Krones Robobox: for neat grouping
Wednesday 30. April 2008 - Fully automated pack grouping system
For fast, reliable grouping of non-returnable packs, the newly developed Robobox pack grouping system from Krones AG, Neutraubling, Germany, provides a compactly dimensioned, flexible functional unit for pack distribution and turning, offering maximised scope for any variant of pack grouping. Since the grouping system has been designed to feature series-connected modules for three different output gradations, the concept can be optimally customised for any desired line speed, thus ensuring a high degree of flexibility in conjunction with the downstream palletising system.
Sensitive packs, in particular, like shrink-packs containing PET bottles with a petaloid base, are transported with optimum efficacy and guided to the correct position on the flush-grid-belt conveyor. Whats absolutely new about the Robobox is this: during the entire turning and distribution operation, the packs are positively guided by a gripper. The traversing unit can handle packs measuring up to 400 x 400 mm, with a maximum pack weight of 18 kg. The packs arrive in single file, long side leading. Depending on the layer pattern and pack size involved, several packs can also be positioned simultaneously. The Robobox enables packs to be grouped without requiring any specific components for the palletising patterns, such as spacing devices, stops, etc. This makes it a whole lot easier to introduce new layer patterns and to maximise the spectrum of handling options without elaborate change-over procedures. The Robobox can also handle the tasks of a pack distribution unit or sorting system when several lines are linked up.
Modularised construction for different output gradations
The Robobox pack grouping system is designed for modularised construction, with a module length of 2,200 mm and a speed of up to 2,000 cycles an hour each, resulting in an output range of 2,000 to 6,000 cycles an hour with three series-connected modules and single-pack grouping. When up to three packs are being handled simultaneously, the output can even reach 12,000 packs an hour. The fact that the pack throughput speed may be higher than the systems cycle speed depends on the palletising pattern involved, which may allow packs to pass through without changing their position, and on the options for turning and distributing packs in pairs for each module. The modularised construction also enables the output to be subsequently increased by an upgrade job incorporating additional modules.
