Previews
Ferris-Wheel Robotic Part Positioners
Yaskawa Motoman Booth N818
Yaskawa Motoman, Dayton, OH, will display new models of its popular ferris-wheel- style part positioners. Two servo-driven trunnion/station axes are on opposite sides of a central sweep axis—one station is positioned in front of one to four weld- ing robots, while the other station is outside the robot envelope where the operator loads/unloads parts. The 180-deg. sweep axis rotates the stations over/under the central axis between the robot(s) and the operator.
New slim-line positioner models have a 17-percent smaller width than standard positioners and are available with 755- and 1255-kg payload capacities. This
design is similar to previous models with an overall positioner width only 1 m wider than the part span (standard lengths are 2 and 3 m); the positioner can rotate parts up to 1.3-m dia.
All three axes are servo-driven, saving cycle time by allowing parts to turn into position while the positioner sweeps. Motion of the headstock in front of the robot(s) can be coordinated to the robot(s) to make circumferential welds while the part rotates. The load station can be jogged by the operator to an ergonomic load position or to facilitate part tracking. www.motoman.com
Custom Hydraulic
Press Solutions
Greenerd Press & Machine Company Booth S4452
Greenerd, Nashua, NH, will show- case its extensive hydraulic press capa- bilities, and have application experts available to
discuss spe-
cific user appli-
cations and
press require-
ments.
With capac- ity to 40,000 tons and bed sizes exceed- ing 240 in., Greenerd presses are available in a variety of styles includ- ing gap-frame and straight- side.
Stop by the booth to learn about its recently completed 200-ton, eight-point gib-guided press for a North American automotive customer adding capacity in Mexico. The press also includes an under-bed mounted eject, and an HMI that features multiple-position stroke profil- ing and hydraulic-flow and pressure con- trol for cam cylinders in the tooling. At press time, Greenerd also is building a similar 500-ton gib-guided press.
