Miniload ASRS for spare parts inventory

The Physics of Spare Parts Logistics: Why Static Shelving Fails

In industrial spare parts centers—whether for automotive PCBs, hydraulic valves, or fasteners—SKU proliferation is the enemy. A typical facility might manage 50,000+ unique part numbers. When these are stored in traditional static shelving, you encounter the “Honeycombing Effect.” You are heating, lighting, and paying for air.

More critically, the human cost is unsustainable. An operator walking 12km a day to pick loose parts is not only slow but prone to fatigue-induced errors. Picking the wrong O-ring because of a misread bin label can lead to catastrophic failures in the assembly stage. The としてMiniload / RS solves this by inverting the workflow from “Man-to-Goods” to “Goods-to-Person.”

Structure and Function: Engineered for High-Velocity Picking

The starack-Mini series is designed specifically for tote and carton handling (20kg – 50kg). Unlike heavy pallet stackers, the structural engineering here prioritizes low inertia for extreme acceleration.

• Aluminum Alloy Masts: We utilize lightweight aluminum columns rather than heavy steel for the moving mast. This mass reduction allows the servo motors to achieve accelerations up to 2m/s².
• S-Curve Motion Control: The PLC drives the motors using an S-curve profile, ensuring that delicate electronics or loose parts in open bins do not shift or spill during the rapid 360m/min horizontal travel.
• Energy Regeneration: During deceleration and lowering, the motors act as generators, feeding energy back into the DC bus to power other axes, critical for high-cycle counting operations.

Goods-to-Person (GTP): The Throughput Multiplier

The commercial value of a Miniload system is realized at the workstation. By delivering the exact tote to the operator, we eliminate 100% of the walking time.

For example, in an electronics manufacturing support center, a picker needs to assemble a kit of 50 different components (resistors, capacitors, chips) for a production run. With the starack-Mini, the system sequences the bins. The operator stands at an ergonomic station, and the WMS (Warehouse Management System) directs a laser pointer or Pick-to-Light display to the exact compartment in the tote. This increases picking rates from the industry standard of 60 lines/hour (manual) to over 300 lines/hour (automated).

Accuracy and Integration: The Digital Handshake

Speed is irrelevant if the inventory count is wrong. In spare parts management, inventory accuracy must exceed 99.9%. The starack system acts as the physical execution arm of your WMS/ERP.

When a tote is stored, its coordinates (X, Y, Z) are hard-coded into the database. There is no possibility of a human placing a box of “10mm bolts” in the “12mm bolts” location. Furthermore, for time-sensitive parts like rubber seals or chemical adhesives, the system strictly enforces FIFO (First-In-First-Out) logic, preventing stock obsolescence and waste.

Maximizing Vertical Density

Spare parts are small, but they require massive volume. By utilizing Tote storage automation, we extend storage vertically up to 20 meters. Using Q355 high-strength steel racking with bolt-on connections, we ensure structural rigidity even when storing high-density metal parts. This turns a 2,000 square meter floor footprint into 15,000 square meters of usable storage surface area.
