CRATER TYRE CT4.0

Patented machinery for processing tyre imperfections

Machinery able to automatically load the tyre from the monorail and bring it inside the cell. Equipped with an advanced 3D scanner, a six-axis robotic arm scans the carcass for impacts and defects to be removed automatically, then performing the treatment with a new machining system that guarantees a faster and more efficient tool change: the robotic arm with the tire, performs the operations by working the rubber on the tools, fixed and interchanged by the new tool center in a faster time, for a more effective treatment. The tools on the market are customizable, such as an abrasive brush and a conventional grinding wheel to eliminate any traces of rust, without damaging the tire’s metal tape. With an impact in terms of improving the quality of work, Crater Tyre CT4.0 is able to increase productivity, reduce costs and preserve the health of operators subject to dirt, fumes, environmental and noise pollution during manual operations via a hermetically sealed cabin.

New tool center: redesigned tool changer that reduces shift times by more than 50%

With Crater Tyre CT4.0, Italmatic Robotics & AGV creates a new generation of shearography machines for non-destructive testing of new and used tyres, from 13″ to 24″.

Plant

The new Crater Tyre CT4.0 is equipped with a tilting system that allows the vertical loading of the tire, faster and more efficient than the traditional horizontal loading, thanks to a system of accumulation rollers, completed by silicone belts, which avoids rubber slipping during the handling process. The machine can be equipped with two different scanning systems depending on the customer’s need to scan the rim or the sides of the tyre. Both scanning systems, in addition to accurately identifying the presence of defects on the tire, highlight their volume, allowing the operator to understand whether the tire is rebuildable or not, detecting defects with relevant size and contour information. The shearography machine software system can interact with external servers, keeping track of the history of the number of defects per tire, from their size to their position on the inspected carcass, identifiable through RFID, barcode or QR-code. From the control panel you can select the tyre scanning area: crown, crown and upper and/or lower side.

The vision system
  1. If the customer needs a tyre crown scan, a special high-performance camera, with a resolution of up to 48MP, provides two 360º rim images: ambient pressure and vacuum to identify defects.
  2. If the customer needs a side scan of the tyre, a high-precision 3D sensor scans the tyre by rotating 360 º, including the lower and upper heels. The scan, a dynamic overview comparable to a special video, allows the operator to analyze the tyre sidewall from a single image, provided at ambient and vacuum pressure, for better identification of imperfections. A better technique than that used by competitive machines, which perform sector scans. Both scanning systems, in addition to accurately identifying the presence of defects on the tire, highlight their volume, allowing the operator to understand whether the tire is rebuildable or not, detecting defects with relevant size and contour information.

“Thanks to Crater Tyre CT4.0, we have improved our productivity, increased production quality, improved the health and safety of our operators. This way you can reduce the number of defects and simply shorten the time of debridement, which is the longest operation in the reconstruction process. Unlike humans, robot intervention is done in a non-aggressive way”
