PIONEERING FEATURES:

1.GRIPPERS with INTEGRATED VACUUM TECHNOLOGY

The ejector pumps have become so small that they can be placed straight at the very place of suction in so-called integrated vacuum grippers. These increase the speed of the system by minimizing the amount of air that must be evacuated. Adaptation to the application is thus simplified by the use of the small and lightweight vacuum grippers.

2. Innovative materials in SUCTION CUPS

The material properties of the suction cups are crucial for the function. We can create perfectly adapted suction cups when it comes to pliability, durability and chemical resistance. Thanks to the built-in filter the vacuum system is also protected against foreign particles, which is of great importance to the cost of maintenance.

3. Hands-off BULK HANDLING with vacuum conveying.

Powder materials are common in chemical industries and similar industries such as the food and pharmaceutical industries. Vacuum conveying is an unsurpassed means of satisfying the demanding requirements of cleanliness and hygiene.

PIAB SUCTION CUPS |

Using suction cups is a lifting technique with many possibilities. You can, for example, handle board materials or concrete slabs, open bags, pick electronic components, label and hold objects. But different applications need different requirements. PIAB offers one of the market’s widest ranges of suction cups so that each application will have its own solution.

Suction cups made from DURAFLEX ® — for increased productivity and performance

Increase your productivity and security with DURAFLEX ®, a strong and elastic material with excellent sealing capability. High friction and reduced micro-leakage increase the lifting capability and the cup’s outstanding wear resistance extends the change-over intervals. PIAB’s unique dual-hardness cups are ideally suited for applications where micro-leakage can occur, for example when a suction cup does not properly conform to a handled material, such as corrugated cardboard. Dual-hardness cups provide both the strength and flexibility needed to seal on uneven or coarse surfaces.

| SUCTION CUP MODELS |

Every application requires a particular design of suction cup. The Models described here will cover virtually any need.

MODELS: D20-2, DF80P, D15-2, D30-2, D50, DF80P
SUCTION CUP WITH VALVE
When several cups are connected together in a single system, for example in a lifting device, the system can be adversely affected if a suction cup leaks or misses the work-piece. To overcome this, each suction cup can be provided with a valve that opens only when the suction cup is in contact with the object. The advantages are increased safety, less air consumption and faster action.
FC – FLAT, CONCAVE SUCTION CUP WITH INTERNAL CLEATS
Designed for flat and slightly curved surfaces. A typical application is the feeding of sheet metal into a press tool. The slightly curved shape and internal cleats provide a good grip and the strengthened lip extends the life of the cup considerably.

GENERAL OPERATING PRINCIPLES OF SUCTION CUPS

How does a suction cup work?

 

A suction cup adheres to a surface when the surrounding pressure (atmospheric pressure) is higher than the pressure between the suction cup and the surface of the object. To create the low pressure in the suction cup it is connected to a vacuum source. The lower the pressure, the higher the vacuum in the suction cup — results in increased lifting force.

Energy Requirements

Suction cups should not be exposed to unnecessarily high vacuum levels. Too high vacuum levels will cause unnecessary wear and require more energy. With an increase of the vacuum level from 18 -inHg to 27 -inHg the lifting force increases by 20–40% while the energy requirements are increased by a factor of 10.
Since the lifting force is directly proportional to the area of the suction cup, it is better to maintain a lower vacuum level and increase the area of the suction cup when more lifting force is required.

Safety Factors

The lifting force can be perpendicular or parallel to the surface to be handled. The values are based on sample data for a dry steel plate.
When sizing a suction cup, we recommend to always multiply the weight of the object to be handled by a minimum factor of 2 for increased safety.

Acceleration and Deceleration

Rapidly moving objects have additional dynamic forces arising from acceleration and deceleration. In this case, we recommend multiplying the object's weight by a minimum of 2.5 when calculating the size of the suction cup.

Savings in energy and system costs

Leakage occurs in a system when one or more suction cups do not contact the object being handled. This may happen in applications where the number, the position or the size of the objects to be lifted varies. Usually a large vacuum pump is used to cope with the air leakage and to maintain the vacuum level. The result is an inefficient system in terms of energy and capital costs.
A better solution is to use PIAB fittings with valves. The valves stop or reduce the leakage so that a smaller, more appropriate vacuum pump can be used to decrease installation and operation costs.

