Schunk shows new IO-Link gripper at EMO

170721_SchunkAt the forthcoming EMO exhibition, Schunk will be further expanding its flagship PGN-plus gripper brand with the arrival of the PGN-plus-E with an IO-link. The competence leader for gripping systems and clamping technology will be presenting the world’s first lifelong maintenance-free 24V premium electric gripper, which completely fulfils the IO-link class B standard at EMO, on booth E55 in Hall 3.

The new arrival only requires one connection plug to control the gripper, parameterise and to use the integrated diagnostics function. It can be directly connected to the IO-link class B master without a Y distributor. The required control and power electronics are integrated into the compact module, so no space is taken up in the control cabinet. The gripping force can be individually adjusted to the workpiece via the IO-link. This permits handling scenarios with complete flexibility for a wide variety of parts. In order to achieve the shortest closing and cycle times, the gripper fingers can be pre-positioned as desired.

The sensors are integrated as standard and can be used to measure the stroke and speed of the gripper fingers, as well as the power consumption. This eliminates additional costs for external sensors, the wiring effort is reduced and the process reliability increases, since fewer moving and thus wear-resistant cables are used. An integrated diagnostics function permanently monitors the status of the gripper and automatically transmits errors to the higher-level control system. Moreover, system operators can store any maintenance intervals of the system.

The Schunk PGN-plus-E IO-link has a redesigned, robust multi-tooth guidance system that allows higher maximum moments with lubricant pocket through-holes in the multi-tooth guidance, as well as a diagonal pull kinematics with a high surface coverage in all stroke positions. A brushless DC servomotor drives the mechatronic universal gripper and this ensures consistently high process stability and a lifelong maintenance-free operation. It can be mounted on two gripper sides and in three screw directions. The gripper seamlessly fits into the pillar of the alternative mechatronic modules from Schunk.

All modules feature 24-V technology. In the meantime, the product range has further expanded and complete handling systems based on 24V technology can be combined from linear axes, rotary modules and grippers. Beside the version with IO-link, the gripper is also available for control via digital I/O.
