Detailed Information
Technology Overview
The LOGIMAT Vertical Lift Module (VLM) by SSI SCHAEFER is a fully automated storage and retrieval system (ASRS) designed to provide an effective alternative to larger, more complex ASRS solutions. Its core differentiating feature is the internal rack and pinion drive mechanism, which ensures precise and reliable movement. This technology consolidates storage into a compact vertical footprint while simultaneously serving as an integrated picking workstation. It is positioned as a user-friendly automation solution that can be adapted to a wide range of warehouse and production environments to simplify operations and maximize space.
How It Works
Core Principles
The system operates on the "goods-to-person" principle. Inventory is stored in trays within a vertical column structure. An automated extraction mechanism, powered by a rack and pinion drive system, retrieves the required tray and delivers it directly to an ergonomic workstation for the operator.
Key Features & Capabilities
The Rack and Pinion Drive System is a standout feature that provides robust, precise, and smooth movement for the extractor, contributing to system longevity and reliability. The Space Condensing Capability allows the VLM to store a vast number of items in a minimal floor footprint by utilizing vertical space, effectively freeing up valuable floor area. Its role as an Innovative Picking Solution transforms the unit from pure storage into an active ergonomic workstation that brings items to the operator, streamlining the order fulfillment process.
Advantages & Benefits
A primary benefit is its operational effectiveness, which can rival larger ASRS systems in appropriate applications, offering a high level of automation in a more compact form factor. The system is designed to make jobs easier by reducing walking, searching, and manual handling for operators, leading to increased productivity and reduced errors. Furthermore, its ease of use and flexible integration means it can be deployed as a standalone solution or networked across a facility without requiring extensive modifications to the existing layout.
Implementation Considerations
Implementing a LOGIMAT VLM requires assessing the facility's ceiling height and floor space to accommodate the unit's dimensions. While easier to integrate than some large-scale ASRS, it still involves a significant capital investment that must be justified by gains in space utilization, labor efficiency, and accuracy. The system's flexibility is an advantage for fitting into existing operations.
Use Cases & Applications
Ideal For
This solution is ideal for operations needing to maximize storage density, improve picking ergonomics and speed, and implement automation without the footprint or complexity of a large ASRS.
Conclusion
The SSI SCHAEFER LOGIMAT Vertical Lift Module presents a compelling and effective automated storage solution. Its unique rack and pinion drive offers reliability, while its compact, goods-to-person design delivers significant benefits in space savings, operational efficiency, and worker ergonomics. For facilities looking to implement a scalable and user-friendly ASRS that can fit into existing spaces, the LOGIMAT VLM is a strong candidate to streamline storage and picking processes.
