Dressed with success
Not many automation companies have been asked to dress a whole population. When RNA s partner SVIA were contacted with a request to handle vests for the toy citizens in the Playmobil family, it was both a fun and challenging task to take on. The request came from the company Tampoprint who have a long and successful cooperation with Playmobil.
Tampoprint supply machines for printing and have many printing machines in production in the Playmobil factories world wide. Tampoprint have proven to be an innovative partner to Playmobil over the years, presenting many new ideas and concepts that has developed the production process.
Challenge
The reason why this particular application has been difficult to automate is down to the large number of component variants. As in real life the toy people in the Playmobil family have a diversified taste and different outfits depending on if they should play their lives as firemen, pirates or school teachers. The request from Tampoprint was to feed approximately 15 different types of small plastic vests of every type available with 10 different colours, into a Tampoprint machine. Thus, the opportunity to optimize the use of vision guided robots to handle the vests becomes very attractive.
Solution
To handle the small vests, SVIA offers their flexible feeder MiniFlex, where a feed system and a robot combined with SVIA s specially developed vision system for robot guidance are utilised. The vision system, PickVision, gives eyes to the robot that can see and pick almost any product. A buffer is simply filled with components and then separated and fed onto a camera conveyor using vibratory linear feeders. The camera then identifies the position of the component including rotation and picks directly from the conveyor with accurate high precision.
Components that are lying in a difficult pick position or on top of each other will be recycled back to the buffer zone. The MiniFlex is a very compact standard in design and construction well proven solution developed for this type of task. For larger components or applications with faster cycle time SVIA can offer alternative standard machines, each of which is developed to match almost any specification. SVIA systems supplied around the world feed components from 1g up to 85 kg and the cycle time can be as short as 0.5 seconds per pick. In the Playmobil application the MiniFlex handles 1200 vests per minute to the printing machine.
Another clear advantage of the system is the simplicity to teach in new components. SVIA delivered the system with 5 components fully programmed and tested; remaining components in the range were programmed in house by the customer in 15 minutes.
The flexibility of the SVIA system offers new opportunities to automate the feeding of components into Tampoprint machines.
