Cable Retraction System

The triflex® RSE pullback system from igus (East Providence, RI) uses a simple linear retraction without bends, fiber rods, or rollers. The system consists of a drylin® linear guide with carriage, elastic cord for retraction, fastening plates for connection to a variety of robot types, mounting bracket without strain relief for the respective e-chain size, and gliding feed-through for the respective e-chain size. The product is available for triflex sizes from 60-125, all of which can be mounted on one system. The linear system has fewer deflection points, and consequently provides better process reliability for laser light cables and supply hoses.

Collaborative Robot

Kawasaki Robotics (Wixom, MI) introduced the duAro collaborative robot. The dual-arm, horizontal articulated robot can safely collaborate with humans in work operations due to its low-power motors, soft body, speed, and shared work zone monitoring. The single-axis configuration provides independent arm operation with ±0.05 mm repeatability and a payload capacity of 2 kg per arm. Use of both arms in coordinated movements increases the robot payload capacity to 4 kg. The base of the robot is on wheels and accommodates the controller. The robot is designed to be installed in a single-person space, so it can be deployed without modifications to the assembly or manufacturing line. A direct teach function lets users teach the robot tasks by hand-guiding its arms, or the robot can be programmed using a PC or tablet terminal by entering numerical values indicating the direction and distance of each movement.

Auto Crash Sensor

Meggitt Sensing Systems (Irvine, CA) introduced the Endevco model 7264H optimally gas-damped accelerometer for automotive safety testing. The sensor is small in size and mass, and eliminates irrelevant frequency content generated by breaking glass and metal-to-metal impact. The MEMS accelerometer performs consistently over temperatures ranging from –18 to +66 °C (0 to 150 °F), and has a .50:.85 damping ratio and a 10,000g shock capacity. The frequency response is flat from DC to 3,500 Hz. It has a two-active-arm, full-bridge circuit with fixed completion resistors to facilitate shunt calibration. The full-scale output is 200 mV nominal with 10 Vdc excitation. The accelerometer comes standard with 2-, 5-, and 10-volt calibration data.

Air Compressor

Gardner Denver Thomas (Sheboygan, WI) offers the 2380 series twin WOB-L® piston oil-less air compressor designed for pressure/vacuum and high flow. It provides 100 psi (6.9 bar) maximum pressure with open flow of 2.3 cfm (65 l/min). The air compressor is fan-cooled and has a one-piece monolithic head. Weighing 12 pounds, it is 9.31" (236.5 mm) long × 5.14" (130.6 mm) wide × 6.73" (171 mm) high. The twin-cylinder design helps provide reliability, low vibration, and quiet operation.

Rotational Speed Sensors

RHEINTACHO Messtechnik GmbH (Freiburg, Germany) introduced the FQ series of plastic sensors for detecting rotational speed and direction. The sensors feature an IP69K protection class rating, which means they can withstand powerful, high-temperature water jets. The sensors offer different cable lengths, connectors, cable outlet directions, detection distances, and EMC. Standard insertion depths are 30, 35, and 45 mm. The sensors have a frequency range of 0.1 Hz to 20 kHz, and an operating temperature range of –40 to +140 °C.

Collaborative Robot

Rethink Robotics (Boston, MA) introduced Sawyer, a smart collaborative robot designed to execute machine tending, circuit board testing, and other precise tasks. The robot modifies its behavior to respond to changing and unexpected conditions on the plant floor. The robot weighs 19 kg (42 lbs.), and features 7 degrees of freedom with a 1260-mm reach that can maneuver into the tight spaces and varied alignments of work cells designed for humans. Its compliant motion control allows it to “feel” its way into fixtures or machines, even when the position varies slightly. The robot’s precision is ±.1 mm in semi-structured environments. An embedded vision system uses a head camera for wide-view applications and a Cognex camera in its wrist. The robot features a face screen to help it communicate with co-workers, and a train-by-demonstration user interface.

Manufacturing Connectivity

Sandvik Coromant (Fair Lawn, NJ) introduced the CoroPlus™ platform for connecting manufacturing tools and software. The platform gives users access to product and application data through connected software and hardware from pre- to post-machining. Sensor-equipped tools let users adjust, control, and monitor machining performance in real time. The entire machine shop can be controlled via on-site data dashboards, through the cloud, and via integration with the user’s software and machine environment. The platform connects into existing software environments through open APIs, offering two-way connectivity.

Part Positioners

Yaskawa Motoman (Dayton, OH) expanded its line of RM2 ferris wheel-style robotic part positioners. The positioners have two servo-driven trunnion/station axes on opposite sides of a central “sweep” axis. One station is positioned in front of one to four welding robots, while the other station is outside the robot envelope where the operator loads/unloads parts. The 180° sweep axis rotates the stations over/under the central axis between the robot(s) and the operator. Slim-Line positioner models have a 17% smaller width than standard positioners, and are available with 755-kg and 1,255-kg payload capacities. Extra-large-capacity positioners were designed to provide higher payloads and turning diameters in a reduced profile, and feature 1,555-kg and 2,355-kg payload capacities.

Optical Encoders

MICROMO (Clearwater, FL) announced the FAULHABER high-precision IER3 and IERS3 optical encoders. Both encoders deliver two-channel quadrature signals and an additional index signal. They can position a FAULHABER micro DC motor or brushless DC servomotor with a typical accuracy of 0.1° to 0.3°. The encoders combine the LED, photodetectors, analysis unit, and interpolation levels on one chip. They lengthen motors by 15.5 to 18.5 mm. Both encoders are also available with line drivers that generate complementary output signals and make data transmission resistant to electrical interference, especially in encoders with long connecting cables. The IER3 encoder has a resolution of up to 10,000 lines per revolution, and achieves an angular resolution of 0.009° with the evaluation of 40,000 edges per revolution. The IERS3-500 provides resolutions of 250 and 500 lines per revolution.

Product of the Month: December 2016

ANSYS AIM 17.2 simulation software from ANSYS, Pittsburgh, PA, features combined fluid thermal and solid thermal-stress capabilities. Momentum and heat sources are available for fluid and conjugate heat transfer analysis, enabling simulations to include such features as electronic package power sources, fans, and filters. New options for optimizing bolted connections allow engineers to model loading and bolt tightening sequences for structural assemblies. Integrated geometry modeling enables users to open data from any CAD system for simulation. Automated meshing tools allow rapid generation of meshes for complex geometries. A flow solution evaluates parameters such as reducing pressure drop, calculating lift and drag coefficients, and evaluating fluid loads. Other features are stress, vibration, and durability analysis; electromagnetic simulation; and simulation of polymer extrusion manufacturing.
