Screw Presenter

The Cost-Effective Entry Point to Production Automation Looking for a quick, affordable way to automate your assembly process—but a fully automatic screw feeder isn’t practical due to low screw volumes? The DEPRAG Screw Presenter and Screw Dispenser offer the perfect solution. The Screw Presenter automatically positions each screw for pickup by a handheld or stationary screwdriver, streamlining manual assembly with minimal investment. In contrast, the Screw Dispenser provides screws for manual removal, offering simple yet reliable support for low-volume operations. Designed for screws with a shaft diameter of 1.4–5 mm and a maximum shaft length of 18 mm, this system is especially well-suited for countersunk screws, ensuring smooth, precise handling every time. How the Screw Presenter Works A screw separator sorts and positions each individual screw for pickup. The operator removes the screw with an upward motion for efficient handling. A signal output enables the host controller to monitor and manage the pickup position for seamless process integration. With DEPRAG’s Screw Presenter and Screw Dispenser, you gain a cost-effective, flexible introduction to automation, enhancing productivity without the complexity of a full feeding system.

Screw Dispenser

The DEPRAG Screw Dispenser is designed and optimized for use in manual workstations, ensuring efficient and reliable screw supply. It accommodates screws with a maximum head diameter of 12 mm and lengths of up to 30 mm (small version) or 60 mm (large version). How It Works Screws are automatically delivered from the feeding system into the dispenser container. When the operator reaches into the extraction area, an optical sensor detects the hand and activates the slide opening, allowing screws to fall conveniently into the operator’s hand. Key Advantages Reliable Processing – Supplies the correct number and type of screws, minimizing errors and improving process reliability. Flexible Integration – Can be combined with various DEPRAG feeding devices to deliver up to three different screw types.

Mini Screw Feeder

The DEPRAG Mini Screw Feeder is specifically designed for the precise feeding of very small, rotationally symmetrical components, such as micro and mini screws. A rotating disk mechanism positions each fastener individually, delivering it to a defined pickup point for reliable retrieval via magnet or vacuum. This ensures accurate, consistent, and gentle part handling—ideal for miniature assemblies. Versatile in application, the Mini Screw Feeder can be seamlessly integrated into both manual workstations and fully automated production systems, providing maximum flexibility and efficiency in micro-assembly operations.

Eacy Step Feeder System

The eacy step feed system delivers exceptionally gentle, precise handling of feed materials. Unlike traditional systems, vibration is confined to the linear feed rails, minimizing stress on components and ensuring smooth operation. Driven by a brushless electric motor and controlled by the intelligent, energy-efficient PFC100 controller, the system provides precise speed regulation for careful, low-friction part feeding. This design minimizes particle build-up, ensuring maximum cleanliness and reliability. For applications with stricter cleanliness requirements, optional vacuum suction equipment can be integrated. The system also supports the DEPRAG CleanFeed concept, which prevents, reduces, and removes abrasion throughout every stage—from part feeding to fastening. The eacy step feed can be seamlessly combined with DEPRAG storage systems, maintaining consistent fill volumes and extending reloading intervals. It’s also fully compatible with other DEPRAG automation components, including the Feed Module DFM, screwdriving function modules, and the DCOS Controller System. With its high feed rate, long service life, and compact footprint, particularly for longer feed parts, the eacy step feed offers a superior alternative to traditional vibratory spiral or sword feeders—delivering clean, quiet, and efficient part feeding for modern production environments.

Sword Feeder System

Sword (segment) feeders offer an excellent alternative to traditional vibratory feeders when gentle, low-wear part handling is essential. Available in two sizes—with 0.15-liter or 1.5-liter fill volumes—they ensure efficient, reliable feeding even for delicate or sensitive components. Precise part positioning is achieved through the intelligent design of the segment-shaped feed rail, which lifts components from the reservoir using a smooth, swinging motion. Guided by gravity and mechanical deflectors, parts glide carefully to the feed rail in the correct orientation. Any misaligned components are automatically redirected back into the reservoir, ensuring a consistent, position-accurate feed with minimal wear and maximum efficiency.
