Linear drive assembly reduces downtime
Amacoil/Uhing has introduced a linear drive assembly providing mechanical control over linear speed and travel direction. Used in a variety of converting, packaging, metalworking and other manufacturing industries, the assembly provides automatic, instantaneous reversal without complex electronic controls or programming. Applications include bending, slitting, rewinding, scanning, folding, cutting, coating and spraying.
The drive head travel speed and direction are mechanically controlled independently of the motor, without clutches, cams or gears.
The system does not have to be slowed or stopped in order to change the travel direction or linear speed of the drive head.
This permits the use of an inexpensive single speed, unidirectional motor to drive the system.
Throughput capability is improved because production machinery may be operated for longer periods of time without having to stop and make adjustments.
Besides the on/off switch, there are virtually no other controls, which minimises operator training costs and simplifies maintenance.
The assembly is designed and built to user specifications for production managers and machine design engineers requiring subprocess assemblies for production machinery.
Spray heads, extension arms, vacuuming heads, glue guns, applicators, feed guides, cutters/slitters and other tools, may be attached directly to the load-bearing traversing drive head (nut) - a separate load carrier is usually not needed.
The linear drive which moves the drive head operates on a smooth, threadless shaft which prevents dirt and debris from collecting and clogging or jamming the system.
This eliminates the need to fabricate or purchase a shaft bellows assembly in order to protect screw threads.
The assembly also eliminates backlash because the linear drive uses "rolling ring" bearings which assure constant zero-play, point contact between the bearings and the drive shaft.
The Amacoil/Uhing linear drive assembly provides axial thrust capability ranging from 6 to 800lb, depending on the linear drive model selected.
Travel speed is up to 13ft/s, over distances of up to 16ft.
Accuracy is to within +0.005in and stroke length is user-adjustable to meet application needs.
Options include automatically self-adjusting stroke length, dwell capability and the ability to ramp down/up the tool drive head travel speed.
Amacoil applications engineers are available to provide technical and engineering support.