Dual Control Valve

The air evacuated by the vacuum pump can only flow through a small opening (restriction). Even if the suction cup does not make contact with the object, the leakage will be minimal and the system will not be affected to any significant degree (a). When the suction cup makes contact with the object, only the cup’s own volume has to be evacuated and the vacuum is created rapidly (b). When the object is released, air opens the built-in flap valve in the fitting and flows through a larger opening. The object is thus released very quickly (c).
Caution: Fittings with dual flow control valves can be assembled on suction cups from 20 to 50mm in size (0.79"-1.97" dia.). They are used only when lifting objects made of non-porous material.

Choosing the Right PUMP

How to choose the right PIAB vacuum pump when using a fitting with dual flow control valve.

The pump should be able to cope with the maximum leakage flow or the induced air that flows through the restriction. The following table shows, for every suction cup size, the diameter of the restriction and the air flow. The flow calculation is for a system with one suction cup and a vacuum level of 11.8 to 29.4 -inHg.

VACUUM PUMPS | WITH COAX® TECHNOLOGY |

PIAB's new COAX is the latest patented technology is an offshoot of the multi-stage ejector principle.
COAX® ensures excellent performance at both low and high feed pressures. It’s ideal for situations where compressed air lines deliver air at low or fluctuating pressures.
Pumps based on the COAX® technology can operate within the range of 25 to 87 psi.

Principle behind the COAX® technology

PIAB pioneered and engineered the multistage ejector pump from the simple, single stage pump where suction is induced by a compressed air flow through a Lavel Tube.



Multi-stage ejector

PIAB vacuum pumps are of the multi-stage ejector type –a technology patented by PIAB in 1973.
These vacuum pumps were developed to provide extra vacuum flow in combination with deep maximum vacuum levels while keeping energy consumption at a minimum.

P3010 is based on this new technology, derived from the multi-stage ejector principle. Note that both a filter and check valves are integrated into the ejector section. When compressed air (red) passes through the nozzles, air is pulled through with the stream of compressed air. “Suction” (blue) is thus created at the opening of each stage.

Other PIAB designs incorporating COAX ® technology include the Vacuum Gripper System, P2010, P6010, PMAT, Vacustat and the Adjustable Vacuum Palletizer.

PIAB vacuum pumps are compressed air-driven vacuum pumps. The unique construction makes maximum use of the compressed air and therefore consumes less energy. Large vacuum flows and high levels of vacuum are characteristic of PIAB’s vacuum pumps.
When compressed air (1) passes through the nozzles, air is pulled through (2) with the stream of compressed air. “Suction” (3,4,) is thus created at the opening of each stage, resulting in low pressure, vacuum.

Advantages of PIAB Vacuum Pumps based on COAX Technology

PIAB pumps have no moving parts that vibrate or wear out – important features that contribute heavily to outstanding operational reliability and a pleasant, noise-free working environment.

Vacustat COAX®

PIAB introduces a market-unique decentralized vacuum pump for sealed applications. The pump is equipped with an integrated air-saving function and a COAX® cartridge Mini Pi12-2. The pump also contains a built-in check valve on a blow-off port.

Customer benefits

The Vacustat-COAX® unit is the “ultimate” energy-saving solution for handling sealed objects with suction cups. Since the position of the pump will be right at the suction cup, the risk for micro leakage in fittings and hoses are considerably reduced in comparison to a centralized ES system, such as an AVM™ or a Classic ES system. The small volume that is necessary to evacuate (just the cup) means that the air-saving mode will be reached almost instantly.

Energy savings compared to systems without ES (energy saving) function can be up to 99%, depending on the cycle time. Compared to a centralised ES system the decentralized Vacustat-COAX® solution can save up to 50-80% in air consumption.

PRINCIPLE OF VACUUM CONVEYING

  1. Vacuum is generated by a compressed air-driven PIAB vacuum pump A. The pump can easily be controlled automatically. Since it has few moving parts, the pump is virtually maintenance-free.
  2. The bottom valve B is closed, and vacuum is raised in the container C and the conveying pipeline D.
  3. From the feed station E the material is drawn into the conveying pipeline and then on to the container.
  4. The filter F prevents dust and fine particles from being drawn into the pump and escaping into the surroundings.
  5. During the suction period, the air shock tanks G are filled with compressed air.
  6. When the material container is full, the vacuum pump is stopped. The bottom valve opens and the material in the container is discharged. At the same time, the compressed air in the filter tank is released and cleans the filter
  7. When the pump is restarted, the process is repeated and a new cycle begins. The suction and discharge times are normally controlled by pneumatic or electrical control systems H
