Window fixtures coating Robot programming

"How easy is it to programme a coating robot?"
Given their considerable size, being able to hang doors and windows is essential. Moreover, overhead lines allow both sides to coated.

"Can I coat my windows assembled or disassembled?"
Coating can be done either way without any shape or size restrictions. It's this aspect, in fact, that makes overhead lines so advantageous.

iGiotto anthropomorphic spraying robot and cVision 3d reading barrier: the winning duo

iGiotto anthropomorphic spraying robot and cVision 3d reading barrier: the winning duo

Achieving coating quality and consistency, together with the highest production efficiency and minimal downtime is the major issue facing companies who are coating complex 3D objects, as well as windows and doors.

Coating robot with cVision iGiotto

iGiotto when used in conjunction with our exclusive cVision 3D Reading Barrier ensures time savings through coating process automation, improves the quality and consistency, thus leading to reduced lacquer consumption and lower costs. Faced with the following key issues, companies can become instantly more competitive by investing in a system where special software and automation provide immediate benefits.

These are the main challenges we have addressed:

• PROGRAMMING
Today’s options allow you to manually program a robot by physically guiding its spraying arms around the complex geometrical shape. The robot learns how to move and replicates the movement piece after piece. You can also program point-to-point trajectories using a software off-line, but each batch will require your manual intervention to enter data into the software to obtain the coating parameters.

• COATING
Apart from the cost of a skilled operator, manual spraying of window frames often leads to fluctuating yields and coating inconsistency. Lacquer consumption frequently exceeds the optimal amount by 15 to 30%, leading to high filter replacement and disposal costs.

• OUTPUT
Production batches can often be small or customised. Operators will need to stop the line for colour changeover or to re-program the trajectories.

All this is an obstacle to production efficiency and incurs costly downtime. So let’s see how we have solved these issues:

cVision avoids the need to manually program an anthropomorphic robot. This means no time at all spent defining trajectories. It’s all done automatically. cVision acquires the 3D image of the piece to be coated and uses its special software to determine the best trajectories. You save time (at least 50%), can be sure of obtaining optimal parameters and consistent coating quality from the first piece to the last. When iGiotto comes into play, the robot capitalises on the accuracy and optimisation of the pre-defined trajectories. In the case of doors, spraying with the new 3-gun wrist now saves considerably on lacquer consumption and ensures the best possible quality and consistency. Colour changes can be performed without even stopping the equipment, even for different products, so downtime is eliminated. And as new pieces enter the overhead line, the software makes sure iGiotto can switch from one piece to the next and one colour to the next without interrupting production.

iGiotto
iGiotto is a complete spray coating system for water-based and solvent-based products using an anthropomorphic robot designed to paint large-sized objects such as doors, window frames or objects with a complex shape, and materials other than wood. Products transit on overhead lines and exit the spraying area into a drying tunnel before being collected in batches. Constant speed and constant distance between the spray guns and the product optimise lacquer consumption and ensure coating consistency. In environmental terms, lower consumption and less waste improves sustainability. 

cVision
The latest-generation, automatic 3D reading system (laser + camera) acquires position, size and shape of pieces in transit with unprecedented precision. The combined action of the laser and ultra-high resolution cameras allow iGiotto to automatically generate precise work trajectories based on the “recipes” of objects present in its database.

An articulated process for a straightforward product – veneered skirting boards

An articulated process for a straightforward product – veneered skirting boards

Baseboard spray painting

One look at a skirting board and the finishing process it undergoes does not immediately come to mind, yet there is a lot to consider when defining an integrated finishing line for this product. One of the many possible solutions serves simply as an example. Each customer we have dealt with has a slightly different objective, so we like to evaluate each case separately. Standard solutions never seem to give more than standard satisfaction, whereas we at Cefla Finishing want to be sure we exceed the customer’s expectations, so we conceive the solution carefully, adapting a feature to solve a problem or adding a function to deliver a better result.

