Yamaha’s answer to Next Generation of Production Line design

Linear Conveyor Modules LCMR200 Advanced linear conveyor module with high speed transport. -Repeatability : ±5μｍ -Maximum speed : 2,500mm/sec (When the conveying weight exceeds 10 kg, it will drop to 2,000 mm/sec according to the weight.) -Minimum spacing between robot sliders : 210mm

Adding productivity to transportation process
Convert transfer process into “value-added” assembly process

Comparison of conventional conveyors
        From ordinary “passive flow” to “active position transport”. By converting conveyor flow into active production process improves profitability.

        1. Reduce transport time. <Comparison between LCMR200 and a conventional conveyor>

        2. LCMR200 vs Conventional Conveyor System

Structures
      Superior performance that improves the transfer environment.

        1. No origin process needed

Newly developed high-precision full-range absolute server eliminates the need for return-to-origin. The operation can be started and stopped easily, so there is no time loss even when starting or restarting.

        2. Easy modular connection with Connecting Plate and Connecting Unit

Mechanical connection by Connecting Plate and signal communicating by Connecting Unit. Simple yet, secured connecting method of modular system

        3. Saves space through proximity installation of forward and returning modules

                <Cable extraction direction can be selected Front Rear>
                The cable extraction direction of a module can be selected. When installing on a device, it increases the flexibility of electrical wiring layout. Especially in the horizontal circulation layout, by making the cable extraction direction reverse in the forward and returning modules, the modules can be positioned as close as 200 mm apart at most, and therefore, cycle time reduction is possible at circulation and installation space can be reduced. The LED indicator that shows the module state can be visually checked from both front and rear side of the module.

        4. Low profile structure

By adopting a newly developed linear motor, the module height is approx. 30 % down compared to LCM100. The space under the frame can be effectively utilized.

        5. Built-in driver saves electrical wiring
                Motor driver is incorporated inside module and entire LCMR200 is controlled by YHX controller through YQLink cable. It also contributes to space saving inside the control panel.

         6. All the sliders can be operated / programmed independently.

Speed and acceleration can be programmed by each move. All carriages can be controller individually.

         7. Top enclosure design for protection.

Top enclosure was designed to protect internal mechanism from any fallen object during line setup process.

        8. Mechanical tolerance between sliders +/-30 μm (Dowel hole standard)
                Due to tis machined accuracy, each carriage has own tolerance at one stopping point, however, LCMR200 can limit the slide machine difference to +/-30 μm, and is suitable for high precision process. As RFID, etc. is not necessary, cost reduction is possible.

Realization of productivity improvement 
      Versatile and value added transport between work process. Improve cycle time and reduce line floor space. Increase productivity and cost performance.

      1. Process sharing
      -Carriage is bi-directional and one work station can perform more than one task. Saving total line cost and floor space.
      -High speed bi-directional move and simultaneous independent operation of multiple carriages.

      2. Variable speed control between work stations.
      -Servo controlled direct drive eliminates mechanical stoppers and position sensors.
      -Simple position setting by entering point data in a program.
      -Flexibility in setup for production lot change
      -Saving flow time by narrow pitch incremental move and high speed move.

      3. Assembly can be done while parts are on conveyor
      -The highly rigid guide enables assembly and processing on the transport line.
      -No need to reposition parts to/from conveyor. Floor line space is reduced substantially.

      4. Easily serviceability = Easy troubleshooting
       -Covered structure of module keeps internal mechanism free from foreign objects
      -The environment-resistant magnetic sensor is resilient to contamination.
      -Easy positioning with no precision setting.
      -Non-contact motor and linear scale design eliminates mechanical wearing
      -Low particle generation (only mechanical contact is guide rail)
      -Standardized components reduce spare parts SKU.
      -Parts can be replaced easily.
      -Operation can be restored just by replacing the slider or linear module, and the manufacturing line down time can be kept to a minimum.

Yamaha genuine circulation unit

        Sleek and simple configuration. Simplified line design process with flexibility and efficiency by modular concept.
                All carriages and peripheral linear robots can be controlled by PLC through one YHX controller.
                -Layout example with a combination of the module and circulation unit.

     Circulation unit

Circulation units are available as standard. Because the circulation units are manufacturer's standard products, the stable operation of the production line is achieved without worrying about module "deviation". Furthermore, you can also save time and effort in design.

     YAMAHA genuine circulation units achieve the stable operation of the production line.

     Circulation unit features

       - POINT 1 Measures against “deviation” necessary to maintain the accuracy are taken thoroughly.
                Maintaining the accuracy is very important for transfer sections, but is not easy since “deviation” may occur. Use of YAMAHA genuine circulation units makes it possible to eliminate such “deviation” and maintain the accuracy.

       - POINT 2 Easy adjustment
                The end plate that positions the module on the main line side is shipped with the accuracy adjusted, so the adjustment is completed by simply enabling the accuracy correction function. After installation, the work you have to do is only teaching.
                *The module on the main line side is positioned by the end plate.
