Circular flat and bellow Maxigrip Vacuum Cups

Circular flat and bellow Maxigrip Vacuum Cups

These vacuum cups have been created as an alternative to the ordinary cups used in the robot-automotive field and they offer an excellent solution to gripping and handling problems that could arise on vacuum-driven handlers in every industry sector. They can be both flat and bellow-type, round and oval and equipped with support. The extremely flexible outside lip, can be associated with the typical features of the bellow cups, allow them to adapt themselves on flat, concave and convex surfaces with no risk of deforming or breaking even the thinnest objects to be handled. The innovative design of the inside of the cups, which facilitates the drainage of oil and water, ensures a high friction coefficient with the gripping surface and, in particular, a unique grip on oil-covered metal sheets or wet glass or marble sheets. This particular feature guarantees a firm grip and, therefore, an accurate placemet of the load to be handled. The MAXIGRIP standard vacuum cups are made with our exclusive BENZ compound:
- Hardness 60÷75°Sh.
- Working temperature between -40 and +170 °C
- Stain-resistant
- Excellent resistance to abrasion, water and to oils containing chlorine.
Their galvanised steel support is vulcanised onto the cup. A wide range of accessories, such as adapters, couplers and articulated joints, allows them to be installed on any vacuum-driven handler. Because of their universality of use, these cups can also be provided in the special compounds shown on top.

Special built-in Vacuum Cups with ball valve

Special built-in Vacuum Cups with ball valve

The main feature of the special built-in cups is that they open, and therefore produce vacuum, only when the load to be clamped activates the sealing ball. Especially designed for the vacuum operated beds of woodworking machines, they differ from the previously described ones because of the high precision of their cylindrical support, which is ground to size, and because of their square closing block, which prevents the cup from rotating and enables connection to vacuum. The cold-assembled cups are the flat ones listed in the table in the various compounds. Their support is made with anodised aluminium, while the closing block is made with brass.

Vacuum Cups based on Bernoulli’s theorem

Vacuum Cups based on Bernoulli’s theorem

Bernoulli’s theorem explains many phenomena, such as the lifting of a plane’s wing or of a light disc in front of a tube end from which air flows out quickly. This apparently paradoxical phenomenon is exploited for manufacturing vacuum gripping systems (vacuum cups) and handling, with no contact, fragile objects, such as semiconductor plates, silica discs, solar cells, precious metal foils, films and whatever needs to be handled with the greatest care. Our cups based on Bernoulli’s principle are made with anodised aluminium, with stainless steel centre thrust disc. The antistatic silicon spacers, located on the cup gripping plane, prevent transverse movements of the gripped object. The compressed air supply connections can be axial and radial and the quick coupler for the flexible pipe is included in the package. The unused holes are closed with brass threaded caps. On the rear part of the cup there are 3 or 4 threaded holes for fiving it to the machine.

Special cup holders with plunger valve

Special cup holders with plunger valve

These cup holders share the same technical features as the other basic cup holders.
Their distinctive feature is the plunger valve solidly connected to a conical valve, which activates the suction, thus creating vacuum, only when the cups come into contact with the load to be lifted.
With these cup holders it is no longer necessary to install cocks on the suction hoses; for this reason, they are recommended in all those cases in which there is a chance that not all the cups come into contact with the load to be lifted (because of an uneven or incomplete load).
The actual springing stroke is:
- For height C= 55 mm 37 mm
- For height C= 110 mm 84 mm

Special cup holders with push valve

Special cup holders with push valve

The distinctive feature of these cup holders is the push valve on the cup support, which activates suction, and therefore creates vacuum, only when the cup is in contact with the load to be lifted.
With these cup holders it is no longer necessary to install cocks on the suction hoses; for this reason, they are recommended in all those cases in which there is a chance that not all the cups come into contact with the load to be lifted (because of an uneven or incomplete load).
The same push valve can also be applied with no modification to the special articulated cup holders.
The actual springing stroke is:
- For height C= 55 mm 37 mm
- For height C= 110 mm 84 mm

Multi-stage, multi-function and modular intermediate vacuum modules series mi – general information

Multi-stage, multi-function and modular intermediate vacuum modules series mi – general information

Intermediate modules are non-independent multi-stage and multi-function vacuum generators to be assembled to the generators of the GVMM range. Their thickness and weight are reduced to the maximum compared to their suction capacity and they have been designed to be enclosed between the lid and the base of the GVMM vacuum generator and fixed with screws. The internal connections for the compressed air supply allow communication between them and the basic generator, with no need for external manifolds. This way, each module becomes an independent vacuum unit that can control an entire vacuum system. They can be ordered in the desired amount and capacity, either already assembled onto the GVMM multi-function vacuum generator, or separately, to be assembled to the GVMM generator previously installed onto the machine. In this case, we suggest ordering a screw kit suitable for the number of modules to be assembled. MI intermediate vacuum modules are made up of the same elements that compose GVMM generators, except for the lid. They operate and they are used as the GVMM multi-function vacuum generator onto which they are assembled.

Electric equipment for vacuum test

Electric equipment for vacuum test

These devices have been created for testing the weldings and, therefore, the sealing of cellophane or PVC wrappings for food products.
In fact, the wrapping placed inside a bell jar tends to inflate because of the pressure differential created between the air at atmospheric pressure contained inside and the vacuum created inside the bell jar. The higher the vacuum level reached in the bell jar and the greater the thrust that the air contained in the wrapping will exert on the walls and, therefore, on the weldings.
The devices for vacuum tests are composed of:
- A mobile transparent plexiglas bell jar.
- A support surface with seal.
- A dry rotating vane vacuum pump.
- Two 2-way manual valves for vacuum interception.
- A vacuum gauge for a direct reading of the vacuum level.
- A mini vacuum switch for vacuum level adjustment.
- A switchgear enclosed in a special protective casing.
- A bent sheet steel frame with anti-vibration feet for assembling all the components.
The vacuum level that can be reached inside the bell jar depends on the pump installed.
The test values are adjustable and can be automatically repeated. They can be supplied in different versions upon request.

Pneumatic equipment for vacuum test

Pneumatic equipment for vacuum test

The function of these devices is to test the welding sealing in flow-pack, cellophane or food product wrappings. They are composed of:
- A transparent plexiglass cylindrical container into which the water is poured and the vacuum is created.
- A mobile transparent plexiglass lid with, on its lower part, a perforated disc fixed via a pin which is for keeping the flow-pack wrapping submerged in the water, in the container and on its upper part, the instruments for managing and controlling the vacuum.
- A multiple ejector multi-stage vacuum generator.
- A check valve located on the generator suction inlet to prevent the air from returning into the container when the generator is not in operation.
- A sleeve valve for compressed air interception.
- A supply compressed air reducer equipped with pressure gauge.
- A 2-way manual valve for restoring the atmospheric pressure inside the container.
The wrapping submerged in the water in the container tends to inflate because of the pressure differential produced between the air at atmospheric pressure on its inside and the vacuum created in the container. The higher the vacuum level reached in the bell jar and the greater the thrust that the air contained in the wrapping will exert on the walls and, therefore, on the weldings. Any air leak from the wrapping due to a defecting welding is proved by bubbles that indicate the exact point of the welding that’s leaking. The vacuum level that can be reached inside the bell jar depends on the pump installed. The test values are adjustable and can be automatically repeated. They can be supplied in different versions upon request.
