An end to jackstraws with bottles
What is the point of the best inspection when the rejector is not able to react on time and correctly? Nothing at all! Even though many regard a rejector only to be a simple device HEUFT gave it the attention it deserves right from the beginning. It can be clearly demonstrated by means of the HEUFT DELTA-K and the HEUFT DELTA-FW that there is more to rejecting and laning than simply "container kicking".
The HEUFT DELTA-FW is particularly suitable for full containers. In the case of a rejection individual elements extend one after the other horizontally out of the casing forming a following-on rejection curve along which the product to be rejected glides. The container is thus gently diverted onto the other lane in exactly the same way as it is when it is being directed through the guide rails. The complete rejection curve does not take up position during this procedure: the segments which just touch the container or are directly next in line to touch the container are only ever extended. The elements almost reach the conveyor and therefore they can also clear lying bottles, broken bottles as well as foreign objects from the conveyor. In this way HEUFT makes a considerable contribution towards fault clearance during production.
In fact the HEUFT DELTA-K also works with the virtual rejection curve but its technique is a little different: in this case the individual rejection elements fold out one after the other horizontally from above and also form a rejection curve. The elements have a smaller area of contact which can be adapted exactly to the product by means of the vertical and horizontal adjustment devices. This makes it a specialist as regards the rejection of large empty containers or containers which are unstable due to their shape or even when container shapes which differ considerably are being processed.
Both systems can be used for rejecting faulty containers as well as distributing containers onto two lanes. They also have the technical know-how which was used during their development in common: thus the number of activated segments is selected depending on the conveyor speed. A greater number is required in the case of a lower speed and a smaller number in the case of a higher speed in order to initiate a change in direction and with it a conveyor change.
Furthermore HEUFT developed a principle with the HEUFT DELTA-FW in order to avoid unnecessary wear and tear and passed this on to the other rejectors: the system only works when it is really necessary. The rejection curve is initiated before the first container and remains until the last container to be rejected has been taken to the second lane by it when several containers have to be rejected directly one after the other.
