Goods-to-Person Carousel System

The AS-RS Vertical/Horizontal Carousel System engineered by gdasrs.com integrates automated mechanical rotation with ergonomic pick-face presentation. Designed for high-density storage of small-to-medium components, the system indexes shelves via a closed-loop chain or belt drive directly to an operator access opening. This configuration eliminates horizontal travel and vertical climbing, raising pick rates to 300–500 lines per operator hour while reclaiming up to 70% of traditional floor space.

Structural Frame: Cold-formed high-tensile structural steel profiles (Q355B), laser-cut and robot-welded to maintain vertical alignment tolerances under full load.
Drive Mechanism: Direct-coupled helical-bevel gear motors paired with absolute optical encoders for closed-loop positioning feedback.
Carrier Assembly: Folded galvanized steel shelves with bolted partitions, engineered to resist deflection under maximum rated load.
Access Opening: Ergonomic work counter featuring integrated pick-to-light LED bars and physical safety light curtains complying with ISO 13849-1.

Command Execution: The local industrial PC receives an order line item from the host WMS.
Path Optimization: The controller calculates the shortest rotational path (bi-directional shortest route algorithm) to minimize retrieval cycle time.
Drive Engagement: The VFD motor drives the continuous loop chain, bringing the target carrier to the access window.
Operator Interaction: The access window shutter opens automatically. Pick-to-light guidance highlights the exact bin location and pick quantity.
Confirmation: The operator confirms the pick via a physical push-button or optical sensor, and the system logs the inventory decrement in real-time.

Footprint Optimization: Replaces up to 600 square meters of traditional static shelving with a single vertical footprint.
Dynamic Height Adjustment: Internal optical sensors measure incoming stored goods profile height during loading, dynamically adjusting vertical pitch spacing to eliminate wasted vertical gaps.
Multi-Depth Storage: Supports single-deep and dual-deep configurations based on SKU velocity and turnover frequency.

Throughput: Average single-cycle retrieval time under 35 seconds.
Positioning Accuracy: Carrier leveling precision within $\pm1.0\text{ mm}$ verified by magnetic limit switches and encoder feedback.
Acoustic Emission: Operating noise level does not exceed 65 dB(A) measured at 1 meter distance under full load.
Duty Cycle: Rated for continuous 24/7 industrial operation cycles.

Control Architecture: Siemens S7-1200 / 1500 PLC paired with an industrial touch-panel HMI (15-inch IP65 rated).
Safety Interlocks: Dual-channel safety relays, mechanical anti-fall drop brakes, and emergency stop circuits integrated directly into the drive inverter.
Diagnostics: Real-time motor temperature monitoring, current overload protection, and error code logging displayed on the HMI interface.

Communication Protocols: TCP/IP, RESTful API, OPC UA, and standard ASCII file exchange.
Host Compatibility: Native drivers for SAP EWM, Oracle WMS, Manhattan Associates, and proprietary SQL-based ERP databases.
Inventory Management: Real-time stock tracking, ABC analysis categorization, and automated cycle counting routines without halting system operations.

Structural Customization: Tailored access window heights, dual-side loading ports (front and rear access), and cleanroom-compliant powder coating or stainless-steel cladding (SUS304).
Environmental Adaptability: Low-temperature operating packages available for cold storage facilities down to $-25^\circ\text{C}$.
Installation Procedure: Modular bolt-together assembly completed by certified mechanical engineers, minimizing on-site welding and downtime.

Electronics Manufacturing: ESD-safe grounded shelving for component storage and PCB magazine buffering.
Automotive Aftermarket: High-density storage for irregular spare parts, gaskets, and heavy fasteners.
Pharmaceutical & Medical: Secure, temperature-monitored storage for regulated medical devices and clinical supplies.
Aerospace Maintenance: Traceable tool crib management and high-load component kitting.

Certifications: CE (Machinery Directive 2006/42/EC), ISO 9001 quality management manufacturing standards, and UL-certified electrical control panels.
