WESTERLY, RI | Maxson Automatic Machinery Co. offers an automatic squaring system on its stationary bed knife cutters, or as a retrofit to existing sheeting equipment, relieving the operator of making that adjustment when setting the cutoff. The design reportedly ensures accurate, repeatable positioning is maintained.
An AC servomotor, mounted on a gearhead, is coupled to a fine threaded screw. The servomotor is governed by a microprocessor, which mathematically calculates the squareness for the cutoff setting. The servomotor turns the screw, positioning the cutter head accordingly. Sensors set for the minimum and maximum cutoff range prevent over travel.
Squareness of +0.020 in. (0.508 mm) is maintained, company says. A manual override switch permits the operator to set the sheet squareness, and when returned to automatic mode, assigns the manual setting to memory for the given sheet length.
