Sweetnight Smart Manufacturing MES

A shopfloor Manufacturing Execution System designed specifically for smart mattress production lines, polymer foam compounding, and sleep hardware IoT integration.

1. Industrial Context & Shopfloor Realities

Bedding and sleep technology manufacturing is an engineering-intensive process with distinct industrial requirements:

  • High-Variance Multi-Specification Assembly: US standards (Twin, Full, Queen, King, Cal King), European dimensions, and Japanese profiles require dynamic tooling adjustments for zoned pocket coil springs, memory foam layering, and tape-edge stitching.
  • Strict Chemical & Flame-Retardant Compliance: Stringent standards like US CFR 1633 open-flame flammability compliance require immutable traceability of flame-retardant barrier textiles and latex foam density batches.
  • Shopfloor Observability: Traditional manual batch paper travelers create delays in work-in-progress (WIP) visibility and slow reaction to needle deviation or fabric tension tears.

Sweetnight MES (sn_mes) integrates edge IoT gateways, high-speed machine vision cameras, and sn_plm to establish an automated, self-correcting smart plant.

2. Core Autonomous Capabilities

Agent A: Multi-SKU Mixed-Line Assembly Scheduling

  • Optimizes production sequences across polyurethane foaming stations, pocket coil coilers, and tape-edge sewing machines.
  • Minimizes mechanical changeover idle time by grouping compatible fabric widths, reducing re-tooling downtime by 42% and maximizing Overall Equipment Effectiveness (OEE).

Agent B: Machine Vision Surface & Stitching Defect Triage

  • Deploys 4K industrial vision sensors at taping and roll-packing inspection stages.
  • Edge models detect skipped stitches, textile discoloration, zipper misalignments, and core indentation defects in under 50 milliseconds.
  • Triggers automatic line calibration pauses when consecutive defects appear and posts rich diagnostics directly to the shopfloor supervisor’s Feishu mobile terminal.

Agent C: CFR 1633 Flammability & Lifetime BOM Serial Tracking

  • Imprints a cryptographic QR/RFID identifier into every mattress law label.
  • Binds serial numbers to the exact textile mill batch, latex vulcanization certificate, steel coil heat number, and station operator ID.
  • Enables instant reverse tracing from a consumer warranty claim back to raw material suppliers within 3 seconds.

3. Enterprise ERP & Logistics Feedback Loop

The MES system integrates directly with Sweetnight’s enterprise ecosystem:

  • ERP Integration (sn_erp): Posts finished goods receipts and raw material consumption transactions into SAP / Kingdee ERP in real time, supporting precise standard costing and inventory valuation.
  • SCM Control Tower Linkage (sn_scm_tower): Finished pallet scans immediately update ocean container packing schedules, triggering export booking confirmations.
