotor
Comet Automation Systems Inc. is bringing its honeycomb-rotor drying technology to molders of polycarbonate optical discs and lenses.
The honeycomb is a ceramic fiber impregnated with silica gel. The material is mounted inside a rotor that continuously turns at a slow speed, to absorb and remove moisture from air moved through by a blower. The rotor then moves through regeneration and cooling zones before moving into place to pick up more moisture.
Dayton, Ohio-based Comet is marketing its SAN honeycomb dryer as faster and more consistent than desiccant drying, without the spikes in temperature and dew point. Honeycomb dryers also have a service life of up to 15 years, compared with desiccant dryers, where the dessicant must be replaced about every two years, according to Comet.
The honeycomb is the only moving part on the dryer.
``This will be the first alternative-type dryer for optical discs,'' sales manager Sam Rajkovich said in an interview at Comet's headquarters.
Rajkovich said drying is important to makers of lenses, compact discs and DVDs because moisture can cause blurring on the optical part.
Comet said it has sold more than 2,000 of the honeycomb dryers since introducing the unit in 2001.
In other news, Comet introduced a small, lightweight compressed-air dryer for consistent drying of colors and other additives.
The Micro ADS (for additive drying system) makes color changes easier when molding smaller parts.
The design makes it easy to remove a color from the dryer or pull off one unit and replace it with another one with a different color, the firm said.

Redesigned conveyor includes controller
FKI Logistex North America of Cincinnati, which makes materials-handling systems, has redesigned its Accuzone 24-volt motorized roller accumulation and transportation conveyor.
Changes include a stand-alone and programmable DeviceNet networked controller that enables fully modular wiring, eliminating more than 20 electrical connections per 10-foot Accuzone section.
Other changes include improvements to the merge-and-divert module sizes for easier handling and configuration. A plastic side frame cover now encases wiring and controls.
In other news, FKI Logistex has opened an office in Mexico City. The company said it has 150 lines in Latin America.

Ogilvy device allows inexpensive assembly
Ogilvy Assembly Tooling said its new hot-air/cold-stake design is an inexpensive way to assemble plastic parts, saving thousands of dollars because it eliminates the need for press tables, used on standard heat-stake machines to move parts up to the heat-staking area.
The device also has a built-in control system that easily can be configured to suit each manufacturer's needs, the firm said. Other features include a thin profile that takes up little space and a stand-alone design so it can be incorporated into other machinery.
Ogilvy is based in Lapeer, Mich.
