The K option is a new linear motion assembly from Amacoil/Uhing that enables purely mechanical control over ramp-down speed prior to reversal of the drive head.
Available for new installations and, in some cases, as a retrofit to Amacoil/Uhing RG rolling ring motion control assemblies, the K option has applications in a wide range of converting, assembly, metalworking and finishing operations where reversal of the drive head must be smooth, without sudden stops that could jar or vibrate the system, and have an adverse affect on the outcome of the process.
For example, the whip-like action of an extended applicator nozzle attached to the drive head may be prevented using the K option, which would assure a smooth, gradual reduction in linear speed, dissipating the forward momentum of the extension arm before reversing.
The K option is also useful in traverse winding assemblies for fine gauge materials that tear or break easily.
The K option may also be configured to "dwell" for applications where the drive head must be stopped before reversal.
Adjustable hardware "stops" are user-positioned to achieve the desired ramp down in linear speed, independently of the drive motor's rotational speed.
There is no need for electronics or programming.
Additionally, reversal of the drive head travel direction is also automatic and mechanically controlled - independent of drive motor controls.
The K option linear motion assembly features auto-reverse, zero backlash, variable pitch, up to 800lb axial thrust, and accuracy to within +/-0.005in.
Travel speed may be up to 4m/s, at constant rotational speed, over a maximum distance of 5m.
The only maintenance required for Amacoil/Uhing rolling ring assemblies is periodic, light lubrication of the shaft.
Pricing for Amacoil/Uhing linear motion assemblies with the K option starts at under $1000 for basic systems.
Delivery can take up to several weeks depending on the level of customisation required.
