Coil-Hover automates coil handling after slitting process
hpl-Neugnadenfelder Maschinenfabrik presents the new handling system “Coil-Hover” for the first time at the upcoming Metec 2015 in Dusseldorf, Germany. It simplifies and accelerates the handling of split rings. Since only a vacuum or magnetic forces are applied to the split rings, their transport from the turnstile to the storage area bears practically no risk of damage to the material. The largely automated operation reduces personnel costs: only one person operates the complete machine.
The Coil-Hover largely automates the separation of coils and their take over from the turnstile as well as their tilting, strapping and further transport to the storage area. The core of this new system is a swiveling table on slides, superseding the use of a commonly used crane. The Coil-Hover avoids any damages of the strip edges or surface, because the coils do not get in contact with a crane hook and do not run on rollers.
The system is designed to handle coils with an outer diameter of up to 2,000 mm and a width of up to 300 mm. It can be used for almost any kind of ferrous and non-ferrous metals. Ferromagnetic strips are held on the swiveling table by electro permanent magnets.
For handling non-ferromagnetic strips, the swiveling table is equipped with an aluminum suction plate with several suction rings holding the split ring securely in place.
Thomas Pieper, sales manager at hpl, declares the extraordinary name: “The new system is named Coil-Hover, because all the way to the strapping tables and storage area the coils are indeed hanging under the swiveling table – just like the Wuppertal suspension railway under its supporting frame. Furthermore, their transport from one station to another bears practically no risk of damage to the material – they seem to be floating.”
After being taken from the turnstile, the split rings are turned down by 90° by means of hydraulic cylinders. The coil is “floating” under the swiveling table in this position – only held in place by a vacuum or the magnet.
The coil is positioned on the strapping table. After being strapped, it is taken up from the Coil-Hover and placed on a lift table which is then leaving the line area – the Coil-Hover is ready to handle the next split ring. Up to 60 split rings per hour can be handled using the version with two Coil-Hovers and two strapping tables.
