Productivity linearly increased

The Linear Motion System (LMS) enables individual control of each single workpiece carrier and processing directly on the transport unit.

Linear Motion System from Rexroth reduces unproductive delivery times

In high-volume production, users achieve a considerably higher productivity by means of lower transport times with the Linear Motion System (LMS) from Rexroth. The system is based on standard linear motors, where the workpiece carriers can be run independently. It positions workpieces precisely to within 10 µm, so that processing can start immediately without correction or transshipping to another assembly platform. This reduces unproductive delivery and idle times.

In high-volume production of microchips, the LMS already proved to be extremely reliable. Now Rexroth provides the system solution also for other applications, for example in the automotive industry, and is finely scaled to cover workpiece weights from one up to 1.000 kilograms. With several motors, users flexibly assemble also longer process lines as an oval, as parallel lines or in different levels. Thereby, they can also combine the LMS later on with existing transport solutions like conveyor belts.

The system displays complex movement patterns that, for example, are necessary with different cycle times in the several process stations. The individual workpieces here follow individually defined speeds and positions. Due to high dynamics and speeds from up to 6 meters per second it reduces the delivery times compared to conveyor belts.

The unproductive idle times decrease additionally, because processing and assembly steps are possible directly on the transport unit. Whereas, with common transfer systems the carriers need to be unloaded at the individual stations and transferred into a processing position. This is no longer required with LMS, whose transport units steadily remain on the defined position, without affecting the flow of other workpieces. The linear motors operate without contact and thus maintenance-free. Furthermore, LMS requires less carriers compared to conventional systems. This reduces overall system costs due to a lower number of necessary Ident systems, sensors and actuators.
