Tightening automation With the efficiency of pick and place. Automatic screw presenters Screw suction systems • For automatic and manual use

Tightening systems with automati for very fast and efficient tighteni When carrying out manual assembly with small screws on the bench or an automatic assembly line, tightening time is essential to increase productivity. These automatic screw feed systems significantly reduce cycle times and can be used in both manual pick-and-place and automatic processes. In fact the screws can be picked up easily by a magnetic bit or by a screw suction system, ready for immediate tightening. The models offered provide a flexible solution to most application situations that can arise in normal industrial...

Manual pick-and-place systems • For magnetisable screws with PHILLIPS or POZIDRIV recesses and lengths up to 18 mm • For straight air and electric screwdrivers with lever start The pick-and-place systems for manual use consist of NJ screw presenters to ensure fast, smooth work cycles, helping to reduce production costs. The benefits: • No manual steps: operators do not have to pick up screws manually and place them on the screwdriver bit, reducing cycle times by over 24%. • Very convenient to use: just pick the screw in the pick-up “well” from the selection channel with the screwdriver,...

Manual and automatic pick-and-place systems • For screws made of any material, even non-magnetisable with lengths up to 18 mm • For all recess types • For screwdrivers with screw suction systems • For nutrunner motors with screw suction systems and that are installed on slides or robots NJR screw presenters are very versatile because the screw suction system with which the coupled tools must be equipped means they can be used in a multitude of manual and automatic applications. The benefits: • They can be used with any screw type, including those with Torx or hexagonal recesses: the screw...
