Teaching Grippers to See

SCHUNK has enlarged its number of available sensors for the modular system of grippers with the new OAS sensor. When grippers such as the PGN-plus and the MPG-plus are equipped with an integrated distance and presence sensor, both modules quickly transform into seeing grippers without needing an expensive vision system. The optical system can be directly integrated into the gripping center and continuously supplies the control unit with information, such as measuring the distance of the gripper to the component. This is done during the process without any loss of time. With the OAS, PGN-plus and MPG-plus grippers can differentiate components, recognize position, pick parts from a running belt, detect wrongly gripped components, and increase the reliability of the gripping operation.

The optical sensor works with infrared light at a wavelength of 850 nm. It functions at environmental temperatures between 144 and 1311 F, and fulfills the standards for protection class IP65. The sensor module is multi-functional, and can also be combined with other grippers and automated modules. For example, it can be used for analog position monitoring of long-stroke grippers, by integrating it in one of the two base jaws. Combined with grippers and rotary modules, the sensor can be aligned inwards instead of outwards, which assures piston monitoring.

New VZWF valves for use in closed media circuits by FESTO

The valve VZWF is one of a number of new Festo process solutions that now gives customers a one-stop-shop for Festo high productivity and quality automated systems. Festoos process offerings also include ball, butterfly, and gate valves, and associated automated controls.

Festo introduced the VZWF valve, a force pilot operated solenoid valve that can be used with water, air, and neutral media. This new valves utilize relatively small solenoids to control high pressures with large nominal diameters. The units can switch at pressures as low as 0 bar and close automatically in the case of a pressure loss in the circuit. These valves can be applied in closed media circuits.

The VZWF series is generally suitable for applications in which the medium can be vented downstream of the valve into the atmosphere or a tank. The VZWP is used for gaseous and liquid material flows up to a viscosity of maximum 22 mm2/s. Actuation is supported by the pressure of the medium, a special feature of the VZWF. Smaller coils can be used because of lower power requirements to open the valve the energy of the medium contributes to opening.

Applications for the VZWF valve include: filling systems (secondary circuit), water treatment, pipeline construction, steam boiler construction, liquid gas installations, hot water applications, heating circuits, power plant systems, petrochemical industry, pump systems, storage tank installations, and pneumatic automation systems.

Gas and liquid valve solutions expand Festos process offering that already include lines of ball, butterfly, and gate gas only valves and automated controls, said Craig Correia, process industry segment manager, Festo. Process valves provide OEMs and end users the convenience, quality, and dependability of a one-stop-shop for both discrete and process automation solutions from Festo. And Festo offers a host of online productivity tools that speed up time to market.

High Holding Forces for an Amazing Price.

The Magnetic Gripper EGM from SCHUNK maintains high holding forces even in confined work spaces. It is light-weight, yet powerful enough to handle difficult applications even in situations which may require an emergency stop. It also promotes energy efficiency because electricity is only needed for magnetization and demagnetization of the unit.

This system is able to lift different types of ferrous items (plates, sheets, round bars, pipes, etc.) by using a permanent electro magnetic field. The magnetic action of the product may be activated and deactivated by using a switch or digital input, which automatically alters the product's internal magnetic state.

During the operation phase, when the magnetic force is active, the product is permanently magnetized so that nothing can alter its state except for a demagnetization electrical pulse. For example: When a permanent-electro product is magnetised, it can be held this way indefinatly, even if the power is disconnected and the cables are unplugged. In order to demagnetize it, simply connect the power again and send a demagnetization pulse. This saves electricity and ensures there is no danger of parts being dropped in the event of a power failure.

The EGM can handle alternating between different workpieces with minimal set-up time and without the constricting contours of gripper fingers. Due to the variable number of magnet pole pairs, optimum adaption to individual applications is ensured.

Efficient Gripping of Large Strokes

The PHL from SCHUNK comes in two versions: The pneumatic PHL and the electric EGA.

The standard PHL alternatively has the bearing options of a multi-tooth guidance or a profiled rail guidance, which increases the degree of efficiency of the gripper. For many applications, smaller and more cost-efficient sizes can now be selected. Thus over-sizing is avoided, the air consumption and energy is minimized, and the required space for applications is reduced.

With multi-tooth jaw guidance, the PHL is particularly suitable for rough environments. The gripper can be equipped with roller bearings and profiled rail guidance, achieving a higher degree of efficiency. The carriage for the gripper fingers are equipped with ball bearings, which minimizes friction and evenly distributes forces. Since the jaw guide is sealed and permanently lubricated, the bearing capacity of the gripper increases and reduces wear. Users benefit from the reliability, precision and long service life of the gripper.

The PHL is available in five sizes with piston diameters between 25-63 mm (1-2.5 inch), generating gripping forces up to 3250N (740 lbf). The long stroke ranges up to 320 mm (12.5 inch) of total stroke and the maximum admissible finger length is 500mm (200) which increases the flexibility in design. Every size is available as a special version with Vinton seals for high temperatures of up to 130 C (266 F). Gripper positions can be monitored by inductive proximity switches or magnetic switches.

The electric version of the PHL is the EGA and is the most flexible standard long-stroke gripper on the market. Due to the easy integration of the systemms control unit, all the features can be transferred from the current system onto the module, and offers the advantage of a direct interpolation and control of additional robot axes.

Redundant Valve Manifold from Norgren for Safety Instrumented Systems

SIL certified valve assembly offers unique two out of three protection

A new redundant valve manifold RVM for controlling critical processes brings increased safety and efficiency to Safety Instrumented Systems and other applications where unscheduled shutdowns are unacceptable. The RVM from Norgren is one of the first to offer a two out of three (2oo3) configuration, meaning if one of the three pneumatic logic circuits should malfunction there are two logic circuits still operational, so critical redundancy is maintained.

Norgren, a global supplier of motion and fluid control technologies, has integrated its proven Safety Integrity Level (SIL) certified valves on a single manifold to create the RVM, available in aluminum or stainless steel. The unit eliminates the duplicate piping required to install redundant valve systems. This saves space, simplifies installation and reduces potential leak paths. And, unlike piped systems, the entire valve assembly is SIL approved.

The RVM also features visual indicators of valve position and output status so operators monitoring the equipment can see if they need to schedule service during routine maintenance shutdown. The RVM is also available with a manual or electrical bypass option so valves can be serviced while the assembly remains online. With integral exhaust guards to prevent particle ingress and a temperature range from -55C to 90C, (-67F to 194F) the RVM is an excellent choice for refineries, chemical plants, off-shore rigs or any process where valve malfunction cannot be tolerated.
