EXECUTIVE SUMMARY
Industrial batching and filling operations frequently suffer from closed, proprietary vendor architecture, leaving plants vulnerable to extended downtime when components fail or suppliers exit the market. This case study details how Brechbuhler Scales re-engineered an unserviceable legacy bagging and packaging operation. By implementing custom-fabricated mechanical adjustments alongside a standard, off-the-shelf Programmable Logic Controller (PLC) package, Brechbuhler eliminated custom engineering bottlenecks, mitigated manual transcription errors, and established 100% field service autonomy for the client's internal maintenance team.
THE CHALLENGE: THE HIGH COST OF PROPRIETARY VULNERABILITY
A high-throughput manufacturing facility utilizing industrial chemical bag packaging and rock salt filling frameworks encountered an operational crisis. The existing system relied completely on highly proprietary control hardware and closed-source software supplied by a legacy vendor that subsequently went out of business. This left the client with an unsupported system, severe technical vulnerabilities, and zero recourse for replacing failing electronics.
Compounding the software crisis were two critical engineering flaws:
Buried Service Access: In the legacy rock salt bagging configuration, pneumatic cylinders and material valves were positioned completely blind beneath an integrated product tray. Routine servicing or manual resets required multiple staff members, a complete system shutdown, and exhaustive disassembly labor.
Manual Operator Friction: The existing weight-verification and layer-building steps relied entirely on manual operator intervention and visual confirmation. Human transcription and reading mistakes (e.g., misinterpreting 16 lbs for 17 lbs on local readouts) introduced routine batch variations, costly material waste, and frequent downstream rework.
THE INNOVATION: DECOUPLED SOFTWARE & PRE-WIRED HARDWARE
Brechbuhler Scales engineered a total system migration designed to isolate software database layers from physical hardware functions, using open architecture to eliminate single-source dependencies.
The core solution decoupled data tasks from real-time weight targets. Standard enterprise computers handle software tasks and database recording via Brechbuhler’s ScaleSoft framework. Concurrently, all real-time target weights, vibratory controls, and high-speed valve timings are routed through an isolated, open-source industrial PLC package.
Rather than developing a single-use custom control panel, the Brechbuhler workshop deployed a pre-wired, modular cabinet package. This "cookie-cutter" control configuration fits standard industrial footprints, drastically compressing initial custom engineering layouts and panel fabrication timelines.

THE RESULTS: OPERATIONAL INDEPENDENCE AND ENHANCED THROUGHPUT
The transition from proprietary legacy infrastructure to Brechbuhler’s open-architecture batching and filling environment delivered immediate operational benefits:
Complete Maintenance Autonomy:
Upon project delivery, Brechbuhler provided the client with unrestricted, comprehensive electrical schematics and unlocked PLC program logic. The facility’s internal maintenance crew is now fully empowered to perform 24/7 independent troubleshooting, component replacements, and field software adjustments without waiting for specialized vendor dispatch.
Elimination of Product Rework:
Automated material tracking and direct HMI verification routines completely eliminated manual reading and decimal errors. Batch repeatability achieved consistent targets, bringing product waste down to nominal tolerances.
Enhanced Facility Safety:
By engineering automated weight-layer validations directly on the scissor lift and automating primary material routing, the facility drastically decreased unnecessary secondary forklift handling and cross-dock material transit, materially improving plant floor safety ratings.
