Honda MPR Overview

---

PLCs, weigh scales, vision sensors and USB cameras can control the part counting and label-printing processes. Vision sensors and cameras can validate parts for correctness, and trigger the conveyor to divert suspect parts. Touch-screen PCs provide real-time visibility into lineside processes. These technologies are all net-worked to ensure accuracy at every step, every shift, every day.

Serialized WIP /internal labels are printed on-demand, enabling WIP units to be uniquely tracked, provide visibility and ensure the WIP unit proceeds in the correct sequence from the first operation to the last. Traceability records are created automatically to enable each WIP unit to be easily traced back to its raw components, and forward to the finished part. 

Serialized container labels are automatically printed at line-side, triggered by input from a PLC, Weigh Scale, Vision Sensor and/or USB Camera when the pack count or dunnage is correct. Cameras can provide video to confirm that packing requirements were met in case of customer inquiry. Label data is supplied by the host ERP/ EDI system. Back /forward Traceability records are created automatically.

Individual parts and containers of parts can be serialized at line-side. 2D serial numbers on parts can be read by vision sensors as the parts are counted and packed. Part serial numbers are linked to the container serial number in which they are packed. The container serial is linked to production details including machine, run date, lot, shift, etc. , providing detailed traceability.

At a re-pack station, there won't be a PLC to validate the correctness of parts being packed into a container. Instead, a vision sensor can confirm each part is correct, alert the operator if an error is being made, and optionally trigger the conveyor to automatically divert the wrong part. When a pack count of good parts is reached, a serialized container label will print automatically. 

A vision sensor can count the parts leaving production and identify good parts vs. scrap. By interfacing to a conveyor, good parts are diverted for packing and labeling, and scrap parts are diverted for re-work. The re-work parts are controlled via serial number on the Part /Container. Serial numbers provide traceability.
