Sapient Automation has redesigned its Viper vertical lift module (VLM) to include an automatic tray-height scanning system and improved storage trays. These improvements can provide greater storage density in a much smaller footprint, says the manufacturer. According to Sapient, its scanning system and tray design can improve the module's storage density by 50 percent or higher.
The VLM's automatic tray-height scanning system verifies the exact height of each tray as well as that of the product. The system calculates best tray height for each item in storage and determines the optimal storage position based on optimizing both space and retrieval time.
Storage capacity has also been increased by redesigning trays to have thinner side walls, flat bottoms, and no dividers or cross-members. The trays are available in 2-, 3-, and 4-meter widths.
