Step conveyors from WEBER move fasteners very gently and with low noise. WEBER has now added the powerful ZEL480 variant to its successful product line
Wolfratshausen – With the ZEL480 model, WEBER Schraubautomaten GmbH presents an especially powerful and robust variant of its step conveyors. The new ZEL480 variant is suitable in particular for processing large fasteners and components, while offering customers the same benefits as the existing ZEL240 and ZEL360 designs.
The ZEL480 step conveyor is now available and can be used for automatically feeding screws with a head diameter of up to 32 mm, a shaft diameter of up to 16 mm and a shaft length of up to 120 mm – a 40 percent increase in the maximum possible component size compared to the smaller ZEL360.
The demand for larger automatic feed system has arisen in recent years in particular in the automotive industry. The expanding e-mobility market and the consequently growing number of installed batteries have generated substantial demand for systems such as the ZEL480. Battery packs in particular are usually mounted with larger fasteners. This is an essential area of application for the ZEL480.
Gentle on the material and low noise
Step conveyors are regarded as a particularly gentle and low noise technology for feeding screws, nuts, caps or special-purpose parts. These product benefits are also implemented by the larger version ZEL480.
The aligned parts are moved towards the escapement unit with gentle vibrations, separated and provided to the tool (e.g. screwdriver) through the feed hose.
The minimized vibrations of the fasteners or components allow for processing of surface-coated and sensitive parts – an essential advantage for complying with standards on technical cleanliness and consequently the best possible process reliability when mounting sensitive workpieces.
At the same time, the technology of the ZEL480 ensures that moving masses are reduced to significantly prevent noise emissions. In addition, WEBER offers a sound enclosure cover for the ZEL480 which further reduces noise generation.
Franz Kroll, Team Leader for Mechanical Design and Development: “The benefits for our customers are evident. The ZEL480 stands out on account of the low abrasion on the components, the very low noise generation and the high output rates. In addition, we use the maximum number of standardized components for the ZEL480 in order to achieve maximum flexibility with short changeover times for feeding components.”
The ZEL480 can be linked to any Weber screw system. Very large fasteners and components can be accepted from the escapement unit of the ZEL480 step conveyor and moved to the screwdriving location with a pick & place solution.
