Intralogistic: New developments

Prefeeder ADVECTORVerto with Stack Turner
The Prefeeder ADVECTOR ensures an optimal feeding of the sheets to printing lines, inliners, flat-bed and rotary die cutters in packaging plants. MINDA is continuously developing this machine and offers the unique feature of a lateral infeed of the stacks so that the ADVECTOR can be fed from three sides and used under very limited space conditions. Further developments among the converting machines allow two-sided processing of the corrugated sheets. As a result, MINDA has integrated a stack turner into the Prefeeder this year. The ADVECTORVerto provides the opportunity, depending on the applications, to either activate the turning function or to transport the stack to the downstream converting machine in a continuous shingling flow without any turning.
Toothed conveyors for exact stacks
MINDA developed conveyors with toothed chains for customers requiring absolutely exact stacking patterns. The tooth system ensures a very gentle transport, avoids the creation of sheet-walk effect and moreover, it prevents that sheets are pulled between the conveyors. The toothed plastic chains can be installed on all conveyor elements, such as transfer cars, feeding units for pallet loading etc.
One palletizing robot for two machines
In the corrugated and cardboard industry palletizers must work with high precision but also be robust and flexible. For 10 years, MINDA has cooperated with the company Maschinenbau und Konstruktion GmbH Elmshorn (MuK) in this field. Numerous projects have been successfully realized, creating stacks behind inliners, flat-bed and rotatory die-cutters fully automatically. In 2015 both companies implemented another development for the automation of existing machines.
One robot is installed behind two machines or a miniline. The feeding of die-cutters, for example, is realized by a common Breaker line or via an already existing designated line. Per machine, one storage tower is integrated for the intermediate storage of at least one pallet loading. The robot then calls the buffered load upon demand. Thus, the advantages of robot palletizing can be provided in the area of already existing machines with manageable costs for the storage tower, as two machines share one robot.
The high flexibility and the low spare requirement of the robot justify the integration into an already installed machinery line.
