Innovations at drinktec 2022
- Inspection of the application angle by means of index markings
- Washdown design for splash water protection of inspection systems
- New separation methodology for tethered cap inspection
At drinktec in Munich (Sept. 12-16, 2022), we will present our wide range of vision inspection systems for the plastic packaging industry . At booth C5.135, we will provide information on the CapWatcher FC, a system for use in the wet area of filling lines, which for the first time brings a new inspection technology as well as the washdown design for high splash water protection. "In recent years, we have further expanded our expertise in the wet area and developed our inspection systems based on our extensive project experience," says Dr. Gerd Fuhrmann, CEO at INTRAVIS.
CapWatcher FC: new inspection technology works with index markings
With the CapWatcher FC, we introduce for the first time a new inspection technology that uses index markings to inspect the application angle. With the help of five side cameras, the system detects whether the closure is screwed on in the target position or whether it has been screwed on too far or not far enough. The vision inspection system is guided by markings on the closure and neck support ring that are barely perceptible to the end user. If these markings are within a tolerated range of each other, the system assumes that the closure has been completely and correctly fitted and releases the bottle for packaging. The production line operator also receives comprehensive statistics correlating the average application angle with the capper's tool. This allows malfunctions of a tool to be detected at short notice. In addition, the CapWatcher FC inspects the bottle for damage, presence and correct positioning of the closure, and records the fill level of the bottle.
New washdown design for high splash protection
The CapWatcher FC is completely designed in the new washdown design. Dr. Gerd Fuhrmann: "The washdown design is intended for INTRAVIS systems that are located exclusively in the wet area of the filling lines behind the filler. Thanks to the specific design, the inspection unit and the associated control cabinet are splash-proofed all around and meet the hygienic requirements of the fillers." The design also simplifies cleaning of the system as the exterior is designed to drain off any water. In addition, the interior of the CapWatcher FC is easily accessible.
Besides the CapWatcher FC, the label inspection system LabelWatcher is now available in the washdown design, too. Janina Orlowski, Product Manager at INTRAVIS: "With the washdown design for the LabelWatcher, we are once again significantly expanding its application possibilities. Each component is individually enclosed and thus optimally protected during ongoing operation and cleaning." The LabelWatcher is already established in the market and is used for the comprehensive decoration inspection of bottles, jars, cans and containers.
CapWatcher Q-Line: new separation methodology for tethered caps
Additionally, we will present our new and further developments of the CapWatcher Q-Line at drinktec, which is tailored to the challenges of tethered cap inspection. An exhibit of this inspection system for caps will be shown at the booth C5.319 of Sumitomo (SHI) Demag Plastics Machinery GmbH.
The way the closures are separated during an inspection presents a new feature. Whereas the system previously used a star wheel to separate the caps from above, a form-fit, lateral star wheel separation is now selected. Gerd Fuhrmann: "The external shape and stability of tethered caps pose a challenge for separation, especially as the caps are becoming thinner and thinner. With our new form-fit, lateral star wheel separation, our systems ensure perfect separation and positioning of the caps even at the highest speeds. In the process, the closures are handled gently and carefully. "Due to a software logic that has been optimized for the non-rotationally symmetrical outer appearance of the caps, tethered caps no longer have to be aligned. This further simplifies the separation process.
Patented microhole inspection
The CapWatcher Q-Line is also designed to meet other specific requirements for tethered caps. For the inspection of caps with internal closure aids, so-called CAM's, an electrode that is immersed in the cap is no longer required. Our patented non-contact microhole inspection detects microholes and thus prevents damage to the inner closure elements.
The CapWatcher Q-Line can be used flexibly for numerous different cap designs - regardless of whether the caps are injection molded or compression molded, whether they are single- or multi-part, and whether the cap elements are molded or cut.
