The ACCUBELL® systems developed by Sames allow you to benefit from all the advantages of internal charges when applying water-so-luble paints.

Description

ACCUBELL systems provide an ingenious method for using robotic sprayers with water-based products. High voltage is only applied to the product after loading the paint in an onboard tank electrically insulated from the ground.
• The principle of electrostatic spraying with internal charge and discontinuous filling of a water-based product is exclusively developed and patented by Sames.
• The sprayer connects to a docking filling station between successive painting cycles, where it is rinsed and receives the paint required for the next part.

The solution for the application of two-component water based paints is composed of a standard atomizer ACCUBELLR 708 of 800-cm3 capacity and of an accurate catalyst supply, in order to transport the product up to the static blender built-in into the sprayer-head.

Custumer benefits

• Perfect and flexible application
• Great freedom of parameter setting :
- No relative speed limitations
- Better spraying access and movements, as compared to atomizers with external charges.
• The technology used (rotating bell) allows very fine droplet atomization and good paint spray control. The finish quality meets the most severe coverage and reflection requirements.
• Regular thicknesses, and possibility of applying thick coats in one pass.
• Accurate control of paint flow rate
• Accurate dosing for filling and application (regularity of deposited film).
• Fast response time for changes in setpoints.
• Very short rinsing time, thereby reducing the color changing time (eg, 12 seconds for 100 cc).
• Product isolation
• The robot carries an isolated tank and is therefore never exposed to paint tubes or high voltage cables. This significantly extends system service life and availability.
• Reduced maintenance and operating costs
• No product circuit or high voltage cables in the robot arm and spray booth.
• Direct filling (no manipulation of replacement tank).
• Quick disconnection of the atomizer or of the turbine with bell cup.
• No need for flow rate measurements with calibrated sampling tubes.
• Reduction of paint consumption, elimination of booth slurries and associated water treatment costs.
• Dual model
• ACCUBELL Dual allows operation with two separate circuits : a first circuit for water-soluble paints (in the tank) and a second circuit for solvent-based paints (direct line supplied to the rear of the atomizer, via the robot arm), both under electrostatic internal charge. This enables dual startup during production cycles, using both solvent-based and water-soluble products, as well as product-specific solvents.
