Schmalz Needle Grippers Lift Things Which Vacuums Cannot Grip
POSTED 06/23/2009
Needle grippers are special grippers which are actuated by compressed air. The needles are driven into the product to be gripped and are withdrawn either by springs or by compressed air. The needles are angled in two different directions in order to ensure secure gripping of the workpiece.
Advantages of needle grippers:
§ Safe handling of flexible materials
§ Various versions for differing operating conditions
§ Various needle diameters and adjustable needle stroke
Typical applications:
Handling of porous and/or flexible materials such as textiles, insulating mats, foams, fibre-compounds such a fleece or felt, carpets, filters, woven materials (e.g. carbon fibres), polystyrene and metal foams.
Available versions
Needle gripper SNG-M
The smallest member of the product range is characterized by its small size and is thus suitable for installation in restricted spaces. The needles are extended by a pulse of compressed air and retracted by springs. The standard version of the needle gripper SNG-M has four needles with a diameter of 0.8 mm, which penetrate the workpiece at an angle of 30°.
Needle gripper SNG-Y
On the needle gripper SNG-Y needles of various diameters can be selected and the needle stroke can be adjusted. This permits the gripper to be configured individually to match its intended use. The needles are extended by a single-acting pneumatic cylinder and retracted by springs. The SNG-Y has 12 needles (with a diameter of 0,8, 1.2 or 2.0 mm) and a penetration angle of 45°.
Needle gripper SNG-D
This version, just like the SNG-Y can be equipped with needles with a diameter of ß.8, 1.2 or 2.0 mm, which means that it can be adapted to match workpieces of varying sizes and shapes. The needles are reliably extended and retracted by a double-acting pneumatic cylinder. The needle gripper SNG-D has 24 needles and a penetration angle of 45°.
