iF Design Award for Modular Long-Stroke Grippers
15.12.2010 -
The PHL from SCHUNK outperformes in efficiency and design
The newly developed PHL long-stroke gripper from SCHUNK combines in a unique manner, technological know-how and functional, appealing design. As one of the first long-stroke gripper ever, it optionally disposes of a multi-tooth guidance or a profiled rail guidance, which considerably increases the module’s degree of efficiency. For this successful symbiosis, the gripper was recently awarded with the iF Product Design Award 2011.
The PHL in modular design from SCHUNK, the competence leader in clamping technology and gripping systems is offered in 90 standardized versions. The design of every version remains unchanged, and thus a high recognition value of the gripper is assured. With the PHL over-sizing can be avoided, the consumption of compressed air and energy are minimized, and the required space of applications is reduced. Efficient gripping of large strokes is also possible.
Compact powerhouses reduce costs
Within the design concept from this innovative family-owned company, light-weight design aspects were considered, and the functional aspects of a modular system. With jaw guides and a powerful multi-tooth guidance, the PHL is particularly suitable for rough environments. It is equipped with roller bearings and profiled rail guidance, achieving a 25 % higher degree of efficiency. The guide carriage of the gripper fingers are ball seated, minimizing friction and assures an optimum power distribution. Due to the closed, permanently lubricated linear roller guide, the payload capacity of the gripper increases and wear reduced. Users benefit from the permanently reliable precision and a long lifetime of the component. With the PHL SCHUNK blurred the boarders between standardized and individual solutions. Length and stroke of the PHL can be individually defined. The individual solution becomes standardized at an ideal price-performance ratio.
The new gripper generation from SCHUNK clearly exceeds the performance of conventional long-stroke grippers with T-slots or round guidance. For many applications smaller, low-priced gripper sizes will meet the requirements now, which have a lower compressed air consumption and therefore are more efficient. Alternatively, longer fingers can be used at an approximately identical gripping force. With its long stroke, the PHL is suitable for handling large components, as well as for batch production, where various workpiece sizes are manufactured on one single processing line. Components with large undercuts can be gripped safely, too.
Modular concept allows enormous diversity of variants
For grippers with the multi-tooth guidance, or the profiled rail guidance, five sizes with piston diameters between 25 and 63 mm are available. The user may choose between three strokes per size, so that every stroke between 30 and 160 mm is covered. Moreover, the gripper can be equipped with springs for gripping force maintenance for I.D. and O.D. gripping. All in all 90 standardized versions are available. The largest size of the PHL provides a gripping force of 3500 N, and a maximum admissible finger length of 600 mm. On option for every size, a version with special viton seals or a high-temperature version for hot environments of up to 130 °C is available. The gripper position can be monitored via inductive proximity switches, or via magnetic switches. For this purpose, the gripper is already equipped with an integrated sensor groove.