Starting with a brushing machine, we would then move on through a linear spraying machine. The first coat will probably be UV polyacrylic and Performa will apply it at 100 g/sqm. A seven-minute flash off in a Cross oven will then be needed, followed by a UV curing stage. The top side of the profiles will then be sanded on the brushing machine, a topcoat will be applied on the Performa and the flash off repeated for 7 minutes in the Cross oven. Running at speeds between 3000 and nearly 5000 pieces/shift, this is just one approach to finishing veneered skirting boards.

Coating doors and kitchen cabinets: changing the rules to save money

Coating doors and kitchen cabinets: changing the rules to save money

None

Until recently raised panels used for kitchen cabinet doors or even standard doors with raised sections or grooves on the surface were spray coated, start to finish. The process involves various application steps for base and topcoats, sometimes differing according to whether the finished effect is glossy or matt. It also foresees sanding operations between two base application steps and involves a fair bit of handling by operators. Streamlining this process with a hybrid line made up of roller coating and spray coating equipment increases overall efficiency and reduces operator intervention. But how can you process raised panels with a roller coater?

If this were possible, savings could come from less lacquer consumption because whereas transfer efficiency using spray coating equipment may exceed 60%, roller coating procedures ensure even better transfer efficiency and thereby cut lacquer-related costs in comparison.

However, roller coating for raised panels was unheard of until the Smartcoater PRO family of roller coaters adopted the soft rubber application roller technology. This innovation has led to a change in the rules and companies are beginning to adopt the technology which has proven in our laboratory tests to achieve savings on lacquer consumption of up to 1€/sqm.

Equipped with a soft rubber application roller, Smartcoater PRO is able to shorten the coating process:

  • avoiding the need for sanding between base coats, 
  • avoiding the need to deal with poorly calibrated panels,
  • reducing the handling operations,
  • reducing lacquer and solvent consumption,
  • and reducing lead times.

And this is possible on kitchen cabinet doors and other substrates with 10 mm grooves.

Simple, sustainable and top quality: Smartvacuum changes the paradigm

Simple, sustainable and top quality: Smartvacuum changes the paradigm

Smartvacuum Technology Cefla Live

Approximately 80% of today’s kitchen cabinet doors or bathroom cabinet doors are no longer raised panels, but simple, smooth flat panels with slightly rounded edges. Essential design, which deserves high-quality coating, especially when matching the edge coating with the surface coating.

But why introduce vacuum coating technologies when the market is used to roller coating, spray coating or curtain coating? Let’s take a look at the reasons behind this innovation.

Which application are we talking about?

Ideal for 100% UV basecoats, vacuum coating with SmartVacuum deposits 100/140g / sqm of lacquer in a single step. Much less than what you would consume if you were spray coating. No solvents either, so just one stage in and out of the vacuum coater and on to flash off. This reduces costs, lead time and streamlines the coating process.

Where next?

Straight on to the edge coater. SmartEdge will then apply 100% UV lacquer to the panel’s edge using vacuum coating technology once more, achieving an excellent match between panel surface and panel edge, something which was almost impossible until now. Currently edges are slightly rounded, with a 2-3 mm radius usually; vacuum coating both sections increases panel quality and decreases process times and costs.

Sustainability also saves money

On one hand, the idea behind SmartVacuum is a means of lessening the environmental impact by preferring solid 100% UV coatings to avoid solvents. On the other hand, this positively impacts costs. Less lacquer: far less compared to spray coating, and depending on which process it is compared to. It also means less need to stock all those canisters of lacquer and solvent. It also means fewer machines: one SmartVacuum and oven to flash off followed by one SmartEdge for application on the edges.

Simplicity also means quality

By simplifying the process, the introduction of vacuum technology to coat flat panels and edges leads to superior quality. Using the same technique for both surface and edge clearly enables a perfect match which is immediately visible. Moreover, the stability of UV lacquers is better than those used currently, so the quality finish obtained will also last much longer.

If you are interested in learning more about the potential SmartVacuum offers for flat panel coating requirements, we will advise you on the best configuration and choice of consumables, based around your specific needs and business objectives. Contact us today.
